Do social protests affect government housing-related decisions? If so, in what way? To answer this question this study examines the influence of Israel's 2011 social protest on the government's housing policy, using an empirical cumulative-aggregative analysis of housing-related decisions over the past two decades. The empirical analysis is based on two generic classifications of government interventions commonly used in housing literature: first, decisions aimed at increasing the housing stock (supply-side), as opposed to policies aimed at augmenting consumers' financial capacity to obtain adequate housing (demand-side); and second, decisions that encourage homeownership as opposed to those that promote rental housing. The research findings show that the 2011 social protest definitely affected Israel's housing policy, because it prompted the government to engage in housing. However, the interventions introduced focused largely on increasing the inventory of housing units (supply-side) for homeownership and benefited mainly members of the middle class who qualify for mortgages and investors. Thus, despite the increase in government involvement in the post-protest period, Israel's housing policy has remained neoliberal, though in an advanced form of neoliberalism that combines market-oriented policies with centralized tendencies, which we call “centralized neoliberalism.” The study discusses the findings and their implications for various population groups. Given the current global affordable-housing crisis, the findings are relevant to many countries whose existing neoliberal housing policy is failing to address housing-market problems and challenges.  相似文献

The results obtained from the multi-analytic compositional characterization of ceramic pastes and paints of the Santa María style, from the El Bolsón valley (Belén Department, Catamarca Province, Argentina), are presented here. This pottery style had a wide regional distribution in Northwestern Argentina between ca. 1000 and1600 ce and is characterized by its complex iconography painted in black, cream and red. The analyses show that the containers correspond to the technical tradition of using grog temper and suggest that its manufacture involved a double firing process. This reveals a new practice for the time.  相似文献

Tel Megiddo is a major type-site for the Middle Bronze in the Levant. During this period a new burial custom appeared in which the dead were interred beneath occupied houses. This tradition is well attested in Area K at the site. Area H, near the palatial complex, revealed a monumental masonry-constructed chamber tomb. This article presents the results of residue analysis conducted on ceramic vessels placed in these tombs as burial offerings. Hundreds of intramural Middle Bronze tombs with ceramic offerings were excavated in the Levant, but this is the first time the content of the vessels is revealed.  相似文献

Research into the family of the Counts Swéerts-Sporck raised doubts regarding their biographical data, particularly concerning a child who died in 1817, later identified as Philipp Swéerts-Sporck, and his siblings Joseph and Barbara. These were alleged to include a pair of dizygotic twins, but DNA could not be used to clarify their relationships. Carbon and nitrogen isotopes were therefore measured in their first permanent molars, whereas Philipp's biological age was estimated based on his skeleton. Philipp died at an older age than the written sources claim; an isotopic similarity was found between Joseph and Barbara, but Philipp differed.  相似文献

Critical physical geography (CPG) calls for integrative research on material landscapes and the socio-political dynamics of scientific knowledge production. Network analysis, a rich tradition of tools and approaches for analyzing relational information, has seen little use in the CPG literature to date. This represents a fruitful opportunity, as many of CPG's core interests—knowledge politics, histories of scientific concepts, and ecosocial relations—can be effectively analyzed using network techniques. In this article, I argue for adapting network approaches to CPG. First, I provide an overview of various network concepts, approaches, and their origins. I then discuss bibliometric network techniques for “science mapping” including co-word, co-authorship, and citation analyses. Next, I describe discourse network analysis, a recent mixed-method approach from political science. Finally, I discuss overlaps with emerging approaches from qualitative and visual network analysis. In each section, I provide existing and hypothetical examples, as well as software and visualization techniques, that demonstrate how network approaches could add new insights to CPG and related scholarship. Linking CPG with the diverse traditions of network analysis has the potential to produce new empirical understandings and bring the field into conversation with a growing body of research that spans the social sciences, natural sciences, and humanities.  相似文献

Cooling centres provide respite, safety, and social support during extreme heat events for populations that do not have the resources to own or operate in-home air conditioning. The objective of this study was to measure the spatial accessibility of cooling centres and analyze the associations between cooling centre access and marginalization in Montreal, Toronto, and Vancouver, Canada. The potential spatial accessibility of cooling centres within a 15-minute walk was measured at the dissemination area scale using the two-step floating catchment area method. A two-stage modelling approach was used to analyze the associations between cooling centre access and marginalization. Approximately 62%, 58%, and 54% of the populations in Montreal, Toronto, and Vancouver had access to at least one cooling centre. In Montreal and Vancouver, high marginalization areas were more likely to have cooling centre access than low marginalization areas. Of the areas with cooling centre access, smaller access scores were observed in areas with high residential instability. Approximately one-fifth of the areas in each city had no cooling centre access and high marginalization, and may be considered for future cooling centres or programs that improve accessibility to existing centres.  相似文献

Monitoring is deemed crucial for the incentivization of a decentralized organization, but its function relies on information transparency between the central authority and the delegated individuals. We test this hypothesis by considering changes in the fiscal behavior of Chinese county governments following an exogenous fiscal reform in 2004/2005 that removed information obstacles between provinces and counties. Employing data on 590 Chinese counties from 2000 to 2009, we find that counties in the reform provinces adopt a more proactive fiscal policy after the reform, suggesting that they become more incentivized in the political competition for economic growth. Such effects are stronger in counties with fewer competing peers and counties with either high or low ranks in the records of economic growth among peers. The increase in counties' productive spending leads to higher economic growth in later years.  相似文献

This study aims to provide a comprehensive examination of the evolution of regional science, a scholarly domain in the social sciences that applies analytical and quantitative approaches and methods to understand and address urban, rural, or regional problems. We conducted a bibliometric analysis of 8509 articles published in six regional science flagship journals (including the Journal of Regional Science, Annals of Regional Science, Regional Science and Urban Economics, Papers in Regional Science, Regional Science Policy and Practice, and International Regional Science Review) from 1958 to 2021. The analysis presents an objective data-driven and unprecedented visualization of the field's intellectual, social, and conceptual structure and trends from the beginning to the present. It also provides a rich portrayal of the epistemology of regional science and illuminates matters related to regional science education and training. We find that regional science has moved well beyond its origins, shifting away from a heavy focus on theory and abstraction to modeling/simulation, empirical analysis, and policy research. We also find that there has been increasing attention to “people” in regions and the spatial characteristics of social problems, and some important shifts in the regional science community itself, particularly in terms of patterns of collaboration and the geography of scholarship. The findings of this paper provide implications for future directions of research and education for regional science.  相似文献

The Narrative Policy Framework (NPF) suggests that narratives can be employed to define and contest policy problems. Yet, few NPF studies have explicitly addressed the narrative portrayal of problem intractability. What role do narratives play in a situation of uncertainty about the causes and solutions of the problem, when strong divergences regarding the values and interests of the policy actors exist? The article anchors the NPF to the literatures on problem definition and implementation to advance two propositions about (a) how differences in the use of narrative elements can be suggestive of the degree of problem (in-)tractability; and (b) whether other elements of tractability, namely the presence of a valid causal theory, are associated with the usage of narrative strategies. I test the propositions by analyzing media commentaries surrounding the implementation of European decisions to tackle a tree-killing epidemic in Italy. The findings suggest that narratives can helpfully illustrate the intractability inherent in the policy debate. However, narratives can also develop independently of factors that the implementation literature understands as conducive to lowering intractability, namely knowledge accumulation. The NPF may represent a promising alternative to understand policy implementation processes.  相似文献

Financial inclusion is a leading driver of household debt across the global South. Although critical geographers have analysed this debt through the lens of financialisation, few have examined it in terms of monetary politics. This is a salient issue, because poorer nations often have limited control over their monetary policy due to their dependence on foreign currencies, which can adversely affect the structure of their financial markets. Building on the concept of monetary dependency from scholarship on financial subordination, I analyse the monetary politics of debt in Cambodia. Drawing on elite interviews and ethnographic research, I argue that Cambodia's extreme monetary dependence on the US dollar has shaped monetary and fiscal policies that compel poorer households to take on private debt to pay for their basic needs. This paper advances critical geographies of debt and development by studying financial subordination and its impact on financial inclusion in the global South.  相似文献
