The ijtihâd issues are among important problems of uṣûl al-fiqh (Islamic legal theory). Given al-beyân el-ijtihâd in the meaning of interpreting naṣṣ (text) and al-qiyâs el-jtihâd in the meaning of reaching a verdict of a new issue which is not determined by naṣṣ, it is possible to say that mujtahid (a jurist) is actively in the ijtihâd activity. Thus, the ijtihâd issues has been discussed in uṣûl al-fiqh since early period. The fact that Shâfi‘î refers to ijtihâd issues in his (...) works which have arrived the present day shows that there is a rich accumulation of knowledge about ijtihâd discussions in early period. After Shâfi‘î, the issues were discussed by scholars of Islamic legal theory. Among the Shâfi‘î (uṣûl al-fiqh) works which have arrived the present day, the first work that deals with ijtihâd issues in an ordered, systematic and detailed way is the work of al-Mâwerdî’s el-Ḥâvi’l-Kebîr. In this study, al-Mâwerdî discusses many issues in uṣûl al-fiqh, especially the definition of ijtihâd, its types, the relation between ijtihad and qıyâs, the qualities of mujtahid, iṣâbet (right) and ḫaṭâ’ (fault) in ijtihâd and the provision of ijtihâd. The debates on the ijtihâd issues in Shâfi‘î uṣûl al-fiqh before al-Mâverdî are important our subject. al-Mâwerdî’s view of uṣûl has a close relationship with the accumulation of uṣûl developed prior to him. al-Mâwerdî mentions the views of many scholars who have contributed the accumulation of the sect in the ijtihad issues, especially Shâfi‘î. He refers to the views of scholars from sects other than Shâfi‘î in the issues he discussed. From this point of view, it is certain that to determine the ijtihâd issues in al-Mâwerdî’s el-Ḥâvi’l-Kebîr will also help us to determine the framework and course of debates on ijtihâd in the classical period.

In this article, I argue that the nature of testimony necessitates that we distinguish between testimonies that are based on the informant's sense perception, inference, or on a longer testimonial chain. I further argue that this distinction has epistemic significance, in that it helps us better understand how reliable certain classes of testimonies are and how reliable certain individuals are, based upon the epistemic source that their testimony is ultimately grounded in. I begin the article, in Section 1, by drawing (...) attention to the existence of several different terms for testimony found within the Islamic philosophical tradition. In Section 2, I argue that the essential difference between these terms has to do with the epistemic source that grounds the speaker’s testimony. In Section 3, I move on to explicate how this distinction helps us better understand the reliability of testimony and how it impacts our evaluation of the reliability of different speakers in different contexts. In Section 4, I use this distinction to challenge the necessary condition of speaker competency. Finally, in Section 5, I use the distinction to undermine the belief-transmission view in the epistemology of testimony. (shrink)

Nearly all fractions within the political, economic, and social spheres gave responses to the recent financial crisis. In broad terms, both left-leaning and right-leaning scholars and commentators presented their explanations for the crisis, with confident agendas defining ‘what is wrong’ and how to deal with it. However, as intellectual history shows us, most of those explanations were no less fascinating precisely because they shared more that they acknowledged. A major divide has been over the role of governments in coordinating markets, (...) or, in the case of Roberts’sThe Logic of Discipline, the role of markets in coordinating governments. In this essay, I offer an overview of Alasdair Roberts’s arguments inThe Logic of Discipline. Gradually, I extend the examined issues beyond the state-market dichotomy, arguing that only in understanding the interactive force of the two can a systemic analysis of capitalism hope to be plausible.

The purpose of this paper is two-fold. First, this study measures the contribution of banks and non-bank financial institutions toward the systemic risk of China. Second, the present study investigates the relationship between CEO power, CEO overconfidence, and systemic risk. This study uses the Delta Conditional Value-at-Risk method to measure the systemic risk contribution of firms listed on the Shenzhen and Shanghai stock exchanges over a period of 2006–2018. The results show that non-bank financial institutions are systemically more important compared (...) to banks. We employed fixed-effect regression analysis to show that banks with overconfident CEOs increase the firm’s systemic risk. The results also confirm that powerful CEOs enhance the contribution of non-bank financial institutions to systemic risk, whereas CEO power’s impact was significant only for non-state-owned banks. The findings were further validated by the robustness test results obtained using the two-stage least squares approach. These findings are important for constructing regulations to reduce the contribution of firms to systemic risk. (shrink)

The Cambridge Companion to American Islam offers a scholarly overview of the state of research on American Muslims and American Islam. The book presents the reader with a comprehensive discussion of the debates, challenges and opportunities that American Muslims have faced through centuries of American history. This volume also covers the creative ways in which American Muslims have responded to the myriad serious challenges that they have faced and continue to face in constructing a religious praxis and complex identities that (...) are grounded in both a universal tradition and the particularities of their local contexts. The book introduces the reader to some of the many facets of the lives of American Muslims that can only be understood in their interactions with Islam's entanglement in the American experiment.

Collection of studies on a leading moral philosopher and his work, or dedicated to him.

An enquiry into plant consciousness requires, on the one hand, taking into account recent experiments in plant biology and, on the other hand, refining the theoretical framework of behaviour and the various degrees of cognition. The main goal of this contribution is to advance such a framework by comparing classical animal and human cognition approaches with the theories of minimal cognition. This leads us to interpret more carefully the various plant activities and to highlight the limits of classical theories of (...) zoocentric cognition. In particular, the article shows that the notions of cognition and consciousness are often abusively confused, and with that of behaviour. Once this ambiguity is removed, it is possible to better distinguish several meanings of consciousness and to evaluate their relevance to plant activities. (shrink)

From 1911 to 1913, in big streets and small lanes, in famous parks and thriving stores, and in tea houses and grand restaurants located in such cities as Shanghai, Nanjing, Beijing and Wuchang, numerous business opportunities were born out of the Revolution of 1911. By using the political giants and military leaders around Shanghai, business firms skillfully dealt with the difficulties of the continually changing political situation and managed to keep their businesses afloat, succeeding in their response to the consumption (...) demands of the public. It can be argued that the Revolution of 1911 played a distinct role in the development of businesses in Shanghai during that time. (shrink)

The coronavirus disease 2019 pandemic has affected most countries of the world. The detection of Covid-19 positive cases is an important step to fight the pandemic and save human lives. The polymerase chain reaction test is the most used method to detect Covid-19 positive cases. Various molecular methods and serological methods have also been explored to detect Covid-19 positive cases. Machine learning algorithms have been applied to various kinds of datasets to predict Covid-19 positive cases. The machine learning algorithms were (...) applied on a Covid-19 dataset based on commonly taken laboratory tests to predict Covid-19 positive cases. These types of datasets are easy to collect. The paper investigates the application of decision tree ensembles which are accurate and robust to the selection of parameters. As there is an imbalance between the number of positive cases and the number of negative cases, decision tree ensembles developed for imbalanced datasets are applied. F-measure, precision, recall, area under the precision-recall curve, and area under the receiver operating characteristic curve are used to compare different decision tree ensembles. Different performance measures suggest that decision tree ensembles developed for imbalanced datasets perform better. Results also suggest that including age as a variable can improve the performance of various ensembles of decision trees. (shrink)

The ordering tendency in binary f -Ti solid solution containing 3sp or 4sp simple-metal or 3d transition-metal solute is investigated systematically by the linear muffin-tin orbital method within the atomic sphere approximation . We demonstrated that the effective pairwise interaction energy in a solid solution is equal to half the solute-solute interaction energies and can be evaluated by a supercell total energy approach. The calculations of EPI energy both with and without volume relaxation of the supercells and local density of (...) states show that the EPI energies of Ti-SM and Ti-TM solutions are dominated by different factors. For Ti-SM solutions, the EPI energies are of large absolute values with a negative sign, indicating strong ordering tendency in these solutions. The volume relaxation does not alter the EPI energy substantially. The calculated LDOS shows that the ordering tendency in Ti-SM solutions may be related to the hybridization between the electrons of the SM atoms when they are close to each other. For most Ti-TM solutions, if calculated without relaxation, the absolute EPI energies are very small; however, if calculated with relaxation, they are of relatively large positive values, indicating a clustering tendency in these solutions. By combining the calculated EPI energy and Flinn's model for short-range order strengthening, the increase in critical shear stress ‰ sro due to SRO is estimated for Ti-SM alloys, and the results qualitatively agree with experiment.

We study type 1 premice equipped with supercomplete extenders. In this paper, we show that such premice are normally iterable and all normal iteration trees of type 1 premice has a unique cofinal branch. We give a construction of an KC type model using supercomplete type 1 extenders.

Marxist Historiographies is the first book to examine the ebb and flow of Marxist historiography from a global and cross-cultural perspective. Since the eighteenth century, few schools of historical thought have exerted a more lasting impact than Marxism, and this impact extends far beyond the Western world within which it is most commonly analysed. Edited by two highly respected authors in the field and taking a truly global perspective on this topic, Marxist Historiographies demonstrates clearly the breadth and depth of (...) Marxism's influence in historical writing throughout the world and is essential reading for all students of historiography. (shrink)
