Geometrically frustrated Fe2P-like systems: beyond the Fe-trimer approximation.

Fe(2)P-like structures can be strongly frustrated magnets due to their Kagome/triangular intercalated-layer structure. A complete magnetic solution of the complex spin architecture, and hence the full potential of the magnetic phenomena in Fe(2)P-like material prototypes, is yet to be found. A previous magnetic model for a representative FeCrAs-like system used a mean-field effective-spin to describe the 3g-Wyckoff located Fe-triangles. Such an approach demonstrated the outstanding magnetocaloric properties of the material but left the question of whether the intra-trimer interaction could lead to new physical phenomena and therefore more potentially useful properties. In this work Monte Carlo simulations are employed in order to understand both the influence of the additional degrees of freedom introduced by the Fe-trimers and the changes caused by all the possible exchange couplings between them. Complex scenarios arise, in which FM coupling in the trimers gives rise to both in-plane and out-of-plane inter-layer AFM states; whereas AFM exchange in the trimers gives rise to three distinct states, i.e. AFM-canted layers, a non-collinear superposition of ferromagnetic Kagome/triangular orderings, and tilted inter-planar AFM order. These last three configurations generate a double bifurcated magnetic phase diagram while the first one mimics the behavior seen in a model that treats the trimer as an effective-spin under an applied magnetic field.

Building bridges to promote globalization in nursing: the development of a hermanamiento.

The establishment of a hermanamiento (sister school) partnership between Duquesne University School of Nursing in Pittsburgh, Pennsylvania, United States, and the School of Nursing at the Polytechnic University in Managua, Nicaragua, is described. Also discussed is the Regis Group Model, under which the hermanamiento was developed, and suggestions of how to develop a similar international nursing partnership. One component of a comprehensive model for international partnership and collaboration is presented in detail. The activities and goals that were established and implemented by both schools of nursing provide a philosophic and transcultural backdrop on which the program was based.

Teaching cardiac rhythm strip interpretation within a cross-cultural context: using Nicaraguan nurses as a model.

Critical care nurses have been interpreting rhythm strips in the United States for years, and recently this concept has become a new responsibility for critical care nurses in Nicaragua. The focus of this article is on the unique challenges encountered by a nurse educator when teaching critical care concepts to non-English-speaking critical care nurses. Using Nicaraguan nurses as a model, the author shares experiences of teaching advanced concepts to non-English-speaking nurses. The specific concept taught was rhythm strip interpretation and the potential value in nursing care practice.
