Revealing mission statements in a hotel brand sector using social network analytic approach
Authors: Breznik Kristijan , Zupan Korže Saša , Ragozini Giancarlo , Gorenak Mitja 
Published: December 2022

Purpose
This study aims to investigate the content of hotel brands’ mission statements (MSs) and their relationship with selected attributes of hotel brands.

Design/methodology/approach
Content analysis of hotel brands’ MSs was used to detect the MSs’ key words, which were further processed by methods of social network analysis, complemented by clustering techniques and correspondence analysis on the generalized aggregated lexical tables, a special type of correspondence analysis.

Findings
Hotel brands operating in luxurious markets more often emphasize experiences than those in midscale markets. Furthermore, hotel brands with longer traditions and those with a large number of controlled rooms communicate words in their MSs that represent a rather traditional approach to hospitality. Younger hotel brands with fewer controlled rooms chose words that indicate a more commercially oriented approach. Finally, cluster analysis revealed four dimensions of hotel brands’ MSs, instead of the nine most typically used in mission statement component models.

Practical implications
Understanding the frequencies and networks of keywords, and their relationship with hotel brand attributes, will help create more focussed MSs. This will strengthen hotel brands, raise their revenues and subsequently increase company performance.

Originality/value
The analysis provides valuable insight into MSs in the specific tourism context of hotel brands. The authors have achieved this with the use of a wide range of advanced network analytic methods. These insights can guide hotel brands to better position themselves in the competitive tourism accommodation market.
A novel residual shrinkage block-based convolutional neural network for improving the recognition of motor imagery EEG signals
Authors: Huang Jinchao 
Published: December 2022

PurposeRecently, the convolutional neural network (ConvNet) has a wide application in the classification of motor imagery EEG signals. However, the low signal-to-noise electroencephalogram (EEG) signals are collected under the interference of noises. However, the conventional ConvNet model cannot directly solve this problem. This study aims to discuss the aforementioned issues.Design/methodology/approachTo solve this problem, this paper adopted a novel residual shrinkage block (RSB) to construct the ConvNet model (RSBConvNet). During the feature extraction from EEG signals, the proposed RSBConvNet prevented the noise component in EEG signals, and improved the classification accuracy of motor imagery. In the construction of RSBConvNet, the author applied the soft thresholding strategy to prevent the non-related motor imagery features in EEG signals. The soft thresholding was inserted into the residual block (RB), and the suitable threshold for the current EEG signals distribution can be learned by minimizing the loss function. Therefore, during the feature extraction of motor imagery, the proposed RSBConvNet de-noised the EEG signals and improved the discriminative of classification features.FindingsComparative experiments and ablation studies were done on two public benchmark datasets. Compared with conventional ConvNet models, the proposed RSBConvNet model has obvious improvements in motor imagery classification accuracy and Kappa coefficient. Ablation studies have also shown the de-noised abilities of the RSBConvNet model. Moreover, different parameters and computational methods of the RSBConvNet model have been tested on the classification of motor imagery.Originality/valueBased on the experimental results, the RSBConvNet constructed in this paper has an excellent recognition accuracy of MI-BCI, which can be used for further applications for the online MI-BCI.
Impact of fake news on firm performance during COVID-19: an assessment of moderated serial mediation using PLS-SEM

Published: December 2022

PurposeFake news on social media about COVID-19 pandemic and its associated issues (e.g. lockdown) caused public panic that lead to supply chain (SC) disruptions, which eventually affect firm performance. The purpose of this study is to understand how social media fake news effects firm performance, and how to mitigate such effects.Design/methodology/approachGrounded on dynamic capability view (DCV), this study suggests that social media fake news effects firm performance via SC disruption (SCD) and SC resilience (SCR). Moreover, the relation between SCD and SCR is contingent upon SC learning (SCL) – a moderated mediation effect. To validate this complex model, the authors suggest effectiveness of using partial least squares structural equation modeling (PLS-SEM). Using an online survey, the results support the authors’ hypotheses.FindingsThe results suggest that social media fake news does not affect firm performance directly. However, the authors’ serial mediation test confirms that SCD and SCR sequentially mediate the relationship between social media fake news and firm performance. In addition, a moderated serial mediation test confirms that a higher level of SCL strengthens the SCD–SCR relationship.Research limitations/implicationsThis work offers a new theoretical and managerial perspective to understand the effect of fake news on firm performance, in the context of crises, e.g. COVID-19. In addition, this study offers the advancement of PLS as more robust for real-world applications and more advantageous when models are complex.Originality/valuePrior studies in the SC and marketing domain suggest different effects of social media fake news on consumer behavior (e.g. panic buying) and SCD, respectively. This current study is a unique effort that investigates the ultimate effect of fake news on firm performance with complex causal relationships via SCD, SCR and SCL.
Understanding lurking behavior on enterprise social media: the perspective of the transactional model of stress
Authors: Yuan Qin , Liu Chun 
Published: December 2022

PurposeDrawing on the transactional model of stress, this study develops a theoretical model to understand the lurking behavior on enterprise social media (ESM).Design/methodology/approachBased on a questionnaire survey, this research study collected valid data from 301 ESM users in the workplace. Hierarchical regression analyses are used to analyze the conceptual framework.FindingsThe results show that Zhongyong thinking is a significant predictor of lurking and emotional exhaustion and that lurking can cause emotional exhaustion. Lurking mediates the relationship between Zhongyong thinking and emotional exhaustion. Additionally, communication overload moderates the relationship between lurking and emotional exhaustion as well as the indirect relationship between Zhongyong thinking and emotional exhaustion through lurking.Originality/valueThis article examines the antecedents of lurking by considering Zhongyong thinking and explores how lurking on ESM influences emotional exhaustion. This research contributes to the literature on techno-stressors, lurking and ESM and hopefully contributes to the growing dialog about the consequences of lurking in the workplace.
Managing tensions in resilience development: a paradox theory perspective on the role of digital transformation
Authors: Mishra Ruchi , Singh Rajesh Kr , Song Malin 
Published: December 2022

PurposeThe study aims to identify the central paradoxical tensions existing in developing resilience in organisations. The main thrust of this study is to develop a thorough understanding of diverse conflicting tensions in building resilience and develop the possible strategies to surmount these tensions.Design/methodology/approachUsing the case study approach, the study applied theory-elaboration strategy as this study is based on well-established literature from both digitalisation and resilience. The study uses the paradox theory lens in a case study to reconcile both theories with contextual idiosyncrasies.FindingsThe paradox theory lens provides perspectives to understand tensions during resilience development and the role of digital transformation in this process. It assesses the potential solutions for surmounting tensions in resilient operations. The mapping of workable solutions with different paradoxes and propositions has been proposed for future empirical research.Research limitations/implicationsThe study suggests that practitioners should not consider resilience and sustainability as mutually exclusive; instead, managers must embrace ongoing tensions to bring solutions to address these two essential organisational priorities.Originality/valueTo the best of the authors' knowledge, this is the first empirical study that applies paradox theory to understand how an organisation can build resilience while confronting several paradoxes. The study findings support that resilience practices can move in tandem with environmental sustainability goals rather than being usually mutually exclusive.
The competition-cooperation interplay for knowledge development: a headquarters-subsidiary perspective
Authors: Lagerström Katarina , Leite Emilene , Pahlberg Cecilia , Schweizer Roger 
Published: December 2022

PurposeIn this paper, the authors contribute with insights on competition and cooperation in multinational enterprises with a focus on challenges related to these governance mechanisms in a knowledge development context. The mechanisms have been widely recognized as important for developing knowledge, but their contradicting nature implies considerable complexity when it comes to governance. The complexity is further increased as a result of the headquarters-subsidiary relationships. The aim of this paper is to contribute with theoretical and empirical insights on these aspects by focusing on the research question: How and why does competition and cooperation in an MNE emerge over time?Design/methodology/approachA manufacturing MNE with headquarters (HQ) in Sweden is analyzed on both HQ and subsidiary levels. Interviews with 24 managers in Sweden and India have been performed.FindingsThe study illustrates that competition and cooperation are integral aspects in HQ-subsidiary relationships. The results show that both competition and cooperation depend on environmental, organizational and object-related conditions and that these conditions influence the dynamics of the interplay. The importance of including a subsidiary perspective and the interdependencies in an MNE setting are emphasized.Originality/valueThe authors add to the discussion on the interplay between competition and cooperation as they play an important role for knowledge development in MNEs. The results indicate that they do not take place simultaneously, and therefore, the authors suggest that the dynamic can be better understood by focusing on the interplay and analyze the concepts separately.
Involved at work and disinvolved out of work: unraveling the implications of involvement on accountants' work–life balance
Authors: Palumbo Rocco 
Published: December 2022

PurposeBeing involved at work advances accountants' contribution to organizational success. However, scholars are not consistent in discussing involvement's implications on work–life balance (WLB). The article aims to address this issue, investigating involvement's effects on the accountants' ability to manage the work–life interplay.Design/methodology/approachSecondary data on a sample of 538 accountants were collected from the sixth European Working Condition Survey (EWCS). A serial mediation analysis was designed to obtain evidence of involvement's implications on WLB through the mediating role of work engagement and work satisfaction.FindingsInvolvement negatively affected the accountants' ability to deal with the work–life interplay. Engagement and satisfaction with work mediated this relationship. More specifically, involved accountants who were engaged and satisfied with their work conditions were less likely to report struggles between work and life.Research limitations/implicationsInvolvement implies an intensification of work, heralding an overlapping between work and life. Nonetheless, accountants who are engaged and satisfied with work are less touched by involvement's drawback on WLB. A precautionary approach should be taken to avoid that involvement results in workaholism, thus undermining individual well-being.Originality/valueThe article originally discusses involvement's implications on WLB across accountants. Being involved at work impairs the individual ability to achieve a balance between work and life, endangering well-being at work. Whilst the findings cannot be generalized beyond the accounting profession, they deliver some intriguing insights that highlight avenues for further developments.
Does cost-inefficiency in Islamic banking matter for earnings uncertainty?
Authors: Boubaker Sabri , Uddin Md Hamid , Kabir Sarkar Humayun , Mollah Sabur 
Published: December 2022

Purpose
This paper aims to investigate a fundamental research question of whether the Islamic banking business model makes corporate earnings more uncertain. This question arises because prior research shows that Islamic banks do well in loan performance but incur more operational costs than conventional banks, indicating the systemic limitation of Islamic banks in business risk management.

Design/methodology/approach
The study used a sample of banks to conduct the panel regression analysis with 15 years of data for 532 banks (129 Islamic and 403 conventional) from 23 Muslim countries across the world. The authors estimate earnings uncertainty in two ways: the spread and standard deviation of the country-adjusted return over the sample period and applied the difference-in-difference approach interacting cost to income ratio with the Islamic bank dummy, checking if Islamic bank’s high operational costs contribute to more earning uncertainty.

Findings
Islamic banks’ returns on assets are significantly more uncertain than conventional banks due to higher operational costs. Consistent with earlier evidence, the study also finds that Islamic banks generally have fewer nonperforming loans than conventional banks. The authors conclude that Islamic banks trade-off between reducing credit risk and escalating business risk.

Originality/value
This study documents that the Islamic banking model helps build a safer asset portfolio but gives rise to the uncertainty of corporate earnings. Therefore, the choice between Islamic and conventional banking models involves a trade-off between credit and business risks. It is a new finding that we add to the literature body on Islamic finance.
Compliance and obedience in an Alabama prison faith dorm
Authors: Thornton Thomas 
Published: December 2022

AbstractThis article considers how the Christian obedience of male prisoners inside the ‘faith dorm’ of a maximum‐security prison in the US state of Alabama overlaps with penal compliance. I argue that prisoners’ devotion to faith‐dorm strictures is not straightforward rule‐following but forges social and Christly intimacy. Faith‐dorm obedience foregrounds the theological, and it reveals non‐church institutional domains as theologically dynamic and capable of spiritually infused material work. To explore this, I describe how spiritual governance became a technique of Alabama's prison population management. Then I show how the resulting compliance is transfigured into critical notions of obedience that elicit practices of care and mutual support among prisoners through theological imaginaries of grace and Jesus’ crucifixion. Ultimately, I advance prisoners’ obedience as ‘dark wisdom’, which draws on the paradox of a crucified messiah to derive justice and intimacy from the prison's coerced living conditions.
Opportunities of online analysis1
Authors: Niesser Arthur 
Published: December 2022

AbstractThe question of whether tele‐analysis is an acceptable way of conducting analysis has been discussed since it has become available. Merchant (2016) and others concluded that ‘the essentials of a genuine analytic process are not necessarily precluded’ (p. 1). In this paper, the author goes a step further and examines potential advantages of tele‐analysis. There may be benefits for patients with a history of physical or sexual abuse who value the distance. The potential for a ‘safe place’ for work with erotic transference is also examined. In a further section the author is interested in allowing the analyst the freedom to practise in an authentic way, congruent with their personality. Also explored is the concept of the interactive field including the technological medium, which is subject to synchronistic events. Finally, the author gives examples of a deep connection between patient and analyst which came about despite the physical distance.
Alternative splicing of POUM2 regulates embryonic cuticular formation and tanning in Bombyx mori

Published: December 2022

AbstractInsect cuticle is an apical extracellular matrix produced by the epidermis, tracheal, hind‐ and foregut epithelia during embryogenesis and renewed during molting and metamorphosis. However, the underlying regulatory mechanism for embryonic cuticle formation remains largely unclear. Here, we investigate the function of the transcription factor POUM2 in the embryonic cuticular formation in Bombyx mori, a model lepidopteran insect. Clustered regularly interspaced palindromic repeats (CRISPR)/CRISPR‐associated protein‐9‐mediated knockout of POUM2 resulted in the defect of cuticular deposition, pigmentation, and sclerotization in the embryos. Differentially expressed transcripts analysis of 7‐d‐old embryos identified 174 up‐ or downregulated cuticular protein transcripts, 8 upregulated chitin degradation transcripts, 2 downregulated chitin synthesis transcripts and 48 up‐ or downregulated transcription factor transcripts in the POUM2−/− embryos. The expression levels of the key factors of the tyrosine metabolic pathway, such as tyrosine hydroxylase (Th), Dopa decarboxylase (DDC), and arylalkylamine N‐acetyltransferase (aaNAT), were significantly decreased in the POUM2−/− embryos. POUM2 isoform POUM2‐L specifically bound the POU cis‐regulatory element (CRE) in the Th promoter and increased the transcription of Th, whereas POUM2‐S could not bind the POU CRE, although it also increased the transcription of Th. Heterogeneous nuclear ribonucleoprotein Squid‐1 directly bound the POUM2 pre‐mRNA (messenger RNA) and inhibited the alternative splicing of POUM2‐L to POUM2‐S mRNA. These results suggest that POUM2 participates in the cuticular formation by regulating the chitin and cuticular protein synthesis and metabolism, and the cuticular pigmentation and sclerotization by regulating tyrosine metabolism during embryogenesis. This study provides new insights into novel function of POUM2 in embryogenesis.
Edema localized to the lips as a novel manifestation of myositis
Authors: Sumida Hayakazu , Asano Yoshihide , Shimizu Jun , Sato Shinichi 
Published: December 2022

AbstractPolymyositis (PM) and dermatomyositis (DM) are idiopathic inflammatory myopathies with presumed autoimmune pathogenesis, characterized by the features of proximal skeletal muscle weakness and evidence of muscle inflammation. Skin manifestations usually prompt earlier recognition and diagnosis of DM than PM, which has no rash. Associated delayed diagnosis and treatment in PM lead to worse outcomes. Therefore, an accumulation of case reports regarding initial symptoms suggestive of PM has been required to obtain an earlier diagnosis and better clinical outcomes in PM patients. We herein report a PM patient with an unusual presentation of edema restricted to the lips, which was clinically suggestive of granulomatous cheilitis but histologically verified as a manifestation of myositis. In this patient, no myositis‐specific antibodies including anti‐nuclear matrix protein 2 antibodies, were detected, and histological analysis on the muscle biopsy specimen revealed CD4‐dominant lymphocyte infiltration but no C5b‐9 deposition nor myxovirus resistance protein A expression. Further analysis with MRI (magnetic resonance imaging) scan of the lips showed increased signal intensity in the muscle layer on short TI inversion recovery images, and these suggest the potential of MRI as a useful tool for exploring the inflammatory site and the possibility of myositis in swollen lips. Thus, our report indicates the importance of suspecting myositis in the case of unusual edema restricted to the lips.
A novel drainage strategy using chest tube plus pleural catheter in uniportal upper lobectomy: A randomized controlled trial

Published: December 2022

AbstractBackgroundIn this study we explored whether one pleural catheter plus single chest tube drainage could achieve a noninferior drainage effect when compared with the traditional two chest tubes in uniportal video‐assisted thoracoscopic surgery (VATS) for an upper pulmonary lobectomy.MethodsPatients that underwent an upper pulmonary lobectomy from January to November 2020 were enrolled in this single‐center, randomized, open‐label, noninferiority trial. Prior to closure, patients were randomized to an intervention group who received an improved drainage strategy involving one pleural catheter with one chest tube (24 Fr), while traditional double chest tube drainage was applied for the control group.ResultsA total of 390 patients entered the study, although 190 were excluded for changing nonuniportal surgical approaches or opting for nonlobectomy resections. Finally, 200 patients were randomized (100 in the intervention group and 100 in the control group). The baseline demographic and clinical characteristics were comparable between the groups. The incidence of pneumothorax in the intervention and control groups was similar on postoperative Day 1 (noninferiority, 10% vs. 13%, p = 0.658). In addition, there were no significant differences in secondary outcomes such as incidence of pneumothorax by Day 30, postoperative chest tube/pleural catheter removal time, amount of drainage on Day 1, total amount of drainage after operation, or postoperative hospitalization. A significantly lower pain score was observed in the intervention group (3.33 ± 0.68 vs. 3.68 ± 0.94, p = 0.003).ConclusionsThe new strategy is noninferior to double chest tube drainage after an upper pulmonary lobectomy offers superior pain control, and is recommended for an upper lobectomy by uniportal VATS.
