Frailty models power variance function with cure fraction and latent risk factors negative binomial

In this article, we propose a flexible cure rate model, which is an extension of Cancho et al. (2011 Cancho, V.G., Rodrigues, J., de Castro, M. (2011). A flexible model for survival data with a cure rate: A Bayesian approach. J. Appl. Stat. 38:57–70.[Taylor &; Francis Online], [Web of Science ®] , [Google Scholar]) model, by incorporating a power variance function (PVF) frailty term in latent risk. The model is more flexible in terms of dispersion and it also quantifies the unobservable heterogeneity. The parameter estimation is reached by maximum likelihood estimation procedure and Monte Carlo simulation studies are considered to evaluate the proposed model performance. The practical relevance of the model is illustrated in a real data set of preventing cancer recurrence.     

“五四”文学审美批评的视野、建构与意义

"五四"文学审美批评是一种自成体系的批评模式,纵向视野与横向视野构成批评活动的两个基本维度,时间历时形态与空间共时形态交叉互渗。与此同时,"五四"文学审美批评体现为诚挚性、独创性和宽容性的复合内涵,彼此之间互为补充、渗透和制约,共同建构了整体性的批评氛围。"五四"文学审美批评作为一种话语诉求,在不同作家和批评家之间保持了良好对话与争辩,也就保持了相对自由与独立,在启蒙背景下彰显出全面的审美阐释,为新文学的自由与自觉在理论上奠定了坚实基础。     

辩证法在东、西方发展的不同命运——兼谈哲学研究中的方法论问题

我们在辩证法研究中之所以出现种种困惑,就在于没有从范式的高度去看待东西方的研究成果。东西方学者的研究可以概括为两个范式＂：研究马恩辩证法之间关系＂的范式和＂关注辩证法应用＂的范式。这两种范式的形成,既与东西方学者的研究方式有关,又与西方人重视＂正的方法＂,中国人重视＂负的方法＂等文化传统相联系。在借鉴西方学者研究成果时,态度要非常慎重,要注意现成结论背后的研究方式与文化传统的差异。     

Positive youth development in Māori and New Zealand European adolescents through an adventure education programme

Within Aotearoa New Zealand there is growing interest in positive youth development (PYD). A PYD approach provides balance to narratives surrounding outcomes for youth and broadens our views of what we consider beneficial developmental outcomes. In the current study we used sail training as a method to promote PYD in Māori and New Zealand European adolescents. Specifically, 54 Māori and 37 New Zealand European adolescents completed the 7-day youth-development voyage on-board the gaffed rigged schooner, R. Tucker Thompson. We demonstrate that, for both Māori and New Zealand European adolescents, psychological resilience, self-esteem, and positive outlook on life increased from the first day to the last day of the voyage. In addition, we demonstrate that the increases in psychological resilience were driven by the social/collective identity adolescents formed with their group over the course of the voyage.

Tools for evaluating EU agricultural policies: An integrated approach

The aim of this paper is to propose a theoretical “multi-phase” strategy for analysing in dynamic terms the territorial impact of agricultural and environmental EU policy measures. This approach should also allow to evaluate the adjustment capability of farms as a function of the characteristics of different territories. The proposed methodology is illustrated by an example using data relative to the 41 provinces of Northern Italy. In the first step, a multivariate statistical analysis (MSA) consisting in Principal Component Analysis and Cluster Analysis leads to the identification of homogeneous clusters of territorial units. The territorial mapping is conditional to a predetermined set of indicators that takes into account different aspects of agricultural development. In a second step, Positive Mathematical Programming (PMP) allows to introduce the impact of agricultural policies (compensatory payments, price changes, etc.) returning different scenarios of land use and agricultural profitability. According to the outputs of the PMP, the third step consists in a new MSA for detecting any changes in the territorial mapping. Convergence analysis can then synthesise the impact of the different policy options.     

论悲剧的本质——对尼采悲剧哲学的阐释

悲剧问题是贯穿尼采思想的一个基本问题,也是理解尼采哲学的关键所在.但是显然地,尼采对悲剧之本质的澄清,是与其思想的内在变化和澄清相对应的.他首先在叔本华形而上学的意义上揭开了悲剧之本质的序幕,然后进一步阐明生命的本质是权力意志,而悲剧的艺术是生命本来的形而上学活动,是虚无主义的反运动.换言之,悲剧本质上在于肯定生命的权力意志,这种肯定只有通过永恒轮回才能实现其最大可能性.正是在这种意义上,尼采才称自己是第一位悲剧哲学家.     

替吉奥胶囊联合紫杉醇脂质体治疗术后复发胃癌的疗效观察

目的探讨替吉奥胶囊（维康达）联合紫杉醇脂质体全身化疗对术后复发胃癌的近期疗效及不良反应。方法 25例手术后复发胃癌入组,给予替吉奥胶囊联合紫杉醇脂质体方案（替吉奥胶囊按照体表面积给予40～60mg,2次/天,第1～14天;紫杉醇脂质体135mg/m2,第1天静滴90分钟;3周重复）化疗,患者均接受至少2个周期全身化疗后评价疗效。结果总有效率为48%（12/25）,其中完全缓解率8%、部分缓解率40%、稳定率24%,临床获益率达到72%。主要毒副作用有骨髓抑制、周围神经毒性及胃肠道反应。结论替吉奥胶囊（维康达）联合紫杉醇醇脂质治疗术后复发胃癌患者疗效肯定,毒副反应可以耐受。     

税务人员自我和谐与积极心理资本的相关研究

目的：探讨税务人员自我和谐与积极心理资本的关系。方法：采用自我和谐量表（SCCS）和积极心理资本量表（PPQ）对来自全国各地的256名税务系统公务人员进行测查。结果：①税务人员自我和谐与积极心理资本总体状况较好;②自我和谐总分及各因子在性别上不存在差异,税务人员心理资本及自我效能、韧性和希望因子存在显著的性别差异;③自我和谐总分及其分量表与心理资本总分及其分量表存在不同程度的负相关;④韧性因子和希望因子对自我与经验的不和谐以及自我的刻板性有显著的预测作用（t=-6．212～-1．992,P〈0．05）,希望因子能显著的预测自我的灵活性（t=7．885,P〈0．001）。结论：税务人员积极心理资本对自我和谐有重要影响,应当鼓励税务人员发挥积极心理资本的优势,提高自我和谐水平。     

城市老年人服务需求的实证研究

城市老年人服务需求的类型包括:健康需求、精神文化活动需求、日常物质生活需求、精神慰藉需求、社会交往需求、获得尊重的需求、自我实现的需求等。满足城市老年人服务需求的对策包括:政府要充分认识满足老年人服务需求工作的重要性和迫切性、建构网络化的老年人服务需求支持系统、充分发挥社区助老服务的功能、加大满足老年人精神文化生活需求和自我实现需求的相关服务设施的投入力度。
