Objective: This study evaluated the mental health characteristics and beliefs of student service members/veterans (SSM/Vs) who have been exposed to another’s death by suicide.
Participants: A total of 39 SSM/Vs exposed to suicide and 32 SSM/Vs not exposed to suicide were sampled from a larger, epidemiological survey. An age- and gender-matched group of 39 civilian (C) students was drawn from a larger sample of individuals exposed to suicide.
Methods: Data were collected as part of an Internet-based, campus needs survey that occurred in Fall 2014. Participants were asked to complete measures about suicide-related behaviors, suicide prevention, help-seeking, and demographics.
Results: SSM/Vs exposed to suicide had more positive mental health/suicide prevention beliefs than SSM/Vs not exposed to suicide. Cs exposed to suicide were not significantly different from either group. Unique help-seeking patterns were also identified.
Conclusions: The current study identifies unique characteristics of SSM/Vs exposed to suicide that may inform prevention programming. 相似文献
This is the first study to investigate the trend of adopted individuals from China who search for and reunite with their birth parents. The authors suggest that the closed nature of China's international adoption program and growing ethical concerns about children's true origins impact the desire to search. Due to the generally younger ages of Chinese adoptees, adoptive parents have taken an unprecedentedly proactive role in this process. This article relies on in-depth interviews with adopted children and adoptive parents from seven Western families who reunited with Chinese birth parents. Interviews focused on the decision to search and methods used; the initial reunion; the development of bonds between adoptive and birth families; and post-reunion views of searching. 相似文献
Experimental designs are widely used in predicting the optimal operating conditions of the process parameters in lifetime improvement experiments. The most commonly observed lifetime distributions are log-normal, exponential, gamma and Weibull. In the present article, invariant robust first-order rotatable designs are derived for autocorrelated lifetime responses having log-normal, exponential, gamma and Weibull distributions. In the process, robust first-order D-optimal and rotatable conditions have been derived under these situations. For these lifetime distributions with correlated errors, it is shown that robust first-order D-optimal designs are always robust rotatable but the converse is not true. Moreover, it is observed that robust first-order D-optimal and rotatable designs depend on the respective error variance–covariance structure but are independent from these considered lifetime response distributions. 相似文献
This study investigated the relationship between language performance and cognitive function in stroke patients after nondominant hemisphere damage. The results of a battery of formal language tests, K-WAB, of seventy-eight patients were analyzed. The correlation between their K-WAB and K-MMSE scores was analyzed. Multivariate analysis of covariance adjusting for educational years in each of K-WAB and K-MMSE was conducted in accordance with the brain lesion location. Only 35.9 % of patients were classified as normal and the remaining 64.1 % were categorized as subnormal by K-WAB. There was a positive correlation between their language and cognitive functions. Outcomes differed according to lesion location, as the SAH group exhibited a significantly lower performance in both language and cognitive evaluations than the other groups. Cognitive-communicative disorders in stroke patients with nondominant-hemispheric lesions present in different ways. In-depth language evaluation of all brain-damaged patients should be conducted so that language defects of patients are not ignored. 相似文献
Although face-to-face events starring film professionals have become increasingly popular, they have rarely been studied, especially from the perspective of production. Focusing on the phenomenon of Chinese movie roadshows, this study explores the motivations and techniques used to produce popular media events in the Chinese film industry. Based on expert interviews with 15 media practitioners, the results showed that roadshows are staged as ritualized events that are centered on the performance of a symbolic boundary between “inside” and “outside” the media. Film industry professionals embrace face-to-face communication with audiences and use such events to display sincerity, producing them as a seemingly “unmediated” peek behind the veil of an otherwise hidden world. Moreover, communication on social media is another form of ritualized practice. We conclude that, by thus mediating the “unmediated,” movie roadshows offer an insightful perspective on the machinery of media power in China. 相似文献
Firms pursuing technological alliances to gain competitive advantages have become a ubiquitous phenomenon in today’s business environment. This article examines which technological alliance portfolio configuration is better for focal firm performance using a portfolio rather than a dyadic perspective. To assess technological alliance portfolio effects on Korean pharmaceutical and biotechnology firms, we adopted three explanatory variables—number of alliances, number of partners, and spanning structural holes. The growth rate of revenue and the growth rate of profit are used as dependent variables. We identify two characteristics of technological alliance portfolios from the two-step generalized method of moments estimates. First, we find that between two firms with the same number of alliances, the firm with the larger number of partners would have a better performance. This result is unlike those in previous studies because it distinguishes between the number of alliances and number of partners based on the network theory. Second, we find that spanning structural holes affects firm performance rather like a double-edge sword—it positively affects the growth rate of profit but negatively affects the growth rate of revenue of firms. In short, spanning structural holes is simultaneously beneficial for firm profitability and unfavorable for firm growth. This result differs from those of earlier studies because it shows that a firm spanning structural holes among alliance partners produces either a positive or a negative effect, suggesting that a firm should vary its strategy depending on whether it prioritizes profitability or growth. 相似文献
The objective of this paper is to study the efficiency of sampling schemes suggested by Hosmer(1973), termed models Ml and M2, relative to the regular random sampling, termed model MO, when samples are drawn from a population having the Inverse Gaussian-Weibull (IG-W) mixture distribution. It has been shown that whether the efficiency is based on relative variances of the maximum likelihood estimates (ML,E's) of the components of the vector of parameters or on the generalized variances of the MLE's of that vector, Hosmer's models Ml or M2 perform better than model MO. 相似文献
It is often necessary to test whether X,…, Xn are from a certain density f(x) or not. Most test statistics such as the Kolmogorov-Smirnov, Cramer-von Mises, and Anderson-Darling statistics are based on the empirical distribution function F(x). In this paper we suggest a test statistic based on the integrated squared error of the kernel density estimator. We derive the asymptotic distribution of the statistic under the null and alternative hypothesis. Some simulation results for power comparisons are also given. 相似文献
