Embedded Real-Time Surveillance Using Multimodal Mean Background Modeling
2008
Automated video surveillance applications require accurate separation of foreground and background image content. Cost-sensitive embedded platforms place real-time performance and efficiency demands on techniques to accomplish this task. In this chapter, we evaluate pixel-level foreground extraction techniques for a low-cost integrated surveillance system. We introduce a new adaptive background modeling technique, multimodal mean (MM), which balances accuracy, performance, and efficiency to meet embedded system requirements. Our evaluation compares several pixel-level foreground extraction techniques in terms of their computation and storage requirements, and functional accuracy for three r…
Cyber Security Strategy Implementation Architecture in a Value System
2018
In this chapter, we introduce an approach toward enhancing the quality of strategy implementation. As a framework, we use cybersecurity strategy implementation planning and execution. Justification for this work is the observed need to be able to perform strategy readjustment processes quickly and in an agile way, when needed. This requires processes and practices that are simple enough and executable with small resources in a relatively short timeframe. The problem statement can be formulated as follows: “We need to determine an utterly simplified, noncomplicated model to help us to tackle the complex problem of implementing a cybersecurity strategy of adequate efficiency in a changing ope…
The effects of the provision of consulting services on audit reporting quality
2012
The growing complexity of the global business environment is leading innovative firms to demand further external counselling to better handle rapid change and increasing uncertainty. Likewise, the implementation of new information systems is usually carried out with the help of external advisors. This paper examines whether the provision of consulting services undermines audit reporting quality by testing for an association between advisory services and audit reporting. A cross-sectional logistic regression is estimated to test the relationship between consulting fees and the audit outcome. The evidence suggests that there is no statistically significant association between non-audit fees a…
Disciplinary Sanctions and Audit Quality: Empirical Evidence from an External Oversight System
2010
This paper provides empirical evidence on the impact of disciplinary sanctions on audit quality, based on the external oversight system set up in Spain in the early nineties. Specifically, we examine the effects of the sanctions imposed by the Institute of Accounting and Auditing (ICAC), a government regulatory agency independent from the auditing industry. To proxy for audit quality, two client-specific earnings quality indicators are considered; i.e. the likelihood of loss reporting and abnormal accruals. According to our results, the Spanish external oversight system does not penalise isolated but structural audit malpractice, since sanctioned auditors exhibit lower average audit quality…

The role of executive function in social competence and behavioral problems in the last year of preschool
2018
Diverse studies have found a relationship between executive function, behavioral problems and social competence. However, until this moment, few studies have investigated the role of the distinct components of executive function in social competence, or in the most frequently encountered behavioral problems in childhood education. For this reason, the principal objective of this article is to evaluate the relation of the exec-utive functions with behavioral problems and social competence in infancy. The study included 260 students in their last year of preschool. The results of path analysis showed that all components of executive functions predict, at least, a behavioral problem. However, …
La jurisprudencia del Tribunal Constitucional chileno sobre tratados internacionales: el específico caso de las cláusulas autoejecutables y no autoej…
2016
El presente trabajo se pronuncia sobre el tratamiento específico que ha dado la magistratura constitucional chilena a la cuestión de las cláusulas autoejecutables y no autoejecutables de los tratados internacionales, y sobre si dicho tratamiento es adecuado conforme al sistema constitucional de incorporación y vigencia del derecho convencional internacional en el ordenamiento jurídico nacional. This paper deals with the specific treatment that has given the Constitutional Court of Chile on the question of self-executing and non-self-executing provisions of international treaties, and whether the treatment is appropriate under the constitutional system of incorporation and validity of intern…
Cognitive Deficits and Associated ERP N400 Abnormalities in FXTAS With Parkinsonism
2018
Objective: To examine cognitive deficits and associated brain activity in fragile X-associated tremor/ataxia syndrome (FXTAS) patients with parkinsonism (FXTp+), in relation to FXTAS patients without parkinsonism (FXTp-), and normal elderly controls (NC). Methods: Retrospective reviews were performed in 65 FXTAS patients who participated in the event-related brain potential (ERP) study and also had either a videotaped neurological examination or a neurological examination for extrapyramidal signs. Parkinsonism was defined as having bradykinesia with at least one of the following: rest tremor, postural instability, hypermyotonia, or rigidity. Eleven FXTp+ patients were identified and compare…
Voluntary Imitation in Alzheimer’s Disease Patients
2016
International audience; Although Alzheimer's disease (AD) primarily manifests as cognitive deficits, the implicit sensorimotor processes that underlie social interactions, such as automatic imitation, seem to be preserved in mild and moderate stages of the disease, as is the ability to communicate with other persons. Nevertheless, when AD patients face more challenging tasks, which do not rely on automatic processes but on explicit voluntary mechanisms and require the patient to pay attention to external events, the cognitive deficits resulting from the disease might negatively affect patients' behavior. The aim of the present study was to investigate whether voluntary motor imitation, i.e.…
Association between osteocalcin and cognitive performance in healthy older adults.
2016
INTRODUCTION: cognitive deterioration and reductions of bone health coincide with increasing age. We examine the relationship between bone composition and plasma markers of bone remodelling with measures of cognitive performance in healthy adults.METHODS: this cross-sectional study included 225 old (52% women, mean age: 74.4 ± 3.3 years) and 134 young (52% women, mean age: 23.4 ± 2.7 years) adult participants from the MyoAge project. Whole body bone mineral density was measured by dual-energy X-ray absorptiometry. Blood analyses included a panel of bone-related peptides (dickkopf-1, osteoprotegerin, osteocalcin (OC), osteopontin, sclerostin, parathyroid hormone and fibroblast growth factor …
