Honorários, serviços fora da área de auditoria e independência do auditor : evidências nas companhias abertas listadas na BM&FBovespa

O presente trabalho possui o objetivo de identificar os determinantes dos honorários e serviços fora da área de auditoria, bem como avaliar se a prestação destes serviços conjuntamente com a auditoria das demonstrações financeiras afeta a independência dos auditores externos das companhias abertas brasileiras negociadas na BM&FBovespa. A amostra contempla um total de 180 empresas não financeiras observadas no período de 2010 a 2012. Os resultados indicam que as proxies para esforço e risco elevam os honorários de auditoria, enquanto a governança corporativa apresentou tanto o efeito demanda (elevam os honorários) quanto o efeito risco (reduzem os honorários) dependendo da proxy observada. No que tange a contratação de serviços fora da área de auditoria foi constatado que empresas com maior necessidade de monitoramento e com comitês de auditoria demandam esses serviços, embora o conselho fiscal iniba a contratação dos mesmos. Por fim, as evidências indicam que a prestação de serviços fora da área de auditoria não afeta a independência do auditor. Estes resultados são mantidos mesmo quando observada a probabilidade de ocorrência da modificação no parecer da auditoria relacionada à violação da premissa de continuidade da firma (Going Concern Opinion). Os testes adicionais realizados confirmam a manutenção da independência do auditor, inclusive quando observado o tipo de auditor (não Big4), expectativa de ganhos futuros relacionados a serviços fora da área de auditoria adicionais, empresas consideradas ressalváveis, bem como o efeito de melhores práticas de governança corporativa.

Auditoria na UE : Avaliação dos riscos do auditor: Relatório de estágio

No sentido de uma aprendizagem e de um conhecimento mais aprofundado sobre a actividade da auditoria na sua vertente interna e externa, áreas de significativo interesse para um profissional da administração pública, foi este Relatório de Estágio fectuado na Universidade de Évora, integrando a equipa de auditoria interna desta Instituição e acompanhando os trabalhos desenvolvidos pela mesma. Este trabalho visa, com particular ênfase chamar a atenção para a crescente importância da Auditoria Interna, e dos riscos associados a esta actividade, recorrendo-se ainda a práticas e procedimentos inerentes à Auditoria Externa, uma vez que entre as mesmas se encontram pontos comuns relevantes para fundamento das acções desenvolvidas. A Auditoria Interna, numa visão actual do seu funcionamento, centra a sua atenção nas actividades que a Organização exerce. É neste sentido que este trabalho de estágio deve proporcionar: - uma reflexão sobre a importância do planeamento dos trabalhos; - um levantamento e identificação dos riscos de um auditor; - uma definição dos riscos da auditoria e da materialidade. De forma a que no decorrer do mesmo seja possível interpretar as normas técnicas e directrizes de auditoria, aplicando-as na execução dos trabalhos. Estes irão desenvolver-se incidindo sobre as normas internacionais de auditoria (ISA), ISA315 - Compreensão da Entidade e do Seu Ambiente e Avaliar os Riscos de Distorção Material e ISA 330 - Os Procedimentos do Auditor em Resposta a Riscos Avaliados. /ABSTRACT: ln order to get a deeper knowledge about the activity of internal auditing, a topic of significant interest for a public administration professional, the output of this work is an Internship Report realized in the University of Évora, integrating the internal auditing team of this institution and observing the work developed by this team. This work aims to draw attention to the increasing importance of Internal Auditing and to the risks associated with this activity, using practices and procedures of External Auditing, since there are important common issues between the two types of auditing, which are relevant for the tasks under analysis. The current approach in Internal Auditing is centered in the activities that the Organization performs. It is in this sense that this internship intends to: provide a reflection on the importance of planning, identify the risks of an auditor, define auditing risks and materiality. It is also intended that during the internship there is the opportunity to interpret the technical auditing norms and directives and to apply them in the execution of auditing tasks. The work will be developed considering the international standard for Auditing (ISA), ISA 315 Obtaining and understanding of the entity and its environment and assessing the risks of material misstatement e ISA 330- Materiality in Planning and Performing an Audit.

Preservation Of The External Jugular Vein In Bilateral Radical Neck Dissections: Technique In Two Cases And Review Of The Literature.

Context. The possibility of cephalic venous hypertension with the resultant facial edema and elevated cerebrospinal fluid pressure continues to challenge head and neck surgeons who perform bilateral radical neck dissections during simultaneous or staged procedures. Case Report. The staged procedure in patients who require bilateral neck dissections allows collateral venous drainage to develop, mainly through the internal and external vertebral plexuses, thereby minimizing the risks of deleterious consequences. Nevertheless, this procedure has disadvantages, such as a delay in definitive therapy, the need for a second hospitalization and anesthesia, and the risk of cutting lymphatic vessels and spreading viable cancer cells. In this paper, we discuss the rationale and feasibility of preserving the external jugular vein. Considering the limited number of similar reports in the literature, two cases in which this procedure was accomplished are described. The relevant anatomy and technique are reviewed and the patients' outcomes are discussed. Conclusion. Preservation of the EJV during bilateral neck dissections is technically feasible, fast, and safe, with clinically and radiologically demonstrated patency.

Combined External Pressure And Cu-substitution Studies On Bafe2as2 Single Crystals.

We report a combined study of external pressure and Cu-substitution on BaFe2As2 single crystals grown by the in-flux technique. At ambient pressure, the Cu-substitution is known to suppress the spin density wave (SDW) phase in pure BaFe2As2(TSDW ≈ 140 K) and to induce a superconducting (SC) dome with a maximum transition temperature [Formula: see text]. This [Formula: see text] is much lower than the Tc ∼ 15-28 K achieved in the case of Ru, Ni and Co substitutions. Such a lower Tc is attributed to a Cu(2+) magnetic pair-breaking effect. The latter is strongly suppressed by applied pressure, as shown herein, Tc can be significantly enhanced by applying high pressures. In this work, we investigated the pressure effects on Cu(2+) magnetic pair-breaking in the BaFe2-xCuxAs2 series. Around the optimal concentration (xopd = 0.11), all samples showed a substantial increase of Tc as a function of pressure. Yet for those samples with a slightly higher doping level (over-doped regime), Tc presented a dome-like shape with maximum Tc ≃ 8 K. Remarkably interesting, the under-doped samples, e.g. x = 0.02 display a maximum pressure induced Tc ≃ 30 K which is comparable to the maximum Tc's found for the pure compound under external pressures. Furthermore, the magnetoresistance effect as a function of pressure in the normal state of the x = 0.02 sample also presented an evolution consistent with the screening of the Cu(2+) local moments. These findings demonstrate that the Cu(2+) magnetic pair-breaking effect is completely suppressed by applying pressure in the low concentration regime of Cu(2+) substituted BaFe2As2.

Internal and external time conflicts in adolescents: sleep characteristics and interventions

Daytime fatigue and lack of sleep seem to increase throughout adolescent years. Several environmental, psychological, and biological factors have been associated with the development of sleep across adolescence. The aim of the present article is to summarize these factors and to give examples of various outcomes in sleep patterns among adolescents studied in different cultural settings. It is obvious from earlier work that many adolescents have displaced circadian rhythms and lack of adaptation to school hours due to an early school start or additional burdens for work. Several interventions have aimed to help the adaptation process by supporting sleep processes and changing scheduling, in this way promoting classroom alertness. In summary, adolescents worldwide shorten their sleep due to schoolwork hours and additional work, especially by disturbing their sleep due to circadian misalignment

Hard thermal loops in static external fields

We examine, in the imaginary-time formalism, the high temperature behavior of n-point thermal loops in static Yang-Mills and gravitational fields. We show that in this regime, any hard thermal loop gives the same leading contribution as the one obtained by evaluating the loop integral at zero external energies and momenta.

Classical noncommutative electrodynamics with external source

In a U(1)(*)-noncommutative gauge field theory we extend the Seiberg-Witten map to include the (gauge-invariance-violating) external current and formulate-to the first order in the noncommutative parameter-gauge-covariant classical field equations. We find solutions to these equations in the vacuum and in an external magnetic field, when the 4-current is a static electric charge of a finite size a, restricted from below by the elementary length. We impose extra boundary conditions, which we use to rule out all singularities, 1/r included, from the solutions. The static charge proves to be a magnetic dipole, with its magnetic moment being inversely proportional to its size a. The external magnetic field modifies the long-range Coulomb field and some electromagnetic form factors. We also analyze the ambiguity in the Seiberg-Witten map and show that at least to the order studied here it is equivalent to the ambiguity of adding a homogeneous solution to the current-conservation equation.

An external focus of attention results in greater swimming speed

We examined effects of attentional focus on swimming speed. Participants` task was to swim one length of a pool (16 m) using the front crawl stroke. In Experiment 1, intermediate swimmers were given attentional focus instructions related to the crawl arm stroke or the leg kick, respectively. Participants were instructed to focus on ""pulling your hands back"" or ""pushing the instep down"" (internal focus), or on ""pushing the water back/down"" (external focus), respectively. Swim times were significantly shorter with an external focus. In Experiment 2, a control condition was included. Times were significantly faster in the external focus compared with both the internal focus and control conditions. These findings have implications for enhancing performance in swimming.

Fuzzy risk index for power transformer failures due to external short-circuits

A novel methodology to assess the risk of power transformer failures caused by external faults, such as short-circuit, taking the paper insulation condition into account, is presented. The risk index is obtained by contrasting the insulation paper condition with the probability that the transformer withstands the short-circuit current flowing along the winding during an external fault. In order to assess the risk, this probability and the value of the degree of polymerization of the insulating paper are regarded as inputs of a type-2 fuzzy logic system (T2-FLS), which computes the fuzzy risk level. A Monte Carlo simulation has been used to find the survival function of the currents flowing through the transformer winding during a single-phase or a three-phase short-circuit. The Roy Billinton Test System and a real power system have been used to test the results. (C) 2008 Elsevier B.V. All rights reserved.

Transformation of external sensilla to chordotonal sensilla in the cut mutant of Drosophila assessed by single-cell marking in the embryo and larva

The cut gene of Drosophila melanogaster is an identity selector gene that establishes the program of development and differentiation of external sense organs. Mutations in the cut gene cause a transformation of the external sense organs into chordotonal organs, originally assessed by the use of immunostaining methods [Bodmer et al. (1987): Cell, 51:293-307]. Because of evidence that axonal projections of the transformed neurons within the central nervous system are not completely switched in cut mutants, the transformation of the four cells making up a sense organ was reassessed using single-cell staining with fluorescent dye and differential interface contrast (DIC) microscopy of the embryo and larva. The results provide strong evidence that all cells of the sense organs are completely transformed, exhibiting the morphologies and organelles characteristic of chordotonal sense organs. A comparison of the structures of external sense organs and chordotonal organs indicates that a number of the differences could be due to the degree of development of common structures, and that cut or downstream genes modulate effector genes that are normally utilized in both receptor types. The possible derivation of insect chordotonal and external sense organs from a receptor type found in crustaceans is discussed in the light of arthropod phylogenetics and the molecular genetics of sense organ development.

Movement-related potentials in Parkinson's disease: External cues and attentional strategies

Hypokinetic movement can be greatly improved in Parkinson's disease patients by the provision of external cues to guide movement. It has recently been reported, however, that movement performance in parkinsonian patients can be similarly improved in the absence of external cues by using attentional strategies, whereby patients are instructed to consciously attend to particular aspects of the movement which would normally be controlled automatically. To study the neurophysiological basis of such improvements in performance associated with the use of attentional strategies, movement-related cortical potentials were examined in Parkinson's disease and control subjects using a reaction time paradigm. One group of subjects were explicitly instructed to concentrate on internally timed responses to anticipate the presentation of a predictably timed go signal. Other subjects were given no such instruction regarding attentional strategies. Early-stage premovement activity of movement-related potentials was significantly increased in amplitude and reaction times were significantly faster for Parkinson's disease subjects when instructed to direct their attention toward internally generating responses rather than relying on external cues. It is therefore suggested that the use of attentional strategies may allow movement to be mediated by less automatic and more conscious attentional motor control processes which may be less impaired by basal ganglia dysfunction, and thereby improve movement performance in Parkinson's disease.
