大学生创业恐惧心理现状及对策

大学生对待创业的态度是积极的,但是大多数学生没有进行创业实践。创业恐惧心理已经成为阻碍大学生进行自主创业实践的重要因素。大学生创业成功率低、缺乏对自身创业能力的客观评估、缺少有效的创业支持系统和缺失宽松的创业环境等原因导致了大学生创业恐惧心理的产生。高校要以培育创新创业精神为理念,实施大学生创业教育;通过鼓励大学生参与创业计划大赛,积累实战经验。社会要以政府社会力量为依托,建立大学生创业保障体系;建立进取包容的创业文化,优化大学生创业环境。     

Self-reported mobility and instrumental activities of daily living: test-retest reliability and criterion validity

To determine the test-retest reliability and criterion validity of self-reported function in mobility and instrumental activities of daily living (IADL) in older adults, a convenience sample of 70 subjects (72.9 ± 6.6 yr, 34 male) was split into able and disabled groups based on baseline assessment and into consistently able, consistently disabled, and inconsistent based on repeat assessments over 2 weeks. The criterion validities of the self-reported measures of mobility domain and IADL-physical subdomain were assessed with concurrent baseline measures of 4 mobility performances, and that of the self-reported measure of IADL-cognitive subdomain, with the Mini-Mental State Examination. Test-retest reliability was moderate for the mobility, IADL-physical, and IADL-cognitive subdomains (κ = .51-.66). Those who reported being able at baseline also performed better on physical- and cognitive-performance tests. Those with variable performance between test occasions tended to report inconsistently on repeat measures in mobility and IADL-cognitive, suggesting fluctuations in physical and cognitive performance.     

Family structure and child outcomes: a high definition, wide angle “snapshot”

Using data from the National Survey of America??s Families (NSAF), this research investigates the relationships between a highly defined set of family structures and a broad set of child outcomes at a particular point in time in a child??s life. A detailed classification of family structures is constructed that clarifies key differences among various types of diverse families, and facilitates equivalencies testing and pairwise comparisons across nontraditional family structures. The NSAF contains a large number of observations for less common, but growing, family structures such as single-father families, grandparent-headed households and cohabiters, which makes such detailed analyses feasible and allows further stratification by child age, gender and race. The data also contains information on child behavioral, educational and physical health outcomes, as well as extensive household characteristics, economic resources and parental behaviors and inputs. Results suggest that differences across nontraditional family structures are particularly prominent for child health outcomes and that the gender of the resident parent is empirically important, more so than the presence of a cohabiting or married step-parent. Children in single father families have lesser access to health care yet enjoy better health outcomes than those in other families, even after controlling for economic resources (and inputs). In contrast, few differences are found between grandparent-headed families and other non-parent families. While we explore alternative explanations for these results, our cross-sectional data and complex set of family structure variables preclude isolating causal relationships; instead, our analyses yield empirically important distinctions that point to promising avenues for future research.

Sex differences in the development of mild cognitive impairment and probable Alzheimer’s disease as predicted by hippocampal volume or white matter hyperintensities

This study examined biological sex differences in the development of mild cognitive impairment (MCI) and probable Alzheimer’s disease (AD) development as predicted by changes in the hippocampus or white matter hyperintensities. A secondary data analysis of the National Alzheimer’s Coordinating Center Uniform Data Set was conducted. We selected samples of participants with normal cognition at baseline who progressed to MCI (n = 483) and those who progressed to probable AD (n = 211) to determine if hippocampal volume or white matter hyperintensities (WMH) at baseline predicted progression to probable AD or MCI and whether the rate of progression differed between men and women. The survival analyses indicated that changes in hippocampal volumes affected the progression to probable AD (HR = 0.535, 95% CI [0.300–0.953]) only among women. White men had an increased rate of progression to AD (HR = 4.396, CI [1.012–19.08]; HR = 4.665, 95% CI [1.072–20.29]) compared to men in other race and ethnic groups. Among women, increases in hippocampal volume ratio led to decreased rates of progressing to MCI (HR = 0.386, 95% CI [0.166–0.901]). Increased WMH among men led to faster progression to MCI (HR = 1.048. 95% CI [1.011–1.086]). Women and men who were older at baseline were more likely to progress to MCI. In addition, results from longitudinal analyses showed that women with a higher CDR global score, older age at baseline, or more disinhibition symptoms experienced higher odds of MCI development. Changes in hippocampal volumes affect the progression to or odds of probable AD (and MCI) more so among women than men, while changes in WMH affected the progression to MCI only among men.

白寿彝先生的民俗学实践与理论

白寿彝的民俗学研究表现在两个方面,一是收集整理地方文化中的民俗资料,二是进行相关的民俗现象研究。前者主要体现在对《开封歌谣集》的收集整理上,作为民国时期民俗学研究领军人物顾颉刚先生的学生,白寿彝通过编辑这部歌谣集,来反映诸多社会问题,表达对下层民众的关注,追求唤起民智的目标。后者先后体现在若干单篇论文中,其新中国成立以前论文主要是对封建迷信的歌谣观的梳理,特点是多取材于正史;其新中国成立以后论文主旨在于辨析民俗学中的传说思想,特点是取材于当代人的研究成果和充分利用传世文献,同时批评相关无学理意义的论断。这两方面的民俗学研究体现出白寿彝在民俗学理论方面的深厚修养,以及民俗学与历史学密切结合、关注下层民众、适应时代发展需要的高度自觉,至今具有一定的示范和借鉴价值。
