Constrained allocation problems with single-peaked preferences: An axiomatic analysis

We introduce a new class of problems that contains two existing classes: allocation problems with single-peaked preferences and bankruptcy problems. On this class, we analyze the implications of well-known properties such as Pareto optimality, strategy-proofness, resource-monotonicity, no-envy, equal treatment of equals, and two new properties we introduce, hierarchical no-envy and independence of nonbinding constraints. Unlike earlier literature, we consider rules that allow free-disposability. We present characterizations of a rule we introduce on this domain. We relate this rule to well-known rules on the aforementioned subdomains. Based on this relation, we present a characterization of a well-known bankruptcy rule called the constrained equal awards rule.

Control charts in practice

In the first issue of Significance , Roland Caulcutt suggested that a common feature of many successful companies is their development of a "management-by-fact" culture. He further suggested that such a culture requires that managers focus on processes, and that control charts be used at all levels throughout the organisation. In this follow-up article he explains how the various types of control chart are set up and used in practice.     

Exploring structure-effectiveness relationships in nonprofit arts organizations

The authors examined nineteen nonprofit performing arts organizations, investigating the distribution of influence among organizational members, the grouping of volunteers and staff in organizational structures, and the effectiveness of the organizations. The organizations' effectiveness was assessed using multiple performance indicators. The analysis revealed five groupings or configurations of influence, which correlated to the organizations exhibiting the highest and lowest levels of organizational effectiveness. The authors conclude that a variety of structures are associated with good performance but structural dysfunctions are associated with organizational failure, and that members' commitment to an organization's structure is an important element of success.     

Tukey’s M-estimator of the Poisson parameter with a special focus on small means

We treat robust M-estimators for independent and identically distributed Poisson data. We introduce modified Tukey M-estimators with bias correction and compare them to M-estimators based on the Huber function as well as to weighted likelihood and other estimators by simulation in case of clean data and data with outliers. In particular, we investigate the problem of combining robustness and high efficiencies at small Poisson means caused by the strong asymmetry of such Poisson distributions and propose a further estimator based on adaptive trimming. The advantages of the constructed estimators are illustrated by an application to smoothing count data with a time varying mean and level shifts.     

The Comparison of Grandparents’, Parents’, and Young People's Attitudes Toward Lesbians and Gay Men in Turkey

ABSTRACT

The present study aimed to compare attitudes toward lesbians and gay men across three generations in Turkey. Participants were 112 young people, 169 parents, and 125 grandparents. A total of 406 men and women were involved. The short form of Herek's (1998) the Attitudes Toward Lesbians and Gay Men Scale was used. MANOVAs and ANOVAs were used to analyze the data. Results showed the attitudinal differences toward gay and lesbian people across generations. Grandparents have the most negative attitudes, whereas parents have more negative attitudes than their children. When comparing attitudes of each generation across sex, we found that young women have more liberal attitudes toward gay men compared to all other groups. Discussion focuses on understanding the results within the unique cultural context of Turkey.     

How to Succeed in a Transnational Labor Market: Job Search and Wages among Hungarian,Slovak, and Czech Commuters in Austria

This paper deals with job search strategies and wages among cross‐border commuters residing in the Central European Region (CENTROPE). Our main aim is to investigate the role of social networks as constitutive for job searching and for successful labor market integration. We build upon a theoretical framework developed by Aguilera and Massey, reflecting on the nexus of social networks, job search methods, and related labor market outcomes. Methodologically, we use a new quantitative survey on the employment careers of cross‐border commuters residing in the regions of the Czech Republic, Slovakia, and Hungary bordering on Austria, conducted in the winter/spring of 2012/2013 (N = 2,573). Our results corroborate the hypothesis that human and social capital resources as well as labor market characteristics serve as key factors for job search and labor market integration among cross‐border commuters in the CENTROPE transnational labor market.     

Attitudes of social work students towards older people

Demographic ageing is a challenge for many countries. Even though Turkey has a relatively younger demographic composition, the proportion of the older people (65+) within the population is rapidly increasing. Within this framework, older people are becoming more important clients for both social work students and social workers in Turkey. This study aims to reveal the attitudes of social work students towards older people and determine the various factors that affect their views on older persons. In the scope of the project, Kogan's Attitude Towards Old People Scale was applied to 419 social work undergraduate students at a university located in Central Anatolia. The findings showed that social work students scored a mean of 130.96 and they generally had positive attitudes towards older people. The correlation between year of study, gender and age was not statistically significant. However, having lived mostly in urban areas was positively correlated with the mean Kogan scores and this finding was found to be statistically significant. Exposure to personal contact with older people at both the personal and professional levels was influential in shaping attitudes about the older people.     

Arbeitsmarktflexibilisierung und wachsende Niedriglohnbeschäftigung in Österreich

Western societies have experienced an increasing flexibilization and deregulation of their labour markets in the last decades. These developments led to an expansion of non-standard work as well as low-paid employment. Nevertheless, there has been little systematic research on flexibilization and low-paid employment in Austria. Against this background, we discuss the growth of low-wages in Austria and analyse which social groups are especially affected by lowpaid work, using data from EU-SILC as well as ECHP for the years 1996–2010. While we find that those with better qualification tend to be better protected against low-pay risks, our results underline that employees in personal services and hospitality industry as well as non-standard workers are increasingly exposed to low-pay risks in the last 15 years.
