Bisemivalues for bicooperative games

We introduce bisemivalues for bicooperative games and we also provide an interesting characterization of this kind of values by means of weighting coefficients in a similar way as it was given for semivalues in the context of cooperative games. Moreover, the notion of induced bisemivalues on lower cardinalities also makes sense and an adaptation of Dragan’s recurrence formula is obtained. For the particular case of (p, q)-bisemivalues, a computational procedure in terms of the multilinear extension of the game is given.Peer ReviewedPostprint (author's final draft

The Owen and the Owen-Banzhaf values applied to the study of the Madrid Assembly and the Andalusian Parliament in legislature 2015-2019

This work focuses on the Owen value and the Owen-Banzhaf value, two classical concepts of solution defined on games with structure of coalition blocks. We provide a computation procedure for these solutions based on a method of double-level work obtained from the multilinear extension of the original game. Moreover, two applications to several possible political situations in the Madrid Assembly and the Andalusian Parliament (legislatures 2015-2019) are also given.Peer ReviewedPostprint (published version

A method to calculate generalized mixed modified semivalues: application to the Catalan Parliament (legislature 2012-2016)

The final publication is available at Springer via http://dx.doi.org/10.1007/s11750-014-0356-6”.We focus on generalized mixed modified semivalues, a family of coalitional values. They apply to games with a coalition structure by combining a (induced) semivalue in the quotient game, but share within each union the payoff so obtained by applying different (induced) semivalues to a game that concerns only the players of that union. A computation procedure in terms of the multilinear extension of the original game is also provided and an application to the Catalan Parliament (legislature 2012-2016) is shownPeer ReviewedPostprint (published version

Sistemas de tratamiento de remoción de nitrógeno y fósforo, en efluentes de industrias de la Cuenca del Río Santa Lucía

Como parte de la tesis se realizó un exhaustivo relevamiento, análisis y evaluación, de los sistemas de lodos activados implementados por 5 industrias, las condiciones que fueron previstas en el diseño, y los resultados de su operación. Parte de los objetivos consistieron en evaluar la aptitud para alcanzar los estándares exigidos por normativa, y evaluar los principales parámetros de diseño (SRT, Producción específica de lodos, carga de lodos, Índice de Sedimentabilidad de Lodos, entre otros). En particular analizar si los valores/rangos que se tomaron como referencia para los parámetros de diseño, se confirmaban luego en la operación, verificando en ese caso, que se adecuaban a las condiciones previstas en el diseño. Como parte del análisis, y de manera de poder comparar con la misma base, se propuso como metodología para relevar los parámetros de diseño, un algoritmo basado en la guía (ATV-A 131, 2001). Por lo tanto parte del estudio consistió en relevar si era posible el uso de dicha metodología, dado que si bien es ampliamente utilizada a nivel mundial, se aplica en circunstancias diferentes. A la luz de los resultados obtenidos en 12-24 meses de operación, la primera conclusión es que los sistemas de lodos activados implementados han sido exitosos, dado que el efluente de salida cumple con las nuevas exigencias de nitrógeno y fósforo; verificándose en cada uno de las configuraciones implementadas por las industrias, las ventajas operativas que predecía la bibliografía. En relación a los valores de los parámetros de diseño, cabe aclarar que hasta el momento se tiene un período acotado de operación y por tal motivo no corresponde a un análisis estadístico, pero de una manera general, se concluye que la metodología propuesta puede emplearse. Como próximo e inmediato paso, se plantea que debe evaluarse cómo definir las condiciones de operación que– sin comprometer la sostenibilidad - minimicen los costos de la operación de los sistemas de lodos activados. Asimismo, a los efectos del diseño, deberá planificarse estudios y mediciones, tendientes a validar el uso de la metodología, y los rangos a tomar como referencia para los parámetros fundamentales

Handy or practical student. Objective: to pass or to learn

With the introduction of the European Higher Education Area and the development of the "Bologna" method in learning certain technological subjects, a pilot assessment procedure was launched in the "old" plan to observe, monitor and analyze the acquiring knowledge of senior students in various academic courses. This paper is a reflection on culture and knowledge. Will students accommodate to get a lower score on tests because they know they have a lot of tooltips to achieve their objectives?. Are their skills lower for these reason?

Traditional education vs modern education. What is the impact of teaching techniques' evolution on students learning process?

The main objective of this article is to focus on the analysis of teaching techniques, ranging from the use of the blackboard and chalk in old traditional classes, using slides and overhead projectors in the eighties and use of presentation software in the nineties, to the video, electronic board and network resources nowadays. Furthermore, all the aforementioned, is viewed under the different mentalities in which the teacher conditions the student using the new teaching technique, improving soft skills but maybe leading either to encouragement or disinterest, and including the lack of educational knowledge consolidation at scientific, technology and specific levels. In the same way, we study the process of adaptation required for teachers, the differences in the processes of information transfer and education towards the student, and even the existence of teachers who are not any longer appealed by their work due which has become much simpler due to new technologies and the greater ease in the development of classes due to the criteria described on the new Grade Programs adopted by the European Higher Education Area. Moreover, it is also intended to understand the evolution of students’ profiles, from the eighties to present time, in order to understand certain attitudes, behaviours, accomplishments and acknowledgements acquired over the semesters within the degree Programs. As an Educational Innovation Group, another key question also arises. What will be the learning techniques in the future?. How these evolving matters will affect both positively and negatively on the mentality, attitude, behaviour, learning, achievement of goals and satisfaction levels of all elements involved in universities’ education? Clearly, this evolution from chalk to the electronic board, the three-dimensional view of our works and their sequence, greatly facilitates the understanding and adaptation later on to the business world, but does not answer to the unknowns regarding the knowledge and the full development of achievement’s indicators in basic skills of a degree. This is the underlying question which steers the roots of the presented research

The history of technology in education. A comparative study and forecast

Area, launched in 1999 with the Bologna Declaration, has bestowed such a magnitude and unprecedented agility to the transformation process undertaken by European universities. However, the change has been more profound and drastic with regards to the use of new technologies both inside and outside the classroom. This article focuses on the study and analysis of the technology’s history within the university education and its impact on teachers, students and teaching methods. All the elements that have been significant and innovative throughout the history inside the teaching process have been analyzed, from the use of blackboard and chalk during lectures, the use of slide projectors and transparent slides, to the use of electronic whiteboards and Internet nowadays. The study is complemented with two types of surveys that have been performed among teachers and students during the school years 1999 - 2011 in the School of Civil Engineering at the Polytechnic University of Madrid. The pros and cons of each of the techniques and methodologies used in the learning process over the last decades are described, unfolding how they have affected the teacher, who has evolved from writing on a whiteboard to project onto a screen, the student, who has evolved from taking handwritten notes to download information or search the Internet, and the educational process, that has evolved from the lecture to acollaborative learning and project-based learning. It is unknown how the process of learning will evolve in the future, but we do know the consequences that some of the multimedia technologies are having on teachers, students and the learning process. It is our goal as teachers to keep ourselves up to date, in order to offer the student adequate technical content, while providing proper motivation through the use of new technologies. The study provides a forecast in the evolution of multimedia within the classroom and the renewal of the education process, which in our view, will set the basis for future learning process within the context of this new interactive era

Failures of harbour walls at Malaga and Barcelona

The paper describes the failure of harbour walls which occurred at Malaga on 4th July 2004 and at Barcelona on 1st January 2007, associated with an inadequate consideration of the ground conditions in the light of the marine environment. At Malaga, there was an existing breakwater hence the new harbour was protected from the effect of the waves while at Barcelona, the construction of the quay wall proceeded at a faster rate than the breakwater. In both cases the wharf backfill was placed rapidly on the soft muds, progressing from the inland side. The paper discusses the importance of an overview including the ground investigation, engineering design, construction method and speed of construction

Use and abuse of audivisual media in the college classroom. Slides show and web pages

The multimedia development that has taken place within the university classrooms in recent years has caused a revolution at psychological level within the collectivity of students and teachers inside and outside the classrooms. The slide show applications have become a key supporting element for university professors, who, in many cases, rely blindly in the use of them for teaching. Additionally, ill-conceived slides, poorly structured and with a vast amount of multimedia content, can be the basis of a faulty communication between teacher and student, which is overwhelmed by the appearance and presentation, neglecting their content. The same applies to web pages. This paper focuses on the study and analysis of the impact caused in the process of teaching and learning by the slide show presentations and web pages, and its positive and negative influence on the student’s learning process, paying particular attention to the consequences on the level of attention within the classroom, and on the study outside the classroom. The study is performed by means of a qualitative analysis of student surveys conducted during the last 8 school Civil Engineering School at the Polytechnic University of Madrid. It presents some of the weaknesses of multimedia material, including the difficulties for students to study them, because of the many distractions they face and the need for incentives web pages offer, or the insignificant content and shallowness of the studies due to wrongly formulated presentations
