Newborn Pulse Oximetry for Infants Born Out-of-Hospital
Authors: Williams Katie B. , Horst Michael , Hollinger Erika A. , Freedman Jacob , Demczko Matthew M. , Chowdhury Devyani
Published: September 2021

BACKGROUND AND OBJECTIVES

Conventional timing of newborn pulse oximetry screening is not ideal for infants born out-of-hospital. We implemented a newborn pulse oximetry screen to align with typical midwifery care and measure its efficacy at detecting critical congenital heart disease.

METHODS

Cohort study of expectant mothers and infants mainly from the Amish and Mennonite (Plain) communities with limited prenatal ultrasound use. Newborns were screened at 1 to 4 hours of life (“early screen”) and 24 to 48 hours of life (“late screen”). Newborns were followed up to 6 weeks after delivery to report outcomes. Early screen, late screen, and combined results were analyzed on the basis of strict algorithm interpretation (“algorithm”) and the midwife’s interpretation in the field (“field”) because these did not correspond in all cases.

RESULTS

Pulse oximetry screening in 3019 newborns (85% Plain; 50% male; 43% with a prenatal ultrasound) detected critical congenital heart disease in 3 infants. Sensitivity of combined early and late screen was 66.7% (95% confidence interval [CI] 9.4% to 99.2%) for algorithm interpretation and 100% (95% CI 29.2% to 100%) for field interpretation. Positive predictive value was similar for the field interpretation (8.8%; 95% CI 1.9% to 23.7%) and algorithm interpretation (5.4%; 95% CI 0.7% to 18.2%). False-positive rates were ≤1.2% for both algorithm and field interpretations. Other pathologies (noncritical congenital heart disease, pulmonary issues, or infection) were reported in 12 of the false-positive cases.

CONCLUSIONS

Newborn pulse oximetry can be adapted to the out-of-hospital setting without compromising sensitivity or prohibitively increasing false-positive rates.
(Semi)formação, BNCC e escolarização
Authors: Manfré Ademir Henrique
Published: September 2021

Este artigo trata do tema (semi)formação, Base Nacional Comum Curricular (BNCC) e escolarização. É resultado de reflexões e problematizações oriundas da disciplina de Currículo e Escola por mim ministrada junto aos cursos de licenciatura de uma universidade do estado de São Paulo. Tem-se como objetivo geral refletir criticamente sobre as influências que a BNCC traz às políticas de formação docente na atualidade. Além do suporte bibliográfico educacional específico, o artigo ampara-se nas discussões teóricas desenvolvidas por Theodor Adorno em seus textos filosófico-educacionais, discorrendo sobre o conceito de (semi)formação e educação. A análise proposta conclui que a BNCC poderá transformar a estrutura curricular brasileira não pelo caminho da formação cultural (Bildung), mas pelos interesses mercadológicos baseados em aspectos como competitividade, produtividade e empreendedorismo, reduzindo as possibilidades de crítica. Assim, a crítica adorniana à sociedade instrumental emerge como um referencial teórico que contempla a possibilidade de desenvolver em bases diferentes a análise do processo social em que se insere a educação escolar e seus vínculos com a semiformação (Halbbildung).

International Sex Survey: Study protocol of a large, cross-cultural collaborative study in 45 countries
Authors: Bőthe Beáta , Koós Mónika , Nagy Léna , Kraus Shane W. , Potenza Marc N. , Demetrovics Zsolt
Published: September 2021

Background and aims

Limitations of research into sexuality and compulsive sexual behavior disorder (CSBD) include the use of simplistic methodological designs and the absence of quality and unified measurements, empirically supported theoretical models, and large, collaborative studies between laboratories. We aim to fill these gaps with the International Sex Survey (ISS, http://internationalsexsurvey.org/).

Methods

The ISS is a large-scale, international, multi-lab, multi-language study using cross-sectional survey methods, involving more than 40 countries. Participants responding to advertisements complete a self-report, anonymous survey on a secure online platform. Collaborators from each country collect a community sample of adults with a minimum sample size of 2,000 participants with a gender ratio of approximately 50–50% men and women, including diverse individuals with respect to sexuality and gender. The ISS includes a wide range of sociodemographic questions and scales assessing a diverse set of sexual behaviors, pornography use, psychological characteristics, and potential comorbid disorders. Analyses are conducted within a structural equation modeling framework, including variable (e.g., measurement invariance tests) and person-centered approaches (e.g., latent profile analysis).

Discussion and conclusions

The ISS will provide well-validated, publicly available screening tools, helping to eliminate significant measurement issues in the field of sexuality research and health care. It will provide important insights to improve the theoretical understanding of CSBD as well as help to identify empirically supported treatment targets for prevention and intervention programs. Following open-science practices and making study materials open-access, the ISS may serve as a blueprint for future large-scale research in addiction and sexuality research.
An Ethical, Cultural and Historical Background for Cemetery-Based Human Skeletal Reference Collections
Authors: Cardoso Hugo
Published: September 2021

OPEN ACCESS-PAID-CC BY-NC-ND In historically Protestant countries, human skeletal reference collections curated by research institutions have been amassed from bodies dissected by anatomists, typically unclaimed cadavers from morgues and hospitals, or from remains donated to science. In contrast to these anatomy-based and donation-based collections, skeletal reference collections in historically Roman Catholic countries on mainland Europe and in Latin America are for the most part derived from unclaimed remains exhumed from modern cemeteries and ossuaries at the end of the mandated interment period. While much has been written in English about the history, context and ethical framework of anatomy-derived collections, cemetery-based collections have received very little critical attention. The current paper addresses this gap, with particular reference to cemetery-derived collections in Portugal. The cultural and historical context of southern Europe is discussed, particularly Roman Catholic mortuary traditions and the influence of the Napoleonic Code, and these provide the background for an overview of the ethical issues raised by cemetery-derived collections. Here, general principles that should guide the work of human osteologists working in archaeological contexts are relevant, as regards consent, dignity and respect and benefits to science and education, because unlike their anatomy-derived counterparts, cemetery-based collections include individuals who were once buried.
Archaeology in the Shadow of Schindler’s List
Authors: Karski Kamil , Kobiałka Dawid
Published: September 2021

This paper presents some of the preliminary results of non-invasive and invasive archaeological research on the terrain of a former German Nazi labour and concentration camp in P?aszów, a suburb of Kraków. The starting point is a reference to Schindler’s List – a film that is partially about the camp (KL Plaszow in German) and which created a certain social picture of it. This paper discusses the history of archaeological research relating to Holocaust landscapes in Poland, and sketches the historical context related to the opening, functioning, closing and later reusing of the campscape. The last section provides a glimpse into the archaeological field research and its results. The main thesis of this paper is that the history of World War II, including the Holocaust, is transforming in front of our eyes into archaeology. The paper shows how archaeology can play an active and crucial role in discovering, documenting and interpreting material remains related to the Holocaust and its manifold consequences.
The effect of exogenous peroxiredoxin 6 on morphofunctional state of isolated rat kidney
Authors: Gordeeva A. E. , Sharapov M. G. , Novoselov V. I.
Published: September 2021

Objective: to investigate the role of peroxiredoxin 6 (PRX6) in preserving the morphofunctional state of ischemic isolated kidney during perfusion.

Materials and methods. The model of an isolated perfused rat kidney was used. Ischemia time was 5 and 20 minutes, perfusion was 50 minutes. To evaluate the effectiveness of PRX6 at different ischemia times, we used the conventional criteria of kidney function and histological methods.

Results. During short warm ischemia times, exogenous PRX6 improves the morphofunctional state of an isolated kidney during perfusion. During this period, the main criteria for functioning of the isolated ischemic kidney reach acceptable values, renal parenchyma is without severe damage. By the end of perfusion, there was an increase in urine flow rate, glomerular filtration rate, fractional glucose reabsorption, urine urea concentration and proportion of primary urine from 1.5 to 2 times compared with the control lesion. At 20-minute ischemia, the isolated kidney can be recognized as non-viable according to the functioning criteria; the positive effect of PRX6 is leveled.

Conclusion. The use of recombinant peroxiredoxin 6 for preserving the morphofunctional state of isolated kidneys can be an effective approach in preventing ischemia–reperfusion injury.

Published: September 2021

Objective: to find evidence of the existence of distant lymphocytic RNA control of physiological myogenesis as a way to control the muscle tissue regeneration process.

Materials and methods. The study was conducted on male Wistar rats, n=33. In the first part of the experiment, 12 rats were subjected to regular 40-day physical activity (swimming), half of them were intraperitoneally injected 4 times with total RNA isolated from pig spleen lymphocytes at 30 days of age; 6 rats made up the intact control group. In histological preparations of different skeletal muscle groups, the width and cross-sectional area of muscle fibers, the area of nuclei, and the number of myocytes and myosatellite cells were evaluated. In the second part of the experiment, 15 intact rats were injected with the studied xenogeneic RNA and the amounts of ribonucleic acids in peripheral blood lymphocytes, spleen lymphocytes, and skeletal muscles were determined 2 hours and 24 hours after injection.

Results. After the 40- day physical activity, the width of the fibers and the area of myocyte nuclei in the skeletal muscles increased; the absolute number of myosatellite cells and the area of their nuclei did not change. After administration of xenogenic RNA in the trained rats, in addition to an increase in the thickness and cross-sectional area of muscle fibers, the absolute number of myosatellite cells in m. biceps femoris, in m. triceps brachii, and in m. pectoralis major increased 1.4-fold, 1.3-fold, and 1.4-fold, respectively; the area of myosatellite nuclei increased on average by 7%. In intact rats, two hours after xenogeneic RNA injection, the amount of RNA in skeletal muscles remained unchanged, it increased by 19% in spleen lymphocytes, and by 16% in peripheral blood lymphocytes. At 24 hours, the RNA amount in the lymphocytes remained significantly higher than the control values, while in the muscle tissue, it didn’t differ from the control.

Conclusion. Xenogeneic lymphocytic RNA stimulates physiological myogenesis by activating myosatellite cell proliferation.

Respiratory diseases, together with infectious complications and hereditary lung diseases, rank third in international mortality statistics. Today, lung transplantation is a recognized method of treating end-stage lung diseases. However, the number of transplant surgeries performed is not much. This is down to the high requirements on the condition of a potential lung donor and directly on the quality of the donor lung. This has significantly limited the number of optimal donors. Rehabilitation of donor lungs to optimal gas exchange indicators can be achieved and objectively assessed in the course of ex vivo lung perfusion (EVLP). The EVLP procedure is widespread in leading transplantation centers in Europe and North America. It allows to significantly expand the pool of donor lungs, thereby serving a greater number of patients in need of lung transplantation. The possibility of EVLP procedure using publicly available perfusion equipment was demonstrated. The optimized protocol fully demonstrated its reliability and efficiency. The developed perfusion solution had no statistically significant differences in comparison with the Steen SolutionTM, which in the future will serve as an alternative for EVLP procedure.

Ressonâncias do romantismo e da literatura fantástica na psicanálise
Authors: Rabêlo Fabiano Chagas , Dias Reginaldo Rodrigues , Martins Karla Patrícia Holanda , Schollhammer Karl Erik
Published: September 2021

Resumo Mapeiam-se os processos históricos, estéticos e epistêmicos dos séculos XVIII e XIX que associam romantismo, literatura fantástica e psicanálise. Defende-se que o fantástico constitui um importante vetor por meio do qual elementos do romantismo foram incorporados ao modelo psicanalítico de aparelho psíquico. Parte-se da perspectiva de que a assimilação da influência romântica realizou-se de forma seletiva e criativa. Destacam-se alguns pontos de tensões e compromissos entre romantismo e o iluminismo, que foram retomados e transformados pelo fantástico e a psicanálise: as temáticas do amor, da loucura, da sexualidade, das superstições e dos mitos; o questionamento da relação entre o real e suas representações e entre pensamento e consciência; e a valorização do uso retórico da ironia. Aponta-se a abordagem psicanalítica do infamiliar (Unheimliche) como o momento mais sensível dessa interlocução.

ABSTRACT Objective: Analyze risk factors for infection in kidney transplant recipients from deceased expanded criteria donors (DECD) in the first two years of follow-up. Method: This is a prospective cohort study with 466 patients from DECD who underwent kidney transplantation in 2015 and 2016 in Brazil. A total of 551 events were recorded. The largest incidence of infectious events occurred in the first month after kidney transplantation. Cytomegalovirus infection was the most common infectious episode. Results: The incidence rate of infections was 57.1%. Among bacterial infections, only 4% were due to multidrug-resistant microorganisms. The death rate was 3.3% (15) patients. The main cause of death was infectious (73.3%). Hospitalization until the first infection (aOR:1.61), Number of infections in 1 year (aOR:40.16), and Cytomegalovirus infection (aOR:13.84) was risk factors for infection by multidrug resistant microorganisms (MDR). Conclusion: Infection incidence with MDR bacteria was high among kidney transplant recipients from DECD, and the main cause of death was infection. Survival was high among patients with infection.
A cascade of dams affects fish spatial distributions and functional groups of local assemblages in a subtropical river

Published: September 2021

Abstract Dams reduce the longitudinal connectivity of rivers and thereby disrupt fish migration and the spatial distribution of species, impacts that remain poorly studied for some Neotropical rivers from mega-diverse basins. We investigated the spatial distribution of fish species with different trophic and movement/reproductive/size characteristics to assess how functional groups have responded to a cascade of dams on the Uruguai River in southern Brazil. Fish abundance, biomass, and species composition were evaluated at eight locations along the longitudinal gradient. The fish assemblage in the upper stretch was mainly characterized by small and medium-sized species at higher trophic levels, whereas the sites located furthest downstream displayed more medium and large-sized species, including many carnivorous species. Species with high fecundity, seasonal migrants, and catfishes with internal fertilization were common in the river´s middle and lower reaches. Detritivorous species dominated areas distant from the dams. Overall, functional diversity of local fish assemblages was greater in lower reaches. The cascade of dams has impacted the distribution of functional groups of local fish assemblages of Uruguai River. The alteration of functional groups in upper reaches of the river has potential consequences for ecosystem processes and services, such as nutrient cycling and fisheries.
The cost of gold: Mercury contamination of fishes in a Neotropical river food web

Published: September 2021

Abstract In South America, mercury contamination due to gold mining operations is a threat to both biodiversity and human health. We examined mercury (Hg) concentrations in fishes that constitute important subsistence fisheries from mined and non-mined tributaries in the middle Mazaruni River, Guyana. Mercury concentrations and trophic food web structure (based on carbon and nitrogen stable isotopes) were characterized for primary basal sources and 39 fish species representing seven trophic guilds. Fishes collected at mined sites had higher mercury concentrations; piscivores and carnivores had the highest Hg concentrations and exhibited significant Hg biomagnification. Our results showed that medium- to large-bodied fishes commonly eaten by local people contained Hg values that exceed the World Health Organization (WHO) criteria, and pose a health concern for riverine communities along the Mazaruni River that depend on fish as their main source of protein. Further research to determine the sources of Hg contamination and how it affects human health in this neotropical river must become a top priority. In addition, more research on how Hg contamination impacts the fishes themselves and overall aquatic biodiversity is also needed in the Mazaruni River which has both high fish endemism and diversity.

Abstract Mining activities have significantly affected the Neotropical freshwater ichthyofauna, the most diverse in the world. However, no study has systematized knowledge on the subject. In this review, we assembled information on the main impacts of mining of crude oil, gold, iron, copper, and bauxite on aquatic ecosystems, emphasizing Neotropical freshwater fishes. The information obtained shows that mining activities generate several different disturbances, mainly via input of crude oil, metals and other pollutants, erosion and siltation, deforestation, and road construction. Mining has resulted in direct and indirect losses of fish diversity in several Neotropical waterbodies. The negative impacts on the ichthyofauna may change the structure of communities, compromise entire food chains, and erode ecosystem services provided by freshwater fishes. Particularly noteworthy is that mining activities (legal and illegal) are widespread in the Neotropics, and often located within or near protected areas. Actions to prevent and mitigate impacts, such as inspection, monitoring, management, and restoration plans, have been cursory or absent. In addition, there is strong political pressure to expand mining; if – or when – this happens, it will increase the potential of the activity to further diminish the diversity of Neotropical freshwater fishes.
Drastic reduction of the functional diversity of native ichthyofauna in a Neotropical lake following invasion by piscivorous fishes
Authors: Souza Carla Patrícia de , Rodrigues-Filho Carlos Alberto de Sousa , Barbosa Francisco Antônio Rodrigues , Leitão Rafael Pereira
Published: September 2021

Abstract Biological invasions are leading several species to extinction and are projected as a main driver of biodiversity changes in lakes for this century. However, the knowledge of their impacts on the Neotropical ichthyofauna over time remains largely incipient, especially when considering the functional diversity of native communities. Here we aim to identify the effects of non-native species, especially the non-native piscivorous Cichla kelberi and Pygocentrus nattereri, on the functional diversity of the native ichthyofauna of the Carioca Lake, Middle Rio Doce basin, state of Minas Gerais. Using fish occurrence data for eight years from 1983 to 2010 combined with an ecomorphological-trait analysis, we found that while the native species richness dropped to 56%, the functional richness is only 27% of that found before introductions. In other words, more than species, the ichthyofauna suffered an impressive decline in the range of functional traits, which can further have severe impacts on ecological processes within that system. When considering all the components of the current ichthyofauna (native and non-native species), neither taxonomic nor functional richness have changed over time. However, even keeping biodiversity levels, non-native species are not able to fully compensate for the extinct native ones in terms of functions.
Style Evolution: Space and Movement in Longfellow’s Lyrical Poems
Authors: Andreev Vadim
Published: September 2021

ABSTRACT Variance of individual style over time and the tendencies in style evolution are important issues in modern linguistics. This paper investigates how parameters of space and movement categorization were deployed by the famous American poet H.W. Longfellow at different stages of his creative career. The attention is focused on lexical units with spatial meaning. The analysis revealed significant changes in (i) the structure of space, (ii) the ratio of horizontal vs. vertical relations of objects, statics vs. dynamics, and (iii) the role of a human being in poetic space. The early verse represents the world as a balanced unity, which then turns into a more complex system with two strata of reality. At the final stage of Longfellow’s creative career, space in his poetic world is integrated again but now acquires a new structural organisation that is different, to a certain extent, from that of his early period.

Benign Cerebral Edema and Increased Intracranial Pressure (ICP) as Manifestations of COVID-19 Reinfection; A Case Report
Authors: AH Heidary , R Elahi , M Nazari
Published: September 2021

Reinfection with COVID-19 is of great importance since it can substantially affect the future of disease control and vaccine development. COVID-19 can present with diverse neurological, as well as respiratory and gastrointestinal symptoms. Here, we present a rare case of COVID-19 reinfection with neurological manifestations. The patient was a healthy 26-year-old male that had experienced first episode of COVID-19 infection with mild respiratory and gastrointestinal symptoms. In his second episode of infection, he presented to the emergency department with vertigo, vomiting, metamorphopsia, blurred vision, headache, and gate disturbance. Based on the clinical data and imaging studies, the patient was diagnosed with benign cerebral edema and intracranial hypertension. Then, he was treated using intravenous/intramuscular corticosteroids in addition to the supplementary therapies. His symptoms dramatically improved during the next 2 days. No important neurologic or systemic adverse events in response to the treatment were noted. This case reveals that infection with COVID-19, despite positive IgG, does not protect the patient from reinfection. Moreover, COVID-19 reinfection can present with benign cerebral edema and intracranial hypertension, in which case, inflammatory suppression therapy should be considered.

O objetivo deste trabalho foi determinar a qualidade na distribuição de plantas de milho na linha de semeadura, na região do Planalto Médio do Estado do Rio Grande do Sul. O estudo foi realizado no ano agrícola 2018/19, em 23 áreas de cultivo de milho, sendo 14 em sistema irrigado e nove no sistema sequeiro, localizadas em 11 municípios gaúchos. Em cada área foi mensurada a distância longitudinal entre plantas de milho na linha de semeadura, em estádio vegetativo V3. Para tanto, foram avaliados 10 m de plantas, em três repetições, e os dados foram tabulados e distribuídos em: espaçamentos aceitáveis, duplos e falhos. De acordo com classificação proposta na literatura clássica, 56,5% das áreas avaliadas encontram-se em ótimo estado de distribuição de plantas na linha, 39,1% em bom estado, e 4,4% das áreas em estado regular de qualidade da semeadura do milho. Ao observar os dois sistemas de cultivo, as médias de espaçamentos aceitáveis foi de 87,0% para o sistema irrigado, e de 93,8% para o sequeiro. Pode-se concluir que, na maioria das áreas avaliadas, a qualidade da semeadura da cultura do milho na região do Planalto Médio é ótima.

Published: September 2021

Intervenções humanas sobre áreas de mata nativa, em áreas urbanas e em áreas rurais são cada vez mais frequentes. Levando em conta o tamanho da intervenção, os impactos ambientais associados poderão causar grandes prejuízos ao meio biótico e abiótico. A Lei Federal nº 6.938/81, que estabelece a Política Nacional de Meio Ambiente, traz como um de seus instrumentos mais importantes, o licenciamento ambiental. Dentre os diversos tipos de licenciamentos, há o licenciamento florestal que é o instrumento da política florestal do Estado, compreendendo serviços prestados pelo órgão ambiental estadual ou municipal competente. A Resolução CONSEMA 372/2018 define que para as atividades de impacto local o órgão responsável pelo licenciamento é o município. O Rio Grande do Sul conta oficialmente com 804 espécies da sua flora nativa ameaçadas de extinção. Deste modo percebe-se a importância de identificar quais são as espécies da flora que estão sofrendo maior supressão, considerando o licenciamento florestal no âmbito do município de Condor-RS, assim como identificar aspectos referentes ao local de manejo (urbano ou rural), proposta de reposição florestal, e formação dos responsáveis técnicos responsáveis pelo projeto de licenciamento ambiental. Os dados foram extraídos das licenças florestais emitidas pelo órgão ambiental licenciador do município de Condor-RS, através de pesquisa e análise dos alvarás florestais deferidos nos últimos 5 anos (2015 a 2019). O Estudo demonstrou uma intensa exploração de poucas famílias, sendo as famílias Fabaceae e Lauraceae as mais suprimidas. O maior número de indivíduos suprimidos pertence à espécie Araucaria angustifolia.

The first edition of 2015 boasts 13 contributions dealing with a variety of topics. The first article, by Ben Coetzee Bester and Anne Louw, discusses the persistence of the "choice argument", which is based on the rationale that domestic partners who choose not to marry cannot claim spousal benefits, and arrives at the conclusion that legislation should differentiate between registered and unregistered domestic partnerships for the purpose of spousal benefits. Ernst Marais has written two articles on expropriation. In the first he examines the meaning and role of state acquisition in South African law and in the second he deals with the distinction between deprivation and expropriation in the light of Agri South Africa v Minister for Minerals and Energy 2013 4 SA 1 (CC), where the Constitutional Court recently revisited the distinction between the two concepts and held that the distinguishing feature of expropriation is that it entails state acquisition of property, whilst deprivation takes place where there is no such acquisition. The fourth article, by Emeka Amechi, explores the measures taken by the National Recordal System and Disclosure of Origins in leveraging traditional knowledge within the structure, content and conceptual framework of the patent system in South Africa. The South African Companies Act and the realization of corporate human rights responsibilities is the focus of Manson Gwanyanya's article. He comes to the conclusion that the wording of the Act is such that it prevent human rights abuses by companies. In her contribution Melanie Murcott discusses the development of the doctrine of legitimate expectations in South African law and the failure of the Constitutional Court to develop the doctrine even further in the recent case of Kwazulu-Natal Joint Liaison Committee v MEC for Education, Kwazulu Natal. The second last article, which is by Lucyline Murungi, considers the implementation of the UN Convention on the Rights of Persons with Disabilities (2006) to provide for inclusive basic education in South Africa, and the last article, which is by Matome Ratiba, examines the significance of places of worship for Native Americans and demonstrates the valuable lessons South Africa could learn from the earth jurisprudence that has developed in the USA and elsewhere. The first note, authored by Magdaleen Swanepoel, discusses legal issues with regard to mentally ill offenders with specific reference to the cases where mental illness is raised as a defence in criminal cases. The second note, by Michelle Fuchs, deals with recent legal developments relating to the formalities involved when a mortgagee wants to declare immovable property executable to satisfy outstanding debt. The last contribution in this edition is a case note by Elmarie Fourie. She considers the question of what constitutes a benefit in terms of section 186(2) of the Labour Relations Act 66 of 1995, which was examined in Apollo Tyres South Africa (Pty)Ltd v CCMA 2013 5 BLLR 434 (LAC).
ANYONE FOR A GAME OF MONOPOLY™?* A CRITICAL EVALUATION OF THE EVERINCREASING COMMERCIALIZATION OF MAJOR SPORTING EVENTS PART 1: AN OVERVIEW OF AMBUSH MARKETING IN SPORT
Authors: Andre M Louw  , Daniel Areias
Published: September 2021

This is the first part of a three-part article which critically evaluates the everincreasing trend of commercial monopolization of major sporting events by sports governing bodies and their commercial partners such as sponsors. This first part of the article will provide a background description of the various forms of protection against ambush marketing of events, as an area where such increased calls for the creation and ring-fencing of commercial rights to events have been (and remains) at the forefront. The second part of the article will evaluate the legitimacy of such protections (especially in the form of special legislation) critically in the context of such commercial monopolization, with reference to constitutional, intellectual property and competition-law arguments in the South African context, and will conclude with some observations regarding current developments elsewhere.

Basketball Skill Achievements: Comparison between Technical Approach and Tactical Approach based on Physical Fitness Level
Authors: Nur Lutfi , Malik Arief Abdul
Published: September 2021

Learning approaches, such as tactical approach and technical approach, have been widely discussed for promoting physical activity in physical education learning. The application of a suitable learning approach becomes an important issue related to different fitness level of individual. The purpose of this study was to investigate the results of basketball skill learning by applying the learning approaches based on the physical fitness level of adolescent students. A 2 x 2 factorial design (ANOVA) was applied in this study. Forty junior high school male students were involved in this study. They were divided into 4 groups, including 2 high physical fitness groups and 2 low physical fitness groups by applying the tactical approach and technical approach. This study used the Indonesian Physical Fitness Test (TKJI) instrument for the junior high school level and basketball skill test instruments, including passing, shooting, and dribbling tests. The results showed that, overall, students who received the tactical approach were better than students who received the technical approach. In the high physical fitness student group, the tactical learning approach showed a significant impact compared to the technical approach. However, in the students with low physical fitness group, the technical approach had a better effect on the students' basketball skills. It concludes that the two learning approaches are proven to be able to improve the outcomes of basketball skill learning. For that reason, it is recommended to teach basketball skills using a tactical approach to students with good physical fitness. However, if students have low physical fitness, it is suggested that technical learning approaches is given.

Objetivos: identificar sob a ótica do enfermeiro o cuidado ao idoso com doença de Alzheimer e principal desafio para realização do mesmo. Método: estudo descritivo-exploratório, de abordagem qualitativa, desenvolvido com 15 enfermeiros da clínica médica. Os dados foram coletados no período de agosto e setembro de 2017, por meio de entrevistas e submetidos à Análise de Conteúdo. Resultados: emergiram-se quatro categorias temáticas: Compreensão dos enfermeiros sobre a doença de Alzheimer; Assistência ao idoso e família; Ausência de capacitação; e Rejeição dos familiares diante do diagnóstico. Discussão: caracterizar o desempenho do enfermeiro quanto o cuidado ao idoso com DA está relacionado às mesmas atividades paralelas ao planejamento diário de sua rotina. Conclusão: os enfermeiros possuem um conhecimento limitado a respeito da doença. Esse déficit de conhecimentos pode trazer consequências na assistência ao idoso com Alzheimer, assim como para os familiares.

Published: September 2021

This work is dedicated to the modeling methodology of a viscous fluid flows with the lattice Boltzmann method on graphic processors based on the technology of images rendering in web browsers WebGL. A two-dimensional nine-velocity LBM model (D2Q9) with a collision integral in a Bhatnagar-Gross-Kruk approximation form is shown. The possibilities of calculation acceleration using WebGL technology is described, namely features of using textures to contain values of some physical quantities in numerical algorithms and using fremebuffers to storage the textures, influence of the texture parameters on the numerical algorithms, features of shaders programming. The questions of shader programs using for carrying out stages of physical modeling were considered. The proposed methodology was used to develop an original web program for modeling of classical test problems. Simulations of the Poiseuille flow in a plane channel and the flow around a circular cylinder in a plane channel were performed. The obtained results were compared with the results of calculations performed in the original verified modeling program based on the lattice Boltzmann method and in the Comsol Multiphysics package with the finite element method. Comparisons of the values of the velocity magnitude showed the consistency of the obtained results with the data of other numerical experiments. The analysis of computational speed in comparison with modeling using the optimized algorithm of a method with use of the technology of parallel calculations on CPU OpenMP in the original program is carried out. It is shown that the acceleration of calculations depends on the number of cells of the calculation grid. The results of the fluid flow modeling around a circular cylinder at Re = 1000 are demonstrated, which are obtained 30 times faster than with the calculations obtained with optimized lattice Boltzmann method and OpenMP technology.
