The Hopf Rings for KO and KU

We compute the mod two homology Hopf rings of the spectra KO and KU. The spaces in these spectra are the infinite classical groups and their coset spaces, and their homology was first calculated in the Cartan seminars, but the Hopf ring structure was first determined in the second author's unpublished PhD thesis. The presentation given here serves as an introduction to the first author's much more intricate work on the connective spectrum bo. The Hopf ring viewpoint turns out to be very convenient for understanding the homological effect of various maps between classical groups and fibrations of their connective covers.Comment: 20 pages; to appear in JPA

L’importance des processus cognitifs et de la recherche empirique en études cinématographiques

Dans la mesure où toute théorie du cinéma compose, implicitement ou explicitement, avec le rôle du spectateur, l'auteur avance qu'il faut postuler l'activité de processus psychologiques - conscients ou inconscients - qui se révèlent finalement d'ordre cognitif. Il fait notamment valoir que ceux qui critiquent la théorie cognitive du cinéma semblent parfois ne pas comprendre ou ne pas connaître les courants qui caractérisent actuellement la psychologie cognitive et la cognition sociale. Présentant un éventail de recherches expérimentales récentes, dont plusieurs sont menées au laboratoire qu'il dirige, l'auteur montre comment l'empirisme permet d'expliciter plusieurs notions introduites en études cinématographiques par Bordwell. Mais surtout, les données qu'il présente font la preuve que la recherche empirique peut contribuer pour beaucoup au développement de la théorie du cinéma.Since all film theories are implicitly or explicitly concerned with spectatorship, the author proposes that this requires postulating the activity of conscious and unconscious psychological processes that are ultimately "cognitive" in nature. He then puts forward that criticism of cognitive film theory often stems from a misunderstanding or lack of knowledge about current trends in cognitive and social-cognitive psychology. A brief survey of research that is pertinent to several of Bordwell's ideas includes experiments conducted in the authors laboratory and demonstrates the contribution that empirical studies can make to film theory, especially with regard to the importance of narrative structure, the relations between cognition and emotions and the role of cognitive biases in film interpretation by both spectators and critics

Massage Therapy in Outpatient Cancer Care: A Metropolitan Area Analysis.

Massage offers cancer patients general quality of life benefits as well as alleviation of cancer-related symptoms/cancer-treatment-related symptoms including pain, anxiety, and fatigue. Little is known about whether massage is accessible to cancer patients who receive treatment in the outpatient setting and how massage is incorporated into the overall cancer treatment plan. Outpatient cancer centers (n = 78) in a single metropolitan area were included this mixed-methods project that included a systematic analysis of website information and a telephone survey. Massage was offered at only 40 centers (51.3% of total). A range of massage modalities were represented, with energy-based therapies (Reiki and Therapeutic Touch) most frequently provided. Although massage therapists are licensed health care providers in the states included in this analysis, massage was also provided by nurses, physical therapists, and other health care professionals

Pallet Racking Using Cold-reduced Steel

Codes of practice for the design of cold-formed sections have generally included a requirement for the coil material to possess a specified amount of ductility prior to forming. The scientific basis for such ductility requirements is shrouded in historical mystery but code drafting committees have been reluctant to remove these requirements in the absence of good reason. However, very low ductility steels have been used for the manufacture of cold-formed steel components for many years by the two leading UK manufacturers of storage racks without this lack of ductility giving rise to any problems during either manufacture or service. This relatively hard material is produced by taking conventional coil material and cold-reducing it prior to forming it into beam, column and other components. The advantage gained by this procedure is a significant increase in the yield stress but the penalty is a considerable reduction in the ductility. As, up to the present time, storage racking has not been subject to formal approval procedures, the absence of clauses in UK or European Codes of Practice allowing the use of these hard steels has not caused any problems. However, this situation is now changing and it has become necessary to justify their performance in comparison with material of more usual ductility. It may be noted here that the use of low ductility steel is not unique to storage racking because very hard steels have been also used successfully in Europe for the manufacture of profiled steel cladding. Galvanised coil is available with a guaranteed yield stress of 550 N/mm² and several manufacturers successfully form this material. Indeed, the first author has tested roof sheeting made from material which had a measured yield stress in excess of 700 N/mm² together with zero elongation in a conventional tensile test. The buckling-yielding failure modes observed in both single and two-span tests to failure showed no evidence of the influence of reduced ductility. In this paper, the justification for the use of low-yield stress steel is taken a stage further by describing a series of tests on racking components made from both cold-reduced steel and an equivalent hot-rolled steel of similar yield stress but much greater ductility. It is shown that the use of hard steel has no adverse effect on performance. The paper concludes by describing a test to failure of a full scale rack structure fabricated using components made from cold-reduced steel

Noradrenaline effects on social behaviour, intergroup relations, and moral decisions

Recent research has begun to elucidate the neural basis of higher order social concepts, such as the mechanisms involved in intergroup relations, and moral judgments. Most theories have concentrated on higher order emotions, such as guilt, shame, or empathy, as core mechanisms. Accordingly, psychopharmacological and neurobiological studies have investigated the effects of manipulating serotonin or oxytocin activity on moral and social decisions and attitudes. However, recently it has been determined that changes in more basic emotions, such as fear and anger, might also have a significant role in social and moral cognition. This article summarizes psychopharmacological and fMRI research on the role of noradrenaline in higher order social cognition suggesting that indeed noradrenergic mediated affective changes might play key – and probably causal – role in certain social attitudes and moral judgments. Social judgments may also be directly influenced by numerous neurotransmitter manipulations but these effects could be mediated by modulation of basic emotions which appear to play an essential role in the formation of social concepts and moral behaviour
