Abstract

Purpose

Integrated vehicle health management has been developed for several years in different industries, to be able to provide the required inputs to determine the optimal maintenance operations depending on the actual health status of the system. The purpose of this paper is to demonstrate the potential of a physics-based model (PbM) for prognostics with a real case study, based on the detection of incipient faults and estimate the remaining useful life of a planetary transmission of an aircraft system.

Design/methodology/approach

Most of the research in the area of health assessment algorithms has been focused on data-driven approaches that are not based on the knowledge of the physics of the system, while PbM approaches rely on the understanding of the system and the degradation mechanisms. A physics-based modelling approach to represent metal-metal contact and fatigue in the gears of the planetary transmission of an aircraft system is applied.

Findings

Both the failure mode caused by metal-metal contact as caused by fatigue in the gears is described. Furthermore, the real-time application that retrieves the results from the simulations to assess the health of the system is described. Finally the decision making that can be executed during flight in the aircraft is incorporated.

Originality/value

The paper proposes an innovative prognostics health management system that assesses two important failure modes of the planetary transmission that regulates the speed of the generators of an aircraft. The results from the models have been integrated in an application that emulates a real system in the aircraft and computes the remaining useful life in real time.

Abstract

Organizing new service development is an important topic for decision makers in service firms, since continuous innovation is expected to pay off. Although the literature on organizing new service development has grown rapidly over the last decade, the numerous publications are highly fragmented, each concentrating on a small piece of the complex innovation puzzle. This paper classifies current literature on organizing new service development (NSD) into two evolutionary stages: managing key activities in the NSD process, and creating a climate for continuous innovation. For both stages its consequences for the initiation and implementation of new services are discussed. The paper ends with limitations and suggestions for future research.

This article aims to explore whether and how economic, political and demographic municipal conditions shape citizens' attitudes regarding decentralised social policies.

Abstract

Purpose

This article aims to explore whether and how economic, political and demographic municipal conditions shape citizens' attitudes regarding decentralised social policies.

Design/methodology/approach

The authors analysed the 2018 wave of the Dutch Local Election Studies, which includes a novel survey item asking respondents whether they prefer local social policies to be primarily: (1) protection-based, (2) cohesion-building or (3) activation-based. The authors appended context indicators to that survey and performed multilevel logistic regression analyses (1,913 respondents nested in 336 municipalities).

Findings

At the individual level, these preferences are affected by gender, age, income, education and political inclination, as expected. However, preferences towards local social policies are not shaped by local economic, demographic or political conditions. The authors discuss the implications of these findings for future research.

Originality/value

By using unique data, including a newly developed survey item, this study is the first to explore whether and how municipal conditions shape preferences regarding local welfare. Understanding those preferences is increasingly important as many Western European countries have decentralised swathes of social policies from the national to the local level in recent decades.

Abstract

In this chapter, we analyze the interactions between local governments and citizens’ initiatives. In the Netherlands, local governments take up the role of civic enabler based on a modest approach that leaves citizens room to invent and design initiatives on what they deem to be public issues by facilitating and activating their efforts. We focus on how a proactive form of this approach toward citizens’ initiatives in deprived neighborhoods affects citizen–government relations. Our research is based on a case study in the city of Amsterdam. We find that particularly more women and migrants took up a wide variety of initiatives, which suggests that the neighborhood approach is more inclusive than deliberative approaches. We also find that initiators developed a positive attitude toward public institutions that enable them and that they started to see frontline workers as collaborators in their initiatives with whom they could have personal and authentic interactions, as opposed to the cool bureaucratic response from government officials that they were used to. To close the chapter, we discuss some risks of the proactive enabling approach, we compare our findings to problems that citizens’ initiatives often face during their interactions with local institutional actors in the Netherlands found in other literature, and we briefly discuss possible implications of practicing a modest enabling approach for developments in governance.

Abstract

Purpose

Performance-based contracting (PBC) plays an increasingly important role in the defense industry. This paper aims to investigate factors that influence service provider’s willingness to accept PBC-induced risks. It also shows how these risks could be managed in a military service supply chain.

Design/methodology/approach

The case study focused on the relationship between a service provider and a customer that acted on behalf of other users in the defense sector. The contract involved the sustainment of a military engine in a complex supply chain.

Findings

The service provider’s performance attributability appeared to have a strong impact on its willingness to take PBC-induced risks. For the parts where the service provider did not have full control over the service performance, exclusions and Service Level Agreements (SLAs) were used to manage and mitigate the risks associated with uncontrolled performance. The service provider’s willingness to accept PBC-induced risks was also affected by its ability to make accurate forecasts, the applied growth path and the length of the contract.

Research limitations/implications

This case has specific characteristics, unique by time (maturity of the technical system and supply chain) and place (market). It is recommended that results are tested in other research settings.

Practical implications

Organizations should be aware of the factors that influence a service provider’s willingness to bear PBC-induced risks. Customers should limit PBC to those parts of a contract where risks are of an acceptable level. Also, it is recommended to follow a phased growth path when it is not possible to make accurate forecasts in a PBC context.

Originality/value

This study is the first to address critical issues concerning the identification and management of risks under PBC in the defense industry.

Abstract

Purpose

Scholars have emphasized the antecedent role of personal factors such as creative self-efficacy (CSE) in enhancing innovative behavior in work settings. Existent studies have revealed that individuals with high CSE have the cognitive ability to resiliently exhibit innovative work behavior (IWB). Little is however known as regards the influence of CSE on innovative work behavior in service settings, more so in developing countries. This study sought to establish the antecedent role of CSE on IWB as a multistage process comprising creativity and IWB.

Design/methodology/approach

The research adopted a cross-sectional research design to establish the hypothetical influence of CSE on innovative work behavior and collected data at one point in time. The researchers used regression analysis to establish the influence of CSE on IWB using a sample of teaching staff selected from Ugandan public Universities.

Findings

The findings reveal that CSE has a significant effect on creativity as the first step in the innovation process. The results further revealed that CSE has a statistically significant influence on IWB.

Research limitations/implications

The researchers collected data from public Universities, and the application of the findings may fall short when applied to a setting of private universities. Therefore, future research can consider a setting of private universities to replicate the current study findings. The study was cross-sectional, and yet employees' CSE and innovation behavior may change over time. This study opens grounds for longitudinal research in the same research area.

Practical implications

The study shapes direction for practicing managers to resiliently strategize for enhancing creative self-efficacy of employees to promote IWB. Specifically, our study indicates that organizations must enhance positive organizational behavior like CSE to enhance employees' ability to resiliently overcome the fear of uncertainty associated with innovation. While devising the intervention strategies geared towards enhancing CSE, organizations need to consider the stage of IWB required whether at creativity or innovation stage of the innovative behavior.

Originality/value

This research is empirically and theoretically valuable. This is an original study to establish a direct causal influence of CSE on creativity and IWB using a sample drawn from public Universities in the context of a developing Country. Theoretically, the study expands on the applicability of the social cognitive theory (SCT) by revealing that the influence of an individual's personality characteristics like CSE varies with the stage of IWB because the tasks involved in the various types of IWB differ and thus the magnitude of influence varies.

Abstract

Purpose

This paper aims to provide an innovative solution on new service development (NSD) implementation by the project management competences and processes of IPMA ICB 3.0 and PMI PMBOK Guide 5th E.

Design/methodology/approach

By breaking NSD work breakdown structure into five control accounts, each account has its own suggested work packages concluded from reviewed literatures.

Findings

This research sequentially presents proper PM competences and processes as solutions for these control accounts and their work packages.

Research limitations/implications

This study was to provide an innovative solution on NSD implementation by the project management competences and processes of IPMA ICB 3.0 and PMI PMBOK Guide 5th E. By breaking NSD work breakdown structure into five control accounts, each account has its own suggested work packages concluded from reviewed literatures. This research sequentially presents proper PM competences and processes as solutions for these control accounts and their work packages. Consequently, we concluded that the PM competences and processes furnish a favorable base where any NSD project is suitable to deploy without compromising its original features.

Practical implications

Consequently, it is concluded that the PM competences and processes furnish a favorable base where any NSD project is suitable to deploy without compromising its original features.

Abstract

Purpose

The current diversity in organizations requires innovative employees to cope up with the dynamism. A burgeoning body of literature has established the antecedent role of self-efficacy in employee innovativeness. However, there is a dearth of knowledge regarding the influence of self-efficacy on the different types of innovative work behaviour. The purpose of this study was to establish the influence of self-efficacy on the different types of innovative work behaviour.

Design/methodology/approach

The study adopted an explanatory design to examine the hypothesized relationship between the study variables. Regression analysis was used to investigate the relationship between self-efficacy and different types of innovative work behaviour using a sample drawn from public universities in Uganda.

Findings

The study findings reveal that self-efficacy significantly influences the four types of innovative work behaviour. However, the magnitude of the influence is not uniform across the four types of innovative work behaviour. Idea implementation was highly influenced by self-efficacy, followed by generation of ideas. Championing and exploration are the least determinants of self-efficacy.

Originality/value

This research has both empirical and theoretical value. Empirically, to the best of the authors’ knowledge, this is the first study to show a direct relationship between self-efficacy and individual facets of innovative work behaviour in a public university setting in a developing nation like Uganda. Theoretically, the study expands on the applicability of the social cognitive theory by revealing that the influence of an individual's personality characteristics (such as self-efficacy) varies with the type of innovative work behaviour because the tasks involved in the various types of innovative work behaviour differ and are thus affected by self-efficacy differently. The study limitations and areas for further research are discussed.
