高职院校学生学习动机现状的调查与分析

调查结果发现,高职学生的成就动机不足,学习动机的社会取向偏低,现实性较强,自我效能感较弱。多元与变革的社会环境和文化场域,直接影响着高职学生的学习价值取向,进而对高职学生的学习动机产生重要的影响;无法获得积极的学习体验是影响高职学生内在学习动力的直接因素。     

论我国食品生产经营者的道德底线与法律底线

食品安全问题关乎人们的生命与健康,是一个重大的民生问题。近年来,我国在食品安全法律制度建设与立法方面虽有改观,但食品安全事故仍频发,这主要是由于少数食品生产经营者无视道德底线和法律底线造成的。分析导致食品生产经营者突破道德底线与法律底线的原因,确保他们不逾越道德底线和法律底线,是党和政府必须直视和解决的紧要问题。     

运输成本、劳动力流动与制造业区域分布

近年来,中国制造业的区域发展不平衡,其中的重要影响因素是什么?本文通过构建经济地理的分析框架,分析了运输成本和劳动力流动在中国特有条件下的作用机制。运输成本差异形成了制造业在沿海地区的选址优势,而这一优势和目前的高劳动力流动成本一起,形成了沿海高成本压力而内地收入低下的新空间“二元”结构。同时,我们计算了区域经济的实际数据对这一机制进行印证,假如这一局面继续维持,它将妨碍沿海和内地产业分工与均衡发展。文章还认为,因为经济集中的趋势是内生的,所以平衡区域经济发展的政策取向应该是促进性而不是限制性的。     

Individual attitudes towards the impact of multinational corporations on local businesses: how important are individual characteristics and country-level traits?

We study the importance of individual characteristics and national factors influencing individual attitudes towards the impact of multinational corporations on local businesses. Our sample includes more than 40 000 respondents in 29 countries from the 2003 National Identity Survey conducted by the International Social Survey Programme. We find that individual demographic factors and socioeconomic status, such as gender, age, income and education, are strong predictors of their attitudes. For example, income and education are positively associated with favourable attitudes towards the impact of multinational corporations (MNCs) on local businesses while age is negatively associated with individual attitudes towards MNCs. In addition, hierarchical ordered logit model results show that approximately 8% of total variations in individual attitudes around our sample mean are not explained by differences in personal traits. Instead, they are due to country-level heterogeneity such as, but not limited to, different degrees of openness or different aggregate income.     

Is unemployment good for the environment?

Environmental quality is a public good, potentially impacted by everybody. Individual level pro-environmental behavior affects environmental quality in the aggregate. Therefore, it is important to understand what causes individual’s pro-environmental behaviors to change. We quantify the causal effect of one determinant, unemployment, using an EU-27 population representative Eurobarometer survey. Drawing on results from the theory of the private provision of public goods, and recognizing that unemployment decreases income and the opportunity cost of time, we formulate testable predictions that unemployment will decrease the extent of pro-environmental behaviors that require monetary contributions and increase the extent of pro-environmental behaviors that mainly require time/effort. Instrumental variables regressions provide empirical evidence to support these hypotheses. Changes in the unemployment rate within a sub-national region provide the exogenous variation needed to identify the causal effect. Several supplemental questions on the survey provide evidence that environmental issues lose saliency and economic issues gain saliency when one becomes unemployed, suggesting that interested parties may wish to emphasize cost savings of pro-environmental behavior rather than environmental benefits during times of increased unemployment.

关于水利水电工程地质存在问题的探讨

水利水电工程建设与环境保护是一项长远的任务,是水利水电工程顺利进行的重要保证。工程地质工作的质量,对工程方案的决策和工程建设的顺利进行至关重要。由于地质问题引起的工程事故时有发生,轻则修改设计延误工期,严重时造成工程失事,给人民生命财产带来重大损失。由此可见,总结分析水利水电工程地质勘察过程中存在的问题,具有重要的现实意义。     

应用高精度磁测方法直接寻找磁铁矿体

通过1/1万的高精度磁法测量,在哈西亚图地区圈出了C1、C2、C3三个异常,从目前成果看,矿致异常的异常特征很明显:异常为南正北负,正磁异常大于负磁异常,峰值较高,当△T在3000 nT-8000nT区间时,梯度陡的磁异常区域,磁铁矿体埋藏深度较浅,一般小于20m,当△T大于8000 nT时,地表可揭露出磁铁矿(化)体。此次普查工作大致查明C2-1、C3磁异常为矿致异常,含矿岩性为矽卡岩,矿床属似层状矽卡岩型铁多金属矿床[4]。
