La sovranità dell'Uno. Filosofia politica della grecità

2018

In this volume, Segreto traces the founding categories of political philosophy according to the greek ascendency. So Subject, community, sovereignty, politics represent a lexicon received by centuries and transformed itself by centuries. One is the red line that crosses classicity and modernity in our western political philosophy.

Servizio sociale internazionale, responsabilità locale e partecipazione comunitaria: un caso studio inTanzania.

2021

International social work is a field of professional practice that is widespread in various countries around the world, yet still little explored in the literature and little known as a specific field of action. Exploring its definition and its possible applications in practice, starting from the analysis of a social work case study within an international project, aims to encourage the consolidation of a flexible, inclusive and plural thinking and method, necessary both for social workers working abroad, or in international exchange projects, and for those working with foreign users, offering the opportunity to broaden horizons and at the same time to strengthen the roots of the profession.

Bill colour and immunocompetence in the European blackbird

2003

The level of expression of secondary sexual characters has been suggested to signal male ability to resist parasitic infestations. To test this idea, several studies have examined the link between sexual signals and immunocompetence in birds. However, most of them have used only a single aspect of immune response to evaluate immunocompetence. We investigated the relation between bill colour and immunocompetence in captive male European blackbirds, Turdus merula, during the breeding season by assessing both cell-mediated and humoral components of the immune system. The blackbird is a sexually dimorphic species with bill colour varying from yellow to orange in males. Humoral immunity was asse…

Prey community structure affects how predators select for Müllerian mimicry

2012

Müllerian mimicry describes the close resemblance between aposematic prey species; it is thought to be beneficial because sharing a warning signal decreases the mortality caused by sampling by inexperienced predators learning to avoid the signal. It has been hypothesized that selection for mimicry is strongest in multi-species prey communities where predators are more prone to misidentify the prey than in simple communities. In this study, wild great tits ( Parus major ) foraged from either simple (few prey appearances) or complex (several prey appearances) artificial prey communities where a specific model prey was always present. Owing to slower learning, the model did suffer higher mort…

Prehatching maternal investment and offspring immunity in the pied flycatcher (Ficedula hypoleuca).

2007

Maternal investment in offspring immunity via egg quality may be an adaptive evolutionary strategy shaped by natural selection. We investigated how maternal investment in eggs can influence offspring immunity by conducting two experiments. First, we manipulated foraging performance of the mothers before egg laying by attaching a small weight to their back feathers. During the nestling period, we investigated offspring total antibody production at the age of 7 days and after antibody challenge, and conducted a partial cross-fostering design to separate the effects of the experiment and rearing-related variation on offspring immunity. In a separate experiment, partial cross-fostering with ant…

Isolation of a novel LPS-induced component of the ML superfamily in Ciona intestinalis

2015

ML superfamily represents a group of proteins playing important roles in lipid metabolism and innate immune response. In this study, we report the identification of the first component of the ML superfamily in the invertebrate Ciona intestinalis by means of a subtractive hybridization strategy. Sequence homology and phylogenetic analysis showed that this protein forms a specific clade with vertebrate components of the Niemann-Pick type C2 protein and, for this reason, it has been named Ci-NPC2. The putative Ci-NPC2 is a 150 amino acids long protein with a short signal peptide, seven cysteine residues, three putative lipid binding site and a three-dimensional model showing a characteristic b…

Modelo comunitario de convivencia en educación primaria

2016

Las escuelas que son comunidades de aprendizaje trabajan por la superación de la violencia de género siguiendo la línea de socialización preventiva y desarrollando el modelo dialógico de resolución de conflictos. En este artículo, a través de la realización de un estudio de caso en un aula de segundo de primaria, identificamos algunas de las interacciones sociales que están contribuyendo a afrontar situaciones de violencia que ocurren en la escuela, así como transformar las relaciones entre el alumnado. Estas interacciones han sido reflexionadas en el marco de las tertulias literarias dialógicas. Su análisis ha puesto de relieve, como estrategias efectivas para la mejora de la convivencia e…

Smooth Feshbach map and operator-theoretic renormalization group methods

2003

Abstract A new variant of the isospectral Feshbach map defined on operators in Hilbert space is presented. It is constructed with the help of a smooth partition of unity, instead of projections, and is therefore called smooth Feshbach map . It is an effective tool in spectral and singular perturbation theory. As an illustration of its power, a novel operator-theoretic renormalization group method is described and applied to analyze a general class of Hamiltonians on Fock space. The main advantage of the new renormalization group method over its predecessors is its technical simplicity, which it owes to the use of the smooth Feshbach map.
