Selected AbstractsUsing the PRISM to Compare the Explanatory Value of General and Role-Contextualized Trait RatingsJOURNAL OF PERSONALITY, Issue 6 2007Dustin Wood ABSTRACT In an earlier work (Wood & Roberts, 2006), the Personality and Role Identity Structural Model (PRISM) was proposed as a model for organizing the relations between diverse self-perceptions, with a person's general identity ("how I am in general") organized above diverse role identities (e.g., "how I am as an employee"), which in turn is organized above role-specific behaviors and experiences (e.g., typical interactions with coworkers). In the present article, I argue that despite the fact that role trait measures are often much more related to role behaviors than general trait measures in cross-sectional analyses, general trait measures better capture the dispositional causes of a person's role behavior. In support of this, a brief study is presented illustrating how general traits may be better predictors than role-contextualized trait ratings of the evolution of an individual's experiences or behaviors within a given context. Finally, I contend that the basic framework of the PRISM, where a person's behaviors and identities within multiple contexts are assessed simultaneously and longitudinally alongside general personality ratings, is necessary to make strong statements concerning the nature of the relationships between personality traits and role experiences. [source] At the Margins of Death: Ritual Space and the Politics of Location in an Indo-Himalayan Border VillageAMERICAN ETHNOLOGIST, Issue 3 2001Ravina Aggarwal I base this article on an event that transpired during a funeral ceremony in the village of Achinathang in Ladakh, India. This incident, which coincided with a period of interreligious conflicts between Muslim and Buddhist communities, led me to question the manner in which margins become sites for the definition and contestation of citizenship and power. Here, I analyze the construction of margins in multiple contexts: in negotiating boundaries between death and rebirth, in coping with and challenging the control exerted by town-based political reform movements over rural space, and finally, in locating the position of the ethnographer in histories and spaces of domination.

Because of the tissue interactions that drive head development, these forebrain defects are typically accompanied by midline deficiencies of craniofacial structures. Early events in setting up tissue precursors of the head, as well as later interactions between these tissues, are critical for normal head formation. Defects in either process can result in HPE. Signaling by bone morphogenetic proteins (BMPs), a family of secreted cytokines, generally plays negative roles in early stages of head formation, and thus must be attenuated in multiple contexts to ensure proper forebrain and craniofacial development. Chordin and Noggin are endogenous, extracellular antagonists of BMP signaling that promote the normal organization of the forebrain and face. Mouse mutants with reduced levels of both factors display mutant phenotypes remarkably analogous to the range of malformations seen in human HPE sequence. Chordin and Noggin function in part by antagonizing the inhibitory effects of BMP signaling on the Sonic hedgehog and Nodal pathways, genetic lesions in each being associated with human HPE. Study of Chordin;Noggin mutant mice is helping us to understand the molecular, cellular, and genetic pathogenesis of HPE and associated malformations. © 2010 Wiley-Liss, Inc. [source] Prospective effects of violence exposure across multiple contexts on early adolescents' internalizing and externalizing problemsTHE JOURNAL OF CHILD PSYCHOLOGY AND PSYCHIATRY AND ALLIED DISCIPLINES, Issue 8 2010Sylvie Mrug Background:, Violence exposure within each setting of community, school, or home has been linked with internalizing and externalizing problems. Although many children experience violence in multiple contexts, the effects of such cross-contextual exposure have not been studied. This study addresses this gap by examining independent and interactive effects of witnessing violence and victimization in the community, home, and school on subsequent internalizing and externalizing problems in early adolescence. Methods:, A community sample of 603 boys and girls (78% African American, 20% Caucasian) participated in a longitudinal study of youth violence. During two assessments 16 months apart, adolescents reported on witnessing violence and victimization in the community, school, and home, and their internalizing and externalizing problems. Results:, Multiple regressions tested the independent and interactive effects of witnessing violence or victimization across contexts on subsequent adjustment, after controlling for initial levels of internalizing and externalizing problems and demographic covariates. Witnessing violence at school predicted anxiety and depression; witnessing at home was related to anxiety and aggression; and witnessing community violence predicted delinquency. Victimization at home was related to subsequent anxiety, depression, and aggression; victimization at school predicted anxiety; and victimization in the community was not independently related to any outcomes. Finally, witnessing violence at home was associated with more anxiety, delinquency, and aggression only if adolescents reported no exposure to community violence. Conclusions:, Violence exposure at home and school had the strongest independent effects on internalizing and externalizing outcomes. Witnessing community violence attenuated the effects of witnessing home violence on anxiety and externalizing problems, perhaps due to desensitization or different norms or expectations regarding violence. However, no comparable attenuation effects were observed for victimization across contexts. [source] Assessment of child problem behaviors by multiple informants: a longitudinal study from preschool to school entryTHE JOURNAL OF CHILD PSYCHOLOGY AND PSYCHIATRY AND ALLIED DISCIPLINES, Issue 10 2007David C.R. Kerr Background:, Children's early problem behavior that manifests in multiple contexts is often more serious and stable. The concurrent and predictive validity of ratings of externalizing and internalizing by four informants was examined at preschool and early school age in an at-risk sample. Methods:, Two hundred forty children were assessed by mothers and fathers (Child Behavior Checklist (CBCL)), and teachers and laboratory examiners (Teacher Report Form (TRF)) at ages 3 and 5 years. Results:, All informants' ratings of externalizing converged on a common factor at ages 3 and 5 that showed strong stability over time (, = .80). All informants' age 3 externalizing ratings significantly predicted the problem factor at age 5; mothers', fathers', and teachers' ratings were independently predictive. Ratings of internalizing (except by examiners at age 3) also converged at both ages; the problem factor showed medium stability (, = .39) over time. Only fathers' ratings of age 3 internalizing predicted the age 5 problem factor. Conclusions:, Findings support the value of multi-informant assessment, uphold calls to include fathers in childhood research, and suggest that examiners provide valid, though non-unique assessment data. Examiner contributions may prove useful in many research contexts. [source] | ||||||||||
