This article includes a discussion of elder sexuality, beginning with the problem of categorizing elders. This is followed by considerations of elder sexual practices, physiology, and social-psychological factors in elder sexuality. The article concludes with recommendations for people working with elders in regard to their sexuality.  相似文献

To examine how competition influences resource allocation in 4‐ to 6‐year‐olds, children were assigned to one of two conditions. In the experimental condition children colored a picture for a coloring contest whereas in the control condition they colored a picture to decorate a wall. Subsequently, all children participated in a resource allocation task with another child who was introduced as another participant in the coloring contest or who would also be coloring a picture for the wall. Finally, children were asked how many crayons (out of eight) they wanted to provide to the other child. In the resource allocation task, children made decisions about how to allocate stickers to self and other across four trial types: cost and no cost variations of both advantageous and disadvantageous inequality trials. Children were less prosocial in the experimental condition than in the control condition but only in disadvantageous inequality trials involving a cost. Children in the experimental condition withheld more crayons compared to children in the control condition. These results suggest that competition not only decreases prosocial behavior directly linked to the competition but also decreases generosity when provided with an unrelated resource allocation opportunity.  相似文献

Based on biographical materials of armed militants of the Provisional Irish Republican Army and Red Brigades, this article analyses variation within the micromobilization that leads to armed groups. Three general paths are singled out: the ideological path, the instrumental path and the solidaristic path. Each of these is characterized by complex interactions between the individual motivations for involvement (micro-level), the networks that facilitate the recruitment process (meso-level), and the effects of repression on individuals (macro-level). We discuss the discoveries we have made and conclude by describing the advantages of our approach.  相似文献

This paper describes the development of the Perceived Sexual Control inventory (PSC) and a study investigating the relationship between an individual's perception of control over sexual behavior and actual sexual risk behavior in a New York City cohort of 108 HIV+ and 48 HIV‐ gay men. Correlational analysis indicated that reported difficulty controlling sexual behavior was associated with having more male sex partners and sex occasions over lifetime and in the 6 months prior to interview, with a greater number of one‐time partners and out‐of‐home partners, with less monogamy, and with being abstinent in the prior 6 months. Those who perceived difficulty with sexual control were significantly more likely to use cocaine or amyl nitrate (poppers) during sex, to do so on more occasions and to use more drugs overall. Additionally, perceptions of sexual control were found to relate to high risk sexual practices. Those lower in perceived sexual control reported more occasions of receiving anal ejaculation than those who reported greater sexual control. Two subscales (Perceived Control Over Sex Drive and Perceived Control Over Risk Behavior), derived via factor analysis from the 20‐item inventory used to assess perceived sexual control, were also examined in relation to the above variables, and differential findings are discussed. The overall pattern of findings supports the construct validity of the PSC.  相似文献

A perturbative approach is used to derive approximations of arbitrary order to estimate high percentiles of sums of positive independent random variables that exhibit heavy tails. Closed-form expressions for the successive approximations are obtained both when the number of terms in the sum is deterministic and when it is random. The zeroth order approximation is the percentile of the maximum term in the sum. Higher orders in the perturbative series involve the right-truncated moments of the individual random variables that appear in the sum. These censored moments are always finite. As a result, and in contrast to previous approximations proposed in the literature, the perturbative series has the same form regardless of whether these random variables have a finite mean or not. For high percentiles, and specially for heavier tails, the quality of the estimate improves as more terms are included in the series, up to a certain order. Beyond that order the convergence of the series deteriorates. Nevertheless, the approximations obtained by truncating the perturbative series at intermediate orders are remarkably accurate for a variety of distributions in a wide range of parameters.  相似文献

CHANGE OR DIE. The competitiveness of business companies continuously demands innovative ideas and the willingness to implement these from executive managers. Thereby their own personal needs are often neglected. The consequences range from stress and overload up to burnout symptoms. To support an appropriate handling of the imposed work load by managers, a scientifically grounded stress-tolerance-training will be designed and evaluated. For the first time, certain outdoor exercises will be used specifically among conventional elements as active experiences of challenges outside the office can deeply strengthen the constructive handling of stressful situations.  相似文献

Although prior studies have consistently shown that organizational identification can reduce employees' stress and burnout, little is known about the mediating processes that underlie this relationship. Against this backdrop and building on recent theoretical work on the social identity model of stress, the present research tests a two-step mediation model for the organizational identification–burnout link. Specifically, it is hypothesized that employees who strongly identify with their organization are particularly likely to receive social support from their colleagues. This, in turn, should promote a sense of collective efficacy and, as a consequence, negatively relate to burnout. Data from a study with 192 Italian high schoolteachers supported the hypotheses.  相似文献

Previous research has shown that the number of children, their age and the timing of births relative to marriage are associated with the stability of the parental marital union. The purpose of this study is to investigate the role of children in this multidimensional association as a determinant of disruption in Italy, a country where this research question is particularly interesting because of the traditional vision of the family, in terms of formation and dissolution procedures, family and gender roles, and obligations among family members. The relative risk of marital disruption is estimated using some discrete time event-history models. As expected, the findings show that children born in the marriage have a large protective effect on marital stability, a sizeable portion of which is not due to the children’s age. Conversely, children born out of wedlock do not inhibit marital disruption, but neither do they increase the risk as they do in other countries. This is probably because of the type of reproductive behaviour widespread in Italy.  相似文献

This work presents a new scale to measure conflicting attitudes toward sexual minorities. This scale parallels existing measures of conflicting racial attitudes (anti-Black and pro-Black attitudes; Katz & Hass, 1988). After constructing and validating measures of antigay and progay attitudes, we tested relationships among core American values with racial and sexual minority attitudes. We examined relations among the Protestant Work Ethic (PWE), Traditional Family Ideology (TFI), and egalitarian values with attitudes toward racial outgroups and sexual minorities. The results revealed that both PWE values and egalitarian values predicted anti-Black attitudes. By contrast, endorsement of egalitarian values, but not PWE values, predicted pro-Black attitudes. Results also revealed a similar but distinct pattern among values and heterosexuals' attitudes toward sexual minorities. TFI, but not egalitarian value endorsement, predicted antigay attitudes, whereas both TFI and egalitarian value endorsement predicted progay attitudes. The implications of these findings are discussed.  相似文献
