Women, particularly undocumented women, are at an increased risk for gender-based violence including intimate partner violence (IPV). Women’s lack of legal immigration status is often used as a tool of dominance and control of undocumented women. The Victim of Trafficking and Violence Prevention Act 2000 created the U-Visa that provides undocumented IPV victims with lawful immigration status if they are willing to assist authorities in investigating crimes. The objective of this study is to better understand the benefits of obtaining the U-Visa from the perspectives of Latina U-Visa recipients who are survivors of IPV. In this community-based qualitative research study involving IPV survivors, community leaders, service providers and academics, we collected qualitative data through interviews with 20 participants including 15 survivors of IPV who were U-Visa recipients. Interviews were digitally-recorded, transcribed and translated, and analyzed using a qualitative software to develop key themes. Women received a $20 gift card as a token of appreciation for their participation in this study. Findings highlight key benefits such as improved mental health, renewed confidence and self-esteem, self-confidence, less perceived exploitation, access to better jobs and housing, freedom to travel, and improved economic and social well-being for visa recipients and their families. Obtaining the U-Visa was a transformative and life-changing experience for Latina survivors of IPV. Social policies such as TVPA help support vulnerable women who are victims of IPV. 相似文献

Consistent with a new genre of research on life-course analyses of health-service use, this study explores the consequences of long-term exposure to a risk factor. Drawing from cumulative-disadvantage theory, the study examines whether obesity, especially chronic obesity, increases hospitalization admission and length of stay. Analyses make use of hospital records abstracted over 20 years from a national survey of adults 41 to 77 years of age at baseline (n = 4,574). Multiple measures of body weight are used to calculate adult obesity duration. Results reveal that obesity increased hospital admissions and length of stay over the 20 years studied. Among persons obese at any time during the study, years of obesity also led to longer stays. The findings highlight the utility of measures of the duration of risk exposure for both life-course studies of health and tests of cumulative-disadvantage theory. 相似文献

Both the findings and the limitations of numeric milestone research in sexology have a bearing on the pedagogical status of pleasure, as well as the cultural underpinnings of the notion of a psychosexual milestone. An overview is offered of international data pertaining to the chronology of three "milestones" in sexual autobiography: first orgasm (orgasmarche), first ejaculation (oigarche), and first wet dream (nocturnal emission). Methodological problems associated with the measurement of these variables are discussed. These problems are then situated in a culturalist perspective. It is concluded that orgasms are cultural artifacts in terms of their chronological occurrence as well as perceived salience, necessity, and "age appropriateness". 相似文献

This study examined whether the efficacy of keepin' it REAL, a model program for substance use prevention in schools, was moderated by gender, ethnicity, and acculturation. Gender differences in program efficacy may arise through boys' higher risk of drug use, inadequate attention to girls' developmental issues, or cultural factors like polarized gender expectations. Data came from a randomized trial in 35 Phoenix, Arizona, middle schools involving 4,622 mostly Latino 7th graders. Using multi-level mixed models and multiple imputation missing techniques, results for the total sample showed no gender differences in program effects on recent substance use, but the program was more effective in fostering boys' than girls' anti-drug norms. Subgroup analyses demonstrated several more beneficial program effects for boys than girls (less alcohol and cigarette use and stronger anti-drug norms), but only among less acculturated Latinos. There were no gender differences in program effects among more acculturated Latinos, nor among non-Latino whites. 相似文献

Domestic violence screening and service acceptance among adult victims in a dependency court setting
Many child welfare systems are unable to effectively identify and address co-occurring domestic violence and child maltreatment. In response, the Dependency Court Intervention Program for Family Violence implemented a protocol to identify indicators of domestic violence in families involved with child protection proceedings. This article highlights data that demonstrate the ability of an outreach and screening process to identify adult victims of domestic violence in dependency court and to offer them appropriate intervention services. 相似文献

As canons for trustworthiness developed explicitly in the discourse of qualitative inquiry, the emphasis was on procedural matters rather than fundamentally relational ones. A nod was made to the relational in such strategies as “member checks” but the issues of how the evaluator actually relates to participants and to the larger communities of practice and discourse—matters subsumed under moral principles and ethical standards—were often marginalized. This chapter posits that the first consideration in designing and conducting rigorous evaluation inquiry, and in critiquing the results of any research, should be the study's trustworthiness. Judging a study's trustworthiness, however, should focus on much more than procedural matters; it should also rely on moral principles and ethical standards which specifically address how we relate to an evaluation's participants. Central to these considerations are cross-cultural sensibilities about the nuanced meanings associated with any principles and standards. The chapter provides a theoretical framework for this position and offers two illustrative examples in the form of dialogues. 相似文献

The ethical work of program evaluators is based on a covenant of honesty and transparency among stakeholders. Yet even under the most favorable evaluation conditions, threats to ethical standards exist and muddle that covenant. Unfortunately, ethical issues associated with different evaluation structures and contracting arrangements have received little attention in the evaluation research literature. This article focuses on the unintended ethical threats associated with multitiered evaluation contexts. After briefly reviewing the various frames through which evaluation theory and ethics are commonly viewed, we discuss ethical challenges associated with multitiered evaluation designs including examples drawn from our evaluation projects. The article concludes with specific findings and recommendations for evaluators, grantors, grantees, and researchers. 相似文献

Auctions provide an institutional solution to a social problem; they enable the legitimate pricing and exchange of goods where those goods are of uncertain value. In turn, auctions raise a number of social and organizational issues that are resolved within the interaction that arise in sales by auction. In this paper, we examine sales of fine art, antiques and objets d'art and explore the ways in which auctioneers mediate competition between buyers and establish a value for goods. In particular, we explore how bids are elicited, co-ordinated and revealed so as to rapidly escalate the price of goods in a transparent manner that enables the legitimate valuation and exchange of goods. In directing attention towards the significance of the social interaction, including talk, visual and material conduct, the paper contributes to the growing corpus of ethnographic studies of markets. It suggests that to understand the operation of markets and their outcomes, and to unpack issues of agency, trust and practice, we need to place the 'interaction order' at the heart of analytic agenda. 相似文献

The assessment of malingering has predominantly been considered within the domains of neuropsychologists and psychiatrists, who use consistency of performance criteria similar to those used in functional capacity evaluations (FCE). The use of activity has traditionally been used in occupational therapy as an assessment and treatment modality with goals not always considered obvious and which could easily be used for diversional reasons. The appropriate use of activity adds an additional dimension to a layered approach of using multiple data sources and methods as recommended by FCE practitioners and neuropsychologists alike. The case illustration aims to explain the above using a layered model. 相似文献

Cue-reactivity has received increased attention in addiction research, though not for gambling in particular. We examined
cue reactivity in 18 problem gamblers by accompanying them to a gaming casino and measuring their subjective urge to gamble
over a 1-h period. Half of the sample was additionally exposed to a gambling-specific negative mood induction (NMI) manipulation
via guided imagery. Overall, about two-thirds of the sample reported moderate to high-gambling urges during the casino exposure.
Additionally, the NMI reduced cue-reactivity. Finally, gambling urges in both groups decreased over the course of the exposure
sessions. These findings suggest that a majority of problem gamblers experience the urge to gamble when exposed to gambling
cues and that the intensity of these urges decrease with time, especially in the presence of a gambling-relevant NMI. Cue
exposure should be studied further as a potential tool in the treatment of problem gambling. 相似文献
