In der gegenwärtigen "Wissensgesellschaft" spielt wissenschaftliches Wissen eine zentrale Rolle, um gesellschaftliche Verhältnisse herzustellen oder zu reproduzieren. Ein kritischer Umgang mit (wissenschaftlichem) Wissen - eine "critical science literacy" - eröffnet Möglichkeiten des Widerstands in der Wissensgesellschaft und kann damit als demokratische Grundfertigkeit begriffen werden. Im vorliegenden Beitrag gehen die Autorinnen den Möglichkeiten einer critical science literacy im Spannungsverhältnis von Anpassung und Widerstand nach. Sie werfen einen Blick auf die historische Entwicklung der Debatte um scientific literacy - ursprünglich nur als naturwissenschaftliche Grundkompetenz gedacht, aber mit einem durchaus kritisch reflexiven und demokratischen Moment - im Kontext demokratisch-kapitalistischer Verhältnisse. Sie verstehen critical science literacy als eine auf allen Ebenen der Wissensgenerierung und -bildung verantwortungsvolle, kollektive und eingreifende Praxis in gesellschaftliche Auseinandersetzungen.

O presente relatório tem como objetivo a explanação e a discussão de forma concisa da atividade docente desenvolvida no ano letivo 2012/2013, na Escola Básica 2,3/S Cunha Rivara de Arraiolos com as turmas do 8.º C e 11.º D nas disciplinas de Ciências Naturais e Saúde respetivamente, sob a orientação da Doutora Marília Cid. Apresentam-se os fundamentos teóricos que sustentaram o delineamento de todas as metodologias e estratégias de ensino no sentido de promover situações de aprendizagem significativa aos alunos das turmas referidas. Este é também um testemunho da participação ativa no projeto de educação para a saúde em colaboração com as entidades promotoras de saúde no Concelho de Arraiolos no sentido de organizar atividades extracurriculares propiciadoras da aprendizagem nesta dimensão, com a dinamização de sessões de esclarecimento de Educação Sexual a várias turmas da escola e a produção de um website informativo e de apoio aos alunos do 3.º Ciclo do Ensino Básico e do Ensino Secundário sobre Educação Sexual. Foi apanágio deste trabalho a análise e reflexão também evidenciadas no trabalho de investigação sobre as atividades desenvolvidas no âmbito da Educação para a Saúde mas também em toda a atividade de lecionação. Esta análise e reflexão, bem como a pesquisa individual e o trabalho colaborativo permitiram o desenvolvimento progressivo das minhas capacidades, da qualidade do trabalho desenvolvido e o melhoramento da formação académica. /ABSTRACT: This report aims at explaining concisely and discussion of teaching developed in the academic year 2012/2013, at Escola Básica 2,3 / S Cunha Rivara in Arraiolos with classes C from 8th grade class and D from 11th , in the disciplines of Natural Sciences and Health respectively under the guidance of PhD Teacher Marilia Cid. Here we present the theoretical foundations that supported the design of all methodologies and teaching strategies to promote meaningful learning situations for students of classes above. This is also a testament to the active participation in the design of health education in collaboration with the health promoters in the County of Arraiolos to organize extracurricular activities conducive learning these dimensions, the organization of information sessions to various Sex Education school classes and the production of an informational website to support the students of the 3rd cycle and Secondary Education on Sexual Education. It was the hallmark of this work, analysis and reflection evidenced in research work on the activities within the Health Education but also of the entire teaching activity. This analysis and reflection as well as individual research and collaborative work allowed the progressive development of my abilities, quality of work and the improvement of academic training.

Taro (Colocasia esculenta L. Schott) is an important crop worldwide but is of particular significance in many Pacific Island countries where it forms part of the staple diet and serves as an export commodity. Escalating pest and disease problems are jeopardizing taro production with serious implications to food security and trade. Biotechnological approaches to addressing pest and disease problems, such as somatic embryogenesis and transgenesis, are potentially viable options. However, despite biotechnological advancements in higher profile agronomic crops, such progress in relation to Colocasia esculenta var. esculenta has been slow. This paper reviews taro biology, highlights the cultural and economic significance of taro in Pacific Island countries and discusses the progress made towards the molecular breeding of this important crop to date.

The world we live in is well labeled for the benefit of humans but to date robots have made little use of this resource. In this paper we describe a system that allows robots to read and interpret visible text and use it to understand the content of the scene. We use a generative probabilistic model that explains spotted text in terms of arbitrary search terms. This allows the robot to understand the underlying function of the scene it is looking at, such as whether it is a bank or a restaurant. We describe the text spotting engine at the heart of our system that is able to detect and parse wild text in images, and the generative model, and present results from images obtained with a robot in a busy city setting.

Many of the teaching elements in Civil and Environmental Engineering and Spatial Science/Surveying are strongly related to multidisciplinary real-world situations. Professionals in each discipline commonly work collaboratively, knowing each other’s professional and technical limitations and requirements. Replication of such real-world situations allows students to gain an insight and acquire knowledge of professional practice for both civil engineering and spatial science disciplines. However, replication of an authentic design project is not always possible in a single unit basis where empirical project situations are often created with controlled sets of constraints, inputs and outputs. A cross-disciplinary design-based project that is designed to promote active student learning, engagement and professional integration would be the preferred option. The central aim of this collaborative project was to create positive and inclusive environments to promote engaging learning opportunities that cater for a range of learning styles with a two-way linkage involving third-year civil engineering and spatial science (surveying) students. This paper describes the cross-disciplinary project developed and delivered in 2010 and 2011. A survey was conducted at completion of the project to assess the degree of improvement in student engagement and their learning experiences. Improvements were assessed in a range of dimensions including student motivation, learning by cross-disciplinary collaboration and learning by authentic design project experiences. In this specific cross-disciplinary linkage project, the study findings showed that teaching approaches utilised have been effective in promoting active student learning and increasing engagement.

The method on concurrent multi-scale model of structural behavior (CMSM-of-SB) for the purpose of structural health monitoring including model updating and validating has been studied. The detailed process of model updating and validating is discussed in terms of reduced scale specimen of the steel box girder in longitudinal stiffening truss of a long span bridge. Firstly, some influence factors affecting the accuracy of the CMSM-of-SB including the boundary restraint regidity, the geometry and material parameters on the toe of the weld and its neighbor are analyzed using sensitivity method. Then, sensitivity-based model updating technology is adopted to update the developed CMSM-of-SB and model verification is carried out through calculating and comparing stresses on different locations under various loading from dynamic characteristic and static response. It can be concluded that the CMSM-of-SB based on the substructure method is valid.

We investigated the potential of an extract of Lycopodium obscurum L.; stigmastane-3-oxo-21-oic acid (SA), to enhance osteogensis of mouse osteoblastic MC3T3-E1 cells. SA at a concentration of 16 µM was found to have no significant effect upon the viability of the cells, thus concentrations of 8 µM and 16 µM of SA were used in all further experiments. Both concentrations of SA had an inhibitory affect upon alkaline phosphatase activity (ALP) after 8 days incubation, however, after 16 days activity was restored to control levels. However Alizarin red S staining showed increased levels of mineralization for both concentrations after 16 days culture. Real time PCR showed inhibition of genes Runx2 and Osterix genes responsible for the up-regulation of ALP. However early time point (8 days) up-regulation of bone matrix mineralization genes OPN and OCN, and late time point (16 days) up-regulation of both Jun-D and Fra-2 mRNA expression was significantly enhanced. These results suggest a potential me-chanism of SA in enhancing bone fracture healing is through the up-regulating bone matrix minera-lization.

In recent years, some models have been proposed for the fault section estimation and state identification of unobserved protective relays (FSE-SIUPR) under the condition of incomplete state information of protective relays. In these models, the temporal alarm information from a faulted power system is not well explored although it is very helpful in compensating the incomplete state information of protective relays, quickly achieving definite fault diagnosis results and evaluating the operating status of protective relays and circuit breakers in complicated fault scenarios. In order to solve this problem, an integrated optimization mathematical model for the FSE-SIUPR, which takes full advantage of the temporal characteristics of alarm messages, is developed in the framework of the well-established temporal constraint network. With this model, the fault evolution procedure can be explained and some states of unobserved protective relays identified. The model is then solved by means of the Tabu search (TS) and finally verified by test results of fault scenarios in a practical power system.

In spite of the activism of professional bodies and researchers, empirical evidence shows that project management still does not deliver the expected benefits and promises. Hence, many have questioned the validity of the hegemonic rationalist paradigm anchored in the Enlightenment and Natural Sciences tradition supporting project management research and practice for the last 60 years and the lack of relevance to practice of the current conceptual base of project management. In order to address these limitations many authors, taking a post-modernist stance in social sciences, build on ‘pre-modern’ philosophies such as the Aristotelian one, specially emphasizing the role of praxis (activity), and phronesis (practical wisdom, prudence). Indeed, ‘Praxis … is the central category of the philosophy which is not merely an interpretation of the world, but is also a guide to its transformation …’ (Vazquez, 1977:. 149). Therefore, praxis offers an important focus for practitioners and researchers in social sciences, one in which theory is integrated with practice at the point of intervention. Simply stated, praxis can serve as a common ground for those interested in basic and applied research by providing knowledge of the reality in which action, informed by theory, takes place. Consequently, I suggest a ‘praxeological’ style of reasoning (praxeology being defined as study or science of human actions and conduct, including praxis, practices and phronesis) and to go beyond the ‘Theory-Practice’ divide. Moreover, I argue that we need to move away from the current dichotomy between the two classes ‘scholars experts-researchers’ and ‘managers/workers-practitioners-participants’. Considering one single class of ‘PraXitioner’, becoming a phronimos, may contribute to create new perspectives and open up new ways of thinking and acting in project situations. Thus, I call for a Perestroika in researching and acting in project management situations. My intent is to suggest a balanced praxeological view of the apparent opposition between social and natural science approaches. I explore, in this chapter, three key questions, covering the ontological, epistemological and praxeological dimensions of project management in action. 1. Are the research approaches being currently used appropriate for generating contributions that matter to both theory and practice with regards to what a ‘project’ is or to what we do when we call a specific situation ‘a project’? 2. On the basis of which intellectual virtues is the knowledge generated and what is the impact for theory and practice? 3. Are the modes of action of the practitioners ‘prudent’ and are they differentiating or reconciling formal and abstract rationality from substantive rationality and situated reasoning with regards to the mode of action they adopt in particular project situations? The investigation of the above questions leads me to debate about ‘Project Management-as-Praxis’, and to suggest ‘A’ (not ‘THE’) ‘praxeological’ style of reasoning and mode of inquiry – acknowledging a non-paradigmatic, subjective and kaleidoscopic perspective – for ‘Knowing-as-Practicing’ in project management. In short, this is about making a ‘Projects Science’ that matters.
