Internal audit involvement in enterprise risk management

Purpose – The purpose of this paper is to examine the impact of internal auditors’ involvement in enterprise risk management (ERM) on perceptions of their willingness to report a breakdown in risk procedures and whether a strong relationship with the audit committee affects such willingness to report. The study also investigates the use of ERM and the role of internal audit in ERM in Australian private and public sector entities.
Design/methodology/approach – The study uses an experimental design, manipulating the internal auditor’s involvement in ERM and the strength of the relationship between internal audit and the audit committee. Participants are 117 certified internal auditors. The study also gathers descriptive data on the use of ERM.
Findings – The study indicates that a high involvement in ERM impacts the perceptions of internal
auditors’ willingness to report a breakdown in risk procedures to the audit committee. However, a strong relationship with the audit committee does not appear to affect their perceived willingness to report. The study also finds that the majority of organisations have recently adopted ERM. Internal auditors are involved in ERM assurance activities but some also engage in activities that could compromise objectivity.
Research limitations/implications – There are internal and external validity threats associated with the experimental design.
Practical implications – The findings reinforce the need for organisations to adhere to the recommendations of the Institute of Internal Auditors and to ensure that internal auditors do not play an inappropriate role in ERM.
Originality/value – The paper contributes to our understanding of the impact of involvement in ERM on internal audit objectivity and of the current role of internal audit in ERM in Australia.

Reliability and validity of a reactive agility test for Australian football

Purpose: The aim of this study was to test the reliability and construct validity of a reactive agility test (RAT), designed for Australian Football (AF).

Methods: Study I tested the reliability of the RAT, with 20 elite junior AF players (17.44 ± 0.55 y) completing the test on two occasions separated by 1 wk. Study II tested its construct validity by comparing the performance of 60 participants (16.60 ± 0.50 y) spread over three aged-matched population groups: 20 athletes participating in a State Under-18 AF league who had represented their state at national competitions (elite), 20 athletes participating in the same league who had not represented their state (subelite), and 20 healthy males who did not play AF (controls).

Results: Test-retest reliability reported a strong correlation (0.91), with no significant difference (P = .22) between the mean results (1.74 ± 0.07 s and 1.76 ± 0.07 s) obtained (split 2+3). Nonparametric tests (Kruskal-Wallis and Mann-Whitney) revealed both AF groups performed significantly faster on all measures than the control group (ranging from P = .001 to .005), with significant differences also reported between the two AF groups (ranging from P = .001 to .046). Stepwise discriminant analyses found total time discriminated between the groups, correctly classifying 75% of the participants.

Conclusions: The RAT used within this study demonstrates evidence of reliability and construct validity. It further suggests the ability of a reactive component within agility test designs to discriminate among athletes of different competition levels, highlighting its importance within training activities.

Evaluation of biogenic amines in the faeces of children with and without autism by LC-MS/MS

Previous researchers have postulated that gastrointestinal bacteria may contribute to the development and maintenance of Autism Spectrum Disorders (ASD). There is evidence based on quantitative evaluation of the gastrointestinal bacterial population in ASD that this is unlikely and an alternate mechanism will be examined where the bacteria may contribute to the development of ASD via their metabolic products and the role of biogenic amines (BAs) will be investigated. In humans, BAs influence a number of physiological processes via their actions as neurotransmitters, local hormones and gastric acid secretion. Various amines have been implicated in several medical conditions such as schizophrenia and colon cancer. To date, the relationship between BAs and autism has not been explored. This study has been designed to identify differences (and/or similarities) in the level of Bas in faecal samples of autistic children (without gastrointestinal dysfunction: n = 14; with gastrointestinal dysfunction; n = 21) and their neurotypical siblings (n = 35) by LC-MS/MS. Regardless of the diagnosis, severity of ASD and gastrointestinal dysfunction there were no significant differences found between the groups. The findings suggest that BAs in the gastrointestinal tract do not play a role in the pathophysiology of gastrointestinal dysfunction associated with ASD.

Video Game Training and Reaction Time Skills Among Older Adults

The aim of the current study was to examine whether reaction time (RT) among older adults could be improved through video game training. Twenty-nine participants between the ages of 50 and 84 either played (N = 14) or did not play (N = 15) a video game, Pac-Man: Adventures in Time. All participants completed a pre- and postassessment of RT. Results from this study showed that there were no significant differences between the control and experimental groups on RT performance across time. These findings indicate that the amount of training provided may have been inadequate to improve RT skills. It is therefore important to investigate the amount of training required to allow older adults to respond faster to environmental stimuli and transfer skills to activities of daily living.

Wielding the big stick – Lessons for enforcing anti-discrimination law from the Fair Work Ombudsman

Anti-discrimination law is enforced by a person who has experienced discrimination by lodging a complaint at a statutory equal opportunity agency. The agency is responsible for receiving and resolving discrimination complaints and educating the community; it does not play a role in enforcing the law. The agency relies on ‘carrots’ to encourage voluntary compliance, but it does not wield any ‘sticks’. This is not the case in other areas of law, such as industrial relations, where the Fair Work Ombudsman is charged with enforcing the law — including the prohibition of discrimination in the workplace — and possesses the necessary powers to do so. British academics Hepple, Coussey and Choudhury developed an enforcement pyramid for equal opportunity. This article shows that the model used by the Fair Work Ombudsman reflects what Hepple, Coussey and Choudhury propose, while anti-discrimination law enforcement would be represented as a flat, rectangular structure. The article considers the Fair Work Ombudsman’s discrimination enforcement work to date and identifies some lessons that anti-discrimination law enforcement can learn from its experience.

Prevalência da expressão imunoistoquímica da proteína p21 em adenocarcinoma do esôfago

INTRODUÇÃO: No mundo ocidental, a prevalência de adenocarcinoma da junção esofagogástrica vem crescendo nas últimas décadas. Atualmente, é aceito que o adenocarcinoma do esôfago se desenvolve de uma lesão pré-maligna: esôfago de Barrett. Este carcinoma é de difícil diagnóstico nos seus estágios iniciais, o que resulta em uma mortalidade significativa. O estudo da biologia molecular tem demonstrado que grande parte dos tumores malignos tem origem na interação entre o componente hereditário e influências externas, que em indivíduos predispostos podem ocasionar alterações genéticas que influenciem o controle da diferenciação e crescimento celular. O p21 (WAF1/CIP1) tem um papel fundamental na regulação do ciclo celular, e sua expressão imunoistoquímica tem sido estudada em diversos tumores, mostrando influência no prognóstico de várias neoplasias. OBJETIVO: Verificar a prevalência da expressão da proteína p21 em pacientes com adenocarcinoma de esôfago diagnosticados nos últimos cinco anos no Grupo de Cirurgia de Esôfago e Estômago do Hospital de Clínicas de Porto Alegre (GCEE/HCPA). METODOLOGIA: A população em estudo foi constituída de 42 pacientes com adenocarcinoma de esôfago diagnosticados no GCEE/HCPA entre janeiro de 1998 e dezembro de 2002. A expressão da proteína p21 foi realizada por meio de imunoistoquímica, com anticorpo primário, p21, clone SX118, código M7202 da DAKO, e avaliada de acordo com o Sistema de Escore de Imunorreatividade (Immunoreactive scoring system – IRS). RESULTADOS: Foram estudados 42 pacientes. 83,3% eram do sexo masculino, com idade superior a 40 anos. Destes, 56,2% foram submetidos a procedimentos cirúrgicos com intenção curativa: Gastrectomia total e Esofagogastrectomia transiatal. Os demais foram submetidos à cirurgia paliativa ou não sofreram tratamento cirúrgico. Apenas cinco pacientes receberam tratamento adjuvante com quimioterapia e radioterapia, isoladas ou combinadas. Quanto ao estadiamento, 78,6% dos pacientes apresentavam doença avançada, estádios III e IV. Apenas 9 apresentaram positividade para o p21, quando considerado o Sistema de Escore de Imunorreatividade (em que p21+ é ³ 3). CONCLUSÃO: A proteína p21 esteve expressa em 9 dos 42 pacientes (21,4%) com adenocarcinoma de esôfago diagnosticados nos últimos cinco anos no Grupo de Cirurgia de Esôfago e Estômago do Hospital de Clínicas de Porto Alegre. Nessa casuística, o acúmulo de p21 não se mostrou essencial no processo de carcinogênese do adenocarcinoma esofágico.

A (des)necessidade do conceito de capital social no direito societário brasileiro: uma análise à luz do direito norte-americano e europeu

O trabalho analisa o tema do capital social no direito societário brasileiro. Seu objetivo é demonstrar, do ponto de vista jurídico, os malefícios e benefícios que o instituto promove. Apesar de ser tido como um conceito clássico e essencial para as sociedades com limitação de responsabilidade no Brasil, esse instituto vem sendo cada vez mais criticado no sentido de que não desempenha suas funções clássicas (organização, produção, e proteção de credores) de maneira efetiva nos dias atuais. Nesse contexto, direito societário moderno vem passando por uma evolução no sentido de questionar a efetividade de seus institutos. A análise aqui proposta do capital social segue esse raciocínio. Para auxiliar na interpretação do instituto no Brasil, serão utilizadas serão estudadas as lições e legislações dos ordenamentos europeu e norte-americano, onde o tema já foi amplamente debatido. O tratamento dado pelo Revised Model Business Corporation Act, legislação modelo norte americana, e da Segunda Diretiva do Capital da União Europeia aos instituto serão comparados com o tratamento da Lei das S.A. para o capital social. Por fim, são identificadas algumas particularidades do instituto do capital social em relação aos ordenamentos estrangeiros, que demonstram que uma eventual supressão do conceito de capital social no Brasil possuiria características próprias que não estão presentes na Europa e nos Estados Unidos. Nesse contexto, serão identificados os custos legislativos que uma eventual mudança do regime de capital social teria no sistema legislativo brasileiro.

O menino é o pai do homem: raízes crianceiras do conhecimento

This dissertation is a work on playing and its relation with the knowledge production process. It is the result of a set of personal experiences with the cultural universe of children which have instigated a look into the way they explore the world and questions about the very nature of the games they play. Could we consider those games hide, or rather reveal important strategies used in the knowledge production process and in making science. In light of several studies concerning the complexity of science, this questioning has also led to the development of a toy (a box), which consists of a range of pieces (photos, video, audio, stones, seeds, rags, envelopes, etc.). My intention is to show in a practical manner a strategy of thinking similar to the sensitive logic bricolage present in the playing, in order to instigate the reflection on the possibility of its inclusion in the production of the knowledge and science making processes

Control of breathing in anuran amphibians

The primary role of the respiratory system is to ensure adequate tissue oxygenation, eliminate carbon dioxide and help to regulate acid-base status. To maintain this homeostasis, amphibians possess an array of receptors located at peripheral and central chemoreceptive sites that sense respiration-related variables in both internal and external environments. As in mammals, input from these receptors is integrated at central rhythmogenic and pattern-forming elements in the medulla in a manner that meets the demands determined by the environment within the constraints of the behavior and breathing pattern of the animal. Also as in mammals, while outputs from areas in the midbrain may modulate respiration directly, they do not play a significant role in the production of the normal respiratory rhythm. However, despite these similarities, the breathing patterns of the two classes are different: mammals maintain homeostasis of arterial blood gases through rhythmic and continuous breathing, whereas amphibians display an intermittent pattern of aerial respiration. While the latter is also often rhythmic, it allows a degree of fluctuation in key respiratory variables that has led some to suggest that control is not as tight in these animals. In this review we will focus specifically on recent advances in studies of the control of ventilation in anuran amphibians. This is the group of amphibians that has attracted the most recent attention from respiratory physiologists. (c) 2006 Elsevier B.V. All rights reserved.
