Moves like Jagger - multidimensional attractiveness ratings of opposite-sex dancers

2012

Research has shown that a number of factors, including body symmetry, perceived strenght, vigour, skilfulness, and agility of movements, as well as increased variability and amplitude of the neck and trunk, can affect the attractiveness of dance moves. Perceived femininity/masculinity of body movement likely also plays a role. Here, we compare comprehensive ratings of both male and female dancers' opposite-sex attractiveness, including ratings of femininity/masculinity, with computationally-extracted movement features. Sixty-two heterosexual adult participant watched 48 short audio-visual point-light animations of eight male and eight female adult participants dancing individually to Techno…

All Eyes on Me : Behaving as Soloist in Duo Performances Leads to Increased Body Movements and Attracts Observers’ Visual Attention

2020

Duo musicians exhibit a broad variety of bodily gestures, but it is unclear how soloists’ and accompanists’ movements differ and to what extent they attract observers’ visual attention. In Experiment 1, seven musical duos’ body movements were tracked while they performed two pieces in two different conditions. In a congruent condition, soloist and accompanist behaved according to their expected musical roles; in an incongruent condition, the soloist behaved as accompanist and vice versa. Results revealed that behaving as soloist, regardless of the condition, led to more, smoother, and faster head and shoulder movements over a larger area than behaving as accompanist. Moreover, accompanists …

Luminescence properties of neodymium-doped yttrium aluminium garnet obtained by the co-precipitation method combined with the mechanical process

2005

Nanopowders of yttrium aluminium garnet Y3Al5O12 (YAG) doped with neodymium ions were obtained by the co-precipitation method from the reaction of aluminium and yttrium nitrate and neodymium oxide with ammonia. After washing and drying the hydroxide precursors were calcined at 500, 700, 800 and 900 °C for 1 hour and at 1000 °C for 3 hours. This product was treated by ball milling in a zirconia vial for 0.5, 1.5 and 10 h in order to achieve smaller nanoparticles. The structure, microstructure, morphology and optical properties were investigated by means of diffractometric, microscopic and spectroscopic techniques. The course of the amorphous-to-crystalline transformation was complete after c…

Preparation of Nd:YAG Nanopowder in a Confined Environment

2007

Nanopowder of yttrium aluminum garnet (YAG, Y3Al5O12) doped with neodymium ions (Nd:YAG) was prepared in the water/cetyltrimethylammonium bromide/1-butanol/n-heptane system. Aluminum, yttrium, and neodymium nitrates were used as starting materials, and ammonia was used as a precipitating agent. Coprecipitate hydroxide precursors where thermally treated at 900 degrees C to achieve the garnet phase. The starting system with and without reactants was characterized by means of the small-angle neutron scattering technique. The system, without reactants, is constituted by a bicontinuous structure laying near the borderline with the lamellar phase region. The introduction of nitrates stabilizes th…

Second Harmonic Emission From Dielectric Nanoresonators in the Absorption Regime

2023

We study second harmonic generation in dielectric nanocylinders as a function of the wavelength of the incident field and geometrical dimensions. Uncommonly, we consider a spectral range in which the emitted nonlinear signal is partially absorbed by the dielectric. Surprisingly, we reveal that the second harmonic efficiency does not decrease as the imaginary part of the complex dielectric refractive index increases. Indeed, the presence of higher order multipoles supported by the resonators at the fundamental wavelength can significantly boost the generated second harmonic signal even in the dielectric absorption spectral region achieving nonlinear efficiency of the same order of magnitude …

Explanations of success and failure in management learning : What can we learn from Nokia's rise and fall

2016

International audience; In this paper, we study the changing explanations of success and failure over the course of a firm's history. We build on a discursive approach that highlights the role of narrative attributions in making sense of corporate performance. Specifically, we analyze how the Nokia Corporation was framed first as a success and later as a failure and how these dimensions of performance were explained in various actors' narrative accounts. In both the success and failure accounts, our analysis revealed a striking black-and-white picture that resulted in the institutionalization of Nokia's metanarratives of success and failure. Our findings also reveal a number of discursive a…

Technical and economical comparison between NdFeB and hard ferrites linear electrical generators from sea waves

2015

In this paper the authors perform a technical-economic comparison of two different Tubular Permanent Magnet Linear Machines for sea waves generation by using finite elements analysis. The first configuration includes ferrite rings while the second configuration includes neodymium-iron-boron rings. In order to compare the two types in economic and technical terms, a detailed analysis of the main figures of merit of the two configurations has been carried out. In particular, significant data such as flux distribution, rated voltage and current, axial force, electric power, realization cost and maintenance cost have been compared.
