Strategic Policy Issues for Agricultural Research in Canada
Agricultural research has been a very important factor in enhancing the productivity and competitiveness of the Canadian agri-food sector. Science and innovation have been identified as together forming one of the five pillars in the Canadian Agri-food Policy Framework (APF). A major focus of the science and innovation section of the APF is to plan to realign public and private research efforts into a more comprehensive strategic approach for research and innovation in Canada. Despite the importance of research and the need for a strategic approach, however, assessment of critical strategic research policy issues for the Canadian agri-food sector has been limited.Agricultural and Food Policy, Research and Development/Tech Change/Emerging Technologies,

Platelet deposition studies on copolyether urethanes modified with poly(ethylene oxide)
Pellethane ® 2363 80A films and tubings were chemically modified and the effect of these modifications on platelet deposition was studied. Grafting of high molecular weight poly(ethylene oxide) and graft polymerization of methoxy poly(ethylene glycol) 400 methacrylate resulted in surfaces with a good water wettability. The increased hydrophilicity of these modified surfaces could be demonstrated by contact angle measurements. The platelet deposition was investigated with tubings in a capillary flow system, using different types of perfusates. Platelet deposition from a buffer-containing perfusate on surfaces modified with either high molecular weight poly(ethylene oxide) or methoxy poly(ethylene glycol) 400 methacrylate was almost absent and less than on Pellethane 2363 80A. Using a citrated plasmacontaining perfusate the amount of deposited platelets on Pellethane 2363 80A modified with high molecular weight poly(ethylene oxide) was low and about the same as on unmodified surfaces. However, a marked reduced platelet deposition compared to unmodified Pellethane 2363 80A was found when the platelets were activated by Ca2+ ionophore. The improved blood compatibility of the modified Pellethane 2363 80A tubings obviously indicates the favourable effect of the presence of grafted PEO on the surface
Feelin\u27 blue, oh what to do? : coping with negative emotions
Over the past five years I have had the opportunity to work with children and youth, ages birth to eighteen, in a variety of environments. The settings in which I have interacted with children include nonprofit agency environments, after school programs, church environments, parks and recreation programs, individual and small group counseling sessions, classroom guidance settings, and home environments. My own observations and experiences along with those of parents, school staff, university faculty, fellow undergraduate and graduate students, and co-workers have supported my conclusion that children from early childhood to high school youth struggle with knowing how to appropriately respond to negative feelings. Anger outbursts are a common occurrence with the children and youth I have encountered. Countless children I have worked with also fail to appropriately deal with disappointment. Many children grow up in homes where negative feelings are neglected or denied. The purpose of this curriculum is to give children a lens through which to recognize negative emotions, a language to articulate their feelings, and strategies, skills, and tools to cope with their negative feelings in healthy ways
Geometric dependence of Nb-BiTe-Nb topological Josephson junction transport parameters
Superconductor-topological insulator-superconductor Josephson junctions have
been fabricated in order to study the width dependence of the critical current,
normal state resistance and flux periodicity of the critical current modulation
in an external field. Previous literature reports suggest anomalous scaling in
topological junctions due to the presence of Majorana bound states. However,
for most realised devices, one would expect that trivial -periodic
Andreev levels dominate transport. We also observe anomalous scaling behaviour
of junction parameters, but the scaling can be well explained by mere geometric
effects, such as the parallel bulk conductivity shunt and flux focusing
Experimental realization of SQUIDs with topological insulator junctions
We demonstrate topological insulator (BiTe) dc SQUIDs, based on
superconducting Nb leads coupled to nano-fabricated Nb-BiTe-Nb
Josephson junctions. The high reproducibility and controllability of the
fabrication process allows the creation of dc SQUIDs with parameters that are
in agreement with design values. Clear critical current modulation of both the
junctions and the SQUID with applied magnetic fields have been observed. We
show that the SQUIDs have a periodicity in the voltage-flux characteristic of
, of relevance to the ongoing pursuit of realizing interferometers for
the detection of Majorana fermions in superconductor- topological insulator

MIREOT: the Minimum Information to Reference an External Ontology Term
While the Web Ontology Language (OWL) provides a mechanism to import ontologies, this mechanism is not always suitable. First, given the current state of editing tools and the issues they have working with large ontologies, direct OWL imports have sometimes proven impractical for day-to-day development. Second, ontologies chosen for integration may be under active development and not aligned with the chosen design principles. Importing heterogeneous ontologies in their entirety may lead to inconsistencies or unintended inferences. In this paper we propose a set of guidelines for importing required terms from an external resource into a target ontology. We describe the guidelines, their implementation, present some examples of application, and outline future work and extensions
