Abstract:
This dissertation makes use of data from three large and detailed rural household surveys conducted in Haiti to examine elements of economic behavior in poor rural households. We use the earliest survey to formulate a set of hypotheses and use statistical meta-analysis to test them against all three surveys. Results in the areas of household vulnerability, form, migration, and education contribute to theory-refinement in Economic Anthropology.

Full text
Abstract:
This thesis contains three studies that provide theoretical and empirical evidence on household decisions in housing and investment portfolios in China, using 2010-2014 data from the China Family Panel Studies (CFPS). The first study investigates regional disparities in homeownership and value of owner-occupied housing in Chinese cities by using panel data from 2010-2014 CFPS. The results show that demographic characteristics actively shape the housing outcomes of urban households in different regions. The results also reveal development trajectories of regional economies. The findings indicate that while urban households benefit from an emerging population and an enormous growth in the private sector in the Eastern and Central regions, in the Northeastern region households are hindered in homeownership by an ageing population and an economy dominated by oversized but inefficient state-owned enterprises (SoEs). The second study adopts a nested logit approach, applying three data sets from the 2010-2014 CFPS. This approach explores how household investment choice differs with personal and household characteristics (e.g., such as health, demographic features, and institutional factors) across the broad investment categories of financial assets, private businesses, and real estate. I also employ a sub-sample from the 2012 CFPS that is restricted to parental households to examine how parenthood alters household investment decisions by building a binomial logistic model. The empirical results show that migration and income have a positive effect on investment decisions in the nested logit models. The evidence from the subsample finds that there are significant differences in the impact of demographic composition between investment categories. Using the 2010-2014 CFPS panel data, the third study investigates how household investment holdings vary according to demographic composition and intra-household bargaining strength in urban China. In addition, to explore the allocation of household investment, a further examination is carried out in the fixed-effect model with the specification of the Working-Leser function and in a Tobit model with two limits. Empirical evidence supports the following hypotheses: (a) changes in demographic composition considerably alter household investment holdings; and (b) the existence of a higher proportion of female children is strongly associated with an increase in household investments in financial assets.

Abstract:
Background: Influenza viruses cause substantial mortality and morbidity both worldwide and in Hong Kong. Furthermore, the possible emergence of future influenza pandemics remains a major threat to public health. Some studies have estimated that one third of all influenza transmission occurs in households. Household studies have been an important means of studying influenza transmissions and evaluating the efficacy of influenza control measures including vaccination, antiviral therapy and prophylaxis and non-pharmaceutical interventions. Household studies of influenza can be categorized as pertaining to one of two designs: household cohort and case-ascertained. In household cohort studies households are recruited before the start of an influenza season and then monitored during the influenza season for influenza infection. In case-ascertained studies a household is enrolled once influenza infection is identified in a household member. Objectives: This thesis comprises of two parts. The objective of the first part is to evaluate the resource efficiency of different designs for conducting household studies. The objective of the second part is to estimate community and household transmission parameters during the 2009 A(H1N1) pandemic in Hong Kong. Methods: Monte Carlo simulation parameterized with data from influenza studies in Hong Kong was used to compare the resource efficiency of competing study designs evaluating the efficacy of an influenza control intervention. Approaches to ascertaining infections in different types of studies, and their implications for resource efficiency were compared. With regard to the second part, extended Longini-Koopman models within a Bayesian framework were used on data from a Hong Kong household cohort study conducted from December 2008 to October 2009. Household and community transmission parameters were estimated by age-groups for two seasonal influenza strains circulating in the winter of 2008-09 and two seasonal and one pandemic strain circulating in the summer of 2009. Results: Simulations showed that RT-PCR outperformed both serology and self-report of symptoms as a resource efficient means of identifying influenza in household studies. Identification of influenza using self-report of symptomatology performed particularly poorly in terms of resource efficiency due to its low sensitivity and specificity when compared to laboratory methods. Case-ascertained studies appeared more resource efficient than cohort studies but the results were sensitive to the choice of parameter values particularly the serial interval of influenza. In statistical analyses of household data during the winter of 2008-09, it was found that transmissibility of seasonal influenza strains were similar to those previously reported in the literature. Analysis also showed for the summer 2009 the estimates of household transmissibility were similar for seasonal A(H3N2) and pandemic A(H1N1) especially after taking into account that some individuals were likely immune to infection. Conclusions: Careful consideration of study design can ensure that studies are resource efficient and have sufficient statistical power. Data from a household study suggested that during 2009 seasonal and pandemic influenza had similar transmission patterns.

Abstract:
High precision data from household travel survey (HTS) is extremely important for the transportation research, traffic models and policy formulation. Traditional methods of data collection were imprecise because they relied on people’s memories of trip information, such as date and location, and the remainder data had to be obtained by certain supplemental tools. The traditional methods suffered from intensive labor, large time consumption, and unsatisfactory data precision. Recent research trends to employ smartphone apps to collect HTS data. In this study, there are two goals to be addressed. First, a smartphone app is developed to realize a smartphone-based method only for data collection. Second, the researcher evaluates whether this method can supply or replace the traditional tools of HTS. Based on this premise, the smartphone app, TravelSurvey, is specially developed and used for this study. TravelSurvey is currently compatible with iPhone 4 or higher and iPhone Operating System (iOS) 6 or higher, except iPhone 6 or iPhone 6 plus and iOS 8. To evaluate the feasibility, eight individuals are recruited to participate in a pilot HTS. Afterwards, seven of them are involved in a semi-structured interview. The interview is designed to collect interviewees’ feedback directly, so the interview mainly concerns the users’ experience of TravelSurvey. Generally, the feedback is positive. In this study, the pilot HTS data is successfully uploaded to the server by the participants, and the interviewees prefer this smartphone-based method. Therefore, as a new tool, the smartphone-based method feasibly supports a typical HTS for data collection.

Abstract:
Magister Philosophiae - MPhil
In many countries, an enumeration of all household members remains the most important source of population statistics. According to Statistics South Africa, two population censuses and quite a few household surveys have taken place across the country. The quality of data recorded varies according to the operation. Despite great improvement in data collection and analysis capacities,some of the demographic data provided have not been assessed in terms of quality. The aim of this study was to ascertain the accuracy of demographic data on age and sex collected and the coverage during the population census 2001, General Household Surveys (2004 and 2007), Labour Force Surveys (2005 and 2007) and Community survey 2007 in South Africa. Two methods were applied to assess the quality of data. First, the direct method consists of checking the content and coverage (errors during enumeration, errors of exploitation, concordance in questionnaire). Second, the indirect method lies in the calculation of some indexes, age ratios,sex ratios, graphing of population pyramids and sex ratios curves. The indexes are Whipple’s index, Myer’s index and the Combined index of United Nations. Therefore, the main variables of interest are age, sex, place of residence and ethnic groups. Differentials in the quality according to declaration on age by gender, by ethnic group, by place of residence have been explored. This study has identified some variations in different indexes between 2001 and 2007 and has also evaluated the ethnic, gender and regional differentials. Comparison between indexes of each instrument has been done to measure some variations over years. Also, time-space comparisons were conducted across indexes of different instruments. The quality of data on age was better at national level compared to provincial level. Therefore, based on the measurements and patterns observed in the census and surveys data, the study has made some recommendations on the need for an integrated approach to reduce the gap and improve the quality of declarations on age and sex.

Abstract:
Strategies of rural development in China experienced sharp changes in the policies for rural economic reform which began in the late 1970s. Contrary to the previous model of a "pure" socialist way of development, which argued for a single developmental path, the reform policies encouraged diversification. Peasant adaptation to the new situation is examined through the co-existence of three kinds of households, namely subsistence cropping households, cash cropping households and partial agricultural households. The thesis attempts to determine the characteristics associated with the different kinds of households by analyzing survey data collected from five townships in the Pearl River Delta of south China. It also attempts to bring out some theoretical implications of the Chinese experiences of rural development in the past forty years.

Abstract:
This thesis presents a methodology for conducting logistic regression modeling of trip and household information obtained from household travel surveys and vehicle trip information obtained from global positioning systems (GPS) to better understand the trip underreporting that occurs. The methodology presented here builds on previous research by adding additional variables to the logistic regression model that might be significant in contributing to underreporting, specifically, trip purpose. Understanding the trip purpose is crucial in transportation planning because many of the transportation models used today are based on the number of trips in a given area by the purpose of a trip. The methodology used here was applied to two study areas in Texas, Laredo and Tyler-Longview. In these two study areas, household travel survey data and GPS-based vehicle tracking data was collected over a 24-hour period for 254 households and 388 vehicles. From these 254 households, a total of 2,795 trips were made, averaging 11.0 trips per household. By comparing the trips reported in the household travel survey with those recorded by the GPS unit, trips not reported in the household travel survey were identified. Logistic regression was shown to be effective in determining which household- and trip-related variables significantly contributed to the likelihood of a trip being reported. Although different variables were identified as significant in each of the models tested, one variable was found to be significant in all of them - trip purpose. It was also found that the household residence type and the use of household vehicles for commercial purposes did not significantly affect reporting rates in any of the models tested. The results shown here support the need for modeling trips by trip purpose, but also indicate that, from urban area to urban area, there are different factors contributing to the level of underreporting that occurs. An analysis of additional significant variables in each urban area found combinations that yielded trip reporting rates of 0%. Similar to the results of Zmud and Wolf (2003), trip duration and the number of vehicles available were also found to be significant in a full model encompassing both study areas.

Full text
Abstract:
When only whole years of age are recorded in survey data, children who experienced a birthday since the beginning of the school year may appear to be of school-age when they are not, or vice-versa. This creates an error in estimates of school participation indicators based on such data. This issue is well-known in education statistics, and several procedures attempting to correct for this error have been proposed. The present study critiques current practice and demonstrates that its limitations continue to confound educational research and high-stakes policy conclusions: speculative explanations have been proposed for what is actually a measurement artefact. An alternative adjustment strategy is proposed that coherently exploits all available information and explicitly indicates the remaining uncertainty. The application of the method is illustrated by a number of empirical case studies using recent household survey data. These examples demonstrate that the method is feasible, accurate, and that taking survey timing into account can significantly alter how these data are interpreted.

To assist policy makers with evaluating urban development policies and anticipating trends in the evolution of cities, researchers have significantly improved modem urban land-use-and-transportation (LUT) simulations. Despite extensive studies regarding the interdependency of household life cycle stages and moving decisions in demography, most existing LUT simulations do not address households changing life cycle stages when modeling residential relocation behavior. The reasons include 1) the data that capture households and housing transitions is hard to obtain, and 2) the analysis methods are mainly for cross-sectional datasets. This dissertation focuses on these issues and contributes to the literature in three respects: behavior exploration, methodology, and applications to housing and transportation policy analysis. The ultimate goal of this study is to have a better understanding of the relationship between household life cycle stages and their moving decisions when the housing market is heavily regulated with incentives based on age, family structure, and income. This research focuses on the housing market in Singapore as a case and utilizes a new dataset of recent movers. First, this study generates sampling weights both at the individual and household levels to correct sample bias. Then, this study uses discrete choice models to identify key household and housing factors that influence households' moving behavior at the household-level. In order to capture household characteristics at the time of decision-making, the household characteristics for those households that changed structure when moving had to be reconstructed. The results show that household moving decisions are mainly influenced by three sets of factors: life cycle stages, tenure choices and housing submarkets. Finally, this research adopts a Markov Chain Model (MCM) approach to estimate a set of forward-looking moving and tenure transition rates accounting for various issues, such as sample bias and "missing-move" problems. The final results improve the estimate of moving and tenure transition rates in several ways: adding more demographic factors, handling household structure changes, and relaxing the memoryless assumption to accommodate a special feature of the public housing sector in Singapore. I expect that this study will have important implications for LUT microsimulations as well as housing and transportation policymaking. It demonstrates a method to analyze a retrospective dataset of recent movers in order to obtain detailed forward-looking moving and tenure transition rates (which are required for microsimulations). It also demonstrates a way to model household structure changes at the household level without introducing a full set of demographic models at the individual level. This study shows that with detailed moving and tenure transition rates, researchers can better capture the critical interactions between households' moving decisions and government intervention on the housing market. This can improve the current LUT simulations in a way that they can be more sensitive to government housing regulation and support long-term policymaking regarding the spatial distribution of housing and transportation infrastructure.

Thesis (PhD)--Stellenbosch University, 2012.
ENGLISH ABSTRACT: In order to evaluate the extent to which South Africa achieve the objectives of poverty and inequality reduction as well as job creation, up-to-date and reliable data are required. Since the transition, various survey data have been commonly used for these analyses, namely Census, Community Survey (CS) 2007, Income and Expenditure Survey (IES), October Household Survey (OHS), Labour Force Survey (LFS), Quarterly Labour Force Survey (QLFS), General Household Survey (GHS), Project for Statistics on Living Standards and Development (PSLSD), National Income Dynamics Study (NIDS) and All Media Products Survey (AMPS). However, these datasets are not fully comparable, due to differences in the sampling design, sample size, questionnaire structure, methodology to derive labour market status, as well as the way the income and expenditure information was collected. Hence, this dissertation begins by analysing these issues in each survey in Chapter 2. With regard to the income and expenditure information, it was collected differently in the surveys: the recall method was used in all surveys except IES 2005/2006, the only survey that adopted the diary method; respondents were asked to report the actual amount in some surveys but only asked to declare the relevant interval in others; for the former approach, respondents could either declare the single estimate amount or amounts for sub-categories that were then aggregated; for interval data, various methods can be used to determine the amount in each interval. Thus, Chapter 3 begins by discussing the merits and drawbacks of these approaches, as well as how they would affect the reliability and comparability of income and expenditure variables across the surveys. In some surveys (e.g., the two censuses and CS 2007), quite high proportions of households incorrectly reported zero income or expenditure or did not specify their income or expenditure. Poverty and inequality estimates could be influenced by either including or excluding these households from the analyses. Hence, various approaches to deal with these households are examined in Chapter 3. As the surveys typically under-captured income or expenditure when compared with the national accounts income, the validity of the resultant poverty and inequality estimates might be affected. Hence, arguments for and against adjusting the survey means in line with the national accounts mean (e.g. by shifting the survey distribution rightwards) are discussed. As the survey data are, strictly speaking, crosssectional and not designed for time-series labour market, poverty and inequality analyses, it is sometimes argued that the data should be re-weighted to be consistent with demographic and geographic numbers presented by the Actuarial Society of South Africa (ASSA) and Census data. This cross entropy re-weighting approach is discussed in Chapter 3. Finally, the chapter examines the labour market status derivation methodology in all OHSs, LFSs and QLFSs in greater detail, and investigates how the changes across the surveys could possibly affect the comparability of labour market estimates throughout the years. The dissertation then examines the labour market trends since the transition by using the OHS, LFS and QLFS data, and it is found that both the labour force and employment numbers increased in general since the transition, but the latter increase was not rapid enough to absorb the expanding labour force. In addition, the number of narrow unemployed doubled between 1994 and 2009, and the narrow unemployment rate showed an upward trend and peaked at just above 30% in 2003. It decreased between 2004 and 2007, before rising again in 2008- 2009 due to the impact of global recession. Application of the cross entropy approach does not substantially affect labour market trends, suggesting that the trends (including the abrupt increase in labour market estimates during the changeover from OHS to LFS) were either real or took place due to the improvement of the questionnaire to capture the labour market status of the respondents better. Furthermore, the application of the LFS 2000b-LFS 2007b methodology on the earlier surveys reduced the extent of the abrupt increase of the number of broad unemployed and broad unemployment rates during the changeover between OHS and LFS. Finally, the use of the QLFS methodology (which required minor revisions) on the LFSs greatly reduced the extent of the abrupt decrease of unemployment aggregates between LFS 2007b and QLFS 2008Q1, thereby improving the comparability of these aggregates across the surveys. In Chapter 5 poverty and inequality concepts are reviewed, followed by a detailed explanation of the sequential regression multiple imputation (SRMI) technique to deal with households with zero or missing income or expenditure, as well as the derivation of real income, expenditure and consumption variables in each survey. Poverty and inequality trends since the transition are examined in Chapter 6. With regard to poverty, with the exception of AMPS, the poverty trends were very similar across the surveys, that is, poverty increased since the transition, before a downward trend took place since 2000. As far as inequality is concerned, both the levels and trends in the Gini coefficients differed a lot amongst the surveys, as the estimates were very stable in the AMPSs, showed an upward trend in surveys like IESs and GHSs, but first increased until 2000 before a downward trend took place in others (e.g., the two censuses and CS 2007). The levels of inequality also differed when comparing the surveys. The abovementioned poverty and inequality estimates and trends could in part be affected by the various issues discussed in Chapter 3, thus there is a need for careful analysis. The impact of the number and width of intervals in which income or expenditure data are recorded on poverty and inequality estimates and trends are dealt with in greater detail in Chapter 6 by applying various intervals on the three IESs and NIDS 2008. It is found that the number and width of intervals only had some impact on these estimates and trends in some surveys. The effect of adjusting the survey means in line with the national accounts mean is also investigated. Finally, the application of the cross entropy re-weighting technique did not have any significant impact on the poverty and inequality estimates and trends.
AFRIKAANSE OPSOMMING: Data wat op datum en betroubaar is word vereis om te kan evalueer in watter mate Suid- Afrika sy doelwitte rakende die vermindering van armoede en ongelykheid en die skepping van werkgeleenthede bereik. Sedert die politieke oorgang word verskeie opnamedatastelle gewoonlik vir sulke ontledings gebruik, byvoorbeeld Sensusse, die Gemeenskapsopname van 2007, Inkomste- en Bestedingsopnames, Oktober-huishoudingsopnames, Arbeidsmagopnames, Kwartaallikse Arbeidsmagopnames, Algemene-Huishoudingsopnames, die Nasionale-Inkomste-Dinamika-Studie en die Alle-Media-en-Produkte-opnames. Weens verskille in steekproef-ontwerp, struktuur van die vraelyste, metodologie om arbeidsmarkstatus te klassifiseer, asook maniere waarop inligting oor inkomste en besteding ingewin is, is hierdie datastelle egter nie ten volle vergelykbaar nie, Gevolglik begin hierdie proefskrif in Hoofstuk 2 om elk van hierdie kwessies in elke opname te ontleed. Inkomste- en bestedingsinligting is in die opnames verskillend ingewin: In die meeste opnames is respondente gevra om aan te dui hoeveel hulle in die verlede bestee of verdien het, maar in die Inkomste- en Bestedingsopname van 2005/2006 is die dagboekmetode gebruik; respondente is in party opnames gevra om die presiese bedrag te vermeld, terwyl hulle in ander opnames die betrokke inkomste- of bestedingsinterval moes aandui; vir eersgenoemde is hulle gevra om òf die enkelbedrag te verklaar, òf hulle moes ‘n aantal sub-komponente onderskei; vir intervaldata kan verskillende metodes gebruik word om skattings van die inkomste in elke interval te maak. Dus begin Hoofstuk 3 met ‘n oorsig van die voor- en nadele van die verskillende benaderings en ‘n bespreking van hoe dit die betroubaarheid en vergelykbaarheid van inkomste- en bestedingsveranderlikes oor die opnames beïnvloed. In party opnames (bv. die twee sensusse en die Gemeenskapsopname van 2007) dui heelwat huishoudings verkeerdelik aan dat hulle geen inkomste verdien of uitgawes aangaan nie, of hulle spesifiseer nie hoeveel hulle verdien of bestee nie. Ramings van armoede en ongelykheid kan geraak word deur sulke respondent in te sluit of deur hulle uit te laat in die ontledings. Gevolglik word verskeie benaderings in Hoofstuk 3 bespreek om hiermee om te gaan. Omdat opnames vergeleke met die nasionale rekeninge tipies inkomste of besteding onderskat, mag dit die geldigheid van daaruitvoortspruitende armoede- en ongelykheidsramings raak. Gevolglik word argumente vir en teen die aanpsssing van die opname-data om dit in ooreenstemming te bring met die nasionale rekeninge (d.w.s. deur die verdeling na regs te verskuif) bespreek. Ten slotte, omdat die opnamedata streng gesproke kruissnitdata is en nie ontwerp is vir tydreekse van die arbeidsmag, armoede en ongelykheid nie, word soms aangevoer dat die gewigte van die data herweeg moet word om in ooreenstemming te wees met demografiese en geografiese data soos verkry van die Aktuariële Vereniging van Suid-Afrika en sensusdata. Hierdie kruisentropie herwegingsmetode word in Hoofstuk 3 bespreek. Ten slotte ondersoek die laaste hoofstuk die metodologie vir die bepaling van arbeidsmarkstatus in all die OHS, LFS en QLFS opnames in groter besonderhede, en ook hoe die veranderings oor die verskillende opname-reekse heen dalk die vergelykbaarheid van arbeidsmarkramings deur die jare kan beïnvloed. Die proefskrif ontleed daarna arbeidsmarktendense sedert die politieke oorgang met gebruik van die Oktober-huishoudingsoponames, Arbeidsmagopnames en Kwartaallikse Arbeidsmagopnames. Beide die arbeidsmag en indiensneming het sedert die transisie toegeneem, maar die toename in indiensneming was onvoldoende om die uitbreiding van die arbeidsmag te absorbeer. Verder het die getal eng-gedefinieerde werkloses tussen 1994 en 2009 verdubbel, en die eng werkloosheidskoers het ‘n toename getoon en in 2003 ‘n toppunt van 30% bereik. Dit het daarna tussen 2004 en 2007 gedaal voordat dit weer in 2008-2009 gestyg het weens die wêreldreseessie. Die toepassing van die kruisentropie-benadering het arbeidsmarktendense nie noemenswaardig beïnvloed nie, wat daarop dui dat hierdie tendense (insluitende die skielike toename in arbeidsmagramings in die oorgang van die Oktoberhuishoudingsopname- data na die Arbeidsmarkopname-data) werklik was, of anders plaasgevind het weens veranderings in die opnamevraelyste om respondente se arbeidsmarkstatus beter te probeer bepaal. Verder het die toepassing van die LFS2000b tot LFS 2007B metodologie op die vroeëre opnames die abrupte verlaging in die oorgang tussen die OHS en LFS in die getal breed-gedefineerde werkloses en breë werkloosheidkoerse verminder. Ten slotte het die gebruik van die QLFS-metodologie op die LFS (wat kleiner hersienings benodig het) die abrupte verlaging tussen LFS2007b en QLFS2008Q1 aansienlik verminder, en dus die vergelykbaarheid van hierdie groothede oor die opnames heen verbeter. In Hoofstuk 5 word eers ‘n oorsig van armoede- en ongelykheidsbegrippe gegee, waarma die sekwensiële-regressie-veelvoudige-imputasie-tegniek in besonderhede bespreek word. Hierdie tegniek word veral gebruik vir gevalle waar huishoudings aandui dat hulle inkomste of besteding nul is, of waar hulle nie antwoord nie. Daar is ook ‘n bespreking van die bepaling van reële inkomste, besteding of verbruiksveranderlikes in elke opname. Armoedeen ongeleykheidstendense word in Hoofstul 6 bespreek. Rakende armoede is daar, met uitsondering van die Alle-Media-en-Produkte-opname, eenstemmigheid dat dit sedert die politieke oorgang eers gestyg het voor dit sedert 2000 begin daal het. Sover dit ongelykheid aanbetref verskil neigings in die Gini-koëffissiënt baie tussen die opnames, want die ramings is stabiel oor die periode vir die Alle-Media-en-Produkte-opname, styg vir die Inkomste- en Bestedingsopname en die Algemene-Huishoudingsopnames, en styg tot 2000 voordat dit afneem in ander opnames (bv. die twee sensusse en die Gemeenskapsopname van 2007). Vlakke van ongelykheid verskil ook tussen die opnames. Deels kan die genoemde tendense in armoede- en ongelykheid dalk toegeskryf word aan die kwessies wat in Hoofstuk 3 bespreek is. Die effek van die getal en wydte van die intervalle waarin inkomste- en bestedingsdata ingewin word op ramings van armoede en ongelykheid word in meer besonderheid in Hoofstuk 6 bespreek. Deur die toepassing van verskillende intervalle op data van die drie Inkomste- en Bestedingsopnames en die Nasionale-Inkomste-Dinamika-studie word bevind dat die getal en wydte van intervalle ‘n beperkte effek op hierdie ramings en tendense het. Verder word gekyk na die effek van die aanpssing van die opname-data om dit in ooreenstemming met die nasionale rekeninge te bring. Ten slotte word getoon dat die gebruik van die kruisentropie-metode nie enige beduidende uitwerking op armoede- en ongeleykheidsramings en -tendense het nie.

ENGLISH ABSTRACT: Achieving food security and reducing hunger requires comprehensive measurement for proper identification of the food insecure, the severity of food insecurity, its causes, and progress in reducing food insecurity. Measuring food security is challenging due to its multidimensional nature as all four dimensions (availability, access, utilisation, and stability) need to be achieved simultaneously. Comprehensive measurement has not been achieved as most existing indicators have a unidimensional focus and efforts to find a ‘composite indicator’ (a catch all measurement tool) have thus far been unsuccessful. This study therefore identified how the three most widely used indicators of food security, the Household Food Insecurity Access Scale (HFIAS), Dietary Diversity Score (DDS) and the Coping Strategies Index (CSI), can complement one other in capturing the multiple dimensions of food security. The study brought them together in one cross-sectional household survey of 409 randomly selected households in Taraba State, Nigeria. The results show that 69 percent of households in Taraba had a very low food security status, 23 percent had low food security, and 8 percent had high or marginal food security. About 34 percent of the households used very erosive coping strategies. Very low food security status was found to be associated with: a household head who is a farmer, less educated, or divorced; low household income and expenditure; large household size; and not owning large plots of land. The survey revealed that most households that obtain the greater proportion of their food from own production, and spend most of their income on the purchase of starchy staples were in the very low food security category. Those that sourced their food mainly through purchase, and spent more on fresh fruit and vegetables, meat, fish, eggs, and processed foods were in the high or marginal food security category. The study showed that the key indicators followed a clear complementary pattern. The bivariate analysis showed a significant difference (P<0.01) in DDS and CSI across HFIAS categories. The HFIAS very low food security category is characterised by the lowest food diversity and highest CSI, revealing that the depth of food insecurity is intense among the extreme group. The study demonstrated that these three indicators can be used together for a fuller understanding of the relationships between the different dimensions of food security, and recommended more studies in using complementary indicators to measure food security. This thesis is presented as the two academic articles option: the first article reviews the measurement of food security and complementarity of the three measures, while the second article discusses the findings of the survey.
AFRIKAANSE OPSOMMING: Die bereiking van voedselsekerheid en die bekamping van hongersnood vereis omvattende meting vir die korrekte identifikasie van voedselonsekerheid, die erns daarvan, die oorsake daarvan, en die proses van voedselonsekerheidvermindering. Die meting van voedselsekerheid is ʼn uitdaging as gevolg van die multidimensionele aard daarvan, aangesien die onderskeie dimensies (beskikbaarheid, toegang, benutting, en stabiliteit) tegelyktydig bereik moet word. Omvattende meting is nog nie bereik nie, aangesien bestaande aanwysers ʼn eendimensionele fokus het, en aangesien pogings om ʼn ‘saamgestelde aanwyser’ (‘n allesomvattende metingsinstrument) te vind, tot dusver onsuksesvol was. Hierdie studie het dus geïdentifiseer hoe die drie mees algemene aanwysers vir voedselsekerheid, naamlik die Huishoudelike Voedselonsekerheid Toegangskaal (HFIAS), die Dieetkundige Diversiteitstelling (DDS) en die Hanteringstrategieë Indeks (CSI), mekaar kan aanvul om die verskeie dimensies van voedselsekuriteit vas te vang. Die studie het die bogenoemde instrumente saam geïmplementeer in ʼn deursnee-huishoudelike opname van 409 ewekansig-geselekteerde huishoudings in Taraba Staat, Nigerië. Die resultate het 69 persent van huishoudings in Taraba met ‘n baie lae voedselsekerheid-status getoon, 23 persent met ʼn lae voedselsekerheid-status, en 8 persent met ʼn hoë of geringe voedselsekerheid-status. Ongeveer 34 persent van die huishoudings het baie verwerende hanteringsstrategieë gebruik. Baie lae voedselsekerheid-status is bevind om meer geassosieer te word met: ʼn huishoudelike hoof wat ʼn boer is, minder opgevoed is, of geskei is; waar daar lae huishoudelike inkomste en uitgawes teenwoordig is; ʼn groot huishoudelike grootte; en die nie-besitting van eiendom. Die opname het geopenbaar dat die meeste huishoudings wat die grootter proporsie van hulle voedsel vanaf eie produksie verkry, en die meeste van hulle inkomste op die aankoop van styselagtige stapelvoedsel spandeer, in die baie lae voedselsekerheid-kategorie geval het. Diegene wat hulle voedsel hoofsaaklik deur aankope verkry het, en meer spandeer het op vars vrugte, groente, vleis, vis, eiers en geprosesseerde kosse, was in die hoë/ geringe voedselsekerheid kategorie. Die studie het bevind dat die sleutelaanwysers ʼn duidelike aanvullende patroon gevolg het. Die tweeveranderlike ontleding het ʼn beduidende verskil (P<0.01) in DDS en CSI oor HFIAS-kategorieë getoon. Die HIFIAS baie lae voedselsekerheidkategorie word gekenmerk deur die laagste voedseldiversiteit en hoogste CSI, wat openbaar dat die diepte van voedselonsekerheid intensief is onder die uiterste groep. Die studie het gedemonstreer dat hierdie drie aanwysers saam gebruik kan word om ʼn beter begrip van die verhoudings tussen die verskillende dimensies van voedselsekuriteit te verkry, en daar is aanbeveel dat meer navorsing onderneem word aangaande die gebruik van aanvullende aanwysers om voedselsekuriteit te meet. Hierdie tesis word aangebied as die twee-akademiese-artikels opsie: die eerste artikel bied ʼn oorsig van die meting van voedselsekerheid en die aanvullendheid van die drie instrumente, terwyl die tweede artikel die bevindinge van die studie bespreek.

Abstract:
National statistics regarding subsidized commuting suggest that employer-based transit subsidies may be inaccessible to the vast majority of the working poor. My main purpose with this study is to increase our understanding of employer-based transit subsidies from a transport justice perspective. I apply the theory of transport justice developed by Karel Martens to evaluate whether the provision of transit subsidies varies significantly by income, and whether the subsidies are significantly associated with accessibility as measured by daily trip levels. I use worker-level data from household travel surveys for 10 of the 22 largest MPOs in the U.S., organized into 7 cases: 1) Atlanta; 2) Baltimore and Washington, DC; 3) Denver; 4) Los Angeles and San Diego; 5) New York and Newark; 6) Philadelphia; and 7) San Francisco. In each of the 7 cases, the odds of being offered a transit subsidy were significantly lower for workers in the 1st income quintile compared to workers in the 4th and 5th income quintiles, even after controlling for other relevant worker and employer characteristics. I found a lack of evidence, in most cases, that transit subsidies are significantly associated with accessibility, both in terms of daily trip levels for low-income workers and daily trip differentials between income groups. Given my finding that low-income workers are the least likely to have access to employer-based transit subsidies, policymakers may consider reform alternatives, such as commuter benefit ordinances, a refundable tax credit for commuting expenses, or alternatives such as income- and location-based subsidies for transit that may support all trip purposes. I hope this study will serve as a reference for policymakers deliberating commuter benefit reforms as well as strategies to support affordable access to opportunities for the working poor.

Full text
Abstract:
This thesis constructs a consistent data set of labour market variables from the annual British General Household Survey for the years 1974 to 1988. It uses this data to investigate the nature and causes of key developments in the distribution of earnings and incidence of unemployment for working age males. The principal findings of the thesis are: (1) Financial returns to education and experience increased substantially during the 1980s, probably due to a large increase in demand for skilled labour. Despite relative losses, real earnings for workers without educational qualifications increased by about 15 percent between 1974 and 1988. (2) After declining slightly during the 1970s, overall earnings inequality increased sharply in the 1980s. The increase in education and experience differentials accounted for only one-third to one-half of the increase in overall inequality. The rest of the rise occurred within education and experience groups. A shift in relative labour demand in favour of workers with high levels of labour market skills again appears to be the most likely explanation. (3) Education and experience levels have an important impact on an individuals probability of becoming and remaining unemployed. Adjusting conventional estimates of the returns to education and experience significantly increases the measured returns to these skills. (4) Once unemployed, changes in the level of unemployment benefits over the range prevailing in Britain during 1979-82 have no measurable effect on the search effort of unemployed benefit claimants.

Abstract:
Cette thèse de doctorat entend proposer trois contributions originales à la littérature théorique et empirique en microéconomie du développement appliquée à l'Afrique. Les deux champs centraux qu'elle aborde sont ceux de l'économie des migrations internationales au Sénégal et de l'économie de l'éducation à Madagascar. Le chapitre 1 traite de la sélection des migrants au sein de leur ménage d'origine et tente d'identifier les principaux facteurs qui président au processus intra-ménage du choix du membre en migration. Le chapitre 2 examine les déterminants sociaux des transferts de fonds des migrants vers leur pays d'origine et analyse plus particulièrement l'influence de la pression redistributive exercée par les ménages d'origine via les réseaux migratoires dans les pays de destination sur la probabilité des transferts et les montants transférés. Le chapitre 3 évalue l'impact à court et long termes du décès d'adultes au sein du ménagé sur les décisions de scolarisation des enfants. Ces trois chapitres partagent comme caractéristique commune une approche microéconomique de la décision et des comportements chez des individus réunis au sein d'un ménage. L'originalité des données exploitées-ROR et MIDDAS -permet non seulement d'apporter un nouvel éclairage sur des questions déjà abordées par la communauté scientifique, mais également d'investir des thèmes de recherche jusqu'à présent insuffisamment explorés faute de données adaptées. Cette thèse met ainsi en évidence l'importance du croisement des disciplines, du travail de terrain et de dispositifs d'enquêtes innovants dans l'investigation de thématiques aujourd'hui à la frontière de la recherche existante
This doctoral thesis proposes three original contributions to the theoretical and empirical literature in development economics in Africa. The two broad fields of investigation are the economics of international migration in Senegal and the economics of education in Madagascar. The first chapter deals with the issue of intra-household selection into migration and aims at identifying the key components that drive the selection of migrants within their origin household. The second chapter investigates the social determinants of remittances and analyzes the influence of the redistributive norms conveyed by the origin household through migrant networks at destination on the likelihood and amounts of remittances. The third chapter investigates the impact of adult mortality within the household on subsequent children schooling decisions over the short and long run. These three chapters ail build on a microeconomic approach of decisions and behaviors among individuals within a household. The originality of the underlying data sets -ROR and MIDDAS -allows not only to bring new insights on some issues that may have been already explored by the literature, but also to tackle issues that have been so far un-or under-explored due to a lack of appropriate data. This thesis therefore highlights the importance of inter-disciplinarity, fieldwork and innovative survey designs in the investigation of original questions at the frontier of the existing research

Abstract:
There was growing concern in New Zealand in the 1990�s that Food Security: access by all people at all times to enough food for an active healthy life, was not being achieved, despite an abundant food supply. A study of a convenience sample of 40 families with children (58 adults and 92 children) whose sole income was a government welfare benefit was undertaken. Two-thirds of these households regularly relied on a limited variety of food; one-half did not have a sufficient amount of food because of lack of money and outstanding debts. Over the previous year two-thirds had sourced food from a food bank and one-third had been gifted food from friends or relatives. Women�s intakes were compromised regularly but not children�s. All of the women experienced worry about feeding their household. One-fifth were overweight and over 40% obese despite low reported daily energy intakes (median (SE) 5.7 (0.5) MJ) compared to national data. Six repeated 24-hour diet recalls collected randomly over a two-week period enabled calculation of usual daily intake and the prevalence of inadequate intake for eight micronutrients which were disturbingly high. The children�s growth patterns compared favourably with US population percentiles. The National Nutrition Survey (NNS97) allowed the adaption of eight questions--developed by Reid using qualitative methods--to eight indicator statements about food security to be addressed by each participant on behalf of them or their household. Prevalence was significantly higher (p<0.05) for females compared to males for the majority of indicator statements among New Zealand European and Others (NZEO) and Maori. NZEO reported the most food security; Pacific people reported the least and Maori fell between the two. There was a significant increasing linear trend of food security with age (p<0.001) after adjusting for gender. Rasch analysis was performed on 1868 households where participants reported some food insecurity. The responses were ranked according to the proportion and ordering of their positive responses to eight indices of food security, achieving reliability (Cronbach�s Alpha) close to the conventionally accepted level of 0.7. The eight indices were ranked on the same scale; the minimum score -1.66 was achieved by the index �use special food grants/banks� (the index least reported and most severe) and the maximum score 1.86 was achieved by the index �variety of foods eaten limited� (the index most reported and least severe). Categories of food security were assigned using scale cut points: �fully/almost fully food secure�; �moderate food security�; �low food security�. Category status was associated with consumption of recommended number of daily serves of fruit, vegetables, fruits and vegetables, consumption of leaner meats, fatty meats and daily serves of bread. By ANOVA and controlling for sex, ethnicity, Index of Deprivation, urban/rural location, age, level of education, income, and household size, category of household food security was associated with the level of daily intake of total fat, saturated, monounsaturated and polyunsaturated fat, cholesterol, glucose, fructose, lactose, vitamin B6, vitamin B12, and vitamin C. Dietary data were from the primary 24-hour diet recall of respondents. Participants in the fully/almost fully food secure category of households had a mean BMI of 28.7 compared to those moderately secure (29.2) and of low food security (29.5) (p=0.015 for difference among categories). In the Children�s Nutrition Survey 2002 (CNS02) data set, the same eight indices were used and food insecurity was experienced significantly more often by children in the largest households, those in the most deprived areas of residence (NZDep01 Quintile) and those of Pacific and Maori ethnicity compared to NZEO children. Rasch analysis was performed on responses for 1561 households with children which reported some food insecurity. Subject reliability was close to 0.7 (the conventionally acceptable level). The distribution of the eight indices on the Rasch scale was similar to that observed among the NNS97 households and almost identical to the sub-set of households with children, from that dataset. Categories of food security status were assigned as in the NN5S97 and they predicted daily nutrient intake levels of children: total sugars, lactose, vitamm A, β-carotene, vitamin B12 and calcium. A more rigorous assigning of categories at the low/moderate scale cut-off, resulted in a further association with level of intake of glucose, fructose and folate. Mean BMI across categories of food security did not differ. Collectively these data provide unequivocal evidence that food insecurity exists in New Zealand, that it can be quantified and associated with nutrition outcomes. It has a negative impact on the nutrient intakes of both adults and children and a negative impact on the body weight status of adults. These data have implications for nutrition and health professionals and policy makers in New Zealand. They also add to the world-wide body of knowledge of the experience of, and the measurement and predictive potential of food security in populations where the food supply appears plentiful.

Abstract:
This research study explored livelihood strategies that female headed households adopt in Magaso village of Mutoko district in Zimbabwe. The study intended to achieve the following objectives: (i) examine the existing livelihood strategies of female headed households (ii) explore the various challenges faced by female headed households and (iii) establish the support mechanisms in place for female headed households to cope with life challenges .The literature reviewed in the study was drawn from several researchers, and the study was shaped by the strengths perspectives and the liberal feminism perspective. The study was qualitative in nature and used interviews to collect data from fifteen (15) female headed households. The data collection process used an interview guide. The research employed a qualitative research design in the form of a case study cum a phenomenological study design. Data was analysed qualitatively using the content thematic data analysis which used interpretive approaches and presentation is textual rather than statistical. The study findings were the following: engaging in subsistence farming was found to be the main livelihood activity of the female heads; engaging in home gardens; exchanging labour for food; involvement in business; reliance on temporary employment from different agencies; reliance on handouts from government and other bodies; and household heads sanctioning child labour that compromises school attendance. Moreover, these female heads faced numerous difficulties ranging from emotional, social to financial problems that resulted in worsening the condition of women, and hence validating feminization of poverty among them. Several support mechanisms were discovered to be available for the female heads but they fail to produce to fruitful results to the lives of the female heads. The study made the following recommendations: mainstreaming gender education from childhood stage; efforts aimed at job creation; financial empowerment through setting up of micro schemes for rural women amongst; seeking the services of agricultural extension services to the female head farmers; improving the social services delivery in Zimbabwe equitably across genders and strengthening informal strategies to improve women‘s social capital. Lastly, the study concluded that little is being done in terms of policy formulation to make the support structures responsive to the female headed households especially in rural areas, hence the need for sustainable development through empowerment.

Full text
Abstract:
Multimorbidity, defined as the co-occurrence of two or more chronic conditions within an individual, is characteristic of an elderly population. Tackling multimorbidity remains one of the key challenges faced by the global community, particularly for many low and middle income countries (LMICs) facing a rapidly ageing population and an onset of non-communicable disease (NCDs) earlier in adulthood than in high income countries (HICs). Using a mixed methods approach, this thesis aimed to understand the prevalence and impact of multimorbidity in LMICs through four studies. The first study examined the prevalence of multimorbidity across 28 LMICs, and its association with socioeconomic status (SES) using education as a proxy. Multimorbidity was found to be positively associated with the female sex and with age, although it was common among younger adults in LMICs. Regional SES analyses also suggested a negative association of multimorbidity with SES. The second study further examined these relationships using the Study of Global Ageing (SAGE Wave 1, 2007-2010), with an additional focus on understanding the effect of urban living in a set of five key MICs: China, Ghana, India, Russia and South Africa. The study findings were consistent with the first study and, in China, points to a pathway of association between urban living and multimorbidity, acting through social, economic, behavioural and demographic risk factors. Using the SAGE, the third study examined the impact of multimorbidity on activities of daily living and functional disability, and found disability to be associated with age and dependent on the chronic conditions included in the multimorbidity count. Drawing on earlier findings, the final qualitative study was carried out within Greater Accra, Ghana. In total, 20 women were recruited from 3 polyclinics across urban, rural and peri-urban areas; and their experiences of living with multimorbidity were explored. The findings highlighted their reliance on the healthcare system in spite of inconsistent coverage, complexity and treatment burden; and their need for social support and holistic care. The aims of this thesis are wide-reaching, and consider evidence for better health planning, policy, and community interventions; particularly for LMICs facing a multimorbidity burden.

Full text
Abstract:
The purpose of this research is to develop and test a widely available, ready-to-use method for adjusting the Institute of Transportation Engineers (ITE) Trip Generation Handbook vehicle trip generation estimates for urban context using regional household travel survey data. The ITE Handbook has become the predominant method for estimating vehicle trips generated by different land uses or establishment, providing a method for data collection and vehicle trip estimation based on the size of the development (e.g. gross square footage, number of employees, number of dwelling units). These estimates are used in traffic impact analysis to assess the amount of impact the development will have on nearby transportation facilities and, the corresponding charges for mitigating the development's negative impacts, with roadway expansions, added turning bays, additional parking or traffic signalization, for example. The Handbook is often criticized, however, for its inability to account for variations in travel modes across urban contexts. For more than fifty years, ITE has collected suburban, vehicle-oriented data on trip generation for automobiles only. Despite the provision of warnings against application in urban areas, local governments continue to require the use of the ITE Handbook across all area-types. By over predicting vehicle traffic to developments in urban developments, developments may be overcharged to mitigate these developments locating in urban environments despite the lower automobile mode shares, discouraging infill development or densification. When ITE's Trip Generation Handbook overestimates the vehicle impact of a development, facilities are also overbuilt for the automobile traffic and diminishing the use of alternative modes. When ITE's TGH underestimates this impact, adjacent facilities may become oversaturated with traffic, pushing cars onto smaller facilities nearby. Currently, there is momentum amongst practitioners to improve these estimation techniques in urban contexts to help support smart growth and better plan for multiple modes. This research developed and tested a method to adjust ITE's Handbook vehicle trip generation estimates for changes in transportation mode shares in more urban contexts using information from household travel surveys. Mode share adjustments provide direct reductions to ITE's Handbook vehicle trip estimations. Household travel survey (HTS) data from three regions were collected: Portland, Oregon; Seattle, Washington; and Baltimore, Maryland. These data were used to estimate the automobile mode share rates across urban context using three different adjustment methodologies: (A) a descriptive table of mode shares across activity density ranges, (B) a binary logistic regression that includes a built environment description of urban context with the best predictive power, and (C) a binary logistic regression that includes a built environment description of urban context with high predictive power and land use policy-sensitivity. Each of these three methods for estimating the automobile mode share across urban context were estimated for each of nine land use categories, resulting in nine descriptive tables (Adjustment A) and eighteen regressions (Adjustments B and C). Additionally, a linear regression was estimated to predict vehicle occupancy rates across urban contexts for each of nine land use categories. 195 independently collected establishment-level vehicle trip generation data were collected in accordance with the ITE Handbook to validate and compare the performance of the three adjustment methods and estimations from the Handbook. Six land use categories (out of the nine estimated) were able to be tested. Out of all of the land uses tested and verified, ITE's Trip Generation Handbook appeared to have more accurate estimations for land uses that included residential condominiums/townhouses (LUC 230), supermarkets (LUC 850) and quality (sit-down) restaurants (LUC 931). Moderate or small improvements were observed when applying urban context adjustments to mid-rise apartments (LUC 223), high-turnover (sit-down) restaurants (LUC 932). The most substantial improvements occurred at high-rise apartments (LUC 222) and condominiums/townhouses (LUC 232), shopping centers (LUC 820), or coffee/donut (LUC 936) or bread/donut/bagel shops (LUC 939) without drive-through windows. The three methods proposed to estimate automobile mode share provides improvements to the Handbook rates for most infill developments in urban environments. For the land uses analyzed, it appeared a descriptive table of mode shares across activity density provided results with comparable improvements to the results from the more sophisticated binary logistic model estimations. Additional independently collected establishment-level data collections representing more land uses, time periods and time of days are necessary to determine how ITE's Handbook performs in other circumstances, including assessing the transferability of the vehicle trip end rates or mode share reductions across regions.

Abstract:
Emerging automotive and transportation technologies have provided revolutionary possibilities in the way we might travel in the future. Major car manufacturers and technology giants have demonstrated significant progress in advancing and testing autonomous vehicles in real-life traffic conditions. Governmental agencies are grappling with how to plan transportation systems for a world with autonomous vehicles. Past research has shown that not all technologies are immediately welcomed by the public. Autonomous Vehicles would have to likely go through a similar phase, and would need to overcome not just technological challenges but also social barriers for successful penetration into the marketplace. Most previous studies on consumer opinions, and potential adoption of these technologies provide only descriptive, univariate analyses that fail to extract deeper insights on consumers’ perceptions, and their intended adoption of autonomous vehicles. Multi-population surveys were conducted to obtain data on consumers’ perceptions, their intended adoption, and eventual use of autonomous vehicles. Descriptive results revealed that around one-fifth of the respondents were unfamiliar about this technology, with larger shares of the younger generations expressing unfamiliarity. Questions on intended adoption of autonomous vehicles were asked across two stages of the survey and results revealed the merit of providing information to the recipients which seem to have assisted them in making more informed decisions about their intended adoption (or non-adoption process). 40% of the respondents were unlikely to adopt autonomous vehicles with a further 20% being unsure, presently. When analyzed across generations, it was seen that higher shares of older generations were unlikely to adopt autonomous vehicles than their younger counterparts. In addition to adoption, other interesting insights on use of autonomous vehicles, and travel behavioral implications of autonomous vehicles were also obtained in this analysis. Considering the vast market potential of this technology, it is important to obtain insights on possible differences in adoption (or non-adoption) across various consumer market segments. The current dissertation fills these gaps in the literature by providing an in-depth understanding of the potential market segments of autonomous vehicle consumers, and revealing the factors influencing their adoption (or non-adoption of autonomous vehicles). Two-step cluster analysis of consumers’ perceptions of potential benefits and concerns with autonomous vehicles reveal four distinct consumer market segments – the benefits-dominated market segment, the concerns-dominated market segment, the uncertain market segment, and the well-informed market segment. The insights obtained are further used to uncover various triggers influencing the adoption (or non-adoption) of autonomous vehicles across these market segments. It can be seen that in addition to the influence of sociodemographics, various other factors such as current travel characteristics, crash history, and current vehicle purchase inventory have significant influences in the adoption process across each market segment. The results from this exercise provide autonomous vehicle stakeholders with a more in-depth understanding of the potential market segments interested (or uninterested) in adopting autonomous vehicles, which could be used to develop enhanced marketing and policy initiatives to achieve better outcomes. Considering the high initial cost of autonomous vehicles, novel business models like shared autonomous vehicles (SAVs), could emerge as possible alternatives to individually owning, and operating autonomous vehicles. The recent emergence of popular rideshare giants, such as Uber and Lyft, into the SAV market have further brought some discussion on possible alterations to household vehicle ownership models in a shared environment. Previous research simulating SAV fleets in a gridded city network reveal the cost benefits of having shared autonomous vehicles in comparison to owning and individually operating them. This study looks into the implications of shared autonomous vehicles on current household vehicle ownership and uncovers the factors influencing the relinquishment of a household vehicle to use shared autonomous vehicles for commute trips. Results show that the effect of relinquishing household vehicles is different among single- and multi-vehicle households with different triggers such as socio-demographics, current travel characteristics, crash severities, and vehicle purchase histories influencing the relinquishment of household vehicles.

Abstract:
We take advantage of the fact that for the Austrian SILC 2008-2011, two data sources are available in parallel for the same households: register-based and survey-based income data. Thus, we aim to explain which households tend to under- or over-report their household income by estimating multinomial logit and OLS models with covariates referring to the interview situation, employment status and socio-demographic household characteristics. Furthermore, we analyze source-specific differences in the distribution of household income and how these differences affect aggregate poverty indicators based on household income. The analysis reveals an increase in the cross-sectional poverty rates for 2008-2011 and the longitudinal poverty rate if register data rather than survey data are used. These changes in the poverty rate are mainly driven by differences in employment income rather than sampling weights and other income components. Regression results show a pattern of mean-reverting errors when comparing household income between the two data sources. Furthermore, differences between data sources for both under-reporting and over-reporting slightly decrease with the number of panel waves in which a household participated. Among the other variables analyzed that are related to the interview situation (mode, proxy, interview month), only the number of proxy interviews was (weakly) positively correlated with the difference between data sources, although this outcome was not robust over different model specifications.

Abstract:
The understanding of how households make decisions may improve the success of an economic development program and enhance targeted training efforts. Technology adoption and farm management decisions depend on household decision making. If a relevant decision maker can be clearly identified and specifically trained to meet his or her needs, the development program may be enhanced. Many approaches have been developed to help understand household decision making processes and the responses to household surveys provide the basis for many such approaches. Survey questions are often asked of a single person, and proxy responses are commonly used. Though potential bias from proxy responses is well documented, there is less information regarding the relationship between the proxy and his or her characteristics and the veracity of responses to subjective questions like who makes decisions within the household or who is in charge of major responsibilities. This paper employs the methods of mining contrast-set (Bay and Pazzani, 1999, 2001) and association rule (Agrawal et al., 1993) to answer the general question of whether and under what conditions proxy responses to survey questions are acceptable in a rural area of Ecuador. It also analyzes how factors such as gender of the respondent matters and how other factors affect the suitability of using proxy responses. The findings show that gender matters for farm-household decision making in rural Ecuador. For instance, more male than female respondents are likely to claim that they are responsible for household decision-making. Respondents answer differently not only to some subjective questions such as who sells crops, but also to objective survey question such as the number of female workers in a family. Factors such as the age of the respondent are found to influence responses about certain activities such as preparing and applying pesticides. The pattern of responses to both objective and subjective questions as well as the effect on responses by characteristics differ by areas where the survey is conducted, etc..

Abstract:
Como tentativa para compensar a ausência de resposta, aplicou-se o estimador ponderado por pesos amostrais nos dados de um inquérito domiciliar que registrou uma taxa global de resposta igual a 79,10 por cento . O procedimento procurou viabilizar a aplicação do ajuste ao nível dos elementos, usando os pesos obtidos a partir da taxa diferencial de resposta verificada na amostra composta pelas famílias. Fixado o número de cômodos do domicílio como a variável critério para a formação das classes ponderadas, calcularam-se as médias ajustadas e suas variâncias para o peso e a estatura dos menores de 19 anos, usando-se as estimativas calculadas na amostra constituída pelos elementos pertencentes às famílias que efetivamente responderam ao inquérito. A consistência dos resultados obtidos sugere que estudos devem ser desenvolvidos a fim de buscar soluções que minimizem as pressuposições necessárias à aplicação do procedimento e determinem níveis de abrangência que possam ser considerados satisfatórios.
The weighting adjustment by sample weights was applied on the data from a survey sampling with a total response rate of 79,10 per cent , in order to compensate for the unit nonresponse. The weighting factors were gotten by the differential response rate calculated on the household sample to facilitate the application procedure. The variable used to define the weighting classes was the number of rooms of the dwellings. Also, the adjusted means and their variances were calculaled for weight and height of persons with ages under 19 years, using the measures obtained from the same age group individuals related to the respondent households. The consistency of the results support the sugestion that more research has to be done to search for procedures that will minimize the necessary assumptions that underlie them and that can assure wider application levels.

Abstract:
This is a collection of papers on three Southeast Asian countries, Cambodia, Lao PDR and Thailand. All four studies rely on household survey data for analyzing topics related to poverty and conflicts. Trust and Conflict in Southern ThailandThe insurgency in Thailand’s southern border provinces has caused thousands of casualties since 2004. This paper investigates the impact of mistrust of the government on the violent conflict. I analyze how failure to address local grievances has led to a breakdown of trust and created conditions for an insurgency. Empirical tests are carried out using a survey of individual trust in government institutions conducted at the beginning of violent conflict. It is shown that sub-districts where the population displayed lower levels of pre-conflict trust experienced higher levels of lethal violence during the conflict. Factors influencing trust in government institutions are analyzed using ordinal logistic analysis. Economic and ethno-linguistic factors are identified as the main determinants of trust towards the government. Political polarization in ThailandThe article traces recent political polarization to earlier institutional reforms opening up the political system to increased electoral competition. The increased influence of the rural majority led new political entrepreneurs to introduce welfare policies. The new polices were opposed by urban tax payers, setting off a process of policy driven polarization that drew on underlying cleavages in Thai society. Empirical tests based on voting patterns in the most recent general election using a seemingly unrelated regression model provide support for the hypothesis of policy driven political polarization. The analysis highlights the vulnerability to increased polarization after introduction of institutional reforms that alter the balance of power between different parts of the electorate. Ethnic Minority Poverty in Lao PDREthnic minorities have a significantly higher poverty incidence than the majority in Lao PDR. Based on survey data the determinants of minority poverty are analyzed, the sources of inequality decomposed, and the expected impact of polices to address minority poverty estimated. When economic factors are controlled for, ethnicity does not have any significant effect on poverty. Decomposition shows that unequal access to resources and demographic variables largely explain the majority-minority poverty gap. Rural Poverty in CambodiaCambodia has been growing rapidly over the past few years, but remains one of the poorest countries in East Asia. This paper analyzes rural poverty in Cambodia to identify the factors that explain its occurrence and persistence. The reduction of rural poverty in Cambodia requires (1) improvements in agricultural productivity and (2) the establishment of other income earning opportunities for the rural population. An econometric analysis of the Cambodian Socio-Economic Survey shows that the main causes of poverty differ between landowners and the landless, and between different regions.

Abstract:
A partir de l'objet automobile, cette thèse propose une réponse en trois temps à la problématique du rôle de la consommation matérielle dans la stratification sociale. Grâce aux caractéristiques originales du bien automobile, l'objectif poursuivi est d'interroger la question de l'homogénéisation des styles de vie dans le contexte de la France contemporaine sous trois rapports : les phénomènes de diffusion de l'automobile, la distribution sociale des caractéristiques de l'équipement, la répartition des coûts engendrés par la voiture. Comment caractériser la diffusion d'un objet symbolique de la consommation de masse et quelles sont les limites à cette diffusion ? Comment sont distribués les biens selon leurs caractéristiques dans l'espace social ? Comment varient les différents coûts de l'automobile parmi les groupes sociaux ? Nous répondons à de telles questions en recourant à une analyse secondaires de deux séries d'enquêtes réalisées par l'Institut National de la Statistique et des Études Économiques : les Enquêtes Nationales Transports réalisées en 1981, 1993 et 2007 ainsi que les enquêtes Budget de famille réalisées en 1985, 1989, 1995, 2001 et 2006
By using the automobile as a social object, this thesis provides a threefold answer to the problem of the role of material consumption in social stratification. Thanks to the very original nature of automobile, we aim at address the question of the homogenization of lifestyles in contemporary France in three differents aspects : the phenomenons of social diffusion, the distribution of the characteristics of the automobile in social space and the repartition of the internal and external costs of the car. How can we characterize the diffusion of a good symbolic of mass consumption ? Which limits does this diffusion assume ? How are distributed the characteristics of the material goods in social space ?How do the differents costs of the automobile vary among social groups ? We adress theses questions by using secondary analysis of two series of suveys conducted by the French institute of statistics : the National Travel Surveys realized in 1981, 1993 and 2007 and the French Household Expenditure Surveys conducted in 1985, 1989, 1995, 2001 and 2006

Abstract:
This dissertation deals with consumption in Swedish households between 1913 and 2001. More specifically, it asks whose resources matter most in determining consumption patterns. As a second question, the dissertation also attempts to establish whether the fact that simple covariance between a spouse’s background variables implies that the spouse has any influence at all over the household’s consumption decisions. The theoretical background is mostly drawn from literature regarding intra-household allocations: on the one hand cooperative game theory and on the other hand sociological theory. Cooperative game theory establishes influence, say or power within the household as a function of the marriage’s or cohabitation’s alternative cost, i.e., the difference between the utility level for a married or cohabiting person as opposed to a single person. Sociological theory considers the contribution one makes to the total level of utility in the household, whether in the form of monetary income, household work or as something else. This is in part conceptualized as a difference between exit and voice. The dissertation’s statistical analysis uses three surveys of household expenditure conducted in 1913, 1952 and 1999-2001. They give us an excellent picture of what they actually purchased during that year. The sample sizes are 552, 596 and 3,501, respectively. The dissertation’s main result is that human capital is a previously underestimated determinant of influence in consumption decisions. As the female stock of human capital increases, so does her influence over the household’s consumption decisions. In an attempt to determine the level of democracy within households, the dissertation uses a complementary data source: a questionnaire called “The Swedish People 1955”. Here, one of the questions directed to females was whether they checked with their husbands before deciding on a purchase, as a measure of intra-household democracy. This was then regressed upon the female share of total income, ideological position and two forms of human capital, one general and one for household work. Both forms of human capital lead to democratic households, which is taken to mean that human capital is important not only because it increases labor opportunities in the event of divorce (exit) but also because it increases female voice.

Abstract:
La mobilité quotidienne est au cœur des réflexions sur la durabilité des villes. Moyen de réaliser ses activités quotidiennes et clé de voute des relations sociales, ses aspects économiques, et notamment ce que doivent dépenser les ménages pour se déplacer, sont un enjeu actuel majeur.Cette thèse propose une réflexion sur les interactions entre forme urbaine et mobilité quotidienne au travers du prisme des dépenses de mobilité. Pour questionner ces interactions, deux méthodes sont utilisées, indissociables l’une de l’autre.La première méthode consiste à acquérir une compréhension des effets de l’environnement construit du lieu de résidence sur le budget mobilité des ménages. Les données présentes dans les Enquêtes Ménages Déplacements sont particulièrement adaptées à cet exercice, car elles contiennent une richesse d’information importante sur les individus ainsi que leur mobilité,équipements, opinions et lieu d’habitation. Le terrain d’étude de ce travail est l’aire urbaine de Lyon, qui abrite une grande diversité de territoires et de modes de transport et où sont disponibles de nombreuses bases de données.Tout d’abord, une typologie de territoires a été construite, basée sur les principaux déterminants de la mobilité : densité, iversité, design, accessibilité aux destinations, distance aux transports collectifs et démographie. Ensuite, un cadre d’analyse systémique des relations entre forme urbaine et mobilité quotidienne a été élaboré afin d’identifier trois indicateurs qui permettent de les appréhender : la motorisation, le choix modal et les distances parcourues par modes. La typologiede territoires se révèle fortement explicative sur ces trois indicateurs. Une analyse des évolutions des mobilités entre 1995 et 2015 permet également d’identifier de nouveaux enjeux liés à l’évolution des prix, des comportements et de la démographie.Ce questionnement est ensuite prolongé à travers l’expression et la mesure des mécanismes d’intervention des caractéristiques du lieu de résidence sur le budget mobilité. A l’aide de la technique des modèles d’équations structurelles, les chemins causaux existant entre la forme urbaine locale et le budget mobilité sont explicités. Cette méthode est appliquée sur différentespopulations et types de territoires – ménages actifs puis retraités sur l’agglomération de Lyon puis sur les territoires périurbains – afin d’acquérir une compréhension fine du budget mobilité des ménages.La seconde méthode consiste à tester diverses organisations morphologiques et fonctionnelles du territoire à l’échelle du bassin de vie, afin de mesurer les effets sur le budget mobilité des ménages. Ce travail est réalisé à l’aide d’un modèle d’interaction transport-urbanisme, SIMBAD, qui permet de conduire une analyse systémique et multi-échelles des effets de la forme urbaine sur le budget mobilité. Divers scénarios de forme urbaine sont simulés, participant ainsi au débat sur la durabilité des formes urbaine monocentrique compacte, étalée diffuse et polycentrique dans une logique de Transit Oriented Development.Par ailleurs, les enseignements de la première méthode, c’est-à-dire le traitement des Enquêtes Ménages Déplacements pour étudier les effets de la forme urbaine locale sur le budget mobilité, nous incitent à conduire une analyse multi-échelles des résultats des simulations : une réflexion sur la différenciation des impacts selon l’organisation du territoire et selon le lieu de résidence à l’intérieur de l’aire urbaine est ainsi menée.Ce travail de thèse apporte donc à la fois des éléments méthodologiques pour analyser les interactions entre forme urbaine et budget mobilité, avec la construction de modèles d’équations structurelles et l’usage d’un modèle d’interaction transport-urbanisme dans un objectif de simulation, ainsi que divers résultats et éclairages qui viennent prolonger la littérature scientifiqueexistante
Daily mobility is at the heart of debate on urban sustainability. A mean to carry out our daily activities and a key to social interactions, economic aspects and especially household expenditures linked to mobility are a major current issue.This thesis proposes a discussion on the interactions between urban form and daily mobility through mobility expenditures. Two interrelated methods of analysis are used to investigate these interactions.The first one relies on a comprehensive understanding of the effects of the built environment on daily mobility budgets. Household surveys are especially suited to this analysis because they provide a wealth of information on individuals’ attributes, their mobility, equipment, opinions and housing characteristics. Combined with various local or national databases, it is possible to estimate a household budget for every surveyed household. The case study for this analysis is the Lyon urban area. It contains very different built environments, and hosts a diverse array of transport modes. Furthermore, numerous databases are available for our analysis.First, we build a typology of territories based on the main daily mobility determinants: density, diversity, design, accessibility to destinations, distance to transit and demography. Then, an analytical framework of relations between urban form and daily mobility is built to identify three indicators to apprehend them: motorization, modal choice and distance per mode. This typology of territories is tested on these three indicators and appears to be highly significant. An analysis of the mobility evolution between 1995 and 2015 also identify various new issues related to prices, behavioral and demographic evolutionsThis line of questioning is extended through the identification and quantification of the effects of built environment characteristics on household mobility budgets. Using a Structural Equation Modelling method, causal paths between local urban form and household expenditures are presented. This method is applied to different types of population and territories – workers and retired households of the Lyon agglomeration then on the same types in suburban areas – in order to understand householdmobility budgets.The second method consists of testing various morphological and functional organizations of the territory in order to measure their effects on daily mobility budgets. This work is conducted using a land use and interaction model (LUTI), SIMBAD, which allows us to conduct a systemic and multiscale analysis of urban form on daily mobility budgets. Different scenarios of urban form are thereafter simulated, contributing to the debate on the durability of monocentric, sprawled or polycentric citiesin a Transit Oriented Development urban form. Besides, lessons learned from data processing of Households Surveys encourage us to conduct a multiscale analysis. A discussion on the differentiation of impacts depending on the global form of the territory is conducted.This thesis work presents innovative methodological elements to analyze the interactions between urban form and mobility budgets, including the construction of structural equations models and the use of a LUTI model to simulate urban environments. It also offers novel results, which contribute to the current scientific literature

Abstract:
The transportation community is exploring how new "big'' databases constructed by companies or public administrative agencies can be used to better understand travelers' behaviors and better predict travelers' responses to various transportation policies. This thesis explores how a large targeted marketing database containing information about individuals’ socio-demographic characteristics, current residence attributes, and previous residential locations can be used to investigate research questions related to individuals' transportation preferences and the built environment. The first study examines how household vehicle ownership may be shaped by, or inferred from, previous behavior. Results show that individuals who have previously lived in dense ZIP codes or ZIP codes with more non-automobile commuting options are more likely to own fewer vehicles, all else equal. The second study uses autoregressive models that control for spatial dependence, correlation, and endogeneity to investigate whether investments in public transit infrastructure are associated with higher home values. Results show that willingness-to-pay estimates obtained from the general spatial Durbin model are less certain than comparable estimates obtained through ordinary least squares. The final study develops an empirical framework to examine a housing market's resilience to price volatility as a function of transportation accessibility. Two key modeling frameworks are considered. The first uses a spatial autoregressive model to investigate the relationship between a home's value, appreciation, and price stability while controlling for endogenous missing regressors. The second uses a latent class model that considers all these attributes simultaneously, but cannot control for endogeneity.

Abstract:
The study was premised on the truism that men have historically served in higher echelons of organizational management structures and women are under-represented. The principal objective was to explore the constraints faced by women in accessing higher leadership and senior management positions in public, private and non-governmental organisations in Zimbabwe. This study adopted the triangulation method, that is, qualitative and quantitative approaches. These mixed research methods, were upgraded by the feminist research methodologies, thereby making a contribution in the field of research. The study found out that the constraints that mostly hinder women from accessing leadership and senior management positions in public, private and NGOs were cultural practices, which represent levels of power and control that in turn hinder reforms; and women's socialisation into feminised roles. The study also found out that in most organisations, most females work under male leadership, and this traditional organisational culture, needs to be deconstructed and reversed in order to achieve gender equality. The study recommended for a human centric and integrated organizational management strategy for public, private and NGOs in Zimbabwe. The adoption of a human centric and integrated management approach should aim at gender equity and reduce women's under-representation. A human centred organizational culture has to be practiced, that would create organisational ethos that guide organizational management. An integrated organizational management approach should integrate all systems and processes into one complete framework, enabling people to work as a single unit, unified by organizational goals, shared vision and common values. The system should depend on a balanced mix of the masculine and feminine attributes. The approach should put its weight towards adoption of measures to attract, advance and empower women so as to benefit from their qualifications, experience and talent in a highly competitive environment.

Abstract:
Introdução - A preocupação com a qualidade e disseminação dos dados em inquéritos é crescente no mundo. A integração entre banco de dados, planejamento da amostra, questionário e entrada de dados é fundamental para que resultados observados sejam válidos e precisos. A bibliografia pesquisada apontou que os inquéritos raramente produzem arquivos organizados, padronizados e prontos para disseminação, o que impossibilita estudar diferentes objetos de investigação com base em informações já coletadas. Objetivos - Implementar modelo hierárquico para entrada de dados em inquéritos epidemiológicos. Métodos - Foi utilizada a UML (Linguagem de Modelagem Unificada) para o projeto lógico e o Makeview do Epi Info para obtenção das estruturas de dados. Os testes foram feitos em um setor censitário do inquérito Acesso a Medicamentos - FAPESP. A documentação foi gerada no Makeview com ajuda de uma macro do Excel. Resultados - O modelo permite criar arquivos relacionais flexíveis, conforme a necessidade do objeto de estudo, com unidades estatísticas escolhidas dentre os 4 níveis hierárquicos: setor censitário, domicílios, indivíduos e questões específicas. Conclusão - A possibilidade de criar infinitas visões sobre os dados representa um avanço em comparação com o modelo plano. Deve ser usado como padrão em inquéritos epidemiológicos, pois permite estudar o efeito de conglomeração das unidades de análise, além de viabilizar a disseminação com dados organizados. O Epi Info pode ser usado para implementar modelos hierárquicos que considerem as variáveis do plano amostral.
Introduction - Concern about the quality and data dissemination in surveys is growing in the world. The integration between database, sample planning, questionnaire and data entry is fundamental to the accuracy and validity of the results. The bibliography showed that investigations rarely produce organized files, standardized and ready to dissemination, which makes impossible the study of various investigation objects based on information already collected. Goals - Implement hierarchical model for data entry in epidemiological surveys. Methods - It was used the UML (Unified Modeling Language) for the logical project and the Epi Info Makeview to obtain the data files. The tests were made in a census block of the Access to Medicines - FAPESP survey. The documentation was generated in Makeview with help of an Excel macro. Results - The model allows you to create flexible relational files, as the need to study subject, with statistical units chosen amongst the 4 hierarchical levels: census blocks, households, individuals and specific issues. Conclusion - The ability to create infinite views on the data represents a breakthrough in comparison to the flat files. It should be used as standard in epidemiological surveys, it allows studying the effect of conglomeration of analysis\' units, besides enabling the dissemination with organized data. The Epi Info can be used to implement hierarchical models that consider the variables of a sampling plan.

Abstract:

This study is aimed at empirically examining health seeking behaviours in terms of illness response on household level at South Africa using 2007 General Household Survey and other
relevant secondary sources. It provides an assessment of health seeking behaviours at the household level using individuals as unit of analysis by exploring the type of health care provider sought, the reason for delay in health seeking and the cause for not consulting. This study also assesses the extent of dissatisfaction among households using medical centres and this factor in health care utilisation is considered as the main reason for not consulting health care services. All the demographic and health seeking variables utilised in this study are controlled for medical aid cover because it is a critical variable in health care seeking. Therefore this study makes distinction on illness reporting and they type of health care consulted by medical aid holders and non medical aid holders. Statistical analyses are conducted to explore and predict the way in which demographic variables and socio economic variables affect health care seeking behaviours.

Abstract:
Cette thèse en micro-économie du développement s'articule autour de l'objectif de développement durable numéro 16 visant à «promouvoir l'avènement de sociétés pacifiques et inclusives aux fins du développement durable, assurer l'accès de tous à la justice et mettre en place, à tous les niveaux, des institutions efficaces, responsables et ouvertes à tous ». Elle propose d'étudier, à partir de données d'enquêtes originales et de première main, les interactions et les effets de la Gouvernance, la Paix et la Sécurité pour les ménages et les entreprises des pays d'Afrique subsaharienne. Ce projet s'articule autour de deux axes de recherche. Le premier, transversal et méthodologique, interroge la fiabilité des données utilisées. En effet, ces données portent, d'une part, sur des sujets sensibles (respect des droits fondamentaux, démocratie, corruption…) et d'autre part, elles ont été recueillies par des opérateurs publics : les instituts nationaux de la statistique. Les résultats de ce premier chapitre montrent que les instituts publics sont totalement légitimes pour collecter des données de gouvernance : aucun biais de réponse systématique en faveur (ou en défaveur) des pouvoirs publics n'existe quand les enquêtés sont interrogés par des agents d'organisation publique. Le second axe étudie les conséquences micro-économiques de la violence au travers de deux études de cas. Le deuxième chapitre porte sur la violence d'ordre politique et ses effets sur le capital social au Mali depuis le début du conflit en 2012. L'exposition aux violences renforce les liens forts, exclusifs entre individus d'une même communauté, aux détriments des liens inter-groupe dits faibles, inclusifs qui déterminent le développement économique et social individuel et local. Ce repli sur soi est probablement un facteur de l'enracinement des tensions inter-ethniques qui ont explosé après 2016. Enfin, le dernier chapitre analyse les effets de la violence criminelle sur le marché du travail informel à Madagascar. Alors que les victimes de criminalité ajustent relativement peu les conditions de leur travail, la peur de la violence criminelle, largement partagée dans la société malgache, impacte négativement la productivité des ménages agricoles. Ces derniers adoptent des comportements plus risqués sur le marché du travail. Cette inquiétude a deseffets sur les plus jeunes dont le temps de travail augmente
This dissertation in applied development microeconomics centres on Sustainable Development Goal 16 which “promote[s] just, peaceful and inclusive societies”. This work aims at studying the interactions and effects of Governance, Peace and Security through the analysis of first-hand and high-quality household survey data in SubSaharan Africa. It is built around two lines of research. The first line of research is cross-cutting and methodological: it questions the reliability of the data used. Indeed, public organisations, namely National Statistics Offices, administer the surveys and collect information of sensitive nature (dealing with respect of fundamental rights, democracy, corruption among other things). Results show no systematic self-censorship or attenuation bias from adults surveyed by NSOs compared with adults surveyed by independent organisations. We provide evidence of the capacity and legitimacy of government-related organisations to collect data on governance, at much higher levels of precision than other existing data sources. The second line of research focuses on the impacts of violence in two African countries. On the one hand, we study the impacts of political violence on social capital since 2012 in the case of the Malian conflict. The increased association participation in areas exposed to violent events cannot be considered as positive. Indeed, it is observed solely for family and political associations, which are comparatively inward-looking and act as interest groups. We interpret this finding as a form of withdrawal behind group or community boundaries which may exacerbate ethnic divisions and deepen the conflict. On the other hand, I study how workers of the informal labour market cope with criminal violence in Madagascar. Although victims of criminality seem not to adopt different behaviours on the labour market, the fear of crime impact productivity negatively, particularly in the agricultural sector. Fearful workers become more vulnerable to shock occurrence. Adults’ fear of criminal violence also channels to under 15 household members whose participation on the labour market increases

O primeiro objetivo da Tese consistiu na identificação e caracterização dos instrumentos de aferição epidemiológicos que vêm sendo propostos para a abordagem de IA domiciliar, bem como na síntese de suas propriedades psicométricas. Para tal, realizou-se busca sistemática em três bases de dados eletrônicas: MEDLINE, LILACS e SciELO. Não houve delimitação do período de publicação. Os resultados são apresentados no artigo intitulado Household food insecurity: a systematic review of the measuring instruments used in epidemiological studies. Foram identificados 24 instrumentos, todos breves e de fácil aplicação. A maioria foi desenvolvida nos Estados Unidos. O instrumento HFSSM apresentou o maior número de estudos de utilização e psicométricos, podendo ser recomendado sem hesitação. O segundo e principal objetivo desta Tese foi avaliar se a ocorrência de violência psicológica e física entre parceiros íntimos pode ser considerada um fator de risco para a ocorrência de Insegurança Alimentar (IA) domiciliar. As informações que subjazem a pesquisa originaram-se de um inquérito domiciliar realizado no Distrito de Campos Elíseos, Município de Duque de Caxias, entre abril a novembro de 2010. A população de estudo foi selecionada por meio de amostragem por conglomerados em três estágios (setor censitário, domicílio, indivíduo) com técnicas de amostragem inversa para a seleção dos domicílios. A amostra do estudo incluiu 849 mulheres que no período da entrevista relataram possuir algum relacionamento amoroso nos 12 meses anteriores. As informações foram obtidas por meio de entrevista utilizando-se um questionário estruturado, contendo instrumentos previamente validados, como a Revised Conflict Tatics Scales (CTS2) para a mensuração das violências e a Escala Brasileira de Insegurança Alimentar (EBIA) para a IA domiciliar. Utilizou-se a análise de caminhos (Path Analysis) na análise de dados o que permitiu explorar as relações entre as violências, entre estas e o Transtorno Mental Comum (TMC), este último e a IA, bem como as relações mais distais do modelo teórico. Os resultados são apresentados no artigo intitulado Violência entre parceiros íntimos, transtornos mentais comuns e insegurança alimentar: modelagem de equações estruturais. A hipótese central deste estudo foi corroborada, na medida em que tanto a violência psicológica, como a violência física se mostraram importantes fatores de risco para a IA, via a ocorrência de TMC. Contrariamente ao esperado, notou-se um maior efeito da violência psicológica do que da violência física na ocorrência do desfecho. Espera-se que a divulgação dos resultados desta Tese auxilie os profissionais e gestores na área de segurança alimentar e nutricional, bem como pesquisadores da área na tomada de decisões em relação ao instrumento de aferição a ser utilizado para a caracterização das situações e ampliem o olhar sobre o problema, incorporando outros fatores de risco, tais como as violências entre parceiros íntimos, aqueles estritamente econômicos, habitualmente considerados no debate sobre os determinantes e estratégias de enfrentamento da IA.
The first goal of the Thesis that consisted of identifying and characterizing the epidemiological measurement instruments that have been proposed for addressing HFI and synthesis of its psychometric properties. To this end, we performed a systematic search of three electronic databases: MEDLINE, LILACS and SciELO. There was no definition of the publication period. The results are presented in the article entitled "Household food insecurity: a systematic review of the measuring instruments used in epidemiological studies". Twenty-four instruments were identified; all brief and of easy application. The majority were devised in the United States. The HFSSM instrument had the largest number of use studies and psychometric and can be recommended without hesitation. The second and main objective of this Thesis was to evaluate the occurrence of physical intimate partner violence (IPV) of psychological type and can be considered a risk factor for the occurrence of household food insecurity (HFI). The information underlying the research originated from a household survey conducted in the District of Campos Elíseos, in the city of Duque de Caxias, between April and November 2010. The study population was selected using cluster sampling in three stages (census tract, household, individual) with inverse sampling techniques to the selection of households. The study sample included 849 women (82.03% of the interviews for the study background) than during the interview reported having a romantic relationship in the last 12 months. Information was obtained through interviews using a structured questionnaire containing previously validated instruments such as the Revised Conflict Tactics Scales (CTS2) to measure the IPV and Brazilian Food Insecurity Scale (EBIA) for HFI. The results are presented in the article titled "Intimate partner violence, common mental disorders and food insecurity: a survey- based structural equation modeling analysis". The central hypothesis of this study was corroborated, and IPV psychological presented both as direct kick in the occurrence of HFI effect, while the physical type of IPV only had indirect effect via CMD . It is hoped that the dissemination of the results of this thesis assists professionals and managers in the area of food security as well as researchers in the field in making decisions regarding the measurement instrument to be used for the characterization of situations and broaden the look about the problem, incorporating other risk factors such as intimate partner violence, strictly economic ones usually considered in the debate on the determinants and coping strategies of food insecurity.

Abstract:
This paper is an investigation of the determinants of household recycling behaviour in South Africa. Waste generation around the world is growing exponentially. The proportion of South African households who recycle is very low and landfilling is the primary method of waste disposal. This is problematic because landfilling has a negative impact on the environment and human health. Therefore, alternatives to landfilling, like recycling are necessary. Thus, it is important to understand what determines recycling behaviour. A probit regression analysis was carried out using data from the 2018 General Household Survey in order to understand household recycling behaviour. The results of the regression suggest that age, race, province, urban-rural residence, the presence of a radio in the household, and owning a vehicle are significantly correlated with household recycling behaviour (p<.10). Additionally, gender, marital status and household income are also significantly correlated with household recycling behaviour. However, the relationship is weaker (p<.10). Surprisingly, education, employment, dwelling-type, tenure and the presence of a school child in the household have no effect on recycling participation. These results can help policy-makers understand what factors influence recycling behaviour and help them develop and implement effective policies that optimise recycling activity.
