Item Digital Gaming Trends of Middle-Aged and Older Adults: A Sample from Turkey(2023) Secer, Ilmiye; Us, Elif OykuBackground Although the gaming habits of children, adolescents, and younger adults have been investigated in Turkey there has been less emphasis on the gaming patterns of middle-aged and older adults. The current study therefore investigated middle-aged and older adults' digital gaming habits, the aspects of digital games that they believe are enjoyable and any perceived psychological and cognitive advantages. Methods Of the 177 middle-aged and older adults aged between 55 and 85 years (M = 62) living in Turkey who partook in the study, data from 140 participants were analyzed. Participants completed the 'Demographic Information Form' and Engagement with Digital Games Questionnaire' via a Qualtrics link that was distributed on social media platforms and using the convenience and snowball sampling technique. Results Findings of this study showed that out of the 57 digital game players, the majority (N = 34) reported to play puzzle games such as Candy Crush. Moreover, gamers indicated that they believed digital games had psychological and cognitive benefits. Conclusion Overall, the findings of the current study revealed that middle-aged and older adults enjoy playing digital games for fun, stress relief, and as a mental exercise regime.Item Post-migration ecology in educational leadership and policy for social justice: Welcoming refugee students in two distinct national contexts(2022) Arar, Khalid; Orucu, DenizUtilizing the post-migration ecological lens and the synthesized model of culturally relevant leadership formed by the authors, we aim to compare and analyze the policy outlines and school leadership responses to refugee education in Turkey and Germany; as the two main hosts of the largest number of refugees. Through comparative phenomenology, we draw on the semi-structured interviews, observations, and document analysis of policy papers in each context. Although both states employ an open-door policy, their educational policies show stark contrasts. The German schools benefit from the systematic guidance whilst in Turkey they find their ways through rule of thumb with colleagual collaboration within and across schools. We reckon this study would provide a space for collaboration and benchmarking between different contexts as well as illuminate on the policy-making processes, school-level practices, and research in this area.Item The efficiency of primary sovereign bond markets in Turkey: The so-called Fisher puzzle reconsidered(2022) Sunal, Onur; 0000-0002-3972-4060Many prior studies have tested the validity of the Fisher effect, with results proving controversial, regardless of the econometric models, country groups, or time spans chosen. Therefore, to solve the so-called Fisher puzzle, this study aims to reveal whether current interest rates, which are set in the primary bond markets, carry information about actual inflation rates when the conventional direction of causation is reversed, using monthly Turkish data from the 2010-2018 period. In line with our expectations, we found a significant long-run coefficient (0.92), which indicates that changes in interest rates are rational expectations of changes in current inflation rates, though a full Fisher effect was not observed. Moreover, the short-run coefficients were also significant, which highlights the fact that the unanticipated movements in these variables act as early signals of persistent future price-level changes. Therefore, monetary authorities should respond rapidly in the short run using rules-based proactive policies to curb long-run volatilities, which also restrict the power of estimations, as market participants tend to assign higher risk premiums to bond yields when prices are expected to surge.

In Turkey, solid-organ transplants started in 1975; however, routine pretransplant tuberculosis risk screening programs are still not established. Therefore, we conducted a meta-analysis of tuberculosis prevalence, clinical forms, and prognosis of tuberculosis in solid organ transplant recipients. Materials and Methods: We searched PubMed, Web of Knowledge, Google Scholar, EBSCOhost, and Scopus databases in English and Turkish Medical Index of Turkish Academic Network and Information Center, Turkish Citation Index, Turkish Medline, Central Thesis of ULAKBIM databases in Turkish (from inception until December 2018) for national and international reference lists of all relevant papers. We used standard methodological procedures (Preferred Reporting Items for Systematic Reviews and Meta-Analyses 2009). Results: We found 199 published studies in English and 26 in Turkish. After exclusion of noneligible studies, there were 10 retrospective research articles and 16 case reports. There were 148 (3.2%) tuberculosis cases with 4553 solid-organ transplant recipients (4031 renal, 522 liver). Of the tuberculosis cases, 50 (33.8%) were pulmonary, 21 (14.2%) were pulmonary and extrapulmonary, 13 (8.8%) were miliary, 27 (18.2%) were disseminated, and 37 (25.0%) were extra pulmonary tuberculosis cases involving a maximum of 2 organs. There were 19 cases (12.8%) of graft lost. Of the patients with tuberculosis, 34 (19.9%) died resulting from either tuberculosis or other reasons. Conclusions: In this meta-analysis, most of the centers did not perform pretransplant risk evaluations; every center had different clinical procedures and follow-ups. Tuberculosis prevalence in solid-organ transplant recipients differs according to study population. Case reports were mostly about extrapulmonary tuberculosis. All such patients should be followed-up by a standard regimen during pretransplant and posttransplant periods. Prospective studies should be considered.Item How Did The Battlefield At Gallipoli Become A Tourist Site? Epic Tourism(2022) Okumus, Fevzi; Eser, Zeliha; Koseoglu, Mehmet Ali???Thanatourism??? refers to the management and organization of activities by people who visit death sites. This concept, however, does not sufficiently explain the management and organization of activities for people who want to see and feel the history of victories and epics won by their ancestors to secure the future for coming generations. This study introduces a new approach that includes people motivated to visit death sites for epic-focused tourism by analyzing the hundreds of thousands of Turks who visit Gallipoli every year.Item In the shadow of gender: Wives of prisoners in Turkey(2022) Bekiroglu, Seval; Attepe Ozden, Seda; Icagasioglu Coban, Arzu; 0000-0003-0712-6653Imprisonment of men can many negative economic, social and psychological effects on prisoners, their spouses and children. It is important to evaluate these and understand the gender-related experiences of wives of prisoners. So, we conducted three focus group discussions (FGDs) with 14 women in Turkey. We used an inductive content analysis approach and identified four relevant themes as follows: (1) women's roles (as spouse, mother and social beings), (2) poverty, (3) stigma and exclusion, and (4) coping mechanisms. We noted that our respondents faced economic problems, difficulties in raising children, social exclusion, and emotional difficulties. In Turkey, gender norms and insufficient policies and services for such women exacerbate such issues. It is therefore important to develop gender-sensitive services that would empower and support them.Item An analysis of Turkey's solar PV auction scheme: What can Turkey learn from Brazil and South Africa?(2021) Sirin, Selahattin Murat; Sevindik, IremAs global investments continue in renewable energy technologies, investment costs have declined significantly. Meanwhile, many governments have shifted from pre-set renewable support schemes to auction schemes in order to introduce competition in price setting. Turkey has initiated Renewable Energy Resource Zone (RERZ) auctions to promote solar photovoltaic (PV) and wind technologies. We examine the first of these auctions, Solar PV RERZ, which has ambitious targets in terms of increasing solar PV capacity and enhancing domestic competence in solar technologies. Despite the auction being hailed as a success in terms of low prices, we utilize the Levelized Cost of Electricity generation (LCOE) analysis to demonstrate that the project is vulnerable to macroeconomic shocks and financial risks. Model results show that the capacity factor is the most prominent factor in costs, and 10% change in the capacity factor affects the LCOE about the same rate. Investment cost and interest rate are the other major factors affecting the LCOE. Based on these results, we make recommendations by discussing how Turkey can improve its auction design by incorporating some of the elements used by Brazil and South Africa.Item A tale of two hashtags: An examination of moral content of pro- and anti-government tweets in Turkey(2021) Bayrak, Fatih; Alper, Sinan; 0000-0001-6350-6234During the campaign period of the 2018 Presidential Election in Turkey, there was a burst in the number of tweets posted by both pro- and anti-government Twitter users. Both sides started their own hashtags and reached a total of 2 million tweets in only one day. We analyzed the content of 186,554 tweets from two opposing ideological camps to test the predictions of Moral Foundations Theory, which suggests that liberals and conservatives endorse different moral foundations. We scored each side's level of emphasis on different moral foundations using the Turkish Moral Foundations Dictionary and compared the two groups. Results revealed that the supporters of the conservative government in Turkey were more likely to endorse care, loyalty, and authority foundations of morality, as compared to those who oppose the conservative government. In addition, the general moral emphasis was higher in the tweets of the pro-government group. Being one of the first studies investigating the moral content of political tweets in a non-WEIRD context, the current study yields important findings regarding the external validity of the Moral Foundations Theory's predictions in different cultures.Item Identifying Clinical Characteristics of Hypoparathyroidism in Turkey: HIPOPARATURK-NET Study(2021) Degertekin, Ceyla Konca; Yavuz, Dilek Gogas; Pekkolay, Zafer; Saygili, Emre; Ugur, Kader; Koca, Arzu Or; Unubol, Mustafa; Topaloglu, Omercan; Aydogan, Berna Imge; Kutbay, Nilufer Ozdemir; Hekimsoy, Zeliha; Yilmaz, Nusret; Balci, Mustafa Kemal; Tanrikulu, Seher; Unsal, Yasemin Aydogan; Ersoy, Canan; Omma, Tulay; Keskin, Muge; Yalcin, Mehmet Muhittin; Yetkin, Ilhan; Soylu, Hikmet; Karakose, Melia; Yilmaz, Merve; Karakilic, Ersen; Piskinpasa, Hamide; Batman, Adnan; Akbaba, Gulhan; Elbuken, Gulsah; Bahadir, Cigdem Tura; Kilinc, Faruk; Bilginer, Muhammet Cuneyt; Iyidir, Ozlem Turhan; Canturk, Zeynep; Yilmaz, Banu Aktas; Sayiner, Zeynel Abidin; Eroglu, Mustafa; 34495356Hypoparathyroidism is an orphan disease with ill-defined epidemiology that is subject to geographic variability. We conducted this study to assess the demographics, etiologic distribution, treatment patterns and complication frequency of patients with chronic hypoparathyroidism in Turkey. This is a retrospective, cross-sectional database study, with collaboration of 30 endocrinology centers located in 20 cities across seven geographical regions of Turkey. A total of 830 adults (mean age 49.6 +/- 13.5 years; female 81.2%) with hypoparathyroidism (mean duration 9.7 +/- 9.0 years) were included in the final analysis. Hypoparathyroidism was predominantly surgery-induced (n = 686, 82.6%). The insulting surgeries was carried out mostly due to benign causes in postsurgical group (SG) (n = 504, 73.5%) while patients in nonsurgical group (NSG) was most frequently classified as idiopathic (n = 103, 71.5%). The treatment was highly dependent on calcium salts (n = 771, 92.9%), calcitriol (n = 786, 94.7%) and to a lower extent cholecalciferol use (n = 635, 76.5%) while the rate of parathyroid hormone (n = 2, 0.2%) use was low. Serum calcium levels were most frequently kept in the normal range (sCa 8.5-10.5 mg/dL, n = 383, 46.1%) which might be higher than desired for this patient group. NSG had a lower mean plasma PTH concentration (6.42 +/- 5.53 vs. 9.09 +/- 7.08 ng/l, p < 0.0001), higher daily intake of elementary calcium (2038 +/- 1214 vs. 1846 +/- 1355 mg/day, p = 0.0193) and calcitriol (0.78 +/- 0.39 vs. 0.69 +/- 0.38 mcg/day, p = 0.0057), a higher rate of chronic renal disease (9.7% vs. 3.6%, p = 0.0017), epilepsy (6.3% vs. 1.6%, p = 0.0009), intracranial calcifications (11.8% vs. 7.3%, p < 0.0001) and cataracts (22.2% vs. 13.7%, p = 0.0096) compared to SG. In conclusion, postsurgical hypoparathyroidism is the dominant etiology of hypoparathyroidism in Turkey while the nonsurgical patients have a higher disease burden with greater need for medications and increased risk of complications than the postsurgical patients.Item Dabigatran for Stroke Prevention in Real Life in a Sample of Population from Turkey: D-SPIRIT Registry(2021) Altin, Cihan; 34881702Objective: The D-SPIRIT registry is designed to investigate the safety and effectiveness of dabigatran etexilate in patients with atrial fibrillation in routine clinical practice. Methods: D-SPIRIT is the first national, multicenter, prospective, observational, postmarketing registry that investigates the usage of dabigatran in real life. A total of 326 noveloral anticoagulant-eligible patients with atrial fibrillation who have been taking dabigatran etexilate therapy for stroke prevention at least 6 months from 9 different centers were enrolled into the registry. Patients were followed up for 2 years to evaluate the effectiveness and safety of the treatment. All adverse clinical events including bleeding, thromboembolic events, stroke, systemic embolism, transient ischemic attack, myocardial infarction, and all-cause death were recorded. Results: The mean age was 71.1 +/- 9.6 years, and 57.4% of the study participants were female. The mean CHA(2)DS(2)-VASc (congestive heart failure, hypertension, age >= 75 years, diabetes mellitus, stroke or transient ischemic attack [TIA], vascular disease, age 65-74 years, sex category) score was 3.4 +/- 1.6. The cumulative adverse clinical events rate was 6.30% per year. The rate for embolic events including TIA, ischemic stroke, and peripheral embolism was 1.26% per year. The rate for major bleeding was 2.20% per year, and the mortality rate was 0.94% per year. Conclusion: This registry obtained an important overview of the current safety and effectiveness of the dabigatran etexilate in Turkey. Our results indicate similar rates of thromboembolic and bleeding events with pivotal phase 3 trial and other real-life registries. However, rate of undertreatment usage of dabigatran etexilate in real life was found to be considerable.
