Perfusion of the interventricular septum during ventilation with positive end-expiratory pressure (PEEP)

Objective: To determine whether regional hypoperfusion of the interventricular septum occurs during ventilation with positive end-expiratory pressure. Design: Animal study. Animals: Anesthetized, closed chest dogs (n = 8). Interventions: Induction of experimental adult respiratory distress syndrome (ARDS) and then ventilation with 10,15, and 20 cm H2O of positive end-expiratory pressure. Measurements and Main Results: Cardiac output and regional interventricular septum blood flow 'were assessed at control, at induction of experimental ARDS, and at each level of positive end-expiratory pressure. Ventilation with 20 cm H2O of positive end-expiratory pressure decreased cardiac output (-32% vs. control, p <.05), and did not change absolute, but increased relative (to cardiac output) interventricular septum blood flow. During experimental ARDS and ventilation at 20 cm H2O end-expiratory pressure, there was a redistribution of flow toward the right ventricular free wall (+93%, p < .001) and the right ventricular part of the interventricular septum (+68%, p < .01), while flow to the left ventricular interventricular septum and to the left ventricular free wall remained unchanged. Locally hypoperfused interventricular septum areas or findings indicative of interventricular septum ischemia were not observed during positive end-expiratory pressure. Conclusions: The decrease in cardiac output during positive end-expiratory pressure is not caused by impaired interventricular septum blood supply. The preferential perfusion of the right ventricular interventricular septum indicates increased local right ventricular interventricular septum oxygen-demand and suggests that during positive end-expiratory pressure, this part of the interventricular septum functionally dissociates from the left ventricular interventricular septum and the left ventricular free wall to support the stressed right ventricle

“Daddies” in Controversial Memoirs and Confessions: Laurie Sandell and Sylvia Plath

Autobiographies, memoirs and confessions are widely read genres of non-fiction which have captured the attention of a wide readership for centuries. In recent decades such texts have become more open and intimate, resulting in many controversies, mainly over their fidelity to actual events. Based on an analysis of two texts dealing with the image of a father - the comics memoir The Impostor’s Daughter (2009) by contemporary artist Laurie Sandell and the confessional poem “Daddy” (written 1962, published in 1965) by Sylvia Plath (1932–1963) – this paper explores the nature of memoir, confessional writing and the main features thereof including objectivity and distancing and the emphasis on factual fidelity. Both writers developed an Electra complex and in their works they capture the changing relationships with their fathers from childhood to adulthood, their failing relationships with other men, suicide attempts, and depressions. Even though the comics memoir and confessional poetry differ on the level of genre and form, Plath and Sandell’s attitude and the depiction of their fathers follows similar patterns, as both texts cover a certain limited period of time and closely follows the influence of their fathers on the authors’ mental development

Queer Circles: Spiritualism and Role-Playing in Sarah Waters’s Affinity

This paper traces the connection between the rise of the Spiritualist Movement and feminism in the more general context of the ghosting of female identity and sexuality in Sarah Waters’s (b. 1966) lesbian romance Affinity (1999). Spiritualism is presented as a space open for transgression, where women can express their fears, desires and will for power. The role of the medium and the relationship with audience is analysed with regard to the shifting and transgression of Victorian standards of masculinity and femininity

Increasing Character Strength Knowledge, Interest, and Skill: Preliminary Evidence for a Collaborative and Multimethod Assessment Procedure

Introduction: The study’s objective was to evaluate whether a qualitative, collaborative, and multimethod assessment protocol increased reports of character strength interest, knowledge, and perceived skills. Methods: Thirty-two participants completed three phases of data collection. Participants were first screened for well-being, which was used as an auxiliary covariate to order participants into experimental conditions. Selected participants were randomly assigned to a control or collaborative and multimethod assessment (card sort × qualitative interview) condition. Participants completed pre- and post-measures of strength interest, knowledge, and perceived skill. In the final phase, second phase participants were invited to report on strength-related outcomes 24 h post-administration using an online survey. Results: A series of 2 (Assessment Condition) × 3 (Time) mixed ANOVAs were analyzed. Results revealed a significant assessment condition by time interaction for strength knowledge and perceived skill. Participants in the collaborative and multimethod assessment condition reported higher strength knowledge and perceived skills compared to control participants. These effects were maintained for 24 h. Conclusion: The findings offer preliminary yet sizable support for using collaborative and multimethod assessment procedures to increase strength knowledge and perceived skill. Because of the qualitative, collaborative, and individualized nature of our assessment protocol, the findings offer a low-cost and contextually bound pathway to increase strength-based outcomes

Covariant derivative expansion of fermionic effective action at high temperatures

We derive the fermionic contribution to the 1-loop effective action for A_4 and A_i fields at high temperatures, assuming that gluon fields are slowly varying but allowing for an arbitrary amplitude of A_4.Comment: RevTex 4, 11 pages, 3 figures.

Covariant derivative expansion of Yang-Mills effective action at high temperatures

Integrating out fast varying quantum fluctuations about Yang--Mills fields A_i and A_4, we arrive at the effective action for those fields at high temperatures. Assuming that the fields A_i and A_4 are slowly varying but that the amplitude of A_4 is arbitrary, we find a non-trivial effective gauge invariant action both in the electric and magnetic sectors. Our results can be used for studying correlation functions at high temperatures beyond the dimensional reduction approximation, as well as for estimating quantum weights of classical static configurations such as dyons.Comment: Minor changes.
