青年农民工幸福指数及影响因素实证研究

青年农民工是伴随中国改革开放大潮成长起来的一支新型劳动大军,是社会主义现代化建设的重要力量。在党和政府高度重视农村剩余劳动力转移的大背景之下,其生存和发展状况日益受到社会关注。运用幸福感指数量表及SPSS15.0,对山东省威海市220名青年农民工幸福指数进行测算及对其幸福指数影响因素进行回归分析,结果表明,青年农民工整体上对目前生活的满意程度不高,这与工资收入、工作时间、婚姻状况等密切相关,而与性别、文化程度、变动工作次数等因素相关性不强。

Assessing the Impact of Alternative Water Pricing Schemes on Income Distribution

The reform of water pricing policies may represent an effective instrument for enhancing the efficient use of water resource. However, policy makers fear that a change in the pricing methods may cause income loss for some farmers, and that this income inequality may generate public discontent and policy inertia. The aim of this paper was to compare some pricing methods in order to measure their effects on income distribution. The analysis focuses on the income distribution among different types of farms, and the income distribution between different social groups (landowners, capitalists and workers) in the short term. A linear programing model based on expected utility theory is used to take into account the effect of commodity prices and rainfall variability, which are among the most relevant factors affecting farmers’ income. According to the findings, water pricing schemes do not affect the income distribution among farm types, although a significant impact emerges on the distribution among social groups, and in particular on the wages of temporary workers.     

Identifying the factors behind fatal and non-fatal road crashes: a case study of Lahore,Pakistan

ABSTRACT

The study identifies the factors behind fatal and non-fatal road crashes in Lahore, Pakistan, by investigating 461 reported cases to Traffic Police Lahore that occurred during January–November 2014. Road crashes are categorized into fatal and non-fatal crashes and, because of the binary nature of the dependent variable, logistic regression is used to identify the factors behind these crashes. As a follow-up, discriminant analysis is employed to classify the factors related to fatal and non-fatal crashes. The logistic regression results reveal that females are at higher risk of fatalities than male drivers. Among vehicle types, rickshaws and cars are more involved in fatal accidents because both are growing at large on roads. Long trucks and trailers are also involved in fatal accidents, mainly because of their huge size and drivers’ risky driving behaviours. It is also noted that risk of fatalities is higher in case where two vehicles bumped each other. Speeding and overloading are the common behaviours resulting in fatal crashes. Better urban transport systems and strict compliance with traffic rules and regulations may improve road safety in Pakistan.     

生态省建设反思

针对呈方兴未艾之势的生态省建设,文章进行了反思。首先,生态省建设的提法是一种线性思维的结果,不符合一般的生态规律;其次,生态省建设的提法过分强调了生态环境的区域性特点,而忽视了其最根本的整体性和开放性特点;再次,生态省建设有可能导致省际间公害输出;最后,生态省建设有可能导致省际间生态不公平。     

基于印刷原稿的扫描仪色彩管理的研究

为了研究和解决扫描色差问题,本文按照ICC制定的开放式色彩管理标准,采用一元线性回归算法建立扫描仪色彩修正文件,实现了基于印刷反射稿的扫描仪色彩管理。研究中将原稿各实地色块的实测L＊a＊b＊值与经过扫描仪扫描后得到的L＊a＊b＊值进行比对,在此基础上采用一元线性回归的方法进行拟合,并通过分析不同纸张对扫描颜色偏差的影响,建立扫描仪的色彩修正模型;同时完成对3台不同扫描仪的色彩修正,开发出相应的扫描仪色彩管理软件。研究结果对入门级色彩管理的普及应用以及应用水平的提高都有促进意义。
