This paper examines how tourism as a form of land use and economic development is a critical site of struggle over the meaning of neoliberalism, landscape and land rights in northern Tanzania. I examine two tourism arrangements in Loliondo: joint ventures between expatriate-owned ecotourism companies and predominately Maasai villages; and the leasing of a hunting concession on village lands by the central government to a powerful foreign investor from the United Arab Emirates. Despite the fundamental role of foreign investors in appropriating resources and surplus value from regional landscapes in each of these cases, I argue that the Maasai in Loliondo see contemporary land grabbing as firmly situated in state claims to property and territory. The Maasai in Loliondo have come to think of the market, expressed through their direct relationships with ecotourism investors, as the most promising space to legitimize and secure land rights and access to resources. Loliondo, an area in northern Tanzania bordering the Serengeti National Park and the Ngorongoro Conservation Area, has become one of the most important sites for tourism development in Tanzania. This region is home to the iconic Maasai people, who practice pastoralism and are part of what attracts tourists to Tanzania. These Maasai face increased pressure to assert their local vision of a landscape and their ability to commoditize it. I situate current land struggles within the political economy of tourism in Loliondo and show how different articulations of market–state–community become both materially and symbolically meaningful. Ultimately, I argue that the Maasai retain faith in market-based relationships in spite of increasingly limited room to maneuver.  相似文献

The effectiveness of latent fingerprint development techniques is heavily influenced by the physical and chemical properties of the deposition surface. The use of powder suspensions is increasing for development of prints on a range of surfaces. We demonstrate that carbon powder suspension development on polymers is detrimentally affected by the presence of common white pigment, titanium dioxide. Scanning electron microscopy demonstrates that patches of the compound are clearly associated with increased levels of powder adhesion. Substrates with nonlocalized titanium dioxide content also exhibit increased levels of carbon powder staining on a surface‐wide basis. Secondary ion mass spectrometry and complementary techniques demonstrate the importance of levels of the pigment within the top 30 nm. The association is independent of fingermark deposition and may be related to surface energy variation. The detrimental effect of the pigment is not observed with small‐particle reagent (MoS2 SPR) or cyanoacrylate (superglue) fuming techniques that exploit different development mechanisms.  相似文献

This article makes a comparative analysis between the Spanish and Brazilian Urban Law, from the perspective of territorial and urban planning. Taken the basis of the constitutional rules that distribute powers to public authorities of both countries, and also the main laws that regulate the matter, as the case of RD 2/2008 of 20 June, approving the revised Land Law (TR/08, in Spain) and the Statute of the Cities (Law No. 10.257, f June 21, 2001 in Brazil). Besides that, highlight some differences between countries, such as the structure of the States —Spanish Parliamentary Monarchy and Brazilian Federal Republic— that is not an impediment to enable countries to use the legal constructions of the other country to improve its own system, especially in the metropolitan issue.  相似文献

Purpose

This study analyzes the stock price impact of the Aurora theater and Newtown (Sandy Hook) school massacres on both domestic (US) and foreign theater operators and US gun manufacturers in an effort to document the economic effects of these tragedies.

Methods

The well-established “event study” methodology from the fields of economics and finance is employed to assess the impact of the shootings on the affected companies after controlling for risk and overall market movements.

Results

The Aurora theater shooting resulted in striking declines for Cinemark (the targeted theater) as well as major US competitors, but had no impact on overseas theater chains. Smith & Wesson (maker of the gun used in Aurora) showed no response, whereas Ruger (a competitor) exhibited large gains. Both Smith & Wesson and Ruger plunged after the Newtown shooting, although neither made the weapons used in the shooting.

Conclusions

Contrary to prior research on workplace homicides, the results show that random mass shootings have profound effects on targeted companies. In addition, the results suggest the presence of a very strong “contagion effect” (where negative events affecting one company impact others in the same industry). The negative responses of both publicly-traded US firearms manufacturers to the Newtown shooting suggests a “sea-change” in the debate over gun ownership in the US.  相似文献

Abstract

The backbone of Dutch criminal procedure is the case file including a large number of written records. In Dutch courts the focus is primarily on evaluation of written records. The written record of police interrogation is a mediated account of the interrogation itself. In this study we explore how individual differences in the production of written records by police officers affect the jurists' evaluation of the suspect's story and of the quality of the interrogation itself. In the first study, five police officers produced written records of one and the same interrogation on video of a denying suspect. In the second study, three of those written records are evaluated by jurists. They are asked to determine story acceptability of the suspect and procedural fairness of the interrogation. Findings show that a short and simple interrogation of a suspect results in written records that are quite different (Study I). It is further shown that these differences affect the jurists' evaluation of some of the core issues addressed in a criminal process (Study II). Implications of these findings are discussed as well as a number of possible ways to improve the current state of affairs.  相似文献

ABSTRACT

This paper discusses the sentencing purposes for penal penalties, judges’ perceptions of sentencing purposes and prison sentences, and the effects of penal sanctions. We examine judges’ positions towards different penalties, with a focus on imprisonment, since their views on the different penalties are related to their sentencing decision-making. Understanding these views is then critical for several practical and political purposes, including bridging the gap between academic discourse and legal practice. We accessed judges’ views on penal sanctions through a questionnaire and an interview. Our sample is compounded by the judges of the criminal courts from the three major cities in Portugal. Despite the most recent criminological empirical knowledge, judges valued imprisonment as the most adequate sentence, both for different crimes and for different judicial purposes. This result is not consistent with viewing imprisonment as a ‘last resort’ solution. Indeed, we did not find this ‘last resort’ position in our data, and it is not apparent in the judicial statistics on imprisonment rates. Our data highlight the importance of increasing judges’ training on criminological and sociological issues as well as the importance of changing the influence of their personal beliefs regarding penal sanctions into research-based positions.  相似文献

The position of children in the family economy changed fundamentally from the 19th century onward. In the Netherlands, the first child labor act was introduced in 1874; compulsory schooling was established in 1901. Since then, the economic contribution to the family income by children has gradually disappeared. Until the 1960s, in working-class families, the financial contribution of adolescents to the family income remained of great importance. Young workers gave their whole wage to the family in exchange for housing, food, clothes, and some pocket money. This article describes how the economic role of teenagers has changed since then. Nowadays, children and adolescents do not contribute to the family purse any longer.  相似文献

Whereas other contributions in this volume focus on contemporary migration, this article explores the role migration has played over a long period of time, in western Bihar, India. By doing so, it reinforces one of the central themes in this volume, regarding the importance of migration for livelihoods: this case study challenges the assumption that migration would be a recent phenomenon, and argues that to understand the history of this area one needs to take account of the complex interaction between migration and development. Migration has been a livelihood strategy for many groups within the area, and the study explores how migration has been caused by and in turn influences poverty and livelihoods for men and women, and how these relationships have changed over time.  相似文献

Birth registration imposes major challenges in developing countries, with importance to rights, health and all levels of development. Despite targeted initiatives, often with focus on improved access and information, universal registration has been elusive. Using cross-sectional survey from Kenya, we provide new evidence for why parents may not register. We report high awareness, low barriers – however with over 50 per cent of children unregistered. We argue this is due to deliberate, informed choice by parents where they weigh perceived costs/benefits. We recommend new focus on this deliberation and policy piggybacking hospital delivery, vaccination and information and communications technology to re-balance parent decision.  相似文献
