While many studies have examined human impacts on prehistoric environments, few have explicitly examined how foragers adapt to the changing environmental situations that they have created. The goal of this analysis is to study the relationship between human foraging economies and human-related environmental change in southern New Zealand. Foraging theory is used to generate predictions about subsistence change resulting from the declining abundance of important resources such as moas and seals. In particular, these predictions examine changes in (1) the kind of resources exploited (foraging efficiency), (2) the number of resources utilized (diet breadth), and (3) the habitats exploited (patch choice). The predictions are tested using the large assemblage of vertebrate faunal remains from the well-stratified and well-dated Shag River Mouth site. This study shows that using foraging theory models to structure analysis provides a more fine-grained spatial and temporal resolution of subsistence change in southern New Zealand than has been previously achieved. 相似文献

Compared to most other advanced democracies, Australia experiences fairly high levels of both intentional and unintentional informal (or invalid) voting. Using survey data obtained predominantly from the Australian Election Study and aggregate-level data derived mainly from the Australian Census, we explore whether young people are more likely to cast intentional informal votes. We also reflect on why they might do so. We find that young people are strongly implicated in the rising intentional informal vote rate. We also find that their motivations are linked to the following factors: the young are less likely to be members of political parties, less interested in electoral politics and tend to value voting less than the average citizen. Young people also report higher than average levels of cynicism about politics and lower levels of satisfaction with Australian democracy. 相似文献

This paper reviews recent archaeological research concerning Classic Maya lowland political systems (ca. A.D. 250–1000). It focuses specifically on (1) subsistence practices revealed through the analysis of prehistoric climate, available resources, agricultural technologies, and diet; (2) population distribution, density, and size revealed through the analysis of settlement practices and architectural function; (3) social differentiation and interaction revealed through the analysis of burial practices, diet and health, architecture, and production, consumption, and exchange patterns; and (4) ancient Maya political economy (how it was funded) revealed through the analysis of community organization, ritual activities, the Classic Maya collapse, and warfare. It finally ends with a brief discussion of the future of Maya archaeology. A key factor that recurs throughout this review is the noticeable amount of variability that existed—varied resources, subsistence strategies, settlement practices, and social and political systems. An understanding of this variability is the key to appreciate fully the Classic Maya. 相似文献

The United Nations World Social Report (2020) reveals that more than two thirds of the world's population live in countries where urban inequalities have increased in the last three decades. While urban inequalities are traditionally characterized as an economic issue, scholars are increasingly applying methods from geospatial analysis to study them. In the context of these advancements, it remains unclear what underlying perspectives are guiding decisions to concentrate on certain aspects of urban inequalities, while potentially ignoring others. We address this gap by reviewing the literature centered on the geospatial analysis of urban inequalities and identify three predominant research lenses from accessibility, distribution, and policy and stakeholder perspectives. As a primary contribution of this article, we connect the perspectives with ideas drawn from complexity theory to develop an overarching socio-technical framework for how urban inequalities emerge over space and time. While traditional scientific frameworks seek to increase knowledge through causality, complexity science acknowledges the inherent challenges in defining, understanding and solving complex problems such as urban inequalities, which has profound implications for their representation, modeling and interpretation. We critically reflect on the framework through key relational themes and insights drawn from the literature and close with considerations for future research. 相似文献

Photography as Science: In 1908 the English physicist Arthur Mason Worthington published A Study of Splashes, a treatise on the physical behaviour of falling drops. The photographic experiments were performed by means of an electric spark „in absolute darkness”︁. Worthington's experimental practice dealt with two different areas of knowledge production: an area the operator could perceive control from the outside and a corresponding black-box where the photographic recording itself took place. The paper discusses the epistemic challenges of this specific shift from imperceptible events to their photographic representations. It shows to what extent the information revealed by the photographic apparatus had to be converted, for it did not speak for itself. Thus, Worthington's work went beyond the classical dichotomy between objectivity and imagination. 相似文献
