Acquisition and Loss of the Public Law Status of Entrepreneur – Interpretation Problems of Public Commercial Law in Poland
Authors: Etel Maciej
Published: August 2013

The obligation of the legalization of entrepreneurial activity from Article 14 of The Act of July 2, 2004 on the freedom of entrepreneurial activity caused deliberations regarding constitutive or declarative character of the legalization entry and as a result, created a problem with indication of the moment when the public law status of an entrepreneur is acquired (or respectively - lost). The answer to the question whether Central Register and Information of Entrepreneurial Activity or the register of entrepreneurs of the National Court Register have also the creation function incites many controversies and is subject to discussions, in the process of which two main standpoints were formed. It is also important to note that the resolution of the discussed issue not only holds scientific value, but above all, it has significant importance in practice. Therefore, it is necessary and even essential. Furthermore, it is typical for this issue that concerns related thereto and arguments raised during the discussion have their basis in the legislation in force and in fact, encapsulate the favoured path of its interpretation.
Study Regarding the Effectiveness of Manual Lymphatic Drainage in the Case of Patients with Breast Cancer that Present Lymphedema
Authors: Mioc Alexandru , Pantea Corina
Published: August 2013

Lymphedema is defined as a persistent increase of tissue volume caused by the blocked or absent lymphatic drainage. The purpose of this study is to analyse the effectiveness of lymphatic drainage in the treatment of lymphedema after a mastectomy, with the aim of reducing the volume of the lymphedema and improving overall symptomatology, as well as providing information regarding the impact of this treatment on quality-of-life and the physical limitations of these patients. With these objectives in mind, a series of articles evaluating the effectiveness of manual lymphatic drainage in the case of patients with breast cancer and lymphedema have been studied. The parameters under observation were: duration of lymphedema reduction and improved symptomatology (pain, a feeling of swelling of the upper limb, functional limitation, and patient dissatisfaction towards their body image). Following this analysis, one can conclude that the association of manual lymphatic drainage to physical exercise and physiotherapy has produced changes in the volume of the limb affected by the lymphedema; however, its isolated use has not resulted in significant changes
A Statistical and Technical-Tactical Study of the Dribbles Conducted by Three Midfielders in Three 1st League matches, in the 2011-2012 Competitive Year
Authors: Brîndescu Sorin
Published: August 2013

Technical preparation implies training increasingly skilled players, with an ever-improving capacity of performing, in order to succeed and cope with the demands of contemporary football. In order to achieve this objective, a continuous increase of quality and efficiency when selecting the players is needed; furthermore, the optimization of the process of preparation and discovery of the most efficient methods in the training process are also necessities to be dealt with. By observing the various technical executions made by the players on the football field, one can obtain practical demonstrations and optimal solutions of how to improve the technical-tactical way of playing of the entire team and can foreground the problematic areas and the less skilled executions of each player and of the entire team
Recovery and Rehabilitation in Football

Published: August 2013

The main purpose of game analysis is to provide the coach with information about the team or the individual performances. This way, the coach as well as the players, noticing the former performances, obtain detailed information about the aspects of the game that could be improved. Nine games have been analysed, on three different age groups (under 12, under 14, under 15). Three games of each age group have been analysed. The specific instructions given to the goalkeepers about the team’s tactic or the weather conditions are not available in this study. For the analysis of every game, a specific system of manual notes has been developed. Concisely, the short throws, like passes and throws (under the arm, as well as over the arm) are more successful than the long throws, in the matter of keeping possession as well as producing passes. Accordingly, the short throws that lead to longer successions of passes, tend to lead to improvements in the players’ technical abilities. Although, the implications for coaches have been underlined as follows, they have to be aware of the specific value of this type of throws and encourage their use when it is required.
Diversity and Community Structure of Oribatid Mites (Acari, Oribatei) at Memorial Complexes of a Megapolis
Authors: Kolodochka L. A. , Shevchenko O. S.
Published: August 2013

In different types of substrate (soil, litter, lichens and mosses) collected at three memorial complexes (cemeteries) of Kyiv (Ukraine), 70 species from 57 genera, 34 families of oribatid mites were found. A few eurytopic species capable of tolerance to different types of pollution make up an essential part in each species complex. The species diversity and complexity of oribatid community structure at researched areas increased with distance from the city center. There was no direct relation between the degree of dominance of most common species and the cemetery’s relative remoteness from the center of the city.

Rain-Call Dialects of the Chaffinch, Fringilla coelebs (Fringillidae), in Ukraine
Authors: Tsvelykh A. N. , Yablonovska-Grishchenko E. D.
Published: August 2013

Four types of Chaffinch rain-calls were found in Ukraine: “rülsch” - a trill signal widely spread in Europe; “hui” - a whistle signal that occurs in North-Western and Central Europe; “Crimean” whistle signal known only from Crimean peninsula and “Caucasian” signal occurring in Caucasus, Asia Minor and Balkans. Sonograms of rendition versions are given for all of the call types. Distribution of dialects of Chaffinch rain-calls in Ukraine was examined. “Rülsch”- dialect occurs at most of the plane Ukraine and Carpathians. Owing to colonizing artificial afforestations in steppe zone this dialect population’s range expanded southward to the coast of the Black and Azov seas. “Hui”-dialect is spread in the Lower Danube region. At the North-Eastern Danube delta Chaffinch’s with “hui”- and “rülsch”- rain-calls are found together and a bird was found that uttered both signals alternately but hybrid signals were not registered. It may attest to recent invasion by “rülsch”- population of Chaffinch’s there. “Crimean” dialect is distributed in mountainous Crimea and in most of the Crimean steppe zone. “Caucasian” rain-call renditions are registered in cases of individual vagrant birds in eastern Crimea and Lower Danube region

Les dispositifs d'alerte dans les entreprises : whistleblowing vs. droit d'alerte
Authors: Boyer Tristan
Published: August 2013

Le rôle croissant des règles de corporate governance et de la responsabilité sociale des entreprises dans les grandes entreprises a conduit à la généralisation de dispositifs d’alerte éthique ou professionnelle selon le modèle du whistleblowing défini par la loi Sarbanes-Oxley. Mesurant et analysant les difficultés et limites de l’importation d’un concept de common law dans un contexte légal continental, cet article propose de dépasser les limites de ces systèmes à travers l’analyse des dispositifs de droit d’alerte qui existent en droit français et dont le potentiel en matière d’efficacité et de légitimité collective paraît plus développé.
Introduction : les équivoques du rire
Authors: Morin Olivier
Published: August 2013

Ce numéro de Terrain envisage l’expression du rire dans toute la variété de ses dimensions – cognitive, sociale, politique. Cette introduction tente de mettre en lumière un aspect du rire (et de ce qui le provoque) qui semble apparaître sous chacun de ces angles : l’ambiguïté. Les théories à l’heure actuelle les plus abouties du mécanisme cognitif du rire (qui reprennent un modèle philosophique bien plus ancien) en font une réaction sophistiquée à la résolution d’une ambiguïté. D’un coup, une stimulation incongrue, qui offrait plusieurs interprétations possibles, n’en admet plus qu’une. L’usage social du rire, tel que l’explore l’anthropologie, montre cependant que le rire ne se limite pas à cette seule fonction (signaler une ambiguïté résolue). Il permet au contraire de mettre en valeur, et parfois de créer, des situations équivoques et des intentions incertaines. Dans la sphère politique, cette ambivalence constitutive du comique en fait un outil particulièrement difficile à prendre en main, aussi bien pour le pouvoir politique que pour ceux qui le contestent. Une anthropologie politique du rire (qui s’esquisse dans plusieurs contributions à ce numéro) est en mesure de montrer que la subversion comique ne se restreint pas aux sociétés dominées par des États ; même dans ces dernières, elle est loin de ne servir que les adversaires des hiérarchies en place.
Rire en situation de violence
Authors: Moussaoui Abderrahmane
Published: August 2013

Rire dans les moments les plus graves peut être le signe manifeste du mépris ou de l’indifférence à l’égard d’une situation. Il peut signifier également une tentative de juguler ses probables débordements dont on craint les effets dévastateurs. De telles raisons peuvent suffire, en temps de paix, à justifier la présence ou le surgissement du rire dans ces moments de fatalité ou d’impuissance. En ces circonstances, le rire est sérieusement ritualisé et son espace-temps rigoureusement défini, de manière à garantir aux membres du groupe ébranlé un bénéfice ardemment espéré. Le rire paraît toutefois plus surprenant quand, avec insolence et désinvolture, de manière quasi impromptue, il vient s’introduire au cœur du tragique dans les moments extrêmes de folie humaine. En revenant sur la décennie de violence meurtrière qu’a vécue l’Algérie dans les années 1990, je tenterai de faire ressortir quelques-uns des différents sens que peut prendre le rire en situation de violence.
Modernité, corps et transformation de soi
Authors: Besnier Niko
Published: August 2013

Aux îles Tonga, la fin des années 2000 fut marquée par une véritable explosion des salons de coiffure dans la petite capitale, Nuku’alofa. Ce phénomène reflète de nouvelles manières de concevoir le corps, par lesquelles les Tongiennes cherchent à se distancier de la vie traditionnelle sans néanmoins s’en affranchir. Les hommes transgenres, appartenant à une catégorie marginalisée quoique importante, jouent un rôle pivot dans ces transformations corporelles grâce au sens esthétique et au sens de la propreté qu’on leur attribue. Ce cas ethnographique permet de proposer une approche de la modernité telle qu’elle opère et se manifeste via les transformations du corps, et d’observer le rôle potentiellement important qu’y jouent les membres de catégories sociales marginalisées.
Tapasin Facilitation of Natural HLA-A and -B Allomorphs Is Strongly Influenced by Peptide Length, Depends on Stability, and Separates Closely Related Allomorphs

Published: August 2013

Despite an abundance of peptides inside a cell, only a small fraction is ultimately presented by HLA-I on the cell surface. The presented peptides have HLA-I allomorph-specific motifs and are restricted in length. So far, detailed length studies have been limited to few allomorphs. Peptide–HLA-I (pHLA-I) complexes of different allomorphs are qualitatively and quantitatively influenced by tapasin to different degrees, but again, its effect has only been investigated for a small number of HLA-I allomorphs. Although both peptide length and tapasin dependence are known to be important for HLA-I peptide presentation, the relationship between them has never been studied. In this study, we used random peptide libraries from 7- to 13-mers and studied binding in the presence and absence of a recombinant truncated form of tapasin. The data show that HLA-I allomorphs are differentially affected by tapasin, different lengths of peptides generated different amounts of pHLA-I complexes, and HLA-A allomorphs are generally less restricted than HLA-B allomorphs to peptides of the classical length of 8–10 aa. We also demonstrate that tapasin facilitation varies for different peptide lengths, and that the correlation between high degree of tapasin facilitation and low stability is valid for different random peptide mixes of specific lengths. In conclusion, these data show that tapasin has specificity for the combination of peptide length and HLA-I allomorph, and suggest that tapasin promotes formation of pHLA-I complexes with high on and off rates, an important intermediary step in the HLA-I maturation process.
Retinoid X Receptor Agonists Modulate Foxp3+ Regulatory T Cell and Th17 Cell Differentiation with Differential Dependence on Retinoic Acid Receptor Activation
Authors: Takeuchi Hajime , Yokota-Nakatsuma Aya , Ohoka Yoshiharu , Kagechika Hiroyuki , Kato Chieko , Song Si-Young , Iwata Makoto
Published: August 2013

Retinoic acid (RA) enhances TGF-β–dependent differentiation of Foxp3+ inducible regulatory T cells (iTregs) and inhibits Th17 differentiation by binding to the RA receptor (RAR)/retinoid X receptor (RXR) heterodimer. The major physiologic RA, all-trans-RA, binds to RAR but not to RXR at physiological concentrations. It remained unclear whether RXR-mediated stimulation affected the iTregs and Th17 differentiation. We found in this study that the RXR agonists, PA024 and tributyltin, augmented the ability of all-trans-RA or the RAR agonist Am80 to enhance CD4+CD25− T cells to acquire Foxp3 expression and suppressive function. However, they failed to enhance Foxp3 expression in the presence of the RAR antagonist LE540, suggesting that the effect depends on RAR-mediated signals. They exerted the effect largely by augmenting the ability of all-trans-RA to suppress the production of IL-4, IL-21, and IFN-γ that inhibited Foxp3 expression. Agonists of peroxisome proliferator-activated receptors and liver X receptors (LXRs), permissive partners of RXR, failed to enhance Foxp3 expression. In contrast, RXR agonists and LXR agonists suppressed IL-17 expression. The RXR-mediated suppression was not canceled by blocking RAR stimulation but was likely to involve permissive activation of LXRs. All-trans-RA and an agonist of RXR or LXR additively suppressed IL-17 expression when the all-trans-RA concentration was low. RXR agonists also suppressed Ccr6 expression that is essential for Th17 cells to enter the CNS. Accordingly, tributyltin treatment of mice ameliorated experimental autoimmune encephalomyelitis through regulating Th17 cell activities. These results suggest that RXR stimulation modulates Foxp3+ iTreg and Th17 differentiation with differential dependence on RAR-mediated stimulation.
Insights into the Role of Bcl6 in Follicular Th Cells Using a New Conditional Mutant Mouse Model

Published: August 2013

The transcriptional repressor Bcl6 controls development of the follicular Th cell (TFH) lineage, but the precise mechanisms by which Bcl6 regulates this process are unclear. A model has been proposed whereby Bcl6 represses the differentiation of T cells into alternative effector lineages, thus favoring TFH cell differentiation. Analysis of T cell differentiation using Bcl6-deficient mice has been complicated by the strong proinflammatory phenotype of Bcl6-deficient myeloid cells. In this study, we report data from a novel mouse model where Bcl6 is conditionally deleted in T cells (Bcl6fl/flCreCD4 mice). After immunization, programmed death -1 (PD-1)high TFH cells in Bcl6fl/flCreCD4 mice are decreased >90% compared with control mice, and Ag-specific IgG is sharply reduced. Residual PD-1highCXCR5+ TFH cells in Bcl6fl/flCreCD4 mice show a significantly higher rate of apoptosis than do PD-1highCXCR5+ TFH cells in control mice. Immunization of Bcl6fl/flCreCD4 mice did not reveal enhanced differentiation into Th1, Th2, or Th17 lineages, although IL-10 expression by CD4 T cells was markedly elevated. Thus, T cell–extrinsic factors appear to promote the increased Th1, Th2, and Th17 responses in germline Bcl6-deficient mice. Furthermore, IL-10 may be a key target gene for Bcl6 in CD4 T cells, which enables Bcl6 to promote the TFH cell phenotype. Finally, our data reveal a novel mechanism for the role of Bcl6 in promoting TFH cell survival.
T Cell CD3ζ Deficiency Enables Multiorgan Tissue Inflammation

Published: August 2013

Although a population of T cells with CD3ζ chain deficiency has been found in patients with systemic lupus erythematosus, rheumatoid arthritis, cancer, and infectious disease, the role of CD3ζ chain in the disease pathogenesis remains unknown. To understand the contribution of CD3ζ deficiency to the expression of organ injury, we have performed the following studies. We used CD3ζ-deficient mice to investigate the role of CD3ζ in the pathogenesis of organ tissue inflammation. We found that the CD3ζ−/− mice can spontaneously develop significant organ inflammation that can be accelerated following the administration of polyinosinic:polycytidylic acid or allogeneic cells (graft versus host). T cells from CD3ζ−/− mice display increased expression of the adhesion molecules CD44 and CCR2 and produce increased amounts of IFN-γ blockade, which mitigates tissue inflammation. Our results demonstrate that CD3ζ deficiency bestows T cells with the ability to infiltrate various tissues and instigate inflammation. Decreased CD3ζ expression noted in T cells from various diseases contributes independently to tissue inflammation and organ damage. Approaches to restore CD3ζ expression of the surface of T cells should be expected to mitigate tissue inflammation.
The CD226/CD155 Interaction Regulates the Proinflammatory (Th1/Th17)/Anti-Inflammatory (Th2) Balance in Humans

Published: August 2013

CD226 costimulatory signals strongly promote Th1 differentiation, enhancing IFN-γ production by naive T cells. We recently reported that knockdown of CD226 on human T cells resulted in a decrease in T-bet and IFN-γ expression. However, the role of CD226 on Th2 and Th17 cells remains unknown. In this study, we found that CD226 and its ligand CD155 were decreased on Th2-polarized naive T cells, whereas both were highly expressed under Th17 conditions. Most IFN-γ– and IL-17–producing cells expressed high levels of CD226, but production of IL-13 did not correlate with CD226 expression. CD226 knockdown by lentiviral transduction resulted in increased STAT-6 phosphorylation, enhanced GATA3 expression, and consequently higher production of IL-4 and IL-13. Under Th17 conditions, CD226-depleted cells showed slightly impaired IL-17 secretion, suggesting that CD226 contributes, in part, to IL-17 production but is dispensable for Th17 cell generation. In line with these results, CD226 blockade with neutralizing Abs efficiently inhibited T cell activation and proliferation and production of IFN-γ and IL-17, whereas IL-13 secretion remained functional. Taken together, our results establish an important role for CD226 in differentially regulating the proinflammatory (Th1/Th17)/anti-inflammatory (Th2) balance, suggesting that the CD226/CD155 interaction could potentially be targeted in therapeutic approaches to human autoimmune diseases.
Till geochemical signatures of volcanogenic massive sulphide deposits in glaciated terrain: a summary of Canadian examples
Authors: McClenaghan M B , Peter J M
Published: August 2013

Volcanogenic massive sulphide deposits are a significant source of Cu, Pb, Zn, and Ag in Canada. In the glaciated landscape of Canada, till geochemistry is an important exploration method for VMS deposits. This open file report provides an overview of the
>50 year history of the application of till geochemical methods to VMS exploration in Canada, and also summarizes appropriate size fractions of till to analyze, analytical techniques, and pathfinder elements. Geochemical methods are now well developed and widely used, most commonly
employing the <0.063 mm till fraction and an extensive suite of VMS pathfinder elements, including Cu, Pb and Zn, Ag, Au, Tl, Sn, Se, Hg, In, Cd, Bi, As, Sb, and Ge. In order to detect the clastic glacial dispersal signal down-ice of a VMS deposit, collection and analysis of unoxidized to
weakly oxidized till is optimal, whereas B-horizon soil is not. Case studies and examples of glacial dispersal patterns associated with VMS deposits from major mining camps and deposits across Canada are highlighted, including Buchans, Bathurst, Timmins, Noranda, Manitouwadge, Flin Flon, Finlayson
Lake, Hackett River, and Izok Lake.

The Poisson boundary of CAT(0) cube complex groups

Published: August 2013

We consider a finite dimensional, locally finite CAT(0) cube complex

X

admitting a co-compact properly discontinuous countable group of automorphisms

G

. We construct a natural compact metric space

B(X)

on which

G

acts by homeomorphisms, the action being minimal and strongly proximal. Furthermore, for any generating probability measure on

G

,

B(X)

admits a unique stationary measure, and when the measure has finite logarithmic moment, it constitutes a compact metric mean-proximal model of the Poisson boundary. We identify a dense invariant

G_\delta

subset

\mathcal{U}_{\,\rm NT}(X)

of

B(X)

which supports every stationary measure, and on which the action of

G

is Borel-amenable. We describe the relation of

\mathcal{U}_{\,\rm NT}(X)

and

B(X)

to the Roller boundary. Our construction can be used to give a simple geometric proof of property A for the complex. Our methods are based on direct geometric arguments regarding the asymptotic behavior of halfspaces and their limiting ultrafilters, which are of considerable independent interest. In particular we analyze the notions of median and interval in the complex, and use the latter in the proof that

B(X)

is the Poisson boundary via the strip criterion developed by V. Kaimanovich.

Published: August 2013

Promastigote miltefosine (MIL) susceptibility was performed on Leishmania donovani isolates from Indian patients with visceral leishmaniasis treated with MIL. Isolates that were obtained before the onset of MIL treatment, after completion of treatment (29th day), or at the time of treatment failure, were screened using in vitro promastigote assay. The MIL susceptibility of the pre-treatment isolates (N = 24, mean IC50 ± SEM = 3.74 ± 0.38 μM) was significantly higher than that of the post-treatment group (N = 26, mean IC50 ± SEM = 6.15 ± 0.52 μM; P = 0.0006) but was similar in the cured patients (N = 22, mean IC50 ± SEM = 5.58 ± 0.56 μM) and those who failed treatment (N = 28, mean IC50 ± SEM = 4.53 ± 0.47 μM). The pre/post-treatment results thus showed a 2-fold difference, whereas isolated from cured versus failed patients showed a similar susceptibility, suggesting that this higher tolerance is not responsible for MIL-treatment failure. Our work highlights the need for careful monitoring of MIL susceptibility for implementation in national VL elimination programs.

Published: August 2013

We aim to construct a diagnostic model for bacterial coinfection in dengue patients (Dengue Dual Infection Score [DDIS]); 2,065 adult dengue patients (mean age = 41.9 ± 17.2 years, 58.4% male, 83 patients with bacterial coinfection) seen at a university hospital from January of 2005 to February of 2010 were studied. The DDIS was created by assigning one point to each of five risk factors for bacterial coinfection: pulse rate ≥ 90 beats/minute, total white cell count ≥ 6 × 109/L, hematocrit < 40%, serum sodium < 135 mmol/L, and serum urea ≥ 5 mmol/L. The DDIS identified bacterial coinfection (derivation set area under the curve = 0.793, 95% confidence interval = 0.732–0.854; validation set area under the curve = 0.761, 95% confidence interval = 0.637–0.886). A DDIS of ≥ 4 had a specificity of 94.4%, whereas a DDIS of ≥ 1 had a sensitivity of 94.4% for bacterial coinfection. The DDIS can help to select dengue patients for early bacterial cultures and empirical antibiotics.

Published: August 2013

O objetivo deste estudo foi o estabelecimento do estado da arte da pesquisa sobre biblioteca escolar no Brasil, entre 1975 e 2011, buscando identificar: assuntos pesquisados; embasamento teórico-conceitual; metodologias e técnicas utilizadas; resultados e conclusões dos estudos. A metodologia foi análise documental de setenta relatos de pesquisa sobre o tema, separados em seis categorias: biblioteca escolar como espaço de aprendizagem, interação bibliotecário/professor, estudos de usos e usuários, coleção, leitura e pesquisa escolar. Os resultados revelaram que existe consciência da necessidade de se garantir o espaço da biblioteca na escola, considerando-se que ela pode contribuir para a aprendizagem. Há mais estudos na categoria leitura, e tendência no aumento da categoria pesquisa escolar. A necessidade de trabalho conjunto professor/bibliotecário foi reafirmada. Os estudos de uso e usuários ainda estão presos a abordagem tradicional, não conseguindo realizar um diálogo efetivo com a questão pedagógica. As metodologias dos estudos analisados foram em sua maioria qualitativas e o referencial teórico apresentou fragilidade, resultante da pouca clareza de seu uso.

En este trabajo se realiza una investigación exploratoria a partir de la creación de un tesauro para luego proponer una visualización de la terminología francesa de tecnologías de la información y de la comunicación (TIC). Nuestro corpus se ha constituido a partir del «Diccionario de tecnologías de la información y la comunicación», publicado en 2009 por la Comisión General de Terminología y neologismos de Francia, que compila las palabras, frases y definiciones publicadas en el Diario Oficial. La primera visualización de 670 palabras en el que la información se representa mediante nodos y enlaces etiquetados entre estos nodos para mostrar las relaciones semánticas. El tesauro lo hemos construido utilizando un software específico (TemaTres). Una segunda visualización se ha realizado a partir del análisis de redes textuales ART que nos permitió codificar las relaciones entre términos y construir una red. Por último, era una representación de tesauros de la estructura SKOS. Para ello se utilizan los métodos y herramientas de análisis de redes sociales (ARS) que se aplica a los datos de texto, teniendo en cuenta un concepto como una abstracción de la realidad y por lo tanto un reflejo del pensamiento antropológico. Esta visión multifacética revelado a través de métodos mixtos, nos permite ver lo que está aquí la representación de las TIC y su evolución en el tiempo, y finalmente discutir sobre la conveniencia o no de la práctica actual.

Com o dinamismo do novo cenário socioeconômico, definido pela influência das Tecnologias da Informação e Comunicação, provoca-se na sociedade mundial a transição de um modelo ultrapassado, fundamentado no indivíduo para outro, baseado no coletivo, cuja sociedade se coloca numa imensa rede de conexões que interagem entre si. Nesse sentido optar por investir no desenvolvimento de sistemas de informações que possam integrar os mais diversos setores da organização se torna uma necessidade crescente, pois agora são necessárias informações cada vez mais adequadas as suas atividades. Assim, optou-se em analisar os fatores que explicam o uso dos sistemas de informações. Tais fatores relacionam-se ao comportamento e à atitude dos indivíduos diante da tecnologia e do ajuste dela com a tarefa executada. De acordo com a Teoria da Ação Racional, da Teoria do Comportamento Planejado, do Modelo de Aceitação de Tecnologia e do modelo de Adequação entre Tarefa e Tecnologia, chega-se à problemática deste estudo: De que forma os servidores da ESAT estão utilizando o GECAP?

Esta pesquisa analisou a relação de vínculos de comprometimento, entrincheiramento e variáveis sociodemográficas estabelecidas entre servidores públicos e as organizações onde trabalham. O instrumento de coleta de dados foi um questionário contendo itens abertos e fechados incluindo questões referentes ao comprometimento e entrincheiramento organizacionais e dados sociodemográficos. A amostra contou com 400 trabalhadores de nove organizações públicas, situadas em Florianópolis. Os principais resultados apontaram servidores públicos mais comprometidos do que entrincheirados. Dentro deste resultado foram encontradas algumas peculiaridades relevantes, como: indivíduos casados, com filhos e alto grau de responsabilidade financeira, na sua maioria, foram caracterizados com nível de comprometimento e entrincheiramento altos. Percebeu-se, ainda, que quanto maior o nível educacional, maior o nível de entrincheiramento.

O presente artigo buscou apresentar proposições estratégicas para o Polo de Doces de Pelotas, localizado na Região Sul do Estado do Rio Grande do Sul – RS, a partir do mapeamento da rede de valor e da análise do capital social. O Polo de Doces reúne empresas formais e empreendedores informais ligados ao mercado de doces. A pesquisa caracteriza-se como quantitativa e os dados foram coletados por meio de questionários. Como resultado, percebeu-se que na visão de gestores e integrantes do Polo, a rede de valor é formada por: a) clientes: consumidor final, terceiros e revendedores; b) fornecedores: predominando os atacados; c) concorrentes: destacando-se as grandes doçarias, doces industrializados e o comércio informal; d) complementadores: destacou-se a falta conhecimento sobre os complementadores. De modo geral, constatou-se que é necessário obter mais conhecimento sobre os elementos da rede de valor para a geração de vantagens competitivas.

As restrições do orçamento da Marinha do Brasil podem reduzir o volume de serviços de saúde prestados pelo Sistema de Saúde da Marinha, apesar de existir uma maior capacidade de resposta das novas tecnologias de assistência e de aumento do número de usuários contribuintes. Este artigo tem o objetivo de avaliar os hospitais navais da Marinha do Brasil no período 2000-2008 à luz dessas preocupações, com vistas a sugerir melhorias pró-eficiência no uso dos recursos produtivos do Sistema de Saúde da Marinha. Calculada uma fronteira de eficiência de sete hospitais navais com o auxílio da Análise Envoltória de Dados (Data Envelopment Analysis – DEA), os hospitais navais relativamente eficientes foram usados como benchmarks para calcular os planos de operação pró-eficiência dos demais. A hipótese markoviana foi utilizada na análise da transição dos hospitais navais entre os estados de eficiência e de ineficiência no longo prazo.

Abstract. The CMAQ (Community Multiscale Air Quality) us model in combination with observations for INTEX-NA/ICARTT (Intercontinental Chemical Transport Experiment–North America/International Consortium for Atmospheric Research on Transport and Transformation) 2004 are used to evaluate recent advances in isoprene oxidation chemistry and provide constraints on isoprene nitrate yields, isoprene nitrate lifetimes, and NOx recycling rates. We incorporate recent advances in isoprene oxidation chemistry into the SAPRC-07 chemical mechanism within the US EPA (United States Environmental Protection Agency) CMAQ model. The results show improved model performance for a range of species compared against aircraft observations from the INTEX-NA/ICARTT 2004 field campaign. We further investigate the key processes in isoprene nitrate chemistry and evaluate the impact of uncertainties in the isoprene nitrate yield, NOx (NOx = NO + NO2) recycling efficiency, dry deposition velocity, and RO2 + HO2 reaction rates. We focus our examination on the southeastern United States, which is impacted by both abundant isoprene emissions and high levels of anthropogenic pollutants. We find that NOx concentrations increase by 4–9% as a result of reduced removal by isoprene nitrate chemistry. O3 increases by 2 ppbv as a result of changes in NOx. OH concentrations increase by 30%, which can be primarily attributed to greater HOx production. We find that the model can capture observed total alkyl and multifunctional nitrates (∑ANs) and their relationship with O3 by assuming either an isoprene nitrate yield of 6% and daytime lifetime of 6 hours or a yield of 12% and lifetime of 4 h. Uncertainties in the isoprene nitrates can impact ozone production by 10% and OH concentrations by 6%. The uncertainties in NOx recycling efficiency appear to have larger effects than uncertainties in isoprene nitrate yield and dry deposition velocity. Further progress depends on improved understanding of isoprene oxidation pathways, the rate of NOx recycling from isoprene nitrates, and the fate of the secondary, tertiary, and further oxidation products of isoprene.

Abstract. Filter-based PM2.5 samples were chemically analyzed to investigate secondary organic aerosol (SOA) formation from isoprene in a rural atmosphere of the southeastern US influenced by both anthropogenic sulfur dioxide (SO2) and ammonia (NH3) emissions. Daytime PM2.5 samples were collected during summer 2010 using conditional sampling approaches based on pre-defined high and low SO2 or NH3 thresholds. Known molecular-level tracers for isoprene SOA formation, including 2-methylglyceric acid, 3-methyltetrahydrofuran-3,4-diols, 2-methyltetrols, C5-alkene triols, dimers, and organosulfate derivatives, were identified and quantified by gas chromatography coupled to electron ionization mass spectrometry (GC/EI-MS) and ultra performance liquid chromatography coupled to electrospray ionization high-resolution quadrupole time-of-flight mass spectrometry (UPLC/ESI-HR-Q-TOFMS). Mass concentrations of six isoprene low-NOx SOA tracers contributed to 12–19% of total organic matter (OM) in PM2.5 samples collected during the sampling period, indicating the importance of the hydroxyl radical (OH)-initiated oxidation (so-called photooxidation) of isoprene under low-NOx conditions that lead to SOA formation through reactive uptake of gaseous isoprene epoxydiols (IEPOX) in this region. The contribution of the IEPOX-derived SOA tracers to total organic matter was enhanced by 1.4% (p = 0.012) under high-SO2 sampling scenarios, although only weak associations between aerosol acidity and mass of IEPOX SOA tracers were observed. This suggests that IEPOX-derived SOA formation might be modulated by other factors simultaneously, rather than only aerosol acidity. No clear associations between isoprene SOA formation and high or low NH3 conditional samples were found. Positive correlations between sulfate aerosol loadings and IEPOX-derived SOA tracers for samples collected under all conditions indicates that sulfate aerosol could be a surrogate for surface accommodation in the uptake of IEPOX onto preexisting aerosols.

Abstract. This paper discusses cloud simulations aiming at quantitative assessment of the effects of cloud turbulence on rain development in shallow ice-free convective clouds. Cloud fields from large-eddy simulations (LES) applying bin microphysics with the collection kernel enhanced by cloud turbulence are compared to those with the standard gravitational collection kernel. Simulations for a range of cloud condensation nuclei (CCN) concentrations are contrasted. Details on how the parameterized turbulent collection kernel is used in LES simulations are presented. Because of the disparity in spatial scales between the bottom-up numerical studies guiding the turbulent kernel development and the top-down LES simulations of cloud dynamics, we address the consequence of the turbulence intermittency in the unresolved range of scales on the mean collection kernel applied in LES. We show that intermittency effects are unlikely to play an important role in the current simulations. Highly-idealized single-cloud simulations are used to illustrate two mechanisms that operate in cloud field simulations. First, the microphysical enhancement leads to earlier formation of drizzle through faster autoconversion of cloud water into drizzle, as suggested by previous studies. Second, more efficient removal of condensed water from cloudy volumes when a turbulent collection kernel is used leads to an increased cloud buoyancy and enables clouds to reach higher levels. This is the dynamical enhancement. Both mechanisms operate in the cloud field simulations. The microphysical enhancement leads to the increased drizzle and rain inside clouds in simulations with high CCN. In low-CCN simulations with significant surface rainfall, dynamical enhancement leads to a larger contribution of deeper clouds to the entire cloud population, and results in a dramatically increased mean surface rain accumulation. These results call for future modeling and observational studies to corroborate the findings.

Abstract. Emulating the variability that exists in the natural landscape prior to disturbance should be a goal of soil reconstruction and land reclamation efforts following resource extraction. Long-term ecosystem sustainability within reclaimed landscapes can only be achieved with the re-establishment of biogeochemical processes between reconstructed soils and plants. In this study, we assessed key soil biogeochemical attributes (nutrient availability, organic matter composition, and microbial communities) in reconstructed, novel, anthropogenic ecosystems, covering different reclamation treatments following open-cast mining for oil extraction. We compared the attributes to those present in a range of natural soils representative of mature boreal forest ecosystems in the same area of Northern Alberta. Soil nutrient availability was determined in situ with resin probes, organic matter composition was described with 13C nuclear magnetic resonance spectroscopy and soil microbial community structure was characterized using phospholipid fatty acid analysis. Significant differences among natural ecosystems were apparent in nutrient availability and seemed more related to the dominant tree cover than to soil type. When analyzed together, all natural forests differed significantly from the novel ecosystems, in particular with respect to soil organic matter composition. However, there was some overlap between the reconstructed soils and some of the natural ecosystems in nutrient availability and microbial communities, but not in organic matter characteristics. Hence, our results illustrate the importance of considering the range of natural landscape variability and including several soil biogeochemical attributes when comparing novel, anthropogenic ecosystems to the mature ecosystems that constitute ecological targets.
