知识经济与强化人类活动的主体性效应

知识经济的发展，使知识和创新，成为人类活动的强大动力，人类的实践活动迈入了崭新阶段。人类的潜在智慧和才能，正源源不断地释放出来，转化为对象性存在，充分展示了人类活动的主体性效应，与此同时我们也必须正视人类活动的反主体性的效应。正确处理主体自觉能动性和客体自然性之间矛盾，是强化人类活动的主体性效应，防止反主体性效应的前提条件。     

Visual experience for autostereoscopic 3D projection display

In order to investigate visual experience for watching the autostereoscopic three‐dimensional (3D) projection display, we conduct a subjective evaluation experiment by a questionnaire when viewing video clips. Factor analysis is adopted to classify the evaluation items for the perpetual constructs of visual experience. Then a mixed design with repeated measurement analysis of variance with dimension and display duration as factors is carried out on the evaluation data to check the factorial effects and interactions for statistical significance. The results of factor analysis extract five factors including visual comfort, image quality, distortion, naturalness, and presence, which can be used as comprehensive indicators to evaluate the autostereoscopic 3D projection display. The results of analysis of variance indicate that image quality, which is used to assess two‐dimensional contents, is no longer applicable. It is necessary to give consideration to depth when evaluating 3D visual experience. Although 3D scenes enhance the overall subjective performance such as naturalness and presence, the health issues and stereoscopic distortion related to the introduction of depth cannot be ignored.     

Understanding taxi driver＇s cruising behavior with ZIP model

The taxi drivers＇ cruising pattern was learned using GPS trajectory data collected in Shenzhen, China. By employing zero-inflated Poisson model, the impacts of land use and previous pick-up experience on cruising decision were measured. The cruising strategies of different types of drivers as well as the top one driver were examined. The results indicate that both land use and previous pick-up experience affect travel behavior with the former＇s influence （7.07 × 10-4 measured by one of the coefficients in zero-inflated Poisson model） being greater than the latter＇s （4.58×10-5） in general, but the comparison also varies across the types of drivers. Besides, taxi drivers＇ day-to-day learning feature is also proved by the results. According to comparison of the cruising behavior of the most efficient and inefficient driver, an efficient cruising strategy was proposed, that is, obeying the distribution of land use in choice of cruising area, while learning from pick-up experience in selection of detailed cruising location. By learning taxi drivers＇ cruising pattern, the development of measures of regulating travel behaviors is facilitated, important factor for traffic organization and planning is identified, and an efficient cruising strategy for taxi drivers is provided.     

高职学生主观幸福感调查及其对策分析

主观幸福感是衡量个体生活质量的重要综合性心理指标,对高职学生在校学习和个人发展起到重要的促进作用。对苏北地区三所高职院校学生的主观幸福感进行调查研究时发现:主观幸福感在性别、年级和专业上的差异显著,女生主观幸福感得分高于男生,文科生显著高于理科生,大一学生显著地高于其他年级,主观幸福感的城乡差异不显著。从引导高职生树立积极的人生观、幸福观,塑造健康人格、提高综合素质,优化外部环境、健全社会支持体系和加强对特殊群体关怀与心理教育等方面探讨主观幸福感的提升策略。     

大学生负面评价恐惧、人际关系困扰与主观幸福感的关系研究

以569名大学生为被试,采用简明负面评价恐惧量表、大学生人际关系综合诊断量表及总体幸福感量表进行问卷调查,探讨负面评价恐惧对大学生主观幸福感的影响过程及人际关系困扰的中介作用机制。结果表明：负面评价恐惧女大学生得分显著高于男大学生,并存在显著年级差异;人际关系困扰总分及待人接物、异性交往两个因子男大学生得分显著高于女大学生,并在交际交友和异性交往两个因子上存在显著年级差异;大学生主观幸福感性别和年级差异不显著;负面评价恐惧与人际关系困扰总分及各因子呈显著正相关,与主观幸福感呈显著负相关;负面评价恐惧对主观幸福感有显著的直接效应,人际关系困扰在负面评价恐惧与主观幸福感之间起部分中介作用。     

辽宁省水利保障能力评价模型研究

为了研究辽宁省水利建设能否保障该省区域经济社会可持续和谐发展,以辽宁省第一次全国水利普查成果为依托,建立一套水利保障能力评价指标体系,利用模糊聚类综合评判模型和主客观赋权方法,对辽宁省各地市水利保障能力进行排序。评价结果表明,辽宁省各地市水利发展很不平衡,需要因地制宜,科学调整发展战略。
