Sustainable development projects: explicit and acroamatic story telling as part of a new ‘project ethnography’

This paper constitutes an attempt to find a means to represent multiple stories in the strong narrative of conventional sustainable development (SD) projects. The author’s experience of such projects in various parts of the world indicates that they have a tendency to arise from and reflect a dominant mindset, placing the SD project in what can be a working environment which is inimical to the very ideals which SD is supposed to represent. Short termism and value for money drive project formats and objectives whilst counter narratives and alternative stories arising from stakeholders in such projects are often ignored. Yet these alternative threads often contain strong SD messages of their own and could, if effectively utilised, enhance the SD project process. This paper sets out the case for a new field – ‘project ethnography’ – allied with the growing use of meta analysis to compare project ‘stories’. The paper presents preliminary findings using an analytical framework to facilitate an ethnographic analysis and draw out the stories that those working in such projects can tell. The analysis focuses on some SD projects in the Mediterranean which reinforces the view of the authors that the conventional model of SD project organisation and delivery often contains within itself alternative understandings – understandings which the authors regard as stories in collision with the presenting and accepted project narrative, but at the same time valuable in richness of experience and perspective which can be drawn upon for informing SD project design and implementation

Absolute resonance strengths in the 6,7Li(alpha,gamma)10,11B reactions

The absolute strengths of the Ea=1175keV resonance in the 6Li(a,g)10B reaction and of the Ea=814 keV resonance in the 7Li(a,g)11B reaction have been measured to $\omega\gamma$=366+-38 meV and $\omega\gamma$=300+-32 meV, respectively, in good agreement with previous values. These resonances can be used to measure the absolute acceptance of the recoil separator ERNA to a precision of about 10%.Comment: 6 pages, 5 figures, to appear in European Physical Journal

Valence transition in the periodic Anderson model

A very rich phase diagram has recently been found in CeCu$_{2}$Si$_{2}$ from high pressure experiments where, in particular, a transition between an intermediate valence configuration and an integral valent heavy fermion state has been observed. We show that such a valence transition can be understood in the framework of the periodic Anderson model. In particular, our results show a breakdown of a mixed-valence state which is accompanied by a drastic change in the \textit{f} occupation in agreement with experiment. This valence transition can possibly be interpreted as a collapse of the large Fermi surface of the heavy fermion state which incorporates not only the conduction electrons but also the localized \textit{f} electrons. The theoretical approach used in this paper is based on the novel projector-based renormalization method (PRM). With respect to the periodic Anderson model, the method was before only employed in combination with the basic approximations of the well-known slave-boson mean-field theory. In this paper, the PRM treatment is performed in a more sophisticated manner where both mixed as well as integral valent solutions have been obtained. Furthermore, we argue that the presented PRM approach might be a promising starting point to study the competing interactions in CeCu$_{2}$Si$_{2}$ and related compounds.Comment: 9 pages, 3 figures included; v2: completely revised and extended versio

Evidence for an Excess of Soft Photons in Hadronic Decays of Z^0

Soft photons inside hadronic jets converted in front of the DELPHI main tracker (TPC) in events of qqbar disintegrations of the Z^0 were studied in the kinematic range 0.2 < E_gamma < 1 GeV and transverse momentum with respect to the closest jet direction p_T < 80 MeV/c. A clear excess of photons in the experimental data as compared to the Monte Carlo predictions is observed. This excess (uncorrected for the photon detection efficiency) is (1.17 +/- 0.06 +/- 0.27) x 10^{-3} gamma/jet in the specified kinematic region, while the expected level of the inner hadronic bremsstrahlung (which is not included in the Monte Carlo) is (0.340 +/- 0.001 +/- 0.038) x 10^{-3} gamma/jet. The ratio of the excess to the predicted bremsstrahlung rate is then (3.4 +/- 0.2 +/- 0.8), which is similar in strength to the anomalous soft photon signal observed in fixed target experiments with hadronic beams.Comment: 37 pages, 9 figures, Accepted by Eur.

This report summarizes the vegetable variety evaluations of the Horticulture Department of the University of Alaska, Fairbanks, 1982. Variety trials were all conducted at the Agricultural Experiment Station’s research farm at Fairbanks. The objective of this research is to select varieties of vegetables that are adapted to this environment. It also identifies types whose adaptability may be improved through development of improved cultural techniques. The selection effort is directed at finding varieties useful to both the commercial growers and home gardeners.Introduction -- Table 1:Climatic Data for the Fairbanks Growing Season: 1981, 1982, and the Long-Term Average -- Table 2: Broccoli Variety Trials, Upland, 1982 -- Table 3: Brussels Sprouts Variety Trials, Upland, 1982 -- Table 4: Cabbage Variety Trials, Upland, 1982 -- Table 5: Carrot Variety Trials, Bottomland, 1982 -- Table 6: Cauliflower Variety Trials, Upland, 1982 -- Table 7: Celery Variety Trials, Upland, 1982 -- Table 9: Eggplant Variety Trials, Upland, 1982 -- Table 10: Green Pea Variety Trials, Bottomland, 1982 -- Table 11: Crisphead Lettuce Variety Trials, Bottomland, 1982 -- Table 12: Pepper Variety Trials, Upland, 1982 -- Table 13: Potato Variety Trials, Bottomland Peat, 1982 -- Table 14: Pumpkin Variety Trials, Upland, 1982 -- Table 15: Snapbean Variety Trials, Upland, 1982 -- Table 16: Summer Squash Variety Trials, Upland, 1982 -- Table 17: Winter Squash Variety Trials, Upland, 1982 -- Table 18: Sweet Corn Variety Trials, Upland, 1982 -- Table 19: Tomato Variety Trials, Upland, 1982 -- Table 20: Container Tomato Variety Trials, 1982 -- Table 12: Miscellaneous Vegetables Tested -- Seed Source

Some Cavitation Experiments with Dilute Polymer Solutions

A previous paper (Brennen (1968b)) reported the observation and analysis of wave patterns on the surface of fully developed cavities behind a series of axisymmetric headforms in No.2 water tunnel at Ship Division, NPL. Comparison of theory and experiment appeared to confirm that these waves, which appeared a short distance after separation, grew in amplitude as they were convected downstream and then under certain conditions broke up into turbulence, were the amplified result of a select frequency instability in the separated or cavity surface boundary layer. The small vertical tunnel (figure 1) was employed to study and extend observation of the same phenomenon to smaller headforms and Reynolds numbers. An additional intention was to investigate the effect of small quantities of polymer additive on the behaviour of this instability. But, a more dramatic phenomenon was manifest with the addition of these drag-reducing chemicals, leaving the original objective unattainable
