Perfect Hashing Structures for Parallel Similarity Searches
2015
International audience; Seed-based heuristics have proved to be efficient for studying similarity between genetic databases with billions of base pairs. This paper focuses on algorithms and data structures for the filtering phase in seed-based heuristics, with an emphasis on efficient parallel GPU/manycores implementa- tion. We propose a 2-stage index structure which is based on neighborhood indexing and perfect hashing techniques. This structure performs a filtering phase over the neighborhood regions around the seeds in constant time and avoid as much as possible random memory accesses and branch divergences. Moreover, it fits particularly well on parallel SIMD processors, because it requ…
The parental bond, resistance to peer influence and risky driving in adolescence
2014
The present study examined the relations between gender, the parental bond, resistance to peer influence, and risky driving. In particular, the mediating role of resistance to peer pressure in the relationship between parental bond and risky driving was examined. The moderating role of gender on these associations was also investigated. The sample comprised 322 adolescents (136 males and 186 females), aged from 16 to 20 years, who were living in northern Italy. Path analysis results showed that the maternal bond only indirectly influenced adolescents’ risky driving, via resistance to peer influence. On the contrary, the paternal bond was neither directly nor indirectly associated with risky…
Accompagnement de fin de vie en néonatologie : forums de discussion, reconnaissance de la parentalité et savoirs d'expérience
2019
International audience; Ce chapitre aborde la situation de poursuite de grossesse malgré un diagnostic anténatal défavorable à la vie du bébé. Certains parents ayant fait le choix d'un accompagnement de fin de vie se rendent sur des forums de discussion en ligne aussi bien pour partager leurs ressentis que pour compléter et mettre en perspective les informations fournies par les équipes soignantes. Le partage d'expériences dans le cadre de ce dispositif numérique participe à l'élaboration d'une double expertise, de nature relationnelle et biomédicale. La première a trait à la construction de la parentalité dans un contexte où les remises en cause de ce statut sont nombreuses. La deuxième se…
From estate representation to the representation of the people and the nation in the Age of Revolutions
2020
In the Age of Revolutions, the legitimacy of political rule was increasingly derived in Western countries from popular sovereignty realised through parliamentary representation. This chapter analyses how the members of the representative institutions in Britain, France and Sweden attempted to solve tensions between popular sovereignty and representation during a revolutionary or evolutionary transition from the early modern representation of the interests of estates by delegates to the representation of the people by individual members. We also consider the American, Dutch and German assemblies and transnational interaction between political cultures. Tensions between the concepts of repres…
Measuring the perceived value of rural tourism: a field survey in the western Sicilian agritourism sector
2016
Rural tourism constitutes a valuable tool for the sustainable development of many rural areas. This paper examines the concept of perceived value in rural tourism. A quantitative field survey was carried out in some main Western Sicilian holiday farms (agritourisms) during the Spring 2014. A theoretical model of the tourists’ perceived value in this specific context was developed and validated, using a 22-item scale. Using Partial Least Squares Path Modelling a theoretical structural model of the multidimensional structure of the RTPV was tested, assessing intensity and direction of the causal relationships among RTPV and its dimensions. Five dimensions were identified as forming the constr…
Structural Parameters under Partial Least Squares and Covariance-Based Structural Equation Modeling : A Comment on Yuan and Deng (2021)
2023
In their article, Yuan and Deng argue that a structural parameter under partial least squares structural equation modeling (PLS-SEM) is zero if and only if the same structural parameter is zero under covariance-based structural equation modeling (CB-SEM). Yuan and Deng then conclude that statistical tests on individual structural parameters assessing the null hypothesis of no effect can achieve the same purpose in CB-SEM and PLS-SEM. Our response to their article highlights that the relationship they find between PLS-SEM and CB-SEM structural parameters is not universally valid, and that consequently, tests on individual parameters in CB-SEM and PLS-SEM generally do not fulfill the same pur…
Ion beam intensity and phase space measurement techniques for ion sources.
2022
Ion sources produce beams used in accelerators and other applications. Both development and use of ion sources need beam diagnostics to probe the plasma processes and beam formation for optimization purposes and to produce beam parameters needed for transport tuning. These diagnostics include beam intensity measurements usually carried out with Faraday cups or inductive pickups, magnetic separation, profile measurements with scintillation screens and wires, and phase space measurements with different types of emittance scanners. peerReviewed
Partnership formation and dissolution over the life course: applying sequence analysis and event history analysis in the study of recurrent events
2015
We present two types of approach to the analysis of recurrent events for discretely measured data, and show how these methods can complement each other when analysing co-residential partnership histories. Sequence analysis is a descriptive tool that gives an overall picture of the data and helps to find typical and atypical patterns in histories. Event history analysis is used to make conclusions about the effects of covariates on the timing and duration of the partnerships. As a substantive question, we studied how family background and childhood socio-emotional characteristics were related to later partnership formation and stability in a Finnish cohort born in 1959. We found that high se…
Non esse parua sine quibus magna constare non possunt: la pequeña grandeza de la gramática según Antonio de Nebrija (y Erasmo)
