R function for extracting F-test P-value from linear model object
Authors: Turner Stephen
Published: December 2024

I thought it would be trivial to extract the p-value on the F-test of a linear regression model (testing the null hypothesis R²=0). If I fit the linear model: fit<-lm(y~x1+x2), I can't seem to find it in names(fit) or summary(fit). But summary(fit)$fstatistic does give you the F statistic, and both degrees of freedom, so I wrote this function to quickly pull out the p-value from this F-test on a lm object, and added it to my R profile.

Epistasis in New Places
Authors:   Unknown
Published: December 2024

Coming from the lineage of Jason Moore, I am obliged to occasionally remind everyone that biological systems are inherently complex, and to some degree, we should therefore expect statistical models involving those systems to be complex as well. With the development of GWAS, many approaches to examine epistasis are weighed down by the computational burden of exhaustively conducting billions of statistical tests.
Seminar: T-Test on Fold Changes
Authors: Turner Stephen
Published: December 2024

I've had friends in biochem "wet" labs who've asked me to do some simple statistics on some of their results. This looks like an interesting seminar to attend if you've ever thought about doing a t-test on fold changes in some outcome measure between treatment and control groups, a pretty common outcome in biochemical assays. If the speaker provides slides electronically I'll happily post them here after the seminar.

Designing streets for people: A multicriteria decision-making study
Authors: Fernando Kowalski , Masiero Érico , Manuel Saraiva , Dos Santos , Simões Gomes , Stanujkić Dragiša
Published: December 2024

Designing Streets for People involves selecting appropriate materials, determining the optimal configuration, and finding the best solution based on technical criteria for urban structures. This paper aims to identify the best solution by comparing two multicriteria decision-making methods: the WISP (Weighted Sum-Product) and AHP-Gaussian, which represents a recent algorithm for the Analytical Hierarchy Process (AHP) decisionmaking. We created a matrix with eight factors (cost, braking distance, lifetime, sidewalk width, carbon footprint, electricity consumption, and pavement temperature) to choose between four pavement options (concrete and asphalt with different sidewalk widths). The WISP recommended a concrete pavement and 2.0-meter sidewalk. The least viable option was asphalt pavement with a 1.2-meter sidewalk, due to its higher carbon footprint (12%), increased air temperatures (10%), and greater public lighting expenses (11%). WISP allows for assigning weights to criteria with robustness, computational effectiveness, and transparency. Conversely, AHP-Gaussian incorporates a sensitivity feature that lets decision-makers assign weights based on statistical analysis. Despite each method's limitations, both are suitable for urban projects, estimating decisions based on multiple technical aspects, thereby promoting more integrated and efficient choices.

Discursive strategies of motivational speech: A positive discourse analysis of Jay Shetty’s video
Authors: Abdul-ajid Aliya B.
Published: December 2024

Motivational speech has emerged as a significant trend in social media, driven by the increasing demand for personal development content and the accessibility of digital platforms. With the rise of platforms such as YouTube, Instagram, and TikTok, motivational speakers now can reach global audiences instantaneously. This shift has transformed motivational speaking from a niche practice into a widespread cultural phenomenon. Now, this paper was positioned to analyze the presence of discursive strategies—linguistic and rhetorical techniques to convey meanings—within motivational speech videos. Positive discourse analysis was carried out to analyze a viral motivational video from Jay Shetty identifying prevalent discursive strategies. Findings indicated that Jay Shetty perspectivation/framing/discourse representation (39.7%), argumentation (20.7%), referential/nomination (15.5%), predication (13.8%), and intensification/mitigation (10.3%) in his viral video. He used linguistic and rhetorical techniques, like metaphors and analogies, to craft his messages in a way that resonates deeply with his audience, making them relatable and impactful. Through selected words, persuasive structures, and storytelling, he engages listeners emotionally and intellectually, guiding them toward self-reflection and personal growth. His use of rhetorical questions encourages introspection, prompting viewers to think critically about their own lives and decisions. By framing his narratives in ways that connect personal challenges to universal experiences, Shetty had a sense of shared understanding, making his audience feel seen and motivated to take action. Consequently, motivational speech on social media has evolved into a powerful tool for shaping public discourse, promoting mental health, develop resilience, and inspiring positive life changes across societies and culture.
Utilizaçao de técnicas de interferometria holográfica na detecçao de defeitos em compósitos laminados

Published: December 2024

No presente trabalho utilizam-se as técnicas de interferometria holográfica para a detecção de defei tos em placas laminadas de carbono/epóxido. Foram analisadas placas com 16 camadas e duas orientações de fibras, sendo uma simétrica, [0,90,0,90]2s e outra antissimétrica [0,90]8. Impactos de baixa velocidade e energia foram utilizados para gerar defeitos no interior das placas. A presença dos defeitos é revelada por alterações no campo de deslocamentos à superfície. Esta informação foi obtida por ESPI (Electronic Speckle Pattern Interferometry) e por Shearography. Para a análise dos resultados recorreu-se a algoritmos de processamento de imagem. Verificou-se que as placas com empilhamento antissimétrico oferecem uma maior resistência ao impacto do que as placas com empilhamento simétrico.
Learning Ecology at the Eco- Park
Authors: Bautista Mary Josephine
Published: December 2024

This study aimed to determine the learning outcomes that the students in Ecology achieved at the Eco-Park at West Visayas State University Lambunao Campus, Lambunao, Iloilo. The participants of the study were the BEED IV-B students taking Bio 217 (Ecology) during the frst semester of the school year 2009 – 2010. The students divided themselves into four groups. Each group conducted ecology-related activities such as construction of herbal garden and nursery for fruit bearing trees, waste management, and biodiversity assessment. Performances of students were self – rated and validated by their group leaders and the subject teacher. Teacher’s basis for the grades/score included pre and post-tests, interviews, transcripts of focus – group discussions, feld notes, journals of rejections, photo elicitations of workplace and activities of students, checklist, and informal visits. Learning was in the real world where students appreciated the relevance of the scientific method to the environment. The said environment was different from the controlled, school science laboratory room. Students became fascinated with nature, and they had the opportunity to explore the plants and animals in their environments. Outdoor education at an Eco- Park enhanced the students’ learning of ecology.
Uloga
pedagoga u osnovnim i srednjim školama za vrijeme pandemije bolesti COVID-19
Authors: Marinović Fani
Published: December 2024

Specifični uvjeti života i rada u 2020. godini suočili su pedagoge s novim zahtjevima zbog čega je naglasak u ovom radu postavljen na utvrđivanje njihove uloge u osnovnim i srednjim školama za vrijeme pandemije bolesti COVID-19. Provedeno je kvalitativno istraživanje na uzorku od deset stručnih suradnika pedagoga zaposlenih u osnovnim i srednjim školama diljem Republike Hrvatske. Rezultati istraživanja pokazali su kako je uloga pedagoga tijekom pandemije bila prvenstveno organizacijska i koordinacijska, a važnu ulogu pedagozi su imali u pružanju emocionalne podrške, ali i motiviranju učenika i nastavnika. Drugačiji oblik provedbe nastave zahtijevao je usvajanje novih načina komunikacije u čemu je svakodnevna suradnja pedagoga s ostalim sudionicima odgojno-obrazovnog procesa bila ključna za uspješnu provedbu nastave.

Published: December 2024

Darovitim učenicima potrebna je sustavna odgojno-obrazovna podrška kako bi imali priliku ostvariti svoje potencijale. Cilj ovog istraživanja je analizirati trenutno stanje rada s darovitim učenicima u osnovnim školama tri hrvatske županije: Splitsko-dalmatinskoj, Osječko-baranjskoj i Virovitičko-podravskoj. Anketni upitnik, konstruiran za potrebe istraživanja, je proveden na ukupno 483 učitelja razredne nastave u 171 osnovnoj školi. Ispitani su načini identifikacije darovitih učenika, pružanje podrške istima, interes učitelja za edukacije u području darovitosti te su provjerene razlike na navedenim varijablama između županija. Dobiveni rezultati upućuju na to kako se u većini škola najčešće provodi subjektivna procjena kao način identifikacije, a podrška se najčešće pruža u kontekstu dodatne nastave i natjecanja. Učitelji također iskazuju visoki interes za edukacije i daljnji razvoj u području darovitosti.

Repo Intermediation and Central Clearing: An Analysis of Sponsored Repo
Authors: Copeland Adam , Kahn R. Jay
Published: December 2024

This paper evaluates the salient forces behind a dealer-intermediary’s decision to move a bilateral repo transaction with a customer into central clearing. We provide evidence that dealers turn to sponsored repo on occasions when balance sheet space is scarce, such as when there is a large issuance of Treasury coupon securities and end-of-month dates. We also find that sponsored repo spreads tend to be affected by a range of factors, with the three largest drivers being money market fund assets, a proxy for hedge fund demand for repo funding, and end-of-month dates.
Minimum required sample size for modelling daily cyclic patterns in ecological momentary assessment data
Authors: van de Maat Robin , Lataster Johan , Verboon Peter
Published: December 2024

Cyclical patterns in ecological momentary assessment (EMA) data on emotions have remained relatively underresearched. Addressing such patterns can help to better understand emotion dynamics across time and contexts. However, no general rules of thumb are readily available for psychological researchers to determine the required sample size for measuring cyclical patterns in emotions. This study, therefore, estimates the minimum required sample sizes—in terms of the number of measurements per time period and subjects—to obtain a power of 80% given a certain underlying cyclical pattern based on input parameter values derived from an empirical EMA dataset. Estimated minimum required sample sizes varied between 50 subjects and 10 measurements per subject for accurately detecting cyclical patterns with a large magnitude, to 60 subjects and 30 measurements per subject for cyclical patterns of small magnitude. The resulting rules of thumb for sample sizes are discussed with a number of considerations in mind.
Informative hypothesis testing in the EffectLiteR framework: A tutorial
Authors: Keck Caroline , Mayer Axel , Rosseel Yves
Published: December 2024

In this paper, we illustrate how the typical workflow in analyzing psychological data, including analysis of variance and null hypothesis significance testing, may fail to bridge the gap between research questions and statistical procedures. It fails, because it does not provide us with the quantities of interest, which are often average and conditional effects, and it is insufficient, because it does not take the expectations of the researcher about these quantities into account. Using a running example, we demonstrate that the EffectLiteR framework as well as informative hypothesis testing are more suitable to narrow the gap between research questions and statistical procedures. Furthermore, we provide two empirical data examples, one in the context of linear regression and one in the context of the generalized linear model, to further illustrate the use of informative hypothesis testing in the EffectLiteR framework.
Desafio do Ensino da Unidade temática Esportes na Educação Física Escolar no contexto do Currículo Base do Território Catarinense
Authors: Laureano Henrique de Souza , Bendrath Eduard Angelo
Published: December 2024

O Estado de Santa Catarina, após a promulgação da Base Nacional Comum Curricular, elaborou o Currículo Base do Território Catarinense (CBTC), finalizado em 2019, e implantado nas escolas públicas estaduais e municipais das cidades que aderiram a esse documento. As reflexões expressas neste estudo buscam investigar como ocorreu a implantação da Unidade Temática Esportes do CBTC nas escolas da rede municipal e estadual de uma cidade do interior do estado. A pesquisa toma como referência os documentos curriculares orientadores, faz uma abordagem da Educação Física nos documentos curriculares de Santa Catarina e traz apontamentos sobre o ensino dos esportes na escola. Para obtenção dos dados, foi realizada entrevista semiestruturada com os professores de Educação Física do Ensino Fundamental – Anos Finais das escolas das redes estadual e municipal de uma cidade de pequeno porte do estado. A entrevista abordou a prática pedagógica dos professores, a implantação do currículo, a formação continuada e a organização do planejamento com base nos documentos curriculares orientadores. A pesquisa apontou uma defasagem no processo de formação continuada dos professores. Bem como identificou uma centralização no ensino dos esportes tradicionais como vôlei e futebol, mesmo com o CBTC propondo um ensino diversificado de modalidades esportivas. Essa centralização está relacionada aos espaços e materiais disponíveis na escola e aos aspectos da cultura local, que influenciam a organização dos planejamentos de ensino dos professores.
Knowledge and Emotions in Socioscientific Decision Making
Authors: Lacorte Jed Henry
Published: December 2024

Socioscientific issues require practical decisions that use knowledge and emotions as inputs for the decision-making process. To examine how these resources influence decision-making, this investigation was conducted from a constructionist epistemological stance, a symbolic interactionism theoretical perspective, and a grounded theory methodology. Twenty-five informants were purposefully selected based on the study’s selection criteria. Data were collected through semi-structured interviews, transcribed, and analyzed using Hennink and Kaiser’s strategies to achieve theoretical saturation. The analysis revealed that: (1) Knowledge of socioscientific issues was associated with emotion-related objects that elicited negative emotional responses from decision-makers; (2) These negative emotions triggered the use of related conceptual and contextual knowledge in generating decision alternatives; (3) Positive emotions motivated decision alternatives toward specific goals; (4) Decision alternatives contained both cognitive and affective components; and (5) Decisions were based on the appraisal of the overall cognitive and affective baggage of these alternatives. The findings underscored the importance of decision-makers enhancing their cognitive and affective resources and incorporating both when making practical decisions to effectively ad-dress socioscientific issues, thereby contributing to positive outcomes for individuals, societies, and the global community.
CONVERGÊNCIAS ENTRE AS COMPETÊNCIAS DA REDAÇÃO DO ENEM E O CICLO DE ENSINO E APRENDIZAGEM
Authors: ALVES AGOSTINHO DE SA CICERA
Published: December 2024

As competências avaliadas na redação do Exame Nacional do Ensino Médio (ENEM) são exploradas com frequência em aulas de Língua Portuguesa no Ensino Médio, voltadas à produção textual, já que seu resultado equivale à nota de uma área no referido exame. Apesar do amplo investimento nesse trabalho, as médias alcançadas por candidatos egressos da rede pública na área não equivalem a 600 pontos.  Considerando as contribuições do Ciclo de Ensino e Aprendizagem para o trabalho com a produção de textos, este estudo objetiva analisar os pontos de convergências entre as estratégias que integram os ciclos do CEA e as competências avaliadas no ENEM. O método explorado neste estudo é qualitativo, visto que será realizada uma abordagem comparativa entre as proposições do CEA e as competências avaliadas na redação do ENEM. Os resultados apontam que as estratégias que integram o CEA são contempladas nas competências avaliadas na redação do ENEM, embora a organização das competências não possibilite identificar em que medida a organização sequencial das estratégias do CEA se realiza. Este estudo é importante por utilizar-se da orientação teórico-metodológica do CEA para a abordagem de texto do domínio da exposição e exposição, a exemplo da redação cobrada no ENEM.

Text neck syndrome (TNS) is prevalent among mobile users, and exercise is a simple, non-invasive approach, for treating chronic neck pain. Research on Thai yoga (TY) exercise to relieve or reduce neck and shoulder pain in people with TNS is still limited. This study aimed to investigate the effects of TY exercise on health, physical function and quality of life in patients with TNS. A randomized clinical trial was conducted from April to July 2023 (TCTR20230920002, 10/2023). Seventy-eight volunteers with TNS participated in the study, performing TY exercises, while continuing their routine daily life (CON) for 6 weeks, with week 8 as a follow-up appointment. Clinical evaluation was conducted using a numerical pain-rating scale, functional disability scored by the neck disability index questionnaire (NDI), range of motion (ROM) and cervical vertebral angle, rounded shoulder angle by goniometry, and health-related quality of life (QoL) assessed by the 36-Item Short Form Survey. The results of the numerical pain-rating scale for TY group in the follow-up (6.71±0.52 weeks) were significantly different (p-value < 0.001) from the baseline (4.18±0.95) while the CON group showed no change. The NDI also decreased from the baseline (5.03±1.38) in the TY group, while the CON group remained at 12.03±1.98. The data of craniovertebral angle of TY group show an increase from baseline (62.44±2.32) while CON group was 39.37±4.73. The results showed that the rounded shoulder angle of TY group decreased to the normal range. The TY group shows an increased degree from baseline. The results for the TY group demonstrated a significant increase in QoL. These findings suggest that TY exercise is effective for relieving TNS when compared with the CON group. These positive outcomes provide strong support for the use of TY as an effective intervention for treating TNS symptoms.

The quality assurance of education plays a critical role in realizing the long-term vision of schools aimed at improving educational quality and preparing students for future challenges. Schools face the challenge of ensuring that all educational processes, from planning to evaluation, align with the established standards and support the school's vision. This study explores how educational quality assurance can contribute to achieving school visions by reviewing existing literature. Using a qualitative approach and literature review methodology, this research analyzes various sources, including academic journals, books, and government regulations related to quality assurance and school management. The analysis focuses on key components of quality assurance, such as setting educational standards, effective school management, continuous teacher professional development, and active stakeholder participation. These components are critical in aligning short-term goals with long-term visions, ensuring consistent improvement in educational outcomes. The study also addresses challenges schools face in implementing quality assurance, such as limited resources, resistance to change, and the lack of understanding and consistent application of quality standards across different schools. The findings suggest that overcoming these challenges requires collaborative efforts from the government, schools, teachers, students, and parents. Effective leadership, robust monitoring, and flexible policies are essential for successful implementation. Ultimately, quality assurance can serve as an effective tool for driving continuous improvement in schools and ensuring that the school's vision is realized through high-quality education.
