Companies commonly issue sustainability or corporate social responsibility (CSR) reports. This study seeks to understand worldviews of corporate sustainability, or the corporate message conveyed regarding what sustainability or CSR is and how to enact it. Content analysis of corporate sustainability reports is used to position each company report within stages of corporate sustainability. Results reveal that there are multiple coexisting worldviews of corporate sustainability, but the most dominant worldview is focused on the business case for sustainability, a position anchored in the weak sustainability paradigm. We contend that the business case and weak sustainability advanced in corporate sustainability reports and by the Global Reporting Initiative are poor representations of sustainability. Ecological embeddedness, or a locally responsive strategy that is sensitive to local ecosystems, may hold the key to improved ecological sensemaking, which in turn could lead to more mature levels of corporate sustainability worldviews that support strong sustainability and are rooted in environmental science. This must be supported by government regulation. Copyright © 2017 John Wiley & Sons, Ltd and ERP Environment  相似文献

The creation of the Asian Infrastructure Investment Bank (AIIB)was welcomed by the World Bank but opposed by the Obamaadministration. The paper explains China’s positive relationshipwith the Bank and the Organization for Economic Cooperation andDevelopment (OECD) in terms of the mission of the Bank, sharedby the OECD, to develop and deepen the global economy. The AIIBand the related Belt and Road initiative promise to do this throughinvestment in infrastructure and connectivity in and around thepoorly integrated Eurasian landmass. But while the current Chineseleadership has supported an inclusive global economy based uponfree trade and supported by multilateral institutions, China’s controlof resources outside the multilateral framework and adherence topractices that challenge liberal principles prompt suspicions thatthese commitments are either disingenuous or anyway subjectto reversal. In itself, therefore, the AIIB provides no conclusiveevidence either way on China’s future course.  相似文献

Recent methodological developments provide a way to incorporate the temporal dimension when accounting for spatial effects in hedonic pricing. Weight matrices should decompose the spatial effects into two distinct components: bidirectional contemporaneous spatial connections; and unidirectional spatio-temporal effects from past transactions. Our iterative estimation approach explicitly analyses the role of time in price determination. The results show that both spatio-temporal components should be included in model specification; past transaction information stops contributing to price determination after eight months; and limited temporal friction is exhibited within this period. These findings highlight the decidedly non-linear temporal patterns of such information effects.  相似文献

This study investigates the correlates of a resident's walking behaviors and aims to shed light on mechanisms through which walking may be encouraged. The results of this investigation paint a complex and nuanced picture of the residents’ walking behaviors in South East Queensland, Australia. The results suggest that sociodemographic characteristics separately may contribute greatly to whether or not one engages in walking behaviors. Further, cumulatively these differences might be greater for some groups of residents compared to others. One of the most prominent findings of the study is that the purpose, the characteristics of the origin, and the characteristics of the destination of a trip tended to be similar in the heterogeneity they exhibit over the distribution of time spent walking. For example, pick something up, undertake work, or engage in personal business, move to or from a workplace, shop, or social place are activities that tend to be associated with walking as a main mode of transport and a higher number of walking episodes. However, these trips tended to be short.  相似文献

This study examines financial reporting quality (FRQ) effects around voluntary International Financial Reporting Standards (IFRS) adoptions by German private firms across two important dimensions, earnings quality and disclosure practices. To capture differences in the motivations for IFRS adoptions, we identify four different types of IFRS adopting firms based on a comprehensive set of firm characteristics. We observe earnings quality improvements around IFRS adoptions primarily for one type of firm, which is young, fast growing and seeking access to public equity markets. Using a matched sample of private German GAAP and IFRS reporting firms, we find some evidence suggesting that IFRS also contribute to higher earnings quality. Recognizing that our earnings quality metrics are only incomplete measures of FRQ, we also compare the disclosure practices of IFRS and German GAAP firms. We find that all IFRS firm types disclose significantly more information in their financial reports and show a higher propensity to publish their financial reports voluntarily on the corporate website. Our findings indicate that failure to identify earnings quality changes around IFRS adoption cannot be automatically interpreted as IFRS adoption having no effect on the FRQ of (private) firms. Collectively, our results suggest that both incentives and accounting standards shape private firms’ FRQ.  相似文献

The Basel Capital Accord (pillar 3) states that disclosure of information (transparency) is essential to financial stability. This study analyzes, through inflation reports, the disclosure of information from the Central Bank of Brazil concerning the credit market. We consider credit risk and capital buffers as measures of financial stability in this analysis. Furthermore, in order to measure the perception of the monetary authority on the credit market, we built two indices based on the central bank’s communication on credit development. We performed a panel data analysis based on a sample of 125 banks for the period from June 1999 to September 2014 (7000 observations). The findings suggest that central bank communication regarding expectations concerning the credit market contributes to financial stability. Therefore, this kind of communication of central banks (about credit development) may constitute an important macroprudential tool to improve financial stability.  相似文献

ABSTRACT

This study discusses how to apply counseling-learning (CL) principles to a particular e-learning solution for teaching a tourism-related subject via a massive open online course (MOOC). Several effective caring patterns in achieving learning-related goals and being part of a community according to the CL principles are presented and discussed using the MOOC “eTourism: Communication Perspectives” as a case study. The study underlines how the MOOC platform can act as a place for contents enjoinment and active learning. Moreover, the active role of social media for increasing the engagement of learners in the proposed activities and for developing a sense of the community is identified. In particular, Facebook and Twitter can act as places for community building and informal social interactions among learners that last beyond the completion of the course, which in turn can be a valid aid for continuing the relationships among instructors/learners and learners/learners, and for reaching new ones.  相似文献

ABSTRACT

Alumni communication is vital in sustaining the relationship between alumni and their alma maters. This research investigated four cohorts of alumni, and their intentions to use a range of traditional and digital communication channels, including social media. An online questionnaire was sent to 8060 alumni and resulted in 595 usable responses, yielding a 7% response rate. The research results showed that alumni have the highest intentions to use the alumni e-newsletter and the alumni Website and the lowest intentions to use social media, e.g., Twitter, Instagram, and YouTube. Among alumni cohorts, significant statistical differences in their intentions to use these communication channels were identified. Given our findings, alumni communication staff are encouraged to leverage different communication channels targeting alumni in different age groups.  相似文献

This article highlights the inadequacy of classical and neoclassical theories for understanding the set of changes experienced by economic systems in their process of development. The institutional dimension concerning the issue of well-defined rules (through the introduction of economic policies) and involving all stakeholders in the regulatory process (starting from the firm), seems to better interpret micro- and macro-economic aspects of the evolving capitalist model. This means questioning the complicated economic governance and society in the transition from the nation-state to a world society (or world state).  相似文献
