The Glow of Unwork? Issues of Portrayal in Networked Learning Research

In this paper, we suggest that portrayal of research is often undervalued and seen as ‘unwork’ (Galloway, 2012). Portrayal is often seen as an issue that is relatively straight forward by qualitative researchers, and invariably refers to putting the findings of the study together with excerpts from participants and usually, but not always, some interpretation. It tends to be seen as the means by which the researcher has chosen to position people and their perspectives, and it is imbued with a sense of not only positioning but also a contextual painting of a person in a particular way. Yet there are an array of issues and challenges about what portrayal can or might mean in digital spaces. In this paper we argue that researching education in a digital age provides greater or different opportunities to represent and portray data differently and suggest that these ways are underutilised. For example, for many researchers legitimacy comes through the use of participants’ voices in the form of quotations. However, we argue that this stance towards plausibility and legitimacy is problematic and needs to be reconsidered in terms of understanding differences in types of portrayal, recognizing how researchers position themselves in relation to portrayal, and understanding decision-making in relation to portrayal. We suggest that there need to be new perspectives about portrayal and concept, and ideas are provided that offer a different view. Three key recommendations are made: Portrayal should be reconceptualised as four overlapping concepts: mustering, folding, cartography, and portrayal. Adopting such an approach will enable audiences, researchers and other stakeholders to critique the assumptions that researchers on tour bring to portrayal and encourage reflexivity. Researchers on tour should highlight the temporal, mutable and shifting nature of portrayed research findings, emphasising the need for continued and varied research to inform understanding. There is a significant need for greater insight into the influence of portrayal, as well as the difference between representation and portrayal. Future studies should prioritise this, and ensure that portrayal is considered and critiqued from the outset.

Developing Innovative TEL Practice in Teacher Education

This interactive symposium will focus on the use of different technologies in developing innovative practice in teacher education at one university in England. Technology Enhanced Learning (TEL) is a field of educational policy and practice that has the power to ignite diametrically opposing views and reactions amongst teachers and teacher educators, ranging across a spectrum from immense enthusiasm to untold terror. In a field where the skills and experience of individuals vary from those of digital natives (Prensky 2001) to lags and lurkers in digital spaces, the challenges of harnessing the potential of TEL are complex. The challenges include developing the IT skills of trainees and educators and the creative application of these skills to pedagogy in all areas of the curriculum. The symposium draws on examples from primary, secondary and post-compulsory teacher education to discuss issues and approaches to developing research capacity and innovative practice using different etools, many of which are freely available. The first paper offers theoretical and policy perspectives on finding spaces in busy professional lives to engage in research and develop research-informed practice. It draws on notions of teachers as researchers, practitioner research and evidenc-ebased practice to argue that engagement in research is integral to teacher education and an empowering source of creative professional learning for teachers and teacher educators. Whilst acknowledging the challenges of this stance, examples from our own research practice illustrate how e-tools can assist us in building the capacity and confidence of staff and students in researching and enhancing teaching, learning and assessment practice. The second paper discusses IT skills development through the TEL pathway for trainee teachers in secondary education across different curriculum subjects. The lead tutor for the TEL pathway will use examples of activities developed with trainee teachers and university subject tutors to enhance their skills in using e-tools, such as QR codes, Kahoot, Padlet, Pinterest and cloud based learning. The paper will also focus on how these skills and tools can be used for action Discussant - the wider use of technologies in a university centre for teacher education; course management, recruitment and mentor training. research, evaluation and feedback and for marking and administrative tasks. The discussion will finish with thoughts on widening trainee teachers’ horizons into the future direction of educational technology. The third paper considers institutional policies and strategies for promoting and embedding TEL, including an initiative called ‘The Learning Conversation’, which aims ‘to share, highlight, celebrate, discuss, problematise, find things out...’ about TEL through an online space. The lead for ‘The Learning Conversation’ will offer reflections on this and other initiatives across the institution involving trainee teachers, university subject tutors, librarians and staff in student support services who are using TEL to engage, enthuse and support students on campus and during placements in schools. The fourth paper reflects on the use of TEL to engage with trainee teachers in post-compulsory education. This sector of education and training is more fragmented than primary and secondary schools sectors and so the challenges of building a community of practice that can support the development of innovative practice are greater.

An examination of the role of sound in defining the city in the context of Edinburgh

The surfeit of generic and place-specific sounds that exist in the urban environment contribute to what has been referred to as the soundscape. Within the built environment sound has the potential to create thresholds and acoustic territories that define and colour the experience and social functioning of inhabited spaces. In this research, a robust critical examination of the literature by prominent sound artists and theorists is used to illustrate how sound contributes to the urban experience. This is reinforced by primary research undertaken in the city of Edinburgh where the analysis and synthesis of these secondary sources is tested using bespoke soundworks to determine the ways in which sound contributes to our perception, reading and understanding of our physical environment. This research concludes by illustrating the potential for the future, technological development of the soundscape.

Art-Map: concept of moving curatorial project and its practical realization in Aveiro

In this dissertation, I present the results of a project which aim was to find out and try an effective model of independent curatorial project executable in small and medium cities in Portugal. The concept of Moving Curatorial Project ARTMAP is a result of theoretical research and reflection about municipal exhibition spaces and possibility of presentation of the contemporary art in these spaces. To test if this curatorial project is realizable and if there are conditions to continue it, a first trial was implemented in Aveiro. A curated international exhibition, entitled “A Poética do Visual" occupied two municipal and two private gallery spaces and brought together 111 artists from 25 different countries. The art event was carried out in collaboration with the Municipality of Aveiro and the University of Aveiro, and involved several private cultural spaces in the city. This first experience showed that there are all conditions for the presentation of contemporary art in small and medium size locations in Portugal, and for this project to be replicated in other regions of the country.

Learning to construct our identities over the life course: a study with lesbian, gay, bisexual and transgender adults in Scotland

To date, adult educational research has had a limited focus on lesbian, gay, bisexual and transgendered (LGBT) adults and the learning processes in which they engage across the life course. Adopting a biographical and life history methodology, this study aimed to critically explore the potentially distinctive nature and impact of how, when and where LGBT adults learn to construct their identities over their lives. In-depth, semi-structured interviews, dialogue and discussion with LGBT individuals and groups provided rich narratives that reflect shifting, diverse and multiple ways of identifying and living as LGBT. Participants engage in learning in unique ways that play a significant role in the construction and expression of such identities, that in turn influence how, when and where learning happens. Framed largely by complex heteronormative forces, learning can have a negative, distortive impact that deeply troubles any balanced, positive sense of being LGBT, leading to self- censoring, alienation and in some cases, hopelessness. However, learning is also more positively experiential, critically reflective, inventive and queer in nature. This can transform how participants understand their sexual identities and the lifewide spaces in which they learn, engendering agency and resilience. Intersectional perspectives reveal learning that participants struggle with, but can reconcile the disjuncture between evolving LGBT and other myriad identities as parents, Christians, teachers, nurses, academics, activists and retirees. The study’s main contributions lie in three areas. A focus on LGBT experience can contribute to the creation of new opportunities to develop intergenerational learning processes. The study also extends the possibilities for greater criticality in older adult education theory, research and practice, based on the continued, rich learning in which participants engage post-work and in later life. Combined with this, there is scope to further explore the nature of ‘life-deep learning’ for other societal groups, brought by combined religious, moral, ideological and social learning that guides action, beliefs, values, and expression of identity. The LGBT adults in this study demonstrate engagement in distinct forms of life-deep learning to navigate social and moral opprobrium. From this they gain hope, self-respect, empathy with others, and deeper self-knowledge.

The spectral albedo of sea ice and salt crusts on the tropical ocean of Snowball Earth: II. Optical modeling

During the Snowball Earth events of the Neoproterozoic, tropical regions of the ocean could have developed a precipitated salt lag deposit left behind by sublimating sea ice. The major salt would have been hydrohalite, NaCl•2H2O. The crystals in such a deposit can be small and highly scattering, resulting in an allwave albedo similar to that of snow. The snow-free sea ice from which such a crust could develop has a lower albedo, around 0.5, so the development of a crust would substantially increase the albedo of tropical regions on Snowball Earth. Hydrohalite crystals are much less absorptive than ice in the near- infrared part of the solar spectrum, so their presence at the surface would increase the overall albedo as well as altering its spectral distribution. In this paper, we use laboratory measurements of the spectral albedo of a hydrohalite lag deposit, in combination with a radiative transfer model, to infer the inherent optical properties of hydrohalite as functions of wavelength. Using this result, we model mixtures of hydrohalite and ice representing both artificially created surfaces in the laboratory and surfaces relevant to Snowball Earth. The model is tested against sequences of laboratory measurements taken during the formation and the dissolution of a lag deposit of hydrohalite. We present a parameterization for the broadband albedo of cold, sublimating sea ice as it forms and evolves a hydrohalite crust, for use in climate models of Snowball Earth.

Il progetto dello spazio pubblico al tempo del trust. Metodi e progetti in contesti urbani e periferici

Lo spazio pubblico urbano potrebbe essere visto come una scenografia mutevole in cui la società rappresenta sé stessa. Soprattutto nei centri storici della città, si perde l’identità di luoghi specifici, così come la coscienza dei cittadini, che porta ad un uso improprio dello spazio causato principalmente dall’assenza di una cultura architettonica. In questo senso, l’obiettivo finale dell’architettura è quello di essere educativa nello spiegare il motivo per cui è stata concepita. La tesi di ricerca tenta di studiare la dimensione educativa e la forza che l’architettura ha nell’influenzare comportamenti spontanei e non spontanei. L’obiettivo è trovare metodi di progettazione e legali in grado di migliorare gli spazi pubblici in termini di qualità della vita dei suoi utenti. Il riconoscimento e la trasmissione dell’architettura, attraverso l’uso dell’architettura stessa, tenta di arginare un’assenza di cultura architettonica e un uso sempre più improprio dei suoi spazi. La domanda a cui, dunque, si tenta di rispondere è: Può la dimensione evocativa dell’architettura stimolare processi di rigenerazione urbana? La tesi si sviluppa in tre parti: la prima presenta alcune riflessioni teoriche sulla progettazione dello spazio pubblico alle quali fanno riferimento altrettanti progetti portati avanti nei mesi di ricerca Dai workshops realizzati sono emerse diverse problematiche riguardo l’effettiva realizzazione di tali progetti evidenziando soprattutto una carenza di tipo normativo che fa “cadere” gli entusiasmi legati al completamento delle opere per la comunità e di conseguenza decade il valore teorico dei progetti. Per questo motivo, nella seconda parte, si tenta di approfondire il tema legislativo per trovare soluzioni alternative agli arresti burocratici che sovente disincentivano le azioni corali della cittadinanza. La terza parte si concentrerà su un progetto per un’area di Bologna da riqualificare, i Prati di Caprara, per i quali si sfrutteranno tutte le conoscenze teoriche precedentemente esposte.

Probing the innermost regions of AGN via time-resolved spectral analysis

The dynamics and geometry of the material inflowing and outflowing close to the supermassive black hole in active galactic nuclei are still uncertain. X-rays are the most suitable way to study the AGN innermost regions because of the Fe Kα emission line, a proxy of accretion, and Fe absorption lines produced by outflows. Winds are typically classified as Warm Absorbers (slow and mildly ionized) and Ultra Fast Outflows (fast and highly ionized). Transient Obscurers -optically thick winds that produce strong spectral hardening in X-rays, lasting from days to months- have been observed recently. Emission and absorption features vary on time-scales from hours to years, probing phenomena at different distances from the SMBH. In this work, we use time-resolved spectral analysis to investigate the accretion and ejection flows, to characterize them individually and search for correlations. We analyzed XMM-Newtomn data of a set of the brightest Seyfert 1 galaxies that went through an obscuration event: NGC 3783, NGC 3227, NGC 5548, and NGC 985. Our aim is to search for emission/absorption lines in short-duration spectra (∼ 10ks), to explore regions as close as the SMBH as the statistics allows for, and possibly catch transient phenomena. First we run a blind search to detect emission/absorption features, then we analyze their evolution with Residual Maps: we visualize simultaneously positive and negative residuals from the continuum in the time-energy plane, looking for patterns and relative time-scales. In NGC 3783 we were able to ascribe variations of the Fe Kα emission line to absorptions at the same energy due to clumps in the obscurer, whose presence is detected at >3σ, and to determine the size of the clumps. In NGC 3227 we detected a wind at ∼ 0.2c at ∼ 2σ, briefly appearing during an obscuration event.

THE STELLAR CONTENT OF OBSCURED GALACTIC GIANT H II REGIONS. VII. W3

Spectrophotometric distances in the K band have been reported by different authors for a number of obscured Galactic H II regions. Almost 50% of them show large discrepancies compared to the classical method using radial velocities measured in the radio spectral region. In order to provide a crucial test of both methods, we selected a target that does not present particular difficulty for any method and which has been measured by as many techniques as possible. The W3 star-forming complex, located in the Perseus arm, offers a splendid opportunity for such a task. We used the Near-Infrared Integral Field Spectrograph on the Frederick C. Gillett Gemini North telescope to classify candidate ""naked photosphere"" OB stars based on Two Micron All Sky Survey photometry. Two of the targets are revealed to be mid-O-type main-sequence stars leading to a distance of d = 2.20 kpc. This is in excellent agreement with the spectrophotometric distance derived in the optical band (d = 2.18 pc) and with a measurement of the W3 trigonometric parallax (d = 1.95 kpc). Such results confirm that the spectrophotometric distances in the K band are reliable. The radio-derived kinematic distance, on the contrary, gives a distance twice as large (d = 4.2 kpc). This indicates that this region of the Perseus arm does not follow the Galactic rotation curve, and this may also be the case for other H II regions for which discrepancies have been found.

H alpha spectropolarimetry of RY Tauri and PX Vulpeculae (Research Note)

Aims. To detect line effects using spectropolarimetry in order to find evidence of rotating disks and their respective symmetry axes in T Tauri stars. Methods. We used the IAGPOL imaging polarimeter along with the Eucalyptus-IFU to obtain spectropolarimetric measurements of the T Tauri stars RY Tau (two epochs) and PX Vul (one epoch). Evidence of line effects showing a loop in the Q-U diagram favors a compact rather than an extended source for the line photons in a rotating disk. In addition, the polarization position angle (PA) obtained using the line effect can constrain the symmetry axis of the disk. Results. RY Tau shows a variable H alpha double peak in 2004-2005 data. A polarization line effect is evident in the Q-U diagram for both epochs confirming a clockwise rotating disk. A single loop is evident in 2004 changing to a linear excursion plus a loop in 2005. Interestingly, the intrinsic PA calculated using the line effect is consistent between our two epochs (similar to 167 degrees). An alternative intrinsic PA computed from the interstellar polarization-corrected continuum and averaged between 2001-2005 yielded a PA similar to 137 degrees. This last value is closer to perpendicular to the observed disk direction (similar to 25 degrees), as expected from single scattering in an optically thin disk. For PX Vul, we detected spectral variability in H alpha along with non-variable continuum polarization when compared with previous data. The Q-U diagram shows a well-defined loop in H alpha associated with a counter-clockwise rotating disk. The symmetry axis inferred from the line effect has a PA similar to 91 degrees (with an ambiguity of 90 degrees). Our results confirm previous evidence that the emission line in T Tauri stars has its origin in a compact source scattered off a rotating accretion disk.

West (side) and north (rear) elevations, public housing, Cotton Tree Housing Estate, Maroochydore

This pilot project at Cotton Tree, Maroochydore, on two adjacent, linear parcels of land has one of the properties privately owned while the other is owned by the public housing authority. Both owners commissioned Lindsay and Kerry Clare to design housing for their separate needs which enabled the two projects to be governed by a single planning and design strategy. This entailed the realignment of the dividing boundary to form two approximately square blocks which made possible the retention of an important stand of mature paperbark trees and gave each block a more useful street frontage. The scheme provides seven two-bedroom units and one single-bedroom unit as the private component, with six single-bedroom units, three two-bedroom units and two three-bedroom units forming the public housing. The dwellings are deployed as an interlaced mat of freestanding blocks, car courts, courtyard gardens, patios and decks. The key distinction between the public and private parts of the scheme is the pooling of the car parking spaces in the public housing to create a shared courtyard. The housing climbs to three storeys on its southern edge and falls to a single storey on the north-western corner. This enables all units and the principal private outdoor spaces to have a northern orientation. The interiors of both the public and private units are skilfully arranged to take full advantage of views, light and breeze.
