The Search For Learning Community In Learner Paced Distance Education: Or, 'having Your Cake And Eating It, Too!'
University distance and e-learning programs generally follow one of two models.
Most dual mode institutions and some open universities follow a model of cohort
learning. Students start and terminate each course at the same time, and
proceed at the same pace. This model allows for occasional or regular group
based activities. The second model, referred to as learner paced, is based on
increased student independence. Students may start their courses at many points
during the year, and complete these at their own pace, depending on the
learner's circumstances and interests. It is much more challenging to integrate
group based activities in this learner paced model. This study is situated in a
university that supports continuous intake and learner pacing in its undergraduate
programs. Athabasca University is investigating the feasibility and effectiveness of
adding collaborative and cooperative learning activities to this model. The report
summarises a study of learner interactions in the context of learner paced
courses delivered by the University. Following a review of relevant literature, the
study reports on interviews with Athabasca University faculty and external
distance education experts, describes results from an online survey of
undergraduate students, and documents how these findings may be
operationalised at the University. An extensible model of community based
learning support is proposed to utilise new social computing capabilities of the
web, and to permit learner-learner interaction in a scaleable and cost effective
manner, while retaining learner pacing
The Right to Existence in Developing Countries: Basic Income in East Timor
In this article we consider the potential of a Basic Income (BI) as a mechanism for promoting well-integrated and autonomous social and productive development in newly independent Democratic Republic of East Timor, and for expanding the freedom of this country's population that is struggling to throw off the bitter legacy of colonial and postcolonial dispossession and violence. We briefly outline the main social and economic problems faced by the new Democratic Republic of East Timor. Then we argue that a BI financed by oil and natural gas revenues could play a major role in combating these problems
Experimental Status of Neutrino Physics
After a fascinating phase of discoveries, neutrino physics still has a few
mysteries such as the absolute mass scale, the mass hierarchy, the existence of
CP violation in the lepton sector and the existence of right-handed neutrinos.
It is also entering a phase of precision measurements. This is what motivates
the NUFACT 11 conference which prepares the future of long baseline neutrino
experiments. In this paper, we report the status of experimental neutrino
physics. We focus mainly on absolute mass measurements, oscillation parameters
and future plans for oscillation experiments

Mapping localized surface plasmons within silver nanocubes using cathodoluminescence hyperspectral imaging
Localized surface plasmons within silver nanocubes less than 50 nm in size are investigated using high resolution cathodoluminescence hyperspectral imaging. Multivariate statistical analysis of the multidimensional luminescence dataset allows both the identification of distinct spectral features in the emission and the mapping of their spatial distribution. These results show a 490 nm peak emitted from the cube faces, with shorter wavelength luminescence coming from the vertices and edges; this provides direct experimental confirmation of theoretical predictions

Model-independent evidence for contributions to decays
The data sample of decays acquired with the
LHCb detector from 7 and 8~TeV collisions, corresponding to an integrated
luminosity of 3 fb, is inspected for the presence of or
contributions with minimal assumptions about
contributions. It is demonstrated at more than 9 standard deviations that
decays cannot be described with
contributions alone, and that contributions play a dominant role in
this incompatibility. These model-independent results support the previously
obtained model-dependent evidence for charmonium-pentaquark
states in the same data sample.Comment: 21 pages, 12 figures (including the supplemental section added at the

Study of J /ψ production in Jets
The production of J/ψ mesons in jets is studied in the forward region of proton-proton collisions using data collected with the LHCb detector at a center-of-mass energy of 13 TeV. The fraction of the jet transverse momentum carried by the J/ψ meson, z(J/ψ)≡pT(J/ψ)/pT(jet), is measured using jets with pT(jet)>20 GeV in the pseudorapidity range 2.5<η(jet)<4.0. The observed z(J/ψ)distribution for J/ψ mesons produced in b-hadron decays is consistent with expectations. However, the results for prompt J/ψ production do not agree with predictions based on fixed-order nonrelativistic QCD. This is the first measurement of the pT fraction carried by prompt J/ψ mesons in jets at any experiment
