The evolution of international output differences (1960-2000) : from factor to productivity

This article presents a group of exercises of leveI and growth decomposition of output per worker using cross-collntry data from 1960 to :2000. It is shown that at least llntil 197.5 factors of production (capital anel education) ",ere the main source of output dispersion across ecoIlomies and that productivity variance was considerably srnaller than in late years. Qnly after this date the prominence of productivity started to sho\\' up in the data. as the majority of the litcrature has found. The gro\\'th decomposition exercises showecl that t he reversal of relative irnportance of proeluctivity vis-a-\'is factors is explainecl by the very good (bad) performance of procluctivity of fast (slow) growing cconomies. Although growth in the pcriod, on avcragc. is mostly clue to factors accumulation. its variance is explained by productivity.

Estudo de caso: uma reflexão sobre as estruturas internas da Secretaria de Estado de Saúde do Rio de Janeiro para acompanhamento e controle de contratos firmados com a iniciativa privada para gestão de unidades de saúde

Este estudo objetiva comparar as estruturas internas da Secretaria de Estado de Saúde do Rio de Janeiro (SES/RJ) organizadas para a execução do acompanhamento e controle de contratos de gestão firmados com parceiros privados para prestação de serviços de saúde no estado. As modalidades de contratação abordadas foram: “Gestão Compartilhada”, contratação entre a SES/RJ e empresa privada com base na Lei Nº 8.666 de 21 de junho de 1993 e “Gestão por Organização Social de Saúde (OSS)”, contratação entre a SES/RJ e OSS com base na Lei Nº 6.043 de 19 de setembro de 2011. Visando o cumprimento do marco legal no que tange ao controle dos contratos de gestão, a SES/RJ reformulou estruturas internas, instituindo novas instâncias de acompanhamento de contratos. A premência na implantação dos novos mecanismos de gestão assistencial para atendimento às necessidades de saúde da população fluminense prejudicou a avaliação e possível mensuração de custos de transação. Não obstante os contratos de gestão produzam o bem público maior, qual seja a oferta de serviços de saúde de qualidade à população fluminense, há que se considerar que a eficiência é um princípio expresso na Emenda Constitucional nº 19 de 1998 e deve ser perseguida pela Administração Pública. À luz da Teoria de Custos de Transação, a hipótese deste trabalho é que o Poder Público pode incorrer em perdas desconhecidas com a estrutura de governança de contratos com OSS, se custos de transação não forem mensurados. Para avaliar a pertinência da suposição, é proposta comparação com a estrutura de governança de contratos de Gestão Compartilhada.

Occupational ergonomics: Work posture among Brazilian dental students

This study involved observational assessment of work posture in relation to recommended ergonomic posture the requirements necessary for ergonomic posture among students in the final year of a degree program at the School of Dentistry of Araraquara-UNESP/Brazil (n =73) and investigation of the association of work posture with sex, the type of procedure, four-handed dentistry, and the region of the mouth being treated. The work posture of the students during 250 clinical procedures was observed by means of pictures. Each procedure received a posture classification: Adequate, partially adequate, or inadequate. A descriptive statistical analysis was conducted. The prevalence of final posture classification was calculated using 95% confidence intervals and point estimate. Associations of interest were studied using the chi-square test, with a 5% significance level. It was concluded that the prevalence of procedures performed with partially adequate posture was high, and that the final work posture classification was not associated with the variables of interest. © 2013 Taylor & Francis Group.

Aromaterapia e Ansiedade: revisão integrativa da literatura

This study aimed at investigating, in the national and international scientific literature, how aromatherapy is used as a therapeutic tool to reduce anxiety. It is a bibliographic study that adopted integrative literature review as a method. Studies published on databases Scielo, Medline and Cinahl from 2008 to 2012 were selected. A sample of 20 scientific articles was analyzed, and of these, 13 had an experimental and a quasi--experimental design whereas 07 were systematic or integrative reviews. The synthesis of knowledge sho-wed that aromatherapy represents a safe therapeutic practice although it is still underestimated in health care practices. The construction of evidence levels was not possible due to discrepancies in the studied populations, in research designs, the various essential oils used and the different methods for aromatherapy application. The knowledge gaps identified in these studies are related to the need to develop new forms to evaluate the effectiveness of this practice, including the therapist-patient relationship and the different communication forms that are intrinsic to aromatherapy.

Die 18 F-Fluorierung verschiedener Aminosäuren als Tracer für die Tumor-Diagnostik mittels Positronen-Emissions-Tomographie

Die Zielsetzung dieser Arbeit war die Synthese und Markierung, sowie die in vitro- und in vivo-Evaluierung zweier markierter Aminosäure. Es wurden die PET-Tumor-Tracer C1-(2-[18F]Fluoreth- ylamino)-asparagin und S-2-Amino-4-[18F]fluor-butansäure synthetisiert. Die Markierung zum C1-(2-[18F]Fluorethylamino)-asparagin wurde mit 2-[18F]Fluorethylamin als Precursor durchgeführt. Ausgehend von N,N-Dibenzyl-(2-bromethyl)-amin wurde zunächst N,N-Dibenzyl-(2-[18F]fluorethyl)-amin in einer nukleophilen Substiution mit [18F]Fluorid in Acetonitril bei 80 °C mit einer Reaktionsdauer von 5 min dargestellt. Zur Abtrennung überschüssigen [18F]Fluorids wurde das Roh-Produkt auf einer Sep-Pak Plus Kartusche (C18) fixiert und mit Acetonitril eluiert. Die Abspaltung der Benzyl-Schutzgruppen erfolgte durch die Zugabe von Pd/C zu dem eluierten N,N-Dibenzyl-(2-[18F]fluorethyl)-amin und Behandelung der Lösung im leichten Wasserstoffstrom. Im finalen Aufreinigungsschritt wird der Katalysator Pd/C mittels eines Membranfilters abgetrennt. Das 2-[18F]Fluorethylamin wird im Sauren in das Amino-Salz überführt und im Vakuum vom Lösungsmittel befreit. Die Markierung zum C1-(2-[18F]Fluorethylamino)-asparagin wurde in DMF durchgeführt. Die höchsten Ausbeuten werden nach 4 min bei 60 °C erhalten. Die Abspaltung der Schutzgruppe erfolgt durch Trifluoressigsäure bei Raumtemperatur in 8 min. Die Aufreinigung des C1-(2-[18F]Fluorethylamino)-asparagin mittels HPLC und Festphasenextraktion liegt das Produkt in einer isotonischne isotonischen Kochsalzlösung vor. Die in vitro-Versuche wurden mit C1-(2-[18F]Fluorethylamino)-asparagin an 5 verschiedenen Zelllinen durchgeführt, 3 Plattenepitele und 2 Melanome. Hierbei konnte eine erhöhte Akkumulation von C1 -(2-[18F]Fluorethylamino)-asparagin beobachtet werden, die innerhalb von 20 min einen konstanten Wert erreicht. Ein Blockade-Experiment zeigte, dass sich die Aufnahme von C1 -(2-[18F]Fluorethylamino)-asparagin durch gesättinge Asparagin-Lösung bei den Plattenepitelen gar nicht und bei den Melanomen nur leicht vermindern ließ. Da die Aufnahme von C1-(2-[18F]Fluorethylamino)-asparagin in die Zellen höher war als bei FDG bei dem gleichen Versuchsaufbau, wurden in vivo-Versuche angesetzt. Die in vivo-Versuche an Sprague Dawley Ratten mit C1-(2-[18 F]Fluorethylamino)-asparagin zeigten keine messbare Anreicherung von C1-(2-[18F]Fluorethylamino)-asparagin in Tumoren. Fast die komplette Aktivität wurde in der Niere und Blase wiedergefunden. Die Synthese von S-2-Amino-4-[18F]fluor-butansäure wurde über stereodirigierende Auxilliare realisiert. Dazu wurden die geeignetsten Auxillare ausgewählt und auf ihre Eignung verglichen. Der Vergleich der stereodirigierenden Auxilare zeigte, dass das (1R,2R,5R)-2-Hydroxy-2,6,6-trimethyl- bicyclo[3.1.1]hept-3-ylidenamino)-essigsäure tert.-butylester (Laue-Auxillar) am geeignetesten ist. Die 18F-Markierung von S-2-Amino-4-[18F]fluor-butansäure wurde so optimiert, dass eine möglichst hohe stereochemische Reinheit des Produktes erzielt wird. Die optische Reinheit von S-2-Amino-4-[18 F]fluor-butansäure wurde mit > 93 % ee berechnet. Die Synthese des Markierungsvorläufers wurde ausgehend vom Laue-Auxilliar aufgebaut. Als Abgangsgruppe hat sich die Tosylgruppe besonders bewährt. Sie lässt sich unter besonders schonenden Bedingungen in den säurelabilen (1R,2R,5R)-4-Hydroxy-2-(2-hydroxy-2,6,6-trimethyl-bi- cyclo[3.1.1]hept-3-ylidenamino) butansäure tert.-butylester einführen. Bei der 18F-Markierung von S-2-Amino-4-[18F]fluor-butansäure mittels n.c.a. [18F]Fluorid hat sich die Wahl des Basensystems als besonders wichtig erwiesen. Die maximale Ausbeuten von 55% wurde mit Oxalat als Basensystem in Acetonitril bei 80 °C und einer Reaktionszeit von 15 min erzielen. Die Abspaltung der Schutzgruppen und die Abtrennung des Produktes wird in mehreren Schritten durchgeführt einschließlich einer HPLC-Abtrennung. Es wird nach 150 min Synthesedauer das gereinigte S-2-Amino-4-[18F]fluor-butansäure in isotonischer Kochsalzlösung mit einer Ausbeute von > 10 % RCA erhalten. Bei in vivo-Versuchen an Sprague Dawley Ratten reicherte sich der Hauptteil der Aktivität in der Niere an und nur weniger als ein halbes Prozent der applizierten Aktivität fand sich in den Tumoren wieder. Nach 10 min wurde ein maximaler Wert erreicht, der sich bis zum Ende der Messung nicht verändert. Das Verhältnis von Tumoraktivität zu unspezifisch-gebundener Aktivität betrug 2,2. Damit liegt das Verhältnis im Bereich der meisten klinisch eingesetzten PET-Tumor-Tracer wie dem des O-(2-[18F]Fluorethyl)-L-tyrosin mit 1,5.

Petrology and geochemistry of Lipari Island (Aeolian archipelago): constraints on magma genesis and evolution

A full set of geochemical and Sr, Nd and Pb isotope data both on bulk-rock and mineral samples is provided for volcanic rocks representative of the whole stratigraphic succession of Lipari Island in the Aeolian archipelago. These data, together with petrographic observations and melt/fluid inclusion investigations from the literature, give outlines on the petrogenesis and evolution of magmas through the magmatic and eruptive history of Lipari. This is the result of nine successive Eruptive Epochs developing between 271 ka and historical times, as derived from recentmost volcanological and stratigraphic studies, combined with available radiometric ages and correlation of tephra layers and marine terrace deposits. These Eruptive Epochs are characterized by distinctive vents partly overlapping in space and time, mostly under control of the main regional tectonic trends (NNW-SSE, N-S and minor E-W). A large variety of lava flows, scoriaceous deposits, lava domes, coulees and pyroclastics are emplaced, ranging in composition through time from calcalkaline (CA) and high-K (HKCA) basaltic andesites to rhyolites. CA and HKCA basaltic andesitic to dacitic magmas were erupted between 271 and 81 ka (Eruptive Epochs 1-6) from volcanic edifices located along the western coast of the island (and subordinately the eastern Monterosa) and the M.Chirica and M.S.Angelo stratocones. These mafic to intermediate magmas mainly evolved through AFC and RAFC processes, involving fractionation of mafic phases, assimilation of wall rocks and mixing with newly injected mafic magmas. Following a 40 ka-long period of volcanic quiescence, the rhyolitic magmas were lately erupted from eruptive vents located in the southern and north-eastern sectors of Lipari between 40 ka and historical times (Eruptive Epochs 7-9). They are suggested to derive from the previous mafic to intermediate melts through AFC processes. During the early phases of rhyolitic magmatism (Eruptive Epochs 7-8), enclaves-rich rocks and banded pumices, ranging in composition from HKCA dacites to low-SiO2 rhyolites were erupted, representing the products of magma mixing between fresh mafic magmas and the fractionated rhyolitic melts. The interaction of mantle-derived magmas with the crust represents an essential process during the whole magmatic hystory of Lipari, and is responsible for the wide range of observed geochemical and isotopic variations. The crustal contribution was particularly important during the intermediate phases of activity of Lipari when the cordierite-bearing lavas were erupted from the M. S.Angelo volcano (Eruptive Epoch 5, 105 ka). These lavas are interpreted as the result of mixing and subsequent hybridization of mantle-derived magmas, akin to the ones characterizing the older phases of activity of Lipari (Eruptive Epochs 1-4), and crustal anatectic melts derived from dehydration-melting reactions of metapelites in the lower crust. A comparison between the adjacent islands of Lipari and Vulcano outlines that their mafic to intermediate magmas seem to be genetically connected and derive from a similar mantle source affected by different degrees of partial melting (and variable extent of crustal assimilation) producing either the CA magmas of Lipari (higher degrees) or the HKCA to SHO magmas of Vulcano (lower degrees). On a regional scale, the most primitive rocks (SiO2<56%, MgO>3.5%) of Lipari, Vulcano, Salina and Filicudi are suggested to derive from a similar MORB-like source, variably metasomatized by aqueous fluids coming from the slab and subordinately by the additions of sediments.

Inimmaginabile e progetto. Architettura e memoria nei luoghi della Deportazione

La memoria pubblica della Sho'ah è inscritta in una quantità proliferante di immagini e spazi memoriali. Ciò è riscontrabile in modo particolare nei principali "siti dello sterminio" assurti a simbolo nel corso degli anni, mentre molti altri "luoghi di memoria" della Deportazione soffrono di una condizione di intrinseca debolezza. Essa è riconducibile in primo luogo alla fragilità del dato materiale, i cui resti ormai privi di eloquenza risultano difficili da interpretare e conservare, in secondo luogo alla sovrapposizione di memorie concorrenti venutesi a determinare in conseguenza dei riusi successivi a cui queste strutture sono spesso andate soggette dopo la guerra, infine alla difficoltà di rendere espressione compiuta alla tragedia della Deportazione. Il caso del campo di Fossoli è paradigmatico: esso interroga la capacità del progetto di "dare forma" al palinsesto delle memorie, rendendo possibile il riconoscimento ed esplicitando una significazione delle tracce, senza aggiungere ulteriori interpretazioni. Lo spazio e il paesaggio, in quanto linguaggi indentitari, possono offrirsi come strumenti da questo punto di vista. Michel De Certeau vi fa riferimento quando afferma che lo spazio coincide con «l’effetto prodotto dalle operazioni che lo orientano, che lo circostanziano, o temporalizzano e lo fanno funzionare come unità polivalente di programmi conflittuali o di prossimità contrattuali». Lo spazio gioca un ruolo cruciale nel conformare l'esperienza del presente e allo stesso tempo nel rendere visibili le esperienze passate, compresse nella memoria collettiva. Lo scopo di questa ricerca è interrogare le potenzialità spaziali del luogo, considerate sotto il profilo culturale e semantico, come valida alternativa alla forma-monumento nella costruzione di una o più narrazioni pertinenti della memoria.

Isotope ratios of basalts from ODP Leg 115 holes (Table 1)

Strontium, neodymium, and lead isotope ratios are reported for 13 Leg 115 basalts as well as 3 basalts from Texaco drill hole SM-1 on the Mascarene Plateau. The 87Sr/86Sr ratios and eNd range from 0.70330 to 0.70439 and 5.5 to 7.4, respectively, although 87Sr/86Sr ratios higher than 0.70383 are found only in SM-1 basalts. The high 87Sr/86Sr values are thought to reflect seawater Sr in secondary phases, although all samples were strongly leached in HC1 before analysis. 206Pb/204Pb ratios range from 18.53 to 18.80, and sho high 207Pb/204Pb and 208Pb/204Pb ratios relative to 206Pb/204Pb ratios, typical of Indian Ocean mid-ocean ridge (MORB) and oceanic-island basalts (OIB). Isotopic compositions of Leg 115 basalts generally fall between fields for MORB and Reunion Island basalts, consistent with the conclusion drawn from geochronological studies that Deccan flood basalt volcanism, the Chagos-Laccadive Ridge, and the Mascarene Plateau are all products of the Reunion mantle plume. Isotopic compositions of magmas produced by this plume have varied systematically with time in the direction of less "depleted," less MORB-like isotopic signatures. This compositional change has been accompanied by a decrease in eruption rate. We interpret Deccan volcanism as the voluminous beginning of the plume. Reduced entrainment of asthenosphere following melting of the plume head resulted in less MORB-like isotope ratios in magmas and a decrease in eruptive activity with time.
