The Association Between Trauma History and Body Image, Depression, Posttraumatic Stress, and Relationship Satisfaction in Postpartum Women

The postpartum period can be a time of significant change and transition. Little is known regarding how a history of trauma may impact functioning during this critical time. The literature is consistent regarding the relationship between trauma and body image-related issues, but this has not been investigated with this population. While posttraumatic stress symptoms are considered a significant public health concern, the association between depression and interpersonal concerns has not been thoroughly explored. The purpose of this observational, cross-sectional study is to explore the relationship between trauma and body image, mood, and relationship satisfaction in postpartum women. Proposed Methods: English speaking adult women (age ≥ 18 years, N = 200) who gave birth in the past year and are currently in an intimate relationship will be eligible to participate in the study. Participants will be recruited through social media and online forums that focus on topics related to pregnancy and the postpartum period. Screened and eligible participants will be asked to complete surveys including a demographic and trauma history questionnaire, PTSD Checklist for Diagnostic and Statistical Manual of Mental Disorders-Fifth Edition (PCL-5), Body Attitude Questionnaire (BAQ), Edinburgh Postnatal Depression Scale (EPDS), and The Couples Satisfaction Index (CSI). Survey data will be captured using REDCap. Proposed Hypotheses: Postpartum women who endorse a history of trauma will report significantly greater body image concerns and depressions levels, as well as lower relationship satisfaction compared to postpartum women who do not endorse a history of trauma. In postpartum women with a history of trauma, higher posttraumatic stress symptoms will be associated with greater body image concerns and depression levels, and lower relationship satisfaction. We will descriptively explore levels of body image concerns, depression levels, and relationship satisfaction in postpartum women who endorse a history of sexual trauma. Proposed Analyses: Descriptive statistics will be used to characterize the sample. Correlations will evaluate the relationship between demographic variables and outcome measures. Regression or independent samples t-tests will be utilized to evaluate the hypotheses. Implications: This research has important implications for postpartum women for both their therapeutic and medical care. Findings may clarify conceptualizations of trauma and, therefore, inform treatment strategies and trauma-informed postpartum care. Additionally, results may provide further support for universal screenings during postpartum to identify women at-risk of various perinatal psychosocial concerns

Le thon : enjeux et stratégies pour l'océan Indien

Les tendances de la pêche, la transformation, et le commerce des produits thoniers sont influencés par un grand nombre de forces motrices. La pêche est fonction de la disponibilité de la ressource, de la technologie de la pêche, et des prix des intrants et des extrants. D'une manière semblable, la distribution mondiale des activités de la pêche thonière est fonction des coûts relatifs, qui sont particulièrement influencés par la disponibilité du produit brut, et le prix relatif de la main d'oeuvre. Le marché des produits thoniers est un marché mondial, et le commerce de ces produits joue un rôle important dans la détermination des prix et des quantités d'équilibre du marché de détail. La récente émergence de l'industrie de la pêche thonière dans l'océan Indien, en conjonction avec les développements dans le secteur de la transformation dans cette même région, a eu un impact important sur la distribution de la pêche et du commerce mondial du thon.

Steps in gas-surface reactions

Heterogeneous catalysis is essential to many industrial applications. These catalysts are often comprised of supported nanoparticles, which contain various different surface sites. For some reactions, the presence of specific surface sights dominates the overall reactivity. Fundamental insight into the influence of different surface sites on the surface reaction dynamics may lead to better catalyst design in the future. In this thesis, we combine ultra-high vacuum techniques and (curved) single crystal surfaces to study surface structure effects relevant to heterogeneous catalysis. We study how step edges on a platinum surface affect (elementary) reactions that occur in oxygen reduction: hydrogen dissociation, hydrogen recombination, and oxygen reduction.

Bias spectroscopy and simultaneous SET charge state detection of Si:P double dots

We report a detailed study of low-temperature (mK) transport properties of a silicon double-dot system fabricated by phosphorous ion implantation. The device under study consists of two phosphorous nanoscale islands doped to above the metal-insulator transition, separated from each other and the source and drain reservoirs by nominally undoped (intrinsic) silicon tunnel barriers. Metallic control gates, together with an Al-AlOx single-electron transistor, were positioned on the substrate surface, capacitively coupled to the buried dots. The individual double-dot charge states were probed using source-drain bias spectroscopy combined with non-invasive SET charge sensing. The system was measured in linear (VSD = 0) and non-linear (VSD 0) regimes allowing calculations of the relevant capacitances. Simultaneous detection using both SET sensing and source-drain current measurements was demonstrated, providing a valuable combination for the analysis of the system. Evolution of the triple points with applied bias was observed using both charge and current sensing. Coulomb diamonds, showing the interplay between the Coulomb charging effects of the two dots, were measured using simultaneous detection and compared with numerical simulations.Comment: 7 pages, 6 figure

Coherent electronic transfer in quantum dot systems using adiabatic passage

We describe a scheme for using an all-electrical, rapid, adiabatic population transfer between two spatially separated dots in a triple-quantum dot system. The electron spends no time in the middle dot and does not change its energy during the transfer process. Although a coherent population transfer method, this scheme may well prove useful in incoherent electronic computation (for example quantum-dot cellular automata) where it may provide a coherent advantage to an otherwise incoherent device. It can also be thought of as a limiting case of type II quantum computing, where sufficient coherence exists for a single gate operation, but not for the preservation of superpositions after the operation. We extend our analysis to the case of many intervening dots and address the issue of transporting quantum information through a multi-dot system.Comment: Replaced with (approximately) the published versio

Quantum dynamics, dissipation, and asymmetry effects in quantum dot arrays

We study the role of dissipation and structural defects on the time evolution of quantum dot arrays with mobile charges under external driving fields. These structures, proposed as quantum dot cellular automata, exhibit interesting quantum dynamics which we describe in terms of equations of motion for the density matrix. Using an open system approach, we study the role of asymmetries and the microscopic electron-phonon interaction on the general dynamical behavior of the charge distribution (polarization) of such systems. We find that the system response to the driving field is improved at low temperatures (and/or weak phonon coupling), before deteriorating as temperature and asymmetry increase. In addition to the study of the time evolution of polarization, we explore the linear entropy of the system in order to gain further insights into the competition between coherent evolution and dissipative processes.Comment: 11pages,9 figures(eps), submitted to PR

Anxiety severity and prescription medication utilization in first-time medical marijuana users

Background Anxiety and post-traumatic stress disorder (PTSD) are qualifying psychiatric conditions for medical marijuana (MM) treatment in Pennsylvania. This study examined baseline prevalence and changes in prescription anxiety medication use three months following MM treatment initiation among individuals with these qualifying conditions. Methods The study sample was comprised of 108 adults with anxiety or PTSD as a referring condition; they were enrolled in a longitudinal study evaluating biopsychosocial outcomes in new MM patients. Consenting participants completed an assessment battery at baseline and Month 3 (n = 94, 87 % follow-up rate) that included a measure of anxiety severity and questions about current anxiety medication prescription and desired (baseline) and actual (Month 3) reductions in medication use. Results Findings indicated that 59 % of participants reported prescription medications for anxiety, with 70 % reporting at least a moderate desire to reduce medication use. Overall and within the medication sub-sample, participants displayed significant reductions in anxiety severity from baseline to Month 3 (p’s \u3c0.0001). Furthermore, 32 % reported actual reductions in medication use at Month 3, and reductions were more likely among patients prescribed benzodiazepines than other drug classes. Conclusions Results suggest that a significant number of MM patients with anxiety and/or PTSD diagnoses are currently being prescribed antianxiety medications and that MM may help to reduce their use of these medications. Limitations Limitations include the observational study design and the lack of a PTSD-specific measure. More controlled longitudinal studies are necessary to better understand the role of MM in the treatment of anxiety and PTSD
