单用、叠用、连用——代词“如何”的语法、语义分析

“如何”在现代汉语中的使用率稍低一些。不过,它功能较多,能构成各种不同结构的句式。如“如何＋VP/AP”、“NP＋如何”、“无论/不管＋如何”、“V得＋如何”、“如何如何＋AP/VP”、“NP＋如何如何”、“VP＋如何如何”、“如何如何＋NP”等。论文从单用、叠用、连用角度归纳了“如何”的主要用法,并具体解释了它在不同语境下的具体意义。     

论网络舆情对高校群体性事件的影响

近年来,网络舆情已经成为影响高校群体性事件发生和演变的重要因素.它往往成为直接引发高校群体性事件的"导火索"、间接推动高校群体性事件恶性化发展的"催化剂"和阻碍高校群体性事件得到有效解决的"绊脚石".为了应对这些影响,应当构建高校网络舆情预警机制,加强高校网络舆情的正确引导,建立高校群体性事件的网上、网下联动应急处理机制.     

Sample size estimation for comparing rates of change in K-group repeated count outcomes

Sample size estimation for comparing the rates of change in two-arm repeated measurements has been investigated by many investigators. In contrast, the literature has paid relatively less attention to sample size estimation for studies with multi-arm repeated measurements where the design and data analysis can be more complex than two-arm trials. For continuous outcomes, Jung and Ahn (2004 Jung, S., Ahn, C. (2004). K-sample test and sample size calculation for comparing slopes in data with repeated measurements. Biometrical J. 46(5):554–564.[Crossref], [Web of Science ®] , [Google Scholar]) and Zhang and Ahn (2013 Zhang, S., Ahn, C. (2013). Sample size calculation for comparing time-averaged responses in k-group repeated measurement studies. Comput. Stat. Data Anal. 58:283–291.[Crossref], [PubMed], [Web of Science ®] , [Google Scholar]) have presented sample size formulas to compare the rates of change and time-averaged responses in multi-arm trials, using the generalized estimating equation (GEE) approach. To our knowledge, there has been no corresponding development for multi-arm trials with count outcomes. We present a sample size formula for comparing the rates of change in multi-arm repeated count outcomes using the GEE approach that accommodates various correlation structures, missing data patterns, and unbalanced designs. We conduct simulation studies to assess the performance of the proposed sample size formula under a wide range of designing configurations. Simulation results suggest that empirical type I error and power are maintained close to their nominal levels. The proposed method is illustrated using an epileptic clinical trial example.     

Arenas of comfort and conflict: peer relationship events and young people's educational attainment

Previous research suggests that developments in young people's peer relationships may either compound or alleviate the adverse impacts of other major life changes during adolescence. We explored this proposition with respect to young people's educational attainment upon leaving high school, using longitudinal data from a large cohort of Australian secondary school students (n?=?1612) who have taken part in the Our Lives research study between the ages of 12/13 and 19/20 years. Our analysis focused on the role of peer relationship events such bullying, friendship problems, falling in love, and breaking up with someone. Bullying and romantic involvement were associated with lower odds of receiving a competitive tertiary entrance rank at the end of high school. However, close, resilient friendships – in which status and identity conflicts may be more easily tolerated and resolved – may help to offset the role of these other events. As well as reviewing the consequences of our findings for young people's educational and occupational trajectories in the longer-term, we highlight their implications for future research and policy in this area.     

Life Course Status and Exchanges of Support Between Young Adults and Parents

The authors investigated intergenerational support exchanges in relation to young adults' life course status. In a sample of 2,022 young adults (ages 18–34 years) in The Netherlands, single young adults reported receiving more advice from parents than married young adults, and those with children of their own received more practical support. Married young adults and young adults with children provided less support to parents than, respectively, single young adults and young adults without children. Congruent with the life course perspective, the authors' findings suggest that the intergenerational support network is both durable and flexible, responding to the resources and needs associated with an individual's life course status.     

Comparing mean ranks for repeated measures data

Rank tests are considered that compare t treatments in repeated measures designs. A statistic is given that contains as special cases several that have been proposed for this problem, including one that corresponds to the randomized block ANOVA statistic applied to the rank transformed data. Another statistic is proposed, having a null distribution holding under more general conditions, that is the rank transform of the Hotelling statistic for repeated measures. A statistic of this type is also given for data that are ordered categorical rather than fully rankedo Unlike the Friedman statistic, the statistics discussed in this article utilize a single ranking of the entire sample. Power calculations for an underlying normal distribution indicate that the rank transformed ANOVA test can be substantially more powerful than the Friedman test.     

Resiliency in the Aftermath of Repetitious Violence in the Workplace

Summary

The definition and occurrence of traumatic events is expanding and impacts everyone's lives in some way. The degree to which a violent event impacts an individual, a group, a workplace or the community varies. Unfortunately violent events are all too common. Businesses are realizing the significance of violence as a workplace problem and the varying degrees of trauma that has a devastating impact on employee retention, workplace functionality and personal well-being. The events can include industrial or natural disasters; worksite accidents; organizational changes; suicide; homicides; robbery; assault; threats of violence and even terrorism. How prepared an organization is varies and may be correlated with how resilient individuals and the entire workplace are after workplace violence/trauma. This article focuses on what workplace violence and trauma includes, the effects of repeat events, how resilient people are while trying to prevent additional events if possible in the workplace.     

Risk-Reducing Legal Documents: Controlling Personal Health and Financial Resources

Every adult can eliminate the risk of losing control of personal health decisions and financial resources by having a last will and testament, health proxy, power of attorney, and living trust. Yet evidence suggests that less than a majority of adult Americans have these documents. We surveyed 900 adult Americans (25 plus years old) to determine what factors predict the possession of these risk-reducing documents. In total, 46% had a living will and testament, 32% a durable power of attorney, 30% a health proxy, and 18% a living trust. Events that prompt people with wealth to secure these documents, such as increasing age, getting married, having children, and experiencing a life-threatening event were the strongest predictors of having a will. These were also among the strongest predictors of having a health proxy, along with a personal history of being proactive, and a family history that fostered trust of attorneys. Affluence, age, and education were the strongest predictors of having a living trust, and the strongest correlate of having a durable power of attorney was having faced a life-threatening event, positive experiences with attorneys, and higher educational achievement.

Concretizing the Concept of Social Stress

The concept of social stress, as adapted from Selye’s work on biology, is insufficient to explain psychological functioning. To be useful, social stress must include enduring social practices characteristic of particular social systems that violate socially generated as well as biological needs. Some of these stressful events are gender role, poverty, and societal practices such as extreme competition, individualism, and materialism.
