Special issue: Journal impact factors. [editorial]

C. Ryan and S. Page, "Special Issue: Journal impact factors", Tourism Management, Vol. 51:298-299, December 2015. Available online at: https://doi.org/10.1016/j.tourman.2015.05.014As many readers will be aware, Tourism Management has not hosted Special Issues since 2000 when it ran a feature on the Competitive Destination and the recent Virtual Special Issue that collated the Progress in Tourism Management: The first six years 2007-2013 review papers. Our decision to suspend Special Issues reflects the huge growth in submission and the volume of papers the Journal now publishes. In 1996 the journal was publishing around 60 papers a year from about 250 to 300 submissions. In 2014 this will have grown to over 900 submissions and approximately 130 papers published with acceptance rates of around 15–18%. This exponential growth in the journal's popularity means that space for Special Issues has been at a premium while the prime consideration has been the timely publication of cutting edge scholarly papers. Accompanying these changes has been a rise in the interdisciplinary content of much of the work now being published in the journal. An important ethos of the journal which the Editors espouse is that Tourism Management remains a broad-based journal that embraces that interdisciplinarity and encourages scholarly debate on papers that occurs from time to time in Rejoinders we publish while additionally encouraging the publication of novel and controversial topics.Peer reviewe

Air Passenger Duty and Outbound Tourism Demand from the United Kingdom

On November 1, 1994 an Air Passenger Duty (APD) was introduced in the United Kingdom, and since, this tax continues to be controversial. This article examines the effect of the ADP on UK outbound tourism demand for 10 international destinations. An autoregressive distributed lag model is developed and income, price, and tax elasticities are estimated. The income and price elasticities obtained, ranged between 0.36 and 4.11 and −0.05 and −2.02, respectively. The estimated tax elasticities suggest that the implementation of APD had a negative effect on UK outbound travel for five destinations and the demand is inelastic to changes in taxes although the magnitudes vary across destinations. The general message is that although the stated objective of APD is to reduce travel and associated carbon emissions, the effectiveness of APD, however, has been marginal; travelers are prepared to pay more in the main to maintain their demand

Maritime tourism and terrorism: Customer perceptions of the potential terrorist threat to cruise shipping

Maritime terrorism is a neglected area of research in tourism, particularly the use of scenario planning to understand potential threats to the cruise industry. Since the events of 9/11, terrorism, and the threat of terrorism, has become a major concern within the tourism industry. This article analyses tourist perception of perceived terrorist threats given that many ships are American owned. Using the scenario analysis presented by Greenberg, Chalk, Willis, Khilko, and Ortiz, this study suggests that an attack on a cruise ship is a distinct possibility. Indeed, 44% of respondents questioned perceived the possibility of a terrorist attack on a cruise ship to be likely despite the fact that safety and security is seen by the industry as a 'hallmark' of cruising. Differences in attitude among potential passengers revealed a high level of confidence in the cruise ship companies. This finding is particularly marked among more experienced cruise ship passengers. However, this did not necessarily preclude the possibility of security measures being improved. All passengers appeared generally resigned to the fact that risk is associated with travel in the twenty-first century and welcomed any efforts by cruise shipping companies to improve safety and security. © 2012 © 2012 Taylor & Francis

Progress in tourism and destination wellbeing research

A proliferation of research in recent years has revealed a myriad of relationships between tourism and the concept of wellbeing. These include health benefits of visiting tourist destinations, a product focus on wellness and maintaining good health. Broader interpretations emphasize the complex ways in which tourism can influence the emotional, psychological, cognitive and spiritual dimensions of wellbeing, both for tourists and for destination communities. This study reflects an emerging paradigm shift that incorporates a deeper appreciation of the benefits derived at the destination level from a focus on health and wellbeing. The study highlights three key perspectives, namely the tourist, the destination community and the destination itself. The study concludes that research in this area is critical to the future development, management and marketing of sustainable and competitive destinations with the wellbeing of tourists, their destination host communities, and the overall destination experience, critical to their ultimate success

Soluble silicon patterns and templates:calcium phosphate nanocrystal deposition in collagen type 1

Patterned mineralisation is a feature of many hard-tissues. The impressive mechanical properties exhibited by such tissues can be, in part, attributed to the patterned deposition of mineral within the organic matrix. Although not thermodynamically favourable, the deposition of calcium phosphate based mineral within collagen fibres occurs in vivo in bone and dentine. As a consequence, numerous researchers have investigated how matrix proteins may be conditioned to enable patterned mineral deposition to recapitulate the structures found in nature. In this study, we have demonstrated that this patterned mineralisation of collagen type I may be induced simply by the pretreatment of the collagen with orthosilicic acid (OSA). The OSA treatment of the collagen resulted in a structural change to the collagen fibres, modifying fibril diameter and changing the kinetics of fibre formation. NMR demonstrated that the OSA preferentially located to the termini of the procollagen fibrils, thereby templating the formation of apatitic calcium phosphate crystals within the collagen fibrils (as shown using TEM, EDX and SAED). This work demonstrates how simple inorganic ions can have potent effects on structuring biological precipitates and suggests why trace quantities of silicon ions are essential to the formation of healthy hard tissues

Nanostructure of CaO-(Na2O)-Al2O3-SiO2-H2O gels revealed by multinuclear solid-state magic angle spinning and multiple quantum magic angle spinning nuclear magnetic resonance spectroscopy

(Calcium,alkali)-aluminosilicate gel frameworks are the basis of modern cements and alkali-activated materials for sustainable infrastructure and radioactive waste immobilization and also find application in glass alteration, mineral weathering, and zeolite synthesis. Here, we resolve the nanostructure of these gels that dictates mass transport, solubility, and mechanical properties. The key structural motifs comprising hydrous (calcium,alkali)-aluminosilicate gels are identified via 17O, 23Na, and 27Al triple-quantum magic angle spinning and 29Si magic angle spinning nuclear magnetic resonance spectroscopy of a novel class of stoichiometrically controlled 17O-enriched multiphase gels. Increased Ca content promotes low-Al, high-Ca chain-structured “C-S-H-type” products exhibiting significant nanostructural ordering, low levels of chain cross-linking, predominant Ca coordination of nonbridging oxygen atoms, and an increase in proton association with CaO layers to form Ca–OH sites. Al substitution is identified in multiple sites in the silicate chains, including cross-linking, bridging, and pairing tetrahedra. Increased Al content increases the proportion of cross-linking sites and gel disorder. The large increase in SiIV–O–AlIV sites increases the relative amounts of Na+ and AlV species charge-balancing AlO4– tetrahedra and results in the formation of an additional disordered low-calcium, framework-structured alkali aluminosilicate (“N-A-S-H-type”) gel, with high Al and Na contents. Changes in bulk composition significantly alter the nanostructures of the C-S-H-type and N-A-S-H-type gels. Mean SiIV–O–AlIV bond angles for each type of AlIV site environment are highly consistent, with compositional changes dictating the relative proportions of individual AlIV species but not altering the local structure of each AlIV site. These findings reveal the molecular interactions governing the (calcium,alkali)-aluminosilicate gel nanostructure, which are crucial in controlling material properties and durability
