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

The 21st century public organization is faced with complex problems, informed stakeholders, and information flows, which necessitate a corresponding open system view of leadership. The traditional notions of public administration and new public management had been structured by strict bureaucratic rules and managerial flexibility, respectively. This paper begins by theorizing two hypothetical constructs (helicopter and deadbeat leadership), which engage in extreme micromanagement/surveillance and negligence/indifference, respectively. Those form basis for designing an optimal (transdisciplinary) leadership, which forges synergistic link between leaders, subordinates, and external actors in codesigning objectives and strategies to address societal problems. Strategies to promote transdisciplinary leadership are discussed.  相似文献

Slovenia has a rich tradition of associations and interest group activity dating back to the 19th century. To some extent, the development of the group system was stymied by the 60 years of authoritarian rule from the early 1930s to the late 1980s. However, the resilience of this tradition is evident in major developments in group activity since the return to democracy. In addition to influences from the past, including a neocorporatist tradition, is the impact of Slovenia's process of integration into the European Union. This article considers the extent to which the modern nature of the interest group system is both constrained by hangovers from the past but enhances by European integration, both of which have affected the development of Slovenia's majoritarian democracy.  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

This final article is a synthesis of findings from the seven country studies in this special issue. Although there are characteristics common to all group systems, particularly those transitioning to democracy, there are also significant differences. Analysis of these differences reveals a direct relationship between both the level of socioeconomic and political development and the characteristics of the group systems in all Balkan countries. In addition, we provide new insights into group system development and operation. These are particularly related to the impact of war, inter‐ethnic cleavages, constitutional arrangements (majoritarian and consociational), economic crises, geopolitics, and the major presence of external interests.  相似文献
