绉丝纱在中国古代纺织品修复中的应用

Crepeline是一种较为薄透的平纹丝织物,在欧美等国的纺织品文物保护中应用较为广泛,尤其对于脆弱丝织品的保护具有非常好的效果。近年来,此种织物在中国纺织品修复中的应用也日渐趋多。由于中国市场上无处购买该材料,为了降低成本并满足中国古代纺织品的修复需求,中国丝绸博物馆与浙江理工大学合作研发了该种修复用织物——绉丝纱。本研究介绍所研发绉丝纱的工艺参数和性能特点,及针对不同类别的中国古代纺织品,采用绉丝纱作为修复材料时的使用方法。即通常将其包覆于纺织品文物表面,以针线缝合的方式固定,并注意缝合时尽量减少针线穿过文物的次数。其包覆的形式,按包覆范围可分为整体包覆与局部包覆;按包覆方式可分为单面包覆、双面包覆及叠加包覆等。研究表明,绉丝纱包覆是一种值得推广的纺织品保护方法,尤其是对已无法承受针线过多穿缝力度的纺织品。如能够解决绉丝纱裁剪后的边缘脱线等细部问题,将会更加扩大其使用的范围。     

‘We wouldn't be dead for quids’: Hansonism,Fascism, Death and Difference

There are a number of ways in which the Australian political movement led by Pauline Hanson can be implicated in the totalitarian episodes of the twentieth century. But there are also significant differences between what Hansonism presents us with in Australia and what totalitarianism has presented us with in Europe, in the fascist and Stalinist regimes with which totalitarianism is associated. The suggestion in this paper is that totalitarianism can be understood in schematic terms as a mutation of the symbolic order through which differences have been arranged and evaluated in Western thought since the time of the ancient Greek philosophers. Specifically, it belongs with the history of the binary opposition. Its mutation is that it attempts to realize — that is, to accomplish in reality — the fiction of the binary structure, which is its claim to comprehend or to be able to totalize and exhaust the space over which its positive and negative terms must govern. In a contemplation of death and difference, the question is considered here of what is to be gained for thought in characterizing Hansonism as a neo‐fascist phenomenon.     

The Changing Face of PEQ

Abstract

The spectacular relief of the sandstone inselbergs is maintained by an interplay of geological structure and weathering/erosion processes, in that vertical joints and faults provide the foci along which most weathering and erosion take place. There are three major varieties of sandstone breakdown; the first is failure of large rock masses along vertical joints, leading to rockfall. Associated with this process is the mechanical breaking of falling blocks upon impact, in some cases right down to the origjnal sand grains. Rockfall maintains vertical or steep slopes, provided basal talus is removed. The second variety is liberation of small blocks by weathering along closely-spaced joints and bedding planes. Rock prone to this style of erosion tends to be less steep and may have basal slopes buried by rubble. The third variety is grain by grain weathering by solution of cement. This process is the most fundamental, as it not only wears away the surfaces but attacks joints, leading to the processes described above. Grain by grain weathering is slowed or prevented on some surfaces by development of oxide rinds, particularly where run-off is concentrated.

These processes result in deposition of debris at slope bases, but in most cases the debris is quickly reduced to sand and removed by wind and water. Relatively clean slope bases allow slopes to retreat parallel to themselves. Where debris collects faster than it is reduced to sana, slope angles tend to decline until they reach the angle of repose of the debris.

Differences in structural expression of the various lithological units result in differing erosional characteristics. The Saleb Formation is typified by relatively gentle slopes littered with debris, due to thinly spaced joints. The Ishrin Formation, witll widely spaced vertical joints, is typified by rockfall of large masses. It is the major cliff-former. Grain by grain weathering, influenced by variations in varnish development, has produced spectacular tafoni on some Ishrin cliffs. The Disi Formation is extremely friable and although slopes are relatively gentle they are mostly rubble free. The Disi in many places forms rounded domelike shapes which may be due to exfoliation along pressure-relief joints. The Um Sahm Formation is highly fractured and similar in appearance to the Saleb.

Igneous rocks, where exposed below the sandstones, are undergoing chemical weathering, particularly along joints. The results are tors, tafoni, and large amounts of grüss.

The desert floor between inselbergs is in some places a bare bedrock surface with an integrated drainage network, and in other places a sand or playa surface. Running water seems to have been a major agent in shaping the floor, but is less important now than in the past. Transportation of sand by wind is common but there is no evidence for significant eolian aggradation or degradation at the present time.

A minimum rate of surface retreat by grain by grain weathering is 5 cm./1,000 years, based on weathering ofNabataean ruins. Overall slope retreat should be significantly greater, due to added effects of rockfall and removal of blocks by running water.     

The persistence of authoritarianism as a source of radicalization in North Africa

September 11 and subsequent terrorist attacks across the globe have led to an increased emphasis on security issues among political leaders globally. While this preoccupation with security has not led to the abandonment of democracy promotion efforts, there is no doubt that initiatives that have the demise of authoritarianism as their core objective, have become less of a priority in recent years, with spending on projects seemingly unrelated to security issues and the 'war on terror' declining, and pressure on heads of state to embark on democratization processes weakening. This article contends that the relieving of pressure on heads of state to introduce democratic reforms is detrimental to the desired goal of increased security, given that the radicalization of Islamists is closely related to the prevalence of authoritarianism. In short, it is argued that there is reason to believe that the West's tendency to allow violations of basic democratic principles, and failing to employ genuine pressure for regime change in the various MENA states, which are actively partaking in the 'war on terror' on the side of the US, is counterproductive in the longer run. While it is impossible to predict when terrorism committed by radicalized Islamists will end, and it is almost certain that terrorist attacks will recur in the future and that we have to learn to live with the risks, it is possible however to do something about the scale and frequency of such incidents. This article argues that through positive democracy promotion resulting in real democratization, it is indeed possible to obtain increased security.     

Entitlement Failure?

In this article, the literature around the entitlement approach to famine is assessed against the background of recent developments in economics which are perceived to have increasingly encroached upon the previously neglected subject matter of the other social sciences. In this light, emphasis is given to the tension that exists in the entitlement approach between its micro-foundations and macro-consequences and causes. This, in turn, is related to the broader problem in social theory of the relations between structures and agency. Whilst it is found that the entitlement approach does embody an implicit causal content in the filtering of socioeconomic mechanisms through the distribution of individual entitlements, it is ultimately argued that the approach is primarily suited to investigative rather than causal analysis.     

Approaches to style in lithic archaeology

A key issue in lithic archaeology is how to identify the respective roles played by ethnicity and activity—that is, style and function—in the formal variation exhibited by stone tools. This paper argues that style is most profitably regarded as the ethnic idiom imparted to lithic technology in each and all of its aspects due to the culture-historical context of its manufacture and employment. Style is thus a full complement of function, and it is to be looked for wherever artisans encounter options of form and use to “choose” from in pursuing a given task. Because it equates ethnicity with functionally equivalent choice, this is labeled the isochrestic approach to style. Contrasted to this is the iconological approach, which restricts style solely to those aspects of formal variation that artisans purposefully invest with symbolic content reflecting self-conscious social groups. Pottery decoration appears to reveal such investment and therefore ceramic sociology is a feasible enterprise. However, a parallel iconological approach to stone tools is much less promising. At least as it is exemplified by the writings of Lewis Binford, lithic sociology would seem to have little substantive grounding in the relevant empirical data, to be argued within what may be an unsound theoretical frame (including the distinction between curative and expedient technologies), and in any case to resist translation into a workable analytic machinery. Not least among the reasons for this last is the fact that stone tools do not possess formal variation wherein iconologically significant investment can be objectively identified and defined. The archaeological frame of reference within which the isochrestic and iconological approaches are discussed is largely contributed by the classic Paleolithic sequence of the Perigord region of southwestern France.

论清末舆论放大现象的成因

清末舆论放大现象最为集中的体现是报刊发行量的飞速扩张;之二是舆论界自身定位为监督政府,并形成了强大的公共领域;之三是受众由以官吏为主转向以社会公众为主;之四是社会各阶层更加注重报刊舆论。至于舆论放大的成因,一是新闻界推行的白话运动,二是政府的引导与推动,三是政府与民间合力促成的讲报、阅报机构,综合催发清末的舆论放大效应。清朝政府对之未予正视,结果致使局势一发而不可收拾,王朝统治也随之荡然无存。     

Proximity,trust and morality in networks

Network interaction is embedded in social settings, which allows for the development of trust. Trust is supposed to be an efficient functional equivalent of contracts, guarantees, insurances, safeguards, etc. Trust between actors reduces transaction costs. However, trust cannot be introduced and enforced within interaction relationships. It is argued that trust is more likely to occur and to be prevalent when actors have the spatial capability for personal, direct interaction. Thus, proximity and trust are supposed to be positively related to each other. Proximity is strongly interrelated with embeddedness. In the discussion about morality in organisations, there is an assumption we referred to as the 'moral spill-over effect': it is impossible, it is said, to restrict moral competencies and moral behaviour to one particular situation, environment, or topic. However, we argue that, even though trust is a term that is described in moral theory, trust and morality are not necessarily positively correlated. This means that even if embeddedness and proximity in a network lead to an increase of trust between network partners, it does not necessarily produce moral spill-over effects. Thus, proximity and morality do not necessarily have to be positively correlated with each other. The influence of proximity on morality can be positive or negative, depending on the social surrounding in which network collaboration is embedded.     

L’eugénisme et la protection de l’espèce humaine dans les lois bioéthiques Vers une nouvelle construction juridique de l’homme

The aim of this study is to bring to the fore some issues concerning human rights unleashed by the bioethical laws of July 1994, regarding the application of biotechnologies to reproduction. To achieve this aim, an analysis is offered of the legal arrangements, set by law in order to determine the procedures related to the selection of embryos and the transformation of their genetic characteristics. These analyses are then compared to the eugenic procedures instituted in the West during the first half of the xxth century. As a result, the idea is challenged, that eugenics is a category fit for the characterizing the biopolitical project contained in the bioethical laws. To conclude, the aim is made that what is a stake, as far as human rights are concerned, is the fate of the idea of man and of the subject of rights that is involved in these laws.     

博物馆文物保存环境质量标准研究

我国大气污染严重,环境质量恶化使文物受损影响日益明显。上海、重庆、广州三市博物馆环境质量检测调查说明其现状与文物保护的要求还有相当距离,有些甚至还处于污染相当严重的地步。博物馆文物保存环境影响因素主要是温湿度、光线(可见光、紫外光)、污染气体(包括尘埃),不同材质的文物受各种环境因素影响在程度上是不同的。有的是起主要作用,有的则是起协同增效作用。研究其反应机理、反应速率,量化它们之间的关系,将是制定出文物保存环境质量标准的重要依据。 文物保存环境质量标准要求达到最大限度降低环境因素对文物所造成的损害,但受治理技术、监测技术、经济的许可、合理程度等方面的制约,制定分级标准将有利博物馆的环境治理实施和监测。     

Historical Use of Metal Tie-Rods in the Italian Territory: Treatises,Essays, and Manuals through Four Centuries of History

The use of metal tie-rods in buildings is documented and visible in many Italian areas since the 15th century. This article refers to the study of treatises, manuals and essays from the 15th to the early 20th century, mainly in the Italian context with some exceptions of certain foreign texts that, due to their diffusion and importance, have greatly influenced the technical literature on the subject. Technology is an expression of the social, economic, cultural, political and juridical events of a country and, as such, is deeply linked to the times and territories in which it develops. However, it is also closely linked to the laws of nature and to forms of communication, therefore it is useful to compare, underlining the analogies and differences, the knowledge and the ways of the productive and technical process in a long-term analysis.

IMAGINATION AS A CATEGORY OF HISTORY: AN ESSAY CONCERNING KOSELLECK'S CONCEPTS OF ERFAHRUNGSRAUM AND ERWARTUNGSHORIZONT

Reinhart Koselleck is an important thinker in part for his attempt to interpret the cultural changes resulting in our modern cultural outlook in terms of the (meta)historical categories of experience and expectation. In so doing he tried to pay equal attention to the static and the changing in history. This article argues that Koselleck's use of “experience” and “expectation” confuses their metahistorical and historical meaning, with the result that his account fails to do justice to the static, to continuity in history, and mischaracterizes what is distinctive of the modern era. As well as reconfiguring the categories of experience and expectation, this essay also introduces a third category, namely, imagination, in between experience and expectation. This is done to render intelligible what is obscure in Koselleck's account, and as a stimulus to a study of history that divides its attention equally between the static and the changing. In fact, it is argued that the category of imagination is pre‐eminently the category of history, on the concrete historical as well as the metahistorical level.     

The significance of values: heritage value typologies re-examined

A critical discussion of value typologies for heritage conservation and management is offered, from the perspective of objects and urban conservation, in light of a review of published literature on heritage values. It is suggested that value typologies are often designed and implemented without understanding the implicit consequences of the inclusion and omission of ‘values’. It is also suggested that typologies often fail to prompt the necessary questions to develop satisfactorily detailed understandings of heritage significance, resulting in decisions being based on implicit, rather than explicit, value assessments in practice. Mindful of the problems associated with ‘universalising’ context specific typologies, a broad framework for assessing and communicating significance is proposed. In order to encourage holistic approaches, the framework is designed to combat the false dichotomies of cultural/natural and tangible/intangible heritage; it is hoped this will make the framework widely applicable. Without downplaying the necessity of diverse participation in assessing significance, the framework is designed to identify aspects of weakness and preference in cases where adequate consultation is not possible.     

Urban Unemployment and Migrants in Africa: Evidence from Harare 1985–1994

Unemployment is a major problem in urban centres in sub‐Saharan Africa. The impact of policies associated with structural adjustment programmes has frequently meant major formal job losses in both the public and private sectors. Although it is widely recognized that there has been a major (further) shift into the informal sector, it is also often claimed that ‘unemployment’ rates have greatly increased. When it is also assumed that net rural–urban migration has continued at a rapid pace, this is believed to be a significant contributor to the rise in unemployment. However, because ‘unemployment’ and ‘underemployment’ are hard to measure and to keep discrete when studying urban Africa, it is apparent that there is much confusion over current levels and trends in unemployment. This article discusses the problems of analysing African urban unemployment, drawing in particular on a recent ILO report, and presents evidence from long‐term research on migrants in Harare which casts doubt on the extent to which net in‐migration is a major factor contributing to unemployment in contemporary, economically adjusting sub‐Saharan Africa.     

"Testimonies from the Field": The Coming of Christian Science to Australia, c. 1890–1910*

The account of the coming of Christian Science to Australia given in this article is based on testimony contributed by early adherents to the two main church publications, The Christian Science Journal and the Christian Science Sentinel , supplemented by Church records and other sources. The first two decades are covered, from the earliest known intimations of interest to the death of Mary Baker Eddy in 1910, when a Christian Science presence in Australia was assured. Interest shown by writer Miles Franklin, and her association with Melbourne adherents such as leading feminist Vida Goldstein, provides the starting point. The focus is on positive responses. It is postulated that in addition to the documentary and expressive value of the testimonies, they point to problems of class and health in turn-of-the-century Australia. A preponderance of women in both the testimonies and the practice is evidenced, and the openness of progressive women to new approaches is noted. With reference to male testimony, it is suggested that further research into responses to American ways in religion by the urban midle class would be very valuable.     

经济一体化背景下的区域溢出分析

从溢出的角度研究区域间的互动关系是一个全新的视角。本文利用协方差统计模型对广东省与其他省区的溢出关系进行分析。结论是:在航空距离影响下,广东对所有省区都具有强度不同的正溢出效果,发挥了区域带动作用。在接受溢出方面,除了四川,甘肃,宁夏和黑龙江以外,其它省区对广东的溢出均表现出强度不同的正效应。对比分析广东对外溢出和获得溢出,可以看出经济水平邻近的长江三角洲地区、地理邻近省区均与广东表现出较强的相互正溢出效应。在区域间信息化缺口的影响下,广东与各区域之间溢出强度下降。     

Strategy and contingency

The determination that strategy should have a long‐term predictive quality has left strategy seemingly wanting when having to address what are currently called ‘strategic shocks’, such as the recent Arab Spring and the NATO commitment to Libya. The focus on grand strategy, particularly in the US, is responsible for this trend. Its endeavour to mitigate risk in the national interest is inherently conservative, rather than opportunistic, and it is favoured and probably required by powers that are committed to the status quo, that need to manage diminishing resources, and that are dealing with relative decline. Strategy as traditionally but more narrowly defined by generals for use in a military context, is much more exploitative and proactive. Precisely because it is designed to be used in war it presumes that its function is offensive, that it will have to deal with chance and contingency, and that its aim is change. Its task is to deal with the uncertainties of war, and to respond to them while holding on to long‐term perspectives. Clausewitz addressed the issue of ‘war plans’ in book VIII of On war, but the thinker who did most to inject planning into European strategic thought was Jomini. His influence has permeated much of American military thinking. The effect of nuclear planning in the Cold War was to ensure that strategy at the operational level became conflated with broader views of grand strategy—not least when the Cold War itself provided apparent continuity to strategic thought. Since 1990 we have been left with a view of strategy which fails to respond sensibly to chance and accident. Strategy needs context, and a sense of where and against whom it is to be applied. Its core task is to embrace contingency while holding on to long‐term national interests.
