Identifying facilitators and barriers to implementing the Say Something Anonymous Reporting System in Miami-Dade County, USA: a qualitative study
Authors: Lee Esther , Scott Briana A , Hsieh Hsing-Fang , Zimmerman Marc , Rusch Amy , Heinze Justin
Published: October 2024

Background

Multiple anonymous reporting systems (ARS) have been implemented to prevent school violence and improve school climate. This study examines the facilitators and barriers to implementation and the role and usability of the Say Something Anonymous Reporting System (SS-ARS).

Methods

10 qualitative interviews with key staff and administrators from intervention schools in the Miami-Dade County School District were conducted between July and December 2020. Using a thematic framework analysis of interview transcripts, we identified major themes related to the SS-ARS.

Results

Students used the SS-ARS to report issues related to violence, mental health and substance use. The SS-ARS provided training and safe reporting channels, enabling prompt responses from administrators. Successful anonymous reporting system implementation requires ongoing training for students and personnel, a multidisciplinary response team and integration into a comprehensive school safety effort.

Conclusion

Our study highlights key facilitators and barriers to implementing ARS in schools, offering three takeaways for practitioners: (1) include ongoing training for students and personnel, (2) establish a multidisciplinary team to respond to reports and integrate ARS into a comprehensive safety effort and (3) encourage reporting on a range of concerns. Interviews were conducted with school personnel, with findings primarily reflecting their perspectives, thereby limiting the ability to generalise the findings to students. Although conducted in schools within Miami-Dade County, an urban US county, the findings may be relevant for practitioners implementing ARS or similar initiatives in educational settings globally, given the ubiquity of violence and mental health issues among adolescents.
Ensembled Pretrained Model-Based Adaptive Sequential Trace Recognition for Moving Objects
Authors: Zhang Fan , Bao Kai , Hu Yunyun
Published: October 2024

In this paper, we propose an adaptive continuous trajectory recognition method for badminton sports scenarios. First, we adopt an integrated pre-training model with high generality and expressive ability as the infrastructure. By pre-training large-scale badminton game data, the model can learn the features of badminton sports from rich and diverse trajectory data. Second, to adapt to the trajectory differences in different scenarios, we introduce an adaptive mechanism. By extracting and encoding features from real-time acquired badminton motion trajectories, the model can adjust its own parameters and weight assignments according to the changes in the current scene to optimally recognize and track the motion targets. The algorithm also employs the Kalman filter aggregation Enhanced Correlation Coefficient (ECC) method of the motion model to improve the prediction accuracy. Finally, a series of experiments and comparisons are conducted to validate the effectiveness of the approach. The results show that our proposed adaptive continuous trajectory recognition method for badminton achieves better performance in different scenarios and various complexities, and has higher accuracy and robustness than the traditional method. The FDA-SSD model operates at 28.7[Formula: see text]fps, which is about 16.5% faster than the traditional SSD. In the target tracking experiments, the target tracking mean squared error is about 1.0%. In the target tracking experiments based on the FDA and geometrically constrained localization method, the root-mean-square error of the target tracking is less than 4.72[Formula: see text]cm.
Minimal generating sets and the abelianization for the quasitoric braid group
Authors: Omori Genki
Published: October 2024

A toric braid is a braid whose closure is a torus link in [Formula: see text]. Manturov [A combinatorial representation of links by quasitoric braids, European J. Combin. 23(2) (2002) 207–212] generalized toric braids that is called quasitoric braids and showed that the subset of quasitoric braids in the classical braid group is a subgroup of the braid group. We call this subgroup the quasitoric braid group. In this paper, we give two minimal generating sets for the quasitoric braid group and determine its abelianization. The minimalities of these two generating sets are obtained from a lower bound by the number of generators for the abelianization.

Authors: Pezzoli Patrizia , McCrory Eamon J. , Viding Essi
Published: October 2024

Antisocial behavior (ASB) refers to a set of behaviors that violate social norms and disregard the well-being and rights of others. In this review, we synthesize evidence from studies using genetically informed designs to investigate the genetic and environmental contributions to individual differences in ASB. We review evidence from studies using family data (twin and adoption studies) and measured DNA (candidate gene and genome-wide association studies) that have informed our understanding of ASB. We describe how genetically informative designs are especially suited to investigate the nature of environmental risk and the forms of gene–environment interplay. We also highlight clinical and legal implications, including how insights from genetically informed research can help inform prevention and intervention, and we discuss some challenges and opportunities within this field of research.

Published: October 2024

The postnatal surge in circulating leptin levels in mice reflects particularly posttranscriptionally controlled release of this hormone from subcutaneous white adipose tissue. Leptinemia in 2-wk-old pups predicts both body weight and adiposity in adult mice fed a high-fat diet. The extent of these effects depends on genetically determined differences in propensity to obesity between C57BL/6 and A/J mice. The leptin effect on adiposity is compromised in the obesity-prone C57BL/6 mice.

Published: October 2024

To our knowledge, our finding in this study shows for the first time that metabolic shifts in ratio of ucOcn to cOcn toward bone resorption are markedly correlated with age-dependent bone loss in male mice. These findings for the effects of aging on bone loss will assist in studying the pathogenesis of human type II osteoporosis.

Published: October 2024

Introduction: Pharmacological treatment of unresectable hepatocellular carcinoma (uHCC) includes sorafenib and lenvatinib, a tyrosine kinase inhibitor, which are linked to low serum levels of carnitine and reduced skeletal muscle volume. Nowadays, atezolizumab plus bevacizumab (Atezo/Bev) combination therapy is recommended as the first-line treatment for patients with uHCC. However, the association with decreased muscle mass or cardiac function is unknown. Therefore, this study aimed to evaluate the effects of Atezo/Bev on skeletal muscle volume and cardiac function in patients with uHCC. Methods: This retrospective study included 55 adult Japanese patients with chronic liver diseases and uHCC treated with Atezo/Bev. Patients were divided into three groups according to age: middle, preold, and old. Serum levels of carnitine and cardiac function were measured before and after 3 weeks of treatment. The psoas muscle index (PMI) was measured before and after 6 weeks of treatment. Results: After treatment, the global longitudinal strain was significantly lower in the old group, whereas the PMI and ejection fraction were significantly lower in the preold and old groups. However, no significant difference in serum levels of total carnitine and those fractions with treatment in each group was found. Cardiac function decreased in the preold and old groups. Conclusion: When treating patients with uHCC by Atezo/Bev, caution should be taken in preold and old patients because they are vulnerable to decreased skeletal muscle mass and deterioration of cardiac function. Strength training and regular monitoring of cardiac function are encouraged in these groups.
Adversarial attacks in signature verification: a deep learning approach
Authors: Hazra Abhisek , Maity Shuvajit , Pal Barnali , Bandyopadhyay Asok
Published: October 2024

Handwritten signature recognition in forensic science is crucial for identity and document authentication. While serving as a legal representation of a person’s agreement or consent to the contents of a document, handwritten signatures de termine the authenticity of a document, identify forgeries, pinpoint the suspects and support other pieces of evidence like ink or document analysis. This work focuses on developing and evaluating a handwritten signature verification sys tem using a convolutional neural network (CNN) and emphasising the model’s efficacy using hand-crafted adversarial attacks. Initially, handwritten signatures have been collected from sixteen volunteers, each contributing ten samples, fol lowed by image normalization and augmentation to boost synthetic data samples and overcome the data scarcity. The proposed model achieved a testing accu racy of 91.35% using an 80:20 train-test split. Additionally, using the five-fold cross-validation, the model achieved a robust validation accuracy of nearly 98%. Finally, the introduction of manually constructed adversarial assaults on the sig nature images undermines the model’s accuracy, bringing the accuracy down to nearly 80%. This highlights the need to consider adversarial resilience while designing deep learning models for classification tasks. Exposing the model to real look-alike fake samples is critical while testing its robustness and refining the model using trial and error methods.
Revision of the nomenclature status and taxonomic implications of two Lepidion species (Gadiformes: Moridae)
Authors: BAÑÓN RAFAEL , BARROS-GARCÍA DAVID , ARRONTE JUAN CARLOS , BALDÓ FRANCISCO , DE CARLOS ALEJANDRO
Published: October 2024

Lepidion lepidion and Lepidion eques are two nominal species of the genus Lepidion (Moridae) from the Mediterranean Sea and the North Atlantic Ocean, respectively. Following the publication of the latter species, several authors highlighted the morphological similarities between them, questioning their taxonomic relationship. Despite these reasonable doubts, the two species have long been considered as valid and separate species. Since the 2010s, a series of integrative studies, combining morphological and molecular analyses, have demonstrated that L. eques is a junior synonym of L. lepidion. However, the former has continued to be used inconsistently in biodiversity databases and ichthyological literature. Thus, while the “Catalog of fishes” immediately incorporated this new status, the databases “FishBase” and “WoRMS” did not, maintaining the validity of both species. Consequently, in the scientific literature, only a few authors adhere to the synonymy relationship, naming the Atlantic species as L. lepidion, while most maintain the older nomenclature of L. eques. These two nominal species represent an interesting case study on the application of taxonomic nomenclature and how the different criteria for incorporating new species affect the scientific community.

Authors: MARTYNENKO NIKITA A. , SHKURINA NATALIYA A. , GUSEV EVGENIY S.
Published: October 2024

This paper describes a new species of Mallomonas discovered in a swamp area in Russia. The species was identified based on scale morphology, examined using scanning and transmission electron microscopy, and subjected to molecular analysis. The new species, Mallomonas okhapkinii sp. nov., belongs to the section Planae and is most similar in scale and bristle ultrastructure to M. matvienkoae sensu stricto. Phylogenetic analysis, performed using a concatenated dataset of nuclear-encoded small subunit rRNA and plastid-encoded rbcL genes, revealed that the strains of the new species form a distinct clade with high statistical support, closely related to the clade of M. paragrandis and M. sorohexareticulata. This species was found in only one habitat.
New data on the stomatocysts of Spiniferomonas septispina Nicholls (Chrysophyceae, Chromulinales)
Authors: BESSUDOVA ANNA , FIRSOVA ALENA D. , LIKHOSHWAY YELENA V.
Published: October 2024

Morphotypes of stomatocysts in the Chrysophyceae class can serve as an additional criterion for determining species' taxonomic affiliations. This study provides a detailed description of the stomatocyst morphotype of Spiniferomonas septispina, a species with controversial taxonomic status owing to its structural similarity with Chrysosphaerella annulata. Analysis of the known morphotypes of Spiniferomonas stomatocysts reveals common features, including the presence of a collar or collar complex and an annulus. The stomatocyst morphotype of S. septispina exhibits ornamentation and a widely flared conical collar typical of Spiniferomonas species, distinguishing it from Chrysosphaerella. Based on these findings, we conclude that S. septispina should be classified under the genus Spiniferomonas. Additionally, the formation of S. septispina stomatocysts occurs in October in Lake Baikal at water temperatures ranging from 8.8 ℃ to 9.6 ℃.

Published: October 2024

Perilimnastes aura, a species found in Sekong province, Laos, is described as new. Its habit and morphology of leaves, inflorescences, flowers, and capsules match all diagnostic features of Perilimnastes. It most closely resembles P. suberalata in the quadrangular stems, unequal leaves, and glabrescent, oblanceolate to broadly elliptic leaf blade, but differs in the acute leaf apex (vs. acuminate), 1–3-flowered inflorescence (vs. 1-flowered), quadrangular hypanthium (vs. obtusely quadrangular) and broadly triangular, 1.8–2.2 mm long calyx lobes (vs. linear, 8–10 mm long). Information on habitat, ecology, and a preliminary assessment of the conservation status are also provided for the new species.
A master in disguise? The rediscovery of Misumena bicolor Simon, 1875 (Araneae: Thomisidae)
Authors: BACH ALEXANDER , LAUTERBACH STEPHAN , ASTRIN JONAS J. , THORNS HANS-JÜRGEN , BAUER TOBIAS
Published: October 2024

Misumena bicolor Simon, 1875, an enigmatic species known only from the male holotype collected on Corsica (France), has remained elusive since its initial description. In this study, we report new occurrences of M. bicolor from Sardinia (Italy) and Bavaria (Germany) based on male material, considerably expanding its known distribution. Employing an integrative taxonomic approach encompassing both morphological and COI (barcode) analyses, we confirm M. bicolor as a valid species. As the male of M. bicolor apparently has a distinct coloration, we complement the known distributional data with possible sightings of photographic observations from various naturalist portals and hereby provide additional evidence for the establishment of the species on the French mainland and in Germany.
Coordinator and Young Adult Perceptions in Attracting and Retaining Chicago Youth in Out-of-School Time Programming
Authors: Inoa Rafael , López Fausto
Published: October 2024

Youth from families with greater economic means have seen an increase in their participation in extracurricular activities, while the participation levels of youth from working class families have decreased. Knowing the benefits to youth participation in extracurricular activities, communities where youth of marginalized backgrounds reside have an obligation to engage their youth in activities offered through school and community out-of-school time programs. Interviews and focus groups with program coordinators and young adults were conducted to identify how youth in Chicago have been attracted, engaged, recruited, and retained in out-of-school time programs. Program aspects and strategies used to connect with youth and their families emerged, some of which have been previously found in the relevant literature to be positively related to youth outcomes, and some of which are specific to youth who identify as Latine and youth who identify as male. Practical implications and suggestions for future research are further discussed.
Equipping Preservice Teachers for Data Use: A Study of Secondary Educator Preparation Programs in Virginia
Authors: Hock Michelle , Moon Tonya R. , Meyers Coby V.
Published: October 2024

Because data-informed decision-making (DIDM) can help teachers meet diverse learners’ needs (van Geel et al., 2016), educator preparation programs (EPPs) must ensure that preservice teachers (PSTs) develop the data literacy skills needed for effective data use. However, little is known about the ways in which EPPs work towards building PSTs’ data literacy, despite licensure and accreditation requirements compelling EPPs to do so. In this study, we analyzed survey, document, and interview data from Virginia EPPs to determine what present practices for DIDM preparation are taking place across the state. Results point to a lack of uniformity among EPPs for how preparation is undertaken, and that PSTS seem to have limited coursework on data use. Additionally, there appears to be minimal collaboration between EPPs and clinical partners, such that PSTs infrequently have opportunities to engage in DIDM during field experiences.

Published: October 2024

The awareness, attitudes, and practices of mothers regarding rheumatic fever (RF) remain obscure, therefore, this study aimed to assess the level of awareness, attitude, and practice of mothers regarding RF. A Quasi-experimental study was conducted on 100 mothers who visited medical centers in Yazd province in 2023 to evaluate the level of awareness, attitude, and practice, with the results reported after the intervention using self-made questionnaires. Statistical tests such as the Kruskal-Wallis test, T-test, One-Way analysis of variance, and Mann-Whitney were used. A significance level of P < .05 was assumed. The mean score of awareness was 6.63 (2.6) and 9.52 (2.59), attitude was 12.56 (4.75) and 17.51 (6.72) and practice was 13.97(5.52) and 19.25 (7.04) of mothers regarding rheumatic fever were before and after study, respectively. The results of mixed effects models showed that education has a significant effect on awareness ( P < .001), attitude ( P < .001), and practice ( P < .001). The mean score of attitude, practice, and awareness were increased by 2.98, 5.28, and 4.95, respectively, after the intervention. Based on the findings, it was observed that mothers have a moderate awareness of rheumatic fever (RF) despite the high burden, poor attitude, and practice. The results of the current study also demonstrate the influence of education in promoting positive practices. Effective training can have a positive impact on the awareness, attitudes, and practices of mothers.
Living within the Watershed: Managing Urban Water Supply in a Growing Metropolis
Authors: Tynan Nicola
Published: October 2024

London’s rapid population growth during the nineteenth century drove demand for larger volumes of higher-quality water. This gave rise to Parliamentary bills for large infrastructure projects to transfer water to London from outside the Thames watershed and for the transfer of private company assets to municipal management. Wales was the most frequently suggested source, as it was argued to have cleaner, softer, and more abundant water. London’s water companies favored using improved infrastructure, connected networks, and demand management. Despite substantial investment, London’s water company assets and responsibilities were transferred to the Metropolitan Water Board in 1904. Looking back in 1953, fifty years after it was formed to take over London’s water infrastructure, the Metropolitan Water Board noted that extensive acquisition of land for reservoirs and watershed protection by the water companies proved invaluable in securing a sustainable water supply for the metropolis a century later.
Improving Social Equity Within Public Organizations: Authority Differentials as Reference Points for Fostering Diversity and Inclusion Within U.S. Federal Agencies
Authors: Krause George A. , Park Jungyeon
Published: October 2024

Fostering diversity and inclusion (D&I) is a major challenge confronting the contemporary American administrative state. The asymmetric distribution of authority within U.S. federal agencies is critical for understanding employee perceptions of agency D&I efforts. Leveraging data from approximately 2.51 million U.S. federal employees across 105 agencies between 2010 and 2019, the statistical evidence demonstrates that authority differentials, reflected by the relative gender and racial balance of supervisory and non-supervisory personnel within U.S. federal agencies, predict employees’ evaluations of agency efforts at fostering D&I. Although these authority differentials have similar effects on employee D&I evaluations for both men and women, minority employees exhibit more sanguine assessments of agency D&I efforts than compared to non-minority colleagues predicated on such authority differentials. The statistical relationship between authority differentials and employees’ agency D&I evaluations is most pronounced for women minority employees, as well as for those holding supervisory positions.

Achieving energy and resource efficiency, cost reduction, short process chain of manufacturing and long life for tools and products are some of the benefits of using thin film coatings. This technology significantly contributes to strengthening all three pillars, that is, environment, economy and society of sustainability. This special issue aims to highlight some of the critical application areas of thin film coatings under sustainable manufacturing, focusing on machining.
What sustains feminized part-time work at the gender equality frontier? Evidence from a vignette experiment
Authors: Helgøy Anna
Published: October 2024

Feminized part-time work has been deemed a family policy conundrum yet to be solved by any welfare regime. To identify ways forward, this article examines structural drivers of part-time work decisions through a vignette experiment fielded in the gender-egalitarian context of Norway ( N = 3500). Six theory-grounded factors are tested in this multidimensional, causal framework: partner income level, physical and cognitive household labour burdens, the presence of a part-time culture at the workplace, and consequences of part-time work for career advancement and future pensions. Results show that overall, factors that regulate individuals’ material self-interest (partner income, career and pension consequences) have the largest impact on working-time decisions. Additionally, a priming treatment is given with a split sample concerning the factor of cognitive household labour – the organizational dimension of household work. Results from sub-group analyses show that non-primed respondents prefer significantly higher working hours when their cognitive labour burden is lower. Respondents who received experimental priming, however, portray the opposite behaviour (lower working-hour preference when cognitive labour burden is low). The pattern is driven by women, whereas men are left largely unaffected by both the priming and vignette treatment of cognitive labour. Thus, robust findings imply that gender inequality in material circumstances sustains feminized part-time work patterns. Suggestive evidence further indicates that gender inequality in cognitive labour loads may also contribute to sustaining feminized part-time work.
Artificial Intelligence and Political Deepfakes: Shaping Citizen Perceptions Through Misinformation
Authors: Momeni Mina
Published: October 2024

In the post-truth age, political conspiracies circulate rapidly on social media, cultivating false narratives, while challenging the public’s ability to distinguish truth from fiction. ‘Deepfakes’ represent the most recent type of misinformation. They display deceitful representations of events to lead audiences to believe in fabricated realities. There has been limited research on deepfakes in political communications. As this technology progresses, deepfakes look deceptively authentic; thus, it is necessary to explore their effects on public perceptions. This study examines viewers’ comments on an Instagram-published deepfake video of Hillary Clinton to understand the impact of this technology. The results demonstrate that individuals struggle to identify deepfake videos and that their opinions are affected by this persuasive type of misinformation. This study also explores different ethical concerns posed by political deepfakes. By offering insights into public reactions to manipulated content, this study contributes to our understanding of the political effects of AI-fabricated content.
Nurse-Led Medication Management for Older People in Home Care: A Systematic Review of Evolving Nurse Responsibilities in Technology-assisted Care
Authors: Vaismoradi Mojtaba , Lillo Crespo Manuel , Turjamaa Riitta
Published: October 2024

Technology-assisted care is transforming the home care landscape for older people requiring medication management. With evolving roles and responsibilities, nurse-led interventions are shaping the future of nursing practice in home care. This review aimed to identify and describe nurse-led roles in medication management in home care for older people within the context of technology-assisted care. A systematic review employing an integrative approach was conducted on the PubMed (covering MEDLINE), Scopus, CINAHL, ProQuest, and Embase, targeting studies published in English over the past decade, from 2014 to 2024. The initial database search identified 1629 studies, which were subsequently narrowed down to 20 studies selected for data analysis and narrative research synthesis. The review findings were classified into 3 categories: “fundamental principles,” “nurses and their role identities,” and “enhanced care quality and medication safety.” Given the effectiveness of nurses as leaders in technology-assisted home care for enhancing medication management safety, it is essential to implement policies that support and improve their involvement in multidisciplinary healthcare teams. Additionally, continuous education and training focused on technology-assisted care competencies are necessary to ensure nurses are well-prepared to enhance patient safety in home care.
Nonlinear vibro-acoustic analysis of an axially moving submerged circular cylindrical shell
Authors: Orafa Amir Hossein , Jalili Mohammad Mahdi , Fotuhi Ali Reza
Published: October 2024

In this study, the nonlinear vibro-acoustic dynamics and stability of doubly-clamped axially moving cylindrical shell are investigated. The exterior surface of the shell is in contact with fluid and subjected to oblique incident plane sound wave. Donnell’s nonlinear shallow shell theory is used to derive the nonlinear partial differential equation of the cylindrical shell for the radial motion. The Galerkin method is employed to discretize the equations of motion into the set of coupled nonlinear nonhomogeneous ordinary second order differential equations. Considering both driven and companion modes, Multiple Scales Method is used to obtain the response of the system. The effects of sound level, incident angle and axially velocity on the frequency response of the system are studied. The results show that, with increase in the shell velocity transmission loss of the circular shell increases. In addition, at low shell axial velocities simultaneous excitation of the driven and companion modes occurs.
The Help-Seeking Behavior of Victims of Image-Based Sexual Harassment and Abuse: A Scoping Review
Authors: Pijlman Valérie , Waardt Mijke de , Schoonmade Linda , Eichelsheim Veroni , Pemberton Antony
Published: October 2024

Image-based sexual harassment and abuse (IBSHA) has recently gained scientific attention. To date, research has primarily focused on victim characteristics and impact, while little specific empirical research exists on victims’ help-seeking behavior, including barriers and facilitators to seeking support. The aim of this scoping review was to examine the current state of literature on IBSHA victims’ help-seeking behavior and barriers and facilitators to seeking support. Seven electronic bibliographic databases were searched up to June 2023 to identify relevant literature. Inclusion criteria consisted of (1) English or Dutch language, (2) original empirical data, (3) studying one or more forms of IBSHA, (4) victim sample, and (5) addressing help-seeking behavior, and/or factors encouraging or discouraging help-seeking. The scoping review was conducted following the Preferred Reporting Items for Systematic Reviews and Meta-Analysis Protocols extension for scoping reviews. In total, 81 articles were included. Varying definitions of IBSHA, sample sizes, and populations complicated the drawing of general conclusions. The research was primarily conducted in English-speaking Western countries with a majority of young, White, heterosexual, and women samples. Prevalence rates of help-seeking strongly varied. Multiple sources of informal and formal support were identified, including friends, family, social media platforms, and police. Informal support appeared preferred. Articles identified several barriers to help-seeking including shame, (fear of) negative social responses and negative expectations of formal support, and facilitators, including desire for justice and takedown of non-consensually shared images. Research on IBSHA is growing rapidly. The field would benefit from further research focused on help-seeking with diverse samples, standardized measures, and intersectionality. Recommendations for policy and practice are provided.
Creating a School Leadership Culturally Responsive Special Education Climate Through the Inclusion of Student Voice in Time of Transitions
Authors: Johnson Rachelle M. , Hernández-Saca David , Cannon Mércédes Adell
Published: October 2024

We center the voice of Dwyan Moore, a Black 12-year-old boy, during his transition of being diagnosed with a learning dis/Ability. We do so to grapple with the problem of disproportionate representation in special education along race and dis/Ability, with particular attention to educational leadership. Disproportionate representation is a reminder of the legacies of slavery and eugenics in United States public schools. We must address this enduring inequity. How we think, feel, and discuss such issues has systemic educational and equity implications for Black, Indigenous, and Youth of Color with dis/Abilities such as Dwyan. We end by promoting critical reflection and activities among educational school leaders on how student voices and agency can be included in dis/Ability transition planning and programming.
Unpacking Evaluative Meaning-Making Resources in Verbal Movie Descriptions: A Comparative Study of Native and Non-Native English Speakers
Authors: Parviz Muhammed , Jalilifar Alireza , Don Alexanne
Published: October 2024

The present study explored how native speakers (NSs) and non-native speakers (NNSs) of English exploit evaluative meaning-making resources of English when sharing their judgements and opinions on English movie descriptions. To this end, 10 native speakers of Australian English and 10 Iranian non-native speakers took part in on-line informal interviews, based on an approach known as snowball sampling. The study employed a combination of both qualitative and quantitative methods of analysis. The results revealed significant differences in the use of evaluative language between the two groups, with NNSs focusing more on Affect, Judgment and Appreciation respectively, while NSs prioritized Appreciation, followed by Affect and Judgment. The findings are discussed by reference to cultural and linguistic differences in the use of evaluative resources. Moreover, NSs relied more on invoked evaluation whereas NNSs showed a preference for inscribed evaluation. However, both groups utilized a higher frequency of positive descriptions in during their descriptions of English movies. These findings can provide valuable insights for language teaching and research, highlighting the significance of incorporating evaluative language resources into language instruction. The study further brought attention to the interconnectedness of diverse evaluative resources such as reference to emotions and judgements with complex linguistic and cultural domains.

Published: October 2024

COVID-19 has caused psychological trauma. However, it is unclear whether these stresses are comparable across ethnicities, across age groups, and vaccination hesitancy. Moreover, the relationship between the different types of stresses and their relationship to vaccination hesitancy has not been studied. Using rigorous statistical methodology (structural equation modeling), we examined the measurement invariance of five COVID stress factors: danger of contamination, socioeconomic consequences, xenophobia, traumatic stress, compulsive checking, by ethnicity and age, and investigated their relationship to vaccination hesitancy, ethnicity, age, and expectations of contracting COVID using structural equation models on a UK sample. The instrument showed measurement invariance both with respect to ethnicity and vaccination hesitancy. Subjects with more stress and worry about contracting COVID had no more enthusiasm for getting vaccinated than the less stressed. Ethnic minorities were less stressed despite suffering higher morbidity and mortality. As age increases, so does the hesitancy to be vaccinated despite younger subjects reporting more compulsive checking. Vaccination hesitancy was related to fear of side effects and safety concerns. Public health campaigns should target younger populations to address their fears about and stress due to compulsive checking for COVID-19. These campaigns should also be designed to reduce vaccination hesitancy to increase vaccination rates, decrease active and passive carriers of the virus, and ultimately attain herd immunity.
The Language of Conspiracy Theories: Negative Emotions and Themes Facilitate Diffusion Online
Authors: Cosgrove Tylor , Bahr Mark
Published: October 2024

Global polling has seen an increase in endorsement of conspiratorial beliefs in recent years, with social media platforms receiving criticism for their potential role in facilitating this spread. The current study analyzed the presence of emotions and themes in conspiratorial content (revolving around conspiracy theories or conspiratorial ideas) on Twitter (now “X”) and Reddit when compared to scientific and general discussion, and the ability of emotions and themes to predict engagement (likes, shares etc.) in conspiratorial spheres. Approximately four million words worth of content were collected from Twitter and Reddit and analyzed using the Linguistic Inquiry and Word Count (LIWC) tool to determine concentration of different emotions and themes. Conspiratorial discussions were found to show significantly higher rates of anger, anxiety, power, and death compared to both scientific and general discussions across both platforms. Engagement was successfully predicted within conspiracy discussions; higher levels of anger, anxiety, power, and death predicted higher levels of engagement in conspiracy discussions. Contrary to previous findings, positive emotions were predictive of lower levels of engagement in conspiracy-related discussions. The findings suggest that conspiratorial content relies on powerful negative emotional responses to gain traction and increase audience engagement. The findings are discussed in the context of cognitive processes involved in the adoption of conspiracy theories, and we offer suggestions for researchers developing educational interventions and social media platforms to reduce the spread of conspiracy theories online.

Published: October 2024

This study investigated the effect of work engagement (WE) on teachers’ workplace well-being (WWB) and the role of perceived organizational support (POS) and psychological empowerment (PE) in the underlying internal mechanisms. The participants were 2,090 Chinese teachers (valid response rate: 90.32%), with an average age of 39.42 years ( SD = 8.73). To test the mediating role of POS and PE on the relationship between WE and WWB (parallel and serial), participants were asked to complete the subscales of employee well-being, the Utrecht Work Engagement Scale, the Psychological Empowerment Scale, and the Perceived Organizational Support Scale. The results revealed that (1) WE can positively predict WWB, (2) POS and PE mediated the relationship between WE and WWB, and (3) there were numerous indirect routes (i.e., WE→POS→PE→WWB). The results of this study help us understand the relationship between WE and WWB and have implications for improving teachers’ WWB.

The most adverse outcomes of the COVID-19 pandemic include high post-infection mortality among long-term care (LTC) home residents. Research about mortality over a longer period after contracting COVID-19 and in different pandemic years is limited. In the current study, we examined outcomes for 1,596 LTC residents from the day of a positive COVID-19 test until January 31, 2023. We reported all-cause mortality 30 days after contracting COVID-19 and monthly throughout the follow-up, up to 35 months after the pandemic start. We also examined mortality among 2,724 residents residing in the same LTC homes, with no history of COVID-19 during the same period. The results underscored a large number of deaths in the first month post-infection, with 30-day mortality substantially decreasing over the years—from 28% (95% CI [24.3, 31.8]) among residents contracting COVID-19 in 2020, to 8.3% (95% CI [7.4, 9.2]) in the 2022 cohort. Observed over longer periods, monthly mortality among residents with a COVID-19 history was similar to mortality in the No-COVID residents, and no evidence was found of increased mortality risk in the COVID group beyond the first post-infection month. We discuss mortality in LTC during the pandemic and a continuing need to reduce mortality in the acute phase of COVID-19.

Background:

Zone II and III fifth metatarsal (5-MT) fractures among athletes are typically managed with percutaneous fixation following anatomic reduction. However, screw head discomfort and refracture after bone union can occur because of the loads placed on the foot during play. Several hardware systems that use a smaller screw head compared to traditional hardware systems have been developed to minimize the rate of postoperative hardware complications. This study compares clinical and radiographic outcomes of 5-MT fractures in elite athletes treated with a solid headless screw vs a solid headed screw. We hypothesized that the headless screw would be associated with faster union rates, faster clearance times, and lower incidence of symptomatic hardware compared to the headed screw.

Methods:

Athletes competing at a collegiate level or higher treated for a zone II or III 5-MT fracture between 2016 and 2022 by 2 surgeons fellowship-trained in foot and ankle orthopaedics were screened. Operative notes were reviewed to determine the hardware system used. Subjects were divided based on the hardware system used during operation: headed screw and headless screw. Time to radiographic union, time to full clearance, and return to competition were determined. Postoperative complications, including nonunions, need for revision, need for hardware removal, and refractures were also noted.

Results:

Forty eligible patients (44 feet) were identified. The solid headed screw group included 20 patients (21 fractures), and the solid headless screw group included 20 patients (23 fractures). Average time to union for the headed screw group was 11.78 (range, 5.86-19.00) weeks; average time to union for the headless screw group was 11.65 (range, 6.00-22.57) weeks ( P = .93). Nineteen out of twenty (95%) patients were able to return to competition in both groups. Average time to return to competition for the headed screw group was 26.9 (range, 10.00-47.86) weeks, while average time for the headless screw group was 21.2 (range, 6.86-55.00) weeks ( P = .55). The overall complication rate for the headed screw was 23.8%, which was not statistically different from the overall complication rate for the headless screw of 13.0% ( P = .35).

Conclusion:

In this relatively small sample of elite athletes undergoing operative fixation of a 5-MT fracture, fixation using either a headless or headed screw system had similar good outcomes in regard to times to union, return to competition, and complication rate regardless of solid screw head type used.

Background

Inflammation is characterized by a metabolic switch promoting glycolysis and lactate production. Hexokinases (HK) catalyze the first reaction of glycolysis and inhibition of epithelial HK2 protected from colitis in mice. HK2 expression has been described as elevated in patients with intestinal inflammation; however, there is conflicting data from few cohorts especially with severely inflamed individuals; thus, systematic studies linking disease activity with HK2 levels are needed.

Methods

We examined the relationship between HK2 expression and inflammation severity using bulk transcriptome data derived from the mucosa of thoroughly phenotyped inflammatory bowel disease (IBD) patients of two independent cohorts including both subtypes Crohn’s disease (CD) and ulcerative colitis (UC). Publicly available single-cell RNA sequencing data were analyzed, and immunofluorescence staining on colonic biopsies of unrelated patients with intestinal inflammation was performed to confirm the RNA-based findings on cellular and protein level.

Results

HK2 expression gradually increased from mild to intermediate inflammation, yet strongly declined at high inflammation scores. Expression of epithelial marker genes also declined at high inflammation scores, whereas that of candidate immune marker genes increased, indicating a cellular remodeling of the mucosa during inflammation with an infiltration of HK2-negative immune cells and a loss of terminal differentiated epithelial cells in the apical epithelium—the main site of HK2 expression. Normalizing for the enterocyte loss clearly identified epithelial HK2 expression as gradually increasing with disease activity and remaining elevated at high inflammation scores. HK2 protein expression was mostly restricted to brush border enterocytes, and these cells along with HK2 levels vanished with increasing disease severity.

Conclusions

Our findings clearly define dysregulated epithelial HK2 expression as an indicator of disease activity in intestinal inflammation and suggest targeted HK2-inhibition as a potential therapeutic avenue.

Accumulation of immune cells and proteins in the subarachnoid space (SAS) is found during multiple sclerosis and in the animal model experimental autoimmune encephalomyelitis (EAE). Whether the flow of cerebrospinal fluid (CSF) along the SAS of the spinal cord is impacted is yet unknown. Combining intravital near-infrared (NIR) imaging with histopathological analyses, we observed a significantly impaired bulk flow of CSF tracers within the SAS of the spinal cord prior to EAE onset, which persisted until peak stage and was only partially recovered during chronic disease. The impairment of spinal CSF flow coincided with the appearance of fibrin aggregates in the SAS, however, it preceded immune cell infiltration and breakdown of the glia limitans superficialis. Conversely, cranial CSF efflux to cervical lymph nodes was not altered during the disease course. Our study highlights an early and persistent impairment of spinal CSF flow and suggests it as a sensitive imaging biomarker for pathological changes within the leptomeninges.
