Generació i correcció de problemes combinats

Aquest projecte forma part de la Plataforma ACME (Avaluació Continuada i Millora de l’ensenyament), un entorn virtual de resolució i correcció de problemes amb la finalitat de donar suport a les classes presencials i poder portar a terme una avaluació continuada dels alumnes. El sistema ofereix a l’alumne, a través d’Internet, una col•lecció personalitzada de problemes per assignatura, que a mida que l’alumne els resol, el sistema els corregeix automàticament, proporcionant a l’alumne un sistema de treball continu que l’ajudarà a portar l’assignatura al dia. I al professor li dóna la facilitat de fer el seguiment individualitzat de l’alumne coneixent d’aquesta manera quines són les principals dificultats que troben els alumnes, tant de manera individual com col•lectiva. L’objectiu d’aquest projecte és implementar un nou tipus de problema que ha de permetre al professor elaborar problemes que combinin diferents qüestions de igual o diferent tipologia i que quan l’alumne hagi resolt totes les qüestions, enviï les solucions juntes al sistema perquè aquest retorni el resultat global de la correcció

ACME - Mòdul d'usuaris convidats

El projecte ACME va néixer, l’any 1998, amb la finalitat de millorar la docència de les matemàtiques en els estudis d’Enginyeria Industrial i Enginyeries Tècniques de l’Escola Politècnica de la Universitat de Girona, amb la intenció de buscar la manera de que els alumnes s’impliquessin i participessin més activament en aquesta matèria fent ús de la xarxa com a via de comunicació. El projecte ACME, Avaluació Continuada i Millora de l’Ensenyament, és una eina d’e-learning que té com a objectiu fer una avaluació continuada dels alumnes a través d’uns dossiers personalitzats de problemes que el professor proposa. El sistema permet fer el seguiment, per part del professor, del progrés del conjunt de la classe, o d’un alumne individual, en una assignatura concreta. Això fa que l’ACME tingui un gran valor pedagògic. Els objectius d’aquest projecte final de carrera són els següents:• Desenvolupar un sistema de gestió d’usuaris convidats que ens permeti acceptar o denegar l’accés a usuaris que prèviament han fet una petició per poder utilitzar l’ACME.• Crear un sistema que faciliti la tasca d’assignar als usuaris els temes i els problemes més adients pel seu perfil.• Desenvolupar tot un seguit de millores i ampliacions amb la intenció d’integrar el nou mòdul dins les interfícies existents:Ampliar la interfície d’administració en l’apartat d’usuari amb la opció per gestionar els usuaris convidats. Ampliar la interfície d’administració en l’apartat del quadern de problemes amb les opcions adients per tal de gestionar les assignatures dels convidats.

Genetic diversity of EBV-encoded LMP1 in the Swiss HIV Cohort Study and implication for NF-Κb activation.

Epstein-Barr virus (EBV) is associated with several types of cancers including Hodgkin's lymphoma (HL) and nasopharyngeal carcinoma (NPC). EBV-encoded latent membrane protein 1 (LMP1), a multifunctional oncoprotein, is a powerful activator of the transcription factor NF-κB, a property that is essential for EBV-transformed lymphoblastoid cell survival. Previous studies reported LMP1 sequence variations and induction of higher NF-κB activation levels compared to the prototype B95-8 LMP1 by some variants. Here we used biopsies of EBV-associated cancers and blood of individuals included in the Swiss HIV Cohort Study (SHCS) to analyze LMP1 genetic diversity and impact of sequence variations on LMP1-mediated NF-κB activation potential. We found that a number of variants mediate higher NF-κB activation levels when compared to B95-8 LMP1 and mapped three single polymorphisms responsible for this phenotype: F106Y, I124V and F144I. F106Y was present in all LMP1 isolated in this study and its effect was variant dependent, suggesting that it was modulated by other polymorphisms. The two polymorphisms I124V and F144I were present in distinct phylogenetic groups and were linked with other specific polymorphisms nearby, I152L and D150A/L151I, respectively. The two sets of polymorphisms, I124V/I152L and F144I/D150A/L151I, which were markers of increased NF-κB activation in vitro, were not associated with EBV-associated HL in the SHCS. Taken together these results highlighted the importance of single polymorphisms for the modulation of LMP1 signaling activity and demonstrated that several groups of LMP1 variants, through distinct mutational paths, mediated enhanced NF-κB activation levels compared to B95-8 LMP1.

Technology diffusion and the spatial distribution of wages in the US

What explains the spatial distribution of wages across US counties? I find that two of the most important factors are spatial technology diffusion and externalities due to the aggregate scale of production. One empirical finding supporting the importance of spatial technology diffusion is that average wages in a county decrease with the average level of schooling in neighboring counties when employment in the county and average wages in neighboring counties are held constant. All empirical results are obtained using anovel instrument for (endogenous) employment at the county-leveland take into account other factors (e.g. productivity-differencesacross states, climate) that may determine wages.

Multinationals, technology networks and international takeovers

We formulate a knowlegde--based model of direct investment through mergers and acquisitions. M&As are realized to create comparative advantages by exploiting international synergies and appropriating local technology spillovers requiring geographical proximity, but can also represent a strategic response to the presence of a multinational rival. The takeover fee paid tends to increase with the strength of local spillovers which can thus work against multinationalization. Seller's bargaining power increases the takeover fee, but does not influence the investment decision. We characterize losers and winners from multinationalization, and show that foreign investment stimulates research but could result in a synergy trap reducing multinationals' profits.

Iowa Efficiency Review Report to Governor Chet Culver and Lieutenant Governor Patty Judge, December 18,2009

Public Works is pleased to present the following Iowa Efficiency Review Report to Governor Chet Culver and Lieutenant Governor Patty Judge. This report is the product of a collaboration between our consulting team and very dedicated Iowa state employees who worked with us to share ideas and cost‐saving proposals under very difficult circumstances caused by the national financial crisis that is affecting state budgets throughout the country. For example, during the course of this review, Iowa departments were also asked to develop across‐the‐board cuts to achieve immediate reductions in state spending. It is a credit to Iowa state government that departmental staff continued to work on this Efficiency Review Report despite these challenges of also having to develop across‐the‐board budget cuts to achieve a balanced budget. We hope that these ideas will set the stage for further future budget improvements from achieving efficiencies, eliminating outdated practices, increasing the use of information technology solutions and finding new sources of non‐tax funding. The Efficiency Review Team faced a second challenge. Statewide Efficiency Reviews usually take from nine to 12 months to complete. In Iowa, we worked with dedicated department staff to complete our work in less than 4 months. The Governor challenged all of us to work intensely and to give him our best thinking on efficiency proposals so that he could act as quickly as possible to position state government for success over the next several years.

Faktorenanalytische Untersuchung und Rehabilitätsbestimmung der statischen und dynamischen Pupillometrie bei Normalpersonen und psychopathologischen Gruppen [Factor analytic study and determination of rehabilitation of static and dynamic pupillometry in normal persons and psychopathologic groups]

Variables measured during static and dynamic pupillometry were factor-analyzed. Following factors were obtained regardless whether investigations were carried out in normals or in psychiatric patients: A static factor, a dynamic factor, a stimulus-specific factor and a restitution-dependent factor. Evaluation of reliability in normals demonstrated a high reliability for the static variables of pupillometry.
