Engineers' professional learning: a practice-theory perspective

With the increasing challenges facing professional engineers working in more complex, global and interdisciplinary contexts, different approaches to understanding how engineers practice and learn are necessary. This paper draws on recent research in the social sciences from the field of workplace learning, to suggest that a practice-theory perspective on engineers' professional learning is fruitful. It shifts the focus from the attributes of the individual learner (knowledge, skills and attitudes) to the attributes of the practice (interactions, materiality, opportunities and challenges). Learning is thus more than the technical acquisition and transfer of knowledge, but a complex bundle of activities, that is, social, material, embodied and emerging. The paper is illustrated with examples from a research study of the learning of experienced engineers in the construction industry to demonstrate common practices – site walks and design review meetings – in which learning takes place.

What young people say about physical activity: the children's sport and physical activity study

The Children’s Sport Participation and Physical Activity (CSPPA) study is a unique multi-centre/ discipline study undertaken by three Irish institutions, Dublin City University, University of Limerick and University College Cork. The study sought to assess participation in physical activity, physical education and sport (PAPES) among 10-18 year olds in Ireland. This paper shares what Irish children and young people convey, using their own voices, about their sport and physical activity (PA) experiences and how such experiences may result in their feeling included or excluded in PAPES. Eighteen focus groups (FG) with 124 boys and girls elicited descriptive data from students and were conducted with homogeneous groups of 6-8 boys and girls aged 12-18 years (selected for convenience) identified as male/female, primary/post-primary and generally active/ inactive. Five themes (‘being with friends’, ‘variety in activity content’, ‘experiencing fun’, ‘time constraints’ and ‘opportunity to be outside’) ran across the three PAPES opportunities for young people. Overall data revealed that these young people have a positive attitude towards PA which does not diminish as they age despite activity levels decreasing. Other choices of activity participation (e.g. debate, music), or more focused activities took the place of previous choices as young people came to realise what they most enjoyed. If we are to encourage and provide opportunities for young people to choose active lifestyles, it is important that we address what these young people report affects their involvement in PA across a number of contexts. Two such developments within Irish school and community contexts are discussed: Active School Flag initiative and Senior Cycle Physical Education framework.

Development of a dynamic surface roughness monitoring system based on artificial neural networks (ANN) in milling operation

Dynamic surface roughness prediction during metal cutting operations plays an important role to enhance the productivity in manufacturing industries. Various machining parameters such as unwanted noises affect the surface roughness, whatever their effects have not been adequately quantified. In this study, a general dynamic surface roughness monitoring system in milling operations was developed. Based on the experimentally acquired data, the milling process of Al 7075 and St 52 parts was simulated. Cutting parameters (i.e., cutting speed, feed rate, and depth of cut), material type, coolant fluid, X and Z components of milling machine vibrations, and white noise were used as inputs. The original objective in the development of a dynamic monitoring system is to simulate wide ranges of machining conditions such as rough and finishing of several materials with and without cutting fluid. To achieve high accuracy of the resultant data, the full factorial design of experiment was used. To verify the accuracy of the proposed model, testing and recall/verification procedures have been carried out and results showed that the accuracy of 99.8 and 99.7 % were obtained for testing and recall processes.

Practising social inclusion

Practising Social Inclusion presents what we know about what works, and why, in promoting social inclusion and practising in a socially inclusive way. Contributing to the growing debates on social inclusion, this book moves beyond discussion of who it is that is socially excluded and the processes of exclusion. It draws on research and reflective practice to answer the vital question of how to actually work towards inclusion and includes five sections looking at different arenas for practice: policy; programme design; service delivery; community life; and research. Relevant to all those working to promote, or researching, human health and wellbeing, this book is especially suitable for practitioners, students and scholars in health promotion, social work, social policy, public health, disability studies, occupational therapy and nursing.
