Authors: Andrade Bruno Wilson , Mariani Fábio Edson , Coelho Reginaldo Teixeira , Malafaia Artur Mariano Sousa 
Published: August 2024

Abstract

The microstructure and oxidation resistance at 900 and 1000°C of Additively Manufactured (AM) by Directed Energy Deposition (DED) and Conventionally Manufactured (CM) Inconel 625 alloys were studied. The microstructure of the AM samples was cellular, with Nb and Mo segregations located in the dendritic and interdentritic regions. At 900°C, the oxidation rate was similar for both materials, but was clearly higher for the AM material at 1000°C, being related to the segregation and porosity present in the microstructure of the AM samples. Decrease in porosity by DED changing parameters allowed better oxidation resistance, but still considerably inferior than CM samples at 1000°C. After oxidation, a layer of Cr2O3 was identified under all conditions, providing high resistance to oxidation. Internal oxidation of alumina was also observed in the CM and AM samples. The delta phase Ni3(Nb, Mo) was observed for the CM and AM alloys at the grain boundaries (900°C) and at the metal/oxide interface for both temperatures as a result of chromium depletion. Finally, the oxide layer formed was compact and dense, and some voids were formed in the subsurface region of the samples produced by AM.

Abstract

Exploring the diversity of above and belowground water-use traits among coexisting plant species can improve understanding of soil water partitioning in species-rich plant communities and provide insights into how dryland vegetation copes with drought stress. We assessed the diversity of plant water use strategies among coexisting woody species at 10 Mediterranean ecosystems with contrasting climatic conditions (62 species in total). Soil and stem water isotopic composition (ẟ18O, δ2H) were measured to estimate plant water uptake depth using Bayesian mixing models, while leaf carbon and oxygen isotopes (ẟ13C, Δ18O) and the ratio of leaf area to sapwood area of terminal shoots were used as time-integrative proxies of intrinsic water use efficiency, stomatal conductance, and plant investment in foliage relative to woody stems, respectively. We found that distinct vertical ecohydrological niche segregation, driven by differences in water uptake depth among coexisting species, is widespread and ubiquitous across all sites. Leaf-level stomatal regulation stringency and water use efficiency also differ widely among coexisting woody species and are both coordinated with water uptake depth across species and life forms. Within Mediterranean plant communities, larger woody species use deeper soil water sources and exhibit more conservative, water-saver strategies at leaf level coupled to greater investment in foliage relative to sapwood. In contrast, smaller woody species within the same plant communities rely on shallower soil water sources and exhibit a more profligate, water-spender strategy at leaf-level coupled to lower investment in foliage relative to sapwood. We conclude that drought and heat stress in Mediterranean ecosystems favour tight coupling and coordination between multiple above and belowground water use traits, resulting in possibly unavoidable trade-offs that constrain the diversity of whole-plant water-use strategies that are ecologically and physiologically feasible in native plant communities.

Graphene from Solid Waste Materials for Water Purification
Authors: Waghmode Shobha , Butala Deepali P. 
Published: August 2024

Graphene is both the thinnest and the lightest material studied by the
scientists. Amongst the various applications of graphene, water purification is the
major one. Originally graphene was prepared using graphite and other hydrocarbons as
precursors. Recently waste materials like rice husk, hemp, paper cups, and other
biomass have been used as graphene precursors. Similarly, graphene can be
synthesized from plastic wastes like PET (polyethylene terephthalate) bottles waste as a
source material and polyethylene(PE) and polypropylene(PP) as a carbon source.
Water is required by human beings for living, house chores, and industrial processes.
Waste water treatment is an essential topic related to human health and industrial uses.
Water pollutants are mainly divided into two types; organic water pollutants and
inorganic water pollutants. The organic water pollutants are dyes, pharmaceuticals,
fertilizers, pesticides, herbicides, polycyclic aromatic hydrocarbons, etc. Inorganic
water pollutants are rare earth elements like La, Ce, Ho, Eu, and Y, other organometallic catalysts, and fertilizers containing heavy metals. Waste water treatment
processes are essential to eliminate or decrease pollutants and provide a safe water
supply. Study shows that graphene and graphene oxide are promising materials for
eliminating pollutants from water.

Employment of Specially-Abled People in the Hotel Industry—An Indian perspective
Authors: Singh Amrik 
Published: August 2024

Abstract
A person with a disability implies a personage with a defined impairment of not less than 40% as per the Gazzette of India. Disability is a collective term that covers (1) impairments (a body function or structure problem), (2) limitations on the operation (related to difficulties in performing a task or action), and (3) constraints on participation (an issue found in life circumstances involvement); The International Classification for Functioning (ICF) definition of disability that states “disability is caused by a complex relationship between body structures, functions and impairments, reflecting the circumstances in which a person lives” will be used. Research conducted by the American India Foundation (AIF) identified different career opportunities for specially-abled persons in India, including examples from the hotel and catering industries. The present scenario of specially-abled people in the Indian hotel industry was explored to understand the opportunities and hindrances in the process and how they can be resolved to increase their employment for a dignified life and an inclusive Indian society as a presumed national goal by the NITI Aayog. This study connects the demand for a competent workforce in the Indian hotel sector with the employment needs of specially-abled people.

Authors: Ferreira Ana , Correia Marisol B. , Renda Ana Isabel 
Published: August 2024

Abstract
This systematic literature review analyses included peer-reviewed journals published from 1 January 2008 to 31 May 2022, using 19 keywords related to content shared by tourists and the hotel sector, in the Biblioteca do Conhecimento Online (B-on) and the Web of Science (Wos). The 39 articles considered for this analysis were classified according to the name of the journal in which they appeared and their respective year of publication, the location of the hotels analysed, the booking and opinion platform used, as well as the number of reviews and hotels studied. In addition to contributing to the existing literature on online reviews, this study provides theoretical input that hoteliers can use to aid their business performance and enable the development of further research by scholars. Although several studies analyse online reviews, these are still being little-used in the hotel industry in order to profile tourists. In this respect, this work intends to fill this research gap.

Abstract
Various entities offer to evaluate the adequacy of applications for urban waterfront development. This study focused on the underlying assumptions that gave a comprehensive review of urban waterfront development projects and applications and analysed user impressions in Kyrenia Ancient Harbour. Visitors to Kyrenia, including employees, employers, students, and creative people, were asked to complete a questionnaire. This study discovered that the twelve underlying factors of creative waterfronts included awareness of people, promotion of entrepreneurs, creative spaces and activities, innovation, tolerance, physical comfort, political support, social cohesion, diversity of function, economic contribution, and cultural preservation. An evaluation of the creative environment at Kyrenia Waterfront found various degrees of user participation based on several statistical tests. Most community members saw the example area favourably due to its distinctive urban characteristics and socialisation possibilities. Locals, however, believe that creative folks require new technologies and ideas to be more productive.
Local Identity, Language and Sustainable Tourism: Results of a Survey of Madeira University Tourism Students About their Communities
Authors: Nunes Naidea Nunes 
Published: August 2024

Abstract
This study shows the potential of culture, society, and language tourism for the sustainable development of the island of Madeira. The intention is to ascertain the level of knowledge of students in the higher professional technical course of tourist information and marketing at Madeira University about their local identity and the importance of cultural heritage for sustainable tourism. The research question is about the role of communities‘ tangible and intangible cultural heritage (ICH) (including language or linguistic heritage) for the sustainability of tourism in the region. The qualitative and descriptive methodology used is based on data collected through a questionnaire with open questions applied in the classroom to 43 tourism students from different localities about their cultural heritage and identity. The results of the sample show that religious festivities, Madeiran regionalisms and traditional expressions were registered in Funchal and outside. For the city of Funchal (the capital of Madeira) there are more indications of tangible cultural heritage. For the other municipalities, ICH predominates with diverse local handicrafts and festivities of agricultural products. Thus, communities’ preservation of their ICH is fundamental for local identity and sustainability. Students, together with Madeiran cultural associations and local people, have an important role to play in the authenticity and sociocultural sustainability of regional tourism.
Analysis of Hospitality Sphere Competitiveness in Ukraine on the Basis of Social Dialogue
Authors: Zavarika Halyna , Zelenko Olena 
Published: August 2024

Abstract
This article is devoted to the analysis of the competitiveness of the hospitality sector of Ukraine on the basis of social dialogue during the period of martial law. It is found that the competitiveness of hospitality enterprises differs significantly depending on the location. Also, it is identified that in order to strengthen the competitive advantages of Ukraine in the international market of hospitality services in the post-war period, it would be advisable to base it on the positions that received optimal ratings, namely the price competitiveness of the hospitality industry, the presence of cultural, historical and natural monuments attractive to tourists. At the same time, it is proved that social dialogue can simplify and accelerate the process of interaction at the level of hospitality service providers, which will contribute to a faster increase in the level of competitiveness of the hospitality industry of the affected country. The priority steps of the post-war restoration of the hospitality industry in order to increase its competitiveness are proposed, including the creation of a competitive national tourism product and its promotion to the world market of tourist services. A fundamentally new vision of a change in the scientific paradigm associated with a long-term crisis and military state, which led to the transformation of accents in the problem-subject area, is substantiated. For the first time, the conceptual components of the development paradigm for the Ukrainian hospitality sphere on the basis of sustainability and social dialogue are identified.

Authors: González Rosas Erika Lourdes , García Andrés Carrión , Reynoso Ramón Navarrete 
Published: August 2024

Abstract
The purpose of the research was to know the profile of the attendees of the Guanajuato International Film Festival and to investigate whether there are differences between residents and visitors in terms of their motivations and types of events. The dimensions of production, family unity, exploration, escape, festival attractiveness, and experience were used for motivation. Attendance by event genre and sociodemographic variables (age, gender, residence, etc.) were also examined. The study consisted of administering 362 questionnaires to those attending festival events. This information was analysed to look for differences between strata using Student’s t-test and Mann-Whitney tests. The results show that there were no significant differences between residents and non-residents, except in the festival attractiveness dimension which was higher for outsiders. Differences were found in visitors who attend some genres of events in terms of their behaviour as tourists. The uniformity of behaviour between residents and visitors confirms the importance of attendance, cohesion, and inclusion of the community that hosts the events and has a positive effect. The limitation of the study is the sample size. Additional research should address the analysis and evaluation of the costs and benefits of the festival.
Searching for Life Satisfaction in Nature through Tourism: An Exploratory Research on Hikers
Authors: Karacaoğlu Sıla 
Published: August 2024

Abstract
Hiking is a walking activity carried out in predetermined natural environments. It is practised by many people because it does not require much equipment and expertise, and it also offers its participants a much more economical leisure time activity than other sports branches, besides providing positive impacts on health and well-being. In this respect, the study investigated whether there is a relationship between hikers’ perceptions of nature, the benefits they get from hiking, and whether there is a relationship between hiking and life satisfaction. A qualitative approach was adopted, and a semi-structured interview form was prepared by utilising the relevant literature. In this context, interviews were conducted on 24.04.2023–11.06.2023 with 21 hikers over the age of 18 who were hiking in nature groups in Eskişehir with purposive and snowball sampling methods. The answers obtained were subjected to descriptive analysis. The results revealed that almost all the participants started hiking with intrinsic rather than extrinsic motivations. The findings also show that hiking has an important place in the lives of individuals, that it positively affects the lives of the participants, and that its non-economic benefits make significant contributions to increasing the life satisfaction of the participants.
The Disputes Around The Construction of A Regulatory Framework in The Communications Sector in Brazil: An Analysis Based on The Advocacy Coalition Framework
Authors: Darbilly Leonardo Vasconcelos Cavalier , Prata Leticia Cardoso 
Published: August 2024

Objective: the objective of this research work is to analyze how conflicts occur around the construction of a regulatory framework for the communications sector in Brazil

Theoretical Framework: The Advocacy Coalition Framework (ACF) approach is used, initially developed by Sabatier and Jenkins-Smith (1993). Also, a characterization of the communication sector in Brazil is carried out.

Method: The research is qualitative in nature and data was collected through semi-structured interviews with representatives of some movements that fight for the democratization of the media in Brazil

Results and Discussion: The analysis of primary and secondary data indicated that the elements perceived by the interviewees as being those that most contributed to the emergence of coalitions in favor of the democratization of the media in Brazil were predominantly political and technological. Furthermore, there is an intense conflict between groups that fight for the democratization of the media and those that are against any initiative in this regard.

Research Implications: It is intended, through the results achieved, to bring elements that help guide the various debates carried out by civil society with the aim of discussing the democratization of the media in the country.

Originality/Value: Discussions about the field of communication in Brazil from a perspective that focuses on power struggles between different groups in society are uncommon in management literature, especially based on the use of the defense coalition model .
