Time allocation during Higher education : a study of Brazilian, French and Spanish students
1995
International audience; The results we present enable us to highlight common features and disparities in the way students from the three countries organize their time. While the lecture attendance time varies little from one country to another, it is different for other elements of time use. The Spaniards in particular seem to spend more time on personal work and the Brazilians more often have paid employment. The initial comparison should however be regarded as provisional in that no systematic correlation was made with educational policies in each country. Certainly, the lack of grants system in Brazil is linked to the significant amount of available time spent on salaried work but it wou…
Impact of repeating somatic cues on the depth of experiencing for withdrawers and pursuers in emotionally focused couple therapy
2021
Emotionally Focused Couple Therapy, an experiential modality, views emotion central to therapeutic change. In this exploratory study, we examined therapists' repetition of somatically focused interventions (therapist verbalizing somatic cues, such as facial expressions) and their impact on clients' emotional experiencing in-session. We also assessed difference for withdrawing versus pursuing partners. The sample included 13 EFT therapists who worked with one couple each for a single session. From transcripts we coded therapists' repetition of somatically focused interventions and clients' depth of experiencing pre-and post-intervention. Multilevel modeling demonstrated that a higher number …
Application of the Morris method for screening the influential parameters of fuzzy controllers applied to wastewater treatment plants
2011
In this paper,we evaluate the application of a sensitivity analysis to help fine-tuning a fuzzy controller for a biological nitrogen and phosphorus removal (BNPR) plant. TheMorris Screeningmethod is proposed and evaluated as a prior step to obtain the parameter significance ranking. First, an iterative procedure has been performed in order to find out the proper repetition number of the elementary effects (r) of the method. The optimal repetition number found in this study (r = 60) is in direct contrast to previous applications of the Morris method, which usually use low repetition number, e.g. r = 10 ~ 20. Working with a non-proper repetition number (r) could lead to Type I error (identify…
Algorithms for Computing Abelian Periods of Words
2012
Constantinescu and Ilie (Bulletin EATCS 89, 167--170, 2006) introduced the notion of an \emph{Abelian period} of a word. A word of length $n$ over an alphabet of size $\sigma$ can have $\Theta(n^{2})$ distinct Abelian periods. The Brute-Force algorithm computes all the Abelian periods of a word in time $O(n^2 \times \sigma)$ using $O(n \times \sigma)$ space. We present an off-line algorithm based on a $\sel$ function having the same worst-case theoretical complexity as the Brute-Force one, but outperforming it in practice. We then present on-line algorithms that also enable to compute all the Abelian periods of all the prefixes of $w$.
A note on easy and efficient computation of full abelian periods of a word
2016
Constantinescu and Ilie (Bulletin of the EATCS 89, 167-170, 2006) introduced the idea of an Abelian period with head and tail of a finite word. An Abelian period is called full if both the head and the tail are empty. We present a simple and easy-to-implement $O(n\log\log n)$-time algorithm for computing all the full Abelian periods of a word of length $n$ over a constant-size alphabet. Experiments show that our algorithm significantly outperforms the $O(n)$ algorithm proposed by Kociumaka et al. (Proc. of STACS, 245-256, 2013) for the same problem.
Primitive sets of words
2020
Given a (finite or infinite) subset $X$ of the free monoid $A^*$ over a finite alphabet $A$, the rank of $X$ is the minimal cardinality of a set $F$ such that $X \subseteq F^*$. We say that a submonoid $M$ generated by $k$ elements of $A^*$ is {\em $k$-maximal} if there does not exist another submonoid generated by at most $k$ words containing $M$. We call a set $X \subseteq A^*$ {\em primitive} if it is the basis of a $|X|$-maximal submonoid. This definition encompasses the notion of primitive word -- in fact, $\{w\}$ is a primitive set if and only if $w$ is a primitive word. By definition, for any set $X$, there exists a primitive set $Y$ such that $X \subseteq Y^*$. We therefore call $Y$…
Music, Architecture, Proportion and the Renaissance Way of Thinking
2020
During the Renaissance, the language of proportion became a unified theory capable of encompassing the understanding of the world within a coherent theological, philosophical and artistic framework. Music, with its harmonic paradigm, plays a key role in this construction. From the fifteenth century through to the end of the sixteenth century, architects and architectural theorists made reference, both in new treatises and commentaries to Vitruvius, to musical matters, transforming architecture into the summa of knowledge. The affinity to music was grounded on both a common mathematical and rhetoric gnosiology. Formerly conceived of as ideal, numbers became eloquent, reinforcing the quantita…
Repetition times for Gibbsian sources
1999
In this paper we consider the class of stochastic stationary sources induced by one-dimensional Gibbs states, with Holder continuous potentials. We show that the time elapsed before the source repeats its first n symbols, when suitably renormalized, converges in law either to a log-normal distribution or to a finite mixture of exponential random variables. In the first case we also prove a large deviation result.
Word assembly through minimal forbidden words
2006
AbstractWe give a linear-time algorithm to reconstruct a finite word w over a finite alphabet A of constant size starting from a finite set of factors of w verifying a suitable hypothesis. We use combinatorics techniques based on the minimal forbidden words, which have been introduced in previous papers. This improves a previous algorithm which worked under the assumption of stronger hypothesis.
Anglicisms and Italian Equivalents in the Era of Covid-19: A Corpus-Based Study of Lockdown
2020
The whole globe has been going through an unprecedented historical moment since World War II. COVID-19, the disease against which we have all been trying to defend ourselves for several months now, has spread worldwide with a significant impact in all spheres of life. With the pandemic outburst and English the language of globalization, several Anglicisms have entered the lexicon of other languages, especially Italian, traditionally open to foreign words. COVID-19-related Anglicisms are used in Italian to such an extent that we can reasonably refer to them as the ‘language of pandemic’. The English words and expressions employed in Italian to refer to the current disease are numerous. Some …
