Abstract In this paper a package is introduced which handles shape optimization in 2-dimensional elasticity problems where Boundary Element Method is used for the analysis phase affording a large reduction in the problem dimensionality together with a variant of the Method of Center Points for the optimization phase. This optimization method allows a high reduction in the number of constraints considered in each step, as well as low number of cycles, resulting in notable overall efficiency. Design variables in optimum shape determination consists of basic nodal coordinates for B-spline functions as the means to define smooth boundary curves. Maximum stress and/or displacements at critical boundary points are observed as constraints in each cycle of the procedure. Three classical case examples are solved successfully, and the results are compared with those of others, illustrating the superior capabilities of the program package.

In this paper, we discuss the application of mathematical formulas to guide the development of clinical interventions in voice disorders. Discussion of case examples includes fundamental frequency and intensity deviations, pitch and loudness abnormalities, laryngeal hyperand hypoadduction, and phonatory effort. The paper illustrates the interactive nature of theoretical and applied work in vocology

The effectiveness of amplification for infants and children can be mediated by how much the child uses the device. Existing research suggests that establishing hearing aid use can be challenging. A wide range of factors can influence hearing aid use in children, including the child's age, degree of hearing loss, and socioeconomic status. Audiological interventions, including using validated prescriptive approaches and verification, performing on-going training and orientation, and communicating with caregivers about hearing aid use can also increase hearing aid use by infants and children. Case examples are used to highlight the factors that influence hearing aid use. Potential management strategies and future research needs are also discussed.

In this article the author explores the use of imagination and clinical intuition in psychotherapy. She discusses the functions of imagination and how the capacity to be creative and for flexible imagining emerges within a secure attachment relationship in early childhood. Winnicott's ideas are important here. She also discusses what happens when trauma or relationship failings compromise the transitional space and uses case examples to illustrate some responses to this breakdown. To set the scene the author discusses changing views on illusion and imagination from Freud onwards to the present day when we are informed by recent findings in neuroscience and interpersonal neurobiology. It is richly illustrated with theory and case material.


Background: The pupillary reaction is controlled by the two main branches of the autonomic nervous system, namely the parasympathetic and sympathetic nervous systems. New discoveries in pupil research has identified that intrinsically photosensitive retinal ganglion cells have an impact on pupillary constriction, particularly sustained pupillary constriction. In the current paper, an objective measurement of sustained pupillary constriction versus the inability to maintain sustained pupillary constriction are observed. The variability in the sustained pupillary constriction, i.e. Alpha Omega pupil, can be objectively identified with the use of modern technology. Case Examples: Two female subjects were adapted to dim illumination, and then two objective pupil measurements of the right eye using Reflex – PLR Analyzer by BrightLamp© (Indianapolis, IN, USA) with sustained illumination were obtained. Subject 1, a 25 year-old-female, demonstrated normal ability of the pupil to constrict and sustain constriction for 10 seconds. She was used as a control for subject 2. Subject 2, a 27 year-old-female, demonstrated the inability to sustain pupillary constriction. She reported being under great psychological stress. Her pupil began to re-dilate between 2 and 3 seconds after the initial constriction. Conclusion: Objective pupillometry can be used to assist in many diagnoses and provides the clinician invaluable information on the state of the individual, and qualifications of sustained pupillary constriction can now be assessed in an objective manner.
