The US as a Queer Heterotopia: Carlos Fuentes and Viet Thanh Nguyen
Authors: Quintana-Vallejo Ricardo
Published: April 2024

Abstract: Does queer desire require displacement to become intelligible? Coming-of-age narrative fictions centering queer experiences, desires, and communities often set their formative processes in liminal spaces. The mobility away from home and toward queer sites is extreme when characters leave behind their countries. In the case of two short stories set in the 1970s, Carlos Fuentes's "La pena" ( La frontera de cristal , 1995) and Viet Thanh Nguyen's "The Other Man" ( The Refugees , 2017), US cities serve as the sites where two young migrants undergoing processes of self-exploration face experiences of cultural shock that force them to reevaluate their assumptions about their sexuality. Their struggles overlap with their negotiation of their national identities: how can they desire same-sex partners and be Mexican or Vietnamese? This study analyzes the formative processes of two young men as they identify (and disidentify) with the heteronormative expectations of their cultures of origin and within the US.
COVID-19 Pandemic Effects on Student Efficacy in Jazz Performance and Improvisation in Secondary School Musicians
Authors: Brumbach Glen Alan
Published: April 2024

Abstract: This study investigated the effects of the COVID-19 pandemic on secondary students' self-efficacy in jazz performance and improvisation. Students ( n = 38) from secondary-school jazz ensembles attending a jazz festival in a Southwest state participated in a questionnaire about their perception of achievement in jazz performance and improvisation during the 2020–2021 school year with COVID-19 restrictions in place and the year after when restrictions had been eased. Jazz ensemble directors ( n = 8) were interviewed about their experiences and positive and negative outcomes of the two years pertaining to students' self-efficacy. A paired two-tailed t-test revealed that students had a significantly higher self-efficacy perception after restrictions were lifted in jazz performance and improvisation. Directors reported increased competency with technology and a drop in enrollment in their jazz ensembles. Directors also experienced a shift in their educational philosophy, opting for a more empathetic as opposed to a results-based approach to student achievement.
Mapping the Scene: Creative Ecosystems in Post-Secondary Jazz Education
Authors: Hertzog Jacob , Hunter Justin R.
Published: April 2024

Abstract: The jazz world is built on exploration and innovation, which makes the genre and its practice tediously difficult to define. Practitioners use performance spaces as venues to not only share their art but to teach new musicians. That model is hard to replicate, but music programs in higher education have sought to do this since the 1940s. As part of that practice, we theorize that the institutional environment, particularly in the creative disciplines, is a critical input factor for jazz programs necessitating further research. This study investigates the creative ecosystem in jazz degree-granting institutions (JDGI; n = 90) through a mapping of higher education programs offering jazz degrees. We use these data to create a profile of an archetypical collegiate jazz program and present a snapshot of contemporary jazz education while offering a novel baseline for future research in the field.
George Russell, the Lydian Chromatic Concept, and Black Student Protest at the New England Conservatory
Authors: Stucky Rami Toubia
Published: April 2024

Abstract: This paper looks at composer and theorist George Russell and the impact his Lydian Chromatic Concept had on Black student activism at the New England Conservatory (NEC) during the late 1960s and early 1970s. I expand on the work of scholars who have explored how Russell's concept reflected the spirit of the civil rights era by showing how students were thinking of it as more than simply sonic freedom and in the ways it affirmed Black life at a predominantly White music institution. Scholars have been increasingly advocating for the incorporation of "fugitive music theorists" such as Russell into undergraduate and graduate music curriculum and this article joins such calls. Relying on conservatory library archives as well as oral interviews with alumni, I argue that Russell's theories served as a musical and political muse for activists in the Creative Black Artists (CBA) student union during an era of curriculum reform and nationwide student protest. In doing so, this article hints at the impact such theories would have on students in the twenty-first century.
Wynton Kelly's Bounce
Authors: Benatar Jeffrey
Published: April 2024

Abstract: Wynton Kelly is known throughout the jazz world as an expert accompanist, a bluesy soloist, and a skilled pianist. As a result, most jazz pianists have transcribed his work. The most elusive element of Kelly's playing is his patented bounce. This article analyzes Kelly's transcribed solo on "Blues on Purpose" from the Undiluted trio album with Paul Chambers on the bass and Jimmy Cobb on the drums; it was recorded in 1965 and was released by the Verve label. Through deep analyses of entire or excerpted materials from the first, fifth, ninth, tenth, and eleventh choruses (out of 15 total), techniques essential to Kelly's bounce will be demystified. The three primary areas selected in order to illuminate Kelly's bounce were left-hand techniques, right-hand melodic language, and rhythmic strategies. Further, suggested exercises or application of these practices will be shared so that you can add bounce to your next solo.
Muslim Religious Identity Formation: Factors that Promote a Muslim Religious Identity among a Sample of Muslim College Students
Authors: Aziz Majdouline , Aziz Mazen
Published: April 2024

Abstract: Few studies within religious identity literature have focused on how religious identity is developed within the American Muslim population. Considering the growing number of Muslims in the United States and the need to expand our understanding of this population specifically, and of religious identity formation more generally, this study examined predictors of Muslim religious identity among a sample of self-identified Muslim students (N=194). Multivariate linear regression analysis examined the relationship between Muslim religious identity and self-identification, sense of belonging, affirmation, religious involvement in ritual practices, family characteristics, peer characteristics, structured organizational involvement, area of residence, college, and the experience of a crisis. Hierarchical regression analysis was used to assess whether the experience of a terror event explained a significant proportion of the variance in Muslim religious identity. The analyses yielded self-identification, sense of belonging, affirmation, suburban area of residence, and the experience of a crisis as significant predictors of Muslim religious identity. The study further revealed that although the experience of a crisis did explain a significant proportion of Muslim religious identity, self-identification, sense of belonging, and affirmation were stronger predictors. Implications of these findings are discussed.
Bediuzzaman Said Nursī’s Critique of the Concept of Waḥdat al-Wujūd (The Unity of Being)
Authors: Frolov Albert
Published: April 2024

Abstract: This article reflects on the critical reception within the Islamic world of waḥdat al-wujūd (the unity of being), the famous Sufi notion associated with the works of the Muslim mystic-philosopher Muḥyī al-Dīn Ibn ‘Arabī (d. 1240 CE), with a particular focus on the ways in which it was critiqued by the modern Islamic scholar Bediuzzaman Said Nursī (d. 1960). Nursī’s work is significant in that his critique of waḥdat al-wujūd was conversant with pre-modern Islamic intellectual discourse even as it attempted to render it compatible with modern needs and subjectivities. To better understand Said Nursī’s approach to waḥdat al-wujūd , this article situates it within this broader discursive context, specifically drawing on its connections to the critiques offered by Sa‘d al-Dīn al-Taftāzānī (d. 1390 CE) and Aḥmad Sirhindī (d. 1624 CE), both of whom would be influential on Nursī’s work. This article concludes by suggesting that despite Nursī’s criticism of and attempts to replace waḥdat al-wujūd with an alternative spiritual method, his thought is nonetheless deeply reliant on concepts articulated by Ibn ‘Arabī and his followers.
Sniffing the Jar: Metaphor and Body in the Story of the Encounter between Shmuel and Rav
Authors: Fraenkel Yuval
Published: April 2024

Abstract: This article analyzes the talmudic story of the first encounter between Rav and Shmuel (b. Shabbat 108a). It focuses on the structural difficulties of the plot, particularly the relationship between Rav’s interview at the beginning of the story and the aggressive medical treatment he undergoes at the end. A new interpretation of Shmuel’s request of his student Karna to “sniff Rav’s jar” can solve these problems. The request is here understood as a play on words, which concretizes the metaphorical idiom. This interpretation enables a new reading of the entire story, as one that centers on the relationship between metaphor and reality and, by extension, between the Torah and the body of the immigrant sage.

3D nasoalveolar moulding: A complete digital workflow model
Authors: Deepak Singh  , Tulika Tripathi  , Priyank Rai
Published: April 2024

Nasoalveolar moulding (NAM) is a paradigm shift from the presurgical orthopaedics used extensively over the past 20 years in infants with cleft lip and palate. It has been proposed that the gap between the clefted segments be filled up before surgical repair via presurgical nasoalveolar moulding. To attain the best practical and aesthetic results, it is a straightforward yet effective treatment that must be started at the appropriate age and time. In order to enhance treatment outcomes, convenience of use, compliance, and cost-effectiveness, recent developments in NAM therapy have focused on implementing changes to the nasal stent or intraoral moulding plate. Specifically, 3D technology has been used to improve the efficiency of NAM device design and develop standardised, objective methods of determining progressive morphological changes during therapy. The article discusses various methods that use 3D printing technology to produce tangible components from a virtual therapeutic strategy. It also looks at how developments in computational methods and printing materials could open up novel opportunities for computer-assisted NAM therapy.

Authors: Markova M. G. , Somova E. N.
Published: April 2024

The aim of the research was to optimize the clonal micropropagation of stone crops through the use of improved techniques. The objects of the research at the stage of introduction into culture in vitro were meristematic apexes, at the stage of micro-propagation itself – micro-shoots, at the rooting stage – rooted micro-shoots, at the adaptation stage – micro-plants. All experiments were carried out according to generally accepted methods using the example of the steppe cherry variety Shchedraya, the domestic plum variety Kazanskaya and the hybrid sweet cherry Fatezh. As a result of the research, it was found that the use of a 10 % chlorhexidine solution for sterilization of the initial plant material of stone crops increased the survival rate of apexes on average by 2.4 %; the combined use of growth regulators 6-benzylaminopurine 0.5 mg/l, gibberellic acid 0.2 mg/l, indo-lil-3-butyric acid (IBA) 0.2 mg/l in a nutrient medium and an experimental diode pulsed phytoirradiator in the last proliferation passage activated the proliferation of micro-shoots, increasing the reproduction coefficient of stone crops in 6 passages by an average of 0.9 pcs/explant; the addition of 1.0 mg/l (IBA ) to the nutrient medium provided an increase in the rooting capacity of micro-shoots of stone crops by an average of 9.6 %. The treatment of micro-plants of stone crops at the stage of adaptation by spraying with an 8 % solution of the extract of the products of the larvae of the large wax moth and the use of an experimental LED pulsed phytoirradiator with a mixed spectrum contributed to an increase in their survival rate by an average of 12.4 %. Compliance with the proposed improved methods of clonal micropropagation of stone crops using growth regulators and an experimental LED pulse phytoirradiator with a mixed spectrum made it possible to increase the yield of standard adapted micro-plants by 2 times. At the same time, the cost of one adapted micro-plant decreased by an average of 11.4 rubles, and the profitability of obtaining improved stone crop material increased by 33.7 % and amounted to 160.7 %.

Published: April 2024

Trigonometry plays an important role in the field of mathematics education, but in fact, some errors are identified. Therefore, this study aims to explore the students’ errors in solving trigonometry problems, especially in the sub-topics of trigonometric ratios. This is a qualitative study using a case study design. The subjects of this study were 35 students in grade 10 in one of the senior high schools in a district located in the Province of East Kalimantan. The research instruments were 1) a diagnostic test consisting of five essay problems about trigonometric ratios; 2) observation sheets; and 3) interview guidelines. The data was analyzed through three processes. They were: 1) data reduction, 2) data presentation, and 3) conclusion drawing or verification. The results show that the subjects made errors in solving trigonometric ratio problems, with the most errors made by subjects being errors in understanding concepts and writing algorithms. The causes of students making errors are due to the weak understanding of students' concepts, lack of student mastery of the prerequisite topics, the problems given being less varied, and students being in a hurry to solve problems.

Purpose. Study of the influence of prebiotic feed additives on the physicochemical parameters of fat-tail fat of Kalmyk breed rams. Materials and Methods. When fattening animals using lactulose-containing additives in their diets, the generally accepted VIJ method was used, and the phyco-chemical properties and composition of fat-tail fat were carried out in certified laboratories according to the methods provided for by GOSTs. The resulting digital material was processed using the statistical package Microsoft Excel, and the reliability of the data was checked using the Student's criterium. Results. Feeding prebiotic additives “Laktuvet-1” and “LaktuSuper” to fattening rams affected the melting point of fat-tail fat of both 4- and 7-month-old animals. A decrease in the melting temperature of fat was recorded in experimental group I by 0.14 and 0.26°C (P≤0.05), in experimental group II – by 0.21 and 0.32°C (P≤0.01) compared with the control group. The iodine number of fat significantly increased in animals of the experimental groups of 4 months of age by 0.39 (P≤0.05) and 0.51 (P≤0.05), of 7 months of age – by 0.58 (P≤0.05). 01) and 0.76 (P≤0.01) compared to the control group. In the fat-tail fat of 4-month-old rams, compared with the control, the content of unsaturated fatty acids increased in experimental group I by 1.72% (P≤0.05), essential fatty acids in experimental group II – by 2.26% (P≤0.01), the total level of saturated fatty acids decreased in both experimental groups. At the age of 7-month rams in experimental groups I and II, among monounsaturated fatty acids, a significant difference compared to the control was obtained only in the content of oleic acid in fat-tail fat, which was 0.34 (P≤0.05) and 0.42% (P≤0.01). The amount of unsaturated fatty acids significantly exceeded this indicator in the control group by 0.53 (P≤0.01) and 0.83% (P≤0.01). The decrease in the amount of saturated fatty acids in the experimental groups was ensured by a significant decrease in the content of palmitic acid in fat-tail fat by 0.31 (P≤0.05) and 0.44% (P≤0.01) and stearic acid by 0.20 (P≤0.05) and 0.27% (P≤0.05) compared to control. Conclusion. The feed additives “Lactuvet-1” and “LactuSuper” had an effective effect on the composition and physicochemical properties of fat-tail fat of fattening rams. The active substances of prebiotic additives helped to reduce the melting point and improve the chemical and fatty acid composition of tail fat.

Purpose. Identification of the impact of new feed additives "Kumelact-1" and "Di-lactocin-Ya" on the physicochemical properties of broiler chicken meat. Materials and Methods. The object of research was broiler chickens and exposure to the feed additives Kumelact-1 and Di-lactocin-Ya. Chimic and biochemical compositions of thoracic muscles of broilers, the content of mineralic substances in thoracic muscles, amino acid and fatty acid co-stars of thoracic muscles were determined by conventional methods according to GOST. Results. Studies have shown the positive effect of the additives “Kumelakt-1” and “Di-lactocin-Ya” on the chemical composition of poultry products. A decrease in fat and an increase in protein in meat has been established. Also, the use of these feed additives increases the content of some essential amino acids in the pectoral muscles of broilers, which can have a positive effect on their growth, as well as on the quality of meat. Conclusion. The use of feed additives “Kumelakt-1” and “Di-lactocin-Ya” not only improves the nutritional characteristics of meat, making it richer in protein and less in fat, but also significantly enriches it with amino acids and minerals. This demonstrates the potential of these additives for use in the poultry industry to create higher value and healthier products, which may be key to the development of innovative approaches in poultry farming.

This paper takes a multi-perspective approach to understand drivers and barriers of climate action on the neighbourhood level in a selection of European neighbourhoods. The starting point for the analysis is the assumption that actions on the level of citizens to protect the climate are most motivating and promising, when conducted jointly within established social systems like neighbourhoods. The aim of this paper therefore is to identify most relevant factors that are associated with climate actions of individuals on the neighbourhood level. To do so, the paper outlines the multiple perspectives chosen for the analysis of drivers and barriers on the individual, collective, cultural, and socio-structural level. Based on this, a survey was designed to measure these aspects and implemented in nine European neighbourhoods (3 in Austria, 2 in Norway, 2 in Italy, 2 in Finland). The neighbourhoods were partly in rural communities (4) and partly in urban or semi-urban areas (5). In total, 1.084 answers were retained between summer 2022 and summer 2023. The impact of factors from the different perspectives on the self-reported number of implemented climate actions were tested in a structured, regression-based approach. The analyses show that intentions to act both on the individual and collective level impact the number of climate actions implemented by citizens living in the neighbourhood, but individual intentions are more important. In addition, local cultural aspects have an impact on climate action. Individual intentions to act are slightly less important in rural, than in semi/urban neighbourhoods. On the socio-structural level, males and households with younger children report fewer climate actions, whereas larger households in general and people with university degree report more. Intentions to act individually are mostly determined by perceived individual efficacy and attitudes, but also selected cultural and socio-structural factors. Collective intentions to act depend on the social capital in the neighbourhood and social norms, as well as selected socio-structural and cultural factors. Concluding, this paper emphasises that in order to understand, implement (and increase) the climate-related actions of citizens efficient, the individual, collective, cultural and socio-structural factors must be taken into account and that the level of neighbourhoods, where everyday action takes place, is a relevant unit of analysis to do so.
Emerging Insights from a Research-Practice Partnership Approach to Educational Neuroscience
Authors: Toomarian Elizabeth Y , Gosavi Radhika S. , Hasak Lindsey , Bunderson Madison , McCandliss Bruce
Published: April 2024

Advances in the field of Mind, Brain, and Education (MBE) have been limited by a fundamental separation between university-based neuroscience laboratories and school communities, constraining the field’s ability to collaboratively devise research studies germane to child development. This commentary explores the assertion that the persistent obstacles in MBE work may stem from how we structure these partnerships. We examine this premise through a detailed case study of a research-practice partnership that has successfully implemented a range of innovative programmatic elements, including the establishment of specially-trained liaisons, situating a neuroscience lab within a school, and actively involving practitioners and students in research. An analysis of the values that iteratively emerged from this approach may encourage other MBE stakeholders to consider affordances of this model when embarking upon future partnership endeavors.

Introduction: Diffusion tensor imaging is a non-invasive advanced method that provides information on white matter microstructural integrity. Fractional anisotropy and apparent diffusion coefficient have been used to quantify the degree of axonal damage and demyelination. The study aims to assess the role of diffusion tensor parameters in detecting early myelopathic changes and correlate them with clinical findings.
Methods: This cross-sectional prospective study including 60 patients with clinical history of cervical myelopathy was carried out at the Department of Radiology from June 2021 to July 2022. Nurick score was used to assess the severity clinically and diffusion tensor images of the cervical spine were obtained using 3 Tesla MRI. These diffusion tensor values at the level of maximum stenosis were compared with those of the non-stenotic level. A correlation between the diffusion tensor parameters and clinical Nurick score was done.
Results: The fractional anisotropy values were significantly lower (0.51 ± 0.14 vs 0.76 ± 0.47) and apparent diffusion coefficient values were significantly higher (1.20 ± 0.20 vs 1.04 ± 0.12) at the level of maximum stenosis compared with non-stenotic levels. There was a moderate positive and strong negative correlation between the apparent diffusion coefficient and fractional anisotropy values with the Nurick score.
Conclusions: A significant reduction in the fractional anisotropy and an increase in apparent diffusion coefficient values at the level of stenosis was observed in individuals without a high T2 signal within the cord. Thus, these parameters might have a potential role in the early diagnosis of cervical spondylotic myelopathy
