The present study examined the longitudinal links between perceptions of family connectedness and body satisfaction in 1,774 (52% female) adolescents. Participants (10–15 years of age at Time 1) completed self-report measures at three measurement occasions separated by 1 year each. Mean group difference results showed that both body satisfaction levels and perceived levels of family connectedness decreased over 2 years for the whole sample. As expected, girls were generally less satisfied with their bodies than boys, particularly in the older cohort. Structural equation modelling was used to assess stability coefficients and cross-lagged effects, and longitudinal bidirectional effects between perceptions of family connectedness and body satisfaction were found for girls, but not for boys. This result suggests that adolescent girls’ body satisfaction is both affected by and a predictor of perceived family connectedness.  相似文献

Considerable research has focused on the reliability and validity of informant reports of family behavior, especially maternal reports of adolescent problem behavior. None of these studies, however, has based their orientation on a theoretical model of interpersonal perception. In this study we used the social relations model (SRM) to examine family members’ reports of each others’ externalizing and internalizing problem behavior. Two parents and two adolescents in 69 families rated each others’ behavior within a round-robin design. SRM analysis showed that within-family perceptions of externalizing and internalizing behaviors are consistently due to three sources of variance; perceiver, target, and family effects. A family/contextual effect on informant reports of problem behavior has not been previously reported.  相似文献

This article aims to assess the role of important socio-economic factors in the family history of tuberculosis patients in Pakistan. Data were collected from 269 patients, and a logistic regression was used to determine the association between risk factors and the vicious circle of TB. Results of the logistic model show that significant risk factors associated with TB history in patients were education, household size, house structure, rooms in the home, room ventilation, monthly income, income food sufficiency, smoking, diabetes, and heart disease. The current TB control programme needs to formulate strategies to target specific risk factors and poverty reduction simultaneously to break the vicious circle of tuberculosis.  相似文献

Public and academic debates often lament a “crisis of trust” endangering democratic stability. In contrast, this article seeks to demonstrate the value of distrust in political relations, a certain form of which should be considered, such as trust, a prerequisite of democracies. To underline this thesis, this contribution discusses categories that clarify the relationality of the concept of distrust (its directedness and modalities) and that allow for a discussion of the relation of trust and distrust, which are introduced as an asymmetrical pair of opposites – with far-reaching consequences for the common discourse on trust. After presenting several historical and current arguments in favor of the value of political distrust, this article will end with a deeper look on those forms of distrust that should indeed be considered dysfunctional and dangerous for democratic orders.  相似文献

The past decade has witnessed an intensifying focus on the development of irrigation in sub-Saharan Africa. It follows a 20-year hiatus in the wake of disappointing irrigation performance during the 1970s and 1980s. Persistent low productivity in African agriculture and vulnerability of African food supplies to increasing instability in international commodity markets are driving pan-African agricultural investment initiatives, such as the Comprehensive Africa Agricultural Development Programme (CAADP), that identify as a priority the improvement in reliability of water control for agriculture. The paper argues that, for such initiatives to be effective, there needs to be a re-appraisal of current dynamics of irrigation development in sub-Saharan Africa, particularly with respect to the role of small-scale producers’ initiatives in expanding irrigation. The paper reviews the principal forms such initiatives take and argues that official narratives and statistics on African irrigation often underestimate the extent of such activities. The paper identifies five key characteristics which, it argues, contradict widely held assumptions that inform irrigation policy in Africa. The paper concludes by offering a definition of ‘farmer-led irrigation’ that embraces a range of interaction between producers and commercial, government and non-government agencies, and identifies priority areas for research on the growth potential and impact of such interactions and strategies for their future development.  相似文献

This study investigates to what extent the use of different performance management techniques within (semi-) autonomous public sector organizations, also called public agencies, can be explained by the defining organizational features of such organizations. Using multi-country survey data of over 400 public agencies, the effect of these features—internal performance target setting and monitoring, multi-year planning, as well as the internal performance-based allocation of resources—upon three performance management techniques has been studied. This set-up recognizes differences among management techniques, as well as recurring factors, allowing us to make more general statements. Analyses illustrate that external result control by the minister and parent ministry positively affects the use of all performance management techniques examined in public agencies. However, each performance management technique is affected differently by specific organizational variables.  相似文献

Abstract

This paper analyses Transatlantic Trade and Investment Partnership (TTIP) negotiations in order to assess how the move towards tighter economic integration within the EU?US strategic partnership impacts on legislative?executive relations in EU trade policy. The analysis examines the institutional, substantive and party political dimensions of national parliaments’ scrutiny of the Common Commercial Policy. Based on insights into both domestic and EU channels of parliamentary monitoring of TTIP negotiations, the paper argues that, although the government remains the central object of democratic control, the involvement of national parliaments in transatlantic trade extends to encompass the EU’s own transatlantic and trade policies. This is rooted in the legislatures’ legal capacity to constrain the executive in the negotiation, conclusion and, where applicable, ratification phases of EU trade agreements. It is argued that national parliamentary influence takes the shape of politicisation of the legitimacy of the expected policy outcomes of these agreements.  相似文献

As we know from comparative public policy, bureaucracies contribute to a considerable degree to the contents and the ways of policy-making. One important driver of administrative policy-making are their specific “styles” or “cultures”. “Administrative styles” are understood here as the standard operating procedures and routines that characterize the behavior and activities of administrative bodies in initiating, drafting and implementing policy. In this article, we convey the concept of Administrative Styles to the level of International Organizations (IOs) and apply it to the Organization for Economic Development and Co-Operation (OECD). The article proceeds in three steps: First, the concept of administrative styles is introduced and refined. Drawing on expert interviews with OECD staff, we secondly show that consideration of OECD administrative styles significantly advances the literature’s understanding of the organization. Finally, we give an outlook on new research avenues and the relevance of our findings for the study of International Public Administrations (IPAs) more generally.  相似文献
