企业信息门户:演进机制与实证观察

企业信息门户(EIP)已成为许多企业新一轮IT投资的热点.实证研究表明,企业的EIP工程不是简单的应用软件集成或门户网站建设问题,而是信息技术与企业内在的管理流程相互融合的变革过程.EIP的演进具有过程性和阶段性,EIP技术创新优势并不易持久.与企业战略和业务需求紧密结合、进行清晰的功能定位等有助于EIP的成功.     

改革开放以来农村五保供养制度模式变迁探析

改革开放以来,我国农村五保供养制度随着农村经济体制改革深化和社会的变迁,与时俱进,在改革中发展,目前基本实现了从农民集体内部互助共济的传统救助模式,到以国家财政供养为主,集体保障、土地保障和社会帮扶为辅的现代社会保障模式的历史性变革。2006年新《农村五保供养工作条例》的出台,不仅标志着我国五保供养工作进入了规范化、法制化管理的新阶段,而且也标志着与社会主义市场经济体制相适应的新型农村五保供养制度的基本确立。     

浙江模式:一个区域经济多重转型范式——多视野的三十年转型

基于经济转型多重性视点,本文从制度转型、工业化、城市化以及区域经济二重开放四个内涵,分别对"浙江模式"及其演进机理进行了分析.研究揭示:区域制度转型的浙江模式,是四个小区域模式的融合;区域工业化的浙江范式,是两个小区域工业化模式的聚合;区域城市化带有古典城市化的特征,"老板进城效应"突出;区域经济二重开放取先区际化后国际化的演进路径.浙江模式是这四个领域转型路径特征的融合.区域要素禀赋优势即个人商业才能的发挥与产业地方化及其集聚要求,形成转型的基础动力,这些动力促成了一种由基层到小区域,从小区域到较大区域再到省域范围的自下而上的倒逼式转型机制,由此赋予浙江转型以民营化的鲜明特征.但分析也表明,浙江模式的发挥,迄今仅限于地方政府有权处置的产业与行业范围,在超地方政府力量主宰的产业与行业,则显得无能为力.     

企业家人力资本与我国地区经济增长差异研究——基于跨省面板数据的协整和误差修正模型检验

自1978年改革开放以来,中国经济在保持年均10%左右增速的同时,东部与中西部地区经济发展水平的差异化也日益显现.通过对我国30个省区的面板数据分析,发现企业家人力资本对我国地区经济发展存在显著影响;经济发展水平较高的地区,企业家人力资本在经济中的作用也更为显著.因此,企业家人力资本丰盈程度的提高,将有助于提升欠发达地区经济增长水平,实现跨越式发展.     

汤显祖与湖州考论

本文细致考察了汤显祖与湖州的关系,主要包括三个方面:一是揭示了汤显祖与湖州董氏的关系,认为正是汤显祖的仇董心态导致了他对董斯张热情洋溢的书信采取了漠然置之的态度;二是考察了汤显祖与湖州臧懋循、臧懋中、韩敬、丁长孺、孙懋昭、凌濛初等十余人的关系;三是考察了汤显祖诗作中对湖州风光特产的吟咏,认为他至少来过湖州一次.     

远去与归来——一种跨越乡土社会的田野民族志方法论

远去与归来构成了一种方法论,这种方法论超越了乡土社会研究的村落传统.村落从来不是局限在村落的范围内的,通过行者的远去,村落的边界得到了跨越.同时考虑到归来取向的村落研究与远去取向的跨村落研究,一种田野民族志的方法论才堪称完整.     

青海民族民俗工艺的文化特征研究

本文认为青藏民俗工艺在文化上具有复功能性特征,主要表现在民艺器物本身多元复合和人们对于民艺器物在使用基础上赋予的多重意涵;受多民族文化、多元宗教文化的影响,其审美内涵被赋予了多重的文化元素.青藏民俗工艺的造物思想则表现为青藏各族民间工艺的造物思想表现为积极的实用原则,典型的原生思维方式和典型的宗教哲学思辨方式,青藏各族的工艺的本质是生活的艺术化、信仰的生活化、宗教的习俗化.     

Can the minimum living standard guarantee scheme enable the poor to escape the poverty trap in rural China?

The rural Minimum Living Standard Guarantee (Dibao) Scheme is the most important social assistance programme in rural China. However, how the rural Dibao programme affects household expenditures and whether it can enable the poor to escape the poverty trap are questions that remain largely unexplored. This study used data from the 2012 Rural Household Survey in China to investigate the impact of the rural Dibao programme on household expenditures. We found that the programme significantly improved the well‐being of low‐income households. Particularly, the programme significantly increased household expenditures on housing, education and health; furthermore, the impact was greater for households with educated household heads. However, the programme did not significantly affect household expenditures on food, transportation or farming inputs. The results imply that participation in the rural Dibao programme induces household investment in human capital, which could help to break the inter‐generational transmission of poverty and raise long‐run welfare.     

The impact of age,BMI and sex hormone on aging males’ symptoms and the international index of erectile function scores

Objective: To analyze the impact of age, BMI and sex hormone on aging males’ symptoms (AMS) and the 5-item version of the international index of erectile function (IIEF-5) scores in middle-aged and elderly Chinese men.

Methods: A population-based cross-sectional study was conducted in Jiashan County. A total of 969 men, aged between 40 and 80 years old, were admitted. Physical examination and the sex hormones were measured, and AMS and IIEF-5 scores were assessed.

Results: The oneway ANOVA analysis indicated older age groups had higher AMS total-scores, somatic and sexual sub-scores, and lower IIEF5 scores (all p?r_pairwise) analyses showed the significant associations between AMS and age or sex hormone (cFT, Bio-T, SHBG, and LH) levels, and similar for IIEF5. However, when age was adjusted, the correlation coefficients (r_partial) weakened, and correlation significance disappeared, except LH (for AMS: r_partial?=?0.096, p?=?.009; for IIEF-5: r_partial?= ?0.140, p?=?.001). Multiple linear regressions confirmed the influence of increased age and LH on the AMS and IIEF5 scores.

Conclusion: CFT, Bio-T and SHBG failed to yield any additional predicting information when age was adjusted. To improve the male reproductive health, future research should pay more attention on aging-related comorbidities and how to improve general wellness.     

Variable selection for semiparametric proportional hazards model under progressive Type-II censoring

Variable selection is an effective methodology for dealing with models with numerous covariates. We consider the methods of variable selection for semiparametric Cox proportional hazards model under the progressive Type-II censoring scheme. The Cox proportional hazards model is used to model the influence coefficients of the environmental covariates. By applying Breslow’s “least information” idea, we obtain a profile likelihood function to estimate the coefficients. Lasso-type penalized profile likelihood estimation as well as stepwise variable selection method are explored as means to find the important covariates. Numerical simulations are conducted and Veteran’s Administration Lung Cancer data are exploited to evaluate the performance of the proposed method.
