Transferability of community-based macro-level collision prediction models for use in road safety planning applicationsKhondaker, Bidoura 11 1900 (has links)
This thesis proposes the methodology and guidelines for community-based macro-level CPM
transferability to do road safety planning applications, with models developed in one spatial-temporal
region being capable of used in a
different spatial-temporal region. In doing this.
the macro-level CPMs developed for the Greater Vancouver Regional District (GVRD) by
Lovegrove and Sayed (2006, 2007) was used in a model transferability study. Using those
models from GVRD and data from Central Okanagan Regional District (CORD), in the
Province of British Columbia. Canada. a transferability test has been conducted that involved
recalibration of the 1996 GVRD models to Kelowna, in 2003 context. The case study was
carried out in three parts. First, macro-level CPMs for the City of Kelowna were developed
using 2003 data following the research by GVRD CPM development and use. Next, the 1996
GVRD models were recalibrated to see whether they could yield reliable prediction of the
safety estimates for Kelowna, in 2003 context. Finally, a
comparison between the results of
Kelowna’s own developed models and the transferred models was conducted to determine
which models yielded better results.
The results of the transferability study revealed that macro-level CPM transferability was
possible and no more complicated than micro-level CPM transferability. To facilitate the
development of reliable community-based, macro-level collision prediction models, it was
recommended that CPMs be transferred rather than developed from scratch whenever and
wherever communities lack sufficient data of adequate quality. Therefore, the transferability
guidelines in this research, together with their application in the case studies, have been
offered as a contribution towards model transferability to do road safety planning
applications, with models developed in one spatial-temporal region being capable of used in
a different spatial-temporal region.

Social Capital and Institutional Transition: Regional Context for Network Use in Job Search in Russia, 1985-2001Mayorova, Olga Vladislavovna January 2008 (has links)
Current research on network use in the labor market focuses primarily on network morphology. In this dissertation, I use hierarchical regression to examine the influence of macro-level context on network use in job search.This study relies on a unique data set that combines individual job history data for years 1985 through 2001 collected by the Survey of Social Dynamics and Migration in Russia (SSMDR) in 40 regions in 2001-2002 and corresponding regional macro-economic data published by Goskomstat, the State Statistical Committee of the Russian Federation.The first question of this study focuses on what accounts for the temporal and regional variation in personal network use in the Russian labor market. I find that, for the post-Soviet period, increase in network use in job search can be attributed to the growth of the private sector: Russian employers are becoming "social capitalists" who take advantage of the resources personal connections can offer. I also find that the chances of finding a new job through personal ties are higher in the regions with larger small business sectors and in the regions with lower economic performance.Next I examine how regional economic performance and unemployment affect workers' chances of getting new jobs in the private sector and in smaller size organizations by means of personal networks. The analysis shows that social networks do lead to employment in the private sector and that this relationship is positively affected by regional economic performance, but not by unemployment rate. I also find here that social ties are likely to lead to new jobs in small organizations, but that this relationship does not vary by region.Finally, I investigate how regional economic performance and unemployment rates affect wages for jobs found through personal networks in the private sector and in small organizations. I find that while the private sector rewards network use, small organizations do not. The relationship between network use and wages does not vary by region. That is, regional economic performance does not have an effect on this relationship.

Child Murder: A Re-examination Of Durkheim's Theory Of HomicideTetzlaff-Bemiller, Melissa 01 January 2013 (has links)
The current study examines county-level characteristics and their impact on child homicide. This work uses Durkheimian theory and tests the concept of solidarity by using variables that constitute integration and regulation. In addition, some variables are drawn from other theoretical perspectives, mainly social disorganization and anomie theories, to better explore additional macro-level indicators. Data were obtained from multiple locations. Homicide data for children, from birth through five years, utilized in this work came from the National Incident-Based Reporting System. County level socio-demographics were obtained from the Census. Political party affiliation (Republican or Democrat) came from Politico, and religious data were collected by InfoGroup and organized into groups by the Association of Religion Data Archives. This study aims to increase our understanding of how macro-level contextual and situational factors may help guide policy makers, law enforcement personnel, and any other individuals who are concerned with areas where there are varying degrees of risk for child homicide

OPTIMAL WATER QUALITY MANAGEMENT STRATEGIES FOR URBAN WATERSHEDS USING MACRO-LEVEL SIMULATION MODELS LINKED WITH EVOLUTIONARY ALGORITHMSTufail, Mohammad 01 January 2006 (has links)
Urban watershed management poses a very challenging problem due to the varioussources of pollution and there is a need to develop optimal management models that canfacilitate the process of identifying optimal water quality management strategies. Ascreening level, comprehensive, and integrated computational methodology is developedfor the management of point and non-point sources of pollution in urban watersheds. Themethodology is based on linking macro-level water quality simulation models withefficient nonlinear constrained optimization methods for urban watershed management.The use of macro-level simulation models in lieu of the traditional and complexdeductive simulation models is investigated in the optimal management framework forurban watersheds. Two different types of macro-level simulation models are investigatedfor application to watershed pollution problems namely explicit inductive models andsimplified deductive models. Three different types of inductive modeling techniques areused to develop macro-level simulation models ranging from simple regression methodsto more complex and nonlinear methods such as artificial neural networks and geneticfunctions. A new genetic algorithm (GA) based technique of inductive modelconstruction called Fixed Functional Set Genetic Algorithm (FFSGA) is developed andused in the development of macro-level simulation models. A novel simplified deductivemodel approach is developed for modeling the response of dissolved oxygen in urbanstreams impaired by point and non-point sources of pollution. The utility of this inverseloading model in an optimal management framework for urban watersheds isinvestigated.In the context of the optimization methods, the research investigated the use of parallelmethods of optimization for use in the optimal management formulation. These includedan evolutionary computing method called genetic optimization and a modified version ofthe direct search method of optimization called the Shuffled Box Complex method ofconstrained optimization. The resulting optimal management model obtained by linkingmacro-level simulation models with efficient optimization models is capable ofidentifying optimal management strategies for an urban watershed to satisfy waterquality and economic related objectives. Finally, the optimal management model isapplied to a real world urban watershed to evaluate management strategies for waterquality management leading to the selection of near-optimal strategies.

Gender Equality in Higher Education : A Comparative study of Sweden and IndiaJanoris, Dhiviya, Prela, Paula January 2019 (has links)
ABSTRACT Title: Gender Equality in Higher Education- Comparative study in Sweden and India Level: Final assignment for Master’s Degree in Business Administration Authors: Dhiviya Janoris and Paula Prela Supervisor: Maria Fregidou-Malama Examiner: Daniella Fjellström Date: May 2019 Aim: The aim of this study is to understand gender equality in higher education in two different countries, Sweden and India. Method: The study uses a qualitative study method and a constructivism approach. We conducted 11 semi-structured interviews and document experiences regarding gender equality. We had 6 interviews from the University of Gävle, Sweden and 5 interviews from Patrician College, India. Result and Conclusions: The results have shown that there is gender equality within the University of Gävle and Patrician college. However, there can be improvements made regarding the vertical and horizontal segregation in both universities. Additionally, when examining Patrician College on a macro level, it is shown that the parental leave policies and the gender wage gap has a large impact on gender equality. Suggestions for future study: It can be suggested that future study in this topic concentrate on to understand why there is a majority of male professors rather than female professors. Additionally, the reasons as to why there is a wider gender wage gap in India and poor parental leave policies should be examined. Contribution of the thesis: The theories are used to understand gender equality in different dimensions and its relationship with the different levels of the construct of gender as a social structure with the help of different theories. Keywords: Gender Equality, Individual level, Interactional level, Macro level, University of Gävle, Patrician College.

State Dominance and Political Corruption: Testing the Efficacy of an Alternate Configuration of Institutional-Anomie Theory Cross-NationallyTrent, Carol L. S. 20 June 2008 (has links)
Extant assessments of Messner and Rosenfeld's institutional-anomie theory (1994) have generally supported the thesis that, in social collectives where the economy dominates, non-economic institutions (i.e. the family, education, polity) are rendered feeble, unable to exert their normative controls. The cultural values of these societies place primacy on "making it" (monetary success), while at the same time placing a much weaker emphasis on the licit means of achieving these goals. The resultant state is one of anomie, conducive to crime. Messner and Rosenfeld have extended their argument stating that it is not economic dominance per se that contributes to high crime rates, but any tip in the institutional balance of power. The current study examines one of these configurations which hypothesizes that, in nation-states where the state dominates other institutions, the dominant cultural orientation is one of moral cynicism, conducive to corruption-prone behaviors. Using macro-level data, the current study assesses the efficacy of this alternate configuration of institutional-anomie theory as a predictor of corruption cross-nationally. Using a sample of 125 nations, state dominance is positively related to corruption. The effects of the state were both mediated and moderated by economic strength, measured as levels of industrialization.

Elite Deviance, Organized Crime, and Homicide: A Cross-National Quantitative AnalysisTrent, Carol L.s. 01 January 2015 (has links)
Both elite deviance, committed by the upper echelons of society, and organized crime threaten development and the rights and security of people across and within nations; however empirical research on these topics is limited, especially in the field of criminology. This study addresses this gap in the literature by testing hypotheses derived from Simon’s symbiotic theory of elite deviance, which posits that direct and indirect relationships exist between elite deviance, organized crime, and conventional crimes exist (2008). The intervening effects of national culture and political economic ideology are also considered.
To test the research hypotheses, this study uses homicide rates, corruption and organized crime measures, and indicators of national culture from 114 nations. Findings suggest that empirical linkages exist between elite deviance, organized crime and conventional deviance at the cross-national level. These data suggest the level of corruption and organized crime within a nation are better predictors of homicide than conventional explanations of violent crime (e.g., modernization/development, opportunity/routine activities). Furthermore, organized crime partially mediated the relationship between corruption and homicide rates in the same (positive) direction. This implies that the criminogenic effect of elite deviance on non-elite deviance operates indirectly through organized crime. The corruption-homicide relationship was also partially mediated by a national culture of moral cynicism and capitalist economic conditions. Although not definitive given methodological concerns and alternate theoretical explanations, this study provides avenues for future research into the underlying social processes that influence the crime rate within nations.

Use of Advanced Techniques to Estimate Zonal Level Safety Planning Models and Examine their Temporal TransferabilityHadayeghi, Alireza 24 September 2009 (has links)
Historically, the traditional planning process has not given much attention to the road safety evaluation of development plans. To make an informed, defensible, and proactive choice between alternative plans and their safety implications, it is necessary to have a procedure for estimating and evaluating safety performance. A procedure is required for examining the influence of the urban network development on road safety, and in particular, determining the effects of the many variables that affect safety in urban planning.
Safety planning models can provide a decision-support tool that facilitates the assessment of the safety implications of alternative network plans. The first objective of this research study is to develop safety planning models that are consistent with the regional models commonly used for urban transportation planning. Geographically weighted Poisson regression (GWPR), full-Bayesian semiparametric additive (FBSA), and traditional generalized linear modelling (GLM) techniques are used to develop the models. The study evaluates how well each model is able to handle spatial variations in the relationship between collision explanatory variables and the number of collisions in a zone. The evaluation uses measures of goodness of fit (GOF) and finds that the GWPR and FBSA models perform much better than the conventional GLM approach. There is little difference between the GOF values for the FBSA and GWPR models.
The second objective of this research study is to examine the temporal transferability of the safety planning models and alternative updating methods. The updating procedures examine the Bayesian approach and application of calibration factors. The results show that the models are not temporally transferable in a strict statistical sense. However, relative measures of transferability indicate that the transferred models yield useful information in the application context. The results also show that the updated safety planning models using the Bayesian approach predict the number of collisions better than the calibration factor procedure.
