Background
PCV2 infection in piglets reduces growth performance and increases mortality, causing serious economic losses. Guifu decoction (GFD) is a restorative Chinese medical formulation containing several individual herbs with antiviral and anti-inflammatory effects. Animal studies have revealed that GFD is protective in pigs infected with porcine circovirus (PCV2). However, the mechanism is still unclear. In this study, we aimed to evaluate the effects of GFD against PCV2 infection in mice and determine its mechanism of action, focusing on the PPAR-γ/NF-κB signaling pathway.
Methods
The therapeutic effect of GFD on PCV2-infected mice was assessed in terms of its prevention of ileum and lung pathology. RNA sequencing (RNA-seq) was used to determine pulmonary transcriptome profiles under various conditions. 16S rRNA sequencing was carried out to verify the role of GFD in the regulation of intestinal microbiota.
Results
We found that GFD treatment reduced the PCV2-induced inflammatory response and damage to the ileum. GFD strengthened the intestinal mucosal barrier and increased the expression of MUC2 mRNA. PCV2 infection reduced the diversity of intestinal microbiota, but GFD treatment increased the relative abundance of lactobacilli and decreased potentially pathogenic bacteria such as Mycoplasma. KEGG enrichment analysis of differentially-expressed genes showed activation of the PPAR-γ/NF-κB pathways; specifically, the expression of Olr1 and Scd1 genes was significantly up-regulated, while Acox2, Plin1, and Cyp4a12b genes were down-regulated. GFD treatment increased PPAR-γ protein and decreased levels of IκBα and P-IκBα, p65 and P-p65 in the PCV2-infected mouse model.
Conclusions
Taken together, these results indicate that GFD enhanced intestinal integrity and barrier function by altering intestinal microbiota composition, which subsequently alleviated intestinal injury and improved health. It also reduced the systemic response to the virus and subsequent inflammation through the PPAR-γ/NF-κB pathway. Our data provide novel insights into the potential pathophysiology of PCV2-induced disease in piglets and enhance our understanding of the role of the gut microbiota in the mechanism. Deducing how the GFD formulation protects against PCV2 could lead the way to the development of novel effective therapies to combat intestinal diseases and improve the health and growth performance of pigs.
NetPSig: Computationally guided neutrophil extracellular trap-associated signature significantly predicts the prognosis and therapeutic response in breast cancer

Published: March 2023

Background: Considerable evidence suggests that neutrophil extracellular traps (NETs) are involved in cancer development and metastasis dissemination. Equally important, the yet to be defined role of NETs in resistance to cancer therapies.
Results: Herein, we investigated the expression alterations and genetic variations (mutations, SNPs) in NETs-associated genes and related them to the clinical outcomes in breast cancer (BC) patients. To strengthen our analysis, we established a novel prognostic signature (named as, NetPSig) and confirmed its robust performance using several independent BC cohorts and publicly available BC gene-based signatures. Our analysis clearly demonstrated that: 1) expression and genetic variation of NETs-associated genes significantly contribute to the prognosis of BC; 2) NetPSig complements BC-related clinically valuable variables such as age, PAM50 and tumor stage; 3) the biological disparities in high- and low-risk groups identified by NetPSig confer prognostic values (p-value ≤ 0.01), in particular, the high-risk group showed worse prognosis with enrichment of P53mutations, 4) NetPSig performed positively in predicting the therapeutic response and identified five potential drugs (AZD7762, Bosutinib, DMOG, Docetaxel and Sunitinib) for the treatment of BC patients with lower risk score category.
Conclusion: In summary, a novel prognostic signature (NetPSig) presented in this study provides more robust and better predictive performance compared to the existing BC gene-based signatures. Besides, we support the notion that NET-associated genes represent an opportunity to further improve the efficacy of cancer therapy.

Published: March 2023

Carbyne, an elusive sp-hybridized linear carbon allotrope, has fascinated chemists and physicists for decades. Due to its high chemical reactivity and extreme instability, carbyne was much less explored in contrast to the sp2-hybridized carbon allotropes such as graphene. Herein, we report the on-surface synthesis of a polyynic carbon chain with ~40 alkyne units (80 carbon atoms), exhibiting the longest polyyne synthesized and characterized to date as a model for carbyne. The polyynic structure of carbon chains with alternating triple and single bonds is unambiguously revealed by bond-resolved atomic force microscopy, and the decoupled polyynic carbon chain exhibits a band gap of 3.67 eV measured by scanning tunneling spectroscopy. Our results provide a feasible route for the synthesis of long and stable polyynic carbon chains, leading a way to the final preparation of carbyne.
Tumor growth ameliorates cardiac dysfunction and dampens fibrosis in a mouse model for Duchenne Muscular Dystrophy

Published: March 2023

Heart failure and cancer are known to share common risk factors. Nevertheless, until recently, these two were considered separate diseases. Nevertheless, it appears that heart failure and cancer are more connected than initially anticipated. The interplay between heart failure and cancer represents a double-edged sword. While Cardiac remodeling promotes cancer progression, tumor growth suppresses cardiac hypertrophy and reduces fibrosis deposition. Whether these two opposing interactions are connected is currently unknown. In addition, the experimental setup used was unable to distinguish whether tumor growth suppresses de novo fibrosis synthesis or is capable of dissolving existing fibrosis as well. Here we studied a clinically relevant human disease, Duchenne Muscular Dystrophy (DMD), using MDX mouse as a model for a fibrotic disease in multiple organs. Duchenne patients suffer from fibrosis of the skeletal, cardiac, and diaphragm muscles leading to cardiomyopathy, and respiratory failure with no cure. To study the mutual interaction between heart failure and cancer, we implanted murine cancer cells in MDX mice and monitored tumor growth, cardiac function, and fibrosis. Surprisingly, cardiac dysfunction failed to promote cancer progression in MDX mice. In contrast, MDX tumor-bearing mice displayed reduced fibrosis in the lungs, heart and diaphragm muscles resulting in an improvement of cardiac contractile function. The latter is at least partially mediated via macrophage polarization towards M2 in the heart and diaphragm muscles. Collectively, our data support the notion that tumor promotion due to heart failure is an independent of cardiac dysfunction amelioration by tumor growth. Additionally, these results suggest that the reduced overall fibrosis in tumor-bearing MDX mice represents suppression of de novo fibrosis deposition as well as dissolving existing fibrosis in the heart and diaphragm muscles. Harnessing tumor paradigms may provide novel therapeutic strategies for DMD patients, human fibrotic diseases, and cardiac dysfunction.
Blockchain and IoT-Powered Carbon Credit Exchange for Achieving Pollution Reduction Goals
Authors: B Sai Shibu N
Published: March 2023

Carbon dioxide (CO2) emissions primarily contribute to global warming and climate change. The immediate source of CO2 emissions is burning fossil fuels like petrol, diesel, natural gas and coal, accounting for 78% of total emissions. CO2 emissions have risen since the late 1800s, reaching a record high of 33.1 billion tons in 2019. The paper proposes a Blockchain and IoT-based framework to track and trade carbon credits, aiming to reduce carbon dioxide emissions and mitigate their impact on global warming and climate change. We consider electrical energy as one use case for carbon emission and credit trading. The framework will monitor the energy usage of each entity, recording real time carbon emissions in a tamperproof blockchain ledger. Each entity will receive carbon credits based on the recorded emissions, which can then be traded on a blockchain exchange. This will enable entities with higher emissions to offset their emissions by purchasing credits from entities with lower emissions. The blockchain ledger ensures the authenticity and transparency of the carbon emissions data, promoting a secure and efficient solution for reducing carbon emissions. The paper also outlines a reward and penalty mechanism for consumers, encouraging them to reduce their carbon footprint and contribute to a more sustainable future. The paper discusses the blockchain and IoT-based carbon credit exchange architecture, including algorithms for estimating energy consumption, carbon emissions, reward, and penalty. The paper concludes with a proof of concept implementation using the Ethereum platform and a performance evaluation of the algorithms. The paper proposes a comprehensive solution for reducing carbon emissions and mitigating their environmental impact, leveraging the strengths of blockchain and IoT technologies.
An Efficient Sampling Framework for Graph Convolutional Network Training
Authors: Gacem Abderaouf , Seba Hamida , Haddad Mohammed
Published: March 2023

Graph Convolutional Networks (GCNs) are a subcategory of neural networks that can take a graph as input. They have been solicited lately due to their success and the ubiquity of data that can be represented as graphs. However, handling large graphs has been one of the main challenges for GCNs, along with the oversmoothing problem that can be caused by the depth or the large receptive field of GCNs. A lot of work has been done to address this problem with different approaches. A promising one is the consideration of the minibatch training paradigm and extending it to graph structured data by extracting subgraphs to be used as batches.
Unlike the entries of a dataset of images that are independent from one another, the essence of a graph is its topology structure, hence the dependency between its nodes. Thus, the strategy of selecting subgraphs to form minibatches is a difficult task with a huge impact on the results of the training process.
In this work, we propose a general framework for generating minibatches in an effective way that ensures a minimum loss in node interdependence information, preserves the original graph properties, and diversifies the samples for the GCN to better generalize afterwards.
We test our training process on real world datasets with several well known GCN models and show the results improvement compared to existing methods. The source code and data are publicly available at https://gitlab.liris.cnrs.fr/hseba/sffs-gcn.

Im regionalen Fokus dieses Sammelbandes stehen Frankfurt am Main und Offenbach als Teil der Rhein-Main-Region. Dieser räumliche Bezug hat forschungspraktische (z.B. Zugänglichkeit von Expert_innen), aber auch inhaltliche Gründe, da sich in dieser Region Wohnen und die gebaute Umwelt im besonderen Maße als gesellschaftliches Konfliktfeld – gekennzeichnet durch Phänomene wie Büroleerstand, Wohnungsmangel und Widerstand gegen Wohnen als Ware – erweisen und untersuchen lassen. Die Rhein-Main-Region ist wie andere große deutsche Metropolregionen von einem angespannten Immobilienmarkt geprägt, der das Ziel volatiler, d.h. in Bezug auf Umfang und Objekte sehr stark schwankender, Investments ist. Bis 2008 flossen Investitionen vorrangig in den Bürobestand, im Zuge der Finanz- und Schuldenkrise wurden Investments institutioneller Anleger jedoch in den Wohnungsmarkt umgelenkt (Scharmanski 2013; Heeg 2013). Hintergrund hierfür sind einerseits eine steigende Zahl von sog. notleidenden Krediten („non-performing loans“) im Büroimmobilienbereich (vgl. Biedermann et al., Kap. 7) und andererseits anziehende Mieten und Eigentumspreise auf dem Wohnungsmarkt, welche Investitionen in Wohnimmobilien lukrativ werden lassen (Kholodilin/Mense 2012). In der Folge werden vermehrt Luxuswohnungen erstellt und wird preiswerter Wohnraum vernichtet.
Fruit Characteristics of the Joy Peach Cultivars
Authors: Chen Chunxian
Published: March 2023

A trio of peach cultivars, Crimson Joy, Liberty Joy, and Rich Joy, have been recently released by the US Department of Agriculture breeding program at Byron, GA. They ripen at Byron in early to mid-June, late June to early July, and mid-July, respectively. Additional data on their fruit development are needed to understand the ripening process and optimize harvest timing. This study was designed to measure and compare characteristics of ripening fruit harvested weekly from the three Joy cultivars in two trial orchards. Fruit characteristics were significantly different among the three cultivars, the trial locations, and the harvest weeks. Difference in the five size-related characteristics (fruit weight, flesh weight, pit weight, and equatorial and polar diameters) and soluble solid content (SSC) were statistically significant among the three cultivars. ‘Crimson Joy’ had the smallest averages in the size-related characteristics and ‘Rich Joy’ fruit had the largest. ‘Liberty Joy’ had the firmest fruit and least juice volume and blush rating value at maturation. Trees in the commercial block produced larger fruit than those in the Byron research block. Differences among the harvests were statistically significant for all the fruit characteristics, suggesting that the peach fruit experienced dramatic changes as ripening progressed. The weights and diameters, juice volumes, and SSC continued to increase in the harvests although with reduced firmness. Correlation coefficients varied greatly between these fruit characteristics along with R2 and P values. The highest positive correlations were observed among fruit weight, equatorial diameter, polar diameter, and flesh weight. Pit weight was positively correlated with them to a lesser extent. Firmness showed substantial negative correlations with several characteristics, including three weights, two diameters, juice volume, SSC, and blush rating value. SSC and titratable acidity were also negatively correlated. The data confirmed that peach fruit continued to size while ripening and should be useful to determine appropriate harvest timing, which could differ for commercial packing vs. roadside sales.
Risk factors for BRD on cow-calf operations
Authors: Woolums Amelia R.
Published: March 2023

Surveys of cow-calf producers indicate that bovine respiratory disease (BRD) in nursing (preweaned) beef calves is recognized on approximately 20% of operations. In the US BRD is reported to be the leading cause of death in preweaning calves 3 weeks of age and older. As compared to feedlot BRD or dairy calf BRD, relatively little information has historically been available regarding risk factors for the nursing calf BRD. Information regarding risk factors can support the development of management practices that prevent BRD by limiting exposure of calves to risk factors. Evidence available to date indicates that at the calf level, male calves, calves born with a twin, calves born to a heifer, and calves that experience dystocia requiring major assistance are at increased risk for preweaning BRD. At the herd level, nursing calf BRD risk is associated with factors that increase the opportunity for introduction of pathogens new to the herd, calf diarrhea, and events that provide opportunities for close contact among cows and calves. Because risk factors to date have been identified in cross-sectional surveys and thus are not necessarily causative, research is needed to determine whether modification of risk factors identified to date can decrease subsequent BRD on cow-calf operations.
Making It Work: Women's Ways of Leading
Authors: Harris Charlotte Matthews , Smith Penny L , Hale Rosalind Pijeaux
Published: March 2023

An examination of women in leadership from a feminine perspective or point of view reveals that afemale organizational culture exists and that women exhibit ways of leading that are distinctivelydifferent from the ways men lead. Women's ways of leading are consistent with recent trends inleadership research and theory and provide a model for education that could lead to "a more caringcommunity and a safer world" (Noddings, 1991, p. 70). Yet, historically, society has been viewed asdivided into two domains""the public sphere and the private sphere. Predominantly male, the publicsphere "demands independence, rationality, and self-reliance," whereas the private sphere, predominantlyfemale, reflects "dependence, emotionality, and support" (Forisha, 1981, p. 10). That which is public isprimary, and that which is private is secondary. Since women have been relegated to the private sphere,their values and experiences have not been considered until recently.
Teachers' Perceptions of "smart" girls: What does it mean for developing girls and young women into leaders?
Authors: Jacobs Jacqueline E.
Published: March 2023

Based on two studies, one of girls and young women in middle schools and high schools (n=802) and arandom sample of their teachers (n=41), there is evidence that girls and young women are confident in theirviews of themselves as "smart" and do not see any differences in how they are treated by their peers orteachers for being "smart". The evidence from the teachers supports these perceptions and provides aglimpse at what characteristics/behaviors teachers perceive as identifying girls and young women as"smart." This evidence suggests that there is confidence among girls and young women relative to being"smart" which may well provide a basis for the development of skills which are needed to ensure girls andyoung women become leaders in our society.

While the progress of women into higher education presidencies is dramatic, it is also, in the words of oneexperienced woman president, "not exactly a lot!" In the 15 years from 1986 to 2001, the American Councilon Education (ACE) reports that the percentage of women presidents increased from 9.5 to 21.1 (TheAmerican college president, 2002). Of these women, 26.8% led two-year institutions; 18.7% ledbaccalaureate schools; 20.3% led comprehensive universities; and only 13.3% headed doctorate-grantingschools; with the remaining 14.8% guiding specialized schools.
The Educational Leadership of Anna Julia Haywood Cooper
Authors: Johnson Karen
Published: March 2023

Anna Julia Haywood Cooper (1859-1964) was one of the most influential African-American educators ofthe late 19th and early 20th centuries. Heralded as a community activist, author, and scholar, Cooperdedicated her entire life to the education and empowerment of African-American youth and adults. Hercommitment and passionate belief in the power of education as a vehicle to social, economic, and politicalfreedom was a driving force in her life. As a classroom teacher, high school principal, and college president,Cooper initiated and implemented pioneering educational reforms, which reflected her distinctive vision ofeducation for Blacks, females, and working-class people. Cooper's vision of education challenged thedominant discourse concerning how African-Americans, females, and working-class adults should beeducated by offering alternative ways of educating these disenfranchised groups. Indeed, her ideals ofeducation were framed by her social location as a Black woman in an era when few Blacks and few womenwere educated, and when most were disenfranchised.
Motivational Factors Influencing Women's Decisions to Pursue Upper-Level Administrative Positions at Land Grant Institutions
Authors: Cox Kelline Sue , Salsberry Trudy
Published: March 2023

Much of the research on women advancing in higher education has been focused on the external barriers and how to break down the barriers. This study acknowledged that external barriers existed, but determined that a new approach needed to be explored for implementing new initiatives geared toward advancing women to upper-level administrative positions (e.g., president, vice-president or provost). Using the elements of Bandura's Model of Reciprocal Determination, specifically self-efficacy, personal behavior, environment, and the interaction of all three, this qualitative study examined women in upper-level administrative positions and investigated what influential factors were responsible for motivating them to this achievement
Correlation of Female Trinidadians, Bermudians, Sri-Lankans' Feminist Identity Development, and Self-Esteem: Reflection of Social Role Theory
Authors: Bissessar Charmaine
Published: March 2023

Self-esteem and feminist identity development share symbiotic dyads. Agentic and communal characteristics shape females' identity and determine whether they see themselves as products or producers of their social system and display descriptive and/ or injunctive or prescriptive patterns of behavior. The aforementioned theoretical frameworks form the backdrop for my research which involved 40 Trinidadians, 20 Bermudians, and 38 Sri Lankans females ages 18 to 64. In my quantitative methodology study, I incorporated the Feminist Identity Development Scale (FIDS, Bargad & Hyde, 1991) and Rosenberg's (1965) Self-Esteem Model (RSE) to determine whether or not there was a significant correlation between Trinidadian and Bermudian females' self-esteem and feminist identity development. Descriptive statistics implementing a correlation matrix with the use of Mega Stats Add-Ins with Microsoft Excel determined that no significant correlation existed between Trinidadian and Bermudian female participants for their RSE and FIDS respectively. Additionally, one way ANOVA tests showed the correlation: (a) within sample group- Trinidadian females with no significant correlation between their FIDS and RSE; (b) within sample group- Afro and Indo- Trinidadians there was no significant correlation of RSE and a slight positive correlation of .0467 between participants' subscales of FIDS; (c) within sample group- there was no significant correlation between Bermudian participants' RSE but a significant negative correlation between subscales of FIDS; (d) within sample group- Sri Lankan females showed a significant negative correlation between subscales of FIDS; (e) among sample groups- Bermudian, Sri Lankan, and Trinidadian females there was a significant negative correlation among their RSE and no significant correlation of their FIDS. The findings corroborate other conclusions on FIDS and RSE and the social role theory.
Some Ethiopian Women Leaders' Perceptions about Their Leadership
Authors: Tsegay Tesfay S.
Published: March 2023

This research aimed at exploring the perceptions of women leaders on their performance on three key areas of leadership - on ten leadership qualities, type of power they use and their leadership performance - as perceived and assessed by the leaders themselves. A total of 45 women leaders 15 each from public, NGO and private sectors participated in the study. Two questionnaires were distributed each consisting of two parts. The first part solicited information, among others, about a participant's organization, position in and number of years in the organization as well as years in current position, educational level and whether or not she has participated in leadership training programs. The second part of the questionnaire contained three sets of questions on the three key leadership areas. The findings of the study show that with minor differences among them, private sector leaders seem to possess the ten leadership qualities better than and followed by NGO and public sector leaders. Both in terms of individual and group performance, NGO leaders seem to use power of the person to the highest degree followed by private sector leaders and last come public sector leaders. NGO leader seem to be more able to work with and through other people (Stateswomanship) followed by both private and public sector leaders. The overall average performance rating for all sectors in the three performance types puts NGO women leaders at the top followed by private and public sector leaders. The overall findings indicate that the relatively higher performance of women sectoral leaders in the study could be attributed to their corresponding high levels of educational qualification, over all work experience and experience in leadership positions, and training on leadership.
Female's Journey to the State Superintendency
Authors: Sarah Tanner-Anderson
Published: March 2023

Several studies have emerged over the past several decades attempting to pinpoint potential factors for occupational inequity and inequality for prospective and current female educational leaders.  Although women are increasingly obtaining leadership positions in the field, one position has remained elusive to the aspiring female educational leader: the superintendency (Bilken & Brannigan, 1980; Brunner & Björk, 2001; Brunner & Grogan, 2007; Dana & Bourisaw, 2006; Mertz, 2006; Shakeshaft, 1987).  Overcoming societal perceptions, handling hardships associated with attaining and maintaining one’s position, and building powerful, meaningful relationships are some of the foci of previous research; however, there seems to be a piece missing from the current available literature.  While one may evaluate the struggles females have faced in attaining district-level superintendent positions, research detailing the female’s journey to the state superintendency remains incredibly limited to nonexistent.  Through a postmodern-feminist lens, this qualitative study employs Harter and Monsour’s (1992) Self-in-Relationship (SIR) interview protocol, in addition to open-ended interview questions, to explore a conceptual framework blending perceptions, reality, and relationships that potentially impact females on the journey to and in service within the state superintendency.  From a constructivist, Grounded Theory approach, the study investigates a glaring gap in the current available literature in an effort to answer the overarching question:  Do female superintendents perceive gender as playing a role in fulfilling one’s duties at the state level?

We describe key concepts and examples of the ethos of ethnic studies.
Urban Mathematics Education Research
Authors: Dubbs Christopher
Published: March 2023

As Foucault’s ironic approach to history is to suggest that looking at our past can help us to change the future, I contend that connections make the best disruptions. To wit, I introduce citation networks to make connections between articles and citations as a way of disrupting assumptions about what has been and can be done in the name of mathematics education research. The purpose of this paper is to introduce citation networks, a novel method for identifying field connections, and a theory of spatiality that deploys the metaphors of bubbles and foams to imagine disruptions. After introducing the method and theory that guide this investigation, I introduce and describe the foams of the research published in the Journal for Research in Mathematics Education and Educational Studies in Mathematics during the 2010s. In doing so, I show what topics of inquiry constitute the dominant research foci of our field, or at least of our field as it is published in these mainstream mathematics education journals. Later, I read these maps with a critical lens towards the foci to discern what is marginalized and excluded, namely the urban. This research builds on earlier work that names the ghettoization of urban mathematics education research and provides a critical interrogation of the ways that urban research is marked and marginalized within dominant mathematics education research journals. I conclude by situating the role of the Journal of Urban Mathematics Education as a place to blow bubbles, a place to reconfigure what we can see, say, think, and do in the name of (urban) mathematics education research.
Practices Worthy of Attention: A Search For Existence Proofs of Promising Practitioner Work in Secondary Mathematics
Authors: Paek Pamela L.
Published: March 2023

The goal of the practices worthy of attention (PWOA) project was to surface in-innovative practices currently in use by urban schools and districts that show promise of improving students’ secondary mathematics performance. Each school and district explored has a different perspective and a unique set of practices in place to improve secondary mathematics achievement. The goal of this project was not always to discover innovations in how practitioners address similar issues, but rather to document what practitioners are doing to strengthen secondary mathematics education. Thus, although the practice highlighted might be commonplace, the specific structures and strategies being employed by the school or district to implement it are worthy of attention. A cross-case analysis of the 22 practices revealed two main categories: raising student achievement and building teacher capacity.
Considering the Social Justice Mathematical Journey of Secondary Mathematics Preservice Teachers
Authors: McLeman Laura , Piert Joyce
Published: March 2023

In this essay, the authors share some of their journey as they seek to make sense of what it might mean to prepare secondary mathematics preservice teachers to teach mathematics for social justice. The focus on how to prepare mathematics teachers to critically consider the world around them and to further develop the dispositions to become agents of change has been discussed in the research literature. What it might “look like” to enact this type of programmatic-level teaching at a college or university, however, has rarely been examined. Through the sharing of their thoughts and reflections, the authors hope others might draw inspiration to reconsider the teaching of mathematics courses for social justice at the program level.
Latinas and Problem Solving: What They Say and What They Do
Authors: Guerra Paula , Lim Woong
Published: March 2023

In this article, the authors present three adolescent Latinas' perceptions of ideal mathematical competencies, their perception of their individual "abilities" in mathematics, and their work on a mathematics problem-solving task. Results indicate that these Latinas recognize flexible mathematics as the ideal mathematical competency in problem solving but demonstrate rigid mathematics in the problem-solving task. Reasons for the discrepancy between the three Latinas' perceptions of ideal mathematical competencies and their own work on mathematical tasks are discussed. Implications related to opportunities for girls of color to pursue careers in STEM fields are discussed as it relates to flexible problem-solving skills in mathematics.
Learning to Leverage Children's Multiple Mathematical Knowledge Bases in Mathematics Instruction
Authors: Turner Erin E. , Foote Mary Q. , Stoehr Kathleen Jablon , Roth McDuffie Amy , Aguirre Julia Maria , Bartell Tonya Gau , Drake Corey
Published: March 2023

In this article, the authors explore prospective elementary teachers' engagement with and reflection on activities they conducted to learn about a single child from their practicum classroom. Through these activities, prospective teachers learned about their child's mathematical thinking and the interests, competencies, and resources she or he brought to the mathematics classroom, and then wrote reports that included instructional suggestions as to next steps to further the child's growth in mathematics. The authors' analyses of these reports indicate that there were a variety of ways which prospective teachers made connections to one or more of their child's knowledge bases. In a high percentage of cases, prospective teachers attended to one of these knowledge bases, indicating that they were attending to particularities about their child and developing the dispositions to continue to do so. Implications for research and practice are discussed.

Background: Medical science is perceived as a stressful educational career, and medical students experience monstrous stress during their undergraduate studies and internships because of its depth and competitiveness. Prolonged stress can cause health problems, hamper academic achievements, and affect patient care. Objectives: The present study aimed to assess the prevalence of stress and its association with resilience, as well as the coping strategies adopted by medical students. Material & Methods: This was a cross-sectional study conducted among medical undergraduate students studying at a tertiary care hospital situated in Aurangabad, Maharashtra, between June and July 2022. Using Cochrans formula and the previous studys prevalence of 51.1%, 425 medical students from first year to internship were included. A self-administered questionnaire consisting of Sociodemographic characteristics, items from the Kessler 10 inventory, and the BRIEF resilient coping scale were used. Results: The overall response rate was 79.11%, with 380 out of 425 students returning the questionnaire. The study found that 57.6% of medical students were suffering from high levels of stress, and the highest prevalence was among the 1st year students, followed by the internship students, and then the final year students. Stress was classified as mild (13.9%), moderate (8.9%), severe (34.7%), or likely to be well (42.4%) on the Kessler 10-item inventory scale. Academic factors are a greater perceived cause of stress. The religion, present address, medium of education and BRCS coping score had significant impact on presence of stress.(p=0.027, p=0.03, p=0.001,p=0.001 ) Conclusion: The study recommended that consideration be given to program decision-makers and health decision-makers to focus on significant actions to reduce the academic stress perceived by medical students. Preventive mental health services could be made an integral part of routine clinical services for medical students, especially in the initial academic years, to prevent such occurrences.

Background: Hearing impairment in children constitutes a particularly serious obstacle to their optimal development. Early detection of hearing impairment is vital since early intervention including hearing aids and speech therapy can be initiated at the earliest. The aim of the study was to determine the risk factors associated with children with hearing loss and to assess degree of hearing loss using BERA. Materials and methods: 50 patients below 10 years of age attending ENT OPD with h/o hearing loss were taken for the study from January 2021 to January 2022 and were subjected to detailed history taking and clinical examination. Then the patients were subjected to BERA and the results were analysed. Result: The most common risk factor for hearing loss in this study is h/o consanguinity (40%) followed by birth asphyxia(9%) and then hyperbilirubinemia(8%). The other risk factors include h/o ototoxic drug intake(5%), low birth weight(4%), h/o intracranial infections(3%) and family h/o congenital hearing loss(1 %) Conclusion:Newbornscreening is mandatory to identify hearing loss in the prelinguistic period to reduce the burden of handicap in the society. BERA should be carried out as a routine procedure to detect hearing impairment in high risk children and rehabilitative measures should be started as early as possible.

Goal: this в paper investigates the diversity of corporate social responsibility (CSR) practices in the Russian context. The purpose of this paper is to study how a heterogeneous context, commonly found in rising economies, shapes the emerging CSR practices of business organizations operating in Russia. Methodology: an institutional perspective that draws on the contextual multilevel approach guides our study. In our theoretical framing we assume that organizational fields play a key role in shaping CSR practices. This is applied to empirical investigation of organizational CSR practices. To inform our analysis we used desk research and an empirical dataset that consists of interviews with local business owners and managers representing a wide range of business organizations operating in Russia. Findings: based on an exploratory qualitative inquiry, we distinguish between four types of organizational CSR practices co-existing in Russia: global, crossvergent, authentic and irresponsible. Our findings demonstrate that business organizations populating one organizational field share homogeneous characteristics of CSR practices. Originality and contribution: the distinctions among CSR practices of business organizations belonging to different organizational fields are explained by the markets where they operate, core stakeholders, response mechanisms to prevailing institutional pressures and the dominant legacy of CSR.
