    Het systematisch en massaal doden van pas uitgekomen mannelijke kuikens, hoe ethisch is dat? En zijn er geen alternatieven? Deze twee vragen staan in deze bijdrage centraal. Op basis van de dierethische waarden ‘intrinsieke waarde van het dier’, dierenwelzijn en vrijheid om natuurlijk gedrag te vertonen, wordt geconcludeerd dat de gangbare praktijk ethisch zeer problematisch is, ook al worden de gedode haantjes in Nederland voor diervoeder gebruikt. Deze praktijk is vergeleken met seksen en selecteren van het 18-dagen oude embryo. Het verschil wordt ethisch niet groot geacht. Deze praktijk is gevolg van een eenzijdig op doelmatigheid gerichte ontwikkeling waarvoor de overheid en de samenleving als geheel medeverantwoordelijkheid voor dragen. Een echte oplossing vereist een systeemomslag of ten minste de ontwikkeling van geheel nieuwe technieken die het massale doden van eendagshaantjes of bebroede eieren vermijde

    Spiritual Care in a Hospital Setting: Nurses’ and Patients’ Perspectives

    The Trent Universities Interprofessional Learning in Practice (TUILIP) project aimed to establish interprofessional learning (IPL) for healthcare students in clinical practice settings. Ten IPL facilitators were employed in eight varied practice setting pilot sites for up to a year to research, develop and run locally appropriate, sustainable IPL initiatives. Following the pilot phase, a qualitative evaluation was conducted in each site by means of interviews or focus groups with all key stakeholders (facilitators, clinical managers, practitioners, students, service users, carers). Data collection was guided by Kirkpatrick’s evaluation framework (1996), which focuses upon participant reactions, and their perceptions of learning, behaviour change and sustainable impact. In keeping with this framework, participants were asked to discuss their experiences of TUILIP in their placement setting (including its facilitation), and their opinions about its impact and success in terms of learning, behaviour change and sustainability. We report a subset of evaluation results relating to the roles of the facilitator, facilitation processes, experiences and challenges, personal and professional impact upon facilitators, and implications for IPL projects in practice. Facilitation tasks included preparing the ground, earning credibility, gathering ideas, researching feasibility, developing initiatives, involving service users, trialling and embedding initiatives. Facilitators were faced with challenges such as getting a focus, time limitations and dealing with logistics. They reported highs (being a fly on the wall, protected time, their educational role, and a sense of satisfaction) and lows (loneliness, frustration and fear of failure), but considered they had developed personally and professionally as a result of their experiences. Results demonstrated the complexity and demands of establishing and facilitating IPL initiatives in practice settings. Facilitation was time-consuming and effortful and did not always achieve its aims, but was a source of satisfaction and personal development. These findings suggest higher education institutions and practice settings should consider carefully the selection, preparation and support for facilitators of practice-based IPL, as well as how to engage local practitioners and service users, and embed changes in the clinical setting

    Adsorption and two-body recombination of atomic hydrogen on 3^3He-4^4He mixture films

    We present the first systematic measurement of the binding energy EaE_a of hydrogen atoms to the surface of saturated 3^3He-4^4He mixture films. EaE_a is found to decrease almost linearly from 1.14(1) K down to 0.39(1) K, when the population of the ground surface state of 3^3He grows from zero to 6×10146\times10^{14} cm2^{-2}, yielding the value 1.2(1)×10151.2(1)\times 10^{-15} K cm2^2 for the mean-field parameter of H-3^3He interaction in 2D. The experiments were carried out with overall 3^3He concentrations ranging from 0.1 ppm to 5 % as well as with commercial and isotopically purified 4^4He at temperatures 70...400 mK. Measuring by ESR the rate constants KaaK_{aa} and KabK_{ab} for second-order recombination of hydrogen atoms in hyperfine states aa and bb we find the ratio Kab/KaaK_{ab}/K_{aa} to be independent of the 3^3He content and to grow with temperature.Comment: 4 pages, 4 figures, all zipped in a sigle file.

    Over zorgvuldige veehouderij : veel instrumenten, één concert

    Get PDF
    "Onder een zorgvuldige veehouderij verstaan we een modern ingerichte en economisch vitale veehouderij, die garant staat voor een goede omgang met dieren, een nauwkeurige naleving van professionele waarden en waarmee een goede boterham kan worden verdiend." In totaal 62 onderzoekers beschrijven in 30 essays actuele inzichten, ieder vanuit hun kijk op de verschillende aspecten van de veehouderij. De breedte van die visie is onontbeerlijk. Er is niet één oplossing, maar er zijn vele wegen die naar Rome leiden. Een simpel spoorboekje, dat de kortste route geeft naar de plaats van bestemming, is er in dit geval niet. . . . Met deze essaybundel hoopt Wageningen UR het debat over de toekomst van de veehouderij te verrijken. Met de kennis die we hebben of kunnen genereren willen we laten zien dat het mogelijk is om samen met bedrijfsleven, overheid en (bezorgde) burgers oplossingen uit te werken voor de prangende maatschappelijke vraagstukken. Want: 'kennisinstellingen en hun leden moeten een actieve rol spelen in de maatschappelijke discussie', aldus Rudy Rabbinge en Pieter Winsemius in hun voorwoord."(Van Wageningen UR nieuws http://www.wur.nl/NL/nieuwsagenda/nieuws/P004.htm

    Wannier-function description of the electronic polarization and infrared absorption of high-pressure hydrogen

    Full text link
    We have constructed maximally-localized Wannier functions for prototype structures of solid molecular hydrogen under pressure, starting from LDA and tight-binding Bloch wave functions. Each occupied Wannier function can be associated with two paired protons, defining a ``Wannier molecule''. The sum of the dipole moments of these ``molecules'' always gives the correct macroscopic polarization, even under strong compression, when the overlap between nearby Wannier functions becomes significant. We find that at megabar pressures the contributions to the dipoles arising from the overlapping tails of the Wannier functions is very large. The strong vibron infrared absorption experimentally observed in phase III, above ~ 150 GPa, is analyzed in terms of the vibron-induced fluctuations of the Wannier dipoles. We decompose these fluctuations into ``static'' and ``dynamical'' contributions, and find that at such high densities the latter term, which increases much more steeply with pressure, is dominant.Comment: 17 pages, two-column style with 14 postscript figures embedded.
