Controle Gerencial em Empresas Internacionalizadas: Caso Petrobras Uruguay Distribución

Reconhecida como uma das maiores empresas do Brasil, controlada pelo governo, a Petrobras apresenta um processo de internacionalização dividido em duas fases: (i) busca de melhores condições contratuais para o abastecimento do mercado interno e (ii) posicionamento mundial, segurança financeira e internacionalização da marca. Ambas as perspectivas de atuação internacional promoveram o aproveitamento de vantagem competitiva, ainda que sob comportamentos distintos. Diante disso, o objetivo do presente estudo é mensurar o impacto do processo de internacionalização no sistema de controle gerencial da unidade de estudo: Petrobras Uruguay Distribución, subsidiária no segmento de downstream1 e constituída em 2006 por meio de um processo de reorganização societária decorrente da aquisição dos ativos da Shell. Para atender a este propósito, analisam-se as possíveis alterações dos sistemas de controle gerencial e a relação existente, em termos de proximidade e afastamento da literatura presente e o caso estudado. Para tanto, o capítulo de revisão de literatura representa o embasamento teórico responsável pelas abordagens das características dos sistemas de controles, identificação dos contextos influenciadores de seu desenho e destaque para os tipos de internacionalização, nas tangentes comportamentais e motivacionais, além de abordar as teorias de ciclo de vida organizacional. O método aplicado no teste do referencial teórico foi o estudo exploratório com caso único, mediante a aplicação de um questionário padronizado. As variáveis de pesquisa consubstanciaram-se no relacionamento da literatura abordada e as questões de pesquisa e foram classificadas, segundo a natureza, em contingentes e identificadoras. Os resultados obtidos possibilitaram avaliar o nível do impacto do processo de internacionalização e a capacidade de adaptabilidade da organização aos novos contextos, comprovando que o empreendimento de novas estratégias, sejam elas internacionais ou em novos negócios, influencia o desenho do sistema de controle gerencial que refletirá, na proporção do interesse dos gestores, num processo de controle mais adequado à organização.

Regulamentação e criminalização das drogas: a Comissão Nacional de Fiscalização de Entorpecentes e a internalização do proibicionismo no Brasil (1936-1946)

Este trabalho problematiza um tipo específico de racionalidade que emergiu nos fins do século XIX e avançou no século XX, implicando na constituição de uma política mundial destinada à regulamentação de determinadas substâncias psicoativas. Tais práticas foram possíveis em virtude de uma produção discursiva cujos enunciados médico-sanitários reivindicavam a intervenção dos Estados Nacionais em assegurar a saúde coletiva. No caso do uso de psicoativos, tais discursos fizeram emergir uma série de tratados internacionais, leis nacionais, normas e regulações que modificaram o comércio e os hábitos de consumo de tais substâncias, criminalizando qualquer uso que não estivesse de acordo com a legislação vigente. O recorte que esta dissertação procura fazer tem por foco analisar como esse processo se deu no Brasil, mais especificamente a partir da criação da Comissão Nacional de Fiscalização de Entorpecentes CNFE, organização esta de caráter governamental, que após sua criação passou a centralizar as políticas sociais sobre drogas no país. A CNFE foi constituída por meio do Decreto-Lei n 780em 28 de abril de 1936, vinculada ao Ministério das Relações Exteriores em conjunto com o Departamento Nacional de Saúde, através do Serviço de Fiscalização do Exercício Profissional. Neste caso, utilizando a documentação encontrada no Arquivo Histórico do Itamaraty, na Biblioteca de Saúde Pública da Fundação Oswaldo Cruz, Centro de Pesquisa e Documentação da Fundação Getúlio Vargas, dentre outras. Procurei delimitar esta pesquisa nos primeiros dez anos de atuação da Comissão, isto é, entre 1936 e 1946, para tanto, utilizo como instrumento de análise teórico-metodológico duas noções que serviram às reflexões do pensador francês Michel Foucault; biopolítica e governamentalidade. Desta forma, procuro acionar tais noções para localizar as estratégias de poder que culminaram na governamentalização do Estado voltadas para a gestão da vida das populações, tendo como pano de fundo os interditos das políticas sociais sobre drogas.

Karyotypic evolution and phylogenetic relationships in the order Chiroptera as revealed by G-banding comparison and chromosome painting

Bats are a unique but enigmatic group of mammals and have a world-wide distribution. The phylogenetic relationships of extant bats are far from being resolved. Here, we investigated the karyotypic relationships of representative species from four families

Adaptive evolution of MRGX2, a human sensory neuron specific gene involved in nociception

MRGX2, a G-protein-coupled receptor, is specifically expressed in the sensory neurons of the human peripheral nervous system and involved in nociception. Here, we studied DNA polymorphism patterns and evolution of the MRGX2 gene in world-wide human populations and the representative nonhuman primate species. Our results demonstrated that MRGX2 had undergone adaptive changes in the path of human evolution, which were likely caused by Darwinian positive selection. The patterns of DNA sequence polymorphisms in human populations showed an excess of derived substitutions, which against the expectation of neutral evolution, implying that the adaptive evolution of MRGX2 in humans was a relatively recent event. The reconstructed secondary structure of the human MRGX2 revealed that three of the four human-specific amino acid substitutions were located in the extra-cellular domains. Such critical substitutions may alter the interactions between MRGX2 protein and its ligand, thus, potentially led to adaptive changes of the pain-perception-related nervous system during human evolution.

Morphological Adaptations to Drought and Reproductive Strategy of the Moss Syntrichia caninervis in the Gurbantunggut Desert, China

The biological soil crusts (BSCs) in the Gurbantunggut Desert, the largest fixed and semi-fixed desert in China, feature moss-dominated BSCs, which play an indispensable role in sand fixation. Syntrichia caninervis Mitt. (S. caninervis) serves as one of the most common species in BSCs in the desert. In this study we examined the morphological structure of S. caninervis from leafy gametophyte to protonema using light and scanning electron microscopy (SEM). We also examined the relationships between the morphological structure of S. caninervis and environmental factors. We found that: (1) this moss species is commonly tufted on the sand surface, and its leaves are folded upwards and twisted around the stem under dry conditions; (2) the cells on both upper and lower leaf surfaces have C-shaped dark papillae, which may reflect sunlight to reduce the damage from high temperature; (3) the leaf costa is excurrent, forming an awn with forked teeth; and (4) the protonema cells are small and thickset with thick cell walls and the cytoplasm is highly concentrated with a small vacuole. In addition, we also found that the protonema cells always form pouches on the tip of the mother cells during the process of cell polarization. Our results suggest that S. caninervis has, through its life cycle, several morphological and structural characteristics to adapt to dry environmental conditions. These morphological features of S. caninervis may also be found in other deserts in the world due to the world-wide distribution of the species.

Tourism Potential of Agricultural Heritage Systems

Traditional agricultural systems are threatened world-wide mainly due to the introduction of modern agricultural techniques and the emigration of farm labourers from remote rural villages. The objective of the programme 'Globally Important Agricultural Heritage Systems' (GIAHS), initiated by the Food and Agriculture Organization (FAO) of the United Nations in 2002, is dynamic conservation of traditional agricultural systems. This article addresses the definition and content of agricultural heritage systems and discusses conservation options in the light of developing rural tourism. An explorative survey was conducted in Longxian village, situated in Zhejiang Province, southern China, focusing on the tourism potential of a typical Rice-Fish Agricultural System. The identification of heritage resources is a first step in the process of transforming an agricultural landscape into a cultural tourism landscape. However, the future of these landscapes is in the hands of a range of stakeholders and depends on their capacity to manage, in a sustainable way, tourism development strategies alongside conservation policies.

The boundary of palaearctic and oriental realms in western China

In the world-wide zoogeographic division, there has been no consentaneous understanding about the delimitation between palaearctic and oriental realms in western China. In this study, we will discuss the division based on amphibian distribution in Shaanxi, Gansu, Sichuan, Yunnan, and Tibet according to species coefficient similarity between each zoogeographic province. The results show that the northern border lies from Qinling Mountains-Feng Xian (Shaanxi)-Debu (Gansu)-Aba (Sichuan)-Batang-Bomi (Tibet), to Linzhi districts, and the southern border is from Taibai-Feng Xian in Shaanxi-Wen Xian (Gansu)-Songpan-Kangding-Daocheng (Sichuan), to Zhongdian-Gongshan in Yunnan, and westward to Motuo and Bomi district in Tibet.

华北克拉通新生代玄武岩携带的地幔橄榄岩Fe同位素地球化学及含金云母地幔岩岩石学研究

In recent years, thanks to the improvement of analytical methods and the use of MC-ICP-MS, Fe isotope can be measured precisely. Fe isotope shows considerable variation both in biological and inorganic processes (from low T to high T) in nature, Therefore, Fe isotope has become one of the exciting frontier sciences and has favorable prospects of the application to the geosciences and life sciences. Based on a comprehensive review of available references in the related field, this study focuses on the development of techniques for high-precision measurement of iron isotope using MC-ICP-MS, and application of the techniques developed to study the Fe isotopes as well as major and trace element compositions of minerals (Ol, Opx, Cpx and Sp) from spinel peridotitic xenoliths from Cenozoic alkaline basalts to investigate Fe isotopic features of the lithospheric mantle beneath the North China Craton. The minerals from these xenoliths are similar to those off-cratonic peridotites world-wide, but are remarkably different from those on-cratonic peridotites and clinopyroxenes from these spinel lherzolites exhibit two types of chondrite-normalized REE patterns i.e. LREE-depleted and flat or spoon-shaped. It is noted that total abundances of REE in clinopyroxenes from these peridotites show a broad negative correlation with Cr# numbers of Cpx and Sp. The Fe isotope results show that the spinel peridotitic xenoliths have small but distinguishable Fe isotopic variations in minerals (generally Ol < Opx < Cpx) and samples, and the isotopic range in spinel is relatively large. Positive linear relationship with the ε57Fecpx/ε57Feopx ratio close to one unit has been observed between Fe isotopes of coexistent Opx and Cpx, indicating that the Cpx and Opx have generally reached Fe isotopic equilibrium. However, Fe isotopes between the Ol and Sp show apparent disequilibrium. The broadly negative correlation between mineral Fe isotopes and oxygen fugacity (fo2), metasomatic indexes such as spinel Cr#, (La/Yb) N and (La/Sm) N ratios of clinopyroxenes suggest that Fe isotopic variations in different minerals and peridotites were probably produced by melt-peridotite interaction. This study further confirms the previous observation that the lithospheric mantle has distinguishable and heterogeneous Fe isotopic variations at a scale of xenoliths. Mantle metasomatism that induces the interaction of the lithospheric mantle peridotite with metasomatic agent is a most potential mechanism for the Fe isotope fractionation in mantle peridotites. Therefore, Fe isotope could be a new and powerful tool to probe the evolution of the lithospheric mantle. We also report mineral compositions, clinopyroxene trace element concentrations and Sr-Nd isotopes for newly-discovered phlogopite-bearing spinel lherzolite and olivine clinopyroxenite xenoliths from three different localities （Hannuoba, Hebei Province; Jining Sangyitang, Inner Mongolia; Hebi, Henan Province）of the North China Craton. Systematic comparisons with phlogopite-free spinel lherzolite xenolith from the same locality reveals that the phlogopite-bearing peridotitic xenoliths have relatively higher Al2O3, CaO, Na2O, K2O, TiO2 contents and lower MgO contents than those phogopite-free counterparts. The former also has higher LREE concentrations, but relatively less radiogenic Sr-Nd isotopic ratios. This demonstrates that mantle metasomatism can not only enrich the basaltic components and trace element concentrations, but also make a decrease in Mg# of the peridotites and olivines and a relative depletion in Sr-Nd isotopes. 87Rb/86Sr-87Sr/86Sr isochrons of the phlogopite-bearing xenoliths indicate that mantle metasomatism happened in the Mesozoic and/or Cenozoic time. The metasomatic agent was derived from the asthenosphere. The result also manifests that the widespread similarity of the geochemical features such as major and trace elements and isotopic compositions in the Cenozoic lithospheric mantle beneath the North China Craton to those “oceanic” lithospheric mantle could be as a result of the ubiquitous presence of the interaction between the old refractory peridotites and the infiltrated asthenospheric melt, rather than the actually newly-accreted lithospheric mantle.

Can the Continuous Plankton Recorder (CPR) be used to infer sardine diet?

Knowledge on the impact of climate variability in the diet of planktivorous fish is limited by the laborious work involved in stomach content analysis, impractical for large scale studies. Routine measurements of plankton such as the Continuous Plankton Recorder (CPR) survey provide valuable information of the temporal variation of phyto- and zooplankton prey availability for higher trophic levels. Sardines are a world-wide distributed and commercially important planktivorous fish, at the basis of the pelagic marine food web. Being predominantly non-selective filter-feeders, their diets closely correspond to the water plankton species and a significant relationship was recently found between Sardina pilchardus feeding intensity and remotely sensed chlorophyll alpha . Data of sardine stomach prey composition and CPR were obtained during 2003 for the same location off the west coast of Portugal, an area characterised by strong seasonality of plankton abundance and composition, mainly governed by upwelling events. Phyto- and zooplankton prey in sardine stomachs were identified to the lowest possible taxa and their numerical and volumetric abundance was registered, as well as their contribution to the prey carbon content. The seasonal variation of the abundance and composition of sardine diet was then compared to the abundance and composition of the water plankton obtained with the CPR at the same time and for the same area where the fish were collected, in order to evaluate if CPR data can be used to proxy sardine prey availability and diet composition at large temporal scales.

Mining biomedical information from scientific literature

The rapid evolution and proliferation of a world-wide computerized network, the Internet, resulted in an overwhelming and constantly growing amount of publicly available data and information, a fact that was also verified in biomedicine. However, the lack of structure of textual data inhibits its direct processing by computational solutions. Information extraction is the task of text mining that intends to automatically collect information from unstructured text data sources. The goal of the work described in this thesis was to build innovative solutions for biomedical information extraction from scientific literature, through the development of simple software artifacts for developers and biocurators, delivering more accurate, usable and faster results. We started by tackling named entity recognition - a crucial initial task - with the development of Gimli, a machine-learning-based solution that follows an incremental approach to optimize extracted linguistic characteristics for each concept type. Afterwards, Totum was built to harmonize concept names provided by heterogeneous systems, delivering a robust solution with improved performance results. Such approach takes advantage of heterogenous corpora to deliver cross-corpus harmonization that is not constrained to specific characteristics. Since previous solutions do not provide links to knowledge bases, Neji was built to streamline the development of complex and custom solutions for biomedical concept name recognition and normalization. This was achieved through a modular and flexible framework focused on speed and performance, integrating a large amount of processing modules optimized for the biomedical domain. To offer on-demand heterogenous biomedical concept identification, we developed BeCAS, a web application, service and widget. We also tackled relation mining by developing TrigNER, a machine-learning-based solution for biomedical event trigger recognition, which applies an automatic algorithm to obtain the best linguistic features and model parameters for each event type. Finally, in order to assist biocurators, Egas was developed to support rapid, interactive and real-time collaborative curation of biomedical documents, through manual and automatic in-line annotation of concepts and relations. Overall, the research work presented in this thesis contributed to a more accurate update of current biomedical knowledge bases, towards improved hypothesis generation and knowledge discovery.

Commercialization of Biopharmaceuticals

Biotekniikkaa pidetään yhtenä lupaavimmista nykyään tunnetuista teknologioista. Biotekniikan alalta erityisesti uusien lääkeaineiden kehittely on saavuttanut huomiota julkisuudessa. Biotekniikkaa lääkeaineiden kehittämiseen soveltavien yritysten määrä on kasvanut nopeasti viimeisen vuosikymmenen aikana, mutta tämänhetkiset tulokset osoittavat, että yritykset voisivat hyötyä riskien hallintaan ja kaupallistamiseen liittyvien prosessien kehittämisestä. Tutkielma keskittyy biolääkkeiden kaupallistamiseen, erityisesti suomalaisten uusien biolääkeyritysten kannalta. Tutkielma jakaantuu kahteen osaan: ensimmäinen osa tutkii kaupallistamista käsitteenä ja biolääkeliiketoiminnan erityispiirteitä. Toinen osa keskittyy kaupallistamisen empiiriseen tutkimukseen, joka kattaa viisi suomalaista uutta biolääkeyritystä. Empiirisen osan tavoitteena oli tunnistaa ne keinot, jotka auttavat menestyksekkään kaupallistamisprosessin luomisessa tuotekehitysvaiheen läpäisseelle lääkeaineelle. Saavutetut tulokset voidaan tiivistää neljän kriittisen menestystekijän ympärille, jotka ovat 1) tuote, 2) viestintä, 3) uskottavuus ja 4) yhteistyökumppanin valinta. Ensimmäinen menestystekijä on ainutlaatuinen biolääke, joka parantaa kansantaloudellisesti merkittäviä tauteja. Toisen menestystekijän avulla yritys viestittää uudesta ainutlaatuisesta tuotteestaan mahdollisille yhteistyökumppaneilleen. Kolmas menestystekijä kohdistuu yrityksen uskottavuuteen uutena korkean teknologian biolääkeaineiden kehittäjänä. Uskottavuustekijä on erityisen tärkeä suhteiden luomisessa kansainvälisiin lääkeyrityksiin. Neljäs tekijä keskittyy yhteistyökumppanin valintaan, joka alan erityisluonteesta johtuen on tärkeä uudelle biolääkeyritykselle. Viimeiseksi havaittiin, että uusi biolääkeyritys virtuaalisen rakenteensa vuoksi tarvitsee hyvät johdon suhdemarkkinointikyvyt.
