Abstract

Purpose

The purpose of this study is to determine the steady state of an electromagnetic structure using the finite element method (FEM) without calculation of the transient state. The proposed method permits to reduce the computation time if the transient state is important.

Design/methodology/approach

In the case of coupling magnetic and electric circuit equations to obtain the steady state with periodic conditions, an approach can be to discretise the time with periodic conditions and to solve the equation system. Unfortunately, the computation time can be prohibitive. In this paper, the authors proposed to use the waveform relaxation method associated with the Newton method to accelerate the convergence.

Findings

The obtained results show that the proposed approach is efficient if the transient state is important. On the contrary, if the transient state is very low, it is preferable to use the classical approach, namely, the time-stepping FEM.

Research limitations/implications

The main limitation of the proposed approach is the necessity to evaluate or to know the time constant and consequently the duration of the transient state. Moreover the method requires some important memory resources.

Practical/implications

In the context of the use of the time-stepping FEM, one of the problems is the computation time which can be important to obtain the steady state. The proposed method permits avoidance of this difficulty and directly gives the steady state.

Social/implications

The proposed approach will permit to model and study the electromagnetic systems in the steady state, and particularly the transformers. Because of the gain in computing time, the use of optimisation techniques will be facilitated.

Originality/value

The novelty of this study is the proposal of the waveform relaxation–Newton method to directly obtain the steady state when applied to the three-phase transformer.

Abstract

Purpose

While companies in developed countries are increasingly turning to indigenous employees, integration measures have met with mixed results. Low integration can lead to breach of the psychological contract, i.e. perceived mutual obligations between employee and employer. The purpose of this paper is to identify how leadership and organizational integration measures can be implemented to promote the perceived insider status (PIS) of indigenous employees, thereby fostering fulfillment of the psychological contract.

Design/methodology/approach

A search for relevant literature yielded 128 texts used to identify integration measures at the level of employee–supervisor relationships (leader-member exchanges, inclusive leadership) and at the level of employee–organization relationships (perceived organizational support, pro-diversity practices).

Findings

Measures related to leadership included recruiting qualified leaders, understanding cultural particularities, integrating diverse contributions and welcoming questions and challenges. Organizational measures included reaching a critical mass of indigenous employees, promoting equity and participation, developing skills, assigning meaningful tasks, maintaining good work relationships, facilitating work-life balance, providing employment security, fostering support from communities and monitoring practices.

Originality/value

While PIS has been studied in western and culturally diverse contexts, it has received less attention in indigenous contexts. Yet, some indigenous cultural values are incompatible with the basic assumptions of mainstream theories. Furthermore, colonial policies and capitalist development have severely impacted traditional indigenous economic systems. Consequently, indigenous people are facing many barriers to employment in ways that often differ from the experiences of other minority groups.

Abstract

Purpose

The aim of this paper is to reduce the evaluations number of the fine model within the output space mapping (OSM) technique in order to reduce their computing time.

Design/methodology/approach

In this paper, n-level OSM is proposed and expected to be even faster than the conventional OSM. The proposed algorithm takes advantages of the availability of n models of the device to optimize, each of them representing an optimal trade-off between the model error and its computation time. Models with intermediate characteristics between the coarse and fine models are inserted within the proposed algorithm to reduce the number of evaluations of the consuming time model and then the computing time. The advantages of the algorithm are highlighted on the optimization problem of superconducting magnetic energy storage (SMES).

Findings

A major computing time gain equals to three is achieved using the n-level OSM algorithm instead of the conventional OSM technique on the optimization problem of SMES.

Originality/value

The originality of this paper is to investigate several models with different granularities within OSM algorithm in order to reduce its computing time without decreasing the performance of the conventional strategy.

Abstract

Purpose

Under current market conditions of corporate foresight, turbulence is a key element of the business landscape. Turbulence can be summarised using the trendy managerial acronym “VUCA”: volatility, uncertainty, complexity and ambiguity. This paper aims to combine, for the first time, scientific discussion of technological disruption with the VUCA approach. Gartner Hype Cycle is used as a case example of technological turbulence and “vucability”.

Design/methodology/approach

First, the authors present the key concepts of technological disruption and radical innovation. Both these concepts are highly relevant for modern corporate foresight. Second, the authors discuss the key elements of current technological transformation and summarise it to create a bigger picture. Third, the authors link this discussion to the VUCA approach. Fourth, the authors present the new corporate foresight framework, which is highly relevant for corporations and takes current technological transformation more seriously than previous proposals, which expect more stable business and a technological landscape.

Findings

Key issues in modern VUCA management are agility (response to volatility), information and knowledge management (response to uncertainty), restructuring (response to complexity) and experimentation (response to ambiguity). Useful foresight tools are challenging tools, decision-making tools, aligning tools, learning tools and the ability to combine these management tools in the practices of corporate foresight and management systems. The VUCA approach is a key solution concept to technological disruption.

Practical implications

The authors present the new corporate foresight framework and management tool based on foresight, which help leaders to manage VUCA – especially under the conditions of hyper-competition and technological disruption.

Originality/value

Corporate leaders should reinvent the strategic planning framework and adjust it to the VUCA conditions and simply be more strategic. Traps and typical failures of foresight are adopting it too early, giving up too soon, adapting too late and hanging on too long. In particular, technological transformation with disruptive technologies is changing and challenging many basic assumptions of business management and strategic planning. Our comparative analysis with Gartner Hype Cycle (fast technological changes from 2008 to 2016) verifies this important aspect of technological disruption.

Abstract

Purpose

This paper aims to describe the nature and significance of Sorel’s cooking appliance and to examine the promotion and marketing options used by Sorel to make it an appliance that was “widely used in private residences and by small eating houses.” It will highlight the role of the individual and will demonstrate that marketing and promotion strategies that are modulated by the social ambitions of the manufacturer.

Design/methodology/approach

The basis of this research is extensive quantitative and qualitative analysis of primary sources, mainly the advertisements placed by Sorel, supported by information in contemporary newspapers and journals.

Findings

Stanislas Sorel’s invention of an early form of thermostat allowed him to develop a stove that could cook a four-course family dinner largely unsupervised, an invention which was poised to revolutionise the lives of many households. Sorel was primarily an inventor striving for acceptance in the scientific world, with limited skills in the commercialisation of his inventions. His promotion and marketing efforts reflect both the social realities of the time and his own ambitions.

Originality/value

There has been very little research into the way small French inventors and manufacturers approached the marketing of their products. The paper provides a unique insight into the promotion techniques of a mid-nineteenth-century French inventor-cum-entrepreneur and highlights the role of the individual and how actions are constrained by ambition and opportunity. The paper provides an example of how research into how specific individuals can inform the larger history of marketing.

Abstract

Purpose

The primary goal of this article is to review the existing studies and offer clarity regarding the association between social media adoption and youth civic engagement.

Design/methodology/approach

This research systematically summarizes and reviews 42 original articles published from 2010 to 2019 with an objective of offering insightful results. Additionally, a theoretical framework was carefully designed by adopting various conceptions from citizen participation and computer-mediated communication research literature.

Findings

The findings demonstrate that social media usage could generally have a positive correlation with civic participation among younger generations. Moreover, the result also highlights that certain functional features of social media uses including using social media for news consumption and expression could significantly predict civic engagement.

Originality/value

Despite the ever-growing importance of social media technologies, investigations on their differential, nonlinear and even inconsistent effects on civic engagement remain theoretically ambiguous and empirically unsubstantiated. The study represents one of the first scholarly attempts to review, summarize and analyze the extant research evidence from the past ten years.
