Abstract
Electrical machines are more and more fed by static converters. These power supplies impose nonsinusoidal statoric waveform to the machines. In these conditions, behaviour of magnetic material can be very different compared with sinusoidal ones. The characterization of magnetic material under non‐sinusoidal excitations is not clearly defined. At the present time, there is not any standard about operating test and specific parameters to be measured in order to get efficient knowledge of soft magnetic materials in distorted excitation mode. The aim of this paper is to present the effect of statoric connections on harmonic characterization parameters. The experimental results correspond to a Fe‐Si non oriented material excited by two different waveforms in a classical Epstein frame. The behaviour of the material is divided into two parts: the fundamental and the harmonic responses. The fundamental parameters are representative of the duty frequency of the machine, harmonic ones give information about additional losses; especially their harmonic distribution. They also allow us to estimate harmonic impact on the fundamental response.

Abstract
Purpose
This paper aims to propose a new strategic foresight process that combines aspects from science fiction, speculative design and tools linked to organizational processes, first, to generate potential new services and products and, second, to reduce problems associated with the construction of low-impact and irrelevant scenarios for decision-making processes. As a new proposal, it invites reflection and debate.
Design/methodology/approach
After reviewing the literature on the key concepts that represent the essence of strategic foresight, as well as the traditional processes to reflect on the future, a proposal for a new hybrid, integrative foresight process that allows moving from imagination to the materialization of scenarios will be presented.
Findings
The new hybrid process makes evident the need to articulate strategic foresight with other areas of knowledge and management tools to build scenarios with greater impact on decision-making and greater added value from strategic foresight to organizational processes.
Originality/value
The proposed integrative model articulates tools that already exist, but the originality of the proposal lies in that there are no models that integrate science fiction, speculative design, and other organizational tools in a single process.

Abstract
Examines the types and characteristics of the new forms of the brand management system in marketing organizations as identified in previous research and previous existing research on performance appraisal systems. Draws linkages between the two systems to provide a framework for maximizing individual product manager’s performance, thereby maximizing overall organizational performance. Sets out a number of managerial implications and suggests areas for future research.
