Anthropogenic noise affects vocal interactions

Animal communication plays a crucial role in many species, and it involves a sender producing a signal and a receiver responding to that signal. The shape of a signal is determined by selection pressures acting upon it. One factor that exerts selection on acoustic signals is the acoustic environment through which the signal is transmitted. Recent experimental studies clearly show that senders adjust their signals in response to increased levels of anthropogenic noise. However, to understand how noise affects the whole process of communication, it is vital to know how noise affects the receiver’s response during vocal interactions. Therefore, we experimentally manipulated ambient noise levels to expose male European robins (Erithacus rubecula) to two playback treatments consisting of the same song: one with noise and another one without noise. We found that males responding to a conspecific in a noise polluted environment increased minimum frequency and decreased song complexity and song duration. Thus, we show that the whole process of communication is affected by noise, not just the behaviour of the sender.

Political participation as public pedagogy : The Educational Situation in Young People´s Political Conversations in Social Media

In this article we argue that young people’s political participation in the social media can be considered ‘public pedagogy’. The argument builds on a previous empirical analysis of a Swedish net community called Black Heart. Theoretically, the article is based on a particular notion of public pedagogy, education and Hannah Arendt’s expressive agonism. The political participation that takes place in the net community builds up an educational situation that involves central characteristics: communication, community building, a strong content focus and content production, argumentation and rule following. These characteristics pave the way for young people’s public voicing, experiencing, preferences and political interests that guide their everyday political life and learning – a phenomenon that we understand as a form of public pedagogy. 

Situating preparedness education within public pedagogy

Both ‘disaster preparedness’ and ‘public pedagogy’ have been broadly defined and diversely utilised. Preparedness has been dealt within the disciplines such as civil engineering, sociology of disasters, public health and psychology, rather than education. Recently, inquiries into the learning and teaching of preparedness is increasing in the field of education, and some of them position preparedness education within the field of public pedagogy. However, conceptual discussion as to how and why the two fields are associated has been limited. The primary aim of this paper is to fill this gap by drawing on public pedagogy literature that conceptualises ‘publics’ and ‘pedagogies’. By doing so, the paper attempts to respond to Burdick et al’s call for Problematizing Public Pedagogy.

The Path between Pedagogy and Technology: Establishing a Theoretical Basis for the Development of Educational Game Environments

The power of computer game technology is currently being harnessed to produce “serious games”. These “games” are targeted at the education and training marketplace, and employ various key game-engine components such as the graphics and physics engines to produce realistic “digital-world” simulations of the real “physical world”. Many approaches are driven by the technology and often lack a consideration of a firm pedagogical underpinning. The authors believe that an analysis and deployment of both the technological and pedagogical dimensions should occur together, with the pedagogical dimension providing the lead. This chapter explores the relationship between these two dimensions, and explores how “pedagogy may inform the use of technology”, how various learning theories may be mapped onto the use of the affordances of computer game engines. Autonomous and collaborative learning approaches are discussed. The design of a serious game is broken down into spatial and temporal elements. The spatial dimension is related to the theories of knowledge structures, especially “concept maps”. The temporal dimension is related to “experiential learning”, especially the approach of Kolb. The multi-player aspect of serious games is related to theories of “collaborative learning” which is broken down into a discussion of “discourse” versus “dialogue”. Several general guiding principles are explored, such as the use of “metaphor” (including metaphors of space, embodiment, systems thinking, the internet and emergence). The topological design of a serious game is also highlighted. The discussion of pedagogy is related to various serious games we have recently produced and researched, and is presented in the hope of informing the “serious game community”.

Development of a Collaborative Platform for Art Education: From Pedagogy to Technology

We report on the development of a Java-based application devised to support collaborative learning of Art concepts and ideas over the Internet. Starting from an examination of the pedagogy of both Art education and collaborative learning we propose principles which are useful for the design and construction of a “lightweight” software application which supports interactive Art learning in groups. This application makes “dynamics” of an art work explicit, and supports group interaction with simple messaging and “chat” facilities. This application may be used to facilitate learning and teaching of Art, but also as a research tool to investigate the learning of Art and also the development and dynamics of collaborating groups. Evaluation of a pilot study of the use of our system with a group of 20 school children is presented.

Seeing disadvantage in schools: exploring student teachers’ perceptions of poverty and disadvantage using visual pedagogy

This paper describes exploratory research into the development of innovative visual pedagogies for investigating how pre-service student teachers articulate their views about the effects of poverty on educational attainment. Social class emerges as the strongest factor in poverty and educational disadvantage in the UK. The resulting issues are often awkward for students to discuss and conventional pedagogies may not have effective ‘reach’ here. Findings from this study showed that the visual methods deployed gave students pedagogically well structured spaces for the expression and exchange of a diversity of views about poverty and social class, engaging them in both heated discussions and prolonged ‘silences’. However, the pedagogies did not challenge the stereotypical deficit models of ‘the poor’ which some students expressed. Nevertheless, we argue that reconfigured versions of these visual pedagogies have considerable potential for innovative social justice work in teacher education.

An Interdisciplinary Approach to the Management of Vocal Cord Dysfunction in an Elite Female Swimmer: a Case Study

Acute pulmonary disorders are commonplace within the athletic population, with exercise induced bronchoconstriction (EIB), and vocal cord dysfunction (VCD) common diagnoses. VCD is a condition that causes the adduction of the vocal folds during inhalation, causing obstruction at the larynx and thereby a severely impaired sporting performance. VCD can be brought on by laryngeal irritants, emotional and psychological stress and asthma. The gold standard of treatment for VCD centres on an interdisciplinary approach from specialists that often include a respiratory consultant, speech and language therapist (SLT) and a psychologist. The present case study details the interdisciplinary approach to the treatment of an elite female swimmer with VCD with an intervention programme that lasted nine weeks, instigated by a local general practitioner (G.P.) who chose to engage a Sport Psychology Consultant (SPC) due to the sport-specific nature of the psychological stress experienced by the individual. The steps involved in the design of the sport psychology interventions are outlined and the relationship of those interventions to the work of the other specialists is discussed. The 9 week intervention programme was aimed at reducing perfectionist tendencies and competitive state anxiety using a combination of cognitive behavioural therapy (CBT), goal-setting and imagery. Overall, the treatment programme was deemed a success as perfectionism and competitive state anxiety levels reduced over time along with the frequency of VCD occurrence. This case study demonstrates the breadth of roles that can be undertaken by a SPC and raises awareness of a complex respiratory disorder that is not yet fully understood.

Monsters Take to the Streets! Monstrous Street-Art as Pedagogy of Resistance to Post-Olympic Regeneration in Hackney Wick?

This chapter explores geographies of gentrification and resistance in relation to the monstrous through the lens of street-art in post-Olympic London. It takes as a geographic case study Hackney Wick, which has for a long time been a bastion of alternative and creative living due to cheap rents in large, ex-industrial warehouse spaces. The artistic sociality of the area is imbued within its landscape, as prolific street artists have adorned ex-industrial warehouses and canal-side walls with graffiti and murals. Since the announcement of the 2012 Olympic Games, the area has been a site of intense political and aesthetic contestation. The post-Olympic legacy means that the area has been earmarked for redevelopment, with current residents facing the possibility of joining thousands already displaced by the games. The anxiety of dispossession is reflected by monstrous characters and sinister disembodied teeth, eyes and fingers embedded within the landscape, painted by local artists. Using geographically sensitive mobile and visual methodology to document the landscape and artwork, the chapter analyses and interprets the monstrous themes using a range of theorists including Mikhail Bakhtin, Georges Bataille and Nick Land. I argue that monstrous street-art lays visible claim to public territory for aesthetic purposes at odds with the visions of redevelopers and the needs of capital. Whilst street-art and graffiti do not fit easily within frameworks of organized political resistance or collective social movements, they operate as a kind of epistemological transgression that triggers transformative affects in the viewer. This creates conditions for pedagogies of resistance to gentrification by expressing and mobilizing political affects such as anger and anxiety, raising awareness of geographical politics, and encouraging the viewer to question the status quo of the built environment.

Critical Pedagogy: Origin, Vision, Action & Consequences

Critical pedagogy is a transformation-based approach to education. The aim of this article is to introduce the origin, vision, action and consequences of critical pedagogy. It also aims on finding out about educators’ possibility of actualising it in their practice. As a source materials articles, book chapters and books are used. The literature shows that critical pedagogy has its origin in the tradition of critical theory of the Frankfurt School and the work of the Brazilian pedagog Paulo Freire. According to the literature, its major theses is that education should go beyond transfer of knowledge and training the future labour force; to help developing critical consciousness, which leads to transformation of the individual, learning environment and society at large. Critical pedagogy is criticised for a focus on macro level system, for not having a model for classroom implementation and for being abstract. Despite some critics, I argue that critical pedagogy has still the potential to empower those in the field of education to increase their consciousness about the injustice in their society and to involve in transforming it.   Keywords: Critical pedagogy, critical thinking, critical theory, dialogue, Frankfurt School, transformation.

Validade e fiabilidade do protocolo de avaliação da qualidade vocal da Universidade de Aveiro

O presente estudo teve como principal objetivo rever a versão original do Protocolo de Avaliação da Qualidade Vocal da Universidade de Aveiro (PAQVUA), criar o respetivo manual, comprovar a validade de conteúdo do PAQVUA assim como a sua fiabilidade inter e intra avaliador. Para rever a versão original do PAQVUA, foi efetuada uma revisão narrativa da literatura, com o objetivo de encontrar informação que revelasse a pertinência, da versão original do protocolo, para assim se efetuarem as alterações necessárias. Para analisar a validade de conteúdo recorreu-se a um painel de peritos, num total de seis, especialistas na área da voz que avaliaram as provas do PAQVUA, folha de registo e manual. Os peritos avaliaram todos os componentes do PAQVUA através do preenchimento de um questionário com o objetivo de se comprovar a relevância, clareza e precisão de cada uma das provas de avaliação e também o conteúdo do seu manual. Para além disso pretendeu-se também comprovar a fiabilidade inter e intra avaliador do PAQVUA. Para isso, o mesmo protocolo foi aplicado duas vezes por duas avaliadoras diferentes e também foi aplicado em dois momentos temporais diferentes por uma só avaliadora. A amostra teve um total de doze participantes. Para analisar estatisticamente os resultados da validade de conteúdo utilizou-se o método gráfico Bland e Altman modificado e o Coeficiente de Correlação Intraclasses (CCI). Para a fiabilidade inter e intra avaliador recorreu-se ao Coeficiente de Correlação de Spearman (ρ) e ao Kappa de Cohen (k). Relativamente aos resultados obtidos com o método Bland e Altman modificado, verificou-se a existência de concordância entre os peritos através da análise dos gráficos, sendo que a maioria dos pontos se encontrou dentro dos limites esperados de concordância. Quanto aos valores do CCI (entre 0.379 e 0.479), estes revelaram uma correlação regular. No que concerne à fiabilidade inter avaliador, os resultados de correlação e concordância apresentaram-se relevantes, com valores de ρ (de Spearman) superiores a 0.700 e valores de k (de Cohen) superiores a 0.600, na maioria dos casos. O mesmo foi constatado para a fiabilidade intra avaliador. Desta forma pode concluir-se que a nova versão do PAQVUA apresenta validade de conteúdo sendo tal comprovado pelo método de Bland-Altman modificado e pelos valores do CCI. Quanto à fiabilidade inter e intra avaliador, pode afirmar-se que o PAQVUA é fiável, porém como a amostra em estudo é pequena, o que a torna pouco representativa, esta conclusão carece de fundamento com base num estudo mais alargado. Apesar da limitação referida, acredita-se que este protocolo é uma mais-valia para o estudo da patologia vocal em ambiente clínico, assim como para a investigação científica nesta área, pois através do PAQVUA podem-se recolher diversas informações relacionadas com a voz, úteis para uma intervenção terapêutica baseada em evidências científicas.
