Theory and research on partnered parents suggests trade-offs between parenting and sexuality, with those trade-offs most pronounced among mothers of young children. However, little research has focused on how a growing demographic of single parents negotiates dating and sexual activity. The current study drew upon a 2012 nationally representative sample of 5,481 single Americans 21 years of age and older, of whom 4.3% were parents of a child age five or younger. Dependent variables were sexual thoughts, frequency of sexual activity, number of sexual partners in the past year, dates during the previous three months, and whether one was actively seeking a relationship partner. Covariates included parental age, sex/gender, sexual orientation, education, and income. Using the entire sample of singles, we found no main effects of number (0, 1, 2+) of children aged five years and younger or number of children aged two years and younger on dating and sexual behavior variables. Next, using analyses restricted to single parents (n = 2,121), we found that single parents with a child aged five years or younger, adjusting for covariates, reported greater frequency of sexual activity and first dates but no differences in other outcomes compared with single parents of older children.  相似文献

This paper explores the experiences of social work students on qualifying degree programmes in the UK who have previously been in care or ‘looked after’. Using a sample drawn from three social work programmes in the North West of England, a semi-structured interview schedule was constructed, with the support of social workers who had been in the care system, to examine the individual journeys of 11 students. This paper aims to explore, with this group of students, how their experiences relate to their decision to apply for a place on a social work course, their experience of admission and the duration of the programme. The paper is of particular relevance to social work educators and makes specific suggestions regarding how current practice in social work education might improve.  相似文献

This qualitative case study aimed to explore environmental circumstances and interactional processes that appeared to be relevant for the dynamics of resilience in adolescents exposed to child abuse. Fieldwork at a learning and coping centre for children and their families was combined with semi-structured interviews with adolescent participants aged 12 to 18 years. A critical realist approach was used to unpack what has been called the ‘ordinary magic’ of resilience. We found that intensively validating qualities of both the environment and relationships seemed to be driving components for resilience. Borrowing ideas from the sociometer theory, we propose that particularly the consistent intensiveness may offer a recalibration of the adolescents' immediate life-worlds, in terms of how they perceive the people they meet and the environments they step into. In keeping with the transactional-ecological model of resilience, we suggest that such a recalibration leads to altered social agency that becomes visible through their immediate social participation.  相似文献

This article reports the results of a telephone survey (n = 1002) conducted in November 2008, which aimed to identify parenting stress and perceived family functioning of Chinese parents in Hong Kong; to explore the effects of the parents’ socio‐demographic characteristics (gender, family income, education and family structure) on the aforementioned stress and functioning variables; and to examine the interrelationship among these characteristics and the two variables in question. Results showed that the reported parenting stress was at average level, while the perceived family functioning was slightly below average. The results also indicated that the parenting stress of mothers, single parents, the low‐income and the less‐educated was higher than that of fathers, parents of nuclear and extended families, the high‐income and the better‐educated. Socio‐demographic characteristics except the parent’s gender had similar effects on perceived family functioning. Higher parenting stress was associated with lower family functioning, and explained a larger variance in the perceived family functioning than the socio‐demographic characteristics taken alone. The results of the study have provided empirical support regarding the interrelationships among the vulnerable groups in society, parenting stress and perceived family functioning. Implications of the study for social work practice are discussed.  相似文献

We examine the issues concerning the legality and ethicality of the Second Amendment right to bear arms balanced by the employer's duty to provide a safe workplace for its employees. Two court rulings highlight this balancing act: McDonald et al. v. City of Chicago et al. and District of Columbia v. Heller. “Stand Your Ground” and “Castle Doctrine” laws in the recent Trayvon Martin shooting on February 26, 2012 are also applicable. Various ethical frameworks examine the firearms debate by viewing the Second Amendment from three perspectives. These include a pro‐gun perspective drawing upon libertarianism and fundamental rights; a moderate gun perspective drawing upon consequentialism and stakeholder theory; and finally, an anti‐gun perspective drawing upon a Public Health Ethics and peace ethics approach. We explore the issue of gun control from a business perspective as employers face ethical decisions in responding to legislation that allows guns in the workplace and/or in employer parking lots while still being responsible to provide a safe workplace for their employees. We make recommendations regarding how companies should manage by proactively avoiding legal challenges to employees' rights to own and carry guns into the workplace. This includes emphasis on enhanced security, Human Resource policies and monitoring rapidly changing laws.  相似文献

Research on learning effects in mathematical programming models for optimum resource allocation has called attention to the difficulty in solving such models in their original nonlinear form. In this paper, systematically varying sizes of linear segments are designed to approximate productivity changes along the learning curve, and a single separable linear programming model is developed. With production complementarity and learning transmission between products, a more realistic resource allocation and production scheduling problem emerges. Two cases of learning transmissions are considered, and the model design process, which defines a decision problem that can be solved by a simplex algorithm, is demonstrated.  相似文献
