Lithic researchers rely heavily on experimentation to infer past behaviors and activities based on stone artifacts. This paper explores the analogical nature of archaeological inference and the relationship between experimental design and inference validity in stone artifact experimentation. We show that actualistic flintknapping lacks vital aspects of scientific experimentation, and thus has inherent inferential issues of analogical adequacy and confidence. It is argued that a greater emphasis on hypothesis construction and variable control is needed in order to establish sound referential linkages upon which constructive analogic inferences about the past can be built.  相似文献

It is well established that digital technology and code mediate bodies in space. The collapse of any supposed physical/digital divide has been amply documented to the extent that everyday life is now widely theorised in terms of hybridisation. What is less clear is what comes next for those participating in this hybridisation. This article examines what Kitchin and Dodge term the ‘social contour of software’ via queer male locative media users who collectively negotiate digital hybridisation in their everyday lives. Using qualitative interviews with 36 non-heterosexual men using apps such as Grindr and Tinder in London, UK, I explore how locative media refigures conceptualisations of community, technological efficiency and boundaries between private and public space. The study finds that users express ambivalence about their membership of queer ‘communities’, and are also unconvinced by online sociality. Apps expedite searches for new partners but prove deceptively time-consuming. Public and private space are being hybridised by locative technology, but common codes of conduct are slower to develop, leaving users unsure of how to navigate physical encounter. This article concludes that schema for queer men’s lives are increasingly promulgated digitally but may be uneasily embodied in everyday practice.  相似文献

An Approach toward Energy Balance Simulation over Rugged Terrain   总被引:1,自引:0,他引:1  
We develop a digital computer model, based upon equilibrium temperature theory, of the magnitudes of the components of the energy balance for a mountainous topographic surface. The model includes an algorithm for calculating slope, exposure, and horizon information for every point on a digitized grid. Incoming solar and thermal radiation are then simulated for every point. At present the model is designed for clear-sky conditions, but it could be modified for cloudy skies. Air temperature and humidity variations are specified by externally defined relations, and values for albedo and soil thermal properties are specified for every point on the grid. Wind speed variation over the grid is not modeled, but is specified by an empirical function. The model simulates net radiation, soil heat flow, sensible and latent heat flow, and surface temperature at specified time intervals. Output is in the form of contour maps.  相似文献

New Zealand has some of the most active areas of rhyolitic volcanism in the world and this has produced numerous obsidian sources in the northern half of the North Island. In total archaeologists have recognized 27 named locations from which obsidian can be obtained scattered across 4 geological source regions. Shortly after colonization in the late 13th century AD Polynesian settlers began transporting this material some thousands of kilometers throughout the country and across the sea in small quantities to distant neighbors in the Kermadecs and Chatham islands. Although considerable research has been conducted on obsidian sourcing in New Zealand the complexity of geochemical source discrimination and the lack of a practical method of non-destructive geochemical analysis has hindered progress. We present the results of our use of PXRF to provide geochemical data on New Zealand obsidian sources and to compare the use of discriminant analysis and classification tree analysis to discriminate among sources and attribute archaeological samples to sources. Our research suggests that classification tree analysis is superior to discriminant analysis in sourcing studies. A large case study using an important settlement phase site (S11/20) from the Auckland region demonstrates the utility of the methods and the results support a model of high degrees of mobility and interaction during the early settlement of New Zealand.  相似文献

The “concealed communities” of our title are the people archaeologists have often labeled as “marginal.” Archaeologists writing about both prehistoric and historic periods have commonly made a range of assumptions about margins and marginality, and their discussions have often categorized marginality as ecological, economic, or socio-political. Whilst it has been common to privilege one or other of these categories in order to explain how societies worked, they are rarely mutually exclusive. In addition, since marginality is relative, virtually any group might be made marginal depending on people’s perspectives in the past or present. Sometimes marginality can be imposed (economically or politically), and sometimes even actively chosen. Defining the “margin” is a complex business, and the term needs sensitive, context-orientated use to make it useful for archaeologists.  相似文献

The growing influence of neoliberal approaches to environmental governance has significantly increased the involvement of industry non-state actors in international and national climate governance. However, the implications of this neoliberalisation and hybridisation of climate governance, and particularly state–industry relations during these processes, remain under-integrated with wider geographical debates on the scalar and network politics of environmental governance. In this paper, we probe these issues by examining the regulatory and territorial logics underpinning the negotiation and implementation of the European Union emissions trading scheme (EU ETS). We argue that overlapping interpretations of the regulatory logic of emissions trading (as a cost-effective means of meeting climate objectives) by EU, state and industry actors provided the driving force for the creation of a Europeanised climate governance space and the consolidation of the EU's governing authority in respect of the formal rule-making elements of the EU ETS. However, alliances between state and industry actors, based around intersecting interpretations of their territorial interests in relation to emissions trading, strongly influenced the scheme's design. Moreover, speculative behaviour within the EU ETS market indicates the continued ability of market networks to disrupt territorially-based climate governance regimes. We argue that critical exploration of the territorial logics and practices of EU emissions trading from regime creation to operation provides new insights into the emerging spatial politics of neoliberal environmental governance and its implications for climate protection.  相似文献
