La notion de ‘awra selon Ab l- asan ‘Al b. Mu ammad b. al-Qa an al-Fas (m. 628 /1231) The Concept of ‘awra according to Abu l- asan ‘Ali b. Mu ammad al-Qa an al-Fas (d. 628/1231)  [cached]

Abstract: Ibn al-Qa an al-Fas (m. 628/1231), “intellectuel organique” au sens plein du régime almohade (524-667/1130-1269), a rédigé le texte sans doute le plus exhaustif jamais écrit en islam sur le corps “montré” et “regardé” envisagé sous l’angle de la Loi révélée. Ce traité traduit l’une des composantes fondatrices de l’idéologie almohade : la réaffirmation de toutes les prescriptions légales relatives au corps en tant qu’il éveille les “passions” des hommes, surtout des hommes, et des femmes. La réflexion fouillée d’Ibn al-Qa an s’articule et se développe naturellement autour de la notion coranique de ‘awra. Il appara t que le catalogue d’interdits éthico-légal qu’il met au jour ne repose pas sur une quelconque “sacralité” du corps mais plut t sur la volonté de préserver la pureté de lignages réputés conformes à “la nature créée”. Le puritanisme, affectant principalement les femmes, qui informe de part en part le Kitab al-na ar d’Ibn al-Qa an al-Fas rappelle celui de bien des courants de l’islam contemporain. Ibn al-Qa an al-Fas (d. 628/1231) was a scholar in the service of the Almohad regime (524-667/1130-1269). He is the author of probably the most exhaustive treatise ever written in Islam on the body as it could be “shown” or “looked at” according to the divine Law. This treatise analyses a topic which is constituent to the Alomohad ideology : the reassessment of the legal prescritions related to the body as it arouses passions among human beings, especially men, but also women. The elaborate analysis of Ibn al-Qa an evolves around the Coranic concept of ‘awra. His list of what is ethically and legally forbidden does not rely on the idea of the body as sacred, but rather seeks to protect the purity of lineages, believed to be a reflection of the created “nature.” The puritanism of Ibn al-Qa an which comes out in his Kitab al-Na ar affects mainly women, and reminds us of some contemporary Islamic movements.

Abstract: An ensemble of genetic networks that describe how the model fungal system, Neurospora crassa, utilizes quinic acid (QA) as a sole carbon source has been identified previously. A genetic network for QA metabolism involves the genes, qa-1F and qa-1S, that encode a transcriptional activator and repressor, respectively and structural genes, qa-2, qa-3, qa-4, qa-x, and qa-y. By a series of 4 separate and independent, model-guided, microarray experiments a total of 50 genes are identified as QA-responsive and hypothesized to be under QA-1F control and/or the control of a second QA-responsive transcription factor (NCU03643) both in the fungal binuclear Zn(II)2Cys6 cluster family. QA-1F regulation is not sufficient to explain the quantitative variation in expression profiles of the 50 QA-responsive genes. QA-responsive genes include genes with products in 8 mutually connected metabolic pathways with 7 of them one step removed from the tricarboxylic (TCA) Cycle and with 7 of them one step removed from glycolysis: (1) starch and sucrose metabolism; (2) glycolysis/glucanogenesis; (3) TCA Cycle; (4) butanoate metabolism; (5) pyruvate metabolism; (6) aromatic amino acid and QA metabolism; (7) valine, leucine, and isoleucine degradation; and (8) transport of sugars and amino acids. Gene products both in aromatic amino acid and QA metabolism and transport show an immediate response to shift to QA, while genes with products in the remaining 7 metabolic modules generally show a delayed response to shift to QA. The additional QA-responsive cutinase transcription factor-1β (NCU03643) is found to have a delayed response to shift to QA. The series of microarray experiments are used to expand the previously identified genetic network describing the qa gene cluster to include all 50 QA-responsive genes including the second transcription factor (NCU03643). These studies illustrate new methodologies from systems biology to guide model-driven discoveries about a core metabolic network involving carbon and amino acid metabolism in N. crassa.

Abstract: China's 2007 Open Government Information Regulations is widely considered as a milestone in the country's information policy history and is praised as a "sunshine program".The Environmental Information Disclosure Decree was the first to operationalize these general regulations into a sectoral information disclosure system on environment.This study assessed the implementation of the environmental information disclosure system about six months after the Decree took effect on May 1,2008.Through reviewing the websites of all 31 provincial Environmental Protection Bureaus and the Ministry of Environmental Protection,conducting an experiment with actual information disclosure request,and through interviews with all provincial Environmental Protection Bureaus,this article concluded that the implementation of the environmental information disclosure system still falls short.Future improvements should focus on further publicity of the regulations and decree to enhance public participation,the establishment of an independent evaluation and supervision system for information disclosure,the exchange of experiences and best practices among provincial Environmental Protection Bureaus,and on strengthening the legal status of environmental information disclosure.

Abstract: Question answering (QA) systems provide an intuitive way of requesting concise information from a givendata source. An important stage of such a system is the passage ranking stage, which ranks the possibleanswers based on their relevance to the question. There has been a lot of previous work on passageranking, employing lexical, semantic or syntactic methods, but to our knowledge there has been no methodthat comprehensively combines all 3 features. In this paper, we present a passage ranking technique thatleverages lexical, semantic and syntactic features together to rank the answers efficiently and effectively.This paper highlights the differences and improvements of the proposed technique over existing state-ofthe-art techniques like SSTK and IBM Model. The passage ranking technique has been evaluated withTREC QA dataset and is observed to give a significant 26.5% improvement in MRR over the existing stateof-the-art SSTK technique.

Abstract: In the present study we employed 7-NI, reportedly a selective inhibitor of neuronal nitric oxide synthase (NOS) and the non-specific potent NOS inhibitor I-NAME, to investigate the possible involvement of nitric oxide (NO) in quinolinic acid (QA)-induced striatal toxicity in the rat. QA was administered unilaterally into the striatum of adult Wistar rats in the single dose of 150 nmol/L. The second and third group were treated with 7-NI and QA and I-NAME and QA. The control group was treated with O.9% saline solution likewise. Nitrite levels were decreased in the ipsi- and contralateral striatum, forebrain cortex and hippocampus in the group treated with NOS inhibitors (7-NI, I-NAME) and QA compared to QA-treated animals. As 7-NI selectively inhibits the neuronal form of NOS, this study suggests that NO produced from a neuronal and not an epithelial source may contribute to neuronal damage in this model.

Abstract: Background: Clinical implementation of enhanced dynamic wedges (EDW) requires, as any other dynamic treatment, very serious quality assurance (QA) program. In this work, we presented the results of six-month evaluation of Varian enhanced dynamic wedges and detailed QA program for those wedges. Methods: The Sun Nuclear Daily QA Check 2 was used for QA purpose. The QA program included daily and monthly checks. The daily QA program included central axis dose and wedge angle measurements. Within the monthly QA program wedge factors and delivered STTs from the Dynalog files were checked. Results: Our daily QA measurements of dose and wedge angle showed the reproducibility error less than ±1.5%. On the other hand, monthly QA measurements of wedge factor the reproducibility error was less than ±0.5%. The monthly QA check of delivered STTs showed excellent agreement. Conclusion: During the six-month quality control we observed a good reproducibility in the delivery of EDW treatment. Also, the Sun Nuclear Daily QA Check 2 showed to be very satisfying in QA of the EDW treatment.

Abstract: This paper presents a multilayered architecture that enhances the capabilities of current QA systems and allows different types of complex questions or queries to be processed. The answers to these questions need to be gathered from factual information scattered throughout different documents. Specifically, we designed a specialized layer to process the different types of temporal questions. Complex temporal questions are first decomposed into simple questions, according to the temporal relations expressed in the original question. In the same way, the answers to the resulting simple questions are recomposed, fulfilling the temporal restrictions of the original complex question. A novel aspect of this approach resides in the decomposition which uses a minimal quantity of resources, with the final aim of obtaining a portable platform that is easily extensible to other languages. In this paper we also present a methodology for evaluation of the decomposition of the questions as well as the ability of the implemented temporal layer to perform at a multilingual level. The temporal layer was first performed for English, then evaluated and compared with: a) a general purpose QA system (F-measure 65.47% for QA plus English temporal layer vs. 38.01% for the general QA system), and b) a well-known QA system. Much better results were obtained for temporal questions with the multilayered system. This system was therefore extended to Spanish and very good results were again obtained in the evaluation (F-measure 40.36% for QA plus Spanish temporal layer vs. 22.94% for the general QA system).

Abstract: In this paper, we describe a way to access Arabic Web Question Answering (QA) corpus using a chatbot, without the need for sophisticated natural language processing or logical inference. Any Natural Language (NL) interface to Question Answer (QA) system is constrained to reply with the given answers, so there is no need for NL generation to recreate well-formed answers, or for deep analysis or logical inference to map user input questions onto this logical ontology; simple (but large) set of pattern-template matching rules will suffice. In previous research, this approach works properly with English and other European languages. In this paper, we try to see how the same chatbot will react in terms of Arabic Web QA corpus. Initial results shows that 93% of answers were correct, but because of a lot of characteristics related to Arabic language, changing Arabic questions into other forms may lead to no answers.
