Effects of Immersive Experiences in Green Tourism on Behavioral Intentions of Young Tourists

Green tourism is a growing industry with large development potential. Thus, it is necessary to explore how immersive experiences drive its development in an innovative form of tourism. In this study, the behavioral intentions (BI) of young tourists were investigated by a technology acceptance model (TAM). Meizhou, a city with abundant green tourism resources, was chosen as the study area to formulate a BI model for immersive experiences in green tourism. The hypotheses were proposed and tested based on the results of a questionnaire survey and statistical analysis. The results revealed that tourists’ perceived usefulness (PU) and attitude toward using (ATU) significantly affected their BI. PU played a mediating role between perceived ease of use (PEOU) and BI. Appropriate recommendations regarding the development of immersive experiences in green tourism in Meizhou were made to enrich the BI model’s application. The research results provide an important reference for urban governance.

Multi-criteria analysis to evaluate tidal energy potential in France

France benefits from an important tidal energy resource, with the second largest potential in Europe, and one of the biggest in the world. In addition, France has an important industrial and academic fabric, with several tidal developers, shipyards, and research centers, creating, theoretically, an attractive environment. However, though some tidal turbines already installed, such as Sabella demonstrator at Ouessant Island, or Guinard energy turbine in the Etel river, the sector still has a large development potential. One limitation of such a development is the lack of available data to assess the total potential. Previous studies mainly focused on the most energetic sites, such as the Alderney Race or the Fromveur Passage, while other sites are neglected. Yet, those sites, such has rivers or estuaries, offer softer conditions, lowering the risks. Moreover, although identifying a suitable area for tidal array implementation requires technical criteria (maximum current velocity, water depth, installable potential, etc.), it should also consider other aspects such as ecological indicators (migratory fishes, specific habitats, etc.), regulation specificities (Natura 2000, ZNIEFF, etc.) or human activities conflicts (fishery, UXO, etc.). On top of that, socioeconomic indicators, such as potential local content or partnerships with relevant academic stakeholders, are encouraged by authorities, and must be accounted for.
 Hence, this study proposes an extensive multi-criteria analysis methodology, to assess tidal energy potential of ten sites in France, including five nearshore locations (Alderney race, Fromveur passage, Raz-de-Sein, Raz-Barfleur, Paimpol-Bréhat), and five estuaries, river or similar (Gironde estuary, Gulf of Morbihan, Adour river, Etel river, Arcachon Bay). The analysis is limited to ten sites, selected based on a pre-screening analysis, which will be detailed in the study.
 The different criteria used will be presented, including their weight to the final score which reflect their importance during project development, and the 3-level grading system used to discriminate sites. The methodology developed to assess full-time equivalent employments created by a tidal array, using world input-output tables and other economic parameters will also be detailed. A specific focus will be proposed on methodology used to assess the installable capacity, relying on data from MARS 2D model for nearshore sites and public data for the others.
 First analysis shows that Raz-de-Sein and Paimpol-Bréhat are the two most suitable sites for tidal arrays implementation, while the Alderney Race is the most energetic one. Those results are driven by high scores obtained by these sites in categories such as ecological or human activities. Direct, indirect, and induced employments created during construction and operational phase by each project are also calculated, as well as potential growth value added. Hypothesis and sensitivity to them will be discussed.
 This research was funded by the H2020 projet ELEMENT, grant number 815180.

Unmanned surface vehicle navigation through generative adversarial imitation learning

In the artificial intelligent and big data technology era, the marine industry among others is inevitably developing in this direction, aiming at becoming autonomous and completing tasks without relying on human involvement while providing safety. The technology of small unmanned surface vehicles (USVs) is relatively mature but with a large development potential and wide research interest expecting significant benefits such as safety and high efficiency in shipping and transportation systems. This article addresses these issues and utilizes an imitation learning algorithm to resolve autonomous navigation for USVs even in complex environmental conditions. We formulate the trajectory modeling as a data-driven imitation learning problem where we employ a state of the art imitation learning algorithm. Experiments are performed in a particular simulated environment tailored to match the specific weather conditions of the local area. The simulation results show the potential of the proposed imitation learning scheme to create advanced intelligent agents for USVs under real-world environmental settings, and USV actuation constraints that allow to predict trajectories with high accuracy and safety.In addition, we evaluated the method’s robustness in generating successful trajectories under environmental conditions that differed from those encountered during training, thereby promoting knowledge reusing without the need for retraining.

Measurement and Development of Park Green Space Supply and Demand Based on Community Units: The Example of Beijing’s Daxing New Town

In urban development, balancing the ecological services of park green space with residents’ daily life and recreational needs, achieving sustainable development is an important issue in urban construction. The satellite cities of megacities have large development potential and are suitable research objects. This paper takes the Daxing District of Beijing as the research target and measures the integrated level of supply and demand by selecting unique evaluation indicators by integrating various dimensions and using the improved coupled coordination model and indicators with an expanded selection range at the smallest administrative unit of Chinese community unit scale innovatively. The study shows that: (1) The spatial heterogeneity between the supply and demand of parkland in 85 community units in Daxing New Town is obvious, the overall performance conforms with “demand exceeds supply”, and the supply and demand are generally positively correlated. (2) The correlation degree of the matched supply and demand is analyzed, and it is found that 55 community units show a mismatch between supply and demand and 53 community units have a low level of coordinated development. (3) The superposition analysis shows that the comprehensive level of supply and demand decreases from north to south and from the center to the surrounding area. (4) According to the Daxing New City Park Green Space Coupling Coordination Relationship and Policy Document, we divided the community units in Daxing New Town into six types, and provided differentiated development suggestions. The results of the study can help to guide the sustainable construction of Daxing New City and provide a basis for the future construction of satellite cities in other megacities.

School-Based Exercise Programs for Promoting Musculoskeletal Fitness in Children Aged 6 to 10

Musculoskeletal fitness (MF) is a multidimensional construct that combines muscle strength, endurance, and power to allow for the performance of tasks against one’s own body weight or an external resistance. The aim of this study was to determine the effects of school-based programs on promoting MF in children aged 6 to 10. PubMed and Web of Science databases were used as searching tools. A total of 16 studies were included in a systematic review with primary school-based program interventions measuring at least one variable related to musculoskeletal fitness. Parameters for measuring explosive power, especially standing broad jump (SBJ), have a large potential for development throughout school-based programs. Long-lasting interventions did not necessarily improve MF; however, there were shorter interventions that caused the improvement in a larger number of parameters. Our findings imply that increased physical activity during a school week, together with improved lesson content, is crucial for MF development in this age group.

Evaluation of development potential of cropland in Central Asia

With population growth and rapid urbanization, agricultural land has become a relatively scarce resource. Given the vast land area in Central Asia, exploring the potential of agricultural land development in Central Asia is a realistic guide to the rational use of land and the alleviation of strained human-land relations and food shortage problems. In this study, Multi-criteria Decision Analysis (MCDA) and Analytic Hierarchy Process (AHP) were used to construct a cropland development potential evaluation system in Central Asia. The results showed that: (1) The development of current cropland basically adapts to local natural conditions in Central Asia. Suitable irrigated cropland is mainly located in areas with low elevation and close to water sources such as rivers and canals. Suitable rain-fed cropland is mainly located in the areas with flat terrain and sufficient rainfall. (2) The land resources of Central Asia still have a large potential for development: 1,008,000 km2 for the irrigated cropland and 217,124 km2 for the rain-fed cropland, mainly concentrated in Kazakhstan and Turkmenistan. The final evaluation results on a province-level scale presented in this study provide a direct and effective reference for future cropland development in Central Asian countries.

Structural and optical characterization of nanometer sized MoS2/graphene heterostructures for potential use in optoelectronic devices

Two-dimensional (2D) transition metal dichalcogenide (TMD) semiconductors, with MoS2 as the most widely researched one, have large potential for development of novel devices. This calls for scalable and controllable fabrication of TMD monolayers and their heterostructures with high-quality interfaces, controllable stack orientation and pristine properties. Molecular Beam Epitaxy (MBE) allows the growth of 2D van der Waals materials and offers unparalleled control of cleanliness and growth parameters. However, these advantages are limited by eligible growth substrates, which are often incompatible with the desired application. Here we show the growth of a heterostructure based on nanometer sized MoS2 islands on a macroscopic graphene sheet on Ir(111) and the subsequent transfer of the heterostructure to a Si wafer. The heterostructure is delaminated from the substrate by a two-step electrochemical process involving a sacrificial PMMA layer to ensure efficient transfer. Detailed scanning probe and spectroscopic characterization at different stages of the process confirm the high sample quality, which is maintained throughout the procedure. This method remedies the substrate constraints imposed by MBE and allows to harness its quality and tunability for applications in photonics, electronics and quantum technology.

Game over or play again? Deploying games for promoting water recycling and hygienic practices at schools in Ethiopia

Worldwide, every year 525 000 children under the age of five die from diarrhoea. The simple act of washing hands with soap and water can prevent more than one-third of diarrhoeal disease cases. In the densely populated urban areas of the developing world, handwashing wastewater is commonly discharged to the environment without any treatment, creating unhygienic situations and breeding places for different vectors and wasting a valuable resource. However, this relatively clean wastewater can be treated and reused using simple technological solutions. The objective of our water innovation is, therefore, twofold: improving children’s health through stimulating handwashing at schools while at the same time demonstrating the feasibility of water conservation through low-tech, nature-based treatment and safe reuse of handwashing wastewater for irrigation and toilet flushing. To enhance the intrinsic motivation of children and school staff to adopt this innovation, four educational games were developed drawing on theories used in gamification of learning, such as social learning theory and engagement theories. This paper provides an overview of the games and the main results of the game testing. For promoting hygiene among school children, a board and a card game were developed based on the F-diagram – commonly used by water and sanitation practitioners to illustrate the main routes for pathogen transmissions from faeces. In addition, the system linking handwashing wastewater collection, treatment and reuse for irrigation and toilet flushing was simulated by the development of two board games which targeted school children, school staff and the operators of the treatment system. The prototypes and final versions were tested in two schools in the Oromia region in Ethiopia – while the treatment system (constructed wetland) for handwashing wastewater is located in one school. Children that play-tested the games were generally enthusiastic and eager to play repeatedly, which demonstrated that board and card games are appropriate tools to engage with this young target group. We conclude that there is a large potential for development, use, and upscaling of educational games for more sustainable WaSH interventions.

Baby Boom generation in the online banking market in Europe

The Baby Boom generation, i.e. persons born between 1944 and 1963, constitutes over one fifth of the total European population, which makes it a significant segment of consumers. The important feature of this generation is their high trust in the banking system, which is one of the conditions for adapting technological changes in the areaof banking service distribution, including the acceptance of the internet banking (IB). In 2018, the average of 37.1% Baby Boomers used IB, which demonstrates that this distribution channel still has a large potential for development. There are distinct differences among European states regarding the scope of the internet usage for banking services by persons aged 55–74. The aim of this study is to define the structure of IB market for the European Baby Boom generation according to social and demographical characteristics (education and gender). The study is based on Eurostat’s corresponding data for 2018.The analysis of the structure of the IB market has been based on the gender and the level of education of its users, adopting one of the methods of cluster analysis, the Ward method. The analysis demonstrates that Nordic countries and the Netherlands are the European leaders in terms of IB usage among Baby Boomers, whereas the lowest percentage of IB usage among Baby Boomers has been observed in the Balkan and Southern Europe-an countries, e.g. Turkey and Italy. Among the analysed social and demographic characteristics, education differentiates the selected groups of states to a larger extent than gender.

Creating demand for the tourist product during the implementation of geotourist project for post-mining objects

AbstractThe experience of recent years shows that geotourism in post-mining objects has got a large development potential due to, among others, moving away from the typical museums to modern tourism products much more engaging visitors and the transition from the idea of 3S (sun, sand, sea) for 3E (experiment, excitement, education) and 4H (heritage, handicraft, habitat, history). In the article the specifics of the tourism product in projects related to the adaptation and using of post-mining objects and sites were presented. The article presents an assessment of the possibility of building a branded tourist product based on the relics of the mining industry in the context of the development and implementation of subsequent phases of the project consisting in making these relics available to tourists. The examples of completed projects, among others, in Poland and Germany were used. The division of the primary and secondary value of the geotourist project and the activities affecting the increase of these values were proposed. The article also raises issues of variation in demand for mining heritage products and the economic viability of such projects, as well as the recommendations for future investor in the post-mining tourism’ venture were specified.

Comparison of port activities of the East Coast of the Baltic Sea: 1996–2016

The object of research is the performance of ports in the East Coast of the Baltic Sea for the period from 1996 to 2016. By comparing the performance of Russian ports and ports in the Baltic States, the trend of significant growth in cargo turnover in the ports of the region is revealed. The aggregate cargo turnover in the ports of Russia and the Baltic States has increased 4.5-fold over the last 20 years. An analysis of the comparative performance of all the ports of the East Coast of the Baltic Sea for 20 years has shown their growing relevance in development of economic and trade relations between the Asian and European regions. Despite a sharp increase in cargo transshipment in the newly constructed Russian ports (24 times in 20 years), the ports of Latvia, Lithuania and Estonia still show positive dynamics (twice in 20 years). Contrary to the current opinion on the decrease in the role of ports in the Baltic countries, the article shows the factors of their development, including the participation of Russian capital in the construction of new terminals in the ports of Latvia and Estonia (Riga, Sillamae), and by attracting cargo from other regions (Lithuania, Klaipeda). All ports of the East Coast of the Baltic Sea Region have development of potential in expanding ties with the rapidly developing Asian region (China, India). The volumes of transit between Europe and Eurasia are constantly growing, and only in the first quarter of this year the supplies from Europe to China grew by 12 %, and from China to Europe – by 7 %, amounting to 62 billion USD and 81 billion USD respectively. An analysis of the Baltic ports is also important in connection with the development of the large and promising Belarusian project «Great Stone», of which the Chinese national logistics company is a partner and which should connect China via Belarus with the German port of Duisburg. Thus, the possibility of organizing multimodal transportation from Germany to China via the Riga port is being considered because of the limited capacity of the Polish and Slovak railways to transport Chinese goods through the Minsk logistics center «Great Stone» to Europe. In this context, the use of the Riga port with a large potential for development of the port territories can significantly strengthen its economic position, and thereby influence the growth of the Latvian economy. The following factors influence the development of transport corridors in the Baltic Sea Region in order of importance: geography, economics, politics, transport infrastructure and new technologies of logistics business. If we talk about the ports of the Baltic countries, then there is a narrowing of geographical plans due to the reorientation of cargo to Russian ports. The economy is influenced by tariff policy. The influence of politics is still great. The most optimistic is the impact of transport infrastructure.

Finally, this paper improved the energy efficiency of the system. The lowest unit energy consumption could reach 4.54kWh/m3. The results indicate the feasibility of OTE used for desalination and its competitiveness against common solar desalination method.

Influence of TiC nanoparticles on microstructures and properties of electrodeposited Ni–P coatings

Electrodeposited composite coatings show large development potential, thanks to particular properties obtained by the incorporation of particles. In the present work, Ni–P and Ni–P/nano-TiC coatings were electroplated on steel substrates. X-ray diffraction technique, scanning electron microscopy, energy-dispersive analytical X-ray, microhardness, potentiodynamic polarisation and electrochemical impedance spectroscopy were utilised to study the influence of addition TiC nanoparticles and heat treatment on corrosion resistance and physical properties of the applied coatings. The TiC nanoparticles were found to be embedded in the Ni–P alloy matrix and post heat treatment resulted in NixPy phase precipitation which caused the increasing microhardness of deposits. Electrochemical impedance spectroscopy and polarisation tests showed that the addition of nano-TiC particles and proper heat treatment demonstrated significant increase in corrosion resistance of Ni–P coatings in 3.5 wt.% NaCl solution.
