Sex Education through a Trauma-Informed Lens: Do Parents Who See Trauma as a Problem for Youth Support Trauma-Informed Sex Education?

Trauma-informed sex education is sensitive to students’ traumatic life experiences. Internet panel data for 600 Louisiana parents/caregivers of school-age youth were used to examine parental support for trauma-informed school-based sex education, and parental characteristics associated with supporting trauma-informed sex education. Nearly three-quarters (71%) of parents agreed that youth are exposed to high levels of trauma, and 86% reported interest in school-based sex education that supports emotional wellness. Of all parental characteristics, the perception that youth are exposed to high levels of trauma was most strongly associated with endorsement of trauma-informed sex education. Louisiana parents recognize the influence of emotional wellness on youth sexual health and support trauma-informed school-based sex education, which is becoming the new standard for youth sex education services.     

Differential prospective relationships of social-oriented and individual-oriented achievement motivations with achievement goals and affective wellbeing: A 1-year follow-up study

This study aimed to investigate the differential prospective relationships of social-oriented achievement motivation (SOAM) and individual-oriented achievement motivation (IOAM) with student's adoption of specific achievement goals and their affective wellbeing (AWB). A total of 332 Chinese university students (M_age = 19.139; Female = 75%) voluntarily participated in the baseline and the 1-year follow-up surveys of this study. The factor score path analysis results showed statistically significant positive paths from SOAM and IOAM at baseline to performance goals and mastery goals, respectively, at follow-up. Moreover, a statistically significant positive path was found from SOAM at baseline to negative affective experiences, at follow-up, and no association was found between IOAM and AWB, after controlling for achievement goals. The findings suggest the usefulness of raising educators' and parents' awareness regarding the double-edged sword of utilizing socially valued motives to promote performance approach goals in individuals because such values potentially lowering their psychological wellbeing.

长期股权投资收益确认问题的探讨

长期股权投资收益的核算方法有成本法和权益法两种。在权益法下应根据投资比例和被投资企业的盈利确认投资收益，但是，这样处理不符合资产的定义和会计准则的基本要求，也是通货膨胀产生的重要原因。因此，在反映双方内在经济利益关系的基础上，有必要按收付实现制核算投资收益。
