Introduction: Worldwide around 400 million people suffer from hearing loss. There is increasing evidence that hearing loss is a modifiable risk factor for cognitive decline. However, several risk factors for cognition are common in hearing-impaired individuals, including vestibular dysfunction, anxiety, and depression. This study aimed to explore the effect of hearing loss on cognitive functioning in older adults, considering the effects of vestibular function, anxiety, and depression on cognitive performance. Method: A cross-sectional study was performed on 42 subjects with moderate-to-severe sensorineural hearing loss (SNHL) and 42 matched normal-hearing controls. Matching was based on the following factors; sex, age, education level, level of anxiety and depression, and vestibular function. The test battery consisted of a cognitive assessment (Repeatable Battery for the Assessment of Neuropsychological Status adjusted for the Hearing Impaired [RBANS-H]), hearing assessment (Pure Tone Average and speech-in-noise testing), and vestibular assessment (video Head Impulse Test [vHIT]). Depression and anxiety were evaluated using the Hospital Anxiety and Depression Scale (HADS) and Beck Depression Inventory (BDI) questionnaires. Results: A significantly lower total cognitive (RBANS-H) score was observed in the group with SNHL compared to controls (100.93 [12.94] vs. 108.88 [10.47], p = 0.003). The difference among both groups was most pronounced in the subdomains Visuospatial/Constructional (92.90 [16.32] vs. 103.12 [12.83], p = 0.002) and Attention (96.62 [12.52] vs. 104.02 [11.81], p = 0.007). The other subdomains Immediate Memory, Language, and Delayed Memory did not differ significantly between the groups with SNHL and the normal-hearing controls. Conclusion: The results of this study indicate that hearing loss negatively affects cognitive functioning, even in older adults with normal vestibular function.

Introduction: Atopic dermatitis (AD) is a chronic inflammatory skin disease, placing a significant burden on patients’ quality of life (QoL). The validated Atopic Dermatitis Control Tool (ADCT) is recommended to assess AD control in adults. The aim of this study was to assess AD control and explore associations with demographic characteristics, patient-reported outcome measures (PROMs), and treatment. Methods: In this cross-sectional study, questionnaires were sent to 2,066 adults from two tertiary referral centers who had previously physician-diagnosed AD and had visited the outpatient clinic at least once between 2020 and 2022. Questionnaires were completed between May and October 2022. AD control was assessed by the ADCT, with a score ≥7 indicating uncontrolled AD. AD severity, QoL, and weekly average pruritus were simultaneously measured using the Patient-Oriented Eczema Measure (POEM), Dermatology Life Quality Index (DLQI), and numeric rating scale (NRS), respectively, with higher scores indicating more severe symptoms. Moreover, treatment-related questions were included. Associations between uncontrolled AD, age, sex, and treatment were explored using multivariate logistic regression analysis. Results: In total, 863 patients (41.8%) filled out the questionnaire and 812 were included in the analysis, of which 59% reported controlled AD. Uncontrolled AD was associated with higher PROM scores and receiving topical anti-inflammatories only (adjusted odds ratio [95% confidence interval] ranged from 1.33 [0.995–1.88] to 2.55 [2.21–2.86]). Of those treated with topical anti-inflammatories only, 54% reported uncontrolled AD. Conclusion: The majority of the patients reported controlled AD. Patients with uncontrolled AD often reported more severe symptoms and were more likely to receive topical anti-inflammatories only. It could be considered to shift patients with uncontrolled AD from topical to systemic treatment.

Authors: Gupta Aditya K. , Taylor Daniel
Published: October 2024

Introduction: Autologous platelet-rich plasma (PRP) technologies offer an attractive treatment option for various medical fields. Owing to its high concentration of growth factors, PRP has been posited to induce proliferation, differentiation, and angiogenesis at the cellular level, as well as wound-healing and remodeling at the tissue level. The goal of the present bibliometric analysis was to characterize the growing body of literature concerning PRP use in various medical applications. Methods: A comprehensive literature search was performed on June 28, 2024, using Web of Science and SCOPUS databases, covering all available publications in selected categories from 2001 to present. Results: PRP use for hair restoration had both the greatest number of total publications among the investigated applications, whereas PRP use in dental procedures had the longest-standing history of publications. PRP use in hair restoration and facial rejuvenation had the greatest number of placebo-controlled and double-blinded randomized controlled trials; however, the impact of results may suffer from a lack of consistency in PRP preparation and outcome measurement between different studies. Conclusion: To effectively validate the utility of PRP across various medical interventions, careful consideration of methodology should be undertaken for future studies to ensure validity of results.

Published: October 2024

Introduction: Neurolymphomatosis (NL) is a rare condition characterized by the infiltration of malignant lymphoma cells into the peripheral nervous system. The optimal treatment for NL remains unclear, and patients with secondary NL have a poor prognosis. Although early recognition of NL may contribute to successful treatment, the predictive factors for secondary NL are yet to be established. Case Presentation: Here, we present our investigation on the predictive factors for secondary NL, and report two cases of secondary NL with a literature review. We analyzed chromosomal abnormalities in patients with secondary NL and found a common deletion of chromosome 10 and add(11)(p11). The chromosomal abnormalities might be a predictive factor for secondary NL; therefore, confirmation of chromosomal abnormalities can possibly give a hint for early detect of secondary NL. Prompt histopathological examination or imaging techniques can lead to early diagnosis of secondary NL in patients with diffuse large B-cell lymphoma (DLBCL). Conclusion: When neurological symptoms manifest in patients with DLBCL and there are chromosomal abnormalities, the possible development of secondary NL should be considered.

Introduction: Hyponatremia is one of the most common electrolyte abnormalities in clinical practice. Syndrome of inappropriate antidiuretic hormone (SIADH) accounts for the majority of hyponatremia cases. In some cases, it may be challenging to find an underlying etiology. Case Presentation: We present a 76-year-old male patient with complaints of altered consciousness, disorientation, and relapsing hyponatremia. The final evaluation of hyponatremia showed a diagnosis of SIADH. As the patient’s hyponatremia was unresponsive to fluid restriction, tolvaptan was started at a 7.5 mg/day dose. Following detailed investigations to find an etiology of SIADH, sphenoidal sinusitis was detected, and sinus biopsy culture yielded Aspergillus flavus/oryzae. Voriconazole (IV 6 mg/kg loading followed by 4 mg/kg) commenced, and tolvaptan was discontinued during the follow-up. Conclusion: Fungal infections should be kept in mind after excluding other causes of central nervous system-related hyponatremia in immunocompetent individuals without alarming symptoms suggestive of malignancy.
Anaphylaxie: Das Potenzial von BTK-Inhibitoren bei der Behandlung von Nahrungsmittelallergien
Authors: Wedi Bettina
Published: October 2024

Background: IgE-mediated anaphylaxis is a potentially fatal systemic allergic reaction for which there are no currently FDA-approved preventative therapies. Bruton's tyrosine kinase (BTK) is an essential enzyme for IgE-mediated signaling pathways and is an ideal pharmacologic target to prevent allergic reactions. In this open-label trial, we evaluated the safety and efficacy of acalabrutinib, a BTK inhibitor that is FDA approved to treat some B cell malignancies, in preventing clinical reactivity to peanut in adults with peanut allergy. Methods: After undergoing graded oral peanut challenge to establish their baseline level of clinical reactivity, 10 patients had a 6-week rest period, then received 4 standard doses of 100 mg acalabrutinib twice daily and underwent repeat food challenge. The primary endpoint was the change in patients' threshold dose of peanut protein to elicit an objective clinical reaction. Results: At baseline, patients tolerated a median of 29 mg of peanut protein before objective clinical reaction. During subsequent food challenge on acalabrutinib, patients' median tolerated dose significantly increased to 4,044 mg (range 444-4,044 mg). 7 patients tolerated the maximum protocol amount (4,044 mg) of peanut protein with no clinical reaction, and the other 3 patients' peanut tolerance increased between 32- and 217-fold. 3 patients experienced a total of 4 adverse events that were considered to be possibly related to acalabrutinib; all events were transient and nonserious. Conclusion: Acalabrutinib pretreatment achieved clinically relevant increases in patients' tolerance to their food allergen, thereby supporting the need for larger, placebo-controlled trials.

Published: October 2024

Background

Chronic thromboembolic pulmonary hypertension (CTEPH) is a life‐threatening complication post‐acute pulmonary embolism (PE). The assessment of CTEPH incidence and risk factors post‐acute PE in the era of direct oral anticoagulants remains insufficient.

Methods and Results

The COMMAND VTE Registry‐2 (contemporary management and outcomes in patients with venous thromboembolism registry‐2) is a multicenter registry that recruited consecutive patients with acute symptomatic venous thromboembolism from 31 centers across Japan. The primary outcome was to demonstrate the detection rate of CTEPH after acute PE in routine clinical practice. Out of the 5197 patients with venous thromboembolism included in the COMMAND VTE Registry‐2, 2787 were diagnosed with acute PE. Following a median follow‐up duration of 747 days, 48 cases of CTEPH were detected, and the cumulative diagnosis of CTEPH in routine clinical practice was 2.3% at 3 years. Independent risk factors for the detection of CTEPH by multivariable Cox regression analysis included women (hazard ratio [HR] 2.09 [95% CI, 1.05–4.14]), longer interval from symptom onset to diagnosis of PE (each 1 day, HR 1.04 [95% CI, 1.01–1.07]), hypoxemia at diagnosis (HR 2.52 [95% CI, 1.26–5.04]), right heart load (HR 9.28 [95% CI, 3.19–27.00]), lower D‐dimer value (each 1 μg/mL, HR 0.96 [95% CI, 0.92–0.99]), and unprovoked PE (HR 2.77 [95% CI, 1.22–6.30]).

Conclusions

In the direct oral anticoagulant era, the cumulative diagnosis of CTEPH after acute PE was 2.3% at 3 years, and several independent risk factors for CTEPH were identified, which could be useful for screening a high‐risk population after acute PE.
Adaptive Clinical Trials in Stroke

Published: October 2024

Designing a clinical trial to evaluate the efficacy of an intervention is often complicated by uncertainty over aspects of the study population, potential treatment effects, most relevant outcomes, dropouts, and other factors. However, once participants begin to be enrolled and partial trial data become available, this level of uncertainty is reduced. Adaptive clinical trials are designed to take advantage of the accumulating data during the conduct of a trial to make changes according to prespecified decision rules to increase the likelihood of success or statistical efficiency. Common adaptive rules address early stopping for benefit or futility, sample size reestimation, adding or dropping treatment arms or altering randomization ratios, and changing the eligibility criteria to focus on responder patient subgroups. Adaptive clinical trials are gaining popularity for clinical stroke research. We provide an overview of the methods, practical considerations, challenges and limitations, and potential future role of adaptive clinical trials in advancing knowledge and practice in stroke.

Quantitative Finance and Information Technologies: A Comparative Analysis of Quantitative Trading and Cryptocurrency and Their Regulatory Challenges
Authors: Liu Didi
Published: October 2024

As technology has improved in the last decade, financial institutions have developed new technologies, including quantitative trading and cryptocurrency, to enhance their financial products and services. This paper first provides a brief background of quantitative trading and argues for the transactional efficiency of quantitative trading over traditional trading practices; it characterizes quantitative trading as fast and precise. Meanwhile, the study also accounts for the regulatory concerns–including data leakage and platform security–that quantitative trading firms may encounter. This study then establishes a distinction between cryptocurrency and quantitative trading–the former is money-driven, and the latter is data-driven. This paper then discusses the speculative nature of cryptocurrency and addresses its financial concerns citing the FTX collapse. Overall, this paper establishes the argument that quantitative trading supported by technological experts and facilitators offers more advantages than disadvantages compared to cryptocurrency trading. This research concludes that since quantitative trading and cryptocurrency trading are conducted without consideration for international boundaries, they offer bold financial potential as alternatives to traditional banking practices, as long as specific international financial laws are complied with.
Using Illustrated Children’s Book to Strength Fracted / Cracks Identity of (the Israeli) Children
Authors: Lea Baratz
Published: October 2024

Illustrations in children's books serve as powerful aesthetic devices to address complex emotions and ideologies, particularly in war-torn regions. These visual narratives act as catalysts for moral, value-based, and political discussions, offering a wordless medium that invites diverse interpretations based on the observer's perspective. This approach creates an open dialogue where there are no absolute right or wrong answers. Children's literature, through its illustrations, becomes a significant agent of socialization. These books impart cultural values, ideological concepts, and political behavior patterns, functioning as tools for establishing culturally responsive pedagogy. The images discussed, while originating from Israeli children's books predating the 2023 conflict, possess a timeless and universal quality that transcends their immediate context. Illustrations in children's books can either complement or diverge from the accompanying text, offering varying degrees of precision or poetic license. They carry cultural connotations that encompass symbols, traditions, beliefs, behaviors, and values unique to a particular society, conveying information beyond the apparent narrative. The inherent power of illustration lies in its ability to communicate directly with young children, often without the need for adult mediation. In preschool literature, illustrations serve multiple functions: they parallel written words, demonstrate abstract concepts, provide concrete representations of characters and settings, emphasize or contradict textual elements, and expand the narrative through visual elements not present in the text. Moreover, illustrations possess a psychological-therapeutic function, contributing to indirect treatment techniques. Like all visual representations, they embody simplified messages and shape recognition, conveyed formally and tangibly, with each element having both conscious and unconscious effects on the Therapeutic visual qualities in illustrated books aim to capture emotional nuances, intensify expressions of feeling, and convey concepts that may be challenging to express verbally. This is achieved through original solutions such as symbolism and creative visual metaphors. In conclusion, illustrations in children's books, particularly those addressing complex themes like war and fear, offer a unique and powerful medium for fostering understanding, encouraging dialogue, and providing emotional support. Their ability to transcend linguistic and cultural barriers makes them invaluable tools in shaping young minds and addressing challenging societal issues.
The Importance of Child Education in the Context of Establishing a New Nation and New Society in Bekir ÇOBANZADE’s Works
Authors: Altın Ozlem
Published: October 2024

The idea of establishing a new nation and new society reflected in Bekir Sıtkı ÇOBANZADE’s ideology and poetry is an extension of İsmail Bey Gaspıralı’s national renaissance and rebirth movement. The concept of national renaissance and rebirth initiated by the Tercüman newspaper primarily influenced the children, who represented the new society that the Crimean Tatar people, seeking to return to their roots and escape Russian imperialism, aimed to establish. The Usûl-u Cedit education system was used to transform young Tatar children into heroic Turkish and Muslim people fighting against Russian imperialism. This system strengthened the rebirth process of Crimean Tatar children who were weakened by Russian imperialism. During this process, in 1905, Çobanzade initiated the Yaş Tatar movement along with young people like Numan Celebi Cihan and Hasan Mirza Cergeyev. In his poem “Anan Kayda,” published here, he aimed to raise Crimean Tatar children under Russian imperialism into children who would fight against fate and the Russification policy within the poetics of the New Nation and New Society to be established. For the Crimean Tatar people, avoiding the loss of their true selves, the only way out is to create an enlightened and educated segment built on their ideals and national identity. Therefore, in his poems, Çobanzade created a child prototype. The most well-known of these prototypes is a girl named Esma. The poet designed the political panorama of the era through Esma. He desired to raise a new nation and new society that were free from the calamities and oppression the people were facing.
Characterization of a Large Family of Convergent Series That Leads to a Rapid Acceleration of Slowly Convergent Logarithmic Series
Authors: Gaskin Joseph
Published: October 2024

Logarithmic series are known to have a very slow rate of convergence. For example, it takes more than the first 20,000 terms of the sum of the reciprocals of squares of the natural numbers to attain 5 decimal places of accuracy. In this paper, I will devise an acceleration scheme that will yield the same level of accuracy with just the first 400 terms of that power series. To accomplish this, I establish a relationship between all monotonically decreasing sequence of positive terms whose sum converges, a positive number ρ and a differentiable function φ. Then, I use ρ and φ to define the Tφ, ρ transformations on the partial sums of any convergent series. Furthermore, I prove that these Tφ, ρ transformations yield a rapid rate of convergence for many slowly convergent logarithmic series. Finaly, I provide several examples on how to compute φ if one is given the convergent series of decreasing, positive terms.
Predicting Children’s Mental Well-Being During COVID-19 Pandemic Based on Maternal Cognitive Emotion Regulation
Authors: Dehnashi Delaram
Published: October 2024

Background: During the COVID-19 pandemic, the lack of warm, supportive, and positive relationships caused behavioral and psychological problems in children. This study aimed to predict the psychological well-being of primary school students during the COVID-19 pandemic based on parental self-efficacy and cognitive emotion regulation in mothers based on the mediating role of the parent-child relationship. Methods: The present applied research used a descriptive correlation in terms of data collection and analysis. This research was conducted on 385 cases, including students and their parents, who were selected using a random sampling method. The research instruments included the Reef's psychological well-being questionnaire (18 questions), Johnston and Mash parenting sense of competence scale, Garnefski's cognitive emotion regulation questionnaire, and Fine's parent-child relationship scale. Two psychology experts assessed the face validity of the questionnaires. Reliability of the questionnaires was measured using Cronbach’s alpha coefficients. SPSS software was used to analyze the data. Results: The average total scores of psychological well-being, parenting sense of competence, parent-child relationship, and cognitive emotion regulation were 68, 58.3, 72.1, and 61.4, respectively. Maternal cognitive emotion regulation was a significant predictor of the parent-child relationship (p< 0.01). We found that parenting sense of competence and maternal cognitive emotion regulation were able to predict students' psychological well-being through parent-child relationship during the COVID-19 pandemic. Conclusion: Increasing the level of parenting sense of competence and regulating parental emotions can improve the relationship between parents and their children.

Authors: Cai Xinyue , Jin Qinyu , Zhang Wenyu
Published: October 2024

For the development of the national economy, transportation is strategically significant. As the increasing ownership of automobiles, traffic jams are a common occurrence. Accurate prediction of traffic flow contributes to diverting traffic effectively and improving the quality of urban traffic, in turn improving the operation of the overall transportation system. The rapid development of artificial intelligence technologies, especially machine learning and deep learning, has provided effective methods for accurate prediction of traffic flow. Based on the above, in order to improve the accuracy of the prediction and to extend the application of machine learning and deep learning in the prediction of traffic flow, this study proposed a bagging-based ensemble learning model. Firstly, normalization method is used to preprocess the data. Subsequently, base prediction models including decision tree, random forest, logistic regression, convolution neural network, long short-term memory and multilayer perceptron are selected for training the prediction model, respectively. Finally, bagging-based ensemble learning method is used to integrate these base prediction models to further predict traffic flow. The results of comparison between the single base prediction models and the bagging-based ensemble learning model on the five evaluation indicators show that, for predicting the traffic flow, the bagging-based ensemble learning model outperforms the base prediction models. Meanwhile, this study explores the potential in the application of machine learning, deep learning, and especially bagging-based ensemble learning to predict traffic flow.
Tribute VS "Nanman": The Image Construction of "Magic Mirror Type"
Authors: Hong Liu
Published: October 2024

For over 2000 years, feudal dynasties throughout China have referred to southerners as the “Nanman” (means Southern Barbarian). However, the specific situation of the treatment of Nanman titles by various dynasties has not been explored. In addition, the Nanman never stopped paying tribute to the Central Dynasty. No one is involved in whether tribute can earn the respect that the dynasty deserves. Nowadays, big data technology can easily handle massive amounts of literature, and it is entirely possible to analyze the above issues from "official histories" (the 25 historical books) using the method of word frequency research. The words frequency shows that since the unification of Lingnan by Emperor Qin Shi Huang, the feudal dynasties presented a paradox to Lingnan: The products in Lingnan were coveted, and local customs were despised. "Tribute" was used to cover up the predatory nature of Kings, and "Nanman" was used to establish political, national and cultural rank. The number of "tribute" and the meaning of "Nanman" formed the "magic mirror" development relationship in the big tree of feudal autocracy until the end of the Qing Dynasty. But on the one hand, the positive factors of "tribute" were absorbed and used by the western powers to establish their own alliances. On the other hand, they also mislead the public opinion and create trouble. Although "Nanman" has been eradicated politically, the regional discrimination and cultural misreading it contains have not been eradicated and often occurs. "Tribute" ranges from Kyushu to overseas to international relations. The connotation of "Nanman" from the orientation, nation and culture, the meaning of these two words has been spontaneously changing. It is timely to clarify their relationship and help make China revive.

Published: October 2024

Background: Oncocytic adrenal neoplasms, defined by ≥90 % of oncocytic cells, are rare. The significance of oncocytic changes within an adrenal neoplasm remains unclear.

Methods: A retrospective study of adults who underwent adrenalectomy at a large center identified pure oncocytic neoplasms on final pathology (1997-2022). Neoplasms were categorized based on Lin-Weiss-Bisceglia system as malignant, benign, or of uncertain malignant potential. Analysis was performed using Fisher exact, Kruskal-Wallis tests, and Kaplan-Meier analysis.

Results: Among a total of 33 patients, 24% had benign, 36% malignant, and 39% neoplasm of uncertain malignant potential. None of the benign neoplasms recurred, while 50% of the malignant neoplasms recurred (median of 40 months). Two of 13 neoplasms initially thought to be of uncertain malignant potential recurred as distant metastatic adrenocortical carcinoma at 11 and 25 months, over a median follow-up duration of 31 months. Ki67% was available for 20 patients: median (IQR) Ki67% was 5 (1, 5) for benign, 10 (6, 15) for malignant, and 6.5 (5, 10) for neoplasms of uncertain behavior, P = 0.05. Recurred neoplasms had higher Ki67% at initial resection compared to cases that did not recur.

Conclusion: While oncocytic adrenal neoplasms are rare, a significant proportion are malignant or have malignant potential. Judicious follow-up is required for oncocytic adrenal neoplasms of uncertain malignant potential, as they can recur as metastatic adrenocortical carcinoma. Ki67% should always be obtained in cases of malignancy or uncertain malignant potential as it can predict recurrence. Larger studies are needed to evaluate the appropriate follow-up protocols for these neoplasms.

Published: October 2024

Wire Electrical Discharge Machining (WEDM) is an unconventional machining technology, widely spread in different sectors of many industries. The machining uses periodically repeating electrical impulses, which allows all materials with at least a minimum electrical conductivity to be machined. The machining tool is a thin wire that can be made of many different materials. Wire electrode material requirements vary from industry to industry. This study aimed to increase the efficiency of WEDM through an analysis of the influence of the type of wire material on the machining of Albromet W130 copper alloy. The analysis comprised a molybdenum, brass and a copper wire of a 0.25 mm diameter and a Box-Behnken design of experiment totalling 42 rounds. The design of experiment results analysis covered cutting speed, machined surfaces’ topography and morphology, and the subsurface layer condition. Furthermore, an analysis of the wire electrodes used in the experiment was carried out. The highest cutting speed was achieved using a copper wire and the lowest R a values were achieved in samples machined with a molybdenum wire.

Published: October 2024

Accurately identifying penetration status is crucial for ensuring high-quality welding. However, relying on a single sensor to monitor the welding status falls short in accuracy. Thus, a novel monitoring method that fuses sound and image is proposed for assessing the laser welding penetration status. First, a microphone and a high-speed camera are employed to collect sound and image signals during welding. Second, to overcome noise challenges in sound signal, a denoising method is proposed that utilizes Grey Wolf Optimization (GWO) to find the optimal parameters for Variational Mode Decomposition (VMD). The time and frequency domain features from the denoised sound and Local Binary Pattern (LBP) features from the image are extracted. These features constitute a high-dimensional dataset, which is reduced using Principal Component Analysis (PCA). Finally, a back propagation neural network (BPNN) is constructed for fusion monitoring. The results demonstrate that fusion monitoring achieves higher accuracy (97.9%) compared to using sound (79.9%) or image (92.3%) features independently. In comparison to other methods like K-Nearest Neighbor (KNN), Naive Bayesian (NB), Support Vector Machine (SVM), and Decision Tree, BPNN fusion monitoring achieves higher accuracies, with increases of 18.09%, 12.79%, 6.53%, and 25.84% respectively. The proposed method helps to promote the development of welding intelligence.
Bullying in Schools: Persistent Legal Challenges
Authors: Katsiyannis Antonis , Rapa Luke J. , Piotrowski Julia D. , Alexandrou Elizabeth
Published: October 2024

In 2019, about 22% of U.S. students ages 12–18 reported being bullied, with a higher percentage of female students than male students reporting victimization. Recent empirical reports indicate that students with disabilities are more likely to experience bullying and be punished for bullying. Bullying has been linked to increased risk for experiencing short- and long-term consequences for victims and perpetrators, and it may result in violations of civil rights acts. Unfortunately, despite federal civil rights acts, federal guidance issued through Dear Colleague Letters, and case law, schools still engage in practices that amount to violations of students’ civil rights and make them subject to liability. In this brief, we highlight two recent court cases involving bullying in order to illustrate persistent school failures in addressing these important concerns. Implications for practice are also considered.
Online Discourse and Gender Roles in Parenting: Evidence From Mothering.com Forums
Authors: Ghanbarian Ali , Yeilaghi Noureddin
Published: October 2024

This research investigates the reinforcement and challenge of traditional gender roles in contemporary parenting by analyzing discussion threads from the online forum Mothering.com. Drawing from West and Zimmerman's theory of “doing gender” and Connell and Messerschmidt's gender theory, the study explores how users navigate gender norms in their discussions on parenting. The analysis uncovers a nuanced relationship between adhering to and resisting conventional gender roles. While many participants uphold traditional expectations of mothers as primary caregivers and fathers as breadwinners, there is also notable advocacy for more equitable parenting practices. The results underscore both the persistence of traditional gender norms and a growing movement toward gender equality in family dynamics. This research contributes to understanding about the impact of digital platforms on discussions of gender roles in parenting while offering useful considerations for the changing perceptions about motherhood and fatherhood within the digital age.

This study explores the interplay between task repetition and task motivation in second language (L2) writing, specifically focusing on syntactic complexity, accuracy, and lexical complexity (CAL). Aligning with Dörnyei’s call to balance cognitive and affective factors in task-based language teaching (TBLT), the research involved 100 advanced mid-level learners of English as a second language (ESL) aged between 18 and 20 years. Participants completed both simple and complex argumentative writing tasks in a counterbalanced order, with a one-week interval between tasks. A perception questionnaire was administered immediately after each task performance to validate cognitive task complexity manipulations. Subsequently, participants repeated the same tasks with the same time interval, complemented by the completion of a task motivation questionnaire after each task. Written essays were collected and analysed for CAL measures. Employing a multivariate multilevel approach, the results were triangulated with self-report data. Findings indicate that task repetition significantly impacted CAL in L2 writing, with a positive moderation effect by task complexity. Additionally, task motivation enhanced syntactic complexity in both simple and complex tasks, with negligible effects on accuracy. Notably, task motivation exerted a more substantial influence on students’ repeated task performance concerning lexical complexity. The study’s results offer theoretical and pedagogical insights for TBLT researchers and L2 writing practitioners.

During high power laser welding of Inconel 740H, horizontal solidification cracks form at locations between approximately 70–80% of the weld depth. With the integration of circular beam oscillation, the laser energy density distribution and underlying thermo-mechanical conditions were altered. By coupling three-dimensional heat transfer, fluid flow, and stress modelling tools, the role that circular beam oscillation plays in the formation of the strain rates and stresses driving this cracking phenomenon was identified. While the addition of a circular oscillation pattern appeared to lower the stress levels along the solidification front, it did not eliminate the appearance of horizontal cracking. Only when the beam amplitudes reached 1.6 mm did solidification cracking disappear, but the weld depths were also significantly reduced.
Mobilising for organising?: Momentum’s distributed centralization and Labour Left strategy under Corbyn (2015–2020)
Authors: Piazzo Robin , Cerabona Domenico
Published: October 2024

The Corbyn regency of the Labour Party has been marked by an apparent paradox. On one hand, the Left proved able to activate impressive processes of mobilisation during general elections and in confrontations with intraparty adversaries; on the other, it left little if any organisational legacy, rapidly retreating to a position of low relevance shortly after Corbyn’s demise. This article aims to explain such a paradox by referring to Momentum, the collective arm of the intraparty Left, and in particular to the consequences of the organisational logic it adopted, namely distributed centralization. After proposing a novel conceptualisation of distributed centralization, the article analyses, making use of 24 interviews with Momentum activists, how Momentum innovated repertories of mobilisation while proving organisationally fragile. After relating Momentum’s organisational vicissitudes with the distributed centralization logic, this study interprets the choice for this organisational model within the Left’s intraparty strategy.

Published: October 2024

Organizations now use a variety of strategies to encourage diversity since it can result in beneficial effects including an increase in creativity and innovation. Nonetheless, the diversity of their workforces continues to present challenges and opportunities for organizations. Researchers are putting more emphasis on inclusion to improve workplaces by supporting a diverse workforce. The main goal of this study was to systematically review the existing literature to ascertain how Strategic Human Resource Management fosters inclusive workplaces inside the organization. The review process was carried out using the published articles that were taken from reputable journals’ databases for the years 2010 to 2023. After reviewing 78 published articles, finding suggest that Human Resource practitioners may concentrate on a variety of Human Resource practices and design policies across these three Human Resource practice domains to have an impact on employees’ knowledge and abilities, drive and effort, and opportunities to contribute. And also Line managers are typically seen as playing a crucial role in implementing Human Resource Management practices and enhancing an inclusive workplace. Overall, the implications of this systematic review suggest that SHRM can be a powerful tool for creating inclusive workplaces, but it requires a holistic and sustained approach that involves a commitment to diversity, leadership involvement, and conscious effort to dismantle barriers and biases. End up our systematic review by forwarding future line of research on existing literature.
‘Your Analysis Is as Useless as Your Ovaries’: Women Football Fans’ Experiences on Social Media
Authors: Doehler Steph
Published: October 2024

This article provides an original contribution to the field of sports fandom by investigating the experiences of women football supporters on X (formerly Twitter). Drawing on data from an online survey of 1624 women supporters of UK-based men’s football teams, the study examines their digital interactions, gendered challenges, and subsequent coping strategies. Significantly, this study is the first to apply and extend Pope et al.’s (2022) Model of Men’s Performances of Masculinities, offering a new theoretical perspective and refinement of the original model. Through a thematic analysis, the results reveal the gendered dynamics that shape this specific sporting environment, highlighting the crucial role of social media in facilitating football-related discussions and promoting fan communities. At the same time, the study exposes the gender-based stereotypes, abuse, and discrimination that women face when expressing their identities and opinions within male-dominated football spaces. These insights not only advance understanding of gendered interactions in sports fandom but also call for enhanced measures to ensure safer online environments for women football fans.
Analysis of data from a national micronutrient survey with a linear mixed model: estimates, predictions and lessons for future surveys

Published: October 2024

Background:

Because micronutrient deficiencies affect public health, countries monitor population status by national-scale, multi-stage, micronutrient surveys (MNS). In design-based surveys, inclusion probabilities are specified for sample units and the corresponding sample weights allow design-unbiased estimates to be made of population parameters. Corrections may be possible on departures from the design; an alternative is to use linear mixed models (LMM), with an estimated covariance structure reflecting the sampling design, to obtain model-based estimates.

Design:

The Ethiopia National Micronutrient Survey (2016) specified inclusion probabilities at enumeration area (EA) and household (HH) levels, and sample weights are provided. However, the design was not followed as it would have resulted in insufficient sampling from women of reproductive age.

Results:

Having found no evidence that sample weights were informative for target serum micronutrient concentrations (Zn), we estimated LMM parameters, with Regions as fixed effects, and the variation of individuals nested within households, households within EA, and EA within regions, random effects. We obtained LMM standard errors, Best Linear Unbiased Estimates (BLUEs) of regional means, and empirical Best Linear Unbiased Predictions for sampled/unsampled EA and HH. The probability that each true regional mean exceeded the sufficiency threshold [Formula: see text] was evaluated. The variances of BLUEs of regional means, under alternative sampling designs, were bootstrapped from LMM variance components.

Conclusions:

We demonstrate use of LMM to obtain model-unbiased estimates and predictions when surveys deviate from the original design; and the use of LMM variance components to evaluate alternative designs for further sampling, or for sampling comparable populations.
