Electronic Structure and Valence Band Spectra of Bi4Ti3O12

The x-ray photoelectron valence band spectrum and x-ray emission valence-band spectra (Ti K _beta_5, Ti L_alpha, O K_alpha) of Bi4Ti3O12 are presented (analyzed in the common energy scale) and interpreted on the basis of a band-structure calculation for an idealized I4/mmm structure of this material.Comment: 6 pages + 7 PostScript figures, RevTex3.0, to be published in Phys.Rev.B52 (Oct.95).

X-Ray Photoemission Spectra of Dy(Co1−x\text{}_{1-x}Alx\text{}_{x})2\text{}_{2} Systems

The electronic structure of Dy(Co$\text{}_{1-x}$Al$\text{}_{x}$)$\text{}_{2}$ compounds (Laves phase - MgCu$\text{}_{2}$, C15) for Al concentrations x = 0.0, 0.1, 0.2 was investigated by X-ray photoelectron spectroscopy. The results were compared with the ab initio band structure calculations

Suicidal behaviours in adolescents in Nova Scotia, Canada: protective associations with measures of social capital

Few studies of adolescent suicidality have examined its associations with social capital. We explored associations of measures of individual level social capital with self-reported suicide ideation and suicide attempt in adolescents in Cape Breton, Nova Scotia, Canada, controlling for other factors known to be associated with adolescent suicidality
