Authors: Kadhim Hadaf Mahdi , Al-Hassani Mithal K. A. , Al-Galebi Ahlam Ali Soghi , Essa Israa M.
Published: November 2024

Background and Aim: Coxiella burnetii is a highly contagious zoonotic bacterial micro-organism. This study aimed to estimate the prevalence of C. burnetii in dogs using serological and molecular methods. Furthermore, a sequencing analysis of C. burnetii dog isolates was conducted. Materials and Methods: A total of 172 dogs, including 93 pet dogs, 21 police dogs, 38 guardian dogs, and 20 stray dogs, were selected. Venous blood was drained from the dogs and examined serologically by indirect enzyme-linked immunosorbent assay (ELISA) and molecularly by polymerase chain reaction (PCR) for C. burnetii. A sequencing analysis of C. burnetii dog isolates was conducted. Results: The overall prevalence of C. burnetii was 16.86%, accounting for 55% in stray dogs, 9.68% in pet dogs, 19.05% in police dogs, and 13.16% in guardian dogs. Strong positive sera were observed in stray dogs (4.84 ± 0.29), whereas weak sera were observed in pet dogs (3.22 ± 0.18). PCR analysis revealed 6.4% positive dogs, accounting for 1.08%, 4.76%, 2.63%, and 40% in pet, police, guardian, and stray dogs, respectively. Phylogenetic tree analysis of local C. burnetii isolates revealed a total rate of similarity and mutations/changes between 95.47% and 100% and 0.059%, respectively. Subsequently, the local isolates were significantly similar to Chinese hedgehog, Iraqi camel, and Colombian human C. burnetii National Center for Biotechnology Information-GenBank isolates. Conclusion: This is the first study on prevalence of C. burnetii in dogs in Iraq. To prevent transmission of C. burnetii to humans, the role of dogs or other domestic and wild animals as sources of infection must be investigated extensively. In addition, the prevalence of C. burnetii in other Iraqi regions should be surveyed using the most sensitive and specific diagnostic assays, such as ELISA and PCR. Keywords: canine zoonotic diseases, Coxiellosis, polymerase chain reaction, Q-fever, sequencing analysis.

Authors: Tayal Swati , Rajagopal K
Published: November 2024

Goal: This study aims to examine the Gamification application of Productivity with Codeathon, which can make employees more engaging at work. The growing presence of Information technology in the industry is increasing the demand for a skilled workforce and further making them productive. Gamification's growing popularity among the industry and academicians is bringing new emerging forms that are beneficial to influence the user experience. However, there are many areas in which gamification has yet to benefit the user experience. The study analyzed the gathered data using confirmatory factor analysis, and the later section detailed the study analysis using a structural equation method.
Design/Methodology/Approach: An online questionnaire gathered data from IT professionals to adopt the exploratory research, where respondents from Pune, India, were the study participants. The statistical approach adopted for this study was factory analysis followed by structural modelling with the help of tools such as IBM SPSS and Amos, which adds to the empirical Gamification contribution.
Results: The study indicated a relationship between Gamification and Productivity among IT employees, where Autonomy was a mediator factor.
Limitations of the investigation: This study primarily focused on the information technology sector among Generation Z and Y, but future research can explore other industries and countries.
Practical Implications: Gamification encourages the participants' motivation level, making them productive at work and bringing sustainability. Companies shall organize gamified events like Codeathon and encourage their employees' participation, and therefore, the human resources team shall include it as part of their annual budget and planning.
Originality/value: There is limited study in the Codeathon, and this research contributes by analyzing the Gamification aspects with Competition and Autonomy. It addresses the organization's emerging need for productivity issues, making it one of the limited studies in the Gamification with Codeathon. As a result, this study addresses the sustainable development goal 8 to bring and attain sustainability for work.

Effects of Bioprosthetic Valve Fracturing on Valve-in-Valve Transcatheter Aortic Valve Implantation Transvalvular Gradients
Authors: Hallak Osama , Fischer Karley , Ailawadi Shaina , Valencia Damian , Yatsynovich Yan , Nazir Raja , Schwartz Brian
Published: November 2024

Background:

Valve-in-valve (ViV) transcatheter aortic valve implantation (TAVI) is quickly becoming a routine and effective means by which to treat degenerated bioprosthetic valves. A known complication of ViV-TAVI is patient-prosthesis mismatch, which substantially affects survival. Bioprosthetic valve fracture is a method by which to reduce the risk of patient-prosthesis mismatch and post–ViV-TAVI transvalvular gradients. This study sought to determine the safety and efficacy of post–ViV-TAVI bioprosthetic valve fracture.

Methods:

Patients with a history of surgical aortic valve replacement undergoing ViV-TAVI bioprosthetic valve fracture (N = 25) at the corresponding institution from 2015 to 2022 were cataloged for a retrospective analysis. The implanted transcatheter valves were Medtronic Evolut R, Evolut PRO, and Evolut PRO+. Gradients were assessed before and after implantation and after fracturing using transthoracic echocardiogram.

Results:

The mean left ventricular ejection fraction of patients who underwent fracturing was 55.04%. The average (SD) peak and mean (SD) transvalvular gradients before the intervention were 68.17 (19.09) mm Hg and 38.98 (14.37) mm Hg, respectively. After ViV-TAVI, the same gradients were reduced to 27.25 (12.27) mm Hg and 15.63 (6.47) mm Hg, respectively. After bioprosthetic valve fracture, the gradients further decreased to 17.59 (7.93) mm Hg and 8.860 (3.334) mm Hg, respectively. The average reduction in peak gradient associated with fracturing was 12.07 mm Hg (95% CI, 5.73-18.41 mm Hg; P = .001). The average reduction in mean gradient associated with valve fracturing was 6.97 mm Hg (95% CI, 3.99-9.74 mm Hg; P < .001).

Conclusion:

Bioprosthetic valve fracture is a viable option for reducing residual transvalvular gradients after ViV-TAVI and should be considered in patients with elevated gradients (>20 mm Hg) or with concern for patient-prosthesis mismatch in patients who have an unacceptable risk for a redo sternotomy and surgical aortic valve replacement.
A Comprehensive Review of Atrial Infarction
Authors: Grosso Domenic , Dickman Jacob , Valencia Damian
Published: November 2024

Atrial infarction is often undiagnosed in patients with underlying ischemic heart disease and is identified only later, upon autopsy. One of the main challenges in diagnosing the condition is its localization within the affected atria. Treatment of atrial infarction focuses on acute reperfusion therapy, long-term management of cardiovascular disease risk factors, consideration of antiarrhythmia medications, and anticoagulation therapy. This review covers the anatomy of the atrial vasculature, complications associated with atrial infarction, diagnostic criteria for use of electrocardiography and other imaging modalities, and overall prognosis and management.
Text Sets: A Comprehensive Analysis of the Literature
Authors: Freeman Greta G. , Hardin Brooke L.
Published: November 2024

Text sets (also referred to as linked text sets, multimodal texts, thematic texts, multi texts, focus units, reading across texts, and paired readings or sets) are utilized in classrooms to promote reading, learning, and understanding of multiple perspectives. There has not been an analysis of studies on text sets or on the wide-ranging effects of text sets. The purpose of this review was to conduct a comprehensive analysis of text sets and their effects on student achievement. Several writings describing text sets and their development, as well as experimental studies reporting on the effects of text sets, were identified through a thorough database search. Findings from this review reveal that there are over 100 peer-reviewed journal articles, books, book chapters and theses related to text sets. There is evidence to support the use of text sets for helping preschool to college age students gain multiple perspectives on a topic, become highly engaged and motivated, and improve critical thinking, comprehension and writing skills.
Insider Knowledge, Outsider Practice: The Disruptive Liberatory Potential of Skateboarding in US Higher Education
Authors: Davidson Eric M.
Published: November 2024

This conceptual paper articulates how the unique social, experiential, and navigational perspectives of college skateboarders contribute to their potential as changemakers in higher education. Drawing from the theory of campus ecology and multidisciplinary body of skateboarding scholarly literature, this paper applies the unique navigational and analytical lenses of skate culture to render visible oppressive institutional conditions that are currently absent from educational scholarship. In order to accomplish this application, I conduct an extensive search for literature, and begin the writing by contextualizing the macro- and micro-systemic elements of the U.S. tertiary system and emplacing skateboarding within them. Then, I use skate scholarship to argue that skateboarding provides new critical perspectives on the philosophies of public space, policing, and social deterrence that manifest in university spaces. Additionally, this work explores campus skaters’ resistance to systemic challenges such as racism, cisheteropatriarchy, and neoliberal capitalism. I conclude by offering future directions for both theoretical and empirical research that employ skateboarding as a lens through which to examine U.S. higher education.

Authors: Gilpin Staci , Rabenn McKenzie
Published: November 2024

This study delves into the experiences of two female online doctoral students who navigate the complexities of motherhood and rural living, aiming to enhance understanding and improve persistence rates in their academic pursuits. By employing a narrative inquiry approach, the research highlights the transformative power of narratives and storytelling in gaining insights into the lives of these students. The findings illuminate systemic barriers that limit their access to research opportunities and collaborative spaces. The study underscores the necessity of creating inclusive environments, fostering effective virtual mentorship, and offering comprehensive support for health and well-being. Through these targeted strategies, educational institutions can play a pivotal role in fostering a more equitable and supportive landscape for all doctoral students, particularly those identifying as female. Such efforts are instrumental in not only enhancing their academic success but also in ensuring their personal well-being and growth.
Editorial Introduction: In the Face of Urgency, Making Space for the Emerging
Authors: Desimoni Victoria , Stone Courtney , Kim Minji , Chaomuangkhong Tipsuda
Published: November 2024

This Editorial Introduction reflects on the challenges and complexities facing education amidst political, social, and environmental crises, emphasizing the need to engage with emerging solutions rather than being paralyzed by urgency. In the context of the current multicrisis, it envisions CIE as a beacon of hope—a space to step back and recognize emerging efforts. We call for slowing down, not as a passive act but as an active effort to nurture the possibilities arising from these crises. The introduction highlights the five articles in this issue, featuring scholars addressing real problems in education, exploring alternatives, and uncovering unexpected possibilities. From teaching white nationalism in the Trump era to navigating the challenges faced by women in online doctoral programs, or examining skateboarding as a counterculture in higher education, these studies illuminate the layered realities of education and society.
Looking Beyond the Canon: Localized and Globalized Perspectives in Art History Pedagogy
Authors: Chandra Aditi , Cempellin Leda , Chiem Kristen , Dardashti Abigail Lapin , Dalal Radha J. , Kenney Ellen , Kamran Sadia Pasha , Murayama Nina , Elkins James P.
Published: November 2024

Our pedagogical choices make art history classrooms political spaces of cultural production. Through a global exchange of ideas we consider questions of imbalance between western and non-Western materials and differing art history pedagogies in introductory courses and reveal teaching methods shaped by varied local contexts. Kristen L. Chiem suggests re-routing students to the fundamentals of art historical inquiry rather than to a specific time or region. Abigail L. Dardashti's essay re-configures the global art history course by focusing on artworks that defy the neat West and non-West categories. Radha J. Dalal discusses a curriculum that includes a series of courses on Islamic arts in a global context, which highlight shared visual cultures as an alternative to the traditional perspective. Ellen Kenney discusses the complexities of teaching Islamic art history in a city where the art the author teaches is located. Sadia Pasha Kamran explores the post-1970s Islamization of Pakistan's art history curriculum and stresses the necessity of educators to foreground the syncretic nature of Pakistan's past and the diversity within Islamic art. Nina Murayama presents methods of teaching the global survey to Japanese students within a monocultural setting and stresses that the importance of local narratives in world art courses. There is potential in the interdisciplinary nature of art history and specifically in the way we approach introductory courses that can enable students to become global citizens. To be globally competent is to understand the interconnectedness of our increasingly complex world and to appreciate its diversity  precisely the skills that global art history courses, that challenge the canon, can provide. The purpose of these introductory courses, then, is to cultivate students' empathy, so that they can become aware of their assumptions and welcome challenge rather than feeling threatened by difference.
Why World Art is Urgent Now: Rethinking the Introductory Survey in a Seminar Format
Authors: Bender Gretchen Holtzapple
Published: November 2024

Ultimately, what can and should an introductory course in the history of art do? What difference can it make and what work can it perform? To fully contemplate these questions and radically rethink the standard large-lecture survey, in an experiment, it was taught as an advanced seminar to both majors and general education non-majors, with "global understanding" privileged over extensive content knowledge. The classroom environment moved from the authoritative stance imposed by a lecture format to a space for speaking and listening that was collaborative and exploratory, nurturing curiosity and critical thinking not just about disciplinary knowledge and methods, but also alterity itself. This essay considers both the theoretical impetus for this project (planetary thinking) and details the practical ways in which class activities and assignments were designed to achieve learning objectives. Focusing on the conceptual scaffold for the course  careful and mindful thinking about the art encounter, the meaning of conversation, and the value of not knowing  I will argue that in an age of deep and entrenched misunderstanding, stark polarization, and escalating tension and conflict, the world art course can and must compel students to think about being human.
Bringing Students into the Picture: Teaching with Tableaux Vivants
Authors: Foutch Ellery E.
Published: November 2024

This article explores a recent experiment in implementing tableaux vivants as a college-level art history assignment, in which students researched works of art and also assumed the pose, posture, and attributes of the work; students were also invited to reconceptualize and think transformatively about these historical works. Drawing upon the principles of Universal Design for Learning, the assignment offers an impetus for close looking, research, critical thinking, interpretation and creativity, and an engagement in metacognitive and embodied experiences, as will be demonstrated by the resulting assignments and students' written self-reflections. While the assignment was originally designed for a course focused on American culture prior to 1830, this approach could apply to a broad chronological and geographical range to encompass nearly any figurative art.
Creativity-Integrated Art History: A pedagogical framework
Authors: Meloche Alysha , Katz-Buonincontro Jen
Published: November 2024

Art history offers a unique opportunity for students to encounter real, historical examples of the creative process in action. By showing examples of the complex process through which artwork is created, art history classes can provide emulative examples for the next generation of innovative designers, artists, historians, educators, and creative thinkers. Art history has a tradition of teaching Big-C creativity principles by highlighting creative products and individuals. Therefore, the art object is emphasized at the expense of unpacking the process and everyday, or mini-c, creativity of the work. At a time when the field of Art History is beginning to ask itself what it really wants students to gain from their classes, creativity should be one of those skills. The purpose of this paper is to present a pedagogical framework for reconsidering the way art history material is presented to students in a way that promotes personal creativity growth. The suggestions in this article take advantage of strengths that are already present in the field of art history, while also pointing out new means of bridging the gap between Big-C and mini-c creativity by incorporating principles of design thinking. This article includes a sample lesson of what Creativity-Integrated Art History (Cr-IAH) can look like.
A Didactic Teaching and Learning Project in Art Market Research. Researching and Publishing the History of Commercial Art Dealing
Authors: Oberste-Hetbleck Nadine
Published: November 2024

In addition to research, one of the main tasks of art historians is the authoring of academically and stylistically sound texts in differing genres. This case study of the research and publishing project Zur Geschichte des Dsseldorfer Kunsthandels (A History of Commercial Art Dealing in Dsseldorf) will demonstrate how research and writing can be integrated into teaching. The project involved supervised work with source materials, data visualization, semi-structured interviews (oral history), a supplementary writing workshop, as well as detailed feedback from a writing instructor, the teacher, and fellow participants in the seminar. In addition, the high practical relevance of the project (collaborations with galleries and art dealers) increased the participants' later employability. This paper presents both the project's general and specific study objectives (acquisition of methodologies, social and subject-specific skills), its structure and development, discusses its challenges, and critically reappraises the process. It concludes by considering the ways in which writing could be better incorporated into the teaching of Art History at university.
Addressing Visual Literacy in the Survey: Balancing Transdisciplinary Competencies and Course Content
Authors: Archino Sarah
Published: November 2024

Inspired by partnerships between medical schools and museums that produce measurable outcomes in the frequency and sophistication of diagnostic observations through limited art history-based interventions, this paper documents the re-orientation of a traditional art history survey course to explicitly address foundational visual literacy skills. This Spring 2019 pilot implemented a series of exercises and assessments designed to directly target transdisciplinary components of visual literacy and to highlight these competencies through student discussion and reflection with minimal disruption. This study employed content analysis and qualitative coding of pre- and post-tests to capture and characterize the number and types of observations made on descriptive, timed writings. This data was combined with participant reflections to assess whether students enhanced their skills of observation and description. The results suggest that minimally-invasive, low-stakes assignments, coupled with reflection exercises, produced increases in both the quantity and quality of student observations; students also demonstrated more awareness of their audience, adjusting the information as appropriate to the specific task and recognized connections between this practice and other fields of study. This suggests that art history could better communicate the transdisciplinary skills of visual literacy and promote their development within the survey course without a radical course redesign.
Assessing Undergraduate Fashion History Research via Content Analysis
Authors: De Young Justine
Published: November 2024

Undergraduate art history students are often asked to write research essays on specific artworks, but that research is rarely considered publishable or reliable. This article analyzes undergraduate student essays on fashion history to determine whether the research produced can be considered reliable according to generally accepted art historical standards. It employs content analysis to make those determinations in addition to the instructor's own standards and those governing the Fashion History Timeline, an open-access hub of fashion history research. The article investigates the impact of a multi-stage writing and revision process on student writing outcomes and on student grades. Finally, it addresses the benefits of quantifying student research via content analysis for improving both teaching and student outcomes.
Making American Art an Engaging General Education Course
Authors: Verplanck Anne
Published: November 2024

Humanities courses are often populated with students who primarily take these offerings to meet General Education requirements. American art classes can provide opportunities for students to think analytically and consider what is included as well as what is omitted in visual and textual formats. This article provides examples and the pedagogical rationales for a range of in-class and out-of-class activities that enable active learning, critical thinking, creativity, and kinesthetic engagement. Creating on-line resources to replace a textbook, taking field trips on or adjacent to campus, and exhibition critique and label-writing activities can be easily adapted to campus- and online-learning settings at little or no cost. These approaches address some of the challenges that the academy, like the museum, face: who, how, and what one learns; how to balance the canon with works of art, topics, issues, and ideas related to those who have traditionally not been represented; and how to equalize access to institutions.
Building Pedagogy: Studying Architecture and Preservation in American Art and Architectural History
Authors: Kocyba Kate
Published: November 2024

In this essay I discuss how my course attempts to broaden the definition of the American architectural canon by bringing in the discipline of preservation and, by extension the discussion of vernacular architecture. Throughout the course students are given assignments meant to engage with all levels of Bloom's Taxonomy. By highlighting specific assignments such as a National Register of Historic Nomination Form, and a student led class discussion on Colonial Williamsburg I will show how students engage with the upper levels of Bloom's Taxonomy. At the same time this essay demonstrates how a course on architecture of the United States allows this material to become more inclusive, dynamic and comprehensible to a diverse student population. Ultimately, a course on American architectural history adds another perspective to the discipline of art history of the United States.
Food and Cultural Politics: A Culinary Lens into Teaching American Art and Culture
Authors: Terrono Evie
Published: November 2024

Seeking to challenge students to think deeply and critically about American art and material culture and their broad socio-cultural implications in the past and present, I developed in 2017 a course that explored the interpretation of foodstuff and American foodways in American art, prints and commercial advertising, and material culture. This article analyzes the pedagogical objectives of the course in its integration of a multi-modal learning approach that reinforced connections between learning, experiencing, and critical interpretation. Capitalizing on the emergence of scholarship in food studies in American art and through other cross-disciplinary readings students analyzed food symbolism, racial and economic stereotyping, depictions of production and labor, the provision and circulation of food stuff, excess or deprivation at various historical moments, and issues of gender, race and social status, as related to food production and consumption. The course privileged depth over coverage, immersed students in interrogations of complex and often fraught ideas, engaged them in object-based learning and required that they apply developed skills in disciplinary research. In its integration of multi-faceted reflective, interactive, embodied experiential learning and a social justice component, a cookbook that included students' research that was sold as a fundraiser, the course expanded beyond the classroom and connected historical and visual literacy with current ideological concerns.
African-American Art History: Reflections on Expanding Pedagogy in 21st Century Liberal Arts Contexts
Authors: Bullington Judy
Published: November 2024

An undergraduate seminar on African-American Art History was used as a case study to explore how critical perception skills may be developed through the implementation of interactive exercises. Active looking, creative connections, and experiential learning were among the pedagogical approaches embedded into the content. The goal was not to write a revisionist history of the subject matter but to utilize existing resources to reconfigure how the historical narrative may be discussed and articulated through diverse vantage points. Examples of assignments are provided as models and SoTL thought experiments. Reflections upon the definition of critical perception' versus critical thinking' and visual thinking' are also included in the article. Consideration is given to ways of using critical perception to cultivate a sense of empathy and flexible reasoning. Critical perception is regarded as a cornerstone of art historical practice presenting educators with an opportunity to teach a skill set which could be leveraged to raise awareness about the relevancy of a discipline that is all too often relegated to the edge environment of academic curricula.
Decolonizing the Classroom: Native American Art History, the Voice of Indigenous Students, and Community-Oriented Teaching
Authors: Palm Puchner Nancy
Published: November 2024

As a professor at the University of North Carolina at Pembroke, I seek to understand the role of Native students in the teaching of Native art history, while not losing sight of the potential dangers of asking minority students to somehow represent or speak for an entire race. Like museums, the classroom is a historically colonizing space, but also an important site for revolution and transformation. In my course on North American Indian Art, in which roughly two-thirds of the students identify as Native, I strive to expose students to a range of Indigenous arts and crafts and the theoretical and spiritual contexts that surround them. My goals while teaching this material are as follows: 1) give a voice to Native students who are functioning in a university structure that, as part of a larger bureaucratic system, has served to historically oppress them as a people; 2) both serve and absorb into my classroom the Native community in which I teach; and 3) remain teachable myself. None of these goals would be attainable without the contributions of the Native students in my class. This essay explores their role and mine within the revisionist, decolonizing process that has taken shape within the study and display of Native American art and culture in the United States.
Art History, Open Educational Resources (OERs), and Social Justice-Oriented Pedagogy: Adaptations to Introductory World Art History Survey Courses
Authors: Ishii Sara
Published: November 2024

This essay considers the social justice benefits of adopting OERs in an introductory art history survey course. Following the events of the COVID-19 pandemic, instructors have needed to reevaluate pedagogical approaches and teaching materials. Coupled with this present need to foster accessible and flexible courses, for decades art historians have observed the overrepresentation of white Western art and subsequent marginalization of global art in survey textbooks. Centering the need for a social justice-oriented pedagogy that recognizes global contributions to art history, I first reflect on the potential to adapt open educational resources (OERs) to disrupt status quo narratives that privilege Western art. Second, I discuss my adaptation of the open access textbook Boundless Art History by Lumen Learning in which I reformat the material to examine artwork across the globe in timeframe units. Finally, I conclude by reviewing student responses to a Google Forms survey about their experiences with OERs and positing additional benefits and further developments for open access course materials within introductory art history survey courses.
Portals to Learning: Threshold Concepts in Art History Teaching and Learning
Authors: Reymond Rhonda L.
Published: November 2024

Threshold concepts are conceived of as portals to learning that open previously inaccessible ways of thinking. They encompass specific ideas within a discipline that must be mastered before the learner can progress. The process of identifying threshold concepts can reveal hidden or unacknowledged fundamental disciplinary beliefs and epistemology. Integrating a threshold concepts framework into the scholarship of teaching and learning in art history (SoTL-AH) can help faculty diagnose and anticipate when students are likely to encounter troublesome knowledge within an art history course. Distinguishing these thresholds can aid instructors in designing courses that prepare for specific stages that present conceptual or affective difficulty and turn those into transformative experiences that promote reconstituted and integrated knowledge. Threshold concepts can also be applied more broadly to benefit curriculum design, assessment, and the profession. This paper explains threshold concepts and bottlenecks, describes the benefits of using threshold concepts, identifies potential limitations in utilizing them in the design of teaching strategies, and proposes some preliminary threshold concepts in art history.
River Flow Analysis using HEC-HMS and Assessing the Impact of Climate Change on Hydropower Generation by MODSIM in the Koka Reservoir of Ethiopia
Authors:   Arba Minch University, Ayalew Abebe Temesgen , Lohani Tarun Kumar ,   Arba Minch University, Meskr Yordanos Mekuriaw ,   Arba Minch University
Published: November 2024

Climate change results in precipitation variation in rivers and other water bodies, resulting in a decline in reservoir inflow and hydropower generation. This study is aimed at the assessment of climate change under different environments for hydropower generation and optimal reservoir operation using updated representative pathways (RCPs) in the Koka reservoir of Ethiopia. The power transformation function and variance scaling techniques of numerous meteorological data were adopted for bias correction. The simulation of flow was performed using HEC-HMS and the generation of hydropower from the reservoir was estimated using MODSIM 8.1 under different climatic scenarios. NSE and R2 (90.72 and 0.70) were calculated based on the model performance features for calibration and validation, respectively. There was a remarkable anomaly in the pattern of precipitation and temperature based on the projection of future climate scenarios. This change ultimately affects the power generation with an apprehension of reduction of 0.54% and 0.72% in the near term (2021–2050) and long term (2051–2080) under RCP4.5. Similarly, the mean generation of energy will reduce by 1.04% in the short term and 1.32% in the long-term for RCP8.5. This shows that the reduction is more prevalent in RCP8.5 in comparison to RCP4.5. Simply, it can be concluded that if strict measures are not timely initiated, there will be an acute power shortage. The research findings warn the concerned bodies to take timely measures to reduce recurring sediment deposits and ensure future hydropower output.

Direct somatic embryogenesis on Coffea arabica L. explants previously subjected to water restriction
Authors: Almeida Julieta Andrea Silva de , Neofiti Wilielle Cristina Freitas , Marchiori Paulo Eduardo Ribeiro , Giomo Gerson Silva
Published: November 2024

Somatic embryogenesis can occur either directly or indirectly. However, Coffea arabica genotypes respond inefficiently to direct somatic embryogenesis. In this way, explants of this species form small embryogenic structures (pre-embryogenic masses) and a few somatic embryos. Studies have shown that the intensity of the osmotic potential can either favor or hinder the somatic embryogenesis response in different species. Plant tissue subjected to water restriction presents a reduction in osmotic potential. Therefore, this study aimed to evaluate the direct somatic embryogenesis response of leaf explants from four genotypes of C. arabica, which were previously subjected to 0, 1, 2, 3, 4 and 8 days of water restriction. At time 0, the explants had an average humidity of 70 %, which decreased to approximately 40 % after 8 days of water restriction. Somatic embryo formation occurred in explants subjected to up to 3 days of water restriction and there was no response in those with 4 and 8 days without hydration. Explants with low intensity osmotic potential of up to -0.8 MPa formed somatic embryos, whereas this response was reduced or inhibited in those with a more negative osmotic potential. However, explants with an osmotic potential equal to or less than -1.6 MPa formed larger embryogenic structures, which is desirable as they also give rise to somatic embryos. Thus, the direct somatic embryogenesis response of C. arabica is influenced by the intensity of the osmotic potential in the explant tissue.

Pulmonary arteriovenous malformations (PAVMs) universally develop in patients with single ventricle congenital heart disease. Single ventricle PAVMs have been recognized for over 50 years but remain poorly understood. To improve our understanding, we developed a surgical rat model of Glenn circulation and characterized PAVM physiology over multiple time points. We performed a left thoracotomy and end‐to‐end anastomosis of the left superior vena cava to the left pulmonary artery (unilateral Glenn), or sham surgical control. To assess PAVM physiology, we quantified intrapulmonary shunting using two independent methods (bubble echocardiography and fluorescent microsphere injection). Additionally, we performed arterial blood gas measurements to assess oxygenation and plethysmography to assess ventilation. We identified pathologic intrapulmonary shunting by bubble echocardiography as early as 2 weeks post‐Glenn, and shunting continued at 2‐ and 6‐months post‐Glenn. Shunting also progressed over time, demonstrated by increased shunting of 10 μm microspheres at 6 months. Shunting was accompanied by mildly decreased oxygenation but no differences in ventilation. Our surgical animal model of unilateral Glenn circulation recreates the clinical condition of single ventricle PAVMs with early and progressive intrapulmonary shunting. This model is poised to characterize single ventricle PAVM pathophysiology and lead to mechanistic and therapeutic discovery.

Authors: Бузальская Елена Валериановна
Published: November 2024

Целью статьи является лингвокогнитивное описание речевого жанра «загадка» и определение его основных вариантов. В рамках теории речевых жанров «загадка» является малоформатным, простым, вторичным косвенным речевым жанром, изначально связанным с мифологической картиной мира. Прагмалингвистически речевой жанр «загадка» ориентирован на речевую стратегию загадывания (кодирования заранее известного спрашивающему объекта), которая реализуется при помощи деиктических речевых тактик. В результате предпринятого анализа речевого жанра фольклорной загадки выделено 6 основных лингвокогнитивных структур (12 вариантов в поле вариативности модели жанра) на основании следующих групп характеристик: (1) концептуально-когнитивных характеристик (структурной принадлежности к гештальту, фрейму или сценарию); (2) типа речевой тактики (поддержки стереотипа или его разрушения); (3) появления одушевленности в результате метафорического переноса. Внутри данных групп автор выделяет подгруппы, которые связаны с полнотой описания загадываемого объекта.

The objective of this article is to study the compartmental modeling approach for the prediction of unreported cases of coronavirus disease 2019 by considering six compartments. Our model is described by a system of six ordinary differential equations with initial conditions. The basic properties of solution of the model are established. The model is shown to have two equilibrium points, i.e., the disease-free and endemic equilibrium points. The basic reproduction number

Drying kinetics, energy utilization (EU) and shrinkage level of avocado pear pulp during drying were investigated and modeled to determine the condition that enhances the quality of the dried product. Drying was carried out using a microwave assisted dryer with data lodger. The system was set at a constant power of 200 W, air velocity of 1.4 m/s, and temperatures of 50, 60 and 70 °C with pulp thickness being 5 mm. Fifteen thin-layer drying models, five non-linear shrinkage models and ANN methods were tested for describing the drying behaviour of avocado pulp using statistical parameters. The results revealed that drying took place in the falling rate period with the above temperatures reducing the moisture content of the pulp from 64.12 to 2.16 % wet basis within 15,360, 11,520 and 5,130 s, respectively. The drying rate and effective diffusivity increased with increase in temperature and ranged from 6.05 × 10−3 to 1.70 × 10−2 kg/kgs and 3.11 to 9.34 × 10−9 m2/s, respectively. The activation energy of the pulp was 50.34 kJ/mol. Among the drying models tested, Page and Aghashilo models provided the best statistical parameters for describing the drying behaviour of the pulp, while ANN demonstrated great ability to predict MR and SR more accurately with high and low R2 and RMSE. A non-linear shrinkage model developed also had the best fit qualities for describing the shrinkage behaviour of the pulp. The energy utilized (EU), specific energy utilized (S

), heat transfer coefficient (h

tc

) and mass transfer coefficient (M

tc

) of the pulp ranged from 7.36 to 3.19 kWh, 11.21 to 5.76 × 10−2 Wh/kg, 0.1054 to 7.98 × 10−7 W/mK and 2.06 to 4.28 × 10−6 m/s respectively and were statistically (5 %) influenced by temperature. The EU model developed had the best description behaviour of the energy relationship with other factors, having high R2 and low RMSE and SSE values.
Cartography of Cultural Practices and Promoting Creative Policies for an Educating City

Published: November 2024

This article results from a knowledge transfer report commissioned by the Culture Area of the A Coruña City Council in Galicia (Spain), a city with an average population of 250,000 inhabitants. The report’s goal was to map all the cultural actions happening in the city. Due to their variety, dispersion, and multiplicity, the local government’s culture department required a comprehensive catalogue of these practices. The initial challenge was to collect and structure the information to create a visual atlas that would allow for the mapping of these activities, identifying potentialities, shortcomings, and weaknesses to establish future cultural action lines. As a result of investigative and fieldwork, it was decided to document the actions carried out by both public and private institutions, whether conducted by the City Council’s culture department, funded externally, or independent. This information was analysed to draw conclusions for planning the city’s cultural future.

Published: November 2024

Objectives

To investigate longitudinal trends in the incidence, preventability, and causes of DAEs (diagnostic adverse events) between 2008 and 2019 and compare DAEs to other AE (adverse event) types.

Methods

This study investigated longitudinal trends of DAEs using combined data from four large Dutch AE record review studies. The original four AE studies included 100–150 randomly selected records of deceased patients from around 20 hospitals in each study, resulting in a total of 10,943 patient records. Nurse reviewers indicated cases with potential AEs using a list of triggers. Subsequently, experienced physician reviewers systematically judged the occurrence of AEs, the clinical process in which these AEs occurred, and the preventability and causes.

Results

The incidences of DAEs, potentially preventable DAEs and potentially preventable DAE-related deaths initially declined between 2008 and 2012 (2.3 vs. 1.2; OR=0.52, 95 % CI: 0.32 to 0.83), after which they stabilized up to 2019. These trends were largely the same for other AE types, although compared to DAEs, the incidence of other AE types increased between 2016 (DAE: 1.0, other AE types: 8.5) and 2019 (DAE: 0.8, other AE types: 13.0; rate ratio=1.88, 95 % CI: 1.12 to 2.13). Furthermore, DAEs were more preventable (p<0.001) and were associated with more potentially preventable deaths (p=0.016) than other AE types. In addition, DAEs had more and different underlying causes than other AE types (p<0.001). The DAE causes remained stable over time, except for patient-related factors, which increased between 2016 and 2019 (29.5 and 58.6 % respectively, OR=3.40, 95 % CI: 1.20 to 9.66).

Conclusions

After initial improvements of DAE incidences in 2012, no further improvement was observed in Dutch hospitals in the last decade. Similar trends were observed for other AEs. The high rate of preventability of DAEs suggest a high potential for improvement, that should be further investigated.
