Abstract
Purpose
The purpose of this paper is to describe the design and development of “Pylon-Climber”, a pole climbing robot (PCR) for climbing along the corner columns of electricity pylon and assisting the electricians to complete maintenance tasks.
Design/methodology/approach
Introduces a PCR that is composed of a simple climbing mechanism and two novel grippers. The gripper consists of two angle-fixed V-blocks, and the size of V-block is variable. The clamping method of the angle bar meets the requirement of the force closure theorem. The whole design adopts symmetrical design ideas.
Findings
The developed prototype proved possibility of application of PCRs for inspection and maintenance of pylon. The novel gripper can provide enough adhesion force for climbing robot.
Practical implications
The robot is successfully tested on a test tower composed of different specification steel angles, oblique ledges and overlapping steel struts.
Originality/value
Design and development of a novel climbing assistive robot for pylon maintenance. The robot is able to climb along the column of electricity pylon and pass all obstacles. The gripper can reliably grasp the angle bar with different specification and overlapping steel struts from multiple directions.

Abstract
Purpose
This paper aims to analyze the extent to which education for sustainable development (ESD) training enhances university teachers’ professional competence and whether it has the same effect in the digital as in the face-to-face format.
Design/methodology/approach
A training concept was developed based on the professional action competence model. Between 2018 and 2021, 19 training sessions were conducted with 183 university teachers: ten in face-to-face sessions and nine in the digital format. Questionnaires were administered before and after the training to determine its impact.
Findings
Overall, the training proved to be effective. There was a significant increase in professional knowledge and self-efficacy after the training, but there was no change in motivation. The face-to-face and digital formats proved to be equally effective.
Research limitations/implications
The long-term effect of the training could not be determined.
Practical implications
There should be regular ESD training and coaching for university teachers.
Originality/value
There has been little research on the effectiveness of ESD teacher training, and no comparison between the face-to-face and digital approaches exists. It has been possible to train a relatively large number of university teachers from a wide range of subject areas, about two-thirds of whom have had no previous ESD experience.

Abstract
Purpose
This study aims to outline the influence of various combinations of antecedent conditions for startups being accepted into business incubators in Italy and Romania. The degree to which these conditions affect acceptance is referred to here as the Business Ideas Acceptance Degree (BIAD). The antecedent conditions considered are business idea potential, business plan quality, entrepreneurial team features, business project progress stage, available financial resources, debts of potential incubated companies, commitment to apply for national/EU funds, business area related to incubator mission, proposed technological content level, technological transfer from university/research centres and spin-off of a partner-entity of the incubator.
Design/methodology/approach
The methodological toolkit used was mixed: correlation-based analysis (CBA), machine learning (ML) techniques and fsQCA. Principal component analysis enabled the selection of the most representative antecedent conditions from both business incubator samples in Italy and Romania, further used in fsQCA analyses. XGBoost algorithm has been also used. K-Means clustering, an unsupervised learning algorithm that groups unlabeled dataset into different clusters, led to the configuration of two clusters associated to each of the countries involved in this study (Romania and Italy).
Findings
The findings reveal the differences between the different antecedent conditions that can contribute to startups being accepted into business incubators in Italy and Romania. The validation of the fsQCA equifinality principle in both samples shows that the selected antecedent conditions, mixed in combinations of “causal recipes”, lead to a high BIAD by business incubators from both countries.
Originality/value
This study reveals the differences between different antecedent conditions, capable to contribute to the start-up acceptance within business incubators from Italy and Romania. Furthermore, the validation of fsQCA equifinality principle in both samples highlight that the selected antecedent conditions, mixed in combinations of causal recipes, lead to a high degree of business ideas' acceptance in business incubators.

Abstract
Purpose
Patient safety remains a top priority in healthcare. Many organizations have developed systems to monitor and prevent harm, and have invested in different approaches to quality improvement. Despite these organizational efforts to better detect adverse events, efficient resolution of safety problems remains a significant challenge. The authors developed and implemented a comprehensive multimodal patient safety improvement program called SafetyLEAP. The term “LEAP” is an acronym that highlights the three facets of the program including: a Leadership and Engagement approach; Audit and feedback; and a Planned improvement intervention. The purpose of this paper is to evaluate the implementation of the SafetyLEAP program in the intensive care units (ICUs) of three large hospitals.
Design/methodology/approach
A comparative case study approach was used to compare and contrast the adherence to each component of the SafetyLEAP program. The study was conducted using a convenience sample of three (n=3) ICUs from two provinces. Two reviewers independently evaluated major adherence metrics of the SafetyLEAP program for their completeness. Analysis was performed for each individual case, and across cases.
Findings
A total of 257 patients were included in the study. Overall, the proportion of the SafetyLEAP tasks completed was 64.47, 100, and 26.32 percent, respectively. ICU nos 1 and 2 were able to identify opportunities for improvement, follow a quality improvement process and demonstrate positive changes in patient safety. The main factors influencing adherence were the engagement of a local champion, competing priorities, and the identification of appropriate resources.
Practical implications
The SafetyLEAP program allowed for the identification of processes that could result in patient harm in the ICUs. However, the success in improving patient safety was dependent on the engagement of the care teams.
Originality/value
The authors developed an evidence-based approach to systematically and prospectively detect, improve, and evaluate actions related to patient safety.

Abstract
Purpose
Material extrusion additive manufacturing processes inevitably produce bead-shaped surface patterns on the walls of parts, which create stress concentrations under load. This study aims to investigate the influence of such stress concentrations on the strength along the build direction (“Z-strength”).
Design/methodology/approach
This work consists of two main parts – an experimental demonstration to show the significance of stress concentrations on the Z-strength, followed by numerical modeling to evaluate the theoretical stress concentration factors (kt) for such shapes. Meso-scale finite element analysis (FEA) was performed to evaluate kt at the roots of the intersecting bead shapes. The critical bead shape parameters influencing kt were identified, and parametric FEA studies were performed on different bead shapes by varying the normalized parameters.
Findings
The experimental results showed that up to a 40% reduction in the effective Z-strength could be attributed only to the presence of surface bead shapes. Bead overhang and root radius were identified as critical shape parameters influencing kt. The results of the parametric FEA studies were used to generate a single empirical equation to determine kt for any bead shape.
Originality/value
Predictive models for Z-strength often focus on crystallization kinetics and polymer chain interdiffusion to predict interlayer adhesion strength. The authors propose that the results of such studies must be combined with surface bead-shape induced stress concentration factors to obtain the combined, “effective” Z-strength.

Abstract
Purpose
This paper aims to study the developed countries’ experience on the cyberbullying legal regulation among adolescents, to identify existing shortcomings in the developing countries’ laws and to develop recommendations for regulatory framework improvement.
Design/methodology/approach
The authors have studied the state regulatory practice of the UK, the USA, Canada, Malaysia, South Africa, Turkey, UAE and analyzed the statistics of 2018 on the cyberbullying manifestation among adolescents in these countries.
Findings
The study results can encourage countries to create separate cyberbullying legislation and periodically review and modify already existing legislation.
Originality/value
The study provides a list of the recommendations to regulate cybercrime in developing countries and prevent it as well. The results may contribute to creating laws related to the regulation of cyberbullying in countries where such legislation does not exist yet or existing regulatory legal acts do not bring the expected results, namely, in Post-Soviet countries and other developing countries of the world.

The purpose of this paper is to measure Mexicans’ perceptions and attitudes about the production and consumption of genetically modified organisms (GMOs).
Abstract
Purpose
The purpose of this paper is to measure Mexicans’ perceptions and attitudes about the production and consumption of genetically modified organisms (GMOs).
Design/methodology/approach
A questionnaire with 63 questions that encompassed 11 latent factors was used to obtain information. The questionnaire was administered to 14,720 people in Mexico’s urban areas.
Findings
The results revealed important similarities and differences with studies in other countries, showing mainly that the respondents did not have sufficient information about GMOs, they have low level of knowledge about GMOs (31.28 percent), are highly distrustful of GMOs, perceive high risk regarding GMOs (59.13 percent), want transgenic products to be labeled (93.59 percent) and do not perceive GMOs’ social values and positive health effects beyond increasing agricultural productivity. Also, it was observed that the higher the educational level of individuals, the lower the acceptance of GMOs.
Research limitations/implications
The authors conclude that it is necessary to generate and provide scientifically accurate information on GMOs, so that people are better informed and can give a critical opinion on the use of GMOs.
Practical implications
The major practical contribution of this research is that it provides empirical knowledge about the perceptions and attitudes toward the production and consumption of GMOs among the Mexican’s urban society, which can be of great help for the Mexican government to rethink if it is an appropriate moment to completely open the doors to international companies to cultivate crops like maize and others that have been postponed due to pressure from the environmental groups, farmers and other sectors of the society.
Social implications
This is especially important in the context of maize as it is part of the cultural heritage of Mexico since ancient times. However, it is not clear what the overall perception is in the Mexican society on the use of GMOs for cultivation.
Originality/value
Southern regions of Mexico are the center of origin of several cultivated plants such as maize and legumes. The introduction of GMOs, called transgenics, in agriculture and food continues to cause enormous controversy in the perceptions and attitudes mainly among environmental groups and farmers in Mexico.

Abstract
Purpose
The purpose of this paper is to review two school intervention projects aiming to promote students' self‐efficacy in Germany. Self‐efficacy, defined as people's “beliefs in their capabilities to organize and execute the courses of action required to produce given attainments”, is a core prevention criterion of mental health. It is positively connected to important facets of personality (e.g. motivational orientation, social competencies) as well as to health‐related situation‐specific behaviour (e.g. coping with stress, conflict solving).
Design/methodology/approach
Two intervention projects, “Self‐efficacious Schools – SESC” and “Fostering Self‐efficacy and Self‐Determination in class – FOSS”, made teachers familiar with the concept of self‐efficacy to enable them to develop and adapt intra‐curricular promotion measures of students' school self‐efficacy and social self‐efficacy.
Findings
Individualisation of task demands and performance feedback as well as a high transparency of teachers' demands and evaluation criteria are beneficial for students' school self‐efficacy. Social self‐efficacy is enhanced by establishing a positive class climate, where students support each other and teachers are sensitive to the individual needs of their students.
Research limitations/implications
Both FOSS and SESC are multi‐component non‐randomised controlled studies. Thus, future research is needed focusing on the different measures separately using RCT‐designs.
Practical implications
The actual implementation of promoting strategies into school lessons is the decisive step of strengthening students' mental health at school. As a consequence, promotion measures have to be embedded into organizational structures which can motivate teachers to learn and implement innovation even under unfavourable conditions.
Originality/value
In contrast to extracurricular activities, there has been limited research on the implementation and evaluation of prevention activities continuously integrated into the mainstream school curriculum and normal lessons.
