    Social media platforms are places where people post their feelings and thoughts about a topic. The institutions, organizations, individuals, or companies that are the subject of these ideas are affected by these posts. As discussed in different studies, companies in stock exchange markets are affected by the posts made on these social media platforms. At the same time, individuals who are aware of this fact, namely speculators and influencers, may make profit by manipulating the truth. In this study, possible speculators or influencers using the Twitter social media platform are investigated. As the target companies, Google, Amazon, Apple, Tesla, and Microsoft were chosen, which are among the largest companies on the NASDAQ stock exchange market. In the study, asentiment analysis using the Loughran and McDonald sentiment analysis dictionary was utilized. The sentiment analysis results were used to model different machine learning algorithms. With the models, individuals who had too many positive or negative effects as possible speculators or influencers were identified. The study was performed for 5 years of data. The results indicates that (1) without noise reduction, it is not possible to establish a correlation on individual tweets and their effects on the stock market; (2) it is not possible to establish a correlation between the number of tweets and the volume of companies; (3) the effect of threshold on the accuracy, which has been done and proven in different studies, has also been proven in this study; (4) RBF Kernel SVM method gives better result than other machine learning methods

    Skripsi yang berjudul“Menapak Zaman: Kisah Hidup Kasim Munafy, Tokoh Lokal Muhammadiyah Pariaman (1917-1996)” adalah sebuah penulisan biografi yang bertujuan untuk menelusuri berdirinya organisasi Muhammadiyah daerah Pariaman dan jiwa zaman yang turut mempengaruhinya. Peristiwa itu tergambar dengan melihat ketokohan Kasim Munafy secara deskriptif naratif dan mencoba mengungkap latar belakang kehidupan yang melahirkannya sebagai pimpinan Muhammadiyah. Tulisan ini menggunakan metode penelitian sejarah yang terdiri dari empat tahap, yaitu heuristik (mencari dan mengumpulkan dokumen sejarah), kritik sumber (yang terdiri dari kritik ekstern dan intern), interpretasi (penafsiran sumber), dan historiografi (penulisan sejarah). Metode pengumpulan data dilakukan dengan studi kearsipan, studi kepustakaan, dan melakukan studi sejarah lisan (melalui metoda wawancara). Hasil wawancara dilakukan dengan sepupu Kasim Syarif; tiga orang anaknya Fuad, Fakhriyati, dan Fakhrurrozi Kasmy; rekan Kasim Munafy yang aktif di Muhammadiyah dan Aisyiyah, yakni: Mansur Hasan, Asmak Bakry, Mustafa, Mariana, Chuzaimah, Aziz Chan; dan anak Sulaiman Munafy Jauhar Muiz Sulaiman. Penulisan biografi Kasim Munafy merupakan biografi tematis, yaitu penulisan biografi yang ditekankan pada tema-tema tertentu, yaitu dengan memfokuskan pada sebagian dari hal-hal penting dari kehidupan si tokoh, dengan penekanan pada latar belakang kehidupan yang mendorong Kasim Munafy sebagai aktivis Muhammadiyah dan bagaimana ia harus mendekam dalam penjara ketika dituduh terlibat PRRI hingga menghidupi keluarga dan persyarikatannya. Nagari Kurai Taji merupakan basis awal gerakan pembaruan yang dibangun oleh kaum muda Adnan gelar Tuanku Itam Ketek. Gerakan pembaruan yang berawal dari Kurai Taji itu kemudian cepat tersebar ke seluruh Padang dan Pariaman. Salah satu tokoh yang ikut mendorong perkembangan Muhammadiyah di kedua daerah tadi adalah Kasim Munafy. Tidak hanya terlibat dalam organisasi modernis Islam tersebut, Kasim juga menjabat Sekretaris II Masyumi Sumatera Tengah, Sekretaris Pertahanan Hizbullah. Bermula dari aktivitasnya di Hizbul Wathan (1929), karir organisasi dan politik Kasim pun melesat sebagai Ketua Muhammadiyah Daerah Padang Pariaman (1952-1995) dan anggota DPRDS Padang Pariaman (1956-1958). Meskipun tidak turut berjuang dengan PRRI, ketika ibu kandungnya terserang sakit, Kasim Munafy harus berjuang untuk menembus wilayah Sumatera Barat dan mendekam dibalik jeruji besi ketika dituduh ikut memberontak. Ketika masa Gestapu berakhir, Kasim kembali larut dalam aktivitasnya mengelola dan mengembangkan amal usaha Muhammadiyah daerah Padang Pariaman

    Temel İslam Bilimleri birbirleriyle ilgili olsa da hâkim olarak yetişen Ali Himmet Berki’nin branşı İslam Hukuku’dur. Ancak Temel İslam Bilimlerinde çok yönlü biri olması nedeniyle, hadis alanında da eser vermiştir. Eserlerini yoğun olarak emeklilik döneminde yazmıştır. “Cumhuriyet Dönemi Hadis ve Şerhi” kapsamında olan bu eseri ve müellifini “hadis ilimleri açısından tanımak ve tanıtmak” faydalı olacaktır diye düşünüyoruz. Güncel olan bazı sosyal, ekonomik ve hukukî meselelerdeki görüşlerini hadislerden yola çıkarak açıklamıştır. Böylece yaşadığı dönemin dinî ve geleneksel hayat tarzına ayna tutmuştur. Bu bakımdan eserin ahlakî, fıkhî boyutu yanında sosyolojik boyutu da bulunmaktadır. Döneminde, her esere nasip olmayacak bir ilgiye mazhar olmuştur.yo

    Atatürk\u27ün maddi varlığının aramızdan ayrılışından 47 yıl sonra, bir 10 KASIM’ı daha yaşıyoruz. O, «İki Mustafa Kemal vardır: Biri ben, ölümlü Mustafa Kemal, öteki ulusun içinde yaşattığı Mustafa Kemaller ülküsü.» Yine O, «Beni görmek demek, behemahal yüzümü görmek demek değildir. Benim düşüncelerimi ve duygularımı anlıyorsanız ve duyuyorsanız bu yeterlidir» diyordu. Ulu Önder Atatürk, bu iki sözüyle, 10 KASIM’lara nasıl bakmamız gerektiğini vurgulamaktadır. Ben bu yazımda kısaca, Ata’mızın bu sözlerinden yola çıkarak, 10 KASIM\u27lara bakış açımızın ne olması gerektiğini belirtmeye çalışacağım. Ayrıca, Atatürk\u27ün Türk gençliğine verdiği bazı buyrukları anımsatarak, gençlerimizin, Ata’mıza karşı olan görev ve sorumluluklarını dile getirmeye çalışacağım.Atatürk\u27ün maddi varlığının aramızdan ayrılışından 47 yıl sonra, bir 10 KASIM’ı daha yaşıyoruz.

    Portals of Nuruosmaniye Mosque

    No full text
    Nuruosmaniye Mosque, which was beginning to be built by the order of Sultan Mahmud I's order and completed after his death by his brother Sultan Osman III, is the most important building of Ottoman Westernization Period architecture. Architects of the complex, which includes a mosque, a sultan's pavilion, a madrasa, a library, a tomb, a sebil, a fountain, an imaret, and shops, are Mustafa Agha and his aide Simeon Kalfa. The mosque has a planning scheme formed by the square-planned prayer area covered with a single dome, the polygonal mihrab projection on the south wall, and the semi-oval courtyard to the north. The traditional scheme imposed on the main body of the mosque and the Baroque effect on the mihrab and courtyard wall; make the mosque an example that shows traditional and westerner applications together. Nuruosmaniye Mosque is a transition era example that started moving away from classical lines of Ottoman architectural tradition yet abide by classical norms. The architectural design of the praying area consists of a square planned section covered by a single dome carried by four great arches that had been seen in Ottoman architecture before. Moreover, the implementation of merging the praying zone with the courtyard since the 15th century shows that settlement principles were maintained. From this aspect, while the mosque continues to reflect the traditional architecture, the semi-elliptical planned courtyard of the mosque is the first concrete example of how art movements originated in the West from the first quarter of the 18th century onwards affected mosque plans. The semi-elliptical form of the courtyard that reminds the elliptical implementations of the Baroque era has been related to the Baroque style in Europe. A similar situation was observed on the portals of the mosque in which traditional and western practices are used together. While portals reflect the traditional scheme in planning, baroque characters are exclusively preferred in ornaments. The traditional scheme which was constituted with side niches located on both sides of the side wings and the intrados of the main niche is continued to be used. Although the plan is traditional, usage of baroque style ornaments solely shows that classical and western implementations were evaluated together. Horizontal moldings filled with baroque style ornamentations replaced intrados filled with muqarnas. This innovation seen in decoration shows itself in the context of architectural elements in the replacement of small columns by plasters corners on side niches of the main niche. Especially preferring not to place the main niche on the design of the inner court northern-side portal is a clear sign of change in the portal plans. In addition, placing independent decorative columns on the front side of the same portal shows that it had been influential on the other selatin mosques built after Nuruosmaniye Mosque. This change and transformation regarding portal designs and plans tell us that portals in Ottoman architecture were continued to be designed and implemented as they were treated in traditional styles until Ottomans meet western affected art movements. The aforementioned alterations started with Nuruosmaniye Mosque would affect other examples in the second half of the century and give a place to designs with more ornamental styles.Scientific Research Projects Coordination of Pamukkale UnivThis study derived from the PhD thesis titled The portals in the eighteenth century Istanbul structures which was completed in 2020 under the supervision of Prof. Dr. Kasim Ince, in the Pamukkale University - Institute of Social Sciences - Department of Art History.
