Forbedrede udearealer i økologisk Ìgproduktion
Med henblik pĂĽ at styrke forsknings- og udviklingsindsatsen inden for økologisk fjerkrĂŚproduktion, blev det muligt med finansiering fra Direktoratet for FødevareErhverv, i 2001 at pĂĽbegynde udviklingsprojektet âFjerkrĂŚets udearealer ved økologisk produktionâ. Projektet tog udgangspunkt i en rĂŚkke interessetilkendegivelser fra fjerkrĂŚproducenter og andre interesserede indenfor økologisk fjerkrĂŚproduktion, og projektet blev planlagt i et samarbejde mellem
⢠Brancheforeningen for Ăkologiske Ăg- og FjerkrĂŚproducenter
⢠Dansk ErhvervsfjerkrÌ
⢠Landsforeningen for Ăkologisk Jordbrug
⢠Landskontoret for FjerkrÌrüdgivning og
⢠Danmarks JordbrugsForskning som koordinerende partner
Det var en grundlĂŚggende ide i projektet at tage udgangspunkt i de medvirkende producenters allerede opbyggede erfaringsgrundlag og idĂŠer til videre udvikling.
En del af projektet tog udgangspunkt i en interessetilkendegivelse fra en gruppe ĂŚgproducenter, âHønsegĂĽrdenâ A.m.b.a., der havde et samarbejde om videndeling og afsĂŚtning. Producenterne havde i samarbejde med Landskontoret for FjerkrĂŚrĂĽdgivning identificeret udearealerne (hønsegĂĽrdene) som et centralt omrĂĽde, hvor der var behov for yderligere viden om den mest hensigtsmĂŚssige indretning og drift i forhold til sĂĽvel hønernes produktivitet og velfĂŚrd som miljøeffekter. Rapporten beskriver de opnĂĽede resultater fra denne del af projektet og pĂĽ grundlag heraf gives anbefalinger til, hvorledes udearealerne mest hensigtsmĂŚssigt bør indrettes
Febrile Convulsions as a Problem in Waiting Times
A simple hypothesis on the occurrence of febrile convulsions is posed. This is (1) that certain children are genetically predisposed, and (2) that for such children, the probability of the first attack occurring in year 1, 2, etc., is essentially constant up to the end of the period during which the attacks can take place. These assumptions lead to a probability model which agrees well with data on age at first attack in the Town of Tecumseh, Mich. It appears that susceptibility does not gradually diminish, but rather disappears abruptly. The calculation yields an estimate of the proportion of children, among those susceptible, who will have at least one attack before they exceed the age of suceptibility. Penetrance of the condition, measured in this way, is nearly complete: 93.8% will have manifested the condition by age 7. The population frequency of the susceptible type of child is found to be 3.90%. If one assumes the simple dominant mode of inheritance of Frantzen et al. to be correct, this estimate of population frequency leads to an estimate of the gene frequency. This is approximately p = 0.02. The homozygote would therefore have a frequency of 4 per 10,000. Some speculations on verifying this theory of inheritance by identifying the homozygote are given. RĂSUMĂ On Ămet une hypothĂse simple sur la survenue des convulsions fĂbriles, Ă savoir (1) que certains enfants sont gĂnĂtiquement prĂdisposĂs et (2) que pour ces enfants la probabilitĂ d'apparition de la premiĂre crise dans la premiĂre, la seconde annĂe, etc. est essentiellement constante jusqu'Ă la fin de la pĂriode pendant laquelle les crises peuvent survenir. De telles suppositions conduisent ĂĂtablir un modĂle de probabilite qui concorde bien avec les donnĂes sur l'Ăge de la premiĂre crise, dans la ville de Techumseh, dans le Michigan. Il en ressort que cette prĂdisposition ne diminue pas progressivement, mais au contraire, disparaĂt brusquement. Les calculs permettent d'estimer la proportion d'enfants prĂdisposĂs qui auront au moins une crise, avant d'avoir dĂpassĂ l'Ăge limite de la prĂdisposition. La pĂnĂtrance de cette condition, ainsi ĂvaluĂe, est presque complĂte: 93.8% des enfants auront manifestĂ cette condition Ă l'Ăge de 7 ans. La frĂquence des enfants prĂdisposĂs dans la population est de 3.90%. Si l'on considĂre que le mode d'hĂrĂditĂ dominante simple de Frantzen est valable, cette estimation de la frĂquence dans la population conduit Ă une Ăvaluation de la frĂquence du gĂne. Celle-ci est approximativement de p = 0.02; l'homozygote aurait done une frĂquence de 4/10.000. Les possibilitĂs de vĂrifier cette thĂorie des modalitĂs hĂrĂditaires par l'identification de l'homozygote sont discutĂes.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/65705/1/j.1528-1157.1972.tb05265.x.pd
Machine-Readable Privacy Certificates for Services
Privacy-aware processing of personal data on the web of services requires
managing a number of issues arising both from the technical and the legal
domain. Several approaches have been proposed to matching privacy requirements
(on the clients side) and privacy guarantees (on the service provider side).
Still, the assurance of effective data protection (when possible) relies on
substantial human effort and exposes organizations to significant
(non-)compliance risks. In this paper we put forward the idea that a privacy
certification scheme producing and managing machine-readable artifacts in the
form of privacy certificates can play an important role towards the solution of
this problem. Digital privacy certificates represent the reasons why a privacy
property holds for a service and describe the privacy measures supporting it.
Also, privacy certificates can be used to automatically select services whose
certificates match the client policies (privacy requirements).
Our proposal relies on an evolution of the conceptual model developed in the
Assert4Soa project and on a certificate format specifically tailored to
represent privacy properties. To validate our approach, we present a worked-out
instance showing how privacy property Retention-based unlinkability can be
certified for a banking financial service.Comment: 20 pages, 6 figure
Effects of the sea lice bath treatment pharmaceuticals hydrogen peroxide, azamethiphos and deltamethrin on egg-carrying shrimp (Pandalus borealis)
This study investigated effects of sea lice pharmaceuticals on egg-bearing deep-water shrimp (Pandalus borealis). Both mortality and sub-lethal effects (behavior, embryo development, and reproductive output) were studied for each of three pharmaceuticals alone and in different sequential combinations. The most severe effect was observed for deltamethrin where 2 h exposure to 330 times diluted treatment dose (alone and in sequential application with hydrogen peroxide and azamethiphos) induced almost 100% mortality within a few days after exposure. Similar effects were not observed for hydrogen peroxide or azamethiphos. However, sequential treatment of hydrogen peroxide and azamethiphos (2 h exposure to each pharmaceutical; 500 times dilution) resulted in >40% mortality during the first week following treatment. No sub-lethal effects or loss of eggs in female shrimp could be related to exposure to the bath treatments. Future studies should investigate potential sub-lethal effects at exposure concentrations close to the no-effect concentration
Combined effects of crude oil exposure and warming on eggs and larvae of an arctic forage fish
Climate change, along with environmental pollution, can act synergistically on an organism to amplify adverse effects of exposure. The Arctic is undergoing profound climatic change and an increase in human activity, resulting in a heightened risk of accidental oil spills. Embryos and larvae of polar cod (Boreogadus saida), a key Arctic forage fish species, were exposed to low levels of crude oil concurrently with a 2.3 °C increase in water temperature. Here we show synergistic adverse effects of increased temperature and crude oil exposure on early life stages documented by an increased prevalence of malformations and mortality in exposed larvae. The combined effects of these stressors were most prevalent in the first feeding larval stages despite embryonic exposure, highlighting potential long-term consequences of exposure for survival, growth, and reproduction. Our findings suggest that a warmer Arctic with greater human activity will adversely impact early life stages of this circumpolar forage fish

The Efficacy of Simulation as a Pedagogy in Facilitating Pre-Service Teachersâ Learning About Emotional Self-Regulation and its Relevance to the Teaching Profession
This study was undertaken in response to the imperative of teacher education courses incorporating National Professional Standards for Teachers, in particular Standard 7, which deals with the professional engagement of teachers (AITSL, 2011). It aimed to evaluate the efficacy of simulation and active recall as a learner-centred pedagogy in facilitating pre-service teachersâ learning about their capacity to self-regulate emotionally and its relevance to the profession. A simulated âcritical incidentâ was used in a lecture to guide students (n=106) to analyse and understand their emotional responses to an altercation between the lecturer and a colleague. The evaluation involved both quantitative and qualitative data collection. The study generated six useful insights associated with the efficacy of simulation pedagogy and revealed convincingly that this pedagogy can engage students actively in learning about the importance of emotional self-regulation in relation to their professional role as a teacher
