Common correlates of suicidal ideation and physical assault among male and female university students in Hong Kong

This study examined prevalence and correlates of suicidal ideation and dating partner violence in a cohort of 651 university students in social sciences classes at three universities in Hong Kong. A standard questionnaire was completed within one class period to examine the rates of occurrence of physical assault perpetration and suicidal ideation. Separate rates are presented for male and female perpetrators and for severe and overall levels of violence. The differences between subjects having suicidal ideation are compared using t tests. Logistic regression is used to predict the presence or absence of physical assault in the preceding year of reporting and suicidal ideation based on the variables such as Personal Relationship Profile, age, relationship length, and socioeconomic status. Results showed that 55% of suicidal persons had a history of violence, whereas 39% of violent people had a history of suicidal ideation. Logistic regression showed that physical assault shared a total of seven associated factors with suicidal ideation. Suicidal ideation seems to have no direct relation to physical and sexual assault, but they do share some common associated factors that are essential for the development of suicide prevention.     

From Narcissistic Exploitativeness to Bullying Behavior: The Mediating Role of Approval‐of‐aggression Beliefs

This study examined the role of approval‐of‐aggression beliefs in the relationship between narcissistic exploitativeness and bullying behavior in an Asian sample (N = 809) comprising elementary children and middle school adolescents. Narcissistic exploitativeness was significantly and positively associated with both bullying behavior and approval‐of‐aggression beliefs, and approval‐of‐aggression beliefs was significantly and positively associated with bullying behavior. Additionally, findings indicated that approval‐of‐aggression beliefs was a statistically significant mediator and 53 percent of the total effect of narcissistic exploitativeness on bullying behavior was mediated by approval‐of‐aggression beliefs. Approval‐of‐aggression beliefs did not moderate the association between narcissistic exploitativeness and bullying behavior. There are important theoretical implications as well as implications for prevention and intervention efforts targeting aggressive, bullying behavior among children and adolescents.     

论群体传播时代政治传播的情感视角

在群体传播时代,情感之于政治传播,既反映群体时代政治传播的复杂性,又为认识这种复杂性提供了可能.作为政治传播主体,政府在传播态度上随传播关系的变化而发生与之相适应的改变.同时,在公众中,个人情感的不可控,使我们更加难以预知政治传播的效果.因此,在政治传播中,寻找熟悉的符号,强化信任,并将这种正面的信任固定下来,形成一种稳定的情感,是我们认识政治传播的最终目的.     

"慎刑"与"宽严相济"——以中国传统法为视角的考察

"慎刑"是中国传统法具有和谐价值的重要组成部分,能达到缓和阶级矛盾,维持政权稳定的作用。"宽严相济"是当前我国具有社会主义法制特色的刑事政策,对于化解社会矛盾、最大限度地减少不和谐因素,维护和谐稳定的社会秩序等方面有重要作用。"宽严相济"与"慎刑"存在历史的相通性,宽严相济的传统文化基础是"以人为本"和"德法兼济",而传统社会实现社会稳定、长治久安的法律手段即是"慎刑"。"慎刑"在立法层面上体现为"刑罚世轻世重",在司法层面上体现为程序上的严谨及人伦观照。"慎刑"促进了中国古代社会的稳定及政权的长治久安,对当前"宽严相济"刑事政策的立法及司法实践也具有借鉴意义。     

Efficient algorithms for finding a longest common increasing subsequence

We study the problem of finding a longest common increasing subsequence (LCIS) of multiple sequences of numbers. The LCIS problem is a fundamental issue in various application areas, including the whole genome alignment. In this paper we give an efficient algorithm to find the LCIS of two sequences in time where n is the length of each sequence andr is the number of ordered pairs of positions at which the two sequences match, ℓ is the length of the LCIS, and Sort(n) is the time to sort n numbers. For m sequences wherem ≥ 3, we find the LCIS in Sort(n)) time where r is the total number of m-tuples of positions at which the m sequences match. The previous results find the LCIS of two sequences in O(n ²) and Sort(n)) time. Our algorithm is faster when r is relatively small, e.g., for .     

Early psychosocial risk factors and postnatal parental reflective functioning

Psychosocial factors have been found to relate to parental reflective functioning (PRF), a parent's ability to mentalize about themselves and their child. Relations between maternal psychosocial risk factors and PRF were investigated in a community sample. A sample of mothers (n = 146) was assessed for risk factors when infants were 6 months, infant temperament was assessed using an observational measure, and PRF was assessed with the Parent Development Interview-Revised (PDI). PRF was measured again with the Parental Reflective Functioning Questionnaire (PRFQ) when children were 4 years (n = 105) and 5 years (n = 92), with an additional sample of mothers (n = 48) tested at these two timepoints. Results showed that in infancy, total maternal psychosocial risk related to lower PDI-PRF; regression analyses highlighted low socioeconomic status, unplanned pregnancy, and low maternal anxiety as independent predictors of lower PDI-PRF. PDI-PRF scores at 6 months did not relate to PRFQ scores, but PRFQ subscales showed stability over time from age 4–5. Results are discussed with regard to the impact of maternal psychosocial risk and infant temperament on PRF and the stability and concordance of PRF measures.     

Lifetime distributions motivated by series and parallel structures

According to Ross, any system can be represented either as a series arrangement of parallel structures or as a parallel arrangement of series structures. Motivated by this, we propose new three-parameter lifetime distributions by compounding geometric, power series, and exponential distributions. The distributions can allow for decreasing, increasing, bathtub-shaped, and upside down bathtub-shaped hazard rates. A mathematical treatment of the new distributions is provided including expressions for their density functions, Shannon and Rényi entropies, mean residual life functions, hazard rate functions, quantiles, and moments. The method of maximum likelihood is used for estimating parameters. Five of the new distributions are studied in detail. Finally, two illustrative data examples and a sensitivity analysis are presented.     

Moran's I statistic-based nonparametric test with spatio-temporal observations

Moran's I statistic [Moran, (1950), ‘Notes on Continuous Stochastic Phenomena’, Biometrika, 37, 17–23] has been widely used to evaluate spatial autocorrelation. This paper is concerned with Moran's I-induced testing procedure in residual analysis. We begin with exploring the Moran's I statistic in both its original and extended forms analytically and numerically. We demonstrate that the magnitude of the statistic in general depends not only on the underlying correlation but also on certain heterogeneity in the individual observations. One should exercise caution when interpreting the outcome on correlation by the Moran's I-induced procedure. On the other hand, the effect on the Moran's I due to heterogeneity in the observations enables a regression model checking procedure with the residuals. This novel application of Moran's I is justified by simulation and illustrated by an analysis of wildfire records from Alberta, Canada.
