Social interaction differences in regular education classes for a secondary student with multiple disabilities.

Since secondary students with severe disabilities are being included into regular education classes, there is no research proposing the ·best class choices to· enhance social interaction with peers without disabilities

Classical BI: Its Semantics and Proof Theory

We present Classical BI (CBI), a new addition to the family of bunched logics which originates in O'Hearn and Pym's logic of bunched implications BI. CBI differs from existing bunched logics in that its multiplicative connectives behave classically rather than intuitionistically (including in particular a multiplicative version of classical negation). At the semantic level, CBI-formulas have the normal bunched logic reading as declarative statements about resources, but its resource models necessarily feature more structure than those for other bunched logics; principally, they satisfy the requirement that every resource has a unique dual. At the proof-theoretic level, a very natural formalism for CBI is provided by a display calculus \`a la Belnap, which can be seen as a generalisation of the bunched sequent calculus for BI. In this paper we formulate the aforementioned model theory and proof theory for CBI, and prove some fundamental results about the logic, most notably completeness of the proof theory with respect to the semantics.Comment: 42 pages, 8 figure

Gender and authority in British women hymn-writers' use of metre, 1760-1900

This article is part of a cluster that draws material from the recent conference Metre Matters: New Approaches to Prosody, 1780–1914. It comprises an introduction by Jason David Hall and six articles presented at the conference, whose aim was to address renewed scholarly interest in versification and form across the long nineteenth century, as well as some of the methodologies underpinning it. The papers included in the cluster look both to the minutiae of Romantic and Victorian metres and to their cultural intertexts. The conference, hosted by the University of Exeter's Centre for Victorian Studies, was held 3–5 July 2008

Towards a Causal Probabilistic Framework for Prediction, Action-Selection & Explanations for Robot Block-Stacking Tasks

Uncertainties in the real world mean that is impossible for system designers to anticipate and explicitly design for all scenarios that a robot might encounter. Thus, robots designed like this are fragile and fail outside of highly-controlled environments. Causal models provide a principled framework to encode formal knowledge of the causal relationships that govern the robot's interaction with its environment, in addition to probabilistic representations of noise and uncertainty typically encountered by real-world robots. Combined with causal inference, these models permit an autonomous agent to understand, reason about, and explain its environment. In this work, we focus on the problem of a robot block-stacking task due to the fundamental perception and manipulation capabilities it demonstrates, required by many applications including warehouse logistics and domestic human support robotics. We propose a novel causal probabilistic framework to embed a physics simulation capability into a structural causal model to permit robots to perceive and assess the current state of a block-stacking task, reason about the next-best action from placement candidates, and generate post-hoc counterfactual explanations. We provide exemplar next-best action selection results and outline planned experimentation in simulated and real-world robot block-stacking tasks.Comment: 4 pages, 4 figures, camera-ready manuscript, accepted to the "Causality for Robotics: Answering the Question of Why" workshop at the 2023 IEEE/RSJ International Conference on Intelligent Robots and Systems (IROS

The effects of AMPA receptor blockade on resting magnetoencephalography recordings

The ionotropic N-methyl-D-aspartate and α-amino-3-hydroxy-5-methyl-4-isoxazolepropionic acid (AMPA) receptors of the glutamatergic neurotransmitter system are of fundamental importance to healthy brain function. Neuroimaging studies in humans have previously been conducted using various drugs that interact with N-methyl-D-aspartate glutamate receptors, but no such studies have investigated AMPA receptor signalling. The recent approval of perampanel (Fycompa) for use in humans provides a means to specifically study the role of AMPA receptors in the pharmacological basis of neuroimaging signals. Twenty male subjects participated in this placebo-controlled crossover study that consisted of two study days separated by a minimum two-week washout period. On one occasion participants ingested a 6 mg dose of perampanel, and on the other a placebo. Ten minutes of wakeful rest was recorded before and after each dose using magnetoencephalography. Subjective ratings of intoxication were significantly higher following drug than placebo. Cluster-based randomisation testing of sensor-level magnetoencephalography data showed significant drug-induced increases in low frequency power (1–4 Hz, 4–8 Hz, 8–13 Hz, 13–30 Hz), along with a significant decrease in the high gamma range (50–90 Hz). We also observed selective increases in functional connectivity in the alpha and beta bands. The findings are consistent with preclinical work and are similar to the spectral profile of other anti-epileptic drugs

The Social Identity Approach to Leadership: The Case of Alberta

The study of political leadership within the discipline of the political science has recently grown into a large, complex, and insightful literature. However, the extensive number of concepts, theories, and frameworks developed by international leadership scholars have been underutilized when it comes to developing further understanding of political leadership in the Canadian context. This thesis attempts to address this gap by focusing on the process by which individuals are selected to be leaders. I utilizes social psychology and Identity Leadership Theory to theorize that leaders are successful to the extent that are able to cohere with broader group processes by articulating group characteristics, establishing individual prototypicality, and entrenching their policy agenda in pre-existing collective identities and understandings. The study develops and examines a concise causal relationship and hypotheses through a case study of the Albertan provincial context. This comprises analyses of two premiers, William Aberhart and Peter Lougheed, that utilize a set of primary communicative sources to examine the substantive components of their successful leadership appeal. Overall, this thesis’s findings suggest that these leaders were successful despite not meeting the expectations of the analysis’s hypotheses. Consequently, it is concluded that Identity Leadership Theory is not an accurate or useful means by which to understand political leadership in Canada

A Situation Analysis of Ley Pasture Utilisation in the Western Downs and Maranoa Regions of S Queensland, Australia

Previous studies have shown that the uptake of ley pasture systems in S Queensland\u27s grain growing region has been slow when compared with mixed farming systems in S Australia. This is despite their demonstrated benefits to subsequent crops, livestock production and the environment. A survey was conducted that aimed to determine the level of utilisation of ley pastures in the Western Downs and Maranoa regions of S Queensland, and the possible constraints to their adoption, and benefits arising from their use. The survey also aimed to determine the commonly used pasture species, the reasons for their use and their contribution to the livestock component of mixed farms
