Substance use often begins earlier among American Indians compared to the rest of the United States, a troubling reality that puts Native youth at risk for escalating and problematic use. We need to understand more fully patterns of emergent substance use among young American Indian adolescents, risk factors associated with escalating use trajectories, and protective factors that can be parlayed into robust prevention strategies. We used growth mixture modeling with longitudinal data from middle-school students on a Northern Plains reservation (Wave 1 N = 381, M age at baseline = 12.77, 45.6 % female) to identify subgroups exhibiting different trajectories of cigarette, alcohol, and marijuana use. We explored how both risk (e.g., exposure to stressful events, deviant peers) and protective (e.g., positive parent–child relationships, cultural identity) factors were related to these trajectories. For all substances, most youth showed trajectories characterized by low rates of substance use (nonuser classes), but many also showed patterns characterized by high and/or escalating use. Across substances, exposure to stress, early puberty, and deviant peer relationships were associated with the more problematic patterns, while strong relationships with parents and prosocial peers were associated with nonuser classes. Our measures of emergent cultural identity were generally unrelated to substance use trajectory classes among these young adolescents. The findings point to the importance of early substance use prevention programs for American Indian youth that attenuate the impact of exposure to stressful events, redirect peer relationships, and foster positive parent influences. They also point to the need to explore more fully how cultural influences can be captured.  相似文献

The present study takes a motivational perspective that views youths’ educational and career engagement as influential and potentially competing for the same motivational resources in the transition to adulthood. We investigated whether motivational engagement with educational and career goals in the year after high-school graduation was differentially associated with educational, career-related and subjective well-being outcomes 2 and 4 years after school graduation. Our longitudinal study of a multi-ethnic sample of Los Angeles high-school graduates followed participants 2 years (N = 561; 61.5 % female) and 4 years (N = 364; 59.8 % female) after high school graduation. The findings indicate that motivational engagement with educational goals after high school graduation predicted educational attainments and psychological well-being at follow-up 2 and 4 years after graduation, and occupational progress at 4 years after graduation. Work hours assessed shortly after high school graduation were associated with poorer educational outcomes both at 2 and 4 years after high school. Occupational goal engagement was not associated with better outcomes, but predicted less educational attainment 4 years after graduating. Thus, educational goal engagement predicted favorable outcomes, whereas career-related goal engagement for the most part was neutral with some select associations with negative educational outcomes. A strong motivational commitment to educational goals, but not to career goals, is an important component of a successful transition to adulthood.  相似文献

Despite calls by some commentators for disclosing incidental findings in genetics research, several factors weigh in favor of caution. The technology of genetics has the power to uncover a vast array of information. The most potent argument for restraint in disclosure is that much research is pursued without consent so that the individual participant may not know that research is being conducted at all. Often the work is done by investigators and at institutions with which the person has no prior contact. Past practice is also relevant; genetics researchers historically have chosen not to disclose incidental findings, of which misattributed paternity and pleiotropic alleles such as ApoE have been the most common. Many people choose not to have genetic tests when given a choice. It may be desirable to discuss the topic of incidental findings when consent for research is obtained, but given the risk of unwanted surprise when there has been no prior discussion, the potential utility of incidental findings should be very high before they are even offered to individuals.  相似文献

Kratom is a plant material exhibiting both analgesic and stimulant effects and is also forensically relevant since it is abused as a “legal high.” It is regulated in several countries but not scheduled in the United States at the federal level. This study used inductively coupled plasma–mass spectrometry (ICP–MS) to measure the concentrations of 13 elements in 19 kratom samples obtained from an online distributor selling kratom, from Borneo, Malaysia, Indonesia, Thailand, and Vietnam, for the purpose of using the elements to discriminate among purported country of origin, “suborigin,” and strain. Analysis of variance revealed statistical differences in concentrations of elements from each group, while discriminant function analysis (using leave-one-out classification) successfully classified kratom samples by their purported country of origin (100%), “suborigin,” (100%), and strain (86%). Our method illustrates the possibility of utilizing ICP–MS for determination of commercially available kratom samples by purported origin, “subororign,” or by product line.  相似文献

If the COVID-19 pandemic has taught us anything, it is that policy makers, experts, and public managers need to be capable of interpreting comparative data on their government's performance in a meaningful way. Simultaneously, they are confronted with different data sources (and measurements) on COVID-19 without necessarily having the tools to assess these sources strategically. Because of the speed with which decisions are required and the different data sources, it can be challenging for any policy maker, expert, or public manager to make sense of how COVID-19 has an impact, especially from a comparative perspective. Starting from the question “How can we benchmark COVID-19 performance data across countries?,” this article presents important indicators, measurements, and their strengths and weaknesses, and concludes with practical recommendations. These include a focus on measurement equivalence, systems thinking, spatial and temporal thinking, multilevel governance, and multimethod designs.  相似文献

Quantitative studies of children’s caring activities during parental illness have increased in the past 10 years. However, the various outcomes for these children have been investigated less frequently. In the present study, we investigate whether the children have different outcomes when the parent has a severe physical illness, mental illness, or substance abuse and whether any factors are associated with the positive and negative outcomes of the children’s caregiving. This was a cross-sectional, multicenter study. We recruited parents who were out- or inpatients in five public hospitals in Norway as well as their children. The sample included 246 children ages 8–18 and 238 of their parents with a severe physical illness, mental illness, or substance abuse. Ten percent reported negative outcomes at a clinical level of concern, and nearly half of the children reported stress. However, the outcomes were not significantly different across parental illness groups. Positive and negative outcomes were associated with the nature of caring activities (e.g., personal care, financial and practical management, household management), social skills, and perceived external locus of control. Health professionals must provide a more comprehensive and overall assessment of both the parents’ and the children’s needs. To recognize the role taken by the child, an assessment of children’s caring activities and their need for adequate information should be performed. In particular, should the children’s need for follow-up regarding caring activities, respite, and emotional support be assessed to secure their necessary skills and feeling of mastery.  相似文献

After Slovakia and the Czech lands separated in 1993, concerns arose regarding Slovakia's ethnic Hungarian, or Magyar, minority. There were concerns about the Slovak government's attitude toward its considerable Magyar population as well as worries about the Hungarian government's stance regarding Magyars in Slovakia and the Slovak-Hungarian border. Frequently over the past decade, the topic of the Hungarian minority in Slovakia has been manipulated by politicians. In both Slovakia and Hungary, Slovak and Hungarian politicians alike have tried to expose “injustices” or “excesses” for political gain. Indeed, the maneuvering of national politicians might lead one to perceive that the reality of contemporary Slovak-Magyar relations was tenuous and acrimonious. But politics aside, what does the average Slovak think of the Magyar minority and Magyar-Slovak relations generally? To what extent do the political debates encompass their actual concerns and deeply held views? In June 2002, I visited Slovakia and pursued these questions in a series of informal interviews with an ad hoc sample of natives, aged 28 to 78. Among them were bankers, administrators, educators, small business owners, doctors, tour guides, taxi drivers, accountants, and one retiree. My quest to find out what ordinary Slovak citizens think about Slovak-Hungarian relations explored both long-held perceptions and present-day thinking. Very often I discovered a marked divergence between perception and reality where the Hungarian minority was concerned. Slovakia is home to a variety of non-Slovak cultures and languages, including Czech, Ukrainian/Ruthenian, and Romany (gypsy). But the largest cultural and linguistic minority are the c. 600,000 Hungarians, who comprise 11% of the population overall and up to 87% in certain towns and villages in southern Slovakia. For example, a 1994 report by the British Helsinki Human Rights Group (BHHRG) lists the southwestern Slovak towns of Dunajska Streda and Komarno as 87.26% and 72.27% Hungarian, respectively.  相似文献
