李贺、李商隐“登仙”诗歌中的通感表现手法析论

从诗歌理论角度而言,通感是一种诗歌表现手法。唐代李贺与李商隐的"登仙"类诗歌,运用通感手法为"登仙"主题服务,可以引用通感理论来分析其具体艺术特色。另外,二李最大的不同在于是否愿意融入宗教核心。李贺宁可以艺术通感技法来"创造"一个生动活脱的仙境,也不愿深入宗教核心,这是他与义山最大的不同。而"登仙"对李贺而言是一种摹幻及创造性的审美活动,对义山而则为力图实践的宗教活动。

Parenting styles and bullying. The mediating role of parental psychological aggression and physical punishment

Studies concerning parenting styles and disciplinary practices have shown a relationship between both factors and bullying involvement in adolescence. The scarce available evidence suggests that abusive disciplinary practices increase teenagers’ vulnerability to abuse in school or the likelihood of them becoming abusers of their peers in the same context. However, there is a lack of knowledge about the indirect effect of parenting styles in adolescents’ bullying involvement through disciplinary practices, although a relationship between parenting styles and disciplinary practices has been shown. The aim of this research was to determine the mediating role of punitive parental discipline (physical punishment and psychological aggression) between the dimensions of parents’ parenting styles and their children's involvement in bullying victimization and aggression. We used a sample comprising 2060 Spanish high school students (47.9% girls; mean age = 14.34). Structural equation modeling was performed to analyze the data. The results confirmed the mediating role of parental discipline between the parenting practices analyzed and students’ aggression and victimization. Significant gender-related differences were found for aggression involvement, where boys were for the most part linked to psychological aggression disciplinary practices and girls to physical punishment. Victimization directly correlated with parental psychological aggression discipline behavior across both sexes. In conclusion, the results seem to suggest that non-democratic parenting styles favor the use of punitive discipline, which increases the risk of adolescents’ bullying involvement. Therefore, intervention programs must involve parents to make them aware about the important role they play in this process and to improve their parenting styles.

Implementing the Generalist Model in Practice

Abstract

Through a study of field tasks performed by MSW foundation students, the authors show an empirical relationship to the Gener-alist model of practice. Secondarily, the paper explores whether practice under managed care should be used to inform curriculum or whether standards embedded in curriculum should be used to influence current practice. Implications for student learning in field and classroom are discussed.

Teen Perceptions of the Promotion of Safer Sexual Practices: A Focus Group Study

Teens' own thoughts on fostering safe sexual practice are important perspectives in promoting adolescent sexual health yet are relatively absent in the literature. This focus group study explored teens' perceptions about the supports and challenges that exist as teens strive to engage in healthy sexual practices. Seventy-five teens participated in 11 focus groups using a semi-structured interview guide. School-based health centers provided the setting and facilitated sample recruitment. Focus groups were audiorecorded and transcribed verbatim. Data were analyzed using the focus group guide as a template and typologies, or clusters of concepts, were extracted to establish teen perceptions of the factors that support and challenge their ability to engage in safe sexual practices. The socio-ecological model provided the framework to identify these factors within the individual, family/parent, relational (peer/partner), community, or societal spheres of influence. Results discussed the importance of parents, the value of confidentiality, respect for teen decision-making, relationships skills, developmental aspects of the adolescent years, and social interpretations of gender. These findings revealed important considerations as adults develop policies, messages, and programs designed to promote safe sexual behavior in teens.
