Previous research has shown that young children robustly display in‐group favoritism; that is, they favor in‐group over out‐group members. Moreover, preschoolers also consider information on morality in their evaluations of others. In the present study, we integrated both aspects: In particular, fifty‐six 4‐ to 6‐year‐old preschoolers were assigned to minimal groups and observed either prosocial or antisocial acts conducted by either an in‐group or an out‐group member. After observing these behaviors, children's liking and sharing were significantly higher for moral compared to immoral actors. In addition, children's liking and sharing were substantially higher for in‐group compared to out‐group actors. However, when children were directly asked to morally evaluate the actor's conduct, no in‐group favoritism emerged: In particular, children evaluated immoral acts conducted by an in‐group or an out‐group agent as equally bad/wrong and similarly claimed that these acts deserve punishment. These findings demonstrate that preschoolers differentially weigh information on group membership and moral valence depending on the type of evaluation, namely sharing and liking versus explicit moral evaluations of others’ conduct.  相似文献

Virtual and Extended enterprises share a large amount of characteristics. Especially when it comes to the process of their foundation either one is well advised to base itself on a strong network of reliable partners. In this network each of the joining companies that form the Virtual enterprise can concentrate on their core competencies, giving the whole enterprise the chance to be extremely efficient. Bringing together the different partners and managing them is seen as being one of the biggest challenges of the Virtual enterprise. Therefore some partners will have to focus on those managing tasks. It might as well be their responsibility to ensure that no legal conflicts in regard to the foundation, dissolving, production and related topics emerge. This being especially difficult because the efficiency of a Virtual enterprise is strongly dependent on the looseness of its structure. What conflicts can appear in the described environment and how they might be solved is the focus of this article. It will be pointed out that the emergence of Virtual and Extended enterprises should be supported by general terms and conditions. This terms and conditions should be adjustable, offer the chance to establish a legal framework fitting just perfectly to the intended purpose to continuously create, adjust or dissolve Virtual enterprise. As a matter of fact a certain degree of commitment can positively expand the co-operation in a Virtual enterprise which is mainly based on trust.  相似文献

Even though war gaming and scenario planning are widely used in business contexts, there is little evidence that either practice is associated with superior performance. Why, then, spend the costs? In this paper we address this puzzle and suggest why the extant empirical findings have so far proven limited. We consider the development of these practices and find that they have a substantially entangled and overlapping history, particularly at the RAND Corporation in the 1950s. Despite shared historical roots, the treatment of war gaming and scenario planning in the scholarly literature branched out into different streams. This separation is unfortunate because it obscures a better understanding of the premises under which these practices are effective. We propose an analysis of the overlaps and contrasts of war gaming and scenario planning that sets out clear boundary conditions for their use and efficacy. We find that each practice is tailored to provide strategic guidance in a context where the organization is facing different forms of uncertainty. This suggests they may be effective, and thus improve organizational performance, where the relevant uncertainties are operative. Such benefits would be apparent over longer time scales, and only if the relevant boundary conditions are met. However, to the best of our knowledge, no longitudinal empirical test of either war gaming or scenario planning is available. We therefore conclude that more research is needed to ascertain the true relationship between these popular practices and their performance outcomes.  相似文献

Across the globe, the countryside faces the “generation problem”: Who will grow food when the current generation of aging small farmers and peasants disappears? A combination of objective and subjective factors effectively discourages young people from assuming the continuity of peasant and family farming, especially in countries that have experienced significant neoliberal dismantling of rural infrastructure and education. Rural social movements are increasingly building educational processes linked with small-scale, ecological farming in the hopes of reinforcing the development of identities and skills for peasant futures and cadre in the struggle for popular land reform, agroecology, and food sovereignty.  相似文献

The main elements of the ongoing reform of youth welfare in Germany “Neue Steuerung” (“New Regulation”) are the reconstruction of its administration, local networking and the transfer of economical criterions to the context of social work. Advisors and coaches, working in this field, are confronted with a problem, which is highly characterized by institutional dynamics of changes, and especially with the question of efficiency of social measures. We think, it is important that advisers, coaches an supervisors, who work in this field of “New Regulation”, are informed profoundly of the current state of the reform of the administration in their region, that they find their own point-of-view to the theme of pressure in financing social measures and social providing, and that they create a flexible supply of consultation, which is comprehensive in methods and that they cooperate with their clients` institutions.  相似文献

This study describes the forced sexual experiences, serious internalizing problems, risky sexual behavior, and alcohol-related correlates of risky sexual behavior of 120 substance abusing adolescents and young adults (87 men, 33 women; mean age = 17.2 years) undergoing treatment. Prior coerced sexual experiences were associated with suicidal thoughts and attempts, higher levels of risky sexual behaviors, avoidance motives for drinking, and sexual decision-making conducive to risky sexual behavior. Sexual coercion was associated with patterns of sexual behavior and alcohol use that potentially increase vulnerability to HIV exposure. Social workers can play a number of significant roles in addressing ongoing psychological distress associated with sexual coercion among these predominantly female adolescents. Therefore, effective social work practice should enhance treatment effectiveness and reduce risk for a range of maladaptive outcomes including exposure to sexually transmitted diseases (STDs) and revictimization.  相似文献

We consider a sequence of posterior distributions based on a data-dependent prior (which we shall refer to as a pseudoposterior distribution) and establish simple conditions under which the sequence is Hellinger consistent. It is shown how investigations into these pseudo posteriors assist with the understanding of some true posterior distributions, including Pólya trees, the infinite dimensional exponential family and mixture models.  相似文献

Over the last few decades, night work has been found to be associated with negative somatic consequences; however, there is less knowledge about its impact on mental health. In a sample of 633 Norwegian nurses, we investigated by means of latent growth curve modelling whether different work schedules predicted differences in baseline values of anxiety and depressive symptoms, and trajectories of these over a two-year span. All participants completed the Hospital Anxiety and Depression Scale as part of a larger survey conducted during the winters of 2009, 2010 and 2011. The results revealed that night workers and nurses who changed from day work to night work during the study period did not differ from day workers either in terms of baseline symptoms of anxiety or depression, or in terms of trajectories of these symptoms. However, nurses who changed from night work to day work reported a significant decrease in symptoms of both anxiety and depression over time compared to day workers. Furthermore, supporting previous work, languidity was related to higher anxiety and depression and hardiness to lower levels of those symptoms. Possible mechanisms underlying the results are discussed.  相似文献

How does a firm’s IT architecture affect its potential to outsource business processes? As Information Technology (IT) has become many firms’ essential operational infrastructure or “backbone”, we are interested in scrutinizing to what extent the kind of IT architecture affects a firm’s boundaries or the plasticity of its boundaries. Focusing on the particular concept of service-oriented architectures (SOA), we concretely ask: How does SOA affect business process outsourcing potentials? Since SOA is widely expected to modularize the IT implementation of business processes, it should increase business process outsourcing (BPO) in terms of buying in the provision of single business functionalities. We develop and empirically evaluate a theoretical model that conceptualizes the relationship between SOA and BPO. Questionnaire data from 115 firms give first evidence that SOA facilitates BPO. By increasing IT modularity, SOA supports BPO by increasing sourcing flexibility and, in particular, operational benefits, while at the same time lowering financial risks and strategic risks, such as lock-in. Overall, however, firms see SOA-based BPO mainly in an operational context with low hidden costs and little strategic benefits.  相似文献
