Tournaments and unfair treatment

This paper introduces the negative feelings associated with the perception of being unfairly treated into a tournament model and examines the impact of these perceptions on workers’ efforts and their willingness to work overtime. The effect of unfair treatment on workers’ behavior is ambiguous in the model in that two countervailing effects arise: a negative impulsive effect and a positive strategic effect. The impulsive effect implies that workers react to the perception of being unfairly treated by reducing their level of effort. The strategic effect implies that workers raise this level in order to improve their career opportunities and thereby avoid feeling even more unfairly treated in the future. An empirical test of the model using survey data from a Swedish municipal utility shows that the overall effect is negative. This suggests that employers should consider the negative impulsive effect of unfair treatment on effort and overtime when designing contracts and determining promotions.     

社会主义与机会平等——约翰·罗默的正义理论

约翰·罗默运用分析方法及模型构建、博弈论等方法,界定了撤出式博弈的一般剥削观以及社会必要剥削等概念。出于对作为剥削根源的财产关系的重视,罗默转向分配正义研究,并提出社会主义的本质在于机会平等。罗默的机会平等主张根据外部不可控因素将社会成员划分为不同类型,接受每一类型内部成员的收入不平等,同时实现不同类型间相同百分位数者的收入平等,使努力程度相等而非努力数量相等的人获得相等回报。以机会平等为目标,罗默还设计了以息票为主要特色的证券市场社会主义方案,致力于兼顾平等与效率,使公民分享经济利润的机会平等,同时避免财富继承的代际不平等。罗默的正义理论和研究方法别具特色,为坚持和发展马克思主义提供了正反两方面的借鉴意义。     

Statistical considerations in clinical trial design with event-free survival as the primary efficacy endpoint

In late-phase confirmatory clinical trials in the oncology field, time-to-event (TTE) endpoints are commonly used as primary endpoints for establishing the efficacy of investigational therapies. Among these TTE endpoints, overall survival (OS) is always considered as the gold standard. However, OS data can take years to mature, and its use for measurement of efficacy can be confounded by the use of post-treatment rescue therapies or supportive care. Therefore, to accelerate the development process and better characterize the treatment effect of new investigational therapies, other TTE endpoints such as progression-free survival and event-free survival (EFS) are applied as primary efficacy endpoints in some confirmatory trials, either as a surrogate for OS or as a direct measure of clinical benefits. For evaluating novel treatments for acute myeloid leukemia, EFS has been gradually recognized as a direct measure of clinical benefits. However, the application of an EFS endpoint is still controversial mainly due to the debate surrounding definition of treatment failure (TF) events. In this article, we investigate the EFS endpoint with the most conservative definition for the timing of TF, which is Day 1 since randomization. Specifically, the corresponding non-proportional hazard pattern of the EFS endpoint is investigated with both analytical and numerical approaches.     

Heterogeneity in treatment effects across diverse populations

Differences in patient characteristics, including age, sex, and race influence the safety and effectiveness of drugs, biologic products, and medical devices. Here we provide a summary of the topics discussed during the opening panel at the 2018 Johns Hopkins Center for Excellence in Regulatory Science and Innovation symposium on Assessing and Communicating Heterogeneity of Treatment Effects for Patient Subpopulations: Challenges and Opportunities. The goal of this session was to provide a brief overview of FDA-regulated therapeutics, including drugs, biologics and medical devices, and some of the major sources of heterogeneity of treatment effects (HTE) related to patient demographics, such as age, sex and race. The panel discussed the US Food and Drug Administration's role in reviewing and regulating drugs, devices, and biologic products and the challenges associated with ensuring that diverse patient populations benefit from these therapeutics. Ultimately, ensuring diverse demographic inclusion in clinical trials, and designing basic and clinical research studies to account for the intended patient population's age, sex, race, and genetic factors among other characteristics, will lead to better, safer therapies for diverse patient populations.     

Nonshared Environment Research

SUMMARY

This review focuses on conceptualizations of nonshared environment and on four areas of research that should be targeted for future growth. It is argued that there are at least two different approaches to the study of nonshared environment. “Experience-oriented” researchers center on sibling differential experiences in the family and their role in children's development. “Outcome-oriented” investigators focus on the search for environmental origins of individual differences in outcomes. Turkheimer and Waldron's (2000) concept of objective versus effective nonshared environment and Reiss and colleagues' (2000) notion of single-system versus multi-system nonshared environment processes are also discussed. Four topics for future research are outlined: (1) age-related changes and development; (2) the role of the self; (3) the role of context; and (4) the importance of extrafamilial experiences. More work in these areas will lead to useful theories of how nonshared environment processes are linked to sibling and individual differences in behavioral development and adjustment.     

A Postmodern Critique of Societal Discourses of Male Violence in Interpersonal Family Relationships: A Balancing Act for Social Work

In recent years, treatments of family violence have tended to be built around conventional discourses suggesting that men are major initiators in instances of interpersonal violence. Utilizing a postmodernist analysis, we assess societal discourses that continue to give life to this narrow conceptualization of interpersonal violence. We also examine literature suggesting that both men and women resort to violence to resolve relationship difficulties and suggest that a more holistic and inclusive approach to understanding interpersonal violence is critical for social workers committed to social justice and a balanced understanding of the contextual nature of human problems.     

Healthy Barbs: Activism Confronts Mortality

Barbara Brenner, JD, was the Executive Director of Breast Cancer Action (BCA) from 1995–2010. Before that, she was a longtime activist in the anti-war movement and an attorney who, for most of her career, practiced public policy law. After she was diagnosed with breast cancer in 1993 at the age of 41, she took the helm of BCA. Under her leadership, the organization moved into a position of national advocacy—demanding research on the causes and prevention of breast cancer, including the role of industrial pollutants. Barbara started the “Think Before You Pink” campaign, encouraging people to question whether companies that display pink ribbons actually produce products that harm women's health or generate any funds to fight breast cancer. Her blog, “Healthy Barbs,” challenged readers to critique routine healthcare practices and policies. Barbara received numerous awards, including a Jefferson Award for Public Service in 2007, the Smith College Medal in 2012, and the ACLU-Northern California's Lola Hanzel Courageous Advocacy Award in 2012. Barbara had a recurrence of breast cancer in 1996. She died of complications associated with amyotrophic lateral sclerosis, ALS, on May 10, 2013.     

Symptoms of Eating Disorders Among Females in Drug Addiction Treatment

The aim of this study is to measure and describe symptoms of eating disorders among females in treatment for drug addiction in Norway. Previous clinical and epidemiological studies have revealed coprevalence between eating disorders and substance use or abuse. However, few studies have measured eating disorders in drug-using samples and even fewer within the context of drug treatment. In this study, 29 females with drug use disorder in residential treatment were tested with the Eating Disorder Inventory–2. A subgroup of 9 females (31%) with significant symptoms of eating disorders was identified. The characteristics of this group and possible clinical consequences are discussed.     

Promoting Gender Equality without a Gender Perspective: Problem Representations of Equal Pay in Finland

The current locus of promoting equal pay in Finland is the workplace. Legal instruments, like gender equality planning and its pay surveys, are to be implemented in workplaces. This development raises important questions about the central role of the local trade union representatives as promoters of equal pay. This article analyses how local trade union representatives construct the problem of unequal pay and their role in narrowing the gender pay gap and their possible agonistic adversaries in negotiations on equal pay. Different problem representations concerning equal pay are analysed and evaluated on the basis of their potential to fracture the gender‐blind wage bargaining culture and ability to cash in on the promises made towards narrowing the gender pay gap.     

Theoretical Factors Influencing Adolescent Sexual Behavior: Evidence from a Rural Sample Living in Poverty

ABSTRACT

This study of 414 adolescents who resided in rural Arkansas families receiving AFDC was designed to investigate what theoretical factors predicted frequency of sexual intercourse in the past year prior to the study and number of lifetime sexual partners among males and females. Multivariate analyses indicated that elements of bonding were important to the sexual behavior of females, but not males. On the other hand, feelings of frustration influenced male sexual behavior only. The number of sex partners was increased by associations with sexually active peers for both genders while only females made excuses. The only factor which was associated with both sexual behaviors among both genders was having sex to have a baby to love or to draw a partner closer. The family social work implications of these findings were discussed.
