史前漆膜的分析鉴定技术研究

研究了漆膜分析的三种主要方法：裂解质谱,红外光谱,裂解色谱。通过大量实验比较了各种方法的适应性和可靠性,建立了以裂解色谱／富里叶红外光谱联用技术来鉴定漆膜,并对影响裂解反应的因素及色借条件进行了深入的研究,获得了可以重复,具有特征性的漆膜高分辨裂解色谱图,同时对裂解色谱图中主要组分作了定性鉴定,提高了裂解色谱法分析漆膜的可靠性。该方法具有灵敏度高,样品用量小,共存杂质影响小,操作简便等优点。应用核分析技术对河姆渡,良诸庙前遗址出土的二件红色涂料样品进行了鉴定。分析结果证实了河姆渡出土的红色涂料木碗上的涂料是我国至今发现的最早的生漆漆膜。     

汉代漆器的剖析

The weight of nineteenth century Mexicans in the Western United States

When traditional methods for measuring economic welfare are scarce or unreliable, heights and BMIs are now well-accepted measurements that represent biological conditions during economic development. Weight, after controlling for height, is an additional measure for current net nutrition. Little is known about how weights varied among Mexicans living in the nineteenth century American West. Between 1870 and 1920, average Mexican weight was low and remained constant. Mexican farmers had the heaviest weights, and unskilled worker weights were low. Weight of Mexican-born individuals were higher than Mexicans born in the United States at low weights but lower at high weights. For combined characteristics, weight varied the most with age, an uncontrollable characteristic, indicating that nineteenth century Mexican current net nutrition varied the most with factors over which they had no control.     

Appeasing the Spirits Along the ‘Highway of Horror’: Civic Life in Wartime Republic of Vietnam

During the Easter Offensive hundreds of Republic of Vietnam soldiers and civilians were killed while fleeing Qu?ng Tr? city along Highway One, earning this stretch of the road the name ‘the Highway of Horrors’ [??i L? Kinh Hoàng]. This article examines this understudied event and the efforts of ordinary people, particularly the staff of the daily newspaper Sóng Th?n, to collect and bury the corpses left on the highway. In focusing on this humanitarian endeavour, it highlights the spiritual consequences of mass death, people’s agency in countering the violence of the Vietnam War, and the dynamism of South Vietnam’s civil society.     

Gabrielle Lévy and the Roussy-Lévy syndrome

In 1934, Gabrielle Lévy died at the age of 48. She became well known for an article she published on a hereditary polyneuropathy in cooperation with Gustav Roussy, resulting in the eponym Roussy-Lévy syndrome. Not much is known about this extraordinary neurologist/neuropathologist. Her family declared that she died from the disease she was studying. She was a pupil of Pierre Marie, with whom she worked at the Salpêtrière in Paris and wrote on war neurology. In cooperation with Marie, she published a number of articles on postencephalitic syndromes, which also became the subject of her 1922 thesis. Three years later, she became associate physician at the Paul-Brousse Hospital in Paris, where the study of brain tumors became one of the subjects of her scientific work. Remarkably, Lévy was first author in a few of her many articles, although Roussy confirmed that she often initiated the study and even wrote the main part. In this article her career is considered in the context of the struggle of women physicians to improve their position during the early-twentieth century. She probably died from a brain tumor or a postencephalitic syndrome.     

Valentin Magnan and Sergey Korsakov: French and Russian pioneers in the study of alcohol abuse

This study focuses on two outstanding psychiatrists: the Frenchman Valentin Magnan (1835–1916) and the Russian Sergey Korsakov (1854–1900). Their international renown is primarily associated with their investigations into health consequences of alcohol consumption; they were pioneers in this field, and happened to know each other well. The similarities and differences are shown in social and scientific approaches adopted by these two scientists. In his work, Magnan focused mainly on absinthe and epilepsy; he considered alcoholism to be a hereditary mental disorder. Korsakov, after a period of work in Paris under Magnan’s guidance, represented a more modern generation and was advancing fundamental ideas on the nature of psychoses and merging clinical features, somatic, psychological, and social factors. Although Magnan has practically disappeared from the current literature on alcoholism, Korsakov is still clearly present today.     

Border blocking effects in collaborative firm innovation

Border regions are not often associated with innovation and economic prosperity. And even when they are prosperous, cross-border interaction is still mostly limited. The opening up of borders in Europe has presented new opportunities for firms located in these border regions to co-operate for innovation and knowledge to flow across borders. Despite the reduction of the importance of borders, firms seeking to access cross-border knowledge resources need still to ‘cross’ the border and address the various effects it brings. This paper therefore asks the question of how the presence of a border affects the processes by which firms attempt to build up productive co-operations for innovation. We use a heuristic of collaborative innovation across borders as building up through four sequential cooperation stages, and each of these different stages is susceptible to different kinds of border effects. Using a case study of firms co-operating across the Dutch-Flemish border, we empirically explore these border crossing processes in order to shed further light on how border processes play out.     

A place to transform: creating caring spaces by challenging normativity and identity

Like all spaces, concrete caring places both shape and are shaped by understandings and constructions of normativity and identity. The traditional understanding of care for older people, imagining clearly demarcated dyadic roles, is firmly embedded in heterosexual logics of relationships within families, the own (family) home and institutional support. Social and residential places for older people thus both assume particular gender and sexual identities and contribute to a (re)production of the very normativity. But how can this interlinkage between the construction of caring spaces and the normativity of identities be understood and, possibly, challenged? In this article we discuss the transformative potential of the social (and partly residential) space of La Fundación 26 de Diciembre, in Madrid, Spain, which opened up to specifically support older LGBT people. Drawing on an in-depth case study we explore a space that allows visibility of different forms of living and caring practices of people with different genders, sexual preferences, origins, classes or political backgrounds. Through the daily life narratives of the people who work, volunteer or simply use the centre we discuss the potential of challenging the restricted notions, assumptions and constructions through which particular places gain both social and political meaning. The article highlights the transformative power of the active and collective making of caring spaces through which narratives of care, collective sexual and gender recognition and practices of caring relationships can replace both traditional/informal forms of living together and institutional spaces that provide professional care.     

The wealthier inhabitants of Croydon in the late sixteenth and early seventeenth centuries

This article examines the wealthier inhabitants of Croydon in the late sixteenth and early seventeenth centuries, focusing on differences in wealth, ownership of property and social relationships. Using wills and subsidy lists, four broad categories of people were identified: gentlemen, yeomen, tradesmen and craftsmen and widows. There was no simple gradation of wealth between these groups; although gentlemen were generally among the richest subsidy payers, yeomen and tradesmen could also figure. In terms of social relationships and the ownership of property, there were differences. Gentlemen tended to marry within their own social group, appoint other gentlemen as overseers in their wills and were more likely to own land outside Croydon. The social relationships of yeomen and tradesmen/craftsmen were more focused on the town itself, as were their land purchases. Two groups of individuals can therefore be seen, not one homogenous entity as some scholars have argued.
