论数码照相在刑事技术领域中的应用 总被引:1,自引:0,他引:1
李耀群 《云南警官学院学报》2001,(3):92-94
数码照相是近十年来新兴的现代摄影技术 ,具有传统摄影技术不可比拟的优点 ,目前 ,已广泛应用于刑事技术领域中的证件照片、刑事现场照相、尸体辨认照片、模糊图像信息处理、照片资料存档等各个方面。至于在记录常规痕迹物证方面 ,尽管业内一部分人士尚存有惟恐“照片失真”的担心 ,但只要制定出严格的行业标准 ,借以规范痕迹物证数码照相的操作 ,就能够趋利避害 ,充分发挥数码照相的优势 ,使数码照相在刑事技术领域中发挥越来越大的作用。 相似文献

This article explores how certain presuppositions govern our interpretations of this canonical text by Octavio Paz. I trace its biographical and textual origins, the book's peculiar reception, some of its multiple intellectual sources, and the problem of genre and how these hermeneutic discourses and epistemological tools interact. Structure (the relationship between psychology and history), rhetorical strategies and central symbols and metaphors that give the book its unity and complexity are also discussed. I conclude that we can read this hybrid work simultaneously as essay, narrative text, autobiography and modern epic myth: it is both an analytic or ironic deconstruction and an imaginative, symbolic construction of individual and collective identity. 相似文献

Self‐driving cars (also known as driverless cars, autonomous vehicles, and highly automated vehicles [HAVs]) will change the regulatory, political, and ethical frameworks surrounding motor vehicles. At the highest levels of automation, HAVs are operated by independent machine agents, making decisions without the direct intervention of humans. The current transportation system assumes human intervention though, including legal and moral responsibilities of human operators. Has the development of these artificial intelligence (AI) and autonomous system (AS) technologies outpaced the ethical and political conversations? This paper examines discussions of HAVs, driver responsibility, and technology failure to highlight the differences between how the policy‐making institutions in the United States (Congress and the Public Administration) and technology and transportation experts are or are not speaking about responsibility in the context of autonomous systems technologies. We report findings from a big data analysis of corpus‐level documents to find that enthusiasm for HAVs has outpaced other discussions of the technology. 相似文献

Studies show that women and girls consistently demonstrate higher levels of concern for the environment than men and boys. Separately, research also indicates that women officeholders pay particular attention to the issues prioritized by their female constituents. Interestingly, despite the consistency of the gender gap in attitudes to environmental issues the literature has paid scant attention to the role of women officeholders in the adoption of environmental policy. The goal of this paper was to start to address that lacuna. Using pooled cross‐sectional time series analyses of environmental standards in 18 Western parliamentary democracies (1990–2012), our initial findings indicate women officeholders are associated with the adoption of higher environmental standards. 相似文献

The Narrative Policy Framework (NPF) focuses on the role of narratives, drawing from a rich scholarship in narrative, language, and culture. Despite the understanding that narratives are constructions of language and that narrative construction differs across languages, NPF studies have not focused on policy narratives in languages other than English. Language characteristics of narratives are important to assess the stability of policy narratives when there are multiple dominant languages in a political system. This study investigates the use of narrative elements in policy narratives in agricultural biotechnology policy in India across Hindi and English media coverage to examine the NPF assumption that narratives have generalizable narrative elements irrespective of variation in linguistic context and, specifically, tests the transportability of narrative elements. Findings validate the transportability of narrative elements in Hindi narratives, indicate variation in the use of narrative elements over time, and have implications for applying NPF across languages. 相似文献

Seismologists have reported that a majority of recent earthquakes in Oklahoma have been triggered by the activities of oil and gas companies. Despite this fact, there is evidence of strong opposition toward earthquake mitigation policy. In this article, we argue that how individuals define issues affect their policy choice. Furthermore, we incorporate the concept of venue shopping from the literature on macro theories of the policy process to investigate the effect of problem definition in shaping individual venue preference for policy choice. Using unique survey data, we find that problem definition, particularly issue causality and issue image, is strongly related to individual support for earthquake mitigation policy. However, a more nuanced relationship between individual problem definition and venue preference is observed. Our findings contribute to scholarly endeavors to understand the politics of problem definition at an individual level, which may be the precursor of understanding policy choices at the institutional level. 相似文献

Since its inception in 2009, Uber has grown into a technology behemoth, with operations in over 70 countries and 500 cities around the world. Along the way, it has successfully forced regulatory upheaval in hundreds of local taxi markets controlled by municipal authorities. In this sense, Uber is not only a market disruptor, but also a policy disruptor. This paper examines the nature of such policy disruption at the local level by reviewing regulatory responses to Uber in ten North American cities. We find that regulatory outcomes are a function of two factors: Uber’s government relations strategy, either cooperative or confrontational, and the degree to which local governments perceive Uber as complementary or harmful to the existing marketplace. We conclude by proposing a typology of regulatory responses to Uber as a basis to identify patterns in the behavior of municipal regulatory authorities and political leaders. 相似文献

Among the more recognizable programs related to natural and sustainable food is the United States Department of Agriculture’s National Organic Program. Although the robustness of the organic food market is difficult to contest, many debate the extent to which U.S. organic policy outcomes adequately serve consumers and the organic agriculture producers they rely on. This paper engages the debate from the perspective of certified organic producers. Drawing on the results of a nationwide survey of USDA‐certified producers, we first provide a snapshot of how producers assess the environmental, consumer, and market impacts of U.S. organic food policy. We then examine the extent to which organic producers’ policy impact perceptions are associated with their alignment with an “organic ethos”—understood as producers’ commitment to core organic principles and the organic movement. The paper highlights producers’ values as perceptual filters and cognitive mechanisms that help shape producers’ policy impacts perceptions, illustrating a contributing factor to the enduring nature of organic policy debates. 相似文献
