What makes age diverse teams effective? Results from a six-year research program

Based on a new model of productivity in age diverse tams, findings from a six-year research program are reported in which data from more than 745 natural teams with 8,848 employees in three different fields (car production, administrative work, financial services) were collected. Moreover, central assumptions of this model were tested with a representative survey of the German workforce (N = 2,000). Results support both significant advantages and disadvantages for age-mixed teams. Based on the findings, the following preconditions for the effectiveness of age diverse teams are identified: high task complexity, low salience and high appreciation of age diversity, a positive team climate, low age-discrimination, ergonomic design of work places, and the use of age differentiated leadership. Based on these insights, we developed a new training for supervisors, which addresses the aforementioned aspects and seeks to improve team performance and health of team members. It was found that the training reduces age stereotypes, team conflicts and enhances innovation. Thus, we can conclude that effective interventions for a successful integration of elderly employees in work groups are available and that combinations of measures that address ergonomic design issues, team composition and leadership are to be strongly recommended for practice.     

Efficiency of consumer intertemporal choice under life cycle cost conditions

Many decisions made by consumers are intertemporal. Life cycle cost (LCC) conditions represent a specific type of intertemporal decisions, typically referring to items involving two cost components: present purchase price and future maintenance costs. This paper presents a conceptual framework for analyzing consumer LCC decision making. Within this framework the notion of choice efficiency is highlighted. The main contribution of the study is the direct estimation of consumers’ choice efficiency, as compared to previous studies that estimate only consumers’ implicit discount rates. Effects of situational and personal variables on efficiency of choice are estimated by means of a series of manipulated choice settings. The main empirical findings show situational effects of monetary size, type of object and time horizon. Additional findings show the effect of personal variables such as gender, marital status and education.     

Situational Factors Related to Childhood Sexual Abuse in the Orthodox Jewish Community Among Adult and Juvenile Offenders

In recent years, increasing attention has been paid to situational factors associated with childhood sexual abuse (CSA) to explain incidence of CSA, as well as to provide potential targets for prevention efforts. However, very few studies have examined situational factors associated with juvenile perpetration, despite juveniles composing a substantial proportion of offenders. In addition, no studies to our knowledge have applied a situational framework to CSA research in the Orthodox Jewish community (OJC). In the present study, we obtained data from therapists regarding 80 victims of CSA in the OJC from both the United States and Israel. We hypothesized that (a) more abusers’ first perpetration would be between ages 12 and 17 than between any other age range, which corresponds to increased sexual urges, as well as increased unsupervised access to minors; (b) among juvenile offenders, the time of day of the abuse would depend on the relationship of the offender to the victim; and (c) age of the victim and grooming strategies would be associated with the frequency of abuse. Our first two hypotheses were confirmed, and our third hypothesis was partially confirmed, as younger victims tended to have higher frequency of abuse. Additionally, we discuss possible implications of significant correlations found during exploratory analyses. Our results generally support the importance of considering culturally specific situational factors when studying or developing prevention efforts for CSA.     

The Pro‐Elderly Bias of Social Policies in Israel: A Historical‐Institutional Account

Accelerated population ageing and high voting turnout rates among elderly voters in recent decades have led many social scientists to predict increasing pro‐elderly biases in the social policies of mature welfare states. This article investigates and empirically estimates the evolving age orientation of social policies in Israel, which is a comparatively young society that has nevertheless aged significantly since independence in 1948. We present a historical and qualitative overview of the development of policy efforts towards different age groups and develop an Elderly/Non‐elderly Spending Ratio at four points in time between 1975 and 2005. We argue that in its first five decades, the Israeli welfare state uniquely combined a broadly universalistic and citizenship‐based outlook with a number of significant particularistic spending biases towards specific subgroups. But from the second half of the 1990s onwards, the pro‐elderly policy bias of the Israeli welfare state has strongly increased. These findings support Lynch's thesis for 21 OECD countries, which posits that a shift from a universal to a more occupationally based institutional model of welfare will result in a higher pro‐elderly bias of social spending.
