The electronic structure of phosphotungstic (H3PW12O40) heteropolyacids modified by Fe2+ cation
Authors: Niemiec Piotr Jan
Published: May 2021

In this paper the influence of substituting the tungsten atom with an iron ion in the primary structure of the phosphotungstic heteropolyacid with the Keggin anion structure was investigated. Characterization of the electronic structure of the modified heteropolyacid was performed using: population analysis according to NBO scheme, total (TDOS) and partial (PDOS) density of states spectra, energy and chemical character of frontier orbitals (HOMO / LUMO) and the size of the HOMO-LUMO band gap. Additionally, the mechanism of interaction between the Fe2+ with H2O molecule, acting as a chemical reaction medium, was investigated. Most cases showed a significant effect of the introduced transition metal ion (Fe2+) on the above-mentioned properties in relation to the nonmodified heteropolyacid H3PW12O40.

Analysis of dentistry cements using FTIR Spectroscopy
Authors: Lada Agata
Published: May 2021

The aim of this study was to evaluate the influence of artificial saliva on dental materials. Dental cements of various compositions and applications were analyzed. Five types of cements were selected for the study: ionomer glass, carboxylic glass and cements used for temporary fillings: zinc-sulphate cement and cement containing calcium hydroxide.
Dental materials were prepared in accordance with the manufacturer's instructions. In the first stage, the cements were examined using the transmission technique in the range of 400-4000 cm-1. Dental cements were incubated in saliva at pH 5 for 21 days. After this time, the FTIR spectra for the cements were measured again and placed in artificial saliva. It was found that the FTIR spectra of dentistry cements after contact with artificial saliva differ from those corresponding to the starting materials.
Spectroscopic analysis was also performed on saliva before and after incubating dental cements and materials used as temporary fillings. FTIR results indicate that under these conditions changes occur on the surface of dental materials due to their incubation in artificial saliva. The composition of saliva changes after the incubation of dental materials in it. Urea present in artificial saliva is degraded. Carbonates and phosphates are formed on the surface of dental materials. The disappearance of some bands in the spectra of the cements and their appearance in the spectra of the artificial saliva indicates the transfer of some components from the cements to the artificial saliva. The environment of the artificial saliva affects the dental materials. Analogous changes in the spectra of all tested dental materials are observed. These changes are limited to their area.

Authors: Ibrahim Ismail Mohammed , Hassan Rania , Mostafa Raham Hasan , Ibrahim Mayada Ahmed
Published: May 2021

Background: Maintaining hemodynamic stability during intracranial surgery is one of the most important tasks. There is no general agreement regarding which anesthetics are optimal for craniotomy. Propofol and short-acting opioids are usually used, but their use is not without side effects. Recently, dexmedetomidine has been considered a safe alternative in different surgeries. Objectives: We aimed to assess the efficacy of 0.5 µg/kg/h dexmedetomidine infusion without loading dose as an adjunct to general anesthesia for craniotomy. Methods: A prospective, randomized, double-blinded, parallel-group, placebo-controlled trial was conducted. Setting: Single university teaching hospital’s operating rooms and postoperative intensive care unit. Patients: A total of 50 patients scheduled for elective supratentorial craniotomy participated in this study. Interventions: Patients were randomly divided into either control group (group C) and Dexmedetomidine group (group D). Main outcome measure: Intraoperative hemodynamics measurements at specific timings. Results: We found that dexmedetomidine had significantly maintained mean arterial blood pressure and heart rate (P-value < 0.001); with lower intraoperative fentanyl and propofol consumption in group D (132 ± 35 µg and 14 ± 30 mg, respectively) when compared to group C (260 ± 38 µg and 534 ± 66 mg, respectively). Finally, a lesser sedation level was noticed in the dexmedetomidine group, together with a significantly lesser recovery time of 10.3 ± 4 min. Conclusions: Dexmedetomidine infusion without loading dose could be an efficacious and safe agent in achieving hemodynamic stability with intraoperative opioid-sparing effect and lesser recovery time.

Published: May 2021

: Hydatid cyst is one of the predominantly cystic liver lesions and is also a zoonotic disease that is highly endemic in the Mediterranean region. This condition has extensive differential diagnoses, such as hepatic mesenchymal hamartoma, a rare benign hepatic tumor, which commonly occurs in infants and children, and is extremely rare in adults. Its imaging findings vary from a cystic tumor to a solid mass occupying one or both lobes of the liver. We report an unusual case of a purely cystic mesenchymal hamartoma of the liver in a 60-year-old female patient. The patient had been treated with albendazole for several years; however, the final histopathology revealed mesenchymal hamartoma.

Authors: Körükcü Melek
Published: May 2021

Social gender is a concept built with life experiences. It distinguishes men and women through their biological differences. Social gender attributes behaviors and roles in accordance with the gender identity of the society to individuals. Social studies regard each student as a unique individual. Social studies students should be sensitive to these differences in their relationships and should respect each other. This is important for respect and equality between the genders. In this context, social studies teachers have an important role in conveying concepts such as gender, equality and human rights to their students accurately and effectively. The aim of this study is to examine social studies teachers’ perceptions of social gender equality in terms of various variables. In the research, qualitative and quantitative methods were used together and mixed structure was applied. The quantitative study group of the research consists of 112 female and 92 male social studies teachers in total. Participants were determined by using criterion sampling, one of the purposeful sampling methods. In the research, the qualitative study group was selected from the quantitative research group through simple random sampling. A total of 20 social studies teachers, 10 female and 10 male, working in 6 different schools were interviewed. In the study, quantitative data were collected with the “Social Gender Perception Scale” developed by Altınova and Duyan (2013). The semi-structured interview form prepared by the researcher was used to obtain qualitative data. The qualitative data of the research were analyzed by content analysis method. The quantitative data obtained in the study were analyzed in IBM SPSS 15.0 program. Social studies teachers’ views on social gender equality have also been evaluated in terms of curriculum literacy. At the end of the study, it was found that social studies teachers have high social gender perceptions. In the gender variable, it was determined that the social gender perception levels of female social studies teachers were higher than male teachers. In the qualitative findings of the study, it was found that teachers treated their students equally and fairly, regardless of gender, and avoided sexist discourse. It was determined that when sexist attitudes and groups were formed in the classroom, teachers directed their students to respect and empathize with each other. In addition, it was found that the teachers mostly explained gender equality in their lessons by linking with biographies. Recommendations are made taking the findings of the study into consideration.

Authors: Karahan Berna Urun
Published: May 2021

Literacy is an important result of language teaching. Language skills are like the pieces of a whole. The accurate acquisition of these skills, which are needed to be used effectively by individuals both in their social and educational life, is equally valuable. Writing is a skill that is acquired and developed mostly during the learning process among these skills. Writing requires not only recognizing the letters and language rules but also understanding and internalizing oneself and the environment. Therefore, emotions, opinions and experiences regarding this skill should be emphasized. The aim of this study is to review the relationship between secondary school students’ writing attitudes and anxieties, and writing dispositions. The study group of the study included secondary school students who were randomly selected in the center of Kars, Turkey in the 2019-2020 academic year. Data were collected using “the Attitude Scale towards Writing for Secondary School Students”, “the Writing Disposition Scale”, and “the Writing Anxiety Scale for secondary school Students”. The results showed that secondary school students’ writing attitudes, dispositions and anxieties did not produce a significant difference based on the variable of gender.

Published: May 2021

Inquiry Based Learning (IBL) is a student-centered strategy within the constructivist learning approach. This strategy is an important approach that makes students active inside and outside the classroom, and enables students to work in groups, conduct research, present their research, and increase their academic success. When the literature is reviewed, there are many studies that show that IBL increases the academic success of students. The aim of this study is to make the meta-analysis of articles and theses carried out in Turkey between the dates of 01.01.2000 and 01.03.2020 that investigate the impact of IBL on the academic achievement. In this study, meta-analysis method was used to determine the effects of IBL on students’ academic achievement based on grade levels and publication types. The studies evaluated within the scope of this study were created by using the databases of Google Scholar and the National Thesis Center of the Council of Higher Education. To this end, 30 studies were selected in accordance with year, method, data, and publication type criteria. In this study, the thesis and article evaluation form developed by the researchers was used as the main means of data collection. Comprehensive Meta-Analysis (CMA) program was used to analyze the data. According to the results of this study, it is concluded that IBL significantly increases the academic achievement and the effect sizes are meaningful when grade levels are compared. That is, IBL at high school level is more effective than other educational levels, and when the effect sizes are examined, there are no significant differences based on the types of publication (i.e., articles and theses).

Equity vs. Ethic Literacy – Socio-Educational Dilemma in the Case of Pandemic Finland, Autumn 2020
Authors: Loima Jyrki
Published: May 2021

This case study aimed to comprehend socio-educational policy in the light of pandemic ethic literacy in Finland. Consequently, methodologically the official, public, and ethic research data were triangulated to analyze the Ministry’s understanding on educational equity in Finland. Discussion involved global pandemic ethic principles (transparency, participation, review and revisability). Hermeneutic methodology revealed imbalances. Ministry of Education and Culture failed regionally, as well as qualitatively, in its quantitative by-the-book policy. As the main finding, pandemic ethics were generally ignored by the Ministry. Ethic principles were not recognized – or were neglected. Furthermore, Ministry’s decision-making was unconditional, instead of being participatory and revising. Lacking transparency was revealed in rhetoric of “several” children, or probable “likelihood”, without argumentation. However, the policy could have been revisable with increasing evidence. Epistemic imbalances and hermeneutic injustice occurred regionally and qualitatively. Those involved all, both the vulnerable, and gifted pupils. Finally, the policy created inequity, adding ageist and racist elements in southern country. Moreover, the Ministry repeatedly acted against its vision. While Ministers, and responsible authorities, should update their “hidden” curriculum, regional policies and Covid-19 variants deserve further studies.

Published: May 2021

Literacy is a term generally used for adults and young people. Basically, it is an acquisition that includes the process of reading, writing and understanding symbols in any language. While this concept, whose definition and scope has expanded over time, refers to people who can only say their names in the past, today it refers to individuals who can perform more functional skills. What is expected from today’s literacy, which is also referred to as functional literacy, is not just saying the name, but also understanding what you read and harmonizing these information with the environment. It is critical to create texts that are easier to interpret, especially for poor readers and individuals learning foreign languages, in today’s world where reading comprehension and correct use of information have become extremely important. In this context, the text simplification method, which is one of the text modification methods, comes to the fore. In accordance with these information, this current study aims to presents the bibliometric analysis of articles on text simplification, which are published in journals indexed in Scopus database in the field of social sciences. The data set of the study consists of 194 articles on text simplification published in journals scanned in the field of social sciences and scopus database. These 194 articles were examined in terms of different variables. The research is generally a descriptive study and document analysis method was used as a method.

Authors: DEMİR Yıldırım
Published: May 2021

Factor analysis is a multivariate statistical method that aims to obtain a small number of new variables by combining many interrelated variables. This study aims to determine which countries are associated with each other in terms
of COVID-19 disease and which country is under which factor with a data set consisting of daily case numbers. Covid-19 data covering 16 countries for 201 days obtained from Github was used as the material in the study. Factor analysis
was performed by applying Principal components and Varimax rotation. With the KMO test, it was determined that the data set was suitable for factor analysis and with the principal component approach, sixteen original variables
were reduced to four factors with a loss of approximately 24%. After the Varimax rotation process, it was determined which variable (country) under which factor. According to the results, the USA (35393.14) is the first and China
(47.64) is the last (sixteenth) in terms of the number of daily cases. As a result, it can be said that countries with similar characteristics in terms of the number of daily cases are under the same factor and therefore, the factors
affecting the virus or the methods of combating the virus in these countries are close to each other. In general, countries in the fourth factor are more successful in combating the virus, and other countries can achieve more successful
results by using similar methods.
The Importance of Participation Banking in Stakeholders Capitalism

Ana akım iktisadın mülkiyet esasına göre temel görüşleri, sermayedarlar kapitalizmi ile devlet kapitalizmi arasındadır. En bilinen ifadesi liberalizm olan sermayedarlar kapitalizmi görüşünde, sermaye sahiplerinin, kendi karlarını maksimize
ederken toplum refahına katkıda bulunacağı varsayılır. Devlet kapitalizminde ise temel olarak sermayenin devlete ait olmasıyla veya onun müdahale etmesiyle, toplum refahını adil bir şekilde sağlayacak düzenin kurulacağı görüşü
savunulur. Fakat şirketlerin, aşırı kar hırsıyla yönettikleri işletmeler, başta iklim krizi olmak üzere çeşitli olumsuzluklara neden olmaktadır. Bunların herkes tarafından görünen birinci şekli, tahrip edilmiş ve doğal yapısı bozulmuş
bir çevre ve küresel ısınma olgusuyla yaşanan doğal felaketlerdir. İkinci önemli olumsuzluk da, aşırı gelir dağılımı adaletsizliklerinin neden olduğu kargaşalar ve iç savaşlar sonucunda gezegenimizde sayısı her geçen gün artan
umutsuz insanlardır. Dolayısıyla her iki uç yaklaşımın iflas ettiği günümüzde, bunun temel sebebi olan şirketlerden ve hissedarlarından daha fazlasını yapması beklenmektedir. Bu beklentinin temel amacı gezegende sürdürülebilir
kalkınmanın, faaliyetlerin yürütülebilmesinin sağlanabilmesidir. Bunun için de tüm tarafları kapsayan paydaşlar kapitalizmi kavramı gündeme gelmiştir. Bu yaklaşım, işletmelerin faaliyetlerini yürütürken taraf olduğu tüm paydaşların
hakkını gözetmelerine işaret etmektedir. Çalışmada, tarafların/paydaşların rollerine değinilerek, yapılması gereken yeni düzenlemelerle, paydaşlar kapitalizminin nasıl gerçekleştirilebileceği verilmeye çalışılacaktır. Özellikle
işletmelerin finansman faaliyetlerinde, katılım bankacılığının geliştirebileceği finansman araçlarıyla ilgili örnekler verilerek bu amaca ulaşmada finansal sistemin önemi, yapabilecekleri de aktarılmaya çalışılacaktır.
As a Source of History the Term "Fi Sebilillah" and Its Historical Frame in the Quran
Authors: ÇAKIRTAŞ Mehmet
Published: May 2021

Hz. Peygamber’in ve ona inanan müminlerin İslamı yaşama ve tebliği uğrunda verdikleri her türlü mücadele, Kur’an-ı Kerim’de “fî sebîlillah” tabiri ile sıfatlandırılmıştır. Diğer temel kaynaklarda olduğu gibi İslam tarihi kaynaklarında
da yaygın bir şekilde kullanılan bu ifade, daha ziyade Müslümanların Müslüman olmayanlarla ilişkilerindeki temel nitelikleri tanımlamıştır. Bu durum siyer kaynaklarına da önemli ölçüde yansımış, ayrıca ilk Müslümanların düşünce
dünyasını etkilemiştir. Bu makalede, siyerin temel kaynaklarından biri olan Kur’an-ı Kerim’den hareketle “fî sebîlillah” kavramının siyerdeki yansımaları araştırılmıştır. “Fî sebîlillah” ifadesi üzerine, özellikle tefsir ve fıkıh
alanında yoğunlaşan çeşitli çalışmalar yapılmıştır. Ancak tespit edilebildiği kadarıyla konu siyer açısından ele alınmamıştır. Araştırmada öncelikle Kur’an’daki “fî sebîlillah” tabirinin yer aldığı ayetler tespit edilmiştir. Tekikler
neticesinde on bir ayrı kavram ve kelimenin, “fî sebîlillah” tabiri ile birlikte kullanıldığı belirlenmiştir. Bu kavram ve kelimelerin dört ana konuya indirgenebileceği anlaşılmış ve bu şekilde başlıklandırılmıştır. Araştırma neticesinde
“fî sebîlillah” tabirinin cihad, gazve ve seriyye gibi savaşa dönük yönlerinin olduğu gibi Müslümanların gayrimüslimlerle ilişkilerine istikamet veren niteliklerinin de olduğu görülmüştür. Bu tabir aynı zamanda Müslümanların davranışlarının
ilkelerini de ortaya koymuştur. Çalışmada, Müslümanların düşmana karşı mali kaynak oluşturmada bir yöntem olarak infakta bulunmalarının “fi sebîlillah” tabiri ile teşvik edildiği görülmüştür. Bu süreçlerdeki her türlü çabanın kıymetini
“fî sebîlillah” tabiri nitelemiştir.
Risk Management in Museums: International Approaches
Authors: ERTÜRK Nevra
Published: May 2021

Müzelerin en temel işlevlerinden birisi korumadır. Tarihsel süreç içinde müzelerin koruma çalışmalarının kapsamı genişlemiş ve 1980’lerin sonundan itibaren müzelerde risk yönetimi konusu gündeme gelmiştir. Farklı sektörlerde uygulanan
risk yönetimi yaklaşımı; kurumların zarar azaltma ve baş edebilme kapasitesini artırmayı hedefleyen bir çalışmadır. II. Dünya Savaşı sonrasında kültür mirası alanında ilk defa UNESCO tarafından kullanılan risk yönetimi kavramı,
sadece müzelerde değil, tarihi çevrelerden anıtlara, arkeolojik alanlardan kütüphane veya arşivlere kadar farklı yaklaşımlarla uygulanmaktadır. Bu bağlamda müzeler koleksiyonları ile ön planda olup, toplumun ve gelişiminin hizmetinde
eserleri toplamakta, korumakta, sergilemekte, araştırma yapmakta ve toplumla iletişim kurmaktadır. Risk yönetimi çalışmalarında, koleksiyonların yanı sıra, müze binası, personel ve ziyaretçi de göz önünde bulundurulmaktadır. Bu
bağlamda uluslararası literatürde müzelere yönelik riskler; fiziksel kuvvet, yangın, su, hırsızlık, hatalı bağıl nem ve sıcaklık değerleri, morötesi ve görünür ışınımlar, kirlilik, biyolojik etkinlik ve ihmal olarak sınıflandırılmaktadır.
21. yüzyılda tüm dünyada ön plana çıkan iklim değişikliği, terör saldırıları ve salgın hastalıklar da müzelere yönelik riskler arasında yer almaktadır. Müzelerde risk yönetimi alanında yoğun bir şekilde çalışan Kanada Konservasyon
Enstitüsü (CCI), Uluslararası Kültür Varlıklarını Koruma ve Restorasyon Çalışmaları Merkezi (ICCROM), Hollanda Kültür Mirası Ajansı (RCE) ve Belgrad’taki Konservasyon Merkez Enstitüsü (CIK) tarafından geliştirilen risk yönetimi
yaklaşımı, risk yönetimi aşamalarının da temelini teşkil etmektedir. Söz konusu aşamalar şunlardır; durum değerlendirmesi, risklerin belirlenmesi, risk analizi, risklerin değerlendirilmesi, uygulama ve izleme. Bu çerçevede makalenin
amacı; risk yönetimi yaklaşımının müzelere uygulanabilirliğini tartışmaktır. Bu amaç çerçevesinde makalenin ana araştırma sorusu: CCI, ICCROM, RCE ve CIK tarafından geliştirilen risk yönetimi yaklaşımı farklı ölçekteki müzeler
için uygulanabilir nitelikte midir? Makalenin kapsamı müzelerde risk yönetimi konusundaki uluslararası tartışmalarla sınırlıdır. Makalede, risk yönetimi kavramının tanımı; uluslararası kurumların müzelerde risk yönetimiyle ilgili
çalışmaları ve yaklaşımları; müzelere yönelik riskler ve risk yönetiminin aşamaları hakkında bilgi verilmektedir. Makalenin sonuç bölümünde, risk yönetimi yaklaşımının müzelerde uygulanabilirliği değerlendirilmekte ve öneriler
sunulmaktadır. Elde edilen bulgulara göre, risk yönetimi yaklaşımı küçük ölçekli müzelerde uygulanabilir niteliktedir. Söz konusu yaklaşımın orta ve büyük ölçekli müzeler için geliştirilmesi gerekmektedir. Risk yönetimi yaklaşımının
doğru bir şekilde uygulanabilmesi için risk yönetimi politikalarının hazırlanmasına; müzelerde risk yönetimi ile ilgili eğitimlerin, tüm ön lisans, lisans ve lisansüstü düzeydeki eğitim müfredatlarında ders olarak yaygınlaştırılmasına
ve bu alanda uzmanların yetiştirilmesine ihtiyaç vardır.

Araştırma konumuzu oluşturan 2b Nolu Kilise’nin de yer aldığı yapı kompleksi, Kapadokya Bölgesi’nde Nevşehir’in Avanos ilçesinin 5 km güneydoğusunda, Zelve Vadisi’nde yer almaktadır. Kuzeyden güneye doğru uzanan vadi; güney, güneydoğu
ve güneybatıya doğru üç kola ayrılmaktadır. Yapı ikinci kolun üzerinde güneye doğru uzanan vadinin doğusunda, üst kotta bulunmaktadır. Zelve Vadisi’nde yaşam 5. yy’da başlamıştır. 7. ve 10. yy’lar arasında, Arap akınlarından dolayı
korunaklı bir yer olan vadide nüfus artmıştır. 11. yüzyılın ikinci yarısından itibaren Türk akınlarıyla birlikte vadide Müslüman ve Hıristiyan nüfus Türk egemenliği altında birlikte yaşamışlardır. 30 Ocak 1923’te imzalanan mübadeleden
dolayı vadideki Hıristiyan nüfus çekilmeye, 1949 yılında vadide oluşan kaya kopması nedeniyle Müslüman nüfus da vadiyi terk etmeye başlamıştır. 1954 yılında vadi tamamen boşaltılmıştır. 1964 yılında ise günümüzdeki Açıkhava müzesine
dönüştürülmüştür. 2b Nolu Kilise, konum olarak hem yapı kompleksinin hem de vadinin geneline hâkimdir. Kilise tek nefli plan tipine sahiptir. Vadide bu yapıyı önemli kılan; içindeki süslemelerin daha az tahribe uğrayarak günümüze
ulaşmasıdır. Bu da hiç şüphesiz girişinin korunaksız ve yüksek bir yerde olmasından kaynaklanmaktadır. Bu çalışmada daha önce yayınlanmamış olan 2b Nolu Kilise’nin de yer aldığı yapı kompleksi bütünüyle ele alınmıştır. Yapı kompleksinin;
mimari özelliklerinin tanıtılarak belgelenmesi, mimari çizimlerinin yapılması ve mevcut durumunun belgelenerek bilim dünyasına tanıtılması amaçlanmıştır.

Sinema 126 yıllık tarihi ile en genç sanat dallarından biri olarak kendi anlatım biçimini ve içeriğini oluşturana kadar kendinden önce gelen diğer sanat dallarından hem içerik hem de biçim bakımından yararlanarak var oluş sürecini
hızlandırmak istemiştir. Elbette bu sinemanın kendine özgü yazım biçimi olan senaryoyu da etkilemiştir. Bu bağlamda senaryo başta tiyatro ve edebiyat olmak üzere film/dizi uyarlamaları; diğer adıyla yeniden çevrimler, biyografiler,
otobiyografiler, çizgi romanlar, bilgisayar oyunları gibi birçok kaynaktan yararlanmış ve bunları sinemaya özgü bir anlatım biçimiyle yeniden yazmıştır. Türk Sineması da Türk edebiyatının önemli eserlerini filme alarak bu akımı
takip etmiş, zaman içinde video oyunları hariç diğer tüm uyarlama türlerini de hayata geçirmiştir. Türk Sineması bu uyarlama türleri içinde özellikle yeniden çevrimler konusunda dünyanın öncü sinemaları arasında yer almaktadır.
Senaryo kaynağa sadakatine göre ise Birebir Uyarlama, Yorumlama ve Esinlenme olmak üzere üçe ayrılır. Bu çalışma uyarlama senaryonun tarihçesini, özelliklerini ve türlerini belirlemek ve detaylı bir şekilde açıklamak amacıyla literatür
tarama yöntemi ile gerçekleştirilmiştir. Bu doğrultuda uyarlama senaryonun tanımı, ilk uyarlamalar, kaynağa sadakatine göre uyarlama çeşitleri ve kaynağına göre uyarlama çeşitleri ele alınmış ve tüm uyarlama türleri örneklerle
açıklanmıştır. Sonuçta elde edilen verilen değerlendirilmiş ve uyarlama senaryonun sorunları tespit edilerek bu sorunların giderilebilmesi için de bazı önerilerde bulunulmuştur.
Myth or Fact? Echo Chambers in Online Political News Consumption
Authors: KUTLU Asuman
Published: May 2021

The dissemination of information through digital media has changed the process of being informed about current political events. Previous research evidence extends in two opposite directions: Digital platforms improve the functioning
of democracy through amplifying of information sources while they may serve as echo chambers allowing people to easily seek out information complementing their opinions, thereby generating political polarization. This study integrating
theories of selective exposure and uses and gratifications seeks to explore selective exposure in digital media and users’ motivations to consume and share information reinforcing their views. The study was approved by the Beykent
University Social and Human Sciences Etthics Committee decision dated 11.01.2021. A maximum variation sample of 20 politically interested individuals explored their political news consumption habits and motivations under conditions
of selective exposure through 5 synchronous online focus groups in a 2-month period. The data was analysed utilizing a thematic approach. Two main themes emerged. (i) Selective exposure to political news and motivations: access
to unbiased political information was identified as the main motivator of selective exposure. Guidance was found to be the key motivator to obtain political information. (ii) Online echo chambers: The vast array of political information
sources may increase online polarization. Respondents’ political news consumption behaviour and attitude towards people holding opposing views may demonstrate the existence of echo chambers along with political bullying.

Çalışan performansı pek çok örgütsel çıktıya neden olan bir kavramdır. Çalışan performansını değerlemek için örgütler tarafından çalışanların sergiledikleri performansların ölçülüp, denetiminin yapılması zorunludur. Bu değerlemenin
amacı, çalışanların yaptıkları faaliyetleri belirleyip, zayıf kaldıkları alanları tanımlamak, sorumluluklarını yerine getirip getirmediklerinin tespitinin yapılması ve işin gerektirdiği şekilde doğru bir akış sergileyip, sergilemediğini
ortaya koymaktır. Gerekli performans sergilemeyen çalışanların uyarılması ya da iş ile ilgili bağlantısının kesilmesi sağlanır. Çalışan performansının ölçülmesinde, çalışanın belirlenen hedeflere ne derece yaklaştığı ve önceki
dönemlerde elde ettiği performanslarının kıyaslanması sonucu oluşan kriterler kullanılır. Çalışanların, çalışma şekli ve davranışları sonucu ortaya çıkan performansın örgütsel amaçlara ulaşmada önemi büyüktür. Hawthorne çalışmalarından
günümüze, çalışan performansının arttırılması ile ilgili çalışmalar yapılmaktadır. Bu çalışmada 2000-2020 yılları arasında “çalışan performansı” konusunda yapılan TR Dizin çalışmaların bibliyometrik analizinin yapılması amaçlanmıştır.
Bibliyometri, dokümanlar ile ilgili süreçlerin ve özelliklerin analiz edilmesini içeren bir araştırma yöntemidir. Türkiye’de gerçekleştirilen bibliyometrik çalışmalarda, lisansüstü tez çalışmalarında genel olarak ulusal tez veri
tabanı kullanılırken, makale türünde ele alınan bibliyometrik çalışmalarda ise dergi incelemesi ya da alan incelemesi yapılmaktadır. Bu çalışmada, çalışan performansı konusunda en çok makale yayınlayan dergiler, çalışmaların yıllara
göre dağılımı, tek bir çalışmaya en çok atıf alan yazarlar ve toplamda en çok atıf alan yazarlar, en çok katkı sunan üniversiteler, bu üniversite yazarlarının üniversitelerine atıf katkıları ve çalışmaların en çok ilişkilendirildiği
diğer değişkeneler tespit edilerek elde edilen sonuçlar raporlanıp, yorumlanmıştır.

Bread is a staple food prepared by baking a dough of flour and water. The virtually infinite combinations of different flours and differing proportions of ingredients has resulted in the wide variety of types, shapes, sizes, and textures available around the world. Considering the worldwide consume of this staple food, this study aimed to develop and assess the chemical and technological characteristics of a new biofortified blend, containing wheat, locust bean flours, iron and folic acid (applied in the form of powder or microcapsules), for the production of bread with nutritional and prophylactic characteristics for human health. Besides bread wheat properties for baking, locust wheat flours was added to the blend in a small amount (0.5%) to increase water absorbance through its polar amino groups of proteins, whereas folic acid and iron inclusion considered the human needs on a daily basis. An 85.89- and 3.93-fold increases for folic acid and iron was carried out through fortification. It was found that, relatively to wheat flour T65, the contents of some minerals (Ca, K, Si), fatty acids (C16:0, C16:1, C18:0, C18:1; C20:1) and sugars (raffinose, sucrose, glucose and fructose) were significantly higher in locust bean flour. Upon blends iron and folic acid fortification, toughness, deformation work / gluten strength and the elasticity index prevailed when powder was used, whereas minimum values were obtained for ash, toughness and gluten strength in the standard blend. Moreover, significant differences were not found for fatty acids. In bread biofortified with folic and iron in the form of powder, all fatty acids (excepting C18:2 and C18:3) prevailed, but lower values were found for sugars and total soluble solids. Moreover, breads height, weight, specific volume remained higher in standard bread, but upon application of benzoic acid or methyl 4-hydroxybenzoate lower shelf life values were found. Although from a hedonic perspective, consumers preferred the standard bread, the biofortified blend revealed a high-quality index suitable for development of a functional staple food incorporating iron and folic acid (in the form of powder or microcapsules). Nevertheless, folic acid as proved to be highly labile during baking, but incorporation of microcapsules slightly limited this degradation. Considering the shelf life of the biofortified bread, pulverization with methyl p-hydroxybenzoate seemed to be the most effective additive.

The objective of this study was to evaluate the economic impact of supplementing dairy cows with mixtures of polyherbal products supplying conjugates of choline (BioCholine, BC), lysine (OptiLysine, L) and methionine (OptiMethionine, M), considering the costs of veterinary treatments, the nutraceutical effects of the mixtures, the partial cost and returns of milk production. Eighty postpartum Holstein cows were randomly assigned to individually receive. The pellets no containing (Control, 20 cows) and containing polyherbal products (g/d) (BC20, 19 cows; BC40, 17 cows; BC20+L40+M20, 12 cows, and BC40+L80+M40, 12 cows) were offered to cows during the milking through automatic feeders in the course of 90 days in a commercial farm. Treatment costs were grouped in terms of antibiotics, healing, anti-inflammatories, glucogenics, hormonal, intra-mammary treatments, restorative and vitamins. Milk production was not affected (P>0.05) by polyherbal additives but there were numerical differences in the number of treatments and costs; animal health cost per cow showed a high variation coefficient (average 347%). Cows receiving BC40 and BC20+L40+M20 had reduced animal health cost per cow but only the treatment BC40 showed residual effects post experiment with an economic improvement of 2.1% over the control group, showing benefits associated to a reduction in the number of doses with antibiotics and doses of immune-stimulants. Cows receiving BC40 had the best milk yield numerically in combination with the lower number of animal health costs which resulted in the highest income.

Snacks are commonly eaten in western societies and, because of that, have a non-negligible effect on consumers’ health. The main objective of this work was to develop and optimize a snack formulation with sweet cherry, an important crop from the Portuguese region of Beira Interior and which has a Protected Geographical Indication (PGI). The experimental design and the optimization process were based on the Response Surface Methodology. In order to achieve that, a factorial design was implemented with three factors (almond and honey content, and baking time) and five response variables (water activity, antioxidant activity, mesophilic count, flavour and texture), and three repetitions of the central point. The optimization resulted in a formulation with 50 g 100 g-1 of sweet cherry, 35 g 100 g-1 of almond, 15 g 100 g-1 of honey, baked in the oven at 120 ºC for 13 min. The nutritional analysis showed that this product could be labelled with some nutritional claims, such as “low saturated fat”, “with no added sugar”, “salt free” and “source of fibre”.
