Managing relational capital for the sustainability of the energy sector in the social media

Various management models have been proposed for intangible business assets in this new digital era. However, these models do not consider the relationships between intangible assets in business management, or their effect. This work has two main objectives: first, to show the effect of intangi-ble assets as expressed in digital media related to energy brands; second, to demonstrate the rela-tionships between the emotions, experiences and attitudes of the audiences. To do so, a novel model of intangibles is proposed and applied to the energy sector using IBEX 35 data. In this sce-nario, we determine that users' experiences extracted from digital environments have significant relationships with one of the most important intangibles in the energy business, namely emotion.Vários modelos de gestão foram propostos para ativos de negócios intangíveis nesta nova era digital. No entanto, esses modelos não consideram as relações entre ativos intangíveis na gestão ou os seus efeitos. Este estudo tem dois objetivos principais: primeiro, mostrar o efeito dos ativos intangíveis expressos nos meios digitais relacionados com as marcas associadas ao setor económico da energia; segundo, demonstrar as relações entre as emoções, experiências e atitudes do público. Para esse efeito, é proposto um novo modelo de gestão de intangíveis aplicado ao setor de energia utilizando dados do IBEX 35. Nesse cenário, concluímos que as experiências dos utilizadores extraídas de ambientes digitais têm relacionamentos significativos com um dos intangíveis mais importantes no negócio de energia, ou seja, a emoção.info:eu-repo/semantics/publishedVersio

Trace-level reuse

Trace-level reuse is based on the observation that some traces (dynamic sequences of instructions) are frequently repeated during the execution of a program, and in many cases, the instructions that make up such traces have the same source operand values. The execution of such traces will obviously produce the same outcome and thus, their execution can be skipped if the processor records the outcome of previous executions. This paper presents an analysis of the performance potential of trace-level reuse and discusses a preliminary realistic implementation. Like instruction-level reuse, trace-level reuse can improve performance by decreasing resource contention and the latency of some instructions. However, we show that trace-level reuse is more effective than instruction-level reuse because the former can avoid fetching the instructions of reused traces. This has two important benefits: it reduces the fetch bandwidth requirements, and it increases the effective instruction window size since these instructions do not occupy window entries. Moreover, trace-level reuse can compute all at once the result of a chain of dependent instructions, which may allow the processor to avoid the serialization caused by data dependences and thus, to potentially exceed the dataflow limit.Peer ReviewedPostprint (published version

Errors in algebraic statements translation during the creation of an algebraic domino

We present a research study which main objective is to inquire into secondary school students´ ability to translate and relate algebraic statements which are presented in the symbolic and verbal representation systems. Data collection was performed with 26 14-15 years old students to whom we proposed the creation of an algebraic domino, designed for this research, and its subsequent use in a tournament. Here we present an analysis of the errors made in such translations. Among the obtained results, we note that the students found easier to translate statements from the symbolic to the verbal representation and that most errors in translating from verbal to symbolic expressions where derived from the particular characteristics of algebraic language. Other types of errors are also identified. KEYWORDS: Algebraic language, domino, errors, translation between representation systems, verbal representation

Tripod-shaped penta (p-phenylene)s for the functionalization of silicon surfaces

In order to obtain nanostructured thin films to be used in biosensor devices, several chemical functionalization methods have been developed, such as Click chemistry or Suzuki carbon-carbon coupling reactions on surfaces.1 With the aim to control the orientation and spacing between grafted functional groups on a surface, tripodal oligo (p-phenylene)s have become the ideal anisotropic adsorbates due to their shape-persistent and self-standing characteristics.2 Here we report the synthesis and characterization of several tripod-shaped oligo(p-phenylene)s molecules with legs composed of five phenylene units, compounds 1, 2 and 3. In these structures, each leg is end-capped with an NH-Boc, NH2 and N3 group, respectively. The functional arm contains an acetylene group. The presented synthesis has as key step the Pd-catalyzed Suzuki cross-coupling reaction. In particular, a iodine derivative from the silicon core molecule reacts with the appropriate tetra(p-phenylene) boron derivative, thus generating the final tripod-shaped structure. The azide end-capped leg in 3 is specifically designed for its covalent incorporation on alkynyl terminated silicon surfaces by an easy and reproducible way. As a preliminary study, we present the alkynyl-functionalized silicon wafers nanostructuration with tripod 3 through the cooper catalyzed alkyne-azide cycloaddition (CuAAC) click reaction.Universidad de Málaga.

Review of progress in the study of the self-perceptions of children with Attention Deficit Disorder with Hyperactivity (ADHD)

El estudio sistemático de las autopercepciones en los niños con Trastorno por Déficit de Atención con Hiperactividad (TDAH) tiene un origen reciente y ha dado lugar a resultados contradictorios. Sin embargo, al incluirse una medida objetiva del desempeño del niño, se encontró que estos niños presentan una tendencia a sobrestimar sus competencias en relación con su desempeño real. Este trabajo se propone presentar una revisión de las investigaciones que abordaron empíricamente el estudio de los mecanismos explicativos en el sesgo positivo ilusorio (SPI) que presentan los niños con TDAH. Se realizó un trabajo de revisión de tipo agregativo. Se consultaron las bases de datos PSYCINFO, ERIC, PUBMED, REDALYC, SCIELO, PUBMED, DIALNET, CLASE Y LILACS. Los términos de búsqueda utilizados fueron: autopercepción, autoevaluación, autoconcepto, autoestima, Trastorno por Déficit de Atención con Hiperactividad, niños y los mismos términos en inglés. La búsqueda mostró que existen evidencias de que este sesgo positivo en sus autopercepciones cumple una función de autoprotección frente a sus habituales fracasos y que está relacionado con las fallas en las funciones ejecutivas asociadas al trastorno. Asimismo, tiene un fuerte impacto en el ajuste psicosocial de estos niños.L'étude systématique de la perception de soi chez les enfants atteints d'un Trouble Téficitaire de l'Attention avec Hyperactivité (TDAH) est d'origine récente et a abouti à des résultats contradictoires. Toutefois, en incluant une mesure objective de la performance, nous avons constaté que ces enfants ont tendance à surestimer leurs compétences par rapport à leur performance réelle. Cet article se propose de présenter un avis de recherche qui s'adresse étudier empiriquement les mécanismes explicatifs de la partialité illusoire positive (SPI) qui ont des enfants atteints de TDAH. Nous avons effectué un examen de type agrégatif de travail. Ont été consultés PSYCINFO, ERIC, PUBMED, REDALYC, SCIELO, PUBMED, DIALNET, CLASE et LILACS. Les termes de recherche utilisés sont: la perception de soi, l'auto, l'estime de soi, le trouble déficitaire de l'attention avec hyperactivité avec soi, les enfants et les mêmes termes en anglais. La recherche a montré qu'il existe des preuves que ce biais positif dans la perception de soi joue un rôle dans l'auto-protection de ses échecs habituels et les échecs associés aux fonctions exécutives associés à la maladie. Il a également un fort impact sur l'ajustement psychosocial de ces enfants.

However, by including an objective measure of child’s performance, it was found that these children have a tendency to overestimate their competences in relation to their real performance. This paper aims to present a review of researches that have empirically studied the mechanisms explaining the positive illusory bias (PIB) in children with ADHD. A summarizing review study was made. PSYCINFO, ERIC, PUBMED, REDALYC, SCIELO, PUBMED, DIALNET, CLASE and LILACS databases were consulted. The search terms used were: selfperception, self-evaluation, self-concept, self-esteem, Attention Deficit Disorder with Hyperactivity, children and the same terms in English. The review showed that there is evidence that this positive bias in their self-perceptions has the role to protect them against their common failure and it is linked with executive dysfunction associated with the disorder. It also has a strong impact on the psychosocial adjustment of these children.Fil: Molina, María Fernanda. Universidad de Buenos Aires. Facultad de Psicología. Instituto de Investigaciones; Argentina.

FIRM DETERMINANTS IN NEW PRODUCT INTRODUCTION: A STUDY THROUGH SURVIVAL ANALYSIS

The literature has broadly discussed the advantages obtained by pioneer firms under the concept of “first mover advantages”. However, less attention has been paid to the study of the factors that determine entry timing. The present paper analyzes the firm’s determinants in the introduction of a product innovation. The results obtained for the Cox regression in the case of the Italian ceramic tiles industry show that technological resources and firm size have a positive and significant influence on the likelihood of the innovation being introduced, while other factors, i.e. financial and marketing resources, have no influence on the adoption of the innovation.survival analysis, determinants of entry timing, resources, first mover advantages.

Trace-level speculative multithreaded architecture

This paper presents a novel microarchitecture to exploit trace-level speculation by means of two threads working cooperatively in a speculative and non-speculative way respectively. The architecture presents two main benefits: (a) no significant penalties are introduced in the presence of a misspeculation and (b) any type of trace predictor can work together with this proposal. In this way, aggressive trace predictors can be incorporated since misspeculations do not introduce significant penalties. We describe in detail TSMA (trace-level speculative multithreaded architecture) and present initial results to show the benefits of this proposal. We show how simple trace predictors achieve significant speed-up in the majority of cases. Results of a simple trace speculation mechanism show an average speed-up of 16%.Peer ReviewedPostprint (published version

Interstitial Lung Diseases in Developing Countries

More than 100 different conditions are grouped under the term interstitial lung disease (ILD). A diagnosis of an ILD primarily relies on a combination of clinical, radiological, and pathological criteria, which should be evaluated by a multidisciplinary team of specialists. Multiple factors, such as environmental and occupational exposures, infections, drugs, radiation, and genetic predisposition have been implicated in the pathogenesis of these conditions. Asbestosis and other pneumoconiosis, hypersensitivity pneumonitis (HP), chronic beryllium disease, and smoking-related ILD are specifically linked to inhalational exposure of environmental agents. The recent Global Burden of Disease Study reported that ILD rank 40th in relation to global years of life lost in 2013, which represents an increase of 86% compared to 1990. Idiopathic pulmonary fibrosis (IPF) is the prototype of fibrotic ILD. A recent study from the United States reported that the incidence and prevalence of IPF are 14.6 per 100,000 person-years and 58.7 per 100,000 persons, respectively. These data suggests that, in large populated areas such as Brazil, Russia, India, and China (the BRIC region), there may be approximately 2 million people living with IPF. However, studies from South America found much lower rates (0.4-1.2 cases per 100,000 per year). Limited access to high-resolution computed tomography and spirometry or to multidisciplinary teams for accurate diagnosis and optimal treatment are common challenges to the management of ILD in developing countries
