El aprendizaje por competencias en la titulación de enfermería
El presente trabajo propone un enfoque del proceso de enseñanza/aprendizaje de la titulación de Enfermería desde el punto de vista de las competencias, dentro del proceso en el que la Universidad Española está inmersa para adaptarse al Espacio Europeo de Educación Superior (EEES). Este proceso implica un cambio en la mentalidad de todos los universitarios, tanto profesores como alumnos. Para ello el trabajo detalla las competencias que propone el proyecto TUNING, tanto las transversales como las longitudinales, específicas de la titulación de Enfermería. Finalmente, se plantea la conveniencia de establecer para cada una de esas competencias una metodología, que nos serviría para su impartición, y unos resultados de aprendizaje, que nos servirían para la evaluación del alumno al comprobar si se han adquirido las competencias
Galactic cold dark matter as a Bose-Einstein condensate of WISPs
We propose here the dark matter content of galaxies as a cold bosonic fluid
composed of Weakly Interacting Slim Particles (WISPs), represented by spin-0
axion-like particles and spin-1 hidden bosons, thermalized in the Bose-Einstein
condensation state and bounded by their self-gravitational potential. We
analyze two zero-momentum configurations: the polar phases in which spin
alignment of two neighbouring particles is anti-parallel and the ferromagnetic
phases in which every particle spin is aligned in the same direction. Using the
mean field approximation we derive the Gross-Pitaevskii equations for both
cases, and, supposing the dark matter to be a polytropic fluid, we describe the
particles density profile as Thomas-Fermi distributions characterized by the
halo radii and in terms of the scattering lengths and mass of each particle. By
comparing this model with data obtained from 42 spiral galaxies and 19 Low
Surface Brightness (LSB) galaxies, we constrain the dark matter particle mass
to the range and we find the lower bound for the
scattering length to be of the order .Comment: 13 pages; 6 figures; references added; v.3: typo corrected in the

Gastrointestinal Strongyles in Wild Ruminants
Parasitologists have long studied helminth infections in wildlife species and have documented the existence of many organisms from a diversity of mammalian hosts. With this accumulation of information has come improved understanding of the significance of these organisms and the diseases they produce in their mammalian hosts. Some of the most notable examples include the metastrongyloid lungworms, Trichinella spiralis, and Elaeophora schneideri, which are covered separately in this volume. It is, however, for the group of parasites referred to as gastrointestinal nematodes that we have accumulated the most data. Only recently has progress been made in determining the significance of these strongylate nematodes with respect to their potential impact on the morbidity and mortality of the ruminants that they infect.
The accumulation of information on diseases of wild animals into a single combined volume has been slow, but progress has coincided with the proliferation of data for host and parasite interactions. Numerous references including Alaskan Wildlife Diseases (Dieterich 1981), Manual of Common Wildlife Diseases in Colorado (Adrian 1981), Field Manual of Wildlife Diseases in the Southeastern United States (Davidson and Nettles 1988), Zoo and Wildlife Medicine (Fowler 1993), and the previous editions of Parasitic Diseases of Wild Mammals (Davis and Anderson 1971) have all made significant contributions to our knowledge. Beyond North America, Dunn (1969) and Govorka et al. (1988) provided excellent compilations on the helminths in wild ruminants. In the 1971 printing of Parasitic Diseases of Mammals, however, there was no general coverage of gastrointestinal nematodes, and only T. spiralis was addressed. Herein, we present the first synoptic review of the strongylate nematodes that occur in the gastrointestinal system of wild ruminants from North America
Bounds on the mass and abundance of dark compact objects and black holes in dwarf spheroidal galaxy halos
We establish new dynamical constraints on the mass and abundance of compact
objects in the halo of dwarf spheroidal galaxies. In order to preserve
kinematically cold the second peak of the Ursa Minor dwarf spheroidal (UMi
dSph) against gravitational scattering, we place upper limits on the density of
compact objects as a function of their assumed mass. The mass of the dark
matter constituents cannot be larger than 1000 solar masses at a halo density
in UMi's core of 0.35 solar masses/pc^3. This constraint rules out a scenario
in which dark halo cores are formed by two-body relaxation processes. Our
bounds on the fraction of dark matter in compact objects with masses >3000
solar masses improve those based on dynamical arguments in the Galactic halo.
In particular, objects with masses solar masses can comprise no
more than a halo mass fraction . Better determinations of the
velocity dispersion of old overdense regions in dSphs may result in more
stringent constraints on the mass of halo objects. For illustration, if the
preliminary value of 0.5 km/s for the secondary peak of UMi is confirmed,
compact objects with masses above solar masses could be excluded
from comprising all its dark matter halo.Comment: 6 pages, 2 figures, accepted for publication in ApJ Letter
Intervención conductual en autocontrol y prevención de las conductas de riesgo en el alumnado de enfermería
INTRODUCCIÓN
En todo programa formativo de habilidades prácticas que conllevan algún tipo de
riesgo, necesariamente se plantea el dilema acerca de qué priorizar, la prudencia frente
a los riesgos de un posible accidente por la inexperiencia, o la adquisición de la
experiencia, asumiendo los riesgos que este proceso conlleva. La formación práctica
del alumnado de enfermería representa un caso típico del dilema que estamos
planteando, pero, dado el tipo de consecuencias que dichos accidentes producirían
(con un peligro evidente para su salud), ha de realizarse estableciendo unas pautas que
garanticen la formación sin poner en riesgo ni al propio estudiante ni al paciente que se
atiende.
A lo largo de este trabajo hemos tratado de responder a esta cuestión a través del
desarrollo de un programa de formación y de intervención en el alumnado de
Diplomatura y Grado de Enfermería de la Universidad de Córdoba durante los años
académicos 2008 al 2013. Para ello hemos tenido en cuenta los modelos explicativos
de las conductas de riesgo aplicables a la Prevención de Riesgos Laborales, que consta
de una fase de divulgación de información sobre el riesgo de sufrir accidentes
biológicos y su control, pero que añade un enfoque interventivo, que no se conforma
con poner en marcha las medidas de prevención en el ambiente físico, ni con ofrecer la
formación e información adecuadas, sino que va más allá en el intento de garantizar
efectos reales sobre la seguridad de estudiantes y usuarios
OBJETIVOS
El Objetivo Principal de esta investigación fue fomentar los hábitos y conductas
preventivas ante el riesgo biológico en el alumnado de Ciencias de la Salud de la
Universidad de Córdoba que realizan sus prácticas en centros sanitarios y disminuir el
riesgo de accidentes, sobre todo biológicos, en dicho alumnado durante el desarrollo
de sus prácticas clínicas. Para ello pretendimos influir en el comportamiento arriesgado,
elaborando un Plan de Prevención que no sólo se ajustara a los aspectos informativoscognitivos,
sino que se complementara con otros que pudieran mejorar el efecto de la
formación...INTRODUCTION
In all practical skills training program involving some kind of risk, necessarily the
dilemma about what to prioritize arises, caution against the risks of a possible accident
by inexperience, or the acquisition of experience, assuming the risks that this process
involves. The practical training of the students in nursing represents a typical case
about the dilemma we are proposing, nevertheless, given the type of consequences
that such accidents would cause (with an obvious health hazard), it has to be done by
establishing guidelines to ensure training without putting at risk neither to the student
himself nor to the patient to whom they attend.
Throughout this work we have tried to answer this question through the development
of a training and intervention program in students of Diploma and Degree of Nursing at
the University of Cordoba, during the academic years 2008 to 2013, taking into account
the explanatory models of risk behaviors applicable to the Prevention of Occupational
Risks, it is consisting of a phase of spreading of information about the risk of suffering
biological accidents and his control; moreover, it adds an interventional approach,
which does not content with implementing prevention measures in the physical
environment nor to provide appropriate training and information, but goes further in
an attempt to ensure a real impact on the safety of students and users.
OBJECTIVES
The main objective of this research was to promote preventive habits and behaviors to
the biological risk in students of Health Sciences of the University of Cordoba who
perform their practices in health centers and reduce the risk of accidents, especially
biological, during the development of their clinical practice. To do this we sought to
influence risky behavior, developing a Prevention Plan that not only is conformed to
the informative-cognitive, but is complemented by others that could improve the effect
of training.
The specific objectives were:
1. Describe the risk against the biological accident of students of the Faculty of
Nursing at the University of Cordoba, in order to develop a specific Prevention..
