'Plainly of considerable moment in human society': Francis Hutcheson and polite laughter in eighteenth-century Britain and Ireland

This article focuses on Francis Hutcheson's Reflections Upon Laughter, which was originally published in 1725 as a series of three letters to The Dublin Journal during his time in the city. Although rarely considered a significant example of Hutcheson's published work, Reflections Upon Laughter has long been recognised in the philosophy of laughter as a foundational contribution to the ‘incongruity theory’ – one of the ‘big three’ theories of laughter, and that which is still considered the most credible by modern theorists. The article gives an account of Hutcheson's text but, rather than evaluating it solely as an explanation of laughter, the approach taken is an historical one: it emphasises the need to reconnect the theory to the cultural and intellectual contexts in which it was published and to identify the significance of Hutcheson's arguments in time and place. Through this, the article argues that Hutcheson's theory of laughter is indicative of the perceived significance of human risibility in early eighteenth-century Britain and Ireland and, more broadly, that it contributed both to moral philosophical debate and polite conduct guidance

Parton distribution function for quarks in an s-channel approach

We use an s-channel picture of hard hadronic collisions to investigate the parton distribution function for quarks at small momentum fraction x, which corresponds to very high energy scattering. We study the renormalized quark distribution at one loop in this approach. In the high-energy picture, the quark distribution function is expressed in terms of a Wilson-line correlator that represents the cross section for a color dipole to scatter from the proton. We model this Wilson-line correlator in a saturation model. We relate this representation of the quark distribution function to the corresponding representation of the structure function F_T(x,Q^2) for deeply inelastic scattering

Objective Classes for Micro-Facial Expression Recognition

Micro-expressions are brief spontaneous facial expressions that appear on a face when a person conceals an emotion, making them different to normal facial expressions in subtlety and duration. Currently, emotion classes within the CASME II dataset are based on Action Units and self-reports, creating conflicts during machine learning training. We will show that classifying expressions using Action Units, instead of predicted emotion, removes the potential bias of human reporting. The proposed classes are tested using LBP-TOP, HOOF and HOG 3D feature descriptors. The experiments are evaluated on two benchmark FACS coded datasets: CASME II and SAMM. The best result achieves 86.35\% accuracy when classifying the proposed 5 classes on CASME II using HOG 3D, outperforming the result of the state-of-the-art 5-class emotional-based classification in CASME II. Results indicate that classification based on Action Units provides an objective method to improve micro-expression recognition.Comment: 11 pages, 4 figures and 5 tables.

Effectiveness of staff training programs for behavioral problems among older people with dementia

This paper reviewed studies on staff training programs to address the behavioral problems associated with dementia among older people in residential care. The papers were classified according to whether or not the studies included a control group in the research design. The results of the review demonstrate that there has been a wide range of psychosocial and educational interventions to reduce behavioral problems among older people with dementia, with inconsistent results being obtained. However, many of these studies suffer from problems in their research design that make it difficult to evaluate their effectiveness. Problems in conducting research in the nursing home setting are highlighted, and suggestions for future research in this area are discussed.<br /
