Abstract:
This thesis is a comparative study of optimal design-based univariate stratification as applied to highly skewed populations such as those observed in business and agricultural surveys. Optimal stratification is a widely used method for reducing the variance or cost of estimates, and this work considers various optimal stratification algorithms, and in particular optimal boundary algorithms, to support this objective. We first provide a background to the theory of stratification and stratified random sampling, and extend this through the derivation of optimal allocation strategies. We then examine the effect of allocation strategies on the variance and design effect of estimators, and in particular find several issues in applying optimal or Neyman allocation when there is little correlation between the survey population and auxiliary information. We present a derivation of the intractable equations for the construction of optimal stratum boundaries, based on the work of Dalenius (1950), and derive the cumulative square root of frequency approximation of Dalenius & Hodges (1957). We then note a number of issues within the implementation of the cumulative square root of frequency rule surrounding the construction of initial intervals, and find that the placement of boundaries and the variance of estimates can be affected by the number of initial intervals. This then leads us to propose two new extensions to the cumulative square root of frequency algorithm, using linear and spline interpolation, and we find that these result in some improvements in the results for this algorithm. We also present a complete derivation of the Ekman algorithm, and consider the extended approach of Hedlin (2000). We derive several new results relating to the Ekman algorithm, and propose a new kernel density based algorithm. We find all three Ekman based algorithms produce similar results for larger populations, and provide some recommendations on the use of these algorithms depending on the size of the population. We look at the derivation and implementation of the Lavallee-Hidiroglou algorithm, and find that it is often slow to converge or does not converge for Neyman allocation. We therefore adopt a random search model of Kozak (2004), and note that the Lavallee-Hidiroglou algorithm generally produces superior results across all populations used in this thesis. We briefly investigate the optimal number of strata by examining the work of Cochran (1977) and Kozak (2006), and find that there is a diminishing marginal effect from increasing the number of strata and possibly some benefit from constructing more than six strata. However we also acknowledge that the cost of constructing such strata may offset any potential gain in precision from constructing more than five or six strata. Finally we consider the how many of these problems can be developed further, and ultimately find that such problems for deciding the number of strata, construction of stratum boundaries, and the allocation of sample units among the strata may require an approach that takes account of the relationship between the auxiliary variable and the survey information. We therefore suggest investigating these algorithms further within the context of a model-assisted environment in order to help account for the relationship between the auxiliary information and survey population.

Abstract:
Although the primary role of the computer has been in processing and analysis of survey data, it has increasingly been used in data collection. Computer surveys are not exempt from a common problem: some refuse to participate. Many researchers and practitioners indicate the refusal problem is less for computer surveys, perhaps due to the novelty of the method. What has not been investigated is the refusal problem when on-line surveys are no longer novel. This research study examines the use of one form of computer-assisted data collection, the electronic or on-line survey, as an organizational research tool. The study utilized historical response data and administered an on-line survey to individuals known to be cooperative or uncooperative in other on-line surveys. It investigated nonresponse bias and response effects of typical responders, periodic participants, and typical refusers within a sample of corporate employees in a computer-interactive interviewing environment utilizing on-line surveys. The items measured included: participation, respondent characteristics, response speed, interview length, perceived versus actual interview length, quantity of data, item nonresponse, item response bias, consistency of response, extremity of response, and early and late response. It also evaluated factors reported as important when deciding to participate, preferred data collection method, and preferred time of display. Past participation, attitudes toward on-line organizational surveys, response burden, and response error were assessed. The overall completion rate of 55.7% was achieved in this study. All effort was made to encourage cooperation of all groups, including an invitation to participate, token, on-line pre-notification, 800 number support, two on-line reminders, support of temporary exit, and a paper follow-up survey. A significant difference in the participation of the three groups was found. Only three demographic variables were found to be significant. No significant differences were found in speed of response, interview length, quantity, item nonresponse, item response bias, consistency, and extremity. Significant differences were found in the perceived and actual times to complete the survey.

Abstract:
This thesis describes the design, maintenance and statistical analysis involved in undertaking a Longitudinal Survey. A longitudinal survey (or study) obtains observations or responses from individuals over several times over a defined period. This enables the direct study of changes in an individual's response over time. In particular, it distinguishes an individual's change over time from the baseline differences among individuals within the initial panel (or cohort). This is not possible in a cross-sectional study. As such, longitudinal surveys give correlated responses within individuals. Longitudinal studies therefore require different considerations for sample design and selection and analysis from standard cross-sectional studies. This thesis looks at the methodology for analysing social surveys. Most social surveys comprise of variables described as categorical variables. This thesis outlines the process of sample design and selection, interviewing and analysis for a longitudinal study. Emphasis is given to categorical response data typical of a survey. Included in this thesis are examples relating to the Goodna Longitudinal Survey and the Longitudinal Survey of Immigrants to Australia (LSIA). Analysis in this thesis also utilises data collected from these surveys. The Goodna Longitudinal Survey was conducted by the Queensland Office of Economic and Statistical Research (a portfolio office within Queensland Treasury) and began in 2002. It ran for two years whereby two waves of responses were collected.

Abstract:
The study utilized the covariance structure comparison methodology - Multigroup Analysis in Structural Equation Modeling - evaluating measurement equivalence of English and Spanish versions of an employee opinion survey. The concept of measurement equivalence was defined as consisting of four components: sample equivalence, semantic equivalence, conceptual equivalence and scalar equivalence. The results revealed that the two language versions of the survey exhibited acceptable measurement equivalence across five survey dimensions Communications, Supervision, Leadership, Job Content & Satisfaction and Company Image & Commitment. Contrary to the study second hypothesis, there was no meaningful difference in opinion scores between English-speaking and Spanish-speaking respondents on the latent construct of Job Content & Satisfaction.

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:
Relatively little is known about marine controlled-source electromagnetic surveys (MCSEM) used to detect hydrocarbon reservoirs. Typical MCSEM require the use of inversion to generate a model of the subsurface. We utilize a 3D finite-element forward model to simulate a MCSEM survey. With the results we were able to determine the strengths and weaknesses of each transmitter and receiver configuration that would best detect a shallow hydrocarbon target. Careful selection of the correct configuration is important as we have found that incorrect transmitter orientation, offset and receiver measurement component can yield misleading results. Using the ideal configuration we were able to directly image the hydrocarbon target without the use of inversion modeling. The direct image is able to show the hydrocarbon target's shape and edges without any ambiguity. The direct image of the target can potentially be used to refine 3D inversion modeling, or be used in conjunction with seismic profiles to refine seismic picks.

Full text
Abstract:
Web access panels are self selected panels constructed with the aim of drawing inference for general populations, including large segments of the population who rarely or never access the Internet. A common approach for modeling survey data collected over access panels is combing it with data collected by a randomly selected reference survey sample from the target population of Interest. The act of joining the panel is then treated as a random process where each member of the population has a positive probability of participating in the survey. The combined reference and panel survey sample can then be used for different estimation approaches which model either the selection process or the measurement of interest, or some case the two together. Most practitioners and academics who have considered this combined sample approach, model the selection process by a single phase process from the target population directly to the observed sample set. In the following work, I assume selection into the panel is a sequential rather than a single phase process and offer several estimators that are underlined by appropriate sequential models. After a careful investigation of a variety of single phase methods applied in practice, I demonstrate the benefits a sequential framework has to the panel problem. One notable strength of this approach is that by assuming a sequential framework the modeler can include important variables associated with Internet and Web usage. Under a single phase model inclusion of such information would invalidate basic assumptions such as independence between selection and model covariates. In this work I also suggest a carefully structured panel estimation strategy, combining a sample selection design with chosen estimator. Under the sequential framework I demonstrate the potential of combining a within-panel random sampling procedure, that is balanced on a sequence of target statistics, with estimators that are modeled over both the selection process and the variable of interest. I show that this strategy has several robustness properties over and beyond currently applied estimators. I conclude by describing an estimation algorithm which applies this estimation strategy to the combined panel and reference survey sample case.

Full text
Abstract:
As researchers increasingly use web-based surveys, the ease of dropping out in the online setting is a growing issue in ensuring data quality. One theory is that dropout or attrition occurs in phases that can be generalized to phases of high dropout and phases of stable use. In order to detect these phases, several methods are explored. First, existing methods and user-specified thresholds are applied to survey data where significant changes in the dropout rate between two questions is interpreted as the start or end of a high dropout phase. Next, survey dropout is considered as a time-to-event outcome and tests within change-point hazard models are introduced. Performance of these change-point hazard models is compared. Finally, all methods are applied to survey data on patient cancer screening preferences, testing the null hypothesis of no phases of attrition (no change-points) against the alternative hypothesis that distinct attrition phases exist (at least one change-point).

Abstract:
Car dependency which corresponds to excessive and inappropriate usage of the car itself is becoming a major problem all around the world. It shapes urban areas in such a way that the overall urban form as well as individual activities all develop to accommodate cars. However, introducing nonmotorized modes is seen as a remedy to overcome the car dependency. It offers a chance for retrieving healthy urban environments and healthy social lives and also for revitalizing/enhancing public spaces in cities. This means increasing the quality and quantity of pedestrian areas which have been receiving increasing emphasis all around the world. In this thesis, it is intended to show that pedestrianization can be, and should be, a valid transport policy in growing metropolitan areas that are becoming more and more car-oriented, such as Ankara. As a case study, this study assesses potentials and possibilities for creating a pedestrian environment in Ankara, Tunali Hilmi Street. To do so, detailed pedestrian surveys/analyses including v pedestrian counts, pedestrian movement analysis, pedestrian static analysis and pedestrian space analysis throughout the street and questionnaires with potential stakeholders including pedestrians, shop-owners and taxi-drivers are carried out. Through these analyses, it is assessed whether Tunali Hilmi Street is suitable for such an arrangement in terms of pedestrianization or not. As a result, this thesis makes an emphasis on non-motorization and pedestrianization as a method of preventing increasing car-oriented arrangements and revitalizing city centre for the case of Tunali Hilmi Street.

>Magister Scientiae - MSc
In the standard (‘concordance’) model of Cosmology, there is a fundamental assumption that the Universe is statistically isotropic and homogeneous on large scales, known as the Cosmological Principle. The Cosmological Principle requires that the dipole anisotropy apparent in the CMB should also be observed in galaxy number counts if this signal occurs due to the aberration and Doppler effects from our peculiar motion. This thesis will investigate the accuracy with which the cosmic kinematic dipole can be determined by comparing real data from NRAO VLA Sky Survey (NVSS) catalog with the simulated sky maps following its specifications. The mock maps are generated using FLASK code which assumes a lognormal distribution for the radio count density field from z=0 to z =4 and taking as an entry an angular power spectrum from CAMB which assumed a flat ΛCDM cosmology and a redshift distribution. After analising the kinematic dipole, we turn to the analysis of statistical isotropy in the catalog. We used ANalysis Of Variance (ANOVA) test on patches in the sky of different radii as one of the statistical tools for the analysis. We found that as we go to a higher radius for the patches, we have a better agreement between the theory and the observation as expected. We also saw that the more we are rigorous on the rejection criteria, the smaller is the discrepancy between the observed and simulated number count distribution in the sky. We found an optimum choice of 25◦ as patch size, and if the accepted patches have a maximum of 30% of their pixels masked. Therefore, we find that the NVSS data agrees with the fundamental assumption of statistical isotropy at angular scales > 20◦.

Abstract:
An assessment of a software engineering program has been carried out by reviewing state-of-the-art literature pertaining to software engineering education. Six surveys have been adopted and the result implies that the balance of the curriculum should be revised, and that software engineering education ought to expand the technical oriented knowledge areas somewhat. Relevant curriculum data have been derived hereby, which also confirms other studies in the area. This data, along with a benchmark of the software engineering program to the Software Engineering Body of Knowledge (SWEBOK), is very constructive to universities as it assists educators, trainers, and software engineering practitioners in evaluating, designing, and recommending existing and proposed curricula.

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:
This thesis investigates some of the primary institutional challenges linked to the management and reporting of student satisfaction and examines how institutions use, and manage, the business intelligence arising out of student satisfaction surveys. It investigates the effectiveness of setting institutional strategies aimed at improving the student experience and, in its detail, the study assesses the extent to which principal survey instruments, primarily the National Student Survey (NSS), accurately capture the views of students. The research endeavours to undertake a critical review of the NSS enabling the thesis, based on a case study organisation, to serve as a robust tool to guide the setting of strategy aimed at improving the student experience. It investigates the extent to which the NSS accurately capture the views of the students surveyed and whether this is represented in the recorded level of satisfaction. It also looks at key stakeholders within the organisation and their understanding and reaction to the NSS process and its principal outputs. The thesis concludes that, although the NSS does capture views of students insofar as students complete the questionnaire, the survey fails at a basic level due to a number of factors. The thesis challenges the validity of the results of the survey, the conclusions drawn from the survey, and the meaning placed on them. Key stakeholders, within the case study organisation, do not fully understand and react to either the NSS process or its principal outputs and this is compounded by the students’ approach to the survey. Local institutional surveys have the potential to provide a rich source of data to complement the NSS but are not used to their full potential so represent both positive and negative responses to the limitations of the NSS. Finally, the thesis makes a number of recommendations to Universities and those academics and administrators, in charge of the strategy, management, and implementation of the annual NSS and local institutional surveys.

Abstract:
Survey propagation (SP) has recently been discovered as an efficient algorithm in solving classes of hard constraint-satisfaction problems (CSP). Powerful as it is, SP is still a heuristic algorithm, and further understanding its algorithmic nature, improving its effectiveness and extending its applicability are highly desirable. Prior to the work in this thesis, Maneva et al. introduced a Markov Random Field (MRF) formalism for k-SAT problems, on which SP may be viewed as a special case of the well-known belief propagation (BP) algorithm. This result had sometimes been interpreted to an understanding that “SP is BP” and allows a rigorous extension of SP to a “weighted” version, or a family of algorithms, for k-SAT problems. SP has also been generalized, in a non-weighted fashion, for solving non-binary CSPs. Such generalization is however presented using statistical physics language and somewhat difficult to access by more general audience. This thesis generalizes SP both in terms of its applicability to non-binary problems and in terms of introducing “weights” and extending SP to a family of algorithms. Under a generic formulation of CSPs, we first present an understanding of non-weighted SP for arbitrary CSPs in terms of “probabilistic token passing” (PTP). We then show that this probabilistic interpretation of non-weighted SP makes it naturally generalizable to a weighted version, which we call weighted PTP. Another main contribution of this thesis is a disproof of the folk belief that “SP is BP”. We show that the fact that SP is a special case of BP for k-SAT problems is rather incidental. For more general CSPs, SP and generalized SP do not reduce from BP. We also established the conditions under which generalized SP may reduce as special cases of BP. To explore the benefit of generalizing SP to a wide family and for arbitrary, particularly non-binary, problems, we devised a simple weighted PTP based algorithm for solving 3-COL problems. Experimental results, compared against an existing non-weighted SP based algorithm, reveal the potential performance gain that generalized SP may bring.

Abstract:
Likelihoods are widely used in the estimation of parameters, but the computation of their maximum can be quite complicated, and sometimes impossible in the presence of nuisance parameters. In such cases we seek a modified likelihood that will allow us to make inference on the parameters of interest with as little loss of information as possible. In the present work we will investigate some of these modified likelihoods, namely marginal likelihoods, conditional likelihoods, profile likelihoods, partial likelihoods, empirical likelihoods, and functions that exhibit properties similar to the ones of the likelihoods, more precisely the quasi-likelihoods. We will point out some cases where these modified likelihoods give rise to satisfactory estimations, and some other cases where they fail to give satisfactory estimations.

Four surveys of users of the AskERIC email reference service were conducted, during the years 1998, 2000, 2001, and 2002. These surveys presented a snapshot of the AskERIC user population and user satisfaction at a single point in time. This paper reanalyzes the findings from these surveys utilizing repeated survey techniques. This paper presents the evolution of some of the demographics of AskERICâ s user population over time, as well as the evolution of AskERIC user behavior. As perhaps the oldest AskA service in existence, this analysis of AskERIC data sheds light on the evolution of all AskA services, and of email-based reference services in general.

Abstract:

This paper utilizes survey data to compare several non-survey methods of modeling the economic impacts of biofuels plants. It examines differences in the input coefficients derived from the survey versus the trade coefficients generated through the non-survey methods. It finds that of the three non-survey methods examined, the Swenson (2006) scenario input coefficients most closely represent those found in the survey based on the performance of the non-survey scenario input coefficients in a variety of statistical tests. Further, it examines the economic impacts (multipliers) generated by these scenarios compared to those generated from the survey. Based upon statistical tests of the multipliers, the Swenson scenario’s estimated impacts most closely represent the impacts derived from the survey.

Abstract:
We present the rationale for and the observational description of ASPECS: the ALMA SPECtroscopic Survey in the Hubble Ultra-Deep Field (UDF), the cosmological deep field that has the deepest multi-wavelength data available. Our overarching goal is to obtain an unbiased census of molecular gas and dust continuum emission in high-redshift (z > 0.5) galaxies. The similar to 1' region covered within the UDF was chosen to overlap with the deepest available imaging from the Hubble Space Telescope. Our ALMA observations consist of full frequency scans in band. 3 (84-115 GHz) and band. 6 (212-272 GHz) at approximately uniform line sensitivity (L'(CO) similar to 2 x 10(9) K km s(-1) pc(2)), and continuum noise levels of 3.8 mu Jy beam(-1) and 12.7 ae Jy beam(-1), respectively. The molecular surveys cover the different rotational transitions of the CO molecule, leading to essentially full redshift coverage. The [C II] emission line is also covered at redshifts 6.0 < z < 8.0. We present a customized algorithm to identify line candidates in the molecular line scans. and quantify our ability to recover artificial sources from our data. Based on whether multiple CO lines are detected, and whether optical spectroscopic redshifts as well as optical counterparts exist, we constrain the most likely line identification. We report 10 (11) CO line candidates in the 3mm (1mm) band, and our statistical analysis shows that < 4 of these (in each band) are likely spurious. Less than one-third. of the total CO flux in the low-J CO line candidates are from sources that are not associated with an optical/NIR counterpart. We also present continuum maps of both the band. 3 and band. 6 observations. The data presented here form the basis of a number of dedicated studies that are presented in subsequent papers.

Abstract:
Diabetes is a significant health problem in Mexico and one of the leading causes of death. Studies in other countries have suggested that socioeconomic status (SES) contributes to the development of type 2 diabetes. However, only few studies in Mexico have dealt with SES differentials in diabetes. The aim of this thesis is to examine the association between SES and type 2 diabetes among Mexican adults aged 20-69. In contrast with previous studies, we use individual, household and municipality measures of SES simultaneously when investigating: prevalence of total, diagnosed and undiagnosed diabetes in the year 2000; and incidence of diagnosed diabetes during the period 2002-2005. Furthermore, we explore the effects of diabetes on employment status, and changes in waist circumference (WC) among adults with diabetes. Data were used from the 2000 National Health Survey (NHS-2000) and the Mexican Family Life Surveys 2002 and 2005 (MxFLS-2002 and MxFLS-2005). Diabetes was defined using self-reports (in both surveys) and outcomes from capillary blood tests (only in the NHS). SES was measured through educational attainment, household income, household wealth and municipality deprivation. The index of household wealth was calculated and evaluated using the National Survey of Household Income and Expenditure (ENIGH-2000). The Human Development Index (HDI) and the Deprivation Index (DI) at the municipality level are official statistics obtained from the 2000 Mexican Census of population. Two level logistic regression models were estimated, and the analyses were stratified mainly by sex, urban/rural stratum and municipality deprivation. Our findings confirm an association between socioeconomic status and diabetes. However, this relationship varies by SES measure, sex, urbanisation and deprivation. A consistent result was that diabetes was more common among the less educated, in the least deprived municipalities, and in urbanised localities. Variations in diabetes between municipalities were better explained by genetic, biological and lifestyle factors, than by SES. Diabetes was associated with working status, but not with employment status or changes in WC. Increases in urbanisation and further socioeconomic development, in combination with increased life expectancy, will lead to a higher prevalence of diabetes particularly among the most vulnerable groups. In addition to the promotion of healthy behaviours in the overall Mexican population, health sustainability should be prioritized in those communities at early stages of the nutritional and epidemiological transition.

Abstract:
Chapter 1: The Impact of Culture on the Second-Generation Immigrants’ Level of Trust in Canada Trust is one of the main elements of social capital; it determines the extent to which an individual cooperates with others. In this chapter, I assess whether cultural factors influence the level of trust in the population of second-generation immigrants in Canada. This paper is related to two strands of empirical literature. The first analyses the determinants of trust and the second studies the cultural transmission of values, attitudes and beliefs. I follow closely the literature on the cultural transmission and use an epidemiological approach to assess whether trust of second-generation immigrants is affected by their cultural heritage. This approach consists of comparing information about the outcomes of second-generation immigrants with that of the country of origin of their ancestry. We apply this approach using the Ethnic Diversity Survey (EDS), the World Value Survey (WVS) and the European Value Survey (EVS). Estimation results show that the average level of trust in the countries of origin of the ancestors of the second-generation immigrants has a strong significant impact on their level of trust. Thus, individual whose country of ancestry displays a high level of trust, tend to have a high level of trust. This provides evidence that individuals’ level of trust is not only explained by their personal experiences, characteristics, and the environment in which they live; but also by the culture in their country of ancestry. This means that culture does matter! I find that the results remain robust even if certain key countries are omitted or a different data set is used. Chapter 2: Decomposing Health Achievement and Socioeconomic Health Inequalities in Presence of Multiple Categorical Information This chapter presents a decomposition of the health achievement and the socioeconomic health inequality indices by multiple categorical variables and by regions. I adopt Makdissi and Yazbeck's (2014) counting approach to deal with the ordinal nature of the data of the United States National Health Interview Survey 2010. The findings suggest that the attributes that contribute the most to the deviation from perfect health in the United States are: anxiety, depression and exhaustion. Also, I find that the attributes that contribute the most to the total socioeconomic health inequality are ambulation, depression and pain. The regional decomposition results suggest that, if the aversion to socioeconomic health inequality is high enough, socioeconomic health inequalities between regions are the main contributors to the total socioeconomic health inequality in the United States. Chapter 3: Accounting for Freedom and Economic Resources in the Assessment of Changes in Women Poverty in Sub-Saharan Africa This chapter assesses the importance of freedom in women’s wellbeing in twelve Sub-Saharan Africa countries by using data from Demographic Health Surveys. This paper presents a poverty comparison by using the stochastic dominance approach and relies on the economic resources and freedom as the two aspects of wellbeing which evokes the multidimensionality of poverty. This study is related to the following three pieces of literature: the sequential stochastic dominance, the multidimensional poverty, the Sen’s capability approach which is based on freedom. This paper is built on Makdissi et al. (2014) but differs from it in a number of respects. First, it focuses on poverty instead of welfare. Secondly, it applies the Shapley decomposition to determine the contributions of the economic resource distribution and the incidence of the threat of domestic violence to poverty changes over time. Consistent with previous work on the importance of freedom, I find that more freedom, i.e. less threat of domestic violence, affects women’s wellbeing positively since it decreases women’s poverty. The results indicate that women’s wellbeing has improved in Burkina Faso, Ghana, Kenya, Lesotho, Madagascar, Malawi, Rwanda, Senegal, and Zimbabwe and deteriorated in Ethiopia, Nigeria and Tanzania.

Abstract:
The beginning of X-ray astronomy is based on two accidental discoveries made in 1962. A single point source, Scorpio X-1 and remarkable discovery of the diffuse background radiation, three years before the microwave background was discovered. Over the past four decades, X-ray astronomy has matured into a major branch of astronomy, contributing to our understanding of the physical processes operating in many different types of sources, from stars to high redshift quasars. In 1990, the launch of the ROSAT satellite offered to unique opportunity to investigate the radio properties of X-ray emitters. A sample of faint X-ray emitters from a deep pointed observation is used in this thesis to investigate the prediction that sub-mJy radio source are a major contributor to the X-ray background. Another sample of 695 bright X-ray emitters were selected from ROSAT All Sky Survey for optical follow-up as a European Southern Observatory key project. The radio follow-up of the sample was undertaken for this thesis. The aim is to construct a catalogue of radio emitting X-ray (REX) sources to study their quantitative statistical properties and to select out a sample of BL-Lac objects for further study. Based on previous surveys approximately 19% or 130 of the X-ray sources should be directly associated with a radio emitter, of which 90% will be positionally coincident with the most plausible optical candidate for an X-ray source. This increases the efficiency of the optical identification program by about 15 percent.

Abstract:
Includes bibliographical references.
This thesis is based on the Edinburgh-Gape Blue Object Survey and includes a general review of blue star sky surveys, a detailed discussion of the selection techniques, the present status of the survey, and follow-up photometry and spectroscopy of the cataclysmic variable stars (GVs) found by the survey. Because of the north-south imbalance in the number of blue objects, the Edinburgh-Gape Blue Object survey was designed to discover previously unknown blue objects with B≤~18 at high galactic latitude in the southern hemisphere. At present, all the planned fields (61 fields) in the North Galactic Pole region and 26 fields in the South Galactic Pole regions are complete, covering 2488 square degrees. The preliminary results show that the survey has an internal completeness of ~94% for objects with U-B bluer than the cutoff --0.3, and selects objects with an accuracy in photographic U-B of 0.16 mag. UBV measurements and spectra have been obtained for ~2000 objects. Half of these objects are hot subdwarfs which comprise the sdO, sdB, and sdOB stars. The white dwarfs account for about 17% of the total. About 18% of the objects are horizontal branch B and normal B stars. Cataclysmic variable stars and quasars comprise only a small fraction, 2 and 6 percent, respectively. Less than one percent are galaxies. The remaining ~5% have unknown spectral classes at present. So far, 25 cataclysmic variable stars have been found by the survey. The space density was estimated to be 1.6xl0-⁶ pc-³. Among these cataclysmic variables, 6 dwarf novae and 8 nova-like variables are new discoveries; detailed study of their photometric and spectroscopic characteristics are discussed in Chapters 6-10. One of the stars discovered, a close binary with large reflection effect, is a predecessor of the cataclysmic variables. Napier's (1968) method for the reflection effect in close binaries was used to model the light curve in order to solve for the physical properties of the system. Photometry, spectroscopy, and model fits for this system are discussed in Chapter 5.
