High performance liquid chromatographic determination of alcohols with reference to body distribution of methanol

A method has been developed on reverse phase high performance liquid chromatography for simultaneous determination of methyl, ethyl and isopropyl alcohols under refractive index detection using pure water as the mobile phase. A good separation has been achieved between these alcohols. Detector response was linear with a detection limit of 5 mg/100 ml. Recovery studies were performed by adding known amounts of methyl and ethyl alcohols to blood, lung and liver within the range 80–90%. The reproducibility of the results was always >90%. The quantitative distribution of methyl alcohol in postmortem body tissues and fluids has been reported in three cases of poisoning.

Beliefs About Wife Beating Among Arab Men from Israel: The Influence of Their Patriarchal Ideology

Despite the recent increase in public and professional interest in the problem of wife beating in Arab society, in Israel, and in the rest of the Arab world, there is a serious lack of empirical research on different dimensions of the problem in those societies. This paper presents the results of a survey conducted among a systematic random sample of 362 Arab husbands from Israel, in an attempt to examine the contribution of patriarchal ideology toward explaining their beliefs about wife beating. Although about 58% of the participants indicated that there is no excuse for a man to beat his wife, 15–62% still justified wife beating on certain occasions (e.g., adultery, failure to obey husbands, disrespect for parents and relatives). In addition, although the participants tended to perceive abusive and violent husbands as responsible for their behavior, 52% still expressed understanding of that behavior and, on some occasions, 23–43% even blamed the wife for violence against her. Regression and multiple regression analyses revealed that over and above the participants' age and level of education, their masculine sex-role stereotypes, negative and traditional attitudes toward women, nonegalitarian marital role expectations, and familial patriarchal beliefs were the most significant predictors of beliefs about wife beating. Implications of the results and limitations of the study are also discussed.     

博观约取 厚积薄发——漫谈毕业论文的写作

<正> 按照规定,大学本科学生和研究生,包括博士研究生,毕业前都必须写作毕业论文.毕业论文究竟应当怎么写呢?常有同学向我提出这个问题.这使我想起了鲁迅先生写的一篇题为《作文秘诀》的文章.但这篇文章并不是真正告诉人们以什么作文的"秘诀",而恰恰是指出作文并没有什么"秘诀";所谓"秘诀",无非是写作时装腔作势,故弄玄虚,用某种障眼法吓唬人、愚弄人罢了.那么,作文就没有什么要注意的么?当然也有.用鲁迅的话说,那就是"有真意,去粉饰,少做作,勿卖弄".我想这道理同样适用于写作毕业论文.

Anthropological analyses of 30 insertion/deletion autosomal markers in five major ethnic groups of Pakistan

We investigated the forensic efficacy of the 30 insertion/deletion (Indel) markers included in the Qiagen Investigator® DIPplex kit in 529 Pakistani individuals from five major subpopulations in Pakistan (Punjabi, Pashtun, Sindhi, Saraiki, and Baloch). In the Sindhi population, the distribution of HLD81 and HLD97 alleles deviated from Hardy-Weinberg equilibrium after Bonferroni correction. The combined match probability ranged from 2.0E-12 (Pashtun and Baloch) to 1.0E-12 (Sindhi), and the mean paternity exclusion power varied from 0.995 (Punjabi, Sindhi, and Saraiki) to 0.996 (Pashtun and Baloch). The high combined power of discrimination (0.999 999 999 999 97) and low combined match probability (1.7E-12) for all subpopulations studied support the utility of the 30 Indel markers for forensic identification in the studied subpopulations. The allele frequencies of the Indel markers in the Pakistani subpopulations were compared with those from 18 other populations. The results show that the populations clustered according to geography. The subpopulations investigated in this work showed a close genetic relationship with others from Pakistan, as well as with South Central Asian and Middle Eastern populations. The results suggest that the Investigator^® DIPplex kit can be useful as a supplementary tool for human identification in the five Pakistani subpopulations investigated in this study.Supplemental data for this article is available online at https://doi.org/10.1080/20961790.2021.1933366 .     

Job Expectations and Career Goals of Title IV-E Child Welfare Social Workers with Varying Levels of Work Experience: How Do They Differ?

A comparison of three groups of Title IV-E child welfare workers revealed significant differences among all groups on job expectations and career goals. New workers reported most positive expectations for their jobs, and greatest interest in child welfare careers and in pursuing educational goals. Seasoned workers expressed least positive expectations and least interest in future child welfare careers and educational goals. Findings may assist universities in student selection and curriculum. Child welfare agencies may benefit in areas of recruitment, training, and policies. Realistic job previews might moderate high expectations for new workers and reduce unmet expectations for experienced workers.     

Getting Ratees to Accept Performance Feedback: A Relational Approach

This paper seeks to understand the association between ratees’ relational justice perceptions and their feedback acceptance, both directly and through leader–member exchange (LMX). The paper also examines the moderated mediation effect of supervisory trust. The paper presents the findings of two studies. Study 1 utilized two data sets collected through an online survey from 280 part-time students working full-time (Sample 1) and 292 working professionals (Sample 2) in Pakistan. Study 2 utilized data collected from N?=?167 students recruited for a scenario-based experiment that manipulated whether a manager was fair or unfair. Results revealed that relational justice positively predicted feedback acceptance in Studies 1 and 2. LMX positively mediated the above-mentioned relationship in both studies. As expected, supervisory trust negatively moderated the relational justice–feedback acceptance relationship in Study 2. The present study contributes to performance management theory and practice by illuminating that raters can stimulate performance partnership by employing a relational justice approach that increases the likelihood that employees accept performance feedback.

     

Preventing radicalism in educational institutions: Pakistan a case in point

With the recent drastic shifts in societies, thinking styles, and most importantly, the degree of online‐and‐offline exposure, it is easy for the young and developing mind to fall prey to radical or extremist ideas. Radical organizations direct their recruiting efforts toward those who have yet to reach adolescence and are incapable of forming well‐informed and educated decisions. Since it is in human nature to target the weak and the vulnerable, these organizations look for dissatisfied, isolated and friendless young people. They are especially allured when these organizations promise to get them all they lack. As there have been incidents recently reported on young students' involvement in terror activities, the study proposes alternatives to prevent them from falling prey to radical thoughts. The proposed alternatives are judged through TOPSIS (Technique of Order Preference Similarity to the Ideal Solution) and the ideal alternative is singled out after mathematical calculation. Out of the five proposed alternatives, the study, through TOPSIS analysis, proposes that parents may be trained to handle their children in order to keep them from radical thoughts. In addition to the ideal alternative, the study also suggests that the government take preventive measures to curb the evil of radicalism.
