The influence of familiarity on the neural coding of face sex
Authors: Foster Celia , Schultz Johannes , Munzing Melissa , Bülthoff Isabelle , Armann Regine 
Published: October 2022

AbstractIn behaviour, humans have been shown to represent the sex of faces categorically when the faces are familiar to them. This leads to them judging faces crossing the category boundary (i.e. from male to female) as more different than faces that are within the same category. In this study, we investigated how faces of different sexes are encoded in the brain, and how familiarity changes the neural coding of sex. We recorded participants’ brain activity using fMRI while they viewed both familiar and unfamiliar faces that were morphed in their sex characteristics (i.e. between male and female). Participants viewed pairs of faces that were either identical, or differed in their sex morph level, with or without a categorical change in perceived sex (i.e. crossing the perceived male/female category boundary). This allowed us to disentangle physical and categorical neural coding of face sex, and to investigate if neural coding of face categories was enhanced by face familiarity. Our results show that the sex of familiar, but not unfamiliar, faces was encoded categorically in the medial prefrontal and orbitofrontal cortex as well as in the right intraparietal sulcus. In contrast, the fusiform face area showed a sensitivity to the physical changes in the sex of faces that was unaffected by face familiarity. The occipital face area showed its highest responses to faces towards the ends of the sex morph continuum (i.e. the most male or most female faces), and these responses were also unaffected by face familiarity. These results suggest that there is a dissociation between the brain regions encoding physical and categorical representations of face sex, with occipital and fusiform face regions encoding physical face sex properties and frontal and parietal regions encoding high-level categorical face sex representations that are linked to face identity.

Published: October 2022

SUMMARYNeuronal activity during experience is thought to induce plastic changes within the hippocampal network which underlie memory formation, although the extent and details of such changesin vivoremain unclear. Here, we employed a temporally precise marker of neuronal activity, CaMPARI2, to label active CA1 hippocampal neuronsin vivo, followed by immediate acute slice preparation and electrophysiological quantification of synaptic properties. Recently active neurons in the superficial sublayer ofstratum pyramidaledisplayed larger post-synaptic responses at excitatory synapses from area CA3, with no change in pre-synaptic release probability. In contrast,in vivoactivity weakened both pre- and post-synaptic excitatory weights onto pyramidal cells in the deep sublayer.In vivoactivity of deep and superficial neurons within sharp-wave ripples was bidirectionally changed across experience, consistent with the observed changes in synaptic weights. These findings reveal novel, fundamental mechanisms through which the hippocampal network is modified by experience to store information.
Differential retention of Pfam domains creates long-term evolutionary trends
Authors: James Jennifer , Nelson Paul , Masel Joanna 
Published: October 2022

AbstractProtein domains that emerged more recently in evolution have higher structural disorder and greater clustering of hydrophobic residues along the primary sequence. It is hard to explain how selection acting via descent with modification could act so slowly as not to saturate over the extraordinarily long timescales over which these trends persist. Here we hypothesize that the trends were created by a higher level of selection that differentially affects the retention probabilities of protein domains with different properties. This hypothesis predicts that loss rates should depend on disorder and clustering trait values. To test this, we inferred loss rates via maximum likelihood for animal Pfam domains, after first performing a set of stringent quality control methods to reduce annotation errors. Intermediate trait values, matching those of ancient domains, are associated with the lowest loss rates, making our results difficult to explain with reference to previously described homology detection biases. Simulations confirm that effect sizes are of the right magnitude to produce the observed long-term trends. Our results support the hypothesis that differential domain loss slowly weeds out those protein domains that have non-optimal levels of disorder and clustering. The same preferences also shape differential diversification of Pfam domains, further impacting proteome composition.
Shadow economy in Palestinian territories using currency demand approach
Authors: Abuamsha Mohammad Kamal , Shumali S. 
Published: October 2022

PurposeThe study aims at estimating the shadow economy (SE) using the method of demand for currency in Palestine for the period 2008–2018 by studying the relationship between a group of variables that affect the ratio of money traded outside the banking system to the money supply in the broad sense.Design/methodology/approachThe study has adopted analytical and descriptive research methods to estimate SE in Palestinian territories. The data has been obtained from the inflation reports issued by the Palestinian Monetary Authority for ten years, from 2008 to 2018. A standard model was constructed using EViews version 8 for statistical data processing after converting the annual data to quarterly data.FindingsThe authors demonstrated that the size of the SE in Palestinian territories has varied over time, and the annual average of its size during the study period reached about $1764.893 (in millions). This amount constitutes about 15.5% of the gross domestic product. The study provides recommendations for reducing the size of the SE in Palestinian territories.Practical implicationsThe current study shows that shadow economics could significantly matter for economic policy design by policymakers.Originality/valueThis study deals directly with Tanzi’s “estimation of shadow economy in Palestinian territories” concept and its impact on economic policies.
The macroeconomic impacts of the mobile money: empirical evidence from EVC plus in Somalia
Authors: Mohamed Abdinur Ali , Nor Mohamed Ibrahim 
Published: October 2022

Purpose
The purpose of this study was to examine the macroeconomic impact of mobile money in Somalia using quarterly data from 2010 to 2020.

Design/methodology/approach
This study applied the structural vector autoregressive approach to examine the response of the macroeconomic variables to the mobile money shocks.

Findings
The results show that mobile money increases consumer spending by reducing transaction costs and enhancing access to finance, which promotes the expansion of aggregate output. This study also finds that mobile money helps exchange rate stability and price level maintenance, boosting trade openness. Moreover, mobile money is linked to the rise in real income due to productivity improvement and price stability. The results of this study indicated that mobile money has a short-run relationship with aggregate output, household consumption, price level, trade openness and real income. Through the Granger causality test, this study finds that mobile money has a unidirectional relationship with the exchange rate, price level, household consumption and trade openness.

Originality/value
The empirical findings of this study imply that mobile money can create a wide range of financial services to improve the financial system in rural and urban areas; hence, it enables poor and rural members of society to make payments and receive-and-transfer money using their mobiles.
Mapping of Islamic corporate governance research: a bibliometric analysis
Authors: Pahlevi Reza Widhar 
Published: October 2022

Purpose
The principles of good corporate governance (GCG) in Islam are more stakeholder oriented than shareholder oriented. If the implementation of GCG always refers to the principles of GCG that are sourced from the values of capitalism, it is necessary to reconstruct corporate governance so that it can be applied to Sharia institutions. Therefore, this study aims to carry out a detailed development of Islamic corporate governance with careful evaluation of the various aspects of the scientific panorama inherent in Islamic business and social finance.

Design/methodology/approach
The approach in this research is Islamic corporate governance research as a reference in “Article Title, Abstract and Keywords” based on Scopus from 1994 to 2021. The analysis was carried out in December 2021. VOSviewer and Excel software were used to analyze the collected data and apply bibliometric analysis.

Findings
The research findings indicate that Islamic corporate governance research can be categorized into subfields, such as research on the basics of Islamic corporate governance, analysis of Islamic corporate governance and research on various applications of Islamic corporate governance in Islamic finance. Although there is some important or fundamental research in Islamic corporate governance, this does not yet answer for such a powerful Islamic financial instrument. This study relies on research in the existing Islamic corporate governance literature and future research.

Research limitations/implications
This study relies on research in the existing Islamic corporate governance literature and future research. The outcome of the current study will provide a strategic perspective to law-making bodies and practitioners of the organization to implement Islamic corporate governance to attain a higher sustainability performance.

Practical implications
GCG practices make companies have better performance; the failure of small and medium enterprises is the result of weak corporate governance practices. Corporate governance is indeed not a solution to all the problems faced, but governance is an unquestionable thing to achieve business success.

Social implications
It discusses above the current state of corporate governance practices in the conventional economy and establishes the measurement of GCG at the functional level, compared from Islamic perspectives. Like any other civilization and religion, Islamic culture also embedded GCG since the early days of Islamization.

Originality/value
To the best of the authors’ knowledge, this paper is the first to examine the existing Islamic corporate governance literature by bibliometric analysis. The definite results and research areas can help scholars and researchers to conduct future research to enhance the scientific development of Islamic finance and provide alternative instruments to implement corporate governance according to Islamic values.
Manufacturer's servitization level and financial performance: the role of risk management
Authors: Jat Mohsin Nasir , Jajja Muhammad Shakeel Sadiq , Shah Syed Aamir Ali , Farooq Sami 
Published: October 2022

PurposeThe objective of this research is to investigate the impact of offering product-linked services on the effectiveness of risk management and, subsequently, on financial performance.Design/methodology/approachThe investigation is based on an empirical analysis employing structural equation modeling (SEM) and cross-industry and multi-country survey data of 307 companies. The theorization is guided by the information processing theory (IPT).FindingsConsidering the basic and advanced classification of services, the analysis suggests that only the provision of advanced services influences the effectiveness of risk management. Specifically, the provision of advanced services strengthens the preventive dimension of risk management. Surprisingly, the analysis reveals a negative direct impact of preventive risk management on financial performance. Preventive risk management, however, indirectly enhances financial performance by supporting reactive risk management.Practical implicationsFor practitioners, the research suggests a positive impact of servitization in a long term rather than in form of instant financial benefits. The research attempts to highlight the specific role of supply chain risk management (SCRM) through which servitization has a positive impact on financial performance.Originality/valueAlthough there are assumptions about both reduction and increase in risk when manufacturers offer services, the extant literature lacks an empirical investigation on the association between servitization and the effectiveness of risk management. This study addresses the stated gap and offers novel insights into the role of SCRM in the performance consequences of servitization.
Virtual campuses in developing countries: an evaluation of the “right connectors” for effective e-learning in higher education institutions in Zimbabwe
Authors: Nyathi Musa 
Published: October 2022

PurposeThe purpose of this paper is to evaluate the relative effects of three facets or connectors argued to be vital for learners in successful e-learning outcomes in developing economies.Design/methodology/approachData were collected through a survey involving 130 learners. A stratified sampling technique was employed. Regression analyses making use of linear, multiple and PROCESS macro in Statistical Package for the Social Sciences (SPSS) were used to analyze data.FindingsTechnological self-efficacy and social presence are the most important facets needed by participants for effective learning in higher education institutions in developing countries. Learning tools meant to enhance teaching and learning and also contribute to learner satisfaction.Practical implicationsThe findings of the study provide insights to academic administrators to pay close attention to the three connectors in order to ensure quality learning. The findings guide higher learning institutions to adequately and selectively pay attention to the three connections. Deliberate efforts focusing on students' situations, opinions and concerns are vital for learner satisfaction in developing economies.Originality/valueThis study represents a first attempt to examine the effect of the “right connections” for effective learning in developing economies, using a quantitative approach. The findings bring into attention the role of assessing learner inputs and virtual environment in boosting the effectiveness of e-learning. The findings also result in a model that should lead to increased learner satisfaction through the implementation of right connections. The study “disputes” the relevance of a universal e-learning system.

Authors: Al-Ghazali Basheer M. , Afsar Bilal 
Published: October 2022

PurposeThe construct of psychological capital or PsyCap (consisting of the positive psychological resources of hope, self-efficacy, optimism and resilience) has been demonstrated to relate to employees’ attitudinal and behavioral outcomes. The purpose of this study is to investigate the influence of positive psychological capital on mental health, readiness for organizational change, and job insecurity in the wake of COVID-19 pandemic.Design/methodology/approachData were collected from 567 hotel employees working in hotels in the Kingdom of Saudi Arabia. A quantitative approach was used and employees were requested to fill the questionnaires.FindingsResults show that psychological capital enhances an employee’s mental health and readiness for the organizational change. Moreover, PsyCap is found to negatively impact the perceptions of job insecurity among hotel employees. The study has useful managerial implications for hoteliers, especially, in the wake of COVID-19 pandemic.Originality/valueThis is the first study of its kind to link hotel employees’ positive psychological capital with their perceptions about job insecurity and mental health. COVID-19 pandemic has hit the world fiercely and new normal expects employees to be ready to embrace changes in organizations. This study contributes to the literature on hospitality management by linking psychological capital with hotel employees’ readiness for organizational change in the context of Coronavirus.
Creativity development and Mode 2 theory development: Event system and experiential learning perspectives
Authors: Kulichyova Anastasia , Jooss Stefan , Garavan Thomas 
Published: October 2022

AbstractLiterature on academic‐stakeholder collaboration in the context of HRM is scarce and highlights the challenges linking theory to practice. Drawing on Mode 2 research, we theorise how a structured intervention enables the generation of theoretical insights concerning the development of employee creativity knowledge, skills, and attitudes (KSAs). Utilising event system theory, we reveal how the novelty, criticality, and disruption of a structured intervention fuel an experiential learning process. This process facilitates the development of important individual and team‐based creativity KSAs and is sustained through a learning mindset. We develop insights about theories‐in‐use, HRM theory development, and the micro processes involved in an academic‐stakeholder collaboration including areas of potential tension. From a practice perspective, we highlight the value of structured interventions for creativity KSA development and a strategy to facilitate academic‐stakeholder collaboration.

Published: October 2022

AbstractThe flavan‐3‐ols of 10 primarily plant food byproducts, including Muscat Hamburg grape seed, hawthorn sarcocarp, litchi pericarp, cocoa bean, peanut skin, lotus seedpod, Xinyang Maojian green tea, Cinnamomi cortex, Sargentodoxa cuneata stem, and Cyperus esculentus, leaves were analyzed. Ultrahigh‐performance liquid chromatography–triple quadrupole mass spectrometry was used for the analysis. Cyperus esculentus leaves contained a high amount of procyanidin B1 (198.9 mg/100 g), second only to Muscat Hamburg grape seed (292.9 mg/100 g). Unlike grape seed that contained several procyanidin B isomers with very similar retention times, C. esculentus leaves contained primarily procyanidin B1 with few isomers. Procyanidin B1 was enriched in the ethyl acetate fraction of a 70% methanol extract of C. esculentus leaves and purified at 95% purity by two runs of open column chromatography. Direct chromatography of the plant extract on octadecylsilane and Sephadex LH20 open columns improved the yield of the resultant leaf procyanidin B1 (95% purity) to 0.21‰. The present research demonstrated that the leaves of C. esculentus, byproducts of tigernut, are ideal plant sources for isolating and providing high‐purity procyanidin B1.Practical ApplicationProcyanidin B1 has a broad range of health benefits. Cyperus esculentus is cultivated in many countries with nearly 6190 square hectares (hm2) in the Spanish Mediterranean region in 2020–2021 and over 16,700 hm2 in China in recent years, primarily for its tubers. The byproducts, the leaves of C. esculentus, contain high levels of procyanidin B1, with few isomers that interfere with its isolation and purification. Thus, the leaves of this plant provide a viable source for preparing high‐purity procyanidin B1.

AbstractThe Yusishan deposit is a newly found leptynite‐type niobium and tantalum (Nb‐Ta) deposit, which is located in the Eastern Altun of Gansu Province. The leptynite of the Neoproterozoic Aoyougou Formation occurs more than 10 km long and 3 km wide. In this paper, we carried out a detailed study of the leptynite and related mineralization. The U‐Pb dating of zircon reveals ages of 831 ± 5 Ma and 790 ± 5 Ma for the unmineralized leptynite and 491 ± 4 Ma and 455 ± 4 Ma for the mineralized leptynite. The petrographic and geochemical evidence identified the protolith of the leptynite as alkaline volcanic rocks that erupted during Neoproterozoic at ca. 830 Ma. At ca. 490 Ma, the tectono‐magmatic and metamorphic event triggered remobilization and enrichment of Nb‐Ta as well as other critical metals (REE, Zr, Hf etc) with the formation of industry orebodies in the leptynite strata. The Yushishan deposit presents many similarities with the alkaline volcanic rocks related rare metal deposits in the south Qinling of China and the Brochman, Toogni and Southern Peak Range deposits in Australian. We therefore propose that the Yushishan deposit is a new type (sub‐type) of Nb‐Ta deposit and termed as leptynite type that represents the metamorphic counterpart of the alkaline volcanic rocks related rare metal deposits.

AbstractObjectiveOur aim was to investigate the possible relationship between the serum S100A12 and Toll‐like receptor 4 (TLR4) levels, and the activity of familial Mediterranean fever (FMF) and juvenile idiopathic arthritis (JIA) in accordance with the routine biochemical parameters. Furthermore, the effectiveness of these 2 biomarkers in distinguishing FMF from JIA has been evaluated.MethodSixty‐nine children with FMF, 68 children with JIA, and 35 healthy children were included in this study. S100A12 and TLR4 levels were measured by the sandwich enzyme‐linked immunosorbent assay technique.ResultsIn the FMF patient group, serum S100A12 level was found to be significantly higher than in both the JIA and control groups (P = .000 and P = .000, respectively). Although S100A12 levels were higher in the attack period compared to the attack‐free period, this increase was not statistically significant (P > .05). TLR4 levels were statistically significantly higher in the attack period compared to the attack‐free period in children with FMF (P < .05). Although there was no relationship between S100A12 levels and disease activity, there is a clear correlation between S100A12 and the Auto‐Inflammatory Disease Activity Index in attack‐free FMF patients (r = 0.612 P = .000).ConclusionSerum S100A12 levels were not found to be a potentially valuable biomarker for assessing disease activity in either FMF or JIA. However, TLR4 levels were found to be a valuable biomarker for assessing disease activity in children with FMF. Further research which includes serial monitoring of S100A12 and TLR4 levels in a large cohort will provide detailed information about accuracy of these 2 potential biomarkers in both patients group.
