The relevance of corporate social responsibility for a sustainable human resource management: An analysis of organizational attractiveness as a deter…

2012

Corporate Social Responsibility (CSR) has become a central issue of business management in recent years. This study aims to add to the literature by pointing out the relevance of CSR for a Sustainable Human Resource Management (HRM). In particular this research investigates job seekers’ perceptions of CSR. The paper focuses on the importance of CSR with in the process of selecting potential employers by analyzing the impact of four different CSR-dimensions upon organizational attractiveness. To address this issue, a policy-capturing study was conducted. Generally the paper provides evidence that each aspect of CSR has a specific effect on organizational attraction. Referring to Sustainable …

Fundamental frequency of the female's voice: A cross-country empirical study on its influence on social and sexual selection

2020

Recent studies demonstrate that voice (in particular, its fundamental frequency -Fo-) may influence on social and sexual selection. Here, we tested how the Fo of female's voice is related to different aspects of social and sexual selection through a novel experimental approach. First, we recorded and measured the Fo of 22 women reading a neutral text in Spanish language. Six of these voices were selected and classified into three categories: voices with a low Fo (225 Hz). Then, these voices were rated by two independent samples including both men and women: one comprised of native Spanish-speakers (n = 683) and the other comprised of native Italian non-Spanish-speakers (n = 484). Contrarily…

A case-control evaluation of sensory profile among preschool children affected by autism spectrum disorder

2019

Background: Autism spectrum disorders (ASD) are neurobehavioral syndromes caused by a developmental disorder, biologically determined, with a very early onset and deficit mainly related to social communication and interaction.There is a considerable amount of literature on ASD suggesting abnormal sensory experience as a basic symptom, as also reported by the DSM-5 and ICD-10.The current case-control study aimed to investigate the sensory perception skills in preschool children affected by ASD compared with a control group of typical developing children.Materials and methods: The study sample was composed of 42 children, subdivided into two groups: 21 ASD (12 males); 21 typical developing (T…

Metal-support and preparation influence on the structural and electronic properties of gold catalysts

2006

Abstract Nanostructured gold catalysts supported on CeO2 and SiO2 were prepared by the deposition–precipitation (DP) and the solvated metal atom dispersion (SMAD) techniques. The structural and electronic properties of the catalysts were investigated by X-ray diffraction (XRD), X-ray absorption spectroscopy (XAS) and X-ray photoelectron spectroscopy (XPS). Gold was found as small metal nanoparticles (cluster size ∼2 nm) in the SMAD-prepared samples and in ionic state in the DP catalysts. The catalytic activity of the samples was tested in the reaction of low temperature CO oxidation. Gold nanosized particles in a pure metallic state exhibited a worse catalytic performance, both on ceria and…

Fully automatic face recognition system using a combined audio-visual approach

2005

This paper presents a novel audio and video information fusion approach that greatly improves automatic recognition of people in video sequences. To that end, audio and video information is first used independently to obtain confidence values that indicate the likelihood that a specific person appears in a video shot. Finally, a post-classifier is applied to fuse audio and visual confidence values. The system has been tested on several news sequences and the results indicate that a significant improvement in the recognition rate can be achieved when both modalities are used together.

Visuo-auditory sensory substitution systems are augmented reality devices that translate a video stream into an audio stream in order to help the blind in daily tasks requiring visuo-spatial information. In this work, we present both a new mobile device and a transcoding method specifically designed to sonify moving objects. Frame differencing is used to extract spatial features from the video stream and two-dimensional spatial information is converted into audio cues using pitch, interaural time difference and interaural level difference. Using numerical methods, we attempt to reconstruct visuo-spatial information based on audio signals generated from various video stimuli. We show that de…

Steered Response Power Localization of Acoustic Passband Signals

2017

The vast majority of localization approaches using phase transform (PHAT) consider that the sources of interest are wideband low-pass sources. While this may be the usual case for common audio signals such as speech, PHAT methods are affected negatively by modulation artifacts when the sources to be localized are passband signals. In these cases, steered response power PHAT localization becomes less robust. This letter analyzes the form of generalized cross-correlation functions with PHAT when passband acoustic signals are considered, proposing approaches for increasing the localization performance through the mitigation of these negative effects.

On the Design of Probe Signals in Wireless Acoustic Sensor Networks Self-Positioning Algorithms

2018

A wireless acoustic sensor network comprises a distributed group of devices equipped with audio transducers. Typically, these devices can interoperate with each other using wireless links and perform collaborative audio signal processing. Ranging and self-positioning of the network nodes are examples of tasks that can be carried out collaboratively using acoustic signals. However, the environmental conditions can distort the emitted signals and complicate the ranging process. In this context, the selection of proper acoustic signals can facilitate the attainment of this goal and improve the localization accuracy. This letter deals with the design and evaluation of acoustic probe signals all…
