Published: June 2023

Atomic model refinement at low resolution is often a challenging task. This is mostly because the experimental data are not sufficiently detailed to be described by atomic models. To make refinement practical and ensure that a refined atomic model is geometrically meaningful, additional information needs to be used such as restraints on Ramachandran plot distributions or residue side-chain rotameric states. However, using Ramachandran plots or rotameric states as refinement targets diminishes the validating power of these tools. Therefore, finding additional model-validation criteria that are not used or are difficult to use as refinement goals is desirable. Hydrogen bonds are one of the important noncovalent interactions that shape and maintain protein structure. These interactions can be characterized by a specific geometry of hydrogen donor and acceptor atoms. Systematic analysis of these geometries performed for quality-filtered high-resolution models of proteins from the Protein Data Bank shows that they have a distinct and a conserved distribution. Here, it is demonstrated how this information can be used for atomic model validation.
Implementation of circular economy in construction projects: a procurement strategy approach
Authors: Ahmed Siraj , Majava Jukka , Aaltonen Kirsi 
Published: June 2023

Purpose
The purpose of this study is to investigate the benefits and challenges of implementing circular economy (CE), as well as shed light on the influence of procurement strategy in CE implementation in construction projects.

Design/methodology/approach
A qualitative research approach with abductive reasoning was adopted. The empirical data were collected from the construction industry in the United Arab Emirates (UAE).

Findings
The results reveal that clients, consultants and contractors have limited awareness, knowledge and motivation to implement CE in construction projects. The absence of incentives to design projects following CE principles, lack of involvement of contractors and suppliers, non-use of materials that use CE principles and current procurement strategies are the main challenges for the implementation of CE in the UAE.

Originality/value
Previous research offers limited knowledge on CE and its implementation in construction projects particularly from a procurement strategy perspective. The findings of the study provide new knowledge of the benefits, challenges and role of procurement strategy for implementing CE. It is suggested that collaborative and partnering-based procurement methods are needed to facilitate the effective implementation of CE.
The influence of the pillars of digital academic entrepreneurship on university students’ entrepreneurial intention
Authors: Garcez Ana , Franco Mário , Silva Ricardo 
Published: June 2023

PurposeThis study aims to analyse the influence of the pillars (hard and soft skills) of digital academic entrepreneurship on students' entrepreneurial intention.Design/methodology/approachThis was done by adopting a quantitative methodology involving empirical research with a sample of 761 university students from two countries and adopting structural equation analysis to validate the theoretical model proposed.FindingsThe results indicate a direct influence between hard and soft skills and entrepreneurial intention, and a positive, indirect influence between these and entrepreneurial intention mediated by the dimensions of the theory of planned behaviour (TPB) – entrepreneurial attitude, subjective norms and perceived behavioural control. Therefore, the pillars of digital academic entrepreneurship have a direct and indirect influence on university students' entrepreneurial intention.Practical implicationsThis study also contributes to better operationalization of entrepreneurial education in university environments, since the development of hard and soft skills can be planned better based on the model proposed here. Considering the relations between the dimensions of hard and soft skills and those of TPB, this study shows there can be an influence on students' entrepreneurial intention.Originality/valueIn this study, a new and innovative construct is inserted in the model of entrepreneurial intention: “structural pillars of digital academic entrepreneurship” through structural equation modelling, to determine the degree of influence of these pillars (hard and soft skills) constructs on HEI students' entrepreneurial intention.

Authors: Bertucci Ramos Paulo Henrique , Pedroso Marcelo Caldeira 
Published: June 2023

PurposeThis study aims to propose and assess a model with the main elements influencing Brazilian agtech scalability with the aim of supporting the scalability process of startups that find themselves in the stage of initial conception of the business model.Design/methodology/approachThe research was conducted using the design science research (DSR) method. The data for assessing the proposed model were collected through in-depth interviews. The answers were analyzed quantitatively, using descending hierarchical classification (DHC), correspondence factor analysis (CFA), and level of agreement; and qualitatively, using content analysis.FindingsConsidering the Brazilian context, the objective, environmental, structural, and evaluative dimensions presented positive characteristics for the main criteria analyzed (operational viability, generality, clarity, adaptation to the reality studied, completeness, consistency, comprehensibility, and structural simplicity). Specific improvements were proposed in all the criteria analyzed.Originality/valueThe artifact can be considered a strategic guide for agtechs that have yet to overcome the barrier of initial conception of the business model. The model enables the identification of the main problems that agtechs can encounter in their life cycle, as well as seeking solutions in advance.
Industry talent branding: a collaborative and strategic approach to reducing hospitality’s talent challenge
Authors: Manoharan Ashokkumar , Scott-Young Christina , McDonnell Anthony 
Published: June 2023

PurposeThe COVID-19 pandemic exacerbated the talent challenges faced by hospitality organisations. This paper aims to propose a new concept – industry talent branding – which, is argued, offers industry stakeholders the opportunity to reduce such issues through working more collaboratively and strategically to magnify the pool in which individual organisations compete for talent.Design/methodology/approachThis paper proposes a conceptual framework of industry talent branding, based on brand equity theory, signalling theory and the employer branding literature.FindingsIndustry talent branding opens a potentially new stream of research on how talent attraction and retention issues may be addressed. The authors propose that there is merit in moving beyond the organisational-level phenomenon of employer branding to industry talent branding through articulating a broader collaborative and strategic agenda to increase and widen the talent pool available to organisations.Research limitations/implicationsThe proposed framework offers the hospitality industry and its encompassing stakeholders a means to adopt a more proactive, collective and strategic approach to address long-standing talent challenges.Originality/valueThis paper combines brand equity and signalling theories to develop the concept of industry talent branding, defined as a strategically curated, yet realistic impression of the employee value proposition (i.e. the benefits and rewards received by employees in return for their work performance) available within the industry, that by design will sustainably attract new employees into the industry and retain existing talent.
Shaping individual paths for decision-making: a fuzzy set approach of religious and humanistic beliefs leading to the (non)acceptance of euthanasia
Authors: Soares Maria Eduarda , Teixeira Alfredo , Tavares Patrícia 
Published: June 2023

Purpose
While the influence of individual beliefs on decision-making has been widely acknowledged, the interaction of different types of beliefs remains an under-researched topic. This study analyses how the simultaneous influence of religious beliefs and nonreligious beliefs shapes individual decision-making. This study aims to contribute to inform organizational decisions on topics potentially associated with these two types of beliefs, including corporate social responsibility matters. This study also aims to provide insights to ethical decision-making in situations of absence of social consensus, a subject that is relevant for individuals, organizations and policymakers.

Design/methodology/approach
This study uses fuzzy set qualitative comparative analysis to identify how different configurational groupings of Christian beliefs and humanistic beliefs lead to the acceptance or nonacceptance of euthanasia in a sample of individuals who identify as Catholic.

Findings
Among individuals sharing a Catholic religious affiliation, the authors identify three different configurations of beliefs – Cultural Catholics (religious beliefs are absent and humanistic beliefs are present), Observant Catholics (religious beliefs are present and humanistic beliefs are irrelevant) and Secular Catholics (both religious beliefs and humanistic beliefs are present).

Originality/value
Previous research has put forward the role of religion-related variables, such as religious affiliation and level of religiosity, for views on euthanasia. This study provides a more detailed analysis of the role of belief systems, identifying how different configurational groupings of beliefs lead to a decision grounded in moral and ethical considerations but for which there is an absence of social consensus.

Authors: Gupta Priyanka , Anand Adarsh , Tamura Yoshinobu , Ram Mangey 
Published: June 2023

PurposeThe ideology of this article is to study the performance concerns of SDN Controllers, with the help of developed SRGM and thereby obtain its optimal testing duration. The effect of undetected uncertainty in the parameter values have also been catered in the proposal.Design/methodology/approachThese uncertainties in the parameter values are studied as the risk of not meeting desired set of requirements, whose removal causes additional cost. Considering these two constructs as attributes of MAUT, the controller's optimal testing duration is obtained.FindingsThe article focuses towards obtaining the optimal duration for which the SDN Controllers must be tested. It was observed that the inculcation of risk-attribute has provided the higher utility value as compared to any other existing scenarios.Originality/valuePlenty of SRGM have been proposed in the literature which talks about the testing stop time determination problems. But, none of them have considered the impact of risk of not meeting the requirements (reliability) along with cost to obtain its testing stop time. Further, validation of the proposed model in presented with the help of two releases versions of SDN controller platform, ONOS, entitled as “Kingfisher” and “Loon” and has acquired promising results.
Does tourism flow in cities drive green practices in the current smart city trajectories? Empirical evidence from Italy
Authors: Marchesani Filippo , Masciarelli Francesca 
Published: June 2023

Purpose
The concept of a smart city is becoming more closely linked to tourism destinations. The relationship between the environment, sustainability and tourism has become more interrelated. An eco-friendly city environment can influence tourists’ decisions, but tourist flows can also negatively impact the local ecosystem by increasing energy consumption, air pollution and environmental sustainability. In this research letter, the authors reverse this perspective, moving into smart city trajectories, highlighting that increasing tourism in cities drives the city to advance a green transition to respond to the imbalance generated by large flows of tourists that increase the users-density of the city. Thus, the purpose of this study is to investigate the symbiotic relationship between increasing tourism in cities and the imperative for a green transition.

Design/methodology/approach
This study builds on the generalized method of moment approach and an 11-year panel data set covering 30 Italian cities to investigate the relationship between tourism flow and the cities’ green practices embedded in the smart environment dimension.

Findings
This study provides empirical evidence that a large flow of tourists in cities positively affects the cities’ green transition, contributing to the advancement of smart tourism and smart city debate.

Research limitations/implications
The study focuses only on one country, and although its results may be generalizable to the European Union, it is not representative at a global level and requires further research.

Practical implications
This study offers practical implications underscoring the benefits of large tourism inflow in managing and implementing smart city projects.

Social implications
Tourism and overtourism may lead to a city reaction regarding green practices, which can have a multiplier benefit on the urban environment.

Originality/value
To the best of the authors’ knowledge, this is one of the first study attempt to investigate the tourism flow as a driver of smart city implementation, considering the city’s reaction to tourism and overtourism conditions in the city that would lead to the ecological and sustainable collapse of a city.
“Does anyone know? Can you get any help?” Experiences from an ambassador-facilitated health programme: insights from a qualitative study
Authors: Bond Charlotte Brøgger , Stochkendahl Mette Jensen , Søgaard Karen , Andersen Lotte Nygaard 
Published: June 2023

PurposeHealth ambassadors are co-workers assigned to facilitate healthy choices amongst the ambassadors'' colleagues and are increasingly used in workplace health promotion. In a municipality in the southern region of Denmark, occupational health and safety (OHS) representatives were appointed as health ambassadors to facilitate the development of healthy lifestyle initiatives at the ambassadors' workplace and the uptake of various health offers from the municipality's workplace health programme amongst the ambassadors' colleagues. The aim of this study was to understand how employees and managers from the municipality experienced the health ambassador-facilitated implementation of the health programme.Design/methodology/approachThe study was designed as an interview study with (n = 13) semi-structured interviews. Using purposeful sampling, the authors invited participants who held different positions (e.g. managers and regular employees) on two different work teams in the municipality. The work teams (a construction team and a healthcare team) differed in gender profile and work tasks but were both categorised as physically heavy work. Malterud's systematic text condensation was used to devise the strategy for the analysis.FindingsThe authors' findings show that the employees considered health a private matter that the workplace should not interfere with, and this challenged the implementation of the health programme. Secondly, the health ambassadors were not properly trained to facilitate health initiatives amongst the ambassadors' colleagues; instead, the managers were the driving force in the implementation of health initiatives.Originality/valueThe study provides useful insights into the processes of implementing health in the workplace and emphasises the importance of involving employees in design and planning of initiatives for workplace health promotion.
How does material adaptivity of smart objects shape infusion use? The pivot role of social embeddedness
Authors: Hu Qian , Pan Zhao , Lu Yaobin , Gupta Sumeet 
Published: June 2023

PurposeAdvances in material agency driven by artificial intelligence (AI) have facilitated breakthroughs in material adaptivity enabling smart objects to autonomously provide individualized smart services, which makes smart objects act as social actors embedded in the real world. However, little is known about how material adaptivity fosters the infusion use of smart objects to maximize the value of smart services in customers' lives. This study examines the underlying mechanism of material adaptivity (task and social adaptivity) on AI infusion use, drawing on the theoretical lens of social embeddedness.Design/methodology/approachThis study adopted partial least squares structural equation modeling (PLS-SEM), mediating tests, path comparison tests and polynomial modeling to analyze the proposed research model and hypotheses.FindingsThe results supported the proposed research model and hypotheses, except for the hypothesis of the comparative effects on infusion use. Besides, the results of mediating tests suggested the different roles of social embeddedness in the impacts of task and social adaptivity on infusion use. The post hoc analysis based on polynomial modeling provided a possible explanation for the unsupported hypothesis, suggesting the nonlinear differences in the underlying influencing mechanisms of instrumental and relational embeddedness on infusion use.Practical implicationsThe formation mechanisms of AI infusion use based on material adaptivity and social embeddedness help to develop the business strategies that enable smart objects as social actors to exert a key role in users' daily lives, in turn realizing the social and economic value of AI.Originality/valueThis study advances the theoretical research on material adaptivity, updates the information system (IS) research on infusion use and identifies the bridging role of social embeddedness of smart objects as agentic social actors in the AI context.
Self-perceived employability of undergraduate students during the COVID-19 pandemic: the role of traits, knowledge sharing and trust
Authors: Nguyen Duong Tuan , Nguyen Thi Ngoc Hoai , Luu Van Binh , Bui Van Khanh , Nguyen Tra My 
Published: June 2023

PurposeThis study aims to explore the impact of personality traits on self-perceived employability (SPE) and test if the associations are mediated by knowledge sharing (KS) through online learning during the COVID-19 pandemic. In addition, the moderation effect of trust in the relationship between KS and SPE was examined.Design/methodology/approachBased on Big Five Personality Trait Model and KS model, the authors proposed and tested the research framework with 341 samples collected from university students who experienced online learning during the social distancing caused by the COVID-19 pandemic. The measurement model was assessed to confirm the validity and reliability of the structure, then hypothesis testing was performed with the partial least square-structural equational model (PLS-SEM).FindingsThe results showed that extraversion and agreeableness positively affected SPE through KS. Moreover, trust played a moderating role on the effect of KS on SPE.Practical implicationsBased on the research findings, the authors suggest that academic institutions, especially universities, should provide opportunities for students to explore their personality traits. Second, the university should organize specific activities that promote knowledge sharing among students. Third, the university should encourage the creation of platforms aimed at sharing knowledge in a reliable way that increases trust in responsiveness.Originality/valueThe present study contributes to the literature on SPE by presenting immediate empirical evidence on the relationship between personality traits and SPE, along with mediating and moderating effects. These findings provide meaningful implications for higher education institutions that implement online learning during challenging circumstances.
Transformative leadership conversation: a conceptualization and empirical test of its function
Authors: Adams Curt , Adigun Olajumoke Beulah , Fiegener Ashlyn , Olsen Jentre J. 
Published: June 2023

PurposeThe study begins by defining and conceptualizing Transformative Leadership Conversation (TLC). The conceptualization addresses the meaning of transformation, sensemaking and learning dialogue, and the conversation structures of framing, questioning and listening, and affirming. Next, the authors build a theoretical argument from self-determination theory on the function of TLC. The study concludes with an empirical test of the structure and function of TLC.Design/methodology/approachThere were two parts to the empirical study. First, the authors designed and tested a scale to measure TLC by its structural features (e.g. questioning, listening and affirming language). Second, the authors used a correlational design with ex-post facto data to test the primary assumption that TLC activates autonomous motivation and action. Data came from a random sample of 2,500 teachers in a southwestern state. Useable responses were obtained from 1,615 teachers, for a response rate of 65%.FindingsThe empirical tests reveal that the 12-item and 6-item measure of the School Leader Transformative Conversation Scale present valid and reliable evidence on the frequent use of TLC. Consistent with the hypothesized model, TLC had a direct, positive relationship with teacher vitality. It also had a negative relationship with autonomy frustration and a positive indirect effect on teacher vitality by reducing the negative effect of autonomy frustration.Originality/valueTLC advances a new conceptual lens to study school leadership as a discursive process. The concept opens lines of inquiry that have not yet been examined in school settings.
