在生死之间挣扎——论《挪威的森林》的生存意识

生存意识是日本文学涉及的重要主题,也是日本民族特有的文化表征。《挪威的森林》以其独特的艺术世界向世人呈现出一种独有的生存状态：缺乏信仰的都市青年物质的追求与消遣却无法释怀精神的孤独与苦闷。他们在日益物化、疏离的现代社会中无所适从,为此,在世外桃源般的精神寄托处经历了生与死的考验,并在其张力下表现出现代人孤独与焦虑的内心世界和浓郁的生存意识。     

The Econometrics of Ultra‐high‐frequency Data

Ultra‐high‐frequency data is defined to be a full record of transactions and their associated characteristics. The transaction arrival times and accompanying measures can be analyzed as marked point processes. The ACD point process developed by Engle and Russell (1998) is applied to IBM transactions arrival times to develop semiparametric hazard estimates and conditional intensities. Combining these intensities with a GARCH model of prices produces ultra‐high‐frequency measures of volatility. Both returns and variances are found to be negatively influenced by long durations as suggested by asymmetric information models of market micro‐structure.     

试论我国家族企业的生存优势成长劣势与发展对策

家族企业已经成为促进我国经济发展的一支生力军。家族企业这种经济组织具有较强的生命力,有其自身的生存优势,如家族文化的强大凝聚力、成本的节约、对市场的快速响应能力等。但家族企业在其成长过程中也存在人治化管理、决策的独断性、管理人才缺乏等诸多劣势。文章在分析我国家族企业生存优势与成长劣势的基础上,提出了促进家族企业持续发展的对策。

Measuring Youth Development: A Nonparametric Cross-Country ‘Youth Welfare Index’

This paper develops an empirical methodology for the construction of a synthetic multi-dimensional cross-country comparison of the performance of governments around the world in improving the livelihood of their younger population. The devised ‘Youth Welfare Index’ is based on the nonparametric Data Envelopment Analysis (DEA) methodology and allows for cross-country benchmarking and comparison over time. The value added of the youth index is to produce country-specific rankings and trace performance evolution with respect to indicators solely centered on youth, unlike other development indicators like the Human Development Index (HDI) which bundles many social and development indicators.

从现代性质疑角度看我国乡村现代性的构建

已经历现代性洗礼的西方发达国家纷纷质疑现代性,这为正从传统走向现代的我国乡村提供了前车之鉴。西方现当代对现代性所追求的主体性、同一性和消费主义的种种质疑,体现了现代性自身所具有的局限性。我国乡村现代性的构建应该突破这些局限,建设和谐乡村,保持乡村特色,引导农民追求和向往非物质化生存状态,以收获更具可持续发展意义的现代性。     

马克思人学的现代意蕴

马克思人学以实践的方式把握人的生存,从思辨人学转向实践人学,找寻当前人的生存问题;从人的生存出发理解实践,从实践形而上学转向实践人类学,审视当前人的生存问题;以生存实践性为基点探讨人的发展问题,从抽象发展观转向自由全面的现实发展观,审视人的发展问题.可见,马克思人学直入人的核心问题,即人的生存与发展两大主题,并以真实地实现其对人的生存和发展关切的品性彰显着其现代价值和现代意蕴.     

人自然生态--析《狼群中的朱莉》的生态思想

当今日益严峻的生态危机引起了许多作家的关注和思考。美国女作家琼.C.乔治(JeanCraighead George)创作的少年小说《狼群中的朱莉》(Ju lie of the W olves)从人与自然、自然的价值与权利、人类对自然的掠夺破坏等方面探讨了人与自然之间的关系,表达了人与自然应该和谐相处的理念。     

Defective models induced by gamma frailty term for survival data with cured fraction

In this paper, we propose a defective model induced by a frailty term for modeling the proportion of cured. Unlike most of the cure rate models, defective models have advantage of modeling the cure rate without adding any extra parameter in model. The introduction of an unobserved heterogeneity among individuals has bring advantages for the estimated model. The influence of unobserved covariates is incorporated using a proportional hazard model. The frailty term assumed to follow a gamma distribution is introduced on the hazard rate to control the unobservable heterogeneity of the patients. We assume that the baseline distribution follows a Gompertz and inverse Gaussian defective distributions. Thus we propose and discuss two defective distributions: the defective gamma-Gompertz and gamma-inverse Gaussian regression models. Simulation studies are performed to verify the asymptotic properties of the maximum likelihood estimator. Lastly, in order to illustrate the proposed model, we present three applications in real data sets, in which one of them we are using for the first time, related to a study about breast cancer in the A.C.Camargo Cancer Center, São Paulo, Brazil.     

Discrete and continuous bivariate lifetime models in presence of cure rate: a comparative study under Bayesian approach

The modeling and analysis of lifetime data in which the main endpoints are the times when an event of interest occurs is of great interest in medical studies. In these studies, it is common that two or more lifetimes associated with the same unit such as the times to deterioration levels or the times to reaction to a treatment in pairs of organs like lungs, kidneys, eyes or ears. In medical applications, it is also possible that a cure rate is present and needed to be modeled with lifetime data with long-term survivors. This paper presented a comparative study under a Bayesian approach among some existing continuous and discrete bivariate distributions such as the bivariate exponential distributions and the bivariate geometric distributions in presence of cure rate, censored data and covariates. In presence of lifetimes related to cured patients, it is assumed standard mixture cure rate models in the data analysis. The posterior summaries of interest are obtained using Markov Chain Monte Carlo methods. To illustrate the proposed methodology two real medical data sets are considered.
