Tailored Photoacoustic Apertures with Superimposed Optical Holograms
Authors: Howe Glenn A. , Tang Meng-Xing , Rowlands Christopher J. 
Published: August 2023

AbstractA new method of generating potentially arbitrary photoacoustic wavefronts with optical holograms is presented. This method uses nanosecond laser pulses at 1064 nm that are split into four time-delayed components by means of a configurable multipass optical delay apparatus which serves to map the pulses onto phase-delayed regions of a given acoustic wavefront. A single spatial light modulator generates separate holograms for each component which are imaged onto a photoacoustic transducer comprised of a thermoelastic polymer. The spatially- and temporally-modulated holograms facilitate a phased array effect which enables beam steering of the resulting acoustic pulse. For a first experimental demonstration of the method, as verified by simulation, an acoustic beam is steered in four directions by around 5 degrees.

AbstractResearch indicates a connection between frontal brain activity asymmetry and self-regulation, particularly, approach and inhibitory tendencies. However, the underlying brain mechanism remains unclear. Our preregistered study used transcranial direct current stimulation (tDCS) to overcome limitations in prior correlational studies, investigating the link between frontal alpha asymmetry (FAA), a potential neuromarker and a treatment target for relevant psychiatric disorders, and the behavioral and brain activity components related to approach and avoidance tendencies, as observed in a visuospatial cueing (VSC) paradigm. We utilized a randomized sham-controlled design with 65 healthy participants. Participants’ resting-state EEG was recorded to calculate FAA scores before and after 2 mA anodal tDCS to the right frontal site. They also completed a VSC task with neutral and intrinsic reward-associated (food) conditions. Results indicated no impact of tDCS on FAA or behavioral attentional bias/disengagement. Surprisingly, secondary analyses revealed tDCS enhancing attentional bias for rewards, as seen in enhanced Late Directing Attention Positivity and P1 effect. However, these effects did not translate into observable behavioral changes. The observed effects are consistent with a noradrenergic mechanism rather than asymmetry of brain activity.
Robust spatial self-organization in crowds of asynchronous pedestrians

AbstractSimilar to other animal groups, human crowds exhibit a variety of self-organized collective behaviors. Spontaneous formation of unidirectional lanes in bidirectional pedestrian flows is one of the most striking examples of self-organization in human crowds. In addition, previous experimental studies have suggested that stepping among pedestrians is spontaneously synchronized over time. However, those studies have primarily focused on one-dimensional, single-file crowds, limiting our understanding of temporal stepping patterns in crowds with more freedom of movement and their relationship to spatial patterns of organization. Here, we conducted experiments of bidirectional pedestrian flows (24 pedestrians in each group) and investigated the relationship between collective footsteps and self-organized lane formation by tracking each individual trajectory as well as foot-stepping kinematics. We found that, unlike previous studies, pedestrians did not spontaneously align their steps unless there was an external auditory cue to follow. Moreover, we found that footstep synchronization generated by external cues disturbed the flexibility of pedestrians’ lateral movements, increased potential collision risks, and narrowed the formed lanes, suggesting structural instability in the spatial organization. These results imply that, without external cues, pedestrians marching out of step with each other can efficiently self-organize into robust structures. Understanding how asynchronous individuals contribute to ordered collective behavior has potential applications for promoting efficient crowd management and will inform theoretical models for human and other animal collective behavior with asynchronous positional updates.
Evaluation of ownership structure and audit-quality in the wake of the Covid-19 crisis: empirical evidence from Jordan
Authors: Alharasis Esraa Esam 
Published: August 2023

Purpose
This study aims to collect new empirical evidence to determine how different forms of ownership structure responded to the recent COVID-19 crisis. In light of this tragedy, it explores the relationship between ownership structure forms (i.e. block-holders, foreign, institutional and family ownerships) and audit quality (proxied by audit fees).

Design/methodology/approach
In total, 3,200 firm-year observations for Jordanian enterprises covering the years 2005 through 2020 are used in an ordinary least squares regression with firm-clustered standard error to assess the hypotheses.

Findings
The regression results showed that COVID-19 strengthens the association between each type of ownership (i.e. block-holders, foreign, institutional ownership forms) and audit quality. This result reflects the need for high-quality audit services during the pandemic by such owners to improve their business decisions and limit agency-conflict issues. However, the analysis failed to find any effect of COVID-19 when it comes to family ownership. Family-controlled firms may react faster in crisis situations, and correspondingly, they do not bear high audit costs. The extended analysis covering the years 2005–2022 came to the same results.

Practical implications
The results aid authorities in their control and management of the auditing business. The findings have important consequences for policymakers, lawmakers, regulators and the audit profession as they assess the growing issues in an uncertain economic environment. Evidence is provided that may be used to reassure investors and aid authorities as they devise appropriate remedies to the pandemic-triggered economic crisis. The findings may aid in the improvement of legislation that governs Jordan’s auditing industry. Furthermore, the results can be generalized to other Middle Eastern countries.

Originality/value
To the best of the authors’ knowledge, this is the first study to empirically evaluate how different types of ownership affect audit quality in response to a dramatic shift in auditors’ working conditions brought on by the global health calamity. In emerging economies like Jordan, this type of analysis allows for preliminary assumptions to be established about ownership status during the COVID-19 outbreak. It adds to the body of auditing knowledge by shedding light on how various kinds of ownership affect responses to adverse events. This assessment is intended to serve as the definitive testimony in the field of accounting regarding the effects of the coronavirus across various corporations’ portfolios.
Supply network resilience capabilities: a social–ecological perspective
Authors: Statsenko Larissa , Jayasinghe Ruchini Senarath , Soosay Claudine 
Published: August 2023

Purpose
This study aims to investigate supply network (SN) resilience capabilities across the organizational, supply chain (SC) and industry levels by drawing on the complex adaptive systems (CASs) theory and the social–ecological perspective of resilience. An empirically grounded framework operationalizes the concept of social–ecological resilience by expounding resilience capabilities across phases of the CAS adaptive cycle.

Design/methodology/approach
This research uses a qualitative multiple case study approach. It draws on the case of the Australian Defence Manufacturing SN (ADM SN) during COVID-19 disruptions. A total of 28 interviews with senior decision makers from 17 companies, complemented by 5 interviews with the Australian Defence SC organizations and secondary data analysis, support the findings.

Findings
Individual organizations’ SC visibility and flexibility enabled by effective risk management and collaboration enhance the ability of the SN to anticipate and prepare for disruption. At the same time, the strength of SC relationships reduces resilience. SN disruption response velocity is enabled by inventory redundancy, process flexibility at the organizational level and visibility and collaboration at the SC level. Institutional support at the national industry level, development of value-adding capabilities and manufacturing process flexibility at the organizational level enhances the SN’s ability to re-organize. The transition from hierarchical to decentralized collaborative governance enhances SN resilience.

Practical implications
From a practitioner’s perspective, the findings highlight the need to embrace a broader view of SC beyond immediate tiers. Decision-makers in multinational companies must recognize the long-term impact of their procurement decisions on the supplier ecosystem. Developing local supplier capabilities rather than relying on established global SCs will pay off with future resilience. It, however, demands substantial investment and radical changes across all SC tiers. The lesson for smaller firms is not to over-rely on the existing relationships with supply partners. Although trust-based relationships and collaboration are essential, over-commitment can be counterproductive during global disruptions. With a lack of visibility and control over the SC, operational flexibility is critical for small firms to adapt to shifts in supply and demand.

Originality/value
To the best of the authors’ knowledge, this empirical research is one of the first attempts to operationalize the social–ecological perspective of SN resilience. Evidence-based theoretical propositions contribute to the emerging conversation about the CAS nature of resilience by demonstrating the multi-level effects of resilience capabilities.

Authors: Agyeiwaah Elizabeth , Bangwayo-Skeete Prosper , Opoku Emmanuel Kwame 
Published: August 2023

Purpose
Building on the social exchange theory, this study aims to investigate the impact of perceived workgroup inclusion on migrant subjective well-being, organization identification and organizational citizenship behavior (OCB).

Design/methodology/approach
Structural equation modeling was applied to 440 surveyed migrant workers in Macau’s tourism and hospitality industry.

Findings
Perceived workgroup inclusion has a positive influence on migrant workers’ subjective well-being and organizational identification, which both in turn positively affect their OCBs.

Originality/value
Based on the social exchange theory, this study formulates a model that explains how migrant workers' inclusion impacts their well-being, identification and organizational behaviors. It provides theoretical and practical insights into how migrant workers’ inclusion could serve as a talent management strategy that promotes OCBs.
Alterations of SIRT1/SIRT3 subcellular distribution in aging undermine cardiometabolic homeostasis during ischemia and reperfusion

Published: August 2023

AbstractAge‐related sensors Sirtuin1 (SIRT1) and Sirtuin3 (SIRT3) play an essential role in the protective response upon myocardial ischemia and/or reperfusion (I/R). However, the subcellular localization and co‐regulatory network between cardiac SIRT1 and SIRT3 remain unknown, especially their effects on age‐related metabolic regulation during acute ischemia and I/R. Here, we found that defects of cardiac SIRT1 or SIRT3 with aging result in an exacerbated cardiac physiological structural and functional deterioration after acute ischemic stress and failed recovery through reperfusion operation. In aged hearts, SIRT1 translocated into mitochondria and recruited more mitochondria SIRT3 to enhance their interaction during acute ischemia, acting as adaptive protection for the aging hearts from further mitochondria dysfunction. Subsequently, SIRT3‐targeted proteomics revealed that SIRT1 plays a crucial role in maintaining mitochondrial integrity through SIRT3‐mediated substrate metabolism during acute ischemic and I/R stress. Although the loss of SIRT1/SIRT3 led to a compromised PGC‐1α/PPARα‐mediated transcriptional control of fatty acid oxidation in response to acute ischemia and I/R, their crosstalk in mitochondria plays a more important role in the aging heart during acute ischemia. However, the increased mitochondria SIRT1‐SIRT3 interaction promoted adaptive protection to aging‐related fatty acid metabolic disorder via deacetylation of long‐chain acyl CoA dehydrogenase (LCAD) during ischemic insults. Therefore, the dynamic network of SIRT1/SIRT3 acts as a mediator that regulates adaptive metabolic response to improve the tolerance of aged hearts to ischemic insults, which will facilitate investigation into the role of SIRT1/SIRT3 in age‐related ischemic heart disease.
Drawing African Diasporic women anthropologists in dialogue: Decolonizing the canon
Authors: Johnson Amanda Walker 
Published: August 2023

AbstractInspired by the use of naming and portraiture together in the Black artivism–such as that protesting the murders of George Floyd and Breonna Taylor–this paper reflects on the use of portrait drawing as a practice of genealogy. While working on a project to raise the visibility of scholars and their works in the African Diaspora, specifically Francophone women anthropologists, I felt compelled to draw their portraits. Drawing African Diasporic women into dialogue from the archive attends to temporality, vision, and listening, elements centered within anthropological practice, but also implicated in the attachment of the discipline to colonial logics, particularly of allochronism, objectification and silencing. The multisensory, embodied and slow practice of drawing alongside reading scholars' works allows for diasporic time‐travel, shifting the gaze, and constructing a decolonizing “listening genre”.

Published: August 2023

AimsFinger‐prick sampling has emerged as an attractive tool for therapeutic drug monitoring and associated diagnostics. We aimed to validate the clinical performance of using two volumetric devices (Capitainer® qDBS and Mitra®) for monitoring tacrolimus, creatinine and haemoglobin in kidney transplant (KTx) recipients. Secondarily, we evaluated potential differences between finger‐prick sampling performed by healthcare professionals vs. self‐sampling, and differences between the two devices.MethodsWe compared finger‐prick and venous sampling in three settings: microsampling performed by healthcare personnel, self‐sampling under supervision, unsupervised self‐sampling. The finger‐prick samples were analysed with adapted methods and results compared to routine method analysis of the venous blood samples.ResultsTwenty‐five KTx recipients completed the main study and 12 KTx recipients completed a post hoc validation study. For tacrolimus measurements and predicted area under the curve, the proportions within ±20% difference were 79%–96% for Capitainer and 77%–95% for Mitra. For creatinine and haemoglobin, the proportions within ±15% were 92%–100% and 93%–100% for Capitainer and 79%–96% and 67%–92% for Mitra, respectively. Comparing sampling situations, the success rate was consistent for Capitainer (92%–96%), whereas Mitra showed 72%–88% and 52%–72% success rates with samples collected by healthcare personnel and the patients themselves.ConclusionsCapitainer and Mitra are technically feasible for measuring tacrolimus, creatinine and haemoglobin. In the context of self‐sampling, Capitainer maintained consistent sampling success and analytical quality. Implementing volumetric finger‐prick self‐sampling for the monitoring of tacrolimus, creatinine and haemoglobin may simplify and improve the follow‐up of KTx recipients.

AbstractObjectivesWe aimed to identify psychological factors associated with the use of facemasks in shops in England following removal of legal requirements to do so, and to compare associations with and without legal restrictions.DesignRepeated cross‐sectional online surveys (n ≈ 2000 adults) between August 2020 and April 2022 (68,716 responses from 45,682 participants) using quota sampling.MethodsThe outcome measure was whether those who had visited a shop for essentials in the previous seven days reported always having worn a facemask versus sometimes or not at all. Psychological predictor variables included worry, perceived risk and severity of COVID‐19 and the perceived effectiveness of facemasks. Socio‐demographic variables and measures of clinical vulnerability were also measured. For the period following removal of legal restrictions, multivariable regression was used to assess associations between the primary outcome variable and predictors adjusting for socio‐demographic and clinical vulnerability measures. The analysis was repeated including interactions between psychological predictors and presence versus absence of legal restrictions.ResultsWorry about COVID‐19, beliefs about risks and severity of COVID‐19 and effectiveness of facemasks were substantially and independently associated with the use of facemasks. Removal of legal obligations to wear facemasks was associated with a 25% decrease in wearing facemasks and stronger associations between psychological predictors and wearing facemasks.ConclusionsLegal obligations increase rates of wearing a facemask. Psychological factors associated with wearing a facemask could be targets for interventions aiming to alter rates of wearing a facemask. These interventions may be more effective when there are no legal obligations to wear a face covering in place.
Auction design by an informed seller: A foundation of reserve price signalling
Authors: Zhao Xin 
Published: August 2023

AbstractThis paper studies mechanism design by a seller privately informed of the (continuous) quality of an indivisible object. An important solution to this informed‐principal problem, the Rothschild–Stiglitz–Wilson mechanisms, which correspond to the least‐cost separating allocations in the signalling literature, is characterized. The characterization reveals that reserve prices are the least costly device to separate sellers of different qualities: In the RSW mechanisms, the lowest‐quality seller adopts her public‐information optimal selling procedure, and each higher‐quality seller adopts a selling procedure that differs from her public‐information optimal one only in that the reserve prices are higher. This finding provides a mechanism‐design foundation for reserve‐price signalling studied in the literature.
When confessing sin feels good
Authors: Graff‐Kallevåg Kristin , Kaufman Tone Stangeland 
Published: August 2023

AbstractThis paper draws on a qualitative study of how young people engaged in two youth ministries in the Church of Norway reflect on sin and shame in relation to their existential dilemmas . The authors analyze this practice through the lens of Hartmut Rosa's concept of resonance, arguing that there is consonance between how young people in the study express shame and the Lutheran understanding of sin as being curved in on oneself. Both sin and shame prevent the subject from being open to the world, thus constituting resistance to resonance. Yet, the practice of confessing sin may be a remedy to this closing in on oneself, as confession affords a resonant space, countering feelings of existential inadequacy caused by both sin and shame.Bringing the concept of vulnerability into the discussion, the paper further argues that confessing sin may prove healing and liberating also for experiences of shame as long as it does not violate the subject's ability to speak with her own voice or involve harmful god‐images or harmful power dynamics.
D2 dopamine receptor‐mediated mechanisms of dopaminergic system modulation in in vivo and in vitro experimental models of migraine
Authors: Baranoglu Kilinc Yasemin , Torun Ibrahim Ethem , Kilinc Erkan 
Published: August 2023

AbstractThe dopaminergic system is implicated in the pathophysiology of migraine. However, the underlying mechanisms remain unclear. We explored the effects and mechanisms of dopaminergic system modulation in the in vivo and in vitro rat models of migraine. Dopaminergic agonist apomorphine, D2 receptor antagonists metoclopramide and haloperidol and 5‐HT3 receptor antagonist ondansetron alone and together were tested in nitroglycerin‐induced migraine model, in vivo. Likewise, the combinations of drugs were also tested on basal calcitonin gene‐related peptide (CGRP) release in vitro hemiskull preparations. Mechanical allodynia was tested by von Frey filaments. CGRP concentrations in trigeminovascular structures and in vitro superfusates and c‐Fos levels in the brainstem were determined by enzyme‐linked immunosorbent assay. Meningeal mast cells were evaluated with toluidine blue staining. Apomorphine further enhanced nitroglycerin‐induced mechanical allodynia, brainstem c‐fos expression, trigeminal ganglion and brainstem CGRP concentrations and meningeal mast cell degranulation, in vivo. Haloperidol completely antagonised all apomorphine‐induced effects and also alleviated changes induced by nitroglycerin without apomorphine. Metoclopramide and ondansetron partially attenuated apomorphine‐ or nitroglycerin‐induced effects. A combination of haloperidol and ondansetron decreased basal CGRP release, in vitro, whereas the other administrations were ineffective. Apomorphine‐mediated dopaminergic activation exacerbated nitroglycerin‐stimulated nociceptive reactions by further enhancing c‐fos expression, CGRP release and mast cell degranulation in strategical structures associated with migraine pain. Metoclopramide partially attenuated the effects of apomorphine, most likely because it is also a 5‐HT3 receptor antagonist. Haloperidol with pure D2 receptor antagonism feature appears to be more effective than metoclopramide in reducing migraine‐related parameters in dopaminergic activation‐ and/or NTG‐induced migraine‐like conditions.
