While the BBC had been broadcasting television Science Fiction productions from as early as 1938, and Horror since the start of television in 1936, American Telefantasy had no place on British television until ITV’s broadcast of Adventures of Superman (1952-1958) in 1956. It would be easy to assign this absence to the avoidance of popular American programming, but this would ignore the presence of Western and adventure serials imported from the US and Canada for monopoly British television. Similarly, it would be inaccurate to suggest that these imports were purely purchased as thrilling fare to appease a child audience, as it was the commercial ITV that was first to broadcast the more adult-orientated Science Fiction Theatre (1955-7) and Inner Sanctum (1954). This article builds on the work of Paul Rixon and Rob Leggott to argue that these imports were used primarily to supply relatively cheap broadcast material for the new channel, but that they also served to appeal to the notion of spectacular entertainment attached to the new channel through its own productions, such as The Invisible Man (1958-1959) and swashbucklers such as The Adventures of Robin Hood (1955-60). However, the appeal was not just to the exciting, but also to the transatlantic, with ITV embracing this conception of America as a modern place of adventure through its imports and its creation of productions for export, incorporating an American lead into The Invisible Man and drawing upon an (inexpensive) American talent pool of blacklisted screenwriters to provide a transatlantic style and relevance to its own adventure series. Where the BBC used its imported serials as filler directed at children, ITV embraced this transatlantic entertainment as part of its identity and differentiation from the BBC.

Many educational reforms have as one of their key goals the promotion of scientific literacy and they encourage engagement with science in the news as one aspect of this. The research indicates teachers using the news do so for a variety of reasons, sometimes with tangential links to the promotion of scientific literacy. Demonstrating the relevance of science to the world beyond the classroom or making links to socio-scientific issues and promoting discussion on ethical dilemmas are all seen as potential reasons for engaging with science–related news. However, media related issues are often not addressed. Increasingly the need for a more comprehensive approach, including, for example, teaching about media awareness in the context of science reporting, is highlighted. The steady growth of literature describing the use of science-related news along with research studies charting students’ responses to science news media has stimulated discussion and study of pedagogical issues and prompted this review. Key literature relevant to students’ engagement with science-related news reports has been contextualised and reviewed to identify core issues for teachers, teacher educators and curriculum planners. These are listed under the headings of curriculum, pedagogy and assessment, the implications are considered and directions for further research suggested.

The emergence of science parks is a relatively new phenomenon in China. Apart from the widely debated topics of university–industry linkages, collaboration among firms and spontaneous/policy-driven science parks, the development of science parks in China also has several distinguishing characteristics, such as their ambiguous linkage with urban expansion and their hierarchical structuring pattern. This paper attempts to discuss the motivation and efficiency of spatial proximity in science park development and to explore the role of universities in science parks, the function of science parks as a government project and a case study of location choice by on-site firms. The qualitative analysis, based on in-depth interviews with tenant firm managers and district-level government officers in Jiangning, Nanjing, is used as a basis for discussion.

This study sought to explore the current state of Grades 4 to 8 science education in Ontario from the perspective of Junior/Intermediate (J/I) teachers. The study’s methodology was a sequential 2-phased mixed methods explanatory design denoted as QUAN (qual) qual. Data were collected from an online survey and follow-up interviews. J/I teachers (N = 219) from 48 school boards in Ontario completed a survey that collected both quantitative and qualitative data. Interviewees were selected from the survey participant population (n = 6) to represent a range of teaching strategies, attitudes toward teaching science, and years of experience. Survey and interview questions inquired about teacher attitudes toward teaching science, academic and professional experiences, teaching strategies, support resources, and instructional time allotments. Quantitative data analyses involved the descriptive statistics and chi-square tests. Qualitative data was coded inductively and deductively. Academic background in science was found to significantly influence teachers’ reported level of capability to teach science. The undergraduate degrees held by J/I science teachers were found to significantly influence their reported levels of capability to teach science. Participants identified a lack of time allocated for science instruction and inadequate equipment and facilities as major limitations on science instruction. Science in schools was reported to be of a “second-tiered” value to language and mathematics. Implications of this study include improving undergraduate and preservice experiences of elementary teachers by supporting their science content knowledge and pedagogical content knowledge.

Aufgrund der breiten aktuellen Verwendung des Mythen-Begriffs in Kunst und Werbung, aber darüber hinaus auch in nahezu allen Bereichen gesellschaftlichen Lebens und vor allem in der Philosophie ergibt sich die Notwendigkeit, einen erweiterten Mythos-Begriff über das Historisch-Authentische hinaus zu verfolgen. Ausgehend von einer strukturalen Annäherung an den Mythos-Begriff im Sinne des von Roland Barthes vorgeschlagenen sekundären semiologischen Systems, d.h. einer semiologischen Sinnverschiebung zur Schaffung einer neuen – mythischen – Bedeutung, fordert diese neue Bedeutung eine Analyse, eine Mythenanalyse heraus. Dies ist deshalb so entscheidend, weil eben diese neue Bedeutung ihr mythisches Profil im Sinne von Hans Blumenberg durch forcierte Bedeutsamkeit für Individuen oder für bestimmte gesellschaftliche Gruppierungen unterlegt, z.B. durch bewusst intensive Wiederholung eines Themas oder durch unerwartete Koinzidenzen von Ereignissen oder durch Steigerung bzw. Depotenzierung von Fakten. Der erweiterte Mythen-Begriff verlangt nach einer Strukturierung und führt dabei zu unterschiedlichen Mythen-Ansätzen: zum Ursprungsstoff des authentischen Mythos und darauf basierender Geisteslage, zum Erkennen eines reflektierten Mythos, wenn es um das Verhältnis Mythos/Aufklärung geht, zum Zeitgeist-Mythos mit seinen umfangreichen Ausprägungen ideologischer, affirmativer und kritischer Art oder zu Alltagsmythen, die sich auf Persönlichkeitskulte und Sachverherrlichungen beziehen. Gerade der letztere Typus ist das Terrain der Werbung, die über den Gebrauchswert eines Produktes hinaus Wert steigernde Tauschwerte durch symbolische Zusatzattribute erarbeiten möchte. Hierbei können Markenmythen unterschiedlichster Prägung entstehen, denen wir täglich im Fernsehen oder im Supermarkt begegnen. Die Manifestation des Mythos in der Kunst ist einerseits eine unendliche Transformationsgeschichte mythischer Substanzen und andererseits ein überhöhender Bezug auf Zeitgeisterscheinungen, etwa bei dem Mythos des Künstlers selbst oder der durch ihn vorgenommenen „Verklärung des Gewöhnlichen“. Die Transformationsprozesse können u.a . prototypisch an zwei Beispielketten erläutert werden, die für den Kunst/Werbung-Komplex besonders interessant sind, weil ihr Charakter sich in einem Fall für die Werbung als äußerst Erfolg versprechend erwiesen hat und weil sich im zweiten Fall geradezu das Gegenteil abzeichnet: Zum einen ist es die Mythengestalt der Nymphe, jene jugendliche, erotisch-verführerische Frauengestalt, die über ihre antiken Wurzeln als Sinnbild der Lebensfreude und Fruchtbarkeit hinaus in und nach der Renaissance ihre Eignung als Verbildlichung der Wiederzulassung des Weiblichen in der Kunst beweist und schließlich der Instrumen-talisierung der Werbung dient. Im anderen Fall ist es die Geschichte der Medusa, die man idealtypisch als die andere Seite der Nympha bezeichnen kann. Hier hat Kunst Auf-klärungsarbeit geleistet, vor allem durch die Verschiebung des medusischen Schreckens von ihr weg zu einer allgemein-medusischen Realität, deren neue Träger nicht nur den Schrecken, sondern zugleich ihre Beteiligung an der Schaffung dieses Schreckens auf sich nehmen. Mythosanalyse ist erforderlich, um die Stellungnahmen der Künstler über alle Epochen hinweg und dabei vor allem diese Transformationsprozesse zu erkennen und im Sinne von Ent- oder Remythologisierung einzuordnen. Die hierarchische Zuordnung der dabei erkannten Bedeutungen kann zu einem Grundbestandteil einer praktischen Philosophie werden, wenn sie einen Diskurs durchläuft, der sich an Jürgen Habermas’ Aspekt der Richtigkeit für kommunikatives Handeln unter dem Gesichtspunkt der Toleranz orientiert. Dabei ist nicht nur zu beachten, dass eine verstärkte Mythenbildung in der Kunst zu einem erweiterten Mythen-begriff und damit zu dem erweiterten, heute dominierenden Kunstbegriff postmoderner Prägung geführt hat, sondern dass innerhalb des aktuellen Mythenpakets sich die Darstellungen von Zeitgeist- und Alltagsmythen zu Lasten des authentischen und des reflektierten Mythos entwickelt haben, wobei zusätzlich werbliche Markenmythen ihre Entstehung auf Verfahrensvorbildern der Kunst basieren. Die ökonomische Rationalität der aktuellen Gesellschaft hat die Mythenbildung keines-wegs abgebaut, sie hat sie im Gegenteil gefördert. Der neuerliche Mythenbedarf wurde stimuliert durch die Sinnentleerung der zweckrationalisierten Welt, die Ersatzbedarf anmeldete. Ihre Ordnungsprinzipien durchdringen nicht nur ihre Paradedisziplin, die Ökonomie, sondern Politik und Staat, Wissenschaft und Kunst. Das Umschlagen der Aufklärung wird nur zu vermeiden sein, wenn wir uns Schritt für Schritt durch Mythenanalyse unserer Unmündigkeit entledigen.

This essay aims to understand and interrogate the use of Colour Separation Overlay (CSO) as a mode of experimental production and aesthetic innovation in television drama in the 1970s. It sets out to do this by describing, accounting for and evaluating CSO as a production technique, considering the role of key production personnel, and analysing four specific BBC productions. Deploying methodologies of archival research, practitioner interview, and close textual analysis, the essay also delivers a significant reassessment of the role of the producer and designer in the conceptualisation and realisation of small-screen dramatic fiction.

This article responds to scholarship on Beckett’s television plays that regards them as positive interventions which encourage the viewer to reconsider the conventions of the medium, and that raise the cultural standards of television drama. In making claims about how the plays address and educate their viewers, critical approaches shift between conceptions of audience. This analysis of Beckett’s plays on British television reconsiders their aesthetic strategies, their relationship with television culture, and the dominant assumptions of critical writing about them by examining the parallel between conceptions of the audience and conceptions of the child in writing about television and Beckett’s television plays.

The inclusion of the history of science in science curricula-and specially, in the curricula of science teachers-is a trend that has been followed in several countries. The reasons advanced for the study of the history of science are manifold. This paper presents a case study in the history of chemistry, on the early developments of John Dalton`s atomic theory. Based on the case study, several questions that are worth discussing in educational contexts are pointed out. It is argued that the kind of history of science that was made in the first decades of the twentieth century (encyclopaedic, continuist, essentially anachronistic) is not appropriate for the development of the competences that are expected from the students of sciences in the present. Science teaching for current days will benefit from the approach that may be termed the ""new historiography of science"".

Over the last 50 years a new research area, science education research, has arisen and undergone singular development worldwide. In the specific case of Brazil, research in science education first appeared systematically 40 years ago, as a consequence of an overall renovation in the field of science education. This evolution was also related to the political events taking place in the country. We will use the theoretical work of Rene Kaes on the development of groups and institutions as a basis for our discussion of the most important aspects that have helped the area of science education research develop into an institution and kept it operating as such. The growth of this area of research can be divided into three phases: The first was related to its beginning and early configurations; the second consisted of a process of consolidation of this institution; and the third consists of more recent developments, characterised by a multiplicity of research lines and corresponding challenges to be faced. In particular, we will analyse the special contributions to this study gleaned from the field known as the history and philosophy of science.

We report here part of a research project developed by the Science Education Research Group, titled: "Teachers’ Pedagogical Practices and formative processes in Science and Mathematics Education" which main goal is the development of coordinated research that can generate a set of subsidies for a reflection on the processes of teacher training in Sciences and Mathematics Education. One of the objectives was to develop continuing education activities with Physics teachers, using the History and Philosophy of Science as conductors of the discussions and focus of teaching experiences carried out by them in the classroom. From data collected through a survey among local Science, Physics, Chemistry, Biology and Mathematics teachers in Bauru, a São Paulo State city, we developed a continuing education proposal titled “The History and Philosophy of Science in the Physics teachers’ pedagogical practice”, lasting 40 hours of lessons. We followed the performance of five teachers who participated in activities during the 2008 first semester and were teaching Physics at High School level. They designed proposals for short courses, taking into consideration aspects of History and Philosophy of Science and students’ alternative conceptions. Short courses were applied in real classrooms situations and accompanied by reflection meetings. This is a qualitative research, and treatment of data collected was based on content analysis, according to Bardin [1].

The history of the quinine synthesis can be used as a case study to emphasize that science is influenced by social and historical processes. The first efforts toward the synthesis of this substance, which until recently was the only treatment for malaria, were by Perkin in 1856 when, trying to obtain quinine,,. he synthesized mauveine. Since then, the quest for the total synthesis of quinine involved several characters in a web of controversies. A major step in this process was made in 1918 by Rabe and Kindler, who proposed the synthesis of quinine from quinotoxine. Twenty-six years later, after obtaining the total synthesis of quinotoxine, Woodward and Doering announced the total synthesis of quinine. However, the lack of experimental details about Rabe and Kindler's process, associated with Woodward and Doering's failure to reproduce it, raised a series of doubts about the synthesis. Stork and colleagues questioned the veracity of the experimental data and even the scientific reputation of the involved researchers. Doubts remained alive until 2008, when Williams and Smith reported, not without reservations, the reproducibility of Rabe and Kindler's protocol. The scientific knowledge as a social and historical development, its legitimating process, and the absence of neutrality in science constitute aspects that can be discussed from this case study, providing significant contributions to science education, in particular, to the initial or continued training of chemistry teachers.

This dissertation has two main purposes. On the one hand, it aims at comparing the gender stereotypes presented in the television commercials in China and in Europe. Considering the cultural, historical and socio-economical differences between these two contexts, it is interesting to examine the gender role models offered and used by the advertising industry in European Union and China in order to see if the gender stereotypes are similar and to evaluate to which extent they reflect, challenge or reinforce the gender roles of the society where they are broadcasted. On the other hand, the objective of this dissertation is to establish the degree of adequateness and effectiveness of the existing regulatory framework through an analysis of the positive and negative aspects of the regulatory acts issued to safeguard a fair representation of genders in the EU Member States and in China.

Assessing and managing risks relating to the consumption of food stuffs for humans and to the environment has been one of the most complex legal issues in WTO law, ever since the Agreement on Sanitary and Phytosanitary Measures was adopted at the end of the Uruguay Round and entered into force in 1995. The problem was expounded in a number of cases. Panels and the Appellate Body adopted different philosophies in interpreting the agreement and the basic concept of risk assessment as defined in Annex A para. 4 of the Agreement. Risk assessment entails fundamental question on law and science. Different interpretations reflect different underlying perceptions of science and its relationship to the law. The present thesis supported by the Swiss National Research Foundation undertakes an in-depth analysis of these underlying perceptions. The author expounds the essence and differences of positivism and relativism in philosophy and natural sciences. He clarifies the relationship of fundamental concepts such as risk, hazards and probability. This investigation is a remarkable effort on the part of lawyer keen to learn more about the fundamentals based upon which the law – often unconsciously – is operated by the legal profession and the trade community. Based upon these insights, he turns to a critical assessment of jurisprudence both of panels and the Appellate Body. Extensively referring and discussing the literature, he deconstructs findings and decisions in light of implied and assumed underlying philosophies and perceptions as to the relationship of law and science, in particular in the field of food standards. Finding that both positivism and relativism does not provide adequate answers, the author turns critical rationalism and applies the methodologies of falsification developed by Karl R. Popper. Critical rationalism allows combining discourse in science and law and helps preparing the ground for a new approach to risk assessment and risk management. Linking the problem to the doctrine of multilevel governance the author develops a theory allocating risk assessment to international for a while leaving the matter of risk management to national and democratically accountable government. While the author throughout the thesis questions the possibility of separating risk assessment and risk management, the thesis offers new avenues which may assist in structuring a complex and difficult problem

The educational platform Virtual Science Hub (ViSH) has been developed as part of the GLOBAL excursion European project. ViSH (http://vishub.org/) is a portal where teachers and scientist interact to create virtual excursions to science infrastructures. The main motivation behind the project was to connect teachers - and in consequence their students - to scientific institutions and their wide amount of infrastructures and resources they are working with. Thus the idea of a hub was born that would allow the two worlds of scientists and teachers to connect and to innovate science teaching. The core of the ViSH?s concept design is based on virtual excursions, which allow for a number of pedagogical models to be applied. According to our internal definition a virtual excursion is a tour through some digital context by teachers and pupils on a given topic that is attractive and has an educational purpose. Inquiry-based learning, project-based and problem-based learning are the most prominent approaches that a virtual excursion may serve. The domain specific resources and scientific infrastructures currently available on the ViSH are focusing on life sciences, nano-technology, biotechnology, grid and volunteer computing. The virtual excursion approach allows an easy combination of these resources into interdisciplinary teaching scenarios. In addition, social networking features support the users in collaborating and communicating in relation to these excursions and thus create a community of interest for innovative science teaching. The design and development phases were performed following a participatory design approach. An important aspect in this process was to create design partnerships amongst all actors involved, researchers, developers, infrastructure providers, teachers, social scientists, and pedagogical experts early in the project. A joint sense of ownership was created and important changes during the conceptual phase were implemented in the ViSH due to early user feedback. Technology-wise the ViSH is based on the latest web technologies in order to make it cross-platform compatible so that it works on several operative systems such as Windows, Mac or Linux and multi-device accessible, such as desktop, tablet and mobile devices. The platform has been developed in HTML5, the latest standard for web development, assuring that it can run on any modern browser. In addition to social networking features a core element on the ViSH is the virtual excursions editor. It is a web tool that allows teachers and scientists to create rich mash-ups of learning resources provided by the e-Infrastructures (i.e. remote laboratories and live webcams). These rich mash-ups can be presented in either slides or flashcards format. Taking advantage of the web architecture supported, additional powerful components have been integrated like a recommendation engine to provide personalized suggestions about educational content or interesting users and a videoconference tool to enhance real-time collaboration like MashMeTV (http://www.mashme.tv/).
