"Solo la muerte o la cárcel son capaces de arrancarles su poder. Los "grandes" líderes sindicales de México son lo que parecen ylo que aparentan: viejos dictadores, caciques depredadores, cínicosderrochadores. Una relación perversa con el poder les ha permitidoforjar una gerontocracia tan profundamente antidemocrática queno admite crítica, y se adapta a cualquier escenario, situación oideología. Por ellos, en México parece practicarse una sola políticalaboral: la del cinismo, abundancia para unos cuantos privilegiados; pobreza, carestía e inflación para los más. Los amos de la mafia sindical rescata ocho historias de largaduración que muestran no solo a los ocho dirigentes más poderosos del país, sino las perversiones y deformaciones de una burocracia sindical que se queda con la enorme fortuna de las cuotas de sus agremiados, sobre las cuales no hay transparencia ni control. Y aunque hay varios más, estos ocho pintan la triste y compleja historia de una realidad."--P. [4] of cover

"Enrique Peña Nieto ha forjado su propia casta política. Desde 2009 empezó a formar en todo el país un círculo de políticos bonitos y telegénicos afines: gobernadores, senadores, diputados y dirigentes del PRI, que en 2011 darían forma a una versión muy refinada de aquellos Golden Boys de 1999, cuyo líder era el mismo Peña Nieto. Al margen de cualquier calificativo -- juniors, metrosexuales conservadores, guapos sin sensibilidad o yuppies excluyentes -- , tras este jet set de política mexicana emerge el trasfondo de un grupo que arroja múltiples evidencias del regreso inquietante del PRI, donde se incluye lo mismo a tecnócratas que a dinosaurios. A esta nueva élite se han sumado empresarios, "centauros" -- políticos-empresarios -- , y jerarcas de la Iglesia católica mexicana. Todos ellos son quienes ilustran mejor la vida y obra política del nuevo inquilino de Palacio Nacional." --P. [4] of cover

Spain is currently facing its worst crisis in the last fifty years. The
crisis began as an extension of the international financial crisis, but the
internal imbalances accumulated in the pre-crisis period aggravated the
situation. At present their incomplete adjustment is making difficult the
economic recovery. This paper describes the evolution of the economic crisis
in Spain. The real estate sector and the banking sector are analyzed in
detail, as they played a key role in the detonation and the deepening of the
crisis. The results of the main reforms carried out so far are also carefully
examined. It also discusses the main factors that have delayed the economic
recovery up to now (unemployment and indebtedness), and present some
alternatives to define an exit strategy.

El éxito de las organizaciones tiene que ver, por supuesto, con la calidad de su gestión, de la calidad de los productos y servicios que ofrece, de su personal, en fin, de los diversos y complejos elementos y procesos de sus sistemas internos. Sin embargo también es determinante la calidad del entorno donde se inserta la empresa. Lugares de alta calidad, con una sociedad culta, organizada, solidaria, con elevados niveles de confianza, y que cuenta con un sector público eficaz, honesto, que establece reglas claras y las cumple, que tienen procedimiento sencillos y trasparentes, seguramente son proclives a contar con organizaciones exitosas. En cambio en lugares con graves déficit de capital social y gobiernos corrompidos, la creación de empresas exitosas es más difícil. ; The success of organizations has to do with, of course, the quality of their management, with the quality of the products and services thy offers, of their personnel, in the end, with the diverse and complex elements and processes of its internal systems. However, the quality of the environment where the business is located is also determining places of high quality, with an educated, organized, unified, honest society with high levels of trust, and that count on an efficient public sector, that establishes clear rules and follows them ,that have simple and transparent procedures, surely are likely to count on successful organizations. On the other hand, in places with serious social capital deficit and corrupt governments, the creation of successful businesses is more difficult. ; 11-20 ; rectorado@uvm.edu.ve

A introdução de taxas ambientais sobre o transporte aéreo tem sido reclamada por certos sectores sociais e alguns governos, com a finalidade de que os preços dos bilhetes reflictam a totalidade dos custos externos gerados por esta actividade de transporte. Neste artigo revê-se uma metodologia para o cálculo de Taxas Ambientais Aeroportuárias (TAA), com base nas externalidades associadas à perturbação por ruído e às emissões de carácter local. Ademais, estimam-se as taxas potencialmente aplicáveis no Aeroporto da Portela por tipo de avião. No caso do ruído utilizam-se custos marginais, enquanto que no caso das emissões poluentes são empregues custos médios. Recorre-se preferentemente à transferência de benefícios, utilizando, sempre que possível, valores específicos para Portugal. A metodologia empregue prova a exequibilidade do cálculo destas taxas e revela que a correcta aplicação das mesmas implica ter em consideração, tanto as especificidades de cada aeroporto como a composição da frota que nele opera.

One of the main challenges when training or fine-tuning a machine learning model concerns the number of observations necessary to achieve satisfactory performance. While, in general, more training observations result in a better-performing model, collecting more data can be time-consuming, expensive, or even impossible. For this reason, investigating the relationship between the dataset's size and the performance of a machine learning model is fundamental to deciding, with a certain likelihood, the minimum number of observations that are necessary to ensure a satisfactory-performing model is obtained as a result of the training process. The learning curve represents the relationship between the dataset's size and the performance of the model and is especially useful when choosing a model for a specific task or planning the annotation work of a dataset. Thus, the purpose of this paper is to find the functions that best fit the learning curves of a Transformers-based model (LayoutLM) when fine-tuned to extract information from invoices. Two new datasets of invoices are made available for such a task. Combined with a third dataset already available online, 22 sub-datasets are defined, and their learning curves are plotted based on cross-validation results. The functions are fit using a non-linear least squares technique. The results show that both a bi-asymptotic and a Morgan-Mercer-Flodin function fit the learning curves extremely well. Also, an empirical relation is presented to predict the learning curve from a single parameter that may be easily obtained in the early stage of the annotation process.
