神话传说中的月意象探幽

在古老的神话传说中,月成为诗化的女性,是美与爱的象征,是生命与永恒的象征,是人类精神家园的象征。源于神话传说,月意象又是小农生活的现实梦幻,以及对君主专制的反叛。     

论和谐社会的法治构建

和谐社会不仅是人与人之间、人与社会之间的和谐,也是人与自然之间的和谐。社会主义和谐社会是一种各尽其能、尊重诉求、各得其所、和谐相处和共生共进的社会。法治不仅是和谐社会的重要内容,而且也是社会主义和谐社会最终实现的有力保障,我国现阶段实现构建和谐社会的战略目标应将法治作为基本的方针策略。     

Children's Conceptual Knowledge of Lying and Its Relation to Their Actual Behaviors: Implications for Court Competence Examinations

Child witnesses must undergo a competence examination in which they must show appropriate conceptual understanding of lying and truth-telling, and promise to tell the truth. Three experiments (Ns = 123, 103, 177) were conducted to address the assumptions underlying the court competence examination that (1) children who understand lying and its moral implications are less likely to lie and (2) discussing the conceptual issues concerning lying and having children promising to tell the truth promotes truth-telling. Both measures of lying and understanding of truth- and lie-telling were obtained from children between 3 and 7 years of age. Most children demonstrated appropriate conceptual knowledge of lying and truth-telling and the obligation to tell the truth, but many of the same children lied to conceal their own transgression. Promising to tell the truth significantly reduced lying. Implications for legal systems are discussed.

Y chromosome STR haplotypes of Tibetan Living Tibet Lassa

Allele frequencies and haplotypes of the 17 Y-chromosome STRs loci, namely DYS19, DYS385a/b, DYS389I, DYS389II, DYS390, DYS391, DYS392, DYS393, DYS437, DYS438, DYS439, DYS448, DYS456, DYS458, DYS635 (YGATA C4), and YGATA H4 were determined in a sample of 131 healthy unrelated males from the Lassa area of Tibet Autonomy Region of China (SW China). In 131 samples 106 different haplotypes were encountered, of which 105 were observed only once. The overall haplotype diversity was 0.9998. The results demonstrate that these loci will be very useful for human identification in forensic cases and paternity tests in the Lassa region.     

共产党员理想信念建设机制创新探赜

<正>共产党员理想信念的确立、教育不是一劳永逸的。理想信念与社会生活之间有着紧密的联系并始终处于互动之中。社会历史条件的变化,总是不断把新的问题、新的矛盾提到理想信念教育面前。如果从精神文化发展的大视域去研究理想信念建设的理论和实践,需要进一步从现实人的发展、人的需求以及人在实践中的主体地位的角度探索构建共产党员理想信念建设的新机制问题。我们这里说的"理想信念建设的机制",指的是带观律性的理想信念建设模式。     

Development of a specific fragment pattern-based quadrupole-Orbitrap mass spectrometry method to screen adulterated products of phosphodiesterase-5 inhibitors and their analogues

Recently, adulterated supplements with phosphodiesterase-5 inhibitors (PDE-5i) have frequently observed. New synthetic analogues obtained from the chemical modification of parent compounds are frequently found in illicit products despite continuous efforts to inspect for these adulterants. A rapid and accurate method based on quadrupole-Orbitrap mass spectrometry was developed for simultaneously confirming and quantifying 85 PDE-5i and derived analogues present in illicit products for erectile dysfunction (ED). Common ions of PDE-5i according to their similar structures were proposed based on MS/MS fragmentations. These common ions could be an important diagnosis of their presence targets or new emerging analogues in supplements. Several validation parameters were employed, resulting in a limit of detection and quantification of 0.09–8.55 ng/mL and 0.24–17.10 ng/mL, respectively. The linear correlation coefficient (r²) was higher than 0.995, and mean recoveries of target compounds were in the range of 82–118%. A total of 187 illicit products, obtained from on/offline markets over a period of 3 years (2015–2017), were screened by the established method. Approximately 53% of them were adulterated with PDE-5i or derived analogues at concentrations of 0.1–726.0 mg/g in the illicit products. In the interests of public health, this study describes a rapid and accurate method to determine PDE-5i and new emerging analogues in adulterated products.     

Same Routines,Different Effects: Gender,Leisure, and Young Offending

The current study seeks to extend routine activity theory by examining how gender conditions the relationship between leisure activities and adolescent delinquency. Using OLS regression with a sample of high school students from Toronto (n = 2,209), we find that (1) engaging in more unstructured and unsupervised activities with peers is associated with delinquency more strongly for boys than for girls, but is associated with substance use equally across gender; (2) this pattern is likely due to gender differences in the locations or contexts of leisure activities; and (3) prosocial leisure activities are associated with less delinquency only for boys. In general, routine activity theory appears apt at explaining the substance use of boys and girls, but is less capable of explaining the property and violent offending of girls. We discuss our findings and their implications for the growing body of research extending routine activity theory to explain gender differences in delinquency.
