城市父母对青少年子女性教育知识和态度的调查

本文通过对北京、上海和西安三个城市的841位有青少年子女的父母的问卷调查,了解他们的性知识水平和对性及对青少年性教育的态度。调查发现,大多数父母具备一定的性生殖、艾滋病和性保健及性行为等方面的知识;对性持较为开放的观念;对在家庭和学校开展对青少年的性教育持肯定态度。调查还发现,父母的教育程度越高,性知识水平越高;父母性知识水平越高,对性及对青少年性教育的态度也越积极。     

The Effects of E-Government on Trust and Confidence in Government

Trust in government has been declining for more than three decades now. E-government has been proposed as a way to increase citizen trust in government and improve citizen evaluations of government generally. Using two-stage models to analyze recent Pew survey data, this research explores the relationship between e-government use, attitudes about e-government, and trust in government. There is a statistically significant relationship between trust and use of a local government Web site, as well as other positive assessments of federal and local governments. The evidence suggests that e-government can increase process-based trust by improving interactions with citizens and perceptions of responsiveness. The findings are theoretically important for reconciling the conflicting research on the effects of e-government and for understanding variations by level of government. Citizen attitudes toward government, including trust, are core concerns for democratic governance and public administration.     

Do Parenting Behaviors Predict Externalizing Behavior in Adolescence, or Is Attachment the Neglected 3rd Factor?

The aim of this study was to examine the role of attachment in the link between parenting behaviors (including positive parenting and negative control) and problem behaviors during adolescence. Using questionnaires, we examined 511 Flemish, Dutch-speaking adolescents ranging in age from 10 to 18 years. We distinguished 3 age groups (10–12, 13–15, and 16–18 years) and conducted mediation and moderator analyses, using multiple regression analyses. Results showed that attachment towards mother and father mediates between negative control and problem behavior in the 1st 2 age groups. The strength of the link between parenting and problem behavior was less strong in the older age groups, while the strength of the link between attachment and parenting was equally important across age groups. Only in the youngest age group, we found some evidence for a parenting by paternal attachment interaction. These findings suggest the need for tailoring existing preventive parent management trainings: more attention should be paid to improve the quality of parent–child interactions and the forthcoming attachment bonds.

Judicial Performance and the Rule of Law in the Mexican States

What determines how judicial institutions perform? Prominent theoretical approaches, such as international political economy, institutional rational choice, social capital, and structural theories, suggest that international economic actors, political competition, political participation, and poverty may all be important forces driving institutional behavior. This study analyzes these various theoretical approaches and uses qualitative and statistical analysis to compare judicial performance in the Mexican states. It provides evidence to support the institutional rational choice hypothesis that political competition generates judicial independence. Poverty, political participation, and an export‐oriented economy seem to influence judicial access and effectiveness.     

Studies document gender differences in HIV risk and impact

According to new studies, women account for half the new HIV infections in Aboriginal people, and women who inject drugs are at higher risk than their male counterparts.     

The propensity of individuals to deposit DNA and secondary transfer of low level DNA from individuals to inert surfaces

We have shown that there is a difference between individuals in their tendency to deposit DNA on an item when it is touched. While a good DNA shedder may leave behind a full DNA profile immediately after hand washing, poor DNA shedders may only do so when their hands have not been washed for a period of 6h. We have also demonstrated that transfer of DNA from one individual (A) to another (B) and subsequently to an object is possible under specific laboratory conditions using the AMPFISTR SGM Plus multiplex at both 28 and 34 PCR cycles. This is a form of secondary transfer. If a 30 min or 1h delay was introduced before contact of individual B with the object then at 34 cycles a mixture of profiles from both individuals was recovered. We have also determined that the quantity and quality of DNA profiles recovered is dependent upon the particular individuals involved in the transfer process. The findings reported here are preliminary and further investigations are underway in order to further add to understanding of the issues of DNA transfer and persistence.
