Abstract
Purpose
The purpose of this paper is to introduce a simplified method, based on an improvement to the actual second‐order approximation to magnetic hysteresis curves, to calculate an estimation of quasi‐static hysteresis loops of ferromagnetic materials.
Design/methodology/approach
The addition of a new dB(B) function is proposed to second‐order rational approximation for the upward and downward magnetic quasi‐static hysteresis loop. The new semi‐empirical approach is tested with typical cycles of commercial Ni‐ferrites (ferroxcube) and Ni standards using a vibrating sample magnetometer (VSM).
Findings
The model is simple and a fast tool to reproduce with reasonable accuracy the hysteresis loops based on appropriate parameters of materials under analysis. The proposed extension to the Rivas model has reduced the maximum difference between experimental and modeled values from 19 to 0.08 per cent in the approximation to different hysteresis cycles of the magnetic materials studied here.
Originality/value
This paper presents an improvement to second‐order rational functions approach for fitting of hysteresis loops with simple added functions.

Abstract
Purpose
The first aim of the chapter is to offer a characterization of back-reshoring as a possible step of the firm’s nonlinear internationalization process. The second aim is to review the empirical literature on back-reshoring and to complement it with the findings of an extensive data collection.
Methodology/approach
In this chapter we adopted an explorative approach building on both theoretical and empirical literature from the fields of international business and international operations Management. We also collected secondary data on back-reshoring decisions in order to define the magnitude of the investigated phenomenon and to offer a primary characterization.
Findings
Our findings confirm that, though it cannot be considered a generalized trend, back-reshoring is a very topical issue for international business scholars. It represents an autonomous phenomenon consistent with the idea of nonlinear internationalization process.
Research limitations/implications
The chapter is based on cross-sectional data. Longitudinal research is required in order to address the proposed research questions and help understanding “how much” and what kind of manufacturing will be housed in western countries in the near future.
Originality/value
This is the first attempt to conceptualize back-reshoring as a possible step of the firms’ internationalization process. It is also the first chapter that summarizes and discusses the literature and empirical evidence on back-reshoring emerging from a wide range of countries.

Abstract
Introduction: Artificial intelligence (AI) has progressed significantly over the past few years, evolving into a collection of innovative tools that provide a competitive advantage to businesses. The acceptance and investment in AI are skyrocketing over the globe. The entry of AI in the workplace automates tasks and impacts making a timely decisions. At the same time, the workforce is not ready to welcome the new technology due to the skill gap. The organisation has to face many challenges in reskilling and convincing the workforce to incorporate AI in their work.
Purpose: With this study, the authors aim to analyse and highlight the introduction of AI in the organisation and the call for the reskilling of the workforce. To figure out what skills are most important for employees to learn to advance their careers.
Methodology: Given the deductive nature of the study, the researchers used secondary data collected and compiled from research papers, publications, websites, HR blogs, survey reports, etc. Research papers from reputed journals, reports of consultancies and agencies have been considered to synthesise the information and present it in a systematic manner and to derive the conclusion.
Findings: The findings indicate AI’s capabilities and applications have grown considerably, which shows the importance of AI in a growing number of fields, yet several hurdles need to be overcome, the most prominent one being the issues concerning upskilling the workforce for the future of AI. This study reveals the change in the perceived importance of the skills in the present and future times. Reskilling and upskilling the workforce and creating new talent to meet the changing employment demands is becoming increasingly important.

Abstract
Purpose
The purpose of this paper is to present a ribbons production route of composition Fe78Si9B13 (%at.) using low cost noncommercial scrap materials to obtain usable magnetic cores by melt spinning technique and their characterization. This way, these may compete with the materials produced by conventional casting processes.
Design/methodology/approach
The methodology is to design a master alloy with scrap different starting compositions, to which Fe is added to get the desired atomic ratio of components. With this starting alloy, using the method of melt spinning, in its variant of chill block melt spinning, are achieved amorphous ribbons with desired soft magnetic behavior. Then these ribbons are thermally treated for achieve nanocrystalline structures to improve the performance in the magnetic cores.
Findings
The result of this paper shows that it is possible to recycle scrap materials, and re-used efficiently as components essential in part of electrical components. This way, these may compete with the materials produced by conventional casting processes.
Research limitations/implications
The limitation of this work to ensure that the scrap materials used is reasonably adequate to accomplish obtaining the master alloy, i.e. having reduced impurities.
Practical implications
The implications are important, because it assures that the components are recyclable and also high-tech in reference to energy saving that involves the production of amorphous and nanocrystalline materials in the electric industry. These products may compete with those produced by conventional casting processes.
Social implications
The social implications lead to awareness in recycling and energy saving as an option for social progress in technology.
Originality/value
The originality of the study is that it takes as a starting point for the final product (ribbon) noncommercial scrap materials of known composition and the obtained results are comparable to those that also are manufactured from the pure elements. The control of impurities is necessary in the production route. This way, these may compete with the materials produced by conventional casting processes. This process achieved a production with lower cost, high efficient energy products and high added value.

Abstract
Purpose
The purpose of this paper is to present an analysis over own and other authors data related to the process of Chill Block Melt Spinning (CBMS) and propose a model of analysis for interpreting.
Design/methodology/approach
The methodology used in this work is to present the data analyzed by other authors, organize own data similarly to establish comparison, and established models and propose a possible physical processes interpretation.
Findings
Similarity between own experimental data. with others data reported by other authors, both z/w ratio and the thicknesses of the films produced has been found. This allows us to establish an exponential decay of the parameters studied and possibly link it the Newtonian cooling to which the samples are subjected in its production.
Research limitations/implications
This work is the first model set up to predict dimensions in design process by CBMS as a function of parameters of the ribbon production process.
Practical implications
The prediction of the product dimensions, with adjusting the initial parameters, allows to improve the process of ribbon production, this saves tuning time of the machine and provides certainty in the molten material ejection.
Social implications
The efficient production of magnetic materials lets save efforts in the raw material process preparing in magnetic cores for the energy sector. This, improves production besides benefit society by the final product and the energy savings.
Originality/value
The value of this paper is to propose a model of analysis that allows standardize production parameters, and could even allow the use of these models in computer programs, process simulators in a more effective manner.

Abstract
The world of management and technology has become accustomed to the notion of “2.0” advancements and transformative innovations. Is the field of Change Management/Organizational Development itself in this story? Not enough! We re-examine the field’s foundational beliefs, practices, focus, research directions, and value add. We conclude that there is strong evidence from the front line and from an IBM Case Study that the field must “reboot” – to rethink our methods and frameworks; the role and skills of change leadership for the future; change practitioner capabilities for the future; the metrics needed to evaluate progress; and the knowledge exchange between Academe and practitioners.
