We sought to improve the feasibility of strain rate imaging (SRI) during dobutamine stress echocardiography (DSE) in 56 subjects at low risk of coronary disease. The impact of several SRI changes during acquisition were studied, including: (1) changing from fundamental to harmonic imaging; (2) parallel beam-forming; (3) alteration of spatial resolution and (4) narrow sector acquisition. We assessed SR signal quality, a quantitative measure of signal noise and measurements of SRI. Of 1462 segments evaluated, 6% were uninterpretable at rest and 8% at peak stress. Signal quality was optimised by increasing temporal (p = 0.01) and spatial resolution (p<0.0001 vs. baseline imaging) at rest and peak. Increasing spatial resolution also minimised signal noise (p<0.0001). Inter-observer variability of time to peak SR and peak SR were less with high temporal and spatial resolution. SRI quality can be improved with harmonic imaging and higher temporal resolution but optimisation of spatial resolution is critical. (C) 2004 World Federation for Ultrasound in Medicine Biology.

Este estudo tem por objetivo avaliar o nível de sociabilização no comportamento da criança/adolescente com deficiência intelectual em terapia assistida por animais, TAA, e por objetivos específicos levantar o perfil sócio-demográfico-clínico dessa população, observar o comportamento da criança em atendimento mediado pela TAA e verificar a opinião dos pais/responsáveis e profissionais sobre essa terapia. A TAA é uma técnica na qual o animal é parte integrante do processo terapêutico. Enquadra-se em uma abordagem multidisciplinar, que requer a intervenção de especialistas, na qual o cão ocupa uma posição mediadora entre o paciente e os objetivos terapêuticos. A pesquisa abrange 46 sujeitos, sendo 20 pacientes, 20 pais e/ou responsáveis e seis terapeutas, e desenvolve-se em uma clínica de Reabilitação Clínica de ONG em cidade de grande porte. Foram observadas 12 intervenções em TAA, aplicada a escala com foco em sociabilização baseada em Achenbach (ASEBA)e realizada entrevista junto aos pais/responsáveis e entrevistados os terapeutas em TAA. Os resultados dos instrumentos utilizados convergem no sentido de apontara validade da TAA como facilitadora da sociabilização das crianças/adolescentes com deficiência intelectual, com aumento da motivação e engajamento às intervenções, assim como, com repercussões positivas em sua autonomia, em seu humor e em sua organização cognitiva temporal e narrativa linguística. Os terapeutas ressaltam o componente lúdico presente nas intervenções, o qual facilita atingir seus objetivos terapêuticos. Já para os pais dos atendidos por essa abordagem, de forma unanime referem que filhos demonstram motivação e maior autonomia frente aos atendimentos. O estudo sugere novas investigações que possam dar suporte à divulgação dessa modalidade de terapia.

The image and style of political leaders are important elements of leadership, and of politics generally. They are related to both political culture and institutions, and are framed in ritual and ceremony. In democratic policies, where there is choice rather than coercion, the mediation of leadership/people relations creates imagined relationships between imagined leaders and their equally imagined interlocutors, the people or the electorate (who also, of course, actually exist). These relationships form part of the political process. By identifying, and adapting, classical Aristotelian distinctions in rhetorical studies, we can better understand this element or moment of the process, in particular the creation of an imagined intimacy in contemporary politics between leaders and followers. Political science should draw upon other disciplines and subdisciplines such as political psychology, cultural studies, rhetorical analysis, and social anthropology in order to understand how mediated relationships are inscribed into political institutions and exchange.

Ironically, the “learning of percent” is one of the most problematic aspects of school mathematics. In our view, these difficulties are not associated with the arithmetic aspects of the “percent problems”, but mostly with two methodological issues: firstly, providing students with a simple and accurate understanding of the rationale behind the use of percent, and secondly - overcoming the psychological complexities of the fluent and comprehensive understanding by the students of the sometimes specific wordings of “percent problems”. Before we talk about percent, it is necessary to acquaint students with a much more fundamental and important (regrettably, not covered by the school syllabus) classical concepts of quantitative and qualitative comparison of values, to give students the opportunity to learn the relevant standard terminology and become accustomed to conventional turns of speech. Further, it makes sense to briefly touch on the issue (important in its own right) of different representations of numbers. Percent is just one of the technical, but common forms of data representation: p% = p × % = p × 0.01 = p × 1/100 = p/100 = p × 10-2 "Percent problems” are involved in just two cases: I. The ratio of a variation m to the standard M II. The relative deviation of a variation m from the standard M The hardest and most essential in each specific "percent problem” is not the routine arithmetic actions involved, but the ability to figure out, to clearly understand which of the variables involved in the problem instructions is the standard and which is the variation. And in the first place, this is what teachers need to patiently and persistently teach their students. As a matter of fact, most primary school pupils are not yet quite ready for the lexical specificity of “percent problems”. ....Math teachers should closely, hand in hand with their students, carry out a linguistic analysis of the wording of each problem ... Schoolchildren must firmly understand that a comparison of objects is only meaningful when we speak about properties which can be objectively expressed in terms of actual numerical characteristics. In our opinion, an adequate acquisition of the teaching unit on percent cannot be achieved in primary school due to objective psychological specificities related to this age and because of the level of general training of students. Yet, if we want to make this topic truly accessible and practically useful, it should be taught in high school. A final question to the reader (quickly, please): What is greater: % of e or e% of Pi

Experimental methods of policy evaluation are well-established in social policy and development eco-nomics but are rare in industrial and innovation policy. In this paper, we consider the arguments forapplying experimental methods to industrial policy measures, and propose an experimental policy eval-uation approach (which we call RCT+). This approach combines the randomised assignment of firmsto treatment and control groups with a longitudinal data collection strategy incorporating quantitativeand qualitative data (so-called mixed methods). The RCT+ approach is designed to provide a causativerather than purely summative evaluation, i.e. to assess both ‘whether’ and ‘how’ programme outcomesare achieved. In this paper, we assess the RCT+ approach through an evaluation of Creative Credits – aUK business-to-business innovation voucher initiative intended to promote new innovation partnershipsbetween SMEs and creative service providers. The results suggest the potential value of the RCT+ approachto industrial policy evaluation, and the benefits of mixed methods and longitudinal data collection.

Most authors assume that the natural behaviour of the decision-maker is being inconsistent. This paper investigates the main sources of inconsistency and analyses methods for reducing or eliminating inconsistency. Decision support systems can contain interactive modules for that purpose. In a system with consistency control, there are three stages. First, consistency should be checked: a consistency measure is needed. Secondly, approval or rejection has to be decided: a threshold value of inconsistency measure is needed. Finally, if inconsistency is ‘high’, corrections have to be made: an inconsistency reducing method is needed. This paper reviews the difficulties in all stages. An entirely different approach is to elaborate a decision support system in order to force the decision-maker to give consistent values in each step of answering pair-wise comparison questions. An interactive questioning procedure resulting in consistent (sub) matrices has been demonstrated.
