My character: enhancing future mindedness in young people: a feasibility study
The aim of the My Character project was to develop a better understanding of how interventions designed to develop character might enhance moral formation and futuremindedness in young people. Futuremindedness can be defined as an individual’s capacity to set goals and make plans to achieve them. Establishing goals requires considerable moral reflection, and the achievement of worthwhile aims requires character traits such as courage and the capacity to delay gratification.
The research team developed two new educational interventions – a website and a hard-copy journal – with the specific aim of developing future-mindedness. After development, the website and journal were piloted over a one-year period by over 1,000 11–14 year olds in six schools across England. Various research methods, including group interviews and case studies, were implemented to assess impact. In addition, a pilot RCT was conducted to assess the feasibility of using experimental methods to measure character.
The main findings from the research are that:
- Students benefit from opportunities in school to think about future-mindedness; this can be successfully taught through character education.
- Harnessing new technology, such as the Internet, offers exciting opportunities for character education.
- It is beneficial to investigate the impact of new character education resources in order to bring greater clarity about ‘what works’. The most useful approach is a mixed methods one that allows for triangulation of evidence.
- It is possible to run RCTs and other experimental research in schools to assess developmental projects of this kind, but applying the method in schools and creating suitable outcome measures present challenges for researchers.
- A positive indicator of the success is that five out of the six pilot schools have embedded My Character into their curriculum. In addition, many new schools, both in Britain and internationally, have started to use the website and / or journal.
This report describes the research, analyses the impact of My Character and concludes with recommendations for policy makers, practitioners and researchers embarking on similar projects. These recommendations include:
i) advocating that schools create space in the curriculum to teach future-mindedness through character education;
ii) enhancing traditional character education teaching methods with opportunities brought by Internet technologies;
iii) evaluating character education interventions using triangulated evidence drawn from a mixture of research methods
Combined observational and modeling based study of the aerosol indirect effect
International audienceThe indirect effect of aerosols via liquid clouds is investigated by comparing aerosol and cloud characteristics from the Global Climate Model CAM-Oslo to those observed by the MODIS instrument onboard the TERRA and AQUA satellites http://modis.gsfc.nasa.gov). The comparison is carried out for 15 selected regions ranging from remote and clean to densely populated and polluted. For each region, the regression coefficient and correlation coefficient for the following parameters are calculated: Aerosol Optical Depth vs. Liquid Cloud Optical Thickness, Aerosol Optical Depth vs. Liquid Cloud Droplet Effective Radius and Aerosol Optical Depth vs. Cloud Liquid Water Path. Modeled and observed correlation coefficients and regression coefficients are then compared for a 3-year period starting in January 2001. Additionally, global maps for a number of aerosol and cloud parameters crucial for the understanding of the aerosol indirect effect are compared for the same period of time. Significant differences are found between MODIS and CAM-Oslo both in the regional and global comparison. However, both the model and the observations show a positive correlation between Aerosol Optical Depth and Cloud Optical Depth in practically all regions and for all seasons, in agreement with the current understanding of aerosol-cloud interactions. The correlation between Aerosol Optical Depth and Liquid Cloud Droplet Effective Radius is variable both in the model and the observations. However, the model reports the expected negative correlation more often than the MODIS data. Aerosol Optical Depth is overall positively correlated to Cloud Liquid Water Path both in the model and the observations, with a few regional exceptions
Knightly virtues : enhancing virtue literacy through stories : research report
There is a growing consensus in Britain on the importance of character, and on the belief that the virtues that contribute to good character are part of the solution to many of the challenges facing modern society.
Parents, teachers and schools understand the need to teach basic moral virtues to pupils, such as honesty, self-control, fairness, and respect, while fostering behaviour associated with such virtues today. However, until recently, the materials required to help deliver this ambition have been missing in Britain.
The Knightly Virtues Programme, devised by the Jubilee Centre for Character and Virtues, aims to help solve this challenge. The programme, designed for 9 to 11 year olds, draws on selected classic stories to help teach moral character in schools.
This approach has proved to be popular with children and teachers, with more than 5,000 pupils from one hundred schools having participated in the programme so far. Fifty-five of these schools (including thirty Catholic and Church of England) and 3,272 pupils (1,517 of which attended a Church school) were directly involved in different stages of the research.
Based at the University of Birmingham, the Jubilee Centre houses leading academics dedicated to researching the various ways in which good character, which underpins the building blocks of society, can be developed. Recent research from the Centre has shown that the qualities that make up character can be learnt and taught, and suggests that we need a new emphasis on their importance in schools and in professional education.
This report from the Centre into the use of classic literature within schools sets out the ways in which the Knightly Virtues Programme is able to develop the virtue literacy of school pupils, and the extent to which an understanding and awareness of good moral character can make positive changes to behaviour.
The impact of the programme has been tested using several rigorous research methods, detailed in this report alongside their findings, which provide substantial empirical evidence for the effectiveness of using stories to develop virtue literacy
On the correlation between cosmic ray intensity and cloud cover
Various aspects of the connection between cloud cover (CC) and cosmic rays
(CR) are analysed. Many features of this connection indicate that there is no
direct causal connection between low cloud cover (LCC) and CR in spite of the
evident long-term correlation between them. However, most of these features are
indirect. If only some part of the LCC is connected and varies with CR, then
its value, obtained from the joint analysis of their 11-year variations, and
averaged over the globe, should be most likely less than 20%.
The most significant argument against a causal connection of CR and LCC is
the anticorrelation between LCC and the medium cloud cover (MCC). The scenario
of the parallel influence of the solar activity on the global temperature and
CC on one side and CR on the other, which can lead to the observed
correlations, is discussed and advocated.Comment: 30 pages, 10 figures, accepted for publication in Journal of

Decoupling limits of N=4 super Yang-Mills on R x S^3
We find new decoupling limits of N=4 super Yang-Mills (SYM) on R x S^3 with
gauge group SU(N). These decoupling limits lead to decoupled theories that are
much simpler than the full N=4 SYM but still contain many of its interesting
features. The decoupling limits correspond to being in a near-critical region,
near a point with zero temperature and critical chemical potentials. The new
decoupling limits are found by generalizing the limits of hep-th/0605234 to
include not only the chemical potentials for the SU(4) R-symmetry of N=4 SYM
but also the chemical potentials corresponding to the SO(4) symmetry. In the
decoupled theories it is possible to take a strong coupling limit in a
controllable manner since the full effective Hamiltonian is known. For planar
N=4 SYM on R x S^3 all the decoupled theories correspond to fully integrable
spin chains. We study the thermodynamics of the decoupled theories and find the
Hagedorn temperature for small and large values of the effective coupling. We
find an alternative formulation of the decoupling limits in the microcanonical
ensemble. This leads to a characterization of certain regimes of weakly coupled
N=4 SYM in which there are string-like states. Finally, we find a similar
decoupling limit for pure Yang-Mills theory, which for the planar limit leads
to a fully integrable decoupled theory.Comment: 48 pages, 1 figure; added references, published versio
Re-identification of individuals from images using spot constellations : a case study in Arctic charr (Salvelinus alpinus)
The long-term monitoring of Arctic charr in lava caves is funded by the Icelandic Research Fund, RANNÍS (research grant nos. 120227 and 162893). E.A.M. was supported by the Icelandic Research Fund, RANNÍS (grant no. 162893) and NERC research grant awarded to M.B.M. (grant no. NE/R011109/1). M.B.M. was supported by a University Research Fellowship from the Royal Society (London). C.A.L. and B.K.K. were supported by Hólar University, Iceland. The Titan Xp GPU used for this research was donated to K.T. by the NVIDIA Corporation.The ability to re-identify individuals is fundamental to the individual-based studies that are required to estimate many important ecological and evolutionary parameters in wild populations. Traditional methods of marking individuals and tracking them through time can be invasive and imperfect, which can affect these estimates and create uncertainties for population management. Here we present a photographic re-identification method that uses spot constellations in images to match specimens through time. Photographs of Arctic charr (Salvelinus alpinus) were used as a case study. Classical computer vision techniques were compared with new deep-learning techniques for masks and spot extraction. We found that a U-Net approach trained on a small set of human-annotated photographs performed substantially better than a baseline feature engineering approach. For matching the spot constellations, two algorithms were adapted, and, depending on whether a fully or semi-automated set-up is preferred, we show how either one or a combination of these algorithms can be implemented. Within our case study, our pipeline both successfully identified unmarked individuals from photographs alone and re-identified individuals that had lost tags, resulting in an approximately 4 our multi-step pipeline involves little human supervision and could be applied to many organisms.Publisher PDFPeer reviewe
Educating through Exemplars: Alternative Paths to Virtue
This paper confronts Zagzebski’s exemplarism with the intertwined debates over the conditions of exemplarity and the unity-disunity of the virtues, to show the advantages of a pluralistic exemplar-based approach to moral education (PEBAME). PEBAME is based on a prima facie disunitarist perspective in moral theory, which amounts to admitting both exemplarity in all respects and single-virtue exemplarity. First, we account for the advantages of PEBAME, and we show how two figures in
recent Italian history (Giorgio Perlasca and Gino Bartali) satisfy Blum’s definitions of ‘moral hero’ and ‘moral saint’ (1988). Then, we offer a comparative analysis of the effectiveness of heroes and saints with respect to character education, according to four criteria derived from PEBAME: admirability, virtuousness, transparency, and imitability. Finally, we conclude that both unitarist and disunitarist exemplars are fundamental to character education; this is because of the hero's superiority to the saint with respect to imitability, a fundamental feature of the exemplar for character
education
Cosmological Models and Renormalization Group Flow
We study cosmological solutions of Einstein gravity with a positive
cosmological constant in diverse dimensions. These include big-bang models that
re-collapse, big-bang models that approach de Sitter acceleration at late
times, and bounce models that are both past and future asymptotically de
Sitter. The re-collapsing and the bounce geometries are all tall in the sense
that entire spatial slices become visible to a comoving observer before the end
of conformal time, while the accelerating big-bang geometries can be either
short or tall. We consider the interpretation of these cosmological solutions
as renormalization group flows in a dual field theory and give a geometric
interpretation of the associated c-function as the area of the apparent
cosmological horizon in Planck units. The covariant entropy bound requires
quantum effects to modify the early causal structure of some of our big-bang
solutions.Comment: 26 pages, 11 figures, v2: improved discussion of entropy bounds,

Evaluation of aerosol number concentrations in NorESM with improved nucleation parameterization
The Norwegian Earth System Model (NorESM) is evaluated against atmospheric
observations of aerosol number concentrations. The model is extended to
include an explicit mechanism for new particle formation and secondary
organic aerosol (SOA) formation from biogenic precursors. Three nucleation
mechanisms are included in NorESM: binary sulfuric acid, activation type, and
organic nucleation. Ten model experiments are conducted to study the
sensitivity of the simulated aerosol number concentrations to nucleation, SOA
formation, black carbon size distribution and model meteorology. Simulated
vertical profiles are evaluated against 12 flight campaigns. Comparison of
monthly averaged aerosol number concentrations against 60 measurement sites
reveals that the model with explicit nucleation and SOA scheme performs well
in terms of correlation coefficient, R2 = 0.41 and a bias of −6%. NorESM
generally overestimates the amplitude of the seasonal cycle, possibly due to
underestimated sinks or exaggerated sensitivity to biogenic precursors
