Using the extended parallel process model (EPPM) to explore US consumers' dining behaviors during COVID-19
Authors: Liu-Lastres Bingjie , Wen Han
Published: May 2022

Purpose

The purpose of this study was to examine consumers' dining behaviors and explore their decision-making process when dining out during the COVID-19 pandemic.

Design/methodology/approach

Based on the extended parallel process model (EPPM) and the related literature, a conceptual model was developed and tested. This study conducted an online survey with 351 responses. In addition, a series of statistical analyses, including descriptive analyses and path analyses, were conducted to analyze the associations among key constructs in the proposed model.

Findings

The findings of this study confirmed the pragmatic utility of applying EPPM in a hospitality management context. The findings of this study also outline the different nature between the participants' enactment of self-protective measures and dining out activities. Lastly, while consumers are hesitant about dining out, the results showed that consumers' dining behaviors are directly related to their personality trait of sensation-seeking.

Research limitations/implications

This study was delimited to a cross-sectional design and self-reported data. Such information may provide insights into individuals' decision-making and behaviors related to dining in a COVID-19 context. In addition, this study only includes US samples, while future studies can extend this study by including samples from different countries and cultural backgrounds.

Originality/value

This study adopts an interdisciplinary approach, which derives from tourism and hospitality management and public health. As a result, the findings of this study not only identify the major influencers affecting consumers' dining behavior but also help contextualize a public health model and contribute to the tourism and hospitality management literature.
Shape optimization of synchronous reluctance motor using sensitivity information for multiple objective functions
Authors: Shigematsu Hiroki , Wakao Shinji , Makino Hiroaki , Takeuchi Katsutoku , Matsushita Makoto
Published: May 2022

Purpose

This paper aims to further improve the efficiency of multi-objective optimization design of synchronous reluctance motors (SynRMs) using the level set (LS) method, which has the advantage of obtaining a practical shape. The solutions obtained by gradient methods tend to be local ones due to the multi-modality of the objective function, especially when multiple objective functions. A huge number of trial calculations are required to obtain a high-quality and broadly distributed Pareto front. Therefore, it is indispensable to effectively get out of the local solutions in the optimization process with the LS method.

Design/methodology/approach

The authors propose a novel method appropriately switching multiple objective functions with high independence of sensitivity information. The authors adopt highly independent mathematical expressions for the objective functions of the average torque and torque ripple. In addition, the authors repeatedly perform the optimization while appropriately selecting the sensitivity information of one objective function from multiple ones, which enables the authors to effectively break out of local solutions in the optimization process.

Findings

The proposed method was applied to the shape optimization of SynRM flux barriers and successfully searched a more extensive and advanced Pareto front in comparison with the conventional method.

Originality/value

The proposed method adopts search spaces with mathematical high independence for average torque and torque ripple. In the optimization process, when the solution search is judged to get stuck by several criteria, the search space is alternately switched to effectively get out of local solutions.
The threshold effect of commitment-oriented HRM practices on employee job performance: the role of employee age
Authors: Yu Mingchuan , Jiao Qianying , Wang Greg G. , Liu Yuan
Published: May 2022

Purpose

To reconcile the mixed findings on commitment-oriented human resource management (HRM) on employee job performance, this study tests whether commitment-oriented HRM has a threshold effect on employee job performance and when this threshold effect matters. The authors further tested the role of employees' age in the relationships.

Design/methodology/approach

The authors conducted a survey and collected data from 601 employees in 32 firms in China, and used a multilevel approach to test the hypothesis.

Findings

The results showed that the association between commitment-oriented HRM and employee job performance was J-shaped, meaning that commitment-oriented HRM was positively related to job performance when the degree of commitment-oriented HRM exceeded a threshold. Moreover, the authors found that employee age moderated this J-shape relationship. Specifically, the curvilinear relationship between development commitment-oriented HRM and job performance was stronger in younger employees. Contrary to our prediction, the results showed that younger employees reacted more strongly to improve job performance than older employees when maintenance commitment-oriented HRM exceeded a moderate degree.

Originality/value

The findings on the J-shape effect and moderating role of employee age on the J-shape provided critical insights into understanding the mixed results of the effect of HRM. Additionally, this study provided new insight in the linkage between HRM practices and employee outcomes.
The influence of general causality orientations on self-esteem and perceived stress among undergraduate students in women-only colleges
Authors: Uruthirapathy Aareni , Dyke Lorraine
Published: May 2022

Purpose

General causality orientation is a mini-theory within the self-determination theory (STD). The purpose of this study was to examine the influence of general causality orientations (autonomous, controlled, and impersonal) on perceived stress and self-esteem among students in a women-only college.

Design/methodology/approach

Data were collected through a questionnaire administered to students (n = 132) of a small women-only university in Roanoke, Virginia, USA. The survey included questions on the three general causality orientations, perceived stress, and self-esteem; the survey also included questions on student satisfaction, financial resources, and academic performance, used as control variables in the study.

Findings

Autonomous orientation was not significantly related to self-esteem or perceived stress. Controlled orientation negatively influences self-depreciation. Finally, impersonal orientation positively influenced self-depreciation and negatively affected self-confidence.

Practical implications

Faculty and administrators in women-only universities should be encouraged to implement programs that strengthen the sense of optimism among female students. Student support services that emphasize enhancing autonomous orientation could be even more helpful by offering interventions that help students overcome their impersonal orientation.

Originality/value

While previous studies have concentrated on autonomous orientation, this study provides recommendations for overcoming impersonal orientation among female undergraduate students in women-only colleges to enhance self-esteem and reduce stress.
Crude oil, crypto-assets and dependence: the impact of the COVID-19 pandemic
Authors: Mzoughi Hela , Ghabri Yosra , Guesmi Khaled
Published: May 2022

Purpose

This paper aims to empirically investigate the extent to which interdependence in markets may be driven by COVID-19 effects.

Design/methodology/approach

The current global COVID-19 pandemic is adversely affecting the oil market (West Texas Intermediate) and crypto-assets markets.

Findings

The authors find that the dependence structure changes significantly after the global pandemic, providing valuable information on how the COVID-19 crisis affects interdependencies. The results also prove that the performance of digital gold seems to be better compared to stablecoin.

Originality/value

The authors fit copulas to pairs of before and after returns, analyze the observed changes in the dependence structure and discuss asymmetries on propagation of crisis. The authors also use the findings to construct portfolios possessing desirable expected behavior.
The effect of small business financing decision on business performance in Ghana: the moderated mediation role of corporate governance system
Authors: Tetteh Lexis Alexander , Kwarteng Amoako , Gyamera Emmanuel , Lamptey Lazarus , Sunu Prince , Muda Paul
Published: May 2022

Purpose

The paper aims to investigate the role of corporate governance in the relationship between small businesses financing choice decisions on the business performance.

Design/methodology/approach

The paper was situated within the financial growth cycle theory and stewardship theory and survey approach was adopted for data collection. The statistical analysis was conducted by using partial least square structural equation modelling.

Findings

The results indicate that the interaction of corporate governance and financing choice decisions strengthens the performance relationship. Further, corporate governance mediates the positive relationship between financing choice decisions and performance. Thus, suggesting that corporate governance can carry the effect of the financing choice decisions to business performance.

Practical implications

The findings of our research reveal that, small businesses who follow solid corporate governance procedures should expect higher business performance. This is because financing decisions alone will not assure positive business performance unless they are tied to a broader perspective of effective corporate governance practices.

Originality/value

To the best of the authors’ knowledge, this is the first study that contributes to the small business financing choice and performance literature by combining the strengths of financial growth cycle theory and stewardship theory to explain the financing choice decisions and, in particular, the role of corporate governance in the relationship. Further, the study is unique in its nature because it presents a successful model for small businesses in emerging economies to concentrate more on the role of corporate governance in enhancing business performance.
Flexibility out of standardization
Authors: Cabri Giacomo , Fioretti Guido
Published: May 2022

Purpose

This article aims to provide a theoretical unifying framework for flexible organizational forms, such as so-called adhocracies and network organizations.

Design/methodology/approach

In this article, organization practices that are typical of the software industry are analyzed and re-interpreted by means of foundational concepts of organization science. It is shown that one and the same logic is at work in all flexible organizations.

Findings

Coordination modes can be fruitfully employed to characterize flexible organizations. In particular, standardization is key in order to obtain flexibility, provided that a novel sort of coordination by standardization is added to those that have been conceptualized hitherto.

Research limitations/implications

This article highlights one necessary condition for organizations to be flexible. Further aspects, only cursorily mentioned in this paper, need to be addressed in order to obtain a complete picture.

Practical implications

A theory of organizational flexibility constitutes a guide for organizational design. This article suggests the non-obvious prescription that the boundary conditions of individual behavior must be standardized in order to achieve operational flexibility.

Social implications

This theoretical framework can be profitably employed in management classes.

Originality/value

Currently, flexible organizations are only understood in terms of lists of instances. This article shows that apparently heterogeneous case-studies share common features in fact.
Reading ‘rithmatic: examining the impact of a literacy intervention on mathematics placement assessment
Authors: Cardenas Elliott Diane , Sand Dianna , Jones Elizabeth
Published: May 2022

Purpose

College placement assessments in the USA have underperformed in predicting college readiness. This has prompted a wave of reforms to placement practices and policies. Recently, student preparation for placement assessments has come to the forefront as a means for enabling better evaluation of college readiness. In this study, the authors explored the effects of an intervention aimed at preparing students for precollege placement assessments. The intervention focused on the provision of mathematics discipline-specific literacy skills because demonstrating mathematical mastery depends on students’ ability to read, understand and translate text into mathematical computations.

Design/methodology/approach

In this study, the authors used a randomized control trial design. The design enabled the authors to draw causal inferences while examining the effects of a placement assessment preparation intervention on mathematics placement and course outcomes. The authors also examined the intervention’s effect across incoming first-year college students with varying levels of readiness.

Findings

Findings demonstrated a positive and significant effect on assessment scores and placement for intervention participants with a stronger effect for those with higher levels of readiness. Intervention participants exhibited comparable academic success outcomes as those who did not receive the intervention.

Originality/value

Little assessment research has explored the intersection of mathematics and literacy skills in relation to college readiness assessment. In addition, findings support the utility of preparation for college placement assessments.

Authors: Arzubiaga Unai , Schiavone Francesco , Ali Mohamad Talal , Chen Junsong
Published: May 2022

Purpose

The purpose of this study is to explore the marketing success factors of an international private healthcare company operating in Lebanon and examine how these factors evolve depending on different business phases.

Design/methodology/approach

An extreme single-case study of a Lebanese healthcare center was conducted. The data sources consisted of semi-structured interviews and archival data including industry reports, newspaper articles and internal documents.

Findings

This study offers interesting, non-studied insights into marketing success factors in the private healthcare sector. In particular, it shows how to evolve from more traditional business models to disruptive yet very attractive personalized services with high-quality standards.

Research limitations/implications

While the theoretical position developed fits the unique characteristics of the studied industry and country settings, it is necessary to be cautious in generalizing the study to other geographical settings and industries.

Practical implications

This research provides managers and decision-makers with insights into how to identify, organize and develop success factors in the marketing discipline during different business phases of private healthcare organizations.

Originality/value

This study contributes to the scarce literature on the marketing of private healthcare organizations by exploring success factors in a non-studied geographical and cultural context.
Humanistic communication professionals: dialogue and listening skills as core competencies of humanistic communication professionals in the Netherlands
Authors: Elshof Marjon , Hendrawan Bram
Published: May 2022

Purpose

Many organisations wrestle with how to develop value-oriented businesses and societies. A humanistic communication approach that promotes understanding and dialogue amongst stakeholders can contribute to a solution. Communication professionals play a pivotal role in achieving a humanistic communication process. This paper aims to determine the significance of humanistic communication professionals and their characteristics.

Design/methodology/approach

A literature review was conducted to identify the characteristics of humanistic communication professionals. Thereafter, the extent to which such characteristics have been implemented in competency models in the Netherlands was investigated. This country’s strong tradition of developing competencies for communication professionals has resulted in competency models that serve as standards for professional development.

Findings

The literature review shows that a humanistic approach to communication is characterised by dialogic engagement and social listening to build and maintain trust, foster transparency and create engagement with stakeholders. Communication professionals can act as “cultural interpreters”, “organisational listeners” and “stewards of meaning”. The human element plays a key factor in the competency standards for communication professionals in the Netherlands, although the extent to which they are embedded varies. The analysis shows a shift from passing on a message towards dialogue and engagement.

Originality/value

Most studies of communication professionals’ competencies have been based on roles or tasks they perform. Little scholarly attention has been paid to competencies that add to developing value-oriented businesses and societies. This paper focuses specifically on how communication professionals can contribute to creating humanistic organisations.
Relationship of brand credibility and brand loyalty: the mediating effects of attitude toward brand
Authors: Haq M. Ikram Ul , Khaliq Alvi Abdul , Somroo Muhammad Akram , Akhtar Nadeem , Ahmed Ashfaque
Published: May 2022

Purpose

Current research addresses the issue of brand loyalty while identifying its potential predictors. The research also examines the direct impact of brand credibility on brand loyalty and attitude toward brand and the direct impact of attitude toward brand and on brand loyalty respectively. Moreover, this research examines the mediating effect of attitude toward brand for the relationship of brand credibility and brand loyalty.

Design/methodology/approach

This is a cross-sectional research. Data is collected with the help of structured questionnaire. Simple random sampling technique is used for gathering the data from 220 Samsung users from Lahore, Pakistan.

Findings

Results indicate that brand credibility has a positive influence on attitude toward brand and brand loyalty respectively. Attitude toward brand partially intervenes the relation of brand credibility and brand loyalty.

Research limitations/implications

There are some limitations of the current research. It includes only the customers of Samsung mobile. Data is collected from the customers of Lahore, Pakistan, only. This research can also be conducted among the customers of OPPO, Vivo and Apple and compare the results of current research with the results of OPPO, Vivo and Apple, which will provide the useful insights. This kind of research will also be conducted among the customers of other kinds of products like FMCGs, luxury items and even on the organizations of industrial products for generalizability. In future, customers of other cities of Pakistan like Karachi, Multan and Faisalabad may also be included for generalization.

Practical implications

This research provides a practical framework for the marketing department of Samsung mobiles and explains how brand credibility shape the brand loyalty through the path of attitude toward Samsung mobiles. So, Samsung mobiles can maintain current policies regarding brand credibility and attitude toward brand for attaining the better level of brand loyalty. Longitudinal research studies on these variables will also be helpful for the marketing department of Samsung for checking the level of propose relationships periodically and comparing it with previous results which will provide the true picture about propose relationships. If the value of propose relationships increases or remains at same level, then Samsung can maintain the current policies about these variables and if the value of these variables decreases, the Samsung will improve the current policies about these variables.

Originality/value

This research contributed in theory of reasoned action by proposing the brand credibility, attitude toward brand and brand loyalty in single model. Before this, these relations were explained separately. This research adds to the body of literature by checking the mediating effect of attitude toward brand for the relationship of brand credibility and brand loyalty.
Analyzing the green financing and energy efficiency relationship in ASEAN
Authors: Quang Phung Thanh , Thao Doan Phuong
Published: May 2022

Purpose

The need to improve energy efficiency as an essential factor for achieving the Sustainable Development Goals (SDGs) through green financing is one of the most important issues worldwide. It is even more important for ASEAN (Association of Southeast Asian Nations) countries because of their potential for economic growth and the challenge of their environmental problems. This paper therefore addresses the question of whether and how green finance (with the proxy of issued green bonds [GBs]) promotes energy efficiency (with the proxy of energy intensity) in the ASEAN member countries.

Design/methodology/approach

The paper runs a two-stage generalized method of moments (GMM) system model for the quarterly data over the period 2017–2020. It also uses a linear interaction model to explore how the pandemic may affect the relationship between green finance and energy efficiency in this region.

Findings

The main results only demonstrate the short-term negative impact of GBs on energy intensity. Furthermore, per capita income, economic integration and renewable energy supply can be used as potential variables to reduce energy intensity, while modernization in ASEAN increases energy intensity. Establishment of digital green finance, long-term planning of a green finance market, trade liberalization and policies to mitigate the negative impacts of COVID-19 are recommended as golden policy implications.

Research limitations/implications

The present study has several limitations. First, it accounts for explanatory variables by following a number of previous studies. This may lead to omissions or errors. Second, the empirical estimates were conducted for 160 observations due to the repositioning of GBs in ASEAN, which is not bad but not good for an empirical study.

Originality/value

To the best of authors' knowledge, there has not been any in-depth study focusing on the relationship between energy efficiency and green financing for the case of ASEAN economies.
Longitudinal upgrades and asymmetric effects of satisfaction and perceived-value
Authors: Miller Chadwick J. , Sajtos Laszlo , Lemon Katherine N. , Salas Jim , Troncoza Martha , Ostrom Lonnie
Published: May 2022

Purpose

The purpose of this paper is to investigate how customers’ upgrading/downgrading (t−1) behavior may be predictive of future spending. Further, this paper also investigates how customers’ post-consumption evaluations of upgrades and downgrades [satisfaction(t−1) and perceived value(t−1)] may moderate the relationship between upgrades/downgrades and future spending.

Design/methodology/approach

The predictions are tested using a large longitudinal data set of river cruise purchases (N = 48,103) and largely replicated using a data set of zoo membership purchases (N = 2,469).

Findings

Satisfaction(t−1) mitigates the positive relationship between prior upgrades(t−1) and future spending(t). In contrast, perceived value(t−1) magnifies the positive relationship between prior upgrades(t−1) and future spending(t). However, no positively moderating effects are observed to alleviate the negative relationship between prior downgrades(t−1) and future spending(t).

Practical implications

This research suggests that managers should work hard early in customer–firm relationships because of an asymmetric difficultly in altering the trajectory of an established relationship. Specifically, relationships that are trending downward (as consecutive downgrades would suggest) are difficult to repair – a mechanism to alter this trajectory is not observed. In contrast, relationships that are trending upward (as consecutive upgrades would suggest) can be improved with high perceived value evaluations but also degraded with high satisfaction evaluations.

Originality/value

This research should recast marketers’ understanding of the value of customers’ upgrade and downgrade decisions. Instead of using customers’ upgrade or downgrade decisions as the dependent variable, or final outcome in buyer behavior, this study shows how the accumulation of prior upgrades and prior downgrades, over time, acts as a bellwether of the customer–firm relationship. Further, to the best of the authors’ knowledge, this study is the first to connect these upgrade/downgrade decisions to customers’ evaluations of those purchases to understand how individual purchases can impact the overall customer–firm relationship.
Technology acceptance by university lecturers: a reflection on the future of online and hybrid teaching
Authors: Weilage Christopher , Stumpfegger Eva
Published: May 2022

Purpose

Most research using extended unified theory of acceptance and use of technology (UTAUT2) and other technology acceptance models (TAM) are quantitative studies. This leaves room for interpretation when they are applied to university lecturers’ acceptance of online teaching because the models were originally created for the consumer perspective. This study aims to bridge this gap by integrating existing (quantitative) research with (qualitative) reasoning.

Design/methodology/approach

This study reflects online and hybrid teaching acceptance by reviewing exemplary existing research using UTAUT2 as the conceptual framework.

Findings

UTAUT2 TAMs use a broad range of criteria that do not immediately agree with university lecturers’ acceptance of online teaching. This study finds that existing research results are inconclusive and attempts to link criteria when suitable. Performance expectancy should not only encompass individual attitudes and skills but also the nature of the subject taught. Social influence is driven by recognition and student evaluations. Hedonic motivation best fits the elsewhere well-researched concept of intrinsic motivation. This study suggests that universities choose their online teaching technology wisely, promote its ease of use and offer training as well as continuous support to lecturers, especially when addressing future uncertainties.

Originality/value

This study explains the implications of using TAMs for research of higher education online teaching. Potential reasons and arguments for the inconclusiveness of the studies reviewed are discussed, and measures for university policy and communication improvement are suggested.
Social media in learning on nature: case Finnish amateur mycologists
Authors: Santaoja Minna
Published: May 2022

Purpose

Eco-social crises such as the loss of biodiversity call for transformative learning. This study analyzes the prospects of social media in learning about nature.

Design/methodology/approach

The study is placed in the intersection of science and technology studies, futures studies, environmental social sciences, and environmental humanities. The study draws on a qualitative case study of a mycologists' Facebook group. The empirical material was collected through digital ethnography.

Findings

Social media provides opportunities for learning about nature for many people. However, specialized naturalist social media groups are increasingly geared towards citizen science. The development may fragment the online naturalist cultures and narrow the scope for learning.

Research limitations/implications

Insights from a single case study cannot be broadly generalized. However, the case highlights significant features to consider in promoting collective learning in social media in the future.

Originality/value

Much of the previous research has focused on social media uses in the formal education of youth. This study addresses social media in informal and collective learning, specifically about nature.
The frequency and clustering of autism-related behaviors during encounters between the police and the autism community
Authors: Wallace Danielle , Herbert Jessica , McGhee Hassrick Elizabeth , Kabourek Sarah E.
Published: May 2022

Purpose

This paper intends to examine the behaviors autistic individuals display during police encounters, determine if there are differences in those behaviors by age and gender, then examine if any behaviors cluster or frequently co-occur.

Design/methodology/approach

Using data from the Survey of Parents and Caregivers of Individuals with autism spectrum disorder and focusing on a subsample of respondents who report that their autistic loved one has had prior police contact, the authors examine the frequency and clustering of behaviors displayed by autistic individuals during police encounters. The authors use chi-square tests of independence to examine age and gender differences and latent class analysis to assess behavioral clustering.

Findings

The findings show that many behaviors that autistic individuals display during police encounters are associated with social communication and interaction difficulties, such as failure to maintain eye contact and difficulty answering questions. Many of these overlap with police training on deception, compliance and passive resistance. Moreover, the authors find that there are age differences in two behaviors, fidgeting and not responding to one's name. Lastly, the authors find that many of these behaviors cluster in unexpected ways, adding a layer of complexity to encounters between the police and autistic individuals.

Originality/value

Training police officers, autistic individuals and their loved ones on interactions with the police is critical for positive outcomes. Without details on what occurs inside a police encounter, constructing those trainings is difficult. While this study provides only a small glimpse into police encounters with the autistic community, it is a first step toward understanding these multifaceted interactions better.
Research on rail wear of small radius curve in EMU depot
Authors: Li Hao , Sun Jialin , Zhao Guotang
Published: May 2022

Purpose

With the help of multi-body dynamics software UM, the paper uses Kik–Piotrowski model to simulate wheel-rail contact and Archard wear model for rail wear.

Design/methodology/approach

The CRH5 vehicle-track coupling dynamics model is constructed for the wear study of rails of small radius curves, namely 200 and 350 m in Guangzhou East EMU Depot and those 250 and 300 m radius in Taiyuan South EMU Depot.

Findings

Results show that the rail wear at the straight-circle point, the curve center point and the circle-straight point follows the order of center point > the circle-straight point > the straight-circle point. The wear on rail of small radius curves intensifies with the rise of running speed, and the wearing trend tends to fasten as the curve radius declines. The maximum rail wear of the inner rail can reach 2.29 mm, while that of the outer rail, 10.11 mm.

Originality/value

With the increase of the train passing number, the wear range tends to expand. The rail wear decreases with the increase of the curve radius. The dynamic response of vehicle increases with the increase of rail wear, among which the derailment coefficient is affected the most. When the number of passing vehicles reaches 1 million, the derailment coefficient exceeds the limit value, which poses a risk of derailment.
Experimental study of the wheel/rail impact caused by wheel flat within 400 km/h using full-scale roller rig
Authors: Chang Chongyi , Cai Yuanwu , Chen Bo , Li Qiuze , Lin Pengfei
Published: May 2022

Purpose

In service, the periodic clashes of wheel flat against the rail result in large wheel/rail impact force and high-frequency vibration, leading to severe damage on the wheelset, rail and track structure. This study aims to analyze characteristics and dynamic impact law of wheel and rail caused by wheel flat of high-speed trains.

Design/methodology/approach

A full-scale high-speed wheel/rail interface test rig was used for the test of the dynamic impact of wheel/rail caused by wheel flat of high-speed train. With wheel flats of different lengths, widths and depths manually set around the rolling circle of the wheel tread, and wheel/rail dynamic impact tests to the flats in the speed range of 0–400 km/h on the rig were conducted.

Findings

As the speed goes up, the flat induced the maximum of the wheel/rail dynamic impact force increases rapidly before it reaches its limit at the speed of around 35 km/h. It then goes down gradually as the speed continues to grow. The impact of flat wheel on rail leads to 100–500 Hz middle-frequency vibration, and around 2,000 Hz and 6,000 Hz high-frequency vibration. In case of any wheel flat found during operation, the train speed shall be controlled according to the status of the flat and avoid the running speed of 20 km/h–80 km/h as much as possible.

Originality/value

The research can provide a new method to obtain the dynamic impact of wheel/rail caused by wheel flat by a full-scale high-speed wheel/rail interface test rig. The relations among the flat size, the running speed and the dynamic impact are hopefully of reference to the building of speed limits for HSR wheel flat of different degrees.
Service research: past, present and future research agenda
Authors: Arici Hasan Evrim , Köseoglu Mehmet Ali , Altinay Levent
Published: May 2022

Purpose

This study aims to explore past and present service research and to provide a future research agenda for service researchers by presenting a big picture of the intellectual connections and emerging topics in the discipline.

Design/methodology/approach

This study is an empirical analysis of citations and cocitations on a sample of 5,837 articles published in leading service journals (from 1981 to December 2020). Network analysis was adopted to analyze the data. This study is exclusive in conducting the inquiry at the individual publication level, rather than using the normal aggregated author co-citation analysis approach.

Findings

The findings reveal that the main themes of service research centered on customer satisfaction, service quality, service-dominant logic, methodological foundations, market orientation and service encounter. Also clarified is the periphery domain that may become more important in the future (i.e. technology). The findings also present anchor points for conceptual framing and conceptual development – five main themes that are momentous to navigate theory discovery and justification in the knowledge domain.

Research limitations/implications

It calls for a more academic effort to evaluate the service research by considering different epistemological paradigms, such as positivism, monologic and hermeneutic, to better understand the process and progress of the discipline.

Practical implications

Through exploring the transformation of service research into a customer-centric model and technology-based service logic, this study offers possible implications for practitioners and further research areas for service researchers.

Originality/value

To the best of the authors’ knowledge, this study is the first to use a citation, cocitation and network analysis to examine service research published in leading service journals. This study provides a significant contribution to the theory by combining main conceptual areas and interests in the given discipline.
High nitrogen‐fixing rates associated with ground‐covering mosses in a tropical mountain cloud forest will decrease drastically in a future climate
Authors: Permin Aya , Horwath Aline B. , Metcalfe Daniel B. , Priemé Anders , Rousk Kathrin
Published: May 2022

Tropical mountain cloud forests (TMCF) harbour a high bryophyte (mosses and liverworts) biomass and diversity. Furthermore, the high air humidity makes these forests well suited for bryophyte‐associated nitrogen (N2) fixation by cyanobacteria, providing a potentially important source of N input to the ecosystem. However, few studies have assessed bryophyte‐associated N input in these ecosystems, and these have focused on epiphytic bryophytes, whereas abundant ground‐covering bryophytes have not been included.

In this study, we quantified N2 fixation rates associated with bryophytes, focusing on ground‐covering mosses in a neotropical mountain cloud forest. Furthermore, we identified the effects of climate change (higher temperature 10 vs. 20° and lower bryophyte moisture level 50% vs. 100%) on N2 fixation across bryophyte species and groups (mosses and liverworts).

Nitrogen fixation rates associated with ground‐covering moss species were up to 2 kg N ha−1 year−1, which is comparable to other N inputs (e.g. N deposition) in tropical cloud forests. Furthermore, changes in temperature showed little effect on N2 fixation, but low moisture levels significantly suppressed N2 fixation activity. We found low N2 fixation activity associated with the investigated liverworts.

Our results demonstrate the importance of ground‐covering, moss‐associated N2 fixation as a N source in tropical cloud forests and suggest that predicted future declines in precipitation in these systems will reduce N inputs from bryophyte‐associated cyanobacteria.

High‐resolution and robust microseismic grouped imaging and grouping strategy analysis
Authors: Huang Guangtan , Chen Xiaohong , Saad Omar M. , Chen Yunfeng , Savvaidis Alexandros , Fomel Sergey , Chen Yangkang
Published: May 2022

As an advanced real‐time monitoring technique, microseismic source‐location imaging provides valuable information during hydraulic fracturing, for example, the development of fracture networks and the effective reservoir reconstruction volume. However, microseismic data always suffer from weak induced energy and susceptibility to noise interference. In the case of a low signal‐to‐noise ratio, it is extremely challenging to perform robust microseismic imaging. Here, we first introduce several state‐of‐the‐art imaging conditions and two hybrid imaging conditions, which are followed by a detailed analysis of the impact of different grouping strategies. Then, we briefly analyse the sensitivity of different imaging conditions to noise using a one‐dimensional signal. Next, several benchmark models, including two‐dimensional Marmousi‐II and three‐dimensional SEG Advanced Modeling, are used as numerical examples for testing the passive‐source imaging algorithms. Finally, three‐dimensional real microseismic data are used to further investigate the impact of the grouping strategy on the imaging. The numerical examples and field data demonstrate the effectiveness of the proposed grouping strategy for the grouped imaging conditions.
Are behaviour and stress‐related phenotypes in urban birds adaptive?
Authors: Caizergues Aude E. , Grégoire Arnaud , Choquet Rémi , Perret Samuel , Charmantier Anne
Published: May 2022

Urbanisation is a world‐wide phenomenon converting natural habitats into new artificial ones. Environmental conditions associated with urbanisation represent great challenges for wildlife. Behaviour and stress tolerance are considered of major importance in the adaptation to novel urban habitats and numerous studies already reported behavioural and stress response phenotypes associated with urbanisation, often suggesting they represented adaptations, while rarely demonstrating it.

The main goal of this study was to test the adaptive nature of urban shifts in behavioural and stress‐related traits, and by adaptive we mean phenotypic change favouring traits in the same direction as selection.

Using 7 years of monitoring of urban and forest great tits, we first tested for differences in exploratory behaviour, aggressiveness and breath rate, between both habitats. Second, we performed habitat‐specific analyses of selection on the three former traits using (a) reproductive success and (b) survival estimated via capture–mark–recapture models, as fitness estimates, to determine whether shifts in these behavioural and stress‐related traits were aligned with patterns of ongoing selection.

We found that urban birds displayed higher exploratory behaviour and aggressiveness, and higher breath rate, compared to forest birds. Selection analyses overall revealed that these shifts were not adaptive and could even be maladaptive. In particular, higher handling aggression and higher breath rate in urban birds was associated with lower fitness. Higher exploration scores were correlated with lower survival in both habitats, but higher reproductive success only in forest males. Overall, differences in patterns of selection between habitats were not consistent with the phenotypic divergence observed.

Taken together, these results highlight that phenotypic shifts observed in cities do not necessarily result from new selection pressures and could be maladaptive. We hypothesise that divergences in behavioural traits for urban birds could result from the filtering of individuals settling in cities. We thus encourage urban evolutionary scientists to further explore the adaptive potential of behavioural traits measured in urban habitats (a) by replicating this type of study in multiple cities and species, (b) by implementing studies focusing on immigrant phenotypes and (c) by measuring selection at multiple life stages.
Professional reasoning of occupational therapy driver rehabilitation interventions

Introduction

Driver‐trained occupational therapists are advanced practitioners who work with people to help maintain their independence and autonomy through driving. There is a lack of investigation of professional reasoning processes for why interventions are recommended by driver‐trained occupational therapists. This research project sought to explore the reasoning of driver‐trained occupational therapists when they plan, implement, and reflect on driver rehabilitation interventions.

Methods

In‐depth semistructured interviews (n = 7) and one focus group (n = 5) were conducted with 12 experienced driver‐trained occupational therapists, comprising a wide range of experience, client populations, and licensing jurisdictions. Data were analysed using a modified template analysis approach.

Results

Seven higher order modes that reflect professional reasoning theory and hierarchical models were evident in the work of the driver‐trained occupational therapists, with no new modes of reasoning emerging. Ethical reasoning regarding the balance of safety versus client independence was an overarching shared framework, with therapists mostly using interactive and conditional reasoning in practice. Twenty‐three second‐level themes were identified that exemplify how the reasoning modes operate in practice. Therapists described assessment activity even when solely asked about intervention, indicating the importance of assessment to intervention design. The full hierarchy of reasoning was evident during the rehabilitation phase.

Conclusion

These findings elucidate the application of professional reasoning in advanced occupational therapy practices and could support driver‐trained occupational therapists in making driving rehabilitation recommendations if used in reflective practices.
Possible involvement of apoptosis in the antipsychotics side effects: A mini‐review

Antipsychotics are used in the treatment of schizophrenia and other psychiatric disorders. Generally, they are divided into typical and atypical ones, according to the fact that atypical antipsychotics induce fewer side effects and are more effective in terms of social and cognitive improvements. Their pharmacological effects are mediated via broad range of receptors that consequently influence different cellular signalling pathways. Antipsychotics produce undesirable side effects that range from relatively minor to life threatening. In vitro and in vivo studies have pointed to neurotoxic effect exerted by some antipsychotics and have shown that apoptosis might play role in some side effects induced by antipsychotics, including tardive dyskinesia, weight gain, agranulocytosis, osteoporosis, myocarditis, etc. Although cumulative data have suggested safety of atypical antipsychotics use during pregnancy, some of them have been shown to induce apoptotic neurodegenerative and structural changes in fetal brains with long‐lasting impact on cognitive impairment of offspring. Typical antipsychotics seem to be more cytotoxic than atypical ones. Recently, epidemiological studies have shown lower incidence of cancer in schizophrenic patients that suggest the ability of antipsychotics to suppress risk of cancer development. Some antipsychotics have been reported to inhibit cancer cell proliferation and induce their apoptosis. Therefore, antipsychotics apoptotic effect may be used as a tool in the treatment of some types of cancer, especially in combinatorial therapies. In this mini‐review, we focused on pro‐ and antiapoptotic or ‘Dr. Jekyll and Mr. Hyde’ effects of antipsychotics, which can be involved in their side effects, as well as their promising therapeutic indications.
Bacterial tRNA landscape revisited

The updated Wobble Hypothesis reasonably explains why some 40 tRNA species are sufficient to decode the 61 amino acid codons of the Universal Genetic Code. However, we still have no clue why eubacteria lack tRNA isoacceptors with ANN anticodons, whereas eukaryotes universally lack eight GNN anticodons, only one of which is also absent in bacteria. Direct tRNA sequencing could resolve the patterns of nucleoside modification that had been driving the divergent evolution in prokaryotes and eukaryotes, but this task will require the development of AI‐supported base‐callers that can recognize modified nucleosides without any subsequent analytical verification. Our knowledge of the bacterial tRNA landscape is moreover broadened by the recent discovery of antisense tRNAs and tRNA‐derived fragments that should be examined in their roles for gene expression, translation, bacterial physiology or metabolism.
Organizational career management in the new career era: scale development and validation

Despite the widely recognized change of career management in the new career era, little is known about whether current organizational career management practices differ from previous ones. Using an open‐ended survey and literature review, this study develops a scale of organizational career management that shows some features of the new career era (e.g. boundaryless career, protean career, kaleidoscope career, etc.) in China. We conducted two independent studies (N = 320;N = 216) to examine the reliability and validity of the scale. The final organizational career management scale includes four dimensions: boundaryless work, work‐life balance policies, training and development and diversification. Further, we tested both the possible bright side and dark side of organizational career management in contemporary organizations using 179 employees over a two‐month interval. We found that both a bright side (i.e. higher organizational commitment and less turnover intention) and a dark side (i.e. higher career competency and more likely to leave organizations) exist. This article discusses the contributions, practical complications, limitations and future research directions.
