ABSTRACT. Average monthly price data from twelve hinterland markets and the Houston port price for wheat are studied in a cointegration framework using the Engle-Granger "two-step" procedure and Johansen's maximum likelihood procedure. Out-of-sample forecasts from an error correction model are compared to those from a vector autoregression fit to levels and a univariate autoregression fit to first differences. This comparison suggests that modeling these (cointegrated) data as a levels vector autoregression, rather than as an error-correction process, results in significantly higher error bias, but lower error variance, at long horizons.  相似文献

The chronology of the period is briefly considered in the light of the dendrochronological results which have appeared in recent years. Patterns of settlement history in different parts of the area are then examined, and it is suggested that in some of them the late fourth millennium was a period of population decline which was not reversed until the Early Bronze Age, 1000 years later. Detailed information about specific local occupation patterns is provided by recent work on the circum-Alpine lake villages. Changes in cultural patterns during the period, especially the appearance of the Corded Ware, are discussed and explanations of them reviewed. It is argued that changing patterns of gender relations were a major feature of the period, linked to processes which eventually led to the development of small-scale chiefdoms. The development of copper and bronze metallurgy and its connection to these processes are discussed.  相似文献

Many timber finds lack some or all of the outer, sapwood rings formed in the years just before felling. In order to estimate felling date once the outermost remaining ring has been dated, it is necessary to estimate the number of sapwood rings originally present. Methods doing this for oak are reviewed in the light of an intensive study of living trees at one site and an extensive study of 175 samples from living trees in North Wales and northwest England. Some methods reported in the literature are found to be invalid. A method reported by Hollstein (1965) is most reliable, with modifications for known variations in sapwood number with position in the tree. At present the best available estimate is that a value of 30 sapwood rings be used (95% confidence limits: 19–50).  相似文献

ABSTRACT

This article reveals how the Cold War impinged upon not just national, but local political considerations and became woven into communal narratives. It contributes to the examination of religion in the conflict, adds to the historiography of Britain and the Cold War, and provides a context by which British Cold War experience and responses can be assessed. With Northern Ireland’s political similarities to Great Britain, its consistency with European norms and its overlaps with popular sentiment in the United States, Northern Ireland offers a gauge to better understand the nature of anti-Communism in the Cold War’s first decade and offers an unexplored perspective on the conflict.  相似文献

Abstract

This article introduces a special issue on the emergent relationship between the rhetoric and implementation of the rule of law concept in Southeast Asia. It thematically introduces four country case studies (Cambodia, Myanmar, Thailand and Vietnam), and the case of ASEAN’s adoption of the rule of law in region-building, which are included in this special issue. We highlight how ideals that are arguably central to the “tradition” of the rule of law are being excised, marginalised, defended and/or undermined in Southeast Asian contexts. We emphasise how the very concept is deeply contested and far from neutral – at stake is the very notion of “law” for whom, and for what. The article offers insight into the social dynamics affecting how the rule of law is being interpreted by political actors and how it is being contested and consolidated via governance practices in the region, and proposes new avenues for research in assessing how the rule of law is operating in transitional and authoritarian state settings.  相似文献

In debates over post‐capitalist politics, growing attention has been paid to the solidarity economy (SE), a framework that draws together diverse practices ranging from co‐ops to community gardens. Despite proponents’ commitment to inclusion, racial and class divides suffuse the SE movement. Using qualitative fieldwork and an original SE dataset, this article examines the geospatial composition of the SE within the segregated geography of Philadelphia. We find that though the SE as a whole is widely distributed across the city, it is, with the exception of community gardens, largely absent from poor neighborhoods of color. We also identify SE clusters in racially and economically diverse border areas rather than in predominantly affluent White neighborhoods. Such findings complicate claims about the SE's emancipatory potential and underscore the need for its realignment towards people of color and the poor. We conclude with examples of how the SE might more fully address racial injustice.  相似文献

The presence of single and also of married British women in overseas colonies, especially those employed by or married to men in the Colonial Service in the later colonial period, has been the subject of scholarly enquiry. Their lives, roles and values and their distinctive contribution, if any, to the development of empire and of its ending have been debated. Their gendered roles were usually subordinate in a masculine culture of empire, and especially as wives they are commonly regarded as marginalised. The archived records left by Lady Margaret Field reveal her commitment as a single woman to a colonial mission and her sense of achievement as a school teacher and educational administrator, while also acknowledging the independence and career satisfactions she subsequently lost when she married a senior Colonial Service officer who rose to be a governor. But it is also apparent that, though incorporated and subordinate as a governor's wife to her husband's career, she was not marginalised to a separate sphere. As is evident from this case study, governors’ wives had important and demanding political duties, and such responsibilities need to be acknowledged.  相似文献
