Published: December 2022

AbstractSuccessful explicit memory encoding is associated with inferior temporal activations and medial parietal deactivations, which are attenuated in aging. Here we used Dynamic Causal Modeling (DCM) of functional magnetic resonance imaging data to elucidate effective connectivity patterns between hippocampus, parahippocampal place area (PPA) and precuneus during encoding of novel visual scenes. In 117 young adults, DCM revealed pronounced activating input from the PPA to the hippocampus and inhibitory connectivity from the PPA to the precuneus during novelty processing, with both being enhanced during successful encoding. This pattern could be replicated in two cohorts (N = 141 and 148) of young and older adults. In both cohorts, older adults selectively exhibited attenuated inhibitory PPA-precuneus connectivity, which correlated negatively with memory performance. Our results provide insight into network dynamics underlying explicit memory encoding and suggest that age-related differences in memory-related network activity are, at least partly, attributable to altered temporo-parietal neocortical connectivity.
Do institutional investors' corporate visits mitigate investors' heterogeneous beliefs? Evidence from China
Authors: Luo Runmei , Ye Yong 
Published: December 2022

PurposeIn this study, the authors argue that the private information obtained and transmitted by institutions during the corporate visits can alleviate the degree of information asymmetry between firms and investors, so institutional visits may influence investors' heterogeneous beliefs. Therefore, the authors investigated whether and how institutional investors' corporate visits affect investors' heterogeneous beliefs.Design/methodology/approachThis study examines whether and how institutional investors' corporate visits affect investors' heterogeneous beliefs using the data of A-share companies from the Shenzhen Stock Exchange (SZSE) during 2013–2019. Using empirical research method, this study designs and conducts an empirical research according to empirical research's basic norms.FindingsThe authors find that institutional visits effectively decrease investors' heterogeneous beliefs, especially institutional investors. Meanwhile, institutional site visits and sell-side institutional visits have a more significant negative effect on investors' heterogeneous beliefs. The findings remain after robustness tests with the alternative variable, instrumental variable, propensity score matching and quantile regression methods.Originality/valueThe development of China's capital market is imperfect, resulting in a strong speculative atmosphere. So, investors' irrational investment behaviors occur from time to time, leading to sizeable heterogeneous beliefs in China's capital market, which increases the risk of investment and is not conducive to the discovery of corporate value and the efficient allocation of resources. Therefore, exploring the factors influencing heterogeneous beliefs and finding ways to alleviate heterogeneous beliefs can reduce the proportion of speculative investors and promote the healthy development of China's capital market.

Published: December 2022

PurposeThe purpose of this paper is to introduce an interactive system that relies on the educational data generated from the online Universities services to assess, correct and ameliorate the learning process for both students and faculty.Design/methodology/approachIn the presented research, data from the online services, provided by a Greek University, prior, during and after the COVID-19 outbreak, are analyzed and utilized in order to ameliorate the offered learning process and provide better quality services to the students. Moreover, according to the learning paths, their presence online and their participation in the services of the University, insights can be derived for their performance, so as to better support and assist them.FindingsThe system can deduce the future learning progression of each student, according to the past and the current performance. As a direct consequence, the exploitation of the data can provide a road map for the strategic planning of universities, can indicate how the learning process can be updated and amended, both online and in person, as well as make the learning experience more essential, effective and efficient for the students and aiding the professors to provide a more meaningful and to-the-point learning experience.Originality/valueNowadays, educational activities in academia are strongly supported by online services, information systems and online educational materials. The learning design in the academic setting is primarily facilitated in the University premises. However, the exploitation of the contemporary technologies and supporting materials that are available online can enrich and transform the educational process and its results.
Top management team gender diversity and the financial performance of Vietnamese SMEs: family and non-family owned firms
Authors: Tran Nhat Minh , Ngo Que Giang , Tran Quyet Thang 
Published: December 2022

Purpose
The purpose of this study is to investigate the impact of the gender diversity of top management teams (TMTs) on the financial performance (FP) of small and medium enterprises (SMEs) in Vietnam. This paper also examines the moderating effect of family control on this relationship.

Design/methodology/approach
Using a sample of SMEs in Vietnam, this paper uses descriptive statistics and balance panel regression with random effect to analyse 5,160 firm-year observations of family- and non-family-owned SMEs between 2011 and 2015.

Findings
The findings demonstrate that gender diversity in TMTs shows a negative relationship with the FP of family-controlled SMEs and no significant impact on FP of non-family SMEs. This study also illustrates a positive curvilinear relationship between the female manager rate in TMTs and firms’ FP in family SMEs.

Research limitations/implications
This research study is limited to data from Vietnamese SMEs. Future studies could investigate these relationships with larger firms and in a broader geographical context.

Originality/value
This study provides a better understanding of the impact of TMT gender diversity on FP in Vietnamese SMEs while considering the moderating effect of family control. The findings support some theories relating to managerial gender diversity and the effect of family control on this diversity in family SMEs.

Published: December 2022

PurposeThe first objective of this study is to analyze whether financial behavior (FB), financial stress (FS), financial literacy (FINLIT) and the locus of control (LOC) influence subjective financial well-being (SFWB) among low-income households in Malaysia. The second objective is to investigate whether the use of digital financial services (DFS) moderates the influence of FB and FS, on SFWB.Design/methodology/approachMotivated by the literature on transformative service research (TRS), this study examines how the use of DFS impact SFWB among low-income households in Malaysia. Low-income households are chosen as they are more likely to be financially excluded and lack financial knowledge and skills. Using an interviewer-administered survey, trained enumerators collected data from 1,948 low-income households in Malaysia, selected using a two-stage sampling based on the National Household Sampling Frame obtained from the Department of Statistics Malaysia.FindingsResults reveal that SFWB is positively influenced by FB and the LOC, and is negatively impacted by FS and FINLIT. The evidence shows that the use of DFS counterintuitively weakened the strength of the relationship between FB and SFWB, but effectively reduced the adverse effect of FS on SFWB.Practical implicationsTo reverse the signs of relationship, financial services marketers need to identify the specific types of DFS that low-income households use in order to provide targeted marketing efforts and financial education to promote the use of DFS on a more holistic basis to increase financial well-being.Originality/valueThe findings of this study add to the body of knowledge deliberating on the opposing effects of technology on consumers' welfare and well-being. This study focuses on the lower-income stratum of Malaysian households as this group of the population is more likely to be financially excluded and have deficiencies in financial knowledge and skills. Findings of this study show that DFS use can actually diminish the positive impact of FB on SFWB while reducing the adverse effect of FS on SFWB.

Published: December 2022

PurposeWith the outbreak of the COVID-19 pandemic, online assessment has become the dominant mode of examination in higher education institutions. However, there are contradictory findings on how students perceive online assessment and its impact on their academic performance. Thus, the purpose of this study is to evaluate the potential impact of online assessment on students' academic performance.Design/methodology/approachThis study proposes a research model based on the task–technology fit theory and empirically validates the model using a survey from students in the UK. In addition, the study conducted four experiments based on paper-based and online assessments and analysed the data using paired sample t test and structural equation modelling.FindingsThe findings show that the use of online assessment has a positive impact on students' academic performance. Similarly, the results from the experiment also indicate that students perform better using online assessments than paper-based assessments.Practical implicationsThe findings provide crucial evidence needed to shape policy towards institutionalising online assessment. In addition, the findings provide assurance to students, academics, administrators and policymakers that carefully designed online assessments can improve students' academic performance. Moreover, the study also provides important insights for curriculum redesign towards transitioning to online assessment in higher education institutions.Originality/valueThis study advances research by offering a more nuanced understanding of online assessment on students' academic performance since the majority of previous studies have offered contradictory findings. In addition, the study moves beyond existing research by complementing assessment results with the views of students in evaluating the impact of online assessment on their academic performance. Second, the study develops and validates a research model that explains how the fits between technology and assessment tasks influence students' academic performance. Lastly, the study provides evidence to support the wide use of online assessment in higher education.
Does family identity matter for earnings management? Evidence from private family firms
Authors: Sundkvist Charlotte Haugland , Stenheim Tonny 
Published: December 2022

PurposeThe purpose of this paper is to examine the role family identity and reputational concerns plays when private family firms engage in earnings management.Design/methodology/approachThe paper is conducted as an archival study using data from private limited liability firms in Norway over the period from 2002 to 2015. The dataset includes financial accounting data and data on family relationships between shareholders, board members and CEOs, where family relationships are determined through bloodlines, adoption and marriage, tracing back four generations and extending out to third cousins. To investigate the incidence of earnings management, the authors employ a measure of accrual-based earnings management (AEM) (Dechow and Dichev, 2002; McNichols, 2002) and a measure of real earnings management (REM) (Roychowdhury, 2006). They use whether or not the family name is included in the firm name (i.e. family name congruence) as a proxy for family members' identification with the family firm and their sensitivity to reputational concerns.FindingsThe authors’ results show that AEM is lower for family-named family firms. Moreover, their findings also indicate that family-named family firms are more likely to select REM over AEM, compared to nonfamily named family firms. This is even more pronounced when detection risk is high (high quality audit proxied by Big 4).Research limitations/implicationsThe quality of the authors’ findings is limited to the validity of their proxy for family firm identification and reputational concerns (the family name included in the firm name). Even though findings from prior research suggest that family name congruence is a valid proxy for identity and reputational concerns (e.g. Kashmiri and Mahajan, 2010, 2014; Rousseau et al., 2018; Zellweger et al., 2013), future research should investigate the validity of these results using alternative proxies for family firm identification. Future research should also investigate whether the authors’ findings are generalizable to public family firms.Practical implicationsThe authors’ results suggest that the risk of AEM is lower for family-named family firms, whereas the risk of REM is somewhat higher, compared to nonfamily named family firms. These results might be relevant for financial accounting users, auditors and supervisory and monitoring bodies when assessing the risk of earnings management.Originality/valueThe paper is, as far as the authors are aware of, the first to investigate the role of family name congruence and detection risk when private family firms select between AEM and REM.
The impact of service climate on gratitude in driving customer outcomes
Authors: Qi Ji Miracle , Peng Yi , Lowman Graham H. , He Xingliang 
Published: December 2022

Purpose
Employee gratitude is often associated with positive customer-related benefits. However, our understanding of employee gratitude is notably underdeveloped within the service literature. To address this issue, this study aims to position employee gratitude within the service profit chain (SPC) framework as a complementary mediator. Further, the authors empirically examine service climate as a central antecedent to employee gratitude and employee customer-oriented behavior as an outcome that triggers an internal and external reciprocal social exchange.

Design/methodology/approach
The examination of the research questions was done across two studies, using employee self-reported data (Study 1) and employee–customer dyadic data (Study 2). In Study 1, the authors investigate how employee gratitude mediates the relationship between service climate and customer-oriented behavior, with employee interpersonal influence functioning as a moderator. In Study 2, the authors examine how customer-oriented behavior, an outcome of Study 1, influences customer satisfaction and customer avoidance, with customer gratitude functioning as a mediator.

Findings
Results from both Study 1 and Study 2 support the proposed relationships. These studies contribute to the service literature by evaluating how and why employee gratitude functions as a significant factor in determining employee and customer behavior within the service context.

Originality/value
This work enriches the gratitude literature by empirically testing a novel theoretical perspective on employee and customer gratitude in service encounters. In doing so, the authors provide a more nuanced understanding of how internal and external processes are connected and potentially reinforced in SPC.

Published: December 2022

AbstractObjectiveTo determine the relative burdens of maternal and perinatal complications for preterm and term pre‐eclampsia.DesignProspective observational cohort study.SettingTwo English maternity units.PopulationUnselected women with singleton pregnancies who developed pre‐eclampsia (International Society for the Study of Hypertension in Pregnancy definition).MethodsOutcomes were ascertained by health record review and compared between pregnancies with preterm (versus term) pre‐eclampsia.Main outcome measuresSevere maternal hypertension, maternal mortality or major maternal morbidity, perinatal mortality or major neonatal morbidity, neonatal unit (NNU) admission ≥48 hours, and birthweight <3rd percentile.ResultsAmong 40 241 singleton pregnancies, 298 (0.7%, 95% confidence interval [CI] 0.66–0.83) and 1194 (3.0%, 95% CI 2.8–3.1) developed preterm and term pre‐eclampsia, respectively. Women with preterm (versus term) pre‐eclampsia more commonly experienced adverse maternal or perinatal events: severe hypertension 18.5% (95% CI 14.5–23.3) versus 13.6% (95% CI 11.7–15.6); maternal mortality/major morbidity 7.4% (95% CI 4.9–10.9) versus 2.2% (95% CI 1.5–3.2); perinatal mortality/major neonatal morbidity 29.5% (95% CI 24.6–34.9) versus 2.2% (95% CI 1.5–3.2); and birthweight <3rd percentile 54.4% (95% CI 48.7–59.9) versus 14.2% (95% CI 12.4–16.3). However, in absolute terms, most maternal complications occurred in women with term pre‐eclampsia, as did a large proportion of perinatal complications: severe hypertension 74.7% (95% CI 68.5–80.0); maternal mortality/major morbidity 54.2% (95% CI 40.3–67.4); perinatal mortality/major neonatal morbidity 22.8% (95% CI 16.1–31.3); NNU admission ≥48 hours 38.1% (95% CI 32.4–44.1); and birthweight <3rd percentile 51.2% (95% CI 45.8–56.5).ConclusionsAlthough adverse event risks are greater with preterm (versus term) pre‐eclampsia, term disease is associated with at least equivalent total numbers of maternal, and a significant proportion of perinatal, adverse events. Increased efforts should be made to decrease the incidence of term pre‐eclampsia.
Gout and risk of venous thromboembolism: A systematic review and meta‐analysis of cohort studies
Authors: Guo Yicong , Zhou Feixiang , Xu Huilan 
Published: December 2022

AbstractBackgroundThe association between gout and venous thromboembolism (VTE) remains ambiguous, and the results of current studies are inconsistent. A systematic review and meta‐analysis of cohort studies were conducted to comprehensively assess the associations between gout and VTE and its subtypes, deep venous thrombosis (DVT) and pulmonary embolism (PE).MethodsPubMed, Web of Science, Embase, Scopus, and the Cochrane Library databases were searched up to June 2021, to identify eligible cohort studies, reporting the association of gout with VTE and its subtypes. We pooled hazard ratios (HRs) with 95% confidence intervals (CIs). Subgroup analysis, sensitivity analysis, and publication bias tests were also conducted.ResultsFive studies involving 642 632 individuals were included. Patients with gout had a statistically significantly higher risk of VTE (HR: 1.33; 95% CI: 1.21, 1.46; P < .001) compared with non‐gout controls, and significant associations were also found between gout and DVT (HR: 1.40; 95% CI: 1.22, 1.62; P < .001) and PE (HR: 1.18; 95% CI: 1.07, 1.30; P = .001). Subgroup analysis showed this association in men (HR: 1.37; 95% CI: 1.14, 1.65; P = .001) and women (HR: 1.36; 95% CI: 1.21, 1.53; P < .001) were consistent (P = .980). Meta‐regression analysis revealed publication year (P = .005) and quality of study (P = .006) contributed to heterogeneity.ConclusionsIn conclusion, our study provided evidence that gout was associated with the risk of VTE and its subtypes DVT and PE. However, more prospective and high‐quality clinical evidence is required to confirm our findings.
Fixed investment or financial assets investment: Evidence from political uncertainty in China
Authors: Yao Chengxue , Jiang Fan , Guo Liang 
Published: December 2022

AbstractUsing a comprehensive dataset of listed firms and detailed turnover data on top provincial leaders in China, we explore how political uncertainty affects a firm's portfolio choice. During political turnover, a firm decreases its fixed investment and increases its financial asset investment, but the promotional effect of political turnover on the financial asset investment of politically dependent enterprises (PDEs) is not obvious. We explain this finding through the mediating effect of stock price informativeness and degree of political dependence. Our results suggest that non‐PDEs rely on market information to make investment decisions, whereas PDEs are also affected by political resource information.
Estimation of genetic heritabilities of human traits in case–control studies
Authors: Hu Die , Chen Shuyue , Zhang Hong 
Published: December 2022

AbstractIt is of great interest to detect missing heritability for human complex traits. Additive genetic effects (ADD), maternal genetic effects (MGE), and parent‐of‐origin effects (POE) play important roles in genetic mechanisms. Methods have been developed in the literature to analyze heritabilities due to ADD, POE, and MGE separately but not simultaneously. In this paper, a new model termed APM is proposed based on mother–child duos genetic data, which orthogonally decomposes heritabilities due to ADD, POE, and MGE. This orthogonal decomposition is biologically interpretable since it ideally characterizes independent contributions due to the three effects. We focus on case–control data that are widely adopted in genetics studies and develop a novel method R‐PCGC by adjusting estimation biases due to sampling bias in case–control studies and imposing nonnegative constraints on the heritability estimates. Large sample properties such as consistency and asymptotic normality are established for R‐PCGC. The desired properties of R‐PCGC (i.e., asymptotic unbiasedness and nonnegativity) are confirmed through simulations. Finally, R‐PCGC regression is applied to a case–control study of preterm births from the Danish National Birth Cohort (DNBC).
