Differences in labour force participation and unemployment rates between indigenous populations and immigrants are common throughout Europe, but the gap seems to be particularly wide in Sweden. Based on studies of workplaces that traditionally employed large numbers of immigrants, but where they are now declining, it is argued that a driving force behind this process of exclusion is to be found in technological and organisational changes. These changes seem to be more pervasive in the Swedish labour market than in other economies in Europe. What is sometimes called the ‘Swedish model of working life’ has turned into the systemic exclusion of immigrant labour.  相似文献

Recently, the Maya site of Nakum has been the subject of intensive research by the Institute of Archaeology of the Jagiellonian University, Kraków, Poland. This work has significantly enriched our knowledge of the ancient Maya of northeastern Guatemala, especially during the so-called Terminal Preclassic or Protoclassic period (ca. 100 b.c.a.d. 300), when many Maya centers suffered decline. The Protoclassic covers the transitional moment between two important periods of Maya chronology, the Preclassic and Classic, but so far, the typical ceramic components of this phase have been found in only a handful of Maya sites. Our research indicates that Nakum underwent important building programs and stable cultural growth during the discussed period. Here we discuss evidence of architectural and cultural activity at Nakum during the Terminal Preclassic within a wider geographic context. Our research highlights the role that Nakum played within Maya geopolitics in northeastern Guatemala and also contributes to the understanding of socio-cultural processes that the Maya civilization was undergoing during the as-yet poorly understood Protoclassic period.  相似文献

Studies of the Mesolithic–Neolithic transition in Europe have focused on plants and animals exploited for food. However, the exploitation of plants for fibres underwent a significant change with the addition of domestic flax as a fibre crop. While the technology of flax fibre processing is increasingly understood by archaeologists, its material value as a fibre crop in comparison to indigenous fibre is less well explored. We examine the mechanical properties of flax and two indigenous fibres (lime bast, willow bast), by testing fibre strips for tensile properties and discuss the results in the light of material choices in these periods.  相似文献

Pérez, D.E., Alvarez, M.J. & Santelli, M.B., July 2016. Reassessment of Neovenericor Rossi de García, Levy & Franchi, 1980 (Bivalvia: Carditidae) using a geometric morphometric approach, and revision of planicostate carditids from Argentina. Alcheringa 41, xxx–xxx. ISSN0311-5518.

Various systematic approaches have been applied to the Neogene planicostate carditids of Patagonia. Some authors have included these species within Venericor (known from the Eocene of North America and Europe) or in Megacardita (recorded from the Miocene of Europe). By contrast, Rossi de García et al. erected the endemic Neovenericor in 1980 for Patagonian species. The three proposed genera have variable outlines and similar hinge teeth configuration. Two geometric morphometric analyses were performed, which included the type species of the following taxa: M. jouanneti (middle Miocene, Mediterranean Basin), V. planicosta (middle Eocene, Paris Basin) and N. austroplata (early Miocene, Chenque Formation, Chubut Province). In the first approach, an Elliptic Fourier Analysis was used to test the general variability of outlines. In the second, a landmark-based method was employed to analyse the hinge configuration, followed by a Discriminant Function Analysis. The outline analysis discriminated Megacardita from the other two taxa based on its more elongate and rectangular shells. The Landmark Analysis distinguished the three taxa based on both, left and right hinges. The Discriminant Function Analysis showed significant values for this differentiation. Neovenericor has a higher hinge plate, broader and less posteriorly inclined teeth, and a less sinuous ventral edge than Megacardita; and it has larger and more posteriorly inclined teeth than Venericor. Other morphological characters of the genus include an intermediate number of radial ribs that do not dissipate ventrally, and wide and deep intercostal spaces. Thus, Neovenericor is clearly a distinct taxon. All Argentinian planicostate carditids were revised and included in this genus because they embrace its diagnostic features.

The aborted 1967 attempt of the dictatorship to transform itself into some form of democracy has generally been under-researched, and even more so with regard to its international implications. And yet, the issue of foreign influences on the “Markezinis Experiment” has been given excessive weight – first and foremost by the protagonist himself, who blamed his failure and downfall on negative American interference – namely on the then US Secretary of State Henry Kissinger’s adversarial stance. Based on the examination of the international context in three main frameworks – namely its relations with the United States, Europe and the Cyprus issue – this article seeks to give an answer to the question of the foreign factor’s impact on the failure of the “experiment”.  相似文献

This paper seeks to make a contribution to on-going debates about how to conceptualise the spatial processes of renewable energy transition. It makes a case for understanding renewable energy transitions as simultaneously spatial and political processes, constitutive of new territories and configuring development pathways. Drawing on a case study of South Africa's Renewable Energy Independent Power Procurement Programme (REI4P), the paper explores the ways in which energy transitions are intrinsically bound up with both the materiality and the historical and contemporary politics of land. It then examines the relationship between energy transitions and territory to conceptualise the ways in which transitions take on an experimental shape in the form of 'zones'. The paper argues that these zones are new territories deploying forms of spatial and political-administrative exceptionality, which allow political and economic actors to exercise authority and commercial power. Two types of zone emerging from South Africa's energy transition exemplify these processes: legally-defined zones for the development of solar and wind energy and zones of socioeconomic development required by REI4P. The paper explores the spatial and political consequences of these strategies and suggests that these may not necessarily translate into conflict and confrontation, but instead produce uneasy co-existences of different political, social and spatial projects and interests, with potential to create new polities.  相似文献

Today, there should be little doubt that new reproductive technologies have ‘diversified, globalized, and denaturalized’ human reproduction (Inhorn and Birenbaum-Carmeli 2008). Not only have assisted reproductive technologies developed and spread throughout the world at a rapid pace, but this significant development has also given rise to a global market of cross-border reproductive care (CBRC). This article seeks to investigate CBRC between Sweden and the Baltic states, in which Swedish infertility patients travel to private fertility clinics as recipients of egg donation. This article argues that the restructuring of the European space (occurring in and through both the so-called ‘transition’ of the former Eastern Bloc and the expansion of the European Union) constitutes crucial conditions of emergence for the trans-European market of infertility care, which not only results in new modalities of reproductive mobility but also articulates a new set of interrelated European gendered reproductive subjectivities. Particular attention will be paid to the ways in which such ‘new reproductive subjectivities’ – here exemplified by a sample of cross-border donor egg recipients – are articulated in relation to notions of ‘choice’ and what I call ‘biodesirability’, and how such notions cannot be exempt from its specific post-socialist European context.  相似文献

This paper presents new AMS radiocarbon dating results of six ungulate bones from the current excavation of Isturitz Cave, France, layer C 4c4. The assemblage from this layer exhibits a suite of traits closely aligned with the Early Aurignacian, but with some aspects that bear strong similarities with the Protoaurignacian, with possible in situ technological transformation. Accurate and precise dating of the late Middle Palaeolithic and the early Upper Palaeolithic periods is critical to our understanding of the possible relationship between final Neanderthals and early modern humans in Europe. As such, a rigorous set of sample selection and evaluation protocols was developed and used in this research. Among these, only cutmarked bones were selected and a total of 31 targets were made, giving a weighted average of 37,180 ± 420 BP for this assemblage and providing a terminus ante quem for the ornaments, decorated artefact and amber pendants beneath it. The implications and importance of these results to debates concerning the chronological relationship between the Châtelperronian, Protoaurignacian and Early Aurignacian and associated debates regarding hominin dispersal, interaction and the timing of technical and cultural innovations are discussed.  相似文献

治所作为行政区域的核心,其设置或迁徙过程中所考虑的问题和由此反映的政治理念,无疑也是当时行政区划建设思想的体现和重要组成部分。有关历史上政区治所迁徙的研究比较薄弱,对于清代政区治所迁徙到目前尚无人作全面深入的研究。本文通过详细探究有清一代的省会、府、厅、州、县等主要政区治所的迁徙及其发生原因,来研究清朝行政机构治所设置的指导思想和规律,总结治所迁徙的各种具体原因。  相似文献

Rates of type 2 diabetes and other metabolic disorders are elevated among Indigenous peoples; however, no research has examined the origins of these diseases among the Métis. This case study documents a transition in lifestyle and health that affected the Keg River Métis of northern Alberta during the middle decades of the 20th century. This community began to experience previously absent diseases, including obesity, heart disease, gestational and type 2 diabetes, and preeclampsia. This shift in disease burden appears tied to rapid socio‐cultural and economic change driven by a decline of traditional economic activities, access to government transfer payments and wage labour, an increasingly sedentary lifestyle, and a growing availability of non‐traditional foods. This study points to earlier emergence of diabetes among Canadian Indigenous populations than commonly credited and presents the case for a rapidly evolving epidemic tied to environmental and cultural change. Underlying this were structural changes that emerged out of colonization.  相似文献
