Governança corporativa: um estudo da relação entre custo de agência e conselho de administração nas empresas listadas no IBrX-100

A teoria da agencia evidencia o conflito de interesse, no qual os gestores detem informacoes privilegiadas acerca do negocio, podendo as utilizar para beneficio proprio, em detrimento do principal. Na tentativa de combater a assimetria informacional, as empresas investem cada vez mais em praticas de governanca corporativa, dentro desse instrumento encontra-se o conselho de administracao, cuja funcao e importante para a excelencia da gestao e o alinhamento dos interesses. Neste sentido, o objetivo dessa pesquisa e verificar quais caracteristicas do conselho de administracao tem relacao inversa aos custos de agencia das empresas listadas no IBrX-100. As caracteristicas do conselho estudadas foram: Tamanho, Independencia e a Dualidade de Cargos. No que tange ao custo de agencia, este foi baseado em medidas de desempenho como Taxa de Retorno do Ativo (TRA) e a relacao de despesas e receita total de vendas (RDV). A amostra foi composta 77 empresas (de diversos setores) listadas na IBrX-100 da BM&FBOVESPA, no periodo de 2010 a 2014. Utilizou-se da tecnica de analise de conteudo nos demonstrativos financeiros e no formulario de referencia das empresas, sendo os dados verificados em painel. Os resultados encontrados demonstraram que o tamanho do conselho, a independencia e a dualidade de cargos possuem relacoes significativamente negativas com os custos de agencia, sendo este calculado por meio do TRA ou pela RDV, ou seja, quanto maior o tamanho, independencia e dualidade do conselho de administracao, menores serao os custos de agencia.
Predictive current control of saturated cross-coupled permanent magnet synchronous machines

Highly utilized permanent magnet synchronous machines show magnetic saturation and cross-coupling effects. These phenomena are described by nonlinear differential equations and make feedback current control of the machine challenging. State of the art current control methods usually ignore these effects and hence do not produce optimal results in transient operation or in operation at the inverter voltage limit. Therefore, this paper presents a method to design a current controller taking into account saturation and dynamic cross-coupling. Feed forward calculation of transient quantities in realtime enables complete decoupling and dead-beat behavior which is experimentally validated by test bench measurements. With this approach, strongly nonlinear, highly utilized synchronous machines can be successfully controlled achieving best control quality in all operational conditions.
A Longitudinal Analysis of Gaming- and Non-Gaming-Related Friendships and Social Support among Social Online Game Players

ABSTRACT Research examining online games often focuses on their potential to negatively impact players. One of the most common concerns is that playing online with others can displace offline relationships and, consequently, detrimentally affect one’s level of “offline” social support. However, there has been little empirical evidence supporting these causal claims. The current study addresses this by outlining a longitudinal analysis between gaming- and non-gaming-related friendships and social support among a representative sample of social online players (i.e., people who play online video games with others). The results indicate that social online video game play with online or offline friends is not related to perceived social support, positively or negatively, cross-sectionally or longitudinally. Taken together, these results dispute the long-held claims of the social displacement hypothesis and instead suggest that social online video game play does not have negative real-world consequences on players’ offline friendships or levels of offline social support.
On the Integration of Need–related Autobiographical Memories among Late Adolescents and Late Adults: The Role of Depressive Symptoms and Self–congruence

Within self–determination theory, integration denotes the process through which people accept past and present experiences and harmonize these experiences within their sense of self. We investigated associations between indicators of successful and poor integration of need–related memories and memory–related affect. We also examined the role of depressive symptoms and self–congruence as antecedents of these indicators. Moreover, we investigated whether late adults, compared with late adolescents, were better capable of integrating need–frustrating memories through higher levels of self–congruence. Participants were 132 late adolescents (Mage = 17.83) and 147 late adults (Mage = 76.13), who reported on their level of depressive symptoms and self–congruence. Next, participants generated a need–satisfying and need–frustrating memory and reported on the memories‘ integration (in terms of acceptance, connection and rumination) and associated affect. Whereas depressive symptoms related mainly to the poor integration of need–frustrating memories, self–congruence related positively to the integration of both need–satisfying and need–frustrating memories. In turn, integration was related to more positive and less negative affect. Late adults scored higher than late adolescents on the integration of need–frustrating memories, an effect that was partly accounted for by late adults‘ elevated self–congruence. Results suggest that self–congruence, depressive symptoms and age play a role in the integration of need–based autobiographical memories.

Estratégia de marketing criativo e execução efetiva sobre o seu desempenho no Paquistão

The purpose of the current research is to determine the influence of creative marketing strategies and effective execution on business unit performance. Moreover, strategic orientation and environmental uncertainty are used as moderating variables. Data are collected from 368 key informants working in Fast-Moving Consumer Goods (FMCG), banking, pharmaceutical, chemical, insurance, and engineering industries using a multi-stage random sampling technique. Factor analysis and multiple hierarchal regressions are used to test the study hypotheses. The results indicate that creative marketing strategy and effective execution are positively associated with business performance. Moreover, environmental uncertainty and strategic orientation play a moderating role in the above relationships.
Quantum stress tensor in the three-dimensional black hole.

The quantum stress tensor 〈${\mathit{T}}_{\mathrm{\ensuremath{\mu}}\ensuremath{\nu}}$〉 is calculated in the (2+1)-dimensional black hole found by Banados, Teitelboim, and Zanelli. The Green's function, from which 〈${\mathit{T}}_{\mathrm{\ensuremath{\mu}}\ensuremath{\nu}}$〉 is derived, is obtained by the method of images. For the nonrotating black hole, it is shown that 〈${\mathit{T}}_{\mathrm{\ensuremath{\mu}}\ensuremath{\nu}}$〉 is finite on the event horizon, but diverges at the singularity. For the rotating solution, the stress tensor is finite at the outer horizon, but diverges near the inner horizon. This suggests that the inner horizon is quantum mechanically unstable against the formation of a singularity.
Detection of Anammox Activity and 16S rRNA Genes in Ravine Paddy Field Soil

An anammox assay involving a 15N tracer and gas chromatography-mass spectrometry revealed that the potential anammox activity accounted for 1 to 5% of total N2 production in a ravine paddy field, Japan. Among four 4-cm-deep layers, the top layer showed the highest activity. Clone libraries showed that the DNA in the top layer contained sequences related to those of Candidatus ‘Brocadia fulgida’, Ca. ‘B. anammoxidans’, and Ca. ‘Kuenenia stuttgartiensis’. These results suggest that a specific population of anammox bacteria was present in paddy soils, although a small part of dinitrogen gas was emitted from the soil via anammox.
Cleaning the spurious links in data

Data quality problems can arise from abbreviations, data entry mistakes, duplicate records, missing fields, and many other sources. These problems proliferate when you integrate multiple data sources in data warehousing, federated databases, and global information systems. A newly discovered class of erroneous data is spurious links, where a real-world entity has multiple links that might not be properly associated with it. The existence of such spurious links often leads to confusion and misrepresentation in the data records representing the entity. Although the data set is well known for its high-quality bibliographic information, collecting and maintaining the data from diverse sources requires enormous effort. Errors, including spurious links, are inevitable. To solve this problem, we use context information to identify spurious links. First, we identify data records that contain potential spurious links. We then determine the set of attributes that constitute each record's context. Experiments with three real-world databases have demonstrated that our approach can accurately identify spurious links. Comparing context information between data records can help solve the data quality problem of spurious links-that is, multiple links between data entries and real-world entities.
Re-thinking corporate entrepreneurship and venturing: a case study in the Italian food industry

The study of Corporate Entrepreneurship (CE) is gaining increasing interest within the field of Entrepreneurship. Much research has been carried out, mainly focusing on identifying determinants and outcomes of CE. Scholars suggest that the term “corporate entrepreneurship” encompasses two types of phenomena: corporate venturing (CV) and strategic renewal. CV is seen as a way in which firm-level entrepreneurship is expressed. Nevertheless, a combination of empirical observation and theoretical reflections has led us to reconsider the phenomenon of CV. We carried out a case study analysis of a well known Italian company operating in the food industry: Riso Gallo. Past research on the organizational determinants of firm-level entrepreneurship investigated only those factors strictly related to the internal environment of the company, overlooking those organizational aspects that go beyond the current firm boundaries. The case study suggests that CV can be seen not only as an effect of CE but also as an organizational arrangement that enhances entrepreneurship in companies.
Differences in processing times for distractors and pictures modulate the influence of distractors in picture–word interference tasks

ABSTRACT In the picture–word interference paradigm, participants name pictures while ignoring a distractor word. When targets and distractors share phonemic and/or graphemic content, naming latencies are shorter than when there is no overlap between the two words. This study examines the hypothesis that the facilitation effect is modulated by differences in the time it takes participants to encode the picture name and process the distractor. Participants named pictures while ignoring distractors that either shared a phonological/orthographical syllable with the target word or were unrelated to that word. Response latencies during the naming of the distractors were collected and used as a measure of distractor processing time. The facilitation effect in picture naming was modulated by differences in response times between the picture and word naming tasks. This finding complements previous studies in showing that picture naming processes in the picture–word interference paradigm are influenced by the time course of distractor processing.
The Resilience Compass: How Mindset, Skills-Development, Self-Compassion, Service, and Community Empower Actors to Bounce Back, Reclaim Their Passion, and Live Their Purpose

Actors often describe their vocation as a passion, a calling, or even a purpose. However, the very nature of a career as an actor is rife with rejection, a lack of agency, and income instability. Such strong identification with their vocation may threaten an actor’s self-concept in the face of so much adversity. Many actors become frustrated, sometimes to the point of giving up, because the gatekeepers (agents, casting directors, network executives, etc.) decide whether they get to exercise their passion or fulfill their purpose by actually working in their chosen profession. While the body of research on resilience is robust, there have been virtually no studies on the application of resilience training to this particular ‘at risk’ population. Based on the theory, research, and practice of positive psychology, this paper proposes a resilience model for actors incorporating 1) a resilience mindset and toolkit, 2) self-compassion, 3) community, and 4) using one’s talent in service to others. It is hypothesized that this combination will enhance resilience, build a strong community, bolster actors’ well-being, and provide a volitional pathway to exercise one’s passion and purpose without sacrificing vulnerability. This is the foundation of The Resilience Compass.
Single-Neuron NMDA Receptor Phenotype Influences Neuronal Rewiring and Reintegration following Traumatic Injury

Alterations in the activity of neural circuits are a common consequence of traumatic brain injury (TBI), but the relationship between single-neuron properties and the aggregate network behavior is not well understood. We recently reported that the GluN2B-containing NMDA receptors (NMDARs) are key in mediating mechanical forces during TBI, and that TBI produces a complex change in the functional connectivity of neuronal networks. Here, we evaluated whether cell-to-cell heterogeneity in the connectivity and aggregate contribution of GluN2B receptors to [Ca2+]i before injury influenced the functional rewiring, spontaneous activity, and network plasticity following injury using primary rat cortical dissociated neurons. We found that the functional connectivity of a neuron to its neighbors, combined with the relative influx of calcium through distinct NMDAR subtypes, together contributed to the individual neuronal response to trauma. Specifically, individual neurons whose [Ca2+]i oscillations were largely due to GluN2B NMDAR activation lost many of their functional targets 1 h following injury. In comparison, neurons with large GluN2A contribution or neurons with high functional connectivity both independently protected against injury-induced loss in connectivity. Mechanistically, we found that traumatic injury resulted in increased uncorrelated network activity, an effect linked to reduction of the voltage-sensitive Mg2+ block of GluN2B-containing NMDARs. This uncorrelated activation of GluN2B subtypes after injury significantly limited the potential for network remodeling in response to a plasticity stimulus. Together, our data suggest that two single-cell characteristics, the aggregate contribution of NMDAR subtypes and the number of functional connections, influence network structure following traumatic injury.
COMPARISON AND CHARACTERIZATION OF NUCLEAR ISOLATION PROCEDURES AS APPLIED TO CHICK OVIDUCT

A number of methods for the preparation of chick oviduct nuclei have been compared. Nuclei have been isolated in hypertonic sucrose and citric acid and the product has been characterized with respect to cleanliness, ultrastructure, RNA polymerase activity, RNA integrity, and chromatin composition. The study demonstrates that the choice of oviduct nuclear isolation procedure will depend markedly on the purpose for which the nuclei are required. Thus, nuclei prepared entirely in high-molarity sucrose retain the highest levels of RNA polymerase. Those prepared rapidly in the presence of citric acid retain nuclear RNA in an essentially undegraded state. Finally, a bulk preparation is described which, because of its adaptability and high yield of morphologically intact nuclei using large amounts of tissue, is ideal for use in preparing chromatin. Conditions are described by which isolated nuclei can be stored for up to 6 months and retain their morphology, chemical characteristics, and RNA polymerase activity.
Antisense Treatment for Myasthenia Gravis

Acetylcholinesterase pre‐mRNA is susceptible to alternative splicing. Myasthenia gravis has been shown to be associated with the expression of the readthrough transcript (AChE‐R), which, unlike the normal “synaptic” transcript (AChE‐S) is not tethered to the post‐synaptic membrane, but is a soluble monomer in the synaptic cleft. In rats with experimental autoimmune myasthenia gravis (EAMG), inhibition of production of AChE‐R using antisense is associated with a significant reduction in synaptic expression of AChE‐R mRNA and protein, with improved muscle strength and stamina and increased survival. Synaptic AChE does not appear to be significantly affected by the induction of EAMG or treatment with antisense to AChE‐R. Monarsen (EN101) is a synthetic 20‐base antisense oligodeoxynucleotide directed against the human AChE gene. It is modified to achieve stability for oral administration. Sixteen patients with seropositive myasthenia gravis who were responsive to pyridostigmine were withdrawn from it and treated with Monarsen. Fourteen patients experienced a clinically significant response. In some, the improvement was dramatic. Although the dose of pyridostigmine was not optimized before the study, the majority of responders achieved better Quantitative Myasthenia Gravis scores than on pyridostigmine. The response of an individual muscle group to Monarsen was related to the degree of deterioration following the withdrawal of pyridostigmine. Cholinergic side effects were conspicuous by their absence. Monarsen is now being investigated in a phase II study.
Observational Study: Familial Relevance and Oncological Significance of Revised Bethesda Guidelines in Colorectal Patients That Have Undergone Curative Resection

AbstractAmsterdam criteria for the hereditary nonpolyposis colorectal cancer (HNPCC) exclude most suspect cases of possible hereditary colorectal cancer (CRC). By contrast, revised Bethesda guidelines excessively broaden the disease spectrum. The aim of this study is to retrospectively evaluate the cliniciopathilogical characteristics of patients fulfilling the revised Bethesda guidelines and to review the efficacy and limitations of the revised guidelines.This retrospective study enrolled 3609 patients who underwent curative surgery for primary CRC. Patients were classified into the Bethesda group or the control group according to whether they fulfilled the revised Bethesda guidelines. Patients were further categorized when they fulfilled a minimum of 2 items of the revised guidelines. Individual items were analyzed for deficient mismatch repair (d-MMR). The median follow-up was 82.9 (interquartile range, 72–101) months. Patients in the Bethesda group were younger and had a higher rate of reduced mismatch repair (MMR) protein expression, microsatellite instability, and right colonic involvement (all P < 0.001) than the control group. As a predictor of d-MMR, the revised Bethesda guidelines showed a sensitivity of 63.0% and a specificity of 72.6%. Items 1 and 2, respectively, or the item pair 1 and 2, were independent predictors of d-MMR (all P < 0.001). Patients fulfilling the Bethesda guidelines showed clinicopathological features of HNPCC.The revised Bethesda guidelines appear to be a competent predictor of d-MMR. Specifically, items 1 and 2 are significant predictors of d-MMR and may be relevant to the application of the revised Bethesda guidelines.
Self-Reported Memory for Abuse Depends Upon Victim-Perpetrator Relationship

Abstract We present preliminary results from the Betrayal Trauma Inventory (BTI) testing predictions from betrayal trauma theory (Freyd. 1994, 1996, in press) about the relationship between amnesia and betrayal by a caregiver. The ? assesses trauma history using behaviorally defined events in the domains of sexual, physical, and emotional childhood abuse, as well as other lifetime traumatic events. When participants endorse an abuse experience, follow-up questions assess a variety of factors including memory impairment and perpetrator relationship. Preliminary results support our prediction that abuse perpetrated by a caregiver is related to less persistent memories of abuse. This relationship is significant for sexual and physical abuse. Regression analyses revealed that age was not a significant predictor of memory impairment and that duration of abuse could not account for the findings.
Cultivating Self-Compassion in Trauma Survivors

Most of us treat ourselves rather unkindly when bad things happen to us. Rather than offering ourselves the same sympathy and support we would give to a loved one, we tend to criticize ourselves (“What’s the matter with you! ”), we hide from others or ourselves in shame (“I’m worthless”), and we get stuck in our heads trying to make sense of what happened to us (“Why me? ”). And when very bad things happen, we attack ourselves from two directions saying, for example, “I’m bad because I was abused” and “I was abused because I’m bad. ” If we do not numb ourselves through dissociation, we may try drugs, alcohol, or self-injury. And no matter how much we wish to get out of our heads and get on with our lives, we find ourselves locked in a struggle with intrusive memories, nightmares, and flashbacks. Such reactions make our suffering persist and even amplify it, but they’re not our fault. They’re how we’re wired (Gilbert, 2009a). When we feel threatened by external danger, our survival often depends on our capacity to fight, flee, or freeze. But when we’re threatened internally by intense emotions such as dread or shame, the fight–flight–freeze response turns into an unholy trinity of self-criticism, self-isolation, and self-absorption. Fortunately, we also have a hardwired capacity to respond to our own
On list-decoding schemes for punctured Reed-Solomon, Gabidulin and subspace codes

Punctured Reed-Solomon (RS) and Gabidulin (G) codes over the field Fqm with locators from the subfield Fq can be represented as interleaving of m correspondent codes over the subfield Fq or can be considered as virtual interleaving of m correspondent codes over the field Fqm. Using an interpolation-based list decoder, m-interleaved or virtually interleaved codes can be decoded up to the same radius mm+T (d - 1), where d is the code distance in the corresponding metric. An explicit root-finding system for the virtual interleaved decoder that can be solved efficiently over Fq is presented. We show that correspondent decoders over the subfield Fq and the field Fqm are equivalent and conclude that in practice one should use a decoder over the subfield since it has less complexity. For m-interleaved codes over Fq a decoding parameters is introduced that allows to control the decoding radius vs. list size trade off.
