Baummikrohabitate im Schweizer Wald und im Buchenurwald Uholka-Schyrokyj Luh
Authors: Brändli Urs-Beat , Abegg Meinrad , Düggelin Christoph , Traub Berthold
Published: September 2021

Habitatbäume sind eine Schlüsselkomponente der Waldbiodiversität. Seit rund 20 Jahren ist die Bedeutung von Baummikrohabitaten (BMH) als Lebensraum für Tausende teils hochspezialisierte Arten bekannt, und BMH finden zunehmend Eingang ins Waldmonitoring. Mit der Einführung der ersten europäischen Typologie der BMH verfügen das Schweizerische Landesforstinventar (LFI) und die Inventur im Buchenurwald Uholka-Schyrokyj Luh in der Ukraine als erste Grossrauminventuren über repräsentative Referenzdaten. Auch wenn die Reproduzierbarkeit bei einigen BMH-Typen eher schlecht ist, sind nach drei Erhebungsjahren des fünften LFI doch erste aufschlussreiche Vergleiche möglich. Im Schweizer Wald weisen 60% der stehenden lebenden Bäume ab 12 cm Brusthöhendurchmesser mindestens ein BMH auf. Am häufigsten in Stück pro Hektare sind solche mit Flechtenbewuchs (73), Moosbewuchs (67), Stammfusshöhlen (53), Kronentotholz (47) und Harzfluss (37), selten jene mit tiefen Mulmhöhlen (4), Spalten (1), Spechtbruthöhlen (1) und Pilzfruchtkörpern (1). Am geringsten ist die Anzahl BMH-Typen an Tannen (0.6), am grössten an Arven (1.6), Eichen (1.4) und Kastanien (1.3). Generell nimmt die Anzahl verschiedener BMH-Typen mit zunehmendem Baumdurchmesser zu. Die BMH-Dichte variiert je nach Waldfunktion, Waldeigentum, letzter Nutzung, Höhenlage und Geländeneigung. Die tiefen Werte im Mittelland und im östlichen Jura könnten Handlungsbedarf indizieren. Die BMH-Dichte an lebenden Bäumen ist im Schweizer Buchenwald gleich gross wie im Buchenurwald Uholka-Schyrokyj Luh. Allerdings sind tiefe Baumhöhlen, Rindentaschen, Kronentotholz und mehrjährige Pilzfruchtkörper im Buchenurwald häufiger, im Buchenwald dagegen Dendrotelme, Moos- und Efeubewuchs. Der wohl wichtigste ökologische Unterschied liegt im Totholzvolumen, das im Buchenurwald insgesamt fast dreimal so hoch ist wie im Buchenwald, bei den Dürrständern sogar fast sechsmal so hoch.
Waldleistungen und Störungsanfälligkeit: eine modellbasierte Multikriterienanalyse
Authors: Temperli Christian , Blattert Clemens
Published: September 2021

Der Schweizer Wald erbringt verschiedene Leistungen: Insbesondere dient er der Holzproduktion und dem Schutz gegen Naturgefahren, speichert Kohlenstoff und beherbergt eine vielfältige Tier- und Pflanzenwelt. Die gleichzeitige Erbringung dieser Waldleistungen kann jedoch zu Zielkonflikten führen. Zusätzlich beeinflussen Störungsereignisse wie Windwurf und Borkenkäferbefall die nachhaltige und langfristige Bereitstellung der Waldleistungen. Hier stellen wir eine Arbeit vor, die mithilfe von Simulationen des Modells MASSIMO Waldleistungen und Störungsanfälligkeit anhand von Indikatoren in die Zukunft projiziert und potenzielle Zielkonflikte und Synergien mittels einer Multikriterienanalyse bewertet. Dazu wurde die Waldentwicklung ausgehend von Daten des Landesforstinventars (LFI) unter vier Bewirtschaftungsszenarien für die Jahre 2016 bis 2106 unter konstantem Klima simuliert. Über alle Waldleistungen und die ganze Schweiz gesehen schnitt das Business-as-usual- Szenario am besten ab. Jedoch wurden dabei die möglichen Holznutzungspotenziale nicht ausgeschöpft, und es bestanden Zielkonflikte zwischen Biodiversitätsförderung und Kohlenstoffspeicherung. Am meisten Kohlenstoff konnte mit einem Szenario gespeichert werden, unter dem Nadelbäume gefördert und viel Holz geerntet wurde. Dies, weil so viel Kohlenstoff in Holzprodukten gebunden und erdölbasierte Materialien ersetzt werden konnten. Allerdings führte der höhere Nadelholzanteil (vor allem Fichten) zu einer höheren Störungsanfälligkeit gegenüber dem Borkenkäfer. Generell sank die Anfälligkeit gegenüber Sturm und Borkenkäfer bei Szenarien mit verstärkter Holznutzung. Dies führte jedoch aufgrund von weniger Tot- und Altholz zu einem Zielkonflikt mit der Biodiversitätsförderung. Die Störungsanfälligkeit war in LFI-Probeflächen mit hoher Schutzwirkung gegenüber Lawinen und Steinschlag leicht erhöht. Der gewählte Ansatz brachte neue Erkenntnisse zu den Wechselwirkungen zwischen Waldleistungen und Störungsanfälligkeit und bietet Grundlagen für die Entscheidungsunterstützung in der Waldplanung und der Waldpolitik auf regionaler und nationaler Ebene.
Dynamique évolutive de la forêt au Sud des Alpes suisses

Published: September 2021

La surface forestière du Sud des Alpes suisses a plus que doublé en 120 ans, avec une accélération importante de cette croissance après la Seconde Guerre mondiale. En utilisant les données de l’Inventaire forestier national (IFN), l’article décrit la structure, la composition et l’évolution des forêts de cette région, en distinguant les forêts établies avant 1940, celles formées entre 1940 et 1985, ainsi que celles établies après 1985. En raison de difficultés structurelles et environnementales, la forêt a évolué de manière naturelle depuis plusieurs décennies sans véritable gestion régulière. Cette évolution conduit au vieillissement progressif des forêts de plus en plus denses et sombres, qui finit par favoriser les essences intermédiaires et surtout finales, en particulier le hêtre. Les espèces pionnières, en revanche, sont en fort déclin dans les forêts établies depuis longtemps et pour elles – le bouleau et le mélèze en particulier – les zones boisées de formation récente représentent un refuge important. En outre, les analyses mettent en évidence la rareté de la régénération, particulièrement importante pour garantir la stabilité des forêts à moyen et long terme, mais elles montrent aussi l’effet bénéfique des interventions sylvicoles sur l’abondance du rajeunissement. Les extrêmes climatiques, en particulier les sécheresses de plus en plus fréquentes, intensifient encore la concurrence entre les espèces. Dans ce cadre, le châtaignier – essence symbolique du Sud des Alpes – est en grande difficulté, surtout dans les stations fortement exposées au soleil et à la pénurie d’eau. Les résultats de l’IFN montrent effectivement une forte mortalité du châtaignier au cours des trois dernières décennies.

Authors: Indriani Indriani
Published: September 2021

Abstract

Hypertension is the first of the fifteen diseases in Gorontalo city which mostly affects the elderly, with a total of 2240 people. One of the efforts to control the risk of increased hypertension is through family support so that the elderly at the age who are no longer productive can still improve their health status. This study used an observational research design with a cross-sectional approach. Sampling in this study was carried out by means of simple random sampling with the criteria of the elderly who came for treatment at health centers and were willing to be respondents, namely as many as 33 respondents. The results showed that the correlation between family support and elderly behavior in controlling hypertension using the chi square test got a value of ρ = 0.025 <a = 0.05. The conclusion of this study is that there is a significant relationship between family support and the behavior of the elderly in controlling hypertension. Support from family can motivate the elderly to maintain their quality of life in old age.

mudanças efetivadas pela lei 13.964/2019 (pacote anticrime) no Instituto do Livramento Condicional
Authors: Cavalcanti Barros Ribeiro Jéssica
Published: September 2021

Resumo: O objetivo do artigo é analisar o instituto do Livramento Condicional após a aprovação da Lei 13.964/2019, conhecida como “Pacote Anticrime”. Trata-se de uma pesquisa descritiva, cuja metodologia empregada consiste em pesquisa bibliográfica, principalmente na área jurídica de Direito Penal, utilizando-se também de análise jurisprudencial. Ao final, conclui-se que a principal alteração efetivada pela Lei 13.964/2019 encontra-se no art. 83, III do CP, sobretudo na alínea b), que dispõe que “o não cometimento de falta grave nos últimos 12 (doze) meses pelo condenado é requisito para a concessão de Livramento condicional”. Essa mudança legislativa poderá acarretar, até mesmo, em alteração de entendimento jurisprudencial no âmbito do STJ, pois que aumentaram-se os requisitos para a concessão do Livramento (ou seja a lei é mais gravosa), gerando dúvidas na interpretação da Súmula 441, que dispõe que “o cometimento de falta grave, por falta de previsão legal, não interrompe o prazo para aquisição do benefício do livramento condicional”.

Published: September 2021

A propriedade intelectual – fruto da criatividade e conhecimento - é utilizada muitas vezes no mercado para posicionar produtos e serviços, expandindo assim o mercado que eles possam estar inseridos. Estas manobras de mercado tornam as atividades das empresas muitas vezes suscetíveis a atos de concorrência desleal, sendo que neste contexto, o Trade Dress designa a identidade visual de um produto, serviço ou de uma empresa, abrangendo cores, rótulos, formas e disposição dos elementos constantes na embalagem, além dos componentes que formam a aparência externa de um estabelecimento. Estas características são passíveis de proteção enquanto marcas, desenhos industriais ou direito autoral. Nos casos em que o Trade Dress não é protegido enquanto direito autônomo, ainda é possível tutelá-lo para coibir atos desleais entre concorrentes. Este artigo visa a analisar aspectos concernentes à proteção jurídica do Trade Dress fazendo comentário do caso envolvendo as empresas “Camarões do Mucuripe” e “Camarões Potiguar”.
Inteligência artificial e a não neutralidade dos algoritmos sobre os “corpos dóceis”
Authors: Souza Mello Breno Cesar de
Published: September 2021

O mundo contemporâneo vem sendo alterado pelo avanço tecnológico, principalmente, pelo desenrolar das novas ferramentas pautadas pela Inteligência Artificial (IA). O presente trabalho busca destacar que, nesse contexto de grandes mudanças, o uso incorreto da IA pode potencializar, muitas vezes, o cenário de violações aos direitos humanos. Dessa forma, o estudo terá como ponto de inferência a assertiva de que nem sempre os algoritmos apresentam pontos de neutralidades, já que tais refletem os aspectos culturais dos programadores que, por sua vez, estão a serviço da cultura hegemônica – branca, heteronormativa, machista e marcada por grandes estratificações sociais.

Published: September 2021

O trabalho almeja analisar a aplicação da pena privativa de liberdade na contemporaneidade. O presente estudo tem como objetivo geral definir se a pena de prisão, nos moldes em que é aplicada, pode ou não ser considerada uma evolução frente aos suplícios narrados por Foucault (na obra “Vigiar e Punir”). Salienta-se que o artigo tem a pretensão de conceder ao leitor uma visão crítica do tema, explorando pertinentes pontos acerca do objeto em análise. Para tal, realizou-se pesquisas bibliográfica e documental a partir de obras relacionadas ao tema, além de a própria pesquisa se valer de registros, obtidos pela Defensoria Pública do Rio de Janeiro, da Penitenciária Plácido de Sá Carvalho. Entre as conclusões obtidas por meio deste trabalho, destaca-se que a pena privativa de liberdade em nada evoluiu se comparada aos espetáculos à época, pois o sistema penal continua eliminando, cada vez mais, valores afetos à pessoa humana.

O presente trabalho tem o intuito de demonstrar a evolução da inteligência artificial no campo jurídico, tendo como principal objetivo analisar questões emblemáticas sobre ética, personalidade jurídica e responsabilidade civil que norteiam o seu desenvolvimento. Este é um tema totalmente inovador ao meio social, dessa forma, é fundamental realizar um estudo jurídico prévio a respeito da sua utilização. Para isso o trabalho contou com pesquisa qualitativa em artigos, livros, sítios da internet, revistas e jornais.  Feitas as análises necessárias foi possível concluir que o uso dessa nova tecnologia vai reestruturar as bases ontológicas e epistemológicas do direito atual, de modo a reformular conceitos básicos já existentes na sociedade como de pessoa e personalidade, além de criar novas perspectivas e concepções sociais. Consequentemente, a melhor alternativa é capacitar os juristas para que possam entender o funcionamento dessa tecnologia, permitindo assim, a coexistência entre os humanos e as máquinas no mesmo ambiente.
On the Global Contrasting Temperature-Precipitation Phase Mechanisms in the Last Century
Authors: Dimri A.P. , Kumar P. , Maharana P.
Published: September 2021

Global precipitation patterns have changed compared to the before 1960 (pre-industrial period). By now the temperature has risen by approximately 1°C. The atmospheric heat-retaining constituents have been raised by human-induced activities. It is influencing the composition of the atmospheric gases and water vapour leading to tropospheric energy budget imbalance affecting atmospheric pressure systems. Increased atmospheric warming leads water holding capacity to rise. Such changes insinuated contrasting phases: decreased (increased) temperature- increased (decreased) precipitation in the last century. Mechanisms of these in- and out- phases are investigated. In the total four (two colder-wet and two warmer-dry) global conditions are observed. These time slices indicate a gradual increase in global temperature and a decrease in precipitation. Clausius-Clapeyron relation suggests abrupt warming and increased water vapour pressure in recent decades. In addition, the global climate system is shifting towards abnormal warm-wet or warm-dry conditions. Further, contrasting changes in global precipitation have been seen, in particular after 1960 (post-industrial period). It is significantly noted that there has been a global contrasting temperature-precipitation phase mechanism in the last century.

Published: September 2021

BACKGROUND: COVID-19 has affected many countries in the world and has been known as one of the fast-spreading viruses in recent history. OBJECTIVE: Our aim is to reveal the level of anxiety and burnout, attitudes, thoughts, and behaviors of healthcare professionals about COVID-19 in Turkey. METHODS: The individuals included in the study answered seven questions containing demographic information, 27 questions determining their views and perspectives on COVID-19. Anxiety level was measured by Beck Anxiety Scale (BAI), and State Anxiety Inventory (SAI); burnout was measured by Maslach Burnout Inventory (MBI). RESULTS: We included 66 health staff (50 female, 16 male) whose mean age was 31.71±5.18 years (22–46 ranged). Twenty-two (33.3%) of the participants worked on the COVID-19 frontline while 44 (66.6%) of them worked on usual wards. We found that participants’ anxiety was at a moderate level in BAI (mean: 14.00±12.66). The mean of the SAI was 49.93±13.06. MBI subscales were low. We found that there was a significant difference in BAI between COVID-19 frontline healthcare professionals and those who worked on the usual wards (p = 0.01). CONCLUSIONS: It is important to consider the level of anxiety and burnout in all healthcare professionals and to help them to protect their mental health.
Social validity of work ability evaluations and official decisions within the sickness insurance system: A client perspective
Authors: Karlsson Elin A. , Sandqvist Jan L. , Seing Ida , Ståhl Christian
Published: September 2021

BACKGROUND: Studies of the social validity of work ability evaluations are rare, although the concept can provide valuable information about the acceptability, comprehensibility and importance of procedures. OBJECTIVE: The aim of this study was to explore clients’ perceptions of social validity of work ability evaluations and the following official decisions concerning sickness benefits within the Swedish sickness insurance system. METHODS: This was a longitudinal qualitative study based on interviews with 30 clients on sick leave, analyzed through deductive content analysis. RESULTS: Clients’ understanding of the evaluation was dependent on whether the specific tests were perceived as clearly related to the clients’ situation and what information they received. For a fair description of their work ability, clients state that the strict structure in the evaluation is not relevant to everyone. CONCLUSION: The work ability evaluations indicate low acceptability due to lack of individual adaptation, the comprehensibility varied depending on the applicability of the evaluation and information provided, while the dimension ‘importance’ indicated as higher degree of social validity. The official decision about sickness benefits however was considered unrelated to the evaluation results, lacking solid arguments and sometimes contradictory to other stakeholders’ recommendations indicating poor social validity.

AbstractElectric vehicles become the alternative to solve the climate change and global warming problems by providing a more eco-friendly and sustainable source of energy. As the demand for sustainable vehicles increased, the functionality of batteries become crucial. One of the important aspects inside the batteries is nickel. Nickel plays a big role in lithium-ion batteries by delivering greater amounts of energy density with a higher storage capacity, which means it provides bigger efficiency to the batteries. Yet, the attempt of optimizing nickel extraction remains a challenge. Therfore, nickel extraction process of lateritic ore with high efficiency is investigated by using hydrometellurgy process, specifically the iron removal process in atmospheric condition in mixed hydroxide precipitates (MHP) route.The reagent solution of (20% w/w and 25%  w/w) calcium carbonate (CaCO3) at pH (1, 2, 3) were utilized as additive in this process. The precipitates resulted from PLS were characterized by x-ray diffraction (XRD) and Scanning Electron Microscopy - Energy Dispersive X-Ray (SEM–EDS), while the filtrates were investigated by Inductively Coupled Plasma-Optical Emission Spectrometry (ICP-OES). Analysis based on precipitates demonstrates that the acid neutralization process took place with a sufficient amount of iron in the precipitates with the least amount of nickel. In addition, all pH and concentration of precipitates qualitatively illustrate the same neutralization process involving calcium and sulfur. From the results of filtrate through ICP testing in this study, pH 1 for both 20% and 25% concentration provides the lowest recovery rate alongside the smallest ppm compare to pH 2 and 3; thus, the iron precipitates in the formation of iron sulfide and/or iron sulfate. Overall, the optimum parameter is 25% of calcium carbonate, pH 1, 90oC for 2 hours of agitation to reduce the amount of iron in the solution.

For a long time, any heart-based injury was an off-limits area for surgeons; a patient with a traumatic cardiac injury was doomed to die. Little more than one hundred years have passed since the first surgical correction of a penetrating cardiac injury and there is still a high rate of mortality, despite the medical advances. We present the case of 6 patients with penetrating cardiac injuries that were repaired at a third level hospital of Mexico, alongside relevant findings on the literature about the topic. From 2019 to 2020, an incidence of 6 patients with penetrating cardiac injuries was present; all men aged 30 years or older. The etiology of 4 (67%) patients was stab wounds and 2 (33%) gunshot wounds. Left anterolateral thoracotomy was used on 5 (83%) patients and midline sternotomy on 1 (17%) patient. 2 (33%) injuries on the left ventricle presented along with coronary arteries injuries. Left ventricle and right atrium injuries presented each 50% of mortality. The mortality was of 33%, 1 patient died due to intraoperative complications and another one due to massive cerebral infarction and polyuric syndrome because of diabetes insipidus. There is a long path ahead of the surgical field on this topic and further to be analyzed. An excellent tool for cardiac tamponade diagnosis due to penetrating cardiac injuries is cardiac ultrasound, therefore it should be used on every hemodynamic unstable patient in the context of PCI. Definitively, time is of the essence, and the survival of patients depends on immediate transport to a hospital and an opportune surgical intervention.

Authors: Hussain Shabnum , Padil Preethi Shree , Masoodi Ibrahim , Telis Rouchell , Pai Vidiya
Published: September 2021

Background: Type of antibodies produced by an individual in response to any autoimmune disorder varies from person to person and from place to place depending upon the immune status of the patient .

Aims & objectives:  

To describe the fluorescence pattern of ANA by indirect immunofluorescent assay in patients with autoimmune diseases and compare it with their ANA profile.

Material & Methods:

In this retrospective study (January 2018 to December 2020) we reviewed the case records of 96 patients with different autoimmune diseases. Their demographic details like age, gender, family history, presenting symptoms were tabulated. We compared their respective ANA test reports (Pattern and profile)

Results:  Data of   96 patients (20 male and 76 females) was analyzed. The age range of the study cohort was  10- 77 years , mean age was  39.53  .There were  23(23.9%) patients with SLE, 34(35.4%) with MCTD . 6 (6.2%) Sjogren's syndrome. Glomerulonephritis was present in 7(7.2%) patients and Rheumatoid arthritis in 4 (4.1%) . All study participants had ANA positive and ANA pattern was seen as homogenous in 34(35.4%), speckled 45(46%), nuclear pattern was seen in 33(34.9%) . LIA was found to be significantly positive in sjogren's disease while in SLE only 22 patients had positive LIA. None of our Rheumatoid arthritis patients had positive LIA  

Conclusion:  We conclude that it is better to restrict performing line immunoassays as these are expensive and use ANA-IIF fluorescent patterns to predict presence of autoantibodies to diagnose an autoimmune disease.

Published: September 2021

Embora as discussões sobre a possibilidade de educação online no ensino fundamental e médio no Brasil tenham entrado na esteira do debate teórico, ainda se encontra uma grande resistência. No entanto, o contexto pandêmico não trouxe alternativas, levando milhares de alunos ao isolamento social por mais de um ano. Este contexto fez com que professores do ensino fundamental e médio tivessem que se adaptar às novas tecnologias, demonstrando então a necessidade de se preparar para atuar no ensino de aprendizagem remoto. A pergunta norteadora desse material foi: Como os professores de ciências biológicas podem se preparar e quais ferramentas básicas devem conhecer para preparar suas aulas online? Assim, o objetivo geral foi realizar indicações que os professores devem conhecer para preparar suas aulas online. A metodologia adotada foi a exploratória através de revisão de literatura. As principais indicações foram que os professores precisam buscar conteúdos diversificados na preparação de aulas para adotar estratégias de motivação junto aos seus alunos, adotando cuidados com a questão da linguagem, áudio e luz na produção das aulas. Por fim, caberá ao professor reconhecer as diversas ferramentas e recursos como: Youtube, Instagram, Filmes, Jogos, e demais subsídios, a fim de que haja uma aproximação entre o ensino da biologia e a realidade do aluno.

Sebbene le discussioni sulla possibilità di istruzione online nelle scuole elementari e superiori in Brasile siano entrate nella scia del dibattito teorico, c’è ancora una grande resistenza. Tuttavia, il contesto pandemico non ha portato alternative, portando migliaia di studenti all’isolamento sociale per più di un anno. Questo contesto ha indotto gli insegnanti delle scuole elementari e superiori ad adattarsi alle nuove tecnologie, dimostrando così la necessità di prepararsi a lavorare nell’insegnamento dell’apprendimento a distanza. La domanda guida di questo materiale era: come possono prepararsi gli insegnanti di scienze della vita e quali strumenti di base dovrebbero conoscere per preparare le loro lezioni online? Pertanto, l’obiettivo generale era quello di eseguire indicazioni che gli insegnanti dovrebbero conoscere per preparare le loro lezioni online. La metodologia adottata è stata esplorativa attraverso la revisione della letteratura. Le principali indicazioni erano che gli insegnanti devono cercare contenuti diversificati nella preparazione delle classi per adottare strategie motivazionali con i loro studenti, adottando cura con il tema del linguaggio, dell’audio e della luce nella produzione delle classi. Infine, toterrà all’insegnante riconoscere i vari strumenti e risorse come: Youtube, Instagram, Film, Giochi e altri sussidi, in modo che ci sia un’approssimazione tra l’insegnamento della biologia e la realtà dello studente.

Disruptions of [In](ter)dependence as Methods for Choreographic Praxis
Authors: Piquero Alvarez Lucia
Published: September 2021

This article studies how different forms of disruption of creative exchanges between music and dance can be conceptualised. These explorations are the results of two editions of the choreographic research project Estancias Coreográficas (Spain, 2017 and 2018). The sources of these explorations are varied: from participants’ questionnaires to a symposium on music and dance. The article proposes a conceptualisation of the possible collaborations between contemporary forms of music and dance, and, at the same time, discusses the conceptual practice which is constituted in this collaboration in itself. Exploring the documentation of two intensive research processes in which music and dance were put in relation—something which is common in choreography but perhaps not so often systematically studied in practical environments—the article proposes that through the conceptualisation of the many forms, concepts, and possibilities that these collaborations offer, the moment of exchange in itself emerges as a conceptual practice. This, of course, makes the conceptualisation somewhat vague and complicates the exploration.       In this context, the concept of disruption becomes more enticing as an understanding of artistic exchanges. There is a sense in which the interactions between choreographers, composers, researchers and practitioners can be understood as a form of “disordering”.
Performance Review: Coronavirus Time Capsule Project
Authors: Glarin Anna
Published: September 2021

The Coronavirus Time Capsule features the voices and experiences of over 3,000 teenagers from all over the world. Through weekly themes young people from youth theaters and youth organisations film themselves and their lives, documenting the trials and tribulations of life in lockdown. All material is edited and presented on Company Three’s website, alongside a Best Bits compilation video. This review considers the context in which this piece of performance art was created; during a global pandemic in which the voices of young people are rarely heard. As the title of the project suggests, its aim was to create a way, i.e., a time capsule, for teenagers to record and remind themselves about how and what they felt during the pandemic in years to come. However, this review argues the potential wider impact a virtual project of this scale can have and what we as theater-makers can learn from it.

Efeitos da prática de artes marciais na aptidão física e características comportamentais de pessoas com deficiência intelectual: uma revisão sistemática
Authors: Machado Thaynara , Santana Luvanor , Oliveira Lúcia Inês Guedes , Oliveira Saulo Melo
Published: September 2021

Introdução: Pessoas com deficiência intelectual (DI) normalmente apresentam limitações no campo da interação social, e também podem ser acometidos por doenças crônicas. A atividade física e o esporte exercem importantes reduções nos riscos de desenvolver doenças, contudo, algumas modalidades ainda carecem de informação sobre sua efetividade, tais quais as artes marciais.

Objetivo: Apresentar os efeitos relacionados a prática de artes marciais para pessoas com deficiência intelectual.

Método: Uma busca sistemática em seis bases de dados foi realizada por dois avaliadores independentes. Os estudos deveriam trazer informações claras sobre o público com deficiência intelectual estudado além das características que compunham as intervenções selecionadas. A qualidade dos estudos foi avaliada pela escala PEDro.

Resultados: Após administração dos critérios de inclusão/exclusão 16 estudos foram selecionados (karatê: seis; judô: cinco; taekwondo: dois; taichi: dois e artes marciais mistas: um), totalizando 310 pessoas com deficiência intelectual avaliadas. Os tipos de deficiência intelectual investigados foram Síndrome de Down (n=21), deficiência intelectual grave e moderada (n=45), transtorno do espectro autista (n=135), deficiência intelectual não especificada com Coeficiente intelectual <70 (n=66), deficiência intelectual “educável” (n=32) e epilepsia (n=11). Os principais resultados apontam para melhoria em aspectos da aptidão física e também do desempenho motor. Aspectos de socialização e do comportamento apresentam resultados conflitantes.

Conclusão: Existem efeitos positivos oriundos da prática de artes marciais, contudo variáveis comportamentais ainda carecem de evidência em pessoas com deficiência intelectual. A baixa qualidade metodológica dos estudos releva a necessidade de mais pesquisas de qualidade, randomizadas e controladas, e incluindo outras artes marciais acessíveis ao público com deficiência intelectual.

Authors: Pérez Monzón Raquel , Jiménez-Alfageme Rubén , Sospedra Isabel , Sánchez-Oliver Antonio Jesús , Dominguez Raúl , Martínez-Sanz José Miguel
Published: September 2021

Introducción: El uso de suplementos deportivos (SD) es muy común entre los atletas y durante los últimos años la prevalencia de su consumo ha ido aumentando. Sin embargo, no todos los SD proporcionan los beneficios que se busca cuando se decide consumir este tipo de sustancias. Es por ello que las entidades científicas han puesto su foco en la evaluación de SD y se han creado clasificaciones en función de la evidencia científica, como la que ha propuesto el Instituto Australiano del Deporte (AIS). Los remeros de élite realizan sesiones de entrenamiento centradas en el desarrollo de la capacidad aeróbica y anaeróbica por lo que la utilización de SD adecuados puede mejorar el rendimiento de estos deportistas.
Objetivo: Determinar la prevalencia de consumo de SD en remeros de élite universitarios y evaluar el grado de evidencia del SD consumido.
Método: Estudio descriptivo y transversal en el que han participado 14 remeros del equipo de remo de la Universidad de Alicante. Se utilizó un cuestionario, previamente validado, para recoger los datos pertinentes al consumo de SD.
Resultados: Los SD más consumidos fueron: cafeína (81%), proteína de suero (75%), creatina monohidrato (62,5%), barritas energéticas (56,3%), bebida isotónica (50%) y BCAA (43,7%). La finalidad principal de su uso fue para mejorar el rendimiento deportivo y solo un 33% estaba asesorado por un dietista-nutricionista.
Conclusión: La mayoría de los SD utilizados por los remeros tienen respaldo científico. Por lo que sería interesante que se llevasen a cabo más investigaciones en esta población.
RECONCILING LEARNING AND TEACHING STYLES IN SCIENCE, TECHNOLOGY ENGINEERING AND MATHEMATICS DISCIPLINES THROUGH COGENERATIVE DIALOGUES
Authors: Nunez Rodriguez Nelson
Published: September 2021

The use of cogenerative dialogues in Science disciplines is a pedagogical approach bringing together the plethora of academic and cultural backgrounds of current community college students. Specifically, this project illustrates the effects of integrating cogens in a community college chemistry class for science majors. Cogenerative dialogues were implemented in a Hostos Community College spring 2011 chemistry class as follows: some students discussed class issues with the professor in an informal setting once a week. An integrative assignment connecting typical foods from different countries was used as a framework to reinforce the learning process and to unravel content misunderstanding. The project outcomes transcended spring 2011 semester. A new book has been adopted in the class as a result of the dialogue. Oral presentations, the use of masteringchemistry.com and a forum to create exam questions have been implemented. Office hours are now used to both develop specific class problems and to dialogue with students about learning styles. Overall, cogenerative dialogues have opened a venue to facilitate the learning of difficult science concepts while building an atmosphere of acceptance, respect, and collegiality between instructor and the students.
Key words: cogenerative dialogues, student diversity, college STEM teaching and learning.
ORGANIZATIONAL DETERMINANTS OF TEACHER RESPONSIBILITY AND ENGAGEMENT AMONG ADULT EDUCATORS IN NORWAY
Authors: Turmo Are , Christophersen Knut-Andreas , Elstad Eyvind
Published: September 2021

The purpose of the current research was to use structural equation modeling to estimate the organizational determinants of teacher responsibility and engagement among adult educators in immigrant schools in Norway. The path coefficients were estimated using data from a sample of Norwegian adult educators. The empirical analysis showed clear relations among the components of the model. Relational trust and informal learning among adult educators were seen as important precursors of adult educator responsibility, but the contextual factors appeared to be more complex. The analysis showed that authorities in charge of immigrant schools should design policies that consider the trust and relationships among adult educators. Personal influences are important for adult educator responsibility. Although the study has several limitations (i.e., the cross-sectional nature of the study and the fact that self-reported data were used), it contributes new insights into the empirical foundation for the model.
Key words: adult education, informal learning, job autonomy, leadership, teacher responsibility.
