马科斯独裁下的菲律宾土地改革(1972—1986)   总被引:1,自引:0,他引:1  
菲律宾农村土地分配的不公正状况在马科斯统治初期依然严峻,土地问题的急剧升级加剧了政体的演变,但军管法下的土改并没有使农民的生活状况得到明显改善。马科斯政府虽然与“旧寡头政治执政者们”逐步脱离,但和军人集团、政策制定者及商业权贵结合,实行“亲朋资本主义”政治,继续忽视农民的利益,农村基层组织也为地主势力所把持。制度创新的滞后严重阻碍了菲律宾农村土地改革和农村发展。  相似文献

This article presents a survey of Neolithic economy, land use, trade, natural environment, and usage of plant and animal resources in central Europe, 5415–2240 B.C. (4500–1800 bc). Early, Middle A and B and Late Neolithic materials are summarized and compared. The earliest farmers expanded from southern Hungary and adjacent areas into central Europe over a relatively short time period, 100–200 years. They occupied areas only with good soils; thus probably hunters and gatherers continued to exist in many regions of central Europe. There is an increase in population and more upland areas are exploited for farming during the Middle Neolithic A and B periods. By the Middle Neolithic B period, low-level hierarchical or ranked societies appear in some regions of central Europe. The Late Neolithic may represent a modification of the mixed farming strategy observed during the earlier periods. Perhaps the herding of domestic animals became more important.  相似文献

This paper is based on the 2018 Neil Smith Lecture presented at the University of St Andrews. It considers the plantation past/futures of Sapelo Island, Georgia, one of the Sea Islands forming an archipelago along the US Southeastern coast. I work through the abolitionist efforts of the Saltwater Geechee’s who have resided there since at least 1803 to better understand how we can mobilise an emancipatory politics of land and property and to produce commons that work to repair and heal the violence done through enslavement and ongoing displacement. I weave together a series of historical threads to better situate linked ideas of abolition democracy and abolition geography, and to extend the notion of abolition ecology as a strategic notion to connect Eurocentric based political ecologies with the emancipatory tradition of Black geographies.  相似文献

Knowledge about the Inca measurement system is based on information from the colonial chronicles and modern studies of the 16th-century Quechua dictionaries. Based on those texts, we can presume that the Incas used an anthropometric system of measurement adopted from the proportions of the human body. Using cosine quantogram analysis and statistical verification, it is possible to verify the existence of the measurement system used by the Inca architects. For this purpose, a measurement series of architectural and water infrastructure elements were collected from 3D point cloud of the Chachabamba and Machu Picchu settlements in Machupicchu National Archaeological Park.  相似文献

Developers seeking to assemble complementary parcels of land will likely encounter strategic behavior by landowners. Using a property‐level data set from Florida's Department of Transportation covering the period January 2000 to July 2014, I test whether bargaining delays lead to higher final transaction prices. Given the nature of the data, I can compare properties within the same roadway project to estimate the effect of delayed negotiations. My empirical estimates indicate that bargaining delays lead to increased final transaction prices. The magnitude of this effect is approximately 7 percent for the average holdout, however, the effect is nonlinear and diminishes over time.  相似文献

In this work, we apply a systemic approach to the analysis of a particular geographic territory, the industrial district. We are particularly interested in analysing the interaction between the productive-technological environment and the scientific environment by an examination of research contracts and patents. Our analysis shows that R&D activity in the Spanish ceramic tile District Innovation System was mainly conducted by suppliers. Final producers’ innovation efforts were related to non-technological aspects and differentiation.  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

A socially mixed population is a political ambition in Stockholm. By providing a mix of tenure alternatives throughout all neighbourhoods this objective could, at least partially, be fulfilled. Since current tenure proportions display a weak balance in many neighbourhoods it could be assumed that governing politicians – by primarily utilizing Stockholm’s vast landownership and municipal housing developers – attempt to bridge observed gaps. Distribution of new rental and ownership apartments in municipal land allocations should acknowledge the existing tenure composition in a neighbourhood. Methodically this article focuses on all (nearly 50,000) apartments channelled through Stockholm’s land allocation system between 2002 and 2012. After classification of all apartments based on tenure, location, year and developer (private or municipal) the information is merged with yearly housing stock characteristics for 128 neighbourhoods. The outcome is a unique data set allowing for statistical assessment of whether Stockholm’s tenure (and in extension social) mix ambition is reflected in practice. The present article aims to highlight the crucial importance of landownership in Swedish municipalities with an aspiration to achieve or maintain a balanced tenure mix. While the findings indicate Stockholm is complying fairly well with its ambition, the results do reveal some contradicting signs.  相似文献

New industrial innovation policies like smart specialization aim at boosting economic growth by diversification towards more complex and higher value economic activities. This paper proposes a conceptual and analytical framework to support the design and implementation of such policies considering place-specific preconditions, particularly the differentiation of the regional system of innovation and entrepreneurship and the degree of current industrial diversification. The paper expands on the links between these preconditions and the barriers and opportunities for industrial diversification. Consequently, it proposes an archetypical place-based policy framework covering overall policy objectives as well as measures at the level of actors, networks, and the institutional and organizational support structures.  相似文献

William Scott Owen figured prominently in Montgomeryshire history by being deeply involved with the lives of working people and active in local politics. He was an incomer from the south of England and a stalwart of the Anglican faith and the Tory party. He spent the whole of his working life in Montgomeryshire and came to be deeply respected in a part of Britain noted for its Nonconformity and Liberalism. Scott Owen was agent on the Gregynog Estate, which lies in the south east of the county, much of it now belonging to the University of Wales. This study of his life provides a vivid picture of the county in the late Victorian and Edwardian period and discusses why he became so well regarded.  相似文献
