中国南方岩溶水资源特点及科技工作的思考   总被引:2,自引:0,他引:2  
中国南方岩溶区是我国最大的连片裸露岩溶石山地区,分布面积约 54万平方公里,居住 1亿多人口。但由于强烈的岩溶发育和生态退化,该地区也是我国严重缺水的地区之一。因此,针对不同的岩溶水资源特点,采取多层次、多方位的科技工作方法是解决该地区缺水问题的根本科学途径。  相似文献

Four stakeholders are involved in corporate travel: management, travellers, travel suppliers and travel management companies. A successful corporate travel management process is dependent on cohesion of values between these stakeholders and pursuit of common goals. Value conflicts can influence the effective management of the process. The purpose of the study was to propose a model which recognises value conflicts, the interdependence of stakeholders and incorporates common goals. The so-called ‘Soft Value Management Model’ was selected and conceptualised in the context of corporate travel management. This study defined and surveyed each stakeholder group in terms of their values and objectives on travel management information; travel policy and compliance; travel management company partnerships; and travel expenditure processing. Quantitative and qualitative techniques were used. The results show that value conflicts exist between stakeholders. The model provides a theoretical foundation against which an effective travel management process can potentially be measured.  相似文献

核心-边缘理论提供了一个关于区域空间结构及其形态变化的解释模型。以陕西省为例,利用核心—边缘理论研究了入境旅游区域空间结构的时空演变及关键影响制约因素。研究结果显示,陕西省入境旅游区域核心-边缘空间结构发育典型;西安市入境旅游规模首位度十分明显,处于陕西省入境旅游区域发展的核心支配地位,其他城市处于边缘地位;入境旅游区域空间结构呈核心集聚型,核心城市的极化效应明显;陕西省各城市资源禀赋、经济规模、航空运输条件、对外经济联系、旅游接待能力等是导致这种核心-边缘空间结构形成的关键影响制约因素。  相似文献

Many women interact with the South African social security system in relation to the Child Support Grant (CSG), which is social assistance payable for children living with low-income caregivers. This paper explores women's accounts of how the CSG serves to protect and respect dignity, a foundational value in the South African Constitution. Drawing from focus groups and in-depth interviews with female CSG recipients of working age, it is argued that whilst the experience of using the CSG does protect dignity in certain important respects, other aspects including the application process, the small amount of the grant and negative discourses associated with the status of being a CSG recipient were experienced by many as erosive of dignity.  相似文献

ABSTRACT

Youth unemployment continues to be a burden and concern for the South African government. Being economically insecure, the situation is dire with the government needing to provide resources to a population who should be economically independent. There is a need to look at the social determinants of economic insecurity among youth in South Africa. Family formations could either promote or inhibit economic well-being. This article aims to assess whether economic security improves as youth enter into unions and/or have children. The South African National Income Dynamics Study is used. Unmarried youth with no children are measured at baseline (2008) and followed up over time to examine whether economic security status changes as union status changes. Results show that while economic security, employment (from 7.61% to 25.67%) and net income per month (from 19.48% to 32.79%) increase over time, youth who marry but have no children have the lowest risk of economic insecurity (relative risk ratio?=?0.02, p < 0.05) compared with those who remain unmarried but have children. Special attention needs to be given to youth who have children and are unmarried and among those who marry and have children soon after.  相似文献

Abstract

By estimating a dynamic panel-gravity model of bilateral foreign direcr investment (FDI), this article investigates the location determinants of inward FDI in South and East Asia and assesses their short-run and long-run effects. The econometric results highlight the importance of the vertical specialization-, trade-, and international integration-related location factors. The gravity-specific variables are also found to be significant location determinants, whilst some of the traditional determinants are found to have either a weak or statistically insignificant effect (except host-market size) on inward FDI in South and East Asia.  相似文献
