The purpose of this paper is to analyze the correlation between the Twitter activity of two airline companies and their stock performance at the Istanbul Stock Exchange (BIST).

Overall, 113,018 tweets were divided into 34,152 semantic and 78,866 share tweets. Semantic tweets are tweets mentioning company’s products or services and were labeled manually and with deep learning models. Share tweets were divided into 13,618 relevant and 65,248 irrelevant tweets.

A positive correlation was found between share tweets and stock performance. Semantic tweets did not display a correlation with stock performance. Relevant share tweets displayed as a strong correlation as all share tweets for one company. Also, the manual labeling of 8,000 tweets led to the discovery of many insights related to service provision in the airway industry, management of digital support channels, management of reputation on social media and using Twitter as a customer support platform.

Relevant share tweets comprise only 20% of all share tweets for one company and show the same level of correlation with stock performance. This means that the efficiency of business intelligence solutions created to monitor Twitter activity can be improved five times by saving computational power, network bandwidth and data storage.

Previous research has analyzed all Twitter activity taken together. By dividing tweets into semantic and share tweets, this paper illustrates that it is, in fact, share tweets that are correlated with stock performance and not semantic tweets.

The purpose of this paper is to evaluate awareness and perception of GM foods of Turkish consumers living in Istanbul, Turkey.

A consumer survey consisting of 23 questions has been prepared. Totally 1,315 people participated in the survey. Awareness of the consumers about genetically modified organisms, willingness to purchase GM foods, acceptability of GM foods by consumers and legislations and information sources were assessed in the questionnaire. Nonparametric test were applied in order to unravel demographic differences.

The results of the survey showed that consumers generally know what genetically modified organisms (GMOs) are, but they do not have enough information about the genetic modification process. The main concerns of consumers about GMFs are their carcinogenic effects to human. In addition, corn was found to be the most concerned GMF. The usage of GMOs in health sector and in preventing environmental pollution were the most approved areas by the consumers, whereas the majority of consumers disapproved the use of genetic modifications in food applications.

A limitation of this study is the sample including high percentage of educated young consumers. Hence, the survey can be improved and applied to higher number of participants living in different regions in Turkey for being more representative for all Turkish consumers.

Some suggestions for food producers and food policy makers are also provided in this study.

There has been little research concerning Turkish consumers’ attitude and knowledge towards gene technology and GMFs. Also, there has not been a similar survey in the province of Istanbul.

This study intends to systematically review empirical evidence on transformational school leadership (TSL) in a centralized educational context.

The study includes a topographical mapping and a narrative review of thirty-seven research articles published in Turkey between 2000 and 2021. The review strategy included systematically searching the Turkish Academic Network and Information Center (ULAKBIM) and Scopus. The Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) flow diagram guided the review and reporting process.

Three key themes emerged: (1) perceptions, attitudes and behaviors; (2) psychological resources, learning and innovation and (3) school climate and culture. The results indicated that the research evidence on TSL in the review did not correspond well with the evidence on TSL in non-Western contexts. The authors also discussed the state of research narratively to provide an overview of the topical foci and methodological and conceptual trends.

First, although the databases of the study are claimed to be regularly updated locally, these two search databases may inevitably have missed some journal articles relevant to the inclusion criteria. A possible solution is to include more databases like ERIC, PsycArticles, SAGE, ScienceDirect, PsycINFO, Web of Science and ProQuest. Second, the authors decided to limit the exploration of journal articles on transformative leadership to peer-reviewed journal articles. The authors might have missed a wider range of insights available in book chapters, books, research papers, dissertations and gray literature. Third, as there were many levels of research foci, the authors did the coding on research foci and methods. However, the approach may not allow authors to explore the relationships between research foci and method design. One possible solution is to do all coding in one file so that more complex analysis can follow. Finally, the authors agree that TSL is only one leadership style that is related to leadership effectiveness and that effective leadership is multi-faceted and requires a combination of leadership styles. Accordingly, the evidence in the study sheds light on only one dimension of leadership effectiveness.

Our review is part of an effort to demonstrate the importance of a culturally-situated understanding of TSL and to develop a globally validated knowledge base. It identifies and summarizes research in a non-Western school context defined by centrality, lack of autonomy and accountability.

On March 11, 2020, the World Health Organization declared the COVID-19 outbreak a global pandemic. The policy responses to this outbreak have caused many impacts on our daily life and economic activities around the world. Also, this outbreak has affected financial reporting practices of the firms. Thorough financial reporting in such uncertain times plays an essential role in providing qualitative financial information. It is very important for a firm to increase transparency and report on the impacts of possible risks in times of uncertainty. Furthermore, stock markets may react to COVID-19 as they have already responded to major events like disasters, news, environmental and political events. This study investigates whether and how firms’ providing information about COVID-19 pandemic in their financial reports plays a role in explaining the stock market reactions. For this, annual reports of companies included in BIST-100 index in Turkey is used to analyze the capacity for detecting risks early and determine whether there is an association between early reporting about COVID-19 and the stock risk.

This study aimed to explore the adaptations and perspectives of hotel managers regarding green and smart hotel technologies within the context of sustainability.

A comprehensive literature review guided the formulation of this study, followed by face-to-face, semi-structured interviews with hotel managers. A total of 17 prepared questions were finalized after examination by two expert academicians. The responses were analyzed using qualitative research methodology and the results were weighted using the step-wise weight assessment ratio analysis (SWARA) method.

Interviews with sustainability and operational managers yielded insights into environmentally friendly practices and strategies such as reducing energy and water consumption, waste and chemical reduction, supporting local entrepreneurs and adopting smart technologies. These factors are crucial in eco-friendly hotels. According to the SWARA analysis, 'reducing energy consumption' is the most effective criterion.

This study offers insights into green and smart hotel management by focusing on the perspectives of hotel managers with a small sample. In future studies, research with larger samples on customer perspectives and the effect of hotel selection is recommended.

This study offers insights to hotel managers on energy conservation and customer satisfaction enhancement through green and technological applications. These technological applications can improve hotel service quality and provide personalized experiences, fostering customer loyalty.

This pioneering study focuses on the intersection of green and smart practices in hospitality. By intertwining the often separately discussed concepts of “green” and “smart,” this study presents a novel approach to the sustainability practices in the hospitality industry, holding a key position, especially in Turkey. Implementing these concepts can yield environmental and economic benefits, offering invaluable insights to hotel managers and policymakers into integrating smart technologies with sustainability.

The aim of this study is to determine the preferences to participate in diabetes screening program of women with gestational diabetes mellitus (GDM) in postpartum period.

The data of retrospective and descriptive study were collected using “Individual Identification Form” and “Information Form for the Screening of Diabetes in the Postpartum Period” from 151 women in referred to obstetrics and gynecology clinic of a university hospital in Turkey.

Only 21.9% of women had diabetes screening in postpartum period and 21.2% of the participants were diagnosed with type 2 diabetes. It was determined that the participants mostly participated in screening because of the diabetes history in their family (30.3%). Women who had diabetes screening in postpartum period had lower level of education than those who did not and their level of knowledge about the screening in postpartum and the history of abortion were higher (p < 0.01).

The rate of participation in the screening for diabetes in the postpartum period is very low in pregnant women diagnosed with GDM. It was determined that the educational status, history of previous abortion and knowledge level of the women were factors that prevented participation in diabetes screening. This research is original because there are inadequacy of studies examining determining the participation status of pregnant women with GDM to diabetes screening in the literature. This study will contribute to health professionals in order to improve preventive factors and increase the participation of pregnant women with GDM in diabetes screening in the postpartum period.

The purpose of this paper is to investigate the causes, processes of writer’s block experienced by a group of classroom teacher candidates and its impact on them.

The phenomenological design, which is a qualitative research design, was preferred in the research since it was aimed to investigate the causes, processes of writer’s block experienced by a group of classroom teacher candidates and its effects on the students.

As a result of the data analysis, it is possible to suggest the limitations of subject and time, problems in the process of writing teaching since primary school, anxiety of being controlled and assessed by grades, fear of being criticized, negativity of classroom settings, lack of information about writing, not being able to read and shortcomings in the vocabulary as the causes of writer’s block.

The research has some limitations. First, the research is only in the phenomenology design. Quantitative research is needed to determine the more common effects of outcomes. The other one is a limitation on the participants. A group of adult teacher candidates constitute the participants of this research. Writer’s block of students at different age levels can be examined longitudinally. Nevertheless, the results of the research have the theoretical implications for teaching writing. It specifically guides to understand and eliminate negative affective factors related to writing.

The results of this research have practical implications in terms of classroom practices. The results of the study show that there are practical implications for what should be considered in classroom writing teaching and to prevent the writer’s block.

Writer’s block is an affective state and the examination of it is important in terms of writing instruction. Many students suffer from writer’s block. However, this subject is neglected by writing researchers and educators. The authors expect the results to guide teachers and writing education researchers. Because of these reasons, this study is important and gives good contribution to literature.
