Animal models are important in preclinical psychopharmacology to study mechanisms and potential treatments for psychiatric disorders. A working group of 14 volunteers, comprising an international team of researchers from academia and industry, convened in 2021 to discuss how to improve the translational relevance and interpretation of findings from animal models that are used in preclinical psychopharmacology. The following paper distils the outcomes of the working group’s discussions into 10 key considerations for the planning and reporting of behavioural studies in animal models relevant to psychiatric disorders. These form the iTRIPP guidelines (Improving Translational Relevance In Preclinical Psychopharmacology). These guidelines reflect the key considerations that the group thinks will likely have substantial impact in terms of improving the translational relevance of behavioural studies in animal models that are used to study psychiatric disorders and their treatment. They are relevant to the research community when drafting and reviewing manuscripts, presentations and grant applications. The iTRIPP guidelines are intended to complement general recommendations for planning and reporting animal studies that have been published elsewhere, by enabling researchers to fully consider the most appropriate animal model for the research purpose and to interpret their findings appropriately. This in turn will increase the clinical benefit of such research and is therefore important not only for the scientific community but also for patients and the lay public.

Authors: Jones Rosalind , Morrish Sussie C. , Heyworth-Thomas Elizabeth M. , Graham Edith
Published: July 2023

This article investigates entrepreneurial marketing (EM) and use of business recovery frameworks within experiential learning cycles (ELC)s to investigate post-Covid learning techniques during the learning process. Three distinct post-graduate learner cohorts took part in the study consisting of part-time MBA entrepreneurs from the United Kingdom, part-time upGrad MBA students from India (managers and marketers in large firms) and full-time MCom (Masters in Commerce) marketing students in New Zealand. This inductive study uses coursework artifacts, student feedback with thematic coding, and analysis from live business projects. Use of the post-disaster business recovery framework led to deeper learning, increased understanding, and generation of insights and new knowledge. Both student learner and entrepreneurial marketer skills and competencies are evidenced as essential for business resilience and growth in post-pandemic environments, while the framework aided co-creation of learning between the student and the focal business. Implications for marketing educators are offered together with future opportunities for education research in the EM education, entrepreneurship education and marketing fields. The study will allow educators to understand the three student typologies, leading to effective and impactful pedagogy in EM education.

Published: July 2023

A man in his late 60s with a history of angina pectoris developed low back pain during cardiac catheterization. During this episode of back pain, ST segment elevations were noted on the electrocardiogram. The patient reported relief of the pain immediately after implantation of two drug-eluting stents, and the ST segments on the electrocardiogram normalized. The probable mechanisms of low back pain during cardiac catheterization in this patient are briefly outlined.
Delayed pathological finding of a small fish bone causing a purulent cyst in the pharynx: a case report
Authors: Shufen Xiao , Juan Zhang , Ling Wang , Fangru Dong
Published: July 2023

We describe the case of a patient who swallowed a small fish bone and felt it lodge in her pharynx, but failed to seek medical attention in a timely manner. One week later, no foreign body was found in the hypopharynx or larynx, but a small purulent cyst was present in the epiglottic vallecula. A computed tomography scan showed a high-density area on the lingual surface of the epiglottis, which was considered to represent an embedded fish bone. A week later, the patient’s discomfort had subsided, and flexible videoendoscopy showed that the purulent cyst in the epiglottic vallecula had disappeared. We surmise that the purulent cyst had ruptured spontaneously and the foreign body had been discharged. This represents an example of how an impacted small foreign body may be spontaneously discharged from the body.
Brucella pleuritis misdiagnosed as tuberculous pleuritis: a case report
Authors: Yang Yong , Liu Ke-Liang , Zhao Rui , Chang Xiao-Yue
Published: July 2023

Pleurisy and pleural effusion caused by Brucella infection are rare. However, clinicians lack an understanding of these possibilities, and the underlying disorder is easy to misdiagnose. We report a 52-year-old male farmer who was admitted to hospital with a fever, chest pain, and shortness of breath. Closed chest drainage was performed by thoracocentesis, and the concentration of adenosine deaminase (ADA) in the pleural fluid was >45 U/L. Mononuclear cells in the pleural fluid accounted for 90% of the cells, and pathology indicated a large number of lymphocytes. The clinical diagnosis was tuberculosis with tuberculous pleurisy. However, subsequent pleural fluid culture results did not support tuberculous pleurisy. The results of pleural fluid culture indicated Brucella, and the results of Brucella tiger red plate agglutination indicated a titer of 1:400 (+++). The final diagnosis was brucellosis with pneumonia and pleurisy. After 12 weeks of oral treatment, the patient underwent follow-up chest radiographs. Radiography indicated complete resolution of the hydrothorax and pneumonia, and the patient reported no discomfort. The short-term curative effect was excellent. Pleurisy associated with brucellosis should be considered a differential for pleurisy in regions where brucellosis is endemic, to minimize the risk of misdiagnosis.
A case of hypocomplementemic urticarial vasculitis syndrome complicated by eosinophilic pneumonia: a case report and review of the literature
Authors: Kaneko Yuki , Hayashi Shujiro , Igawa Ken
Published: July 2023

The primary symptom of urticarial vasculitis (UV), which is a histopathological leukocytoclastic vasculitis disease, is an eruption that resembles urticaria. Other organs may also experience accompanying symptoms. Lung lesions with UV are mostly obstructive pulmonary disease with smoking. However, the coexistence of eosinophilic pneumonia (EP) and complicated UV remains unclear. We report a man in his 70s with chronic obstructive pulmonary disease who attended our department with ring-shaped erythema, marginal edema, and pigmentation. Additionally, a skin histological analysis showed nuclear dust and perivascular neutrophil infiltration, while a blood sample showed a decrease in C3 and C1q concentrations. Administration of prednisone temporarily improved the eruption. However, he developed a cough and a new UV eruption 1 year later. Computed tomography revealed infiltration in the right upper lobe of the lungs, and a blood sample showed a high eosinophil count. He was finally diagnosed with hypocomplementemic urticarial vasculitis syndrome and idiopathic chronic EP. A previous study showed that serum C1q concentrations in patients with EP were lower when this disease was active. Whether a decline in C1q concentrations can cause EP is unclear. However, our case is unique owing to the co-onset of EP with low complement concentrations and recurrence of UV.

A woman in her early 70s presented with a right fifth rib fracture along with left scapular body and glenoid fractures resulting from a traffic accident. She had no history of lung disease. The patient underwent multi-incisional video-guided arthroscopic fracture reduction and screw fixation in the right lateral decubitus position under general anesthesia, and surgery was followed by chest tube insertion. Left-sided pneumothorax was found during routine postoperative radiography despite the absence of relevant symptoms or signs such as hypoxia, chest pain, or respiratory difficulty. We herein report this unusual case with a brief literature review.
Electric Vehicle Adoption Behavior and Vehicle Transaction Decision: Estimating an Integrated Choice Model with Latent Variables on a Retrospective Vehicle Survey
Authors: Nazari Fatemeh , Noruzoliaee Mohamadhossein , Mohammadian Abolfazl (Kouros)
Published: July 2023

Electric vehicles (EVs) promise a sustainable solution to mitigating negative emission externalities of transportation systems caused by fossil-fueled conventional vehicles (CVs). While recent developments in battery technology and charging infrastructure can help evolve the niche market of EVs into the mass market, EVs are yet to be widely adopted by the public. This calls for an in-depth understanding of public adoption behavior of EVs as one dimension of vehicle decision making, which itself may be intertwined with other vehicle decision-making dimensions, especially vehicle transaction. This study presents an integrated choice model with latent variables (ICLV) to investigate households’—as a decision-making unit—decisions on vehicle transaction type (i.e., no transaction, sell, add, and trade) and vehicle fuel type (i.e., CVs and all EV types, including hybrid EV, plug-in hybrid EV, and battery EV) choice. To analyze the ICLV model empirically, one of the first revealed preferences national vehicle survey involving CVs and all EV types was conducted, which retrospectively inquired about 1,691 American households’ dynamics of vehicle decision making and demographic attributes over a 10-year period as well as their attitudes/preferences. The model estimation results highlight that EV adoption and vehicle transaction choice is influenced mainly by (1) the dynamics of household demographic attributes and (2) four latent constructs explaining attentiveness to vehicle attributes, social influence, environmental consciousness, and technology savviness. Notably, EV adoption promotion policies are found to be likely most effective on socially influenced individuals, who tend to consider advertisement and social trend more when making vehicle decisions.

Published: July 2023

Intelligent systems have been extensively used to improve the reliability of transport services as a result of technological advances. Despite the technical and methodological achievements, public transportation companies are still facing excessive challenges in assessing the performance and reliability of the system. This study establishes a data-driven multi-criteria decision-making model for prioritizing bus routes that illustrates both operator and consumer views on bus routes. The multi-criteria fuzzy outranking process is handled by ELECTRE III and Condorcet methods. The developed model utilizes alternative indices of bus travel-time reliability to fully capture the uncertain nature of the input data. The reliability assessment framework is based on automatic vehicle location (AVL) data which works as an effective evaluation system for enhanced service reliability on different routes network-wide. Using this model, bus transport companies can set a benchmark and a reliable ranking system for their bus routes. This hybrid prioritization framework is used for characterizing and enhancing transport network efficiency. The effectiveness of the model is examined by quantifying the reliability of eight bus routes controlled by the Qazvin public transportation system, in Iran. A wide range of AVL data sources is employed within an in-depth statistical analysis based on both user and operator preferences. According to the concordance matrix results, line 18 has been found to be superior to other bus routes, and the possibility of identifying less efficient bus routes has been fulfilled.

Published: July 2023

Background

Epithelial ovarian cancer (EOC) is the leading cause of death associated with gynecologic tumors. EOC is asymptomatic in early stages, so most patients are not diagnosed until late stages, highlighting the need to develop new diagnostic biomarkers. Mediators of the tumoral microenvironment may influence EOC progression and resistance to treatment.

Aim

To analyze immune checkpoints to evaluate them as theranostic biomarkers for EOC.

Patients and methods

Serum levels of 16 immune checkpoints were determined in EOC patients and healthy controls using the MILLIPLEX MAP® Human Immuno-Oncology Checkpoint Protein Magnetic Bead Panel.

Results

Seven receptors: BTLA, CD40, CD80/B7-1, GITRL, LAG-3, TIM-3, TLR-2 are differentially expressed between EOC and healthy controls. Serum levels of immune checkpoints in EOC patients are positively significantly correlated with levels of their ligands, with a higher significant correlation between CD80 and CTLA4 than between CD28 and CD80. Four receptors, CD40, HVEM, PD-1, and PD-L1, are positively associated with the development of resistance to Taxol-platinum-based chemotherapy. All of them have an acceptable area under the curve (>0.7).

Conclusion

This study has yielded a first panel of seven immune checkpoints (BTLA, CD40, CD80/B7-1, GITRL, LAG-3, TIM-3, TLR-2) associated with a higher risk of EOC and a second panel of four immune checkpoints (CD40, HVEM, PD-1, PD-L1) that may help physicians to identify EOC patients who are at high risk of developing resistance to EOC chemotherapy.
Relationship Between Resilience, Community Participation, and Successful Aging Among Older Adults in South Korea: Mediating Role of Community Participation
Authors: Kim Jung-Ran , Park Sangmi , Lee Chang Dae
Published: July 2023

A high level of resilience is positively related to successful aging. However, interventions to increase resilience in older adults are not yet available. This study aimed to examine the mediating role of community participation in the relationship between resilience and successful aging. Data from 284 individuals aged 60 years and above were analyzed in this cross-sectional study. The pathways among resilience, community participation, and successful aging were statistically significant after controlling for sociodemographic characteristics, depression, disability, and chronic disease. The analysis revealed a partial mediating effect of community participation (unstandardized estimate = .01, p < .01), explaining 16.4% of the total effect of resilience on successful aging. Promoting community participation may be beneficial for enhancing successful aging in community-dwelling older adults. Further studies to examine the causal relationship between community participation and successful aging and to develop community services are recommended to use community resources as means to support successful aging.

Published: July 2023

In this study, we examined associations of social isolation and loneliness with cognitive impairment among older adults from a Rust Belt region in Southwest Pennsylvania. We used data from the population-based Monongahela-Youghiogheny Healthy Aging Team (MYHAT) study. We found that (a) 11 items combined into two reliable composites of social isolation and loneliness; (b) unique to this study, providing unpaid help to others was an indicator of reduced social isolation; (c) social isolation and loneliness were positively associated with cognitive impairment; and (d) these associations were appreciably attenuated by general health and physical functional status and depressive symptoms, respectively. We concluded that social isolation and loneliness are differentially associated with older adults’ cognitive health, and that their effects might operate through separate pathways. Approaches to address social isolation and loneliness should consider the community context and its implications for older adults’ cognitive health.

Published: July 2023

Incineration is one of the most widely used treatments in the field of sewage sludge disposal. However, the choice of sewage sludge incineration process is still controversial. In this study, the comparative life cycle assessment of sewage sludge incineration processes, including the mono-incineration, co-incineration in coal-fired power plants and co-incineration in municipal solid waste (MSW) incineration plants, was carried out from the perspective of environment, carbon footprint and economy. The environmental assessment results show that terrestrial ecotoxicity, freshwater ecotoxicity, marine ecotoxicity, human carcinogenic toxicity and human non-carcinogenic toxicity are the most significant environmental impacts. And the environmental performance of co-incineration in coal-fired power plants is the best. Moreover, the environmental impact is most sensitive to the dehydrant, electricity and fly ash chelating agent. Co-incineration in MSW incineration plants has the lowest carbon emissions, with only 70.50% and 82% of the carbon emissions from mono-incineration and co-incineration in coal-fired power plants, respectively. Furthermore, sewage sludge mono-incineration has the highest disposal costs because of the higher depreciation and solid waste disposal costs. The comprehensive evaluation results reveal that the optimization should focus on the selection of dehydrant and fly ash chelating agent, as well as the improvement of the equipment efficiency.

Plastic waste circularity is a priority at a global level. Sustainable development goals (SDGs) set the ways to go, and the circular economy principles underlined the ‘green’ strategies to be employed. However, in practice, there is still much to do, especially in developing countries, where open burning and open dumping still represent the common way of plastic waste disposal. This review aims to analyse current plastic waste circular approaches in low-middle income settings. Seven countries were selected based on the economic level and data availability from the authors, and analysed to collect and critically discuss the actions implemented at a city level. Examples of waste minimization and recycling strategies, selective collection systems and public campaigns are reported from Africa, Asia and Latin America. First, a background analysis related to physical and governance aspects of municipal solid waste management systems of the chosen settings was conducted. The assessment was focused on the treatment processes or minimization actions. Then, the applicability of the projects to achieve the SDGs was commented on. The outcomes of the research underline the need to: (1) scale up small-scale and pilot projects, (2) disseminate good practices in more low- to middle-income settings, (3) create synergies among international partners for further replications in cities. Urgent solutions to plastic waste pollution are needed. The review presented practical actions to be implemented now to boost plastic waste circularity in developing cities.

Hydrogels based on natural polysaccharides have received special attention in the last decade due to their interesting features, such as availability, biocompatibility, biodegradability and safety. Such characteristics may make them sustainable and eco-friendly materials for water and wastewater treatment, meeting the concept of circular economy. In this study, a novel double-cross-linked alginate-based hydrogel has been successfully synthesized using epichlorhydrin and sodium trimetaphosphate (STMP) as cross-linker agents and then used for the removal of methylene blue (MB) dye under different operating conditions. The obtained hydrogel was deeply characterized by using various analytical techniques, namely Fourier transform infrared spectroscopy, X-ray diffraction, scanning electron microscopy and differential scanning calorimetry. Experimental results showed that the synthesized double cross-linked hydrogel with relatively high STMP concentration (0.26 M) has promising structural and textural properties. This material exhibited excellent removal ability towards MB with a maximum adsorption capacity of about 992 mg/g for an initial pH of 10. The kinetic and isotherm modeling study revealed that the pseudo-second-order and Freundlich models fitted well the measured adsorption experimental data. The MB adsorption process onto the synthesized hydrogel is exothermic, feasible and spontaneous. It mainly includes electrostatic interaction and hydrogen bonds. These findings suggest that double-cross-linked alginate-based hydrogel can be considered as an attractive and potential adsorbent for an effective cationic dye removal from aqueous environments. The use of such a green adsorbent for the treatment of organic-pollutants-rich industrial wastewaters promotes sustainability and circular economy concepts.
Access to Employer Benefits and Financial Insecurity Among Frontline Healthcare Workers
Authors: Despard Mathieu R. , Zheng Haotian , Fox-Dichter Sophia
Published: July 2023

Concern is growing about financial stress among U.S. workers, many of whom experience financial insecurity (FIS) as they struggle to make ends meet, manage debt, and save. Benefits comprise almost a third of total compensation and affects hiring and retention, which is important with respect to the shortage of frontline healthcare workers (FHWs). We present results from a survey of 2321 FHWs, finding that FHWs without college degrees and working in home health and private duty settings have lower access to benefits and greater FIS compared to those with college degrees and who work in facility-based settings. Among all FHWs, access to benefits has a strong association with FIS, even while controlling for income. Our findings suggest that employers consider improving benefits to help address FIS and within healthcare, address issues of compensation equity based on educational attainment. Still, addressing worker FIS may take strengthening the public social safety net.
Editorial: Youth personality development

Published: July 2023

The period between childhood and adulthood is a turbulent time of life (Hollenstein & Lougheed, 2013). While there is a solid body of research on youth social, biological, and psychological development (Sawyer et al., 2018; Steinberg & Morris, 2001), surprisingly little is known about personality processes and individual differences in them during these years. The papers in this Special Issue make important contributions to the current literature in three ways: first, by mapping developmental patterns to broader conceptualizations of personality, including personality pathology, second, by examining predictors and mechanisms in youth personality development, and third, by linking youth personality development to later life outcomes. We hope that the results of these papers will contribute to a more nuanced understanding of adolescent personality development in diverse cultural contexts and stimulate new integrative research.

Published: July 2023

Accurate prediction of the remaining useful life for the cutting tool is a key part of the predictive maintenance of computer numerical control machines. However, the wide variety of tools makes the process of modeling different tool wear regularities redundant and cumbersome. In addition, it is difficult to deal with the input characteristics of multi-sensor monitoring signals in a targeted manner. To solve the above problems, a hybrid predictive model with squeeze-and-excitation (SE) module is proposed. Combined with adaptive feature extraction based on convolutional neural network and observation based on bidirectional gated recurrent unit, accurate multivariate regression prediction is achieved. The SE module enhances the focus on crucial features. Finally, through the design of the tool wear experiment and the combination of the public dataset, the accuracy and generalization ability of the proposed model are verified under different tool types and different working conditions.
Experimental investigation on the machining performance of AISI D2 tool steel during ultrasonic-assisted turning under dry and MQL conditions
Authors: Umasekar Venugopal Gurusamy , Stalin John Maria Robert
Published: July 2023

Ultrasonic-assisted turning (UAT) is a hybrid machining method that improves difficult-to-cut materials’ machinability and surface integrity. Minimum quantity lubrication (MQL) is a cooling condition employed in metal cutting operations to improve machining performance and environmental sustainability. This article presents the experimental investigations on the effect of machining and vibration parameters and cooling conditions on the surface roughness (Ra), flank wear (Vb), and surface hardness (HV) during UAT of AISI D2 tool steel. Experiments were designed based on L36 orthogonal array. Two levels of spindle speeds, feed rates, depth of cut, and three levels of percentage intensity of ultrasonic power (PIUP) were employed, and two cooling conditions, like dry and MQL. Analysis of variance (ANOVA) was used to find the significant input parameters that affect each response. ANOVA output revealed that feed rate was the most influential factor on Ra, the PUIP is the dominant factor on HV, and spindle speed is the significant factor on Vb. Optimisation is performed to find optimal parameters as per Taguchi multi-response method. The optimal parameters are 450 rpm spindle speed, 0.05 mm/rev feed rate, 0.1 mm depth of cut, 100 PIUP and MQL cooling resulted in minimum surface roughness of 0.439 μm, maximum hardness of 283 HV and minimum flank wear of 168 μm. Flank wear morphology results showed that abrasion and chipping are the tool wear mechanism in dry UAT, whereas minor abrasion alone was found in MQL UAT compared to CT. Chip morphology study showed that UAT produced continuous spiral-type chips under both cooling conditions compared to CT. A novel design approach is implemented to design the UAT tool. Along with the UAT tool, MQL is also given to improve the machinability of D2 tool steel. This UAT tool can machine intricate metals with a critical cutting velocity of less than 75.4 m/min.

Authors: Pazarlıoğlu Hayati Kadir , Tepe Ahmet Ümit , Arslan Kamil
Published: July 2023

In this study, anti-icing problems, which are mostly industrial problems in aerospace companies, have been numerically investigated. Herein, to enhance anti-icing performance of NACA0015, different jet-to-surface distances ( H/d), jet angles ( α), and slot jet designs with different aspect ratios ( ARs) have also been investigated. ANSYS Fluent 2020R2 commercial program has been utilized for all numerical calculations. In addition, the SST k-ω with low-Re correction wall treatment turbulence model has been used for solving turbulence equation. Furthermore, the average Nusselt number ( Nu) on the NACA0015's surface, pressure drop, and performance evaluation criteria (PEC) which define the anti-icing performance of novel proposed system have been presented section by section. As a result of the investigation, it has been obtained that the use of AR = 4 increases the Nu by 85.52% compared to circular jet for the H/d = 4 at α = 90°. The pressure drop value dramatically increases using AR = 4 around 307.85% compared to circular jet for H/d = 4 at α = 90°. Despite this drastic increment in pressure drop, the PEC value is kept as 1.14 using AR = 4, H/d = 4, and α = 90°. Finally, empirical correlations developed from existing findings have been presented with an error rate of lower than 5%.

Published: July 2023

This article investigates the impact of moisture and temperature on vibration characteristics of bio-composite skew-laminated composite sandwich (SLCS) plates. The bio-composite SLCS plates with bamboo face sheets and polylactic acid (PLA) cores are biodegradable, radiolucent, lightweight, high strength, and withstand vibrations. The coupled thermo-elastic and hygro-elastic finite element (FE) model of the SLCS plate is derived using the higher-order shear deformation theory (HSDT). An initial stress stiffness matrix is developed using the nonlinear strain-displacement relations to incorporate the effect of temperature and moisture in FE modeling. Temperature and moisture-dependent material properties of bamboo fiber-reinforced biocomposite (BFB) and PLA core are employed for the analysis. A comprehensive investigation has been carried out to study the impact of moisture and temperature situations with different geometrical parameters and various skew angles on the frequency of the SLCS plate. The results indicate that the biocomposite sandwich material has excellent potential for structural applications under different environmental conditions in various applications like food processing, and biomedical applications, including MRI and CT scan beds.
Residents’ experiences of paternalism in nursing homes
Authors: Mortensen Anne Helene , Nåden Dagfinn , Karterud Dag , Lohne Vibeke
Published: July 2023

Background

Interest in strengthening residents’ autonomy in nursing homes is intensifying and professional caregivers’ experience ethical dilemmas when the principles of beneficence and autonomy conflict. This increased focus requires expanded knowledge of how residents experience decision-making in nursing homes and how being subject to paternalism affects residents’ dignity.

Research question/aim

This study explored how residents experience paternalism in nursing homes.

Research design

This study involved a qualitative interpretive design with participant observations and semi-structured interviews. The interpretations were informed by Gadamer’s hermeneutics.

Participants and research context

Eleven residents were interviewed after a period of participant observation in two nursing homes.

Ethical considerations

The study was performed in accordance with the Helsinki declaration. The Regional Ethics Committee (REK) permitted the researcher to perform participant observation in the nursing homes. The use of audio recordings of interviews was registered and supervised by Sikt - Norwegian Agency for Shared Services in Education and Research. The resident’s consent was assessed continuously. Three interviews were terminated for ethical reasons.

Findings

The resident interviews revealed that residents found it obvious for caregivers to possess the decision-making authority in nursing homes. When residents explained their views, three main themes emerged: (1) To be included even though caregivers make the decisions, (2) Surrender to dependency, and (3) Adherence to nursing home norms.

Conclusions

Residents submit to their caregivers and give caregivers the responsibility and function as leaders. Paternalism was experienced as dignifying in situations where it contributed to residents being able to live according to second order desires and values, and when it implied respect and appraisal of residents’ capabilities. Paternalism was experienced as debasing when residents felt left out, and when residents felt that their capabilities were underestimated. This also included their capability to withstand paternalistic influence.

Authors: Dhir Swati , Mohapatra Mamta , Srivastava Shalini
Published: July 2023

Workplace loneliness is the perception of relationship deficit in any organization which hampers the employee’s psychological well-being, which is an essential attribute for overall organizational performance. The objective of this study is to understand the effect of workplace loneliness and perceived organizational support on psychological well-being and the moderating effect of resilience on psychological well-being. The study has gathered 391 data points from various working executives in different organizations in India. The data have been analysed by using Partial Least Square Structural Equation Modelling (PLS-SEM). The results have shown a negative association between workplace loneliness and a positive association with perceived organizational support for psychological well-being. It has also been exhibited that resilient employees discount the perception of loneliness in the workplace. The results of this study will certainly help organizations design their policies for supporting employees and develop resilient employees through necessary interventions. The study is unique in highlighting the effect of one of the negative workplace attributes and the essential ways to overcome the same in a single study.

Published: July 2023

The communication channels driving misinformation often carry the misinformation to elicit responses, which can turn into big threats. Users’ extensive availability and convenience in creating and facilitating user-provided content in online social media enable people with common interests, worldviews and narratives to come together and spread information/misinformation. This research aims to create an intellectual structure through reflective analysis that will help us identify the existing communication pattern that led to misinformation during recent times, also considering the pandemic times. This study analyses and reviews the emerging literature on misinformation using a bibliometric analysis approach. A total of 1,363 papers published from January 2008 to June 2022 from the Scopus database were extracted for analysis in VOS viewer, revealing 10 clusters derived from the keyword, finally coming under four broad themes.

The findings revealed that the earlier studies in this area were more expressive and theoretical, and there is a need to provide simple and scientific solutions to counter the misinformation. Considering all possible adversities, this article draws concrete conclusions by offering directions and propositions to create more comprehensive systems and policies to drive a conclusive future.
Time-harmonic loading over a piezoelectric layered half-space
Authors: Nirwal Sonal , Lin Chih-Ping , Tran Quoc Kinh , Pan Ernian
Published: July 2023

Mathematical modeling of multilayered piezoelectric (PE) ceramic substantially acquires attention due to its distinctive advantages of fast response time, positioning, optical systems, vibration feedback, and sensors, such as deformation and vibration control. As such, fundamental solution of a PE structure is essential. This paper presents three-dimensional (3D) static and dynamic solutions (i.e. Green’s functions) in a multilayered transversally isotropic (TI) PE layered half-space. The uniform vertical mechanical load, vertical electrical displacement, and horizontal mechanical load are applied on the surface of the structure. The novel Fourier-Bessel series (FBS) system of vector functions (which is computationally more powerful and streamlined) and the dual-variable and position (DVP) method are employed to solve the related boundary-value problem. Two systems of first-order ordinary differential equations (i.e. the LM- and N-types) are obtained in terms of the FBS system of vector functions, with these expansion coefficients being the Love numbers. A recursive relation for the expansion coefficients is established by using DVP method that facilitates the combination of two neighboring layers into a new one and minimizes the computational effort to a great extent. The corresponding physical-domain solutions are acquired by applying the appropriate boundary/interface conditions. Several numerical examples pertaining to static and dynamic response are solved, and the efficiency and accuracy of the proposed solutions are validated with the existing results for the reduced cases. The solutions provided could be beneficial to better developments of PE materials, configurations, fabrication, and applications in the future.

In this paper, we propose a novel two-degree-of-freedom (TDOF) nonlinear energy harvester without internal resonance to realize broadband harvesting characteristic. To show the performance, a TDOF nonlinear electromagnetic harvester is designed. The electromechanical coupling system is established and solved by adopting the harmonic balance method. The modulation equations are constructed, the first-order harmonic solutions of the system are obtained and the frequency response curves of the displacement and current are plotted. The advantage of the proposed harvester is compared to the conventional single-degree-of-freedom (SDOF) nonlinear model and the corresponding TDOF linear system, the results achieve that the proposed scheme can enhance the bandwidth of the harvesting energy. Furthermore, the influences of system parameters on the response are discussed. The accuracy of the first-order harmonic results is revealed by numerical simulations. To further demonstrate the accuracy of analytical solutions, the finite element simulation is constructed in ANSYS finite element analysis (FEA) software. The performance predictions from the analytical solutions are compared with results from FEA. It is convincingly demonstrated that periodic solutions have a degree of good consistency for the behavior of frequency response curves.

The aim of this study was to characterize the network structure of grief-related functional impairment symptoms as measured by The Grief Impairment Scale (GIS) in 520 Peruvian individuals who have experienced the death of a family member or loved one. A psychological network model was applied to evaluate the estimation, stability, and accuracy of the network during the analysis sequence. The results indicated that the inability to perform activities at work, school, or home was the most central symptom in the entire network. However, the presence of high instability in the centrality indices indicates that the central node may differ in other cultural contexts. The networks were invariant according to sex. The most influential node in the women's group was their inability to perform activities at work, school, or home. In men, the most central node was the presence of health problems due to bereavement. The results would help to better understand functional impairment due to bereavement

The present study aimed to assess the mediating role of adjustment processes in known risk factors associated with prolonged grief disorder. Data were collected in March–April 2021 through an online survey of 542 Canadian adults bereaved since March 2020. The mediating role of satisfaction with funeral rituals, bereavement support, and coping strategies on grief outcomes was tested using structural equation modeling. Results showed that such adjustment processes played a significant role in the grief process and that they were better predictors than risk factors alone. Since they are more amenable determinants of grief reactions, they should be further studied using a longitudinal design.
Organizing Creativity With Constraints—Insights From Popular Music Songwriting Teams
Authors: Theel Tobias , Sydow Jörg
Published: July 2023

Creative processes within and across organizations have not only been associated with freedom but also with constraints. By taking a dialectical process perspective, we examine how creatives actually engage with constraints and how constraints thereby emerge, unfold and terminate over time. Based on ethnographic observations and interviews with popular music songwriting teams, we found that collaborators do not simply experience but also actively utilize constraints. Doing so enables songwriters to process constraints and to organize for an oscillation between stable, generative, and flexible constraint characterizations, fueling the creative process. Notwithstanding the persistent nature of some structural constraints, these findings contribute to research on organizing creativity by conceptualizing constraints as intertwined, malleable and even transformable by actors as they unfold. Thereby, the findings extend the current understanding of creativity with constraints by pointing to the crucial role of certain constraint characterizations that need to alternate procedurally between stability and fluidity.
A Real-World Disproportionality Analysis of Drug-Induced Immune Hemolytic Anemia in the FDA Adverse Event Reporting System

Published: July 2023

Background:

Drug-induced immune hemolytic anemia (DIIHA) is a rare but potentially life-threatening pharmacogenic hematological adverse effect. Updating the risk of DIIHA among the currently available drugs based on spontaneously reported adverse event data is of great significance.

Objective:

This study aimed to identify the top 50 drugs associated with immune hemolytic anemia in adults as well as common drugs that could cause immune hemolytic anemia in children based on the United States Food and Drug Administration Adverse Event Reporting System (FAERS) database.

Methods:

We extracted adverse events (AE) in the FAERS database from Q1 2004 to Q3 2022 using Open vigil2.1. We use the high-level term “anaemias haemolytic immune” according to the Medical Dictionary for Regulatory Activities (MedDRA) Dictionary (version 24.0). The reported correlation between drugs and DIIHA risk was identified by reported odds ratio (ROR) and proportional reporting ratio (PRR).

Results:

There were 10500309 AEs in FAERS from 2004Q1 to 2022Q3, of which 2326 (0.02%) were DIIHA cases. The incidence of DIIHA is comparable between males and females. The most common drugs associated with DIIHA in adults and children are summarized according to the number of AE reports. The top 3 categories in terms of quantity of drugs are antineoplastic agents, immunosuppressants, and antibiotics for systemic use. The top 5 drugs in terms of ROR and PRR are alemtuzumab, daclizumab, fludarabine, busulfan, and bendamustine in adults, with entecavir, treosulfan, vinorelbine, pegademase, and alemtuzumab for children.

Conclusions:

Our study identified the most common drugs that could induce DIIHA in adults and children, as well as the respective ROR and PRR value to discover new drug signals. This study provides references to clinicians for the management of rare DIIHA.
Applying Frasier Four A’s to Promote Upstander Teachers for Academic Acceleration of Gifted Black Students
Authors: Luckey Goudelock Jessa , Grantham Tarek
Published: July 2023

Acceleration is an effective approach for many high ability students, and it can be especially beneficial for Black students. Upstander teachers are those who recognize educational crises and the problem of overlooked and underdeveloped gifts and talents of Black students in regular and gifted education programs. They proactively identify Black students’ intellectual and academic strengths and plan not only enrichment services, but accelerated pathways for Black students to be appropriately challenged. Too many Black students with gifts and talents succumb to boredom, underachievement, and atrophy when bystander teachers have low academic expectations of them and fail to recommend them for academically rigorous advanced and accelerated learning experiences. The purpose of this article is to present acceleration as a means of creating equitable opportunities in gifted education for gifted Black students using Frasier’s Four A’s framework: attitude, access, assessment, and accommodation. Specifically, the following questions are addressed: What are upstander attitudes toward acceleration and related policies? How can upstander teachers know if a Black student is a good candidate for acceleration and increase their access to acceleration? How can upstander teachers provide equitable assessments of Black students for acceleration? What can upstander teachers do to support acceleration programming that accommodates the needs of gifted Black students? Six tables provide an overview of acceleration types, a guide to promote equitable acceleration, and considerations for accelerating gifted Black students.
