This paper first introduces a parametric model for the generation of stationary random correlated binary sequences. The parameters of the model include the probability that a pixel is a binary one pixel and the length of the structuring element which dilates the initially spatially uncorrelated sequence. The spatial statistics of such eroded, dilated, opened and closed correlated binary sequences are derived in terms of the spatial statistics of the input binary sequence. Understanding of such one-dimensional processing is a precondition for understanding what happens in the more interesting two- dimensional case. 相似文献

The synthetic np chart is a combination of the np sub-chart and the conforming run length sub-chart. A procedure for the optimal design of the synthetic np chart is provided by minimizing the out-of-control median run length (MRL). The comparative results show that the synthetic np chart performs better than the corresponding standard np chart for detecting process shifts in the fraction non conforming, in terms of the MRL. An example is given to illustrate the operation of the synthetic np chart. 相似文献

College women are at a high risk of sexual assault. Although programs that aim to change bystander behaviors have been shown to be potentially effective in preventing sexual assault on campuses in the United States, little is known about bystander behaviors outside of the United States. The purpose of this study was to explore and compare factors affecting bystander behaviors regarding sexual assault intervention and prevention among undergraduate students in the United States, Japan, India, Vietnam, and China. A total of 1,136 students participated in a self-reported survey. Results demonstrate substantial variations across countries. Bystander behaviors are associated with multilevel factors, including gender, knowledge of individuals who have experienced a sexual assault, and knowledge about campus or community organizations. 相似文献

The positive relationship between income and health is well established. However, the direction of causality remains unclear: do economic resources influence health, or vice versa? Exploiting a new source of exogenous income variation, this study examines the impact of the Alaska Permanent Fund Dividend (APFD) on newborns' health outcomes. The results show that income has a significantly positive, but modest effect on birth weight. We find that an additional $1,000 ($2,331 in 2011 dollars) increases birth weight by 17.7 g and substantially decreases the likelihood of a low birth weight (a decrease of around 14% of the sample mean). Furthermore, the income effect is higher for less‐educated mothers. Based on a gestation‐weight profile in the sample, increased gestation owing to the APFD could explain a maximum of 34%–57% of the measured weight increase, although we are unable to examine all the potential mechanisms.

Individual differences have been a part of leadership research since the days of trait theory. There has been an upsurge in interest in the topic due to recent theoretical and methodological advances. Also, there is increasing interest in measuring individual leader differences using nontraditional methods such as the quantitative analysis of archival data. We describe a general methodology for developing and validating measures of leader individual differences based on computerized language analysis of archival data. Two empirical examples focusing on narcissism among Fortune 100 CEOs illustrate the methodology. We summarize prospects and problems of computerized content analysis of archival materials. 相似文献

This study attempted to explore and clarify the ambiguity surrounding cultural concepts, broaden and deepen the current understanding of cultural competency, and operationalize its core components in multicultural education in the United States. The research findings presented in this study were organized into three overarching themes: Level I: knowledge development; Level II: integrative processes; and Level III: practice evaluation. The findings contributed to the formulation of levels in multicultural learning and to the specification of core cultural components in clinical practice. 相似文献

This study examines the experiences of young people with disabilities from ethnic minorities, and their families, in central Vietnam. The study is set in an area contaminated by Agent Orange during the Vietnam War. Data were gathered from interviews with youth with disabilities and interviews and focus groups with mothers who had children with disabilities. Respondents expressed confronting multiple barriers to inclusion, education, health and well-being similar to other persons with disabilities and their families from around the world. Participants sought broad-ranging human rights as they described experiencing stigmatization and marginalization from negative social reaction toward disabilities and by residing in a location known for dioxin contamination. The participants’ voices are not only important in informing program responses to support implementation of Vietnam’s new National Law on Persons with Disabilities, but also timely as the US government considers proposed legislation providing material support for Vietnamese nationals affected by Agent Orange. 相似文献

The methodological issues of using self-reported human immunodeficiency virus (HIV) testing history to determine HIV infection status are understudied. This study aimed to assess the disparities between HIV testing history and self-reported HIV status, with a specific objective of estimating the prevalence of self-reported HIV-negative status in sexually active students who had never had an HIV test (inaccurate self-disclosure). Participants were recruited from four Hong Kong universities; 255 students were included in the analysis, with 16.1% of participants being men who have sex with men (MSM). Overall, 81.6% of participants reported they never had been tested for HIV, with inaccurate self-disclosure by 65.9% of participants. Among participants who used condoms inconsistently, only 20.2% had had HIV tests, with inaccurate self-disclosure by 66.7% of subjects. Among MSM students, only 36.6% had had HIV tests, with inaccurate self-disclosure by 61.0% of participants. Among MSM students who used condoms inconsistently, only 35.1% had had HIV tests, with inaccurate self-disclosure by 62.2% of participants. The findings raise concerns about the use of self-reported HIV status in clinical practice and research. The low prevalence of HIV testing found suggests that interventions to promote HIV testing should be continued. 相似文献
