浅析殖民主义的双重使命

马克思认为殖民主义具有双重使命 :一个是破坏性使命 ;一个是建设性使命。马克思的殖民主义双重使命说是我们分析评价殖民主义的理论基础 ,起着指导我们全面、辩证地认识殖民主义客观历史的作用。     

试述西方法社会学"活法"理论的两种观点

社会法学家们使用同样的研究方法来考察法律,但视角不同,导致各自的“活法”内容有差异。庞德的理论观点是研究“活法”的开端,埃利希的理论则是研究的重点。庞德肯定了除国家制定法之外,还存在着法官法,法律和道德很难严格区分是法官法存在的原因。埃利希认为法的真正渊源是社会而非国家,许多保证社会秩序化的行为规则都是法。“活法”理论认为法源于社会有其合理之处,盲目扩大法的范围和法律的变动性,有其不合理之处。     

Academic hardiness and academic self-efficacy in graduate studies

ABSTRACT

The purpose of the study was to measure graduate students’ academic hardiness (GSAH) and academic self-efficacy (GSASE) and to examine the relationships between the two. A total of 202 graduate students across disciplines were recruited to complete two questionnaires (GSAH and GSASE). Results of exploratory factor analyses showed that the GSAH and GSASE were reliable for assessing graduate students’ academic hardiness and academic self-efficacy. Comparing master’s and doctoral students’ scores in the GSAH and GSASE scales, we found that doctoral students outperformed master’s students. The findings also revealed that three dimensions of GSAH (commitment, control of affect, and challenge) were strong predictors of graduate students’ academic self-efficacy. These results confirm and strengthen the relation between graduate students’ academic hardiness and academic self-efficacy. This study calls attention to graduate students’ ability to recognize and appraise causes of their failure and to learn how to overcome academic difficulties.     

Hyperbaric oxygen therapy improves the effect of keloid surgery and radiotherapy by reducing the recurrence rate

Objective

Keloids are exuberant cutaneous scars that form due to abnormal growth of fibrous tissue following an injury. The primary aim of this study was to assess the efficacy and mechanism of hyperbaric oxygen therapy (HBOT) to reduce the keloid recurrence rate after surgical excision and radiotherapy.

Methods

(1) A total of 240 patients were randomly divided into two groups. Patients in the HBOT group (O group) received HBOT after surgical excision and radiotherapy. Patients in the other group were treated with only surgical excision and radiotherapy (K group). (2) Scar tissue from recurrent patients was collected after a second operation. Hematoxylin and eosin (H&E) staining was used to observe keloid morphology. Certain inflammatory factors (interleukin-6 (IL-6), hypoxia-inducible factor-1α (HIF-1α), tumor necrosis factor-α (TNF-α), nuclear factor κB (NF-κB), and vascular endothelial growth factor (VEGF)) were measured using immunohistochemical staining.

Results

(1) The recurrence rate of the O group (5.97%) was significantly lower than that of the K group (14.15%), P<0.05. Moreover, patients in the O group reported greater satisfaction than those in the K group (P<0.05). (2) Compared with the recurrent scar tissue of the K group, the expression levels of the inflammatory factors were lower in the recurrent scar tissue of the O group.

Conclusions

Adjunctive HBOT effectively reduces the keloid recurrence rate after surgical excision and radiotherapy by improving the oxygen level of the tissue and alleviating the inflammatory process.

     

酸催化丙烯醛水合规律的研究

以磷酸、硫酸及磷酸-三乙胺缓冲溶液为催化剂进行丙烯醛水合反应,考察了温度、时间、酸度、不同类型酸等因素对水合收率的影响。在间歇反应器中,当温度为70℃,时间为3h时,催化水合效果较好,结果表明催化效果与体系酸度成正比,H 的来源与催化活性无关,同时研究发现以缓冲溶液为催化剂效果要优于单酸催化。     

远程监视计算机屏幕的Java实现

在网络管理中,我们经常需要对管理的计算机进行监督,最简单的做法是对被管理的计算机屏幕进行屏幕监视.这样的工具很多,如"冰河"等远程控制软件,这些软件功能强大,但都是商业软件.我们完全可以使用Java JDK1.5的Robot类做出一个简单的屏幕监视软件.Robot对象可以完成对"屏幕"像素的快照.Java应用程序中可以直接调用此类的对象,完成对特定应用程序的屏幕截快照,如果将此功能配合网络,便可以轻而易举地实现对被管理的计算机屏幕的监视.本文向大家介绍如何用Robot类并给出应用实例.

小组合作学习的认识

小组合作学习是一种有效的现代教学理论和策略。从理念上讲,它包括互动观、目标观、师生观和情境观;从意义上讲,它有利于培养学生的社会适应性、自主性和独立性,为学生提供了更多的锻炼机会,使每个学生获得成功的体验;从策略上讲,可采取创设氛围、合理分组、促进交流和学科的沟通等方式。
