Physical activity, aerobic fitness, and brain white matter : Their role for executive functions in adolescence
2020
Highlights • Aerobic fitness level, but not physical activity, is related to white matter properties in the brain. • The relation between physical activity and working memory is moderated by fractional anisotropy (FA) of the corpus callosum. • The FA of the corpus callosum and superior corona radiata moderates the relation between aerobic fitness and working memory.
CASE tool support for co-operative work in information systems design
1998
The need for asynchronous co-operative work in design is shown by many surveys of CASE tool use and research on design. MetaEdit+ is a metaCASE environment that allows multiple simultaneous modellers to work together on designing information systems and also information systems design methods. We describe the automatic locking strategies that enable MetaEdit+ to offer a high level of concurrency whilst guaranteeing consistency, enabling effective co-operative work. In particular we describe a new collection data structure that allows high concurrency of updates even at small sizes, fulfilling the need in CASE for largest growth of design information at the start of a project. Finally, we ev…
Semantic infrastructure system with feedback: Application on traffic
2012
The Semantic Web is a powerful approach used by some intelligent applications to manage complex information in many different fields. Nevertheless, there are not standard tools to design and built the applications, therefore each problem need to be analysed separately in order to meet the requirements. In this paper is presented an overview of a system based on a semantic approach with the goal of managing real-time information. The paper studies the application of this system on ITS (Intelligent Transport Systems) as an example of a typical real-time information system. The system gathers real information from the users and the environment, making intelligent decisions and delivering real-…
Main drivers of consultancy services: A meta-analytic approach
2016
Abstract This meta-analysis incorporates the results from 34 separate studies examining fee models for consultancy services whereby the consulting firm provides both audit and advisory services to its customers. The findings indicate a number of key determinants of consultancy bills: client size, audit fees, auditors being from a “Big Audit Firm,” client's financial difficulties, and prior experience with the legal auditors. Conversely, the meta-results fail to correlate the variable of interest with several constructs commonly used in consultancy models such as the auditee's inherent risk, the client's financial debt, or the audit opinion. The study also explores the influence of three mod…
The Monitoring and Advisory Functions of Corporate Boards
2018
The main objective of this chapter is to investigate the effects of advisory directors’ presence on the board’s overall effectiveness in value creation. To achieve this purpose, we first explore the channels through which this advisory measure influences firm value. Thus, the results suggest that the presence of at least one independent director principally committed to advising duties on the board leads to an increase in corporate innovation and a better acquisition performance. We then examine the effect of this measure on firm value. Our findings highlight that the presence of advisory directors on the board is associated with a significant increase in firm value, especially for highly i…
Default Mode Network Efficiency Is Correlated With Deficits in Inhibition in Adolescents With Inhalant Use Disorder
2020
It is well established that alterations in cognitive function and damage to brain structures are often found in adolescents who have substance use disorder (SUD). However, deficits in executive cognitive functioning in adolescents related to the vulnerability and consumption of such substances are not well known. In this study, we use graph theoretic analysis to compare the network efficiency in the resting state for three networks---default mode network (DMN), salience network (SN) and fronto-parietal network (FPN)---between inhalant-consuming adolescents and a control group (12 to 17 years old). We analysed whether the efficiency of these functional networks was related to working memory,…
Executive summary of EPOS 2020 including integrated care pathways.
2020
The European Position Paper on Rhinosinusitis and Nasal Polyps 2020 is the update of similar evidence based position papers published in 2005 and 2007 and 2012 (1-3). The core objective of the EPOS2020 guideline is to provide revised, up-to-date and clear evidence-based recommendations and integrated care pathways in ARS and CRS. EPOS2020 provides an update on the literature published and studies undertaken in the eight years since the EPOS2012 position paper was published and addresses areas not extensively covered in EPOS2012 such as paediatric CRS and sinus surgery. EPOS2020 also involves new stakeholders, including pharmacists and patients, and addresses new target users who have become…
Dimensión metacognitiva de las construcciones sintácticas suspendidas: Estudio descriptivo con pacientes afásicos españoles
2016
By taking into consideration conversational outputs from aphasic Spanish speakers, a functional characterisation of suspended syntactic constructions will be provided here. Suspensions of syntactic constructions may be initially thought of as attributed to a language processing deficit in people with aphasia, which is, in fact, only partly the case. An examination of conversational data demonstrates, however, that a comprehensive explanation of syntactic suspensions requires a re-assessment of this phenomenon in the realm of meta-cognitive processes associated with language behaviour. Five general types of procedures and contexts for suspended syntactic constructions will be proposed and di…
Metalinguaggio nella Valutazione dell'Afasia
2019
Metalinguaggio nella Valutazione dell'Afasia (Rosell-Clari & Hernández-Sacristán, 2019) es una versión adaptada al italiano y abreviada de Rosell Clari & Hernández Sacristán, 2014). Esta prueba fue desarrollada inicialmente para evaluar las habilidades metalingüísticas naturales en personas con afasia (Hernández-Sacristán, Rosell-Clari, Serra-Alegre y Quiles-Climent, 2012). Las habilidades metalingüísticas naturales se refieren al uso del lenguaje que revela reflexividad (Hockett, 1960); es decir, la distancia perceptiva del hablante con respecto a su propio comportamiento verbal (Werner & Kaplan, 1978). Esta autoconciencia del lenguaje nos permite monitorear nuestros propios comportamiento…
Evaluating the missing links in the relationship between executives' compensation and firm performance
2014
The research on the relationship between executive compensation and firm performance is extensive but has produced inconsistent results and, typically, weak explanatory power. One cause of these results is use of an incomplete theoretical framework that ignores some variables that are related to these two concepts. We explore the missing links between them. The paper contributes to scholarly and practical understanding of this important issue in the literature by extending and combining agency theory, upper echelons theory, and motivation theory perspectives. The paper develops a model that describes and explains the interactive relationship between executive managerial ability, executive c…
