AbstractDiffusion tensor imaging (DTI) aims to non-invasively characterize the anatomy and integrity of the brain’s white matter fibers. To establish individual-specific precision approaches for DTI, we defined its reliability and accuracy as a function of data quantity and analysis method, using both simulations and highly sampled individual-specific data (927-1442 diffusion weighted images [DWIs] per individual). DTI methods that allow for crossing fibers (BedpostX [BPX], Q-Ball Imaging [QBI]) estimated excess fibers when insufficient data was present and when the data did not match the model priors. To reduce such overfitting, we developed a novel crossing-fiber diffusion imaging method, Bayesian Multi-tensor Model-selection (BaMM), that is designed for high-quality repeated sampling data sets. BaMM was robust to overfitting, showing high reliability and the relatively best crossing-fiber accuracy with increasing amounts of diffusion data. Thus, the choice of diffusion imaging analysis method is important for the success of individual-specific diffusion imaging. Importantly, for potential clinical applications of individual-specific precision DTI, such as deep brain stimulation (DBS), other forms of neuromodulation or neurosurgical planning, the data quantities required to achieve DTI reliability are lower than for functional MRI measures.
Effect of membrane cholesterol on dynamical properties of solvent molecules
Authors: Rahmaninejad Hadi , Vaughan Darin D. 
Published: February 2021

AbstractMembrane lipid composition is a critical feature of cell function, where cholesterol is a major lipid sterol component that influences the membranes physical and electrical properties. The effects of cholesterol on transport properties between adjacent to the cells, especially in junctions formed between cells is not completely understood. These junctions where substances transport and signaling is critical may be affected by modifying the cholesterol composition of the membrane in these junctional regions. Here we show how the cholesterol content in a membrane can regulate these phenomena by changing their effect on transport into and through regions between cell membranes in close proximity. Through geometric and electrostatic effects interaction with substrates, the properties of the fluid between membranes are shown to potentially enforce concentration gradients of dissolved compounds that may be biologically significant.

Published: February 2021

Purpose
Employment can make an important contribution to individual well-being, for example, by providing people with a sense of purpose; however, autistic individuals face significant barriers to entering the workforce. This is reflected in high levels of underemployment and unemployment, with an estimated 80% of autistic people unemployed worldwide. This is higher than both other disability groups and people without disabilities. Research is needed to identify strategies that facilitate the sustained employment of autistic adults. This study aims to examine the perspectives of autistic individuals participating in a specialized employment program within the information and communication technology sector.

Design/methodology/approach
Three focus groups were conducted with nine adults on the autism spectrum. Data were analyzed using an inductive approach according to established guidelines, which included coding and categorizing data into themes.

Findings
Focus group analysis revealed four themes: trainees’ previous work experiences; expectations of the employment program; recruitment and selection processes; and training and transition. Several factors associated with the changes to the recruitment and selection process were found to benefit the autistic employees.

Originality/value
Few studies have characterized the work experiences of adults on the autism spectrum. Tailored employment processes that challenge traditional human resource management practices can increase the participation of autistic individuals in the workforce. Strategies for promoting the success of these programs are discussed.
A moderated mediation model of idiosyncratic deals and innovative performance of R&D employees: roles of vitality
Authors: Huang Yufang , Chen Xin 
Published: February 2021

PurposeAs personalized work arrangements, idiosyncratic deals can activate employees’ energy and thus affect their innovative performance. The purpose of this study was to examine whether employee vitality mediates the relationships between two different types of idiosyncratic deals and the innovative performance of employees and whether the mediating effects are moderated by employees’ age.Design/methodology/approachMatched data were collected from 620 employees and their direct supervisors who work in two large Chinese technology R&D organizations.FindingsResults indicate that two different types of i-deals (task and work responsibilities i-deals and flexibility i-deals) are positively related to the innovative performance of employees and that vitality mediates those relationships. Further, chronological age enhances the positive relationship between task and work responsibilities i-deals and vitality, and it enhances the indirect effect that task and work responsibilities i-deals relate to the innovative performance of employees through vitality. However, the results of this study indicate that the moderating effect of chronological age on flexibility i-deals and vitality, as well as the moderated mediation effects of vitality on the relationship between flexibility i-deals and the innovative performance of employees, did not meet the standard for significance.Originality/valueBased on the cognitive evaluation theory, this study explores more deeply the mechanism by which task and work responsibilities i-deals and flexibility i-deals activate employees’ energy and thus influence their innovative performance. In addition, this study comprehensively considers the moderating effect of chronological age, an important demographic variable, on the mechanism of idiosyncratic deals.

Published: February 2021

PurposeThe main purpose of this study is to investigate the impact of service robots on hotel visitors' behaviour and to verify the role of anthropomorphism(human likeness) in customer satisfaction with robots.Design/methodology/approachAn online survey of 381 respondents was conducted, divided into three types of robots according to the level of anthropomorphism. The research model was thoroughly tested using the PLS-SEM method. Research model was tested thoroughly using the PLS-SEM method.FindingsThis study found that user satisfaction with service robots in a hotel had a positive impact on user satisfaction, attitude towards the hotel and room purchase intention. Moreover, our results showed that users were most likely to accept medium-human likeness robots and least likely to accept high–human likeness robots.Originality/valueThis study proposes influencing factors to be considered when researching hotel service robots, as well as practical suggestions for any hotel intending to use or currently using a service robot.

Authors: Ruales Guzmán Bertha Viviana , Rodríguez Lozano Gloria Isabel , Castellanos Domínguez Oscar Fernando 
Published: February 2021

PurposeThis research had two main objectives: To measure the productivity of companies in the Colombian dairy industry and to identify efficient decision-making units (DMUs) that can be used as work sample in future case studies.Design/methodology/approachIn the measurement of productivity, financial variables were considered for a sample of 19 DMUs. Efficient companies were identified through the data envelopment analysis (DEAs) methodology with the VRS model oriented to inputs and outputs. The input variables analyzed were “current asset,” “property, plant and equipment,” “non-current liability” and “equity,” while the output variables were “revenue” and “profit.”FindingsFindings revealed that seven DMUs are efficient in the input and output orientation and that companies of different sizes and with or without quality certifications are efficient in the sample analyzed. Additionally, the benchmark efficient DMUs were identified for each of the non-efficient DMUs.Research limitations/implicationsThe implications for the research include the contribution to the theory, on the one hand, with the analysis of the current state of the literature on the use of DEA in the food sector, and on the other, with the use of DEA to measure the productivity of Colombian dairy industry companies and with the identification of a sample of efficient units that can be analyzed in future case studies.Originality/valueThis article is novel and pioneering because it measures for the first time the productivity of DMUs of the Colombian dairy industry, in addition to including the current state of the literature on the application of the DEA methodology in the food sector. These findings contribute to the consolidation of the theory and also provide inputs for researchers, practitioners, managers, and policy makers.

Authors: Lloyd Annemaree , Hicks Alison 
Published: February 2021

PurposeThe aim of this study is to investigate people's information practices as the SARS-CoV-2 virus took hold in the UK. Of particular interest is how people transition into newly created pandemic information environments and the ways information literacy practices come into view.Design/methodology/approachThe qualitative research design comprised one-to-one in-depth interviews conducted virtually towards the end of the UK's first lockdown phase in May–July 2020. Data were coded and analysed by the researchers using constant comparative and situated analysis techniques.FindingsTransition into new pandemic information environments was shaped by an unfolding phase, an intensification phase and a stable phase. Information literacy emerged as a form of safeguarding as participants engaged in information activities designed to mitigate health, legal, financial and well-being risks produced by the pandemic.Research limitations/implicationsTime constraints meant that the sample from the first phase of this study skewed female.Practical implicationsFindings establish foundational knowledge for public health and information professionals tasked with shaping public communication during times of crisis.Social implicationsThis paper contributes to understandings of the role that information and information literacy play within global and long-term crises.Originality/valueThis is one of the first studies to explore information practices during the COVID-19 pandemic.
The effect of change leadership on employee attitudinal support for planned organizational change
Authors: Onyeneke Gechinti Bede , Abe Tomokazu 
Published: February 2021

Purpose The purpose of this paper is to examine how change leadership activities help bring about employee support for planned organizational change.Design/methodology/approachUsing a non-experimental quantitative research design, and a self-administered Likert-type questionnaire survey, the study sourced data from employees in an organization undergoing significant change. Data analysis was by structural equation modeling (SEM).FindingsChange leadership behaviors bearing on; visioning, communication, participation, support and concern for change participants' interests were found to be of significant importance in ensuring employee buy-in and support for planned change efforts. Although change leadership had no direct effect on employees' behavioral intentions to support change, it was strongly related to employee cognitive appraisal of change. The relationship between change leadership and employee behavioral intentions to support planned change was serially mediated by employee cognitive appraisal and emotional response toward the planned change event.Practical implicationsIn appraising planned organizational change efforts, managers tend to focus on employee behaviors toward the change instead of conditions that drive such behaviors. This study underscores the need to focus on employee attitudes as precursors to desired behavior toward change.Originality/valuePrior research suggests that change leadership behaviors affect employee attitudinal reactions to change but yet lacked empirical validation. By applying a multidimensional approach to attitude and investigating its hierarchy of effects, this study enhanced our accuracy in explaining the influence change leadership has on employee attitudinal support for change.
Can tasks and learning be balanced? A dual-pathway model of cloud-based e-learning continuance intention and performance outcomes
Authors: Cheng Yung-Ming 
Published: February 2021

PurposeThe purpose of this paper is to examine the roles of task-technology fit (TTF), learning-technology fit (LTF) and cognitive absorption (CA) in determining medical professionals’ cloud-based electronic learning (e-learning) system continuance intention and performance outcomes and evaluate whether medical professionals’ perceived impact on learning can affect their perceived impact on tasks within medical institutions.Design/methodology/approachSample data for this study were collected from medical professionals at six hospitals in Taiwan. A total of 600 questionnaires were distributed, and 373 (62.2%) usable questionnaires were analyzed using structural equation modeling in this study.FindingsIn this study, medical professionals’ perceived TTF and LTF as antecedents to their cloud-based e-learning continuance intention and performance outcomes were validated, and medical professionals’ perceived impact on learning had a positive effect on their perceived impact on tasks. Synthetically speaking, this study’s results strongly support the research model with all hypothesized links being significant.Originality/valueIt is particularly worth mentioning that this study introduces a new construct, “LTF,” to conceptualize, define and measure it, and further contributes to the application of capturing both expectation–confirmation model and CA (i.e. an intrinsic motivator) for completely explaining medical professionals’ perceived TTF and LTF as external variables to their cloud-based e-learning continuance intention and performance outcomes.
Whatever happened to group dynamics in the scientific study of groups?
Authors: Schruijer Sandra G.L. 
Published: February 2021

Purpose
The purpose of this study is to explore whether a group dynamics perspective still exists in the scientific study of groups and what factors may account for the current situation.

Design/methodology/approach
Alongside reflections based on my professional experience, I have analyzed the main academic journals that publish group research.

Findings
A group dynamics perspective is almost totally absent in the scientific study of groups. Contributing factors to this state of affairs are disciplinary developments in psychology (e.g. individualization, experimentalization and specialization), the demise of the status of psychoanalysis, changes in the meaning and manifestation of the “group,” and effects of New Public Management.

Originality/value
The study offers a critical perspective on current group research practices and considers these in a larger (social and historical) context. It advocates a group dynamics perspective for the study of groups, based on systems-psychodynamic insights.
Clinical characteristics and outcomes of bullous pemphigoid patients with versus without oral prednisolone treatment

Published: February 2021

AbstractBullous pemphigoid (BP) varies in severity and stratified treatments are needed. However, there are no definitive standards for choosing appropriate treatments. To elucidate the factors involved in choosing treatments and the clinical outcomes of BP, we retrospectively reviewed the clinical records of 78 BP patients at a single center. Of the 78 patients, 49 (62.8%) were treated with oral prednisolone (PSL) and 29 (37.2%) were treated without PSL. The patients with older age, lower Bullous Pemphigoid Disease Area Index (BPDAI), and/or lower anti‐BP180NC16a antibody titer at onset tended to be treated without oral PSL. Notably, only 9.1% patients without PSL experienced relapse, whereas 36.7% patients with oral PSL experienced relapse when the PSL was around 0.1 mg/kg. It suggests that the patients with mild disease severity could be well controlled without oral PSL. Receiver–operator curve analysis demonstrated that the cut‐off value for the use of oral PSL was 31 for total BPDAI and was 7 for BPDAI skin urticaria/erythema, with a high (>0.9) area under the curve. Notably, none of the patients who were negative for the anti‐BP180NC16a antibody at onset experienced relapse even though they were treated without PSL. In conclusion, in BP patients who were negative for anti‐BP180NC16a antibody at onset, with a total BPDAI score of less than 31 or with an urticaria/erythema score of less than 7 can be treated without PSL. When the PSL is tapered to around 0.1 mg/kg, we should carefully monitor the patients to detect relapse.
Land cover, individual’s age and spatial sorting shape landscape resistance in the invasive frog Xenopus laevis
Authors: Vimercati Giovanni , Kruger Natasha , Secondi Jean 
Published: February 2021

Abstract

The description of functional connectivity is based on the quantification of landscape resistance, which represents species‐specific movement costs across landscape features. Connectivity models use these costs to identify movement corridors at both individual and population levels and provide management recommendations for populations of conservation interest. Typically, resistance costs assigned to specific land cover types are assumed to be valid for all individuals of the population. Little attention has been paid to intraspecific variation in resistance costs due to age or dispersal syndrome, which may significantly affect model predictions.

We quantified resistance costs in an expanding invasive population of the African clawed frog Xenopus laevis in Western France. In this principally aquatic amphibian, juveniles, sub‐adults and adults disperse overland. The enhancement of dispersal traits via spatial sorting has been also observed at the range periphery of the population. Resistance costs, and thus connectivity, might vary as a function of life stage and position within the invaded range.

We assessed multiple dimensions of functional connectivity. On various land cover types, we measured locomotion, as crossing speed, in different post‐metamorphic age classes, and dehydration, sensitivity of locomotion to dehydration and substrate preference in juveniles. We also tested the effect of the position in the invaded range (core vs. periphery) on individual performances.

In juveniles, general trends towards higher resistance costs on grass and lower resistance costs on bare soil and asphalt were observed, although not all experiments provided the same cost configurations. Resistance to locomotion varied between age classes, with adults and sub‐adults facing lower costs than juveniles, particularly when crossing structurally complex land cover types such as grass and leaf litter. The position in the range had a minor effect on landscape resistance, and only in the dehydration experiment, where water loss in juveniles was lower at the range periphery.

Depicting functional connectivity requires (a) assessing multiple dimensions of behavioural and physiological challenges faced by animals during movement; (b) considering factors, such as age and dispersal syndrome, that may affect movement at both individual and population levels. Ignoring this complexity might generate unreliable connectivity models and provide unsupported management recommendations for conservation.

Abstract

Dolphin morbillivirus (DMV) is a virulent pathogen that causes high mortality outbreaks in delphinids globally and is spread via contact among individuals. Broadly ranging nearshore and open‐ocean delphinids are likely reservoir populations that transmit DMV to estuarine populations.

We assessed the seroprevalence of DMV antibodies and determined the habitat use of common bottlenose dolphins, Tursiops truncatus truncatus, from two estuarine sites, Barataria Bay and Mississippi Sound, in the northern Gulf of Mexico. We predicted that risk to DMV exposure in estuarine dolphins is driven by spatial overlap in habitat use with reservoir populations.

Serum was collected from live‐captured dolphins and tested for DMV antibodies. Habitat use of sampled individuals was determined by analysing satellite‐tracked movements and stable isotope values.

DMV seroprevalences were high among dolphins at Barataria Bay (37%) and Mississippi Sound (44%), but varied differently within sites. Ranging patterns of Barataria Bay dolphins were categorized into two groups: Interior and Island‐associated. DMV seroprevalences were absent in Interior dolphins (0%) but high in Island‐associated dolphins (45%). Ranging patterns of Mississippi Sound dolphins were categorized into three groups: Interior, Island‐east and Island‐west. DMV seroprevalences were detected across Mississippi Sound (Interior: 60%; Island‐east: 20%; and Island‐west: 43%). At both sites, dolphins in habitats with greater marine influence had enriched δ13C values, and Barataria Bay dolphins with positive DMV titres had carbon isotope values indicative of marine habitats. Positive titres for DMV antibodies were more common in the lower versus upper parts of Barataria Bay but evenly distributed across Mississippi Sound.

A dolphin's risk of exposure to DMV is influenced by how individual ranging patterns interact with environmental geography. Barataria Bay's partially enclosed geography likely limits the nearshore or open‐ocean delphinids that carry DMV from interacting with dolphins that use interior, estuarine habitats, decreasing their exposure to DMV. Mississippi Sound's relatively open geography allows for greater spatial overlap and mixing among estuarine, nearshore and/or open‐ocean cetaceans. The spread of DMV, and likely other diseases, is affected by the combination of individual movements, habitat use and the environment.
