French Religious Music
Authors: Vézina Caroline
Published: May 2023

From the early days of the colony, African Americans were exposed to the music of the Catholic Church. By 1754, the Ursuline owned a manuscript of spiritual or moral songs, Nouvelles Poésies Spirituelles et Morales, sung in French at a time when many characteristics of French vocal technique, such as the Notes Inégales, were very similar to African American music. Founded in the 1830s by three Free Women of Color Les Soeur de la Sainte-Famille—The Sisters of the Holy Family—also used music as an important part of their educational and evangelizing efforts. Singing cantiques both at church and at home, Creole Catholics eventually appropriated them by preserving only the most dramatic elements of the lyrics which they performed with a syncopated but flowing rhythm, making them the French counterpart of the Negro Spirituals, along which they stand as one of the precursors of jazz.
Reading Baldwin’s “Sonny Blues” while Listening to The Band
Authors: Pence Charlotte
Published: May 2023

Charlotte Pence’s “Reading Baldwin’s ‘Sonny Blues’ while Listening to The Band” assesses The Band in light of James Baldwin’s famous story—with focus on “different strategies for the ‘I’ in poetry, nonfiction, and fiction.” The chapter examines the differences in persona when used in fiction versus music and explores the literary history of the persona.
Chasing the Music
Authors: Scholes Jeffrey
Published: May 2023

Jeffrey Scholes’s “Chasing the Music: The Sacred and Profane in The Band’s Early Years” looks at The Band’s relationship with religion and religious themes, the sacred and the profane. The chapter suggests Music from Big Pink and The Band are the two most religious albums from the group, both possessing “a sacred quality for The Band.” Scholes draws from Emile Durkheim’s concept of the sacred and the profane, along with ideas from other religious scholars, as he explores the initial sacredness and eventual profundity of the group in their final years.
Literacy, the Woman’s Era, and the Literary Imagination
Authors: Cooper Anna Julia , Matthews Victoria Earle
Published: May 2023

This chapter outlines a brief history of the purposes of literacy instruction in the mid-nineteenth century. Additionally, this chapter describes the uses of literacy for Black people. Some Black public intellectuals and creative writers believed the persuasive power of the word could provide them the means to dismantle racial oppression and to affirm the humanity of Black people. With ferocity and intellectual acumen in 1892 and 1895 respectively, Anna J. Cooper and Victoria E. Matthews use their literacy skills to make bold pronouncements in two philosophical declarations on the purposes of race literature. Both declarations provide a roadmap for types of creative, cultural, and educational advancements that could reconfigure black lives. The literary imagination is tasked with taking on this charge. This chapter demonstrates how Cooper and Matthews’s philosophical declarations posit a kind of transformational literacy practice as a discursive and practical method for real change.
Authenticating Whiteness
Authors: Dubrofsky Rachel E.
Published: May 2023

Authenticating Whiteness details how popular media implicitly portrays whiteness as credible, dependable, trustworthy, familiar, and honest, and how this is normalized and ubiquitous. White people are constructed as believable. From the way they talk, to how they look, to their actions, white people in popular media are the ones to trust. The work details how ideas about what is natural and good are reified in media, by showing how such values are implicitly racialized.
Authenticating Whiteness is about how being seen as authentic has become evidence of authenticity. It is about understanding why assessing someone’s seeming authenticity is more important than what someone does, or the impact of their actions. It is about why we value people who seem to tell us the truth and show their real, inner selves, even if what they do and say is offensive, violent, or troubling. It is about why white people are forgiven their racist actions because these are articulated as not indicative of their inner authentic core.
The objects of analysis span a range of popular media—newspaper articles about Trump, a selfie at Auschwitz, videos by Miley Cyrus and Taylor Swift, the television series UnREAL, the cell phone video of Central Park Karen, the documentary Miss Americana—pinpointing patterns that cut across media to explore the cultural significance. At its heart, the book asks: Who gets to be authentic? What are the implications?
Authentic Monstrosity
Authors: Dubrofsky Rachel E.
Published: May 2023

This chapter explores how authenticity functions as a strategy of whiteness, arguing that it is Trump’s ability to appear monstrous and therefore authentic, coupled with his whiteness and his masculinity, that made him electable. Examining mainstream press about Trump during the primaries, the work asks: would we have Trump as president were it not for reality TV? What can reality TV offer to help us understand this Trump moment? The chapter uses the idea of inferential surveillance to pinpoint some of the ways reality TV ushered in key aspects of how we understand authenticity. The chapter argues that Trump’s success could only be achieved by a white man, enabling him to flout all requirements for appropriate behavior for a president, showing the dangerous alliance between whiteness and authenticity. The chapter forces an understanding of the Trump administration as part of a larger cultural ethos, and as a plausible outcome, rather than an anomaly.
Authentic Redemption
Authors: Dubrofsky Rachel E.
Published: May 2023

The focus of the chapter is mainstream articles about Breanna Mitchell, a white American teenage girl who took a smiling selfie at the Auschwitz Concentration Camp and posted it on her public Twitter account with the line “Selfie in the Auschwitz Concentration Camp” accompanied by a blushing smiling emoticon. Predictably, a month after Mitchell posted the selfie, it sparked public outrage and went viral. Paradoxically, in the news stories about Mitchell, she is at first condemned as narcissistic for her display of happy emotion at Auschwitz, but then presented as sympathetic for her exhibition of authentic feeling for her father who had passed away a year earlier. This chapter begins a discussion that continues in the next chapters about how agency for white women, and the display of appropriate authentic emotion, are in tension: the less agency white middle-class women exhibit, the more authentic they appear.
Authentic Whiteness
Authors: Dubrofsky Rachel E.
Published: May 2023

This chapter examines two popular music videos—one by Miley Cyrus, the other by Taylor Swift—to explore how expressing one’s authentic desires is a privilege most easily accessed by white bodies, fore fronting whiteness as a necessary aspect of free expression. Picking up arguments about gender and agency in previous chapters, this section examines how Cyrus and Swift are presented as authentic specifically because they have no control—no agency—over their desires, which emerge unwittingly and irrepressibly. Building on arguments about self-reflexivity as a way of marking that a person is not what they perform, developed in previous chapters, this chapter shows how self-reflexivity about performing racialized otherness can be used to shore up an irrepressible authentic inner white core that is separate and distinct from the racialized other that is performed.
La hermenéutica bíblica hobbesiana en el «Leviatán»
Authors: García-Alonso Marta
Published: May 2023

En este artículo vamos a analizar la redefinición a la que Hobbes somete en el Leviatán a los elementos esenciales de la hermenéutica bíblica protestante. Según el filósofo inglés definir las reglas que sirven para elaborar una exégesis adecuada, así como fijar el contenido que resulta de ello, es tarea del soberano, único intérprete autorizado de la Biblia. En base a estas ideas. Hobbes promueve la fundamentación de una nueva relación entre el poder civil y eclesial que le introduce como uno de los filósofos principales del debate teológico-político del siglo XVII.

Objectives

Markhamia lutea (M. lutea, Bignoniaceae) is mainly found in tropical/neotropical regions of America, Africa and Asia. The plant’s leaves, stems or roots are used to treat anaemia, bloody diarrhoea, parasitic and microbial infections. This study evaluates anti-inflammatory properties (in vitro) of Markhamia lutea and their curative effects on paclitaxel-induced intestinal toxicity (in vivo).

Methods

The anti-inflammatory potential of Markhamia lutea was tested over cytokines (TNF-alpha, IL-6, IL-1β, IL-10), reactive oxygen species (ROS) and enzymes (cyclooxygenase and 5-lipoxygenase). While in vivo, intestinal toxicity was induced for 10 days by oral administration of paclitaxel (3 mg/kg, 0.05 mL). Animals in each group were further treated with aqueous (300 mg/kg) and ethanolic (300 mg/kg) leaves extracts of Markhamia lutea during 7 days and clinical symptoms were recorded, hematological, biochemical and histological analysis were subsequently performed.

Results

In vitro, aqueous (250 μg/mL) and ethanolic (250 μg/mL) extracts of Markhamia lutea inhibited the activities of cyclooxygenase 1 (56.67 % and 69.38 %), cyclooxygenase 2 (50.67 % and 62.81 %) and 5-lipoxygenase (77.33 % and 86.00 %). These extracts inhibited the production of intracellular ROS, extracellular ROS and cell proliferation with maximum IC50 of 30.83 μg/mL, 38.67 μg/mL and 19.05 μg/mL respectively for the aqueous extract, then 25.46 μg/mL, 27.64 μg/mL and 7.34 μg/mL respectively for the ethanolic extract. The extracts also inhibited the production of proinflammatory cytokines (TNFα, IL-1β and IL-6) and stimulated the production of anti-inflammatory cytokines (IL-10). In vivo, after administration of paclitaxel, the aqueous and ethanolic extracts of Markhamia lutea significantly reduced the weight loss, the diarrheal stools and the mass/length intestines ratio of the treated animals compared to the animals of the negative control group. Biochemically, the extracts lead to a significant drop in serum creatinine and alanine aminotransferase levels, followed by a significant increase in alkaline phosphatase. In addition to bringing the haematological parameters back to normal values after disturbance by paclitaxel, the extracts caused tissue regeneration in the treated animals.

Conclusions

In vitro, aqueous and ethanolic extracts of Markhamia lutea showed anti-inflammatory properties (inhibition of COX1, COX2, 5-LOX activities, inhibition of ROS production and cell proliferation); in vivo, the same extracts showed curative properties against intestinal toxicity caused by paclitaxel.
A call for public funding of invasive and non-invasive prenatal testing
Authors: Maya Idit , Sukenik-Halevy Rivka , Basel-Salmon Lina , Sagi-Dain Lena
Published: May 2023

For decades, prenatal screening and genetic testing strategies were limited, requiring less complex decisions. Recently, however, several new advanced technologies were introduced, including chromosomal microarray analysis (CMA) and non-invasive prenatal screening (NIPS), bringing about the need to choose the most appropriate testing for each pregnancy. A worrisome issue is that opposed to the wide implementation and debates over public funding of NIPS, currently invasive testing is still recommended only in selected pregnancies with increased risk for chromosomal aberrations (according to screening tests or sonographic anomalies). This current decision-making regarding public funding for invasive and screening testing might compromise informed consent and patient’s autonomy. In this manuscript, we compare several characteristics of CMA vs. NIPS, namely: the accuracy and the diagnostic scope, the risks for miscarriage and for clinically uncertain findings, the timing for testing, and pretest counselling. We argue that it must be recognized that one size might not fit all, and suggest that both options should be presented to all couples through early genetic counseling, with public funding for the specific selected test.
Replicating physical motion with Minkowskian isorefractive spacetime crystals
Authors: Prudêncio Filipa R. , Silveirinha Mário G.
Published: May 2023

Here, we show that isorefractive spacetime crystals with a travelling-wave modulation may mimic rigorously the response of moving material systems. Unlike generic spacetime crystals, which are characterized by a bi-anisotropic coupling in the co-moving frame, isorefractive crystals exhibit an observer-independent response, resulting in isotropic constitutive relations devoid of any bianisotropy. We show how to take advantage of this property in the calculation of the band diagrams of isorefractive spacetime crystals in the laboratory frame and in the study of the synthetic Fresnel drag. Furthermore, we discuss the impact of considering either a Galilean or a Lorentz transformation in the homogenization of spacetime crystals, showing that the effective response is independent of the considered transformation.
Structural properties of alumina surfaces and their roles in the synthesis of environmentally persistent free radicals (EPFRs)
Authors: Altarawneh Mohammednoor , Assaf Niveen W. , Hussain Hamed M. , Dlugogorski Bogdan Z.
Published: May 2023

Alumina oxides have been widely utilised as independent catalysts or as support materials for other catalysts. From an environmental perspective, alumina nanoclusters dispersed on surfaces of particulate matter PM12, generated from various combustion processes, play a critical role in the synthesis of environmentally persistent free radicals (EPFRs). Of particular importance are phenoxy-type EPFRs that often act as building blocks for the formation of notorious pollutants. Herein, we present a systematic review of the literature pertinent to structural features of alumina surfaces at the nano-scale and their well-established role in the synthesis of EPFRs. Central to the capacity of alumina surfaces in mediating the formation of EPFRs are their active Lewis acid–base sites. The nature of these sites is very sensitive to hydration scenarios. As evident in electroparamagnetic resonance measurements, more than one category of EPFR forms on alumina surfaces. This generally entails the co-existence of various surface terminations, varying degrees of hydrations, and distinct underlying reaction pathways. The mechanisms for the formation of EPFRs over alumina surfaces involve interactions with terminal OH groups followed by creating genuine chemical bonds with Al3+ sites. Higher concentrations of EPFRs were often detected on alumina surfaces, in reference to other transition metal oxides. We envisage that future studies may focus on the generation of EPFRs from potential precursors other than phenols and catechol, such as brominated species and substituted thiophenols.

Tight regulation of Toll‐like receptor (TLR)‐mediated inflammatory responses is important for innate immunity. Here, we show that T‐cell death‐associated gene 51 (TDAG51/PHLDA1) is a novel regulator of the transcription factor FoxO1, regulating inflammatory mediator production in the lipopolysaccharide (LPS)‐induced inflammatory response. TDAG51 induction by LPS stimulation was mediated by the TLR2/4 signaling pathway in bone marrow‐derived macrophages (BMMs). LPS‐induced inflammatory mediator production was significantly decreased in TDAG51‐deficient BMMs. In TDAG51‐deficient mice, LPS‐ or pathogenic Escherichia coli infection‐induced lethal shock was reduced by decreasing serum proinflammatory cytokine levels. The recruitment of 14‐3‐3ζ to FoxO1 was competitively inhibited by the TDAG51‐FoxO1 interaction, leading to blockade of FoxO1 cytoplasmic translocation and thereby strengthening FoxO1 nuclear accumulation. TDAG51/FoxO1 double‐deficient BMMs showed significantly reduced inflammatory mediator production compared with TDAG51‐ or FoxO1‐deficient BMMs. TDAG51/FoxO1 double deficiency protected mice against LPS‐ or pathogenic E. coli infection‐induced lethal shock by weakening the systemic inflammatory response. Thus, these results indicate that TDAG51 acts as a regulator of the transcription factor FoxO1, leading to strengthened FoxO1 activity in the LPS‐induced inflammatory response.

Published: May 2023

OBJECTIVES

To inform clinical decisions on the use of probiotics in a pediatric inpatient setting, we sought to determine the number of cases of Lactobacillus bacteremia as well as associated patient characteristics in a tertiary-care pediatric hospital over an 11-year period.

METHODS

Cases of Lactobacillus bacteremia among admitted patients were identified through positive blood culture reports. The clinical chart for each case was reviewed for presenting symptoms and risk factors such as probiotic use, presence of a central venous catheter, immunocompromised state, impaired intestinal function, and age below 3 months. Concurrent total inpatient probiotic administration was assessed.

RESULTS

Over an 11-year period, 8 cases of Lactobacillus bacteremia were identified among 127 845 hospital admissions. All cases were associated with systemic signs of infection. Lactobacillus bacteremia patients most frequently had underlying impaired intestinal function and a central venous catheter. Three cases had a history of probiotic use. The peak number of annual cases did not coincide with the peak number of inpatients who received probiotics.

CONCLUSIONS

Lactobacillus bacteremia is uncommon and did not correlate with doses of probiotics-administered in the hospital. However, certain populations may be at higher risk and require extra consideration in clinical decision-making regarding use of probiotics.

Determination of chlorophyll and carotenoid content is an important way of obtaining information about the plant's photosynthetic activity as well as an indirect method of assessing the productivity of plant crops, particularly grain crops. The objective of this study was to evaluate the role of chlorophyll and carotenoid in the productivity formation of emmer wheat (Triticum dicoccum (Schrank.) Schuebl) grown under the traditional and organic farming systems and the different pre-sowing seed treatment methods. The base indicators of the photosynthetic apparatus (chlorophyll and carotenoid content, ratio of photosynthetic pigments) were evaluated in the emmer wheat plants as a function of the cultivation technology and pre-sowing seed treatment. The cultivation of the emmer wheat under organic technology was carried out in crop rotation: winter rye – mustard – T. dicoccum wheat. The pre-sowing seed treatment in the traditional technology of emmer wheat cultivation was carried out only by the UV-C irradiation. In the organic technology, both UV-C irradiation and treatment with humic preparation of natural origin “1r Seed Treatment” were used. The content of chlorophyll a (by 9.2%) and chlorophyll b (by 14.5%) increased in the emmer wheat plants under the organic technology cultivation compared to the traditional technology, but with the same method of seed treatment (UV-C irradiation). As a result, the yield increase was 21.0%. The application of the “1r Seed Treatment” humic preparation in the pre-sowing seed treatment led to the increase in yield by ~ 8.0% compared to the plots with UV-C irradiation seeds treatment under organic farming cultivation. An inverse correlation between the ratio of chlorophyll a/ chlorophyll b and the crop yield has been established. The evaluation of economic indicators of the emmer wheat cultivation in the rotation: winter rye-mustard-emmer wheat under organic farming technology, proved its high profitability. So, the photosynthetic pigments’ content and their ratio can be used as the indicators of the efficiency of the introduced elements of agrotechnologies and for predicting future yields.

Published: May 2023

The developmental mechanisms of pathological changes in the oral cavity organs, in particular, periodontal tissues and salivary glands, were elucidated in the model of paclitaxel-induced neuropathy. Experimental studies were performed on 41 white nonlinear rats of both sexes weighing 180–220 g. Toxic neuropathy was modeled by intraperitoneal injection of paclitaxel (Actavis Ltd; series 5GN5122) 2 mg/kg for 4 days (0, 2, 4 and 6). The presence of paclitaxel-induced peripheral neuropathy was confirmed by the Randall-Selitto tensoalgometric test to determine the threshold of pain sensitivity. The total proteolytic activity, total antitryptic activity, and the content of TBA-active products were determined in the homogenate of the rat submandibular and sublingual salivary glands and periodontal soft tissues, content of oxidatively modified proteins, content of average mass molecules and catalase activity; α-amylase activity was also determined in the salivary glands of animals, and the content of free fucose and glycosaminoglycans in periodontal tissues. Paclitaxel-induced neuropathy causes the development of pathological changes in the oral cavity, in particular in periodontal tissues and salivary glands of rats, as evidenced by impaired proteinase-inhibitory potential, intensification of carbonyl oxidative stress, inhibition of protein synthetic function in salivary glands and increased depolymerization of non-collagenous proteins in periodontal soft tissues.
ALTERNATIVE FISTULA RISK SCORE AND FIRST POSTOPERATIVE DAY DRAIN FLUID AMYLASE AS PREDICTORS OF PANCREATIC FISTULA AFTER PANCREATICODUODENECTOMY
Authors: Longo Karina Scalabrin , Bassaneze Thiago , Peres Manuela Corrêa de Toledo , Palma Rogério Tadeu , Waisberg Jaques
Published: May 2023

ABSTRACT BACKGROUND: The high morbidity and mortality rates of pancreaticoduodenectomy are mainly associated with pancreaticojejunal anastomosis, the most fragile and susceptible to complications such as clinically relevant postoperative pancreatic fistula. AIMS: The alternative fistula risk score and the first postoperative day drain fluid amylase are predictors of the occurrence of clinically relevant postoperative pancreatic fistula. No consensus has been reached on which of the scores is a better predictor; moreover, their combined predictive power remains unclear. To the best of our knowledge, this association had not yet been studied. METHODS: This study assessed the predictive effect of alternative fistula risk score and/or drain fluid amylase on clinically relevant postoperative pancreatic fistula in a retrospective cohort of 58 patients following pancreaticoduodenectomy. The Shapiro-Wilk and Mann-Whitney tests were applied for assessing the distribution of the samples and for comparing the medians, respectively. The receiver operating characteristics curve and the confusion matrix were used to analyze the predictive models. RESULTS: The alternative fistula risk score values were not statistically different between patients in the clinically relevant postoperative pancreatic fistula and non- clinically relevant postoperative pancreatic fistula groups (Mann-Whitney U test 59.5, p=0.12). The drain fluid amylase values were statistically different between clinically relevant postoperative pancreatic fistula and non- clinically relevant postoperative pancreatic fistula groups (Mann-Whitney U test 27, p=0.004). The alternative fistula risk score and drain fluid amylase were independently less predictive for clinically relevant postoperative pancreatic fistula, compared to combined alternative fistula risk score + drain fluid amylase. CONCLUSION: The combined model involving alternative fistula risk score >20% + drain fluid amylase=5,000 U/L was the most effective predictor of clinically relevant postoperative pancreatic fistula occurrence following pancreaticoduodenectomy.
Pedidos de desculpas feitos por políticos brasileiros: uma visão da pragmática linguística
Authors: Oliveira Ana Larissa Adorno Marciotto
Published: May 2023

O objetivo deste estudo foi analisar 20 pedidos de desculpas de políticos brasileiros, publicados entre 2010 e 2021, para identificar os elementos linguísticos que os caracterizam, ligados à polidez e à expressão de atitude. Nossa hipótese era de que as expressões de postura e as estratégias de polidez contribuíam para a felicidade dos pedidos de desculpas públicos, atuando, potencialmente, para a conciliação moral entre ofensor e a vítima. Os resultados confirmaram que os pedidos de desculpas de políticos apresentam três características principais: (a) elementos explícitos e convencionalizados de desculpas (IFIDS – illocutionary force indicating devices – Searle, 1969); (b) estratégias de polidez e (c) expressão de atitude. Esses elementos atuaram para que os pedidos de desculpas obtivessem o efeito perlocucionário desejado. Foram também identificados aspectos axiológicos mais amplos, que impactaram o potencial reparador dos pedidos de desculpas.
Influência do suporte parental na intenção empreendedora de estudantes universitários: evidências empíricas no Brasil
Authors: SOARES ANA MARIA JERÔNIMO , MELO FELIPE LUIZ NEVES BEZERRA DE , SAMPAIO LUCIANO MENEZES BEZERRA
Published: May 2023

Resumo Pais empreendedores são importantes agentes para transmitir intenções empreendedoras aos filhos. Estudos recentes têm destacado que a influência parental sobre a carreira empreendedora dos filhos pode aumentar quando os pares forem do mesmo gênero (homofilia de gênero), ou seja, os efeitos tornam-se maiores nas díades pai-filho ou mãe-filha. No entanto, apenas a exposição a pais empreendedores é insuficiente para explicar as intenções empreendedoras dos filhos, visto que dimensões como a natureza da comunicação/interação e até mesmo os incentivos financeiros podem impactar esse relacionamento. Todavia, esses canais de transmissão têm recebido pouca atenção na literatura. Assim, o objetivo deste estudo é examinar se ter pais empreendedores afeta a propensão a empreender dos filhos, analisando quais os principais fatores/canais de transmissão, bem como se a homofilia de gênero exerce papel moderador de tal efeito. A amostra foi composta por 20.623 estudantes universitários que participaram do Global University Entrepreneurial Spirit Students’ Survey (GUESSS) Brasil 2018. Os dados foram analisados por meio de Modelos de Regressão Linear Múltipla e Regressão Probit. Os resultados sugerem que possuir pai empreendedor ou pais (pai e mãe) empreendedores está associado a um aumento na probabilidade de o indivíduo empreender e tal efeito é maior no caso do gênero masculino na díade pai-filho. Ademais, no tocante aos canais de transmissão, constatou-se que a influência parental na carreira empreendedora é exercida, sobretudo, pelos modelos de profissionais que os pais representam (modelagem relacionada com a carreira), comentários/elogios dos pais (encorajamento verbal), bem como pelo incentivo financeiro/material (assistência instrumental).

Abstract In February 2022, Russia invaded the eastern territories of Ukraine. Three days after the invasion, pressured by public opinion and the British government, British Petroleum (BP) announced the abandonment of its almost 20% equity shareholding in Russian state-owned Rosneft at an estimated cost of USD 25 billion for the company. The case puts the reader in the position of CEO Bernard Looney to reflect on the redesign of the company’s strategy with regard to assessing the impact of political risk on its other businesses in the world. The case was designed for undergraduate and graduate students in Business Administration, International Relations, and related areas who want to address topics such as oil geopolitics, business strategy, political risk, and international business.

Published: May 2023

RESUMEN Lilian Harrison fue la primera persona en completar la travesía del Río de la Plata a nado, entre Colonia (Uruguay) y Punta Lara (Argentina) en 1923. La prensa argentina de la época coronó la victoria como un logro de toda la nación, a despecho de las apelaciones sexistas de los reportajes. Este artículo pretende analizar los discursos de la prensa uruguaya sobre la hazaña de la nadadora, utilizando las principales publicaciones periódicas de la época. El análisis de los reportajes permite concluir que, además de los artículos sexistas, que disminuían los logros de la atleta en comparación con sus compañeros masculinos, había cierto nivel de contrariedad en los reportajes, lo que indicaba el desagrado de la prensa hacia los propios nadadores del país.
BAYESIAN CALIBRATION WITH ADAPTIVE MODEL DISCREPANCY
Authors: Leoni Nicolas , Le Maître Olivier , Rodio Maria-Giovanna , Congedo Pietro Marco
Published: May 2023

We investigate a computer model calibration technique inspired by the well-known Bayesian framework of Kennedy
and O'Hagan (KOH). We tackle the full Bayesian formulation where model parameter and model discrepancy hyperparameters
are estimated jointly and reduce the problem dimensionality by introducing a functional relationship that
we call the full maximum a posteriori (FMP) method. This method also eliminates the need for a true value of model
parameters that caused identifiability issues in the KOH formulation. When the joint posterior is approximated as a
mixture of Gaussians, the FMP calibration is proven to avoid some pitfalls of the KOH calibration, namely missing
some probability regions and underestimating the posterior variance. We then illustrate two numerical examples where
both model error and measurement uncertainty are estimated together. Using the solution to the full Bayesian problem
as a reference, we show that the FMP results are accurate and robust, and avoid the need for high-dimensional Markov
chains for sampling.
"I WANT TO MAKE AN IMPACT": THE SCIENCE IDENTITY AND CAREER GOALS OF BLACK AND LATINX SCIENCE AND ENGINEERING POSTDOCTORAL SCHOLARS
Authors: Mendez Sylvia L. , Watson Kathryn , Starkey Kathryn E. , Conley Valerie Martin
Published: May 2023

This instrumental case study examines the science identity and career goals of 16 Black and Latinx science and engineering postdoctoral scholars. Interviews were conducted and grounded by the model of science identity to understand the ways in which science identity develops over time and the influence of race/ethnicity and gender on career goals. Through deductive data analysis techniques, four themes emerged: (1) science competency is built at an early age and solidified in high school; (2) science performance is actualized but questioned in college; (3) science recognition is fostered through professional development and success; and (4) racism and sexism shape the desire to make an impact through a STEM career. Understanding how Black and Latinx postdoctoral scholars' science identity and STEM career goals are nurtured and thwarted within educational systems can be illuminating to those training the next generation of advanced STEM professionals. If the individuals next in line to enter the professoriate are deterred, greater consideration must be given to their experiences.
Green antioxidant composites based on coffee by-products from the alcohol industry
Authors: Terroba-Delicado Enrique , Ivorra-Martínez Juan , Gomez-Caturla Jaume , Sanchez-Nacher Lourdes , Montanes Nestor
Published: May 2023

Bio-based high-density polyethylene (BioHDPE)-loaded composites with different amounts of spent coffee powder (up to 30 wt.%) were successfully produced. The use of coffee residues coming from the alcoholic beverage industry in a BioHDPE matrix resulted in a remarkable improvement in the antioxidant properties of the composites. Waste spent coffee powder reduced the elastic modulus, hardness and storage modulus; the reduction was proportional to the amount of by-product considered. To improve the interaction between the highly hydrophobic BioHDPE matrix and the highly hydrophilic spent coffee powder, a copolymer – namely, poly(ethylene-graft-maleic anhydride) (PE-g-MA) – was used. PE-g-MA addition resulted in an improved interaction between the particles and poly(lactic acid), as confirmed by field emission scanning electron microscopy. On the other hand, the presence of the lignocellulosic filler resulted in a low load transfer between the two components, which led to a decrease in tensile strength. The introduction of coffee powder resulted in an improvement in thermal stability, as confirmed by thermogravimetry and differential scanning calorimetry. Finally, antioxidant activity was also observed in the composites, wherein a 27% reduction in 2,2-diphenyl-1-picrylhydrazyl was reported for the composite with the highest coffee content. The presence of antioxidant substances (coffee oil) was confirmed by Fourier transform infrared spectroscopy.

Bioelectronics is an interdisciplinary field that studies biological material from the conductivity point of view. In case of proteins, the folding is an important feature that directly influences physical and chemical properties. The folding modelling is a hard task. The enormous number of degrees of freedom makes modelling impossible for classical computation due to resource limits. Quantum computations aim to process multidimensional data with logarithmic growth of quantum bits. Quantum operators (gates) form quantum programs, known as circuits that process the input data. In real quantum computers, the gates are noisy and expensive to execute. Thus, it is essential to reduce the number of quantum gates both for the quality of the result and the cost of computations. This work describes an approach to decrease the number of quantum gates based on their mathematical property. The matrix properties form the first optimization technique. In this case, the optimized quantum circuit predicts precisely the same protein folding as the not optimized circuit predicts. This happens because both of the circuits are mathematically equivalent. The removal of weakly-parametrized gates forms the second optimization technique. In such case the optimized quantum circuit calculates the approximate protein folding. The error depends on parameter’s amplitude of the gates. The first technique allows to decrease the circuit depth from 631 to 629 gates while modelling the part of Azurin peptide. The second technique allows to decrease the depth to 314 gates with the threshold parameter value 0.4 radians.

The influence of quartz content (silicon dioxide) on the main physical-mechanical properties of composites based on polypropylene is considered. It is shown that the loading of a compatibilizer – a copolymer of polypropylene with maleic anhydride – into the composition of the composite improves the properties and compatibility of the mixed components of the mixture. Properties such as ultimate tensile stress, tensile yield strength, elongation at break, Vicat softening temperature and melt flow index were studied. The use of synthesized polyethylene wax as a plasticizer made it possible to significantly improve the deformability of highly filled composites. The quartz concentration was varied within 5.0–25 % wt., and the plasticizer concentration was 1.0–3.0 % wt. The method of thermomechanical studies shows the patterns of change in thermomechanical curves in the temperature range of 20–250 °C, depending on the concentration of quartz, plasticizer and vulcanizing agent. The complex of studies carried out has opened up new possibilities for strengthening composites and increasing their Vicat softening temperature.

This article aims to add to the understanding of the challenges involved in designing digital texts to promote multiliteracies pedagogy. A multiliteracies approach calls for multimodal meaning-making and cultural diversity to be integrated into new school curriculum content, and accordingly, we analyse an interactive children’s story app, named Mobeybou in Brazil. The research question addressed was: what can we learn about the design of multimodal texts aimed at promoting intercultural learning from the design of this story app? The app incorporates tangible and digital storytelling materials to promote intercultural skills among young children, focusing specifically on Brazil. Mobeybou in Brazil was studied to characterize the design of its multimodal representations of meaning, using categories from the grammar of storytelling and multimodal meaning-making, particularly those concerned with representing the experiential diversity and personal positioning of the app users. The findings provide evidence of the complexity involved in designing multimodal texts to meet the challenges of promoting multiliteracies pedagogy, highlighting the urgent need to narrow the interface between research undertaken in education, semiotics, and digital media design. The article concludes by identifying the study’s limitations and some future developments.
Зависит ли вероятность рождения ребенка от уровня благосостояния и его субъективного восприятия в российских домохозяйствах: в поиске ответов на извечные вопросы
Authors: Кумо Кадзухиро

В данной статье используются микроданные Российского Мониторинга экономического положения и здоровья населения (РМЭЗ – НИУ ВШЭ) для рассмотрения влияния таких экономических факторов, как доход домохозяйства, зарплата женщин, факторов субъективного благополучия, удовлетворенностью жизнью и состояния здоровья, на вероятность рождения детей в России, которая демонстрировала длительное снижением на протяжении 1990-х годов, а в 2000-2015 гг. увеличивалась. Были получены следующие результаты: более высокие совокупные доходы домохозяйства способствуют деторождению, в то время как более высокая заработная плата женщин ассоциируется с более низкой рождаемостью; респонденты, удовлетворенные своей жизнью и хорошо оценивающие состояние своего здоровья, показывают значительное увеличение вероятности рождения детей. Большинство предыдущих исследований детерминантов рождаемости в России выявили, что доход не оказывает значимого влияния на рождаемость, но результаты, полученные в данном исследовании, позволяют предположить, что это могло быть связано с особыми обстоятельствами начала экономической трансформации в 1990-х годах.

Abstract: Aim: In this research, it is aimed to adapt the “Scale of Active Participation and Unforgettable Cultural Experiences of Tourists” to Turkish language and culture. The measurement tool is a measurement tool to measure the experience levels of individuals who have participated in a tourism event at least once. It offers the opportunity to compartmentalize the cultural experiences that individuals encounter in the tourism activities they participate in. Since the studies on tourism experiences in the Turkish literature are lacking in the field of cultural experiences, it is thought that this research will contribute to the field since there is no measurement tool that can evaluate how much the individuals participating in tourism activities are affected by cultural experiences. Method: The population of the research consists of 402 people selected by convenience sampling method in Eskişehir province. Confirmatory Factor Analysis (CFA) was used to test the structure of the scale. Results: As a result of the analysis, it was revealed that the values of the scale were above the values given for compliance in the literature and were in a positive harmony. At the same time, the construct validity of the scale was tested. The Cronbach Alpha (0.915) internal consistency coefficient for the reliability of the scale, which consists of 4 dimensions and 21 questions, is above the values specified in the literature. According to the findings, it has been determined that the “Tourists’ Active Participation and Unforgettable Cultural Experiences Scale” is a valid and reliable measurement tool. Conclusion: Therefore, it was concluded that the measurement tool, which shows the necessary psychometric properties for Turkish language and culture, can be used for event participants in Turkey.

Abstract: Aim: The aim of this study is to determine the selfesteem levels of university students and the factors affecting them. Method: The research was conducted in descriptive type between March-April 2022. The universe of the research consisted of 456 active students enrolled in the Spring semester of the 2021-2022 academic year at Ardahan University Vocational School of Health Services. The sample of the study consisted of 283 students who voluntarily participated in the research. Research data were collected with the “Introductory Form” and “Rosenberg Self-Esteem Scale”. Research data were analyzed with SPSS 26 package program. Number, percentage, mean and multiple regression analysis were used in data analysis. Results: The self-esteem score of the participants was found to be 20.123±5.31. In the regression analysis of the participants’ self-esteem, the main variables were determined as the economic status of the family, the educational status of the father, and the state of choosing the department willingly. As a result of the analysis, the model was found to be significant (F:2.448, p < 0.001). The adjusted R2 value was 0.089 and the explanatory power of the model was 8.9%. Conclusion and Recommendations: As a result of the research, it was determined that the self-esteem of the participants was above the medium level, and their self-esteem was affected by the economic status, education level of the father, and willingly choosing the department. Low self-esteem can prevent individuals from directing their plans for the future and progressing comfortably when they start working life. For this reason, it is thought that more studies should be conducted to reveal the self-esteem of university students and the factors affecting it, and the attempts that can be made to increase low self-esteem.

Abstract: Aim: The study was conducted to determine the relationship between the ethical sensitivities of aged care students and their attitudes towards the aged. Method: The research was conducted in a descriptive relationship-seeking type with 74 students studying at a state university. Research data were collected with student introduction form, moral sensitivity questionnaire (MSQ), and Kogan’s attitude towards old people scale (KAOP). Results: The mean age of the students participating in the research is 21.24±1.4. KAOP total score was 102.81±60.04 and MSQ total score was 60.04±26.51. Conclusion: As a result of the study, it was determined that the students’ ethical sensitivity levels were high, and their attitudes towards the elderly were positive. It was observed that there was a moderate positive correlation between students’ ethical sensitivities and their attitudes towards the elderly. It is very important to develop a positive attitude towards old age, to prevent negative connotations against the elderly, and to increase ethical sensitivity in the training of professionals who will serve the elderly, in the training of elderly care students who will provide health care services in the future.
