Application of Islamic Economic Principles to Indian Financial Sectors: Prospects and Challenges
No full textEconomic system is the integral part of every social system. Globalized economy introduces three types of economic systems which are private, public, and mixed ownership. Despite people take part of these three systems in major countries, the frequent fi nancial crunches and questioning of reliability on conventional fi nancial system, many countries try to bring an alternative fi nancial system that can consistently work on transparency and accountability in all economic spheres. Islamic economic system is solution of such thinking due to its success and safety operations in all practicing countries.
In Gulf Cooperation Council countries, all Islamic banks are performing triumphantly which include 25 banks. Its products and services are based on profi t loss sharing mechanisms which adhere to the principles Islamic shariah. Mudaraba, Musharaka, and Murabaha are the main instruments which are usedmostly in all fi nancial sectors. The present system of commercial banking is based on minimization of risk and maximization of profit. On the contrary, Islamic fi nancing is performed as social fi nancial system so as it is highly attracted by non -Muslim customers also for them that stands as safe and connected to real economy. Even Islamic fi nance is at adolescence stage in its growth in India, its applicability is well subjected overall the Indian fi nancial services such as mutual fund, microfi nance, non-banking financial company (NBFC) based fi nancial system, and venture capital. The recent launching of Cheraman Financial Services Limited and some movements like SBI Shariah mutual funds elevate this study to introduce an alternative system to those people who suffocate in the knot of Interest. India has approximately 175 million Muslims, they are highly to be excluded from access to banking productsand services due to absence interest free fi nancial services.
The gap is prevailing by the lack of mediatory functions such as Islamic financial sectors and other investment institutions. The present RBI regulations such as Repo rate, statutory liquidity ratio, and cash reserve ratio, constrain to practicing Islamic banking in India. However, excessive demand and working forms such as NBFC, Non-Government Organization, and Nidhi, show the ways to applying Islamic economic system in the Indian scenario too. So, the presentstudy focuses to fi nd out feasible models for implementing Islamic economic principles and its practical products and services in India.
It is an attempt to analyze the prospects, challenges, and drawing solutions to regulatory problems. It also illustrates basic Islamic shariah principles, the Indian financial system with reference shariah based fi nancial services. To do research, exploratory method will be used and data will be collected on secondary basis

No full textLisansüstü Eğitim Enstitüsü, Temel İslam Bilimleri Ana Bilim DalıÇalışmamız Arap dilinin Osmanlı dönemi öğrenim ve öğretim tarihi içinde önemli bir yer tutan Osmanlı medreselerinde yetişmiş çok yönlü bir âlim olan Muhammed el-Medenî'nin Risale fî beyâni mâ vaka' min'el-evhâmi fî sıhâhi'l-Cevherî adlı eserinin tahkikli neşrini ortaya koymayı hedeflemektedir. Muhammed el-Medenî Osmanlı döneminde yaşamış, yazdığı eserlerden çok yönlü bir âlim olduğu anlaşılan ve o dönemde oldukça meşhur olmuş bir âlimdir. Bir süre Medine'de ikamet ettiği için bu nisbeyi almıştır. Lugat alanında yazılmış olan, Fîruzâbâdî'nin el-K?mûsu'l-muhit adlı eserinde Cevherî'nin Tacu'l-luga adlı eserine yöneltmiş olduğu eleştirileri bir araya getiren, zaman zaman Fîruzâbâdî'nin Cevherî'ye yöneltmiş olduğu eleştirilerinde haklı ya da haksız olduğuna dair Muhammed el-Medenî'nin görüşlerini de ifade ettiği bu eser luğat alanında iki temel eser olan bu iki kitap üzerinde yapılan bir çalışma olması hasebi ile önemlidir. Çalışmamızın giriş bölümünde; luğat ilmi hakkında tarihi ve teknik bilgi verdikten sonra luğat alanında Arap âleminde Türkiye'de ve Batı Dünyasında yapılmış çalışmalara kısaca yer verilmiştir. Birinci bölümünde, Muhammedd el-Medenî, Fîruzâbâdî ve Cevherî'nin hayatı hakkında bilgi verildikten sonra Çalışmamıza konu olan Risale fî beyâni mâ vakaa min'el-evhâmi fî sıhâhi'l-Cevherî adlı eser tanıtılmış, eserin Müellif'e aidiyeti konusu, eserin mevcut nüshası tanıtılmış ve edisyon kritik çalışmamızda takip edilen yöntem hakkında bilgi verilmiştir. ikinci bölümde eserin tahkikli neşri yapılmıştır.Our study aims to make a critical edition of Risale fî beyâni maâ case 'min'el-evhâmi fî Sıhâhi'l-Cevherî by Muhammad al-Madani, a versatile scholar who grew up in Ottoman madrasas, who had an important role in the history of education and teaching of the Arabic language throughout the Ottoman history. Muhammad al-Madani was a scientist who lived in the Ottoman period, from whose works one can understand that he is a versatile scholar and who became very famous at the time. He received this Arabic name since he lived in Medina for a while. The work, which is categorized as a dictionary, provides a compilation of the criticisms that Fîruzâbâdî made in his work "el-K?mûsu'l-muhit" with reference to Cevherî's "Tacu'l-luga" and occasionally, he gives his disagreeing and agreeing opinions on the criticism. It is significant in the sense that it combines the two fundamental works in the field of dictionary writing. In the introduction of our study, after giving information about the historical and technical knowledge about Islamic lexicography, the studies conducted in the Arabic and Western world, and Turkey in the field of Islamic lexicography is briefly mentioned. In the first part, after giving information about the lives of Muhammed al-Madani, Fîruzâbâdî, and Cevherî; the subject of our study, Risale fî beyâni mâ casea min'el-evhâmi fî Sıhâhi'l-Cevherî was introduced and the ownership of the work to the author is discussed. In the second part, the current copy of the work is introduced and in our critical edition study, the information about the methodology followed in the study is given. In the third chapter, a critical edition of the work was included
Continuity and change: a comparative study of Nigeria's foreign policy under the military regimes, 1966-1979, 1985
No full textThe impetus for this study came from the debate in Nigerian academic circles concerning Nigeria's foreign policy under the military regimes. The focus of that debate has been on whether Nigeria's foreign policy under the Muhammed/Obasanjo regime was characterized with continuity or change from that of its predecessor regime the Gowon regime. This study examined the foreign policy behavior of both military regimes on the key issues of decolonization, apartheid South Africa, the quest for economic independence and non-alignment. On the issue of decolonization, the analysis focused on Nigeria's foreign policy behavior relevant to Angola, Namibia and Zimbabwe. The discussion on the issue of Nigeria's quest for economic independence focused on her role in the formation of ECOWAS, the development of the Lome' Conventions, and her contribution to the development of the Law of the Sea Convention. The study also looked (with the aid of a model) at the factors that influenced Nigeria's foreign policy. The study concludes that: 1. Nigeria's foreign policy under the Muhammed/Obasanjo regime was characterized with both continuity and change from that of the Gowon regime; 2. the changes both in substance and style that were evident in the former's foreign policy behavior from the latter's were mostly manifested in its foreign policy relevant to the issues of decolonization and the liberation of South Africa; 3. continuity pervaded the efforts of both regimes in their quest for Nigeria's economic independence; 4. Nigeria's structural dependence on the west was contributory to the stultification of her pronounced policy of nonalignment; 5.the differences in both regime's foreign policies were more the product of the idiosyncrasies of the leaders than anything else; and 6. both regimes inadequately utilized Nigeria's capabilities in attaining her foreign policy objectives
Informed consent comprehension in African research settings
No full textObjectivePrevious reviews on participants' comprehension of informed consent information have focused on developed countries. Experience has shown that ethical standards developed on Western values may not be appropriate for African settings where research concepts are unfamiliar. We undertook this review to describe how informed consent comprehension is defined and measured in African research settings.MethodsWe conducted a comprehensive search involving five electronic databases: Medline, Embase, Global Health, EthxWeb and Bioethics Literature Database (BELIT). We also examined African Index Medicus and Google Scholar for relevant publications on informed consent comprehension in clinical studies conducted in sub-Saharan Africa. 29 studies satisfied the inclusion criteria; meta-analysis was possible in 21 studies. We further conducted a direct comparison of participants' comprehension on domains of informed consent in all eligible studies.ResultsComprehension of key concepts of informed consent varies considerably from country to country and depends on the nature and complexity of the study. Meta-analysis showed that 47% of a total of 1633 participants across four studies demonstrated comprehension about randomisation (95% CI 13.9–80.9%). Similarly, 48% of 3946 participants in six studies had understanding about placebo (95% CI 19.0–77.5%), while only 30% of 753 participants in five studies understood the concept of therapeutic misconception (95% CI 4.6–66.7%). Measurement tools for informed consent comprehension were developed with little or no validation. Assessment of comprehension was carried out at variable times after disclosure of study information. No uniform definition of informed consent comprehension exists to form the basis for development of an appropriate tool to measure comprehension in African participants.ConclusionsComprehension of key concepts of informed consent is poor among study participants across Africa. There is a vital need to develop a uniform definition for informed consent comprehension in low literacy research settings in Africa. This will be an essential step towards developing appropriate tools that can adequately measure informed consent comprehension. This may consequently suggest adequate measures to improve the informed consent procedure.ObjectifLes normes éthiques élaborées selon les valeurs occidentales ne sont peut-être pas appropriées au contexte africain où les concepts de recherche ne sont pas familiers. Cette revue décrit comment la compréhension du consentement éclairé est définie et mesurée dans les cadres de recherche africains.MéthodesDes recherches ont été effectuées sur Medline, Embase, Global Health, EthxWeb, base de données de la Bioéthique Littérature, Index Medicus African et Google Scholar pour des publications pertinentes sur la compréhension du consentement éclairé dans les études cliniques menées en Afrique sub-saharienne. 29 études répondaient aux critères d'inclusion; une méta-analyse a été possible pour 21 études. La compréhension des participants sur les domaines du consentement éclairé dans toutes les études admissibles a été comparée directement.RésultatsLa compréhension des concepts clés du consentement éclairé varie considérablement selon les pays et dépend de la nature et de la complexité de l’étude. La méta-analyse a montré que 47% des participants ont compris la randomisation (IC95%: 13,9 - 80,9%), 48% ont compris le placebo (IC95%: 19,0 - 77,5%), 30% ont compris le concept de méprise thérapeutique (IC95%: 4,6 - 66,7%). Les outils de mesure de la compréhension du consentement éclairé étaient développés avec peu ou pas de validation.ConclusionsLa compréhension des concepts clés du consentement éclairé est faible en Afrique. Il y a une nécessité vitale d’élaborer une définition uniforme pour la compréhension du consentement éclairé dans les cadres de recherche avec un faible niveau d'alphabétisation en Afrique.ObjetivoLos estándares éticos desarrollados basándose en valores occidentales podrían no ser apropiados para emplazamientos Africanos en donde los conceptos de investigación no son familiares. En esta revisión se describe como la comprensión del consentimiento informado se define y mide en un centro de investigación Africano.MétodosSe buscaron publicaciones relevantes sobre la comprensión del consentimiento informado en estudios clínicos en África subsahariana en Medline, Embase, Global Health, EthxWeb, Bioethics Literature Database, African Index Medicus y Google Scholar. 29 estudios satisfacían los criterios de inclusión y el metaanálisis era posible para 21.

Las herramientas para medir la comprensión del consentimiento informado se desarrollaron con poca o ninguna validación.ConclusionesEn África, la comprensión de conceptos claves del consentimiento informado es pobre. Existe una necesidad vital de desarrollar una definición uniforme para la comprensión del consentimiento informado en lugares con bajos niveles de alfabetización en África
q-Fibonacci sequence spaces and related matrix transformations
No full textIn this paper, we define the sequence spaces ?p(F^ q) (1 ? p< ?) , ??(F^ q) , c(F^ q) and c(F^ q) by using q-Fibonacci band matrix F^ q defined by F^q=F^nk(q)={-Fn+1(q)-1qnFn(q),k=n-1Fn+2(q)-1qnFn(q),k=n0,otherwise(k,n?N).We study some topological properties and give some inclusion relations for these spaces. In addition, we build a bases for the space ?p(F^ q) , compute ?-, ?-, ?- duals of the same space, characterize some matrix classes and examine some geometric properties. © 2022, The Author(s) under exclusive licence to Korean Society for Informatics and Computational Applied Mathematics

No full textSecond-order correlations and purity of unheralded single photons from spontaneous parametric down-conversion
No full textVarious quantum technology applications require high-purity single photons
with high generation rate. Although different methods are employed to generate
such photons, heralded single photons from spontaneous parametric
down-conversion (SPDC) is the most commonly used approach. Photon generation
rate from the heralded single-photon sources are limited by the efficiency of
the detectors to record coincidence detection of the photon pairs which are
lower than the single-photon counts recorded separately on each detector. In
this paper we present a revised expression to calculate second-order temporal
correlation function, for any fixed time window (bin) and report the
experimental characterization of purity of unheralded and heralded single
photons from the SPDC process. With an appropriate choice of time bin for a
given pump power, without heralding we show that higher rate of single photons
with can be generated with very high probability.Comment: 7 pages, 6 figure
Quantum illumination using polarization-entangled photon pairs for enhanced object detection
No full textEntangled light sources for illuminating objects offer advantages over conventional illumination methods by enhancing the detection sensitivity of reflecting objects. The core of the quantum advantage lies in effectively exploiting quantum correlations to isolate noise and detect objects with low reflectivity. This work experimentally demonstrates the benefits of using polarization-entangled photon pairs for quantum illumination and shows that the quantum correlation measure, using CHSH value and normalized CHSH value, is robust against losses, noise, and depolarization. We report the detection of objects with reflectivity () as low as 0.05 and an object submerged in noise with a signal-to-noise ratio of 0.003 using quantum correlation and residual quantum correlation measures, surpassing previous results. Additionally, we demonstrate that the normalized CHSH value aids in estimating the reflectivity of the detected object. Furthermore, we analyze the robustness of the correlation measure under photon attenuation in atmospheric conditions to show the practical feasibility of real-time applications.10 Pages, 8 Figure
