风险投资对高新技术企业融资约束的影响研究——基于中国上市公司的面板数据

以2012—2017年上市的高新技术企业的面板数据,实证检验风险投资对高新技术企业融资约束的影响,并将样本按国有背景和非国有背景,成长期、成熟期和衰退期进行分类,深化研究。结果表明,风险投资能缓解高新技术企业融资约束,不同特征的风险投资机构对其融资约束影响也存在明显差异,非政府背景风险投资缓解效果更好;风险投资持股比例越高,高新技术企业的融资约束越低;联合投资对高新技术企业的融资约束影响不显著;风险投资有助于成长期和成熟期高新技术企业的融资约束的缓解,尤其是成长期的高新技术企业效果更为明显。

Buffering Against Sources Of Academic Stress: The Influence of Supportive Informational and Emotional Communication on Psychological Well-Being

This study examined college students’ psychological well-being as a function of both sources of academic stress and supportive communication. A total of 129 students completed measures assessing four sources of academic stress (i.e., pressures to perform, perceptions of workload, academic self-perceptions, and time restraints), psychological well-being, and two types of received supportive communication (i.e., informational and emotional). Pressures to perform, perceptions of workload, and time restraints were negatively associated with psychological well-being. In addition, the negative relationship between perceptions of workload and psychological well-being was strengthened when supportive informational communication and supportive emotional communication were individually and jointly low. Finally, the positive relationship between academic self-perceptions and psychological well-being was only significant when supportive informational communication was high.

规范与禁欲:新时期之前当代城市文学的处境

随着新民主主义革命的胜利,城市遭遇被改造的尴尬处境,城市文学创作相应受到之前解放区文艺观念的全面规约。经过关于城市小资产阶级可不可以作为作品主角的争论以及对《我们夫妇之间》的批判,城市社会世俗欲望的合法性逐渐被驱逐,原本就受到压制的城市文学更为受挫。直至"双百"时期,才出现了一批深入爱情禁区,潜在呈现城市世俗精神的作品,但它们大多很快就受到批判。此后,作为一部在革命意识形态规约下的上海的文学想象的长篇,《上海的早晨》以其独特的形态完成了新时期之前当代文学对城市的最后一次深情回眸。     

The effects of task constraints on the organization of interception movements

In the light of the intensity coupling effects reported in the literature, subjects' capacities for independently controlling the absolute velocity of their movement at the point of interception was evaluated by asking them to learn to propel orthogonally approaching balls, varying in their speed of approach, into target boxes placed at various distances from the interception point. As required for successful accomplishment of the task, movement velocity was found to be adapted to the distance to be covered, with the near target giving rise to lower velocities and the far target giving rise to higher velocities even when the conditions were presented in random order. Nevertheless, even though target distance accounted for a substantial proportion of the total variance, a small but significant effect of ball approach speed on movement velocity was found, suggesting that intensity coupling is a persistent but modulable phenomenon in interception tasks.
