Infusion of lidocaine into the dorsal hippocampus before or after the shock training phase impaired conditioned freezing in a two-phase training task of contextual fear conditioning

Learning in a contextual fear conditioning task involves forming a context representation and associating it with a shock. The dorsal hippocampus (DH) is implicated in representing the context, but whether it also has a role in associating the context and shock is unclear. To address this issue, male Wistar rats were trained on the task by a two-phase training paradigm, in which rats learned the context representation on day 1 and then reactivated it to associate with the shock on day 2; conditioned freezing was tested on day 3. Lidocaine was infused into the DH at various times in each of the two training sessions. Results showed that intra-DH infusion of lidocaine shortly before or after the context training session on day 1 impaired conditioned freezing, attesting to the DH involvement in context representation. Intra-DH infusion of lidocaine shortly before or after the shock training session on day 2 also impaired conditioned freezing. This deficit was reproduced by infusing lidocaine or APV (alpha-amino-5-phosphonovaleric acid) into the DH after activation of the context memory but before shock administration. The deficit was not due to drug-induced state-dependency, decreased shock sensitivity or reconsolidation failure of the contextual memory. These results suggest that in contextual fear conditioning integrity of the DH is required for memory processing of not only context representation but also context-shock association.

A Study of Suicide and Socioeconomic Factors

The topic of suicide has long been an important socioeconomic issue studied in many countries. Suicides inject an atmosphere of unrest into society, and media attention furthers that social uneasiness. From the viewpoint of economics and management, suicide is a waste of human resource: it decreases the labor force in society and deteriorates human capital. This paper provides a series of analyses of suicide rate based on theoretical reasoning and empirical approaches. Aggregate data from G7 countries are obtained and stacked into panel data for analysis. Data are collected for different age groups. Even though suicide issues have been extensively discussed in the past, newly developed econometric tools are applied to her. Beyond previously recognized relationships between economic factors and suicide rates findings include that unemployment strikes men more than women in terms of psychological pressure: for middle age or older women, unemployment may even be positive for the entire family; and female labor force participation exerts pressure on male counterparts and increases its suicide rate. As a result, a low income family with an unemployed man and an employed woman is at high risk for adult male suicide.     

Correlates of victimization in Chinese children's peer groups.

This study reports a cross-sectional investigation of the behavioral and academic correlates of victimization in Chinese children's peer groups. The participants were 296 children (161 boys and 135 girls; mean age = 11.5 years) from Tianjin, China. Multi-informant assessments (peer nominations, teacher ratings, and self-reports) of peer victimization, aggression, submissiveness-withdrawal, assertiveness-prosociability, and academic functioning were obtained. Structural equation models indicated that peer victimization was associated with poor academic functioning, submissive-withdrawn behavior, aggression, and low levels of assertive-prosocial behavior. These findings suggest that there is considerable similarity in the social processes underlying peer group victimization across Chinese and Western cultural settings.     

Preventing Teen Relationship Abuse and Sexual Assault through Bystander Training: Intervention Outcomes for School Personnel

The purpose of the current study was to examine the impact of exposure to Bringing in the Bystander—High School Curriculum (BITB-HSC) on school personnel, which included a seven session classroom curriculum for ninth through twelfth graders (student curriculum), a bystander training workshop for school personnel (school personnel workshop), and reading materials (handout). We examined how exposure to these various BITB-HSC intervention components was associated with school personnel's knowledge and bystander efficacy, intentions, and barriers specific to student relationship abuse (RA) and sexual assault (SA). Participants were 488 school personnel from 12 high schools in upper New England who completed the 4-month follow-up survey that assessed for intervention exposure (284 participants completed both the baseline and follow-up survey). Whereas 53% of participants were exposed to no intervention components, the other half of the sample were exposed to a combination of intervention components. Higher baseline knowledge and reactive bystander intentions were associated with subsequent exposure to both the student curriculum and the handout, and fewer barriers to bystander action predicted exposure to the school personnel workshop. Exposure to the school personnel workshop, student curriculum, and handout was associated with subsequent greater knowledge, exposure to the student curriculum predicted reactive bystander intentions, and exposure to the handout predicted higher reactive bystander intentions and bystander efficacy. Findings suggest that despite challenges with engagement, exposure to the BITB-HSC components may be a useful tool in improving school personnel's responses to RA and SA among high school students.
