Nail analysis for the assessment of caffeine abuse in Northwest China: A population-based study

Caffeine is the most widely consumed psychoactive agent worldwide and has the potential for abuse, but studies monitoring caffeine abuse in China are scarce. This study aims to estimate the prevalence of caffeine abuse in northwest China and investigate the correlation between caffeine and other drugs in hair and nails using an ultra-performance liquid chromatography-tandem mass spectrometry (UPLC-MS/MS). Fingernail clippings were collected from 376 participants in northwest China to detect caffeine and 13 other illicit psychoactive drugs and their metabolites. Paired hair and nail samples were collected from 39 participants to investigate the correlation between caffeine and other drugs in hair and nails. The samples were decontaminated, pulverized, and extracted by a high-throughput nail sample preparation method and analyzed by UPLC-MS/MS. The results showed a risk of caffeine abuse in northwest China, with concentrations ranging from 0.43 to 10.6 ng/mg for healthy volunteers, 0.49–246 ng/mg for caffeine abusers, and 0.25–363 ng/mg for drug addicts in community rehabilitation centers. Caffeine was detected together with other illicit psychoactive drugs and their metabolites. Furthermore, positive detection correlations were found between hair and nail samples. This study provides a current perspective on caffeine abuse in northwest China and demonstrates the practical use of UPLC-MS/MS for the simultaneous detection of caffeine and 13 illicit psychoactive drugs and their metabolites in hair and nails. The results highlight the potential of nails as a supplementary matrix when hair samples are unavailable and emphasize the need for handling caffeine carefully given its potential for abuse.     

Work Conflict as Predictor of Job Stress＂ The Case of an Italian Public Administration

Job stress is a pervasive problem for workers and employers in today＇s economy and it is a timely and important topic for organizational setting. Negative job stress may adversely affect an employee＇s mental and physical health. The aim of the present research is to explain why job stress in the public administrations is a theme of increasing interest and why many studies have analyzed its functioning and diffusion. The variables influencing job stress are numerous and often analyzed from different perspectives. Despite the influence of a number of different factors, job stress can be studied by looking at several aspects as physical environment or/and psychosocial environment. This preliminary study investigated the role of one psychosocial source, level of perceived work conflict, on job stress. A case study was presented. A survey instrument was used to collect information from a Regional Public Administration of South Italy. Data from 1,127 respondents, representing a 91.63% of response rate, were analyzed. Statistical correlations and hierarchical regression showed that work conflict was a predictive aspect of job stress and has the highest contribution to explain the phenomena. The present research has a multidisciplinary value, by linking business science, psychology, and social science.     

On Active Citizenship: Discourses and Language about Youth and Migrants in Italy

Abstract

The civic and political participation of young people and especially young migrants, who have limited rights of citizenship, is still a significant problem in Italy. Young people struggle to find opportunities and feel excluded from politics: the political agenda tends to see them more as a problem than as a resource. In this article, we illustrate the results of research to understand the dynamics of political and civic participation of young people and what the policy does in their favour. A content analysis of a corpus of European and Italian legislation, policy and planning documents has been undertaken. We also conducted six in-depth interviews with politicians and representatives of Italian nongovernmental organizations in order to investigate (a) policy priorities and institutional points of view, (b) consistency between these priorities and European programmes, and (c) European Union support for the policy actions and projects promoted in Italy about youth. The results showed a general difficulty for young people to ‘engage’ and be engaged in civic and political activities. There is also a gap between the political level and an effective investment which will recognize young people as a real resource.     

单管一步甲基化可变位点分析技术

目的建立单管一步甲基化可变位点（methylationvariableposition,MVP）分析技术一单管消化后PCR链融解曲线分析（post—digestionPCR—meltingcurveanalysis,PDP—MCA）。方法以文献报道的差异甲基化区（differentiallymethylatedregion,DMR）为模型,在MVP两侧设计一组解链温度各不相同的引物。应用FastDigest甲基化敏感性限制酶（methylation—sensitiverestrictionenzyme,MSRE）,在同一反应管内顺次进行DNA的酶切、复合扩增和MCA检测．生成MCA图谱。同时用该方法和传统的MSRE—PCRMCA技术检测相同样品（外周静脉血、精液、阴道液各5份）,比较两种方法检测结果,验证其可行性,并分析比较不同样品的MCA／HRM图谱。结果解链温度相差2℃以上的片段,MCA峰分离良好,复合扩增后可以用MCA技术检测。应用单管PDP—MCA技术,可以集酶切、扩增和检测三步于一管,在2h内得到与传统方法一致的特异性图谱和数据,并实现样品的快速分类鉴别。结论单管PDP-MCA技术可以实现多个MVP的单管、闭管检测,具有简便、快速、易于自动化等优点,可用于样品DNA甲基化差异的检测。     

A brief measure of the triarchic model of psychopathy among community youths: psychometrics and measurement invariance

ABSTRACT

The development and validation of empirically sound measures that operationalize the Triarchic model of psychopathy among youth is currently in the nascent stage. The present study aimed to examine the psychometric properties of a brief refined measure of the Triarchic model of psychopathy based on the Youth Psychopathic Traits Inventory (YPI-Tri-S) among a mixed-gender school sample of 782 youth (M?=?15.87 years, SD?=?1.72) from Portugal. Confirmatory factor analysis offered support for the theoretically expected three-factor structure. Cross-gender measurement invariance using the present sample and cross-sample measurement invariance of the YPI-Tri-S using a previously collected forensic sample of institutionalized males was established. The YPI-Tri-S showed adequate psychometric properties in terms of discriminant validity, convergent validity, concurrent criterion-related validity, known-groups validity, and internal consistency. Findings indicate that YPI-Tri-S is a valuable brief and psychometrically reliable and valid self-report measure of the Triarchic model of psychopathy for use in diverse samples of youth.

Emerging cohort trends in housing debt and home equity

Abstract

Financial and market conditions in the 1990s caused a sharp increase in the housing debt (in constant dollars) of households now approaching or just past normal retirement age. Households now in middle age have also set new records for housing debt and will likely continue to carry high housing debt when they reach old age in 10 or 20 years.

In the future, this housing debt burden is likely to lead to financial and housing adjustments that suggest a qualitative change in behavior when these households reach the later stages of their working life. Many will need to work longer to service housing debt. When facing a life‐cycle downturn in annual income, households will be increasingly motivated to tap into their home equity, both by borrowing, for those who stay in their homes, or by downsizing and liquidating some equity, for those who choose to move.
