Corporate sustainability reports are supposed to provide a complete and balanced picture of corporate sustainability performance. They are, however, usually voluntary and thus prone to interpretation and even greenwashing tendencies. To overcome this problem, the Global Reporting Initiative (GRI) provides standardized reporting guidelines challenging companies to report positive and negative aspects of an organization’s sustainability performance. However, the reporting of “negative aspects” in particular can endanger corporate legitimacy if perceived by the stakeholders as not being in line with societal norms and values. Starting from the theoretical lenses of economics-based disclosure theories and socio-political theories of disclosure, the focus of this study therefore was to analyze the communicative legitimation strategies companies use to report “negative aspects,” i.e., negative ecological and social impact caused by corporate activity. Using qualitative content analysis of GRI-oriented sustainability reports from companies listed on the US Dow Jones Industrial Average Index and on the German DAX Index, we identified six legitimation strategies. We discuss these strategies regarding to symbolic and substantial management of legitimacy. We show that symbolic legitimation strategies aiming at modifying the perception of legitimizing stakeholders dominate in the reports at hand. Such persuasion, however, does not meet the requirement of impartiality as postulated by the GRI guidelines. Building upon this conclusion we propose a concise characterization of “negative aspects” and develop a GRI-compliant schema of reporting about them. In doing so, we offer a way to improve the overall “balance” of sustainability reporting contributing to a true and fair view in sustainability disclosure.  相似文献

Personalization is a key component of an interactive marketing strategy. Its purpose is to adapt a standardized product or service to an individual customer's needs. The goal is to create profit for the producer and increased value for the consumer. This goal fits nicely into traditional notions of segmentation. Applications of personalization have advanced greatly in conjunction with the Internet, since it provides an environment that is information rich and well suited to interactivity. This article reviews past research on personalization and considers some examples of personalization in practice. We discuss what we believe are key problems and directions for personalization in the future.  相似文献

Advertising and design are only part of the total marketing/communications mix. Favourable reputations are not made simply with clever visual schemes or even from the provision of what the market wants. To communicate effectively with a genuine and individual voice, there has to be a clear understanding within organizations as to what they are and what they stand for. The strength and confidence derived by staff and management alike from being part of and contributing towards the development of distinctive organizations are vital ingredients in the generation and sustenance of effective corporate images.  相似文献

The aim of this study was to test an intervention aimed at addressing the risk of injury in infants 2 - 12 months of age. A non-blinded, randomized controlled trial was conducted, whereby parents were randomly assigned to either a control or one of two intervention groups. Parents completed questionnaires regarding safety behaviours and injuries at the 2 (baseline), 6 and 12 month immunization visit at the community health unit. During the 2 month visit to the health unit, the two intervention groups received a home safety kit containing nine items, an instructional brochure and a risk assessment checklist. Subjects randomized to the safety kit plus home visit group also received a standardized home visit from a community health nurse. Two of the 14 parental safety behaviours showed a significant increase in use among parents in the intervention groups. Neither of the interventions was associated with a reduction in parent-reported injuries among children. It was concluded that home visitation may provide a beneficial adjunct to the provision of safety devices and may increase use by parents.  相似文献

As part of an investigation into the performance of heating systems and the effectiveness of energy saving measures, temperatures have been monitored in forty centrally heated homes. The addition of extra insulation had no effect on the way people operated their heating system or on the temperature level set in the main living room. However, bedrooms were warmer and the importance of individual room temperature controls demonstrated. Differences between people's thermal requirements in domestic and office environments are considered.  相似文献

This study examines whether the financial markets penalize public corporations for unethical business practices. Using event study methodology, it is found that upon the announcement that a firm is under investigation or has in some way engaged in unethical behavior, a statistically significant negative abnormal (excess) return is found. This suggests that firms are indeed penalized for their unethical actions.  相似文献
