对西部初中历史教学的思考

在我国的宏观调控以及其他各项法律政策中,西部大开发战略一直是党带领人们进行社会主义现代化建设中的主要任务之一,也是民族进步和成长的重要推动力.教育是推动社会发展的重要催化剂之一,在历史资源丰富的西部教育过程中,加强历史这门课程的教育,不仅是当地资源得到有效利用的展现,也是深化西部大开发主题的必然趋势.初中历史教学在整个历史教育过程中占据着基础作用,抓好这一关键环节,对于提高历史课程教学、促进西部大开发战略的迅速进展等方面都有着不可替代的作用.     

关于青海省优势产业发展的思考

面对西部大开发进程的推进,青海省做为西部一个资源大省和经济穷省,其经济发展应突出自己的特色,利用丰富的自然物质资源,增创新优势,走特色经济之路.应更加着力建设"四大支柱产业"、"四大优势产业".这是青海省整个国民经济和社会发展中带有全局性的重大战略问题,也是青海省实现社会生产力跨越式发展的关键.青海只有将资源的独占性与科学开发利用相结合,促进主导产业持续发展,稳定产业基地建设,才能在新一轮的市场竞争大潮申取胜,也才能在西部大开发中发挥更大的作用.

实现市场优化配置资源的必要条件

更新资源观念,确定资源商品的价值特征,建立和完善市场价格体系,阐述市场优化配置资源的动力机制,基本条件和必要条件。资源商品按供需状态,形成市场价格。资源配置主要指资源存量和增量的配置取向。通过市场机制优化配置资源,首先就需要有一个能反映资源稀缺程度的价格体系。这就是说市场价格不仅反映供需状态,同时必须反映资源的稀缺程度。这样才能按照价值规律通过市场实现资源的优化配置。     

美国西部开发三点启示

美国历史上开发西部对我国进行西部大开发有如下几点启示。灵活优惠的土地开发利用政策 ,有助于推进我国西部大开发进程1 9世纪美国为了鼓励更多的人向西部迁移 ,制定了灵活多样的土地开发优惠政策 ,极大地推动了西部开发进程。我国实行土地公有制 ,不可能用同样的方式来鼓励西部开发 ,但是完全可以制定其他多种优惠政策来调动西部开发的积极性。可以考虑将一定面积待开发治理土地以低价、无偿或先期注入资金扶持的方式 ,承包、分租或批租给某单位和个人 ,在治理开发的前期给予贷款、补贴、贴息、雇佣工人工资、医疗有保障等政策 ,规定几十…     

西部开发加大了钢材的内需

预计今年西部地区钢材需求量将突破2000万t。1999年6月17日,江泽民主席指出,加快中西部地区发展的条件已经基本具备,时机已经成熟。他强调,加快实施西部大开发是“中华民族发展史上的一件惊天动地的伟大事业”、“世界开发史上是一个空前的壮举”。西部地区指陕西、甘肃、宁夏、新疆、内蒙古、青海、四川、重庆、云南、贵州、西藏11个省市区。该地区占我国国土面积56%以上,总人口23%以上,已探明的主要矿产资源总量占全国的一半。与东部地区相比,具有资源丰富、劳动力充裕、投资成本低廉、市场广阔等优势。但进入80年代以来,东部沿海地区发展…

Cognitive person variables in the delay of gratification of older children at risk.

The components of self-regulation were analyzed, extending the self-imposed delay of gratification paradigm to older children with social adjustment problems. Delay behavior was related to a network of conceptually relevant cognitive person variables, consisting of attention deployment strategies during delay, knowledge of delay rules, and intelligence. A positive relationship was demonstrated between concurrent indexes of intelligence, attention deployment, and actual delay time. Moreover, attention deployment, measured as an individual differences variable during the delay process, had a direct, positive effect on delay behavior. Specifically, as the duration of delay and the frustration of the situation increased, children who spent a higher proportion of the time distracting themselves from the tempting elements of the delay situation were able to delay longer. The effect of attention deployment on delay behavior was significant even when age, intelligence, and delay rule knowledge were controlled. Likewise, delay rule knowledge significantly predicted delay time, even when age, attention deployment, and intelligence were controlled.

Effects of granulocyte-colony-stimulating factor and interleukin-2 on ascites formation and the survival time of nude mice bearing human ovarian cancer cells

This study assessed the effects of the Persian Gulf War on the psychological health and adjustment of military personnel in Hawaii and Pennsylvania who either deployed (N = 1,524) or did not deploy (N = 2,727) to the Persian Gulf during Operations Desert Shield/Desert Storm. All participants anonymously completed a questionnaire providing information on demographics, psychological and psychosocial health, deployment stressors, current life problems, current distress, and causal attributions of present problems. Results indicate that deployed veterans experienced significant levels of stress in-theater and continue to report significant stress in their lives today. Although considerable stress is experienced, the majority of veterans are handling it unremarkably. Implications for future deployments and the need for military-normed assessment instruments are discussed.     

K-ras mutations in nonmucinous ovarian epithelial tumors: a molecular analysis and clinicopathologic study of 144 patients

BACKGROUND: Coronary stent deployment failure may be more common in clinical practice than generally appreciated. The incidence of failed deployment in routine clinical practice and the clinical sequelae have not been described. This study sought to determine the incidence and consequences of failed coronary stent deployment and to identify clinical and angiographic characteristics associated with deployment failure. METHODS AND RESULTS: A series of 1303 consecutive procedures involving attempted coronary stenting were reviewed retrospectively. Failed stent deployment was defined as failure of the stent to be either delivered to or adequately deployed at the target lesion site. Clinical records and angiograms were reviewed and qualitative coronary angiography was performed for all cases of failed deployment. Deployment was unsuccessful in 108 (8.3%) cases involving 134 stents. Stenting was attempted as a primary procedure in 40%, as bailout in 18%, and for suboptimal angioplasty in 43% of cases. In 87% of cases, attempts were made to withdraw the stent from the coronary artery. Stent retrieval was successful in 45%, peripheral embolization occurred in 38% of patients, and in 4% the stent dislodged in the left main artery. In 35% of cases, additional stent(s) were successfully deployed. Deployment failure was associated with an overall in-hospital adverse outcome in 19% of patients, including 16% urgent coronary artery bypass grafting, 5% nonfatal myocardial infarction, and 3 in-hospital deaths. At 6-month follow-up, 39% of patients had had at least 1 adverse clinical outcome of death, myocardial infarction, or repeat target lesion revascularization. CONCLUSIONS: Failure to deploy stents is a serious and relatively common problem that is associated with significant morbidity and mortality rates. Improved deployment strategies, including new stent designs, are required to improve procedural outcomes.     

Energy Variability and Produced Water: Two Challenges, One Synergistic Management Approach Using Pumped Hydroelectric Energy Storage

A number of compounding issues currently encourage a different management strategy of produced water from oil, gas, and coal bed methane. Environmental and economic constraints make it desirable to deploy water and energy resources efficiently and effectively to meet the demands of our populace while maintaining and supporting environmental resources. The following paper will outline one strategy to put some of the onshore produced water to beneficial uses. In this approach, the produced water is first cleaned and then used to supply water for pumped hydroelectric energy storage (PHS) to deploy electric energy on demand, and finally release that water back to the watershed or appropriate application. The primary purpose of this work is to suggest that produced water and PHS may complement each other. Additionally, it is suggested that revenue from energy storage can help provide for the cost of treatment of produced water. Once treated produced water could be put to additional uses with the potential to also bring in revenue.

Feasibility of Rigidified Inflatable Structures for Housing

Rigidified inflatable structures (RIS) are thin, flexible membrane structures that are pneumatically deployed. After deployment, these structures harden because of chemical or physical change of the membrane. Because of this change, or rigidification, these structures no longer require pneumatic pressure to maintain their shape. With the aim of reducing the cost and examining the feasibility of RIS structures, a new material is proposed, developed, and evaluated. This material involves the formation of a semi-interpenetrating polymer network based on polyvinyl chloride and an acrylate-based reactive plasticizer. The economical and environmental performances of RIS using this new material are assessed by means of a case study. In this study, the performance of RIS technology is compared with that of a typical wood light-frame structure in the application of a small single-family house. The study indicates that the cost of ownership in present day value for the RIS is approximately 35% less than the cost of a comparable wood light-frame structure. The study also indicates that significant environmental benefits exist with the use of RIS. These structures use significantly less in terms of resources than do wood frame structures: approximately 2 times less in materials originating from nonrenewable fossil resources, approximately 2 times less in material originating from trees, and approximately 19 times less in materials originating from inorganic resources. The study concludes by delineating various means available to further increase the economical and environmental performance of RIS technology.
