The Daily Social and Emotional Worlds of Adolescents Who Are Psychologically Maltreated by Their Romantic Partners

The purpose of this study was to examine how partner psychological maltreatment is associated with depression, daily interpersonal experiences, and affect. Participants were 67 late adolescents (17- to 22-years-old). Each participant completed a survey followed by reporting affect, and interpersonal hassles and uplifts for seven consecutive days. Compared to those low in maltreatment, participants in the high maltreatment group reported more hassles with partners and friends, less uplifts with family, and more depressive symptoms. Multilevel modeling showed that adolescents in the high as compared to the low maltreatment group were more interpersonally sensitive (defined as greater affective reactions to day-to-day interpersonal hassles). Results reveal that psychological maltreatment by partners is an especially potent experience that occurs along with greater romantic hassles and more interpersonal sensitivity. The effects of maltreatment were also found to spill over into relationships with friends and families by either being associated with more hassles and greater reaction to hassles or fewer uplifts and less reaction to uplifts.

布氏锥虫伊氏亚种体外药敏试验

应用布氏锥虫伊氏亚种(Trypanosoma brucei evansi,T.b.e)体外药敏试验系统检查了国内6个T.b.e虫株和国外布氏锥虫指名亚种(T.b.b)对苏拉灭(Suramin)、贝尼尔(Berenil)、安锥赛(Antrycide)、咪唑苯脲(Imidocard)和硫胂聚氰胺(Cymelarsan)等5种抗锥虫药的敏感性。结果表明,该系统能准确测定不同虫株对各种药物的敏感性,与小鼠治疗试验结果基本相符,发现了国内抗贝尼尔和苏拉灭的T.b.e虫株。     

Columnar‐Thin‐Film‐Assisted Visualization of Depleted Sebaceous Fingermarks on Nonporous Metals and Hard Plastics

A fingermark on a nonporous substrate can be developed by depositing a columnar thin film (CTF) on it, but the CTF technique's sensitivity for low‐quality fingermarks is unknown. The optimized CTF and traditional development of several depletion series of sebaceous‐loaded fingermarks were compared using a split‐print methodology as well as subjective and objective grading schemes, in a limited laboratory trial. CTF development was superior to development with selected traditional techniques on brass, anodized aluminum, black acrylonitrile butadiene styrene (ABS), and white nylon. On white ABS and black nylon, the CTF technique performed poorly but still as well as the best‐performing traditional development technique. The CTF technique was more sensitive on brass and anodized aluminum than, and as sensitive on the four hard plastics and stainless steel as, the best‐performing traditional technique. Thus, the CTF technique is useful to develop friction‐ridge detail from limited fingermark residue on some smooth substrates.

Coping with Imprisonment: Testing the Special Sensitivity Hypothesis for White-Collar Offenders

This study uses nationally representative prison data to test two competing theories of how white-collar offenders experience prison. The first perspective, referred to as the special sensitivity hypothesis, assumes that because of their social and demographic background characteristics white-collar offenders are more susceptible to the pains of imprisonment than other inmates. The second perspective, referred to as the special resiliency hypothesis, is based on the idea that these same background characteristics may reduce the pains of imprisonment for white-collar offenders. Ordinal and binary logistic regression models are used to estimate the effect of white-collar inmate status on several indicators of psychological adjustment. The current study finds partial support for the special resiliency hypothesis, but not the special sensitivity hypothesis. The results for each outcome are discussed regarding both theoretical and practical applications. The study’s limitations are also addressed and suggestions for future research on incarcerated white-collar offenders are given.     

An Objective Measure of Splitting in Parental Alienation: The Parental Acceptance–Rejection Questionnaire

Both clinicians and forensic practitioners should distinguish parental alienation (rejection of a parent without legitimate justification) from other reasons for contact refusal. Alienated children—who were not abused—often engage in splitting and lack ambivalence with respect to the rejected parent; children who were maltreated usually perceive the abusive parent in an ambivalent manner. The purpose of this study was to assess the usefulness of the Parental Acceptance–Rejection Questionnaire (PARQ) in identifying and quantifying the degree of splitting, which may assist in diagnosing parental alienation. Results showed that severely alienated children engaged in a high level of splitting, by perceiving the preferred parent in extremely positive terms and the rejected parent in extremely negative terms. Splitting was not manifested by the children in other family groups. The PARQ may be useful for both clinicians and forensic practitioners in evaluating children of divorced parents when there is a concern about the possible diagnosis of parental alienation.     

生物检材中吗啡类生物碱的LC-MS／MS分析

目的针对滥用药物分析鉴定实践中亟待解决的问题,开展LC-MS/MS分析生物检材中吗啡类生物碱的应用研究。方法满足不同的鉴定需要,分别建立血液、尿液、唾液和头发等生物检材的样品前处理方法,确定同时分析海洛因、单乙酰吗啡、吗啡、可待因、乙酰可待因、二氢可待因酮和氢吗啡酮等吗啡类生物碱的LC-MS/MS方法。将方法应用于实际案例。结果所建立的方法对吗啡类生物碱分离良好。尿液稀释法、尿液提取法和头发中吗啡的最低检测限(LOD)分别为10ng/mL、0.01ng/mL和0.01ng/mg。结论所建立的方法简便、快速、特异性强、灵敏度高。目标物中加入二氢可待因酮和氢吗啡酮扩大了方法的实用范围。     

天津市地面沉降风险分析研究

地面沉降是城市主要地质灾害之一,天津市尤为严重。从地面沉降风险角度出发,运用AHP模糊综合评判法,对天津市地面沉降风险进行分析研究。在纵览前人研究基础上,结合自然灾害风险分析理论和天津市实际状况,建立天津市地面沉降风险评价指标体系,该指标体系由5个一级指标和18个二级指标组成。运用层次分析法确定指标相对权重,并选取5组不同权重集进行敏感度分析,以减少主观因素造成的判断误差。由于最大隶属度原则本身不足,采用加权平均法处理评判结果,得到风险综合指数,将5组风险综合指数求平均,进行最终评价。结果表明,天津市地面沉降风险水平在中等和较高之间,更偏向于较高。这与实际情况基本吻合,将该方法用于天津市地面沉降风险分析,可为防灾减灾提供科学依据。
