某油气田混输管道沉积固相分析及清管研究

随着我国经济的快速腾飞,我国对原油的需求量也急速猛增。然而据统计的数据来看,能源需求虽然在迅猛增加,但与之相对的是原油的储存量增加十分有限。由于近期我国对道路等基础设施的投资逐年增加,所以对重油以及沥青的利用率也在逐年升高。中国由于其比较独特的大陆板块构造,其稠油的开发空间也比较巨大,储量估计已经达到了总体可开采石油储量的20%。其中代表产地以新疆的塔里木盆地和吐鲁番盆地为主。但与此同时,稠油因其特性,易发生管堵等诸多事故,因此对稠油运输时的清管研究非常必要。     

新余市山南井田含煤沉积环境与聚煤规律

以山南井田安源组大禾山段为研究对象,分析安源组大禾山段含煤地层的沉积特征及其沉积环境,指出安源组大禾山段主要形成于山麓相-冲积相-沼泽相-泥炭沼泽相,建立其聚煤模式。     

经济全球化与中东大都市的崛起

二战后随着经济全球化与城市化进程的深入,中东大都市得到了迅猛发展并成为世界城市等级体系中的重要节点。目前中东大都市已经初步具备了"世界城市"的特质,呈现出地区经济控制力增强,媒介信息中心、文化中心地位提升,以及国际国内劳动力聚集等特征。然而在经济全球化视域下,新国际劳动分工、全球性资本与技术的自由流动以及地方政府积极应对经济全球化的相关政策等,给中东大都市发展带来了巨大提升空间的同时,信息化程度低、城市经济应对经济全球化能力脆弱以及城市治理缺乏等也成为了约束当前中东大都市崛起的主要因素。     

Explaining trade policy in the Middle East and North Africa

This paper examines the evolution of trade policy in the Middle East and North Africa (MNA) countries since the 1960s. It shows that contrary to the current popular perception, until the 1980s MNA countries were generally more open than the rest of the developing world. That situation changed in the 1980s and especially the 1990s as most MNA countries maintained their trade policies, while many other developing countries proceeded with liberalization. The paper develops and estimates a political economy model of trade policy to search for the factors behind the initial relative openness of the region and its reversal. The results show that the pattern is related to the rise and decline of the region's resource rents, which affected the political weight of domestic producers versus consumers. Other factors are also considered, but they all seem to have secondary effects.     

农村中小学教师教育法制素质的现状调查与分析

农村中小教师教育法制素质的高低,关系着我国教育法制进程的快慢。调查显示:农村中小学教师教育法律知识偏低、法律意识淡漠、侵权现象严重。要改变农村中小学教师教育法制素质的现状,应该从增强教师的法律意识、完善学校内部规则、加强对学生法律知识教育等几个方面入手。     

苏州市中青年购买健康险产品消费行为研究

本文主要针对苏州市的年龄在20岁～60岁间的居民为研究对象,研究苏州市中青年消费者对于购买商业健康保险的购买行为。研究后发现,各生活形态集群对于未购买原因有比较显著的差异,而对于购买动机,给付偏好、购买评估准则以及产品利益等则基本相同。因而,对各大保险公司来说,针对不同的子市场执行相应的保险营销策略,则有利于提高消费者的购买意愿,提高投保率。     

Contextualising diversity management in the Middle East and North Africa: a relational perspective

This study examines the clash between diversity policies as designed in the West and the challenges in implementing these in the Middle East and North Africa region. We contribute to the role of context in diversity management by studying how HR managers deal with diversity policies when the Western approach and the local context are perceived as being incompatible. Twenty HR/diversity managers working for multinational companies in nine different countries in the Middle East and North Africa region were interviewed. The findings show that a manager's understanding of the interrelated nature of multilevel factors of the local context influences the strategies adopted. Three strategies to deal with the perceived clash are identified: forcing a Western approach upon the local country, a reframing strategy where existing policies are reformulated to fit the Western requirements, and a sensitive approach in which the local context is considered. The study suggests that multinationa.l companies have to adapt diversity policies to local multilevel factors of the country in which they operate.
