Responding to the call of the NHS Nightingale, but at what cost? An auto-ethnography of a volunteer frontline mental health trainer’s experiences during the COVID-19 pandemic
Authors: Kitto Chloe , Lamb Danielle , Billings Jo
Published: December 2023

Healthcare workers, globally, volunteered time and skills to the COVID-19 pandemic frontline response. In March 2020, the predicted high demand for extra critical care beds led to the rapid construction of the UK National Health Service (NHS) Nightingale field hospital, London. I volunteered to develop and deliver psychological preparedness training – coined ‘Psychological PPE’ – to over 2300 frontline staff over an 8-week period. Existing research has identified broad themes of the impact working on the COVID-19 frontline has on healthcare workers but does not capture in-depth accounts of individuals’ experiences. Using autoethnographic enquiry, this research explores my frontline experience at the NHS Nightingale during this time, and the personal impact this had on me. Reflexive thematic analysis explored themes of recognition and sacrifice, emotional lability and fragility, and the impact of transitions. Findings inform personal recovery, as well as future research and policy development pertaining to the sustainable recovery of our NHS people.
Cross-resistance to entry inhibitors and lenacapavir resistance through Week 52 in study CAPELLA
Authors: Margot Nicolas , Pennetzdorfer Nina , Naik Vidula , Rhee Martin , Callebaut Christian
Published: December 2023

Background

Lenacapavir (LEN) is a first-in-class inhibitor of human immunodeficiency virus type 1 (HIV-1) capsid function for the treatment of heavily treatment-experienced people with HIV (PWH) harbouring multidrug resistance in combination with an optimized background regimen (OBR). Here, we describe in vitro analysis of the interplay between entry inhibitors (EI; enfuvirtide, fostemsavir, ibalizumab, and maraviroc) susceptibility and LEN susceptibility in samples from 72 participants in the phase 2/3 CAPELLA study, as well as the emergence of resistance in CAPELLA through 52 weeks.

Methods

The phenotypic susceptibility to EIs of screening samples from participants was analysed using entry assays, and susceptibility to LEN was generated. Genotypic and phenotypic resistance to LEN was evaluated for subjects with virological failure through Week 52.

Results

Overall, viruses with resistance to EIs showed no cross-resistance to LEN, with a mean fold change from wild type close to 1.0. Of the 22 participants analysed for resistance through Week 52, 9 participants (13%) had emergence of capsid resistance mutation(s) while the remaining 13 participants (18%) had no change in the capsid sequence.

Conclusion

The gag sequence from EI-resistant isolates did not affect LEN susceptibility. The lack of cross-resistance to LEN across ARV-resistant isolates supports the use of LEN in PWH regardless of their treatment history. During the second half-year period of the CAPELLA Study, development of LEN resistance was rare and was overall associated with functional LEN monotherapy due to either nonadherence or resistance-driven non-susceptibility to OBR.
Research on railway vehicle modal parameter identification method based on drop impact load
Authors: He Xiaolong , Duan Zhengyong , Wu Yangjun , Tang Dayong , Peng Shuai , Tang Bangbei
Published: December 2023

This paper investigates the modal parameter identification technique utilizing a drop impact load. A 12-DOF mathematical model of a Railway Vehicle System (RWVS) was constructed, followed by theoretical calculations, simulation analysis, and tests with four different drop impact loads. The responses to these loads were inspected through FFT, and the modal frequencies of the RWVS were determined by the Peak Picking (P-P) method. The simulation demonstrated that four types of drop impact loads can activate the bounce, pitch, and roll modes of the RWVS. The theoretical calculation and simulation analysis revealed that the maximum error of modal frequency identification is no greater than 6.5%. The experimental results verified that the drop impact excitation method can be used to identify the modal parameters of a complex railway vehicle system, which is highly beneficial for the design and verification of the vehicle structure.
Short remarks on the paper: A novel methodology for a time-delayed controller to prevent nonlinear system oscillations
Authors: El-Dib Yusry O
Published: December 2023

In this brief communication, we highlight several critical inaccuracies in the paper entitled “A novel methodology for a time-delayed controller to prevent nonlinear system oscillations,” identified by the DOI: 10.1177/14613484231195276. The core of the non-perturbative approach discussed in this paper is the introduction of a trial solution with an indeterminate nonlinear frequency. We elucidate the technical missteps and provide necessary corrections. The scrutinized article presents ample opportunities for enhancement, and we propose several amendments. Additionally, we reveal that the numerical outcomes showcased in the mentioned paper expose deficiencies in the proposed approximate solution. With the amendments implemented herein, a more precise numerical solution is achieved.
Young children's narratives of exclusion in peer relationships in early childhood education and care
Authors: Sevón Eija , Notko Marianne , Salonen Eija , Lahtinen Maria
Published: December 2023

In peer culture, children develop social and moral orderings that justify exclusion of one or more peers – an area that has sparked debate among early childhood education groups. Therefore, the present study employed the idea of the power order or social and moral ordering of belonging to explore young children's narratives of social exclusion. We asked what story types can be identified in these narratives and how exclusion is reasoned in them. The data consisted of 25 narratives produced by 12 children, aged 4–6 years, via the Story Magician's Playtime method in early childhood education and care in Finland. Four story types were identified (repulsion, hierarchy, adult as mediator and conciliation), in which the moral reasoning for and conclusion of the exclusion differed. The diverse story types manifested complex negotiations, meaning-makings and diversity of emotions, in which children transcended dichotomous, black-and-white moral reasoning. Children's narratives illuminate how they negotiate social orders in situational interactions. Rules prescribed for children from adults are reproduced, modified and reinterpreted in these interactions. The narratives imparted the contradictions between preserving specific rules and members for ongoing play and the altruistic all-can-participate rule. The study highlighted the importance of addressing exclusion situations in ECEC. If social exclusion is not reflected on with children, they are left alone to solve these situations, which may cause a vicious cycle for repeatedly excluded children.
Spinal Cord Protection During Thoracic and Thoracoabdominal Endovascular Aortic Repair: 5-Year Results of a Preventive Protocol Including Prophylactic Cerebrospinal Fluid Drainage in High-Risk Patients
Authors: Borghese Ottavia , Brisard Laurent , Le Corvec Tom , Hauguel Alexandra , Guimbretière Guillaume , Maurel Blandine
Published: December 2023

Purpose:

Spinal cord injury (SCI) is a devastating complication of thoracoabdominal aortic (TAA) repair. The use of prophylactic cerebrospinal fluid drainage (CSFD) as part of a protective protocol during endovascular repair is controversial. This article reports the results of the prophylactic use of CSFD as part of the of a prevention protocol implemented in 2016.

Methods:

Retrospective review of spinal cord outcomes (SCI rate and CSFD-related complications) in patients treated endovascularly for TAA disease at a single institution from 2016 (implementation of an institutional SCI risk reduction protocol) to 2021. Patients were classified as high risk (≥2 factors), intermediate risk (1 factor), or low risk (0 factor). Only high-risk patients without contraindications underwent a prophylactic CSFD placement.

Results:

One hundred eighty-one patients were analyzed (124 males; 69.6 years): 130 (69%) aneurysms (n=24 thoracic, n=28 Crawford 1–2–3, and n=78 Crawford 4/pararenal), 35 (19.9%) chronic aneurysmal dissections, and 16 (8.8%) acute complicated type B dissections. Interventions were staged in 31 (17.2%) cases, and consisted of 74 (41%) Thoracic EndoVascular Aneurysm Repair (TEVAR) and 107 (59%) Fenestrated Branched EndoVascular Aneurysm Repair (F-BEVAR). Sixty-nine (38.1%) patients were identified as being at high risk of SCI and CSFD was used prophylactically in 64 of them (4 failures and 1 contraindication). Spinal cord injury occurred in 8 cases (4 paraparesis, 4 paraplegias including 2 permanent), of which 3 had a prophylactic CSFD and 5 underwent rescue drainage. In addition, 4 patients developed SCI related to prophylactic CSFD (intradural hematoma), resulting in 1 paraparesis and 3 paraplegias. Other CSFD-related complications were mild (6) or moderate (2), for a total of 12 complications (17%). Factors associated with major drain complications were: curative anticoagulation 36 hours after drain removal (n=1), multiple punctures (n=1), platelet count <100 000 at drain removal (n=1), and bipolar disorder (n=2). Overall, 4 patients had permanent paraplegia and 1 had sphincter dysfunction at the last follow-up. Mean follow-up was 17 months. Mortality was 4.4% at 30 days and 13.3% at 18 months, including 3 (1.6%) aortic-related deaths.

Conclusions:

With the protocol we used to protect the spinal cord, we report results comparable with the SCI literature and highlight the risks associated with prophylactic CSFD use, which requires a better understanding of contraindications.
An Intersectional Exploration of Psychological Violence, Threats, and Physical Violence of Mayors in 2021
Authors: Herrick Rebekah , Thomas Sue
Published: December 2023

Using an original dataset, we offer an intersectional exploration of psychological violence, threats, and physical violence against U.S. mayors in 2021 in cities of 10,000+ in population. We also explore violence that is gendered and raced. Overall, we find significant and meaningful differences among gender/race groups. Women of color and non-Hispanic white women faced higher rates of threats, gendered, and sexualized violence than men, and women of color were the only mayors to report heightened levels of gendered and raced violence. Non-Hispanic white women mayors were distinctive in that they reported higher levels of psychological violence, including being criticized for their appearance and perceptions that they were too emotional, but were least likely to be called sexist. These findings suggest that there are race- and gender-based costs of holding office. If so, the effects on democratic representation and the benefits from representational diversity will be forfeited.

Published: December 2023

Background

Functional non-retentive fecal incontinence (FNRFI) is a psychologically upsetting and embarrassing issue and affects children's quality of life negatively.

Aim of this study

Evaluation of the short and long-term effect of Bilateral transcutaneous posterior tibial nerve stimulation (BTPTNS) in the treatment of FNRFI in children and its impact on the quality of life (QoL). Methodology: The current randomized controlled study included 94 Children with FNRFI who were randomly allocated into two equal groups. Group A received BTPTNS and Group B Received Sham BTPTNS. Follow-up was planned for 24 months for manometric findings, incontinence score, Incontinence episodes, and the QoL.

Results

The incontinence score was significantly decreases in Group A more than what was reported in Group B at 6, 12, 24 months follow up . In group A 53.2% of the included children who received BTPTNS showed a decrease in the incontinence episodes more than 75% and among them, 23.4% were fully continent. All the QoL domains were significantly improved in Group A after 6, 12, and 24 months when compared with Group B.

Conclusion

BTPTNS can be a good modality in the treatment of FNRFI with favorable long-term maintenance of its effect together with a remarkable positive impact on all domains of QoL.
Initial Development and Validation of the Campus Recreation Constraints and Negotiations Questionnaire
Authors: Newsome A'Naja M. , Garcia Jeanette M. , Dedrick Robert F.
Published: December 2023

Despite the known benefits of campus recreation participation, many students do not engage with the programs and services offered on college campuses. College students report factors that constrain leisure time physical activity within the context of campus recreation. Examining the constraints and negotiation strategies of college students specific to the use of campus recreation facilities and programs is understudied and lacks validated instruments. The purpose of this study was to develop and report initial validity and reliability of the Campus Recreation Constraints and Negotiation Questionnaire. Exploratory factor analysis and confirmatory factor analysis were used to evaluate two independent scales. Psychometric properties including construct validity, internal structure, and reliability are reported from two different samples of college students. Practical implications for campus recreation programming and marketing efforts are discussed.

Authors: Zuest Luciana , Lee Saemi , Fogaça Janaina , Squires Nikole , Clifford Dawn E.
Published: December 2023

Exercise professionals often hold anti-fat attitudes, which contribute to weight stigma and discrimination in physical activity contexts. This study examined the effects of an online weight stigma intervention on exercise professionals’ attitudes toward fatness. Participants were 105 exercise professionals who were employed at least part-time at university recreation centers in the United States. In this randomized controlled trial, participants were randomized into an intervention online course to decrease weight stigma or a control online course to learn about communication techniques to enhance motivation for physical activity. Attitudes about fatness were assessed at pre- and post-course using the Fat Attitudes Assessment Toolkit (FAAT). There were significant increases in the fat acceptance composite score in the intervention group compared to the control group, suggesting recreation center staff who completed the intervention WIT FITS course experienced more positive evaluations of fat people as a result of the intervention.

Authors: Askari Sussan , Phadke Chetan P. , Fernandez Juan Antonio , Frates Elizabeth P.
Published: December 2023

Background: Stroke is the leading cause of disability and the second-most leading cause of mortality. Stroke has both physical and psychological impact on the lives of stroke survivors. Lifestyle modifications have a pivotal role in post-stroke management care. The Paving the Path to Wellness Program (PPWP) is a 12-week program offered to stroke survivors at Spaulding Rehabilitation Center following discharge. The program encompasses the following domains: physical activity, nutrition, stress management, time-outs, energy, sleep, purpose, and social connections. Objective: The purpose of this pilot study was to evaluate the effectiveness of the PPWP on the recovery of stroke survivors. Methods: Three stroke survivors who participated in the program were interviewed following completion of the program. Results: The results showed the PPWP had a positive impact on physical health (e.g., increased physical activity, weight loss, nutrition awareness, and better stress management); helped to create a new purpose (e.g., happiness, satisfaction, and well-being); and improved the social life of the participants (better awareness and importance of friends and family). Conclusions: Next steps are to study this program in a larger stroke population and examine long-term effects.
Evaluating the Extent of Participation of People Living With Dementia in Research
Authors: Niner Sara , Bran Felicitas , Mohan Devi , Warren Narelle
Published: December 2023

Most research about dementia consults with carers, community workers, nurses or other health professionals, but rarely with people living with dementia (PLWD). This paper investigates why this is the case and documents the extent to which dementia research includes those with lived experience. We searched for studies reported in academic articles focussing on dementia that described using participatory methods. Approximately half of the studies we found were excluded because the purpose of the research was commercial (developing apps or other products) and comprised only superficial product testing with PLWD rather than seeking any insight into their lived experience. Other studies were excluded because for various reasons, most significantly not meeting the definition of participatory methodology we adopted from Cornwall and Jewkes (1995). Ultimately only 27 academic articles were included in the analysis. In each of these studies the seven stages of research we identified (conception; design; participant recruitment; data collection; analysis; validation and knowledge translation) were evaluated for participatory methods. We found only one study which undertook participatory methodology in all stages which was the intended purpose of the research. We found that recruiting research participants, undertaking data analysis or validation with PLWD was seldom done and conceiving the study with PLWD was the rarest of all. In most studies we identified that participatory research was limited to only two or three research phases: data collection scored highest, then dissemination of data and then design. We found that participatory research with PLWD was not often considered possible and that rationales for the lack of consultation, when given, were largely ethical, or because of resource and time constraints. We found however that certain environments and approaches were more hospitable to PLWD involvement. This article describes exemplary examples of participatory research in different stages of the research processes, documents the strategies used to enhance participation and recommends increasing participatory methodology so as to better understand the perspectives and insights of PLWD making assessments and recommendations more effective.
The portrayal of non-western sports hosts in International Media: A comparative analysis of BBC, Al Jazeera English, and RT's coverage of the 2022 FIFA World Cup
Authors: Abdul Rehman Fatima , Jebril Nael
Published: December 2023

This study analyses news coverage of Qatar's hosting of the 2022 World Cup by three global news websites – Al Jazeera English (AJE), BBC World News, and RT English – over a period of nine years leading up to the tournament. Except for AJE, which focused on infrastructure development and political issues, the media outlets prioritised critical concerns by highlighting the social problems faced by migrant workers, while local community issues were given less attention. Although migrant workers received substantial media coverage, they were the least cited on all three news websites. Official sources were preferred to unofficial and public sources, and international sources were cited more often than Qatari sources. The most commonly used frame was conflict, whereas the human interest frame was the least utilised. These findings are discussed in light of the debate on the international coverage of hosting mega sport events in non-Western societies.

Published: December 2023

Background:

Validated predictors of sensitivity or resistance to Bevacizumab (Bev) are not available, and Inflammatory Indexes (IIs) has been reported to be useful prognostic factors in various malignant solid tumours, including metastatic colorectal cancer (mCRC).

Objectives:

To explore the prognostic value of IIs in mCRC patients treated with first-line chemotherapy plus Bev.

Design:

One hundred and eighty-two patients diagnosed with mCRC and treated with first line chemotherapy plus Bev were considered for this prospective non-pharmacological study. Neutrophil, lymphocyte, platelet, aspartate transaminase (AST) and lactate dehydrogenase (LDH) tests were carried out at baseline and before each treatment cycle, according to clinical practice.

Methods:

Pre-treatment Systemic Immune-inflammation Index (SII), Colon Inflammatory Index (CII) and Aspartate aminotransferase-Lymphocyte Ratio Index (ALRI) were evaluated to assess a correlation with progression-free survival (PFS) and overall survival (OS).

Results:

In the overall population, PFS and OS were lower in patients with high SII (HR 1.64, p = 0.006 and HR 1.75, p = 0.004, respectively) and high ALRI (HR 2.13, p = 0.001 and HR 1.76, p = 0.02, respectively), but no difference was detected according to CII value. The multivariate analysis confirmed both SII and ALRI as independent prognostic factors for PFS (HR 1.64 and 2.82, respectively) and OS (HR 1.65 and 2.12, respectively).

Conclusion:

Our results demonstrate and confirm that IIs, and in particular SII and ALRI, are easy to measure prognostic markers for patient candidates to first line chemotherapy plus Bev for mCRC.
Dissemination of Reactivated Coccidioidomycosis Inducing Diffuse Alveolar Damage: A Rare Autopsy Case Report
Authors: Onur Pelin , Fidan-Ozbilgin Ozlem
Published: December 2023

Coccidioidomycosis is a fungal infection prevalent in the Southwestern United States and Northern Mexico. Given its rarity and often asymptomatic nature, disseminated coccidioidomycosis frequently omitted in preliminary differential diagnoses. Our case study presents the postmortem results of an individual who had a reactivated coccidioidomycosis, causing diffuse alveolar damage and resulting in his death. This case study underscores the importance of considering coccidioidomycosis in initial differential diagnoses, particularly in patients with prior exposure to the infection and associated risk factors.
An Analysis in Identifying the Mechanism of Action of the Alkaloids Found in Berberis vulgaris on the Treatment and Prevention of SARS-CoV-2
Authors: Gildenhuys Samantha , Steenkamp Paul Anton , Sekele Lucas , Mosebi Salerwe , James Chad Clifton
Published: December 2023

Introduction

Berberis vulgaris extract is a well-known herbal remedy for treating numerous conditions including coronavirus disease 2019 (COVID-19). The HAB4a method of preparing the extract is a common method used in clinical practice and a further aim of this study was to identify the key alkaloid compounds that are present in an alcohol versus a glycerine-based extraction and determine the mechanism by which these prevent and treat COVID-19.

Results and Discussion

Identified alkaloid compounds included bervulcine, vulracine, berberrubine, lambertine, berbidine, obamegine, berbamine, berberine, and palmatine in the alcohol-based extract. The glycerine-based extract contained all except bervulcine, vulracine, and berbidine. Berberine and palmatine were the most abundant compounds in both extracts but more berberine was present in the alcohol-based extract and more palmatine in the glycerine-based extraction. Databases revealed compound-gene interactions with human targets involved in signalling and gene regulation networks that could synergistically change cell function. The SARS-CoV-2 spike 1 protein purification yielded about 5 mg of highly purified protein (˃95%) from 1 L of bacterial culture. Isothermal titration calorimetry (ITC) analysis of any potential interaction of palmatine and berberine with the purified spike 1 protein was negative. Thus, it is possible the extract components work in a synergistic manner to prevent and treat COVID-19.

Conclusions

Berberis vulgaris root extract alkaloid components differ when alcohol or glycerine is used. Berberine and palmatine are the most abundant alkaloids but differ in the amount relative to each other in the extracts. The extract components could affect changes in a variety of human genes.

Materials and Methods

Ultra-High-Performance Liquid Chromatography—High-Definition quadrupole time-of-flight Mass Spectrometry was used to identify alkaloids. Databases were used to determine the genes that interact with the identified compounds. SARS-CoV-2 spike protein was expressed and purified. Purified protein was used in ITC with berberine and palmatine.

Objectives: Carallia brachiata Merr. is a Vietnamese medicinal plant, used to treat mouth ulcers, tongue sores, sore throats, and malaria. This paper focuses on the chemical constituents of C. brachiata and their inhibition of NO production. Methods: The dried and minced sample was extracted with methanol. The crude extract was isolated by various chromatographic methods. The structures of the isolates were determined by HR-ESI-MS, NMR, and CD spectra. The NO inhibition activity was evaluated in LPS-activated RAW264.7 cells. Results: Two new catechin derivatives (carabrachiatanins A (1) and B (2)) and seven known proanthocyanidins (3-9) were isolated from C. brachiata by bioguided fractionation. All isolates significantly showed NO inhibition effects with IC50 values ranging from 13.72 ∼ 34.28 µM. Conclusions: Two new and seven known compounds were isolated from C. brachiata. This is the first report of compounds 3-9 from C. brachiata. Compounds 7 and 8 inhibited NO production with their IC50 values of 16.31 ± 0.61 µM and 16.53 ± 0.83 µM, respectively, compared to that of dexamethasone, which showed IC50 value of 14.94 ± 1.11 µM.
Nationally Representative Trends in Incidence of Procedures Done Concomitantly With Primary and Revision Total Ankle From 2012 to 2020
Authors: Anastasio Albert T. , Walley Kempland C. , Kim Billy I. , Bethell Mikhail A. , Adams Samuel B.
Published: December 2023

Background

As new literature emerges and practice patterns fluctuate, there is a significant potential for variation with regard to adjunctive procedures performed with primary total ankle arthroplasty (pTAA) and revision total ankle arthroplasty (rTAA). Our study aims to evaluate yearly trends in the incidence of concomitant procedures and compare the incidence of adjunctive procedures between pTAA and rTAA.

Methods

The 2012-2020 American College of Surgeons National Surgical Quality Improvement Program (ACS-NSQIP) database was queried for all pTAA and rTAA. The number of concurrent procedures was compared between pTAA and rTAA and compared across years available in the most current version of the NSQIP database (2012-2020).

Results

Patients undergoing pTAA had a higher mean age than patients undergoing rTAA (64 vs 61 years; P < .001), and patients undergoing rTAA had higher wound class (P < .001), indicating higher levels of contamination. Concurrent procedures were performed significantly less frequently with pTAA than rTAA (mean procedures 0.82 vs 1.30; P < .001). Removal of deep implants was more commonly coded with rTAA than pTAA (9.0% vs 17.7%; P < .001). Gastrocnemius recession was more frequently performed with pTAA than rTAA (10.4% vs 3.0%; P = .001).

Conclusion

As pTAA and rTAA increase in incidence throughout the United States, there is increased importance on furthering our understanding of these procedures. This study provides a nationally representative analysis of adjunctive procedures with pTAA and rTAA from 2012 to 2020. Generally, more adjunctive procedures are performed with rTAA versus pTAA, confirming the high complexity of rTAA.

High-velocity impact experiments and quantitative damage evaluation for finite ultra-high-performance concrete targets
Authors: Sauer Christoph , Burtsche Jan , Heine Andreas , Roller Christoph , Riedel Werner
Published: December 2023

In this work, we aim at improved characterization of target damage occurring as the result of projectile impact against ultra-high-performance concrete (UHPC). For this purpose, we present the results of high-velocity impact experiments with spherical steel projectiles and finite-thickness UHPC targets of approximately 115 MPa compressive cylinder strength in the impact velocity range from approximately 600 m/s to 1500 m/s. The data set obtained from these experiments includes residual projectile velocities as well as qualitative and quantitative information on damage. Quantitative damage information is mainly extracted from digital 3D post mortem targets, which are produced by 3D-scanning. For all damage quantities, a dependence on the impact velocity and the target thickness is discussed and used to provide possible explanations for the origin of the particular type of damage. The large data set presented in this work can constitute the basis for a comprehensive and quantitative verification and validation of analytical, empirical, and numerical models that describe the perforation of UHPC targets in the investigated impact velocity range.
Promoting dietary self-efficacy through social support: An application to online weight-loss communities
Authors: Gallin Steffie , Balbo Laurie , Lichtlé Marie-Christine
Published: December 2023

An increase in the number of individuals trying to lose weight has enabled the development of online weight-loss support communities (Weight Watchers, Dukan, etc.). This research aims to study whether and how social support in these communities affects dietary self-efficacy to improve individuals’ food well-being. After an initial qualitative study with 25 community users, we formulated hypotheses and tested them in a quantitative study involving 335 users. The results show that social support contributes to dietary self-efficacy through two sequential mediators: identification with community members and motivation to comply with group norms. Our analyses also show that nutritional knowledge moderates the relationship between motivation to comply and dietary self-efficacy. The results of these two studies enrich the literature on online communities and allow us to suggest managerial recommendations for administrators of these communities and health professionals.
Clearness qualitative comparative analysis of the spread of TikTok health science knowledge popularization accounts
Authors: Tian Yu , Liu Shuaishuai , Zhang Desheng
Published: December 2023

Objective

This study analyzed the popularity of TikTok health knowledge popularization accounts with the objective of creating a template for accounts suited to widely disseminating information, thereby enhancing the public's access to health knowledge on a broader scale.

Methods

This study is based on 40 Chinese TikTok short video accounts that were active from February to April 2022 and were engaged in health science popularization. Data were validated by structured calibration using three qualitative anchors. It employs the “content–context” and the elaboration likelihood models as the theoretical framework. A qualitative comparative analysis is used to explore the factors affecting the popularity of this type of account mechanism.

Results

Among the nine variables involved in the calculation, one reached 0.909091, demonstrating that the number of followers was both a necessary factor and a condition for the popularity of short health science video accounts. There were 16 paths in the complex solution with a consistency of 1, and their overall coverage reached 0.878788, indicating that approximately 87% of the cases could be explained. From the spread of the content and communication situation, professional medical knowledge, current hot topics, professionals, and serious issues were the most likely combinations for rapid spread. From the perspective of the central and edge paths, “likes” exceeding 100,000 and fans exceeding 1 million were essential combinations.

Conclusions

The dissemination of medical knowledge has gained significant traction, especially with regard to trending and popular topics. When it comes to the tone of communication, a serious style proved effective in fostering what can be termed “hot communication.” From the standpoint of central and peripheral paths, it is crucial that the number of likes in the past month and the total number of fans surpass 100,000 and one million, respectively.
The preliminary efficacy of virtual agent-assisted intelligent rehabilitation treatment (Echo app v2.0) in patients with alcohol use disorders: Study protocol for a randomized controlled trial
Authors: Li Shuo , Zhang Dapeng , Liu Jingyang , Su Hang , Guo Lei , Wu Qianying , Du Jiang , Jiang Haifeng , Zhong Na , Huang Chuanning , Chen Tianzhen , Zhao Min
Published: December 2023

Background

Alcohol use disorder (AUD) is one of the most common substance use disorders. People with AUD are in great need of highly accessible and comprehensive management, involving medicine, exercise, and psychotherapy. However, due to limited resources, providing comprehensive treatment for every patient is challenging. Virtual agent-assisted intelligent rehabilitation treatment can improve the accessibility of comprehensive management.

Objectives

This randomized controlled trial aims to test whether the virtual agent-assisted intelligent rehabilitation treatment (Echo-app-v2.0) plus treatment as usual (TAU) has greater efficacy than only TAU in AUD.

Methods

One hundred participants with AUD will be recruited and randomly assigned to either TAU or virtual agent-assisted intelligent rehabilitation treatment plus TAU based on the 1:1 ratio. The virtual agent-assisted intelligent rehabilitation treatment is delivered by the Echo app v2.0 developed by our research team. Participants will be assessed at baseline, week 4 of treatment, one month, and three months after the end of treatment. The primary outcome is the participants’ craving for alcohol, measured by Visual Analogue Scale. Other outcomes include the use of alcohol, motivation for treatment, coping style, depression, anxiety, impulsivity, stress, and sleep quality.

Discussion

The virtual agent, with vivid human image, high privacy, and the ability to interact with users, has the potential to play an important role in the delivery of digital psychotherapy. The development of Echo app v2.0 has the possibility to raise the availability of comprehensive treatment for people with AUD.
Do Bank Funding Diversity and Bank Lending Affect Net Interest Margins? Evidence From Asia Markets Before and During the Covid-19 Pandemic
Authors: Duong Khoa Dang , Le Hoi Vu , Vu Duy Nhat , Le Ai Ngoc Nhan
Published: December 2023

This paper investigates how bank funding diversity and lending affect bank performance, especially during the Covid-19 pandemic. We employ the Generalized Method of Moments to analyze unbalanced panels of commercial banks in China, Taiwan, and Vietnam. The empirical results show that a percentage increase in bank funding diversity and bank lending in the sample negatively affects profitability. In contrast, the results are mixed in each country due to different market microstructures. While holding diversified funding strengthens bank profitability during the pandemic, increasing lending activities dampers the bank’s performance. Finally, this research has important implications for bank managers and regulators to develop sustainable banking performance in emerging markets, especially during pandemics.

With the e-Government, the state-stakeholder relationship has gained a different dimension. This opened the door for public services that are participatory, affordable, transparent, efficient, quick, and flexible. The factors that affect the adoption and utilization of e-Government projects, which are implemented at significant expense, must be identified. Differences in acceptance and use of e-Government projects depend on country factors. Thus, this study aims to determine the factors affecting the acceptance and use of the Northern Cyprus E-Government Project by survey method. The study has a distinctive quality because there hasn’t been a thorough investigation in this area in Northern Cyprus. In addition, the data obtained at the end of the study will contribute to the literature on e-government applications and use in developing countries. The study was based on UTAUT and LISREL and SPSS package programs were used for data analysis. Structural equation models were used to analyze the findings in the study. The findings showed that every component had a positive impact on the participants’ intention to utilize. The major factors were found to be performance expectancy, effort expectancy, and trust in the Internet.
Effects of Materialist Values and Work Centrality on Organizational Citizenship Behaviors
Authors: Uçanok Tan Başak
Published: December 2023

The current study investigates the effects of work centrality and materialistic values on organizational citizenship behaviors (OCBs). The importance of organizational citizenship behaviors has been well documented in the management literature. Although OCBs are hard to define, researchers emphasize that these behaviors are more or less discretionary, less likely to be formally linked with organizational rewards and contribute to the organization by promoting a positive social and psychological climate. Although the accumulation of research on OCBs and related constructs is vast, materialistic values as an antecedent have received scant attention. In the current study, materialistic values and work centrality are investigated as predictors of OCB, which have inverse effects on the construct. In a cross-sectional design, 439 employees from various companies in Turkey participated in an online survey. The findings support the claim that inverse effects from work centrality and materialistic values influenced OCB. Upon deconstructing the antecedents’ impact on the dimensions of OCB, the results revealed a positive predictive effect of work centrality on helping and civic virtue. In contrast, materialistic values exerted a negative influence only on helping behaviors. Implications and future research directions are discussed in line with the findings.

The major challenge of most basic schools is inadequate educational resources despite a conscious effort to constantly provide. This is a result of inaccurate data management leading to inappropriate predictions for effective planning. The actual efficiency of a system is determined by its ability to predict real-life data with speed and accuracy. In this work, the neural educational expert system (ES) is evaluated using mathematical models for predicting the availability of resources for the growing school-aged population using a criteria-based formative evaluation to know resource life and its effect on availability. This will help in the decision to add more resources by knowing when and how the resources should be added. Technical mathematical model generation through differential equations is used to fuse the factors affecting the availability of educational resources. The real-life data is used in prediction regarding the actual enrollment of learners and the availability of resources. The model is evaluated and critically analyzed to know the degree of accuracy and the steady state. The findings revealed that the resources decay and attrite at an exponential rate in the long run and the constant number of resources provided cannot cater for the rate of decay, resulting in inadequacy. A proposed algorithm for managing the resources is presented.

Big data analytics (BDA) enhances knowledge and decision-making. Despite its importance, the connection between technical progress and political change is neglected in the administrative process. Most studies focus on e-government, e-governance, and how technology can improve existing operations of the bureaucracy. However, this article aims to explore the potential of BDA for public policy systems and provide a linkage for the transformation toward digital and smart governance using preferred reported items for systematic review and meta-analysis (PRISMA) approach to reveal the relevant documents and narrative review approach to interpret the application of BDA at each step of the public policy system. In addition, this study identifies several common public policy-related big data sources and techniques that could be used at the various stages of the public policy process. This study argues that BDA has the potential to be used for policy formulation in the four main phases—planning, design, service delivery, and evaluation. Most studies confirm its potential in the policy process for taxation, health, education, transportation, law, economy, and social system. This study reveals that it is also suitable for public policy execution stages, such as public supervision, public regulation, service delivery, and policy feedback. Previous studies have indicated that the application of BDA can transform traditional or manual governance systems into digital and smart governance. We contend that the policy cycle should be seen as a dynamic and iterative process characterized by continuous evolution. Though each step of transformation has its unique challenges in handling BDA and maintaining the Information and Communication Technology (ICT) infrastructure, it can ensure an accurate, prompt, and context-oriented public policy system. These insights provide a novel outlook on effectively managing the interplay between innovation and traditional approaches in the realm of public policy development.
Association Between Living Arrangements and Psychological Well-Being Among Older Adults in Rural China: Activities of Daily Living Disability as a Moderator

This study investigated the association between living arrangements and psychological well-being (PWB) among older adults in rural China and whether activities of daily living (ADL) disability moderate this association. The study data were drawn from the sixth to eighth waves of the Chinese Longitudinal Healthy Longevity Survey. The baseline sample included 4,042 individuals aged 65 years and above. PWB was measured using seven mood-related and personality-related questions. ADL disability was measured using Katz’s 6 items of ADL. Living arrangements were categorized into six categories. Linear mixed-effect models were used to examine the association between older adults’ living arrangements and PWB as well as the moderating effect of ADL disability on this relationship. The results showed that compared with living alone, living with spouse only, and living with spouse and children were positively associated with PWB (β = .621, p < .01; β = .527, p < .05), and living with children (no spouse) was negatively associated with PWB (β = −.564, p < .001). ADL disability was negatively associated with PWB (β = −.457, p < .01). Living with children (no spouse) × ADL disability had a positive interaction effect (β = .278, p < .05). These findings suggest that living alone and living with children (no spouse) are not conducive to PWB among older adults in rural China, and ADL disability reduces the negative effects of living with children (no spouse) on PWB. Our findings provide a crucial direction for PWB interventions aimed at older adults in rural China.

Work-based learning experiences (WBLEs) provide students with opportunities to learn about careers and gain work skills required for post-school employment. WBLEs may be especially important for students with extensive support needs (ESN) who often struggle to access competitive, integrated employment after graduation. The purpose of this study was to understand teachers’ beliefs about the benefits of and barriers to school and community WBLEs for students with ESN. We invited 1,498 U.S. special education teachers with a license in ESN to participate. Eligibility criteria required teachers to have at least one high school student with ESN on their caseload. Of the 273 teachers who responded, 137 met criteria and completed the questionnaire. We used descriptive statistics, exploratory factor analyses, and nonparametric inferential statistics to analyze our data. Teachers believed students benefit from WBLEs because they learn skills and have improved outcomes; however, they rated student outcomes higher for community WBLEs (vs. school WBLEs). Barriers to WBLEs included limited resources, stakeholder support, curriculum, and support for students. Teachers rated barriers related to stakeholder support and support for students higher for community WBLEs (vs. school WBLEs). Teachers’ beliefs about the benefits of and barriers to WBLEs varied by their experience with WBLEs. Implications for future research about students’ experiences during WBLEs and how teachers make decisions about WBLEs are discussed.
Revisiting the Relationship Between Sports Fandom and the Black Criminal Stereotype: A Replication and Extension Study
Authors: Anderson Lauren C. , Raney Arthur A.
Published: December 2023

In news media, one stereotype that is continually over-represented is Black men as criminals, leading to what many refer to as “the Black criminal stereotype.” Although research demonstrates that distorted news portrayals of criminals can provoke stereotypical responses in viewers, limited evidence connects these effects to sport media. Anderson and Raney (2018) explored this in an experimental study ( n = 234) and found evidence of the Black criminal stereotype among sports fans. However, more research was needed to further explore this phenomenon. The current study employed a similar experimental design ( n = 603) in an attempt to (1) replicate their 2018 study to examine whether sports fans’ perceptions of criminal athletes have changed over the past several years, especially in light of the Black Lives Matter movement, and (2) determine whether the sport played by an alleged criminal athlete might be linked to judgments regarding race and crime in sports. Our findings indicate that sports fandom still predicts stereotypical judgments. However, individual difference variables—particularly social conservatism, African American stereotype endorsement, and gender—were more strongly related. Our findings point toward the potential power of social movements in influencing attitudes and beliefs regarding race and crime.
