    Transformation of Cognitive Behavior Therapy as a Psychotherapeutic Intervention in Contemporary Health Care: A Review

    Get PDF
    Cognitive behavior therapy (CBT) is an evidence-based intervention in contemporary clinical health care services. CBT was developed as a psychotherapy to overcome the deficits of psychoanalysis and behaviorism by Aron T. Beck. However, after 63 years, CBT has transformed from its early framework. In comparison to other psychotherapies, cognitive behavior therapy has rapidly changed and developed as an evidence-based clinical intervention. Therefore, this study explored the evolution of cognitive behavior therapy by focusing on its origin, development, limitations, clinical application, third waves, and future directions. Early CBT therapeutic framework has developed as a cognitive model of depression and developed as an intervention to address the negative core belief of individuals and rationalize maladaptive behaviors, thoughts, and emotions. However, clinicians have experienced several limitations and scholars have recognized theoretical limitations in CBT. Later, scholars on CBT have overcome these deficits and developed disorder-specific CBT therapies. Then, clinicians empirically evaluate those therapeutic frameworks and transform CBT into an evidence-based clinical intervention. Further, CBT has strength in integrating third-wave therapies. In the future, CBT will therapeutically further transform with technology, integrating advanced theories of pathology, and clinical demand of the present health care services. Therefore, as a psychotherapeutic intervention, cognitive behavior therapy has transformed from its early framework, and at present, it has developed empirically. Further, in the future, it will transform into a more effective psychotherapeutic intervention.   DOI: http://doi.org/10.31357/fhss/vjhss.v08i02.1

    Free vibration of a three-layered sandwich beam using the dynamic stiffness method and experiment

    Get PDF
    In this paper, an accurate dynamic stiffness model for a three-layered sandwich beam of unequal thicknesses is developed and subsequently used to investigate its free vibration characteristics. Each layer of the beam is idealised by the Timoshenko beam theory and the combined system is reduced to a tenth-order system using symbolic computation. An exact dynamic stiffness matrix is then developed by relating amplitudes of harmonically varying loads to those of the responses. The resulting dynamic stiffness matrix is used with particular reference to the Wittrick-Williams algorithm to carry out the free vibration analysis of a few illustrative examples. The accuracy of the theory is confirmed both by published literature and by experiment. The paper closes with some concluding remarks. (c) 2007 Elsevier Ltd. All rights reserved

    Single side damage simulations and detection in beam-like structures

    Get PDF
    Beam-like structures are the most common components in real engineering, while single side damage is often encountered. In this study, a numerical analysis of single side damage in a free-free beam is analysed with three different finite element models; namely solid, shell and beam models for demonstrating their performance in simulating real structures. Similar to experiment, damage is introduced into one side of the beam, and natural frequencies are extracted from the simulations and compared with experimental and analytical results. Mode shapes are also analysed with modal assurance criterion. The results from simulations reveal a good performance of the three models in extracting natural frequencies, and solid model performs better than shell while shell model performs better than beam model under intact state. For damaged states, the natural frequencies captured from solid model show more sensitivity to damage severity than shell model and shell model performs similar to the beam model in distinguishing damage. The main contribution of this paper is to perform a comparison between three finite element models and experimental data as well as analytical solutions. The finite element results show a relatively well performanc

    Feasibility of valuing credit risk in the financial market in Sri Lanka: a case study

    Get PDF
    The Sri Lankan financial market uses non analytical techniques to quantify credit risk. Credit derivatives are not used to transfer credit risk. A Credit Default Swap (CDS) is the most widely used credit derivative to manage credit risk. To evaluate the price of CDS, various sophisticated methods are used. This research paper focuses on techniques to hedge credit risk in the Sri Lankan financial market, the behaviours of CDS in derivative markets, calculating a fair value of CDS, the main advantages of using credit derivatives, and major imperfections to use the pricing process of CDS in the Sri Lankan marke
