Published: September 2023

ABSTRACTObjectiveBmp6knockout (KO) mice progressively accumulate a significant amount of iron in their liver as they age due to a defect in hepcidin (Hamp) expression and an upregulation of the iron exporter ferroportin (Fpn). In this study, we conducted a comprehensive investigation of the hepatic iron overload phenotype, with specific emphasis on the cellular and subcellular localization of Fpn inBmp6KO mice.Materials and MethodsLivers obtained fromBmp6knockout (KO) mice at different developmental stages were utilized for the quantification of iron content, investigation of iron distribution, histological analysis, histoimmunofluorescence assays performed on paraffin-embedded sections, confocal microscopy examinations, subcellular membrane fractionation, and western blot analysis.ResultsInBmp6KO livers, iron overload increased with age and was not homogeneous, with certain hepatic lobes and specific areas in liver sections showing more pronounced iron accumulation. In young mice, iron accumulated mostly in the centrilobular zone where low Fpn expression was observed. Fpn was strongly detected in periportal Kupffer cells and at the apical membrane of periportal hepatocytes lining the sinusoidal capillaries. The zonal distribution of iron tended to disappear with age in strongly iron-overloaded areas, with the appearance of large cellular aggregates strongly positive for Fpn, iron, and ceroid/lipofuscin. At the subcellular level, hepatic Fpn seemed to concentrate in specific cell surface compartments and was enriched in a lipid raft fraction.ConclusionsUnregulated expression of Fpn on the cell surface of periportal macrophages and hepatocytes results in centrilobular iron overload within hepatocytes. In areas of pronounced iron overload, Fpn expression is present in lipogranulomas, identified as aggregations of macrophages accumulating hemosiderin and ceroid/lipofuscin pigments. These lesions likely form due to the phagocytosis of sideronecrotic/ferroptotic hepatocytes by macrophages. In contrast to the duodenal form of Fpn, both splenic and hepatic Fpn demonstrated robust enrichment within lipid rafts. The observed variations in the subcellular localization of Fpn could play a significant role in influencing the transporter’s iron transport activity and/or its regulation by hepcidin.
Facilitation of sensorimotor temporal recalibration mechanisms by cerebellar tDCS in patients with schizophrenia spectrum disorder and healthy subjects
Authors: Schmitter Christina V. , Straube Benjamin 
Published: September 2023

AbstractCore symptoms in patients with schizophrenia spectrum disorder (SSD), such as hallucinations or ego-disturbances, have been associated with a failure of the forward model to adequately predict the sensory outcomes of self-generated actions. Importantly, depending on the requirements of the environment, forward model predictions must also be able to recalibrate flexibly, for example to account for additional delays between action and outcome. In this study, we aimed to investigate whether non-invasive brain stimulation via transcranial direct current stimulation (tDCS) can be used to improve these sensorimotor temporal recalibration mechanisms in patients and in healthy subjects.While receiving tDCS on the cerebellum, temporo-parietal junction (TPJ), supplementary motor area (SMA), or sham stimulation, patients with SSD and healthy control subjects were repeatedly exposed to delays between actively elicited or passively performed button press movements and auditory sensory outcomes. Effects of this procedure on temporal perception were assessed with a delay detection task.We found similar sensorimotor temporal recalibration effects in both SSD and healthy subjects. Furthermore, cerebellar tDCS facilitated recalibration effects in both groups.Our findings indicate that sensorimotor recalibration mechanisms may be preserved in SSD and highlight the importance of the cerebellum in both patients and healthy subjects for this process. Our results suggest that cerebellar tDCS could be a promising tool for addressing deficits in action-outcome monitoring and related adaptive sensorimotor processes in SSD, and potentially alleviating associated symptoms.
Measuring and increasing rates of self-isolation in the context of infectious diseases: A systematic review with narrative synthesis

Published: September 2023

AbstractBackgroundSelf-isolation was used to prevent the spread of COVID-19 and will likely be used in future infectious disease outbreaks.MethodWe conducted a systematic review following PRISMA and SWiM guidelines. MEDLINE, PsycINFO, Embase, Web of Science, PsyArXiv, medRxiv, and grey literature sources were searched (1 January 2020 to 13 December 2022) using terms related to COVID-19, isolation, and adherence. Studies were included if they contained original, quantitative data of self-isolation adherence during the COVID-19 pandemic. We extracted definitions of self-isolation, measures used to quantify adherence, adherence rates, and factors associated with adherence. The review was registered on PROSPERO (CRD42022377820).FindingsWe included 45 studies. Self-isolation was inconsistently defined. Only four studies did not use self-report to measure adherence. Of 41 studies using self-report measures, only one reported reliability; another gave indirect evidence for a lack of validity of the measure. Rates of adherence to self-isolation ranged from 0% to 100%. There was little evidence that self-isolation adherence was associated with socio-demographic or psychological factors.InterpretationThere was no consensus in defining, operationalising, or measuring self-isolation. Only one study presented evidence of the psychometric properties of the measure highlighting the significant risk of bias in included studies. This, and the dearth of scientifically rigorous studies evaluating the effectiveness of interventions to increase self-isolation adherence, is a fundamental gap in the literature.FundingThis study was funded by Research England Policy Support Fund 2022-23; authors were supported by the NIHR Health Protection Research Unit in Emergency Preparedness and Response.
Environmentally sustainable food: an analysis of consumer practices and their diffusion in France
Authors: Innocent Morgane , Francois Lecompte Agnes , Guillemot Samuel , Divard Ronan 
Published: September 2023

PurposeThis aim of this study is to identify the ways of helping public authorities bring about change to environmentally sustainable household food practices.Design/methodology/approachThe authors identified the practices involved in this concept from the consumer perspective and measured their diffusion among French households. The analyses were conducted following two successive data collection campaigns comprising 571 and 501 respondents in France. The methodology involved two complementary scaling techniques: factor analysis and item response theory.FindingsThe results show that consumers understand sustainable food through five food practices: buying and cooking products with sustainable attributes, anti-waste storage, self-production, plant protein consumption and anti-waste cooking.Originality/valueThe findings suggest that while at the individual level people appear to have incorporated anti-waste practices into their daily lives, at the household level, there is still work to be done for improving diets and stimulating the production of home-grown food. It is also worth noting that the emerging vision typically involves sustainable foods that are organic, locally grown, seasonal, based on fair trade and packaging-free.
Comparative tribological performance of a-C:H, ta-C and AlCrSiN coatings on 20CrMnTi gear steel under dry sliding condition
Authors: Lei Zonglin , Li Zunge , Xiao Yangyi 
Published: September 2023

Purpose
This study aims to investigate the surface modification on 20CrMnTi gear steel individually treated by diamond-like carbon films and nitride coatings.

Design/methodology/approach
For this purpose, the mechanical properties of a-C:H, ta-C and AlCrSiN coatings are characterized by nano-indentation and scratch tests. The friction and wear behaviors of these three coatings are evaluated by ball-on-disc tribological experiments under dry contact conditions.

Findings
The results show that the a-C:H coating has the highest coating-substrate adhesion strength (495 mN) and the smoothest surface (Ra is about 0.045 µm) compared with the other two coatings. The AlCrSiN coating shows the highest mean coefficient of friction (COF), whereas the ta-C coating exhibits the lowest one (steady at about 0.16). The carbon-based coatings possess excellent self-lubricating properties compared with nitride ceramic ones, which effectively reduce the COF by about 64%. The major failure mode of carbon-based coatings in dry contact is slight abrasive wear. The damage of AlCrSiN coating is mainly adhesive wear and abrasive wear.

Originality/value
It is suggested that the carbon-based film can effectively improve the friction-reducing and wear resistance performance of the gear steel surface, which has a promising application prospect in the mechanical transmission field.

Authors: Al-Daihani Meshari , Dirie Khadar Ahmed , Alam Md. Mahmudul , Abdullah Ahmad Sufian 
Published: September 2023

Purpose
Cash waqf is a powerful financial instrument that deals with the issue of liquidity constraints in waqf institutions. While there are several models of cash waqf operating in different countries, there is increasing demand for innovative cash waqf models, especially within the financial technology context. This paper aims to propose a practical alternative model of funding for waqf institutions using the concepts of crowdfunding and cash waqf.

Design/methodology/approach
This study evaluated the literature relevant to cash waqf models that have been implemented in different countries and proposed a new viable alternative model.

Findings
Results offer an alternative financing model, named crowdfunding cash waqf model, for waqf institutions to overcome monetary constraints and enable development projects to be completed.

Practical implications
The current study has important implications for both officials and relevant stakeholders. It is sought to bring better consistency between cash waqf donors, solving the liquidity problem faced by waqf institutions, enhancing the transparency of waqf institutions and their use of waqf funds, wealth circulation and financing businesses without interest-based loans (riba). By incorporating a crowdfunding and investment mechanism in the model, this method of collecting funds will assist governments in reducing their expenditure on waqf institutions and other social development programmes.

Originality/value
The proposed model differs from current methods of generating cash waqf, including those are also internet-based. The proposed model is devised to help waqf institutions achieve financial sustainability by including an investment mechanism in the model to sustain the development of waqf projects.
Transformation leadership's emotional labor and follower's psychological capital: mediating effect of emotional contagion
Authors: Kashive Neerja , Raina Bhavna 
Published: September 2023

PurposeThe study aims to closely look at the phenomenon of transformational leadership and the psychological capital of followers by using affective process theory (APT). It has empirically tested the mediation of the perceived emotional labor (EL) of a leader and susceptible emotional contagion (EC) of followers when studying the effect of transformational leadership on the psychological capital (PsyCap) of followers.Design/methodology/approachThe method adopted was mixed methodology. The data were collected from the 120 respondents and their perception regarding the construct as identified by previous literature was captured through a structured questionnaire. The relationships and hypotheses were tested by the structural equation modeling (SEM) model using SMART PLS. Further 20 semi-structured interviews were conducted using a qualitative approach.FindingsThe current research has empirically shown how specific aspects of transformational leadership, i.e. individual consideration perceived by followers also show high use of perceived deep acting strategy. Deep acting EL strategy is impacting positive EC and positive EC is leading to higher PsyCap of followers generating more work efficacy, hope, optimism and resilience. Mediation of positive EC between Deep acting EL and PsyCap was also observed. In qualitative studies done with the participants, major themes that emerged were transformational leadership, EL strategies, EC and PsyCap.Practical implicationsIn times of uncertainty and stress after the post-COVID scenario, employees are facing emotional burnout due to increased work pressure and workload. Transformational leadership has become very critical to manage the PsyCap of followers by using correct EL strategies. Leaders can focus on the optimism and resilience aspect of PsyCap.Originality/valueThe current research has taken affective process theory (APT) as a foundation to understand the connection between transformational leadership and the PsyCap of followers. The study has specifically picked up the fourth mechanism of affective linkage as suggested by Elfenbein (2014) called emotional recognition and seen how emotions are transferred from source (leaders) to recipient (followers). The research has contributed by empirically testing the mediation of the perceived EL of leaders and the susceptible EC of followers and how they affect the PsyCap of followers.

Authors: Muniz Jr. Jorge , Ramalho Martins Fernando , Wintersberger Daniel , Oliveira Santos João Paulo 
Published: September 2023

Purpose
This paper aims to discuss how trade union leaders deal with the implementation of Industry 4.0 (I4.0). The study is circumscribed to the Brazilian automotive sector and came from a human-centric (Industry 5.0) concern related to issues such as organisational learning, knowledge, innovation and workplace learning.

Design/methodology/approach
Case studies in two truck plants related to union participation during new product and process implementation based on Industry 4.0. Semi-structured interviews with union leaders from both plants were conducted to determine the subtle similarities and differences between the two polar types.

Findings
The findings pointed out that human resources and workplace learning must be reviewed to prepare workers to face I4.0. Four themes are explored: modernisation origins; negotiation process; workers’ concerns; and results and lessons learned. The findings highlight concerns about employees and job loss; replacement of workers by technological devices; workplace learning and the trade union perspective; and influence of the country’s economic situation on I4.0 implementation in social systems dependent on worker tacit knowledge.

Originality/value
This paper presents labour union leaders’ perspectives related to the impact of I4.0 and contributes to a better understanding of industry-worker workplace learning.

Authors: Lu Junjian , Zhong Hongbin , Luo Fei 
Published: September 2023

Purpose
The purpose of this research is as follows: DPP-BOH-PVA has been synthesized from 1,1′:3′,1″-terphenyl-5'-boronic acid (DPP-OH) and polyvinyl alcohol (PVA). The afterglow lifetime of DPP-BOH-PVA was studied by changing contents of DPP-OH (1, 2 and 4 Wt.%). These films were characterized with Fourier transform infrared, X-ray diffraction as structural analysis and DSC as thermal analysis. Afterglow lifetimes were evaluated as time-resolved emission decay profile analysis. Fiber films of DPP-BOH-PVA-2-E have been prepared by electrospinning method with the diameter of 5 μm and afterglow life time of 2.1 s (@ 535 nm) under ambient conditions. Stimulus responsive properties with afterglow emission for fiber film were investigated.

Design/methodology/approach
During the synthesis of the polymer, modification was carried out using DPP-OH/PVA with a molar ratio of 1/4, under an alkalinity medium with ammonium hydroxide and with a temperature of 80°C.

Findings
XRD results indicate that DPP-BOH-PVA film had high crystallinity, which is crucial for preparing organic room temperature phosphorescence (RTP) materials.

Research limitations/implications
The reaction mixture must be stirred continuously. Temperature should be controlled to prevent the rapid evaporation of ammonium hydroxide.

Practical implications
This study provides technical information for the synthesis of multidimensional stimulation response RTP micron fiber thin film. The electrospinning technology may also promote the applications of the large areas of RTP films.

Social implications
This resin will be used for the multidimensional stimulation response RTP fiber thin film.

Originality/value
The diameter of fiber film of PP-BOH-PVA-2-E by electrospinning method was in the range of 5 μm, and its afterglow lifetime decayed to be 2.1 s.
Identifying critical success factors of total quality management via comprehensive assessment of soft and hard factors
Authors: Chen Jih Kuang 
Published: September 2023

PurposeEffective total quality management (TQM) practices rely on the accurate classification of critical success factors (CSFs). The impact matrix cross-reference multiplication technique for classification (MICMAC) or/and fuzzy MICMAC (FMICMAC) can be used to identify key factors in the complex set. However, TQM includes both “hard” and “soft” factors, limiting application of the traditional MICMAC/FMICMAC method.Design/methodology/approachPrevious literature on TQM was reviewed, CSFs were identified, and factors were sorted into soft and hard categories. The combined fuzzy integration and dual-aspect MICMAC (fuzzy dual-aspect MICMAC approach) was then applied to identify, cluster and prioritize the CSFs of TQM.FindingsA total of 20 factors (10 soft and 10 hard) were identified and isolated to assess the manufacturing- and service-related TQM practices of the Pearl River Delta Region of China. Seven driver factors and one linkage factor emerged as the key CSFs that managers should prioritize.Research limitations/implicationsA major limitation of this study is the dependency of the results on the definitions of linguistic labels. If the linguistic definitions of TQM CSFs do not closely correspond to the expert opinion data, then the analysis results may be inaccurate. Additionally, although expert opinions are utilized in the proposed method for comprehensive assessments, these opinions may influence the final results due to their inherent subjectivity.Originality/valueA novel fuzzy dual-aspect MICMAC approach was developed to identify and classify CSFs for optimal TQM practices. This approach allows clustering of CSFs so that decision-makers can prioritize factors according to their dependence and driving powers. Practitioners should concentrate on the CSFs with higher driving powers for successful TQM.

José Martí and Antonio Gramsci: The World as a Radical Geography
Authors: Vegliò Simone 
Published: September 2023

AbstractThis paper lays the ground for a novel discussion on the encounter between José Martí and Antonio Gramsci. It argues that Martí and Gramsci can be profitably and innovatively read together when interrogating the profound “spatial articulations” that animate their political vision. The discussion principally focuses on Martí's concept of Our America and Gramsci's Southern Question. Methodologically, the article deploys a “diachronic tactic” that mobilises a broad body of literature that emerged long after Martí's and Gramsci's lives, particularly considering contributions within Radical Geography and Postcolonial Studies.
