The winding down of military operations in Iraq and Afghanistan has prompted a scholarly debate around America’s evolving strategic role and posture in the broader Middle East. Allegedly, its isolated geographical position and “seapower” condition would allow the US to behave as an “offshore balancer”, by pulling back militarily, retreating from alliances and formal security commitments and relying on the different regional powers to balance each other. However, it remains unclear to what extent a seapower like the US would be able to effectively manipulate the balance of power in the Middle East from offshore. An examination of US strategy in the Middle East from 2009 to 2015 suggests that the main puzzle Washington confronts is not so much whether to retreat offshore or remain engaged onshore, but rather to work out the terms of onshore engagement. As this article shows, current US strategy in the Middle East revolves around the need to reconcile two seemingly contradictory sets of pressures. The first is that war fatigue, financial pressures and the ongoing reorientation of military-strategic resources towards the Asia-Pacific theatre do require that the US cuts back on its engagement elsewhere, including in the Middle East. The second relates to Washington’s deep-seated conviction that there is a direct correlation between US forward presence and the preservation of a favourable balance of power in the Middle East, which is itself critical to the security of other regions, including the Asia-Pacific. By discussing the relationship between seapower and forward presence, this article places US strategic retrenchment in the Middle East in perspective. In particular, the article transcends the rather vague notion of “balancing” and concentrates on US perceptions about which geographical areas in the Middle East need to be balanced, and how, i.e., through which alliances, instruments and policies.  相似文献

Municipalities and regions are often used as an object of tourism analysis at the subnational level. This occurs because administrative borders are used to implement tourism policies and collect statistical information. However, administrative boundaries may not always be suitable for studying tourism destinations at a local level. Sometimes, particularly in high-density tourism destinations, several differentiated tourism areas occupy a single municipality; tourism areas may, and often do, extend beyond municipal boundaries and tourism destinations may not occupy the whole of the municipal area. As such, a new level of analysis is often required: the micro-destination. There are few tourism concepts as imprecise as that of the destination. Therefore, the process of identifying and establishing the boundaries of a micro-destination is by no means a straightforward one. This paper presents six criteria for establishing the boundaries of this type of tourism area. Of these six, the two primary criteria used are: the concentration of tourism establishments; and tourism typologies and supply characteristics. These criteria have been applied as part of a pilot study in the Canary Islands. Statistical information for nine micro-destinations is generated using the geolocation of tourism establishments together with information obtained from both supply-side and demand-side surveys.  相似文献

This paper examines the qualitative, quantitative, and geographical evolution (1987–2012) of the Blue Flag campaign and accreditation process in Spain, a leading coastal tourism destination heading the list of awards. The standard Blue Flag criteria for crowded, developed beaches are now adapting to new demands for natural beaches, but they still fail to capture essential sustainable tourism features, such as limiting user numbers, or preserving and restoring sand ecosystems. Given these shortcomings, some destinations are moving to alternative awards with a higher environmental commitment, such as EMS, ISO14001, and Eco-Management and Audit Schemes (EMAS). A cluster analysis of Blue Flag data for 983 beaches in Spain over 26 years revealed different behaviour patterns: established tourist areas that have always opted for the Blue Flag programme; tourist areas that adopted the Blue Flag early on but replaced it with ISO14001 and EMAS; recently developed destinations applying for the award to boost their tourism promotion; and tourist areas with no well-defined policy that have opted intermittently for Blue Flag. These profiles illustrate the different policies of Spain's Autonomous Regions, and they are useful for tourism managers to verify whether their destination's behaviour pattern contributes to sustainable tourism and matches strategic policies they have designed for them.  相似文献

Social networks are becoming increasingly important for consumers, especially in the context of sport, where the service experience is highly intense. Few studies have combined subjective event performance variables and social network variables to analyze social network content sharing by sports practitioners. This article investigates the use of social networks in relation to sporting events. An empirical study examined the role of social network variables and sporting event performance variables in social media use. The sample consisted of 410 triathletes (72.2% male) aged between 18 and 66 years (mean 37.03 ± 8.62). Four analyses were performed using fuzzy‐set qualitative comparative analysis to examine the causes of sharing comments through social media, sharing photos and videos on social media, participant satisfaction, and word‐of‐mouth (WOM). The event's general image was a necessary condition in all cases. The combination of participants’ satisfaction and positive event image and the combination of social network use and positive event image lead to social network content sharing by athletes. The combination of positive event image and participant satisfaction leads to a positive WOM.  相似文献

The aim of this paper is to review the usefulness of the software CAQDAS QSR—Nvivo-6 in a PhD. Thesis, which consisted of finding the long-term psychological effects of experiences of imprisonment and torture for political reasons in their Chilean survivors. For this research, it was created and administered an in-depth interview to 60 survivors, from which outcome was 9900 paragraphs, coded into 784 categories. The software QSR Nvivo-6 threw a report of frequencies, which were compared quantitatively using Pearson’s χ 2 square test and cluster analysis. We conclude that the software facilitates the development of qualitative thematic content analysis, simplifying the coding, analysis and display of data. In Addition, it is very useful when working with large quantities of information, promoting the reliability and validity of studies. However, other aspects are also required to ensure the rigor of a qualitative study.  相似文献

Since Poland has become a member of the European Union, free market activities have increased dramatically. The purpose of this study is to explore university students' perceptions of personal selling as a career in Poland. Using logistic regression and Z-test methodologies, we analyzed the perceptions of 114 students. The results confirm the findings of previous studies that personal factors play a significant role in predicting students' perception of sales profession as a career. The findings presented in this study show that Polish students have a biased perception about sales as a career; however, interestingly, few dimensions show a significant effect. Understanding students' perceptions of the sales profession will help corporate recruiters achieve their goals by selecting those students most likely to excel in sales careers.  相似文献

Opening the black box: Finding the source of cost inefficiency   总被引:2,自引:0,他引:2  
Parametric and nonparametric procedures are used to identify the apparent source of cost inefficiency in banking. Inefficiencies of 20–25% from earlier studies are reduced to 1–5% when, in addition to commonly specified cost function influences, variables reflecting banks’ external business environment and industry indicators of “productivity” are added. These productivity indicators explain most of the reduction in bank operating cost over 1992–2001 and was 5 times the reduction in the dispersion of inefficiency. Inefficiency appears stable over time because it is small relative to industry-wide cost changes occurring concurrently and because technology dispersion is imperfect.
