AbstractThough the lateral frontal cortex is broadly implicated in cognitive control, functional MRI (fMRI) studies suggest fine-grained distinctions within this region. To examine this question electrophysiologically, we placed electrodes on the lateral frontal cortex in patients undergoing awake craniotomy for tumor resection. Patients performed verbal tasks with a manipulation of attentional switching, a canonical control demand. Power in the high gamma range (70-250 Hz) distinguished electrodes based on their location within a high-resolution fMRI network parcellation of the frontal lobe. Electrodes within the canonical fronto-parietal control network showed increased power in the switching condition, a result absent in electrodes within default mode, language, cingulo-opercular and somato-motor networks. High gamma results contrasted with spatially distributed power decreases in the beta range (12-30 Hz). These results confirm the importance of fine-scale functional distinctions within the human frontal lobe, and pave the way for increased precision of functional mapping in tumor surgeries.

ABSTRACTMales and females share essentially the same genome but differ in their optimal values for many phenotypic traits, which can result in intra-locus conflict between the sexes. Aphids display XX/X0 sex chromosomes and combine unusual X chromosome inheritance with cyclical parthenogenesis. Theoretical and empirical works support the hypothesis that the large excess of male-biased genes observed on the aphid X chromosome compared to autosomes evolved in response to sexual conflicts, by restricting the products of sexually antagonistic alleles to the sex they benefits. However, whether such masculinization of the X affects all tissues (as expected if it evolved in response to sexual conflicts) or is limited to specific tissues remains an open question. Here, we measured gene expression in three different somatic and gonadic tissues of males, sexual females and parthenogenetic females of the pea aphid. We observed a masculinization of the X in each of the studied tissues, with male-biased genes being 2.5 to 3.5 more frequent on the X than expected. We also tested the hypothesis that gene duplication can facilitate the attenuation of conflicts by allowing gene copies to neo- or sub-functionalize and reach sex-specific optima. As predicted, X-linked copies of duplicated genes having their other copies on autosomes were more frequently male-biased (40.5% of the genes) than duplicated autosomal genes (6.6%) or X-linked single-copy genes (32.5%). These results highlight a peculiar pattern of expression of X-linked genes in aphids at the tissue level and provide further support for sex-biased expression as a mechanism to attenuate intra-locus sexual conflicts.

Authors: Ben Abdallah Mariem , Bahloul Slah 
Published: August 2021

PurposeThis study aims at investigating the impact of the disclosure and the Shariah governance on the financial performance in MENASA (Middle East, North Africa and Southeast Asia) Islamic banks.Design/methodology/approachWe use the Generalized Least Squares (GLS) regression models to check the interdependence relationship between the disclosure, the Shariah governance and the financial performance of 47 Islamic banks (IBs) from ten countries operating in MENASA region. The sample period is from 2012 to 2019. In these regressions models, Return on Assets (ROA) and Return on Equity (ROE) are the dependent variables. The disclosure and the Shariah governance indicators are the independent factors. To measure the Shariah governance, we use the three sub-indices, which are the Board of Directors (BOD), the Audit Committee (AC) and the Shariah Supervisory Board (SSB). Size, Leverage and Age of the bank are used as control variables. We also used The Generalized Method of Moments (GMM) and the three-stage least squares (3SLS) estimations for robustness check.FindingsResult shows a negative relationship between the disclosure and the two performance measures in IBs. Furthermore, as far as the governance indicators are concerned, we found that the BOD and AC, as well as the BOD and SSB, have a positive and significant impact on the ROA and ROE, respectively. This reveals that good governance had a significant association with higher performance in MENASA IBs.Originality/valueThe paper considers both IBs that adopt mandatory as well as voluntary AAOIFI standards and the GLS method to investigate the impact of the AAOIFI disclosure and the Shariah governance on ROA and ROE. Also, it uses the GMM and the 3SLS estimations for robustness check. It is relevant for researchers, policymakers and stakeholders concerned with IBs' performance.
Emerging trends in digital transformation: a bibliometric analysis
Authors: Chawla Raghu Nandan , Goyal Praveen 
Published: August 2021

PurposeUbiquitous digital technologies are driving organisations to embrace non-traditional digitally transformed business models incessantly. Heterogeneous literature contributions have resulted in a spur in the research related to business transformation driven by digital technologies in recent years; consequently, the research under the digital transformation (DT), even though becoming a hotspot, remains very fragmented. The authors endeavour to holistically present the literature's intellectual structure under DT as a concept, its evolving journey and the emerging research streams in the business and management domains using the techniques of bibliometric analysis.Design/methodology/approachBy performing bibliometric analysis on 234 research articles published over the last 20 years in the DT domain, retrieved from Thompson Reuters Web of Science TM, this study culls out thorough insights from the citation, co-citation and keyword analysis. Further emerging research streams were evaluated using VOSviewer software.FindingsThe study depicts an overall incremental trend of year-on-year publications, authors' performance, publication journals, associated institutions and research driving countries, along with key insights from co-citation network analysis. Furthermore, the study evaluates four research areas – organisational impacts, applied applications and insights, operational processes and social aspects, comprising eighteen research streams that comprehensively cover-up research under the DT domain.Research limitations/implicationsThe study contributes to the literature of DT by amalgamating the status of the present research, but more importantly, by deriving the research areas and research streams, which can be further expanded by researchers as future research streams.Practical implicationsFor the practitioners, the study aims to act as a ready reckoner repository with practice-oriented literature references to facilitate them building knowledge and taking effective strategic decisions to harness the benefits of DT more proficiently.Originality/valueThis study illustrates the bibliometric structure of the DT literature and presents insights from the growth of the literature year-on-year.
Matching words with actions: understanding the effects of CSA stance-action consistency on negative consumer responses
Authors: Zhou Ziyuan , Dong Chuqing 
Published: August 2021

PurposeDespite corporate social advocacy (CSA) has become a popular phenomenon, less is known about the potential negative public responses to corporations' CSA involvement and promotion. This paper aims to investigate the main and conditional effects of a new concept, CSA stance-action consistency, on consumers' negative responses to CSA communication.Design/methodology/approachThe study employed a 4 (four types of CSA stance-action consistency) × 2 (CSA record: long vs short) between-subject experimental design. Social issue activism was measured as a continuous variable and treated as a moderator. An online experiment was conducted with participants recruited from MTurk (n = 224).FindingsCSA stance-action consistency significantly predicted negative word-of-mouth and boycott intention. Participants' social issue activism moderated the effects. However, CSA record was not a significant predictor of consumers' negative responses to CSA communication.Originality/valueThis study advances CSA and corporate communication literature by proposing a new concept, CSA stance-action consistency and providing empirical evidence on its effects on consumer responses. Practical implications to CSA promotion were discussed.
Does time perspective influence knowledge hiding? Empirical evidence from Indian employees
Authors: Ruparel Namita , Choubisa Rajneesh , Seth Himanshu , Nagpal Gaurav 
Published: August 2021

Purpose
The current study aims to explore the relationship between time perspective and knowledge hiding at the workplace.

Design/methodology/approach
The research adopts a cross-sectional design. Data were collected using purposive sampling technique from (n = 425) employees representing five sectors of companies.

Findings
Holding onto negative experiences of the past (past negative TP) and perceiving that one cannot control the outcomes of a circumstance (fatalistic TP) predict all three types of knowledge hiding. Staying in a perspective of working towards achieving a goal (futuristic TP) was negatively (although insignificantly) associated with knowledge hiding.

Practical implications
If organizations focus on shifting the time perspective of employees towards the future, KH can be curtailed. Consequently, knowledge management can be enhanced.

Originality/value
A decade of research has focused upon identifying dynamics of knowledge hiding at multiple levels, yet, the influence of TP on knowledge hiding is a novel empirical contribution to literature.
Impact of brand anthropomorphism on ethical judgment: the roles of failure type and loneliness
Authors: Dalman M. Deniz , Agarwal Manoj K. , Min Junhong 
Published: August 2021

Purpose
This paper aims to investigate whether anthropomorphized (i.e. humanized) brands are judged less negatively for competence failures than for moral lapses and how these ethical judgments impact negative word-of-mouth (NWOM) intentions of less-lonely and more-lonely consumers.

Design/methodology/approach
Two scenario-based experiments were conducted, involving a total of 1,375 US mechanical turk (Amazon consumer panel) participants.

Findings
Findings show that brand humanization has an impact on ethical judgments only for less-lonely consumers. More specifically, for less-lonely consumers, a humanizing strategy backfires when the failure is moral but helps the brand when the failure is competence-related. On the other hand, more-lonely consumers judge the situation less negatively overall, and this effect is not impacted by the anthropomorphization strategy. Process tests indicate that these judgments indirectly affect consumers’ intention to spread NWOM following negative events.

Research limitations/implications
Future research could examine the specific process for lonely consumers (i.e. the role of empathy) and manipulate the size of the negative events (i.e. consumer perceptions of moderate vs extreme failures).

Practical implications
Brand managers need to consider their specific situations, as anthropomorphization can have both positive and negative effects depending on the consumers and the failure type (moral vs competence).

Originality/value
Extant research indicates that a humanizing strategy backfires when the market has negative information about the brand. This research introduces types of negative information, as well as consumers’ loneliness as moderators and contributes to the literature in branding, business ethics and word-of-mouth.
Measuring the effectiveness of intermediary loyalty programmes in the motor insurance industry: loyal versus non-loyal customers
Authors: Leiria Manuel , Rebelo Efigénio , deMatos Nelson 
Published: August 2021

PurposeThe insurance industry has not been able to effectively retain its customers and struggles to establish and maintain long-lasting relationships with them. The purpose of this paper is thus to identify the main factors that explain the cancellation of motor insurance policies by individual customers, considering the influence of intermediaries on their decisions.Design/methodology/approachThe data used in this research is based on a sample of 3,500 insurance policies that lapsed during the period of analysis between January and July 2017, against another sample of 3,500 policies that did not lapse, from a major insurance company in Portugal. Binary logistic regression was used for data analysis, using IBM SPSS software.FindingsAggressive tactics by insurance companies for customer acquisition may induce the cancellation of insurance policies. More valuable customers, the policies with higher premiums and recent claims, as well as the ancillary intermediaries and agents, are determinants of insurance cancellation. Conversely, the payment of policies by direct debit and without instalments reduces the probability of cancellations.Research limitations/implicationsThe main limitation of this study is the restriction on data access. Insurance companies are significantly resistant to sharing their customer data – including with academic researchers – even in an anonymised form.Practical implicationsThe paper highlights internal and external practices of insurance companies that should be reformulated to significantly improve their performance regarding product cancellation, related to customer information management, mistrust behaviours related to stakeholders and new value propositions that deepen the relationships with intermediaries.Originality/valueThis research developed a framework with which to identify the factors that are mainly associated with motor insurance cancellation and to predict its likelihood.
The development and practice of authentic leadership: a cultural lens
Authors: Williams Elizabeth Nutt , Grande Steven , Nakamura Yoshie Tomozumi , Pyle Lori , Shaw Gary 
Published: August 2021

Purpose
Despite increasing interest and scholarship on authentic leadership, definitions of the construct remain contested. In addition, limited research exists on its enactment in practice and its sustainability in a global context. The purpose of this study was to explore the practice of authentic leadership and understand more about how it is cultivated and sustained.

Design/methodology/approach
To address these issues, an international sample of leaders nominated by peers as exemplifying authenticity in their leadership was interviewed. This study used consensual qualitative research (CQR; Hill, 2012; Hill et al., 1997), a team-based, exploratory methodology, to conduct data analysis.

Findings
This study describes the results of the analysis, highlighting leaders’ beliefs, values and behaviors; their leadership development and the barriers and supportive factors they experienced as leaders. The findings from this exploratory analysis across all cases, including subgroups, may help contextualize the complexity of authentic and sustainable leadership and provide better understanding of authentic leadership development.

Research limitations/implications
Additional research on social identities and training in leadership are critical. The results of this study suggest new directions in studying the development of authentic leaders as well as in researching the experiences of organizations and team members.

Practical implications
This study provides insight and direction for individuals and organizations seeking to better understand the practice of authentic leadership, its development and how it can be sustained over time and across contexts and social identities.

Originality/value
This exploratory approach involving interviews with leaders around the globe provides information about the direct lived experiences of leaders identified as authentic by their peers. This study further highlights the leaders’ critical leadership beliefs and practices, as well as ways in which they cultivated and learned to sustain their leadership practices. This study also sheds light on ways in which experiences might differ across gendered and cultural contexts.
Culture and annual report readability
Authors: Noh Minyoung 
Published: August 2021

PurposeThis study aims to examine the effect of state culture on the readability of narrative disclosures in annual reports based on firms located in all 50 states of the USA.Design/methodology/approachThe author uses the cultural tightness and looseness (Harrington and Gelfand 2014) index at the state level and the BOG index (Bonsall and Miller, 2017) as the primary measures of annual report readability.FindingsUsing US data from 1994 to 2019, this study finds that the state level of cultural tightness in which firms are located positively affects firms’ annual report readability. In addition, the study finds that the positive effect of cultural tightness on annual report readability is pronounced in subgroups with high litigation risk while the result does not hold with subgroups that have low litigation risk. The results are robust when alternative proxies for annual report readability are used and historical location and the states in which firms are incorporated are considered.Originality/valueThis study contributes to the growing literature on the determinants of readability in annual report because firms’ narrative disclosure in annual report varies depending on the information environment, litigation risk, embedded in each state culture where firms are located.

Authors: Albashiti Belal , Hamid Zeeshan , Aboramadan Mohammed 
Published: August 2021

PurposeBuilding on conservation of resources theory and unfolding theory of turnover, this paper aims to propose a model of the effects of despotic leadership on employees’ job satisfaction and turnover intention in the hospitality industry. In this model, the authors theorize psychological distress to play an intervening role among the aforesaid linkages.Design/methodology/approachThe data were collected in three-waves from 212 employees working in Palestinian restaurants. A covariance-based matrix in structural equation modeling was used to verify the proposed linkages in the study. A marker variable was used to control the common method bias.FindingsThe results showed that despotic leadership has a direct negative effect on job satisfaction and a positive indirect effect on turnover intentions. Besides, psychological distress showed to play significant mediating effects among the aforementioned relationships.Practical implicationsThis study gives insights to the hospitality industry on how despotic leadership can be destructive and lead to negative consequences.Originality/valueThis study is unique, as it is the first study conducted on despotic leadership in a hospitality setting. The study responded to scholarly calls made to enrich the literature pertaining to despotic leadership and its outcomes.
