Loneliness, age at immigration, family relationships, and depression among older immigrants: A moderated relationship
Authors: Jang Heejung , Tang Fengyan
Published: December 2021

Guided by a convoy model of social relations, this study explores the complex relationships between loneliness, age at immigration, familial relationships, and depressive symptoms among older immigrants. This study used 2010 Health and Retirement Study data from a sample of 575 immigrants (52% female, age range 65–99 years). Ordinary least squares regression models were estimated. The findings indicate that for older immigrants who came to the United States at age 45 or older, loneliness was significantly positively associated with depressive symptoms. Further, perceived negative strain and hours spent helping family moderated this relationship such that the effect of loneliness on depressive symptoms was stronger among respondents who perceived more negative family strain and spent fewer hours helping family. Familial relationships are crucial for the psychological well-being of older immigrants because they can be a source of either stress or support. The results have implications for how research and practices can support the immigrant families.
Curiosity Emerging From the Perception of Change in Music
Authors: Omigie Diana , Ricci Jessica
Published: December 2021

Music offers a useful opportunity to consider the factors contributing to the experience of curiosity in the context of dynamically changing stimuli. Here, we tested the hypothesis that the perception of change in music triggers curiosity as to how the heard music will unfold. Participants were presented with unfamiliar musical excerpts and asked to provide continuous ratings of their subjective experience of curiosity and calm, and their perception of change, as the music unfolded. As hypothesized, we found that for all musical pieces, the perceptual experience of change Granger-caused feelings of curiosity but not feelings of calm. Our results suggest music is a powerful tool with which to examine the factors contributing to curiosity induction. Accordingly, we outline ways in which extensions to the approach taken here may be useful: both in elucidating our information-seeking drive more generally, and in elucidating the manifestation of this drive during music listening.
United States Civil Reserve Air Fleet (CRAF): A Brief History—Formation, Functionality, and Future
Authors: Gallagher Robert E. , Burch Gerald F. , Batchelor John H.
Published: December 2021

Air mobility has been a military strategic advantage used by the United States (U.S.) from the onset of aircraft carriers, to supporting air bases worldwide. The U.S. government and defense components rely heavily on a civilian fleet of aircraft to supplement air transportation requirements in both peace times and during national emergencies. This paper reviews the historical and legal development of the Civil Reserve Air Fleet (CRAF) and discusses previous struggles and successes of the program by looking at the functionality of the program, before addressing how current events bring about the realization that the program must change. Current changes in the way U.S. airlines operate, the way warfare has been changed, and the financial hardships associated with the COVID-19 pandemic are all used to envision a future of the CRAF program to provide future air transportation capabilities to allow the U.S. government to maintain the necessary strategic advantage of responsive airlift capabilities.
Identification of Operational Design Domain for Autonomous Truck Mounted Attenuator System on Multilane Highways
Authors: Tang Qing , Hu Xianbiao , Yang Hong
Published: December 2021

The Autonomous Truck Mounted Attenuator (ATMA) vehicle system is a technology that leverages connected and automated vehicle (CAV) capabilities for maintenance of transportation infrastructure. Promoted by FHWA and state departments of transportation (DOTs), it is a niche CAV application in leader–follower style, intended to remove DOT workers from the following maintenance truck, to reduce fatalities in work zones. Because practicable guidance for deployment of this technology is largely missing in MUTCD, state DOTs have been making their own deployment criteria. In this manuscript, we focus on the operational design domain (ODD) problem—under what traffic conditions should ATMA be deployed. Modeling efforts are first focused on the derivation of an effective discharge rate that can be associated with a moving bottleneck caused by slow-moving ATMA vehicles on a multilane highway. Then, based on the demand input and discharge rates, microscopic traffic flow models calculate vehicle delay and density, which the Highway Capacity Manual (HCM) suggests are key indicators of a multilane highway’s level of service (LOS). In this way, the linkage between AADT and LOS is analytically established. NGSIM data is used for the model validation and shows that the developed model correctly captures the effective discharge rate discount caused by moving bottlenecks. The modeling results demonstrate that roadway performance is sensitive to the K factor and D factor, as well as the operating speed of ATMA and, if LOS = C is a desirable design objective, a good AADT threshold to use would be around 40,000 vehicles per day.
Contributions of Reality TV Consumption to College Women’s Endorsement of the Heterosexual Script and Acceptance of Sexualized Aggression
Authors: Papp Leanna J. , Ward L. Monique , Marshall Riley A.
Published: December 2021

A prominent feature of mainstream television, especially reality programming, is a heterosexual script that outlines women’s and men’s traditional courtship roles. Although frequent media use is believed to produce greater acceptance of this script, existing analyses have not fully delineated contributions of scripted versus reality programming or tested these notions using a holistic heterosexual script scale. We addressed these limitations in two studies. In Study 1, 466 undergraduate women indicated their support of the heterosexual script and their consumption of popular reality programs, sitcoms, and dramas. Heavier viewing of reality programming predicted greater support for the heterosexual script, and heavier viewing of sitcoms predicted weaker support. In Study 2, we used longitudinal data to explore relations between viewing reality television, acceptance of the heterosexual script, and acceptance of sexualized aggression during undergraduate women’s first 2 years in college ( N = 244). We found that reality television consumption was not a direct predictor of acceptance of sexualized aggression but was a significant, indirect predictor through endorsement of the heterosexual script. These studies contribute to our understanding of unique media contributions to endorsement of the heterosexual script and illuminate one process by which women may come to normalize sexual mistreatment. Campus educational programming on sexuality, sexual assault, and healthy relationships may be able to intervene in this normalization through critique of the heterosexual script and media portrayals of dating and relationships.

An Introduction, Review, and Conceptual Analysis of Mattering as an Essential Construct and an Essential Way of Life
Authors: Flett Gordon L.
Published: December 2021

While the importance of having self-esteem is widely recognized and has been studied extensively, another core component of the self-concept has been relatively neglected—a sense of mattering to other people. In the current article, it is argued that mattering is an entirely unique and complex psychological construct with great public appeal and applied significance. The various ways of assessing mattering are reviewed and evidence is summarized, indicating that mattering is a vital construct in that deficits in mattering are linked with consequential outcomes at the individual level (i.e., depression and suicidal tendencies), the relationship level (i.e., relationship discord and dissolution), and the societal level (i.e., delinquency and violence). Contemporary research is described which shows that mattering typically predicts unique variance in key outcomes beyond other predictor variables. Mattering is discussed as double-edged in that mattering is highly protective but feelings of not mattering are deleterious, especially among people who have been marginalized and mistreated. The article concludes with an extended discussion of key directions for future research and an overview of the articles in this special issue. It is argued that a complete view of the self and personal identity will only emerge after we significantly expand the scope of inquiry on the psychology of mattering.
Evaluation of the Effectiveness of an Empathy Training on Empathy Skills, Life Satisfaction, and Relationship Quality for Chinese Adolescents and Their Mothers: A Mixed Methods Study
Authors: Chen-Bouck Li , Patterson Meagan M. , Qiao Bixi , Peng Anqi
Published: December 2021

Using a pre- and post-test design, this study examined the changes in empathy skills, life satisfaction, and relationship quality among mainland Chinese adolescents (ages 13–15 years) and their mothers ( N = 108 dyads) following an empathy training intervention. Participants completed a 20-day empathy training, including two in-person group training sessions and daily journals on assigned topics. Participants’ mother-child relationship quality, mother-child conflict, life satisfaction, and empathy skills were measured three times, and selected participants were interviewed to explore their experience of the training. The research procedure followed protocols that were approved by an Institutional Review Board. ANOVAs were used to examine quantitative data and inductive analysis was used for qualitative data. The findings suggest that after the training, both adolescents and mothers reported significant benefits in mother-child relationship quality and life satisfaction. However, participants’ empathy skills (i.e., perspective taking and empathic concern skills) did not change. Possible mechanisms of the observed changes included the empathy skills (e.g., perspective taking skills) learned through the training and the reciprocal nature of positive changes within the mother-child dyad. The current study suggests that empathy training may benefit adolescents and their mothers, both within the relationship and in their general life satisfaction.
Exploring the Perceptions of Nurses on Receiving the SARS CoV-2 Vaccine in Palestine: A Qualitative Study
Authors: Belkebir Souad , Maraqa Beesan , Nazzal Zaher , Abdullah Abdullah , Yasin Ferial , Al-Shakhrah Kamal , Zink Therese
Published: December 2021

Background

Uncertainty about vaccination among nurses are major barriers to managing the ongoing COVID-19 pandemic worldwide.

Purpose

To explore nurseś perceptions about receiving the SARS CoV-2 vaccine to inform the upcoming Palestinian Ministry of Health (MOH) vaccination efforts.

Methods

Four focus groups were conducted with nurses between January 18 and 30, 2021, before MOH launched vaccinations in Palestine. Participants working in government and private facilities were invited to participate and completed an online or paper form to provide demographics, review the study purpose, and give consent. Meetings were facilitated in Arabic either online via the Zoom platform or face-to-face using the same interview guide. Transcripts were translated into English and coded using a template analysis approach.

Results

Forty-six nurses, with a median age of 29.5y (range, 22–57) from across Palestine participated. Three major themes emerged: uncertainty, trust, and the knowledge needed to move forward. Uncertainty related to the evolving nature of COVID-19, the rapidity of vaccine development, the types and timing of available vaccines. The need for trusted experts to share scientific information about the vaccines to counteract the misinformation in social media. Moreover, reliable vaccine information may help vaccine-hesitant nurses move to vaccine-acceptors and to convince others, including their patients.

Conclusion

The negative perception of nurses towards vaccines is problematic in Palestine and uncertainty about which vaccine(s) will be available adds to the lack of education and mass-media misinformation. Other countries with vaccination efforts that are not wholly planned or implemented and may be struggling with similar concerns.
Impact of Focused Deterrence on Lived Experiences With Gangs and Gun Violence: Extending Effects Beyond Officially Recorded Crime
Authors: Kochel T. R , Nouri Seyvan , Samadi S. Yaser
Published: December 2021

The study evaluates a geographically based focused deterrence (FD) intervention, extending knowledge about FD impact beyond crime data to also examine residents’ lived experiences with gangs and gun violence via a two-wave household survey. We employ a quasi-experimental design and utilize time-series analyses, coefficient difference tests, and mixed-effects ordinal logistic regression. The results show a significant reduction in shots fired incidents in the target area relative to comparison areas. Shots fired calls for service trended downward citywide, but the magnitude was doubled in the target area. Survey data showed substantive declines in the target area on all six gang and gun violence outcomes, significantly exceeding changes experienced in comparison areas. We conclude that focusing geographically as well as on repeat offenders is an effective FD approach, and evaluating community surveys provides an improved understanding of the community impact.
Neoliberal Fatigue: The Effects of Private Refugee Sponsorship on Canadians’ Political Consciousness
Authors: Elcioglu Emine Fidan
Published: December 2021

Private sponsorship has become a primary way that refugees access resettlement to Canada. Key in this program are the private Canadians who volunteer their money, time, and labor to sponsor and support refugees. Drawing on 25 interviews, this article examines the insights that these privileged citizens of the global north gain as they help refugees struggling with the marginalizing consequences of neoliberal austerity in their new hostland. While sponsors learn about the challenges facing working-class racialized newcomers (otherwise obscured to sponsors by their racial, class, and citizenship privileges), the program robs sponsors of the time and mental bandwidth to reflect on the structural nature of these challenges. Consequently, sponsors rarely understand refugees’ struggles as public troubles necessitating broader intervention, including modest policy reform. I call this cognitive outcome neoliberal fatigue. I conclude by discussing how this fatigue thwarts social change and reinforces neoliberal capitalism.
Alfred Vierkandt’s notion of the social group
Authors: Segre Sandro
Published: December 2021

German sociologist Alfred Vierkandt is hardly remembered today. This may seem surprising. Several prominent sociologists from the German-speaking countries contributed to the Handwörterbuch der Soziologie (1931), which Vierkandt edited and published. However, Vierkandt did not interact with any of them significantly, and this publication brought no recognition of the importance of his sociological oeuvre in Germany, the United States, or elsewhere. His key notion of the social group found no acknowledgment among other contemporary or later sociologists, even though several of them used this notion and discussed social groups in their own writings. Moreover, those who paid close attention to his writings, like Abel and Hochstim, evaluated them quite critically. Both before and after World War II, Vierkandt remained a solitary and relatively unknown author.
Looking Back To Venture Forward: Exploring Idea and Identity Work in Public Failure Narratives
Authors: Saylors Rohny , Lahiri Amrita , Warnick Benjamin , Baid Chandresh
Published: December 2021

Business failure often leads entrepreneurs to craft public narratives. Taking a performative storytelling perspective of such narratives, we investigate how entrepreneurs jointly reevaluate their ideas and identities, and how this relates to their subsequent career paths. We theorize that the stories entrepreneurs tell shape who they become, changing not only how others see them but also how they see themselves. This broadens theoretical understanding of how failed entrepreneurs navigate their transition to a diverse array of subsequent careers, including different forms of serial entrepreneurship (same industry; new industry) and exit (startup employee; established business employee; exit with reentry).
In-plane dynamic buckling of duoskelion beam-like structures: discrete modeling and numerical results
Authors: Turco Emilio , Barchiesi Emilio , dell’Isola Francesco
Published: December 2021

In this contribution, a previously introduced discrete model for studying the statics of duoskelion beam-like structures is extended to dynamics. The results of numerical simulations performed using such an extended model are reported to discuss the in-plane dynamic buckling of duoskelion structures under different loading and kinematic boundary conditions. The core instrument of the analysis is a discrete beam element, which, in addition to flexure, also accounts for extension and shearing deformations. Working in the setting of dynamics, inertial contributions are taken into account as well. A stepwise time integration scheme is employed to reconstruct the complete trajectory of the system, namely before and after buckling. It is concluded that the duoskelion structure exhibits exotic features compared with classical beam-like structures modeled at macro-scale by Euler–Bernoulli’s model.
Complementary and normalized energies during static and dynamic uniaxial deformation of single and multi-layer foam-filled tube
Authors: Mirbagheri Seyed Mohammad Hossein , Salehi Mina
Published: December 2021

This article investigates the quasi-static compressive behavior and the drop weight impact tests during the crashing of energy-absorbing structures such as aluminum foam-filled tubes. The closed-cell Al and A356 Alloy foams were cast and, after cutting, inserted into the Al thin wall tube as axial fillers of single-, double- and quad-layer structures. Then, the specific energy absorption (SEA), complementary energy (CE), normalized energy (NE), and specific normalized energy (SNE) are calculated based on static and dynamic test results under uniaxial loading. In this new method, values of NE and SNE are always between 0 and 1. Results show that the SEA-strain curves obtained from crashing the foam-filled tubes were linear and overlapping under static and dynamic loading. However, NE curves for dynamic tests were cyclic and in the static tests were asymptotic non-linear, and utterly separable. Results indicated that the SNE for Al, A356 single layer, Al-A356 double-, and Al-A356-Al-A356 quad-layer foam-filled tubes during dynamic tests were 0.25, 0.29, 0.31, and 0.31, while for the static tests, 0.14,0.15, 0.17, and 0.14 were recorded. It was found that CE and NE energies were better than the SEA energy for recognizing plastic deformation and crushing behavior.
Sheathless use of Supera stent minimizes access complications in antegrade femoral puncture: Technical note with case series
Authors: Aprigliano Gianfranco , Giupponi Luca , Palloshi Altin , Glavina Fabio , Morici Nuccia
Published: December 2021

Antegrade femoral puncture (AFP) is the preferred strategy to treat lower limb obstructive disease. However, the presence of vascular calcification may be associated with procedure related adverse events, impairing endovascular device strategies. We describe a case series of superficial femoral and popliteal artery treatments by Supera stent implantation using a simple technique to significantly minimize the dimension of the antegrade femoral puncture from 6 to 4 French (Fr). All antegrade femoral punctures, crossing femoro-popliteal lesion and predilation were made with 4 Fr introducer. After preparation the Supera stent was navigated in sheathless fashion via 0.018-inch guidewire. Postdilation and final control were made replacing the 4 Fr introducer via the same guidewire. A good final result was achieved. Patients were discharged early without any complications. This minimally invasive technique in cases of infrainguinal peripheral artery disease could be feasible and effective for minimizing the risk of complications in patients with critical limb ischemia.
Is Cytoreductive Surgery Possible in Cervical Cancer Peritoneal Carcinomatosis?
Authors: Duzgun Ozgul , Kalin Murat
Published: December 2021

Background:

The number of cases of cervical cancer with recurrence and peritoneal carcinomatosis is limited. In our study, we aimed to present the results of cytoreductive surgery hyperthermic intraperitoneal chemotherapy treatment and its 3-year early period results in patients with peritoneal metastases due to cervical cancer.

Methods:

Data of 306 patients who had undergone cytoreductive surgery hyperthermic intraperitoneal chemotherapy between May 2016 and 2021 because of intra-abdominal metastases were collected prospectively and evaluated retrospectively. Ten cases who had undergone cytoreductive surgery plus hyperthermic intraperitoneal chemotherapy due to cervical peritoneal carcinomatosis were included in this study.

Results:

Average time of operation was 5 (range = 3-6) hours, mean average of peritoneal carcinomatosis index score was 12.3 (range = 7-36), and mean average of completeness of cytoreduction score was 1 in 2 patients and 0 in 8 patients. No mortality was recorded in 30 days postoperatively. Four patients relapsed and died because of pneumonia, coronavirus disease, pulmonary embolism, and terminal illness. These patients died at 2, 5, 6, and 12 months, respectively. Six patients are still alive and early period tumor relapse has not been reported during their follow-ups.

Conclusions:

This study has a limited number of patients and the results are early period results. The follow-up of patients were not long term. Therefore, it is hard to say that cytoreductive surgery hyperthermic intraperitoneal chemotherapy could be of any benefit looking at the results. Long-term results should be waited. Also, multicentered randomized cohort study with large sample size is required to evaluate this invasive procedure.
Pseudo-seizure, an Atypical Presentation of Attention-Deficit Hyperactivity Disorder in a Female: A Case Report
Authors: Yong Qun Leow Timothy , Sadhu Raja , Mayall Mark , McDermott Brett , Botha Bianca , Yiallourides Michalis , Mongia Monica
Published: December 2021

Background

This paper describes pseudo-seizure as an atypical presentation of attention-deficit hyperactivity disorder (ADHD) in an adolescent female in the context of psychosocial difficulties. We present the case, which explains the clinical dilemma in such situations, along with selective literature review.

Case Presentation

An adolescent female, who is an academic high achiever, living with parents, presented with unresponsive spells which were initially treated with antiepileptics by the paediatrician without any significant improvement. Later, after further assessments and revision of her diagnosis to conversion disorder, she was referred to the child and youth mental health service team. Further evaluation revealed her symptoms to be a result of multiple psychosocial stressors in the context of her having undiagnosed ADHD. Individual therapy, treatment with stimulant, resulted in significant improvement in her school and home adjustments.

Conclusions

This case demonstrates the diagnostic challenges that high-functioning girls with ADHD coloured by psychosocial stressors can pose and raises the need for reviewing our diagnostic approaches in these situations.
The impact of online reviews on destination trust and travel intention: The moderating role of online review trustworthiness
Authors: Su Lujun , Yang Qingyue , Swanson Scott R , Chen Ning Chris
Published: December 2021

This study explores the impact of the valence (positive/negative) and emotional intensity (strong/weak) of online reviews on potential Chinese visitors’ travel intentions and trust of a destination. An experimental design was used to test the hypotheses. Findings suggest that online review valence and emotional intensity affect travel intentions and that destination trust can partially mediate this relationship. Changes in destination trust and travel intention due to positive/negative review emotional intensity changes are not equivalent. Furthermore, online review trustworthiness moderates the valence and destination trust and travel intention relationships, but not the effect of review emotional intensity on the same outcomes.
Gazing on invisible men: Introducing the gallery gaze to establish that (in)visibility is in the eye of the beholder at Westminster Menswear Archive
Authors: Bluteau Joshua M
Published: December 2021

The Westminster Menswear Archive, housed at the University of Westminster held an exhibition in 2019 entitled ‘Invisible Men’. The purpose of this show was to “shine a light” on men, or more accurately menswear which had been hitherto neglected by scholarship and exhibitions featuring dress (Groves and Sprecher, 2019). This article draws on research conducted at this exhibition to ask anthropological questions as to the nature of menswear both in the gallery space and beyond. Fundamentally this will question the invisible nature of menswear and whether such invisibility really exists. In order to accomplish this, this article will suggest a new theory of the gaze that exists in the gallery or exhibition space – the gallery gaze – and use it to provoke analysis of the ethnographic material presented. This article acknowledges a distinction between intellectual, semiotic and symbolic invisibility but suggests a different approach, arguing for an (in)visibility of progressive degrees.
The perception of stakeholders regarding the outcomes achieved by schools with high or low levels of effectiveness and high numbers of immigrant students
Authors: Intxausti-Intxausti Nahia , Oregui-González Eider , Azpillaga-Larrea Verónica
Published: December 2021

The aim of this study was to characterize those schools in the Autonomous Community of the Basque Country (Spain) with high numbers of immigrant students in accordance with their effectiveness level (high or low). Three effectiveness criteria (scores, residuals, and times) were used to select the schools, resulting in three models: a ceiling or floor effect model, a contextualized cross-sectional model, and a contextualized longitudinal model. Of the 524 initial schools analyzed, 7 were found to have high or low effectiveness levels and higher-than-average immigration levels. Following the selection, the discourses of 40 education stakeholders were analyzed through semi-structured interviews and discussion groups. The results highlight the strong sense of vulnerability felt in some schools, as well as the general conviction that greater support, commitment, and stable, collaborative leadership by the management team and inspectorate would contribute to improving effectiveness.
Shear-flexural cracking strength of RC beams with external vertical prestressing rebars: Theoretical investigation and numerical simulation
Authors: Junlong Zhou , Dongsheng Li
Published: December 2021

This paper presents a semi-theoretical empirical formula to predict the shear-flexural cracking strength of an RC beam enhanced with the external vertical prestressing rebar (EVPR) technique. Besides, nonlinear finite element models (FEM) created by software ABAQUS were used to analyze the effect of crucial parameters on the shear-flexural cracking strength. The parameters involve shear span-to-depth ratio, concrete strength, longitudinal tension reinforcement ratio, initial pulling force and spacing of EVPRs, and the vertical stiffness of the EVPR supports. Results show that the cracking strength increased linearly with the tensile strength of the concrete and the initial pulling force. The small shear span-to-depth ratio was predominantly conducive to the cracking strength. Adequate longitudinal tension rebars contributed to the cracking strength improvement. A reasonable EVPR spacing was recommended to ensure the cracking strength. Greater vertical stiffness of the EVPR supports can ensure higher compressive stress for the RC beam to improve the cracking strength.
Modeling and control of hybrid MR seat damper and whole body vibration evaluation for bus drivers
Authors: Munyaneza Olivier , Sohn Jung Woo
Published: December 2021

This paper describes the design, simulation, and performance evaluation of hybrid MR damper on quarter bus semi-active seat suspension coupled with human biodynamic model. Also, the whole body vibration (WBV) exposures were evaluated based on the international standard ISO 2631 (1997), and its parameters were used to measure the level of discomfort for bus drivers. The hybrid MR damper was proposed to enhance the damping force within low current supplied and achieve a fail-soft capability in case of electrical failure. The characteristics of the proposed hybrid MR damper were compared to the conventional MR damper by considering the same size, materials, and current input. The designed damper was incorporated to seat suspension system coupled with biodynamic lumped model, and the governing equations of motion of the full model were derived. Skyhook controller was used to control the amount of current to be supplied to hybrid MR damper. The controlled semi-active hybrid MR and conventional MR seat suspension are compared to uncontrolled system for two types of road excitation. The simulated results show that the driver seat comfort was improved by the skyhook controller than the uncontrolled case. The evaluated WBV showed that the hybrid MR damper can improve the driver life from fairly uncomfortable to little discomfort.
Experimental studies on interlaminar shear strength and dynamic mechanical analysis of luffa fiber epoxy composites with nano PbO addition
Authors: Ashok Kumaresan Gladys , Kani Kalaichelvan
Published: December 2021

In the present study, the significance of nanofiller lead oxide (PbO) on the dynamic mechanical analysis (DMA) and interlaminar shear strength (ILSS) performance of luffa fiber–reinforced epoxy composites was investigated. The epoxy matrix was altered with nanofiller PbO of different weight percent through a mechanical stirring process. The PbO-added luffa fiber epoxy composites were made through hand layup preceded by the compression molding method. The prepared composite samples were investigated for ILSS and DMA. The test results lead to the inference that the 1.25 wt% PbO nanofiller–added composite samples attained 25%, 17%, and 55% of higher loss modulus, storage modulus, and ILSS, respectively, as compared with the other prepared samples. The morphological investigation was conducted on the fractured surface of the interlaminar tested samples. The micrographic images show the bonding nature of the luffa fiber with the epoxy matrix, fiber breakage, and fiber pullouts. The characterization studies such as FTIR, XRD, and EDX were conducted on the fabricated composite samples. The XRD studies show that the rise in weight percent of the nanofiller PbO enhances the crystallinity of the composite samples. Moreover, the composite sample prepared with 1.25 wt% nanofiller PbO can be used to prepare low-cost roofing materials for sustainable housing projects.

Aplastic or twig-like middle cerebral artery and cardiogenic cerebral embolism mimicking moyamoya disease with RNF213 polymorphism: A case report
Authors: Inoue Hiroyasu , Oomura Masahiro , Nishikawa Yusuke , Mase Mitsuhito , Matsukawa Noriyuki
Published: December 2021

Progressive stenosis and occlusion of the bilateral internal carotid artery terminals and circle of Willis are typical features of Moyamoya disease. However, aplastic or twig-like middle cerebral artery (Ap/T-MCA)—wherein the unilateral main trunk of the middle cerebral artery (MCA) is not depicted, and a plexiform arterial network is formed—is similar to the findings of Moyamoya disease. Here, we describe a 78-year-old man who presented with mild right paralysis and aphasia. Magnetic resonance angiography (MRA) at admission did not show the bilateral MCAs. The findings were similar to those of Moyamoya disease, and his symptoms worsened after hospitalization. Endovascular treatment was performed, and the left MCA was completely recanalized. Later, paroxysmal atrial fibrillation was detected, and we finally determined that left MCA occlusion had occurred due to embolism. The right MCA was completely occluded at its origin, indicating an Ap/T-MCA. Embolic occlusion of the unilateral MCA and contralateral Ap/T-MCA made this case resemble Moyamoya disease in the acute stage. Even when chronic occlusion is suspected on MRA in acute cerebral infarction, endovascular treatment should be considered. Additionally, a heterotypic R4810K polymorphism was later found in the RNF213 gene. To our knowledge, this is the second report of Ap/T-MCA with the RNF213 gene polymorphism; however, their association remains unclear and requires further analyses.
Effects of acute exercise intensity on source episodic memory and metamemory accuracy
Authors: Loprinzi Paul , Rigdon Brandon , Javadi Amir-Homayoun , Kelemen William L.
Published: December 2021

Prior research suggests that behavioural (e.g., exercise) and psychological factors (e.g., metamemory; monitoring and control of one’s memory processes) may influence memory function. However, there is conflicting results on the optimal intensity of acute exercise to enhance memory and whether acute exercise can also enhance metamemory. Furthermore, very limited research has evaluated whether acute exercise can influence source episodic memory. The objective of this study was to evaluate whether there is an intensity-specific effect of acute exercise on source episodic memory and metamemory accuracy. Thirty young adults participated in a three-condition (control/moderate/vigorous-intensity exercise), within-subject counterbalanced experimental study. After each intervention, participants completed source episodic memory and metamemory tasks. Results demonstrated that acute exercise, relative to control, was effective in enhancing source episodic memory, but not metamemory accuracy. Vigorous-intensity acute exercise was the most optimal intensity to enhance source episodic memory. Overall, our findings suggest that there is an intensity-specific effect of acute exercise on source episodic memory. Furthermore, when exercise-related improvements in memory occur, young adults may be unaware of these memory benefits from exercise.
Agreement between the American Shoulder and Elbow Surgeons Society Standardized Shoulder Assessment score (ASES) and the Oxford Shoulder Score (OSS) in patients presenting with shoulder pathology: A cohort analysis of the Clinical Quality Registry for Outcomes in Shoulder and Elbow Pathology (CROSEP) registry
Authors: Teoh Wesley WH , Scholes Corey , Clitherow Harry
Published: December 2021

Background

The choice of patient-reported outcome measure (PROM) used in shoulder studies varies based on clinician's preference and location. This creates difficulties when attempting to compare studies which have used different PROMs as their outcome measure. This study aims to assess the agreement between the American Shoulder and Elbow Surgeons score (ASES) and the Oxford Shoulder Score (OSS), and identify factors associated with agreement.

Methods

Patients with shoulder pathology were identified from a multi-cohort observational practice registry. 1050 paired ASES and OSS pre-treatment scores were prospectively collected. Linear regression was performed to assess the agreement between the PROMs. Mixed-effects analysis of variance was performed to assess the influence of factors associated with agreement.

Results

Regression for mean total and mean function ASES and OSS demonstrated good fit (adjusted R2 57.7%, P < 0.001; and 63.9%, P < 0.001). Mean pain subscore demonstrated a poorer fit (adjusted R2 39.4%, P < 0.001). Crosswalks to convert between mean scores were produced with reasonable precision. Veterans RAND 12-Item Health Survey score, age and diagnosis cohort influenced agreement.

Conclusion

Mean total and mean function ASES and OSS scores agree well with each other. This allows for a more informed comparison of studies using either PROMs as their outcome measure.
Identification of root causes of clinical coding problems in Iranian hospitals
Authors: Jebraeily Mohamad , Farzi Jebraeil , Fozoonkhah Shahla , Sheikhtaheri Abbas
Published: December 2021

Background

Improving the quality of coded data requires the identification and evaluation of the root causes of clinical coding problems to inform appropriate solutions.

Objective

The objective of this study was to identify the root causes of clinical coding problems.

Method

Twenty-one clinical coders from three cities in Iran were interviewed. The five formal categories in Ishikawa's cause-and-effect diagram were applied as pre-determined themes for the data analysis.

Results

The study indicated 16 root causes of clinical coding problems in the five main themes: (i) policies, protocols, and processes (lack of clinical documentation guidelines; lack of audit of clinical coding and feedback to clinical coders; the long interval between documentation and clinical coding; and not using coded data for reimbursement; (ii) individual factors (shortage of clinical coders; low-skilled clinical coders; clinical coders' insufficient communication with physicians; and the lack of continuing education; (iii) equipment and materials (incomplete medical records; lack of access to electronic medical records and electronic coding support tools; (iv) working environment (lack of an appropriate, dynamic, and motivational workspace; and (v) management factors (mangers' inattention to the importance of coding and clinical documentation; and to providing the required staff support.

Conclusion

The study identified 16 root causes of clinical coding problems that stand in the way of clinical coding quality improvement.

Implications

The quality of clinical coding could be improved by hospital managers and health policymakers taking these problems into account to develop strategies and implement solutions that target the root causes of clinical coding problems.

Introduction:

Violence with physical assault is a common cause of morbidity and mortality prevalent but not limited to underdeveloped countries. The opinion of the forensic expert is often indispensable in such cases to determine the penalties. This study was planned to describe the pattern of presentation of the victims and evaluate the strengths and limitations in formulating a scientific medicolegal opinion based on the findings of the victim.

Methods:

A retrospective descriptive study based on the case records of the victims of assault admitted to Colombo North Teaching Hospital, Ragama, Sri Lanka, was conducted for four years.

Results:

Out of the 400 victims, the majority (72% n = 290) were males and of the age-group of 21 to 40 (n = 216). The reason for assault in the majority was sudden provocation (n = 99, 25%), followed by previous long-duration enmity (n = 89, 22%). The majority (83%) had isolated blunt force trauma, and the injuries were nongrievous (74%). Defense injuries were significantly associated with attempted defense (p = 0.000) and sharp force trauma (p = 0.002). The underlying reason for the assault was not significantly associated with the causative weapon (p = 0.228) or body region injured (p = 0.195).

Conclusions:

Even though the presentation and the pattern of injures are definitely of value in formulating a scientific opinion, the study identified the limitations of the forensic experts, and the need for a holistic approach at the investigations was highlighted.

Over the last several years multiple studies, primarily from European centers have demonstrated the clinical and outcomes benefits of multidisciplinary endocarditis teams. Despite this literature, adoption of this approach to patient care has been slower in the United States. While there is literature outlining the optimal composition of an endocarditis team, there is little information to guide providers as they attempt to transform practice from a fragmented, disjointed process to an efficient, collaborative care model. In this review, the authors will outline the steps they took to create and implement a successful multidisciplinary endocarditis team at the University of Michigan. In conjunction with existing data, this piece can be used as a resource for clinicians seeking to improve the care of patients with endocarditis at their institutions.

Objectives

Vaccination rollout against COVID-19 has started in developed countries in early December 2020. Mass immunization for poor or low-income countries is quite challenging before 2023. Being a lower–middle-income country, Bangladesh has begun a nationwide COVID-19 vaccination drive in early February 2021. Here, we aimed to assess the opinions, experiences, and adverse events of the COVID-19 vaccination in Bangladesh.

Methods

We conducted this online cross-sectional study from 10 February 2021, to 10 March 2021, in Bangladesh. A self-reported semi-structured survey questionnaire was used using Google forms. We recorded demographics, disease history, medication records, opinions and experiences of vaccination, and associated adverse events symptoms.

Results

We observed leading comorbid diseases were hypertension (25.9%), diabetes (21.1%), heart diseases (9.3%), and asthma (8.7%). The most frequently reported adverse events were injection site pain (34.3%), fever (32.6%), headache (20.2%), fatigue (16.6%), and cold feeling (15.4%). The chances of having adverse events were significantly higher in males than females ( p = 0.039). However, 36.4% of respondents reported no adverse events. Adverse events usually appeared after 12 h and went way within 48 h of vaccination. Besides, 85.5% were happy with the overall vaccination management, while 88.0% of the respondents recommended the COVID-19 vaccine for others for early immunization.

Conclusion

According to the present findings, reported adverse events after the doses of Covishield in Bangladesh were non-serious and temporary. In Bangladesh, the early vaccination against COVID-19 was possible due to its prudent vaccine deal, previous mass vaccination experience, and vaccine diplomacy.
Toward Sustainable Development: Assessing the Effects of Commercial Policies on Consumption and Production-Based Carbon Emissions in Developing Economies
Authors: Weimin Zhu , Zubair Chishti Muhammad
Published: December 2021

Over the last few decades, the available literature on environmental economics hosts numerous environmental issues and underlines their reasons, calling for instant action on carbon dioxide emissions (CO2e). In the same context, the recent article develops a new framework that extends the pertinent literature by linking commercial policies, globalization, labor force, GDP growth, fossil fuel, and renewable energy consumption with consumption and production-based CO2e (CCO2e and PCO2e). To this end, the sample of developing economies is utilized from 1991 to 2016. Further, several advanced techniques are applied for robust findings. The findings reveal that the expansionary and contractionary commercial policies significantly affect CCO2e and PCO2e. Likewise, import taxes also have a significant association with CCO2e and PCO2e. Additionally, the results determine that globalization, labor force, GDP growth, fossil fuel, and renewable energy consumption are the essential drivers of environmental pollution. Besides, the panel causality test establishes a one-way causality which runs from commercial policies, import taxes, globalization, labor force, GDP growth, fossil fuel, and renewable energy consumption to CCO2e and PCO2e. Based on the findings, some relevant implications are also suggested.
Controversy and Discourse: The Arts of Transforming Negativity Through Transitivity
Authors: Alharbi Ahlam
Published: December 2021

Controversial topics make discourse complicated and hard to construct. However, through selected linguistic tools, the negativity of controversies can be subdued and reconstructed successfully. In this study, Halliday’s Transitivity System and van Leeuwen’s role allocation were utilized to show how speakers construct social actors in such a discourse to experientially reconstruct controversial topics without evoking negative feelings or creating conflicts. This study examined Jared Kushner’s interview on the peace deal to show how such a controversial topic was constructed. It was noted that Kushner utilized three tools. He (1) foregrounded noncontroversial participants and backgrounded controversial ones, (2) identified actions of noncontroversial participants and suppressed the actions of those who are controversial, and (3) activated positive aspects and passivated negative aspects. In doing so, Kushner evaded controversial arguments by selectively representing participants and their social roles to achieve strategic goals, for example, obtaining a positive response, subduing negativity, and eventually may succeed in encouraging his audience to listen or consider his view.

Numerous studies recently have explored how personality traits, risk attitudes and gender interact, with ambiguous results for different environmental and cultural contexts. To contribute to the existing literature, this study tests the relationship of individual risk attitudes with personality traits, and other variables, in the Czech Republic using the validated Czech version of the Big Five Inventory instrument. The results of an ordinal logistic regression show that risk aversion relates positively to neuroticism and negatively to extraversion and openness to experience. Furthermore, compared with women, men tend to be less risk averse. This study contributes to a better understanding of the influence of personality traits and demographic factors on risk attitude in the context of a culture with high uncertainty avoidance.
