Natural Mentoring Relationships as a Protective Factor for Victims of Bullying

School bullying is associated with a host of unfavorable psychosocial outcomes, even as victims enter college. Thus, the identification of modifiable protective factors remains an important goal of psychological research in the context of resilience theory. The purpose of this study was to examine the moderating effect of natural mentoring relationships (NMRs) on the association between peer victimization and college adjustment. Participants were 239 undergraduate students from a rural Midwestern university. Results indicated that higher levels of past peer victimization were associated with higher levels of depression and interpersonal problems. The presence of NMRs moderated the relationship between past peer victimization and interpersonal problems. Though further study is necessary, NMRs among school-aged students who experience bullying may be beneficial.     

Simultaneous Determination of 13 Anticoagulant Rodenticidesin Human Blood by Liquid Chromatography–Tandem Mass Spectrometry and its Application in Three Poisoning Cases

Anticoagulant rodenticides are widely used for rodent control around the world. A rapid and sensitive method was developed and validated for the simultaneous determination of 13 anticoagulant rodenticides (coumafuryl, pindone, valone, warfarin, coumatetralyl, coumachlor, diphacinone, dicumarol, chlorophacinone, bromadiolone, difenacoum, flocoumafen, and brodifacoum) in human blood by liquid chromatography–tandem mass spectrometry. After liquid–liquid extraction, the anticoagulant rodenticides were separated on an Eclipse Plus C18 column. Linearities were observed for each analyte in blood ranging from 0.5 to 50 ng/mL, with correlation coefficients over 0.99. The limits of detection ranged from 0.01 to 0.2 ng/mL, and the limits of quantification were 0.5 ng/mL for all analytes. The intraday and interday precisions were <15%, and accuracies ranged from 80.3% to 111.0%. This validated method with high sensitivity has been applied in three anticoagulant rodenticide poisoning cases and has been used successfully in monitoring blood concentrations for months.     

Intellectual property law and practice in the blockchain realm

Blockchain technology is claimed to be and perceived as one of the revolutionary technologies that will have an enormous impact on our lives in the forthcoming years and decades. The legal questions surrounding blockchain appear to be among the most controversial issues surrounding this novel technology, which create uncertainties as to the scope and speed of its eventual adoption. Is it legal to use blockchain technology? Does or should any governmental authority or court take a record stored in blockchain into consideration in their decisions? Is blockchain reliable? Can the technology be used for the protection and enforcement of legal and property rights?The technological advancements offered by blockchain promise wide ranges of use in a variety of sectors and legal areas, including intellectual property (IP) law. This paper will focus primarily on the possible opportunities that blockchain may offer with respect to the future of IP law and discuss its potential impact on the registration, management and enforcement of intellectual property rights. We will proceed to offer blockchain-based solutions to foster the operation of IP offices, reinforce customs procedures in detecting counterfeit products, and enhance the efficiency of IP rights management by the right holders. The paper concludes by providing some suggestions to pave the way for the advancement of blockchain technology and to increase the number of people that this technology reaches, as well as its successful integration into the various services and registration/transaction channels that we use today.     

LYNCHINGS,RACIAL THREAT,AND WHITES’ PUNITIVE VIEWS TOWARD BLACKS

Disparities in historical and contemporary punishment of Blacks have been well documented. Racial threat has been proffered as a theoretical explanation for this phenomenon. In an effort to understand the factors that influence punishment and racial divides in America, we draw on racial threat theory and prior scholarship to test three hypotheses. First, Black punitive sentiment among Whites will be greater among those who reside in areas where lynching was more common. Second, heightened Black punitive sentiment among Whites in areas with more pronounced legacies of lynching will be partially mediated by Whites’ perceptions of Blacks’ criminality and of Black‐on‐White violence in these areas. Third, the impact of lynching on Black punitive sentiment will be amplified by Whites’ perceptions of Blacks as criminals and as threatening more generally. We find partial support for these hypotheses. The results indicate that lynchings are associated with punitive sentiment toward Black offenders, and these relationships are partially mediated by perceptions of Blacks as criminals and as threats to Whites. In addition, the effects of lynchings on Black punitiveness are amplified among White respondents who view Blacks as a threat to Whites. These results highlight the salience of historical context for understanding contemporary views about punishment.     

美国的极地资源开发政策考察

在后《南极条约》时代,美国持续关注悬而未决的南极资源问题,强调在不破坏南极环境的情况下,自由开发南极资源的可能性。20世纪80年代,美国国内曾就是否设立南极资源开发制度发生激烈的争论。目前,南极的资源开发问题虽被冻结,但美国依然担心这一问题在未来仍将威胁南极条约体系的稳定性。同样,美国也通过了多个涉及北极主权和资源开发问题的政策和法律文件,并为资源开发做技术准备,以防在北极利益竞争中落后。但总的来看,美国越来越意识到开发极地资源与保护环境之间的矛盾,认为需防止因争夺资源而出现严重的国际争端。

Prevalence and demographic correlates of intimate partner violence in Asian Americans

This study provides the first national estimates of the prevalence and correlates of intimate partner violence (IPV) among Asian Americans. Population estimates are based on data from 1470 Asian Americans interviewed for the National Latino and Asian American Study. Interviews were conducted in English, Chinese, Tagalog, or Vietnamese. Results suggest that rates of IPV among Asian Americans are low compared to the general U.S. population. Minor violence victimization by a current intimate partner was reported by 10.2% of women and 12.0% of Asian American men. Notably, a greater proportion of participants admitted having perpetrated IPV than having been a victim. Predictors of IPV included younger age, higher SES, alcohol- and substance-use disorders, depression, ethnicity, and being U.S.-born. Results suggest the need for additional research to examine the interactions between gender, ethnicity, and acculturation to develop group-specific models of IPV risk and resilience within diverse Asian American groups.     

Self-esteem of young adults experiencing interparental violence and child physical maltreatment: parental and peer relationships as mediators

This study examined the joint impact of experiencing both interparental violence and child physical maltreatment on young adults' self-esteem. It also tested the hypothesis of parental and peer relationship qualities as mediators in the relationship between childhood histories of family violence and adult self-esteem. Data were collected from a national probability sample of 1,924 college students in Taiwan. Research results demonstrated that experiencing both interparental violence and physical maltreatment during childhood have long-term and detrimental impact on adult self-esteem. This impact was statistically independent of other potential confounding factors. Moreover, participants experiencing dual violence during childhood reported lower self-esteem than those experiencing only one type of family violence or none at all. Male participants who experienced dual violence reported lower self-esteem than female participants who experienced dual violence. Further analyses revealed that parental and peer relationship qualities mediated the joint impact of interparental violence and physical maltreatment on adult self-esteem.
