The aging male in the 21st century

Background.?Prostate cancer incidence varies significantly among different ethnic groups. However, the report concerning the clinical outcome after radical prostatectomy (RP) in the low incidence Asian population is still limited. We aimed to compare the clinical outcome in patient treated with RP among different ethnic groups and to identify significant prognostic factors in Taiwanese patients.

Methods.?A total of 341 patients with clinical localized prostate cancer undergoing curative RP in three medical centers in Taiwan were included in this study. Ethnic group comparison was performed using the CaPSURE, SEARCH databases from United States (US) and one large European series. The Kaplan–Meier analysis and Cox proportional hazard model were used to identify significant predictors for prostate-specific antigen (PSA) recurrence.

Results.?Compared to the Caucasian white population in the US and Europe studies, the Taiwanese population have higher age at surgery and higher pre-operative PSA level. With mean and median follow-up of 39.1 months and 31.0 months (range 5–120 months), 127 men (37.2%) had PSA recurrence which was significant higher than the Western series. Significant predictors for PSA recurrence identified in the post-operative overall model were PSA level, pathological Gleason Score, pathological tumor stage and lymph node metastasis.

Conclusions.?The clinical outcome of Taiwanese male with prostate cancer post-RP appears inferior to the Western country, which is largely due to delay surgery at higher PSA level. Earlier diagnosis and treatment may improve the cancer control of RP.

Writing from practice

This study investigates the effects of integration change on the integration success of German acquisitions in Poland. It is argued that the degree of integration change has a positive impact on two success measures, namely, economic growth and efficient co-operation, in the acquisition target. It is further argued that process transparency, participation and positive reinforcement are moderators in this relationship between degree of integration change and integration success. Hypotheses are tested on 521 Polish employees from twenty-nine German acquisitions made in Poland between 1991 and 1999. The results show that there was a positive relationship between degree of integration change and integration success as expected and that only process transparency emerged as a significant moderator of this relationship. Consequences for post-acquisition management after German acquisitions in Poland and limitations of the study are discussed.     

“第三条道路”的社会福利主张对我国构建和谐社会的重要启示

在构建和谐社会的过程中,应当吸收、借鉴国内外推行社会福利方面政策的经验。作为引起了20世纪80年代以来世界各国社会福利领域发生重大变化的“第三条道路”强调“无责任即无权利”的新原则,提出了积极的福利政策,主张建设社会投资型国家。其中注重人力资本投资、积极的福利政策和发展公民社会对我国构建社会主义和谐社会提供了重要启示。

互文性新论

文学艺术和科学领域都有互文性现象存在。文学艺术中的互文性是产生新意、形成对话的积极互文性。互文性对于文学艺术至关重要;科学中的互文性是精确转述他人原意、独白式的消极互文性,科学对自己的过去采取与文学艺术截然不同的态度,互文性对于科学来说无足轻重。互文性是一种意义于其中转换生成的函数关系(功能而非本体)。构成互文性必须具备三个要素:文本A、文本B和它们之间的互文性联系。     

浅析政治教学积极语言运用的德育功能

积极语言是通过语言引导自己和别人关注生活中美好的事物,发现和激励他人的优势和潜能,促进积极的人际关系。语言是教师在教育教学的媒介,如何通过积极语言的使用来有效提升教育教学效果至关重要。立德树人是教育的根本任务,政治学科在德育中发挥着特殊的作用,本文以政治学科教学为例,探究积极语言的使用对政治学科德育功能实现的作用。     

基于重现时间间隔分析的极端收益预测及交易策略研究

极端收益的预测在金融风险管理中非常重要。本文系统研究了极端收益重现时间间隔的统计规律，提出了一种基于重现时间间隔分析的早期预警模型，并对极端收益的重现进行预测，检验了模型在样本内外的预测性能；最后分别针对极端正收益和极端负收益的样本外预测结果，设计了看涨和看跌的两种交易策略，并以中国上证指数、法国CAC40指数、英国富时指数、香港恒生指数和日本日经指数为例，对交易策略的日均收益率进行了统计显著性检验。研究结果表明，极端收益的重现时间间隔具有右偏、尖峰厚尾和强自相关等典型特征；极端收益预测模型在样本内和样本外检验中都具有良好的预测能力；看涨和看跌交易策略在卖出区间均能有效地避开下跌阶段，看涨策略有更显著的盈利水平。
