Personality and universal design for learning in management education
Authors: Sanford Douglas , Tabak Filiz 
Published: February 2023

Purpose
This paper aims to improve the understanding of student readiness for universal design for learning (UDL), thereby reducing a barrier to its adoption by management faculty. It explores how students’ personality (conscientiousness and openness to experience) affects their readiness to embrace UDL and investigate how that relationship is mediated by self-directed learning (SDL).

Design/methodology/approach
Analysis uses survey data from students in management courses. From these data are created multi-item constructs and control variables. A mediated regression model that uses bootstrapping to estimate parameters and standard errors generates the results.

Findings
The findings were that SDL is strongly related to student readiness for UDL and that SDL fully mediates the relationship between conscientiousness and UDL. Openness to experience, however, directly relates to UDL without any mediation.

Research limitations/implications
This research applies only to one institution and two management courses. The methodology used in this study is limited to one part of the UDL model, which is a measure of student readiness to engage in choice. Future research can extend this model to other courses and institutions and other parts of the UDL model.

Practical implications
These findings provide insight into the student characteristics that enable them to gain empowerment and motivation from the UDL approach. Implementation of UDL in management education may require learning management strategies that accommodate student readiness for UDL. This study makes progress in identifying student characteristics that explain this readiness.

Social implications
UDL can improve management education by making it more accessible to students with different personalities and learning styles.

Originality/value
This study developed a method for analyzing the applicability of UDL in management education. It also devised and implemented a new survey measure for student readiness for UDL.

Authors: Chen Yunan , Sun Ivan , Wu Yuning , Han Ziqiang 
Published: February 2023

PurposeThe purpose of this paper is to assesses whether supervisor justice is linked to COVID-19 negative and positive impacts directly and indirectly through the mechanisms of stress and resiliency among auxiliary police in China.Design/methodology/approachThis study utilized survey data from more than 300 auxiliary police in a large Chinese provincial capital city in 2020. Structural equation modeling was conducted to analyze the direct and indirect relationships between supervisor justice and COIVD-19 impacts.FindingsResults indicate that supervisor justice connects to COVID-19 negative impacts indirectly through stress. Supervisor justice is also indirectly related to positive impact through resiliency.Research limitations/implicationsThe findings' generalizability is limited due to using a nonrandom sample of officers. Officers' emotional states in the forms of stress and resiliency are important in mediating the association between supervisory justice and COVID-19 impacts.Originality/valueThe present study represents one of the first attempts to empirically investigate the occupational experiences of a vital group of frontline workers in Chinese policing. This study also generates evidence to support the importance of officers' emotional conditions in reducing negative COVID-19 impacts in an authoritarian country.
A systematic review on well-being and ill-being in working contexts: contributions of self-determination theory
Authors: Nunes Paula Martins , Proença Teresa , Carozzo-Todaro Mauro Enrique 
Published: February 2023

PurposeNo systematic review has previously been dedicated to comprehensively investigate predictors of well-being and ill-being in working contexts. Empirical studies have vastly associated well-being as the result of autonomous motivation and basic psychological needs satisfaction, while frustration results in ill-being. The purpose of this study is to integrate the variables identified in empirical studies associated with the occurrence of the phenomena, individual/organizational features and consequences associated with workers' well-being/ill-being.Design/methodology/approachThis systematic review includes 44 empirical studies published up to February 2021. Findings are summarized based on quantitative analysis of the evidence.FindingsResults reinforce the role of self-determined motivation and needs satisfaction in promoting well-being, while amotivation and needs frustration led to ill-being. Besides, they indicate that ill-being can both lead to negative consequences and diminish positive work outcomes. Findings also revealed that: integrated motivation does not seem to be empirically distinct from intrinsic and identified motivation in promoting well-being; introjected motivated behaviors may be less harmful to psychological health than externally oriented ones; the relationship between external motivation and well-being/ill-being requires prospective investigations; and amotivation seems to have a detrimental effect in workers' psychological health.Practical implicationsResults provide practical information for HRM practitioners to design work environments and practices that promote employees' psychological health.Originality/valueAn unprecedented framework that aggregates empirical findings regarding the antecedents, predictors and consequences of ill-being/well-being in working contexts is presented.
Highly efficient elimination of uranium (VI) and thorium (IV) from aqueous solution using activated carbon immobilized on polystyrene
Authors: Elhefnawy O.A. , Elabd A.A. 
Published: February 2023

Purpose
The purpose of this study is to prepare a new adsorbent activated carbon immobilized on polystyrene (ACPS) for uranium (VI) and thorium (IV) removal from an aqueous solution. Activated carbon (AC) was derived from biochar material by chemical activation to increase the active sites on its surface and enhance the adsorption capacity. Activated carbon (AC) was immobilized on polystyrene (PS) to improve the physical properties and facilitate separation from the working solution. A feasibility study for the adsorption of uranium (VI) and thorium (IV) on the new adsorbent (ACPS) has been achieved. Adsorption kinetics, isotherms, and thermodynamics models of the adsorption process were used to describe the reaction mechanism.

Design/methodology/approach
Activated carbon was synthesized from biochar charcoal by 2 M H2SO4. Activated carbon was immobilized on the pretreatment polystyrene by hydrothermal process forming new adsorbent (ACPS). Characterization studies were carried out by scanning electron microscope, energy-dispersive X-ray spectrometer, infrared spectroscopy and X-ray diffraction techniques. Different factors affect the adsorption process as pH, contact time, solid/liquid ratio, initial concentration and temperature. The adsorption mechanism was explained according to kinetic, isothermal and thermodynamic studies. Also, the regeneration of spent ACPS was studied.

Findings
The experimental results showed that pH and equilibrium time of the best adsorption were 6.0 and 60 min for U(VI), 4.0 and 90 min for Th(IV), (pHPZC = 3.4). The experimental results fit well with pseudo-second order, Freundlich and Dubinin–Radushkevich models proving the chemisorption and heterogenous adsorption reaction. Adsorption thermodynamics demonstrated that the adsorption process is exothermic and has random nature of the solid/liquid interface. In addition, the regeneration of spent ACPS research showed that the adsorbent has good chemical stability. According to the comparative study, ACPS shows higher adsorption capacities of U(VI) and Th(IV) than other previous bio-adsorbents.

Originality/value
This study was conducted to improve the chemical and physical properties of bio-charcoal purchased from the local market to activated carbon by hydrothermal method. Activated carbon was immobilized on polystyrene forming new adsorbent ACPS for eliminating U(VI) and Th(IV) from aqueous solutions.
Evaluation of the anti-erosion performance of PLA and ABS materials with two different micro textures
Authors: Singh Sidhu Ripendeep , Singh Gurmeet , Gill Harjot Singh 
Published: February 2023

Purpose
This empirical study aims to investigate the erosion wear performance of two different 3D-printed materials (acrylonitrile butadiene styrene [ABS] and polylactic acid [PLA]) with various micro textures. The two different textures (prism and square) were created over the surfaces of both materials by using the 3D-printed technique.

Design/methodology/approach
The erosion experiments on both materials were performed by using Ducom Erosion Jet Tester. Erosion tests were performed at four different impacting velocities (15, 30, 45 and 60 m/s) with the four different particle sizes (17, 39, 63 97 µm) at the impact angles (30°–90°) for the time duration of 5, 10, 15 and 20 min. The two different textures prism and cone were used for performing the erosion experiments. Taguchi’s orthogonal L16 (mixed level) was used to reduce the number of experiments and to determine the impact of these parameters on erosion wear performance of both 3D-printed materials.

Findings
The PLA with cone texture was found to be best (against erosion) than the ABS cone and prism textures due to their high hardness (68 HV). Also, the average signal to noise (S/N) ratio for PLA and ABS was measured as 56.4 and 44.4 dB, respectively. As the value of the S/N ratio is inversely proportional to the erosion rate, the PLA has the least erosion rate as compared to the ABS. The sequence of erosion wear influencing parameters for both materials was in the following order: velocity > erodent size > texture > impact angle > time interval.

Originality/value
Both PLA and ABS with different micro textures for erosion testing were studied with Taguchi’s optimization method, and the erosion mechanisms are well analyzed by using scanning electron microscopy and Image J techniques.
Ground-level documentation of heat stress exposure and response strategies in informal settlements in Tshwane, South Africa
Authors: Hugo Jan Marais , Sonnendecker Paul Walter 
Published: February 2023

PurposeThe adverse impacts of climate change coupled with rapid informal urbanization in the Southern African region are increasing the vulnerability of already sensitive population groups. Consequently, these urban regions are highly vulnerable to urban heat island effects and heatwaves due to exogenous and endogenous factors. While the dynamic interplay between the built environment, climate and response strategies is known, this paper highlights the lived experience of informal settlement residents. It presents work from a project undertaken in Melusi, an informal settlement in Tshwane, South Africa, as a multi-disciplinary project focusing on improving the local resilience to climate change associated heat stress.Design/methodology/approachFollowing a mixed method approach, a semi-structured observational analysis of the spatial layout and material articulation of selected dwellings along with the continuous monitoring and recording of their indoor environments were undertaken.FindingsThe paper presents the research results in terms of the dwelling characteristics, as spatial and material-use strategies and documented heat stress exposure in these structures. The findings highlight that informal dwellings perform poorly in all cases due to endogenous factors and that inhabitants experience extreme heat stress conditions for between 6 and 10 h daily during the peak summer period.Originality/valueCurrently, there are little empirical data on the heat stress residents living in informal settlements in Southern Africa are experiencing. This article provides insight into the indoor environments of informal dwellings and hopes to contribute future guidelines or heat health policies.
Behavioural intention and satisfaction levels among pilgrim tourists in South Asia
Authors: Wani Mehraj Din , Dada Zubair Ahmad , Shah Shamim Ahmad 
Published: February 2023

Purpose
This paper aims to analyse the influence of perceived value (PV), sensation seeking (SS) and low crowding (LC) on the satisfaction and behavioural intention (BI) of Indian pilgrim tourists to Kartarpur Corridor, Pakistan. In addition, it identifies the mediation effect of satisfaction in the structural relationship between PV, SS and LC as exogenous variables and BI as an endogenous variable.

Design/methodology/approach
By using convenience sampling, out of 510 questionnaires distributed among the Indian pilgrim tourists returning from Kartarpur Sahib, Pakistan, a total of 404 completely filled surveys were used to evaluate the robustness of the theoretical framework. Data analysis and empirical testing of the suggested model are conducted using descriptive statistics, confirmatory factor analysis and structural equation modelling.

Findings
The results reveal that PV, SS and LC positively affect the satisfaction of tourists crossing an international boundary, while satisfaction is the positive and significant antecedent of BI. Moreover, the indirect effects of PV, SS and LC on BI via satisfaction are found to be significant.

Originality/value
The previous literature has not paid much attention to the satisfaction and BI of tourists crossing an international border. The present article contributes to the existing volume of knowledge related to the satisfaction and BI of cross-border tourists. The study results may be useful for tourism marketers to better understand the factors that affect the satisfaction and BI of cross-border tourists.
γδ T‐cell–mediated immune responses to malaria
Authors: Bayarsaikhan Ganchimeg , Ibraheem Yarob , Inoue Shin‐Ichi 
Published: February 2023

AbstractMalaria is one of the deadliest infectious diseases. Licensed vaccine have demonstrated just over 30% efficacy, and therefore, developing new vaccine candidates and understanding immune responses to Plasmodium have become necessary. γδ T cells have been suggested to be associated with immune responses to malaria due to the observation of their expansion in patients with malaria and experimental models of malaria. γδ T cells act as both “innate‐like” and “adaptive‐like” cells during immune response to malaria. Studies have found that γδ T cells can recognize Plasmodium phosphoantigen, present the antigen, and initiate adaptive immune response during blood‐stage Plasmodium infection. Recent reports also suggested the phagocytic and cytotoxic potential of γδ T cells. Furthermore, γδ T cells can provide protection upon immunization with whole parasite. In addition, γδ T cells during the liver‐stage infection were able to prevent experimental cerebral malaria. Despite these new findings, questions related to γδ T‐cell response during Plasmodium infection remain to be answered. However, investigating these cells in humans remains difficult in many ways; in this regard, rodent models of malarial infection enable us to study these cells in more detail. Insights from experimental malaria models give rise to new cues for development of malarial vaccine and adjunctive therapy for severe malaria. Here, we review our current knowledge of γδ T‐cell immune function in human and experimental mouse malarial infection models; especially, we focus on the mechanisms underlying γδ T cells that are associated with protective immunity during malarial infection.
Gender inequality in the one percent: A look under the hood of high incomes in Germany
Authors: Collischon Matthias 
Published: February 2023

AbstractGender differences in economic outcomes are important topics in social science research. However, the study of gender differences among economic elites—“the top one percent”—has received surprisingly little attention, likely also due to a lack of empirical data. This paper investigates gender differences in individual and household income among the top one percent of individual monthly net incomes and top two percent of net household incomes using data from the German Microcensus from 2006 to 2016 covering more than 3.3 million individuals. I find that women account for only around 14% of the one percent in individual incomes. Additionally, regarding the household level, women's incomes are sufficient to achieve two percent status in fewer than 10% of all households. Both numbers did hardly change over the decade from 2006 to 2016. Furthermore, women's pathways to belonging to a high‐income household are far more dependent on their partner's education and employment status than men's. Overall, the findings thus show dramatic gender differences among the German economic elite that do not narrow over time.

Published: February 2023

AbstractBackgroundDespite the importance of rehabilitation nursing care in improving patient outcomes, the provision of this care in the early stages of diseases and injuries is limited. In this situation, analyzing the concept of rehabilitation nursing care can increase nurses’ understanding of this concept and improve the provision of rehabilitation nursing care in the acute phase. This study aimed to analyze the concept of rehabilitation nursing care in acute phase of diseases with physical disability.MethodWalker and Avant's approach to concept analysis was performed in eight stages, including choosing a concept, determining the purpose of analysis, identifying all uses of the concept, defining attributes, identifying a model case, identifying borderline and contrary cases, identifying antecedents and consequences, and defining empirical referents.ResultsThe important characteristics of rehabilitation nursing are comprehensive, education‐based, specialized, client and family centered, interprofessional, and need‐based. The antecedents of rehabilitation nursing care are related to nurses, the care settings and the nursing profession. The most important consequence of rehabilitation nursing care is improving the quality of life of patients. Rehabilitation nursing care also has positive outcomes for nurses and the healthcare systems.ConclusionThe findings indicate that rehabilitation nursing care has several attributes that require antecedents such as knowledge and specialized skills such as teamwork skills, effective communication skills, cultural sensitivity, holistic perspective, intuitive thinking, and reasoning. The most important consequence of rehabilitation nursing care is improving the quality of life of patients.

Published: February 2023

AbstractDiverse mouse strains have different health and life spans, mimicking the diversity among humans. To capture conserved aging signatures, we studied long‐lived C57BL/6J and short‐lived NZO/HILtJ mouse strains by profiling transcriptomes and epigenomes of immune cells from peripheral blood and the spleen from young and old mice. Transcriptional activation of the AP‐1 transcription factor complex, particularly Fos, Junb, and Jun genes, was the most significant and conserved aging signature across tissues and strains. ATAC‐seq data analyses showed that the chromatin around these genes was more accessible with age and there were significantly more binding sites for these TFs with age across all studied tissues, targeting pro‐inflammatory molecules including Il6. Age‐related increases in binding sites of JUN and FOS factors were also conserved in human peripheral blood ATAC‐seq data. Single‐cell RNA‐seq data from the mouse aging cell atlas Tabula Muris Senis showed that the expression of these genes increased with age in B, T, NK cells, and macrophages, with macrophages from old mice expressing these molecules more abundantly than other cells. Functional data showed that upon myeloid cell activation via poly(I:C), the levels of JUN protein and its binding activity increased more significantly in spleen cells from old compared to young mice. In addition, upon activation, old cells produced more IL6 compared to young cells. In sum, we showed that the aging‐related transcriptional activation of Jun and Fos family members in AP‐1 complex is conserved across immune tissues and long‐ and short‐living mouse strains, possibly contributing to increased inflammation with age.
Sclerostin blockade promotes bone metastases of Wnt‐responsive breast cancer cells

Published: February 2023

AbstractThe secreted protein sclerostin is primarily produced by osteocytes and suppresses osteoblast differentiation and function by inhibiting the canonical Wnt signaling pathway. Genetic and pharmacological inhibition of sclerostin has been shown to increase bone formation and an anti‐sclerostin antibody has been clinically approved for the treatment of osteoporosis. Canonical Wnt signaling is also involved in the progression of several types of cancers including breast cancer. Here, we studied the effects of sclerostin inhibition on the development of bone metastases of breast cancer using mouse models. TOPFLASH assay and real‐time PCR analysis of AXIN2, a target of canonical Wnt signaling, revealed that, among four cell lines tested, MDA‐MB‐231 human breast cancer cells responded highly to the canonical Wnt ligand Wnt3a, whereas other cell lines exhibited marginal responses. Consistent with these results, treatment with an anti‐sclerostin antibody significantly increased the bone metastases of MDA‐MB‐231 but not those of other breast cancer cells. Immunohistochemical studies demonstrated that an anti‐sclerostin antibody induced intracellular accumulation of β‐catenin in bone‐colonized MDA‐MB‐231 cells. Suspension culture assays showed that Wnt3a accelerated the tumorsphere formation of MDA‐MB‐231 cells, whereas monolayer cell proliferation and migration were not affected. Furthermore, the numbers of osteoclasts and their precursor cells in bone metastases of MDA‐MB‐231 were significantly increased in mice treated with an anti‐sclerostin antibody. These results collectively suggest that sclerostin blockade activates canonical Wnt signaling in ligand‐responsive breast cancer cells metastasized to bone, thereby increasing bone metastases, likely to have been mediated at least in part by enhancing stem cell‐like properties of cancer cells and osteoclastogenesis.
