人民币升值的正负效应及抵消对策分析

人民币升值对中国经济的影响具有正负双重效应。笔者从微观和宏观、内部经济和外部经济的角度,分析现阶段人民币升值对我国经济所产生的正负效应,提出以人民币升值的正效应抵消其负效应的对策,使人民币升值对我国经济建设的负面影响降到最低,直至实现宏观上的正效应大于负效应的目标。     

钢琴基础教育双向性的探析

随着素质教育的全面推进,钢琴也越来越得到了人们的喜爱,开始由象牙塔进入寻常人家。但钢琴教育过快过热的发展,也带来了些负面因素,不经意间令钢琴的教学忽略了基础教育,本来需要扎实学习才能出效果的钢琴技能学习变得浮躁。文章认为,优秀的钢琴教师是抓好钢琴基础教育的路标,科学的练习方法是夯实钢琴基础教育的路基,并在双向性教学实践的基础上,对已出现的问题进行了研究和探索。     

Altering the Curriculum of the Home: Learning Environments for Korean and U.S. Students

ABSTRACT

The family and home environment are considered the most significant influences on children's development and learning. These factors directly influence student ability, motivation, and interest in learning. This study focuses on alterable factors in the home environment (i.e., homework time, attitudes, expectations, reading). A multiple-factor model provides a framework to discuss the family influences that appear to explain achievement differences. To gain perspective from international comparative studies, statistical findings highlight family practices in Korea and the United States. The implications from this article discuss altering the curriculum of the home, providing supportive family conditions, early intervention, and family–school collaborations. Altering constructive factors in the home environment in any culture may strongly influence children's learning and development.     

Social influences on use of cigarettes,e-cigarettes,and hookah by college students

ABSTRACT

Objectives: (1) Compare social norms and perceived peer use between college student cigarette, e-cigarette, and/or hookah users and nonusers; and (2) determine variables associated with social influences. Participants: Undergraduate students attending a large university in the Southeast United States (N = 511). Methods: An April 2013 online survey assessed use of 3 types of tobacco, social norms, perception of peer use, number of smokers in life, exposure to secondhand smoke, and demographic characteristics. Results: Participants indicated greater acceptance of emerging tobacco products than for cigarettes and consistently overestimated the percent of peers who use various tobacco products. Males and current users had higher social norm scores for all 3 forms of tobacco. Conclusion: To counter marketing of alternative tobacco products, education about the dangers of their use needs to be implemented across college campuses as part of a comprehensive tobacco control strategy that also includes tobacco-free campus policies.     

Longitudinal influences of managerial support on employee well-being

A three-wave longitudinal survey of managers working for a food retailer (n = 148) assessed both job characteristics and individual well-being during a period of organizational restructuring. Repeated measures analysis of variance revealed significant changes in both job characteristics and well-being across the three surveys. In addition, longitudinal structural equation models were developed to model the relationships between job characteristics and two indices of strain (job satisfaction and mental health) over time, including the assessment of the relative fit of competing causal process models. After controlling for the temporal stability of all variables, both types of strain were predicted by a combination of prior strain, prior job characteristics and current job characteristics. More specifically, managerial support was found to influence job satisfaction both directly and through perceptions of role ambiguity and control. Mental health was consistently predicted by low current and prior work demands, and in addition was associated with high managerial support. These results suggest that interventions to enhance employee well-being might usefully focus on increasing managerial support. Recommendations for research intending to examine the direction of causal associations between job characteristics and strain are made.     

The challenge of introducing low-carbon industrial practices: Institutional entrepreneurship in the agri-food sector

Contemporary agricultural practices account for a significant share of greenhouse gas emissions. Inspired by the emergent literature on institutional entrepreneurship, we seek to explore mechanisms that affect an actor’s propensity to act in ways that imply suggesting and promoting emission-reducing practice changes. As influences originating outside the organizational field are assumed to constitute such mechanisms, the paper explores their role through a case study of a project run by a public agency. Unlike extant theory, results show that the agency’s propensity to act is not necessarily enhanced by extra-field influences but that such influences also limit the scope for suggesting change that challenges existing industrial practices.     

罗丹雕塑对李金发诗歌的影响

李金发是一位雕塑家,他的诗歌创作与雕塑有着密切关系,并且直接受到罗丹雕塑的深刻影响。他的不少诗作是对罗丹雕塑的感悟和咏叹,他对罗丹爱情题材的雕塑作品尤其倾心,罗丹雕塑表现宇宙动象的艺术手法是李金发师承的重点。李金发的诗是象征的,亦是写实。     

论泰德·休斯诗歌的外来影响

英国桂冠诗人泰德·休斯是一个具有国际意识的艺术家.休斯早期诗歌受美国新批评派影响,60年代又受到超现实主义诗歌影响,其诗作呈现出超现实主义倾向,休斯在中后期开始对道家思想产生浓厚兴趣,他的诗歌因而呈现强烈的道家思想倾向.休斯兼收并蓄,不断丰富自己的诗歌创作,形成了自己诗歌独特的品性.     

决策的发展性研究进展

独立自主地做决策对青少年的成长具有重大意义.决策的发展性问题的研究有利于规范青少年的行为,促进其社会化进程.关于决策发展性的争论导致对决策问题的研究不可能获得普遍认同的结论.争论的焦点主要集中在:决策能力的构成成分有哪些;非认知因素、社会情境对青年和成人的决策能力影响是否是相同的;决策发展的本质是什么.综观各个理论派别的观点并做简要的评论,由此可以展望有关决策的发展性未来研究的方向.
