The manufacture of Aurignacian split-based points: an experimental challenge

Hunting is one of the areas of human activity that sees the most significant changes in the period from 40 000–35 000 BP in Europe. In this respect, the Aurignacian technocomplex shows technical innovations, notably with the fabrication of split-based points (SBP) in antler and the mass production of bladelets, arguably to serve as weapon armatures. Yet, little experiment work has been dedicated to this question. To begin to fill this gap, we have designed an experimental program devoted to testing and assessing the design, manufacture and use of Aurignacian weaponry.     

Technological successions in the Middle Stone Age sequence of Diepkloof Rock Shelter,Western Cape,South Africa

The southern African MSA comprises a series of phases of unique technological innovations that fuel current models on the evolutionary processes of Anatomically Modern Humans. However, the nature and variability of these technological phases remain poorly documented. This study reports on the previously unpublished sequence of Diepkloof Rock Shelter (South Africa) and investigates the main technological changes therein, particularly emphasizing the emergence, succession and disappearance of the Still Bay (SB) and the Howiesons Poort (HP). We argue for technological change that occurred at different rates and under the influence of variable driving factors. Our model implies that the SB and the HP are not related to the influx of new populations but have regionally specific origins. Unlike the other techno-complexes, the HP at Diepkloof is subdivided into different phases (Early, Intermediate and Late) but only the upper phases resemble the so-called “classic” HP. Finally, the technological sequence of Diepkloof questions the homogeneous picture which has been so far assumed for the southern African MSA and places emphasis on the importance of exploring long regional sequences.     

Introduction

Abstract

For all of its political drama, the health care debate appears consumed with bureaucratic minutiae quite distant from political philosophy. Yet in important respects that debate is intimately connected with the founding premises of the modern technological project of the mastery of nature for the relief of man's estate as envisioned by René Descartes and Francis Bacon. This essay uses a recent discussion of the health care debate by bioethicist Daniel Callahan to raise some fundamental questions about the role of technology in our medical culture. It argues that modern health care is the Cartesian project come of age, and it uses Descartes' Discourse on Method to reflect on the possibility of a sensible politics of technology in our time.     

高技术园区与工业区之整合

地区高技术园区和工业区原有产业分工功能,随着日益激烈的市场竞争逐渐转变成竞争关系。高技园区与工业区原有规划目标提供企业厂商良好的投资生产环境,但是生产与市场重迭所产生的竞争问题,将降低彼此竞争力。本文经由探讨两岸高技术园区发展经验,指出两类团区应采取整合方式支撑地区经济总体发展,并提出对两类园区整合策略的构思。     

我国旅游业技术创新水平的区域空间分布特征——基于专利数据的统计分析

本文基于专利的统计数据,分别采用绝对指标、相对指标和特化系数来评价我国旅游业技术创新水平的空间分布特征。研究结果表明,采用绝对指标评价的旅游业技术创新水平呈现“东高西低”的格局;而采用相对指标（单位人口的旅游业专利申请数量）评价的结果表明,东部地区仍处于领先地位,但与绝对指标评价结果相比,西部地区的排序明显升高;东部地区旅游业发明专利特化系数较高,如北京、天津、上海、广东、海南均在1．1以上,但是全国大多数省市的旅游业专利还属于实用新型和外观设计特化类,说明我国旅游业技术创新结构并不完善。     

从创新成果管窥文物科技保护发展趋势

中国文物科技保护工作起步于20世纪50年代,始终紧跟我国社会经济和科学技术的发展,以应对文物保护及其保存和开放展示环境面临着的诸多挑战为导向,聚焦基础研究、保护技术与装备研发、保护制度与规范标准研究、保护技术平台建设等展开多项科技攻关,取得了一系列成果。本文着重从文物保护科学和技术创新成果进行梳理,阐述了我国文物科技工作的发展趋势。结果表明,我国的文物保护科学研究从闭门研究、各自为战到资源开放、互相合作、凝练共性、共克难关;从随意性到标准化,建立共同话语体系;以问题为导向,支撑作用日益显著;由抢救性保护向抢救性保护与预防性保护并重转变,基本实现了“十三五”规划提出的在理论、技术、装备、标准建设等方面取得系统突破的目标。     

一类潜在的石质文物表面防护材料:仿生无机材料

微波技术在砖石质文物含水率检测中的应用

水是造成砖石质文物劣化的主要因素之一,因此探明其在文物内部的分布、运移规律是开展保护研究的重要基础。微波技术在检测材料内部的水分含量方面表现出较好前景,但在文物保护领域还未普遍应用。基于此,本研究首先介绍了微波技术的理论基础和相关仪器,并选取山西省的长春玉皇庙为对象,针对砖石材料的内部含水率开展了室内样块检测和现场墙体检测。结果表明,微波技术能够较为准确地揭示出文物内部的空间含水率分布规律,这对于研究其病害成因等具有重要作用。此外,与其他多种无损检测技术相比,微波技术检测材料含水率的优点更多,值得文物工作者进一步研究与应用。     

New tech spaces for old tech places? Exploring the network of research and technology organizations across North Italian Regions

This paper explores the industrial affiliation and linkages of research and technology organizations (RTOs) in nine North Italian regions highly specialized in advanced manufacturing and introduces a methodology to assess the potential for a cross-regional technology platform. RTOs are supposed to operate in the development and application phases of innovation and are expected to provide access to key enabling technologies and R&D infrastructures. An original survey panel of 55 Italian RTOs is used and Social network analysis is introduced to assess the potential of RTOs to operate as a single cross-regional platform across key industrial and technology domains. Centrality measures are used to build an empirical model on the factors that drive the higher centrality of RTOs. Centrality is increased by convergence on few key technology priorities and is positively correlated with collaborative ventures, the number of contracts with firms and the presence of distinctive R&D infrastructures. Such a platform rests on specialized regional hubs, it operates with no gatekeepers and it only partially exploits geographical and technological proximity within the network. Future research avenues are discussed to improve the function of technology diffusion of RTOs in a cross-regional perspective.
