The most common inherited cause of two genetically and clinico-pathologically overlapping neurodegenerative diseases, amyotrophic lateral sclerosis (ALS) and frontotemporal dementia (FTD), is the presence of expanded GGGGCC intronic hexanucleotide repeats in the C9orf72 gene. Aside from haploinsufficiency and toxic RNA foci, another non-exclusive disease mechanism is the non-canonical translation of the repeat RNA into five different dipeptide repeat proteins (DPRs), which form neuronal inclusions in affected patient brains. While evidence from cellular and animal models supports a toxic gain-of-function of pathologic poly-GA, poly-GR, and poly-PR aggregates in promoting deposition of TDP-43 pathology and neurodegeneration in affected brain areas, the relative contribution of DPRs to the disease process in c9FTD/ALS patients remains unclear. Here we have used the proximity-dependent biotin identification (BioID) proximity proteomics approach to investigate the formation and collective composition of DPR aggregates using cellular models. While interactomes of arginine rich poly-GR and poly-PR aggregates overlapped and were enriched for nucleolar and ribosomal proteins, poly-GA aggregates demonstrated a distinct association with proteasomal components, molecular chaperones (HSPA1A/HSP70, HSPA8/HSC70, VCP/p97), co-chaperones (BAG3, DNAJA1A) and other factors that regulate protein folding and degradation (SQSTM1/p62, CALR, CHIP/STUB1). Experiments in cellular models of poly-GA pathology show that molecular chaperones and co-chaperones are sequestered to the periphery of dense cytoplasmic aggregates, causing depletion from their typical cellular localization. Their involvement in the pathologic process is confirmed in autopsy brain tissue, where HSPA8, BAG3, VCP, and its adapter protein UBXN6 show a close association with poly-GA aggregates in the frontal cortex, temporal cortex, and hippocampus of c9FTLD and c9ALS cases. The association of heat shock proteins and co-chaperones with poly-GA led us to investigate their potential role in reducing its aggregation. We identified HSP40 co-chaperones of the DNAJB family as potent modifiers that increased the solubility of poly-GA, highlighting a possible novel therapeutic avenue and a central role of molecular chaperones in the pathogenesis of human C9orf72-linked diseases.
Hopping path planning in uncertain environments for planetary explorations
Authors: Sakamoto Kosuke , Kubota Takashi
Published: February 2022

Hopping robots, called hoppers, are expected to move on rough terrains, such as disaster areas or planetary environments. The uncertainties of the hopping locomotion in such environments are high, making path planning algorithms essential to traverse these uncertain environments. Planetary surface exploration requires to generate a path which minimises the risk of failure and maximises the information around the hopper. This paper newly proposes a hopping path planning algorithm for rough terrains locomotion. The proposed algorithm takes into account the motion uncertainties using Markov decision processes (MDPs), and generates paths corresponding to the terrain conditions, or the mission requirements, or both. The simulation results show the effectiveness of the proposed route planning scheme in three cases as the rough terrain, sandy and hard ground environment, and non-smooth borders.
Body Composition and Bone Health Status of Jockeys: Current Findings, Assessment Methods and Classification Criteria
Authors: Dunne Arthur , Warrington Giles , McGoldrick Adrian , Pugh Jennifer , Harrison Michael , Cullen SarahJane
Published: February 2022

Jockeys are unlike other weight-making athletes as the sport of horse racing requires strict weight management to meet the racing stipulations, protracted working hours and an extended racing season with limited downtime. Several studies have reported on the body composition and bone status of male and female professional and retired jockeys, yet the variety of assessment techniques, lack of standardised testing protocols and classification inconsistency make interpretation and comparison between studies problematic. This review aimed to appraise the existing body composition and bone health evidence in jockeys and evaluate the assessment methods and classification criteria used. Dual-energy X-ray absorptiometry (DXA) has been used most frequently in jockey research to assess body composition and bone status, while various generic skinfold equations have been used to predict body fat percentage. Evidence indicates flat jockeys are now taller and heavier than the data reported in earlier studies. Absolute fat mass has steadily increased in male jockeys in the last decade. The bone status of male jockeys remains a concern as constant low bone density (BMD) is evident in a large percentage of young and experienced professional jockeys. Due to limited studies and variations in assessment methods, further research is required to investigate bone turnover markers in male and female jockeys. A standardised testing protocol using internationally recognised assessment guidelines is critical for the accurate interpretation and evaluation of body composition and bone health measurements. Furthermore, establishing jockey-specific BMD and bone turnover reference ranges should be considered using existing and future data.

Authors: Elghaffar Hossam Abd , Guindi Sherif , Magdy Mahmoud Mohamed , Alakkad Mona , El Shafei Reham Rafei
Published: February 2022

Background

Vertigo in paediatric age is not a rare condition. However, a lack of awareness about causes of dizziness in children besides the absence of standard diagnostic workup often leads to unnecessary procedures in managing these cases. The purpose of this cross-sectional study was to determine the prevalence and frequency distribution of balance abnormalities in dizzy children. Additionally, the questionnaire’s utility as a screening tool and its predictive accuracy are discussed. Thus, an organized strategy can be allocated to assist the diagnostic process, which is likely to eliminate unnecessary and costly evaluations.

Results

This study comprised 848 children who presented with any of the dizzy symptoms referred to the Audio-Vestibular Unit, Fayoum University Hospital. The suggested diagnosis was 23.9% of the cases suffered from otitis media either alone or combined with other diseases, while 17.6% had benign paroxysmal vertigo of childhood. Migraine patients represented 11.2% of the cases. Only 5.5% of subjects had benign paroxysmal positional vertigo. 78.3% of cases with possible diagnosis showed agreement in diagnosis by both paediatric dizziness questionnaire and the final diagnosis reached by a full assessment of the patients.

Conclusion

Diagnosing dizziness in children is challenging; nevertheless, a structured history taken in conjunction with a vestibular examination is crucial for establishing an accurate diagnosis. The questionnaire appears to be an even-handed tool for diagnosing dizzy children.

A Simple Incentive Mechanism to Alleviate the Burden of Organ Wastage in Transplantation
Authors: Tunç Sait , Sandıkçı Burhaneddin , Tanrıöver Bekir
Published: February 2022

Despite efforts to increase the supply of donated organs for transplantation, organ shortages persist. We study the problem of organ wastage in a queueing-theoretic framework. We establish that self-interested individuals set their utilization levels more conservatively in equilibrium than the socially efficient level. To reduce the resulting gap, we offer an incentive mechanism that recompenses candidates returning to the waitlist for retransplantation, who have accepted a predefined set of organs, for giving up their position in the waitlist and show that it increases the equilibrium utilization of organs while also improving social welfare. Furthermore, the degree of improvement increases monotonically with the level of this nonmonetary compensation provided by the mechanism. In practice, this mechanism can be implemented by preserving some fraction of the waiting time previously accumulated by returning candidates. A detailed numerical study for the U.S. renal transplant system suggests that such an incentive helps significantly reduce the kidney discard rate (baseline: 17.4%). Depending on the strength of the population’s response to the mechanism, the discard rate can be as low as 6.2% (strong response), 12.4% (moderate response), or 15.1% (weak response), which translates to 1,630, 724, or 338 more transplants per year, respectively. Although the average quality of transplanted kidneys deteriorates slightly, the resulting graft survival one-year posttransplant remains stable around 94.8% versus 95.0% for the baseline. We find that the optimal Kidney Donor Profile Index score cutoff, defining the set of incentivized kidneys, is around 85%, which coincides with the generally accepted definition of marginal kidneys in the medical community.

The relationship between social support and parent identity in community playgroups
Authors: Townley Cris
Published: February 2022

Community playgroups are member-run parenting groups in Australia, aligned with early childhood services. Parents and carers meet weekly with their babies, toddlers and preschool children. Through interviews with mothers who attend community playgroups, I find that these playgroups are important sites of social support for parents. Social support is interwoven with parental and family identity, and the shift in identity when becoming a parent. This is demonstrated through three themes: making a connection, shared practices and language, and judgement and respect. Parents seek out a playgroup in which to belong, where they feel included and respected. These findings can inform the creation and operation of parenting groups.

Published: February 2022

Introduction

The coronavirus disease 2019 (COVID-19) pandemic continues to spread globally and as of February 4, 2021, there are more than 26 million confirmed cases and more than 440,000 deaths in the United States (US). A top priority of the Centers for Disease Control and Prevention (CDC) is to identify risk factors for severe COVID-19 illness. The objective of this study was to analyze the characteristics and outcomes of COVID-19 adults who were managed in an outpatient setting compared to patients who required hospitalization at US academic centers.

Methods

Using the Vizient clinical database, Discharge records of adults with a diagnosis of COVID-19 between March 1, 2020 and January 31, 2021 were reviewed. Outcome measures included demographics, characteristics, rate of hospitalization, and mortality, and data were analyzed based on inpatient versus outpatient management.

Results

Among COVID-19 adults, 1,360,078 patients were managed in an outpatient setting while 545,635 patients required hospitalization. Compared to hospitalized COVID-19 adults, COVID-19 adults who were managed in an outpatient setting were more likely to be female (56.1% vs 47.5%, p <0.001), white (57.7% vs 54.8%, p <0.001), within younger age group of 18–50 years (p<0.001) and have lower rate of comorbidities. Mortality was significantly lower in outpatient group compared to hospitalized group (0.2% vs 12.2%, respectively, p <0.01%). For outpatient group, mortality increased with increasing age group: 0.02% (52 of 295,112) for patients 18–30 years and 1.2% (1,373 of 117,866) for patients >75 years. The rate of hospitalization was lowest for age group 18–30 years at 10.6% (35,607 of 330,719) and highest for age group >75 years at 56.1% (150,381 of 268,247).

Conclusion

This analysis of US academic centers showed that 28.6% of COVID-19 adults who sought care at one of the hospitals reporting data to the Vizient clinical database required in-patient treatment. The rate of hospitalization in our study was lowest for the youngest age group of 18–30 years and highest for age group >75 years. Beside older age, other factors associated with outpatient management included female gender, white race, and having commercial insurance.
The sonic performance of Islamic congregational prayer: Ṣalāh in mainstream Egyptian practice1
Authors: Frishkopf Michael
Published: February 2022

Studies of Islamic ritual have focused on the marginal, mystical, sectarian or syncretic. Studies of Islamic ‘music’ have focused on Qurʾanic recitation, the call to prayer and Sufi music. Surprisingly little attention has been paid to sonic aspects of Islam’s basic daily prayer rite, congregational ṣalāh. While ṣalāh’s textual aspects are constrained by discursive specifications, its sound – including timbre, pitch, modality and melody – is relatively free, adapting to the manifold historical, cultural and ritual contexts of the global Muslim community, and enabling prayer to develop greater emotional power. A careful study of the sound of ṣalāh is crucial to understanding the inner meaning and experience of prayer, as well as Islam’s remarkable ability to globalize while remaining deeply affective through an intimate relation to the local soundscape. This article aims to lay the groundwork for the phenomenological and comparative study of ṣalāh, by presenting mainstream Egyptian congregational prayer in detail, demonstrating how it is framed by discursive traditions, while highlighting those ‘unspoken’ sonic aspects which display the greatest contextual variation, and which will underlie future comparative study of meaning and practice.

sensing of urea using mediator enzyme urease on graphite paste electrode modified with silver
nanoparticle (Ag) (PANI/Gr/AgNO3) and without silver nanoparticle(PANI/Gr) and measure the
amperometric response caused by the immobilized urease reaction system. Urease immobilization on
electrode was investigated using an amperometric method and factors like pH after its immobilization
discussed. Prepared materials were characterized by analytical techniques such as ultra violet visible
and SEM analysis. The performance of the developed urea biosensor was evaluated and obtained urea
biosensor exhibited shorter response time (3 s), wider linear range, lower detection limit and good
stability with about 90% of the original response signal retained after 2 months for silver nanoparticle.

Published: February 2022

Poly(L-lactide)-b-polyethylene glycol-b-poly(L-lactide) triblock copolymer (PLLA-PEG-PLLA)/exfoliated boron nitride (BN) composite
films with different boron nitride contents (1, 2, 4 and 6 wt.%) were prepared by a solution-suspension casting method. Differential
scanning calorimetry (DSC), thermogravimetric analysis (TGA), scanning electron microscopy (SEM), X-ray diffractrometry (XRD) and
tensile testing were carried out to characterize the thermal, morphological and mechanical properties of composite films. The DSC and
XRD analyses showed the increasing crystallinity-content of composite films was obtained and their thermal stability as assessed by
thermogravimetric analysis was improved when the boron nitride content was increased until 2 wt.%. Aggregation of boron nitride
particles in composite films occurred when the boron nitride contents were higher than 2 wt.% as observed from SEM. The tensile stress
of PLLA-PEG-PLLA film (25.0 MPa) increased up to 31.6 MPa while strain at break decreased from 76% to 64% when the 2 wt.% boron
nitride was blended. Thus, PLLA-PEG-PLLA/BN composite films have potential to be used as flexible bioplastics.

Organic dyes are frequently used in various industries such as textiles, medicines, plastics, etc. and
contribute as a major source of environmental pollutants, which leads to harmful effects on livings.
Therefore, in this study, a Sn-doped CeO2-Fe2O3 photocatalyst was synthesized using the thermal
decomposition method and applied for the effective degradation and removal of rhodamine B dye
under solar irradiation. The as-synthesized catalyst was characterized by powder X-ray diffraction
(XRD), field-emission scanning electron microscopy (FE-SEM), Brunauer-Emmett-Teller (BET) and
UV-vis diffuse reflectance (UV-vis DRS) techniques. The particle size of the photocatalyst was found
1-2 μm with a high surface area. The band gap energies of the catalyst narrowed to 2.2 eV after the Sn
doping. The doping of Sn4+ ions into CeO2 lattice leads to the enhanced photocatalytic activity of
CeO2-Fe2O3 composite by modified the Fermi levels of catalyst. The catalyst has shown a fast
degradation rate under solar irradiance and is able to perform complete degradation of rhodamine B
dye. The photocatalyst showed the COD removal up to 96% from the dye solution. Further, the scavenger
test revealed the active species hydroxyl (•OH) and superoxide (O2
•−) radical are involved in the
degradation of rhodamine B dye. The complete degradation of rhodamine B dye was studied and
confirmed by high-performance liquid chromatography. A plausible mechanism is proposed for the
degradation process and charge transfer during the degradation.

Renewable energy regulations place a premium on both the use of renewable energy sources and energy efficiency improvements. One of the growing milestones in building construction is the invention of green cottages. Building Integrated Photovoltaic (BIPV) technologies have been proved to aid buildings that partially meet their energy demand as sustainable solar energy generating technologies throughout the previous decade. Curved facades provide a challenge for typical photovoltaics. This study designed, produced, and assessed elastic solar panels supported by flexible photovoltaic systems (FPVS) on a 1 m2 layer. The LabVIEW program recognizes and transmits online data on warm and dry climates. The fill factor was 88% and 84%, respectively, when installed on the silo and biogas surfaces. The annual energy output was 810 kWh on a flat surface, 960 kWh on a cylindrical surface, and 1000 kWh on a hemisphere surface. Economic analysis indicates that the NPV at Flat surface is $ 697.52, with an IRR of 34.81% and an 8.5-year capital return period. Cylindrical surfaces and hemispheres both get a $ 955.18 increase. For cylindrical and hemispheric buildings, the investment yield was 39.29% and 40.47%, respectively. A 20% increase in fixed investment boosted the IRR by 21.3% in the flat system. While the cylindrical system had a 25.59% raise, the hemisphere saw a 24.58% gain

Published: February 2022

Exposure of radioactivity applications should be handled reliably in repositories, radiotherapy rooms, and research centers built with cement-based composites which is generally used as an engineering barrier. The design of certain materials for radioactive exposure requires special handling considering the degradation mechanism of host composite environment and barrier capability. In this study, celestite (SrSO4) minerals having favoring properties for shielding ability was used as aggregates in barrier composites. Strontium mineral-based aggregates were partially replaced with conventional concrete aggregates at different ratios. The high rate X-ray shielding ability and mechanical performance of developed composites were holistically investigated in the presence of real-case radiation. The use of celestite mineral resulted in higher performance both in mechanical and shielding capability of X-rays at a certain level. Microstructural findings also revealed that interface properties of composite paste and celestite minerals were compatible up to 30% of celestite aggregate replacement.

Authors: Andreas Chrysanthakopoulos Nikolaos , Vryzaki Eleftheria
Published: February 2022

Aim: The aim of the current study was to investigate the possible relationship between periodontal status indices and the risk for psoriasis development in a Greek adult population. Subjects and Methods: The study sample comprised 337 psoriasis patients-cases and 337 healthy individuals-controls between 40 to 69 years of age who referred by three dermatology and one dental private practice. Cases and controls completed a health medical and dental questionnaire and underwent an examination of their periodontal status that included the following parameters: Probing Pocket Depth (PPD), Clinical Attachment Loss (CAL), frequency of a regular/irregular annual dental follow-up, and number of missing teeth. Odds ratios (OR’s) and 95% Confidence Intervals (95% CI’s) were assessed using logistic regression model adjusted for possible confounders. Results: The multivariate regression analysis model showed that a higher BMI (p=0.009, OR= 3.154, 95% CI= 1.532-4.028), alcohol overconsumption (p= 0.012, OR= 2.024, 95% CI=1.445-3.435), moderate /severe CAL (p=0.047, 95% CI=2.112, 1.156-3.249), and a number of missing teeth more than four (p=0.027, OR=2.817, 95% CI= 1.267-3.872 and p= 0.016, OR=3.510, 95% CI= 1.350-4.145) were statistically significantly associated with risk for psoriasis development. Conclusion: Individuals with a higher BMI, excessive alcohol consumption, moderate/severe attachment loss and a number of missing teeth more than four were at significantly higher risk for developing psoriasis.

Мета: розробити модельні характеристики техніко-тактичних показників висококваліфікованих плавчинь, що спеціалізуються на дистанції 50 метрів різними способами.

Матеріал і методи: аналіз літературних джерел, хронометрування, відеозйомка, методи математичної статистики. Досліджуваний контингент склали учасниці фінальних запливів Чемпіонатів та Кубків України з плавання на дистанції 50 метрів різними способами. Рівень спортивної кваліфікації спортсменок відповідав званням Майстер спорту України і Майстер спорту України міжнародного класу.

Результати: досліджено вплив показників швидкості плавання, темпу та «кроку» циклу гребкових рухів на результат подолання спортсменками високої кваліфікації дистанції 50 метрів різними способами; визначено найбільш значущі параметри техніко-тактичної майстерності висококваліфікованих плавчинь, в залежності від способу плавання та розроблено їх модельні характеристики.

Висновки: вплив показників швидкості плавання, темпу та «кроку» циклу гребкових рухів на результат подолання спортсменками високої кваліфікації дистанції 50 метрів має характерні особливості в залежності від способу плавання. Найбільш значущими техніко-тактичними параметрами у способі плавання «кроль на грудях» є швидкість на ділянках «15 м – 25 м» та «45 м – 50 м», темп гребкових рухів на відрізку «35 м – 45 м» (R дорівнює -0,60, -0,72 та -0,72 відповідно). В «кролі на спині» результат переважно залежить від швидкого пропливання перших 35 метрів дистанції (показники R знаходяться в межах -0, 57 - -0, 98), а також значень темпу на ділянці «25 м – 35 м» (R= -0,50). Результативність на дистанції 50 м при плаванні способом «брас» знаходиться під впливом показників швидкості подолання відрізків «винирювання – 15 м», «25 м – 35 м» та «45 м – 50 м», темпу гребкових рухів на ділянках «винирювання – 15 м» та «15 м – 25 м», здатності зберігати великий «крок» на відрізках «15 м – 25 м» та «25 м – 35 м» (R на рівні значень -0,88, -0,56, -0,86, -0,55, -0,70, 0,79 та -0,69 відповідно). Результат в способі плавання «батерфляй» більшою мірою зумовлений швидкістю проходження підводної ділянки та другої половини дистанції 50 метрів (R в межах 0,58, - 0,86). Темп і «крок» циклу гребкових рухів тісно корелює з кінцевим результатом на другій половині змагальної дистанції (значення R варіюють від -0,70 до -0,97). Орієнтація на розроблені модельні характеристики найбільш значущих показників техніко-тактичної майстерності спортсменок високої кваліфікації, що мають різну плавальну спеціалізацію, сприятиме вдосконаленню тренувальної та змагальної діяльності у сучасному плаванні.

Ключові слова: спортсменки, 50 метрів, способи плавання, техніко-тактичні показники, взаємозв'язок, модельні характеристики.

Фізична підготовка футболістів на етапі попередньої базової підготовки
Authors: Хоміцевич Дмитро
Published: February 2022

Мета: розглянути теоретичні питання фізичної підготовки футболістів на етапі попередньої базової підготовки.

Матеріал і методи: з метою ознайомлення зі станом досліджуваного питання проведено аналіз та узагальнення наукової, науково-методичної літератури, теоретичних положень щодо фізичної підготовки футболістів на етапі попередньої базової підготовки. Аналізуючи наукові джерела, розглянуто питання за результатами дослідження: використання засобів і методів різної спрямованості у підготовці юних спортсменів. Описані завдання та дидактична мета етапу попередньої базової підготовки. Визначено місце фізичної підготовки юних футболістів у досягненні спортивного результату.

Результати: встановлено, що вибіркове збільшення тренувальних навантажень на всіх етапах спортивної підготовки дітей та підлітків визначається закономірностями розвитку фізичних здібностей. Високий рівень розвитку результатів у юному віці оцінюється як сенситивний період та має основне значення для збільшення засобів впливу на певні фізичні якості. Одні дослідники вважають, що найкращим сенситивним періодом для розвитку сили у юних футболістів є вік 13-15 років, інші - 14-16 років.

Висновки: аналізуючи наукові джерела, за результатами дослідження розглянуто питання: використання засобів і методів різної спрямованості у підготовці юних спортсменів. Організовуючи тренувальний процес футболістів, необхідно враховувати високу інтенсивність обмінних процесів та вікові особливості зростаючого дитячого організму. Відносно низький функціональний розвиток серцево-судинної та дихальної систем у хлопчиків 13–14 років суттєво обмежує можливість виконання тривалих інтенсивних навантажень. В результаті вивчення літератури встановлено, що відповідно до ігрового амплуа косплексна фізична підготовка (з акцентом на швидкісні та швидкісно-силові якості) юних футболістів 13-14 років є актуальним науковим дослідженням.

Ключові слова: фізична підготовка; спортивне тренування; юні футболісти; попередня базова підготовка.

Ekspresi Keberagamaan Komunitas Terang Jakarta dalam Perspektif Popular Culture
Authors: Fadhila Nurul , Hermansah Tantan , Rizky Kiky
Published: February 2022

The term "hijrah" is currently one of the models of religious expression that is trending in some urban youth. Hijrah is seen as a process of someone making a spiritual and religious leap. The "Terang Jakarta" (TJ) Community is one of the "hijrah" communities of the younger generation in Indonesia. TJ facilitates its community in a variety of Islamic study activities that are packaged in a structured, interesting, and up-to-date manner. So that in the TJ community, studying religion becomes fun or popular. This study wants to see how the religious expression of the TJ community is from the perspective of popular culture. The method used in this study is a qualitative method with an interpretive and naturalistic approach. The theory used is Emile Durkheim's religious expression and the theory of popular culture by Dominic Strineti. The results of this study indicate that the "hijrah" with all its supporting attributes which has been a trend is one of the religious expressions shown by the TJ community who adopted popular culture. The popular culture which is identical to something trendy, phenomenal, boisterous, hits, present, seems to lead to the expressions that exist in the management, members, and worshipers as well as various activities of the TJ community. Found many characteristics of popular culture adopted by this TJ community, so that the phenomenon of "hijrah" in this community can be said as part of popular culture.

From Property-Owning Democracy to Generation Rent? Analysing Theresa May’s Housing Rhetoric from the Perspective of the Discourse Historical Approach
Authors: Tihelková Alice , Quinn Novotná Veronika
Published: February 2022

Since the 1920s, British Conservatives pursued the concept of property‑owning democracy, with home ownership viewed as a guarantor of social stability and personal autonomy. However, recent increases in housing costs have made the “British Dream” of home‑ownership more elusive than ever, with renting becoming a lifelong prospect for large swathes of people. Using the Discourse Historical Approach, a method falling within Critical Discourse Analysis, the article analyzes the 2019 housing speech by Prime Minister Theresa May to ascertain whether the changing situation has been reflected in the Conservatives’ housing rhetoric, traditionally driven by a property‑owning ethos. Examining May’s argumentation and language use, it concludes that May’s proclaimed commitment to renewed council house construction represents both a long‑overdue acknowledgement of the housing affordability crisis and a pre‑election strategy to win Labour voters.
Ambiguity and Ambivalence in Buddhist Treatment of the Dead
Authors: Gombrich Richard
Published: February 2022

Every culture is concerned about what happens to people when they die. Even when the dominant religion/ideology provides an answer, an examination of what people actually say and do generally discloses various inconsistences, for example between what they claim to believe and what their actions (notably rituals) suggest that they believe or at least consider possible. In every traditional Buddhist society, adherents are supposed to believe in rebirth, a fate which only those who achieve enlightenment escape, and yet in both the Indian and the Chinese Buddhist traditions people worship and to some extent interact with their dead ancestors and in doing so preserve local pre- Buddhist beliefs and customs. In both traditions there are likewise inconsistencies between what people believe about themselves and what they believe about others, as well as beliefs about how to treat dead parents and how to treat dead strangers. Much in the observable mixture of beliefs and practices may be ascribed to the Buddha himself.
Equal-headed (samasīsin): An Abhidharma Innovation and Commentarial Developments
Authors: Kuan Tse-Fu
Published: February 2022

The suicide accounts of three bhikkhus in sutta literature probably inspired the formulation of a particular type of person who attains Arahantship at death, later designated as an ‘equal-headed’ (samasīsin) person in the Abhidhamma. The Theravāda tends to depict those bhikkhus as non-Arahants before suicide. The Pali commentary explains that they did not attain Arahantship until their deaths and refers to two of them as each being an ‘equal-header’ (samasīsī). By contrast, the (Mūla-)Sarvāstivāda sūtras and Abhidharma portray them as Arahants during their lifetimes. The Sarvāstivādins deny the concept of samasīsin proposed by the Vibhājyavādins, which include the Theravāda and Dharmaguptaka schools. The Pali commentaries provide various explanations and classifications of samasīsin, which have one idea in common: the term signifies the concurrence of two events, and it denotes at least a person who only becomes an Arahant at death, and sometimes someone who becomes an Arahant at the same time as a certain kind of event occurs. The Paṭisambhidāmagga, a quasi-Abhidhamma text, has a chapter that expounds ‘equal-head’ (samasīsa) in an oblique way by enumerating various kinds of sama and of sīsa separately. The Paṭisambhidāmagga commentary tries to make sense of the term samasīsa by associating this textual exposition of sama and sīsa with the more commonly found term samasīsin.
Liberdade Religiosa, Fundamentalismos e Controvérsias acerca da Abertura de Templos em meio a Pandemia do Covid-19 no Brasil
Authors: Gabatz Celso , Zeferino Jefferson , Veras Rogério De Carvalho
Published: February 2022

O propósito desta abordagem é esboçar questões pertinentes à realidade conjuntural brasileira na perspectiva pandêmica, seus desdobramentos e interlocuções com aspectos engendrados por algumas denominações religiosas, sobretudo, evangélicas neopentecostais no cenário atual face à flexibilização da abertura de templos e a realização de cultos. Busca-se aqui, entrementes, ampliar o horizonte crítico e compreensivo sobre as possíveis alternativas que possam (de)limitar um entendimento de bem comum. Interessa-nos, sobretudo, entabular um aprofundamento de como esta conjuntura pandêmica vem repercutindo no panorama brasileiro a partir de determinados valores instrumentalizados no âmbito das sociabilidades religiosas e que, por vezes, consolidam convicções ou preconceitos quem acentuam a própria incapacidade cognitiva em lidar com a realidade. Os resultados indicam que os parâmetros utilizados pelas instituições religiosas se embasam em uma visão tutelar e de correção moral, objetivando reforçar valores que, pretensamente, se coadunariam com o desejo das famílias, dos costumes, de uma ordem política e religiosa enquanto expressão da maioria da população.
