Querido lector, estamos seguros de que frases como “El emprendimiento como motor del crecimiento y desarrollo económico y social de los países” le resultan de sobra conocidas, ya que en los últimos años han sido habitualmente empleadas, tanto en el ámbito académico como social o político. Pero ¿podemos esperar que los efectos sean iguales en todos ellos? La obra que tiene en sus manos trata de contribuir a la respuesta de esta pregunta desde un enfoque internacional y multidisciplinar. Un amplio elenco de académicos y profesionales procedentes de países tan diversos como Colombia, Cuba, Ecuador, España, México y Uruguay, aúnan sus conocimientos para alcanzar una visión de c...
Functional advanced biopolymers have received far less attention than renewable biomass (cellulose, rubber, etc.) used for energy production. Among the most advanced biopolymers known is chitosan. The term chitosan refers to a family of polysaccharides obtained by partial de-N-acetylation from chitin, one of the most abundant renewable resources in the biosphere. Chitosan has been firmly established as having unique material properties as well as biological activities. Either in its native form or as a chemical derivative, chitosan is amenable to being processed—typically under mild conditions—into soft materials such as hydrogels, colloidal nanoparticles, or nanofibers. Given its multip...
This book explores important chapters of past and recent African history from a multidisciplinary perspective. It covers an extensive time range from the evolution of early humans to the complex cultural and genetic diversity of modern-day populations in Africa. Through a comprehensive list of chapters, the book focuses on different time-periods, geographic regions and cultural and biological aspects of human diversity across the continent. Each chapter summarises current knowledge with perspectives from a varied set of international researchers from diverse areas of expertise. The book provides a valuable resource for scholars interested in evolutionary history and human diversity in Africa. Contributors are Shaun Aron, Ananyo Choudhury, Bernard Clist, Cesar Fortes-Lima, Rosa Fregel, Jackson S. Kimambo, Faye Lander , Marlize Lombard, Fidelis T.

Esta obra constituye, sin dudas, un producto científico interesante, en el cual los autores fundamentan desde diferentes enfoques cómo es la dinámica actual de las organizaciones, donde los objetivos y propósitos centrales están encaminados a lograr la eficiencia y eficacia de los tejidos organizacionales. Desde una perspectiva innovadora, se presentan estudios que refuerzan la necesidad de visualizar sus fortalezas en el corto, mediano y largo plazo, y la búsqueda de alternativas que mejoren la capacidad de acción y la toma de decisiones adecuadas y coherentes. Se incluyen temáticas que sólo pueden abordarse a través de la investigación interdisciplinaria, y que focalizan problemas latentes tales como: la gestión de las competencias directivas, el cambio organizacional, la gestión sustentable, el emprendimiento, así como la identificación y medición del capital intelectual y la gestión presupuestaria, entre otras, donde el hilo conductor básico es afrontar los retos contemporáneos de las organizaciones bajo un crecimiento económico sostenible.
