Abstract
Purpose
The purpose of this paper was to assess the knowledge on sport and exercise science held by a sample of Brazilian physiotherapists, nutritionists and physical educators.
Design/methodology/approach
A cross-sectional research design was used. The answers given by 1,147 professionals (300 physiotherapists, 705 physical educators and 142 nutritionists) who participated in a qualifying process for a specialization course on exercise physiology were analyzed. Questions were analyzed on maximal oxygen uptake (four questions), physical fitness assessment (three questions), physical training (two questions), bioenergetics (one question) and exercise in extreme environments (one question).
Findings
The results revealed misconceptions held by Brazilian health professionals on a number of concepts related to sport and exercise science, such as maximal oxygen uptake.
Practical implications
These results reinforce the need for continuing education programs to maximize the quality of the service provided by sport and exercise science professionals in Brazil. Improvements in the undergraduate courses curriculum are also recommended.
Originality/value
This is the first study to assess misconceptions about sport and exercise science among Brazilian health professionals.

This paper aims to present the results of a post‐occupancy evaluation (POE) in a complex hospital building, and also to discuss a system for analyzing and diagnosing those results.
Abstract
Purpose
This paper aims to present the results of a post‐occupancy evaluation (POE) in a complex hospital building, and also to discuss a system for analyzing and diagnosing those results.
Design/methodology/approach
The POE was aimed at establishing adequate use and maintenance of the building. The main approaches of the study consisted of two basic performance features, namely, physical accessibility and fire safety.
Findings
The importance of the pre‐design evaluation (PDE) might also be recalled as well as the usefulness of the POE for new designs and for remodeling existing buildings, because these instruments aid in the constant updating of directive plans of occupation, especially in the case of large complexes such as health care facilities. One indication of this importance is the relatively low number of problems detected during the POE, when one considers the complexity of the work of renovation and the dimensions of the IPq facilities.
Originality/value
The paper presents the results of a POE and recommendations that would make it possible to quickly identify the points where there is need for improvement, and the degree of importance or priority to be given.

Abstract
The international tourism options have been enriched due to several factors: new transport technology, more flexible legislation, the globalization process, and political openness regarding some areas dominated by dictatorship regimes. Antarctica is one of the new possibilities for adventure and ecological travel. It is the wildest, most well‐preserved and most isolated continent on the planet. About 10,000 tourists can appreciate its dazzling landscapes each austral summer and tourism operations have increased considerably in the region during the 1990s. This article presents a history of travel to Antarctica, an analysis of the tour operators and of the Antarctic Treaty on tourism, and reports an experience on board one of the cruise ships in the Antarctica Peninsula.

Abstract
Purpose
This paper aims to bring together information on whether any evidence exists of a commercial conflict between the creation of digital archives at research institutions and by key subject centres of excellence, and the business of journal publishing.
Design/methodology/approach
Relevant publications, including articles published in refereed books and journals, as well as informal commentaries on listservs, blogs and wikis, were analysed to determine whether there is any evidence of a commercial relationship.
Findings
Most of the published comments are highly subjective and anecdotal – there is a significant emotional overtone to many of the views expressed. There is precious little hard evidence currently available to support or debunk the idea that a commercial conflict exists between repositories and journal subscriptions. The situation is made more difficult by the many technological, sociological and administrative changes that are taking place in parallel to the establishment of repositories.
Practical implications
Separating the key drivers and their impact is a major strategic challenge facing all stakeholders in the scholarly communication industry in future.
Research limitations/implications
This is an important area which requires close monitoring – the possible threat that the established journal publishing system could be eroded away by a new “free” scholarly information system needs attention. One significant study in this area is being undertaken by the PEER group, funded by the European Commission with hard evidence being collected by UCL's CIBER research group. The results from this impartial investigation will be very welcome.
Originality/value
The paper shows that relationship between repositories and journal subscriptions is vague.

This study aims to identify the impact of restaurant pandemic mitigation measures on perceived service quality.
Abstract
Purpose
This study aims to identify the impact of restaurant pandemic mitigation measures on perceived service quality.
Design/methodology/approach
A total of 15,251 reviews were collected from 300 TripAdvisor Lisbon restaurant Web pages between March 2020 and December 2021, when Covid-19 contingency measures were in place. Grounded on the online reviews, a word frequency matrix was created and used as input on partial least squares–structural equation modeling to test the proposed hypotheses.
Findings
The results suggest that precaution measures, such as the Vaccination Certificate, negative tests and restaurant layout configuration, positively influenced perceived service quality and consumer satisfaction, moderated by consumers’ beliefs.
Originality/value
This study provides relevant information for restaurant managers, which will help them implement strategies to guarantee service quality, consumer satisfaction and revisit intentions in future pandemic scenarios.

Abstract
Purpose
The purpose of this paper is to study the corrosion of the coupling of two different types of stainless steel, austenitic and ferritic, used in the fabrication of water reservoirs in the solar energy industry.
Design/methodology/approach
Potentiodynamic polarization and gravimetric immersion tests were used to evaluate corrosion of the coupling of two different types of stainless steel, austenitic and ferritic.
Findings
The galvanic corrosion was not significant in the case of the coupling of AISI 304 and 444 steels. The difference of the open circuit potentials obtained for the AISI 304 and AISI 444 steels was 28 mV for the polished samples. The galvanic current density (ig) was 55 nA/cm2. The corrosion observed in the stainless steel couple was in the weld area.
Research limitations/implications
The methodology used is adequate to evaluate generalized galvanic corrosion. The problem of the corrosion in the coupling of the stainless steels is a problem of localized corrosion and the observed 28 mV potential difference was lower than the dispersion of results usually obtained from readings of corrosion potentials in electrochemical cells.
Practical implications
The use of two different types of steel in contact with each other may lead to galvanic corrosion, and the welding of steel pieces may lead to several corrosion problems. Since the boiler may be used in different countries, subject to a great diversity of water quality, corrosion may be a significant problem.
Originality/value
Literature data of the AISI 444 steel corrosion behaviour are still scarce. The coupling of two different stainless steels (AISI 304 and 444) in the water reservoir manufacturing was a necessary requirement of the solar energy industry. The manufacturers of boilers must evaluate and quantify the corrosion processes, which occur in the equipment used in the solar energy industry. As the solar energy industry has matured in the last ten years, the corrosion of this equipment may be a significant problem in due course.

Abstract
Purpose
The purpose of this paper is to forecast wind power generation in an area through different methods, and then, recommend the most suitable one using some performance criteria.
Design/methodology/approach
The Box–Jenkins modeling and the Neural network modeling approaches are applied to perform forecasting for the last 12 months.
Findings
The results indicated that among the tested artificial neural network (ANN) model and its improved model, artificial neural network-genetic algorithm (ANN-GA) with RMSE of 0.4213 and R2 of 0.9212 gains the best performance in prediction of wind power generation values. Finally, a comparison between ANN-GA and ARIMA method confirmed a far superior power generation prediction performance for ARIMA with RMSE of 0.3443 and R2 of 0.9480.
Originality/value
Performance of the ARIMA method is evaluated in comparison to several types of ANN models including ANN, and its improved model using GA as ANN-GA and particle swarm optimization (PSO) as ANN-PSO.

Abstract
Purpose
Due to the increasing population and prosperity, the generation rate of municipal solid waste (MSW) has increased significantly, resulting in serious problems on public health and the environment. Every single person in the world is affected by the municipal solid waste management (MSWM) issue. MSWM is reaching a critical level in almost all areas of the world and seeking the development of MSW strategies for a sustainable environment. This paper aims to present the existing global status of MSW generation, composition, management and related problems.
Design/methodology/approach
A total of 59 developed and developing countries have been grouped based on their gross national income to compare the status of various MSWM technologies among them. A total of 19 selection criteria have been discussed to select appropriate MSWM technology(s) for a city/town, which affects their applicability, operational suitability and performance. All risks and challenges arising during the life cycle of the waste to energy (WtE) project have also been discussed. This paper also gives a comparative overview of different globally accepted MSWM technologies and the present market growth of all WtE technologies.
Findings
It was found that most developed countries have effectively implemented the solid waste management (SWM) hierarchy and are now focusing heavily on reducing, reusing and recycling of MSW. On the other hand, SWM has become very serious in low-income and low-middle-income countries because most of the MSW openly dumps and most countries are dependent on inadequate waste infrastructure and the informal sector. There are also some other major challenges related to effective waste policies, availability of funds, appropriate technology selection and adequacy of trained people. This study clears the picture of MSW generation, composition, management strategies and policies at the worldwide context. This manuscript could be valuable for all nations around the world where effective MSWM has not yet been implemented.
Originality/value
This study clears the picture of solid waste generation, composition, management strategies and policies at the worldwide context. This manuscript could be valuable for all nations around the world where effective MSWM has not yet been implemented. In this study, no data was generated. All supporting data were obtained from previously published papers in journals, the outcomes of the international conferences and published reports by government organizations.
