Dry, Salty, and Habitable: The Science of Alkaline Lakes
Authors: Tutolo Benjamin M. , Tosca Nicholas J.
Published: May 2023

Alkaline lakes are incredibly dynamic, unique, and fascinating biogeo-chemical environments that have remained distinctive features of Earth’s evolving surface over much of its history. Understanding these evaporative surface waters, their exceptionally productive ecosystems, and their rare sedimentary deposits requires an inherently interdisciplinary approach at the intersection of hydrology, geology, and biology. The discipline-spanning articles in this issue evaluate the diverse characteristics that make these dry, salty, and habitable environments so valuable in unraveling the history and evolution of Earth’s surface, and in following the arc of habitability on ancient Mars. Here, in this introductory article, we summarize the characteristics and importance of alkaline lakes with the hope of attracting you, too, to join in our fascination with them.

To that end, the study drew on original data from the Survey of the Welfare Status and Needs of Jeonnam Island Residents conducted by the Jeonnam Welfare Foundation from October 11 to November 1, 2017. The respondents (N = 500) were residents of inhabited islands in Jeollanam-do. The data were analyzed using SPSS version 26.0. The results indicate a partial mediating effect of social capital on the relationship between connection to the mainland and perceived life satisfaction. Based on these results, the study makes a number of practical and policy suggestions.
Ballina’s Big Prawn, local fishing heritage and place branding
Authors: Hayward Philip
Published: May 2023

The Big Prawn statue erected in Ballina, on the north coast of the Australian state of New South Wales, in 1989 belongs to a genre of roadside ‘big things’ that commenced in Australia in the 1960s. The statue has come to be a prominent — if frequently contentious — landmark within the town and an icon of it for tourists. Its symbolism reflects Ballina’s status as a coastal location with a small fishing fleet and dedicated harbour and magnifies that aspect as a projection of the town to both visitors and a general social media public. As such, the Big Prawn has both a cultural ‘life of its own’ and a relationship to Australia’s national circuit of roadside big things and with other symbols of Ballina mobilised by the town council and its tourism promotion. The article provides a history of the development, prominence and impact of the Big Prawn in cultural media, its relation to cultural debates about aesthetics and heritage in Australia and the manner in which its sign can be understood to operate within a coastal location heavily dependent on tourism income.
A Historical Study on Sea Routes of the Zhoushan Archipelago in Ancient China
Authors: Yao Yanbo , Feng Dingxiong
Published: May 2023

The Zhoushan Archipelago occupies an important position on the ancient Maritime Silk Road, as its strategic position along the Coastal China makes it a crucial passageway for vessels travelling southward and eastward, and thus throughout history, the Zhoushan Archipelago has been an important hub for international exchanges, facilitating numerous sea routes to connect China with the rest of the world. All these sea routes have been well-documented in the historical literature. In this paper, the various sea routes of the Zhoushan Archipelago recorded in the historical literature have been reviewed in detail and drawn on the charts to highlight in an explicit and visual way the importance of the Zhoushan Archipelago in the ancient maritime Silk Road and its role in facilitating international exchanges. It can be argued that there are both natural and cultural reasons for the Zhoushan Archipelago to be referred to as the “Maritime Dunhuang” along the Maritime Silk Road. By reviewing and mapping the diverse sea routes of the Zhoushan Archipelago in nncient China, we can gain a better understanding of the historical significance of the Zhoushan Archipelago in international exchanges and recognise the pivotal role it has played in shaping the world we live in today.

Authors: Ismail Khodijah , Setiawan Tri , Lestari Febrianti , Habibah Sayyidah Nur
Published: May 2023

This study analyzes how social networks can connect and interact to strengthen food accessibility for poor households on Mapur Island, one of the small and outermost islands in Indonesia. Data collection used interviews with eighteen recipient households of the Family Hope Program (PKH) and Focus Group Discussions with eighteen key informants. Data were analyzed using R analysis and social network analysis. This study found that the level of access to food for PKH households and their social networks was very low and short. His dependence on rice assistance from the government and being in debt to ‘Patron’ became very strong. Of all identified communities, the same pattern was found, and a strong mutual relationship was with ‘Patron.’ The role of ‘Patron’ in the food access network is an intermediary and central role that connects many entities and activities to meet community needs. The interaction between the Regional Logistics Agency stopped at the liaison between the ‘Patron’ and the village government that distributed the assistance. The village food access network is very dependent on the network owned by ‘Patron.’ Government intervention through policies and strengthening food institutions can play a key role in helping to facilitate access to food needs on the island.
Qualitative determinants of wine demand: an exploratory analysis of two Sicilian wines “Catarratto” and “Nero d’Avola”
Authors: Sgroi Filippo , Modica Federico
Published: May 2023

This article analyzed the socio-cultural representations associated with two Sicilian wines, Catarratto, and Nero d’Avola. The study was carried out in the area of western Sicily, where most of the wine growing is concentrated. In particular, for ‘Catarratto’, the research was conducted in the area of the Gulf of Castellammare in the province of Trapani, an area particularly suited to the cultivation of the ‘Catarratto’ vine from which the white wine is obtained; for ‘Nero d’Avola’, the research was conducted in the area of Menfi in the province of Agrigento, an area particularly suited to this black vine. Our objective was to determine how the players in the wine chain, and who indirectly deal with wine, construct their mental model relating to wine to suggest to companies the appropriate wine marketing actions to take to increase their competitive advantage. To achieve the objective of the research, ten focus groups consisting of wine consumers, teetotalers, wine opinion leaders, wine merchants, wine shop owners, medical doctors, and food experts were conducted. During the focus group, we gave these subjects a document in which they had to explain what wine evokes in them. The results of the research confirm that wine is a complex food product whose consumption evokes sensations, memories, and pleasures. The study provides an important source of knowledge on the current cultural significance of wine and its consumption in these two areas of Sicily. Therefore, the study highlighted the quality of these two Sicilian wines can guarantee competitiveness at the company and sector levels.
ÇEVRENİN KİRLETİLMESİ SUÇUNDA KAMU GÖREVLİSİNİN CEZA SORUMLULUĞU
Authors: BALCI Meral
Published: May 2023

Çevreye karşı gerçekleştirilen hukuka aykırı fiiller, günümüzde ceza hukuku boyutuyla da önem taşımaktadır. Çevrenin korunmasında idare hukukunun önceliğinin bulunması, bu alanda ceza hukukunun kapsamının belirlenmesi bakımından etki etmektedir. Çevre suçları, çevre ceza hukukunun idari bağlılığı nedeniyle klasik suç tiplerinden farklılık göstermektedir. Çevre suçunun tipikliğinde idare hukuku temeline dayanan yükümlülük veya gerekliliklere atıf yapılması nedeniyle, çevre suçlarının değerlendirilmesinde idare hukuku esaslarının göz ardı edilmesi söz konusu değildir. Özellikle kamu görevlilerinin üçüncü kişilerin çevreye zararlı davranışları nedeniyle cezai sorumluluğu sorunu çevre ceza hukukunun önemli meselelerinden biridir. Çevreye karşı gerçekleştirilen müdahalelerin genellikle izin veya ruhsat şartına bağlı olması, çevre suçlarında bu izni veya ruhsatı veren kamu görevlisinin sorumluluğunun belirlenmesi bakımından önem taşımaktadır. Bu bağlamda çevre suçlarında ilgili kamu görevlisinin kasten hatalı ve fakat geçerli bir izin vermesi ile verdiği hukuka aykırı izin veya ruhsatı geri almada ihmal göstermesi ön plana çıkmaktadır. Belirtilen konular, çalışmanın eksenini oluşturmaktadır ve çalışmada büyük ölçüde Alman doktrininde konuya ilişkin ileri sürülen görüşlerden yararlanılacaktır. Bununla birlikte kamu görevlisinin idare hukuku temelinde sorumluluğuna ilişkin inceleme yapılmayacaktır.

Purpose. To determine the subspecies and variety/sample of garlic with the best nutritional value by analy­zing the difference between nutritional value indicators and their variation according to the time of planting (winter or spring).
Methods. During 2020–2022, in field conditions (Uman, 48°46’N, 30°14’E) were studied 25 breeding and local forms of garlic (9 – winter bolting; 9 – winter non- bolting; 11 – spring, among which samples No. 14, 33, 43 and 44 were determined to be suitable for planting in autumn and spring. For the analysis of the obtained results, generally accepted methods of genetic and statistical analysis were used.
Results. Varieties and samples with high protein content were selected – ‘Giovanna’, ‘Sofiivskyi’, No. 14, 43, 54 and 55; with high calorie pulp – ‘Apollon’, No. 14, 27, 33, 43 and 57 (can be the starting material in the process of crea­ting highly nutritious varieties for the needs of the food industry). With regard to nutritional elements, the accumulation of proteins in the pulp of winter non-bolting garlic was 4.1 and 20.9% higher than that of winter bolting and spring garlic, respectively. The highest fat content was found in the pulp of winter bolting and spring subspecies. Spring garlic accumulated the most carbohydrates, while winter non-bolting garlic accumulated the least. At the same time, the energy value indicator of spring garlic was 130.03 kcal/100 g raw pulp mass, which was 3.1 and 12.6% higher than that of the winter bolting and winter non-bolting subspecies, respectively.
Conclusions. The results of the study showed that winter garlic was significantly superior to spring garlic in terms of protein content in the pulp. The difference in fat content was insignificant. Spring garlic pulp was characte­rised by a significantly higher amount of carbohydrates and therefore the highest calorie content.

Published: May 2023

Sağlık hizmetleri bir bütün olarak düşünüldüğünde akla ilk gelen hizmetlerden bir tanesi hastanede kalınan süredir. Bireylerin hastanede kaldıkları süreye birçok farklı faktör etki eder. Bu çalışmada bireylerin hastanede kalış süresine etki eden faktörler sayma regresyon modelleri kullanılarak incelenmiştir. Ayrıca, sayım verilerinin modellenmesi için Bell regresyon modeli olarak adlandırılan yeni bir regresyon modeli yakın zamanda Castellares vd. (2018) tarafından istatistik literatürüne kazandırılmıştır. En sık kullanılan sayma regresyon modeli olan Poisson regresyon modelin aksine, Bell regresyon modeli aşırı yayılıma izin vermektedir. Ayrıca Bell dağılımı tek parametreli olduğundan çeşitli istatistiksel çıkarımları yapmak aşırı yayılıma izin veren diğer bir model olan negatif binom modeline göre daha kolaydır. Bu nedenle, yeni model aşırı yayılımlı veri setlerini modellemek için iyi bir seçenektir. Bell regresyon modelinin TÜİK tarafından yapılan Türkiye Sağlık Araştırması veri seti kullanılarak bir uygulaması verilmiştir. Bell regresyon, Poisson ve Negatif binom regresyon modelleriyle karşılaştırılmıştır. Elde edilen bulgular, Bell regresyon modelinin kullanılan veri seti için diğer regresyon modellerinden daha iyi uyum sağladığını göstermektedir. Bu sonuç Pearson ve Rasgele Kantil artık türleri incelenerek desteklenmiştir.
Airport Common-Use Check-in Operations: A Novel and Efficient Model
Authors: DALKIRAN Alper
Published: May 2023

This paper examines the capacity problems of common-use environment service improvement
and airport passenger services in line with information technology (IT) issues. There are many
time-critical processes in the airport terminal for the necessary airport passenger flow processes
that IT service design aims to support it. Many flow processes can be designed under several
functions while international, domestic, or general aviation cases. The current approaches have
been based on the standard industrial methods based on the Information Technology
Infrastructure Library (ITIL) practices. However, this infrastructure library practices’ distinct
general industrial foundations and airport time-critical processes could not fit customer
expectations. This research offers an approach by adding a pre-layer with a user certification
rather than fixing the problems on the ground. Although the proposed novel model does not
conflict with the ITIL practices, it primarily develops the practices by coinciding with them a
certificated training of end users to establish a positive passenger experience and helping the
profitability of the airport. The offered model simulation results show that the Airport IT
Service helpdesk and field team instantaneous utilization average was reduced from 96% to
28%, and the field team queue duration during the airport peak hours was 26 minutes to 2
minutes. This study demonstrates that the airport IT support service design should be reconsidered during its passenger service operation.

Evaluation of the Tpeak-Tend Interval as an Arrhythmogenicity Index in Graves' Disease
Authors: Kirac Cem Onur , Sirikci Vehbi , Findikli Huseyin Avni
Published: May 2023

Introduction.Graves’ disease is the most common cause of hyperthyroidism. The mortality rate increases by 20% in hyperthyroid patients; cardiac problems are the leading cause of death and arrhythmia is the most common cardiac complication.

Our study aimed to evaluate the corrected QT interval (QTc), the Tpeak-Tend interval (Tp-e), and the Tp-e/QTc ratio to predict arrhythmia risk in patients with Graves’ disease.

Methods. The study included 64 patients with Graves’ disease and 57 euthyroid controls. The 12-lead electrocardiograms of the individuals under study were evaluated. The QTc interval, the Tp-e interval, and the Tp-e/QTc ratio of all participants were determined and statistically evaluated with thyroid stimulating hormone (TSH), free triiodothyronine (fT3) and free thyroxine (fT4) values.

Results. Tp-e (p < 0.001) and QTc (p < 0.05) were significantly prolonged in the group of patients with Graves’ disease as compared to the control group. Heart rate was higher in patients with Graves’ disease as well (p < 0.05). Correlation analysis in patients with hyperthyroidism demonstrated that Tp-e (r=0.372, p=0.002), QTc (r=0.291, p=0.020), and fT3 levels were significantly and positively correlated. Similarly, Tp-e (r=0.271, p=0.030), QTc (r=0.259, p=0.039), and fT4 levels were significantly and positively correlated.

Conclusions. We observed a significant prolongation of the Tp-e and QTc intervals with the increase in fT3 and fT4 levels. On the other hand, our study demonstrated that the sensitivity and specificity of Tp-e in the prediction of hyperthyroidism were 70.3% and 70.1%, respectively (AUC=0.724 (CI: 0.629-0.818)), the optimal cut-off value=83.5 ms). The Tp-e interval, which has recently been used as one of the arrhythmogenicity indices, may be an indicator of arrhythmia risk in patients with Graves’ disease.

Authors: Izgi Eda , Mollaoglu Nur
Published: May 2023

Objective. This study aimed to assess Turkish dental students’ awareness of and attitudes toward dental implant therapy, as well as the effectiveness of dental implantology lecture from their point of view.

Materials and Methods. This study used a cross-sectional online survey. A total of 425 third-, fourth- and fifth-year dental students enrolled in Gazi University School of Dentistry during the 2020-2021 academic year were invited to participate in the survey anonymously and voluntarily. Following the descriptive part (age, gender, and education status), all the participants were asked 11 questions.

Results. Total of 415 questionnaires were analyzed. The 3rd-year students stated that they were“ poorly” informed about dental implants (n=88, 64.7%), while the 4th- and 5th-year students were“ moderately” infromed (n=78, 54.2% and n=60, 44.4%, respectively) (p < 0.001). All the students were believed that they needed to get more information during their undergraduate studies (p < 0.01). More than half of all students preferred to have PhD or speciality training after graduation (p > 0.05). Approximately 80% of all students believed that dentists should receive specialized training in order to practice implant dentistry (p > 0.05).

Conclusions. The results of this study show that some Turkish dental students find DI treatment a difficult operation and that they do not know enough about it. As a result, it is anticipated that improving the current curriculum will contribute to the course success and make dental students feel better prepared for dental implantology following graduation.
“MedEd” on Twitter: A Social Network Analysis
Authors: Iqbal Shazia , Ahmad Shahzad , Samsudin Mohd Ali , Lodhi Saood Khan , Manji Salima Naveed
Published: May 2023

Background. In the current era, Twitter is an increasingly popular tool for the dissemination of information as a social media voice. Social media is a valid, but underutilized, education tool at medical education institutions. Social media technologies provide opportunities for the presentation of information in alternative and multiple formats to enhance engagement, content creation, and motivation for individual and collaborative learning.

Objective. This study examined the type of social structure and sub-clusters do exist regarding “MedEd” on the Twitter network. Additionally, it determined the top opinion leaders in these networks and which type of topics generates users’ interest regarding “MedEd”.

Methods. This study applied NodeXL to analyze the results and retrieved Twitter data on November 1, 2022 by using the keywords “MedEd”. The data were saved and interpreted in the “vertices” and “edges” on the NodeXL worksheets.

Results. We found that the top opinion leader (vertex) “Cryptovitas” had the highest in- betweenness and out-degree centrality. “Innov_medicine” had the in-degree centrality for networks. “In-Degree” and “Out-Degree” are the count of Tweets an opinion leader gets and forwards messages out, correspondingly. The study found that although “Cryptovitas” had the highest in-betweenness centrality, “taylorswift13” had the maximum number of followers (91,523,045) with in-betweenness centrality of 0.0. This indicates that the vertex having maximum influence with the largest number of in-betweenness centrality has not linked with several followers.

Conclusions. Using Twitter embodies a potential prospect to engage the medical education community. The content of top networks’ tweets was around the number of “MedEd” innovations with the potential to significantly improve medical education delivery and innovative technologies in healthcare services. There is no link between the number of followers and in-betweenness centrality to influence the strength of social media voice. Although clinical and social tweets were there, not much was discussed regarding the curriculum reforms, continued professional development, technical issues in MedEd, and assessments. This triggers the insistence for rapid and innovative adaptations to the new learning environments and remarkable revolutions in medical education, including the encouragement of evidence-based education. The Twitter discussions promoted a research network circulating a wide range of informative innovations and collaborations.

Authors: Dan Zhu , Subramaniam Geetha , Qin Xie
Published: May 2023

In China, the number of private higher education institutions (HEIs) has been increasing rapidly in recent times. However, an upward trend is noticed among teachers leaving the HEIs. As teachers’ life constitutes both personal and work life, this micro-level study paper examines 100 teacher turnover decisions by examining personal and institution factors based on the Two-Factor Theory. Using ANOVA and independent-t-test, it examines how teacher’s demographic factors affect their decision to leave the institution. The study hopes to contribute to policymakers understanding on teacher turnover so as to mitigate this phenomenon by improving their job satisfaction and quality of life.

Authors: Subramaniam Geetha , Ungku Affandy Ungku Aqilah , Hasan Khan Rubaiyet , Aiping Liang
Published: May 2023

The Movement Control Order (MCO) was imposed in Malaysia in March 2021 due to the Covid-19 pandemic. This six-month control led to a substantial psychological impact among Malaysians. Using a quantitative survey based on the DASS-21 instrument, 400 Malaysians answered a questionnaire to examine whether demographic factors, risk perception, individual behaviour, mental health and media usage affected the psychological impact of Malaysians during COVID-19. Findings indicate that COVID-19 did impact Malaysians more due to the movement constraint. Besides contributing to the body of knowledge, this study shows that workplace policies that affect quality of life need immediate attention.
The formation of sensory life discourse in the conditions of “Other” sociocultural experience
Authors: Safonik Lidiya
Published: May 2023

The article discusses the study of discourse related to sensual life within the context of a different sociocultural experience. The formation of this discourse is said to be influenced by legitimizing the horizontal principle in social relations, which is mainly constituted by research and developmental epistemic and discur-sive influences on the social, political, and cultural situation in society. The author employs a methodological procedure to differentiate between sensory perception and sensory understanding at the level of emotional intellect, highlighting the indi-vidual contributions of each in shaping the discourse on sensual life. It is conclud-ed що the request for the constitution of the existential meanings of the organization of life is growing under the influence of the growth of the degree of individual freedom of human beings and the formation of an open communicative space of life. They are formed in the field of voluntary horizontal actions, prompting the person to self-activation and sense finding. Sense is associated with human sensation, sensitivity and perception “at the level of the senses” and physicality "at the level of intelligence”. Meaning at the “sense level” is manifested by “common sense” and the right direction in life, and “at the intellectual level,” meaning is determined by reflective thinking, relevant discursive ethical practices and worldviews as well as cognitive orientations.
The post-truth discourse and the politics of memory in the contemporary media spaces
Authors: Mieliekiestsev Kyrylo
Published: May 2023

This article concerns the emergence, definition, and characteristic of the phenomenon of “post-truth” and how its characteristics are used in connection with historical narratives by various political forces for their own goals. The article’s goal is to identify how historical narratives are used by the spreaders of post-truth for various results in domestic and foreign policy, or, in the case of the post-truth spreader being a contesting politician vying for power, for electoral support. The research utilizes historical-narrative and historical-comparative methods, alongside methods of discourse and content analysis. After reviewing the literature, it is observed that from the point of view of historical politics, the methods of spreading the post-truth pose a tempting prospect of ensuring the ideological unity of the nation (or a part of it). The creation of an ideological and informational climate in which history consisted only of the heroism of "Us" and the various affronts and capture of “our old territories” by "the Other" contributes to internal stability. However, such historical politics, while useful in an “information bubble” in domestic policy, can be easily exposed and deconstructed by the neighboring powers decried as “the Other”, blamed for various historical grievances (in the case of a reigning regime using post-truth historical narratives), or by political rivals debunking false claims (in the case of a contesting political force using such narratives in a democracy). The post-truth relies on charisma and cognitive bias, rather than specific historical knowledge, and can be used to strengthen existing political support, more so than converting others. Post-truth accelerates the involvement of media consumers and the growth of their confidence in the correctness of the ideology. However, regardless of its utilitarian positives for political forces, a choice in favor of post-truth is a voluntary choice in favor of misinformation, anti-intellectualism and deception.
Network Strategies in the Discourse of Education: Advantages, Disadvantages, Prospects
Authors: Ishchuk Nataliia , Vasiuk Iryna
Published: May 2023

The article summarizes the theoretical and methodological basis of transformation of the modern educational space from the standpoint of subordination to such goals of information society as the improvement of “human capital” and the education of an “informational person,” the formation of a “knowledge economy,” and the formation of a new paradigm of interpersonal communication. In the context of the specified goals, the specifics of development of the educational space in information society and the decisive role of the Internet technology in this process were investigated. The role of remote digital education is outlined and the ambivalence of its influence on the student’s personality in the discourse of education (self-education) and upbringing is substantiated. It has been proven that both its advantages and disadvantages arise not only from the peculiarities of the Internet technology, but also from the anthropological peculiarities of the perception of information on the Internet. Its mostly positive educational and mostly negative ethos potential is systematized. The security mission of the Internet is extremely valuable, which is confirmed by the examples of the recent Covid-19 pandemic and the current educational situation in Ukraine under the conditions of war.
Stereotyping of the crimean tatar people’s image as a problem of interethnic communication in ukrainian society
Authors: Kutsyk Ruslan , Khokhlov Denys
Published: May 2023

With the transition of the Turkic-speaking peoples to a settled way of life in the eastern steppes of Europe, stereotypes were increasingly established in European public opinion, which determined the stereotyped and often unfair perception of the “steppe” peoples, including the Crimean Tatars, several centuries earlier. This problem is especially relevant for Ukraine, whose territory has become a place where different civilizations, cultures and religions collide. Considering this, an important task at the present stage is to overcome worldviews and prejudices that complicate the process of interethnic communication and the establishment of a dialogue of cultures. The proposed article examines the main features of the process of stereotyping the image of the Crimean Tatar people as a factor influencing interethnic communication in Ukraine. On the example of folklore and classic literature, as traditional relayers of the public consciousness of Ukrainians, the main negative markers-pronouns that were used to designate the Crimean Tatar people were determined. The main reasons that contribute to the stereotyping of the Crimean Tatar people’s image and hinder the development of efficient communication practices have been clarified. In this context, special attention is paid to the study of the historical and religious factors’ role. The nature of social interaction and conflict-genicity between Crimean Tatars and pro-Russian forces in the Crimea before the occupation is outlined. The impact of modern political events on the change in the image of the Crimean Tatar people is determined. The main measures that were implemented in order to overcome prejudices against the Crimean Tatars and to establish efficient and positive interethnic communication inside the Ukrainian society are outlined.
