Often, criminal acts involving a vehicle are caught on digital video surveillance systems. While potentially useful for an investigation, the recording conditions are typically less than optimal for the extraction of key information for the identification of the perpetrator, such as a license plate. Providing the make, model and year of a questioned vehicle is a common request for examiners, to narrow the field of potential suspect vehicles. This study seeks to compare the performance of a nonpeer-reviewed make, model, and year determination between two separate groups, specifically, trained forensic image examiners and nontrained individuals. Results show that even with varied image capture conditions and quality, the trained forensic image examiners more correctly and completely identified the test group of questioned vehicles make, model, and year. 相似文献

ABSTRACTCorporate social responsibility (CSR) is an important means to address conflicts, support local development and build trust between businesses and civil society. Yet CSR often fails to live up to its ambitions and can even exacerbate conflicts between companies and communities. In this article we consider how changing CSR strategies over the past four decades between Brazilian company Vale to Norwegian company Hydro have fomented or mitigated company–community conflicts in Northern Brazil. We find that paternalistic and philanthropic approaches of Vale over time led to deep resentment and mistrust due to underdevelopment and environmental damages. Moreover, while Hydro’s more modern CSR strategies sought to deepen community engagement and build legitimacy, the company has struggled in addressing the legacies inherited from Vale and past and current civil society grievances. The case suggests that even forward-thinking CSR approaches are vulnerable to failure where they prioritise business risk over community engagement, neglect to account for past legacies in areas of operation, and fail to create a shared vision of future development. It suggests that EI companies should both understand and engage with their social and environmental impacts in the past, present, and future and create shared economic benefits in the short and long term in order to address social conflicts. 相似文献

ABSTRACTCopyright is inherently intertwined with the development of technology and none more so than the advent of the Internet and sharing technologies. More recently, social media platforms have become the latest challenge for copyright law and policy. This article builds on the literature that recognises the underlying conflict between copyright and social networking sites (SNSs); namely that the basic implication of copyright is the restriction of copying, whereas the ethos of social networking is the promotion of sharing. In particular, this article focuses on the disparity between the restricted acts of copying and communication to the public under copyright law and the encouragement of sharing on SNS Instagram. In doing so, it contextualises the debate surrounding copyright and social media and provides an understanding of the legal implications of using Instagram. As such this paper analyses (1) the infringement of copyright protected work on Instagram, and (2) the user-agreement and licensing of copyright material on Instagram. This study concludes that the disparity between the principles of copyright and social media lead to confusion and vulnerability of users. Therefore, it is suggested that Instagram should better inform its users of the implications of sharing third-party content as well as the terms of its user agreement. This could be done by implementing a copyright strategy, which includes a notice and takedown system as well as investing in producing educational content for users. Perhaps SNSs, such as Instagram might be more motivated to take steps to recognise intellectual property rights if they were considered Internet Services Provides such as YouTube. 相似文献

Sport's transformative potential is known to support marginalised children, to deal with traumatic experiences and instil positive values; yet hosting mega sporting events (MSEs) can have negative impacts. Drawing on participatory research with favela‐based children during the 2014 World Cup in Brazil, this article argues that MSEs bring a macro‐securitisation of urban life, which causes considerable harm. This paper also suggests that the inclusion of children's voices in advocacy debates can challenge top‐down securitisation and might allow MSEs to foster further positive social transformation. Therefore, juxtaposed with causing harm, macro‐securitisations can open opportunities for children to take action and have their voices heard. 相似文献

Brazil's Movimento de Trabalhadores Sem Teto (MTST, Homeless Workers' Movement) has grown dramatically in recent years. This growth was partly provided for by the use of a large government housing programme, Minha Casa Minha Vida (MCMV, My House My Life), which allowed the MTST to construct housing for its members and swell its ranks with thousands of new members. Yet some have argued that the MCMV programme used by the MTST may compromise the autonomy of civil society organisations. This article, by contrast, argues that while the MCMV programme encouraged bureaucratic practices, it also helped to promote the cultural politics of the MTST. 相似文献

AbstractIn a crisis, aid providers deliver humanitarian relief across a hierarchy of organisations where influence and capacity map to their scale of operations. On the front lines of crises, ‘citizen aid’ is what small, local and informal groups offer to fellow citizens. These citizen aid groups are well-networked in place and tend to work through longstanding personal relationships. In the Philippines, citizen aid groups frequently support their activities by documenting their work with photos of beneficiaries to solicit donations from within the country and around the world across social media platforms. This paper builds on recent debates on brokerage through a case study of citizen aid in the relief effort after Typhoon Haiyan (2013–2017). Using this case-study approach, we demonstrate how social media has produced novel forms of brokerage shaped by circulating images online. This new kind of brokerage involves a layered network of brokers that both shapes citizen aid efforts and creates new channels for localising aid, enhancing the control of citizen groups in the Global South over aid. 相似文献

从党的政策表述及当前实践来看,基层社会治理格局的形塑过程蕴含着“党建”与“共建”的双重逻辑。“党建”的出发点是巩固党的组织优势和执政基础,表现为基层组织体系从“有形覆盖”走向“有效覆盖”,进而为引领基层社会治理准备条件。“共建”要求探索“一核多元”的治理模式,既要实现基层党组织对“共建”力量的联结和协调,也要保障多元治理主体的有效参与,同步推进群众自治、社会共治和公共服务。“党建”与“共建”的双重逻辑呈现,亦关联着社会治理研究范式的更新。 相似文献

This paper draws on recent research examining feminist and everyday geopolitics to focus on the relatively neglected domestic sphere as a space where geopolitical events like the Falklands/Malvinas war are learnt, (re)produced, remembered and contested by young people. It presents qualitative data drawn from interviews with young people from Argentina (Río Gallegos) and the Falkland Islands (Stanley), locations with intimate connections to the 1982 war. It argues that research in domestic environments that engages the familial relations, objects and practices that embody geopolitical pasts can help make sense of how young people (are able to) express geopolitical agency. 相似文献

The present study uses data on the processing of felony defendants in large urban courts to examine Hispanic, black, and white differences at the pretrial release stage. The major finding is that Hispanic defendants are more likely to be detained than white and black defendants. And, racial/ethnic differences are most pronounced in drug cases. In fact, Hispanic defendants suffer a triple burden at the pretrial release stage as they are the group most likely to be required to pay bail to gain release, the group that receives the highest bail amounts, and the group least able to pay bail. These findings are consistent with a focal concerns perspective of criminal case processing that suggests Hispanics as a newly immigrated group are especially prone to harsher treatment in the criminal case process. 相似文献
