How healthy is your âcommunity of practiceâ?
This article explores cultural change and situated approaches to learning as a basis for understanding developments in the daily life of the probation organization. These are highlighted in the concept of âcommunities of practiceâ that describes learning in the everyday activities of practitionersâ work. It is argued that the future can be changed by greater attention to context specific knowledge-in-use through practitioner research.</p
Coercion and social exclusion: the case of motivating change in drug-using offenders
Drug-using offenders have come to be a special focus for policy concerns within community justice. A more punitive penal climate and narrow conception of social exclusion may have created a policy environment that undermines the growth of treatment opportunities now available. The emphasis upon coercion in community justice treatment responses is questioned as it may inadvertently aggravate broader pressures towards custody within the sentencing climate. Since such penal environments aggravate factors associated with social exclusion it is argued that this may undermine rather than enhance individual motivation for change. Research evidence on drug treatment is examined and a case study from probation practice described. The complexities of both suggest that the current policy direction may need to do more to provide treatment when needed and enhance social networks rather than coerce change. This would complement rather than undermine approaches to practice that build on factors related to desistance and the existing resilience found in drug usersâ lives.</p
Solid-state time-to-pulse-height converter developed
Solid-state circuit produces an output pulse with an amplitude directly proportional to the time interval between two input pulses. It uses selected circuit options to achieve variable mode operation and a tunnel diode controls the charging time of a capacitor in proportion to the time interval being measured
MuLan: Towards a 1ppm muon lifetime measurement
The MuLan experiment will measure the lifetime of the positive muon to 1ppm.
Within the Standard Model framework, this will permit a determination of the
Fermi Constant to 0.5ppm. I present an update on our progress and achievements
to date.Comment: 3 pages, 1 figure, contribution to the proceedings of CIPANP 2006

Composite scalars at CERN LEP: Constraining technicolor theories
LEPI and LEPII data can be used to constrain technicolor models with light,
neutral pseudo-Nambu-Goldstone bosons, Pa. We use published limits on branching
ratios and cross sections for final states with photons, large missing energy,
jet pairs, and b bbar pairs to constrain the anomalous Pa Z0 Z0, Pa Z0 photon,
and Pa photon photon couplings. From these results, we derive bounds on the
size of the technicolor gauge group and the number of technifermion doublets in
models such as Low-scale Technicolor
Searching for Millisecond Pulsars: Surveys, Techniques and Prospects
Searches for millisecond pulsars (which we here loosely define as those with
periods 20 ms) in the Galactic field have undergone a renaissance in the
past five years. New or recently refurbished radio telescopes utilizing cooled
receivers and state-of-the art digital data acquisition systems are carrying
out surveys of the entire sky at a variety of radio frequencies. Targeted
searches for millisecond pulsars in point sources identified by the {\it Fermi}
Gamma-ray Space Telescope have proved phenomenally successful, with over 50
discoveries in the past five years. The current sample of millisecond pulsars
now numbers almost 200 and, for the first time in 25 years, now outnumbers
their counterparts in Galactic globular clusters. While many of these searches
are motivated to find pulsars which form part of pulsar timing arrays, a wide
variety of interesting systems are now being found. Following a brief overview
of the millisecond pulsar phenomenon, we describe these searches and present
some of the highlights of the new discoveries in the past decade. We conclude
with predictions and prospects for ongoing and future surveys.Comment: 16 pages, 3 figures, accepted for publication in Classical and

Context dependent learning: its value and impact for workplace education
Purpose â The purpose of this paper is to describe how a management development programme based on situated learning theory resulted in change for individuals, organisational culture and performance. The case study illustrates how new understandings about learning in the workplace and in higher education points towards the need to take account of the context in which learners utilise their knowledge and skills. Design/methodology/approach â Quantitative and qualitative strategies were used to provide an evaluation of the impact of a management development programme in a group of companies. A questionnaire, focus groups and semi-structured interviews were used to collect data on three cohorts of supervisors and middle managers at different stages of the programme. A triangulated approach was adopted towards data analysis that illuminated a broad and deep change process. Findings â Positive cultural change was a significant benefit to the host organisation from the training programme. It was apparent that training can move beyond individual development to bring about organisational gains. Research limitations/implications â Future research might adopt a longitudinal design and facilitate a co-researcher approach using studentsâ learning logs of workplace experiences. Practical implications â Situated approaches to learning in higher education and the workplace need to be developed further to enhance workplace performance. A proposal is made for âlearning consultantsâ to move between the two environments and facilitate knowledge exchange and improve understanding of the variety of learning contexts in business and educational settings.</p
Towards an innovation link between dynamic capabilities and sustainability strategy: options for emerging market companies
Over the last few years, there has been considerable scholarly interest in the strategic management concept of dynamic capabilities. During the same period, sustainability policies and strategies have also become a major focus for many companies. These two areas have resulted in major new innovative opportunities for companies, including those located in emerging markets. However to the present time, few studies have attempted to combine the growing scholarly topic of dynamic capabilities with the equally important topic of sustainability strategy in the context of emerging market companies. This paper links these two areas through the theoretical lens of innovation theory. It develops and proposes four main business options for companies, particularly those from emerging markets, from an innovation perspective. The paper contributes new knowledge by identifying and expanding on the innovation strategy links between dynamic capabilities and sustainability strategy. It offers theoretical insights into the nature of that connection in the context of companies from both developed and developing economies
