First-Order, Second-Order, and Third-Order Change and Organization Development Interventions: A Cognitive Approach:

Abstract: This article discusses how recent developments in the cognitive sciences, especialy the concept of schemata (organizing frameworks for understanding events), can illumine the practice of organization development. On the basis of a cognitive perspective, the authors discuss the relationship between organizational change and schemata, describing the following orders of change that might result from OD: first-order change, or incremental changes occurring within particular schemata already shared by members of a client system, second-order change, or modifications in the shared schemata themselves; and third-order change, or the development of the capacity of the client system to change the schemata as events require. To show how understanding the differences among orders of change can help clarify problems and solutions from an intervention, the authors discuss how a paternalism schema affected a particular quality of working life intervention. They conclude by suggesting implications of the cognitive persp...

A Theoretical Framework for Understanding Help‐Seeking Processes Among Survivors of Intimate Partner Violence

Abstract: This paper suggests a conceptual framework for understanding the processes of help-seeking among survivors of intimate partner violence (IPV). A cognitive theory from general literature on help-seeking in "stigmatizing" situations suggests three relevant processes or stages of seeking help in the IPV context: defining the problem, deciding to seek help, and selecting a source of support. Individual, interpersonal, and sociocultural factors that influence decision-making at each of these stages are discussed and illustrated with case examples.

Microscopic electronic inhomogeneity in the high-Tc superconductor Bi2Sr2CaCu2O8+x.

Abstract: The parent compounds of the copper oxide high-transition-temperature (high-Tc) superconductors are unusual insulators (so-called Mott insulators). Superconductivity arises when they are 'doped' away from stoichiometry. For the compound Bi2Sr2CaCu2O8+x, doping is achieved by adding extra oxygen atoms, which introduce positive charge carriers ('holes') into the CuO2 planes where the superconductivity is believed to originate. Aside from providing the charge carriers, the role of the oxygen dopants is not well understood, nor is it clear how the charge carriers are distributed on the planes. Many models of high-Tc superconductivity accordingly assume that the introduced carriers are distributed uniformly, leading to an electronically homogeneous system as in ordinary metals. Here we report the presence of an electronic inhomogeneity in Bi2Sr2CaCu2O8+x, on the basis of observations using scanning tunnelling microscopy and spectroscopy. The inhomogeneity is manifested as spatial variations in both the local density of states spectrum and the superconducting energy gap. These variations are correlated spatially and vary on the surprisingly short length scale of approximately 14 A. Our analysis suggests that this inhomogeneity is a consequence of proximity to a Mott insulator resulting in poor screening of the charge potentials associated with the oxygen ions left in the BiO plane after doping, and is indicative of the local nature of the superconducting state.
