Disaster Work in China: Tasks and Competences for Social Workers

This paper presents the results of a survey on the social work tasks and competences required in disaster management in China. The survey questionnaire was administered at two training workshops held in Sichuan in July and September 2010. The number of survey respondents was 67. The results of tasks analysis indicated perceptions of a division of labor among government officials, social workers, and other disaster responders. The survey results also showed that identifying and addressing the special needs of vulnerable populations required moderate to high levels of competency. Overall, the results should be seen as preliminary and used as the basis for ongoing dialogue with social work educators and social workers about what is required in disaster training.     

A stochastic programming model for production planning of perishable products with postponement

This study addresses the production planning problem for perishable products, in which the cost and shortage of products are minimised subject to a set of constraints such as warehouse space, labour working time and machine time. Using the concept of postponement, the production process for perishable products is differentiated into two phases to better utilise the resources. A two-stage stochastic programming with recourse model is developed to determine the production loading plan with uncertain demand and parameters. A set of data from a toy company shows the benefits of the postponement strategy: these include lower total cost and higher utilisation of resources. The impact of unit shortage cost under different probability distribution of economic scenarios on the total cost is analyzed. Comparative analysis of solutions with and without postponement strategies is also performed.     

Should we be very cautious or extremely cautious on measures that may involve our destruction?

For decisions (e.g. nuclear power development, environmental protection, genetic engineering) that may affect the probabilities of the continued survival of the human race, whether we should be very cautious or extremely cautious (defined as refusing to undertake anything that may reduce our survival probabilities) depends on whether our expected welfare is finite or infinite. If it is infinite, a paradox arises in the trade-off between our own expected welfare and that of future generations, since a small fraction (probability change) of infinity is still infinite. However, limitations on population size and average welfare suggest a finite expected welfare but the possibility of transforming our own selves perhaps by genetic engineering increases our expected welfare tremendously but still finite.The author acknowledges the helpful comments of John Broome and Maurice Salles.     

A case for cardinal utility and non-arbitrary choice of commodity units

With preference changes, cardinal utility is indispensable. For any necessity good, there exists an intermediate consumption level at which a change in preference intensity has no effect on utility, below/above which an increase in preference intensity decreases/increases utility. This is supported by an indicative empirical survey. At the intermediate consumption level, the utility from the relevant good is zero. For a Cobb-Douglas utility function, this intermediate consumption level equals one, making the choice of the unit of measurement non-arbitrary.We are grateful to a referee for some helpful comments     

Quality of Life in Older Adults: Benefits from Caring Services in Hong Kong

Many older adults are in need of care. Therefore, older people would generally benefit from the use of caring services, notably including home care, residential care, nursing, and medical services. The contributory factors underlying caring services tend to be a caring perspective that aspires to sustain older people’s social relationships and real-life involvement. To gauge the benefits from various social and health services, the present study relies on a large-scale survey of 3000 older adults in Hong Kong, using quality of life as a criterion. Results showed that an older adult who had used (ordinary or enhanced) home care services for a longer time turned out to have appreciably more improvement in quality of life. Besides, those who joined an interest group more frequently were higher in quality of life, including the health domain. On the other hand, frequent use of medical and meal-to-home services were signals that reflected problems detrimental to the older user’s quality of life. Despite this, the quality of clinics or hospitals, as perceived by the older adult, was the most beneficial. As such, caring services that foster older adults’ interests, cater to their health care needs, and embody quality can have principal contribution to their users’ quality of life.     

Medicaid State Plan personal care services: trends in programs and policies

Policymakers face mounting pressures from consumer demand and the 1999 Olmstead Supreme Court decision to extend formal (paid) programs that deliver personal care to the elderly, chronically ill, and disabled. Despite this, very little is known about the largest program that delivers personal care: the Medicaid State Plan personal care services (PCS) optional benefit. This paper presents the latest available national program (participant and expenditure) trend data (1999-2002) on the Medicaid PCS benefit and findings from a national survey of eligibility and cost control policies in use on the program. The program trends show that, over the study period, the number of states providing the Medicaid PCS benefit grew by four (from 26 to 30), and national program participation, adjusted for population growth, increased by 27%. However, inflation-adjusted program expenditures per participant declined by 3% between 1999 and 2002. Findings from the policy survey reveal that between 1999 and 2002 there was a marked decline in the range of services provided, and by 2004, almost half the programs operated a cap on the hours of services provided.     

Testing for monotonic trend in time series based on resampling methods

In this paper, we propose several tests for monotonic trend based on the Brillinger's test statistic (1989, Biometrika, 76, 23–30). When there are highly correlated residuals or short record lengths, Brillinger's test procedure tends to have significance level much higher than the nominal level. It is found that this could be related to the discrepancy between the empirical distribution of the test statistic and the asymptotic normal distribution. Hence, in this paper, we propose three bootstrap-based procedures based on the Brillinger's test statistic to test for monotonic trend. The performance of the proposed test procedures is evaluated through an extensive Monte Carlo simulation study, and is compared to other trend test procedures in the literature. It is shown that the proposed bootstrap-based Brillinger test procedures can well control the significance levels and provide satisfactory power performance in testing the monotonic trend under different scenarios.     

The family exclusion order as a harm-minimisation measure for casino gambling: the case of Singapore

Singapore is one of the first jurisdictions in the world that has implemented a harm minimization model based on third party exclusion known as the Family Exclusion Order (FEO). Unlike other forms of third party exclusion practiced in other countries, family members in Singapore are able to apply for FEOs to prevent a gambler from entering the casinos, if the family has experienced harm caused by his/her gambling. In this study, 105 applicants for the FEO were sampled from all successful FEOs granted within a five-year period. Using a qualitative approach, this study attempts to illuminate the intricate issues experienced by family members that provided the impetus for them to apply for the FEO. While the extant literature posits self-exclusion as a superior tool of restraint as it involves the gambler’s personal motivation to curb gambling, this paper reports initial evidence of benefits resulting from family-imposed restraints from the perspective of family members. In particular, positive ratings of the FEO stemmed from a sense of relief experienced by mother and wife applicants. Possible reasons behind these positive outcomes are explicated using intrinsic motivation theory, with sensitivity to gender relations within the family.     

Naloxone administration for suspected opioid overdose: An expanded scope of practice by a basic life support collegiate-based emergency medical services agency

Opioid abuse is a growing and significant public health concern in the United States. Naloxone is an opioid antagonist that can rapidly reverse the respiratory depression associated with opioid toxicity. Georgetown University's collegiate-based emergency medical services (EMS) agency recently adopted a protocol, allowing providers to administer intranasal naloxone for patients with suspected opioid overdose. While normally not within the scope of practice of basic life support prehospital agencies, the recognition of an increasing epidemic of opioid abuse has led many states, including the District of Columbia, to expand access to naloxone for prehospital providers of all levels of training. In particular, intranasal naloxone is a method of administering this medication that potentially avoids needlestick injuries among EMS providers. Universities with collegiate-based EMS agencies are well positioned to provide life-saving treatments for patients acutely ill from opioid overdose.
