Indirect Dissociative Recombination of LiH+^+ Molecules Fueled by Complex Resonance Manifolds

The LiH$^{+}$ molecule is prototypical of the indirect dissociative recombination (DR) process, in which a colliding electron destroys the molecule through Rydberg capture pathways. This Letter develops the first quantitative test of the Siegert state multichannel quantum defect theory description of indirect DR for a diatomic molecular ion. The R-matrix approach is adopted to calculate ab-initio quantum defects, functions of the internuclear distance that characterize both Rydberg states and the zero-energy collisions of electrons with LiH$^{+}$ ions. The calculated DR rate coefficient agrees accurately with recent experimental data (S. Krohn et al, Phys. Rev. Lett. 86, 4005). We identify the doorways to fast indirect DR as complex resonance manifolds, which couple closed channels having both high and low principal quantum numbers. This sheds new light on the competition between direct and indirect DR pathways, and suggests the reason why previous theory underestimated the DR rate by an order of magnitude.Comment: Submitted to PR

A spanning tree model for the Heegaard Floer homology of a branched double-cover

Given a diagram of a link K in S^3, we write down a Heegaard diagram for the branched-double cover Sigma(K). The generators of the associated Heegaard Floer chain complex correspond to Kauffman states of the link diagram. Using this model we make some computations of the homology \hat{HF}(Sigma(K)) as a graded group. We also conjecture the existence of a delta-grading on \hat{HF}(Sigma(K)) analogous to the delta-grading on knot Floer and Khovanov homology.Comment: 43 pages, 20 figure

How Neoliberalism Weakened Democracy in Chile

During the late twentieth century, neoliberal policy transformations were occurring in countries all over the world. In Chile, this radical change in policy removed the state from many economic spheres, which ended up hurting the Chilean people. The newly enacted neoliberal policies left the Chilean citizens in an even worse position than they had been in originally, and this suffering eroded any possibility they had of democratically participating in their government. Since the state was removing regulations with the aim of stimulating economic growth, workers were no longer promised a livable wage and they lost their opportunities to live in affordable housing. With their incomes decreasing and their expenses on the rise, they were forced to work more hours to make up the difference. Since the workers were spending more time in the factories, they had less time to be politically active. This ultimately weakened political groups tasked with holding elected officials accountable, and this caused the average Chilean citizen to become even less effective politically. Overall, free markets seem to stand in direct opposition to the idea of having a pluralistic democracy. In search of economic success, the Chilean people ended up losing their political rights, and the quality of democracy in Chile was greatly diminished

Analyzing True Self-Reliance and Individualism

This essay analyzes the story of “Rip Van Winkle” by Washington Irving and criticizes Daniel Plung’s assessment of it in his article, “Rip Van Winkle’: Metempsychosis and the Quest for Self-Reliance.” In Plung’s article, he assesses that in the story of “Rip Van Winkle,” the main character, Rip, attains self-reliance and individualism through his escape and experience on the mountain. However, although Plung’s points support his assessments, there are also many other details in the story that contradict Plung’s analysis. This essay seeks to enlighten readers to a differing interpretation of “Rip Van Winkle” by studying other details in the story

Mapping deprivation in the East Midlands - implications for policy

This paper summarises the findings from a GIS mapping analysis of deprivation at the small area level in the East Midlands using the Indices of Deprivation 2004 and identifies implications for policy in order to inform the development of the 2006 Regional Economic Strategy

Let's talk whole wellness

This article was originally published in The Prophet -- a journal created by and for the students at the Boston University School of Theology (BUSTH) to amplify the voices of STH students by promoting and sharing a range of perspectives on matters of concern including, but not limited to, spiritual practices, faith communities and society, the nature of theology, and current affairs. It serves as a platform for STH students to share their academic work, theological reflections, and life experiences with one another and the wider community

Constitutional Rhetoric

For close to a century, students of judicial behavior have suggested that what judges think is not altogether the same as what they say. Within the legal academy, this claim has long been associated with legal realists who have argued that the formal legal rules explicated in judicial opinions are at least partly epiphenomenal, masking the influence that the personal characteristics and dispositions of adjudicators exercise over legal outcomes. Political scientists have argued, variously, that such outcomes are determined by ideology, social background, or political, professional, or other institutional constraints. The notion that at least some “extralegal” factors influence judicial decision making is sufficiently intuitive and well established to be regarded as a fact. It is fair to expect, moreover, that such factors wield still greater influence in close cases of constitutional law, and particularly in cases involving constitutional rights. The outcomes of such cases are tightly bound up with deep and fundamentally divergent political commitments and social values. A vast and growing literature explores these and related issues

Clinical Management of Postpartum Hemorrhage in Community Birthing Hospitals in Vermont: A Gap Analysis to Promote Best Practice

Purpose: Despite advances in research and medical technology, the rates of postpartum hemorrhage (PPH) continue to rise. Annually, these preventable events are the cause of one-fourth of maternal deaths worldwide. In order to reduce maternal mortality and morbidity rates, the effective application of evidence-based interventions is required. The purpose of this DNP project was to conduct a gap analysis in community birthing hospitals in Vermont to examine the existing clinical management of PPH. Methods: Registered nurses at three hospitals were surveyed to assess current policies/protocols pertaining to the management of PPH in five categories: 1) systems level readiness, 2) patient level readiness, 3) recognition and prevention, 4) response, and 5) reporting and systems learning. Quality improvement recommendations targeting PPH management were made based upon the gap analysis. Results: A total of thirty-seven surveys were completed. Several evidence-based best practice recommendations were inconsistently done, not done, or unknown. Nurses would feel more prepared to manage a postpartum hemorrhage with more simulation drills and mock codes, a walk-through of mass transfusion protocols, easy access to hemorrhage medications, a PPH risk assessment done on all laboring mothers upon admission, and education about identification of PPH. Conclusions: Areas for improvement were identified across all five categories. A systematic approach to evaluation of current practice protocols and identification of improvement targets with implementation strategies using the California Maternal Quality Care Collaborative (CMQCC) OB Hemorrhage Toolkit V2.0 may enhance clinical management of PPH and maternity outcomes
