Clinical and sociodemographic differences in adult women and men with obsessive-compulsive disorder
(Yerküre Tanıtım & Yayıncılık Hizmetleri A.Ş., 2024) Çoban, Deniz Adnan; Tan, Oğuz; Gündoğmuş, İbrahim
Objective: Gender is related to differences in the prevalences, manifestations and comorbidities of mental disorders. Findings on the effect of sex on adults with obsessive-compulsive disorder (OCD) are limited and inconsistent. We aimed to compare male and females with OCD in a large sample of adults. Methods: We included 559 patients with OCD (299 females, 50.68%). We employed the Yale-Brown Obsession and Compulsion Scale (Y-BOCS), Hamilton Depression Rating Scale-17 (HDRS-17) and Beck Anxiety Inventory (BAI). We gathered data about the onset of illness, the years of education, marital status, long-term unemployment, history of hospitalization and suicide attempts, lifetime attention deficit and hyperactivity disorder (ADHD), tic disorder, alcohol use disorder (AUD), substance use disorder (SUD), smoking and symptom dimensions. Results: The Y-BOCS, HDRS-17 and BAI scores were significantly higher in women. Men were characterized by earlier onset of OCD, younger age, longer years of education, higher prevalence of past or current tic disorders and higher frequency of AUD/SUD and smoking. Ratio of being married was higher among women whereas most of males were never-married. History of suicide attempt was more common among women. Conclusion: Our research offers additional support for variations in clinical characteristics of OCD based on gender. It is essential to investigate the biological foundation of gender differences on OCD.
Diurnal variation of essential oil ratio and composition of some basil genotypes
(BANGLADESH BOTANICAL SOC, 2022) Aygün, Yusuf Ziya; Eren, Yılmaz; Ertekin, Esra Nermin
The change of essential oil ratios and components of five different basil genotypes harvested at different times (00:00, 06:00, 12:00, 18:00) in day was investigated. Plants were grown under the field conditions and essential oils of the plants were extracted by hydro-distillation method. Identification of essential oil components were performed by GC-MS. It was the G5 genotype that had the highest essential oil content in all plant parts, regardless of the time of day. The highest essential oil content (2.8%) was obtained from the dry leaves of the G5 genotype from the sampling made at 18:00. The main components of essential oils were determined as linalool, eucalyptol, trans alpha-bergamotene, methyl cinnamate, alpha-muurolol and eugenol. However, while the ratios of these components differed between genotypes, the changes in time of day were similar for some components. Linalool content tended to increase mostly in the middle of the day. This study indicated that essential oil ratio and components of different basil genotypes significantly differed according to harvesting times in day.
Utilization of pumice of Burdur region and zeolite of Bigadic-Balikesir region as fine aggregate in construction materials
(MADEN TETKIK VE ARAMA GENEL MUDURLUGU-MTA, 2020) Beycan Tatanoğlu, Özge; Koçkal, Niyazi Uğur
Volcanic originated pumice and zeolite aggregates have low density owing to their considerable porous structure. Porosity is usually correlated with insulation properties. In order to examine the effects of this lightweight aggregates on dead load of structure and insulation properties of standard construction materials, samples were produced by using pumice and zeolite at varying percentages by volume and control samples were manufactured with crushed sand. The samples were exposed to normal (standard) curing, hot water curing and steam curing to observe the effect of different curing regimes on their behavior. Bulk density and thermal conductivity tests were carried out on samples. Both bulk density and thermal conductivity values of the lightweight mortar samples were smaller than those of control sample. Besides, chemical compositions of aggregates and cement, analyses were also performed. Silica content of pumice and zeolite were %54,09 and %75,14 by mass respectively.
Production of a design developed for the assembly filter parts, optimization of welding and field test
(ASSOC MECHANICAL ENGINEERS TECHNICIANS SLOVENIA, 2022) Maden, Hakan; Çetinkaya, Kerim
For the joining of non-removable plastic parts, methods such as friction welding, friction-stir welding, ultra-sonic welding, chemical joining, and hot-plate welding are used. Rotary friction welding is generally used for joining the filter parts of water treatment devices. After the rotating friction welding of the filter parts, semi-melted agglomerations are formed in the inner parts. To prevent semi-melted accumulation, a weld joint profile design was developed in the ABAQUS software in a previous study. In this study, injection moulds had been produced according to weld joint profile design. The taken plastic presses were welded with the friction welding machine and the joint was controlled and compared. It is seen that the semi-melted agglomeration was successfully confined. By performing Taguchi experimental method and ANOVA analysis on friction welding machine parameters, the optimum pressure conditions were determined in order to carry out static and dynamic tests according to NSF standards and field tests by producing 1500 pilot products, and it has been put into use. The lifetime of the developed filter depends on the material which was used in the manufacture. The next study is aimed to improve the lifetime of the developed filters.
A new family of Lerch-type zeta functions interpolating a certain class of higher-order Apostol-type numbers and Apostol-type polynomials
(NATL INQUIRY SERVICES CENTRE PTY LTD, 2019) Küçükoğlu, İrem; Şimşek, Yılmaz; Srivastava, H. M.
The aim of this paper is to investigate some classes of higher-order Apostol-type numbers and Apostol-type polynomials. We construct Lerch-type zeta functions which interpolate these numbers and polynomials at negative integers. Moreover, by combining some well-known identities such as the Chu-Vandermonde identity with the Lerch-type zeta functions and generating functions for the higher- order Apostol-type numbers and Apostol-type polynomials, we derive some relations and identities including functional equation for these Lerch-type zeta functions with other zeta type functions, Raabe-type multiplication formula for the higher-order Apostol-type polynomials and the Stirling numbers. Finally, we give some remarks and observations on Lerch-type zeta functions and their functional equations.
Incendies in the context of cinematic dialectics and hybrid narrative
(ANKARA UNIV, FAC COMMUNICATION, 2022) Topçu, Çiçek
This study offers a multilevel reading of Denis Villeneuve's film Incendies (2010) through the lens of its filmic framework and a deconstruction and reassembling of the film itself. It begins by using the film to provide a dia-lectical explanation of the main lines and intellectual features of the First, Second, and Third Cinema movements, which succeeded one another but are essentially mutually exclusive. It then connects the features of the film with the narrative features of each of these movements to arrive at a holistic and multi-perspective account of the film. Through a qualitative assessment of which of the film's features are associated with each of these differ-ent movements, the study concludes that the film Incendies has a hybrid structure that erodes the boundaries between different conventions. While underlining the conservatism of the narrative patterns of these three mutu-ally independent cinematic movements, Incendies nevertheless brings them together in way that highlights their dialectic harmony.
Happiness, job stress, job dedication and perceived organizational support: a mediating model
(EMERALD GROUP PUBLISHING LTD, 2023) Akgündüz, Yılmaz; Bardakoğlu, Övünç; Kızılcalıoğlu, Gaye
Purpose - Based on The Conservation of Resources Theory (COR), Spillover Theory and Social Exchange Theory (SET), this study investigates the mediating role of job dedication in the relationships between job stress, happiness and perceived organizational support (POS). Design/methodology/approach - Data were collected from 5-star resort hotel employees in Turkey. 362 valid questionnaires were collected. The research hypotheses were tested using Covariance-Based Structural Equation Modeling (CB-SEM). Findings - The analysis results show that POS is positively related to employee happiness and job dedication. Job stress is negatively related to employee happiness but positively related to job dedication. Job dedication partially mediates the relationships between job stress and happiness, and POS and happiness. Research limitations/implications - The study's findings could be used by hotel managers to improve employees' job dedication, which will lead to increased employee happiness. Together with qualitative and quantitative research methods, future research could be conducted on the predecessors of job dedication and comparatively on employee happiness for different country samples. Practical implications - In order to increase employee happiness, Turkish hotel managers may want to increase POS and decrease perceived job stress of their employees. Although it was found out in this study that job stress increases job dedication, it is also accepted that this unexpected situation arises due to special conditions. Therefore, by reducing job stress, hotel managers may prefer to increase the job dedication of their employees and their happiness indirectly. Originality/value - The current study contributes to the hospitality management literature by investigating the organizational factors behind employee happiness. In addition, it also explored in depth the mediating effect of job dedication on the relationships between POS, job stress and happiness.
Aestheticizing the downfall of industrial capitalism: Jim Jarmusch's tale of intellectual vampires in zombies' world
(UNIV PITTSBURGH, UNIV LIBRARY SYSTEM, 2017) Pehlivan, Bahar Muratoğlu; Atalay, Gül Esra
This study aims to read Jim Jarmusch's movie Only Lovers Left Alive from the perspective of downfall of industrial capitalism and ecosocialist approach. The movie mainly takes place in Detroit Michigan, which is a symbol of the collapse of Fordism and industrialization. Ecosocialist critique of industrial capitalism has common notions with Jarmusch's tale. Thus, theoretical framework of this study has been established on ecosocialist paradigm. In the movie, Jarmusch represents vampires as intellectuals with a wide accumulation of culture and knowledge and places his critique of industrialization from their point of view. Multimodal Discourse Analysis was applied to the movie to find out how the movie did use visual and literal signifiers to establish its narrative.

PurposeThis study aimed to explore the adaptations and perspectives of hotel managers regarding green and smart hotel technologies within the context of sustainability.Design/methodology/approachA comprehensive literature review guided the formulation of this study, followed by face-to-face, semi-structured interviews with hotel managers. A total of 17 prepared questions were finalized after examination by two expert academicians. The responses were analyzed using qualitative research methodology and the results were weighted using the step-wise weight assessment ratio analysis (SWARA) method.FindingsInterviews with sustainability and operational managers yielded insights into environmentally friendly practices and strategies such as reducing energy and water consumption, waste and chemical reduction, supporting local entrepreneurs and adopting smart technologies. These factors are crucial in eco-friendly hotels. According to the SWARA analysis, 'reducing energy consumption' is the most effective criterion.Research limitations/implicationsThis study offers insights into green and smart hotel management by focusing on the perspectives of hotel managers with a small sample. In future studies, research with larger samples on customer perspectives and the effect of hotel selection is recommended.Practical implicationsThis study offers insights to hotel managers on energy conservation and customer satisfaction enhancement through green and technological applications. These technological applications can improve hotel service quality and provide personalized experiences, fostering customer loyalty.Originality/valueThis pioneering study focuses on the intersection of green and smart practices in hospitality. By intertwining the often separately discussed concepts of green and smart, this study presents a novel approach to the sustainability practices in the hospitality industry, holding a key position, especially in Turkey. Implementing these concepts can yield environmental and economic benefits, offering invaluable insights to hotel managers and policymakers into integrating smart technologies with sustainability.
Xanthos West Agora III: dynastic nele
(KOC UNIV SUNA & INAN KIRAC RES CTR MEDITERRANEAN CIVILIZATIONS-AKMED, 2023) Dönmez, Aytaç; Erdoğan, Halil Mert
New evidence obtained from excavation of the West Agora of Xanthos indicates that the first functional formation of the area may have taken place around 530-480 BC. This happened just after the founding of the Xanthos Dynasty during the time of the Dynast Kheziga (Kossika) or his son Kuprlli (Kybernis). Our comparisons with the agora of Avsar Tepesi, dated to the Early Classical period, revealed that these areas were a Lycian design. Epigraphic and archaeological evidence suggest that ceremonies for the purpose of ancestor cult, victory celebrations, and worshiping the gods occurred here. In addition, comparisons are made between our results and Oreshko's pairing of acropolis nele, reveals that these two places, called agora and acropolis in Greek inscriptions from the late fifth century BC, may have been identified nele by the Lycians as only one area. It follows that these areas called nele have quite different characteristics from the Greek agora. Therefore, it shows that Lycian nele were only termed agora in translations on the Inscribed Pillar Monument and the Kudalije Sarcophagus. This occurred because of the lack of a more accurate and appropriate synonym for nele in ancient Greek. In addition, considering the early existence of the cult area of agora gods worshiped in the nele, whose sacred and religious function was a priority, it was initially created under the influence of Anatolian culture. However, due to the significant influence of Athens in the Classical period, it became paired with the Greek twelve gods.
Intimate politics: strategies and practices of female Mukhtars in Turkey
(ROUTLEDGE JOURNALS, TAYLOR & FRANCIS LTD, 2018) Yıldırım, Senem; Uçaray-Mangıtlı, Burcu; Tas, Hakkı
The dualistic separation between the public and private assumes natural and stable boundaries between these spheres. However, a perspective that relies on binaries may deprive certain groups, practices and processes associated with specific spheres from diverse experiences. For instance, women wanting to move from the private sphere and join the political public could not do that due to the domesticated nature of their roles and responsibilities. However, those who do manage to become agents of political activity do so by developing strategies and practices that are context specific. This article examines how the boundaries between the public and private are traversed in Turkish local politics through the mentioned context-specific experiences. It identifies the ways in which female mukhtars in Turkey engage in politics through practices of intimization as a political strategy, which accounts for the strategies and practices of degendering and regendering. The analysis of data from interviews with 20 randomly selected female mukhtars reveals that female mukhtars successfully navigate a versatile strategy of degendering and regendering. In this regard, they may highlight career-defined and gender-neutral attributes or valorize the masculine imperatives of the public domain. They may also affirm and assert their feminine qualities depending on the context.
Automated diagnosis of Alzheimer's Disease using OCT and OCTA: a systematic review
(IEEE-INST ELECTRICAL ELECTRONICS ENGINEERS INC, 2024) Turkan, Yasemin; Boray Tek, F.; Arpaci, Fatih; Arslan, Ozan; Toslak, Devrim; Bulut, Mehmet; Yaman, Aylin
Retinal optical coherence tomography (OCT) and optical coherence tomography angiography (OCTA) have emerged as promising, non-invasive, and cost-effective modalities for the early diagnosis of Alzheimer's disease (AD). However, a comprehensive review of automated deep learning techniques for diagnosing AD or mild cognitive impairment (MCI) using OCT/OCTA data is lacking. We addressed this gap by conducting a systematic review using the Preferred Reporting Items for Systematic Review and Meta-Analysis (PRISMA) guidelines. We systematically searched databases, including Scopus, PubMed, and Web of Science, and identified 16 important studies from an initial set of 4006 references. We then analyzed these studies through a structured framework, focusing on the key aspects of deep learning workflows for AD/MCI diagnosis using OCT-OCTA. This included dataset curation, model training, and validation methodologies. Our findings indicate a shift towards employing end-to-end deep learning models to directly analyze OCT/OCTA images in diagnosing AD/MCI, moving away from traditional machine learning approaches. However, we identified inconsistencies in the data collection methods across studies, leading to varied outcomes. We emphasize the need for longitudinal studies on early AD and MCI diagnosis, along with further research on interpretability tools to enhance model accuracy and reliability for clinical translation.
Global land grab and the Balkans: Continuity and changes in a unique historical context
(ROUTLEDGE JOURNALS, TAYLOR & FRANCIS LTD, 2018) Mandacı, Nazif; Tutan, Mehmet Ufuk
Current developments concerning land grabs in the Balkans suggest that the region is re-experiencing in the post-socialist era what happened in the seventeenth and eighteenth centuries due to the decline of the Ottoman land tenure system, under identical conditions involving fundamental socio-political transformations and integration with global capitalism. These changes are emblematic of a transfer of common to individual ownership. Nowadays, small landholders in some parts of the regionmainly the former labourers on socialist agricultural cooperativesare influenced by the accelerating trend of (re)concentrating landownership, which in some cases takes the form of land grabbing similar to that seen in Africa. This study examines the historical continuity between the Ottoman rule over fledgling nation-states and the post-socialist era by referring to widely discussed socio-economic and political developments regarding contemporary land grab processes.
Some approximations with hurwitz zeta function
(UNIV NIS, FAC SCI MATH, 2020) Aygüneş, Aykut Ahmet
In this paper, we focus on some approximations with Hurwitz zeta function. By using these approximations, we present some asymptotic formulae related to Hurwitz zeta function. As an application, we give two corollaries related to Bernoulli polynomials.
A note on polylogarithms and incomplete gamma function
(UNIV BELGRADE, FAC ELECTRICAL ENGINEERING, 2020) Aygüneş, Aykut Ahmet
In this paper, we firstly introduce the polylogarithms and incomplete gamma function. Then, we claim that there is a relation between polylogarithms and a generalization of incomplete gamma function. Secondly, we give a formula related to polylogarithms. Also,we obtain a relation between incomplete gamma function and the derivatives of polylogarithms. Finally, we find a generating function for the values of incomplete gamma function.

Let me make mathematics and music together: A meta-analysis of the causal role of music interventions on mathematics achievement
(ROUTLEDGE JOURNALS, TAYLOR & FRANCIS LTD, 2023) Akın, Ayça
This research aims to conduct a fixed-effects meta-analysis to unpack the causal role of music interventions on mathematics achievement. Findings indicated that music interventions had a small to moderate positive effect on mathematics achievement (N = 77,595, k = 245, g = 0.36, p < 0.01, 95% CI [0.34, 0.38]). Mathematics skills, instructional mathematical content, types of music interventions, and age were significant moderators, whereas development status was not a significant moderator for this meta-analysis. The most crucial result was that studies using music-mathematics integrated intervention produced a large effect size. This study can be considered interesting in terms of revealing that a significantly strong and positive transfer in mathematics learning was only achieved when used mathematics and music together in the learning environment. Consequently, the current research is regarded to have laid some groundwork for further meta-analytic investigations as it provides detailed, up-to-date, and useful evidence on this issue.
The effects of job satisfaction and meaning of work on employee creativity: An investigation of EXPO 2016 exhibition employees
(INST TOURISM, 2018) Akgündüz, Yılmaz; Kızılcalıoğlu, Gaye; Şanlı, Sabahat Ceylin
Ensuring customer satisfaction is essential for success in the service sector. To satisfy customers, employees should respond rapidly to their demands and display creative behaviours. This empirical study investigates the effect of job satisfaction and meaning of work on employee creativity for employees working at EXPO 2016 in Antalya, Turkey, through a questionnaire survey. The 266 completed questionnaires were analysed by hierarchical regression. It was found that both intrinsic job satisfaction (skill and opportunity) and meaning of work effect employee creativity directly. Recommendations are made to organization managers to benefit from employee creativity, particularly those working in facilities with an intense customer-employee relationship.
Priority based vehicle routing for agile blood transportation between donor / client sites
(IEEE, 2017) Karakoç, Mehmet; Günay, Melih
In this paper, we study Vehicle Routing Problem (VRP) for Blood Transporters (BTs) and propose an efficient vehicle routing scheme for blood transportation between hospitals or Donor/Client Sites (DCSs) within a region that is based on Artificial Intelligence. It is assumed that each BT in a fleet of vehicles starts and completes its route at a blood-bank while visiting a subset of DCSs using the shortest path. However, unlike traditional logistic planning, blood transportation may be time critical. Therefore, in our approach, the vehicle routing is formulated to take into account the urgency of the requests and responses. Consequently, the objective of this study is to minimize the number of BTs while maintaining their minimum traveling lengths considering priority. In this regards, we extended the classical Capacitated VRP (CVRP) and reformulated requests to take into account the priority by assigning weight to each request. A hybrid meta-heuristic algorithm including Genetic Algorithms and Local Search is used to simulate transporting blood requests of DCSs. We challenged our approach with symmetrical CVRP instances taken from literature. In this case study, we observed that both the cost and response time are reduced dramatically for emergency.
Essential oil content and components in different purple basil genotypes according to the diurnal changes
(BANGLADESH BOTANICAL SOC, 2023) Türkmen, Musa; Ertekin, Esra Nermin
In the present study the diurnal variations in plant parts of different purple basil genotypes were determined. Three different purple basil genotypes (Arapgir, Piros and Midnight) were used as plant material. Plants were harvested at 06:00, 12:00, 18:00 and 00:00 hrs to determine the diurnal variation within a day at harvesting time. Essential oil ratio among genotypes, harvesting times and parts of plant varied between 0.460.95%, 0.60 to 0.92% and 0.14-1.29%, respectively. Essential oil ratios among the triple interactions were found to range from 0.05 to 2.57%. The major essential oil was linalool in all genotypes. Results showed that the higher essential oil ratio can be obtained from dry flowers of Arapgir genotype harvested at 00:00 and also, Midnight genotype contained higher essential oil content than others.
