Unsupervised machine learning based anomaly detection in high frequency data: Evidence from cryptocurrency market
(Johar Education Society Pakistan, 2025) Latif, Muhammad Nouman; Kaplan, Muhittin; Khan, Asad ul Islam; Yönetim Bilimleri Fakültesi, İktisat Bölümü
The rapid integration of cryptocurrencies into the global financial ecosystem has introduced unprecedented challenges in market surveillance, risk management, and anomaly detection. While conventional statistical models such as ARIMA (Autoregressive Integrated Moving Average) and GARCH (Generalized Autoregressive Conditional Heteroscedasticity) have been widely used for anomaly detection, their reliance on assumptions of normality and stationarity often fails to capture the complexities of high-frequency, non-linear cryptocurrency trading. Furthermore, traditional risk metrics including down-to-up volatility, negative conditional skewness, and relative frequency may overlook short-term anomalies due to data aggregation limitations.In order to address these issues, this paper proposes machine-learning model for detecting anomalies in cryptocurrency markets using Jupyter Notebook. We compare four advanced unsupervised machine learning models, i.e, Density-Based Spatial Clustering of Applications with Noise (DBSCAN), Isolation Forest (iForest), One-Class Support Vector Machine (OC-SVM), and Local Outlier Factor (LOF) for anomaly detection by using Monte Carlo simulations. The findings indicate that DBSCAN has the highest precision (79.7%) with the fewest false positives, making it ideal for supervisory monitoring. However, the high false positive rates of OC-SVM and Isolation Forest limit their use. By using data of six well-known cryptocurrencies at three different temporal resolutions (daily, hourly, and 15-minute) the performance of these four unsupervised learning techniques also examined and confirmed that the anomalies identified by DBSCAN are also consistent with the other three methods. Additionally, for robustness of results, we use UpSet Plots to incorporate the shared anomalies and found across the three unsupervised learning methods. Number of anomalies also depends on the volatility and time interval of cryptocurrencies, more volatile / high frequency more anomalies. The study presents sound methodological approach for facilitating financial monitoring and mitigating risks in the cryptocurrencies market, and provides useful information for market players, analysts and policymakers. These results emphasize the importance of choosing algorithms based on specific surveillance targets to promote greater stability in digital asset environments.
Habermas as an ethnic thinker Par Excellence: On critique, Palestine and the role of intellectuals
(Routledge, 2025) Ahmad, Irfan
Taking Habermas’ 2023 statement on Palestinians-Israel as the point of entry, this article examines his concept of critique. Against the dominant view of him as a philosopher of ‘universalism’ and ‘critical rationality,’ my thesis is that Habermas is an ethnic thinker, for, his ideas of critique and universalism unidirectionally rest on ‘to all’ rather than ‘from all.’ Consequently, it is missionary and borders on Islamophobia, particularly after 9/11. I show how Habermas’ denial of Palestinians’ genocide and his unqualified support to ‘Israel's right to exist’ as integral to Germany's ‘democratic ethos’ is neither an ample departure from his participation in the Hitler Youth nor from his understanding of the Enlightenment-modernity but largely their offshoots. I also juxtapose Habermas’ role as a public intellectual with that of Imam Malik (d. 795) who chose to be flogged rather than parrot unjust language of power elites. I conclude with three broad implications this article has in the field of teaching in higher education.
Exploring covert diplomacy in peace negotiations
(Cogitatio Press, 2025) Kaya Uyar, Sümeyye
Armed groups seeking political or territorial change frequently challenge governments, leading to protracted armed conflicts. However, not all conflicts are resolved through decisive military victories. As a result, states have increasingly turned to secret negotiations as an alternative means of engagement. While secrecy can facilitate diplomatic flexibility, its effectiveness depends on the credibility of the government’s commitment to cooperation. This study examines how the selection of government representatives in secret negotiations influences rebel group behavior and the likelihood of cooperation. Drawing on costly signaling theory and research on secrecy in diplomacy, this study argues that the level of government representation in secret negotiations serves as a key mechanism for signaling credibility. Specifically, high‐level representatives function as costly signals, reassuring rebels of the government’s seriousness and increasing the likelihood of cooperation. By contrast, low‐level representatives provide strategic deniability but fail to generate trust, making negotiations less effective. This dynamic is particularly relevant in democratic settings, where governments face domestic audience costs if secret negotiations are exposed. To test these claims, the study employs a large‐N quantitative analysis of secret negotiations between democratic governments and rebel groups. The findings indicate that secret negotiations led by high‐level representatives significantly reduce rebel violence. In contrast, those conducted by low‐level representatives fail to establish credibility and do not contribute to de‐escalation. These results highlight the importance of credibility, the choice of representatives, and secrecy in conflict resolution, with implications for backchannel diplomacy and long‐term cooperation outcomes.
[Book Review]: "The Biblical trinity: Encountering the Father, Son, and Holy Spirit in scripture (kitap incelemesi)"
(Çanakkale Onsekiz Mart Üniversitesi, 2025) Dingyadi, Hassan Usman
The doctrine of the Trinity has remained central yet contested within Christian theology, owing to its implicit rather than explicit articulation in Scripture. Brandon D. Smith’s The Biblical Trinity: Encountering the Father, Son, and Holy Spirit in Scripture (Lexham Press, 2023) represents a contemporary attempt to recover a biblically grounded and pastorally accessible account of Trinitarian theology. This review situates Smith’s work within the broader tradition shaped by figures such as Augustine, Aquinas, Barth, and Swain, and examines its methodological commitments, theological contributions, and limitations. Smith advances four interpretive principles—Nature, Relations, Inseparable Operations, and Hypostatic Union—while employing a canonical approach that places New Testament texts in dialogue with the Old Testament to trace the progressive unveiling of the Triune God. His analysis of selected passages demonstrates clarity of exposition and a distinctive integration of theological reflection with devotional practice, framing the Trinity not as an abstract doctrine but as a summons to worship. Nevertheless, the work is marked by certain methodological constraints, including a reliance on biblical texts at the expense of historical and systematic engagement, occasional oversimplification of technical concepts, and an assumption of prior theological literacy. Despite these shortcomings, The Biblical Trinity offers a significant contribution to contemporary Trinitarian studies by rendering complex theological concepts accessible and by highlighting the practical and devotional dimensions of the doctrine. It thus provides a useful resource for students, researchers, and practitioners seeking a deeper understanding of the Trinity’s biblical foundations and theological significance.
[Book Review]: "Restoring the sacred in psychotherapy"
(Halil EKŞİ, 2025) Sikander, Yaqeen
The aim of this paper is to review the book Applying Islamic Principles to Clinical Mental Health Care - Introducing Traditional Islamically Integrated Psychotherapy, Edited by Hooman Keshavarzi, Fahad Khan, Bilal Ali, Rania Awaad and others. The book fills a huge void by creating an integrative framework that incorporates theoretical explanations along with practical applications and interventions of Islamic psychotherapy.
