托马斯·哈代：一位悲戚而刚毅的诗人——哈代诗歌的生态批评解读

托马斯·哈代是英国文坛最伟大的小说家之一。细读哈代的诗歌,不难发现其大量诗作中表达出超前、深刻的自然意识和生态思想：人与自然合二为一;对自然生态的忧虑和对人类摧残自然的谴责;对社会生态的忧患与对人类社会异化的叹息。生态批评理论为研究哈代诗歌提供了新的视角。     

论国家助学贷款补贴政策的生成基础

助学贷款是一种具有公益性的金融产品,市场并不能对其起到充分的调节作用,其突出表现是助学贷款的“贷款难”和“回收难”问题。在这种情况下,公共财政对助学贷款进行补贴,不但可以推动助学贷款发展,而且可以优化教育资源配置,促进收入再分配和宏观经济发展。因此,公共财政对助学贷款进行补贴,既是助学贷款发展的现实需求所致,也是公共财政履行自身职能的必然要求。     

基于生态学的大学语文教育研究

自然界的任何生物群落或个体的生存状况无不受制于生态系统。大学语文教育是认识过程、心理过程、社会化过程的运动系统,除具有生态系统一般的整体性等结构特征外,还具有自身生态结构的独特性。大学语文教育应当根据其生态结构的内在特征,充分发挥文字、文化、存在和生命四个生态圈的结构功能,采用“五步教学法”。     

新型农村合作金融组织发展问题研究

新型农村合作金融组织有效满足了农村金融需求,有力推动了农村经济发展。但在实践中,农村金融组织存在法律政策风险、融资风险、监管风险、管理能力风险。为促进新型农村合作金融组织持续健康发展,必须坚持统有规、放有度、管有序,推进合作金融法制化、监督管理制度化、经营管理专业化和政府扶持常态化。

Does state-mandated financial education reduce high school graduation rates?

Concerned about low levels of financial literacy among teens and the importance of their looming financial decisions as emerging adults, state policymakers have expanded high school personal finance graduation requirements. Did these added requirements create an additional barrier for students? Comparing students in states with and without standalone personal finance course requirements before and after the requirements went into place, I provide evidence that these requirements did not reduce graduation rates overall, by race, by gender, or by family income. Existing research quantifies improvements in debt and credit behaviors, and these findings suggest there are not simultaneous adverse effects overall or for at-risk students.

What Tahrir Square Has Done for Social Media: A 2012 Snapshot in the Struggle for Political Power in Egypt

While the debate rages on the role of social media technologies in the initial days of the Egyptian revolution of 2011, a more relevant research question today is the role of social media within an increasingly contested and turbulent political sphere. This article identifies three key modes by which social media is being exploited to impact political power, and uncovers the salience of each of these through 2 years of multisited ethnographies and interviews. First, I argue that political actors across the political spectrum, from liberals to Muslim Brotherhood (Ikhwan), are using technologies to build wider ranging, heterogeneous, and diverse networks of supporters, expanding their base from a more historically homogeneous core support group. Second, I argue that actors are working to build bridges between older and newer media platforms, recognizing that each platform is increasingly being shaped by the other. Finally, I describe some of the ways that technology is being used by activists to subvert their competition, promoting campaigns of misinformation and hacking at the expense of others.

Plant Nutrient Stealers

<正>Parasitic plants comprise about1%of the angiosperm plants,and they steal nutrients and other molecules from their hosts.Compared with fully autotrophic plants,parasitic plants are distinct in their physiology,ecology,and evolution.However,still little is known about the evolutionary origins of plant parasitism and the molecular mechanism underlying the parasitic lifestyle.The plants in the genus Cuscusta(dodders)are obligate parasitic
