Potential of technology and a familiar context to enhance students' concept of rate of change

Students' concept image of rate of change may be incomplete or erroneous. This paper reports a pilot study, with secondary school students, which explores the potential of technology (JavaMathWorlds), depicting a familiar context of motion, to develop students' existing schema of informal understandings of rate of change to more formal mathematical representations. Students developed numerous 'models of' rate of change in a motion context which then transferred to serve as a 'model for' rate of change in other contexts.

Retrieval-induced forgetting of performed and observed bizarre and familiar actions

To investigate whether people show retrieval-induced forgetting (RIF) for bizarre and familiar actions that they performed or observed, three experiments were conducted. In Experiment 1, participants performed bizarre and familiar actions with different objects during learning (e.g., pencil: balance the pencil across the cup, sharpen the pencil). They repeatedly performed a set of the bizarre or familiar actions during retrieval practice. After a distracter task, participants’ cued recall was tested. Participants showed RIF for both bizarre and familiar actions. In Experiment 2, half of the participants performed the bizarre and familiar actions themselves; the other half observed the experimenter performing the actions. Replicating the results of Experiment 1, participants who performed the actions showed RIF for bizarre and familiar actions. In contrast, participants who observed the actions did not show RIF for either action type. Experiment 3 examined whether this lack of RIF for observed actions occurred due to a lack of active recall during retrieval practice; it did. Overall, the three experiments demonstrated RIF for both bizarre and familiar performed and observed actions. A distinctiveness account of the results is provided.

The strange and the familiar : seeing beyond when we know

My novel is a collection of interrelated stories. Each story is framed by the idiosyncrasies and prejudices of a different first-person voice. There are gaps in narrative time and there is disparity between the narrators’ voices. The result is a ‘discontinuous narrative’; this term describes the early work of Frank Moorhouse: ‘an innovative narrative method using interconnected stories’ (Griffith University 2011).
As I draft and re-draft the stories, I am forced to assess the interaction between the voices. I am aware of the disjuncture, and I ask myself: Why not tell the story through the eyes of one narrator? Why not choose a third-person perspective, an omniscient narrator who might collect all of the voices together, in a coherent way?
As I second-guess my approach, I realise that the splintering of voices feels like the right way to tell the story and, in this way, I approach the question of methodology. I am aware that a sense of disjuncture arises out of the medley of voices, but I also realise that the disjuncture is carefully constructed; it is not accidental. This is an intuitive judgement.
If I edit my novel ethically, I ask what the discontinuity achieves, rather than how it fails in the context of logic. This means that I recognise that the narrative begins from a place that does not worry about logic, and I realise that second-guessing the surface content of the narrative, from a rational perspective, may be counterproductive.
The conscious mind, fettered as it is with inhibitions, may fail to see that the logical track is not necessarily the most productive route. The conscious mind may not recognise that going off-track is the way forward and, perhaps, the only way that the story can become something other than what I, in my rational mind, believe that it should be.
Ethical editing means that I am attentive to my intuitive response to the narrative; it means that I tolerate incongruous elements of the narrative, even if they do not fit the criteria of logic.
Ethical editing is a meeting of minds (both mine); the fully conscious mind meets the work of the subconscious mind with surprise and approval, at best, skepticism and derision, at worst. The work of the subconscious mind is elusive but it need not be subjugated to logical, rational considerations, for this means that I delimit the work of the subconscious; it means I assess the discontinuity on the basis of an external operating system; it means that I impose certain criteria upon the surface narrative, criteria that has nothing to do with understanding why the discontinuity exists in the first instance.
Alternatively, when I pay heed to a primal moment of narrative composition, a moment that is not necessarily consciously determined or logical, I apprise the surface of the narrative as a metaphorical map, I attempt to engage with the possibilities for meaning that the map encompasses; this constitutes a quest for the unstable how of meaning attribution.

Ocupação, bem-estar e satisfação de vida: a experiência de um modelo alternativo de estágio em terapia ocupacional na Austrália

An alternative training model within occupational therapy developed at Deakin University, in Australia, named Occupation, Wellness and Life-Satisfaction (OWLS) is presented. OWLS provides students with opportunities to practice in nontraditional settings, thus enabling strategic learning in non-clinical settings, including working with professionals who are not occupational therapists and with different work cultures and practices, in response to gaps identified within the community. It promotes opportunities for developing skills such as health promotion, health education and assessment and interventions in schools, thus improving the health and wellbeing of the community. The program has contributed towards development of new projects, with positive results achieved by students, thereby representing an important educational strategy for professional occupational therapy training and expanding the field of activities.

Vivência/experiência na realização da atenção humanizada Ao recém nascido de baixo peso – método mãe canguru na Unidade de terapia intensiva neonatal

A Atenção Humanizada ao Recém Nascido de baixo Peso- Método Mãe Canguru tem por finalidade o contato pele a pele precoce entre a mãe e o filho, fortalecendo o vínculo entre eles. Visto a importância deste método, decidiu-se realizar um estudo de natureza qualitativa com mães que realizaram dentro de uma Unidade de Terapia Intensiva o método mãe canguru com seu recém nascido de baixo peso, com o objetivo de descrever a experiência, a vivência e as dificuldades de se realizar este método em uma situação de hospitalização. Os dados foram analisados de acordo com a Teoria Fundamentada nos Dados, e emergiram sete categorias: Vivenciando o Sofrimento; Sendo apoiada e orientada a estreitar o contato com o filho; Dedicando-se ao filho; Sentindo-se mãe; Acompanhando o progresso do bebê; Percebendo a reciprocidade afetuosa do filho; Estreitando outros laços afetivos. Estas categorias revelam alguns aspectos de como se dá esta experiência da mãe com o recém nascido e revelam que o método mãe canguru contribui não só na formação de vínculo entre a díade mãe-filho, como também com entes próximo a ela e, além disso, na melhora do quadro clínico do RN de baixo peso.

Terapia das construções de concreto : metodologia de avaliação de sistemas epoxi destinadas a injeção de fissuras passivas das estruturas de concreto

A perda do desempenho de uma edificação está associada ao aparecimento de patologias. A escolha de uma adequada terapia para os problemas encantrados, depende de um diagnóstico preciso do caso. A fissuração do concreto é alvo deste trabalho, por ser ela uma das manifestacoes patológicas mais incidentes nas edificacões, tanto a nível nacional como mundial. Nesse trabaho os diversos tipos de fissuras verificadas no concreto são agrupadas em ativas e passivas. Apresenta-se,H ainda, os materiais e técnicas de recuperacão para corrigir as fissuras dos dois grupos. Entre as soluções mais adotadas para recuperar as problemas patológicos, as que utilizam sistemas de base epóxi possuem destaque. O trabalho faz uma discussão sobre os fatores que influenciam o desempenho de sistemas epóxi destinados à injeção de fiissuras passivas do concreto e apresenta ensaios que podem ser realizados para garantir o sucesso da técnica. Ao final, apresenta um exemplo de avaliação de sistemas epóxi, encontradas no mercado nacional, destinados à injecão de fissuras e uma análise dos resultados obtidos.
