Collective self-esteem consequences of outgroup derogation when a valued social identity is on trial

Abstract: A structural equation model tested the role of degree of identification with a group (Americans) and level of collective self-esteem as determinants of outgroup derogation under identity-threatening and non-threatening conditions. High identification and reductions in collective self-esteem following a threat to that identity lead to outgroup derogation, but level of collective self-esteem did not predict outgroup derogation in the no-threat condition. The consequences of derogating both threat-relevant (Russians) and threat-irrelevant nationalities for subsequent self-esteem were assessed. As predicted by social identity theory, higher amounts of derogation of the threat-relevant outgroup in the identity-threatened condition elevated subsequent collective self-esteem. Derogation of threat-irrelevant outgroups did not have this positive esteem consequence; in fact, increased derogation of irrelevant outgroups reduced subsequent self-esteem. In the no-threat condition, amount of derogation directed towards either type of outgroup did not significantly influence subsequent self-esteem, with the overall pattern being opposite to what was observed in the threat condition. Implications for theories concerning self-processes as instigators of outgroup derogation and the consequences of intergroup comparisons for collective self-esteem are discussed.

Segmental analysis of the sagittal plane alignment of the normal thoracic and lumbar spines and thoracolumbar junction

Abstract: Recent advances in spinal instrumentation have brought about a new emphasis on the three-dimensional spinal deformity of scoliosis and especially on the restoration of normal sagittal plane contours. Normal alignment in the coronal and transverse planes is easily defined; however, normal sagittal plane alignment is not so simple. This retrospective study was undertaken to increase the understanding of the normal alignment of the spine in the sagittal plane, with a special emphasis on the thoracolumbar junction. Measurements were made from the lateral radiographs of 102 subjects with clinically and radiographically normal spines. Cobb measurements of the thoracic kyphosis (T3-T12), the thoracolumbar junction (T10-T12 and T12-L2), and the lumbar lordosis (L1-L5) were determined. The spices of the thoracic kyphosis and lumbar lordosis also were determined. Using a computerized digitalizing table, the segmental angulation was determined at each level from T1-2 to L5-S1. In conclusion, there is a wide range of normal sagittal alignment of the thoracic and lumbar spines. When using composite measurements of the combined frontal and sagittal plane deformity of scoliosis, this wide range of sagittal variance should be taken into consideration. Using norms established here for segmental alignment, areas of hypokyphosis and hypolordosis commonly seen in scoliosis can be more objectively evaluated. The thoracolumbar junction is for all practical purposes straight; lumbar lordosis usually starts at L1-2 and gradually increases at each level caudally to the sacrum.

A World of Standards but not a Standard World: Toward a Sociology of Standards and Standardization *

Abstract: Standards and standardization aim to render the world equivalent across cultures, time, and geography. Standards are ubiquitous but underappreciated tools for regulating and organizing social life in modernity, and they lurk in the background of many sociological works. Reviewing the relevance of standards and standardization in diverse theoretical traditions and sociological subfields, we point to the emergence and institutionalization of standards, the difficulties of making standards work, resistance to standardization, and the multiple outcomes of standards. Rather than associating standardization with totalizing narratives of globalization or dehumanization, we call for careful empirical analysis of the specific and unintended consequences of different sorts of standards operating in distinct social domains.
