This paper reports results derived from a survey of 2229 residents of, and 2151 visitors to the island of Waiheke, New Zealand. The study finds there was a close similarity of place image held by both visitors and residents. The paper examines the proposal that where congruency exists between visitor and resident image of place, there may be less negative perceptions of visitor impact on the part of residents. Both qualitative and quantitative data were collected and analysed, the former involving the use of CatPac?, a neural network program for analysing textual data. Little support was found for the contention that place images shared by residents and tourists would increase tolerance of tourists on the part of residents.  相似文献

This study investigated young female consumers' beauty product shopping behavioural patterns, their perceived importance of product attributes, and their attitude towards and purchase of natural beauty products. This study also examines whether consumers' product attitudes and shopping behaviours are influenced by their health and environmental consciousness. Data were collected from a convenience sample of 210 female college students enrolled at a south‐eastern university in the US. In order to examine the impacts of both health and environmental consciousness on other selected variables, the respondents were divided into four groups based on their scores on the two variables, and a series of analysis of variance were conducted to compare characteristics of the four groups. The results showed that health and environmental consciousness significantly influenced the importance placed on beauty product attributes. Additionally, those with a high level of both health and environmental consciousness were significantly more positive in their evaluations than those with low scores on both variables in their perceptions of natural beauty products. Those with low scores on both variables were significantly less willing than the other groups to pay more for natural beauty products. Analysis of variance results also indicated that the two groups with a high level of environmental consciousness purchased natural beauty products more frequently than those with a low level of health and environmental consciousness, indicating a relatively stronger impact of environmental consciousness than health consciousness on frequency of natural beauty product purchases. Health and environmental consciousness were both significantly related to a respondent's perceived level of knowledge of beauty products and ability to distinguish natural from conventional beauty products.  相似文献

Smooth and Sticky Adjustment: A Comparative Analysis of the US and UK   总被引:4,自引:0,他引:4  
This paper adopts the methodology of the microeconometric labor literature to analyze a common assertion from trade economists that reallocation within sectors is less costly than between sectors. Findings are compared across two countries (the UK and US) which have experienced very different recent aggregate unemployment experiences. Workers previously employed in "declining" sectors are more mobile than those employed in 'expanding' sectors in both countries, and individuals are more likely to switch sector the longer they are unemployed. A plausible explanation for this is that individuals initially attempt to find jobs that complement their general and specific skills in order to accrue the associated rewards, and move sector only as this prospect diminishes. This would seem to accord with the 'smooth adjustment hypothesis' which proposes that intraindustry adjustments are less costly than interindustry ones.  相似文献

Aims: This study investigated annual medical costs using real-world data focusing on acute heart failure.

Methods: The data were retrospectively collected from six tertiary hospitals in South Korea. Overall, 330 patients who were hospitalized for acute heart failure between January 2011 and July 2012 were selected. Data were collected on their follow-up medical visits for 1 year, including medical costs incurred toward treatment. Those who died within the observational period or who had no records of follow-up visits were excluded. Annual per patient medical costs were estimated according to the type of medical services, and factors contributing to the costs using Gamma Generalized Linear Models (GLM) with log link were analyzed.

Results: On average, total annual medical costs for each patient were USD 6,199 (±9,675), with hospitalization accounting for 95% of the total expenses. Hospitalization cost USD 5,904 (±9,666) per patient. Those who are re-admitted have 88.5% higher medical expenditure than those who have not been re-admitted in 1 year, and patients using intensive care units have 19.6% higher expenditure than those who do not. When the number of hospital days increased by 1?day, medical expenses increased by 6.7%.

Limitations: Outpatient drug costs were not included. There is a possibility that medical expenses for AHF may have been under-estimated.

Conclusion: It was found that hospitalization resulted in substantial costs for treatment of heart failure in South Korea, especially in patients with an acute heart failure event. Prevention strategies and appropriate management programs that would reduce both frequency of hospitalization and length of stay for patients with the underlying risk of heart failure are needed.  相似文献

Abstract

The article aims to analyze the forms of engagement generated from the endorsement of products by digital influencers on Instagram, considering the characteristics of their online posts. A qualitative approach was used to investigate digital influencers’ posts based on semiotic image analysis and the critical incidents technique. The results reinforced that digital platforms enable distinct forms of engagement by establishing new configurations that affect relationship marketing and promotion strategies. In particular, on Instagram, the development of engagement can involve four participants who play different social roles, expanding the process of value co-creation.  相似文献

We show that, in a minimum effort game with incomplete information where player types are independently drawn, there is a largest and smallest Bayesian equilibrium, leading to the set of equilibrium payoffs (as evaluated at the interim stage) having a lattice structure. Furthermore, the range of equilibrium payoffs converges to those of the deterministic complete information version of the game, in the limit as the incomplete information vanishes. This entails that such incomplete information alone cannot explain the equilibrium selection suggested by experimental evidence. We thank Atila Abdulkadiroglu, Hans Carlsson, Ani Guerdjikova and an anonymous referee for helpful comments. Part of this work was done while Asheim was visiting Cornell University, which hospitality is gratefully acknowledged.  相似文献

Performance Appraisal Systems: Determinants and Change   总被引:1,自引:0,他引:1  
Using establishment data from the Australian Workplace Industrial Relations Survey, this paper estimates the determinants of performance appraisal systems. The results indicate that performance appraisal is associated with workers having shorter expected tenure and greater influence over productivity. We argue these results reflect those circumstances in which the net benefits of performance appraisal are likely to be greatest. The results also show that complementary human resource management practices, such as formal training and incentive pay, are associated with an increased likelihood of performance appraisal, but that union density is associated with a reduced likelihood of performance appraisal.  相似文献

Product placements in entertainment media are increasing, particularly in content targeted to adolescents. This marketing communication tactic is examined in the context of media socialization and individual differences in brand consciousness. The relative influence of commercial media (TV, radio, movies, online) and perceived peer and parent brand consciousness on US adolescent brand consciousness is assessed, as well as differences in how low and high brand‐conscious adolescents view product placements. Awareness, liking and perceived effects of product placements on self and others (third‐person perception) were measured. Results of hierarchical multiple regression analyses show that movies and perceived parent and peer brand consciousness were positively related to adolescent brand consciousness. Those adolescents considered to be highly brand‐conscious were also those who were most aware of and favourable towards product placements. All adolescents demonstrated third‐person perception of media effects in that they considered others to be more influenced by product placements than themselves, with peers influenced more than friends. Highly brand‐conscious teens perceived the greatest effects of product placements on their own and others’ buying behaviours, yet low brand‐conscious teens revealed the largest gap in perceptions of impact on self vs. peers. The results are discussed in view of media effects; ramifications for marketers and public policy makers are also appraised.  相似文献
