传统外贸贡献计算方法的反思及改进

传统的外贸贡献计算方法割裂了各经济变量之间的联系，没有充分考虑出口对国内消费和投资的影响，因而，这一方法存在低估外贸对我国经济增长的作用的倾向，有鉴于此，章在充分考虑各经济变量之间的内在联系的基础上，构建一个联立方程组以重新估算外贸对我国经济增长的贡献程度。     

Community-based Arts Program for Youth in Low-Income Communities: A Multi-Method Evaluation

This article reports on a multi-method evaluation of a national arts program conducted over 3 years in five sites across Canada. Statistical analysis involve growth curve modeling of five waves of data and interviews with participating youth and parents. The results indicate that high-quality arts programs have a significant effect on children’s in-program behavior and emotional problems. The findings from the qualitative interviews suggest that active recruitment, removing barriers to participation, and high parental involvement enhanced youth engagement. Perceived youth gains included increased confidence, enhanced art skills, improved prosocial skills, and improved conflict resolution skills.     

论希腊神话中英雄成长的一般模式

作为世界上保存最完整的神话,希腊神话以其独有的魅力征服了亿万读者,成为了世界文学中不朽的经典。希腊神话中的英雄们以过人的胆识、超人的神力和无畏的精神,一路斩妖除魔、造福四方,成为了引领时代发展的骄子。在这些形象鲜明的神话英雄中,珀耳修斯、柏勒洛丰、伊阿宋、赫拉克勒斯、忒修斯、俄狄浦斯等人脱颖而出,成为了其中的佼佼者。尽管这些英雄人物在成长蜕变的过程中有着各自不同的神奇经历,但都无一例外地经历了从离开故土到生死历练再到荣归故里最后悲剧落幕这一相同的人生轨迹。研究希腊神话中英雄成长蜕变的一般模式,将有助于我们更深刻地理解希腊神话中的哲学文化内涵,也为我们研究他国神话中英雄的成长模式提供启示。     

企业成长的经济学分析——一个金融维度的理论框架

已有的企业成长理论基本是从技术维度、组织维度和制度维度展开,在企业成长环境发生巨大变化的今天,其解释力正在减弱,由此需要一种新的研究视角。金融维度的企业成长理论认为,企业的历史成长与金融制度的演进互动共生,生成企业价值的二元化——实体价值与虚拟价值。企业成长的金融实质是企业追求实体价值最大化与虚拟价值最大化之间既统一又对立的矛盾运动。

基于价值网络视角的商业模式分类研究:以现代服务业为例

随着全球化进程的加快和信息技术的发展,产业间的界限日趋模糊,新兴的现代服务业已经与传统制造业逐渐融合,商业模式的研究视角也开始由传统的产业价值链向跨产业价值网络转变。构建基于价值网络视角的商业模式分析框架,依据截至2011年底中国创业板上的62家现代服务业企业,运用专家问卷打分的方法及计算机算法和程序进行聚类分析,共识别出6类典型商业模式,分别是:长尾式商业模式、多边平台式商业模式、免费式商业模式、非绑定式商业模式、二次创新式商业模式和系统化商业模式。

ABSTRACT

Data from Cycle 5 of the National Survey of Family Growth (NSFG) (1995) were analyzed to identify factors that could predict whether a woman 18-44 years of age would ever have sought to adopt a child. Of the 10,019 women in the specified age group overall, 508 (5.1 percent) had ever sought to adopt, including 5.4 percent of white women and 5.2 percent of black women. Multiple logistic regression analyses were conducted for all women and for white women and black women separately. Among women who were white, the likelihood of having ever sought to adopt increased under conditions of childlessness, a history of treatment for infertility and surgical sterility for non-contraceptive reasons, non-surgical sterility, or physical difficulty in becoming pregnant (subfecundity), and if the woman was married, older, had some amount of college education, and considered religion very important. Having received assisted reproductive technology treatment also increased the likelihood that women in this group had sought to adopt. The likelihood of having ever sought to adopt increased among black women who were childless, older, and surgically sterile for non-contraceptive reasons, non-surgically sterile, or subfe-cund. However, having been treated for infertility and the presence of “resource” variables (other than age) did not predict that black women would have sought adoption. Among women of all races, having been a foster parent to a child increased the likelihood that the woman had sought to adopt the child when the woman was also childless, had been treated for infertility, was non-surgically sterile or subfecund, and older. Having been a foster parent was a significant predictor among white women who were childless and had ever been treated for infertility. Results are discussed in terms of benefits and limitations of all analyses and in terms of their implications for practice, policy, and research.
