This study examines perceptions of the environment in farming communities in the forest ecotone of Ghana. It places local knowledge within a socio-economic and historical context and argues that knowledge is continually evolving, attempting to solve existing problems and discovering new ones. It maintains that favourable conditions exist in farming communities for environmental actions and development approaches based on sustainable development, since these areas have suffered from the negative effects of degradation. However, major constraints exist within the wider political economy and policy framework, which is still locked into environmentally-hostile export-oriented production, and political models which marginalize rural people.  相似文献

Roger Cooter is concerned about the survival of historiography under the pressures of neoliberal economics and the entertainment industry. His and Claudia Stein's book is a welcome call for “critical history,” which is aware of own fundamental intellectual categories. Cooter emphasizes the importance of self‐reflection and political contextualization of all knowledge‐production. However, although reflection is undoubtedly a virtue, it is not clear whether historiography is under such a severe threat. It is also necessary to ask where the limits of contextualization lie. It is doubtful whether a fully localized and contextualized study removed of all “presentist” categories and language is possible. In addition, one should avoid combining antirealism about natural sciences in the name of anti‐Whiggism with realism about historical knowledge in attempts to provide contextualized accounts of the past. What is needed above all is the hermeneutical dialogue between the language of past agents and the language of present actors.  相似文献

Abstract

The Early Metal Period (1800 cal BC–AD 300) of the Finnish inland regions is characterized by a scarcity of archaeological remains. Its latest stages, in particular, have proved to be difficult to interpret. This paper discusses the continuity of settlement in the Early Metal Period as indicated by archaeological survey and pollen-analytical data. The study area is situated in Repovesi National Park in southeastern Finland. The pollen analysis was constructed from a sediment sequence taken from Lake Katajajärvi. The archaeological survey data from Repovesi National Park supports earlier hypotheses of the small number of Early Metal Period sites. In the pollen data, the first anthropogenic impact is recorded from about 2600 BC onwards, with weak signs of cultivation around 2370 BC. From around 1900 BC onwards a clear change in tree, shrub and herb pollen percentages indicates anthropogenic impact, possibly grazing, in the area. The pollen-analytical results also revealed a cultivation period of about 900 years at the end of the Early Metal Period, providing proof of continuity in settlement during a period characterized by a scarcity of archaeological material. A new beginning of cultivation from cal AD 1160 to 1250 onwards can be considered as indicating population growth, developing settlements and the colonization of new areas. The results from Repovesi are challenging from an archaeological point of view, because they represent slash-and-burn cultivation that appears to have been practised in total wilderness conditions. Comparison of the Lake Katajajärvi results with other areas raises new questions that call for a discussion of early slash-and-burn cultivation in new perspective.  相似文献

The westward migration of the Ojibwa Indians from the Sault Ste. Marie area of northern Michigan beginning about 1650, resulted in their widespread dispersal. Those who settled in the coniferous- mixed forest zone of interior Wisconsin and Minnesota adapted to the local conditions by developing an “emphatic” hunting economy, gaining a large share of sustenance from hunting large game and furred animals. On the other hand, the Ojibwa who settled along the southern littoral of Lake Superior are said to have engaged in fishing for their primary subsistence. The latter proposition is reinforced in the narratives written by Euro-American visitors to Lake Superior in the early 19th century. This study evaluates this alleged reliance on fish, and points to contradictions and inconsistencies in the narratives in the context of the Fond du Lac band located at the southwestern extremity of Lake Superior.  相似文献

The article considers the story of the Norwegian sports strike during the Second World War. What kind of resistance does the story reveal? What was the effect of a boycott of leisure activities like sports? The Norwegian sports organizations, unlike other international sports organizations, came to see themselves as part of the resistance movement against the Nazi regime during the German occupation from 1940 to 1945, using non-violent, civil disobedience as their weapon. Unprecedented historically and internationally, this meant that Norwegian sportsmen and women, for four and a half years, stopped participating in any way in sport. The boycott comprised sportsmen and spectators, regardless of whether the contestants were friends or foes, Allies or Nazis, Norwegians or German. Based upon previous and recent research the article contends that the sports strike can be considered an effective act of civil disobedience. It demonstrated in a visible way that civil resistance was possible, while the German and Nazi authorities sought to promote sports as a means of creating an impression of normality. Finally, the story of the sports strike can be read as a tale of the limitations of totalitarian regimes.  相似文献

The development of agriculture is closely associated with the domestication of wheat, one of the earliest crop species. During domestication key genes underlying traits important to Neolithic agriculture were targeted by selection. One gene believed to be such a domestication gene is NAM-B1, affecting both nutritional quality and yield but with opposite effects. A null mutation, first arisen in emmer wheat, decreases the nutritional quality but delays maturity and increases grain size; previously the ancestral allele was believed lost during the domestication of durum and bread wheat by indirect selection for larger grain. By genotyping 63 historical seed samples originating from the 1862 International Exhibition in London, we found that the ancestral allele was present in two spelt wheat and two bread wheat cultivars widely cultivated at the time. This suggests that fixation of the mutated allele of NAM-B1 in bread wheat, if at all, occurred during modern crop improvement rather than during domestication. We also discuss the value of using archaeological and historical plant material to further the understanding of the development of agriculture.  相似文献

The Oulu region in Northern Finland has witnessed a remarkable growth of ICT industries since the 1980s. A town near the Arctic Circle with only 140,000 people (2012) created a high-tech business that employed at its best nearly 16,000 people in the region at the millennium. This article investigates the historical background of this phenomenon, which is not so much an imitation of Silicon Valley, but rather a result of special Finnish and northern characteristics. The most important contributing factors were the University of Oulu, governmental support and the success of the Nokia Corporation. Oulu's strength was the early clustering of the focal actors. Oulu established the first Technology Park in the Nordic countries in 1982. The northern mental environment, Oulu's traditions and many exceptionally active persons also contributed to the phenomenon. The case of Oulu is presented in a larger international context with the help of studies on regional high-tech clusters and the development of the information society. Present and future challenges are also addressed.  相似文献

The contemporary trend within natural resource governance sees a strong increase in collaborative management. A successful turnout of these arrangements is, however, dependent upon the formation and characteristics of advocacy coalitions. Uncovering the rationale determining coalitions is therefore a key undertaking in policy analysis and the advocacy coalition framework (ACF) has been widely applied for this purpose. This article aspires to test several important hypotheses regarding the nature of coordination networks and the formation of coalitions, treating the ACF both as an inspiration and as a framework in need of further refinement. This is done in the context of a complex and conflict‐ridden policy subsystem: the Swedish carnivore‐management subsystem. The results indicate, firstly, that perceived belief correspondence, and not perceived influence, is the driving mechanism behind coordination; and, secondly, that the catalog of beliefs shared by actors within a coalition is composed by policy core beliefs, in particular, with a more normative content, while no connection between deep core beliefs and coordination is found.  相似文献
