Abstract

Purpose

Remand prisoners (RPs) are known to be in a more vulnerable situation than those already convicted. Beyond the difficulties to adapt to the prison, RP also tend to experience tough circumstances due to the uncertainty of their future. This study aims to further test the psychometric properties of the Suicide Concerns for Offenders in the Prison Environment (SCOPE-2) in a sample of RP.

Design/methodology/approach

The authors have carried out a confirmatory factor analysis to test the psychometric qualities of the SCOPE-2. The authors tested the originally proposed two-factor structure composed of two subscales: optimism and protective self-worth. Also, the authors examined internal consistency through Cronbach’s alphas. Convergent validity was tested by correlational analyses between SCOPE-2 subscales and the Suicide Behaviors Questionnaire-Revised and Brief Symptom Inventory (BSI) total scores. Finally, the authors have tested known-groups validity by carrying out discriminant analysis by testing the SCOPE-2 subscales’ ability to predict belonging to a group with previous suicide attempts.

Findings

The confirmatory factor analysis showed an acceptable model fit, even though the subscale “Protective self-worth” presented a less acceptable fit. The correlation analysis supported the convergent validity of the SCOPE-2. Both the “Optimism” and “Protective self-worth” subscales showed a positive correlation with the total scores of BSI. Finally, the Portuguese version of SCOPE-2 also showed known groups validity. Concretely, the “Optimism” scores revealed an acceptable predictive accuracy.

Practical implications

This study embraces important contributions to the practice as it was the first study to validate a measure to assess vulnerability for suicide and self-harm in male and female RP.

Originality/value

To the best of the authors’ knowledge, this was the first study to validate an instrument to assess vulnerability for suicide and self-harm in both male and female pretrial detainees. Knowing their particular case, as well as the lack of responses for these individuals, it is particularly important to access suicide concerns that could precede suicide attempts.

Abstract

Purpose

The objectives of the proposed model are: aiding nursing staff in documentation tasks, which can be onerous and stressful; and helping management by offering an estimate of the nursing workload, which can be considered for administrative purposes, such as staff scheduling.

Design/methodology/approach

An exploratory-descriptive study was conducted in order to identify, investigate, and describe the problem of documenting nursing activities and workload estimation in an intensive care unit. Technological solutions were explored, and models were proposed to address these issues.

Findings

Cross-dataset experiments were performed, and the model was able to offer an adequate estimate of the nursing workload. The results suggest that continuous retraining is essential for maintaining high accuracy. While the proposed model was considered in the context of an adult ICU, it can be adapted to other contexts, such as elderly care.

Research limitations/implications

While the proposed solution seems promising, further research is required, such as deploying this system in an ICU and facing challenges in the areas of computer security, medical ethics, and patient data privacy. More patients’ variables could also be collected to improve the workload estimates.

Originality/value

Nursing workload assessment is critical to improve the cost-benefit ratio in health care, offer high-quality patient care, and reduce unnecessary expenses, and this process is usually manual. An automated device can automatically document the amount of time spent in patient care activities in a more transparent, efficient, and accurate manner, freeing staff for more urgent activities and keeping management better informed about day-to-day nursing operations.

Abstract

Purpose

The purpose of this paper is to evaluate the impact of different Additive Manufacturing (AM) orientations on the structural behavior of topologically optimized wings for Unmanned Aerial Systems (UAS), which might enable lightweight and low cost, yet complex, wing structural designs.

Design/methodology/approach

Based on an aerodynamic load, a two dimensional NACA0012 airfoil is topologically optimized considering PolyLatic Acid (PLA), several volume fractions and different manufacturing orientations. Then, the resulting topologies are post-processed to allow for manufacturing and extrude to three dimensional wing geometries with constant cross-sections. These wings are then manufactured using Fusion Deposition Modeling (FDM) technology and their dynamic structural behavior analyzed by means of Experimental Modal Analysis (EMA) in the linear elastic region.

Findings

Volume fraction increase is observed to improve the structural performance without increasing the manufacturing time. Despite manufacturing the wing from the leading edge to the trailing edge can reduce manufacturing time using FDM technology, it is found to be more difficult to build.

Originality/value

This research is a contribution toward the design and built of lightweight and low cost wings for UAS.

Abstract

Purpose

This paper aims to exemplify the use of project management tools in the scheduling of aircraft maintenance activities. This process is known as maintenance, repair and overhaul and it has gained importance within the aeronautical sector due to its expected growth in the coming years; however, it also faces increasing competitiveness in its market. This fact gives rise to the need of acting in maintenance management and seeking lower costs while maintaining the quality of the service provided. The purpose of this paper is to propose the structuring of a procedure that aims to reduce the total maintenance time (downtime) and guarantee the delivery of the aircraft on time.

Design/methodology/approach

The paper, through a case study at a Brazilian aircraft maintenance center, used critical path method and critical chain project management, the latter being derived from the theory of constraints, with the purpose of analyzing resources systematically and synchronizing the activities in the precedence network.

Findings

As a result, it is shown that downtime can be reduced from 11 to 5 days and improvements are proposed to achieve greater market competitiveness.

Originality/value

This paper demonstrates the competitive advantage that resulted from the application of project management tools in the aircraft maintenance planning and execution.

Abstract

One of the two main tasks of innovation leadership, a practice to inspire and enable creativity and innovation in organisations, is to construct a creativity-enabling organisational environment. One form of this main task is using developmental interactions, like mentoring, as innovation leadership practices. A hackathon is one type of innovation contest with three designed phases: pre-hackathon, hackathon event and post-hackathon, involving multiple stakeholders with distinct roles, such as hackers and mentors. In a hackathon, the central activity of mentors is to support the hackers’ innovation process, especially in idea creation and concept development. The mentor role has not been focal in hackathon studies; thus, this chapter addresses the role, impact, and ways to acknowledge the mentors as an integral, contributing innovation leadership practice in hackathons. As an empirical study, this chapter presents the results of a public sector case in a Swedish multi-disciplinary municipality conducting intra-organisational hackathons in three different collocations. The chapter contributes to the literature on innovation leadership at the team level with mentorship in innovation contests in the public sector context by revealing the dual-role tension of innovation leadership in mentor activities in the hackathon event phase from both the hackers’ and mentors’ viewpoints, and the necessity of mentor-benefitting training in pre-hackathon phase.

Abstract

Creative labor in the perfume industry can be identified as perfumers or perfume designers who have spent years in the industry either with formal education or firsthand practice and have developed their skills. They are skilled in matching various fragrances and work with the client's framework to produce perfumes. This chapter analyzes the literature about creative labor's living conditions and aspirations, focusing on the perfume industry and its role in producing perfumes. Perfumery is looked at from a creative and artistic perspective, and the prerequisites of becoming a successful perfumer are analyzed. In an industry where talent plays a crucial role in one's success, perfumers are identified as those who work with large brands to produce perfumes for the masses or cater to specific individuals. Bespoke perfumers such as Sylvaine Delacourte and Jean-Claude Ellena have a lot more flexibility and autonomy in their work because of their superior level of skill. They can charge soaring prices for their work. Whereas other creative workers in creative projects have to undergo a long collaborative process where they are required to work within the framework provided by their clientele to launch a new perfume product. Previous literature by Richard Florida and Brian Moeran about the creative class has been used to identify the characteristics of creative labor in the perfume industry. The creative process in perfumery in terms of high-end luxury products and mass production products is discussed. Manufacturing of perfumes today is primarily industrial, and the role of perfumers in the high-end prestige market and mass market in terms of their creativity is analyzed. Additionally, the top perfumers’ style of work and the creative process involved in making perfumes are discussed.

Abstract

Purpose

Logistics service providers (LSPs) have unique resources and capabilities that position them to deliver supply chain finance (SCF) solutions. The study aims to discuss and illustrate the necessary resources and process of value creation and capture of LSPs, potentially offering SCF solutions.

Design/methodology/approach

Relying on a theoretical framework, combining a resource-based view (RBV) with the literature on SCF, the authors apply an abductive case study methodology, including 11 interviews with representatives from four LSPs.

Findings

The main findings are as follow: (1) although an LSP has sufficient resources for value-added SCF solutions, it may not capture enough value to motivate realising them; (2) an LSP considering offering SCF should account for the interaction between its resources and cargo transit times, risk and regulatory restrictions and (3) future studies should distinguish between financing the logistics services and the moved products.

Research limitations/implications

The authors contribute to the growing field of SCF research by analysing motives and barriers for LSPs to offer SCF service to their customers. Because none of our case companies decided to move beyond experimentation further research is needed on the resources and capabilities needed for LSPs to successfully venture into SCF.

Practical implications

The study provides LSPs with clear indications of the difficulties involved when contemplating a move into SCF solutions and discusses the potential value of offering such services.

Originality/value

Despite evidence of LSPs engaging in SCF in various industries, academic contributions do not go beyond operational conditions or quantification of benefits. The authors add evidence on how LSPs are currently evaluating the prominence of adding SCF to their value offerings, including a new perspective on resources, value generation and capture mechanisms.

Abstract

Purpose

The purpose of this paper is to present a prospective study of sustainable mobility in the framework of a supporting energy management systems (EMS). Technological advances are still required, namely electric vehicles (EV) endowed with improved EMS in order to increase their performance by making the most of available energy storage technologies. As EVs may be seen as a special domestic load, EMS are proposed based on demand-sensitive pricing strategies such as the Energy Box discussed in this paper.

Design/methodology/approach

The study presents an overview of electric mobility and an urban EV project, with special focus on the utilization of its energy sources and their relation with the energy demand of a typical urban driving cycle. Results based on the ECE 15 standard driving cycle for different free market electricity tariffs are presented.

Findings

The analysis based on present Portuguese power and energy tariffs reveals that it is highly questionable whether the resulting profit will be enough to justify the potential inconveniences to the vehicle user, as well as those resulting from the increased use of batteries.

Practical implications

The conclusions indicate that more studies on the trade-offs between grid to vehicle and vehicle to grid schemes and electricity pricing mechanisms are needed in order to understand how the utilization of EVs can become more attractive in the end-users’ and utilities’ perspectives.

Originality/value

The paper proposes an approach for future electricity tariff behavior that could be applied to EVs in order to understand whether or not their grid integration in charge and discharge situations would be beneficial for end-users and utilities, in the framework of smart energy management technologies.

Abstract

Purpose

This study aims to explore the role of socially responsible human resource management (SRHRM) as a key driver of employee voice behaviour. The hypotheses included that these human resources management (HRM) practices strengthen employees’ motivation to voice their opinions by increasing their work engagement (WE), thereby encouraging them to share their ideas and concerns about their organization more actively. The hypotheses also proposed that this effect is especially pronounced when employees experience a heightened sense of psychological safety.

Design/methodology/approach

A survey-based correlational study was conducted with a sample of 289 participants to analyse the proposed relationships between the selected variables.

Findings

The results indicate that SRHRM and WE are significantly associated with both promotive and prohibitive voice behaviour among employees. In addition, the moderated mediation model revealed that employees who perceive their organization as adopting SRHRM practices display higher levels of WE, which in turn increases these individuals’ likelihood of engaging in both types of voice behaviour. This relationship is particularly strong for promotive voice when employees experience high levels of organizational psychological safety.

Research limitations/implications

The findings are limited by the cross-sectional research design, which restricts causal inference.

Practical implications

By adopting people-centred HRM practices, organizations can foster psychologically safe environments that enhance employees’ willingness to engage in behaviour beneficial to their organization, such as WE and voice behaviours.

Originality/value

The results highlight the critical role of SRHRM and offer evidence-based insights into how interventions can foster positive employee behaviours and attitudes, including WE and voice behaviour.
