We have searched for two-body charmless decays of B mesons to purely hadronic exclusive final states including ω or φ mesons using data collected with the CLEO II detector. With this sample of 6.6 × 106 B mesons we observe a signal for the ωK+ final state, and measure a branching fraction of B(B+ → ωK+) = (1.5 −0.6 ± 0.2) × 10−5. We also observe some evidence for the φK final state, and upper l...
This study examined how classroom management practices—care and behavioral control—were differentially associated with students’ engagement, misbehavior, and satisfaction with school, using a large representative sample of 3196 Grade 9 students from 117 classes in Singapore. Results of hierarchical linear modeling showed differential relations. After controlling for students’ gender and socioec...
According to the World Health Organization(WHO), the directing and coordinating authority for health within the United Nations system http://www.who.int/ cancer/en/, from a total of 58 million deaths in 2005, cancer accounts for 7.6 million (or 13%) of all deaths worldwide. This places cancer as one of the leading causes of death in the world, with lung cancer (the main cancer leading to mortal...
Middle school mathematics teachers are often forced to choose between assisting students’ development and assessing students’ abilities because of limited classroom time available. To help teachers make better use of their time, a web-based system, called the Assistment system, was created to integrate assistance and assessment by offering instruction to students while providing a more detailed...
The main subject of this paper is to describe an experiment of blending two domains using our previous work, Blender (Pereira and Cardoso, 2001), a computational attempt to model Fauconnier and Turner’s (98) Conceptual Blending. In this experiment, we visualize the resulting instances using a logo-like language, allowing us to produce visual blends. We discuss the results and suggest further im...
Introduction Biochar is a solid material obtained from the thermochemical conversion of biomass in an oxygen-limited environment. Biochar can be used as a product itself or as an ingredient within a blended product, with a range of applications as an agent for soil improvement, improved resource use efficiency, remediation and/or protection against particular environmental pollution, and as an ...
This paper presents a series of simulation experiments related to the interaction of memory and analogy-making in the AMBR model. This interaction makes it possible to demonstrate blending between superficially dissimilar episodes as a result of the established analogical mapping between them and of superficially and structurally dissimilar episodes as a result of a double analogy with a third ...
The millennia-old practices of horse training markedly predate and thus were isolated from the midtwentieth century revelation of animal learning processes. From this standpoint, the progress made in the application and understanding of learning theory in horse training is reviewed including a discussion of how learning processes are employed or otherwise under-utilised in training. This review...
Blending is both the strength and the weakness of functionally based implicit surfaces (such as F-reps or softobjects). While it gives them the unique ability to smoothly merge into a single, arbitrary shape, it makes implicit modelling hard to control since implicit surfaces blend at a distance, in a way that heavily depends on the slope of the field functions that define them. This paper pres...
