Do the “democratization” of media and the proliferation of online participatory culture undermine the aesthetic hegemony of professional filmmakers? This article is a case study of both more and less popular animated Lego videos, also called “brickfilms,” that asks how amateur videos adhere to and/or depart from professionalized aesthetic standards. It addresses the definitions of professionalism and amateurism and proposes that the dichotomy between democratization and ongoing elitism is insufficient to describe the complex dialogue between professional film aesthetics and amateur production—a dialogue that is diverse but nonetheless follows certain patterns. These patterns link Lego videos to silent era cinema as well as contemporary professional live-action and stop-motion animation. Furthermore, a mixture of parody, pastiche, and homage suggest that amateur work has a variety of affective relationships to professional work. Ultimately, amateur filmmaking indicates a negotiation of professional standards rather than slavish adherence.

The human cytochrome P450s constitute an important family of monooxygenase enzymes that carry out essential roles in the metabolism of endogenous compounds and foreign chemicals. We present here results of a fusion between a human P450 enzyme and a bacterial reductase that for the first time is shown does not require the addition of lipids or detergents to achieve wild-type-like activities. The fusion enzyme, P450 2E1-BMR, contains the N-terminally modified residues 22-493 of the human P450 2E1 fused at the C-terminus to residues 473-1049 of the P450 BM3 reductase (BMR). The P450 2E1-BMR enzyme is active, self-sufficient and presents the typical marker activities of the native human P450 2E1: the hydroxylation of p-nitrophenol (K (M)=1.84 +/- 0.09 mM and k (cat) of 2.98 +/- 0.04 nmol of p-nitrocatechol formed per minute per nanomole of P450) and chlorzoxazone (K (M)=0.65 +/- 0.08 mM and k (cat) of 0.95 +/- 0.10 nmol of 6-hydroxychlorzoxazone formed per minute per nanomole of P450). A 3D model of human P450 2E1 was generated to rationalise the functional data and to allow an analysis of the surface potentials. The distribution of charges on the model of P450 2E1 compared with that of the FMN domain of BMR provides the ground for the understanding of the interaction between the fused domains. The results point the way to successfully engineer a variety of catalytically self-sufficient human P450 enzymes for drug metabolism studies in solution.

Legislation: Regulation 6/2002 on Community designs art.3(3)(e) Directive 98/71 on the legal protection of designs art.7(1) Cases: Dyson Ltd v Vax Ltd [2010] EWHC 1923 (Pat); [2011] Bus. L.R. 232 (Ch D (Patents Ct)) Lego Juris A/S v Office for Harmonisation in the Internal Market (Trade Marks and Designs) (OHIM) (C-48/09 P) Unreported September 14, 2010 (ECJ) *E.I.P.R. 60 In Lego, the Court of Justice of the European Union denied registration for an exclusively functional shape mark despite the availability of other shapes capable of fulfilling the same function and in Dyson v Vax Mr Justice Arnold established that a design can not be registered for a purely functional shape even though another shape could fulfil the same required function.

Studien zufolge ist das Schulfach Physik eines der unbeliebtesten Schulfächer. Die Beweggründe für diese Einstellungen sind vielfältig: Kaum ein Schulfach verwendet eine so künstliche Sprache und begibt sich in eine derart abstrakte und nüchterne Gedanken- und Zahlenwelt. Um die Defizite des Physikunterrichts zu überwinden, gab es in den vergangenen Jahren immer wieder Versuche von Lehrmittelherstellern, aktuelle Forschungsergebnisse der Physik-Fachdidaktik in die Entwicklung von Lehrmitteln für den Physikunterricht einfließen zu lassen. Auch der dänische Spielzeughersteller Lego bietet seit 1998 mit seinem Lego Mindstorms System ein Lehrmittel an, das neben dem Einsatz im Informatik- und Mathematikunterricht auch Möglichkeiten zur Anwendung im Physikunterricht zulässt. Die aktuellste Version der Lego Mindstorms bietet zahlreiche Versuche zu verschiedenen Bereichen der Physik an. Lego Mindstorms Experimente ermöglichen so einen spielerischen und positiv belegten Zugang zu Physikexperimenten. Allerdings stellt sich die Frage, inwiefern die Lego Mindstorms Experimente geeignet sind, die eingangs benannten Defizite des Physikunterrichts zu verringern. Kann der Einsatz von Lego Mindstorms Physikexperimenten also dazu beitragen, Lernbarrieren und Hemmnisse abzubauen, das Selbstkonzept der Lernenden sowie deren Interesse am Physikunterricht zu verbessern und gleichzeitig einen kontextorientierten und fachwissenschaftlich fundierten Unterricht zu ermöglichen?

Este trabalho foi elaborado no âmbito do Mestrado de Ensino de Matemática do 3º Ciclo do Ensino Básico e Secundário da Universidade da Madeira, no ano letivo de 2012/2013. Os grandes objetivos deste estudo são os de analisar qualitativamente uma atividade, para compreender como é que os alunos aprendem trigonometria, utilizando os robots NXT da Lego. De igual modo, se procede também, de forma sucinta, à apresentação do trabalho desenvolvido pelo grupo de estágio, ao longo da Prática de Ensino Supervisionado. Para a realização da investigação, foram recolhidos dados pelo investigador, através de registos audiovisuais do trabalho dos alunos, com câmara e vídeo. Com o fim de melhor estudar o problema aqui apresentado, o mesmo foi dissecado em três questões de investigação: (a) Que aprendizagens os alunos realizam com a montagem, programação e interação com os robots? (b) De que forma é que os alunos aprendem trigonometria, quando utilizam os Robots? (c) Quais as dificuldades manifestadas pelos alunos na resolução de problemas? As questões de investigação iluminaram a análise dos dados. Das conclusões que advêm deste estudo destaca-se o papel essencial da robótica e dos materiais manipuláveis, na construção e concetualização do conhecimento dos alunos.
