Effects of six antipsychotic drug treatment regimens on short-term heart rate variability in patients with schizophrenia
Authors: Huang Lifen , Wei Chaoyang , Qin Qinghua
Published: October 2024

Objective

Many antipsychotic drugs have cardiac side effects due to their pharmacological actions. Heart rate variability (HRV) analysis can be used as a potential indicator of cardiotoxicity in cases where a decrease in HRV occurs after the administration of antipsychotics such as clozapine. The purpose of this study was to explore the effects of 6 antipsychotic drug regimens on short-term HRV in patients with schizophrenia.

Methods

Data from 164 patients with schizophrenia between January 2018 and June 2023 were retrospectively analysed. Based on the drug used for treatment, the patients were categorised into clozapine combination (clozapine combined with aripiprazole, risperidone or ziprasidone), clozapine alone, olanzapine, aripiprazole, ziprasidone or risperidone groups. Heart rate variability indices were calculated using time domain analysis, including the standard deviation of the RR intervals (SDNN), the root mean square of successive RR interval differences (RMSSD) and the percentage of successive RR intervals over 50 ms (PNN50).

Results

Compared with the pretreatment period, the SDNN, RMSSD and PNN50 were significantly lower in the clozapine combination, clozapine, olanzapine and aripiprazole groups at the end of weeks 2 and 4 of treatment ( P < 0.05). However, these indicators in ziprasidone and risperidone groups did not show this significant decrease ( P > 0.05).

Conclusion

The effects of clozapine combination and clozapine on HRV were greater than for olanzapine, aripiprazole, ziprasidone or risperidone. Attention should be paid to controlling the dosage of clozapine combination and clozapine and monitoring the patient’s electrocardiogram during administration.
Influence of reservoir water saturation on coalbed methane development: Based on multi-field coupling numerical simulation
Authors: Liu Yinan , Xu Hao , Zong Peng , Wang Li , Xu Yanyong , Zhao Tiantian , Dong Yu
Published: October 2024

Water in coal reservoirs serves as both the driving force of reservoir fluid and the resistance to coalbed methane (CBM) migration. However, the impact and control mechanism of water saturation on CBM development in the field have not been revealed yet. The evolution of reservoir dynamics and gas production rate under various initial water saturation conditions is simulated based on the COMSOL multiphysics numerical simulation software. The simulation results show that the reduction of initial water saturation can significantly enhance the effective permeability of the reservoir gas phase, which can be increased by up to 4764%. This increases the rate of gas production, which is the main mechanism for controlling production by water saturation in the reservoir. For high water saturation reservoirs, the positive effect of inter-well interference should be reasonably utilized, and high well network density should be used to rapidly increase gas-effective permeability. For low water saturation reservoirs, the negative effect of inter-well interference should be avoided, and low well network density should be used to increase the control of single well reserves.
The Effect of Postural Rehabilitation on Pain, Balance, Mandibular Movement, and Posture in Temporomandibular Disorder Patients: A Comparison Between Posterior Edentulous and Dentate Groups
Authors: Narin Aral Selnur , Turedi Rubeysa , Coskun Akar Gulcan
Published: October 2024

Objective: Posterior edentulism reduces occlusal support, thus increasing the risk and symptoms of temporomandibular disorder. No previous study has explored its effect on the treatment of temporomandibular disorders. This study aimed to examine the relationship between neck posture, balance, and posterior edentulism in patients with temporomandibular disorder and compare the effectiveness of physical therapy. Methods: In a quasi-experimental controlled trial, 26 patients with temporomandibular disorder were divided into 13 in the partly edentulous group and 13 in the dentate group. Both groups received manual therapy, postural exercises, deep neck flexor stabilization, and Kinesio tapping for 6 weeks. Each participant completed 12 physiotherapy sessions, administered twice weekly, with a minimum interval of 48 hours between sessions. Outcomes were assessed at baseline and after the 6-week program, including pain, mandibular movement, posture, and balance. Results: The physical therapy program significantly improved all measured outcomes ( P < .05). Furthermore, the partially edentulous group showed more remarkable improvement in pain and balance compared to the dentate group ( P < .05). Conclusions: Postural exercises effectively alleviate symptoms in patients with temporomandibular disorder, with more significant improvements observed in the partially edentulous group than in the dentate group.
Evaluation of the Educational Quality of Endonasal Endoscopic Dacryocystorhinostomy Videos on YouTube with IVORY and LAP-VEGaS Guidelines
Authors: Bozhöyük Mitat Selçuk , Yücel Levent
Published: October 2024

Objective: The aim of this study was to evaluate the educational quality of endonasal endoscopic dacryocystorhinostomy (EE-DCR) videos on YouTube with Instructional Videos in Otorhinolaryngology by YO-IFOS (IVORY) and LAParoscopic surgery Video Educational GuidelineS (LAP-VEGaS) guidelines and to evaluate the correlation of the 2 guidelines. Methods: EE-DCR videos were queried using search terms on YouTube. Views, likes, likes/dislikes ratio, age, and length of videos were noted. Videos were evaluated using the IVORY and LAP-VEGaS guidelines. Two IVORY scores were created: total (IVORY-1) and organ-specific (IVORY-2). The correlation analysis between video features and guideline scores was performed. Results: A total of 61 EE-DCR videos were evaluated. The mean score of LAP-VEGaS was 10.3 (±SD 2.7), the mean IVORY-1 score was 22.5 (±SD 5.5), and the mean IVORY-2 score was 10.6 (±SD 1.94). Correlation analysis revealed a statistically significant correlation between the IVORY-1 total score and the number of likes, the duration of the video, the age of the video, and the LAP-VEGaS score. Linear regression analysis showed that higher IVORY-1 scores predicted longer video duration, newer video age, and higher LAP-VEGaS scores. There was a significant association between LAP-VEGaS categories and the IVORY-1 total score ( P < .001). Conclusion: The quality of EE-DCR videos is generally low to moderate. The IVORY and LAP-VEGaS guidelines were found to be correlated with each other. Both guidelines can be used to evaluate EE-DCR videos and otolaryngology surgical education videos in general. We believe that scales such as IVORY and LAP-VEGaS may be improved according to specific surgical procedures.
When Time Is the Enemy: An Initial Test of the Process Model of Patience
Authors: Sweeny Kate , Hawes Jason , Karaman Olivia T.
Published: October 2024

The process model of patience attempts to reconcile disparate approaches to understanding patience. This investigation provides an initial test of the tenets of this new theoretical model, which positions impatience as a discrete emotion and patience as a targeted form of emotion regulation. In three studies with diverse samples ( N = 1,401; data collected 2022–2023), participants responded to hypothetical scenarios designed to tap into familiar experiences of impatience. Regarding impatience, findings support our claim that impatience arises in response to the perception that a delay is unreasonable or unfair, and situational and intrapersonal characteristics emerged as predictors of impatience. Regarding patience, findings were consistent with the conceptualization of patience as driven more by intrapersonal than situational factors and revealed a set of individual differences that predicted patience. This investigation lends support to the process model of patience as a viable approach, generative of testable research questions, with implications for well-being.
Applying Implicit Propositional Measures to Detect Faking in Personality-Related Scales: Reliability, Discriminating Power, and Classification Accuracy
Authors: Dentale Francesco , Vecchione Michele
Published: October 2024

Two implicit propositional measures designed to detect faking in personality-related scales were tested across four experimental studies. Study 1 (n = 116) included the Deception Relational Responding Task and Narcissistic Admiration and Rivalry Questionnaire as the faking-detector and target scale, respectively. Respondents were randomly assigned to faking or no-faking conditions. Faking respondents were instructed to appear opposite to their narcissistic profile, while no-faking had to respond honestly. In Study 2 (n = 133), the faking-detector was the Deception Implicit Association Test (Dec-aIAT), while the target scale and faking/no-faking instructions remained the same. In Studies 3 (n = 74) and 4 (n = 111), the faking-detector was again the Dec-aIAT, while the target scale was the Big Five Questionnaire-2. Faking respondents had to adhere to a desirable target profile (Study 3; faking-good) or its opposite (Study 4; faking-bad) while no-faking should respond honestly. Overall, the implicit measures showed adequate-to-excellent reliability, discriminating power, and classification accuracy.
Shifts in Racial Inequalities and White Backlash in the 21st Century U.S.
Authors: Sarmal Apoorva , Cha Leah , Skinner Allison L.
Published: October 2024

Progress toward racial equality over the course of U.S. history has not been linear, and reductions in racial inequalities have historically been met with racist backlash. In the current research, we examine whether shifts in racial inequalities in key structural areas in recent decades can be used to predict implicit and explicit racial attitudes among White U.S. residents ( N = 222,203). Consistent with the hypothesis that increasing racial equality is threatening, the majority of the statistically significant effects we observed indicated increased pro-White attitudes among White residents of states where racial inequalities decreased over time. State-level reductions in racial inequalities related to government assistance and employment—which have both been highly politicized—were predictive of greater pro-White attitudes among White U.S. residents. Overall, the current findings provide suggestive evidence that reductions in state-level racial inequalities may threaten the status quo, heightening pro-White attitudes among White U.S. residents.
City of New York’s Cabinet for Older New Yorkers is a Model for Age-Inclusive Policy Design and Implementation
Authors: Geiling Jennifer , Shineman Meghan
Published: October 2024

The global population is aging with adults living longer and declining birth rates creating major implications for policy and infrastructure. The City of New York is cultivating an “Age-Inclusive” model that considers the needs of older adults today while laying the groundwork for tomorrow. Focused on cross-agency collaboration that approaches problem solving and design through the multi-dimensionality of every-day life, New York City Mayor Eric Adams introduced the Cabinet for Older New Yorkers (“Cabinet”) as a novel approach to imagining, designing and implementing policy, structural and systemic changes. Dozens of reforms have been developed and rolled out through the Cabinet, impacting the lives of thousands of New Yorkers across generations. The Cabinet is a model for policy design that can be replicated across cities and issue areas.
With Privilege Comes Responsibility: Why some privileged insiders transform institutions for societal benefit
Authors: Feront Cecile , Bertels Stephanie , Hamann Ralph
Published: October 2024

Why do some privileged insiders take action to transform institutions for broader societal benefit, while others do not? Privileged insiders are those who, because of their education, socio-economic background, formal position, citizenship, gender and/or race, derive advantages from existing institutional arrangements. While their relative privilege places them in a better position to influence institutions, prior research would suggest that they are unlikely to do so without the prospect of personal gain. We find that privileged insiders feel compelled to engage in prosocial institutional transformation when they situate the problem not with others but with themselves, acknowledging their own complicity in structural injustice. They can navigate the emotional discomfort triggered by moral emotions by taking small pragmatic actions that lower their emotional distress and initiate a cycle of experimentation with change. Finally, we show that the practical evaluative dimension of agency plays a central role in shaping institutional change agency. Foregrounding the role of emotions in practical evaluation, we reveal how transformative templates for action emerge from a deliberative engagement with the self.
Cultural Appreciation and Appropriation in the Crafting of the New Peruvian Cuisine
Authors: Zakrzewska Belinda , Beverland Michael , Manning Stephan
Published: October 2024

Elite craftspeople, as specialist producers with privileged access and resources, can elevate the perceived status of craft elements such as materials, traditions, and techniques regarded as lowbrow due to their association with marginalized groups. While elite craftspeople strive to emphasize cultural appreciation, they often face accusations of cultural appropriation which, if unaddressed, can undermine the perceptions of authenticity crucial for achieving higher cultural status. However, this tension between appreciation and appropriation overlooks the complex interplay of authenticity types that can structure the actions of elite craftspeople. Drawing on a qualitative study of new Peruvian cuisine, we examine how local elite chefs elevate marginalized craft elements through authenticity claims and develop a dual process model of cultural appreciation and appropriation. In doing so we identify how the elevation of marginalized craft elements involves, and even necessitates, aspects of appreciation and appropriation, especially when power dynamics are at play. We provide insights into the interplay between authenticity as connection and conformity, the agency in neo-craftwork, and claims of craftwashing.
Kuwaiti Teachers’ Classroom Behavior Management Practices, Experiences, and Beliefs
Authors: Alkherainej Khaled , Pinkney Christopher
Published: October 2024

Recent statistics suggest that student externalizing behaviors are increasing in Western and Asian countries; however, there is a paucity of research on teachers’ perspectives of these behaviors in Middle Eastern countries. A mixed-methods research design was used to investigate Kuwaiti public elementary and middle school teachers’ perceptions of their classroom behavior management (CBM) experiences, including their (a) academic preparation; (b) use of CBM practices to support students with externalizing behaviors; (c) observations of student externalizing behaviors; and (d) perceptions on administrative support and family involvement. Participants included 2,140 general and special education teachers randomly recruited from 45 schools. Results indicated that fewer than half of the teachers surveyed had prior instruction in CBM, reported using a wide variety of CBM practices in response to student behavior problems, and perceived higher levels of administrative support than family involvement. Implications of the study’s findings and suggestions for further research were discussed
How public service media are changing in the platform era: A comparative study across four European countries
Authors: Dragomir Marius , Túñez López Miguel
Published: October 2024

Despite enjoying a series of advantages and privileges, including access to public funding and technical infrastructure, as well as a special regulatory framework allowing them to reach almost the entire population, public service media (PSM) have historically faced a number of challenges. These include opposition from privately held media and various political parties, mounting criticism from audiences, and incessant pressures from state authorities. Some have been more successful than others in defending themselves against these attacks. Some PSM institutions have gained a high level of trust as a result of their ability to maintain a balanced approach to political coverage. Some are recognised for the quality of their news content. However, some other organisations have lost credibility and audience share as a result of various pressures. The platformisation trend has had a particularly disruptive impact on public service media (PSM) organisations. The challenge of adapting to the new digital landscape has been significant, requiring careful navigation to maintain the core values that guide their operations, as defined by the European Broadcasting Union (EBU): universality, independence, excellence, diversity, accountability and innovation. This article employs a recently developed framework for examining PSM and draws upon field research to analyse the transformation of PSM in response to platformisation-related pressures in four European countries: Austria, Romania, Spain and the United Kingdom.
An estimation method for vision-based autonomous landing system for fixed wing aircraft
Authors: Ryu Hyunjee , Lim Junyoung , Lee Hongju , Moon Gunhee , Kim Kyunam
Published: October 2024

In this paper, we propose a vision-based estimation method for autonomous landing of fixed-wing aircraft for Advanced Air Mobility. The concept of autonomous flight with minimal human intervention has gained significant interest with a particular focus on autonomous landing. The goal is to overcome the limitations of existing instrument landing systems and reduce reliance on GNSS during aircraft landing. The proposed system leverages the following techniques for high-performance and real-time operations in various real-world environments and during all stages of landing. A deep learning segmentation model was directly learned, created, and used for robust runway recognition performance against environmental changes around the runway. Algorithms were designed to adapt to different flight stages considering the varying information offered by image data when the aircraft is in mid-air and on the ground. The relative lateral position from the aircraft to the runway was estimated using bird’s-eye-view conversion and inverse projection techniques instead of conventional perspective-n-point methods for reducing the recognition error occurring from the conversion between 2D image and 3D world. Finally, the mixed-precision technique was used for the segmentation model to improve inference speed and ensure real-time operation in real-world deployment. Estimation stability and reliability were improved by using a Kalman Filter to cope with sensor uncertainties caused by the real-world flight environment. Consequently, we show that the average error in the lateral position estimation by the proposed method is comparable to the accuracy of a single GNSS and demonstrate successful autonomous landing of our test aircraft with a set of flight tests.
Development and Validation of Asphalt Pavement Rutting Prediction Model with Transient Temperature Field Considered
Authors: Liu Fei , Zhou Changjun , Wang Baomin , Chen Zengtao , Fan Chengcheng , Cao Guozhen
Published: October 2024

This study developed a transient rutting analysis program based on the principles of heat transfer and the viscoelastic–viscoplastic theory of asphalt mixtures. Using the finite element model (FEM) model corresponding to the multi-layer pavement structure and the subprogram interface of ABAQUS software, along with Python programming, the program was designed to estimate rutting under transient temperature field conditions with climate conditions, traffic flow, and structure layer constitutive parameters of pavement considered. Subsequently, the program was used to validate the efficiency of the solution and analyze the influencing factors of internal temperature field and rutting depth within the asphalt pavement structure. Results showed that, based on meteorological data and recommended values of material thermal properties, the FEM of transient temperature field can accurately simulate the temperature field distribution of pavement structure. Based on loading information and dynamic modulus test, the transient temperature variable rutting with FEM proposed in this paper can simulate and calculate the rutting of pavement structure layer with some errors for different pavement conditions from 5% to 40%. Through parametric analysis of the influence factors of temperature field and rutting, the modified transient temperature field rutting prediction program can effectively simulate rutting of pavement structure, and the minor errors were less than 20%.
Utility Cut Impact Assessment and Fee Development Using Pavement Management System
Authors: Ghosh Debaroti , Dunn Sharlan Montgomery , Petersen Lisa
Published: October 2024

The purpose of this study is to estimate any damage caused by utility cuts to pavements and develop a fee schedule to recover the costs associated with such damage using the City of Pacifica, CA, U.S.’s pavement management system (PMS). To accomplish this, the study looked at the functional deterioration of pavements resulting from utility cuts. The City of Pacifica’s PMS containing a vast dataset of pavement distress spanning 15 years, comprising thousands of data points encompassing various pavement ages and conditions, was analyzed to assess the impact of utility cuts. The findings from this study include: 1) Pavements with cuts of any size deteriorate more than pavements without cuts across all age groups with one exception for older residentials with small cuts; 2) On average, pavement condition index drops by 30% if the cut area is greater than 10% of the section area; and 3) Utility cuts inflict greater damage on newer pavements (<10 years old) compared with older ones (≥10 years old). Consequently, new pavements experience an average percent reduction of approximately 33% in their remaining service life, while older pavements suffer a reduction of about 17%. The statistical analyses indicate that utility cuts caused significant damage, and supported a tiered utility cut fee structure based on functional classification, age of pavement, and size of the cut. The resulting fee schedule is based on 2021 material and construction cost estimates; consequently, implementation including an annual adjustment for inflation is recommended. Example fee calculations are provided.

Published: October 2024

The purpose of the present study was to examine the acute effect of a single aerobic or strength training session on memory of cognitively preserved older adults. In this randomized controlled clinical trial, in the first visit the participants (52.2% men, aged 68.65 ± 2.81 years-old, BMI 26.94 ± 4.09), were randomly allocated in one of three groups: AG (aerobic exercise group), SG (strength exercise group, submitted to five exercises with 15 repetitions each), and CG (control group). Participants had a short-term memory assessment (word list memory test) followed by a single exercise session, and were retested immediately after. 24 h later, participants were submitted to a long-term memory assessment about the story that was presented in the previous day. Results showed that the SG group had a significant improvement in the word list test, when comparing pre- and post-intervention scores, suggesting that a single strength training session significantly enhances short-term memory in this population.
Figures of Migration in the Classical Sociologies of Marx, Weber, and Du Bois
Authors: Schwiertz Helge
Published: October 2024

Migration is a topic of heated debate, yet it is relatively absent from sociological theory discussions. This article analyzes the extent to which structural de-thematization or specific framing of migration shapes sociological perspectives by focusing on approaches that have been canonized as “classics.” Through a rereading of Karl Marx, Max Weber, and W. E. B. Du Bois, I address absences and show how these authors have nevertheless constructed certain figures of migration: as a passive figure of forced mobility, a threatening figure of otherness, and an active figure of social transformation. How these authors depict migration is both symptomatic of their approach but also of a contemporary sociological and sociopolitical discourse that can be critically reflected in relation to these works. By showing how migration is treated in these different intellectual projects, the article contributes to a genealogy of sociological thought and its impact on contemporary perspectives regarding migration, diversity, and inequality.

Published: October 2024

In the automated spraying workshop of ship segments, poor visibility caused by dust and fog hampers the effectiveness of the video monitoring system. The traditional method used during the automated spraying process fails to provide real-time measurement of film thickness and prediction of spraying quality, resulting in uneven film thickness and high rework rates. Robotic spraying technology also faces challenges, such as the time-consuming and labor-intensive process of building and computing a highly reliable Computational Fluid Dynamics (CFD) based spraying film-forming simulation model, which cannot be reflected in real-time during the spraying process. The digital twin characterization method, based on the agent model, offers a solution to these limitations and challenges, providing new ideas and approaches for improving and optimizing the spray film formation model. This paper presents the development of a real-time characterization system for sprayed film thickness based on digital twin technology. The spraying film thickness under different working conditions is obtained using Ansys-Fluent simulation software by varying the gun height and gun speed. The predictive model for spraying film thickness is then established using the obtained simulation data and the corresponding gun height and gun speed, employing the surrogate modeling method (BP neural network). The real-time characterization system for spraying film thickness is developed by combining C# and Unity3D. Finally, in order to ensure the accuracy of the predictive model, a spraying experimental platform is built to verify the accuracy of the predictive model.
Research on microscopic fracture mechanism of glass-ceramics grinding surface based on progressive scratch test
Authors: Tan Yanqing , Ma Lianjie , Han Wei , Liu Fulan , Xu Pengyang , Gu Lichen
Published: October 2024

Progressive scratch test was carried out on the glass-ceramics to study the continuous micro-fracture mechanism of its surface, which provided an important basis for the research on the grinding mechanism of glass-ceramics. By microimaging of scratch, the continuous material removal process of glass-ceramics from ductility to ductile brittleness to brittleness was observed in micro-view, confirming that there was a ductile brittleness between ductility and brittleness on the surface of glass-ceramics. The critical point for breaking from ductility to ductile brittleness and the critical point for breaking from ductile brittleness to brittleness were measured. The machined critical depth hc1 of the composite domain of ductility and ductile brittleness and the machined critical depth hc2 of the composite domain of ductile brittleness and brittleness for glass-ceramics were further obtained by computational analysis. This study provides valuable insights into the surface machining forming and surface microstructure generating of glass-ceramics material. The research results can also provide reference on determining the critical grinding parameters of glass-ceramics material.
Conspiracy Theories: Groups, Ideology, and Status as Three Distinct Bases for Expressions in Society
Authors: Mao Jia-Yan , van Prooijen Jan-Willem , Van Lange Paul A. M.
Published: October 2024

Conspiracy theories have been treated mostly as a homogeneous phenomenon in empirical research. However, to fully understand their causes and consequences, a multifaceted approach to conspiracy theories would be useful. Here, we propose an organizational framework with three facets (groups, ideology, and status) to conceptualize conspiracy theories. Based on a review of recent research, the current contribution highlights the psychological differences between (a) perceived conspiracies within or outside of one’s valued community; (b) ideological versus nonideological conspiracy beliefs, based on whether conspiracy beliefs are directly relevant for people’s core values; and (c) upward versus downward conspiracy beliefs, that is, whether the perceived conspiracy involves a relatively high- or low-status group. Finally, we discuss some distinct consequences of these facets in affecting societally consequential behaviors, such as collective action, protest, hostility, or polarization.

Published: October 2024

Objectives:

The objectives were to explore the protective effects of electroacupuncture (EA) on senile osteoporosis in aged rats and investigate the underlying mechanisms.

Methods:

This study included aged (24-month-old; n = 16) and young (3-month-old; n = 8) male Sprague–Dawley rats. Aged rats were further randomized 1:1 to an aged control group (Aged; n = 8) and an EA treatment group (EA; n = 8). The 3-month-old rats served as young controls (Young). EA rats received EA at ST36, SP6, GB34 and SP10 bilaterally for 30 min a day, 5 days a week, for 8 weeks.

Results:

EA significantly increased serum markers of bone formation in Aged rats. There were no significant differences in serum markers of bone resorption between EA and Aged rats. Deterioration of bone mineral density (BMD) and trabecular bone architecture was observed in the Aged group, while EA significantly increased BMD of the left femur and L5 vertebral body in aged rats. Aging-induced deterioration of trabecular bone architecture was partially reversed in EA rats. Runx2 and Osterix mRNA and protein levels were significantly increased and peroxisome proliferator-activated receptor (PPAR)γ was significantly decreased in bone marrow cells in EA compared with Aged groups. The mRNA and protein levels of core constituents of the Wnt/β-catenin signaling pathway (Wnt3a, low-density lipoprotein receptor-related protein (LRP)5 and β-catenin) were significantly increased and Dickkopf 1 was significantly decreased in bone marrow cells in EA compared with Aged groups.

Conclusion:

EA may prevent bone loss and deterioration in aged rats by promoting osteogenesis via a mechanism that may involve activation of the Wnt/β-catenin signaling pathway. EA may represent a therapeutic option for senile osteoporosis.
The Effects of Governance-Related Regulatory Reform: Ownership Structure and Earnings Management in Vietnamese Listed Firms
Authors: Doan Phuong Nguyen Trang
Published: October 2024

The purpose of this study is to examine how the influence of the internal corporate governance mechanism, namely ownership structure, on firms’ earnings management (EM) practices and insider choices between accrual-based and real EM changed after regulatory reform in Vietnam. The author considers the role of three ownership types, managerial, state and foreign, and assess how the relation between ownership structure and EM was affected by the Code of Corporate Governance reform. The study relies on a comprehensive sample of 4,408 firm-year observations of 596 firms listed on either the HOSE or HNX between 2008 and 2016. The study finds a significant effect of the reform on the relation between ownership structure and EM. Thus, the reform mitigated agency problems of managers and foreign investors in Vietnamese listed firms. The study contributes to the literature as it provides a more complete picture of the effects of managerial, state and foreign ownership on EM where the protection of minority investors is generally weak and legal enforcement is low in a developing economy.
Depression Goes Social Media
Authors: Jerrentrup Maja
Published: October 2024

Looking at the hashtag #depression on Instagram, this article examines how the topic is presented and which effects this may have. As a sample shows, the hashtag is often used by people from the field of counselling/therapy, but also by micro-influencers. Posts offer information, advice and self-disclosure, aiming at affected individuals and their social surroundings. It can be assumed that the phenomenon has positive effects both for people posting through the chance of communication and networking and for affected recipients, especially as most other posts on Instagram present people very positively and provoke social comparison. Of course, the hashtag can also be misused for attention-seeking, and misinformation is also conceivable. Despite the potential of art for mental well-being, artistic works are hardly used, which may be due to the difficulty of creating such posts—but could represent interesting options in the future, especially through image generation using artificial intelligence.
Are some sports riskier than others? An investigation into child athlete experiences of interpersonal violence in relation to sport type and gender
Authors: Vertommen Tine , Sølvberg Nina , Lang Melanie , Kampen Jarl K
Published: October 2024

Interpersonal violence in sport has serious consequences for athletes, sports organisations and society at large. Despite recent advances in safeguarding sport participants from interpersonal violence, empirical evidence regarding its prevalence and risk factors across different sports remains scarce. In this study, we investigated differences in the prevalence of interpersonal violence among a convenience sample of 9989 adults from six European countries who participated in organised sport before age 18. Utilising binary logistic regression analyses and CHAID regression tree analyses, we examined variations in reported experiences of neglect, psychological, physical, non-contact sexual and contact sexual forms of interpersonal violence based on gender and three sport classifications: type of sport (individual vs. team), sports attire (non-revealing vs. body-fitting/revealing) and weight-sensitivity (less weight-sensitive vs. weight-sensitive sports). Men participating in team sports reported significantly higher levels of victimisation across all types of interpersonal violence. Women in sports with non-revealing attire and men in less weight-sensitive sports also reported higher prevalence rates. The study underscores the need for a nuanced understanding of interpersonal violence characteristics and dynamics across different sports. Insights into the factors influencing victimisation enable tailored prevention and response strategies to be developed to better address the needs of athletes and sport organisations.

Racial Governance in Postwar Chicago: A Multiple Orders Perspective
Authors: Rast Joel
Published: October 2024

Much theorizing about patterns of urban governance portrays urban governing arrangements as unified political orders of some kind, be they progressive, neoliberal, or defined by power structures such as urban regimes or growth machines. In this study of racial governance in postwar Chicago, I borrow from literature on American political development to advance a multiple orders perspective in which racial governance is conceptualized as combinations of overlapping elements, at times in conflict with one another. Examining three distinct periods during the postwar era, I show how intersections among multiple political orders resulted in change at certain times and stability, or the appearance of stability, in others. Against arguments that portray urban political development as long periods of equilibrium punctuated at times by brief episodes of change, I find seemingly stable arrangements to be more precarious than they appear, as multiple orders impinge on one another and create frictions that can be key sources of change.
Wilderness Medicine Curricula in US Multidisciplinary Training Courses
Authors: Holstrom-Mercader Maria , Flamm Avram
Published: October 2024

Introduction

Wilderness medicine (WM) is the study of medicine in austere environments. There are several US multidisciplinary courses that teach WM to people from varying medical backgrounds. However, WM topics are covered to different extents. This study's purpose was to compare WM components among US multidisciplinary training courses.

Methods

The American College of Emergency Physicians WM fellowship curriculum's 19 components and the Fellowship of the Academy of Wilderness Medicine's 12 core and 16 elective competencies and their credits were used as two control lists. Curricula from 10 US multidisciplinary courses were analyzed for WM components. Using descriptive analysis, each course curriculum was compared with the controls.

Results

This study examines WM components in 10 courses. The greatest number of American College of Emergency Physicians WM fellowship topics (14 of 19) was covered by the Paramedic course and the fewest number (4 of 19) by the Tactical Combat Casualty Care–Combat Lifesaver course. The greatest number of Fellowship of the Academy of Wilderness Medicine core credits (56) was offered by the Paramedic course and the fewest number (24) by the Tactical Combat Casualty Care–Medical Personnel course. The greatest number of Fellowship of the Academy of Wilderness Medicine elective credits (83) was offered by the Paramedic course and the fewest number (25) by the Tactical Combat Casualty Care–Combat Lifesaver course.

Conclusion

This research analyzed WM components in US multidisciplinary courses and demonstrated that each covers WM topics to varying extents. This shows an opportunity for these courses to expand their WM education within their scope. It also demonstrates competencies offered by different courses for interested trainees.
Improving Behavior in a Self-Contained Elementary Classroom for Students With Emotional or Behavioral Disorders: A Study of CW-FIT

Class-wide Function-related Intervention Teams (CW-FIT) is a classroom management intervention in which teachers incorporate positive behavior support (PBS) principles by teaching specific classroom expectations and providing feedback on student behavior as part of an interdependent group contingency. Interventions like CW-FIT may be helpful for students with emotional or behavioral disorders (EBD), as such students often struggle to succeed in school. In the present replication study, researchers examined the effects of CW-FIT in a self-contained elementary EBD classroom. One teacher and her five students with EBD participated. Researchers used an A-B-A-B withdrawal design with maintenance probes to examine changes in students’ on-task behavior, as well as teacher praise and reprimand rates. Results revealed the teacher was able to implement CW-FIT with fidelity with corresponding increases in student on-task behavior and teacher praise, though there was little effect on teacher reprimands. The teacher and the students found CW-FIT to be socially valid. Results suggest CW-FIT can be an effective classroom management intervention in self-contained elementary EBD classrooms.

Internalizing problems are common mental health concerns among children and youth. Identifying malleable risk factors that are associated with internalizing problems, such as not having a trusted adult at school, can lead to positive behavior supports to reduce student risk. The purpose of this study was to evaluate the association between student-reported internalizing problems and having an adult to talk to at school. Students in elementary, middle, and high school ( N = 13,881) in the Midwestern United States provided self-report data about their internalizing symptoms and whether they had an adult to talk to at school if they had a problem. Participants were 51% male and 72% White; 40% qualified for free or reduced lunch and 12% were in special education. A series of growth models revealed that not having a trusted adult at school was a strong risk factor for internalizing symptoms over the school year. Moreover, lack of a trusted adult was associated with worsening internalizing symptoms over time for middle and high school students. The findings have implications for identifying students and planning supports to alleviate this risk.
Uncovering the role of English language teaching coursebooks in safeguarding intangible cultural heritage / Explorando el rol de los libros de texto de inglés para salvaguardar el patrimonio cultural inmaterial

Published: October 2024

UNESCO and local organizations raise concern over the threats towards Intangible Cultural Heritage (ICH) and continue their efforts to get help from any field possible for introducing ICH elements and raising awareness. Education is one of those fields. Considering the relation between culture and English language teaching, ICH can be incorporated into English classrooms. Besides, being the primary source of input in a language classroom, ELT coursebooks can serve as a bearer of culture. In this regard, this paper discusses the role of English language teaching coursebooks in the safeguarding of ICH by revealing the representation of ICH elements in locally produced coursebooks from 16 different countries: Bulgaria, Chile, China, Colombia, Croatia, Germany, India, Indonesia, Japan, Malaysia, Norway, Republic of Korea, Romania, Türkiye, Ukraine and Uzbekistan. Findings from the study supported the idea that ELT coursebooks can be utilized as a medium for safeguarding ICH while improving the learners’ language skills.
From the margins to the mainstream: Entrepreneurial theorization and the spread of a new collective identity within a mature organizational field
Authors: Ierfino-Blachford Laura , David Robert J
Published: October 2024

We study the effects of entrepreneurial theorization on the spread of a new collective identity within a mature organizational field. Mature fields are characterized by dominant logics, entrenched practices, and stable patterns of interaction, resulting in isomorphism and inertia. Yet, mature fields do change, often as a result of entrepreneurial activity. Whereas prior work has focused on the creation of “oppositional” niches within mature fields, we focus on an identity movement that transformed the core of a field. We do this within the context of the Canadian wine field, a field that remained stable from the end of Prohibition through the 1970s. For decades, large incumbents projected a European identity for their wines and gave these wines “faux” European names. In contrast, pioneering entrepreneurs projected a distinctly Canadian identity for their wines, an identity that was ultimately adopted by incumbents. In this way, domestic wine in Canada became tied to place rather than divorced from it. We show how entrepreneurial theorization of the “Canadian wine” identity by small producers and identity pioneers spread to the center of the field, and how the effects of theorization depended on the authenticity of these theorizers. We also suggest that an identity movement that engages incumbents rather than seeks to create an oppositional category is more likely to reach the center of a mature field.
Preclinical Testing Strategies for Epilepsy Therapy Development

Published: October 2024

The development of antiepileptogenic and disease-modifying treatments for epilepsy is a key goal of epilepsy research. Technological and scientific advances over the past two decades have seen the development of numerous therapeutic approaches, many of which show great promise in animal models. To facilitate and de-risk the translation of these promising approaches, however, rigorous preclinical testing is needed. For the present review, we discuss challenges and approaches to conduct preclinical testing of antiepileptogenic and disease-modifying treatments in animal models.
A New Technique for Creation of Femoral Vein Monocusp Neovalve for Patients With Primary Deep Vein Incompetence
Authors: Sekar Natarajan , Rajan Archana , Sima Rahul
Published: October 2024

Chronic venous insufficiency due to deep vein incompetence (DVI) is difficult to treat and is prone for failure and recurrence of venous ulcers. A variety of techniques have been tried to create valve competency but majority of them have been difficult to perform and have not shown long term results. Opie reported a technique for construction of a monocusp neo valve. We have modified this procedure and successfully corrected the deep vein reflux in a patient with primary DVI.

Methods

Monocusp valve was created by folding the vein wall flap so that both sides of the valve will have intimal surface.

Result

Patient had excellent symptomatic improvement. The venous ulcer healed with skin grafting and had not recurred at 30 months follow up. Descending venogram and duplex scan showed mild reflux.

Conclusion

Monocusp neo valve creation for primary DVI is a simple procedure with good long-term result.
