Abstract

Despite extensive theorizing regarding the regulatory role of reflective functioning (RF), few studies have explored the links between RF and physiological indices of emotion regulation, and none have examined these associations in children. Further, while scholars contend that RF promotes resilience via enhanced ability to process emotional experiences, including those occurring in attachment relationships, this argument has seldom been tested empirically in children. In the current study, we explore the association between RF and physiological measures of emotion reactivity and regulation, as well as the interaction of RF and attachment insecurity. We test these associations by examining children's (N = 76; 8-12 years old) cardiovascular responses [respiratory sinus arrhythmia (RSA)] to a standardized paradigm designed to evoke reactions regarding the experience and expression of attachment-related needs. Children also completed a semi-structured attachment interview, which was later coded for children's attachment insecurity (operationalized as attachment dismissal and preoccupation) and RF. Our findings were largely consistent with theory and our hypotheses, suggesting that higher RF is associated with lesser cardiovascular reactivity (higher levels of RSA) during the stressor task and better recovery following the task. These links were especially strong for children with greater attachment preoccupation but did not vary as a function of children's levels of attachment dismissal. These findings contribute to developmental theory in suggesting that RF is closely linked to physiological emotion regulation in children.

8. The physical modelling of heterojunction field effect transistors

Abstract

This project is primarily concerned with the incorporation of quantum effects into physical models for heterojunction field effect transistors. Several simulations have been developed including a one-dimensional Schottky-gate model which self-consistently solves the effective mass Schrodinger equation with Poisson’s equation. This model employs a fast, accurate and robust solution algorithm based upon an expanded Newton scheme. This work is extended to two-dimensions, permitting charge transport and hence adding the current-continuity equation. All three equations are solved under non-equilibrium conditions. Finally a quasi-two-dimensional HFET model has been written, also including quantum mechanics which produces excellent agreement with measured characteristics. As a rigorous solution of the full two-dimensional Schrodinger equation and corresponding transport equation is very demanding and computationally expensive the problem has been simplified to by assuming the electron wavefunction to take the form of Bloch, or travelling wave solutions is the directions parallel to the heterojunction interface is then solved by taking multiple one-dimensional solutions sampled at various positions throughout the device. This new approach requires alternative solution algorithms to be developed since the conventional schemes are not applicable. This thesis reviews the physics behind semiconductor heterojunctions, discusses the solution schemes used in the models and presents results from the one-dimensional, two-dimensional and quasi-two-dimensional simulations.

12. New and Emerging Technologies for Integrative Ambulatory Autonomic Assessment and Intervention as a Catalyst in the Synergy of Remote Geocoded Biosensing, Algorithmic Networked Cloud Computing, Deep Learning, and Regenerative/Biomic Medicine: Further Real

Author

L., Drury, Robert

Abstract

While the important role of the autonomic nervous system (ANS) has been historically underappreciated, recently there has been a rapid proliferation of empirical, methodological and theoretical progress in our more detailed understanding of the ANS. Previous more simplistic models of the role of the ANS using the construct of homeostasis have been enhanced by the use of the construct of allostasis and a wide variety of technological innovations including wearable and implantable biosensors have led to improved understanding of both basic and applied knowledge. This chapter will explore in particular heart rate variability (HRV) as a rich variable which has developed an extensive literature, beginning with predicting all-cause mortality, but now encompassing a wide variety of disease and illness states; cognitive, affective and behavioral processes and performance optimization. A critical analysis of HRV from the perspective of complex adaptive systems and non-linear processes will be included and innovative future uses of HRV will be described.

13. Behavioral Outcomes for Predelinquents Receiving Behavioral, Generic, or No Counseling.

Author

Drury, Robert L. and Robbins, Carol A.

Abstract

Thirty-six students at a continuation high school were identified as predelinquents and selected as subjects on the basis of their poor attendance and academic records. Pretreatment and posttreatment data were collected on the following variables: attendance figures and academic credits. Following preliminary assessment, the subjects were randomly assigned to one of three conditions: treatment by a behaviorally trained counselor, treatment by a generically trained counselor, or no treatment. Counselors were New Careerists who were divided into two matched groups. The groups received one month of either behavioral or generic counselor training. After a time-limited treatment period, the assessment procedure was readministered, so that the relative efficacy of the differentially trained counselors could be evaluated. Significant differences favoring the behaviorally trained counselors were found for both dependent variables. (Author)

Abstract

A quasi-two-dimensional high electron mobility transistor (HEMT) model is proposed, consisting of quantum mechanical free electron concentration, a two-dimensional charge-control approach, and a detailed energy transport model. It is capable of self-consistent solution of Schrodinger and Poisson equations. It can solve the physical device equations efficiently. Applications of the model to the dc and microwave analyses of AlGaAs/GaAs and pseudomorphic HEMT's are discussed.

38. HRV in an Integrated Hardware/Software System Using Artificial Intelligence to Provide Assessment, Intervention and Performance Optimization

Abstract

Heart rate variability (HRV) is increasingly recognized as a central variable of interest in health maintenance, disease prevention and performance optimization. It is also a sensitive biomarker of health status, disease presence and functional abilities, acquiring and processing high fidelity inter beat interval data, along with other psychophysiological parameters that can assist in clinical assessment and intervention, population health studies/digital epidemiology and positive performance optimization. We describe a system using high-throughput artificial intelligence based on the KUBIOS platform to combine time, frequency and nonlinear data domains acquired by wearable or implanted biosensors to guide in clinical assessment, decision support and intervention, population health monitoring and individual self-regulation and performance enhancement, including the use of HRV biofeedback. This approach follows the iP4 health model which emphasizes an integral, personalized, predictive, preventive and participatory approach to human health and well-being. It therefore includes psychological, biological, genomic, sociocultural, evolutionary and spiritual variables as mutually interactive elements in embodying complex systems adaptation.
