Documentation, profile descriptions and analytical results of loes profiles from Bavaria, southern Germany

This study investigates the landscape evolution and soil development in the loess area near Regensburg between approximately 6000-2000 yr BP (radiocarbon years), Eastern Bavaria. The focus is on the question how man and climate influenced landscape evolution and what their relative significance was. The theoretical background concerning the factors that controlled prehistoric soil erosion in Middle Europe is summarized with respect to rainfall intensity and distribution, pedogenesis, Pleistocene relief, and prehistoric farming. Colluvial deposits , flood loams, and soils were studied at ten different and representative sites that served as archives of their respective palaeoenvironments. Geomorphological, sedimentological, and pedological methods were applied. According to the findings presented here, there was a high asynchronity of landscape evolution in the investigation area, which was due to prehistoric land-use patterns. Prehistoric land use and settlement caused highly difIerenciated phases of morphodynamic activity and stability in time and space. These are documented at the single catenas ofeach site. In general, Pleistocene relief was substantially lowered. At the same time smaller landforms such as dells and minor asymmetric valleys filled up and strongly transformed. However, there were short phases at many sites, forming short lived linear erosion features ('Runsen'), resulting from exceptional rainfalls. These forms are results of single events without showing regional trends. Generally, the onset of the sedimentation of colluvial deposits took place much earlier (usually 3500 yr BP (radiocarbon) and younger) than the formation of flood loams. Thus, the deposition of flood loams in the Kleine Laaber river valley started mainly as a consequence of iron age farming only at around 2500 yr BP (radiocarbon). A cascade system explains the different ages of colluvial deposits and flood loams: as a result of prehistoric land use, dells and other minor Pleistocene landforms were filled with colluvial sediments. After the filling of these primary sediment traps , eroded material was transported into flood plains, thus forming flood loams. But at the moment we cannot quantify the extent ofprehistoric soil erosion in the investigation area. The three factors that controlled the prehistoric Iandscapc evolution in the Ioess area near Regensburg are as follows: 1. The transformation from a natural to a prehistoric cultural landscape was the most important factor: A landscape with stable relief was changed into a highly morphodynamic one with soil erosion as the dominant process of this change. 2. The sediment traps of the pre-anthropogenic relief determined where the material originated from soil erosion was deposited: either sedimentation took place on the slopes or the filled sediment traps of the slopes rendered flood loam formation possible. Climatic influence of any importance can only be documented as the result of land use in connection with singular and/or statistic events of heavy rainfalls. Without human impact, no significant change in the Holocene landscape would have been possible.

Aspecto tumoral da cisticercose intracraniana: abordagem cirúrgica

The cerebral cysticercosis can produce intracranial hypertension by inflammatory obstruction of the basal cysterns or by expansive lesion in the cerebral parenchima or ventricular cavities. In the latter and in tumor cases the clinical picture is very similar and only after surgery can the etiology be determined. We present 11 operated cases of intracranial cysticercosis which presented the clinical picture of an expansive lesion. There were 7 females and 4 males with ages between 4 and 65 years. Nine patients were admitted because of headache, vomiting and visual disturbances suggestive of intracranial hypertension. One patient was admited with lymphocytic meningitis and another with focal seizures following hemiparesis. Five patients presented focal signs and six edema of the papilla. Epileptic manifestations were present in 45.5% of the cases. A plain X-ray films of the skull failed to reveal calcificatons, however signs of chronic hypertension were present in three cases. The electroencephalogram showed slow focal waves in 8 patients The spinal fluid examination revealed lymphocytosis in 4 cases, increased protein content in another 4 and complement fixation for cysticercosis was positive in 2 cases. The expansive lesions were localized by angiograph and ventriculography. In these the location was temporal in 4, frontal in 3, parietal in 2, in the third ventricle in one and in the fourth ventricle in another. At surgery we removed a large cyst from the cerebral parenchyma in six cases. Around the cyst a thick glial reaction was present. In the other cases the cyst was small but fixed to the ventricular trigone and produced dilatation of the inferior horn of the lateral ventricle. In two cases we removed a solitary intraventricular cyst from the third and fourth ventricles. In the two children operated upon there were several small hard cysts involving the cerebral parenchyma which displayed intense gliosis. There were no postoperative complications.

The Knowledge and Use of the Balanced Scorecard in Portugal: Empirical Evidence of the 250 Largest Companies

Balanced Scorecard (BSC) is recognized, both in the academic and business world, as one of the most powerful strategic management accounting tools. Thus, we launched in October 2004 a questionnaire survey applied to the 250 largest Portuguese companies aiming at observing the knowledge, use, and companies’ characteristics which are adopting this management instrument. Despite the majority of the companies inquired recognize BSC more as a strategic management tool than a performance valuation system, the results show that there is still a reduced and recent utilization of BSC in Portugal. Similarly to other countries Portugal is still in the initial state of BSC utilization. Our work has shown that the companies that use more BSC belong mainly to the secondary sector of industry. Nevertheless, unlike other studies, we did not get empirical evidence on the influence of variables such as geographical localization, dimension and internationalization, in the use and knowledge of BSC in Portugal.

"Goa Jesuits: 250 Years Ago and Since"

A Companhia de Jesus foi extinta em Goa como em Portugal em 1759. A Companhia restaurada regressou à Goa somente em 1931 via Belgaum, no território vizinho de Goa, na Índia britânica. A primeira base em Goa foi o Seminário de Rachol, e a seguir a residência de Bom Jesus, a antiga casa professa. Ao contrário da antiga Companhia de Jesus a Companhia restaurada regressou à India a partir de França. Era pró-Propaganda Fide e pouco favorável aos interesses políticos do Estado português da Índia. O que ajudou foi a abertura da Companhia restaurada para receber candidatos nativos goeses, o que não acontecera com a Companhia antes da extinção.

Alocação e mitigação dos riscos em parcerias público-privadas no Brasil

O objetivo da pesquisa foi efetuar levantamento das condições referentes à distribuição de risco nas formalizações das parcerias público-privadas no Brasil, a partir do marco legal que instituiu tal forma de implantação de equipamentos sociais no Brasil. Foram avaliados, por pesquisa documental, como os fatores de riscos estão sendo alocados e distribuídos em 15 contratos celebrados, buscando determinar como são mitigados os riscos inerentes entre os parceiros públicos e privados. Os contratos apresentam definição expressiva dos riscos envolvidos e de sua responsabilidade pelos parceiros. As evidências sinalizaram que os parceiros privados têm absorvido, formalmente, a maioria dos fatores de riscos elencados; contudo, há expressas medidas de mitigação dos riscos atribuídos nos contratos ao parceiro privado, pela intervenção em última instância do ente público envolvido.

Análise de políticas públicas: entre a modelagem e a realidade da política habitacional brasileira

Os desafios observados na implementação de políticas públicas têm fomentado uma série de debates no Brasil, entre os quais se destacam aqueles relacionados aos modelos teóricos de policy analysis e seus limites em face da visão multicêntrica e fractal das políticas públicas. Partindo de uma política setorial específica (habitacional), este artigo defende um posicionamento crítico em relação aos estudos monodisciplinares. Contudo, não se pode negar a complexidade dessa empreitada. Compreender os avanços da política habitacional da última década de forma interdisciplinar e integrada constitui uma tarefa intricada e desafiadora. Buscando avançar nesse campo, este artigo tem por objetivos avaliar os modelos teóricos de análise de políticas públicas e, a partir desses elementos, propor constructos com vistas a subsidiar futuros modelos teóricos de análise da política habitacional no Brasil.

Instrumentos e mecanismos de gestão: contribuições ao processo decisório em conselhos de políticas públicas

A administração pública no Brasil conta com diretrizes e parâmetros estabelecidos em documentos, a exemplo de leis, políticas ou planos, que se constituem em instrumentos para nortear e qualificar a gestão democrática das políticas públicas. A investigação buscou identificar instrumentos e mecanismos de gestão utilizados no processo decisório pelos Conselhos Municipais de Assistência Social e de Saúde em Chapecó (SC). A partir da leitura de atas (2005 a 2009), obtiveram-se como instrumento mais citado os relatórios de prestação de contas, embora esses não evidenciarem articulação com objetivos e metas definidos no plano municipal. Os mecanismos mais utilizados são comissões internas, capacitação, conferências e comunicação com outras organizações. Os conselhos estudados recorrem a instrumentos e mecanismos com potencial para ampliar a participação na gestão pública municipal.

OBJETIVO: Realizar a tradução, adaptação e validação de conteúdo da versão brasileira do Posttraumatic Cognitions Inventory . MÉTODOS: O processo de tradução e adaptação das instruções iniciais e dos itens do PTCI envolveu cinco etapas: (1) tradução; (2) retradução; (3) correção e adaptação semântica; (4) validação do conteúdo por profissionais da área (juízes); e (5) teste da versão final, por meio de uma escala verbal-numérica. Como indicadores de desempenho para a compreensão, foram computados os escores de tendência central (média) e dispersão (desvio padrão) para cada item na etapa 5. Definiu-se escore médio ≥ 3 para compreensão satisfatória. RESULTADOS: As 36 questões e as instruções iniciais foram traduzidas e adaptadas para compor a versão brasileira do Posttraumatic Cognitions Inventory . Quarenta e cinco adultos responderam aos itens do Posttraumatic Cognitions Inventory na etapa teste da versão final, mostrando compreensão adequada do instrumento na escala verbal-numérica (M = 4,13; dp = 0,11). CONCLUSÕES: O Posttraumatic Cognitions Inventory é um instrumento de fácil compreensão e semanticamente válido. Estudos posteriores são necessários para a verificação e adequação da avaliação de suas propriedades psicométricas na população brasileira.

Randomized, double-blind trial comparing indinavir alone, zidovudine alone and indinavir plus zidovudine in antiretroviral therapy-naive hiv-infected individuals with CD4 cell counts between 50 and 250/mm3

Treatment with indinavir has been shown to result in marked decreases in viral load and increases in CD4 cell counts in HIV-infected individuals. A randomized double-blind study to evaluate the efficacy of indinavir alone (800 mg q8h), zidovidine alone (200 mg q8h) or the combination was performed to evaluate progression to AIDS. 996 antiretroviral therapy-naive patients with CD4 cell counts of 50-250/mm3 were allocated to treatment. During the trial the protocol was amended to add lamivudine to the zidovudine-containing arms. The primary endpoint was time to development of an AIDS-defining illness or death. The study was terminated after a protocol-defined interim analysis demonstrated highly significant reductions in progression to a clinical event in the indinavir-containing arms, compared to the zidovudine arm (p<0.0001). Over a median follow-up of 52 weeks (up to 99 weeks), percent reductions in hazards for the indinavir plus zidovudine and indinavir groups compared to the zidovudine group were 70% and 61%, respectively. Significant reductions in HIV RNA and increases in CD4 cell counts were also seen in the indinavir-containing groups compared to the zidovudine group. Improvement in both CD4 cell count and HIV RNA were associated with reduced risk of disease progression. All three regimens were generally well tolerated.
