THE NEW INTERNATIONAL DIVISION OF LABOR AND DEBT CRISIS IN THE THIRD WORLD

The advanced capitalist ccuntries are undergoing an industrial devolution as remarkable as the industrial revolution of the nineteenth century. The removal of high-paying jobs through automation and geographical migration destroys the main market of the center and precipitates debt crises in newly industrialized countries of the periphery which have followed export-oriented growth policies. This results in a new, internationalized form of the crises of iate capitalism and provides a new institutional foucs for crisis in the international banks. The paper examines this global process from the perspective of the geography of class struggle.

Spatial Patterns in Nutrient and In Vivo Fluorescence Distributions in the Marginal Ice Zone and the Seasonally Open Oceanic Zone in the Indian Sector of the Antarctic Ocean, in Austral Summer

Surface temperature, salinity, concentrations of silicate (Si) and nitrate + nitrite (N), and in vivo fluorescence (Fluor) were investigated in the marginal ice zone (MIZ) and the seasonally open oceanic zone (SOOZ) (32–40°E, 64–69°S) from February 23 to 28 1992. In the MIZ the mean Si and N were 67.8 ± 2.2 M and 32.5 ± 1.7 M, respectively. There was a trend that low N values coincided with high Fluor values. Observation conducted at one point (64°S, 38°E) revealed a diel variation pattern in Fluor. Applying this pattern of deviation from noon value, all Fluor data were normalized to value at local noon. In the MIZ a significant negative correlation was observed between the normalized Fluor and N but not Si. On the other hand, Si decreased continuously from south to north in the SOOZ and was negatively correlated with the normalized Fluor. Difference in Si concentration was about 30 M between the sea around 64°S and the MIZ, while the difference in N concentration was estimated as less than 10 M. If diatoms take up silicate and nitrogen at an approximate ratio of 1:1, additional nitrogenous nutrients other than nitrate and nitrite (e.g. ammonia, urea etc.) would be required. In this case, an f-ratio of lower than 33% is obtained. It is suggested that in the MIZ abundance of phytoplankton community dominated by non-diatom increases utilizing nitrate while in the SOOZ abundance of phytoplankton community dominated by diatoms increases consuming Si and regenerated nitrogen.     

Automatic equipment to monitor groundwater radon

Prototype instrumentation, able to automatically measure groundwater radon content variations, is presented. The equipment is made of stainless steel and has spherical valves with automatic and pneumatic control. The deemanation of the gases from the water is obtained by evacuating a suitable expansion chamber. The instrumentation can make discrete sampling ranging from 1 per hour to 1 per 99 hours. The equipment was tested in the laboratory: the efficiency was measured by means of a²⁶⁶Ra solution. A mean value of (0.65±0.07) count/s/Bq was obtained. A calibration test was carried out by comparing countings from the automatic equipment with those obtained by the standard laboratory cell. Results of an operational check over a period of approximately one year indicate that variations in radon at the calibration site are attributable more to meteorological than to tectonic causes.     

The Mobile Street Food Service Practice in the Urban Economy of Kumba, Cameroon

The mobile food service practice is one of multiple survival strategies adopted by poor urban households in Cameroon to maintain and expand the base of subsistence incomes, especially in the current surge of economic crisis. Though a fast-growing informal sector enterprise, it is still at an artisanal stage in urban Cameroon, creating an urgent need for a supportive policy environment that could have measurable positive impacts on improving the productivity, welfare and income levels of the micro-entrepreneurs. This study looks at the mobile food service practice in Kumba, Cameroon, in terms of its basic characteristics, the locational factors influencing its socio-spatial distribution, the critical success factors (CSFs) determining customer choices, and its impacts on the local environmental resources and quality of urban life. The mobile food service practice creates employment, generates income, and acts as a food energy-support instrument to the urban poor and local economic activities operating in Kumba. The vendors, who are mostly women, can make incomes that are 405 per cent of the national minimum wage and, thus, contribute financially towards the education, health and survival of their families. The paper provides some recommendations on ways to improve the efficiency of this sector so as to achieve sustainable economic and social development and to enhance empowerment thereof.     

Chasing a 'loose and baggy monster': almshouses and the geography of charity

This paper goes some way towards redressing the lack of geographical literature on charity through exploring the geography of the British domestic charitable sector. The size and geography of the third sector is outlined, followed by an analysis of how almshouses can be understood as inherently geographical and deeply embedded in local social networks of inclusion as well as exclusion.     

我国制造业集群分布现状及其发展特征

目前，在我国很多地区，例如长江三角洲和珠江三角洲，以个别市、县、镇或村为范围，集中某种产品的生产所形成的制造业集群表现出极强的活力和竞争力。集群中的很多企业根据不同技术能力，纷纷进入了全球价值链，已经使中国成为跨国公司控制之下的“世界工厂”。文章从目前局限性的资料出发，将这一现象的分布现状进行了分析，并对其发展特征进行了描述。认为，在新型工业化道路中，企业只有在本地舍作和结网，加强创新，才能有效地插入全球价值链，参与国际竞争。为此，需要通过政策的支持，鼓励合作的信用环境，使价值链上的各级企业以及利益相关者进行合作。     

美国外商制造业直接投资区域分异模式研究

本文以美国经济区为基本地域单元，以区位商和相关系数为主要研究指标，从一般投资区位和新建投资区位两方面研究了美国外商制造业直接投资区域分异模式。主要研究结论如下：外商制造业企业就业与美国制造业企业就业的区域分布很相似，但更倾向于集中在美国东南部；外商新建投资企业相对集中在新英格兰部分地区和东南部，得克萨斯和路易丝安那海岸地区，密苏里州和伊利诺伊州西部；外商新建企业倾向于分布在高人口密度区，但相关性没有美国本国新建企业强；外商新建投资企业与外商并购企业的分布略有不同。
