Recurrent Painful Ophthalmoplegic Neuropathy: A case report with atypical features and a review of the literature
Authors: Furia Alessandro , Liguori Rocco , Donadio Vincenzo
Published: January 2023

Introduction

Recurrent Painful Ophthalmoplegic Neuropathy, previously known as Ophthalmoplegic Migraine, is a poorly characterized disorder mainly because there are few cases described. We report a new case of Recurrent Painful Ophthalmoplegic Neuropathy and a review of the literature to contribute to increasing the knowledge of the clinical features of this disorder.

Case report and review of literature

A 45-year-old woman presented with adult-onset recurrent attacks of abducens and oculomotor palsy associated with diplopia followed by headache. Most notably, pain always presented many days after oculomotor impairment, a feature never described in the literature. A diagnosis of possible Recurrent Painful Ophthalmoplegic Neuropathy was made after excluding other possible mimicking disorders. Symptoms usually resolved gradually with corticosteroid therapy, albeit without a clear-cut benefit. Clinical data collected from 1989 to 2022 showed that adult onset in Recurrent Painful Ophthalmoplegic Neuropathy is not uncommon. While III cranial nerve palsy is typical, VI and IV nerve palsy have also been described.

Pathophysiology and diagnosis

Several hypotheses have been proposed, including nerve compression, ischemia or inflammation/demyelination, but none has been completely accepted. Diagnosis remains of exclusion; magnetic resonance imaging and blood exams are key in differential diagnosis.

Conclusions

Our case gives us the possibility to expand the clinical features of Recurrent Painful Ophthalmoplegic Neuropathy, also contributing to updating the pathophysiological hypotheses.
Relation Between Seated Person Vibrations and the International Roughness Index
Authors: Múčka Peter
Published: January 2023

Vertical vehicle feet/floor interface vibrations are typically not used to indirectly estimate road roughness. The relation for vehicle floor vibrations, the International Roughness Index (IRI), vehicle speed, and road roughness vertical displacement spectrum according to the ISO 8608: 2016 standard was previously derived only for the simulation of a reference quarter-car model. It was estimated using the in situ measurement of vibrations of a person sitting in a passenger car for different vehicle and road categories, vehicle speed, and road roughness. Vibrations at the feet/floor interface and seat surface of a seated passenger were evaluated with the frequency-weighted root-mean-square vertical acceleration according to the ISO 2631-1: 1997 standard. The results indicated that the simulated results for the quarter-car model may have substantially underestimated the ratio between the vehicle floor vibrations of a seated person and the IRI, but they were similar to seat surface vibrations.

Published: January 2023

This study analyzed motorist and bicyclist understanding and preference of positive confirmation of detection of a bicycle by the traffic signal infrastructure using a blue light detection confirmation (BLDC). The research analyzed results of an online survey of 1,123 respondents and intercept survey of 337 respondents. The study initially found that participants of the survey did not understand the meaning of the blue light itself, but comprehension of the system rose from 40% to 50% when supplemental signs were used. Respondents overwhelmingly indicated that they preferred the sign option that included symbols, text, and a representation of the blue light, in comparison with the sign options that only included symbol and text, or text and blue dot. Additionally, respondents indicated that they “strongly agree” that the supplemental signage helped with understanding the purpose of the detection confirmation devices, that they would support the system at intersections, and that it made them feel better about waiting at an intersection with light. Including supplemental signage with the symbol, text, and blue dot could potentially improve the riding experience for users, as it was strongly preferred among the alternative sign options that were tested; however, further evaluation of sign configurations may be warranted.
Linkage Problem in Location Optimization of Dedicated Bus Lanes on a Network
Authors: Bayrak Murat , Guler S. Ilgin
Published: January 2023

Methods for identifying optimal decisions for dedicated bus lane locations (DBLs) on a network have been extensively studied in the literature. However, the impacts in relation to changes to car and bus delays of deploying a DBL on a given link largely depend on where other DBLs exist on the network. Therefore, for a network-wide location optimization or a bus lane design problem, linkages exist between decision variables. Typically used metaheuristic methods to optimize DBL locations, such as genetic algorithms (GAs), do not perform well for such problems with linkages between decision variables. To this end, this paper has two novel contributions to the literature by (a) demonstrating that the linkage problem exists, and (b) testing different heuristic algorithms that are more suitable than GAs for optimizing the locations of DBL on a network. The linkage problem in the location optimization of DBLs is demonstrated by enumerating all possible bus lane locations in a small grid network. Next, optimization algorithms that do not enumerate all possible bus lane locations that are capable of learning linkages between decision variables, namely Bayesian algorithm and a population-based incremental learning algorithm, are proposed. These algorithms are compared with two types of GAs in relation to consistency and quality of the solutions, and exploration capability. Results show that algorithms that can learn linkages between decision variables perform better than the GAs.
Perception-Based Analysis of the Perspectives of Users and Non-Users of Different Shared Mobility Services
Authors: Amirnazmiafshar Ehsan , Diana Marco
Published: January 2023

Perception-based analysis is conducted in this study to specify users’ and non-users’ perceptions about shared mobility systems, including their opinions, attitudes, and actual understanding. Multi-actor multi-criteria analysis and the Bayesian best-worst method are used in this regard. From the weight analysis, the conclusion is drawn that the three most important criteria for users and non-users of shared mobility services are traveler safety, cost, and accessibility, respectively. Further, the scores of the criteria given by users are generally higher than those of non-users, except for the travel cost of scooter-sharing services, which may show that non-users underestimate it. Furthermore, the perception analysis shows that the criteria accessibility and comfort show the largest view gap between the users and non-users. Also, based on the analysis of the eight criteria examined in this study, car-sharing services are preferred by both users and non-users beyond their actual market share. In addition, cost is the only criterion that has the least contribution to the car-sharing choice by both users and non-users, which in their view, is a result of its higher service cost. Additionally, the accessibility of bike-sharing and scooter-sharing contributes more to the value of these two services for their users, while the opposite is true for non-users. Finally, non-users value the speed of scooter-sharing less than users. This study offers insights into users’ and non-users’ perceptions, especially for some qualitative choice criteria seldomly considered in econometric models.
The Flame of the West: A Perspective on the Oxford Inklings’ Vision for Imaginative Learning in Christian Scholarship
Authors: Williams Jay Lennon George
Published: January 2023

This article will address the power of imaginative learning in Christian formation in personal pedagogy as exemplified in the writings of the Oxford Inklings. Foreseeing the dehumanizing effects caused by an overemphasis on utilitarian education, their collective scholarship in literary fiction helped preserve many ideas that were the treasures of Western thought for millennia. As successful as the Oxford Inklings were in influencing their generation through literary fiction and its power to engage the imagination, using literary fiction for Christian formation remains a largely neglected mode of learning in a culture facing even greater idiological challenges—such as those presented by the Simulation Theory Hypothesis.
The Prevalence and Predictors of Compassion Satisfaction, Burnout and Secondary Traumatic Stress in Registered Nurses in an Eastern Canadian Province: A Cross-Sectional Study
Authors: Maddigan Joy , Brennan Maureen , McNaughton Kelly , White Gerry , Snow Nicole
Published: January 2023

Background

The quality of Registered Nurses’ worklife is impacting nurses’ mental health, and the standard of care received by clients. Contributing factors to nurses’ stress are the trauma of continuous caring for those in great suffering, and adverse working conditions.

Objectives

i) to explore the prevalence of work-related stress in a provincial sample of Registered Nurses; ii) to compare the levels of compassion satisfaction, burnout and secondary traumatic stress reported by nurses in hospital, community, non-direct care settings, and, iii) to identify factors that predict levels of nursing work stress.

Methods

A descriptive, predictive study with a self-report survey containing demographic questions and the Professional Quality of Life Scale was emailed to over 3,300 Registered Nurses. The scale measured the prevalence of three worklife indicators, compassion satisfaction, burnout and secondary traumatic stress. Multiple linear regression identified factors that predicted the levels of the three indicators. A subgroup analysis explored the quality of worklife based on three practice environments.

Findings

Nurses (n  =  661) reported moderate compassion satisfaction, burnout, and secondary traumatic stress. The strongest predictor, satisfaction with one's current job, predicted high compassion satisfaction and lower burnout and secondary stress. The subgroup analysis identified hospital nurses as having the most work-related stress and the lowest level of compassion satisfaction.

Conclusion

Innovative, collaborative action can transform nurses’ practice environments. Organizational support is essential to bring about needed improvements.
Patterns of Mother, Father, and Peer Attachment Quality as Moderators of Child Maltreatment Risk for Depression and PTSD Symptoms in Adolescent Females
Authors: Russotti Justin , Herd Toria , Handley Elizabeth D. , Toth Sheree L. , Noll Jennie G.
Published: January 2023

Child maltreatment (CM) is a robust risk factor for adolescent depressive and post-traumatic stress disorder (PTSD) symptoms. Quality attachment relationships have been posited as a protective factor but findings are equivocal and studies have not adequately considered the complex network of interpersonal relationships that adolescents rely on. The current study applied a person-centered approach to (a) identify subgroups of adolescent females characterized by distinct patterns of attachment quality with peers, fathers, and mothers and (b) determine if the effect of maltreatment on depressive and PTSD symptoms varied as a function of distinct patterns of attachment quality. Data came from a prospective, longitudinal cohort study of 464 racially diverse and adolescent females designed to examine the developmental sequelae of substantiated CM (260 maltreated and 204 demographically matched, nonmaltreated comparisons). Latent profile analysis (LPA) revealed four profiles of attachment characterized by: (a) above-average attachment quality across all three relationships ( N = 207, 44.6%); (b) below-average quality with father and friends and above-average quality with mothers ( N = 128, 27.6%); (c) below-average quality across all three relationships ( N = 106, 22.9%); and (d) very low-(−1 SD) quality with mothers and above-average quality with fathers and friends ( N = 23, 5.0%). Moderation models revealed that cumulative maltreatment exposure resulted in greater adolescent depressive symptoms only for those with a profile of attachment consisting of very low-quality maternal attachment and high-quality father and friend attachments. Profiles did not significantly moderate the effect of maltreatment on PTSD symptoms. Results identify subgroups of maltreatment survivors most vulnerable to the development of depression in adolescence. Such groups should be targets for the provision of finite clinical resources with clinical interventions that seek to promote healthy maternal attachment relationships to mitigate the impact of maltreatment on depression.
The Darker the Skin, the Greater the Disparity? Why a Reliance on Visible Injuries Fosters Health, Legal, and Racial Disparities in Domestic Violence Complaints Involving Strangulation
Authors: Brady Patrick Q. , Zedaker Sara B. , McKay Kelsey , Scott David
Published: January 2023

The reliance on external injuries for justice is misguided given that assault injuries may be less visible among victims of color due to increased melanin in the skin. To date, however, less is known whether racial/ethnic disparities extend to officers’ identification of signs of nonfatal strangulation (NFS). The current study estimates the extent of NFS indicators identified by officers who completed a standardized strangulation assessment in 133 family violence complaints. Breathing difficulties were the most common symptoms identified by officers (98%), followed by external signs (89%), and symptoms of impeded blood circulation (87%). Compared to cases involving White/Asian survivors, officers were less likely to identify external injuries on Black survivors’ neck, chin, and chest/shoulders. While racial/ethnic differences did not emerge for symptoms of disrupted airflow, Hispanic survivors were twice as likely to report losing control of bodily functions. Implications for policy and practice are discussed.
Prediction of stability parameters of ferric oxide nanofluids using response surface methodology based on desirability approach

Published: January 2023

Nanofluids are well known for their enhanced thermal properties. In spite of their excellent properties, there are certain hindrances to their applications on large scale. The issue of nanoparticle agglomeration in the base fluid with the consequent stability related issues is one of the main obstacles to the usage of nanofluids. Stability is crucial because the longer the nanofluids remain stable, the better their capacity to retain their thermal properties. Hence there is a need to evolve long-term stable nanofluids. Since there are a lot of factors, which are affecting the stability of the nanofluids, there is a need to optimize the process parameters. In this regard, central composite rotatable design (CCRD) was applied in this study to optimize the independent parameters of stability of ferric oxide nanofluids. For this, the performance of nanofluids was assessed by measuring the nephelometric turbidity units (NTU), based on the independent variables such as percentage of intensity of the nanoparticle, pH of the base fluid, and percentage volume concentration of the surfactant. All the parameters that are affecting individually and mutually were validated statistically using analysis of variance (ANOVA). A regression equation to evaluate the NTU was developed. The obtained results showed that the values predicted by the model and that obtained from the experiments were in good agreement with each other. It is observed that more than 99.65% of the variation could be predicted by the model developed for NTU. The response surface methodology (RSM) has revealed that the ideal process parameters for greater stability of nanofluids are 0.01% particle volume intensity, pH 3.2, and 0.6% surfactant intensity.
Novel prepared nano potassium methyl siliconate as antioxidant for nitrile rubber
Authors: Mahmoud Doaa S , Elsayed AE , Reffaee AA , El-Nashar Doaa E
Published: January 2023

In this work, novel potassium methyl siliconate (PMS) was employed as a new nano-type antioxidant for acrylonitrile-butadiene rubber (NBR). NBR/PMS composites were produced by incorporating various contents of the prepared compound as anti-ageing agents (PMS) to improve the heat resistance of these composites. Potassium methyl siliconate (PMS) was prepared, and its chemical structure was confirmed by different elemental analyses. The curing properties, filler dispersion, thermo-oxidative ageing test, mechanical properties, FTIR, and TGA of the NBR/PMS composites were evaluated. It was detected by TEM images of PMS. The particles had a rhombic shape, and the particle size ranged from 1.23 nm to 7.84 nm. PMS could successfully promote the interfacial interaction between rubber and filler and the uniform dispersion of silica particles into the NBR matrix. As a result, the mechanical characteristics of the NBR/PMS composites were significantly improved, and they were superior to those of the NBR/TMQ composites with similar filler contents. Furthermore, the crosslinking density of the NBR composites was reduced after adding PMS (an antioxidant), which had a great effect on the mechanical properties. The results exhibited that PMS dramatically enhanced the solvent extraction resistance and the thermo-oxidative ageing resistance of NBR/silica composites more efficiently than TMQ. Overall, this work extended the application scope of PMS to develop novel and effective antioxidants for elastomers.

Published: January 2023

We aimed to investigate the effects of a multi-setting lifestyle education on men’s cigarette, hookah, and passive smoking, and women’s passive smoking, in Iran. Data of Tehran Lipid and Glucose Study (TLGS) were used. TLGS started in 1999 with every-3-year follow-ups. Multi-stage cluster random sampling was used to recruit participants under the coverage of three health centers. One health center implemented multi-setting lifestyle education at school, family, and community setting. Our analytic sample for generalized estimating equation was restricted to 1322 and 3593 adults (respectively as intervention and control) who were followed for 15.8 years. Intervention reduced the odds of men’s cigarette smoking by 27%. The estimated mean cigarettes/day was 1.58 lower in intervention men. The intervention reduced the odds of men’s hookah use by 42% in short term. Intervention women had 33% lower odds of passive smoking. Lifestyle education with community outreach can help achieve pragmatic tobacco control goals.
To Be or Not to Be: The Entrepreneur in Neo-Schumpeterian Growth Theory
Authors: Henrekson Magnus , Johansson Dan , Karlsson Johan
Published: January 2023

Based on a review of 700+ peer-reviewed articles since 1990, identified using text mining methodology and supervised machine learning, we analyze how neo-Schumpeterian growth theorists relate to the entrepreneur-centered view of Schumpeter Mark I and the entrepreneurless framework of Schumpeter Mark II. The literature leans heavily toward Schumpeter Mark II; innovation returns are modeled as following an ex ante known probability distribution. By assuming that innovation outcomes are (probabilistically) deterministic, the entrepreneur becomes redundant. Abstracting from genuine uncertainty, implies that central issues regarding the economic function of the entrepreneur are overlooked such as the roles of proprietary resources, skills, and profits.
A Qualitative Inquiry of Older Afghan Refugee Women’s Individual and Sociocultural Factors of Health and Health Care Experiences in the United States
Authors: Siddiq Hafifa , Alemi Qais , Lee Eunice
Published: January 2023

Introduction:

Approximately 132,000 Afghans have resettled in the United States since the 1980s and are now aging. As older adults, sociocultural factors influence health and health-related behaviors. This study aimed to explore older Afghan refugee women’s perceptions of individual and sociocultural factors of health and health care experiences.

Methods:

A focused ethnography methodology was conducted with 27 semi-structured interviews with older Afghan refugee women, family members, and community key informants in Southern California. Recorded interviews were transcribed and analyzed using inductive thematic analysis.

Results:

Five themes were identified as key to health promotion in the post-migration setting: (a) health promotion through Islam, (b) the centrality of family, (c) ongoing stressors that impact health, (d) needing support in navigating health services, and (e) miscommunication leading to mistrust of health care providers.

Discussion:

Health interventions should consider social and cultural contexts and faith-based and family-centered approaches when addressing older Afghan refugee women’s long-term health and well-being.

Published: January 2023

Alveolar soft-part sarcoma (ASPS) is a rare soft tissue tumor that primarily involves the extremities. We report a case of a 30-year-old never-smoker man who presented with hematuria, dysuria, and constipation at an outside hospital. He was diagnosed with and treated for multiple episodes of urinary tract infection. However, he continued to have voiding symptoms for which a cystoscopy was performed and revealed a bladder neck mass. He underwent transurethral resection of a bladder tumor and was diagnosed with muscle-invasive urothelial carcinoma, nested variant, at an outside hospital. Subsequent to this diagnosis he transferred his care to our center. In-house imaging revealed a large vascular mass involving the prostate and pushing against the bladder base. Prostate needle biopsies were performed and revealed an epithelioid neoplasm with a nested growth pattern composed of cells with a moderate amount of eosinophilic cytoplasm, mildly pleomorphic nuclei, and occasional prominent nucleoli. Since the findings were not classic for urothelial carcinoma or for prostate cancer, we included a wider differential of poorly differentiated carcinoma, sarcoma, and paraganglioma. A wide panel of keratin stains was negative, ETS (erythroblast transformation-specific)-related gene highlighted an extensive vascular network and neuroendocrine stains were all negative. A transcription factor E3 fluorescent in-situ hybridization was positive and subsequently, an ASPSCR1 gene rearrangement was demonstrated. The outside hospital transurethral resection of bladder tumor was obtained for review and the tumor was morphologically similar to that seen on the in-house prostate needle biopsies. Based on the above findings a final diagnosis of primary ASPS of the prostate with involvement of the bladder was made. The patient was later diagnosed with bilateral lung metastases. He was treated with pazopanib, radiation therapy, and cystoprostatectomy and is symptom-free on a 15-month follow-up.
Periosteal Fasciitis With Unusual Radiologic Features Harboring a Novel STAG1::USP6 Fusion Gene
Authors: Mejbel Haider A. , Siegal Gene P. , Wei Shi
Published: January 2023

Periosteal fasciitis is a subtype of nodular fasciitis originating from the periosteum. The diagnosis can be challenging and requires radiologic–pathologic correlation. Advances in molecular analysis confirmed that nodular fasciitis and its related lesions harbor a USP6 gene rearrangement with one of the several potential partners. Herein, we report a case of periosteal fasciitis with metaplastic bone formation detected incidentally during a radiologic survey for breast carcinoma. Radiologic examination revealed a 2.4 cm, heterogeneous, avidly enhancing lesion of the right femoral distal metaphysis concerning for low-grade periosteal chondrosarcoma. Histological examination of a core needle biopsy revealed a tumor composed of bland spindle cells with myofibroblastic and osteoblastic phenotypes admixed with immature bone and cartilaginous elements. Molecular analysis revealed a novel STAG1::USP6 fusion that helped arrive at the right diagnosis and further expands the molecular profile of USP6-associated neoplasms.
Campus Coverage of An Execution: A Narrative Analysis
Authors: Hill Desiree
Published: January 2023

Research demonstrates that most professional journalists will experience trauma in their work. Yet almost no research has focused on college students’ coverage of a traumatic event. Narrative analysis explores the experiences of 12 university students who reported and produced execution coverage for their college newscast. The data reveal that the students struggled with feelings of detachment, uncertainty, and dread before, during, and after the coverage. The research also explored the students’ reaction to counseling sessions scheduled by faculty to mitigate the trauma. Findings illuminate a path for student media programs to follow to help students prepare for potentially troubling content.

Published: January 2023

Insulin and its secretagogues are essential for some patients with type 2 diabetes (T2D) to maintain good glycemic control (GC), but severe hypoglycemia (SH) is a concern. This network meta-analysis aimed to find optimal glucose-lowering drug treatment regimens in terms of GC and SH in T2D patients. MEDLINE and EMBASE were used to identify trials that compared two or more treatments including insulins and/or sulfonylurea or glinides and that examined both GC and SH. Treatment hierarchy was expressed as the surface under the cumulative ranking curve (SUCRA) probabilities. We identified 137 eligible trials comprising 42 treatments. The use of insulins and non-insulin glucose-lowering agents except for sulfonylurea or glinide had a higher SUCRA than insulins only for hemoglobin A1c (A1C) (p = 0.01) changes and achievement of A1C < 7.0% (p = 0.02) or A1C ≤ 6.5% (p = 0.002). The use of sulfonylurea or glinide and other non-insulin glucose-lowering agents resulted in a lower SUCRA for SH than insulins only when trials were analyzed for A1C change (p = 0.06) and achievement of A1C < 7.0% (p = 0.004) or A1C ≤ 6.5% (p = 0.004). Cluster analysis indicated that premixed insulin plus glucagon-like peptide-1 receptor agonist (Mix-ins + GLP1) belonged to the high-efficacy category for GC and glinide plus thiazolidinedione (glinide + TZD) belonged to the relatively high-efficacy category for GC among several high-safety categories regarding SH. In T2D patients, clinicians should consider appropriate combinations of non-insulin glucose-lowering agents (especially glinide + TZD) for reducing SH risk before switching to insulin therapies. If switching, they should be willing to add non-insulin glucose-lowering agents (especially, Mix-ins + GLP1) to insulins to further improve GC.
Cooperative affordances: How instant messaging apps afford learning, resistance and solidarity among food delivery workers

Published: January 2023

This paper aims to understand the practices and meanings associated with the creation and use of private chat groups on instant messaging services such as WhatsApp, Telegram, Messenger and WeChat that are accessible only to platform workers of online food delivery services. We draw on participant observation in five countries (Italy, Spain, Mexico, China, and India), in-depth interviews with 68 food delivery couriers and digital ethnography ( Pink et al., 2015 ) within dozens of online private chat groups of food delivery workers. Our fieldwork shows that private chat groups are extremely relevant in the daily work of delivery workers and are appropriated to restore forms of mutualism not afforded by the food delivery apps. Following Costa (2018) and her concept of affordances- in-practice, we describe how the practice of online private chat groups created by platform workers affords: (1) the emergence of communities of practice; (2) resistance and contempt; (3) mutualism and solidarity. We argue that these workers ‘enact’ the affordances of instant messaging apps, to supplement – from below – the affordances of food delivery apps that were denied or ignored by food delivery companies. We argue that these affordances constitute cooperative affordances. This concept captures the cooperative nature of peer-to-peer communication that occurs within the informal online chat groups created by the workers themselves. Finally, this article contributes to affordance theory by highlighting how affordances are not immanent properties of artifacts, or ‘invariants’, as argued by Gibson (1979) , but can be ‘enacted’ by specific users, like food delivery workers, within specific social and cultural contexts.
Substitution or addition: An observational study of a new primary care initiative in the Netherlands
Authors: van den Bogaart Esther HA , Spreeuwenberg Marieke D , Kroese Mariëlle EAL , Ruwaard Dirk
Published: January 2023

Objective

In 2014, the Primary Care Plus (PC+) model was introduced in the Netherlands to shift low-complex specialised care from the hospital to the primary care setting. While positive effects of PC+ have been documented at individual patient level concerning health-related quality of life, perceived quality of care and care costs, its impacts on service use at the population level remain uncertain.

Methods

In this observational study, we used retrospective health insurance reimbursement claims data from the largest health insurer in the intervention region to determine service use. We assessed PC+ and secondary care insurance claims (i.e. claims of the regional hospital and claims of other secondary care settings in and outside the region visited by patients from the intervention region) from 2015 to 2018 and compared these to the national level.

Results

The total number of claims related to low-complex specialised care in the intervention region showed an increase over time. The increase in claims was related to PC+. The number of claims related to the regional hospital and other secondary care settings decreased over time. During the same period, a declining trend in claims at the national level was observed.

Conclusion

The introduction of the PC+ model in one region in the Netherlands was associated with an increase in the use of low-complex specialised care. This suggests that the ability of the PC+ model to substitute for specialist care at population level may be limited. Going forward, it will be important to continue monitoring and evaluating service use as substitution effects may materialise only over a longer timeframe.
Experimental detection of train wheel defects using wayside vibration signal processing
Authors: Salehi Mehdi , Bagherzadeh Seyed Amin , Fakhari Mohamad
Published: January 2023

While many studies have been used onboard monitoring methods to detect train wheel defects, this paper aims to extract damage features from vibrational signals obtained by the wayside monitoring system. To provide an appropriate tool for the decomposition of experimental nonstationary vibration signals containing impacts, an analytical amplitude-based signal decomposition method is provided. A two-axle motor car with a flat wheel defect is studied at different operating conditions. Vibrational signals arising from wheel-rail interactions are gathered by the Wayside Data Collection Setup (WDCS) with five piezoelectric accelerometers. The tests are performed at the constant speeds of 10, 20, 30, and 40 km/h. The acquired signals are decomposed by the Multi-channel Singular Spectrum Analysis (MSSA) into the contributing components. Based on the results, increases in the amplitudes of the second reconstructed components (RCs) of the vibrational signals sensed by all the accelerometers can be observed at a specific time instance as a repeating pattern. Similar patterns are obtained at different motor car positions relative to the measurement area, as well as different motor car speeds. To verify the consistency of the second RCs, the crest factors are obtained for all the angular positions. The results show sudden increases in the crest factor at a fixed angular position that indicate the existence of a defect at that specific angular position of the wheel.

Published: January 2023

Valid, meaningful, and reliable adult retrospective measures of violence against children (VAC) are essential for establishing the prevalence, risk factors, and long-term effects of VAC. We aim to summarize the available evidence on the psychometric properties of adult retrospective VAC measures and to provide evidence-based recommendations for appropriate measure selection. We searched six electronic databases and gray literature for studies that report on the development, content validity, or psychometric properties of adult retrospective child abuse and neglect measures for this review (PROSPERO: CRD4201706). We used the 2018 Consensus-based Standards for the selection of health Measurement Instruments (COSMIN) criteria to evaluate each included study and measure. We assessed if measures included questions on frequency or severity, the perpetrator, or the location of the violence, and noted the administrative practicalities for each instrument such as length, readability, available translations, and cost to access. We identified 288 studies and 77 measures. The quality of evidence ranged from “low” to “high,” depending on the measure and the psychometric properties assessed. The measures with the most robust evidence available across multiple contexts are the: ACE and ACE-IQ; FBQ and FBQ-U; CTQ and CTQ-SF; and ICAST-R. This review shows the strengths and weaknesses of retrospective VAC measures. The substantial evidence presented in this review can be used by researchers to make psychometrically sound decisions for measurement selection which should be supported by extensive piloting and adaptation to the respective local context.
Study on dynamic characteristics of drill string in deep-water riserless drilling
Authors: Huang Fangfei , Yang Jin , Li Bin , Gan Lunke , Feng Qizeng
Published: January 2023

The cost and security of ocean drilling are directly related to the efficient exploration and development of ocean resources. The riserless drilling system is usually adopted in the ocean drilling. With the consideration of marine environment load, a dynamic analysis model of drill string in deep-water riserless drilling is established. This model aims to analyze the dynamic characteristics of drill string in the water and down hole during the process of deep-water riserless drilling. The research results are as follows. For the drill string in water, its displacement increase with the increase of ocean current velocity, water depth, rotation speed, and WOB. But the rotation speed and WOB have less influence. The drill string in down hole shows the same pattern. However, the drill string in down hole is only affected near the mud line and the bit, and the rest of the drill string is almost unaffected. In deep-water riserless drilling, stress on the drill string at the wellhead, near the mudline, and at the bottom hole assembly (BHA) is complex. The safety of drill string at these locations should be given great attention.

Published: January 2023

Objectives

Acute lower extremity ischemia is one of the most common emergencies in vascular surgery and is a cause of considerable morbidity and mortality. The goal of this study was to evaluate outcomes of revascularization for acute lower extremity ischemia and to determine factors associated with perioperative morbidity and mortality.

Methods

A total of 354 patients underwent urgent revascularization for acute lower extremity ischemia at an academic medical center between 2014 and 2019. A retrospective review of patients’ demographics, comorbidities, etiology and severity of limb ischemia, and procedural characteristics was recorded. Outcomes, including postoperative complications, perioperative limb loss, and mortality, were analyzed.

Results

The mean patient age was 69 ± 17 years, and 52% were females. 50% of patients presented with Rutherford Class IIb ischemia. Arterial embolization was the most common cause of limb ischemia, seen in 33% of cases. Open surgical revascularization was performed in 241 (68%) patients, while endovascular and hybrid approaches were utilized in 53 (15%) and 60 (17%) cases, respectively. Postoperative adverse events occurred in 44% of patients, including wound complications (11%), cardiac (5%) and pulmonary (16%) complications, strokes (4%), UTIs (10%), renal failure (14%), bleeding (5%), and compartment syndrome (3%). The rate of unplanned return to the operating room was 21%. Major adverse cardiovascular events were seen in 103 (29%) patients and major adverse limb events were seen in 57 (16%) patients. The median length of stay was 10 days (IQR = 4); 49% patients were discharged to skilled nursing facility and 19% were readmitted within 30 days. The rate of amputation during index admission was 10%, and perioperative mortality was 20%. Gender, tibial runoff, and etiology of limb ischemia were independent predictors of limb loss. Women had lower risk of limb loss than men (OR, 0.11; 95% CI, 0.023, 0.38). Poor tibial runoff (one-vessel or absence of flow below the knee) was a significant predictor of limb loss as compared to three-vessel runoff (OR, 14.92; 95% CI, 1.92, 115.88). Aneurysmal disease (OR, 38.35; 95% CI, 3.54, 42.45) and traumatic injuries (OR, 108.08; 95% CI, 8.21, 159.06) were the strongest predictors of amputation as compared to other etiologies of limb ischemia. Multivariate model identified ESRD (OR, 9.2; 95% CI, 1.8–46.3), degree of ischemia (class IIb or higher vs class IIa; OR, 3.5; 95% CI, 1.2–10.6), and age (OR, 1.5; 95% CI 1.1–2.0 for every 10 years) as independent predictors of perioperative mortality.

Conclusions

Urgent revascularization for management of acute limb ischemia is associated with high morbidity and mortality. Elderly patients with ESRD presenting with severely threatened limbs have especially high risk of perioperative mortality and may not be ideal candidates for limb salvage.
Middle leaders’ sensemaking of their leadership practices in response to educational disruption: A Q-methodology study
Authors: Chaaban Youmen , Sawalhi Rania , Lundberg Adrian
Published: January 2023

Middle leaders were required to navigate the complexities of educational disruption and respond to internal and external demands throughout the pandemic. This shifting educational context necessitated a sensemaking process to better understand and act on the issues which gave rise to ambiguities in their school environment. This study investigated the sensemaking processes employed by 27 middle leaders from 20 government schools in Qatar, at a time when COVID-related restrictions had been lifted and face-to-face learning had resumed. To collect and analyze data, Q-methodology was applied. A 34-statement Q-sample was developed based on a proposed conceptual framework of sensemaking during times of disruption which included three dimensions: intrapersonal, relational, and institutional. Q-factor analysis revealed two significantly different viewpoints regarding how participants enacted certain practices in response to educational disruption. These were (1) sensemaking as a relational endeavor and (2) sensemaking as an agentic endeavor. The two viewpoints differed in sources of sensemaking and its mechanisms. Sensemaking offered a useful theoretical construct as it revealed middle leaders’ perceptions and enactments, and their struggles in maintaining a balance between structure and agency. The study has implications for middle leadership policy and practices in times of educational disruption and beyond, with its distinctive methodological and contextual contributions.
Collective care and climate repair
Authors: Osborne Natalie
Published: January 2023

This engagement with Chantel Carr's article, ‘Repair and care: Locating the work of climate crisis’, considers possible organising structures of care and climate repair, and the ways this labour can work to reproduce or to challenge settler-colonial capitalist states. Drawing on critical disability studies and crip theory, this essay considers alternative imaginaries of mutual aid and care that can inform how we conceive of and organise the work of climate repair without relying on ‘emergency’ and ‘crisis’ to propel us, and while, at all times, centring justice.
A rare case of rapidly progressive atrial myxoma masquerading as cough syndrome

Primary cardiac tumors are rare; however, atrial myxoma is one of the most common benign cardiac tumors. Myxomas may arise from any of the cardiac chambers but have a predilection for the left atrium. Its manifestations may mimic left heart failure or pulmonary hypertension either by causing blood flow obstruction or by mitral regurgitation. Patients can also present with thromboembolic features. Often, the diagnosis may be missed or delayed due to subclinical cardiac manifestations. Prompt diagnosis and surgical resection is necessary for favorable prognosis. Often, mitral valve replacement may be needed. We report a rare case of rapidly growing atrial myxoma in a 39-year-old female who presented with progressively worsening shortness of breath and cough with a previously normal echocardiogram 8 months prior. Her symptoms resolved after surgical resection and mitral valve replacement.
Civic Engagement Intention and the Data-Driven Fan Community: Investigating the Motivation Behind Chinese Fans’ Online Data-Making Behavior From a Collective Action Perspective
Authors: He Qijun , Li Yungeng
Published: January 2023

Enabled by social media, the data frenzy in the data-driven fandom culture in China has attracted widespread attention. Unlike most forms of data labor and fan activities, Chinese fans’ online data-making behavior ( zuoshuju) appears tedious, time- and money-consuming, and overwhelmingly irrational. Therefore, this study aimed to examine the sociopsychological motivation of fans’ online data-making behavior from a collective action perspective. Based on survey data from 588 respondents with fandom experiences online in China, this study (1) distinguished two types of online data-making (operational and monetary); (2) suggested that celebrity worship and civic engagement intention were antecedents of online data-making; and (3) found that fan communities facilitated by social media bridged the effects of sociopsychological factors and data-making behavior. This research introduced the collective action perspective and constructed a quantitative path model to test the underlying mechanism and impetus of fans’ data-making practices in China, adding quantitative support to the knowledge of the hybrid pattern of collective actions embedded in the datafication world. It contributes to the understanding of Chinese youth culture and civic engagement through social media.

This cross-sectional study aimed to determine the correlation between the coping styles and depression, anxiety, and stress levels of individuals living in Turkey during the COVID-19 pandemic. The study was conducted using an online questionnaire (Socio-demographic Form; Depression, Anxiety, and Stress Scale-21; Coping Styles Scale) and it included 483 individuals. Descriptive statistics, ANOVA, Independent Samples t-test, Kolmogorov-Smirnov, Hosmer-Lemeshow and Scheffe tests, Pearson Correlation, and Binary Logistic Regression analyzes were used to analyze the data. There was a negative correlation between the participants’ self-confident and optimistic coping styles mean scores and their depression, anxiety, and stress mean scores. There was a positive correlation between the participants’ helpless, submissive, and seeking social support coping styles mean scores and their depression, anxiety, and stress mean scores. The regression analysis revealed that using the helpless coping style increased the depression, anxiety, and stress levels of the participants while using the optimistic coping style and visiting a physician during the pandemic decreased them. In addition, seeking social support coping style increased the level of depression while the testing during the pandemic increased stress levels. As a result, it is recommended to strengthen society’s psychological resilience and expand mental health support services for such mental illnesses.
