This paper aims to present the principle of virtual air gap inductance and the design of a voltage regulation device based on this principle. The authors provide a comprehensive analysis of this specific application that consists of locally saturating the magnetic circuit of the voltage regulator to modify its global properties. This saturation is created by a direct current flowing in a small auxiliary coil inserted in the specific area of the magnetic circuit to saturate this zone.

Analytical calculation and finite elements simulations are used to optimize the device for a specific application tied to the supply of electrical ovens in metallurgic usage. Experimental results are presented at the end of the paper.

The experimental results presented in this paper are in concordance with the analytical calculation and with the finite element simulations for different operation points. The difficulty of the study of the virtual air gap comes mainly from the nonlinearity of the phenomena because the principle is based on a local and controllable saturation of the magnetic circuit.

The originality of the paper concerns the introduction of virtual air gap principle in a specific industrial application.

In many countries, service workers' (e.g. restaurant staff, bartenders) income depends highly on tips. Such workers are often female and targeted by sexual harassment. The purpose of this paper was to investigate whether the mode of compensation (tips vs. no tips) could play a causal role in the perceived legitimacy of sexual harassment.

In an experimental study (N = 161), the authors manipulated the source of income of a fictional female bartender (fixed income vs. smaller fixed income + tips) as well as whether she or her boss chose her (sexualized) clothing. The authors then asked male participants in an online survey to imagine being her customer and to form an impression of her.

The bartender was viewed as more sexualized, more manipulative and sexual behaviors toward her were perceived as more legitimate when she received tips. Further, the effect of tipping on the legitimacy of sexual behaviors was mediated by perceptions that she was manipulative. The target was perceived as more manipulative when she chose her clothes than not.

The study is an online scenario study and, as a consequence, assesses only judgments rather than actual behaviors.

Encouraging fixed salaries rather than tipping could reduce the occurrence of sexual harassment.

The present work suggests that tipping may play a detrimental role in service workers' well-being by contributing to an environment in which sexual harassment is perceived as legitimate.

To the authors’ knowledge, this is the first study showing that mode of compensation can increase the objectification of workers and legitimize sexually objectifying behaviors toward them.

Undoubtedly, Fortran dominates the field of scientific computing from commercial packages to university programs. Although Pascal and C have managed to seduce some programmers with their newer design, the majority of users still favours Fortran into which most of those new features are eventually incorporated. The innovative programming tools offered by new languages have not been able to justify the time and cost required for the training of programmers and the porting of existent code.

Shareholders, investors and potential employees, all attach special importance to understanding a company through its annual report, the status of which has evolved over the years: from providing information for the adepts of competitive intelligence, it now provides information available to all stakeholders in the company. But one aspect has not changed: the keynote message of the president that prefaces the annual report. The present article indicates current practice in the matter in the case of 28 leading French companies.

We have made these companies the subject of a systematic and detailed computer‐assisted analysis.

Among the main conclusions to be noted are: a varied range of rhetorical cosmetics by way of embellishment, and attitudes either of prudence or optimism on the part of company heads; a type of discourse open to several levels of interpretation: from a literal level to a level allowing the reader to interpret the wider spirit and intention of the document.

In view of the time devoted to the preparation and fine‐tuning of a presidential letter, we feel justified in writing a modest letter of recommendations for the attention of the president at the end of this contribution.

This research explores two interconnected questions: (1) How do we approach stylistic features of multimodal rhetorical artifacts such as protest posters? (2) Do said artifacts designed for different purposes exhibit systematic stylistic differences? Drawing on Charles Sanders Peirce’s semiotic categorization, this study develops a framework for examining concision, one of the primary stylistic considerations for multimodal rhetorical artifacts such as protest posters. This paper illustrates the use of this framework by exploring the correlation between rhetorical purpose and concision in posters created and disseminated before and during the 2011–2012 Québécois student movement. This study fine-tunes our existing knowledge on multimodality with style sensitivity, and demonstrates how an economy-of-sign based semiotic approach could enrich the empirical examination of multimodal rhetorical artifacts by generating more controlled interpretations.
