Published: August 2021

AbstractLiving cells are neither perfectly elastic nor liquid and return a viscoelastic response to external stimuli. Nanoindentation provides force distance curves allowing the investigation of cell mechanical properties, and yet, these curves can differ from point to point on cell surface revealing its inhomogeneous character. In the present work, we propose a mathematical method to estimate both viscoelastic and noise properties of cells, as these are depicted on the values of the scaling exponents of relaxation function and power spectral density respectively. The method uses as input the time derivative of the response force in a nanoindentation experiment. Generalized moments method and/or rescaled range analysis are used to study the resulting time series depending on their non-stationary or stationary nature. We conducted experiments in livingUlocladium Chartarumspores. We found that spores, in the approaching phase present a viscoelastic behavior with the corresponding scaling exponent in the range 0.25-0.52, and in the retracting phase present a liquid-like behavior with exponents in the range 0.67-0.85. This substantial difference of the scaling exponents in the two phases suggests the formation of biomemory as response of the spores to the indenting AFM mechanical stimulus. The retracting phase may be described as a process driven by bluish noises, while the approaching one is driven by persistent noise.
Impressions about people with intellectual disability of polish high school students who participated in a workshop led by self-advocates
Authors: Nowakowska Iwona , Pisula Ewa 
Published: August 2021

Purpose
The aim of the paper is to assess whether participation in a two-session workshop led by self-advocates with mild intellectual disability (ID), supported by professional staff, affects high school students’ impression of people with ID, measured by a self-report questionnaire based on a semantic differential.

Design/methodology/approach
The study was paper-pencil questionnaire-based and anonymous, conducted in Warsaw, Poland. Three measurements were performed using two semantic differentials – two weeks before the workshop, one day and three months afterward. In total, 50 high school students in the workshop group and 43 students in the control group took part in the study.

Findings
After the workshop, people with ID were perceived as more calm, compliant and adult and this change was not observed in the control group.

Research limitations/implications
The picture of people with ID after the workshop may probably have been even more complex than before. However, the study focuses on a specific intervention and does not include data about other, similar meetings led in another school and by other self-advocates.

Practical implications
It is worthy to design anti-discriminatory workshops led by the self-advocates to impact the perceptions of people with ID. The particular intervention would benefit from alterations.

Social implications
Workshops performed by self-advocates with ID may be promising in terms of limiting stereotype formation in target groups of workshops.

Originality/value
This research fills the gap in the longitudinal studies on the changes in the impressions about people with ID following an intervention based on personal contact.
An apposite framework for green cities development in developing countries: the case of Ghana
Authors: Debrah Caleb , Owusu-Manu De-Graft 
Published: August 2021

Purpose
The purpose of this study is to develop a framework to guide green cities development in developing countries. The study adapted and validated indicators that can be adopted, to predict, estimate, depict and measure green city development in developing countries. In using a covariance-based structural equation model (CBSEM), the study developed a framework for green cities development in developing countries using Kumasi city (Ghana) as a case study.

Design/methodology/approach
To test the proposed framework, a quantitative methodology was used, in which, data was collected using research questionnaires that targeted a sample of 200 green city experts. In total, 154 useable questionnaires were retrieved, representing a response rate of 77%. The confirmatory and exploratory factor analyses were adopted in a CBSEM.

Findings
The indices reported were indicative that the model/framework is a good fit for the data. This points to the direction that the model for measuring green city development was statistically significant and acceptable. The results of the confirmatory factor analysis revealed a robust fit of the indices, as they met the standardised cut-off points and as such the model fits the data.

Practical implications
This novel research is one of the few studies investigating green cities development in Ghana which could serve as a lesson for other developing countries. The proposed green city framework will serve as a guide to stakeholders in identifying the key indicators/factors that are critical to green city development in developing countries, especially Ghanaian cities.

Originality/value
This study proposed a green city framework to guide the development of green cities based on the local context of Ghana.
No good deed is too small: field experimental studies of different self-identities and workplace saving behavior
Authors: Zhou Jinyi , Chi Wei , Zhu Weichun 
Published: August 2021

Purpose
This paper aims to propose that the extent to which activating self-identity increases resource-saving behavior varies across these three levels of self-identities. In particular, the authors hypothesize that activating relational or collective self-identity increases saving behavior more than activating individual self-identity does. Moreover, activating relational self-identity has a stronger impact on workplace saving behavior than activating collective self-identity does. In addition, the authors suggest that prosocial motive mediates the relationship between the three levels of self-identity and saving behavior.

Design/methodology/approach
Workplace saving behavior such as office supply savings could help save organizational resources and build more environmentally conscious organizations. Drawing from self-identity theory, the authors examine the influences of three types of self-identities (i.e. individual, relational and collective self-identities) on workplace resource-saving behaviors.

Findings
The results obtained from a field experiment conducted in a Chinese company and an online vignette study generally support the proposed hypotheses. The authors also discuss the theoretical and practical implications of the findings.

Originality/value
The authors contribute to the literature on saving behavior in organizations by studying an individual-level predictor from the perspective of self-identity and the research on self-identity and saving behavior by testing the mediating role played by prosocial motive. Based on the findings, the authors also propose some human resource policies to increase workplace saving behavior.

Authors: Amos Daniel , Au-Yong Cheong Peng , Musa Zairul Nisham 
Published: August 2021

PurposeWith rising health-care costs and the financial constraints in most developing countries, prioritization of needs have become an issue of strategic importance in public hospitals. As a result, there is the intense competition of scare resources between core health care and non-core facilities management (FM) services. Given that financial resources are needed to facilitate the smooth operation of the FM department, this paper aims to investigate the direct and indirect effects of finance on the relationship between service quality and performance of hospital FM services.Design/methodology/approachThe paper adopts a quantitative approach following a general questionnaire survey which was conducted on the research population. Partial least squares structural equation modelling was used to investigate the relationships between service quality and performance of hospital FM services.FindingsThe study highlights the relevance of service quality to improving FM performance and demonstrate the direct and indirect influence of finance to ensure quality FM services delivery to improve core health care outcomes in hospitals.Practical implicationsThe result of this study should motivate hospital management to prioritize attention on FM in scare resources management in public hospitals to create and maintain a decent health-care environment for better health outcomes. Further, managerial commitment to facilitate employee training, empowerment, incentives, awards and compensation should be strengthened in the quest of ensuring quality services delivery.Originality/valueThe paper extends knowledge by mediating the influence of finance on the relationship between service quality and FM performance. Proposes a parsimonious financial mediation framework which can easily be adaptable to several developing countries health-care FM management.
Response to a phishing attack: persuasion and protection motivation in an organizational context
Authors: Bayl-Smith Piers , Taib Ronnie , Yu Kun , Wiggins Mark 
Published: August 2021

Purpose
This study aims to examine the effect of cybersecurity threat and efficacy upon click-through, response to a phishing attack: persuasion and protection motivation in an organizational context.

Design/methodology/approach
In a simulated field trial conducted in a financial institute, via PhishMe, employees were randomly sent one of five possible emails using a set persuasion strategy. Participants were then invited to complete an online survey to identify possible protective factors associated with clicking and reporting behavior (N = 2,918). The items of interest included perceived threat severity, threat susceptibility, response efficacy and personal efficacy.

Findings
The results indicate that response behaviors vary significantly across different persuasion strategies. Perceptions of threat susceptibility increased the likelihood of reporting behavior beyond clicking behavior. Threat susceptibility and organizational response efficacy were also associated with increased odds of not responding to the simulated phishing email attack.

Practical implications
This study again highlights human susceptibility to phishing attacks in the presence of social engineering strategies. The results suggest heightened awareness of phishing threats and responsibility to personal cybersecurity are key to ensuring secure business environments.

Originality/value
The authors extend existing phishing literature by investigating not only click-through behavior, but also no-response and reporting behaviors. Furthermore, the authors observed the relative effectiveness of persuasion strategies used in phishing emails as they compete to manipulate unsafe email behavior.

Authors: Bankuoru Egala Sulemana , Boateng Dorcas , Aboagye Mensah Samuel 
Published: August 2021

PurposeIn this paper, the authors investigated the impact of quality digital banking services delivered during the COVID-19 pandemic on customers' satisfaction and retention intentions.Design/methodology/approachThis study combined constructs drawn from the E-S-QUAL and BSQ models to measure the impact of digital banking services on subscribers of digital banking services in Ghana. The study utilized structural equation modeling with partial least squares (PLS-SEM) to analyze 395 responses.FindingsResults revealed a significant direct effect between digital banking services satisfaction and customer retention decision. The results also revealed that digital banking services quality dimensions such as ease of use, efficiency, privacy/security and reliability impact customers' satisfaction and retention intentions.Research limitations/implicationsDigital banking service portfolios and their quality dimensions vary among banks. This offers an opportunity for banking institutions and other non-bank financial service providers to be wary of the impact of quality service delivery on customers' decisions. This paper makes significant theoretical contributions and practical implications on the relevance of quality digital banking services in customers' retention strategies for competitive advantage.Originality/valueThis study has underlined the significance of quality digital banking services in developing countries. The study underscored the need for banking and non-bank financial institutions to embrace the much-anticipated quality service demanded by customers and the need for continuous service improvement relative to the growing deployment of financial technologies.
Conflict resolution practice in public procurement: evidence from Russia
Authors: Rodionova Yuliya 
Published: August 2021

PurposeThis paper aims to analyze conflict resolution practice in public procurement. The specific feature of this sphere is the presence of the state and the resulting differences in assessing the chances of protecting one’s interests in court, as well as the effectiveness of judicial conflict resolution mechanisms.Design/methodology/approachThis paper is based on the findings of a large-scale survey of suppliers conducted in 2017. To identify the characteristics of suppliers that use different conflict resolution mechanisms, probit-models were evaluated. For robustness check, combined mechanisms for resolving conflict situations were also considered and multi-nomial logistic regression was used.FindingsThe survey results showed that the majority of suppliers prefer to resolve conflicts in public procurement using an out-of-court negotiation with procurers while only 31% of respondents resort to judicial proceedings. At the same time, suppliers potentially involved in informal relations with procurers, are less likely to go to court and less often use negotiations.Practical implicationsThe results of the study can be used as a justification for the development of a regulatory and organizational framework for the use of negotiations, mediation, arbitration and other alternate methods of conflict resolution in public procurement.Originality/valueThis paper makes an important contribution to the conflict-handling strategies of businesses and government by presenting for the first time a quantitative assessment of the prevalence of mechanisms for resolving conflicts in public procurement and factors influencing the choice of a conflict resolution mechanism.
Impact of own resources on municipalities’ investments expenditures in Benin
Authors: Hounmenou Bernard G. , Degbedji Fabrice D. 
Published: August 2021

Purpose
This paper aims to study the impact of municipalities’ own resources on their investments‘ expenditure.

Design/methodology/approach
Panel data analysis. A sample of 34 municipalities in Benin. Econometrics tests for the panel data models – estimation of the fixed-effect and random-effect models. Hausman test to identify the best model to explain the impact of the explanatory variables on local investments’ expenditures. Heteroskedasticity, normality and autocorrelation tests.

Findings
The results establish a positive and significant impact of own resources, state transfers and demographic variables on local investments’ expenses.

Research limitations/implications
As an implication, the results show the importance of local resources’ mobilization for the municipalities’ investment capacity building. They also show that the central government transfers continue to play a major place in local investments’ finance, even in a decentralization context. Limitation: Available data do not allow to well evaluate the impact of the electoral variable on municipalities’ investments’ expenditure. This situation does not allow to well analyze the public choice considerations in local authorities’ behaviors.

Practical implications
Local mobilization of financial resources must be encouraged to raise municipalities’ investments’ capacities. Strategies must be developed to reinforce local capacities in local resources mobilization.

Social implications
The results show the importance of local resources in local investments. They show the importance of citizens’ participation in their well-being construction, through local resource mobilization (ex: local fiscality).

Originality/value
Many authors assert in the literature that financial autonomy has a real impact on local development. However, empirically, it was not demonstrated. This paper contributes to correct this lack.
A risk model to compute the volatility and the need for collateral margins in energy futures contracts in Brazil
Authors: Argento Pedro , Klotzle Marcelo Cabus , Figueiredo Pinto Antonio Carlos , Gomes Leonardo Lima 
Published: August 2021

Purpose
Brazil is characterized by the inexistence of a more robust system of guarantees and rules to minimize risks and protect agents in energy futures contracts. In this sense, this study aims to answer the question of how a centralized clearing agent can compute safety margin requirements to help reduce the systemic risk of the energy futures contracts market in Brazil.

Design/methodology/approach
The intermediate steps and specific objectives are to analyze the volatility behavior, identify the autoregressive conditional heteroscedasticity effects and model the variance of the return series. Based on this, the authors calculate the value-at-risk and conditional value-at-risk metrics for the energy futures contracts. As a robustness test, the authors added a peak over threshold methodology from extreme values theory.

Findings
In general, monthly products require margins because of their higher variance. With the asymmetrical distribution of returns, the authors needed to consider different maintenance margins for the long and short positions. It was also shown that two guarantee margins were required to secure the contracts as follows: the initial margin and the maintenance margin. The three factors that defined the size of the maintenance margin the volatility, skewness and kurtosis of the return series.

Originality/value
The contribution of this study lies in promoting the understanding of the risk dimensions of the energy derivatives market in Brazil and it offers concrete recommendations for how to mitigate this risk through market mechanisms and structures. Similar arrangements can be applied to other emerging markets.
Towards emancipation through organizational (re)design? Exploring integral organizational renewal from a critical management perspective
Authors: Gronouwe Lucas , Moorkamp Matthijs , Visser Max 
Published: August 2021

Purpose
The purpose of this paper is to contribute to a more pragmatic critical management studies (CMS), by exploring the emancipatory intent of organizational (re)design concepts and ideas from the modern sociotechnical approach integral organizational renewal (IOR).

Design/methodology/approach
This paper is of a conceptual nature in that it engages with relevant literature from the fields of CMS and IOR, guided by a focused conceptualization of emancipation from CMS literature.

Findings
It is found that although IOR can to a large extent be considered as an emancipatory project, it contains a number of dangers which jeopardize its emancipatory potential. Complemented with other sociotechnical approaches and ideas, however, it appears that IOR could make some valuable contributions to a pragmatic CMS.

Originality/value
This paper is unique in engaging in an exchange of ideas between CMS and IOR. By doing so, it contributes, first, to the debate on a more pragmatic CMS; second, to the dialogue between CMS and “mainstream” organization science; third, to the field of organizational (re)design.
The role of age structure and occupational choices in the Indian labour market
Authors: Kumar Dhananjay , Bisht Nitin , Kumar Indrajeet 
Published: August 2021

PurposeThis study aims to identify the role of age structure in occupational choices and the classification of the occupations based on the age structure of individuals in the Indian labour market.Design/methodology/approachThis study uses the first Periodic Labour Force Survey, 2017–18. The occupational classifications are based on the standardised scores for age groups and their occupations. Further, a multinomial logistic regression model has been used to estimate social and economic factors in determining the age-based occupational classifications.FindingsThe authors found age structure an essential factor in determining occupational choices. Hence, occupations in the Indian labour market have been grouped into seven categories, accordingly. In addition, social and economic factors of individuals and households do have a significant influence on the selection of age-based occupational classifications.Research limitations/implicationsThe study is limited to the occupational classification based on the age structure of individuals without any industry effects. The findings suggest that policymakers must adopt occupation-specific policies considering the age structure of individuals.Originality/valueEarlier studies are limited to the dynamics of age either on the basis of specific age groups (younger or older) or on the industrial classification in a disaggregated way. They also lack a rich approach in analysing the occupational classification considering age structure, especially in the Indian labour market. The study adds value when the role of age structure is identified in occupational choices in the Indian labour market, and hence, a novel classification of occupations into seven categories is proposed.
From environmental education to education for sustainable development in higher education: a systematic review
Authors: Acosta Castellanos Pedro Mauricio , Queiruga-Dios Araceli 
Published: August 2021

Purpose
In education concerning environmental issues, there are two predominant currents in the world, environmental education (EE) and education for sustainable development (ESD). ESD is the formal commitment and therefore promoted by the United Nations, to ensure that countries achieve sustainable development. In contrast, EE was the first educational trend with an environmental protection approach. The purpose of this systematic review that seeks to show whether the migration from EE to ESD is being effective and welcomed by researchers and especially by universities is presented. With the above, a global panorama can be provided, where the regions that choose each model can be identified. In the same sense, it was sought to determine which of the two currents is more accepted within engineering education.

Design/methodology/approach
The review followed the preferred reporting items for systematic reviews and meta-analyzes parameters for systematic reviews. In total, 198 papers indexed in Scopus, Science Direct, ERIC and Scielo were analyzed. With the results, the advancement of ESD and the state of the EE by regions in the world were identified.

Findings
It was possible to categorize the geographical regions that host either of the two EE or ESD currents. It is important to note that ESD has gained more strength from the decade of ESD proposed by the United Nations Educational, Scientific and Cultural Organization. For its part, EE has greater historical roots in some regions of the planet. In turn, there is evidence of a limited number of publications on the design and revision of study plans in engineering.

Originality/value
Through this systematic literature review, the regions of the world that are clinging to EE and those that have taken the path of ESD could be distinguished. Moreover, specific cases in engineering where ESD has been involved were noted.
