La presente investigación tuvo como objetivo determinar los factores que se encuentran asociados al rendimiento académico de los estudiantes. Para este propósito se empleó el enfoque cuantitativo, se ubicó en el diseño no experimental, transversal y descriptiva correlacional. La investigación tuvo una población de 54 estudiantes de estudios generales de una escuela profesional de una universidad pública matriculados en el año en curso al desarrollo de la investigación. Para calcular el tamaño de muestra se utilizó el diseño de muestreo aleatorio irrestricto dando como resultado 19 y 15 estudiantes de II Y IV ciclo respectivamente. Las técnicas estadísticas empleadas para este...
This eBook is a collection of articles from a Frontiers Research Topic. Frontiers Research Topics are very popular trademarks of the Frontiers Journals Series: they are collections of at least ten articles, all centered on a particular subject. With their unique mix of varied contributions from Original Research to Review Articles, Frontiers Research Topics unify the most influential researchers, the latest key findings and historical advances in a hot research area! Find out more on how to host your own Frontiers Research Topic or contribute to one as an author by contacting the Frontiers Editorial Office: frontiersin.org/about/contact.
This handbook presents an overview of studies on the relationship of active ageing and quality of life. It addresses the new challenges of ageing from the paradigm of positive ageing (active, healthy and successful) for a better quality of life. It provides theoretical perspectives and empirical studies, including scientific knowledge as well as practical experiences about the good ageing and the quality of later life around the world, in order to respond to the challenges of an aged population. The handbook is structured in 4 sections covering theoretical and conceptual perspectives, social policy issues and research agenda, methods, measurement instrument-scales and evaluations, and lastly application studies including domains and geographical contexts. Chapter 5 is available open access under a Creative Commons Attribution 4.0 International License via link.springer.com./div
This book contains the summaries of the "Innovation in Pharmacy: Advances and Perspectives" that took place in Salamanca (Spain) in September 2018. The early science of chemistry and microbiology were the source of most drugs until the revolution of genetic engineering in the mid 1970s. Then biotechnology made available novel protein agents such as interferons, blood factors and monoclonal antibodies that have changed the modern pharmacy. Over the past year, a new pharmacy of oligonucleotides has emerged from the science of gene expression such as RNA splicing and RNA interference. The ability to design therapeutic agents from genomic sequences will transform treatment for many diseases. The...
Enabling the Business of Agriculture 2019 presents indicators that measure the laws, regulations and bureaucratic processes that affect farmers in 101 countries. The study covers eight thematic areas: supplying seed, registering fertilizer, securing water, registering machinery, sustaining livestock, protecting plant health, trading food and accessing finance. The report highlights global best performers and countries that made the most significant regulatory improvements in support of farmers.
En esta publicación se recogen los trabajos presentados en el XXI Congreso Nacional de Historia del Arte (CEHA), celebrado en el Palacio de la Magdalena de Santander entre los días 20 al 23de septiembre de 2016. El eje vertebrador de dicho congreso giró en torno a una temática a la vez monográfica y transversal: LA FORMACIÓN ARTÍSTICA. Se aborda este objetivo desde la doble perspectiva que plantean los dos protagonistas principales del diálogo artístico (el creador y el espectador), pasando por el historiador del arte como mediador entre ambos. Empleando este hilo conductor, se traza el rico panorama investigador nacional, tratando de reflejar las principales orientaciones metodológicas de la disciplina, así como las líneas de trabajo más consolidadas y las emergentes. Las aportaciones en cada uno de los seis bloques (desde el gremio, la formación académica o la universitaria, la educación de la mirada, la crisis de la Historia del Arte, las fuentes, la historiografía y la literatura artística y, por último, el dedicado a proyectos, tesis y grupos de I+D+i) presentan una visión actualizada de algunas de las tendencias de la investigación en Historia del Arte.
This book covers both the fundamental and applied aspects of advanced Na-ion batteries (NIB) which have proven to be a potential challenger to Li-ion batteries. Both the chemistry and design of positive and negative electrode materials are examined. In NIB, the electrolyte is also a crucial part of the batteries and the recent research, showing a possible alternative to classical electrolytes – with the development of ionic liquid-based electrolytes – is also explored. Cycling performance in NIB is also strongly associated with the quality of the electrode-electrolyte interface, where electrolyte degradation takes place; thus, Na-ion Batteries details the recent achievements in furthering knowledge of this interface. Finally, as the ultimate goal is commercialization of this new electrical storage technology, the last chapters are dedicated to the industrial point of view, given by two startup companies, who developed two different NIB chemistries for complementary applications and markets.
Praised by some as islands of efficiency in a sea of unprofessional, politicized, and corrupt states, and criticized by others for removing wide areas of policy making from the democratic arena, technocrats have become prominent and controversial actors in Latin American politics. Through an in-depth analysis of economic and health policy in Colombia from 1958 to 2011 and in Peru from 1980 to 2011, Technocracy and Democracy in Latin America explains the source of these experts' power as well as the leverage they have across state policy sectors in Latin America.
