商末黄河中游气候环境的变化与社会变迁

新石器时代到商代黄河流域的气候属于温暖湿润期;商代后期气候出现厂干旱化,导致了古公亶父迁岐,文王迁程迁丰,帝乙帝辛时不断向南方发展;而商末的旱灾和饥荒是周武王克商的直接导火索,导致商周之际的改朝换代。商末气候环境的变迁对其时社会政治的影响极大。     

Current archaeological research in the Middle Atlantic region of the eastern united states

A major theme of current archaeological research in the Middle Atlantic region of Eastern North America is the recognition of cultural variability across space and through time. The most significant culture change experienced during the entire time frame of regional prehistory occurred ca. 5000 B.P., when there were major changes in regional environments. Before 5000 B.P., adaptations were characterized by small groups of mobile hunters and gatherers. After 5000 B.P., there were continued growth in regional populations and increases in sedentism, intensive use of a limited range of food resources, social group size, and social complexity.     

Doing Great Basin archaeology recently: Coping with variability

Great Basin archaeologists spent the 1970s and most of the 1980s tearing down the Desert Culture hypothesis without presenting compelling means for dealing with the empirical variability that made it untenable. Recent research seeks to understand this variability by examining the effect of key variables in extreme environmental contexts, especially in wetlands and at high altitudes, and by developing and refining models of optimality that anticipate variability as the local expression of general evolutionary ecological principles. Research on intraregional and ethnic variability has lagged behind—the former because it is said to be costly, the latter because it is problematical in theory.     

The micromammalian fauna from Border Cave,Kwazulu, South Africa

The micromammalian fauna from Border Cave is analysed in terms of community composition and structure. Changes in these aspects are interpreted as indicative of changes in vegetation and climate in the vicinity of the cave during the period of deposition. It would appear that vegetation comprised relatively extensive forest or thick bush and dense grass during wetter phases and fairly open savanna woodland, even open grassland, during drier periods. Variation through time in mean mandibular size in two species of Crocidura (musk shrew) was different both in the two species and from what was expected. It now seems likely that the size change constitutes a response to complex phenomena and not simply to changes in temperature. Comparison with the Boomplaas A sequence indicates that the same general pattern of change is reflected at both sites but that there was a greater amplitude of change at Boomplaas A and that ¹⁸O stage 4 was dry at this site but wet at Border Cave. Evidence for periodic changes in the distribution of various species, and in some cases the mutually exclusive occurrence of ecologically equivalent species, has implications for the zoogeography of the species involved. In particular, the occurrence of Pelomys fallax (creek rat) in the lower half of the sequence is of interest in view of its present distribution 600 + km north of Border Cave.     

部门管理人员感知的组织支持与组织氛围对旅游企业员工角色压力的影响

欧美学者普遍认为,角色压力是影响员工服务态度和服务行为的一个极为重要的因素,包括角色负担、角色冲突、角色模糊等3个组成成分.本文对我国11个地区的33个旅游企业进行了一次实证研究,检验部门管理人员感知的组织支持、企业的支持型领导氛围、授权氛围和员工服务行为评估氛围对员工角色模糊的影响.多层次线性模型分析结果表明,部门管理人员感知的组织支持会通过企业的支持型领导氛围,间接影响员工感知的角色模糊.企业的支持型领导氛围会通过企业的授权氛围,间接影响员工感知的角色模糊.此外,部门管理人员感知的企业支持还会调节员工感知的角色负担和角色冲突对他们的角色模糊的影响.     

The Green Economy Research Centre – positioning geographical research in Aberdeen to address the challenges of green economy transitions

ABSTRACT

The necessity to address climate change has resulted in a widespread debate about the need for a transition to a ‘greener’ economy. How such an economy emerges, by what drivers and at what scale is a significant source of speculation amongst the geographical research community. In the context of longstanding contributions to environmental geography from scholars working at Aberdeen University, this paper outlines a novel research agenda for the Green Economy Research Centre (GERC). The contours of the green economy are examined in the context of economic sectors of food production, tourism, energy and the blue economy. Cross-cutting themes of green transitions, governance, people and place and ecosystem services inform our academic contribution to this evolving and controversial societal issue.     

‘Culture’, ‘sustainable development’ and cultural policy: a contrarian view

Abstract

This essay offers a critical analysis of the ‘culture and sustainable development’ discourse, notably among cultural activists and in actually existing cultural policy. It interrogates the utility of the narrative, seeks to uncover the semantic manoeuvres it employs and challenges the conventional wisdom it represents. The essay first explores the itinerary of the ductile notion of ‘sustainability’, the ways in which it has been stretched far beyond the original intent of those who coined the term, and identifies the conceptual discontents that this semantic multiplication has entailed. It hypothesizes that precisely because the term ‘sustainable’ and its derivatives are so acceptable and malleable at the same time, they have been easy to yoke to the bandwagon of the many-faceted and totalizing process that is ‘development’, allowing many different actors to project their interests, hopes, and aspirations under this composite banner. The essay then analyses the campaign to make culture ‘the fourth pillar of sustainability’ under the banner of the movement called ‘Agenda 21 for Culture’. It concludes with a plea for a return to the original ecological focus of the term ‘sustainability’ – notably as regards climate change – and outlines some cultural policy responses such a focus can and should generate.
