Ethnic Identity of Older Chinese in Canada

In Canada’s multicultural society, ethnic identity is important to the elderly and can influence areas such as access to services, health promotion and care. Often, the complex nature of ethnic identity is underestimated when looking at cultural groups. This study aims to: (a) validate the factor structure of a Chinese ethnic identity measure for older Chinese in Canada, (b) examine the level of ethnic identity of the participants, and (c) examine the correlates of ethnic identity in these older individuals. Using data from a large, national research project on the elderly Chinese in Canada, this study analyzed the results gathered from a total of 2,272 participants. Principal component analysis, maximum-likelihood confirmatory factor analysis, and multiple regression analysis were performed. The results indicated that ethnic identity of the older Chinese is a multi-dimensional construct made up of three factors: (a) culture related activities, (b) community ties, (c) linkage with country of origin, and (d) cultural identification. The findings have provided a better understanding of how ethnic identity can be measured among the aging Chinese population in Canada

THE FIRST FERMI -LAT CATALOG OF SOURCES ABOVE 10 GeV

We present a catalog of ?-ray sources at energies above 10?GeV based on data from the Large Area Telescope (LAT) accumulated during the first 3?yr of the Fermi Gamma-ray Space Telescope mission. The first Fermi-LAT catalog of >10?GeV sources (1FHL) has 514?sources. For each source we present location, spectrum, a measure of variability, and associations with cataloged sources at other wavelengths. We found that 449 (87%) could be associated with known sources, of which 393 (76% of the 1FHL sources) are active galactic nuclei. Of the 27?sources associated with known pulsars, we find 20 (12) to have significant pulsations in the range >10?GeV (>25?GeV). In this work we also report that, at energies above 10?GeV, unresolved sources account for 27% ? 8% of the isotropic ?-ray background, while the unresolved Galactic population contributes only at the few percent level to the Galactic diffuse background. We also highlight the subset of the 1FHL sources that are best candidates for detection at energies above 50-100?GeV with current and future ground-based ?-ray observatories
