El fre magnètic : experimentant amb els corrents de Foucault

En aquest treball pràctic es proposa el fenomen de la caiguda d'un imant de neodimi per un tub metàl·lic vertical (no ferromagnètic).També es proposa investigar com afecta el gruix del tub al temps de caiguda de l'imant; per a això fem servir un rotlle de paper d'alumini. Per mesurar el temps de caiguda podem fer servir sensors Hall i l'oscil·loscopi o bé un cronòmetre

Knowledge management in the voluntary sector: A focus on sharing project know-how and expertise

Voluntary sector organisations are operated principally by volunteers who are not obliged to share their knowledge, as might be expected in a for profit company, with a greater consequent loss of knowledge should individuals leave. This research examines how a volunteer-led organisation, the Campaign for Real Ale (CAMRA), acquires, stores and shares its project knowledge in the context of event management. Three annual CAMRA festivals of different sizes and maturity were selected to see how volunteers' knowledge is managed in the process of organising their festivals. Key festival officers were interviewed and focus groups, comprising of festival volunteers, were conducted. While the maturity of a festival and its size seemed to influence the ways in which knowledge was managed there were some commonalities between festivals. Evident was a strong master-apprentice model of learning with little formal training or record keeping except, that is, where legislation and accountability in treasury and health and safety functions were necessary. Trust between volunteers and their need to know and to share information appeared to be dependent, in part, on their perception and confidence in the success of the overarching project organisation, and this helped shape volunteers' knowledge sharing practices. Whilst there was evidence of a laissez-faire approach to codification and the sharing of knowledge, this was less so when volunteers recognised a genuine lack of knowledge which would hinder the success of their festival. The analysis also highlighted factors related to the sharing of knowledge that, it is suggested, have not been identified in the for-profit sector

Història, narrativitat i gir lingüístic. Algunes consideracions

En aquest article s'intenta discutir quines han estat les aportacions de la narrativitat i del gir lingüístic a la historiografia i a la teoria de la història, en el context de la crisi de les ciències socials en el darrer quart de segle, presidit a Occident per la globalització capitalista i per l'eclosió identitària.An attempt to discuss what have been the contributions of narrative and of linguistic turn to historiography and the theory of history in the context of the crisis within social science in the last quarter of a century, dominated in the West by capitalist globalisation and an emerging sense of identity

De la Solidaritat Catalana a la Setmana Tràgica : la premsa il·lustrada barcelonina

Durant el període 1905-1909, a cavall dels esdeveniments político-socials, es produeixen dos fenòmens essencials en la premsa il·lustrada catalana. El primer seria l'amplitud de la seva difusió i de la seva influència sobre els propis esdeveniments; el segon, el pas decisiu i massiu del dibuix gravat a la fotografia i, per a aquesta, la identificació de la seva autoria.Durante el período 1905-1909, a caballo de los acontecimientos político-sociales, se producen dos fenómenos esenciales en la prensa ilustrada catalana.

The Support Needed for Spouses of Traumatic Brain Injury (TBI) Survivors: An Exploration into Resources and Reference Materials

Traumatic brain injury (TBI) is, indeed, an equal opportunity perpetrator. Of the millions of Americans who sustain a TBI each year, at least 230,000 people are hospitalized and survive, and more than 80,000 to 90,000 people experience the onset of long-term disability (“Report to Congress”). However, it would appear that the reference materials and resources available to those needing life guidance post-TBI are not at all commensurate with the incidence of its occurrence. More specifically, it seems the population most overlooked within the world of those affected by TBI is the partners of adult TBI victims

El cinema (i altres mitjans audiovisuals) sobre el geneocidi armeni

Estudio del cine (y de otros medios audiovisuales) que ha tratado el tema del genocidio de los armenios perpetrado por el Imperio Otomano durante la primera guerra mundial (1914-1918). Se contemplan los films realizados en cualquier parte del mundo, pero se observa la gran importancia de la diáspora armenia en su producción. No fue hasta los años sesenta del siglo XX cuando esta cinematografía empezó a adquirir un grueso considerable, debido a la constante actuación de Turquía en contra de él. Se distingue entre los films documentales y los argumentales y de ensayo cinematográfico.
