  Natural Poetry: Conceptualizing A Poetic Quest in the Late Ottoman Period

  Çetin, Mehmet Akif

  The aim of this study is to reveal the scope of the term natural poetry as a concept, which is frequently encountered in poetic texts published in the nineteenth century and the first quarter of the twentieth century. Naturalness has been transformed into a useful tool for the poetics of new poetry due to its positive connotations such as natural, non-artificial, spontaneous, normal. After Tanzimat, when a new poetic tradition was intended to replace classical poetry, naturalness was conceptualized to emphasize that the new poetry was the normal and natural style of poetry. According to the innovators, the poetic devices of classical poetry distort the naturalness of text and discourse. The desired new poetry is to be purified from the artificialities and excesses of the old poetry. For this purpose, it is necessary to return to the syllabic meter, which is an indigenous verse, to get rid of the artificial discourse of classical poetry and to revive our own poetic tradition. At this point, the concept of natural poetry was started to be used by the innovators to express the new poetry that had attained natural expression, got rid of the aruz meter, and was produced easily and without artifice. However, each poet seems to point to a different dimension of the new poetics to be constructed with the concept of natural poetry. In this article, what the poets wanted to express with the concept of natural poetry will be explained and the differences in the use of the concept will be emphasized. Thus, the poetic renewal after Tanzimat will be evaluated in the light of the concept of natural poetry in terms of poetic goals.

  Α Καισαρ without a Βασιλενς: TIBERIUS II CONSTANTINE'S EASTERN POLICY BETWEEN 574-578 CE

  Konuk, Suha

  The peace treaty concluded in 562 between Emperor Justinian I and the Sasanian ruler Khosrow I was broken in 572 by Justin II(565-578). The war, launched with considerable expectations, turned into a grave disaster for Byzantium with the loss of the strategic frontier city of Dara in 573. Following these developments, Justin II's mental health deteriorated completely, rendering him entirely incapable of governing. The Caesar Tiberius effectively assumed power in the shadow of Empress Sophia and ruled the empire with the title of Caesar until Justin's death in 578. The failure of Byzantium's siege of Nisibis in spring 573, and moreover the loss of Dara, compelled Byzantium to seek an urgent truce with the Sasanians. During this period, Tiberius aimed to maintain peace at any cost until a new army could be established. However, the appointment of Maurice as magister militum per Orientem in 578 marked a decisive turning point in this defensive doctrine, enabling Byzantium to regain the initiative on the eastern front. This article focuses on how Tiberius II managed the Sasanian war during the four years he governed the empire with the title of Caesar.

  A new cave-dwelling Laemostenus (Pristonychus) species from central Anatolia (Coleoptera: Carabidae: Sphodrini)

  Fidan, Ebru ceren; Elverici, Mert

  Laemostenus (Pristonychus) violeta Fidan & Elverici, sp. nov., from T & uuml;rkiye is described and illustrated. The new species belongs to the terricola species group of the subgenus Pristonychus. It is readily distinguished from congeners by the unique structure of the aedeagus (slender median lobe and distinct apical shape) and the vivid violaceous sheen of the elytra. The species was found in extremely high abundance in the guano-rich dark zone of Singildakli in (Hamambogazi) Cave, Central Anatolia, and was absent from a nearby guano-free cave. Its ecology indicates a guanophilic and troglophilic lifestyle, and it is currently known only from the type locality, suggesting a localized cave endemicity within the group.

  Exploring novel Fermat polynomials and their transformative properties

  Kuloglu, Bahar; Eser, Engin; Özkan, Engin

  In this research, we present a novel family of polynomials that are derived from Fermat numbers. Alongside these newly introduced polynomials, we provide a series of important identities and properties, including the Binet formula and generating functions, which are fundamental to understanding their structure. We also show that Fermat polynomials can be efficiently expressed using matrix representations, enabling an exploration of fundamental properties derived from the invariance of the determinants of these matrices. This approach provides new perspectives on the internal connections within these polynomials. In addition, many different transforms have been considered with the help of polynomials of these new number sequences, and these transforms can play a role in many areas from secure key generation to differential equation solutions. These transformations shed light on the deeper structural properties of the Fermat polynomials and reveal intricate connections between these polynomials and other well-established mathematical constructs, enhancing our understanding of their broader implications in the field of number theory and beyond.

  Mesostigmatid mites (Acari: Parasitiformes) from the aphotic zone of Hacı Akif Cave (Türkiye), with the description of a new species of Macrocheles

  Özbek, Hasan Huseyin; Elverici, Mert

  This study reports mesostigmatid mites (Acari: Mesostigmata) collected from fresh bat guano in the aphotic zone of a natural cave in T & uuml;rkiye. Three species were identified, each belonging to a different family: Eulaelaps stabularis (Haemogamasidae), Macrocheles foliatus & Ouml;zbek sp. nov. (Macrochelidae) and Vulgarogamasus oudemansi (Parasitidae). Macrocheles foliatus & Ouml;zbek sp. nov. is described here as a new species based on morphological features observed in adult females. Vulgarogamasus oudemansi is recorded from T & uuml;rkiye for the first time. Two females of Eulaelaps stabularis were found directly in bat guano, and the presence of developing larvae suggests larviparity or ovolarviparity in this species. These findings expand current knowledge of cave-associated mesostigmatid diversity and provide additional information on the ecological role of bat guano habitats in supporting diverse mite assemblages in cave ecosystem.https://zoobank.org/urn:lsid:zoobank.org:pub:745CF591-023A-48F3-A4E9-824BB6923106

  The Mediating Role of Emotion Regulation Difficulty and Career Decision Self-Efficacy in the Relationship Between Separation Anxiety and Career Adjustment

  Çelik, Oğuzhan

  The aim of this study was to examine the structural relationships between separation anxiety and career adaptability, career decision-making self-efficacy, and emotion regulation difficulties. The sample of the study consisted of 976 university students, 687 female (70.5%) and 287 male (29.5%), aged between 17 and 29 years. Participants completed self-report measures of the variables studied. Structural equation modelling was used to explore the complex relationships between these variables. According to the results of the study, there is no significant relationship between separation anxiety and career adaptability and career decision-making self-efficacy. In addition, there is a significant positive relationship between separation anxiety and emotion dysregulation and between career adaptability and career decision-making self-efficacy. There is also a significant negative relationship between emotion dysregulation and both career adaptability and career decision-making self-efficacy. In addition, the relationship between separation anxiety and career adjustment is mediated by emotion dysregulation alone and by emotion dysregulation and career decision-making self-efficacy together.

  Species of the genus Stigmaeus (Acariformes: Stigmaeidae) from the Karasu Valley (Türkiye): morphological examination and a taxonomic argument

  Doğan, Salih

  In the present work, morphological characteristics of species of the genus Stigmaeus Koch collected from the Karasu Valley in the Munzur Mountains (Türkiye) were examined. A total of 11 species of the Stigmaeus were identified in this study. Among them, S. dokeri, S. maraghehiensis and S. purpurascens are recorded for the first time from Türkiye. The protonymph and deutonymph stages of S. bifurcus, as well as the larva, protonymph and deutonymph stages of S. dokeri, are described for the first time. Furthermore, morphological variations were observed for the first time in S. dokeri and S. pulumurensis. The names Stigmaeus africanus Soliman & Gomaa, 1986, S. banksi Gomaa & Hassan, 1986, S. triramus Soliman & Gomaa, 1986 and S. zaheri Gomaa & Hassan, 1986 are considered nomina nuda. This study also highlights the importance of maintaining the current concept of the genus Stigmaeus for taxonomic stability. While the available molecular data suggest that some species may form distinct clades, single-locus analyses based on limited data sets are not yet considered sufficient to justify clear divisions at the genus level. Therefore, it has been suggested that a more balanced approach would be to cautiously consider the idea of dividing Stigmaeus into separate genera and to restructure it based on subgenera or natural species groups, in accordance with the concept of Berlese (1910), and the aim is to open this systematic framework for discussion. In this context, the proposal to reinterpret certain taxa such as Ledermuelleriopsis Willmann and Villersia Kuznetsov not as independent genera but as subgenera within Eustigmaeus Berlese has also been opened for discussion within the scope of this unifying approach. In conclusion, this study contributes to the diversity of Stigmaeus in Türkiye with new records, documents different developmental stages and morphological variation, clarifies the nomenclatural status of some species-names, and advocates a taxonomic framework that prioritises subgeneric re-structuring over generic-level splitting within Stigmaeidae systematics.

  Şair Kimliğinin Alımlanışında Diyalektik, Süreklilik ve Kopuş

  Çetin, Mehmet Akif

  Bu çalışmanın amacı, şair kimliğinin 19. yy. ve sonrasında uğradığı dönüşümü ve tarihsel süreçte kavramın alımlanışındaki süreklilikleri ortaya koymaktır. Makalede şair kavramının kökenleri ile 19. yy. ve sonrasında şair tanımları arasındaki ortaklıklar ve farklar tespit edilmiştir. Bazı kaynaklar, şairi şiirin teknik gerekliliklerine atıfta bulunarak açıklamaktadır. Ancak şiirin değişen tekniği, sözü edilen tanımları bir süre sonra geçersiz kılmaktadır. Bazı kaynaklar ise şairi sahip olduğu doğal ve sıra dışı yetenek aracılığıyla tanımlama yoluna gitmiştir. Tanımlamalara bakıldığında şair kavramının tüm şiir üreticilerini kapsayan tutarlı ve kapsamlı bir tarifinin yapılamadığı görülmektedir. Ayrıca şairlik bir vasıf olarak edebî lisans ve ehliyet olarak değerlendirilmektedir. Eski Türk toplumlarında şairler; hekimlik, sihirbazlık ve bilgelik gibi çoklu kimliklere sahiptir. Bu kimliklerin zaman içinde ortadan kaybolmasına karşın şairler geçmişte sahip oldukları ayrıcalıklı konumlarını korumaya devam etmişlerdir. Modern şair kimliği, geçmişten farklı olarak kutsal ve metafizik ile olan bağlarından arındırılmıştır. Ancak edebî üretimin kendisi, kaybedilen kutsallığa geri dönüş arzusu olarak değerlendirilmiştir. Dolayısıyla seküler şair kimliği geçmişte kutsal olandan kaynaklanan imtiyazlı pozisyonunu edebî marifet ve sahip olduğu düşünülen doğal yetenek aracılığıyla korumaya devam etmiştir. Öte yandan şairlere daima şüphe ile yaklaşılmıştır. Onlar ideal bir düzenin düşmanları olarak görülmüş ve iktidarlar tarafından tehdit olarak algılanmışlardır. Şairlere karşı duyulan şüphe, tarihsel olarak süreklilik göstermektedir.

  The potential of Barbarea species in the management of obesity, hyperlipidemia, and diabetes

  Badem, Merve; Kanbolat, Şeyda; Kandemir, Ali; Öztürk, Ayşe Aleyna; Topcu, Hayrünnisa

  Barbarea species belonging to the Brassicaceae family contain glucosinolates, flavonoids, phenolic acids, saponosides, fatty acids, and other bioactive compounds. These compounds are reported to exhibit antioxidant, antimicrobial, antimutagenic, antiproliferative, and herbicidal effects, as well as beneficial effects on metabolic diseases. In particular, organosulfur and polyphenolic compounds have been reported to exhibit inhibitory effects on enzymes such as cyclooxygenase, lipoxygenase, nitric oxide synthase, pancreatic lipase, lipoprotein lipase, and glucosidase. In this study, the inhibitory activities of methanol extracts, chloroform, ethyl acetate, and remaining aqueous subfractions obtained from the aerial parts of B. auriculata var. paludosa Coode& Cullen and B. plantaginea DC on pancreatic lipase, cholesterol esterase, and α-glucosidase enzymes were investigated for the first time. When the results obtained in the study are evaluated, the ethyl acetate subfraction of B. plantaginea exhibited the strongest pancreatic lipase and cholesterol esterase inhibitory activities, with IC₅₀ values of 111.687 ± 1.291 µg/mL and 10.718 ± 0.308 µg/mL, respectively. For α-glucosidase inhibition, the methanol extract of B. auriculata subsp. paludosa demonstrated the highest activity with an IC₅₀ value of 135.207 ± 0.136 µg/mL. it is seen that the ethyl acetate subfraction of both species has stronger cholesterol esterase inhibitory effects, moderate lipase and glucosidase inhibitory effects.

  COVID-19 Pandemi Döneminde Erzincan Kent Merkezinde Trafik Kazalarının Zaman-Mekân Küpü Yöntemiyle Zamansal – Mekânsal Analizi (2020-2023)

  Kesik, Ozan Arif; Güney, Ertuğrul

  Bu çalışma, 2020-2023 döneminde Erzincan kent merkezinde meydana gelen ölümlü ve yaralanmalı trafik kazalarının zamansal ve mekânsal dinamiklerini, COVID-19 pandemisinin etkileri bağlamında incelemektedir. Erzincan, Doğu Anadolu Bölgesi’nde bin kişi başına düşen araç sayısında birinci sırada yer alması ve düşük nüfusuna rağmen yüksek kaza istatistikleri göstermesi nedeniyle çalışma alanı olarak seçilmiştir. Araştırmada; Sıcak Nokta Analizi (Getis-Ord Gi*), Kernel Yoğunluk Analizi ve Zaman-Mekân Küpü Analizi yöntemleri kullanılarak kazaların dağılımı haritalanmıştır. Ayrıca, Analitik Hiyerarşi Süreci (AHP) ile kaza risk faktörleri ağırlıklandırılmıştır. Bulgular, COVID-19 kısıtlamalarının yaşandığı 2020 yılında kaza sayılarında belirgin bir düşüş yaşandığını, ancak normalleşme süreciyle birlikte 2023 yılında kaza ve yaralı sayılarının pandemi öncesi seviyeleri aşarak zirve yaptığını ortaya koymuştur. Mekânsal analizler, kaza riskinin Dörtyol kavşağı ve ana arterler üzerinde "yoğunlaşan sıcak nokta" karakteri sergilediğini; AHP sonuçları ise trafik yoğunluğu (%46) ve hızın (%33) temel risk faktörleri olduğunu kanıtlamıştır. Çalışma, elde edilen bulgular ışığında, riskli kavşaklar ve trafiğin zirve yaptığı saatler için yerel ölçekte uygulanabilir trafik güvenliği stratejileri sunmaktadır.
