Modeling inflation rate factors on present consumption price index in Ethiopia: threshold autoregressive models approach
Authors: Abebe Alebachew , Temesgen Aboma , Kebede Belete
Published: September 2023

Background

Inflation is the industrious and non-stop ascent in the overall prices of any given commodity in an economy. During the global food crisis, Ethiopia experienced an unprecedented increase in inflation ranked the highest in Africa. It is among the most macroeconomic variable described nonlinear behavior.

Objective

The main purpose of this study was intended to modeling inflation rate factors on present consumption price index (CPI) in Ethiopia: using the threshold autoregressive (TAR) models.

Methods

The study was utilized the secondary data collected from monthly data of CPI for inflation rate from January 1994 to December 2020 which was obtained from central statistical Agency. The forecast was applied between the nonlinear and linear ARMA models using different techniques. The unit root test of Dickey–Fuller test was made for each variables and applied lag length transformation for the variables that had unit root. A threshold autoregressive models was utilized for data handling technique using least square estimation.

Results

The results showed that monthly rate of inflation was characterized a non-constant mean and an unstable variance. The outcome of Tsay tests was revealed that non linearity of CPI and SETAR(2,4,4) had the smallest value of AIC under this study. The forecasting performance comparison results were showed that the nonlinear SETAR model outperform the linear ARMA models. Moreover, the out-of-sample forecast indicates that the CPI of inflation has almost a constant trend. The in-sample forecast using the best-fit asymmetric for the SETAR(2,4,4) model the CPI series exhibits an upward trade until 2012; decreases until 2011; slightly increase up to 2018 and then decrease at the end of the study period.

Conclusion

The superiority in performance of nonlinear models was attributed to their ability to capture the stochastic nature of the monthly rates as evident in the pattern of the forecast errors. The investigators are recommended that using TAR models policy makers can be able to capture the price volatility persistence and also forecasting can be made.
Energy efficiency and greenhouse gas emission abatement opportunities for an existing gas treatment plant: a comprehensive technical and economic analysis
Authors: El-Eishy Mohamed Magdy , Abdelalim Galal Mohamed , Aboul-Fotouh Tarek Mohammad
Published: September 2023

This research paper examined the operational performance and greenhouse gas (GHG) emissions of an existing gas treatment plant. Extensive data collection and analysis were undertaken to assess energy consumption and emissions and identify major emitter units. A GHG emission inventory was developed, and a benchmarking analysis was conducted. The gap analysis revealed excessive emissions, leading to the identification of potential GHG abatement alternatives for the turbo compressor and stabilizer heater. Technical feasibility assessments and economic evaluations were performed for the implementation of waste heat recovery systems, specifically an absorption chiller and a hot oil-driven re-boiler. The results demonstrated significant energy savings, emission reduction, and positive financial returns. The economic evaluation of the abatement opportunities revealed an estimated annual savings of $229,287 US with a simple payback period (SPBP) of 2.96 years and an internal rate of return (IRR) of 32%/year for the absorption chiller. The re-boiler heat system showed an estimated annual savings of $209,456 US with an SPBP of 5.14 years and an IRR of 14%/year. The total investment for both opportunities amounted to $1,755,773 US, with a total annual savings of $438,743 US. The combined SPBP for the opportunities was 4 years, with an IRR of 21%/year. Sensitivity analyses demonstrated the absorption chiller’s financial viability, while the hot oil-driven re-boiler opportunity proved more sensitive to variations in investment costs and savings. Therefore, it is recommended to implement both opportunities together.
Hypercalcemia of Malignancy Complicated by Osteonecrosis of the Jaw Treated With Cinacalcet
Authors: Vasquez Libia , Cortes Tiffany
Published: September 2023

Hypercalcemia of malignancy (HCM) is a common complication seen in patients with cancer and is associated with high morbidity and mortality. Current long-term medical therapy for HCM focuses on inhibiting bone resorption with bisphosphonates or denosumab, which have the rare complication of osteonecrosis of the jaw. This case illustrates cinacalcet as an effective therapy for severe HCM resulting from PTH-related peptide in the setting of osteonecrosis of the jaw. Although the mechanism of action remains unclear, cinacalcet has been successful in other HCM cases even if not associated with elevated PTH-related peptide.
Acquisition of Interleukin-6 Production Ability Over Time With Pheochromocytoma
Authors: Toyoda Yohei , Aiga Ko , Kometani Mitsuhiro , Yoneda Takashi
Published: September 2023

Pheochromocytoma is a tumor of chromaffin cells causing catecholamines overproduction. Interleukin-6 (IL-6), a cytokine, is central to inflammation and immunity. Few studies have reported IL-6–producing pheochromocytoma whose underlying mechanism has not been elucidated. Herein, we present a case of pheochromocytoma whose clinical manifestations changed, and IL-6 levels elevated over time. A 48-year-old woman was referred to our hospital for fever and hepatic dysfunction. Six years prior, a right adrenal tumor was detected during the examination for ovarian teratoma without C-reactive protein (CRP) elevation. Several imaging studies at our hospital showed no abnormalities except for an increase in the size of the adrenal tumor and hepatomegaly. In addition, antibiotics did not improve the fever. Laboratory tests showed elevated levels of CRP with IL-6 elevation. An enlarged adrenal tumor was detected. Administering doxazosin lowered the CRP and IL-6 levels, then IL-6–producing pheochromocytoma was suspected, and adrenalectomy was performed. After surgery, fever and hepatic function were improved, and the CRP and IL-6 levels were normalized. Immunostaining of the resected tissue showed IL-6 focal positivity, which meant the phenotype of tumor cells focally changed their phenotypes over time. IL-6–producing pheochromocytoma should be considered in patients with adrenal tumors and fever of unknown origin.

Published: September 2023

Pregnancy is a state of emergency for most women and is usually a great happiness. Twin pregnancy should bring double happiness. Unfortunately, it often means more problems, more research, more worries. TTTS is a twin-to-twin transfusion syndrome that carries many complications.It occurs in 5-25% of monochorionic twin pregnancies. The severity of the disease is determined using the Quintero scale. The methods of treatment include fetoscopic laser photocoagulation, expectant management, amnioreduction, termination of pregnancy, usually when the fetal lungs are mature. The prognosis depends on many factors, including the type of vascular anastomoses. There are two types of TTTS: acute and chronic.

A ATUALIDADE DO ABSURDO NO TEATRO E NO MUNDO
Authors: Oliveira Mariana
Published: September 2023

Este artigo é fruto de pesquisa associada ao trabalho com o tema do teatro do absurdo em projeto de extensão do CAp-UERJ. Busca responder à inquietante pergunta acerca da atualidade do absurdo no teatro e no mundo. Tem como principal objetivo verificar se o conceito de absurdo, bem como as peças da tendência teatral conhecida como teatro do absurdo, surgida ainda na primeira metade do século XX, ainda nos dizem respeito hoje. Assim, inicialmente, apresenta o conceito formulado por Martin Esslin em sua obra, originalmente lançada em 1961 e intitulada O teatro do absurdo. Em seguida, tece possíveis relações entre a ideia de absurdo e a nossa realidade hoje, por meio de comentários acerca de diferentes situações e fatos que temos vivenciado ou de que temos notícia. Por fim, oferece breve análise acerca de duas peças do gênero estudadas no projeto de extensão que deu origem à pesquisa. Na abordagem de Piquenique no front, de Fernando Arrabal, e O rinoceronte, de Eugène Ionesco, o texto chama a atenção para o interesse que nos despertam em nossos dias. Afinal, chega-se a uma conclusão algo ambígua: o absurdo e seu teatro apresentam-se extremamente atuais, sendo material fértil para diferentes campos da educação, embora, em diversos aspectos, tal verificação não seja exatamente algo a se comemorar.

Grafites da discórdia: o conservadorismo em ação na escola
Authors: De Moura Luís Cláudio Rocha Henriques , De Souza Clóvis Henrique Leite , Witeze Junior Geraldo
Published: September 2023

No final de 2017, como parte das atividades pedagógicas de Artes Visuais orientadas por docentes, estudantes do ensino médio realizaram grafites nas paredes do Instituto Federal de Educação, Ciência e Tecnologia de Goiás (IFG) em Formosa. O esforço analítico neste artigo centrou-se, então, no discurso contrário aos grafites como expressão do conservadorismo no campo educacional, que possuía forte presença em debate na sociedade brasileira naquele momento. No caso em estudo, foi possível perceber que o conservadorismo se coloca em ação no âmbito escolar por meio das seguintes ações: negação do conhecimento acadêmico, crítica às instituições, vigilância à atividade docente, desqualificação do trabalho educativo e disseminação de pânico moral. Para o presente estudo, foram reunidos documentos oficiais com reclamações ou elogios à ação educativa, as respectivas respostas institucionais à ouvidoria e ao Ministério Público, bem como atas de reunião e diversas cartas públicas de apoio elaboradas por ocasião dos fatos. A alteração no padrão visual do campus gerou disputas que explicitaram as divergências ideológicas latentes, trazendo à tona diversos entendimentos sobre o que é arte e como ela deve ser desenvolvida no espaço da escola pública.
Silicon Valley's Team: The Golden State Warriors, Datafied Managerialism, and Basketball's Racialized Geography
Authors: Hughes Kit , Elkins Evan
Published: September 2023

Abstract: This essay examines how the Golden State Warriors' multimedia empire invites viewers to embrace Silicon Valley–driven transformations of space and body that appropriate value generated by Black, Brown, and working-class communities for the benefit of a wealthy, white ownership class. These transformations form part of the tech industry's imperializing adventures in bodily and societal improvement through the intertwined processes of disruption, technological solutionism, datafication, and financial speculation. First, we show how the Warriors promote analytics, wearable technology, surveillance, and white managerialism as keys to success on and off the court. We then turn to the team's 2019 move from Oakland's Oracle Arena to San Francisco's Chase Center, which offered investment and networking opportunities for Silicon Valley elites while making the team less affordable and physically accessible to its traditional Black and working-class Oakland fanbase. Ultimately, we argue that the Warriors promote Silicon Valley processes of wealth extraction by obscuring where and how value is generated, both within the labor relations that define the Warriors' sports organization and in the gentrification of the Bay Area and the commodification of Black Oakland for an increasingly non-Black fanbase.
Nos Vemos en la Cancha : Latinx Women Athletes Making Place in Los Angeles
Authors: Pulupa Kathy
Published: September 2023

Abstract: This essay considers how queer Latinx recreational sporting communities construct homosocial environments through their occupation of public spaces in Los Angeles. Field observations and ethnographic analysis identify how soccer communities provide Latinx women access to homosocial spaces through the social networks they create on and off the fields. The relationships and interactions of the participants in women's leagues serve as case studies of the radical homo-intimate formations within the Latinx community. The amalgamation of homonormative and heteronormative identities within women's teams alludes to the tacit treatment of sexuality within leisure sporting community spaces. The narratives of league women grant an auxiliary conceptualization of Latinx identity formation and negotiations of belonging outside the frameworks of the traditional Latino community and the hegemonic gender and sexual body politics of the US state.
Vanguard of the Athletic Revolution: The Black Panther Party, Micki and Jack Scott, and the Sports Liberation Movement
Authors: Aziz M.
Published: September 2023

Abstract: During the 1970s, the Black Panther Party believed in and provided sports programming that spoke to community embodiment. The Party's approach aligned with what Jack and Micki Scott called "the sports liberation movement." Though understudied in sports history, the Scotts endeavored to create a revolution motivated by the 1968 Olympics. They controversially wrote about and taught sports in a way that prioritized the needs and well-being of professional athletes and everyday people, rather than US patriotism and capitalism consumption. Influenced by fellow leftists like the Scotts, the Black Panthers circulated ideas on freedom and free movement, drawing inspiration from international role models in non-European, socialist countries too. They imagined that socialist sports could escape the militarization of sport in the US and find space for gender inclusion. Their interpretation of socialism showed up in both philosophy and pedagogy, on and off the mat. Using sports archives from the Party as well as broader newspaper research, I contend in this essay that the Panthers, representative of the larger Black Power movement, politicized sport as a necessary site to revolutionize the everyday person's life.
Caracas Is Not Paris: The Moderate Modernity of Mestizaje in Teresa de la Parra’s Ifigenia (1924)
Authors: Alvarez Alana
Published: September 2023

Abstract: Through her epistolary correspondence and her novel Ifigenia 1924, Teresa de la Parra (1889–1936) questions racial stratification systems reminiscent of colonial times and still present in twentieth-century Venezuela. Parra establishes the malleability of racial categories through a moderate racial discourse that intends to re-classify whiteness as the sole marker of economic wealth. Via its young and naïve protagonist, Ifigenia depicts how white elites reluctantly adapted to modernity’s significant socioeconomic changes, leaving previous racial stratification systems—and their whitening projects—obsolete. Parra’s moderate approach to race has been consistently overlooked by numerous scholars who often focus on Ifigenia ’s feminine discourse. However, Parra’s novel thrives in the nuanced juxtaposition between racial purity and mestizaje that mirrors the tension between Paris and Caracas as opposing geographical and racial spaces. Parra’s nuanced discourse reveals a moderate racial theory that underscores the importance of controlled racial mixing and intends to negotiate between a European ideal of racial purity and a Venezuelan mestizo reality at the turn of the twentieth century. Ultimately, her protagonist willingly sacrifices herself for the continuation of a national narrative where modernity has enforced an acceptance of mestizaje .
Enseñanza de español a sinohablantes como especialidad: Origen, hitos y bases conceptuales
Authors: Pena José Miguel Blanco
Published: September 2023

Resumen: Recientemente, la enseñanza del español como lengua extranjera (E/LE) centrada en los estudiantes sinohablantes ha experimentado un gran desarrollo. Sin embargo, los antecedentes y el estado de la cuestión en torno a esta área todavía son bastante desconocidos. Con el presente artículo se pretende paliar en parte esta situación dando a conocer, por primera vez de manera conjunta, el origen, los hitos y el marco conceptual sobre el que se asienta esta especialidad. Para ello, primero, se destacarán algunos hechos relevantes que dan carta de naturaleza a esta disciplina en el ámbito específico del español. Luego, se señalarán varias publicaciones clave donde se plantean las cuestiones fundamentales para la enseñanza de E/LE a sinohablantes. Finalmente, se tratarán algunos conceptos básicos que enmarcan teóricamente el campo que nos ocupa: contexto de aprendizaje , cultura de aprendizaje , cultura de herencia confuciana , cultura china de aprendizaje , estudiante chino , paradoja del alumno chino y paradoja del profesor chino . Nuestro objetivo último no es presentar un estado de la cuestión, sino dar a conocer la perspectiva general en la que se inscribe la enseñanza de E/LE a sinohablantes, así como ayudar a centrar conceptualmente las abundantes investigaciones que se realizan en torno a este dominio en la actualidad.
Ideologías raciolingüísticas en Colombia: Análisis discursivo y racial de la representación del bilingüismo en las políticas lingüísticas y en la prensa
Authors: García León David L. , García León Javier E.
Published: September 2023

Resumen: Este trabajo aboga por una mirada raciolingüística e interseccional para comprender las políticas lingüísticas (PL) y los discursos sobre bilingüismo en Colombia. Primero, se describen las PL y se clasifican los estudios realizados a dichas políticas. Posteriormente, se caracteriza el enfoque interseccional y raciolingüístico y se presentan los resultados de un estudio cuya pregunta de investigación fue: ¿Cómo se construyen discursivamente las ideologías raciolingüísticas sobre el bilingüismo en Colombia? Para responder esta pregunta, se analiza un corpus de PL y artículos periodísticos con una metodología que combina la perspectiva raciolingüística interseccional con el Análisis Crítico del Discurso. De la clasificación de los estudios previos, se encontró que a) son pocas las contribuciones que analizan conjuntamente las políticas para lenguas mayoritarias y minorizadas; b) no se asume un enfoque interseccional en estos estudios; y c) no existen trabajos que vinculen las PL con los imaginarios que circulan en medios de comunicación. Los resultados del estudio muestran que las ideologías raciolingüísticas se construyen por medio de a) la invisibilización de las tensiones entre PL para lenguas minorizadas y mayoritarias; b) una jerarquía raciolingüística de los hablantes y sus lenguas; y c) el encubrimiento de las colonialidades epistémicas y raciales.
Pero habla(n): Las heridas de los hijos de los inmigrantes en la poesía de Paloma Chen
Authors: Esteban Ester Hernández
Published: September 2023

Resumen: La población inmigrante es una presencia estable en el tejido social peninsular. Los estudios culturales sobre inmigración han analizado cómo modifica la identidad española, sin embargo, este artículo ahonda sobre la experiencia de la segunda generación como miembros activos de la sociedad española. Este artículo realiza una lectura detallada del primer poemario de la poeta sinodescendiente, Paloma Chen. Siguiendo el análisis de los espacios liminales de Homi Bhabha y Edward Soja, sitúo su poética en el tercer espacio de la inmigración, en el cual propongo que residen las subjetividades trasversales, aquellas que atraviesan de manera perpendicular ambas culturas, pero cuya división no es paralela o estable sino fluida. En su poesía hay tres temas que la posicionan como subjetividad transversal: primero, la crisis de identidad que sufren los hijos de inmigrantes que se encuentran entre dos culturas, dos idiomas y dos conjuntos de expectativas. Segundo, la desestabilización de estereotipos, como minoría silenciosa o “peligro amarillo”, para denunciar el racismo al que tienen que enfrentarse las minorías racializadas en España. Tercero, la presencia constante de “la herida” como figura literaria sirve como espacio liminal de unión e intervención para las subjetividades transversales frente a la hegemonía.
Nonhuman Animals and Hope: Kazuo Ishiguro's Never Let Me Go and Philip K. Dick's Do Androids Dream of Electric Sheep
Authors: Rando David P.
Published: September 2023

Abstract: What can critical animal studies learn by temporarily directing attention away from representations of nonhuman animals in literature? Kazuo Ishiguro's Never Let Me Go and Philip K. Dick's Do Androids Dream of Electric Sheep? allow readers to experience the hopes of engineered or artificial nonhuman creatures. Without presuming to know the unknowable or to make the animal speak, these novels help to further animal liberation discourses by democratizing the ostensibly human concept of hope, opening new paths of empathy between nonhuman and human animals while making it harder to accept the instrumentalization of nonhuman animals under anthropocentric capitalism.
Irvine Welsh, Neoliberalism, and the Lumpenproletariat
Authors: Clarke Ben
Published: September 2023

Abstract: This essay demonstrates the continued critical value of Marx and Engels's idea of the lumpenproletariat for contemporary analyses of growing populations excluded from the recognized economy. Focusing on Irvine Welsh's work, I argue that the lumpenproletariat exposes the ideological continuities between marginalized groups and dominant classes. This relation is central to Welsh's fiction, which challenges the simple identification of the outsider and the radical. Welsh's insistence on the agency of the dispossessed extends existing models of the lumpenproletariat, enabling new, more inclusive forms of radical theory and practice.
"Floated invincibly": Animating Character in Marcel Proust's In Search of Lost Time
Authors: Weidman Pamela L.
Published: September 2023

Abstract: This essay uses early twentieth-century animation to understand Marcel Proust's surprisingly minimalist approach to detail, and how In Search of Lost Time reworks the connection between the limits of description and autonomous character. Proust's Search and films by Georges Méliès and Émile Cohl share a guiding concern with how to bring characters "to life" out of relatively simple elements. In his attempts to understand others, Proust's Narrator returns to a few typifying details, and layers them against changing backgrounds, so that his characters remain identifiable even as they undergo continuous social and aesthetic transformations, beyond the purview of his gaze. As well as informing an approach to Proustian character, this essay illuminates the films' staging of elaborate ethical encounters between animator and character. In this way, the techniques of animation provide a set of cross-medial tools for understanding aesthetic vision and character at the start of the twentieth century.
Ted Hughes, the Goddess and ‘An Alchemy’
Authors: Skea Ann
Published: September 2023

Two of the books Ted Hughes took with him when he worked as a Royal Air Force (RAF) fighter plotter during his two years of compulsory national service, were Robert Graves’s The White Goddess and The Complete Works of William Shakespeare. Both, he read closely and often. He was already familiar, through his interest in the magical preoccupations of W. B. Yeats, with the philosophy of Hermetic Neoplatonism which had made its way to England during Shakespeare’s time and influenced the work of poets like Sir Philip Sidney, Gabriel Harvey and Edmund Spencer. All of these poets believed in, and used, the alchemical power of poetry which, as Sidney wrote in his Defence of Poetry, could ‘hold children from play, and old men from the chimney corner. And pretending no more, doth intend the winning of the mind from wickedness to virtue’. This, and his immersion in Shakespeare’s work (which as Sylvia Plath told her mother, he ‘knew by heart’) led Hughes to discern a developing pattern, based on the transformative powers of the Goddess, through which he believed Shakespeare was performing a complex alchemical process. He expounded this theory in detail in Shakespeare and the Goddess of Complete Being, but almost twenty years earlier he had written the poem ‘An Alchemy’ for a limited edition anthology published in 1973 by the Globe Theatre Trust. ‘An Alchemy’ is a difficult and allusive poem in which nothing is spelled out. In this article, I look at just one section of the poem in which Hughes created his own alchemical matrix through which he sought to reveal the underlying alchemical theme that he saw as the ‘Gold’ in Shakespeare’s work.

A critical review of international research into pre-service teachers’ beliefs and practices when teaching migrant learners
Authors: Hanna Helen
Published: September 2023

This article provides a critical qualitative review of 26 English-language journal articles from multiple countries that focus on research and practice among pre-service teachers, and their beliefs about, and experiences of, teaching migrant learners. The findings are organised around two themes. First, the review reveals that student teachers are more likely than not to hold negative beliefs and harbour anxieties about teaching migrant learners. While the cultural diversity of the country in which the student teachers are working does not seem to be a strong determinant of such beliefs, research suggests that such beliefs are more often linked to a lack of knowledge and training. Second, the review identifies a strong emphasis on belief in the value of empathy in learning to teach migrant learners, with the caveat that having a migrant background does not necessarily lead to a more empathetic student teacher. The wider discussion problematises empathy as a goal of training and highlights the challenges inherent in encouraging the development of critical self-reflection among pre-service teachers. The review ultimately questions the extent to which pre-service teacher education equips pre-service teachers to work effectively with migrant learners and proposes increased collaborations between researchers and pre-service teachers as a step towards expanding critical research and practice.

The biocompatibility of toothpaste in an oral cavity should be approved by clinical trials. Nowadays, herbal toothpaste is increasing in popularity due to its natural ingredients. Being genetically similar to humans, zebrafish are used in potential toxicity testing. The zebrafish embryotoxicity test is a fast and straightforward method to study chemical toxicity during embryogenesis. Objective: This study aimed to evaluate if there was any biocompatibility of the toothpaste on zebrafish embryos. Methods: Adult AB strain zebrafish were used according to Institutional Animal Care and Use Committee protocols. Normally dividing, spherical embryos were exposed to herbal toothpaste with ginger (Gumgumix, Turkey) (50 mg/L) and conventional toothpaste (Signal, Expert Protection, Bulgaria) (50 mg/L) in well plates containing 20 embryos, having four replicates. Developmental effects, mortality, and hatching rates were evaluated for 72h. Results: Zebrafish embryos exposed to conventional toothpaste had a higher mortality rate than those exposed to herbal toothpaste; they hatched later and delayed in development. There was no difference between herbal toothpaste and the control group regarding mortality and hatching rates (p > 0.005). Conclusion: The herbal toothpaste showed higher biocompatibility on zebrafish embryos compared to the conventional toothpaste under the condition of this study.

Education Leadership: Legal and Social Impacts of Public Schools Leadership and Management on the City of Baltimore Maryland, United States of America
Authors: Anucha Hyacinth
Published: September 2023

This study assessed the correlation between per student expenditure and academic achievement, examining legal issues, poverty, and crime as chronic factors impacting low academic performance as parents’ legal actions against the City School Board of Commissioners question the effectiveness of public school spending. Ineffective leadership, mismanagement, poverty, and crime contribute to subpar performance, necessitating new strategies for learning, teaching, and meeting high academic standards. The Baltimore City public school system has faced challenges in academic achievement, poverty, and crime over the past decades. Maryland's Blueprint for the Future and meta research emphasize the importance of effective leadership and quality education to enhance student achievement, socioeconomic growth, and reduce crime. The present research analyzed various factors influencing public school performance, including per teacher and pupil expenditure, while correlating SAT and ACT scores with academic improvement in Baltimore City, Maryland. Besides, it is declared that effective educational leadership is imperative in a data driven culture whose challenges lie not in advanced technology itself but rather in the transformation of repressive cultures, teams, and practices.
Transferring effective learning strategies across learning contexts matters: A study in problem-based learning
Authors: Saqr Mohammed , Matcha Wannisa , Ahmad Uzir Nora'ayu , Jovanovic Jelena , Gašević Dragan , López-Pernas Sonsoles
Published: September 2023

Learning strategies are important catalysts of students’ learning. Research has shown that students with effective learning strategies are more likely to have better academic achievement. This study aimed to investigate students’ adoption of learning strategies in different course implementations, the transfer of learning strategies between courses and relationship to performance. We took advantage of recent advances in learning analytics methods, namely sequence and process mining as well as statistical methods and visualisations to study how students regulate their online learning through learning strategies. The study included 81,739 log traces of students’ learning related activities from two different problem-based learning medical courses. The results revealed that students who applied deep learning strategies were more likely to score high grades, and students who applied surface learning strategies were more likely to score lower grades in either course. More importantly, students who were able to transfer deep learning strategies or continue to use effective strategies between courses obtained higher scores, and were less likely to adopt surface strategies in the subsequent course. These results highlight the need for supporting the development of effective learning strategies in problem-based learning curricula so that students adopt and transfer effective strategies as they advance through the programme.
Implications for practice or policy:

Teachers need to help students develop and transfer deep learning as they are directly related to success.
Students who continue to use light strategies are more at risk of low achievement and need to be supported.
Technology-supported problem-based learning requires more active scaffolding and teachers’ support beyond “guide on the side” as in face-to-face.
Improving and analysing the spectral access performance of QAM-64 optical NOMA using a hybrid ED-CSD algorithm
Authors: Kumar Arun , Gaur Nishant , Chakravarti Sumit
Published: September 2023

Cognitive radio (Cr) is one of among the most promising developments, which combines optical non-orthogonal multiple access (O-NOMA) methods to increase the fifth generation (5G) spectrum’s usage efficiency. In this work, we provide a hybrid approach based on cyclic stationary feature detection (CFD) and energy detection (ED). The probability of false alarm (PFA), on which it is based, is used to choose which spectrum sensing (SS) approach to use. When PFA is less than 0.5, the ED is chosen; otherwise, the MF is. The suggested detection method in O-NOMA is investigated using Matlab-2016 simulation with reference to several metrics, such as bit error rate (BER), signal-to-noise ratio (SNR), probability of detection (PD), and PFA.
The therapeutic effect of oral desmopressin lyophilisate formulation in children with central diabetes insipidus
Authors: Korkmaz Hüseyin Anıl , Coşkunol Fulya , Barışık Vatan , Ozkan Behzat
Published: September 2023

Objectives

We aimed to assess the efficacy of oral use of oral desamino-D-arginine-8-vasopressin lyophilisate (OLD) in children with central diabetes insipidus (CDI).

Methods

Clinical, laboratory, and imaging characteristics of twenty-five children with CDI treated with OLD were evaluated.

Results

Fourteen boys and eleven girls with a mean age of 52.37 months were evaluated. These children (mean weight and height at admission, 26.81 ± 14.8 kg vs. 92.52 ± 30 cm) presented with failure to thrive, irritability, prolonged fever, polyuria and hypernatremia (mean sodium level, 143.12 ± 8.6 mEq/L). At the time of hypernatremia, mean serum and urine osmolality were 298.2 ± 18 mOsm/kg and 160.20 ± 8.7 mOsm/kg, respectively. ADH levels were undetectable (<0.5 pmol/L) at admission in all cases. Oral administration of desmopressin lyophilisate (120 µg/tablet) was initiated at a dose of 5 μg/kg/day in two divided doses together with controlled water intake to avoid hyponatremia. Serum sodium levels normalised in a mean duration of 15.2 ± 16.4 h with a mean decline rate of 0.12 ± 0.04 mEq/L/h. Nine children needed rehospitalization because of hypernatremia due to non-compliance. Four episode of hyponatremia was observed. Weight gain and growth were normal during the mean follow-up duration of 37.79 ± 48.2 months.

Conclusions

Administration of OLD was practical and safe in the treatment of CDI in children with CNS malformations in this small retrospective series.

Great potentials of lignin-based separator for Li-ion battery with electrospinning in aqueous system
Authors: Zhang Weipan , Hao Pengfei , Lei Lirong , Hou Yi
Published: September 2023

Separator plays a key role in the safety and performances of lithium-ion batteries with the needs of good thermal stability and wettability. Compared with the commercial separator mainly made by polyolefins in organic solvents, the electrospinning of lignin/polyvinyl alcohol in an aqueous solution has been investigated as a green and economically viable method to produce high-performance separators without any other chemical additives. Lignin/polyvinyl alcohol (mass ratio: 3:7) nanofiber separators outperform commercial polypropylene separators in terms of porosity (71 %), liquid absorption (373 %), and outstanding thermal stability at 200 °C. Additionally, Li-ion battery cells that were constructed using different separators were assessed to demonstrate favorable electrochemical performance. The results showed that fabricated Li-ion battery with Lignin/polyvinyl alcohol (mass ratio: 3:7) nanofiber separators possesses a superior capacitance of 154.1 mA h g−1 at 0.5 C, and maintained outstanding cycle stability after 50 times of charging and discharging process at 0.5 C with the capacitance retention rate up to 98.7 %. The facile and sustainable synthesis strategy of lignin-based separator materials for Li-ion batteries developed in this work provides new perspectives for related research, especially based on environmentally friendly aqueous systems.
Failure criteria and microstructure evolution mechanism of the alkali–silica reaction of concrete
Authors: Wang Yongbo , Gao Peng , Su Huaizhi , Qin Yuanyu , Wang Yimeng , Xue Gang
Published: September 2023

In this study, the influence of two distinct reactive aggregate dosages on the alkali–silica reaction (ASR) of concrete was investigated. The expansion ratio, axial compressive strength, splitting tensile strength, and relative dynamic elastic modulus (RDEM) of concrete were considered as the main parameters to study the failure criteria of concrete induced by ASR at 40°C. Microscopic experiments, such as scanning electron microscopy and X-ray computed microtomography, were applied to analyze the damage induced by ASR on the concrete prisms and the propagation of internal cracks of the reactive aggregates in nanospace. The results showed that the two ranges can be used as the failure criteria produced by the ASR of concrete containing 3 and 6% dosages of reactive aggregates at 40°C, respectively, when the RDEM of concrete was reduced to 70‒75% and 85‒90%. Additionally, the results of CT indicated that microcracks tended to extend from the initial defects of aggregate to the cement slurry. Meanwhile, ASR gel packed with the pores, which reduced the porosity. It was noteworthy that the adhesive force between the ASR gel and the cement matrix after filling pores could not make up for the loss of the mechanical properties of concrete.
Influence of tetrabutylammonium bromide based ionic liquid on the aggregation behavior of dodecyltrimethylammonium bromide in the range (293.15 K–313.15 K): acoustic and volumetric investigation
Authors: Hooshyar Hossein , Sadeghi Rahmat
Published: September 2023

The effect of the ionic liquid analogue tetrabutylammonium bromide on the aggregation behaviour of the cationic surfactant dodecyltrimethylammonium bromide in aqueous medium was investigated with volumetric and compressibility measurements over a wide temperature range (293.15–313.15) K. The data obtained were used to obtain density data. Based on the density data obtained, the volumetric properties (apparent molar volumes and partial molar volumes) of the surfactant in unimeric and micellar forms were evaluated and discussed in terms of the respective ionic and dipolar interactions. The data obtained were analysed to determine the effects of (i) temperature and (ii) salt added to the surfactant. The results were also interpreted in terms of the molecular interactions occurring in the binary mixtures of the present study. The addition of tetrabutylammonium bromide has a lowering effect on the CMC values of the surfactant studied in aqueous medium.
PARCOURS DE LA RECONNAISSANCE DANS L’IDEALISME ALLEMAND ET SA RECEPTION EN HEGEL
Authors: Balbontin Cristobal
Published: September 2023

Une étude du concept de reconnaissance chez Hegel demande une attention particulière à la pensée de Fichte et à son élaboration de la reconnaissance aussi bien que l’influence de Schelling. Notre propos est de montrer que le concept de reconnaissance, loin d’être une notion simple à exposer, se montre dans une multiplicité de niveaux de l’architecture hégélienne tout en étant soumis á une influence à géométrie variable des différents philosophes. Ainsi, tout en se rapportant les uns des autres de façon complexe, ces niveau et influences jouent à leur tour avec une ensemble d’autres concepts fondamentaux de la pensée hégélienne qui font partie aussi des enjeux critiques de l’idéalisme allemand.
Top Ten Breakthroughs in Clinical Hypertension Research in 2022
Authors: Yang Qiaoxi , Cai Jun
Published: September 2023

Hypertension is a major global public health concern whose disease burden affects an estimated 1.4 billion people worldwide and is associated with 10.8 million deaths annually. Despite substantial advances in medical care, the prevalence of hypertension has markedly increased, owing to population aging; poor treatment adherence; and increases in risk factors, such as excessive salt intake, and overweight and obesity. Consequently, the disability-adjusted life years have increased by 40%, primarily because of elevated risk of stroke, coronary atherosclerosis, heart failure, and kidney failure. Major outstanding problems associated with the treatment and management of hypertension include determining optimal blood pressure targets, developing innovative antihypertensive medications and devices, and implementing effective and feasible hypertension management strategies. To address these challenges, numerous clinical trials are currently underway. This article highlights the most influential ten clinical studies on hypertension in 2022. The rational use of antihypertensive medications is concluded to be important for effective hypertension management. Important considerations include medication types and dosing times; optimal blood pressure targets; the development of new drugs and therapeutic devices; specific community characteristics, such as village doctor-led care; and healthful diets.
