Abstract
Purpose
The purpose of this paper is to investigate changes in, and associations between, sense of coherence (SOC) and emotional distress in women who participated in an accredited motivational program (VINN) in correctional institutions in five countries.
Design/methodology/approach
A prospective study with a pre- and post-test design included 316 participants from Sweden, Estonia, Denmark, Russia and Norway. Global emotional distress was measured by the Hospital Anxiety and Depression Scale. SOC was measured using the 13-item Orientation to Life Questionnaire. One-way analysis of variance and multilevel regression models were used in the statistical analyses.
Findings
An increase in SOC was associated with a decrease in emotional distress. Emotional distress decreased significantly −3.80 points (95 percent CI (−4.61, −2.97)), and SOC significantly improved from pre- to post-measurement by 1.82 points (95 percent CI (0.72, 2.92)), regardless of country and correctional institution.
Practical implications
The results add new knowledge regarding a coherent theoretical foundation of a motivational program for women. The ability of a program promoting health is important for researchers, health-care workers and facilitators delivering programs for women in correctional facilities. An increase in SOC can act as a protective factor in order to manage stressors and risk factors among women serving in correctional facilities.
Originality/value
The present study indicates that enhancing women’s coping resources and providing income alternatives to crime is fundamental to their capacity to desist from criminal behavior.

Abstract
Purpose
This study aims to examine the associations of social networks with the sense of community (SOC) construct and spatial colocation or having an office. The study site was an institute for health-care policy research formed in 2011 by bringing together scientists from more than 20 different university units. Only 30% of the scientists were had an office or physical presence at the institute. Therefore, the institute was an ideal site to examine whether SOC was correlated with different dimensions of network position – connectedness, reachability and brokerage – even when the authors account for the lack of spatial colocation for the off-site scientists.
Design/methodology/approach
A two-part (sociometric and workplace) internet survey instrument was administered in 2014 to the institute’s population of 411 individuals. The sociometric data were used to create an undirected interaction network and the following dependent variables (DVs) or network centralities: normalized degree to measure connectedness; average reciprocal distance to capture reachability; and normalized betweenness to proxy brokerage. Separate node-level network regressions were then run with random permutations (N = 10,000) and listwise deletion for each of the DVs with SOC and spatial colocation as the independent variables, and variables that controlled for gender, organizational affiliation and job category.
Findings
SOC and spatial colocation are both positively and significantly correlated with network connectedness and reachability. The results suggest that both SOC and spatial colocation have a larger impact on reachability than connectedness. However, neither SOC nor spatial colocation are significantly associated with network brokerage. Finally, the findings show that SOC and spatial colocation are more reliable predictors of network connectedness and reachability than are key individual- and unit-level control variables, specifically the individual’s sex, job category and organizational affiliation. The controls were not significantly associated with any of the three network centralities, namely, connectedness, reachability and brokerage.
Originality/value
This exploratory study used social network analysis and node-level network regressions to examine the associations from SOC and spatial colocation to dimensions of network position. SOC is positively and significantly associated with network connectedness and reachability, suggesting that SOC is an important consideration when individuals are disadvantaged from the absence of spatial colocation. The findings have implications for work in the context of the COVID-19 pandemic as they imply that interventions based on the SOC construct could potentially lessen the negative effects of remote work on workplace social networks due to factors such as the reduction of social contacts.

Abstract
Purpose
The operation state of lithium-ion battery for vehicle is unknown and the remaining life is uncertain. In order to improve the performance of battery state prediction, in this paper, a joint estimation method of state of charge (SOC) and state of health (SOH) for lithium-ion batteries based on multi-scale theory is designed.
Design/methodology/approach
In this paper, a joint estimation method of SOC and SOH for lithium-ion batteries based on multi-scale theory is designed. The venin equivalent circuit model and fast static calibration method are used to fit the relationship between open-circuit voltage and SOC, and the resistance and capacitance parameters in the model are identified based on exponential fitting method. A battery capacity model for SOH estimation is established. A multi-time scale EKF filtering algorithm is used to estimate the SOC and SOH of lithium-ion batteries.
Findings
The SOC and SOH changes in dynamic operation of lithium-ion batteries are accurately predicted so that batteries can be recycled more effectively in the whole vehicle process.
Originality/value
A joint estimation method of SOC and SOH for lithium-ion batteries based on multi-scale theory is accurately predicted and can be recycled more effectively in the whole vehicle process.

Abstract
Prediction of increased risk of suicide is difficult. We had the opportunity to follow up 20 patients receiving electroconvulsive therapy (ECT) because of severe depression. They filled in the Antonovsky sense of coherence test (SOC) and Beck depression inventory (BDI) before and after a series of ECT treatments. Seventeen surviving patients had a mean observation time of 20.6 months, whereas the three deceased patients had 11.3 months. There was a lower mean age at onset of illness and a longer mean duration of disease in the deceased. Other clinical parameters did not differ. The surviving patients had a significant decrease on the BDI from 35 to 18 (P<0.001) and an increase on the SOC test after ECT from 2.45 to 3.19 (P<0.001), indicating both less depression and better functioning in life. The deceased had a larger change on the BDI from 32 to 13, not attaining significance because of the low number of deceased. The SOC test, however, did not increase to a purported normal level; that is, from 2.43 to 2.87. Although the SOC scale has been shown to predict mortality in substance abusers, the SOC test has not been part of earlier reviews of predictive power. Tentatively, a low pathological score on the SOC test may indicate low sense of coherence in life that might increase the propensity for suicide. These preliminary results need replication in larger studies.

This study aimed to investigate the mechanisms of knowledge brokering and role crafting structures that promote the active engagement of older workers at work.
Abstract
Purpose
This study aimed to investigate the mechanisms of knowledge brokering and role crafting structures that promote the active engagement of older workers at work.
Design/methodology/approach
The respondents were workers in Japan aged 55–64 years. A two-wave panel survey was conducted. The first and second survey waves included 1,527 and 1,467 respondents, respectively.
Findings
The results showed that knowledge brokering positively influenced work engagement directly and indirectly. In the three dimensions of role crafting, cognitive and task crafting had a positive effect on work engagement.
Research limitations/implications
This study focused on older workers in Japan. Therefore, it is necessary to verify whether the same effect is observed in countries other than Japan or among younger workers.
Practical implications
On an individual level, older workers should aim to keep acquiring new information inside and outside the organisation. On an organisational level, it is effective to increase opportunities for older workers to craft their work according to the socioemotional selectivity and selection optimisation and compensation theories.
Originality/value
This study reveals that knowledge brokering and cognitive crafting in role crafting have an important influence on the work engagement of older workers. Additionally, this study clarifies the impact of job crafting on older workers not only from the perspective of resource crafting to achieve person-job fit but also from the perspective of reframing perceptions through cognitive crafting in role crafting. These findings enable a clearer understanding of the relationship between role crafting and knowledge brokering, as well as the socioemotional selectivity and selection optimisation and compensation theories.

The purpose of this study is to develop an optimization method for charging plans with the implementation of time-of-day (TOD) electricity tariff, to reduce electricity bill.
Abstract
Purpose
The purpose of this study is to develop an optimization method for charging plans with the implementation of time-of-day (TOD) electricity tariff, to reduce electricity bill.
Design/methodology/approach
Two optimization models for charging plans respectively with fixed and stochastic trip travel times are developed, to minimize the electricity costs of daily operation of an electric bus. The charging time is taken as the optimization variable. The TOD electricity tariff is considered, and the energy consumption model is developed based on real operation data. An optimal charging plan provides charging times at bus idle times in operation hours during the whole day (charging time is 0 if the bus is not get charged at idle time) which ensure the regular operation of every trip served by this bus.
Findings
The electricity costs of the bus route can be reduced by applying the optimal charging plans.
Originality/value
This paper produces a viable option for transit agencies to reduce their operation costs.

Abstract
Purpose
The purpose of this paper is to show the relevance attributed to sustainability management control tools (SMCTs) and their real use. Mainly, this study aims to shed light on the approaches, motivations and difficulties encountered in SMCTs adoption by the most sustainable Italian companies, as well as their effectiveness.
Design/methodology/approach
Using a pre-structured qualitative survey method, the authors grasped information about external and internal dimensions of sustainability management in light of institutional and resource-based view theories. Data are elaborated with two methods: a regime analysis to assess the relevance of SMCTs and a descriptive analysis to investigate the “aim”, “which” and “how” of the SMCTs' use by companies listed in sustainability indices.
Findings
Informal SMCTs prevailed over formal ones. There is a discrepancy between attention paid to some tools praised in the literature and their knowledge and use. In addition, a significant gap exists between what is desired and what is achieved in terms of effectiveness. Further, although sustainability management is primarily oriented towards the external perspective, SMCTs can be key to improving both the disclosure and management of sustainability.
Research limitations/implications
The criteria for the selection of the sample resulted in a small number of analysed companies, which allowed us to gain insight into what happens inside the listed Italian companies in the most important sustainability indices. These companies have sustainability-oriented management, which also probably safeguards their advantage linked to inclusion in these indices.
Practical implications
This paper provides food for thought for companies engaged in non-financial disclosure and for those who aim to implement SMCTs. It shows the need to reinforce formal sustainability control tools, also through dissemination of major knowledge about the implementation of these tools, and to encourage sponsorship from top levels of management.
Originality/value
Compared with SMCT research using a theoretical or case study approach, this study uniquely undertakes extensive research on the perceived effectiveness of SMCTs in achieving sustainability goals and the difficulties in implementing them, thereby highlighting a discrepancy between some tools emphasised in the literature and those infrequently used in sustainability-oriented companies.

Abstract
Purpose
How can social presence, participation and a sense of community be formed in an online setting without compromising on social connectedness through physical distancing? Under consideration of the goals for an Education for Sustainable Development, transformative science and the social techniques of Theory U, developed by Otto Scharmer (2016), an online Community of Inquiry of researchers, practitioners and learners was to be developed, followed and observed to discuss the question whether and how it was possible to create an awareness-based, future-oriented and socially committed online community that would enrich social transformation processes.
Design/methodology/approach
Methods of 1st, 2nd and 3rd person research were applied, as well as group discussions, one Mentimeter survey and one standardised questionnaire with an open question.
Findings
Results indicate that it is not only possible to create a feeling of community in an online setting, but also point to the terms and conditions which act as enablers and influencers, like seeing each other face-to-face, collective check-ins and check-outs as well as small group break-out sessions. Video conferencing and the practicing of rules of conduct and communication, also referred to as netiquette, enable a transcendence of the physical distance to reach a feeling of belonging and social presence in the perception of the participants.
Originality/value
In line with global sustainable development, the study also sets an example for how to reduce personal emissions when planning an international conference. Also, it shows how to create online spaces to connect people worldwide, which will support to take over responsibilities as world citizens.

Abstract
Purpose
This study aims to investigate the impact of environmental performance, social responsibility and corporate governance (ESG) on bank performance (BP) in the Italian banking sector. It analyzes the relationships between 10 dimensions of ESG pillars and BP indicators during the period 2016–2020.
Design/methodology/approach
This study examines a sample of 105 Italian banks and develops three econometric models to verify the effect of ESG initiatives on BP indicators. The independent variables are the ESG dimensions collected from the Refinitiv database, whereas the explanatory variables are performance indicators measured through accounting and market variables.
Findings
The findings show that ESG policies negatively affect operational and market performance in the banking sector, suggesting that Italian banks have not fully embraced strong sustainability procedures. However, the relationships between ESG dimensions are mixed if measured individually. The results show a significant positive impact of emission and waste reductions on financial and operating performance, but regarding social aspects, it is proved that better product responsibility decreases accounting performance.
Research limitations/implications
This study offers an in-depth examination of ESG practices in relation to current and future performance. In particular, the findings provide practitioners and academics with an actual set of predictors in the ESG area to improve BP.
Originality/value
To the best of the authors’ knowledge, this is the only study that has investigated the impact of ESG issues on BP in Italy. Few prior studies have used all dimensions of ESG policies at a disaggregated level to investigate their effect on various performance indicators.

Abstract
Purpose
The purpose of this paper is to optimize the design of charging station deployed at the terminal station for electric transit, with explicit consideration of heterogenous charging modes.
Design/methodology/approach
The authors proposed a bi-level model to optimize the decision-making at both tactical and operational levels simultaneously. Specifically, at the operational level (i.e. lower level), the service schedule and recharging plan of electric buses are optimized under specific design of charging station. The objective of lower-level model is to minimize total daily operational cost. This model is solved by a tailored column generation-based heuristic algorithm. At the tactical level (i.e. upper level), the design of charging station is optimized based upon the results obtained at the lower level. A tabu search algorithm is proposed subsequently to solve the upper-level model.
Findings
This study conducted numerical cases to validate the applicability of the proposed model. Some managerial insights stemmed from numerical case studies are revealed and discussed, which can help transit agencies design charging station scientifically.
Originality/value
The joint consideration of heterogeneous charging modes in charging station would further lower the operational cost of electric transit and speed up the market penetration of battery electric buses.
