Men with and without sexual dysfunction present with varying patterns of agreement between subjective estimates of sexual arousal and more objective psychophysiological measures of the same construct. This relative accuracy seems to be associated with sexual function, with men who have sexual dysfunction presenting less accurate estimations (mostly reporting below measured arousal levels). The purpose of this study is to clarify the processes underlying sexual arousal and the accuracy of its self-estimation. We looked at potential predictors of sexual arousal (subjective and physiological) and accuracy in estimating objective sexual arousal in a sample of 60 sexually functional males. Predictors included pre-existing sexual attitudes (erotophobia), both trait and state positive and negative affect, self-focused attention, and interoceptive awareness. Results indicate that this sexually functional sample generally reported below their own erection level. Interestingly, trait negative affect was associated with somewhat lower levels of subjective arousal and higher levels of physiological arousal. On the other hand, state positive affect facilitated both subjective and objective arousal and increased somewhat the accuracy of estimates of erectile responding. Pre-existing sexual attitudes as well as variations in self-focused attention and interoceptive awareness evidenced little effect on sexual arousal or the accuracy of its estimation.  相似文献

Sociology and political arithmetic: some principles of a new policy science   总被引:1,自引:0,他引:1  
This paper advances the position that sociology needs to develop an approach to research which focuses on fundamental social problems. In doing so it shares many of the intellectual values and goals of political arithmetic while seeking to move methodologically beyond it. Since such problems are complex they will require, typically, interdisciplinary input and a concomitant approach to the development and appraisal of theories. We are not, therefore, advocating the primacy of sociology but arguing that it has a distinctive part to play in addressing the fundamental problems of the twenty-first century. However, a policy-oriented sociology has also to take up the task, so clearly defined by the tradition of political arithmetic, which is to hold governments to account. Consequently a central principle of a new policy science is that it should contribute to democratic debate about policy.  相似文献

Integrins are cell surface receptors that mediate adhesion to the extracellular matrix. In this Perspective, we focus on the recent finding that a decrease in the levels of integrins yields fruit flies that retain youthful mobility as they age and display an increased mean life span. We discuss how the reduction of integrin activity might lead to the observed changes.  相似文献

OBJECTIVE: The primary objectives of this study were to identify sources of meaning for individuals within the context of a work environment, and to compare varied sources of meaning for individuals with high and low work satisfaction levels. METHOD: Participants were chosen based on satisfaction levels in employment, full-time employment status within an organization for at least one year, and diversity in the work setting. Data were gathered through a series of interviews and observations of the participants' workplaces. A comparative analysis of transcribed interviews was conducted by the researchers and with an expert occupational therapy faculty panel. From these analyses, the researchers developed work narratives for a mechanical engineer, a high school teacher, an employee of mechanical services, and a career service counselor. RESULTS: Emerging themes from the work narratives indicated that the various meanings employees found in work had an effect on their perceived levels of job satisfaction. Participants conveyed that organization identification, financial benefits, independent decision-making, reciprocal respect, opportunities for creativity, and maintaining significant relationships outside of work enhanced meaning and satisfaction. CONCLUSIONS: The worker role is a significant source of an individual's identity, meaning, and satisfaction in life. Professionals in various fields can work with employers to develop meaningful work environments for increased job satisfaction, greater motivation for work, increased productivity, and decreased employee turnover.  相似文献

Volunteer labor is generally modeled as an individualistic pursuit, akin to leisure or to human capital accumulation. Some activities labeled as volunteering, however, may be more usefully thought of as quid pro quo time commitments that are part of securing services for family members. Parents are frequently expected to volunteer, for example, when their children participate in youth sports leagues or school marching bands. In such cases, volunteering is essentially an instance of household production undertaken outside the home. Using data from the Panel Study of Income Dynamics, we divide volunteering into three categories—youth-related, religious, and non-youth-related secular—according to the likelihood that an instance of volunteering in the category represents household production. We find evidence that husbands and wives respond to one another’s time pressures such that youth-related volunteering looks like a task for which husbands’ and wives’ time inputs substitute for one another. Further, we find this pattern for housework, and not for other forms of volunteering. An increase in either spouse’s hours of market work will significantly reduce that spouse’s likelihood of volunteering for youth-related activities while raising the partner’s likelihood of volunteering. A similar pattern holds for hours volunteered to youth-related activities, with the wife’s responses achieving statistical significance.  相似文献

Abstract

Bioethical debates contribute to discussions about the direction of healthcare funding as we enter the twenty - first century. The funding of healthcare is debated by economists, bioethicists and clinicians. Because of their practice experience and knowledge base social workers are also well-placed to contribute to such issues. The debate has taken place at the ‘macro’ rather than the ‘micro’ level. Yet many ethical decisions about healthcare are made at the patient's bedside. Are they procedural or clinical decisions? Are decisions made for a group or class of patient or on an individual basis? Answers for these questions are sought in a study of medical decision-making for head-injured patients admitted to the Intensive Care Unit of a major teaching hospital.

This paper attempts to draw out ethical principles which are part of medical decision-making. The notion of contextual ethics is likened to the ecological approach of Carel Germain which provides a useful framework for ethnomethodological research.  相似文献

ABSTRACT

The aging of the United States population is creating an increased need for social workers and other helping professionals with training in gerontology. Recent estimates indicate that less than 3% of MSW students are enrolled in an aging concentration, as compared to 19% enrolled in children/youth concentrations. In addition, the phenomenon of a diverse baby boomer generation joining the ranks of persons age 65 and older has created a plethora of scholarship and curriculum development aimed at readying the aging network for the unprecedented growth of older persons. Social work can make unique professional contributions to the field of gerontology and older persons. This study asserts, however, that social work is not adequately prepared to practice in an increasingly diverse aging society. The social work profession has articulated commitments to acknowledging and affirming how diversity and culture shape the human experience and to developing social workers who can competently engage in research-informed practice and practice-informed research. However, there remains a need in social work education for more widespread use of culturally relevant pedagogies that can help achieve these goals. Informed by both the Afrocentric and Black perspectives, this study presents a content analysis of the curricula infused at two historically Black universities. The nature and extent of the contributions of historically Black universities to social work education is the focus of this article. The scope of this investigation also includes the identification of prominent Black social work educators and discusses the implications of these perspectives for more culturally informed gerontology curricula that promote culturally competent gerontological social workers.  相似文献

This paper examines rural population ageing in the United States with a particular focus on the contrasting contexts in which older rural residents live. We compare the characteristics of the older population by rural versus urban residence, and explore challenges and opportunities associated with the ageing of rural baby boomers. The United States is a vast territory, and rural areas in the US are diverse regionally, in poverty and income, principal forms of employment, proximity to metropolitan areas, population size, density and composition, the history of change in these parameters, and a number of other factors that affect the ageing process. Hence, the diversity across rural areas is an important consideration in what affects the well being of rural elderly individuals, as well as the community-level impacts of rural ageing. Further, the characteristics of the older rural population help shape community and rural development outcomes for diverse rural communities. We use data from various US Census Bureau sources, and cite other studies to provide a demographic overview of ageing in the rural United States, and to analyze how this situation differs in varying socio-demographic and regional contexts. In the concluding section, we focus on policy implications associated with rural ageing.  相似文献

Input‐output analysis is frequently used in studies of large‐scale weather‐related (e.g., Hurricanes and flooding) disruption of a regional economy. The economy after a sudden catastrophe shows a multitude of imbalances with respect to demand and production and may take months or years to recover. However, there is no consensus about how the economy recovers. This article presents a theoretical route map for imbalanced economic recovery called dynamic inequalities. Subsequently, it is applied to a hypothetical postdisaster economic scenario of flooding in London around the year 2020 to assess the influence of future shocks to a regional economy and suggest adaptation measures. Economic projections are produced by a macro econometric model and used as baseline conditions. The results suggest that London's economy would recover over approximately 70 months by applying a proportional rationing scheme under the assumption of initial 50% labor loss (with full recovery in six months), 40% initial loss to service sectors, and 10–30% initial loss to other sectors. The results also suggest that imbalance will be the norm during the postdisaster period of economic recovery even though balance may occur temporarily. Model sensitivity analysis suggests that a proportional rationing scheme may be an effective strategy to apply during postdisaster economic reconstruction, and that policies in transportation recovery and in health care are essential for effective postdisaster economic recovery.  相似文献
