Abstract: the professional specific competences constitute a range of competences associated fundamentally with the action and apprehension of the reality. these competences are very influence by the professional formation and experience in the profession. for that reason, in the case of professional specific competences is very important and necessary an organized formation professional characterized by the accumulation of learning and abilities in specific tasks linked with the profession. in the present paper, two experiences in projects of courses developed by engineering students in the learning process are showed; moreover some results in the formation and development of professional specific competences associated with mentioned projects are illustrated. these experiences allow affirming that the professional specific competences can be developed during the professional formation with the introduction in the learning process of certain activities practical-professionals. in this sense, the practical activity in the academic with reproduction of frequent problems in relation with the profession is a very appropriate environment to develop the formation of professional specific competences demand in the current context of action for the graduate of careers of mechanical engineering.

Underage & Overweight: America s Childhood Obesity Crisis What Every Family Needs to Know
Chodaesessie Wellesley-Cole Morgan
Preventing Chronic Disease , 2004,
Abstract: Underage & Overweight: America s Childhood Obesity Crisis What Every Family Needs to Know was written primarily for parents, teachers, school administrators, doctors, nurses, other health care professionals, and policymakers. The author, Frances M. Berg, has written a thoroughly researched, evidence-based textbook that emphasizes the importance of a multifaceted approach to alleviating the childhood obesity crisis in the United States. Other books have been written about encouraging healthy lifestyles in children and adolescents, but those authors tend to concentrate on narrowly focused strategies (i.e. diet, exercise, diet and/or exercise) to encourage weight loss among children and adolescents. Anyone who is concerned about, or who has an interest in, the issues and complexities of childhood obesity should obtain a copy of this book and keep it as a reference text.
Sexual violation and trauma in historical perspective
Bourke, Joanna
Arbor : Ciencia, Pensamiento y Cultura , 2010, DOI: 10.3989/arbor.2010.743n1205
Abstract: Trauma is not a universal way of speaking about the effects of “bad events” but is socially constructed. In the case of rape, psychological trauma is a relatively recent way of conceptualising the aftermath of violence. This article examines the development within psychiatric, legal, and forensic textbooks of the notion of “trauma” in reference to rape victims, and investigates the reasons for its relatively recent application. El trauma no constituye una forma universal de expresión de los efectos de un “suceso desagradable” sino que es construido socialmente. En el caso de la violación, el trauma psicológico es una forma relativamente reciente de conceptualizar las consecuencias de la agresión. En este artículo se examina el desarrollo de la noción de trauma en manuales psiquiátricos, legales y forenses, a propósito de las víctimas de violación, y se investigan las razones para su relativamente reciente puesta en práctica.
Low Cost Projection Environment for Immersive Gaming
Paul Bourke
Journal of Multimedia , 2008, DOI: 10.4304/jmm.3.1.41-46
Abstract: As computer performance and graphics hardware continue to improve, the gamer is increasingly being presented with richer and more realistic visual environments. Viewing these virtual environments is generally still based upon display technology that does not exploit two very important characteristics of our visual system, namely stereoscopic vision that is responsible for the enhanced depth perception we see in the real world and a wide field of view that allows us to sense activity in our far peripheral vision. In what follows it will be argued that for immersive gaming a wide field of view is both functionally more useful and places less stress on the visual system than stereoscopic viewing. In order to support gaming with a wide vertical and horizontal field of view a low cost projection system will be introduced and the implications for game developers discussed.
Two dimensional monadicity
John Bourke
Mathematics , 2012,
Abstract: The behaviour of limits of weak morphisms in 2-dimensional universal algebra is not 2-categorical in that, to fully express the behaviour that occurs, one needs to be able to quantify over strict morphisms amongst the weaker kinds. F-categories were introduced to express this interplay between strict and weak morphisms. We express doctrinal adjunction as an F-categorical lifting property and use this to give monadicity theorems, expressed using the language of F-categories, that cover each weaker kind of morphism.
Skew structures in 2-category theory and homotopy theory
John Bourke
Mathematics , 2015,
Abstract: We study Quillen model categories equipped with a monoidal skew closed structure that descends to a genuine monoidal closed structure on the homotopy category. Our examples are 2-categorical and include permutative categories and bicategories. Using the skew framework, we adapt Eilenberg and Kelly's theorem relating monoidal and closed structure to the homotopical setting. This is applied to the construction of monoidal bicategories arising from the pseudo-commutative 2-monads of Hyland and Power.
