On almost nilpotent varieties of subexponential growth
2015
Abstract Let N 2 be the variety of left-nilpotent algebras of index two, that is the variety of algebras satisfying the identity x ( y z ) ≡ 0 . We introduce two new varieties, denoted by V sym and V alt , contained in the variety N 2 and we prove that V sym and V alt are the only two varieties almost nilpotent of subexponential growth.
Characterizing varieties of colength ≤4
2009
Let A be an associative algebra over a field F of characteristic zero, and let χ n (A), n = 1,2,…, be the sequence of cocharacters of A. For every n ≥ 1, let l n (A) denote the nth colength of A, counting the number of S n -irreducibles appearing in χ n (A). In this article, we classify the algebras A such that the sequence of colengths l n (A), n = 1,2,…, is bounded by four. Moreover we construct a finite number of algebras A 1,…, A d , such that l n (A) ≤ 4 if and only if A 1,…, A d ∉ var(A).
Varieties of superalgebras of almost polynomial growth
2011
Abstract Let V gr be a variety of superalgebras and let c n gr ( V gr ) , n = 1 , 2 , … , be its sequence of graded codimensions. Such a sequence is polynomially bounded if and only if V gr does not contain a list of five superalgebras consisting of a commutative superalgebra, the infinite dimensional Grassmann algebra and the algebra of 2 × 2 upper triangular matrices with trivial and natural Z 2 -gradings. In this paper we completely classify all subvarieties of the varieties generated by these five superalgebras, by giving a complete list of finite dimensional generating superalgebras.
Proper identities, Lie identities and exponential codimension growth
2008
Abstract The exponent exp ( A ) of a PI-algebra A in characteristic zero is an integer and measures the exponential rate of growth of the sequence of codimensions of A [A. Giambruno, M. Zaicev, On codimension growth of finitely generated associative algebras, Adv. Math. 140 (1998) 145–155; A. Giambruno, M. Zaicev, Exponential codimension growth of P.I. algebras: An exact estimate, Adv. Math. 142 (1999) 221–243]. In this paper we study the exponential rate of growth of the sequences of proper codimensions and Lie codimensions of an associative PI-algebra. We prove that the corresponding proper exponent exists for all PI-algebras, except for some algebras of exponent two strictly related to t…
Identity dynamics and social partitions : the case of identity "racial" Blacks in France
2011
Our research work investigates - from a psycho-social point of view - the «racial» identity of the black population in France, notably in their relation with the white population, so as to point up the identity dynamics that exist between the various groups. The theoretical framework is related to social grouping and one of its developments, i.e. the concept of social partitioning. Such conception is based on the existence of several types of inter-category relations (partitioning) that allow apprehending the nature of individuals’ identity positioning within the framework of an inter-group relation and make it dynamic through the notion of co-construction. Our methodology is based mainly o…
El discurso totalitario del partido político España 2000
2016
Este artículo analiza los elementos principales del discurso del partido político español, España 2000, concebida como una formación adscrita a la corriente de «derecha radical populista». Para ello, se emplea la metodología de análisis de contenido y se aplica el modelo de «Totalismo Ideológico» propuesto por Robert Jay Lifton, que describe los elementos que caracterizan a las ideologías radicales. Como fuentes de información se utilizan las declaraciones de los líderes de la formación durante un conflicto sucedido en la ciudad de Valencia (España). La investigación muestra las particularidades totalitarias del discurso de la formación española y sus principales ejes ideológicos, que al ig…
The Double-Deviant Identity of the Mass-Foreigner and the Lack of Authority of the Crimmigrationist State
2019
Crimmigration has its breeding ground in dystopian and securitarian narratives. The anti-hero of these narratives is the mass-foreigner, a stereotyped version of the foreigner usually depicted, alternatively or cumulatively, as an enemy or as a parasite of host societies. But not only does crimmigration presuppose such narratives (and the deviant identity of the mass-foreigner, which is connected with them) as a source of legitimation, it also fuels these same narratives by providing them with an official sanction: by merging criminalization and irregularization on a legal level, it heavily contributes to making the social identity of mass-foreigners into a doubly deviant one. The overarchi…

"[English] is a part of who I am" : investigating English majors' linguistic identities
2016
Vaikka monikielisyys ei olekaan uusi ilmiö, on siitä esimerkiksi kehittyvän teknologian ja kansainvälisen liikkuvuuden kautta tullut yhä näkyvämpi osa nykypäivän maailmaa. Englannin leviäminen ympäri maailmaa on yksi osa tätä kehitystä, ja esimerkiksi Suomessa englanti on erityisen tärkeässä osassa kansainvälisen kommunikoinnin kielenä. Erityisen tärkeä monikielisyyden ja englannin rooli on suomalaisten yliopisto-opiskelijoiden elämässä, jotka opiskelevat pääaineenaan englantia. Monikielisyyden vaikutuksista puhuttaessa on tärkeää ottaa huomioon myös identiteetti, koska nykypäivän kielitieteellisessä tutkimuksessa katsotaan kielen ja identiteetin suhteen olevan erittäin vankka. Tämän tutkim…
Finnish model of peer-group mentoring: review of research.
2019
This article reviews research on the Finnish model of peer‐group mentoring (PGM). The theoretical foundation of the model is based on the constructivist theory of learning, the concept of autonomy in teaching profession, peer learning, and narrative identity work. The model has been disseminated nationwide in the educational sector to promote professional development of teachers and educational staff, mainly in primary and secondary education, but also in early childhood education and higher education. The thematic review is based on 46 peer‐reviewed publications about PGM in Finland in 2009–2019. Research has focused on the following main themes: (1) general aspects and characteristics of …
