In nature, repeated base units produce handed structures that selectively bond to make rigid or compliant materials. Auxetic tilings are scale-independent frameworks made from repeated unit cells that expand under tension. We discovered how to produce handedness in auxetic unit cells that shear as they expand by changing the symmetries and alignments of auxetic tilings. Using the symmetry and alignment rules that we developed, we made handed shearing auxetics that tile planes, cylinders, and spheres. By compositing the handed shearing auxetics in a manner inspired by keratin and collagen, we produce both compliant structures that expand while twisting and deployable structures that can rigidly lock. This work opens up new possibilities in designing chemical frameworks, medical devices like stents, robotic systems, and deployable engineering structures.

Engaging social work practitioners in research: challenges and opportunities.

Contemporary emphasis on measuring and evaluating observable, behavioral outcomes reflects a major change in the profession toward greater empirical basis for social work practice. This intellectual and methodological shift has created a gap between practitioners and researchers. While social work practitioners definitely should be more knowledgeable and receptive to interventions that have proven to be effective in helping people, social work academics must pay more attention to the realities of social work practitioners who struggle daily with expanding caseloads, ever-increasing time pressures to help clients whose lives are embedded in poverty, unemployment, oppression, racism, homelessness, and violence.

Stepping Up: Empowering Science Communicators at UW's College of the Environment

Meyer, J. J.; Graumlich, L. J.; McCarthy, M. M.

2017-12-01

At the University of Washington's College of the Environment, we strive to expand the reach of our science through better communication. While sharing science broadly is often handled through a press office, there are other avenues for disseminating research results that impact society. By empowering scientists to speak authentically about their work and why it matters, we can daylight new outlets and connections where their work can create change in our world. Scientists are experts at sharing their findings with peers, yet available pathways to reaching broader audiences can often be a black box. On the advice of a Science Communication Task Force and guided by college leadership, we launched a science communication program in 2014 as a vehicle to assist our researchers. Whether the goal is to increase public appreciation for science or help shape natural resource policy, we provide support to amplify the impact of our scientist's work. This includes events and networking opportunities, trainings and workshops, one-on-one coaching and consulting, and making connections to outlets where their work can have impact. We continue to refine and expand our program, striking a balance between creating a solid foundation of best communication practices while offering resources to address current needs of the day. We will share the successes and challenges of our program and demonstrate how our model can be implemented at other institutions.

Authentic leaders creating healthy work environments for nursing practice.

PubMed

Shirey, Maria R

2006-05-01

Implementation of authentic leadership can affect not only the nursing workforce and the profession but the healthcare delivery system and society as a whole. Creating a healthy work environment for nursing practice is crucial to maintain an adequate nursing workforce; the stressful nature of the profession often leads to burnout, disability, and high absenteeism and ultimately contributes to the escalating shortage of nurses. Leaders play a pivotal role in retention of nurses by shaping the healthcare practice environment to produce quality outcomes for staff nurses and patients. Few guidelines are available, however, for creating and sustaining the critical elements of a healthy work environment. In 2005, the American Association of Critical-Care Nurses released a landmark publication specifying 6 standards (skilled communication, true collaboration, effective decision making, appropriate staffing, meaningful recognition, and authentic leadership) necessary to establish and sustain healthy work environments in healthcare. Authentic leadership was described as the "glue" needed to hold together a healthy work environment. Now, the roles and relationships of authentic leaders in the healthy work environment are clarified as follows: An expanded definition of authentic leadership and its attributes (eg, genuineness, trustworthiness, reliability, compassion, and believability) is presented. Mechanisms by which authentic leaders can create healthy work environments for practice (eg, engaging employees in the work environment to promote positive behaviors) are described. A practical guide on how to become an authentic leader is advanced. A research agenda to advance the study of authentic leadership in nursing practice through collaboration between nursing and business is proposed.

Creation of mass dimension one fermionic particles in asymptotically expanding universe

NASA Astrophysics Data System (ADS)

Pereira, S. H.; Lima, Rodrigo C.

In the present work we study the process of particle creation for mass dimension one fermionic fields (sometimes named Elko) as a consequence of expansion of the universe. We study the effect driven by an expanding background that is asymptotically Minkowski in the past and future. The differential equation that governs the time mode function is obtained for the conformal coupling case and, although its solution is nonanalytic, within an approximation that preserves the characteristics of the terms that break analyticity, analytic solutions are obtained. Thus, by means of Bogolyubov transformations technique, the number density of particles created is obtained, which can be compared to exact solutions already present in literature for scalar and Dirac particles. The spectrum of the created particles was obtained and it was found that it is a generalization of the scalar field case, which converges to the scalar field one when the specific terms concerning the Elko field are dropped out. We also found that lighter Elko particles are created in larger quantities than the Dirac fermionic particles. By considering the Elko particles as candidate to the dark matter in the universe, such result shows that there are more light dark matter (Elko) particles created by the gravitational effects in the universe than baryonic (fermionic) matter, in agreement to the standard model.

Creating a library holding group: an approach to large system integration.

Faced with resource constraints, many hospital libraries have considered joint operations. This case study describes how Providence Health & Services created a single group to provide library services. Using a holding group model, staff worked to unify more than 6,100 nonlibrary subscriptions and 14 internal library sites. Our library services grew by unifying 2,138 nonlibrary subscriptions and 11 library sites and hiring more library staff. We expanded access to 26,018 more patrons. A model with built-in flexibility allowed successful library expansion. Although challenges remain, this success points to a viable model of unified operations.

To reduce racial and ethnic disparities in diabetes care and outcomes, it is critical to integrate health care and community approaches. However, little work describes how to expand and sustain such partnerships and initiatives. We outline our experience creating and growing an initiative to improve diabetes care and outcomes in the predominantly African American South Side of Chicago. Our project involves patient education and activation, a quality improvement collaborative with six clinics, provider education, and community partnerships. We aligned our project with the needs and goals of community residents and organizations, the mission and strategic plan of our academic medical center, various strengths and resources in Chicago, and the changing health care marketplace. We use the Robert Wood Johnson Foundation Finding Answers: Disparities Research for Change conceptual model and the Consolidated Framework for Implementation Research to elucidate how we expanded and sustained our project within a shifting environment. We recommend taking action to integrate health care with community projects, being inclusive, building partnerships, working with the media, and understanding vital historical, political, and economic contexts. © 2014 Society for Public Health Education.

Serhal, Eva; Arena, Amanda; Sockalingam, Sanjeev; Mohri, Linda; Crawford, Allison

2018-03-01

The Project Extension for Community Healthcare Outcomes (ECHO) model expands primary care provider (PCP) capacity to manage complex diseases by sharing knowledge, disseminating best practices, and building a community of practice. The model has expanded rapidly, with over 140 ECHO projects currently established globally. We have used validated implementation frameworks, such as Damschroder's (2009) Consolidated Framework for Implementation Research (CFIR) and Proctor's (2011) taxonomy of implementation outcomes, combined with implementation experience to (1) create a set of questions to assess organizational readiness and suitability of the ECHO model and (2) provide those who have determined ECHO is the correct model with a checklist to support successful implementation. A set of considerations was created, which adapted and consolidated CFIR constructs to create ECHO-specific organizational readiness questions, as well as a process guide for implementation. Each consideration was mapped onto Proctor's (2011) implementation outcomes, and questions relating to the constructs were developed and reviewed for clarity. The Preimplementation list included 20 questions; most questions fall within Proctor's (2001) implementation outcome domains of "Appropriateness" and "Acceptability." The Process Checklist is a 26-item checklist to help launch an ECHO project; items map onto the constructs of Planning, Engaging, Executing, Reflecting, and Evaluating. Given that fidelity to the ECHO model is associated with robust outcomes, effective implementation is critical. These tools will enable programs to work through key considerations to implement a successful Project ECHO. Next steps will include validation with a diverse sample of ECHO projects.This is an open-access article distributed under the terms of the Creative Commons Attribution-Non Commercial-No Derivatives License 4.0 (CCBY-NC-ND), where it is permissible to download and share the work provided it is properly cited.

The Center for Expanded Data Annotation and Retrieval is studying the creation of comprehensive and expressive metadata for biomedical datasets to facilitate data discovery, data interpretation, and data reuse. We take advantage of emerging community-based standard templates for describing different kinds of biomedical datasets, and we investigate the use of computational techniques to help investigators to assemble templates and to fill in their values. We are creating a repository of metadata from which we plan to identify metadata patterns that will drive predictive data entry when filling in metadata templates. The metadata repository not only will capture annotations specified when experimental datasets are initially created, but also will incorporate links to the published literature, including secondary analyses and possible refinements or retractions of experimental interpretations. By working initially with the Human Immunology Project Consortium and the developers of the ImmPort data repository, we are developing and evaluating an end-to-end solution to the problems of metadata authoring and management that will generalize to other data-management environments.

Mechanical Interaction of an Expanding Coiled Stent with a Plaque-Containing Arterial Wall: A Finite Element Analysis.

PubMed

Welch, Tré R; Eberhart, Robert C; Banerjee, Subhash; Chuong, Cheng-Jen

2016-03-01

Wall injury is observed during stent expansion within atherosclerotic arteries, related in part to stimulation of the inflammatory process. Wall stress and strain induced by stent expansion can be closely examined by finite element analysis (FEA), thus shedding light on procedure-induced sources of inflammation. The purpose of this work was to use FEA to examine the interaction of a coiled polymer stent with a plaque-containing arterial wall during stent expansion. An asymmetric fibrotic plaque-containing arterial wall model was created from intravascular ultrasound (IVUS) images of a diseased artery. A 3D model for a coil stent at unexpanded state was generated in SolidWorks. They were imported into ANSYS for FEA of combined stent expansion and fibrotic plaque-distortion. We simulated the stent expansion in the plaqued lumen by increasing balloon pressure from 0 to 12 atm in 1 atm step. At increasing pressure, we examined how the expanding stent exerts forces on the fibrotic plaque and vascular wall components, and how the latter collectively resist and balance the expansive forces from the stent. Results show the expanding coiled stent creates high stresses within the plaque and the surrounding fibrotic capsule. Lower stresses were observed in adjacent medial and adventitial layers. High principal strains were observed in plaque and fibrotic capsule. The results suggest fibrotic capsule rupture might occur at localized regions. The FEA/IVUS method can be adapted for routine examination of the effects of the expansion of selected furled stents against IVUS-reconstructed diseased vessels, to improve stent deployment practices.

Adiabatic Expansion of Electron Gas in a Magnetic Nozzle.

PubMed

Takahashi, Kazunori; Charles, Christine; Boswell, Rod; Ando, Akira

2018-01-26

A specially constructed experiment shows the near perfect adiabatic expansion of an ideal electron gas resulting in a polytropic index greater than 1.4, approaching the adiabatic value of 5/3, when removing electric fields from the system, while the polytropic index close to unity is observed when the electrons are trapped by the electric fields. The measurements were made on collisionless electrons in an argon plasma expanding in a magnetic nozzle. The collision lengths of all electron collision processes are greater than the scale length of the expansion, meaning the system cannot be in thermodynamic equilibrium, yet thermodynamic concepts can be used, with caution, in explaining the results. In particular, a Lorentz force, created by inhomogeneities in the radial plasma density, does work on the expanding magnetic field, reducing the internal energy of the electron gas that behaves as an adiabatically expanding ideal gas.

Female artists and the VR crucible: expanding the aesthetic vocabulary

NASA Astrophysics Data System (ADS)

Morie, Jacquelyn Ford

2012-03-01

Virtual Reality was a technological wonder in its early days, and it was widely held to be a domain where men were the main practitioners. However, a survey done in 2007 of VR Artworks (Immersive Virtual Environments or VEs) showed that women have actually created the majority of artistic immersive works. This argues against the popular idea that the field has been totally dominated by men. While men have made great contributions in advancing the field, especially technologically, it appears most artistic works emerge from a decidedly feminine approach. Such an approach seems well suited to immersive environments as it incorporates aspects of inclusion, wholeness, and a blending of the body and the spirit. Female attention to holistic concerns fits the gestalt approach needed to create in a fully functional yet open-ended virtual world, which focuses not so much on producing a finished object (like a text or a sculpture) but rather on creating a possibility for becoming, like bringing a child into the world. Immersive VEs are not objective works of art to be hung on a wall and critiqued. They are vehicles for experience, vessels to live within for a piece of time.

Expanding P450 catalytic reaction space through evolution and engineering

McIntosh, John A.; Farwell, Christopher C.; Arnold, Frances H.

2014-01-01

Advances in protein and metabolic engineering have led to wider use of enzymes to synthesize important molecules. However, many desirable transformations are not catalyzed by any known enzyme, driving interest in understanding how new enzymes can be created. The cytochrome P450 enzyme family, whose members participate in xenobiotic metabolism and natural products biosynthesis, catalyzes an impressive range of difficult chemical reactions that continues to grow as new enzymes are characterized. Recent work has revealed that P450-derived enzymes can also catalyze useful reactions previously accessible only to synthetic chemistry. The evolution and engineering of these enzymes provides an excellent case study for how to genetically encode new chemistry and expand biology’s reaction space. PMID:24658056

Revealing Risks in Adaptation Planning: expanding Uncertainty Treatment and dealing with Large Projection Ensembles during Planning Scenario development

Brekke, L. D.; Clark, M. P.; Gutmann, E. D.; Wood, A.; Mizukami, N.; Mendoza, P. A.; Rasmussen, R.; Ikeda, K.; Pruitt, T.; Arnold, J. R.; Rajagopalan, B.

2015-12-01

Adaptation planning assessments often rely on single methods for climate projection downscaling and hydrologic analysis, do not reveal uncertainties from associated method choices, and thus likely produce overly confident decision-support information. Recent work by the authors has highlighted this issue by identifying strengths and weaknesses of widely applied methods for downscaling climate projections and assessing hydrologic impacts. This work has shown that many of the methodological choices made can alter the magnitude, and even the sign of the climate change signal. Such results motivate consideration of both sources of method uncertainty within an impacts assessment. Consequently, the authors have pursued development of improved downscaling techniques spanning a range of method classes (quasi-dynamical and circulation-based statistical methods) and developed approaches to better account for hydrologic analysis uncertainty (multi-model; regional parameter estimation under forcing uncertainty). This presentation summarizes progress in the development of these methods, as well as implications of pursuing these developments. First, having access to these methods creates an opportunity to better reveal impacts uncertainty through multi-method ensembles, expanding on present-practice ensembles which are often based only on emissions scenarios and GCM choices. Second, such expansion of uncertainty treatment combined with an ever-expanding wealth of global climate projection information creates a challenge of how to use such a large ensemble for local adaptation planning. To address this challenge, the authors are evaluating methods for ensemble selection (considering the principles of fidelity, diversity and sensitivity) that is compatible with present-practice approaches for abstracting change scenarios from any "ensemble of opportunity". Early examples from this development will also be presented.

I have been working on a project to further our understanding of orbital debris by helping create a new dataset previously too complex to be implemented in past orbital debris propagation models. I am doing this by creating documentation and 3D examples and illustrations of the shape categories. Earlier models assumed all orbital debris to be spherical aluminum fragments. My project will help expand our knowledge of shape populations to 6 categories: Straight Needle/Rod/Cylinder, Bent Needle/Rod/Cylinder, Flat Plate, Bent Plate, Nugget/Parallelepiped/Spheroid, and Flexible. The last category, Flexible, is still up for discussion and may be modified. These categories will be used to characterize fragments in the DebriSat experiment.

We propose for social scientists a theoretical toolbox containing a set of motivations that neurobiologists have recently validated. We show how these motivations can be used to create a theory of society recognizably similar to existing stable societies (sustainable, self-reproducing, and largely peaceful). Using this toolbox, we describe society in terms of three institutions: economy (a source of sustainability), government (peace), and the family (reproducibility). Conducting a thought experiment in three parts, we begin with a simple theory with only two motivations. We then create successive theories that systematically add motivations, showing that each element in the toolbox makes its own contribution to explain the workings of a stable society and that the family has a critical role in this process.

This paper is based on a study of Revista Trimestral Micrografica (Trabajos del Laboratorio de Investigaciones Biologicas) between its creation by Santiago Ramon y Cajal in 1896 and his death in 1934. The journal Revista Trimestral Micrografica was the main way in which Santiago Ramon y Cajal and his school published their work since its creation. Ramon y Cajal created the journal for two main reasons: first, he needed a rapid system to publish his own work; second, the journal could serve to encourage his pupils. The journal published many important reports defending the neuronal theory which expanded the cellular one to include the nervous system.

Military culture and workplace are areas of interest for researchers across disciplines. However, few publications on military culture exist. The purpose of this article is to introduce general concepts regarding the structure and culture of the United States Military and discuss how this creates challenges for reintegrating into the civilian world. Topics that will be covered in this article include an overview of the Department of Defense (DoD) and Department of Veterans Affairs (VA), socialization to military culture, the unique features of the military as a workplace, the cultural experiences of military personnel reintegrating back into the community, and the challenges faced by military members and their spouses. The provided information on military culture will expand military cultural competency so that civilian employers can enhance their ability to create supportive workplaces for veterans and military spouses during times of transition and reintegration. The unique characteristics of the military culture should be understood by those who work with or plan to work with military populations.

Temporomandibular Disorders (TMD) represent a particular form of chronic pain that, while not outwardly debilitating, profoundly impacts interactions as fundamental to human existence as smiling, laughing, speaking, eating, and intimacy. Our analysis, informed by an expanded “works of illness” assessment, draws attention to work surrounding social and physical risk. We refer to these as the work of stoicism and the work of vigilance and identify double binds created in contexts that call for both. Conflicting authorial stances in informants’ narratives are shown to be essential in maintaining a positive identity in the face of illness. While earlier ethnographic studies report TMD sufferers’ experience of stigma and search for diagnosis and legitimacy, we present a group of individuals who have accepted diagnosis at face value and soldier through pain as a fundamental aspect of their identity.

The energy-release rate and “self-force” of dynamically expanding spherical and plane inclusion boundaries with dilatational eigenstrain

NASA Astrophysics Data System (ADS)

Markenscoff, Xanthippi; Ni, Luqun

2010-01-01

In the context of the linear theory of elasticity with eigenstrains, the radiated field including inertia effects of a spherical inclusion with dilatational eigenstrain radially expanding is obtained on the basis of the dynamic Green's function, and one of the half-space inclusion boundary (with dilatational eigenstrain) moving from rest in general subsonic motion is obtained by a limiting process from the spherically expanding inclusion as the radius tends to infinity while the eigenstrain remains constrained, and this is the minimum energy solution. The global energy-release rate required to move the plane inclusion boundary and to create an incremental region of eigenstrain is defined analogously to the one for moving cracks and dislocations and represents the mechanical rate of work needed to be provide for the expansion of the inclusion. The calculated value, which is the "self-force" of the expanding inclusion, has a static component plus a dynamic one depending only on the current value of the velocity, while in the case of the spherical boundary, there is an additional contribution accounting for the jump in the strain at the farthest part at the back of the inclusion having the time to reach the front boundary, thus making the dynamic "self-force" history dependent.

Insufficient biomechanical data exist from comparisons of the stability of expandable lateral cages with that of static transforaminal lumbar interbody fusion (TLIF) cages. The purpose of this biomechanical study was to compare the relative rigidity of L4-5 expandable lateral interbody constructs with or without additive pedicle screw fixation with that of L4-5 static TLIF cages in a novel cadaveric spondylolisthesis model. Eight human cadaver spines were used in this study. A spondylolisthesis model was created at the L4-5 level by creating 2 injuries. First, in each cadaver, a nucleotomy from 2 channels through the anterior side was created. Second, the cartilage of the facet joint was burred down to create a gap of 4 mm. Light-emitting-diode tracking markers were placed at L-3, L-4, L-5, and S-1. Specimens were tested in the following scenarios: intact model, bilateral pedicle screws, expandable lateral 18-mm-wide cage (alone, with unilateral pedicle screws [UPSs], and with bilateral pedicle screws [BPSs]), expandable lateral 22-mm-wide cage (alone, with UPSs, and with BPSs), and TLIF (alone, with UPSs, and with BPSs). Four of the spines were tested with the expandable lateral cages (18-mm cage followed by the 22-mm cage), and 4 of the spines were tested with the TLIF construct. All these constructs were tested in flexion-extension, axial rotation, and lateral bending. The TLIF-alone construct was significantly less stable than the 18- and 22-mm-wide lateral lumbar interbody fusion (LLIF) constructs and the TLIF constructs with either UPSs or BPSs. The LLIF constructs alone were significantly less stable than the TLIF construct with BPSs. However, there was no significant difference between the 18-mm LLIF construct with UPSs and the TLIF construct with BPSs in any of the loading modes. Expandable lateral cages with UPSs provide stability equivalent to that of a TLIF construct with BPSs in a degenerative spondylolisthesis model.

Prayer as therapeutic process toward transforming destructiveness within a spiritual direction relationship.

Kuchan, Karen L

2011-03-01

This article will expand previous conceptualizations (Kuchan, Presence Int J Spiritual Dir 12(4):22-34, 2006; J Religion Health 47(2):263-275, 2008; J Pastoral Care Counsel, forthcoming) of what might be occurring during a prayer practice that creates space within a spiritual direction relationship for the creation of inner images that reveal a person's unconscious relational longings and co-created representations of God that seem to facilitate therapeutic process toward aliveness. In previous articles, I suggest one way to understand the prayer experience is through a lens of Winnicottian notions of transitional space, illusion, and co-creation of God images. This article expands on these ideas to include an understanding of God as Objective Other (Lewis, The four loves, 1960) interacting with a part of a person's self (Jung, in: The structure and dynamics of the psyche, collected works 8, 1934; Symington, Narcissism, a new theory, 1993) that has capacity for subjectivity (Benjamin, Like subjects, love objects: Essays on recognition and sexual difference, 1995) and co-creation (Winnicott, Home is where we start from: Essays by a psychoanalyst, 1990), of inner representations of God (Ulanov, Winnicott, god and psychic reality, 2001). I also expand on a notion of God as "Source of aliveness" by integrating an aspect of how Symington (Narcissism, a new theory, 1993) thinks about "the lifegiver," which he understands to be a mental object. After offering this theoretical expansion of the prayer practice/experience, one woman's inner representations of self and God are reflected upon in terms of a therapeutic process toward transforming destructiveness, utilizing ideas from Winnicott, Kohut, and Benjamin.

Creating value in health care through big data: opportunities and policy implications.

Roski, Joachim; Bo-Linn, George W; Andrews, Timothy A

2014-07-01

Big data has the potential to create significant value in health care by improving outcomes while lowering costs. Big data's defining features include the ability to handle massive data volume and variety at high velocity. New, flexible, and easily expandable information technology (IT) infrastructure, including so-called data lakes and cloud data storage and management solutions, make big-data analytics possible. However, most health IT systems still rely on data warehouse structures. Without the right IT infrastructure, analytic tools, visualization approaches, work flows, and interfaces, the insights provided by big data are likely to be limited. Big data's success in creating value in the health care sector may require changes in current polices to balance the potential societal benefits of big-data approaches and the protection of patients' confidentiality. Other policy implications of using big data are that many current practices and policies related to data use, access, sharing, privacy, and stewardship need to be revised.

Stress and displacement pattern evaluation using two different palatal expanders in unilateral cleft lip and palate: a three-dimensional finite element analysis.

PubMed

Mathew, Anoop; Nagachandran, K S; Vijayalakshmi, Devaki

2016-12-01

In this finite element (FE) study, the stress distribution and displacement pattern was evaluated in the mid-palatal area and around circum-maxillary sutures exerted by bone-borne palatal expander (BBPE) in comparison with conventional HYRAX rapid palatal expander in unilateral cleft lip and palate. Computed tomography scan images of a patient with unilateral cleft palate was used to create a FE model of the maxillary bone along with circum-maxillary sutures. A three-dimensional model of the conventional HYRAX (Hygienic Rapid Expander) expander and custom-made BBPE was created by laser scanning and programmed into the FE model. With the BBPE, the maximum stress was observed at the implant insertion site, whereas with the conventional HYRAX expander, it was at the dentition level. Among the circum-maxillary sutures, the zygomaticomaxillary suture experienced maximum stress followed by the zygomaticotemporal and nasomaxillary sutures. Displacement in the X-axis (transverse) was highest on the cleft side, and in the Y-axis (antero-posterior), it was highest in the posterior region in the BBPE. The total displacement was observed maximum in the mid-palatal cleft area in the BBPE, and it produced true skeletal expansion at the alveolar level without any dental tipping when compared with the conventional HYRAX expander.

The deaths and diseases of slaves in the São Paulo State sugarcane municipality of Capivari are addressed, associating the causes attributed to these deaths to the social and economic context and characteristics of the local slave communities. The impact of malaria, relating it to the age brackets, the environment created by work on the sugarcane plantations and the evolution of the occupation of the area, initially by expanding frontiers, is emphasized. The relationship between illness and work processes, as well as the post-disembarkation mortality of Africans and the possibility of mortality crises among the sugarcane captives is explored. The results lead to a discussion of the impact of habitat and Atlantic displacement and the difficulty in acclimatizing.

Working to Full Scope: The Reorganization of Nursing Work in Two Canadian Community Hospitals

2018-01-01

Work relationships between registered nurses (RNs) and practical nurses (LPNs) are changing as new models of nursing care delivery are introduced to create more flexibility for employers. In Canada, a team-based, hospital nursing care delivery model, known as Care Delivery Model Redesign (CDMR), redesigned a predominantly RN-based staffing model to a functional team consisting of fewer RNs and more LPNs. The scope of practice for LPNs was expanded, and unregulated health care assistants introduced. This study began from the standpoint of RNs and LPNs to understand their experiences working on redesigned teams by focusing on discourses activated in social settings. Guided by institutional ethnography, the conceptual and textual resources nurses are drawing on to understand these changing work relationships are explicated. We show how the institutional goals embedded in CDMR not only mediate how nurses work together, but how they subordinate holistic standards of nursing toward fragmented, task-oriented, divisions of care.

An efficient nonlinear Feshbach engine

Li, Jing; Fogarty, Thomás; Campbell, Steve; Chen, Xi; Busch, Thomas

2018-01-01

We investigate a thermodynamic cycle using a Bose-Einstein condensate (BEC) with nonlinear interactions as the working medium. Exploiting Feshbach resonances to change the interaction strength of the BEC allows us to produce work by expanding and compressing the gas. To ensure a large power output from this engine these strokes must be performed on a short timescale, however such non-adiabatic strokes can create irreversible work which degrades the engine’s efficiency. To combat this, we design a shortcut to adiabaticity which can achieve an adiabatic-like evolution within a finite time, therefore significantly reducing the out-of-equilibrium excitations in the BEC. We investigate the effect of the shortcut to adiabaticity on the efficiency and power output of the engine and show that the tunable nonlinearity strength, modulated by Feshbach resonances, serves as a useful tool to enhance the system’s performance.

Accelerating medical innovation at USC: realizing the dream of Alfred E. Mann.

2012-07-01

Alfred E. Mann's vision is to create organizations that will help medical innovations born in academic environments evolve into commercially fit solutions, without the risk of being abandoned under the financial pressures early stage start-ups often experience. In 1998, Mann worked with Stephen Sample, president of USC, to create the first AMI for Biomedical Engineering, an organization fueled by an endowment valued at approximately US$160 million today. Technology-acceleration centers come in different flavors. AMI USC's recipe has evolved since its creation, with edits that incorporate lessons learned and improvements brought by its expanding network of talented resource people. Its 15-member staff, consisting of three-fourths industry professionals, includes seasoned generalists and specialists in medical technology commercialization. Although the support varies with each invention, some recurring ingredients weave into the AMI approach to accelerating medical innovation.

Personal care assistants' experiences of caring for people on home mechanical ventilation.

PubMed

Israelsson-Skogsberg, Åsa; Lindahl, Berit

2017-03-01

The aim of this study was to describe personal care assistants' (PCA) experiences of working with a ventilator-assisted person at home. Data were collected from fifteen audiotaped semistructured interviews with PCAs supporting a child or adult using home mechanical ventilation (HMV). Thirteen women and two men participated; their working experience with HMV users ranged from one to 17 years (median 6 years). Data were subjected to qualitative content analysis in an inductive and interpretive manner. Five categories emerged from the data: Being part of a complex work situation; Taking on a multidimensional responsibility; Caring carried out in someone's home; Creating boundaries in an environment with indistinct limits; and Being close to another's body and soul. The participants felt very close to the person they worked with, both physically and emotionally. They had a great responsibility and therefore a commensurate need for support, guidance and a well-functioning organisation around the HMV user. There is international consensus that advanced home care will continue to expand and personal care assistance is key in this development. We suggest that one way to move forward for PCAs working with HMV users is to create multiprofessional teams led by a key-person who coordinates the individual needs. More research is needed within this area from a broad perspective including the HMV-assisted persons, relatives, personal care assistants and management organisations. © 2016 Nordic College of Caring Science.

Kumar, Sanjay

2003-10-01

This article presents an overview of selective laser sintering (SLS) work as reported in various journals and proceedings. Selective laser sintering was first done mainly on polymers and nylon to create prototypes for audio-visual help and fit-to-form tests. Gradually it was expanded to include metals and alloys to manufacture functional prototypes and develop rapid tooling. The growth gained momentum with the entry of commercial entities such as DTM Corporation and EOS GmbH Electro Optical Systems. Computational modeling has been used to understand the SLS process, optimize the process parameters, and enhance the efficiency of the sintering machine.

This review explores Archer, Dawson, Seakins, and Wong's "Disorienting, fun or meaningful? Disadvantaged families' experiences of a science museum visit" by examining the analytic frameworks guiding this study. To expand on Archer et al.'s use of feminist post-structuralist theories of identity we draw from the theory of intersectionality to provide a more robust framework for analyzing barriers to engagement within an informal learning space. Our response to this work ends by exploring the types of solutions generated from an intersectionality framework—solutions aimed at transforming institutional programs and practices to create more equitable spaces for learning.

Parts plus pipes: synthetic biology approaches to metabolic engineering

Boyle, Patrick M.; Silver, Pamela A.

2011-01-01

Synthetic biologists combine modular biological “parts” to create higher-order devices. Metabolic engineers construct biological “pipes” by optimizing the microbial conversion of basic substrates to desired compounds. Many scientists work at the intersection of these two philosophies, employing synthetic devices to enhance metabolic engineering efforts. These integrated approaches promise to do more than simply improve product yields; they can expand the array of products that are tractable to produce biologically. In this review, we explore the application of synthetic biology techniques to next-generation metabolic engineering challenges, as well as the emerging engineering principles for biological design.

2016-09-01

To test the effort-reward imbalance model among older nurses, expanding it to include the moderation of overcommitment and age in the stress-health complaints relationship, mediated by organisational injustice. The theoretical framework included the effort-reward imbalance, the uncertainty management and the socio-emotional selectivity models. Employing a two-wave design, the participants were 255 nurses aged 45 years and over, recruited from four large hospitals in Spain (Madrid and Basque Country). The direct effect of imbalance on health complaints was supported: it was significant when overcommitment was low but not when it was high. Organisational injustice mediated the influence of effort-reward imbalance on health complaints. The conditional effect of the mediation of organisational injustice was significant in three of the overcommitment/age conditions but it weakened, becoming non-significant, when the level of overcommitment was low and age was high. The study tested the model in nursing populations and expanded it to the settings of occupational health and safety at work. The results of this study highlight the importance of effort-reward imbalance and organisational justice for creating healthy work environments. © 2016 John Wiley & Sons Ltd.

The global practice of drug development is expanding into many different continents and countries. India, in particular, is rapidly emerging as an economic force in this arena by offering ever-expanding opportunities for pharmaceutical market expansion as well as productive drug development partnerships. The key to the country's current socioeconomic success appears to be education, particularly the development of higher and professional education. Also, recent modifications to India's patent laws offer greater protections and incentives for international investment. Increasing numbers of competent contract research organizations create attractive opportunities for large Western pharmaceutical companies with a desire to gain access to burgeoning markets as well as mitigate the rising cost of drug development with less costly services. Well-trained veterinary pathologists are available, appropriate facilities are being constructed, and laboratory capabilities are expanding. Developing a productive partnership with a credible laboratory service in India, as with any new provider, requires due diligence and knowledgeable scrutiny of key elements of the work stream, such as facilities, education and training of laboratory personnel, Good Laboratory Practices, animal care, timelines, and data management. Ultimately and with appropriate management, mutually beneficial drug development partnerships are available in India.

2018-07-01

The present research expands upon previous theory and empirical work concerning the leadership-health link by examining the lagged effects of leader identity entrepreneurship (i.e., leaders' creation of a sense of "we" and "us" among team members) on team members' burnout, work engagement and turnover intentions. We report results from a 2-wave field study with employees from a large solar panel producing organization in China conducted over a 10-month period. Findings indicate that perceived leader identity entrepreneurship predicted greater subsequent work engagement among team members, as well as lower subsequent burnout and turnover intentions. Moreover, effects on reduced turnover intentions were mediated by reduced burnout and increased work engagement. These findings are the first to examine how leader identity entrepreneurship impacts subsequent employee health and turnover intentions and suggest that leaders help to promote health and well-being in the workplace by creating and developing a sense of shared identity among those they lead.

The formation of expanded austenite in Cr-Ni austenitic stainless steels like AISI 316L is not completely understood despite its technological relevance. In this work, we present an in-situ X-ray diffraction study on the growth kinetics of the expanded austenite. We applied a low-temperature nitrocarburizing treatment using a mixture of NH3, N2, H2, and C2H4 gases at atmospheric pressures in a novel and custom built chamber attached to a Bruker D8 Advance diffractometer. The nitrocarburizing temperature was varied between 340 and 440 °C, and the possible effects of the gas amount were also tested. The thickness of the growing layer was determined from the shrinkage of the unmodified austenite peak. The growth rate coefficient was calculated using the linear-parabolic equation. The resulting coefficients follow the Arrhenius law with the activation energy of 165 ± 12 kJ/mol. This value is in good agreement with the diffusion activation energy for heavy interstitials like carbon and nitrogen. The expanded austenite peak was modelled by a multilayer approach, where each 0.5 μm sublayer has a constant lattice parameter. The lattice expansion is analyzed as a function of the Boltzmann-variable (η = 0.5 × t-1/2). The expanded austenite layer in this metric has a constant width. Furthermore by rescaling with the lattice expansion of the first sublayer, it is possible to create a scale-independent master curve. These findings indicate that thickening of the expanded austenite is purely diffusion controlled, while the extent of strain is set by the uptake rate of the gas atoms.

Mathematical model of an air-filled alpha stirling refrigerator

NASA Astrophysics Data System (ADS)

McFarlane, Patrick; Semperlotti, Fabio; Sen, Mihir

2013-10-01

This work develops a mathematical model for an alpha Stirling refrigerator with air as the working fluid and will be useful in optimizing the mechanical design of these machines. Two pistons cyclically compress and expand air while moving sinusoidally in separate chambers connected by a regenerator, thus creating a temperature difference across the system. A complete non-linear mathematical model of the machine, including air thermodynamics, and heat transfer from the walls, as well as heat transfer and fluid resistance in the regenerator, is developed. Non-dimensional groups are derived, and the mathematical model is numerically solved. The heat transfer and work are found for both chambers, and the coefficient of performance of each chamber is calculated. Important design parameters are varied and their effect on refrigerator performance determined. This sensitivity analysis, which shows what the significant parameters are, is a useful tool for the design of practical Stirling refrigeration systems.

Risk and danger among women-who-prostitute in areas where farmworkers predominate.

PubMed

Bletzer, Keith V

2003-06-01

Based on ethnographic research in three agricultural settings in Florida, this article examines one aspect of risk and danger for female sex workers, that of interpersonal violence, while considering women's responses to a shifting sex trade in areas where farmworkers live and work. Sex work in agricultural areas varies from urban sex work. Women eschew pimps, ask for backup from local men entrenched in street settings, and canvass a wide spatial area rather than remained fixed in space. Oscillating between periods of capital-deficiency (nonseason) and capital-intensification (harvest), women respond to increasing risk and danger by building a clientele of regular customers, refusing risky transactions and referrals, and creating a local infrastructure of sanctuary. Some women also construct schemes to relieve men of their money. These men typically are farmworkers, whose vulnerability and image of low risk for HIV expands the potential for risk and danger found in these settings.

Conscious Leadership.

PubMed

Ward, Suzanne F; Haase, Beth

2016-11-01

Health care leaders need to use leadership methodologies that support safe patient care, satisfy employees, and improve the bottom line. Conscious leaders help create desirable personal and professional life experiences for themselves using specific tools that include mindfulness, context, and the observer-self, and they strive to help their employees learn to use these tools as well. In perioperative nursing, conscious leaders create an environment in which nurses are supported in their aim to provide the highest level of patient care and in which transformations are encouraged to take place; this environment ultimately promotes safety, contributes to fulfilling and meaningful work, and enhances a facility's financial viability. This article discusses some of the key concepts behind conscious leadership, how perioperative leaders can reach and maintain expanded consciousness, and how they can best assist their staff members in their own evolution to a more mindful state.

Chemomimetic biocatalysis: exploiting the synthetic potential of cofactor-dependent enzymes to create new catalysts.

PubMed

Prier, Christopher K; Arnold, Frances H

2015-11-11

Despite the astonishing breadth of enzymes in nature, no enzymes are known for many of the valuable catalytic transformations discovered by chemists. Recent work in enzyme design and evolution, however, gives us good reason to think that this will change. We describe a chemomimetic biocatalysis approach that draws from small-molecule catalysis and synthetic chemistry, enzymology, and molecular evolution to discover or create enzymes with non-natural reactivities. We illustrate how cofactor-dependent enzymes can be exploited to promote reactions first established with related chemical catalysts. The cofactors can be biological, or they can be non-biological to further expand catalytic possibilities. The ability of enzymes to amplify and precisely control the reactivity of their cofactors together with the ability to optimize non-natural reactivity by directed evolution promises to yield exceptional catalysts for challenging transformations that have no biological counterparts.

Installation of TVC Actuators in a Two Axis Inertial Load Simulator Test Stand

This paper is about the installation of Space Shuttle Main Engines (SSME) actuators in the new Two Axis Inertial Load Simulator (ILS) at MSFC. The new test stand will support the core stage of the Space Launch System (SLS). Because of the unique geometry of the new test stand standard actuator installation procedures will not work. I have been asked to develop a design on how to install the actuators into the new test stand. After speaking with the engineers and technicians I have created a possible design solution. Using Pro Engineer design software and running my own stress calculations I have proven my design is feasible. I have learned how to calculate the stresses my design will see from this task. From the calculations I have learned I have over built the apparatus. I have also expanded my knowledge of Pro Engineer and was able to create a model of my idea.

The origins of the vaccine cold chain and a glimpse of the future.

International efforts to eradicate smallpox in the 1960s and 1970s provided the foundation for efforts to expand immunization programmes, including work to develop immunization supply chains. The need to create a reliable system to keep vaccines cold during the lengthy journey from the manufacturer to the point of use, even in remote areas, was a crucial concern during the early days of the Expanded Programme on Immunization. The vaccine cold chain was deliberately separated from other medical distribution systems to assure timely access to and control of vaccines and injection materials. The story of the early development of the vaccine cold chain shows how a number of challenges were overcome with technological and human resource solutions. For example, the lack of methods to monitor exposure of vaccines to heat during transport and storage led to many innovations, including temperature-sensitive vaccine vial monitors and better methods to record and communicate temperatures in vaccine stores. The need for appropriate equipment to store and transport vaccines in tropical developing countries led to innovations in refrigeration equipment as well as the introduction and widespread adoption of novel high performance vaccine cold-boxes and carriers. New technologies also helped to make injection safer. Underlying this work on technologies and equipment was a major effort to develop the human resources required to manage and implement the immunization supply chain. This included creating foundational policies and a management infrastructure; providing training for managers, health workers, technicians, and others. The vaccine cold chain has contributed to one of the world's public health success stories and provides three priority lessons for future: the vaccine supply chain needs to be integrated with other public health supplies, re-designed for efficiency and effectiveness and work is needed in the longer term to eliminate the need for refrigeration in the supply chain.

The University of Texas-Houston Health Science Center (UT-Houston) has created programs and activities to address the state's pressing needs in minority education. Through InterCon, a network of universities and K-12 schools, UT-Houston works with its partners to identify competitive candidates in the current pool of minority graduates with bachelor's degrees and to help them--along with their non-minority counterparts--progress in their education. Another objective is to expand the pool of minorities underrepresented in medicine who complete high school and go to college. In 1994 UT-Houston and Prairie View A&M University created a collaborative venture to provide new educational opportunities at UT-Houston for Prairie View's predominantly African American students. A three-track summer internship program--a result of that collaboration--has since been expanded to partnerships with other minority and majority universities throughout Texas. In 1998, for example, 108 undergraduate students from these universities (and 40 other universities nationwide) participated in research, professional, and administrative summer internships at UT-Houston. The InterCon network also has partnerships with K-12 schools. UT-Houston works with inner-city, suburban, and rural school districts to develop education models that can be transferred throughout the state. The partnerships deal with helping to teach basic academic skills and computer literacy, improve science-related instruction, meet demands for health promotion materials and information for school-initiated health and wellness programs, and develop distance-learning paradigms. UT-Houston views InterCon as a program helping Texas institutions to engage and adapt to the socioeconomic factors, demographic changes, and technology explosion that currently challenge public education.

School personnel may lack knowledge of diabetes and be unprepared to address the needs of students with type 1 diabetes. This project evaluated the effectiveness of a type 1 diabetes education program for school personnel on increasing knowledge of diabetes and confidence in caring for students with diabetes. Two types of diabetes education programs were created for school personnel. The basic program provided a 60-minute overview of diabetes. The expanded program, intended for volunteer health aides, provided participants with a more in-depth overview of diabetes during a 180-minute session, including demonstrations of how to assist students with insulin injections. Instruments were created to assess changes in diabetes-related knowledge and confidence in caring for students. Separate knowledge instruments were created for the basic and expanded programs. Knowledge instruments were administered before and after delivery of the education programs to both groups. Confidence instruments were administered before and after for persons completing the expanded program. A total of 81 school personnel participated in the basic (N = 44) or expanded programs (N = 37). Overall knowledge regarding diabetes significantly increased in both the basic and expanded programs from baseline (p < .001). Confidence in caring for students with diabetes also increased from pretest to posttest, both for overall confidence and each individual item (p < .001). Educational programs offered for school personnel can lead to increased knowledge and increased confidence in caring for students with diabetes, which may assist school personnel in addressing the needs of students with diabetes. © 2012, American School Health Association.

Co-creating meaningful structures within long-term psychotherapy group culture.

PubMed

Gayle, Robin G

2009-07-01

Meaningful group structures are co-created within the long-term outpatient psychotherapy group through a hermeneutical interaction between structure and immediate experience of structure by individuals embedded in personal and collective contexts. Co-created meanings expand original group- and self-understandings and further evolve structures that are stable yet do not exist independently of the narratives and affects of the members who interact with them. Group structures do not reduce, expand, or dissolve but change in connection to the experiences and meaning attributions within the group. This intersubjective process mediates the emphasis within group theory on leader responsibility for culture building that risks overpromoting certain psychotherapeutic cultural intentions over others. Three examples of intersubjective hermeneutical interaction within long-term psychotherapy groups lend insight into global, cultural, and societal groups.

The NASA Center for Climate Simulation (NCCS) at the Goddard Space Flight Center and the Earth System Grid Federation (ESGF) are working together to build a uniform environment for the comparative study and use of a group of reanalysis datasets of particular importance to the research community. This effort is called the Collaborative REAnalysis Technical Environment (CREATE) and it contains two components: the CREATE-Intercomparison Project (CREATE-IP) and CREATE-V. This year's efforts included generating and publishing an atmospheric reanalysis ensemble mean and spread and improving the analytics available through CREATE-V. Related activities included adding access to subsets of the reanalysis data through ArcGIS and expanding the visualization tool to GMAO forecast data. This poster will present the access mechanisms to this data and use cases including example Jupyter Notebook code. The reanalysis ensemble was generated using two methods, first using standard Python tools for regridding, extracting levels and creating the ensemble mean and spread on a virtual server in the NCCS environment. The second was using a new analytics software suite, the Earth Data Analytics Services (EDAS), coupled with a high-performance Data Analytics and Storage System (DASS) developed at the NCCS. Results were compared to validate the EDAS methodologies, and the results, including time to process, will be presented. The ensemble includes selected 6 hourly and monthly variables, regridded to 1.25 degrees, with 24 common levels used for the 3D variables. Use cases for the new data and services will be presented, including the use of EDAS for the backend analytics on CREATE-V, the use of the GMAO forecast aerosol and cloud data in CREATE-V, and the ability to connect CREATE-V data to NCCS ArcGIS services.

This article analyzes the features of fostering optoelectronic students' innovative practical ability based on the knowledge structure of optoelectronic disciplines, which not only reveals the common law of cultivating students' innovative practical ability, but also considers the characteristics of the major: (1) The basic theory is difficult, and the close combination of science and technology is obvious; (2)With the integration of optics, mechanics, electronics and computer, the system technology is comprehensive; (3) It has both leading-edge theory and practical applications, so the benefit of cultivating optoelectronic students is high ; (4) The equipment is precise and the practice is costly. Considering the concept and structural characteristics of innovative and practical ability, and adhering to the idea of running practice through the whole process, we put forward the construction of three-dimensional innovation and practice platform which consists of "Synthetically Teaching Laboratory + Innovation Practice Base + Scientific Research Laboratory + Major Practice Base + Joint Teaching and Training Base", and meanwhile build a whole-process progressive training mode to foster optoelectronic students' innovative practical ability, following the process of "basic experimental skills training - professional experimental skills training - system design - innovative practice - scientific research project training - expanded training - graduation project": (1) To create an in - class practical ability cultivation environment that has distinctive characteristics of the major, with the teaching laboratory as the basic platform; (2) To create an extra-curricular innovation practice activities cultivation environment that is closely linked to the practical application, with the innovation practice base as a platform for improvement; (3) To create an innovation practice training cultivation environment that leads the development of cutting-edge, with the scientific research laboratory as a platform to explore; (4) To create an out-campus expanded training environment of optoelectronic major practice and optoelectronic system teaching and training, with the major practice base as an expansion of the platform; (5) To break students' "pre-job training barriers" between school and work, with graduation design as the comprehensive training and testing link.

2012-01-01

A method, apparatus and computer program for determining and utilizing a time-expanded decision network is presented. A set of potential system configurations is defined. Next, switching costs are quantified to create a "static network" that captures the difficulty of switching among these configurations. A time-expanded decision network is provided by expanding the static network in time, including chance and decision nodes. Minimum cost paths through the network are evaluated under plausible operating scenarios. The set of initial design configurations are iteratively modified to exploit high-leverage switches and the process is repeated to convergence. Time-expanded decision networks are applicable, but not limited to, the design of systems, products, services and contracts.

Novel translators and logic devices based on nanotechnology concepts are under intense development. The potential for ultra-low power circuitry makes nanotechnology attractive for applications such as digital electronics and sensors. Furthermore, the ability to form devices on flexible substrates expands the range of applications where electronic circuitry can be introduced. For NASA, nonotechndogy offers opportunities for increased onboard data processing and thus autonomous decision-making ability, ad novel sensors that detect and respond to external stimuli with few oversight requirements. The goat of this work is to demonstrate transistor behavior in polyaniline/ polyethylene oxide nanofibers, thus creating a foundation for future logic devices.

The 5-year survival rate for ovarian cancer is only 45% largely due to lack of effective screening methods. Current methods include palpation, transvaginal ultrasound, and the CA-125 blood test. Finding disease reliably and at an early stage increase survival to 92%. We have designed and built a 0.7 mm endoscope for the early detection of ovarian cancer. Inserted transvaginally through the working channel of a hysteroscope, the falloposcope creates a minimally invasive procedure for the screening of high risk women. To improve the ease-of-use and safety of falloposcope deployment, we are working to create an everting balloon. Currently, the falloposcope would require a skilled user to operate due to the challenging anatomy of the fallopian tubes - a small opening from the uterus (< 1 mm), tortuous path, and delicate lumenal features. A balloon delivery system would gently open the fallopian tube and guide the falloposcope down the center of lumen. We show balloon design and discuss integration with the falloposcope prototype. We test possible mechanical damage to the tissue due to scraping, puncture, or overstretching. Successful introduction of the everting balloon to simplify falloposcope delivery could expand screening beyond specialized centers to smaller clinical locations.

Expanding NASA Science Cooperation with New Partners

Allen, Marc; Bress, Kent

Expanding NASA Science Cooperation with New Partners When NASA was created in 1958, it was given a goal of "cooperation by the United States with other nations and groups of nations in work done pursuant to this Act and in the peaceful application of the results." As science has become increasingly globalized during the past 50 years, NASA and its many partners in space and Earth science research have benefited enormously from pooling ideas, skills, and resources for joint undertakings. The discoveries made have powerfully advanced public awareness of science and its importance all over the world. Today, the U.S. Administra-tion is encouraging NASA to expand its cooperation with new and emerging partners. NASA space and Earth science cooperation is founded on scientist-to-scientist research collaboration. Space missions are very costly and technically challenging, but there are many other important areas for international cooperation. Areas ripe for expansion with new partners include space data sharing, scientist-to-scientist collaborative research, international research program plan-ning and coordination, Earth applications for societal benefit, ground-based measurements for Earth system science, and education and public outreach. This presentation lays out NASA's general principles for international science cooperation, briefly describes each of these opportu-nity areas, and suggests avenues for initiating new cooperative relationships.

The Australian Government's Partners in Recovery (PIR) program established a new form of mental health intervention which required multiple sectors, services and consumers to work in a more collaborative way. Brisbane North Primary Health Network applied a value co-creation approach with partners and end users, engaging more than 100 organisations in the development of a funding submission to PIR. Engagement platforms were established and continue to provide opportunities for new co-creation experiences. Initially, seven provider agencies - later expanded to eight to include an Aboriginal and Torres Strait Islander provider organisation - worked collaboratively as a Consortium Management Committee. The co-creation development process has been part of achieving the co-created outcomes, which include new initiatives, changes to existing interventions and referral practices, and an increased understanding and awareness of end users' needs.

The Field Test study is currently in full swing, preceded by the successful completion of the Pilot Field Test study that paved the way for collecting data on the astronauts in the medical tent in Kazakhstan. Abigail Sherriff worked alongside Logan Dobbe on one Field Test aspect to determine foot clearance over obstacles (5cm, 10cm, and 15cm) using APDM Inc. Internal Measurement Units (IMU) worn by the astronauts. They created a program to accurately calculate foot clearance using the accelerometer, magnetometer, and gyroscope data with the IMUs attached to the top of the shoes. To validate the functionality of their program, they completed a successful study on test subjects performing various tasks in an optical motion studio, considered a gold standard in biomechanics research. Future work will include further validation and expanding the program to include other analyses.

Delgado, Pedro

2016-01-01

The Atlantic Healthcare Collaboration for Innovation and Improvement in Chronic Disease (AHC) set out to achieve three aims: to create a patient- and family-centred approach to manage chronic diseases; to build a network of organizational, regional and provincial teams to share evidence-informed, systems-level solutions and work together to develop, implement and sustain improvement initiatives; and to promote the sustainability of the participating health systems. Important elements of all three aims were achieved and the synthesis provides a meaningful contribution to systems working to improve chronic care. This paper explores those achievements as well as some of the areas for improvement, including replicability, expanded outcome measurement, greater detail around patient and family engagement, increased focus on specific outcomes and processes, and further articulation of lessons learned and recommendations.

Ablation, Thermal Response, and Chemistry Program for Analysis of Thermal Protection Systems

2010-01-01

In previous work, the authors documented the Multicomponent Ablation Thermochemistry (MAT) and Fully Implicit Ablation and Thermal response (FIAT) programs. In this work, key features from MAT and FIAT were combined to create the new Fully Implicit Ablation, Thermal response, and Chemistry (FIATC) program. FIATC is fully compatible with FIAT (version 2.5) but has expanded capabilities to compute the multispecies surface chemistry and ablation rate as part of the surface energy balance. This new methodology eliminates B' tables, provides blown species fractions as a function of time, and enables calculations that would otherwise be impractical (e.g. 4+ dimensional tables) such as pyrolysis and ablation with kinetic rates or unequal diffusion coefficients. Equations and solution procedures are presented, then representative calculations of equilibrium and finite-rate ablation in flight and ground-test environments are discussed.

2014-06-15

Purpose: The Vero4DRT has a maximum field size of 150×150 mm{sup 2}. The purposes of this study were to develop an expanded field irradiation technique using a unique gimbaled x-ray head of Vero4DRT and to evaluate its dosimetric characteristic. Methods: The expanded field irradiation consisted of four separate fields with 2.39 degree gimbal rotation around orthogonal two axes. The central beam axis for each field shifted 40 mm from the isocenter for longitudinal and lateral directions, and thus, the field size was expanded up to 230×230 mm{sup 2}. Adjacent region were created at the isocenter (center-adjacent expanded-field) and 20 mmmore » from isocenter (offadjacent expanded-field). To create flat dose distribution in the combined piecewise-fields, the overlapping and gaps regions on the isocenter plane were adjusted with the gimbal rotating and the MLC. To evaluate dosimetric characteristic of the expanded-field, films inserted in water-equivalent phantoms at 50, 100 and 150 mm depth were irradiated and the field size, penumbra, flatness and symmetry were analyzed.In addition, the expandedfield irradiation technique was applied to IMRT. A head and neck IMRT field, which was planned for the conventional linac (Varian Clinac iX), was reproduced with the expanded-field of the Vero4DRT. The simulated dose distribution for the expanded IMRT field was compared to the measured dose distribution. Results: The field size, penumbra, flatness and symmetry of center- and off- adjacent expanded-fields were 230.2–232.1 mm, 7.8–10.7 mm, 2.3–6.5% and –0.5–0.4% at 100 mm depth. The 82.1% area of the expanded IMRT dose distribution was within 5% difference between measurement and simulation, which was analyzed upper 50% dose area, and the 3%/3 mm gamma pass rate was 98.4%. Conclusions: The expandedfield technique was developed using the gimbaled x-ray head. To extend applied targets, such as whole breast irradiations or head and neck IMRT, the expanded-field technique would be effective.« less

Onoufrios, the famous XVI's century iconographer, creator of the ``Berati School'': studying the technique and materials used in wall paintings of inscribed churches

NASA Astrophysics Data System (ADS)

Pavlidou, E.; Arapi, M.; Zorba, T.; Anastasiou, M.; Civici, N.; Stamati, F.; Paraskevopoulos, K. M.

The study of the materials and techniques employed for wall painting, complementing the information from historical and aesthetic data, contributes to the integrated knowledge of the iconographer and his period. In the 16th century, regarding the iconography in the former Byzantine area, besides the School of Crete and Francos Catelanos and his school, a third artistic personality who also created his own school, Onoufrios, appeared in central Albania and expanded his activity as a painter to northern Greece as well as nearby areas, such as Ohrid. Inscriptions documenting the works of Onoufrios are found in some of the churches that he decorated with wall paintings: “St. Apostles” (1547) Kastoria Greece, “St. Nicolas” Shelcan Albania, “St. Paraskevi” (1554), Valsh Albania, while are attributed to him the church of “St. Theodores” in Berati, Albania (before 1547) and others. He is one of the best icon painters of the whole Balkan region, and the best painter that has ever worked in Albanian territory. Onoufrios managed to combine the local painting tradition with the best tradition of the eastern (Paleologian) and western (Italian) schools, resulting in a realistic and natural depiction. He is the creator of the “Berati School” that expanded to other parts of the peninsula. His individual character can be distinguished in the work of his students: his son Nikolaos (who inherited his style in painting), Onoufrios from Cyprus, etc. Based on careful observations, we extracted number of paint samples from wall paintings of three of the above mentioned churches. Ground and paint layers were examined using micro-FTIR, Optical Microscopy, TXRF and SEM-EDS, to characterize materials and methods used by the artist to create these works. Our findings in each church are discussed and compared with the others in order to understand how and with what material and resources the painter worked and how he developed his technique. The presence of calcium carbonate as the main component in all FTIR measurements points to a fresco technique. Pigments like red and yellow ochre, carbon black, green earth, calcium carbonate are used in all cases. The use of gypsum in the plaster construction is characteristic. The deterioration of the wall paintings due to environmental effects different in every church is also examined.

Heryawan, Yudi; Park, Hoon C.; Goo, Nam S.; Yoon, Kwang J.; Byun, Yung H.

2005-05-01

In this paper, we present design, manufacturing, and wind tunnel test for a small-scale expandable morphing wing. The wing is separated into inner and outer wings as a typical bird wing. The part from leading edge of the wing chord is made of carbon composite strip and balsa. The remaining part is covered with curved thin carbon fiber composite mimicking wing feathers. The expandable wing is driven by a small DC motor, reduction gear, and fiber reinforced composite linkages. Rotation of the motor is switched to push-pull linear motion by a screw and the linear motion of the screw is transferred to linkages to create wing expansion and folding motions. The wing can change its aspect ratio from 4.7 to 8.5 in about 2 seconds and the speed can be controlled. Two LIPCAs (Lightweight Piezo-Composite Actuators) are attached under the inner wing section and activated on the expanded wing state to modify camber of the wing. In the wind tunnel test, change of lift, drag, and pitching moment during wing expansion have been investigated for various angles of attack. The LIPCA activation has created significant additional lift.

Creating Student Engagement Through Immersion: Exploring the MT6 Shipwreck in Puget Sound via Submersible, Using a Team Challenge Format

Educational literature has many stories describing the "aha" moment that teachers are privileged to observe: a student who suddenly grasps a concept (ding!), dives into an activity (whee!) or works tirelessly to complete a complicated project (wow!). Designing moments like these for students can be one of the great joys of teaching. Experiencing such a moment can have a lasting impact on student engagement and motivation, and is the underlying rationale for the importance of creating a wide array of outreach efforts, from field work to telepresence activities.During the spring of 2015, OceanGate Foundation and Seattle Central College partnered on a pilot program to design a program that had this kind of impact and created the Open The Oceans Challenge. Student teams responded to our Request for Proposal (RFP), which was centered around the exploration of a shipwreck in 150 meters of water just off the Seattle waterfront, the MT-6. Students spent a significant amount of time crafting their proposals and reported that they enjoyed the process of writing the proposal as a team. The two winning teams accompanied us on a series of submersible dives performed by OceanGate, Inc. and worked up the results afterward. In addition to researching the MT-6 wreck and documenting what they found, students were able to do basic observational research on the wreck, providing sonar and photographic data that will help form the basis of future expeditions to this site.We report on lessons learned from this pilot — the impact for the small set of students involved in this project was profound, but how can we expand the reach of such activities? Results from this experience suggest that providing a highly engaging topic and expedition may not be enough to inspire an "aha" moment that creates lasting engagement; the scaffolding and mentorship that surrounds a rich experience is also critical.

Remotely Operated Vehicles (ROVs) Provide a "Big Data Progression"

NASA Astrophysics Data System (ADS)

Oostra, D.; Sanghera, S. S.; Mangosing, D. C., Jr.; Lewis, P. M., Jr.; Chambers, L. H.

2015-12-01

This year, science and technology teams at the NASA Langley Science Directorate were challenged with creating an API-based web application using RockBlock Mobile sensors mounted on a zero pressure high-altitude balloon. The system tracks and collects meteorological data parameters and visualizes this data in near real time, using a MEAN development stack to create an HTML5 based tool that can send commands to the vehicle, parse incoming data, and perform other functions to store and serve data to other devices. NASA developers and science educators working on this project saw an opportunity to use this emerging technology to address a gap identified in science education between middle and high school curricula. As students learn about data analysis in elementary and middle school, they are taught to collect data from in situ sources. In high school, students are then asked to work with remotely sensed data, without always having the experience or understanding of how that data is collected. We believe that using ROVs to create a "big data progression" for students will not only enhance their ability to understand how remote satellite data is collected, but will also provide the outlet for younger students to expand their interest in science and data prior to entering high school. In this presentation, we will share and discuss our experiences with ROVs, APIs and data viz applications, with a focus on the next steps for developing this emerging capability.

Heat-resistant DNA tile arrays constructed by template-directed photoligation through 5-carboxyvinyl-2′-deoxyuridine

PubMed Central

Tagawa, Miho; Shohda, Koh-ichiroh; Fujimoto, Kenzo; Sugawara, Tadashi; Suyama, Akira

2007-01-01

Template-directed DNA photoligation has been applied to a method to construct heat-resistant two-dimensional (2D) DNA arrays that can work as scaffolds in bottom-up assembly of functional biomolecules and nano-electronic components. DNA double-crossover AB-staggered (DXAB) tiles were covalently connected by enzyme-free template-directed photoligation, which enables a specific ligation reaction in an extremely tight space and under buffer conditions where no enzymes work efficiently. DNA nanostructures created by self-assembly of the DXAB tiles before and after photoligation have been visualized by high-resolution, tapping mode atomic force microscopy in buffer. The improvement of the heat tolerance of 2D DNA arrays was confirmed by heating and visualizing the DNA nanostructures. The heat-resistant DNA arrays may expand the potential of DNA as functional materials in biotechnology and nanotechnology. PMID:17982178

There are significant differences in weight and volumetric characteristics between silicone and saline breast implants of which most plastic surgeons are unaware. Phase I of this study was a weight measurement focused on recording differences in the weight of saline volumes instilled versus recorded weights of saline implants and expanders. Phase II compared displaced volume differences of tissue expanders with instilled volumes. As a result of this study, surgeons should now be able to precisely calculate the volume created for breast pocket development, allowing for accurate matching of expander and final breast implant.

Zhuang, Linda; Zhu, Annie; Zhang, Yifan; Sweis, Jason; Lai, Ya-Chieh

2017-03-01

Pattern-based approaches are becoming more common and popular as the industry moves to advanced technology nodes. At the beginning of a new technology node, a library of process weak point patterns for physical and electrical verification are starting to build up and used to prevent known hotspots from re-occurring on new designs. Then the pattern set is expanded to create test keys for process development in order to verify the manufacturing capability and precheck new tape-out designs for any potential yield detractors. With the database growing, the adoption of pattern-based approaches has expanded from design flows to technology development and then needed for mass-production purposes. This paper will present the complete downstream working flows of a design pattern database(PDB). This pattern-based data analysis flow covers different applications across different functional teams from generating enhancement kits to improving design manufacturability, populating new testing design data based on previous-learning, generating analysis data to improve mass-production efficiency and manufacturing equipment in-line control to check machine status consistency across different fab sites.

Optimizing stellarator coil winding surfaces with Regcoil

NASA Astrophysics Data System (ADS)

Bader, Aaron; Landreman, Matt; Anderson, David; Hegna, Chris

2017-10-01

We show initial attempts at optimizing a coil winding surface using the Regcoil code [1] for selected quasi helically symmetric equilibria. We implement a generic optimization scheme which allows for variation of the winding surface to allow for improved diagnostic access and allow for flexible divertor solutions. Regcoil and similar coil-solving algorithms require a user-input winding surface, on which the coils lie. Simple winding surfaces created by uniformly expanding the plasma boundary may not be ideal. Engineering constraints on reactor design require a coil-plasma separation sufficient for the introduction of neutron shielding and a tritium generating blanket. This distance can be the limiting factor in determining reactor size. Furthermore, expanding coils in other regions, where possible, can be useful for diagnostic and maintenance access along with providing sufficient room for a divertor. We minimize a target function that includes as constraints, the minimum coil-plasma distance, the winding surface volume, and the normal magnetic field on the plasma boundary. Results are presented for two quasi-symmetric equilibria at different aspect ratios. Work supported by the US DOE under Grant DE-FG02-93ER54222.

Older Workers and Federal Work Programs: The Korean Senior Employment Program (KSEP).

PubMed

Choi, Eunhee

2016-01-01

Federal older worker programs are attracting attention due to the growing number of older workers across the world. They are uniquely situated to provide out-of-market work opportunities to older job seekers, who often find their age a barrier to securing desirable jobs. In 2004, the Korean government established its own program, the Korean Senior Employment Program (KSEP); however, literature for international readers on this innovative program is lacking. Thus, this article aims to provide an in-depth description of KSEP and a brief comparison between the Senior Community Service Employment Program in the U.S. and KSEP. The unique characteristics of KSEP include having the dual program foci on supplemental income and social participation; expanding work opportunities in the private sector beyond community-based jobs; accepting participants who are financially disadvantaged as well as those with a high desire for social participation regardless of their income; and broadening work opportunities for those with professional skills beyond repetitive, simple, and temporary jobs. This article may offer helpful insights to older worker advocates from various countries in creating or modifying their programs.

Apparatus for detecting alpha radiation in difficult access areas

DOEpatents

Steadman, P.; MacArthur, D.W.

1997-09-02

An electrostatic alpha radiation detector for measuring alpha radiation emitted from inside an enclosure comprising an electrically conductive expandable electrode for insertion into the enclosure is disclosed. After insertion, the electrically conductive expandable electrode is insulated from the enclosure and defines a decay cavity between the electrically conductive expandable electrode and the enclosure so that air ions generated in the decay cavity are electrostatically captured by the electrically conductive expandable electrode and the enclosure when an electric potential is applied between the electrically conductive expandable electrode and the enclosure. Indicator means are attached to the electrically conductive expandable electrode for indicating an electrical current produced by generation of the air ions generated in the decay cavity by collisions between air molecules and the alpha particles emitted from the enclosure. A voltage source is connected between the indicator means and the electrically conductive enclosure for creating an electric field between the electrically conductive expandable electrode and the enclosure. 4 figs.

Global health partnership for student peer-to-peer psychiatry e-learning: Lessons learned.

PubMed

Keynejad, Roxanne C

2016-12-03

Global 'twinning' relationships between healthcare organizations and institutions in low and high-resource settings have created growing opportunities for e-health partnerships which capitalize upon expanding information technology resources worldwide. E-learning approaches to medical education are increasingly popular but remain under-investigated, whilst a new emphasis on global health teaching has coincided with university budget cuts in many high income countries. King's Somaliland Partnership (KSP) is a paired institutional partnership health link, supported by Tropical Health and Education Trust (THET), which works to strengthen the healthcare system and improve access to care through mutual exchange of skills, knowledge and experience between Somaliland and King's Health Partners, UK. Aqoon, meaning knowledge in Somali, is a peer-to-peer global mental health e-learning partnership between medical students at King's College London (KCL) and Hargeisa and Amoud Universities, Somaliland. It aims to extend the benefits of KSP's cross-cultural and global mental health education work to medical students and has reported positive results, including improved attitudes towards psychiatry in Somaliland students. The process of devising, piloting, evaluating, refining, implementing, re-evaluating and again refining the Aqoon model has identified important barriers to successful partnership. This article describes lessons learned during this process, sharing principles and recommendations for readers wishing to expand their own global health link beyond qualified clinicians, to the healthcare professionals of the future.

Method for forming a layer of synthetic corrosion products on tubing surfaces

DOEpatents

Lane, Michael H.; Salamon, Eugene J. M.

1996-01-01

A method is provided for forming a synthetic corrosion product layer on tube surfaces. The method utilizes two dissimilar materials with different coefficients of thermal expansion. An object tube and sacrificial tube are positioned one inside the other such that an annular region is created between the two tubes' surfaces. A slurry of synthetic corrosion products is injected into this annular region and the assembly is heat treated. This heat causes the tubes to expand, the inner tube with the higher coefficient of expansion expanding more than the outer tube, thereby creating internal pressures which consolidate the corrosion products and adhere the corrosion products to the tubing surfaces. The sacrificial tube may then be removed by conventional chemical etching or mechanical methods.

Over the last six decades, federal investments in scientific research have led to unquestionable economic and societal advances, while expanding human knowledge. Yet, in the current federal fiscal climate, funding for fundamental research is being challenged in some quarters. This situation has created the need for stakeholders in science to step forward and defend the role that basic research plays in creating the knowledge and workforce necessary to address current and future challenges. Communicating to fellow scientists in this environment is necessary but not sufficient to sustaining, or even expanding, support for fundamental research. A multi-faceted approach will be described for enhancing communication to broader audiences, including policy makers and the general public, increasingly responsible for ensuring the future of scientific progress.

Heidemann, Ivonete T S B; Almeida, Maria C P

2011-01-01

ABSTRACT Objective: The study analyzes the possibility of incorporating health promotion measures into the work processes of Family Health Program teams at a primary health care clinic in Brazil. We used the participatory research concept developed in 1968 by Freire. The study sample comprised the end-users of the health care system, together with 3 multidisciplinary teams. A total of 77 health care users and 55 health professionals participated in the study. Culture circles composed of health care professionals, and users from different areas investigated generative topics, encoded/decoded topics, and engaged in critical probing for clarification. Topics affecting quality of life and health were heuristically evaluated. Although most topics were related to changing the focus of health care facilities, some were related to subsidizing community-based interventions, improving environmental strategies, individual skills, and public policies. Incorporating the novel health promotion measures and creating an expanded full-treatment clinic are important steps toward that goal. Topics that can stimulate dialogue among the members of the culture circles include creating an environment of closer cultural contact, with repercussions for work processes, family health models, and general health models, as well as the inclusion of social aspects in the decision-making processes related to health issues that affect the living conditions of the population. © 2010 Wiley Periodicals, Inc.

Objective forensic analysis of striated, quasi-striated and impressed toolmarks

NASA Astrophysics Data System (ADS)

Spotts, Ryan E.

Following the 1993 Daubert v. Merrell Dow Pharmaceuticals, Inc. court case and continuing to the 2010 National Academy of Sciences report, comparative forensic toolmark examination has received many challenges to its admissibility in court cases and its scientific foundations. Many of these challenges deal with the subjective nature in determining whether toolmarks are identifiable. This questioning of current identification methods has created a demand for objective methods of identification - "objective" implying known error rates and statistically reliability. The demand for objective methods has resulted in research that created a statistical algorithm capable of comparing toolmarks to determine their statistical similarity, and thus the ability to separate matching and nonmatching toolmarks. This was expanded to the creation of virtual toolmarking (characterization of a tool to predict the toolmark it will create). The statistical algorithm, originally designed for two-dimensional striated toolmarks, had been successfully applied to striated screwdriver and quasi-striated plier toolmarks. Following this success, a blind study was conducted to validate the virtual toolmarking capability using striated screwdriver marks created at various angles of incidence. Work was also performed to optimize the statistical algorithm by implementing means to ensure the algorithm operations were constrained to logical comparison regions (e.g. the opposite ends of two toolmarks do not need to be compared because they do not coincide with each other). This work was performed on quasi-striated shear cut marks made with pliers - a previously tested, more difficult application of the statistical algorithm that could demonstrate the difference in results due to optimization. The final research conducted was performed with pseudostriated impression toolmarks made with chisels. Impression marks, which are more complex than striated marks, were analyzed using the algorithm to separate matching and nonmatching toolmarks. Results of the conducted research are presented as well as evidence of the primary assumption of forensic toolmark examination; all tools can create identifiably unique toolmarks.

Enhancing microbial production of biofuels by expanding microbial metabolic pathways.

PubMed

Yu, Ping; Chen, Xingge; Li, Peng

2017-09-01

Fatty acid, isoprenoid, and alcohol pathways have been successfully engineered to produce biofuels. By introducing three genes, atfA, adhE, and pdc, into Escherichia coli to expand fatty acid pathway, up to 1.28 g/L of fatty acid ethyl esters can be achieved. The isoprenoid pathway can be expanded to produce bisabolene with a high titer of 900 mg/L in Saccharomyces cerevisiae. Short- and long-chain alcohols can also be effectively biosynthesized by extending the carbon chain of ketoacids with an engineered "+1" alcohol pathway. Thus, it can be concluded that expanding microbial metabolic pathways has enormous potential for enhancing microbial production of biofuels for future industrial applications. However, some major challenges for microbial production of biofuels should be overcome to compete with traditional fossil fuels: lowering production costs, reducing the time required to construct genetic elements and to increase their predictability and reliability, and creating reusable parts with useful and predictable behavior. To address these challenges, several aspects should be further considered in future: mining and transformation of genetic elements related to metabolic pathways, assembling biofuel elements and coordinating their functions, enhancing the tolerance of host cells to biofuels, and creating modular subpathways that can be easily interconnected. © 2016 International Union of Biochemistry and Molecular Biology, Inc.

Kujala, Sari; Rajalahti, Elina; Heponiemi, Tarja; Hilama, Pirjo

2018-01-01

An increasing number of new eHealth services that support patients' self-management has changed health professionals' work and has created a need for a new eHealth competence. In this study, we evaluated the health professionals' eHealth competences and training needs in a public health organization in Finland. The target organization's goal was to increase the number of eHealth services provided to patients, and health professionals and their competences were seen as critical for the adoption of services. Data was collected through an online survey of 701 health professionals working in the target organization. Professionals perceived their basic computer skills as good and they were mostly willing to use eHealth services in patient work. However, health professionals need guidance, especially in their patient work in the new eHealth-enabled environment. They were less confident about their competence to motivate and advise patients to use eHealth services and how to communicate with patients using eHealth solutions. The results also imply that eHealth competence is not merely about an individual's skills but that organizations need to develop new working processes, work practices and distribution of work. We suggest that the training and support needs identified be considered in curricula and lifelong learning.

The EELR are regions of highly-excited ionized gas that extend throughout the outskirts of their host galaxies. Concerning FR II radio galaxies, alignment between optical and radio structures were found for several sources. We investigate the ionizing mechanisms of these regions through long-slit spectroscopic analysis. Photoionization models, where both the AGN and a mixed intergalactic medium may explain the ionization state of the regions are studied. But also the shock-ionization model is tested since it can provide a local budget of ionizing photons created by expanding radiative shock waves driven by the radio jet.

Klimenko, A. V.; Agababov, V. S.; Koryagin, A. V.; Baidakova, Yu. O.

2016-05-01

The problems of using the expander-generator unit (EGU) to generate refrigeration, along with electricity were considered. It is shown that, on the level of the temperatures of refrigeration flows using the EGU, one can provide the refrigeration supply of the different consumers: ventilation and air conditioning plants and industrial refrigerators and freezers. The analysis of influence of process parameters on the cooling power of the EGU, which depends on the parameters of the gas expansion process in the expander and temperatures of cooled environment, was carried out. The schematic diagram of refrigeration generation plant based on EGU is presented. The features and advantages of EGU to generate refrigeration compared with thermotransformer of steam compressive and absorption types were shown, namely: there is no need to use the energy generated by burning fuel to operate the EGU; beneficial use of the heat delivered to gas from the flow being cooled in equipment operating on gas; energy production along with refrigeration generation, which makes it possible to create, using EGU, the trigeneration plants without using the energy power equipment. It is shown that the level of the temperatures of refrigeration flows, which can be obtained by using the EGU on existing technological decompression stations of the transported gas, allows providing the refrigeration supply of various consumers. The information that the refrigeration capacity of an expander-generator unit not only depends on the parameters of the process of expansion of gas flowing in the expander (flow rate, temperatures and pressures at the inlet and outlet) but it is also determined by the temperature needed for a consumer and the initial temperature of the flow of the refrigeration-carrier being cooled. The conclusion was made that the expander-generator units can be used to create trigeneration plants both at major power plants and at small energy.

CHAIN RECONNECTIONS OBSERVED IN SYMPATHETIC ERUPTIONS

DOE Office of Scientific and Technical Information (OSTI.GOV)

Joshi, Navin Chandra; Magara, Tetsuya; Schmieder, Brigitte

2016-04-01

The nature of various plausible causal links between sympathetic events is still a controversial issue. In this work, we present multiwavelength observations of sympathetic eruptions, associated flares, and coronal mass ejections (CMEs) occurring on 2013 November 17 in two close active regions. Two filaments, i.e., F1 and F2, are observed in between the active regions. Successive magnetic reconnections, caused for different reasons (flux cancellation, shear, and expansion) have been identified during the whole event. The first reconnection occurred during the first eruption via flux cancellation between the sheared arcades overlying filament F2, creating a flux rope and leading to themore » first double-ribbon solar flare. During this phase, we observed the eruption of overlying arcades and coronal loops, which leads to the first CME. The second reconnection is believed to occur between the expanding flux rope of F2 and the overlying arcades of filament F1. We suggest that this reconnection destabilized the equilibrium of filament F1, which further facilitated its eruption. The third stage of reconnection occurred in the wake of the erupting filament F1 between the legs of the overlying arcades. This may create a flux rope and the second double-ribbon flare and a second CME. The fourth reconnection was between the expanding arcades of the erupting filament F1 and the nearby ambient field, which produced the bi-directional plasma flows both upward and downward. Observations and a nonlinear force-free field extrapolation confirm the possibility of reconnection and the causal link between the magnetic systems.« less

Analysis of Zinc Oxide Thin Films Synthesized by Sol-Gel via Spin Coating

NASA Astrophysics Data System (ADS)

Wolgamott, Jon Carl

Transparent conductive oxides are gaining an increasingly important role in optoelectronic devices such as solar cells. Doped zinc oxide is a candidate as a low cost and nontoxic alternative to tin doped indium oxide. Lab results have shown that both n-type and p-type zinc oxide can be created on a small scale. This can allow zinc oxide to be used as either an electrode as well as a buffer layer to increase efficiency and protect the active layer in solar cells. Sol-gel synthesis is emerging as a low temperature, low cost, and resource efficient alternative to producing transparent conducting oxides such as zinc oxide. For sol-gel derived zinc oxide thin films to reach their potential, research in this topic must continue to optimize the known processing parameters and expand to new parameters to tighten control and create novel processing techniques that improve performance. The processing parameters of drying and annealing temperatures as well as cooling rate were analyzed to see their effect on the structure of the prepared zinc oxide thin films. There were also preliminary tests done to modify the sol-gel process to include silver as a dopant to produce a p-type thin film. The results from this work show that the pre- and post- heating temperatures as well as the cooling rate all play their own unique role in the crystallization of the film. Results from silver doping show that more work needs to be done to create a sol-gel derived p-type zinc oxide thin film.

Creating Stiff, Tough, and Functional Hydrogel Composites with Low-Melting-Point Alloys.

PubMed

Takahashi, Riku; Sun, Tao Lin; Saruwatari, Yoshiyuki; Kurokawa, Takayuki; King, Daniel R; Gong, Jian Ping

2018-04-01

Reinforcing hydrogels with a rigid scaffold is a promising method to greatly expand the mechanical and physical properties of hydrogels. One of the challenges of creating hydrogel composites is the significant stress that occurs due to swelling mismatch between the water-swollen hydrogel matrix and the rigid skeleton in aqueous media. This stress can cause physical deformation (wrinkling, buckling, or fracture), preventing the fabrication of robust composites. Here, a simple yet versatile method is introduced to create "macroscale" hydrogel composites, by utilizing a rigid reinforcing phase that can relieve stress-induced deformation. A low-melting-point alloy that can transform from a load-bearing solid state to a free-deformable liquid state at relatively low temperature is used as a reinforcing skeleton, which enables the release of any swelling mismatch, regardless of the matrix swelling degree in liquid media. This design can generally provide hydrogels with hybridized functions, including excellent mechanical properties, shape memory, and thermal healing, which are often difficult or impossible to achieve with single-component hydrogel systems. Furthermore, this technique enables controlled electrochemical reactions and channel-structure templating in hydrogel matrices. This work may play an important role in the future design of soft robots, wearable electronics, and biocompatible functional materials. © 2018 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim.

The turbocompressor comprises a power turbine and a compressor turbine having respective rotors and on a common shaft, rotatably supported by bearings. A first working fluid is supplied by a power loop and is expanded in the turbine. A second working fluid is compressed in the turbine and is circulated in a heat pump loop. A lubricant is mixed with the second working fluid but is excluded from the first working fluid. The bearings are cooled and lubricated by a system which circulates the second working fluid and the intermixed lubricant through the bearings. Such system includes a pump, a thermostatic expansion valve for expanding the working fluid into the space between the bearings, and a return conduit system for withdrawing the expanded working fluid after it passes through the bearings and for returning the working fluid to the evaporator. A shaft seal excludes the lubricant from the power turbine. The power loop includes a float operable by liquid working fluid in the condenser for controlling a recirculation valve so as to maintain a minimum liquid level in the condenser, while causing a feed pump to pump most of the working fluid into the vapor generator. The heat pump compressor loop includes a float in the condenser for operating and expansion valve to maintain a minimum liquid working fluid level in the condenser while causing most of the working fluid to be expanded into the evaporator.

In this paper we discuss the transformation of a sheet of material into a wide range of desired shapes and patterns by introducing a set of simple cuts in a multilevel hierarchy with different motifs. Each choice of hierarchical cut motif and cut level allows the material to expand into a unique structure with a unique set of properties. We can reverse-engineer the desired expanded geometries to find the requisite cut pattern to produce it without changing the physical properties of the initial material. The concept was experimentally realized and applied to create an electrode that expands to >800% the original area with only very minor stretching of the underlying material. The generality of our approach greatly expands the design space for materials so that they can be tuned for diverse applications.

Measurement of Debye length in laser-produced plasma.

NASA Technical Reports Server (NTRS)

Ehler, W.

1973-01-01

The Debye length of an expanded plasma created by placing an evacuated chamber with an entrance slit in the path of a freely expanding laser produced plasma was measured, using the slab geometry. An independent measurement of electron density together with the observed value for the Debye length also provided a means for evaluating the plasma electron temperature. This temperature has applications in ascertaining plasma conductivity and magnetic field necessary for confinement of the laser produced plasma. Also, the temperature obtained would be useful in analyzing electron-ion recombination rates in the expanded plasma and the dynamics of the cooling process of the plasma expansion.

Filling the Holes: Work Schedulers as Job Crafters of Employment Practice in Long-Term Health Care

2016-01-01

Although work schedulers serve an organizational role influencing decisions about balancing conflicting stakeholder interests over schedules and staffing, scheduling has primarily been described as an objective activity or individual job characteristic. The authors use the lens of job crafting to examine how schedulers in 26 health care facilities enact their roles as they “fill holes” to schedule workers. Qualitative analysis of interview data suggests that schedulers expand their formal scope and influence to meet their interpretations of how to manage stakeholders (employers, workers, and patients). The authors analyze variations in the extent of job crafting (cognitive, physical, relational) to broaden role repertoires. They find evidence that some schedulers engage in rule-bound interpretation to avoid role expansion. They also identify four types of schedulers: enforcers, patient-focused schedulers, employee-focused schedulers, and balancers. The article adds to the job-crafting literature by showing that job crafting is conducted not only to create meaningful work but also to manage conflicting demands and to mediate among the competing labor interests of workers, clients, and employers.

1998-01-01

The Asociacion Demografica Salvadorena (ADS) has been working with the UN Population Fund (UNFPA) in El Salvador since November 1995 to provide sexual and reproductive health services to the country's working classes. UNFPA funding is provided through the Salvadoran government. ADS has entered the commercial and labor sectors to provide sexual and reproductive health services, and expand related public education programs to marginalized working class urban residents of El Salvador's Zona Central. The project has thus far created 25 Reproductive Health Units (UDESAR) in a number of companies, overseen by trained personnel who offer family planning and counseling services, including family planning methods, and the detection of cervical/uterine cancer, breast self-examination, HIV/STD prevention, and the determination of reproductive risk. Volunteers trained by ADS in sexual and reproductive health from a gender perspective, including decision-making and raising women's levels of self-esteem and decision-making capabilities in family planning, safe sex, and general sexual health, help project leaders by educating and motivating co-workers. ADS's involvement in promoting reproductive health in El Salvador has also given the organization an opportunity to broaden its relationship with international agencies.

Women at the top: powerful leaders define success as work + family in a culture of gender.

Cheung, Fanny M; Halpern, Diane F

2010-04-01

How do women rise to the top of their professions when they also have significant family care responsibilities? This critical question has not been addressed by existing models of leadership. In a review of recent research, we explore an alternative model to the usual notion of a Western male as the prototypical leader. The model includes (a) relationship-oriented leadership traits, (b) the importance of teamwork and consensus building, and (c) an effective work-family interface that women with family care responsibilities create and use to break through the glass ceiling. We adopted a cross-cultural perspective to highlight the importance of relational orientation and work-family integration in collectivistic cultures, which supplements models of leadership based on Western men. Our expanded model of leadership operates in the context of a "culture of gender" that defines expectations for women and men as leaders. This complex model includes women in diverse global contexts and enriches our understanding of the interplay among personal attributes, processes, and environments in leadership.

Unstructured grid adaptation is a technology that holds the potential to improve the automation and accuracy of computational fluid dynamics and other computational disciplines. Difficulty producing the highly anisotropic elements necessary for simulation on complex curved geometries that satisfies a resolution request has limited this technology's widespread adoption. The Unstructured Grid Adaptation Working Group is an open gathering of researchers working on adapting simplicial meshes to conform to a metric field. Current members span a wide range of institutions including academia, industry, and national laboratories. The purpose of this group is to create a common basis for understanding and improving mesh adaptation. We present our first major contribution: a common set of benchmark cases, including input meshes and analytic metric specifications, that are publicly available to be used for evaluating any mesh adaptation code. We also present the results of several existing codes on these benchmark cases, to illustrate their utility in identifying key challenges common to all codes and important differences between available codes. Future directions are defined to expand this benchmark to mature the technology necessary to impact practical simulation workflows.

Services to families have traditionally been delivered in a medical model. This presents challenges including workforce shortages, lack of cultural diversity, lack of training in strength-based work, and difficulty in successfully engaging and retaining families in the therapy process. The system of care (SOC) effort has worked to establish formal roles for caregivers in SOC to improve services. This paper provides an example of one community's efforts to change the SOC by expanding the roles available to caregivers in creating systems change. It describes the model developed by Communities of Care (CoC), a SOC in Central Massachusetts, and its evolution over a 10 year period. First person accounts by system partners, caregivers hired into professional roles as well as a family receiving services, demonstrate how hiring caregivers at all levels can change systems and change lives, not only for those being served but for the caregiver/professionals doing the work. It also demonstrates, however, that change at the system level is incremental, takes time, and can be fleeting unless an ongoing effort is made to support and sustain those changes.

A protocol for rat in vitro fertilization during conventional laboratory working hours.

In vitro fertilization (IVF) is a valuable technique for the propagation of experimental animals. IVF has typically been used in mice to rapidly expand breeding colonies and create large numbers of embryos. However, applications of IVF in rat breeding experiments have stalled due to the inconvenient laboratory work schedules imposed by current IVF protocols for this species. Here, we developed a new rat IVF protocol that consists of experimental steps performed during common laboratory working hours. Our protocol can be completed within 12 h by shortening the period of sperm capacitation from 5 to 1 h and the fertilization time from 10 to 8 h in human tubal fluid (HTF) medium. This new protocol generated an excellent birth rate and was applicable not only to closed colony rat strains, such as Wistar, Long-Evans, and Sprague-Dawley (SD), but also to the inbred Lewis strain. Moreover, Wistar and Long-Evans embryos prepared by this protocol were successfully frozen by vitrification and later successfully thawed and resuscitated. This protocol is practical and can be easily adopted by laboratory workers.

In this study, accurate nanostructures with various aspect ratios are created on several types of material. This work is highly applicable to the energy, optical, and nano-bio fields, for example. A silicon (Si) nano-mold is preserved using the method described, and target nanostructures are replicated reversibly and unlimitedly to or from various hard and soft materials. It is also verified that various materials can be applied to the substrates. The results confirm that the target nanostructures are successfully created in precise straight line structures and circle structures with various aspect ratios, including extremely high aspect ratios of 1:18. It is suggested that the optimal replicating and demolding process of nanostructures with high aspect ratios, which are the most problematic, could be controlled by means of the surface energy between the functional materials. Relevant numerical and analytical studies are also performed. It is possible to expand the applicability of the nanostructured mold by adopting various backing materials, including rounded substrates. The scope of the applications is extended further by transferring the nanostructures between different species of materials including metallic materials as well as identical species.

Human errors and violations in computer and information security: the viewpoint of network administrators and security specialists.

This paper describes human errors and violations of end users and network administration in computer and information security. This information is summarized in a conceptual framework for examining the human and organizational factors contributing to computer and information security. This framework includes human error taxonomies to describe the work conditions that contribute adversely to computer and information security, i.e. to security vulnerabilities and breaches. The issue of human error and violation in computer and information security was explored through a series of 16 interviews with network administrators and security specialists. The interviews were audio taped, transcribed, and analyzed by coding specific themes in a node structure. The result is an expanded framework that classifies types of human error and identifies specific human and organizational factors that contribute to computer and information security. Network administrators tended to view errors created by end users as more intentional than unintentional, while errors created by network administrators as more unintentional than intentional. Organizational factors, such as communication, security culture, policy, and organizational structure, were the most frequently cited factors associated with computer and information security.

Durability of Expanded Physician Assistant Training Positions Following the End of Health Resources and Services Administration Expansion of Physician Assistant Training Funding.

2016-09-01

The purpose of this study was to assess the number of Health Resources and Services Administration Expansion of Physician Assistant Training (EPAT)-funded physician assistant (PA) programs planning to maintain class size at expanded levels after grant funds expire and to report proposed financing methods. The 5-year EPAT grant expired in 2015, and the effect of this funding on creating a durable expansion of PA training seats has not yet been investigated. The study used an anonymous, 9-question, Web-based survey sent to the program directors at each of the PA programs that received EPAT funding. Data were analyzed in Excel and using SAS statistical analysis software for both simple percentages and for Fisher's exact test. The survey response rate was 81.48%. Eighty-two percent of responding programs indicated that they planned to maintain all expanded positions. Fourteen percent will revert to their previous student class size, and 4% will maintain a portion of the expanded positions. A majority of the 18 programs (66%) maintaining all EPAT seats will be funded by tuition pass-through, and one program (6%) will increase tuition. There was no statistical association between the program type and the decision to maintain expanded positions (P = .820). This study demonstrates that the one-time EPAT PA grant funding opportunity created a durable expansion in PA training seats. Future research should focus on the effectiveness of the program in increasing the number of graduates choosing to practice in primary care and the durability of expansion several years after funding expiration.

[Geriatric nursing staff retention. Opportunities, potentials, and strategies].

Joost, A

2013-08-01

Retaining geriatric nurses in their line of work could be an important strategy to prevent the shortage of skilled staff in the future. A prerequisite for this is detailed knowledge of the length and structure of professional careers. The IWAK ( Institut für Wirtschaft, Arbeit und Kultur) evaluated data from the German Social Insurance and carried out a structural analysis of the professional careers of geriatric nurses. Results showed that the average duration of professional careers is 20 years, of which 11.7 years constitute the period of employment and 7.8 years account for periods of inactivity. According to these findings, there is a considerable potential in extending professional careers and reducing the periods of inactivity to make better use of the existing skilled staff and to reduce staff shortage in this area. Concrete measures could involve improvement of working conditions (with the aim of avoiding long periods of inactivity and illness-related premature career endings as well as of increasing job satisfaction), creating better conditions for a good balance between work and family life, as well as setting up individual strategies to expand weekly working hours. Key players are businesses but also local authorities and politicians.

Numerical modelling of multi-vane expander operating conditions in ORC system

NASA Astrophysics Data System (ADS)

Rak, Józef; Błasiak, Przemysław; Kolasiński, Piotr

2017-11-01

Multi-vane expanders are positive displacement volumetric machines which are nowadays considered for application in micro-power domestic ORC systems as promising alternative to micro turbines and other volumetric expanders. The multi-vane expander features very simple design, low gas flow capacity, low expansion ratios, an advantageous ratio of the power output to the external dimensions and are insensitive to the negative influence of the gas-liquid mixture expansion. Moreover, the multi-vane expander can be easily hermetically sealed, which is one of the key issues in the ORC system design. A literature review indicates that issues concerning the application of multi-vane expanders in such systems, especially related to operating of multi-vane expander with different low-boiling working fluids, are innovative, not fully scientifically described and have the potential for practical implementation. In this paper the results of numerical investigations on multi-vane expander operating conditions are presented. The analyses were performed on three-dimensional numerical model of the expander in ANSYS CFX software. The numerical model of the expander was validated using the data obtained from the experiment carried out on a lab test-stand. Then a series of computational analysis were performed using expanders' numerical model in order to determine its operating conditions under various flow conditions of different working fluids.

Background Increased funding for global human immunodeficiency virus prevention and control in developing countries has created both a challenge and an opportunity for achieving long-term global health goals. This paper describes a programme in Zimbabwe aimed at responding more effectively to the HIV/AIDS epidemic by reinforcing a critical competence-based training institution and producing public health leaders. Methods The programme used new HIV/AIDS programme-specific funds to build on the assets of a local education institution to strengthen and expand the general public health leadership capacity in Zimbabwe, simultaneously ensuring that they were trained in HIV interventions. Results The programme increased both numbers of graduates and retention of faculty. The expanded HIV/AIDS curriculum was associated with a substantial increase in trainee projects related to HIV. The increased number of public health professionals has led to a number of practically trained persons working in public health leadership positions in the ministry, including in HIV/AIDS programmes. Conclusion Investment of a modest proportion of new HIV/AIDS resources in targeted public health leadership training programmes can assist in building capacity to lead and manage national HIV and other public health programmes.

The Open Science Grid (OSG) ties together individual experiments’ computing power, connecting their resources to create a large, robust computing grid, this computing infrastructure started primarily as a collection of sites associated with large HEP experiments such as ATLAS, CDF, CMS, and DZero. In the years since, the OSG has broadened its focus to also address the needs of other US researchers and increased delivery of Distributed High Through-put Computing (DHTC) to users from a wide variety of disciplines via the OSG Open Facility. Presently, the Open Facility delivers about 100 million computing wall hours per year to researchers whomore » are not already associated with the owners of the computing sites, this is primarily accomplished by harvesting and organizing the temporarily unused capacity (i.e. opportunistic cycles) from the sites in the OSG.

Comparative effectiveness research (CER) is an important branch of pharmacoeconomics that systematically studies and evaluates the cost-effectiveness of medical interventions. CER plays instrumental roles in guiding government public health policy programs and insurance. Countries throughout the world use different methods of CER to help make medical decisions based on providing optimal therapy at a reduced cost. Expenses to the healthcare system continue to rise, and CER is one-way in which expenses could be curbed in the future by applying cost-effectiveness evidence to clinical decisions. China, India, South Korea, and the United Kingdom are of essential focus because these country's economies and health care expenses continue to expand. The structures and use of CER are diverse throughout these countries, and each is of prime importance. By conducting this thorough comparison of CER in different nations, strategies and organizational setups from different countries can be applied to help guide public health and medical decision-making in order to continue to expand the establishment and role of CER programs. The patient-centered medical home has been created to help reduce costs in the primary care sector and to help improve the effectiveness of therapy. Barriers to CER are also important as many stakeholders need to be able to work together to provide the best CER evidence. The advancement of CER in multiple countries throughout the world provides a possible way of reducing costs to the healthcare system in an age of expanding expenses.

2017-02-01

After participating in a group peer-review exercise at a workshop presented by Academic Medicine and MedEdPORTAL editors at the 2015 Association of American Medical Colleges Medical Education Meeting, the authors realized that the way their work group reviewed a manuscript was very different from the way by which they each would have reviewed the paper as an individual. Further, the group peer-review process yielded more robust feedback for the manuscript's authors than did the traditional individual peer-review process. This realization motivated the authors to reconvene and collaborate to write this Commentary to share their experience and propose the expanded use of group peer review in medical education scholarship.The authors consider the benefits of a peer-review process for reviewers, including learning how to improve their own manuscripts. They suggest that the benefits of a team review model may be similar to those of teamwork and team-based learning in medicine and medical education. They call for research to investigate this, to provide evidence to support group review, and to determine whether specific paper types would benefit most from team review (e.g., particularly complex manuscripts, those receiving widely disparate initial individual reviews). In addition, the authors propose ways in which a team-based approach to peer review could be expanded by journals and institutions. They believe that exploring the use of group peer review potentially could create a new methodology for skill development in research and scholarly writing and could enhance the quality of medical education scholarship.

This article introduces the reader to community psychology practice by defining the field and its key principles and then illustrating through brief case stories what community psychology practice looks like in various employment settings. An exploration of the development of the field includes a review of the competencies of community psychology practice. Finally, the emerging opportunities for community psychology practice for psychologists are outlined. Well-publicized issues such as health disparities give psychologists an opportunity to bring social problems such as racism, sexism, homophobia, and income inequality to the forefront and to create community-wide efforts to improve the ways in which people live. Community psychology practice offers psychologists a format and a set of competencies for moving forward on this work by focusing on approaches that are ecological, community centered, population based, preventive, focused on systems change and empowerment, and multidisciplinary and that bring those most affected by the issues to the heart of the decision making.

Enhancing health research capacity in developing countries is a global health priority. Understanding the orthopedic burden of disease in Latin America will require close partnership between more-developed and less-developed countries. To this end, the Osteosynthesis and Trauma Care Foundation assembled a research consortium of Latin-American orthopedic leaders. Prior to the meeting, we surveyed attendees on perceived barriers to conducting research at their institutions. During the event, working groups discussed these barriers, developed strategies for addressing them, and planned future steps for collaboration. The participants established the need for global relationships that allow colleagues from Latin America to access to training and established investigational infrastructure of North American centers to address research questions relevant to their communities. As a result of the discussion, the International Orthopaedic Multicenter Study (INORMUS) in Fracture Care was initiated. Since then, an expanded international working group, Associación de Cirujanos Traumatológicos en las Americas (ACTUAR), has been created with the purpose of promoting increased global partnership for research capacity development.

Will a catch share for whales improve social welfare?

PubMed

Smith, Martin D; Asche, Frank; Bennear, Lori S; Havice, Elizabeth; Read, Andrew J; Squires, Dale

2014-01-01

We critique a proposal to use catch shares to manage transboundary wildlife resources with potentially high non-extractive values, and we focus on the case of whales. Because whales are impure public goods, a policy that fails to capture all nonmarket benefits (due to free riding) could lead to a suboptimal outcome. Even if free riding were overcome, whale shares would face four implementation challenges. First, a whale share could legitimize the international trade in whale meat and expand the whale meat market. Second, a legal whale trade creates monitoring and enforcement challenges similar to those of organizations that manage highly migratory species such as tuna. Third, a whale share could create a new political economy of management that changes incentives and increases costs for nongovernmental organizations (NGOs) to achieve the current level of conservation. Fourth, a whale share program creates new logistical challenges for quota definition and allocation regardless of whether the market for whale products expands or contracts. Each of these issues, if left unaddressed, could result in lower overall welfare for society than under the status quo.

Diversity: creating an environment of inclusiveness.

PubMed

Swanson, Jane W

2004-01-01

Diversity is a concept that most organizations espouse but find challenging to put into practice. It is especially critical for healthcare organizations to be responsive in addressing issues of diversity related to not only employees but also clients. This article identifies the following 3 areas that must be addressed if an organization is to succeed in creating an environment where diversity and inclusiveness are honored: (1) organizations and their leaders need to be aware of their reactions "those who are different" in their organization. This awareness is critical in identifying the underlying obstacles that prevent a truly inclusive workplace; (2) organizations and their leaders need to be able to expand their perspectives allowing them to not only understand but appreciate others. These expanded perspectives can provide a potentially powerful tool for both problem solving and conflict resolution; (3) if organizations and their leaders are actively engaged in exploring options and are open to alternatives, they will find that they not only succeed in creating an environment of inclusiveness but also are in a better position to meet the needs of employees, patients, and a multicultural society.

Medical History's Moment in Art Photography (1920 to 1950): How Lejaren à Hiller and Valentino Sarra Created a Fashion for Scenes of Early Surgery.

PubMed

Hansen, Bert

2017-10-01

Two groups of black-and-white photographs are found in medical rare book rooms and the collections of historically minded physicians. They were created by artists Hiller and Sarra to bring medical history to life for members of the health professions and, to some extent, for a wider public. These were not didactic illustrations for a textbook, but elegant scenes of great figures from Antiquity to the nineteenth century, evocation not documentation even though they were based on research. As pieces of fine art, cherished in portfolios or framed on the wall, the quality prints were intended to stimulate curiosity about the achievements of the figures portrayed. While familiar to some archivists and librarians, these photographs have received almost no attention in the scholarship of medical history. Only one short article examined them in 1983. In recent years these photographers have been given new consideration by scholars of advertising and photography. Using those works and primary sources, this article expands both men's biographies, and it explores their working methods, their artistry, and their achievements. An appreciation of these photographs enlarges our understanding of the place of medical history in American culture during the first half of the twentieth century. © The Author 2017.

A Multi-Fidelity Surrogate Model for the Equation of State for Mixtures of Real Gases

NASA Astrophysics Data System (ADS)

Ouellet, Frederick; Park, Chanyoung; Koneru, Rahul; Balachandar, S.; Rollin, Bertrand

2017-11-01

The explosive dispersal of particles is a complex multiphase and multi-species fluid flow problem. In these flows, the products of detonated explosives must be treated as real gases while the ideal gas equation of state is used for the ambient air. As the products expand outward, they mix with the air and create a region where both state equations must be satisfied. One of the most accurate, yet expensive, methods to handle this problem is an algorithm that iterates between both state equations until both pressure and thermal equilibrium are achieved inside of each computational cell. This work creates a multi-fidelity surrogate model to replace this process. This is achieved by using a Kriging model to produce a curve fit which interpolates selected data from the iterative algorithm. The surrogate is optimized for computing speed and model accuracy by varying the number of sampling points chosen to construct the model. The performance of the surrogate with respect to the iterative method is tested in simulations using a finite volume code. The model's computational speed and accuracy are analyzed to show the benefits of this novel approach.

Smart rules: six ways to get people to solve problems without you.

PubMed

Morieux, Yves

2011-09-01

As the world has become more complex, companies have steadily increased their performance requirements: Now they strive to offer low prices and high quality; to customize products for local markets and standardize them for greater returns; to innovate and be efficient. The typical corporate response to such conflicting goals complicates things further: Firms restructure and try to align their organizations with extra coordinating functions, processes, and incentives. This approach does more harm than good. Managers' time gets sucked up by reports and meetings, leaving little time to work with employees. But there is a better way, says BCG senior partner Yves Morieux: Instead of strangling employees with new rules and procedures, create an environment in which they're compelled to work with one another to develop solutions to complex challenges. Managers can create this environment by applying six "smart rules": (1) improve understanding of what coworkers do and the real constraints they face, (2) determine which people are the firm's natural integrators and strengthen their roles, (3) expand the amount of power available to everyone, (4) increase the need for reciprocity in the system, (5) make employees feel the "shadow of the future," and (6) hold uncooperative people accountable. By tapping employees' ingenuity through the use of smart rules, firms can manage complexity quickly and creatively-and streamline their organizations.

Theoretical investigation of flash vaporisation in a screw expander

NASA Astrophysics Data System (ADS)

Vasuthevan, Hanushan; Brümmer, Andreas

2017-08-01

In the present study flash vaporisation of liquid injection in a twin screw expander for a Trilateral Flash Cycle (TFC) is examined theoretically. The TFC process comprises a pressure increase in the working fluid, followed by heating the liquid close to boiling point. The hot liquid is injected into the working chamber of a screw expander. During this process the pressure of the liquid drops below the saturation pressure, while the temperature of the liquid remains virtually constant. Hence the liquid is superheated and in a metastable state. The liquid jet seeks to achieve a stable state in thermodynamic equilibrium and is therefore partially vaporised. This effect is referred to as flash vaporisation. Accordingly, a two-phase mixture, consisting of vapour and liquid, exists in the working chamber. Thermodynamic simulations were carried out using water as the working fluid for representative screw expander geometry. The simulations presented are performed from two different aspects during the filling process of a screw expander. The first case is the vaporisation of the injected liquid in a state of thermodynamic equilibrium, whereby the two-phase mixture is treated entirely as a compressible and homogeneous gas. The second case considers flashing efficiency. It describes the quantity of flashed vapour and consists of a liquid and vapour domain. Both models are compared and analysed with respect to the operational behaviour of a screw expander.

The Omega EP laser (1000 J in 10 ps pulses) was used to investigate a relativistic intensity laser interaction with near-critical density plasma using a transverse proton beam to diagnose the large electromagnetic fields generated. A very low density foam target mounted in a washer provided the near-critical density conditions. The fields from a scaled, two-dimensional particle-in-cell simulation were inputed into a particle-tracking code to create simulated proton probe images. This allows us to understand the origins of the complex features in the experimental images, including a rapidly expanding sheath field, evidence for ponderomotive channeling and fields at the foam-washer interface. This material is based upon work supported by the Department of Energy National Nuclear Security Administration under Award Number DE-NA0002028.

Surface charge method for molecular surfaces with curved areal elements I. Spherical triangles

NASA Astrophysics Data System (ADS)

Yu, Yi-Kuo

2018-03-01

Parametrizing a curved surface with flat triangles in electrostatics problems creates a diverging electric field. One way to avoid this is to have curved areal elements. However, charge density integration over curved patches appears difficult. This paper, dealing with spherical triangles, is the first in a series aiming to solve this problem. Here, we lay the ground work for employing curved patches for applying the surface charge method to electrostatics. We show analytically how one may control the accuracy by expanding in powers of the the arc length (multiplied by the curvature). To accommodate not extremely small curved areal elements, we have provided enough details to include higher order corrections that are needed for better accuracy when slightly larger surface elements are used.

The US Virtual Herbarium: working with individual herbaria to build a national resource.

2012-01-01

The goal of the US Virtual Herbarium (USVH) project is to digitize (database, image, georeference) all specimens in all US herbaria, enabling them to be made available through a single portal. Herbaria house specimens of plants, fungi, and algae, so USVH will offer a rich portrait of biodiversity in the US and in the other countries represented in US herbaria. Equally importantly, working towards this goal will engage people with herbaria and the organisms they house, expanding their appreciation of both the power of biodiversity informatics and the demands that it places on data providers while developing improved communication among those working in and with herbaria. The project is not funded but has strong support among those working in herbaria. It works through regional herbarium networks, some of which existed prior to the USVH project, while others are still in gestation. It differs from most digitization projects in its emphasis on helping those involved with herbaria become part of a national enterprise, an aspect that is seen as critical to creating the resources needed to develop and sustain the project. In this paper, we present some of the lessons we have learned and the difficulties we have encountered during the first few years of the project.

Recent studies have shown that fluctuations of various types play important roles in the evolution of the fireball created in relativistic heavy ion collisions and bear many phenomenological consequences for experimental observables. In addition, the bulk dynamics of the fireball is well described by relativistic hydrodynamic expansion and the fluctuations on top of such expanding background can be studied within the linearized hydrodynamic framework. In this paper we present complete and analytic sound wave solutions on top of both Bjorken flow and Hubble flow backgrounds.

Short hairpin RNA (shRNA) libraries are limited by the low efficacy of many shRNAs, giving false negatives, and off-target effects, giving false positives. Here we present a strategy for rapidly creating expanded shRNA pools (∼30 shRNAs/gene) that are analyzed by deep-sequencing (EXPAND). This approach enables identification of multiple effective target-specific shRNAs from a complex pool, allowing a rigorous statistical evaluation of whether a gene is a true hit. PMID:19448642

Drainage with metallic stents is the treatment of choice in malignant obstructive jaundice. Technical and clinical success with metallic stents is obtained in over 90% and 80% of cases, respectively. There are self-expandable metallic stents designed to increase permeability. The aim of this study was to describe the results obtained with totally covered self-expandable and uncovered self-expandable metallic stents in the palliative treatment of malignant biliary obstruction. Sixty eight patients with malignant obstructive jaundice secondary to pancreatobiliary or metastatic disease not amenable to surgery were retrospectively included. Two groups were created: group A (covered self-expandable metallic stents) (n = 22) and group B (uncovered self-expandable metallic stents) (n = 46). Serum total bilirubin, direct bilirubin, alkaline phosphatase and gamma glutamyl transferase levels decreased in both groups and no statistically significant difference was detected (p = 0.800, p = 0.190, p = 0.743, p = 0.521). Migration was greater with covered stents but it was not statistically significant either (p = 0.101). Obstruction was greater in the group with uncovered stents but it was not statistically significant either (p = 0.476). There are no differences when using covered self-expandable stents or uncovered self-expandable stents in terms of technical and clinical success or complications in the palliative treatment of malignant obstructive jaundice.

Organigraphs: drawing how companies really work.

PubMed

Mintzberg, H; Van der Heyden, L

1999-01-01

Walk into any organization and you will get a snapshot of the company in action--people and products moving every which way. But ask for a picture of the company and you will be given the org chart, with its orderly little boxes showing just the names and titles of managers. Now there's a more revealing way to depict the people and operations within an organization--an approach called the organigraph. The organigraph is not a chart. It's a map that offers an overview of the company's functions and the ways that people organize themselves at work. Perhaps most important, an organigraph can help managers see untapped competitive opportunities. Drawing on the organigraphs they created for about a dozen companies, authors Mintzberg and Van der Heyden illustrate just how valuable a tool the organigraph is. For instance, one they created for Electrocomponents, a British distributor of electrical and mechanical items, led managers to a better understanding of the company's real expertise--business-to-business relationships. As a result of that insight, the company wisely decided to expand in Asia and to increase its Internet business. As one manager says, "It allowed the company to see all sorts of new possibilities." With traditional hierarchies vanishing and newfangled--and often quite complex--organizational forms taking their place, people are struggling to understand how their companies work. What parts connect to one another? How should processes and people come together? Whose ideas have to flow where? With their flexibility and realism, organigraphs give managers a new way to answer those questions.

Cultural brokerage: Creating linkages between voices of lifeworld and medicine in cross-cultural clinical settings.

PubMed

Lo, Ming-Cheng Miriam

2010-09-01

Culturally competent healthcare has emerged as a policy solution to racial and ethnic health disparities in the United States. Current research indicates that patient-centered care is a central component of culturally competent healthcare, and a rich literature exists on how to elicit patients' lifeworld voices through open-ended questions, sensitive communication skills, and power-sharing interaction styles. But it remains largely unclear how doctors create linkages between cultures of medicine and lifeworld as two sets of incongruent meaning systems. Without such linkages, a doctor lacks the cultural tool to incorporate her patient's assumptions or frameworks into the voice of medicine, rendering it difficult to (at least partially) expand and transform the latter from within. This study explores how doctors perform this bridging work, conceptualized as cultural brokerage, on the job. Cultural brokerage entails mutual inclusion of different sets of schemas or frameworks with which people organize their meanings and information. Based on 24 in-depth interviews with primary care physicians in Northern California, this study inductively documents four empirical mechanisms of cultural brokerage: 'translating between health systems', 'bridging divergent images of medicine', 'establishing long-term relationships', and 'working with patients' relational networks'. Furthermore, the study argues that cultural brokerage must be understood as concrete 'cultural labor', which involves specific tasks and requires time and resources. I argue that the performance of cultural brokerage work is embedded in the institutional contexts of the clinic and therefore faces two macro-level constraints: the cultural ideology and the political economy of the American healthcare system.

Harm reduction and “Clean” community: can Viet Nam have both?

PubMed Central

2012-01-01

The findings of our research show that while police play multiple roles in the fight against drug-related crime, they often perceived their tasks – especially preventing and controlling drug use on the one hand, and supporting harm reduction on the other – as contradictory, and this creates tensions in their work and relations with their communities. Although they are leaders and implementers of harm reduction, not all police know about it, and some remain skeptical or perceive it as contradictory to their main task of fighting drugs. Methadone treatment is seen by some as in competition with their main task of coordinating conventional drug treatment in the rehabilitation center. The history of drug use and the evolution of discourses on drug use in Viet Nam have created these conflicting pressures on police, and thus created contradictory expectations and led to different views and attitudes of police regarding various harm reduction measures. This might aid understanding why, despite the comprehensive and progressive policies on HIV/AIDS and harm reduction in Viet Nam, it is not easy for police to actively and effectively support and be involved in harm reduction at the ground level. To promote the wider acceptance of harm reduction the concept of community safety must be expanded to include community health; harm reduction must be integrated into the “new society” movement; and laws and policies need further revision to reduce contradiction between current drug laws and HIV laws. Harm reduction guidelines for police and other actors need to be disseminated and supported, embodying better ways of working between sectors, and all sectors in the partnership require support for building capacity to contribute to the overall goal.

[Structural Equation Modeling of Quality of Work Life in Clinical Nurses based on the Culture-Work-Health Model].

Kim, Miji; Ryu, Eunjung

2015-12-01

The purpose of this study was to construct and test a structural equation model of quality of work life for clinical nurses based on Peterson and Wilson's Culture-Work-Health model (CWHM). A structured questionnaire was completed by 523 clinical nurses to analyze the relationships between concepts of CWHM-organizational culture, social support, employee health, organizational health, and quality of work life. Among these conceptual variables of CWHM, employee health was measured by perceived health status, and organizational health was measured by presenteeism. SPSS21.0 and AMOS 21.0 programs were used to analyze the efficiency of the hypothesized model and calculate the direct and indirect effects of factors affecting quality of work life among clinical nurses. The goodness-of-fit statistics of the final modified hypothetical model are as follows: χ²=586.03, χ²/df=4.19, GFI=.89, AGFI=.85, CFI=.91, TLI=.90, NFI=.89, and RMSEA=.08. The results revealed that organizational culture, social support, organizational health, and employee health accounted for 69% of clinical nurses' quality of work life. The major findings of this study indicate that it is essential to create a positive organizational culture and provide adequate organizational support to maintain a balance between the health of clinical nurses and the organization. Further repeated and expanded studies are needed to explore the multidimensional aspects of clinical nurses' quality of work life in Korea, including various factors, such as work environment, work stress, and burnout.

The poverty-related neglected diseases: Why basic research matters.

Hotez, Peter J

2017-11-01

Together, malaria and the neglected tropical diseases (NTDs) kill more than 800,000 people annually, while creating long-term disability in millions more. International support for mass drug administration, bed nets, and other preventive measures has resulted in huge public health gains, while support for translational research is leading to the development of some new neglected disease drugs, diagnostics, and vaccines. However, funding for basic science research has not kept up, such that we are missing opportunities to create a more innovative pipeline of control tools for parasitic and related diseases. There is an urgent need to expand basic science approaches for neglected diseases, especially in the areas of systems biology and immunology; ecology, evolution, and mathematical biology; functional and comparative OMICs; gene editing; expanded use of model organisms; and a new single-cell combinatorial indexing RNA sequencing approach. The world's poor deserve access to innovation for neglected diseases. It should be considered a fundamental human right.

Expanding services in a shrinking economy: desktop document delivery in a dental school library.

PubMed

Gushrowski, Barbara A

2011-07-01

How can library staff develop and promote a document delivery service and then expand the service to a wide audience? The setting is the library at the Indiana University School of Dentistry (IUSD), Indianapolis. A faculty survey and a citation analysis were conducted to determine potential use of the service. Volume of interlibrary loan transactions and staff and equipment capacity were also studied. IUSD Library staff created a desktop delivery service (DDSXpress) for faculty and then expanded the service to practicing dental professionals and graduate students. The number of faculty using DDSXpress remains consistent. The number of practicing dental professionals using the service is low. Graduate students have been quick to adopt the service. Through careful analysis of capacity and need for the service, staff successfully expanded document delivery service without incurring additional costs. Use of DDSXpress is continually monitored, and opportunities to market the service to practicing dental professionals are being investigated.

Abrahamsson, Peter; Isaksson, Sten; Andersson, Gunilla

2011-11-01

To evaluate the space-maintaining capacity of titanium mesh covered by a collagen membrane after soft tissue expansion on the lateral border of the mandible in rabbits, and to assess bone quantity and quality using autogenous particulate bone or bone-substitute (Bio-Oss(®) ), and if soft tissue ingrowth can be avoided by covering the mesh with a collagen membrane. In 11 rabbits, a self-inflatable soft tissue expander was placed under the lateral mandibular periosteum via an extra-oral approach. After 2 weeks, the expanders were removed and a particulated onlay bone graft and deproteinized bovine bone mineral (DBBM) (Bio-Oss(®) ) were placed in the expanded area and covered by a titanium mesh. The bone and DBBM were separated in two compartments under the mesh with a collagen membrane in between. The mesh was then covered with a collagen membrane. After 3 months, the animals were sacrificed and specimens were collected for histology. The osmotic soft tissue expander created a subperiosteal pocket and a ridge of new bone formed at the edges of the expanded periosteum in all sites. After the healing period of 3 months, no soft tissue dehiscence was recorded. The mean bone fill was 58.1±18% in the bone grafted area and 56.9±13.7% in the DBBM area. There was no significant difference between the autologous bone graft and the DDBM under the titanium mesh with regard to the total bone area or the mineralized bone area. Scanning electron microscopy showed that new bone was growing in direct contact with the DBBM particles and the titanium mesh. There is a soft tissue ingrowth even after soft tissue expansion and protection of the titanium mesh with a collagen membrane. This study confirms that an osmotic soft tissue expander creates a surplus of periosteum and soft tissue, and that new bone can subsequently be generated under a titanium mesh with the use of an autologous bone graft or DBBM. © 2011 John Wiley & Sons A/S.

SU-C-BRB-01: Development of Dynamic Gimbaled X-Ray Head Swing Irradiation Technique

DOE Office of Scientific and Technical Information (OSTI.GOV)

Ono, T; Miyabe, Y; Yokota, K

Purpose: The Vero4DRT has a unique gimbaled x-ray head with rotating around orthogonal two axes. The purpose of this study was to develop a new irradiation technique using the dynamic gimbaled x-ray head swing function. Methods: The Vero4DRT has maximum field size of 150Χ150 mm2. The expanded irradiation field (expanded-field) for the longitudinal direction which is vertical to the MLC sliding direction, was created by the MLC motion and the gimbaled x-ray head rotation. The gimbaled x-ray head was rotated ± 35 mm, and the expanded-field size was set as 150Χ220 mm2. To irradiate uniform dose distribution, the diamond-shaped radiationmore » field was created and continuously moved for the longitudinal direction. It was achieved by combination of opening and closing of the MLC and gimbal swing rotation. To evaluate dosimetric characteristic of the expanded-field, films inserted in water-equivalent phantoms at 100 mm depth were irradiated and the field size, penumbra, flatness and symmetry were analyzed.In addition, the expanded-field irradiation technique was applied to virtual wedge irradiation. Wedged beam was acquired with the delta–shaped radiation field. 150Χ 220 mm2 fields with 15, 30, 45, and 60 degree wedge were examined. The wedge angles were measured with irradiated film and compared with assumed wedge angles. Results: The field size, penumbra, flatness and symmetry of the expanded-field were 150.0 mm, 8.1–8.4 mm, 2.8% and −0.8% for the lateral direction and 220.1 mm, 6.3–6.4 mm, 3.2% and −0.4% for the longitudinal direction at 100 mm depth. The measured wedge angles were 15.1, 30.2, 45.2 and 60.2 degrees. The differences between assumed and measured angles were within 0.2 degrees. Conclusion: A new technique of the gimbal swing irradiation was developed. To extend applied targets, especially for whole breast irradiation, the expanded-field and virtual wedge irradiations would be effective.« less

The Collaborative Forest Landscape Restoration Program (CFLRP), established in 2009, encourages collaborative landscape scale ecosystem restoration efforts on United States Forest Service (USFS) lands. Although the USFS employees have experience engaging in collaborative planning, CFLRP requires collaboration in implementation, a domain where little prior experience can be drawn on for guidance. The purpose of this research is to identify the ways in which CFLRP's collaborative participants and agency personnel conceptualize how stakeholders can contribute to implementation on landscape scale restoration projects, and to build theory on dynamics of collaborative implementation in environmental management. This research uses a grounded theory methodology to explore collaborative implementation from the perspectives and experiences of participants in landscapes selected as part of the CFLRP in 2010. Interviewees characterized collaborative implementation as encompassing three different types of activities: prioritization, enhancing treatments, and multiparty monitoring. The paper describes examples of activities in each of these categories and then identifies ways in which collaborative implementation in the context of CFLRP (1) is both hindered and enabled by overlapping legal mandates about agency collaboration, (2) creates opportunities for expanded accountability through informal and relational means, and, (3) creates feedback loops at multiple temporal and spatial scales through which monitoring information, prioritization, and implementation actions shape restoration work both within and across projects throughout the landscape creating more robust opportunities for adaptive management.

A Baccalaureate Education Curriculum to Prepare Dental Hygienists for Expanded Public Health Practice.

PubMed

Rowley, Lisa J; Stein, Susan M

2016-06-01

A baccalaureate dental hygiene education program was intentionally designed and implemented to prepare dental hygienists to work in expanded public health practice. Expanded practice dental hygienists (EPDH) in Oregon practice without the supervision of a dentist to provide dental hygiene services for underserved patients with limited access to dental care. Ten competencies were identified for the successful EPDH, and then these competencies were incorporated into the curriculum of a baccalaureate dental hygiene program. When recent graduates of the innovative program were surveyed, results indicated that they felt well prepared for expanded practice, they had a high level of interest in working as an EPDH, and all were planning to apply for an expanded practice permit. Two graduates and their unique contributions to individuals in need are profiled. Intentional preparation of dental hygienists for expanded public health roles suggested the need for a baccalaureate curriculum designed specifically for that purpose. Advocacy and collaboration among educators, legislators, and administrators in Oregon led to the development and implementation of such an innovative dental hygiene education program at Pacific University. Graduates are likely to pursue opportunities working as EPDHs. Further research will document the viability of this purposefully designed curriculum to prepare dental hygienists to help meet the public need for optimal oral health. Copyright © 2016 Elsevier Inc.

Slot Nozzle Effects for Reduced Sonic Boom on a Generic Supersonic Wing Section

NASA Technical Reports Server (NTRS)

Caster, Raymond S.

2010-01-01

NASA has conducted research programs to reduce or eliminate the operational restrictions of supersonic aircraft over populated areas. Restrictions are due to the disturbance from the sonic boom, caused by the coalescence of shock waves formed off the aircraft. Results from two-dimensional computational fluid dynamic (CFD) analyses (performed on a baseline Mach 2.0 nozzle in a simulated Mach 2.2 flow) indicate that over-expanded and under-expanded operation of the nozzle has an effect on the N-wave boom signature. Analyses demonstrate the feasibility of reducing the magnitude of the sonic boom N-wave by controlling the nozzle plume interaction with the nozzle boat tail shock structure. This work was extended to study the impact of integrating a high aspect ratio exhaust nozzle or long slot nozzle on the trailing edge of a supersonic wing. The nozzle is operated in a highly under-expanded condition, creating a large exhaust plume and a shock at the trailing edge of the wing. This shock interacts with and suppresses the expansion wave caused by the wing, a major contributor to the sonic boom signature. The goal was to reduce the near field pressures caused by the expansion using a slot nozzle located at the wing trailing edge. Results from CFD analysis on a simulated wing cross-section and a slot nozzle indicate potential reductions in sonic boom signature compared to a baseline wing with no propulsion or trailing edge exhaust. Future studies could investigate if this effect could be useful on a supersonic aircraft for main propulsion, auxiliary propulsion, or flow control.

Membrane dominated space structures are lightweight and package efficiently for launch; however, they must be expanded (deployed) in-orbit to achieve the desired geometry. These expandable structural systems include solar sails, solar power arrays, antennas, and numerous other large aperture devices that are used to collect, reflect and/or transmit electromagnetic radiation. In this work, an integrated approach to development of thin-film damage tolerant membranes is explored using advanced manufacturing. Bio-inspired hierarchical structures were printed on films using additive manufacturing to achieve improved tear resistance and to facilitate membrane deployment. High precision, robust expandable structures can be realized using materials that are both space durable and processable using additive manufacturing. Test results show this initial work produced higher tear resistance than neat film of equivalent mass. Future research and development opportunities for expandable structural systems designed using an integrated approach to structural design, manufacturing, and materials selection are discussed.

Weatherford, Barbara; Bower, Kathleen A; Vitello-Cicciu, Joan

Although innovation is critical to success in today's tumultuous environment, health care is slow to embrace it, and there is significant variability in strategic adoption of innovation across organizations. Nurse leaders do not need to be innovators themselves but must engage in, and have the ability to create, an organizational culture of innovation. Twenty-six leadership behaviors specific to innovation leadership were identified through a Delphi study to develop competencies as well as the knowledge, skills, and attitudes that support nurse leaders in acquiring or expanding the capability of nurse leaders to create a culture of innovation. It was demonstrated that nursing innovation experts were able to differentiate between general leadership behaviors and innovation leader behaviors. In addition, the need to acquire basic leadership competencies before mastering innovation leader competencies was identified. Five strategies to initiate or expand a culture of innovation in organizations were identified, including (1) assessment of organizational capacity for innovation; (2) acknowledgement of the responsibility of all leaders to create an innovation-rich environment; (3) provision of education, skill building, and coaching; (4) encouragement of an ongoing practice of innovation, even in the face of failure; and (5) development of a sustainable culture of innovation.

Landslides and floods of lava and water tremendously affected the Columbia River during its long history of transecting the Cascade Volcanic Arc. This field trip touches on aspects of the resulting geology of the scenic Columbia River Gorge, including the river-blocking Bonneville landslide of ~550 years ago and the great late- Pleistocene Missoula floods. Not only did these events create great landscapes, but they inspired great geologists. Mid-nineteenth century observations of the Columbia River and Pacific Northwest by James Dwight Dana and John Strong Newberry helped germinate the “school of fluvial” erosion later expanded upon by the southwestern United States topographic and geologic surveys. Later work on features related to the Missoula floods framed the career of J Harlen Bretz in one of the great geologic controversies of the twentieth century.

The universality of gravity (1 g) in our daily lives makes it difficult to appreciate its importance in morphology and physiology. Bone and muscle support systems were created, cellular pumps developed, neurons organised and receptors and transducers of gravitational force to biologically relevant signals evolved under 1g gravity. Spaceflight provides the only microgravity environment where systematic experimentation can expand our basic understanding of gravitational physiology and perhaps provide new insights into normal physiology and disease processes. These include the surprising extent of our body's dependence on perceptual information, and understanding the effect and importance of forces generated within the body's weightbearing structures such as muscle and bones. Beyond this exciting prospect is the importance of this work towards opening the solar system for human exploration. Although both appear promising, we are only just beginning to taste what lies ahead.

Global health education (GHE) continues to be a growing initiative in many medical schools across the world. This focus is no longer limited to participants from high-income countries and has expanded to institutions and students from low- and middle-income settings. With this shift has come a need to develop meaningful curricula through engagement between educators and learners who represent the sending institutions and the diverse settings in which GHE takes place. The Bellagio Global Health Education Initiative (BGHEI) was founded to create a space for such debate and discussion and to generate guidelines towards a universal curriculum for global health. In this article, we describe the development and process of our work and outline six overarching principles that ought to be considered when adopting an inclusive approach to GHE curriculum development.

Analysis and optimization of the active rigidity joint

NASA Astrophysics Data System (ADS)

Manzo, Justin; Garcia, Ephrahim

2009-12-01

The active rigidity joint is a composite mechanism using shape memory alloy and shape memory polymer to create a passively rigid joint with thermally activated deflection. A new model for the active rigidity joint relaxes constraints of earlier methods and allows for more accurate deflection predictions compared to finite element results. Using an iterative process to determine the strain distribution and deflection, the method demonstrates accurate results for both surface bonded and embedded actuators with and without external loading. Deflection capabilities are explored through simulated annealing heuristic optimization using a variety of cost functions to explore actuator performance. A family of responses presents actuator characteristics in terms of load bearing and deflection capabilities given material and thermal constraints. Optimization greatly expands the available workspace of the active rigidity joint from the initial configuration, demonstrating specific work capabilities comparable to those of muscle tissue.

The advent of high-throughput technology like microarrays has provided the platform for studying how different cellular components work together, thus created an enormous interest in mathematically modeling biological network, particularly gene regulatory network (GRN). Of particular interest is the modeling and inference on time-series data, which capture a more thorough picture of the system than non-temporal data do. We have given an extensive review of methodologies that have been used on time-series data. In realizing that validation is an impartible part of the inference paradigm, we have also presented a discussion on the principles and challenges in performance evaluation of different methods. This survey gives a panoramic view on these topics, with anticipation that the readers will be inspired to improve and/or expand GRN inference and validation tool repository. PMID:20190956

Abstract Two conferences, Creating More Compassionate Systems of Care (November 2012) and On Improving the Spiritual Dimension of Whole Person Care: The Transformational Role of Compassion, Love and Forgiveness in Health Care (January 2013), were convened with the goals of reaching consensus on approaches to the integration of spirituality into health care structures at all levels and development of strategies to create more compassionate systems of care. The conferences built on the work of a 2009 consensus conference, Improving the Quality of Spiritual Care as a Dimension of Palliative Care. Conference organizers in 2012 and 2013 aimed to identify consensus-derived care standards and recommendations for implementing them by building and expanding on the 2009 conference model of interprofessional spiritual care and its recommendations for palliative care. The 2013 conference built on the 2012 conference to produce a set of standards and recommended strategies for integrating spiritual care across the entire health care continuum, not just palliative care. Deliberations were based on evidence that spiritual care is a fundamental component of high-quality compassionate health care and it is most effective when it is recognized and reflected in the attitudes and actions of both patients and health care providers.

ABSTRACT PROBLEM BEING ADDRESSED Patient care is poorly coordinated between family physicians and the cancer system and the working relationships are not strong. OBJECTIVE OF PROGRAM To improve integration of patient care and communication between FPs and cancer specialists; enhance FPs’ knowledge of cancer and the cancer system; and promote the role of primary care within the cancer care system. PROGRAM DESCRIPTION The Uniting Primary Care and Oncology (UPCON) Network of CancerCare Manitoba has created partnerships with 12 primary care clinics in Winnipeg, Man, by providing the following: access to the provincial electronic medical record for cancer; small group continuing professional development for a “lead physician” from each clinic to make him or her the local cancer resource; educational outreach to all clinic staff; and changes within CancerCare Manitoba to highlight the role of FPs. CONCLUSION Lead physicians are appreciated by their clinic colleagues, and these FPs are the main users of the cancer electronic medical record. A strong cancer continuing professional development program has been implemented and a voice for primary care has been created within the agency. The UPCON Network is now expanding throughout Manitoba. PMID:19282538

Strack, Robert W; Orsini, Muhsin Michael; Fearnow-Kenney, Melodie; Herget, Jennifer; Milroy, Jeffrey J; Wyrick, David L

Information and communication technologies are opening up vast new arenas for conducting the work of health promotion. Technology-based health promotions expand reach, standardize information and its delivery, provide opportunities for tailoring, create engaging interactivity within content delivery, provide for privacy and autonomy, improve portability, and lower delivery costs. This commentary describes the ongoing exploration and development of a web-based tool for enhancing the reach and impact of photovoice as a community change intervention. Features of the tool use information and communication technologies that integrate the use of an online learning management system, tailored messaging, gaming technology, interactive features, and the application of social media's power to increase the capacity of communities to employ comprehensive strategies to improve the health of their communities. It will enable individuals and groups to use photos and captions to assess the physical environment, social norms and behaviors of communities; raise community awareness of the factors contributing to ill-health in their communities, mobilize stakeholders, and inform environmental strategies and policy changes. We believe it will enhance the delivery of educational content about conducting photovoice projects, provide features unavailable without the application of information and communication technologies, and will be substantive advancement over existing photovoice resources.

Optical Potential Field Mapping System

NASA Technical Reports Server (NTRS)

Reid, Max B. (Inventor)

1996-01-01

The present invention relates to an optical system for creating a potential field map of a bounded two dimensional region containing a goal location and an arbitrary number of obstacles. The potential field mapping system has an imaging device and a processor. Two image writing modes are used by the imaging device, electron deposition and electron depletion. Patterns written in electron deposition mode appear black and expand. Patterns written in electron depletion mode are sharp and appear white. The generated image represents a robot's workspace. The imaging device under processor control then writes a goal location in the work-space using the electron deposition mode. The black image of the goal expands in the workspace. The processor stores the generated images, and uses them to generate a feedback pattern. The feedback pattern is written in the workspace by the imaging device in the electron deposition mode to enhance the expansion of the original goal pattern. After the feedback pattern is written, an obstacle pattern is written by the imaging device in the electron depletion mode to represent the obstacles in the robot's workspace. The processor compares a stored image to a previously stored image to determine a change therebetween. When no change occurs, the processor averages the stored images to produce the potential field map.

[Determine and Implement Updates to Be Made to MODEAR (Mission Operations Data Enterprise Architecture Repository)

NASA Technical Reports Server (NTRS)

Fanourakis, Sofia

2015-01-01

My main project was to determine and implement updates to be made to MODEAR (Mission Operations Data Enterprise Architecture Repository) process definitions to be used for CST-100 (Crew Space Transportation-100) related missions. Emphasis was placed on the scheduling aspect of the processes. In addition, I was to complete other tasks as given. Some of the additional tasks were: to create pass-through command look-up tables for the flight controllers, finish one of the MDT (Mission Operations Directorate Display Tool) displays, gather data on what is included in the CST-100 public data, develop a VBA (Visual Basic for Applications) script to create a csv (Comma-Separated Values) file with specific information from spreadsheets containing command data, create a command script for the November MCC-ASIL (Mission Control Center-Avionics System Integration Laboratory) testing, and take notes for one of the TCVB (Terminal Configured Vehicle B-737) meetings. In order to make progress in my main project I scheduled meetings with the appropriate subject matter experts, prepared material for the meetings, and assisted in the discussions in order to understand the process or processes at hand. After such discussions I made updates to various MODEAR processes and process graphics. These meetings have resulted in significant updates to the processes that were discussed. In addition, the discussions have helped the departments responsible for these processes better understand the work ahead and provided material to help document how their products are created. I completed my other tasks utilizing resources available to me and, when necessary, consulting with the subject matter experts. Outputs resulting from my other tasks were: two completed and one partially completed pass through command look-up tables for the fight controllers, significant updates to one of the MDT displays, a spreadsheet containing data on what is included in the CST-100 public data, a tool to create a csv file with specific information from spreadsheets containing command data, a command script for the November MCC-ASIL testing which resulted in a successful test day identifying several potential issues, and notes from one of the TCVB meetings that was used to keep the teams up to date on what was discussed and decided. I have learned a great deal working at NASA these last four months. I was able to meet and work with amazing individuals, further develop my technical knowledge, expand my knowledge base regarding human spaceflight, and contribute to the CST-100 missions. My work at NASA has strengthened my desire to continue my education in order to make further contributions to the field, and has given me the opportunity to see the advantages of a career at NASA.

A Multi-Fidelity Surrogate Model for Handling Real Gas Equations of State

NASA Astrophysics Data System (ADS)

Ouellet, Frederick; Park, Chanyoung; Rollin, Bertrand; Balachandar, S."bala"

2016-11-01

The explosive dispersal of particles is an example of a complex multiphase and multi-species fluid flow problem. This problem has many engineering applications including particle-laden explosives. In these flows, the detonation products of the explosive cannot be treated as a perfect gas so a real gas equation of state is used to close the governing equations (unlike air, which uses the ideal gas equation for closure). As the products expand outward from the detonation point, they mix with ambient air and create a mixing region where both of the state equations must be satisfied. One of the more accurate, yet computationally expensive, methods to deal with this is a scheme that iterates between the two equations of state until pressure and thermal equilibrium are achieved inside of each computational cell. This work strives to create a multi-fidelity surrogate model of this process. We then study the performance of the model with respect to the iterative method by performing both gas-only and particle laden flow simulations using an Eulerian-Lagrangian approach with a finite volume code. Specifically, the model's (i) computational speed, (ii) memory requirements and (iii) computational accuracy are analyzed to show the benefits of this novel modeling approach.

Rethinking the Way We Do Research: The Benefits of Community-Engaged, Citizen Science Approaches and Nontraditional Collaborators.

PubMed

Dick, Danielle M

2017-11-01

There is tremendous opportunity for basic scientists to enhance the impact of our research by engaging more deeply with nontraditional partners and expanding the way we think about interdisciplinary research teams. These efforts can include more deeply engaging our participants, and the broader public, in our research; working with individuals from other fields to take a more active role in the dissemination and translation of our research; and working with collaborators from the arts and communication sciences to make our research more engaging and understandable. In this review, I provide an overview of our efforts along these lines in a project called Spit for Science (https://spit4science.vcu.edu/). This project draws from concepts central to community-engaged participatory research and citizen science. Although conducting research in this way involves a considerable time commitment, it has many potential benefits, including raising awareness about our research areas and findings; creating a public that is more connected to and aware of the importance of research, which can have potential implications for funding for science; creating new job opportunities for students; and increasing participation rates in our studies. By thinking creatively about how we conduct our research, and more broadly engaging diverse groups of individuals in the research process, we have the potential to significantly increase the reach and impact of our science.

Ridge expansion and immediate placement with piezosurgery and screw expanders in atrophic maxillary sites: two case reports.

PubMed

Kelly, Andrew; Flanagan, Dennis

2013-02-01

Endosseous dental implants may require bone augmentation before implant placement. Herein is described an approach to edentulous ridge expansion with the use of piezosurgery and immediate placement of implants. This may allow for a shortened treatment time and the elimination of donor-site morbidity. Two cases are reported. This technique uses a piezoelectric device to cut the crestal and proximal facial cortices. Space is then created with motorized osteotomes to widen the split ridge. This technique allows for expansion of narrow, anatomically limiting, atrophic ridges, creating space for immediate implant placement. The facial and lingual cortices provide support with vital osteocytes for osteogenesis. The 2 patients presented had adequate bone height for implant placement but narrow edentulous ridges. In patient 1 at site #11, the ridge crest was 3.12 mm thick and was expanded to accept a 4.3 mm × 13 mm implant. The resulting ridge width was 8.88 mm, which was verified using cone beam computerized tomography (CBCT). In patient 2 at site #8 and site #9, the narrow ridge was expanded using the same technique to accept 2 adjacent 3.5 mm × 14 mm implants. The implants were restored to a functional and esthetic outcome.

The Dark Skies, Bright Kids (DSBK) outreach program brings astronomy education into local elementary schools in central Virginia's Southern Albemarle County through an after-school club. Taking advantage of the unusually dark night skies in the rural countryside, DSBK targets economically disadvantaged schools that tend to be underserved due to their rural locale. The goals of DSBK are to foster children's natural curiosity, demonstrate that science is a fun and creative process, challenge students' conceptions of what a scientist is and does, and teach some basic astronomy. Furthermore, DSBK works to assimilate families into students' education by holding family observing nights at the school. Now in its third semester, DSBK has successfully run programs at two schools with very diverse student populations. Working with these students has helped us to revise our activities and to create new ones. A by-product of our work has been the development of lesson plans, complete with learning goals and detailed instructions, that we make publically available on our website. This year we are expanding our repertoire with our new planetarium, which allows us to visualize topics in novel ways and supplements family observing on cloudy nights. The DSBK volunteers have also created a bilingual astronomy artbook --- designed, written, and illustrated by UVa students --- that we will publish and distribute to elementary schools in Virginia. Our book debuted at the last AAS winter meeting, and since then it has been extensively revised and updated with input from many individuals, including parents, professional educators, and a children's book author. Because the club is currently limited to serving a few elementary schools, this book will be part of our efforts to broaden our impact by bringing astronomy to schools we cannot go to ourselves and reaching out to Spanish-speaking communities at the same time.

2016-10-01

I am an artist, who is deeply inspired by science. Since the landing of the robotic probe Philae on the comet I have been working on an art project called 67P. Having a goal of discovering our place in the universe, I chose ESA's Rosetta mission as a successful example of such discovery. During the conference I'd like to expand the dialogue to include an artistic research of the comet 67P. I invite the participants to explore 67P through the lens of art and create inspirational reciprocity in between two spheres, creative and scientific. New ideas often originate when two vocabularies are smashed together. Via this path we perhaps will be able to get a new way of exploring the topic of cometary science.During the conference I'd like to present:- 67p artwork in the art section- poster outlining the major focuses of my projectArt project focuses:- 67P water:In the art studio I re-create water that is close in composition to the water on the comet, by enriching it with D2O. With this water I paint large scale paintings, based on the photographs by Rosetta (OSIRIS, Nav. Cam.).- spectroscopic data:Inspired by data from OSIRIS, I create an additional layer to my work using augmented reality to reveal a "hidden" from the view layer. I am making a parallel with the idea that some scientific information could be viewed only by using special instruments, in this case - instruments on board of Rosetta spacecraft, such as OSIRIS. You will be able to see a virtual layer on top of my paintings using a readily available instrument - your cellphone. Red, Green and Blue colors, of particular wavelength, will be introduced to the monochromatic paintings.- magnetometer readings:International music collaboration inspired by the "Singing comet" composition, based on the magnetometer data of 67P will be offered for any interested spectators.- 67P smell:In collaboration with The Open University, UK, postcards with a smell of the comet were created, introducing the chemical components of the comet.

2017-12-01

The complexities inherent in Arctic research demand a unique focus on making connections across the boundaries of discipline, institution, sector, geography, knowledge system, and culture. Since 1988, ARCUS has been working to bridge these gaps through communication, coordination, and collaboration. Recently, we have worked with partners to create a synthesis of the Arctic system, to explore the connectivity across the Arctic research community and how to strengthen it, to enable the community to have an effective voice in research funding policy, to implement a system for Arctic research community knowledge management, to bridge between global Sea Ice Prediction Network researchers and the science needs of coastal Alaska communities through the Sea Ice for Walrus Outlook, to strengthen ties between Polar researchers and educators, and to provide essential intangible infrastructure that enables cost-effective and productive research across boundaries. Employing expertise in managing for collaboration and interdisciplinarity, ARCUS complements and enables the work of its members, who constitute the Arctic research community and its key stakeholders. As a member-driven organization, everything that ARCUS does is achieved through partnership, with strong volunteer leadership of each activity. Key organizational partners in the United States include the U.S. Arctic Research Commission, Interagency Arctic Research Policy Committee, National Academy of Sciences Polar Research Board, and the North Slope Science Initiative. Internationally, ARCUS maintains strong bilateral connections with similarly focused groups in each Arctic country (and those interested in the Arctic), as well as with multinational organizations including the International Arctic Science Committee, the Association of Polar Early Career Educators, the University of the Arctic, and the Arctic Institute of North America. Currently, ARCUS is applying the best practices of the science of team science, expanding awareness of Arctic research in Washington, DC and in Alaska, and working to expand the base of support for Arctic research during this time of challenged U.S. federal research funding. The presentation will highlight our latest work to promote synthesis and systems thinking and make valuable connections.

Transition from single to multiple axial potential structure in expanding helicon plasma

NASA Astrophysics Data System (ADS)

Ghosh, Soumen; Chattopadhyay, P. K.; Ghosh, J.; Pal, R.; Bora, D.

2017-02-01

Transition from single to multiple axial potential structure (MAPS) formation is reported in expanding helicon plasma. This transition is created by forming a cusp magnetic field at the downstream after the expansion throat. Two distinct potential drops are separated by a uniform axial potential zone. Non-uniform axial density distribution exists in expanding helicon systems. A cusp-like field nourishes both the axial density gradients sufficient enough for the formation of these two distinct potential drops. It is also shown that both single and multiple axial potential structures are observed only when both geometric and magnetic expansions closely coincide with each other. Coexistence of these two expansions at the same location enhances plasma expansion which facilitates deviation from Boltzmann distribution and violates quasi-neutrality locally.

The interaction of high-velocity plasma flows in a background magnetic field has applications in pulsed-power and fusion schemes, as well as astrophysical environments, such as accretion systems and stellar mass ejections into the magnetosphere. Experiments recently executed at the Trident Laser Facility at the Los Alamos National Laboratory investigated the effects of an expanding aluminum plasma flow into a uniform 4.5-Tesla magnetic field created using a solenoid designed and manufactured at the University of Michigan. Opposing-target experiments demonstrate interesting collisional behavior between the two magnetized flows. Preliminary interferometry and Faraday rotation measurements will be presented and discussed. This work is funded by the U.S Department of Energy, through the NNSA-DS and SC-OFES Joint Program in High-Energy-Density Laboratory Plasmas, grant number DE-NA0001840. Support for this work was provided by NASA through Einstein Postdoctoral Fellowship grant number PF3-140111 awarded by the Chandra X-ray Center, which is operated by the Astrophysical Observatory for NASA under contract NAS8-03060.

Transforming exoelectrogens for biotechnology using synthetic biology.

PubMed

TerAvest, Michaela A; Ajo-Franklin, Caroline M

2016-04-01

Extracellular electron transfer pathways allow certain bacteria to transfer energy between intracellular chemical energy stores and extracellular solids through redox reactions. Microorganisms containing these pathways, exoelectrogens, are a critical part of microbial electrochemical technologies that aim to impact applications in bioenergy, biosensing, and biocomputing. However, there are not yet any examples of economically viable microbial electrochemical technologies due to the limitations of naturally occurring exoelectrogens. Here we first briefly summarize recent discoveries in understanding extracellular electron transfer pathways, then review in-depth the creation of customized and novel exoelectrogens for biotechnological applications. We analyze engineering efforts to increase current production in native exoelectrogens, which reveals that modulating certain processes within extracellular electron transfer are more effective than others. We also review efforts to create new exoelectrogens and highlight common challenges in this work. Lastly, we summarize work utilizing engineered exoelectrogens for biotechnological applications and the key obstacles to their future development. Fueled by the development of genetic tools, these approaches will continue to expand and genetically modified organisms will continue to improve the outlook for microbial electrochemical technologies. © 2015 Wiley Periodicals, Inc.

Comprehensive study of the abrasive wear and slurry erosion behavior of an expanded system of high chromium cast iron and microstructural modification for enhanced wear resistance

NASA Astrophysics Data System (ADS)

Chung, Reinaldo Javier

High chromium cast irons (HCCIs) have been demonstrated to be an effective material for a wide range of applications in aggressive environments, where resistances to abrasion, erosion and erosion-corrosion are required. For instance, machinery and facilities used in mining and extraction in Alberta's oil sands suffer from erosion and erosion-corrosion caused by silica-containing slurries, which create challenges for the reliability and maintenance of slurry pumping systems as well as other processing and handling equipment. Considerable efforts have been made to determine and understand the relationship between microstructural features of the HCCIs and their wear performance, in order to guide the material selection and development for specific service conditions with optimal performance. The focus was previously put on a narrow group of compositions dictated by ASTM A532. However, with recent advances in casting technology, the HCCI compositional range can be significantly expanded, which potentially brings new alloys that can be superior to those which are currently employed. This work consists of three main aspects of study. The first one is the investigation of an expanded system of white irons with their composition ranging from 1 to 6 wt.% C and 5 to 45 wt.% Cr, covering 53 alloys. This work has generated wear and corrosion maps and established correlation between the performance and microstructural features for the alloys. The work was conducted in collaboration with the Materials Development Center of Weir Minerals in Australia, and the results have been collected in a database that is used by the company to guide materials selection for slurry pump components in Alberta oil sands and in other mining operations throughout the world. The second part consists of three case studies on effects of high chromium and high carbon, respectively, on the performance of the HCCIs. The third aspect is the development of an approach to enhance the wear resistance of HCCIs by microstructural modification through addition of strong carbide-forming elements to produce eutectic microstructures reinforced with in-situ formed foreign carbides. Very promising results have been obtained in lab, which demonstrates that the approach is feasible and effective in tailoring HCCIs for improved performance.

Creating a Connected Community: Lessons Learned from the Western New York Beacon Community

PubMed Central

Maloney, Nancy; Heider, Arvela R.; Rockwood, Amy; Singh, Ranjit

2014-01-01

Introduction: Secure exchange of clinical data among providers has the potential to improve quality, safety, efficiency, and reduce duplication. Many communities are experiencing challenges in building effective health information exchanges (HIEs). Previous studies have focused on financial and technical issues regarding HIE development. This paper describes the Western New York (WNY) HIE growth and lessons learned about accelerating progress to become a highly connected community. Methods: HEALTHeLINK, with funding from the Office of the National Coordinator for Health Information Technology (ONC) under the Beacon Community Program, expanded HIE usage in eight counties. The communitywide transformation process used three main drivers: (1) a communitywide Electronic Health Record (EHR) adoption program; (2) clinical transformation partners; and (3) HIE outreach and infrastructure development. Results: ONC Beacon Community funding allowed WNY to achieve a new level in the use of interoperable HIE. Electronic delivery of results into the EHR expanded from 23 practices in 2010 to 222 practices in 2013, a tenfold increase. There were more than 12.5 million results delivered electronically (HL7 messages) to 222 practices’ EHRs via the HIE in 2013. Use of a secure portal and Virtual Health Record (VHR) to access reports (those not delivered directly to the EHR) also increased significantly, from 13,344 report views in 2010 to over 600,000 in 2013. Discussion and Conclusion: The WNY Beacon successfully expanded the sharing of clinical information among different sources of data and providers, creating a highly connected community to improve the quality and continuity of care. Technical, organizational, and community lessons described in this paper should prove beneficial to others as they pursue efforts to create connected communities. PMID:25848618

2011-01-01

Question: How can library staff develop and promote a document delivery service and then expand the service to a wide audience? Setting: The setting is the library at the Indiana University School of Dentistry (IUSD), Indianapolis. Method: A faculty survey and a citation analysis were conducted to determine potential use of the service. Volume of interlibrary loan transactions and staff and equipment capacity were also studied. Main results: IUSD Library staff created a desktop delivery service (DDSXpress) for faculty and then expanded the service to practicing dental professionals and graduate students. The number of faculty using DDSXpress remains consistent. The number of practicing dental professionals using the service is low. Graduate students have been quick to adopt the service. Conclusion: Through careful analysis of capacity and need for the service, staff successfully expanded document delivery service without incurring additional costs. Use of DDSXpress is continually monitored, and opportunities to market the service to practicing dental professionals are being investigated. PMID:21753911

Short paths in expander graphs

DOE Office of Scientific and Technical Information (OSTI.GOV)

Kleinberg, J.; Rubinfeld, R.

Graph expansion has proved to be a powerful general tool for analyzing the behavior of routing algorithms and the interconnection networks on which they run. We develop new routing algorithms and structural results for bounded-degree expander graphs. Our results are unified by the fact that they are all based upon, and extend, a body of work asserting that expanders are rich in short, disjoint paths. In particular, our work has consequences for the disjoint paths problem, multicommodify flow, and graph minor containment. We show: (i) A greedy algorithm for approximating the maximum disjoint paths problem achieves a polylogarithmic approximation ratiomore » in bounded-degree expanders. Although our algorithm is both deterministic and on-line, its performance guarantee is an improvement over previous bounds in expanders. (ii) For a multicommodily flow problem with arbitrary demands on a bounded-degree expander, there is a (1 + {epsilon})-optimal solution using only flow paths of polylogarithmic length. It follows that the multicommodity flow algorithm of Awerbuch and Leighton runs in nearly linear time per commodity in expanders. Our analysis is based on establishing the following: given edge weights on an expander G, one can increase some of the weights very slightly so the resulting shortest-path metric is smooth - the min-weight path between any pair of nodes uses a polylogarithmic number of edges. (iii) Every bounded-degree expander on n nodes contains every graph with O(n/log{sup O(1)} n) nodes and edges as a minor.« less

PIC Simulations of Hypersonic Plasma Instabilities

NASA Astrophysics Data System (ADS)

Niehoff, D.; Ashour-Abdalla, M.; Niemann, C.; Decyk, V.; Schriver, D.; Clark, E.

2013-12-01

The plasma sheaths formed around hypersonic aircraft (Mach number, M > 10) are relatively unexplored and of interest today to both further the development of new technologies and solve long-standing engineering problems. Both laboratory experiments and analytical/numerical modeling are required to advance the understanding of these systems; it is advantageous to perform these tasks in tandem. There has already been some work done to study these plasmas by experiments that create a rapidly expanding plasma through ablation of a target with a laser. In combination with a preformed magnetic field, this configuration leads to a magnetic "bubble" formed behind the front as particles travel at about Mach 30 away from the target. Furthermore, the experiment was able to show the generation of fast electrons which could be due to instabilities on electron scales. To explore this, future experiments will have more accurate diagnostics capable of observing time- and length-scales below typical ion scales, but simulations are a useful tool to explore these plasma conditions theoretically. Particle in Cell (PIC) simulations are necessary when phenomena are expected to be observed at these scales, and also have the advantage of being fully kinetic with no fluid approximations. However, if the scales of the problem are not significantly below the ion scales, then the initialization of the PIC simulation must be very carefully engineered to avoid unnecessary computation and to select the minimum window where structures of interest can be studied. One method of doing this is to seed the simulation with either experiment or ion-scale simulation results. Previous experiments suggest that a useful configuration for studying hypersonic plasma configurations is a ring of particles rapidly expanding transverse to an external magnetic field, which has been simulated on the ion scale with an ion-hybrid code. This suggests that the PIC simulation should have an equivalent configuration; however, modeling a plasma expanding radially in every direction is computationally expensive. In order to reduce the computational expense, we use a radial density profile from the hybrid simulation results to seed a self-consistent PIC simulation in one direction (x), while creating a current in the direction (y) transverse to both the drift velocity and the magnetic field (z) to create the magnetic bubble observed in experiment. The simulation will be run in two spatial dimensions but retain three velocity dimensions, and the results will be used to explore the growth of micro-instabilities present in hypersonic plasmas in the high-density region as it moves through the simulation box. This will still require a significantly large box in order to compare with experiment, as the experiments are being performed over distances of 104 λDe and durations of 105 ωpe-1.

Magma Fragmentation

NASA Astrophysics Data System (ADS)

Gonnermann, Helge M.

2015-05-01

Magma fragmentation is the breakup of a continuous volume of molten rock into discrete pieces, called pyroclasts. Because magma contains bubbles of compressible magmatic volatiles, decompression of low-viscosity magma leads to rapid expansion. The magma is torn into fragments, as it is stretched into hydrodynamically unstable sheets and filaments. If the magma is highly viscous, resistance to bubble growth will instead lead to excess gas pressure and the magma will deform viscoelastically by fracturing like a glassy solid, resulting in the formation of a violently expanding gas-pyroclast mixture. In either case, fragmentation represents the conversion of potential energy into the surface energy of the newly created fragments and the kinetic energy of the expanding gas-pyroclast mixture. If magma comes into contact with external water, the conversion of thermal energy will vaporize water and quench magma at the melt-water interface, thus creating dynamic stresses that cause fragmentation and the release of kinetic energy. Lastly, shear deformation of highly viscous magma may cause brittle fractures and release seismic energy.

To evaluate the effectiveness of a new vascular occlusion device. The device was created by coating a balloon-expandable stent with a silicone sleeve that tapers to a blind-ended nozzle at its leading end. Once crimp-mounted on an angioplasty balloon catheter, the device is introduced over a guide wire through a small end hole in the nozzle. The device was tested for stability and occlusive ability. No migration was measured over a pulsatile pulse range of 50-300 mm Hg, and mean flow rate in the occluded vessel was reduced from 443 mL/min +/- 99 (standard deviation) to 1.9 mL/min +/- 2.7. Subsequently, 12 arteries were occluded in three dogs, and immediate vascular occlusion was achieved in all vessels. An arteriovenous fistula was created in another six dogs and was successfully occluded with the device. Follow-up arteriography at 3 months demonstrated persistent occlusion with no migration of the device. This new occlusive device offers immediate vascular occlusion with excellent stability.

Creation and Evolution of Particle Number Asymmetry in an Expanding Universe

2017-03-01

We introduce a model which may generate particle number asymmetry in an expanding Universe. The model includes charge parity (CP) violating and particle number violating interactions. The model consists of a real scalar field and a complex scalar field. Starting with an initial condition specified by a density matrix, we show how the asymmetry is created through the interaction and how it evolves at later time. We compute the asymmetry using non-equilibrium quantum field theory and as a first test of the model, we study how the asymmetry evolves in the flat limit.

The design briefing process matters: a case study on telehealthcare device providers in the UK.

The telehealthcare sector has been expanding steadily in the UK. However, confusing, complex and unwieldy designs of telehealthcare devices are at best, less effective than they could be, at worst, they are potentially dangerous to the users. This study investigated the factors within the new product development process that hindered satisfactory product design outcomes, through working collaboratively with a leading provider based in the UK. This study identified that there are too many costly late-stage design changes; a critical and persistent problem area ripe for improvement. The findings from analyzing 30 recent devices, interviewing key stakeholders and observing on-going projects further revealed that one major cause of the issue was poor practice in defining and communicating the product design criteria and requirements. Addressing the characteristics of the telehealthcare industry, such as multiple design commissioners and frequent deployment of design subcontracts, this paper argues that undertaking a robust process of creating the product design brief is the key to improving the outcomes of telehealthcare device design, particularly for the small and medium-sized enterprises dominating the sector. Implications for rehabilitation Product design criteria and requirements are frequently ill-defined and ineffectively communicated to the designers within the processes of developing new telehealthcare devices. The absence of a (robust) process of creating the design brief is the root cause of the identified issues in defining and communicating the design task. Deploying a formal process of creating the product design brief is particularly important for the telehealthcare sector.

As the field of behavior analysis expands internationally, the need for comprehensive and systematic glossaries of behavioral terms in the vernacular languages of professionals and clients becomes crucial. We created a Spanish-language glossary of behavior-analytic terms by developing and employing a systematic set of decision-making rules for the inclusion of terms. We then submitted the preliminary translation to a multi-national advisory committee to evaluate the transnational acceptability of the glossary. This method led to a translated corpus of over 1200 behavioral terms. The end products of this work included the following: (a) a Spanish-language glossary of behavior analytic terms that are publicly available over the Internet through the Behavior Analyst Certification Board and (b) a set of translation guidelines summarized here that may be useful for the development of glossaries of behavioral terms into other vernacular languages.

Radiant thinking and the use of the mind map in nurse practitioner education.

The concept of radiant thinking, which led to the concept of mind mapping, promotes all aspects of the brain working in synergy, with thought beginning from a central point. The mind map, which is a graphical technique to improve creative thinking and knowledge attainment, utilizes colors, images, codes, and dimensions to amplify and enhance key ideas. This technique augments the visualization of relationships and links between concepts, which aids in information acquisition, data retention, and overall comprehension. Faculty can promote students' use of the technique for brainstorming, organizing ideas, taking notes, learning collaboratively, presenting, and studying. These applications can be used in problem-based learning, developing plans of care, health promotion activities, synthesizing disease processes, and forming differential diagnoses. Mind mapping is a creative way for students to engage in a unique method of learning that can expand memory recall and help create a new environment for processing information.

Plasma Heating: An Advanced Technology

NASA Technical Reports Server (NTRS)

1994-01-01

The Mercury and Apollo spacecraft shields were designed to protect astronauts from high friction temperatures (well over 2,000 degrees Fahrenheit) when re-entering the Earth's atmosphere. It was necessary to test and verify the heat shield materials on Earth before space flight. After exhaustive research and testing, NASA decided to use plasma heating as a heat source. This technique involves passing a strong electric current through a rarefied gas to create a plasma (ionized gas) that produces an intensely hot flame. Although NASA did not invent the concept, its work expanded the market for commercial plasma heating systems. One company, Plasma Technology Corporation (PTC), was founded by a member of the team that developed the Re-entry Heating Simulator at Ames Research Center (ARC). Dr. Camacho, President of PTC, believes the technology has significant environmental applications. These include toxic waste disposal, hydrocarbon, decomposition, medical waste disposal, asbestos waste destruction, and chemical and radioactive waste disposal.

In changing higher education environments, health profession's educators have been increasingly challenged to prepare future health professionals to care for aging populations. This article reports on an exploratory, mixed-method research study that used an innovative photo-elicitation technique and interprofessional small-group work in the classroom to enhance the reflective learning experience of medical and nursing students. Data were collected from pre- and postquestionnaires and focus groups to explore shifts in perceptions toward older persons following the reflective learning session. The qualitative data revealed how using visual images of older persons provides a valuable learning space for reflection. Students found meaning in their own learning by creating shared storylines that challenged their perceptions of older people and themselves as future health professionals. These data support the use of visual methodologies to enhance engagement, reflection, and challenge students to explore and deepen their understanding in gerontology.

Rethinking Skin Lesion Segmentation in a Convolutional Classifier.

Melanoma is a fatal form of skin cancer when left undiagnosed. Computer-aided diagnosis systems powered by convolutional neural networks (CNNs) can improve diagnostic accuracy and save lives. CNNs have been successfully used in both skin lesion segmentation and classification. For reasons heretofore unclear, previous works have found image segmentation to be, conflictingly, both detrimental and beneficial to skin lesion classification. We investigate the effect of expanding the segmentation border to include pixels surrounding the target lesion. Ostensibly, segmenting a target skin lesion will remove inessential information, non-lesion skin, and artifacts to aid in classification. Our results indicate that segmentation border enlargement produces, to a certain degree, better results across all metrics of interest when using a convolutional based classifier built using the transfer learning paradigm. Consequently, preprocessing methods which produce borders larger than the actual lesion can potentially improve classifier performance, more than both perfect segmentation, using dermatologist created ground truth masks, and no segmentation altogether.

The emotionally competent leader.

Aristotle once challenged man "to be angry with the right person, to the right degree, at the right time, for the right purpose, and in the right way" (The Nicomachean Ethics). Daniel Goleman, Ph.D., a journalist for the New York Times, expands on this statement in his new book, "Emotional Intelligence." He defines emotional intelligence as the ability to rein in emotional impulses, to read another's innermost feelings and to handle relationships and conflict smoothly. This new model of intelligence puts emotions at the center of our aptitudes for living. Goleman asserts that these emotional aptitudes can preserve relationships, protect our health and improve our success at work. The following adaptation from "Emotional Intelligence" (Bantam Books, 1995) offers suggestions to managers and supervisors on how they can create a more cost-effective and healthier workplace for their employees by becoming more aware of their own emotional. intelligence.

The growing burden of Alzheimer’s disease underscores the importance of enhancing current public health efforts to address dementia. Public health organizations and entities have substantial opportunities to contribute to efforts underway and to add innovations to the field. The Alzheimer’s Association and the Centers for Disease Control and Prevention worked with a 15-member leadership committee and hundreds of stakeholders to create The Healthy Brain Initiative: The Public Health Road Map for State and National Partnerships, 2013–2018 (Road Map). The actions in the Road Map provide a foundation for the public health community to anticipate and respond to emerging innovations and developments. It will be a challenge to harness the increasingly complex nature of public- and private-sector collaborations. We must strengthen the capacity of public health agencies, leverage partnerships, and find new ways to integrate cognitive functioning into public health efforts. PMID:25088658

Pushing the boundaries of cultural congruence pedagogy in science education towards a third space

This review explores Meyers and Crawford's "Teaching science as a cultural way of knowing: Merging authentic inquiry, nature of science, and multicultural strategies" by examining how they combine the use of inquiry-based science instruction with multicultural strategies. In this conversation, I point to the need of specific discourse strategies to help teachers and students create hybrid spaces to push the boundaries of cultural congruence as described in this article. These strategies include a reflective component to the explicit instruction that encourages an integration of home and science discourses. My response to this work expands on their use of multicultural strategies to push toward a congruent Third space that asks not only what happens to the students who do not participate in science, but also what happens to science when a diverse group of people does not participate?

The authors report results of work to enhance self-report posttraumatic stress disorder (PTSD) assessment by developing an item bank for use in a computer-adapted test. Computer-adapted tests have great potential to decrease the burden of PTSD assessment and outcomes monitoring. The authors conducted a systematic literature review of PTSD instruments, created a database of items, performed qualitative review and readability analysis, and conducted cognitive interviews with veterans diagnosed with PTSD. The systematic review yielded 480 studies in which 41 PTSD instruments comprising 993 items met inclusion criteria. The final PTSD item bank includes 104 items representing each of the Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition (DSM-IV; American Psychiatric Association [APA], 1994), PTSD symptom clusters (reexperiencing, avoidance, and hyperarousal), and 3 additional subdomains (depersonalization, guilt, and sexual problems) that expanded the assessment item pool.

Engineers at Marshall Space Flight Center (MSFC) in Huntsville, Alabama, are working with industry partners to develop a new generation of more cost-efficient space vehicles. Lightweight fuel tanks and components under development will be the critical elements in tomorrow's reusable launch vehicles and will tremendously curb the costs of getting to space. In this photo, Tom DeLay, a materials processes engineer for MSFC, uses a new graphite epoxy technology to create lightweight cryogenic fuel lines for futuristic reusable launch vehicles. He is wrapping a water-soluble mandrel, or mold, with a graphite fabric coated with an epoxy resin. Once wrapped, the pipe will be vacuum-bagged and autoclave-cured. The disposable mold will be removed to reveal a thin-walled fuel line. In addition to being much lighter and stronger than metal, this material won't expand or contract as much in the extreme temperatures encountered by launch vehicles.

The 4th annual European League Against Rheumatism congress, held in Lisbon, 18–21 June 2003, had a record turnout of more than 8600 delegates and the abstract submissions increased to 2600. A heat wave and a somewhat substandard venue hampered some of the activities, notably the poster sessions. The scientific program was comprehensive and of a high class, and it was organized in 10–12 parallel sessions. The European League Against Rheumatism standing committees are expanding their activities and stimulating European cooperation (e.g. by creating databases and guidelines, and by starting research programs). The standing committees presented several areas where European cooperative work is in progress. Advances in drug therapy were a prominent theme and were well presented. Commercialism remains a problem for this meeting as for other similar large meetings, where satellite symposia surround the scientific program of the congress and often duplicate this. PMID:14979931

Simple and predictable trans-acting regulatory tools are needed in the fields of synthetic biology and metabolic engineering to build complex genetic circuits and optimize the levels of native and heterologous gene products. Transcription activator-like effectors (TALEs) are bacterial virulence factors that have recently gained traction in biotechnology applications owing to their customizable DNA-binding specificity. In this work we expanded the versatility of these transcription factors to create an inducible TALE system by inserting tobacco-etch virus (TEV) protease recognition sites into the TALE backbone. The resulting engineered TALEs maintain transcriptional repression of their target genes in Escherichia coli, but are degraded after induction of the TEV protease, thereby promoting expression of the previously repressed target gene of interest. This TALE-TEV technology enables both repression and induction of plasmid or chromosomal target genes in a manner analogous to traditional repressor proteins but with the added flexibility of being operator-agnostic.

Molecular spins have become key enablers for exploring magnetic interactions, quantum information processes and many-body effects in metals. Metal-organic molecules, in particular, let the spin state of the core metal ion to be modified according to its organic environment, allowing localized magnetic moments to emerge as functional entities with radically different properties from its simple atomic counterparts. Here, using and preserving the integrity of transition metal phthalocyanine high-spin complexes, we demonstrate the magnetic doping of gold thin films, effectively creating a new ground state. We demonstrate it by electrical transport measurements that are sensitive to the scattering of itinerant electrons with magnetic impurities, such as Kondo effect and weak antilocalization. Our work expands in a simple and powerful way the classes of materials that can be used as magnetic dopants, opening a new channel to couple the wide range of molecular properties with spin phenomena at a functional scale.

Therefore patient input, which is increasingly important in weighing benefits and risks, is particularly relevant for this class of devices. FDA has been a significant contributor to an ongoing stakeholder conversation about the inclusion of the patient voice, working collaboratively to create a new framework for a patient-centered approach to medical device development. This framework is evolving through open dialogue with researcher and patient communities, investment in the science of patient input, and policymaking that is responsive to patient-centered data throughout the total product life cycle.

Interprofessional education (IPE) is increasingly called upon to improve health care systems and patient safety. Our institution is engaged in a campus-wide IPE initiative. As a component of this initiative, a required online interprofessional patient-safety-focused course for a large group (300) of first-year medical, dental, and nursing students was developed and implemented. We describe our efforts with developing the course, including the use of constructivist and adult learning theories and IPE competencies to structure students' learning in a meaningful fashion. The course was conducted online to address obstacles of academic calendars and provide flexibility for faculty participation. Students worked in small groups online with a faculty facilitator. Thematic modules were created with associated objectives, online learning materials, and assignments. Students posted completed assignments online and responded to group members' assignments for purposes of group discussion. Students worked in interprofessional groups on a project requiring them to complete a root cause analysis and develop recommendations based on a fictional sentinel event case. Through project work, students applied concepts learned in the course related to improving patient safety and demonstrated interprofessional collaboration skills. Projects were presented during a final in-class session. Student course evaluation results suggest that learning objectives and content goals were achieved. Faculty course evaluation results indicate that the course was perceived to be a worthwhile learning experience for students. We offer the following recommendations to others interested in developing an in-depth interprofessional learning experience for a large group of learners: 1) consider a hybrid format (inclusion of some face-to-face sessions), 2) address IPE and broader curricular needs, 3) create interactive opportunities for shared learning and working together, 4) provide support to faculty facilitators, and 5) recognize your learners' educational level. The course has expanded to include students from additional programs for the current academic year.

Designing a Virtual Research Facility to motivate Professional-Citizen Collaboration

NASA Astrophysics Data System (ADS)

Gay, Pamela

In order to handle the onslaught of data spilling from telescopes on the Earth and on orbit, CosmoQuest has created a virtual research facility that allows the public to collaborate with science teams on projects that would otherwise lack the necessary human resources. This second-generation citizen science site goes beyond asking people to click on images to also engaging them in taking classes, attending virtual seminars, and participating in virtual star parties. These features were introduced to try and expand the diversity of motivations that bring people to the project and to keep them engaged overtime - just as a research center seeks to bring a diversity of people together to work and learn over time. In creating the CosmoQuest Virtual Research Facility, we sought to answer the question, “What would happen if we provided the public with the same kinds of facilities scientists have, and invite them to be our collaborators?” It had already been observed that the public readily attends public science lectures, open houses at science facilities, and education programs such as star parties. It was hoped that by creating a central facility, we could build a community of people learning and doing science in a productive manner. In order to be successful, we needed to first create the facility, then test if people were coming both to learn and to do science, and finally to verify that people were doing legitimate science. During the past 18 months of operations, we have continued to work through each of these stages, as discussed talk. At this early date, progress is on-going, and much research remains to be done, but all indications show that we are on our way to building a community of people learning and doing science. During 2013-2014, a series of studies looked at the motivations of CosmoQuest users, as well as their forms of site interactions. During this talk, we will review these results, as well as the demographics of our user population.

The Surface Ocean CO2 Atlas: Stewarding Underway Carbon Data from Collection to Archival

The Surface Ocean CO2 Atlas (SOCAT, www.socat.info) is a quality controlled, global surface ocean carbon dioxide (CO2) data set gathered on research vessels, SOOP and buoys. To the degree feasible SOCAT is comprehensive; it draws together and applies uniform QC procedures to all such observations made across the international community. The first version of SOCAT (version 1.5) was publicly released September 2011(Bakker et al., 2011) with 6.3 million observations. This was followed by the release of SOCAT version 2, expanded to over 10 million observations, in June 2013 (Bakker et al., 2013). Most recently, in September 2015 SOCAT version 3 was released containing over 14 millions observations spanning almost 60 years! The process of assembling, QC'ing and publishing V1.5 and V2 of SOCAT required an unsustainable level of manual effort. To ease the burden on data managers and data providers, the SOCAT community agreed to embark an automated data ingestion process which would create a streamlined workflow to improve data stewardship from ingestion to quality control and from publishing to archival. To that end, for version 3 and beyond, the SOCAT automation team created a framework which was based upon standards and conventions, yet at the same time allows scientists to work in the data formats they felt most comfortable with (ie, csv files). This automated workflow provides several advantages: 1) data ingestion into uniform and standards-based file formats; 2) ease of data integration into standard quality control system; 3) data ingestion and quality control can be performed in parallel; 4) provides uniform method of archiving carbon data and generation of digital object identifiers (DOI).In this presentation, we will discuss and demonstrate the SOCAT data ingestion dashboard and the quality control system. We will also discuss the standards, conventions, and tools that were leveraged to create a workflow that allows scientists to work in their own formats, yet provides a framework for creating high quality data products on an annual basis, while meeting or exceeding data requirements for access, documentation and archival.

Letter: Entrapment and interaction of an air bubble with an oscillating cavitation bubble

NASA Astrophysics Data System (ADS)

Kannan, Y. S.; Karri, Badarinath; Sahu, Kirti Chandra

2018-04-01

The mechanism of the formation of an air bubble due to an oscillating cavitation bubble in its vicinity is reported from an experimental study using high-speed imaging. The cavitation bubble is created close to the free surface of water using a low-voltage spark circuit comprising two copper electrodes in contact with each other. Before the bubble is created, a third copper wire is positioned in contact with the free surface of water close to the two crossing electrodes. Due to the surface tension at the triple point (wire-water-air) interface, a small dip is observed in the free surface at the point where the wire is immersed. When the cavitation bubble is created, the bubble pushes at the dip while expanding and pulls at it while collapsing. The collapse phase leads to the entrapment of an air bubble at the wire immersion point. During this phase, the air bubble undergoes a "catapult" effect, i.e., it expands to a maximum size and then collapses with a microjet at the free surface. To the best of our knowledge, this mechanism has not been reported so far. A parametric study is also conducted to understand the effects of wire orientation and bubble distance from the free surface.

Creating a More Diverse Midwifery Workforce in the United States: A Historical Reflection.

PubMed

Dawley, Katy; Walsh, Linda V

2016-09-01

As nurse-midwifery practice expanded beyond areas surrounding early nurse-midwifery education programs, leaders in the profession wanted to establish a strong diverse, inclusive professional organization, a necessary step in creating a diverse workforce (defined here as open to nurse-midwives of all colors, ethnicities, and national origins) that would maintain standards, provide continuing education, and facilitate communication among nurse-midwives. This research presents historical context and organizational factors supporting and limiting development of a workforce reflective of communities served by nurse-midwives. Searches in the National Library of Medicine Historical Collection, American College of Nurse-Midwives (ACNM) Collections, and the Rockefeller Archives Center, as well as recorded interview data, provided primary sources for analysis. Secondary sources include research and opinions in scholarly publications including journals and books released from 1930 to the present. Nurse-midwifery leaders developed relationships with well-respected philanthropists, as well as maternal and child health administrators in state departments of health and the US Children's Bureau, to implement initiatives to recruit and retain midwives of color. Continued interest in the goal of inclusion, work of midwives of color, and commitment to creating a diverse workforce led to the creation of the standing ACNM Midwives of Color Committee in 1990 and the Diversity and Inclusion Task Force, which released its report, "Shifting the Frame: A Report on Diversity and Inclusion in the American College of Nurse-Midwives," 1 in June 2015. Over the past 60 years, ACNM leadership and midwives of color have continued to explore new and effective means to create a workforce that reflects the communities in which nurse-midwives practice. © 2016 by the American College of Nurse-Midwives.

Standardization of electronic medical record, so as to enable resource-sharing and information exchange among medical institutions has become inevitable in view of the ever increasing medical information. The current research is an effort towards the standardization of basic dataset of electronic medical records in traditional Chinese medicine. In this work, an outpatient clinical information model and an inpatient clinical information model are created to adequately depict the diagnosis processes and treatment procedures of traditional Chinese medicine. To be backward compatible with the existing dataset standard created for western medicine, the new standard shall be a superset of the existing standard. Thus, the two models are checked against the existing standard in conjunction with 170,000 medical record cases. If a case cannot be covered by the existing standard due to the particularity of Chinese medicine, then either an existing data element is expanded with some Chinese medicine contents or a new data element is created. Some dataset subsets are also created to group and record Chinese medicine special diagnoses and treatments such as acupuncture. The outcome of this research is a proposal of standardized traditional Chinese medicine medical records datasets. The proposal has been verified successfully in three medical institutions with hundreds of thousands of medical records. A new dataset standard for traditional Chinese medicine is proposed in this paper. The proposed standard, covering traditional Chinese medicine as well as western medicine, is expected to be soon approved by the authority. A widespread adoption of this proposal will enable traditional Chinese medicine hospitals and institutions to easily exchange information and share resources. Copyright © 2017.

Vian, Taryn; Richards, Sarah C; McCoy, Kelly; Connelly, Patrick; Feeley, Frank

2007-01-01

Background The ability of health organizations in developing countries to expand access to quality services depends in large part on organizational and human capacity. Capacity building includes professional development of staff, as well as efforts to create working environments conducive to high levels of performance. The current study evaluated an approach to public-private partnership where corporate volunteers give technical assistance to improve organizational and staff performance. From 2003 to 2005, the Pfizer Global Health Fellows program sent 72 employees to work with organizations in 19 countries. This evaluation was designed to assess program impact. Methods The researchers administered a survey to 60 Fellows and 48 Pfizer Supervisors. In addition, the team conducted over 100 interviews with partner organization staff and other key informants during site visits in Uganda, Kenya, Ghana, South Africa and India, the five countries where 60% of Fellows were placed. Results Over three-quarters of Fellowships appear to have imparted skills or enhanced operations of NGOs in HIV/AIDS and other health programs. Overall, 79% of Fellows reported meeting all or most technical assistance goals. Partner organization staff reported that the Fellows provided training to clinical and research personnel; strengthened laboratory, pharmacy, financial control, and human resource management systems; and helped expand Partner organization networks. Local staff also reported the Program changed their work habits and attitudes. The evaluation identified problems in defining goals of Fellowships and matching Organizations with Fellows. Capacity building success also appears related to size and sophistication of partner organization. Conclusion Public expectations have grown regarding the role corporations should play in improving health systems in developing countries. Corporate philanthropy programs based on "donations" of personnel can help build the organizational and human capacity of frontline agencies delivering health services. More attention is needed to measure and compare outcomes of international volunteering programs, and to identify appropriate strategies for expansion. PMID:17335578

Comparison of expandable endotracheal stents in the treatment of surgically induced piglet tracheomalacia.

PubMed

Mair, E A; Parsons, D S; Lally, K P; Van Dellen, A F

1991-09-01

Present surgical alternatives for pediatric tracheobronchomalacia are limited and associated with many potentially undesirable complications. The feasibility of different intraluminal expandable endotracheal stents for the treatment of surgically induced tracheomalacia was analyzed in 27 piglets. A potentially fatal tracheomalacia was surgically created. Either a stainless steel "zig-zag" stent or a woven polymeric stent was then implanted. Tracheal patency, mucosal function, histopathologic respiratory tract changes, and effects of the stent on esophageal motility were evaluated over a 16-week period. Piglets with steel stents uniformly experienced intense inflammation leading to tracheal dysfunction and death. Piglets with polymeric stents experienced minimal respiratory symptoms. Expandable polymeric endotracheal stents alleviate surgically induced piglet tracheomalacia, were easy to insert, allowed for tracheal growth, and reduced the need for high-risk surgical procedures with prolonged ventilatory support.

Increase of rotation angle of soil layers during plow operation

Vasilenko, VV; Afonichev, D. N.; Vasilenko, S. V.; Khakhulin, A. N.

2018-03-01

One of the advantages of plowing is the ability of the plow to hide the weed seeds deep into the soil. The depth of the embankment exceeds 10-12 cm, from there the weeds can not rise to the surface of the soil. They perish halfway. But for this, it is necessary to wrap the soil layers at an angle close to 180 °. Modern ploughs can not turn the layers of soil at an angle of more than 135 °, therefore the plow is required to be equipped with additional working elements. The aim of the study is to create an adaptation to the plow to expand the furrow before laying the next soil layer. In a wide furrow, the formation will completely tip, the previous layer will not interfere with it. The device is a set of vertical shields. Each shield is fixed behind the working body of the plow. It is installed with an angle of attack of 20-25 ° to move the previous layer to expand the furrow by 10-12 cm. The model and industrial samples of the plow have shown improved agrotechnical indicators. The average angle of the formation rotation was 177 °, the burial of plant residues in the soil increased from 61 to 99%. The field surface with blocks more than 5 cm decreased from 36.3 to 13.4%, the height of the ridges decreased from 7 to 4 cm. The force of soil pressure on the shield was measured by a strain gage. It is 130-330 N depending on the depth of processing and the speed of movement. The increase in power costs for the four-hull plow was 190-750 W. The coulters on the plow are unnecessary, and this saves energy more than its increase for shields.

Global trade, local impacts: lessons from California on health impacts and environmental justice concerns for residents living near freight rail yards.

Global trade has increased nearly 100-fold since 1950, according to the World Trade Organization. Today, major changes in trade are occurring with the advent of mega-ships that can transport thousands more containers than cargo ships now in use. Because global trade is expected to increase dramatically, the railroad industry-in the U.S. alone-has invested more than $5 billion a year over the past decade to expand rail yards and enhance rail routes to transport goods from ports to retail destinations. This article describes cancer risks for residents living in close proximity to rail yards with emissions of diesel particulate matter pollution from locomotives, trucks and yard equipment. The article examines the demographics (income, race/ethnicity) of populations living in the highest estimated cancer risk zones near 18 major rail yards in California, concluding that the majority are over-represented by either lower-income or minority residents (or both). The authors also describe a review of the news media and environmental impact reports to determine if rail yards are still being constructed or expanded in close proximity to homes and schools or in working class/working poor communities of color. The paper suggests policy efforts that might provide more public health protection and result in more "environmentally just" siting of rail yards. The authors conclude that diesel pollution from rail yards, which creates significant diesel cancer risks for those living near the facilities, is an often overlooked public health, health disparities and environmental justice issue in the U.S. The conclusions are relevant to other countries where international trade is increasing and large new intermodal rail facilities are being considered.

State geoscientists (geologists, geophysicists, seismologists, and engineers) in California work closely with federal, state and local government emergency managers to help prepare coastal communities for potential impacts from a tsunami before, during, and after an event. For teletsunamis, as scientific information (forecast model wave heights, first-wave arrival times, etc.) from NOAA's West Coast and Alaska Tsunami Warning Center is made available, federal- and state-level emergency managers must help convey this information in a concise, comprehensible and timely manner to local officials who ultimately determine the appropriate response activities for their jurisdictions. During the September 29, 2009 Tsunami Advisory for California, government geoscientists assisted the California Emergency Management Agency by providing technical assistance during teleconference meetings with NOAA and other state and local emergency managers prior to the arrival of the tsunami. This technical assistance included background information on anticipated tidal conditions when the tsunami was set to arrive, wave height estimates from state-modeled scenarios for areas not covered by NOAA's forecast models, and clarifying which regions of the state were at greatest risk. Over the last year, state geoscientists have started to provide additional assistance: 1) working closely with NOAA to simplify their tsunami alert messaging and expand their forecast modeling coverage; 2) creating "playbooks" containing information from existing tsunami scenarios for local emergency managers to reference during an event; and, 3) developing a state-level information "clearinghouse" and pre-tsunami field response team to assist local officials as well as observe and report tsunami effects. Activities of geoscientists were expanded during the more recent Tsunami Advisory on February 27, 2010, including deploying a geologist from the California Geological Survey as a field observer who provided information back to emergency managers.

Pharmacist prescriptive authority for smoking cessation medications in the United States.

PubMed

Adams, Alex J; Hudmon, Karen Suchanek

To characterize the status of state laws regarding the expansion of pharmacists' prescriptive authority for smoking cessation medications and to summarize frequently asked questions and answers that arose during the associated legislative debates. Legislative language was reviewed and summarized for all states with expanded authority, and literature supporting the pharmacist's capacity for an expanded role in smoking cessation is described. The core elements of autonomous tobacco cessation prescribing models for pharmacists vary across states. Of 7 states that currently have fully or partially delineated protocols, 4 states (Colorado, Idaho, Indiana, New Mexico) include all medications approved by the U.S. Food and Drug Administration for smoking cessation, and 3 (Arizona, California, Maine) include nicotine replacement therapy products only. The state protocol in Oregon is under development. Most states specify minimum cessation education requirements and define specific elements (e.g., patient screening, cessation intervention components, and documentation requirements) for the autonomous prescribing models. Through expanded authority and national efforts to advance the tobacco cessation knowledge and skills of pharmacy students and licensed pharmacists, the profession's role in tobacco cessation has evolved substantially in recent years. Eight states have created, or are in the process of creating, pathways for autonomous pharmacist prescriptive authority. States aiming to advance tobacco control strategies to help patients quit smoking might consider approaches like those undertaken in 8 states. Copyright © 2018 American Pharmacists Association®.

We studied female graduates of the Robert Wood Johnson Clinical Scholars Program (CSP, Class of 1984 to 1989) to explore and describe the complexity of creating balance in the life of mid-career academic woman physicians. We conducted and qualitatively analyzed (kappa 0.35 to 1.0 for theme identification among rater pairs) data from a semi-structured survey of 21 women and obtained their curricula vitae to quantify publications and grant support, measures of academic productivity. Sixteen of 21 (76%) women completed the survey. Mean age was 48 (range: 45 to 56). Three were full professors, 10 were associate professors, and 3 had left academic medicine. Eleven women had had children (mean 2.4; range: 1 to 3) and 3 worked part-time. From these data, the conceptual model expands on 3 key themes: (1) defining, navigating, and negotiating success, (2) making life work, and (3) making work work. The women who described themselves as satisfied with their careers (10/16) had clarity of values and goals and a sense of control over their time. Those less satisfied with their careers (6/16) emphasized the personal and professional costs of the struggle to balance their lives and described explicit institutional barriers to fulfillment of their potential. For this group of fellowship-prepared academic women physicians satisfaction is achieving professional and personal balance.

Development of an expanded-field irradiation technique using a gimbaled x-ray head

Ono, Tomohiro; Miyabe, Yuki, E-mail: miyabe@kuhp.kyoto-u.ac.jp; Yamada, Masahiro

Purpose: The Vero4DRT has a maximum field size of 150.0 × 150.0 mm. The purpose of the present study was to develop expanded-field irradiation techniques using the unique gimbaled x-ray head of the Vero4DRT and to evaluate the dosimetric characteristics thereof. Methods: Two techniques were developed. One features gimbal swing irradiation and multiple static segments consisting of four separate fields exhibiting 2.39° gimbal rotation around two orthogonal axes. The central beam axis for each piecewise-field is shifted 40 mm from the isocenters of the left–right (LR) and superior–inferior (SI) directions, and, thus, the irradiation field size is expanded to 230.8 × 230.8 mm. Adjacentmore » regions were created at the isocenter (a center-adjacent expandedfield) and 20 mm from the isocenter (an off-adjacent expandedfield). The field gaps or overlaps of combined piecewise-fields were established by adjustment of gimbal rotation and movement of the multileaf collimator (MLC). Another technique features dynamic segment irradiation in which the beam is delivered while rotating the gimbal. The dose profile is controlled by a combination of gimbal swing motion and opening and closing of the MLC. This enabled the authors to expand the irradiation field on the LR axis because the direction of MLC motion is parallel to that axis. A field 220.6 × 150.0 mm in dimensions was configured and examined. To evaluate the dosimetric characteristics of the expandedfields, films inserted into water-equivalent phantoms at depths of 50, 100, and 150 mm were irradiated and field sizes, penumbrae, flatness, and symmetry analyzed. In addition, the expanded-field irradiation techniques were applied to intensity-modulated radiation therapy (IMRT). A head-and-neck IMRT field, created using a conventional Linac (the Varian Clinac iX), was reproduced employing an expanded-field of the Vero4DRT. The simulated dose distribution for the expanded-IMRT field was compared to the measured dose distribution. Results: The field sizes, penumbrae, flatness, and symmetry of the center- and off-adjacent expanded-fields were 230.2–232.1 mm, 6.8–10.7 mm, 2.3%–5.1%, and −0.5% to −0.4%, respectively, at a depth of 100 mm. Similarly, the field sizes, penumbrae, flatness, and symmetry of dynamic segment irradiation on the LR axis were 219.2 mm, 6.0–6.2 mm, 3.4%, and −0.1%, respectively, at a depth of 100 mm. In the area of expanded-IMRT dose distribution, the passing rate of 5% dose difference was 85.8% between measurements and simulation, and the 3%/3 mm gamma passing rate was 96.4%. Conclusions: Expanded-field irradiation techniques were developed using a gimbaled x-ray head. The techniques effectively extend target areas, as required when whole-breast irradiation or head-and-neck IMRT is contemplated.« less

Promotor(a)s, the organizations in which they work, and an emerging paradox: how organizational structure and scope impact promotor(a)s' work.

PubMed

May, Marlynn L; Contreras, Ricardo B

2007-07-01

To analyze how organizational structures and scope (geographic and programmatic) generate dissonance between the organization and its workers, creating a paradox with policy implications for access to health care in hard-to-reach populations. The workers are lay community health workers called promotor(a)s. The organizations are community based organizations in which the promotor(a)s work, either as volunteers, part-time or as full-time wage staff. Ethnographic study of 12 organizations and their promotor(a)s. Data gathering included interviews with organization directors, promotor(a)s, service providers working with the organizations, and community residents served by the organizations and workers. In addition, promotor(a)s were observed in the course of their work. Sampling was a non-probability, snowball procedure for identifying the organizations and the workers within them. A paradox is emerging between (a) promotor(a)s who perceive their work to be locally focused and tightly integrated with the communities they serve and live in, and (b) the employing organizations that are expanding in geographical and programmatic scope because the work promotor(a)s do is in increasing demand by agencies and funding sources external to the communities served. The paradox potentially threatens to undermine and transform the work and working environment of the promotor(a)s. The challenge is to find a balance that will sustain a workable and working relationship among the organization, the workers, and the communities served. Care is needed in setting out policies that translate the paradox into greater congruence among organization, workers and communities. Policy needs discussed focus on (a) worker training, (b) worker employment and deployment, and (c) funding source recognition of the paradox.

2013 - JPL's Snow Data System Year in Review

NASA Astrophysics Data System (ADS)

Goodale, C. E.; Painter, T. H.; Mattmann, C. A.; Brodzik, M.; Rittger, K. E.; Burgess, A.

2013-12-01

2013 has been a big year for JPL's Snow Data Processing System. This year our efforts have been focused on supporting the Colorado Basin River Forecast Center, working on products in the Western United States and Alaska for the National Climate Assessment, as well as research efforts in the Hindu Kush Himalaya Region of Asia through the generation and publication of our MODSCAG, MODDRFS and MODICE products. We have revisited the processing stream for our snow properties products as we expand to global coverage providing a higher quality, consistent dataset. We have enabled lossless compression as well as using more efficient data types for our data arrays. This has enabled our archive to expand its coverage while conserving disk space, which comes with the added benefit of making the data downloads smaller and faster. Storage and compression aren't the only changes we have made; there have also been several improvements with cloud masking and missing data identification. These improvements have resulted in products that are smaller and more concise. Our source for MOD09GA data is the LP.DAAC. In June of this year the DAAC switched from an FTP server to HTTP. Our team has been able to adapt to this change by using NASA's ECHO Catalog to search for links to download the MOD09GA HDF files our processing pipeline uses to create the SCAG and DRFS products. We looked at using Reverb, but they limit the search results to only 2000 granules, where our typical granule count for a single tile exceeds 4000. We would like to share our improvements to the output products, the lessons we learned from the DAAC changing to HTTP and how others can learn from us, and share the tools we have created. Our plan is to also show our current archive coverage of products, and where we will are planning to process data in 2014 and beyond.

AtomDB: Expanding an Accessible and Accurate Atomic Database for X-ray Astronomy

NASA Astrophysics Data System (ADS)

Smith, Randall

Since its inception in 2001, the AtomDB has become the standard repository of accurate and accessible atomic data for the X-ray astrophysics community, including laboratory astrophysicists, observers, and modelers. Modern calculations of collisional excitation rates now exist - and are in AtomDB - for all abundant ions in a hot plasma. AtomDB has expanded beyond providing just a collisional model, and now also contains photoionization data from XSTAR as well as a charge exchange model, amongst others. However, building and maintaining an accurate and complete database that can fully exploit the diagnostic potential of high-resolution X-ray spectra requires further work. The Hitomi results, sadly limited as they were, demonstrated the urgent need for the best possible wavelength and rate data, not merely for the strongest lines but for the diagnostic features that may have 1% or less of the flux of the strong lines. In particular, incorporation of weak but powerfully diagnostic satellite lines will be crucial to understanding the spectra expected from upcoming deep observations with Chandra and XMM-Newton, as well as the XARM and Athena satellites. Beyond incorporating this new data, a number of groups, both experimental and theoretical, have begun to produce data with errors and/or sensitivity estimates. We plan to use this to create statistically meaningful spectral errors on collisional plasmas, providing practical uncertainties together with model spectra. We propose to continue to (1) engage the X-ray astrophysics community regarding their issues and needs, notably by a critical comparison with other related databases and tools, (2) enhance AtomDB to incorporate a large number of satellite lines as well as updated wavelengths with error estimates, (3) continue to update the AtomDB with the latest calculations and laboratory measurements, in particular velocity-dependent charge exchange rates, and (4) enhance existing tools, and create new ones as needed to increase the functionality of, and access to, AtomDB.

Creating Community Responsibility for Child Protection: Possibilities and Challenges

PubMed Central

Daro, Deborah; Dodge, Kenneth A.

2013-01-01

Summary Deborah Daro and Kenneth Dodge observe that efforts to prevent child abuse have historically focused on directly improving the skills of parents who are at risk for or engaged in maltreatment. But, as experts increasingly recognize that negative forces within a community can overwhelm even well-intentioned parents, attention is shifting toward creating environments that facilitate a parent’s ability to do the right thing. The most sophisticated and widely used community prevention programs, say Daro and Dodge, emphasize the reciprocal interplay between individual-family behavior and broader neighborhood, community, and cultural contexts. The authors examine five different community prevention efforts, summarizing for each both the theory of change and the empirical evidence concerning its efficacy. Each program aims to enhance community capacity by expanding formal and informal resources and establishing a normative cultural context capable of fostering collective responsibility for positive child development. Over the past ten years, researchers have explored how neighborhoods influence child development and support parenting. Scholars are still searching for agreement on the most salient contextual factors and on how to manipulate these factors to increase the likelihood parents will seek out, find, and effectively use necessary and appropriate support. The current evidence base for community child abuse prevention, observe Daro and Dodge, offers both encouragement and reason for caution. Although theory and empirical research suggest that intervention at the neighborhood level is likely to prevent child maltreatment, designing and implementing a high-quality, multifaceted community prevention initiative is expensive. Policy makers must consider the trade-offs in investing in strategies to alter community context and those that expand services for known high-risk individuals. The authors conclude that if the concept of community prevention is to move beyond the isolated examples examined in their article, additional conceptual and empirical work is needed to garner support from public institutions, community-based stakeholders, and local residents.

Impact of a poka-yoke device on job performance of individuals with cognitive impairments.

PubMed

Erlandson, R F; Noblett, M J; Phelps, J A

1998-09-01

Job performance and production related issues are important not only to successful vocational training and ultimate job placement for individuals with cognitive disabilities, but also for their ability to have expanded vocational options. This study hypothesized that the application of Kaizen philosophy, and poka-yoke techniques in particular, could create job opportunities and improve productivity of individuals with cognitive disabilities. Poka-yoke or error-proofing techniques are part of the collection of Kaizen techniques. Kaizen refers to continuous improvement in performance, cost/effectiveness, and quality. Kaizen strives to empower the worker, increase worker satisfaction, facilitate a sense of accomplishment, and thereby create pride-of-work. These techniques typically reduce the physical and cognitive demands of a task and thereby render the task more accessible. The job was a fuel clamp assembly. A redesigned assembly fixture was the poka-yoke intervention. Consistent with poka-yoke principles, the intervention improved the productivity of everyone attempting the assembly. In particular, the workers in this study showed an 80% increase in productivity and an average percent error drop from 52% to about 1% after the process redesign. Furthermore, the workers showed improved morale, self-esteem, and pride-of-work. Prior to the process redesign, only the higher functioning workers could successfully perform the assembly. After the redesign a greater number of workers could successfully perform the assembly. These results not only validated the study hypothesis, but demonstrated that the success facilitated by applying Kaizen techniques had similar results with individuals with cognitive disabilities as with nondisabled workers.

`Dem DEMs: Comparing Methods of Digital Elevation Model Creation

NASA Astrophysics Data System (ADS)

Rezza, C.; Phillips, C. B.; Cable, M. L.

2017-12-01

Topographic details of Europa's surface yield implications for large-scale processes that occur on the moon, including surface strength, modification, composition, and formation mechanisms for geologic features. In addition, small scale details presented from this data are imperative for future exploration of Europa's surface, such as by a potential Europa Lander mission. A comparison of different methods of Digital Elevation Model (DEM) creation and variations between them can help us quantify the relative accuracy of each model and improve our understanding of Europa's surface. In this work, we used data provided by Phillips et al. (2013, AGU Fall meeting, abs. P34A-1846) and Schenk and Nimmo (2017, in prep.) to compare DEMs that were created using Ames Stereo Pipeline (ASP), SOCET SET, and Paul Schenk's own method. We began by locating areas of the surface with multiple overlapping DEMs, and our initial comparisons were performed near the craters Manannan, Pwyll, and Cilix. For each region, we used ArcGIS to draw profile lines across matching features to determine elevation. Some of the DEMs had vertical or skewed offsets, and thus had to be corrected. The vertical corrections were applied by adding or subtracting the global minimum of the data set to create a common zero-point. The skewed data sets were corrected by rotating the plot so that it had a global slope of zero and then subtracting for a zero-point vertical offset. Once corrections were made, we plotted the three methods on one graph for each profile of each region. Upon analysis, we found relatively good feature correlation between the three methods. The smoothness of a DEM depends on both the input set of images and the stereo processing methods used. In our comparison, the DEMs produced by SOCET SET were less smoothed than those from ASP or Schenk. Height comparisons show that ASP and Schenk's model appear similar, alternating in maximum height. SOCET SET has more topographic variability due to its decreased smoothing, which is borne out by preliminary offset calculations. In the future, we plan to expand upon this preliminary work with more regions of Europa, continue quantifying the height differences and relative accuracy of each method, and generate more DEMs to expand our available comparison regions.

Does the home environment and the sex of the child modify the adverse effects of prenatal exposure to chlorpyrifos on child working memory?

PubMed Central

Horton, Megan K.; Kahn, Linda G.; Perera, Frederica; Barr, Dana Boyd; Rauh, Virginia

2013-01-01

Prenatal exposure to chlorpyrifos (CPF), an organophosphorus insecticide, has long been associated with delayed neurocognitive development and most recently with decrements in working memory at age 7. In the current paper, we expanded the previous work on CPF to investigate how additional biological and social environmental factors might create or explain differential neurodevelopmental susceptibility, focusing on main and moderating effects of the quality of the home environment (HOME) and child sex. We evaluate how the quality of the home environment (specifically, parental nurturance and environmental stimulation) and child sex interact with the adverse effects of prenatal CPF exposure on working memory at child age 7 years. We did not observe a remediating effect of a high quality home environment (either parental nurturance or environmental stimulation) on the adverse effects of prenatal CPF exposure on working memory. However, we detected a borderline significant interaction between prenatal exposure to CPF and child sex (B (95% CI) for interaction term = −1.714 (−3.753 to 0.326)) suggesting males experience a greater decrement in working memory than females following prenatal CPF exposure. In addition, we detected a borderline interaction between parental nurturance and child sex (B (95% CI) for interaction term = 1.490 (−0.518 to 3.499)) suggesting that, in terms of working memory, males benefit more from a nurturing environment than females. To our knowledge, this is the first investigation into factors that may inform an intervention strategy to reduce or reverse the cognitive deficits resulting from prenatal CPF exposure.

The Working Women's Forum: organizing for credit and change.

PubMed

Chen, M

1983-01-01

The Working Women's Forum (WWF), established in Madras in 1978, has brought together over 13,000 poor urban women around the issue of credit. Most women who live in the slums of Madras work as small-scale traders and vendors, their earnings often providing over half the family income. Interviews with these women revealed that their primary concern was increasing their earning capacity. The WWF was set up to enable these women to obtain low interest loans to expand their businesses. The key element in the WWF structure is the neighborhood loan group, comprised of 10-20 women from the same area who act as mutual guarantors for the loans of all group members. Over 7000 women have received loans and the repayment rate has been over 90%. About 2800 new jobs or businesses have been created, and earnings have increased an average of 50% in existing enterprises. Women report that they are eating better quality and more varied foods as a result of their increased income. The WWF is expanding its activities to address the political and social problems of working women as well. The Forum operates day care centers, skills training centers, and remedial classes for schoolchildren. In 1980 the WWF launched a family planning program in which field workers (who are drawn from the WWF membership and paid $18 per month) disseminate information on health, nutrition, and family planning to families in their communities. According to a staff member, this program was an outcome of the realization that "income generation and large families do not go together." The WWF also promotes intercaste, no dowry marriages and lobbies for public services. Women have become more confident of the possibility of gaining control over their lives, including their fertility. The WWF experience demonstrates that an organization does not need a lot of money, educated staff, or technical expertise to reach poor women. The Forum's success is attributed to its selection of one critical issue, utilization of local leadership, organization of women around existing neighborhood ties, and decentralized management.

Cantera Integration with the Toolbox for Modeling and Analysis of Thermodynamic Systems (T-MATS)

Lavelle, Thomas M.; Chapman, Jeffryes W.; May, Ryan D.; Litt, Jonathan S.; Guo, Ten-Huei

2014-01-01

NASA Glenn Research Center (GRC) has recently developed a software package for modeling generic thermodynamic systems called the Toolbox for the Modeling and Analysis of Thermodynamic Systems (T-MATS). T-MATS is a library of building blocks that can be assembled to represent any thermodynamic system in the Simulink(Registered TradeMark) (The MathWorks, Inc.) environment. These elements, along with a Newton Raphson solver (also provided as part of the T-MATS package), enable users to create models of a wide variety of systems. The current version of T-MATS (v1.0.1) uses tabular data for providing information about a specific mixture of air, water (humidity), and hydrocarbon fuel in calculations of thermodynamic properties. The capabilities of T-MATS can be expanded by integrating it with the Cantera thermodynamic package. Cantera is an object-oriented analysis package that calculates thermodynamic solutions for any mixture defined by the user. Integration of Cantera with T-MATS extends the range of systems that may be modeled using the toolbox. In addition, the library of elements released with Cantera were developed using MATLAB native M-files, allowing for quicker prototyping of elements. This paper discusses how the new Cantera-based elements are created and provides examples for using T-MATS integrated with Cantera.

For independent electric producers, the new energy law opens wide the gate to the future. It does not give an entitlement or a subsidy; merely the freedom to expand - along with utilities - electricity's share of the next century's energy market. If anything, the new law, by removing investment barriers and creating the right to transmission access, affirms the potential of electrical generation and urges us all to get on with the job. It underscores the most powerful forces for future growth: the increasing demand for more electric power, greater production at less cost, and lessening demand on themore » environment's resources. With half-century-old barriers to broader production finally down, the real action now belongs to the regulators. It's one thing to pass a bill. It's quite another to make it work. The reform bill does not deregulate, but essentially defines public policy objectives (competitive markets), creates a framework to develop them, and vest responsibility for the regulation of the generation and sale of power where it belongs: with state public utility commissions and the FERC. It is going to be up to them to set the limits of the market, and to set the pace of expansion; in other words, to rearrange the play to achieve the bill's objective.« less

Thermonuclear inverse magnetic pumping power cycle for stellarator reactor

DOEpatents

Ho, Darwin D.; Kulsrud, Russell M.

1991-01-01

The plasma column in a stellarator is compressed and expanded alternatively in minor radius. First a plasma in thermal balance is compressed adiabatically. The volume of the compressed plasma is maintained until the plasma reaches a new thermal equilibrium. The plasma is then expanded to its original volume. As a result of the way a stellarator works, the plasma pressure during compression is less than the corresponding pressure during expansion. Therefore, negative work is done on the plasma over a complete cycle. This work manifests itself as a back-voltage in the toroidal field coils. Direct electrical energy is obtained from this voltage. Alternatively, after the compression step, the plasma can be expanded at constant pressure. The cycle can be made self-sustaining by operating a system of two stellarator reactors in tandem. Part of the energy derived from the expansion phase of a first stellarator reactor is used to compress the plasma in a second stellarator reactor.

The aim of this paper is to create adaptive structures capable of self-expanding and self-shrinking by means of four-dimensional printing technology. An actuator unit is designed and fabricated directly by printing fibers of shape memory polymers (SMPs) in flexible beams with different arrangements. Experiments are conducted to determine thermo-mechanical material properties of the fabricated part revealing that the printing process introduced a strong anisotropy into the printed parts. The feasibility of the actuator unit with self-expanding and self-shrinking features is demonstrated experimentally. A phenomenological constitutive model together with analytical closed-form solutions are developed to replicate thermo-mechanical behaviors of SMPs. Governing equations of equilibrium are developed for printed structures based on the non-linear Green-Lagrange strain tensor and solved implementing a finite element method along with an iterative incremental Newton-Raphson scheme. The material-structural model is then applied to digitally design and print SMP adaptive lattices in planar and tubular shapes comprising a periodic arrangement of SMP actuator units that expand and then recover their original shape automatically. Numerical and experimental results reveal that the proposed planar lattice as meta-materials can be employed for plane actuators with self-expanding/shrinking features or as structural switches providing two different dynamic characteristics. It is also shown that the proposed tubular lattice with a self-expanding/shrinking mechanism can serve as tubular stents and grippers for bio-medical or piping applications.

Medicare's private plans: a report card on Medicare Advantage.

PubMed

Gold, Marsha

2009-01-01

With higher payments and expanded private-plan authority, Medicare Advantage (MA) has caused the market to grow. One in three Medicare beneficiaries with Part D now gets this coverage through MA. Analysis of the sources of and reasons for enrollment growth suggest a troubling report card. Clearly, the Medicare Modernization Act (MMA) has expanded choice and the private-sector role. But it also has added to Medicare's complexity and costs and has created potential inequities, without apparent improvements in quality. However the debate ends, a stronger system of performance monitoring and accountability is needed to meet Medicare's essential fiduciary requirements and oversight responsibilities.

To start on the path to a career in science, technology, engineering, or mathematics (STEM), girls must take appropriate prerequisite-to-college mathematics and science courses when they are 15 to 18 years old. The Expanding Your Horizons in Science, Engineering, and Mathematics (EYH) conferences are one-day conferences for girls aged 12 to 18, designed to encourage girls towards a STEM career. These conferences engage schoolgirls in enjoyable hands-on STEM activities, created and led by women STEM professionals. This paper describes the history of EYH conferences, what happens at one, the impact of an EYH conference on the girls, and how to start one.

'Laguna Hollow'Undisturbed

NASA Technical Reports Server (NTRS)

2004-01-01

This image shows the patch of soil at the bottom of the shallow depression dubbed 'Laguna Hollow' where the Mars Exploration Rover Spirit will soon begin trenching. Scientists are intrigued by the clustering of small pebbles and the crack-like fine lines, which indicate a coherent surface that expands and contracts. A number of processes can cause materials to expand and contract, including cycles of heating and cooling; freezing and thawing; and rising and falling of salty liquids within a substance. This false-color image was created using the blue, green and infrared filters of the rover's panoramic camera. Scientists chose this particular combination of filters to enhance the heterogeneity of the martian soil.

Control of estrus and ovulation in beef heifers.

Patterson, David J; Thomas, Jordan M; Martin, Neal T; Nash, Justin M; Smith, Michael F

2013-11-01

Expanded use of artificial insemination (AI) and/or adoption of emerging reproductive technologies for beef heifers and cows require precise methods of estrous-cycle control. New protocols for inducing and synchronizing a fertile estrus in replacement beef heifers and postpartum beef cows in which progestins are used provide new opportunities for beef producers to synchronize estrus and ovulation and to facilitate fixed-time AI. This article reviews the various estrous synchronization protocols currently available for use in replacement beef heifers. New methods of inducing and synchronizing estrus now create the opportunity to significantly expand the use of AI in the United States cowherd. Copyright © 2013 Elsevier Inc. All rights reserved.

Esophagojejunal Anastomosis Fistula, Distal Esophageal Stenosis, and Metalic Stent Migration after Total Gastrectomy

PubMed Central

Al Hajjar, Nadim; Popa, Calin; Al-Momani, Tareg; Margarit, Simona; Graur, Florin; Tantau, Marcel

2015-01-01

Esophagojejunal anastomosis fistula is the main complication after a total gastrectomy. To avoid a complex procedure on friable inflamed perianastomotic tissues, a coated self-expandable stent is mounted at the site of the anastomotic leak. A complication of stenting procedure is that it might lead to distal esophageal stenosis. However, another frequently encountered complication of stenting is stent migration, which is treated nonsurgically. When the migrated stent creates life threatening complications, surgical removal is indicated. We present a case of a 67-year-old male patient who was treated at our facility for a gastric adenocarcinoma which developed, postoperatively, an esophagojejunostomy fistula, a distal esophageal stenosis, and a metallic coated self-expandable stent migration. To our knowledge, this is the first reported case of an esophagojejunostomy fistula combined with a distal esophageal stenosis as well as with a metallic coated self-expandable stent migration.

SPOT-ligand 2: improving structure-based virtual screening by binding-homology search on an expanded structural template library.

PubMed

Litfin, Thomas; Zhou, Yaoqi; Yang, Yuedong

2017-04-15

The high cost of drug discovery motivates the development of accurate virtual screening tools. Binding-homology, which takes advantage of known protein-ligand binding pairs, has emerged as a powerful discrimination technique. In order to exploit all available binding data, modelled structures of ligand-binding sequences may be used to create an expanded structural binding template library. SPOT-Ligand 2 has demonstrated significantly improved screening performance over its previous version by expanding the template library 15 times over the previous one. It also performed better than or similar to other binding-homology approaches on the DUD and DUD-E benchmarks.

Kenyon, Kristy L.; Onorato, Morgan E.; Gottesman, Alan J.; Hoque, Jamila; Hoskins, Sally G.

2016-01-01

CREATE (Consider, Read, Elucidate the hypotheses, Analyze and interpret the data, and Think of the next Experiment) is an innovative pedagogy for teaching science through the intensive analysis of scientific literature. Initiated at the City College of New York, a minority-serving institution, and regionally expanded in the New York/New Jersey/Pennsylvania area, this methodology has had multiple positive impacts on faculty and students in science, technology, engineering, and mathematics courses. To determine whether the CREATE strategy is effective at the community college (2-yr) level, we prepared 2-yr faculty to use CREATE methodologies and investigated CREATE implementation at community colleges in seven regions of the United States. We used outside evaluation combined with pre/postcourse assessments of students to test related hypotheses: 1) workshop-trained 2-yr faculty teach effectively with the CREATE strategy in their first attempt, and 2) 2-yr students in CREATE courses make cognitive and affective gains during their CREATE quarter or semester. Community college students demonstrated positive shifts in experimental design and critical-thinking ability concurrent with gains in attitudes/self-rated learning and maturation of epistemological beliefs about science.

Rapid direct conversion of Cu2-xSe to CuAgSe nanoplatelets via ion exchange reactions at room temperature

NASA Astrophysics Data System (ADS)

Moroz, N. A.; Olvera, A.; Willis, G. M.; Poudeu, P. F. P.

2015-05-01

The use of template nanostructures for the creation of photovoltaic and thermoelectric semiconductors is becoming a quickly expanding synthesis strategy. In this work we report a simple two-step process enabling the formation of ternary CuAgSe nanoplatelets with a great degree of control over the composition and shape. Starting with hexagonal nanoplatelets of cubic Cu2-xSe, ternary CuAgSe nanoplatelets were generated through a rapid ion exchange reaction at 300 K using AgNO3 solution. The Cu2-xSe nanoplatelet template and the final CuAgSe nanoplatelets were analyzed by electron microscopy and X-ray diffraction (XRD). It was found that both the low temperature pseudotetragonal and the high temperature cubic forms of CuAgSe phase were created while maintaining the morphology of the Cu2-xSe nanoplatelet template. Thermal and electronic transport measurements of hot-pressed pellets of the synthesized CuAgSe nanoplatelets showed a drastic reduction in the thermal conductivity and a sharp transition from n-type (S = -45 μV K-1) to p-type (S = +200 μV K-1) semiconducting behavior upon heating above the structural transition from the low temperature orthorhombic to the high temperature super-ionic cubic phase. This simple reaction process utilizing a template nanostructure matrix represents an energy efficient, cost-efficient, and versatile strategy to create interesting materials with lower defect density and superior thermoelectric performance.The use of template nanostructures for the creation of photovoltaic and thermoelectric semiconductors is becoming a quickly expanding synthesis strategy.

Policies to Spur Energy Access. Executive Summary; Volume 1, Engaging the Private Sector in Expanding Access to Electricity; Volume 2, Case Studies to Public-Private Models to Finance Decentralized Electricity Access

DOE Office of Scientific and Technical Information (OSTI.GOV)

Walters, Terri; Rai, Neha; Esterly, Sean

Government policy is one of the most important factors in engaging the private sector in providing universal access to electricity. In particular, the private sector is well positioned to provide decentralized electricity products and services. While policy uncertainty and regulatory barriers can keep enterprises and investors from engaging in the market, targeted policies can create opportunities to leverage private investment and skills to expand electricity access. However, creating a sustainable market requires policies beyond traditional electricity regulation. The report reviews the range of policy issues that impact the development and expansion of a market for decentralized electricity services from establishingmore » an enabling policy environment to catalyzing finance, building human capacity, and integrating energy access with development programs. The case studies in this report show that robust policy frameworks--addressing a wide range of market issues--can lead to rapid transformation in energy access. The report highlights examples of these policies in action Bangladesh, Ethiopia, Mali, Mexico, and Nepal.« less

Characterization of Flow and Ohm's Law in the Rotating Wall Machine

NASA Astrophysics Data System (ADS)

Hannum, David; Brookhart, M.; Forest, C. B.; Kendrick, R.; Mengin, G.; Paz-Soldan, C.

2010-11-01

The rotating wall machine is a linear screw-pinch built to study the role of different electromagnetic boundary conditions on the Resistive Wall Mode (RWM). Its plasma is created by an array of electrostatic washer guns which can be biased to discharge up to 1 kA of current each. Individual flux ropes from the guns shear, merge, and expand into a 20 cm diameter, ˜1 m long plasma column. Langmuir (singletip) and tri-axial B-dot probes move throughout the column to measure radial and axial profiles of key plasma parameters. As the plasma current increases, more H2 fuel is ionized, raising ne to 5 x10^20 m-3 while Te stays at a constant 3 eV. The electron density expands to the wall while the current density (Jz) stays pinched to the central axis. E xB and diamagnetic drifts create radially and axially sheared plasma rotation. Plasma resistivity follows the Spitzer model in the core while exceeding it at the edge. These measurements improve the model used to predict the RWM growth rate.

English semantic word-pair norms and a searchable Web portal for experimental stimulus creation.

Buchanan, Erin M; Holmes, Jessica L; Teasley, Marilee L; Hutchison, Keith A

2013-09-01

As researchers explore the complexity of memory and language hierarchies, the need to expand normed stimulus databases is growing. Therefore, we present 1,808 words, paired with their features and concept-concept information, that were collected using previously established norming methods (McRae, Cree, Seidenberg, & McNorgan Behavior Research Methods 37:547-559, 2005). This database supplements existing stimuli and complements the Semantic Priming Project (Hutchison, Balota, Cortese, Neely, Niemeyer, Bengson, & Cohen-Shikora 2010). The data set includes many types of words (including nouns, verbs, adjectives, etc.), expanding on previous collections of nouns and verbs (Vinson & Vigliocco Journal of Neurolinguistics 15:317-351, 2008). We describe the relation between our and other semantic norms, as well as giving a short review of word-pair norms. The stimuli are provided in conjunction with a searchable Web portal that allows researchers to create a set of experimental stimuli without prior programming knowledge. When researchers use this new database in tandem with previous norming efforts, precise stimuli sets can be created for future research endeavors.

Gas expanded polymer process to anneal nanoparticle dispersion in thin films

DOE PAGES

Ambuken, Preejith V.; Stretz, Holly A.; Dadmun, Mark; ...

2015-04-21

A spin-coating solution comprising poly(3-hexylthiophene) (P3HT) and phenyl-C61-butyric acid methyl ester (PCBM) nanoparticles used to create organic photovoltaic (OPV) active layers have been shown to adopt a non-uniform concentration profile across the thin film dimension. This inhomogeneous distribution can reduce the efficiency of the device. For our new process, gas expanded polymer (GXP) annealing, is applied to P3HT/PCBM thin film blends, enabling the distribution of the PCBM nanoparticles to be manipulated by varying the GXP processing conditions. Films of 50 nm thickness (nominally) created by spin casting a blend of P3HT mixed with PCBM were annealed by oscillatory GXP andmore » GXP at constant pressure using high pressure CO 2. An increase in P3HT crystallinity (detected by X-ray diffraction and UV-vis spectroscopy) along with a more uniform distribution of PCBM nanoparticles in the thickness dimension, as interpreted from neutron reflectivity measurements, were observed after oscillatory GXP annealing. In addition, static water contact angles suggest that the film/air interface is enriched in PCBM relative to the as-cast film. Finally, these results demonstrate that GXP annealing, which is commercially scalable, can be successfully used to create a uniform distribution of PCBM nanoparticles across the thickness dimension in a P3HT thin film.« less

Studies of solution-processed organic light-emitting diodes and their materials

DOE Office of Scientific and Technical Information (OSTI.GOV)

Hellerich, Emily

2013-01-01

A hitherto unexplored approach is presented in which a small molecule is used as a host to polymer guests in solution-processed OLEDs. We find that the small molecule host results in much more efficient devices than the often-used alternative polymer host when used for the guests presented. It is likely that nano- and microstructural differences between the hosts contribute to the improvements, which highlights some interesting characteristics that can help to better understand the nature of these mixtures. A number of the guests used in this study were newly synthesized benzobisoxazole-based copolymers. New organic copolymers are presented that are basedmore » on the chemical structure of benzobisoxazoles, which have been shown in the past to have good electron transporting properties. The novel concept in this publication pertains to a change in the direction of polymerization, also known as the conjugation pathway, which we show increases the emission efficiency. This work highlights a unique and useful property of organic semiconducting materials in that they can be synthesized to create the desired characteristics. Earlier work is described that kick-started in our research group the use of small molecules in solution-processed OLEDs. Originally these devices were to be used in magnetoresistance studies, but the project took a different path when the devices were more efficient than expected. The efficient use of small molecules in solution-processed OLEDs is highlighted, which at the time was not often the case. Also, the important observation of the effect of solvent choice on the resultant film is emphasized, with discussion of the likely cause of these effects. Microcavity OLEDs are introduced in which the transparent anode ITO is replaced with semi-transparent thin silver, which creates an optical cavity within the devices. The goal was to expand a previous work that created an on-chip spectrometer covering wavelengths 493 to 639 nm. In this case, a spin-coated mixed emitting layer (EML) is used, consisting of a polymer and a small molecule that both emit in the near UV and blue. The resulting combined spectra gives a wide band that can be used to create narrow microcavity emission peaks of 373 to 469 nm, depending on the device thickness (i.e. the cavity’s optical length). In the process of this effort, the mixed EML presented interesting complexities that we attempt to explain via simulation and morphology study.« less

Juggling work and elder caregiving: work-life balance for aging American workers.

PubMed

Pitsenberger, D Jeanne

2006-04-01

As the American work force ages, the demands of caring for aging relatives increase. Family caregiving often interferes with workplace responsibilities, creating physical, emotional, and financial stress for caregivers. Employers must address the productivity losses created by absenteeism of workers who struggle with work-life issues created by caregiving roles. Occupational health nurses must understand the factors that affect workers in their caregiving roles and make appropriate nursing interventions. They are in key positions to help aging employees and their employers face the increased demands on work-life balance created by elder caregiving.

Design and preliminary testing of a novel skin expander for total ear reconstruction in a rabbit model.

2016-01-01

Ear reconstruction is one of the most complicated and challenging techniques in plastic surgery because of the histologic and anatomic properties of the ear. Success depends on fitting the auriform cartilage scaffold into the overlying skin, but current approaches can just give results that are not lifelike and can lead to complications. A novel double-capsule, double-valve plastic ear expander was designed and implanted subcutaneously on either side of the dorsum of six New Zealand white rabbits (two expanders per rabbit). The outer capsule was expanded by injecting approximately 120 mL of physiological saline, then withdrawing the liquid on two occasions. Next, the ear-shaped inner capsule was filled with high-hardness plaster, and the external capsule was emptied such that the expanded skin flap and external capsule responded to the negative pressure and closed over the ear-shaped inner capsule. As a result, the skin flap adopted an ear shape. The ear expander was left in place for 4 wk, removed with the help of a mini-incision, and stripped of its fibrous capsule. To simulate human ear reconstruction, the expander was replaced with an auriform silicone prosthesis, and the effects of auricular reconstruction were observed dynamically. All 12 skin flaps maintained abundant blood supply, created a clear outline of the ear framework, and produced a lifelike result. No complications were observed during the 4-wk observation period. The expanded skin flaps described here can mold to the desired contours and appear lifelike, as well as maintain abundant blood supply. This may provide a simpler approach to total ear reconstruction that reduces risk of complications. Copyright © 2016 Elsevier Inc. All rights reserved.

Factors associated with pharmacists' perceptions of their working conditions and safety and effectiveness of patient care.

2016-01-01

In recent years, the role of pharmacists has changed, as have various provincial legislations, which now allow pharmacists to provide additional health services to patients. With these changes comes growing concern about how well the current pharmacy working environment is adapting and whether it may also be creating work-related stress that may contribute to potentially unsafe practices of patient care. To characterize the current working conditions of pharmacists in British Columbia, an online survey was developed and distributed to all College of Pharmacists of BC (CPBC) registrants by email. The survey consisted of questions on pharmacists' demographics, practice setting and perceptions of workplace conditions. Responses were collected from October 1 to November 10, 2013. All data were summarized using descriptive statistics, and regression models were constructed to assess the association between various factors and pharmacists' self-reported working conditions. Twenty-three percent (1241/5300) of pharmacists registered with the CPBC responded, with 78% working in the community pharmacy setting (58% chain, 19% independent). Pharmacists mostly disagreed with the statements that they had enough time for breaks or lunches or to do their jobs, as well as enough staffing support. Pharmacists' perceptions of their workplace environment were negatively associated with workplace-imposed advanced service quotas (for medication reviews, immunizations and prescription adaptations); being employed at chain store pharmacies, compared to independent pharmacies or hospitals/long-term care settings; and higher prescription volume. Pharmacists working in chain community pharmacies who are required to meet monthly quotas for expanded services reported a substantial negative impact on their working conditions and perceived safety of patient care.

Cooperation of return-to-work professionals: the challenges of multi-actor work disability management.

PubMed

Liukko, Jyri; Kuuva, Niina

2017-07-01

This article explores which concrete factors hinder or facilitate the cooperation of return-to-work (RTW) professionals in a complex system of multiple stakeholders. The empirical material consists of in-depth interviews with 24 RTW professionals from various organizations involved in work disability management in Finland. The interviews were analyzed using thematic content analysis. The study revealed several kinds of challenges in the cooperation of the professionals. These were related to two partly interrelated themes: communication and distribution of responsibility. The most difficult problems were connected to the cooperation between public employment offices and other stakeholders. However, the study distinguished notable regional differences depending primarily on the scale of the local network. The main areas of improvement proposed by the interviewees were related to better networking of case managers and expansion of expertise. The article argues for the importance of systematic networking and stresses the role of public employment services in the multi-actor management of work disabilities. The article contributes to existing work disability case management models by suggesting the employment administration system as an important component in addition to health care, workplace and insurance systems. The study also highlights the need for expansion of expertise in the field. Implications for Rehabilitation Cooperation between RTW professionals in public employment offices and other organizations involved in work disability management was considered inadequate. In order to improve the cooperation of RTW professionals, the stakeholders need to create more systematic ways of communication and networking with professionals in other organizations. There is a need to expand the expertise in work disability management and rehabilitation, partly by increasing the role of other professionals than physicians.

Sustainable water use and management options in a water-stressed river basin in Kenya

2017-04-01

Sustainable water resource is critical for maintaining healthy ecosystems and supporting socio-economic sectors. Hydro-climatic change and variability, population growth as well as new infrastructure developments create water security risks. Therefore, evidence-based management decisions are necessary to improve water security and meet the future water demands of multiple competing sectors. In this work we perform water resource modelling in order to investigate the impact of increasing water demand (expanding agriculture, booming industry, growing population) on the sustainable water use in Turkwel river basin, located in arid north-western Kenya. We test different management options to determine those that meet the water demands of the concerned sectors whilst minimising environmental impact. We perform scenario analysis using Water Evaluation And Planning (WEAP) model to explore different ranges of climate conditions, population growth rates, irrigation scale, reservoir operations, and economic development. The results can be used as a scientific guideline for the policy makers who decide the alternative management options that ensure the sustainable water use in the basin. The work is part of the REACH - improving water security for the poor program (http://reachwater.org.uk/), aiming to support a pathway to sustainable growth and poverty reduction

NASA's Public Participation Universe: Why and How the U.S. Space Agency Is Democratizing Its Approaches to Innovation

This paper analyzes NASA's increasing effort to invite greater public participation in its techno scientific work through open innovation methodologies. First we examine why NASA has expanded its use of these approaches, noting the roles of an intertwined set of forcing functions including budget constraints, the availability of technological resources, and committed individuals. Next we outline the strategies the agency has invoked to engage the public in research, technology development, and other activities to advance and shape NASA's mission. As we show, promoting greater public involvement has entailed facilitating the NASA workforce's familiarity with open innovation approaches as well as developing projects and creating outreach strategies appropriate to the envisioned participant base. We then discuss the wide variety of outcomes NASA's open innovation initiatives have yielded in support of NASA research and development objectives as well as benefits to participants and others. We conclude with a discussion of the remaining barriers to the use of open innovation techniques as a standard practice and the strategies in work to overcome those barriers so the full potential of a democratized approach to innovation can be realized.

The cumulative total of persons forced to leave their country for fear of persecution or organized violence reached an unprecedented 24.5 million by the end of 2015. Providing equitable access to appropriate health services for these highly diverse newcomers poses challenges for receiving countries. In this case study, we illustrate the importance of translating epidemiology into policy to address the health needs of refugees by highlighting examples of what works as well as identifying important policy-relevant gaps in knowledge. First, we formed an international working group of epidemiologists and health services researchers to identify available literature on the intersection of epidemiology, policy, and refugee health. Second, we created a synopsis of findings to inform a recommendation for integration of policy and epidemiology to support refugee health in the US and other high-income receiving countries. Third, we identified eight key areas to guide the involvement of epidemiologists in addressing refugee health concerns. The complexity and uniqueness of refugee health issues, and the need to develop sustainable management information systems, require epidemiologists to expand their repertoire of skills to identify health patterns among arriving refugees, monitor access to appropriately designed health services, address inequities, and communicate with policy makers and multidisciplinary teams.

2009-01-01

In many countries regulatory agencies have adopted safety guidelines, based on bioinformatics rules from the WHO/FAO and EFSA recommendations, to prevent potentially allergenic novel foods or agricultural products from reaching consumers. We created the Structural Database of Allergenic Proteins (SDAP, http://fermi.utmb.edu/SDAP/) to combine data that had previously been available only as flat files on Web pages or in the literature. SDAP was designed to be user friendly, to be of maximum use to regulatory agencies, clinicians, as well as to scientists interested in assessing the potential allergenic risk of a protein. We developed methods, unique to SDAP, to compare the physicochemical properties of discrete areas of allergenic proteins to known IgE epitopes. We developed a new similarity measure, the property distance (PD) value that can be used to detect related segments in allergens with clinical observed crossreactivity. We have now expanded this work to obtain experimental validation of the PD index as a quantitative predictor of IgE cross-reactivity, by designing peptide variants with predetermined PD scores relative to known IgE epitopes. In complementary work we show how sequence motifs characteristic of allergenic proteins in protein families can be used as fingerprints for allergenicity. PMID:19121639

Experiences of exclusion when living on a ventilator: reflections based on the application of Julia Kristeva's philosophy to caring science.

PubMed

Lindahl, Berit

2011-01-01

The research presented in this work represents reflections in the light of Julia Kristeva's philosophy concerning empirical data drawn from research describing the everyday life of people dependent on ventilators. It also presents a qualitative and narrative methodological approach from a person-centred perspective. Most research on home ventilator treatment is biomedical. There are a few published studies describing the situation of people living at home on a ventilator but no previous publications have used the thoughts in Kristeva's philosophy applied to this topic from a caring science perspective. The paper also addresses what a life at home on a ventilator may be like and will hopefully add some new aspects to the discussion of philosophical issues in nursing and the very essence of care. Kristeva's philosophy embraces phenomena such as language, abjection, body, and love, allowing her writings to make a fruitful contribution to nursing philosophy in that they strengthen, expand, and deepen a caring perspective. Moreover, her writings about revolt having the power to create hope add an interesting aspect to the work of earlier philosophers and nursing theorists. © 2010 Blackwell Publishing Ltd.

The APPL "Learning Map"

NASA Technical Reports Server (NTRS)

2005-01-01

Root Learning, a learning consulting organization with a background in strategic planning, recognizes the knowledge gap that frequently exists between a leadership team and the rest of an organization. Team members supposedly working toward the same goal don't always have the same vision as to where the organization is headed, and they may not understand how the piece they are accountable for fits into the big picture. To address these complex problems, Root Learning utilizes the age-old tools of sarcasm, metaphor and graphics (much in the same way that ASK uses a traditional storytelling format.) The company is best known for creating "Learning Maps" like this one: humorous drawings based on the inner workings of an organization. Their purpose is to put complex topics on the table, to stimulate discussion, and to ultimately give team members a common vision of where the organization is going and what role they personally play in getting there. APPL knows how effective it is to incorporate new and engaging techniques into its knowledge sharing programs. By collaborating with Root Learning, we were able to expand the knowledge of the organization and add one more of these techniques to our repertoire.

TAP Report - Southwest Idaho Juniper Working Group

DOE Office of Scientific and Technical Information (OSTI.GOV)

Gresham, Garold Linn

There is explicit need for characterization of the materials for possible commercialization as little characterization data exists. Pinyon-juniper woodlands are a major ecosystem type found in the Southwest and the Intermountain West regions of the United States including Nevada, Idaho and Oregon. These widespread ecosystems are characterized by the presence of several different species of pinyon and juniper as the dominant plant cover. Since the 1800s, pinyon-juniper woodlands have rapidly expanded their range at the expense of existing ecosystems. Additionally, existing woodlands have become denser, progressively creating potential fire hazards as seen in the Soda Fire, which burned more thanmore » 400 sq. miles. Land managers responsible for these areas often desire to reduce pinyon-juniper coverage on their lands for a variety of reasons, as stated in the Working Group objectives. However, the cost of clearing thinning pinyon-juniper stands can be prohibitive. One reason for this is the lack of utilization options for the resulting biomass that could help recover some of the cost of pinyon-juniper stand management. The goal of this TAP effort was to assess the feedstock characteristics of biomass from a juniper harvested from Owyhee County to evaluate possible fuel and conversion utilization options.« less

Currently, all main space industry players, such as Europe, USA, Russia, China, etc., are looking back again at the idea of Moon exploration building there a manned lunar base. Alongside with other world spacefaring nations, Yuzhnoye State Design Office with its long-time development experience, technological and intellectual potential, organized its own conceptual work on development of the Lunar Industry & Research Base. In the frames of conceptual project "Lunar Industrial & Research Base" were formed its appearance, preliminary configuration and infrastructure at different stages of operation, trajectory and flight scheme to the Moon, as well as terms of the project's realization, and main technical characteristics of the systems under development, such as space transportation system for crew and cargo delivery to lunar surface and return to Earth, standardized designs of lunar modules, lunar surface vehicles, etc. The "Lunar Industrial & Research Base" project's preliminary risk assessment has shown a high value of its overall risk due to the lack of reliable information about the Moon, technical risks, long-term development of its elements, very high financial costs and dependence on state support. This points to the fact that it is reasonable to create such a global project in cooperation with other countries. International cooperation will expand the capabilities of any nation, reduce risks and increase the success probability of automated or manned space missions. It is necessary to create and bring into operation practical mechanisms for long-term space exploration on a global scale. One of the ways to do this is to create a multinational agency which would include both state enterprises and private companies.

Burnout, depression, and suicidality among residents of all specialties have become a critical focus for the medical education community, especially among learners in graduate medical education. In 2017 the Accreditation Council for Graduate Medical Education (ACGME) updated the Common Program Requirements to focus more on resident wellbeing. To address this issue, one working group from the 2017 Resident Wellness Consensus Summit (RWCS) focused on wellness program innovations and initiatives in emergency medicine (EM) residency programs. Over a seven-month period leading up to the RWCS event, the Programmatic Initiatives workgroup convened virtually in the Wellness Think Tank, an online, resident community consisting of 142 residents from 100 EM residencies in North America. A 15-person subgroup (13 residents, two faculty facilitators) met at the RWCS to develop a public, central repository of initiatives for programs, as well as tools to assist programs in identifying gaps in their overarching wellness programs. An online submission form and central database of wellness initiatives were created and accessible to the public. Wellness Think Tank members collected an initial 36 submissions for the database by the time of the RWCS event. Based on general workplace, needs-assessment tools on employee wellbeing and Kern's model for curriculum development, a resident-based needs-assessment survey and an implementation worksheet were created to assist residency programs in wellness program development. The Programmatic Initiatives workgroup from the resident-driven RWCS event created tools to assist EM residency programs in identifying existing initiatives and gaps in their wellness programs to meet the ACGME's expanded focus on resident wellbeing.

Reconstruction of complex facial defects using cervical expanded flap prefabricated by temporoparietal fascia flap. Complex facial defects are required to restore not only function but also aesthetic appearance, so it is vital challenge for plastic surgeons. Skin grafts and traditional flap transfer cannot meet the reconstructive requirements of color and texture with recipient. The purpose of this sturdy is to create an expanded prefabricated temporoparietal fascia flap to repair complex facial defects. Two patients suffered severe burns on the face underwent complex facial resurfacing with prefabricated cervical flap. The vasculature of prefabricated flap, including the superficial temporal vessel and surrounding fascia, was used as the vascular carrier. The temporoparietal fascia flap was sutured underneath the cervical subcutaneous tissue, and expansion was begun in postoperative 1 week. After 4 to 6 months of expansion, the expander was removed, facial scars were excised, and cervical prefabricated flap was elevated and transferred to repair the complex facial defects. Two complex facial defects were repaired successfully by prefabricated temporoparietal fascia flap, and prefabricated flaps survived completely. On account of donor site's skin was thinner and expanded too fast, 1 expanded skin flap was rupture during expansion, but necrosis was not occurred after the 2nd operation. Venous congestion was observed in 1 patient, but after dressing, flap necrosis was not happened. Donor site was closed primarily. Postoperative follow-up 6 months, the color, texture of prefabricated flap was well-matched with facial skin. This method of expanded prefabricated flap may provide a reliable solution to the complex facial resurfacing.

There is an increasing recognition that evolutionary processes play a key role in determining the dynamics of range expansion. Recent work demonstrates that neutral mutations arising near the edge of a range expansion sometimes surf on the expanding front leading them rather than that leads to reach much greater spatial distribution and frequency than expected in stationary populations. Here, we extend this work and examine the surfing behavior of nonneutral mutations. Using an individual-based coupled-map lattice model, we confirm that, regardless of its fitness effects, the probability of survival of a new mutation depends strongly upon where it arises in relation to the expanding wave front. We demonstrate that the surfing effect can lead to deleterious mutations reaching high densities at an expanding front, even when they have substantial negative effects on fitness. Additionally, we highlight that this surfing phenomenon can occur for mutations that impact reproductive rate (i.e., number of offspring produced) as well as mutations that modify juvenile competitive ability. We suggest that these effects are likely to have important consequences for rates of spread and the evolution of spatially expanding populations.

Screw expander for light duty diesel engines

NASA Technical Reports Server (NTRS)

1983-01-01

Preliminary selection and sizing of a positive displacement screw compressor-expander subsystem for a light-duty adiabatic diesel engine; development of a mathematical model to describe overall efficiencies for the screw compressor and expander; simulation of operation to establish overall efficiency for a range of design parameters and at given engine operating points; simulation to establish potential net power output at light-duty diesel operating points; analytical determination of mass moments of inertia for the rotors and inertia of the compressor-expander subsystem; and preparation of engineering layout drawings of the compressor and expander are discussed. As a result of this work, it was concluded that the screw compressor and expander designed for light-duty diesel engine applications are viable alternatives to turbo-compound systems, with acceptable efficiencies for both units, and only a moderate effect on the transient response.

The Advanced Expander Test Bed (AETB) is a key element in NASA's Space Chemical Engine Technology Program for development and demonstration of expander cycle oxygen/hydrogen engine and advanced component technologies applicable to space engines as well as launch vehicle upper stage engines. The AETB will be used to validate the high-pressure expander cycle concept, investigate system interactions, and conduct investigations of advanced mission focused components and new health monitoring techniques in an engine system environment. The split expander cycle AETB will operate at combustion chamber pressures up to 1200 psia with propellant flow rates equivalent to 20,000 lbf vacuum thrust. Contract work began 27 Apr. 1990. During 1992, a major milestone was achieved with the review of the final design of the oxidizer turbopump in Sep. 1992.

Central Idaho has superior environmental amenities, as evidenced by exceptionally high-value tourism, such as guided whitewater rafting. The focus of our study concerns the attainment of high-quality jobs in a high-quality natural environment. We estimate cumulative wage rate effects unique to nonconsumptive river recreation in central Idaho for comparison with other sectors. The cumulative effects are based on a detailed survey of recreation spending and a modified synthesized input–output model. Cumulative wage rate effects support using the abundance of environmental amenities to expand and attract high-wage, environmentally sensitive firms, as opposed to expanded tourism to improve employment quality.
