Eficiència energètica aplicada a les instal·lacions de la Universitat de Vic

En termes generals, es pot definir l’Eficiència Energètica com la reducció del consum d’energia mantenint els mateixos serveis energètics, sense disminuir el nostre confort i qualitat de vida, protegint el medi ambient, assegurant el proveïment i fomentant un comportament Sostenible al seu ús. L’objectiu principal d’aquest treball, és reduir el consum d’energia i terme de potència contractat a la Universitat de Vic, aplicant un programa d’estalvi amb mesures correctores en el funcionament de les seves instal·lacions o espais. Per tal de poder arribar a aquest objectiu marcat, prèviament s’ha realitzat un estudi acurat, obtenint tota la informació necessària per poder aplicar les mesures correctores a la bossa més important de consum. Un cop trobada, dur a terme l’estudi de la viabilitat de la inversió de les mesures correctores més eficients, optimitzant els recursos destinats. L’espai on s’ha dut a terme l’estudi, ha estat a l’edifici F del Campus Miramarges, seguint les indicacions d’Arnau Bardolet (Cap de Manteniment de la UVIC). Aquest edifici consta d’un entresol, baixos i quatre plantes. L’equip de mesura que s’ha fet servir per realitzar l’estudi, és de la marca Circutor sèrie AR5-L, aquests equips són programables que mesuren, calculen i emmagatzemen en memòria els principals paràmetres elèctrics en xarxes trifàsiques. Els projectes futurs complementaris que es podrien realitzar a part d’aquest són: instal·lar sensors, instal·lar mòduls convertidors TCP/IP, aprofitar la xarxa intranet i crear un escada amb un sinòptic de control i gestió des d’un punt de treball. Aquest aplicatiu permet visualitzar en una pantalla d’un PC tots els estats dels elements controlats mitjançant un sinòptic (encendre/parar manualment l’enllumenat i endolls de les aules, estat d’enllumenat i endolls de les aules, consums instantanis/acumulats energètics, estat dels passadissos entre altres) i explotar les dades recollides a la base de dades. Cada espai tindria la seva lògica de funcionament automàtic específic. Entre les conclusions més rellevants obtingudes en aquest treball s’observa: · Que és pot reduir la potència contractada a la factura a l’estar per sota de la realment consumida. · Que no hi ha penalitzacions a la factura per consum de reactiva, ja que el compensador funciona correctament. · Que es pot reduir l’horari de l’inici del consum d’energia, ja que no correspon a l’activitat docent. · Els valors de la tensió i freqüència estan dintre de la normalitat. · Els harmònics estan al llindar màxim. Analitzant aquestes conclusions, voldria destacar les mesures correctores més importants que es poden dur a terme: canvi tecnològic a LED, temporitzar automàticament l’encesa i apagada dels fluorescents i equips informàtics de les aules “seguint calendari docent”, instal·lar sensors de moviment amb detecció lumínica als passadissos. Totes les conclusions extretes d’aquest treball, es poden aplicar a tots els edificis de la facultat, prèviament realitzant l’estudi individual de cadascuna, seguint els mateixos criteris per tal d’optimitzar la inversió.

Ètica per aixecar la Moral : Problemes ètics als serveis socials bàsics en temps de crisi

Els riscos ètics als serveis socials en temps de crisi es multipliquen i s’intensifiquen, però en essència no es tracta de riscos nous ni diferents dels que es podien produir en temps de bonança econòmica i social. No obstant, la cruesa del context dels serveis socials bàsics (freqüència de les situacions límit que s'han d'atendre, les qüestions internes i externes de la pràctica professional, el malestar i desencant dels professionals) pot suposar una oportunitat de visibilitat i prendre consciència d'aquests riscos ètics. A la vegada, l'anàlisi i l'abordatge d'aquest nou context des d'una perspectiva ètica pot suposar un antídot que permeti ressituar la pràctica professional (amb els seus límits, però també amb les seves possibilitats), millorar-ne la qualitat i la transparència, i, de retruc, trencar amb la dinàmica de cronificació de la insatisfacció i queixa professional. És a dir, la perspectiva ètica pot ajudar a aixecar la moral dels professionals. Així doncs, amb aquesta recerca pretenem assolir els següents objectius: Identificar els riscos ètics de la intervenció als serveis socials bàsics en relació als efectes i l'impacte de la crisi econòmica; analitzar els diferents riscos ètics identificats i efectuar propostes d'abordatge i minimització d'aquests riscos ètics

Hipertextos fragmentados: Una propuesta para trabajar la competencia lectoliteraria en la formación inicial de docentes

El canon para la formación literaria y la educación literaria en primaria son algunos de los contenidos principales de la asignatura 'Didáctica de la literatura infantil y juvenil" que se imparte en el grado de Educación Primaria de la Universitat de Barcelona. La propuesta de innovación educativa que presentamos consiste en el diseño e implementación de una secuencia formativa dirigida a estos alumnos para ampliar el intertexto lector mediante la lectura y análisis de un corpus de minificciones hipertextuales (Zavala, 2007; Landow, 2009) relacionadas con la literatura de base folklórica y de autor del canon de educación primaria de primeras lenguas. El corpus elegido pertenece al libro Catàleg de monstres (2012) de Masó, minificciones que apelan a la intertextualidad mediante la combinación de múltiples recursos literarios. Palabras clave: Formación inicial de maestros, competencia lectoliteraria, minificción, literatura infantil y juvenil. ENGLISH SUMMARY Fragmented Hypertexts: a proposal to develop literacy competence in initial teacher training Literary canon for primary children and literature education are some of the main contents of the subject 'Teaching of Children's Literature' taught in the Primary Education degree at the University of Barcelona. The proposed educational innovation we present is the design of a teaching sequence targeted to these students to expand their reader intertextuality by reading and analysing hypertext mini fictions (Zavala, 2007; Landow, 2009) related to basic folk literature from the primary school literary canon. The corpus chosen is from the book Catàleg de monstres (2012), written by Masó, selected mini fictions constantly appealing to intertextuality through the combination of multiple literarcy resources. Key words: Folk literature, teacher training of primary education, hypertext mini fictions, literary competence.

Conflicto, colaboración y consenso en la enseñanza de las ciencias sociales = Conflict, collaboration and consensus in the teaching of the Social sciences

This article suggests the study of the key concept of conflict as a means of implementing a critical and communicativecurriculum based on the study of relevant social themes. To this end we put forward the principal characteristics of thecritical/communicative curriculum. We offer a didactic proposal about conflict and explain the results of its application intwo Secondary Education classrooms

Enseñar a convivir, enseñar a comunicarse = Teaching to live together, teaching to communicate

In this article we look at some of the questions related to the learning of how to live together so that we may then look more closely at the relative aspects of the learning of language. We insist on the importance of the not strictly linguistic aspects associated to the incorporation of children from immigrant families to the schools. From this point of view we underline the heterogeneous nature of the situation in which these children find themselves (in function with the social and professional situation of the family, of having been born here or not, and of having or not previous school experience in the community of origin etc). We also look at the necessary eradication of stereo types in the treating of this problem. We then discuss some strategies where there can be joint collaboration in the school for attaining these objectives

Una visión actualizada de la didáctica de la matemática en educación infantil = An up-to-date vision of pre-school mathematics teaching

This article aims to investigate pre-school mathematics teaching from an uptodate perspective. To pursue this contemporary vision we focus on four key questions: what kind of maths is being worked on, who is doing it, how it is being done, and why it is being done

Consideraciones metodológicas para la enseñanza y el aprendizaje del deporte escolar = Methodological considerations for the teaching and learning of school sport

Sport is a fundamental content in the teaching and learning of Physical Education independently of whether it is seen assuch by some authors. In whichever case according to the treatment that we give it, it will have sufficient educationalpotential without forgetting that it is the student who is the important figure in the process. To achieve the objectives wemust facilitate practices that are in agreement with the indispensable ethical principles to try to bring about a meaningfuland functional learning. The methodological criteria that we present in this article have this intention helped by examplesthat make it easier to understand the teaching learning process

AVOIDING FIRST-YEAR UNIVERSITY CHEMISTRY TEXTBOOKS’ MISREPRESENTATIONS IN THE TEACHING OF SPONTANEOUS REACTIONS

This paper summarizes the misrepresentations related to Gibbs energy in general chemistry textbooks. These misrepresentations arise from a problem in the terminology textbooks use. Thus, after reviewing the proper definition of each of the terms analyzed, we present two problems to exemplify the correct treatment of the quantities involved, which may help in the discussion and clarification of the misleading conventions and assumptions reported in this study.

INTERACTIONS: DESIGN, IMPLEMENTATION AND EVALUATION OF A COMPUTATIONAL TOOL FOR TEACHING INTERMOLECULAR FORCES IN HIGHER EDUCATION

Intermolecular forces are a useful concept that can explain the attraction between particulate matter as well as numerous phenomena in our lives such as viscosity, solubility, drug interactions, and dyeing of fibers. However, studies show that students have difficulty understanding this important concept, which has led us to develop a free educational software in English and Portuguese. The software can be used interactively by teachers and students, thus facilitating better understanding. Professors and students, both graduate and undergraduate, were questioned about the software quality and its intuitiveness of use, facility of navigation, and pedagogical application using a Likert scale. The results led to the conclusion that the developed computer application can be characterized as an auxiliary tool to assist teachers in their lectures and students in their learning process of intermolecular forces.

Fiktiivisen kirjallisuuden maailmasta monikulttuuriseen Suomeen. Ennakointikertomus kirjallisuudenopetuksen ja monikulttuurisuuskasvatuksen välineenä

From the world of fiction literature into multi-cultural Finland. Anticipatory story as an educational tool in teaching of literature and multiculturalism The research clarifies the relationship between reading fiction literature and multicultural value education in basic education. The research focuses on the subject didactics of mother tongue and literature and on the literature teaching in particular. The objective is to develop a method that is easily transferable into a teaching context so as to intensify the educational discussion based on fiction literature. In essence, understanding fiction literature and the ethical and moral thinking resemble one another, because both of them aim at empathizing with the thinking of a person or with a situation foreign to oneself. For this reason fiction literature is ideally suited for the discussion on ethical and moral values within a subject entity in the basic education. The empirical unit of the research consists of two parts. The first part explains how youth novels published in the years 1993 – 2007 describe multiculturalism in Finnish society. Books on multiculturalism are still few in number within youth literature, and people with a foreign background are mainly minor or background characters in such literary works. Nevertheless, youth novels serve well as a starting point for an educational discussion about multicultural issues. More often than not characters in youth novels are stereotypes and even opposite to each other. The juxtaposing makes a young reader question the stereotypes associated with immigrants. Besides the stereotype, reference to a prototype or a model is possible. The second part tests the usefulness of an anticipatory story based on a fictive text for an educational discussion about multicultural issues. The empirical material was collected from the eighth-grade teaching groups in basic education as follows: one teaching group was an immigrant group, the second one a group of Finns with experience of immigrants while the third group of students had hardly any experience of immigrants. The anticipatory stories were written on the basis of extracts from youth novels with multicultural themes. The material collected for a total of 120 anticipatory stories was analysed by using meaning cue analysis. Using the meaning cue analysis, the anticipatory stories were divided into three groups: stories with predominantly positive meaning cues of interculturalism, ambivalent stories with both positive and negative meaning cues of interculturalism and the stories with predominantly negative meaning cues of interculturalism. The meaning cues produced by girls and boys differ from one another, in particular, by the negative meaning cues of interculturalism. For girls, the predominant meaning cue is fear whereas for boys, it is that of violence. It would also seem that the students, in particular, boys with little experience of immigrants produce more negative meaning cues of interculturalism than do immigrants or Finnish students with experience of immigrants. Further still, it seems that active reading of fiction literature affects the meaning cues of interculturalism in an ambivalent direction. In the way of youth novels this is understandable, because youth novels in general are made up of opposite characters and meaning cues. The less the student takes an interest in reading, the more he used meaning cues from outside the parent text for his anticipatory story. No doubt it would be possible to use fiction literature in the literature education to a much higher extent than it is being used today whereby the literature could be used in basic education for reviewing subject entities or study contents of other study subjects. By way of an anticipatory story and the meaning cue analysis, it is possible to intensify the educational discussions based on fiction literature. However, using fiction literature in the literature education requires consideration of the specific genre of fiction literature.
