Öğe Ontological Security with its Widening and Deepening Boundaries: An Evaluation through a Bibliometric Analysis and Systematic Literature Review Lens(Center for Foreign Policy and Peace Research, İhsan Doğramacı Peace Foundation, 2025) Balkan-Şahin, Sevgi; Çetiner, ÖzgeUsing rigorous bibliometric and systematic methodologies, this article comprehensively reviews academic studies on ontological security. Based on a Web of Science (WoS) retrieved dataset of 163 articles in International Relations and Political Science journals, the article has examined issues such as keywords, authorship, citation networks, and countries through bibliometric analysis. This quantitative analysis revealing the “widening” dimension of ontological security is complemented by a qualitative overview based on a systematic literature review to highlight the “deepening” dimension of ontological security. Together with an assessment of Turkish academia’s contribution to this widening and deepening literature, the article provides a map of ontological security for future studies.Öğe Financial Performance Measurement of Companies in the BIST Sustainability 25 Index with LBWA and MEREC-based CRADIS Methods(Mehmet Akif Ersoy Univ, 2024) Yilmaz Ozekenci, SureyyaFinancial performance refers to the assessment of a firm's capacity to generate profits and manage its financial assets effectively during a specific period of time. This study addresses the evaluation of financial performance of companies in the BIST Sustainability 25 Index using a hybrid MCDM method. For this investigation, nine criteria, namely, acid- test ratio, asset turnover, current ratio, debt ratio, EBITDA, net profit margin, return on equity, stock return and stock turnover are used to determine the financial performance of companies. In this study, the weight of criteria is calculated using both subjective (LBWA) and objective (MEREC) weighting approaches. After the weight of criteria is determined, the financial performance of companies is ranked using the CRADIS method. The results showed that EBITDA and Stock turnover are the most and least important criteria, respectively. According to results obtained from the CRADIS method, Ere & gbreve;li Iron-Steel, Enka construction and Ford Otosan have the highest financial performance, while Vestel, Ar & ccedil;elik and & Ccedil;imsa have the lowest financial performance in the period of 2018 and 2022. Additionally, the robustness and validity of the results are tested by various MCDM methods, namely, ARAS, COPRAS, EDAS, MABAC, MAIRCA, MARCOS, TOPSIS, CoCoSo and MAUT.Öğe Effectiveness of the clock drawing test in differentiating various types of dementia(Cukurova Univ, Fac Medicine, 2021) Yilmaz, Gulcan Gocmez; Ozge, Aynur; Sahin, Mekselina; Kiral, KahramanPurpose: The aim of this study was to investigate the effectiveness of clock-drawing test (CDT) in differentiating dementia types. Materials and Methods: 48 Alzheimer's disease (AD), 68 vascular dementia (VaD) and 13 frontotemporal dementia (FTD) patients were included in the study. Clock drawing test (CDT), mini mental state examination (MMSE) and other neurophysiological tests (back and forward numerical range, calculation test, abstraction test, word memory tests, boston naming test, word list recall and recognition tests) were applied to all patients. The scores of CDT and other neurophysiological tests were compared between the AH, VaD and FTD groups. The relationship between CDT and other neurophysiological tests was evaluated. Results: There was no significant difference in CDT between the dementia groups. MMSE and back numerical range scores were statistically significant among dementia groups. An positive correlation was found especially in AD and VaD patients when MMSE and CDT tests were used together. In addition, a positive correlation was found between CDT and boston naming test for FTD type. Conclusion: CDT is not a unique predictor to determine primary dementia type. However among the neurophysiological test batteries we used in the study, especially the combined use of MMSE and CDT and combined use of CDT with other tests have an important place in dementia differentiation.Öğe Effects of some control methods on Johnson grass and yield components in tomato fiields(Tubitak Scientific & Technological Research Council Turkey, 2023) Üstüner, Tamer; Al Sakran, Muhammad; Üstüner, MenderesJohnson grass is one of the most dangerous and difficult to control weeds. The aim of this study was to determine the effect of different control methods on Johnson grass in tomato fields and to investigate the effect of these methods on the phenological stages and yield indicators of tomatoes. The study was carried out during the 2019 and 2020 seasons. The experiment treatments were as follows: hand hoe, mulch, preemergence herbicide pendimethalin (5 L/ha), postemergence herbicide fluazifop-P-butyl (1 L/ha), and control parcels. The number of flowers, the number of branches, and the length of the plant were determined in tomato. The yield and characteristics of the fruit were calculated and the fruits were analyzed. For Johnson grass, the time for germination, flowering, and seed maturity were determined. Plant height, fresh and dry biomass weight of weed, and rhizomes were also calculated. The results of this experiment showed that the best yield was 64.943 kg/ha in the hand hoe and the fluazifop-P-butyl treatment. The lowest density and fresh biomass of Johnson grass were detected in the fluazifop-P-butyl (217.3 stem/m2, 1009.4 g/m2) and the mulch (251.7 stem/m2, 1355.2 g/m2) treatments, respectively. The highest density and fresh biomass were detected in control parcels (448.8 stem/m2, 3239.2 g/ m2), and in the pendimethalin treatment (334.2 stem/m2, 1956.4 g/m2), respectively. The percentage of lost yield in the control parcels was 90.1%. Hand hoe was found to be the most effective control method against Johnson grass followed by fluazifop-P-butyl, mulch, and pendimethalin.Öğe Evaluation of cardiovascular disease risk factors knowledge level, Framingham score, and cardiac markers in a healthy population(Cukurova Univ, Fac Medicine, 2022) Topuz, Ayse Nur; Bozdemir, NafizPurpose: The iam of this study was to assess the cardiovascular knowledge level of an educated and healthy population and determine how much they transferred it to daily life. In the current study, we first determined Cardiovascular Disease (CVD) Risk Factors Knowledge Level and Framingham score and investigated their relationship between pulse wave velocity (PWV) and laboratory parameters of healthy personal working for Cukurova University. Materials and Methods: The study was conducted via 192 participants who were selected from the study sample among healthy personnel working for Cukurova University. All participants' knowledge level was determined with the Cardiovascular Disease Risk Factors Knowledge Level (CARRF-KL) scale and the 10-year risk for development of CVD determined by the Framingham risk score. PWV was also determined non-invasively by using an arteriography device. Blood samples were collected from all participants. Results: The mean age of all participants was 45.3 +/- 8.0 years (53.6% woman). The mean CARRF-KL score of the participants was found as 20.4 +/- 4.0 and the mean Framingham score was found 6.9 +/- 5.6. The average PWV was found 7.9 +/- 1.5m/sn. In correlation analyses, PWV was well correlated with both the mean CARRF-KL score and Framingham score. Participants who had the highest CARRF-KL score had also the highest Framingham score and PWV Conclusion: Despite the high level of education and knowledge, it is seen that this knowledge is not reflected in daily lives in terms of CVD risk factors. Further studies are needed whether there is a threshold level of CVD knowledge that must be attained for knowledge to influence behavior and risk factor levels. For effective prevention, knowledge should be supported by behavioral counseling interventions.Öğe Hypogonadism Prevalence and Correlation with Aging Male Symptoms and International Index of Erectile Function Scores(Galenos Publ House, 2024) Sahin, Bahadir; Kizilkan, Yalcin; Yildirim, Omer; Sah, Cem; Kazaz, Ilke Onur; Cihan, Ahmet; Duran, BerkanObjective: To detect the prevalence and associated factors of hypogonadism (HG) among men, who were admitted to urology outpatient clinics for reasons other than sexual dysfunction. Materials and Methods: This is a multicentric study designed and conducted by the Turkish Society of Urological Surgery, Andrology Study Group. Male patients between 50 and 75 years of age who were admitted to the urology outpatient clinic for complaints other than sexual dysfunction and whose total testosterone value was measured were included in the study. The correlation between testosterone value and aging male symptoms (AMS) and the international index of erectile function (IIEF) were evaluated. Patient-related factors such as age and comorbidities were also compared between patients with low testosterone values and normal testosterone values. Results: A total of 1021 patients were included in the study. The mean patient age was 69.9 +/- 8.6. The most common complaint was non-neurogenic male lower urinary tract symptoms (52.3%). HG prevalence was 38.5% according to the threshold provided in the European Association of Urology guidelines (<12 nmol/L) There was no statistically significant correlation between HG and AMS or IIEF scores. In our study, the body mass index (BMI) was found to be the most strongly correlated factor with serum testosterone levels (r=-0.183, p<0.001) Subgroup analysis revealed the prevalence of HG as 44.9% in men with BMI >= 30 kg/m(2). Conclusion: Our results suggest that BMI may be a risk factor for HG, and obese patients may require routine assessment of HG, including serum testosterone measurement and application of symptom questionnairesÖğe The Link Between Trade Openness, Economic Growth, Energy Use and Carbon Emissions: Analysis with a Conceptual Model Proposal(Sosyoekonomi Soc, 2024) Oguz, SuzanThis study examines the relationship between trade openness, economic growth, energy consumption and carbon emissions (CO2) with Structural Equation Modelling (SEM) by offering a model proposal. In this context, a path analysis was carried out with SEM using the 2000-2020 period data of 83 developed and developing countries to examine the direct and indirect effects between the variables. The study's findings show that trade openness directly and significantly affects economic growth, energy consumption and CO2. When the indirect effects are examined, it has been determined that economic growth and energy consumption mediate the relationship between trade openness and CO2, and energy consumption mediates the relationship between economic growth and CO2.Öğe Effect of body satisfaction on online impulse purchase behavior of young people(Cukurova Univ, Fac Medicine, 2023) Kale, Mustafa; Sagtas, Saadet; Bir, Yonca; Koc, Ayse Senay; Koc, MuratPurpose: This research aims to determine the effect of body satisfaction on impulse purchase behaviour and, to detect differences in body satisfaction and impulse buying behaviour based on demographic factors.Materials and Methods: The data were collected from 346 university students in different departments at a foundation university in Mersin. The survey method was used and obtained data was analyzed with path analysis, independent samples t-test, and one-way ANOVA.Results: The positive effect of body satisfaction on impulse buying behaviour was found significant. Significant differences in body satisfaction and impulse buying behaviour were investigated by gender and monthly budget. Body satisfaction differs by gender, while impulse buying behaviour by monthly budget. Body satisfaction differs by gender, while impulse buying behaviour to a monthly budget.Conclusion: Online impulse purchase behaviour increases body satisfaction. Body satisfaction is higher among male students, and the purchase behaviour of students with a high monthly budget is also higher than their counterparts.Öğe Observations on the Causes and Effects of Lisbon Earthquake(Beytulhikme Felsefe Cevresi, 2022) Kant, Immanuel; Topuz, Metin; Tuemkaya, Ahmet SelimThe earthquake that took place in Lisbon on November 1, 1755, at-tracted the philosophical interest of many thinkers such as Voltaire, Rousseau and Kant, both in the context of the physical cause of the earthquake and the problem of physical/moral evil (theodicy). Kant, who always keeps the cause of moral and physical evil at the center of his philosophy, presents an examination of the physical causes of the earthquake, which is considered a physical evil in his early writing. He touches superficially on the spiritual influence of evil on humans and its relation to divine grace. But the idea that such discussions should be examined within the limits of reason and experiment, maintains its vitality in this period of Kant. In the second of three articles, Kant this time conveys the information and observations he gathered from many sources. Its purpose is to examine the possible causal connection of physical evil with divine creation in the context of the limits of reason. In the last of his three articles on the Lisbon earthquake, Kant deals with the arguments made after his second article for the possible causes of the earthquake.Öğe Exploring Relations between Pre-Service English Teachers' Psychological and Social Well-Being and their Perceptions of Positive Classroom Environment(Hacettepe Univ, Elt Dept, 2016) Inozu, Julide; Sahinkarakas, SehnazThis paper reports on findings of a research study that sought to investigate the relationship between classroom environment and candidate teachers' social and psychological wellbeing. Dimensions of psychological and social well-being models include constructs such as personal growth, positive relations with others, and social contribution. Such constructs have impacts on teachers' creating a positive classroom environment, which is a predictor of students' academic achievement. Therefore, this study aims at exploring whether and how psychological and social well-being shape candidate teachers' perceptions of positive classroom environment. To address the focus of this study, the data were collected from 157 senior students at the English Language Teaching department through three questionnaires. The questionnaires measured mainly three variables: Participants' perceptions of positive classroom environment and their psychological and social well-being. The relationships between these variables were tested through Structural Equation Model (SEM) using AMOS (22.0). The results of the study revealed some significant relationships between some of the dimensions only, which may indicate that the participant pre-service teachers are expected to promote positive classroom environment in some aspects, but not all. Regarding this, the study provides valuable suggestions to be included in teacher development programs. (c) 2016 EJAL & the Authors.

Annual data of 208 companies exporting in Turkey for the period 2005-2019 were used. Leverage was used as the dependent variable, and export intensity was used as the primary independent variable. In addition, asset structure, cash flow, firm size variables were added as control variables in the study. The current ratio, real effective exchange rate, and real gross domestic product variables are added to test the estimation results of the model. Panel data regression analysis was applied. According to the analysis results, a positive relationship was found between export intensity and leverage, but this relationship is statistically insignificant. A positive and statistically significant association was found between asset structure and firm size and leverage. A negative relationship was found between cash flow and leverage. There is a negative relationship between the current ratio and the leverage and there is a negative relationship between the real effective exchange rate and leverage. Additionally, gross domestic product negatively affects the leverage, but this relationship is statistically insignificant.Öğe Web 2.0 Supported Flipped Learning Model: EFL Students' Perceptions and Motivation(Cukurova Univ, 2021) Girgin, Pinar; Cabaroglu, NeseThis article presents an action research study examining the implementation of flipped classroom model supported with Web 2.0 technology to provide opportunities to use the target language and to motivate learners. Our participants were 12th grade language class students who were learning English as foreign language in a state school in Turkey. Our data came from a variety of sources including pre-and post-treatment questionnaires, teacher journals, lesson evaluation forms, observation tasks, and semi-structured interviews. Our findings revealed that participating students held positive perceptions and a high level of motivation towards the integration of Web 2.0 technology to Flipped Classroom in their English language learning process. Additionally, they reported a number of advantages associated with flipped learning model and Web 2.0 tools such as increased readiness to the lesson, improvement in variety of language and 4C (i.e., critical thinking, creative thinking, communicating and collaborating) skills, fostered teamwork and boosted creativity. In light of our findings, we propose pedagogical implications for EFL practices.Öğe Attitude and behavioral differences regarding their children's social appearance according to the social appearance anxiety levels of the parents(Cukurova Univ, Fac Medicine, 2022) Gumu, Mahmut; Kale, Mustafa; Cakmak, SonerPurpose: The aim of this study was to examine the attitudes and behaviors of parents with high and low social appearance anxiety levels regarding their children's social appearance. Materials and Methods: In this study, a holistic multiple case study, one of the qualitative research methods, was used. The participants of the research are 16 parents who have a child in the preschool period living in Yuregir district of Adana province. The outlier sampling method was used to determine the participants. In the study, Social Appearance Anxiety Scale (SSAS) was used and applied to 100 participants to determine the social appearance anxiety levels of parents. The data obtained were analyzed with the IBM SPSS 25 program, and a total of 16 parents, eight of whom had the highest and the lowest scores, were determined. Interviews were conducted with the parents using the semi-structured interview form created by the researcher. The interviews were made with audio recordings and the audio recordings were converted into texts and the texts were subjected to content analysis. Results: The highest SSAS score in the participant group was 66, the lowest was 24, and the mean score was 35.71 +/- 9.98. The mean age of parents with low SSAS scores is 34.75 +/- 5.57. The mean age of parents with high SSAS scores is 31.62 +/- 2.38. Differences were determined in the opinions of the parents about their children's social appearance, their expectations for their children's bodies, and the ideal child body definitions according to the SSAS score levels of the parents. Parents with high SSAS scores made more definitions of aesthetic appearance. In addition, it was observed that the children of parents with high SSAS scores had incompatible definitions with Body Mass Index (BMI). On the contrary, it was understood that parents with low SSAS scores do not idealize their children's bodies. In the interventions of parents with low and high SSAS scores on their children's social appearance; Differences were also found in physical activities, clothing preferences and physical appearance practices. Conclusion: While parents with low SSAS scores do not idealize their children's body, it is seen that parents with high SSAS scores make definitions regarding aesthetic appearance. In addition, it was observed that the children of parents with high SSAS scores had definitions that were incompatible with BMI. According to study, parents with high SSAS scores interfere more with their children's body appearance. They show more attitudes and behaviors in the form of eating restrictions, encouragement to action, and comparison with their peers.Öğe COVID-19 pandemic and burnout: factors associated with burnout levels among healthcare workers(Cukurova Univ, Fac Medicine, 2023) Cukurova, Nilgun; Ray, Perihan Cam; Uygur, Ayten Bolukbasi; Celik, Gonca GulPurpose: This study investigated the psychosocial and demographic factors influencing burnout levels among healthcare workers during the coronavirus disease 2019 (COVID-19) pandemic.Materials and Methods: A cross-sectional and descriptive study was performed on a total of 418 healthcare workers from Cukurova University Faculty of Medicine, Balcali Hospital in Turkey. While the participants were selected randomly, a personal information form consisting of 33 open-and close-ended questions, Coronavirus Anxiety Scale, the Maslach Burnout Scale and the Beck Burnout were applied.Results: They were 418 healthcare workers aged 19-63 (mean= 35.51 & PLUSMN;9.38), 284 of whom were 61.8% female, 132 (31.7%) of whom were male, and 2 (0.5%) of whom refused to specify their gender. The study found that emotional exhaustion and depersonalization scores were significantly positively correlated with COVID-19 anxiety scores and Beck anxiety scores in healthcare workers, while personal accomplishment scores were significantly negatively correlated with these variables. The study also revealed that COVID-19 anxiety, Beck anxiety, being female, being young, being unmarried, having children, being diagnosed with COVID-19, having a chronic illness, and working more hours per week were all contributing factors to burnout.Conclusion: Both during and after the COVID-19 pandemic, it is very important to provide various forms of psychological support and make arrangements to address factors that can impact the burnout of healthcare professionals.Öğe Association of cancer response styles and alexithymia with posttraumatic growth in breast cancer patients(Kare Publ, 2021) Cakmak, Soner; Cincin, Melisa; Avci, Ufuk KocatepeObjective: Breast cancer (BC) is one of the most common types of cancer seen in women. Many studies have been conducted to examine negative changes observed in patients diagnosed with BC. However, the traumatic experience of a cancer diagnosis can also have positive consequences, including post-traumatic growth (PTG), a positive life change that develops following a stressful experience. This study was an investigation of the relationship between PTG seen in female BC patients, cancer response style, and alexithymia, the inability to recognize and express one's emotions. Method: A total of 89 female patients who were diagnosed with BC and receiving treatment were enrolled in the study. The Mental Adjustment to Cancer scale, the Toronto Alexithymia Scale, and the Posttraumatic Growth Inventory (PGTI) were administered to the participants. Pearson correlation and multiple linear regression analyses and structural equation modeling (SEM) were used to assess the relationships between normally distributed variables. Results: There was a significant, positive relationship between the fighting spirit reaction style and the PTGI total score (r=0.49; p<0.001), and a significant, negative relationship between the helplessness-hopelessness reaction style and the PTGI total score (r=-0.46; p<0.001). Multiple regression analyses revealed that education level (years) was associated with PTG (beta=1.13; t[82]=2.31; p=0.02) (F[6, 82=1.47]; p=0.2; R-2 =0.10), and the subfactors of changes in philosophy of life (CPL) (beta=0.59; t[82]=3.28; p=0.002) and changes in self-perception (CSP) (beta=0.54; t[82]=2.21; p=0.03); and the length of time since diagnosis was associated with CPL (beta=3.91; t[82]=2.37; p=0.02). SEM analysis showed that a fighting spirit response style to cancer partially mediated the relationship between alexithymia and PTG (chi(2) [12, n=89]=14.24; p=0.29; chi(2)/df=1.19; root mean square error of approximation [RMSEA]=0.05; comparative fit index [CFI]=0.99; incremental fit index [IFI]=0.99; normed fit index [NFI]=0.93). The other cancer response styles did not have a mediating effect on the relationship between alexithymia and PTG. Conclusion: Alexithymia is an important consideration in BC patients. Promoting a fighting spirit response in BC patients, and particularly alexithymic patients, could contribute to the development of PTG.Öğe ZORUNLU KARŞILIK ORANLARINDAKİ UYGULAMA DEĞİŞİKLİĞİNİN BIST BANKA ENDEKSİ ÜZERİNDEKİ ETKİSİNİN ANALİZİ(2023) Kandemir, Şenol; Sanli, ElifBu çalışmada Türkiye Cumhuriyet Merkez Bankası (TCMB)’ nın 23.04.2022 tarihinde yapılan 2022-24 sayılı duyurusu ile zorunlu karşılıkların bankaların bilançolarının pasif tarafına uygulanan zorunlu karşılıkların aktif tarafına da uygulanmaya başlanmasının BIST Banka Endeksinde yer alan bankaların pay fiyatlarına etkisi olay çalışması yöntemiyle analiz edilmiştir.

VUCA dünyasında lojistik sektörünün içinde bulunduğu belirsizliğin tetiklenmesinde döviz dalgalanmaları ve pandeminin kilit rol oynadığı belirtilmiştir. Buna paralel olarak, VUCA dünyasında lojistik sektörünün karşılaştığı en önemli sorunlar; müşteri sorunları, sınır kapılarında yaşanan sorunlar, akaryakıt fiyatları, konteyner sorunu ve kuralların sürekli yenilenmesi olarak ifade edilmiştir. Son olarak, lojistik sektöründe belirsizlik yaratan ve anlaşılması en zor (muğlak) durumun ekonomik dalgalanmalardan kaynaklı olduğu belirtilmiştir.Öğe YENİ DÖNEM ANNELİK: EKOLOJİK ANNE OLMA YOLUNDA KADINLARIN DEĞİŞEN TÜKETİM DAVRANIŞLARI(2020) Çabuk, Serap; Erdoğan, Gür DuyguBu çalışma, annelerin aile yaşam döngüsü içerisinde değişen satın alma ve tüketim davranışlarını keşfetmek ve bu süreçte yaşadıkları deneyimlerini ortaya çıkarmak amacıyla yapılmıştır.Bu kapsamda, annelerin çevreci ürünlere karşı bakış açıları, ideal ekolojik anne profili algıları ve ekolojik anne olmaya çalışırken yaşadıkları sıkıntılar incelenmiştir. Araştırma, yüksek eğitim seviyesine sahip, çalışan annelerden oluşan katılımcılar ile derinlemesine görüşmeler ve odak grup görüşmeleri yapılarak gerçekleştirilmiştir. Katılımcı annelerin ekolojik duyarlılığa sahip olmalarına rağmen, satın alma ve tüketim odaklı davranışlarında çevre duyarlılıklarının düşük olabildikleri saptanmış ve bu davranışlarının altındaki sebepler keşfedilmeye çalışılmıştır. Çalışmanın bulgularına göre katılımcı annelerin ekolojik duyarlılıkları paketli gıda kullanmama, çocuklara özel doğal, organik içerikli ürün satın alma, yerli üreticileri tercih etme, kimyasallara ve hijyene karşı yoğun hassasiyet ilevegan ürünlere yönelme olarak ortaya çıkarken, ekolojik anneliğin zorlayıcı tarafları ise ekolojik tüketime dair doğru bilgiye ulaşabilme zorluğu, zaman sıkıntısı, yerli ve doğal üreticilere ulaşma zorluğu ve doğal içerikli ürünlerin yüksek fiyatlandırması olarak ifade edilmiştir. Katılımcılar ideal annelik kavramının göreceli olduğuna dikkat çekerken, 100% ekolojik olma ile ilişkili olmadığını da vurgulamışlardır. Çalışma bulgularının, yeşil tüketici anneleri hedef alan işletmelerin pazarlama faaliyetlerine destek vereceği umulmaktadır.Öğe Yeniden Kullanılabilir Maskeler için Çevre Dostu Tedarikçi Seçimi: Entropi Tabanlı TOPSIS Yöntemi ile Bir Uygulama(2024) Özbek, Hazal Ezgi; Oğuz, SuzanSürdürülebilir ürünlerin kullanımı arttıkça işletmeler için tedarikçi seçimi daha önemli hale gelmektedir. Bu ürünler doğal kaynakların israfını azaltmakta ve çevreye daha az zarar vermektedir. Maske kullanımı ve çevre bilincinin artmasıyla birlikte insanlar maske ve diğer birçok ürünü seçerken çevresel faktörleri dikkate almaya başlamıştır. Bunun sonucunda geleneksel tedarikçi seçim prosedürü yerine çevresel faktörleri dikkate alan çalışmalar literatürde giderek daha çok ilgi görmektedir. Bu çalışmanın amacı, çevre dostu ürünler satan bir işletme için Çok Kriterli Karar Verme (ÇKKV) yöntemleri ile bir maske tedarikçisi seçmektir. Bu doğrultuda ÇKKV yöntemlerinden Entropi tabanlı TOPSIS yöntemi kullanılarak seçim için en uygun çözüme ulaşmak hedeflenmiştir. Seçim yapmak üzere literatürden yola çıkılarak 4 kriter ve bu kriterleri dikkate alan 6 alternatif tedarikçi belirlenmiştir. Öncelikle Entropi yöntemi ile ele alınan kriterler ağırlıklandırılmış daha sonrasında TOPSIS yöntemi kullanılarak maske tedarikçileri arasında sıralama yapılmıştır. Çalışmanın bulguları, ele alınan kriterler arasında en önemli kriterin “Yeniden Kullanılabilirlik” (K1) olduğunu göstermektedir. Sıralama sonrası alternatifler arasında en uygun maske tedarikçisinin ise “Tedarikçi 2” (T2) olduğu sonucuna ulaşılmıştır. Maske tedarikçisi seçim sürecinde bu kriterlerin değerlendirilmesi, işletmelerin daha güvenli, daha verimli ve sürdürülebilir bir tedarik zinciri oluşturmasına yardımcı olmaktadır. Seçim sürecinde daha bilinçli ve doğru kararlar alınması müşteri memnuniyetinin ve işletme itibarının artmasına da katkı sağlamaktadır.Öğe YATIRIM TEŞVİK DUYURULARININ İMALAT ŞİRKETLERİNİN PAY GETİRİLERİNE ETKİSİNİN ANALİZİ(2020) Yakar, Soner; Kandir, Serkan Yılmaz; Elbir, GözdeÇalışmada imalat şirketleri tarafından yapı- lan yatırım teşvik belgesi duyurularının şirketle- rin pay getirileri üzerindeki etkisi araştırılmıştır. Olay çalışması yöntemi uygulanmıştır. Borsa İs- tanbul’da yer alan ve imalat sektöründe faaliyet gösteren 41 şirketin 2012 ve 2020 arasındaki döneme ait yatırım teşvik belgesi alınması ile il- gili 54 adet duyurusu incelenmiştir. Yatırım teşvik belgesi alındığına dair duyuruların yapıldığı gün- ler, olay günleri olarak belirlenmiştir. Olay gün- lerinden beş gün öncesi ve beş gün sonrası olay penceresi olarak seçilmiştir. Çalışma sonuçları, yatırım teşvik belgesi alınması hakkındaki du- yuruların şirketlerin paylarında anormal getiriye neden olduğunu göstermiştir. Borsa İstanbul’un yarı kuvvetli formda etkin olmadığını göster- mektedir. Bu durum ayrıca yatırımcıların, yatırım teşviklerinin pay getirilerinin artıracağı yönünde beklentiye sahip olduğunu gösterebilir.
