Testing of Great Bay Oysters for Two Protozoan Pathogens

Two protozoan pathogens, Haplosporidium nelsoni (MSX) and Perkinsus marinus (Dermo) are known to be present in Great Bay oysters. With funds provided by the Piscataqua Region Estuaries Partnership (PREP), the Marine Fisheries Division of the New Hampshire Fish and Game Department (NHF&G) continues to assess the presence and intensity of both of these disease conditions in oysters from the major natural beds within the Great Bay estuarine system and at selected aquaculture sites. Histological examinations of Great Bay oysters have also revealed other endoparasites

Dysfunctional Attitudes And Vulnerability To Depression: Implications For Stress Appraisals And Coping

In recent years a number of models of depression have been developed which provide a theoretical basis for identifying factors that may increase a person\u27s risk for depression. One such model, Beck\u27s cognitive model of depression, hypothesizes that individuals who endorse a large number of dysfunctional attitudes are at risk for depression, and that the interaction of dysfunctional thinking with stressful life events results in depressive symptomatology. Using a measure of daily hassles to assess stress, the present study provided an evaluation of this proposed interaction. In addition, the stress appraisals and coping responses employed by these vulnerable individuals to a series of stressful events were compared with the responses of nonvulnerable nondepressed, and depressed individuals.;Sixty-nine women from the community completed measures of vulnerability to depression, depressive symptomatology, and life events on two occasions approximately two months apart. Measures of daily hassles, stress appraisals, and coping responses were also obtained for the four, two-week, intervals between the initial assessment and the follow-up.;Results consistent with a diathesis-stress model of depression were obtained. In addition, vulnerable individuals who reported high levels of stress tended to employ a style of coping similar to that of currently depressed individuals. This style was characterized by a lack of confidence in their ability to manage stressful events and by a reluctance to seek support from others. In contrast, the responses of vulnerable individuals with low stress more closely resembled those of nonvulnerable, nondepressed individuals.;The present study also provided a preliminary evaluation of the hypothesis that individuals whose information processing was characterized by a relatively greater accessibility of negative information would also be at risk for depression. The interaction of information accessibility with stress was examined but results failed to support this hypothesized interaction.;The present results are discussed with respect to the roles played by vulnerability, life events, stress appraisals, and coping in the etiology and maintenance of depression. Implications for future research and the treatment of depression are also discussed

Schubert's mature operas: an analytical study

This thesis examines four of Franz Schubert's complete operas: Die Zwillingsbrűder D.647, Alfonso und Estrella D.732, Die Verschworenen D.787, and Fierrabras D.796. These works date from the period of 1818-1823, sometimes referred to as Schubert's 'years of crisis'. While this period saw many changes in the composer's personal situation, it is commonly thought that he underwent a process of creative re-evaluation during these years. This was also the period of Schubert's life during which he was most seriously engaged in writing music for the stage. Thus, I argue in this thesis that it is possible to understand these operas as key works within Schubert's stylistic development. Chapter 2 of this thesis studies Adorno's 1928 critique of Schubert and draws out common themes in critical writings about the composer to do with coherence, temporality and tone. These themes are then grounded in various different types of analytical observations about Schubert's emergent style. Chapter 3 examines selected numbers from the four mature operas. Through analysing these works, we find that Schubert's developing approach to form, rhythm, musical 'signs' and other structural devices is evident. Innovations in each of these fields are understood as responses to the various dramatic challenges offered by each of the libretti. Chapter 4 summarises the conclusions of our study of the operas and suggests some possibilities for interpretation of other works which are raised by these analyses

Modular categories as representations of the 3-dimensional bordism 2-category

We show that once-extended anomalous 3-dimensional topological quantum field theories valued in the 2-category of k-linear categories are in canonical bijection with modular tensor categories equipped with a square root of the global dimension in each factor.Comment: 71 page

Risk Factors Associated with Missed Medical Appointments Among HIV-positive Young Men Who Have Sex with Men

Young men who have sex with men (YMSM) are overrepresented in the HIV epidemic in America. Retaining HIV positive YMSM in HIV care is very critical to reduce the overall burden of the HIV epidemic in America. Our study focused on identifying significant risk factors that affects retention in care for YMSM. Missing two or more medical appointments was how we measured retention in care. Using data gathered from ATN 086-106 study. This ATN cross-sectional study provided HIV positive males and females between the ages of 12 and 24 with an extensive questionnaire. The goal of this study was to analyze what risk factors are significantly associated with YMSM missing more than two or more appointments in the past 12 months. Our study found that African American and multi-racial young men were more likely to miss more than 2 appointments compared to whites. Methamphetamine, daily marijuana use, and declining mental health status caused individuals to miss multiple appointments
