Eph/ephrin signalling in the developing brain is regulated by tissue stiffness
Authors: Sipkova Jana , Franze Kristian 
Published: February 2024

SummaryEph receptors and their membrane-bound ligands, ephrins, provide key signals in many biological processes, such as cell proliferation, cell motility and cell sorting at tissue boundaries. However, despite immense progress in our understanding of Eph/ephrin signalling, there are still discrepancies betweenin vitroandin vivowork, and the regulation of Eph/ephrin signalling remains incompletely understood. Since a major difference betweenin vivoand mostin vitroexperiments is the stiffness of the cellular environment, we here investigated the interplay between tissue mechanics and Eph/ephrin signalling using theXenopus laevisoptic pathway as a model system.Xenopusretinal neurons cultured on soft substrates mechanically resembling brain tissue showed the opposite response to ephrinB1 compared to those cultured on glass.In vivoatomic force microscopy (AFM)-based stiffness mapping revealed that the visual area of theXenopusbrain, the optic tectum, becomes mechanically heterogeneous during its innervation by axons of retinal neurons. The resulting stiffness gradient correlated with both a cell density gradient and expression patterns of EphB and ephrinB family members. Exposingex vivobrains to stiffer matrices or locally stiffening the optic tectumin vivoled to an increase in EphB2 expression in the optic tectum, indicating that tissue mechanics is an important regulator of Eph/ephrin signalling. Similar mechanisms are likely to be involved in the development and diseases of many other organ systems.
Social contacts, neighborhoods and individual unemployment risk
Authors: Poggi Ambra 
Published: February 2024

PurposeThe aim of this paper is to empirically investigate whether social contacts can mediate the way in which current unemployment impacts future unemployment.Design/methodology/approachWe use 2006–2017 data from the Household Income and Labour Dynamics in Australia (HILDA) survey and a dynamic random-effects model to describe the evolution of individual unemployment status over time.FindingsOnce controlled for the local context where individuals live and create friendships, we find that above-average social contacts reduce unemployment persistence. However, social contacts seem to be slightly less effective in deprived neighborhoods. These findings are consistent with the idea that individuals obtain information about job opportunities through a network of social contacts, and unemployment may lead to a decay of social capital, making it more difficult to find employment in future periods. Our results also show that neighborhood deprivation increases individual unemployment risk, while above-average neighborhood cohesion reduces the probability of unemployment in deprived neighborhoods.Originality/valueAlthough many studies have been published on unemployment persistence, to the best of the author's knowledge, this is the first study quantifying the impact of social contacts on unemployment persistence. The study also offers fresh empirical evidence on the impact of neighborhood characteristics on unemployment risk.

Authors: Ray Bhumika , Sengupta Atri , Varma Arup 
Published: February 2024

Purpose
Despite the popularity of gig employment amid the changing business landscape, gig scholarship is somewhat limited and the untold reality about gig is yet to be fully revealed. This study aims to critically address the nature of gig employment, its ambiguities, evolution, theoretical premises and the appropriate future road ahead.

Design/methodology/approach
This paper adopts a dual analytical approach – bibliometric and thematic analyses. After incorporating the exclusion–inclusion criteria, the authors identified 2,135 articles for the bibliometric analyses by using VOSviewer. Additionally, for the deep-delving synthesis, the authors conducted thematic analyses following Braun and Clarke (2006), based on 351 papers.

Findings
The findings revealed that gig work, in its different forms, is emerging as an alternative work arrangement with respect to the future of work. This study also identified multilevel perspectives of gig employment along with its holistic nomological network. Finally, this study offers some critical research directions that should help enhance the theoretical and practical strengths of this nascent scholarship in future.

Research limitations/implications
The review findings are limited in nature owing to the paucity of quality research papers published in the said domain.

Practical implications
The paper brings more clarity to what gig is and isn’t, along with its critical perspectives from multilevel lenses.

Originality/value
This paper identifies critical perspectives related to gig work and suggests appropriate directions for future gig work related scholarship.

Authors: Platitsa Vasiliki , Sardianou Eleni , Abeliotis Konstantinos , Mitoula Roido 
Published: February 2024

Purpose
This study aims to the perceptions of the administration of Greek universities on sustainable development and the role of the administration in the implementation of corresponding practices. Specifically, it examines management’s perception and contribution to sustainable development and assesses the sustainability initiatives taking place in universities and the factors that influence their implementation. The obstacles and motivations in the implementation of these actions are also investigated.

Design/methodology/approach
For the empirical analysis, a survey was conducted during the period March–June 2022, addressing questionnaires to 12 rectors or vice rectors dealing with the sustainability of the respective 12 Greek universities. Secondary data about their sustainability practices were also collected from the institutions’ official Web pages.

Findings
The results show that management’s perception of sustainable development mainly concerns the conservation of resources for future generations and the balancing of the economy. Moreover, the findings indicate that universities play a significant role in achieving sustainability by contributing to the educational process, conducting research and serving as a model of sustainability for both the educational community and society as a whole. Financial and institutional barriers are characterized as the most important obstacles for adopting sustainability practices. The most popular motives to promote sustainability issues are financial support of universities, in addition to the governmental support of the leadership and, in particular, of the rectorate authorities.

Originality/value
To the best of the authors’ knowledge, this study is the first conducted among the Greek universities that focuses on administration’s viewpoint and contributes to the international dialogue on the implementation of sustainability by higher education institutions. The results provide preliminary evidence of top management responses to endorse sustainability activities at the higher education institutes in the broader area of Eastern Europe.
Moment or movement – the heterogeneous impact of the Black Lives Matter movement on personal and societal charitable crowdfunding campaigns
Authors: Seutter Janina , Müller Michelle , Müller Stefanie , Kundisch Dennis 
Published: February 2024

PurposeWhenever social injustice tackled by social movements receives heightened media attention, charitable crowdfunding platforms offer an opportunity to proactively advocate for equality by donating money to affected people. This research examines how the Black Lives Matter movement and the associated social protest cycle after the death of George Floyd have influenced donation behavior for campaigns with a personal goal and those with a societal goal supporting the black community.Design/methodology/approachThis paper follows a quantitative research approach by applying a quasi-experimental research design on a GoFundMe dataset. In total, 67,905 campaigns and 1,362,499 individual donations were analyzed.FindingsWe uncover a rise in donations for campaigns supporting the black community, which lasts substantially longer for campaigns with a societal than with a personal funding goal. Informed by construal level theory, we attribute this heterogeneity to changes in the level of abstractness of the problems that social movements aim to tackle.Originality/valueThis research advances the knowledge of individual donation behavior in charitable crowdfunding. Our results highlight the important role that charitable crowdfunding campaigns play in promoting social justice and anti-discrimination as part of social protest cycles.
Performance and returns volatility of banks in India: public versus private sector
Authors: Singh Kuldeep 
Published: February 2024

PurposeThis current study draws a comparison between the performance indicators of public sector banks (PSBs) and private sector banks (or non-PSBs) in India. The study controls for the impact of COVID-19.Design/methodology/approachThe study uses strongly balanced panel data for seven years of 12 PSBs and 10 non-PSBs from the Nifty PSU Bank Index and Nifty Private Bank Index. The study applies panel data methodology to arrive at the results.FindingsThe study demonstrates that the behavior of indicators of performance and returns volatility for PSBs and non-PSBs differs substantially. While factors like capital adequacy ratio (CAR), cost management (COST), liquidity (LIQ), inflation and economic growth exhibit a similar impact on both categories of Indian banks, the effect of credit risk (RISK), market power (POWER) and COVID-19 on performance and returns stability is different for PSBs and non-PSBs.Research limitations/implicationsThere is a limited sample size of banks in India.Practical implicationsPSBs and non-PSBs need distinct treatments when calibrating performance indicators.Social implicationsThe performance and stability of banks are essential for society at large, the depositors and the investors.Originality/valueThe study provides vibrant implications for insight for banks to calibrate the variables that determine performance and stability, regulators and policymakers for effective governance of the banking ecosystem and effective utilization of public funds and capital. The findings are relevant for policymaking today, when the government is considering the privatization of a few PSBs.
From hurdles to heights: blueprint for tackling distributed ledger technology challenges in the construction sector of a developing economy
Authors: Oke Ayodeji Emmanuel , Aliu John , Ehiosun Lydia Uyi , Ebekozien Andrew , Rotimi Akinrolade Ayowole 
Published: February 2024

Purpose
The emergence of distributed ledger technology (DLT) has transformed the way construction industries approach data management, ushering in an era of increased transparency, security and efficiency. The purpose of this study is to investigate the strategies to promote the adoption of DLT in the Nigerian construction sector. This was done to address the challenges that hinder the widespread adoption of DLT within the Nigerian construction sector.

Design/methodology/approach
A comprehensive literature review informed the design of a structured questionnaire for data collection. The questionnaire was distributed among diverse construction professionals to explore their perceptions of potential strategies. The collected data were analyzed using the Shapiro–Wilk test for data distribution, while mean values and standard deviations were used to facilitate the ranking of strategies. The Kruskal–Wallis H-test was used to assess opinion differences, and exploratory factor analysis was applied to uncover underlying dimensions.

Findings
The findings revealed the top five strategies for DLT adoption as conducting workshops and seminars to educate professionals, collaborating with universities for DLT courses, encouraging joint projects for shared insights, forming consortia for DLT standards and allocating funding for DLT research in construction. Through factor analysis, the strategies identified were categorized into four principal clusters: awareness and education advancements, government support and incentives, industry collaboration and standards and pilot projects and demonstrations.

Originality/value
While prior studies have identified barriers to DLT adoption and offering recommendations, this research advances the field by empirically investigating and assessing several of these strategies proposed in various studies. This approach provides valuable insights that go beyond existing research, offering a deeper understanding of the practical and contextual dynamics influencing DLT adoption in the construction sector.
Why do employees hide knowledge after working hours? Linking non-working time ICT demands to deceptive knowledge hiding
Authors: He Peixu , Zhou Hanhui , Zhou Qiongyao , Jiang Cuiling , Anand Amitabh 
Published: February 2024

Purpose
Employees may adopt deceptive knowledge hiding (DKH) due to nonworking time information and communication technology (ICT) demands. Drawing from the conservation of resources (COR) theory, this study aims to develop and test a model of deceptive knowledge hiding (DKH) due to nonworking time information and communication technology (ICT) demands.

Design/methodology/approach
In total, 300 service employees have joined the three-wave surveys. Path analysis and bootstrapping methods were used to test the theoretical model.

Findings
Results suggest that knowledge requests during nonworking time could deplete employees’ resources and increase their tendency to engage in DKH, whereas work recovery and emotional exhaustion mediate this relationship. In addition, employees’ work–family segmentation preferences (WFSP) were found to moderate the direct effects of nonworking time ICT demands on employees’ work recovery and emotional exhaustion and the indirect effects of knowledge requests after working hours on DKH through employees’ work recovery and emotional exhaustion.

Originality/value
First, the findings of this study shed light on the relationship between knowledge requests during employees’ nonworking time and knowledge hiding, suggesting that knowledge hiding could occur beyond working hours. Second, drawing on COR theory, this study explored two joint processes of resource replenishment failure and depletion and how nonworking time ICT demands trigger knowledge hiding. Third, the interaction effect of individuals’ WFSP and nonworking time factors on knowledge hiding deepens the understanding of when nonworking time ICT demands may induce knowledge hiding through various processes.
Oil rent, corruption and economic growth relationship in Nigeria: evidence from various estimation techniques
Authors: David Joseph , Gamal Awadh Ahmed Mohammed , Mohd Noor Mohd Asri , Zakariya Zainizam 
Published: February 2024

Purpose
Despite the huge financial resources associated with oil, Nigeria has consistently recorded poor growth performance. Therefore, this study aims to examine how corruption and oil rent influence Nigeria’s economic performance during the 1996–2021 period.

Design/methodology/approach
Various estimation techniques were used. These include the bootstrap autoregressive distributed lag (ARDL) bounds-testing, dynamic ordinary least squares (DOLS), the fully modified OLS (FMOLS) and the canonical cointegration regression (CCR) estimators and the Toda–Yamamoto causality.

Findings
The bounds testing results provide evidence of a cointegrating relationship between the variables. In addition, the results of the ARDL, DOLS, CCR and FMOLS estimators demonstrate that oil rent and corruption have a significant positive impact on growth. Further, the results indicate that human capital and financial development enhance economic growth, whereas domestic investment and unemployment rates slow down long-term growth. Additionally, the causality test results illustrate the presence of a one-way causality from oil rent to economic growth and a bi-directional causal relationship between corruption and economic growth.

Originality/value
Existing studies focused on the effects of either oil rent or corruption on growth in Nigeria. Little attention has been paid to the exploration of how the rent from oil and the pervasiveness of corruption contribute to the performance of the Nigerian economy. Based on the outcome of this study, strategies and policies geared towards reducing oil dependence and the pervasiveness of corruption, enhancing human capital and financial development and reducing unemployment are recommended.
Business model transition and entrepreneurial small businesses: a systematic literature review
Authors: Leipziger Martin , Kanbach Dominik K. , Kraus Sascha 
Published: February 2024

PurposeSmall businesses are facing evolving environments, with a resulting need to shift their traditional approaches toward new business models (BMs). Many face difficulties within this transition process due to their specific resource constraints. Based on this, incremental changes to the BM – business model transition (BMT) – are proposed as comprising a suitable framework for entrepreneurial small businesses.Design/methodology/approachThis study conducts a systematic literature review (SLR) to cover a broad range of relevant literature within a final sample of 89 articles. The SLR method was chosen to integrate research in a systematic, transparent and reproducible way. For qualitative analysis and framework derivation, the study draws on a thematic ontological analysis.FindingsThe broad search criteria, focusing on BM, incremental BM changes and small businesses, pave the way for a comprehensive overview of multiple research streams of BM concepts (e.g. digital and sustainable BM). The main contribution of this work is the resulting holistic BMT framework, comprising the main parts BM innovation, external antecedents (transition of environment, entrepreneurial ecosystem), internal antecedents (dynamic capabilities, entrepreneurial orientation, resilience, strategy) and output (firm performance).Practical implicationsThe framework provides guidance for entrepreneurs and entrepreneurial managers to implement and complete BMT in small businesses. Furthermore, the presented paper sets a future research agenda focusing on small businesses structured according to the derived framework.Originality/valueThis study provides the first SLR of existing BM concepts with a small-business specific perspective on BMI and a focus on various incremental BM changes.
Economics of Information Search and Financial Misreporting
Authors: KIM JUNG MIN 
Published: February 2024

ABSTRACTI examine how investors’ search for different types of information affects managers’ reporting decisions. I distinguish investors’ search for information about firm fundamentals (“fundamental search”) from their search for information about managers’ incentives (“incentive search”). Based on a parsimonious model of misreporting, I predict that fundamental search reduces the earnings response coefficient, which reduces managers’ benefits from misreporting, resulting in less misreporting. In contrast, incentive search increases the earnings response coefficient, which increases the benefits from misreporting, resulting in more misreporting. I test these predictions using an empirical technique that classifies EDGAR downloads as fundamental search or incentive search. Consistent with my theoretical predictions, I find that fundamental (incentive) search is negatively (positively) related to the earnings response coefficients and intentional restatements. I confirm my findings in two distinct empirical settings where the costs of information search exogenously changed: the adoption of XBRL and the electronic filing mandate of Form 4s. Collectively, the results show that investors’ information demand can shape managers’ reporting decisions, and its effects can vary depending on the type of information investors search for.
When HRM meets politics: Interactive effects of high‐performance work systems, organizational politics, and political skill on job performance
Authors: Chang Huikun , Pak Jongwook 
Published: February 2024

AbstractRecently, scholars in strategic human resource management have attended to internal dynamics that give rise to variability within organizations. Given that workplace politics is an inherent and inevitable part of organizational life, this study investigates the interplay of organizational politics (OP) and an individual's political skill (PS) in shaping the relationship between high‐performance work systems (HPWS) and employees' performance behaviors. Utilizing multilevel, multisource data collected in two phases from 187 employees nested within 47 workgroups, we explore cross‐level three‐way interaction effects involving group‐level HPWS, OP, and individual‐level PS on task performance and organizational citizenship behaviors. The results reveal that the positive impact of HPWS is more pronounced among individuals with strong PS when OP is low. Conversely, in high OP environments, the HPWS–performance relationship becomes negative for those with poor PS, while individuals with strong PS continue to exhibit positive outcomes. These findings contribute to a deeper understanding of the intricate and nuanced nature of the HPWS–performance relationship.
Counting in qualitative fieldwork: Notes from a large urban park
Authors: Layton Jack 
Published: February 2024

AbstractThis paper reflects on the practice of counting physical activity in a large urban park as a social research method. Using a page of tabulated numbers from inside my notebook as a launching off point, it discusses how this quantitative method aided my qualitative inquiry. It discusses some of the strengths and weaknesses of the method as well as offering a reflection on how geographers and urban scholars might use counting as a regular part of their research practice. By opening up my notebook I reflect on how I went about assembling evidence as a researcher in my investigation of a busy urban space, and how it helped me to understand the social life of a well‐used park in situ as I developed an argument about conceptualising parks as social infrastructures.
Idiopathic multicentric Castleman disease (iMCD)‐idiopathic plasmacytic lymphadenopathy: A distinct subtype of iMCD‐not otherwise specified with different clinical features and better survival
Authors: Gao Yu‐han , Liu Yan‐ting , Zhang Miao‐yan , Li Si‐yuan , Fajgenbaum David C. , Zhang Lu , Li Jian 
Published: February 2024

SummaryIdiopathic multicentric Castleman disease (iMCD) is subclassified into iMCD‐thrombocytopenia, anasarca, reticulin fibrosis, renal dysfunction, organomegaly (TAFRO) and iMCD‐not otherwise specified (NOS) according to the Castleman Disease Collaborative Network (CDCN) consensus criteria. With a deeper understanding of iMCD, a group of patients with iMCD‐NOS characterised by polyclonal hypergammaglobulinaemia, plasmacytic/mixed‐type lymph node histopathology and thrombocytosis has attracted attention. This group of patients has been previously described as having idiopathic plasmacytic lymphadenopathy (IPL). Whether these patients should be excluded from the current classification system lacks sufficient evidence. This retrospective analysis of 228 patients with iMCD‐NOS identified 103 (45.2%) patients with iMCD‐IPL. The clinical features and outcomes of patients with iMCD‐IPL and iMCD‐NOS without IPL were compared. Patients with iMCD‐IPL showed a significantly higher inflammatory state but longer overall survival. No significant difference in overall survival was observed between severe and non‐severe patients in the iMCD‐IPL group according to the CDCN severity classification. Compared with lymphoma‐like treatments, multiple myeloma‐like and IL‐6‐blocking treatment approaches in the iMCD‐IPL group resulted in significantly higher response rates and longer time to the next treatment. These findings highlight the particularities of iMCD‐IPL and suggest that it should be considered a new subtype of iMCD‐NOS.
