A form of strategic mediatization, media catching is the reversal of the traditional public relations process of pitching story ideas to journalists using press releases, feature pitch letters, and other techniques. In media catching, journalists working on specific stories reach out to large numbers of public relations practitioners using a variety of technologically aided services with queries for specific information. Using quantitative and qualitative content analyses, this study examines journalist queries submitted through a media request service, Pressfeed.ru, to understand the dynamics of the media-catching trend in Russia. Findings show a substantial gap between reporters’ expectations and public relations professionals’ goals and abilities, and a fragmentation of media outlets’ practices. The findings also revealed similarities in the growth and usage patterns of the Russian service to the first American media-catching service, Help-a-Reporter-Out. An empirical investigation is warranted to test an emergent model of the mutual influences of reporters, public relations specialists, internal (organizational values) and external (societal culture, political climate) factors during the process of media catching across different cultures and countries. 相似文献

This study explores tourists' attitude towards healthy eating and its influence on their travel eating behaviour. Based on focus group interviews and literature review, two instruments were developed to measure healthy eating attitude and travel eating behaviour. Factor analysis results revealed two healthy eating attitude factors (‘food content and nutrients’ and ‘balanced diet and eating habit’), and five travel eating behaviour factors (‘novelty’, ‘risk avoidance’, ‘health steadfastness’, ‘familiarity’, and ‘food supplement and medicine’). The relationships among the factors were examined using structural equation modelling. The findings revealed that respondents who had a stronger attitude towards ‘balanced diet and eating habit’ tended to be more motivated by the ‘novelty’ factor; whereas ‘risk avoidance’, ‘health steadfastness’ and ‘familiarity’ were found to be associated with a stronger attitude towards ‘food content and nutrient’. The findings suggest that the healthy eating attitude construct is multidimensional and healthy eating conscious tourists should not be treated as a homogeneous group. 相似文献

The study was designed to clarify the ambivalent relationships between work–family conflict (WFC) and measures of satisfaction. Both the direct and indirect effects of WFC on job and life satisfaction were investigated. Job satisfaction was also separated into two components: affective reaction and cognitive appraisal. Data were collected by a field survey of 121 sales managers from 26 hotels in China. Structural Equation Modeling (SEM) indicated a critical role of one's affective reaction to his/her job in the relationship between WFC and life satisfaction. Specifically, the present study found that both work interfering with family (WIF) and family interfering with work (FIW) have significant negative association with an individual's affective reaction to his/her job, while only FIW reduced the cognitive appraisal of a job. Further, affective reaction, rather than cognitive appraisal, had a significant positive correlation with life satisfaction. Finally, FIW was negatively associated with life satisfaction. The results suggest the strategic role of family friendly human resource polices in hotels. 相似文献

Distance functions are increasingly being augmented, with environmental goods treated as conventional outputs. A common approach to evaluate the opportunity cost of providing an environmental good is the exploitation of the distance function's dual relationship to the value function. This implies that the opportunity cost is assumed to be non‐negative. This approach also requires a convex technology set. Focusing on crop diversification for a balanced sample of 44 cereal farms in the East of England for the years 2007–2013, this paper develops a novel opportunity cost measure that does not depend on these strong assumptions. We find that the opportunity cost of crop diversification is negative for most farms. 相似文献

Cost-Effective Targeting of Land Retirement to Improve Water Quality with Endogenous Sediment Deposition Coefficients 总被引:1,自引:0,他引:1

An integrated framework that combines spatial and biophysical attributes of land with a hydrological model and an economic model is developed to identify cropland for enrollment in the Conservation Reserve Enhancement Program. Sediment deposition coefficients are determined endogenously depending on the land-use decisions on other land parcels. Application of this framework to a watershed in Illinois demonstrates that highly sloping land adjacent to water bodies should be selected for retirement. A marginal value rental payment scheme can achieve program goals of 20% sediment abatement at 39% lower cost than a productivity-based rental scheme. 相似文献
