基于多元主体参与的生态城市建设和管理

由于在城市化进程中社会资源过度损耗,损害了城市的和谐和可持续发展,从而提出了对于生态城市的建设和管理.对此,政府的管理能力是有限的,且单一主体也是不能够实现生态建设的.这就要求社会多元主体从意识、政策、机制等方面共同参与生态城市的建设管理.     

快速城市化进程中以"人"为本的城市文化初探

城市化是对人类社会产生最大影响的社会过程,城市文化是城市里人们生活环境、生活方式和生活习俗的总和,包括物质文化、行为文化、精神文化.我国现阶段正处在城市化的快速发展进程中,物质建设也取得了骄人成就,但与之相符合的城市文化却没有随之出现.文化,成为近年各城市关注的焦点,本文就快速城市化进程中以"人"为本的城市文化进行了初步探索.

新加坡城市土地集约利用及其启示

随着我国城市化进程的加快,城市规模扩张逐渐加剧,而我国可开发土地资源极其有限,如何解决城市土地集约利用成为急需破解的重要课题。新加坡作为高密度发展的城市国家,以其宏观的土地集约利用政策和成功实践实现了土地资源的高效集约利用,并保证了高品质的城市建设和可持续发展。本文主要介绍新加坡城市用地中住宅用地、商业用地、工业用地和交通用地等方面集约节约利用的政策和措施,并以大巴窑新镇为例进行详细分析,最后探讨新加坡城市土地集约利用对我国的启示,以期对我国城市发展提供借鉴和参考。

基于SPSS的人口增长与土地城市化关系分析研究——以南充市区为例

目前,中国正经历着前所未有的城市化进程,人口增长与土地城市化存在着密切的关系.认识和协调人口增长与土地城市化之间的关系对我国经济快速发展意义重大.本文选取了1993年到2008年南充市的相关数据,运用SPSS技术通过相关分析与回归分析,对人口增长、土地利用及城市化的关系进行了探讨.结果表明,人口增长使人们对住房的需求压力加大,也拉动了地方经济发展,还能引起土地城市化进程的加快,从而间接的影响土地城市化,以期为城市合理开发与土地利用提供理论依据.

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.
