Texto completoThis research estimated the value of the rate of deaths per kilometer traveled by the road vehicles fleet in Brazil and in each of the states of the federation, in the years 2004 to 2008. To determine the values of the average annual distance traveled by vehicles - parameter needed to estimate the rate of deaths per vehicle-kilometers - an appropriate methodology has been developed with reference on the amount of fuel sold by distributors in every state. The states were ranked according to all indexes associated with road fatalities, and the relationship between the rate of deaths per kilometer and the level of economic development of states, expressed by the motorization rate and the GDP per capita, is analyzed. It appears that the situation of traffic mortality is a serious national problem, especially in the poorest states, where the rate of deaths per vehicle-km reaches very high figures. The positive fact is that the numbers point to a continued reduction in the rate of deaths per kilometer, which decreased from 68.26 to 55.87 deaths per billion km in the country between 2004 and 2008 (a decrease of 18.15%). This is due to the increase on the distance traveled, a result of the increased fleet and economic growth, and also of some stabilization in the number of deaths; being the last a consequence of nationwide actions implemented by the federal government, and also of specific actions carried out in some states.

Pontos de contagem é um método atrativo para utilização em programas de monitoramento de aves por ser simples e permitir que vários locais sejam amostrados. Contudo, nos estudos realizados em regiões tropicais utilizando-se deste método, os autores utilizam a variável "tempo" de forma diferente para registrar a abundância das aves nos fragmentos florestais. Portanto, os dados obtidos por estes diferentes estudos não podem ser comparados entre si, pois o tempo gasto nos pontos e o tempo total das contagens diferem significativamente, assim como as distâncias percorridas. Desta forma, o objetivo do presente trabalho foi o de comparar quatro durações de tempos distintas (5, 10, 15 e 20 minutos) para identificar qual destas registra maior riqueza e abundância de aves em fragmentos de florestas tropicais. As amostragens foram realizadas durante 12 meses em um fragmento de floresta estacional semidecidual de 2.180 ha no interior de São Paulo. Um total de 120 minutos de amostragem foi realizado a cada mês para cada tempo distinto, o que exigiu um número diferente de pontos amostrais e uma diferente distância total percorrida na floresta. Com relação à riqueza e abundância, os testes estatísticos evidenciaram que o tempo de cinco minutos apresentou resultados que diferem significativamente dos outros tempos (10’, 15’ e 20’). Além disso, houve uma correlação positiva entre as diferentes distâncias percorridas e a abundância registrada, ou seja, quanto maior a distância percorrida, maior a riqueza e abundância registradas. Um aspecto da ecologia da comunidade que deve ser levado em consideração é que as espécies são distribuídas de forma heterogênea em uma floresta, pois diferentes espécies de plantas e diferentes padrões na fisionomia da floresta proporcionam diferentes tipos de micro-hábitats para aves. Quando se utiliza um maior número de pontos de amostragem, espera-se encontrar uma maior heterogeneidade da floresta, portanto, a maior riqueza registrada pela contagem de cinco minutos está associada a um maior número de pontos necessários para isolar a variável tempo. Outro fator importante é a variação encontrada nos valores do Índice Pontual de Abundância amostrados. A menor variação e consequente maior poder estatístico ocorreu na contagem mais curta (5’ minutos), indicando que o tempo é o mais eficiente para atingir os objetivos propostos. É importante ressaltar que este período de tempo exigiu quatro meses a menos para registrar o mesmo número de espécies que as outras contagens. No oitavo mês de amostragem, o tempo de cinco minutos já acumulava 119 espécies, valor maior que a riqueza total obtida com os outros tempos. Portanto, ao utilizar o método de pontos de contagem para analisar a estrutura da comunidade de aves em fragmentos florestais, o melhor resultado foi alcançado com a contagem de cinco minutos. Este tempo provou ser mais eficiente por detectar maior riqueza e abundância com menor esforço amostral, além de aumentar a chance de se registrar novas espécies devido ao maior número de pontos realizados em um maior número de micro-hábitats na floresta.
Point counts are attractive for use in avian monitoring programs because they are straightforward and allow numerous geographic sites to be sampled. However, in studies conducted with the point count method in tropical regions, authors use the variable "time" differently to record the abundance of birds in forest remnants. Therefore, the data obtained by different studies cannot be compared since the time spent at the points and the total counting time differ significantly, as do the distances traveled. The objective of the present study was to compare four distinct point count times (5, 10, 15 and 20 minutes) to identify which registers relatively greater bird richness and abundance in tropical forest fragments. Samplings were carried out for 12 months in a 2,180 ha fragment of semideciduous forest in the interior of the state of São Paulo. A total of 120 minutes of sampling was carried out each month for each counting time, which required a different number of counting points and a different total distance traveled in the forest. With respect to richness and abundance, the statistical tests showed that five minutes of counting yielded results that were significantly different from those of the other point count times. Additionally, there was a positive correlation between the different distances traveled and the recorded abundance, i.e., the greater the distance traveled, the greater the richness and abundance. One aspect of community ecology that must be considered is that species are distributed heterogeneously in a continuous forest because different plant species and different patterns in the terrain of the forest provide different microhabitats for birds. When a greater number of sampling points is used, greater forest heterogeneity is expected; therefore, the greater richness recorded by the five-minute counts is associated with a greater number of points needed to isolate the time variable. Another important factor is the variation in the sampling rates; the lowest variation, and consequently greater statistical power, occurred in the shortest count (5′), indicating that this counting time is effective for meeting the proposed objectives. Importantly, this counting time required four fewer months to record the same number of species as the other times. By the eighth month of sampling, the five-minute count had accumulated 119 species, which was higher than the total richness obtained with the other times. Therefore, when using the point method to analyze the community structure of birds in forest fragments, the best result was achieved with the five-minute count. This time proved to be more efficient because it detected greater richness and abundance with a lower sampling effort and increased the chance of registering new species due to the higher number of sampling points over a larger number of microhabitats in the forest.

Texto completoRoad traffic contributes significantly to atmospheric emissions in urban areas, a major issue in the fight against climate change. Therefore, joint monitoring of road traffic and related emissions is essential for urban public decision-making. And beyond this kind of procedure, public authorities need methods for evaluating transport policies according to environmental criteria.Coupling traffic models with traffic-related emission models is a suitable response to this need. However, integrating this solution into decision support tools requires a refined and dynamic char-acterization of urban mobility. Cell phone data, particularly Call Detail Records, are an interesting alternative to traditional data to estimate this mobility. They are rich, massive, and available worldwide. However, their use in literature for systematic traffic characterization has remained limited. It is due to low spatial resolution and temporal sampling rates sensitive to communication behaviors.This Ph.D. thesis investigates the estimation of traffic variables necessary for calculating air emis-sions (total distances traveled and average traffic speeds) from such data, despite their biases. The first significant contribution is to articulate methods of classification of individuals with two distinct approaches of mobility reconstruction. A second contribution is developing a method for estimating traffic speeds based on the fusion of large amounts of travel data. Finally, we present a complete methodological process of modeling and data processing. It relates the methods proposed in this thesis coherently

This thesis documents the design process of a new type of inline skate intended to be a viable form of transportation over short distances. Current inline skates are optimized for transportation over long distances but are not useful for travel over short distances because of the time required to put them on and the fact that they are cumbersome to carry. Through a survey and various prototypes, key characteristics have been identified that would make inline skates worth using for short commutes. Characteristics identified include the ability to fit over various types of footwear, the ability to put on at take off the skate quickly and the fold the skates for easy storage when not in use. A working prototype has been developed to demonstrate and verify the first two of these three characteristics. Users tested this prototype and provided feedback.

Texto completoThe United States (US) witnessed remarkable growth in annual long distance travel over the past few decades. Over half of the long distance travel in the US is made for pleasure, including visiting friends and relatives (VFR) and leisure activities. This trend could continue with increased use of information and communication technologies for socialization, and enhanced mobility being achieved using fuel-efficient (electric/hybrid) and technology enhanced vehicles. Despite these developments, and recent interest to implement alternate mass transit options to serve this market, not much exists on the measurement, analysis and modeling of long distance pleasure travel in the U.S.
Statewide and national models are used to estimate long distance travel, but these are predominantly trip-based models, making it difficult to understand long distance trips as collection of household-level travel behavior. This form of travel behavior has been studied a lot in tourism, but in a piecemeal manner, such as to (from) a specific destination. Further, most of these studies are confined to analyzing leisure market, with VFR market gaining recognition only recently. In essence, annual household long distance pleasure travel behavior needs to be studied in a comprehensive manner rather than as isolated trips. This is because, most of these household travel decisions are undertaken considering their annual time and monetary budget, and their perceived cost to travel to one (or more) destination for given pleasure purpose on one (or more) occasion using a given mode of travel. Thus, the main objective of this dissertation is to develop a comprehensive behavioral model framework to analyze the above-discussed annual household long distance pleasure travel choices.
To start the above effort, it is first required to collect detailed annual household travel data, last collected over two decades ago (e.g.: ATS, 1995). No such recent effort has been pursued due to the significant labor and economic resource required to undertake it. There exist recent surveys (NHTS, 2001), but collected over a shorter (four week) period, and require significant processing even to arrive at aggregate annual travel estimates. Second, besides surveys, there is a need for additional data to estimate households’ annual pleasure travel budget, and their cost to travel and stay at each of their potential destination choices, which are not readily available.
Thus, as the first goal, this dissertation analyzes long distance travel reported across historical surveys (NPTS; ATS; NHTS), to understand the differences in their definition, enumeration of purpose and collection methods. The intent here is twofold, first to conceive a method to estimate annual travel from surveys with shorter collection period. Further, the second intent is to gather travel patterns from these historical datasets such that it informs the second goal of this dissertation, i.e. development of a behavioral framework to analyze annual household pleasure travel. To this effect, this research also analyzes pleasure expenditures using Consumer Expenditure Survey (CEX, BLS) data. Interestingly, the analysis reveals CEX pleasure travel expenditure pattern to be similar to the travel pattern reported for the same market segments in travel survey (ATS).
Importantly, the above analysis informs the development of behavioral models, pursued as two distinct tasks to achieve the second goal. As the first task, a novel econometric model and forecasting procedure is developed to analyze a household’s annual long distance leisure travel decisions. Specifically, a households’ time spent across one (or more) destination and travel mode to such destination for leisure is modeled subject to time and money budget constraints. In this methodological framework, the destination choice is modeled as a continuous variable (time at destination) using Multiple-Discrete Continuous Extreme Value model (MDCEV). While, travel mode choice to these destination(s) are modeled as a discrete choice, through a nested Multinomial Logit Model (MNL), with price variation introduced across the above choice of destination(s) and travel modes (air/ground). This required estimating annual monetary budgets, travel cost and per night lodging cost for each sample household, with each of them having 210 potential destinations and 2 travel mode choices respectively.
The second task, involved the development of a broader national model system to analyze households’ annual pleasure travel decisions such as: choice (duration) at destination(s), travel purpose (VFR or leisure), mode (airplane or auto) choice and trip frequencies to these destination(s) using the same dataset. It was modeled in two stages, with the first stage estimating households’ annual pleasure time budget using a stochastic frontier model. This budget was then used as constraint to analyze households’ annual choice of destination and purpose using a nested MDCEV-MNL model in the second stage. A log sum variable from a nested joint multinomial logit model of trip frequency and mode choice for each purpose (VFR or leisure) is also introduced as input at this stage. This model was then validated using a prediction procedure, and further applied to test a policy scenario (increase in travel cost). The above national pleasure travel demand model could be further enhanced by including monetary constraints and price variation as in the first task. Overall, the model system proposed in this dissertation forms the foundation for a national comprehensive long distance travel model. This could be achieved through inclusion of other prominent travel purpose such as business and commuting to the national travel demand model presented in this research.

Texto completoENGLISH ABSTRACT: Order picking is the most important activity in distribution centres. It involves the process of retrieving products from storage in response to a speci c customer request. The order picking system in a distribution centre used by Pep Stores Ltd. (Pep), located in Durban, South Africa, is considered. The order picking system in Pep utilises picking lines. The system requires that the pickers move in a clockwise direction around the picking line. The planning of picking lines may be divided into three tiers of decisions. The rst tier determines which Stock Keeping Units (SKUs) should be allocated to which picking line and is known as the SKU to Picking Line Assignment Problem (SPLAP). The second tier, the SKU Location Problem (SLP), considers the positioning of the various SKUs in a picking line. The nal tier considers the sequencing of the orders for pickers within a picking line and is referred to as the Order Sequencing Problem (OSP). Collectively, these three tiers aim to achieve the objective of picking all the SKUs for all the orders in the shortest possible time. The decisions associated with each tier are made sequentially during the planning of a picking line. Each problem therefore relies on the information generated by its predecessing tier(s). Initially the OSP is addressed. A number of heuristic and metaheuristic approaches are presented, together with an exact formulation to solve this tier. The size of the problem is reduced by using a relaxation of the problem that may be solved exactly. A number of greedy tour construction heuristics, a scope and ranking algorithm, methods based on awarding starting locations with respect to preference ratios and a modi ed assignment approach was used to solve the OSP. Furthermore, a tabu search, simulated annealing, genetic algorithm and a generalised extremal optimisation approach are used to solve the OSP. The solution quality and computational times of all the approaches are compared for the data provided by Pep, with the generalised extremal optimisation approach delivering the best solution quality. Two methods from the literature was used to model the SLP, whereafter an ant colony system was used to maximise the number of orders in common between adjacent SKUs. A number of agglomerative clustering algorithms were used from which dendrograms could be constructed. Two novel heuristic clustering algorithms were considered. The rst heuristic calculates a distance between two clusters as the set of orders that have to collect all the SKUs in both clusters, whereas the second method is based upon the frequency of SKUs within a cluster. Little or no improvement was achieved in most cases. The SPLAP was introduced by means of a number of possibilities of how to formulate objectives. A possible exact formulation is presented, followed by a nearest neighbour search, which was initially used to construct new picking lines based on all data sets. A di erent approach was then taken by means of a tabu search where the waves of two or three picking lines were altered. Signi cant savings may be incurred for large data sets.
AFRIKAANSE OPSOMMING: Die opmaak van bestellings is die belangrikste aktiwiteit in 'n distribusiesentrum. Dit behels dat geskikte hoeveelhede produkte uit stoorplekke opgespoor en herpak moet word om aan kleinhandeltakke gestuur te word. Die bedrywighede binne een van Pep Stores Ltd. (Pep) se distribusiesentrums in Durban, Suid-Afrika, word beskou. Die sisteem vereis dat die werkers in 'n kloksgewyse rigting om 'n uitsoeklyn beweeg. Die beplanning van die uitsoeklyne kan verdeel word in drie besluite/probleme. Die eerste besluit is watter voorraadeenhede (VEs) toegewys moet word aan watter uitsoeklyn. Die tweede besluit is in watter vakkies in die uitsoeklyn die VEs geplaas moet word, en word die VE-plasings probleem (VLP) genoem. Die nale besluit is in watter volgorde bestellings opgemaak moet word in 'n uitsoeklyn, en staan bekend as die volgorde-van-bestellings-probleem (VBP). Die doel van al drie hierdie probleme is om al die bestellings in 'n uitsoeklyn in die kortste moontlike tyd af te handel. Die besluite wat verband hou met elke vlak van besluit word opeenvolgend gedoen tydens die beplanning van 'n uitsoeklyn. Die oplossing van elke subprobleem berus op die inligting van die voorafgaande probleme. Aanvanlik word die VBP beskou. 'n Aantal heuristiese en metaheuristiese benaderings word aangebied saam met 'n eksakte formulering om die derde vlak op te los. Die grootte van die probleem is verminder deur die gebruik van 'n verslapping van 'n eksakte formulering. 'n Aantal toerkonstruksie heuristieke, 'n omvang en rangorde algoritme, metodes wat gebaseer is op die toekenning van beginpunte met betrekking tot voorkeurverhoudings en 'n veralgemeende toewysingsprobleem is gebruik om die VBP op te los. 'n Tabu-soektog, gesimuleerde tempering, genetiese algoritme en 'n veralgemeende-ekstreme-optimering-benadering word ook gebruik om die VBP op te los. Die oplossingsgehalte en berekeningstye van al die benaderings word vergelyk vir werklike data wat verskaf is deur Pep. Die veralgemeende-ekstreme-optimering-benadering lewer die beste oplossingsgehalte. Twee metodes uit die literatuur is gebruik om die VLP te modelleer, waarna 'n mier kolonie stelsel gebruik word om die aantal bestellings wat aangrensende VEs in gemeen het te maksimeer. 'n Aantal groeperingsalgoritmes word gebruik wat dendrogramme kan lewer. Twee heuristiese groeperingsalgoritmes word oorweeg. Die eerste heuristiek bereken die afstand tussen twee groepe as die aantal bestellings wat al die VEs in beide groepe moet versamel, terwyl die tweede metode gebaseer is op die frekwensie van VEs binne 'n groep. Min of geen verbeterings is in die meeste gevalle gevind. Die eerste besluit word bekend gestel na aanleiding van 'n aantal moontlike maniere om die doelwitte te formuleer. 'n Moontlike eksakte formulering word aangebied. 'n Alternatiewe benadering is geneem deur middel van 'n tabu-soektog waar die golwe van twee of drie uitsoeklyne gewysig word. Beduidende besparings word gerealiseer vir groot datastelle.

Texto completoThis thesis dealt with the effects of vehicle design (pot-belly [PB] vs. flat-deck [FD]) and transport distances (45 min vs. 7 h) on animal welfare and pork quality of three Pietrain crossbreds (Pietrain 50% HALNn (50Nn), Pietrain 50% HALNN (50NN), and Pietrain 25% HALNN (25NN). Behavioural and physiological responses and pork quality parameters were measured. The relationship between body temperature as measured by infrared thermography (IRT) in the restrainer before stunning and other animal welfare and pork quality parameters was also studied. Results obtained from both short and long distance transportation indicated that genetics has a larger impact on animal welfare parameters and pork quality traits than trailer type. However, under short distance transportation the PB trailer model augmented the negative genotype-related defects as measured by physiological responses to stress and pork quality parameters. Pigs with 50% Pietrain crossbreeding, regardless of the HAL genotype, produced leaner carcasses but appeared to be more responsive to transport stress. Pork quality was not detrimentally affected by the proportion of Pietrain inheritance in the crossbred but by the presence of the HAL gene. The study of IRT body temperature suggests that ocular IRT may detect changes in body temperature associated with the physiological condition of pigs and may be considered a potential tool to predict pork quality variation under commercial conditions.

För att överbrygga detta gap har startupföretaget Bookboost skapat en chattwidget (artefakt) som läggs till på hotellets webbplats och länkas till användarnas chattappar. Denna artefakts nuvarande intuitivitet och möjlighet till framtida intuitivitetsförbättringar undersöks genom en fallstudie av upplevelsen hos både experter och vanliga användare. 10 deltagare – 5 hotellmedarbetare och 5 gäster – rekryterades via förfrågan i hotellfoajéer utifrån ett systematiskt urval och icke-slumpmässigt urval. Deltagarna varierade i ålder från 18 till 65 år, med 30% inom milleniegenerationen. Uppgiftsanalys, intervju, och frågeformulär tillämpades i användaranalysen. Forskaren fungerade som utvärderare och undersökte artefaktens brister och möjliga förbättringar med hjälp av aktivitetsteorins human-artifact model (HAM). Analyserna tyder på att dagens intuitivitet är ganska hög, men att det finns utrymme för förbättringar. Det verkar finnas en generationsskillnad mellan äldre och yngre användare, särskilt när det gäller tidsåtgången och preferensen för artefakten (jämfört med mer välbekanta kommunikationsmetoder). Intresset för och komforten med teknologianvändning var en faktor i intuiviteten. I allmänhet uppnådde de som var mer bekväma med teknik en högre poäng i zonen för proximal utveckling (ZPD). Förbättringar som kan öka intuitiviteten för artefakten föreslås, även om prövandet av dessa inte ryms inom ramen för denna studie. Framtida forskning kan undersöka om de föreslagna förbättringarna verkligen ökar artefaktens intuitivitet för användare i alla åldrar.

Although recent years have seen a dramatic increase in research on the relationship between space and crime, few studies have examined the impact of space on the juvenile justice outcomes of treatment non-completion and recidivism. Fewer yet have investigated how such effects might differ on those outcomes when disaggregated by the reason for non-completion and recidivism offense type. This study seeks to address those theoretical gaps by determining the effects of distance to treatment for juvenile offenders on type of treatment non-completion and recidivism. By estimating the effects of not only linear and temporal distance, but also social distance, this analysis represents a valuable inquiry into the influence of space on juvenile offenders. Data on juvenile offenders adjudicated in Philadelphia's Family Court to attend community-based treatment from 1996 through 2002 provide this study with 6,208 individual units of analysis. Data describing the neighborhoods in which the juveniles live and the programs that they attend are also included in this analysis. The use of hierarchical linear models allows for the simultaneous estimation of multiple levels of control variables when modeling the effects of distance to treatment. Separate models are constructed to estimate the direct effects of distance to treatment on treatment non-completion and then the subsequent, indirect effects of distance to treatment on juvenile recidivism. Results from two-level models that control for both neighborhood and program context indicate that distance to treatment does influence the likelihood of both treatment non-completion and recidivism. In general, distance to treatment was found to increase the likelihood of both treatment non-completion and recidivism as distance to treatment increases. Interaction effects that represent the joint effects of distance and race indicate that the impact of distance is generally greater for non-Whites, as they are more likely than Whites to fail to complete treatment as distance increases. Results from cross-classified models reveal limitations of the data related to statistical power and noise. Findings from this analysis contribute to several bodies of literature, including criminology and geography, and strongly support the consideration of distance to treatment by policymakers within the juvenile justice system.

Texto completoWhen exploring their environment, humans and other animals have the ability to use many sources of information to estimate the distance they travel. Several studies have shown that optic flow is a significant cue to perceive distance travelled. Furthermore, it was found that adding various viewpoint oscillations to a purely translational optic flow, simulating forward self-motion, modulated this perception. In a series of experiments, we tested whether the perception of distance travelled was also affected by viewpoint oscillation, similar to head motion during natural walking. A first series of experiments, participants were exposed to an immersive optic flow simulating forward self-motion and they were asked to indicate when they thought they had reached the remembered position of a previously seen target. Two further experiments aimed to test whether the idiosyncrasy of viewpoint oscillations affects the perception of distance travelled in stationary observers and whether the absence of their own viewpoint oscillation played an important role in subjects’ estimates, while they were walking on a treadmill. And finally, in a last experiment we tried to develop a dynamic measure of distance travelled to a previously seen target, with a continuous pointing task method. Overall, our results show that viewpoint oscillations play an important role in visual self-motion perception and that several parameters (including visual information, proprioceptive information and ecological aspects of natural walking) seem to be involved in this process

Texto completoThe purpose of the case study was to investigate what Airshoppen Travel Retail could take into consideration when designing their new warehouse layout. In order to carry out the study, a theoretical model was developed, the model focuses on how warehouse layout could be designed. The theoretical model analyzes the warehouse layout of two companies. The findings were then used to analyze and give recommendations to Airshoppen Travel Retail regarding what the company could take into consideration when designing their new warehouse layout. Interviews and observations showed that the development of the warehouses processes was adapted and limited by the lack of space in their warehouses. Previous research suggested that the design of a warehouse should be based on the choice of system, either manual or automatic. Inadequate design can lead to high costs, limited flexibility and reduced efficiency. An interesting aspect that the study highlighted was that the previous research mainly focuses on reducing travel distance, while the study's empirical basis showed that companies primarilyfocus on decreasing picking errors and increasing productivity. The results of the study were presented as recommendations to Airshoppen Travel Retail on how the company could design their new warehouse layout. The results showed the importance of choosing systems and control policies simultaneously to avoid limitations in the layout. Furthermore, with a manual system, implementation of zone picking could lead to increased efficiency. On a final note, careful calculations are required for the company to properly determine whether automation is a necessary and profitable investment.

Texto completoThis Master Thesis main objective is to answer a problem set by the Swedish Transport Administration: a common regional bicycle planning process would them cheaper and more comparable. They currently offer the planners a model developed by Kågeson in 2007. This model takes the form of a report which advises on when to build a bicycle path between cities or places of a region. Still, it is only used in only 6 of the 21 Swedish counties. Trafikverket requires a new planning support tool, more interactive and complete than the Kågeson model. Some new desired features are the separation of demand per purpose, the inclusion of e-bikes, different trip purposes, and a prioritization of the investments. The Degree Project work is to design and implement this tool, also called Planning Support System (PSS), which compares supply and demand for bicycle path to prioritizing infrastructure improvements. A main constraint for the model is that it needs to be cheap data-wise, but as complete and precise as possible. It bases on several open data providers, such as OpenStreetMap, the Swedish National Road Database (NVDB), or Travel Surveys from Sweden and the Netherlands. The result is a model, disaggregated by trip purpose and type of bicycle. The demand estimation part adapts a classic four-step transportation model to bicycle planning and limited data. For different trip purposes, trips are generated and distributed thanks to an origin-constrained gravity model. Bicycle mode choice is fit to actual travel behaviour through logistic regression with a binary logit model. The trips are then assigned to the network using the "all-or-nothing" assignment method through the Dijkstra algorithm. To evaluate bicycle supply, we used a metric called Level of Traffic Stress (LTS), which estimates the potential use of a network link by different parts of the population as a function of the road network variables. The prioritization ranking is then the ratio between demand and supply metrics. This new tool is implemented with the opensource Geographic Information System (GIS) called QGIS and with Python 3, and it is tested on Södermanland County.

Texto completoThe countries in the world have concluded agreements to prevent the global averagetemperature to exceed 2°C. To engage authorities to set an example they're required tohave an environmental management system. One of the universities environmentalaspects is student travel. This report presents the result from a survey of students' travelhabits where the carbon dioxide emission per year from students' travel to hometown,other study places and university have been calculated. The aim is to give theuniversities material to assess if the students' travel is a significant environmentalaspect. The carbon dioxide emission from a student that moved to the area to study wasmost caused by the travel to the hometown wich had a far distance and was frequentlydone. The carbon dioxide emission from a student that already lived in the area and adistance student was most caused by trips to the university wich for the student thatlived in the area was done frequently and had a short distance and for the distancestudent was done rarely with a far distance. When students that moved to the areatraveled to other study places and the university and when distance students traveled toother study places the carbon dioxide emission in the winter differed from the otherseasons wich shows that fewer students walked/biked in the winter. The students travelshould be seen as a significant environmental aspect in the universities environmentalwork. Environmental objectives and actions should be based on relevance andpossibility for the university.
Shao, Lin Han. "The Influence of Environmental, Organizational and Managerial Factors on Export Decisions and Export Performance". Electronic Thesis or Diss., Bordeaux, 2020. http://www.theses.fr/2020BORD0156.
Texto completoExport performance is an important research part of export study. Extensive empirical research has been carried out to identify and study the determinant factors of successful export performance. The factors associated with the three major axes of organizational, environmental, and managerial factors in the work of (Leonidou et al. 2002). The research aims to find how export performance is affected by environmental, organizational, managerial factors, especially, the psychic business distance and cultural distance, relationship management, international business travel, firms’ financial capabilities and complementary capabilities, specially, psychic distance – the extent to which the norms and values of two countries differ (Ford,1984, p. 102), when it comes to the potential interplay between business distance and cultural distance with managerial factors. The other observation is that international business depends gradually on transmitting complex information through vis-à-vis communication (Cristea, 2011). Companies vary in their performance because they use their resources in different ways (Shuleska et al. 2016). International business travel plays very important role in export business, especially for wine business, as the export managers practice ritual international business travel to meet the overseas prospective customers, organize wine tasting, participate in international wine fairs. Nevertheless, up to now, we have known very little about the impact of such travel on export performance.Hence, the thesis is organized as follows.First, we present a bibliometric study by analyzing 1344 publications from 1900 to 2019. Second, we examine the interacting effect of the two forms of psychic distance (business and cultural) on export relationship management. Specifically, this research examines the moderating role of cultural distance in the effect of business distance on different dimensions of relationship management and financial export performance. This research builds on a sample of 174 French export executives who were asked to rate their views of their relationship with their Chinese business counterpart in the wine trade,and their related performance. Third, we examine the impact of international business travel on export performance by integrating organizational factors (annual turnover) and strategic management (complementary capability) into the analysis with equally 174 French wine exporting firms.The systematic bibliometric study and two empirical studies reveal meaningful results which shed light on the export literature study and provides numerous contributions on the theoretical, methodological, and managerial levels related to export performance
