The New Discipline Machinery: Examining the Use of Apps for Classroom Behavior Management
Authors: Cho Vincent , Irby Decoteau J. , Borowiec Katrina
Published: March 2024

Background/Context:

In thousands of classrooms throughout the United States and internationally, behavior management apps have become an integral part of schools’ discipline machineries. Such apps are designed to help teachers enforce rules, especially when it comes to rewards and punishments within school token economies. To understand how these apps are beginning to shape and reshape schooling, research is needed that sheds light on the values and beliefs underpinning their use.

Purpose:

The purpose of this study is to describe and analyze three schools’ discipline practices involving behavior management apps. Our two research questions focused on the paradigms underpinning schools' discipline models and on the influence of these paradigms on schools’ app uses. Our investigation is informed by the scholarship on classroom management, as well as key concepts from Foucault’s (1977) Discipline and Punish.

Research Design:

This qualitative, comparative case study drew on data gathered at three urban schools. In total, 34 interviews were conducted with campus administrators and teachers. Within-case portraits described paradigms and practices at each school, and cross-case analyses addressed patterns across the schools.

Findings:

Schools’ behavior app uses were underpinned by differing school discipline paradigms. Although all three schools saw behavior apps as fostering orderly classroom environments, schools’ practices were underpinned by differing sets of values and beliefs (e.g., accountability/social control; neoliberalism; positivity and fun). In this way, the look and feel of app practices, and, ultimately, schools’ overarching discipline systems, also varied.

Conclusions:

This study examines a widespread, yet understudied, educational technology. By problematizing the values and beliefs underpinning teachers’ behavior app practices, the present study invites scholars and practitioners to question how rewards, punishments, and relationships manifest in schools. In doing so, it highlights opportunities to join with students, parents, and other stakeholders in broader conversations about schooling and discipline.
Do Great Minds Think Alike? High-Ability Male and Female Students’ Perceptions of Mathematics
Authors: Calabrese Julia E. , Sanders Miriam M. , Edmunds McKennah , Capraro Robert M.
Published: March 2024

Many researchers have debated potential differences between male and female students’ mathematical performance. One important factor that can impact performance is perception of the content. The purpose of the study is to investigate factors that impact high-ability male and female students’ perspectives of mathematics. Participants ( n = 12; n f = 5, n m = 7) attended a 10-day residential summer camp during which the researchers conducted individual, semistructured interviews with each participant. Using a thematic analysis, the researchers examined the interview transcripts for themes by gender. Six common themes emerged between male and female students: perseverance, performance, self-efficacy, enjoyment of content, social component, and life relevance. Female students reported that adult influence was also a factor. Further examination showed that female students are more likely to report enjoyment of content as a factor, whereas males are more likely to report perseverance and performance.

Published: March 2024

Lung pleomorphic carcinoma is a rare and aggressive cancer that uncommonly metastasizes to the colon and only a few case reports have been published thus far. We present an exceptional case of colon metastasis from lung pleomorphic carcinoma in a 68-year-old man which was revealed by large bowel perforation, and we review the previous three published cases. Metastasis to the bowel from primary lung malignancy often lacks specific symptoms which result in delayed diagnosis. Bowel metastasis is a poor prognostic factor in patients with lung pleomorphic carcinoma, regardless of management strategy.
Push and Pull: Role of Therapist Mentalizing in Navigating Therapeutic Distance
Authors: Sikand Mehak , Bhola Poornima
Published: March 2024

In the relational playground of psychotherapy, negotiating therapeutic distance is crucial for the process as well as the outcome of treatment. The challenge of navigating this closeness and distance may be accentuated during emotionally charged interactions in therapy. Therapist and client may get locked in complementary, rigid positions, leading to either submission or resistance to the others’ demands. The therapist’s ability to respond appropriately to these pushes and pulls is supported by their ability to mentalize, which is their ability to attend to and understand their own states of mind while being aware of others’ states of mind. Therapists are expected to maintain a mentalizing stance throughout and despite the relevance and impact of therapist mentalization, there is relatively less research, training, or practice-related guidance on how to maintain this balance. We use case illustrations to demonstrate therapeutic interactions that can trigger non-mentalizing for the therapist and reflect on ways of recognizing and addressing these patterns related to closeness and distance. We also share recommendations for reflective practice and supervision, training as well as research on therapist mentalization.

Published: March 2024

Methamphetamine (Meth) is a highly addictive stimulant. Its potential neurotoxic effects are mediated through various mechanisms, including oxidative stress and the initiation of the apoptotic process. Thymoquinone (TQ), obtained from Nigella sativa seed oil, has extensive antioxidant and anti-apoptotic properties. This study aimed to investigate the potential protective effects of TQ against Meth-induced toxicity by using an in vitro model based on nerve growth factor-differentiated PC12 cells. Cell differentiation was assessed by detecting the presence of a neuronal marker with flow cytometry. The effects of Meth exposure were evaluated in the in vitro neuronal cell-based model via the determination of cell viability (in an MTT assay) and apoptosis (by annexin/propidium iodide staining). The generation of reactive oxygen species (ROS), as well as the levels of glutathione (GSH) and dopamine, were also determined. The model was used to determine the protective effects of 0.5, 1 and 2 μM TQ against Meth-induced toxicity (at 1 mM). The results showed that TQ reduced Meth-induced neurotoxicity, possibly through the inhibition of ROS generation and apoptosis, and by helping to maintain GSH and dopamine levels. Thus, the impact of TQ treatment on Meth-induced neurotoxicity could warrant further investigation.

Endarterectomy may be an effective additional treatment for three diffuse coronary artery disease complicated with diabetes
Authors: Li Haiming , Gu Chengxiong , Li Bo
Published: March 2024

Objective

In order to evaluate the clinical efficacy of coronary endarterectomy (CE) and coronary artery bypass grafting (CABG) in patients with diabetes complicated with three diffuse coronary artery stenosis.

Methods

A retrospective analysis was conducted on 460 patients with diabetes mellitus and diffuse three-vessel coronary artery disease who underwent CABG in our department from September 2015 to December 2021. The patients were divided into two groups according to whether they underwent CE: the simple CABG group (group A, n = 254) and the CABG combined CE group (group B, n = 206). The perioperative outcomes, recurrent angina pectoris during 1-year follow-up, and the patency rate of the grafted vessel in coronary CT angiography were compared between the two groups.

Results

There was no significant difference in the 30 days mortality rate between the two groups (2.3% vs 2.4%, p < 0.05). Group A had a shorter operation time [(3.55 ± 0.59) h versus (4.35 ± 0.65) h], less bypass grafts [(2.72 ± 0.83) versus (3.65 ± 0.72) vessels/case], a lower incidence of perioperative myocardial infarction (7.1% vs 12.6%), and a lower number of patent graft vessels at 1-year follow-up [(2.15 ± 0.42) versus (2.88 ± 0.68) vessels/case] compared with group B (all p < 0.05). Group A had a higher incidence of recurrent angina during follow-up (14.49% vs 6.47%) ( p < 0.05). Although there was no significant difference in the incidence of MACCE events between the two groups, the probability of revascularization was higher in group A.

Conclusion

Compared with single CABG, combined CE in patients with diabetes mellitus and diffuse three-vessel coronary artery disease can achieve more complete revascularization, reduce the recurrence of angina pectoris and the needing of postoperative revascularization, but the incidence of perioperative myocardial infarction is higher.
Reliability and validity of the medial standing overhead arm reach (SOAR) test as a measure of functional hip adduction motion
Authors: Grimes Jason , Wager Justin , DiZinno Casey , Fogarty Thomas , Hund Eric , Rooney Brendan , Roy Taylor , Goldfarb Jon , Bauer Paul
Published: March 2024

Objective

The Posterior Standing Overhead Arm Reach (SOAR) test has been previously reported as a reliable clinical measure of closed chain hip extension motion. The proposed Medial SOAR test expands on that testing approach to provide a similar measure of functional hip adduction motion. This was a preliminary intrarater and interrater reliability and validity study of the Medial SOAR test as a measure of functional hip adduction.

Design

Cross-sectional.

Setting

University motion analysis laboratory.

Participants

Fifty hips were assessed in 25 (22 female) asymptomatic participants (mean age = 23.4 years, SD = 0.8).

Main measures

Maximum hip adduction during the Medial SOAR test was measured with a standard goniometer independently by two examiners. The test was also performed using three-dimensional motion capture. The intrarater and interrater reliability of the goniometric measure was determined using intraclass correlation coefficients, and the relationship between measures obtained via goniometry and three-dimensional motion capture was assessed with Pearson correlations and Bland–Altman analysis.

Results

Intrarater reliability (ICC2,3) was 0.88 (95% CI = 0.80–0.92) for Examiner 1 and 0.87 (95% CI = 0.79–0.92) for Examiner 2. The standard error of measurement and minimal detectable change were less than 3.0°. Interrater reliability demonstrated an intraclass correlation coefficient = 0.62 (95% CI = 0.28–0.79). Pearson correlations were significant with low-to-moderate associations (r = 0.49, P < 0.001; r = 0.24, P = 0.045).

Conclusions

Similar to the previously reported Posterior SOAR test, the Medial SOAR test demonstrated acceptable intrarater and interrater reliability, along with low-to-moderate associations with three-dimensional motion capture. The Medial SOAR test has the potential to provide a reliable and accurate assessment of closed chain hip adduction.
The characteristics of music video experiences and their relationship to future listening outcomes
Authors: Dasovich-Wilson Johanna N , Thompson Marc , Saarikallio Suvi
Published: March 2024

Music videos are a popular method of consuming music; however, the characteristics of these experiences and their effects on music perception are poorly understood. An online survey ( N = 155) was designed using theoretical insight from Dasovich-Wilson et al.’s (2022) Intention Attention Reaction and Retention (IARR) framework. The survey consisted of two parts: the first explored the key characteristics of music video experiences, and the second explored their effects on subsequent listening outcomes. Separate principal component analyses (PCAs) were performed on each part to differentiate between the experience itself (Experience components) and the effects on subsequent listens (Retention outcomes). Relationships between Experience components and Retention outcomes were explored using correlation and regression analyses. The results suggest that music video experiences characterized by performance gestures and narratives have the strongest influence on music perception. These findings shed light on how extramusical information from music videos influences mechanisms related to visual imagery and personal associations.

Published: March 2024

Artificial intelligence (AI) is rapidly evolving and has transformative potential for interventional radiology (IR) clinical practice. However, formal training in AI may be limited for many clinicians and therefore presents a challenge for initial implementation and trust in AI. An understanding of the foundational concepts in AI may help familiarize the interventional radiologist with the field of AI, thus facilitating understanding and participation in the development and deployment of AI. A pragmatic classification system of AI based on the complexity of the model may guide clinicians in the assessment of AI. Finally, the current state of AI in IR and the patterns of implementation are explored (pre-procedural, intra-procedural, and post-procedural).
Navigating Academic Identity: Autoethnography of Otherness and Embarrassment Among First-Generation College Students
Authors: Ben-Lulu Elazar
Published: March 2024

As a first-generation college student (FGCS), I have never felt entirely comfortable with this label, both in academic spaces and in various personal family situations. The notion of being a FGCS has evoked internal embarrassment, a sense of academic otherness, and external micro-aggressions. Through an autoethnographic analysis of my participation in the FGCS annual workshop, I explore the strengths and weaknesses of this category. The workshop provided insights into the diverse experiences of FGCSs, revealing it to be a fluid academic construct with multiple voices and narratives. However, when intersecting with other identities, the fragility of the FGCS category emerged, leading to conflicting conversations and resistance among participants. A rigid definition of FGCS overlooks its historical context of social exclusions and disregards the unique sensitivities and differences among ethnic and national groups within it. This approach weakens the struggle of marginalized groups and perpetuates their exclusion, both on and off campus. Acknowledging the complexity and diversity within the FGCS category can foster a more inclusive environment that respects the unique experiences of each individual. This approach paves the way for a comprehensive understanding of the challenges faced by FGCSs and empowers them to navigate their academic journeys with confidence.
‘A Good Death’: One Hospice Chaplain’s Approach to End-of-Life Care
Authors: Pettigrew Rachael N , Cawdor Madison
Published: March 2024

When doctors determine patients’ life expectancy to be six months or less, patients are considered palliative. Hospice offers care for the terminally ill patient’s body, mind and spirit. As part of the hospice team, chaplains support the spiritual needs of the patient and their family – a challenging and rewarding role. Dr Madison Cawdor shares his extensive experience as a United States-based hospice chaplain and explains the role’s demands, including the importance of both being present with and listening to patients while also employing an interdenominational approach (i.e. supporting regardless of religious practice). Dr Cawdor explores the role’s personal impacts, including being on call, sustained exposure to death and grief, and also the satisfaction of supporting patients. The demand for hospice care is projected to increase dramatically in the coming years, making understanding the demands of and approaches to this work crucial to facilitate both the recruitment and the retention of hospice chaplains.
Preparation and characterisation of heat‐resistant fluorinated co‐polyimides and their gas transport characteristics

Published: March 2024

A series of fluorinated co-polyimide films based on the 6FDA-FTPPA/BAFL backbone were prepared from 4-(3-fluoro-4-(trifluoromethyl)phenyl)-2,6-bis(4-aminophenyl)pyridine (FTPPA),commercial 9,9-bis(4-aminophenyl)fluorene (BAFL), and 4,4’-(hexafluoroisopropylidene)diphthalic anhydride (6FDA), with varying ratios of FTPPA:BAFL units (3:1, 2:1, 1:1, 1:2, and 1:3). Co-polyimides not only exhibit high thermal stability ( Tg > 357°C), good optical properties (λcutoff > 327 nm) and hydrophobicity (contact angle >91.4°), but also favorable solubility properties in both high and low boiling organic solvents. The fractional free volume of the polymers was simulated using molecular mechanics and molecular dynamics and correlated with experimental gas separation data. The presence of bulky groups led to high FFVs (>17.8%) and the formation of large microcavities with diameters ranging from 5.48 to 5.72 Å, which efficiently increased gas permeability. In pure gas permeation experiments, the permeability coefficients of CO2 and He for the 6FDA-FTPPA/BAFL (3:1) film were 41.48 and 79.38 bar, respectively, which were superior to those of commercial Matrimid and Kapton in terms of gas permeability. In especial, the 6FDA-FTPPA/BAFL (1:2) and 6FDA-FTPPA/BAFL (1:3) in co-polyimide membranes exhibited the most attractive separation performance for O2/N2 gas pairs, approaching the 1991 Roberson upper limit.
Reporting assassinations in the Ethiopian press
Authors: Weldemikael Berhanu Asfaw
Published: March 2024

This paper aims at analyzing the reporting of assassinations in the Ethiopian press from a discourse analytical perspective. The study attempted to answer three questions: 1) How are assassinations represented in the press? 2) What identities are set up for those involved in the assassinations? And, finally, how is meaning communicated in various discursive structures and communicative events? To that end, the study employed Jeffrie’s critical stylistics as an analytical framework within a qualitative design. The data were collected from five Ethiopian newspapers that were selected purposively in line with predetermined criteria. A corpus of 102 media stories that were published from June 2018 to June 2020 was setup. The findings show that each outlet reported the incidents synonymously, emphasizing a scapegoating process that could ideologically reaffirm the dominant political discourse. In doing so, four naming and labeling strategies were identified: lionizing (making the dead a hero), blaming and demonizing, victimizing (making the dead innocent and martyrs), and ethnification (connecting both the victims and offenders to their ethnic belongings). Polarized representations of actions, space, time, and society were evident in the selected stories. The government, together with its different organs and affiliates, was used as the sole and primary source of information. The voices of the government on the incidents were reported as widely accepted facts, as evidenced by the blurred line between direct and indirect speeches. This in turn helped to reaffirm the existing dominant political discourse – the status quo.

Published: March 2024

Background

In 2017, belimumab (BEL) was approved in subcutaneous (SQ) administration. The effectiveness after switching from intravenous (IV) to SQ and patient satisfaction in daily clinical practice has not been studied. During the pandemic, patient follow-up and treatment were significantly affected, and some patients need a change from IV to SQ. Our aim was to evaluate daily clinical practice satisfaction to SQ BEL therapy in patients previously treated IV BEL. We hypothesized that SQ BEL in SLE patients previously treated with IV BEL was similar in effectiveness and conferred higher satisfaction.

Methods

Observational, multicenter study, conducted in 7 reference centers in Catalonia. We included stable SLE patients (EULAR/ACR 2019) on treatment with SQ BEL and previous use of IV BEL (at least 3 months on IV BEL before switching). Since there are no well-validated tools for SQ BEL treatment satisfaction, we used RASQ-SQ, validated in patients with lymphoma who switched from IV Rituximab to SQ treatment, and modified for BEL treatment.

Results

Twenty-seven patients were included. The more prevalent clinical manifestations observed were related to the skin and joints and the patients had a mean baseline SLEDAI of 2.96 (SD 2.4) and SLICC score of 0.67 (SD 0.88). The median time from treatment with IV BEL before switching to SQ was 21 months (range). 84% of patients reported confidence in SQ BEL. 85.2% felt that treatment with SQ BEL was convenient or very convenient. 85% felt they had gained time with the change. 89% would recommend the SQ injection to other patients. Disease activity (mean SLEDAI) and remission rates remain stable after switching. No major new adverse effects were reported.

Conclusions

Overall satisfaction, satisfaction with via of administration, and satisfaction with the time taken to receive BEL were higher for SQ BEL treatment. A switching SQ strategy is a reasonable alternative for BEL patients.
Comparison of the SLE Risk Probability Index (SLERPI) scale against the European League Against Rheumatism/American College of Rheumatology (ACR/EULAR) and Systemic Lupus International Collaborating Clinics (SLICC) criteria

Introduction

Timely diagnosis and proper recognition of Systemic Lupus Erythematosus (SLE) is essential to establish early management in inpatients and outpatients. There are different classification scales to identify SLE, which include various clinical and serological aspects. In 2021, the SLE Risk Probability Index (SLERPI) was published, which focuses predominantly on the clinical characteristics of patients with suspected SLE and uses a simple algorithm for early recognition of the disease. The aim of this study is to compare the European League Against Rheumatism/American College of Rheumatology (ACR/EULAR) classification criteria, the Systemic Lupus International Collaborating Clinics (SLICC) criteria, and the SLERPI criteria in a cohort of Colombian patients with SLE and to analyze the correlations observed between their absolute scores.

Methods

A registry of SLE patients from two referral hospitals in Bogotá, Colombia, was used. 2021 SLERPI, 2019 ACR/EULAR, and 2012 SLICC scores were calculated for each patient and the correlations found between the scales were analyzed. The sensitivities of each were compared, and frequency analyses were conducted among different clinical and laboratory variables.

Results

Between 2016 and 2019, 146 patients diagnosed with SLE were registered, including inpatients and outpatients. The median age was 36 years (interquartile range 26–51), and 82.2% were women. According to the SLERPI criteria, a high prevalence of antinuclear antibodies (92%), immunological disorders (71%), and arthritis (64%) were observed. The most used treatments were corticosteroids (87.6%) and chloroquine (67.8%). A Spearman evaluation analysis was performed, with a moderately strong correlation of 0.76 ( p = .000) between the SLERPI and ACR/EULAR scales and very strong correlation of 0.80 ( p = .000) between the SLERPI and SLICC. Patients classified with SLE according to the SLERPI scale exhibited a higher incidence of hematological compromise, along with elevated levels of serological markers such as anti-DNA antibodies. Additionally, this group more commonly received treatments involving corticosteroids and azathioprine, and displayed a higher prevalence of hypertension.

Conclusion

The SLERPI scale could be useful in the diagnosis of SLE, especially in early stages, given its good correlation with other classification scales and its good sensitivity.
Extended excess hazard models for spatially dependent survival data
Authors: Amaral André Victor Ribeiro , Rubio Francisco Javier , Quaresma Manuela , Rodríguez-Cortés Francisco J , Moraga Paula
Published: March 2024

Relative survival represents the preferred framework for the analysis of population cancer survival data. The aim is to model the survival probability associated with cancer in the absence of information about the cause of death. Recent data linkage developments have allowed for incorporating the place of residence into the population cancer databases; however, modeling this spatial information has received little attention in the relative survival setting. We propose a flexible parametric class of spatial excess hazard models (along with inference tools), named “Relative Survival Spatial General Hazard,” that allows for the inclusion of fixed and spatial effects in both time-level and hazard-level components. We illustrate the performance of the proposed model using an extensive simulation study, and provide guidelines about the interplay of sample size, censoring, and model misspecification. We present a case study using real data from colon cancer patients in England. This case study illustrates how a spatial model can be used to identify geographical areas with low cancer survival, as well as how to summarize such a model through marginal survival quantities and spatial effects.
Combining multiple biomarkers linearly to minimize the Euclidean distance of the closest point on the receiver operating characteristic surface to the perfection corner in trichotomous settings
Authors: Mosier Brian R , Bantis Leonidas E
Published: March 2024

The performance of individual biomarkers in discriminating between two groups, typically the healthy and the diseased, may be limited. Thus, there is interest in developing statistical methodologies for biomarker combinations with the aim of improving upon the individual discriminatory performance. There is extensive literature referring to biomarker combinations under the two-class setting. However, the corresponding literature under a three-class setting is limited. In our study, we provide parametric and nonparametric methods that allow investigators to optimally combine biomarkers that seek to discriminate between three classes by minimizing the Euclidean distance from the receiver operating characteristic surface to the perfection corner. Using this Euclidean distance as the objective function allows for estimation of the optimal combination coefficients along with the optimal cutoff values for the combined score. An advantage of the proposed methods is that they can accommodate biomarker data from all three groups simultaneously, as opposed to a pairwise analysis such as the one implied by the three-class Youden index. We illustrate that the derived true classification rates exhibit narrower confidence intervals than those derived from the Youden-based approach under a parametric, flexible parametric, and nonparametric kernel-based framework. We evaluate our approaches through extensive simulations and apply them to real data sets that refer to liver cancer patients.
Students’ Sustainable Entrepreneurship Intentions: The Role of Sustainable Values and Culture
Authors: Gimenez-Jimenez Daniela , Harc Martina
Published: March 2024

Sustainable values have been enforced in societies, given individuals’ awareness of the societal challenges faced by current and future generations. Building upon the theory of planned behaviour and the value literature, this article examines whether and how sustainable values, specifically pro-environmental and solidarity values, influence sustainable entrepreneurial intentions in two different cultural contexts: Ecuador and Germany. About 297 university students were recruited to test the hypotheses. The findings reveal cultural differences in how sustainable values are associated with the behavioural mechanism that leads to sustainable entrepreneurial intentions. Surprisingly, pro-environmental values are not related to the behavioural mechanism that leads to sustainable entrepreneurial intentions in either Germany or Ecuador, whereas the solidarity values—sustainable entrepreneurial intentions relationship is fully mediated by behavioural mechanisms in Ecuador, and in Germany, the attitude towards sustainable entrepreneurship and perceived behavioural control towards sustainability partially mediate this relationship. These findings demonstrate the importance of contextualising entrepreneurial intentions in the context of sustainable entrepreneurship.
Transforming HR Functions Through Shared Service: Insights from Indian Public Sector Power Major
Authors: Rai Alka , Maheshwari Sunil
Published: March 2024

The case is about a prominent Indian public sector power company involved in the entire power generation value chain, encompassing fossil, hydro, nuclear and renewable energy sources. The organization is geographically divided into eight zones/regions: Central Region, DBF Region, Western Region-I, Western Region-II, Eastern Region-I, Eastern Region-II, Northern Region and Southern Region.

In a conversation between Mr Anuj Kapoor, the Director of HR at this major power company, and Ms Abhika Choudhary, a researcher and academician, the discussion revolved around implementing human resources shared services (HRSS) within the organization. Initially undertaken to address manpower optimization challenges within HR functions, the complete transformation of HR functions through shared services gave Mr Kapoor valuable insights. Reflecting on this journey during the meeting with Ms Choudhary, he explored the entire spectrum from idea generation to implementation, including navigating resistance to change and post-implementation feedback.

While Ms Choudhary diligently recorded the discussion to gain practical insights into the technological intervention in organizational HR functions, the flow of the conversation encountered a hurdle when delving into one specific post-implementation feedback from employees. This feedback pertained to the dichotomy of face or faceless HR in the era of HRSS within the company.
Is This a Deceased Loved One That I See Before Me or Am I Only Dreaming?
Authors: Claxton-Oldfield Stephen
Published: March 2024

This article makes a case for examining dying person’s visions during wakefulness and their dreams during sleep as separate and unique phenomena. The reason being that the mode of experience, for example, being visited by a deceased loved one while awake and conscious vs having a deceased loved one appear in a dream while asleep, may have a different impact on the dying person. A better understanding of the content and impact of waking visions and sleeping dreams, respectively, may be beneficial to both dying persons and their families.
Stress Management Programs for Special Education Teachers
Authors: Eddy Colleen L. , Herman Keith C. , Reinke Wendy M.
Published: March 2024

Stress management programs have been developed to improve teacher coping and prevent burnout. While many of these programs have promise, few have included special educators in intervention studies. Intervention programs may be beneficial for teachers in special education to increase their awareness of stress and use of coping skills, which in turn can be modeled for students in their classrooms. Encouraging individual stress management can improve well-being and student outcomes, but may be insufficient without additional classroom management and contextual support. The purpose of this paper is to use the Garwood paper as a springboard to identify potential stress management programs that might be helpful for special educators. .
Radiographic Analysis of Valgus Ankle Deformity With or Without Medial Longitudinal Arch Collapse
Authors: Kim Jaeyoung , Palmar Joaquin , Demetracopoulos Constantine , Ellis Scott , Deland Jonathan
Published: March 2024

Background:

Establishing a surgical plan for ankle deformities necessitates a comprehensive understanding of the deforming forces involved, and the morphology of the ankle deformity plays an important role as well. Valgus tibiotalar tilt development has mostly been described in patients with a low medial longitudinal arch, as seen in progressive collapsing foot deformity (PCFD). However, some valgus ankles demonstrate no radiographic evidence of a collapsed medial arch. This study aims to investigate whether there are differences in the radiographic morphology of valgus ankle deformities between patients with and without a low medial longitudinal arch to explore if they have different etiologies.

Methods:

We retrospectively reviewed patients who underwent surgical treatment for asymmetric valgus ankle deformity at our institution between 2017 and 2021. Patients with a valgus tibiotalar tilt (TT) greater than 4 degrees and Meary angle greater than 30 degrees (mean: 38.9) were included in the PCFD group (n = 29). The non-PCFD group (n = 24) with TT greater than 4 degrees and Meary angle less than 4 degrees (mean: 0.3) was also established. In the weightbearing ankle anteroposterior view, the TT and medial distal tibial angle were measured. Additionally, to assess the mediolateral position of the talus, the talar center migration (TCM) and lateral talar dome–plafond distance (LTD-P) ratio in the coronal plane were measured. In weightbearing computed tomography (WBCT), the degree of axial plane talocalcaneal subluxation and the prevalence of sinus tarsi bony impingement were assessed. Intergroup comparison was conducted.

Results:

Both groups demonstrated a similar degree of TT, with a mean of 11.6 degrees in the PCFD group and 13.7 degrees in the non-PCFD group ( P = .2330). However, the PCFD group showed a significantly greater TCM and LTD-P ratio compared with those of the non-PCFD group ( P < .0001), indicating that PCFD patients have a more medially translated talus in ankle anteroposterior radiographs. WBCT showed that the PCFD group on average had 18 degrees greater axial plane talocalcaneal subluxation ( P < .0001) and 52% higher prevalence of sinus tarsi bony impingement ( P = .0002) compared with the non-PCFD group.

Conclusion:

This study suggests that valgus ankles may exhibit different radiographic morphologies depending on the status of the longitudinal arch. Valgus ankles in PCFD patients tend to have a more medially translated talus. This finding may suggest the presence of different deforming forces between the 2 groups and may indicate the need for different treatment strategies to address talar tilt.

Background and Aims

The diagnostic standard of coronary artery disease (CAD) is coronary angiography (CAG). Since CAG is an invasive procedure underscores the need for identifying non-invasive, effective, and innovative biomarkers. Our study aimed to retrospectively analyze hematological markers for predicting the severity of CAD.

Methods and Results

Case data were collected from 195 CAD patients admitted to the hospital for CAG. According to Gensini score, patients were divided into mild, moderate, and severe CAD groups. Blood indexes and predictive efficacy of the triglyceride-glucose (TyG) index were retrospectively analyzed. Among 195 CAD patients, 81 had mild CAD, 60 had moderate CAD, and 54 had severe CAD. Sex, fast blood glucose (FBG), TyG index, and high-sensitivity C-reactive protein (hs-CRP) significantly differed among the three groups. The TyG index demonstrated higher values in patients with moderate (9.07[8.62-9.44]) and severe (8.98[8.46-9.45]) CAD compared to those with mild CAD (8.75[8.49-9.14]). The AUC of the TyG index was 0.615 (95% confidence interval (CI): 0.536-0.694, P =.004), with a cut-off value of 8.997, specificity of 0.704, and sensitivity of 0.535. Logistics analysis showed the risk of moderate and severe CAD with an odds ratio (OR) value of 2.595 (95% CI: 1.199-5.619, adjusted P = .016) following regrouping by the TyG index optimal cut-off value of 8.997. The TyG index combined with FBG and hs-CRP had an elevated AUC value, significantly higher than other combinations ( P  =  .011 and 0.02, respectively).

Conclusions

The severity of CAD is positively correlated with an increased TyG index value. A combination of TyG, FBG, and hs-CRP has demonstrated improved diagnostic efficiency, suggesting its potential as a novel indicator for predicting and diagnosing CAD progression.
Multichannel multiscale increment entropy and its application in roller bearing fault diagnosis

As a new index to measure the complexity of time series, increment entropy, which takes into account the fluctuation directions and amplitude of time series, has better performance than the traditional entropy analysis methods such as sample entropy and permutation entropy. However, the increment entropy value of time series at single scale cannot completely reflect the dynamic change of time series. In this paper, the multichannel multiscale increment entropy (MMIE) is proposed by introducing the coarse-graining and multichannel analysis tools of time series to explore the complexity of multichannel time series over multiple different scales. MMIE considers the dynamic relationships between multichannel data and the relevant cross-channel variations that are often overlooked in single-channel analysis, thus achieving a full utilization of state information. Finally, an MMIE-based fault diagnosis method is proposed for roller bearing. The analysis results of the simulation signals and the measured data of roller bearings indicate that MMIE performs better than MMDE, MMPE, and MMSE approaches in time costing and fault identification rates.

Introduction

International Society of Oncology Pharmacy Practitioners guidelines recommend having standard operating procedures (SOPs) and initial and yearly retraining programs on cytotoxic spill handling for pharmacy operators (POs). This study aimed to create a simulation-based training (SBT) program on this subject and evaluate its impact on POs’ real-life performance.

Methods

Randomly formed pairs of POs underwent a 2.5-hour training program, including two simulation exercises (a broken cytotoxic vial on the floor and a leaking cytotoxic bag) in a simulated pharmacy production unit. Each participant applied the cytotoxic spill handling SOPs. The PO and trainer-pharmacist did a debriefing after each exercise. Satisfaction was recorded on a 0-to-100% scale. A 20-item questionnaire assessed general knowledge about cytotoxic spill handling before and after the training. One month before and one month after the training, the POs underwent a real-life test when the trainer broke a fake cytotoxic vial in the cytotoxic storage area. Their performance in applying the SOPs was assessed on a 20-point checklist, and the time to handle the spill was recorded.

Results

Twelve POs participated. Mean satisfaction score was 98.9%. Mean knowledge score improved from 10.8/20 (SD = 2.0) before training to 14.5/20 (SD = 1.6) after training ( p < 0.05). Mean real-life SOP performance improved from 78.6% (SD = 7.4%) to 97.1% (SD = 5.2%) ( p < 0.05). Mean time to handle cytotoxic spills decreased from 17.3 minutes (SD = 3.6 minutes) to 11.9 minutes (SD = 1.5 minutes) ( p < 0.05).

Conclusion

POs improved their knowledge and real-life competencies for handling cytotoxic spills. This training will be included in POs’ initial and continuing training programs.
Program Plan Evaluation: A Participatory Approach to Bridge Plan Evaluation and Program Evaluation

Most program evaluation efforts concentrate on assessments of program implementation and program outcomes. However, another area of programs that has not received sufficient attention in the literature is evaluating the plan of the program. Since the quality of the plan and planning process can influence program implementation and outcomes, there is a need to expand program evaluation efforts to cover program plans, and thus bridge plan evaluation and program evaluation. This paper utilizes the program evaluation literature to illustrate two approaches to participatory program plan evaluation— ex-ante or proactive and ex-post or reactive—including a conceptual framework that identifies the requirements, barriers, and strategies for evaluating program plans. Concrete examples are provided to illustrate the application of these two approaches.

Aluminium foam and Carbon Fiber Reinforced Plastic (CFRP) are widely used composite materials in automobile industries due to the benefits of lightweight and energy absorption capacity. Therefore, in this study, the numerical crashworthiness analysis of 2014 Aluminium-SiCp (2014AA-SiCp) foam filled in CFRP tube has been performed under impact loading. Quasi-static compression tests have been conducted on 2014AA-SiCp foam to extract the mechanical parameters required for numerical simulations. To understand the crushing behavior under the axial impact loading, 2014AA-SiCp foam-filled CFRP tube has been numerically modelled using ABAQUS® software. The parametric study was carried out to explore the effects of filler material, foam densities, and impact velocities on crushing behavior. It was found that load increases with the rise in foam density and impact velocity. Moreover, the deformation increases with the increase in impact velocity. Results showed that the load carrying capacity of foam filled CFRP tubes was significantly improved compared to that of empty CFRP tubes. The foam filled CFRP specimens exhibited peak load of 122 kN and an energy absorption capacity of 3012 J, showcasing an approximate improvement of 43% and 11% respectively, over the values obtained for empty CFRP tubes.

Objectives

A subtype of patients with thyroid eye disease (TED) were found to be euthyroid without prior thyroid dysfunction or treatment, known as Euthyroid Graves’ Ophthalmopathy (EGO). We report the prevalence, clinical and serological phenotypes of EGO in a Chinese population.

Methods

A cross-sectional follow-up study. Ethnic Chinese TED patients were managed at the Thyroid Eye Clinic(TEC), Prince of Wales Hospital and TEC, the Chinese University of Hong Kong between September 2007 and July 2021.

Results

A total of 66 (5%) patients among the 1266 ethnic Han Chinese TED cohort were diagnosed as EGO, and 6 (9%)of them become dysthyroid over an average of 74-month follow-up. EGO patients were associated with a longer duration between onset of the symptoms to our first consultation ( P < 0.0001), a higher male-to-female ratio ( P = 0.0045) and a higher age of disease onset ( P = 0.0092). Family history of thyroid disease was more common in TED patients ( P = 0.0216) than in EGO patients. EGO patients were more likely to present unilaterally ( P < 0.0001), and they have a larger difference in MRD1 ( P < 0.0001), and extraocular motility ( P < 0.0001) between the 2 eyes when compared to the TED patients. Notably, the extraocular motility restriction of the worst eye was more affected in EGO patients ( P = 0.0113). The percentages of patients who received IVMP, ORT and emergency or elective surgeries(decompression or squint operation) between EGO and TED were similar.

Conclusions

Understanding the important clinical phenotypes of EGO may help the clinician to make the correct diagnosis. Further study to compare EGO and TED is warranted.
