The Archaeology of California

Stimulated by several important, recent empirical advances, California archaeologists are engaged in a series of lively debates. These advances include new discoveries about the early peopling of western North America and sustained occupation of the California coasts as early as 12–13,000 BP. There also have been significant new developments in the role of paleoenvironmental change in cultural evolution, the emergence of long-distance interaction spheres, the presence of intensive craft specializations, and the appearance of sociopolitically complex hunter–gatherers. This article addresses these issues—and several others—with a view to the general interests of scholars worldwide. The exceptional heterogeneity of California ecosystems (from deserts to dense redwood forests to bountiful offshore islands) and the remarkable cultural diversity exhibited by the dozens of major groups who made these lands their home combine to produce a complex indigenous sociopolitical picture. Current understandings reveal myriad trajectories of cultural change across nine major subregions of the state.     

盱眙东阳汉墓两件木胎漆器髹漆工艺探讨

江苏盱眙县境内的东阳秦汉古墓群是一处重要的秦汉遗址.迄今为止,墓葬出土了大批精美的漆器,为了解汉代广陵国髹漆工艺提供了珍贵的资料.为了解其髹漆工艺特点,采用了切片技术、X射线衍射光谱(XRD)、X射线荧光光谱(XRF)和傅立叶红外吸收光谱(FTIR)等分析方法对其中两件木胎漆器进行了分析研究.漆膜切片显示素色漆器的漆膜由漆灰层和黑色漆层构成,而彩绘漆器由三层结构组成.分别为灰地、底漆层和色漆层;XRD图谱发现漆灰层中的填料主要为石英(AiO2)和钠长石(NaAISi3O8),漆膜中的红色颜料为朱砂(HgS);红色漆膜的XRF显示了其主要元素是Hg和S,包括Ca、Si、Cu和Fe等微量元素.漆膜的FTIR分析数据显示漆膜中在1630cm-1和1576cm-1处存在着可能是苯环骨架振动的红外吸收峰.研究结果说明了本地髹漆工艺主要分为三个步骤:1)髹漆灰,漆灰层是由生漆调和研磨成细粒的钠长石矿物构成,它能制作出厚度约0.1～0.2 mm薄漆灰层;2)髹底漆,厚度约为0.02～0.09 mm;3)彩绘,红色漆膜中的颜料为朱砂,朱砂含有微量的Ca、Si、Cu和Fe等杂质,表明其来自矿采.     

Explaining the monopoly in shell-bead production on the Channel Islands: drilling experiments with four lithic raw materials

Significant political and economic developments among the Chumash of southern California were catalyzed in part by the emergence of an intensive, specialist-driven shell-bead industry during the second millennium CE on the Santa Barbara Channel Islands. The production of millions of beads depended in turn on the availability of lithic microdrills of standardized form and materials. Channel Islanders quarried a particular stone type, a blocky Monterey Formation chert, from multiple outcrops situated close to the eastern shores of Santa Cruz Island. Rich archaeological assemblages document the lithic and shell byproducts of these intertwined production systems, each of which endured for several centuries (CE 1150–1819). Islanders invariably chose Island chert for making microdrills: hundreds of thousands of specimens recorded to date are of this material. Furthermore, nearly every microlith in all of Chumash territory (post CE 1150) was produced on the islands; the large populations on the mainland did not participate in microlith making or bead making after CE 1150–1200. We argue that this pattern had its roots not only in the patchiness of key resources and shifting regional social relationships, but also in the physical properties of available raw materials. Here we experimentally assess the properties of Santa Cruz Island chert alongside three important mainland raw materials—Grimes Canyon fused shale, Coso obsidian, and Vandenberg chert—that potentially could have been tapped to make microliths. We test the proposition that Island chert outperforms other lithic materials in drilling efficiency and drill use life. Our experimental results from 108 drilling trials reveal sharp distinctions in performance characteristics across the four materials. We infer that the process by which Islanders became the more-or-less exclusive manufacturers of shell-bead currency in southern California was facilitated by both the efficacy and physical properties of the Island cherts and the propitious locations of the outcrops.

Patent portfolio analysis of cities: statistics and maps of technological inventiveness

ABSTRACT

Cities can be considered as engines of the knowledge-based economy, because they are the primary sites of knowledge production activities that subsequently shape the rate and direction of technological change and economic growth. Patents provide rich information to analyse the knowledge specialization of specific places, such as technological details and information on inventors and entities involved. The technology codes attributed at the level of individual patent documents can be used to indicate the diversity and scope of the knowledge claims underlying a specific invention. In this study we introduce tools for portfolio analysis in terms of patents that provide insights into the technological specialization of cities. The mapping and analysis of patent portfolios of cities exploits data derived from the Unites States Patent and Trademark Office (USPTO) and dedicated tools (at https://leydesdorff.net/software/patents/). The results allow policy makers and other stakeholders to identify promising areas of further knowledge development, including smart specialization strategies.     

Path-development trajectories and barriers perceived by stakeholders in two Central European less developed regions: narrow or broad choice?

This paper aims at the comprehension of feasible development trajectories conceptualized within the new path-development model in the case of two less developed regions in Central Europe (CE). The main new element of this paper comprises the examination of the perception of key barriers and mechanisms hindering particular evolutionary trajectories by regional stakeholders and their comparison with those conceptualized in the literature. Although conceptual characteristics of prevailing path types in different regional innovation systems do exist, empirical verification from less developed regions such as those in CE is insufficient. On the basis of interviews with regional stakeholders, a typology of barriers for pathways conceptualized to date was elaborated from a CE perspective. Our study showed that the feasibility of a more radical path is hindered by a wide range of barriers operating at different levels. The elaborated typology of barriers for various path-development trajectories outlined the main hindrances constraining key regional actors, linkages and institutions. Given the general weakness of the overall RIS, path-extension and path-modernization trajectories are bound to be the most realistic options for this type of less developed regions. Our study revealed existing regional dynamics as built predominately upon incremental changes within rooted but prospective industrial branches.     

FLEXIBLE SPECIALIZATION, UNCERTAINTY, AND THE FIRM: ENTERPRISE STRATEGIES IN THE WOOD REMANUFACTURING INDUSTRY OF THE VANCOUVER METROPOLITAN AREA, BRITISH COLUMBIA

In this paper, we articulate the relationships between strategies of flexible specialization, uncertainty, and the firm in order to emphasize the internal differentiation of flexibly specialized regions. Conceptually, the paper argues that this variability is an implication of uncertainty which has been neglected in the literature. In particular, in response to uncertainty, firms develop different types of flexibility with respect to production, technology, and employment in sometimes novel ways that do not correspond to ideal types. Empirically, the argument is demonstrated through a detailed examination of several case study firms operating in the wood remanufacturing industry of the Vancouver metropolitan area, British Columbia.
Ceffe étude montre comment s'amculent les relations entre les stratégies de spécialisation flexible, les incertitudes du marché et la firme afin de souligner les différenciations à l'intérieur des régions à spécialisation flexible. De façon conceptuelle, on discutera ici du fait que la variabilité découle de l'incertitude du marché, point sur lequel on n'a pas beaucoup écrit. Notamment, pour répondre à l'incertitude, les firmes développent des types différents de flexibilityé portant sur la production, la technologie et la main-d'oeuvre par des moyens quelquefois innovateurs qui ne correspondent pas à des critères idéals. La démonstration est faite, de façon empirique, par un examen détaillé de plusieurs cas de compagnies de I'industrie manufacturière du bois d'oeuvre de la région du Vancouver métropolitain, en Colombie-Britan-nique.
Mots-clés: Spécialisation flexible, incertitudes du marché, industrie manufacturière du bois, stratégic de I'entreprise, Vancouver.     

Wicked game of smart specialization: a player’s handbook

The objective of this article is to explore the theoretical foundations of a wicked game. The theoretical part is based on the notion of wicked problems, which is developed further. It is also illustrated that the latest innovation strategy of the European Union, called smart specialization, resembles a wicked game. Comparison between the two revealed several similarities gives new insights into the theory of wicked problems and into the process of smart specialization.
