This paper aims to investigate the impact of special and alternative forms of tourism on the sustainable development of tourism destinations,revising the traditional position of tourism development and establishing sustainable development as the only solution to tourism progress of travel destinations.The study includes conceptual approaches to the term tourism,sustainable development and specific and alternative forms of tourism and delves into theoretical approaches that are the bridging of these three central research questions.This is followed by in-depth research through policy analysis of central institutions and regional development stakeholders,as well as further analysis of sustainable development through special and alternative forms of tourism.Key tourism models and theories offer a further understanding of the natural“enemies”and“allies”of sustainable development and how they contribute to its necessity or development.Through a survey and a case study of travel destinations,we conclude the need to couple the term tourism development with sustainable development which is rooted in the healthy coexistence of residents and visitors with respect to the environment,local culture and productive-controlled economic growth. 展开更多

Alzheimer's disease(AD) is an irreversible and progressive neurodegenerative disease as well as the most common form of dementia. It usually affects the older population, but early onset AD is still possible(Ritchie et al., 2015). Recent studies propose that AD is a middle-life disease(Ritchie et al.,2015). 展开更多

The purpose of this paper is to analyze the reception of Wagner's approaches to Greek antiquity by Greek musicologists and composers which took place at the first half of the 20th century. Wagner's such readings were parts of wider narrations of archeology and how Greeks perceived their past.This research is largely based on primary sources of that time; its arguments construct two levels of critique: (1) Admiration (the 'proper' aesthetic examples are German models, as exemplified in Wagner's work); and (2) "Hellenism" as a means to distancing from Wagner (The past of ancient Greece is still believed to be better understood by the Greeks). The principal conclusions are: (1) Wagner's views were admired because Wagner's example (ancient culture) should also be an example for Greek composers; and (2) Wagner's views were judged on the grounds of: Ideology: the expression of the "soul"; the theory of "historic continuity"; the balance between music, poetry, and dance; Wagner gave superiority to music, modem Greeks (should) give a predominant role to language as a means of expression in an ancient drama, or achieve a balance among the three arts of music, poetry, and dance. 展开更多

Nowadays, the most prominent risk assessment techniques are founded on the values of measuring and controlling the frequency and the consequences of risks in order to assure an "acceptable level" of "safeness" mainly in the lines of environmental, health and hygiene and port product issues. This paper initially introduces risk assessment approaches within the emerging role of ports Thereafter, it qualitatively assesses their potential for ports by discussing issues challenging every safety and security approach within the maritime industry such as proactiveness, organization, transparency, cost-effectiveness and, when possible, calibration to specific experiences. Moreover, an empirical study was conducted in order to provide evidence for formal risk assessment for safety and security in the main Greek port container terminals of Piraeus and Thessaloniki. The empirical research is based on in-depth semi-structured interviews with the administrations of container terminals. The results include important findings, regarding the likelihood of appearance of certain risks and their perceived severity in Greek container terminals. The collected answers and their analysis are also important for confirming the suggested theoretical formal risk assessment framework for ports. 展开更多

Cells use various RNA (Ribonucleic Acid) regulatory mechanisms in order to temporally and coordinately influence the rate of protein synthesis. A deeper understanding of the dynamics of RNA regulation can ultimately bridge the gap between transcriptional control and protein expression. The nonlinear process of RNA-Protein Interaction (RIP), which can be viewed as the RNA analog of the better-known chromatin immunoprecipitation application (CHIP) plays a crucial role in post-transcriptional regulation of gene expression. While ChIP identifies DNA (Deoxyribonucleic Acid) targets of DNA-binding proteins in their cellular context, RIP can be used to identify specific RNA molecules associated with specific nuclear or cytoplasmic RNA-binding proteins. In this paper, a stochastic model in BioAmbients calculus for the protein synthesis and activation through RIP process is presemed. 展开更多

Unfortunately, though, it seldom takes advantage of the new technologies and capabilities offered by the modern World Wide Web. In this article, we present an interactive online platform that provides users with learning activities for students of English as a foreign language. The platform focuses on using audiovisual multimedia content and a user experience (UX) centered approach to provide learners with an enhanced learning experience that aims at improving their knowledge level while at the same time increasing their engagement and motivation to participate in learning. To achieve this, the platform uses advanced techniques, such as interactive vocabulary and pronunciation assistance, mini-games, embedded media, voice recording, and more. In addition, the platform provides educators with analytics about user engagement and performance. In this study, more than 100 young students participated in a preliminary use of the aforementioned platform and provided feedback concerning their experience. Both the platform’s metrics and the user-provided feedback indicated increased engagement and a preference of the participants for interactive audiovisual multimedia-based learning activities.</span> </p> 展开更多
