Use Of Emoticons For Assessing Emotion And Mood States In Web-Based Interventions, Jennifer Chua So Dec 2009

Use Of Emoticons For Assessing Emotion And Mood States In Web-Based Interventions, Jennifer Chua So

Loma Linda University Electronic Theses, Dissertations & Projects

In the rapidly growing field of online psychotherapeutic interventions, an increasing number of clinicians are seeking to extend therapeutic interventions into cyberspace. However, because communication with clients in this medium is often devoid of auditory and visual feedback, these clinicians are not able to rely on their clinical observations. It then becomes incumbent to develop a psychometrically and theoretically sound means of assessing emotion and mood states that can be easily utilized in this forum. Utilizing cross-culturally and empirically supported models of emotion structure shown to be influential in the self-report data, the Positive Affect and Negative Affect factors, this …

Death Comes Alive; Technology And The Re‐Conception Of Death, Karen Cerulo, Janet M. Ruane

Department of Sociology Faculty Scholarship and Creative Works

Browse through your local bookstore, or glance at a nearby movie marquee. Skim the pages of your nightly newspaper or the listings in your television guide. American culture's current focus poses a surprise. The popular eye is centered on a topic more taboo than the steamiest sexual encounter, more solemn than the deepest economic depression, and more universal than the common cold. The current decade reveals a remarkable up- surge in our collective attention toward death. Indeed in the 1990s, Americans have become nearly obsessed with a world that lurks beyond life as we know it.


The Effects Of The Introduction Of An Electronic Medical Record (Emr) On Self-Reported Treatment Effects In A Psychological Service In A Family Medicine Clinic, Michael D. Herman Sep 2009

The Effects Of The Introduction Of An Electronic Medical Record (Emr) On Self-Reported Treatment Effects In A Psychological Service In A Family Medicine Clinic, Michael D. Herman

Loma Linda University Electronic Theses, Dissertations & Projects

The healthcare system in the United States has traditionally focused on pathogenic disease prevention and treatment of acute illness, only addressing physical health (Grzywacz & Keyes, 2004). This approach is limited, as it does not often acknowledge the influence of mental health and health promotion on outcomes. Approximately, 25-75% of all presenting cases with uncertain etiology in medicine are psychosocial or behavioral in origin (Schulte et. al., 2004). Improvements can be made through integrated care; however, divergent viewpoints and often proximity across providers disrupts, psychologist-physician communication, collaboration, and subsequently care access (McDaniel, 1995). The current study examines the self reported …

Resolving The Lateral Component Of Blood Flow Velocity Based On Ultrasound Speckle Size Change With Scan Direction And Speed, Tiantian Xu, Greg R. Bashford Jan 2009

Resolving The Lateral Component Of Blood Flow Velocity Based On Ultrasound Speckle Size Change With Scan Direction And Speed, Tiantian Xu, Greg R. Bashford

Biomedical Imaging and Biosignal Analysis Laboratory

Conventional blood flow velocity measurement using ultrasound is capable of resolving the axial component (i.e., that aligned with the ultrasound propagation direction) of the blood flow velocity vector. However, these Doppler-based methods are incapable of detecting blood flow in the direction normal to the ultrasound beam. In addition, these methods require repeated pulse-echo interrogation at the same spatial location. In this paper, we introduce a method which estimates the lateral component of blood flow within a single image frame using the observation that the speckle pattern corresponding to the blood reflectors (typically red blood cells) stretches (i.e., is “smeared”) if …

Conventional blood flow velocity measurement using ultrasound is capable of resolving the axial component (i.e., that aligned with the ultrasound propagation direction) of the blood flow velocity vector. However, these Doppler-based methods are incapable of detecting blood flow in the direction normal to the ultrasound beam. In addition, these methods require repeated pulse-echo interrogation at the same spatial location. In this paper, we report additional data on a new method recently introduced. This method estimates the lateral component of blood flow within a single image frame using the observation that the speckle pattern corresponding to the blood reflectors (typically red …


Single Molecule Diffusion Coefficient Estimation By Image Analysis Of Simulated Ccd Images To Aid High-Throughput Screening, Pengfei Song, Lloyd M. Davis, Greg Bashford Jan 2009

Single Molecule Diffusion Coefficient Estimation By Image Analysis Of Simulated Ccd Images To Aid High-Throughput Screening, Pengfei Song, Lloyd M. Davis, Greg Bashford

Biomedical Imaging and Biosignal Analysis Laboratory

Extension of one-dimensional signal analysis to two-dimensional image analysis could accelerate conventional methods of high-throughput screening in the discovery of new pharmaceutical agents. This work describes a first step taken towards this goal – the evaluation of image-analysis based estimation strategies of the diffusion coefficient of a single molecule transported within a microfabricated flowcell. A computer simulation of single-molecule imaging by a charge-coupled device (CCD) camera is used to determine if it is possible to distinguish three different types of molecules with different diffusion coefficients. The Gaussian fitting algorithm finds the variance of the transverse trajectory, which increases linearly with …


Optimal Thresholds Of Feature Tracking For Blood Velocity And Tissue Motion Estimation, Tiantian Xu, Gregory R. Bashford Jan 2009

Optimal Thresholds Of Feature Tracking For Blood Velocity And Tissue Motion Estimation, Tiantian Xu, Gregory R. Bashford

Biomedical Imaging and Biosignal Analysis Laboratory

Feature tracking is an algorithm for estimating blood flow velocity and tissue motion using pulse-echo ultrasound. In contrast to cross-correlation speckle-tracking techniques, feature tracking identifies features at discrete locations and corresponds them from frame to frame. Prior studies have demonstrated that feature-tracking estimates exhibit lower variance than those obtained by the conventional autocorrelation method and require less computational complexity than either speckle tracking or autocorrelation. To date, not much attention has been paid to the process by which trackable features (normally local maxima) are selected from the set of all available features. In the selection process, it is desired to …

Predicting Patients’ Use Of Provider-Delivered E-Health: The Role Of Facilitating Conditions, E. Vance Wilson, Nancy K. Lankton Jan 2009

Predicting Patients’ Use Of Provider-Delivered E-Health: The Role Of Facilitating Conditions, E. Vance Wilson, Nancy K. Lankton

Accounting Faculty Research

This chapter presents a new rational-objective (R-O) model of e-health use that accounts for effects of facilitating conditions as well as patients’ behavioral intention. An online questionnaire measured patients’ behavioral intention to use a new e-health application as well as proxy measures of facilitating conditions that assess prior use of and structural need for health services. A second questionnaire administered three months later collected patients’ self-reported use of e-health during the intervening period. The new model increased predictions of patients’ e-health use (measured in R2) by more than 300% over predictions based upon behavioral intention alone, and all measured factors …

The Influence Of Affect, Attitude And Usefulness In The Acceptance Of Telemedicine Systems, Soussan Djamasbi,, Ann L. Fruhling, Eleanor T. Loiacono

Information Systems and Quantitative Analysis Faculty Publications

Grounded in current theories of affect this study examines the role positive and negative moods play on the acceptance of a specialized telemedicine system for microbiology consultation and diagnostics, referred to as telepathology. From a laboratory experiment using microbiology laboratory assistants, the notion that healthcare users’ attitude is an important factor in the acceptance behavior of a healthcare information system is supported. A regression analysis of the data revealed the need to tailor the IS Technology Acceptance Model for the healthcare field. Specifically, our results show that ease of use which is thought to be a main antecedent of end-user …
