    A badly wounded Marine has his life saved at the last moment, by an almost miraculous guardian angel. Articles, stories, and other compositions in this archive were written by participants in the Mighty Pen Project. The program, developed by author David L. Robbins, and in partnership with Virginia Commonwealth University and the Virginia War Memorial in Richmond, Virginia, offers veterans and their family members a customized twelve-week writing class, free of charge. The program encourages, supports, and assists participants in sharing their stories and experiences of military experience so both writer and audience may benefit

    Landau Effective Interaction between Quasiparticles in a Bose-Einstein Condensate

    Full text link
    Landau's description of the excitations in a macroscopic system in terms of quasiparticles stands out as one of the highlights in quantum physics. It provides an accurate description of otherwise prohibitively complex many-body systems, and has led to the development of several key technologies. In this paper, we investigate theoretically the Landau effective interaction between quasiparticles, so-called Bose polarons, formed by impurity particles immersed in a Bose-Einstein condensate (BEC). In the limit of weak interactions between the impurities and the BEC, we derive rigorous results for the effective interaction. They show that it can be strong even for weak impurity-boson interaction, if the transferred momentum/energy between the quasiparticles is resonant with a sound mode in the BEC. We then develop a diagrammatic scheme to calculate the effective interaction for arbitrary coupling strengths, which recovers the correct weak coupling results. Using this, we show that the Landau effective interaction in general is significantly stronger than that between quasiparticles in a Fermi gas, mainly because a BEC is more compressible than a Fermi gas. The interaction is particularly large near the unitarity limit of the impurity-boson scattering, or when the quasiparticle momentum is close to the threshold for momentum relaxation in the BEC. Finally, we show how the Landau effective interaction leads to a sizeable shift of the quasiparticle energy with increasing impurity concentration, which should be detectable with present day experimental techniques.Comment: 12 page

    Purpose: Evaluate behavior assessment and agreement among dentist, guardian, and child. Evaluate child behavior by appointment type. Methods: Patients recruited from the pediatric dental department at Virginia Commonwealth University for this convenience sample. Inclusion criteria: patients presenting for clinical exams and/or restorative treatment without the use of advanced behavior guidance between August 29, 2018, and March 7, 2019; ages 4-12-years-old; and scheduled with a single clinician. Appointments were stratified by difficulty. Behavior was assessed by dentist and caregiver using the Frankl Scale. Patient self-assessed cooperation using an age-appropriate modified Frankl Scale, developed for this study. Agreement assessed among the 3 scores at each appointment using descriptive statistics and Cohen’s Kappa. Behavior trends across appointment type assessed using Kruskal-Wallis test. SAS software (2013, Cary, NC). P-value \u3c 0.05. Results: Forty-one patient-guardian dyads enrolled in the study. Five dyads experienced multiple encounters. Demographics for the patients enrolled: 59% male; 44% Caucasian, 29% African American, 5% Asian, 2% Hispanic, 20% other/multiracial. Average patient age: 7.6 (range: 4- 12). Most patients had 1 encounter (n=36, 88%). Frankl Score agreement for provider/guardian was 79% (k=0.335), provider/child was 70% (k=0.248), and guardian/child was 81% (k=0.314). In disagreements, guardians rated behavior better than provider. Disagreement was split for provider/child and guardian/child, with the child tending to rate themselves higher, and the guardian tending to rate the child higher respectively. Marginal evidence that hard appointments resulted in poorer behaviors. Conclusion: There is fair agreement between child, guardian, and provider. In disagreements, guardians tend to rate the child’s behavior better compared to the provider and child self-assessment. Dental providers tend to be more critical of patient behavior. Marginal evidence to support harder appointments result in poorer behaviors

    Enabling the Internet White Pages Service -- the Directory Guardian

    Get PDF
    The Internet White Pages Service (IWPS) has been slow to materialise for many reasons. One of them is the security concerns that organisations have, over allowing the public to gain access to either their Intranet or their directory database. The Directory Guardian is a firewall application proxy for X.500 and LDAP protocols that is designed to alleviate these fears. Sitting in the firewall system, it filters directory protocol messages passing into and out of the Intranet, allowing security administrators to carefully control the amount of directory information that is released to the outside world. This paper describes the design of our Guardian system, and shows how relatively easy it is to configure its filtering capabilities. Finally the paper describes the working demonstration of the Guardian that was built for the 1997 World Electronic Messaging Association directory challenge. This linked the WEMA directory to the NameFLOWParadise Internet directory, and demonstrated some of the powerful filtering capabilities of the Guardian

    Governing the governors : a case study of college governance in English further education

    Get PDF
    This paper addresses the nature of governors in the governance of further education colleges in an English context (1). It explores the complex relationship between governors (people/agency), government (policy/structure) and governance (practice), in a college environment. While recent research has focused on the governance of schooling and higher education there has been little attention paid to the role of governors in the lifelong learning sector. The objective of the paper is to contribute to the debate about the purpose of college governance at a time when the Learning and Skills Council (LSC) commissioning era ends, and new government bodies responsible for further education and training, including local authorities, arrive. The paper analyses the nature of FE governance through the perspectives and experiences of governors, as colleges respond to calls from government for greater improvement and accountability in the sector (LSIS, 2009a). What constitutes creative governance is complex and controversial in the wider framework of regulation and public policy reform (Stoker, 1997; Seddon, 2008). As with other tricky concepts such as leadership, professionalism and learning, college governance is best defined in the contexts, cultures and situations in which it is located. College governance does not operate in a vacuum. It involves governors, chairs, principals, professionals, senior managers, clerks, community, business and wider agencies, including external audit and inspection regimes. Governance also acts as a prism through which national education and training reforms are mediated, at local level. While governing bodies are traditionally associated with the business of FE - steering, setting the tone and style, dealing with finance, funding, audit and procedural matters – they are increasingly being challenged to be more creative and responsive to the wider society. Drawing on a recent case study of six colleges, involving governors and key policy stakeholders, this paper explores FE governance in a fast changing policy environment

    The UPC Substituted Judgment/Best Interest Standard for Guardian Decisions: A Proposal for Reform

    Get PDF
    The introduction in 1997 of substituted judgment as a guiding principle for guardian decisions was a key contribution of the UPC to guardianship reform. The current UPC section 5-314(a) instructs guardians to consider the expressed desires and personal values of the ward when making decisions and to at all times...act in the ward\u27s best interest. This dual mandate for guardian decisions was intended to promote the self-determination interests of incapacitated adults. This article argues that in practice the standard has failed to achieve this goal. It analyzes the shortcomings of UPC Section 5-314(a) and other statutory decision-making standards and offers an improved decision-making model. Frolik and Whitton propose reform of Section 5-314(a) to provide better guidance for guardians, and to harmonize the standard for guardian decisions with other surrogate decision-making standards within the UPC
