Öğe λ-statistical convergence of sequences of functions in intuitionistic fuzzy normed spaces(Hindawi Publishing Corporation, Journal of Function Spaces and Applications, 2012) Karakaya, Vatan; Şimşek, Necip; Ertürk, Müzeyyen; Gürsoy, FaikWe study λ-statistically convergent sequences of functions in intuitionistic fuzzy normed spaces. We define concept of λ-statistical pointwise convergence and λ-statistical uniform convergence in intuitionistic fuzzy normed spaces and we give some basic properties of these concepts.Öğe How do household coping strategies evolve with increased food insecurity? An examination of Nigeria's food price shock of 2015–2018(Wiley, 2024) Quinton, Justin; Jenkins, Glenn P.; Olasehinde‐Williams, GodwinFaced with a significant devaluation of its currency and a surge in food prices, the Nigerian government prohibited the use of foreign currency for food imports. This essentially blocked the importation of numerous food items under the guise of stimulating the domestic output of these staples. Consequently, food prices in Nigeria increased despite a global decline in food prices, and the incidence and severity of food insecurity escalated. This study examines the changes in the types and severity of coping mechanisms for food insecurity resulting from the food price shock caused by the oil price crash, currency devaluation, and restrictions on foreign exchange. Nigeria's General Household Survey Panel data from 2012 and 2015, during periods of high oil prices, is compared with data from 2018 when oil prices had remained low, the currency had been devalued, and the treasury had been depleted. Alongside detailed descriptive statistics, logistic and hurdle regressions are employed for statistical analysis. Findings indicate a rise in the percentage of Nigerian households grappling with food insecurity from 2015 to 2018. During this period, 68.7% of households resorted to at least one coping mechanism, 31.8% adopted six or more coping strategies, and 43.2% resorted to severe coping strategies. The issue stems not primarily from natural disasters or conflicts but from a failure in macroeconomic and agricultural economic policies. Our findings confirm that these policies come at great cost, particularly to female‐headed households, single‐parent households, households headed by elderly people, and other vulnerable populations, pushing them deeper into food insecurity.Öğe Çocuk filmlerinde kaygı ve korku(Edam, 2011) Şentürk, RıdvanÇocuk filmleri birçok açıdan incelenmesi gereken özellikler taşımaktadır. Yapılan araştırma ve analizlerde sıklıkla karşılaşılan konulardan biri de çocuk filmlerinde sergilenen şiddet unsurudur. Ancak şiddet kavramının tam olarak anlaşılabilmesi ve değerlendirebilmesi için, korku ve kaygı gibi temel duyguların çocuk filmlerinde nasıl üretildiği ve biçimlendirildiği sorusunun tartışılması gerekmektedir. Bu bağlamda çocuk filmlerinde korku ve kaygının üretilmesi ve biçimlendirilmesi, çocuk psikolojisi ve eğitimi açısından, şiddete nispetle çok daha önemli, sarsıcı ve kalıcı etkiler uyandırmaktadır. Nitekim korku ve kaygı duyguları, uygulanan şiddetin sadece oluşturduğu psişik bir etki değil, aynı zamanda kendisinden beslendiği ve ifadeye kavuştuğu temel bir kaynaktır. Bu bakımından çocuk filmlerinde yer alan şiddet sahnelerinin derinlemesine irdelenebilmesi için korku ve kaygı duygularının nasıl üretildiği sorusunun özenle analiz edilmesi ve değerlendirilmesi gerekmektedir. Bu bağlamda çalışmada, korku ve kaygı kavramlarının tanımlamaları yapılmakta, günümüzde olu?an korku kültürünün sinemadaki tarihsel izleri sürülerek öncelikle tartışma zemini oluşturulmaktadır. Çalışmada ayrıca ifadeye kavuşan kavramsal tanımlamalardan hareketle seçilen bir çocuk filmi (Harry Potter) örneği incelenerek, korku ve kaygı duygularının üretilmesi ve biçimlendirilmesinde kullanılan ifade teknikleri açığa çıkarılmakta ve değerlendirilmektedir. Değerlendirmenin son bölümünde ayrıca çocukların film ve medya alanında işaret edilen potansiyel tehlikelere karşı korunabilmesi için gerekli olan sorumluk bilincinin oluşması, paylaşılması ve muhtemel önlemlerin gerçekleştirilmesine yönelik önerilere yer verilmiştir.Öğe Aortic arch and intracardiac repair without circulatory arrest in neonates and infants(Baycinar Medical Publishing, 2014) Karacı, Ali Rıza; Şaşmazel, Ahmet; Dedeoğlu, Reyhan; Aydemir, Numan Ali; Harmandar, Buğra; Erdem, Hasan; Cengiz, Dicle; Çelebi, Ahmet; Yekeler, İbrahimBackground: In this article, we aimed to report our surgical experiences with selective antegrade cerebral perfusion combined with the aortic arch and intracardiac surgery in neonates and infants. Methods: Medical data of 27 consecutive patients (18 boys, 9 girls; mean age 9.9+1.7 days; range 1 to 26 days) who undergoing aortic arch and intracardiac repair between March 2007 and April 2012 were retrospectively analyzed. The link between perioperative risk factors and 30-day mortality following surgery were investigated. Results: The mean body weight of patients were 3.2±0.9 kg. Major associated cardiac defects were present in 12 and included truncus arteriosus (Vaan Pragh type 4) (n=2), transposition of the great arteries (n=5), double outlet right ventricle with Taussing Bing anomaly (n=2), and aortopulmonary window defect (n=3). Renal insufficiency and dialysis were statistically significantly associated with mortality [Chi square 27 (p=0.000) and 20.66 (p=0.000), respectively]. Conclusion: Aortic arch repair with simultaneous intracardiac surgical repair can be done with selective antegrade cerebral perfusion at a single stage in neonates and infants.Öğe An important episode in the history of the Ottoman red crescent socienty: The Italo - Turkish war of Tripoli (1911-1912)(Turkish Historical Society, 2017) Macar, Oya DağlarThe War of Tripoli resulted in the Ottoman Empire losing its last territorial possession in North Africa and therefore also its sovereignty in this part of the world. At the same time, the war led to a number of "firsts" in the history of the Ottoman Red Crescent as an institution. With this war, the Red Crescent Society transformed from a temporary into a permanent institution and also began to use the crescent as a permanent symbol. The institution's international "immunity" was used as a cover by a number of volunteering patriotic officers in order to reach the battlefront in secret, and since this was a clear wartime violation, the Ottoman Red Crescent received much criticism. Moreover, the institutional image of the Ottoman Red Crescent Society began to take shape among Muslims both domestically and internationally, thanks to its activities during the War of Tripoli. At the end of the war, according to Italian claims, the crescent was no longer merely a symbol among Muslim Arab tribes, but it stood for the "unity of Islam"; the society was also quite effective when it came to supporting the Turkish officers. Furthermore, the Red Crescent was very effective in its efforts to address the public and draw the world's attention to this war, to which the Ottoman government did not actively send any troops. As a result of these activities, aid was sent from Muslims around the world-from India, Great Britain, Egypt, Bosnia, South Africa, and so on-as well as from various Western countries, in cash and in kind: medical supplies and medicine arrived, together with volunteer doctors, surgeons, and healthcare staff. During the War of Tripoli, the Red Crescent Society also gained its first experiences in working together with foreign Red Cross and Red Crescent committees. This collaboration helped not only with acquiring significant experience with dispensing medical care on the battiefront, but also with recognizing shortcomings in an international context and accepting them. © 2017 Turkish Historical Society.

The main premise underlying the research model is that certain principles in each management model impact the emergence of certain innovativeness types. The issue has especially been dealt with its reflections on high tech companies in technoparks. These companies are known for their entrepreneurial and innovative behaviour. However, as to the authors' knowledge, the impact of their management model on their innovativeness capacity has been an understudied issue. Within this framework, following a thorough literature review, hypotheses have been tested by using data from high tech firms in a university technopark. Findings supported the view that different principles of each model significantly impact different organizational innovativeness dimensions. Detailed analyses also put forth interesting results which will open up new fields for further research in this vein.Öğe Affective temperament profiles of overactive bladder patients reply(Aves, 2016) Sarıbacak, Ali; Altınbaş, Kürşat; Yılmaz, Hasan; Özkan, Alp; Özkan, Levend; Oral, Timuçin[Abstract Not Available]Öğe Biyolojik ritim değerlendirme görüşmesinin Türkçe sürümünün güvenilirliği ve geçerliliği(Cumhuriyet Univ Tip Fak Psikiyatri Anabilim Dali, 2012) Aydemir, Ömer; Akkaya, Cengiz; Altınbaş, Kürşat; Kora, Kaan; Sücülluoğlu Dikici, Didem; Akdeniz, Fatma; Kalaycı, Fatma; Oral, E.

F.In this paper we introduce a new concept for lacunary strong P-convergent with respect to an Orlicz function and examine some properties of the resulting sequence space. We also show that if a sequence is lacunary strong P-convergence with respect to an Orlicz function then it is 8 theta(r,s),-convergent. In addition, lacunary strong P-convergent with respect to an Orlicz function is compared to other summability methods.Öğe Radial basis and LVQ neural network algorithm for real-time fault diagnosis of bottle filling plant(Univ Osijek, Tech Fac, 2014) Demetgül, Mustafa; Yazıcıoğlu, Osman; Kentli, AykutIn this study, an Artificial Neural Network (ANN) is developed to find faults rapidly on a pneumatic system. The data were saved and evaluated considering system is working perfectly and faults are predetermined. These faults include having no bottle, a nonworking cap closing cylinder B, a nonworking bottle cap closing cylinder C, insufficient air pressure, water not filling and low air pressure faults. The signals of six sensors were collected during the entire sequence and the 18 most descriptive features of the data were encoded to present to the ANNs. Two different ANNs were applied for interpretation of the encoded signals. The ANNs tested in the study were learning vector quantization (LVQ) and radial basis network (RBN). The performance of LVQ and RBN was found to be fine with the presented procedures for a system having very repetitive sequential data.Öğe SUPPLIER SELECTION WITH TOPSIS METHOD IN FUZZY ENVIRONMENT: AN APPLICATION IN BANKING SECTOR(Yildiz Technical Univ, 2015) Ayvaz, Berk; Bolturk, Eda; Kactioglu, SibkatEvaluation and selection of the appropriate supplier is complicated and time consuming decision making process for companies. Selection of inappropriate supplier leds to higher cost and it influences negatively business process of companies in competitive environment. In this paper, fuzzy-TOPSIS method, considering combination of quantitative and qualitative evaluation criteria, is presented to select appropriate supplier under uncertain environment. The proposed model is applied to the electronic signature purchasing process of a firm that operates in banking sector in Turkey. Quality, purchasing costs, additional costs (maintenance, training, and update costs etc.), security level, compatibility with existing IT infrastructure, after-sales support, and technical competence are selected for supplier selection process in accordance with a detailed literature review and experts' opinions.Öğe Operators ideals of generalized modular spaces of Cesaro type defined by weighted means(Eudoxus Press, Llc, 2015) Şimşek, Necip; Karakaya, Vatan; Polat, HarunIn this work, we investigate the ideal of all bounded linear operators between any arbitrary Banach spaces whose sequence of approximation numbers belong to the generalized modular spaces of Cesaro type defined by weighted means. Also, we show that the completeness of obtained operator ideals.Öğe Analyzing activation energy and binary chemical reaction effects with artificial intelligence approach in axisymmetric flow of third grade nanofluid subject to soret and dufour effects(Begell House Inc, 2023) Shafiq, Anum; Çolak, Andaç Batur; Sindhu, Tabassum NazThe use of nanotechnology has led to the design of many modern and more cost-effective implementation, such as solar power generation, the redevelopment of heat exchangers, and the modernization of the medical and pharmaceutical industries. In this study, the combined effects of activation energy with binary chemical reactant in a steady magnetohydrodynamic mixed convective third-grade nanofluid flow by radially radiative stretching plate has been analyzed with an artificial intelligence approach. Heat transfer analysis was conducted with heat generation, Joule heating, and Soret and Dufour effects. By incorporating appropriate transformations, the initial nonlinear coupled partial differential equations expressing the fluid model were formed as a comparable nonlinear ordinary differential equations system. Three different artificial neural network models were proposed in order to predict the skin friction, Nusselt number, and Sherwood number values of the fluid model by the Shooting Runge-Kutta Fehlberg 4, technique using the data set created by taking various values of the relevant parameters. It is worthy of noting that the average deviation values for each output parameter remained less than 5%. Furthermore it is also observed that mean square error values for skin friction coefficient, local Nusselt number, and local Sherwood number values were attained as 3.63 x 10(-3), 4.03 x 10(-4), and 8.62 x 10(-3), respectively. The obtained results show that artificial neural networks are an engineering tool that can be used with high accuracy to estimate the combined effects of activation energy and binary chemical reaction in a fixed magnetohydrodynamic mixed convective third-grade nanofluid flow with a radial radiative stretched plate.Öğe On ii>θ -statistical convergence of order α in intuitionistic fuzzy normed spaces(Editura Acad Romane, 2015) Savaş, EkremIn this paper, following a very recent and new approach, we introduce the notions of I -statistical convergence and I-theta -statistical convergence of order alpha, where 0 < alpha <= 1, with respect to the intuitionistic fuzzy norm (mu,nu) and we mainly investigate their relationship, and also make some observations about these classes.Öğe Women and hegemonic masculinity in diplomacy: Changing norms and practices(Uluslararasi Iliskiler Konseyi Dernegi, 2018) Süleymanoğlu Kürüm, Rahime; Rumelili, BaharTraditionally male-dominated, diplomacy has entered into a period of transformation with large numbers of women entering the profession. This article introduces the main contributions of the limited number of studies which analyses diplomacy from a gender perspective, and surveys the prevailing masculine norms in diplomacy through examples from different countries. Subsequently, the article discusses how a similar transformation is underway in Turkish diplomacy. Drawing on published memoirs and interviews of female diplomats, it is found that while masculine norms remain prevalent in Turkish diplomacy, they are also weakening gradually with higher numbers of Turkish female diplomats being promoted to prestigious posts.Öğe Managing gender diversity in Pakistan and Turkey: a historical review(Edward Elgar Publishing Ltd, 2010) Ozbilgin, Mustafa; Syed, Jawad; Dereli, Beliz[Abstract Not Available]Öğe A Simple Attack on a Recently Introduced Hash-Based Secure User Authentication Scheme(Int Journal Computer Science & Network Security-Ijcsns, 2006) Kim, Minho; Koc, Cetin KayaUser authentication is an important service in network security. Recently, several user authentication protocols have been proposed. However, a scheme which withstands all known attacks is not yet available. The Lee-Li-Hwang (LLH) authentication scheme [3] was proposed to circumvent the guessing attack in the Peyravian-Zunic (PZ) password scheme [6]. However, Yoon, Ryu, and Yoo (YRY) [9] discovered that the LLH scheme still suffers from the denial of service attack, and proposed an enhancement for the LLH scheme to solve its security problems. More recently, Ku, Chiang, and Chang (KCC) [2] demonstrated that the YRY scheme is vulnerable to the offline guessing and the stolen-verifier attacks. In this paper, we show that the YRY scheme is also vulnerable to the denial-ofservice attack. Furthermore, it was also claimed in [2] that the YRY scheme cannot achieve backward secrecy. We show in this paper that this claim is not entirely valid.Öğe Certain class harmonic mappings related to starlike functions(Işık Üniversitesi, 2014) Kahramaner, YaseminLet S* be the class of starlike functions and let SH be the class of harmonic mappings in the plane. In this paper we investigate harmonic mapping related to the starlike functions.Öğe A talent management model for today's organizations: The devshirme system(Ankara Hacı Bayram Veli Üniversitesi, 2018) Bayraktar, Osman; Alayoğlu, NihatBu çalışmada öncelikle yetenek yönetimi kavramsal açıdan ele alınmış, daha sonra Osmanlı Devleti yönetiminde insan yetiştirme uygulaması olarak devşirme sisteminin temel öğeleri ve geliştirme sürecinin aşamaları belirlenmiştir.
