This dissertation is about the factors that influence heat wave preparedness of Midwestern health departments, and the climate change perceptions of public health officials. Heat waves have historically impacted the Midwest and, due to the variable pattern of these events, are full of uncertainties. Climate change intensifies the threat of heat waves; therefore, it is important for public health officials to incorporate methods for addressing climate change into their short and long term plans and preparedness models. This study is unique, because it goes beyond previous work that has been done with heat wave preparedness by speaking with public health officials to understand the complexities of heat wave planning. Applying a comparative case study methodology to this study was important to see how three states, in varying stages of climate change preparedness, function regarding emergency planning, decision making, and collaboration. Further, interview discussions regarding climate change demonstrate the need to further assist public health with their mitigation and adaptation efforts. Topics within Chapter One describe the study framework, study significance, discuss the incorporated methodology, and the dissemination of results. In Chapter Two, I construct the scholarly framework for this study by examining climate change and public health impacts, how policy shapes program planning with regard to heat waves, the sociological implications of heat waves including communicative properties and community organizing, and heat wave preparedness plan evaluation. Chapter Three focuses on the methodology guiding this project as well as the research questions. Research questions focused on preparation for heat waves, communication among state and local health departments, climate change perceptions of health officials, and finally, the influence of grant funding on preparedness efforts. This study was constructed using an interpretive paradigm to guide a comparative case study framework for comparing heat wave preparedness of three Midwestern States. Using document analysis and semi-structured interviews, I was able to discuss the concept of preparedness with public health officials including emergency preparedness coordinators, environmental health directors, and emergency managers. In Chapters Four and Five, I developed the uniqueness of each case, and then built a broader story by examining findings across the cases. I met with 22 individuals representing fourteen local health departments, two state health departments, one city health department, two emergency management agencies, and one state climatologist office. Analysis was threaded into both Chapters Four and Five by exploring within (locality, misconception, and camaraderie) and cross (passive leadership, transitions, expectations, reputation, and strategies) case themes. In Chapter Six, I discuss the study findings by incorporating the social ecological model as well as cited literature. Finally, Chapter Seven revisits the study significance and implications for best possible practices in health and public health education. Climate change is one of the greatest threats to public health, and heat waves are only one anticipated threat from enhanced warming. This study sheds light on the importance of climate literacy and preparedness for all-hazards approaches in public health planning.

M.Sc. (Informatics) / Information is power. Any organization must secure and protect its entire information assets. Management is responsible for the well-being of the organization and consequently for computer security. Management must become and stay involved with the computer security situation of the organization, because the existence of any organization depends on an effective information system. One way in which management can stay continually involved and committed with the computer security situation of the organization, is by -, the periodic evaluation of computer security. The results from this evaluation process can initiate appropriate actions to increase computer security in areas needed. For effective management involvement, a tool is needed to aid management in monitoring the status of implementing computer security on a regular basis. The main objective of this dissertation is to develop such a management tool. Basically the thesis consists of three parts, namely framework for effective computer security evaluation, the definition of the criteria to be included in the tool and lastly, the tool itself. The framework (chapters 1 to 6) defines the basis on which the tool (chapters 7 to 9) is built, e.g. that computer security controls need to be cost-effective and should aid the organization in accomplishing its objectives. The framework is based on a two dimensional graph: firstly, tho various risk areas in which computer security should be applied and secondly, the severity of controls in each of these areas. The tool identifies numerous risk areas critical to the security of the computer and its environment. Each of these risk areas need to be evaluated to find out how well it is secured. From these results an overall computer security situation is pictured. The tool is presented as a spreadsheet, containing a number of questions. The built -in formulae in the spreadsheet perform calculations resulting in an appreciation of the computer security situation. The results of the security evaluation can be used by management to take appropriate actions regarding the computer security situation.

The increasing reliance on information technology to support business processes has emphasised the need for information security mechanisms. This, however, has resulted in an ever-increasing workload in terms of security administration. Security administration encompasses the activity of ensuring the correct enforcement of access control within an organisation. Access rights and their allocation are dictated by the security policies within an organisation. As such, security administration can be seen as a policybased approach. Policy-based approaches promise to lighten the workload of security administrators. Separation of duties is one of the principles cited as a criterion when setting up these policy-based mechanisms. Different types of separation of duty policies exist. They can be categorised into policies that can be enforced at administration time, viz. static separation of duty requirements and policies that can be enforced only at execution time, viz. dynamic separation of duty requirements. This dissertation deals with the specification of both static separation of duty requirements and dynamic separation of duty requirements in role-based workflow environments. It proposes a model for the specification of separation of duty requirements, the expressions of which are based on set theory. The model focuses, furthermore, on the enforcement of static separation of duty. The enforcement of static separation of duty requirements is modelled in terms of invariant conditions. The invariant conditions specify restrictions upon the elements allowed in the sets representing access control requirements. The sets are themselves expressed as database tables within a relational database management system. Algorithms that stipulate how to verify the additions or deletions of elements within these sets can then be performed within the database management system. A prototype was developed in order to demonstrate the concepts of this model. This prototype helps demonstrate how the proposed model could function and flaunts its effectiveness.

Orientation – Talent mindset (TM) and organisational commitment (OC) are two separate constructs and it appears that a positive relationship exists between these two constructs. Research Purpose – The study aims to determine the relationship between the talent mindset and organisational commitment of academic heads of departments. Motivation for the Study – There is a vast problem in the higher education sector with regards to retaining academic staff members. In order for higher education institutions to attract and more specifically retain academic talent, one needs to implement a sound talent management model. Before such a model can be implemented with success, the organisation first needs to have a positive talent mindset. The relationship between talent mindset and organisational commitment may provide a means to develop appropriate interventions or strategies in order to enhance the talent mindset by focusing on improving the organisational commitment and vice versa. Research Design, Approach and Method – Two instruments, namely the Talent Mindset Index (TMI) and Organisational Commitment Questionnaire (OCQ), were administered to a sample of 116 heads of departments at a leading university in South Africa, 53 completed questionnaires were obtained. The responses were analysed using correlation analysis and quantitative techniques. Main Findings – Results confirm that the presence of OC is associated with a positive TM Practical / Managerial Implications – The study provides evidence that there is a correlation between OC and the TM of academic heads of departments. Thus, if management utilises existing techniques to increase OC, this should lead to the enhancement of the head of departments’ TM. The enhanced TM would equip them to implement a talent management model to attract and retain academic staff. Contribution / Value Add – By enhancing the TM of the heads of departments through utilising existing techniques to increase OC, management should be in a stronger position to implement a talent management model effectively. / Dissertation (MA)--University of Pretoria, 2014. / lk2014 / Human Resource Management / MA / Unrestricted

Social media offers numerous opportunities to companies, organizations and government agencies to communicate with people outside their organization, to promote their interests and to better serve their customers, or as in the case with government agencies, to better serve their citizens. However, little is known about how police departments in particular use social media. This research study explores why police departments use social media, how they manage their social media tools, and the problems and challenges experienced as they use social media. This qualitative study is largely guided by grounded theory. The data were collected from a study population using local police departments in the Dallas-Fort worth (DFW) area principal cities using both individual interviews with police departments’ social media officers and observations of these departments’ online social media tools (in particular, Facebook and Twitter). This study has shown that the DFW area city police departments are using social media quite extensively to keep the public informed and often for investigative purposes. There are some success factors to adopting and using these tools, such as the motivation of department staff and their benefits, successful implementation of the tools, the simplicity of using tools and that it is absolutely free.

archives@tulane.edu / Public health finance is still a relatively young field and, as such, many questions have yet to be asked—and answered. To date, few have examine how specific revenue streams—alone or in combination—shape local health departments’ (LHD) resources and capacity to accomplish their public health missions. Given ongoing policy conversations about financing for public health, it’s important for researchers to rigorously examine the and the potential costs and benefits associated with different revenue sources. Introduction Chapter: The central thesis for the body of work encapsulated by this dissertation is simple: where money comes from matters. This chapter critically examines published evidence and theory linking public health financing mechanisms and their interactions to LHD operations, outputs, and even outcomes. The chapter also introduces situates the specific research questions addressed in this dissertation within a broader conceptual framework. Paper 1: The first paper examines the relationship between revenue diversification and revenue volatility among Washington State LHDs. Using fixed effects linear regression models and revenue data reported during 1998-2014 by all LHDs operating in Washington State, the paper finds little evidence to suggest revenue diversification is significantly associated with revenue volatility. Paper 2: The second paper evaluates whether available revenue sources differentially effected the scope of programs provided by Washington State LHDs between 2000 and 2011. Using two measures of program scope and both linear and non-linear fixed effects panel regression models, the paper finds that only funding received from federal Medicaid was consistently and significantly associated with both measures of program scope. Paper 3: The third paper examines changes in total LHD expenditures in Washington State between 2006 and 2013 following introduction of a new state funding program to support core public health services and infrastructure. Using a pre-post design regression model to evaluate changes in LHD expenditures, the paper finds overall spending among LHDs significantly increased with receipt of the new state funds in the first years of the program. However, those increases were not sustained over the longer term Conclusion Chapter: The final chapter reviews findings from the three papers and discusses their implications for public health policy, practice, finance, and research. / 1 / Abigail Hope Viall

Introduction: The appropriate role of local health departments (LHDs) as a clinical service provider remains a salient issue. This study examines differences in clinical service provision among rural/urban LHDs for early periodic screening, diagnosis, and treatment (EPSDT) and prenatal care services. Methods: Data collected from the 2013 National Association of County and City Health Officials Profile of Local Health Departments Survey was used to conduct a cross-sectional analysis of rural/urban differences in clinical service provision by LHDs. Profile data were linked with the 2013 Area Health Resource File to derive other county-level measures. Data analysis was conducted in 2015. Results: Approximately 35% of LHDs in the analysis provided EPSDT services directly and 26% provided prenatal care. LHDs reporting no others providing these services in the community were four times more likely to report providing EPSDT services directly and six times more likely to provide prenatal care services directly. Rural LHDs were more likely to provide EPSDT (OR=1.46, 95% CI=1.07, 2.00) and prenatal care (OR=2.43, 95% CI=1.70, 3.47) services than urban LHDs. The presence of a Federally Qualified Health Center in the county was associated with reduced clinical service provision by LHDs for EPSDT and prenatal care. Conclusions: Findings suggest that many LHDs in rural communities remain a clinical service provider and a critical component of the healthcare safety net. The unique position of rural LHDs should be considered in national policy discussions around the organization and delivery of public health services, particularly as they relate to clinical services.
