The purpose of this paper is to exploit the optimal performances of each magnetic material in terms of low iron losses and high saturation flux density to improve the efficiency and the power density of the selected motor.

This paper presents a study to improve the power density and efficiency of e-motors for electric traction applications with high operating speed. The studied machine is a yokeless-stator axial flux permanent magnet synchronous motor with a dual rotor. The methodology consists in using different magnetic materials for an optimal design of the stator and rotor magnetic circuits to improve the motor performance. The candidate magnetic materials, adapted to the constraints of e-mobility, are made of thin laminations of Si-Fe nonoriented grain electrical steel, Si-Fe grain-oriented electrical steel (GOES) and iron-cobalt Permendur electrical steel (Co-Fe).

The mixed GOES-Co-Fe structure allows to reach 10 kW/kg in rated power density and a high efficiency in city driving conditions. This structure allows to make the powertrain less energy consuming in the battery electric vehicles and to reduce CO₂ emissions in hybrid electric vehicles.

The originality of this study lies in the improvement of both power density and efficiency of the electric motor in automotive application by using different magnetic materials through a multiobjective optimization.

Making effective use of the knowledge available to a charitable organization is crucial to the achievement of its strategic objectives and the outcomes of its humanitarian interventions. This study aims to explore the integration of knowledge at an international development charity from the perspective of its workforce.

Rich primary data were collected through an in-depth case study of a large international development charity actively embracing the management of knowledge using semi-structured interviews (n = 42), participant observation and organizational documentation. The data were integrated and analyzed thematically.

The analysis of the empirical data sheds light on how a more systematic framework for knowledge integration and application could enhance the capabilities and strategic effectiveness of a charitable organization.

The findings enable important contributions to the strategic management and effective use of knowledge in charitable organizations by empirically uncovering how a more coherent and structured approach to knowledge management could enhance the focus, efficiency, flexibility and relevance of its actions and those of its members. Accordingly, this paper advances a new integrated schema to meet the goals of charities and their stakeholders for broader application and testing by charities and future researchers.

This chapter attempts to offer a clearer look at the historical roots of the founding of mutualist finance. Without denying that the various forms of financial mutualism may have legal and organizational roots in ancient times, the author considers what, for contemporary mutualist banks, may constitute the soul.

In its first part, the document presents the individual constructions that existed in the eighteenth and nineteenth centuries, in a context in which economic development and the industrial revolution banished the rules and standards of the former society. It refers to Utopian socialisms as opposed to the scientific solutions proposed for a new social organization and to the new solidarism according to Léon Bourgeois. Christian sources are also called to mind with social Christianity (Protestant) and social Catholicism until the birth of the social doctrine of the Church.

This frenzy of ideas as well as the confrontation with reality led to the birth, in Germany, of the first experiments with alternative finance. This is the subject of the second part of this chapter, which then develops the bank mutualism created by the founding fathers, F.W. Raiffeisen and H. Schulze-Delitzsch.

The historical description of the creation of mutualist banks brings up two major problems when talking about the “other finance”: the interest and activity of the bank. Is an ethical finance capable of proposing a credible alternative? This is a question that needs to be answered in the light of history.

This chapter attempts, more than 150 years after the fact, to demonstrate the ponderous presence of the question and the permanence of the founding ideas in order to comprehend the facts and propose ideas for analysis and construction of an “other finance.”

To address challenges such as inadequate funding and inefficiency in public infrastructure construction, PPPs have gained significant global traction. This study aims to comprehensively assess the impacts and mechanisms of PPPs on the SDI and to provide rational policy recommendations based on the findings.

We collated a dataset from 30 Chinese provinces covering the years 2005–2020 as our research sample. The study’s hypotheses are tested using a double fixed-effects model, a chained mediated-effects model and a multidimensional heterogeneity analysis.

Our findings indicate that PPPs have a facilitating effect on SDI in general. This boost usually lags behind policy implementation and is cyclical in the time dimension. In the spatial dimension, PPPs contribute significantly to SDI in the eastern and western regions, but not in the central region. From the perspective of the dynamics of economic, social and industrial development, PPPs in economically backward areas are difficult to promote SDI, promote it the most in economically medium regions and are slightly less in economically developed regions than in medium regions. This promotion effect has an inverted U-shaped relationship with social development and diminishes with industrial structure upgrading. Finally, due to the negative relationship between PPPs and social development and between social development and SDI, PPPs are shown to contribute to SDI and are identified as critical paths. However, PPPs suppress SDI by inhibiting economic and industrial development.

This study makes three novel contributions to the existing body of knowledge: (1) we innovatively introduce the United Nations Sustainable Development Goals (SDGs) into the field of infrastructure research, offering fresh perspectives on SDI enhancement; (2) revealing the mechanisms by which PPPs affect SDI through the three dimensions of economic, social and industrial development enabling policymakers to better understand and optimize resource allocation and improve planning, design and management of PPP projects for sustainable infrastructure and (3) we assess the spatiotemporal variances of PPPs’ effects on SDI and the diversity across regions at different social, economic and industrial structures developmental stages, offering critical insights to global decision-makers to devise tailored policy measures.
