Cities are key drivers of global climate change, with the majority of greenhouse gas (GHG) emissions being tied to urban life. Local actions to mitigate and adapt to climate change are essential for stabilization of the global climate and can also help to address other urban ecological problems such as pollution, decreasing biodiversity, etc. Companies are important urban actors in the development of low‐carbon cities because they provide a multitude of goods and services to city populations and directly influence urban carbon dioxide (CO2) emissions. This is a new area of research. While studies on corporate sustainability are numerous, there is little, if any, existing research that examines the role of companies in climate change adaptation and mitigation within specific urban areas. Urban ecologists also have not examined how corporate activity affects urban systems. Taking a multi‐disciplinary systems approach, we present a conceptual model of the role of companies in managing urban interactions with the climate system. We also present empirical findings illustrating how one company ‘partners’ with the city of Rotterdam to test electric vehicles as a pilot project for urban climate adaptation and mitigation.

We describe an ambiguity hedging problem in Ellsberg experiments, where combinations of individually ambiguous bets eliminate aggregate ambiguity, and which may yield incorrect classifications of ambiguity averse subjects. We propose a new classification consistent with this hedging possibility.  相似文献

This article examines unconventional entrepreneurship (accidental or end‐user entrepreneurs) to determine whether the decision‐making phase of the entrepreneurial process is collective. The analysis identified a virtuous circle that links knowledge, innovation, judgment, and decision making to collective interactions built on passion, experience, and sharing. To study food bloggers as unconventional user entrepreneurs, data were collected and analyzed using netnographic analysis. A supplementary online survey of food bloggers and their followers was also performed. Three groups of food bloggers are identified: amusing, functional, and fervent. Only fervent food bloggers, thanks to the virtuous circle built on passion, experience, and sharing as enablers, can be considered accidental or end‐user entrepreneurs.  相似文献

This study extends the leisure constraint model by examining the role that popular nationalism has in Chinese outbound travel. Using a case study approach based on the 2012 Diaoyu/Senkaku Island Incident between China and Japan, the study demonstrates how Chinese popular nationalism has the potential to shape the geopolitical environment of all outbound Chinese tourism. The study proposes a new model that can be used to illustrate how popular nationalism may affect bilateral tourism in other settings. Findings of this study offer important insights for both scholars and practitioners contributing to the understanding of the impact of Chinese popular nationalism on bilateral tourism flows.  相似文献

This study examines the impact of creditor rights and country governance on cash holdings using a sample of firms from 47 countries. We hypothesize that cash holdings are smaller when both creditor rights and country governance are high. In these circumstances firms will not need to hold as much cash for future investments needs (precautionary funds) because firms will expect that funds will be available in the future. Our findings support our hypothesis and hold for alternative definitions for cash holdings, different country samples, different definitions of governance and concerns about endogeneity.  相似文献

Abstract

Motivating consumers to conserve energy has proven to be a difficult task in the United States. One tactic that has been used on a limited basis by the Department of Energy is paid advertising. This paper examines the role of conservation within the country's broader energy problems, delineates several consumer issues that affect the success of government conservation programs, discusses the controversy surrounding the use of paid advertising to promote consumer conservation efforts, and describes those DOE programs that have used paid advertising as an integral component of conservation program strategy.  相似文献

In this article, the authors describe the place of econometrics in undergraduate economics curricula in all American colleges and universities that offer economics majors as listed in the U.S. News & World Report “Best Colleges 2010” guide (U.S. News & World Report 2009). Data come from online catalogs, departmental Web sites, and online course syllabi. About one-third of the schools require econometrics of all students majoring in economics, about half require it of none, and a sixth require it of some, but not all, economics majors. Among universities with economics PhD programs and liberal arts colleges, almost all those ranked in the top 10 require it. Below the top 10, there is little correlation between ranking and econometrics requirements. Liberal arts econometrics classes are much more likely to require research projects than their counterparts in universities.  相似文献

Plagiarism strikes at the heart of academe, eroding the fundamental value of academic research. Recent evidence suggests that acts of plagiarism and awareness of these acts are on the rise in academia. To address this issue, a vein of research has emerged in recent years exploring plagiarism as an area of academic inquiry. In this new academic subject, case studies and analysis have been one of the most influential methodologies employed. Case studies provide a venue where acts of plagiarism can be discussed and analyzed in a constructive manner, and that is the primary purpose of this article. Unlike previous studies, however, we focus on the role of the publisher, a key player in dealing with acts of plagiarism, but one who has received little attention in the academic literature. Specifically, we examine how an academic publisher addressed allegations of plagiarism and how the publisher’s decision-making affected the outcome. We analyze the case by applying the guidelines from different frameworks and ethical theory and develop recommendations from the lessons evidenced, the second main objective of our article. This analysis advances the dialog on academic plagiarism by exploring the role of the publisher from a deontological perspective of ethical absolutism.  相似文献
