广西玉林市博物馆馆藏七件铜鼓的初步分析研究

迄今已有2 700多年历史的铜鼓,是南方少数民族地区节日、喜庆、兵事、婚丧、祭祀、礼乐等场合使用的一种重器。为了对锈蚀状况做出科学的现状评估,为器物保护修复技术路线的制定和修复工作的开展提供科学指导,对玉林市博物馆馆藏7件铜鼓综合运用了体视显微镜、金相显微镜、激光显微拉曼光谱仪(RS)和环境扫描电镜及能谱仪(ESEM-EDAX)等仪器进行了金相组织和合金成分分析以及锈蚀产物的分析。分析结果显示:7件器物皆为泥范铸造成型,未见热、冷加工处理现象。7件铜鼓皆为铅锡青铜合金,总体呈低锡高铅的特点。组织形态呈典型α固溶体树枝晶偏析,锡含量处于6.0%～12.2%,分布较为集中,处于中等含量水平(5%≤Sn15%);铅含量处于14.4%～28.2%,铅含量普遍较高且分布较为集中,处于中高铅(10%≤Pb15%)和高铅含量(Pb≥15%)水平,合金中高铅含量配比应为工匠有意合金配比选择;铜鼓的腐蚀类型为α固溶体富铜相优先腐蚀,保存环境主要是富氧、少氯,铜鼓表面锈蚀产物主要为绿色孔雀石和蓝色蓝铜矿以及氧化物,有少量白色白铅矿。在保护修复工作中对于这些无害锈可保留,不予处理,并注重防氧。对于铜鼓表面夹杂泥土,需进行清洗去除。研究结果可为器物保护修复技术路线的制定和修复工作的开展提供科学指导。     

TEMPORAL and SPATIAL VARIABILITY OF CANADIAN INVENTIVE COMPANIES and THEIR INVENTIONS: AN ISSUE OF OWNERSHIP

Inventing is an important prerequisite for industrial economies to remain technologically competitive. Yet it is not well known how inventive companies of domestic or foreign ownership can affect a nation's technological base and, ultimately, its spatial-economic system. The present study examines this relationship in Canada by investigating the performance of its indigenous and foreign-owned inventive companies at the national, subnational, and urban levels. The results indicate that: (1) Canada's indigenous inventive companies are distinct from their foreign-owned counterparts in that they are generally smaller, are more apt to have teams of inventors, are more likely to develop product inventions, have come to manage a greater share of this nation's inventions, and are increasing their role in key Canadian industries; and (2) geographically, Canada's two largest cities and its core region were adversely affected by the declining inventiveness of American-controlled companies during the 1980s. L'esprit ?invention est une nécessité pour que les économies industrielles restent en conditions de concurrence technologique. Cependant, on connaît très peu de la manière que les entreprises inventives de propriété domestique ou étrangère affectent la base technologique ?un pays et, enfin, affectent son système spatio-écono-mique. La présente étude considère ces rapports au Canada au niveau national, sous-national et local, en exminant les performances des entreprises inventives indigènes et étrangères. Les résultats indiquent (1) qu'au Canada les entreprises indigènes et inventives diffèrent de leurs analogues étrangers: en général elles sont plus petites, ont plus tendance à consister en équipes ?inven-teurs, sont plus susceptibles de développer les inventions produites, produisent une plus grande part des inventions canadiennes, et sont en train ?augmenter leur rôle dans les industries canadiennes; et (2) que le déclin de ?esprit ?invention dans les entreprises dirigées par les américains a affecté défavorablement les deux villes les plus grandes au Canada, ainsi que la partie centrale du pays, pendant les années 1980.

Sensory Stress and Personal Agency: Emotional Casualty Rates amongst USAAF Heavy Bomber Crews over Europe during the Second World War

The findings of psychiatrists working for the USAAF have long dominated scholarship on aerial combat stress during the Second World War, including explanations why the emotional casualty rate aboard American heavy bombers varied by crew position. Critical examination suggests that the answers put forward are unsatisfactory, opening the way for an alternate analytic approach. Comprehending the different forms and levels of sensory stress heavy bomber crews experienced during combat missions in combination with different degrees of individual agency yields a more nuanced and convincing way of comprehending why some jobs were more psychologically demanding than others, and hence why casualty rates varied.     

Defining dreams: young mothers’ agency in constructions of space

Understanding young mothers’ emic, or insiders’, spatial experiences is critical to realizing how their agency manifests in constructing and producing spaces, as opposed to common images of them as passive, vulnerable women living in deprived neighbourhoods. Set in the shrinking region of Parkstad Limburg in the Netherlands, this article draws on in-depth interviews and long-term participant observation in order to explore which modalities of agency emerge from young mothers’ spatial engagements with their neighbourhoods and homes. This article contributes to greater diversity and more agentic representations of young mothers than commonly perceived, and to a nuanced understanding of agency. The findings reveal that these women are continually navigating the social, physical and economic–political dimensions of space, from which four modalities of agency emerge: (1) ‘adhering to norms’, (2) ‘defining dreams’, (3) ‘challenging rules’ and (4) ‘considering options’. Contrary to understandings within a dominant independence-oriented discourse of agency as taking subversive action, this article shows that agency occurs in tacit, routine spatial practices, whilst navigating through individual circumstances and sociospatial structures and norms.     

Growing up in a tourist destination: negotiating space,identity and belonging

There is little research on children’s experiences of growing up in a popular tourist destination, where place and space are contested with visitors, migrants and temporary residents. Existing literature on young people’s experiences of their socio-spatial surroundings has focused predominantly on the rural/urban dichotomy, often neglecting to explore how identity and belonging are negotiated in complex community contexts such as tourist destinations. This paper reports on recent research that suggests that young people’s experiences of growing up in such an environment are nuanced and diverse, with their rich narratives disrupting socially constructed distinctions between the rural and the urban, merging experiences from both worlds.     

Sunflowers,youthful protestors and political achievements: lessons from Taiwan

ABSTRACT

In 2014, an interesting youth movement collective started small p political and big P Political action and resistance in Taiwan. Their protest was against the way a major trade agreement proposed between China and Taiwan was being non-democratically pushed through the Taiwanese legislature. In this article, we provide an analysis of the activities of the Sunflower Student Movement (SSM) as a means to record a relatively little-known youthful and youth-centric successful uprising. It serves to place the SSM, and other East Asian-based protests, on the map of young people’s political geographies, and explores the paradoxical political and spatial practices pursued by young Taiwanese. This case study makes visible the interconnectedness of big P/small p politics of everyday youth geographies within an Asian context.     

Who we are at work: millennial women,everyday inequalities and insecure work

Based on research with millennial women in Canada, this article examines the process of workplace identity, or (un)conscious strategies of identity management that young women employ at work. First, despite increasing labour market participation from women, young women’s experience of the workplace can be one of precarity and insecurity. Many millennial women have responded with a ‘positive front’ – saying yes to all work tasks while highlighting their likability and acceptance of the status quo. This is not seen as a permanent strategy, but rather one that gets you into the workplace and ‘liked’ until your work speaks for itself. Second, and operating at the same time, young women also use tactics to confront intersections of ageism/sexism in the workplace. While some employ conscious strategies to be ‘taken seriously’ through dress, small talk, even taking on stereotypical traits of masculinity to be recognized as competent, others explicitly confront inequality through ‘girlie feminism’ with a pro-femininity work identity that challenges the masculine-coded norms of how a successful workplace operates and what it looks like. In jobs of all types, who we are at work is a constantly shifting negotiation between how we are treated and seen by others, the workplace as a social space, our past experiences and our own expectations. Considering young women’s work identities reveals how power and privilege operate in the workplace, and the possibilities of young women’s agential challenges to inequitable workplace norms and a precarious labour market.     

Ruling the Land of the Yellow Lama: Religion,Muli, and geopolitics in the 17th century Sino-Tibetan borderland

Abstract

The author scrutinizes the history of Muli (木里) as a semiautonomous political entity in the 17th century southern Sino-Tibetan borderland. By tracing Muli’s improvization in the face of multiple powerful regimes such as the Naxi kingdom, the Geluk Tibetans, the Khoshut Mongols, and the Chinese dynasties, the author explores how an indigenous notion of power took shape in the wake of geopolitical turbulence. Before 1580, Muli was a colony of the Naxi kingdom and dominated by the Kagyu school of Tibetan Buddhism. After 1640, it became a stronghold of the Tibetan Buddhist Geluk school and was deeply involved in the power struggles between the Geluk and Kakyu schools as well as the Tibetans and Mongols. Despite of acknowledging multiple sovereigns, Muli rulers utilized various tactics to hold on to power and prioritize local interest. The nuanced, yet creative, strategies Muli people adopted showcases the significant role border regimes played and their agency in shaping the power dynamics in pre-modern Eastern Asian borderlands.
