Disclosure Disconnects: Antecedents and Consequences of Disclosing Invisible Stigmas across Life Domains

Abstract: This article broadens our perspective of stigma by examining the process of disclosing an invisible stigmatized identity in work and nonwork domains. I present a model that examines the effects of individual and environmental factors on disclosure decisions across life domains. Individuals may disclose their stigma to varying degrees across life domains, and this inconsistency leads to disclosure disconnects. I examine psychological states and outcomes associated with disclosure disconnects and offer directions for future research.

For Slow Scholarship: A Feminist Politics of Resistance through Collective Action in the Neoliberal University

Abstract: The neoliberal university requires high productivity in compressed time frames. Though the neoliberal transformation of the university is well documented, the isolating effects and embodied work conditions of such increasing demands are too rarely discussed. In this article, we develop a feminist ethics of care that challenges these working conditions. Our politics foreground collective action and the contention that good scholarship requires time: to think, write, read, research, analyze, edit, organize, and resist the growing administrative and professional demands that disrupt these crucial processes of intellectual growth and personal freedom. This collectively written article explores alternatives to the fast-paced, metric-oriented neoliberal university through a slow-moving conversation on ways to slow down and claim time for slow scholarship and collective action informed by feminist politics. We examine temporal regimes of the neoliberal university and their embodied effects. We then consider strategies for slowing scholarship with the objective of contributing to the slow scholarship movement. This slowing down represents both a commitment to good scholarship, teaching, and service and a collective feminist ethics of care that challenges the accelerated time and elitism of the neoliberal university. Above all, we argue in favor of the slow scholarship movement and contribute some resistance strategies that foreground collaborative, collective, communal ways forward.

Selective transcatheter ablation of the fast and slow pathways using radiofrequency energy in patients with atrioventricular nodal reentrant tachycardia

Abstract: BACKGROUND The safety and efficacy of selective fast versus slow pathway ablation using radiofrequency energy and a transcatheter technique in patients with atrioventricular nodal reentrant tachycardia (AVNRT) were evaluated. METHODS AND RESULTS Forty-nine consecutive patients with symptomatic AVNRT were included. There were 37 women and 12 men (mean age, 43 +/- 20 years). The first 16 patients underwent a fast pathway ablation with radiofrequency current applied in the anterior/superior aspect of the tricuspid annulus. The remaining 33 patients initially had their slow pathway targeted at the posterior/inferior aspect of the right interatrial septum. The fast pathway was successfully ablated in the initial 16 patients and in three additional patients after an unsuccessful slow pathway ablation. A mean of 10 +/- 8 radiofrequency pulses were delivered; the last (successful) pulse was at a power of 24 +/- 7 W for a duration of 22 +/- 15 seconds. Four of these 19 patients developed complete atrioventricular (AV) block. In the remaining 15 patients, the post-ablation atrio-His intervals prolonged from 89 +/- 30 to 138 +/- 43 msec (p less than 0.001), whereas the shortest 1:1 AV conduction and effective refractory period of the AV node remained unchanged. Ten patients lost their ventriculoatrial (VA) conduction, and the other five had a significant prolongation of the shortest cycle length of 1:1 VA conduction (280 +/- 35 versus 468 +/- 30 msec, p less than 0.0001). Slow pathway ablation was attempted initially in 33 patients and in another two who developed uncommon AVNRT after successful fast pathway ablation. Of these 35 patients, 32 had no AVNRT inducible after 6 +/- 4 radiofrequency pulses with the last (successful) pulse given at a power of 36 +/- 12 W for a duration of 35 +/- 15 seconds. After successful slow pathway ablation, the shortest cycle length of 1:1 AV conduction prolonged from 295 +/- 44 to 332 +/- 66 msec (p less than 0.0005), the AV nodal effective refractory period increased from 232 +/- 36 to 281 +/- 61 msec (p less than 0.0001), and the atrio-His interval as well as the shortest cycle length of 1:1 VA conduction remained unchanged. No patients developed AV block. Among the last 33 patients who underwent a slow pathway ablation as the initial attempt and a fast pathway ablation only when the former failed, 32 (97%) had successful AVNRT abolition with intact AV conduction. During a mean follow-up of 6.5 +/- 3.0 months, none of the 49 patients had recurrent tachycardia. Forty patients had repeat electrophysiological studies 4-8 weeks after their successful ablation, and AVNRT could not be induced in 39 patients. CONCLUSIONS These data suggest that both fast and slow pathways can be selectively ablated for control of AVNRT: Slow pathway ablation, however, by obviating the risk of AV block, appears to be safer and should be considered as the first approach.

Mapping Abstract Complex Workflows onto Grid Environments

Abstract: In this paper we address the problem of automatically generating job workflows for the Grid. These workflows describe the execution of a complex application built from individual application components. In our work we have developed two workflow generators: the first (the Concrete Workflow Generator CWG) maps an abstract workflow defined in terms of application-level components to the set of available Grid resources. The second generator (Abstract and Concrete Workflow Generator, ACWG) takes a wider perspective and not only performs the abstract to concrete mapping but also enables the construction of the abstract workflow based on the available components. This system operates in the application domain and chooses application components based on the application metadata attributes. We describe our current ACWG based on AI planning technologies and outline how these technologies can play a crucial role in developing complex application workflows in Grid environments. Although our work is preliminary, CWG has already been used to map high energy physics applications onto the Grid. In one particular experiment, a set of production runs lasted 7 days and resulted in the generation of 167,500 events by 678 jobs. Additionally, ACWG was used to map gravitational physics workflows, with hundreds of nodes onto the available resources, resulting in 975 tasks, 1365 data transfers and 975 output files produced.
