A low rate of natural increase, deriving from a disrupted age-sex structure, and net out-migration combine to account for a steady depopulation of Pskov Oblast. The introduction of industries providing additional male employment is recommended in the two principal cities—Pskov and Velikiye Luki—to correct the present predominance of women in industrial towns. Several measures (modernization of the countryside, promotion of truck-produce farming around the major urban centers) are suggested to keep more young people in rural areas and thus correct the lop-sided age structure there. Economic decision-making is viewed as a key factor in improving the demographic situation of a region.  相似文献

Some common assumptions about the form and use of migrants' remittances in the South Pacific are examined and questioned in the light of information from a micro-economic study of one group of remittance recipients in the flea market of Nuku'alofa, the capital of the Kingdom of Tonga. The findings of this study suggest that economic analysis and policy recommendations based on the existing macro-economic data on recorded remittances and other economic aggregates should be treated with caution. The unrecorded inflows of remittances in kind and the associated spread of the domestic informal sector have had some important implications for the functioning of Tonga's economy. There is some evidence to suggest that the growth of informal, international trade is fostering other significant changes in the domestic economy. The functioning of remittance-dependent economies such as Tonga is much more complex than existing economic analysis suggests, and involves substantial investment – not just consumption – with the emergence of entrepreneurs and the manipulation of dependence, rather than merely passive receipt of cash and expenditure focused on consumption.  相似文献

A review is undertaken of the nine species of Procytherura known to occur in Argentina and a new species, Procytherura serangodes sp. nov. is described. The global distribution of the genus indicates that it was more or less equally diverse and widely distributed in both hemispheres during most of the Lower and Middle Jurassic, but that in the Upper Jurassic and in the Lower Cretaceous, it became progressively restricted to the Southern Hemisphere. The widespread distribution of several Jurassic species of Procytherura, which occur in both Great Britain and Northwest Europe and in Argentina, is shown to be related to the availability of important migration routes, including the Tethys and the Hispanic Corridor. In the Lower Cretaceous, the very widespread distribution of Procytherura in the Southern Hemisphere, is used to support the existence of important routes along the eastern and western seaboards of Africa, the latter associated with the opening of the South Atlantic.  相似文献

There is an increasing use of palynological data to infer prehistoric agricultural activity. The uncritical acceptance of the technique of pollen analysis by archaeologists and palynologists is questioned. Attention is focussed upon the nature of clearance activity and problems of its inference from pollen spectra; the spatial distribution of palaeoenvironmental sites; and the proximity of such sites to those of prehistoric activity. The resolution apparent in peat and lake sediment pollen profiles together with problems of dating and temporal inference, are examined. In response to a perceived lack of formalization in palynological research, some simple models of clearance activity are presented. The complexity involved in environmental reconstruction is emphasized by reference to the use of supplementary data to augment the orthodox pollen record.  相似文献

回顾西方资本的历史,有利于认识它的今天,预计其未来行动. 马克思在<资本论>中科学地分析资本的融资流通等经济作用的同时,特意指出:资本需要流通,"只是在这个不断更新的运动中才有价值的增殖.因此,资本的运动是没有限度的."他进一步指出:资本家的目的"不是取得一次利润,而只是谋取利润的无休止的运动".马克思称之为"绝对的致富欲,价值追逐狂",而且,"资本来到世间,从头到脚,每个毛孔都滴着血和肮脏的东西".[1]  相似文献

The main goal of the paper is to study Jan Monk's contribution to the development of international gender geography, in particular in Spain. Our aim is also to explain the experiences and numerous connections among places, people and ideas that she has been weaving to foster international scholarship and, in this way, how she has challenged hegemonic approaches in feminist geography. Jan Monk comes originally from the Southern hemisphere and therefore she is well aware of the extent to which ‘Northern’ (or Anglo-American) ways of seeing the world define concepts, theories and ideas in geography (and also in feminist geography). Being an ‘insider’ and an ‘outsider’ as well as her sensibility to the important of place has permeated Jan's contribution to international gender geography.  相似文献

A landscape map of northern Tyumen' Oblast, an area of intensive oil and gas development, is used as the base for compilation of an applied landscape map evaluating the environment in terms of suitability for various means of transportation. In terms of such criteria as the carrying capacity of the ground, dissection of terrain and slope angles, climate, distances between trees, bog and lake cover, 16 regions offering distinctive conditions for transport development are delimited and mapped. The technique is offered as an aid in estimating transport-development costs and may be applied for similar purposes in other regions of USSR.  相似文献

Abstract

Over the past three centuries Italy has been the focus of numerous studies by French historians, who have taken advantage of the great wealth of sources available there. While no new synthesis has yet been achieved, we can identify certain main lines of development in French historiography. In the late 1970s and into the 1980s international relations and, especially, the relations between France and Italy were given the greatest attention, before a new focus on forms of sociability and political pedagogy began to be more common. However, the shifting of focus of historical studies to the centres of political decision making often coincided with less attention being paid to social stratification. Beyond these major themes, some researchers have reconstructed ‘global’ historical models, which have been characteristic of the renewal of post‐war French historiography.  相似文献

ABSTRACT

At the first ever worldwide international conference of psychology in Paris, 1889, one symposium included a round-table event devoted entirely to the neurodevelopmental condition of synesthesia. Details of this seminal gathering on synesthesia and its international reception have been lost to historical obscurity. A synesthesia study committee emerged from this meeting, as well as a new research tool. Moreover, the scientific findings discussed during this symposium would be echoed over a hundred years later, when a new wave of synesthesia research in the late-twentieth century arose. This article sheds new light on this seminal gathering and aims to answer the following historical questions: Why was synesthesia included in this conference? What science was discussed? Who were the members of the committee and how did they come to be involved? What were their contributions to synesthesia research before, during, and after the conference? What has history shown us about the impact of this symposium on the science of synesthesia?  相似文献

Although landscape research has not been set apart formally as a distinctive branch of geography in the West, the methods used in certain research programs in the United States and in Australia come close to the integrated areal approach to the study of the physical environment characteristic of Soviet landscape science. In the United States, landscape-like methods are used by the Soil Survey staff of the Department of Agriculture in its soil surveys of counties. In Australia, the landscape approach is used by the Division of Land Research of the Commonwealth Scientific and Industrial Research Organization in its reports on Australia's land systems.  相似文献
