Tensión Creativa aplicada al Análisis de Competencias a Alumnos de Ingeniería

This article reflects the analysis of personal and social competences through the study and analysis of creative tensión in engineering students, using a computer application called Cycloid. The main objective was to compare the students' creative tensión by asigning them the task of being the project leader of a given project: their own university major. The process consisted of evaluating, through special surveys, a group of students to know the current situation of competences, using fuzzy logic analysis. From this self-knowledge, provided by the survey, students can know their strong and weak characteristics regarding their study habits. Results showed that tolerance to stress and to language courses are the weaker points. This application is useful for the design of study strategies that students themselves can do to better face their courses

Building legitimacy by criticising the pharmaceutical industry: a qualitative study among prescribers and local opinion leaders.

PRINCIPLES: The literature has described opinion leaders not only as marketing tools of the pharmaceutical industry, but also as educators promoting good clinical practice. This qualitative study addresses the distinction between the opinion-leader-as-marketing-tool and the opinion-leader-as-educator, as it is revealed in the discourses of physicians and experts, focusing on the prescription of antidepressants. We explore the relational dynamic between physicians, opinion leaders and the pharmaceutical industry in an area of French-speaking Switzerland. METHODS: Qualitative content analysis of 24 semistructured interviews with physicians and local experts in psychopharmacology, complemented by direct observation of educational events led by the experts, which were all sponsored by various pharmaceutical companies. RESULTS: Both physicians and experts were critical of the pharmaceutical industry and its use of opinion leaders. Local experts, in contrast, were perceived by the physicians as critical of the industry and, therefore, as a legitimate source of information. Local experts did not consider themselves opinion leaders and argued that they remained intellectually independent from the industry. Field observations confirmed that local experts criticised the industry at continuing medical education events. CONCLUSIONS: Local experts were vocal critics of the industry, which nevertheless sponsor their continuing education. This critical attitude enhanced their credibility in the eyes of the prescribing physicians. We discuss how the experts, despite their critical attitude, might still be beneficial to the industry's interests.

Isoelectric focusing of urinary metallothionein.

Isoelectric focusing of human urinary metallothionein at a pH range of 4.8 to 7.0 yielded a single protein band with a pI of 5.57 which co-migrated with authentic purified metallothionein I from human liver. Minimum pretreatment of the urine samples (160 ml) was needed. The preparatory steps included sample concentration with the original protein, enriched from 69 +/- 23 micrograms/ml to 2.0 +/- 1.4 mg/ml (+/- SD; n = 9), followed by heat treatment at 80 degrees C for 5 min (2.4 +/- 1.7 mg protein/ml). After focusing, the gels were stained with silver and the lanes were scanned with a laser scanner. Peak areas were used for quantitation with commercial beta 2-microglobulin as a standard. The urinary metallothionein ranged from 1.0 to 2.6 nmol/mmol creatinine, which is comparable with values reached by radio-immunoassay.

The Evolution of the European Regulatory Framework for Electronic Communications

The paper reviews the historical transformation of the European regulatory framework for electronic communications from the era dominated by state-owned enterprises to the presence of regulated competition. In the course of these developments, the vision of the roles of the public and private sectors in electronic communications changed in expected and unexpected ways. While the period is characterized by a shift toward less direct state intervention, the intensity of regulation has increased in many areas. Most recently, in the wake of the financial crisis, new forms of state intervention can be observed, including public investment in communications infrastructure and public-private partnerships. As a result of the reforms, Europe has been able to achieve major successes but it also suffered unanticipated setbacks compared to other regions. The European Union emerged as the global leader in mobile communications during the 1990s and was able to roll-out first-generation broadband access networks more rapidly than many of its peers. Recently, however, Europe as a whole has not performed as well in deploying next-generation networks and advanced mobile communications services. The paper offers a political-economic explanation for these developments and assesses their effects on the performance of the European electronic communications sector and the economy. From this analysis, the European model emerges as a unique institutional arrangement with peculiar advantages and disadvantages. Once these are recognized, sensible next steps to build the strengths while avoiding the weaknesses of the model can be seen more clearly.

Taloushallinnon toimintastrategia

Tämän tutkimuksen tavoitteena on luoda taloushallinnon toimintastrategia voimakkaasti kasvavalle huonekalualan vähittäiskauppakonsernille. Tavoitteena oli tutkia kasvua ja sen vaikutusta yrityksen taloushallinnon prosesseihin sekä luoda toimiva prosessi kasvun eri vaiheisiin. Tutkimus luokitellaan toimintatutkimukseksi, jonka tavoitteena on kehittää toimintoja tutkimuksen aikana ja sen jälkeen. Tutkimuksen teoriaosassa tarkastellaan kasvua käsitteenä sekä kasvun vaikutuksia yrityksen toimintoihin ja johtamiseen. Toisessa vaiheessa tutustutaan huonekalujen vähittäiskauppaan toimialana sekä luodaan katsaus alan tulevaisuudennäkymiin muuttuvassa liiketoimintaympäristössä. Tämän lisäksi tutkitaan taloushallinnon muuttuneita haasteita yleisesti sekä kasvun tuomia lisähaasteita taloushallinnon toiminnoille. Aineiston perusteella voidaan todeta, että kasvu aiheuttaa yritykselle ja sen johtamiselle aina lisää haasteita. Johdon on kyettävä sopeuttamaan yrityksen toimintoja kuhunkin kasvuvaiheeseen dynaamisessa liiketoimintaympäristössä, jossa pysyvää on vain muutos. Yrityksen kasvaessa toiminnot väistämättä ammattimaistuvat ja institutionaalistuvat, niin myös taloushallinnon johtaminen ja prosessit. Taloushallinnon on pystyttävä toimimaan johdon tukena ja sparraajana kaikissa liiketoimintapäätöksissä. Talousjohdon tehtävänä on myös toimia organisaatiossa taloudellisen tietämyksen levittäjänä ja valmentajana.

L'informatique: un outil remarquable pour l'enseignement de la médecine interne générale [The informatics: a remarkable tool for teaching general internal medicine].

INTERMED training implies a three week course, integrated in the "primary care module" for medical students in the first master year at the school of medicine in Lausanne. INTERMED uses an innovative teaching method based on repetitive sequences of e-learning-based individual learning followed by collaborative learning activities in teams, named Team-based learning (TBL). The e-learning takes place in a web-based virtual learning environment using a series of interactive multimedia virtual patients. By using INTERMED students go through a complete medical encounter applying clinical reasoning and choosing the diagnostic and therapeutic approach. INTERMED offers an authentic experience in an engaging and safe environment where errors are allowed and without consequences.

De ratones y hombres. Maus, de Art Spiegelman

This article analyses the cómic book Maus, by Art Spiegelman (1986-1991), from two angles: as a work of art dealing with the Holocaust, and as a cómic that subverts the fictional tradition of the genre, opening itself up to history and the narration of reality. Maus, the first cómic book to treat the topic of the Holocaust in depth, was written by a second-generation witness. It is a story of both physical survival and enduring trauma in the family. At the same time, an analysis of the stratevival and enduring trauma in the family. At the same time, an analysis of the strateof the traditional cómic reveals how Spiegelman has used the genre to recount, instead of fiction and for the first time, a historically authentic biographical tale

Integración de recursos digitales en las tareas de aprendizaje de lenguas: portafolios electrónicos y traducción asistida por ordenador

Las herramientas informáticas abren un amplio campo de posibilidades pedagógicas a las asignaturas de lengua. En el presente artículo se propone un modelo de combinación de recursos digitales (portafolios electrónicos y traducción asistida por ordenador) que refuerzan proyectos docentes del ámbito de las lenguas desde un enfoque pedagógico socioconstructivista. En algunos casos, las actividades se pueden integrar en proyectos reales. Por otra parte, los proyectos relacionados con el uso de estas herramientas pueden tener un enfoque multidisciplinar que implique tanto a los departamentos de las lenguas extranjeras y como a los de las lenguas maternas.

A cognitive hierarchy model of behavior in the action commitment game

We apply the cognitive hierarchy model of Camerer et al. (Q J Econ 119(3):861-898, 2004)-where players have different levels of reasoning-to Huck et al. (Games Econ Behav 38:240-264, 2002) discrete version of Hamilton and Slutsky (Games Econ Behav 2:29-46, 1990) action commitment game-a duopoly with endogenous timing of entry. We show that, for an empirically reasonable average number of thinking steps, the model rules out Stackelberg equilibria, generates Cournot outcomes including delay, and outcomes where the first mover commits to a quantity higher than Cournot but lower than Stackelberg leader. We show that a cognitive hierarchy model with quantal responses can explain the most important features of the experimental data on the action commitment game in (2002). In order to gauge the success of the model in fitting the data, we compare it to a noisy Nash model. We find that the cognitive hierarchy model with quantal responses fits the data better than the noisy Nash model.

Emmy Noether: her heritage

Emmy Noether is my role model for the following reasons. She is one of the most important mathematician and physicists of the 20 century; She fought to be a scientist in times where women were not allowed to be one; She was a leader that gathered around her a large school of students and collaborators. In the lecture these reasons will be substantiated with historical facts. In addition, a general assessment of the significance of her ideas and works, from her times until today, will be advanced.

Controle de autenticidade de óleos de copaíba comerciais por cromatografia gasosa de alta resolução

Copaiba oil is a resin extracted from the trunk of trees of Copaifera species which grow in Brazil where it is widely used in popular medicine as an anti-inflammatory, antiseptic anti-bactericidal, diuretic, dermatological, expectorant, and anti-infective. The comparative study of the composition of commercial copaiba oils was carried out by high resolution gas chromatography (HRGC) and high resolution gas chromatography-mass spectrometry (HRGC-MS) analysis. The commercial oils were compared with authentic oils, collected from the southeast and northern regions of Brazil. Sixteen commercial oils were analysed and two of them revealed adulterations with fatty acids. Using the chromatographic profile of authentic copaiba species oils, it is possible to analyse commercial oils and determine the authenticity of these materials.

Human Capital Composition and Economic Growth at a Regional Level

With this paper we build a two-region model where both innovation and imitation are performed. In particular imitation takes the form of technological spillovers that lagging regions may exploit given certain human capital conditions. We show how the high skill content of each region’s workforce (rather than the average human capital stock) is crucial to determine convergence towards the income level of the leader region and to exploit the technological spillovers coming from the frontier. The same applies to bureaucratic/institutional quality which are conductive to higher growth in the long run. We test successfully our theoretical result over Spanish regions for the period between 1960 and 1997. We exploit system GMM estimators which allow us to correctly deal with endogeneity problems and small sample bias.

Appropriate IPRs, Human Capital Composition and Economic Growth

We generalize a standard technology diffusion model by allowing for IPRs regimes to be endogenously defined by the development level of each country. Also we insert differences in the composition of human capital between North (leader) and South (followers) which shape the relative costs of innovation and imitation. Results show how an optimal growth trajectory is found for the follower country which initially imitates and that, once a "threshold development stage" is reached, optimally switches to innovation by fully enforcing IPRs achieving a higher proximity with the technology frontier in the long-run. Other scenarios, such as a premature increase in the enforcement of IPRs or a switch from imitation to innovation at early stages of development of the followers are found to be sub-optimal.

Argumentos para los futuros maestros en torno al conocimiento matemático

Departing from initial training on Mathematics teaching, this article analyses several beliefs held by future teachers regarding mathematical knowledge. Some of these beliefs are an authentic obstacle for an advance towards quality Mathematics teaching, therefor, the autors reproduce five arguments given to groups of future teachers in order to tackle some of their beliefs on Mathematics and making them build, modify or consolidate a more complex imatge of mathematical knowledge and Mathematics work in the classroom

The effects of ICT on school: teachers’ and students’ perspectives

The purpose of this study was to investigate the effects of information and communication technology (ICT) on school from teachers’ and students’ perspectives. The focus was on three main subject matters: on ICT use and competence, on teacher and school community, and on learning environment and teaching practices. The study is closely connected to the national educational policy which has aimed strongly at supporting the implementation of ICT in pedagogical practices at all institutional levels. The phenomena were investigated using a mixed methods approach. The qualitative data from three cases studies and the quantitative data from three statistical studies were combined. In this study, mixed methods were used to investigate the complex phenomena from various stakeholders’ points of view, and to support validation by combining different perspectives in order to give a fuller and more complete picture of the phenomena. The data were used in a complementary manner. The results indicate that the technical resources for using ICT both at school and at homes are very good. In general, students are capable and motivated users of new technology; these skills and attitudes are mainly based on home resources and leisuretime use. Students have the skills to use new kinds of applications and new forms of technology, and their ICT skills are wide, although not necessarily adequate; the working habits might be ineffective and even wrong. Some students have a special kind of ICT-related adaptive expertise which develops in a beneficial interaction between school guidance and challenges, and individual interest and activity. Teachers’ skills are more heterogeneous. The large majority of teachers have sufficient skills for everyday and routine working practices, but many of them still have difficulties in finding a meaningful pedagogical use for technology. The intensive case study indicated that for the majority of teachers the intensive ICT projects offer a possibility for learning new skills and competences intertwined in the work, often also supported by external experts and a collaborative teacher community; a possibility that “ordinary” teachers usually do not have. Further, teachers’ good ICT competence help them to adopt new pedagogical practices and integrate ICT in a meaningful way. The genders differ in their use of and skills in ICT: males show better skills especially in purely technical issues also in schools and classrooms, whereas female students and younger female teachers use ICT in their ordinary practices quite naturally. With time, the technology has become less technical and its communication and creation affordances have become stronger, easier to use, more popular and motivating, all of which has increased female interest in the technology. There is a generation gap in ICT use and competence between teachers and students. This is apparent especially in the ICT-related pedagogical practices in the majority of schools. The new digital affordances not only replace some previous practices; the new functionalities change many of our existing conceptions, values, attitudes and practices. The very different conceptions that generations have about technology leads, in the worst case, to a digital gap in education; the technology used in school is boring and ineffective compared to the ICT use outside school, and it does not provide the competence needed for using advanced technology in learning. The results indicate that in schools which have special ICT projects (“ICT pilot schools”) for improving pedagogy, these have led to true changes in teaching practices. Many teachers adopted student-centred and collaborative, inquiry-oriented teaching practices as well as practices that supported students' authentic activities, independent work, knowledge building, and students' responsibility. This is, indeed, strongly dependent on the ICT-related pedagogical competence of the teacher. However, the daily practices of some teachers still reflected a rather traditional teacher-centred approach. As a matter of fact, very few teachers ever represented solely, e.g. the knowledge building approach; teachers used various approaches or mixed them, based on the situation, teaching and learning goals, and on their pedagogical and technical competence. In general, changes towards pedagogical improvements even in wellorganised developmental projects are slow. As a result, there are two kinds of ICT stories: successful “ICT pilot schools” with pedagogical innovations related to ICT and with school community level agreement about the visions and aims, and “ordinary schools”, which have no particular interest in or external support for using ICT for improvement, and in which ICT is used in a more routine way, and as a tool for individual teachers, not for the school community.
