《藻海茫茫》因其特有的后殖民色彩而备受读者和批评家的关注。伯莎的"疯癫"及其纵火的行为,大多数评论者认为是遗传其母亲的缘故。此篇文章则认为这种"疯癫"是身份认同失败后身份迷失分裂的结果,伯莎分别在内部空间与外部空间中寻求认同却都以失败告终。其内部空间的认同在于与亲人的认同,外部空间的认同则为与黑人群体及白人群体的认同,内、外部空间身份认同的双重失败导致了伯莎偏激异常的心理及一系列行为,最终纵火而亡。  相似文献

中国职业教育立法在百年历程中进行过数次的制度构建。清末实业教育立法为民国职业教育立法奠定基础,在效法他国模式、学习其先进经验的进程中进行本土化的实践与探索,逐渐形成了比较完备成熟的职业教育法律体系。新中国成立后,单纯照搬苏联模式,全盘否定旧中国的立法体系,加上受到政治运动的影响和干扰,职业教育的发展及其法制建设大起大落。直到改革开放后,中国职业教育立法才逐步走上正轨,并取得重大成就。中国职业教育立法的百年历程,每一个时期都有其自身鲜明特点,需要我们认真归纳、总结和反思其中成败得失,为推动中国职业教育法制建设进程尽绵薄之力。  相似文献

Aiming at the large deformation and support problems of high-stress and broken-expansion surrounding rock, and taking 1 000 m level roadway of Mine II in Jinchuan as the research object, an investigation on the deformation and damage of roadway surrounding rock and an analysis of its mechanism were carried out. The gray correlation theory was used in support scheme optimization design. First, causes and mechanism of deformation of the 1 000 m horizontal transport channel were analyzed through field investigation, laboratory test and data processing methods. We arguued that poor engineering geological conditions and deep pressure increases were the main factors, and the deformation mechanism was mainly the ground deformation pressure. Second, the gray correlation theory was used to construct supporting optimization decision method in the deep roadway. This method more comprehensively considers various factors, including construction, costs, and supporting material functions. The combined support with pre-stressed anchor cables, shotcrete layer, bolt and metal net was put forward according to the actual roadway engineering characteristics. Finally, 4 support schemes were put forward for new roadways. The gray relational theory was applied to optimizing the supporting method, undertaking technical and economic comparison to obtain the correlation degree, and accordingly the schemes were evaluated. It was concluded as follows: the best was the flexible retaining scheme using the steel strand anchor; the second best was the one using plate anchors on the top and rigid common screw steel bolt on the two sides; the ttiird was; the rigid common screw steel bolt in full section of roadway; and the worst is the planished steel rigid support. The optimized scheme was applied to the 1000 m level of new excavation roadway. The results show that the roadway surrounding rock can reach a stable state after 5 to 6 months monitoring, with a convergence rate less than 1 mm/d.  相似文献

��[Purpose/significance] Intelligence is an indispensable part of decision.Analyzing the factors affecting intelligence intervention in decision-making mistakes and broadening the scope of research on decision-making error avoidance has practical significance for avoiding the risk of decision-making failure.[Method/process] Based on the literature review and theoretical induction, a questionnaire survey was used to collect data and perform statistical analysis and empirical research on the data to verify the applicability of the model.[Result/conclusion] Through analysis, the management mechanism has a significant positive impact on intelligence intervention, intelligence attitude, intelligence culture and intelligence factors have an indirect impact on intelligence intervention. Therefore, only the construction of the normative management mechanism can embed intelligence work in all aspects of the decision chain to ensure scientific decision.  相似文献

Abstract

The development and deployment of technologies for delivering broadband services to homes in Australia are investigated using the ‘social shaping of technology’ (SST) approach. The focus is on the period from 1993 to 1998 when there were five main technological options for delivering residential broadband services: ‘hybrid’ fibre coaxial (HFC) cable; direct broadcast satellite (DBS); multipoint microwave distribution systems (MDS); ‘Integrated Services Digital Network’ (ISDN); and ‘Asymmetric Digital Subscriber Line’ (ADSL). The main broadband services planned for delivery to homes over this period were pay television and fast Internet access. A sequence of snapshots of sociotechnical relationships at critical times during the study period, termed ‘sociotechnological configurations’, is used to track the evolutionary pathway of the broadband technologies. The mapping technique assists in identifying key features and explaining the driving factors of the pathway, including why HFC cable emerged as the predominant technology, and two competing HFC cable networks were rolled out in capital cities at an additional cost of over $2 billion when a single network would have had ample capacity.  相似文献
