Over the past decade, US states have responded to federal inaction on comprehensive immigration reform by increasing their output of immigrant policies, both beneficial and restrictive. Although there is a growing empirical literature focused on predicting such activity by states, less is known, especially on a broad scale, about the state-level consequences associated with the policy tone states adopt toward immigrants. To better understand the consequences of restrictive immigrant policies, we created a restrictive score for each state year between 2005 and 2014 and employed linear regression with panel-corrected standard errors to investigate effects on immigrant-related demographics, economic factors, and political participation. We found that states with higher restrictive policy tones do experience reductions in the number of foreign-born residents, including Hispanics and those with limited English proficiency, a goal of many state legislators who favor restrictive policies. States with restrictive policy tones showed reductions in unemployment and poverty rates as well, which are also professed goals for restrictive policy activity. Mediation analyses suggested that the effects of restrictive policy scores on economic conditions are indirect, being exerted through the percentage of a state’s population that is foreign born. Finally, though much attention is focused on the expected increase in Latino political clout, restrictive policy tone was not predictive of increased voter registration or voting in states that pass these types of policies. If anti-immigrant policies are inducing those who oppose these policies to mobilize politically, it must be in an arena outside of voting. 相似文献

Turner syndrome (TS) is a genetic disorder, affecting 1/2500 to 1/3000 live female births, induced by partial or total deletion of one X chromosome. The neurocognitive profile of girls with TS is characterized by a normal Verbal IQ and weaknesses in visual-spatial, mathematics, and social cognitive domains. Executive functions (EFs) impairments have also been reported in these young patients. However, methodological differences across studies do not allow determination of which EFs are impaired and what is the magnitude of these impairments. The aim of this review was to clarify the EF profile of children and adolescents with TS. Sixteen samples, from thirteen studies, were included in the current meta-analysis. EFs measures used in these studies were classified into working memory, inhibitory control, cognitive flexibility, or higher-order EFs tasks in accordance with Diamond’s model, Annual Review of Psychology, 64, 135–168 (2013). Results confirmed that girls with TS had significant executive impairments with effect sizes varying from small (inhibitory control) to medium (cognitive flexibility) and large (working memory, higher-order EFs). Analyses by task revealed that cognitive inhibition may be more impaired than the other inhibitory control abilities. Heterogeneity across cognitive flexibility measures was also highlighted. Between-sample heterogeneity was observed for three tasks and the impact of participants’ characteristics on EFs was discussed. This meta-analysis confirms the necessity to assess, in patients living with TS, each EF by combining both visual and verbal tasks. Results also underline that, when studying girls with TS’ executive profile, it is important to explore the impact of moderator variables, such as IQ, parental socio-economic status, TS karyotype, psychiatric comorbidities, and hormonal treatment status. 相似文献

The current practice of cancer genetic counseling is undergoing widespread change and scrutiny. While there are clinical resources for genetic counselors (GCs) regarding the delivery of cancer genetic services, there is limited literature regarding effective management of a genetic counseling clinical program. We have developed administrative tools to manage a large team of GCs at a single academic medical center over a period of increasing demand for genetics services, with the initial aim of decreasing wait time for urgent genetic counseling visits. Here, we describe the three main elements of the clinical operations: Balancing patient volume between GCs, scheduling tracks for both routine and urgent appointments, and a team of triaging GCs to ensure appropriate patient referrals. For each of these elements, we describe how they have been modified over time and present data to support the utility of these strategies. The preliminary evidence offered here suggests that these tools allow for an equitable distribution of patient volume between team members, as well as the timely and accurate scheduling of urgent patients. As a result of the experiences presented here, other genetic counseling programs grappling with similar issues should be aware that it is possible to shift clinical operations to serve certain patient populations in a more timely fashion while keeping both providers and GC staff satisfied. 相似文献

While the devastating effects of parental alcohol use on children’s health are well known, the specific impact of childbirth on parental alcohol consumption has rarely been examined in the general population. We sought to examine patterns of alcohol use associated with childbirth. Data were drawn from the US National Epidemiologic Survey on Alcohol and Related Conditions. We compared successively the characteristics of alcohol use among females living with a child under 1 year with (i) those of females not living with children under 1 year and (ii) those of females living with an older child. Mean daily ethanol intake was lower among females living with a child under 1 than among females either not living with children under 1 year (p?<?0.001) or living with an older child (p?<?0.01). Moreover, low-to-mild drinking frequencies fell among females living with a child under 1, compared with females either not living with children under 1 year (adjusted odds ratio (AOR)?=?0.56; 95% CI [0.40, 0.80] for at least once a month and AOR?=?0.40; 95% CI [0.27, 0.58] for less than once a month) or living with an older child (AOR?=?0.52; 95% CI [0.36, 0.75] for at least once a month and AOR?=?0.66, 95% CI [0.46, 0.94] for less than a month). No significant difference was found for males. Our study suggests that childbirth, as opposed to motherhood per se, reduces several (though not all) dimensions of alcohol consumption in females, but not in males. 相似文献

ABSTRACTAlthough Asian Americans are diverse in many ways, such as language, culture, ethnicity, religion, generational status, and more, many share a common experience: that of having experienced war first hand or being progeny of war survivors. World War II, the Korean War, the Vietnam War, the Cambodian genocide, along with centuries of oppressive and authoritarian rule, have brought experiences of trauma, directly and historically, to the lives of many Asians. Subsequent experiences of migration and resettlement, as well as life in the United States as an ethnic minority, have also compounded the layers of oppression for many Asian Americans. Sexism in our cultures of origin, as well as sexism in the U.S., represents additional realities and traumas faced by Asian American women. In this article, we explore the experiences of war and subsequent traumas in the lives of Asian American women. We present a brief review of the current state of mental health as it relates to the experiences of war trauma, with the goal of providing a crucial contextual backdrop for our review of the best practices in mental health services to Asian American women. We review some of the best practices and conclude with a narrative reflection based on our own involvement in a small professional women’s group that yielded insights, discoveries, healing, and empowerment from the legacy of war trauma. 相似文献

The aim of the present study was to evaluate the equivalence of the French-Canadian version of the Adult Self-Report (ASR; Achenbach & Rescorla, 2003) to its original English (USA) version. Both the original English version and the newly translated French-Canadian version were administered to 251 bilingual students from four Canadian provinces (Manitoba, New-Brunswick, Ontario, and Quebec), with a one to two weeks interval. Correlations varying from 0.72 to 0.87 indicated a high degree of correspondence between the scales of the two versions. Cohen's d calculated using Morris and DeShon's (2002) formula for within-subjects designs indicate that differences between mean scores varied from near-zero (d = 0.01) to small (d = 0.19), and suggest that they are not clinically significant. Ordinal alpha coefficients for the scales of the French-Canadian version varied from 0.66 to 0.96 but are inferior to those of the English version in seven of the eleven scales. Globally, results indicate that the equivalence of the French-Canadian version to the original English version of the ASR is sufficient to recommend its use. 相似文献

This study investigated a new direction for improving the decision making of populations at risk in the context of uncertain environmental events, such as volcanic hazards. According to the risk as feelings theory and dual process models, situations with certain outcomes do not necessarily require the use of affect heuristics (e.g., experienced feelings, anticipated emotions) as valid information in the decision‐making process. In the case of difficult decisions with moral dilemmas, certainty could even improve decisions. Thus, using an ecological design with various scenarios depicting upcoming volcanic hazards, we examined whether reducing the uncertainty of lethal threat by conveying certainty in an information campaign could influence decision making and promote a better quality of choice (correct application of the recommendations from the competent authorities). We focused specifically on two populations composed of local people living in the vicinity of an active volcano (Tungurahua volcano, Ecuador) and local scientists. We also examined whether a difficult decision involving a moral dilemma (e.g., leaving people behind so as not to jeopardize one's own life) potentiated this effect, compared to a less difficult situation without a dilemma. We demonstrated that, for local people facing a moral dilemma (difficult decision), the reduction of uncertainty of lethal threat involved a better application of the actual recommendations. These outcomes provided perspectives on improving the applications of the recommendations among local populations at risk in the context of a real risk exposure. 相似文献
