Asās al-maqālāt fī qamʿ al-jahālāt: A Hitherto Unknown Zaydī Heresiography from Northern Iran
Authors: Ansari Hassan , Foroughi Rouhallah , Schmidtke Sabine 
Published: August 2021

Abstract
This paper revolves around a hitherto unknown heresiography from northern Iran, Asās al-maqālāt fī qamʿ al-jahālāt, which is preserved in a unique manuscript contained in a majmūʿa (Ms. Tehran, Majlis 10727). In the introduction, we describe the multitext codex, one of the few extant codices testifying to the continuous presence of Zaydism in northern Iran beyond the sixth/twelfth century. Additionally, we discuss two alternative tentative identifications of the author of Asās al-maqālāt, Abū Muḍar Shurayḥ b. al-Muʾayyad al-Muʾayyadī al-Shurayḥī and Muḥammad b. al-Ḥasan al-Shurayḥī al-Muʾayyadī. While the latter is entirely unknown, Abū Muḍar is renowned for his Asrār al-Ziyādāt, and we attempt to situate him more precisely in the chronology of Zaydī scholarship. Finally, we provide an editio princeps of Asās al-maqālāt fī qamʿ al-jahālāt.
Eugenio Griffini and Zaydi Studies in the Light of His Correspondence with Ignaz Goldziher, 1908 through 1920
Authors: Sagaria Rossi Valentina 
Published: August 2021

Abstract
Eugenio Griffini (1878-1925), the Italian Arabist, was the person who first realized the relevance and cultural significance of the Zaydi manuscript sources, who conveyed the largest Western collection of Zaydi manuscripts (the Caprotti collection) to the Ambrosiana Library in Milan in 1908, and who first immersed himself in this unique and virgin collection of manuscripts of Yemeni origin. Through his exploration of a treasure of nearly 2,000 manuscripts, he became experienced and acknowledged in the practice of reporting extended notes excerpted from the manuscript texts he examined. This outstanding experience over the course of twenty years of study and first-hand research at the Ambrosiana allowed him to unveil the existence and identify hundreds of unknown texts, opening up unexplored fields of interest and investigations into Zaydi literary production. With an extremely collaborative spirit, he lavished on many Orientalist scholars the insights that he had gleaned from the manuscripts he had come across, providing them with partial transcriptions and readings, sometimes upon request and other times even going beyond the requests. This article focusses on Griffini’s life and scholarly activity, particularly his involvement with Zaydi works, in the light of his correspondence with Ignaz Goldziher (1850-1921), of which an annotated edition is provided. The correspondence spans the period from 1908 to 1920 and reveals Griffini’s attitude towards his main projects: the cataloguing of the first three series of the Caprotti collection and his magnum opus, the edition of the Majmūʿ al-fiqh attributed to Zayd b. ʿAlī, on the basis of the Ambrosiana’s exemplars.
Do Accidents Need a Substrate? Critical Edition of al-Ḥasan al-Raṣṣāṣ’s Masʾala fī kayfiyyat wujūd al-aʿrāḍ
Authors: Ahmadi Mostafa , Ansari Hassan , Thiele Jan 
Published: August 2021

Abstract
This article offers an editio princeps of al-Ḥasan al-Raṣṣāṣ’s Masʾala fī kayfiyyat wujūd al-aʿrāḍ. In this text, al-Raṣṣāṣ argues in accordance with the Bahshamī theory that not all accidents need a substrate (maḥall). Although most accidents depend on atoms as their locus of inherence, there are three exceptions: the accident of “annihilation” (fanāʾ), whose existence in a substrate is inconceivable, and “will” (irāda) and “aversion” (karāha), which either subsist in a human body or exist without a substrate in the case of God.
Sixth/Twelfth-Century Zaydī Theologians of Yemen Debating Avicennan Philosophy
Authors: Ansari Hassan , Schmidtke Sabine 
Published: August 2021

Abstract
This article offers critical editions of three texts by Zaydī theologians of sixth/twelfth-century Yemen refuting philosophical notions. The three texts are Qāḍī Jaʿfar b. Aḥmad b. ʿAbd al-Salām al-Buhlūlī’s (d. 573/1177-78) Kitāb al-Risāla al-munāṣifa li-l-mutakallimīn wa-l-falāsifa (Masʾalat al-nafs) and two tracts by al-Ḥasan al-Raṣṣāṣ (d. 584/1188), al-Masʾala al-kāshifa ʿan buṭlān shubhat al-falāsifa, a refutation of the philosophers’ doctrine of the eternity of the world, and Masʾala fī ibṭāl al-qawl bi-talāzum al-hayūlā wa-l-ṣūra wa-anna l-jism murakkab minhumā, a refutation of hylomorphism. Qāḍī Jaʿfar’s tract, of which only a fragment has come down to us, contains four extensive quotations from an unidentified philosophical work. These are strikingly similar to those cited by Rukn al-Dīn Ibn al-Malāḥimī (d. 536/1141) in his Tuḥfat al-mutakallimīn fī l-radd ʿalā l-falāsifa; likewise, Qāḍī Jaʿfar’s responses to the arguments of the philosophers closely resemble those given by Ibn al-Malāḥimī. However, a comparison of the relevant passages shows that the possibility that Qāḍī Jaʿfar had consulted Ibn al-Malāḥimī’s Tuḥfa as his source can safely be excluded. Both rather seemed to have relied on a common and so far unidentified source, possibly written by a Muʿtazilī author. Qāḍī Jaʿfar’s tract is thus another early Muʿtazilī critique of Avicennan philosophy that can shed some additional light on the reception of Ibn Sīnā’s (d. 428/1037) philosophy among the mutakallimūn before Ibn al-Malāḥimī.
Organizational Responses to the covid-19 Crisis by Universities in Poland: A Survey of Student Attitudes
Authors: Godonoga Ana , Gruszka Danuta 
Published: August 2021

Abstract
The global health crisis caused by the sars-CoV-2 virus has impacted higher education systems worldwide. Emergency remote teaching strategies have been common organizational responses, which came with challenges, particularly in systems that lacked the capacity for digital provision. Building on strategic and crisis management theory and literature, this study investigates student attitudes towards organizational responses to the crisis in public higher education institutions in Poland. Drawing on findings of an online survey completed by 359 students from 61 institutions, this research has revealed that more than half of the respondents were satisfied with organizational responses to the crisis. Instructors’ self-motivation was identified as a key enabler of a successful implementation of distance learning, while their lack of familiarity with e-learning and technology were found as dominant barriers. The findings of this research can support institutions in other contexts to strengthen their commitment to educational improvement in a period of crisis and digital transformation.
Reforming Schools: A Comparison of Chinese Urban vs. Rural School Principals’ Values, Views & Visions

Published: August 2021

Abstract
Principal as the key to school reform has been a frequently discussed topic in the research literature. However, few studies have investigated principals’ own values, views and visions and how these may affect reform in their schools. The study reported in this paper intends to fill this void. It is a joint effort by American and Chinese education scholars to explore and examine the profiles, preparation and perspectives of urban and rural principals in China, based on the conceptual framework and research methodology of the American national Study of the Education of Educators and the earlier comparative study of Chinese, American and Australian school principals. A comprehensive principal survey was administered to several hundred urban and rural school principals in China and interviews were conducted with selected principals. Our study findings reveal both similarities and differences in values, views and visions between urban and rural school principals, and a huge gap in the quality and equality of education between urban and rural schools. Although Chinese principals are in general progressive and liberal in their fundamental beliefs and values, they perceive great difficulties in realizing their visions for ideal schools and recognize major obstacles to reform because of the existing school conditions, the national examination system, and certain policy restrictions on their autonomy and decision-making power in schools. Findings from this study provide special insight to policy makers and education reformers and urge them to create necessary policies, improve conditions, and increase autonomy and decision-making power for principals to manage and effect changes in their schools, especially those in rural and minority areas.
Improving Quality Physical Education: Conceptual and Practical Framework, and Barriers to Its Global Implementation

Published: August 2021

Abstract
To exert benefits of physical education and enhance the health of teenagers, the idea of Quality Physical Education (qpe) had been put into practice since 1995 as the guideline for the implementation of physical education in K-12 schools in the United States. qpe consists of two parts: the conceptual framework and practical guidelines, which contain four core elements: “Opportunity to Learn,” “Meaningful Content,” “Appropriate Instruction,” and “Student and Program Assessment.” Each core component is broken down into sections, subsections, and programmatic elements, to fit into unesco’s benchmarks, which regulate the overall process and procedures in physical education as minimum standards, offering strong support for educators to design and implement high qpe. In the global endeavor to implement qpe, however there are major barriers, specifically institutional barriers, teacher-related barriers, and student-related barriers which prevent qpe to be fully and effectively adopted.

Published: August 2021

Objective: Patients with recurrent respiratory papillomatosis (RRP) have significant vocal dysfunction which affects their performance at work. This study aimed to evaluate voice-related work productivity before and after ablative treatment for RRP. Methods: This is a prospective case series conducted at 2 academic laryngology outpatient clinics. Adult employed patients with RRP completed the Work Productivity & Activity Impairment instrument (WPAI), Voice Handicap Index (VHI-10), WorkHoarse, Hospital Anxiety and Depression Scale (HADS), and a demographics questionnaire immediately before and 1 month after ablative treatment of papilloma. The primary outcome measure was the change in work productivity impairment domain of the WPAI, and changes in ratings before and after ablation were compared using a Wilcoxon Signed-Rank test. Results: The 32 participants (mean age 45, 84% male) had a median (interquartile range) voice-related work productivity impairment score of 48.8% (30.0) at baseline which was improved to 5.0% (10.0) at 1 month after surgical ablation of papillomata (difference 30.0% (30.0) improvement). For the secondary outcome measures, there were significant improvements in VHI-10 ( P < .001), self-reported voice quality ( P = .002), and Workhoarse ( P = .001), but no significant change in HADS. Conclusion: Patients with RRP experience significant voice-related work productivity impairment, and ablation of papillomata significantly improves work productivity.

Objective: The effects of mood disorders on mortality may be mediated by their effects on the risk of dementia, and interventions to reduce the occurrence of dementia may reduce their overall mortality. This study aimed to investigate the direct effects of depressive and bipolar disorders on the 6-year risk of mortality and also their indirect effects on mortality due to their effect on the risk of dementia. Methods: A total of 5101 Koreans were selected from a community-based prospective cohort study, and 6-year risks of mortality and dementia in participants with depressive and bipolar disorders were estimated by Cox proportional hazard analysis. The direct and indirect effects of depressive and bipolar disorders on the risk of mortality were estimated using structural equation modeling. Results: The depressive and bipolar disorder groups showed 51% and 85% higher 6-year mortality, and 82% and 127% higher risk of dementia, respectively, compared to euthymic controls. The effects of depressive and bipolar disorders on mortality were mainly mediated by their effects on the risk of dementia in a structural equation model. The direct effects of each mood disorder on mortality were not significant. Conclusion: Both depressive and bipolar disorders increased the risks of mortality and dementia, and the effects of mood disorders on mortality were mainly mediated through dementia. As dementia occurs later in life than mood disorders, measures to prevent it may effectively reduce mortality in individuals with a history of mood disorders, as well as being more feasible than attempting to control other causes of death.
Personalization of Medical Treatment Decisions: Simplifying Complex Models while Maintaining Patient Health Outcomes
Authors: Weyant Christopher , Brandeau Margaret L. 
Published: August 2021

Background Personalizing medical treatments based on patient-specific risks and preferences can improve patient health. However, models to support personalized treatment decisions are often complex and difficult to interpret, limiting their clinical application. Methods We present a new method, using machine learning to create meta-models, for simplifying complex models for personalizing medical treatment decisions. We consider simple interpretable models, interpretable ensemble models, and noninterpretable ensemble models. We use variable selection with a penalty for patient-specific risks and/or preferences that are difficult, risky, or costly to obtain. We interpret the meta-models to the extent permitted by their model architectures. We illustrate our method by applying it to simplify a previously developed model for personalized selection of antipsychotic drugs for patients with schizophrenia. Results The best simplified interpretable, interpretable ensemble, and noninterpretable ensemble models contained at most half the number of patient-specific risks and preferences compared with the original model. The simplified models achieved 60.5% (95% credible interval [crI]: 55.2–65.4), 60.8% (95% crI: 55.5–65.7), and 83.8% (95% crI: 80.8–86.6), respectively, of the net health benefit of the original model (quality-adjusted life-years gained). Important variables in all models were similar and made intuitive sense. Computation time for the meta-models was orders of magnitude less than for the original model. Limitations The simplified models share the limitations of the original model (e.g., potential biases). Conclusions Our meta-modeling method is disease- and model- agnostic and can be used to simplify complex models for personalization, allowing for variable selection in addition to improved model interpretability and computational performance. Simplified models may be more likely to be adopted in clinical settings and can help improve equity in patient outcomes.

Published: August 2021

Introduction: Induction chemotherapy (IC) followed by concurrent chemoradiotherapy (CCRT) is recommended for larynx-preserving treatment of locally advanced hypopharyngeal cancer (LAHC). However, the conventional evaluation of response is not robust enough to predict the outcome of subsequent treatments. This study aimed to develop an imaging biomarker using changes in radiomic features in invasive tumor front (ITF) by IC to predict treatment outcome of subsequent CCRT in LAHC. Methods: From 2006 to 2018, 59 computed tomography (CT) scan images before and after IC in patients with LAHC were used to contour the gross tumor volumes (GTVs). A total of 48 delta-volume radiomics features were acquired from the absolute spatial difference of GTVs (delta-GTV) before and after IC, conceptually representing a consistent portion of ITF. Least absolute shrinkage and selection operator regression (LASSO) was used to select features for establishing the model generating radiomic score (R score). Results: A model including 5 radiomic features from delta-GTV to predict better progression-free survival (PFS) of patients receiving subsequent CCRT was established. The R score was validated with all datasets (area under the curve 0.77). Low R score (<–0.16) was associated with improved PFS ( p < 0.05). Conclusions: The established radiomic model for ITF from radiomic features of delta-GTV after IC might be a potential imaging biomarker for predicting clinical outcome of subsequent CCRT in LAHC.
Early Failure of a Polyvinyl Alcohol Hydrogel Implant With Osteolysis and Foreign Body Reactions in an Ovine Model of Cartilage Repair
Authors: Cercone Marta , Chevalier Jacqueline , Kennedy John G. , Miller Andrew D. , Fortier Lisa A. 
Published: August 2021

Background: Hemiarthroplasty using a polyvinyl alcohol (PVA) hydrogel synthetic implant has been suggested as a good alternative to arthrodesis for the treatment of hallux rigidus. However, failure rates as high as 20% have been recorded. Purpose: To characterize the pathological processes in bone, cartilage, and the synovial membrane after PVA hemiarthroplasty in an ovine model with 6 months of follow-up. Study Design: Controlled laboratory study. Methods: A unilateral osteochondral defect (8-mm diameter × 10-mm depth) was made in the medial femoral condyle in 6 sheep. Animals were randomized to receive a PVA implant (n = 4) or to have an empty defect (n = 2) and were monitored for 6 months. Patellofemoral radiographs were obtained at monthly intervals, and quantitative computed tomography was performed at the end of the study. After death, the joints were macroscopically evaluated and scored. Osteochondral and synovial membrane histological findings were assessed using modified Osteoarthritis Research Society International (OARSI) and aseptic lymphocyte-dominated vasculitis-associated lesion (ALVAL) scoring systems. Immunohistochemistry using Iba1 was performed to evaluate activated macrophage infiltration. Results: Overall, 2 sheep with PVA implants were euthanized at 1 and 5 months because of uncontrollable pain and lameness (failed implants). Quantitative computed tomography showed that sheep with failed implants had 2.1-fold more osteolysis than those with successful implants. The sheep with failed implants had osteoarthritis with extensive glycosaminoglycan loss and cartilage fibrillation of the condyle and opposing tibial surface on histological examination. A foreign body reaction with severe chronic lymphoplasmacytic and granulomatous inflammation with giant cells was detected surrounding the implant. The synovial membrane ALVAL score was 9 of 19 and 14 of 19 in failed implants with synovial hyperplasia and lymphoplasmacytic and macrophage infiltration. In contrast, the synovial membrane in successful implants and empty defects was normal (ALVAL score = 0/19). Immunolabeling for Iba1 in failed implants confirmed extensive and dense macrophage infiltration within the condyle and synovial membrane, with the highest immunoreactive score (9/9). Conclusion: PVA hydrogel implants had a 50% failure rate with uncontrollable pain, severe osteolysis, inflammation, and foreign body reactions. Clinical Relevance: The failure rate and pathological characteristics of the PVA implants suggest that their use should not be continued in human patients without further in vivo safety studies.
Rethinking the measurement of occupational task content
Authors: Haslberger Matthias 
Published: August 2021

AbstractWhich tasks workers perform in their jobs is critical for how technological change plays out in the labour market. This article critically reviews existing measures of occupational task content and makes the case for rethinking how this concept is operationalised. It identifies serious shortcomings relating to the theoretical content and the empirical implementation of existing measures. Based on survey data from European Union countries between 2000 and 2015, it then introduces novel measures of routine task intensity and task complexity at the International Standard Classification of Occupations 1988 two-digit level that address these shortcomings. The indices will contribute to a more theoretically informed understanding of technological change and benefit both labour economists and sociologists in investigating the nature of recent technological change.
Psychological well-being in childhood: The role of trait emotional intelligence, regulatory emotional self-efficacy, coping and general intelligence

Published: August 2021

Given the increase of mental health problems in youth, focusing on the promotion of psychological well-being is essential. Among the variables recognized as linked to children’s psychological well-being, trait emotional intelligence, emotional self-efficacy and coping seem to be crucial, whereas the role played by intelligence is still controversial. In the present study, we explored the combined effects of these variables, aimed at disentangling their unique contribution to psychological well-being of 74 children (41 males, mean age: 9.03 years). We administered verbal and reasoning tests as intelligence measures and self-report questionnaires to assess trait emotional intelligence, regulatory emotional self-efficacy, coping styles, psychological well-being. Correlations revealed two independent clusters of variables: a first cluster including intelligence indexes and a second cluster including psychological well-being, trait emotional intelligence, regulatory emotional self-efficacy and adaptive coping styles. Hierarchical regression analyses showed that only trait emotional intelligence and positive restructuring coping style significantly contributed to psychological well-being. This study highlights that, unlike general intelligence, trait emotional intelligence was associated to psychological well-being, whereas coping styles play a negligible role in explaining this relationship. These findings are valuable in identifying the most relevant factors for children’s adjustment and in enhancing emotion-related aspects in interventions for psychological well-being promotion.
