Article Citation - WoS: 3Citation - Scopus: 5Social Connectedness and Mental Health Before and During the Covid-19 Pandemic in a Community Sample in Korea(Public Library of Science, 2023-10-19) You, Sungeun; Moon, Hyejoo; Lee, Sojung; Şahin, Banu Çankaya; Caine, Eric; Ko, Jisu; Cankaya, BanuThis study compared social connectedness patterns and examined the relationships between objective or subjective social connectedness and mental health before and during the COVID-19 pandemic among community dwelling adults in South Korea. An identical online survey was administered at two time points, in 2019 prior to the onset and again in 2021. Objective (network diversity and network size) and subjective (thwarted belongingness and perceived burdensomeness) social connectedness were measured along with positive and negative indices of mental health (depression, suicidal behavior, happiness, and life satisfaction). The results indicated that among social connectedness indices perceived burdensomeness were significantly higher during the COVID-19 pandemic compared to the prior period, while network size was smaller. Subjective social connectedness was associated with all aspects of mental health consequences, either positive or negative. Among objective social connectedness, only network diversity was significantly associated with increased happiness and life satisfaction, and objective social connectedness was not associated with depression and suicidal behavior. These associations did not differ across the two time periods. The findings, both before and during the pandemic, indicated that network diversity is an important factor for positive indices of mental health and that efforts to increase subjective social connectedness are needed to decrease the risk of depression and suicidal behavior.Article Citation - WoS: 5Citation - Scopus: 9An Online Laboratory School Research on Pre-Service Mathematics Teachers’ Experiences and Mathematics Teaching Anxiety(Springer, 2022-11-04) Ölmez, İbrahim Burak; Taylan, Rukiye Didem; Pekkan, Tunç Zelha; Tunc-Pekkan, ZelhaDuring the COVID-19 pandemic, we founded an Online Laboratory School (OLS) under the roof of a university in Turkey to support students from public schools that were not technologically prepared for an online education and to provide an opportunity for our pre-service teachers (PSTs) to continue their internship by teaching online. The purpose of this research, consisting of two studies, was to examine experiences of 43 PSTs (first-, third- and fourth-years) during the OLS period of 8 weeks and how the OLS affected their mathematics teaching anxiety during Fall 2020. In the first study, we administered a survey to inquire into PSTs’ views on their experiences at the OLS, and in the second study we examined their mathematics teaching anxiety before and after the OLS experience using another survey. One main result was that the OLS experience served as an effective introduction to the profession for first-year PSTs and fourth- and third-year PSTs reported learning in-depth about online teaching in terms of the planning, teaching, and reflecting cycle. Another main result was that PSTs had mathematics teaching anxiety from “a little” to “a moderate amount” before the OLS and their teaching anxiety did not significantly change during the OLS period of 8 weeks. PSTs experienced highest mathematics teaching anxiety when they were observed and evaluated by supervisors during their teaching. The implications of these findings are discussed for teacher education programs.Article Citation - WoS: 8Citation - Scopus: 11Workers' Individual and Dyadic Coping With the Covid-19 Health Emergency: a Cross Cultural Study(Sage, 2022-09-16) Donato, Silvia; Brugnera, Agostino; Manzi, Claudia; Reverberi, Eleonora; Aksu, Ayça; Molgora, Sara; Adorni, Roberta; Morrissey, SuzyThe aim of this study was to examine workers' psychological distress during the COVID-19 pandemic as a function of their individual coping, dyadic coping, and work-family conflict. We also tested the moderating role of gender and culture in these associations. To achieve this aim, we run HLM analyses on data from 1521 workers cohabiting with a partner, coming from six countries (Italy, Spain, Malta, Cyprus, Greece, and Russia) characterized by various degrees of country-level individualism/collectivism. Across all six countries, findings highlighted that work-family conflict as well as the individual coping strategy social support seeking were associated with higher psychological distress for workers, while the individual coping strategy positive attitude and common dyadic coping were found to be protective against workers' psychological distress. This latter association, moreover, was stronger in more individualistic countries.Article Citation - WoS: 2Citation - Scopus: 2Effects of Covid-19 Lockdowns on Social Distancing in Turkey(Oxford University Press, 2022-05-23) Bilgel, FıratThis paper elucidates the causal effect of lockdowns on social distancing behaviour in Turkey by adopting an augmented synthetic control and a factor-augmented model approach for imputing counterfactuals. By constructing a synthetic control group that reproduces pre-lockdown trajectory of mobility of the treated provinces and that accommodates staggered adoption, the difference between the counterfactual and actual mobility of treated provinces is assessed in the post-lockdown period. The analysis shows that in the short run following the onset of lockdowns, outdoor mobility would have been about 17–53 percentage points higher on average in the absence of lockdowns, depending on social distancing measure. However, residential mobility would have been about 12 percentage points lower in the absence of lockdowns. The findings are corroborated using interactive fixed effects and matrix completion counterfactuals that accommodate staggered adoption and treatment reversals.Article Citation - WoS: 15Citation - Scopus: 17Does Social Influence Affect Covid-19 Vaccination Intention Among the Unvaccinated?(Cambridge University Press, 2022) Bozyel, Gizem; Uysal, Mete Sefa; Akpınar, Ege; Aksu, Ayça; Salalı, Gül DenizConformist social influence is a double-edged sword when it comes to vaccine promotion. On the one hand, social influence may increase vaccine uptake by reassuring the hesitant about the safety and effectiveness of the vaccine; on the other, people may forgo the cost of vaccination when the majority is already vaccinated - giving rise to a public goods dilemma. Here, we examine whether available information on the percentage of double-vaccinated people affects COVID-19 vaccination intention among unvaccinated people in Turkey. In an online experiment, we divided participants (n = 1013) into low, intermediate, and high social influence conditions, reflecting the government's vaccine promotion messages. We found that social influence did not predict COVID-19 vaccination intention, but psychological reactance and collectivism did. People with higher reactance (intolerance of others telling one what to do and being sceptical of consensus views) had lower vaccination intention, whilst people with higher collectivism (how much a person considers group benefits over individual success) had higher vaccination intention. Our findings suggest that advertising the percentage of double-vaccinated people is not sufficient to trigger a cascade of others getting themselves vaccinated. Diverse promotion strategies reflecting the heterogeneity of individual attitudes could be more effective.Article Citation - WoS: 6Citation - Scopus: 6Effects of Vaccination and the Spatio-Temporal Diffusion of Covid-19 Incidence in Turkey(John Wiley and Sons Inc, 2022-06-04) Bilgel, Fırat; Karahasan, Burhan CanThis study assesses the spatio-temporal impact of vaccination efforts on Covid-19 incidence growth in Turkey. Incorporating geographical features of SARS-CoV-2 transmission, we adopt a spatial Susceptible–Infected–Recovered (SIR) model that serves as a guide of our empirical specification. Using provincial weekly panel data, we estimate a dynamic spatial autoregressive (SAR) model to elucidate the short- and the long-run impact of vaccination on Covid-19 incidence growth after controlling for temporal and spatio-temporal diffusion, testing capacity, social distancing behavior and unobserved space-varying confounders. Results show that vaccination growth reduces Covid-19 incidence growth rate directly and indirectly by creating a positive externality over space. The significant association between vaccination and Covid-19 incidence is robust to a host of spatial weight matrix specifications. Conspicuous spatial and temporal diffusion effects of Covid-19 incidence growth were found across all specifications: the former being a severer threat to the containment of the pandemic than the latter.Article Online Peer Reviews: a Lasting Innovation From the Covid Pandemic?(The Global eLearning Journal, 2022) Bush, C. Jerome; Bakhtiyarov, RustamThe COVID pandemic caused a forced transition to online learning as schools were closed to stop thespread of the disease. Schools and teachers coped with this by adapting face-to-face activities to theonline environment in innovative ways. This study investigates the effectiveness of conducting peerreviews online and considers whether this innovation should be retained after the pandemic ends. It wasconducted in a small, private university in a developing country. Out of 130 students, 34 surveys werecollected (26%) that contained useful quantitative and qualitative data. The checklist forms used in thepeer reviews were compared to the subsequent draft to see the uptake of the feedback. The resultsshowed that students incorporated 72% of the peer suggestions in the next versions of their report.Overall, the peer reviews were found to be effective, motivating, and to increase confidence as a writer.Students considered the most effective way to improve writing is with a combination of peer and teachergiven feedback. Interestingly, no clear preference for face-to-face peer reviews was indicated. Therefore,it seems that conducting peer reviews online is a valid option for teachers who want to save valuableclass time. To enhance the effectiveness of online peer reviews it is suggested that teachers givesubstantial learner training prior to the peer review, provide structure such as checklists or guidelines, andincrease accountability by giving students a chance to meaningfully evaluate the comments andparticipation of their peer reviewers.Conference Object Corporate Social Responsibility Communication of Banks in the First Days of the Covid-19 Pandemic in Turkey(2021) Tosun, PetekThe purpose of this study is to examine corporate social responsibility (CSR) communication and the waysthe pandemic changed CSR communication of banks on social media at the beginning of the COVID-19pandemic in Turkey. A content analysis was made on the Facebook accounts of the biggest public, private,and foreign-owned retail banks in Turkey. The findings have shown that banks have increased their overalland health-related CSR communication during the pandemic. Besides, it was found that each bank had itsunique CSR approach and shifted its CSR activities online. Messages with CSR content got a higher numberof consumer comments than non-CSR messages. Customer interaction levels differed significantly amongmessages that included different CSR content such as health and society. This study reflects Turkish banks’CSR communication on social media, presents comparative results for crisis and non-crisis periods, andprovides analysis results about CSR communication during the pandemic. Besides, it is among the firststudies that examine the financial institutions’ social media marketing communication related to theCOVID-19 pandemic. The findings of this study may help marketing managers in designing their marketingstrategies in crisis times.Article Citation - WoS: 44Citation - Scopus: 49Population Density Index and Its Use for Distribution of Covid-19: a Case Study Using Turkish Data(Elsevier, 2021-02-01) Başer, OnurSince March 2020, many countries around the world have been experiencing a large outbreak of a novel coronavirus (2019-nCoV). Because there is a higher rate of contact between humans in cities with higher population weighted densities, Covid-19 spreads faster in these areas. In this study, we examined the relationship between population weighted density and the spread of Covid-19. Using data from Turkey, we calculated the elasticity of Covid-19 spread with respect to population weighted density to be 0.67 after controlling for other factors. In addition to the density, the proportion of people over 65, the per capita GDP, and the number of total health care workers in each city positively contributed to the case numbers, while education level and temperature had a negative effect. We suggested a policy measure on how to transfer health care workers from different areas to the areas with a possibility of wide spread.Book Part Crm in Retail Banking From Salespeople’s Perspective in the Covid-19 Outbreak(İKSAD, 2020) Tosun, PetekThe new coronavirus disease (COVID-19), which has stemmed in December 2019, has been declared as a pandemic by the World Health Organization in March 2020 and turned into a global health crisis (Liu et al., 2020). Besides wars, pandemics have been the most dangerous and fearful threats to human life throughout history. As of August 2020, the pandemic has cost more than 777,000 lives worldwide with approximately 22 million cases and it was still ongoing. Besides its devastating impact on the health systems, the pandemic has led to an unpredictable change in the economic and social environment and the business and social life.
