Key trends link a globally connected urban archipelago and its hinterlands, warranting new studies of power in its most contemporary forms. This article locates land power and where that power is exercised – looking at the burgeoning global land rush from the perspective of cities. Urbanisation continues to drive vast political transitions, uprooting longstanding agrarian modes of living while creating myriad inequalities within cities. Are the world’s most powerful agglomerations active agents in this transformation? Answering affirmatively, the article reframes urbanisation as a vast, global geopolitical transfer of power from rural to urban. Leading global cities like New York, London, Hong Kong, Chicago and Singapore are not merely impressive collections of factor endowments. They are also sites of concentrated power with coercive influences beyond municipal boundaries. The article asks how cities project power in the contemporary global system. Juxtaposing data on global connectivity with the location strategies of private firms, we learn that the world’s most successful global cities are also sources of exploitative accumulations of land. 相似文献

This article explores the role of Queensland voters in the 2019 Australian federal election. The article identifies five key elements of a Queensland political culture before offering evidence that the Liberal-National Coalition's exceedingly strong performance in Queensland in 2019 was not a single aberration, but one of a long and continuing pattern of electoral nonconformity. The article also argues Queensland's complex regional diversity necessitates analysis across not one or two constituencies but via six geographically, economically and demographically diverse regions. Third, the article argues the unexpectedly large swing against the Australian Labor Party in Queensland in 2019 was fuelled, overwhelmingly, by five factors, each consistent with the five core elements of a Queensland political culture. 相似文献

This article employs the concepts of security culture and normlocalization to explore some of the cultural dimensions of theAfrican Union's (AU) security policies. After providing an overviewof constructivist accounts of norm socialization in internationalrelations, I use these insights to analyse the origins and developmentof the AU's security culture. The final two sections explorethe ongoing process of norm localization in relation to thetwo most recent tenets of the AU's security culture: intoleranceof unconstitutional changes of government and the responsibilityto protect principle. An awareness of the uneven and contestednature of this process helps account for the fact that althoughthese two transnational norms have been institutionalized inthe AU Charter and endorsed by the United Nations, they havebeen internalized unevenly by the AU's member states. Externaladvocates of these two norms would thus do well to help thecontinent's norm entrepreneurs build congruence between thesenorms and the AU's security culture. 相似文献

This study presents a number of pseudo-operational trials on plastic bags investigating the double- and co-fuming process of a one-step fluorescent cyanoacrylate (LumicyanoTM) in comparisons with the two-step process with basic yellow 40 (BY40) staining for the detection of latent fingermarks. The results demonstrate that both Lumicyano solution and dye contribute to the increased detection of latent fingermarks during the double-fuming process (trial 1). Co-fuming the Lumicyano solution and dye separately (at a concentration of 8%) but simultaneously was less effective than 8% Lumicyano (trial 2). Co-fuming Lumicyano 8% and an additional 8% Lumicyano dye by weight was more effective than Lumicyano 8% (trial 3), possibly due to increased fluorescent material deposition during co-fuming allowing for better visualization. The use of BY40 after Lumicyano resulted in a considerable increase in detected fingermarks. 相似文献

Forensic Technicians provide crime scene investigation services and are exposed to stressful violent crimes, motor vehicle accidents, biological or chemical hazards, and other appalling imagery. Forensic Technicians would likely experience physical and psychological stress after exposure to trauma, and security vulnerabilities similar to Sworn Police Officers. The perceived availability of mental health resources, job-related physical, psychological stress, and traumatic experiences of both Forensic Technicians and Sworn Police Officers from California law enforcement agencies were investigated using a self-reported survey. Responses were evaluated for any significant differences in the perceived stress, job-related physical stress, and resulting psychological impact affecting the participants. The survey contained a mix of True/False, Circle/Check the Appropriate Box, or Likert Scale (1–5) responses. The results were evaluated statistically and discussed. Results indicated Sworn Police Officers and Forensic Technicians have different on-duty stress levels, but similar off-duty stress levels. Nearly two-thirds of 54 job-related stressors were not significantly different between the two occupations. However, Forensic Technicians reported more adverse effects in 17 physical and psychological job-related activities compared with Sworn Police Officers. Forensic Technicians reported lower awareness levels and availability of agency mental health support services than were reported by Sworn Police Officers. This study reports for the first time an unexpected outcome that perceived and job-related psychological stress is greater for Forensic Technicians than Sworn Police Officers. Possible reasons for this disparity will be discussed as well as stress management tools that should be implemented to reduce health risk factors for both career professionals as well as increase public safety. 相似文献

Motivational interviewing (MI) is a communication style focused on enhancing clients’ own motivation towards change. In the justice system MI has evidence to support that it enhances communication and change behaviors in youth. As most MI training is designed for healthcare settings training and implementation of MI must be adapted to fit the juvenile justice model. This includes both rehabilitation and restorative justice. Here we describe the details that allowed one county small county in Pennsylvania to roll out MI training and initial skills review in less than 6 months. The case reviews the details of planning, trainings, and timing of activities. We then discuss what elements of those details fit into a greater implementation plan that may be applied elsewhere. Four key elements were instrumental to implementation: 1) appreciation of JPO time constraints, 2) cost containment 3) using blending to enhance JPO flexibility with MI use, and 4) policies that normalize use of MI. This outline may assist other courts in their own implementation efforts. 相似文献

African agriculture is often dominated by smallholder farms composed of multiple plots. In policy circles it is often assumed that fragmentation coupled with small farm size is an impediment to increasing yields and thus decreasing poverty and food insecurity. There also exists an influential literature that explores the inverse relationship between farm size and yield. While there are many studies internationally, few have been conducted in Africa. Using an Ethiopian national survey, we explore the relationship between yield, farm size and fragmentation. We find an inverse relationship between farm size and yield, and a positive association between yield and land fragmentation. 相似文献
