Engaging Rural Students in a Community Project

eaching art that is relevant to the students and the area one finds themselves working in can sometimes prove to be a challenge. Students and their interests in subject matter can vary depending upon their surroundings. I will share ways teachers can cater instruction towards rural students. Sometimes students in rural areas are in need of a better understanding of art and the importance it holds within the world today. Art is a cultural experience. It is an eye opener to social situations and has functions in fashion, dance and even food. I will conclude with sharing a unit plan, Rural Mural, that incorporates the ideas discussed. In this unit, students collaborate to develop and install a mural that reflects values of their community

Scaling Behaviour and Complexity of the Portevin-Le Chatelier Effect

The plastic deformation of dilute alloys is often accompanied by plastic instabilities due to dynamic strain aging and dislocation interaction. The repeated breakaway of dislocations from and their recapture by solute atoms leads to stress serrations and localized strain in the strain controlled tensile tests, known as the Portevin-Le Chatelier (PLC) effect. In this present work, we analyse the stress time series data of the observed PLC effect in the constant strain rate tensile tests on Al-2.5%Mg alloy for a wide range of strain rates at room temperature. The scaling behaviour of the PLC effect was studied using two complementary scaling analysis methods: the finite variance scaling method and the diffusion entropy analysis. From these analyses we could establish that in the entire span of strain rates, PLC effect showed Levy walk property. Moreover, the multiscale entropy analysis is carried out on the stress time series data observed during the PLC effect to quantify the complexity of the distinct spatiotemporal dynamical regimes. It is shown that for the static type C band, the entropy is very low for all the scales compared to the hopping type B and the propagating type A bands. The results are interpreted considering the time and length scales relevant to the effect.Comment: 35 pages, 6 figure

Ab initio parametrised model of strain-dependent solubility of H in alpha-iron

The calculated effects of interstitial hydrogen on the elastic properties of alpha-iron from our earlier work are used to describe the H interactions with homogeneous strain fields using ab initio methods. In particular we calculate the H solublility in Fe subject to hydrostatic, uniaxial, and shear strain. For comparison, these interactions are parametrised successfully using a simple model with parameters entirely derived from ab initio methods. The results are used to predict the solubility of H in spatially-varying elastic strain fields, representative of realistic dislocations outside their core. We find a strong directional dependence of the H-dislocation interaction, leading to strong attraction of H by the axial strain components of edge dislocations and by screw dislocations oriented along the critical slip direction. We further find a H concentration enhancement around dislocation cores, consistent with experimental observations.Comment: part 2/2 from splitting of 1009.3784 (first part was 1102.0187), minor changes from previous version

Auditoría universitaria y calidad

Consultable des del TDXTítol obtingut de la portada digitalitzadaLa Universidad española tiene en estos momentos ante sí uno de los retos más apasionantes que jamás esta Institución se haya planteado. En primer lugar, la adaptación a los grandes cambios socioeconómicos ocurridos en las últimas décadas que interaccionan desarrollo económico y calidad universitaria. En segundo lugar, como consecuencia de ello, a la búsqueda de la excelencia académica, profesional y científica, que se convierte en un tema clave para la competitividad y la calidad de un país. En tercer lugar, al cambio significativo que ha supuesto la implantación de una armonización universitaria europea a través de la integración y desarrollo en el Espacio Europeo de Educación Superior. Por último, resaltar que el cambio europeo ha quedado sobrepasado por un reto mayor como es la globalización y que ha puesto a las Universidades ya no sólo ante una calidad y competencia europea sino mundial. La calidad y la competitividad de un país no depende solo de la calidad y productividad de sus empresas sino que vendrá determinado en gran parte por la calidad, productividad y competitividad de las Universidades y de sus miembros, tanto en su aspecto investigador como docente. Igualmente el desarrollo económico y del conocimiento de un país tiene mucho que ver con la calidad de la enseñanza de sus universidades. Éstas, al tomar decisiones dentro del ámbito de sus competencias, deberán considerar seriamente su posición competitiva. La Declaración de Bolonia marca las directrices de lo que debe ser la Universidad Europea, de ella se desprende la necesidad de hacer competitiva y atractiva la enseñanza universitaria europea a escala mundial, enfocada a contactar con las necesidades sociales y a hacer más comparables los distintos sistemas educativos. Los Sistemas de Garantía de Calidad son los instrumentos de reforma social y progreso más efectivos que podemos ofrecer en el ámbito universitario, así como una herramienta fundamental para la competitividad y rendición de cuentas. De esta forma se pretende romper con el estereotipo dominante de confundir estos instrumentos con técnicas inherentes y provenientes de la empresa privada en sus manifestaciones más liberales y mercantilistas. En dicho espacio debemos tener en cuenta que el eje mas vertebrado de la armonización van a ser los Sistemas de Garantía de Calidad Universitaria. No podemos olvidar que el cambio europeo ha quedado sobrepasado por un reto mayor, la globalización y que ha situado a las universidades ante una calidad y competencia mundial. No debemos desaprovechar el espacio de educación superior natural, que es Latinoamérica. España tendrá mucho más peso en el Espacio Europeo de Educación Superior si sabe construir rápidamente el Espacio Iberoamericano de Educación Superior. No somos conscientes de que nuestra calidad en Europa depende de que aceleremos el Espacio Iberoamericano dirigido por nosotros mismos con un sistema de evaluación y unos estándares establecidos en ese ámbito Iberoamericano de más de quinientos millones de habitantes de habla española y portuguesa. Esta visión estratégica de acelerar el Espacio Iberoamericano de Educación Superior no es excluyente sino que nos va a reforzar en el Espacio Europeo de Educación Superior y además nos va a servir, como ha sucedido con la experiencia empresarial, para situarnos en la competencia universitaria mundial. Auditoria y evaluación, como a menudo equivocadamente se piensa no es un puro tecnicismo, sino que es un instrumento indispensable para introducir nuevos valores en la sociedad, en el Estado, en la universidad, en la empresa a través de nuevos estándares e indicadores, como son por ejemplo los de calidad ambiental, los de diversidad lingüística y racial en la Universidad, etc. Por tanto la auditoria y evaluación es un sistema muy efectivo de introducir nuevos derechos y valores.The Spanish University has in these moments one of the challenges more exciting that this Institution has never appeared. First, the adjustment to the big socioeconomic changes happened in the last decades that interconnect economic development and university quality. Secondly, as consequence of it, to the search of the academic, professional and scientific excellence, this turns into a key topic for the competitiveness and the quality of a country. Thirdly, to the significant change that has supposed the implantation of a European university harmonization across the integration and development in the European Space of High Education. Finally, to highlight that the European change has remained exceeded by a major challenge as is the globalization and that it has put to the Universities already not only before a quality and European but world competition. The quality and the competitiveness of a country does not depend only on the quality and productivity of its companies but it will come determined largely by the quality, productivity and competitiveness of the Universities and of its members, so much in its investigative as educational aspect. Equally the economic development and of the knowledge of a country there has much that to see with the quality of the education of its universities. These, on having taken decisions inside the area of its competitions, will have to consider seriously its competitive position. The Declaration of Bologna marks the directives what must be the European University, with it there parts the need to make competitive and attractive the university European education on a worldwide scale, focused to contacting with the social needs and to making the different educational systems more comparable. The Systems of guarantee of Quality are the instruments of social reform and progress more workforce that we can offer in the university area, as well as a fundamental tool for the competitiveness and account surrender. Of this form one tries to break with the dominant stereotype of confusing these instruments with technologies inherent and from the private company in its more liberal manifestations and mercantilists. In the above mentioned space we must bear in mind that the axis more vertebrate of the harmonization they are going to be the Systems of Guarantee of University Quality. We cannot forget that the European change has remained exceeded by a major challenge, the globalization and that it has placed to the universities before a quality and world competition. We must not fail to take advantage of the space of top natural education, which is Latin America. Spain will have much more weight in the European Space of High Education if it can construct rapidly the Latin-American Space of High Education. We are not conscious that our quality in Europe depends of that we accelerate the Latin-American Space directed by us themselves with a system of evaluation and a few standards established in this Latin-American area of more than five hundred million inhabitants of Spanish and Portuguese speech. This strategic vision of accelerating the Latin-American Space of High Education is not exclusive but it is going to reinforce us in the European Space of High Education and in addition it is going to serve us, since it has happened with the managerial experience, to place in the university world competition. Audit and evaluation, since often wrongly it is thought is not a pure technicality, but it is an indispensable instrument to introduce new values in the society, in the State, in the university, in the company across new standards and indicators, since they are for example those of environmental quality, those of linguistic and racial diversity in the University, etc. Therefore the audit and evaluation is a very effective system of introducing new rights and values

Food Habits of Wolves in Kluane National Park

The food habits of wolves (Canis lupus) were studied at two different den-sites in Kluane National Park in the southwest of the Yukon Territory, in 1972 and 1973, as part of an assessment of predator-prey dynamics in that newly-designated reserve. No published data exist on the diets of wolves in northern British Columbia or the Yukon Territory; the closest available information concerns the wolf populations of Alaska
