Interest in the gender gap in the physical sciences has been ongoing for a number of years. This study aimed to explore differences in gender based on self-perception. The use of a post-examination survey was used to examine the role of gender in grade perception in chemistry courses over a several-year period. This included courses for non-science majors, health science majors, and traditional chemistry courses for science majors. Self-reported data was collected after the completion of examinations and analyzed to explore the connection between gender and the student’s postdiction (a prediction after the completion of the examination) of their examination score as it related to the Kruger-Dunning effect. While male and female students followed the same general patterns, it was found that for most students, male students tended to predict higher scores than female students while seeing little difference in actual performance. The lowest performing students (those scoring less than 50% on examinations) showed little difference in the accuracy of their postdictions based on gender. © 2024 National Science Teaching Association.

Resisting Divide-and-Conquer Strategies in Education: Pathways and Possibilities examines the ways in which divide-and-conquer strategies operate in the American public education system. In U.S. education, these mechanisms are endemic and enduring, if not always evident. Coordinated, strategic, well-funded, politically-viable campaigns continue to stoke fear, othering, villainization, and dehumanization of minoritized groups, pushing false and problematic narratives that inhibit progress toward social justice. Weaponizing hegemony and leveraging misinformation, reactionary agents and institutions seek to suppress truth, block access to democratic participation, and dismantle education and other sites of emancipatory possibility through the strength of divide-and-conquer mechanisms, pitting relatively disempowered groups against one another to preserve the dominant social order. Readers of this book will encounter conceptual and critical interrogations of divide and conquer. The text will help facilitate inquiry and engagement into how divide and conquer operates and how it can be resisted. It looks at the history of the phenomenon, as well as its current state, especially as it relates to education. What insights and lessons might we learn from a focused examination of divide and conquer, and what strategies of resistance are both possible and necessary for challenging it? This text is designed for undergraduate and graduate classrooms in education and social sciences. Part I, Ideology and Sociopolitical Contexts, dissects how divide-and-conquer mechanisms operate ideologically and sociopolitically. Part II, Policies and Practices, focuses on how divide-and-conquer mechanisms shape exclusionary U.S. educational policies and practices. Part III, Resistance and Liberation, documents efforts of liberatory communicative, curricular, and pedagogical possibilities. Each chapter concludes with a set of critical questions for reflection and engagement.Perfect for courses such as: Foundations of Education; Schools and Society; Schooling in America; History of Education; Philosophy of Education; Sociology of Education; Social Studies; Critical Theory in Education

The project of engaging undergraduates in research methods courses is an outstanding challenge for social work educators. Anxiety about the subject is common, for both students and instructors. Further, students’ wariness may reflect historical trauma and their knowledge about the ways in which research has been used to oppress people of color; lesbian, gay, bisexual, transgender, queer or questioning, intersex, asexual or ally, and other sexual and gender minorities communities; and other marginalized populations. This teaching note offers reflections and experiences about developing an undergraduate social work research methods course that uses antioppressive pedagogies to create student-centered learning with experiential team-based activities and ongoing critique about the role of power and privilege in research. Specific teaching resources and strategies are shared. © 2024 Council on Social Work Education.

Background: The relationship between physical activity (PA) and bullying behaviors is unclear among adolescents with overweight/obesity (OW/OB). The current study examined the likelihood of engaging in bullying behaviors by differing physical activity behaviors in adolescents with OW/OB. Method: Analyses included 9114 adolescents with OW/OB, ages 10–17 years, from the combined 2018–2019 National Survey of Children’s Health. Adolescents were grouped by PA level (0 days, 1–3 days, 4–6 days, every day); outcome variables included bullying behaviors (perpetrator, victim, both, or neither), sport participation, behavioral conduct problems, depression, difficulty making new friends, and excessive arguing. Separate adjusted logistic regression models assessed the odds of each outcome comparing differing PA levels. Results: Compared to their inactive peers, adolescents with OW/OB that engaged in at least 1 day of PA were significantly less likely to be victims of bullying (OR = 0.80; 95% CI (0.68, 0.93)) and to be both a bully perpetrator and victim (OR = 0.77; 95% CI (0.64, 0.94)). Participation in sports significantly increased the likelihood of being a bully perpetrator (OR = 1.50; 95% CI (1.06, 2.11)) and decreased the likelihood of being a bully victim (OR = 0.83; 95% CI (0.75, 0.92)) in adolescents with OW/OB. Additionally, adolescents with OW/OB that participated in PA were less likely to experience adverse psychosocial outcomes. Conclusions: Findings suggest PA participation (≥ 1 day/week) may reduce the likelihood of bully victimization and both (perpetration and victimization) and attenuate adverse psychosocial outcomes in adolescents with OW/OB. However, sport participation may increase bully perpetration while decreasing bully victimization in adolescents with overweight/obesity. © The Author(s), under exclusive licence to Springer Nature Switzerland AG 2024.

Urban air pollution, a combination of industry, traffic, forest burning, and agriculture pollutants, significantly impacts human health, plants, and economic growth. Ozone exposure can lead to mortality, heart attacks, and lung damage, necessitating the creation of complex environmental safety regulations by forecasting ozone concentrations and associated pollutants. This study proposes a hybrid method, RFNN-GOA, combining recurrent fuzzy neural network (RFNN) and grasshopper optimization algorithm (GOA) to estimate and forecast the daily ozone (O3) in specific urban areas, specifically Kopački Rit and Osijek city in Croatia, aiming to improve air quality, human health, and ecosystems. Due to the intricate structure of atmospheric particles, modeling of O3 likely poses the biggest challenge in air pollution today. The dataset used by the proposed RFNN-GOA model for the prediction of O3 concentrations in each explored area consists of the following air pollutants, NO, NO2, CO, SO2, O3, PM10, and PM2.5; and five meteorological elements, including temperature, relative humidity, wind direction, speed, and pressure. The RFNN-GOA method optimizes membership functions’ parameters and the rule premise, demonstrating robustness and reliability compared to other identifiers and indicating its superiority over competing methods. The RFNN-GOA method demonstrated superior accuracy in Osijek city and Kopački Rit area, with variance-accounted for (VAF) values of 91.135%, 83.676%, 87.807%, 79.673% compared to the RFNN method’s corresponding values of 85.682%, 80.687%, 80.808%, 74.202% in both training and testing phases, respectively. This reveals that RFNN-GOA increased the average VAF in Osijek city and Kopački Rit area by over 5% and 8%, respectively. © The Author(s), under exclusive licence to Springer Nature Switzerland AG 2024.

Symbolic regression techniques are promising approaches to learning mathematical models that fit experimental data. One of the most powerful techniques for symbolic regression is Grammatical Evolution (GE). This evolutionary computation technique explores a space of candidate models that are ensured to be syntactically correct expressions built from a set of arbitrary building blocks and operators. In GE the syntax for these expressions is defined by a problem-specific formal grammar. Therefore, GE can produce an explainable solution (e.g. a formula), not a black-box model. The current contribution assesses the viability of GE for PSF characterization, using real datasets from HST/WFPC2. Our experiments show that our method is able to find the most likely candidate mathematical expression for the PSF shape, and can also model combinations of shapes taken from a predefined family of functions commonly used in astronomy (Gaussian and Moffat PSFs). These results support the hypothesis that the expressive power of GE can be used to tackle the problem of characterization of complex PSF functions, for example, as a necessary step in the prediction of intra-pixel position of stars. © 2024 SPIE.

At the origin of the Universe, an asymmetry between the amount of created matter and antimatter led to the matter-dominated Universe as we know it today. The origins of this asymmetry remain unknown so far. High-energy nuclear collisions create conditions similar to the Universe microseconds after the Big Bang, with comparable amounts of matter and antimatter1–6. Much of the created antimatter escapes the rapidly expanding fireball without annihilating, making such collisions an effective experimental tool to create heavy antimatter nuclear objects and to study their properties7–14, hoping to shed some light on the existing questions on the asymmetry between matter and antimatter. Here we report the observation of the antimatter hypernucleus $${}_{\bar{\Lambda }}{}^{4}\bar{{\rm{H}}}$$, composed of a $$\bar{\Lambda }$$, an antiproton and two antineutrons. The discovery was made through its two-body decay after production in ultrarelativistic heavy-ion collisions by the STAR experiment at the Relativistic Heavy Ion Collider15,16. In total, 15.6 candidate $${}_{\bar{\Lambda }}{}^{4}\bar{{\rm{H}}}$$antimatter hypernuclei are obtained with an estimated background count of 6.4. The lifetimes of the antihypernuclei $${}_{\bar{\Lambda }}{}^{3}\bar{{\rm{H}}}$$and $${}_{\bar{\Lambda }}{}^{4}\bar{{\rm{H}}}$$are measured and compared with the lifetimes of their corresponding hypernuclei, testing the symmetry between matter and antimatter. Various production yield ratios among (anti)hypernuclei (hypernuclei and/or antihypernuclei) and (anti)nuclei (nuclei and/or antinuclei) are also measured and compared with theoretical model predictions, shedding light on their production mechanisms.

For more than a decade, since the US Supreme Court ruled in Citizen’s United (2010), individuals and groups interested in the outcome of elections have increasingly donated to outside groups that avoid the restrictions imposed on candidates and traditional political action committees (PACs). As a result, total election spending more than doubled in the first five years and has continued to increase since then. Although American political advocacy groups refrain from formal electioneering, much of the increase in spending since Citizen’s United has been directed toward election campaigns under the guise of issue-advocacy ads. This raises the question of whether voters perceive a difference between candidate-sponsored ads and campaign-focused issue-advocacy ads. Unexamined is the impact that advertising by outside groups has on voters and whether voters are even aware of the sponsors of the ads they view. This study addresses whether voters can differentiate between ads sponsored by candidates or outside groups. Using an experimental design, we find that viewers cannot determine the sponsor of campaign ads, despite federal requirements for sponsor disclaimers. © 2024 Common Ground Research Networks.

An important reason for the success of the Venetian Paolo Sarpi’s ideas in England is found in the ‘Englishing’ of his printed works, that is, their adaptation and appropriation by printers and translators. During the Venetian interdict (c. 1606–1608), Sarpi’s tracts were treated as timely, informative, and politically useful news. Englishing consisted of re-writing titles by adding bombastic phrases, changing printers’ ornaments, and adding marginalia to help readers unfamiliar with Italy. In the History of the Council of Trent, published in 1619 (Italian) and 1620 (English), the Englishing became more substantive – adding lengthy prefaces, inserting words into Sarpi’s text, and including the translator’s name. The prefaces framed the book’s contents, while the translator’s name provided authority. The additional words made the English History even more partisan than the Italian Historia. Publishers and translators modified Sarpi’s works to produce aggressive readings that diverged from his own political and religious goals.

The 30 yr orbit of the Cepheid Polaris has been followed with observations by the Center for High Angular Resolution Astronomy (CHARA) Array from 2016 through 2021. An additional measurement has been made with speckle interferometry at the Apache Point Observatory. Detection of the companion is complicated by its comparative faintness—an extreme flux ratio. Angular diameter measurements appear to show some variation with pulsation phase. Astrometric positions of the companion were measured with a custom grid-based model-fitting procedure and confirmed with the CANDID software. These positions were combined with the extensive radial velocities (RVs) discussed by Torres to fit an orbit. Because of the imbalance of the sizes of the astrometry and RV data sets, several methods of weighting are discussed. The resulting mass of the Cepheid is 5.13 ± 0.28 M ⊙. Because of the comparatively large eccentricity of the orbit (0.63), the mass derived is sensitive to the value found for the eccentricity. The mass combined with the distance shows that the Cepheid is more luminous than predicted for this mass from evolutionary tracks. The identification of surface spots is discussed. This would give credence to the identification of a radial velocity variation with a period of approximately 120 days as a rotation period. Polaris has some unusual properties (rapid period change, a phase jump, variable amplitude, and unusual polarization). However, a pulsation scenario involving pulsation mode, orbital periastron passage, and low pulsation amplitude can explain these characteristics within the framework of pulsation seen in Cepheids.

Faculty of color are constantly experiencing trauma and racial inequities in inherently Eurocentric educational spaces where their histories, knowledge, and experiences are delegitimized and marginalized. Employing critical race feminism (CRF) and White racial identity development model, this article details ways in which two Chinese international women instructors grappled with tensions and trauma and celebrated (small) joys and successes within Predominantly White Institutions (PWI) in the United States. We drew on duoethnography, a dialogic methodological approach grounded in social justice, to make meaning of, (re)construct, and advance racial equity in pedagogy. We examined and analyzed four sources of data: our personal narratives, transcripts of eight Zoom meetings, reflection journals, and informal conversational exchanges. We identified three strategies for navigating dissonance and conflicts: 1) being vulnerable, 2) recognizing shared and differing marginalization or privileges, and 3) building allies intentionally and strategically. © 2024 Informa UK Limited, trading as Taylor & Francis Group.

Food insecurity is a detriment to the health and academic success of college students nationwide, increasing the need for innovative interventions. This cross-sectional study administered an online survey to 140 students attending a Northeastern public university to understand student interest in a student-sustained grocery program. The majority of students (53.6%) were food insecure (FI), measured with the USDA 6-item survey, as well as upperclassmen. Results identified that FI students may be most interested in a food pickup program that provides them with cooking classes, snack foods, and ingredients for 2–6 meals at a cost between $24.50 and $26.90 per week. © 2024 Taylor & Francis Group, LLC.

Purpose The purpose of this study is to examine the relation between product market competition and audit fees by using firm-level product market competition measures and mitigating the endogeneity issues. Design/methodology/approach This study uses 12,136 US firms from 2004 and 2019. To ensure the robustness of the main findings, this study uses three firm-level product market competition measures and import trade tariff rate reductions of the USA as a quasi-natural experiment. This study also performs three cross-sectional tests and validation tests. Findings This study demonstrates that there is a negative relation between product market competition and audit fees and establishes a causal relation. Moreover, it reveals that the findings become more pronounced when auditors possess industry-specific expertise, when client firms are younger, and when operating within more homogeneous industries. Additionally, a validation analysis supports the findings. Practical implications This study offers significant insights for regulators by highlighting how product market competition plays a constructive role in overseeing firm management. Originality/value The authors contribute to the existing literature by showing that there is a negative association between product market competition and audit fees after controlling external monitoring mechanisms. The authors also find the causal relation. These findings indicate that competitive pressures originating from product markets exert a significant influence on disciplining a client firm’s management.

How physical education teachers approach standards-based assessment of the new National Physical Education Standards is yet to be determined. But the use of technology for assessments may be one way to support and empower students in the education process toward physical literacy. This article focuses on the ways in which educators have adopted a particular technology, called Plickers, and how its use as an assessment tool can move physical education teachers’ practice forward. © 2024 SHAPE America.

The COVID-19 pandemic has challenged lives globally in unprecedented ways. While numerous studies have discussed the impact of this pandemic on human lives, this descriptive study examined how this pandemic affected personal well-being (PW) for members of Indian higher education in the early phase of the pandemic in 2020 when there were no vaccines and remedies available. Research participants (n = 551) were faculty members, graduate students, and non-teaching staff in Indian higher education. At the time of data collection, when all campuses were closed, all participants were functioning in their roles in the academic communities via virtual platforms. This descriptive study, based on a mixed-methods research design with concurrent triangulation strategies, collected data from all regions of India. Resulting data identified and discussed the impact of the pandemic on six domains of PW in the life of participants: (a) self-care; (b) professional growth; (c) quality of interrelationship within the family; (d) relationships with significant others outside of the family; (e) process of experiencing/facing and addressing challenges; and, (f) relationship with spirituality/transcendental dimensions. The relevance of the last domain may be unique to Indian participants’ socio-cultural context and ethos. The findings and discussion explain how PW is a composite of all these six domains, and the pandemic expanded the notion of PW for the members of Indian higher education. Further, the findings also provided a general orientation on how educational leadership teams and institutions can enhance at least three specific dimensions of their community members and thus increase the likelihood of improving the quality of their professional and personal life. The findings may also have relevance for academic communities worldwide and inform clinicians working with members of academic communities, educational institutions, and policymakers. © Penerbit Universiti Sains Malaysia, 2024.

Measurements of exclusive J/ψ, ψ(2s), and electron-positron (e+e-) pair photoproduction in Au+Au ultraperipheral collisions are reported by the STAR experiment at sNN=200GeV. We report several first measurements at the BNL Relativistic Heavy Ion Collider, which are (i) J/ψ photoproduction with large momentum transfer up to 2.2(GeV/c)2, (ii) coherent J/ψ photoproduction associated with neutron emissions from nuclear breakup, (iii) the rapidity dependence of incoherent J/ψ photoproduction, (iv) the ψ(2s) photoproduction cross section at midrapidity, and (v) e+e- pair photoproduction up to high invariant mass of 6GeV/c2. For measurement (ii), the coherent J/ψ total cross section of γ+Au→J/ψ+Au as a function of the center-of-mass energy WγN has been obtained without photon energy ambiguities. The data are quantitatively compared with the Monte Carlo models STARlight, Sartre, BeAGLE, and theoretical calculations of gluon saturation with color glass condensate, nuclear shadowing with leading twist approximation, quantum electrodynamics, and the next-to-leading-order perturbative QCD. At the photon-nucleon center-of-mass energy of 25.0 GeV, the coherent and incoherent J/ψ cross sections of Au nuclei are found to be 71%±10% and 36%±7%, respectively, of that of free protons. These data provide an important experimental constraint for nuclear parton distribution functions and a unique opportunity to advance the understanding of the nuclear modification effect at the top RHIC energy. © 2024 American Physical Society.
