A novel FE model for the sealing performance of aviation flare joints with multiscale factors of manufacturing and assembly
Authors: Deng Lichuan , Luo Bin , Zhang Kaifu , Cheng Hui , Lin Langkun , Liang Biao
Published: May 2024

The interfacial contact status of a joint determines the sealing performance of an aircraft hydraulic system, which is influenced by inevitable multiscale assembly errors and joint manufacturing deviations. To address these challenges, a novel geometric analysis model was heuristically created that incorporates assembly and manufacturing-related topographies to accurately estimate the initial relative assembly position of joint surfaces. A microscopic contact model was constructed using the reverse reconstruction approach based on measured surface characteristics. Combining the relative position, a multiscale finite element contact model was generated to investigate the impact of each scale topography on the contact state of the seal ring. The experimental data verified the simulated indentation findings, confirming the model's efficacy in estimating contact status and seal performance characteristics. It is found that the flare angle has a more obvious effect on the contact state of the sealing interface, and a 2° difference in angle under the same load can cause a 28.19% difference in contact area, which greatly affects the sealing performance.
Tribological performance of fatty acid, acid/amine additive mixture and ionic liquid
Authors: Shu Ju , Espejo Cayetano , Kalin Mitjan , Morina Ardian
Published: May 2024

Bio-based materials have attracted great attention from industry and academia in tribology because they are renewable, bio-degradable and easily accessible. This study aims to evaluate the efficiency of bio-based materials used both as neat lubricants and additives on friction and wear performance. The evaluated lubricants include oleic acid, a mixture containing oleic acid and dodecyl amine in hexadecane and a neat ionic liquid composed of oleic acid and dodecyl amine. The influence of the additive concentration, ratio between acid and amine, and oscillation frequency under reciprocating contacts has been investigated. Surface analysis was conducted by optical microscope, scanning electron microscopy and energy-dispersive X-ray spectroscopy, and time-of-flight secondary ion mass spectrometry. The results confirm that a small amount of oleic acid as an additive can provide limited friction reduction. Bio-based ionic liquid shows the lowest friction and wear coefficient in all testing conditions. A synergistic effect between oleic acid and dodecyl amine as an additive mixture has been observed when the two components are equimolar and the oscillating frequency is high. Time-of-flight secondary ion mass spectrometry analysis of the wear track indicates that the tribological process enhances the ionic character of the additive mixture, improving the lubrication performance.

Published: May 2024

Background:

There is wide variation in stress test utilization before major vascular surgery and adherence to practice guidelines is unclear. We defined rates of stress test compliance at our institution and led a quality improvement initiative to improve compliance with American Heart Association (ACC/AHA) guidelines.

Methods:

We implemented a stress testing order set in the electronic medical record at one tertiary hospital. We reviewed all patients who underwent elective, major vascular surgery in the 6 months before (Jan 1, 2022 – Jul 1, 2022) and 6 months after (Aug 1, 2022 – Jan 31, 2023) implementation. We studied stress test guideline compliance, changes in medical or surgical management, and major adverse cardiac events (MACE).

Results:

Before order set implementation, 37/122 patients (30%) underwent stress testing within the past year (29 specifically ordered preoperatively) with 66% (19/29) guideline compliance. After order set implementation, 50/173 patients (29%) underwent stress testing within the past year (41 specifically ordered preoperatively) with 80% (33/41) guideline compliance. In the pre- and postimplementation cohorts, stress testing led to a cardiovascular medication change or preoperative coronary revascularization in 24% (7/29) and 27% (11/41) of patients, and a staged surgery or less invasive anesthetic strategy in 14% (4/29) and 4.9% (2/41) of patients, respectively. All unindicated stress tests were surgeon-ordered and none led to a change in management. There was no change in MACE after order set implementation.

Conclusions:

Electronic medical record-based guidance of perioperative stress testing led to a slight decrease in overall stress testing and an increase in guideline-compliant testing. Our study highlights a need for improved preoperative cardiovascular risk assessment prior to major vascular surgery, which may eliminate unnecessary testing and more effectively guide perioperative decision-making.
Insights from obsolescence: The interpretive potential of skeuomorphs
Authors: Conway Steve
Published: May 2024

This paper proposes a qualitative methodological framework grounded in the interpretation of skeuomorphs. Scholarly attention to this phenomenon has largely come from the spheres of archaeology and design/technology. Drawing on Benjamin's ideas about the interpretive scope of objects, I propose that skeuomorphs reflect the social conditions of their creation and can therefore be the starting point for generating a series of contemporary sociological insights. The proposed framework is applied to two case studies for the purpose of clarification.
Linear friction welding of light metals and carbon fiber-reinforced plastics
Authors: Ito Tetsuro , Kamai Masayoshi , Morisada Yoshiaki , Fujii Hidetoshi
Published: May 2024

Light metals such as Ti and Al, and carbon fiber-reinforced plastics (CFRP) are important materials employed in the aerospace and automobile industries. In this study, a thermally conductive linear friction welding (LFW) process was developed for joining these dissimilar materials, particularly Al and CFRP. By adjusting the applied pressure of LFW, the temperature at the bonding interface can be set above the melting point and below the pyrolysis point of CFRP. This made it possible to successfully accelerate the bonding reaction while preventing the formation of defects. The obtained results form the basis for the development of LFW processes used for joining dissimilar materials.
Considerations for effective dissemination of evidence-based early intervention approaches
Authors: D’Agostino Sophia R , Frost Kyle M , Pickard Katherine
Published: May 2024

Dissemination efforts play an important role in bridging the gap between research and practice. Many evidence-based early intervention programs for young autistic children have yet to be widely disseminated to the early childhood workforce. The purpose of this letter is to discuss how packaging and branding early intervention approaches may facilitate or hinder widespread dissemination to community-based early childhood settings. To disseminate early interventions more effectively, we argue that it will be important to account for factors that are known to impact the widespread uptake within community settings.

Lay abstract

Dissemination, or the widespread sharing of information, is important for moving research evidence into community practice. Early intervention programs for young autistic children have not yet been widely disseminated to the early childhood workforce. This letter describes factors that may support or prevent dissemination to community-based settings, such as packaging and branding early intervention approaches. We argue that an increased focus on dissemination research is needed.
Regulating mobility through detention: Understanding the new geography of control and containment at the Southern European border
Authors: Campesi Giuseppe
Published: May 2024

The aim of this article is to describe the evolution of immigration detention policies at the Southern European border. This will be done by presenting original data on the actual functioning of immigration detention in Italy in the wake of the so-called “refugee crisis”. By shedding light on these developments, the article reveals a notable convergence of first reception and return policies, which in turn is driving a transformation of the landscape of immigration detention leading to a proliferation of detention regimes and spaces of containment. Drawing on the literature on carceral geographies, this development is analyzed within the framework of Italy's distinct role in the geopolitics of EU border control policies. The article ultimately suggests that the immigration detention system has gradually been co-opted by the border control infrastructure, becoming part of a broader and intricate control assemblage whose essential function is the regulation of human mobility.
Enhancing the interfacial bond performance of engineered cementitious composites and concrete
Authors: Huang Jincan , Hou Wei , Li Zhiqiang , Liu Yang , Zhang Yixin
Published: May 2024

This study aims to investigate the influence of different surface treatments, including smooth interface, rough interface, anchor bolt connection, and epoxy bonding agent, on the shear resistance of Engineered Cementitious Composites (ECC)-concrete interface through bi-surface shear testing. The experimental results show that the interfacial shear strength between ECC and concrete is significantly enhanced by the implementation of the three interface treatment methods, as opposed to the smooth interface. Among these methods, the anchor bolt connection exhibits the greatest improvement in interfacial bonding performance. Notably, cohesive failure is observed in the anchor bolt connection method, while the other three methods result in adhesive failure, with only the anchor bolt connection method displaying ductile failure behavior. Following a comprehensive review of relevant studies and the outcomes of this experiment, three distinct interface bonding mechanisms were identified and the forces contributing to the bond were analyzed. Results indicated that the interfacial bond strength is notably influenced by the surface roughness. These research findings substantiate the viability of utilizing the anchor bolt connection method, particularly in applications where ductility requirements in the repair layer are essential for structural integrity.
Performance evaluation and FRP strengthening of concrete-filled steel tubular columns subjected to vehicle impact
Authors: Hu Bo , Wang Hai-Bo
Published: May 2024

Concrete-filled steel tubular (CFST) columns have been widely used in multi-story and high-rise frame structures. During the service period, they may suffer vehicle impact due to traffic accidents or terrorist attacks. This paper numerically evaluates the performance of CFST columns under vehicle impact and investigates the effects of carbon FRP (CFRP) wrapping arrangements on performance improvement of the columns. Before that, a numerical model was developed to simulate the responses of CFST columns without and with FRP wrapping under vehicle impact and post-impact axial compression, and then calibrated by reported tests. Evaluation results show that the performance of CSFT columns under vehicle impact is divided into five levels, i.e., no repair required, rapid repair required, minor repair needed, major repair needed, and replacement needed. The performance level decreases with the increase in the vehicle weight or speed and increases with the increase in the column diameter or steel tube thickness. The column height has little effects on the performance level. A higher axial load ratio, e.g., 0.5, might reduce the performance level. Besides, a CFST column tends to fail in flexure mode when hit by F800 medium truck, while it may fail in flexure & shear mode when hit by C2500 pickup truck. Investigation results indicate that FRP wrapping with each layer orientation of 90° (i.e., in the longitudinal direction) and 0° (i.e., in the hoop direction) present the best performance improvement for a CFST column possibly undergoing flexure & shear and flexure failure, respectively. The increase of the number of FRP layers effectively improves the performance levels of CFST columns but the excessive demand may be not economical. It is not necessary to employ an FRP wrapping range of 100% for improving the vehicular impact performance level of a CFST column to the expected one.
Preventing deviant behaviours in the formulation and implementation of environmental health policies in the era of self-media
Authors: Che Wanyu , Yang Yiwen , Yang Chenghu
Published: May 2024

National health could significantly impact political, economic and social spheres, having a critical role in national development, social stability and sustainable economic growth. The Chinese government is prioritizing health in all policies and promoting environmental health work. However, deviations in the implementation of China’s environmental health policy, such as excessive or incomplete execution, could hinder progress. Studies have identified the main factors that are inhibiting effective policy implementation; these include incomplete grassroots policy mechanisms, cognitive biases amongst policy executors, varying acceptance of policy execution objects and environmental complexity. To mitigate these issues, several actions have been recommended including improving government mechanisms, enhancing technical support, developing talents, increasing public scientific literacy and considering the needs of policy executors and environmental complexity. The Internet, especially self-media platforms, can enhance policy communication, reduce information bias and foster a favourable environment for policy implementation. By using self-media’s dissemination mechanism effectively, we can strengthen public consensus and improve public scientific literacy in environmental health. This contributes to eliminating policy formulation and implementation deviations, fully leveraging the guiding role of policies and promoting the construction of a Healthy China.
Requesting another to taste: Passing food and the distribution of agency in the organization of bodily trajectories
Authors: Svensson Hanna
Published: May 2024

This paper offers an analysis of the organizational features of passing food objects as a commonplace embodied social practice to accomplish requests to another to taste food during joint cooking activities. Situated within the cognate frameworks of Conversation Analysis and Ethnomethodology, the sequential, multimodal analysis details and explains the formal features of passing food from hand to hand and from hand to mouth as distinct practices with distinct micro-sequential organizations. The study draws on a corpus of 14 hours of video-recordings of naturally occurring joint cooking activities in which the participants speak German, Swedish, and English. Focusing on the projectable aspects of bodily trajectories, the analysis reveals how the request sequences are achieved through the participants’ early projection of how to pass the food objects and their stepwise mutual adjustments to their conjoint action trajectory. In progressively establishing who does what next and how during the food transfer, the participants orient to the relevance and distribution of interactional agency. When the normative organization of the step-by-step transfer is disregarded, an ambiguity emerges concerning what action the practice is doing, which prompts the participants to engage in significant interactional work to re-negotiate on what terms the transfer can resume. This shows how issues of interactional agency are exerted and exhibited in and through the sequential organization of social interaction. The results contribute to, and elaborate, prior findings on requests and advances our understanding for the close attention that participants to interaction pay to the detailed aspects of multimodally formatted actions and the normative expectancies that make up to their intelligibility, reflexively elaborating each other.
Emotional labour while working with families: Potential affordances for supporting early childhood educators’ wellbeing
Authors: Dickerson Melanie Kate , Fenech Marianne , Stratigos Tina
Published: May 2024

Partnering with families is an explicit regulatory and role requirement for early childhood educators, yet the emotional labour involved is implicit and relatively unacknowledged. While research has found that complex work demands jeopardise educator wellbeing – resulting in unprecedented turnover and attrition in Australia and internationally – little research has investigated emotional labour and associated educator wellbeing in relation to partnering with families. This article argues that the limited research on educators’ emotional labour with families and its ensuing invisibility may pertain to both its positioning within social constructivist and interpretivist paradigms that render such work as naturally inherent and to conceptualisations of emotional labour theory that entrench this work in maternalistic discourses. The article positions emotional labour theory within a critical feminist lens and as a worthwhile line of inquiry to extend this body of research and disrupt maternalistic discourses that diminish educators’ skilful labour. The potential affordances pertaining to the illumination of this work as skilful for early childhood workforce policy are considered.
Divisions among the poor: A survey experiment of tax preferences in liberalizing Brazil
Authors: Berens Sarah , Bastiaens Ida
Published: May 2024

Despite globalization’s distributional impacts, we know little about (potentially differential) tax preferences of trade winners and losers, especially within social classes. We assess tax burden preferences to sustain public good provision using a vignette experiment with randomized tax instruments in the context of a liberalizing economy. More specifically, we analyze data from an original, randomized household survey of 1008 individuals in Sao Paulo State, Brazil, in 2019. We study preferences for increases in personal income, value-added, or corporate income taxes to improve funding for the universal health care system after Brazil adopts its free trade deal with the European Union. Findings reveal that the trade-losing poor support progressive taxes, whereas the trade-winning poor favor regressive instruments. By dividing the poor, globalization may create a barrier against more progressive fiscal strategies in emerging economies.
AAC Business as Usual: Clinical Practice of School-Based Speech-Language Pathologists
Authors: Brock Kris L. , LaBranch Erica , Cummings Alycia , Ogiela Diane , Binger Cathy
Published: May 2024

School speech-language pathologists (SLPs; n = 233), via survey, provided the following business-as-usual (BAU) augmentative and alternative communication (AAC) practices: (a) service delivery models, (b) treatment intensity, (c) the number of aided models provided, and (d) caseload size and knowledge. In addition to descriptive analyses, logistic regressions determined if caseload predicted the most frequently used BAU practices. Group pull-out with two, 30-minute sessions per week was used most frequently. Most SLPs provided fewer than 20 aided models per 15-minute period. Logistic regressions revealed that SLPs with larger caseloads did not utilize the group pull-out model as frequently as SLPs with smaller caseloads. As caseload size increased, SLPs were more likely to use classroom-based services. Finally, only SLPs with large caseloads were considered high-frequency modelers. Overall, this survey provides clinicians with a starting point to enhance clinical decisions until additional BAU quantitative research is conducted with children who use AAC systems.

Published: May 2024

Purpose:

The primary aim of this study was to assess the 3-dimensional flare geometry of the Gore Viabahn VBX balloon-expandable covered stent (BECS) after fenestrated endovascular aortic repair (FEVAR) and to determine and visualize BECS-associated complications.

Methods:

This multicenter retrospective study included patients who underwent FEVAR between 2018 and 2022 in 3 vascular centers participating in the VBX Expand Registry. Patients with at least one visceral artery treated with the VBX and with availability of 2 post-FEVAR computed tomography angiography (CTA) scans (follow-up [FU] 1: 0–6 months; FU2: 9–24 months) were included. The flare geometry of the VBX, including flare-to-fenestration distance, flare-to-fenestration diameter ratio, flare angle, and apposition with the target artery were assessed using a vascular workstation and dedicated CTA applied software.

Results:

In total, 90 VBX BECS were analyzed in 43 FEVAR patients. The median CTA FU for FU1 and FU2 was 35 days (interquartile range [IQR], 29–51 days) and 14 months (IQR, 13–15 months), respectively. The mean flare-to-fenestration distance was 5.6±2.0 mm on FU1 and remained unchanged at 5.7±2.0 mm on FU2 (p=.417). The flare-to-fenestration diameter ratio was 1.19±0.17 on FU1 and remained unchanged at 1.21±0.19 (p=.206). The mean apposition length was 18.6±5.3 mm on FU1 and remained 18.6±5.3 mm (p=.550). The flare angle was 31°±15° on FU1 and changed to 33°±16° (p=.009). On FU1, the BECS-associated complication rate was 1%, and the BECS-associated reintervention rate was 0%. On FU2, the BECS-associated complication rate was 3%, and the BECS-associated reintervention rate was 1%.

Conclusions:

The flare geometry of the VBX bridging stent did not change significantly during 14 months follow-up in this study. Three-dimensional geometric analysis of the flare may contribute to identify the origin of endoleaks and occlusions, but this should be confirmed in a larger study including enough patients and BECS to compare complicated and uncomplicated cases.

Clinical Impact

The three-dimensional flare geometry of the Gore Viabahn VBX BECS was assessed on the first and second postoperative CTA scans, and geometrical changes during this period were identified. For BECS that were diagnosed with a type 3c endoleak or occlusion, the BECS geometry was analyzed to detect geometrical components that were related to the complication. Geometric analysis of the flare may help to better detect and identify the cause of such complications.

This article integrates arts-based research and critical self-reflective questions through embodied questions of having lived in Ukraine and Kazakhstan at the time the war broke out in 2022: What was it like to have left Kiev with a family amid the bombing with family? How has the adjustment unfolded? How can life be meaningful today, if at all? Through a collaborative artistic interpretation of a co-produced work, we highlight the unsaid feelings and thoughts, emphasizing a decolonial response to strife, pain, trauma, and war to allow for a healing inquiry of hope through thoughtful, caring spaces to learn and deeply feel the human experience.
piR-1919609 Is an Ideal Potential Target for Reversing Platinum Resistance in Ovarian Cancer
Authors: Yan Ying , Tian Dan , Zhao Bingbing , Li Zhuang , Huang Zhijiong , Li Kuina , Chen Xiaoqi , Zhou Lu , Feng Yanying , Yang Zhijun
Published: May 2024

Purpose

PIWI-interacting RNAs (piRNAs) are a type of noncoding small RNA that can interact with PIWI-like RNA-mediated gene silencing (PIWIL) proteins to affect biological processes such as transposon silencing through epigenetic effects. Recent studies have found that piRNAs are widely dysregulated in tumors and associated with tumor progression and a poor prognosis. Therefore, this study aimed to investigate the effect of piR-1919609 on the proliferation, apoptosis, and drug resistance of ovarian cancer cells.

Methods

In this study, we used small RNA sequencing to screen and identify differentially expressed piRNAs in primary ovarian cancer, recurrent ovarian cancer, and normal ovaries. A large-scale verification study was performed to verify the expression of piR-1919609 in different types of ovarian tissue, including ovarian cancer tissue and normal ovaries, by RT–PCR and to analyze its association with the clinical prognosis of ovarian cancer. The expression of PIWILs in ovarian cancer was verified by RT–PCR, Western blotting and immunofluorescence. The effects of piR-1919609 on ovarian cancer cell proliferation, apoptosis and drug resistance were studied through in vitro and in vivo models.

Results

(1) piR-1919609 was highly expressed in platinum-resistant ovarian cancer tissues (p < 0.05), and this upregulation was significantly associated with a poor prognosis and a shorter recurrence time in ovarian cancer patients (p < 0.05). (2) PIWIL2 was strongly expressed in ovarian cancer tissues (p < 0.05). It was expressed both in the cytoplasm and nucleus of ovarian cancer cells. (3) Overexpression of piR-1919609 promoted ovarian cancer cell proliferation, inhibited apoptosis, and promoted tumor growth in nude mice. (4) Inhibition of piR-1919609 effectively reversed ovarian cancer drug resistance.

Conclusion

In summary, we showed that piR-1919609 is involved in the regulation of drug resistance in ovarian cancer cells and might be an ideal potential target for reversing platinum resistance in ovarian cancer.
USP39 Promotes the Viability and Migration of Head and Neck Squamous Cell Carcinoma Cell by Regulating STAT1
Authors: Hu Yu , Wang Yang , Hu Wenrui , Hu Chenrui , Wang Bin , Liu Congli , Deng Anqi , Shen Bing , Wu Kaile , Liu Yehai
Published: May 2024

Objective: Ubiquitin-specific peptidase 39 (USP39) plays a carcinogenic role in many cancers, but little research has been conducted examining whether it is involved in head and neck squamous cell carcinoma (HNSCC). Therefore, this study explored the functional role of USP39 in HNSCC. Method: Liquid chromatography-tandem mass spectrometry (LC-MS/MS) was used to identify differentially expressed proteins (DEPs) between the HNSCC tumor and adjacent healthy tissues. Gene ontology (GO) and Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway analyses were used to assess the functional enrichment of DEPs. Immunohistochemistry was used to detect protein expression. The viability and migration of two HNSCC cell lines, namely CAL27 and SCC25, were detected using the cell counting kit-8 assay and a wound healing assay, respectively. Quantitative real-time PCR was used to detect the expression level of signal transducer and activator of transcription 1 ( STAT1) mRNA. Results: LC-MS/MS results identified 590 DEPs between HNSCC and adjacent tissues collected from 4 patients. Through GO and KEGG pathway analyses, 34 different proteins were found to be enriched in the spliceosome pathway. The expression levels of USP39 and STAT1 were significantly higher in HNSCC tumor tissue than in adjacent healthy tissue as assessed by LC-MS/MS analysis, and the increased expression of USP39 and STAT1 protein was confirmed by immunohistochemistry in clinical samples collected from 7 additional patients with HNSCC. Knockdown of USP39 or STAT1 inhibited the viability and migration of CAL27 and SCC25 cells. In addition, USP39 knockdown inhibited the expression of STAT1 mRNA in these cells. Conclusion: Our findings indicated that USP39 knockdown may inhibit HNSCC viability and migration by suppressing STAT1 expression. The results of this study suggest that USP39 may be a potential new target for HNSCC clinical therapy or a new biomarker for HNSCC.

Treatment of intracranial aneurysms with large-diameter (≥5.5 mm) Derivo Embolization Devices, with particular focus on 7 and 8 mm diameter devices
Authors: Goertz Lukas , Zopfs David , Kottlors Jonathan , Pennig Lenhard , Schob Stefan , Schlamann Marc , Kabbasch Christoph
Published: May 2024

Objective

There are few studies on flow diverters with diameters >5 mm. We present our preliminary experience with the 5.5–8 mm Derivo Embolization Device (DED) implants for the treatment of cerebral aneurysms.

Methods

A consecutive series of 26 patients (median age: 60 years) treated for 32 aneurysms in 26 procedures was retrospectively analyzed for procedural characteristics, complications, and mid-term angiographic results.

Results

The median aneurysm size was 10.5 mm, 2 of 30 (6%) aneurysms were ruptured and 9 (28%) had a fusiform or dissecting morphology. DED implantation was performed in the internal carotid artery in 18 of 26 (69%) procedures and in the vertebrobasilar artery in 8 (31%). Device deployment failed in 1 (4%) procedure. The 7 and 8 mm implants were successfully deployed in 5 cases. Additional balloon angioplasty or stent implantation was performed in 3 (12%) cases to improve wall apposition. Complications included 1 (4%) major stroke and 2 (8%) minor strokes. Angiographic follow up at a mean of 6 months showed complete occlusion in 8 of30 (27%) aneurysms and favorable occlusion in 14 (47%).

Conclusions

The use of large diameter DEDs was safe and feasible. The mid-term occlusion rates are acceptable considering the complex subset of aneurysms studied. Further studies are warranted to define the indications for large-diameter DEDs and to evaluate their long-term efficacy.

Expanding Qualitative Interviewing for Studies Involving Adults With Different Communication Needs: Reflections on Research With People Living With Motor Neurone Disease
Authors: Wilson Eleanor , Turner Nicola
Published: May 2024

This article explores the challenges and adaptations we undertook to engage people with different communication needs, specifically those living with motor neurone disease (MND), in qualitative research interviews. While interviewing those in advanced stages of illness has raised ethical concerns, participants continue to report value in contributing to research. We reflect on our experiences of conducting qualitative interviews with people living with MND and provide guidance for researchers facing similar challenges. MND significantly impairs communication abilities, impacting speech, gestures, and facial expressions. Communication aids such as augmented and alternative communication (AAC) devices are often key tools for communication. We draw on two research studies using expanded interview techniques to accommodate these devices and provide space for participants to express their views. Interview methods were modified to cater for participant fatigue, setting and individual communication needs. While acknowledging the limitations, we explore how digital platforms, such as MS Teams and Zoom, enabled online interviews, offering advantages for both participants and researchers. Joint interviews involving participants and family members were found to be crucial, considering the interdependence of experiences in illness. Family members often aided communication and enriched data by providing context. Email interviews were another valuable method, allowing participants time to respond and consider their answers, which was particularly useful for those with limited speech. By incorporating a variety of qualitative methods and adapting approaches, we aimed to create inclusive and meaningful research experiences for individuals with different communication needs, ensuring their voices and experiences were captured effectively.
The study of anti-idiotype antibody and antinuclear antibodies (ANA) in people receiving three doses of the COVID-19 vaccine
Authors: Chegni Hamid , Babaii Hadise , Pouran Fatemeh
Published: May 2024

Introduction: The anti-idiotype network was introduced in 1974 by Niels Jerne. One of the factors that reduces the effectiveness of the vaccines is the anti-idiotype network. It should be noted that the Anti-idiotype of the antibody has the ability to bind to the receptors of the body cells to which the antigen of the first antibody binds; this causes pathological complications, especially after a longer period of time. In this study, we aim to be the first to study the presence of Anti-idiotype antibodies and ANA in people who have received three doses of the COVID-19 vaccine and check that at least 4 months have passed since the injection of their third dose.

Materials and Methods: This study was conducted on 180 people and measuring amount of Anti-RBD Anti-idiotype, Anti-Nuclear Antibody (IgG antibodies against RNP, sm RNP, smSSB/La, SSA/Ro, scl 70, centromere B, Jo1, and dsDNA antigens) and SARS-COV-Anti IgG RBD in serum by ELISA methods.

Results: In the measurement of Anti-RBD Anti-idiotype, it was found that 14 people (7.7%) of the studied subjects had Anti-idiotype antibodies and 166 (92.3%) lacked this antibody. It was found that five of the studied subjects (2.7%) had positive values for ANA (above 50 RU/ML; in 175 people (97.3), the ANA value was negative (less than 50 RU/ML). In the examination of the results related to the measurement of the quantitative amount of SARS-COV-Anti IgG RBD, it was found that all 180 people included in the study (100%) had a detectable titer of Anti-RBD antibody.

Conclusion: Many studies have shown an association between autoimmune diseases and SARS-COV-2 and MERS-CoV. Nevertheless, no studies have investigated autoantibodies in people who have injected three doses of the COVID-19 vaccine. further studies are warranted to confirm and find the causes of this difference.
“It makes me get up and want to work even harder”: Stories of education leadership pathways
Authors: Kim Elisabeth , Smith Jo
Published: May 2024

As a result of the increasing demands and the changing multi-cultural and socio-economic profile of schools, shortages of quality education leaders are a global issue. In the United States, this is particularly pernicious in urban areas, and traditional pathways to leadership positions pose an array of barriers. There is a growing need for culturally-responsive, critically self-aware social justice-oriented (CR/CSA/SJ) leaders who are better able to retain diverse teachers, more likely to stay in urban schools, contribute to higher achievement of marginalized students, and create inclusive environments. This qualitative study uses interviews to examine the leadership pathways of 72 education leaders at 28 intentionally diverse charter schools across five U.S. locations. Findings suggest that a range of motivations and experiences facilitated their pathways into leadership positions. Implications are relevant globally, at this time of increased awareness of historic societal inequities that schools can help combat.
Beyond bias: A registered examination of the validity of using line bisection to measure non-lateralised attention
Authors: Mitchell Alexandra G , Ahmad Khan Aimal , Stocks Helen , McIntosh Robert D
Published: May 2024

Line bisection is a task widely used to assess lateral asymmetries of attention, in which participants are asked to mark the midpoint of a horizontal line. The directional bisection error (DBE) from the objective midpoint of the line is the traditional measure of performance. However, an alternative method of studying the bisection behaviour, the endpoint weightings method, has been proposed. This method produces two measures of performance: endpoint weightings bias (EWB) and endpoint weightings sum (EWS). While EWB measures attentional asymmetry, it has been suggested that EWS quantifies the total (non-lateralised) attention allocated to the task. If EWS provides a valid index of non-lateralised attention, then changes in tonic and phasic arousal should systematically affect EWS. In this article, we formally tested this prediction, using time on task to manipulate tonic arousal and unpredictable auditory tones, presented simultaneously with line stimuli, to manipulate phasic arousal. Our registered analyses revealed that neither of our manipulations for tonic or phasic arousal significantly influenced EWS. Therefore, the null hypotheses cannot be rejected. An exploratory analysis of all trials and conditions revealed a significant reduction in EWS with time spent on task. However, the lack of any significant effect of the alerting tone on EWS suggests that EWS may not be a valid measure of generalised attention to the task.

The zinc(II) bis-(8-hydroxyquinoline) (Znq2) has excellent photoluminescence properties, and its fluorescence emission can be significantly quenched by Fe3+ in water. To accelerate the detection response of Znq2 to Fe3+, a luminescent metal–organic framework Znq2@ZIF-8 based on guest molecular luminescence was constructed by growing zeolite imidazolate framework-8 (ZIF-8) on the outer surface of Znq2. The results show that the prepared Znq2@ZIF-8 has an octahedral core–shell structure, a particle size of approximately 1–3 μm, an enhanced specific surface area of 1105.41 m2 g−1, and with a stable green luminescence at 495 nm. A fluorescence analytical method was developed for the detection of Fe3+ in water, the correlation coefficients were significant in the Fe3+ concentration range of 0–600 μmol L−1, and the limit of detection was as low as 3.89 μmol L−1. The spiked recoveries of tap water samples demonstrated that the method could be applied to practical applications. The mechanism of fluorescence detection is that Fe3+ participates in the competitive coordination of Znq2@ZIF-8 metal centers, leading to the collapse of the crystal structure, meanwhile, Fe3+ produces a certain degree of competitive absorption of the excitation light of Znq2@ZIF-8. This method was applied for the detection of Fe3+ in water with good selectivity, anti-interference ability, and has the potential to be used as a rapid detection method.

Introduction

Bouldering is an Olympic discipline that takes place on low-height climbing structures known as boulders. Routesetters play a critical role in bouldering; they design and set boulders to be climbed, which must be original, safe to climb and adapted to climbers’ levels. Considering the critical role routesetters play to keep the present success and ensure the future development of bouldering, the purpose of this study was to profile expert routesetters by identifying relevant key skills they possess and examining specific strategies they use when designing boulders.

Methods

Seventy-eight expert routesetters completed an online survey structured in eight sections that assessed the following: perceptual–cognitive skills; soft skills; motor skills; climbing skills; welfare; safety and difficulty; climbing holds and wall features; and climbing movement diversity and boulder styles.

Results

Among fundamental skills experts identified, most relevant to routesetters were possessing a broad climbing movement repertoire, the ability to develop several climbing strategies for one boulder, forecasting of climbing movements, climbing-specific decision-making and creativity, self-reflection, teamwork, dealing with negative feedback, technical skills and general fitness. Furthermore, most relevant specific routesetter skills and strategies appeared to encompass the ability to design boulders that account for climbers’ skill levels and safety, to adapt to the constraints of climbing gyms, to make optimal use of climbing wall features and to design versatile climbing movements.

Conclusion

The expert routesetters’ profile comprises fundamental and specific skills and strategies that enable them to design target-oriented boulders with versatile climbing movements for different levels whilst accounting for climbers’ welfare.
Delineating the discursive (de) legitimation strategies outlined by Spanish politicians in their no-confidence motion speeches
Authors: del Saz-Rubio Mª Milagros
Published: May 2024

The present study explores the discursive (de)legitimation strategies enacted by three Spanish politicians, viz., Pablo Iglesias, Pedro Sánchez, and Santiago Abascal, within the context of a no-confidence motion speech against the governing parties in the Spanish Congress in 2017 (Popular Party), 2018 (Popular Party), and 2020 (Partido Socialista Obrero Español). Using the output of a keyword search, a qualitative analysis of the concordances where these words are used is conducted to unveil the appeals most frequently employed to justify the need to file the motion and provide reasons to evict the incumbent party. Findings point to interindividual differences regarding the appeals used. Iglesias heavily relies on altruism to present his group’s project as an alternative and on implicit authorization via referencing sources that support his claims to gain the audience’s credibility. Sánchez legitimizes his actions by rationalizing his reasons for filing the motion and conveying – via implicit authorization – that the motion is triggered by the need to uphold constitutional principles. Abascal, on his part, relies on the negative association of the out-group with lexis of a moralizing nature that challenges their credibility and reputation via direct appeals to Sánchez and Iglesias while appealing to emotions and the rationalization of the motion in terms of freedom.

Published: May 2024

Public health advocacy is a fundamental part of public health and health promotion practice. However, gaps exist in the provision of public health advocacy knowledge and skill acquisition both in the tertiary environment and within ongoing professional development programmes. The Goulburn Valley Public Health Unit partnered with the Public Health Advocacy Institute to build the skills of 49 public health and promotion professionals in their regions, to enable them to lead an advocacy project that aimed to promote state-wide initiatives. This involved a series of face-to-face skills-based public health advocacy workshops and post workshop e-mentoring. Results included the creation of locally relevant public health advocacy projects and a community of practice.

Background

The purpose of this study was to systematically review the rate and time frame to return to sports in collision athletes following arthroscopic Bankart repair.

Methods

A systematic literature search based on Preferred Reporting Items for Systematic Review and Meta-Analysis guidelines, utilizing the EMBASE, MEDLINE, and The Cochrane Library Databases was performed. Manuscripts were included if they studied collision or contact athletes, reported on return to play rates or percentages, underwent arthroscopic Bankart repair, published in a peer-reviewed journal, and published in English. The study characteristics and clinical outcomes were extracted.

Results

A total of 19 studies with 1077 patients were included. Among collision athletes undergoing arthroscopic Bankart repair, the overall rate of return to sports was 89.8% (range 72%–100%). The mean time to return to sports was 5 months (range 3–6). The overall rate of returning to the same level of play was 80.8% (range 71.1%–100%). There were high return to sports rates among all collision sports. Specific return-to-play criteria were reported in most of the studies (95%), with time to return to sport being the most reported item (89.4%).

Conclusion

Although overall return to sport among collision athletes following arthroscopic Bankart repair remains high, the proportion of athletes returning to their preoperative level of play was substantially lower.
