According to recent research, countries may have a positive image from a tourism perspective, but they may be seen as lacking from an economic or political viewpoint. As governments and destination management organisations spend large sums of money in promoting tourist attractions, the question of whether these activities also influence other aspects of a country's image becomes relevant. The objective of the research is to determine the effect of tourism promotions on the image of the country and that of the destination as two separate concepts, in the case of Israel, a country subject to continuous conflicts. A 2?×?2 quasi-experimental design is utilised to investigate the influence of tourism promotional brochures. Additionally, a comparative perspective is used to determine whether people from diverse countries and backgrounds may be affected differently by the same information. The findings confirm that tourism brochures influence not only the image of the destination, but also that of the country. These effects are found to be different for respondents from the two different countries compared. The article focuses on understanding how tourism communication strategies may also be used to improve the image of a country, with potential benefits for international marketing and international relations.  相似文献

In this study, we develop a conceptual bioeconomic model of floriculture production with aesthetic benefits, wherein optimal decision rules depend on an intertemporal economic objective to maximize profits subject to economic and biological processes. Necessary conditions of the model identify optimal trajectories (e.g., simultaneous, single, or cycling controls) that define decision rules and economic thresholds for profit maximizing growers producing crops with aesthetic attributes. The necessary conditions also highlight intertemporal trade‐offs between aesthetic benefits and expected future net benefits of arthropod stocks, which have important policy implications. The model is applied to the greenhouse production system of ivy geranium.  相似文献

John Blundell's ideas for structural change could undermine the strengths of British policing. Nevertheless, there is a need for decentralisation and more local control.  相似文献

Trade liberalisation has played a critical role in advancing peace and prosperity. Differences on agriculture have been the major impediment to a future multilateral trade round. The recent agreement on agriculture at the WTO meetings in Geneva may signal a breakthrough in that sector. This article analyses the benefits of recent trade agreements and examines the prospects for future ones. It also presents an alternative framework for advancing trade, the Global Free Trade Association.  相似文献

The rapid advances in technology with declining costs of hardware is expected to widen the market for computers. One of the interesting balances for vendors to achieve is keeping users happy with increases in price performance, usually with lower unit costs. One way to achieve this objective is by satisfying users and meeting their needs. Users have many different needs, however, and it may be very difficult to prioritize them since many of the needs are partially mutually exclusive. For example, the promotion of one need, low response time, would be at the expense of another need, low cost. Therefore, mini/micro vendors and users could use a model that will prioritize needs and measure how satisfied users are with specific computer systems as compared to others. Similarly, the same information may be very useful to current and future computer users for system selection. Accordingly, the main purpose of the present study is to provide vendors and users of mini/micro computers with a discriminant model. This model classifies correctly 93% of the successful systems. Thus it can be used for system selection by users and for system design by vendors.  相似文献

Los autores ofrecen nuevos datos empíricos sobre la volatilidad en los ingresos y en el mercado de trabajo (incluyendo entradas y salidas del empleo) de los jóvenes en Europa durante la Gran Recesión. Los datos de EU‐SILC para el periodo 2004–2013 revelan grandes disparidades al respecto entre los países europeos. La Gran Recesión incrementó la volatilidad entre los jóvenes. Mediante un ejercicio de descomposición de la varianza se observa una mayor rotación laboral en el sur de Europa. Según un modelo de efectos fijos, un mayor nivel de prestaciones de desempleo y de protección del empleo se asocia con una reducción de la volatilidad.  相似文献

Recent economic and organisational changes have fostered an increasing diversification of the workforce, among whom freelancers are an under‐represented population in the literature. This study aimed at examining the role of protean and boundaryless career, professional commitment, and employability activities in fostering freelancers' subjective career success. Data were collected via an online survey among a sample of 425 Italian freelancers and analysed through structural equation modelling. Results partially confirmed several hypotheses: higher self‐directed career management and boundaryless mindset predicted higher employability activities and professional commitment; moreover, employability and professional commitment acted as mediators between career attitudes and subjective career success. The study provides support for the importance of such variables to freelancers' career success, as well as for the significance of protean and boundaryless careers among nontraditional occupational groups. Interventions aimed at fostering such attitudes could support freelancers in improving their attainment of professional progress and perception of career success.  相似文献
