In this paper, we argue that democracy is increasingly indistinguishable from authoritarianism, in a process that is entangled with neoliberalisms. To build this argument, we examine a case study of central government intervention in regional environmental decision making in Aotearoa New Zealand through the lens of Agamben's “state of exception”. The intervention—unprecedented and unconstitutional—squeezed democratic spaces for decision making about freshwater and sought to smooth the way for capital accumulation. The audacity of government actions indicate, we argue, an abandonment of efforts to disguise neoliberal encroachments on democracy, known as the double truth tactic. Yet we also argue that in identifying this as a state of exception, we can examine it as part of a process and therefore demonstrate the possibilities for counter‐hegemonic actions to emerge.  相似文献

The objective of this paper is to assess an approach to statistical modeling of point referenced establishment data that permit inclusion of “environmental” or establishment‐specific covariates and specific forms of interestablishment interaction. Gibbs models are used to decompose the conditional intensity of the spatial point process into trend and interaction components. The trend is composed of access measures (primarily different classes of roads) and three different interaction processes are tested: Geyer, area interaction, and Strauss hard core. While the models used have proved to be useful in ecology, we are unaware of any applications to establishment or firm data. In empirical application, the models yield intuitively appealing results for the trend component, and the ability to specify the interaction component gives deeper insights into interestablishment spatial dynamics than any previously published methods.  相似文献

We examine the relationship between individual commuting behavior and household responsibilities, with a focus on gender differences in that relationship. Using the Dutch Time Use Survey for the years 2000 and 2005, we analyze the relationship between commuting time, home production, and childcare. To deal with reverse causality, we use Propenstity Score Matching techniques to obtain imputed data for individuals. We find that the effect of home production on commuting time for women is more than double that for men, while childcare time has an effect on women's commuting behavior only. Our results shedding light on the Household Responsibility Hypothesis.  相似文献

Aerial photography provides a valuable recording method for archaeological sites and is often underutilized. In the past, aerial photographic platforms were expensive and often required highly specialized equipment. However, with new technology a variety of different platforms are now available. This paper will analyze two low cost aerial photographic platforms used at the Australian Archaeological Institute at Athens/University of Sydney's project at Zagora, on the island of Andros, Greece. Over two years, both kites and drones were used with relative success. Through a review of the application of both systems on the project, along with a quantitative analysis of the cost, transportability, operation and quality of photographs, the strengths and weaknesses of both platforms will be discussed.  相似文献

This article analyzes the multiscalar relationship between state violence and domestic violence among low-income residents of Cairo, Egypt. To do so, I look at the concept of care and how notions of care are intimately linked with interpretations of violence within daily life. In the accounts of research participants, acts of violence are instances that are understood as lacking regard for the other’s well-being. Violence is juxtaposed against ‘discipline’ and is generally understood as an act of care meant to correct inappropriate behavior. Here, discipline can encompass acts of physical force. Finally, findings show that for low-income Egyptians, the violence of the state not only shapes but also happens simultaneously to violence in the home.  相似文献

Methodological advancements in geoarchaeology and spatial and chronological modeling are opening new avenues to interpreting large coastal shell-bearing sites. We document the developmental histories of two such sites around Prince Rupert Harbour, Canada, using systematic percussion coring, intensive radiocarbon dating, and 3D surface mapping with Total Station and LiDAR. We also re-analyze a third site (Boardwalk/GbTo-31) excavated and radiocarbon dated in the 1960s, 1970s, and early 2000s using archival field notes, site maps, and stratigraphic profiles georectified using LiDAR. We map the natural landform beneath the sites and document the degree to which people physically modified landforms through the deposition of massive shell accumulations. We model site development through time and space and use accumulation rates and OxCal modeling to test for intentional deposition events. All three sites demonstrate complex and heterogeneous occupation histories. At each we identify instances of very rapid deposition that effectively terraced and extended parts of the natural landform to create places for constructing houses, though these episodes take place within longer histories of slower quotidian deposition. The anthropogenic modifications to the coastline in this area are the result of these mixed processes associated with long histories of occupation.  相似文献

While the links between contaminated sites and adverse effects on human health and well‐being are being increasingly recognised, some argue that the magnitude of the health problem is inadequately addressed because it is largely invisible. Health geographies literature has sought to highlight this invisibility by focusing on the link between contaminated sites and health. This study adds to health geographies by presenting unique insights into the geography of residents' worry about the disruptive effect of environmental contamination on health and well‐being. It analyses a sample of residents (n = 485) living near 13 contaminated sites across Australia. Ordinal logistic regression analysis of closed‐format survey questions was combined with coding of open‐ended survey questions to reveal the geography of residents' worry about contamination from nearby sites. First, the study explores some of the main relationships between residents, their environs, and contaminants from nearby source sites, which determines their levels of worry: residents' demographics, residents' proximity to sites, contaminant boundaries and borders, and type of contaminant. Second, the study investigates how worry affects residents' health and well‐being, ranging from effects on their personal functioning through to their sense of ontological security, which depends in part upon their perceptions of contaminants' impacts. Despite having identified a range of diverse and negative effects of worry about contamination on residents, we found that worry for contamination can also prompt coping strategies and problem‐solving, reinforcing the need for more research on this subject.  相似文献

This study seeks to advance the understanding of the utility of “soft power” by exploring the case of Qatar. The country's approach is conceptualized as “nested power” through the examination of its political strategies before and after the regional blockade in 2017. The role of soft and nested power in Qatar has already been examined through various vantage points, such as small state diplomacy, mediation, and sports. Since the blockade has been for Qatar a great strategic dilemma, examination of how it affected power dynamics reveals the salience as well as the resilience of Qatar's soft and nested power. The article will discuss the concepts of “soft” and “nested” powers and their relevance to the state of Qatar in general and it will focus in the final section on the post‐blockade period. In doing so, we also seek useful approaches, which can be compatible with, and even advance “global international relations” (IR). The movement to make IR more global and inclusive is a welcome feature of the current century, reflective of the burgeoning role of the “Global South.”  相似文献
