Abstract

Purpose

The purpose of this paper is to illustrate how to develop a methodology to set up an initial maintenance program for unmanned aerial vehicles (UAVs) following the well-known Steering Maintenance Group logic method (MSG-3) and taking into account safety concerns based on items probabilities of failure. That is why it is stated that maintenance program is based on reliability principles.

Design/methodology/approach

The proposed methodology follows the MSG-3 framework applied to civil aircraft but where the determination of each probability of failure is achieved applying a morphological analysis. These probabilities are then affected by some factors to calculate the adjusted values to the specific conditions (design, operation and environment) under which the system is expected to operate.

Findings

Main findings are related to the applicability of the morphological analysis on the developing of an initial maintenance program when there is a lack of data that disable the establishment of a coherent maintenance program.

Research limitations/implications

Limitations are related to the absence of a legislative framework consensual in Europe for certification of UAVs and the lack of data concerning UAVs failure modes, causes and their probability of failure.

Practical implications

The developed work and the methodology proposed may be useful for UAVs maintenance program engineers and technicians when developing new systems.

Originality/value

The originality is based on the use of morphological analysis for UAVs to determine the items probabilities of failure when there is a no-data problem. Based on the referred analysis, it is possible to create an initial maintenance program for UAVs.

Abstract

Purpose

Job satisfaction is essential in understanding turnover intentions. Previous studies reveal that highly educated hospitality employees generally have lower levels of job satisfaction, indicating that the antecedents of job satisfaction may be different from hospitality managers and frontline employees. This study compared the different antecedents of job satisfaction for housekeeping managers and employees.

Design/methodology/approach

This study used a mixed-methods approach for a two-part study. The researchers recruited housekeeping managers for the exploratory survey. The results of open-end questions helped us build a custom dictionary for the text mining of comments from Glassdoor.com. Finally, a multilinear regression of themes from housekeeping employees’ ratings on Glassdoor.com was conducted to understand the antecedents of job satisfaction for housekeeping managers and employees.

Findings

The results of the exploratory survey indicated that the housekeeping department has an urgent need for organizational support and training. The text-mining revealed organizational support impacts both managers and frontline employees, while training impacts managers more than employees. Finally, the regression analysis showed compensation, business outlook, senior management, and career opportunity impacted both groups. However, work-life balance only influenced managers.

Originality/value

With a large number of employees at low salaries, housekeeping departments have a higher-than-average turnover rate for lodging. This study is among the first to compare the antecedents of managers’ and frontline employees’ job satisfaction in the housekeeping department, extending Social Exchange Theory. It provides suggestions for the housekeeping department to decrease turnover intentions.

Abstract

Purpose

Building upon Social Exchange Theory, this study explores the relationship between perceived opportunities for competency development (POCD), subjective career success (SCS), and organizational citizenship behaviors (OCBs). Given the importance of SCS in providing mutual benefits for both the employee and the organization, this study examines how SCS plays a mediating role in the relationship between POCD and OCBs.

Design/methodology/approach

Data was collected from 353 full-time working professionals in Malaysian organizations through a two-wave hardcopy questionnaire survey. The data was then analyzed using structural equation modeling and the bootstrapping method.

Findings

The study found no significant direct relationship between POCD and OCBs. However, the bootstrapping analysis uncovered that SCS mediated this relationship, indicating a significant full mediation effect.

Research limitations/implications

To increase the external validity of findings, future studies should include samples from various industries in both the public and private sectors.

Originality/value

In contrast to the findings from previous studies, this study adds value to the career literature by demonstrating that without a sense of SCS, even with competency development opportunities, employees are less likely to engage in OCBs. It highlights the importance of SCS in fostering mutual benefits for both the employee and the organization.

Abstract

Purpose

This paper aims to examine the relationship between perceived investments in employees’ development (PIED) on work engagement and the moderating effects of psychological capital on this relationship for liquid knowledge workers, employed in the Indian cutting and polishing of diamond industry (CPD).

Design/methodology/approach

A questionnaire composed of established scales was administered to 134 liquid knowledge workers. Having established convergent and discriminant validity using structural equation modelling, the model was further analysed using the Process macro to check for direct and moderating effects.

Findings

The research findings suggest that the perceived investment in employee development and psychological contract enhancement (relational and transactional) made by CPD units for liquid knowledge workers positively influenced their work engagement level. The study also finds that relational contract (not transactional contract) positively moderates the relationship between perceived investment in employee development and work engagement.

Research limitations/implications

This is a cross-sectional single source study; future studies could look at longitudinal and multisource perspective.

Practical implications

The study presents a “star matrix of engagement” that guides the application of the two strategies of perceived employee development and psychological contract enhancement for liquid knowledge workers. This has implications for design and implementation of human resource management practices and policies for employee management.

Originality/value

The study makes significant contributions to existing literature on antecedents of work engagement of liquid knowledge workers by examining the direct and moderating influences.

Abstract

Purpose

A major trend in the changing nature of work is the increasing use of temporary workers. Although common among students, older employees have joined the ranks of temporary workers as they extend their work lives. Temporary workers tend to report lower affective commitment and consequently poorer work outcomes. However, different generations of workers may conceive temporary work differently from each other. The purpose of this paper is to explore how different generations of temporary workers, respond to human resource practices (HRP), which in turn influences their affective commitment and work performance.

Design/methodology/approach

The sample is comprised of 3,876 temporary agency workers (TAWs) from seven temporary employment agencies in Portugal. The authors undertook multiple group SEM analyses to test a moderated mediation model that accounts for TAWs’ affective commitment (toward the agency and the client company) across three generations (Baby Boomers, Generation X and Millennials) in the relationship between human resources practices and overall perceived performance.

Findings

After controlling for gender, age and tenure, the authors find generational differences in the perceptions of HRP and perceived performance. The results support the moderator effect of generations in the direct and indirect relationships – through both affective commitments – between TAWs’ perceived HRP and perceived performance.

Research limitations/implications

The cross-sectional design limits the possibility to make causal inferences.

Originality/value

This study contributes to a better understanding of how different generations respond to temporary employment relationships. The findings suggest important differences in the way in which the same HRP system relates (directly and indirectly thorough affective commitment toward the client) with their perceived performance across different generations.

Abstract

Purpose

This paper aim to propose a methodological mapping approach for the evaluation of dissertations and theses of graduate programs in the area of environmental sciences in Brazil in relation to the UN sustainable development goals (SDGs).

Design/methodology/approach

The research is characterized as exploratory with qualitative/quantitative approach. The proposed model was developed as a computational algorithm with a pilot being adopted as a professional master in national network for teaching in environmental sciences (ProfCiAmb) comprising associated courses from nine Brazilian public universities. 230 dissertations completed between 2018 and 2020 were analyzed.

Findings

A total of 266 correlations were identified between the texts and descriptors of each SDG. Correlation values between 0.100 (minimum value – Vmin) and 0.464 (maximum value – Vmax) were observed. SDG 4 – Quality Education (Vmax = 0.399) and SDG 6 – Drinking Water and Sanitation (Vmax = 0.464) were those with the highest correlation values, followed by SDG 3 – Health and Well-Being (Vmax = 0.299) and SDG 17 – Partnerships and Means of Implementation (Vmax = 0.249).

Practical implications

The construction of the computational algorithm provided consistent quantitative analyses with potential to contribute to the improvement of the multidimensional evaluation of graduate studies, as well as to support public policies related to teaching and research and strategic planning of the programs.

Originality/value

The relevance of this study lies in the creation of a model that involves the creation of metrics and tools regarding the impact of graduate studies on society.

Abstract

Purpose

This research focused on agency work. Previous studies highlighted the importance of motivations to understand workers’ attitudes, behaviors and well-being. Thus, the purpose of this paper is to analyze the contribution of perceptions of support from organizations to autonomous motivation for temporary agency employment, the relationship of motivations with workers’ well-being and the mediating role of motivations between perceptions of organizational support (POS) and workers’ well-being.

Design/methodology/approach

The hypotheses were tested with a sample of 3,983 temporary agency workers and using structural equation modeling.

Findings

The authors verified that POS from the agency contributed to both autonomous motivation and controlled motivation for temporary agency employment, whereas POS from the client company only contributed to autonomous motivation for temporary agency employment. Moreover, autonomous motivation for temporary agency employment was positively associated with workers’ well-being. Contrary to expectations, controlled motivation for temporary agency employment was not significantly associated with workers’ well-being. As predicted, autonomous motivation for temporary agency employment was a mediator in the relationship between POS and workers’ well-being.

Research limitations/implications

The study relies on self-reported data, and it does not have a longitudinal design.

Practical implications

An important implication of this research study is that organizations, through the support provided to the workers, may contribute positively to increase workers’ autonomous motivation for temporary agency employment, and, in turn, more autonomous motivation for temporary agency employment relates to higher levels of workers’ well-being.

Originality/value

The study innovates by including in the same model variables that may contribute to workers’ motivation for temporary agency employment as well as the outcomes that may arise from workers’ motivation for temporary agency employment.

Abstract

Purpose

The purpose of this research is to establish a conceptual model to understand the impact of Total Productive Maintenance (TPM) and Industry 4.0 (I4.0) on the transition of a Circular Economy (CE). Also, the paper explores the combined impact of TPM, I4.0 and CE on the sustainability performance (SP) of manufacturing firms.

Design/methodology/approach

The conceptual model is proposed using the dynamic capability view (DCV) and empirically validated by partial least squares-structural equation modelling (PLS-SEM) using 304 responses from Indian manufacturing firms.

Findings

The results suggest that I4.0 positively impacts TPM, CE and SP, also showing TPM's positive impact on CE and SP. In addition, CE has a positive influence on the SP of manufacturing firms. Furthermore, CE partially mediates the relationship between I4.0 and SP with TPM and SP. The study also identifies TPM, I4.0 and CE as a new bundle of dynamic capabilities to deliver SP in manufacturing firms.

Originality/value

The present research adds to the knowledge and literature on DCV by identifying the importance of CE in the settings of I4.0 and TPM, especially in the context of sustainability. Also, the current study offers a new set of dynamic capabilities and provides some significant future recommendations for researchers and practitioners.

Abstract

Purpose

Disasters continue to be most prevalent and severe for marginalised communities. To reach those furthest behind first, as the global community pledges in the 2030 Agenda, a critical assessment of equity in disaster risk governance is necessary. Yet, the understanding of factors that mediate the capacity of the governance processes to achieve equity ambitions is limited. This paper addresses this gap by proposing and testing a conceptual framework to assess equity in disaster risk governance.

Design/methodology/approach

The framework analyses the extent to which institutional relationships and data in risk governance support inclusion and diversity of voice and enable the equitable engagement of communities. The study applied the framework to key risk policies across governance levels in Brazil and Colombia.

Findings

The study finds that institutional awareness of cross-sectoral and -scalar coordination clearly exists. Yet, the engagement of actors further down the governance scale is framed reactively at all scales in both countries. The analysis of the risk data practices indicates that although data integration and sharing are key policy priorities, the policies frame the relations of disaster risk data actors as hierarchical, with data needs determined from the top down.

Originality/value

A key contribution of this framework is that its equity view results in a nuanced analysis, thus pointing to the differences between the two countries concerning the factors that mediate these challenges and providing specific entry points for strengthening equity in risk governance policies.
