The Helpfulness of Holistic Arts–Based Group Work with Children Living in Foster Care

This article discusses practice-based research that is exploring the helpfulness of holistic arts–based group work for the development of self-awareness and self-esteem in children living in foster care. The group program is arts based and encourages children to explore their beliefs, feelings, and behaviors. Examples of group exercises are provided, challenges in developing this group program are discussed, and qualitative research findings are presented, which are based on the analysis of fifteen 6-week groups. Findings indicate that children learned new skills, improved coping abilities, connected with feelings, and felt more positive. Practitioners are encouraged to consider how arts-based group work can help children in care.     

The Emergence of the Responsible Conduct of Research (RCR) in PHS Policy and Practice

The Responsible Conduct of Research (RCR) is now an established academic field taught at virtually every major American research university and generates a growing volume of research and pedagogical literature. Paradoxically, it is a field without a consensually agreed upon definition, goals, foundational theories, research agenda, and pedagogical methodology. It has been suggested that RCR as currently being taught is ineffective in preventing misconduct and improving the quality of research. The following short history of RCR, focused mainly on Federal policy and practice, explains how this curious state of affairs developed and persists and concludes with some suggestions for the future of RCR instruction.     

我是茫茫“职海”里一条搁浅的“鱼”

我是今年回国的留学生。看了《我遇上了“抠门”老板》中讲的老板的事,觉得还真是那么回事,我的台资老板也是这样的……本以为自己是美国MPA,在国内找个称心的工作不成问题,没想到回来不到半年,非但没有找到好工作,还遇上了“抠门”老板。现在我的梦想完全破灭,连自信心都快湮没了,感觉就像一条在岸上搁浅的鱼……     

Unintended Consequences of Land Rights Reform: The Case of the 1998 Uganda Land Act

Empirical studies of land rights privatisation have tended to underemphasise the unintended impacts of land rights reform relative to establishing whether the predicted impacts have occurred. This article, in reviewing some of the unintended consequences of the 1998 Uganda Land Act, draws attention to ways in which intended impacts may be undercut by lack of both consultation and foresight in anticipating responses to new legal provisions and by lack of adequate resourcing of the reform process. It also recognises that unintended outcomes may sometimes reflect appropriate adaptations of legal provisions at the local level, and briefly considers what light the Ugandan experience can throw on recent proposals for Normalisation of informal property rights in the Third World.     

The Differential Effects of Transformational Leadership on Multiple Identifications at Work: A Meta‐analytic Model

Employees’ identifications are a valuable asset for modern organizations, and identification research has stressed the necessity to distinguish identifications according to their focus (i.e. organizational, team, or leader identification). Interestingly, transformational leadership (TFL) has been proposed to unfold its effects by transforming followers’ identifications and could thus be a powerful way to actively manage identification. However, it remains unclear whether TFL affects identifications with different foci similarly or whether it predominantly influences a specific focus. To resolve this puzzle, the authors conducted a meta‐analysis (k = 73; N = 20,543) and found that TFL (and each TFL sub‐dimension) is more strongly associated with leader identification than with organizational identification or team identification. By presenting a comprehensive model of TFL's effects on identifications, we show that leader identification mediates the relationships between TFL and collective identifications (i.e. organizational identification or team identification), illustrating that relational identification plays a crucial role in subsequently shaping collective identifications. Implications for research and practice are discussed.     

How Leaders Affect Followers’ Work Engagement and Performance: Integrating Leader−Member Exchange and Crossover Theory

Drawing on leader?member exchange and crossover theory, this study examines how leaders’ work engagement can spread to followers, highlighting the role of leader?member exchange as an underlying explanatory process. Specifically, we investigate if leaders who are highly engaged in their work have better relationships with their followers, which in turn can explain elevated employee engagement. For this purpose, we surveyed 511 employees nested in 88 teams and their team leaders in a large service organization. Employees and supervisors provided data in this multi‐source design. Furthermore, we asked the employees to report their annual performance assessment. We tested our model using multilevel path analyses in Mplus. As hypothesized, leaders’ work engagement enhanced leader?member exchange quality, which in turn boosted employee engagement (mediation model). Moreover, employee engagement was positively linked to performance and negatively linked to turnover intentions. As such, our multilevel field study connects the dots between work engagement research and the leadership literature. We identify leaders’ work engagement as a key to positive leader?follower relationships and a means for promoting employee engagement and performance. Promoting work engagement at the managerial level may be a fruitful starting point for fostering an organizational culture of engagement.     

Optimality conditions for a bilevel matroid problem

In bilevel programming there are two decision makers, the leader and the follower, who act in a hierarchy. In this paper we deal with a weighted matroid problem where each of the decision makers has a different set of weights. The independent set of the matroid that is chosen by the follower determines the payoff to both the leader and the follower according to their different weights. The leader can increase his payoff by changing the weights of the follower, thus influencing the follower’s decision, but he has to pay a penalty for this. We want to find an optimum strategy for the leader. This is a bilevel programming problem with continuous variables in the upper level and a parametric weighted matroid problem in the lower level. We analyze the structure of the lower level problem. We use this structure to develop local optimality criteria for the bilevel problem that can be verified in polynomial time.     

Social Trust and E-Commerce: Experimental Evidence for the Effects of Social Trust on Individuals' Economic Behavior

In this study, an experimental design embedded in a nationalsurvey is used to examine the impact of social trust on participationin e-commerce. To what extent does generalized trust in peopleinfluence economic behavior, particularly in newly establishedrealms such as the Internet? Although some previous work hasposited a role for social trust in encouraging both e-commerceand economic development more generally, evidence has been basedon cross-sectional associations and, primarily, at the aggregatelevel of entire countries. While these relationships have beensuggestive, studies have yet to confirm a causal role for socialtrust in influencing e-commerce. Would increasing levels ofsocial trust actually encourage greater e-commerce participation?This study combines the representativeness of a national surveywith the internal validity of an experimental design to answerthis question.
