Triangulation is a comparative strategy for examining data that strengthens qualitative and multi-method research. Despite the benefits of triangulation noted in the research methods literature, few concrete models for operationalization of protocols exist. Lack of documentation of explicit triangulation procedures is especially true in the area of bereavement research. This article describes how an interdisciplinary research team implemented a triangulation protocol in a study of the needs of bereaved parents. Triangulation enabled the integration of diverse data sources, methods, and disciplinary perspectives. These processes yielded a more meaningful typology of bereaved parents' needs than would have otherwise been possible. Extending the use of triangulation will enhance multi-faceted understandings of bereavement. 相似文献

Multistage ranked-set sampling (MRSS) is a generalization of ranked-set sampling in which multiple stages of ranking are used. It is known that for a fixed distribution under perfect rankings, each additional stage provides a gain in efficiency when estimating the population mean. However, the maximum possible efficiency for the MRSS sample mean relative to the simple random sampling sample mean has not previously been determined. In this paper, we provide a method for computing this maximum possible efficiency under perfect rankings for any choice of the set size and the number of stages. The maximum efficiency tends to infinity as the number of stages increases, and, for large numbers of stages, the efficiency-maximizing distributions are symmetric multi-modal distributions where the number of modes matches the set size. The results in this paper correct earlier assertions in the literature that the maximum efficiency is bounded and that it is achieved when the distribution is uniform. 相似文献

Abstract Objective: To assess the use of alcohol screening tools across US colleges. Participants: Directors of health services at 333 four-year colleges. Methods: An online survey was conducted regarding the use of alcohol screening tools. Schools reporting use of formal tools were further described in terms of 4 tools (AUDIT, CUGE, CAPS, and RAPS) that the authors judged to be the most favorable based on prior empirical comparative studies. Results: Forty-four percent of colleges reported use of at least 1 formal alcohol screening tool and nearly all of these used a tool appropriate for college students. However, less than half of the 44% of colleges that used a screening tool used 1 of the 4 most favorable tools. Conclusions: Continued efforts are needed to encourage colleges to use the most effective available screening tools to identify alcohol-related problems that require intervention among students. 相似文献

ABSTRACTElder abuse increases the likelihood of early mortality, but little is known regarding which types of abuse may be resulting in the greatest mortality risk. This study included N = 1,670 cases of substantiated elder abuse and estimated the 5-year all-cause mortality for five types of elder abuse (caregiver neglect, physical abuse, emotional abuse, financial exploitation, and polyvictimization). Statistically significant differences in 5-year mortality risks were found between abuse types and across gender. Caregiver neglect and financial exploitation had the lowest survival rates, underscoring the value of considering the long-term consequences associated with different forms of abuse. Likewise, mortality differences between genders and abuse types indicate the need to consider this interaction in elder abuse case investigations and responses. Further mortality studies are needed in this population to better understand these patterns and implications for public health and clinical management of community-dwelling elder abuse victims. 相似文献

Currently, about 10% of infants have a weight for length greater than the 95th percentile for their age and sex, which puts them at risk for obesity as they grow. In a pilot obesity prevention study, primiparous mothers and their newborn infants were randomly assigned to a control group or a Soothe/Sleep intervention. Previously, it has been demonstrated that this intervention contributed to lower weight‐for‐length percentiles at 1 year; the aim of the present study was to examine infant behavior diary data collected during the intervention. Markov modeling was used to characterize infants' patterns of behavioral transitions at ages 3 and 16 weeks. Results showed that heavier mothers were more likely to follow their infants' fussing/crying episodes with a feeding. The intervention increased infants' likelihood of transitioning from a fussing/crying state to an awake/calm state. A shorter latency to feed in response to fussing/crying was associated with a higher subsequent weight status. This study provides preliminary evidence that infants' transitions out of fussing/crying are characterized by inter‐individual differences, are modifiable, and are linked to weight outcomes, suggesting that they may be promising targets for early behavioral obesity interventions, and highlighting the methodology used in this study as an appropriate and innovative tool to assess the impact of such interventions. 相似文献

ABSTRACTSexual harassment, unlike rape, is a project of leisurely objectification that depends, for its erotic charge, on the perversion of consent. Unlike rape, where consent is vanquished, or erotic mutuality, where it is ratified, the pleasure of sexual harassment is that “consent” is coerced, that is, it is “consent” under duress. Under these conditions, which slowly dismantle the personhood of the victim, the issue becomes one of reality testing. “Just say no” is not an option when the question at hand is “What just happened?” 相似文献

The purpose of this study was to evaluate the efficacy of a school-based case management intervention in reducing teen-pregnancy. A nonrandomized intervention/comparison schools mixed-method evaluation design was employed. Participants included 203 pregnant and parenting teens with annual follow-up over a 3-year period. The results indicated that the time to repeat pregnancy was delayed among pregnant teens, high school drop-out rates were reduced among parenting teens, and pregnant teens were less likely to deliver before 36 weeks in the intervention versus the comparison school. Case management at a school setting is a promising approach to decrease repeat teen pregnancy. 相似文献

ABSTRACTDespite federal and state laws and policies aimed at preventing sexual misconduct by school employees, one in ten American students will experience sexual abuse or misconduct at the hands of a K-12 school employee. To explore why such sexual misconduct continues to occur, this study examined the effectiveness of education policies by investigating whether and how school employees understand these policies, how they are implemented, and how loopholes may undermine their intent. This qualitative case study was conducted in three Virginia school districts and included 46 semi-structured interviews with school district employees and county, state, and federal government employees associated with cases of school employee sexual misconduct, and extensive document analysis of school policies and procedures, laws, and court records. Analyses revealed an absence of policy implementation, demonstrated most seriously by a lack of awareness and understanding of policies among school employees, underreporting, and ineffective data collection. The study also identified a number of loopholes in the implementation of policies, resulting from a mismanaged intergovernmental system. The analysis suggests that understanding and implementation of policies meant to prevent sexual misconduct by school employees are fragmented; this fragmentation may be contributing to the continued prevalence of sexual misconduct by school employees. 相似文献

As many scholars have discussed, when addressing divisive social issues many people immediately assume an adversarial posture, thus lessening the chance for productive dialogues about these issues and lessening the likelihood that people will listen to each other. One area that is keenly affected by our “argument culture” is the classroom; after all, students have been well-conditioned in the “adversary method” before reaching college classes. While some conflict is necessary for growth and learning, when that conflict blocks ideas and discussion, that conflict is not productive. Therefore, in order to make classroom interactions productive and to promote listening, practices by a group from the public sphere—The Public Conversations Project (the PCP)—can be used as a model for encouraging productive dialogues in the college classroom. 相似文献
