India’s Social Development in a Decade of Reforms: 1990–91/1999–2000

The economic reforms initiated in India in 1991 have brought about visible upliftment of economic conditions of the country. This paper examines if the economic process is associated with an enhancement of India’s social development in equal measure in the reform decade of nineties. Ray (1989) considered thirteen social indicators of India and constructed the country’s social development index (SDI) as a certain weighted average of the selected indicators, for the years between 1950–51 and 1975–76. The present work broadly follows Ray (1989) in tracking the social development in the decade of economic reforms from 1990–91 to 1999–2000. The movement of SDI in nineties has been compared with the movements of India’s per capita income and plan expenditure on the social sector. The results show that though there has been growth in the social sector, it is not by far quite encouraging and perhaps more needs to be done in the social sector.

Applicability of a Neuroprobabilistic Integral Risk Index for the Environmental Management of Polluted Areas: A Case Study

Recently, we developed a GIS-Integrated Integral Risk Index (IRI) to assess human health risks in areas with presence of environmental pollutants. Contaminants were previously ranked by applying a self-organizing map (SOM) to their characteristics of persistence, bioaccumulation, and toxicity in order to obtain the Hazard Index (HI). In the present study, the original IRI was substantially improved by allowing the entrance of probabilistic data. A neuroprobabilistic HI was developed by combining SOM and Monte Carlo analysis. In general terms, the deterministic and probabilistic HIs followed a similar pattern: polychlorinated biphenyls (PCBs) and light polycyclic aromatic hydrocarbons (PAHs) were the pollutants showing the highest and lowest values of HI, respectively. However, the bioaccumulation value of heavy metals notably increased after considering a probability density function to explain the bioaccumulation factor. To check its applicability, a case study was investigated. The probabilistic integral risk was calculated in the chemical/petrochemical industrial area of Tarragona (Catalonia, Spain), where an environmental program has been carried out since 2002. The risk change between 2002 and 2005 was evaluated on the basis of probabilistic data of the levels of various pollutants in soils. The results indicated that the risk of the chemicals under study did not follow a homogeneous tendency. However, the current levels of pollution do not mean a relevant source of health risks for the local population. Moreover, the neuroprobabilistic HI seems to be an adequate tool to be taken into account in risk assessment processes.     

A股上市首日超额收益影响因素的实证研究

在股权分置改革的背景下，运用多元线性回归模型的加权最小二乘法，对2004年1月1日至2007年12月31日期间发行上市的206只A股的实证研究，发现上市首日股票换手率、筹资规模和市场指数对上市首日超额涨幅具有较显著的影响；而发行价格、发行市盈率、发行前每股净资产、发行后实际流通股比例、发行方式及股权分置改革对A股上市首日超额收益影响不显著。     

Risk,trust and knowledge networks in farmers’ learning

This study reports on New Zealand dairy farmers’ access to and use of information as mediated through conditions of risk and trust within the context of their interpersonal social networks. We located participants’ reports of their information use within their perceived environments of trust and risk, following Giddens's [1990. The consequences of modernity. Polity Press, Stanford, CA] typology of trust and risk in pre-modernity and modernity. The research participants were constant users of interpersonal and print information from numerous sources, and monitored their incoming data in the light of strategic needs, reflecting their roles as both farming practitioners and business owners. Socio-spatial knowledge networks (SSKNs) combine individuals’ explanatory cognitive models of information acquisition and use with a micro-geographical analysis of their interpersonal networks. The participants showed characteristics of pre-modern, modern and even post-modern society in respect of their use of complex interactional forms, as well as a blending of individualistic and communitarian practices and concerns in their professional and personal lives.

中小企业发展与融资体系的构建

中小企业在其不同的发展阶段面临着不同的融资需求。文章以金融支持为主线,先从宏观层面上考察了企业融资结构分别对宏观经济波动和企业融资体系的影响,再从微观角度出发,试图在对中小企业各发展过程中融资行为、融资约束、融资结构等的分析中探求其“融资难”之所在。最后再依据我国的现实国情,并结合发达国家先进经验,探讨我国中小企业融资体系的构建。     

国内外公共突发事件应对研究述评

本文分别回顾了中外有关社会公共突发事件应急和企业危机管理的研究过程,从纷繁的研究文献中概括了有关突发事件应急的研究框架,认为对突发事件应急的研究可以归纳为静态系统和动态过程两个方面。近十几年来的研究重点主要放在了动态过程的研究上,而对静态系统的研究相对比较薄弱。     

平教会定县实验中的农村卫生工作之考察

中华平民教育促进会定县实验区在二十世纪三十年代创立了一套由村保健员、乡保健所、县保健院组成的三级卫生保健网,并在学校卫生、妇婴保健、传染病预防和疾病治疗等方面做出了显著的成绩,在当时产生了广泛的影响,对我们今天来说仍值得借鉴。     

物流的定义及其他——与王槐林、刘明菲先生商榷

物流的定义多种多样,林林总总,但都没有把生产过程包括到物流的活动中,只有王槐林、刘明菲先生主编的《物流管理学》却把生产活动当作物流的重要内容之一,并概括在物流的定义之中。这种观点如果成立,将给有关理论和实践造成很大混乱。
