Spectral flow invariants and twisted cyclic theory from the Haar state on SU_q(2)

In [CPR2], we presented a K-theoretic approach to finding invariants of algebras with no non-trivial traces. This paper presents a new example that is more typical of the generic situation. This is the case of an algebra that admits only non-faithful traces, namely SU_q(2), and also KMS states. Our main results are index theorems (which calculate spectral flow), one using ordinary cyclic cohomology and the other using twisted cyclic cohomology, where the twisting comes from the generator of the modular group of the Haar state. In contrast to the Cuntz algebras studied in [CPR2], the computations are considerably more complex and interesting, because there are nontrivial `eta' contributions to this index.Comment: 25 pages, 1 figur

A noncommutative framework for topological insulators

We study topological insulators, regarded as physical systems giving rise to topological invariants determined by symmetries both linear and anti-linear. Our perspective is that of noncommutative index theory of operator algebras. In particular we formulate the index problems using Kasparov theory, both complex and real. We show that the periodic table of topological insulators and superconductors can be realised as a real or complex index pairing of a Kasparov module capturing internal symmetries of the Hamiltonian with a spectral triple encoding the geometry of the sample's (possibly noncommutative) Brillouin zone.Comment: 32 pages, final versio

An exploration into the client at the heart of therapy : a qualitative perspective

Over 50 years ago Eysenck challenged the existing base of research into psychotherapy. Since that time, a large number of investigations have been conducted to verify the efficacy of therapy. Recently however, an increasing number of studies have cast new doubts on this research base. Instead of therapy being a function of the therapist, it is now becoming ever more apparent that the client plays a prime role in the therapeutic process. The qualitative studies presented in this paper provide some examples of research that demonstrates that clients are actively involved in their therapy, even making counselling work despite their counsellor. These studies suggest that clients may not experience therapy as beneficially as traditional outcome studies indicate. This raises a new challenge to researchers to more fully explore the client's experience of therapy, a challenge to which qualitative methods of inquiry would appear well suited

Survey of York University 1976-78 Bachelor's Degree Graduates in Psychology Located in Greater Toronto

A survey was made of 325 graduates who obtained a Bachelor's degree in psychology between 1976-78. It was found that (a) 73.5% of the alumni were in the labour force, with the majority working in either parapsychological jobs, teaching, or business management; (bj the average salaries of the men and women were $14,610 and$12,020, respectively; (c) the unemployment rates for men and women were 9.8% and 6.1%; (d/ these rates were elevated by the rates for the 1978 graduates; and (e) 41.8% of the graduates went on to further training. The results are discussed in terms of the relevance of the Bachelor's degree in today's marketplace, and in terms of university programming in undergraduate edu- cation in psychology.Un sondage fut effectué sur 325 diplômé en psychologie ayant reçu leur baccalauréat (B.A.) entre 1976-1978 à York University. Les résultats ont indiqué que (a) 73.5% des diplômés étaient déjà sur le marché du travail où la majorité oeuvraient dans des emplois para-psychologiques, dans l'enseignement ou dans la gestion des affaires; (b) le salaire moyen était de $14,610 pour les hommes et de$12,020 pour les femmes; (cj les taux de chômage étaient de 9.8% et 6.1% respectivement chez les hommes et les femmes; (d) ces taux étaient particulièrement élevés pour les diplômés de l'année 1978; etfej 41.8%des diplômés avaient entrepris une formation subséquente. Une analyse fut également con-duite au sujet de la demande qui existe actuellement sur le marché du travail pour un baccalauréat ainsi qu'à propos du développement des programmes d'études universitaires en psychologie au niveau du premier cycle

Physical activity and hypertension in South African adults

This work is licensed under a Creative Commons Attribution-Noncommercial-No Derivative Works 2.5 South Africa LicenseEstimates suggest that approximately 6-million South Africans have hypertension, with half classified as stage 1 (mild). Mindful of the cost of lifelong drug therapy, the South African Hypertension Society guidelines suggest delaying drug therapy through lifestyle modification (increased physical activity and weight management) in all but those with the highest risk. This pilot study examined the relationship of BP with physical activity and bodyweight in black South African adults employed in physical occupationsNon peer reviewe

Associations between dietary added sugar intake and micronutrient intake: a systematic review

Original article can be found at: http://journals.cambridge.org/ Copyright The Authors. DOI: 10.1017/S0007114507617206There is increasing concern that high intakes of added sugars might compromise intakes of micronutrients. The objectives of this systematic review were (1) to determine whether dietary added sugar intake was associated with micronutrient intakes, and if so, whether there was evidence of micronutrient dilution as a result of higher dietary added sugar intake and (2) if micronutrient dilution was present, to determine whether there was sufficiently robust evidence to support a threshold effect above which there was a significant decline in micronutrient intake or status relative to the recommended intakes. A systematic computerised literature search was undertaken, limited to studies written in English published from 1980 onwards and further studies identified through hand searching papers. Fifteen studies that assessed associations between intakes of added sugars or non-milk extrinsic sugars and micronutrients were included. Overall, there are insufficient data and inconsistency between studies in relationships between added sugars and micronutrient intakes, with no clear evidence of micronutrient dilution or a threshold for a quantitative amount of added sugar intake for any of the micronutrients investigated. The current evidence base is considerably constrained by methodological issues. Further research is required to determine which food products high in added sugars might adversely affect micronutrient intakes by displacing other food items from the diet. Analyses should take into account the magnitude of any observed associations to determine their true biological significance.Peer reviewe
