Innovation and social enterprise activity in third sector organisations
There is a growing interest in the role of social enterprises and third sector organisations in delivering a range of services and many claims made about their innovative potential. There is therefore a need to examine the approaches to innovation. This paper examines the different sources of innovation amongst third sector organisations that are involved in social enterprise activity. Drawing on three case studies of charities with a majority of their income from social enterprise activity, the paper explores what innovation can mean in the current policy environment and also identifies the diverse sources of innovation. These can relate to the products or services and to the process of delivering these. Social enterprise activity can also create a space for innovation in terms of positioning services for new users/funders, and can reflect a changing paradigm of delivering services. The paper concludes by raising questions regarding the extent of innovative activity and the extent to which innovation is encouraged or hindered by current political and institutional context
Electron Spin Resonance at the Level of 10000 Spins Using Low Impedance Superconducting Resonators
We report on electron spin resonance (ESR) measurements of phosphorus donors
localized in a 200 square micron area below the inductive wire of a lumped
element superconducting resonator. By combining quantum limited parametric
amplification with a low impedance microwave resonator design we are able to
detect around 20000 spins with a signal-to-noise ratio (SNR) of 1 in a single
shot. The 150 Hz coupling strength between the resonator field and individual
spins is significantly larger than the 1 - 10 Hz coupling rates obtained with
typical coplanar waveguide resonator designs. Due to the larger coupling rate,
we find that spin relaxation is dominated by radiative decay into the resonator
and dependent upon the spin-resonator detuning, as predicted by Purcell
Spin Coherence and N ESEEM Effects of Nitrogen-Vacancy Centers in Diamond with X-band Pulsed ESR
Pulsed ESR experiments are reported for ensembles of negatively-charged
nitrogen-vacancy centers (NV) in diamonds at X-band magnetic fields
(280-400 mT) and low temperatures (2-70 K). The NV centers in synthetic
type IIb diamonds (nitrogen impurity concentration ~ppm) are prepared with
bulk concentrations of cm to cm
by high-energy electron irradiation and subsequent annealing. We find that a
proper post-radiation anneal (1000C for 60 mins) is critically
important to repair the radiation damage and to recover long electron spin
coherence times for NVs. After the annealing, spin coherence times of T~ms at 5~K are achieved, being only limited by C nuclear spectral
diffusion in natural abundance diamonds. At X-band magnetic fields, strong
electron spin echo envelope modulation (ESEEM) is observed originating from the
central N nucleus. The ESEEM spectral analysis allows for accurate
determination of the N nuclear hypefine and quadrupole tensors. In
addition, the ESEEM effects from two proximal C sites (second-nearest
neighbor and fourth-nearest neighbor) are resolved and the respective C
hyperfine coupling constants are extracted.Comment: 10 pages, 5 figure
Experience of a Recruit in the United States Army
War Department: The Adjutant General\u27s Office, Washington DC, May 5, 1916:
With the view of presenting to all concerned the actual experiences of a young man who enlists in tho United States Army, the following extracts from the Columbus Citizen, of Columbus, Ohio, are republished. This tale of human interest was published in the newspaper mentioned from March 31 to April 4, 1916, and, as stated in the editor\u27s note, depicts the actual experiences of a newspaper reporter detailed to find out and tell the Citizen readers how the United States prepares its soldiers for duty. These articles are republished without comment, as it is obvious that comment is unnecessary.
