Standardizing and Disseminating Knowledge: The Role of the OECD in Global Governance

If ‘knowledge is power’, it is unsurprising that the production, legitimation, and application of social scientific knowledge, not least that which was designed to harness social organization to economic growth, is a potentially contentious process. Coping with, adapting to, or attempting to shape globalization has emerged as a central concern of policy-makers who are, therefore, interested in knowledge to assist their managerial activities. Thus, an organization that can create, synthesize, legitimate, and dissemination useful knowledge can play a significant role in the emerging global governance system. The OECD operates as one important site for the construction, standardization, and dissemination of transnational policy ideas. OECD staff conducts research and produces a range of background studies and reports, drawing on disciplinary knowledge (typically economics) supplemented by their ‘organizational discourses’. This paper probes the contested nature of knowledge production and attempts to evaluate the impact of the OECD’s efforts to produce globally applicable policy advice. Particular attention is paid to important initiatives in the labour market and social policy fields—the Jobs Study and Babies and Bosses

The effects of reactor irradiation on Santowax OMP at 610°F and 750°F

"September 1963.""IDO-11, 107."Also issued by the first author as an Sc. D. thesis, Massachusetts Institute of Technology, Dept. of Nuclear Engineering, 1964Includes bibliographical referencesSantowax OMP has been irradiated in the M.I.T. In-Pile Loop Facility at 610°F and at 750°F. At both temperatures the loop was operated in a transient phase and a steady-state-HB phase. In the transient phase, unirradiated material was allowed to degrade to 60 w/o DP. In the steadystate- HB phase, the HB content of the coolant was maintained constant at about 33 w/o by the removal and distillation of samples and the replacement of the HB by unirradiated material before returning the samples to the loop. Neutron and gamma ray doses were measured with adiabatic calorimeters and foil monitors. The average dose rate to the coolant in the core region of the in-pile section was about 0. 5 watts/gm, of which 37% was due to fast neturon interactions and 63% to gamma ray interactions. Terphenyl concentrations were measured by gas chromatography and HB concentrations by distillation.Analysis of the transient phase terphenyl concentration and absorbed dose data showed that first order kinetics provided an adequate description of the degradation rate of the terphenyls. At 610°F no significant difference in the stabilities of the terphenyl issomers was found and the overall degradation rate of the coolant was G*(-omp) = G(-omp)/Comp = 0. 26 ± 0. 01 molecules of terphenyl degraded per 100 ev absorbed in the terphenyls. At 750°F the terphenyl isomer stabilities were in the order para>meta>ortho. After corrections for out-of-pile pyrolysis the overall degradation rate of the coolant was G*(-omp) = 0. 49 ± 0. 02. The results are compared to those of other investigations. For the 610°F irradiation the radiolytic gas generation rate was G(total gas) = 0.037 ± 0.003 molecules of gas produced per 100 ev absorbed in the coolant mixture, the principal product being hydrogen.During the 750°F irradiation the generation rate was G(total gas) = 0.105 ± 0.008, with a marked increase in the evolution of methane. Physical property measurements included density, viscosity, specific heat, thermal conductivity, number average molecular weight, gas solubility, carbon-hydrogen content and ash content. The increase in viscosity with increasing DP concentration was significantly less for the 750°F irradiation than for the 610*F irradiation. Heat transfer measurements showed that standard correlations could be used to determine the heat transfer rates using the physical properties of the irradiated coolant. The correlation obtained for the data of both irradiations was Nu = 0. 0079(Re)0.9(Pr) 0 . 4 ± 10%. No evidence of scale buildup on the heat transfer surfaces was observed over the entire period of operation of the experiment. The results of preliminary measurements with a fouling probe are also reported.M.I.T.

Mapping the depleted area of silicon diodes using a micro-focused X-ray beam

For the Phase-II Upgrade of the ATLAS detector at CERN, the current ATLAS Inner Detector will be replaced with the ATLAS Inner Tracker. The ATLAS Inner Tracker will be an all-silicon detector, consisting of a pixel tracker and a strip tracker. Sensors for the ITk strip tracker are required to have a low leakage current up to bias voltages of -700 V to maintain a low noise and power dissipation. In order to minimise sensor leakage currents, particularly in the high-radiation environment inside the ATLAS detector, sensors are foreseen to be operated at low temperatures and to be manufactured from wafers with a high bulk resistivity of several k{\Omega} cm. Simulations showed the electric field inside sensors with high bulk resistivity to extend towards the sensor edge, which could lead to increased surface currents for narrow dicing edges. In order to map the electric field inside biased silicon sensors with high bulk resistivity, three diodes from ATLAS silicon strip sensor prototype wafers were studied with a monochromatic, micro-focused X-ray beam at the Diamond Light Source. For all devices under investigation, the electric field inside the diode was mapped and its dependence on the applied bias voltage was studied. The findings showed that the electric field in each diode under investigation extended beyond its bias ring and reached the dicing edge

Wild to domestic and back again: the dynamics of fallow deer management in medieval England (c.11th-16th century AD)

This paper presents the results of the first comprehensive scientific study of the fallow deer, a non-native species whose medieval-period introduction to Britain transformed the cultural landscape. It brings together data from traditional zooarchaeological analyses with those derived from new ageing techniques as well as the results of a programme of radiocarbon dating, multi-element isotope studies and genetic analyses. These new data are here integrated with historical and landscape evidence to examine changing patterns of fallow deer translocation and management in medieval England between the 11th and 16th century AD

Hydrogeomorphology of the Hyporheic Zone: Stream Solute and Fine Particle Interactions With a Dynamic Streambed

Hyporheic flow in streams has typically been studied separately from geomorphic processes. We investigated interactions between bed mobility and dynamic hyporheic storage of solutes and fine particles in a sand-bed stream before, during, and after a flood. A conservatively transported solute tracer (bromide) and a fine particles tracer (5 μm latex particles), a surrogate for fine particulate organic matter, were co-injected during base flow. The tracers were differentially stored, with fine particles penetrating more shallowly in hyporheic flow and retained more efficiently due to the high rate of particle filtration in bed sediment compared to solute. Tracer injections lasted 3.5 h after which we released a small flood from an upstream dam one hour later. Due to shallower storage in the bed, fine particles were rapidly entrained during the rising limb of the flood hydrograph. Rather than being flushed by the flood, we observed that solutes were stored longer due to expansion of hyporheic flow paths beneath the temporarily enlarged bedforms. Three important timescales determined the fate of solutes and fine particles: (1) flood duration, (2) relaxation time of flood-enlarged bedforms back to base flow dimensions, and (3) resulting adjustments and lag times of hyporheic flow. Recurrent transitions between these timescales explain why we observed a peak accumulation of natural particulate organic matter between 2 and 4 cm deep in the bed, i.e., below the scour layer of mobile bedforms but above the maximum depth of particle filtration in hyporheic flow paths. Thus, physical interactions between bed mobility and hyporheic transport influence how organic matter is stored in the bed and how long it is retained, which affects decomposition rate and metabolism of this southeastern Coastal Plain stream. In summary we found that dynamic interactions between hyporheic flow, bed mobility, and flow variation had strong but differential influences on base flow retention and flood mobilization of solutes and fine particulates. These hydrogeomorphic relationships have implications for microbial respiration of organic matter, carbon and nutrient cycling, and fate of contaminants in streams

Pain experience, expression and coping in boys and young men with Duchenne muscular dystrophy – a pilot study using mixed methods

Introduction: There is limited research exploring the pain experience of boys and young men with Duchenne Muscular Dystrophy. Methods: We conducted a mixed-methods pilot study to assess the feasibility of using particular measures of pain, pain coping and quality of life within semi-structured interviews with boys and young men with Duchenne Muscular Dystrophy and a postal survey of their parents. Non-probability, convenience sampling was used. Results: Twelve young men aged 11 to 21 years (median 15 years), three of whom were still ambulant, and their parents / guardians were recruited. The measures used were acceptable to the young men and demonstrated potential to provide useful data. Two-thirds of young men suffered from significant daily pain which was associated with reduced quality of life. Pain complaints were largely kept within the family. Young men's pain-coping strategies were limited by their restricted physical abilities. Statistical power based on these preliminary results suggests a study of approximately 50 boys/young men which appears feasible. Conclusions: Further study is needed to explore acceptable and effective methods of pain management in this population and ways of enhancing pain-coping strategies. In clinical practice, assessment of pains and discomfort should form part of all routine consultations

Characterization of Fast Ion Transport via Position-Dependent Optical Deshelving

Ion transport is an essential operation in some models of quantum information processing, where fast ion shuttling with minimal motional excitation is necessary for efficient, high-fidelity quantum logic. While fast and cold ion shuttling has been demonstrated, the dynamics and specific trajectory of an ion during diabatic transport have not been studied in detail. Here we describe a position-dependent optical deshelving technique useful for sampling an ion's position throughout its trajectory, and we demonstrate the technique on fast linear transport of a $^{40}\text{Ca}^+$ ion in a surface-electrode ion trap. At high speed, the trap's electrode filters strongly distort the transport potential waveform. With this technique, we observe deviations from the intended constant-velocity (100 m/s) transport: we measure an average speed of 83(2) m/s and a peak speed of 251(6) m/s over a distance of 120 $\mu$

Double indexing overcomes inaccuracies in multiplex sequencing on the Illumina platform

Due to the increasing throughput of current DNA sequencing instruments, sample multiplexing is necessary for making economical use of available sequencing capacities. A widely used multiplexing strategy for the Illumina Genome Analyzer utilizes sample-specific indexes, which are embedded in one of the library adapters. However, this and similar multiplex approaches come with a risk of sample misidentification. By introducing indexes into both library adapters (double indexing), we have developed a method that reveals the rate of sample misidentification within current multiplex sequencing experiments. With ~0.3% these rates are orders of magnitude higher than expected and may severely confound applications in cancer genomics and other fields requiring accurate detection of rare variants. We identified the occurrence of mixed clusters on the flow as the predominant source of error. The accuracy of sample identification is further impaired if indexed oligonucleotides are cross-contaminated or if indexed libraries are amplified in bulk. Double-indexing eliminates these problems and increases both the scope and accuracy of multiplex sequencing on the Illumina platform

Interferometric Study of Ionospheric Plasma Irregularities in Regions of Phase Scintillations and HF Backscatter

We investigate the nature of small-scale irregularities observed in the cusp by the Twin Rockets to Investigate Cusp Electrodynamics-2 (TRICE-2) in regions of enhanced phase scintillations and high-frequency coherent radar backscatter. We take advantage of the fact that the irregularities were detected by spatially separated probes, and present an interferometric analysis of both the observed electron density and electric field fluctuations. We provide evidence that fluctuations spanning a few decameters to about a meter have low phase velocity in the plasma reference frame and are nondispersive, confirming that decameter-scale irregularities follow the E × B velocity. Furthermore, we show that these “spatial” structures are intermittent and prominent outside of regions with strongest precipitation. The observations are then discussed in the context of possible mechanisms for irregularity creation.publishedVersio
