Towards a framework for co-creating Open Scholarship
Fred Garnett,Nigel Ecclesfield
Research in Learning Technology , 2011, DOI: 10.3402/rlt.v19i3.7795
Abstract: A recent edition of ALT-J made a call for papers that looked at ‘theoretical approaches in digitally mediated environments'. A key part of this call was to use the Boyer Model of Scholarship as a frame of reference. The authors felt that there were limitations to this model which could be addressed in light of the recent moves to develop Open Scholarship. Our concern with Boyer is that he suggests a separation between researchers, who ‘build new knowledge through traditional research' and teachers who ‘study teaching models and practices to achieve optimal learning'. Boyer identifies four ‘Types' of Scholarship, those of Discovery, Integration, Application and Teaching (DIAT), but places the responsibility for ‘creative work in established field', with the traditional researcher role (Discovery). Furthermore this model implies a linear flow concerning how new knowledge becomes a part of teaching, implying that the teaching is mostly instructional, with a limited view of how new and emerging pedagogies might be utilised. The Learner-Generated Contexts Research Group has been concerned to develop a co-creation approach to learning and find this separation curious. We argue that using the Pedagogy, Andragogy, Heutagogy (PAH) Continuum enables more flexible approaches, through a mix of PAH, allowing for a wide range of technology uses, which also changes the relationship to research. We look at how we might both apply a co-creation approach to Boyer's model, inspired by the Open Scholar movement, and also make DIAT more iterative and less discrete. Consequently we have both extended Boyer's DIAT system to include Co-creating as an additional type and changed some ‘measures of performance' to enable an iterative process of scholarship to emerge which also involves learners. We also examine how network effects ‘enable generative network effects to occur' on scholarship and how applying Epistemic Cognition to evolving subject frameworks might enable the co-creation of research agendas. The co-creation model of Open Scholarship is presented in a table designed to simulate debate on this subject.
E-Learning and Public Value
Nigel Ecclesfield,Fred Garnett
ITALICS , 2006,
Abstract: Taking as its starting point the Grigg and Mager’s paper “Public value and Learning and Skills” (2005), the present paper seeks to explore the articulation of the concept of public value in the context of post compulsory education in the United Kingdom. Where Grigg and Mager and other authors focus on the provider’s role in developing public value through its activities, this paper looks at alternative articulations of the concept of public value to develop an outline of the contribution learners can make to public value through the media of ICT and e-learning. Drawing on previous work such as that of Garnett and O’Bierne (2005) and the perspectives of constructionist approaches in poverty and community studies, the potential role of ICT and e-learning in helping learners to create and record public value is outlined. A short outline of the development of this work, beyond this paper, is given.
Aggregate-then-Curate: how digital learning champions help communities nurture online content
Andrew Whitworth,Fred Garnett,Diana Pearson
Research in Learning Technology , 2012, DOI: 10.3402/rlt.v20i0.18677
Abstract: Informational resources are essential for communities, rooting them in their own history, helping them learn and solve problems, giving them a voice in decision-making and so on. For digital inclusion – and inclusion in the informational and democratic processes of society more generally – it is essential that communities retain the skills, awareness and motivation to create and manage their own informational resources.This article explores a model for the creation of online content that incorporates the different ways in which the quality and relevance of information can be assured. This model, “Aggregate-then-Curate” (A/C), was developed from earlier work concerning digital inclusion in UK online centres, models of informal e-learning and ecologies of resources. A/C shows how creating online content can be viewed as a 7-step process, initiated by individuals but bringing in “digital learning champions”, other community members and formal educational institutions at different stages. A/C can be used to design training to help build the capacity to manage community informational resources in an inclusive way. The article then discusses and evaluates MOSI-ALONG, a Joint Information Systems Committee (JISC) funded project founded on these ideas, which illustrates how A/C can be used to design training to help build the capacity to manage community informational resources in an inclusive way. This conclusion is supported by evaluations of the work done so far in MOSI-ALONG.
Arbitration cancers: analysis from two screening rounds for the Coventry, Solihull and Warwickshire screening service
S Garnett
Breast Cancer Research , 2011, DOI: 10.1186/bcr2964
Abstract: The study period covered two screening rounds. Arbitration records were reviewed and mammographic shape, size, position, cancer type and grade, and histological size were recorded. Both film and digital cases were included and compared. Descriptive statistics were produced comparing discordant and concordant cancers.A total of 128 arbitration cancers were analysed (3.6% of total cancers, n = 3,516). There were 5,635 total arbitrations of which 27% (n = 1,519) were assessed. A total of 8.4% were cancer. There were a higher number of smaller sized (1 to 15 mm) cancers in the arbitrated group, 61% compared with 48% in the concordant group. There was no difference between film and digital cancer size. More cancers appeared as lobular, tubular and DCIS in the arbitration group. There was an equal spread of calcification and mass type mammographic appearances.No previous study had specifically analysed arbitration (third-reader) cancers. This audit showed that lesion size is smaller, all cancer types are present and both calcifications and masses are equally represented. Digital cases did not show any smaller cancers for the discordant group. A future audit will be to look at the arbitration interval cancers; that is, when two readers have not recalled a subsequent false positive case, to assess the features that have been ignored.

Abstract: I review the current data on abundances in irregular galaxies, with special emphasis on recent results on C/O and Si/O from observations with the Hubble Space Telescope. The abundance data for He, C, N, and O in irregular galaxies is discussed in the context of models for the evolution of dwarf galaxies.
Economic Injustice as an Understanding of the Existence of Two Americas—Wealth and Poverty  [PDF]
Fred Bedell
Open Journal of Political Science (OJPS) , 2014, DOI: 10.4236/ojps.2014.43011
This essay speaks to government policies, the practices of the corporate sector, the inherited wealth of the few, and the consumptive behavior of the masses as the underlying causes of economic injustice. This is perceived as leading the country to an oligarchy.

Probing quantum nanostructures with near-field optical microscopy and (vice versa)
Garnett W. Bryant
Physics , 1997, DOI: 10.1063/1.120868
Abstract: A theory is presented to show how near-field optical microscopy can be used to probe quantum nanostructures. Calculations are done for a quantum dot. Results for different tip/dot configurations and sizes show that near-field excitation can enhance light-hole transitions, excite selection-rule breaking transitions with rates comparable to allowed transitions, and map electron-hole pair wave functions. Conversely, dot response can be used to characterize tip near-fields.
The Metallicity-Luminosity Relation, Effective Yields, and Metal Loss in Spiral and Irregular Galaxies
Donald R. Garnett
Physics , 2002, DOI: 10.1086/344301
Abstract: I present results on the correlation between galaxy mass, luminosity, and metallicity for a sample of spiral and irregular galaxies having well-measured abundance profiles, distances, and rotation speeds. Additional data for low surface brightness galaxies from the literature are also included for comparison. These data are combined to study the metallicity-luminosity and metallicity-rotation speed correlations for spiral and irregular galaxies. The metallicity luminosity correlation shows its familiar form for these galaxies, a roughly uniform change in the average present-day O/H abundance of about a factor 100 over 11 magnitudes in B luminosity. However, the O/H - V(rot) relation shows a change in slope at a rotation speed of about 125 km/sec. At faster V(rot), there appears to be no relation between average metallicity and rotation speed. At lower V(rot), the metallicity correlates with rotation speed. This change in behavior could be the result of increasing loss of metals from the smaller galaxies in supernova-driven winds. This idea is tested by looking at the variation in effective yield, derived from observed abundances and gas fractions assuming closed box chemical evolution. The effective yields derived for spiral and irregular galaxies increase by a factor of 10-20 from V(rot) approximately 5 km/sec to V(rot) approximately 300 km/sec, asympotically increasing to approximately constant y(eff) for V(rot) > 150 km/sec. The trend suggests that galaxies with V(rot) < 100-150 km/sec may lose a large fraction of their SN ejecta, while galaxies above this value tend to retain metals.
