Islands and destination image: the case of Ios

This study was conducted to identify the image of Ios as a tourist destination as perceived by the visitors, in order to contribute to the formation of an effective marketing plan. The strengths and weaknesses of the image of Ios were measured and presented, accompanied with a number of recommendations. The findings revealed that Ios has a very strong destination image as a party island, with the majority of the visitors being international young students coming to enjoy the relaxing atmosphere and the party mood of the island. As a result, Ios needs to strengthen its image compared to other islands or destinations which offer the same product, by promoting its competitive advantages, such as; the nightlife, the relatively low prices, the relaxing atmosphere and the friendliness of the locals

The role of visual media in religious tourists' destination image, choice, and on-site experience: the case of Tinos, Greece

Although visual media are known to influence the image people have of tourism destinations worldwide, only a few studies have examined their role in the context of religious tourism. This study explores the role TV news and documentaries play in religious tourists’ destination image, choice and on-site experience. Ethnographic research (31 participant observations and 38 in-depth interviews) was conducted in two organized coach trips to the sacred island of Tinos, Greece. The findings suggest that broadcasted images of the holy icon, the leading politicians, and the performing religious crowd shape the image of Tinos and influence visitation patterns. Additionally, the visual projection of religious tourists’ offerings appears to condition peoples’ on-site experience. The theoretical and practical implications of the study are also discussed

Elastic response of [111]-tunneling impurities

We study the dynamic response of a [111] quantum impurity, such as lithium or cyanide in alkali halides, with respect to an external field coupling to the elastic quadrupole moment. Because of the particular level structure of a eight-state system on a cubic site, the elastic response function shows a biexponential relaxation feature and a van Vleck type contribution with a resonance frequency that is twice the tunnel frequency $\Delta/\hbar$. This basically differs from the dielectric response that does not show relaxation. Moreover, we show that the elastic response of a [111] impurity cannot be reduced to that of a two-level system. In the experimental part, we report on recent sound velocity and internal friction measurements on KCl doped with cyanide at various concentrations. At low doping (45 ppm) we find the dynamics of a single [111] impurity, whereas at higher concentrations (4700 ppm) the elastic response rather indicates strongly correlated defects. Our theoretical model provides a good description of the temperature dependence of $\delta v/v$ and $Q^{-1}$ at low doping, in particular the relaxation peaks, the absolute values of the amplitude, and the resonant contributions. From our fits we obtain the value of the elastic deformation potential $\gamma_t=0.192$ eV.Comment: 19 pages, 5 figure

Dynamical models for sand ripples beneath surface waves

We introduce order parameter models for describing the dynamics of sand ripple patterns under oscillatory flow. A crucial ingredient of these models is the mass transport between adjacent ripples, which we obtain from detailed numerical simulations for a range of ripple sizes. Using this mass transport function, our models predict the existence of a stable band of wavenumbers limited by secondary instabilities. Small ripples coarsen in our models and this process leads to a sharply selected final wavenumber, in agreement with experimental observations.Comment: 9 pages.

Design agency:prototyping multi-agent systems in architecture

This paper presents research on the prototyping of multi-agent systems for architectural design. It proposes a design exploration methodology at the intersection of architecture, engineering, and computer science. The motivation of the work includes exploring bottom up generative methods coupled with optimizing performance criteria including for geometric complexity and objective functions for environmental, structural and fabrication parameters. The paper presents the development of a research framework and initial experiments to provide design solutions, which simultaneously satisfy complexly coupled and often contradicting objectives. The prototypical experiments and initial algorithms are described through a set of different design cases and agents within this framework; for the generation of façade panels for light control; for emergent design of shell structures; for actual construction of reciprocal frames; and for robotic fabrication. Initial results include multi-agent derived efficiencies for environmental and fabrication criteria and discussion of future steps for inclusion of human and structural factors

A Review of Drowning Prevention Interventions for Children and Young People in High, Low and Middle Income Countries.

Globally, drowning is one of the ten leading causes of child mortality. Children aged <5 years are particularly at risk, and children and young people continue to be overrepresented in drowning statistics. Accordingly, evidence informed interventions to prevent children drowning are of global importance. This review aimed to identify, assess and analyse public health interventions to reduce child drowning and investigate the use of behavioural theories and evaluation frameworks to guide child drowning prevention. Thirteen databases were searched for relevant peer reviewed articles. The systematic review was guided by the PRISMA criteria and registered with PROSPERO. Fifteen articles were included in the final review. Studies were delivered in high, middle and low income countries. Intervention designs varied, one-third of studies targeted children under five. Almost half of the studies relied on education and information to reduce drowning deaths, only three studies used a multi-strategy approach. Minimal use of behavioural theories and/or frameworks was found and just one-third of the studies described formative evaluation. This review reveals an over reliance on education and information as a strategy to prevent drowning, despite evidence for comprehensive multi-strategy approaches. Accordingly, interventions must be supported that use a range of strategies, are shaped by theory and planning and evaluation frameworks, and are robust in intervention design, delivery and evaluation methodology. This approach will provide sound evidence that can be disseminated to inform future practice and policy for drowning prevention

Counterpoint: The Musical Analogy, Periodicity, and Rural Urban Dynamics

Every thesis calls for its antithesis, and every revolution prompts a counterrevolution—this takes place within the same generation as well as across intergenerational oscillations (Gassett 1958, Sennett 1974). Enlightenment thinkers were critical of the Humanist tradition of analogical thinking—their own encyclopedic enthusiasm was intent upon creating a lexicon of the world, an ambition that has been assiduously realized in contemporary Geographic Information Systems (GIS) and empirical attitudes toward industrial agriculture and managerial urbanization. However, languages are comprised of two parts—a lexicon and grammar—and analogical thinking, focused as it is on seeing relationships between parts, is particularly well suited to provide conceptual frameworks for contextual design. To harness the power of polemics, we can anticipate that at least two conceptual paradigms, polarities to one another, are needed at any given moment—and that these are best conceived of as, to paraphrase Sébastien Marot, “opposite, but not exclusive of one another” (Marot 2003). Further, as any given analogy will inevitably prompt justifiable reactions against it, I propose that we work between those two oldest and most enduring architectural analogies: the biological analogy (on growth and form) and the musical analogy (on composition and form). Of these, the biological analogy is clearly in ascendancy—see, for example, Philip Steadman’s seminal The Evolution of Designs: The Biological Analogy in Architecture and the Applied Arts (Steadman 1979, 2008) or Lynn Margulis’ The Basic Unit of Life (Margulis 2010). Hence, this sustained reflection on the musical analogy, made with a view to its instrumentality for composing rural urban dynamics in relation to existing landscapes

The role of leptin in the respiratory system: an overview

Since its cloning in 1994, leptin has emerged in the literature as a pleiotropic hormone whose actions extend from immune system homeostasis to reproduction and angiogenesis. Recent investigations have identified the lung as a leptin responsive and producing organ, while extensive research has been published concerning the role of leptin in the respiratory system. Animal studies have provided evidence indicating that leptin is a stimulant of ventilation, whereas researchers have proposed an important role for leptin in lung maturation and development. Studies further suggest a significant impact of leptin on specific respiratory diseases, including obstructive sleep apnoea-hypopnoea syndrome, asthma, COPD and lung cancer. However, as new investigations are under way, the picture is becoming more complex. The scope of this review is to decode the existing data concerning the actions of leptin in the lung and provide a detailed description of leptin's involvement in the most common disorders of the respiratory system
