Imam Al-Shafi’i: The Founder of Islamic Law
Authors: Shaista Jabeen  
Published: October 2024

Abu Abdullah Muhammad Ibn Idrees Al-shafi'i is a theologian and renowned Islamic Scholar, who was the first contributor of the principles of Islamic Jurisprudence. He was a famous theologian and it was not his only forte, he also lectured on Poetry, Linguistics and Genealogy as well. His students cane from a varied array of disciplines. Among the four schools of thought of Muslims, Shafi'i is the Imam and founder of his school of thought. He was one of the four great Imams whose legacy on juridical matters and teachings eventually led to the formation of Shafi School of law. He is also the author of several prominent works in the field. Imam Shafi’I wrote many books and according to some narrations, the number is around 123. One of his famous books is Al-Risala. This is a book of his verdict’s specific issues, rather it was a book settling the principles of Islamic jurisprudence upon which every school of thoughts agree. He was one of the first people in the history of Islam who developed this branch of the religion. Another book comprising his rulings called Al-Umm has also become widely popular. Just as his book Al-Risala has the status of the first book and the primary source in the principles of Jurisprudence, like that his book Al-Umm has the status of the primary source in the field of Jurisprudence. The Shafi’i school of Jurisprudence is based on these books. The complete Jurisprudence has been compiled on the basis of these books. Imam Shafi’i write these books in his last year’s, in the early 3rd Century, when he was living in Egypt. In Egypt he not only rearranged Al-Risala, but also revised most of the issues of his Jurisprudence and compiled a collection of them in the form of Kitab Al-Umm. This book was dictated by him to his students and it is through them that it is available today. The four volume book Al-Umm also discussed a special chapter of Jurisprudence, International Islamic Law of War. That’s why it is also used in the formulation of international law. In the Risala which laid down the basis for various legal doctrines, al-Shafi’i established the overriding authority, based only to the Quran and the Sunnah or examples of the Holy Prophet PBUH as transmitted in the traditions. Shafi'i elaborated a system of positive law and a rudimentary legal theory that attracted a number of scholars. His two chief treatises that survived are al-Umm, a collection mainly concerned with positive law and disagreements among the early jurists, and al-Risala, a work on legal theory with particular emphasis on Prophetic Traditions, as a binding source of law. He set a new road towards Islamic Law through these two precious books. His contribution towards Islamic law is able to be discussed and remembered. The article will deal with the contributions of Al- shafi’i in Islamic Law in the light and approach of Al-Umm and Al-Risala.
Single rib fracture. What to expect regarding the duration of pain-related disability? A retrospective observational study and review of literature
Authors: Nageeb Mahmoud Ahmed , Blakely Summre , Wertz Jeffrey , Marie Baro Susan , Horwitz Daniel S. 
Published: October 2024

Background: Pain associated with rib fractures can last particularly long. While it is commonly advised in the outpatient setting to anticipate rib fracture pain to improve relatively within a few weeks, there is no evidence to support this statement. The aim of this study was to examine the duration of pain-related disability following single rib fractures based on the objective clinical records.

Methods: This study retrospectively reviews the clinical inpatient and outpatient records of 37 patients with single rib fractures treated conservatively at our multi-hospital healthcare system from January to December 2022. The duration of pain-related disability was deduced based on several criteria documented in the patients' clinical records. Univariate and multivariate analyses of risk factors (patient age, sex, injury severity score, smoking status, fractured rib, and side) were performed to find a potential correlation with the time to pain improvement.

Results: In this study, the clinical data of 22 males and 15 females with a single rib fracture and a mean age of 54.4 years (range 18.3–81.5 years) were assessed. According to the available clinical records, the mean duration of pain-related disability was 3.12 weeks (range 4–54 days). Analysis of risk factors showed a significant correlation between duration of pain and increased injury severity scores.

Conclusion: While prolonged chest pain is common with rib fractures, a patient with a single rib fracture may be advised that their chest pain and associated disability would significantly improve within an average of 3–4 weeks. The severity of associated injuries was associated with a longer time to pain improvement.

Published: October 2024

A escola precisa trabalhar além da dimensão intelectual, com uma proposta pedagógica que desenvolva a capacidade de autonomia e interação dos indivíduos nos diferentes espaços sociais e em todos os aspectos de sua existência. A reflexão objetiva olhar criticamente para as escolas e a formação humana integral, a partir de discussões que envolvam as diversas dimensões humanas. A discussão é amparada nos teóricos: Giroux, Freire, Mészáros, Brandão e Arroyo. Analisa, também, a Base Nacional Comum Curricular com o intuito de responder que especificidades apresenta para a formação humana integral? Que referenciais o documento contém para as redes de ensino? Consciente que a constituição do sujeito acontece em diferentes espaços e contextos sociais o estudo apontou possibilidades de uma pedagogia emancipatória, de resistência, participativa e crítico-reflexiva para a ação docente e para a formação humana integral. Para que os movimentos emancipatórios e as políticas públicas sejam efetivadas, são fundamentais o conhecimento, a ciência, a racionalidade e a afetividade, bem como ações efetivas de participação pública na distribuição/redistribuição de renda e políticas de inclusão social.

Authors: Soares Denia Patricia , Nossa Silvania Neris , Brugni Talles Vianna , Fully Roberto Miranda Pimentel 
Published: October 2024

O objetivo deste estudo foi identificar se a dualidade do CEO está associada com níveis menores de compliance, e se a presença de auditoria BIG4 modera essa relação nas empresas listadas na Bolsa de Valores (B3). Este estudo é pautado na Instrução CVM 586, divulgada em 2017 com efeitos a partir de 2018, que instituiu novidades sobre disclosure de compliance no Brasil. Desse modo, as hipóteses levantadas partem do pressuposto de que a dualidade do CEO pode impactar negativamente nos níveis de compliance das firmas brasileiras. Nesse sentido, foi possível identificar a influência dessa nova regulamentação no processo de compliance no país e suas associações com a relação entre gestores e presidentes de conselho de administração brasileiros. Extraiu-se dados do Formulário de Referência de 205 empresas, referentes ao CEO, ao Conselho de administração, Auditoria Big4 e compliance. Os testes utilizados foram: teste de média, regressão probit e análise de efeito marginal, com dados em cross-section. Evidências sugerem que as empresas que possuem CEOs que não são presidentes do conselho possuem, na média, maior nível de compliance. Achados adicionais apontam que empresas auditadas por big4 apresentam redução atenuada de compliance quando o CEO é presidente do conselho.

Revealing the Atomic Defects of WS2 Governing Its Distinct Optical Emissions

Published: November 2017

AbstractDefects and their spatial distribution are crucial factors in controlling the electronic and optical properties of semiconductors. By using scanning transmission electron microscopy and electron energy loss spectroscopy, the type of impurities/defects in WS2 subdomains with different optical properties is successfully assigned. A higher population of Cr impurities is found in the W‐terminated edge domain, while the S‐terminated domain contains more Fe impurities, in accordance with the luminescence characteristics of chemical‐vapor‐grown WS2 of a hexagonal shape. In agreement with the first‐principles calculations, the domains with Cr substitutional dopants exhibit strong trion emission. Fe atoms tend to gather into trimer configuration and introduce deep acceptor levels which compensate the n‐type doping and suppress trion emission. It is also discovered that the domain with higher luminescence but smaller defect concentration tends to get oxidized more rapidly and degrade the 2D structure with many triangular holes. Excitons tend to accumulate at the edges of the oxidized triangular holes and results in enhanced PL emission. The findings indicate that choosing stable elements as dopant and controlling the number of specific edge structures within a crystal domain of 2D transitional metal dichalcogenides can be a new route to improve the optical properties of these materials.
Synthesis of Highly Luminescent SnO2 Nanocrystals: Analysis of their Defect‐Related Photoluminescence Using Polyoxometalates as Quenchers

Published: November 2017

AbstractColloidal semiconductor nanocrystals (NCs), called quantum dots (QDs), have been intensively studied because of their excellent photoluminescence (PL) quantum yields. However, commercial QDs such as CdSe and InP contain toxic or expensive rare elements, limiting their sustainable use. This study focuses on nontoxic, stable, and cheap tin oxides, and synthesized luminescent SnO2 NCs of ≈2 nm in size by a heating‐up method. Tin precursors and diols in a high‐boiling point solvent with oleylamine as the surfactant are heated at 240 °C. SnO2 NCs show defect‐related photoluminescence at 400–460 nm by excitation at 370 nm, achieving a high quantum yield of more than 60%. The PL intensity is stable even when the NCs are stored in atmospheric air at room temperature for over 1 year. The defect‐related emissions of the SnO2 NCs are studied using polyoxometalates (POMs) as the PL quencher. POMs efficiently quench the PL emissions by extracting excited electrons from the conduction band and shallow surface defects. The results reveal that PL emissions from SnO2 NCs are associated with radiative charge recombination via shallow defect levels on the surface and in the bulk, demonstrating the effectiveness of the PL quenching technique using POMs in studying the PL emission mechanism in QDs.
