The Canadian Cluster Comparison Project: weak lensing masses and SZ scaling relations†

Abstract: The Canadian Cluster Comparison Project is a comprehensive multi-wavelength survey targeting 50 massive X-ray selected clusters of galaxies to examine baryonic tracers of cluster mass and to probe the cluster-to-cluster variation in the thermal properties of the hot intracluster medium. In this paper we present the weak lensing masses, based on the analysis of deep wide-field imaging data obtained using the CanadaFrance-Hawaii-Telescope. The final sample includes two additional clusters that were located in the field-of-view. We take these masses as our reference for the comparison of cluster properties at other wavelengths. In this paper we limit the comparison to published measurements of the Sunyaev-Zel’dovich effect. We find that this signal correlates well with the projected lensing mass, with an intrinsic scatter of 12±5% at � r2500, demonstrating it is an excellent proxy for cluster mass.

Bosnian Refugees and the Stressors of Exile: A Narrative Study

Abstract: The authors used semistructured interviews to examine exile-related stressors affecting a sample of 28 adult Bosnian refugees in Chicago. The interviews covered 3 areas: life in prewar Bosnia, the journey of exile, and, most centrally, life in Chicago. Primary sources of exile-related distress included social isolation and the loss of community, separation from family members, the loss of important life projects, a lack of environmental mastery, poverty and related stressors such as inadequate housing, and the loss of valued social roles. The implications of these findings for mental health interventions with refugees are considered, and the value of narrative methods in research with refugee communities is discussed.

The role of locomotion in psychological development.

Abstract: The psychological revolution that follows the onset of independent locomotion in the latter half of the infant's first year provides one of the best illustrations of the intimate connection between action and psychological processes. In this paper, we document some of the dramatic changes in perception-action coupling, spatial cognition, memory, and social and emotional development that follow the acquisition of independent locomotion. We highlight the range of converging research operations that have been used to examine the relation between locomotor experience and psychological development, and we describe recent attempts to uncover the processes that underlie this relation. Finally, we address three important questions about the relation that have received scant attention in the research literature. These questions include: (1) What changes in the brain occur when infants acquire experience with locomotion? (2) What role does locomotion play in the maintenance of psychological function? (3) What implications do motor disabilities have for psychological development? Seeking the answers to these questions can provide rich insights into the relation between action and psychological processes and the general processes that underlie human development.
