The Attitudes of Social Work Students Toward End-of-Life Care Planning

This study examined the attitudes of social work students toward end-of-life care planning, as well as their degree of willingness to engage in this area of social work practice. Factors associated with their attitudes were measured through structured surveys completed by 102 social work students (N = 102) at a school of social work in the southeast. Results indicated that these social work students tended to have positive attitudes toward end-of-life care planning in general. Moreover, these attitudes were positively associated with preference for pain relief treatment, higher levels of comfort when discussing death, more emphasis on self-determination, and apprehension of conflicts of self-determination. The results of this study underscored the increased societal need for recognition of personal preferences in end-of-life care, higher levels of comfort when discussing death, and an increased commitment of social workers' to maintaining the ethical principle of the client's right to self-determination in end-of-life planning. While this is not surprising, it points to a continuing need to re-assess where the field stands in its preparation of social work professionals who will work closely with people who are dying and their families.     

A graphical evaluation of logistic ridge estimator in mixture experiments

In comparison to other experimental studies, multicollinearity appears frequently in mixture experiments, a special study area of response surface methodology, due to the constraints on the components composing the mixture. In the analysis of mixture experiments by using a special generalized linear model, logistic regression model, multicollinearity causes precision problems in the maximum-likelihood logistic regression estimate. Therefore, effects due to multicollinearity can be reduced to a certain extent by using alternative approaches. One of these approaches is to use biased estimators for the estimation of the coefficients. In this paper, we suggest the use of logistic ridge regression (RR) estimator in the cases where there is multicollinearity during the analysis of mixture experiments using logistic regression. Also, for the selection of the biasing parameter, we use fraction of design space plots for evaluating the effect of the logistic RR estimator with respect to the scaled mean squared error of prediction. The suggested graphical approaches are illustrated on the tumor incidence data set.     

Estimate for the Finite-time Ruin Probability in the Discrete-time Risk Model with Insurance and Financial Risks

In this article, we consider a discrete-time risk model with insurance and financial risks. We derive some refinements of a general asymptotic formula for the finite-time ruin probability under the assumptions that the net losses follow a common distribution in the intersection between the subexponential class and the Gumbel maximum domain of attraction, and the stochastic discount factors of the risky asset have a common distribution with extended regular variation. The obtained asymptotic upper and lower bounds are transparent and computable.     

Cycles of Adaptive Strategies Over the Life Course

An increasing number of Australia’s ageing population are aging with long-term physical impairments. This study explored the life experiences of this group using a qualitative approach. In-depth interviews were conducted with 10 disabled Victorians, aged between 51 and 84 years, and an inductive thematic analysis undertaken. A relationship was found between the adaptive strategies that participants developed as they moved through life phases and the impairment stages. The implications of the emergence of a cyclical process of adaptation across the life course. and particularly in respect of aging, delivery of aged-care services and social workers in this sector are discussed.     

Nonparametric Kernel Methods with Errors‐in‐Variables: Constructing Estimators,Computing them,and Avoiding Common Mistakes

Estimating a curve nonparametrically from data measured with error is a difficult problem that has been studied by many authors. Constructing a consistent estimator in this context can sometimes be quite challenging, and in this paper we review some of the tools that have been developed in the literature for kernel‐based approaches, founded on the Fourier transform and a more general unbiased score technique. We use those tools to rederive some of the existing nonparametric density and regression estimators for data contaminated by classical or Berkson errors, and discuss how to compute these estimators in practice. We also review some mistakes made by those working in the area, and highlight a number of problems with an existing R package decon .

最优货币数量与消费攀比

本文在一个随机技术冲击驱动的模型经济中,将消费攀比引入个体效用函数,研究了个体间存在消费攀比时的政府最优货币政策问题。本文发现,当个体之间存在消费攀比现象时,政府的最优货币政策是一种反周期的总需求管理政策当经济萎缩时,政府通过降低名义利率来刺激经济;当经济过热时,政府选择紧缩性的货币政策来使经济冷却。该结果类似于Keynes理论中的总需求管理政策,但本文是在一个最大化个体效用的一般均衡框架中得到的,并且产生的机制也不相同。另外本文结果表明,个体之间的消费攀比产生了外部效应,为抵消外部效应所带来的效率丢失必须引入新的扭曲税,此时最优名义利率不为零,从而Friedman的最优货币数量法则需要修正。

Sexual Orientation and Quality of Life Among University Students from Cuba,Norway, India,and South Africa

This article explores quality-of-life aspects among gay, lesbian, bisexual, and straight male and female students in Havana (Cuba), Troms? (Norway), Hisar (India), and Cape Town (South Africa). In the period 2004–2005, a questionnaire survey on sexuality, happiness, and life satisfaction was undertaken among 339 students from the University of Havana, 144 students from the University of Troms?, 200 students from Guru Jambheswar University, and 189 students from the University of the Western Cape. The majority of the participants were straight and, in Hisar and Cape Town, few of those who regarded themselves as gay/lesbian/bisexual had engaged in sex with a person of the same gender. In all cities, straight men and women scored higher than gay, lesbian, and bisexual persons on the quality-of-life measures. Quality of life among gay/bisexual men and lesbian/bisexual women was higher in cultures with accepting attitudes toward homosexuality than in cultures with restrictive attitudes.
