On prefix normal words and prefix normal forms
2016
A $1$-prefix normal word is a binary word with the property that no factor has more $1$s than the prefix of the same length; a $0$-prefix normal word is defined analogously. These words arise in the context of indexed binary jumbled pattern matching, where the aim is to decide whether a word has a factor with a given number of $1$s and $0$s (a given Parikh vector). Each binary word has an associated set of Parikh vectors of the factors of the word. Using prefix normal words, we provide a characterization of the equivalence class of binary words having the same set of Parikh vectors of their factors. We prove that the language of prefix normal words is not context-free and is strictly contai…
Atteindre l'éducation pour tous en 2015 est-il un objectif réalisable ?
2004
This paper is looking at the feasibility of achieving the objective of education for all, one of the millennium objectives set up by the international community for the year 2015. Among numerous obstacles on the road map, the author is focusing on the budgetary constraint, which has aggravated significantly during the past decade. Actually the gap between least advanced countries and the rest of the world is widening, and not narrowing. Two remedies are proposed by the donor community for assisting the least developed countries to fill the gap : first a more efficient utilisation of resources presently allocated to education, and it seems that the efficiency reforms which are proposed are o…
The distributional effects of capital account liberalization
2018
Abstract Episodes of account liberalization increase the Gini measure of inequality, based on panel data estimates for 149 countries from 1970 to 2010. These episodes are also associated with a persistent increase in the share of income going to the top. We investigate three channels through which these impacts could occur. First, the impact of liberalization on inequality is stronger where credit markets lack depth and financial inclusion is low; positive impacts of liberalization on poverty rates also vanish when financial inclusion is low. Second, the impact on inequality is also stronger when liberalization is followed by a financial crisis. Third, liberalization seems to alter the rela…
Poincaré inequalities and Steiner symmetrization
1996
A complete geometric characterization for a general Steiner symmetric domain Ω ⊂ Rn to satisfy the Poincare inequality with exponent p > n−1 is obtained and it is shown that this range of exponents is best possible. In the case where the Steiner symmetric domain is determined by revolving the graph of a Lipschitz continuous function, it is shown that the preceding characterization works for all p > 1 and furthermore for such domains a geometric characterization for a more general Sobolev–Poincare inequality to hold is given. Although the operation of Steiner symmetrization need not always preserve a Poincare inequality, a general class of domains is given for which Poincare inequalities are…
Atypical perceptual narrowing in prematurely born infants is associated with compromised language acquisition at 2 years of age
2010
Abstract Background Early auditory experiences are a prerequisite for speech and language acquisition. In healthy children, phoneme discrimination abilities improve for native and degrade for unfamiliar, socially irrelevant phoneme contrasts between 6 and 12 months of age as the brain tunes itself to, and specializes in the native spoken language. This process is known as perceptual narrowing, and has been found to predict normal native language acquisition. Prematurely born infants are known to be at an elevated risk for later language problems, but it remains unclear whether these problems relate to early perceptual narrowing. To address this question, we investigated early neurophysiolog…
Learning from Differences
2018
This paper presents a case study of an intensive international course aimed at pre-service teachers and having a focus on inclusion. The course was funded by Nordplus. Twenty-three students from six Baltic and Nordic countries were interviewed during and after the course on their views on professionalism and their future work as teachers. The results show that the students’ understanding of professionalism was multifaceted, and they had gained several experiences of professionalism during the course. One of the main results of this study is, in our opinion, the co-operation and the opportunities the intensive course afforded the students in developing skills to work together with different …
On the Kneser property for reaction–diffusion equations in some unbounded domains with an -valued non-autonomous forcing term
2012
Abstract In this paper, we prove the Kneser property for a reaction–diffusion equation on an unbounded domain satisfying the Poincare inequality with an external force taking values in the space H − 1 . Using this property of solutions we check also the connectedness of the associated global pullback attractor. We study also similar properties for systems of reaction–diffusion equations in which the domain is the whole R N . Finally, the results are applied to a generalized logistic equation.
On the validity of Friedrichs’ inequalities
1984
A standard proof of Friedrich's second inequality is based on contradiction argumentation. In this paper a direct proof is presented. Moreover, necessary and sufficient conditions for the validity of Friedrichs' first and second inequality are given for plane domains. peerReviewed
The ALHAMBRA survey: reliable morphological catalogue of 22 051 early- and late-type galaxies
2013
Advanced Large Homogeneous Area Medium Band Redshift Astronomical (ALHAMBRA) is photometric survey designed to trace the cosmic evolution and cosmic variance. It covers a large area of ~4 deg2 in eight fields, where seven fields overlap with other surveys, allowing us to have complementary data in other wavelengths. All observations were carried out in 20 continuous, medium band (30 nm width) optical and 3 near-infrared (JHK) bands, providing the precise measurements of photometric redshifts. In addition, morphological classification of galaxies is crucial for any kind of galaxy formation and cosmic evolution studies, providing the information about star formation histories, their environme…
Challenging Unequal Gendered Conventions in Heterosexual Relationship Contexts through Affective Dissonance
2019
In Nordic countries, intimate relationships are routinely compared against ideals of gender equality, even though equality is not always achieved in everyday life. In this article, we analyse interviews with women that lived in unconventional relationships: mid- to later-life women in relationships with younger men, and bisexual women who have had relationships with people of different genders. The women’s expectations of equality and reciprocity in heterosexual relationships collided with the lived reality of inequalities, causing affective dissonance. We identify three strategies that women use to deal with this affective dissonance. In the first strategy, unequal relationship patterns ar…
