Published: November 2022

ABSTRACTPlant transpiration is controlled by stomata, with S- and R-type anion channels playing key roles in guard cell action. Arabidopsis mutants lacking the ALMT12/QUAC1 R-type anion channel function in guard cells show only a partial reduction in R-type channel currents. To identify the molecular nature of the remaining R-type anion channel population, patch clamp studies were performed. This R-type current fraction in thealmt12mutant exhibited the same voltage dependence, susceptibility to ATP block and lacked a chloride permeability as the wildtype. Therefore, we asked whether the R-type anion currents in the ALMT12/QUAC1-free mutant are caused by additional ALMT isoforms. In wildtype guard cellsALMT12, ALMT13andALMT14transcripts were detected, whereas only ALMT13 was found expressed in thealmt12mutant. Substantial R-type anion currents still remained active in thealmt12/13andalmt12/14double mutants as well as thealmt12/13/14triple mutant. This situation, supported by transpiration measurements, suggests that, with the exception of ALMT12, channel species other than ALMTs carry the guard cell R-type anion currents.

ABSTRACTThe interaction of T-cell receptors with peptide-major histocompatibility complex molecules plays a crucial role in adaptive immune responses. Currently there are various models aiming at predicting TCR-pMHC binding, while a standard dataset and procedure to compare the performance of these approaches is still missing. In this work we provide a general method for data collection, preprocessing, splitting and generation of negative examples, as well as comprehensive datasets to compare TCR-pMHC prediction models. We collected, harmonized, and merged all the major publicly available TCR-pMHC binding data and compared the performance of five state-of-the-art deep learning models (TITAN, NetTCR, ERGO, DLpTCR and ImRex) using this data. Our performance evaluation focuses on two scenarios: 1) different splitting methods for generating training and testing data to assess model generalization and 2) different data versions that vary in size and peptide imbalance to assess model robustness. Our results indicate that the five contemporary models do not generalize to peptides that have not been in the training set. We can also show that model performance is strongly dependent on the data balance and size, which indicates a relatively low model robustness. These results suggest that TCR-pMHC binding prediction remains highly challenging and requires further high quality data and novel algorithmic approaches.

Published: November 2022

AbstractWe present an analysis of the spatiotemporal dynamics of the oscillations in the electric potential that arises from neural activity. Depending on the frequency and phase of oscillations, these dynamics can be characterized as standing waves or as out-of-phase and modulated waves, which represent a combination of standing and moving waves. We characterize these dynamics as optical flow patterns, in terms of sources, sinks, spirals and saddles. Analytical and numerical solutions are compared with real EEG data acquired during a picture-naming task. Analytical approximation of standing waves allows us to establish some properties of pattern location and number. Namely, sources and sinks have mainly the same location, while saddles are located between them. The number of saddles correlates with the sum of all the other patterns. These properties are confirmed in both the simulated and real EEG data.

Published: November 2022

AbstractModerate levels of synchronization of neuronal oscillations are essential for healthy brain dynamics. Synchronization levels exhibit large inter-individual variability the origins of which are unknown. Neuronal systems have been postulated to operate near a critical transition point or in an extended regime between disorder (subcritical) and order (supercritical phase) characterized by moderate synchronization and emergent power-law long-range temporal correlations (LRTCs). We investigated whether inter-individual variability in synchronization levels is explained by the individual position along the critical regime by analyzing magnetoencephalography (MEG) and intra-cerebral stereo-electroencephalography (SEEG) human resting-state data. Here we show that variability in synchronization levels exhibits a positive linear and quadratic relationships with LRTCs in healthy participants and brain areas. In the epileptogenic zone this correlation was negative. These results show that variability in synchronization levels is regulated by the individual position along an extended critical-like regime, with healthy brain areas tending to operate in its subcritical and epileptogenic areas in its supercritical side.
Expanding branding: effects of multiple brand types on organizational attractiveness
Authors: Wu Lusi , Dineen Brian R. 
Published: November 2022

PurposeThis study aims to examine the relative effects of three organizational brand types (product, employment and corporate social responsibility brands) on organizational attractiveness. The potential differences in the impacts exerted by each brand on organizational attractiveness between the US and Chinese job seekers are also examined.Design/methodology/approachA policy-capturing design was used among both US and Chinese participants to test the hypothesized relationships using multilevel modeling.FindingsResults suggest that each brand type independently contributes to the prediction of attractiveness, with the employment brand a significantly stronger predictor than the other two. Besides, the strength of relationships between brands and organizational attractiveness varies among job seekers from different national contexts.Originality/valueThe findings contribute to the limited understanding of how different types of brands together influence organizational attractiveness among job seekers, and the role national context plays in it.
COVID and challenges in the context of family firms internationalisation: a review and emerging research pathways
Authors: Kampouri Katerina , Hajidimitriou Yannis 
Published: November 2022

Purpose
This study aims to fulfil a twofold purpose: first, to discuss the changes and unique challenges that family firms (FFs) face during the COVID-19 pandemic and/or they will face in the post-COVID era, and second, to reflect on emerging research directions and contextual factors that should be taken into account in future explorations for the benefit of FF scholars who will study post-COVID FF internationalisation.

Design/methodology/approach
To address the twofold purpose of the study, we conduct an integrative review of 31 peer-reviewed journal articles in the international business (IB) and FF literature on COVID-19, FFs and internationalisation.

Findings
COVID-19 brought changes in IB strategies, IB relationships and human resource management. In responding and/or adapting to those changes, during and post-COVID, FFs face and are expected to face challenges that mainly refer to FFs’ transition to digitalisation and the simultaneous preservation of socio-emotional wealth dimensions while maintaining their international presence. The authors suggest that future research explores the role of digitalisation in achieving FFs’ internationalisation, IB relationship building activities and training and leading international employees. Further contextual factors (e.g. succession issues, family structures) should also be accounted for when exploring such post-COVID IB phenomena.

Originality/value
This study comprises an initial attempt to encompass the interface of FF internationalisation and COVID-19. It also proposes research directions that are likely to set the stage in FFs’ post-COVID internationalisation research.
Greenfluencers as agents of social change: the effectiveness of sponsored messages in driving sustainable consumption
Authors: Kapoor Payal S. , Balaji M.S. , Jiang Yangyang 
Published: November 2022

Purpose
This study aims to examine the role of message appeals (concrete vs abstract) posted by greenfluencers in determining their behavioral intention toward the sponsored sustainable product. This study examined the underlying mechanism of message authenticity and product sustainability image in this relationship. This study also investigated the boundary condition of product type (utilitarian vs hedonic) in the effect of sustainability message appeal on purchase intention.

Design/methodology/approach
Four studies were carried out. One field experiment on Facebook and three scenario-based online experiments were conducted to test the proposed relationships.

Findings
This study found that a concrete message appeal results in a higher purchase intention of the promoted product than an abstract message appeal. This effect is a result of message authenticity and product sustainability image. Furthermore, product type moderates the impact of message appeal on behavioral intention via message authenticity and product sustainability image.

Research limitations/implications
This study contributes to the literature on influencer marketing, sustainability communication and the persuasion process.

Practical implications
This study’s findings provide insights for greenfluencers and firms that leverage greenfluencers to promote their sustainable products on social media. Specifically, it lays out how the sustainability message should be framed to be persuasive.

Originality/value
This study findings offer novel insights for greenfluencers and firms in developing effective message strategies to promote sustainable products on social media.

Published: November 2022

Purpose
A proliferation of articles surrounding the COVID-19 pandemic is calling for new insights through review. This paper aims to bibliometrically analyze the current progress of research around hospitality and tourism to define the research directions on herd immunity and the prevention of disease under the “new normal.”

Design/methodology/approach
This paper analyzed 326 articles regarding COVID-19 published in SSCI hospitality, leisure and tourism journals in 2020 and 2021 by combining manual analysis and bibliometrics to reveal research topics and to gain insight into research structures.

Findings
The results of this paper summarized topics related to stakeholders’ mentality and behavior, responses of travel suppliers to the COVID-19 pandemic, economic impact and demand forecasting, social issues of human rights and racism and reflection on tourism and transformation of the industry. More research is called for in the future to focus on a better response to the crisis, including crisis management education and training and the improving the resilience of small- and medium-sized enterprises.

Research limitations/implications
A three-dimensional consideration was proposed to promote the sustainable development of hospitality and tourism.

Originality/value
In the “new normal” phase of herd immunity and disease prevention, to the best of the authors’ knowledge, this is the first paper that provides an up-to-date systematic overview of the evolution of COVID-19 research in tourism and hospitality and encourages more conceptual, practical and futuristic studies.

Published: November 2022

PurposeRates of self-harm are elevated in prison, and there is limited evidence to support the efficacy of brief risk screening at reception to predict and prevent self-harm. This study aims to examine the predictive validity of the self-harm/suicide screening items embedded in a prison mental health screening tool from two key domains strongly associated with risk: previous suicidal/self-harm behaviour, and recent ideation.Design/methodology/approachA sample of men and women were screened on entry to prison, with eight screening items covering the two key domains of risk. Follow-up data on self-harm incidents were collected for 12 months post-screening. The predictive validity of individual screening items, item combinations and cumulative screening score was examined for the overall sample and for men and women separately.FindingsIndividual screening items across the two domains were all strongly associated with self-harm in the follow-up period, with odds ratios varying from 2.34 to 9.24. The predictive validity of both individual items, item scores and item combinations demonstrated high specificity but low to moderate sensitivity, and modest area under the curves (AUCs). Predictive validity was generally better for men than women; however, differences were not statistically significant.Practical implicationsIdentifying those at risk of self-harm in prisons remains challenging and brief universal screening at prison entry should be only one component of a broader prison risk assessment and management strategy.Originality/valueTo the best of the authors’ knowledge, this study is one of very few to prospectively examine self-harm behaviour following risk screening. Predictive validity was examined in a representative sample of individuals in custody, and for men and women separately.
Possible futures of crowd logistics for manufacturers: results of a strategic foresight study
Authors: Michel Sophie , Bootz Jean-Philippe , Bessouat Jeanne 
Published: November 2022

Purpose
Although crowd logistics (CL) is a promising digital solution, its future development remains uncertain. This paper aims to suggest multiple possible futures of CL in terms of business relationships and value co-creation between manufacturers and digital platforms.

Design/methodology/approach
This paper offers a systemic and multistakeholder approach related to the field of strategic foresight, based on the scenario method. The scenarios construction involved 22 participants (practitioners, academic researchers and foresight experts).

Findings
Four scenarios emerged from the strategic foresight study. For each scenario, the configuration, diffusion and coordination of CL – as well as the balance of power between manufacturers, digital platforms and customers – are specified.

Research limitations/implications
The foresight analysis reveals not one certain future, but multiple potential business configurations and research avenues related to the development of CL.

Practical implications
The adopted multistakeholders perspective, including macro factors, regarding CL allows business-to-business (B2B) managers to rethink its potential. Managers can use the scenarios to consider multiple types of coordination with digital platforms and its implication for value co-creation.

Social implications
This paper provides insights into social changes that may constitute drivers and consequences of the development of CL and identifies two forms of coupling that may drive the development of CL: regulation–social transformation and technology–environment.

Originality/value
This research contributes to IMP research on B2B relationships in digital contexts, by showing that CL presents an opportunity for the co-creation of distribution value in a B2B environment.

Understanding relationship marketing strategy in Ghana’s informal economy: a case of micro, small and medium enterprises
Authors: Adom Kwame , Tettey Louis Numelio , Acheampong George 
Published: November 2022

Purpose
Relationship marketing (RM) has rarely been applied to micro-, small- and medium-sized enterprises (MSMEs) in the informal economy (IE). Thus, this study aims to explore the RM strategy of service rendering micro-enterprises in the IE of a sub-Saharan African country like Ghana.

Design/methodology/approach
This study used a qualitative research approach using a multiple case study design, semi-structured interview and a random sampling technique to sample 15 micro-enterprises. Thereafter, the case was analysed thematically.

Findings
Results show that micro-enterprises in the IE engage in multiple dimensions of RM in their line of business. Also, micro-enterprises in the IE perceived RM as customer care and somewhat their standard of RM benefits measurement are different from those firms in the formal sector. Furthermore, micro-enterprises in the IE face challenges such as high resource commitment, harassment and the technological gap in practising their RM strategy.

Practical implications
MSMEs in the IE should develop a framework to minimise the shortfall of the challenges associated with RM implementation for business continuity and growth because customers are the lifeblood of the business.

Originality/value
To the best of the authors’ knowledge, this is the first known study that looks at RM practices of MSMEs in the IE. It has thrown light on the understudied subject of RM in MSMEs. For micro-enterprises operating in the Ghanaian IE, the benefits to be derived from practising RM are rewarding. The adopted qualitative methodology has provided an in-depth insight into a vital area for both academics and practitioners.
Competitive rivalry in the digital market: an action-configuration perspective
Authors: Qi Hui , Yao Xiaotao , Fan Weiguo 
Published: November 2022

PurposeThe purpose of this paper is to explore the nature of a competitive action and its impact on the response of rivals in the digital market. Specifically, this paper introduces the concept of action complexity and action variation to delineate the configuration characteristics of each digital competitive action and empirically investigates how these action characteristics further affect rivals’ response speed.Design/methodology/approachThis paper uses structural content analysis methods to code competitive actions based on the news of Chinese online travel agencies (OTAs) from 2010 to 2015. The cox proportional hazards regression models are employed to test the hypotheses.FindingsThe results indicate that action complexity of the focal firm is negatively associated with rivals’ response speed as it constrains their interpretation (awareness), motivation and capability to respond, while action variation of the focal firm is positively associated with rivals’ response speed as it enhances their attention (awareness) and motivation to respond. Furthermore, the negative relationship between action complexity and response speed is weaker when action variation is high.Originality/valueFurther to advancing competitive dynamics theory, this paper proposes an action-configuration perspective to explore the particular content and quality of each digital competitive action. The discussion of competitive rivalry between OTAs also enriches the application of competitive dynamics in the digital market. Meanwhile, this paper further clarifies the decision-making process of rivalry drawing on the awareness–motivation–capability (AMC) framework.

Authors: Açar Yasemin , Yıldıran Hilal 
Published: November 2022

Purpose
This study aims to evaluate the reflection of COVID-19 pandemic anxiety experienced in adults on nutritional habits during the COVID-19 pandemic in Turkey.

Design/methodology/approach
The study was conducted with 600 adults aged between 19 and 64 years. The general characteristics of the individuals, nutritional habits, use of dietary supplements and COVID-19 pandemic anxiety before and during the pandemic period were questioned via a Web-based questionnaire. COVID-19-related anxiety was assessed using The COVID-19 Phobia Scale (C19P-S) and The State-Trait Anxiety Inventory (STAI). Data analysis was performed using the Statistical Package for Social Sciences, version 24.0.

Findings
In this study, 49.8% of the participants stated that their appetite and food consumption amount increased during the pandemic period. The rate of use of dietary supplements among individuals was found to be 40%. It was observed that the mean body weight and body mass index increased significantly in both genders during the COVID-19 pandemic. It has been determined that anxiety about COVID-19 is higher in individuals and women who start using nutritional support during the pandemic period. The total C19P-S and STAI scores of those who started using a dietary supplement during the pandemic were significantly higher than those who did not use a dietary supplement. Similarly, those whose eating habits changed positively and those who bought more packaged products had higher C19P-S scale mean scores (p < 0.05).

Originality/value
During the COVID-19 period, it is important to reduce the anxiety levels of individuals, provide psychological support, raise awareness of adequate and balanced nutrition and the correct use of dietary supplements to adapt to the new lifestyle.
