A opinião de crianças em idade pré-escolar sobre os seus pares com deficiência

Este estudo teve como objetivo avaliar o conhecimento, as perceções e a intenção comportamental - as atitudes - das crianças em idade pré-escolar com desenvolvimento típico relativamente aos seus pares com incapacidade ou deficiência. As atitudes das crianças foram avaliadas a partir da observação de fotografias de crianças de três grupos distintos: (1) com incapacidade intelectual, (2) com incapacidade motora e (3) sem incapacidades. Participaram nesta investigação 34 crianças a frequentar o ensino pré-escolar, com mais de 4 anos de idade e com desenvolvimento típico. Os participantes foram selecionados de 4 salas com crianças com Necessidades Adicionais de Suporte (NAS) e 4 sem crianças com NAS. A recolha dos dados foi efetuada através de quatro instrumentos: "Understanding Disability Scale", "Perceived Attributes Scale", "Perceived Capacibilities Scale", "Behavioral Intentions Scale". Os resultados obtidos indicaram a existência de muitas dúvidas sobre o que é a deficiência física e incapacidade intelectual. Relativamente à perceção de atributos e capacidades, verificou-se que existem opiniões mais positivas em relação aos pares com desenvolvimento típico comparativamente aos pares com incapacidades. Ao nível da intenção comportamental, os resultados mostraram que não existem diferenças entre os três grupos, isto é, o facto de os pares terem um desenvolvimento típico ou terem incapacidade intelectual ou deficiência física, não determina a predisposição das crianças para interagirem perante os mesmos. Contrariamente à nossa expectativa, o ambiente educativo (inclusivo vs. nãoinclusivo, isto é, ter ou não na mesma turma colegas com incapacidades ou deficiência) não tem um impacto significativo nas atitudes das crianças

Supermarkets in Portugal: corporate social responsibility image, attitude towards the brand and purchase intention

Recently, companies developed strategies which may influence their Corporate Social Responsibility (CSR) image. This paper discusses the image of four different supermarkets with stores in Portugal. The research compares CSR image and brand attitude of the four supermarkets. Empirical evidence shows that different supermarkets belonging to the same company have different CSR image and brand attitude. The research also confirms that there is positive correlation between CSR image and attitude towards the brand. Further, the results offer empirical evidence that CSR image and brand attitude influence purchase intention of supermarket brands. Finally, brand purchase intention is highly influenced by attitude towards the brand than CSR image.

Volunteering for a lifetime? Volunteers’ intention to stay in Portuguese hospitals

Purpose – The current study aims to study Hospital volunteers’ intention to stay in an organization through understanding motivation, management factors and satisfaction. Design/methodology/approach – A total of 304 Hospital volunteers, mainly women, completed a questionnaire measuring motivations, management factors, satisfaction and intention to stay. In this study structural equation modelling was used. Findings – Results demonstrate that there is a positive relationship between (a) motivation and satisfaction, (b) management factors and satisfaction, (c) satisfaction and intention to stay and (d) motivation and management factors. These results present important outcomes that should be reflected in the way organizations operate. Research limitations/implications – This research was restricted to a health care context and to the opinion of only one stakeholder (volunteers). We assume volunteer intent to stay is a main predictor of retention. However, there are other variables not considered here that might influence intent to stay. Practical implications – This research indicates aspects which are most valued by volunteers and allows NPOs to design and establish appropriate and assertive management policies. Originality/value – The value of this paper is that it looks at understanding what factors influence volunteers’ intention to stay.

POSIX trace based behavioural reflection

Traditional Real-Time Operating Systems (RTOS) are not designed to accommodate application specific requirements. They address a general case and the application must co-exist with any limitations imposed by such design. For modern real-time applications this limits the quality of services offered to the end-user. Research in this field has shown that it is possible to develop dynamic systems where adaptation is the key for success. However, adaptation requires full knowledge of the system state. To overcome this we propose a framework to gather data, and interact with the operating system, extending the traditional POSIX trace model with a partial reflective model. Such combination still preserves the trace mechanism semantics while creating a powerful platform to develop new dynamic systems, with little impact in the system and avoiding complex changes in the kernel source code.

Study of behavioural and neural bases of visuo-spatial working memory with an fMRI paradigm based on an n-back task

The goal of this study was to propose a new functional magnetic resonance imaging (fMRI) paradigm using a language-free adaptation of a 2-back working memory task to avoid cultural and educational bias. We additionally provide an index of the validity of the proposed paradigm and test whether the experimental task discriminates the behavioural performances of healthy participants from those of individuals with working memory deficits. Ten healthy participants and nine patients presenting working memory (WM) deficits due to acquired brain injury (ABI) performed the developed task. To inspect whether the paradigm activates brain areas typically involved in visual working memory (VWM), brain activation of the healthy participants was assessed with fMRIs. To examine the task's capacity to discriminate behavioural data, performances of the healthy participants in the task were compared with those of ABI patients. Data were analysed with GLM-based random effects procedures and t-tests. We found an increase of the BOLD signal in the specialized areas of VWM. Concerning behavioural performances, healthy participants showed the predicted pattern of more hits, less omissions and a tendency for fewer false alarms, more self-corrected responses, and faster reaction times, when compared with subjects presenting WM impairments. The results suggest that this task activates brain areas involved in VWM and discriminates behavioural performances of clinical and non-clinical groups. It can thus be used as a research methodology for behavioural and neuroimaging studies of VWM in block-design paradigms.
