La concepció política de la mediació cultural

La mediació cultural és una figura institucionalitzada a Quebec, però força desconeguda a Catalunya. A través de les pràctiques culturals busca fomentar una participació civíca ciutadana, millorar la cohesió social i el risc d'exclusió. Aquest treball investiga la mediació cultural des d'una perspectiva política, defensant que hi ha tres formes de percebre un acte de mediació. Metodològicament, s'analitzen pràctiques de mediació cultural a Montreal utilitzant com a marc interpretatiu tres models de ciutadania: liberal, comunitarista i republicà.

Detecting the oxidative reactivity of nanoparticles: a new protocol for reducing artifacts

Understanding the oxidative reactivity of nanoparticles (NPs; <100 nm) could substantially contribute to explaining their toxicity. We attempted to refine the use of 2′7-dichlorodihydrofluorescein (DCFH) to characterize NP generation of reactive oxygen species (ROS). Several fluorescent probes have been applied to testing oxidative reactivity, but despite DCFH being one of the most popular for the detection of ROS, when it has been applied to NPs there have been an unexplainably wide variability in results. Without a uniform methodology, validating even robust results is impossible. This study, therefore, identified sources of conflicting results and investigated ways of reducing occurrence of artificial results. Existing techniques were tested and combined (using their most desirable features) to form a more reliable method for the measurement of NP reactivity in aqueous dispersions. We also investigated suitable sample ranges necessary to determine generation of ROS. Specifically, ultrafiltration and time-resolved scan absorbance spectra were used to study possible optical interference when using high sample concentrations. Robust results were achieved at a 5 µM DCFH working solution with 0.5 unit/mL horseradish peroxidase (HRP) dissolved in ethanol. Sonication in DCFH-HRP working solution provided more stable data with a relatively clean background. Optimal particle concentration depends on the type of NP and in general was in the µg/mL range. Major reasons for previously reported conflicting results due to interference were different experimental approaches and NP sample concentrations. The protocol presented here could form the basis of a standardized method for applying DCFH to detect generation of ROS by NPs.

Proceedings of the 2014 Iowa Tribal Summit on Cultural Preservation and Transportation, 2014

The 2014 Iowa Tribal Summit on Cultural Preservation and Transportation was a three day event held in Ames, Iowa, where Tribal officials, transportation officials, and preservation partners sat down to discuss various topics of interest related to consultation under the National Historical Preservation Act. The goal of this Summit was for these groups to discuss and develop effective project consultation. These proceeding provide a summary of the event, as well as recommendations for how to approach similar events in the future. In sum, 13 tribal officials, 16 transportation officials, 10 preservation partners, and two moderators attended all parts of the Summit. The 2014 Summit was a successful event when assessed in terms of group participation and attendee feedback. However, all attendees agree that events such as this Summit are most effective when they occur on a somewhat regular basis, where consulting parties can have regular dialog and interaction regarding all aspects of consultation under the National Historical Preservation Act. Recommendations offered herein can be applied to various consultation situations. -- Summary, page iii

Diversitat cultural i matemàtiques

En aquesta recerca es presenten els resultats i les conclusions d’unes entrevistes realitzades a pares i mares d’alumnes de quart de primària de diferents orígens culturals, amb l’objectiu de descobrir el valor que cada família dóna a les matemàtiques, d’observar amb quines dificultats es troben els pares i mares quan han d’ajudar als seus fills i filles a fer els deures de matemàtiques, a més d’esbrinar quins recursos i/o estratègies tenen per ajudar-los. Per altra banda, també es vol saber si les experiències que tenen els adults en relació amb les matemàtiques afecta a l’ensenyament-aprenentatge dels seus fills i filles.

EEG windowed statistical wavelet scoring for evaluation and discrimination of muscular artifacts

EEG recordings are usually corrupted by spurious extra-cerebral artifacts, which should be rejected or cleaned up by the practitioner. Since manual screening of human EEGs is inherently error prone and might induce experimental bias, automatic artifact detection is an issue of importance. Automatic artifact detection is the best guarantee for objective and clean results. We present a new approach, based on the time–frequency shape of muscular artifacts, to achieve reliable and automatic scoring. The impact of muscular activity on the signal can be evaluated using this methodology by placing emphasis on the analysis of EEG activity. The method is used to discriminate evoked potentials from several types of recorded muscular artifacts—with a sensitivity of 98.8% and a specificity of 92.2%. Automatic cleaning ofEEGdata are then successfully realized using this method, combined with independent component analysis. The outcome of the automatic cleaning is then compared with the Slepian multitaper spectrum based technique introduced by Delorme et al (2007 Neuroimage 34 1443–9).
