视频网站盈利模式与运作创新

随着用户覆盖和影响力的不断提升,我国网络视频行业蕴藏的巨大市场价值正在逐步显现。但是,由于运营成本高、盈利模式单一且收入较低、受众还未建立付费收视习惯等综合因素,导致国内视频行业整体处于巨额亏损状态。虽然今年以来,优酷土豆合并与“视频内容合作组织（VCC）”的成立使得高昂的网络视频版权价格回归理性,广告收入快速增长,但行业亏损的现状在短期内还很难改变。需要在广告运营、技术手段、渠道扩展等方面探寻视频网站盈利的创新模式     

我国现代盐业企业发展战略研究

现代盐业企业是现代盐业产业的载体,是具有现代时代特征和专业性的社会生产组织系统,由海盐企业、井矿盐企业和湖盐企业三个部分组成。企业在现代社会中如何生存与发展是一个极具战略性的问题。面临21世纪新形势,我国现代盐业企业应当调整思路,制定适应新形势发展的企业战略。这个发展战略的目标是实现产业园区化、企业集团化等方面的企业现代化,以改善机制,推进企业现代化;培育核心竞争力,增强企业发展力等方面进行战略布局和规划,通过整合盐业企业,构建园区化的盐业生产格局等路径推进战略发展,实现战略目标。     

技术语境下的艺术

每一次根本性技术的发明都会改变人类的思维方式和价值体系。艺术变革也具有这种性质,现代艺术以强烈的革命态度表示出与传统价值观的决裂。艺术阐释的重心也从艺术创作和美学转向生产和消费领域。在这种情况下,法兰克福学派关于技术异化的批判,仍然具有警示作用;而艺术作为人类情感的一种表现形式、作为人文关怀的一种方式,在新时代的生态语境中,应该重新获取这些崇高意义。艺术变化与技术发展有直接的联系,除此之外,还与政治、经济、意识形态、精神、观念、艺术家等有着直接或间接的联系。综合考察这些因素,才能够探明艺术变革的真正原因。但未来发展情形仍然不明了,需要科学家和伦理学家共同努力。科技“由谁来控制”和“如何控制”是解决问题的核心所在。     

论聚居环境规划设计中的“曲”与“直”

以人类聚居环境建设为背景,通过对规划设计中"曲""直"不同层面的对比,分析由于观念问题所导致的认识上的偏差。从价值观念角度出发,探讨以"曲"为象征规划设计的深层内涵,提出其在人类聚居环境建设中的充分性和必要性。     

Family environments and the relationship context of first adolescent sex: Correlates of first sex in a casual versus steady relationship

Limited research has examined how family environments are associated with the relationship context of first sex, an important indicator of reproductive health risk. We use data from the 1997 National Longitudinal Survey of Youth to assess the association between the family environment - parent-parent relationships, parent-adolescent relationships, and family structure - and relationship context of first heterosexual sexual intercourse, distinguishing between the transition to first sex in serious and casual relationships. Twenty-five percent of females and 43% of males who had sex by age 18 did so in a casual relationship. All dimensions of the family environment were linked to the relationship context of first sex. Notably, higher parental monitoring was associated with a reduced risk of transitioning to first sex in a casual relationship versus no sex, and greater family routines were associated with a reduced risk of transitioning to sex in a steady relationship versus having no sex, for males and females. A strong maternal-adolescent relationship was associated with a reduced risk of first sex in a casual relationship but only for males. Additionally, in two-parent families, a strong father-adolescent relationship was associated with reduced risk of transitioning to casual sex, but only for females. Pregnancy and STI prevention programs should work with parents to foster positive parent-adolescent relationships, to become aware of their adolescents’ activities and to recognize that parents are important models for adolescent relationship behaviors.     

The source of Black-White inequality in early language acquisition: Evidence from Early Head Start

I compare language learning trajectories for Black and White children over the first 3 years of life using data from the Early Head Start Research and Evaluation study (EHSRE) in order to determine the timing and source of divergence in early language skill. Results indicate that that while controlling for racial differences in family background and a measure of the home language environment cannot entirely account for disparities in language acquisition, interactions between age, race and maternal education, and between race and a time-varying measure of the home language environment play a significant role. I show that returns to parental education and the home language environment, in terms of language learning, are higher for White children than their Black peers. Specification checks confirm that these results are robust to alternate definitions of child language and the home language environment, and that no interactions between race, age and any of the other covariates are significant. I discuss possible explanations for these race specific education gradients, including measurement error and test bias. In addition, I address relevant empirical issues in estimating language growth with respect to linguistic inputs and the home language environment.

基于新形势下上海引进外资出现的新情况、新问题,通过对上海投资环境、定位和区位的具体分析,建立上海吸引高端外资的系统框架,并提出上海在市场开放方面,应扩大外资进入领域,鼓励外资投向"上海制造"、"上海服务"、"上海创造"的高端产业,依次引导外资的产业结构升级;在投资环境方面,应建立统一和可预见的法制环境,完善社会信用制度,以此维护市场的竞争秩序;在市场准入方面,应放宽行业限制,不断调整和优化利用外资结构。     

以生态理论为基础建设职业高校生态图书馆

随着社会的不断发展,生态概念已经从生物学发展到整个人类社会科学,近10年,图书馆也开始研究如何建筑生态图书馆的问题。图书馆人也应该立足于人类的长远和可持续发展,注重生态保持,建设"绿色"、"低碳"、"环保"、"节能"的生态图书馆。文章从图书馆的建筑生态、环境生态、资源生态、人文生态等诸多方面分析了如何建设生态图书馆的问题。     

基于网络环境的研究生英语教学模式研究

哪些创业失败者更可能卷土重来?———基于松 － 紧文化与制度环境的跨国比较研究

高失败率是创业热潮中创业者必须面对的基本事实.创业失败在为创业者带来大量情绪与财务成本的同时,也提供了独特的学习经验.如何激活创业失败者卷土重来的激情是降低创业社会成本的关键.文章整合组织学习和创业认知理论构建了统一的创业失败学习理论逻辑,结合全球创业观察(Global Entrepreneurship Monitor)、世界银行和松-紧文化3个跨国数据库,考察了不同国家文化与制度环境下不同性别个体的创业失败经历对其创业选择的影响.研究发现:与没有失败经历的个体相比,有创业失败经历的个体更可能选择创业;高宽松度的国家文化、好的制度环境分别强化了这一关系;性别与文化宽松度对这一关系有显著的三重调节效应.即在高宽松度的国家文化下,有创业失败经历的女性创业者再次创业的概率更高.将性别角色差异纳入到创业失败的分析框架中,同时也扩展了创业失败的文化与制度分析.
