Visual efficiency detection index : a new composite measure of visual search

Visual search is an important component of our interaction with our surroundings, allowing us to successfully identify external cues that impact our spatial navigation. Previous research has established fixation duration, fixation count, saccade velocity, and saccade amplitude as important indices of visual search. We examined the Visual Efficiency Detection Index (VEDI) comprising multiple aspects of visual search performance into a single measure of global visual performance. Forty participants, 10 adults ages 22-48, and children ages 6, 8, and 10, completed tests of working memory and visual search in response to stimuli relevant to pedestrian decision making. Results indicated VEDI statistically relates to established indices of visual search in relation to their interpretability for human performance. The VEDI was also sensitive to developmental differences in visual search performance, suggesting insight to its utility in the developmental psychological literature.

Collaborative business networks evaluation of technological tools for decision support making

Nowadays, companies are living great difficulties on managing their business due to constant and unpredictable economic market fluctuations. Recent changes in market trends (such as the constant demand for new products and services, mass customization and the drastic reduction of delivery time) lead companies to adopt strategies of creating partnerships with other companies as a way to respond effectively to such difficult economical times. Collaborative Networks’ concept born by the consequence of companies could no longer consider their internal business processes’ management as sufficient and tend to seek for a collaborative approach with other partners for their critical processes. Information technologies (ICT) assumed a major role acting as “enablers” of these kinds of networks, enhancing information sharing and business process integration. Several new trends concerning ICT architectures have been created to support collaborative networks requirements, but still doesn’t exist a common platform to reduce the needed integration effort on virtual organizations. This study aims to investigate the current technological solutions available in the market which enhances the management of companies’ business processes (specially, Collaborative Planning). Finally, the research work ends with the presentation of a conceptual model to answer to the constraints evaluated.

A gestão por processos como fator diferencial na usabilidade de recursos tecnológicos dentro dos empreendimentos virtuais

O presente estudo propõe-se a discutir a questão da utilização da gestão por processos para o melhor tratamento da usabilidade de tecnologia dentro das organizações. Normalmente as organizações utilizam o que chamamos de gestão funcional e esse tipo de administração apresenta uma série de situações divergentes da gestão por processos, as quais serão mostradas e analisadas. Será também retratado o papel do gestor no desempenho desta função e as vantagens do trabalho em equipe. A seguir serão abordadas considerações sobre tecnologia, cujo objetivo é o entendimento necessário às condições que serão contempladas no cruzamento de ideias com a gestão por processos. O trabalho trará ainda considerações teóricas sobre organizações virtuais e empreendedorismo para que se possa melhor conhecer o cenário onde o alinhamento final das ideias desse estudo será abordado, envolvendo gestão por processos, tecnologia e empreendimentos virtuais. O trabalho mostrará uma pesquisa baseada na observação pessoal e na aplicação de entrevista junto a duas empresas de sucesso que atuam no mercado de empreendimentos virtuais no Estado do Pará. O objetivo desta prática é identificar a utilização e aplicabilidade dos princípios de uma adequada gestão tecnológica discutida e sugerida por esse estudo, comprovando sua eficiência nos negócios organizacionais virtuais.

Efficiency and social inclusion: implications for the museum profession

In the late 1980s Stephen Weil (1990) raised the question of the extent to which museum work could be considered a profession, the extent to which it had been professionalized, and in what ways this professionalization was facilitated or impeded by the changing circumstances of museum work, its organizational and governance context and its already multiplying roles vis-à-vis public culture and society at large. Although Weil‘s thoughts were situated in the American museum context of the mid-1980s, many of his thoughts apply to contexts beyond the US, and some of the questions he raised about the potential for professionalising museum work still resonate with the current situation of museum work. This paper tries to pose and approach a host of questions that, whilst in the main echoing Stephen Weil‘s mid-1980s reflections, are reconfigured in light of some sweeping changes in the nature of museum work, its mode of governance and its governing norms and values.

Response to Anwar Tlili‘s paper -Efficiency and social inclusion: implications for the museum profession

I have been asked to respond to Anwar Tlili‘s paper, and I propose to do this in four steps. I will follow Anwar‘s line of arguments closely. I will be dealing in turn withStep no. 1: Profession and ProfessionalizationStep no. 2: Social InclusionStep no. 3: ManagerialismStep no. 4: Museum Education and Training

A Study on the Efficiency of Synbiotics for Prevention and Control of Diarrhoea in 21 Dogs Submitted to Radiotherapy

A synbiotic is a formulation containing both probiotics and prebiotics. This study aims to evaluate the effect of supplementation with a synbiotic containing Enterococcus faecium strain E1707 (NCIMB 10415) in preventing or controlling diarrhoea and other gastrointestinal signs in boarded canine radiotherapy patients. A double-blind, randomized, placebocontrolled clinical trial was carried out in 21 adult dogs undergoing radiotherapy and boarded for a duration period of 2 to 3 weeks to treat their cancers. Dogs were randomly divided between two groups: A and B, the synbiotic and placebo group, respectively. The content of the sachets was added to the food once daily. Faecal score was assessed daily, and dogs were also monitored for the development of diarrhoea and other gastrointestinal signs such as weight loss, reduced appetite and vomiting. The results from descriptive statistics seem to favour group B, however these findings were not validated with inferential statistics due to insufficient statistical sample power. Because of this, it is not possible to make conclusions about the benefits of synbiotic as supportive treatment for dogs undergoing radiotherapy. All results should be considered to be preliminary, until they are elucidated by further animal inclusion.
