This study investigated which information sources Italian consumers use most frequently when they have a question about food safety in order to obtain useful insights to inform food risk communication. In 2011, a national survey was conducted targeting Italian people responsible for purchasing and preparing food for their households. Respondents’ choices of information sources on food safety were correlated with their socio-demographic and behavioural characteristics, their levels of objective knowledge, their levels of trust towards some authorities and their levels of self-perception regarding risk exposure. Our data analysis identified those information channels that are most likely to reach Italians actively seeking information. Mass media (radio/television/newspapers) were the most frequently used information source, followed by the Internet. Age, educational qualification, employment status, geographical area, family status and objective knowledge were the variables that influenced the choice for information sources used by the Italian population. The frequency of buying food products, the frequency of eating put and the frequency of cooking also showed a dependency relation. The profiles of those who actively seek information were also outlined. Among these, the Mass media users’ and the Internet users’ profiles were further analysed. Results show that Italian consumers do actively seek information about food safety, revealing that food safety continues to be a concern for the Italian consumers. Their interest in this topic represents an opportunity for public health authorities to address an audience of receptive consumers. Such information will be valuable in the design of targeted communication campaigns to increase consumers’ knowledge and awareness of food safety issues and will help authorities to choose the most effective channels through which to deliver key messages.  相似文献

Firms often procure the same input via multiple means, e.g., making and buying. Recent papers have yielded rich, but inconsistent, theoretical and empirical insights. Resolving these inconsistencies requires reconceptualizing two aspects of plural sourcing: what and how. We reconceptualize plural sourcing as a set of combined governance modes—make‐and‐buy, make‐and‐ally, and buy‐and‐ally—which differ in their capabilities and limitations. We demonstrate our reconceptualization's potential with propositions predicting the choice of specific plural sourcing modes. Copyright © 2013 John Wiley & Sons, Ltd.  相似文献

The study aims to assess Italian consumers’ attitudes towards food risks and seeks to outline their socio-demographic and behavioural characteristics on the basis of their attitudes (self-protective and non-self-protective) towards food risks. Using the Computer-assisted telephone interviewing survey method, a sample of 1000 Italian consumers was interviewed on risk perception issues and general eating habits. Factor analyses on the consumers’ propensities to read the label when buying a food product for the first time, their propensities to seek food-related information and their perceived levels of exposure to food risks have enabled us to define Italian consumers’ attitudes towards food risks. Distinguishing between consumers with more self-protective attitudes and those with less self-protective attitudes and identifying their distinctive socio-demographic and behavioural characteristics (e.g. gender, age, the frequency with which respondents do grocery shopping and the channels used for further inquiry) are crucial for communication campaigns aimed at reducing consumers’ exposure to food risks.  相似文献

In the last decade, the demand for sustainable and social investments has improved. The mutual funds industry has responded to market needs by offering a number of investment products focused on Environmental, Social and Governance (ESG) companies. The aim of this article is to understand if an ESG score can actually be considered a valid criterion that portfolio managers could adopt, along with traditional risk–return optimisation, in selecting asset portfolios. The paper analyses the link between the performance and the ESG score of different sectoral portfolios (one for each sector of the Global Industry Classification Standard), entirely composed of ESG assets, in the search for a clear and strong positive correlation that could suggest an overall advantage to focus on an ex ante choice of assets with high ESG scores.  相似文献

This study examines the relationship between various financial inclusion measures and banks' performance across multiple countries with varying institutional, regulatory and income levels. To construct an aggregate bank performance index, we employ principal component analysis, which utilises a set of critical indicators summarised by the CAMEL rating system, including banks' solvency, asset quality, efficiency, profitability and liquidity. Our primary findings indicate that different measures of financial inclusion exhibit varying associations with bank performance. Specifically, there is a trade-off between bank performance and credit deepening, especially in high-income nations. Conversely, in low-income nations, higher financial inclusion, measured by deposits to GDP, number of deposits, and number of borrowers, does not affect bank performance adversely. Banks in low-income nations could achieve significant gains by improving financial access and enhancing regulatory environments.  相似文献

While prior consumer studies have adopted various theoretical perspectives to explain individuals' reactions to disasters, scant attention has been paid to the role of ontological security in shaping those responses. This study attempts to fill this knowledge gap by qualitatively exploring ontological security in two contexts: man-made and natural disasters. To this end, we conducted 35 focus groups in the UK, Germany, and France to address how people reacted to terrorist attacks and the COVID-19 pandemic respectively. Through thematic analysis, three themes emerged: fear versus anxiety, oneself versus others, and materialistic versus experiential purchases. Man-made disasters appear to elicit fear, concern for self, and a preference for materialistic purchases, whereas natural disasters seem to trigger anxiety, concern for others, and a preference for experiential purchases. Both types of disasters seem to evoke a desire to escape from reality. In closing, we discuss both transitory and prolonged threats to ontological security and how they shape individuals' behaviours while restoring their security.  相似文献

We study optimal promotion decisions of hierarchical firms, with one junior and one senior managerial position, which interact in a search and matching labour market. Workers acquire experience over time while being employed in a junior position and the firm has to determine the experience level at which the worker receives a promotion which allows her to fill a senior position. Promoted workers move to the senior position in their current firm, if it is vacant, otherwise they search for senior positions on the market. The promotion cut-offs of the competing firms exhibit strategic complementarity, but we show that generically a unique stable symmetric general equilibrium exists. We find that stronger competition among firms leads to later (earlier) promotions if the initial number of firms is small (large) giving rise to an inverse U-shape relationship. In the presence of two skill groups, stronger competition among firms reduces the importance of skill differences, so the gap in wages and promotion times decreases with the number of firms. The model is compatible with empirical evidence that high-skill workers are promoted faster than the low-skilled and that internal promotions are more frequent than cross-firm moves to a higher hierarchical position.  相似文献

This study empirically investigates the effects of three destination consumptions (namely symbolic, experiential and functional) on tourists' destination attachment and satisfaction, and further on destination loyalty at a heritage tourism destinations. Using a sample of 512 international tourists visiting Angkor, Cambodia, results reveal that all three types of consumptions have significantly positive effects on destination attachment and satisfaction, which in turn positively affect destination loyalty. However, the effects of symbolic consumption and experiential consumption are greater than that of functional consumption. The results also support the importance of the role of destination attachment in the quality–satisfaction–loyalty relationship. Copyright © 2016 John Wiley & Sons, Ltd.  相似文献

In 2014, Russia responded to sanctions imposed by a coalition of Western countries with a retaliatory import embargo. I draw on this unique case study and a customs data set on firm-level import transactions to investigate the ramifications of Russia's counter-sanctions on firm-level foreign trade. Using detailed data and a triple-difference estimation strategy, I examine micro-level dynamics and heterogeneities that aggregate data alone do not reveal. I identify the effects of the embargo on the extensive margin (the probability that a firm imports a particular product from a given country in a particular time period) and the intensive margin (the value of a firm's import transaction) of firm-level trade, as well as its effects on logged unit values. The main findings of this study show that the embargo had statistically significant negative impacts on extensive and intensive margins of firm-level trade. I also pinpoint evidence of multiple exemptions from the embargo and a large degree of heterogeneity of firm-level responses to the embargo based on firm attributes, such as firm size and government connection.  相似文献
