“…Moreover, we assume that the noise associated with the sparse sampling of the underlying field can be described by a Poisson statistics. While this sounds a very reasonable approximation, recent work on N -body simulations indicate that the actual shot noise properties might significantly deviate from Poisson statistics [36].…”

We consider the problem of optimal weighting of tracers of structure for the purpose of constraining the non-Gaussianity parameter fNL. We work within the Fisher matrix formalism expanded around fiducial model with fNL = 0 and make several simplifying assumptions. By slicing a general sample into infinitely many samples with different biases, we derive the analytic expression for the relevant Fisher matrix element. We next consider weighting schemes that construct two effective samples from a single sample of tracers with a continuously varying bias. We show that a particularly simple ansatz for weighting functions can recover all information about fNL in the initial sample that is recoverable using a given bias observable and that simple division into two equal samples is considerably suboptimal when sampling of modes is good, but only marginally suboptimal in the limit where Poisson errors dominate.PACS numbers: 98.80.Jk, 98.80.Cq

“…In order to derive lower limits on the neutrino mass from those already calculated in [43] for the case of pure WDM (f s = 1), we adopt the following rescaling procedure [76]. For a model with a WDM fraction f s < 1, we find the value of the neutrino mass that produces a suppression of the 1D power spectrum at the fiducial pivot wavenumber k f = 2h Mpc −1 equal to that one obtained (for a larger value of the mass) in the case f s = 1.…”

Sterile neutrinos as subdominant warm dark matter

In light of recent findings which seem to disfavor a scenario with (warm) dark matter entirely constituted of sterile neutrinos produced via the Dodelson-Widrow (DW) mechanism, we investigate the constraints attainable for this mechanism by relaxing the usual hypothesis that the relic neutrino abundance must necessarily account for all of the dark matter. We first study how to reinterpret the limits attainable from X-ray non-detection and Lyman-alpha forest measurements in the case that sterile neutrinos constitute only a fraction fs of the total amount of dark matter. Then, assuming that sterile neutrinos are generated in the early universe solely through the DW mechanism, we show how the X-ray and Lyman-alpha results jointly constrain the mass-mixing parameters governing their production. Furthermore, we show how the same data allow us to set a robust upper limit fs < 0.7 at the 2 sigma level, rejecting the case of dominant dark matter (fs = 1) at the ~ 3 sigma level.Comment: Minor changes; added references; version accepted for publication in Phys.

“…Another contextual influence that may have contributed to lower Quebec levels of association membership is the relatively more statist nature of that province's political and social structure~Baum, 2000; Christian and Campbell, 1983: 36;Grabb and Curtis, 2005: 171-72;Seljak, 2000: 145!. We should remark that, despite suggestions that the "social welfare" orientation of statist democracies discourages individual citizens from participating in voluntary associations~Drucker, 1994; Lipset, 1990: 148; 277!, research generally shows that more statist or social democratic nations-Sweden, the Netherlands, Norway and so forth-typically equal or exceed liberal democracies in active association involvement Andersen et al, 2006;Curtis et al, 1992Curtis et al, , 2001!.…”

Voluntary Association Activity in Quebec and English Canada: Assessing the Effects of Region and Language

2007

Abstract.This paper presents the first multivariate analysis of the combined effects of region and language on voluntary association membership in Canada. National survey data from 2000 indicate that Quebecers have the lowest average number of memberships, with Western Canadians highest and Atlantic and Ontario residents in between. Preliminary results also confirm that francophones report fewer memberships than anglophones. Findings from Poisson regression models, however, indicate a significant interaction between region and language: francophones have lower membership levels only in Quebec, and in Western Canada have higher levels than anglophones or allophones. These results hold even with controls for a number of possible explanatory factors suggested in the literature, including religious and socioeconomic differences across the regions and language groups. The implications for understanding patterns of voluntary association activity in Canada are discussed.Résumé.Cet article présente la première analyse multivariable des effets combinés de la région et de la langue sur l'adhésion d'aux associations volontaires au Canada. Les données nationales de 2000 indiquent que les Québécois ont le plus bas nombre moyen d'adhésions, avec les Canadiens de l'Ouest plus hauts et des résidants de la région atlantique et de l'Ontario entre les deux. Les résultats préliminaires confirment que les francophones ont moins d'adhésions que les anglophones. Les résultats indiquent une interaction significative entre la région et la langue: les francophones ont moins d'adhésion seulement au Québec; dans le Canada de l'Ouest les francophones ont plus d'adhésion que les anglophones et les allophones. Ces résultats se tiennent même avec contrôle d'un certain nombre de facteurs explicatifs possibles suggérés dans la littérature, y compris des différences religieuses et socio-économiques à travers les régions et les groupes linguistic. Nous discutons les implications quant aux modèles d'association volontaire au Canada.
