Metodologia adotada pela Secretaria de Estado da Saúde do Estado de São Paulo para avaliação dos hospitais administrados por organizações sociais de saúde na região metropolitana de São Paulo

O tema central deste estudo é descrever e analisar a metodologia de avaliação adotada pela Secretaria de Estado da Saúde de São Paulo para avaliar os hospitais administrados por Organizações Sociais de Saúde (OSS), localizados na região metropolitana de São Paulo. O objetivo é descrever e analisar as dimensões selecionadas pela CGCSS – Coordenadoria de Gestão de Contratos de Serviços de Saúde e identificar os indicadores e as informaçoes geradas pelas OSS e encaminhadas rotineiramente para a CGCSS, além das ações tomadas em relação ao resultado dos indicadores e metas. Trata-se de uma pesquisa qualitativa, exploratória e descritiva, sendo analisados documentos técnicos e realizadas entrevistas semiestruturadas com técnicos da Secretaria de Estado da Saúde de São Paulo e com integrantes da Comissão de Avaliação da Execução dos Contratos de Gestão das Organizações Sociais. Conclui-se que a metodologia de avaliação de desempenho da OSS atende ao disposto na legislação estadual constante na lei nº 846/98, por meio do controle dos indicadores acordados previamente. Porém, a metodologia carece de indicadores capazes de avaliar a qualidade do serviço e o uso dos recursos financeiros. Um dos fatores relevantes em relação à pesquisa foi a falta de acesso aos dados, o que constitui a falta de publicização dos dados, por parte da SES/SP. Porém com a ajuda de alguns membros da comissão foi possível o acesso tardio, por entenderem ser informações públicas.

The effect of skin examination surveys on the incidence of basal cell carcinoma in a Queensland community sample: A 10-year longitudinal study

Skin cancers pose a significant public health problem in high-risk populations. We have prospectively monitored basal cell carcinoma (BCC) and squamous cell carcinoma (SCC) incidence in a Queensland community over a 10-y period by recording newly treated lesions, supplemented by skin examination surveys. Age-standardized incidence rates of people with new histologically confirmed BCC were 2787 per 100,000 person-years at risk (pyar) among men and 1567 per 100,000 pyar among women, and corresponding tumor rates were 5821 per 100,000 pyar and 2733 per 100,000 pyar, respectively. Incidence rates for men with new SCC were 944 per 100,000 pyar and for women 675 per 100,000 pyar; tumor rates were 1754 per 100,000 pyar and 846 per 100,000 pyar, respectively. Incidence rates of BCC tumors but not SCC tumors varied noticeably according to method of surveillance, with BCC incidence rates based on skin examination surveys around three times higher than background treatment rates. This was mostly due to an increase in diagnosis of new BCC on sites other than the head and neck, arms, and hands associated with skin examination surveys and little to do with advancing the time of diagnosis of BCC on these sites as seen by a return to background rates following the examination surveys. We conclude that BCC that might otherwise go unreported are detected during skin examination surveys and thus that such skin cancer screening can influence the apparent burden of skin cancer.

Revista cult: canal de expressão pública da produção intelectual

O objetivo deste estudo é analisar, uma perspectiva histórico-sociológica, o papel desempenhado pela imprensa especializada, no caso pela revista cult, na promoção e divulgação de conteúdos relacionados à cultura com o intuito de investigar se a mesma pode ser entendida como canal de expressão pública da produção intelectual. A intenção é contribuir com as discussões em torno do jornalismo cultural, entendendo-o como uma das variáveis do trabalho jornalístico com especificidades que lhe são determinantes. Ainda hoje essa especialidade tem sofrido generalizações como se uma única característica servisse de base para o que representa. Entretanto, a partir da revisão bibliográfica sobre o tema e de uma análise qualitativa do conteúdo da revista, confirmou-se a hipótese inicial de que o universo denominado "jornalismo cultural" corresponde a uma dinãmica mais ampla e complexa da que lhe é atualmente conferida. Rompeu-se, dessa forma, com a visão simplificadora da cobertura da área, comprovando a existência de uma mídia que atua como espaço de reflexão, sendo responsável pela difusão e propagação de bens simbólico-culturais.(AU)

Heterodimers and family-B GPCRs:RAMPs, CGRP and adrenomedullin

RAMPs (receptor activity-modifying proteins) are single-pass transmembrane proteins that associate with certain family-B GPCRs (G-protein-coupled receptors). Specifically for the CT (calcitonin) receptor-like receptor and the CT receptor, this results in profound changes in ligand binding and receptor pharmacology, allowing the generation of six distinct receptors with preferences for CGRP (CT gene-related peptide) adrenomedullin, amylin and CT. There are three RAMPs: RAMP1-RAMP3. The N-terminus appears to be the main determinant of receptor pharmacology whereas the transmembrane domain contributes to association of the RAMP with the GPCR. The N-terminus of all members of the RAMP family probably contains two disulphide bonds; a potential third disulphide is found in RAMP1 and RAMP3. The N-terminus appears to be in close proximity to the ligand and plays a key role in its binding, either directly or indirectly. BIBN4096BS, a CGRP antagonist, targets RAMP1 and this gives the compound very high selectivity for the human CGRP(1) receptor.

Accounting students' perceptions of a Learning Management System:an international comparison

Purpose - The purpose of this study is to investigate student perceptions of the design features included in an off the shelf Learning Management System (LMS) in teaching undergraduate accounting students. Design/methodology/approach - Questionnaire responses from 846 accounting students studying in the UK, Australia and New Zealand provide international data to develop a model to explain student perception of the LMS. Findings - The final model shows student satisfaction with the use of a LMS is positively associated with three variables: usefulness of lecture notes, bulletin boards and discussion forums, and other LMS tools. Further, the comparison of cultural differences of the three countries shows all students treat the provision of notes as a desirable attribute on a LMS. Findings also suggest that although students find the provision of materials over the LMS does not enhance student engagement in class, overall a comparison of the three countries shows all students treat the provision of notes as a desirable attribute of a LMS. Research limitations/implications - Future research should collect ethnicity data to enable an analysis of cultural influence on student perceptions of the LMS. Practical implications - As increased motivation to learn is found to contribute to improved achievement of learning outcomes, the study's findings have implications for faculty contemplating the adoption of a LMS in their courses. The findings specifically confirm that usefulness of lecture notes, use of bulletin/discussion boards, and other LMS tools are positively endorsed by students and hence increase their motivation to learn. Originality/value - The current paper adds to the literature as the motivation to use and engage with LMSs by accounting students is not well understood. © Emerald Group Publishing Limited.

Relationships between sensory sensitivity, anxiety and selective eating in children

The present study examines whether parental reports of child selective eating are associated with child anxiety and sensitivity to sensory stimuli in their environment. Parents of 95 children aged 5-10 completed questionnaires about child eating behavior, child anxiety and sensory sensitivity. Results indicated that both anxiety and sensory sensitivity were associated with selective eating. In addition, child sensory sensitivity fully mediated the relationship between anxiety and selective eating in children suggesting that it is greater sensitivity to sensory information which explains why more anxious children are more likely to be selective eaters. Further research is necessary to better understand these relationships and indicate whether gradual exposure interventions with children who are sensory sensitive may help to prevent or reduce selective eating. © 2012 Elsevier Ltd.

The formation of phosphatidylcholine oxidation products by stimulated phagocytes

Phagocytic cells produce a variety of oxidants as part of the immune defence, which react readily both with proteins and lipids, and could contribute to the oxidation of low density lipoprotein in atherosclerosis. We have investigated the oxidation of phospholipid vesicles by neutrophils and mononuclear cells, to provide a model of lipid oxidation in the absence of competing protein. Phorbol 12-myristate 13-acetate-stimulated neutrophils were incubated with phospholipid vesicles containing dipalmitoyl phosphatidylcholine, palmitoyl-arachidonoyl phosphatidylcholine (PAPC) and stearoyl-oleoyl phosphatidylcholine, before extraction of the lipids for analysis by HPLC coupled to electrospray mass spectrometry. The formation of monohydroperoxides (814 m/z) and bis-hydroperoxides (846 m/z) of PAPC was observed. However, the major oxidized product occurred at 828 m/z, and was identified as 1-palmitoyl-2-(5,6-epoxyisoprostane E-2)-sn-glycero-3-phosphocholine. These products were also formed in incubations where the neutrophils were replaced by mononuclear cells, and the amounts produced per million cells were similar. These results show that following oxidative attack by phagocytes stimulated by PMA, intact phospholipid oxidation products can be detected. The identification of an epoxyisoprostane phospholipid as the major product of phagocyte-induced phospholipid oxidation is novel, and in view of its inflammatory properties has implications for phagocyte involvement in atherogenesis.

Practical, Computation Efficient High-Order Neural Network for Rotation and Shift Invariant Pattern Recognition

In this paper, a modification for the high-order neural network (HONN) is presented. Third order networks are considered for achieving translation, rotation and scale invariant pattern recognition. They require however much storage and computation power for the task. The proposed modified HONN takes into account a priori knowledge of the binary patterns that have to be learned, achieving significant gain in computation time and memory requirements. This modification enables the efficient computation of HONNs for image fields of greater that 100 × 100 pixels without any loss of pattern information.

Marketing és vállalatközi kapcsolatok - Kutatócsoport zárótanulmány

Tanulmányunkban a Marketing és Vállalatközi kapcsolatok kutatócsoport 2011-ben készült műhelytanulmányainak legfontosabb eredményeit mutatjuk be. Kutatásaink központi témája a vállalati versenyképesség, illetve annak vizsgálata, hogy a vállalatok tevékenységének egyes területei hogyan járulnak hozzá a vállalatok versenyképességének növeléséhez. Elemzéseink a Budapesti Corvinus Egyetem Vállalatgazdaságtan Intézete Versenyképesség Kutató Központja által vezetett „Versenyben a világgal” kutatási program nagyszabású kérdőíves felmérésén alapulnak, amely során 300 vállalat vezetőit kérdeztek meg 2009-ben. Eredményeink közül kiemeljük, hogy a piacorientáció szintje a vizsgált vállalati körben az átlagosnál valamivel jobb, azonban a marketingkoncepció jobb megvalósítása érdekében a vállalatoknak a versenytárs-orientációjukat kellene elsősorban erősíteniük. Fontos következtetése a kutatásnak a vezető vállalatok gyakorlatának feltérképezése, e kategóriát egy összetett teljesítménymutató alapján alakítottunk ki. Eredményeink szerint a vezető vállalatok a piacorientáció mértékében, a márkázásban, a disztribúció kiterjedtségében, valamint változatosságában, a marketing erőforrásokban és képességekben és a vállalati hálózatban betöltött pozíció terén erősebbek az átlagosan teljesítőktől és/vagy a lemaradóktól. ----- Abstract: In this research paper we present the most important results of the research papers prepared by the research group „Marketing and Interfirm Relationship” in 2011. The central theme of our research papers is corporate competitiveness. We investigate the ways the different activities of firms contribute to the increase of their competiveness. Our analyses are based on a large scale survey carried out by the Competitiveness Research Center of Corvinus University Of Budapest, in which 300 company executives were surveyed in 2009. Among our results we highlight that market orientation of Hungarian firms is little above the average in our sample, however a better implementation of the marketing concept would require a stronger emphasis on competitor orientation. An important conclusion of our research is the description of the practice of leading companies, a category created in terms of a complex performance measurement. Our results suggest that leading companies show a higher level of market orientation, a more sophisticated branding practice, a more extended distribution system with a higher degree of variablity, stronger marketing resources and capabilities and a stronger position in the firm’s network than companies with average performance and/or laggards.

Sedimentation rates and geochemical analysis of surface sediments from the South Atlantic

Extensive investigations of sedimentary barium were performed in the southern South Atlantic in order to assess the reliability of the barium signal in Antarctic sediments as a proxy for paleoproductivity. Maximum accumulation rates of excess barium were calculated for the Antarctic zone south of the polar front where silica accumulates at high rates. The correspondence between barium and opal supports the applicability of barium as a proxy for productivity. Within the Antarctic zone north of today's average sea ice maximum, interglacial vertical rain rates of excess barium are high, with a maximum occurring during the last deglaciation and early Holocene and during oxygen isotope chronozone 5.5. During these periods, the maximum silica accumulation was supposedly located south of the polar front. Glacial paleoproductivity, instead, was low within the Antarctic zone. North of the polar front, significantly higher barium accumulation occurs during glacial times. The vertical rain rates, however, are as high as in the glacial Antarctic zone. Therefore there was no evidence for an increased productivity in the glacial Southern Ocean.

Expanded GHOST database

In this study we review a global set of alkenone- and foraminiferal Mg/Ca-derived sea surface temperatures (SST) records from the Holocene and compare them with a suite of published Eemian SST records based on the same approach. For the Holocene, the alkenone SST records belong to the actualized GHOST database (Kim, J.-H., Schneider R.R., 2004). The actualized GHOST database not only confirms the SST changes previously described but also documents the Holocene temperature evolution in new oceanic regions such as the Northwestern Atlantic, the eastern equatorial Pacific, and the Southern Ocean. A comparison of Holocene SST records stemming from the two commonly applied paleothermometry methods reveals contrasting - sometimes divergent - SST evolution, particularly at low latitudes where SST records are abundant enough to infer systematic discrepancies at a regional scale. Opposite SST trends at particular locations could be explained by out-of-phase trends in seasonal insolation during the Holocene. This hypothesis assumes that a strong contrast in the ecological responses of coccolithophores and planktonic foraminifera to winter and summer oceanographic conditions is the ultimate reason for seasonal differences in the origin of the temperature signal provided by these organisms. As a simple test for this hypothesis, Eemian SST records are considered because the Holocene and Eemian time periods experienced comparable changes in orbital configurations, but had a higher magnitude in insolation variance during the Eemian. For several regions, SST changes during both interglacials were of a similar sign, but with higher magnitudes during the Eemian as compared to the Holocene. This observation suggests that the ecological mechanism shaping SST trends during the Holocene was comparable during the penultimate interglacial period. Although this "ecology hypothesis" fails to explain all of the available results, we argue that any other mechanism would fail to satisfactorily explain the observed SST discrepancies among proxies.

Age of bottom sediments from the South Atlantic Rise as indicated by 14C data for stations of R/V Professor Shtokman

Sedimentation of pelagic biogenic coccolithic-foraminiferal sediments predominates in the section of the South Atlantic ridge between 20° and 30°S. Sedimentation rate and thickness of Late Quaternary sediments differ in the rift valley, the crestal section of the ridge, its flanks and transform faults. Holocene and layers representing the most recent and pen¬ultimate continental glaciations and the last interglacial are distinguishable in the late Quaternary profile. During their development, changes in the mean annual sea surface temperature in the tropical zone of the South Atlantic were minimal, i.e. 1-2°C.
