The contributions of welfare typologies to international social work practices

This paper is concerned with the link between studies of welfare typologies and studies of international social work. Its objective is to show how welfare typologies could be used to strengthen the role of international social work practices to support international exchange of ideas on welfare issues. To meet this objective, three analytical tasks are implemented. The first task is to show that professional imperialism could weaken the potential of international social work practices to promote international exchange of ideas on welfare issues. The second task is to discuss the importance of welfare typologies in supporting the development of international social work by challenging professional imperialism. The third task is to discuss a research project on a defamilization typology. This project provides empirical evidence of the contributions made by welfare typologies to international social work practices.     

The Escalator: A Conveyor of Hong Kong's Culture

People believe that escalators provide a moreattractive, convenient, and physically less-demandingpedestrian access from one place to another. However, itdoes not mean all of us have to like them. Escalators do not only affect our perception of speed, butthe most important concern is that this urban objectalso influences our social relationships and humancommunication. Under the transmission of this urban object, we are treated as components (a what),rather than human beings (a who). Thus, this articlediscusses how modernist thinking affects how we see thisobject and ourselves, and examines the relative worth of it, in relation to the social lossincurred in the present or future. This article alsodiscusses how its presence in many of the daily settingsof urban life affects the culture, meaning and quality of life.Requests for reprints should be addressed SIU Kin Wai Michael, School of Design, The Hong Kong Polytechnic University, Hunghom, Kowloon, Hong Kong.     

Assessing Participation and Effectiveness of the Peer-Led Approach in Youth Sexual Health Education: Systematic Review and Meta-Analysis in More Developed Countries

Sexual health education for young people is crucial not only for development of norms but also for protection against vulnerabilities during this stage in life. Although several systematic reviews have examined the effectiveness of peer-led sex education, none have focused on the extent of peer participation. The purpose of this review was to evaluate peer-led sexual health education interventions in more developed countries (MDCs). Electronic and manual searches across five social science, education, and medical databases were conducted. Fifteen articles were selected in total. Most (10 of 15) studies gave low or no responsibility to peers. The majority of articles found improvements in sexual health knowledge (13 of 14) and attitudes (11 of 15) at postintervention stages. Two studies showed improved self-efficacy, and three showed behavioral changes. A preliminary synthesis of effectiveness and level of participation was done. Meta-analysis revealed a large effect on knowledge change (Hedges’ g = 0.84, 95% confidence interval [CI]: 0.43 to 1.25) and a medium effect on attitude change (Hedges’ g = 0.49, 95% CI: 0.19 to 0.80). Peer-led interventions could be a powerful tool. This review shows that this approach is effective in changing knowledge and attitudes but not behaviors. Further research and action are needed to understand optimal implementation.     

Decalage in Infants' Search for Mothers Versus Toys Demonstrated With a Delayed Response Task

Thirty‐one infants, 7 to 14 months of age, were tested on object and mother permanence using a delayed response task (Diamond, 1985), in which a delay period is enforced before infants are allowed to search for hidden objects. Infants were tested in 2 separate conditions in which they searched for their mothers and a large toy, both of which were hidden under curtained tables. The delay period before search was allowed was incremented after each successful trial until infants either failed to search or searched in the wrong location. Infants were scored for the maximum delay preceding a successful search. The results from 17 infants showed that infants were able to withstand significantly longer delays before successful search for the mother than for the toy. These results support previous studies showing that mother permanence precedes object permanence in infants older than 8 months.     

School‐to‐Work Transition of Career and Technical Education Graduates

This study analyzed the career development of career and technical education (CTE) high school graduates during their school‐to‐work transition, specifically their adaptability in the face of barriers. Forty graduates (22 men, 18 women) from working‐class backgrounds participated in baseline surveys at graduation and phenomenological interviews 1 year postgraduation. Primary themes were job loss altered career plans, whereas relevant jobs propelled career development; limited access to college constrained options, whereas college experience expanded options; graduates experienced the loss of education‐related support, and CTE served as a backup plan. Teachers and school counselors emphasized organizational barriers including limited staffing for upper level math courses and inconsistent workplace partnerships.     

Bayesian adaptive dose‐escalation designs for simultaneously estimating the optimal and maximum safe dose based on safety and efficacy

The main purpose of dose‐escalation trials is to identify the dose(s) that is/are safe and efficacious for further investigations in later studies. In this paper, we introduce dose‐escalation designs that incorporate both the dose‐limiting events and dose‐limiting toxicities (DLTs) and indicative responses of efficacy into the procedure. A flexible nonparametric model is used for modelling the continuous efficacy responses while a logistic model is used for the binary DLTs. Escalation decisions are based on the combination of the probabilities of DLTs and expected efficacy through a gain function. On the basis of this setup, we then introduce 2 types of Bayesian adaptive dose‐escalation strategies. The first type of procedures, called “single objective,” aims to identify and recommend a single dose, either the maximum tolerated dose, the highest dose that is considered as safe, or the optimal dose, a safe dose that gives optimum benefit risk. The second type, called “dual objective,” aims to jointly estimate both the maximum tolerated dose and the optimal dose accurately. The recommended doses obtained under these dose‐escalation procedures provide information about the safety and efficacy profile of the novel drug to facilitate later studies. We evaluate different strategies via simulations based on an example constructed from a real trial on patients with type 2 diabetes, and the use of stopping rules is assessed. We find that the nonparametric model estimates the efficacy responses well for different underlying true shapes. The dual‐objective designs give better results in terms of identifying the 2 real target doses compared to the single‐objective designs.

Status and welfare under monopolistic competition

This article departs from the traditional welfare analysis of social status seeking by incorporating scale economies, product differentiation, and monopolistic competition into a model. I argue that social status seeking could be welfare improving rather than the usual conclusion that social status seeking is welfare-reducing, under some assumptions that are not particularly strong. Market distortions of the quantity–variety and consumption–leisure trade-off may be corrected by social status seeking. Since modern societies are arguably closer to monopolistic competition than perfect competition, we may also need to rethink the long-held belief that the welfare effects caused by social status seeking are usually negative.

A bivariate density estimation method based on level crossings

This article introduces a method of nonparametric bivariate density estimation based on a bivariate sample level crossing function, which leads to the construction of a bivariate level crossing empirical distribution function (BLCEDF). An efficiency function for this BLCEDF relative to the classical empirical distribution function (EDF), is derived. The BLCEDF gives more efficient estimates than the EDF in the tails of any underlying continuous distribution, for both small and large sample sizes. On the basis of BLCEDF we define a bivariate level crossing kernel density estimator (BLCKDE) and study its properties. We apply the BLCEDF and BLCKDE for various distributions and provide results of simulations that confirm the theoretical properties. A real-world example is given.
