Contradiction between the average age of retirement at the time of death and the average pension time for men and women in public employment in Portugal

The short article attempts to make some very brief reflections on the effects a lack of public policies positively discriminatory in terms of public employment retirement. In particular, the observation of the absurd contradiction between the average age of retirement at the time of death (for men and women) and the average pension time for men and women in public employment in Portugal.

O fenómeno da desorçamentação: breves considerações à nomenclatura

0 presente artigo analisa o sentido e alcance da nomenclatura desorçamentação. Trata-se de um neologismo recentemente usado na literatura das ciências económicas, e em especial nas finanças públicas, que tem gerado alguma controvérsia, resultando dali interpretações e visões muitas vezes dissemelhantes para o mesmo fenómeno. Embora o conceito não tenha tradução para outras línguas procurou-se fazer uma aproximação à sua semelhança terminológica em termos do seu signifi­cado. O contexto e, em especial, o Orçamento de Estado.

A nova gestão pública e a reforma administrativa

O presente artigo analisa os efeitos do custo, da grandeza e da comple­xidade que o sector público alcançou com o desenvolvimento do Estado de Bem-Estar social e que levou a que um conjunto de países industrializados procedesse a realização de mudanças, mais ou menos radicais, nas estruturas e nas funções do Estado e, em particular; na Administração Pública, pela adopção de novas ideias de gestão, oriundas do sector privado, paradigma conhecido na literatura com a designação de New Public Management.

Os diferentes níveis de regulação legal dos conflitos de interesses no âmbito da gestão de fundos de investimento mobiliário

In the context of the activity developed by securities investment funds (hereinafter referred to “SIF”) the holders of investment units have a very tiny power to intervene. Aware of the risks that a decoupling between ownership and control may pose, the legislator has foreseen a number of impositions and limitations to the activity of the managing entities, namely to prevent or prohibit the performance of acts in situations of potential conflicts of interests. Accordingly, the purpose of the dissertation on – “Os diferentes níveis de regulação legal dos conflitos de interesses no âmbito da gestão de FIM” – is exactly to determine the field of application of the several levels of legal regulation of the conflicts of interests that arise within the scope of the management of SIF, both at the level of the new legal requirements governing collective investment undertakings, and at the level of the legal requirements governing the conflicts of interests foreseen in the Portuguese Securities Code, in order to clarify the articulation of these different levels of conflicts of interests regulations.

REDESCRIPTION OF APOSTOLEPIS LONGICAUDATA (SERPENTES: XENODONTINAE) WITH COMMENTS ON ITS HEMIPENIAL MORPHOLOGY AND NATURAL HISTORY

Apresentamos a redescricao da rara especie de serpent Apostolepis longicaudata Comes in Amaral coin base no exame do holotipo e em comparacoes com tres novos exemplares do Cerrado do Brasil Central. O trabalho inclui dados ineditos sobre a coloracao em vida, morfologia hemipeniana e historia natural. Dois especimes lineados previamente identificados como A. quinquelineata por outros autores sao redeterminados aqui como A. nelsonjorgei, que parece ser a unica especie do genero cujas contagens de subcaudais se sobrepoem as de A. longicaudata.

A new species of the lizard genus Bachia (Squamata : Gymnophthalmidae) from the Cerrados of Central Brazil

A new species of Bachia of the bresslaui group, is described from Estacao Ecologica Serra Geral do Tocantins, a recently created protected area in the Central Brazilian Cerrados of state of Tocantins. The new species is most similar to Bachia psamophila from which it differs in limb morphology and head and body scalation. As in Bachia psamophila the shovel-shaped snout of the new species is highly prominent, an adaptation related to its psamophilous habits.

TAXONOMY OF THE SOUTH AMERICAN DWARF BOAS OF THE GENUS TROPIDOPHIS BIBRON, 1840, WITH THE DESCRIPTION OF TWO NEW SPECIES FROM THE ATLANTIC FOREST (SERPENTES: TROPIDOPHIIDAE)

A taxonomic study on the South American dwarf boas of the genus Tropidophis revealed the existence of two new species in the Atlantic Forest bionic. As a result, we recognize five mainland species, three in the Atlantic Forest and two in northwestern South America. Based on general distribution and morphological orientation, the type locality of T. paucisquamis is restricted to Estacao Biologica de Boraceia (EBB), municipality of Salesopolis, state of Sao Paulo, Brazil; furthermore, a lectotype for T. taczanowskyi is designated. We provide data on the hemipenial morphology of two South American Tropidophis, showing that the quadrifurcate condition described for West Indian taxa also occurs in mainland congeners. The distributions of the three Atlantic Forest species are congruent with patterns of diversification of other vertebrate taxa associated with cold climates prevalent at high elevations. Refugial isolation and riverine barriers may account for such speciation events.

Cryptic species in Iphisa elegans Gray, 1851 (Squamata: Gymnophthalmidae) revealed by hemipenial morphology and molecular data

Iphisa elegans Gray, 1851 is a ground-dwelling lizard widespread over Amazonia that displays a broadly conserved external morphology over its range. This wide geographical distribution and conservation of body form contrasts with the expected poor dispersal ability of the species, the tumultuous past of Amazonia, and the previously documented prevalence of cryptic species in widespread terrestrial organisms in this region. Here we investigate this homogeneity by examining hemipenial morphology and conducting phylogenetic analyses of mitochondrial (CYTB) and nuclear (C-MOS) DNA sequence data from 49 individuals sampled across Amazonia. We detected remarkable variation in hemipenial morphology within this species, with multiple cases of sympatric occurrence of distinct hemipenial morphotypes. Phylogenetic analyses revealed highly divergent lineages corroborating the patterns suggested by the hemipenial morphotypes, including co-occurrence of different lineages. The degrees of genetic and morphological distinctness, as well as instances of sympatry among mtDNA lineages/morphotypes without nuDNA allele sharing, suggest that I. elegans is a complex of cryptic species. An extensive and integrative taxonomic revision of the I. elegans complex throughout its wide geographical range is needed.

Taxonomy, Hemipenial Morphology, and Natural History of Two Poorly Known Species of Anadia (Gymnophthalmidae) from Northern South America

Anadia pariaensis Rivas, La Marca, and Oliveros, 1999, and Anadia steyeri Nieden, 1914, are two particularly rare and poorly known lizards described from single specimens. In the case of A. pariaensis, it remains known from the holotype, whereas A. steyeri is known from three additional specimens reported in the literature after the original description of the species. A single new specimen of A. pariaensis and five of A. steyeri, including the first adult males recorded for both species, make possible a more representative description of both species, including descriptions of the hemipenes. Despite both species presenting some similar morphological characteristics, the examination of the hemipenial morphology revealed very different organs. The hemipenis of A. steyeri presents some characteristics that resemble the organs of two species from the Santa Marta Mountain Range in the "bitaeniata-group" (Anadia pulchella and Anadia altaserrania). On the other hand, the hemipenes of A. pariaensis are unique morphologically and cannot be associated with the hemipenes known from other species in the genus. We describe variation within both species, and we comment on possible sexual dimorphism (number and arrangement of the femoral pores), natural history, and the known geographic distribution of the species. We also comment on Anadia bumanguesa Rueda-Almonacid and Caicedo 2004 based on a new specimen, the second known. This species may be a synonym of A. steyeri.

OS TELEJORNAIS E A ERA DIGITAL: UM ESTUDO SOBRE AS TRANSFORMAÇÕES NO TRABALHO E NA CONSTRUÇÃO DAS NOTÍCIAS EM EMISSORAS REGIONAIS DO VALE DO PARAÍBA

Este trabalho dedica-se a examinar as principais mudanças que ocorrem no processo de construção da notícia nos telejornais regionais paulistas na última década. Objetivamos o estudo das tecnologias digitais conectadas e as consequentes alterações no trabalho dos profissionais envolvidos jornalistas, técnicos e engenheiros, a fim de entender os novos formatos aplicados na transmissão de conteúdo contando com o auxílio da internet. Para tanto, realizamos um estudo comparativo com duas emissoras da Região Metropolitana do Vale do Paraíba: TV Vanguarda, afiliada a Rede Globo, e a Tv Band Vale filiada ao Grupo Bandeirantes, que passaram por transformações em todas as dimensões da difusão de notícias com a digitalização dos seus processos tecnológicos e investimentos no ambiente virtual. Por meio da técnica de pesquisa observação participante chegou-se a conclusão de que a tecnologia é uma realidade adotada nas emissoras contribuindo para agilizar os trabalhos nas redações e aproximar o público dos telejornais.
