Human related accidents in high-risk industries amount to a significant economic hazard and incur tremendous damages, causing excessive operational costs and loss of life. The aviation industry now observes human-related accidents more frequently than in the past, an upswing attributable to cutting-edge technology usage and the complex systems employed by aviation organizations. Historically, aviation accidents have been attributed to individual unsafe behavior. However, contemporary accident causation models suggest that organizational-level factors influence individual safety performance, as human-related accidents take place in an organizational context. The present study examines the formation of organizational safety culture and influence on individuals' safety behavior in a police aviation environment. The theory of planned behavior guides the study model in explaining individual variability in safety behavior via organizational safety culture. The study conceptualized organizational safety culture and individual safety behavior as multidimensional constructs. Confirmatory factor analysis was conducted for each latent construct to validate the construct validity for each measurement model. Organizational safety culture was observed via safety climate facets, which contained four subcomponents including individual attitude, group norms, management attitude, and workplace pressures. Individual safety behavior contained violation and error components observed by self-reported statements. Structural equation modeling was conducted to test the study hypotheses. Utilizing a sample of 210 employees from the Turkish National Police Aviation Department, a 53-item survey was conducted to measure individuals' safety culture perceptions and self-reported safety behaviors. The results suggest that individual safety behavior is significantly influenced by organizational safety culture. Except for the relation between workplace pressures and intention, all suggested relations and correlations were statistically significant. The four-factor measurement model of organizational safety climate fit reasonably well to the data, and most correlations between the safety climate components were significant at the .05 level. Individuals' self-reported error behavior is positively associated with age, and individuals' self-reported violation behavior is positively associated with years of service. Overall, along with organizational safety culture, age and service-year variables accounted for 65% of the variance in intention, 55% of the variance in violation behavior, and 68% of the variance in error behavior. Lastly, no significant difference manifested among pilots, maintenance personnel, and office staff according to their self-related safety behaviors. The findings have theoretical, policy, and managerial implications. First, the theory of planned behavior was tested, and its usefulness in explaining individuals' safety behavior was demonstrated. The survey instrument of the study, and multi-dimensional measurement models for organizational safety climate and individual safety behavior were theoretical contributions of the study. Second, the emergence of informal organizational structures and their effects on individuals indicated several policy implications. The study also revealed the importance of informal structures in organizations performing in high-risk environments, especially in designing safety systems, safety policies, and regulations. Policy modification was suggested to overcome anticipated obstacles and the perceived difficulty of working with safety procedures. The influences of age on error behavior and years of service on violation behavior point to the need for several policy modifications regarding task assignment, personnel recruitment, health reports, and violation assessment policies. As well, managerial implications were suggested, including changing individuals' perceptions of management and group attitudes toward safety. The negative influence of anticipated obstacles and the perceived difficulties of safety procedures on individual safety behavior pointed out management's role in reducing risks and accidents by designing intervention programs to improve safety performance, and formulating proactive solutions for problems typically leading to accidents and injuries.

Master of Science / Department of Journalism and Mass Communications / Thomas H. Gould / This case study explores the gap in attitudes, information and contact between soldiers and civilians and what Army public affairs officers do to try and bridge that gap. The study was exploratory and as such, brought up more questions than it answered. In-depth interviews were conducted with three Army public affairs officers from three different Army installations. A total of five community leaders from towns surrounding the installations also were interviewed. Most of the comments from public affairs officers and community leaders were positive. While the public affairs officers felt they could do a better job telling the Army’s story if they had more resources, the community leaders didn’t necessarily feel they were missing out on information. Some stereotypes or biases were detected in comments suggesting the Army was only interested in helping itself and on the flip side that there are just some things civilians would not understand. Further research on the military-civilian gap, particularly the gaps between certain demographics, would be usefully not only in helping public affairs officers target their messages but also in helping military recruiters better connect with possible enlistees.

This study is a descriptive study which identifies the variables that inhibit participation by black merchants in a Retail Revitalization Loan Program (RRLP) that utilizes the public/private partnership concept. A sample of fifteen (15) black merchants were administered self-report questionnaires from a population of seventy (70) in Dallas, Texas through the stratified sampling method, utilizing SIC codes. From the response patterns of those surveyed, a Z-value was computed and tested at 1% level of significance, revealing that at least 85% of the black merchants identified conventional underwriting criteria as the primary cause for their lack of participation in the RRLP. Therefore, the null hypothesis was upheld.

New innovation often forces The rise of the sharing economy has created a host of regulatory challenges for both agencies and legislators. Specifically, the ride-sharing and short-term rental industries have faced significant challenges from incumbent industries, lawmakers, and the public. Evaluating the respective policy development of these industries and the strategies of the industry leaders provide a useful lens of analysis.

What are the policy-relevant factors that condition WASH sector performance in Sub-Saharan Africa? Close examination of three case study countries, Equatorial Guinea, Malawi, and Mauritania, reveals interesting insights. Delivery of WASH services is shaped to a large extent by the overall quality and structure of a country’s government. More specifically, having an excessive profusion of policy-making and policy-implementing actors can hinder WASH sector performance. Furthermore, governments may face strong incentives to invest more heavily in providing WASH services to urban areas over rural areas, and to invest more heavily in the water sub-sector than in the sanitation sub-sector. Adequate financing of WASH investment appears to be a necessary but not sufficient condition for performance in both the water and sanitation subsectors. Additionally, monitoring and evaluation appears to be a crucial factor in formulating and implementing effective policies. In the rural water subsector, a country’s institutional setup and technology choice can have a major impact on water source maintenance and operability.

American cities have proliferated in the post-War era. More than 2,000 new cities were founded between 1950 and 2000. While the history of the local government boom has been documented, research into urban fragmentation has explored why there is no consolidation of metropolitan areas rather than exploring why Americans chose fragmentation initially. This dissertation proposes that individuals create new jurisdictions because individuals prefer to have governments which give them the services individuals desire, even if they could have similar (but not perfect) services cheaper in a larger jurisdiction. Individuals, however, must balance the benefit they get from better fitting cities with the price they must pay to live within the small cities. In the first part of the dissertation, I synthesize the literatures on urban governance and fragmentation with the literature on interest groups. This synthesis builds the argument for conceiving cities as interest groups and contributes a theory of urban behavior as the behavior of organized interest groups. I argue that urban fragmentation should exist anywhere there are urban areas –not only metropolises –and that fragmentation is produced by diversity in the population and constrained by the resources available for the formation of cities. In the second part of the dissertation, I analyze the fragmentation of both metropolitan and non-metropolitan areas to determine what drives fragmentation. I use Poisson regression on 2-period panel data from 1992 and 2002 collected from various public sources. I find that there are differences in the forms of fragmentation in the metropolis and the non-metropolis. In both types of urban settlement, fragmentation is driven by political and population diversity and available resources for forming cities. Legal authority and intergovernmental revenue are particularly important. Finally, I turn my attention to cities’ interactions with each other. I use a survey of Kentucky mayors, fielded with the Kentucky League of Cities, to determine why mayors of different cities to communicate with each other. Using specialized network methods I find that mayor-to-mayor contact is not based on goal and interest similarities as expected, but rather depends on sharing an organization which encourages communication –an Area Development District.

Attainment of greater efficiency in hospital operations has become a goal highly sought after as a result of several factors including skyrocketing costs. The possibility that the different incentives associated with ownership type might affect efficiency has been covered thoroughly in the literature. There are numerous studies comparing for-profit to not-for-profit hospitals or public to private hospitals. Analysis of federal ownership, however, has been less studied. In particular, comparisons involving military hospitals are non-existent, attributed to data availability and an assumption that military hospitals are too different from civilian facilities. This dissertation employs a cross-sectional Stochastic Frontier Analysis (“SFA”) of 2006 data to compare the technical efficiency of military, for-profit, not-for-profit, and other government hospitals, controlling for differences in patients, scope of work, physicianhospital working arrangements, and other structural characteristics. Four model specifications are examined, varying the method of accounting for heterogeneity of case mix. One of the specifications uses a distance function technique to allow for specific inclusion of multiple outputs, namely inpatient and outpatient workload. Results obtained using SFA are validated using Data Envelopment Analysis (“DEA”) and compared with results produced through simple ratio analysis. Estimates of overall technical efficiency ranged from 76% to 80%. The analysis found no significant correlation between ownership category and technical efficiency. Factors found to be significantly correlated with greater technical efficiency include younger average patient age, more female patients, percentage of surgical inpatient work, percentage of circulatory system-based work, accreditation, and having all credentialed physicians (i.e. no physician employees). Pooled-vs.-partitioned analysis showed that military hospitals are indeed different, but not enough to render comparisons meaningless. Data Envelopment Analysis produced comparable individual hospital efficiency scores (correlations of approximately 0.6 between like specifications using SFA and DEA) and comparable average efficiency (~87%). Ratio analysis results were sensitive to the specific ratio analyzed. This dissertation adds to the body of literature on the relationship between ownership and hospital technical efficiency. It is the first comparison of military and civilian hospital technical efficiency.

This thesis examines U.S. immigrant and refugee policy and policy discourse to understand the formation of Muslims as particular sites of risk as immigrants in the War on Terror. Theorists of international relations theorize securitization as a process in which state actors begin to use the language of security in considering the regulation and governance of a certain policy issue area. I argue that the securitization of various figures who are Muslim or are linked to Muslim-majority countries in post-9/11 immigrant and refugee policy and political discourse contributes to political conditions under which Islam is understood as the only trusted identifier that marks the potential terrorist.Chapters II and III of this thesis explore two case studies of the securitization of figures who are Muslim or presumed to be Muslim: the conversation in 2002 and 2003 about the risk presented by international studies from Muslim-majority students; and that of Syrian refugees as would-be terrorists in 2015 and 2016. In the final chapter, I turn to that which I suggest is a realization of the logic that treats all Muslims as risk, the Trump executive orders heavily restricting immigration from Muslim-majority countries, and document the judicial contestations that follow.

The purpose of this mixed methods qualitative case study is to gain a deeper understanding about the factors that contribute to and/or hinder women’s participation in the construction industry by examining women’s experiences within one very industry-specific, male-dominated nontraditional occupation (NTO)—the concrete industry. In this study I utilized a combination of methods including interviews and survey research, as well as case analysis of an organization specifically involved with this population, the Women In Concrete Alliance (WICA). This investigation identifiesd some of the reasons why women’s participation remains low, discusses some of ways that the private, public, and educational sectors have set out to address those shortages, how women working in the field felt feel about those initiatives based upon their experiences, and what systems of support these women draw upon to remain active in a male-dominated profession. As women’s associations within NTOs are one relatively formal potential means of support for women facing occupational isolation, this study also examines different types of organizations to which women working in NTOs belong (e.g. membership, educational, advocacy, trades). I want to know in what ways the organizations benefit members; how the organizations support themselves or are supported financially.
