The aim of this article is to investigate to what extent small‐firm foreign patents differ from those of their larger counterparts. The research setting consists of the population of U.S.‐owned small and large businesses with patent applications at the World International Patent Organization during 1996–2006 in the emerging field of nanotechnology. Findings reveal a significant and growing contribution of small firms to the globalization of patents. The analysis also suggests that small‐firm patents tend to be more novel and embedded in domestic innovation networks than large‐firm patents. Policy implications are multiple, including putting international patenting on the policy agenda and helping highly innovative small companies to explore foreign commercial opportunities in new markets of capital and technology.  相似文献

The role of the public administration is crucial for the development of smart cities. Several scholars have highlighted the need for greater contributions focused on the relationship between public administration and smart cities. This work aims to map the contributions on the topic highlighting the status of the field in the recent years. A bibliometric analysis was performed on a sample of articles published in business and management journals. The analysis was carried out using the R-studio Bibliometrics package. Results show that research on the topic is still in an initial stage and has several gaps that future studies could fill. The study is useful for scholars because it identifies the topics analyzed by previous research and highlights future research questions that could be investigated. The analysis highlighted the areas studied by scholars on the topic: urban planning, sustainable development, governance approach, Internet of Things and information and communication technologies.  相似文献

In the recent past, European states have adopted mandatory due diligence (MDD) laws for holding companies accountable for the environmental and human rights impacts of their supply chains. The institutionalization of the international due diligence norm into domestic legislation has, however, been highly contested. Our contribution analyzes the discursive struggles about the meaning of due diligence that have accompanied the institutionalization of MDD in Germany and France. Based on document analysis and legal analysis of laws and law proposals, we identify a state-centric, a market-based, and a polycentric-governance discourse. These discourses are based on fundamentally different understandings of how the United Nations Guiding Principles on Business and Human Rights should be translated into hard law. By outlining these discourses and comparing the related policy preferences, we contribute with a better understanding of different ways in which MDD is institutionalized, with important consequences for the possibilities to enhance corporate accountability in global supply chains.  相似文献

When established in 1951, the West German Foreign Office resembled its pre-1945 Berlin Ministry predecessor in many ways. Notably, about 45 percent of Bonn’s diplomats came from the old service. Such continuities raised concerns about a restoration of old diplomatic traditions and attitudes. However, significant changes in German diplomacy—its West German variant—soon became evident, not least in terms of diplomatic style and methods. This analysis explores how the Foreign Office’s staff adopted, promoted, or rejected such changes. It assesses institutional processes of transformation and examines why diplomats were willing to “re-learn” diplomacy after the Second World War. Likewise evaluated are the problems and limits of re-orientation. By focussing on (dis)continuities within the Foreign Service in the 1950s and 1960s, the analysis contributes to the general field of research on processes of transition in West Germany after the end of the Third Reich.  相似文献

The current article seeks to add to the quantitative approach to understanding terrorism by examining the logic underlying terrorist choice of targets and timing within the context of the Chechen–Russian conflict. Using data on Chechen rebel bombings in Chechnya and Russia from 1997–2003, the analysis revealed support for a logic underlying terrorist choice of targets. The results indicated that civilian targets were more likely to be targeted in Russia than in Chechnya, illustrating the importance of examining contextual effects within quantitative approaches to terrorism. The results also implicated an affect of weather and urbanization. Implications of the results and future directions for research are discussed.  相似文献

Considers the issue of patent rights in Argentina, Brazil, Chile, and Mexico. Reviews both theoretical and empirical literature on fitting patent systems to national circumstances. Data are considered shedding light on trade flows and capital formation, two areas impacted by strong or weak protection. Recommends a general hybrid system for Latin American nations, meeting GATT standards while remaining adaptable to individual country needs.  相似文献

The research in representative bureaucracy that examines the extent to which racial congruence impacts bureaucrats’ decisions is mixed. This study adds to this literature by examining the impact of representative bureaucracy on the level of force that police officers use and whether they make an arrest in use of force encounters, while taking into consideration key situational conditions. Using individual-level data from New Orleans to estimate this impact, the authors find that racial congruence and incongruence impact policing outcomes even in the presence of situational shortcuts that cue decision-making. The findings show that the benefits of representation are conditional on the outcome. Black officers are less likely to use higher levels of force on Black civilians. Yet both Black and White officers are less likely to arrest White civilians in use of force encounters. This suggests that interactions in which bureaucrats have less discretion (e.g., arrests) may offer limited opportunities for active representation.  相似文献

Forensic casework from past‐conflicts relies on the corrected historical Trotter data for stature estimation in Fordisc. For roughly 10 years’, stature estimation using this data has produced point estimates for the tibia that are on average 1.25 inches less than the other long bones. This issue was identified after applying the equations derived from Fordisc to the USS Oklahoma commingled assemblage. Reevaluation of Fordisc revealed that a correction factor of 20 mm, instead of 10 mm, was mistakenly applied to the Trotter tibia data. Historical forensic anthropology reports written at the Defense POW/MIA Accounting Agency were utilized to identify that the overcorrection is isolated to Fordisc 3 with an error rate of 5% of known antemortem statures falling outside of the prediction intervals that relied on the tibia. Further evaluation of the Oklahoma sample indicates the 10 mm correction is still producing point estimates less than the other long bones.  相似文献
