Alcohol use is pervasive in adolescence. Though most research is concerned with how friends influence drinking, alcohol is also important for connecting teens to one another. Prior studies have not distinguished between new friendship creation, and existing friendship durability, however. We argue that accounting for distinctions in creation–durability processes is critical for understanding the selection mechanisms drawing drinkers into homophilous friendships, and the social integration that results. In order to address these issues, we applied stochastic actor based models of network dynamics to National Longitudinal Study of Adolescent Health data. Adolescents only modestly prefer new friendships with others who drinker similarly, but greatly prefer friends who indirectly connect them to homophilous drinkers. These indirect homophilous drinker relationships are shorter lived, however, and suggest that drinking is a social focus that connects adolescents via proximity, rather than assortativity. These findings suggest that drinking leads to more situational and superficial social integration.  相似文献

The paper describes the group therapy model which has evolved over the past two years on the Child Psychiatry Inpatient Unit of North Carolina Memorial Hospital. It begins with a brief review of the literature concerning group therapy with latency-aged children. The setting and patient population are described. Vignettes from group sessions are used to illustrate techniques which have evolved to deal with this particular setting and population. These include a leadership style characterized by much clarification, modeling, and limit setting; extensive focus on beginning and terminating; clearly defined behavioral limits; the use of time out; and use of play materials requiring little skill or attention as anxiety binders as well as projective media; and observation and supervisory discussions open to all members of the treatment team. The paper concludes with a discussion of the potentials and limitations of group therapy in such a setting. The thesis is that this model is effective in diagnosing developmental levels, in developing interpersonal skills, in substituting verbalization for action, and in mastering separation anxieties, though the setting limits the extent to which controlled regression, transference, and group pressures can develop and be used to produce change.  相似文献

This paper examines the determinants of base pay and total incentive compensation packages of CEOs of biopharmaceutical firms that have recently gone public, and whether human capital and agency factors affect the market’s response to the initial public offering. We find that in terms of net proceeds, the IPO market appears to reward the firms that have founder-CEOs and CEOs with higher incentive compensation. CEOs with prior venture capital experience are associated with receiving higher incentive compensation, while CEOs with a greater ownership interest in the firm receive lower incentive compensation but higher salaries. CEOs of firms with a greater percentage of insiders are associated with lower salaries. The results should add to our understanding related to human capital and agency theories, as well as help firms and investors better understand and structure CEO compensation.  相似文献

Upper bounds axe derived for the efficiency factor of a class of resolvable incomplete block designs known as latinized designs. These designs are particularly useful in glasshouse and field trials, and can be readily extended to two-dimensional blocking structures. Existing bounds for resolvable designs axe also reviewed and a comparison is made between the third moment bounds discussed by Jarrett (1989) and the second moment bounds of Tjur (1990).  相似文献

The objectives of this research were to explore patterns of heterosexual activity in early adolescence and to examine the differential pathways to light and heavy heterosexuality. We utilized the National Longitudinal Survey of Canadian Children and Youth (NLSCY) in which heterosexual behaviors, as well as puberty, parenting processes, peer self‐concept, and problem behaviors were examined. The heterosexual activities of the majority of 12‐ and 13‐year‐old adolescents were largely confined to light activities of hugging, holding hands, and kissing. Heavy activities such as petting and sexual intercourse were reported less often. Using predictor variables from Cycle 1 of the NLSCY when participants were 10‐ and 11‐year‐olds, SEM analyses indicated that puberty and higher peer self‐concept shared significant direct pathways to both light and heavy heterosexuality. Heavy sexual activity, however, was uniquely associated with the risk factors of adolescent problem behaviors. Positive and hostile parenting styles were indirectly associated with light sexual activity through peer self‐concept. Positive and hostile parenting styles were also indirectly associated with heavy sexual activity through both peer‐oriented self‐concept and problem behaviors. Results support differential patterns and predictors of light and heavy sexuality in early adolescence.  相似文献

Youth-Subcultural Studies: Sociological Traditions and Core Concepts   总被引:1,自引:1,他引:0  
The study of youth subcultures has rich histories in the USA and UK, yet has remained a marginal subfield within cultural sociology. In this article, I begin by reviewing the significance of the Chicago school, strain theory, Birmingham school and post-subcultural studies traditions of youth-cultural and youth-subcultural research. I then conceive of a series of significant analytic concepts that over time have proven themselves to be core components of youth-subcultural studies. These analytic concepts include subcultural style, resistance, subcultural space and media, societal reaction, and identity and authenticity. In each analytic section, I explore major conceptual frames and discuss significant empirical research, on youth subcultures including punk goth, straightedge, riot grrrl skateboarding, rave and club cultures, among others.  相似文献

Abstract This study examines parents' decisions about educating some or all of their children beyond primary school in rural Thailand. Their strategies often involve choices between sons and daughters and between older versus younger children. We find that the more children there are in a family, the lower the proportion who are sent to secondary school. Parents send more sons than daughters and more youngest than eldest children. The decision is sometimes associated with a specific “investment” strategy, but it may also reflect parents' ability to afford to send children beyond primary school. Important economic factors include children's perceived earning potentials, anticipated opportunity costs, and parents' poverty status. However, the issues of access to schools and the safety of children, particularly girls, are also critically important. These concerns are often weighed as heavily, or more heavily, than economic considerations.  相似文献

This paper addresses crisis communication shortcomings of oil companies working in the Nigerian delta region. The anticipatory model of crisis communication is blended with the public relations relational perspective to demonstrate how oil companies have responded to crises in the delta region in a manner contrary to what would be consistent with these perspectives. The result has been persistent turmoil in the region and significant distrust of the organizations.  相似文献

In response to a growing diversity of opinion regarding educational models and essential content in clinical social work education, this paper offers a perspective concerning graduate clinical curricula. Part I, the foundational piece of the paper, discusses the definition of clinical social work, social work’s core orientation and values, and influential contextual issues. The interrelated core orientations guiding knowledge and skill development are identified as the person-in-situation perspective and the concept of relationship. Based on this foundation, Part II identifies elements of a contemporary biopsychosocial knowledge base and essential clinical skills. This paper is intended to stimulate dialogue about a topic of importance to the profession and the clients it serves.  相似文献

SenGupta (1987) proposed a locally most powerful test which is globally (one sided) unbiased, and an estimator of p, the equicorrelation coefficient of a standard symmetric multivariate normal (SSMN) distribution. Here we use the idea in Williams (1984) to illustrate the construction and use of ancillary statistics to make inference about p. The test and confidence intervals based on this construction are conditionally optimal.  相似文献
