Precision electroweak measurements on the Z resonance
We report on the final electroweak measurements performed with data taken at the Z resonance by the experiments operating at the electron-positron colliders SLC and LEP. The data consist of 17 million Z decays accumulated by the ALEPH, DELPHI, L3 and OPAL experiments at LEP, and 600 thousand Z decays by the SLD experiment using a polarised beam at SLC. The measurements include cross-sections, forward-backward asymmetries and polarised asymmetries. The mass and width of the Z boson, $\MZ$ and $\GZ$, and its couplings to fermions, for example the $\rho$ parameter and the effective electroweak mixing angle, are precisely measured. The number of light neutrino species is determined to be 2.9840…
Parental warmth and socio-emotional adjustment in Brazilian, Canadian, Chinese and Italian children: A cross-cultural perspective
The primary purpose of the study was to investigate the role of cultural context in shaping parental warmth and its linkages with children’s socio-emotional adjustment in Brazilian, Canadian, Chinese and Italian children. We were interested in several specific issues including (1) whether there were cross-cultural differences in parental warmth among the samples, and (2) whether the relations between parental acceptance-rejection and child outcomes were similar across cultures. In addition, we were interested in whether children perceived mothers and fathers differently with respect to the provision of warmth, and whether maternal warmth and paternal warmth made differential contributions t…
