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

Addressing climate change requires consideration of mitigation and adaptation opportunities at multiple spatial scales. This is particularly true in the built environment, defined here to include individual buildings, neighborhoods, and the spaces between. The current U.S. political environment portends fewer resources and coordinating services for mitigation and adaptation at the federal level, however, reinforcing the relevance and necessity of actions at subnational levels. In this study, we evaluate the applicability of a polycentric model of governance to the implementation of mitigation and adaptation practices, as well as the presence of polycentric systems in the built environment. We assemble a database of practices with the potential to achieve both mitigation and adaptation objectives, as well as those that may be cross‐purposed or that may achieve one but not the other. We review practices to gauge the applicability of a polycentric model of governance to mitigation and adaptation practices in the built environment, and examine the attributes of three existing adaptation and/or mitigation programs to assess the extent to which they exhibit polycentric attributes. We conclude with recommendations for a broader research agenda, including efforts to develop more in‐depth examinations into individual programs and comparative analysis of performances of different governance attributes.  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

ABSTRACT

This is the introductory paper for a special issue which focuses on an exploration of how vertical inter-governmental political and fiscal bargains and horizontal variation in political, social and economic conditions across regions contribute to or undermine the provision of inclusive and sustainable social policies at the subnational level in Latin America and India. The papers incorporate both federal, as well as decentralized unitary states, pointing to common political tensions across unitary and federal settings despite the typically greater institutionalization of regional autonomy in federal countries. Jointly, the papers examine the territorial dimension of universalism and explore, in greater and empirical detail, the causal links between fiscal transfers, social policies and outcomes, highlighting the political dynamics that shape fiscal decentralization reforms and the welfare state. This introductory essay reviews existing scholarship, and highlights the contribution of the special issue to understanding these issues beyond OECD contexts.  相似文献

The two most recent Department of Homeland Security interior immigration enforcement programs, Secure Communities and the Priority Enforcement Program, have directed deportation efforts toward noncitizens convicted of crimes. One of their targets, the ‘criminal alien,’ has been (re)fashioned in political and legal discourses since the 1980s. Through critical discourse analysis of the 2013 immigration reform debates and their incorporation of the Violence Against Women Act (2013), this article examines the ways in which contemporary immigration policy renders the racialized ‘criminal alien’ (sexually) threatening to the ‘vulnerable’ woman. Dichotomous constructions of deserving and undeserving immigrants, in turn, bolster an array of strategies to manage the ‘risk’ of noncitizens, including border control and financial self-regulation.  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

While policymakers often make bold claims as to the positive impact of intellectual property (IP) rights on both developed and developing country economies, the empirical literature is more ambiguous. IP rights have both incentive and inhibitory effects that are difficult to isolate in the abstract and are dependent on economic context. To unravel these contradictory effects, this article introduces an index that evaluates the strength of IP protection in 124 developing countries for the years 1995 to 2011. We illustrate the value of this index to economics study and show evidence that is consistent with IP leading to increased growth. Our results are further consistent with two causal pathways highlighted in the literature: that IP leads to greater levels of technology transfer and increased domestic inventive activity. Yet other aspects of our study fit uneasily with this simple story. For example, we find evidence suggesting that increased levels of growth lead to greater levels of IP protection, contradictory evidence in the literature linking IP with growth, a lack of evidence that increased levels of IP protection lead to actual use of the IP system, and problems with what IP indexes measure. Because of this, we suggest another – and so far undertheorized – explanation of the links between IP and growth: that IP may have few direct effects on growth and that any causality is a result of belief rather than actual deployment of IP.  相似文献

A growing body of scholarship analyzes the emergence and resilience of forced labor in developing countries within global value chains. However, little is known about how forced labor arises within domestic supply chains concentrated within national borders, producing products for domestic consumption. We conduct one of the first studies of forced labor in domestic supply chains, through a cross‐industry comparison of the regulatory gaps surrounding forced labor in the United Kingdom. We find that understanding the dynamics of forced labor in domestic supply chains requires us to conceptually modify the global value chain framework to understand similarities and differences across these contexts. We conclude that addressing the governance gaps that surround forced labor will require scholars and policymakers to carefully refine their thinking about how we might design operative governance that effectively engages with local variation.  相似文献

Over the past decade, directional drilling and hydraulic fracturing enabled an unconventional oil and gas extraction (UOGE) boom in many regions of the United States, including parts of Pennsylvania. This revolution has created serious concerns about the capability of existing institutions to govern important societal outcomes associated with UOGE. We present a conceptual framework for assessing key societal outcomes influenced by UOGE governance. In applying this framework to Pennsylvania, we discern certain institutional strengths that have allowed the Commonwealth to reap appreciable short‐term economic growth from rich resource endowments. We also find, however, that several institutional weaknesses have allowed costs externalized to the environment, public health, and community integrity to offset some proportion of those economic benefits. Likewise, we find that governance of UOGE in Pennsylvania has contributed to a bifurcated sociopolitical landscape wherein adversarial coalitions dispute the legitimacy of the industry and its governance.  相似文献

Recent contributions in the domains of governance and regulation elucidate the importance of rule‐intermediation (RI), the role that organizations adopt to bridge actors with regulatory or “rulemaking” roles and those with target or “rule‐taking” roles. Intermediation not only enables the diffusion and translation of regulatory norms, but also allows for the representation of different actors in policymaking arenas. While prior studies have explored the roles that such RIs adopt to facilitate their intermediation functions, we have yet to consider how field‐level structuring processes influence (and are influenced by) the various and changing roles adopted by RI. In this study we focus on the mutually constitutive relations between field‐level change processes and the evolving roles of RIs by studying the rise of the International Council for Local Environmental Initiatives (ICLEI)/Local Governments for Sustainability, an RI serving as a bridge for sustainable urban development policies between the United Nations and local authorities. Using ICLEI as an illustrative case, we theorize four different processes of regulatory field structuration: problematization, role specialization, marketization, and orchestrated decentralization. We discuss their implications for RI roles in the field and further theorize the changing dynamics of trickle‐up intermediation processes as an RI gains power and influence.  相似文献
