This paper discusses the role of context and ontologies in educational process modeling. Educational process modeling seeks to represent the complex interactions that take place in multi-actor learning environments, with ...

Four secondary enrichment protocols (conventional methods: UVM II, Fraser 24 h and Fraser 48 h: Impedimetric method: Listeria electrical detection medium) were studied for their ability to isolate Listeria spp. and Listeria monocytogenes from fish and environmental samples collected along the processing chain of cold-smoked fish. From all methods, Listeria spp. and L. monocytogenes were respect...

The present work concerns the second order ancillary determined by the tangent directions V = ∂y/∂θ|{y0; θ̂(y0)} at the observed data y 0 for fixed pivotal value, by using the structural approach of Fraser (1986). We show that for scalar parameter case, such an approximate ancillary is well defined and can be described as a rotation. These second order ancillaries are particularly useful in prov...

BACKGROUND Nursing homes provide long-term housing, support and nursing care to frail elders who are no longer able to function independently. Although studies conducted in the United States have demonstrated an association between for-profit ownership and inferior quality, relatively few Canadian studies have made performance comparisons with reference to type of ownership. Complaints are one ...

The “separable” uncertainty sets have beenwidely used in robust portfolio selection models [e.g., see Erdoğan et al. (Robust portfolio management. manuscript, Department of Industrial Engineering and Operations Research, Columbia University, New York, 2004), Goldfarb and Iyengar (Math Oper Res 28:1–38, 2003), Tütüncü and Koenig (Ann Oper Res 132:157–187, 2004)]. For these uncertainty sets, each...
