Findings, issues, and lessons learned about program evaluation are examined from a national qualitative study of 15 faith-based human service programs targeting those in need in urban areas. Using a grounded theory design, five properties emerge as part of the evaluation network: (1) philosophy of accountability, (2) legitimacy, (3) evaluation design, (4) feedback loop, and (5) barriers to evaluation. While funders expect measurable outcomes to evaluate service effectiveness, respondents acknowledge other competing expectations of multiple constituents in religious and secular communities. What emerges is an excellent example of managing multiple program evaluation demands in programs that are particularly facile at process evaluation in the interest of quality service and relationship building. The article concludes with important lessons learned about the process of program evaluation.  相似文献

Participants (80 men, 80 women) read hypothetical date rape scenarios, wherein the perpetrator's socioeconomic status (bus driver versus doctor) and the victim's level of resistance (verbal versus verbal and physical) were varied, and made judgments about who was at fault and what the consequences should be. In general, men assigned more blame to the victim and less blame to the perpetrator than did women. However, men assigned more blame to the bus driver than to the doctor. Women, on the other hand, assigned more blame to the victim who was raped by the bus driver than to the victim who was raped by the doctor. The results also indicated that participants recommended harsher punishments for the perpetrator when the victim resisted verbally than when she resisted verbally and physically. Future research on the role of the perpetrator's, the victim's, and the participants' socioeconomic status in judgments about date rape is suggested.  相似文献

Correctional institutions are obligated to provide end-of-life care to a population with complex medical needs. Prison hospices are increasingly being formed to address this demand. Few empirical studies have examined the impact of caring for dying inmates on the hospice inmate volunteers, who, in several prison health care systems, provide direct care. In this study, experiences of the inmate hospice volunteers with death were investigated to illuminate their grief processes. Understanding the bereavement needs of hospice volunteers and how prison hospice volunteers navigate grief and remain committed to providing excellent hospice care can inform the grief processes and practices of hospice care professionals.  相似文献

I argue that family scholars must take bolder steps to engage the tensions between our heritage of positivist science and its postmodern challenges. I also argue that constructing theories, utilizing research methods, and examining substantive issues should be relevant to the diversity of the families we study and to ourselves as members of families. I offer examples of developing an informed reflexive consciousness to broaden the rationalist foundation that dominates family scholarship. For a more inclusive, balanced, and invigorated family studies, our subjective experiences and commitments as researchers should be acknowledged, confronted, and integrated. A family studies that is responsible to our readers, students, selves, and the people whose lives we study requires that we engage the critical intersections of race, class, gender, sexual orientation, and age as they define family diversity.  相似文献

Using family systems theory, this longitudinal study of middle school youth examined the effects of abuse, family conflict, and sibling aggression on sexual harassment perpetration (N = 1563; Mage 11.2, 51% boys; 39% Hispanic, 29% Black, and 19% White). Boys reported more sexual harassment than girls; perpetration increased for both. The association between a hostile home environment and sexual harassment perpetration was moderated by school experiences. School belonging buffered effects of hostile home environment on baseline sexual harassment perpetration for boys who experienced abuse and White adolescents with high sibling aggression. Academic grades moderated change in perpetration over time, but effects differed by sex and race. It is important to understand how early violence exposures relate to sexual violence perpetration during early adolescence.  相似文献

A decision regarding development and introduction of a potential new product depends, in part, on the intensity of compeitition anticipated in the marketplace. In the case of a technology-based product such as a personal computer (PC), the number of competing products may be very dynamic and consequently uncertain. We address this problem by modeling growth in the number of new PCs as a stochastic counting process, incorporating product entries and exits. We demonstrate how to use the resulting model to forecast competition five years in advance.  相似文献

As new technologies permit the generation of hitherto unprecedented volumes of data (e.g. genome-wide association study data), researchers struggle to keep up with the added complexity and time commitment required for its analysis. For this reason, model selection commonly relies on machine learning and data-reduction techniques, which tend to afford models with obscure interpretations. Even in cases with straightforward explanatory variables, the so-called ‘best’ model produced by a given model-selection technique may fail to capture information of vital importance to the domain-specific questions at hand. Herein we propose a new concept for model selection, feasibility, for use in identifying multiple models that are in some sense optimal and may unite to provide a wider range of information relevant to the topic of interest, including (but not limited to) interaction terms. We further provide an R package and associated Shiny Applications for use in identifying or validating feasible models, the performance of which we demonstrate on both simulated and real-life data.  相似文献

We merge marital history data for respondents in the National Survey of Families and Households with census data describing the sex composition of their local marriage markets and occupations to examine the impact of the availability of spousal alternatives on marital dissolution. Proportional hazards regression models that adjust for left truncation reveal that the risk of divorce is highest in geographically defined marriage markets where either husbands or wives encounter numerous alternatives to their current partner. Couples are also more likely to divorce when the wife works in an occupation having relatively many men and few women, but husbands' occupational sex ratio has no effect on the risk of marital dissolution. The destabilizing effects of the availability of spousal alternatives in the local marriage market and in wives' occupations are equally strong among couples with many and few other risk factors for divorce. Our findings suggest that spouses' structural opportunities to form alternative opposite‐sex relationships are an important factor in explaining why some couples divorce.  相似文献

Abstract Local environmental groups, although acknowledged increasingly since the mid‐1980s, have not been sampled systematically, have been reported to consist of only a few types, and are often considered to be of only minor political significance. In this study we systematically inventoried all local environmental groups in two U.S. geographical areas: the Delmarva Peninsula and the state of North Carolina. We found 566 local groups, seven to 20 times the number reported in the best published directory. Three‐quarters did not fit the types most commonly characterized in the literature. Extrapolating from our study areas, we estimate that 16,000 to 30,000 local environmental groups are active in the United States. We find that these groups have a subset of “core” members, those active in organizing and local operations. We estimate the population of core members at 265,000 to 290,000, over 50 times the total of professional staff members of all U.S. national environmental organizations. These groups affect local and state environmental policy, enforcement of environmental laws, the shaping of environmental issues, and the social infrastructure for environmental behaviors.  相似文献
