Student engagement in Higher Education, age and parental education level
Authors: COVAS Filomena , VEIGA Feliciano Henriques
Published: May 2021

Abstract Within the scope of socio-cognitive theories, student engagement in school has been studied as a multidimensional construct. A four-dimensional perspective was adopted, with the dimensions: affective, cognitive, behavioural and agentic. The objective, to analyse how the variables age and parental education relate to student engagement in school. The sample consisted of 715 Portuguese public Higher Education students from the Lisbon area. The data was collected through an online survey, which included the Student Engagement in School: a Four-Dimensional Scale – Higher Education Version. Data analysis not only revealed that students of age 26 or older scored considerably higher results in engagement than younger colleagues, but also highlighted significant differences of engagement in the affective, behavioural and agentic dimensions, depending on parental education. The results, while partially corroborating the revised literature, suggest future in-depth studies.

Published: May 2021

Abstract The aim of this study was to investigate possible factors that prevent adherence to the treatment of codependent family members of problem drug use individuals. A quasi-experimental study was carried out with 133 relatives of psychoactive substances users who called the Brazilian drug hotline (Ligue 132) between 2013 and 2015, from the five regions of Brazil. The following instruments were used: General service protocol; Family assistance protocol; Holyoake Codependency Index; Behavioral Adherence Scale; and Adherence Factor Questionnaire. Univariate analysis of data was performed for categorical variables and Chi-square test for comparison between variables, with p < 0.05. The sample showed a predominance of women (91.7%), especially mothers (82.7%). Among the investigated factors, alcohol as the substance involved in the problem showed a significant association with the non-adherence to treatment through teleintervention of family members.
OS VINGADORES: MOBILIZAÇÃO DOS DISCURSOS DA RELIGIÃO, DO MITO, DA TECNOLOGIA, DA HISTÓRIA
Authors: Barros Maria Emília de Rodat de Aguiar Barreto
Published: May 2021

Resumo Este artigo aborda uma pesquisa pós-doutoral, analisando-se discursivamente a filmografia Vingadores. Examinam-se oito sequências enunciativas referentes ao primeiro filme, atentando-se para enunciados concernentes à violência/paz; à verdade/inverdade, ao conhecimento/desconhecimento, fundamentados nas pesquisas arqueológica, genealógica (FOUCAULT). Conforme a primeira, focalizam-se dois conceitos basilares: discurso e enunciado, a partir dos quais são estudados o objeto, os campos de saber nele/por ele mobilizados (religião/mito/ufologia; tecnologia/armamentismo; história), averiguando-se os acontecimentos em seu entorno. Atinente à genealogia, reflete-se sobre as relações entre poder, produção de verdades homogeneizadoras, capazes de universalizar culturas, modos de vida. Duas perguntas norteiam a análise: qual o papel dos discursos veiculados nesse Universo Cinematográfico para a criação do imaginário dos sujeitos? Num gesto arqueológico, questiona-se a conexão entre a mídia e a história do presente. Constata-se que os Vingadores são considerados pessoas notáveis, rememorando o poder político-econômico, armamentista estadunidense, a possível engenhosidade de seus heróis.
A SUBJETIVIDADE NOS DISCURSOS DA LITERATURA DE AUTOAJUDA
Authors: Oliveira Geilson Fernandes de , Mendes Marcília Luzia Gomes da Costa
Published: May 2021

Resumo O presente artigo tem como objetivo refletir sobre a questão da subjetividade nos livros da literatura de autoajuda, de modo específico nas obras Treinando a emoção para ser feliz (2007a) e 12 semanas para mudar uma vida (2007b), ambas do escritor brasileiro Augusto Cury. Tomando como base a perspectiva teórica e metodológica da Análise do Discurso (AD) de orientação francesa, especialmente aquela desenvolvida na esteira dos estudos foucaultianos, são empreendidas discussões sobre a problemática. A partir de um processo de descrição e interpretação dos enunciados que compõem o corpus, identifica-se, nos discursos analisados, a mobilização de dispositivos e práticas da relação do sujeito consigo mesmo, os quais discursivizam e trabalham com a produção de subjetividades na contemporaneidade e inscrevem-se em um campo da produção editorial marcado por condições de possibilidades históricas e sociais dadas.
IMPOLIDEZ E IDENTIDADES EM UMA INTERAÇÃO ON-LINE NO FACEBOOK: UMA ABORDAGEM SOCIODISCURSIVA
Authors: Barreto Filho Ricardo Rios , Barros Kazue Saito Monteiro de
Published: May 2021

Resumo Os sites de redes sociais, como o Facebook, podem servir como um palco de disputas políticas e ideológicas onde interlocutores entram em conflito, gerando linguagem ofensiva e disputas identitárias. Este artigo objetiva apresentar contribuições que os estudos das identidades podem fornecer à análise da impolidez - uso da língua para causar ofensa - em interações on-line. Para tanto, propõe a análise qualitativa de cunho interpretativista de uma postagem e seus respectivos comentários, coletados no Facebook. Os resultados sugerem que o estudo combinado entre impolidez e identidades possibilita demonstrar que o processo de ofensa nessa plataforma on-line é normalmente inferencial, e depende de processos de identificação com a impolidez presentes nos textos.

Resumo Este artigo discute o sentido de tensão com base nos conceitos de compreensão e avaliação em Bakhtin e o Círculo, considerando que os sentidos se constroem no encontro de dois polos opostos, como uma faísca elétrica (VOLÓCHINOV, 2017). Perguntas de pesquisa: O que é tensão como reflexão teórica? Quais são os possíveis pontos de tensão, considerando compreensão e avaliação nos textos selecionados das obras de Bakhtin e o Círculo? Coletados os dados em artigos de periódico acadêmico especializado, em três obras é constatada a recorrência dos conceitos sob análise. As reflexões e definições teóricas apontam para dois centros de circulação de valores em embate. Quanto aos resultados obtidos, compreensão e avaliação, dois centros de valores, atuam como duplo um do outro na preparação de uma resposta ativa por parte de um locutor.
Educating in Times of Pandemic: Images as Micropolitics of Epistemic Disobedience to the Modern and Humanist Epistemologies of the Global North
Authors: Mizan Souzana , Ferraz Daniel de Mello
Published: May 2021

ABSTRACT In this article, we take the risk of reading the contemporary world based on images that have been published on social media during the pandemic crisis. By questioning the abyssal lines (SOUSA SANTOS, 2007) imbued and naturalized by the projects of Modernity and Humanism, the article discusses the ways in which nature invaded, in the middle of the pandemic, “this side” of modernity. The following section explores the undemocratic virus by problematizing the abyssal lines of social class differences. Then, in order to further complexify the stark differences between white supremacy and black genocide, the next section demonstrates that we have not overcome this historical crisis of humanity. Section five investigates the abyssal lines between access to education and the perpetuation of a project for education that secures the denial of its existence. In the conclusion, we explain the reasons that make us conceive of these images as procedural micropolitics that have the potential to construct “new modes of subjectivity” (GUATTARI; ROLNIK, 1996, p. 30) and suggest a pedagogy of visual literacy and its micropolitics and an epistemic turn in the notions of “crisis”.
Implicated Literacies: Life Begetting Life in Linguistic Education
Authors: Silva Simone Batista da
Published: May 2021

ABSTRACT We are almost 8 billion people to live, eat and survive on the only inhabitable planet, yet few of us care for environmental issues. Our relationship with the Nature, in general, has been one of exploitation and spoliation, following the anthropocentric modern narrative that prioritizes an egocentric mindset. The outcomes are deprivation, scarcity, depletion of natural organisms, destruction of the space as a whole. Anchored in decolonial and transdisciplinary studies, this text ponders on the consequences of the Eurocentric narratives, claims the need of collectively building a different narrative, and advocates in favor of implicated literacies, a pedagogy for language teaching that understands that “life on Earth implicates life”, and encourages the improvement of environmental and social relations in a broader conception of sustainability.

Problem-solving and coping in family adaptation of children with Down Syndrome
Authors: Braga Patrícia Pinto , Silva Juliana Barony da , Guimarães Bárbara Radieddine , Riper Márcia Van , Duarte Elysângela Dittz
Published: May 2021

ABSTRACT Objective: To analyze problem-solving and coping strategies of parents of children with Down Syndrome in family adaptation. Method: This is a qualitative research that used the Resiliency Model of Family Stress, Adjustment, and Adaptation. Participants were mothers and/or fathers from 40 families of children aged 1 to 7 years diagnosed with DS. Directed content analysis was performed, supported by software and considering a code dictionary. Results: Problem-solving and coping proved to be a set of actions, behaviors, efforts, and communications that contributed to family adaptation and favored balance between the demands imposed by Down Syndrome and the acquisition of resources by the family. Conclusion: In the first moment, which corresponds to the time of news or diagnosis of the syndrome and the first days after birth, internal and external resources, which represent coping, are developed to accept and refocus ideas and feelings towards Down Syndrome. Over time these resources have an effect and cause changes in family functioning patterns and in the relationship of these families with the outside world, as they seek child development.

Published: May 2021

ABSTRACT Objective: To evaluate the effectiveness of complementary therapies in the management of symptom clusters in children and adolescents with cancer undergoing palliative care. Method: Systematic review guided by the Preferred Reporting Items for Systematic Reviews and Meta-Analyses, resorting to the databases MEDLINE, Web of Science, Central Cochrane, and PsycINFO. The identification, selection, inclusion, extraction, and methodological assessment were conducted by two independent reviewers. Results: Five quasi-experiments met the eligibility criteria. The heterogeneous characteristics of the studies made meta-analysis impossible. Two studies used therapeutic massage, one used Reiki, one used boswellic acid, and one used Cannabis sativa; three of them (therapeutic massage and Reiki) presented statistically significant results for the management of the cluster pain-anxiety-worry-dyspnea. Most studies presented a moderate risk of bias as per ROBINS-I tool. Conclusion: Therapeutic massage and Reiki may be effective for the symptom clusters management, especially the pain-anxiety-worry-dyspnea cluster in children and adolescents undergoing palliative care.
Reliability and resilience of flood detention (storage) reservoirs
Authors: Mergen Stephanie , Courtnadge Andrew Peter , Torenga Elmar Kees , Brown Alan John
Published: May 2021

There are now around 200 large flood detention reservoirs (FDRs) in England, typically designed to attenuate floods and thus prevent flooding downstream for events with an annual exceedance probability up to 1 in 100, sometimes but not always with provision for climate change. There is some evidence that these structures do not always provide the intended standard of protection and this paper explores the available data and possible reasons for this. The paper concludes with some suggested simple sensitivity tests to examine the reliability and resilience of a FDR in attenuating floods, including the impact of climate change.
Partial clinker replacement by calcined clays for green cement production
Authors: Kavas Taner , Kurtuluş Recep , Kurtuluş Cansu
Published: May 2021

Recently, intensive attention has been paid to environmental concerns for securing a more sustainable future. In particular, numerous research studies have been directed toward emerging green materials for minimizing carbon dioxide footprint. In this work, the authors aimed to fabricate an environmentally friendly cement by implementing partial addition of calcined clays in place of clinker. The clay minerals labeled as yellow (YC) and green (GC) were initially calcined at different temperatures in separate processes. The mixed design step was then carried out by replacing with 3, 5 and 10 wt% calcined clay minerals in place of clinker to obtain ordinary Portland cement. Ten different samples (N1 to N10) were successfully prepared. The samples were subjected to some mineralogical, physical and mechanical analyses. The findings clearly showed that the addition of partially calcined clay minerals in substitution for clinker is a very effective method to obtain green cement. Further, the compressive strength measurements (after 28 days) revealed that the highest value (56.4 MPa), which is relatively greater than that of the undoped N10 (54.5 MPa), can be achieved with the incorporation of 10 wt% YC750. In conclusion, the authors report that the partial replacement of clinker by calcined clay can be an alternative green cement blend.
The Treasury Market Flash Event of February 25, 2021
Authors: Aronovich Alex , Dobrev Dobrislav , Meldrum Andrew
Published: May 2021

The Treasury market flash event of February 25, 2021 underscores the pivotal role of high-speed liquidity provision in the most liquid electronic parts of the Treasury market. We find evidence that the sharp drop in prices that day was accompanied by a sudden drop in market depth and a brief deterioration in high-speed liquidity provision amid elevated transaction volumes, albeit to a much lesser extent than during the episode of severe illiquidity in March 2020. Similar to some previous episodes accompanied by moderately elevated economic and financial market uncertainty, market depth has recovered steadily since February 25 at a pace comparable to that observed following other such episodes, while high-speed liquidity provision appears to have rebounded fairly quickly. That said, market depth has taken over a month to partially recover, which suggests that Treasury market liquidity has been more heavily reliant on high-speed replenishment to meet trading demand and may remain fragile.
Arbitrage Capital of Global Banks
Authors: Anderson Alyssa G. , Du Wenxin , Schlusche Bernd
Published: May 2021

We show that the role of unsecured, short-term wholesale funding for global banks has changed significantly in the post-financial-crisis regulatory environment. Global banks mainly use such funding to finance liquid, near risk-free arbitrage positions—in particular, the interest on excess reserves arbitrage and the covered interest rate parity arbitrage. In this environment, we examine the response of global banks to a large negative wholesale funding shock as a result of the U.S. money market mutual fund reform implemented in 2016. In contrast to past episodes of wholesale funding dry-ups, we find that the primary response of global banks to the reform was a cutback in arbitrage positions that relied on unsecured funding, rather than a reduction in loan provision.
The Global Determinants of International Equity Risk Premiums
Authors: Londono Juan M. , Xu Nancy R.
Published: May 2021

We examine the commonality in international equity risk premiums by linking empirical evidence for the international stock return predictability of US downside and upside variance risk premiums (DVP and UVP, respectively) with implications from an international asset pricing framework, which takes the perspective of a US/global investor and features asymmetric global macroeconomic, financial market, and risk aversion shocks. We find that DVP and UVP predict international stock returns through different global equity risk premium determinants: bad and good macroeconomic uncertainties, respectively. Across countries, US investors demand lower macroeconomic risk compensation but higher financial market risk compensation for more-integrated countries.
Panbiogeografía de los matorrales de la Región Xerofítica Mexicana
Authors: Morales-Garduño Luis , Solano Eloy , Villaseñor José Luis , Montaño-Arias Genaro
Published: May 2021

Antecedentes: Los matorrales xerófilos de México se han estudiado florística y ecológicamente, pero pocos estudios incluyen el método panbiogeográfico para describir los patrones de distribución de sus especies.
Hipótesis: La Región Xerofítica Mexicana contiene una riqueza alta de especies endémicas de México que se relacionan con el bioma matorral xerófilo, la mayoría son propias de esta región. Con base en estas especies se puede proponer una regionalización de las zonas áridas de México.
Área de estudio: Región Xerofítica Mexicana.
Resultados: Se identificaron 11 trazos generalizados ubicados en las provincias biogeográficas de Baja California, Sonora, Altiplano Norte, Altiplano Sur y Eje Volcánico. Se registraron 13 nodos biogeográficos, la mayoría ubicados en el Altiplano Sur. Las especies endémicas analizadas son características del matorral xerófilo, algunas de ellas se comparten con los bosques templados.
Conclusiones: Se reconocieron cinco zonas áridas de México: Desierto de Sonora, Valle de Tehuacán-Cuicatlán, Desierto Chihuahuense, zona árida Guanajuato-Jalisciense y zona árida Queretano-Hidalguense. Es probable que las últimas cuatro áreas constituyeran una zona árida continua, fragmentada por eventos geológicos y climáticos recientes. Los nodos registrados permitieron reconocer áreas con riqueza alta de endemismos que deben ser conservadas.
Physiological screening of ruderal weed biomonitors of atmospheric nitrogen deposition
Authors: Martínez D. Nayeli , De la Barrera Erick
Published: May 2021

Background: Plants take up various species of reactive nitrogen and their different physiological responses to the increase of nitrogen availability can be useful in biomonitoring.
Questions: Does atmospheric nitrogen deposition affect the physiology of ruderal weeds? Which species are most responsive to the nitrogen deposition?
Studied species: Eleven ruderal weeds.
Study site and dates: Morelia, Michoacán, Mexico. 2019.
Methods: Under scenarios of 10, 20, 40 and 80 kg N ha-1year-1, we quantified plant responses of biomass production, nitrate reductase activity, chlorophyll content, photosynthetic efficiency, δ15N, nitrogen and carbon content.
Results: Total biomass production increased with the rate of nitrogen deposition for Bidens pilosa , Chloris gayana, Lepidium virginicum , and Pennisetum setaceum, as chlorophyll content in B. pilosa , C. gayana , and L. virginicum. In turn, the below- to above-ground biomass ratio decreased for B. pilosa and C. gayana, as photosynthetic efficiency in C. gayana , L. virginicum , and Chloris pycnothrix . Nitrate reductase activity was only affected in L. virginicumm , C. gayana , and T. officinale.
   With the exception of C. pycnothrix , the nitrogen content increased, while the carbon augmented in C. gayana , C. pycnothrix, and P. setaceum . The C/N ratio was reduced in B. pilosa , C. gayana, Chloris virgata, P. setaceum, and T. officinale . The δ15N was increased in B. pilosa, C. gayana, C. virgata and P. setaceum .
Conclusions: Bidens pilosa, C. gayana, L. virginicum, and P. setaceum were the species with more affected variables to nitrogen deposition, which could be useful in the biomonitoring.

Examination and possible interpretations of a Middle Bronze Age structured deposition
Authors: Gucsi László , Szabó Nóra
Published: May 2021

Ceramic depositions occur frequently in the Bronze Age throughout the Carpathian Basin, however, their characteristics and composition can vary between periods, cultures and regions. Thus there could be many theories and interpretations offered for the reasons behind hiding these depots. At the site of Budajenő, Hegyiszántók a structured deposition dating to the final phase of the Middle Bronze Age came to light, which is not only unique in terms of the quantity of the vessels but also of their quality, both on an intra-site level and from the perspective of the Hungarian Middle Bronze Age. The aim of this paper is to present a complex and multi-faceted analysis, which helps not only to understand the possible reasons behind the concealment of the vessels, but also to offer an interpretation for the chain of events in which they could have played a central role. Besides the examination of the quantity and the cultural characteristics of the vessels, traces of use-wear,along with the phenomena of secondary burning and deliberate fragmentations are also discussed.

Methods of Identification for Ceramics with Traces of Secondary Burning and their Occurrences in Mortuary and Ritual-related Assemblages
Authors: Gucsi László
Published: May 2021

Among archaeological assemblages recovered both from settlement sites and burial grounds, the presence of ceramics with traces of secondary burning is a relatively common phenomenon. The identification of such traces can nuance the interpretation of the archaeological contexts within which these ceramics occur. In case of cremation burials, it can highlight the details of the cremation process. However, most publications seem to mention secondarily burnt ceramics either when the pieces are clearly severely burnt, deformed or blistered, despite these cases being only partial representations of the whole phenomenon. Based on previous experience, three levels of secondary burning can be distinguished on archaeological ceramics: slight, moderate and severe secondary burning. This more detailed classification could aid the reconstruction of funerary rituals. The recognition and the correct identification of such ceramic pieces can provide details on whether a certain vessel (or vessel types) was/were placed on the funeral pyre or was only tangentially involved in the cremation process.
Újdonságok – kellékek – rítus – interpretáció - Novelties – Accessories – Rituals – Interpretation

Published: May 2021

Az új típusú tárgyak megjelenése nem csak bővülő kapcsolatrendszert, státusz- és presztízsjavak cseréjét és/vagy új etnikum megjelenését jelezheti, hanem ezek a korábban ismeretlen tárgyak egyben egy másik gondolkodásmód, eszmerendszer zárt és gyakran szigorúan következetes módon előkerülő kellékei, rítust jelző és bizonyító felszerelések. A regölyi tumulus építménye sem a korábban a Kárpát-medencében feltárt halomszerkezetet mutatja. A boronafalú építményt vesszővel font cölöpsor övezi, melyet kívülről faszénrétegre alapozott, vastag, keményre döngölt agyagköpeny borít. Az építmény belsejében 9×6 oszlop tartotta a lapos tetőt. A padlóba mélyedő gödrök alját kővel rakták ki, és mint arra az iráni párhuzamok is utalnak, a föld szentsége miatt erre helyezhették a halottaikat, majd a bomlási folyamat után a maradványokat megsemmisítették. Emberi csontokat nem találtunk, csak nagy mennyiségű, erősen fragmentált, részben szintén idegen eredetű, új típusú leletanyagot. Közülük kiemelkedő fontosságúak a bronzedények töredékei (bogrács, situla, cista). A cista új típusként jelenik meg ekkor, és a többi bordázott bronzvödör vizsgálatával legalább két műhelyt sikerült elkülönítenünk. A bronzedényeket a sörfogyasztás megjelenésével kapcsoljuk össze, ezeket a készleteket változatos kivitelű és finomságú kerámia- és üveg phiálékkal tették teljessé. Szintén az újdonságok közé tartozik a füstölőlánc használata; más típusainak öntőmintáit korábban ugyancsak Regölyben találták .Ezeket a tárgyakat – funkciójukban – az ókori Kelet palotareliefjein láthatjuk. Szintén novum a fedőperemes edények használata, ami a teázás megjelenésére utal. A temetkezés rítusa a Mazda-hit szokásait idézi, ahhoz köthető a tűzoltárokat szimbolizáló füstölők használata is. Mindezek egy konkrét eseménnyel értelmezhetők, melynek során a Kr. e. 7. század utolsó negyedében a kimmer szövetséghez tartozók (szigünnák és más sztyeppei kapcsolatokkal is rendelkező néptöredékek) több hullámban menekültek Európába, – magukkal hozva mestereket, ismereteket, rituális hagyományokat –, és megalapozták Európa vaskori átalakulását.

Hogyan deríthetők fel régészeti módszerekkel rituális cselekvések nyomai? Esszénk első részében a rituálé fogalmi meghatározásának nehézségeivel foglalkozunk. Amellett érvelünk, hogy alapvetően a kutató által kialakított kategóriáról van szó, ezért a „rituális cselekvés” azonosításának a régészeti emlékanyagban nincs egységes, minden esetben alkalmazható kritériumrendszere. A „cselekvés” fizikai lenyomatai azonban vizsgálhatók egységes szempontok szerint. Ilyen egységes elemző módszer lehet a műveletsor, ami az anyagi kultúra előállításának, használatának és eldobásának technikáin keresztül hatol az egykori közösség kulturális értékeinek szövetébe. A „rítus” az elemzést követően, a rekonstruált cselekvésmódok összességének értelmezésekor válik megvilágító erejű fogalommá. Esettanulmányunk, a boldogkőváraljai pengedepó segítségével mutatjuk be, hogyan kapcsoljuk össze a műveletsor analitikai eszközeit a rituális cselekvés értelmezési tartományával.
Evaluation of elasticity of the pancreas by Acoustic Radiation Force Impulse (ARFI) in acute pancreatitis patients: A systematic review and meta-analysis (protocol) v2
Authors: Rifu Kazuma , Watanabe Jun , Sasanuma Hideki , Taniguchi Nobuyuki
Published: May 2021

Acute pancreatitis (AP) is characterized by inflammation of the pancreas(1). The morbidity of AP is reported about 5-80/100000 people/year (2). An increase in the incidence of AP has been also reported (3-9). The mortality rate has been reported to be 1.7-8.4% (10, 11), and AP still remains a life-threatening disease. Clinical symptoms and elevated levels of pancreatic enzymes constitute the main diagnostic features of this condition.(12, 13) Early diagnosis and treatment are important, and reliable imaging techniques are required for a diagnosis of acute pancreatitis. Acoustic radiation force impulse (ARFI) elastography is a promising ultrasound-based imaging modality for the evaluation of tissue stiffness including in the diagnosis of AP (14). Studies using the ARFI elastography evaluated different abdominal organs(15), especially in pancreatic disease, such as AP, chronic pancreatitis, or pancreatic carcinoma, relevant higher shear wave velocities than in healthy pancreas parenchyma are described(1, 16, 17). In this study, we evaluated acoustic radiation force impulse (ARFI) elastography, Virtual Touch tissue quantification (VTQ; Siemens Medical Solutions, Mountain View, CA),to diagnose acute pancreatitis. The consistency of the pancreatic parenchyma usually becomes stiffer in acute pancreatitis as compared to the healthy pancreas, which is identifiable with Share Wave Elastography (SWE), including ARFI (18, 19). However, studies using elastographic techniques in patients with acute pancreatitis are conflicting(19).One prospective study failed to find significant differences in pancreatic shear wave velocities between patients with AP and healthy volunteers(14, 19). Three other studies showed significantly higher pancreatic shear wave velocities in patients with acute pancreatitis compared to persons with the normal pancreas(1, 18-20). The present study will aim to assess the effectiveness of ARFI elastography in the form of ARFI-VTQ imaging in characterizing and differentiating normal pancreas and acute pancreatitis.

Bu çalışmanın amacı fen bilimleri öğretmen adaylarının Tahmin Et- Gözle- Açıkla (TGA) yöntemine dayalı deney tasarımı konusundaki yeterliliklerinin belirlenmesidir. Bu amaç doğrultusunda çalışmada nitel araştırma yöntemlerinden biri olan bütüncül tek durum deseninden yararlanılmıştır. Araştırma 2018-2019 eğitim öğretim yılında İstanbul’da bir üniversitede Fen Öğretimi Laboratuvar Uygulamaları-2 dersini almakta olan 57 fen bilimleri öğretmen adayının katılımı ile gerçekleştirilmiştir. Çalışma kapsamında öğretmen adaylarına TGA yöntemi ile ilgili dört saatlik seminer dersi verilmiştir. Seminerden üç hafta sonra öğretmen adayları gruplar oluşturarak mayalanma konusunda TGA yöntemine dayalı bir deney tasarlayarak bu tasarımı rapor haline getirmişlerdir. Bunun sonucunda 17 adet rapor veri kaynağı olarak elde edilmiştir. Çalışmada veri toplama aracı olarak TGA’ya dayalı deney tasarımlarını değerlendirmek amacıyla araştırmacılar tarafından alan yazın taraması sonucunda geliştirilen 11 maddelik TGA tasarımı değerlendirme aracı (TGAT) kullanılmıştır. TGA’ya dayalı deney tasarımları tahmin, gözlem, açıklama aşamalarındaki ifadeler bakımından kapalı kodlama yoluyla betimsel olarak iki bağımsız değerlendirici tarafından analiz edilmiş ve verilerin güvenirliği için hesaplanan uyuşum yüzdesinin .86 olduğu belirlenmiştir. Araştırma sonucunda öğretmen adaylarının deney tasarlarken gözlem aşamasında yeterli (%72), tahmin aşamasında kısmen yeterli (%45) ve açıklama aşamasında yetersiz (%20,5) oldukları görülmektedir. TGA’ya dayalı deney tasarımlarının tüm aşamaları değerlendirildiğinde ise başarı yüzdesinin %49,5 olduğu ve bu değerin ortalama değere yakın olduğu ve adayların tasarımlarında kısmen yeterli oldukları belirlenmiştir.

Mathematical modeling of errors for determining time of death based on the Newton’s–Richman’s cooling law
Authors: Nedugov German V.
Published: May 2021

Background: A mandatory factor in the development and implementation of diagnostic technologies for determining the time of death by the thermal method is the assessment of possible errors. For equations of cadaver cooling that have a deterministic character, error estimation is possible using a mathematical model of indirect measurement. Here, a mathematical model has been proposed for estimating the maximum absolute error in determining death on the basis of the Newton'sRichman's cooling law under conditions of constant and changing ambient temperature. Aim: Using a mathematical model of indirect measurement, this study developed a method for estimating errors in determining the prescription of death according to the Newton'sRichman's cooling law. Material and methods: Mathematical modeling of errors in determining the time of death in conditions of constant and changing ambient temperature was conducted according to the Newton'sRichman's law. The computer program code was drafted in the C# programming language using the Microsoft Visual Studio 2019 application. Results: Based on the indirect measurement model, a method for estimating the maximum absolute errors for determining the time of death during cooling according to the Newton'sRichman's law under conditions of constant and changing ambient temperature was developed. The results obtained allowed us to analytically determine errors in time the prescription of death in the early postmortem period. Conclusions: We developed a mathematical model for estimating maximum absolute errors while determining the time of death according to the Newton'sRichman's cooling law under conditions of constant and changing ambient temperature. The developed mathematical model was implemented as an application program Warm Bodies NRN. The proposed method might be used in forensic medical expert practice for determining the time of death.

The 2017 Mw 6.5 Jiuzhaigou mainshock hit the northeastern end of the Bayan Har block, which has experienced many historical earthquakes, including the 1976 M 7.2 Songpan-Pingwu earthquake swarm. We used the double-difference tomography method to perform a joint inversion of the seismic source and P-wave velocity (VP) structure of the Jiuzhaigou-Songpan-Pingwu region. The results show significant lateral heterogeneity in the VP in the mid-upper crust. The velocity structure in the shallow crust correlates well with the surface geology. The Jiuzhaigou mainshock and Songpan-Pingwu earthquake swarm both occurred at the boundary between high- and low-VP anomalies. The Songpan-Pingwu earthquake swarm may be related to the eastward flow of low-viscosity material in the mid-lower crust of the Tibetan plateau. Low-viscosity material intrudes into the bedrock when it encounters the rigid Motianling massif, resulting in surface uplift and thrust earthquakes. By contrast, the Jiuzhaigou earthquake is associated with strain energy accumulating at the boundary between high- and low-VP anomalies related to the different movement rates of the low-VP material in the mid-lower crust and the high-VP body in the mid-upper crust. In this case, the high-VP body ruptures with a strike-slip sense to the southeast.
Relations between MaxRotD50 and Some Horizontal Components of Ground-Motion Intensity Used in Practice
Authors: Poulos Alan , Miranda Eduardo
Published: May 2021

The most commonly used intensity measure of ground motion in earthquake engineering is the 5% damped spectral ordinate, which varies in different directions. Several different measures have been proposed over the years to combine the intensity of the two horizontal recorded ground motions to derive ground-motion models as well as for design purposes. This study provides the relation to seven previously used measures of horizontal ground motion with respect to a recently proposed orientation-independent measure of horizontal ground-motion intensity referred to as MaxRotD50. This new measure of horizontal intensity is defined as the median value of the maximum spectral ordinate of two orthogonal directions computed for all possible nonredundant orientations. The relations are computed using 5065 pairs of horizontal ground motions taken from the database of ground motions recorded in shallow crustal earthquakes in active tectonic regions developed as part of the Pacific Earthquake Engineering Research Center’s Next Generation Attenuation-West2 project. Empirically derived period-dependent relations are presented for three quantities that permit transforming any of the seven other definitions of horizontal ground-motion intensity to MaxRotD50, namely, (1) geometric mean of the ratio of MaxRotD50 to any of the seven other measures of intensities, (2) standard deviation of the natural logarithm of the ratio of MaxRotD50 to any of the seven other measures of intensities, and (3) the correlation between the natural logarithm of the ratio of MaxRotD50 to the other measures of intensities and the natural logarithm of the other measure of intensity. In addition, the influence of site class at the recording station, earthquake magnitude, and distance to the horizontal projection of the rupture is examined on the geometric mean of the ratio of MaxRotD50 to the median intensity of all nonredundant orientations (i.e., RotD50), showing negligible influence of site class and only a relatively small influence of magnitude and distance.
Rupture Passing Probabilities at Fault Bends and Steps, with Application to Rupture Length Probabilities for Earthquake Early Warning
Authors: Biasi Glenn P. , Wesnousky Steven G.
Published: May 2021

Earthquake early warning (EEW) systems can quickly identify the beginning of a significant earthquake rupture, but the first seconds of seismic data have not been found to predict the final rupture length. We present two approaches for estimating probabilities of rupture length given the rupture initiation from an EEW system. In the first approach, bends and steps on the fault are interpreted as physical mechanisms for rupture arrest. Arrest probability relations are developed from empirical observations and depend on bend angle and step size. Probability of arrest compounds serially with increasing rupture length as bends or steps are encountered. In the second approach, time-independent rates among ruptures from the Uniform California Earthquake Rupture Forecast, Version 3 (UCERF3), are interpreted to apply to the time-dependent condition in which rupture grows from a known starting point. Length probabilities from a Gutenberg–Richter magnitude–frequency relation provide a reference of comparison. We illustrate the new approach using the discretized fault model for California developed for UCERF3. For the case of rupture initiating on the southeast end of the San Andreas fault we find the geometric complexity of the Mill Creek section impedes most ruptures, and only ∼5% are predicted to reach to San Bernardino on the eastern edge of the greater Los Angeles region. Conditional probabilities of length can be precompiled in this manner for any initiation point on the fault system and thus are of potential value in seismic hazard and EEW applications.
