In this paper, thermally-stable, biocompatible and flexible luminescent films with self-healing capability were prepared by combining graphene quantum dots (GQDs) and silk fibroin (SF). Two methods were carried out to combine GQDs and SF: one is to feed silkworms with a GQDs diet and collect their cocoons; the other is to mix GQDs with SF solution directly. Then feeding GQDs/SF composite film and GQDs/SF mixing films of different mass ratios were prepared by natural air drying. The morphology, structure and performance of the SF films were characterized in detail. Results showed that the mixing composite films are flexible, luminescent and thermally stable. The more GQDs in the film, the stronger the luminescence is, in our case. The mixing films exhibit different light color under different excitations, the same with GQDs. However, fed GQDs in the silkworm seem to be playing a quenching effect on SF. It also showed that no new chemical bonds were formed between GQDs and SF, and the two were physically mixed, either by feeding or direct solution mixing. In addition, this fluorescent film also has the particular ability of self-healing by a drop of water. This new biocompatible film may have broad applications in fields of flexible display, biosensing, drug delivery and tissue engineering.
The ‘non-speaking narrator’ as a methodological tool of analysis for various practices of discourse
Authors: Koçak Can
Published: April 2020

This article proposes the ‘non-speaking narrator’ as a methodological tool of analysis and writing with reference to the film Persona, directed by Ingmar Bergman. Focusing on the dialectic between the two characters of the film, the article brings forward the idea that the narrative is relayed by the constant silence of one of the characters. Since the nature of that silence changes the extent of the lingual content, it leads the talking character into divulgence. The ‘non-speaking narrator’ thus brings forward silence as a way of being heard, suggesting a new perspective also to everyday life conventions in communication. This power of the non-speaking narrator as a methodological tool derived from practice has the potential to generate multiple interpretations and can be applied to various areas of communication studies.
How to approach collecting music on streaming services
Authors: Sesigür Onur
Published: April 2020

Consumption, collection and curation activities on streaming music services are a relatively new phenomenon that has not yet been offered an abundance of ways to be approached. This article addresses the information nature of a song and the collection and curation practices on a streaming platform to propose a methodological approach at the intersection of personal information management (PIM) and collection studies. By discussing the state of ownership and experience on streaming, this methodological approach uses the concept of mediality to redefine the collectible as information and decentralizes it by putting the emphasis on the act of collecting. By viewing streaming songs as collectable information objects and focusing on the interaction and experience a listener has with the songs and the environment of the songs, an outline of how a streaming music collection can be studied is provided. The concepts of bookmark for the streaming song and address book for the personal streaming playlist are proposed to study streaming music consumption, collection and curation at the intersection of PIM and collection studies.
Negotiating boundaries in a hybrid climate: The story of a trans-disciplinary documentary film research
Authors: Uygun Zeynep Merve
Published: April 2020

How can one apply trans-disciplinary methods to a practice-based research? The article addresses this question through a self-reflexive piece on a transdisciplinary documentary film presented as a Ph.D. research. The research focuses on the summer holiday practices of veiled women in Turkey to explore the triangular relationship between bodies, spaces and practices. The author argues that a trans-disciplinary research requires a multimethodological approach and demonstrates how documentary film analysis, fieldwork, participant observation, interviews, ethnographic filmmaking and documentary film practice can be applied together methodologically. Additionally, the article explores how artistic methods and narratives are used by the researcher to visually represent veiled women. Concepts such as negotiating through boundaries, third space and hybridity constitutes the recurring themes of the article.
Measuring freedom: Rethinking ranking methodologies
Authors: Tunç Aslı
Published: April 2020

This article is a critical analysis of the methodology of press freedom indices of two independent international watchdog organizations, Freedom House (https://freedomhouse.org/) and Reporters Without Borders (RSF-
https://rsf.org/en). The author argues that press freedom indices tend to offer us a homogenous view of mass media, which facilitates comparisons between countries by masking significant differences and discusses the challenges of dealing with the difference in the conceptualization of media freedom. As a social scientist, she also brings validity and reliability issues, which are crucial in quantitative research methods, into the discussion.

In the last decade following the technological and commercial advances in digital image production and in artificial intelligence, human vision-centred understanding of visuality has changed profoundly. Machine vision technologies (MVTs) are used across a wide spectrum of activities ranging from surveillance to medical diagnosis, to adaptive visual filters on social media. This commentary calls for a rethinking of visuality that takes both technological advances and lessons learned from cultural studies into consideration.
A lion in a matchbox: Artistic identity and cracking the professional code in American higher education
Authors: Funk Clayton
Published: April 2020

This article is an analysis of the culture of academic professionalism of art programmes in American universities. In the Gilded Age, American universities underwent significant reforms that transformed them in to centres for professional education in Medicine, Law, social work, and other professions, including the visual arts. College art was transformed during these years. Guided by theory set forth by Burton Bledstein, the article decodes this new culture with concepts of time spent in practice and training, the specialized spaces (for art this meant studios and classrooms), and words (the discourse, terminology and language that distinguishes professionals from their clientele). These concepts help embody a collective professional identity of people with boundaries to regulate the social experience art faculty and students in a new, and at times troubled modern culture of professionalism.
Artist as teacher and model
Authors: Yeager Raymond
Published: April 2020

Being an artist is often an enigma to art students. They need a model who will demonstrate a way to navigate the world as an artist. We are that model. As art educators, we can help demystify the practice of being an artist and help our students understand it by offering ourselves as models and mentors. In this undertaking, we should be open with students about our own odysseys as artists. Especially the many failures and hardships we faced and overcame to succeed. This modelling of art practice is a form of ‘lending consciousness'. Developed by Russian psychologist Lev Vygotsky, this concept asserts the idea that development is a social or communal process as well as a pedagogical one. By creating a learning environment where we model, as well as instruct, we alter the traditional role we play in the classroom. When our teaching and art-making become intertwined, the students benefit greatly from a more engaged instructor, and it is more likely that they will see themselves as artists-in-training.
An urban walk as a teaching strategy and investigative instrument in art education
Authors: Genet-Verney Rafaèle , Marín-Viadel Ricardo , Fernández-Morillas Antonio
Published: April 2020

This article explores interactions among three topics: the city, visual arts and education, all interconnected through an urban and artistic practice of walking. This reflection is carried out in three fields of thought: education, investigation and artistic creation. On an educative level, one questions how a path through the city can be a strategy for art education learning. In the research field, thanks to analysis of artistic and urbanism methodologies applied to the city, research is carried out using walking maps as tools of art and urban planning investigation. On an artistic level, aesthetic results are desired from the investigation as a result of teaching practice designed to be a creative reflection on the city. We analysed current tendencies in art education through the use of the walking path around the city and investigation using maps. We present the three educative experiences validating the use of urban walks as pedagogic strategies and instruments of investigation.

Authors: Elkomy Ashraf , Aboubakr Mohamed
Published: April 2020

The present study was designed to assess the comparative bio-equivalence of Lincopharm 800Â® and LincoyosrÂ® in healthy broiler chicken after oral administration of both products in a dose of 20 mg lincomycin base/kg b.wt. Twenty four broiler chickens were divided into two groups. The first group was designed to study the pharmacokinetics of Lincopharm 800Â®, while the 2nd group was designed to study the pharmacokinetics of LincoyosrÂ®. Each broiler chicken in both groups was orally administered with 20 mg lincomycin base/kg b.wt. Blood samples were obtained from the wing vein and collected immediately before and at 0.08, 0.16, 0.25, 0.5, 1, 2, 4, 8, 12 and 24 hours after a single oral administration. The disposition kinetics of Lincopharm 800Â® and LincoyosrÂ® following oral administration of 20 mg lincomycin base /kg b.wt, revealed that the maximum blood concentration of lincomycin [Cmax] were 4.81 and 4.62 Î¼g/ml and attained at [tmax] of 1.36 and 1.35 hours, respectively. In conclusion: LincoyosrÂ® is bioequivalent to Lincopharm 800Â® since the ratios of Cmax, AUC0-24 and AUC0-âˆž (T/R) was 0.96, 0.92 and 0.91 respectively. These are within the bioequivalence acceptance range. LincoyosrÂ® and Lincopharm 800Â® are therefore bioequivalent and interchangeable.Â Â Â

Authors: Ashkar Fatemeh , Rezaei Shahla , Salahshoornezhad Sara , Vahid Farhad , Gholamalizadeh Maryam , Dahka Samaneh Mirzaei , Doaei Saeid
Published: April 2020

Background

Polycystic Ovary Syndrome (PCOS) is one of the most common endocrine abnormalities in women. Due to the side effects of drugs, the tendency to use natural antioxidants and anti-inflammatory agents to regulate metabolism, hyperinsulinemia, and hyperlipidemia in PCOS patients has been increased. This review aimed to investigate the role of herbal substances on the treatment of PCOS.

Methods

The present review was carried out using keywords such as polycystic ovary syndrome and/or PCOS and/or herb. Databases including Web of Science, PubMed, and Science Direct were used to collect all related articles published from 1990 to 2019. We excluded studies unrelated to the PCOS and medical herbs.

Results

Overall, 361 records were identified through database searching. After primary screening and the full-texts assessment, 323 records were excluded, and 38 articles were finally included. The results indicate that some medicinal herbs may have a key role in treating PCOS. The compounds in these medical herbs can affect lipid profiles (Aloe vera, chamomile, and cinnamon), insulin resistance (cinnamon, chamomile,Aloe vera, andCamellia sinensis), blood glucose (Aloe vera, cinnamon, andCamellia sinensis), hormones (Aloe vera, silymarin, chamomile, fenugreek,Camellia sinensis,Heracleum persicum,Potentilla,Mentha spicata,Foeniculum vulgar, licorice, andMarrubium), and ovarian tissue (Aloe vera, chamomile,Camellia sinensis,Mentha spicata, and silymarin).

Conclusion

Natural substances such asAloe vera, cinnamon, green tea, fenugreek, and silymarin can be used as a new supportive care for PCOS. Further clinical trials are warranted to confirm their benefits and safety.
Professorinnen und Professoren in der akademischen Selbstverwaltung. Eine Rekonstruktion handlungsleitender Orientierungsrahmen
Authors: Philipps Axel , Johannsen Johanna
Published: April 2020

Zu den zentralen Aufgaben einer Professur an deutschen Universitäten gehört neben Forschung und Lehre die Beteiligung an der akademischen Selbstverwaltung, wobei sich die Hochschulforschung vor allem auf die ersten beiden Berufsfelder konzentriert. Die wenigen Erkenntnisse zum Engagement in der Selbstverwaltung beziehen sich vorrangig auf veränderte organisationale Aspekte. Dieser Beitrag zeigt, wie mit Hilfe der praxeologischen Wissenssoziologie untersucht werden kann, in welchen Orientierungsrahmen das akademische Personal innerhalb der akademischen Selbstverwaltung agiert. Dazu wurden teilnarrative Interviews durchgeführt und mit der dokumentarischen Methode ausgewertet. Im Ergebnis unterscheiden wir zwischen den „Hochschulmanagenden“, „Zurückhaltenden“ und „Pflichtbewussten“, wobei insbesondere der Orientierungsrahmen der „Pflichtbewussten“ erklärt, warum sich Professorinnen und Professoren wiederkehrend in der akademischen Selbstverwaltung gewissenhaft engagieren, obwohl sie der Forschung und Lehre den Vorrang einräumen.

Published: April 2020

Objective

A small thigh circumference is associated with an increased risk of diabetes, cardiovascular diseases, and total mortality. The purpose of this study was to evaluate the association between thigh circumference and hypertension in the middle-aged and elderly population.

Methods

A total of 9520 individuals aged 40 years and older with measurement of thigh circumference were available for analysis. The measurement of thigh circumference was performed directly below the gluteal fold of the thigh. The association of thigh circumference with hypertension was tested in logistic regression analyses and reported as odds ratio (OR) with 95% CI.

Results

Thigh circumference was negatively correlated with systolic blood pressure, diastolic blood pressure, fasting glucose, and total cholesterol. Compared with the lowest thigh circumference tertile group, the risk of hypertension was significantly lower in the highest tertile group, both in overweight individuals (OR 0.68; 95% CI 0.59–0.79, P < 0.001) and obese individuals (OR 0.51; 95% CI 0.38–0.70, P < 0.001).

Conclusion

In the present study, large thigh circumference is associated with lower risk of hypertension in overweight and obese Chinese individuals.

P granules are phase-separated liquid droplets that play important roles in the maintenance of germ cell fate in Caenorhabditis elegans. Both the localization and formation of P granules are highly dynamic, but mechanisms that regulate such processes remain poorly understood. Here, we show evidence that the VASA-like germline RNA helicase GLH-1 couples distinct steps of its ATPase hydrolysis cycle to control the formation and disassembly of P granules. In addition, we found that the phenylalanine-glycine-glycine repeats in GLH-1 promote its localization at the perinucleus. Proteomic analyses of the GLH-1 complex with a GLH-1 mutation that interferes with P granule disassembly revealed transient interactions of GLH-1 with several Argonautes and RNA-binding proteins. Finally, we found that defects in recruiting the P granule component PRG-1 to perinuclear foci in the adult germline correlate with the fertility defects observed in various GLH-1 mutants. Together, our results highlight the versatile roles of an RNA helicase in controlling the formation of liquid droplets in space and time.

Published: April 2020

Hydrothermal system research using Self Potential (SP) Method, 2-D DC Resistivity and surface temperature, has been done at Domas Crater (1700 masl). Potential anomaly which is associated with subsurface structure is obtained by SP measurement, whereas temperature measurement is done to get information about surface temperature distribution laterally and resistivity distribution of volcano structures is known by 2-D DC Resistivity measurement. Hydrothermal activities, which cause the existence of SP value, are modeled using this scheme modeling. This schema modeling is validated by comparing the value of SP model with field measurement. The shallow hydrothermal activities at Domas Crater are influenced by meteoric and subsurface water. The velocity of hydrothermal activities are about 10-9 - 10-7 m/s. 16.64% root mean square error is obtained by Comsol modeling, whereas 6.54% root mean square error is obtained by modeling using finite element method.

Turistlerin istek ve beklentilerinin sürekli değişmekte olduğu bir dünyada işletmeler faaliyetlerini sürdürmektedirler. Turistlerin değişen taleplerine cevap verebilecek otel işletmeleri arasında da rekabet gün geçtikçe artmaktadır. Çevresel şartların sürekli değiştiği bir ortamda otel işletmelerinin rekabet edebilirliklerini arttırıcı bir yöntem olarak da yenilik uygulamaları görülmektedir. Bu çalışmanın amacı, turist yenilikçiliğinin yenilikçi otel tercihine etkisini incelemektir. Bu amaçla, araştırma otel işletmelerinin sundukları hizmetlerden faydalanmış 666 turist üzerinde gerçekleştirilmiştir. Verilerin analizinde betimsel istatistikler, faktör analizi, basit ve çok değişkenli regresyon analizlerinden yararlanılmıştır. Elde edilen analiz sonuçlarına göre, çalışmaya katılanların çoğunluğu sorgulayıcı kategorisinde olup, bunu sırasıyla; öncü, kuşkucu, yenilikçi ve gelenekçi kategorilerinin takip ettiği görülmüştür. Araştırmanın hipotezlerinden biri olan, turist yenilikçiliğinin yenilikçi otel tercihini anlamlı ve pozitif yönde etkilediği tespit edilmiştir. Turist yenilikçiliğinin alt boyutlarından fikir önderliği boyutunun da yenilikçi otel tercihini anlamlı ve pozitif yönde etkilediği yapılan analiz sonucunda görülmüştür. Elde edilen bulgular, otel işletmelerinin başarılı faaliyetler yürütebilmesinin, turistlerin yenilikçilik eğilimine göre yenilik uygulamalarına ağırlık vermesine bağlı olduğunu ortaya koymuştur.
Fred McGraw Donner’in İslâm Tarihçiliği ve İnananlar Hareketi Tezi Üzerine
Authors: ÇOLAK Yaşar
Published: April 2020

Bu makale, Fred M. Donner’in VII. yüzyılda İslâmî hareketin doğuşu ve yayılmasına ilişkin tezi ile Batı ilim dünyasında buna yöneltilen eleştirileri ele almaktadır. Konuya giriş bağlamında Donner’in akademik hayatı, çalışmaları, metodolojisi ve başarısı hakkında kısaca bilgi verilmekte, bilahare İnananlar Hareketi adını verdiği tezi ve hareketin tarihsel bağlamda hızla genişlemesinin dinamiklerine ilişkin görüşleri ortaya konulmaktadır. Donner’in temel tezi şudur: Hz. Muhammed (SAV.) dinî bir lider olarak İslâm’ı benimseyen putperest geçmişli insanların yanı sıra Yahudi ve Hristiyanları da içine alan monoteist ve ekümenik karakterli dinî bir hareket başlatmıştır. Ona göre hareketin başlangıçtaki amacı ayrı bir inanç topluluğu oluşturmak değil, dindar yaşam biçimine dayalı tevhit akidesini ihya etmekti. İnananlar Hareketi yaklaşık yüz yıl sonra, Emevî Halifesi Abdülmelik b. Mervân döneminde, Yahudiler ve Hristiyanları dışlayarak, Müslüman toplum olarak bildiğimiz tek ve ayrı bir inanç grubu hâline dönüşmüştür. Makalenin ilerleyen kısımlarında Donner’in tezine yönelik Batı’daki reaksiyonlara temas edilmekte, son olarak da eleştirel tahlillere yer verilmektedir

Türkiye Ekonomisinin İktisadi Büyüme Hızı Öngörüleri
Authors: ÖNALAN GÖKHAN ORUÇ
Published: April 2020

İktisat bilimi günümüzden yakın bir zaman öncesine kadar beklentileri dikkate almayan bir tarzı benimsemişti. Ancak elde edilen deneyimler göstermiştir ki iktisadi karar birimi olarak bireylerin iktisadi, sosyal ve siyasi beklentileri ekonomi politikası geliştirme sürecine etki etmektedir. Bu şekilde Türkiye ekonomisinin de karar birimlerinin iktisadi beklentileri üzerinden elde ettiği belirli deneyimler bulunmaktadır. Örneğin 2000’li yıllar öncesinde uygulanan iktisadi politikalar enflasyonu indirme amacına yönelik doğru politikalar olsa da karar birimleri üzerinde yeteri kadar beklenti oluşmamasından dolayı başarılı olamamıştır. Sonuç olarak iktisadi politika kombinasyonunda beklentilerin önemini vurgulamak amacıyla yazılan bu çalışma kapsamında da Türkiye ekonomisinin 2019-2021 dönemine dair yıllık iktisadi büyüme performansı, 1961-2018 dönemini kapsayan yıllık iktisadi büyüme hızları zaman serisi üzerinden ARIMA modeli ile tahmin edilerek, iktisadi karar birimlerinin Türkiye’nin büyüme potansiyelinin gelecek seyri hakkında fikir sahibi olması amaçlanmıştır.
