When Professor Papageorgiou submitted his brief essay in the spring of 1982 (“Some Thoughts about Theory in the Social Sciences, GA [October 1982], pp. 340-46), I decided to use it as a vehicle to provoke a discussion of the issues he raised. I invited a number of scholars to submit brief and informal statements on these issues and these responses are assembled in the following pages. The variety of styles and contents of the submissions reflects the diversity that is contemporary human geography. I hope that this forum enhances our appreciation of the points-of-view of others. Convergence towards a single widely accepted epistemological framework appears to be further away than ever.  相似文献

Passage of the Humphrey-Hawkins Full Employment and Balanced Growth Act of 1978 is the most recent step in the development of a national full employment policy. This article traces the origin of the legislative debate over full employment back to the 1940s, the only previous time that Congress gave serious consideration to full employment legislation. It analyzes the conflicting economic and political interests and philosophies that led to the defeat of the Full Employment Bill of 1945 and to passage of weaker legislation, the Employment Act of 1946, which dropped the commitment to full employment. The article then traces the contours of unemployment since World War II: recurrent recessions; significant unemployment between recessions; the unequal distribution of joblessness, hitting hardest at groups such as minorities, women, and youths; and growing urban and regional unemployment. Some of the hidden social, human and economic costs of unemployment are explored. So is the relationship between unemployment and crime, poverty, welfare, the urban crisis and inequality. Full employment reemerged as a major issue in the 1970s because of the impetus from groups whose unemployment problems persist between recessions. Coalitions of these groups pressed for a national policy to secure full employment for all groups. This led to passage of the Humphrey-Hawkins Act. But the controversy over full employment has not ended. Attempts to implement the Act, the article concludes, may heighten underlying controversies over issues such as inflation, wage, price and profit controls, the environment, and job creation and may make full employment one of the leading domestic issues of the 1980s.  相似文献

Excavations at Muweilah have uncovered twelve buildings encircled by two pairs of walls and ditches. We have published preliminary studies of several buildings. Research has now progressed to a stage where it is possible to produce a more complete analysis of the architecture. In this report, we present a detailed discussion of the fortifications and each building with its installations. Our assessment of the architecture identified the repeated combination of three rooms in many of the buildings in the Central Area of Muweilah. Moreover, a detailed study of the fortifications revealed several means of accessing Building II, the columned hall, in the Western Area. These findings offer insights into the organisation of Iron Age II settlements in south‐eastern Arabia.  相似文献

The aim of this paper was to develop a social sustainability tool to clarify what social sustainability means in land use planning processes. The tool was developed through a robust research process covering a large amount of scientific literature and built environment sustainability assessment tools. To assess how the developed tool works in practice, we used it as a coding system for the assessment of social sustainability in a case study from Finland. The case study includes the master planning process of a medium-sized city and the legal framework guiding it. The theoretical contribution of the paper lies in creating a holistic tool for the assessment of social sustainability in planning processes. This study also provides a strong practical contribution, as it goes beyond theoretical definitions to the pragmatic level by providing exemplary measures to be used in designing and implementing processes. Therefore, this paper is a valuable source for those stakeholders (for example planners, developers and policymakers), who struggle with the issue of the successful implementation of social sustainability practices, and it will help them to benchmark their processes against the themes found in the tool.  相似文献

This research investigates the plastic hinge length in lightly reinforced rectangular walls typically found in regions of low-to-moderate seismicity. Poor performance has been exhibited by lightly reinforced concrete walls in past earthquake events. A series of finite element analyses have been carried out which demonstrate that if the longitudinal reinforcement ratio in the wall is below a certain threshold value, there will not be sufficient reinforcement to cause secondary cracking, and instead fracture of the longitudinal reinforcement at a single crack could occur. A plastic hinge length equation has been derived based on the results from the numerical simulations.  相似文献
