大学生拖延行为与未来时间洞察力的关系
The Relationship between College Students’ Procrastination and Future Time Perspective
 [PDF]


Advances in Psychology (AP) , 2014, DOI: 10.12677/AP.2014.46099
Abstract:
研究对大学生唤起性和回避性两类拖延行为、未来时间洞察力的状况进行了调查,并探讨了它们之间的关系,旨在丰富大学生拖延与未来时间洞察力的研究内容,为广大高校心理工作者提供理论与数据支持。研究采用分层整群抽样的方法选取607名在校大学生为被试,考察了大学生唤起性和回避性两种拖延以及未来时间洞察力的状况和特点以及它们之间的关系。主要研究结果如下:1) 总体来说,大学生拖延程度不高,但仍有部分学生有拖延行为的存在;大学生未来时间洞察力高于平均水平;2) 大学生唤起性拖延存在显著的性别和生源地差异;回避性拖延在性别、学校类型、专业和生源地上皆差异显著;未来时间洞察力在性别和学校类型上差异显著;3) 未来时间洞察力总分及各维度与唤起性、回避性两类拖延行为之间都存在显著负相关。
This study investigated college students’ procrastination of arousal and avoidance and future time perspective and explored the relationship between them, aimed at enriching the research contents of college students’ procrastination and future time perspective to provide theory and data support for the broad psychologists in colleges and universities. The study adopted stratified cluster sam-pling method selecting 607 college students as subjects, and investigated status and characteristics of college students’ procrastination of arousal and avoidance and future time perspective and the relationship between them. The main findings are as follows: 1) in general, the degree of procras-tination is not high, but it still exists among some students; the level of future time perspective of college students is higher than that of average; 2) students’ procrastination of arousal is different in genders and places students come from; procrastination of avoidance is different in genders, types of school, specialities and places students come from; future time perspective is different in genders and types of school; 3) there is significant negative correlation between total score and dimensions of future time perspective and procrastination of arousal and avoidance.

Abstract: 为考察预水解对后续二级生化处理的影响,结合无锡市城北污水处理厂实际运行情况进行了生产性试验研究。结果表明,对于工业废水占40%的城市污水而言,原水经过水解预处理后的可生化性得到提高,并且由于水解池在未满负荷运行的情况下对碳源有机物的去除率较高,对后续硝化脱氨、反硝化脱氮和除磷存在不同的影响。

Abstract:

生命周期对企业财务行为有着重要影响。本文以571家中小企业板制造业企业2010~2014年的数据为样本,用现金流量法界定企业所处生命周期,并对不同阶段的资本结构及其影响因素进行对比分析。实证结果表明,相对于成熟期和衰退期,成长期企业资产负债率和长期负债率更高。在企业生命周期的不同阶段,资本结构的影响因素也存在差异:成长期企业资产负债率与成长能力正相关,与非债务税盾负相关,而成熟期和衰退期企业资产负债率则受到盈利能力的负向影响;成长期和衰退期企业长期负债率受企业规模的正向影响以及成长能力和非债务税盾的负向影响,而成熟期企业长期负债率则与盈利能力负相关。

The enterprises life cycle always has a significant effect on financial behavior. In this paper, we construct a panel data containing 571 listed SMEs during 2010 and 2014 as samples. We use cash flow structure to measure life cycle of our samples, and aim at exploring and comparing the decisions of capital structure of SMEs in different life cycle. It turns out that compared with maturation and recession stages, the growth stage has higher Debt-Asset Ratio (DAR) and Long Term Debt Ratio (LTD); influencing factors of the capital structure are various among different stages. The growth has a positive effect on DAR in growth stage while non-debt tax shield has a negative one. But the probability and DAR in maturation and recession stages are negatively correlated. Besides, the firm’s size has positive effects on LTD in growth and recession stages while the non-debt tax shield and growth have negative ones. Probability is negatively correlated with LTD in maturity stage.

Abstract:
随着当前计算机技术和信息技术的高速发展,土地定级估价已经作为土地管理行业的一门基础性工作,借助计算机技术和数据库技术,依托地理信息系统(GIS)平台建立的土地定级估价信息化管理系统,能够改变过去传统的手工操作方式,减少人为干预程度的同时提高运算速度及精度。由此,本研究创新性的提出了基于矢量和栅格混合空间数据格式的土地定级估价因素因子数据库,通过最小路径、九宫格领域算法计算得到同样基于矢量和栅格混合空间数据格式的土地定级估价过程数据库以及土地定级估价结果数据库。基于矢量和栅格的混合空间数据库和土地定级估价处理方式很好的弥补了国内的土地评估单位基本只采用基于矢量数据格式计算的土地定级估价信息系统计算量大,精度不高,以及数据不完整等方面的不足,为提高土地定级估价工作的效率和结果的精确性提供了更优化的选择。最后以重庆市主城区为例,验证了该数据库和土地定级估价算法的可行性,并形成了重庆市主城区土地等级和基准地价数据库。
With the rapid development of computer and information technology, land grading and standard price appraisal is treated as a fundamental unit for land management. In order to change the traditional manual work process, reduce the human intervention, and increase the speed and accuracy of calculation, database technology must be added into this work and GIS based land grading and standard price appraisal database management platform must be established to meet this demand of land management. Due to this reason, the research put forward the innovative mixed vector-raster spatial data format to build the database of the factors and indicators for land grading and standard price appraisal calculation process and applied the cost distance and other spatial analysis algorithms to build the work procedure database and result database which are also generated on mixed vector-raster data format. This mixed format database and land grading and standard price appraisal procedures make up the deficiency of the most used land evaluation database system based only on vector data format in China, and overcome the problems such as big amount of calculation process, inaccurate results, and incomplete data. It also enhances the efficiency of land grading and standard price appraisal work and provides an optimized choice to get more accuracy results. At last, this research set the downtown area of Chongqing as the research area, demonstrated the feasibility of the database and algorithms for land grading and standard price appraisal work, and obtained the accurate results of land grading and standard price appraisal in the downtown area of Chongqing.
