There are a number of advantages to working within an integrated model framework when doing family therapy; however, few therapists test what they articulate as their model against what they really do. The purpose of this study was to test how well one therapist practiced her explicated theoretical integration in a clinical setting. Quantitative and qualitative data were gathered to answer three research questions: the level of adherence to the integration, client change, and change within the integrated model over the course of the study. The sample included three couples; data from 25 video-coded sessions, the Revised Dyadic Adjustment Scale and Outcome Ratings Scale, client case notes, and a reflection journal were analyzed to answer the research questions. Results indicate that the therapist remained true to the described integrated model; that all couples experienced change, some positive, some negative; and small changes to the model occurred. Other findings, limitations, and clinical implications are discussed.

Collected papers where problems involving non-relativistic systems are solved by means of a proper Effective Field Theory. Those problems include the calculation of the lifetime of pionium, the lepton finite mass corrections from vacuum polarization to non-relativistic bound state energies and wave function at the origin, the analysis of the Nucleon-Nucleon OPE (one pion exchange) interactions from a renormalization point of view and heavy quarkonia P-wave hadronic decays. / Aquesta tesi presenta un recull de publicacions on problemes relatius a sistemes no relativistes són adreçats mitjançant l'apropiada EFT (Effective Field Theory). Entre les esmentades aplicacions s'inclou el càlcul de la vida mitjana del pionium, correccions a les energies d'estats lligats i funció d'ona a l'origen degudes a la massa finita del leptó en la polarització del buit, l'anàlisi de la interacció OPE (one pion exchange) des del punt de vista de la seva renormalització i, finalment, decaiments hadrònics d'ones P en "heavy quarkonia".

This is a longitudinal couples therapy process study using coded data from eleven couples to identify which therapist behaviors (warmth, listener responsiveness, communication, dominance) influenced positive couples exchanges (warmth and listener responsiveness) over time in Emotionally Focused Couples Therapy (EFT). A mixed effects model was used to examine within- and between-individual variability. Men and women were modeled separately. A series of two-level multilevel models of change were examined, where Time is Level 1 and Individual is Level 2. Results indicated no significant relationship between variables of therapist warmth, listener responsiveness, communication, and dominance with couple listener responsiveness. Where client warmth was an outcome variable, the only significant relationship was between therapist warmth toward husband and husband warmth toward wife. Findings demonstrated that 62.9% of the variance in husband warmth toward wife was accounted for by therapist warmth to husband across time in therapy. Specifically, therapist warmth toward husband was significantly and positively related to husband warmth toward wife over time in therapy. Clinical implications and directions for future research are discussed.

This is a longitudinal multilevel analysis using third party coded data of 15 couples therapy sessions to identify which therapist Emotion Focused Therapy interventions (Management of Couple's Interaction, Working with Primary Emotion, Managing Defensive Responses, Reframing the Problem in Terms of the Cycle, and Placing Emerging Emotions into the Cycle) influenced husband-to-wife and wife-to-husband exchanges of Positive Behaviors (warmth, prosocial behaviors, communication, assertiveness, and listening). A mixed effects model was used to examine within- and between-individual variability. Men and women were modeled separately. A series of two-level multilevel models of change were examined, where Time is Level 1 and Individual is Level 2. Results indicated no significant relationship between Management of the Couple's Interaction, Managing Defensive Responses, and Reframing the Problem in Terms of the Cycle with both wife-to-husband and husband-to-wife positive behavior. Findings demonstrated that 44.5% of the variance in wife-to-husband positive behaviors and 66.5% of the variance in husband-to-wife positive behaviors was accounted for by the therapist Working with Primary Emotion and Placing Emerging Emotions in the Cycle. Specifically, these therapist interventions were significantly and negatively related to wife-to-husband and husband-to-wife positive behaviors over time in therapy. Clinical implications and directions for future research will be discussed.

In the U.S., an estimated 61 million people identify as having a disability, making up 26% of all adults. The occurrence of a disability for one person within a couple impacts the physical, social, psychological, and emotional state of the person who acquired a disability, forcing changes to quality of life. Interabled couples, defined as one partner having a physical disability and the other partner identifying as nondisabled, navigate various systems of care as they respond to the needs of the partner with the disability. Emotionally focused therapy (EFT) has shown benefits in reducing relationship stress and increasing security within couples. In this study, the researcher explored the experiences of 10 EFT therapists who served at least one interabled couple in couple therapy. Participants completed a semi-structured interview designed to explore how EFT therapists make sense of their lived experiences serving interabled couples. The researcher utilized interpretative phenomenological analysis to understand how EFT therapists made meaning from their experiences serving interabled couples. Findings included four super-ordinate themes that emerged from the data including (a) ableism, (b) self-of-the-therapist, (c) relationship dynamics of interabled couples, and (d) the "fit" of EFT approach with interabled couples. The themes demonstrate a need to further explore disability-responsive practices within EFT in serving interabled couples.

In this thesis, we used Effective Field Theory (EFT) to calculate the radiative ALPHA capture on 12C . This reaction is considered the “holy grail” in nuclear astrophysics because it determines the relevant abundance of 16O and 12C . We considered the E1 transition from initial p-wave at energy around the Gamow energy EG =0.3MeV.The theoretical formula for the cross section is obtained by fitting the EFT parameters to the phase shift and S-factor data. We find the Effective Range Expansion (ERE) parameters describing the ALPHA-wave phase shift are fine tuned. The shallow bound state and the resonance ALPHA-wave states are also described.

In this thesis we study radiative decays of the exotic meson X(3872) into $J/ \\psi \\gamma$ and $\\psi(2S) \\gamma$ using an effective field theory framework. Assuming the exotic meson to be primarily a molecular state of the mesons $D$ and $ \\bar{D}^{*}$, we perform a renormalization analysis to estimate the contribution of the short-distance physics. This is done using two different prescriptions, the popular $\\overline{MS}$ scheme, valid only for perturbative calculations, and the PDS scheme, used in EFTs for loosely-bound systems and intrinsically non-perturbative. We show that, without a short-distance contact interaction, the observables become very dependent on the regularization scale, therefore demanding proper renormalization. We include two short-distance contact terms, one for each decay channel, and impose the renormalization condition within both $\\overline{MS}$ and PDS schemes. We obtain the behavior of the contact term with the renormalization scale $\\mu$, which can be useful in guiding models for the short-distance part. We note, however, distinct behaviors between $\\overline{MS}$ and PDS. Both also lead to lower limits in the decay widths that could, in principle, be tested experimentally. / In this thesis we study radiative decays of the exotic meson X(3872) into $J/ \\psi \\gamma$ and $\\psi(2S) \\gamma$ using an effective field theory framework.
