How to map the diversity of the audiovisual industry in the digital era. A Methodological Proposition

This article presents a methodological proposition to map the diversity of the audiovisual industry in the digital scenario by portraying the most important interactions between those who create, produce, distribute and disseminate audiovisual productions on line, paying special attention to powerful intermediaries and to small and medium independent agents. Taking as a point of departure a flexible understanding of social network analysis, the aim is to understand the structure of the audiovisual industry on the internet so that, taking into consideration a given sector, agents, their relations and the networks they give place to – as well as the structural conditions under which they operate – are studied. The aim is to answer questions such as: what is mapping, what is of interesting to map, how can it be done and what advantages and disadvantages the results will present.

Cooperative or collaborative learning: Is there a difference in university students’ perceptions?

The hypothesis that the same educational objective, raised as cooperative or collaborative learning in university teaching does not affect students’ perceptions of the learning model, leads this study. It analyses the reflections of two students groups of engineering that shared the same educational goals implemented through two different methodological active learning strategies: Simulation as cooperative learning strategy and Problem-based Learning as a collaborative one. The different number of participants per group (eighty-five and sixty-five, respectively) as well as the use of two active learning strategies, either collaborative or cooperative, did not show differences in the results from a qualitative perspective.

Concept maps as a tool to analyze the ideas of teacher training students regarding what to teach on human nutrition in Primary Education

Concept maps are a technique used to obtain a visual representation of a person's ideas about a concept or a set of related concepts. Specifically, in this paper, through a qualitative methodology, we analyze the concept maps proposed by 52 groups of teacher training students in order to find out the characteristics of the maps and the degree of adequacy of the contents with regard to the teaching of human nutrition in the 3rd cycle of primary education. The participants were enrolled in the Teacher Training Degree majoring in Primary Education, and the data collection was carried out through a training activity under the theme of what to teach about Science in Primary School? The results show that the maps are a useful tool for working in teacher education as they allow organizing, synthesizing, and communicating what students know. Moreover, through this work, it has been possible to see that future teachers have acceptable skills for representing the concepts/ideas in a concept map, although the level of adequacy of concepts/ideas about human nutrition and its relations is usually medium or low. These results are a wake-up call for teacher training, both initial and ongoing, because they shows the inability to change priorities as far as the selection of content is concerned.

Equipping young people to engage with media driven science experiences: beyond science knowledge to science literacy and discerning consumers of news.

This paper reports on a study of a curricular intervention for pupils (age 10-13 years) in the UK aimed at supporting critical engagement with science based media reports. In particular the study focused on core elements of knowledge, skills and attitudes identified in previous studies that characterize critical consumers of science presented as news. This was an empirical study based on classroom observation. Data included responses from individual pupils, in addition video recording of group activity and intentional conversations between pupils and teachers were scrutinised. Analysis focused on core tasks relating to different elements of critical reading. Pupils demonstrated a grasp of questioning and evaluating text, however the capacity to translate this experience in support of a critical response to a media report with a science component is limited in assessing the credibility of text and as an element in critical reading.

Improving Science literacy through interdisciplinary collaboration using media reported science.

The capability to respond critically to science in the news is recognised as one aspect of science literacy. Consequently, science-related news reports are an essential resource for science teachers wishing to promote critical reading as the foundation of a critical response to media reported science. Consequently Science education in schools should prepare students to engage with informal sources of science, including news media, in the world beyond formal science education. An interest in science news media is not limited to the science specialist. Science news provides an authentic context for teachers of science and English to collaborate in promoting interdisciplinary learning. The challenges of using science related news, as a context for cross-curricular collaboration, highlight the professional development needs of both science and English teachers working in this context. This qualitative study with over 150 pupils involved secondary school science and English teachers working collaboratively using media reported science resources and collated data from interviews, pre and post intervention tasks, pupils’ classwork and teacher notes. The outcomes of the project showed pupil engagement and greater capacity to carry knowledge and skills across traditional subject boundaries. Teachers reported increased understanding of the pedagogy of the alternative subject specialist and increased confidence to move outside their subject in order to facilitate pupil learning. This study would suggest that adopting an interdisciplinary approach could enhance learning for pupils and increase the confidence and capability of teachers. Additionally teachers’ engagement in professional conversations focusing on pupil progress was noteworthy.

Committing Curricular Time to Science Literacy: The Benefits from Science-based Media Resources

Science reported in the media is an authentic source material to explore science research and innovation, to learn how science works and to consolidate science literacy skills.

Media reports intended to communicate science research and innovation provide opportunities for teachers to develop among their pupils the critical reading skills that are essential for promoting literacy in science.

This study focuses on a curricular intervention with upper primary pupils (age 11 years) and uses science reported in the media to facilitate science directed learning in the primary curriculum.

The study suggests that the use of science based media reports can be a positive learning experience for pupils. Strategies and teaching approaches can be used to boost pupils’ confidence and competence to adopt critical reading strategies when they encounter science-based media.

Critical reading and reasoning strategies vary in their degree of difficulty. This study would suggest that, when using media-based resources, teachers need approaches that systematically address the different levels of cognative challenge presented by media resources and create opportunities within the curriculum to revisit, consolidate and develop pupils’ critical reasoning skills.

Development of N N SMRT for N a power of 2 and its Applications in Image Enhancement

Digital Image Processing is a rapidly evolving eld with growing applications in Science and Engineering. It involves changing the nature of an image in order to either improve its pictorial information for human interpretation or render it more suitable for autonomous machine perception. One of the major areas of image processing for human vision applications is image enhancement. The principal goal of image enhancement is to improve visual quality of an image, typically by taking advantage of the response of human visual system. Image enhancement methods are carried out usually in the pixel domain. Transform domain methods can often provide another way to interpret and understand image contents. A suitable transform, thus selected, should have less computational complexity. Sequency ordered arrangement of unique MRT (Mapped Real Transform) coe cients can give rise to an integer-to-integer transform, named Sequency based unique MRT (SMRT), suitable for image processing applications. The development of the SMRT from UMRT (Unique MRT), forward & inverse SMRT algorithms and the basis functions are introduced. A few properties of the SMRT are explored and its scope in lossless text compression is presented.

Through Class Darkly: Class in the British TV Noir

Class has always been at the heart of the television crime drama. Whether it is the post-war paternalism of Dixon of Dock Green (1955 – 1976), the harsh social realism of The Sweeney (1975-1978), or the almost mythical evocations of Britain in Heartbeat (1992 – 2010) and Midsomer Murders (1997- present), class and crime have always been seen as being inextricably linked. Since the 1990s, the British crime drama has been influenced by successive waves of cultural imports from, firstly, the US and then from Scandinavia. There is now a recognisable ‘genre’ for what we might think of as British TV Noir. Beginning with shows such as Cracker (1993 – 2006), Prime Suspect (1991 – 2006) and Messiah (2001) and continuing with dramas like Red Riding (2008), Southcliffe (2013) and Hinterland (2013 – present), the British TV Noir employs narratives and stylistic tropes that might usually be associated with the cinema of the 1940s. Although drawing influence from high profile shows such as Twin Peaks (1990 – 1991), Millennium (1996) and (latterly) The Wire (2002 – 2008), CSI (2000 – present) and The Killing (2007) these British Noir shows also articulate the nation’s shifting class system. As Susan Sydney-Smith has ably demonstrated, the crime drama is “historically contingent” (Sydney-Smith, 2002, p. 5) and shaped by the surrounding socio-political, as well aesthetic, context. To this end, this chapter traces the depiction of class in three key crime series – Prime Suspect, Red Riding and Southcliffe - and explores how social class, and more importantly, its changing face provides a constant background to the narratives and characterisations. These three texts were each produced at pivotal moments in Britain’s relationship to class – Prime Suspect was shown 6 months after Margaret Thatcher vacated office; Red Riding was produced in the midst of the global recession in 2008 and Southcliffe was made in the shadows of stringing welfare and immigration reforms. These texts span three successive political administrations and over two decades of social and political change. Understanding the relationship between criminal activity and class in these dramas however is far more complicated than simply reading the historical context through the text. Commensurate with its cinematic incarnation, TV Noir is both reflective and productive, employing visual and narrative tropes to manipulate, as well reflect, its audience’s moral and social positioning. The picture that emerges from an examination of class and the British TV Noir is one of suspicion and discontent. As Andrew Spicer suggests (with reference to British cinema) the Noir sensibility both depicts and critiques a society that it sees as being “class-ridden, racist and misogynist” (Spicer, 2002, p.202). This is certainly the case with the texts that are being examined here, as social positions and taxonomies are constantly being redefined and renegotiated.

Spatial and Temporal Variations in Airborne Ambrosia Pollen in Europe

Aim: The European Commission Cooperation in Science and Technology (COST) Action FA1203 “SMARTER” aims to make recommendations for the sustainable management of Ambrosia across Europe and for monitoring its efficiency and cost effectiveness. The goal of the present study is to provide a baseline for spatial and temporal variations in airborne Ambrosia pollen in Europe that can be used for the management and evaluation of this noxious plant . Location: The full range of Ambrosia artemisiifolia L. distribution over Europe (39oN-60oN; 2oW-45oE). Methods: Airborne Ambrosia pollen data for the principal flowering period of Ambrosia (August-September) recorded during a 10-year period (2004-2013) were obtained from 242 monitoring sites. The mean sum of daily average airborne Ambrosia pollen and the number of days that Ambrosia pollen was recorded in the air were analysed. The mean and Standard Deviation (SD) were calculated regardless of the number of years included in the study period, while trends are based on those time series with 8 or more years of data. Trends were considered significant at p < 0.05. Results: There were few significant trends in the magnitude and frequency of atmospheric Ambrosia pollen (only 8% for the mean sum of daily average Ambrosia pollen concentrations and 14% for the mean number of days Ambrosia pollen was recorded in the air). Main conclusions: The direction of any trends varied locally and reflect changes in sources of the pollen, either in size or in distance from the monitoring station. Pollen monitoring is important for providing an early warning of the expansion of this invasive and noxious plant.

Student attitudes towards cooperative learning in education

Abstract: Active or participatory learning by the student within a classroom environment has been fairly recently recognized as an effective, efficient, and superior instructional technique yet few teachers in higher education have adopted this pedagogical strategy. This is especially true in Science where teachers primarily lecture to passively seated students while using static visual aids or multimedia projections. Teachers generally teach as they were taught and lecture formats have been the norm. Although student-learning theories as well as student learning styles, abilities, and understanding strategies have changed, traditional teaching techniques have not evolved past the “chalk and talk” instructional strategy. This research looked into student’s perceptions of cooperative learning or team-based active learning in order to gain insight and some understanding as to how students felt about this learning technique. Student’s attitudes were then compared to student grades to detennine whether cooperative learning impeded or ameliorated academic performance. The results revealed significant differences measured in all the survey questions pertaining to perception or attitudes. As a result of the cooperative learning activities, respondents indicated more agreement to the survey questions pertaining to the benefits of cooperative learning. The experimental group exposed to cooperative learning thus experienced more positive attitudes and perceptions than the groups exposed only to a lecture-based teaching and learning format. Each of the hypotheses tested demonstrated that students had more positive attitudes towards cooperative learning strategies. Recommendations as to future work were presented in order to gain a greater understanding into both student and teacher attitudes towards the cooperative learning model.||Résumé: Lapprentissage actif ou préparatoire par létudiant au sein d’une classe a été reconnu assez récemment comme une technique d’enseignement plus efficace. Cependant, peu d’enseignants ont adopté cette stratégie pedagogique pour l'éducation post-secondaire. Ceci est particulièrement le cas dans le domaine des sciences où les enseignants font surtout usage de cours magistraux avec des étudiants passifs tout en utilisant des aides visuelles statiques ou des projections multimédias. Les professeurs enseignent generalement comme on leur a eux-même enseigné et les cours magistraux ont été la norme par le passé. Les techniques traditionnelles d'enseignernent n'ont pas évolué au-delà de la craie et du tableau noir et ce même si les théories sur l’apprentissage par les étudiants ont changé, tout comme les styles, les habiletés et les stratégies de compréhension d’apprentissage des étudiants. Cette recherche se penche sur les perceptions des étudiants au sujet de l'apprentissage coopératif ou de l'apprentissage actif par équipe de telle sorte qu'on puisse avoir un aperçu et une certaine compréhension de comment les étudiants se sentent par rapport à ces techniques d'apprentissage. Les attitudes des étudiants ont par la suite été comparées aux notes de ceux-ci pour déterminer si l'apprentissage coopératif avait nui ou au contraire amélioré leurs performances académiques. Les résultats obtenus dans l'étude d'ensemble révèlent des différences significatives dans toutes les questions ayant trait à la perception et aux attitudes.

Sexting na adolescência: análise da rede de enunciações produzida pela mídia

Esta tese foi produzida no Programa de Pós -Graduação em Educação em Ciências : Química da Vida e Saúde , na linha de pesquisa "Educação científica : implicações das práticas científicas na constituição dos sujeitos ". O objetivo desta pesquisa é analisar a rede de enunciações sobre o sexting em alguns materiais (reportagens, programas televisivos, postagens em blogs e comentários realizados por leitores dos sites) presentes na internet e investigar as condições de emergência da prática do sexting. O sexting é um termo criado nos Estados Unidos da América, que deriva das expressões sex (sexo) e texting (envio de mensagens). Esse conceito descreve uma prática social e cultural que está sendo difundida mundialmente: esta consiste em produzir e enviar fotos e vídeos sexuais, sensuais e eróticos entre conhecidos/as, amigos/as, namorados/as, “ficantes” etc.. Nesta pesquisa, utilizamos como aporte teórico os estudos de Pierre Lévy, André Lemos, Paula Sibilia, Guy Debord, Hannah Arendt, Michel Foucault e Zygmunt Bauman. Tais autores ajudam-nos a pensar que o sexting emerge devido a alguns acontecimentos sociais, culturais, históricos etc., que vêm provocando alguns deslocamentos em nossa sociedade. Para proceder com tal pesquisa, utilizamos a internet como campo empírico. Em nossa busca, encontramos 48 artefatos culturais que discutem, de alguma forma, sobre sexting. Dentre estes, 37 comentam sobre vídeos caseiros que mostram relações sexuais, 8 discutem sobre o fenômeno sexting e 3 debatem sobre a produção de fotos sensuais. Para análise dos dados, utilizamos algumas ferramentas foucaultianas, especialmente os conceitos de discurso, dispositivo e enunciado. Ao olharmos os materiais, percebemos que os/os adolescentes vêm se utilizando das tecnologias digitais para visibilizarem a sua sexualidade, o que nos dá indícios de que estas vêm possibilitando a constituição de jornalistas cidadãos/ãs. Além disso, evidenciamos que as fotos e vídeos dos/as adolescentes foram produzidos em comum acordo entre eles/as. Muitos dessas fotos e vídeos, foram disseminados pelos próprios sujeitos que aderiram a essa prática. Assim, a exposição da sexualidade, por meio do sexting, tem sido realizada com o propósito de adquirir visibilidade e de tornar-se a personalidade do momento. Entendemos que essa vontade de escancarar a sexualidade, por meio das tecnologias digitais, está vinculada à sociedade do espetáculo, que manifesta a necessidade de tornar-se visível. Além disso, notamos que essa prática está relacionada à escola, pois muitos dos casos relatados ocorreram no interior dessa instituição ou tiveram uma repercussão nesse ambiente. Em muitos casos, a escola era culpabilizada pelos casos de sexting que envolviam seus/sua alunos/as. No entanto, são os pais o foco de maiores críticas pela mídia massiva, pois, para essa instância, são estes os maiores responsáveis pela disciplinarização desses corpos. Evidenciou-se também que os/as praticantes do sexting sofreram micropenalidades, as quais tinham como objetivo corrigir suas condutas. Nesse sentido, entendemos o sexting como uma atualização do dispositivo da sexualidade, pois este coloca a sexualidade – a qual, durante a modernidade sólida, constituía-se como algo exclusivamente do âmbito privado – em evidência nos espaços públicos. Ao mesmo tempo, verificamos que algumas práticas disciplinares ainda buscam governar e normalizar a sexualidade dos sujeitos. A análise do material empírico possibilitou-nos verificar dois enunciados que fazem parte do discurso do sexting. O primeiro destes é que, na contemporaneidade, aparecer é uma condição de existência; o outro é que a sexualidade é entendida como algo que deve ser regulado, governado e normalizado. Consideramos importante centrarmos os estudos no sexting, pois entendemos que essa prática vem contribuindo para o surgimento de outros modos de viver e entender a sexualidade, pois o sexting enquadra a sexualidade como algo a ser exibido e mostrado para todos/as.

Rethinking the STEM fields: the importance of definitions in examining women's participation and success in the sciences

This study uses longitudinal data of undergraduate students from five public land-grant universities to better understand undergraduate students’ persistence in and switching of majors, with particular attention given to women’s participation in Science, Technology, Engineering, and Mathematics (STEM) fields. Specifically, the study examines patterns of behavior of women and minorities in relation to initial choice of college major and major field persistence, as well as what majors students switched to upon changing majors. Factors that impact major field persistence are also examined, as well as how switching majors affects students’ time-to-degree. Using a broad definition of STEM, data from nearly 17,000 undergraduate students was analyzed with descriptive statistics, cross tabulations, and binary logistic regressions. The results highlight women’s high levels of participation and success in the sciences, challenging common notions of underrepresentation in the STEM fields. The study calls for researchers to use a comprehensive definition of STEM and broad measurements of persistence when investigating students’ participation in the STEM fields.

Curriculum, content and controversy in higher education

Recent evidence suggest that academic staff face difficulties in applying new technologies as a means of assessing higher order assessment outcomes such as critical thinking, problem solving and creativity. Although higher education institutional mission statements and course unit outlines purport the value of these higher order skills there is still some question about how well academics are equipped to design curricula and, in particular, assessment strategies accordingly. Despite a rhetoric avowing the benefits of these higher order skills, it has been suggested that academics set assessment tasks up in such a way as to inadvertently lead students on the path towards lower order outcomes. This is a controversial claim, and one that this paper seeks to explore and critique in terms of challenging the conceptual basis of assessing higher order skills through new technologies. It is argued that the use of digital media in higher education is leading to a focus on student's ability to use and manipulate of these products as an index of their flexibility and adaptability to the demands of the knowledge economy. This focus mirrors market flexibility and encourages programmes and courses of study to be rhetorically packaged as such. Curricular content has becomes a means to procure more or less elaborate aggregates of attributes. Higher education is now charged with producing graduates who are entrepreneurial and creative in order to drive forward economic sustainability. It is argued that critical independent learning can take place through the democratisation afforded by cultural and knowledge digitization and that assessment needs to acknowledge the changing relations between audience and author, expert and amateur, creator and consumer.
