This article introduces a cross-cultural research project involving researchers from Bangkok, Thailand, and Vienna, Austria, and explores the effects of social network services (SNS) on practices of friendship initiation and relationship management among young adults. The focus of inquiry was on differences with regard to the organization of social networks, practices of friendship management, and the mutual interference between media and technology usage and lifestyles. On the basis of explorative interviews and group discussions with young adults living in the two cities studied, we developed a standardized online questionnaire to examine how participation in SNS, such as “Facebook” and “Hi5,” has an impact on the meaning of friendship. In addition, we analyzed ego-network structures and their implications for social integration. 相似文献

Abstract: This study develops new histomorphological algorithms for Maya populations’ human ribs and tests the applicability of published algorithms. Thin sections from the fourth rib of 36 individuals of known age were analyzed under polarized light microscopy. Osteon population density (OPD, the concentration of intact and fragmented osteons per mm2), cortical area (CA), and osteon size (OS) were recorded. Seven algorithms were calculated, using all combinations of variables, and compared to the performance of published formulas. The OPD‐based formulas deviate from the known age 8.7 years on average, while those from OS and CA deviate between 10.7 and 12.8 years. In comparison, our OPD‐based algorithms perform better than the one by Stout and Paine and much better than Cho et al. In conclusion, algorithms should be developed using OPD for different ethnic groups; although Stout and Paine’s can be used for Maya and maybe Mesoamerican individuals. 相似文献

Legislators in presidential countries use a variety of mechanisms to advance their electoral careers and connect with relevant constituents. The most frequently studied activities are bill initiation, co-sponsoring, and legislative speeches. In this paper, the authors examine legislators’ information requests (i.e. parliamentary questions) to the government, which have been studied in some parliamentary countries but remain largely unscrutinised in presidential countries. The authors focus on the case of Chile – where strong and cohesive national parties coexist with electoral incentives that emphasise the personal vote – to examine the links between party responsiveness and legislators’ efforts to connect with their electoral constituencies. Making use of a new database of parliamentary questions and a comprehensive sample of geographical references, the authors examine how legislators use this mechanism to forge connections with voters, and find that targeted activities tend to increase as a function of electoral insecurity and progressive ambition. 相似文献

Data from 117 countries over the period 2006 to 2011 are used to estimate a macroeconomic cross-country system of equations that examines the association between terrorism, self-reported life satisfaction, and national income. Results indicate that terrorism is negatively associated with life satisfaction, whereas no such association is found between terrorism and real GDP per worker. Stark contrasts are found, however, between OECD and non-OECD members. In all, our results suggest that the social costs of terrorism are potentially much higher than the economic costs, and measuring only the conventional economic costs of terrorism significantly underestimates the true costs. 相似文献

Child abuse allegations in custody and access disputes are serious matters and present family courts worldwide with major problems. This article reports a large research study just completed that investigated the way the Family Court of Australia managed child abuse cases. The study showed that such cases had become a substantial part of the court's current workload, their "core business" in fact. The families involved had many difficulties, including a history of family violence, and the present system was not appropriate for their particular problems. Thus, as new specialized court lead model of intervention was devised, based on principles relevant to family violence and incorporating the most effective strategies identified in the research. 相似文献

Development research has been through many stages over the past few decades and during this time has experienced fluctuating appreciation by development practice. There is an increasing gap between different ways of doing development research. For some, the purpose of development research is primarily to influence policies, and in order to do this development research has to reframe its whole approach, language, and methodology. Others maintain that development research needs to distance itself, maintain an analytical and even critical approach towards development practice, and become an academic discipline in its own right. 相似文献

Many studies suggest that mixed‐member electoral systems produce different attitudes and behaviors among representatives. This article assesses how this type of electoral system shapes Bolivian legislators' perceptions of their roles as representatives, their district activities, and their relationships with their political parties. It examines these dimensions using elite survey data and interviews with legislators and their personal assistants. The results show that the electoral system does not produce a uniform impact. It shapes how legislators perceive their role as representatives and the nature of the relationship they build with their political parties, but it does not produce differences in the kinds of activities that both types of legislators carry out in their districts. 相似文献
