Are good jobs disappearing in Canada?

Based on their analysis of changes in the share of jobs falling in certain real wage categories over 1997-2004, the authors suggest that well-paid jobs ($25 an hour or more) are not disappearing in Canada. Morissette and Johnson also find little evidence that the relative importance of well-paid jobs has declined or that the relative importance of low-paid jobs (less than$10 hour) has risen over the past two decades.Labor market - Canada ; Business cycles - Canada ; Economic conditions - Canada

Analyse intersectionnelle de la solidarité des intérêts au World Congress of Representative Women (Chicago, 1893)

Dans cet article, nous situons le World Congress of Representative Women tenu à Chicago en 1893, première rencontre internationale de grande envergure organisée par et pour des femmes représentant diverses nations et divers groupes de femmes dans son contexte historique, celui de l’exposition universelle colombienne organisée par une Amérique en pleine expansion impérialiste. À l’aide d’un cadre d’analyse féministe intersectionnelle, nous analysons les intersections entre divers rapports de pouvoir en jeu lors de cet événement et nous illustrons certaines limites de la solidarité internationale lors de la constitution des premiers réseaux internationaux de groupes de femmes. En conclusion, nous nous interrogeons sur les pratiques actuelles de certains réseaux transnationaux de femmes en présence aux Nations Unies.The World Congress of Representative Women was held in Chicago in 1893. It was the first large-scale international gathering organised by and for women representing many countries and a wide variety of women’s groups. This article analyses the event in its historical context, that of a world peace exhibition organised by a United States characterised by rising imperialism. Using a feminist and intersectional framework, this article examines the intersection of the various power relations in play at this event and documents some of the limits to international solidarity evident when the first international women’s networks were being constituted. The conclusion raises questions about the practices of some contemporary transnational women’s networks at the United Nations

An elementary construction of Anick's fibration

Cohen, Moore, and Neisendorfer's work on the odd primary homotopy theory of spheres and Moore spaces, as well as the first author's work on the secondary suspension, predicted the existence of a p-local fibration S^2n-1 --> T --> \Omega S^2n+1 whose connecting map is degree p^r. In a long and complex monograph, Anick constructed such a fibration for p>= 5 and r>= 1. Using new methods we give a much more conceptual construction which is also valid for p=3 and r>= 1. We go on to establish several properties of the space T.Comment: 30 page

High Sensitivity 1H-NMR Spectroscopy of Homeopathic Remedies Made in Water

Background: The efficacy of homeopathy is controversial. Homeopathic remedies are made via iterated shaking and dilution, in ethanol or in water, from a starting substance. Remedies of potency 12 C or higher are ultra-dilute (UD), i.e. contain zero molecules of the starting material. Various hypotheses have been advanced to explain how a UD remedy might be different from unprepared solvent. One such hypothesis posits that a remedy contains stable clusters, i.e. localized regions where one or more hydrogen bonds remain fixed on a long time scale. High sensitivity proton nuclear magnetic resonance spectroscopy has not previously been used to look for evidence of differences between UD remedies and controls. Methods: Homeopathic remedies made in water were studied via high sensitivity proton nuclear magnetic resonance spectroscopy. A total of 57 remedy samples representing six starting materials and spanning a variety of potencies from 6 C to 10 M were tested along with 46 controls. Results: By presaturating on the water peak, signals could be reliably detected that represented H-containing species at concentrations as low as 5 μM. There were 35 positions where a discrete signal was seen in one or more of the 103 spectra, which should theoretically have been absent from the spectrum of pure water. Of these 35, fifteen were identified as machine-generated artifacts, eight were identified as trace levels of organic contaminants, and twelve were unexplained. Of the unexplained signals, six were seen in just one spectrum each. None of the artifacts or unexplained signals occurred more frequently in remedies than in controls, using a p < .05 cutoff. Some commercially prepared samples were found to contain traces of one or more of these small organic molecules: ethanol, acetate, formate, methanol, and acetone. Conclusion: No discrete signals suggesting a difference between remedies and controls were seen, via high sensitivity 1H-NMR spectroscopy. The results failed to support a hypothesis that remedies made in water contain long-lived non-dynamic alterations of the H-bonding pattern of the solvent

How do extreme global shocks affect foreign portfolio investment? An event study for India

Foreign portfolio flows in and out of India are relevant for policymakers, and are often portrayed in the media as having a destabilizing effect on the domestic market. We use an event study approach to examine whether extreme global shocks trigger abnormal responses in foreign equity flows in and out of India, or abnormal responses in the Indian stock market. We do not find strong evidence of abnormal responses, even for the case of the global crisis of 2008

Golod-Shafarevich algebras, free subalgebras and Noetherian images

It is shown that Golod-Shaferevich algebras of a reduced number of defining relations contain noncommutative free subalgebras in two generators, and that these algebras can be homomorphically mapped onto prime, Noetherian algebras with linear growth. It is also shown that Golod-Shafarevich algebras of a reduced number of relations cannot be nil
