The institutional landscape for public land management in the U.S. West underwent a seismic shift in the 1990s as the long‐dominant resource extraction paradigm was replaced by the ecosystem management paradigm. Here we analyze the efforts of community‐based organizations (CBOs), entities that emerged in some locations across the West to help their respective communities navigate the transition from resource extraction to environmental stewardship. Despite their formal status as civil society actors, in practice CBOs came to fill various institutional gaps by taking on roles traditionally assigned to both the state and the private sector. We use a case study approach to examine how the Hayfork, California–based Watershed Research and Training Center engages in institutional work within a setting that is at once both open and constrained, as the rural community within which it operates lacks strong state‐ or industry‐led development trajectories while remaining constrained by the legacies of past institutions. 相似文献

The growing backlog of immigrant visa petitions and legal permanent resident adjustment applications is a harsh reality of the American dream. Dependent children of immigrants can wait decades for their parents' visas to become current, only to age out of dependent status before stepping foot on American soil. Dependent children of nonimmigrants seeking to become legal permanent residents age out before their parents' adjustment application is approved – leaving them at risk of removal. This Note proposes a temporary visa status for these dependents, allowing them to maintain legal status in America and remain with their parents. 相似文献

Recent research has revealed that misinformation from gestures can influence eyewitness memory. However, it is still unclear whether gestural misinformation can emulate the effects of verbal misinformation on the reporting of major details in serious crimes. To investigate the salience of suggestions provided nonverbally, and how these compare to those made verbally, two experiments were conducted. In Experiment 1, participants watched footage of a crime scene and were presented with one of two types of gestures during questioning that suggested different interpretations of the crime. The results confirmed that the gestures influenced responses, with participants altering their interpretation of the crime according to the information gestured to them. Experiment 2 built on this to investigate how comparable gestural influence was to verbal influence. The results revealed that gestural misinformation caused participants to alter their interpretation of the crime and elicited the same effects as verbal misinformation. Across the two experiments, participants were unlikely to identify the misleading gestures or report feeling misled by them. These results reveal new insights into the strength of gestural misinformation and show that, despite their subtle nature in communication, gestures can exert a powerful influence in eyewitness interviews. 相似文献

Cyberterrorism is an increasingly pervasive term in the mainstream media; however, its definition remains vague at best. As the use of information technology continues to expand, the real and virtual worlds are evermore entwined, including the use of such technology for military purposes. Contemporary work in border studies explains the growing permeability of state borders. Inspired by the works of Paul Virilio, this paper holds that cyberattacks exemplify the increasingly relational quality of war. Case studies of China, Iran, North Korea, Syria and Russia are offered to illustrate this trend. 相似文献

Subnational Responses to Fracking in Canada: Explaining Saskatchewan's “Wild West” Regulatory Approach

This article assesses the regulatory response to fracking by Saskatchewan, Canada's second largest oil‐producing province. Public officials and industry representatives claim fracking regulations are “comprehensive” and “robust”; however, there has been no comparative assessment of this claim. To address this gap, we outline the dominant regulatory pathways of U.S. states and Canadian provinces, ranging from applying existing regulations with minimal revisions, to enacting broader revisions or bans. We account for this variation using a framework from Davis ( 2012 ) emphasizing governments’ dependence on the oil sector, the level of support for fracking among elected officials and policy makers, and the influence of key “constituencies.” The article then traces the growth and impact of fracking in Saskatchewan and analyzes new trends in the province's regulation of fracking. Given the province's application of existing regulations with minimal revisions and active weakening of enforcement, we identify Saskatchewan as taking Rabe and Borick's ( 2013 ) “conventional” regulatory approach, typical of Davis's “energy dominant” states. 相似文献

As police officers have become increasingly common in U.S. public schools, their role in school discipline has often expanded. While there is growing public debate about the consequences of police presence in schools, there is scant evidence of the impact of police on student discipline and academic outcomes. This paper provides the first quasi‐experimental estimate of funding for school police on student outcomes, leveraging variation in federal Community Oriented Policing Services (COPS) grants. Exploiting detailed data on over 2.5 million students in Texas, I find that federal grants for police in schools increase middle school discipline rates by 6 percent. The rise in discipline is driven by sanctions for low‐level offenses or school code of conduct violations. Further, I find that Black students experience the largest increases in discipline. I also find that exposure to a three‐year federal grant for school police is associated with a 2.5 percent decrease in high school graduation rates and a 4 percent decrease in college enrollment rates. 相似文献

Two hundred prosecuting attorneys completed a survey concerning priorities in taking on animal cruelty cases and the factors that help or hinder prosecuting such cases. Respondents commented on the priority given such cases. Questions also addressed specific kinds of evidence that had been used to decide whether to take on a cruelty case and were used in court. Results showed that prosecutors most frequently relied upon “traditional” sources of evidence, including detailed medical and crime scene reports and good quality photographic evidence. Other sources of forensic evidence such as DNA, computer forensics, forensic accounting, blood, and trace evidence were rarely employed. Veterinary forensic evidence, including forensic necropsies and detailed medical reports, was viewed as an important factor by a majority of prosecutors in deciding whether to accept a case for prosecution and in achieving a successful outcome, but a need for additional training for investigators was indicated. 相似文献
