The purpose of this paper is to analyse and compare the impact of implementation of ISO 9001:2008 Standards perceived by Management Teams and Teachers in schools in four autonomous communities in Spain.

To assess this impact, the authors used an evaluation instrument made up of 93 items assessing seven major dimensions, whose reliability has been excellent for the full scale (Cronbach’s α = 0.987) and dimensions (α > 0.93). The authors conducted descriptive and differential analyses (ANOVA and t-test for independent samples) of the assessments by professional position (managers and teachers) and other variables (size and type of school, years of implantation, etc.). A factorial analysis of variance was conducted to analyse the interaction effect between these variables in each of the evaluated dimensions.

The most significant results show a high impact on the dimension management, medium on communication, learning process and external relations and low impact on climate, support and recognition and satisfaction. Likewise, the authors found that members of the Management Teams valued the impact that ISO 9001:2008 Standards have had on all dimensions at a higher level, except for external relations, where no significant differences between Teachers and Management Team members were found.

The study makes it possible to conclude that in general terms, the members of the Management Team of the schools perceive a higher impact of the implementation of ISO 9001:2008 Standards than teacher do in the different dimensions evaluated.

The specialised literature shows the lack of studies related to the impact that the implementation of quality management systems has on organisations. Specifically, this study provides conclusions to the scientific and professional community with objective evidence of the impact ISO 9001:2008 implementation has had on schools, through an indirect system of perceptions of the education community of the changes, which according to them had taken place as a result of implementation. Thus, this study contributes to the development of a new body of knowledge by evaluating this impact.

This article aims to present the differences in implementation between individual mentoring programs (IMPs) and group mentoring programs (GMPs).

This exploratory study used semi-structured interviews with 16 experts: mentoring program (MP) coordinators, consultants and mentors. During the interviews, the steps in implementing a mentoring program were reviewed and discussed by practitioners.

Based on the interviews and contrasting with the proposed implementation model, the authors compared IMPs and GMPs. The results highlight the role of the GMP coordinators, especially in the selection of mentors, mentees and generating resources that favor the beneficial effects of group dynamics on mentoring processes.

This model for implementing MPs and the differences identified between IMPs and GMPs provide practical help to program coordinators (PCs) and mentors to deploy MPs by highlighting the relevant aspects.

Mentoring is a Human Resource Development (HRD) technique whose implementation at the program level needs further deepening for practitioners. This is the first work that emphasizes the differences to be considered in the design and implementation of MPs by taking the individual or group dimension of mentoring.

The purpose of this article is to investigate the return associated with a Canadian dollar (C$) investment in the USA under passive, random walk, value at risk, and Sharpe ratio strategies.

To comply with the purpose, this paper used a GARCH model, and used, as basic data, daily C$ exchange rates and weekly US and Canadian interest rates on 90‐day CDs, from January 2 to November 26, 2004.

The empirical results suggest that currency returns are positively correlated to risk; and that the return provided by the random walk strategy beats the other strategies considered in this paper.

The findings suggest that currency investment is similar to other forms of investment, since it shows a positive relationship between risk and return. It also supports the long‐standing belief that sophisticated strategies do not beat simple‐minded approaches such as a random walk strategy.

This paper uses a utility function to investigate the response of investors to risk and return under different aversion scenarios.

Crisis can bring out the true nature of people. Also in terms of consumers, this can be for better or for worse. On the one hand, irresponsible consumer behaviours rose, with for example people starting to hoard bulk quantities of toilet paper, rice and flour, which in turn increased scarcity perceptions and induced fear in others. Besides panic buying, impulse purchasing also rose, as a means to alleviate negative feelings and to treat oneself (particularly once the stores reopened again). For some consumers, this increased buying can become compulsive, leading to shopping addiction and financial problems. On the other hand, the crisis also forced a pause in the rat race we live, allowing people to reconsider their consumption behaviour and evolve towards more sustainable choices. This chapter provides insights on both directions, allowing retail managers to incorporate this new reality in further strategic decisions. In what follows, three consecutive stages in notable changes in consumer behaviour in the pandemic crisis are discussed: from reacting (e.g. hoarding), over coping (e.g. do-it-yourself behaviours), to longer-term adapting (e.g. potentially transformative changes in consumption).

The purpose of this study is to provide a bibliometric analysis of global research publications on virtual and augmented reality (VR/AR) technologies in the understanding, diagnosis and treatment of mental disorders.

The SciVerse Scopus database was used to retrieve relevant documents using a validated search strategy for the study period from 1980 to 2021.

In total, 1,233 research articles were found. Research in this field has experienced steep growth since 2017; was disseminated by journals in the fields of clinical psychology, neuroscience, psychiatry and computer sciences; was mainly carried out by scholars in high-income countries with advanced digital technology; has a relatively high number of authors per article but with a relatively poor cross-country research collaboration; was led by researchers and institutions mainly from the USA, Spain and Italy; and has received the highest number of citations for articles on anxiety and phobias.

Bibliometric methodology is a useful tool for identifying evolution growth patterns and research hot topics in the use of emerging technologies in clinical practice. Research on implementing AR/VR technologies in medicine will be enhanced by strengthening international research collaboration. More research attention should be paid to new emerging technologies in the mental health field.

The use of VR/AR technologies became popular as an alternative to or adjunct to traditional therapy in mental health practice. The rapid increase in research publications in recent years suggested that AR and VR technologies were both acceptable and simple to use. A wide range of mental health disorders could be managed by AR/VR technologies. Training medical and nursing students on various new technologies is important to cope with the digital revolution.

Based on the volume and growth patterns of research publications, there is a promising future for the use of VR/AR technologies in the field of mental health. Teaching and training health-care professionals on the proper use of VR/AR are needed to support their potential future use.

The aim of this paper is to introduce a hexapod walking robot specifically designed for applications in humanitarian demining, intended to operate autonomously for several hours. To this end, the paper presents an experimental study for the evaluation of its energy efficiency.

First, the interest of using a walking robot for detection and localization of anti-personnel landmines is described, followed by the description of the mechanical system and the control architecture of the hexapod robot. Second, the energy efficiency of the hexapod robot is assessed to demonstrate its autonomy for performing humanitarian demining tasks. To achieve this, the power consumed by the robot is measured and logged, with a number of different payloads placed on-board (always including the scanning manipulator arm assembled on the robot front end), during the execution of a discontinuous gait on flat terrain.

The hexapod walking robot has demonstrated low energy consumption when it is carrying out several locomotion cycles with different loads on it, which is fundamental to have a desired autonomy. It should be considered that the robot has a mass of about 250 kg and that it has been loaded with additional masses of up to 170 kg during the experiments, with a consumption of mean power of 72 W, approximately.

This work provides insight on the use of a walking robot for humanitarian demining tasks, which has high stability and an autonomy of about 3 hours for a robot with high mass and high payload. In addition, the robot can be supervised and controlled remotely, which is an added value when it is working in the field.

This study aims to construct two environmental disclosure indices (EDI), one obtained from the mandatory reporting (annual report) and the other from the voluntary reporting (sustainability report), to compare their evolution. In addition, the authors developed and evaluated a conceptual model that aims to analyse if the two EDI are affected by industry, environmental certification, lucratively and corporate governance attributes. The legitimacy, signalling and voluntary disclosure theories are used to support the theoretical relationship between the company’s characteristics, corporate governance and environmental disclosure.

Using the content analysis technique, the authors have developed two indices to assess the level of environmental disclosure in the companies’ mandatory and voluntary reporting. In addition, to analyse the determinants of EDI, the authors applied the technique of multiple linear regression using panel data.

Based on Portuguese listed companies (Euronext-Lisbon), the results, from 2015 to 2017, exhibited an increase of 14.6% and 25.8% for the EDI obtained from the annual reports and for EDI obtained from the sustainability reporting, respectively. In addition, the results revealed that the environmental certification, lucratively, number of members on board and number and proportion of women of the board directors tend to affect the annual reporting EDI. Regarding the sustainability reporting EDI, the results showed that the environmental certification, lucratively and proportion of independent members of the board of directors have an impact on it.

The study focuses on quantitative rather than qualitative disclosures and it brings some insights to the theoretical field.

The results obtained can assist corporate decision-making processes regarding the improvement of environmental disclosure, both on the mandatory annual report and on voluntary sustainability reports.

This study brings new perspectives to this topical issue in accounting. Originally, this study is applied to Portuguese listed companies and it shows different trends and determinants of environmental disclosure when included in the annual reporting or sustainability reporting.

This paper aims to identify, assess and classify the most significant mentee outcomes of formal mentoring processes aimed at managerial development.

After conducting an extensive literature review to identify the most significant mentee outcomes in the management field, a survey was conducted with a sample of 80 experienced mentees. An exploratory factor analysis (EFA) has been performed to simplify and contribute to operationalizing these results. Finally, focus group and nominal group techniques were conducted with practitioners to better understand the findings.

A total of 27 mentee outcomes have been identified in the literature. EFA analysis has allowed us to downsize the 27 outcomes into four factors encompassing the most relevant mentee outcomes. The authors then provide an interpretation and discussion of the results.

This work compiles, reviews and systematizes existing studies on mentee outcomes in the field of management, classifying the results in a novel manner.

In response to the challenges posed by the social environment, numerous individuals with autism use coping strategies, engaging in a phenomenon known as “camouflaging” to mask their distinctive traits. Despite the growing attention directed toward this area of study, to date, there are no bibliometric studies delineating the evolution of this research theme. This study aims to analyze scientific research on camouflage and the autistic spectrum published in Web of Science (WoS).

Articles on camouflage and autism were retrieved from the WoS. The advanced search interface used was “Title, Abstract, Keywords (autistic OR asperger syndrome OR Autism OR ASD AND camouflage OR camouflaging AND Masking).” The analysis and visualization of the selected records and their data were carried out using MS Excel (v16.0) and Biblioshiny (v2.0, R package).

Following the selection process, a total of 70 articles were included. Notably, the UK emerged as the leading contributor in terms of the number of published articles. Prominent authors in this domain included William Mandy, Laura Hull and Meng-Chuan Lai, who exhibited the highest number of published articles and citations. The Journal of Autism and Developmental Disorders stood out as the most prolific journal. Predominant research themes encompassed camouflage (and its synonyms, masking or compensation), gender differences and mental health.

This study contributes to existing knowledge on this topic, as well as identifying new areas of research related to autism and camouflage. Moreover, it serves as a valuable resource for health-care professionals, including physicians and clinical psychologists, who may seek to augment their understanding and proficiency in the field.

This study aims to investigate the effects of ball–material ratio on the properties of mixed powders and Cu-Bi self-lubricating alloy materials.

Cu-Bi mixed powder was ball milled at different ball–material ratios, and the preparation of Cu-Bi alloy materials was achieved through powder metallurgy technology. Scanning electron microscopy, X-ray diffraction and Raman spectroscopy were conducted to study the microstructure and phase composition of the mixed powder. The apparent density and flow characteristics of mixed powders were investigated using a Hall flowmeter. Tests on the crushing strength, impact toughness and tribological properties of self-lubricating alloy materials were conducted using a universal electronic testing machine, 300 J pendulum impact testing machine and M200 ring-block tribometer, respectively.

With the increase in ball–material ratio, the spherical copper matrix particles in the mixed powder became lamellar, the mechanical properties of the material gradually reduced, the friction coefficient of the material first decreased and then stabilized and the wear rate decreased initially and then increased. The increase in the ball–material ratio resulted in the fine network distribution of the Bi phase in the copper alloy matrix, which benefitted its enrichment on the worn surface for the formation a lubricating film and improvement of the material’s tribological performance. However, a large ball–material ratio can excessively weaken the mechanical properties of the material and reduce its wear resistance.

The effects of ball–material ratio on Cu-Bi mixed powder and material properties were clarified. This work provides a reference for the mechanical alloying process and its engineering applications.
