Authors: Chou Shih Yung , Luo Jiaxi , Ramser Charles 
Published: June 2022

PurposeGiven the disruption of the COIVD-19 pandemic in higher education, this study seeks to understand possible changes in students’ ratings and textual reviews of higher education institutions posted on Niche College Rankings (niche.com) prior to and after the COVID-19 pandemic.Design/methodology/approachThis study utilized a text analytics technique to identify the positive and negative keywords of students’ sentiments expressed in their textual reviews provided on niche.com. After identifying the positive and negative sentimental keywords, this study performed ordinal logistic regressions and analyzed the statistical effects of these positive and negative sentimental keywords on the types of student ratings of a higher education institution.FindingsResults from 15,666 online reviews provided by students on niche.com indicate the following. First, eight positive sentimental keywords such as “outstanding” and “love” have a significant impact on students’ positive ratings of a higher education institution prior to COVID-19, whereas eight positive sentimental keywords such as “amazing” and helpful” have a significant impact on students’ positive ratings of a higher education institution after COVID-19. Second, twenty-eight negative sentimental keywords such as “difficult” and “frustrating” have a significant impact on students’ negative ratings of a higher education institution prior to COVID-19, whereas thirty negative sentimental keywords such as “complex” and “hate” have a significant impact on student negative ratings of a higher education institution after COVID-19.Originality/valueThis study is one of the first few studies investigating higher education institution ratings and reviews provided by students. Additionally, this study provides an understanding of student positive and negative sentiments expressed in textual reviews posted prior to and after the COVID-19 pandemic. By doing so, this study provides a basis for future research seeking to understand student textual reviews of higher education institutions. Additionally, this study offers higher education administrators some recommendations that may foster student positive campus experience while minimizing negative sentiments.
Caught in the spider's web: an investigation of dysfunctional behavioural patterns in a family firm
Authors: Ferrari Filippo 
Published: June 2022

PurposeDrawing on the theory of goal systems applied to family business this case study focuses on the interdependence between non-economic goals and family goals, in order to identify if and how achieving non-economic goals generates dysfunctional behavioural patterns for family members in the long term.Design/methodology/approachThis study used an inductive, 20-year longitudinal case-study based methodology.FindingsThis case study shows how the business family faces ethical/affective dimensions, struggling every day for a balance and often undermining the legitimisation and differentiation of its children. Findings show that the achievement of non-economic goals can occur to the detriment of family goals, such as by generating a dysfunctional system, specifically in business family adaptability.Research limitations/implicationsThe principal limitation is that this single case study evidently does not allow for complete generalization of the findings.Practical implicationsThis case study makes a contribution to alerting the family business system to the long-term risk they face in trying to simultaneously maintain both harmony/cohesion and ethics/responsibility. Practitioners and consultants are therefore called on to help family firm owners with adopting a strategic vision by considering possible long-term counterfinal (i.e. mutually incompatible) goals.Social implicationsSMEs are the most widespread type of firm in the world, and consequently dysfunctional behavioural patterns within business families represent a prominent socio-economical problem for policy makers and institutions.Originality/valueThis study shows that, in the long term, that which is perceived to be a desirable goal can transpire to be a dysfunctional pattern. In doing so, this research introduces a new point of view to the literature on goal systems in family business.
Educational leaders' coping with loneliness: the unique perspective of school principals and vice-principals
Authors: Dor-haim Peleg 
Published: June 2022

PurposeThe purpose of this study was to explore school principals' and vice-principals' perceptions of their strategies of coping with loneliness at work. The study posed two questions: (1) how do educational leaders perceive their strategies of coping with loneliness at work? (2) What are the differences in the style of coping with loneliness between school principals and vice-principals, as they perceive it?Design/methodology/approachBased on 41 semi-structured interviews with 22 school principals and 19 vice-principals three main coping strategies were found.FindingsThis study differentiated between three strategies for coping with a sense of loneliness in the workplace: (1) receiving support from within and outside of the school, (2) action-oriented coping strategy, and (3) perspective-focused coping strategy. Some of these strategies characterized school principals while others characterized vice-principals.Practical implicationsEducational leaders' familiarity with a variety of coping strategies with a sense of loneliness, appropriate to their specific difficulty should be expanded.Originality/valueThe issue of coping with loneliness has barely been explored in the context of leaders and managers. This issue is of particular importance, given the negative effects of loneliness on leaders' mental well-being and their functioning at work.
The PropTech investors' dilemma – What are the key success factors that secure survival?
Authors: Kassner Andreas Joel , Cajias Marcelo , Zhu Bing 
Published: June 2022

PurposeThe real estate industry is known as a late adopter when it comes to changes and innovations. While the industry is slowly evolving, parts of the sector are increasingly being conquered by property-related start-ups, known as “PropTechs”. These companies offer solutions and cutting-edge technologies to increase efficiencies and solve industry-wide problems. However, little is known about these companies' survival. This paper analyses the survival rate of PropTech firms and the determinants.Design/methodology/approachBased on a sample of 1,052 firms, factors that influence the firms' survival rate are analysed using the Cox Proportional Hazards Model, which is expanded with non-linear splines to capture turning points in the survival.FindingsThe authors find that in addition to the size, financing condition plays the most critical role in the success of Prop-Tech firms, including the number of financing rounds and maximum number of investors over lifetime. Moreover, the relationships are non-linear. Founding years and technology focus can also statistically influence the success rate. Companies founded before 2008 focussing on Sustainability Technology, Data and Business Analytics, Real Estate-related FinTech and Visualisation show the highest success rates.Practical implicationsThe results are critical for investors interested in PropTechs to understand the success of their investments better. The importance of financing conditions shows that both investors and PropTechs may benefit from better financing processes that provide funds in a timelier manner.Originality/valueThe authors exploit a new and comprehensive data set that includes over 6,000 PropTechs globally. The authors' study fills in the literature gap on the determinants of the survival rate of PropTechs.
Business against violence: assessing how business impacts peace
Authors: Katsos John , Forrer John 
Published: June 2022

Purpose
This study aims to advance theory on business in conflict zones (often termed “business for peace”) so as to enable the categorization of empirical work testing the field’s assertions.

Design/methodology/approach
In this conceptual paper, the authors present an assessment framework for categorizing research on the peace impacts of business entities, as suggested by Oetzel et al. (2009). This framework allows researchers to make comparisons across methodologies and fields on whether particular business actions contribute to peace.

Findings
Drawing on peace and conflict research, this study proposes a three-stage process in response to the presence of violence and its level of intensity, identify applicable research methods to assess the impact of business actions on peace at each of the three stages and offer suggestions for future research.

Social implications
Categorizing research impacts in the business for peace field will allow societal actors to evaluate the efficacy of claimed business for peace efforts. This is particularly true for those in within international organizations and non-governmental organizations (NGOs) who work with the private sector and for those in the private sector whose work attempts to enhance peace.

Originality/value
As a societal actor, business has a key role to play in peacemaking. The past decade has seen a proliferation of qualitative research work surrounding this theme. In a seminal work, Oetzel et al. (2009) suggested a research framework building on the theories of Fort and Schipani (2004) and suggested five actions that businesses could take to promote peace. To the best of the authors’ knowledge, this paper is the first one to respond to that suggestion by proposing a means of categorizing the impacts of business actions.
Advances of genetic engineering in streptococci and enterococci
Authors: Kurushima Jun , Tomita Haruyoshi 
Published: June 2022

AbstractIn the post‐genome era, reverse genetic engineering is an indispensable methodology for experimental molecular biology to provide a deeper understanding of the principal relationship between genomic features and biological phenotypes. Technically, genetic engineering is carried out through allele replacement of a target genomic locus with a designed nucleotide sequence, so called site‐directed mutagenesis. To artificially manipulate allele replacement through homologous recombination, researchers have improved various methodologies that are optimized to the bacterial species of interest. Here, we review widely used genetic engineering technologies, particularly for streptococci and enterococci, and recent advances that enable more effective and flexible manipulation. The development of genetic engineering has been promoted by synthetic biology approaches based on basic biological knowledge of horizontal gene transfer systems, such as natural conjugative transfer, natural transformation, and the CRISPR/Cas system. Therefore, this review also describes basic insights into molecular biology that underlie improvements in genetic engineering technology.
Drivers of Global Banking Stability in Times of Crisis: The Role of Corporate Social Responsibility
Authors: Li Teng , Trinh Vu Quang , Elnahass Marwa 
Published: June 2022

AbstractThis study examines the effect of environmental and social (ES) activities on global banking stability in the shadow of the COVID‐19 pandemic. Using a sample of 244 commercial banks across 52 countries from 2002 to 2020, we provide evidence that during the global health crisis, banks with higher levels of ES activities are more financially stable (i.e. lower credit and liquidity risk exposures). Drawing on social capital and stakeholder theories, we find that ES activities increase firm‐level social capital and establish a stakeholder‐centred culture within a bank, strengthening social trust and public confidence in the bank's risk oversight. Accordingly, ES activities constrain excessive and aggressive bank risk‐taking during turbulent times when short‐termism prevails. Our additional analysis reveals that investors value such beneficial effects of ES activities. The findings offer new insights into the increasingly significant roles of social capital creation and stakeholder‐centred culture in maintaining banks’ financial stability.

Published: June 2022

AbstractIntroductionThe purpose of this study is to clarify the clinical parameters of therapeutic apheresis (TA) induction in clinically amyopathic dermatomyositis patients with rapid progressive interstitial lung disease.MethodsLiterature publications prior to November 2021 from PubMed and Ichushi‐Web were used. We collected details of TA and clinical features. The data were divided into two groups determined by the outcome, survived and deceased. Then, we estimated clinical parameters between them.ResultsThere were 151 cases, 134 of which had reported outcomes and 64 of which were positive for the anti‐MDA5 antibody. Eighty patients survived. Forty‐eight patients were treated with plasma exchange and 34 with polymyxin‐B immobilized fibers direct hemoperfusion. Regarding clinical parameters, only the PaO2 to FiO2 (P/F) ratio was useful. The cut‐off point of the P/F ratio was 174 on the ROC curve.ConclusionThe parameter for induction is considered when the P/F ratio is lower than 200.

Published: June 2022

AbstractMinimally invasive esophagectomy has gradually been accepted as an active treatment option for surgery of esophageal cancer. However, there is no consensus about how to perform the procedures in the thoracic and abdominal phase including anastomosis in the neck (McKeown) or chest (Ivor Lewis), VATS, robotic‐assisted or reduced port approaches or various endoscopic abrasion techniques. Further studies to investigate the roles of these novel techniques are required to treat the various patient populations.
Real earnings management: A review of the international literature
Authors: Habib Ahsan , Ranasinghe Dinithi , Wu Julia Yonghua , Biswas Pallab Kumar , Ahmad Fawad 
Published: June 2022

AbstractWe provide a systematic literature review of the determinants and consequences of real earnings management (REM) in an international context. We provide a theoretical framework for REM, the development of REM measures, and review the determinants of REM, categorising these into financial reporting, auditing, governance and controls, capital market incentives, and regulatory determinants. We then review the empirical literature on the consequences of REM. We provide some suggestions for future research on measurement issues related to REM, and on filling gaps in the empirical research investigating its determinants and consequences.
Difference of opinion among investors versus analysts
Authors: Cao Zhiqi , Wu Wenfeng 
Published: June 2022

AbstractWe construct an investor‐based measure of differences of opinion (DO) to investigate the different implications of DO between retail investors (DOR), institutional investors (DOI), and analysts (DOA) on asset pricing. Using Chinese stock data, we find that three DO measures (DOR, DOI, and DOI) are negatively related to future returns; DOI’s ability to predict returns can be partly explained by DOR and DOA, whereas DOR contains incremental information not available from DOI and DOA. DOR is more strongly associated with the severe overvaluation caused by retail investors’ optimism than DOI or DOA, emphasising the specific role of retail investors in China’s market. We further show that DOI and DOA are the results of the differences in their information sets, whereas DOR are the results of different interpretations of public information.
Altered vitamin D metabolism is involved in the dysregulation of γδT cell function and their crosstalk with trophoblasts in recurrent pregnancy loss
Authors: Xu Qian‐Han , Muyayalo Kahindo P. , Zhang Yu‐Jing , Wang Huan , Lin Xin‐Xiu , Liao Ai‐Hua 
Published: June 2022

AbstractBackgroundRecurrent pregnancy loss (RPL) is a common disease characterized by immune dysfunction and vitamin D deficiency. This study aimed to investigate vitamin D metabolism and γδT cell phenotypes at the maternal–fetal interface in women with early normal pregnancy (NP) and RPL and to determine the effects of vitamin D on the functions of γδT cells and their crosstalk with trophoblasts.MethodsThe levels of 25‐(OH)VD3, the expression of vitamin D metabolic enzymes in the villi, and the proportion of γδT cells in the decidua were detected in women with NP and RPL. After treatment with different concentrations of vitamin D, the mRNA expression of the vitamin D receptor (VDR), cytokines, and transcription factors were detected in Vδ2+γδT cells. In addition, the proliferation, migration, and invasion of HTR‐8/SVneo trophoblasts were determined by coculturing them with vitamin D‐treated Vδ2+γδT cells and their supernatants.ResultsIn women with RPL, the level of 25‐(OH)VD3 in the villi was increased; however, that of CYP27B1 (enzyme converting 25‐(OH)VD3 into 1,25‐(OH)2VD3) was decreased. In addition, the proportion of Vδ2+γδT cells increased, whereas that of Foxp3+Vδ2+γδT cells decreased in the decidua of women with RPL. An in vitro study showed that vitamin D increased the expression of VDR mRNA and Foxp3, but decreased the expression of IFN‐γ mRNA, in Vδ2+γδT cells. Finally, vitamin D‐treated Vδ2+γδT cells promoted trophoblast migration and invasion.ConclusionsAbnormal vitamin D metabolism and γδT cell proportions were present at the maternal‐fetal interface in women with RPL. Under normal pregnancy conditions, vitamin D can induce the differentiation of decidual Vδ2+γδT cells toward an anti‐inflammatory phenotype (Treg‐like γδT cells) and modulate the crosstalk between Vδ2+γδT cells and trophoblasts.
Leveraging anthropological expertise to respond to the COVID‐19 global mental health syndemic
Authors: Azevedo Kathryn J. , Kalvesmaki Andrea F. , Riendeau Rachel P. , Sweet Philip A. , Holmes Seth M. 
Published: June 2022

AbstractThis commentary asks anthropologists to work within communities to actively address the global mental health impact of COVID‐19 and contribute to the pandemic response. Multiple social and physical losses, worsened by numerous factors, have produced syndemic traumatic stress and suffering across populations, highlighting persistent inequalities further amplified by the effects of COVID‐19. Specifically, anthropologists can work to contribute to the development of mental health programs; confront the racialization of COVID‐19 alongside marginalized communities; support real‐time policy making with community responses; and innovate transparent collaborative research methods through open science. This pandemic can serve as an opportunity to prioritize research endeavors, public service, and teaching to better align with societal needs while providing new opportunities for synergy and collaborations between anthropologists in and outside the academy. Anthropologists collaborating directly with mental health clinicians and the public can contribute to knowledge specifically through direct program development and implementation of interventions designed to improve mental well‐being. Innovating to find impactful solutions in response to the unprecedented mental health challenges exacerbated by the COVID‐19 pandemic has the potential to promote more equitable recovery around the world.
Influence of membership in outgroups varying in competence and warmth on observers' Level‐2 visual perspective taking
Authors: Vanbeneden Antoine , Woltin Karl‐Andrew , Yzerbyt Vincent 
Published: June 2022

AbstractVisual perspective taking (VPT), the ability to adopt another person's viewpoint, entails two distinct processes, Level‐1 (L1)‐VPT and Level‐2 (L2‐VPT), referring to the ability to perceive whether and how a target sees an object, respectively. Whereas previous efforts investigated the impact of targets' social characteristics on L1‐VPT, the present work is the first to do so regarding L2‐VPT. Specifically, we investigate the impact of targets' membership in outgroups varying in perceived competence and warmth, the two fundamental dimensions of social perception. Participants in four experiments engaged in a L2‐VPT task. Avatars belonged to a low competence low warmth group (LCLW; e.g. the homeless) or to a high competence low warmth group (HCLW; e.g. bankers) in Experiments 1–3, and to a LCLW or high competence high warmth group (HCHW; e.g. female students) in Experiment 4. Participants answered as quickly as possible whether a cued number matched a number present in a scene from either their own or the avatar's perspective. We consistently found support for the presence of both egocentric and altercentric interference, but this was not modulated by group competence and warmth, suggesting that membership in outgroups varying in competence and warmth does not influence L2‐VPT. We discuss the findings' implications in the light of recent views on VPT.

AbstractPatients suffering from immune‐mediated necrotizing myopathies (IMNM) harbor, the pathognomonic myositis‐specific auto‐antibodies anti‐SRP54 or ‐HMGCR, while about one third of them do not. Activation of chaperone‐assisted autophagy was described as being part of the molecular etiology of IMNM. Endoplasmic reticulum (ER)/sarcoplasmic reticulum (SR)‐stress accompanied by activation of the unfolded protein response (UPR) often precedes activation of the protein clearance machinery and represents a cellular defense mechanism toward restoration of proteostasis. Here, we show that ER/SR‐stress may be part of the molecular etiology of IMNM. To address this assumption, ER/SR‐stress related key players covering the three known branches (PERK‐mediated, IRE1‐mediated, and ATF6‐mediated) were investigated on both, the transcript and the protein levels utilizing 39 muscle biopsy specimens derived from IMNM‐patients. Our results demonstrate an activation of all three UPR‐branches in IMNM, which most likely precedes the activation of the protein clearance machinery. In detail, we identified increased phosphorylation of PERK and eIF2a along with increased expression and protein abundance of ATF4, all well‐documented characteristics for the activation of the UPR. Further, we identified increased general XBP1‐level, and elevated XBP1 protein levels. Additionally, our transcript studies revealed an increased ATF6‐expression, which was confirmed by immunostaining studies indicating a myonuclear translocation of the cleaved ATF6‐form toward the forced transcription of UPR‐related chaperones. In accordance with that, our data demonstrate an increase of downstream factors including ER/SR co‐chaperones and chaperones (e.g., SIL1) indicating an UPR‐activation on a broader level with no significant differences between seropositive and seronegative patients. Taken together, one might assume that UPR‐activation within muscle fibers might not only serve to restore protein homeostasis, but also enhance sarcolemmal presentation of proteins crucial for attracting immune cells. Since modulation of ER‐stress and UPR via application of chemical chaperones became a promising therapeutic treatment approach, our findings might represent the starting point for new interventional concepts.
