Current practice in space charge and polarization profile measurements using thermal techniques

With the advent of coherent electron sources with cold field emission guns (cFEGs), it has become possible to utilize the coherent interference phenomenon and perform “practical” electron holography. Historically, holography was envisioned to extent the resolution limit by compensating coherent aberrations. Indeed such work has been done with reasonable success in a few laboratories around the world. However, it is the ability of electron holography to map electrical and magnetic fields which has caught considerable attention of materials science community.There has been considerable theoretical work on formation of space charge on surfaces and internal interfaces. In particular, formation and nature of space charge have important implications for the performance of numerous electroceramics which derive their useful properties from electrically active grain boundaries. Bonnell and coworkers, in their elegant STM experiments provided the direct evidence for GB space charge and its sign, while Chiang et al. used the indirect but powerful technique of x-ray microchemical profiling across GBs to infer the nature of space charge.

Opinion Article

Abstract The purpose of this opinion article is to review the impact of the principles and technology of speech science on clinical practice in the area of craniofacial disorders. Current practice relative to (a) speech aerodynamic assessment, (b) computer-assisted single-word speech intelligibility testing, and (c) behavioral management of hypernasal resonance are reviewed. Future directions and/or refinement of each area are also identified. It is suggested that both challenging and rewarding times are in store for clinical researchers in craniofacial disorders.

Solution Focused Therapy

The concept of client-centered therapy (Rogers, 1951) has influenced many professions to refocus their treatment of clients from assessment outcomes to the person who uses the information from this assessment. The term adopted for use in the professions of Communication Sciences and Disorders and encouraged by The American Speech-Language-Hearing Association (ASHA) is patient-centered care, with the goal of helping professions, like audiology, focus more centrally on the patient. The purpose of this paper is to examine some of the principles used in a patient-centered therapy approach first described by de Shazer (1985) named Solution-Focused Therapy and how these principles might apply to the practice of audiology. The basic assumption behind this model is that people are the agents of change and the professional is there to help guide and enable clients to make the change the client wants to make. This model then is focused on solutions, not on the problems. It is postulated that by using the assumptions in this model audiologists will be more effective in a shorter time than current practice may allow.
