Homeless youth lack the traditional support networks of their housed peers, which increases their risk for poor health outcomes. Using a multilevel dyadic analytic approach, this study identified characteristics of social contacts, relationships, and social networks associated with the provision of tangible and emotional support to homeless youth (N = 419, M age = 20.09, SD = 2.80). Support providers were likely to be family members, sex partners, or non–street‐based contacts. The provision of support was also associated with contacts' employment and homelessness status, frequency of contact, shared risk behaviors, and the number of network members that were homeless and employed. The results provide insights into how homeless youth could be assisted to develop more supportive social networks. 相似文献

What prevents women, who wish to pursue a career, from gaining power???If organizational micro-politics, which means using and developing power, is conceptualized as an acting competence, the acquisition of cognitive competences and also the willingness to act micro-politically will turn into focus, which can be regarded as an indicator for the integration of micro-political acting into a self-concept. According to common models of competences this illustrates self-competence. The interviews conducted with female young executives revealed that the willingness??more than the ??pure motivation to advance a career????represents a key factor to be successful in advancing a career. The willingness seems to be even more marked, the less the self-concept is linked to female gender-stereotype. With regards to this result it is discussed what this means to the development of micro-political competences for women. 相似文献

Since the Last Planner System® (LPS) was devised in the early 90s, a number of studies have pointed out the need to understand the underlying theory in which it is based on. The Language-Action Perspective (LAP) has been suggested as a suitable approach to understand the management of commitments in the LPS. This paper aims to assess the contribution of LAP to understand construction planning and control systems based on LPS. Two case studies were carried out in different construction companies, both highly experienced on the use of LPS. The results reveal the role of LAP for creating explicit representations of commitment flows that can be used to explain the sources of complexity and failures in planning systems, as well as for describing the profile of planning and control meetings. 相似文献

We implement a risky choice experiment based on one-dimensional choice variables and risk neutrality induced via binary lottery incentives. Each participant confronts many parameter constellations with varying optimal payoffs. We assess (sub)optimality, as well as (non)optimal satisficing by eliciting aspirations in addition to choices. Treatments differ in the probability that a binary random event, which are payoff—but not optimal choice—relevant is experimentally induced and whether participants choose portfolios directly or via satisficing, i.e., by forming aspirations and checking for satisficing before making their choice. By incentivizing aspiration formation, we can test satisficing, and in cases of satisficing, determine whether it is optimal. 相似文献

Summary. We propose covariance-regularized regression, a family of methods for prediction in high dimensional settings that uses a shrunken estimate of the inverse covariance matrix of the features to achieve superior prediction. An estimate of the inverse covariance matrix is obtained by maximizing the log-likelihood of the data, under a multivariate normal model, subject to a penalty; it is then used to estimate coefficients for the regression of the response onto the features. We show that ridge regression, the lasso and the elastic net are special cases of covariance-regularized regression, and we demonstrate that certain previously unexplored forms of covariance-regularized regression can outperform existing methods in a range of situations. The covariance-regularized regression framework is extended to generalized linear models and linear discriminant analysis, and is used to analyse gene expression data sets with multiple class and survival outcomes. 相似文献

Portugal and Spain underwent dramatic transformations between 1974 and the early 1980s, transitioning from dictatorships to democracies. In this article I explore why Portugal was faster than Spain in adopting key gender-rights policies (e.g., divorce, equal pay, state feminism) during the period in question. Bridging insights from the democratization, social movement, and women’s studies literatures, I argue that Portugal’s accelerated policy path on women’s rights can be explained by three complex factors: (1) the nature of the revolutionary transition, which structured options for women’s movements and for institutional actors; (2) the configuration of movement-party alliances; and (3) supranational pressures to reorganize the state-civil society relationship. The study contributes to the engendering of democratization processes in Iberia by paying close attention to the interconnected agency of women’s movements with other political actors at a time of regime transformation. 相似文献

Even though the millennium development goals (MDGs) tackle the main economic and social problems in developing countries,
nutrition is not addressed adequately despite its important role in achieving the MDGs. It is therefore crucial to mainstream
nutrition by strengthening public-private partnerships, increased political and technical capacity and by achieving food security.
The paper aims to discuss how strong partnerships bringing public and private efforts together are important to the success
of increasing nutritional programs by providing a redesign and marketing of products and services, other services, and funding.
The report explores the need to assess the setting of pertinent nutritional policies and to increase technical capacity. The
study found that the relation between agriculture and nutrition is a key component for achieving food safety in order to mainstream
nutrition into the MDGs. The three main topics considered in this analysis are biotechnology, food trade policies, and bioenergy
products as they have a strong impact on prices. Mainstreaming Nutrition for better development outcomes.

Learning to walk is a dynamic process requiring the fine coordination, assembly, and balancing of many body segments at once. For the young walker, coordinating all these behavioral levels may be quite daunting. In this study, we examine the whole‐body strategies to which infants resort to produce their first independent steps and progress over the first months of walking experience. Six infants were followed weekly from the onset of independent upright locomotion for 8 weeks, and then every other week until 4 months of walking experience. The walking kinematics from the infants' earliest steps were cluster‐analyzed and the infants were classified into 3 groups. Follow‐up comparisons with kinematics recordings were used to quantify the infants' strategies more precisely and track how these early forms of walking evolved over time. Results revealed that in the first weeks of independent walking, 3 infants used a stepping strategy, 1 used a twisting strategy, and 2 used a falling strategy to move their body forward and perform their first unsupported steps. As the infants gained walking experience, their walking patterns became more similar. These findings indicate that infants discover different solutions to use their body and control their balance when beginning to walk. With time, infants adopt a more efficient solution that incorporates and integrates elements of the different strategies. 相似文献

In this article, we focus on the analysis of individual decision‐making for the formation of social networks, using experimentally generated data. We analyze the determinants of the individual demand for links under the assumption of agents' static expectations and identify patterns of behavior that correspond to three specific objectives: players propose links so as to maximize expected profits (myopic best response strategy); players attempt to establish the largest number of direct links (reciprocator strategy); and players maximize expected profits per direct link (opportunistic strategy). These strategies explain approximately 74% of the observed choices. We demonstrate that they are deliberately adopted and, by means of a finite mixture model, well identified and separated in our sample. (JEL C33, C35, C90, D85) 相似文献
