¿Why fail the software development projects?
La investigación permitió elaborar una relación actualizada de las causas principales por las cuales los proyectos de desarrollo de software fracasan, tomando como punto de partida la revisión de lo investigado por otros autores y contrastándolo con los testimonios de profesionales activos que lideran o hacen parte de equipos de trabajo que se dedican a la ejecución de proyectos de desarrollo de softwareThe investigation develop an updated major cause regarding why development projects software fail, taking as its starting point the review of the investigations of other authors and contrasting it with the testimonies of active professionals who lead or are part of teams work devoted to the implementation of software development projects
Los efectos del MIPRESS en el Sistema de Seguridad Social en salud en Colombia
Artículo de ReflexiónEl sistema de seguridad social en salud en Colombia ha surtido diversas transformaciones con el transcurso de los años, en principio el Estado únicamente brindaba una atención básica a los ciudadanos. Con el paso de tiempo esto fue cambiando a medida que se reconocieron los derechos del ciudadano frente al Estado. La expedición de la Constitución Política de 1991 que introduce el concepto del Estado Social de Derecho, indica que es fin esencial del mismo la prestación de servicios públicos a la mayoría de la población, por ello, el derecho a la salud se desarrolla en la Ley 100 de 1993 que crea el sistema de seguridad social integral en el país. Frente a la importancia del derecho a la salud este artículo pretende analizar los cambios que se han dado a la Ley 100 de 1993, específicamente lo contemplado en la Resolución N. 000532 de 2017 que crea la herramienta denominada “Mi prescripción” o MIPRES que corresponde a un mecanismo automatizado en el que los profesionales de salud competentes y autorizados, reportan los servicios o tecnologías que no son cubiertos por la Unidad de Pago por Capitación (UPC), para determinar si esto ha permitido que los usuarios accedan de forma eficaz a los servicios médicos prescritos por el médico tratante.Introducción

Periodic oscillations in the restricted Hip-Hop 2N+1 body problem
We prove the existence of periodic solutions of the restricted -body
problem when the -primaries move on a periodic Hip-Hop solution and the
massless body moves on the line that contains the center of mass and is
perpendicular to the base of the antiprism formed by the -primaries.Comment: 12 pages, 5 figure
Quantum Enhancements via Tribracket Brackets
We enhance the tribracket counting invariant with \textit{tribracket
brackets}, skein invariants of tribracket-colored oriented knots and links
analogously to biquandle brackets. This infinite family of invariants includes
the classical quantum invariants and tribracket cocycle invariants as special
cases, as well as new invariants. We provide explicit examples as well as
questions for future work.Comment: 12 pages. Version 2 includes typo corrections and suggestion from

Issues and perspectives on the use of exotic species in the sustainable management of Canadian forests
Plantations offer a high potential to respond to the increasing pressure on forests to deliver social, economic, and environmental services. Exotic tree species have a long history of use in plantation forestry, mostly because of their improved productivity compared with that of native species. Because of their impacts on land management and the environment, questions arise regarding the compatibility of exotic tree plantations with sustainable forest management (SFM), the overarching paradigm driving forest legislations in Canada. Our objectives were thus to i) briefly review the historical and current use of exotic tree species in Canada, ii) identify the social, economic and environmental issues related to the use of exotic tree species in Canadian forestry, based on sustainable forest management criteria, and iii) identify perspectives related to the use of exotic tree species in the sustainable management of Canadian forests. Results show that six out of ten Canadian provinces do not have specific legislations to control the use of exotic tree species for reforestation within their borders. The use of exotic tree species is mainly controlled through third-party certification agencies. Exotic tree species represent a small proportion of the planted seedlings in Canada and Norway spruce is the most common one. The use of exotic tree species is compatible with sustainable forest management criteria used in Canada, but forest managers must take into account several issues related to their use and maintain a social license to be entitled to plant them. Issues are highly dependent upon scale. The zoning of management intensity could provide environmental, economic and social benefits, but costs/benefits analyses should be carried out. The concept of naturalness could also be useful to integrate plantations of exotic species in jurisdiction where SFM strategies are based on ecosystem management principles. Monitoring of hybridization and invasiveness of exotic species must be included in landscape analyses to forestall loss of resilience leading to compromised structural and functional ecosystem states. The use of exotics species is recognized as a tool to sequester carbon and facilitate adaptation of forests to global changes, but it is necessary to carefully identified contexts where assisted migration is justified and disentangle planned novel ecosystems coherent with global changes generated by assisted migration from those emerging from invasive species forming undesired states
On the density of matroids omitting a complete-graphic minor
We show that, if is a simple rank- matroid with no -point line
minor and no minor isomorphic to the cycle matroid of a -vertex complete
graph, then the ratio is bounded above by a singly exponential
function of and . We also bound this ratio in the special case where
is a frame matroid, obtaining an answer that is within a factor of two of
best-possible.Comment: 25 page
