Article Citation - WoS: 7Citation - Scopus: 8Firm Survival in Times of Crisis: Do Innovation and Financing Constraints Matter? Insights From the Covid-19 Pandemic(Routledge Journals, Taylor & Francis Ltd, 2023) Ozsuca, Ekin AyseUtilizing survey data collected over three rounds, this paper investigates the impact of pre-COVID innovation performance, innovation type, sources of knowledge, and the moderating role of financial constraints on survival following the outbreak of COVID-19. The findings pinpoint a strong and positive link between firm survival and innovation, especially process innovation, confirming the ability of innovators to adapt to new conditions as a determinant of survival. Moreover, relying on internal knowledge is found to increase the chance of survival and adaptability to times of crisis. The results further indicate that access to finance strengthens the positive impact of innovation on firm survival/adaptation.Article Changes in the Teaching of Literature: a Study of Practices in the English Language and Literature Department at Cankaya University During the Covid-19 Pandemic(Routledge Journals, Taylor & Francis Ltd, 2022) Cakirlar, Ozkan; Uzundemir, Ozlem; Guvenc, Ozge Ustundag; Saglam, Berkem; Üstündağ Güvenç, ÖzgeDuring the COVID-19 pandemic, academics and students have had to respond to the unexpected and unplanned shift from face-to-face to online teaching. Since teaching and learning through online portals has been a new experience, this has prompted the academics in the English Language and Literature Department at Cankaya University to seek alternative and creative ideas to promote student productivity, participation and motivation. The aim of this case study is to discuss how the course materials, teaching methods and assessment have been redesigned to meet the needs of online education during the pandemic. With the examples from changes in the syllabi, student survey and sample student responses, this study also reveals how the academics in the department have had an opportunity to re-evaluate systems of teaching both on and offline and to refresh their role as instructors.Article Citation - WoS: 15Citation - Scopus: 15Psychometric Properties of the Turkish Version of the Behavioral Emotion Regulation Questionnaire (Berq)(Routledge Journals, Taylor & Francis Ltd, 2021) Tuna, EzgiThe Behavioral Emotion Regulation Questionnaire (BERQ) is a self-report measure of the behavioral strategies individuals use to regulate emotions in response to stressful or negative events. The purpose of the present study was to report on the psychometric properties of the Turkish version. The sample was recruited through courses at a semi-private university in Turkey and through social-media announcements. A sample of 320 adults (81.9% females, 18.1% males) with a mean age of 22.03 (SD = 2.73) completed the Turkish translation of the BERQ, the Emotion Regulation Questionnaire, the Difficulties in Emotion Regulation Questionnaire and the Brief Symptom Inventory. Exploratory factor analysis indicated that the Turkish version replicated the 5-factor structure of the original version; yet, a confirmatory factor analysis indicated that the original model showed an inadequate fit to the present data. Internal consistency coefficients of the subscales ranged between 0.72 and 0.88, and the test-retest reliability of subscales over a 3-week interval ranged from 0.51 to 0.70. As in the original version, we found that actively approaching and seeking social support were more adaptive strategies, whereas withdrawal and ignoring were less adaptive strategies. Results were mixed for the seeking distraction subscale. Additionally, withdrawal significantly predicted future depressive and anxiety symptoms. Overall, our results provide support for the Turkish version of the BERQ as a reliable and valid measure of behavioral emotion regulation strategies.Article Citation - WoS: 9Citation - Scopus: 15Stock Returns and Volatility: Empirical Evidence From Fourteen Countries(Routledge Journals, Taylor & Francis Ltd, 2005) Balaban, E; Bayar, AThis is a pioneering effort to test in 14 countries the relationship between stock market returns and their forecast volatility derived from the symmetric and asymmetric conditional heteroscedasticity models. Both weekly and monthly returns and their volatility are investigated. An out-of-sample testing methodology is employed using volatility forecasts instead of investigating the relation between stock returns and their in-sample volatility estimates. Expected volatility is derived from the ARCH(p), GARCH(1, 1), GJR-GARCH(1, 1) and EGARCH(1, 1) forecast models. Expected volatility is found to have a significant negative or positive effect on country returns in a few cases. Unexpected volatility has a negative effect on weekly stock returns in six to seven countries and on monthly returns in nine to eleven countries depending on the volatility forecasting model. However, it has a positive effect on weekly and monthly returns in none of the countries investigated. It is concluded that the return variance may not be an appropriate measure of risk.Article Citation - WoS: 1Citation - Scopus: 1The Effect of Different Inflation Risks on Interest Rates of the Us(Routledge Journals, Taylor & Francis Ltd, 2009) Yuksel, E.; Akdi, Y.This article examines the effect of different inflation uncertainty measures on interest rates of the US in a Fisher hypothesis framework. Generalized Autoregressive Conditional Heteroskedasticity (GARCH) specification with a time-dependent parameter model is used to obtain three types of inflation uncertainties, namely, impulse uncertainty, structural uncertainty and steady-state uncertainty. It has been observed that the impulse uncertainty has negative but the structural uncertainty has positive impact on both short-term and long-term interest rates. Both of these effects are statistically significant. The influence of steady-state uncertainty on interest rates is positive, but the level of significance depends on the inclusion of output gap. Without the inclusion of output gap, the effect is insignificant, whereas the effect becomes significant when output gap is introduced.Article Citation - WoS: 19Citation - Scopus: 25Linking Leadership Style and Workplace Procrastination: the Role of Organizational Citizenship Behavior and Turnover Intention(Routledge Journals, Taylor & Francis Ltd, 2018) Kose, Asli Goncu; Metin, U. Baran; Göncü Köse, AslıThe primary aim of the present study was to explore whether paternalistic or transformational leadership styles of supervisors were significantly related to workplace procrastination. Moreover, the potential mediation effects of organizational citizenship behaviors (specifically, civic virtue, and conscientiousness) and turnover intention in the link between leadership style and procrastination of the employees were investigated on a heuristic model. Data was collected through online surveys from 126 Turkish full-time office employees. The goodness-of-fit of the proposed model was tested using structural equation modeling and the mediation analysis was performed by bootstrapping. As expected, transformational leadership and organizational citizenship behaviors were negatively related to workplace procrastination. However, there was no significant link between paternalistic leadership and procrastination. Moreover, turnover intention and organizational citizenship behaviors did not mediate this relationship. These findings suggest that transformational leadership style could be a more effective style for diminishing employees' excessive nonwork related behaviors.
