Leveraging Administrative Data to Study the Special Education Teacher Workforce
Authors: Gilmour Allison F. , Feng Li , Theobald Roddy
Published: July 2024

Special educator shortages have threatened the provision of services to students with disabilities since the passage of the Education for All Handicapped Children Act in 1975, since reauthorized as the Individuals with Disabilities Education Act. We conducted a systematic review of studies that used administrative data to study the special educator workforce. We identified 12 studies addressing policies or practices related to the composition, distribution, or effectiveness of the special educator workforce. Together, these studies provide emerging evidence regarding policies and practices that could support the special educator workforce. We recommend that future special educator-focused research with administrative data address the composition, distribution, and effectiveness of the workforce in tandem, better attend to heterogeneity, and move from descriptive studies to studies evaluating the outcomes of specific policies.
Response Satisficing Across Online Data Sources: Effects of Satisficing on Data Quality and Policy-Relevant Results
Authors: Berry Christopher , Burton Scot
Published: July 2024

The use of crowdsourced data has become extremely popular in marketing and public policy research. However, there are concerns about the validity of studies that source data from crowdsourcing platforms such as Amazon Mechanical Turk (MTurk). Using five different online sample sources, including multiple MTurk samples and professionally managed panels, the authors address issues related to online data quality and its effects on results for a policy-based 2 × 2 between-subjects experiment. They show that survey response satisficing, as well as multitasking, is related to attention check performance measures beyond demographic differences, and there are substantial differences across the five different online data sources. The authors specifically identify segments of high and low response satisficers using a multi-item measure and show that there are critical differences in the policy-relevant results of the experiment for these segments of online respondents. Findings suggest implications for concerns about failures to replicate results in the policy and consumer well-being, business, and social science literatures. The authors offer some suggestions for attempting to reduce problematic effects of response satisficing and data quality that are shown to differ substantially across the sample sources examined.
Crescent Mastopexy With Augmentation and Hemi-Interlocking Circumareolar Mersilene Suture: An Innovative Approach
Authors: Elfieshawy Hatem
Published: July 2024

Introduction:

Safety and patient satisfaction of crescent mastopexy and concurrent primary or revisional augmentation mammoplasty is controversial owing to secondary asymmetry and potential complications involving breast tissue and the nipple-areolar complex (NAC). The primary objective of this case series was to present a new technique that can achieve anatomic integrity and natural morphology of the NAC, while avoiding complications and minimizing scarring and hypertrophic alterations.

Materials and Methods:

Using white nonabsorbable 3-0 polyester mersilene suture for tension-free closure, the procedure was completed via intradermal insertion of the needleless end of the suture into the circumareolar NAC-skin junction at the inferior segment and an interlocking purse-string or spoke-wheel configuration in the superior segment, juxtaposing the NAC and cutaneous margin, thereby redistributing the tension line from the crescent scar to a circumareolar, cranially repositioned site. Patients were followed at 24 hours, 1, 3, 6, and 12 weeks, and 6 and 12 months. Postoperative pain was patient-measured using the Visual Analog Scale (possible scores ranged from 0 to 10), and esthetic satisfaction was determined by patient surveys (scores 0-5). Follow-up visits involved evaluation of scars, nipple sensation, nipple-areolar perfusion by capillary refill, asymmetry, and hypertrophic and pigmentation changes.

Results:

Six patients (ages 32-46) underwent 2 primary procedures and 4 revisions between January 2020 and March 2023 and were chosen retrospectively based on inclusion and exclusion criteria. One revision was completed using the traditional method while the rest were completed with the new technique. Surgical times ranged from 15:34 to 17:35 minutes, with patients reporting minimal initial and postoperative pain, high patient satisfaction, and reduced scar visibility. All patients reported postoperative pain assessments as negligible initial pain on days 0 to 3 (0) and 1 to 2 on days 4 to 7, with 1 patient scoring pain as 2 to 3. Scar visibility was minimal (<0.5 mm), although 1 patient experienced 1.5 mm at 12 months. Shape of the NAC was maintained in all cases at 6 months, with 1 patient evolving to oval shape at 12 months. Patient satisfaction was scored at 4 and 5 at 6 and 12 months. No complications, scarring, or alterations in NAC shape or position were noted.

Conclusion:

This technique avoided resection of the mammary gland, achieved minimal tension and thereby preserved the crescent scar, corrected preoperative asymmetry and mild ptosis, proved superior aesthetic enhancement, and reduced complications compared with traditional methods. These promising results warrant further evaluation in a larger cohort.
Effects of Parental Childhood Maltreatment on Children’s School Adaptation: An Intergenerational Perspective Based on Envy
Authors: Zhang Ziruo , Xiang Yanhui , Li Xiaojun
Published: July 2024

Previous studies have examined the impact of maternal childhood maltreatment (CM) on children’s school adaptation (SA), neglecting the role of fathers, and the joint influence of both parents. Based on family systems theory, this study explored the intergenerational impact of parental CM on children’s SA and the mediating role of benign envy (BE) and malicious envy (ME). A total of 334 elementary school students’ BE, ME, and SA statuses and their parents’ CM, BE, and ME statuses were collected to construct the intergenerational transmission models of BE and ME for fathers, mothers, and parents, respectively. The results revealed that maltreated fathers or mothers individually exerted negative impacts on their children’s SA, but when parents acted jointly, only fathers’ CM intergenerational influence was significant. Mediation effects demonstrated that, individually, maltreated fathers indirectly affected children’s SA through children’s BE; maltreated mothers impacted children’s SA through the “mothers’ BE→children’s BE” mediating chain; however, when taking combined parental action, only mothers’ intergenerational transmission chain was significantly present. Identifying different intergenerational influence mechanisms of maltreated parents on offspring’s school adaptation broadens our understanding of the diverse parenting roles of parents. That is, fathers foster their offspring’s environmental adaptability through encouraging external exploration, while mothers enhance socialization by nurturing internal emotional development. Formulating strategies to address the emotional issues of maltreated parents, especially mothers, is crucial for mitigating the intergenerational consequences of maltreatment and enhancing the offspring’s adaptability.
Modified constitutive models and cutting finite element simulation of Ti-6Al-4V alloy at cryogenic
Authors: Lin Huaixin , Jin Gang , Luo Shaokun , Wang Guangyu , Li Zhanjie
Published: July 2024

Mastering the high strain characteristics at cryogenics and constructing an accurate constitutive model are critical for establishing a cryogenic cutting simulation of Ti-6Al-4V alloy. The traditional constitutive model is inadequate for accounting for high and cryogenic conditions. In this paper, cryogenic split Hopkinson pressure bar (SHPB) experiments are conducted, specifically for Ti-6Al-4V alloy, to develop a modified Johnson–Cook (J–C) constitutive model that incorporates the cryogenic effect. A coupled two-dimensional orthogonal finite element simulation involving temperature displacement was conducted for the cryogenic cutting of Ti-6Al-4V alloy. This simulation was performed using ABAQUS, based on a modified J–C constitutive model subroutine. It was observed that the smallest discrepancy between the simulation results and the data from ice-fixed milling experiments was just 2.12%. The modified J–C constitutive model is more adept at simulating the chip morphology under cryogenic conditions. It was also found that cryogenic machining enhances the distribution of temperature and stress within the chip. For every 5°C reduction in processing temperature, the tool temperature diminishes by more than 2%.
Novel scheme for uncertainty and disturbance estimation to control of spacecraft system with input constraint
Authors: Jamshidi Somayeh , Mirzaei Mehdi
Published: July 2024

In this paper, a novel scheme is presented to estimate the uncertainty and disturbance of the spacecraft system by a compensatory vector calculated online from the information of measured angular velocities. The compensatory vector is used in the constrained attitude control law to compensate for the perturbations of the spacecraft system. The attitude controller considering the input limitations of reaction wheels is developed by solving an optimization problem through the Karush-Kuhn-Tucker (KKT) theorem. By using noisy angular velocities in the observer design, the stochastic stability of the closed loop system under the constrained multivariable controller is demonstrated. In the results, at first, the open-loop performance of the uncertainty and disturbance observer is evaluated through computer simulations. Subsequently, the performance of the proposed controller in both constrained and unconstrained versions is evaluated. Finally, the proposed controller performance in compensating for uncertainties and disturbances is compared with the adaptive backstepping controller reported in the literature. The comparative results of two controllers show the superior performance for the proposed constrained controller in the presence of disturbances, uncertainties and input constraints. Furthermore, the proposed control system could attenuate the effect of measurement noises of angular velocities by weighting the compensatory vector in the observer design.
Role of aggregates in the forming process of tephric loess dunes distributed along the Pacific coast of eastern Japan
Authors: Tanino Kikuko , Hosono Mamoru , Watanabe Makiko
Published: July 2024

The Pacific coast of eastern Japan contains specific aeolian landforms of geomorphological interest in terms of their formation processes in humid climates and Holocene paleoenvironments. Wind erosion landforms, characterised by blowouts, were observed at the heads of coastal cliffs which consisted of marine gravel sediments, weathered volcanic ash layers (WVALs) and black soil layers (BSLs). The blowouts were accompanied by downwind tephric loess dunes. We analysed the physicochemical properties of the WVAL, BSL and dune sediment samples. The results revealed that clay and silt contents in dune sediments were 5–48% and 20–35%, respectively. The fine particles were in the form of aggregates in the WVALs, BSLs and dune sediments, with contributions from andic properties. WVAL and BSL aggregates were prone to movement in saltation, depositing into the dunes in a formation process similar to that of clay dunes in semiarid zones. The tephric loess dunes were characterised as clay dunes based on their high clay and silt contents. In addition, the dunes were characterised by durable aggregates derived from short-range-order minerals, such as allophane. The prevailing northeasterly winds caused by intense low pressures were responsible for dune formation in the study areas. Radiocarbon dating revealed two active wind periods. The first was approximately 1005–895 cal. BC to 358–281 cal. BC, and the second was 771–886 cal. AD to 1021–1155 cal. AD.
Clinical Outcomes for Arthroscopic Anterior Talofibular Ligament Repair After Suture Anchor Insertion Through the Anterolateral Portal vs the Lateral Accessory Portal
Authors: Guo Hao , Sun Nian , Zhou Qi , Chen Zhuhong , Liu Yijun , Wei Yuxuan , Zeng Canjun
Published: July 2024

Background:

Two types of suture anchor insertion pathways (anterolateral portal vs lateral accessory portal) are used in arthroscopic anterior talofibular ligament (ATFL) repair. However, it is not clear which one is the better choice. This study aims to compare the clinical outcomes of these 2 suture anchor insertion pathways when performing arthroscopic ATFL lasso-loop repair for the treatment of chronic lateral ankle instability (CLAI).

Methods:

From 2019 to 2021, patients with CLAI who underwent arthroscopic ATFL lasso-loop repair were retrospectively reviewed and divided into the anterolateral portal (ALP) group and the lateral accessory portal (LAP) group. A 1:1 propensity score matching was used to control confounding factors based on age, sex, body mass index, follow-up duration, preoperative visual analog scale (VAS) score, and Tegner score (ALP group, n = 26; LAP group, n = 26). Karlsson score, VAS score, Tegner score, operation time, anterior drawer test results, patient symptoms, and magnetic resonance (MR) evaluation of ATFL quality were used to describe the outcomes.

Results:

The patient characteristics and follow-up durations were similar between the 2 groups. After a mean follow-up duration of 28.8 ± 2.3 months, the ALP group had significantly better Karlsson score, VAS score, and Tegner score improvement than the LAP group, with fewer symptoms. Seven patients in the LAP group still had a feeling of ankle instability, and 3 of them exhibited ankle laxity.

Conclusion:

In this study, we found that inserting the suture anchor through the anterolateral portal was associated with better outcomes compared to that through the lateral accessory portal when performing arthroscopic ATFL lasso-loop repair for CLAI patients. The improvement was greater for pain relief and function and was associated with a lower frequency of subjective ankle instability.
The Role of the Flexor Hallucis Longus in the Treatment of the Painful Hallux Metatarsophalangeal Joint
Authors: Michelson James D. , Charlson Mark D. , Bernknopf Jacob W. , Carpenter Rachel L. , Brand Stephen J.
Published: July 2024

Background:

Pain in the hallux metatarsophalangeal joint (MTPJ) is very common, yet the underlying etiology remains unknown. Previous clinical research and biomechanical research has implicated stenosing flexor hallucis longus (FHL) tendonitis as a possible cause. The hypothesis of this study was that treatment solely focusing on alleviating restricted FHL excursion would be beneficial in patients with hallux MTPJ pain.

Methods:

This is a retrospective study of those treated in the Foot & Ankle Division between January 2009, and December 2018, who were diagnosed with FHL tendonitis with associated pain in the hallux MTPJ. Demographics, comorbidities, examination findings, imaging results, pain scores, treatment instituted, and outcome was obtained from the electronic medical record. The primary outcome was the improvement in the pain score (visual analog scale [VAS]). The surgical patients were included if their procedure was solely related to the FHL (posteromedial ankle release ± os trigonum resection). The decision to have surgery was analyzed by univariate and multivariable statistics using demographics, comorbidities, and clinical findings as potential factors ( P < .05).

Results:

In 75% (59 of 79 feet), nonoperative treatment of FHL stenosis resulted in a decrease in pain scores that the patients felt was satisfactory. The operative group that had an FHL release showed decreased pain in 90% (18 of 20 feet). Multivariable analysis identified the need for immobilization (OR 9.8, 95% CI 1.8-55.2, P = .009), participating in athletics (OR 8.7, 95% CI 1.8-42.2, P = .007), and higher initial VAS (OR 1.7, 95% CI 1.3-2.3, P < .001) as being associated with the decision for surgery.

Conclusion:

Previous biomechanical studies have suggested that stenosing FHL synovitis can cause increased intraarticular loading in the hallux MTPJ. The current clinical study supports this hypothesis, demonstrating that treatment focused on relieving restricted FHL excursion can ameliorate pain in the hallux MTPJ in select cases.
“There Was Blood Coming Out of Her Eyes . . .”: Emotional-Affective Agenda Setting and Disgust in the 2016 U.S. Presidential Election
Authors: Coleman Renita , Wu H. Denis
Published: July 2024

This study tracks the affective agendas in the media’s portrayals of the nonverbal behavior of the 2016 presidential candidates, and then shows how these media portrayals are related to voters’ emotional valence. It also gauges the relationship of disgust to voting intention, comparing it with anger, fear, hope, and pride, as well as other established demographic predictors and party affiliation. Findings show that valence-based emotions as conveyed via candidates’ nonverbal behaviors are associated with viewers’ emotional valence; that is, emotional-affective agenda setting has occurred. It also demonstrates that disgust predicts vote choice as well or better than anger and fear.
Health in Crisis: A Paradox of Access for Syrian Refugees and Lebanese Hosts
Authors: Fakhry Yasmine , F. Hassan Hussein , Diab Jasmin Lilian
Published: July 2024

Background:

This study examines the health security of both Lebanese citizens and Syrian refugees in Lebanon. It also assesses the readiness and resilience of the healthcare system in response to the multi-layered crisis that began in late 2019.

Methods:

A qualitative case study design was employed, utilizing 2 unstructured interviews with health experts/hospital staff, semi-structured interviews with 20 Lebanese participants and a document review. Thematic analysis was used to analyze the data.

Results:

The study found that Syrian refugees have access to health services under terms, conditions and restrictions including out-of-pocket (OOP) payment. In contrast, Lebanese citizens find traditional health guarantor systems largely ineffective, leading to high OOP costs for most healthcare services, with few exceptions. This study reveals a paradox in healthcare access within Lebanon’s fragile environment. Syrian refugees have greater access to health services, with minimal out-of-pocket (OOP) costs to a certain extent, compared to Lebanese citizens themselves who remain entrenched in inadequate health support services and poor public administration.

Conclusion:

To address this, targeted interventions and policies are crucial for policymakers and stakeholders, including the private and public sectors, local non-governmental organizations (NGOs), and the international community. Reforms are needed, spearheaded by the Ministry of Public Health (MoPH), other relevant ministries, and government payers, to refinance the traditional guarantor system and restore Lebanese citizens’ health security. Additionally, unifying health coverage across all government payers is vital.
Are there populist parties in Brazil? An analysis of Election manifestos (2010-2022)
Authors: Venturelli Gustavo
Published: July 2024

Are there populist parties in Brazil? Despite the common perception of personalistic electoral connections, the literature suggests that parties play a crucial role in legislation and voting choice. However, Brazilian parties are overlooked in populism studies. This article adds to the literature by analyzing populism in Brazilian election manifestos between 2010 and 2022. Through a man-machine content analysis application, it finds that populism is used by only a few parties, predominantly among radical left parties. The article also explores populism within mainstream parties during the 2018 elections. Despite not representing a threat to democracy due to limited influence, the existence of populist parties challenges the misconception that populism in Brazil is solely about leadership.
The transformational power of evaluation: Exploring long-term perspectives in evaluations of impacts and outcomes from the standpoint of practitioners
Authors: de Goër de Herve Mathilde
Published: July 2024

Evaluation should be part of the sustainable transition, but the transformational power of evaluation is limited by a short-term focus. This article explores long-term issues, according to evaluation practitioners, when evaluating the consequences of an initiative. A survey ( n = 282) followed by discussions with 12 evaluators investigates what is long term in evaluations of impacts and outcomes, and why it is included or not. The results identify 2 to 5 years after the implementation of an initiative as the most common long-term timeframe. The main challenges to including long-term perspectives are missing data, attribution difficulties, and the lack of resources. The main motivations are discovering particular causalities, incorporating contextual elements, and answering the demands of other actors involved in the evaluation. These findings have implications for the transformational power of evaluation: despite challenges and a long-term timeframe that is rather short compared to sustainable development issues, practitioners are positive toward long-term integration.

Published: July 2024

We have identified the most relevant and significant psychological factors in relation to COVID-19 vaccination attitudes in Ghana, Germany, New Zealand and India. This study recruited 1822 participants from the general populations of India ( n = 411), New Zealand ( n = 413), Ghana ( n = 523) and Germany ( n = 475) to participate in a cross-sectional online survey. After controlling for the country of residence, individual psychological factors played a significant role in shaping attitudes towards COVID-19 vaccination. The results also revealed strong direct predictors that explained significant portions of the variance in the COVID-19 vaccination attitudes. Positive affect emerged as the strongest contributor in Ghana (7%), while self-compassion strongly influenced COVID-19 vaccination attitudes in India (66%). Dispositional optimism was the strongest predictor in New Zealand (5%). In Germany, compassion towards others was the strongest positive predictor (2%), while psychological distress had a strong negative impact (3%). Results highlight the importance of promoting emotional well-being to enhance vaccination coverage.
Factors influencing patient-provider communication about subjective cognitive decline in people with COPD: Insights from a national survey
Authors: Stellefson Michael , Wang Min Qi , Campbell Olivia
Published: July 2024

Objective: While there is a growing body of evidence indicating a relationship between COPD and cognitive impairment, there is a gap in evidence regarding discussions of cognitive symptoms in healthcare settings. This study investigated the extent to which individuals with Chronic Obstructive Pulmonary Disease (COPD) and Subjective Cognitive Decline (SCD) self-reported confusion or memory loss with healthcare professionals. Methods: A secondary analysis of 2019 BRFSS data of US adults aged 45+ with COPD ( N = 107,204), using logistic regression to explore associations between socio-demographic and health-related indicators with discussion of cognitive symptoms with healthcare professionals. Results: Less than half (45.88%) of individuals reporting SCD discussed their cognitive symptoms with their healthcare provider. In the adjusted model, unemployed (AOR = 2.92, 95% CI: 1.70-5.02, p < .005), retired (AOR = 3.16, 95% CI: 1.37-7.30, p < .01), and current smokers (AOR = 1.73, 95% CI: 1.02-2.93, p < .05) were more likely to discuss cognitive decline with a healthcare professional than their counterparts. In contrast, males (AOR = 0.53, 95% CI: 0.32-0.86, p < .05) and binge drinkers (AOR = 0.49, 95% CI: 0.30-0.79, p < .01) were significantly less likely to do so when compared to their counterparts. Discussion: The study highlighted significant disparities in the likelihood of individuals with COPD discussing cognitive symptoms based on socio-demographic and health risk behaviors. Conclusion: Addressing gender disparities, occupational status, and personal health risks is crucial for improving patient-provider communication about SCD among adults with COPD.
Microaggression Interactions Among Healthcare Professionals, Trainees and Students in the Clinical Environment: A Mixed-Studies Review
Authors: Archuleta Sophia , Ibrahim Halah , Pereira Travis Lanz-Brian , Shorey Shefaly
Published: July 2024

This review aims to comprehensively consolidate and synthesize the existing body of empirical research on the perceptions and experiences of healthcare professionals, trainees, and students concerning microaggression interactions within diverse clinical settings. The review protocol was registered with the international prospective register of systematic reviews (PROSPERO CRD42024546443). We employed the Joanna Briggs Institute’s mixed-methods systematic review approach. Comprehensive electronic database searches were conducted across eight databases (Medline, Embase, CINAHL, PsycINFO, Scopus, Web of Science, Social Science Database, and ProQuest Dissertation and Theses) from their respective inception dates up to October 1, 2023. The selection criteria included studies reporting instances of interprofessional or intra-professional microaggressions occurring in clinical environments among healthcare professionals, trainees, and students identifying as heterosexual and without disabilities. In total, 37 studies met the eligibility criteria and were included in our review. Our analysis revealed three primary themes: Racial Microaggressions in the Clinical Environment, Gender Microaggressions in the Clinical Environment, and Religious Microaggressions in the Clinical Environment. Research must delve deeply into these experiences to better understand their long-term consequences, while policy initiatives should be designed to establish equitable, inclusive, and respectful healthcare environments. Collaborative endeavors bridging research and policy are paramount to dismantling barriers and nurturing an inclusive healthcare landscape.
A Scoping Review of Sexual Violence Events Perpetrated Against Older People
Authors: Lee Madeline , McKillop Nadine , Moir Emily
Published: July 2024

Although 9 million older adults are estimated to be victims of sexual violence and abuse (SVA) globally each year, this population is largely overlooked in criminological research. Given the known impacts of SVA, particularly for older victims, enhanced understanding of incident characteristics, and how these events unfold, is crucial to improving prevention and response. Guided by environmental criminology perspectives, a scoping review was conducted to assess the extent to which SVA events against older people have been empirically examined to gain an understanding of the immediate circumstances in which incidents occur and how this can inform early intervention and prevention. Eight databases were searched, with records included if they reported characteristics of SVA events occurring in older adulthood, were original, peer-reviewed, empirical research, and published in English. After screening 1,278 records, 33 studies were included for review. Findings demonstrate that considerable attention has been given to understanding who is involved in SVA events and what typically occurs, however, there is a dearth of information regarding when and how these crimes are perpetrated, and the situational factors influencing offending. Resultingly, prevention recommendations largely focus on actors (e.g., victims, perpetrators, witnesses), rather than the environment in which abuse occurs, emphasizing significant gaps in understanding and response to this growing issue.
The “Pre-Rotating Dilator Technique” for Optimal Endograft Orientation in Complex Endovascular Aortic Repair
Authors: Karelis Angelos , Sonesson Björn , Dias Nuno V.
Published: July 2024

Purpose:

To describe a novel technique for optimal orientation and accurate deployment of aortic endografts during complex endovascular aortic repair (cEVAR).

Technique:

After establishing the femoral access in the standard fashion, a long large-bore dilator is inserted before the cEVAR delivery system. The dilator is advanced beyond the renovisceral segment noticing the degree of axial rotation. The endograft markers are verified with fluoroscopy outside the patient in the standard way. Thereafter, the cEVAR delivery system is pre-emptively rotated by the same degree in the opposite direction than the dilator showed upon insertion. The endograft is then advanced into position with the markers ending with the markers roughly in position. Minor adjustments are done before and during deployment if needed as per standard technique.

Conclusion:

The use of long, large-bore dilator before the introduction of the aortic graft allows to proactively minimize the risk of endograft misalignment and malrotation especially in cases with challenging anatomies in both the visceral and iliac segments. This can potentially be used in all cases because it minimizes the manipulation of the delivery system and potentially increases the accuracy of endograft deployment.

Clinical Impact

This report describes a novel technique involving the use of a long large-bore dilator to predict the degree of rotation of the cEVAR delivery system during insertion and thereby enabling a pre-emptive compensation. This facilitates the precise orientation of the main aortic endograft with an easier alignment of any branches and/or fenestrations to their respective target arteries. This approach holds the potential to mitigate several of the difficulties commonly encountered with current cEVAR solutions, especially the challenges posed by small and tortuous access and severe angulation in the iliac and visceral aortic segment.
Classification and analysis of fabric types for shirts: A comparison between virtual and real fabrics
Authors: Koo Da Som , An Jae Sang , Yoon Hye Jun
Published: July 2024

The 3D virtual simulation technology is widely applied in the fashion industry tasks, including product planning such as 3D sample work, design development, marketing, and display, enabling styling of virtual models for differentiation. Achieving a digital representation of fabrics that closely resembles actual materials requires additional information obtained through experiments, beyond basic fabric characteristics like fiber content, weight, and thickness. However, research reflecting changes in fabric properties is relatively lacking. Therefore, this study aims to propose criteria for the physical characteristics of shirt fabrics and compare fit variations of virtual garments based on fabric properties to enhance the usability of virtual garment simulation. Thus, we compared and analyzed the characteristics and draping properties of shirt fabrics using two different fabric testing methods, KES-FB and CLO Fabric Kit, and investigated correlations based on each measurement device. Additionally, virtual clothing was performed based on various fabrics to compare clothing suitability. Consequently, we classified fabrics into three clusters for each measurement method and confirmed the characteristics of each cluster. Furthermore, by visually comparing the fit of shirts based on fabric properties, we observed changes in clothing pressure and deformation rate among clusters. Therefore, we believe that the results of this study can assist designers with low proficiency in 3D virtual garment production when applying virtual materials to designs. These findings are expected to be valuable for utilizing 3D virtual clothing simulations in the fashion industry for online sales and marketing, as well as in the gaming industry for avatar costume design.
Predictive control of linear time-varying model for hydraulic erecting systems based on linear expanded state observer
Authors: Ma Dong , Liu Zhihao , Gao Qinhe , Gao Lei
Published: July 2024

By analyzing the deficiencies of existing hydraulic erecting systems (HESs) control methods, this study proposes a linear time-varying model predictive control (LTV-MPC) method based on the linear extended state observer (LESO) for HESs. First, the working mechanism of HESs is methodically analyzed and the corresponding state space equations are established. Second, the LESO system is designed to estimate the current unknown real-time states. Then, the LTV-MPC is employed to evaluate and output the optimal solution of the servo voltage signal. Finally, through simulation and experiment, the effectiveness of the proposed method is confirmed and discussed. The results show that the displacement error rate of the proposed method is still lower than 0.223% under larger external disturbances, which can effectively improve the control accuracy and stability of the system compared with other methods.
Causal associations of immune cell phenotypes with migraine: A mendelian randomization study
Authors: Chai Weifang , Chai Weihao , Guo Fei
Published: July 2024

The interaction between the immune system and the brain, crucial for blood–brain barrier integrity, is a potential factor in migraine development. Although there’s evidence of a connection between immune dysregulation and migraine, a clear causal link has been lacking. To bridge this knowledge gap, we performed a two-sample Mendelian randomization (MR) analysis of 731 immune cell phenotypes to determine their causality with migraine, of which parameters included fluorescence, cell abundance, count, and morphology. Sensitivity and pleiotropy checks validated our findings. After applying a false discovery rate correction, our MR study identified 35 of 731 immune phenotypes with a significant causal link to migraine ( p < 0.05). Of these, 24 showed a protective effect (inverse variance weighting : p < 0.05, odds ratio <1), and 11 were risk factors (inverse variance weighting : p < 0.05, odds ratio >1). Although limited by population sample size and potential population-specific genetic variations, our study uncovers a significant genetic link between certain immune cell markers and migraine, providing new insights into the disorder’s pathophysiology. These discoveries are crucial for developing targeted biomarkers and personalized treatments. The research enhances our understanding of immune cells’ role in migraine and may substantially improve patient outcomes and lessen its socio-economic impact.
Influence of global/local processing on perceived colour transparency
Authors: Hine Kyoko , Saito Riku , Nakauchi Shigeki
Published: July 2024

Our cognitive processing is flexible and affected by global/local dominance in prior cognitive tasks. Similar to cognitive processing, perceptual processing, especially colour perception related to global/local processing, may be affected by prior global/local dominance; however, this possibility has not yet been assessed. Here, we examined whether prior tasks involving global/local processing influenced colour perception related to global/local processing. As colour perception is related to global/local processing, we focused on perceived colour transparency, in which a transparent layer is perceived in front of a background layer, even though these stimuli are physically in the same layer. When viewing the colour transparency stimulus, we expected that the perceived colour of a specific region, when focusing on only the local region, would differ from that when focusing on the whole image. In our study, the participants completed a global or local Navon task, followed by a colour-matching task that assessed how they saw colours using colour transparency stimuli. The degree of optical illusion (i.e., perceived colour transparency) after the global Navon task was greater than that after the local Navon task. Thus, prior global/local processing, a flexible mode of cognitive processing, influenced colour perception. This study provides new insight into perceptual flexibility, especially in colour perception.
The implementation of a collision warning system in Formula racing
Authors: Sahin Hasan
Published: July 2024

Advanced Emergency Braking (AEB) is used to reduce rear-end collisions in critical traffic scenarios. The racing environment contributes critical cases. In Formula races, critical collisions occur during cornering. Drivers may not concentrate on the boundary regions at high speeds. For this reason, an AEB system may support the drivers in such cases. On the other hand, this system is not permitted to be implemented in racing cars. Therefore, an AEB system may be implemented into the environment of the track by using several Long-Range Radars (LRR) at critical points. The originality of this study is the approach in the implementation of an AEB system into the racing environment as a collision warning system. The effectiveness of the implementation of the AEB system into the racing environment depends on the reaction time of the racing drivers. A fuzzy logic controller was proposed to control Time to Collision (TTC) during cornering according to the track geometry. The controller design was established in MATLAB/Simulink interface with the simulations in the IPG/CarMaker environment.

Background:

Irritable bowel syndrome (IBS) is a disorder of gut-brain interaction characterized by recurrent abdominal pain related to defecation and/or associated to a change in bowel habits. According to the stool type, four different IBS subtypes can be recognized, constipation predominant (IBS-C), diarrhea predominant (IBS-D), mixed (IBS-M), and undefined (IBS-U). Patients report that their IBS symptoms are exacerbated by food. Thus, it is important to find a nutritional approach that could be effective in reducing IBS symptoms.

Objective:

The present work is a post hoc analysis of the previously published DOMINO trial. It aimed to evaluate the effects of a self-instructed FODMAP-lowering diet smartphone application on symptoms and psychosocial aspects in primary care IBS stratifying the results for each IBS subtypes.

Design:

Post hoc analysis.

Methods:

Two hundred twenty-two primary care IBS patients followed a FODMAP-lowering diet for 8 weeks with the support of a smartphone application. Two follow-up visits were scheduled after 16 and 24 weeks. IBS–Symptoms Severity Score (IBS-SSS), quality of life (QoL), and adherence and dietary satisfaction were evaluated.

Results:

After 8 weeks, IBS-SSS improved in all IBS subtypes ( p < 0.0001). Physician Health Questiionnaire (PHQ-15) improved only in IBS-D ( p = 0.0006), whereas QoL improved both in IBS-D ( p = 0.01) and IBS-M ( p = 0.005).

Conclusion:

This post hoc analysis showed that the app is useful in all IBS subtypes; thus, it could be used as an effective tool by both general practitioners and patients to manage symptoms in primary care.

Comparative risk of serious infections and tuberculosis in Korean patients with inflammatory bowel disease treated with non-anti-TNF biologics or anti-TNF-α agents: a nationwide population-based cohort study
Authors: Kim Min Jee , Kim Ye-Jee , Jeong Daehyun , Kim Seonok , Hong Seokchan , Park Sang Hyoung , Jo Kyung-Wook
Published: July 2024

Background:

The risk of serious infection and active tuberculosis in patients with inflammatory bowel disease (IBD) has not been concurrently evaluated based on the use of anti-tumor necrosis factor (TNF)-α agents versus non-anti-TNF biologics (vedolizumab/ustekinumab) in the Korean population.

Objectives:

We compared the risk of serious infection and active tuberculosis in Korean patients with IBD treated with non-anti-TNF biologics (vedolizumab/ustekinumab) or anti-TNF-α agents.

Design:

This study was a population-based cohort analysis of nationwide administrative claims data.

Methods:

Health Insurance Review and Assessment Service claims data (representing 97% of the South Korean population) from between January 2007 and February 2021 were reviewed, and adults with IBD who initiated vedolizumab/ustekinumab or anti-TNF-α treatment ( n = 6123) between 2017 and 2020 were enrolled. Intergroup differences in the risk of serious infection requiring hospitalization/emergency department visits or active tuberculosis during the follow-up period were analyzed.

Results:

In the patients treated with anti-TNF-α agents or vedolizumab/ustekinumab during a mean follow-up of 1.55 ± 1.05 and 0.84 ± 0.69 years, the incidence rates of serious infection were 9.43/100 and 6.87/100 person-years, respectively. Multivariable analysis showed no significant intergroup difference in the risk of serious infection with vedolizumab/ustekinumab or anti-TNF-α treatment; the adjusted relative risk of vedolizumab/ustekinumab compared with anti-TNF-α agents was 0.81 (95% confidence interval 0.46–1.44, p = 0.478). Among patients treated with anti-TNF-α agents and vedolizumab/ustekinumab, the incidence rates of active tuberculosis were 0.87 and 0.37 per 100 person-years, respectively. The relative risk of vedolizumab/ustekinumab compared with anti-TNF-α agents was 0.31 (95% confidence interval 0.07–1.26, p = 0.101). In a subset analysis comparing vedolizumab and ustekinumab with anti-TNF-α agents, similar results were observed.

Conclusion:

In Korean patients with IBD, non-anti-TNF biologics (vedolizumab/ustekinumab) tended to be associated with a lower risk of serious infection or active tuberculosis than anti-TNF-α agents.
Is the Effect of Trust on Risk Perceptions a Matter of Knowledge, Control, and Time? An Extension and Direct-Replication Attempt of Siegrist and Cvetkovich (2000)

The complexity of societal risks such as pandemics, artificial intelligence, and climate change may lead laypeople to rely on experts and authorities when evaluating these threats. While Siegrist and Cvetkovich showed that competence-based trust in authorities correlates with perceived societal risks and benefits only when people feel unknowledgeable, recent research has yielded mixed support for this foundational work. To address this discrepancy, we conducted a direct-replication study (preregistered; 1,070 participants, 33 risks, 35,310 observations). The results contradict the original findings. However, additional non-preregistered analyses indicate an alternative perspective aligning with compensatory control theory and the description-experience framework: experiences with insufficient personal control over a threat may amplify individuals’ dependency on powerful others for risk mitigation. These findings highlight the need to reevaluate how trust shapes risk perceptions. Recent societal and technological shifts might have heightened the desire for control compared to subjective knowledge in why people resort to trust.
Patients’ perspectives on oral decitabine/cedazuridine for the treatment of myelodysplastic syndromes/neoplasms
Authors: Zeidan Amer M. , Perepezko Kate , Salimi Tehseen , Washington Terri , Epstein Robert S.
Published: July 2024

Background:

Hypomethylating agents (HMAs) are guideline-recommended treatment for higher-risk myelodysplastic syndromes/neoplasms (MDS). However, a prior survey of patients with MDS reported challenges with intravenous (IV) and subcutaneous (SC) HMA therapies, including pain related to treatment administration and interference with daily activities; most patients also indicated a preference to switch to an oral therapy if one were available.

Objectives:

This study evaluated the perspectives of US patients with MDS receiving oral decitabine/cedazuridine (DEC-C), an alternative to IV/SC HMAs.

Methods:

An online survey was conducted among adult patients with MDS in the United States (10 November 2022 to 5 December 2022) who had filled a prescription for oral DEC-C between 2021 and 2022.

Results:

A total of 150 patients completed the survey; 61% were aged ⩾60 years and 63% were male. Of these, 123 (82%) were still receiving oral DEC-C, and 27 (18%) had stopped oral DEC-C treatment. Half (50%) of patients had received oral DEC-C for ⩾6 months. The majority reported that treatment was convenient (83%) and that they were satisfied with treatment (86%). Most patients also reported very little/no interference with regular daily activities (82%), social activities (78%), and productivity (78%). When queried about negative impacts on quality of life (QOL), treatment side effects were the most commonly reported (30% of respondents). Among patients who had previously received IV/SC HMAs ( n = 91), most agreed that oral DEC-C interfered less with daily life (91%) and had experienced improvement in QOL (85%) compared with previous treatment; 91% reported that oral DEC-C reduced the number of times they needed to travel to a healthcare facility.

Conclusion:

Survey results suggest very little/no impact on regular daily activities and improved QOL with oral DEC-C relative to IV/SC HMAs, highlighting the potential for oral DEC-C to reduce the treatment burden associated with parenteral HMA therapy.
Long-acting antipsychotic treatments: focus on women with schizophrenia
Authors: Brissos Sofia , Balanzá-Martínez Vicent
Published: July 2024

Effective management of schizophrenia (SZ) requires long-term treatment with antipsychotics (APs) to prevent clinical relapse, attain remission and improve patients’ personal and social functioning, and quality of life. Although APs remain the cornerstone treatment for patients with SZ, despite their potential benefits, long-acting injectable APs (LAI-APs) remain underused, most notably in women with SZ. The efficacy and tolerability of APs differ significantly between men and women, and some of these differences are more noticeable depending on the patient’s age and the stage of the disorder. Although sex differences may influence treatment outcomes in SZ, their pertinence has been insufficiently addressed, especially regarding the use of LAI-APs. Some biological and social experiences, such as pregnancy, lactation, contraception and menopause, are specific to women, but these remain under-researched issues. Implications of this disorder in parenting are also of special pertinence regarding women; therefore, taking sex differences into account when treating SZ patients is now recommended, and improving personalized approaches has been proposed as a priority in the management of psychosis. In this narrative, critical review, we address some aspects specific to sex and their implications for the clinical management of women with SZ, with a special focus on the potential role of LAI-AP treatments.
