Identity development and perceived parental behavior as sources of adolescent egocentrism

Adolescent egocentrism involves heightened self-consciousness and feelings of uniqueness (O. Elkind [1967], Egocentrism in Adolescence, Child Development, Vol. 38, pp. 1025–1034). Some studies have found that adolescent egocentrism is associated with identity development, and other studies have found that egocentrism is associated with perceptions of parental behavior. The purposes of this investigation were to simultaneously examine the associations between these variables (1) to determine whether identity development and perceived parental behavior display separate or overlapping associations with adolescent egocentrism, and (2) to clarify the directions of the relationships between these variables. Four hundred eighteen subjects from 12 to 21 years of age completed established measures of identity development, perceived parental behavior, and egocentrism. Identity development was more strongly and consistently related to egocentrism (egocentric adolescents tended to be identity achieved or to be experiencing an identity crisis), whereas perceived parental behavior accounted for little additional variance. The results also clarify differences between the two primary measures of adolescent egocentrism (the Adolescent Egocentrism Scale and Imaginary Audience Scale).Received his M.Sc. and Ph.D. from the University of Victoria.

Rethinking the admissibility of medical treatises as evidence.

This Article examines the issues and questions which underlie the debate over the admission of "medical treatises" into evidence. The admissibility of this type of evidence is at issue most often in litigation involving complex medico-legal issues. This article outlines the evidentiary basis for admission of medical treatises and discusses the quality of medical treatises in an effort to determine what value to the fact-finder these treatises actually hold. The authors contend that there is an inherent untrustworthiness associated with medical treatises, but do not go so far as to suggest that medical treatises should never be admitted. The Article concludes that there is a need for greater caution in determining admissibility and recommends safeguards to better guarantee trustworthiness and reliability.     

Ultimate Legality: Reading the Community of Law

This article is a contribution to the occasional series dealing with a major book that has influenced the author. Previous contributors include Stewart Macaulay, John Griffith, William Twining, Carol Harlow, Geoffrey Bindman, Harry Arthurs, André-Jean Arnaud, Alan Hunt, Michael Adler, Lawrence O. Gostin, John P. Heinz, Roger Brownsword, Roger Cotterrell, Nicola Lacey, Carol J. Greenhouse, and David Garland. An initial twist: several acute observers would consider the way I read to be the most influential effect of reading on me – a way of reading that extends beyond the specificity of the text yet, in so doing, connects integrally with it. Salvation of specificity is at hand, however. That way of reading is intimately reflective of Derridean deconstruction and a hugely influential reading becomes his ‘Force of Law’. A problem ensues. Other influential reading came before my love of Derrida – influential reading to do with law and society (of course), with decolonization and imperialism, with engaged anthropology, and with critical legal studies. A retrospective revelation then follows. Derridean deconstruction is found to haunt and inform these other readings. They can be read in a way that inherently anticipates deconstruction. Some culminating coherence is offered by the inescapable insistence of community and the mutually intrinsic fusion of community and law.     

Estimating Individual Contributions to Complex DNA SNP Mixtures.,

High‐throughput sequencing (HTS) of large panels of single nucleotide polymorphisms (SNPs) provides an alternative or complimentary approach to short tandem repeats (STRs) panels for the analysis of complex DNA mixture forensic samples. For STRs, methods to estimate individual contribution concentrations compare capillary electrophoresis peak heights, peak areas, or HTS allele read counts within a mixture. This article introduces three approaches (mean, median, and slope methods) for estimating individual DNA contributions to forensic mixtures for HTS/massively parallel sequencing (MPS) SNP panels. For SNPs, the major:minor allele ratios or counts, unique to each contributor, were compared to estimate contributor proportion within the mixture using the mean, median, and slope intercept for these alleles. The estimates for these three methods were typically within 5% of planned experimental contributions for defined mixtures.     

Identity development and formal operations as sources of adolescent egocentrism

The self-concerns and social expectations that are part of the identity development process may lead adolescents to think that others survey them for signs of individuality. The novelty of identity development may also lead to feelings of uniqueness and invulnerability. The imaginary audience and personal fable may therefore stem from identity development and not from the emergence of formal operations. In this study high school and first-year university students (N=255) completed measures of adolescent egocentrism, identity development, and formal operations. Egocentrism was moderately associated with higher scores on identity crisis and identity achievement, and with lower scores on identity diffusion. There was no significant relationship between egocentrism and the emergence of formal operations.Received his M.Sc. and Ph.D. from the University of Victoria.
