The Fitting Subgroup and Some Injectors of Radical Locally Finite Groups with min-pfor Allp

2003

Abstract This work was intended as an attempt to continue the study of the class ℬ of generalised nilpotent groups started in a previous paper. We present some results concerning the Fitting subgroup and the ℬ-injectors of a radical locally finite group satisfying min-p for all p.

A Gaschütz–Lubeseder Type Theorem in a Class of Locally Finite Groups

1999

The aim of this paper is to present a Gaschutz–Lubeseder type theorem in the class cL of all radical locally finite groups satisfying min−p for all primes p. Notice that these groups are countable and co-Hopfian by [1, (5.4.8)]. In retrospect, the theory of saturated formations of finite soluble groups began with the results of Gaschutz [3] in 1963. He introduced the concept of “covering subgroup” as a generalization of Sylow and Hall subgroups. These covering subgroups have many of the properties of Sylow and Hall subgroups other than the arithmetic ones. The main idea of Gaschutz’s work was concerned with group theoretical classes having the same properties. He defined a formation F to be…

On some classes of supersoluble groups

2007

[EN] Finite groups G for which for every subgroup H and for all primes q dividing the index |G:H| there exists a subgroup K of G such that H is contained in K and |K:H|=q are called Y-groups. Groups in which subnormal subgroups permute with all Sylow subgroups are called PST-groups. In this paper a local version of the Y-property leading to a local characterisation of Y-groups, from which the classical characterisation emerges, is introduced. The relationship between PST-groups and Y-groups is also analysed.

Variational parabolic capacity

2015

We establish a variational parabolic capacity in a context of degenerate parabolic equations of $p$-Laplace type, and show that this capacity is equivalent to the nonlinear parabolic capacity. As an application, we estimate the capacities of several explicit sets.

Geofanie. La Terra postmoderna

2015

L’altro ieri qualcosa è cambiato e noi non ce ne siamo accorti. La Terra, che credevamo stabilizzata in un’immagine razionale, che sapevamo parto laborioso di un lungo transito dal mito alla scienza, ha cominciato a pulsare e a deformarsi di nuovo. Per tentativi, per assaggi periferici, qualcuno ha provato a reinventarla, trovando nelle sue forme in rilievo una spinta molto antica e molto attuale. Questa tettonica dell’immaginario viaggiava su assi precisi: epica, cosmografia, corpo come misura del mondo. La Terra postmoderna, perché è di questo che si tratta, era molto più di una vaga intuizione e molto meno di paradigma condiviso. Questo libro è la ricognizione di un’alba già finita, è la…

Sferracavallo. Un villaggio per i santi

Geographic imagination and urban-rural binary in online discourses related to the capital region of Finland : A corpus onomastic study of Helsinki, V…

2023

The article focuses on digital discourses related to Helsinki, Espoo and Vantaa, the three biggest municipalities in Finland’s capital region. The data consist of texts from the discussion forum of Suomi24 that was analysed to find out how forum users produce socio-spatial distinctions by categorizing some groups as ‘others’ thus differentiating in-groups and out-groups. The analysis used methods of comprised corpus assisted discourse studies (CADS), including collocation analysis. The results show that discourses related both to native and non-native Helsinkians and to those living in the capital region in contrast to those living elsewhere in Finland are common and the juxtapositions betw…

Dipinto su tavola “Tre Sante Martiri”: il restauro conservativo di un supporto ligneo gravemente danneggiato

2020

Il poster descrive l'intervento conservativo svolto su un dipinto su tavola raffigurante “Tre Sante Martiri”, secondo il consolidato principio di un approccio multidisciplinare tecnico e scientifico. Il manufatto, realizzato con la tecnica ad olio e risalente al XVII secolo, è di proprietà del Comune di Cefalù (PA), pervenuto a seguito di lascito testamentario da parte di un nobile collezionista dell’Ottocento, l’avvocato Vincenzo Cirincione, ed è conservato presso il locale Museo intitolato ad “Enrico Piraino barone di Mandralisca”. La prima parte dell’intervento ha riguardato lo studio degli aspetti storico-artistici, dei materiali e delle tecniche esecutive, degli interventi pregressi di…

Achieving agreement on service needs in child protection : Comparing children’s, mothers’ and practitioners’ views over time and between approaches

2022

Purpose While studies on service users’ participation and their perceptions on the quality of services exist, agreement between family members’ and practitioners’ assessments of the family’s situation has received less interest. The purpose of this paper is to investigate agreement and its effect on outcomes by comparing the viewpoints of three groups of informants (children, mothers and practitioners) in the context of statutory child protection in two study groups – one applying a systemic approach (SPM) and a service-as-usual control group (SAU). Design/methodology/approach A quasi-experimental repeated-measures study design was applied. Outcome data comprised 112 cases (SPM cases n = 5…

Breslau. Nazwa miasta jako dziedzictwo kulturowe — zarys problematyki w perspektywie analizy dyskursu historycznego

2020

W artykule śledzę taktyki przywoływania (i unikania) wcześniejszych nazw współczesnego Wrocławia jako elementu tworzenia jego dziedzictwa kulturowego. Na przykładzie opracowań historycznych i wykorzystując metodę analizy dyskursu, pokazuję mechanizmy kreowania różnie akcentowanych przeszłości miasta. Opierając się na użyciu nazwy historycznej (na przykład Breslau) czy konsekwentnie tylko współczesnej (Wrocław), wskazuję, że za strategią wyboru nazwy stoją odmienne, ideologicznie uwarunkowane, narracje. Jedni badacze, używając wcześniejszych, historycznych nazw miasta, tworzą obraz ciągle zmieniającego się europejskiego ośrodka miejskiego, natomiast drudzy, posługując się wyłącznie współczes…
