The Pre-Pottery Neolithic A (PPNA) period in Southwest Asia is essential for our understanding of the transition to sedentary, agricultural communities. Developments in architecture are key to understanding this transition, but many aspects of PPNA architecture remain elusive, such as construction techniques, the selection of building materials, and the functional use of space. The primary aim of the research described within this contribution was to build a PPNA-like structure in order to answer questions about PPNA architecture in general, while specifically addressing issues raised by the excavation of structures at the site of WF16, Southern Jordan. The second aim was to display a ‘PPNA’ building to visitors in Wadi Faynan to enhance their understanding of the period. The experimental construction based on one of the WF16 structures showed that 1) required materials can be acquired locally; 2) a construction technique using mud layers as described in this paper was likely used; 3) flat, or very slightly dome-shaped, roofs are functional and can also be used as a solid working platform; 4) the WF16 small semi-subterranean buildings appear inappropriate for housing a nuclear family unit.

Neste texto é apresentado o relatório final do projeto 561/06, “Análise Econômica da Reforma Fiscal do PIS-COFINS: Integrando um modelo de micro-simulação com um Modelo de Equilíbrio Geral Computável”. Essencialmente trata-se de uma extensão metodológica do projeto 461/04, visando um aprimoramento da quantificação dos impactos sobre indicadores de bem estar, particularmente pobreza e desigualdade. Além do modelo de Equilíbrio Geral, busca-se uma integração com um modelo de micro-simulação, baseado nas pesquisas domiciliares com o intuito de aprofundar e identificar o impacto que a reforma fiscal teve sobre indivíduos e famílias brasileiras, fazendo com estes sejam identificados com uma precisão muito maior, na medida em que a pesquisa anterior permitia apenas a identificação de um agrupamento representativo da população brasileira, enquanto esta permite a integração no modelo das amostras individuais presentes na PNAD. Os resultados apresentados são sensíveis a nova metodologia utilizada.

Neste artigo é apresentada uma avaliação dos impacto da reforma tributária do PIS/PASEP e da COFINS, que passaram a ser coletados através de dois regimes associados aos fluxos domésticos (cumulativo e não cumulativo - misto) e a incidir sobre importações de bens e serviços. A metodologia adotada utiliza um modelo de Equilíbrio Geral Computável (CGE), adaptado para as novas características do sistema fiscal e especificado para simular os impactos sobre indicadores de bem-estar no Brasil. Estes impactos foram avaliados em duas etapas: a mudança do regime cumulativo para o novo regime tributário e a reforma completa. Os resultados mostram que esta reforma teria provocado deterioração dos indicadores macroeconômicos, de mercado de trabalho e de bem-estar.

Background The accumulation of mutations after long-lasting exposure to a failing combination antiretroviral therapy (cART) is problematic and severely reduces the options for further successful treatments. Methods We studied patients from the Swiss HIV Cohort Study who failed cART with nucleoside reverse transcriptase inhibitors (NRTIs) and either a ritonavir-boosted PI (PI/r) or a non-nucleoside reverse transcriptase inhibitor (NNRTI). The loss of genotypic activity <3, 3–6, >6 months after virological failure was analyzed with Stanford algorithm. Risk factors associated with early emergence of drug resistance mutations (<6 months after failure) were identified with multivariable logistic regression. Results Ninety-nine genotypic resistance tests from PI/r-treated and 129 from NNRTI-treated patients were analyzed. The risk of losing the activity of ≥1 NRTIs was lower among PI/r- compared to NNRTI-treated individuals <3, 3–6, and >6 months after failure: 8.8% vs. 38.2% (p = 0.009), 7.1% vs. 46.9% (p<0.001) and 18.9% vs. 60.9% (p<0.001). The percentages of patients who have lost PI/r activity were 2.9%, 3.6% and 5.4% <3, 3–6, >6 months after failure compared to 41.2%, 49.0% and 63.0% of those who have lost NNRTI activity (all p<0.001). The risk to accumulate an early NRTI mutation was strongly associated with NNRTI-containing cART (adjusted odds ratio: 13.3 (95% CI: 4.1–42.8), p<0.001). Conclusions The loss of activity of PIs and NRTIs was low among patients treated with PI/r, even after long-lasting exposure to a failing cART. Thus, more options remain for second-line therapy. This finding is potentially of high relevance, in particular for settings with poor or lacking virological monitoring.
