OUR SCHOOL IN EYES OF GAMER GENERATION: HOW VIDEO GAMES EXPOSE DEEP PROBLEMS OF OUR EDUCATION
Authors: Jovanović Milan
Published: March 2021

From the theoretical perspective of the contemporary educational theory and didactics, there are many problems concerning our elementary and high school curriculums (within the educational system of Republic of Serbia). There is also empirical evidence that our education is outdated, ill-construed and with the problematic conception of the learning process in its core. However, those problems are rarely considered and presented from the students’ point of view. In this paper, I am approaching the problems of our educational system from that perspective. I argue that the deep flaws in our education are even more evident to the newest, so-called: gamer generation. As the argument in favour of this negative claim, I offer an analysis of the learning process within the video games insisting that it is – as a sort of Dewian conception of learning – superior to the learning process typically assumed in our school. On the basis of that analysis, I propose that students acquainted and familiar with such learning process would naturally be even more reluctant and less motivated for learning in old fashioned way still present in our school system. As for the closing and positive part of the paper, my main suggestion is that focusing school curriculums around the competences tightly connected to reasoning and discovering (and also encouraging a heuristic approach as the preferable teaching method) can make our education better in both respects: objectively and in the eyes of the students we teach.
MRGUDA BY PETAR KOČIĆ – A VICTIM OR A REAL HERO
Authors: Denić Sunčica
Published: March 2021

A strong love and suffering because of it, almost an archetypal motif and a common mythopoetic theme, is the basis of the story Mrguda by Petar Kočić. Mrguda represents poeticized death with the power of great ancient heroes of post-Homeric age. It seems that only by death is Mrguda able to restrain body strength and desire, the fire that cannot be quenched; to overpower physical by spiritual. The character of Mrguda can be seen not in the fight, as Vitomir Vuletić wrote, but in yearning for death – or phraseologically – in heroic death. Does a suicide possess heroic or brave qualities, that is an eternal question. Mrguda’s taking is, in one hand, taking of the body, while the soul remains to live; taking the soul would go into another direction – the body does not belong to the universe, memory and eternity anyway.
MODERN APPROACHES TO TEACHING SIGHT SINGING AND EAR TRAINING
Authors: Schüler Nico
Published: March 2021

Sight singing and ear training are difficult subjects to teach. Over the past decade, however, many new technological tools were developed that support educational endeavors. Several of those tools, SmartMusic, SingSnap, EarTrainer (MusicDictation.app), and YouTube, were used at the beginning college-level aural skills courses to enhance sight singing and ear training instruction, especially in the context of enhancing audiation skills. This article summarizes their use within aural skills courses and present experimental and anecdotal evidence of increased sight singing and ear training skills. More specifically, experimental (test) data as well as anecdotal (essay) evidence showed that (1) students were much higher motivated to complete exercises compared to ‘traditional’ aural skills exercises, (2) in a shorter period of time, students performed much better than in ‘traditional’ exercises of at least the same difficulty, (3) the students’ audiation abilities increased much more as a result of the exercises, compared to ‘traditional’ exercises, and (4) students showed a greater increase in solfege proficiency, compared to ‘traditional’ exercises. The teaching approaches we have discussed also led to a greater independence from in-person instruction.
SELFIES, PERFORMATIVITY, AND INDIVIDUALISM
Authors: Stojanovic Prelevic Ivana
Published: March 2021

The paper analyses the influence of selfies on public performance. Contemporary media public is called by some theorists (Rojek, 2015) the “egocentric public”, primarily the users of social networks. Hedonism, consumption and egoism are only some of the characteristics of the modern society, which also points to the characteristics of visual culture. From a philosophical viewpoint as one of the phenomena of visual culture to which special attention is given starting with psychologists, art theorists and communication agents, and all the way to philosophers, the selfie supports the hypothesis that individualism  is characteristic to contemporary culture.The paper examines the performance strength of the selfie (Senft, Baym, 2015) as well as the characteristics of the modern media public. The methods include the analytical and descriptive methods. The conclusion is that the selfie confirms that contemporary culture is dominated by individualism and that, from a pragmatic point of view, the contemporary media public belongs to the “culture of selfies“ in which the subject simultaneously becomes an object emphasizing  narcissism and the illusionary focus on the other.

Authors: Stanković Aleksandar , Marković Danijel , Petrović Goran , Čojbašić Žarko
Published: March 2021

This paper presents a methodology for solving the municipal waste collection problem in urban areas. The problem is treated as a distance-constrained capacitated vehicle routing problem for municipal waste collection (DCCVRP-MWC). To solve this problem, four meta-heuristic algorithms were used: Genetic algorithm (GA), Simulated annealing (SA), Particle swarm optimization (PSO) and Ant colony optimization (ACO). Vehicle guidance plays a huge role in large transportation companies, and with this test, we propose one of several algorithms for solving urban waste collection problems.
TOP-DOWN AND BOTTOM-UP POLICY IMPLEMENTATION APPROACH – THE CASE OF WIND POWER DEVELOPMENT IN THE NORDIC COUNTRIES AND THE REPUBLIC OF SERBIA
Authors: Vučić Vlastimir , Radović Vučić Miljana
Published: March 2021

Environmental policy integration (EPI) is the incorporation of environmental concerns in sectoral policies outside the conventional environmental policy domain. Dealing with such concerns is necessary because research indicated that the institutional specialization of policies for specific sectors has resulted in insufficient consideration of environmental impacts, as sectoral policies might have objectives in conflict with environmental objectives and are able to influence the root causes of environmental pressure. There is a consensus that the link between environment and energy policies has transformed and modified the energy policy in Europe, not the least by the potential of renewable electricity (RES-E). Therefore, studying the RES-E perspective within an EPI initiative is relevant and the present article aims to contribute to a more sector-specific understanding of EPI. More precisely, by focusing on the conditions for the expansion of wind energy in the Nordic countries and Serbia, the present research aims to illustrate the necessity of understanding the national, regional and local contexts for more effective RES-E implementation.
DYNAMIC CHARACTERISTICS OF THE WALL STRUCTURE DURING THE HEAT TRANSFER PROCESS
Authors: Kalinović Saša , Đoković Jelena , Tanikić Dejan
Published: March 2021

This paper deals with the impact of high-density thermal mass materials of the wall structure on the dynamic characteristics of a multi-layered building envelope during the heat transfer process. Since the final objective is to design the most energy-efficient building, i.e. a building with the lowest heating and cooling energy consumption, it is necessary to achieve good thermal performances of a multi-layered wall. In order to find the optimal wall structure solution with the highest energy-saving potential, different wall structures with different layer thicknesses were analyzed, along with walls of the same structure with different positions of individual thermo insulating layers within the wall. Based on the results presented in this paper, it can be concluded that at walls with similar structures and the same total thickness, but different layer thicknesses that make up the complete structure of the wall, there are differences in delaying external temperature changes on the wall. However, the position of the thermal insulation layer does not significantly affect temperature oscillation amplitude caused by external temperature change.
HEAVY METALS IN THE SOIL OF POTENTIAL TOBACCO PRODUCTION LOCATIONS IN VRANJE VALLEY
Authors: Golubović Tatjana , Arsić Milica , Arsić Srđan
Published: March 2021

Before the change of the ownership of the Vranje Tobacco Industry, there had been a large scale tobacco production in the valley of Vranje. The number of tobacco growing households has declined significantly over the last 15 years, despite the good potential of agricultural land for growing this crop. Given the fact that the quality of tobacco depends on the conditions under which it is grown, above all on the soil quality, it is very important to be familiar with the soil composition and the presence of potential pollutants in soil, as well as the mechanisms of their transmission to the plant. Pollutants in agricultural land originate from natural and anthropogenic sources. Significant anthropogenic sources of soil pollutants are agricultural production (organic fertilizers, pesticides, etc.) and road transport. When it comes to tobacco quality, one of the most important groups of pollutants is heavy metals. Mineral and organic fertilizers, as well as pesticides often contain heavy metals. Considering the above facts, the aim of this paper was to determine and analyze the concentration of heavy metals such as Pb, Cd, Cr, Cu, Mn, Zn and Ni in the soil of the villages Neradovac, Ćukovac and Surdul, which are considered as potential sites for tobacco production. The surveys covered two periods, 2005 and 2018 (the analysis of soil) and 2005 (the analysis of tobacco). A comparative analysis of the results showed that the concentrations of heavy metals at the examined locations in soil and tobacco sampled in 2005, as well as the concentrations of heavy metals in soil sampled in 2018, were below the maximum allowable and remediation values. Because the remediation values of pollutants and hazardous substances in the soil are the values, which, if exceeded degrade the level of safety, it can be concluded that these values were not exceeded in either of the analyzed samples and that the soils were potentially safe to use with the additional tests and the necessary limitations in operating mode. Also, the chemical composition of the soil in these areas indicated that the values of the tested parameters were within the optimal values for the growth and development of plants without a negative impact, which again confirms the assumption that these localities are suitable for tobacco production.

Published: March 2021

In this paper, the analysis of SO2 concentrations in the Bor town (Serbia) is presented for the period 2011-2020. The results of measurements from the period of operation of the old copper smelter (2011-2015) were compared with the results of measurements during the period of operation of the new copper smelter (2016-2020). As a result of changes in the copper smelting technology and the better treatment of waste gases in the smelter, on average, the level of SO2 was reduced by 67% in the period 2016-2020 compared with the SO2 level in the period 2011-2015. The presence of a weak (r<0.4) Pearson correlation between the SO2 levels among the sampling points were determined in both periods of observation.
INSURANCE AS A PREREQUISITE FOR RISK MANAGEMENT IN WORKING AND LIVING ENVIRONMENT
Authors: Živković Snežana , Ilić Petković Aleksandra
Published: March 2021

Insurance is an economic and service activity that protects people and their property from the consequences of numerous hazards. Therefore, insurance companies face the risk of financial loss. Improperinsurance premiums caused by an inadequate risk assessment that is assumed in insurance are the most common cause of such losses. In order to minimize the possibility of unwanted losses, it is necessary to carry out adequate business management processes in insurance. In doing so, special attention should be paid to the risk assessment process. A quality risk assessment is of the utmost importance for the functioning of the overall insurance system. Insurance itself can play a significant role in managing the risks in working and living environment whereas the legal regulation gives security to the insurance entities.
CFD ANALYSIS OF TEMPERATURE FIELD IN PELLET STOVE AS A GENERATOR OF AN ABSORPTION HEAT PUMP
Authors: Ilic Marko , Stefanović Velimir , Pavlović Saša , Ilić Gradimir
Published: March 2021

The paper presents an initial CFD study on adopting the biomass-pellet usage in a generator of an absorption heat pump by obtaining the temperature field inside the biomass furnace. Contemporary absorption technologies are mostly based on the use of gas and other waste heat as a driving force in the Generator, where the two-component working fluid splits into the refrigerant and the absorbent. There are few or no absorption heat pumps that work directly on biomass - pellets. In the Balkans, biomass - pellets are a frequent and renewable source of thermal energy. The aim of this paper is to initially research the possibility of an absorption generator to work directly on available pellets. Following this idea, a comprehensive overview of contemporary absorption technology is given with a physical and mathematical model of the small pellet stove in FLUENT, which will be modified to adapt the generator. In the beginning, temperature fields are obtained by simulation inside the furnace and on its surfaces. Work showed that the temperature field has enough potential for triggering the absorption process as temperatures in the upper part of the stove are above 400°C at the heating capacity of around 13 kW up to 20 kW. The implemented work and the obtained results could serve as a useful reference for further design and optimization of the generator of AHP for direct Biomass utilization for a middle size system.
THE RELATION OF OCCUPATIONAL SAFETY MOTIVATION AND AGE, YEARS OF SERVICE AND PROFESSIONAL QUALIFICATIONS OF EMPLOYEES
Authors: Rakić Tomislav , Živković Snežana
Published: March 2021

Autonomous occupational safety motivation can be a result of outer and inner reasons for applying safety measures at work. Employees with autonomous motivation behave apply safety measures at their own insticts and initiative, in line with their values and interests. As a result, the behavior of autonomously motivated employees is self-determined and therefore, it should be applied consistently.Along with this kind of motivation, an “identified” workplace  safety motivation is worth mentioning. It is typical for employees who are motivated to apply occupational safety measures because they consider that safe work environment is very important, and that acting in accordance with safety measures is just another step towards safe work environment.The main aim of this paper is to establish potential relations between occupational safety motivation on one side, and age of the examinees, the years of service, and their professional qualifications on the other, in order to implement the results obtained, create safe work environment and, in this way,  increase the productivity.

The experiment took place in the educational context of vocational training at a post-compulsory state vocational school in the region of Valencia, Spain. The learners who participated in this experiment were studyingthe first year of Vocational Training Administration and Business Management during the academic year 2018-2019. The sample was formed by 23 learners who, aged between 25 and 45, participated only in the treatment group. The research questions explore how blogging can be utilized to help learners improve their ESP written production within the Cooperative Learning Approach. The action research model is employed to analyze the quantitative outcomes from this experiment.
NEONYM ANALYSIS IN THE ENGLISH LANGUAGE FOR TOURISM PURPOSES
Authors: Orel Frank Tina
Published: March 2021

Languages are subject to constant change, with new lexis being just one, yet the most sensitive. Languages for specific purposes are no exception, and this is particularly true in areas that are currently undergoing rapid development, such as tourism. The aim of the research is to analyze neonyms in the English tourism language from the perspective of new lexicon-building processes. Neonyms are understood as terms in the neologistic phase of the lexical life cycle. The contribution extracts them according to their subjective time-bound definition in the field of tourism based on the use of Internet sources as corpus, which is particularly suitable for the research of new language. The paper contributes to the understanding of tourism as a field and its specific language and sheds light on recent (often unsystematic) term formation processes. It shows indirect theoretical word formation tendencies, which are also applicable when comparing word formation processes in General English as opposed to the English language for tourism purposes.
MODELLING ESP TEACHER IDENTITY IN UKRAINIAN TERTIARY EDUCATION
Authors: Rebenko Maryna
Published: March 2021

In an attempt to leverage knowledge in an ESP classroom, some university teachers find not much support from the university staff and administration in Ukraine. Yet, it hardly restrains ESP teachers to eagerly develop and construe their professional identity aimed at equipping students with employability literacy skills. A two-stage survey of three different groups of respondents was conducted at Taras Shevchenko University of Kyiv, Ukraine. The findings on the open-ended questionnaire allowed designing a rank of identity constituents, which appeared to be different in research groups’ perceptions. While both language and subject teachers valued “individual features” as the most significant and “work experience” as the least, the students correspondingly ranked the other categories – “professional knowledge” and “foreign language competence”. Within the close-ended questionnaire dataset, these discrepancies vanished. All research groups agreed on the model of “ideal” ESP teacher identity as a combination of significantly ranking categories: “methods of teaching” → “professional knowledge” → “individual features” → “foreign language competence” → “work experience”. The “professional knowledge” category was estimated twice as significant as the “work experience” domain. The research results are consistent with the recent studies on teacher identity simulation. New was ranking the ESP teacher identity model on constituents’ significance based on opinions of three different social groups – students, language teachers, and subject teachers. The worked-out model could remedy ESP teacher identity ambiguity due to approach fruitfulness.

Authors: Liashenko Iryna , Hnapovska Lyudmyla
Published: March 2021

Along with providing plentiful job market opportunities, the ongoing growth of various technologies in a wide range of fields is currently creating a high level of graduates competitiveness. The issue of employability, which is the crucial concern of higher education institutions, is getting vital these days among employers, educators, researchers, and future professionals. This study aims to determine the mechanisms through which an ESP distance course can facilitate employability enhancement with graduate students. Although the idea of implementing distance learning in the professional training is not new, coherent research on how to make online tasks more enriching for future professional activity and thus resulting in enhanced employability has not been proposed so far. A survey conducted within the framework of the study reveals a correlation between critical thinking skills tasks as part of an ESP course and growing professional competence as an integrated component of employability. The data obtained have been verified by statistical analysis. Another investment in the employability field has been made through suggestions on how to design online tasks properly.

Authors: Meristo Merilyn , López Arias Francisco Javier
Published: March 2021

Due to the growing importance of globalization, the English language has acquired an even more influential role, and at the tertiary educational level it has provoked the necessity of teaching not just general English, but also English for Specific Purposes (ESP), which meets the demands of students' field of study. Moreover, the preparation of undergraduate students for both entering the labour market or continuing their academic path has prioritized the significance of ESP. This paper aims to investigate how ESP teachers working in Estonian state-funded HEI with General English teaching background perceive their work in the field of ESP. Specifically, this abductive qualitative research seeks to obtain a deeper insight into the challenges posed by teaching ESP and to detect problematic issues to better support university teachers to improve their work. The results highlight three major challenges: coping with changes through the lenses of professionalism; insufficient collaboration, and instability in conducting ESP courses.

Authors: Carrasco-Flores José Andrés , Alcaraz-Mármol Gema
Published: March 2021

The present study explores the communicative potential of two ESP textbooks. It examines a sample of activities of English for Commerce and  English for Medicine textbooks with an instrument of analysis consisting of three parts: (1) a section for the metadata of the activities, (2) a checklist which assesses the presence and distribution of language skills and systems, and (3) a scale devised by Criado (2016) which measures the weight of meaning-focused and form-focused instruction found in activities. To study these elements, a framework describing and illustrating each component was designed. Inter-rater reliability tests were carried out to ensure the validity of the results. The findings of the study suggest that these textbooks are mainly meaning-focused, although some differences as regards the extent to which each of these elements is promoted can be found. Moreover, several methodological issues are raised in order to improve future research concerning materials analysis.

Authors: Nikolayeva Larysa
Published: March 2021

Current research explores the response of Arab undergraduate Business students to text adaptation. The data was collected in Majan University College, Oman, during the academic year 2018 - 2019. Incorporated at the time of developing learning aids, students’ response can serve as one of the tools for enhancing students’ language skills required for their academic success. The analysis is based on the response of two mixed-gender groups of students (23 and 31 students respectively) obtained through a micro test and a text difficulty survey addressing their comprehension skills of authentic versus adapted texts. The effect of the text and sentence length, grammatical complexity, and academic vocabulary on students’ comprehension were considered in the study. The research demonstrates the need for amending the text for Arab students, identifies the areas of concern and helps material designers working in the Arab world to choose the most linguistically and culturally appropriate approaches to text manipulation.
LITERATURE AS A TOOL OF AWARENESS: TRAITS OF AUTISM SPECTRUM DISORDERS FOR STUDENTS IN ESP CLASS
Authors: Židová Diana
Published: March 2021

The prevalence of Autism Spectrum Disorders (ASDs) in children is increasing from year to year worldwide. People suffering from this disease experience the feelings of otherness and isolation, even social exclusion. To raise awareness to this problem, every year a World Autism Awareness Day is celebrated on April 2. This paper will focus on the personality pervasiveness of ASD as depicted in the widely acclaimed novel “The Curious Incident of the Dog in the Night-Time” (2003) by Mark Haddon. The book, a detective story, which centers around the adventures of a teenage boy who suffers from many behavioral traits typical of ASD, can serve as a tool for teaching ASD behavior to the future experts in pedagogy and special needs assistants, who provide professional advice. It also provides a comprehensive lesson plan in ESP class with several tasks which build upon the means of critical thinking on the topic.

Pathological gaming in South Korean adolescents from the perspectives of self-esteem and self-control
Authors: Jeong Eui Jun , Lee Daeyoung , Lee Sung Je , Kong Jeonyoung
Published: March 2021

We empirically tested how environmental factors (i.e., parents, peers, and teachers) around South Korean adolescents affect the psychological factors (i.e., self-esteem and self-control) related to self-identify formation, and how each of these factors ultimately affects pathological
gaming. Using a three-wave (6-month interval per wave) panel survey design, we conducted a survey with 1,037 adolescents in South Korea and verified the relationships using structural equation modeling. The results indicate that adolescents with higher self-control and selfesteem showed low
levels of pathological gaming. Self-control (vs. gaming time) had a stronger effect on pathological gaming, and school environment (vs. gaming time) had a greater effect on self-control. Selfesteem, mostly influenced by parental environment, diminished pathological gaming. Our results show
the critical role of these psychological factors in preventing adolescents' pathological gaming, regardless of gaming time.
Influence of spatial configuration in coworking spaces on entrepreneurial bricolage: Evidence from China
Authors: Han Ying
Published: March 2021

In this study the emerging phenomenon of coworking is contextualized within a theoretical framework. I conducted a survey with 310 people in China who were working in coworking spaces. Using multiple regression analyses, I assessed whether physical design, social networks, and individual
trust (i.e., spatial configuration) in these shared environments stimulates entrepreneurial bricolage. The results show that physical design positively influenced entrepreneurial bricolage in the coworking space; that network ties had a mediating effect, which confirms that social networks
partially mediated the relationship between physical design and entrepreneurial bricolage; and that individual trust moderated this mediating effect. This study provides new insights into the mechanism of entrepreneurial bricolage in coworking spaces from the perspective of spatial configuration.
The study findings have major implications for research into improving management of coworking spaces because the focus was on spatial configuration and the effect of this in decision making for entrepreneurial bricolage.
Effect of aging on visual attention: Evidence from the Attention Network Test
Authors: Fu Jia , Yu Guoming , Zhao Lun
Published: March 2021

We investigated the effects of aging on attentional functions using the Attention Network Test (ANT), which enables simultaneous testing of alerting, orienting, and executive networks, and their interactions. Participants were 38 young adults (Mage = 21.35 years) and
36 older adults (Mage = 71.17 years). Although the older adults exhibited a slower overall response, the three attentional functions showed different modulation according to age group and the trial block being completed. Older adults exhibited significant impairment in the
alerting function, regardless of whether they were completing the first or second block of trials, whereas their executive function decreased significantly only in Block 2 owing to cognitive fatigue. Both age groups performed similarly for the orienting function. Future researchers should
seek to further clarify the specificity of attention function with people aged over 70 years to address their attention disturbance.
Comparison of attentional resource allocation to threat and selfrelevant information: An event-related potentials study
Authors: Wang Guan , Liu Yuting , Fang Yuan
Published: March 2021

Although previous researchers have shown that attention is preferentially allocated during situations involving both threat and selfrelevant information, it is unclear which information type requires more cognitive resources. We compared the automatic processing of threat and self-relevant
stimuli using the no-report oddball paradigm. Participants looked at images on a computer screen that displayed fighting with opponents or interacting with friends or customers. The body action of the person depicted was performed either toward the viewing participant or toward other people.
Participants watched without making an explicit response, and event-related potentials were measured with electroencephalography. We found that threat (vs. selfrelevant) information elicited a larger P300 amplitude, and for nonthreatening events the P300 amplitude was larger for self-relevant
than other-relevant stimuli. These results indicate that threat (vs. selfrelevant) information demands more cognitive resources, possibly because people prioritize survival.
Impaired In-vitro Platelet Aggregation and Secretion Tests in Children with Henoch-schöenlein Purpura
Authors: Yazarlı Esra , Ağras Pınar Işık , Dallar Yildiz , Alioglu Bulent
Published: March 2021

Abstract Aim: This study aimed to investigate the in-vitro platelet
aggregation and secretion tests in children patients with
Henoch-schöenlein Purpura that recently referred to as Ig A vasculitis
Methods: This is a cross-section study that included 55 patients with
Henoch-schöenlein Purpura and 31 healthy children as a control group.
Children who have a history of drug use, chronic diseases, and bleeding
diseases were excluded from the study. Complete blood count, thrombocyte
aggregation, and secretion tests were studied in both groups. These
tests were re-evaluated in remission of the disease. Results: It was
found that epinephrine-stimulated platelet aggregation and collagen,
epinephrine, ristocetin, arachidonic acid, standard dose thrombin, and
high dose thrombin-stimulated platelet secretion results were lower in
the patients with Henoch-schöenlein Purpura compared to the healthy
control group in the acute period (respectively P=0.014, 0,003; 0,003;
0,027; 0,034; 0,010; 0,049). When the values of patients with
Henoch-schöenlein Purpura in the acute period and the remission of the
disease were compared, collagen-stimulated platelet aggregation and
epinephrine-stimulated platelet secretion values were found to be lower
in patients with patients in the acute period (P= 0.016; 0.039)
Conclusion: Impairment in vitro platelet aggregation and secretion tests
in the patients with Henoch-schöenlein Purpura suggest that the tendency
to bleeding in these patients may be due to platelet impairment
function. Key Words: Henoch-schöenlein Purpura, platelet aggregation
tests, platelet secretion tests, children, Ig A vasculitis. What’s
already known about this topic? There is a tendency to bleeding in
Henoch Shcöenlein Purpura patients, such as gastrointestinal bleeding,
nonthrombocytopenic system purpura. What does this article add? It was
found that impairment in-vitro platelet aggregation and secretion tests
in Henoch Shcöenlein Purpura patients.

Abstract Introduction: Linear ablation in addition to pulmonary vein
antrum isolation (PVAI) has failed to improve the success rate for
persistent atrial fibrillation (PeAF), due to incomplete block of
ablation lines, especially in the mitral isthmus (MI). Methods and
results: The study enrolled 191 patients (66 in group 1 and 125 in group
2). In group 1, EI-VOM was firstly performed, followed by radiofrequency
(RF) applications targeting bilateral PVAI and bidirectional block in
the roofline, cavotricuspid isthmus, and MI. In group 2, PVAI and the
three linear ablations were completed using only RF energy. MI block was
achieved in 63(95.5%) and 101(80.8%) patients in group 1 and 2,
respectively (p=0.006). Patients in group 1 had shorter ablation time
for left pulmonary vein antrum (8.15 min vs 12.59 min,
p<0.001) and MI (7.0 min vs 11.8 min, p<0.001) and
required less cardioversion (50(78.5%) vs 113(90.4%), p=0.007). During
the 12-month follow-up, 58 (87.9%) patients were free from AF/AT in
group 1 compared with 81 (64.8%) in group 2 (p<0.001). In
multivariate cox regression, the ‘upgraded 2C3L’ procedure is associated
with a lower recurrence rate (HR 0.27, 95%CI 0.12-0.59). Conclusion:
Compared with the conventional ‘2C3L’ approach, the ‘upgraded 2C3L’
approach has higher effectiveness for ablation of PeAF.
ISOLATED PULMONARY CYSTICERCOSIS IN AN URBAN SOUTH AFRICAN CHILD

Published: March 2021

Cysticercosis in humans is a serious public health problem,
predominantly affecting low and middle-income countries (LMICs).
Cysticercosis, the infection with the larval form of the pork tapeworm,
Taenia Solium has high prevalence in areas where there are poor sanitary
conditions and domestic pig without adequate veterinary control. Humans
are the definitive host and pigs are the main source of infection. Human
infection occurs when pork is eaten raw or undercooked. Ingested eggs or
proglottids hatch into larvae form, which penetrate the intestinal wall
into the blood stream and migrate into different organs including
subcutaneous tissues, brain, eyes and rarely heart or lung, where they
mature into cysticerci. Pulmonary cysticercosis has been rarely
described; case reports are predominantly in adults and are usually of
disseminated disease. In children the data are very scarce, with a
single case report of a two-year old child with pulmonary infiltration,
eosinophilia and subcutaneous cysticercosis.

Tourists of the Future

Today, more and more people are travelling than ever before, with 1.5 billion international tourist arrivals recorded in 2019 and the forecasted 1.8 billion international arrivals set to be reached well before its predicted 2030 (UNWTO, 2019; 2020). Traditionally, the wealthier industrialised world has predominately been responsible for both the supply and demand of tourism. However, in recent years a gradual shift has occurred with new destinations beginning to challenge these traditional destinations. There is the expectation that 57% of all international tourist arrivals will be in emerging destinations by 2030 (UNWTO, 2017). The rise of the middle class has resulted in more of the world’s population gaining access to leisure time and the means to increased international travel. Travel experiences in the past have typically consisted of sun, sand and surf type holidays. Tourists are no longer content with these passive activities, rather seeking more experiential and engaging travel experiences instead. This suggests a change in demand from the mass tourism holidays of the 1970s and 1980s to more individualised tourist experiences (Sharpley, 2005). Drivers of change contributing to these changes in travel demand include increased globalisation along with a variety of economic, social, political, technological and environmental trends (Dwyer et al., 2008). Chapter 2 discusses the key drivers of change, along with several trends considered to have an impact on the future development of the international tourism industry. This chapter explores some of these trends further in the context of future tourist behaviour, namely smart tourism, virtual tourism, smart boredom, super sabbaticals and solo travellers.

This chapter examines the ways in which teaching and training in tourism, hospitality and events have evolved and adapted to the contemporary demands of academia and industry. It explores the development of education in tourism, hospitality and events, the contemporary factors which influence teaching and learning, and discusses the rise of Massive Open Online Courses with a particular focus on their potential application within tourism, hospitality and events curriculum. The chapter concludes by providing an overview of Open Badges and their importance in education. At the time of writing, the world has been confronted by the Covid-19 global pandemic which has caused great disruption at all levels. The impact of Covid-19 is briefly addressed in this chapter as the enforcement of social distancing measures has led to a significant increase globally in online education.
The Demise of Tourism

This chapter investigates the possibility that the tourism industry, as we cur- rently know it, will significantly change and perhaps will not exist in the future. Some topics will be discussed in the realm of plausible futures, meaning that they may not happen, however it’s a possibility and in the event it does occur, the tourism industry should be prepared. The topics discussed in this chapter include having an understanding of the reliance of natural resources in the travel, hospitality and event sectors; global population growth; food security; the impact of war on tourism; and the moral considerations associated with certain tourist experiences. Pandemics including Covid-19 are mentioned in Chapters 2, 4, 6, 7, 9, 11 and 14. The case study focuses on food security and the dangers of depleting the quantity of food around the globe, along with the availability of quality nutritional food. It also explores the changes in the types of food supplied to the tourism, hospitality and event sectors, and provokes consideration of the disparity between the wealthy and populations born into poverty.
Tracking via Geotagged Social Media Data
Authors: Hardy Anne
Published: March 2021

Over the past twenty years, social media has changed the ways in which we plan, travel and reflect on our travels. Tourists use social media while travelling to stay in touch with friends and family, enhance their social status (Guo et al., 2015); and assist others with decision making (Xiang and Gretzel, 2010; Yoo and Gretzel, 2010). They also use it to report back to their friends and family where they are. This can be done using a geotag function that provides a location for where a post is made. While little is known about why tourists choose to geotag their social media posts, Chung and Lee (2016) suggest that geotags may be used in an altruistic manner by tourists, in order to provide information, and because they elicit a sense of anticipated reward. What is known, however, is that the function offers researchers the ability to understand where tourists travel. There are two types of geotagged social media data. The first of these is discussed in this chapter and may be defined as single point geo-referenced data – geotagged social media posts whose release is chosen by the user. This includes data gathered from social media apps such as Facebook, Instagram, Twitter and WeiChat. The method of obtaining this data involves the collation of large numbers of discrete geotagged updates or photographs. Data can be collated via an application programming interface (API) provided by the app developer to researchers, by automated data scraping via computer programs, perhaps written in Python, or manually by researchers. The second type of data is continuous location-based data from applications that are designed to track movement constantly, such as Strava or MyFitnessPal. Tracking methods using this continuous location-based data are discussed in detail in the following chapter.
Tracking Tourists’ Mobility via the Internet
Authors: Hardy Anne
Published: March 2021

Tracking tourists’ mobility and migratory patterns may be conducted by collating their digital footprints via the web. Data of this sort may be sourced via apps such as Google Maps, or websites that collate IP numbers and their proximity to mobile phone towers. It may also be collected via big datasets such as ticketing websites, via mini programs such as those used by WeChat, and via non-big data sources such as blogs. This form of location-based tracking is a highly efficient and cost- effective means of understanding where consumers are located. The devastating impacts of the COVID-19 pandemic upon the tourism industry have clearly indicated the potential for tracking via the internet to assist the tourism industry. Google’s analytical data that was released publicly in March 2020 provided an excellent example of this – both in terms of the insights that can emerge from data of this type, and consumers’ perceptions of the ethics of this form of data. This chapter will explore the technique, including the types of location-based data that can emerge from websites, the conceptual learnings that have emerged from this technique, and, importantly, the ethical implications of this form of data.
