赣州稀土产业竞争力评价及提升策略

以江西赣州为代表的离子型稀土资源是世界重稀土原料的主要来源,其产业竞争力的评价与提升很大程度上关系着我国稀土产业的健康发展.通过从资源储量、资源价值、生产能力、技术水平、盈利能力等角度,对赣州稀土产业竞争力进行评价.研究表明,赣州在资源价值、生产能力、技术水平等方面在南方离子吸附型稀土产业中具有一定优势,但竞争优势具有很强的脆弱性,主要取决于资源价值.赣州稀土产业应在稀土产业链的应用环节启动整合,加快组建研发联盟,尽快形成本土价值链.      

赣南稀土产业集群化发展对策研究

江西省赣南地区蕴藏着配分全、品位高、易提取、放射性低的离子吸附型中重稀土矿.但普遍存在滥采乱挖、浪费资源、生产粗放、污染严重、产能过剩、低价竞销、应用滞后、缺乏创新等一系列问题.不能在资源优势的基础上形成带有核心竞争力和经济效益的优势产业.产品停留在原材料和低端稀土产品上,产业化水平较低,产品性能和技术含量不高,产业链短,产品附加值低.分析了赣南稀土产业的竞争力和存在的问题,建议加强对稀土资源的保护,严格控制开采量和出口量,并加大科研投入,扩大应用,提高产品科技含量,延长产业链,加速行业整合,培育龙头企业.

Results of treatment of cancer of the cardia

Cancer of the cardia is traditionally discussed with cardiac cancer of the lower portion of the esophagus and upper gastric cancer invading the esophagus, and the specific characteristics of cancer of the cardia have never been clearly defined. We reviewed the outcome of 172 patients with adenocarcinoma of the cardia who had undergone radical surgery between 1949 and 1994 in the Division of Gastrointestinal Surgery of the Cancer Institute Hospital. The centers of the tumors were located within 2 cm above and below the boundary between the esophagus and the stomach, and their longitudinal diameter was less than 8 cm. We divided the patients into an early period (1949-1979; n = 79) and a late period (1980-1994; n = 93), and focused on the historical transition. There were no differences in patient gender or histology between the two periods. However, the late period was associated with fewer cases of esophageal invasion and shorter longitudinal diameter, as the age of the population advanced. The number of advanced cancers such as the localized and infiltrative type had decreased, and early cancer and early clinical stage had become more common, but despite the fact that the number of early cancers had increased, extended dissection, such as thoracic and paraaortic lymph node dissection, was performed more frequently. By clinical stage, the long-term outcome markedly improved in Stage I patient in the late period, and tended to improve in Stage II and III patients. This appears to have been attributable to the prevention of micrometastasis by extended dissection, although the number of early cancers is another major potential cause. There were no differences in the outcome of Stage IV patients between the two periods, and further advances in multimodality therapy must be awaited. The range of resection is basically proximal gastrectomy, and if there are adequate indications, the prognosis is favorable. In view of the status of lymphatic flow and lymph node metastasis, and long-term results, lateroaortic lymph node dissection is important. Since the number of early cancer patients has been increasing, if intraabdominal recurrence is prevented, intrathoracic lymph node dissection will contribute greatly to the outcome of such patients.     

The effect of amount of possession of the trait of hostility on accuracy of perception of hostility in others.

Some theories of personality hold that an individual's perception of others is influenced by his own personality characteristics; more specifically, that a trait of low social value will be projected more into others, and that insight into the possession of these characteristics reduces this distortion. These 2 hypotheses were tested by having a group of college students rate each other (including themselves) on degree of friendliness or hostility. Agreement with group rating about self yielded the insight score. In general, the hypotheses were supported; the "friendly" Ss were most accurate in their perception of others, and insight was positively associated with accurate perception.

Comparison of rates of infection of two methods of emergency ventricular drainage

The rates of infection of two methods of external ventricular drainage in use at Atkinson Morley's Hospital--namely, (a) percutaneous drainage with Rickham reservoirs and (b) tunnelled ventriculostomies--were compared in this retrospective review. Percutaneous drainage of CSF with Rickham reservoirs was associated with a 27% rate of infection as identified by positive microbiological cultures; tunnelled ventriculostomy catheters had a 10% infection rate. The difference in the infection rate between the two methods was statistically significant (P < 0.015). Other variables examined, including the age and sex of the patients and the reasons for ventricular drainage, were not associated with an increased rate of infection. Most infections from either method were caused by a coagulase negative staphylococcus. The average duration of ventricular drainage before identification of positive cultures was 5.7 days for Rickham reservoirs and 6.0 days for ventriculostomies.
