Eastern North America in late Pleistocene times was characterized by two major environmental regions: a periglacial tundra or open spruce parkland and an extensive complex boreal/deciduous forest in the unglaciated, lower latitudes. These environments selected for different adaptive strategies on the part of human foraging groups—known archaeologically as Paleoindians. Those in the tundra and tundra-forest region were highly mobile, possibly specialized hunters, exploiting caribou; those in the forest were generalists, exploiting a variety of subsistence resources with a less mobile settlement system. There is little evidence in either area for hunting of Pleistocene megafauna. These differences in adaptive strategies are reflected in the record of sites and isolated fluted points scattered throughout the region, as well as aspects of tool technology, function, and patterns of stone use.  相似文献

ABSTRACT

This paper discusses the role of smart specialization in catalyzing the development of early-stage regional innovation systems in less advanced regions, either by facilitating the emergence of some defining elements that were lacking or accelerating the development of others, such as: a regional knowledge base and a dynamic learning process, institutional structures, network integration mechanisms among key innovation actors, regional industrial specializations, and collective identities. The paper exemplifies this process with the case of Romania, a country where the research and innovation system is centralized at national level and regional innovation systems are in the early days. The transformations taking place in the Romanian regions within the process of implementing smart specialization, assisted by the European Commission's Joint Research Centre in the project “Targeted Support to Smart Specialization in Romania”, suggest a dynamic coagulation of institutional, financial, policy, and human factors that catalyzed the development of regional innovation systems in the country and introduced a novel approach to innovation policy.  相似文献

This study offers a new framework for understanding the decision-making strategies of first-time voters. Using data from in-depth interviews with young people prior to the 2013 Australian federal election, the paper explores the extent to which our participants were knowledgeable about the upcoming election and the degree to which they invested cognitive effort into making their voting choice. The analysis reveals five distinct voting strategy typologies, which we use to construct a conceptual model that identifies and describes different voting approaches employed by young people. The findings show that young people are not a homogenous group of disinterested and disengaged voters. Instead, within a population of young citizens there are varying levels of interest and effort being invested into electoral participation.  相似文献

ABSTRACT

Interdisciplinary literary and historical studies of late Qing vernacular are rare, and the vernacular texts of the Sichuan Railway Protection Movement have been overlooked by academics. This paper focuses on this topic, arguing that the discursive strategies in such texts revolved around the movement's aim of “breaking the agreement and protecting the railway,” and primarily included discourses on constitutionalism, financial interests, patriotism, cultural order, and the late emperor, as well the ideas of “ridding the emperor of evil ministers,” borrowed from traditional Chinese political discourses, and “national subjugation,” within the context of the national crisis. None of these discourses were “anti-Manchu” or “revolutionary,” yet they were able to mobilize the people of Sichuan to devote themselves to the Railway Protection Movement, as well as attracting the “sympathetic understanding” of high-ranking Sichuan officials, such as Wang Renwen 王人文 and Zhao Erfeng 赵尔丰, thus lending discursive power to the railway protection camp in its game of political chess with the Qing court. Meanwhile, the government's weak discursive power was an important factor in the overthrow of the Qing Dynasty by the revolutionary tide triggered by the Sichuan Railway Protection Movement. The discursive strategies in vernacular texts on railway protection (including the particularly strategic discourse on the late emperor) spread, transformed, and were reborn to varying degrees over the course of history.  相似文献

While the field of migration studies is expanding to understand the nuanced experiences of women across Asia, there has been little discussion of how these studies were conducted. This article draws on the reflective accounts of three researchers on a team project investigating the lived experiences of female Bangladeshi migrant workers in Malaysia. While the research aims centred on understanding the lives of the Bangladeshi migrant women, the team spent a significant amount of time negotiating male gatekeeper violence in the field. The article further describes the researchers’ experiences of sexual harassment and intimidation, and explores these through the complex locations of the migrant workers and the female researchers in the field site. In addition, the article deals with the way in which the team’s feminist research sensibilities were challenged in the context of negotiating that violence. The ethical dilemma of continuing the research in the face of persistent violence was dealt with by discussing approaches employed in managing the violence. Analysing male gatekeeper violence in the field, allowed for conversations around the intersection of migration and masculinities. This auto-ethnography reveals methodological concerns for female researchers and exposes the negotiated nature of the front line of migration research.  相似文献

Level IV of Molodova I, an open-air Middle Paleolithic site in the Ukraine has been described by some researchers as a possible source of evidence for early symbolic behavior. We examined bone objects from this layer that were identified by Ukrainian researchers as exhibiting possible Neandertal produced engravings including two anthropomorphic figures. While we have determined that there is no evidence of symbolic activity at Molodova I, the database we have created, with its systematic recording of traces left by taphonomic agents on faunal remains, provides a better understanding of the overall site taphonomy.  相似文献

The recent discussion regarding contemporary urban regeneration has underlined the increasing role of art and cultural agglomeration as an essential part of a progressive agenda for local development. In fact, there is a good deal of literature which is related to specific and finite cultural strategies. Although scholars, in some cases, may suggest other perspectives, their value narrows to a comprehensive evaluation regarding the possible interpretation of cultural agglomeration in respect of urban regeneration. Accordingly, this study, by using an interdisciplinary systemic approach based on the clustering of cultural carriers, developed the cultural strategies under a six concepts scheme. The study then, through developing a method based on modes and development approach of cultural agglomeration, recategorized the six mentioned strategies into three major categories of cultural strategies, to find out their contribution in the process of urban regeneration. Overall, the study revealed the extent of cultural agglomeration as a method of developing cultural strategies in urban regeneration.  相似文献

The organizational culture elite is studied as a new elite group emerging within a stable neo-corporatist state. Does this new elite adopt existing modes of operation or place itself at bay from the more established elite groups? The emergence of and changes in the culture elite are discussed from a historical perspective in terms of social background, recruitment processes, occupational careers, gender composition, political outlooks, lobbying, and media strategies. The culture elite is systematically compared to two other elites: the university elite, the most similar among the elites, and the economic elite, assumedly representing the greatest contrast. Despite special characteristics in the social situations and political views of the culture elite, it is concluded that the mode of operation of this group indicates a high degree of adaptability to the general system of elites. A main reason is assumed to be the integrative power and liberal quality of the state in a neo-corporatist regime.  相似文献

The high Andes of western South America feature extreme ecological conditions that impose important physiological constraints on humans including high-elevation hypoxia and cold stress. This leads to questions regarding how these environments were colonized by the first waves of humans that reached them during the late Pleistocene. Based on previous research, and aided by human behavioral ecology principles, we assess hunter-gatherer behavioral strategies in the Andean highlands during the late Pleistocene and early Holocene. Specifically, we formulate three mobility strategies and their archaeological expectations and test these using technological and subsistence evidence from the six earliest well-dated highland sites in northern Chile. Our results suggest that all of the studied sites were temporarily occupied for hunting, processing animals, and toolkit maintenance. The sites also exhibit shared technological features within a curatorial strategy albeit with different occupation intensities. From this evidence, we infer that the initial occupations of the highlands were logistical and probably facilitated by increased local resource availability during a period of environmental amelioration.  相似文献
