Öğe Türü: Yayın , The Dynamic Linkages Among Artificial Intelligence, Sustainable Energies, Commodities, and Islamic Investments: Evidence from a Multivariate GARCH Model(Springer, 2026) Uluyol, Burhan; Yumuşak, İbrahim Güran; Rasheed, Jawad; Uluyol, Burhan; Yumuşak, İbrahim Güran; Rasheed, Jawadhis study aims to contribute to optimal portfolio theory by examining the dynamic correlations between Artificial Intelligence (AI) and other alternative investments. Optimal portfolio theory focuses on maximizing returns while minimizing risk through efficient asset allocation methods. Drawing on the First Trust Nasdaq Artificial Intelligence and Robotics ETF as a representative proxy, the research investigates to what degree AI-related assets behave in an interdependent manner with other types of alternative investments. To analyze these dynamic correlations, the study employs the Dynamic Conditional Correlation Generalized Autoregressive Conditional Heteroskedasticity (DCC-GARCH) model. The study uses time-series data from March 1, 2019, to January 27, 2025. This econometric model allows the estimation of evolving correlations and volatilities across AI assets and other investments. Our findings indicate that crude oil provides diversification benefits to all asset classes under study, and all types of investors can obtain diversification benefits from Islamic investments, except for investors in Artificial Intelligence ETFs. Furthermore, the Artificial Intelligence ETF can provide diversification benefits to all types of investors under study, except for Islamic investment-based investors. This study incorporates the Artificial Intelligence ETF into a research framework encompassing sustainable energy, commodities, and Islamic investment—a combination rarely explored in prior research—and provides guidance on portfolio diversification strategies for interested parties. © The Author(s), under exclusive licence to Springer Nature Singapore Pte Ltd. 2026.Öğe Türü: Yayın , Arsa Payı Karşılığı İnşaat SözleşmesininKurulması, Şekli ve Görünüm Şekilleri(Kocaeli Üniversitesi, 2025) Taşçı, Ahmet Fatih; Taşcı, Ahmet FatihBu çalışma, arsa payı karşılığı inşaat sözleşmelerinin hukuki niteliğini, kuruluşunu, şekil şartlarını vegörünüm şekillerini incelemektedir. Arsa payı karşılığı inşaat sözleşmesi, eser sözleşmesi ile taşınmazsatışı sözleşmesinin birleşimi niteliğinde olup, isimsiz (atipik) ve çifte tipli karma sözleşmeler kapsamındadeğerlendirilmektedir. Bu sözleşme türünde, arsa sahibi belirli arsa paylarını yükleniciye devretmeyitaahhüt ederken, yüklenici de arsa üzerinde inşaat yapmayı ve belirlenen bağımsız bölümleri arsasahibine teslim etmeyi üstlenmektedir. Çalışmada, bu sözleşmelerin resmi şekle tabi olduğu ve TapuKanunu’nun 26. maddesi ile Noterlik Kanunu’nun 60. maddesi gereğince noterde resen düzenlemeveya tapu sicil müdürlüğünde düzenleme şeklinde yapılmasının zorunlu olduğu vurgulanmaktadır. Şekilşartına uyulmadan düzenlenen sözleşmeler geçersiz sayılmaktadır. Ayrıca, sözleşmenin tapuya şerhedilmesi hâlinde, Şerhin eşyaya bağlı borç ve munzam etkisiyle yüklenicinin hakları üçüncü kişilere karşıkorunacaktır. Çalışmada ayrıca, arsa payı karşılığı inşaat sözleşmelerinin üç temel uygulama modeliele alınmaktadır: (i) arsa paylarının baştan veya tamamen devredildiği model, (ii) inşaatın ilerlemedurumuna göre kademeli devir yapılan model ve (iii) taşınmaz satış vaadi ile yüklenicinin inşaat yapımınıtaahhüt ettiği model. Sonuç olarak, bu sözleşmelerin hukuki güvence altına alınabilmesi için resmi şekilşartlarına uyulması ve tarafların edimlerini net bir şekilde belirlemesi gerektiği vurgulanmaktadır.Öğe Türü: Yayın , مشروعية الصكوك المستندة إلى الذهب من خلال الاقتراض الحكومي في تركيا: دراسة فقهية في ضوء بيع الوفاء وبيع الاستغلال(Kahramanmaraş İstiklal Üniversitesi, 2025) Kuluç, Abdullah; Almoustafa, Bahjt Mouhamd; Kuluç, Abdullahشهدت السنوات الأخيرة توسّعًا ملحوظًا في استخدام صكوك الإجارة ضمن منظومة الاقتصاد الإسلامي، ولا سيّما الصكوك المستندة إلى الذهب، التي طُرحت على المستثمرين بوصفها أدوات تمويلية بديلة يُدَّعى خلوّها من الربا. يهدف هذا البحث إلى تقويم المشروعية الفقهية لصكوك الإجارة المبنية على الذهب المستخدمة من خلال الاقتراض الحكومي في تركيا، من خلال تحليل بنيتها العقدية وآليات إصدارها ونتائجها العملية، وبيان علاقتها بعقدي بيع الوفاء والبيع بالاستغلال وما يرتبط بهما من أحكام الرهن والربا في الفقه الإسلامي، ولا سيّما في إطار المذهب الحنفي. وتتمحور إشكالية الدراسة حول مدى انسجام هذه الصكوك، في تطبيقها العملي، مع الضوابط الشرعية للعقود المالية، وما إذا كانت تمثّل بديلًا شرعيًا حقيقيًا عن السندات الربوية أم تكييفًا فقهيًا لآليات الاقتراض التقليدي. ولتحقيق ذلك، اعتمدت الدراسة منهجًا تحليليًا وصفيًا ذا بُعد فقهي تطبيقي، من خلال وصف هيكلة الصكوك وإجراءات إصدارها بالاستناد إلى البيانات الرسمية الصادرة عن الجهات التركية المختصة، ثم تحليلها في ضوء القواعد الفقهية وقرارات المجامع الفقهية المعاصرة، ولا سيّما هيئة المحاسبة والمراجعة للمؤسسات المالية الإسلامية (AAOIFI) ومجمع الفقه الإسلامي الدولي. كما تناول البحث البنية القانونية والطبيعة الفقهية للشخصية الاعتبارية للشركة ذات الغرض الخاص لإصدار الصكوك (Hazine Müsteşarlığı Varlık Kiralama Şirketi)، وأجرى مقارنة بين صكوك الإجارة المستندة إلى الذهب وسندات الذهب المطروحة بالتزامن معها. وتخلص الدراسة إلى وجود إشكالات فقهية وقانونية مؤثرة في تقويم مشروعية هذه الصكوك، مع تقديم مجموعة من التوصيات الهادفة إلى تعزيز انضباطها الشرعي وتوجيه تطويرها بما ينسجم مع مقاصد الشريعة.Öğe Türü: Yayın , AI in energy management: the market view(The Institution of Engineering and Technology, 2025) Shannak, Sa'd; Alashgar, Deeb; Migdad, Abdalrahman; Mıgdad, Abdalrahman M.I.This chapter examines the impact of artificial intelligence (AI) on energy management. A lot of attention was paid to the market and emerging technologies and their potential in addressing global problems in energy. In the course of such energy-related troubles as energy demand, environmental issues, and the urgency of switching to renewable resources, AI appears to be the spark in the radical and sustainable transformation of the energy sector. A particular emphasis has been made on the most significant players in this industry, ranging from established energy firms to nimble new entrants; all of them apply AI in making energy use and its predictive maintenance and automation of the grid even smarter. We demonstrate these transformations through a number of practical examples, not only do the new technologies bring permanent changes in energy operations, but they are also transforming the way utilities do business with their customers. There are however difficulties associated with the implementation of AI in the energy market such as data security, proper infrastructure, and human resources. However, the benefits of embarking on this journey are enormous. To be sure, a successful deployment of energy AI technologies can take us to a future world that is green and efficient for an individual, communities, and the society at large.Öğe Türü: Yayın , Economic Devastation: The Impact of the Israeli War on Gaza’s Work and Economic Growth(Springer Nature, 2025) Migdad, Mohammed; Migdad, Abdalrahman; Migdad, Isra; Hassoun, Abdo; Mıgdad, Abdalrahman M.I.This chapter examines the severe economic consequences of the recent war on Gaza, focusing on Sustainable Development Goal 8 (SDG 8), which aims to achieve inclusive economic growth and decent work for all. This genocidal war has caused extensive job losses, destruction of industries, and widespread poverty, while the devastation of infrastructure has undermined economic stability. Movement restrictions, the blockade, and military operations have disrupted trade and humanitarian aid, further worsening economic conditions. Unemployment has surged, particularly among youth and women, while unsafe working conditions and the rise in child labor reflect dire socioeconomic conditions. The destruction of businesses, along with educational and vocational facilities, has severely hindered skill development and undermined long-term economic prospects. However, amidst the devastation, inspiring examples of resilience and innovation, such as youth-led entrepreneurial ventures and community-driven initiatives, demonstrate the potential for recovery and economic renewal. This chapter highlights the urgent need for sustainable peace and international interventions to rebuild Gaza’s economy. Strategies for recovery, including infrastructure reconstruction, job creation, and fostering local entrepreneurship, are explored, underscoring the importance of restoring economic stability and achieving the inclusive and sustainable development envisioned by SDG 8.
