Self-Management of Disaster Risk and Uncertainty: The Role of Preventive Health in Building Disaster Resilience

Gowan, Monica Elizabeth January 2011 (has links)
One of the great challenges facing human systems today is how to prepare for, manage, and adapt successfully to the profound and rapid changes wreaked by disasters. Wellington, New Zealand, is a capital city at significant risk of devastating earthquake and tsunami, potentially requiring mass evacuations with little or short notice. Subsequent hardship and suffering due to widespread property damage and infrastructure failure could cause large areas of the Wellington Region to become uninhabitable for weeks to months. Previous research has shown that positive health and well-being are associated with disaster-resilient outcomes. Preventing adverse outcomes before disaster strikes, through developing strengths-based skill sets in health-protective attitudes and behaviours, is increasingly advocated in disaster research, practise, and management. This study hypothesised that well-being constructs involving an affective heuristic play vital roles in pathways to resilience as proximal determinants of health-protective behaviours. Specifically, this study examined the importance of health-related quality of life and subjective well-being in motivating evacuation preparedness, measured in a community sample (n=695) drawn from the general adult population of Wellington’s isolated eastern suburbs. Using a quantitative epidemiological approach, the study measured the prevalence of key quality of life indicators (physical and mental health, emotional well-being or “Sense of Coherence”, spiritual well-being, social well-being, and life satisfaction) using validated psychometric scales; analysed the strengths of association between these indicators and the level of evacuation preparedness at categorical and continuous levels of measurement; and tested the predictive power of the model to explain the variance in evacuation preparedness activity. This is the first study known to examine multi-dimensional positive health and global well-being as resilient processes for engaging in evacuation preparedness behaviour. A cross-sectional study design and quantitative survey were used to collect self-report data on the study variables; a postal questionnaire was fielded between November 2008 and March 2009 to a sampling frame developed through multi-stage cluster randomisation. The survey response rate was 28.5%, yielding a margin of error of +/- 3.8% with 95% confidence and 80% statistical power to detect a true correlation coefficient of 0.11 or greater. In addition to the primary study variables, data were collected on demographic and ancillary variables relating to contextual factors in the physical environment (risk perception of physical and personal vulnerability to disaster) and the social environment (through the construct of self-determination), and other measures of disaster preparedness. These data are reserved for future analyses. Results of correlational and regression analyses for the primary study variables show that Wellingtonians are highly individualistic in how their well-being influences their preparedness, and a majority are taking inadequate action to build their resilience to future disaster from earthquake- or tsunami-triggered evacuation. At a population level, the conceptual multi-dimensional model of health-related quality of life and global well-being tested in this study shows a positive association with evacuation preparedness at statistically significant levels. However, it must be emphasised that the strength of this relationship is weak, accounting for only 5-7% of the variability in evacuation preparedness. No single dimension of health-related quality of life or well-being stands out as a strong predictor of preparedness. The strongest associations for preparedness are in a positive direction for spiritual well-being, emotional well-being, and life satisfaction; all involve a sense of existential meaningfulness. Spiritual well-being is the only quality of life variable making a statistically significant unique contribution to explaining the variance observed in the regression models. Physical health status is weakly associated with preparedness in a negative direction at a continuous level of measurement. No association was found at statistically significant levels for mental health status and social well-being. These findings indicate that engaging in evacuation preparedness is a very complex, holistic, yet individualised decision-making process, and likely involves highly subjective considerations for what is personally relevant. Gender is not a factor. Those 18-24 years of age are least likely to prepare and evacuation preparedness increases with age. Multidimensional health and global well-being are important constructs to consider in disaster resilience for both pre-event and post-event timeframes. This work indicates a need for promoting self-management of risk and building resilience by incorporating a sense of personal meaning and importance into preparedness actions, and for future research into further understanding preparedness motivations.

An analysis of security measures implemented on commercial private game reserves in Limpopo

Herman, Dewald Gustav 29 November 2020 (has links)
South Africa presently experiences high levels of crime daily. Although crime is accepted as an everyday occurrence for its citizens, it affects the economy of the country. This study analysed security measures implemented on Commercial Private Game Reserves (CPGRs) in Limpopo and the impact of crime thereof. CPGRs are enclosed areas containing various species of fauna and flora. Visitors from domestic and foreign origins visit these reserves to enjoy nature and its tranquillity. This study analysed the security measures to determine their effectiveness for CPGRs. The study further explored the use of security risk management strategies and risk assessments as crime reduction tools. The study was carried out using a case study research design. Data were collected by the researcher using three methods: observation, onsite checklists and semi-structured one-on-one interviews which were conducted on site. Validity and reliability indicate the trustworthiness of the study. The researcher reduced the data gathered through the use of thematic data analysis. Interviews were transcribed and themes were created and identified by the researcher. The comprehensive data indicated the importance of a security risk manager on a CPGR. The research found that very few security risk managers are employed and that managers of security risks employed on CPGRs have various titles. However, while the CPGRs have similar risks, their risk reduction strategies vary. The most commonly used measures are people, physical and technological measures with each having various subdivisions. The security measures implemented by CPGRs in the Limpopo province which were analysed are not formulated using a scientific approach as most properties do not make use of a formal security risk assessment. The study is deemed valuable as a model was developed from the findings that could be used by game reserves to guide them to apply relevant security measures. A formal security programme is often limited due to financial constraints of the reserve or the reserve owners, however, not all strategies should be considered as a financial expense as much can be done without exhausting financial reserves. The findings contributed to making recommendations to improve the overall security of CPGRs. This study encourages more research into the subject to improve the security industry and to stimulate the tourism industry. / Security Risk Management / M. Tech. (Security Management)

A test of the expanded AIDS risk reduction model managing risk to me, risk to you and risk to us

Collins, Brian Todd II January 2015 (has links)
Indiana University-Purdue University Indianapolis (IUPUI) / Currently, 1.2 million people in the United States are living with HIV (Human Immunodeficiency Virus) infection, while one in eight are unaware of their infection status. The purpose of this study was to test the ability of the expanded ARRM to see if the model contributed something to the research of why people protect themselves from HIV. To add to the research regarding motivating factors of HIV protection, we decided to add two concepts to the ARRM; partner protection and relationship preservation. Findings of the study suggest HIV-positive partners are motivated to using condoms to protect their partners especially when they believe their partners are at risk for contracting HIV. Relationship preservation results illustrated that when people fear of losing their relationship they are willing to do whatever it takes to keep the relationship going, even at the cost of contracting HIV. By extending the ARRM, as well as incorporating HIV status, we now can begin understanding the many motivating factors towards why people are and are not using condoms to protect themselves or their partner.

Active Lightweight – End effector (ALE) for the collaborative Robotics

Chen, Liang 09 December 2022 (has links)
This thesis provides a systematic guideline for evaluating, integrating and designing the collaborative end effector system associated with commercially available collaborative robots (cobots). On the basis of ISO/TS 15066:2016, customers’ demands are categorised as a macro demand framework and micro demand variables, which are parameterised and hierarchised. By analysing these parameters, the collaborative degree is determined to correlate the hazards with protection measures, which can demonstrate the collaborative safety level transparently. After that, the safety protection measures are specifically proposed corresponding to the potential risks. Finally, an industrial application is evaluated, a novel adapter utilised on the UR5 cobot is illustrated, and its characteristics for the collaborative operation are described.:1 Introduction 2 Robotic end effector in Assembly and Handling 3 Concept and Definition of Collaboration 4 Statement of the academic purpose and methodology 5 Guideline and Methodology for designing the Active Lightweight End-effector (ALE) for collaborative robots 6 Performance demand d4): multiplicity and versatility of end effector 7 A safety monitoring end effector (Adapter) for collaborative operations 8 A practical study of collaborative integration based on collaborative degree 9 Conclusion Appendix / Diese Arbeit liefert einen systematischen Leitfaden für die Bewertung, Integration und Gestaltung des kollaborierenden Endeffektorsystems in Verbindung mit kommerziell verfügbaren kollaborativen Robotern (Kobots).

In order to provide a sound economic basis for investment decisions to address this challenge, it is critical to assess the cost of these crashes. These estimates serve cost-benefit analysis inputs to facilitate a more efficient resources allocation for interventions to address the challenge posed by road crashes. South Africa has not been updating crash cost estimates on a regular basis, and those that were conducted used the much criticised human capital approach. Therefore, the available estimates could not be relied upon for planning purposes and comparison with the estimates of other countries. It is against this background that this study developed and illustrated the application of a hybrid framework for assessing the cost of road traffic crashes in South Africa. The framework uses the human capital approach and the willingness-to-pay approach in one study. Human capital approach cost estimates are needed to inform planning to maximize the national output, while the willingness-to-pay estimates are more suitable when the main concern is to inform interventions to increase social welfare by reducing injuries and fatalities. The willingness-to-pay approach uses the contingent valuation and the stated preference methods. A survey questionnaire with contingent valuation and stated preference questions was administered in two phases to a sample of 273 respondents within the transport industry. For the human capital approach, the cost estimates in the 2016 Cost of Crashes in South Africa report were adjusted for inflation using the 2017 rate of 5.3% to obtain 2017 cost estimates. This study revealed that the human capital approach underestimates the cost of road crashes. The study contributes to the body of knowledge by using the human capital approach and the willingness-to-pay approach in one study to illustrate the applicability of this hybrid/ combination within the South African context. Future research needs to replicate this study on a sample drawn from all nine provinces of South Africa, so that the cost estimates are representative of the country’s population. / Ukuphazamiseka komgwaqo kungenye yezingozi ezimbi kakhulu zokuhamba komgwaqo emhlabeni jikelele, ezimele inkinga enkulu yenhlalo nezomnotho ikakhulukazi emazweni asathuthuka njengeNingizimu Afrika.
