CUMHURİYET DÖNEMİNDE (1923-1950) TARİH EĞİTİMİ VE JOHN DEWEY’İN EĞİTİM KONUSUNDAKİ GÖRÜŞLERİNE GENEL BİR BAKIŞ
Authors: DUMAN Süleyman
Published: December 2023

Osmanlı Devleti’nin kuruluşundan itibaren 1908’de ilan edilen II. Meşrutiyet’e kadar hâkim olan dini ve hanedan merkezli tarih anlayışı, 19. Yüzyılda tarih anlayışlarında meydana gelen değişiklikler ve Osmanlı Devleti’nin geçirmiş olduğu süreç, devlet yönetiminde etkin olan zümrenin Türkçü ve milliyetçi bir tarih anlayışına yönelmesine sebep oldu. Osmanlı Devleti’nin kuruluşundan itibaren süregelen gelenekçi tarih anlayışı devletin fiilen ortadan kalktığı dönemlere kadar sürdü.

Mustafa Kemal Atatürk öncülüğünde kurulan Türkiye Cumhuriyeti’nde ise dini ve hanedan merkezli tarih anlayışı yerine milli ve Türkçü bir politika izlenmeye başladı. Siyasi ve askerî alanda varlığını kanıtlayan Türkiye Cumhuriyeti, tarih ve kültürel alandaki çalışmalar ile bu başarılarını pekiştirme amacındaydı. Bu amaç doğrultusunda çeşitli araştırmalar yapılmaya başlandı ve Türk Tarih Tezi araştırmaya ve eleştiriye açık tezler ortaya atıldı.

Cumhuriyetin ilanından sonra Batılı anlamda bir eğitim modeli benimsendi ve söz konusu eğitim sistemi hakkında görüşlerine başvurulmak üzere bir takım yabancı araştırmacılar Türkiye’ye davet edildi. Bunlardan ilki Kolombiya Üniversitesi Öğretim Üyesi Prof. John Dewey idi. 1923 yılında davet edilen Dewey, 1924 yılında Türkiye’ye gelerek; İstanbul, Ankara ve Bursa’da çeşitli temaslarda bulundu ve Türk eğitim sistemi hakkında raporlar sundu. Batılı eğitimcilerin sunmuş olduğu bu raporlar Türkiye’deki eğitim sistemine katkı sunmuş ve gelişmesi için yol gösterici olmuştur.
Stacking Ensemble and Federated Learning for IoT Intrusion Detection
Authors:   , Lazzarini Riccardo
Published: December 2023

The number of Internet of Things (IoT) devices has increased considerably in the past few years, which resulted in an exponential growth of cyber attacks on IoT infrastructure. As part of a defense in depth approach to network security, intrusion detection systems (IDS) have acquired a key role as they attempt to detect malicious activities promptly and efficiently. In this thesis, an investigation on the use of ensemble learning and federated learning as methods to develop IDS in IoT environment is proposed. Three main contributions are offered, which were evaluated on two open-source datasets, namely ToN IoT and CICIDS2017. The first contribution is a novel method based on a combination of ensemble models. The method uses ensemble stacking and boosting to detect anomalies in IoT traffic. Three machine learning models, namely kNN, Decision Tree and Logistic Regression, are used as the base learners for the stacking model. The XGBoost model is used as the meta learner. Results show that the proposed model is capable of high accuracy, precision, recall and F1-Score in both datasets in binary and multi-class classification. Secondly, this thesis proposes another novel IDS approach based on a stacking ensemble of deep learning (DL) models. This approach is named Deep Integrated Stacking for the IoT (DIS-IoT), as it combines four different DL models into a fully connected DL layer, creating a standalone ensemble stacking model. Results demonstrate that DIS-IoT is capable of a high level of accuracy with a very low False Positive rate (FPR) in both datasets improving on other standard, standalone, DL methods. Results from this set of experiments were also compared against results available in the literature, which were obtained from similar approaches on the ToN IoT dataset. DIS-IoT achieves comparable performance with others in binary classification, but outperforms them in multi-class classification. The third contribution uses Federated Learning (FL) as an alternative, distributed, method to a centralized intrusion detection model. The FL model is composed of four clients and one server. Data analysis was performed at the client side, each using their own portion of the dataset. No data sharing between participants occurred, hence maintaining data privacy. The results from the experiments demonstrated that a collaborative federated system using horizontal data partitioning and the FedAvg aggregation algorithm, can have a comparable performance with a centralized model, making it a viable option for an IoT IDS. Moreover, several other federated averaging algorithms were evaluated in order to verify their efficacy in this setting. These were FedAvgM, FedAdam and FedAdagrad. The experiments demonstrated that FedAvg and FedAvgM were the most efficient options in the given scenario. However, further research in alternative, larger, settings are required to evaluate FedAdam and FedAdagrad more accurately.
Testamentul doamnei Agnes, văduva lui Petrus Moldner din Bistrița (1531)
Authors:   Institutul de Istorie „George Bariţiu” din Cluj-Napoca al Academiei Române, Lidia Gross
Published: December 2023

The last will and testament, situated on the border between oficial and private, becomes a privileged source for the reconstruction of what is generically called „microhistory”. Less studied Transylvanian urban testaments from the medieval and pre-modern periods provide ample support for the identification of the testator's family cosmos, his community of residence, the ties he formed therein, etc. The testament of Mrs. Agnes (1531), the widow of Petrus Moldner, a merchant whose ascension ensured his access to the city council of Bistrița, becomes an important source for the restitution of some aspects of material civilization characteristic of the urban elite, of the interpersonal relationships that family members had established, and not ultimately for outlining the piety that was characteristic of the testator. Heiress to a sizable fortune, Mrs. Agnes donated it primarily to save her own soul at a time when the religious Reformation is also felt in Bistrița. This fact caused the „reaction” of 19th century historians, who were astounded by this woman's adherence to the values of the Catholic Church. Beyond the already existing rivalries, the magistrate's objection reflectes the lay authority's attempt to halt these donations pro salute anime, in accordance with the Saxon University's ruling in 1525 and the new reforming atmosphere.
Principesa Maria Christierna de Habsburg: femeia fatală a Transilvaniei?
Authors:   Institutul de Istorie „George Bariţiu” din Cluj-Napoca al Academiei Române, Vizauer Victor V.
Published: December 2023

In this article I have presented as synthetically as possible the „story” of Princess Maria Christierna von Habsburg (1574-1621) – the wife of Sigismund (Zsigmond) Báthory (1572-1613), Prince of Transylvania – at the same time trying to capture the most important aspects of the period she spent in the Principality (1595-1598). Some contemporary authors and later some historians saw in her the „fatal” woman for Transylvania, because Sigismund – who shortly before the wedding discovered a manly dysfunction – would have lost his peace and his ability to make the best decisions both for his country and for himself. Therefore a question arises: was Maria Christierna „fatal” for Transylvania?
Weaponizing Sexual Identities: Homosexuality as Public Scandal in interwar Romania
Authors:   Universitatea Babeș-Bolyai, Dălălău Andrei
Published: December 2023

The present paper intends to provide a preliminary analysis of the social status of the homosexual minority in interwar Romania, applying the theoretical framework of „symbolic violence” defined by sociologist Pierre Bourdieu on the case study represented by the „Credința” press scandal from 1934-1935. The scandal opposed director Sandu Tudor and the editorial staff of „Credința” newspaper on the one hand, and Petru Comarnescu, Al.Chr. Tell, Mircea Vulcănescu and Gabriel Negry (members of the Criterion Association), on the other hand. The novelty of this study consists in integrating the press scandal into the broader scheme of social and economic interactions between different agents from the social field, emphasising their competition for symbolic capital which would legitimise them in defining the nation. The study reached the preliminary conclusions that homosexuality was a cultural identity instrumentalised and then weaponised in order to gain public legitimacy and that attributing sexual meanings to a minority was produced by groups which arrogated themselves the monopoly of moral normativity.
Grupul Etnic German din România și Serviciul Special de Informaţii (1940-1944)
Authors:   Institutul de Istorie „George Bariţiu” din Cluj-Napoca al Academiei Române, Traşcă Ottmar
Published: December 2023

One can safely state that the «Andreas Schmidt era» (1940-1944) could be considered one of the most difficult periods of the history of the German minority in Romania. From the very beginning, the activity of Nazi controlled organization entitled the German Ethnic Group in Romania and its leader (Andreas Schmidt) was perceived by the Romanian authorities with suspicion and concern. This concern was legitimate since the aggressive policies of the leadership of the German Ethnic Group in Romania let to increasing tensions between the latter, on one side, and the Romanian authorities and the Romanian local population in mixed Romanian-German communities, on the other side. Consequently, the Special Intelligence Service (Serviciul Special de Informaţii, one of the Romanian secret services in the interwar period), the intelligence service of the Romanian army (entitled in Romanian: Secţia a II-a Informaţii a Marelui Stat Major), the General Inspectorate of the Gendarmerie, and the General Directorate of the Police kept under close surveillance the hostile activities of the German Ethnic Group towards the Romanian state. The reports of these aforementioned intelligence institutions emphasized the totalitarian character of the German Ethnic Group in Romania and illustrates how this Nazi controlled organization turned under the leadership of Andreas Schmidt into an effective tool of the Third Reich in South Eastern Europe.

Authors:   Universitatea „Ovidius” din Constanța, Omer Metin
Published: December 2023

"At the end of the Second World War, in search of a favorable image on international level, the Romanian Government appointed four renowned intellectuals as heads of mission in the capitals who had priority in Romania's foreign policy: Simion Stoilov in Paris, Mihai Ralea in Washington, Tudor Vianu in Belgrade, Iorgu Iordan in Moscow and Grigore C. Moisil in Ankara. In the case of all of them it was the only experience as an ambassador. In this work, Grigore C. Moisil's mandate as ambassador to the Republic of Turkey is analyzed. The analysis has three main objectives. Firstly, the goals of his mandate as ambassador are examined. Secondly, his position regarding the Romanian diplomats in Turkey that refused to accept the authority of the communist Government in Bucharest is examined. Finally, the effects of the different orientations of Romania and Turkey in the new post-war configuration and the way in which this reality influenced the position and behavior of the Romanian diplomat are explained. The article is based on unpublished archival documents, documents from Grigore C. Moisil's personal archive kept at the Romanian Academy Library and his partially published correspondence."

Published: December 2023

Introduction: Gestational diabetes mellitus (GDM) is a growing public health concern with potential long-term consequences for both mother and child. Emerging evidence suggests that GDM may impact maternal cognitive function, but the underlying mechanisms remain unclear. This prospective cohort study investigates the association between GDM and long-term cognitive function in mothers, exploring potential neuroimaging correlates.
Methods: Pregnant women were recruited from antenatal clinics in Bandung, Indonesia, between 2018 and 2020. GDM was diagnosed using the International Association of Diabetes and Pregnancy Study Groups (IADPSG) criteria. Cognitive function was assessed at 6 months, 1 year, and 3 years postpartum using a comprehensive neuropsychological battery. A subset of participants underwent structural and functional magnetic resonance imaging (MRI) at 3 years postpartum.
Results: Women with GDM exhibited lower scores on tests of executive function, processing speed, and memory compared to women without GDM at all follow-up assessments. MRI analysis revealed alterations in brain structure and function inwomen with a history of GDM, including reduced gray matter volume in the prefrontal cortex and hippocampus, and altered functional connectivity within the default mode network.
Conclusion: GDM is associated with long-term cognitive impairment in mothers, possibly mediated by structural and functional brain changes. These findings highlight the importance of early identification and management of GDM to mitigate potential long-term cognitive consequences.
Post-COVID condition: Pulmonary or systemic, reversible or irreversible?
Authors: Laban Marija , Škodrić-Trifunović Vesna
Published: December 2023

During the COVID-19 pandemic, many patients were completely recovered, and about 30% of patients had prolonged symptoms, independent from the severity of their clinical picture of the COVID-19. There is no correlation between severe acute COVID and severe post-COVID syndrome. According to the NICE 2020 recommendations, the term long COVID includes symptomatic COVID-19 (period 4-12 weeks after acute disease) and post-COVID-19 syndrome. According to the WHO post-COVID-19 syndrome is a condition in persons with a history of probable or confirmed COVID infection, usually 3 months from the onset of COVID-19, with symptoms lasting at least 2 months, that cannot be explained by an alternative diagnosis. Intolerance to physical exertion, experiencing breathing difficulty and neuropsychiatric disorders are the most common and the longest lasting difficulties. Most common respiratory post-COVID manifestation is persistent dyspnea, while persistent pulmonary fibrosis was extremely rare. In almost half of patients who have had severe COVID pneumonias, there was no absolute correlation between pulmonary function disorders and thoracic CT images, and disorders kept persisting after complete radiographic regression. Dominant manifestation of these disorders is reduced lung diffusion capacity for CO (TLCOc, KCOc), while spirometry values are mostly normal. Pulmonary thromboembolism, myocarditis, anxiety-depressive disorder, forgetfulness and hair loss are some of the serious post-COVID complications. A significant number of patients need physical rehabilitation.
The implications of oxidative stress in long COVID pathogenesis
Authors: Ćorić Vesna
Published: December 2023

As far as clinical presentation is concerned, following an episode of acute sickness, the SARS-CoV-2 infection may lead to the development of a number of complications known as post-acute sequelae of SARS-CoV-2 infection (PASC). The definition of PASC, as well as its estimated prevalence evolved over the course of time and acquired knowledge. Although COVID-19 was initially characterized as an acute respiratory illness, convalescents frequently report diverse clinical manifestations related to several organ systems, referred to as long COVID. However, the fundamental molecular mechanisms that are responsible for the incapacitating symptoms, occurring in patients with long COVID, remain largely unexplained at this time. From a molecular medicine point of view, one of the proposed postulates favors the impaired redox balance, which may serve as a central hub responsible for mechanisms disturbing the cellular homeostasis, innate immune response and metabolism. This review will try to tackle the current knowledge about the underlying mechanisms comprising the proposed interplay of the disturbed redox balance and inflammation, that may potentially contribute to the occurrence of tissue or organ damage that is linked with COVID-19, as well as the eventual manifestation of symptoms observed in individuals with long COVID. One might assume that in certain individuals, there are mechanisms that may dominate over others. Genetic variability may offer some answers - especially in the case of polymorphisms occurring in genes that encode for antioxidant proteins and enzymes.
Epidemiology of post-COVID syndrome

Published: December 2023

As per the World Health Organization's (WHO) definition, post-COVID syndrome or long COVID refers to the persistence or emergence of new symptoms three months after the initial infection with the SARS-CoV-2 virus (severe acute respiratory syndrome coronavirus 2), and lasting for a minimum of two months, while excluding alternative diagnoses. The precise mechanisms responsible for the development of long COVID-19 symptoms have yet to be fully understood. The prevalence of post-COVID syndrome exhibits considerable variation , mostly influenced by factors like as study design, study population, and the specific case definition employed in the study. Based on some estimations, a minimum of 10% of those exhibiting a severe clinical manifestation of SARS-CoV-2 viral infection are likely to have post-COVID syndrome. This condition is characterized by multisystemic involvement, presenting a diverse spectrum of symptoms that impact several bodily systems, including but not limited to the respiratory, cardiovascular, musculoskeletal, neurological systems and skin. The prevailing manifestations of prolonged COVID-19 encompass fatigue, dyspnea, and cognitive impairment. Nonetheless, a spectrum of over 200 distinct symptoms have been documented, which can significantly impede the day-today capabilities of those afflicted with the condition. Based on data derived from both the United States and Europe, it has been shown that the incidence of long COVID syndrome has a greater frequency among the female population and individuals afflicted with chronic conditions. Considering the global prevalence of individuals affected by the SARS-CoV-2 virus, it is imperative to conduct ongoing epidemiological surveillance to gain a consistent understanding of the current situation. Additionally, it is crucial to perform research, primarily utilizing representative population samples, to enhance our understanding of risk factors and identify potential preventive measures. This knowledge would also contribute to the identification of population groups with a higher susceptibility to the onset of post-COVID syndrome, which holds significant value in comprehending the enduring consequences of the COVID-19 pandemic.
Development of long COVID as a consequence of the complex relationship between Epstein-Barr virus and our immune system
Authors: Banko Ana
Published: December 2023

Introduction: The pathophysiological development of long COVID (LC) is still insufficiently known. However, post infection fatigue syndromes were seen before, among other pathogens including Epstein-Barr virus (EBV). Considering EBV reservoir in COVID-19 patients, this review aims to present current knowledge related to EBV role in development of LC and with the potential diagnostic utility. EBV infection: Following the primary lytic infection of epithelial oropharyngeal and nasopharyngeal cells EBV establishes a very complex mechanism of lifelong survival in B cells. Latent infection with occasional viral reactivations constantly challenges the host's immune response. In individuals with immune imbalance including COVID-19, it could drive long-term consequences. EBV and COVID-19: The activity of EBV has been shown as the most prevalent human herpesvirus infection in COVID-19 population (41%). Correlation between lymphocytopenia-induced disability to remove the EBV, increases in EBV DNA viremia and COVID-19 complications have also been reported. EBV and long COVID: The positivity of EBV DNA during acute SARS-CoV-2 infection predicted the presence of symptoms up to 60 days after COVID-19. Association between EBV infection and symptoms such as brain fog, fatigue, arthralgia and skin rashes have been also described in post infection sequelae ME/CFS. Anti-EBV early antigen-diffuse (EA-D) IgG antibodies were detectable among two-thirds of respondents experiencing LC. Increases in anti-EBNA1 IgG levels analyzed months following COVID-19 onset in convalescent LC population could serve as a potential marker of EBV reactivation at the time of acute SARS-CoV-2 infection. Some authors also managed to show anti-EBV viral capsid antigen (VCA) IgM seropositivity in half of COVID-19 patients indicating of either coinfection or EBV reactivation. Conclusion: As a multisystemic illness, LC is without a defined spectrum of diagnostic and treatment options. Whereas EBV reactivation alone or together with other risk factors drives LC symptoms, further prospective studies involving different cohorts and tissue reservoirs are necessary to understand underlying biological mechanisms.
Advancing semantic and pragmatic theoretical frameworks through an analysis of Taylor Swift's "Look What You Made Me Do"
Authors: Diko Mlamli
Published: December 2023

Semantics and pragmatics, as theoretical frameworks, continue to prove their appropriateness in the examination of literary texts and conversations, as well as in songs and music. This denotes that the two theoretical frameworks cannot solely be constricted within the parameters of general linguistics; instead, they are applicable to other disciplines or subject areas. In view of this fact, this article aims to uncover the covert meanings in Taylor Swift's "Look What You Made Me Do" lyrical song. To do this, semantic and pragmatic theoretical frameworks are applied, while the song itself is acknowledged as a primary source of data. The objective of this article is to demonstrate the development of semantics and pragmatics, as theoretical perspectives, and the ways in which meaning can be explicated using these theoretical perspectives in the chosen song and other areas of interest. Ultimately, the overall objective is to demonstrate how words, phrases and sentences may be understood differently by language users. The results and discussions validate that Taylor Swift uses different linguistic techniques, as well as metaphorical expressions to communicate her message to her audience. Nevertheless, such abilities of this singer and songwriter may not always be clear to everyone, hence the necessity to apply semantic and pragmatic theoretical lenses. The closing remarks underline the importance of continuing to develop the two theoretical perspectives beyond the limitations of general linguistics. In addition to this, the closing remarks underscore the synergetic relationship that exists between language and music.
Needlework and Narration: The Case of Margaret Atwood's "Alias Grace"
Authors: Torrejón-Tobío Celia
Published: December 2023

This article explores the main character in Margaret Atwood’s novel Alias Grace (1996) in terms of the semiotics of the textile and its corresponding feminine implications. The main hypotheses enunciated concern, on the one hand, the possibilities of narrativity that this symbol brings about (particularly for dissident discourses) and, on the other hand, the dissipation of the conceptual and representational boundaries of the textual and the textile. Furthermore, this study suggests a revision of the imaginary traditionally associated with the feminine spheres and an approach to these spaces as places of resistance that have arisen in the midst of silencing, captivity, or marginalisation.

Published: December 2023

Este artículo presenta un análisis comparativo del tratamiento dado a la producción y la comprensión escritas en diez manuales de español LM (ESO y Bachillerato) y L2/LE (niveles intermedio y avanzado). El estudio se detiene en si estas destrezas están interrelacionadas en actividades complejas y con modelos variados, y cómo capacitan para una ejecución competencial integrada pues su elección determina el proceso de enseñanza y aprendizaje. Concluimos que es así en el caso de EL2/LE, campo en el que actividades y tareas globales están relacionadas con todos los ámbitos y competencias comunicativos para ejercitar las destrezas de modo secuenciado e interdependiente. Este proceder solo aparece en los manuales de ELM del Proyecto Galaxia. A pesar de que todos ellos están orientados hacia el método comunicativo, en la lengua materna predominan la teoría y descripción exhaustiva del sistema lingüístico y las actividades de reflexión gramatical, sin atender a su finalidad práctica.
Metáfora y poesía a través de los sueños en "Mármol", drama de lo sublime y de lo onírico: Marina Carr, ¿sucesora de Calderón de la Barca?
Authors: Osuna Osuna M.ª Teresa
Published: December 2023

En las dos primeras décadas del siglo XXI la escritora irlandesa Marina Carr ha destacado a nivel internacional con una producción dramática singular. Por el simbolismo y la naturaleza onírica de algunas de sus obras, ha sido reconocida como una de las sucesoras del dramaturgo español Pedro Calderón de la Barca. Marble (Mármol) es una extraordinaria obra de Marina Carr sobre la experiencia humana en torno a los sueños. ¿Sigue este drama la estela de La vida es sueño? En ambas composiciones, a través de la imagen se exploraría la vida como un sueño en aras de la libertad y la dignidad del hombre. Los elementos metafóricos y el lenguaje poético reparan el modelo existencial y ético elegido en nuestra trayectoria de vida. Carr cubre nuestros sueños con mármol cuando ya resultan compactos, irrompibles y están perfectamente pulidos porque reflejan una existencia perfecta. Presenta los sueños como reflexión sobre una segunda oportunidad de alcanzar el éxito y la liberación personal, reviviendo la nostalgia y alcanzando lo sublime frente a la fatalidad y lo trágico de la realidad.
Impacts of chemical reaction, thermal radiation, and heat source/sink on unsteady MHD natural convective flow through an oscillatory infinite vertical plate in porous medium
Authors: Saikia Dibya Jyoti , Ahmed Nazibuddin
Published: December 2023

The main objective of this exploration is to analyze the effects of heat source/sink, chemical reactions, and radiation on the unsteady free convective flow through a porous medium using an infinitely oscillating vertical plate. The Laplace transformation tactics is utilized to solve the governing equations for concentration, energy, and momentum. The simulation results demonstrate that the chemical reaction parameter dwindles both primary and secondary velocities. It has been noted that an upsurge in heat generation (heat source) enhances the temperature field, while a decrease in heat absorption (heat sink) leads to a reduction in the temperature field. Furthermore, the radiation parameter causes a drop in both temperature and velocity patterns. The equation for skin friction is derived and presented graphically, and 3-dimensional surface plots are provided to depict the Nusselt number and Sherwood number. Additionally, graphical illustrations are employed to showcase the influence of various non-dimensional variables on concentration, temperature, and velocity patterns.
Tribological properties of DLC and GLC coating for automotive engine components application under lubrication
Authors: AL-SAMARAI Riyadh A. , AL-DOURI Y.
Published: December 2023

Modern automotive designs are needed to increase mechanical and thermal loads that have longer lifespans and are lighter. The power transmissions and motors often use low-friction hard coatings to prevent wear and reduce friction. The Cr-doped graphite-like carbon method is employed for evaluating coating friction and responses to chromium-doped graphite-like carbon (Cr-GLC) under lubrication. Cr-GLC coatings and chromium-doped diamond-like carbon (Cr-DLC) coatings are arranged using physical vapor deposition (PVD) and plasma-enhanced chemical vapor deposition (PECVD), respectively. The results have demonstrated in comparison to the dry friction coefficient, the friction coefficient under lubrication conditions has been reduced by 40%. Due to its excellent frictional physicochemical properties and compact microstructure, Cr-DLC has an optimum tribological resistance that is significantly higher than that of Cr-GLC. Viscosity, corrosivity, and coating microstructure are used to measure the impact of composite elements. The most ideal characteristics of the Cr-GLC coating are attributed to the non-reaction of additives in oil with friction surfaces.

Lo escrito en este artículo pretende dar una mirada crítica al valor artístico y literario que se le ha otorgado a las expresiones orales populares en Colombia a partir de algunos aspectos importantes; el primero es que a este tipo de expresiones culturales, por ser referidas dentro de lo que denominamos folclor, eran consideradas vulgares y poco dignas por el uso de un lenguaje menos “hermoso”; la segunda son las políticas culturales que infieren en Colombia frente e estas producciones artísticas que dotan de identidad a la cultura del país.
Trozos de mi pensamiento, a propósito de Roberto Juarroz
Authors: Alejandra Valbuena Prada Alejandra
Published: December 2023

Hago apertura a este texto navegando por mi modo de ver y sentir las letras, hay palabras que son livianas, transitan desapercibidas y no inciden en mí, de hecho, se escurren entre mi cuerpo, pero, hay letras que me tocan e incluso me enardecen, siento que tienen filo y me hieren, qué tan frágil puedo ser cuando la poesía rosa mi piel; pienso también que las palabras son a veces como almas perdidas, andan por el mundo buscando un cuerpo para poseerlo y adentrarse tan en el fondo que logran sacar nuestro lado más sensible y permutan allí.

¿Para qué leemos literatura? Notas rápidas, para leerlas en calma
Authors: Silgado Ramos Alex
Published: December 2023

¿Para qué leemos literatura?, la pregunta me la hacen como quien, en vista de tu descuido, te arroja a la cabeza una piedra filosa para ver si te despiertas. El golpe es certero y consigue descalabrarme. Sin embrago, no despierto aún. Luego, encuentro el momento y me arrojo, entonces, con cierto sosiego, a mi viejo cuaderno de notas e intento dibujar algunas palabras que casi son impresiones; imágenes, quizá, que no tienen el tamaño de razones conscientemente elaboradas y sopesadas, sobre esta inquietud.

As a therapeutic target, protein tyrosine phosphatase 1B (PTP1B) has received considerable attention for the treatment of diabetes mellitus. A QSAR study using substituted monocyclic and polycyclic thiophene derivatives, recently reported as potent PTP1B inhibitors, was carried out. More than 60 physicochemical descriptors were calculated which underwent rational selection before their use in derivation of QSAR models. Statistically significant equations were generated using multiple linear regression analysis. External validation of the derived models with test set compounds proved good predictability of the models. Interpretation of the results revealed lipophilicity as a key regulatory feature which affects PTP1B inhibition along with several electronic and steric parameters. The study provides an important platform upon which novel rationally designed molecules can be synthesized with cautious optimism.

Neue Realitäten im Landtag
Authors: Goldhammer Michael
Published: December 2023

Den Ruf als „härtestes Parlament Deutschlands“ hatte sich der Landtag in Wiesbaden schon lange vor dem Einzug der AfD erworben. Offenbar haben die Verhältnisse im Wiesbadener Stadtschloss in den letzten Jahren aber eine andere Qualität erreicht. Jedenfalls wird man so die „dringliche“, parteiübergreifende Gesetzesinitiative, bestehend aus CDU, Bündnis 90/Die Grünen, SPD und FDP, verstehen dürfen. Sie trägt den Namen Demokratiepaket, ist offensichtlich gegen die AfD richtet und wurde am 12.12.2023 noch schnell vom alten Landtag verabschiedet, um für die neue Legislatur gerüstet zu sein. Parlamentarismus kennt keinen Endzustand, sondern ist Sisyphusarbeit.
