Navigating the ethical maze in disability research: ethical contestations in an African context

Despite changes in how disability is viewed, ethical requirements for disability research have hardly changed. Some ethical clearance procedures, processes and practices still consider persons with disabilities as not able, creating unease among researchers and research participants with disabilities themselves. This paper considers five ethical contestations arising from research in the area of disability in an African context: positionality, vulnerability, signed consent, anonymity, and research committee composition. We argue that ethical requirements in practice are still largely based on a medical model of disability and propose that culturally sensitive social and human rights models should influence disability research ethics.     

THEORIES OF RISK: TESTING INVESTOR BEHAVIOR ON THE TAIWAN STOCK AND STOCK INDEX FUTURES MARKETS

This article considers four utility functions—concave, convex, S‐shaped, and reverse S‐shaped—to analyze the behavior of different types of investors on the Taiwan stock index and its corresponding index futures. Using stochastic dominance (SD) rules, we show that the existence of all four investor types is plausible. Risk averters prefer spot to futures, whereas risk seekers prefer futures to spot. Investors with S‐shaped utility functions prefer spot (futures) to futures (spot) when markets move upward (downward). Investors with reverse S‐shaped utility functions prefer futures (spot) to spot (futures) when markets move upward (downward). We show that both spot and futures markets can exist when only risk averters are present, but futures can dominate spot only if there is some risk‐seeking behavior. These results are robust with respect to subperiods, spot returns including dividends, and diversification. (JEL C14, G12, G15)     

Israel's military public diplomacy evolution: Historical and conceptual dimensions

This study provides an historical overview of the IDF Spokesperson’s Unit (ISU) from the early years of the State of Israel until 2009. Analyzing five periods during which the ISU played a key role in Israel's public diplomacy, this research sheds light on the challenges the ISU faced in different periods and circumstances and examines how the ISU tried to modify its methods and actions in response to geopolitical changes and media development, albeit not always successfully. The study suggests better understanding the adaptation process by applying a three-layer framework for analysis: the tactical layer, the strategic layer and the perceptional layer. The findings of this work demonstrate that in adapting to new circumstances, the ISU focused mainly on the tactical response level, with the result that it did not undertake any review or debate over the need for deeper perceptional changes in ISU policies.     

Statistical Analysis of Coins Lost in Circulation

The loss rate of coins in the Israeli pound (IL) series issued in Israel in 1960–1979 is estimated, and the connection between it and the characteristics of the coins is examined. A lifetime model with time-dependent hazard rate and an estimation procedure for the model parameters are presented. The estimates are then used to forecast the number of coins surviving in circulation and the median lifetime of different denominations. The data are random samples drawn from the coins in circulation at a point in time, the sampled coins being sorted by date of issue.     

The differential gender effect of internalized racism on abdominal obesity in KwaZulu-Natal,South Africa

This research examined the effect of a psychosocial variable, internalized racism, on abdominal obesity, as measured by waist circumference. Results show that the effect of internalized racism on waist circumference persists net of other controls among women, but not among men. Also, among women who had high levels of internalized racism and high educational levels, a positive relationship to abdominal obesity is evident despite the tendency of education to be protective of abdominal obesity. This study supports other research findings that internalized racism is related to waist circumference among adult women but not among men in Western Hemisphere blacks. It also supports past research findings of a gendered reaction to psychosocial stress. It also illustrates that this relationship occurs on the continent of Africa, an area where research on this phenomenon is scarce.     

Accessibility to micro-finance services by people with disabilities in Bushenyi District,Uganda

The Poverty Reduction Strategy of the Ugandan Government identified provision of microfinance as one of its interventions. Despite the known connection between poverty and people with disabilities, it remains unclear to what extent this intervention includes or accommodates them. This study seeks to gain a better understanding of how people with physical and sensory disabilities access existing microfinance services in the Bushenyi District of Uganda. Qualitative and quantitative methodologies are used. The findings suggest that people with disabilities are not necessarily denied access to microfinance if they meet the desired requirements. These relate to adequate savings or collateral and perceived trustworthiness. These are seen to be key determinants of success and can be linked to impaired functioning relating to limited mobility, distance, poorer access to information and disabled people’s own negative attitudes. Increasing access and utilization of microfinance services by people with disabilities requires formulation of financial policies that accord them special consideration. At the same time, improvement is needed in the knowledge, attitudes and skills of the people with disabilities themselves and also microfinance providers.     

Environmental Vulnerability in Public Perceptions and Attitudes: The Case of Israel's Urban Centers

Objective. This article investigates how urban environmental vulnerability to hazards reflects in the perceptions and attitudes of the public in three major cities in Israel: Jerusalem, Tel Aviv, and Haifa. Our central argument is that the differences between the residents' perceptions and attitudes toward environmental issues are related mostly to the actual hazard levels of their communities, whereas individual differences in socioeconomic characteristics are of lesser importance in this regard. Methods. The research was based on survey data of representative samples of the adult residents in the three cities. The differences in attitudes and perceptions among the three samples were statistically assessed by means of analysis of variance. Results. We found relatively strong and consistent relationships between actual environmental vulnerability to hazards in the three cities and their residents' attitudes toward environmental issues. The relationships with socioeconomic characteristics, such as education and income, were considerably weaker and less consistent. Conclusions. The results of this research indicate that environmental concern is not exclusive to groups and individuals characterized by postmaterialist values. Rather, the urban public in general is responsive to the environmental vulnerability of its community. This conclusion supports the argument that attitudes toward the environment are mainly affected by instrumental considerations of objective environmental problems rather than by subjective values.
