后方法理论视角下“成果法”与“写长法”教学模式对比研究

基于后方法理论的指导,就“成果法”和“写长法”这两种不同的教学模式对不同写作水平的大学英语学习者所产生的影响进行了对比实验研究.研究发现,尽管教学方法本身并无孰优孰劣之分,“成果法”与“写长法”都能一定程度上提高不同写作水平受试者的成绩,但是“写长法”对于不同写作水平受试者的效果显著优于“成果法”.     

Planned Happenstance Skills and Occupational Identity Status in High School Students

This study investigated how the 5 components of planned happenstance skills are related to adolescents' occupational identity statuses. A canonical correlation analysis was performed with a sample of 370 high school students in South Korea. The results indicated that higher identity statuses (i.e., achievement and moratorium statuses) were significantly related to the 5 components of planned happenstance skills, whereas lower identity statuses (i.e., foreclosure and diffusion statuses) were not significantly related to the 5 components of planned happenstance skills. In addition, the results of the mediation analysis indicated that the transition from moratorium to achievement status was positively mediated by 3 components of planned happenstance skills: optimism, persistence, and risk taking.     

伊朗和美国关系中的伊斯兰因素解析

储层伤害试井评价新方法研究

针对传统储层伤害试井评价的污染带渗透率求取存在较大偏差，进而影响表皮系数准确分解的问题，建立了改进的麦金利图版试井分析新模型，利用拉普拉斯变换进行了求解，并编程绘制了新的分析理论图版（改进的麦金利图版），获得了新的拟合解释方法，可以非常准确地求取污染带渗透率。再利用Hawkins 公式，优化计算真表皮系数和污染半径，从而利用污染带渗透率、污染半径和真表皮系数进行储层伤害试井评价。最后，进行了实例分析，结果符合现场实际，为改善储层、采取措施提供了依据。     

辛亥革命研究的整体性问题

辛亥革命爆发迄今已整整百年。这场举世瞩目的革命虽然离我们已愈来愈遥远,但其重要意义与历史地位却并未因此而被忽略。百年以来,辛亥革命对中国近现代历史进程的重要意义,乃至在亚洲及世界范围内所产生的重大影响,一直受到广泛的关注。海内外学界对辛亥革命的研究也可谓硕果累累。在百年纪念到来之际,需要我们思考的是:辛亥革命史研究如何更加走向深入,怎样更进一步挖掘辛亥革命的历史价值与现实意义?为此,也需要学者们以百年之眼光对辛亥革命重新加以审视,从而实现辛亥革命史研究的百年超越。这一组笔谈,分别从不同的角度对如何扩展与深化辛亥革命史研究,提出了一系列新的认识与学术见解,多有启迪意义,对于促进辛亥革命史研究向纵深发展将会起到积极的作用。     

Urgent engagement in 9/11 pregnant widows and their infants: Transmission of trauma

The potential effects of maternal trauma on mother–infant interaction remain insufficiently studied empirically. This study examined the effects of the September 11, 2001, trauma on mother–infant interaction in mothers who were pregnant and widowed on 9/11, and their infants aged 4–6 months. Split‐screen videotaped interaction was coded on a one‐second basis for infant gaze, facial affect, and vocal affect; and mother gaze, facial affect, and touch. We examined the temporal dynamics of communication: self‐contingency and interactive contingency of behavior by time‐series methods. We documented heightened maternal and infant efforts at engagement in the 9/11 (vs. control) dyads. Both partners had difficulty tolerating moments of looking away as well as moments of negative behavior patterns. Heightened efforts to maintain a positive visual engagement may be adaptive and a potential source of resilience, but these patterns may also carry risk: working too hard to make it work. A vigilant, hyper‐contingent, high‐arousal engagement was the central mode of the interpersonal transmission of the trauma to these infants, with implications for intervention.     

The Planned Happenstance Career Inventory: A Cross‐Cultural Comparison

This study examined the measurement invariance and latent mean difference of an English version (J. H. Lee et al., 2017) of the Planned Happenstance Career Inventory (PHCI; B. Kim, Jung, et al., 2014) across cultures. Participants were 262 American and 291 South Korean undergraduates. Measurement invariance results indicated that the 5‐factor structure was adequate for both groups and that conditions for configural, metric, and partial intercept invariance were met. Latent mean analysis was used to compare the mean scores of the PHCI skills (curiosity, flexibility, persistence, optimism, and risk taking). The latent means of curiosity, flexibility, persistence, and optimism were higher among South Korean undergraduates, but no significant difference was found regarding risk taking. Career counselors should consider differences in planned happenstance perceptions across cultures to provide better career guidance. Future studies are needed to verify the distinctive nature of flexibility by replicating the factor structure of the PHCI with other samples.     

Examining the variation in local water sustainability practices

As sustainable development is becoming more important to ensure the economic success and social well-being of any government, without regard to its level, the efficient use and protection of natural resources has increased in importance. And local governments are at the forefront of developing sustainability policy in many ways. This study investigates the factors that influence the variation in local sustainability practices in one critical area, water conservation. The variation in adoption of water sustainability programs in municipalities across the U.S. is hypothesized to rely on three key factors: environmental condition, form of government, and fiscal condition. Our findings from an ordered logistic regression model indicate that municipalities with high drought level, high environmental policy priorities, and high community wealth are likely to adopt more water conservation programs.     

Toward a Composite Measure of Green Consumption: An Exploratory Study Using a Korean Sample

This study developed a composite measure of green consumption behaviors, incorporating multiple dimensions of green consumption behaviors. As a result of an extensive literature review, four value orientations were proposed: health-related egoistic value orientation, resource-related egoistic value orientation, altruistic value orientation, and biospheric value orientation. And a composite measure of green consumption which measured green consumption behavior manifesting the suggested value orientations were proposed and empirically tested using a Korean sample. After empirical testing and validating the proposed composite measure according to the measurement validation procedure proposed by Nunnally (New York: McGraw-Hill Book Company, 1978), the composite measure of green consumption behaviors was revised to three dimensions of green consumption behaviors: health-conscious green consumption behavior, resource-conscious green consumption behavior, and socially conscious green consumption behavior that combined originally suggested altruistic and biospheric value orientations. A multivariate regression analysis was employed to test the usability of the composite measure of green consumption behaviors and to identify the determinants of green consumption behaviors. As hypothesized, the results of regression analysis showed that perceived consumer effectiveness, reference persons, and perceived market situation are significant determinants of green consumption behaviors, and the effects of environmental concern and socioeconomics are limited. Based on these findings, public policy and marketing implications that promote green consumption are also proposed.     

A Moderated Mediation Model of Planned Happenstance Skills,Career Engagement,Career Decision Self‐Efficacy,and Career Decision Certainty

This study examined how college students’ levels of planned happenstance skills influenced the relationships among career engagement, career decision self‐efficacy, and career decision certainty. Moderated mediation analysis was used with a sample of 217 Korean undergraduate students. The results indicated that career decision self‐efficacy mediated the relationship between career engagement and career decision certainty. Moreover, the positive indirect effect of career engagement on career decision through career decision self‐efficacy was strengthened as the level of planned happenstance skills increased. In conclusion, college students’ career engagement strengthens their career decision certainty via career decision self‐efficacy when they have enough planned happenstance skills to discover unexpected career opportunities.
