Scholars have suggested that skill (Ferris et al., 2007) and motivation (Forret and Dougherty, 2001) need to be considered in predicting the direction and intensity of networking behaviors. Congruently, the present study argues that skill and motivation operate interactively and assesses the interactive impact of political skill (i.e., the ability to interact effectively with others) and future time perspective on differentially predicting community-based and career-based networking behavior. Results from a sample of managers from a national retail chain (n = 291) indicated that politically skilled individuals who possessed a deep future time perspective were more involved in career-related networking than politically skilled individuals who perceived a shallow future time perspective. Additionally, politically skilled respondents with shallow organizational time perspectives engaged in higher levels of community-based networking than did their counterparts with deeper organizational time perspectives. The implications of these findings are discussed in terms of political skill, social networks, and socioemotional selectivity theory.  相似文献

This article explores how the scope of solutions to complex problems is determined by the way in which the problem is formulated. We inquire into this by means of a theory-driven case study of the reform in the Norwegian drug rehabilitation sector and the Tyrili facility. We analyze divergent approaches to drug rehabilitation by means of a problem formulation framework, which distinguishes between (1) the value dimensions of given problems, and (2) the phases of problem solving activities. Based on this inquiry, we arrive at a set of propositions, in which we propose that the two approaches differ in their inclusion of various value dimensions. Moreover, we suggest that the reform pursued increased efficiency as a solution to a reductionist formulation of the problem, which challenged Tyrili's opportunity to solve the problem in the multidimensional manner they conceive of it. This is an argument against a one-dimensional maximization of efficiency as a pursuit of quality in social services.  相似文献

Researchers have established that individual religiosity influences sexual behavior and that religious support can increase consistency between personal religiosity and behavior. Researchers are less certain, however, of the effect that religious friendship networks have on sexual behavior. In addition, the effects of network characteristics such as density and one’s position in a social network have not been established. This paper uses a network subsample of the National Longitudinal Study of Adolescent Health (Add Health) to examine the effect of friends’ religiosity on the probability of first sex. We find that friends’ religiosity has an independent influence on adolescent sexual behavior that is similar in magnitude to personal religiosity. We also find evidence that friends’ religiosity has the strongest influence on the sexual behavior of adolescents who are embedded in dense social networks, in which teens’ friends are also friends with one another. These results support the hypothesis that group influences depend on the degree of embeddedness within the network and highlight the importance of studying religion as a property of groups as well as individuals.  相似文献

Records of gas flow during breathing are cyclical, with the cycles varying in duration. The shape of these cycles may change with the intensity of respiratory stimulation or the development of respiratory disease, but currently research is hampered by the lack of a fully satisfactory technique for determining the shape of a typical cycle. The approach adopted here is to replace the time series by a 'phase diagram', plotting the time integral of flow against flow itself. Principal curves are then fitted. These are curves `through the middle of the data' which were introduced by Hastie and Stuetzle. The shapes of these curves are compared, either directly or after reconstructing an average cycle corresponding to each fitted curve. This has the advantage that the shape of the waveform is separated from the amplitude, and from the duration of the breath. A disadvantage is that periods of zero flow are lost, and the reconstructed average cycle may show irregularities at points near zero flow as a result. In practice, the methodology showed clear differences in shape between the protocols, gave reasonable average cycles and ordered the waveform shapes according to the hardness of breathing induced by the protocols.  相似文献

We use data from the Early Childhood Longitudinal Study, Kindergarten Class of 1998–1999 as well as neighborhood data from the 2000 U.S. Census to examine relationships between neighborhood Mexican immigrant concentration and reading (n = 820) and mathematics (n = 1,540) achievement among children of Mexican descent. Mixed-effects growth curves show that children living in immigrant-rich communities enter school at an achievement disadvantage relative to children in neighborhoods with fewer coethnic immigrant families. However, these disparities are driven by lower-SES families’ concentration in immigrant-heavy neighborhoods as well as these neighborhoods’ structural disadvantages. Controlling for children’s generation status and socioeconomic status, as well as neighborhood-level measures of structural disadvantage, safety, and social support, neighborhood immigrant concentration demonstrates a modest positive association with mathematics achievement among children of Mexican immigrant parents at the time of school entry. However, we do not find strong positive associations between Mexican American children’s rate of achievement growth over the elementary and middle school years and their neighborhoods’ concentration of Mexican immigrants.  相似文献

ABSTRACT

Childhood trauma can have a lasting effect on personality and daily functioning, leading to dissociative changes in behavior and identity. How these are interpreted and handled usually depends on local culture and beliefs. This article presents the case of a Mauritian woman with a history of childhood abuse who was exorcised to “dispel an evil spirit.” An in-depth interview exploring her experiences and meaning-making was transcribed and subjected to interpretative phenomenological analysis. This article discusses possession as a culturally accepted metaphor for incomprehensible behaviors. It shows that help-seeking pathways are determined by symptom interpretation models that are reinforced by the local environment. It also demonstrates that exorcisms are potentially retraumatizing by the enactment of painful memories and emotions during this ritual. The authors stipulate that exorcism seekers could benefit from additional clinical assessment by professionals experienced in the dissociation field.  相似文献

With exponential growth in the Latino population over the past decade, both social scientists and politicians have directed their attention toward understanding Latino behavior(s) ranging from purchasing power and marketing to voting. Less is known, however, about the extent to which Latino population growth might be associated with patterns of criminal justice or violent criminal outcomes. One objective of this research is to provide a contemporary overview of the Latino experiences with the criminal justice system by highlighting racial/ethnic disparities in incarceration and sentencing. Using racial-/ethnic-specific homicide victimization data provided by the Centers for Disease Control, we also examine the impact of Latino concentration on levels of group-specific homicide, both regionally and nationally. Results from our negative binomial multivariate analyses indicate that the concentration of Latinos tends to be associated with lower levels of homicide victimization, a finding that holds across racial/ethnic groups and geographic specification. We conclude with a discussion of the implications of these findings with an eye toward future research in this area.  相似文献
