Cognitive Vulnerability-Stress Theories of Depression: Examining Affective Specificity in the Prediction of Depression Versus Anxiety in Three Prospective Studies.

Abstract: Anxiety and depression overlap extensively at the level of symptoms and disorder. We tested the etiological factors from two cognitive vulnerability-stress models of depression (Hopelessness theory and Beck’s theory) for specificity in predicting depression compared with anxiety. Multiple symptom measures of anxiety and depression with good discriminant validity, diagnoses of anxiety and depression, cognitive vulnerability (negative cognitive style and dysfunctional attitudes), and negative events were assessed in three prospective studies: one with a short-term (5-weeks) follow-up, the second with a long-term (2-years) follow-up, and the third with an academic midterm design. Results show that negative events were a general risk factor for anxiety and depression. Cognitive vulnerability for depression interacted with negative events to predict future depression specifically but not anxiety. Comparison of the two theories suggests that their cognitive vulnerability-stress components overlap largely in the prediction of depression. Implications for the co-occurrence of anxiety and depression as well as for the cognitive vulnerability-stress theories of depression are discussed.

The Internet of Things: Review and theoretical framework

Abstract: The Internet of Things (IoT) global arena is massive and growing exponentially. Those in the emerging digital world have recently witnessed the proliferation and impact of IoT-enabled devices. The IoT has provided new opportunities in the technology arena while bringing several challenges to an increased level of concern. This research has both practical and theoretical impetus since IoT is still in its infancy, and yet it is considered by many as the most important technology initiative of today. This study includes a systematic review and synthesis of IoT related literature and the development of a theoretical framework and conceptual model. The review of the literature reveals that the number of applications that make use of the IoT has increased dramatically and spans areas from business and manufacturing to home, health care, and knowledge management. Although IoT can create invaluable data in every industry, it does not occur without its challenges. The theoretical framework developed identifies IoT priority areas and challenges, providing a guide for those leading IoT initiatives and revealing opportunities for future IoT research.

Ultramicroelectrodes: Design, Fabrication, and Characterization

Abstract: Ultramicroelectrodes (UMEs) have led to unprecedented advances in electrochemical studies since their introduction to electroanalytical chemistry about twenty five years ago. During this time, several UME geometries have been reported of which disk, ring, ring-disk, hemispherical, spherical, and etched (finite cone) UMEs are the most commonly used. In this review, the design and fabrication procedures for each are described. Issues related to UME electrode surface treatment and characterization are also addressed.
