Pais, « child » and « slave »
No full textLe mot grec pais signifie communément « enfant » et « esclave ». C'est l'histoire du mot qui nous apprend l'origine de cette double signification : l'enfant et l'esclave appartenaient tous deux au rang social subordonné. La caractérisation de l'esclave comme « enfantin » aux points, de vue intellectuel et moral est un développement postérieur du mot. La sujétion des enfants et des esclaves est marquée tout particulièrement par l'abus physique. Cet abus se reflète dans plusieurs textes littéraires où figurent des jeux de mots sur pais et paiein ( = « battre » quelqu'un).Golden Mark. Pais, « child » and « slave ».

On the masses and evolutionary status of the black hole binary GX 339-4: a twin system of XTE J1550-564?
No full textWe apply the K-correction to the black hole low-mass X-ray binary (LMXB) GX 339-4 which implies MX? 6 M? by only assuming that the companion is more massive than ?0.17 M?, the lower limit allowed by applying a ‘stripped-giant’ model. This evolutionary model successfully reproduces the observed properties of the system. We obtain a maximum mass for the companion of M2? 1.1 M? and an upper limit to the mass ratio of q(=M2/MX) ? 0.125. The high X-ray activity displayed by the source suggests a relatively large mass transfer rate which, according to the model, results in M2? 0.3 M? and MX? 7 M?. We have also applied this scenario to the black hole binary XTE J1550-564, which has a similar orbital period but the donor is detected spectroscopically. The model successfully reproduces the observed stellar parameter
Business social network services (BSNSs): uno strumento per superare le discriminazioni professionali legate all’età?
No full textA partire dagli studi di Mark Granovetter dei primi anni Settanta,
si è sviluppato un ampio filone di studi relativo all’impatto della configurazione strutturale dei
network relazionali sul successo professionale degli individui e sulla competitività delle
organizzazioni.
Negli ultimi anni, stanno emergendo piattaforme internet esplicitamente finalizzate alla costruzione
di legami deboli per scopi professionali: i business social network online.
Tra questi, il più rilevante per accessi è LinkedIn. In Italia, nel 2005 è nato Milan IN,
un’associazione no profit che offre agli utenti di LinkedIn che vivono o lavorano a Milano la
possibilità di incontrarsi di persona e che oggi conta oltre 5.300 membri.
Il saggio presenta i risultati di un’indagine condotta attraverso questionario online, somministrato
all’universo dei soci Milan IN.
Attraverso l’analisi delle corrispondenze multiple, sono stati delineati dei profili “generazionali”
d’approccio al business social networking online (LinkedIn) e in presenza (Milan IN). La realizzazione di interviste
semi-strutturate a soci Milan IN ha permesso di approfondire i risultati emersi dal questionario e di
analizzare anche i profili statisticamente poco significativi, ma sociologicamente rilevanti, dei soci
under 25 e over 70

An alternative Hamiltonian formulation for the Pais–Uhlenbeck oscillator
No full textAbstractOstrogradsky's method allows one to construct Hamiltonian formulation for a higher derivative system. An application of this approach to the Pais–Uhlenbeck oscillator yields the Hamiltonian which is unbounded from below. This leads to the ghost problem in quantum theory. In order to avoid this nasty feature, the technique previously developed in [7] is used to construct an alternative Hamiltonian formulation for the multidimensional Pais–Uhlenbeck oscillator of arbitrary even order with distinct frequencies of oscillation. This construction is also generalized to the case of an N=2 supersymmetric Pais–Uhlenbeck oscillator
The odd-order Pais–Uhlenbeck oscillator
No full textAbstractWe consider a Hamiltonian formulation of the (2n+1)-order generalization of the Pais–Uhlenbeck oscillator with distinct frequencies of oscillation. This system is invariant under time translations. However, the corresponding Noether integral of motion is unbounded from below and can be presented as a direct sum of 2n one-dimensional harmonic oscillators with an alternating sign. If this integral of motion plays a role of a Hamiltonian, a quantum theory of the Pais–Uhlenbeck oscillator faces a ghost problem. We construct an alternative canonical formulation for the system under study to avoid this nasty feature

Reuniões de pais e mestres : um meio para a participação dos pais na escola
No full textOrientador: Profa. Clara Brener MindalMonografia (graduação) - Universidade Federal do Paraná, Setor de Educação, Curso de Graduação em PedagogiaInclui referências : p. 59-60Resumo : O presente Trabalho de Conclusão de Curso com o tema "Reuniões de pais e mestres: um meio para a participação dos pais na escola", traz em seu conteúdo elementos presentes na literatura sobre a relação família e escola; a análise de um questionário feito com sete professores dos anos iniciais do ensino fundamental e a diretora da escola e o relato da observação de uma reunião de pais que aconteceu com uma turma de 3o ano do ensino fundamental em uma escola municipal de Curitiba. A partir dessas investigações buscou-se conhecer como os professores veem a presença dos pais na escola, como a escola convida os pais para irem às reuniões, como funcionam as reuniões e o que atrai os pais até elas, além de identificar algumas características da interação entre família e escola. Por encontrar pouca referência específica ao tema reunião de pais, tratou-se da interação escola família (investigações como as de Bhering, Chapadeiro e Lima e Polonia e Dessen e a Lei de Diretrizes e Bases da Educação Nacional de 1996), que é um tema amplo e muito pesquisado e focalizou-se dentro da relação família escola o assunto sobre reuniões de pais e mestres na escolaAbstract : The present Work of Conclusion of Course with the theme "Parent-Teacher Meetings: A Means for Parent Involvement in School", brings in its content elements present in the literature on family and school relationship; the analysis of a questionnaire applicated to seven teachers and school’s principal at initial years of elementary school, and the report of the observation of a parents' meeting that happened to a class of 3rd year of elementary school in a municipal school in Curitiba. From these investigations, we knew how the teachers understand the presence of the parents in the school, how the school invites the parents to go to the meetings, how the meetings works and what attracts the parents to the school, besides identifying some characteristics of the interaction between family and school. By finding little specific reference to the theme parent meeting, it was the family school interaction (Author investigations like Bhering, Chapadeiro & Lima and Polonia & Dessen and "Lei de Diretrizes e Bases da Educação Nacional de 1996" : LDB policy of 1996), which is a broad and well researched topic and focused within the family-school relationship the subject about parent-teacher meetings at school
