张衡地动仪的发明、失传与历史继承

地动仪的发明和失传存在深厚的社会背景.悬挂物对地震的良好反应是诞生科学思想的物质基础.地动仪是对天然验震器的发展,张衡不仅在利用物体惯性测震上,也在检测和记录地震微弱信号上有技术创新,成功测到公元134年12月13日陇西地震.天诫观念把自然现象与社会问题混为一谈,导致张衡晚年和地动仪的悲剧.仪器可能失传于东汉末年,当时发生了洛阳大火、毁铜铸钱、京师搬迁、人口剧减和灵台被毁等极端严重的社会混乱.张衡的科学思想和实践对现代地震学的起步发挥过思想启迪作用.对地动仪的研究需要开展科学实验,学术观点的统一只能建立在科学实验的基础上.     

Exploring Spatial Relationships between Material Culture and Language in the Upper Sepik and Central New Guinea

ABSTRACT New Guinea is the most linguistically diverse region in the world. Over 1,000 languages are found there. Unsurprisingly, controversy exists concerning the degree to which this diversity has been shaped by migration or interaction. At the centre of this controversy is the putative origin and migration path of Austronesian speakers. The advent of Lapita ceramic ware in Melanesia around 3,000 years ago is seen by some as important evidence for their arrival; nevertheless the validity of using Lapita as a marker for Austronesian populations remains in question. The Upper Sepik is one of New Guinea's most linguistically heterogeneous regions. Because it is not marked by far‐reaching exchange systems the region's language and material culture distributions provide potential for exploring such issues. This paper discusses these in the context of an analysis of important ethnographic collections from the region. It is shown that when material culture is assessed technologically and stylistically it is easier to determine an effect for important variables such as language and distance. Additionally, it is demonstrated that as men and women often have different levels of mobility and sociality, classes of material culture belonging to each may differentially reflect important socio‐historical processes.     

New experimental data on the distance of sling projectiles

The range of stones cast by slings used in the past is debated. In the Central Andes, slings are asserted to be important weapons of prehispanic war, and have been recovered archaeologically. Rolled river cobbles and stones presumed to be slingstones found at fortified hilltop archaeological sites are presented as evidence that slings were used at these fortifications. Yet sling use has not been adequately tested at hillforts. Experiments conducted in Europe by a novice slinger have attempted to illuminate the range of sling cast stones at ancient hillforts. Data acquired from native slingers is necessary to more accurately assess distances achieved by projectiles launched by slings. We present data from sling experiments carried out in Puno, Perú among Quechua-speaking herders who are experienced slingers. The results demonstrate that a prior model of the maximum theoretical distance of sling cast stones underestimates their range. Results also show significant differences in the use of slings by men and women, and by different age groups. These new data permit a better approximation of warfare that has bearing on our interpretation of fortified sites.     

Remote sensing techniques for reconstructing a vast Neolithic settlement in Southern Italy

The combined application of remote sensing techniques is often the most effective way for deepening the knowledge on very large archaeological sites (several hectares). In particular, geophysics and aerial photography could yield very detailed information on buried structures not only outlining their location but also, in many cases, defining their planimetry. Moreover, the accurate geocoding of different data sets and the use of GIS for their integration allow to extract the most comprehensive information from a combined study.     

‘Unfurling the banner of reform’: public opinion,nationalism, and Facts and Figures from Italy

This article reconsiders the neglected Italian correspondence of the Cork-born wit, essayist, and journalist, Francis Sylvester Mahony (‘Father Prout’). Re-assessing his traditional reputation as a Tory polemicist, it explores his movement away from the conservative, pro-Union politics of his contributions to Fraser's Magazine in the 1830s, and examines how, despite his continuing rejection of popular O'Connellite nationalism, he came to offer a broadly sympathetic portrait of Young Ireland in the articles he contributed to the London Daily News in the 1840s. It also traces the development of his political thinking at the beginning of the Famine era, focusing, in particular, on the influence of the resurgent nationalist movement in Italy on his reassessment of the Irish question.     

Small shifts in handedness bias during the Early Mesolithic? A reconstruction inferred from Microburin technology in the eastern Italian Alps

This study discusses the existence of a variability recorded in lateralization indexes of proximal microburins, a by-product of the individual manufacture of microliths, in a sample of Sauveterrian sites from the Italian Eastern Alps. At first glance, such variability may appear to support the existence of customary handling, pertaining perhaps to an ensemble of normalized technical procedures accomplished by the members of the human group regardless of site type, context and economic activities. However, plotting the patterns in lateralization index against the regional Sauveterrian chrono-cultural sequence reveals a diverse correlation emerges and indicates how the early settlement phase involved greater functional differentiation among sites used by selected human groups compared with the successive phases, when this pattern vanishes. This trend may correspond to the decrease in lateralization observed on skeletal markers from the Upper Paleolithic to the Mesolithic, linked to the change in technological models and techniques employed in food gathering. The implications of this research at different levels are also discussed.     

意大利工业区与华人的双重挑战

论文分析了全球性竞争压力对工业区适应机制的影响及工业区的竞争优势以及工业区内部形成的华人经济的潜在威胁,探讨了在新的条件下将这种威胁转化为新的发展机遇的可能性。认为华人经济的特殊优势使华人企业越来越活跃,但却使当地企业日益萎缩。这反过来又促使当地经济整体进行转型;华人企业家的某些优势在于其跨地区和跨国网络;华人移民对其祖籍国潜在商业伙伴的能力和品德有深度了解,如果能发挥中介作用,意大利当地企业就能使其工业生产及产品销售国际化。     

Closing the Neoliberal Gap: Risk and Regulation in the Long War of Securitization

Abstract: When US military commanders refer today to the “long war”, they could more instructively refer to the “long war of securitization”, involving both practices of war and reconstruction that have always been based on a therapeutic logic of preemption and an endgame of protection from global economic risk. Since the early 1980s, the centrepiece of US foreign policy has been the securitization of the Persian Gulf region, with the newly created United States Central Command (CENTCOM) given the task of effecting a grand strategy that has subsequently been consistently based on two interrelated tactics: first, the discursive identification and positing of the Persian Gulf as a precarious yet pivotal geoeconomic space, essential to US and global economic health; and second, the enactment of a dual military–economic securitization strategy to secure, patrol and regulate designated “vital interests” in the region. With the rhetorical power of “risk management” perhaps more palpable today than ever, this paper reflects on the neoliberal discourses of “risk” and “regulation” that sustain a “long war” in which the perennial potentiality of a volatile global political economy necessitates securitization by US military force.     

Stable isotopes and human diet in central western Argentina

Central western Argentina is the southern boundary of prehispanic maize in the archaeological record. This paper explores the stable isotope information from human bone (δ¹³C, from collagen and δ¹³C from apatite) and tooth (δ¹³C from enamel) samples in order to characterize the temporal and spatial trends of these isotopes and to understand them in terms of human diet. We analyzed 104 human individuals from the last 6000 years. Using the Kellner and Schoeninger (2007) model the results shows a high variation in human diet with few human individuals with a notably high significance of C₄ plants (probably maize) as an energy source and these samples have a chronology around ca. 1000 years BP. On the other hand a high variation in an individual’s dietary life history is shown by differences between δ¹³C collagen, apatite and enamel.
