APFELSTRUDEL, 80 CAMADAS DA MAIS FINA MASSA FOLHEADA DE MÚLTIPLOS EUS: UMA HOMENAGEM A CLAUDIO WILLER
Authors: Dantas Marta , Silva Vanessa Tavares da
Published: August 2021

O presente ensaio é uma homenagem ao poeta, ensaísta e tradutor paulistano Claudio Willer que, em dezembro de 2020, completou 80 anos. Por meio de um diálogo entre seus textos em prosa, alguns poemas e sua fortuna crítica, far-se-á um exame de sua trajetória, iniciada em meados da década de 1960. De matriz surrealista, sua atuação se dá, sobretudo, numa atitude que entrelaça sua produção com um modo de vida que, por sua vez, se desdobra nessa produção. O poeta absorve, em sua prática, uma concepção da literatura livre do cerceamento da razão e aberto à contemplação do caráter enigmático e mágico do universo. Nessa perspectiva, traduziu obras de autores importantes para os fundamentos do Surrealismo e da literatura beat. Partindo das considerações de Leila Perrone-Moisés, é possível compreender as múltiplas atuações de Willer, seu jogo profuso de Eus, poeta, tradutor e crítico teórico, com os mais diversos interlocutores, como componentes de um escopo necessário à vitalidade dos pressupostos surrealistas na atividade artística e literária do país. O entrecruzamento de suas ações sinaliza também a própria tessitura da intertextualidade de sua poesia, seu recurso mais radical. Afinal, antiaristotélico pelo avesso, a palavra poética é, para Willer, agente mágico que produz realidade.

"A CHRISTMAS MEMORY" AND THE NARRATIVE OF EMOTION
Authors: Oliven Rafael Campos
Published: August 2021

Este artigo tem por objetivo analisar importantes aspectos narratológicos na construção de "A Christmas Memory", de Truman Capote. O objetivo principal é demonstrar como a emoção é um elemento chave na formação e desenvolvimento dos dois personagens principais do conto e examinar os temas e motivos que o subjazem. Como referência teórica, os artigos de H. Porter Abbott "Story, plot and narration" e "Introduction" de David Herman são utilizados, ambos do Cambridge Companion to Narrative, entre outros, assim como teorias contemporâneas sobre narrativa, personagem e focalização. A linguagem ela mesma é examinada como um meio de transmitir diferentes matizes de emoção e sentimentos.
OS SENTIDOS DA PALAVRA FAMÍLIA A PARTIR DE ABORDAGENS ACERCA DE UNIÃO ESTÁVEL
Authors: Teixeira Byron de Castro Muniz , Ventura Adilson
Published: August 2021

Este artigo tem como objetivo analisar o sentido da palavra família em enunciados do livro Direito de Família, de Pablo Stolze Gagliano e Rodolfo Pamplona Filho, entendido como um livro doutrinário que visa fazer o estudioso do Direito interpretar a Lei e entender seu funcionamento na sociedade. Selecionamos, como corpus para análise, três recortes que indicam o entendimento da Doutrina acerca da União Estável e a possível interpretação dos Juristas. Nossa análise se dará no campo teórico da Semântica do Acontecimento, observando como se dá as relações no espaço da enunciação, que é um espaço político, constituído pelos locutores e pela língua. A Semântica do Acontecimento conceitua a enunciação como uma prática política, que instala o conflito no centro do dizer, e para quem a constituição dos sentidos é histórica e a relação do sujeito com a língua ocorre no acontecimento. Como suporte metodológico, serão observados os sentidos e as relações dos termos em textos extraídos do livro Direito de Família, a partir das relações nas enunciações. Para tanto, utilizaremos os procedimentos de reescrituração, articulação e Domínio Semântico de Determinação (D.S.D.). Ademais utilizaremos paráfrases que servirão de sustentação para as possíveis conclusões. Percebe-se que os enunciados analisados apontam para lugares em que se percebe um embate de sentidos, que coloca de um lado a lei, a qual impõe um casamento formal, com caráter heterossexual, enquanto a união estável, também denominada no recorte, como união de fato, é constituída “à margem” da lei, sendo desprovida de solenidades e inferior ao casamento.

Reproductive colonization of land by frogs: embryos and larvae excrete urea to avoid ammonia toxicity
Authors: Narvaez Javier Mendez , Warkentin Karen
Published: August 2021

Vertebrate colonization of land occurred multiple times, including over
50 origins of terrestrial eggs in frogs. Some environmental factors and
phenotypic responses that facilitated these transitions are known, but
responses to water constraints and risk of ammonia toxicity during early
development are poorly understood. We tested if ammonia accumulation and
dehydration risk induce a shift from ammonia to urea excretion during in
early stages of four anurans, from three origins of terrestrial
development. We quantified ammonia and urea concentrations during early
development on land, under well-hydrated and dry conditions. Where we
found urea excretion, we tested for a plastic increase under dry
conditions and with ammonia accumulation in developmental environments.
We assessed the potential adaptive role of urea excretion by comparing
ammonia tolerance measured in 96h-LC50 tests with ammonia levels in
developmental environments. Ammonia accumulated in foam nests and
perivitelline fluid, increasing over development and reaching higher
concentrations under dry conditions. All four species showed high
ammonia tolerance, compared to fishes and aquatic-breeding frogs. Both
nest-dwelling larvae of Leptodactylus fragilis and late embryos of
Hyalinobatrachium fleischmanni excreted urea, showing a plastic increase
under dry conditions. These two species can develop the longest on land
and urea excretion appears adaptive, preventing their exposure to
potentially lethal levels of ammonia. Neither late embryos of Agalychnis
callidryas nor nest-dwelling larvae of Engystomops pustulosus risked
toxic ammonia levels under dry conditions, and neither excreted urea.
Our results suggests that an early onset of urea excretion, its increase
under dry conditions, and elevated ammonia tolerance, can all help
prevent ammonia toxicity during terrestrial development. High ammonia
represents a general risk for development that can be exacerbated as
climate change increases dehydration risk for terrestrial-breeding
frogs. It may also be a cue that elicits adaptive physiological
responses during early development.
Estimating the burden of adult hospital admissions due to RSV and other respiratory pathogens in England
Authors: Sharp Ashley , Minaji Mehdi , Panagiotopoulos Nikolaos , Reeves Rachel , Charlett Andre , Pebody Richard
Published: August 2021

Respiratory Syncytial Virus (RSV) is a common seasonal respiratory virus
and an important cause of illness among infants, but the burden of RSV
disease is not well described among the older population. The objective
of this study was to estimate the age-specific incidence of hospital
admission among over 65s due to respiratory illnesses attributable to
RSV in England to inform optimal vaccine and therapeutic interventions.
We used linear multiple regression to examine the effect of changes in
weekly counts of respiratory pathogens on the weekly counts of
respiratory hospital admissions. The study population was all patients
aged 65 years or over admitted to English hospitals between 2nd August
2010 and 30th July 2017. RSV was estimated to account for a seasonal
annual average of 71 (95% CI 52-90) respiratory admissions per 100,000
in adults age 65-74 and 251 (95% CI 186-316) admissions per 100,000
adults age 75+. Pneumococcus was the pathogen responsible for highest
annual average respiratory admission with 448 (95% CI 310-587)
admissions per 100,000 adults age 65-74 and 1010 (95%CI 527-1493)
admissions per 100,000 adults aged 75+. This study shows that RSV
continues to exert a significant burden of disease among older adults in
England. These findings will support development of policy for the use
of RSV therapeutics and vaccines in this age group.

Progression of Aortic Stenosis in Patients with Bicuspid Aortic Valve
Authors: Shang Michael , Kahler-Quesada Arianna , Mori Makoto , Yousef Sameh , Geirsson Arnar , Vallabhajosyula Prashanth
Published: August 2021

Background: Bicuspid aortic valve is the most common congenital heart
defect and predisposes patients to developing aortic stenosis more
frequently and at a younger age than the general population. However,
the influence of bicuspid aortic valve on the rate of progression of
aortic stenosis remains unclear. Methods: In 236 patients (177 tricuspid
aortic valve, 59 bicuspid aortic valve) matched by initial severity of
mild or moderate aortic stenosis, we retrospectively analyzed baseline
echocardiogram at diagnosis with latest available follow-up
echocardiogram. Baseline comorbidities, annualized progression rate of
hemodynamic parameters, and hazard of aortic valve replacement were
compared between valve phenotypes. Results: Median echocardiographic
follow-up was 2.6 (IQR 1.6-4.2) years. Patients with tricuspid aortic
stenosis were significantly older with more frequent comorbid
hypertension and congestive heart failure. Median annualized progression
rate of mean gradient was 2.3 (IQR 0.6-5.0) mmHg/year vs. 1.5 (IQR
0.5-4.1) mmHg/year (p=0.5), and that of peak velocity was 0.14 (IQR
0-0.31) m/s/year vs. 0.10 (IQR 0.04-0.26) m/s/year (p=0.7) for tricuspid
vs. bicuspid aortic valve, respectively. On multivariate analyses,
bicuspid aortic valve was not significantly associated with more rapid
progression of aortic stenosis. In a stepwise Cox proportional hazards
model adjusted for baseline mean gradient, bicuspid aortic valve was
associated with increased hazard of aortic valve replacement (HR: 1.7,
95% CI [1.0, 3.0], p=0.049). Conclusion: Bicuspid aortic valve may
not significantly predispose patients to more rapid progression of mild
or moderate aortic stenosis. Guidelines for echocardiographic
surveillance of aortic stenosis need not be influenced by valve
phenotype.
Continuous synthesis of TiO2-supported noble metal NPs and their application in ammonia borane hydrolysis
Authors: Luo Lamei , Yang Mei , Chen Guangwen
Published: August 2021

A stabilizer-free method based on segmented flow for the continuous
synthesis of TiO2 supported noble metal nanoparticles (M/TiO2-MR, M =
Pd, Pt or Au) was proposed. Due to the enhanced mixing performance
arising from the internal convection in the discrete plugs, the particle
size of noble metal nanoparticles could be well controlled by reducing
the metal precursors with NaBH4 just in the presence of TiO2 without
using any stabilizer. In comparison with the batch method, the
as-prepared M/TiO2-MR had smaller noble metal particle size and better
dispersity. Experimental results showed that adjusting the oil-to-water
phase ratio or increasing the total volume flow rate and synthetic
temperature could lead to smaller average particle size with narrower
distribution. The as-prepared M/TiO2-MR possessed higher catalytic
activities in the hydrolysis of ammonia borane than those prepared by
the batch method, which could be ascribed to smaller noble metal
nanoparticles, exposing more active sites.

Students’ argumentation ability is necessary for education today, which emphasizes the student-centered learning process. One way to see students’ argumentation ability is by having a discussion. Therefore, this study aimed to describe the Toulmin argumentation process for students during focus group discussions (FGD). This research is qualitative. The data collection instrument used was an open-ended questionnaire assisted by Google Form that contained common problems of the distance learning process during a pandemic. The subjects of this study consisted of fifty students from the University of Mataram. The results showed that the argumentation process was divided into three categories. The first category was the one-sentence argument. There were 58 %, or 29 students, who belonged in this category. The second category was the two sentences argument. There are 30 %, or 15 students belonged in this category. Lastly, 12 % or six students belonged to the more than three sentence argument category. The results of this study indicated that many students could not provide complete arguments. Thus, the role of lecturers is significant to improve students’ ability in providing complete argumentations. Therefore, the researchers suggest that lecturers should apply learning models that invite students to argue and discuss.

Nicel yöntemin anket tekniği ile veriler toplanmıştır. Yeniliklerin kurum personeli nezdinde ne ölçüde etki ettiğini, bu etkinin kamu personelinin örgütsel sinizm davranışlarına yansımalarını ortaya koymak adına geliştirilen “yenilik algısı ölçeği” ile çalışmaya uyarlanan “örgütsel sinizm ölçeği” Sosyal Güvenlik Kurumu (SGK) kamu personeline yüz yüze uygulanmıştır. Bu araştırmada ölçüm yapmak üzere e-Devlet uygulamalarının oluşturduğu yenilik algısı tercih edilmiştir. SGK’nın seçilme sebebi ise e-Devlet uygulamaları içinde en çok kullanılan uygulamanın SGK uygulamalarından 4A Hizmet dökümü uygulamasının olmasıdır. Örgütsel sinizm en basit tanımıyla çalışanların değişime karşı ve kuruma karşı kalıplaşan alaycı, tepkili, olumsuz tutumlarıdır. Örgütlerde yaşanan bu köklü dönüşümlerin örgütsel sinizm olgusuna da etkisinin olacağı öngörülmüştür. Toplanan veriler bu öngörüyü desteklemiş, çalışanların yenilik algısının örgütsel sinizm üzerinde anlamlı bir etkiye sahip olduğu ortaya koyulmuştur. Ayrıca bu değişkenlerin demografik verilere bağlı farklılıkları da sorgulanmıştır. Kadın ve erkeklerin yenilik algılarının ve örgütsel sinizm düzeylerinin anlamlı farklılık gösterdiği, yaş, mesleki kıdem ve eğitim durumuna göre söz konusu değişkenlerin anlamlı farklılıklar gösterdiği sonuçlarına ulaşılmıştır. Ayrıca bölgesel karşılaştırmada yenilik algısının farklılık göstermediği ama örgütsel sinizm düzeyinin anlamlı farklılıklar arz ettiği sonucuna ulaşılmıştır.

Ülkelerin hem araştırmacı işgücü olarak hem de akademik işgücü olarak doktora mezunlarına ihtiyaçları bulunmaktadır. Bu nedenle doktora yapanların sayısının artması önem taşımaktadır. Akademik personel olmadan doktora eğitimine devam eden kişilerle ilgili araştırmaların azlığı dikkat çekmektedir. Çalışmada akademisyen olmadan dışarıdan doktora yapan kişilerin motivasyonları, deneyimleri ve yaşadıkları sorunlar fenomenolojik bir desende nitel bir araştırma ile incelenmiştir. Ege Bölgesinde bulunan iki devlet üniversitesinde doktora eğitimi gören 23 kişiden oluşan örneklemin çoğunluğu akademik kariyerde bulunmak istemektedir. Sosyalleşme konusunda ise kısmen kendilerini alanın parçası hissetmektedir. Son olarak kadroda olmamaktan kaynaklanan ekonomik sorunlar yaşadıkları belirlenmiştir.
Enflasyon ve İşçi Transferleri arasındaki Nedensellik İlişkisi: Türkiye Örneği
Authors: ARI Ayşe
Published: August 2021

Bu çalışmanın amacı işçi transferleri ve enflasyon arasındaki ilişkiyi Türkiye için ortaya koymaktır. Bu amaçla 1987-2019 dönemi ele alınmış ve Johansen yaklaşımı, FMOLS yöntemi ve Hacker-Hatemi (2006) nedensellik testi kullanılmıştır. Johansen testi sonucuna göre, değişkenler arasında uzun dönem ilişki bulunmaktadır. FMOLS analizi bulguları ise, teoride beklenildiği gibi işçi transferlerinin enflasyonu artırdığını göstermektedir. Ayrıca, dış borçların enflasyon üzerinde pozitif etkiye sahip olduğu ancak dışa açıklık oranının istatistiksel olarak anlamlı olmadığı tespit edilmiştir. Hacker-Hatemi (2006) testi sonucu ise, işçi transferlerinden enflasyona doğru tek yönlü bir nedenselliğin varlığını göstermektedir.

Takibe düşmüş krediler/toplam krediler oranı ve toplam rezervler/toplam dış borç değişkeni ile anlamlı ve pozitif bir ilişki bulunmuştur.
Reflections on Post-Conference Feedback as a Developmental Teacher Training Strategy: Teaching Practice Supervisors’ Experiences in an ODL Institution
Authors: Makgakga Tshegofatso , Ngubane-Mokiwa Sindile
Published: August 2021

Nationally and internationally, higher education institutions offer teaching practice as one of the teacher training support strategies to develop pre-service teachers’ pedagogical knowledge and skills. The University of South Africa is one of the higher education institutions that offer open and distance learning and has a high number of pre-service teachers. The University’s teaching practice is supervised by experts and culminates in a conferencing session in which the supervisor provides feedback on various aspects of the teaching practice. This study explored the teaching practice supervisors’ reflections on post-conference feedback as a developmental approach towards reinforcing assessment for learning. The qualitative approach was used as the researchers interpreted these supervisors’ reflections on post-conference feedback as a developmental approach. Through purposive sampling, supervisors who had supervised pre-service teachers for three or more years were selected. The findings of this study showed that post-conference feedback was developmental to pre-service teachers and supervisors. The findings further illuminated the way in which supervisors had assessed pre-service teachers’ teaching skills to understand their strengths and weaknesses. In addition, the study identified pitfalls such as time and the supervisor-to-pre-service-teacher ratio as 1:10 per week, which was unsustainable. The study suggests that there is a need to set clear and specific outcomes for assessment, to provide a self-assessment rubric for pre-service teachers to avoid conflicts during the post-conference feedback, and to arrange professional development workshops to be conducted with the supervisors.
Diferentes análises estatísticas podem levar a conclusões categoricamente distintas
Authors: Lima Jr Ronaldo Mangueira , Garcia Guilherme Duarte
Published: August 2021

Neste estudo, demonstramos como significância estatística pode variar a partir da comparação de quatro métodos distintos: teste t, ANOVA (seguida de Tukey HSD), modelo linear simples, e modelo linear de efeitos mistos. Em nossa demonstração, modelamos tempos de reação em função de diferentes afixos em dinamarquês, e mostramos como nossas conclusões a respeito do efeito de certos afixos podem mudar categoricamente dependendo de qual dos métodos mencionados acima decidimos utilizar. Por fim, reiteramos o que dizem estudos recentes (e.g., BARR et al., 2013), e sugerimos que modelos de efeitos mistos devam ser a norma sempre que dados agrupados forem analisados. Esperamos, com este estudo, alertar pesquisadores da área para a importância de decisões analíticas bem informadas e éticas em estudos linguísticos.

Objetivo: Esclarecer a eficácia do Implante Valvar Aórtico Transcateter (TAVI) no tratamento da estenose valvar aórtica revisando suas evidências clínicas, comparando com o tratamento cirúrgico convencional e evidenciando suas limitações, complicações e custo efetividade a partir da análise da produção científica atual sobre o tema. Revisão bibliográfica: A Estenose Aórtica (EA) é uma doença comum do sistema cardiovascular e que pode levar à deterioração progressiva do ventrículo esquerdo. Em muitos casos, a intervenção cirúrgica é necessária a fim de garantir a sobrevida do paciente. Dentre as técnicas disponíveis, o TAVI, quando comparado à cirurgia convencional, garante áreas valvares maiores e com melhores desempenhos hemodinâmicos, reduz o tempo cirúrgico e de recuperação pós-operatória e, ainda, mostrou-se superior em relação à ocorrência de algumas complicações. Dessa forma, o TAVI é tido como técnica padrão-ouro para pacientes de alto risco e uma opção para médio e baixo risco. Considerações finais: O TAVI apresenta benefícios no tratamento da EA, principalmente em pacientes graves onde a cirurgia convencional é contraindicada. Entretanto, o custo, a falta de conhecimento médico sobre a técnica e de estrutura hospitalar adequada podem ser fatores limitantes no nosso país.
A randomized controlled pilot study of a proprietary combination versus sunscreen in melasma maintenance
Authors: Chatterjee Manas , Neema Shekhar , Rajput Gopalsing Rameshsing
Published: August 2021

Background:

Melasma is the commonest cause of facial hypermelanosis in skin type IV-VI. First-line treatment includes a triple combination containing topical corticosteroid and hydroquinone which have side effects on prolonged use. Chemical peels are a second-line management option with the laser being used in refractory cases, but the worsening of hyperpigmentation in darker skin types can occur following laser therapy. Sunscreen is a must to prevent relapses.

Aims and Objectives:

(i) To compare the effects of treatment with a proprietary combination (phenyl ethyl resorcinol, nonapeptide-1, aminoethyl phosphinic acid, antioxidants and sunscreen) versus sunscreen alone in limiting or reducing, melasma and preventing recurrence as a maintenance regimen after the initial use of triple combination,(ii) to evaluate the safety of the formulation studied, and (iii) to study the improvement of the quality of life of the patients after using the study formulation versus placebo.

Methods:

It was a prospective double-blinded parallel-group randomized controlled pilot study. A total of 46 subjects were recruited by consecutive sampling methods and randomized to 23 each in case and control groups. The study period was eight months with three phases. Phase 1 constituted the application of triple combination for eight weeks by both groups followed by phase 2 with the case group applying proprietary medicine and the control group applying sunscreen. Phase 3 was a follow-up period to see the sustenance of results in both groups as well as any evidence of relapses. Sunscreen was applied in all three phases.

Results:

Case group in the study showed improvement in the melasma severity score and mean melanin index as measured by mexameter but it did not attain statistical significance as compared to the control group. The melasma area and severity index score showed a consistent reduction in the case group, whereas it increased in the control group from baseline.

Limitations:

Small sample size and a short follow-up period of our study were major limitations.

Conclusion:

The proprietary combination, which has sunscreen as one of its constituents, is more effective in maintaining remission after triple combination without any added inconvenience of application of two separate preparations as compared to sunscreen alone.
Apical reference point - A clinical perspective

Published: August 2021

The clinicians face various challenges in trying to find the optimum working length during root canal treatment. Unless proper biomechanical preparation up to the apical limit is done, reinfection of the canal occurs. Apical reference point must be measured with at most care as to avoid any damage to the surrounding periodontal tissues during the treatment.
