Abstract

Purpose

The purpose of this paper is to report on the developments in manufacturing soft magnetic materials using laser powder bed fusion (L-PBF).

Design/methodology/approach

Ternary soft magnetic Fe-49Co-2V powder was produced by gas atomization and used in an L-PBF machine to produce samples for material characterization. The L-PBF process parameters were optimized for the material, using a design of experiments approach. The printed samples were exposed to different heat treatment cycles to improve the magnetic properties. The magnetic properties were measured with quasi-static direct current and alternating current measurements at different frequencies and magnetic flux densities. The mechanical properties were characterized with tensile tests. Electrical resistivity of the material was measured.

Findings

The optimized L-PBF process parameters resulted in very low porosity. The magnetic properties improved greatly after the heat treatments because of changes in microstructure. Based on the quasi-static DC measurement results, one of the heat treatment cycles led to magnetic saturation, permeability and coercivity values comparable to a commercial Fe-Co-V alloy. The other heat treatments resulted in abnormal grain growth and poor magnetic performance. The AC measurement results showed that the magnetic losses were relatively high in the samples owing to formation of eddy currents.

Research limitations/implications

The influence of L-PBF process parameters on the microstructure was not investigated; hence, understanding the relationship between process parameters, heat treatments and magnetic properties would require more research.

Originality/value

The relationship between microstructure, chemical composition, heat treatments, resistivity and magnetic/mechanical properties of L-PBF processed Fe-Co-V alloy has not been reported previously.

Abstract

Purpose

The purpose of this paper is to identify requirements and tradeoffs on logistics services for enhanced circularity of materials and resources.

Design/methodology/approach

Based on multiple case study design and abductive reasoning, the study investigates 13 different product categories. The data were analyzed based on theoretical, a priori codes from the literature review. Inductive, emerging codes were added to the coding scheme during the analysis.

Findings

Requirements of logistics services to support slowing of resource flows are categorized with respect to initiator, location of the service, single or multiple actors, and transportation of parts, products and people. Moreover, the study identifies new logistics tradeoffs: material and people, knowledge and people, and information and knowledge. Transportation of product, people and parts can be reduced by increasing local knowledge and improve information sharing.

Research limitations/implications

This review contributes to the understanding of the relationship between logistics services and enhancement of circularity by highlighting requirements on logistics services in the aftermarket supply chain that support slowing of resource flows. To enhance circularity, logistics services must extend the traditional material information flow with the flow of people and knowledge, respectively.

Practical implications

The categorization provides practitioners and researchers with an overview of requirements and tradeoffs on logistics services to enhance circularity of a particular circular cycle. The implications will provide an opportunity to address environmental impact of transportation and improve the utilization of scarce materials.

Social implications

Variety of tradeoffs in logistics services can enhance slowing and hence circularity of scarce materials.

Originality/value

First, the authors illustrate how traditional tradeoffs in logistics such as flow of materials, resources and people need to be addressed to enhance circularity through slowing. Second, the authors identify two new tradeoffs in logistics services: knowledge flow and degree of customer involvement.

Abstract

Purpose

The purpose of this paper is to describe and explain trauma-informed approaches (TIAs) to mental health. It outlines evidence on the link between trauma and mental health, explains the principles of TIAs and their application in mental health and explores the extent to which TIAs are impacting in the UK.

Design/methodology/approach

The approach is a conceptual account of TIAs including a consideration of why they are important, what they are and how they can become more prevalent in the UK. This is supported by a narrative overview of literature on effectiveness and a scoping of the spread of TIAs in the UK.

Findings

There is strong and growing evidence of a link between trauma and mental health, as well as evidence that the current mental health system can retraumatise trauma survivors. There is also emerging evidence that trauma-informed systems are effective and can benefit staff and trauma survivors. Whilst TIAs are spreading beyond the USA where they developed, they have made little impact in the UK. The reasons for this are explored and ways of overcoming barriers to implementation discussed.

Originality/value

This paper – authored by trauma survivors and staff – describes an innovative approach to mental health service provision that, it is argued, could have immense benefits for staff and service users alike.

Abstract

Purpose

The purpose of this article is to determine the factors in the context of entrepreneurship that are evident in Ecuador, a country that has the highest rate of female entrepreneurship worldwide with 34% according to the Global Entrepreneurship Monitor (GEM) (2019).

Design/methodology/approach

A qualitative study was carried out with 39 cases, applying in-depth personal interviews and focus groups to selected cases in the main cities of Ecuador.

Findings

The results suggest that “mumpreneurship”, copreneurship and sustainable thinking arise in response to the environment. Deepening then in the perspective of the 5M proposes by Brush et al. (2009) that give us a framework of the macroenvironment of women entrepreneurship and offers a holistic understanding of women's entrepreneurship, adding a sixth “M” which is “Environmental Thinking” or the environmental thinking that is present in the current context.

Originality/value

This article is one of the first to analyse the context of female entrepreneurship in Ecuador and determine the context factors that influence the identification of opportunities and the exploitation of entrepreneurial opportunities. It also presents the expectations and challenges of the women who shape the authors’ case studies and give voice to Ecuadorian women. Consequently, this research will support the configuration of policies that supports each of the stages of women's entrepreneurial processes.

Propósito

Este artículo pretende determinar los factores del contexto del emprendimiento que se evidencian en el Ecuador, país que ostenta la tasa más alta de emprendimiento femenino a nivel mundial con un 34% de acuerdo al GEM (2019).

Diseño/metodología/enfoque

Se realizó un estudio cualitativo con 39 casos, aplicando entrevistas personales a profundidad y grupos focales a casos seleccionados en las principales ciudades del Ecuador.

Resultados

Los resultados sugieren que el “mumpreneurship”, el copreneurship y el pensamiento sostenible surgen como respuesta al entorno. Profundizando entonces en la perspectiva de las 5Ms propuesta por Brush et al. (2009) que ofrece una comprensión holística del emprendimiento de mujeres, añadiendo una sexta “M” que es el “Medioambiental Thinking” o el pensamiento ambiental que está presente en el contexto estudiado.

Originalidad/valor

Este artículo es uno de los primeros en analizar el contexto del emprendimiento femenino en Ecuador y determinar los factores del contexto que influyen en la identificación y en la explotación de oportunidades emprendedoras. Además presenta las expectativas y retos de las mujeres que configuran nuestros casos de estudio y dan voz a las mujeres ecuatorianas. En consecuencia nuestra investigación servirá de apoyo para la configuración de políticas que apoyen cada una de las etapas del proceso emprendedor de las mujeres.

Abstract

Purpose

The purpose is explore an approach to acquire, analyze and report data concerning an organizational change initiative that combines knowledge generation and knowledge use, and contrast that with a method where knowledge generation and use is separated. More specifically, the authors contrast a participatory group workshop with individual interviews analyzed with thematic analysis, focusing on information about the change process and its perceived practical relevance and usefulness.

Design/methodology/approach

Participants were managers responsible for implementing a broad organizational change aiming to improve service quality (e.g. access and equity) and reduce costs in a mental health service organization in Sweden. Individual interviews were conducted at two points, six months apart (i1: n = 15; i2: n = 18). Between the interviews, a 3.5-h participatory group workshop was conducted, during which participants (n = 15) both generated and analyzed data through a structured process that mixed individual-, small- and whole-group activities.

Findings

Both approaches elicited substantive information about the content, purpose and process of change. While the content and purpose findings were similar across the two data sources, the interviews described how to lead a change process, whereas the workshop yielded concrete information about what to do. Benefits of interviews included personal insights about leading change while the workshop provided an opportunity for collective sense-making.

Originality/value

When organizational stakeholders work through the change process through a participatory workshop, they may get on the same page, but require additional support to take action.

Abstract

Purpose

This paper aims to present the basic assumptions for creation of social Fröhlich condensate and attract attention of other researchers (both from physics and socio-political science) to the problem of modeling of stability and order preservation in highly energetic society coupled with social energy bath of high temperature.

Design/methodology/approach

The model of social Fröhlich condensation and its analysis are based on the mathematical formalism of quantum thermodynamics and field theory (applied outside of physics).

Findings

The presented quantum-like model provides the consistent operational model of such complex socio-political phenomenon as Fröhlich condensation.

Research limitations/implications

The model of social Fröhlich condensation is heavily based on theory of open quantum systems. Its consistent elaboration needs additional efforts.

Practical implications

Evidence of such phenomenon as social Fröhlich condensation is demonstrated by stability of modern informationally open societies.

Social implications

Approaching the state of Fröhlich condensation is the powerful source of social stability. Understanding its informational structure and origin may help to stabilize the modern society.

Originality/value

Application of the quantum-like model of Fröhlich condensation in social and political sciences is really the novel and original approach to mathematical modeling of social stability in society exposed to powerful information radiation from mass-media and Internet-based sources.

Abstract

Purpose

This integrated care study seeks to highlight how voluntary sector “wellbeing co-ordinators” co-located in a horizontally and vertically integrated, multidisciplinary community hub within one locality of an Integrated Care Organisation contribute to complex, person-centred, co-ordinated care.

Design/methodology/approach

This is a naturalistic, mixed method and mixed data study. It is complementing a before-and-after study with a sub-group analysis of people receiving input from the wider hub (including Wellbeing Co-ordination and Enhanced Intermediate Care), qualitative case studies, interviews, and observations co-produced with embedded researchers-in-residence.

Findings

The cross-case analysis uses trajectories and outcome patterns across six client groups to illustrate the bio-psycho-social complexity of each group across the life course, corresponding with the range of inputs offered by the hub.

Research limitations/implications

To consider the effectiveness and mechanisms of complex system-wide interventions operating at horizontal and vertical interfaces and researching this applying co-produced, embedded, naturalistic and mixed methods approaches.

Practical implications

How a bio-psycho-social approach by a wellbeing co-ordinator can contribute to improved person reported outcomes from a range of preventive, rehabilitation, palliative care and bereavement services in the community.

Social implications

To combine knowledge about individuals held in the community to align the respective inputs, and expectations about outcomes while considering networked pathways based on functional status, above diagnostic pathways, and along a life-continuum.

Originality/value

The hub as a whole seems to (1) Enhance engagement through relationship, trust and activation, (2) Exchanging knowledge to co-create a shared bio-psycho-social understanding of each individual’s situation and goals, (3) Personalising care planning by utilising the range of available resources to ensure needs are met, and (4) Enhancing co-ordination and ongoing care through multi-disciplinary working between practitioners, across teams and sectors.
