This research examined whether 10‐month‐old infants expect agents to perform equal distribution of resources. In Experiment 1, infants saw a distributor performing either an equal distribution where one strawberry was given to each of two recipients, or an unequal distribution that favored one of the recipients. Infants looked longer at the unequal test event, suggesting that they expected the strawberries to be distributed equally. In Experiment 2, the potential recipients were replaced with inanimate objects to rule out a lower‐level alternative explanation of the results in Experiment 1 based on symmetric movement of the distributor. Infants' looking times did not reveal a preference for one of the two outcomes of the test events (i.e., symmetric or asymmetric movement). Experiment 3 controlled for the role of the distributive action, that is, here the distributors only removed barriers revealing strawberries that the recipients already had. No preference was observed when an equal or unequal initial allocation of resources was revealed. Experiment 4 assessed whether infants relied on affiliative information provided by the distributor's movements. The distributor made the same movements as in Experiment 1, but without distributing any strawberries, and no difference in looking times was observed. These findings support the view that preverbal infants expect agents to behave according to a simple principle: Resources are to be distributed equally among equivalent recipients. We discuss the possible links between such reactions and the emergence of an early sense of fairness.  相似文献

We search for agent behavior rules which lead to the emergence of social networks that exhibit empirically observed phenomena: small-world property, scale-free degree distribution and stability in time. We assume that agents form and sever links using a cost-benefit analysis. Agents receive benefit from own links and from links that their friends form. On the other hand, link formation, deletion and keeping is costly. We find that a simple model structure which relies only on convex cost of link upkeep leads to stable networks which exhibit the small-world property.  相似文献

The main objective of the paper is to identify and explore specifics and trends of international scientific collaboration in the field of strategic management in Europe over the last quarter‐century. Specifically, the study analyses those scholarly connections between countries and cities on the basis of co‐authorship to determine the flow of knowledge from the geographical aspect, as well as the state of collaboration among different authors (co‐authorship and citations' networks), that is, the depth of such network (collaboration intensity) and whether such a scientific community is consistent, i.e. number of connected elements or related networks. This is the first time international scientific collaboration between researchers in the field of strategic management has been studied to such an extent. We employed all sources of relevant data and analyzed 5,237 results from the Scopus and Web of Science databases. Through the application of bibliometric analysis, our study offers a comprehensive and up‐to‐date identification and assessment of trends in international scientific collaboration in the strategic management field in Europe.  相似文献

The purpose of this study was to examine empathy-related and personal correlates of children's comforting reactions. Quantity and quality of third to sixth graders' comforting of a crying infant were assessed and their relations with situational and dispositional empathy-related responding, shyness, and vagal tone were examined. Quantity and quality of boys' comforting were related to reports of sympathetic/empathic responding to an empathy-inducing film, whereas quantity of girls' comforting was associated with low facial and heart rate markers of vicarious distress in another context. Quality of comforting was associated with markers of girls' vicarious distress. Comforting was negatively related to younger children's shyness and marginally, positive correlated with girls' vagal tone. Suppression of vagal tone was associated with quantity of comforting.  相似文献

The paper examines the characteristics of area-based partnerships in rural Poland. It is based on the study of partnerships created after the accession to the European Union in 2004. Partnership structures have been rapidly adopted in rural Poland due to opportunities provided by the LEADER+ Pilot Programme. However, the research showed that partnerships are frequently subject to elite domination by local authorities and hence fail to fully engage a range of community and private sector actors. Funding rules for LEADER, most notably the condition that money will only be paid on the completion of projects, has been particularly significant in perpetuating the domination of partnerships by organisations with existing access to financial and human capital. Hence funding arrangements can undermine the ability of Polish partnerships to operate in ways which harness the endogenous capacities of local communities. To date power differentials between notional ‘partners’ have been experienced to a greater extent than in advanced liberal democracies. The research found that overt domination of partnership structures by state agencies limited the possibilities for community led development initiative in rural Poland.  相似文献

Studies of the rise of private defined-contribution pension plans have traditionally focused on social policy concerns about the allocation of risks and costs for beneficiaries and employers. There is however another dimension of pension privatization, which situates it in the context of financial markets and—more broadly—the economic system. Here, regulations forcing private pension providers to guarantee a minimum rate of return on individuals’ pension assets make a crucial difference for financial markets because they incentivize fund managers to invest a greater chunk of plan portfolios in fixed-income securities and therefore away from equities. While different segments of the financial industry have divergent preferences over minimum return guarantees, politicians are caught in a dilemma: Should they prioritize predictable benefit levels or the development of equity markets? Using the case of the introduction of the German Riester Rente, we argue that, as politicians linked the introduction of private defined-contribution plans with cuts in statutory pensions, insurance firms in coalition with trade unions insisted on minimum guarantees, thereby restricting the expansion of equity markets in Germany.  相似文献

Migration is the principal demographic process shaping patterns of human settlement, and it serves an essential role in human development. While progress has been made in measuring international migration, internal migration statistics are as yet poorly developed in many countries. This article draws on a repository of data established under the IMAGE (Internal Migration Around the GlobE) project to address this deficit by constructing the first comprehensive league table of internal migration intensities for countries around the world. We review previous work, outline the major impediments to making reliable comparisons, and set out a methodology that combines a novel estimation procedure with a flexible spatial aggregation facility. We present the results in the form of league tables of aggregate crude migration intensities that capture all changes of address over one‐year or five‐year intervals for 96 countries, representing four‐fifths of the global population. Explanation for the observed differences has been sought, inter alia, in historical, structural, cultural, and economic forces. We examine the links between development and migration intensity through simple correlations using a range of demographic, economic, and social variables. Results reveal clear associations between internal migration intensities and selected indicators of national development.  相似文献

The Steiner tree problem asks for the shortest tree connecting a given set of terminal points in a metric space. We design new approximation algorithms for the Steiner tree problems using a novel technique of choosing Steiner points in dependence on the possible deviation from the optimal solutions. We achieve the best up to now approximation ratios of 1.644 in arbitrary metric and 1.267 in rectilinear plane, respectively.  相似文献
