Collective Intentionality, Language, and Normativity: A Problem and a Possible Solution for the Analysis of Cooperation
2015
In this paper I discuss Searle's analysis of social ontology in the light of his account of the sources of normativity as rooted in the logical structure of language. I conclude that, though his theory of normativity may appear to be inconsistent with his theory collective intentionality, it is really our Background sense of the other that creates a sense of community even before the actual functioning of collective intentionality and language, thereby escaping the dilemma between individualism and collectivism.
The role of peer groups in adolescents' educational trajectories
2009
The present study investigated whether the members of adolescents' peer groups show similar educational trajectories from comprehensive school to either senior secondary or vocational education, and to what extent their educational expectations, academic achievement, family structure, and parents' SES predict these trajectories. Five hundred thirty adolescents filled in a questionnaire focusing on their educational expectations, academic achievement and family background variables before the transition to post-comprehensive education. They were also asked to nominate three peers with whom they most liked to spend their time. After the transition, they reported the school form they were in. …
A video-based real-time vehicle counting system using adaptive background method
2008
International audience; This paper presents a video-based solution for real time vehicle detection and counting system, using a surveillance camera mounted on a relatively high place to acquire the traffic video stream.The two main methods applied in this system are: the adaptive background estimation and the Gaussian shadow elimination. The former allows a robust moving detection especially in complex scenes. The latter is based on color space HSV, which is able to deal with different size and intensity shadows. After these two operations, it obtains an image with moving vehicle extracted, and then operation counting is effected by a method called virtual detector.
Interobserver and intraobserver variability in the radiological assessment of sialolithiasis using cone beam computed tomography
2021
Background Data regarding the inter- and intraobserver variability in the radiological assessment of sialolithiasis using cone beam computed tomography are missing in the current literature. This study assessed the inter- and intraobserver variability in the radiological assessment of sialolithiasis using cone beam computed tomography (CBCT). Material and Methods In 107 patients, 130 salivary glands (65 parotid and 65 submandibular) with clinical signs of obstruction were assessed by four independent observers; 2 residents OMFS and 2 experienced OMFS. The observers analyzed the CBCT images and determined the absence or presence of one or more salivary stones in the affected gland. This proc…
No evidence of systematic pre-emptive loggings after notifying landowners of their lands’ conservation potential
2020
Landowners can intentionally impair biodiversity values occurring on their land to pre-empt biodiversity protection. This often leads to significant negative effects on biodiversity. We studied whether landowners in Finland engaged in pre-emptive loggings after they were notified that their wooded mires are candidate sites for a mire protection program. After the notification, harvesting rates of the candidate wooded mires were significantly lower compared to harvesting rates of similar but non-candidate wooded mires. Annual and monthly harvesting rates indicated that notifying landowners of the conservation potential did not launch systematic pre-emptive logging behavior. Nevertheless, par…

Objectives: Energy drink consumption among adolescents has become a notable global phenomenon, and has been associated with numerous negative health outcomes. In order to understand the popularity of energy drinks among adolescents, and to target interventions, it is important to identify the determinants underpinning consumption.Methods: The nationally representative data (cross-sectional) were drawn from the Health Behaviour in School-aged Children (HBSC) surveys, conducted in 2014 and 2018, each comprising 13- and 15-year-old Finnish adolescents (n = 7405).Results: Weekly energy drink consumption increased among Finnish adolescents between 2014 (18.2%) and 2018 (24.4%), especially among …
Towards a Non-Intrusive Context-Aware Speech Quality Model
2020
Understanding how humans judge perceived speech quality while interacting through Voice over Internet Protocol (VoIP) applications in real-time is essential to build a robust and accurate speech quality prediction model. Speech quality is degraded in the presence of background noise reducing the Quality of Experience (QoE). Speech Enhancement (SE) algorithms can improve speech quality in noisy environments. The publicly available NOIZEUS speech corpus contains speech in environmental background noise babble, car, street, and train at two Signal-to-noise ratio (SNRs) 5dB and 10dB. Objective Speech Quality Metrics (OSQM) are used to monitor and measure speech quality for VoIP applications. Th…
Ethnicity and Educational Inequality: An investigation of School Experience in Australia and France. Ethnicité et inégalité scolaire : une enquête su…
2008
This thesis examines the contribution of ‘ethnic' background to the school experiences of educationally and socially disadvantaged students in the senior years of high school (n=927). To investigate the role both of ethnic identification and its interplay with institutional factors, a comparative analysis of secondary student experiences in two national settings was undertaken. The case of Turkish-background students in Australia and France suggests that the influences of ethnic identity are thoroughly transformed from one setting to the other by distinctive pedagogical structures. Streaming and severe academic judgement in France lower academic self-esteem, while creating resentment and so…
Non-circular rotating beams and CMB experiments
2002
This paper is concerned with small angular scale experiments for the observation of cosmic microwave background anisotropies. In the absence of beam, the effects of partial coverage and pixelisation are disentangled and analyzed (using simulations). Then, appropriate maps involving the CMB signal plus the synchrotron and dust emissions from the Milky Way are simulated, and an asymmetric beam --which turns following different strategies-- is used to smooth the simulated maps. An associated circular beam is defined to estimate the deviations in the angular power spectrum produced by beam asymmetry without rotation and, afterwards, the deviations due to beam rotation are calculated. For a cert…
Beam deconvolution in noisy CMB maps
2003
The subject of this paper is beam deconvolution in small angular scale CMB experiments. The beam effect is reversed using the Jacobi iterative method, which was designed to solved systems of algebraic linear equations. The beam is a non circular one which moves according to the observational strategy. A certain realistic level of Gaussian instrumental noise is assumed. The method applies to small scale CMB experiments in general (cases A and B), but we have put particular attention on Planck mission at 100 GHz (cases C and D). In cases B and D, where noise is present, deconvolution allows to correct the main beam distortion effect and recover the initial angular power spectrum up to the end…
