Abstract

Purpose

The paper presents an application of the scaling theory in a description of energy losses in soft magnetic materials in order to improve an agreement between measurements and theoretical models.

Design/methodology/approach

The scaling theory allows the description of energy losses by a generalized homogenous function, which depends on scaling exponents α, β and amplitudes Γ(n). The values of the scaling exponents and amplitudes were estimated on the basis of measurement data of total energy losses.

Findings

The main findings of the paper are: the linear relationships between the scaling exponents α and β, the data collapse of energy losses and the scaling laws for asymptotic exponents of energy losses derivatives.

Research limitations/implications

The origin of the data collapse and the relationship between the scaling exponents will be the subject of further research with the aid of renormalization group method

Practical implications

The paper could be useful both for device designers and researchers involve in computational electromagnetism. Particularly, the data collapse allows a comparison of energy loss values measured in laboratories on different samples and by different methods.

Originality/value

The application of the scaling theory in a description of energy losses in soft magnetic materials improves an agreement between measurement and theoretical models.

Abstract

Purpose

The scaling up of promising, innovative integration projects presents challenges to social and health care systems. Evidence that a new service provides (cost) effective care in a (pilot) locality can often leave us some way from understanding how the innovation worked and what was crucial about the context to achieve the goals evidenced when applied to other localities. Even unpacking the “black box” of the innovation can still leave gaps in understanding with regard to scaling it up. Theory-led approaches are increasingly proposed as a means of helping to address this knowledge gap in understanding implementation. Our particular interest here is exploring the potential use of theory to help with understanding scaling up integration models across sites. The theory under consideration is Normalisation Process Theory (NPT).

Design/methodology/approach

The article draws on a natural experiment providing a range of data from two sites working to scale up a well-thought-of, innovative integrated, primary care-based dementia service to other primary care sites. This provided an opportunity to use NPT as a means of framing understanding to explore what the theory adds to considering issues contributing to the success or failure of such a scaling up project.

Findings

NPT offers a framework to potentially develop greater consistency in understanding the roll out of models of integrated care. The knowledge gained here and through further application of NPT could be applied to inform evaluation and planning of scaling-up programmes in the future.

Research limitations/implications

The research was limited in the data collected from the case study; nevertheless, in the context of an exploration of the use of the theory, the observations provided a practical context in which to begin to examine the usefulness of NPT prior to embarking on its use in more expensive, larger-scale studies.

Practical implications

NPT provides a promising framework to better understand the detail of integrated service models from the point of view of what may contribute to their successful scaling up.

Social implications

NPT potentially provides a helpful framework to understand and manage efforts to have new integrated service models more widely adopted in practice and to help ensure that models which are effective in the small scale develop effectively when scaled up.

Originality/value

This paper examines the use of NPT as a theory to guide understanding of scaling up promising innovative integration service models.

Abstract

The root of urban poverty and inequality often results from limited economic opportunity. Yet, often this perception of lack of opportunity is centered on the early stages of new venture formation, with only limited attention to venture growth and expansion. In this study, we explore the intersection of social venturing and community economic redevelopment to address this gap in the literature. We examine how venturing under conditions of limited economic opportunities occurs not just at the formation stages but also throughout the venturing life cycle. Specifically, we examine how ventures formed in distressed, urban neighborhoods face unique challenges when scaling up their operations. These challenges relate to securing and leveraging four types of capital: financial, physical, human, and social. We employ a case study methodology to examine these scaling challenges and the strategies the organization employed to overcome location disadvantages.

Abstract

The work described in this paper is part of a current programme that has two objects: (1) to investigate further the reasons for the different scaling behaviour of steel in steam and carbon dioxide, although these gases have similar oxygen potentials; (2) to provide background information for an investigation into the effect of variations in re‐heating furnace atmospheres upon scaling and scale adhesion.

Abstract

Purpose

This paper aims to use a scaling approach to scale the solutions of a beforehand-simulated finite element (FE) solution of an induction machine (IM). The scaling procedure is coupled to an analytic three-node-lumped parameter thermal network (LPTN) model enabling the possibility to adjust the machine losses in the simulation to the actual calculated temperature.

Design/methodology/approach

The proposed scaling procedure of IMs allows the possibility to scale the solutions, particularly the losses, of a beforehand-performed FE simulation owing to temperature changes and therefore enables the possibility of a very general multiphysics approach by coupling the FE simulation results of the IM to a thermal model in a very fast and efficient way. The thermal capacities and resistances of the three-node thermal network model are parameterized by analytical formulations and an optimization procedure. For the parameterization of the model, temperature measurements of the IM operated in the 30-min short-time mode are used.

Findings

This approach allows an efficient calculation of the machine temperature under consideration of temperature-dependent losses. Using the proposed scaling procedure, the time to simulate the thermal behavior of an IM in a continuous operation mode is less than 5 s. The scaling procedure of IMs enables a rapid calculation of the thermal behavior using FE simulation data.

Originality/value

The approach uses a scaling procedure for the FE solutions of IMs, which results in the possibility to weakly couple a finite element method model and a LPTN model in a very efficient way.

Abstract

Purpose

To ensure that more people will benefit from integrated care initiatives, scaling-up of successful initiatives is the way forward. However, new challenges present themselves as knowledge on how to achieve successful large-scale implementation is scarce. The EU-funded project SCIROCCO uses a step-based scaling-up strategy to explore what to scale-up, and how to scale-up integrated care initiatives by matching the complementary strengths and weaknesses of five European regions involved in integrated care. The purpose of this paper is to describe a multi-method evaluation protocol designed to understand what factors influence the implementation of the SCIROCCO strategy to support the scaling-up of integrated care.

Design/methodology/approach

The first part of the protocol focuses on the assessment of the implementation fidelity of the SCIROCCO step-based strategy. The objective is to gain insight in whether the step-based strategy is implemented as it was designed to explore what works and does not work when implementing the scaling-up strategy. The second part concerns a realist evaluation to examine what it is about the SCIROCCO’s strategy that works for whom, why, how and in which circumstances when scaling-up integrated care.

Findings

The intended study will provide valuable information on the implementation of the scaling-up strategy which will help to explain for what specific reasons the implementation succeeds and will facilitate further improvement of project outcomes.

Originality/value

The expected insights could be useful to guide the development, implementation and evaluation of future scaling-up strategies to advance the change towards more sustainable health and care systems.

Abstract

Purpose

This study aims to explore the behavioral patterns of entrepreneurs, their cognitive styles and personality characteristics that can lead to a self-destructive chain of events during the transition from a fledgling business to one capable of long-term, profitable growth. This study adopts the self-regulation attitude theory to uncover the reasons for premature start-up scaling, which will help founders to study on their cognitive biases, emotions and behaviors and make efforts to do what does not come naturally to them.

Design/methodology/approach

The respondents for this qualitative study were selected from a group of entrepreneurs with extensive experience with technology start-ups that have either failed or succeeded during their development stages. In-depth semi-structured interviews were conducted with eight participants, who were selected through snowball sampling, on the theme of understanding “How do premature scaling mistakes happen?”. Thematic analysis was used to unearth common themes.

Findings

The results of this study identified the following themes, “comparison,” “emotional over-reaction,” “impatience,” “mistaken customer priorities,” “overestimation” and “overconfidence,” which eventually leads to premature scaling. The underlying decision-making heuristics of entrepreneurs can be identified as engulfed in different cognitive biases and emotions resulting in negative behavioral patterns, as in the case of premature scaling. Of the six themes, “comparison,” “mistaken customer priorities,” “overestimation” and “overconfidence relates to cognitive bias” and “emotional over-reaction” and “impatience” relate to emotional factors.

Research limitations/implications

The study was made possible with the support of the voluntary participants chosen by purposive and snowballing data sampling. The interviewee and interviewer biases could have also crept in as part of this qualitative approach. The study pertains only to start-ups in the information technology sector and further studies need to be done to generalize the results across industries as well.

Practical implications

This early-stage underestimation of unexpected obstacles in the entrepreneurship journey necessitates a focus on the entrepreneur too, as much as the concept. In these hectic and fast-paced circumstances, aspiring entrepreneurs must be taught how to deal objectively with themselves and others, as well as think strategically. Leaders who scale do so because they take purposeful measures to overcome their weaknesses through self-discipline, soliciting advice from others and using their right to change their attitude and points of view.

Originality/value

The study frames the new approach into the entrepreneurial literature, linking it to self-regulation attitude theory and adds to the nascent literature on neuroentrepreneurship which discuss entrepreneurial cognition, decision-making, and entrepreneurial behavior. This study attempted to explore the reasons behind the premature scaling of startups on an individual level. This study is pioneering in exploring the cognitive factors underlying an entrepreneur’s decision that results in premature scaling. This study provides insights for academicians, entrepreneurs and policymakers and helps understand the cognitive journey that leads to premature scaling.

Abstract

Purpose

The purpose of this paper is to discuss about evaluating the integrals involving B-spline wavelet on the interval (BSWI), in wavelet finite element formulations, using Gauss Quadrature.

Design/methodology/approach

In the proposed scheme, background cells are placed over each BSWI element and Gauss quadrature rule is defined for each of these cells. The nodal discretization used for BSWI WFEM element is independent to the selection of number of background cells used for the integration process. During the analysis, background cells of various lengths are used for evaluating the integrals for various combination of order and resolution of BSWI scaling functions. Numerical examples based on one-dimensional (1D) and two-dimensional (2D) plane elasto-statics are solved. Problems on beams based on Euler Bernoulli and Timoshenko beam theory under different boundary conditions are also examined. The condition number and sparseness of the formulated stiffness matrices are analyzed.

Findings

It is found that to form a well-conditioned stiffness matrix, the support domain of every wavelet scaling function should possess sufficient number of integration points. The results are analyzed and validated against the existing analytical solutions. Numerical examples demonstrate that the accuracy of displacements and stresses is dependent on the size of the background cell and number of Gauss points considered per background cell during the analysis.

Originality/value

The current paper gives the details on implementation of Gauss Quadrature scheme, using a background cell-based approach, for evaluating the integrals involved in BSWI-based wavelet finite element method, which is missing in the existing literature.

Abstract

Purpose

The purpose of this paper is to examine sustainability-related challenges in the two Western Balkan countries – Albania and Kosovo. It discusses the opportunities of local higher education institutions (HEIs) taking responsibility to tackle these challenges by providing professional development through science–society collaboration in innovative training sessions for university educators.

Design/methodology/approach

A literature review on actual challenges and transformations of higher education for sustainable development (ESD) in Albania and Kosovo will be the starting point of this paper. Subsequently, experiences from the on-going European Union (EU) project “ConSus” will be used to draw both a competence framework for ESD within science–society collaboration based on the training sessions, as well as possible scaling opportunities.

Findings

The paper draws possible approaches of training sessions for university educators promoting sustainable development and science–society collaboration in higher education. They will be concluded by addressing possible scaling opportunities of the project’s activities.

Practical implications

The experiences of the ConSus training sessions will outline competences of university educators in ESD gained in relation to transdisciplinary collaboration in research and teaching.

Originality/value

The paper will contribute to ESD approaches in higher education in Albania and Kosovo. Furthermore, scaling possibilities will be discussed to systematically implement ESD approaches also in higher hierarchical levels and other HEIs.
