Abstract

Purpose

The purpose of this paper is to propose a physics-aware algorithm to obtain radio frequency (RF)-reduced models of micro-electromechanical systems (MEMS) switches and show how, together with multiphysics macromodels, they can be realized as circuits that include both lumped and distributed parameters.

Design/methodology/approach

The macromodels are extracted with a robust procedure from the solution of Maxwell’s equations with electromagnetic circuit element (ECE) boundary conditions. The reduced model is extracted from the simulations of three electromagnetic field problems, in full-wave regime, that correspond to three configurations: signal lines alone, switch in the up and down positions.

Findings

The technique is exemplified for shunt switches, but it can be extended for lateral switches. Moreover, the algorithm is able take frequency dependence into account both for the signal lines and for the switch model. For the later, the order of the model is increased until a specified accuracy is achieved.

Originality/value

The use of ECE as boundary conditions for the RF simulation of MEMS switches has the advantage that the definition of ports is unambiguous and robust as the ports are clearly defined. The extraction approach has the advantage that the simplified model keeps the basic phenomena, i.e. the propagation of the signal along the lines. As the macromodel is realized with a netlist that uses transmission lines models, the lines’ extension is natural. The frequency dependence can be included in the model, if needed.

Abstract

The purpose of this study is to explore how the “New type of industry and research chain value creation project” promoted by the Ministry of Science and Technology in Taiwan can help universities to achieve university social responsibility (USR), promote social innovation, and achieve sustainable development. The university social responsibility defined in this study is proposed through literature analysis. The study interviewed three professionals who actually participated in the project and served as core positions. Semi-structured in-depth interviews were conducted. Key findings are drawn as follows. First, the term USR is multifaceted and needs further refinement in light of the changing and dynamic roles of universities. Second, the value creation plan helps universities achieve social responsibility. Third, the value creation team incorporates the concept of university social responsibility into the consideration of development factors, which contributes to the sustainability of the project. Fourth, the value creation plan faces the willingness of participants and the public's unclear understanding of university social responsibility. Finally, practical benefits include the joy of team members, the cultivation of talents and the dream of having a business.

Abstract

Purpose

This paper aims to explore the relationships among several key constructs which link the individual’s motivation for knowledge acquisition to his affiliation with online knowledge networks, to further access the intellectual capital of the network as a prerequisite for organizational achievement.

Design/methodology/approach

An online survey with 227 members of higher education and research centers from 30 countries was carried out between July and September 2021. The data were analyzed by means of partial least squares structural equation modeling technique, using the statistics software package SmartPLS 3.0.

Findings

Individual motivation to acquire knowledge has a significant influence on the affiliation with online academic networks approached as online knowledge networks. Further, active engagement with the network’s intangible resources leads to a significant harnessing of the three-component intellectual capital, that is, human, structural and relational capital. Human and relational capital is proven to exert a significant effect on organizational achievements, whereas structural capital falls short of reporting a meaningful influence on the dependent variable.

Research limitations/implications

This research adds new knowledge to the capitalization of online knowledge networks and its influence on organizational achievements via intellectual capital.

Originality/value

A novel perspective is advanced in which online knowledge networks are acknowledged as a pivotal bond and nonlinear integrator between the individual level of knowledge fields and organizational knowledge leveraged into organizational achievements.

Abstract

Purpose

The purpose of the present research is to introduce a combined framework that integrates innovative work behavior, product innovation process and customer knowledge management; then, to explore the mediating effect of customer knowledge management in the relationship between innovative work behavior and the product innovation process.

Design/methodology/approach

The basis for the present research is a cross-sectional design. Data collection from 154 employees occurred using the following structured questionnaires: Customer Knowledge Management (CKM), Innovative Work Behavior (IWB) and Product Innovation Process (PIP). Data processing used SPSS version 26.0, including the PROCESS (3.5) macro analysis.

Findings

The results show positive relationships between innovative work behavior and the product innovation process (r = 0.420, p < 0.01). Pearson's correlation shows a coefficient of 0.42, meaning that 42% of the variations in perceived product innovation are due to variations in innovative work behavior. The second condition of the mediation test involved testing the relationship between the independent variable (Innovative Work Behavior) and the mediating variable (Knowledge Management) and showed a significant relationship (r = 0.272, p < 0.01). The findings suggested that knowledge management that other determinants supported, such as collaboration in idea exploration, idea championing and encouragement of participation in idea implementation, significantly contributed to the product innovation process (r = 0.509, p < 0.01). The bootstrapping method confirmed that innovative work behavior supports product innovation through the mediation of customer knowledge management (z = 3.01, p = 0.002).

Research limitations/implications

The cross-sectional design, along with the relatively low number of participants and the self-reporting nature of the questionnaires, represent the current study's main limitations. Developing the research model could integrate new variables, such as customer co-creation processes, performance-based compensation, employee citizenship activities and transformational leadership.

Practical implications

This research has both theoretical and practical implications. These emphasize the importance of further investigation into the factors influencing companies' innovation processes. They also provide managers with a means of finding a fit between the deployment of customer knowledge mechanisms and the achievement of innovative workplace behavior, to improve innovation process efficiency.

Originality/value

The current study broadens the empirical research area of customer knowledge management and its impact on both innovative work behavior and the product innovation process, particularly in knowledge-intensive market scenarios that require organizations to be innovative.

Abstract

Purpose

The purpose of this paper is to investigate the generation of civic and public (C&P) engagement as an integrative outcome of a proper balance between emotional, rational and spiritual knowledge, via the mediation of interpersonal competencies.

Design/methodology/approach

The empirical analysis relies on a questionnaire-based survey conducted with 294 respondents from two knowledge-intensive organizations. Structural equation modeling, using Smart PLS 4, is used to analyze the data.

Findings

Individual knowledge can be considered as the refined outcome of the underlying transformations of various knowledge sources and resources, which is apposite for the next level of knowledge workers’ acumen. Individual knowledge – which relies on a good balance of rational, emotional and spiritual knowledge – exerts a positive effect on interpersonal competencies, wherein the latter positively influences the C&P engagement of knowledge workers.

Research limitations/implications

Policymakers should capitalize on the development of strong interpersonal competencies; they should be able to understand the social mechanisms of motivating people, of stimulating, harnessing and channeling individual knowledge toward higher C&P as a prerequisite of value creation.

Originality/value

To the best of the authors’ knowledge, this is the first argumentative undertaking intended to explore the conversion of the three knowledge types into individual knowledge as a premise of interpersonal competencies development and as a relevant antecedent of C&P engagement. The results of this paper support that achieving balance in one's life is essential for increasing interpersonal competencies and C&P engagement. This study not only represents the first contribution to this debate but also helps managers and organizations to recognize that a good balance requires emotional, rational and spiritual knowledge.

This study aims to explore the relationship between different categories of motivation and the intention to engage in collaborative consumption (CC), using attitude as a mediator.

Abstract

Purpose

This study aims to explore the relationship between different categories of motivation and the intention to engage in collaborative consumption (CC), using attitude as a mediator.

Design/methodology/approach

The authors extend an existing measurement scale focused on sustainability, enjoyment, reputation and economic benefits, as factors relevant in shaping how people perceive CC. The extension includes the role of personal beliefs and social relationships. The authors conduct a mediation analysis using partial least squares path modelling.

Findings

This study partially confirms existing literature: sustainability and enjoyment are positively related and statistically significant in predicting attitude towards CC, while only enjoyment impacts behavioural intention; attitude further impacts behavioural intention. Further, reputation and economic benefits positively and significantly impact attitude; economic benefits are not significant for behavioural intention in this study’s Romanian sample, but reputation is. Neither beliefs nor relationships are significantly associated with behavioural intention.

Originality/value

The authors investigate CC determinants in a post-communist economy, a novel setting for the development of sharing economy, as most studies focus on traditionally developed economies.
