A inteligência humana pode ser dividida em dois tipos de inteligência: a cristalizada, a qual se baseia em habilidades adquiridas e aprendizado passado, e a fluida, que se refere à capacidade de relacionar idéias e de resolver novos problemas. Esse estudo explora os efeitos do nível socioeconômico (NSE) no desenvolvimento de habilidades cognitivas fluidas e cristalizadas em crianças. A pesquisa contou com um total de 105 participantes de 6 a 8 anos, pertencentes a três diferentes níveis socioeconômicos (alto, médio e baixo) de acordo com o Critério de Classificação Econômica Brasil (ABEP). Foram recrutadas crianças do primeiro e segundo ano do ensino fundamental de escolas particulares, de bairro e públicas em Salvador. Cada grupo continha 35 participantes equiparados em idade, sexo e ano de escolaridade. Os grupos não diferiram significativamente em aspectos nutricionais, estado emocional, peso ao nascer e tempo de gestação. As crianças foram avaliadas por uma extensa bateria de medidas comportamentais que exploraram a inteligência cristalizada (vocabulário, sintaxe e desempenho acadêmico) e a inteligência fluida (memória operacional e raciocínio indutivo). Os resultados apontaram que crianças inseridas em condições desprivilegiadas (baixo NSE) apresentaram desempenho significativamente pior nas medidas de inteligência cristalizada, quando comparadas às crianças que cresceram em ambiente mais favorável (alto NSE); com tamanho do efeito significativo. As crianças de baixo NSE apresentaram, também, um pior desempenho nos testes de inteligência fluida, que, embora significativo, foram menos expressivos que os efeitos correspondentes nas medidas de linguagem. Este estudo mostra que o crescimento em ambientes de baixo NSE constitui um sério fator de risco para o desenvolvimento cognitivo infantil. Sugere, ainda, que alguns sistemas neurocognitivos são mais sensíveis ao NSE que outros: o sistema de linguagem é fortemente impactado pelo NSE, enquanto a memória operacional e a resolução de conflitos são moderadamente influenciadas. Tais achados relacionados ao perfil neurocognitivo do NSE na infância são essenciais no sentido de testar hipóteses mais específicas sobre mecanismos causais e maximizar o efeito de intervenções. Deste modo, pais e escolas desempenham um papel fundamental em prover um ambiente cognitivo estimulante, a fim de otimizar o desenvolvimento intelectual infantil. [less ▲]

The Industrial Internet should provide means to create ad hoc and loosely coupled information flows between objects, users, services, and business domain systems. However, today’s technologies and products often feed ‘vertical silos’ (e.g., vertical/siloed apps), which inevitably result in multiple and non-interoperable systems. Standardization will play an ever-increasing part in enabling information to flow between such vertically-oriented closed systems. This paper presents recent IoT messaging standards, notably O-MI (Open Messaging Interface) and O-DF (Open Data Format), whose initial requirements were defined for enhanced collaboration and interoperability in product lifecycle management. A first analytical model of the minimal traffic load (in bytes) to fulfil the required/basic standard specifications is then proposed. A smart maintenance use case relying on the first version of the standard reference implementation is developed, based on which our analytical model is applied to evaluate the degree of deviation (w.r.t. the standard specifications) of this reference implementation.

The requirement of calcium ion (Ca(2)(+)) entry for neutrophil NADPH oxidase (NOX2) regulation is clearly established. However, its role in the signaling pathway leading to NOX2 activation is still elusive. 1-oleoyl-2-acetyl-sn-glycerol (OAG) causes an increase in NOX2 activity and has been shown to directly modulate Ca(2)(+) channels unrelated to the well-known store-operated Ca(2)(+) entry (SOCE) mechanism. In our study, we have investigated the potential role of OAG in Ca(2)(+) influx-mediated NOX2 activity in neutrophil-like-differentiated HL-60 cells to further characterize second signals involved in the regulation of NOX2. OAG inhibited fMLF- and thapsigargin-induced Ca(2)(+) entry, a phenomenon that was not restored by protein kinase C (PKC) or PI3K blockade. Addition of OAG resulted in a rapid decrease of maximal intracellular Ca(2)(+) concentration induced by thapsigargin. Both results suggest that OAG has an inhibitory effect, independent of PI3K and PKC, on the regulation of SOCE. In contrast to SOCE inhibition, OAG-induced NOX2 activation was mediated by PKC and PI3K. Our data establish that both kinases exert their effects through the regulation of Rac2 activity. In addition, OAG potentiated the effect of fMLF on the activation of NOX2 and led to a discernible activity of NOX2 upon thapsigargin stimulation. In conclusion, our results demonstrate that an additional PKC- and/or PI3K-dependent signal may act in synergy with Ca(2)(+) influx to trigger NOX2 activation. [less ▲]

To develop a questionnaire with which to measure quality of life (QoL) in patients with knee and hip osteoarthritis (OA). Study Design and Setting: Thirty-two caregivers and 96 OA patients were interviewed individually (using cognitive and face-to-face techniques) and in focus groups. A group of experts working independently at first and then consensually used the interview transcripts to generate a 46-item questionnaire. Results: Analysis of questionnaires completed by 263 patients with hip or knee OA resulted in the exclusion of three items (two because of low reliability and one because of a low response rate). Principal component analysis revealed four factors: physical activity, mental health, social functioning, and social support. A pain dimension was individualized. Preliminary testing showed the reliability of the five dimensions to be satisfactory (intraclass correlation coefficients: 0.70–0.85), construct validity was adequate when correlated with the SF36 (Spearman correlation coefficients: 0.43–0.75), and discrimination was satisfactory. The osteoarthritis knee and hip quality of life questionnaire (OAKHQOL) consists of 43 items in five dimensions and three independent items. Conclusion: TheOAKHQOLis the first specific knee and hipOAquality of life instrument. Its development followed an a priori structured strategy to ensure content validity. It meets psychometric requirements for validity and reliability. [less ▲]

This article reassesses the poetics of homophonic translation in order to come to terms with its (culture-)political effects. In a close reading of poems by Ernst Jandl and Oskar Pastior, Dembeck shows that these authors’ homophonic translations are by no means homogenous in the methods they apply, but rather make use of various, complex strategies of linguistic transformation simultaneously. This constant shifting between strategies enables these poets to make their texts the medium for (culture-)political movements that are, in very different ways, opposed to the presuppositions of monolingualism. Homophonic translation thus proves to be more than just a mere language game without semantic and political impact. [less ▲]

Quels rôles jouent les objets et les dispositifs techniques dans les activités de formation et d'apprentissage ? Comment rendent-ils l'activité collective viable, ou contribuent-ils à la construction des apprentissages ? Le présent ouvrage tente de répondre à ces questions tout en reprenant à nouveaux frais quelques-unes des problématiques actuelles les plus fascinantes des sciences sociales et de l'éducation : la question de l'articulation entre activité individuelle et collective, la négociation collective du sens, la saisie dynamique du cours de l'activité, les réflexions sur les dimensions situées, instrumentées et dynamiques de l'apprentissage. A travers l'analyse d'une dizaine de situations de formation empiriquement attestées, allant de l'école au monde du travail, les contributions analysent les objets dans la dynamique de leur usage. Elles font le point sur les recherches récentes menées à propos des objets dans diverses disciplines et sont autant d'illustrations de la manière dont des approches variées (psychodynamique du travail, approche cours d'action, sociolinguistique interactionnelle, anthropologie cognitive, approches multimodales du discours) peuvent contribuer à illuminer notre compréhension des situations de formation. L'ouvrage s'adresse à toute personne qui s'interroge sur le rôle des objets et du monde matériel dans la vie sociale, l'apprentissage, la formation ou le développement. De manière plus ciblée, il intéresse également les formateurs, chercheurs et/ou praticiens engagés dans la formation des enseignants, dans la formation professionnelle, ou dans la formation des formateurs.

Although various pieces of European secondary law law use the terms "mise en concurrence" ("calling for competition" or "competitive tendering procedure") they provide no definition of the expression "obligation de mise en concurrence" ("obligation to call for competition"). At the very beginning, the author therefore defines what is meant thereby in his thesis, i.e. "a more or less formalized action which a public or a private person has to follow in order to provoke a competition or a contest between potentially interested persons that perform an economic activity, in order to grant an individual advantage to one or several of them". The first part of the work deals with the regime of competitive tendering of the public procurement directives which the Court of Justice has considered "as a whole" to be the "core" of European law on public contracts. First, this part examins the development of the public procurement directives from 1971 on. The author shows that the puzzling evolution of the personal scope of the public procurement directives is guided by the personal scope of European primary law. While considering the remedies directives, the author examines to what extent they introduce requirements beyond the principle of effective judicial protection. While some of their requirements obviously do so, the remedies directives however remain very far from standardizing the means of redress at national level. Due to the member States' judicial autonomy, the compelling force of EU primary law differs from one member State to another. The same applies within the scope of the remedies directives as they let the member States a large degree of autonomy. The author then turns to examine the contribution of the procurement directives 2004/17/CE, 2004/18/CE and 2009/81/CE, their scope of application, as well as the concepts of public works concession and service concession. Various other questions are dealt with in the first part, such as the use of functional interpretation, the power of the European legislator to adopt regulations on public procurement and the impact of the Agreement on Government Procurement (GPA), the Revised GPA and other international agreements. At last the author explores the issue of electronic procurement and the Commission's proposals for replacing the public procurement directives 2004/17/CE and 2004/18/CE and its proposal concerning the award of concession contracts. The second part of of the thesis focuses on primary public procurement law. After having described the origin of the obligation to call for competition under EU primary law which the Court of Justice derives from articles 49 and 56 TFEU as well as from the principles of equal treatment and non-discrimination on the grounds of nationality, the author strives to determine whether this obligation is well-founded. This examination brings to light that the rationale behind the requirement to call for competition under EU primary law is rather fragile. Amongst others, the author comes to the conclusion that the condition of a certain cross-border interest of each public contract individually as a condition for the application of the primary law obligation to call for competition lacks relevance The author then reviews and examines other possible bases for an obligation to call for competition under EU primary law such as the right to good administration, the freedom of enterprise and the right to property, which are protected by the Charter of Fundamental Rights, and the rights guaranteed by the European Convention on Human Rights. Finally, it seems that only article 102 TFEU (abuse of a dominant position) could to a limited extent give rise to an obligation to call for competition. However, once a situation is governed by EU secondary law, it enters the scope of European law. Hence, the principles of equal treatment and of non-discrimination on the grounds of nationality apply even if a situation involves no cross-border interest. If the Court of justice's case law were followed consistently, these principes should lead to require calls for competition in a number of purely internal situations. According to the author, deducing as precise consequences as does the Court of justice from the principal of equal treatment and other fundemental principles can hardly be justified. After that examination, the material rules of public procurement primary law stated by the Court of Justice and the General Court are successively reviewed. The pages that follow are about the exceptions to the obligation to call for competition under the public procurement directives and under primary law, as for instance articles 51 and 52 TFEU, overriding reasons of general interest and article 106, paragraph 2, TFEU. The author thereafter addresses the question whether primary law applies within the scope of secondary law. He comes to the conclusion that it does even when secondary law represents an exhaustive body of rules. Notwithstanding some ambiguous judgements of the Court of justice there is no support for the doctrine of priority of application of secondary law in the Court's case law. In what follows, the author tries to answer the question whether, in order to stay consistent with the case law developed in the wake of Telaustria, the obligation to call for competition which the case law of the Court of Justice requires for public works, service and supply contracts ought to be extended to other operations (sale or lease of real estate, design contests outside the scope of the public procurement directives, employment contracts, subsidised contracts awarded by private entities outside the scope of the public procurement directives, grants, …). The end of the second part deals with the personal scope of the primary law of public procurement which corresponds to that of EU primary law. The rules concerning State aid are addressed in detail in the third part of the thesis. The examination in that part shows that the public procurement directives, the primary law of public procurement and the EU state aid rules apply cumulatively. The EU State aid rules require efficency when awarding public contracts. Nevertheless, in order to avoid the categorization as State aid, a call for competition is never formally required. The Commission however insists on calls for competition in order to declare certain aids compatible with the internal market. Aids include by definition an advantage for their recipients. This remains true even though an aid has been authorised by the Commission pursuant to article 107, paragraphe 3, TFEU. Given the very broad scope the Court of Justice gives to the freedom of establishment and the free movement of services, aid measures give generally rise to obstacles to the freedom of establishment and the free movement of services. At the risk of rendering article 107, paragraph 3, TFEU unnecessary, the fact that an aid measure impedes the fundamental freedoms of the internal market should therefore not prevent the Commission to declare it compatible with the internal market. This applies in particular to aids consisting in the award of a public contract that is covered only by EU primary law. That solution seems however excluded for public contracts within the scope of the public procurement directives. The Commission has adopted a broad concept of what is an "advantage" in the sense of the State aid rules. This leads the Commission to consider certain grants for environmental protection as State aid measures even though it may be difficult to dectect any kind of advantage. The Commission claims to control these measures in accordance with the rules of State aid control. On that occasion the Commission tends to make its consent subject to a call for competition in order to identify the projects that will be subsidized. A broad approach of the concept of undertaking leads to class as State aid various public infrastructure investments insofar they do not satisfy the private investor test. The Commission tends to make its consent to these investments subject to calls for competition. Such is notably the case regarding public investments in broadband network facilities. In the fourth part, the author examines a variety of secondary legislation imposing calls for competition other than the public procurement directives. These texts cover a wide range of areas and provide for competitive awards of various form and diverse content. Sometimes a requirement for competitive tendering is overtly expressed. At other times, it is implicit, indirect or just inchoate. Some advantages are awarded without a genuine competition or without any competition at all. Directive 2012/34/CE establishing a single European railway area for instance sets principles for the allocation of "infrastructure capacity" (i.e the right to use a railway network). It does not employ such terms as "calling for competition". Where the infrastructure capacity is insufficient it has to be allocated in a fair and non discriminatory manner. The fee for using the railway network cannot be used as an award criterion. In some areas, competition in terms of price is the very basis of the system. This is true for the greenhouse gas emissions trading scheme. It happens that competitive assignment occurs incidentally and in a non compulsory way as in the case of the milk quota regime. In other cases, e.g. certain situations covered by the internal electricity market regime, the system excludes calls for competition whereas they should be required according to primary procurement law principles. Under still other circumstances, i.e. the award of public service contracts for public passenger transport services, competitive tendering only needs to be strictly complied with after a transitional period. This can hardly be reconciled with the principles of primary procurement law. In some cases the rules in place are such, for example when awarding the universal postal service, that it seems doubtful that a competitive bidding following objective and transparent criteria is really possible. The European greenhouse gas emissions trading scheme relies on auctions for the allocation of gaz emission authorisations. At first, it does so to a limited extent. Such authorisations, called "allowances", are freely transferable. Thus a reallocation of allowances according to market mechanismes is made possible. The author sheds light on some major inconsistencies of the greenhouse gas emission trading scheme. The late deadline for surrendering allowances gives rise for several years to a surplus of allowances over the greenhouse gas emissions considered in the scheme. On the other hand, the costs for same amounts of greenhouse gas emitted at the same time may vary. This gives rise to a problem of equality. The author comes to the conclusion that the scheme has little capacity to reach the objective of reducing greenhouse gas emissions at least cost to the economy. The designation of the universal postal service providers implies to lay down rules as to how the net cost of the universal service is to be calculated, as well as to define appropriate award criteria. These steps face considerable difficulties. A similar situation can be found in other areas such as electronic communications and electricity or natural gas transmission or distribution systems. In the latter case, the risk of a change of transmission or distribution tariffs due to decisions of national regulatory authorities leaves the competitors in the dark on a crucial point. The legislation regarding the internal electricity market and the internal gaz market puts the transmission and distribution system operators in a position very similar to that of service or public works concession holders. In some cases the principles which underlie these schemes exclude competitive tendering as required by primary procurement law. The networks being freely transferable, ownership of networks and hence, in principle, their operators are determined by private market mechanismes mainly through the level of the proposed sales price. This is not consistent with the principles of primary procurement law stated by the Court of Justice (advertising requirements, award criteria linked to the subject matter of the contract, ...) . Neither does it seem compatible with these principles that the development of the networks belongs automatically to the transmission and distribution system operators. The assessment of conformity of secondary legislation with primary law is less strict than the conformity assessment of national law. The Court of Justice has allowed the European legislator a wide margin of discretion when establishing the internal market and seems to have tacitely acknowledged a form of conformity presumption of secondary law. Save in exceptional cases, it seems unlikely that the Court will put into question secondary law regimes differing from primary law procurement rules. Thus, the European legislator may adopt such solutions without incurring major legal risks. [less ▲]
