Teknoloji Çağında İnternet ve Sosyal Medya Kaynaklı Yeni Nesil Korkulara İlişkin Bir İnceleme
Teknoloji çağında, internet ve sosyal medya platformları, kişilerarası iletişimden bireylerin gündelik hayatına, benliklerine ve rutinlerine kadar pek çok alanda köklü değişiklikler yaratmıştır. Bu çalışma, teknoloji çağında bireylerin internet ve sosyal medyayla olan ilişkilerini ve bu platformların bireylerde yarattığı yeni nesil korkular ile olumsuz etkileri incelemektedir. Sosyal medya kullanımının bireylerde “FoMO” (Gelişmeleri Kaçırma Korkusu), sosyal medya bağımlılığı, kıskançlık, yetersizlik ve dışlanmışlık hissi gibi psikososyal etkiler yarattığı tespit edilmiştir. Ayrıca, sosyal medyanın karanlık yüzü (DoSM) olarak adlandırılan siber zorbalık, mahremiyet ihlalleri, Stres-Gerginlik-Sonuç (Stressor-Strain-Outcomes) ilişkisiyle dezenformasyon ve bir stres tetikleyici olarak işlev görmesi bireylerde yeni nesil korkular ve kaygıların artmasına neden olmaktadır. Türkiye açısından da önemli bir konu olan sorunlu internet kullanımını analiz eden çalışma, sosyal medya ile kurulan ilişkinin hem psikolojik hem de fiziksel sonuçlarına değinmektedir. Sonuç olarak, sosyal medya bireyler için iletişim ve bilgiye erişim kolaylığı sağlasa da, aşırı kullanımı psikososyal ve fiziksel sorunlara yol açabilmektedir. Çalışma, sosyal medya bağımlılığı ve yeni nesil korkuların bireylerin yaşam kalitesine etkisini ele almakta ve dijital dünyada bilinçli kullanım stratejilerinin önemini vurgulamaktadır.

İTÜ-TV’den TRT’ye Türkiye’de Televizyon Tarihi ve Dijitalleşme
1925 yılında mühendis John Logie Baird tarafından İngiltere’de icat edilen ve ilk yayını 1936’da yapılan televizyonun Türkiye’ye gelişi uzun bir zaman diliminin ardından gerçekleşmiştir. Ülkemizde televizyon denilince akla ilk gelen kurum Türkiye Radyo Televizyon Kurumu (TRT) olsa da aslında bu yolculuğun pek fazla bilinmeyen bir öncesi bulunmaktadır. Türkiye'de televizyon yayıncılığı, ilk kez 1952 yılında İstanbul Teknik Üniversitesi’nde başlatılmış olup, o günden bu yana hızla gelişerek büyük bir dönüşüm geçirmiştir. İlerleyen günlerde İstanbul Teknik Üniversitesi Televizyonu (İTÜ-TV) yayın akışı haftanın bir günü ve birkaç saat şeklinde düzenlenmiştir. 1960’larda televizyon alıcılarının sayısı artmış ve gündelik hayatta insanların birbirlerine televizyon izlemeye gittiği bir misafirlik dönemi başlamıştır. Bu kapsamda çalışmamızda Türkiye’de İTÜ-TV’den TRT’ye uzanan başlıklarıyla televizyonun tarihçesi, toplumsal hayata kattığı yenilik ve değişimler ve bu hikâyenin günümüz dijital çağındaki yeri TRT özelinde irdelenecektir. Bu amaçla, TRT’nin yayın hayatına başlangıcı ve gazetelerdeki yansıması arşiv taraması üzerinden incelenecek ve elde edilen haberler üzerinden içerik analizi yapılacaktır. TRT’nin günümüze dek geçirdiği değişim ve yenilikler üzerine yapılacak literatür taraması ile de dün ve bugün arasındaki bağın genel bir resmi çizilecektir. Türkiye’nin 100 yıllık birikimi içerisinde televizyon yayıncılığı alanında yerelden küresele damgasını vuran TRT’nin attığı adımların izini sürmek ve toplumsal yaşamdan başlayarak ülke tarihine etkilerini incelemenin iletişim literatürüne önemli bir katkı sunacağı öngörülmektedir.

Exploring the concept of financial domination on social media: sentiment and text analysis on Twitter
In today’s digital culture, we face a new behavior that started on Twitter, a social media platform with a large user base. This study explores how users participate in the financial slave-themed Twitter discussions and the master-slave relationship network. Accordingly, the sample consisting of the Twitter account messages which seek to meet financial slaves and mistresses is examined using text and sentiment analysis. Within the scope of the study, 277,293 tweets related to financial slavery were collected between May 2020 and November 2021, and text/sentiment analysis were performed on findom (financial domination) tweets. The keywords used in the analysis were selected from the most tweeted concepts related to financial domination and slavery (“financial slave,” #financialslave, #findom, #humanatm, #paypig, “financial domination”). The analysis of the discursive structures in the text/sentiment analysis results revealed that certain sentiments and emotions such as trust and joy were pre-requisite to establish online findom relationship. Female domination (femdom) related tweets were more prevalent in tweets while the edges between findom fetish and other kinks (foot fetish, bdsm, porn etc.) were somewhat blurred on Twitter. These show that there are vibrant user base and community on Twitter and the studies like ours are important to understand communicative dimension of financial domination.

World Health Organization’s Twitter Use Before and During Covid-19 Pandemic: Sentiment and Textual Analysis of Tweets
Social media as a form of mass self-communication offers a great deal of potential and opportunities for users and organizations to get, diffuse, redistribute, and monitor information and messages due to its features of accessibility, digitality, and time-space independence. Especially during a crisis, being able to harness the power of social media is an im- perative management practice not only to provide the public with accurate information but also to deter misleading claims and rumors regarding the subject. Based on this assumption, this study aims to measure and compare the overall sentiment of the World Health Organization’s (WHO) tweets before and during the coronavirus pandemic. Along with the overall senti- ment of tweets, the contents of tweets, and the WHO’s Twitter use practices before and during the pandemic were assessed in the framework of crisis management and health communication. Within the scope of our study, the WHO’s 34.673 tweets between 2018 and 2021 were examined with sentiment and textual analysis. The study also indicates the health policies be- fore and during the covid19 pandemic and crisis management tactics by analyzing and close reading the WHO’s tweets. The findings reveal that the WHO posted more tweets to inform the public and minimize infodemic while it deliberately preferred positive messages (words and sentiments) in its tweets during the pandemic.

A text mining analysis of the change in status of the Hagia Sophia on Twitter: the political discourse and its reflections on the public opinion
The Hagia Sophia served as a museum from November 24th, 1934 until it was reopened for worship on July 24th, 2020 with a Presidential Decree of the Republic of Turkey. As a result of the change in status of the Hagia Sophia, there have been discussions on Twitter. Hence, aiming to present text and sentiment analysis of those Tweets, text mining as a sub-branch of data mining is used as a methodology, which is for achieving meaningful information and outputs from raw data by configuring systematic ordering of unstructured data by using natural language processing methods and tools. In this research, 102,430 tweets that include Hagia Sophia as a word and a hashtag from July 10th, 2020 -that the status change of the Hagia Sophia was declared- to June 12th, 2021 are resolved and analyzed using the frequency, sentiment and network analysis. In conclusion, although there are more positive sentiments than the negative ones, the negative sentiment is clearly a discontent and backlash especially against Turkey and Islam. Furthermore, it becomes clear that Islam is associated with terrorism and radicalism.

A Sentiment Analysis and Role of Twitter for Health Communications
Social media has been in our lives so much lately that it is an undeniable fact that global pandemics, which constitute an important part of our lives, are also affected by these networks and that they exist in these networks and share the users. The purpose of making this hashtag analysis is to reveal the difference in discourse and language while analyzing Twitter data and to evaluate the effects of a global pandemic crisis on language, message, and crisis management with social media data. This form of analysis is typically completed through amassing textual content data then investigating the “sentiment” conveyed. Within the scope of the study, 11,300 Twitter messages posted with the #stayhome hashtag between 30 May 2020 and 6 June 2020 were examined. The impact and reliability of social media in disaster management could be questioned by carrying out a content analysis based totally on the semantic analysis of the messages given on the Twitter posts with the phrases and frequencies used.
