Using Pre-Session Mindfulness to Improve Session Presence and Effectiveness: A Randomized-Controlled Trial
While a significant amount of research illustrates the overall positive effects of therapists' general use of mindfulness, very few studies have addressed whether therapists' use of mindfulness translates to improved psychotherapy outcomes. The present study utilized a randomized-controlled design to test whether a brief mindfulness training program and pre-session mindfulness practice could have a positive impact on therapy; in particular, we hypothesized that mindfulness training and practice would improve ratings on therapeutic presence as rated by clients and therapists and session effectiveness as rated by clients. The present study also examined whether clients' subjective ratings of therapy outcome and therapists' theoretical orientation impacted outcome measures after therapists completed mindfulness training. The 20 participating therapists were randomly assigned to either the mindfulness training (MT) group or control group according to a computer generated randomization list. Results indicated that clients did not significantly improve on outcome measures after completing the mindfulness training. Clients' subjective ratings on a psychotherapy outcome measure did predict changes in their ratings of therapeutic presence. This finding may have important implications for future research examining client characteristics that may moderate the relationship between therapeutic presence and session outcomes. Limitations of the present study and future directions are discussed.

Direct Atomic Level Controlled Growth and Characterization of h-BN and Graphene Heterostructures on Magnetic Substrates for Spintronic Applications
Epitaxial multilayer h-BN(0001) heterostructures and graphene/h-BN heterostructures have many potential applications in spintronics. The use of h-BN and graphene require atomically precise control and azimuthal alignment of the individual layers in the structure. These in turn require fabrication of devices by direct scalable methods rather than physical transfer of BN and graphene flakes, and such scalable methods are also critical for industrially compatible development of 2D devices. The growth of h-BN(0001) multilayers on Co and Ni, and graphene/h-BN(0001) heterostructures on Co have been studied which meet these criteria. Atomic Layer Epitaxy (ALE) of BN was carried out resulting in the formation of macroscopically continuous h-BN(0001) multilayers using BCl3 and NH3 as precursors. X-ray photoemission spectra (XPS) show that the films are stoichiometric with an average film thickness linearly proportional to the number of BCl3/NH3 cycles. Molecular beam epitaxy (MBE) of C yielded few layer graphene in azimuthal registry with BN/Co(0001) substrate. Low energy electron diffraction (LEED) measurements indicate azimuthally oriented growth of both BN and graphene layers in registry with the substrate lattice. Photoemission data indicate B:N atomic ratios of 1:1. Direct growth temperatures of 600 K for BN and 800 to 900 K for graphene MBE indicate multiple integration …

A Comparison of Treatments for Posttraumatic Stress Disorder Symptoms: Memory Specificity Training (MeST) and Cognitive Processing Therapy (CPT)
The effectiveness of memory specificity training (MeST) was compared with standard cognitive processing therapy (CPT) in treatment of individuals with posttraumatic stress disorder. Eighteen adults aged 18-36 were randomly assigned to the MeST intervention (n = 9) or to the active control group (n = 9) of CPT. Both treatments were administered in group format across 6 weeks. MeST consisted of 6 weekly sessions, while CPT consisted of 12 biweekly sessions. The trial was undertaken in the Psychology Clinic of the University of North Texas, with randomization to conditions accomplished via computer random number generator. The primary outcome measure was change in PTSD symptoms post-treatment from baseline. Sixteen individuals (13 women and 3 men; MeST n = 8 and CPT n = 8) completed treatment and their data was analyzed. MeST significantly decreased PTSD symptomology at post-treatment and these results were maintained at 3 months post-treatment. MeST was found to be as effective as the established CPT intervention at reducing PTSD symptomology. Both MeST and CPT significantly increased participants' ability to specify memories upon retrieval at post-treatment, with results maintained at follow-up. There were no significant effects of MeST or CPT in ability to increase overall controlled cognitive processing at …

Analysis and Optimization of Graphene FET based Nanoelectronic Integrated Circuits
Like cell to the human body, transistors are the basic building blocks of any electronics circuits. Silicon has been the industries obvious choice for making transistors. Transistors with large size occupy large chip area, consume lots of power and the number of functionalities will be limited due to area constraints. Thus to make the devices smaller, smarter and faster, the transistors are aggressively scaled down in each generation. Moore's law states that the transistors count in any electronic circuits doubles every 18 months. Following this Moore's law, the transistor has already been scaled down to 14 nm. However there are limitations to how much further these transistors can be scaled down. Particularly below 10 nm, these silicon based transistors hit the fundamental limits like loss of gate control, high leakage and various other short channel effects. Thus it is not possible to favor the silicon transistors for future electronics applications. As a result, the research has shifted to new device concepts and device materials alternative to silicon. Carbon is the next abundant element found in the Earth and one of such carbon based nanomaterial is graphene. Graphene when extracted from Graphite, the same material used as the lid in pencil, …

Simulink® Based Design and Implementation of a Solar Power Based Mobile Charger
Electrical energy is used at approximately the rate of 15 Terawatts world-wide. Generating this much energy has become a primary concern for all nations. There are many ways of generating energy among which the most commonly used are non-renewable and will extinct much sooner than expected. Very active research is going on both to increase the use of renewable energy sources and to use the available energy with more efficiency. Among these sources, solar energy is being considered as the most abundant and has received high attention. The mobile phone has become one of the basic needs of modern life, with almost every human being having one.Individually a mobile phone consumes little power but collectively this becomes very large. This consideration motivated the research undertaken in this masters thesis.

Feasibility of a New Technique to Determine Dynamic Tensile Behavior of Brittle Materials
Dynamic tensile characterization of geo-materials is critical to the modeling and design of protective structures that are often made of concrete. One of the most commonly used techniques currently associated with this type of testing is performed with a Kolsky bar and is known as the spall technique. The validity of the data from the spall technique is highly debated because the necessary boundary conditions for the experiment are not satisfied. By using a technique called pulse shaping, a new “controlled” spall technique was developed to satisfy all boundary conditions so that the analyzed data may be useful in modeling and design. The results from this project were promising and show the potential to revolutionize the way Kolsky bar testing is performed.

Determinants of Women's Autonomy in Nepal
Nepal in recent times has witnessed a proliferation of community-based organization (CBOs). Established by local residents, CBOs are small level organizations that promote and defend the rights and interests of people especially that of minorities and the disadvantaged. One such minority group that CBOs greatly focus on are women. Despite dramatic increase in the number of CBOs in Nepal its impact on women is understudied. The purpose of this dissertation is to analyze the relationship between Nepalese women's participation in CBOs and their autonomy. Autonomy comprises of four different dimensions; physical mobility, financial autonomy, household decision-making, and reproductive autonomy. Modifying the conceptual framework used by Mahmud, Shah, and Becker in 2012, I hypothesize that women who participate in CBOs experience greater autonomy. Data from the 2008 Chitwan Valley Family Study is used for analysis. Using SPSS, separate logistic regressions are run to analyze the relationship between CBO membership and the dimensions of autonomy. The results support three of the four proposed major hypotheses. Nepalese women who participate in CBOs have greater autonomy in terms of physical mobility, financial autonomy, and household decision-making. No evidence was found to establish link between CBO membership and reproductive autonomy. The variables that are controlled …

A Laboratory Human Operant Examination of Extinction Bursts
The present study examined operant extinction in a controlled setting using a human operant paradigm. Participants watched a preferred video. During the video, either the video or audio portion of the video was selectively removed, on average every 15 s. Participants could restore the video by pressing a force transducer. In one group, relatively low forces were required (250 g) and in the other relatively high forces were required (750 g). At the 20th and 30th minute during the session, the video or audio was removed but the participants could not restore the component for 30 s. The results showed that responding during the probe increased relative to 30-s periods prior and following the probe, characteristic of an extinction burst. The results also showed that overall we saw increases in force under high force conditions during extinction when presses no longer produced sound or video, and force changed little during the low force conditions. We conclude that extinction bursts are a robust phenomenon that can be demonstrated in humans. Additionally, the topographies, i.e. force, established during baseline and the modality of the consequence appear to be two variables determining the short-term course of extinction.

The Effects of Child Parent Relationship Therapy (CPRT) for Adoptive Families
Adoptive parents often struggle to understand and meet the social-emotional behavioral needs of their adopted child, particularly when the child's pre-adoption experience lacked a secure relationship with an attuned and responsive caregiver. This randomized controlled study, a replication of Carnes-Holt and Bratton's 2014 research, investigated the effects of child parent relationship therapy (CPRT) for adoptive families who reported attached-related concerns such as difficulties establishing a mutually satisfying parent-child relationship as well as concerns about the adopted child's behavior and parental stress. Participants were 49 adoptive parents (61% female; 7% couples; 86% European American, 6% Latino, 6% Asian, and 2% Black American) with adoptees between the ages of 2.5 to 9 (50% female; 35% European American, 22% Asian, 12% Latino, 10% Black American, and 21% Biracial or other). Eighty-four percent of children were adopted internationally or from the foster care system. Parents were randomly assigned to CPRT or treatment as usual (TAU). Results from 2 (group) by 2 (time) repeated measures ANOVAs indicated that compared to the TAU control group, parents who participated in CPRT reported statistically significant improvement in child behavior problems, parent-child relationship stress, and parental empathy, with a large treatment effects on all measures. Findings confirmed results from …
