TRADITION AND CHANGE IN POPULAR CLASSES’S FAMILIES

As famílias das classes populares, na cidade de São Paulo, têm sido vitimadas pelas condições adversas de sobrevivência na cidade, uma vez que são, quase todas, de origem migrante. Sofrem, ainda, dois processos simultâneos de segregação e desqualificação. Este artigo discute, brevemente, as noções de tradição e mudança vividas pelas famílias das classes populares urbanas, enfatizando as diferenças culturais e a necessidade de adaptação aos desafios que o meio urbano propõe. Esses desafios estão presentes nas transformações dos padrões de autoridade masculina e na construção de novas modalidades de vida familiar.This paper deals with the changing familiar life of migrants in São Paulo’s city. In the urban environment they suffer two simultaneous processes:segregation and disqualification. We discuss, briefly, tradition and change, experienced by the urban popular classes’s families, proposing cultural differences as a partial explanation for the difficult task of adjustment. This adjustment refers more specifically to changes in the patterns of authority which affects the family and to the different ways ofdealing with them altering family organization

The Child and the Adolescent Statute: Is it Possible to Become a Psychological Reality?

O artigo descreve as barreiras à aplicação efetiva de uma legislação avançada, como o Estatuto da Criança e do Adolescente, quanto às suas disposições sobre a família, a escola e o trabalho. Defende, ainda, maior participação dos cursos universitários no conhecimento e respeito à lei, favorecendo sua aplicação no cotidiano profissional.The article describes the effective application of an advanced legislation, as the Child and Adolescent Statute, considering the family, school and work issues. It also defends a broader involvement of the university courses with the statute acquaintance and enforcement, favoring its aplication on the professional routine

Multi-messenger observations of a binary neutron star merger

On 2017 August 17 a binary neutron star coalescence candidate (later designated GW170817) with merger time 12:41:04 UTC was observed through gravitational waves by the Advanced LIGO and Advanced Virgo detectors. The Fermi Gamma-ray Burst Monitor independently detected a gamma-ray burst (GRB 170817A) with a time delay of ~1.7 s with respect to the merger time. From the gravitational-wave signal, the source was initially localized to a sky region of 31 deg2 at a luminosity distance of 40+8-8 Mpc and with component masses consistent with neutron stars. The component masses were later measured to be in the range 0.86 to 2.26 Mo. An extensive observing campaign was launched across the electromagnetic spectrum leading to the discovery of a bright optical transient (SSS17a, now with the IAU identification of AT 2017gfo) in NGC 4993 (at ~40 Mpc) less than 11 hours after the merger by the One- Meter, Two Hemisphere (1M2H) team using the 1 m Swope Telescope. The optical transient was independently detected by multiple teams within an hour. Subsequent observations targeted the object and its environment. Early ultraviolet observations revealed a blue transient that faded within 48 hours. Optical and infrared observations showed a redward evolution over ~10 days. Following early non-detections, X-ray and radio emission were discovered at the transient’s position ~9 and ~16 days, respectively, after the merger. Both the X-ray and radio emission likely arise from a physical process that is distinct from the one that generates the UV/optical/near-infrared emission. No ultra-high-energy gamma-rays and no neutrino candidates consistent with the source were found in follow-up searches. These observations support the hypothesis that GW170817 was produced by the merger of two neutron stars in NGC4993 followed by a short gamma-ray burst (GRB 170817A) and a kilonova/macronova powered by the radioactive decay of r-process nuclei synthesized in the ejecta
