Method for Assessing the Motor Coordination of Runners Based on the Analysis of Multichannel EMGs
Authors: Sun Ren , Su Shuijun , He Quantao
Published: May 2023

In this paper, we propose a method to evaluate the motor coordination of runners based on the analysis of amplitude and spatiotemporal dynamics of multichannel electromyography. A new diagnostic index for the coordination of runners was proposed, including the amplitude of electromyography, the spatiotemporal stability coefficient, and the symmetry coefficient of muscle force. The motor coordination of 13 professional runners was studied. Detailed anthropometric information was recorded about the professional runners. It has been found that professional athletes are characterized by the stability of movement repetition (more than 83%) and the high degree of symmetry of muscle efforts of the left and right legs (more than 81%) regardless of the changes in load during running at a speed of 8–12 km/hr. Scientific and technological means can support the scientific training of athletes. The end of the Winter Olympic Games has shown us the powerful power of a series of intelligent scientific equipment, including electro-magnetic gun, in sports training. We also look forward to the continuous innovation of these advanced technologies, which will contribute to the intelligent development of sports scientific research.
Incomplete Multiview Clustering via Low‐Rank Tensor Ring Completion
Authors: Yu Jinshi , Huang Haonan , Duan Qi , Wang Yafei , Zou Tao
Published: May 2023

Since real‐world multiview data frequently contains numerous samples that are not observed from some viewpoints, the incomplete multiview clustering (IMC) issue has received a great deal of attention recently. However, most existing IMC methods choose to zero‐fill the missing instances, which leads to the failure to exploit information hidden in the missing instances, and high‐order interactions between various views. To tackle these problems, we proposed an effective IMC method using low‐rank tensor ring completion, which was demonstrated to be powerful in exploiting high‐order correlation. Specifically, we first stack the incomplete similarity graphs of all views into a 3rd‐order incomplete tensor and then restore it via the tensor ring decomposition. Next, using an adaptive weighting technique, we apply multiview spectral clustering to all entire graphs in order to balance the contributions of different viewpoints and identify the consensus representation for grouping. Finally, we employ the alternating direction method of multipliers (ADMM) to optimize the suggested model. Numerous experimental findings on numerous different datasets show that the suggested approach is superior to other cutting‐edge approaches.

Published: May 2023

The main objective of the present study is to evaluate the multicriteria group decision-making problem in risk management for technological innovation projects (TIPs) under dual-probabilistic linguistic information. The suggested approach is based on an enhanced dual probabilistic linguistic-vise kriterijumska optimizacija kompromisno resenje (DPL-VIKOR) technique to assess risk management in TIP employing probabilistic linguistic information. The conventional VIKOR approach is incapable of dealing with the complexity and difficulty of risk assessment in TIP. Therefore, we incorporated the information included in the dual probabilistic linguistic term set. In DPL-VIKOR, we investigated the relationship between the positive ideal solution (PIS) of the alternative and the negative ideal solution (NIS). To deal with the multicriteria group decision-making problem of risk assessment in TIP, we proposed the extended DPL-VIKOR approach rather than the traditional VIKOR method. We compared the findings to those of several decision-making problem techniques and examined the effectiveness and reliability, as well as advantages of the proposed approach. From the comparison and sensitivity analysis, we conclude that the proposed method is more reliable and effective for evaluating the best alternative in risk management problems for TIP.
Improved Ant Colony Optimization for the Operational Aircraft Maintenance Routing Problem with Cruise Speed Control
Authors: Zhang Qing , Chan Felix T. S. , Fu Xiaowen
Published: May 2023

The operational aircraft maintenance routing problem (OAMRP) plays a critical part in producing considerable cost reductions for airlines, since its solution directly influences the number of operating leased aircraft. To reduce the quantity of required aircraft, adopting cruise speed control in OAMRP is a good strategy. In this paper, we investigate the OAMRP with cruise speed control. The objective is to minimize the required quantity of aircraft by finding the optimal aircraft routes through cruise time optimization. The focus is on solving two issues simultaneously: (i) optimization of cruise times and (ii) determination of aircraft routes. Since the combination of two intricate sets of decisions poses significant methodological challenges, the difficulty lies in how to efficiently solve it. Accordingly, the goal of this study is twofold: (i) to design a preprocessing step to reduce the network size and (ii) to develop an improved ant colony optimization (IACO) algorithm with a new state transition mechanism to provide the guidance for cruise times optimization and a new pheromone updating mechanism to enhance the search efficiency and precision. Using data from the Bureau of Transportation Statistics (BTS), we demonstrate the computational efficiency of the preprocessing step and the IACO algorithm.

Published: May 2023

Objective. The emergence of carbapenemase-producing Enterobacterales (CPE) is a major concern that is increasingly reported worldwide. Our study aimed at investigating the resistance of CPE isolates in a Moroccan teaching hospital using phenotypic and genotypic methods. Methods. Enterobacterales strains from March to June 2018 were collected from different clinical samples. The Enterobacterales isolates resistant to third-generation cephalosporins (3GC) and/or carbapenems were subjected to the Carba NP test and an immunochromatographic test for phenotypic detection. Detection of extended-spectrum β-lactamases (ESBL) was also performed following standards. Molecular screening of carbapenemases genes (OXA-48, NDM, blaKPC, blaIMP, blaVIM, and blaOXA-24, blaOXA-23, OXA-51, OXA-58) using conventional multiplex PCR assays was also performed on 143 isolates. Results. Enterobacterales represented 52.7% with a proportion of 21.8% of bacteria resistant to 3GC and/or carbapenems. Within 143 isolates MDR to 3GC, K. pneumoniae, E. coli, and E. cloacae represent 53.1%, 40.6%, and 6.3%, respectively. These strains were isolated mainly from urinary samples (74.8%) in patients admitted to emergency and surgical units. 81.1% of strains are producing ESBL and 29% are carbapenemase producers as confirmed by the Carba NP test, immunochromatographic test, and molecular testing. OXA-48 carriers represent 83.3% of these strains, followed by NDM with 16.7%. blaKPC, blaIMP, blaVIM, and blaOXA-24, blaOXA-23, OXA-51, OXA-58 were not detected in any of these bacteria. Conclusions. A high rate of CPE carrying OXA-48 among Enterobacterales resistant to 3GC and/or carbapenems isolates was found. Strict observance of hospital hygiene measures and more rational use of antibiotics are mandatory. Implantation of carbapenemases detection should be encouraged in our hospital settings to estimate the true burden of the CPE.

Published: May 2023

Honey is one of the important food commodities due to its nutritional and medicinal values. However, the issue of its quality and authenticity remain as important factors in consumption and marketing. This study was aimed at determining the botanical sources and quality parameters of honey samples collected from different areas of Ethiopia. The botanical sources of honey were analyzed using the melissopalynological method. Sugar profiles were analyzed using HPLC, and physicochemical properties were determined following the harmonized methods of honey analysis. Diverse plant species, including Schefflera abyssinica, Eucalyptus spp., Guizotia abyssinica., Echinops spp., Coffee arabica, Bersama abyssinica, and Rumex spp., were identified as dominant sources of honey. However, honey from the Gimbo district contains no pollen fingerprints, and its source has remained unknown. The average values of honey sugar compositions ranged from 30.3–46.7%, 29.9–40.3%, 15.0–22.2%, and 0.28–4.4% for fructose, glucose, sucrose, and maltose, respectively. Although the quality parameter values of most honeys fit the acceptable range of national and international honey quality standards, honeys collected from Guassa district revealed some abnormal characteristics. This abnormality may be related with poor handling, processing, or suspected for honey adulteration. Thus, regular testing and monitoring of honey quality are crucial in order to maintain its natural properties as well as control the current widespread practice of honey adulteration in Ethiopia.
How to Turn a Hero into a Comic miles
Authors: Speriani Silvia
Published: May 2023

This paper aims, on the one hand, at contributing to the analysis of one of the most enduring stock-characters in Roman comedy: the comic soldier, in its Plautine manifestations in particular. On the other hand, it will shed light on a much more serious soldier: Telamonian Ajax, and his in some way unfortunate reception. Weaving a twofold discussion of such apparently distant figures, I will evaluate the possible echoes of the mighty warrior Ajax in the parodic processes enacted by Plautus’ milites, as well as the role played in turn by these echoes in the Roman reception of Ajax himself. I will show how the Roman Ajax enhanced and developed comic nuances, which can be better understood through the trigger of Plautine memories and play a role in Rome’s own reflection on everchanging criteria for measuring valour.
Case Mortier V. Belgium: The Balance Between the Right to Life and the Right to Respect for Private Life in the Light of Euthanasia
Authors: Walraet Paulien
Published: May 2023

The case Mortier v. Belgium is the first case where the Court comments on the figure of euthanasia. The area of euthanasia in particular raises the issue of finding a balance between the protection of the patients’ right to life in Article 2 of the Convention and that of the right to respect for his or her private life and personal autonomy in Article 8 of the Convention. The Court confirmed the States must be afforded a margin of appreciation in finding this balance. However, it does not concern an unlimited margin as the Court reserved its power to review the States fulfilment of its obligations under Article 2. After deciding that there had been no breach of article 8 in the performing of euthanasia as such, the Court examined the positive obligation of Belgium to foresee in sufficient safeguards to protect the right to life.
Developmental Machinery in the Third District of Pangasinan and in Naga, Camarines Sur: An Exploratory Comparison
Authors: Eusebio Gerardo V.
Published: May 2023

This article investigates how political machineries and direct delivery of developmental goods and services to crucial constituencies were being linked and used in two locales in the Philippines: Third Congressional District of Pangasinan and the City of Naga. In the context of the “developmental machinery,” differences in the two areas’ respective contexts create distinct yet similar machinery and outcomes in terms of both political and socioeconomic development. Utilizing archival research and comparative analysis, this article aims to compare the two experiences in running political machines that are based more on direct people’s participation and direct delivery of goods and services. Preliminary evidence shows that the two are most likely unique political structures that were similarly founded on the principles of broad public participation and credible service delivery. More research is needed to flesh out the comparison, as well as the “model” of developmental machinery.
Risk Factors for Unplanned Returns to the Operating Room in Pediatric Trauma Patients
Authors: Sea Jessica , Grigorian Areg , Swentek Lourdes , Chin Theresa , Goodman Laura F. , Guner Yigit , Nahmias Jeffry
Published: May 2023

Background

Unplanned returns to the operating room (uROR) are associated with worse outcomes including increased complications and length of stay (LOS) in adults. However, the incidence and predictors of uROR for pediatric trauma patients (PTPs) are unknown. This study aimed to identify predictors of uROR for PTPs.

Methods

The 2017-2019 Trauma Quality Improvement Program database was queried for PTPs 1-16 years-old to compare patients with uROR to those without uROR. Multivariable logistic regression analysis was performed.

Results

From 44 711 PTPs identified, 299 (.7%) underwent uROR. Pediatric trauma patients requiring uROR were older (14 vs 8 years old, P < .001), had a higher rate and associated risk of mortality (8.7% vs 1.4%, P < .001) (OR 6.67, CI 4.43-10.05, P < .001) as well as increased complications including surgical infection (16.4% vs .2%, P < .001) and compartment syndrome (4.7% vs .1%, P < .001). Patients undergoing uROR had increased LOS (18 vs 2 days, P < .001) and intensive care unit LOS (9 vs 3 days, P < .001). Independent associated risk factors for uROR included rectal injury (OR 4.54, CI 2.28-9.04, P < .001), brain injury (OR 3.68, CI 2.71-5.00, P < .001), and gunshot wounds (OR 2.55, CI 1.83-3.56, P < .001).

Discussion

The incidence of uROR was <1% for PTPs. However, patients requiring uROR had increased LOS and associated risk of death compared to those without uROR. Predictors of uROR included gunshot wounds and injuries to the rectum and brain. Patients with these risk factors should be counseled with efforts made to improve care for these high-risk populations.
A Single Center Experience With Bilateral Wilms Tumor
Authors: Chen Stephanie Y. , Lee William G.H. , Laifman Eric , Mack Shale J. , Zhou Shengmei , Kim Eugene S.
Published: May 2023

Background

Wilms tumor (WT) is the most common pediatric renal malignancy and bilateral disease (BWT) occurs in 5% of cases and is associated with poor outcomes. Management of BWT includes chemotherapy and oncologic resection while preserving renal function. Previous literature has demonstrated variable approaches in BWT treatment. The aim of this study was to examine a single institution experience and outcomes with BWT.

Methods

A retrospective chart review was performed for all patients with WT treated at a free-standing tertiary children’s hospital between 1998 and 2018. Patients with BWT were identified and treatment courses were compared. Outcomes of interest included need for dialysis post-operatively, need for renal transplantation post-operatively, disease recurrence, and overall survival.

Results

Of 120 children with WT, 9 children (6F:3M) of median age 32 months (IQR: 24-50 months) and median weight 13.7 kg (IQR: 10.9-16.2 kg) were diagnosed with and treated for BWT. Pre-operative biopsies were obtained in 4/9 patients, 3 of whom received neoadjuvant chemotherapy and 1 who underwent radical nephrectomy. Of the 5 patients who did not undergo biopsy, 4/5 were treated with neoadjuvant chemotherapy, and 1/5 underwent upfront nephrectomy. Post-operatively, 4/9 children required dialysis, of whom 2 subsequently underwent renal transplantation. Two patients were lost to follow-up, and of the remaining 7 patients, disease recurrence occurred in 5/7 children and overall survival was 71% (n=5).

Conclusion

Management of BWT varies regarding the use of pre-operative biopsy, neoadjuvant chemotherapy, and extent of disease resection. Further guidelines on treatment protocols may optimize outcomes in children with BWT.
An Ounce of Prevention is the Only Cure: Nationwide Clinical and Financial Outcomes of Self-Inflicted Firearm Injuries
Authors: Tran Zachary , Bonnick Kristine , Byun Julianne , Cho Nam Yong , Benharash Peyman , Mukherjee Kaushik
Published: May 2023

Background

Self-inflicted gunshot wounds (SIGSWs) remain a leading, preventable cause of death in the United States. The present study evaluated patient demographics, operative characteristics, in-hospital outcomes, and resource utilization between patients with SIGSW and other GSW.

Methods

The 2016-2020 National Inpatient Sample was queried for patients ≥16 years old admitted following gunshot wounds. Patients were categorized as SIGSW if they were injured through self-harm. Multivariable logistic regression was used to evaluate the association of SIGSW on outcomes. The primary endpoint was in-hospital mortality with complications, costs, and length of stay secondarily considered.

Results

Of an estimated 157,795 surviving to hospital admission, 14,670 (9.30%) were SIGSW. Self-inflicted gunshot wounds were more commonly female (18.1 vs 11.3%), insured by Medicare (21.1 vs 5.0%), and white (70.8 vs 22.3%) (all P < .001) compared to non-SIGSW. Psychiatric illness was more prevalent in SIGSW (46.0 vs 6.6%, P < .001). Additionally, SIGSW more frequently underwent neurologic (10.7 vs 2.9%) and facial operations (12.5 vs 3.2%) (both P < .001). After adjustment, SIGSW was associated with greater odds of mortality (AOR: 12.4, 95% CI: 10.4-14.7). Length of stay (β: +1.5 days, 95% CI: .8-2.1) and costs (β: +$3.6 K, 95% CI: 1.4-5.7) were significantly greater in SIGSW.

Conclusions

Self-inflicted gunshot wounds are associated with increased mortality compared to other GSW, likely due to the increased proportion of injuries in the head and neck region. This lethality, coupled with the high prevalence of psychiatric illness in this population, indicates that efforts must be made to intervene through primary prevention, including enhanced screening and weapon safety considerations for those at risk.
The Effect of Propofol on Peri-Induction Hemodynamics and Resuscitation in Operative Penetrating Trauma
Authors: Levin Jeremy H. , Wallace Marshall W. , Hess T. Noel , Beavers Jennifer R. , Chang Tony , Beyene Robel T.
Published: May 2023

Background

Hemorrhaging trauma patients may be disproportionately affected by choice of induction agent during rapid sequence intubation (RSI). Etomidate, ketamine, and propofol are safe in the trauma population-at-large but have not been assessed in patients with ongoing hemorrhage. We hypothesize that in hemorrhaging patients with penetrating injury, propofol deleteriously affects peri-induction hypotension compared to etomidate and ketamine.

Methods

Retrospective cohort study. Primary outcome was the effect of induction agent on peri-induction systolic blood pressure. Secondary outcomes were the incidence of peri-induction vasopressor use and quantity of peri-induction blood transfusion requirements. Linear multivariate regression modeling assessed the effect of induction agent on the variables of interest.

Results

169 patients were included, 146 received propofol and 23 received etomidate or ketamine. Univariate analysis revealed no difference in peri-induction systolic blood pressure (P = .53), peri-induction vasopressor administration (P = .62), or transfusion requirements within the first hour after induction (PRBC P = .24, FFP P = .19, PLT P = .29). Choice of RSI agent did not independently predict peri-induction systolic blood pressure or blood product administration. Rather, only presenting shock index independently predicted peri-induction hypotension.

Conclusions

This is the first study to directly assess the peri-induction effects of anesthetic induction agent choice in penetrating trauma patients undergoing emergent hemorrhage control surgery. Propofol does not appear to worsen peri-induction hypotension regardless of dose. Patient physiology is most predictive of peri-induction hypotension.
The Activists Who Divide Us: A Cross-Country Analysis of Party Activists’ Influence on Polarization and Representation
Authors: Amitai Yair
Published: May 2023

What explains party polarization in multiparty systems? This study turns the spotlight to intraparty mechanisms, namely, the authorities and influence of party activists over the candidate selection process, as a potential source of party-system polarization. I hypothesize that parties in which activists possess more comprehensive selection authorities, the party elite will hold more extreme ideological positions, catering to activists' representation demands. Additionally, in such cases, the ideological gap between party elites and voters will be larger since more extreme actors overshadow the preferences of moderate party voters. Aggregating the intraparty effect of activists to the party-system level, I expect to find higher level of party polarization in countries where more parties allocate selection authorities to activists. Utilizing party-level data regarding candidate selection procedures as well as public opinion and elite position data from 19 countries and 93 parties between 2011 and 2017, I find support for my hypotheses.
Examining Parent-Child Contact Practices Among Incarcerated Parents With Mental Health Illnesses
Authors: Ahlin Eileen M. , Derlic Dragana , Kokkalera Stuti
Published: May 2023

While there is a growing body of research on parent-child visitation among the general carceral population, less attention has been paid to examining parent-child contact practices among parents with mental health illness diagnoses. The current study uses a sample from the 2016 Survey of Prison Inmates to analyze the associations between mental health illness diagnosis and various modalities of parent-child contact. Multivariate analyses of types of mental health illness diagnoses on six parent-child contact modalities demonstrate heterogeneity where not all mental health diagnoses reduce all parent-child contacts. Furthermore, incarcerated parents with multiple mental health illnesses are less likely to experience most forms of contact including in-person visits, phone calls, and mail.
Explaining Changes in Threat Appraisal, Coping Appraisal, and Flood Risk-Reducing Behavior Using Panel Data From a Nation-Wide Survey in Germany
Authors: Bubeck Philip , Osberghaus Daniel , Thieken Annegret H.
Published: May 2023

Protection Motivation Theory (PMT) has become a widely-used theoretical framework to explain the risk-reducing behavior of individuals toward flooding and other natural hazards. Despite a quickly growing body of literature applying PMT in the context of flooding, insights into changes in PMT components and risk-reducing behavior are largely lacking due to a predominant use of cross-sectional research designs. In this study, we examine how various intrapersonal sources of information relate to changes in PMT components and risk-reducing behavior, using unique panel data ( n = 2,680) from a survey in Germany and a fixed-effects regression modeling approach. In line with PMT, we find that various intrapersonal sources of information, like prior experience, relate to changes in PMT components. We also find that coping appraisals of PMT change in a direction negatively related to risk-reducing behavior over time, posing a challenge for risk communication and the envisaged shift to integrated flood risk management.
An effective hybrid algorithm for joint scheduling of machines and AGVs in flexible job shop
Authors: Wen Xiaoyu , Fu Yunzhan , Yang Wenchao , Wang Haoqi , Zhang Yuyan , Sun Chunya
Published: May 2023

Flexible job shops motivated by small batches and multiple orders require the collaboration of machines and automated guided vehicles (AGVs) scheduling to boost shop floor flexibility and productivity. The joint scheduling of machines and AGVs can better achieve global optimization. However, joint scheduling requires two NP hard problems to be solved simultaneously. Therefore, this paper employs a multi-AGV flexible job shop scheduling problem (MA-FJSP) with an effective hybrid algorithm. First of all, a model is established with the objectives of minimizing the makespan, the total AGV running time and the total machine load. To solve the MA-FJSP, high-quality initialization methods and improved elite strategies are designed to improve global convergence in the proposed algorithm. In addition, a problem-knowledge-based neighborhood search is integrated to improve its exploitation capability. At last, a series of comparative experimental studies were performed to exam the effectiveness of the improved algorithm. The results demonstrate that the solutions gained by the proposed algorithm perform well in respect of convergence, diversity and distribution.
Preventive Epidemiology of PrEP Use in African American Women With a Perceived HIV Risk
Authors: Guinn Dominique , Espinoza Luis Enrique
Published: May 2023

This study aims to examine the impact of education and household income on African American women’s perception of HIV risk on PrEP use. Secondary data from the Be-PrEPared dataset on 202 African American women’s attitudes toward condom use, biomedical prevention strategies, and risks associated with HIV transmission. African American women with a greater level of education and a perceived risk of HIV were more likely to utilize PrEP than African American women with a lower level of education and no reported risk of HIV. Additionally, women with a higher household income and perceived HIV risk were more likely to use PrEP as well. These associations were still present when taking HIV knowledge into account. It is the job of health practitioners and public health/health education professionals to improve PrEP interventions to be more culturally competent which will make adults more cognizant of the health issues related to HIV infection.
Uncertainty quantification in free vibration and aeroelastic response of variable angle tow laminated composite plate
Authors: Sharma Narayan , Swain Prasant Kumar , Maiti Dipak Kumar
Published: May 2023

The influence of uncertainty in material properties on free vibration and aeroelastic response of variable angle tow (VAT) laminated plates is presented in this work. Free vibration analysis is conducted by a finite element model based on third-order shear deformation theory. The FE model is further coupled with MSC. Nastran to carry out aeroelastic analysis of VAT laminates in the subsonic regime. MSC. Nastran helps to extract the aerodynamic influence coefficient matrix at discrete values of reduced frequencies using Doublet Lattice Method. The accuracy and adaptability of the highly efficient radial basis neural network (RBFN) based surrogate model developed for uncertainty analysis are checked by comparing the result with that of the Monte Carlo simulation. Stochastic analysis of natural frequencies and flutter characteristics of VAT laminates are conducted through various parametric studies. Variance-based sensitivity analysis is used to calculate the contribution of individual material properties to the free vibration and aeroelastic response of VAT laminates. Further, the influence of the highly sensitive properties on the structural failure probability is estimated. This research can be leveraged to predict the probability of failure of the structure at different levels of material uncertainty present in it.
Decentralized event-triggered resilient control for a class of networked control systems under denial-of-service attacks
Authors: Torabi Amir , Zarei Jafar , Saif Mehrdad
Published: May 2023

This paper studies the problem of resilient dynamic output-feedback control schemes for continuous-time networked control systems (NCSs). A decentralized hybrid strategy is utilized while network imperfections, external disturbances, and noise are considered. Moreover, during data transmission, a practical denial-of-service (DoS) jamming attack, which periodically disturbs the network channels, is considered. To preserve the network resources, a decentralized event-triggered mechanism is employed to transmit only the sampled signals that are required. It is assumed that outputs and control inputs of each subsystem are transmitted to the corresponding decentralized controllers and actuators, respectively, over the different individual channels based on independent triggering mechanisms. At first, the NCS is modeled as a decentralized hybrid system with exogenous disturbance and noise. Then, sufficient conditions that guarantee the [Formula: see text]-stability of the NCS in the presence of external disturbances and noise, which is resilient to periodic DoS attacks, are provided in terms of the linear matrix inequalities. Finally, sufficient conditions are derived to deal with the time-varying delays. It has been demonstrated that the proposed technique can be effectively applied to a well-known continuous stirred tank reactor (CSTR) as a benchmark example.

Authors: Yakubova Gulnoza , Chen Briella Baer , Al-Dubayan Monerah N. , Gupta Stuti
Published: May 2023

The purpose of this study was to examine the effects of an online multi-component intervention (video modeling, virtual manipulatives, digital games, self-monitoring and least to most prompting techniques) on the acquisition of several mathematical skills of two autistic elementary school students. We used a multiple probe design of a single-case experimental design across three skills and two autistic elementary students to examine whether a causal relation existed between the intervention and children’s skill acquisition. Both children reached 100% accuracy on all skills by the end of the intervention phase and showed some evidence response generalization and maintenance. The findings add to limited research on online instructional practices in teaching mathematics to autistic children. The intervention involving the use of video modeling instructional clips, virtual manipulatives, guided practice via mathematics games along with self-monitoring and least to most prompting strategies has the potential to help autistic children improve their mathematical skills in a virtual instructional setting.
Interpersonal variables and caregiving partners' burden in cardiac illness: A longitudinal study
Authors: Katz Eran , Bar-Kalifa Eran , Pietromonaco Paula , Wolf Hodaya , Klempfner Robert , Hod Hanoch , Vilchinsky Noa
Published: May 2023

The literature on coping with illness has for many years viewed only the patients as the focal point of attention and support, and only recently have the needs of patients’ caregivers been acknowledged as well. In addition, studies that have focused on factors contributing to caregiving partners’ burden in the context of chronic illness have assessed mostly intrapersonal variables of either the patient or the partner, thus overlooking the dyadic and interpersonal nature of caregiving. In the current longitudinal study, we examined the contribution of interpersonal factors, such as patients’ and partners’ relationship satisfaction and social support perceptions, to caregiving partners’ burden in the context of cardiac illness. Couples comprising male patients and female caregiving partners ( N = 131) completed measures of relationship satisfaction, provided support, and received support upon patients’ admission to a cardiac rehabilitation program after an acute cardiac event (Time 1), and 3 months later (Time 2), upon program completion. Caregiving partners also completed a measure of burden at both measurement times. Path analyses revealed that partners’ relationship satisfaction, provided support, and received support, were all associated with lower levels of different dimensions of burden at both timepoints, as well as over time. Patients’ contribution to their partners’ burden was salient cross-sectionally but not over time. The findings shed light on the substantial role played by interpersonal factors in the caregiving process. Our findings suggest that both patients and partners should be regarded as caregivers and care receivers to each other.
Decolonizing Voices From Rojhelat: Gender-Othering, Ethnic Erasure, and the Politics of Intersectionality in Iran
Authors: Mohammadpour Ahmad
Published: May 2023

The state murder of Jîna Amini, a 22-year-old Kurdish woman in Tehran on 16 September 2022, while in custody of the Islamic Republic’s morality police, prompted a widespread uprising across Iran unprecedented in scale since the popular 1979 revolution. Adopting the Kurdish catchphrase ‘Jin, Jîyan, Azadî’ (Woman, Life, Freedom), this movement was largely centered in Kurdistan (known as Rojhelat) and Balochistan, two ethnically minoritized and economically de-developed regions, where the state deployed deadly violence and brutality to crush the protests. This article juxtaposes two competing narratives of this uprising. The first insists on branding the movement as a singular ‘national’ uprising of ‘Iranian women’. The second recognizes a plurality of women, particularly those from marginalized nations, such as Kurdish and Balochi women, and underlines the structural national, ethnoreligious, and linguistic oppression elided in the narrative of undifferentiated Iranian womanhood. Drawing on the notion of intersectionality, I argue that the elite nationalist discourse of Iranian womanhood reproduces the state’s ethnoreligious and linguistic suppression of non-Persian-speaking marginalized communities. Moreover, such a selective reading of gender inequality in Iran is unable and/or unwilling to embrace the intersectionality and multiplicity of women’s life experiences in Iran, particularly in its ethnic peripheries. This article offers a critical reassessment of Iranian feminism and its methodology of privilege, proposing instead a decolonized approach that invites nationalist Persian/Iranian activists to interrogate Persianness as a marker of official national identity and institutionalized supremacy.
Impact of the Local and the Global Crises on Stock Market Efficiency
Authors: Bhatia Madhur
Published: May 2023

The study examines the evolution of the stock market efficiency of Indian banks during the period from 1 January 2007 to 30 June 2022. The study also seeks to investigate the degree of the impact of the different crises on the stock market efficiency in response to three major events: the global financial crisis, the local banking crisis and the pandemic crisis. For this, the wild bootstrap automatic variance ratio (WBAVR) test is applied using the rolling window method to account for the implications of the adaptive market hypothesis (AMH). For the robustness of the analysis, the study applies the automatic portmanteau (AQ) test, which is also based on a data-driven procedure. The findings show that the market efficiency of Indian banks is not an all-or-nothing phenomenon; rather, both efficiency and inefficiency co-exist simultaneously, with the Central Bank of India noted to be the most ‘inefficient’ bank. The findings demonstrate that market efficiency is ‘context-dependent’, that is, the stock market efficiency significantly alters in response to black-swan events happening in the economy. The study sheds light on the degree of the impact of different events on market efficiency, and it is shown that the internal crisis of the industry of high NPAs has a far greater impact on market efficiency compared to the global financial and pandemic crises. This research may assist policymakers in developing a comprehensive strategy to enhance the stock market efficiency of Indian banks in the face of such local and global crises.
The Effects of Team Reflexivity and Gender-Role Attitudes on Female Nurses
Authors: Chang Wen-Ying , Lee Yi-Hsuan
Published: May 2023

Taiwan has significantly fewer senior nursing personnel than many other countries, which can be attributed in part to the prevalence of interpersonal stress and same-sex conflicts that often arise in female-dominated workplaces such as nursing. This study explored how team reflexivity and gender-role attitudes influence the stay intent of female nursing personnel using a cross-sectional design. Results showed group-level team reflexivity has more positive impact on nurses’ stay intent via team-based self-esteem than individual perceived team reflexivity, but traditional gender-role attitudes weaken this impact. Our findings indicate mutual understanding and trust is crucial for nursing teams to function effectively.

Background:

Symptomatic osteochondral lesions of the talus (OLTs) often require surgical intervention. There are various surgical methods. A generally valid, stage-dependent therapeutic algorithm does not exist. The aim of our study is to show long- term results of an alternative technique that combines retrograde drilling, debridement performed under arthroscopic visualization, and autologous bone grafting.

Methods:

The surgical technique was performed in 24 patients with medial or lateral OLTs, and the data were analyzed retrospectively. In our technique, the affected subchondral bone was overdrilled retrogradely and resected under arthroscopic visualization (ossoscopy) without violating the cartilage. The resulting defect was filled with autologous bone from the medial tibia metaphysis. Outcome parameters were the numeric rating scale (NRS), the American Orthopaedic Foot & Ankle Society (AOFAS) ankle-hindfoot score, and range of motion (ROM). The Magnetic Resonance Observation of Cartilage Repair Tissue (MOCART) score was assessed and a possible correlation with the clinical outcome scores was calculated. Data concerning complication rates were also collected.

Results:

The mean surface size of the OLTs was 0.9 ± 0.3 cm2. The mean follow-up was 89 months. The AOFAS score improved significantly from 57.7 points preoperatively to 88.8 points at the final follow-up ( P < .0001). The pain value measured by the NRS decreased significantly from 8 to a pain level of 2. ROM improved in 37.5% of the patients for dorsiflexion and 29.2% for plantarflexion. There were no significant correlations between the MOCART score and the AOFAS score or the pain value on NRS.

Conclusion:

Retrograde drilling, ossoscopy, and autologous bone grafting for OLTs is a promising technique with good long-term results. The patients’ satisfaction rate, especially in OLT stages 2 and 3, was excellent.

Background:

Posterior tibial tendon (PTT) tendoscopy and medializing calcaneal osteotomy (MCO) are among the available techniques for patients presenting with symptomatic flexible hindfoot valgus (stage IA) progressive collapsing foot deformity (PCFD). The aim of this study was to determine clinical and radiographic outcomes of combined PTT tendoscopy and MCO for patients presenting with symptomatic stage IA PCFD.

Methods:

A retrospective cohort study was performed in order to determine clinical and radiographic outcomes of 30 combined PTT tendoscopies and MCO on 27 patients presenting with symptomatic stage IA PCFD, with a minimum follow-up of 24 months. Patient satisfaction was assessed at last available follow-up as very satisfied, satisfied, and unsatisfied. Clinical assessment was performed evaluating preoperative and last available follow-up visual analog scale for pain (VAS-P), Foot and Ankle Outcome Score (FAOS), and the 36-Item Short Form Health Survey (SF-36). Magnetic resonance imaging (MRI) was performed preoperatively on all patients. Standard weightbearing anteroposterior, lateral, and long axial view radiographs of the foot and ankle were taken preoperatively, immediate postoperatively, at 6 weeks, 3 months, 6 months, 1 year postoperatively, and last follow-up evaluation available for each patient.

Results:

The mean follow-up was 38.6 (range, 26-62) months. We registered 27 very satisfied, 1 satisfied, and 2 unsatisfied patients. There was statistically significant improvement on all clinical scores (VAS-P, FAOS and SF-36), as well as on lateral talo–first metatarsal and hindfoot alignment angles. We found low-grade PTT tears in 5 patients (16.67%) in whom preoperative MRI documented PTT tenosynovitis alone.

Conclusion:

We found that combined PTT tendoscopy and MCO provide significant clinical and radiographic improvement for patients presenting with symptomatic stage IAB PCFD. PTT tendoscopy should be considered in the treatment of all surgically addressed flexible valgus feet as it detects tendon tears which are frequently missed on an MRI.

Multiple drug-resistant Escherichia coli ( E. coli) is a serious cause of concern, and they can be observed in hospital settings, natural environment, and animals. Dissemination of multiple drug-resistant (MDR) E. coli can pose a high risk to public health. Moreover, they are hard to control with commercial antibiotics, since they have acquired resistance against most of them. Therefore, to control multiple drug-resistant bacteria, alternative strategies have been adopted such as phage therapy, herbal remedies, nanoparticles etc. In the current study, the combined application of neem leaf extract and bacteriophage is used to control an isolated multiple drug-resistant E. coli E1. We have applied 0.1 mg/ml concentration of neem extract in combination with an isolated phage vB_EcoM_C2 of 1011 titer and found that the combinatorial treatment approach significantly controls the growth of E. coli E1 as compared to a single non-combinatorial treatment. In this study, every E. coli cell is targeted by 2 antimicrobials (phage and neem extract) at the same time, which is more effective as compared to the sole treatment. Implementation of the neem extract with phage opens a new alternative approach to the chemotherapeutics for the control of multiple drug-resistant bacterial pathogens. This approach may be effective, economical, and eco-friendly to combat MDR.
The digital divide in the journalism sector
Authors: Mellor Noha
Published: May 2023

This article argues that the digital sphere has maintained the offline hierarchal forms of political, economic, and cultural powers, taking the Arab journalism sector as a topical case study. The article explores the potential of digital platforms as a new source of revenue for Arab news media and a new site for disseminating informative content that helps push the freedom of speech in the region. It demonstrates the difficulty of achieving either goal partly due to the monopoly of Big Tech over the digital advertising market and partly due to the competition among Arab media outlets to use clickbait content to lure audiences and hence increase superficial metrics such as clicks and shares. The article draws on different forms of evidence, including articles penned by Arab journalists, in which they reflect on their experiences in the digital sphere, papers by Arab scholars, in addition to informal conversations with selected Arab journalists.

Published: May 2023

Background

Disruptive Mood Dysregulation Disorder was included in DSM-5 to accommodate new research addressing aspects of emotional dysregulation in children suffering from disruptive behavior problems. Despite growing interest in Disruptive Mood Dysregulation Disorder, few studies have looked at prevalence rates in European clinical populations. The primary objective of this study was to examine the prevalence and characteristics associated with Disruptive Mood Dysregulation Disorder in a Norwegian clinical sample.

Methods

The present study assessed children 6–12 years of age referred to a mental health clinic for evaluation and treatment ( N = 218, M age = 9.6, 60.4% boys) and compared those who did and did not meet Disruptive Mood Dysregulation Disorder diagnostic criteria. Diagnoses were determined using K-SADS-PL 2013. Associated difficulties at home and in school were measured by Achenbach Systems of Empirically Based Assessment battery.

Results

In this clinical sample, 24% met the diagnostic criteria for Disruptive Mood Dysregulation Disorder. Children with Disruptive Mood Dysregulation Disorder were more likely than those without Disruptive Mood Dysregulation Disorder to be male (77% vs. 55%, p = .008), be living in poverty, have multiple mental health diagnoses (79% vs. 53%, p = .001), and have lower global functioning levels as measured by Children’s Global Assessment Scale (range 0–100, M = 47, SD = 8.5 vs. M = 57, SD = 11.4, p=<.001). Finally, parents and teachers of children with Disruptive Mood Dysregulation Disorder reported lower overall competence and adaptive functioning, and higher total symptom load than children with other diagnoses.

Conclusion

Disruptive Mood Dysregulation Disorder is highly prevalent in a Norwegian clinical sample and displays a high symptom load. Our results are in accordance with similar studies. Consistent findings across the world may support Disruptive Mood Dysregulation Disorder as a valid diagnostic category.
Development of a multichannel spectral simulation tool and experimental validation with different lighting scenarios

Published: May 2023

The spectral composition of light has been linked to various non-image-forming responses besides visual photoreception. Accordingly, simulation tools must incorporate the spectral composition of light to account for such responses. A simulation tool was developed which uses N-step algorithm and subdivides the (red, green, and blue) RGB bands into multiple channels. This research intends to validate the tool for different lighting scenarios. A physical model was constructed in which the integral irradiance from 380 nm to 780 nm was measured for three scenarios: diffuse daylight, electric light with variable correlated colour temperature and a combination of both. All three scenarios were simulated with 3, 9, 27 and 81 channels. For scenarios with electric light and combination of daylight and electric light, the nine-channel simulation improved the mean absolute percentage error (MAPE) by 13.9% to 33.9% compared to the three-channel simulation. For continuous daylight, there was only a small improvement of 0.4% when increasing from 3 to 27 channels. In comparison to 9 channels, 27 channels slightly improved MAPE in all the scenarios but substantially increased the simulation time. Increasing the number of channels to 81 is likelier to bring a contribution to more complex scenarios than that presented in this study.
