The best presentation of a nation's cultural heritage has been a recurrent theme in the scientific and cultural debate. Few studies, however, have investigated how cultural organizations are influenced by digitization when communicating corporate social responsibility. By adopting a multiple case study approach, we investigated a sample of virtual museums and their digital CSR culture. This study contributes to the literature on CSR effectiveness in cultural organizations, by focusing on how digitization is influencing the attitude toward CSR disclosure, in order to provide suggestions for cultural managers, scholars, policymakers and practitioners alike. More specifically, this paper aims to examine stakeholders' perceptions in digital cultural organizations as a new form of social responsibility. To the best of our knowledge, this is the only study that applies this perspective to the analysis of the digitization process through CSR, currently under way across cultural institutions around the world.  相似文献

Past research shows how information about corporate irresponsibility that contradicts an organization's social responsibility commitments causes hypocrisy perceptions. Extant research on stakeholder engagement however, has not explained how inconsistent corporate social responsibility (CSR) information affects the perceptions of consumers strongly connected with a brand. This study investigates how, rather than protecting the firm against hypocrisy perceptions, self-brand connectedness magnifies the negative effect of inconsistent CSR information. We tested the research hypotheses across two experimental studies, using both fictitious and real brands in two different industries. We estimated a multi-group structural equation model model to show how self-brand connectedness increases people's willingness to distance themselves from the hypocritical brand. Results show that consumers that feel close to the hypocritical brand have a stronger desire to disengage their identity from the brand and protect their self-esteem. The desire to avoid the brand in turn drives more negative consumer reactions in terms of brand attitudes, brand loyalty and negative word of mouth. Our findings contribute to the literature by demonstrating that a close relationship between the consumer and the brand may aggravate behavioral reactions to hypocrisy perceptions. This is the first study to consider how hypocrisy perceptions influence attitude and behaviors of consumers that are closely connected to the company. Our results extend research on hypocrisy perceptions and brand avoidance by showing that closely connected consumers are especially likely to reject brands that send inconsistent messages about their involvement in CSR.  相似文献

Predator holes in empty shells of Joania cordata and Argyrotheca cuneata (Brachiopoda: Megathyrididae) collected in the marine protected area “Secche di Tor Paterno”, central Tyrrhenian Sea, Italy (41°35′N–12°20′E, at depths of 20–28?m), were analyzed. Predation intensity was low but appreciable, with the more common species J. cordata preyed on more frequently (6.7?%) than A. cuneata (3.8?%). Three main types of holes were recognized: (1) cylindrical drill holes with a circular outline, (2) larger irregular holes with a jagged outline, and (3) small holes at the bottom of depressions in the shell. They were probably produced by muricid gastropods, crabs, and Foraminifera, respectively. The large, irregular holes were the most common type in both brachiopod species. Evidence for predator selectivity with respect to which valve, the position of the hole on the valve, and the size of the brachiopod with respect to those available was assessed. The ventral valve, the postero-medial portions of both valves, and larger (J. cordata) or medium-sized (A. cuneata) shells were more frequently holed.  相似文献

New finds of bones of the Egyptian Mongoose (Herpestes ichneumon), one from Portugal and one from Spain, were directly 14C dated to the first century AD. While the Portuguese specimen was found without connection to the Chalcolithic occupation of the Pedra Furada cave where it was recovered, the Spanish find, collected in the city of Mérida, comes from a ritual pit that also contained three human and 40 dog burials. The finds reported here show that the Egyptian mongoose, contrary to the traditional and predominant view, did not first arrive in the Iberian Peninsula during the Muslim occupation of Iberia. Instead, our findings are consistent with the hypothesis that the species was first introduced by the Romans, or at least sometime during the Roman occupation of Hispania. Therefore, radiocarbon dating of new archaeological finds of bones of the Egyptian Mongoose (Herpestes ichneumon) in the Iberian Peninsula push back the confirmed presence of the species in the region by approximately eight centuries, as the previously oldest dated record is from the ninth century. With these new dates, there are now a total of four 14C dated specimens of Egyptian mongooses from the Iberian Peninsula, and all of these dates fall within the last 2000 years. This offers support for the hypothesis that the presence of the species in Iberia is due to historical introductions and is at odds with a scenario of natural sweepstake dispersal across the Straits of Gibraltar in the Late Pleistocene (126,000–11,700 years ago), recently proposed based on genetic data.

A total of 65 operators involved in lichen mapping studies in central and northwestern Italy underwent quality control tests during five lichen biomonitoring workshops organized between 1999and 2000. The results showed that 75% quantitative accuracy and90% quantitative precision can be regarded as satisfactory levels for lichen biodiversity data; 65% proved to be sufficientfor accuracy of taxonomic identification in the field. Average correct assignment of the interpretative naturality/alteration class was only 48.7%. The results indicated the need for taxonomic training.  相似文献
