This article focuses on differences between teenagers who became sexually active in early adolescence (15 or younger) and those who did so in late adolescence (16–19). It reviews research on adolescent sexual behavior and summarizes findings on factors associated with adolescent coitus. The few findings on the meaning of first coitus are also noted. A study which used a sample of already-pregnant adolescents is presented in detail. While few differences between those who first had coitus during early adolescence and those who had it later were significant, most were in the predicted direction, and none were contrary to the hypotheses. A major significant difference concerned the relationship between sex and love; those who found the two related tended to start their sexual careers later than those who did not. Policy implications of research findings are discussed, especially those relevant to sex education.This research was supported in part by Grant No. HD 11099 NICHD, and in part by Grant No. 78-499, Charles Stewart Mott Foundation.This article is a revision of a paper presented at the Annual Meetings of the Society for the Study of Social Problems, August 26, 1980, New York, N.Y.  相似文献

Conceptual model and map of psychological abuse of older adults   总被引:2,自引:2,他引:0  
Psychological abuse of older adults is a hidden and pervasive problem that is not well conceptualized nor well measured. Goals. The goals were to (a) conceptualize psychological abuse using three-dimensional concept maps, and (b) develop theoretical models. Methods. Statements describing the construct were generated by local and national panels. These were sorted and rated using Concept Systems software whereby the concepts were depicted as a map. Results. The concept maps guided development of theoretical hierarchies. Significance. Theoretical models may help to develop measures to estimate prevalence better and may enable more precise screening for triage into appropriate interventions.  相似文献

Abstract

This research focuses on responsiveness in high variety manufacturing environments. To achieve it, the article proposes to develop Dynamic Response Capabilities (DRCs) of the manufacturing system defined as the abilities to readjust the planned operating parameters of workload, capacity, and lead time, in the wake of disturbances. To inform their development, built on the Workload Control theory, a routine-based framework is proposed. The framework supports an integrated approach for the implementation of adaptive decision-making routines for workload, capacity, and lead time readjustments at different stages in the order fulfilment process. Findings from two empirical cases show the appropriateness of the framework to develop and utilise DRCs in different settings of disturbances. Results of a simulation study, with one of the case companies, also shows the effectiveness of the framework to drive performance improvements in presence of recurring disturbances leading to demand variability.  相似文献

Abstract

We review the literature on nonstandard work with three aims: to portray the breadth and nature of the research and theorizing to date, to document the challenges and opportunities this domain poses to both practice and theory, and to bring the study of nonstandard work more to the center stage of micro-OB. After defining nonstandard work and documenting scholarly interest in it, we discuss the literature on the experience of nonstandard workers, on managing the nonstandard workforce, as well as that on managing the interface between standard and nonstandard workers. We analyze the themes that are raised in these literatures and point to new research questions that need to be addressed. Research on nonstandard work can enhance our understanding of the nature of work, the relationship between individuals and organizations, and how organizations and individuals can undertake these new work forms.  相似文献

This study assesses the gendering of emotions’ claims in an understudied population, that is, adolescents in mainland China. Specifically, it examines gender variations in the emotional reactions to relational strains and gendered responses to emotions with types of delinquency. Data drawn from over 500 middle‐school students from an urban city in China yield results in support of general strain theory in most respects, but culture‐specific patterns are noted. In general, Chinese boys and girls respond to different domains of relational strains, and relational strains are more strongly associated with depression than anger. Furthermore, boys respond to relational strains with anger more often than do girls, whereas girls and boys are about equal in responding to strains with depression. Gender differences are observed concerning responses to emotions with delinquency. Boys are more likely than girls to use aggression in response to anger and depression, whereas no gender differences are manifested in the reaction to emotions with non‐aggressive delinquency. Gender patterns are also noted in the assessment of negative emotions as mediators of the strain–delinquency relationship. We address these findings along with other observations in light of general strain theory and sociocultural factors pertinent to mainland China.  相似文献

There is a rapidly growing industry of online learning and distance education programs at the Master of Social Work and Bachelor of Social Work levels both within Australia and globally. A number of best practices have emerged from the literature that warrant consideration when delivering social work programs in online learning and distance education modes. Given the significant advancements in technology that are likely to continue into the next decades, social work academic leaders and accrediting bodies must be prepared to address the changing landscape of higher education, including limited financial resources. Social work academics need to become aware and implement best practices in online learning and distance education e-teaching environments to ensure positive student outcomes, student retention, and student engagement to meet the flexibility needs of students in higher education settings. The purpose of this paper is to identify and discuss the challenges and benefits of distance education and online learning for consideration when providing a social work program in these delivery models.

IMPLICATIONS

  • Given the significant advancements in technology that are likely to continue into the next decades, social work academic leaders and accrediting bodies must be prepared to address the changing landscape of higher education.

  • Social work academics need to become aware and implement best practices in the distance education and online teaching environment to ensure positive student outcomes, student retention, and student engagement to meet the flexibility needs of students in higher education settings.

Annual radiation doses and risks to passengers and crew are calculated for shipments of radioactive materials in passenger aircraft under accident-free and incident-free conditions (i.e., under normal transportation conditions). The 1982 database developed by Sandia National Laboratories is used, and calculations are made using RADTRAN 4.0. This paper is one of two papers estimating radiological risk associated with incident-free transportation of radioactive materials.  相似文献

Patients with Borderline Personality Disorder and adopted emotionally-disturbed adolescents share many personality and psychodynamic characteristics: problems with object loss, separation and abandonment, identity disorders. Emotionally-disturbed adopted adolescents are likely to receive a BPD diagnosis because of 1. unknown genetic or constitutional components, 2. defects in early mothering or chaotic parenting seen in late adoptions, 3. possible misdiagnosis, 4. psychodynamic similarities. Authors caution against the possibility of misdiagnosis because of this environmental reinforcement provided by an adopted status.  相似文献
