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 Unsustainable harvest of water frogs in southern Turkey for the European market(2021) Cicek, Kerim; Ayaz, Dincer; Afsar, Murat; Bayrakci, Yusuf; Peksen, Cigdem Akin; Cumhuriyet, Oguzkan; Ismail, Ilhan Bayram; Yenmis, Melodi; Ustundag, Erdal; Tok, Cemal Varol; Bilgin, C. Can; Akcakaya, H. Resit; ABC-7273-2020Frogs have been harvested from the wild for the last 40 years in Turkey. We analysed the population dynamics of Anatolian water frogs (Pelophylax spp.) in the Seyhan and Ceyhan Deltas during 2013-2015. We marked a total of 13,811 individuals during 3 years, estimated population sizes, simulated the dynamics of a harvested population over 50 years, and collated frog harvest and export statistics from the region and for Turkey as a whole. Our capture estimates indicated a population reduction of c. 20% per year, and our population modelling showed that, if overharvesting continues at current rates, the harvested populations will decline rapidly. Simulations with a model of harvested population dynamics resulted in a risk of extinction of > 90% within 50 years, with extinction likely in c. 2032. Our interviews with harvesters revealed their economic dependence on the frog harvest. However, our results also showed that reducing harvest rates would not only ensure the viability of these frog populations but would also provide a source of income that is sustainable in the long term. Our study provides insights into the position of Turkey in the 'extinction domino' line, in which harvest pressure shifts among countries as frog populations are depleted and harvest bans are effected. We recommend that harvesting of wild frogs should be banned during the mating season, hunting and exporting of frogs < 30 g should be banned, and harvesters should be trained on species knowledge and awareness of regulations.Item A test of theory of planned behavior in type II diabetes adherence: The leading role of perceived behavioral control(2021) Dilekler, Ilknur; Dogulu, Canay; Bozo, Ozlem; 0000-0002-5906-3706; C-8140-2014Diabetes mellitus is a health complication that millions of people suffer from all over the world. Type II (non-insulin dependent) diabetes requires many changes in the daily lives of patients, including monitoring blood glucose, following a healthy diet, exercising, and taking medications. Although it is vital for their health, patients generally find it difficult to adhere to their medical regimen. In order to better understand the adherence behaviors of type II diabetes patients, the theory of planned behavior (TPB) was used as the theoretical framework for this study. Ninety type II diabetes patients, who were outpatients of four different hospitals in Ankara, Turkey were administered the TPB tool. The mediation analyses provided support for the mediating role of intention for the attitudes-behavior and subjective norms-behavior relations. The findings did not reveal a mediating role of intention for the PBC-behavior relation but a significant direct effect of PBC on adherence behavior was found. Overall, it seems important that PBC and the multi-faceted nature of adherence behaviors are considered when designing interventions for type II diabetes patients.Item Extremely low mitochondrial DNA diversity in a near threatened species, the Cinereous Vulture Aegypius monachus in Turkey(2019) Cakmak, Emel; Peksen, Cigdem Akin; Kirazli, Cihangir; Yamac, Elif; Bilgin, C.Can; ABC-7273-2020The Cinereous Vulture Aegypius monachus is a near threatened raptor that occurs in isolated populations across its range. The only comprehensive genetic study performed so far excluded samples from Turkey, although this area forms a significant part of the species' range. In this study, we used 311 bp long sequences of the mitochondrial cytochrome b gene from 58 Turkish individuals to assess genetic diversity and phylogeny, and to determine if any signals for population expansion exist. Our phylogenetic analyses indicate that the Turkish birds hold, along with those from the Caucasus, an intermediate position between European (Balkan and Iberian) and North Asian (Mongolian) lineages. Our findings also demonstrate extremely low mitochondrial diversity and suggest no population expansion. Despite the low genetic diversity found in this study, other mtDNA gene regions and other nuclear markers should be evaluated together with the current results, before any kind of conservation action plan of this species is applied.
