Using ultraviolet dermoscopy in diagnosing scabies
No full textThe latest generation ultraviolet (UV) dermatoscopes, which emit UV light at a wavelength of 365 nm and enlarge lesions, are practical devices that can facilitate the diagnosis and follow-up of some dermatological diseases with fluorescence that can be observed in skin lesions. In 305 patients, 468 tunnels were evaluated: first in polarized mode and later in UV mode. The recorded samples were compared one-to-one by the same dermatologist. Due to the study's design, images were examined in three stages: tunnel borders, tunnel content and mite appearance. In UV mode, the entire body of mites gives a bright reflex along with an oval-shaped diagnostic clue well beyond the delta sign. The borders of the tunnel reflect brightly in UV mode, with borders that are more sharply visible than in polarized mode. Although the tunnel content cannot be clearly distinguished in polarized mode, especially in people with hyperkeratotic palms, or 'working hands' (e.g. farmers, mechanics and construction workers), with the bright reflex, the tunnel borders in UV mode give a bright reflection and provide a clear view of tunnels. Tunnel content gives a bright reflection in UV mode. Our results show that UV dermatoscopes provide more effective and clearer images than polarized dermatoscopes in the diagnosis of scabies
Seramik Yüzeylerde Lazerle Desen Oluşturma Tekniği Ve Uygulamalar
No full textSeramik Yüzeylerde Lazerle Desen Oluşturma Tekniği ve Uygulamalar by Ceyda Sıkı is an innovative study that examines the impact of technology on the creative process in art and design, specifically focusing on laser technology. The book reveals the new possibilities that computer-aided design (CAD) and manufacturing (CAM) methods, particularly CO2 gas laser machines, offer for ceramic surfaces. This work aims to demonstrate the potential of lasers for creating patterns on unglazed ceramic surfaces in both design and artistic applications. The author emphasises that, unlike traditional decorating methods, lasers can transfer high-resolution vector- or pixel-based graphics with complex geometries onto even relief (textured) surfaces. The applications section details this technique. Forms made from casting slip were treated with various metal oxides (iron, cobalt, etc.) and then subjected to laser thermal processing, resulting in different colour tones. Furthermore, artistic applications were carried out using recyclable terracotta facade panels, addressing a contemporary social theme: "migration policies". The study provides a comprehensive overview of the aesthetic and technical contributions of this innovative method to the field of ceramics, evaluating the advantages of laser technology (speed, flexibility, precision) and its disadvantages (cost, inability to work on glazed surfaces, 3D form limitations)Ceyda Sıkı tarafından kaleme alınan Seramik Yüzeylerde Lazerle Desen Oluşturma Tekniği ve Uygulamalar , sanat ve tasarım alanlarında teknolojinin yaratıcı sürece etkisini lazer teknolojisi özelinde inceleyen yenilikçi bir çalışmadır. Kitap, bilgisayar destekli tasarım (CAD) ve üretim (CAM) yöntemlerinin , özellikle de CO2 gaz lazer makinelerinin, seramik yüzeylerde nasıl yeni imkanlar sunduğunu ortaya koymaktadır. Bu çalışma, lazerin sırsız seramik yüzeylerde desen oluşturma potansiyelini hem tasarım hem de sanatsal uygulama alanlarında göstermeyi amaçlamaktadır. Yazar, geleneksel dekorlama yöntemlerinin aksine, lazerin yüksek çözünürlüklü vektörel veya piksel tabanlı grafikleri karmaşık geometrilerle , hatta rölyefli (kabartmalı) yüzeylere bile aktarabildiğini vurgulamaktadır. Kitabın uygulama bölümünde bu teknik detaylıca ele alınır. Döküm çamurundan üretilmiş formlar üzerine çeşitli metal oksitler (demir, kobalt vb.) uygulanarak lazerle ısıl işlem yapılmış ve farklı renk tonları elde edilmiştir. Ayrıca, geri dönüştürülebilir terracotta cephe kaplama panelleri kullanılarak, "göç politikaları" gibi güncel bir sosyal tema üzerine sanatsal uygulamalar gerçekleştirilmiştir. Çalışma, lazer teknolojisinin avantajlarını (hız, esneklik, hassasiyet) ve dezavantajlarını (maliyet, sırlı yüzeylerde çalışamama, 3D form kısıtlamaları) değerlendirerek, bu yenilikçi yöntemin seramik alanına sunduğu estetik ve teknik katkıları kapsamlı bir şekilde sunmaktadır
Investigating the mediating role of corporate reputation on the relationship between corporate social responsibility and multiple stakeholder outcomes
No full textArıkan, Esra (Dogus Author), Kantur, Deniz (Dogus Author), Maden, Ceyda (Dogus Author), Telci, Emine Eser (Dogus Author)In today’s highly volatile environment, companies strive to leverage the perceptions of their multiple stakeholders more than ever before with the aim to build a sustainable competitive advantage. Accordingly, corporate social responsibility and corporate reputation concepts are of vital importance for both academicians and practitioners, concerning their potential impact on internal and external stakeholders. Recognizing the intensified significance of a multi-stakeholder perspective, the current study attempts to contribute to the literature through examining the mediating role of corporate reputation on the relationship between corporate social responsibility and various outcomes of customers, employees, and investors as the key stakeholders. Based on a reputational ranking of companies conducted by a national magazine since 2001, nine companies were selected from service and manufacturing industries and an online questionnaire was conducted to a multi-stakeholder sample consisting of customers, employees and investors. The results showed that corporate reputation fully mediates the relationship between corporate social responsibility and organizational commitment, employee satisfaction, investor loyalty, purchase intention, and intention to seek employment. On the other hand, there existed partial mediation on the relationship between corporate social responsibility and customer perceived value, customer satisfaction, customer loyalty, customer switching cost, customer commitment, turnover intention, intention to invest, and intention to spread word-of-mouth. The results have important implications for practitioners who seek to manage their relationships with multiple stakeholders through their engagement in corporate social responsibility activities and efforts to enhance their companies’ reputational status
Job resources, engagement, and proactivity: a moderated mediation model
No full textMADEN EYIUSTA, CEYDA/0000-0002-6505-8698Purpose - The purpose of this paper is to investigate the mediating impact of work engagement on the relationship between three developmental job resources (i.e. autonomy, task variety, and feedback) and proactive work behaviors. It also attempted to explore the moderating role of job fit (demands-abilities (D-A) fit and needs-supplies (N-S) fit) in the proposed model. Design/methodology/approach - Data were collected from 225 employees in 20 small and medium-size enterprises in Istanbul, Turkey. Hypotheses were tested using hierarchical multiple regressions and hierarchical moderated regressions. Findings - It was found that engagement mediated the relationships between job autonomy, task variety, and proactive behaviors. Results also revealed that the relationships between autonomy, task variety, and engagement were positive and significant only for the employees with low D-A fit while the positive impact of engagement on proactive behaviors existed only for those employees with high N-S fit. The conditional indirect impact of job resources on proactive behaviors was strongest when the D-A fit was low and the N-S fit was high while this effect was non-significant when the D-A fit was high and the N-S fit was (either) low or high. Research limitations/implications - The generalizability of the findings is limited. Moreover, as the data are cross-sectional, it is not possible to derive causal inferences about the hypothesized relationships. Practical implications-Organizations should provide their employees with more autonomy and task variety to enhance their engagement and proactivity. Moreover, organizations need to consider their employees' level of job fit when they provide certain job resources. Originality/value - This study tests the mediating role of engagement on the relationships between three developmental job resources and proactive behaviors. It also sheds light on the moderating role of job fit in the proposed mediation model.Istanbul Kemerburgaz University Research and Publications Commission [PB014-2013]The author gratefully acknowledges the research support from the Istanbul Kemerburgaz University Research and Publications Commission (Grant No. PB014-2013).

Spatial Injustice
No full textSpatial (in)justice is characterised as the geography of social (in)justice. The city is a network of ecologies composed of infrastructure, economic ideologies, and wealth. The inequalities that emerge as a by-product of these systems highlight the injustices in London evolving from social, economic and spatial patterns in the form of gentrification. This research positions the London metropolis as a demonstration of political power structures. Derived as a result of neoliberal policies implemented since the late seventies and thus becoming a driver of social class inequality. The relationship between architecture and socio-spatial conditions will be addressed in this research and effect, an architectural intervention will be proposed as a solution for gentrification.Architecture, Urbanism and Building Sciences | Architectural Design Crossover
