  1. Starting a sleep center. (United States)

    Epstein, Lawrence J; Valentine, Paul S


    The demand for sleep medicine services has grown tremendously during the last decade and will likely continue. To date, growth in demand has been met by growth in the number of new sleep centers. The need for more new centers will be dependent on market drivers that include increasing regulatory requirements, personnel shortages, integration of home sleep testing, changes in reimbursement, a shift in emphasis from diagnostics to treatment, and an increased consumer focus on sleep. The decision to open a new center should be based on understanding the market dynamics, completing a market analysis, and developing a business plan. The business plan should include an overview of the facility, a personnel and organizational structure, an evaluation of the business environment, a financial plan, a description of services provided, and a strategy for obtaining, managing, and extending a referral base. Implementation of the business plan and successful operation require ongoing planning and monitoring of operational parameters. The need for new sleep centers will likely continue, but the shifting market dynamics indicate a greater need for understanding the marketplace and careful planning.

  2. The Research Role of a National Center. (United States)

    Silberman, Harry F.

    The functional role of a national center for vocational education depends on the people doing the work; consequently, the center sets its own agenda when it makes personal decisions. A center's role should include two elements: in setting its own research agenda, a center should take a broad perspective on vocational education; and a center should…

  4. A center open to the public (United States)

    Cuesta, L.; Vaquerizo, A.; García-Villadangos, M.


    The view to the public of a research center depends, of course, on the quality of its scientific activity but also, to a large extent, on the communication of results and spreading from the center itself. The Center for Astrobiology (CAB, CSIC-INTA) has maintained for some years a place among the leading Spanish scientific centers and the proof is his continued appearance in the media. In this communication we will give an overview of the activities of the Unit for Scientific Culture of CAB to achieve that goal.

  7. NYIT Energy Information Center. A first report

    Energy Technology Data Exchange (ETDEWEB)

    Magat, G.


    The Energy Information Center was created to serve (1) the research and information dissemination purposes of the Center for Energy Policy and Reearch, and (2) the information outreach programs of the Energy Advisory Service established by the Center. The Center is primarily concerned with (a) energy conservation, (b) alternative energy sources, (c) energy usage, and (d) energy policy, and insofar as they relate to these matters, it is concerned secondarily with fossil energy, nuclear energy, and international energy developments. Accordingly, the Energy Information Center acquires materials in such fields as engineering, economics, and the political, social, and behavioral sciences. In addition to serving the research and information dissemination needs of the Center for Energy Policy and Research, the Energy Information Center also supports the Center's Energy Advisory Service outreach program in which information and technical assistance in the use of energy conserving techniques and equipment is made available to industrial and commercial organizations, public officials, homeowners, and the general public throughout the New York New Jersey, and Connecticut area.

  9. Operating and Managing a Backup Control Center (United States)

    Marsh, Angela L.; Pirani, Joseph L.; Bornas, Nicholas


    Due to the criticality of continuous mission operations, some control centers must plan for alternate locations in the event an emergency shuts down the primary control center. Johnson Space Center (JSC) in Houston, Texas is the Mission Control Center (MCC) for the International Space Station (ISS). Due to Houston s proximity to the Gulf of Mexico, JSC is prone to threats from hurricanes which could cause flooding, wind damage, and electrical outages to the buildings supporting the MCC. Marshall Space Flight Center (MSFC) has the capability to be the Backup Control Center for the ISS if the situation is needed. While the MSFC Huntsville Operations Support Center (HOSC) does house the BCC, the prime customer and operator of the ISS is still the JSC flight operations team. To satisfy the customer and maintain continuous mission operations, the BCC has critical infrastructure that hosts ISS ground systems and flight operations equipment that mirrors the prime mission control facility. However, a complete duplicate of Mission Control Center in another remote location is very expensive to recreate. The HOSC has infrastructure and services that MCC utilized for its backup control center to reduce the costs of a somewhat redundant service. While labor talents are equivalent, experiences are not. Certain operations are maintained in a redundant mode, while others are simply maintained as single string with adequate sparing levels of equipment. Personnel at the BCC facility must be trained and certified to an adequate level on primary MCC systems. Negotiations with the customer were done to match requirements with existing capabilities, and to prioritize resources for appropriate level of service. Because some of these systems are shared, an activation of the backup control center will cause a suspension of scheduled HOSC activities that may share resources needed by the BCC. For example, the MCC is monitoring a hurricane in the Gulf of Mexico. As the threat to MCC

    We describe a population of small, high-velocity, atomic hydrogen clouds, loops, and filaments found above and below the disk near the Galactic center. The objects have a mean radius of 15 pc, velocity widths of {approx}14 km s{sup -1}, and are observed at |z| heights up to 700 pc. The velocity distribution of the clouds shows no signature of Galactic rotation. We propose a scenario where the clouds are associated with an outflow from a central star-forming region at the Galactic center. We discuss the clouds as entrained material traveling at {approx}200 km s{sup -1} in a Galactic wind.

  11. Donor Centers in a Gaussian Potential

    Institute of Scientific and Technical Information of China (English)

    XIE Wen-Fang


    We study a neutral donor center (D0) and a negatively charged donor center (D-) trapped by a quantum dot, which is subjected to a Gaussian potential confinement. Calculations are made by using the method of numerical diagonalization of Hamiltonian within the effective-mass approximation. The dependence of the ground state of the neutral shallow donor and the negatively charged donor on the dot size and the potential depth is investigated. The same calculations performed with the parabolic approximation of the Gaussian potential lead to the results that are qualitatively and quantitatively different from each other.

  12. A national neurological excellence centers network. (United States)

    Pazzi, S; Cristiani, P; Cavallini, A


    The most relevant problems related to the management of neurological disorders are (i) the frequent hospitalization in nonspecialist departments, with the need for neurological consultation, and (ii) the frequent requests of GPs for highly specialized investigations that are very expensive and of little value in arriving at a correct diagnosis. In 1996, the Consorzio di Bioingegneria e Informatica Medica in Italy realized the CISNet project (in collaboration with the Consorzio Istituti Scientifici Neuroscienze e Tecnologie Biomediche and funded by the Centro Studi of the National Public Health Council) for the implementation of a national neurological excellence centers network (CISNet). In the CISNet project, neurologists will be able to give on-line interactive consultation and off-line consulting services identifying correct diagnostic/therapeutic procedures, evaluating the need for both examination in specialist centers and admission to specialized centers, and identifying the most appropriate ones.

These photos were taken in a rehabilitation center in a small town in Gansu Province in the northwestern part of China.

  14. A Computer Learning Center for Environmental Sciences (United States)

    Mustard, John F.


    In the fall of 1998, MacMillan Hall opened at Brown University to students. In MacMillan Hall was the new Computer Learning Center, since named the EarthLab which was outfitted with high-end workstations and peripherals primarily focused on the use of remotely sensed and other spatial data in the environmental sciences. The NASA grant we received as part of the "Centers of Excellence in Applications of Remote Sensing to Regional and Global Integrated Environmental Assessments" was the primary source of funds to outfit this learning and research center. Since opening, we have expanded the range of learning and research opportunities and integrated a cross-campus network of disciplines who have come together to learn and use spatial data of all kinds. The EarthLab also forms a core of undergraduate, graduate, and faculty research on environmental problems that draw upon the unique perspective of remotely sensed data. Over the last two years, the Earthlab has been a center for research on the environmental impact of water resource use in and regions, impact of the green revolution on forest cover in India, the design of forest preserves in Vietnam, and detailed assessments of the utility of thermal and hyperspectral data for water quality analysis. It has also been used extensively for local environmental activities, in particular studies on the impact of lead on the health of urban children in Rhode Island. Finally, the EarthLab has also served as a key educational and analysis center for activities related to the Brown University Affiliated Research Center that is devoted to transferring university research to the private sector.

  2. A Student-Centered Learning Model

    Directory of Open Access Journals (Sweden)

    Mihyar Hesson


    Full Text Available Based on the authors experience in applying different approaches of active learning and student-centered teaching, the main problem that prevented the achievement of the full advantages of these approaches is the lack of motivation of students for self-centered learning. A new model for a student-centered learning is presented in this work. This model is of teaching integrative thinking, based on existing models of creativity and synthesis. In this model, the student is put at the heart of a bigger learning process that includes instructors, specialists and the public. Usually students who are in the final year of their study will be the target of the application of this model as a part of a capstone course or final year project. This model promotes the research and thinking skills of the students as well as the gained motivation of self-learning as a result of being in contact with the specialists who might be their potential future employers. A proto-type web-based system based on this model was developed. Although it is applied on a sample of students from the Biology department, the system is readily expandable to any number of other disciplines without any complications or programming overheads. The results achieved from the application of this model were very encouraging.

  4. [Problems of reception in a guidance center]. (United States)

    Mattelaer, P


    The aim of this communication is not to criticise the work of guidance, but to analyse its efficiency and validity in order to formulate concrete proposals. One can distinguish three periods in the evolution of the work in a guidance center. In the first period, it is a methodological concern which presided to this type of work. In the second period, one thought that there was to many preliminary investigations and it was decided to take the child in treatment more rapidly. During the third period, the attention has primarily be centered on the child's problems. The author suggests some solutions. He considers it is necessary to abandon the multidisciplinary approach. He advises to always consider one case at the time within a therapeutic and diagnostic frame. Therapy has to be conducted by one person, even if this person has to treat the whole family.

  5. Validation: A Family-Centered Communication Skill. (United States)

    Harvey, Pat; Ahmann, Elizabeth


    Family-centered care can seem challenging when family member behavior, choices, attitudes, or emotions are "difficult" or "challenging" to deal with. Yet nurses can develop skills to effectively interact with families in a wide variety of circumstances and then become able to practice family-centered care in any situation that might arise. One particularly useful skill is "validation," which means accepting what the family member says or does as a valid expression of thoughts and feelings in that particular circumstance at that particular time. Validation does not mean there is agreement or acceptance of unsafe behaviors, only that the nurse acknowledges that the family member's concerns and feelings are important and should be listened to and taken seriously, even in the presence of disagreement. Validation, which should be individualized, can take many forms, ranging from providing complete attention to reflection of statements, identification of possible unexpressed emotions, normalization, and finally, a full and genuine sense of connection. Understanding and practicing validation can empower nurses and family members, as well as support effectivefamily-centered communication and problem solving even in challenging circumstances.

  6. Transplant nephrectomy - A single-center experience

    Directory of Open Access Journals (Sweden)

    Arun Ariyarathenam


    Full Text Available Transplant nephrectomy (TN is associated with significant morbidity and mortality and influences the outcome of subsequent renal transplantation. The aim of this study was to identify the reasons for TN in a single transplant center in the United Kingdom and to determine the complication rate, effect on relisting and re-transplantation. We studied all the TNs in our center from January 2000 to December 2011. Detailed information including cause of allograft failure and reason for TN were analyzed. Of 602 renal transplants performed at our center during the period of the study, 42 TNs were performed on 38 (6% patients (24 men and 14 women. The median age of the patients at the time of transplantation who subsequently underwent TN was 56 years (range: 28-73 years and 71% of the allografts were donated after circulatory death. The mean human leucocyte antigen mismatch for these patients was 2.3. The most commonly used immunosuppression was a combination of prednisolone, mycophenolate and tacrolimus, which was used in 50% of the patients. Twenty-five (60% of the TNs in this series were for allografts failing during the first month of transplantation. The most common indication for the TN was graft thrombosis (50%, with an overall in-hospital mortality rate of 9.5% and a morbidity rate of 31%. Seven of 19 patients listed underwent successful re-transplantation. Although TN is associated with a risk of significant morbidity and mortality, it does not preclude from listing for re-transplantation. The difficulty of access to complete information about transplant failures and TN highlights the need for a national registry.

  8. A New Galactic Center Composite Supernova Remnant? (United States)

    Denn, G. R.; Hyman, S. D.; Lazio, T. J. W.; Kassim, N. E.


    We report the possible radio detection of a new supernova remnant located only 1 degree east of the Galactic center. The SNR candidate has both a shell and a core component on 6, 20, and 90 cm VLA images. Preliminary measurements indicate that both components have steep spectra between 6 and 20 cm, and that the spectra flatten and become inverted between 20 and 90 cm, due likely to significant free-free absorption. The source may be a composite-type SNR, which constitute only 10% of known SNRS, and which consist of a steep-spectrum radio shell corresponding to expanding debris from the supernova and a flatter spectrum, significantly polarized, core component corresponding to a central neutron star. Further radio and X-ray observations are planned in order to definitively identify this source. The detection of additional SNRs in or near the Galactic center will help place constraints on the star formation rate in this region, and may also provide clues about the GC environment. This research is supported by funding from the Sweet Briar College Faculty Grants program. Basic research in radio astronomy at NRL is supported by the Office of Naval Research.

  9. Establishment of a world food preservation center

    Directory of Open Access Journals (Sweden)

    Wilson Charles L


    Full Text Available Abstract A World Food Preservation Center (WFPC is proposed in response to a pending civilization-threatening food shortage and our limited ability to adequately increase food production. Some estimates put losses of food in developing countries after it is produced and before it is consumed at 50%. These losses are particularly threatening to individuals and farmers who are living in the midst of food insecurity. Although numerous organizations have attempted to address this problem worldwide, the magnitude of the effort has not come close to the enormity of the problem. Most of these programs are also short-term and require continuous input by postharvest specialists from developed countries in order to be sustainable. A critical need exists for a substantial and sustainable worldwide program that can significantly reduce losses and waste of food in developing countries. The World Food Preservation Center proposed here meets this need by educating young scientists in developing countries about low-input, appropriate technologies for preserving food postharvest. It also conducts research on postharvest technologies especially suited for application in developing countries such as biological control, solar refrigeration, and coordinated transport and marketing schemes that support and sustain the local production of food commodities.

  10. A Virtual Mission Operations Center: Collaborative Environment (United States)

    Medina, Barbara; Bussman, Marie; Obenschain, Arthur F. (Technical Monitor)


    The Virtual Mission Operations Center - Collaborative Environment (VMOC-CE) intent is to have a central access point for all the resources used in a collaborative mission operations environment to assist mission operators in communicating on-site and off-site in the investigation and resolution of anomalies. It is a framework that as a minimum incorporates online chat, realtime file sharing and remote application sharing components in one central location. The use of a collaborative environment in mission operations opens up the possibilities for a central framework for other project members to access and interact with mission operations staff remotely. The goal of the Virtual Mission Operations Center (VMOC) Project is to identify, develop, and infuse technology to enable mission control by on-call personnel in geographically dispersed locations. In order to achieve this goal, the following capabilities are needed: Autonomous mission control systems Automated systems to contact on-call personnel Synthesis and presentation of mission control status and history information Desktop tools for data and situation analysis Secure mechanism for remote collaboration commanding Collaborative environment for remote cooperative work The VMOC-CE is a collaborative environment that facilitates remote cooperative work. It is an application instance of the Virtual System Design Environment (VSDE), developed by NASA Goddard Space Flight Center's (GSFC) Systems Engineering Services & Advanced Concepts (SESAC) Branch. The VSDE is a web-based portal that includes a knowledge repository and collaborative environment to serve science and engineering teams in product development. It is a "one stop shop" for product design, providing users real-time access to product development data, engineering and management tools, and relevant design specifications and resources through the Internet. The initial focus of the VSDE has been to serve teams working in the early portion of the system

  13. Implementing the Data Center Energy Productivity Metric in a High Performance Computing Data Center

    Energy Technology Data Exchange (ETDEWEB)

    Sego, Landon H.; Marquez, Andres; Rawson, Andrew; Cader, Tahir; Fox, Kevin M.; Gustafson, William I.; Mundy, Christopher J.


    As data centers proliferate in size and number, the improvement of their energy efficiency and productivity has become an economic and environmental imperative. Making these improvements requires metrics that are robust, interpretable, and practical. We discuss the properties of a number of the proposed metrics of energy efficiency and productivity. In particular, we focus on the Data Center Energy Productivity (DCeP) metric, which is the ratio of useful work produced by the data center to the energy consumed performing that work. We describe our approach for using DCeP as the principal outcome of a designed experiment using a highly instrumented, high-performance computing data center. We found that DCeP was successful in clearly distinguishing different operational states in the data center, thereby validating its utility as a metric for identifying configurations of hardware and software that would improve energy productivity. We also discuss some of the challenges and benefits associated with implementing the DCeP metric, and we examine the efficacy of the metric in making comparisons within a data center and between data centers.

  14. Hanford Nuclear Energy Center: a conceptual study

    Energy Technology Data Exchange (ETDEWEB)

    Harty, H. (comp.)


    The objective of the study is to develop an improved understanding of the nuclear energy center (NEC) concept and to identify research and development needed to evaluate the concept fully. A specific context was selected for the study--the Hanford site. Thus, the study primarily addresses the HNEC concept, but the findings are extrapolated to generic NECs where possible. The major emphasis in the HNEC study was to explore potential technical and environmental problems in a specific context and in sufficient detail to evaluate potential problems and propose practical solutions. The areas of concern are typical of those considered in preparing environmental and safety analysis reports, including: topics dealing with engineering choices (e.g., site selection, heat sink management, electrical transmission, and reliability of generation); environmental matters (e.g., terrestrial and radiological effects); socioeconomic factors (e.g., community impacts); and licensing considerations.

  16. To center or not to center? Investigating inertia with a multilevel autoregressive model

    Directory of Open Access Journals (Sweden)

    Ellen L. Hamaker


    Full Text Available Whether level 1 predictors should be centered per cluster has received considerable attention in the multilevel literature. While most agree that there is no one preferred approach, it has also been argued that cluster mean centering is desirable when the within-cluster slope and the between-cluster slope are expected to deviate, and the main interest is in the within-cluster slope. However, we show in a series of simulations that if one has a multilevel autoregressive model in which the level 1 predictor is the lagged outcome variable (i.e., the outcome variable at the previous occasion, cluster mean centering will in general lead to a downward bias in the parameter estimate of the within-cluster slope (i.e., the autoregressive relationship. This is particularly relevant if the main question is whether there is on average an autoregressive effect. Nonetheless, we show that if the main interest is in estimating the effect of a level 2 predictor on the autoregressive parameter (i.e., a cross-level interaction, cluster mean centering should be preferred over other forms of centering. Hence, researchers should be clear on what is considered the main goal of their study, and base their choice of centering method on this when using a multilevel autoregressive model.

  18. Pregnancy during Hemodialysis: A Single Center Experience

    Directory of Open Access Journals (Sweden)

    Bahadi Abdelali


    Full Text Available Successful pregnancy outcome is an uncommon occurrence in women requiring chronic dialysis treatment. We reviewed the course and outcome of 9 pregnancies occurred in women on chronic hemodialysis in our center from 1999-2007; 5 of them ended with delivery of alive newborns, 2 with fetal deaths in-utero, and 2 with abortions. The average age of patients was 34 years. The etiology of the original kidney disease was unknown in 44.4% of the cases, and only 22.2% of the patients maintained diuresis. Dialysis started in 8 cases before the diagnosis of pregnancy. The average gestational age at diagnosis was 14 weeks. We modified the prescription of dialysis in 4 patients by increasing the frequency of the dialysis sessions to 6 per week and in 3 by increasing the duration of each session to 6 hours. Anemia was present in all the cases; 3 patients received erythropoietin and 4 patients required transfusion. The pregnancy was com-plicated in 44% of the cases by a polyhydramnios. The average time at delivery was 33 weeks and it was achieved in 80% of pregnancies through vaginal route. The average weight of newborns was to 2380 g. We conclude that pregnancy in women on hemodialysis is possible. The success of pregnancy may be influenced by the residual diuresis and early diagnosis to improve the quality of dialysis by increasing the dialysis dose.

  19. So You Want to Start a Peer Online Writing Center?

    Directory of Open Access Journals (Sweden)

    Christine Rosalia


    Full Text Available The purpose of this article is to share lessons learned in setting up three different peer online writing centers in three different contexts (EFL, Generation 1.5, and ESL. In each center the focus was on the language learner as a peer online writing advisor and their needs in maintaining centers “for and by” learners. Technology affordances and constraints for local contexts, which promote learner autonomy, are analyzed. The open-source platforms (Moodle, Drupal, and Google Apps are compared in terms of usability for peer writing center work, particularly centers where groups co-construct feedback for writers, asynchronously. This paper is useful for readers who would like a head start or deeper understanding of potential logistics and decision-making involved in establishing a peer online writing center within coursework and/or a self-access learning center.

STAI I and II data were used for proceeding to the level of anxiety of patients before and/or after the operation. Results: Sixty consecutive patients, with a mean age of 40.6 ± 8.1 years underwent ALC. Fifty-five (92% patients could be sent to their homes on the same day but five patients could not be sent due to anxiety, pain, or social indications. Nausea was reported in four (6.7% cases and not associated with any demographic or clinical features of patients. On the other hand, pain has been reported in 28 (46.7% cases, and obesity and shorter duration of gallbladder disease were associated with the increased pain perception (P = 0.009 and 0.004, respectively. Preopereative anxiety level was significantly higher among patients who could not complete the ALC procedure (P = 0.018. Conclusion: Correct management of these possible adverse effects results in the increased satisfaction of patients and may encourage this more cost-effective and safe method of laparoscopic cholecystectomy.

  3. Moving Online: Changing the Focus of a Writing Center

    Directory of Open Access Journals (Sweden)

    Gene Thompson


    Full Text Available This paper charts the development of a small departmental writing center at a university in Japan. The paper discusses the results from two semesters of an ongoing action research project focused on improving the usage of the center. Faced with significant constraints and decreasing usage, the project used student survey data collected at the end of each semester to drive developments to the center. This led to a shift from using a face-to-face peer model for the writing center, to organizing it as an online writing lab. The article demonstrates the potential benefits of moving online for centers facing significant constraints, and the importance of using data for decision making in driving center development.

However, with the increasing rate of drug abuse in coastal

  7. Analyzing the teaching style of nursing faculty. Does it promote a student-centered or teacher-centered learning environment? (United States)

    Schaefer, Karen Moore; Zygmont, Dolores


    The purposes of this study were to a) describe the predominant teaching style of a group of nursing faculty members, either as teacher centered or student centered, and b) to compare teaching style to the instructional methods the faculty members used in the courses they taught and to their stated philosophies of teaching/learning. Findings indicate that the participants were more teacher centered than student centered; their written philosophies supported the teacher-centered approach. However, evidence that faculty used student-centered language, often in a teacher-centered context, indicates that participants in the study may recognize the need for a student-centered environment but may have difficulty with implementation. Recommendations for faculty members and administrators are offered.

  11. Pediatric renal transplantation: a single center experience

    Directory of Open Access Journals (Sweden)

    João Nascimento


    Full Text Available Introduction: End-stage renal disease in children is associated with numerous comorbidities and with age-specific mortality rates approximately 30 times higher than in healthy children. The first kidney transplantation in children was performed successfully in 1954. Surgical advances and new immunosuppressive medications have greatly improved patient’s and graft’s survival in the last years. Aim: Report Centro Hospitalar do Porto experience in pediatric renal transplantation in the last 30 years. Methods: Epidemiological and clinical data of all patients younger than 18 years, transplanted between January 1984 and August 2013, were collected from our database. In order to analyze the transplantation outcome in our center we compare graft survival between decades (1984-89 / 1990-99 / 2000-09 / 2010-13. We also compare graft survival between two age groups of patients (0-10 years ; 11-17 years at the time of surgery. Results: One hundred thirty-nine patients (58.3% male underwent 147 renal transplants (6.8% live donors. Congenital anomalies of the kidney and urinary tract (56.5% and glomerulonephritis (18.4% were the major causes of renal disease. Uncensored graft survivals rates at 5, 10, 15 and 20 years were 84.7%, 71.1%, 60.0% and 51.0%, while patient survivals were 97.9%, 95.9%, 94.7% and 94.7% respectively. Graft survival improved over time and the difference between the decades was statistically significant (p=0.004. Despite the better survival in the group of patients older than 11 years, graft’s survival difference between the two age groups was not statistically significant (p=0.697. Conclusion: The results of our hospital are comparable to other international centers. Significant improvement in survival was observed over the time. It seems that an accurate follow-up of our patients helps to minimize the negative impact of adolescence on graft survival rates.

  13. Efficacy of primary care in a nursing center. (United States)

    Helvie, C O


    Nursing opportunities have expanded beyond the traditional bedside role. Nurses serve in a variety of roles such as administrators, teachers, or primary care givers in a variety of settings. The role of primary care giver is a more recent role; it involves relatively independent nursing practice with clients who have acute or chronic illnesses. Client groups may include the elderly in high rise buildings, mothers and children at schools, or homeless and low-income populations at homeless shelters. This care is often provided in a nursing center. Nursing centers are nurse-managed centers in which nurses are accountable and responsible for care of clients; they are the primary provider of care and the one most seen by clients. Case managers may be in a position to refer patients to nursing centers or to work directly with nurse practitioners in nursing centers. However, questions about the primary care provided in nursing centers must be addressed for healthcare providers, insurance companies, and patients to be confident in the efficacy of this delivery system. Is the primary care comprehensive? Is it of high quality? Is it cost effective? Is it satisfactory to clients? These and other questions about the primary care provided in nursing centers must be answered to effect political and other changes needed to fulfill the role of nursing centers envisioned by early leaders of the movement. This article addresses questions related to the efficacy of primary care provided in nursing centers by family nurse practitioners. After defining efficacy, the discussion focuses on the components identified and studied in one nursing center and includes information on opportunities for case managers to utilize nursing centers for referral and appropriate follow-up of their patients.

  3. Child center closures: Does nonprofit status provide a comparative advantage? (United States)

    Lam, Marcus; Klein, Sacha; Freisthler, Bridget; Weiss, Robert E


    Reliable access to dependable, high quality childcare services is a vital concern for large numbers of American families. The childcare industry consists of private nonprofit, private for-profit, and governmental providers that differ along many dimensions, including quality, clientele served, and organizational stability. Nonprofit providers are theorized to provide higher quality services given comparative tax advantages, higher levels of consumer trust, and management by mission driven entrepreneurs. This study examines the influence of ownership structure, defined as nonprofit, for-profit sole proprietors, for-profit companies, and governmental centers, on organizational instability, defined as childcare center closures. Using a cross sectional data set of 15724 childcare licenses in California for 2007, we model the predicted closures of childcare centers as a function of ownership structure as well as center age and capacity. Findings indicate that for small centers (capacity of 30 or less) nonprofits are more likely to close, but for larger centers (capacity 30+) nonprofits are less likely to close. This suggests that the comparative advantages available for nonprofit organizations may be better utilized by larger centers than by small centers. We consider the implications of our findings for parents, practitioners, and social policy.

  6. Development and assessment of a biotechnology workforce development center model (United States)

    Huxley, Mary Pat

    Life science and biotechnology companies are the fastest growing industries in the nation, with more than 30% of these companies and close to 50% of the nation's life science workers located in California. The need for well-trained biotechnology workers continues to grow. Educational institutions and industry professionals have attempted to create the training and the workforce for the bioscience and biotechnology industry. Many have concluded that one way would be to create a multiuse training center where trainees from high school age through late adulthood could receive up-to-date training. This case study had 2 unique phases. Phase 1 consisted of examining representative stakeholder interview data for characteristics of an ideal biotechnology shared-use regional education (B-SURE) center, which served as the basis for an assessment tool, with 107 characteristics in 8 categories. This represented what an ideal center model should include. Phase 2 consisted of using this assessment tool to gather data from 6 current biotechnology regional centers to determine how these centers compared to the ideal model. Results indicated that each center was unique. Although no center met all ideal model characteristics, the 6 centers could clearly be ranked. Recommendations include refining the core characteristics, further assessing the existing and planned centers; evaluating and refining the interview instrument in Phase 1 and the assessment tool in Phase 2 by including additional stakeholders in both phases and by adding reviewers of Phase 1 transcripts; and determining a method to demonstrate a clear return on investment in a B-SURE center.

  7. Nanoscale fluorescence lifetime imaging with a single diamond NV center

    CERN Document Server

    Beams, Ryan; Johnson, Timothy W; Oh, Sang-Hyun; Novotny, Lukas; Vamivakas, Nick


    Solid-state quantum emitters, such as artificially engineered quantum dots or naturally occurring defects in solids, are being investigated for applications ranging from quantum information science and optoelectronics to biomedical imaging. Recently, these same systems have also been studied from the perspective of nanoscale metrology. In this letter we study the near-field optical properties of a diamond nanocrystal hosting a single nitrogen vacancy center. We find that the nitrogen vacancy center is a sensitive probe of the surrounding electromagnetic mode structure. We exploit this sensitivity to demonstrate nanoscale fluorescence lifetime imaging microscopy (FLIM) with a single nitrogen vacancy center by imaging the local density of states of an optical antenna.

  8. A possible role of chemotaxis in germinal center formation

    CERN Document Server

    Beyer, T; Soff, G; Beyer, Tilo; Meyer-Hermann, Michael; Soff, Gerhard


    During the germinal center reaction a characteristic morphology is developed. In the framework of a recently developed space-time-model for the germinal center a mechanism for the formation of dark and light zones has been proposed. The mechanism is based on a diffusing differentiation signal which is secerned by follicular dendritic cells. Here, we investigate a possible influence of recently found chemokines for the germinal center formation in the framework of a single-cell-based stochastic and discrete three-dimensional model. We will also consider alternative possible chemotactic pathways that may play a role for the development of both zones. Our results suggest that the centrocyte motility resulting from a follicular dendritic cell-derived chemokine has to exceed a lower limit to allow the separation of centroblasts and centrocytes. In contrast to light microscopy the dark zone is ring shaped. This suggests that FDC-derived chemoattractants alone cannot explain the typical germinal center morphology.

  11. The Universe Observing Center a modern center to teach and communicate astronomy (United States)

    Ribas, Salvador J.


    The Universe Observing Center is one of the parts of the Parc Astronòmic Montsec (PAM). PAM is an initiative of the Catalan government, through the Consorci del Montsec (Montsec Consortium), to take advantage of the capabilities and potential of the Montsec region to develop scientific research, training and outreach activities, particularly in the field of Astronomy. The choice of the Montsec mountains to install the PAM was motivated by the magnificent conditions for observing the sky at night; the sky above Montsec is the best (natural sky free of light pollution) in Catalonia for astronomical observations. The PAM has two main parts: the Observatori Astronòmic del Montsec (OAdM) and the Universe Observing Center (COU). The OAdM is a professional observatory with an 80-cm catadioptric telescope (Joan Oró Telescope). This telescope is a robotic telescope that can be controlled from anywhere in the world via the Internet. The COU is a large multipurpose center which is intended to become an educational benchmark for teaching and communicate astronomy and other sciences in Catalonia. The management of the COU has three main goals: 1) Teach primary and secondary school students in our Educational Training Camp. 2) Teach university students housing the practical astronomy lectures of the universities. 3) Communicate astronomy to the general public. The COU comprises special areas for these purposes: the Telescopes Park with more than 20 telescopes, a coelostat for solar observations and two dome containing full-automated telescopes. The most special equipment is ``The Eye of Montsec'', with its 12m dome containing a multimedia digital planetarium and a platform for direct observation of the sky and the environment. During 2009 we expect around 10000 visitors in Montsec area to enjoy science with Montsec dark skies and an special natural environment.

  12. Implementing a Reliability Centered Maintenance Program at NASA's Kennedy Space Center (United States)

    Tuttle, Raymond E.; Pete, Robert R.


    Maintenance practices have long focused on time based "preventive maintenance" techniques. Components were changed out and parts replaced based on how long they had been in place instead of what condition they were in. A reliability centered maintenance (RCM) program seeks to offer equal or greater reliability at decreased cost by insuring only applicable, effective maintenance is performed and by in large part replacing time based maintenance with condition based maintenance. A significant portion of this program involved introducing non-intrusive technologies, such as vibration analysis, oil analysis and I/R cameras, to an existing labor force and management team.

  16. A Dynamic and Interactive Monitoring System of Data Center Resources

    Directory of Open Access Journals (Sweden)

    Yu Ling-Fei


    Full Text Available To maximize the utilization and effectiveness of resources, it is very necessary to have a well suited management system for modern data centers. Traditional approaches to resource provisioning and service requests have proven to be ill suited for virtualization and cloud computing. The manual handoffs between technology teams were also highly inefficient and poorly documented. In this paper, a dynamic and interactive monitoring system for data center resources, ResourceView, is presented. By consolidating all data center management functionality into a single interface, ResourceView shares a common view of the timeline metric status, while providing comprehensive, centralized monitoring of data center physical and virtual IT assets including power, cooling, physical space and VMs, so that to improve availability and efficiency. In addition, servers and VMs can be monitored from several viewpoints such as clusters, racks and projects, which is very convenient for users.

  1. Human-centered design of a distributed knowledge management system. (United States)

    Rinkus, Susan; Walji, Muhammad; Johnson-Throop, Kathy A; Malin, Jane T; Turley, James P; Smith, Jack W; Zhang, Jiajie


    Many healthcare technology projects fail due to the lack of consideration of human issues, such as workflow, organizational change, and usability, during the design and implementation stages of a project's development process. Even when human issues are considered, the consideration is typically on designing better user interfaces. We argue that human-centered computing goes beyond a better user interface: it should include considerations of users, functions and tasks that are fundamental to human-centered computing. From this perspective, we integrated a previously developed human-centered methodology with a Project Design Lifecycle, and we applied this integration in the design of a complex distributed knowledge management system for the Biomedical Engineer (BME) domain in the Mission Control Center at NASA Johnson Space Center. We analyzed this complex system, identified its problems, generated systems requirements, and provided specifications of a replacement prototype for effective organizational memory and knowledge management. We demonstrated the value provided by our human-centered approach and described the unique properties, structures, and processes discovered using this methodology and how they contributed in the design of the prototype.

  2. [A relational database to store Poison Centers calls]. (United States)

    Barelli, Alessandro; Biondi, Immacolata; Tafani, Chiara; Pellegrini, Aristide; Soave, Maurizio; Gaspari, Rita; Annetta, Maria Giuseppina


    Italian Poison Centers answer to approximately 100,000 calls per year. Potentially, this activity is a huge source of data for toxicovigilance and for syndromic surveillance. During the last decade, surveillance systems for early detection of outbreaks have drawn the attention of public health institutions due to the threat of terrorism and high-profile disease outbreaks. Poisoning surveillance needs the ongoing, systematic collection, analysis, interpretation, and dissemination of harmonised data about poisonings from all Poison Centers for use in public health action to reduce morbidity and mortality and to improve health. The entity-relationship model for a Poison Center relational database is extremely complex and not studied in detail. For this reason, not harmonised data collection happens among Italian Poison Centers. Entities are recognizable concepts, either concrete or abstract, such as patients and poisons, or events which have relevance to the database, such as calls. Connectivity and cardinality of relationships are complex as well. A one-to-many relationship exist between calls and patients: for one instance of entity calls, there are zero, one, or many instances of entity patients. At the same time, a one-to-many relationship exist between patients and poisons: for one instance of entity patients, there are zero, one, or many instances of entity poisons. This paper shows a relational model for a poison center database which allows the harmonised data collection of poison centers calls.

  4. A patient-centered care ethics analysis model for rehabilitation. (United States)

    Hunt, Matthew R; Ells, Carolyn


    There exists a paucity of ethics resources tailored to rehabilitation. To help fill this ethics resource gap, the authors developed an ethics analysis model specifically for use in rehabilitation care. The Patient-Centered Care Ethics Analysis Model for Rehabilitation is a process model to guide careful moral reasoning for particularly complex or challenging matters in rehabilitation. The Patient-Centered Care Ethics Analysis Model for Rehabilitation was developed over several iterations, with feedback at different stages from rehabilitation professionals and bioethics experts. Development of the model was explicitly informed by the theoretical grounding of patient-centered care and the context of rehabilitation, including the International Classification of Functioning, Disability and Health. Being patient centered, the model encourages (1) shared control of consultations, decisions about interventions, and management of the health problems with the patient and (2) understanding the patient as a whole person who has individual preferences situated within social contexts. Although the major process headings of the Patient-Centered Care Ethics Analysis Model for Rehabilitation resemble typical ethical decision-making and problem-solving models, the probes under those headings direct attention to considerations relevant to rehabilitation care. The Patient-Centered Care Ethics Analysis Model for Rehabilitation is a suitable tool for rehabilitation professionals to use (in real time, for retrospective review, and for training purposes) to help arrive at ethical outcomes.

  5. Defining the medical imaging requirements for a rural health center

    CERN Document Server


    This book establishes the criteria for the type of medical imaging services that should be made available to rural health centers, providing professional rural hospital managers with information that makes their work more effective and efficient. It also offers valuable insights into government, non-governmental and religious organizations involved in the planning, establishment and operation of medical facilities in rural areas. Rural health centers are established to prevent patients from being forced to travel to distant urban medical facilities. To manage patients properly, rural health centers should be part of regional and more complete systems of medical health care installations in the country on the basis of a referral and counter-referral program, and thus, they should have the infrastructure needed to transport patients to urban hospitals when they need more complex health care. The coordination of all the activities is only possible if rural health centers are led by strong and dedicated managers....

  11. Mathematica a problem-centered approach

    CERN Document Server

    Hazrat, Roozbeh


    This textbook introduces the vast array of features and powerful mathematical functions of Mathematica using a multitude of clearly presented examples and worked-out problems. Each section starts with a description of a new topic and some basic examples. The author then demonstrates the use of new commands through three categories of problems - the first category highlights those essential parts of the text that demonstrate the use of new commands in Mathematica whilst solving each problem presented; - the second comprises problems that further demonstrate the use of commands previously introduced to tackle different situations; and - the third presents more challenging problems for further study. The intention is to enable the reader to learn from the codes, thus avoiding long and exhausting explanations. While based on a computer algebra course taught to undergraduate students of mathematics, science, engineering and finance, the book also includes chapters on calculus and solving equations, and graphics, t...

    Sasi Kiran Attili


    Full Text Available Background: Ultraviolet A1(UVA1 phototherapy is increasingly being used in the treatment of morphea, atopic dermatitis, lupus and some other recalcitrant dermatoses. We present a retrospective review of our experience with this modality. Aim: To evaluate the treatment response rates for various dermatoses and adverse effects of UVA1 phototherapy. Methods: We reviewed phototherapy notes along with electronic and/or paper case records for all patients treated with UVA1 phototherapy from October 1996 to December 2008. Results: A total of 269 patients (outcomes available for 247 had 361 treatment courses (treatment data available for 317 courses over this period. We found phototherapy to be beneficial in 28 (53% of 53 patients with atopic dermatitis and 19 (51% of 37 patients with morphea. A beneficial outcome was recorded in all six (100% cases of urticaria and six (85.7% of seven patients treated for a polymorphic light eruption. Benefit was also recorded in systemic lupus erythematosus (8 (44.4% of 18, lichen sclerosus (6 (42.9% of 14, mastocytosis (2 (33.3% of 6, necrobiosis lipoidica (4 (30.8% of 13, granuloma annulare (2 (25% of 8, scleroderma (2 (22.2% of 9 and keloids (1 (7.7% of 13. Overall, treatment was well tolerated with no patients having to stop treatment due to adverse effects. Limitations: This is a retrospective study with no control group. Subjective/recall bias is quite possible as a number of patients were followed up over the phone. Conclusions: Our data suggest that ultraviolet A1 can be considered for the treatment of selected dermatoses. However, long-term malignancy risk is as yet unknown.

  13. Anatomy of a ubiquitous media center (United States)

    Serrano, Manuel


    lThe Web is such a rich architecture that it is giving birth to new applications that were unconceivable only few years ago in the past. Developing these applications being different from developing traditional applications, generalist programming languages are not well suited. To help face this problem, we have conceived the Hop programming language whose syntax and semantics are specially crafted for programming Web applications. In order to demonstrate that Hop, and its SDK, can be used for implementing realistic applications, we have started to develop new innovative applications that extensively relies on the infrastructure offered by Web and that use Hop unique features. We have initiated this effort with a focus on multimedia applications. Using Hop we have implemented a distributed audio system. It supports a flexible architecture that allows new devices to catch up with the application any time: a cell phone can be used to pump up the volume, a PDA can be used to browse over the available musical resources, a laptop can be used to select the output speakers, etc. This application is intrinsically complex to program because, i) it is distributed (several different devices access and control shared resources such a music repositories and sound card controllers), ii) it is dynamic (new devices may join or quit the application at any time), and iii) it involves different heterogeneous devices with different hardware architectures and different capabilities. In this paper, we present the two main Hop programming forms that allow programmers to develop multimedia applications more easily and we sketch the parts of the implementation of our distributed sound system that illustrate when and why Hop helps programming Web multimedia applications.

  14. [Intercommunication psychiatry in a burn center]. (United States)

    Ravella, P; Prallet, J P; Latarjet, J; Parizot, S; Bouchet, P


    The support of psychiatric disorders in a burn centre has been effected since three years, in Saint Luc Hospital (Lyon) thanks to a liaison group. One hour a week, several cases of patients are approached in this group which gathers two psychiatrists and the team dealing with burnt patients. Psychiatrists are attached to clarify the relation between people who attend and patients, to give a diagnosis and propose a strategy in front of difficulties they meet. The psychiatric care is reintegrated in the somatic support and assured by people who are daily effectively in contact with patients. This paper describes the advantages of the liaison psychiatry with regard to a direct intervention of the psychiatrist on the patient. It defines the targets these therapeutic weapon can aim and details the obtained results: for 3 years, the group has met 104 times for 241 "indirect consultations" concerning 99 different patients and count 50 good results on site and 5 specialized orientations; 10 deaths and 11 quick departures exclude 21 patients from the study; 17 cases have been stayed without continuation and 6 without any change.

    Full Text Available Management, above all, is the controlling element responsible for coordinating the three basic business functions; production, marketing, and finance.  Mechanisms exist to facilitate the finance function with influence coming from outside regulatory bodies such as the AICPA, IIA, SEC, and other regulators.  Integrating the finance function into organizations, then, becomes somewhat generic (although some would argue this point.  Coordinating the functions of marketing and production is a much more difficult endeavor because it lacks the standardization seen in finance.  This paper suggests employing a more user-focused approach as a means to improving the overall quality of products, and eventually, the success of the organization.  Specifically, this paper explores the role of the human brain in the calculus of choice, discusses the role of consumer involvement as it leads to product attachment, and offers suggestions for employing contextual research to improve product design and quality.

  16. Narrating narcolepsy--centering a side effect. (United States)

    Lundgren, Britta


    The mass-vaccination with Pandemrix was the most important preventive measure in Sweden during the A(H1N1) influenza pandemic of 2009-2010, and covered 60% of the population. From 2010, an increased incidence of the neurological disease narcolepsy was reported, and an association with Pandemrix was affirmed for more than 200 children and young adults. The parental experience of this side effect provided a starting point for a collectively shaped critical narrative to be acted out in public, but also personalized narratives of continual learning about the disease and its consequences. This didactic functionality resulted in active meaning-making practices about how to handle the aftermath--using dark humor, cognitive tricks, and making themselves and their children's bodies both objects and subjects of knowledge. Using material from interviews with parents, this mixing of knowledge work and political work, and the potential for reflective consciousness, is discussed.

    Full Text Available Materials and Methods: The study was performed on prospective donors who reported to the Department of Transfusion Medicine. Individuals deferred due to hypertension contributed the study population. They were compared with age and sex matched donor controls. Demographic details were recorded in a proforma. On identification of a hypertensive individual, consequent two comparable donors were taken as controls with a total of 50 hypertensive subjects. Hypertensive status of the subjects were assessed based on the criteria formulated by the WHO-ISH and US Seventh Joint National Committee report on prevention, detection, evaluation and treatment of high blood pressure. Results: About 0.95% of healthy blood donors had undetected hypertension. Mean age at detection of hypertension in the study group was 35.44 ± 7.69 years. Higher BMI was observed in the hypertensive group compared to normotensive control group with P value significant at 0.0001. Conclusion: About 1% of healthy individuals were found to have undetected hypertension. Though the study was not designed to determine the prevalence of hypertension in the region, it is a rough estimate of the proportion of undetected hypertension in the local population as donors are considered as representative of healthy population.

    Abdullah Oğuz


    Full Text Available Objective: Fecal diversion is often indicated in cases with fecal incontinence, Fournier’s gangrene, anal fistula, and inoperable obstructive anorectal cancer. Trephine colostomy can be performed without necessitating laparotomy. We present our experience related to the outcome of trephine sigmoid colostomy. Methods: The retrospective study included 14 patients who underwent trephine colostomy due to various conditions including Fournier’s gangrene, inoperable anorectal cancer, recto-vaginal fistula, and benign stricture due to radiotherapy at our clinic between January 2010 and January 2015. Results: Patients comprised 4 females and 10 males with a mean age of 52.07 years. The indications for stoma formation were Fournier’s gangrene in 7 cases, inoperable anorectal cancer in 5, rectovaginal fistula in 1, and benign stricture due to radiotherapy in 1 case. Eight patients underwent surgery under regional anesthesia. All the patients underwent trephine loop sigmoid colostomy. One patient had second operation on the postoperative period due to colostomy prolapse. The temporary stomas were closed in 3 months. Mean length of hospital stay was 14 days. Conclusion: Trephine stoma is a relatively simple, safe and rapid procedure and an effective alternative to colostomy formation without laparotomy indications. It can be performed under emergency or elective conditions with low morbidity. J Clin Exp Invest 2015; 6 (2: 87-90

  1. The National Center for Atmospheric Research (NCAR) Research Data Archive: a Data Education Center (United States)

    Peng, G. S.; Schuster, D.


    The National Center for Atmospheric Research (NCAR) Research Data Archive (RDA),, is not just another data center or data archive. It is a data education center. We not only serve data, we TEACH data. Weather and climate data is the original "Big Data" dataset and lessons learned while playing with weather data are applicable to a wide range of data investigations. Erroneous data assumptions are the Achilles heel of Big Data. It doesn't matter how much data you crunch if the data is not what you think it is. Each dataset archived at the RDA is assigned to a data specialist (DS) who curates the data. If a user has a question not answered in the dataset information web pages, they can call or email a skilled DS for further clarification. The RDA's diverse staff—with academic training in meteorology, oceanography, engineering (electrical, civil, ocean and database), mathematics, physics, chemistry and information science—means we likely have someone who "speaks your language." Data discovery is another difficult Big Data problem; one can only solve problems with data if one can find the right data. Metadata, both machine and human-generated, underpin the RDA data search tools. Users can quickly find datasets by name or dataset ID number. They can also perform a faceted search that successively narrows the options by user requirements or simply kick off an indexed search with a few words. Weather data formats can be difficult to read for non-expert users; it's usually packed in binary formats requiring specialized software and parameter names use specialized vocabularies. DSs create detailed information pages for each dataset and maintain lists of helpful software, documentation and links of information around the web. We further grow the level of sophistication of the users with tips, tutorials and data stories on the RDA Blog, How-to video tutorials are also posted on the NCAR Computational and Information Systems

    Energy Technology Data Exchange (ETDEWEB)

    Monti, Henri [Virginia Polytechnic Institute and State University (Virginia Tech); Butt, Ali R [Virginia Polytechnic Institute and State University (Virginia Tech); Vazhkudai, Sudharshan S [ORNL


    Modern High-Performance Computing applications are consuming and producing an exponentially increasing amount of data. This increase has lead to a significant number of resources being dedicated to data staging in and out of Supercomputing Centers. The typical approach to staging is a direct transfer of application data between the center and the application submission site. Such a direct data transfer approach becomes problematic, especially for staging-out, as (i) the data transfer time increases with the size of data, and may exceed the time allowed by the center's purge policies; and (ii) the submission site may not be online to receive the data, thus further increasing the chances for output data to be purged. In this paper, we argue for a systematic data staging-out approach that utilizes intermediary data-holding nodes to quickly offload data from the center to the intermediaries, thus avoiding the peril of a purge and addressing the two issues mentioned above. The intermediary nodes provide temporary data storage for the staged-out data and maximize the offload bandwidth by providing multiple data-flow paths from the center to the submission site. Our initial investigation shows such a technique to be effective in addressing the above two issues and providing better QOS guarantees for data retrieval.

  4. [Promoting research in a medical center--the management narrative]. (United States)

    Halevy, Jonathan; Turner, Dan


    Promoting research within a medical institute is a delicate balance between the importance of facilitating academia and maximizing resources towards the primary goal of a hospital--healing sick people. Shaare Zedek Medical Center have successfully adopted a "niche" approach to research in which the hospital invests in selected talented clinicians-scientists rather than futile expectation that all clinicians would be engaged in high impact research. Moreover, these research excellence centers are developing into a driving force to also foster research endeavors of other clinicians and residents in the hospital. In this special issue of Harefuah honoring Shaare Zedek investigators, 18 manuscripts included reflect the diversity of research projects performed in the medical center. We believe that this project will assist and encourage clinicians to be engaged in research, at all levels and disciplines.

  5. Towards a spin radar with Nitrogen Vacancy centers in diamond (United States)

    Ajoy, Ashok; Liu, Yixiang; Cappellaro, Paola


    Nitrogen Vacancy (NV) centers in diamond are a promising platform for nanoscale magnetic resonance imaging. The NV spin can be used to sense the presence of external nuclear spins, and through them biomolecule structure, by exploiting anisotropic hyperfine interactions. The NV center thus effectively acts as a dipole ``antenna'', detecting and identifying spins at different spatial locations. The antenna dipole is typically set by the diamond and target sample geometry, and nuclear spins are often found in the NV's dipole blind spot. In this work, we demonstrate an experimental technique by which one can controllably turn and manipulate the direction of this effective NV antenna over a wide range of approximately +-40 degrees. In combination with filtered back projection techniques, this method allows reconstructing with high resolution the real space position of spins in the NV center environment.

  7. Envisioning a Quantitative Studies Center: A Liberal Arts Perspective

    Directory of Open Access Journals (Sweden)

    Gizem Karaali


    Full Text Available Several academic institutions are searching for ways to help students develop their quantitative reasoning abilities and become more adept at higher-level tasks that involve quantitative skills. In this note we study the particular way Pomona College has framed this issue within its own context and what it plans to do about it. To this end we describe our efforts as members of a campus-wide committee that was assigned the duty of investigating the feasibility of founding a quantitative studies center on our campus. These efforts involved analysis of data collected through a faculty questionnaire, discipline-specific input obtained from each departmental representative, and a survey of what some of our peer institutions are doing to tackle these issues. In our studies, we identified three critical needs where quantitative support would be most useful in our case: tutoring and mentoring for entry-level courses; support for various specialized and analytic software tools for upper-level courses; and a uniform basic training for student tutors and mentors. We surmise that our challenges can be mitigated effectively via the formation of a well-focused and -planned quantitative studies center. We believe our process, findings and final proposal will be helpful to others who are looking to resolve similar issues on their own campuses.

    become a corporate enterprise or remain a patient welfare centered profession. A third approach involves an eclectic resolution of the two. Such amount of patient welfare as also ensures profit, and such amount of profit as also ensures patient welfare is to be forwarded. For, profit, without patient welfare, is blind. And patient welfare, without profit, is lame. According to this approach, medicine becomes a patient welfare centered professional enterprise. The various ramifications of each of these approaches are discussed in this monograph.

    Full Text Available Barbara E Ostrov,1 Kristine Reynolds,2 Lisabeth V Scalzi11Departments of Pediatrics and Medicine, 2Department of Nursing, Penn State Hershey Medical Center, Hershey, PA, USAPurpose: Direct feedback from patients about their preferred modes of medication ­administration has been increasingly sought by providers to develop care programs that best match patient goals. Multispecialty infusion centers generally provide care to hematology–oncology (HO and non-HO patients in one unit, with the same nursing staff. Our staff perceived that this was dissatisfying to our non-HO patients. We assessed patient satisfaction, as well as nursing and physician perceptions of patient preference/satisfaction with our infusion center, to determine whether a separate unit should be recommended when designing our new Cancer Institute Infusion Center.Patients and methods: A seven-question Likert scale satisfaction survey for patients, and a separate survey to assess nurses’ and physicians’ perception of patient satisfaction, were developed. The survey was administered to non-HO patients receiving infusions, doctors prescribing infusions, and nurses administering infusions. Results of the survey were compared between groups to assess differences in responses.Results: Responses were received from 52 non-HO patients, 18 physicians, and 13 nurses. Patients had more satisfaction, on all survey items, with the multispecialty infusion center than had been realized by physicians and nurses. Analysis demonstrated that patients were satisfied with care in a multispecialty infusion unit and were in favor of continuing their care in this combined center. Total scores of patient surveys were significantly different (P<0.001 from those of physicians and nurses, who had assumed patients would prefer to have their care in a non-HO infusion setting.Conclusion: Understanding patient preferences is an important step in deciding the structure of infusion centers.

The study ran Structural Equation Modelling (SEM by using AMOS program. Estimated method was used to calculate sample size then found 300 repondents, comprised : visitors and mall managers, school visitors, parents, school managers, Public Works department, and urban planning department .The study yielded a statistically significant correlation between  school and shopping center activity with congestion s. The result  indicated that school activity was positively related to congestion with p value  at p=0,000 (p ≤ 0,05. Shopping center activity was positively related to congestion with p value  at p=0,000 (p ≤ 0,05. The closer proximity from school to shooping center will causes severe traffic congestion. The relationship between school facility with proximity was found in p value at  p=0,000 (p ≤ 0,05 . The relationship between shopping center facility with proximity was found in p value at  p= 0,020 (p ≤ 0,05. While, the relationship between proximity with congestion was p= 0,008 (p ≤ 0,05. Monastery school and Mega Mall activity were affecting congestion because a closer proximity of two facilities. This indicates that the occurence of traffic congestion in Monastery School  may be dependent on existence of  Piere Tendean road link

  15. Progress to a Gallium-Arsenide Deep-Center Laser

    Directory of Open Access Journals (Sweden)

    Janet L. Pan


    Full Text Available Although photoluminescence from gallium-arsenide (GaAs deep-centers was first observed in the 1960s, semiconductor lasers have always utilized conduction-to-valence-band transitions. Here we review recent materials studies leading to the first GaAs deep-center laser. First, we summarize well-known properties: nature of deep-center complexes, Franck-Condon effect, hotoluminescence. Second, we describe our recent work: insensitivity of photoluminescence with heating, striking differences between electroluminescence and photoluminescence, correlation between transitions to deep-states and absence of bandgap-emission. Room-temperature stimulated-emission from GaAs deep-centers was observed at low electrical injection, and could be tuned from the bandgap to half-the-bandgap (900–1,600 nm by changing the electrical injection. The first GaAs deep-center laser was demonstrated with electrical injection, and exhibited a threshold of less than 27 mA/cm2 in continuous-wave mode at room temperature at the important 1.54 μm fiber-optic wavelength. This small injection for laser action was explained by fast depopulation of the lower state of the optical transition (fast capture of free holes onto deep-centers, which maintains the population inversion. The evidence for laser action included: superlinear L-I curve, quasi-Fermi level separations satisfying Bernard-Duraffourg’s criterion, optical gains larger than known significant losses, clamping of the optical-emission from lossy modes unable to reach laser action, pinning of the population distribution during laser action.

  4. - A Digital Library for Astronomy 101 (United States)

    Gagne, M.; Monahan, P.; Deustua, S.; Mason, B.


    The AAS is sponsoring the development of a digital collection of online resources for teaching introductory astronomy: Astronomy Center is part of the ComPADRE project with the AIP and its member organizations (see Deustua et al. at this meeting). The goal of Astronomy Center is to build a portal that will be a broad collection of high-quality digital resources, a useful and inviting interface to search and browse the collection, and an online meeting place for faculty at a variety of institutions to gather and share information. The collection will be launched in early 2005 and will initially contain a few hundred resources, selected primarily by Astronomy Center staff. The collection will grow through user and author submissions. Meanwhile, resources will be peer-reviewed and featured on the site as the collection grows. We will present the site, the user interface, some resources in the collection, the peer review process, and how members of the community can get involved with Astronomy Center. This work was made possible by a NSF National Science, Technology, Engineering and Mathematics Digital Library (NSDL) grant to the AAPT, AIP, and AAS.

  5. A Distributed Weighted Voting Approach for Accurate Eye Center Estimation

    Directory of Open Access Journals (Sweden)

    Gagandeep Singh


    Full Text Available This paper proposes a novel approach for accurate estimation of eye center in face images. A distributed voting based approach in which every pixel votes is adopted for potential eye center candidates. The votes are distributed over a subset of pixels which lie in a direction which is opposite to gradient direction and the weightage of votes is distributed according to a novel mechanism.  First, image is normalized to eliminate illumination variations and its edge map is generated using Canny edge detector. Distributed voting is applied on the edge image to generate different eye center candidates. Morphological closing and local maxima search are used to reduce the number of candidates. A classifier based on spatial and intensity information is used to choose the correct candidates for the locations of eye center. The proposed approach was tested on BioID face database and resulted in better Iris detection rate than the state-of-the-art. The proposed approach is robust against illumination variation, small pose variations, presence of eye glasses and partial occlusion of eyes.Defence Science Journal, 2013, 63(3, pp.292-297, DOI:

  7. Off-Center D- Centers in a Quantum Dot in the Presence of a Perpendicular Magnetic Fields

    Institute of Scientific and Technical Information of China (English)

    XIE Wen-Fang


    We investigate the effect of the position of the donor in quantum dots on the energy spectrum in the presence ofa perpendicular magnetic field by using the method of few-body physics. As a function of the magnetic field, we find, when D- centers are placed sufficiently off-center, discontinuous ground-state transitions which are similar to those found in many-electron parabolic quantum dots. Series of magic numbers of angular momentum which minimize the ground-state electron-electron interaction energy have been discovered. The dependence of the binding energy of the ground-state of the 1D- center on the dot radius for a few values of the magnetic field strength is obtained and compared with other results.

  8. Interdisciplinarity in work process at a Psychosocial Attention Center

    Full Text Available Objective: To analyze the work process of mental health professionals from a Psychosocial Attention Center (CAPS, from the knowledge and the practices applied in the production of care and its interface with user’s demands and the service offering. Methods: A case study with qualitative approach. Twenty-eight subjects joined in and were divided into three groups: I (eleven mental health workers, II (eleven users e III (six family members. The semistructured interview was used besides systematic observation, in the search for data about the work process of the professionals of the Psychosocial Attention Center, the relationship between team and user, offering and demand, access, technologies of care, knowledge and practices and interdisciplinarity. The investigation was based upon critical content analysis and was oriented by the flowchart analyzer. Results: The service organization and its work process are directed to the immediate supply of the population’s demands, which depicts a care based on prescriptive practices. Thus, the flow of assistance and the service offering complement each other in the need of a procedure and in its exhaustive offering by the service, dissolving interdisciplinary conductions of intervention shared with the user.Conclusion: Mental health care is still surrounded by biomedical hegemony centered in procedures directed to pharmacological prescription. Despite this reality, the work centered on the user and the utilization of soft technologies – communication, link, welcoming – begin to take part of the daily CAPS service offering, although it is only present in specific activities of certain procedures.

  15. Vote Centers as a Strategy to Control Election Administration Costs

    Directory of Open Access Journals (Sweden)

    David H. Folz


    Full Text Available The rising costs of election administration in an era of fiscal stress have motivated some local officials to test the feasibility of ideas for reducing election costs while enhancing voter convenience and perhaps even increasing voter turnout. One such pilot project in a suburban community in the South involved replacing precinct-based voting on election day with a vote center that all voters could use regardless of their precinct of residence. A comparison of election costs across two municipal elections showed that replacing precinct-based voting with an election day vote center resulted in substantial cost savings. While there was no statistical difference in voter turnout in municipal elections held before and after implementation of the pilot project, voters were highly satisfied with the convenience of the vote center as well as other aspects of their voting experience. The findings suggest that an election day vote center can be a viable strategy to control election costs and enhance voters’ perceptions of the convenience of voting.

  18. Development framework for a patient-centered record. (United States)

    Puentes, John; Roux, Michèle; Montagner, Julien; Lecornu, Laurent


    Patient records have been developed to support the physician-oriented medical activity scheme. One recommended yet rarely studied alternative, expected to improve healthcare, is the patient-centered record. We propose a development framework for such record, which includes domain-specific database models at the conceptual level, analyzing the fundamental role of complementary information destined to ensure proper patient understanding of related clinical situations. A patient-centered awareness field study of user requirements and medical workflow was carried out in three medical services and two technical units to identify the most relevant elements of the framework, and compared to the definitions of a theoretical approach. Three core data models - centered on the patient, medical personnel, and complementary patient information, corresponding to the determined set of entities, information exchanges and actors roles, constitute the technical recommendations of the development framework. An open source proof of concept prototype was developed to show the model feasibility. The resulting patient-centered record development framework implies particular medical personnel contributions to supply complementary information.

The purpose of NARSTO--a US-Canada-Mexico initiative of government agencies, industry, and the academic research community--is to improve the understanding of the formation and transport of tropospheric ozone.

  2. Developing a user-centered voluntary medical incident reporting system. (United States)

    Hua, Lei; Gong, Yang


    Medical errors are one of leading causes of death among adults in the United States. According to the Institute of Medicine, reporting of medical incidents could be a cornerstone to learn from errors and to improve patient safety, if incident data are collected in a properly structured format which is useful for the detection of patterns, discovery of underlying factors, and generation of solutions. Globally, a number of medical incident reporting systems were deployed for collecting observable incident data in care delivery organizations (CDO) over the past several years. However, few researches delved into design of user-centered reporting system for improving completeness and accuracy of medical incident collection, let alone design models created for other institutes to follow. In this paper, we introduce the problems identified in a current using voluntary reporting system and our effort is being made towards complete, accurate and useful user-centered new reporting system through a usability engineering process.

  3. A Center for Mideast Oceanographic Data in Muscat, Oman (United States)

    Ingle, S.; Belabbassi, L.; Du Vall, K.; Wang, Z.


    Lighthouse designed and installed a real-time cabled ocean observing system off the northern coast of the Sultanate of Oman in 2005 and a second system, farther to the south, existed as autonomous moorings from 2005-2009 and was upgraded to a real-time cabled system in early 2010. Since 2005 Lighthouse has operated and maintained those systems to produce a wealth of data on a poorly understood region of the global oceans. The systems record data hourly on current velocities over a range of depths, and temperature, pressure, conductivity, dissolved oxygen and turbidity at the depth of the sensor; the northern system also collects seismic and bottom pressure (tsunami detection) information continuously. Processing codes for all data have been developed and honed over the years in cooperation with oceanographers from Texas A&M University. As a joint and complementary effort, ocean circulation and tsunami impact models have been developed for the regional waters near Oman. In Oman, our work is coordinated through the Ministry of Agriculture and Fisheries Wealth. From the beginning, Lighthouse has intended to transition data processing and analysis over to the Sultanate. To facilitate this transition, we propose to establish a Center for Mideast Oceanographic Data located in Muscat, Oman that may also serve as a regional oceanographic data depository and research center. Main activities to be carried out include: marine data processing and management, training of Omani professionals in data processing and analysis, facilitating regional and international collaboration by hosting workshops or short courses, and employing the models for research purposes. The center would work with the newly-established Hazard Monitoring Center to develop modeled now- and forecast products for marine operations and safety. The goal is to house, in a single location, datasets and models that will help Oman manage and maintain its marine environment and resources for generations to come.

  6. Conductivity of a two-dimensional guiding center plasma. (United States)

    Montgomery, D.; Tappert, F.


    The Kubo method is used to calculate the electrical conductivity of a two-dimensional, strongly magnetized plasma. The particles interact through (logarithmic) electrostatic potentials and move with their guiding center drift velocities (Taylor-McNamara model). The thermal equilibrium dc conductivity can be evaluated analytically, but the ac conductivity involves numerical solution of a differential equation. Both conductivities fall off as the inverse first power of the magnetic field strength.

  7. Dimensionality of organizational justice in a call center context. (United States)

    Flint, Douglas; Haley, Lynn M; McNally, Jeffrey J


    Summary.-Employees in three call centers were surveyed about their perceptions of organizational justice. Four factors were measured: distributive justice, procedural justice, interpersonal justice, and informational justice. Structural equation modeling was employed to test whether a two-, three-, or four-factor model best fit the call center data. A three-factor model of distributive, procedural, and informational justice provided the best fit to these data. The three-factor model that showed the best fit does not conform to any of the more traditional models identified in the organizational justice literature. This implies that the context in which organizational justice is measured may play a role in identifying which justice factors are relevant to employees. Findings add to the empirical evidence on the dimensionality of organizational justice and imply that dimensionality of organizational justice is more context-dependent than previously thought.

  8. Using unfolding case studies in a subject-centered classroom. (United States)

    Day, Lisa


    The recently published report of the Carnegie Foundation's National Study of Nursing Education points out significant problems with classroom teaching in schools of nursing. This article suggests Palmer's idea of the subject-centered classroom as a way to transform nursing school classrooms into collaborative learning communities. For Palmer, the subject is the big idea of nursing practice-the nurse-patient/client/family/community relationship-that should take the lead in stimulating inquiry and discussion. The article goes on to describe how teachers can develop and use unfolding case studies to bring the subject to the center of the classroom. By doing so, the classroom becomes a place where students learn a sense of salience, develop their clinical imagination, and begin their formation as professional nurses.

  9. A Project of a Center for Astronomy Popularization (United States)

    Bravo-Alfaro, Hector

    At the Astronomy Department of Universidad de Guanajuato 400 km NW of Mexico City eight professional astronomers do research and undergraduate level teaching. In 2000 the facilities of a rudimentary observatory on the roof of the main building of the University were formally assigned to our Department. The site built in the late 1970s includes a 16-cm refractor in a dome and a classroom with capacity for 50 people. The refractor had been out of use for about twelve years. In general maintenance was inexistent and no up grade program had been considered at the time we took the site in charge. Since then with two portable 8-inch telescopes we organize astronomical observations for the general public specially scholars. However many repairs remain to be done of the building and refractor. So far we proposed a project to establish a Center for Popularization of Astronomy to get funds from the Regional Science Council with the aim to carry out the following activities: 1) Permanent program of astronomical observations for a wide audience. 2) Regular talks to the public in different science domains. 3) Summer schools in Astronomy for elementary and high-school teachers. 4) Foundation of an amateur society of astronomy.

  10. Mergers involving academic health centers: a formidable challenge. (United States)

    Pellegrini, V D


    Escalating economic pressures on the clinical enterprise threaten the missions of education and research in many of the most prestigious academic health centers. Following the model of industry, mergers of the healthcare delivery systems of teaching hospitals and clinics held promise for economies of scale and an improved operating margin. Failure to follow business principles in constructing the merged entity, differences in organizational governance and culture, and inability of physician leadership to prioritize, downsize, and consolidate clinical programs to optimize operational efficiencies all compromise the success of such mergers in academic medicine. Academic institutions and their respective governing boards need to exercise greater discipline in financial analysis and a willingness to make difficult decisions that show favor to one parent institution over another if mergers are to be effective in this setting. To date, an example of a vibrant and successful merger of academic health centers remains to be found.

    The fluorometer is the equipment used in chemical analysis laboratories, research institutes and nuclear fuel cycle companies. This equipment measures an unknown amount of uranium in ores, rivers, etc. The fluorometer functioning is based on the uranium fluorescence when submitted to the ultraviolet radiation incidence. The fluorescence is measured by an electronic optic system with optics filters, photomultiplier tube, and a current amplifier. The user centered design involves the user in the product development in all phases of the design process. Users are not simply consulted at the beginning of the design process and evaluated the system at the end; they are treated as partners throughout the design process. The user centered design emphasizes the needs and abilities of the users and improves the usability of the equipment. The activity centered design emphasizes the development of the equipment with a deep understanding of the users activities and of the current work practices of the users. The aim of this paper is to present a methodological framework that contributes to the design and evaluation of a new digital fluorometer towards an approach related to the users and their activities. This methodological framework includes users-based testing, interviews, questionnaires, human factors standards and guidelines, the users activity analysis and users satisfaction questionnaire.

  13. Cultivating Data Expertise and Roles at a National Research Center (United States)

    Thompson, C. A.


    As research becomes more computation and data-intensive, it brings new demands for staff that can manage complex data, design user services, and facilitate open access. Responding to these new demands, universities and research institutions are developing data services to support their scientists and scholarly communities. As more organizations extend their operations to research data, a better understanding of the staff roles and expertise required to support data-intensive research services is needed. What is data expertise - knowledge, skills, and roles? This study addresses this question through a case study of an exemplar research center, the National Center for Atmospheric Research (NCAR) in Boulder, CO. The NCAR case study results were supplemented and validated with a set of interviews of managers at additional geoscience data centers. To date, 11 interviews with NCAR staff and 19 interviews with managers at supplementary data centers have been completed. Selected preliminary results from the qualitative analysis will be reported in the poster: Data professionals have cultivated expertise in areas such as managing scientific data and products, understanding use and users, harnessing technology for data solutions, and standardizing metadata and data sets. Staff roles and responsibilities have evolved over the years to create new roles for data scientists, data managers/curators, data engineers, and senior managers of data teams, embedding data expertise into each NCAR lab. Explicit career paths and ladders for data professionals are limited but starting to emerge. NCAR has supported organization-wide efforts for data management, leveraging knowledge and best practices across all the labs and their staff. Based on preliminary results, NCAR provides a model for how organizations can build expertise and roles into their data service models. Data collection for this study is ongoing. The author anticipates that the results will help answer questions on what are

    CERN Document Server

    Holland, K; Pepé, M; Wiese, U J


    We discuss theories with the exceptional centerless gauge group G(2), paying attention to confinement and the pattern of chiral symmetry breaking. Exploiting the Higgs mechanism to break the symmetry down to SU(3), we also present how the familiar features of confinement and chiral symmetry breaking of SU(3) gauge theories reemerge. G(2) gauge theories show up as an unusual theoretical framework to study SU(3) gauge theories without the ``luxury'' of a center.

  15. A source-controlled data center network model. (United States)

    Yu, Yang; Liang, Mangui; Wang, Zhe


    The construction of data center network by applying SDN technology has become a hot research topic. The SDN architecture has innovatively separated the control plane from the data plane which makes the network more software-oriented and agile. Moreover, it provides virtual multi-tenancy, effective scheduling resources and centralized control strategies to meet the demand for cloud computing data center. However, the explosion of network information is facing severe challenges for SDN controller. The flow storage and lookup mechanisms based on TCAM device have led to the restriction of scalability, high cost and energy consumption. In view of this, a source-controlled data center network (SCDCN) model is proposed herein. The SCDCN model applies a new type of source routing address named the vector address (VA) as the packet-switching label. The VA completely defines the communication path and the data forwarding process can be finished solely relying on VA. There are four advantages in the SCDCN architecture. 1) The model adopts hierarchical multi-controllers and abstracts large-scale data center network into some small network domains that has solved the restriction for the processing ability of single controller and reduced the computational complexity. 2) Vector switches (VS) developed in the core network no longer apply TCAM for table storage and lookup that has significantly cut down the cost and complexity for switches. Meanwhile, the problem of scalability can be solved effectively. 3) The SCDCN model simplifies the establishment process for new flows and there is no need to download flow tables to VS. The amount of control signaling consumed when establishing new flows can be significantly decreased. 4) We design the VS on the NetFPGA platform. The statistical results show that the hardware resource consumption in a VS is about 27% of that in an OFS.

  18. A revisionist view of the integrated academic health center. (United States)

    Rodin, Judith


    Like many academic health centers that had expanded aggressively during the 1990s, the nation's first vertically integrated academic health center, the University of Pennsylvania Health System, was profoundly challenged by the dramatic and unanticipated financial impacts of the Balanced Budget Act of 1997. The author explains why-although Penn's Health System had lost $300 million over two years and its debts threatened to cause serious financial and educational damage to the rest of the University-Penn chose to manage its way out of the financial crisis (instead of selling or spinning off its four hospitals, clinical practices, and possibly even its medical school). A strategy of comprehensive integration has not only stabilized Penn's Health System financially, but strengthened its position of leadership in medical education, research, and health care delivery. The author argues that a strategy of greater horizontal integration offers important strategic advantages to academic health centers. In an era when major social and scientific problems demand broadly multidisciplinary and highly-integrated approaches, such horizontally integrated institutions will be better able to educate citizens and train physicians, develop new approaches to health care policy, and answer pressing biomedical research questions. Institutional cultural integration is also crucial to create new, innovative organizational structures that bridge traditional disciplinary, school, and clinical boundaries.

  20. A Cognitive Approach to Student-Centered e-Learning

    Energy Technology Data Exchange (ETDEWEB)

    Greitzer, Frank L.


    Like traditional classroom instruction, distance/electronic learning (e-Learning) derives from largely behaviorist computer-based instruction paradigms that tend to reflect passive training philosophies. Over the past thirty years, more flexible, student-centered classroom teaching methods have been advocated based on the concepts of ''discovery'' learning and ''active'' learning; student-centered approaches are likewise encouraged in the development of e-Learning applications. Nevertheless, many e-Learning applications that employ state-of-the art multimedia technology in which students interact with simulations, animations, video, and sounds still fail to meet their expected training potential. Implementation of multimedia-based training features may give the impression of engaging the student in more active forms of learning, but sophisticated use of multimedia features does not necessarily produce the desired effect. This paper briefly reviews some general guidelines for applying cognitive science principles to development of student-centered e-Learning applications and describes a cognitive approach to e-Learning development that is being undertaken for the US Army.

  1. Center mode of a doubly resonant optical periodic structure (United States)

    Alagappan, G.; Png, C. E.


    An optical periodic structure with a single spatial resonance exhibits a stopband. When a second spatial resonance very close to the first one is added, the resulting doubly resonant structure exhibits a Gaussian enveloped, high quality factor transmission state right at the center of the original stopband. Using a slowly varying envelope approximation, we describe the optical characteristics of this transmission state analytically. The transmission state exists despite an optical structure of low refractive index contrast, and has potential applications in nano-optics, and photonics.

  2. Six Sigma and Lean concepts, a case study: patient centered care model for a mammography center. (United States)

    Viau, Mark; Southern, Becky


    Boca Raton Community Hospital in South Florida decided to increase return while enhancing patient experience and increasing staff morale. They implemented a program to pursue "enterprise excellence" through Six Sigma methodologies. In order to ensure the root causes to delays and rework were addressed, a multigenerational project plan with 3 major components was developed. Step 1: Stabilize; Step 2: Optimize; Step 3: Innovate. By including staff and process owners in the process, they are empowered to think differently about what they do and how they do it. A team that works collaboratively to identify problems and develop solutions can only be a positive to any organization.

  4. Toward a narrative-centered curriculum for nurse practitioners. (United States)

    Swenson, M M; Sims, S L


    This paper discusses various alternative and nontraditional teaching strategies currently used in nurse practitioner curricula. These instructional strategies include case-study analysis (Ryan-Wenger & Lee, 1997) and problem-based learning/practice-based learning (Barrows, 1994). We suggest a further evolution, using principles and practices of a narrative pedagogy (Diekelmann, 1995) to allow convergence of these several narratively-focused inductive and interpretive approaches. This combination of ways of learning has led us toward a narrative-centered curriculum for family nurse practitioners (FNPs). Specific ways to use narrative in the FNP curriculum are presented to demonstrate how to take the curriculum beyond traditional ways of teaching and learning.

    Shared decision making (SDM) is regarded as an ideal in chronic illness care but is difficult to implement in practice. Communication and reflection play an important role and need further investigation. Using grounded theory, we studied patient-provider interaction in a difficult and advanced area......: managing poorly controlled diabetes. A person-centered communication and reflection model was developed, identifying SDM in chronic care to be a question of professionals gaining insight into patients' decisions, rather than the opposite. The model reveals important choices in communication and reflection...

  7. Wings: A New Paradigm in Human-Centered Design (United States)

    Schutte, Paul C.


    Many aircraft accidents/incidents investigations cite crew error as a causal factor (Boeing Commercial Airplane Group 1996). Human factors experts suggest that crew error has many underlying causes and should be the start of an accident investigation and not the end. One of those causes, the flight deck design, is correctable. If a flight deck design does not accommodate the human's unique abilities and deficits, crew error may simply be the manifestation of this mismatch. Pilots repeatedly report that they are "behind the aircraft" , i.e., they do not know what the automated aircraft is doing or how the aircraft is doing it until after the fact. Billings (1991) promotes the concept of "human-centered automation"; calling on designers to allocate appropriate control and information to the human. However, there is much ambiguity regarding what it mean's to be human-centered. What often are labeled as "human-centered designs" are actually designs where a human factors expert has been involved in the design process or designs where tests have shown that humans can operate them. While such designs may be excellent, they do not represent designs that are systematically produced according to some set of prescribed methods and procedures. This paper describes a design concept, called Wings, that offers a clearer definition for human-centered design. This new design concept is radically different from current design processes in that the design begins with the human and uses the human body as a metaphor for designing the aircraft. This is not because the human is the most important part of the aircraft (certainly the aircraft would be useless without lift and thrust), but because he is the least understood, the least programmable, and one of the more critical elements. The Wings design concept has three properties: a reversal in the design process, from aerodynamics-, structures-, and propulsion-centered to truly human-centered; a design metaphor that guides function

  8. A patient-centered approach to nurse orientation. (United States)

    Bumgarner, S D; Biggerstaff, G H


    An orientation pathway was developed using a patient-centered approach. The pathway provides a guide or "road map" for the preceptor and new nurse to care for high-volume patient populations in medical and surgical units. Benefits include application of the nursing process, promotion of critical thinking skills, reduction of reality shock, and improvement in job satisfaction and retention. This article describes the rationale behind the approach and its application to nurse orientation. Steps in the process are described. Staff development educators can use the steps to develop orientation pathways for other practice settings.

  9. Case study: a data warehouse for an academic medical center. (United States)

    Einbinder, J S; Scully, K W; Pates, R D; Schubart, J R; Reynolds, R E


    The clinical data repository (CDR) is a frequently updated relational data warehouse that provides users with direct access to detailed, flexible, and rapid retrospective views of clinical, administrative, and financial patient data for the University of Virginia Health System. This article presents a case study of the CDR, detailing its five-year history and focusing on the unique role of data warehousing in an academic medical center. Specifically, the CDR must support multiple missions, including research and education, in addition to administration and management. Users include not only analysts and administrators but clinicians, researchers, and students.

  10. A phenomenological investigation of science center exhibition developers' expertise development (United States)

    Young, Denise L.

    The purpose of this study was to examine the exhibition developer role in the context of United States (U.S.) science centers, and more specifically, to investigate the way science center exhibition developers build their professional expertise. This research investigated how successfully practicing exhibition developers described their current practices, how they learned to be exhibition developers, and what factors were the most important to the developers in building their professional expertise. Qualitative data was gathered from 10 currently practicing exhibition developers from three science centers: the Exploratorium, San Francisco, California; the Field Museum, Chicago, Illinois; and the Science Museum of Minnesota, St. Paul, Minnesota. In-depth, semistructured interviews were used to collect the data. The study embraced aspects of the phenomenological tradition and sought to derive a holistic understanding of the position and how expertise was built for it. The data were methodically coded and organized into themes prior to analysis. The data analysis found that the position consisted of numerous and varied activities, but the developers' primary roles were advocating for the visitor, storytelling, and mediating information and ideas. They conducted these activities in the context of a team and relied on an established exhibition planning process to guide their work. Developers described a process of learning exhibition development that was experiential in nature. Learning through daily practice was key, though they also consulted with mentors and relied on visitor studies to gauge the effectiveness of their work. They were adept at integrating prior knowledge gained from many aspects of their lives into their practice. The developers described several internal factors that contributed to their expertise development including the desire to help others, a natural curiosity about the world, a commitment to learning, and the ability to accept critique. They

  12. Double Star Research: A Student-Centered Community of Practice (United States)

    Johnson, Jolyon


    Project and team-based pedagogies are increasingly augmenting lecture-style science classrooms. Occasionally, university professors will invite students to tangentially partcipate in their research. Since 2006, Dr. Russ Genet has led an astronomy research seminar for community college and high school students that allows participants to work closely with a melange of professional and advanced amatuer researchers. The vast majority of topics have centered on measuring the position angles and searations of double stars which can be readily published in the Journal of Double Star Observations. In the intervening years, a collaborative community of practice (Wenger, 1998) formed with the students as lead researchers on their projects with the guidance of experienced astronomers and educators. The students who join the research seminar are often well prepared for further STEM education in college and career. Today, the research seminar involves multile schools in multiple states with a volunteer educator acting as an assistant instructor at each location. These assistant instructors interface with remote observatories, ensure progress is made, and recruit students. The key deliverables from each student team include a published research paper and a public presentation online or in-person. Citing a published paper on scholarship and college applications gives students' educational carreers a boost. Recently the Journal of Double Star Observations published its first special issue of exlusively student-centered research.

  13. Optimal Design of a Center Support Quadruple Mass Gyroscope (CSQMG). (United States)

    Zhang, Tian; Zhou, Bin; Yin, Peng; Chen, Zhiyong; Zhang, Rong


    This paper reports a more complete description of the design process of the Center Support Quadruple Mass Gyroscope (CSQMG), a gyro expected to provide breakthrough performance for flat structures. The operation of the CSQMG is based on four lumped masses in a circumferential symmetric distribution, oscillating in anti-phase motion, and providing differential signal extraction. With its 4-fold symmetrical axes pattern, the CSQMG achieves a similar operation mode to Hemispherical Resonant Gyroscopes (HRGs). Compared to the conventional flat design, four Y-shaped coupling beams are used in this new pattern in order to adjust mode distribution and enhance the synchronization mechanism of operation modes. For the purpose of obtaining the optimal design of the CSQMG, a kind of applicative optimization flow is developed with a comprehensive derivation of the operation mode coordination, the pseudo mode inhibition, and the lumped mass twisting motion elimination. The experimental characterization of the CSQMG was performed at room temperature, and the center operation frequency is 6.8 kHz after tuning. Experiments show an Allan variance stability 0.12°/h (@100 s) and a white noise level about 0.72°/h/√Hz, which means that the CSQMG possesses great potential to achieve navigation grade performance.

  15. Are we living near the center of a local void?

    CERN Document Server

    Cusin, Giulia; Uzan, Jean-Philippe


    The properties of the cosmic microwave background (CMB) temperature and polarisation anisotropies measured by a static, off-centered observer located in a local spherically symmetric void, are described. In particular in this paper we compute, together with the standard 2- point angular correlation functions, the off-diagonal correlators, which are no more vanishing by symmetry. While the energy shift induced by the off-centered position of the observer can be suppressed by a proper choice of the observer velocity, a lensing-like effect on the CMB emission point remains. This latter effect is genuinely geometrical (e.g. non-degenerate with a boost) and reflects in the structure of the off-diagonal correlators. At lowest order in this effect, the temperature and polarisation correlation matrices have non-vanishing diagonal elements, as usual, and all the off-diagonal terms are excited. This particular signature of a local void model allows one, in principle, to disentangle geometrical effects from local kinema...

    The expansion center Universe gives a dipole anisotropy to the Hubble law, at any Hubble depth D. After a long series of successful dipole tests on the nearby Universe, using historic data sets of about half a century, and that carried out on 53 SCP SNe Ia ranging around the average redshift =0.5 (ECM paper VI: SAIt2004 in Milan), here is a crucial multiple dipole test at z bins centred on the mean =1.0, or Hubble depth D=c/H0, and based on data from SCP Union compilation (SCPU: Kowalski et al. 2008) and SCP Union2 (SCPU2: Amanullah et al. 2010), including those obtained within "The new wedge-shaped Hubble diagram of 398 SCP supernovae..." (ECM paper IX: SAIt2010 in Naples). Table 5abc lists data of two main samples, with 48 SCPU SNe Ia and 58 SCPU2 SNe Ia respectively. The confirmed dipole anisotropy, shown by 6 primary sample tests and by another 27 from 9 encapsulated z bins with D=DL/(1+z), gives a model independent result, in full accordance with the expansion center model. This means a maximum cz range ...

    Priscila Tadei Nakata


    Full Text Available OBJECTIVE: to identify and classify the degree of family risk in a Family Health Center by means of a multidimensional evaluation instrument. METHOD: a cross-sectional study, with a quantitative and descriptive design, which evaluated 927 families registered in the center, which covers five micro-areas. The Coelho and Savassi Scale was applied, this consisting of 13 sentinels of evaluation of the social risk, using secondary data available in the File A of the families' medical records, in the last trimester of 2011. The data was analyzed using the SPSS (Statistical Package for the Social Sciences for Windows software, version 18.0. RESULTS: among the families studied, 68.5% were classified as not being at risk. It was ascertained that the smallest proportion of at-risk families (8.2% was found in micro-area 1, and that micro-area 4 had the highest proportion (55.9%. The most-prevalent risk situations were poor conditions of basic sanitation, systemic arterial hypertension, diabetes mellitus and drug addiction. CONCLUSION: this study's results make it possible to create support for the planning of home visits, to implement health surveillance actions, and for health professionals to better understand the vulnerabilities of the families attended.

    High field (W-band, 95 GHz) pulsed electron-nuclear double resonance (ENDOR) measurements were carried out on a number of proteins that contain the mixed-valence, binuclear electron-mediating Cu(A) center. These include nitrous oxide reductase (N(2)OR), the recombinant water-soluble fragment...... of subunit II of Thermus thermophilus cytochrome c oxidase (COX) ba(3) (M160T9), its M160QT0 mutant, where the weak axial methionine ligand has been replaced by a glutamine, and the engineered "purple" azurin (purpAz). The three-dimensional (3-D) structures of these proteins, apart from the mutant, are known...... indicates differences in the positions of the imidazole rings relative to the Cu(2)S(2) core. Comparison of the spectral features of the weakly coupled protons of M160QT0 with those of the other investigated proteins shows that they are very similar to those of purpAz, where the Cu(A) center is the most...

  20. A Python Based Metal Center Parameter Builder. (United States)

    Li, Pengfei; Merz, Kenneth M

    2016-04-25, a python based metal center parameter builder, has been developed to build force fields for the simulation of metal complexes employing the bonded model approach. It has an optimized code structure, with far fewer required steps than the previous developed MCPB program. It supports various AMBER force fields and more than 80 metal ions. A series of parametrization schemes to derive force constants and charge parameters are available within the program. We give two examples (one metalloprotein example and one organometallic compound example), indicating the program's ability to build reliable force fields for different metal ion containing complexes. The original version was released with AmberTools15. It is provided via the GNU General Public License v3.0 (GNU_GPL_v3) agreement and is free to download and distribute. provides a bridge between quantum mechanical calculations and molecular dynamics simulation software packages thereby enabling the modeling of metal ion centers. It offers an entry into simulating metal ions in a number of situations by providing an efficient way for researchers to handle the vagaries and difficulties associated with metal ion modeling.

  1. A multi-pathway model for Photosynthetic reaction center

    CERN Document Server

    Qin, M; Yi, X X


    Charge separation in light-harvesting complexes occurs in a pair of tightly coupled chlorophylls at the heart of photosynthetic reaction centers of both plants and bacteria. Recently it has been shown that quantum coherence can, in principle, enhance the efficiency of a solar cell, working like a quantum heat engine (QHE). Here, we propose a biological quantum heat engine (BQHE) motivated by Photosystem {\\rm II} reaction center (PS{\\rm II} RC) to describe the charge separation. Our model mainly considers two charge-separation pathways more than that in the published literature. The two pathways can interfere via cross-couplings and work together to enhance the charge-separation yields. We explore how these cross-couplings increase the current and voltage of the charge separation and discuss the advantages of multiple pathways in terms of current and power. The robustness of the BQHE against the charge recombination in natural PS{\\rm II} RC and dephasing induced by environments is also explored, and extension ...

  2. Largest Empty Circle Centered on a Query Line

    Augustine, John; Roy, Sasanka


    The Largest Empty Circle problem seeks the largest circle centered within the convex hull of a set $P$ of $n$ points in $\\mathbb{R}^2$ and devoid of points from $P$. In this paper, we introduce a query version of this well-studied problem. In our query version, we are required to preprocess $P$ so that when given a query line $Q$, we can quickly compute the largest empty circle centered at some point on $Q$ and within the convex hull of $P$. We present solutions for two special cases and the general case; all our queries run in $O(\\log n)$ time. We restrict the query line to be horizontal in the first special case, which we preprocess in $O(n \\alpha(n) \\log n)$ time and space, where $\\alpha(n)$ is the slow growing inverse of the Ackermann's function. When the query line is restricted to pass through a fixed point, the second special case, our preprocessing takes $O(n \\alpha(n)^{O(\\alpha(n))} \\log n)$ time and space. We use insights from the two special cases to solve the general version of the problem with pr...

  4. Analysis of a Hybrid Wing Body Center Section Test Article (United States)

    Wu, Hsi-Yung T.; Shaw, Peter; Przekop, Adam


    The hybrid wing body center section test article is an all-composite structure made of crown, floor, keel, bulkhead, and rib panels utilizing the Pultruded Rod Stitched Efficient Unitized Structure (PRSEUS) design concept. The primary goal of this test article is to prove that PRSEUS components are capable of carrying combined loads that are representative of a hybrid wing body pressure cabin design regime. This paper summarizes the analytical approach, analysis results, and failure predictions of the test article. A global finite element model of composite panels, metallic fittings, mechanical fasteners, and the Combined Loads Test System (COLTS) test fixture was used to conduct linear structural strength and stability analyses to validate the specimen under the most critical combination of bending and pressure loading conditions found in the hybrid wing body pressure cabin. Local detail analyses were also performed at locations with high stress concentrations, at Tee-cap noodle interfaces with surrounding laminates, and at fastener locations with high bearing/bypass loads. Failure predictions for different composite and metallic failure modes were made, and nonlinear analyses were also performed to study the structural response of the test article under combined bending and pressure loading. This large-scale specimen test will be conducted at the COLTS facility at the NASA Langley Research Center.

  5. Centers of excellence: a medical measurement or marketing myth? (United States)

    Meyer, L C


    Managed care organizations, physician groups and hospital systems are all increasingly pressured to identify new modes of treatment that produce verifiable outcomes while reducing the revolving door pattern of health care for the chronically ill. Providers are also faced with creating systems of care to differentiate themselves from the competition in the marketplace. Disease-specific health management programs are being used to address both issues. When used properly, they can be promising tools in the battle to maintain health care quality while containing costs. Skillful balancing of these two important factors can ensure maximum value for both patients and payers. Are centers of excellence the critical pathway of the future? Or are they merely a marketing ploy to generate incremental growth and profitability for savvy business executives and medical group management entrepreneurs? This article provides an overview of the center of excellence concept, addresses its misuse in the industry and discusses the strategic and marketing implications for organizations considering this approach as a tool to demonstrate full accountability and meritorious outcomes.

  6. A new job migration algorithm to improve data center efficiency

    CERN Document Server

    Calzolari, Federico


    The under exploitation of the available resources risks to be one of the main problems for a computing center. The growing demand of computational power necessarily entails more complex approaches in the management of the computing resources, with particular attention to the batch queue system scheduler. In a heterogeneous batch queue system, available for both serial single core processes and parallel multi core jobs, it may happen that one or more computational nodes composing the cluster are not fully occupied, running a number of jobs lower than their actual capability. A typical case is represented by more single core jobs running each one over a different multi core server, while more parallel jobs - requiring all the available cores of a host - are queued. A job rearrangement executed at runtime is able to free extra resources, in order to host new processes. We present an efficient method to improve the computing resources exploitation.

  7. Incorporating the USAF Flight Center's TQM plan in a hospital. (United States)

    Bridges, R D; Mathews, K A


    A total quality management (TQM) plan has been instituted by the United States Air Force Flight Test Center at Edwards Air Force Base. To determine the feasibility of implementing the same basic TQM plan in a district hospital, a joint industry-government team was established. Five areas of concentration were selected for review: infrastructure, methodology, training, strategic plan, and a "Quality Bill of Rights." The TQM "infrastructure" is intended to match and complement the existing organizational structure and chain of command, not to supplant it. As the overall plan seemed well-adapted for implementation in a hospital setting, a three-phase implementation approach was identified that included conceptual planning, initial training and goal setting, and full-scale implementation. Each phase is described in terms of objectives, staffing, and timing requirements.

  8. A Multidimensional Data Warehouse for Community Health Centers. (United States)

    Kunjan, Kislaya; Toscos, Tammy; Turkcan, Ayten; Doebbeling, Brad N


    Community health centers (CHCs) play a pivotal role in healthcare delivery to vulnerable populations, but have not yet benefited from a data warehouse that can support improvements in clinical and financial outcomes across the practice. We have developed a multidimensional clinic data warehouse (CDW) by working with 7 CHCs across the state of Indiana and integrating their operational, financial and electronic patient records to support ongoing delivery of care. We describe in detail the rationale for the project, the data architecture employed, the content of the data warehouse, along with a description of the challenges experienced and strategies used in the development of this repository that may help other researchers, managers and leaders in health informatics. The resulting multidimensional data warehouse is highly practical and is designed to provide a foundation for wide-ranging healthcare data analytics over time and across the community health research enterprise.

  9. Automated Determination of a Package's Center of Mass

    Directory of Open Access Journals (Sweden)

    Ayaz Hemani


    Full Text Available In order to address the issue of increased efficiency and better planning for parcel shipments, an automated computer program was developed in Microsoft Excel that calculates center of mass and moments of mass with greater speed and reliability than currently implemented systems. This simple program requires only a variable density function and limits of integration for a given object as input within the spreadsheet system. Once the required input has been provided, a series of chain calculations, with the help of a Visual Basic for Applications (VBA script, is able to process the input, which is done through integration and a Riemann sum. Furthermore, the foundation of the program can also be used for calculating other physical quantities of interest such as the moment of inertia or surface area of an object.

  10. The Galactic Center - an AGN on a starvation diet

    CERN Document Server

    Biermann, P L; Biermann, Heino Falcke & Peter L.


    The Galactic Center shows evidence for the presence of three important AGN ingredients: a Black Hole ($M_\\bullet\\sim10^6M_\\odot$), an accretion disk ($10^{-8.5} - 10^{-7} M_\\odot/{\\rm yr}$) and a powerful jet (jet power $\\ge$ 10\\% disk luminosity). However, the degree of activity is very low and can barely account for the energetics of the whole central region. Neverthelss, in the very inner arsecond the central engine becomes dominant and provides an interesting laboratory for the physics of central engines (Black Holes) in galactic nuclei. We therefore give an overall picture of the central arcsecond where we link the radio emission and the heating of the ambient medium to a weakly accreting disk surrounding a massive Black Hole.

    Brown, Forbes T


    For today's students, learning to model the dynamics of complex systems is increasingly important across nearly all engineering disciplines. First published in 2001, Forbes T. Brown's Engineering System Dynamics: A Unified Graph-Centered Approach introduced students to a unique and highly successful approach to modeling system dynamics using bond graphs. Updated with nearly one-third new material, this second edition expands this approach to an even broader range of topics. What's New in the Second Edition? In addition to new material, this edition was restructured to build students' competence in traditional linear mathematical methods before they have gone too far into the modeling that still plays a pivotal role. New topics include magnetic circuits and motors including simulation with magnetic hysteresis; extensive new material on the modeling, analysis, and simulation of distributed-parameter systems; kinetic energy in thermodynamic systems; and Lagrangian and Hamiltonian methods. MATLAB(R) figures promi...

I build on my previous work (COLING90) that accounted for the alternation of null and strong pronouns in subject position. I extend my previous analysis in several ways: for example, I refine the notion of {\\sc continue} and discuss the centering functions of full NPs.

    Jay C. Almlie; Bruce Wood; Rich Schlupp


    In November 2005, the Energy & Environmental Research Center (EERC), ePowerSynergies, Inc. (ePSI), and Resurfice Corporation teamed to develop, produce, and demonstrate the world's first and only fuel cell-powered ice resurfacer. The goals of this project were: {sm_bullet} To educate the public on the readiness, practicality, and safety of fuel cells powered by hydrogen fuel and {sm_bullet} To establish a commercialization pathway in an early-adopter, niche market. The vehicle was developed and produced in a short 3-month span. The vehicle made its world debut at U.S. Senator Byron Dorgan's (D-ND) 2005 Hydrogen Energy Action Summit. Subsequently, the vehicle toured North America appearing at numerous public events and conferences, receiving much attention from international media outlets.

  18. Applying a User-Centered Approach to Interactive Visualisation Design (United States)

    Wassink, Ingo; Kulyk, Olga; van Dijk, Betsy; van der Veer, Gerrit; van der Vet, Paul

    Analysing users in their context of work and finding out how and why they use different information resources is essential to provide interactive visualisation systems that match their goals and needs. Designers should actively involve the intended users throughout the whole process. This chapter presents a user-centered approach for the design of interactive visualisation systems. We describe three phases of the iterative visualisation design process: the early envisioning phase, the global specification phase, and the detailed specification phase. The whole design cycle is repeated until some criterion of success is reached. We discuss different techniques for the analysis of users, their tasks and domain. Subsequently, the design of prototypes and evaluation methods in visualisation practice are presented. Finally, we discuss the practical challenges in design and evaluation of collaborative visualisation environments. Our own case studies and those of others are used throughout the whole chapter to illustrate various approaches.

    Antenna apertures that are tapered for sidelobe control can also be parsed into subapertures for Direction of Arrival (DOA) measurements. However, the aperture tapering complicates phase center location for the subapertures, knowledge of which is critical for proper DOA calculation. In addition, tapering affects subaperture gains, making gain dependent on subaperture position. Techniques are presented to calculate subaperture phase center locations, and algorithms are given for equalizing subapertures’ gains. Sidelobe characteristics and mitigation are also discussed.

  4. Application of theory to family-centered care: a role for social workers. (United States)

    Miller, Gary


    Family-centered care is an emerging trend in health care settings today. An explanation, principles, and a definition of family-centered care are offered and discussed. A theoretical framework, Balance Theory of Coordination, which can be utilized by social workers to develop and enhance family-centered care practices, is explained and discussed. Various family-centered care practices are examined within the context of Balance Theory of Coordination as examples.

  5. Local Molecular Orbitals from a Projection onto Localized Centers. (United States)

    Heßelmann, Andreas


    A localization method for molecular orbitals is presented which exploits the locality of the eigenfunctions associated with the largest eigenvalues of the matrix representation of spatially localized functions. Local molecular orbitals are obtained by a projection of the canonical orbitals onto the set of the eigenvectors which correspond to the largest eigenvalues of these matrices. Two different types of spatially localized functions were chosen in this work, a two-parameter smooth-step-type function and the weight functions determined by a Hirshfeld partitioning of the molecular volume. It is shown that the method can provide fairly local occupied molecular orbitals if the positions of the set of local functions are set to the molecular bond centers. The method can also yield reasonably well-localized virtual molecular orbitals, but here, a sensible choice of the positions of the functions are the atomic sites and the locality then depends more strongly on the shape of the set of local functions. The method is tested for a range of polypeptide molecules in two different conformations, namely, a helical and a β-sheet conformation. Futhermore, it is shown that an adequate locality of the occupied and virtual orbitals can also be obtained for highly delocalized systems.

  6. A New View of Molecular Gas in the Galactic Center (United States)

    Mills, Elisabeth A.; Morris, M.; Güsten, R.; Requena Torres, M.; Lang, C. C.; Butterfield, N.; Ott, J.


    On average, the molecular gas in the center of our Galaxy is significantly hotter (T = 50-300 K), denser (n > 10^4 cm^-3), and more turbulent than gas in the rest of the disk. I will present results from a recent series of observations that indicate that our understanding of the Galactic center (GC) molecular gas is incomplete, and that conditions in some clouds are even more extreme than previously thought. Using the Green Bank telescope, we have measured a very hot molecular gas component (T = 400-500 K ) in three largely quiescent GC giant molecular clouds using metastable inversion lines of ammonia from (8,8) to (15,15) . We further detect the (9,9) line in seven other GC clouds, indicating that this hot gas component may be a common feature of GC clouds, potentially yielding insight into the heating source of the molecular gas in this region. In addition, I will present new density constraints for the circumnuclear disk (CND), a reservoir of gas and dust 1.5 parsecs in radius from the central supermassive black hole, Sgr A*. Recent estimates of the CND density vary by four orders of magnitude, which makes its future evolution uncertain: gas in the CND could either accrete onto the black hole, dissipate, or, if the density is higher than 10^7 cm^-3, exist in gravitationally-stable clumps capable of forming stars. However, our APEX measurements of highly excited lines of HCN and HCO+ indicate that although the CND gas is denser than most other GC clouds, it is not likely to be tidally stable and thus is unlikely to host star formation. Finally, I will present early results from a new Very Large Array study of gas on sub-parsec scales in a sample of GC clouds, all of which exhibit unexpectedly abundant Class I methanol maser emission. The widespread distribution of these masers suggests shocks play an important role in driving cloud evolution throughout this unique region of our Galaxy.

  7. A new conceptual framework for academic health centers. (United States)

    Borden, William B; Mushlin, Alvin I; Gordon, Jonathan E; Leiman, Joan M; Pardes, Herbert


    Led by the Affordable Care Act, the U.S. health care system is undergoing a transformative shift toward greater accountability for quality and efficiency. Academic health centers (AHCs), whose triple mission of clinical care, research, and education serves a critical role in the country's health care system, must adapt to this evolving environment. Doing so successfully, however, requires a broader understanding of the wide-ranging roles of the AHC. This article proposes a conceptual framework through which the triple mission is expanded along four new dimensions: health, innovation, community, and policy. Examples within the conceptual framework categories, such as the AHCs' safety net function, their contributions to local economies, and their role in right-sizing the health care workforce, illustrate how each of these dimensions provides a more robust picture of the modern AHC and demonstrates the value added by AHCs. This conceptual framework also offers a basis for developing new performance metrics by which AHCs, both individually and as a group, can be held accountable, and that can inform policy decisions affecting them. This closer examination of the myriad activities of modern AHCs clarifies their essential role in our health care system and will enable these institutions to evolve, improve, be held accountable for, and more fully serve the health of the nation.

    For over a decade, students from Cuesta College and number of high schools have engaged in astronomical research during one-term seminars. A community of practice - consisting of students, educators, and astronomers - has formed that is centered on supporting the students' astronomical research. The seminar has recently adopted distance education technology and automated telescopes in a hybrid form of on-line and inperson collaborations between students, educators, and astronomers. This hybridization is not only resulting in new areas of growth and opportunity, but has created a number of challenges. For example, as more schools joined this seminar, standardized teaching materials such as a textbook and self-paced, online learning units had to be developed. Automated telescopes devoted to expanding student research opportunities within this community of practice are being brought on line by Concordia University and the Boyce Research Initiatives and Educational Foundation. The Institute for Student Astronomical Research supports this growing community in many ways including maintaining a website and editing books of student papers published through the Collins Foundation Press.

  10. Diabetes in a primary care center among Spaniards and immigrants

    Directory of Open Access Journals (Sweden)

    Roca Vilalta M


    Full Text Available Diabetes is a disease with different prevalence in different populations. Objectives: The aim of the present study is to describe diabetic patients in a primary care center with regard to their geographic origin, and to determine the status of their disease. Methods: A cross-sectional descriptive study, with data available from clinical records in South Tarrasa primary care center (Barcelona, Spain in 2004. Results: A total of 1215 diabetic patients with an average age of 65 years, 51% female, were included in the study. Regarding their origin, 97% were from Spain, 2% from Morocco, 0.8% from Latin America, and 0.2% from the rest of Europe. The average Hb1AC was 6.9%. In type 2 diabetic patients, treatment consisted of oral hypoglycemic agents (OHA for 46.6%, only dietetic restrictions for 36.5%, OHA + insulin for 7.9%, and only insulin for 9%. In the age group 30-39 years, 0.7% of Moroccans suffer from diabetes versus 0.5% of Spaniards. The values in the 40-49 year group are 3.9% of Moroccans, 3% of Spaniards, and 2.1% of Latin Americans. The values in the 50-59 year group are 13.5% of Moroccans, 10.6% of Spaniards, and 7.7% of Latin Americans. The values in the 60-69 year group are 40% of Moroccans, 18.8% of Spaniards, and 44.5% of Latin Americans. The values in the 70-79 year group are 67% of Moroccans, 26% of Spaniards, and 50% of Latin Americans. The average Hb1AC was 6.3% in Latin Americans, 6.9% in Spaniards, and 8.1% in Moroccans. In type 1 diabetic patients, the average Hb1AC was 10.2% in Moroccans and 8% in Spaniards; while in type 2 diabetes, the average Hb1AC was 7.8% in Moroccans and 6.9% in Spaniards. Gestational diabetes was observed in 6.1% of the Spanish, 10.9% of the Moroccan and 4.2% of the Latin American women. Conclusions: A higher prevalence of diabetes was detected in Moroccans than in patients from other countries. These patients present poor control of the disease.

  11. Establishing a Secure Data Center with Remote Access: Preprint

    Energy Technology Data Exchange (ETDEWEB)

    Gonder, J.; Burton, E.; Murakami, E.


    Access to existing travel data is critical for many analysis efforts that lack the time or resources to support detailed data collection. High-resolution data sets provide particular value, but also present a challenge for preserving the anonymity of the original survey participants. To address this dilemma of providing data access while preserving privacy, the National Renewable Energy Laboratory and the U.S. Department of Transportation have launched the Transportation Secure Data Center (TSDC). TSDC data sets include those from regional travel surveys and studies that increasingly use global positioning system devices. Data provided by different collecting agencies varies with respect to formatting, elements included and level of processing conducted in support of the original purpose. The TSDC relies on a number of geospatial and other analysis tools to ensure data quality and to generate useful information outputs. TSDC users can access the processed data in two different ways. The first is by downloading summary results and second-by-second vehicle speed profiles (with latitude/longitude information removed) from a publicly-accessible website. The second method involves applying for a remote connection account to a controlled-access environment where spatial analysis can be conducted, but raw data cannot be removed.

  12. Dofetilide in Overdose: A Case Series from Poison Center Data. (United States)

    Hieger, M A; Maskell, K F; Moss, M J; Powell, S W; Cumpston, K L


    Dofetilide is a class III antiarrhythmic used for treating atrial dysrhythmias. Though its adverse effects are well described in routine use, very little is known about dofetilide toxicity in overdose. This is a retrospective case series of consecutive patients reported to our poison center after dofetilide overdose. Twenty-seven cases were included. Seventeen patients were treated at a healthcare facility, and of these, eight were admitted. Twenty-one patients took one extra capsule, four took someone else's medication, one took three extra capsules, and one had a large intentional overdose. Ten patients had co-ingestants reported, including three QT-prolonging agents. No one required cardioversion, defibrillation, CPR, or overdrive pacing. The patient who reported taking 90 times his usual dose in suicide attempt was the only patient to have significant clinical effects. He experienced an 8-beat run of non-sustained ventricular tachycardia, frequent multifocal PVCs, and ventricular bigeminy. He received magnesium sulfate and potassium chloride supplementation. In this series, unintentional small overdoses did not result in significant clinical effects and were often managed successfully at home, despite the fact that information showing a single capsule can cause torsades. This study is limited by its small sample size, retrospective design, and reliance on incomplete information.

  13. The Galactic Center: A Petaelectronvolt Cosmic-ray Acceleration Factory (United States)

    Guo, Yi-Qing; Tian, Zhen; Wang, Zhen; Li, Hai-Jin; Chen, Tian-Lu


    The multiteraelectronvolt γ-rays from the galactic center (GC) have a cutoff at tens of teraelectronvolts, whereas the diffuse emission has no such cutoff, which is regarded as an indication of petaelectronvolt proton acceleration by the HESS experiment. It is important to understand the inconsistency and study the possibility that petaelectronvolt cosmic-ray acceleration could account for the apparently contradictory point and diffuse γ-ray spectra. In this work, we propose that the cosmic rays are accelerated up to greater than petaelectronvolts in the GC. The interaction between cosmic rays and molecular clouds is responsible for the multiteraelectronvolt γ-ray emissions from both the point and diffuse sources today. Enhanced by the small volume filling factor (VFF) of the clumpy structure, the absorption of the γ-rays leads to a sharp cutoff spectrum at tens of teraelectronvolts produced in the GC. Away from the GC, the VFF grows, and the absorption enhancement becomes negligible. As a result, the spectra of γ-ray emissions for both point and diffuse sources can be successfully reproduced under such a self-consistent picture. In addition, a “surviving tail” at ∼100 TeV is expected from the point source, which can be observed by future projects CTA and LHAASO. Neutrinos are simultaneously produced during proton-proton (PP) collision. With 5–10 years of observations, the KM3Net experiment will be able to detect the petaelectronvolt source according to our calculation.

  14. A person-centered approach to moral judgment. (United States)

    Uhlmann, Eric Luis; Pizarro, David A; Diermeier, Daniel


    Both normative theories of ethics in philosophy and contemporary models of moral judgment in psychology have focused almost exclusively on the permissibility of acts, in particular whether acts should be judged on the basis of their material outcomes (consequentialist ethics) or on the basis of rules, duties, and obligations (deontological ethics). However, a longstanding third perspective on morality, virtue ethics, may offer a richer descriptive account of a wide range of lay moral judgments. Building on this ethical tradition, we offer a person-centered account of moral judgment, which focuses on individuals as the unit of analysis for moral evaluations rather than on acts. Because social perceivers are fundamentally motivated to acquire information about the moral character of others, features of an act that seem most informative of character often hold more weight than either the consequences of the act or whether a moral rule has been broken. This approach, we argue, can account for numerous empirical findings that are either not predicted by current theories of moral psychology or are simply categorized as biases or irrational quirks in the way individuals make moral judgments.

  16. Pediatric Mortality in a Rural Tertiary Care Center in Liberia (United States)

    Tsai, Carmelle; Walters, Camila B.; Sampson, John; Kateh, Francis; Chang, Mary P.


    Liberia is a low-income country in West Africa that has faced significant challenges, including a civil war and the recent Ebola epidemic. Little data exists on the more current post-war and pre-Ebola trends of child health in Liberia in the rural setting. This study is a retrospective chart review of pediatric mortality in 2013 at a rural tertiary care center in Liberia, 10 years post-war. From January 2013 to December 2013, there were 50 pediatric deaths, or 5.4% of the 920 total pediatric admissions. The most common cause of neonatal death was sepsis, and the most common cause of death under five years of age was malaria. The majority (82.0%) of the deaths were in children under five. Pediatric mortality at this hospital was similar to other reported mortality six years post-war, and lower than that reported immediately post-war. Neonatal sepsis and malaria are two significant causes of pediatric mortality in this community and, therefore, further efforts to decrease childhood mortality should focus on these causes. PMID:28146099

  17. Facial rehabilitation: a neuromuscular reeducation, patient-centered approach. (United States)

    Vanswearingen, Jessie


    Individuals with facial paralysis and distorted facial expressions and movements secondary to a facial neuromotor disorder experience substantial physical, psychological, and social disability. Previously, facial rehabilitation has not been widely available or considered to be of much benefit. An emerging rehabilitation science of neuromuscular reeducation and evidence for the efficacy of facial neuromuscular reeducation, a process of facilitating the return of intended facial movement patterns and eliminating unwanted patterns of facial movement and expression, may provide patients with disorders of facial paralysis or facial movement control opportunity for the recovery of facial movement and function. We provide a brief overview of the scientific rationale for facial neuromuscular reeducation in the structure and function of the facial neuromotor system, the neuropsychology of facial expression, and relations among expressions, movement, and emotion. The primary purpose is to describe principles of neuromuscular reeducation, assessment and outcome measures, approach to treatment, the process, including surface-electromyographic biofeedback as an adjunct to reeducation, and the goal of enhancing the recovery of facial expression and function in a patient-centered approach to facial rehabilitation.

  18. Naturalistic Cognition: A Research Paradigm for Human-Centered Design

    Directory of Open Access Journals (Sweden)

    Peter Storkerson


    Full Text Available Naturalistic thinking and knowing, the tacit, experiential, and intuitive reasoning of everyday interaction, have long been regarded as inferior to formal reason and labeled primitive, fallible, subjective, superstitious, and in some cases ineffable. But, naturalistic thinking is more rational and definable than it appears. It is also relevant to design. Inquiry into the mechanisms of naturalistic thinking and knowledge can bring its resources into focus and enable designers to create better, human-centered designs for use in real-world settings. This article makes a case for the explicit, formal study of implicit, naturalistic thinking within the fields of design. It develops a framework for defining and studying naturalistic thinking and knowledge, for integrating them into design research and practice, and for developing a more integrated, consistent theory of knowledge in design. It will (a outline historical definitions of knowledge, attitudes toward formal and naturalistic thinking, and the difficulties presented by the co-presence of formal and naturalistic thinking in design, (b define and contrast formal and naturalistic thinking as two distinct human cognitive systems, (c demonstrate the importance of naturalistic cognition in formal thinking and real-world judgment, (d demonstrate methods for researching naturalistic thinking that can be of use in design, and (e briefly discuss the impact on design theory of admitting naturalistic thinking as valid, systematic, and knowable.

  19. Penile lichen sclerosus: An urologist's nightmare! - A single center experience (United States)

    Singh, Jitendra Pratap; Priyadarshi, Vinod; Goel, Hemant Kumar; Vijay, Mukesh Kumar; Pal, Dilip Kumar; Chakraborty, Sudip; Kundu, Anup Kumar


    Purpose: Penile lichen sclerosus (LS) is a nagging condition and its progression result in devastating urinary and sexual problems and reduction in the quality-of-life. This study has been carried out to present our experience about this disease with simultaneous review of the available literature. Materials and Methods: This retrospective study has been done at a tertiary care center of eastern India. The data of 306 patients affected with LS were analyzed for clinical presentation, physical examination, investigations, and treatment offered. Results: Presenting symptoms were non-specific. The prepuce was most commonly involved location followed by glans and meatus. Urethral involvement was not isolated as the primary site. Circumcision was done in 237 patients, while 63 patients underwent meatotomy. Thirty-six of 39 cases of LS induced stricture were treated with buccal mucosal graft (BMG) either in one stage or in two stages. Conclusion: LS varies from being a highly aggressive disease of the penis and anterior urethra to a burnt out condition affecting just the meatus and surrounding glans. Early diagnosis and treatment are required to prevent its complication and associated morbidity. Management depends on the anatomical location of lesion, extent of involvement, rapidity of progression and its severity. Use of BMG in LS induced urethral stricture has shown encouraging results.

  6. Cerebral mycosis: 7-year retrospective series in a tertiary center. (United States)

    Raparia, Kirtee; Powell, Suzanne Z; Cernoch, Pat; Takei, Hidehiro


    This study focuses on the epidemiology, clinical manifestations, risk factors, diagnosis and outcome of all cases of central nervous system (CNS) fungal infections in a tertiary center. Medical records of 18 patients of culture-proven CNS fungal infections were retrospectively reviewed from 2000 to 2007, including 12 isolated from the cerebrospinal fluid (CSF) and seven from tissue biopsy. Patient demographic data included 10 males and eight females. The mean age was 55 years (range: 24-89 years). All but one patient were immunocompromised. Fungal organisms isolated from CSF included: Cryptococcous neoformans (8 patients), Coccidioides immitis (3 patients), and Aspergillus versicolor (1 patient). Histopathology of seven biopsy cases revealed groups of pigmented golden-brown fungal forms in three cases; three cases showed septate fungi, two of which had melanin in their walls; and one case showed multiple round spherules. These cases on microbiological cultures grew Coccidioides immitis (1 patient), Aspergillus fumigatus (1 patient), Cladophialophora bantiana (2 patients), Fonsecaea monophora (1 patient) and Scedosporium apiospermum (2 patients). Five of the seven fungal organisms isolated from tissue biopsies were dematiaceous fungi. Twelve patients died after a period of a few weeks to months, two were lost to follow-up, and four are alive with severe neurological sequelae. CNS fungal infections in our cohort were more common in patients post-transplant and with hematologic malignancies. In our series, rare dematiaceous fungi are emerging agents for cerebral mycosis. The outcome of CNS fungal infections is poor despite vigorous antifungal therapy.

  7. Postpercutaneous Nephrolithotomy Nephrostogram: Is It Mandatory? A Single Center Experience

    Directory of Open Access Journals (Sweden)

    Abdul Rouf Khawaja


    Full Text Available Aims and Objective. “Postpercutaneous nephrolithotomy nephrostogram” (PPNN is routinely performed in most of the centers. No published series could be found in the literature without post percutaneous nephrolithotomy nephrostogram. Hence, the aim of our study is to highlight that post percutaneous nephrolithotomy nephrostogram is not mandatory and it only adds to cost and morbidity without adding any information in the management of such patients. Methods. It was a prospective study from 2005 to 2012, conducted in our institute. It included 119 patients of renal stones who underwent percutaneous nephrolithotomy performed under the guidance of a single surgeon. Postoperative nephrostogram was not done in any of the patients. Results. Complete stone clearance was achieved in 97.5% of patients and 2.5% of patients needed two to three sessions of ESWL later on. None of the patients needed second look percutaneous nephrolithotomy or nephrostogram. Conclusion. Postpercutaneous nephrolithotomy nephrostogram increases chances of infection, inconvenience, contrast related complications, and cost, with no added advantage over plain X-ray KUB, and it should not be done as a routine investigation prior to the removal of PCN tube in patients with complete stone clearance.

  8. From STEM to STEAM: Toward a Human-Centered Education (United States)

    Boy, Guy A.


    The 20th century was based on local linear engineering of complicated systems. We made cars, airplanes and chemical plants for example. The 21st century has opened a new basis for holistic non-linear design of complex systems, such as the Internet, air traffic management and nanotechnologies. Complexity, interconnectivity, interaction and communication are major attributes of our evolving society. But, more interestingly, we have started to understand that chaos theories may be more important than reductionism, to better understand and thrive on our planet. Systems need to be investigated and tested as wholes, which requires a cross-disciplinary approach and new conceptual principles and tools. Consequently, schools cannot continue to teach isolated disciplines based on simple reductionism. Science; Technology, Engineering, and Mathematics (STEM) should be integrated together with the Arts1 to promote creativity together with rationalization, and move to STEAM (with an "A" for Arts). This new concept emphasizes the possibility of longer-term socio-technical futures instead of short-term financial predictions that currently lead to uncontrolled economies. Human-centered design (HCD) can contribute to improving STEAM education technologies, systems and practices. HCD not only provides tools and techniques to build useful and usable things, but also an integrated approach to learning by doing, expressing and critiquing, exploring possible futures, and understanding complex systems.

  9. A Kennedy Space Center implementation of IEEE 1451 (United States)

    Oostdyk, Rebecca L.; Mata, Carlos T.; Perotti, José M.; Lucena, Angel R.; Mullenix, Pamela A.


    To meet the demand for more reliable sensory data, longer sensor calibration cycles, and more useful information for operators at NASA's Kennedy Space Center (KSC), NASA's Instrumentation Branch and ASRC's Advanced Electronics and Technology Development Laboratory at the KSC are developing custom intelligent sensors based on the IEEE 1451 family of smart-sensor standards. The KSC intelligent sensors are known as Smart Networked Elements (SNEs), and each SNE includes transducers and their associated Transducer Electronic Data Sheets (TEDS), signal conditioning, analog-to-digital conversion, software algorithms for performing health checks on the data, and a network connection for sending data to other SNEs and higher-level systems. The development of the SNE has led to the definition of custom architectures, protocols, IEEE 1451 implementations, and TEDS, which are presented in this paper. The IEEE 1451 standards describe the architecture, message formats, software objects, and communication protocols within the smart sensor. Because of the standard's complexity, KSC has simplified the IEEE 1451 architecture and narrowed the scope of software objects to be included in the SNE to create a "light" IEEE 1451 implementation, and has used the manufacturer-defined TEDS to customize the SNE with health indicators. Furthermore, KSC has developed a protocol that allows the SNEs to communicate over an Ethernet network while reducing bandwidth requirements.

    Katsulis, Zachary; Ergai, Awatef; Leung, Wai Yin; Schenkel, Laura; Rai, Amisha; Adelman, Jason; Benneyan, James; Bates, David W; Dykes, Patricia C


    Due to the large number of falls that occur in hospital settings, inpatient fall prevention is a topic of great interest to patients and health care providers. The use of electronic decision support that tailors fall prevention strategy to patient-specific risk factors, known as Fall T.I.P.S (Tailoring Interventions for Patient Safety), has proven to be an effective approach for decreasing hospital falls. A paper version of the Fall T.I.P.S toolkit was developed primarily for hospitals that do not have the resources to implement the electronic solution; however, more work is needed to optimize the effectiveness of the paper version of this tool. We examined the use of human factors techniques in the redesign of the existing paper fall prevention tool with the goal of increasing ease of use and decreasing inpatient falls. The inclusion of patients and clinical staff in the redesign of the existing tool was done to increase adoption of the tool and fall prevention best practices. The redesigned paper Fall T.I.P.S toolkit showcased a built in clinical decision support system and increased ease of use over the existing version.

    The National Center for Biotechnology Information's (NCBI) Gene database ( integrates gene-specific information from multiple data sources. NCBI Reference Sequence (RefSeq) genomes for viruses, prokaryotes and eukaryotes are the primary foundation for Gene records in that they form the critical association between sequence and a tracked gene upon which additional functional and descriptive content is anchored. Additional content is integrated based on the genomic location and RefSeq transcript and protein sequence data. The content of a Gene record represents the integration of curation and automated processing from RefSeq, collaborating model organism databases, consortia such as Gene Ontology, and other databases within NCBI. Records in Gene are assigned unique, tracked integers as identifiers. The content (citations, nomenclature, genomic location, gene products and their attributes, phenotypes, sequences, interactions, variation details, maps, expression, homologs, protein domains and external databases) is available via interactive browsing through NCBI's Entrez system, via NCBI's Entrez programming utilities (E-Utilities and Entrez Direct) and for bulk transfer by FTP.

  12. Current State of Agile User-Centered Design: A Survey (United States)

    Hussain, Zahid; Slany, Wolfgang; Holzinger, Andreas

    Agile software development methods are quite popular nowadays and are being adopted at an increasing rate in the industry every year. However, these methods are still lacking usability awareness in their development lifecycle, and the integration of usability/User-Centered Design (UCD) into agile methods is not adequately addressed. This paper presents the preliminary results of a recently conducted online survey regarding the current state of the integration of agile methods and usability/UCD. A world wide response of 92 practitioners was received. The results show that the majority of practitioners perceive that the integration of agile methods with usability/UCD has added value to their adopted processes and to their teams; has resulted in the improvement of usability and quality of the product developed; and has increased the satisfaction of the end-users of the product developed. The top most used HCI techniques are low-fidelity prototyping, conceptual designs, observational studies of users, usability expert evaluations, field studies, personas, rapid iterative testing, and laboratory usability testing.

    Full Text Available Background. Stroke mortality in Brazil is one of the highest among Western countries. Nonetheless, stroke outcome determinants are still poorly known in this country. In this study we evaluate outcome determinants of stroke in a primary stroke center in São Paulo, Brazil. Methods. We evaluated demographic, clinical, and outcome data of patients with ischemic stroke (IS, transient ischemic attack (TIA, and intracerebral hemorrhage (ICH admitted at “Hospital Paulistano,” São Paulo, Brazil. In-hospital mortality and functional outcome determinants were assessed. Univariate and binary logistic regression analysis were performed. Results. Three hundred forty-one patients were included in the study, 52.2% being male with 66.8±15.7 years. The stroke type distribution was IS: 59.2%, TIA: 29.6%, and ICH: 11.1%. ICH was associated with greater severity and poorer functional outcome. The determinants of poorer functional outcome were higher NIHSS, lower Glasgow score, and lower oxygen saturation level. The most important mortality determinant was the presence of visual symptoms. Conclusions. The stroke mortality and stroke outcome determinants found in the present study do not remarkably differ from studies carried out in developed countries. Stroke prognosis studies are crucial to better understand the high burden of stroke in Brazil.

    Raheem OA, Kamel MH, Daly PJ, Mohan P, Little DM, Awan A, Hickey DP. Mycophenolate mofetil in pediatric renal transplantation: A single center experience. Pediatr Transplantation 2011: 15:240-244. © 2009 John Wiley & Sons A\\/S. Abstract:  We assessed our long-term experience with regards to the safety and efficacy of MMF in our pediatric renal transplant population and compared it retrospectively to our previous non-MMF immunosuppressive regimen. Forty-seven pediatric renal transplants received MMF as part of their immunosuppressive protocol in the period from January 1997 till October 2006 (MMF group). A previously reported non-MMF group of 59 pediatric renal transplants was included for comparative analysis (non-MMF group). The MMF group comprised 29 boys and 18 girls, whereas the non-MMF group comprised 34 boys and 25 girls. Mean age was 11.7 and 12 yr in the MMF and non-MMF groups, respectively. The incidence of acute rejection episodes was 11 (23.4%) and 14 (24%) in the MMF and non-MMF group, respectively. Two (3.3%) grafts were lost in the non-MMF group compared with one (2.1%) in the MMF group. Twenty-one (44.68%) patients in the MMF group developed post-transplant infections compared with 12 (20.33%) in the non-MMF group (p < 0.0001). In conclusion, the use of MMF in pediatric renal transplantation was not associated with a lower rejection rate or immunological graft loss. It did, however, result in a significantly higher rate of viral infections.

  18. A project-centered undergraduate geoscience curriculum model (United States)

    Kelso, P.; Brown, L.


    Lake Superior State University, a comprehensive rural public university with approximately 10% Native-Americans enrolled, located in Michigan's eastern Upper Peninsula, U.S.A., has redesigned it's undergraduate geology major by developing an entire curriculum around a project-centered integration of geoscience sub-disciplines. Our model, adapted from modern educational theory, advocates sub-discipline integration by implementing problem-based learning through coursework that develops students' intellectual skills and engages them in using complex reasoning in real-world contexts. Students in this new curriculum will actively discover how to learn about a new geologic province, what questions to ask in approaching problems, where and how to find answers, and how to apply knowledge to solving problems. To accomplish our goals, we redesigned our pedagogy for all courses by creating active learning environments including cooperative learning, jigsaw methodologies, debates, investigation oriented laboratories, use of case studies, writing and communication intensive exercises, and research experiences. Fundamental sub-discipline concepts were identified by our national survey and are presented in the context of sequentially ordered problems that reflect increasing geological complexity. All courses above first year incorporate significant field experience. Our lower division courses include a two semester sequence of physical and historical geology in which physical processes are discussed in the context of their historical extension and one semester of structure/tectonics and mineralogy/petrology. The lower division culminates with a three week introductory field geology course. Our upper division courses include hydrologic systems, environmental systems, geochemical systems, tectonic systems, geophysical systems, clastic systems, carbonate systems, two seminar courses, and advanced field geology. The two field courses, offered in different geologic provinces, provide

    In recent years, efficient energy utilization becomes an essential requirement for data centers, especially in data centers of world-leading companies, where "Green Data Center" defines a new term for an environment-concerned data center. Solutions to change existing a data center to the green one may vary. In the big company, high-cost approaches including re-planning server rooms, changing air-conditioners, buying low-powered servers, and equipping sophisticating environmental control equipments are possible, but not for small to medium enterprises (SMEs) and academic sectors which have limited budget. In this paper, we propose a novel system, SENVM, used to monitor and control air temperature in a server room to be in appropriate condition, not too cold, where very unnecessary cooling leads to unnecessary extra electricity expenses, and also inefficient in energy utilization. With implementing on an emerging technology, Wireless Sensor Network (WSN), Green Data Center is feasible to every small data center...

  20. Transplant center quality assessment using a continuously updatable, risk-adjusted technique (CUSUM). (United States)

    Axelrod, D A; Guidinger, M K; Metzger, R A; Wiesner, R H; Webb, R L; Merion, R M


    Access to timely, risk-adjusted measures of transplant center outcomes is crucial for program quality improvement. The cumulative summation technique (CUSUM) has been proposed as a sensitive tool to detect persistent, clinically relevant changes in transplant center performance over time. Scientific Registry of Transplant Recipients data for adult kidney and liver transplants (1/97 to 12/01) were examined using logistic regression models to predict risk of graft failure (kidney) and death (liver) at 1 year. Risk-adjusted CUSUM charts were constructed for each center and compared with results from the semi-annual method of the Organ Procurement and Transplantation Network (OPTN). Transplant centers (N = 258) performed 59 650 kidney transplants, with a 9.2% 1-year graft failure rate. The CUSUM method identified centers with a period of significantly improving (N = 92) or declining (N = 52) performance. Transplant centers (N = 114) performed 18 277 liver transplants, with a 13.9% 1-year mortality rate. The CUSUM method demonstrated improving performance at 48 centers and declining performance at 24 centers. The CUSUM technique also identified the majority of centers flagged by the current OPTN method (20/22 kidney and 8/11 liver). CUSUM monitoring may be a useful technique for quality improvement, allowing center directors to identify clinically important, risk-adjusted changes in transplant center outcome.

    Full Text Available Introduction: Occupational exposure to Hepatitis B virus (HBV, human immunodeficiency virus (HIV and Hepatitis C virus (HCV infection is a cause of concern to all health care workers (HCWs, especially those, in hospitals. Among the HCWs, nurses, interns, technicians, resident doctors and housekeeping staff have the highest incidence of occupational exposure. Aims: To analyze the cases of needle stick injuries and other exposures to patient′s blood or body fluids among health care workers. Materials and Methods: A detailed account of the exposure is documented which includes incidence of needle stick injuries (NSI and implementation of post-exposure prophylaxis (PEP as per the hospital guidelines. We report a two-year continuing surveillance study where 255 health care workers (HCWs were included. PEP was given to HCWs sustaining NSI or exposures to blood and body fluids when the source is known sero-positive or even unknown where the risk of transmission is high. Follow-up of these HCW′s was done after three and six months of exposure. Results: Of the 255 HCWs, 59 sustained needle stick injuries and two were exposed to splashes. 31 of the NSI were from known sources and 28 from unknown sources. From known sources, thirteen were seropositive; seven for HIV, three for HCV and three for HBV. Nineteen of them sustained needle stick during needle re-capping, six of them during clean up, six of them while discarding into the container, 17 during administration of injection, eight of them during suturing, two occurred in restless patient, 17 during needle disposal. Conclusion: So far, no case of sero-conversion as a result of needle stick injuries was reported at our center.

  7. Complementary and Alternative Medicine Use at a Comprehensive Cancer Center. (United States)

    Luo, Qianlai; Asher, Gary N


    Background Complementary and alternative medicine (CAM) use is common among cancer patients, but the majority of CAM studies do not specify the time periods in relation to cancer diagnoses. We sought to define CAM use by cancer patients and investigate factors that might influence changes in CAM use in relation to cancer diagnoses. Methods We conducted a cross-sectional survey of adults diagnosed with breast, prostate, lung, or colorectal cancer between 2010 and 2012 at the Lineberger Comprehensive Cancer Center. Questionnaires were sent to 1794 patients. Phone calls were made to nonrespondents. Log binomial/Poisson regressions were used to investigate the association between cancer-related changes in CAM use and conversations about CAM use with oncology providers. Results We received 603 (33.6 %) completed questionnaires. The mean age (SD) was 64 (11) years; 62% were female; 79% were white; and 98% were non-Hispanic. Respondents reported the following cancer types: breast (47%), prostate (27%), colorectal (14%), lung (11%). Eighty-nine percent reported lifetime CAM use. Eighty-five percent reported CAM use during or after initial cancer treatment, with category-specific use as follows: mind-body medicine 39%, dietary supplements 73%, body-based therapies 30%, and energy medicine 49%. During treatment CAM use decreased for all categories except energy medicine. After treatment CAM use returned to pretreatment levels for most CAMs except chiropractic. Initiation of CAM use after cancer diagnosis was positively associated with a patient having a conversation about CAM use with their oncology provider, mainly driven by patient-initiated conversations. Conclusions Consistent with previous studies, CAM use was common among our study population. Conversations about CAM use with oncology providers appeared to influence cessation of mind-body medicine use after cancer diagnosis.

  8. Discovery of the recombining plasma in the south of the Galactic center; a relic of the past Galactic center activity?

    Nakashima, S; Uchida, H; Tanaka, T; Tsuru, T G; Koyama, K; Murakami, H; Uchiyama, H


    We report Suzaku results for soft X-ray emission to the south of the Galactic center (GC). The emission (hereafter "GC South") has an angular size of ~42' x 16' centered at (l, b) ~ (0.0, -1.4), and is located in the largely extended Galactic ridge X-ray emission (GRXE). The X-ray spectrum of GC South exhibits emission lines from highly ionized atoms. Although the X-ray spectrum of the GRXE can be well fitted with a plasma in collisional ionization equilibrium (CIE), that of GC South cannot be fitted with a plasma in CIE, leaving hump-like residuals at ~2.5 and 3.5 keV, which are attributable to the radiative recombination continua of the K-shells of Si and S, respectively. In fact, GC South spectrum is well fitted with a recombination-dominant plasma model; the electron temperature is 0.46 keV while atoms are highly ionized (kT = 1.6 keV) in the initial epoch, and the plasma is now in a recombining phase at a relaxation scale (plasma density x elapsed time) of 5.3 x 10^11 s cm^-3. The absorption column densi...

  9. On modeling center of foot pressure distortion through a medium. (United States)

    Betker, Aimee L; Moussavi, Zahra M K; Szturm, Tony


    The center of foot pressure (COP) is a commonly used output measure of the postural control system as it is indicative of the systems stability. A dense piece of foam, i.e., a sponge, can be used to emulate random environmental conditions that distort the ground reaction forces received and interpreted by the cutaneous sensors in the feet; thus introducing uncertainty into the control system. In this paper, the density and size of the sponge was selected such that a subject's weight did not cause full compression. In general, the COP is measured from the bottom of the sponge. As the sponge is used to distort ground reaction forces, it is reasonable then to assume that the COP signal would also be distorted. The use of other sensory information to identify state of balance, and compute necessary balance adjustments, is therefore required. In addition to a sponge, many different types of specialized footwear and inserts are used for people with peripheral neuropathy, such as diabetics. However, it is difficult to design diabetic footwear without a better understanding of the mechanical and physiological effects that different surfaces typical of outdoor terrains, such as a sponge, which cannot be predicted without the sense of the foot, have on balance. Therefore, the goal of this study was to investigate the change of the COP signal from the top and bottom of the sponge. Portable force sensing mats from Vista Medical were used to obtain the COP from the top and bottom of the sponge. The COP measured on the bottom of the sponge is not the same as the COP measured on the top, particularly in the medial-lateral direction. Several linear and nonlinear models were used to identify the unknown plant; i.e., the sponge. Overall, the nonlinear neural network method had superior performance when compared with the linear models. Thus, the results indicate that the signals from the top and bottom of the sponge are in fact different, and furthermore, they are nonlinearly related

  11. A domain model of a clinical reading center - Design and implementation. (United States)

    Lotz, Gunnar; Peters, Tobias; Zrenner, Eberhart; Wilke, Robert


    In clinical trials huge amounts of raw data are generated. Often these data are submitted to reading centers for being analyzed by experts of that particular type of examination. Although the installment of a reading center can raise the overall quality, they also introduce additional complexity to the management and conduction of a clinical trial. Software can help to handle this complexity. Domain-driven-design is one concept to tackle software development in such complex domains. Here we present our domain model for a clinical reading center, as well as its actual implementation utilizing the Nuxeo enterprise content management system.

    Heffington, Warren M.; Eggebrecht, James A.


    This project benefited the public by assisting manufacturing plants in the United States to save costly energy resources and become more profitable. Energy equivalent to over 75,000 barrels of oil was conserved. The Texas A&M University Industrial Assessment Center (IAC) visited 96 manufacturing plants and spent 101 days in those plants during the contract period from August 9, 2002, through November 30, 2006. Recommended annual energy savings for manufacturers were 37,400,000 kWh (127,600 MMBtu—site basis) of electricity and 309,000 MCF (309,000 MMBtu) of natural gas. Each manufacturer subsequently was surveyed, and based on these surveys reportedly implemented 79% of the electricity savings and 36% of the natural gas savings for an overall energy savings of 48% of recommended. Almost 800 (798) projects were recommended to manufacturers, and they accomplished two-thirds of the projects. Cost savings recommended were $12.3 million and implemented savings were $5.7 million or 47%. During the contract period our average time between site visit and report submittal averaged 46 days; and decreased from 48 days in 2003 to 44 days in 2006. Serving clients well and promptly has been a priority. We visited five ESA overflow clients during FY 06. The Texas A&M University IAC pioneered the presentation of air pollution information in reports, and includes NOx and CO2 reductions due to energy savings in all reports. We also experimented with formal PowerPoint BestPractices presentations called Lunchtime/Showtime in each plant and with delivering electronic versions of the report. During the period of the contract, the director served on the Texas Industries of the Future (IOF) Refining and Chemicals Committee, which oversaw the showcases in 2003 and 2006. The assistant director was the Executive Director of the International Energy Technology Conference held annually. The director and assistant director became qualified specialists in the Process Heating Assessment Scoping

    This article reviews literature about simulation systems for training in healthcare regarding the prevalence of human-centered approaches in the design and development of these systems, motivated by a tradition in this field of working technology-centered. The results show that the focus on human needs and context of use is limited. It is argued that a reduction of the focus on technical advancements in favor of the needs of the users and the healthcare community, underpinned by human factors and ergonomics theory, is favorable. Due to the low number of identified articles describing or discussing human-centered approaches it is furthermore concluded that the publication culture promotes technical descriptions and summative evaluations rather than descriptions and reflections regarding the design and development processes. Shifting the focus from a technology-centered approach to a human-centered one can aid in the process of creating simulation systems for training in healthcare that are: 1) relevant to the learning objectives, 2) adapted to the needs of users, context and task, and 3) not selected based on technical or fidelity criteria.

  19. A framework for clinical teaching: A passion-centered philosophy. (United States)

    Spurr, Shelley; Bally, Jill; Ferguson, Linda


    Clinical nurse educators are facing a number of new challenges in pediatric acute care settings that necessitate revisions to their teaching approaches. In this paper, we present a theoretical discussion of a philosophy of nursing education based on a passion for teaching that, when implemented by clinical nursing faculty, promotes positive learning environments in which nursing students feel supported, valued, and engaged. A revised leadership framework, as originally set out by Day (2004), is utilized to explore the essential philosophical underpinnings of passion that nurse educators may consider as they seek to promote positive student outcomes in clinical nursing education. Beatty et al. (2009) argued that there is a growing conviction that every teacher needs a carefully formulated teaching philosophy. Similarly, we contend that all clinical nurse educators critically evaluate their understanding of the meanings and experiences that motivate and frame their values of teaching. We suggest that teaching with passion promotes the development of a positive learning environment and lends itself to rewarding and successful learning experiences.

    We report Suzaku results for soft X-ray emission to the south of the Galactic center (GC). The emission (hereafter {sup G}C South{sup )} has an angular size of {approx}42' Multiplication-Sign 16' centered at (l, b) {approx} (0. Degree-Sign 0, - 1. Degree-Sign 4) and is located in the largely extended Galactic ridge X-ray emission (GRXE). The X-ray spectrum of GC South exhibits emission lines from highly ionized atoms. Although the X-ray spectrum of the GRXE can be well fitted with a plasma in collisional ionization equilibrium (CIE), that of GC South cannot be fitted with a plasma in CIE, leaving hump-like residuals at {approx}2.5 and 3.5 keV, which are attributable to the radiative recombination continua of the K-shells of Si and S, respectively. In fact, GC South spectrum is well fitted with a recombination-dominant plasma model; the electron temperature is 0.46 keV while atoms are highly ionized (kT = 1.6 keV) in the initial epoch, and the plasma is now in a recombining phase at a relaxation scale (plasma density Multiplication-Sign elapsed time) of 5.3 Multiplication-Sign 10{sup 11} s cm{sup -3}. The absorption column density of GC South is consistent with that toward the GC region. Thus, GC South is likely to be located in the GC region ({approx}8 kpc distance). The size of the plasma, the mean density, and the thermal energy are estimated to be {approx}97 pc Multiplication-Sign 37 pc, 0.16 cm{sup -3}, and 1.6 Multiplication-Sign 10{sup 51} erg, respectively. We discuss possible origins of the recombination-dominant plasma as a relic of past activity in the GC region.

  3. A Novel Approach for Submission of Tasks to a Data Center in a Virtualized Cloud Computing Environment

    Directory of Open Access Journals (Sweden)

    B. Santhosh Kumar


    Full Text Available The submission of tasks to a data center plays a crucial role to achieve the services like scheduling, processing in a cloud computing environment. Energy consumption of a data center must be considered for task processing as it results in high operational expenditures and bad environmental impact. Unfortunately, none of the current research works focus on energy factor while submitting tasks to a cloud. In this paper a framework is proposed to select a data center with minimum energy consumption. The service provider has to register all the data centers in a registry. The energy consumed by task processing using virtualization and energy of IT equipments like routers, switches is calculated. The data center selection framework finally selects the data center with minimum energy consumption for task processing. The experimental results indicate that the proposed idea results in a less energy when compared to the existing algorithms for selection of data centers.

  6. Implementing a Student-Centered Pedagogy: Doing so in the Indonesian Teaching-Learning Context

    Directory of Open Access Journals (Sweden)

    Hanung Triyoko


    Full Text Available Today’s educators must be willing to shift from the teacher-centered paradigm, which was in place when they themselves were students, to the new paradigm of student-centered education. This article was inspired by the challenges and opportunities experienced by the writers while attempting to  implement a student-centered pedagogy. We will share some of our experiences as educators to provide a context for various aspects of student centered-learning.  Understanding some of the successes and failures we have experienced in our careers may help to highlight the potential and importance of student-centered pedagogy in its many facets. Based on the vignettes from our teaching experiences, we have identified four major ideas about how to adopt a more student-centered approach: planning lessons that encourage student interest; adapting the curriculum to meet student’s needs; using technology in the classroom; and developing mutually respectful relationships.

  7. Location selection criteria for a second data center or off-site storage of materials. (United States)

    Cochran, Mitchell; Witman, Paul


    As organizations develop secondary data centers, it is critical that they be placed in locations that serve the organization yet do not have a shared risk with the primary data center. The organization needs to consider factors or guidelines which mitigate potential issues that could affect both the primary and secondary data center. It is impossible to eliminate all risk to a single data center but an organization needs to ensure that at least one data center remains operable. The article will propose that data centers be located 50 km or approximately 30 miles apart. The proposal is supported by evaluating earthquake intensity maps that will show that earthquakes damage drops to relatively safe levels after the 30 miles from the epicenter. The article will show that other environmental factors such as power, floods, fire, transportation, fire, and soil are also mitigated by a 30-mile separation guideline.

  8. Beyond active learning: a case study of teaching practices in an occupation-centered curriculum. (United States)

    Hooper, Barbara


    Although occupation-centered curricula are highly promoted, the teaching processes that convey such designs remain unclear. This case study elucidated occupation-centered teaching practices. Interview and observational data were collected over 8 weeks, and analysis involved coding transcriptions, data matrices, concept maps, journaling, and writing. Participants augmented active learning strategies with strategies that linked course topics to the subject of occupation. The use of linking strategies suggested that: (a) course content was treated as two-tiered; (b) neither content nor instructional processes were inherently occupation-centered; and (c) subject-centered education strengthens social learning theories. Although curricula may appear occupation-centered based on a curriculum description and course content, ultimately "linking opportunities" in the classroom constitute an essential feature that demarcates a program as occupation-centered.

  16. Information systems performance evaluation, introducing a two-level technique: Case study call centers

    Directory of Open Access Journals (Sweden)

    Hesham A. Baraka


    The objective of this paper was to introduce a new technique that can support decision makers in the call centers industry to evaluate, and analyze the performance of call centers. The technique presented is derived from the research done on measuring the success or failure of information systems. Two models are mainly adopted namely: the Delone and Mclean model first introduced in 1992 and the Design Reality Gap model introduced by Heeks in 2002. Two indices are defined to calculate the performance of the call center; the success index and the Gap Index. An evaluation tool has been developed to allow call centers managers to evaluate the performance of their call centers in a systematic analytical approach; the tool was applied on 4 call centers from different areas, simple applications such as food ordering, marketing, and sales, technical support systems, to more real time services such as the example of emergency control systems. Results showed the importance of using information systems models to evaluate complex systems as call centers. The models used allow identifying the dimensions for the call centers that are facing challenges, together with an identification of the individual indicators in these dimensions that are causing the poor performance of the call center.

    Swan, James H; Severance, Jennifer J; Turner, Keith


    Healthy diet and weight control are important for elders and senior centers (SCs). The authors consider effects of SCs on attendee nutrition and health and efforts to improve diets and weight. Data derive from surveys in 2006 (N = 798) and 2007 (N = 742) at 21 multipurpose SCs in Tarrant County, Texas, supplemented with data from 2012 (N = 1,402). Measures included attendee agreement that SC meals improved nutrition, improved health, attempts to improve diets, and success in controlling weight. Cumulative and binary logistic regression methods were employed. SC attendance and social engagement explained agreement that SC meals improved nutrition and health but were not shown to predict changes in diet or weight control. Findings suggest success of SC programs, as well as physician recommendations, in influencing attendee nutritional behavior and perceptions of nutrition and health effects. Practice recommendations include SC collaborations with local health providers to promote attendee nutritional health.

    Asgari P


    Full Text Available Background and Objective: One of the major issues in hemodialysis patients is adherence to diet and fluid restriction. In order to reduce the adverse consequences of the disease and improve quality of life, educating these patients is of great importance. Therefore, the present study was conducted in order to compare the impact of two methods of education (patient-centered and family–centered on attitude toward and adherence to diet and fluid restriction in hemodialysis patients. Materials and Method: This clinical trial was performed on patients referred to the hemodialysis ward of hospitals affiliated with Tehran University of Medical Sciences, Iran, during May to October 2012. Through purposive sampling method, 60 patients were selected and randomly assigned to two groups patient-centered (n = 30 and family-centered (n = 30. Patients’ attitude toward and adherence to diet regime and fluid restriction were assessed using a researcher-made self-report questionnaire in 3 stages (before the intervention, and 2 and 4 weeks after the intervention. The reliability and validity of the questionnaire were approved. Data analysis was performed using SPSS software version 16 and independent t-test, chi-square, Fisher’s exact test, and repeated measures ANOVA. Results: Before the intervention, the findings showed no significant difference between the 2 groups in terms of adherence to diet and fluid restriction. In the second week after the intervention, mean adherence to diet in the family-centered group was significantly higher than the patient-centered group (P = 0.010. Moreover, at the end of the second (P = 0.001 and fourth weeks (P = 0.002, the attitude toward adherence to diet and fluid restriction was more positive in the family-centered group, in comparison to the patient-centered group. Conclusion: Family-centered education is more effective on patient adherence to the treatment regimen. Thus, it is recommended that family-centered

The excitation of single plasmonic modes is witnessed and a total rate enhancement by a factor of up to 4...

  14. Perioperative Feeding Approaches in Single Ventricle Infants: A Survey of 46 Centers. (United States)

    Slicker, Julie; Sables-Baus, Sharon; Lambert, Linda M; Peterson, Laura E; Woodard, Frances K; Ocampo, Elena C


    Background Feeding dysfunction occurs commonly in infants with single ventricle heart disease and impacts growth and long-term outcomes. Little evidence exists to guide safe feeding in this population. This study surveyed centers participating in the National Pediatric Cardiology Quality Improvement Collaborative to assess prevailing feeding practices amongthose caring for single ventricle neonates. Methods Web-based survey of 56 pediatric cardiac surgical centers was conducted. Questions addressed peri-operative feeding approaches and responses were presented and analyzed descriptively. Results Of 56 centers, 46 (82%) completed a survey. Preoperative feeding was common in single ventricle infants (30/46; 65%), routes varied. Centers who did not feed infants preoperatively cited the risk of necrotizing enterocolitis (16/16; 100%), presence of umbilical artery catheter (12/16; 75%), and prostaglandin infusion (9/16; 56%) as main concerns. 67% of centers reported no specific vital sign thresholds for withholding enteral feedings. In the postoperative period, most centers used an "internal guideline" (21/46; 46%) or an "informal practice" (15/46; 33%) to determine feeding readiness. Approaches to findings were significantly different among centers. About 40% of centers did not send patients home with feeding tubes, and there was no clear consensus between preferred feeding tube modality at discharge. Conclusion Considerable variation exists in feeding practices for infants with single ventricle congenital heart disease among 46 centers participating in a quality improvement collaborative. Although most centers generally feed infants preoperatively, feeding practices remain center-specific. Variability continues in the immediate post-operative and interstage periods. Further opportunities exist for investigation, standardization and development of best-practice feeding guidelines.

  15. A Proposed Experiment to Study Relaxation Formation of a Spherical Tokamak with a Plasma Center Column

    CERN Document Server

    Hsu, S C


    A spherical tokamak (ST) with a plasma center column (PCC) can be formed via driven magnetic relaxation of a screw pinch plasma. An ST-PCC could in principle eliminate many problems associated with a material center column, a key weakness of the ST reactor concept. This work summarizes the design space for an ST-PCC in terms of flux amplification, aspect ratio, and elongation, based on the zero-beta Taylor-relaxed analysis of Tang & Boozer [Phys. Plasmas 13, 042514 (2006)]. The paper will discuss (1) equilibrium and stability properties of the ST-PCC, (2) issues for an engineering design, and (3) key differences between the proposed ST-PCC and the ongoing Proto-Sphera effort in Italy.

  17. A new approach for laboratory exercise of pathophysiology in China based on student-centered learning. (United States)

    Chen, Jian; Zhou, Junhai; Sun, Li; Wu, Qiuhui; Lu, Huiling; Tian, Jing


    Student-centered learning is generally defined as any instructional method that purportedly engages students in active learning and critical thinking. The student-centered method of teaching moves the focus from teaching to learning, from the teachers' conveying course concepts via lecture to the understanding of concepts by students. The student-centered method has been used extensively in lecture courses in China; however, there is little evidence of its use in laboratory courses. The purpose of the present study was to describe the implementation of a student-centered method in a pathophysiology laboratory course. The use of student-centered learning strategies in an undergraduate laboratory course was well received by both students and teachers. Here, students had to take on responsibility for their own learning and, thus, became more accountable. Moreover, they reported increased active learning, skill development, information collection, and retention. In addition, mean scores for the quiz were significantly higher in the student-centered method compared with the traditional teaching method. The shift from teacher-centered delivery to a student-centered model led to a positive change, in which the learners drove the process and were guided, not directed, by the teacher.

  6. Implementation of a user-centered framework in the development of a web-based health information database and call center. (United States)

    Taylor, Heather A; Sullivan, Dori; Mullen, Cydney; Johnson, Constance M


    As healthcare consumers increasingly turn to the World Wide Web (WWW) to obtain health information, it is imperative that health-related websites are user-centered. Websites are often developed without consideration of intended users' characteristics, literacy levels, preferences, and information goals resulting in user dissatisfaction, abandonment of the website, and ultimately the need for costly redesign. This paper provides a methodological review of a user-centered framework that incorporates best practices in literacy, information quality, and human-computer interface design and evaluation to guide the design and redesign process of a consumer health website. Following the description of the methods, a case analysis is presented, demonstrating the successful application of the model in the redesign of a consumer health information website with call center. Comparisons between the iterative revisions of the website showed improvements in usability, readability, and user satisfaction.

  7. The Galactic Center Molecular Cloud Survey. II. A Lack of Dense Gas & Cloud Evolution along Galactic Center Orbits

    CERN Document Server

    Kauffmann, Jens; Zhang, Qizhou; Menten, Karl M; Goldsmith, Paul F; Lu, Xing; Guzmán, Andrés E; Schmiedeke, Anika


    We present the first systematic study of the density structure of clouds found in a complete sample covering all major molecular clouds in the Central Molecular Zone (CMZ; inner $\\sim{}200~\\rm{}pc$) of the Milky Way. This is made possible by using data from the Galactic Center Molecular Cloud Survey (GCMS), the first study resolving all major molecular clouds in the CMZ at interferometer angular resolution. We find that many CMZ molecular clouds have unusually shallow density gradients compared to regions elsewhere in the Milky Way. This is possibly a consequence of weak gravitational binding of the clouds. The resulting relative absence of dense gas on spatial scales $\\sim{}0.1~\\rm{}pc$ is probably one of the reasons why star formation (SF) in dense gas of the CMZ is suppressed by a factor $\\sim{}10$, compared to solar neighborhood clouds. Another factor suppressing star formation are the high SF density thresholds that likely result from the observed gas kinematics. Further, it is possible but not certain t...

  8. Toward a Caribbean psychology: an African-centered approach. (United States)

    Sutherland, Marcia Elizabeth


    Although the Americas and Caribbean region are purported to comprise different ethnic groups, this article’s focus is on people of African descent, who represent the largest ethnic group in many countries. The emphasis on people of African descent is related to their family structure, ethnic identity, cultural, psychohistorical, and contemporary psychosocial realities. This article discusses the limitations of Western psychology for theory, research, and applied work on people of African descent in the Americas and Caribbean region. In view of the adaptations that some people of African descent have made to slavery, colonialism, and more contemporary forms of cultural intrusions, it is argued that when necessary, notwithstanding Western psychology’s limitations, Caribbean psychologists should reconstruct mainstream psychology to address the psychological needs of these Caribbean people. The relationship between theory and psychological interventions for the optimal development of people of African descent is emphasized throughout this article. In this regard, the African-centered and constructionist viewpoint is argued to be of utility in addressing the psychological growth and development of people of African descent living in the Americas and Caribbean region.

  9. A theory of germinal center B cell selection, division, and exit. (United States)

    Meyer-Hermann, Michael; Mohr, Elodie; Pelletier, Nadége; Zhang, Yang; Victora, Gabriel D; Toellner, Kai-Michael


    High-affinity antibodies are generated in germinal centers in a process involving mutation and selection of B cells. Information processing in germinal center reactions has been investigated in a number of recent experiments. These have revealed cell migration patterns, asymmetric cell divisions, and cell-cell interaction characteristics, used here to develop a theory of germinal center B cell selection, division, and exit (the LEDA model). According to this model, B cells selected by T follicular helper cells on the basis of successful antigen processing always return to the dark zone for asymmetric division, and acquired antigen is inherited by one daughter cell only. Antigen-retaining B cells differentiate to plasma cells and leave the germinal center through the dark zone. This theory has implications for the functioning of germinal centers because compared to previous models, high-affinity antibodies appear one day earlier and the amount of derived plasma cells is considerably larger.

  11. Designing and Implementing a Navicat Database System for a Call Center

    Directory of Open Access Journals (Sweden)

    Thair M. Hamtini


    Full Text Available A call center is a physical place where customer and other telephone calls are handled by an organization, usually with some amount of computer automation. Typically, a call center has the capacity to handle a considerable volume of calls at the same time, to screen calls, forward calls to qualified person to handle them, and to log calls. In this article we proposed an architecture and showed how the system works. Carolina Call Center used to manually keep track of its call information through different programs. Data would be entered on Microsoft Excel and results were displayed on Microsoft Word. This made it hard to keep track of the data in an organized matter. Since many Call Centers may encounter these problems, we found a solution by creating a database. We used Navicat as a database client, and Dreamweaver as a web-interface design. Every agent now had an employee account with a password. Each account gave the agents access to the different campaigns they were working on. The accounts also had a timer as well as a break button that automatically kept track of login, logout and breaks. Not only did the database automate work to the employees, but it was beneficial to be business as well. The decreased number of errors combined with the reduced need for employees helped the call center save money. Since the database is an efficient timesaver, it decreased the number of working hours for both management and employees. The database greatly improved the overall quality of the Carolina Call Center.

  13. Connecting teens to caring adults in a school-based health center: a case study. (United States)

    Blacksin, Beth A; Kelly, Patricia J


    The traditional medical care system is generally unable to provide the broad health and wellness services needed by many adolescents, especially those from low-income and racial/ethnic minority communities. Using a theoretical framework adapted from Bronfenbrenner's ecological model of multiple influencers, this case study examined how a school-based health center was able to provide a network of connections for adolescents to caring adults within the school and the local community. Contributors to this network were the creation of a student-centered community with access to adolescent-friendly services, providers acting as connectors, and care of the whole adolescent.

  14. Quantum Zeno effect in a nitrogen-vacancy center embedded in a spin bath

    CERN Document Server

    Yang, Zhi-Sheng; Zhang, Mei; Ai, Qing; Deng, Fu-Guo


    We study the longitudinal relaxation of a nitrogen-vacancy (NV) center surrounded by a $^{13}$C nuclear spin bath in diamond. By means of cluster-correlation expansion (CCE), we numerically demonstrate the decay process of electronic state induced by cross relaxation at low temperature. It is shown that the CCE method is not only capable of describing pure-dephasing effect at large-detuning regime, but it can also simulate the quantum dynamics of populations in the nearly resonant regime. We present a proposal to slow down the decay of NV center via implementing quantum Zeno effect (QZE). The numerical result shows that QZE can effectively inhibit the decay of NV center.

  15. Normal form and limit cycle bifurcation of piecewise smooth differential systems with a center (United States)

    Wei, Lijun; Zhang, Xiang


    In this paper we prove that any Σ-center (either nondegenerate or degenerate) of a planar piecewise Cr smooth vector field Z is topologically equivalent to that of Z0: (x ˙ , y ˙) = (- 1 , 2 x) for y ≥ 0, (x ˙ , y ˙) = (1 , 2 x) for y ≤ 0, and that the homeomorphism between Z and Z0 is Cr smoothness when restricted to each side of the switching line except at the center p. We illustrate by examples that there are degenerate Σ-centers whose flows are conjugate to that of Z0, and also there exist nondegenerate Σ-centers whose flows cannot be conjugate to that of Z0. Finally applying the normal form Z0 together with the piecewise smooth equivalence, we study the number of limit cycles which can be bifurcated from the Σ-center of Z.

    Cushman, R.M.; Boden, T.A.; Hook, L.A.; Jones, S.B.; Kaiser, D.P.; Nelson, T.R.


    Once again, the most recent fiscal year was a productive one for the Carbon Dioxide Information Analysis Center (CDIAC) at Oak Ridge National Laboratory (ORNL), as well as a year for change. The FY 1998 in Review section in this report summarizes quite a few new and updated data and information products, and the ''What's Coming in FY 1999'' section describes our plans for this new fiscal year. During FY 1998, CDIAC began a data-management system for AmeriFlux, a long-term study of carbon fluxes between the terrestrial biosphere of the Western Hemisphere and the atmosphere. The specific objectives of AmeriFlux are to establish an infrastructure for guiding, collecting, synthesizing, and disseminating long-term measurements of CO{sub 2}, water, and energy exchange from a variety of ecosystems; collect critical new information to help define the current global CO{sub 2} budget; enable improved predictions of future concentrations of atmospheric CO{sub 2}; and enhance understanding of carbon fluxes. Net Ecosystem Production (NEP), and carbon sequestration in the terrestrial biosphere. The data-management system, available from CDIAC'S AmeriFlux home page ( ) is intended to provide consistent, quality-assured, and documented data across all AmeriFlux sites in the US, Canada, Costa Rica, and Brazil. It is being developed by Antoinette Brenkert and Tom Boden, with assistance from Susan Holladay (who joined CDIAC specifically to support the AmeriFlux data-management effort).

  20. Nanoscale fluorescence lifetime imaging of an optical antenna with a single diamond NV center. (United States)

    Beams, Ryan; Smith, Dallas; Johnson, Timothy W; Oh, Sang-Hyun; Novotny, Lukas; Vamivakas, A Nick


    Solid-state quantum emitters, such as artificially engineered quantum dots or naturally occurring defects in solids, are being investigated for applications ranging from quantum information science and optoelectronics to biomedical imaging. Recently, these same systems have also been studied from the perspective of nanoscale metrology. In this letter, we study the near-field optical properties of a diamond nanocrystal hosting a single nitrogen vacancy center. We find that the nitrogen vacancy center is a sensitive probe of the surrounding electromagnetic mode structure. We exploit this sensitivity to demonstrate nanoscale fluorescence lifetime imaging microscopy (FLIM) with a single nitrogen vacancy center by imaging the local density of states of an optical antenna.

  1. Reducing Data Center Loads for a Large-Scale, Net Zero Office Building (Brochure)

    Energy Technology Data Exchange (ETDEWEB)


    Case study highlighting the design, implementation strategies, and continuous performance monitoring of NREL's Research Support Facility data center. In constructing a new research facility for its campus, the National Renewable Energy Laboratory (NREL) project team identified the opportunity to design a world-class, energy-efficient data center to support its operations. NREL's efforts resulted in a highly efficient data center that demonstrated considerable energy savings in its first 11 months of operations. Using legacy data center performance as a baseline, the new facility cut energy use by nearly 1,450,000 kWh, delivering cost savings of approximately $82,000. The data center's average total load was 165 kW less than the legacy center's average total load, resulting in a 60% reduction in overall power. Finally, the limited use of cooling and fan energy enabled the new data center to achieve a 1.16 average power utilization effectiveness (PUE) rating, compared to the legacy data center's PUE of 2.28. The laboratory had been relying on individual servers with an energy utilization rate of less than 5%. NREL employed building best practices, innovative design techniques and energy-efficient technologies to support its energy goals for the new data center. To counteract the extensive heat generated by data center equipment, the laboratory implemented a cooling system using outdoor air and evaporative cooling to meet most of the center's needs. Inside the data center, NREL replaced much of its legacy equipment with new, energy-efficient technology. By exchanging this infrastructure for virtualized blade servers, NREL reduced its server energy footprint by 96%. Additionally, NREL replaced its 80%-efficient uninterruptible power supply (UPS) with a UPS that is 95% efficient; deployed ultra efficient power distribution units (PDU) to handle higher UPS voltages; and implemented vacancy sensors to drive down lighting loads.

  9. Quantitative and qualitative assessment of structural magnetic resonance imaging data in a two-center study

    Directory of Open Access Journals (Sweden)

    Chalavi Sima


    Full Text Available Abstract Background Multi-center magnetic resonance imaging (MRI studies present an opportunity to advance research by pooling data. However, brain measurements derived from MR-images are susceptible to differences in MR-sequence parameters. It is therefore necessary to determine whether there is an interaction between the sequence parameters and the effect of interest, and to minimise any such interaction by careful choice of acquisition parameters. As an exemplar of the issues involved in multi-center studies, we present data from a study in which we aimed to optimize a set of volumetric MRI-protocols to define a protocol giving data that are consistent and reproducible across two centers and over time. Methods Optimization was achieved based on data quality and quantitative measures, in our case using FreeSurfer and Voxel Based Morphometry approaches. Our approach consisted of a series of five comparisons. Firstly, a single-center dataset was collected, using a range of candidate pulse-sequences and parameters chosen on the basis of previous literature. Based on initial results, a number of minor changes were implemented to optimize the pulse-sequences, and a second single-center dataset was collected. FreeSurfer data quality measures were compared between datasets in order to determine the best performing sequence(s, which were taken forward to the next stage of testing. We subsequently acquired short-term and long-term two-center reproducibility data, and quantitative measures were again assessed to determine the protocol with the highest reproducibility across centers. Effects of a scanner software and hardware upgrade on the reproducibility of the protocols at one of the centers were also evaluated. Results Assessing the quality measures from the first two datasets allowed us to define artefact-free protocols, all with high image quality as assessed by FreeSurfer. Comparing the quantitative test and retest measures, we found high within-center

  17. Reducing Data Center Loads for a Large-Scale, Net Zero Office Building

    Energy Technology Data Exchange (ETDEWEB)



    In constructing a new research facility for its campus, the National Renewable Energy Laboratory (NREL) project team identified the opportunity to design a world-class, energy-efficient data center to support its operations. NREL’s efforts resulted in a highly efficient data center that demonstrated considerable energy savings in its first 11 months of operations. Using legacy data center performance as a baseline, the new facility cut energy use by nearly 1,450,000 kWh, delivering cost savings of approximately $82,000. The data center’s average total load was 165 kW less than the legacy center’s average total load, resulting in a 60% reduction in overall power. Finally, the limited use of cooling and fan energy enabled the new data center to achieve a 1.16 average power utilization effectiveness (PUE) rating, compared to the legacy data center’s PUE of 2.28.

[Laboratoire de Simulation Atomistique (L-Sim), SP2M, INAC, CEA-UJF, 38054 Grenoble Cedex 9 (France)


    We investigate the impact of tin doping on the formation of vacancy-oxygen pairs (VO or A-centers) and their conversion to VO{sub 2} clusters in electron-irradiated silicon. The experimental results are consistent with previous reports that Sn doping suppresses the formation of the A-center. We introduce a model to account for the observed differences under both Sn-poor and Sn-rich doping conditions. Using density functional theory calculations, we propose point defect engineering strategies to reduce the concentration of the deleterious A-centers in silicon. We predict that doping with lead, zirconium, or hafnium will lead to the suppression of the A-centers.

  1. Quantum information transfer with nitrogen-vacancy centers coupled to a whispering-gallery microresonator

    CERN Document Server

    Li, Pengbo


    We propose an efficient scheme for the realization of quantum information transfer and entanglement with nitrogen-vacancy (NV) centers coupled to a high-Q microspherical resonator. We show that, based on the effective dipole-dipole interaction between the NV centers mediated by the whispering-gallery mode (WGM), quantum information can be transferred between the NV centers through Raman transitions combined with laser fields. This protocol may open up promising possibilities for quantum communications with the solid state cavity QED system.

  4. Optimizing Patient-centered Communication and Multidisciplinary Care Coordination in Emergency Diagnostic Imaging: A Research Agenda. (United States)

    Sabbatini, Amber K; Merck, Lisa H; Froemming, Adam T; Vaughan, William; Brown, Michael D; Hess, Erik P; Applegate, Kimberly E; Comfere, Nneka I


    Patient-centered emergency diagnostic imaging relies on efficient communication and multispecialty care coordination to ensure optimal imaging utilization. The construct of the emergency diagnostic imaging care coordination cycle with three main phases (pretest, test, and posttest) provides a useful framework to evaluate care coordination in patient-centered emergency diagnostic imaging. This article summarizes findings reached during the patient-centered outcomes session of the 2015 Academic Emergency Medicine consensus conference "Diagnostic Imaging in the Emergency Department: A Research Agenda to Optimize Utilization." The primary objective was to develop a research agenda focused on 1) defining component parts of the emergency diagnostic imaging care coordination process, 2) identifying gaps in communication that affect emergency diagnostic imaging, and 3) defining optimal methods of communication and multidisciplinary care coordination that ensure patient-centered emergency diagnostic imaging. Prioritized research questions provided the framework to define a research agenda for multidisciplinary care coordination in emergency diagnostic imaging.

  7. A Study of Flood Evacuation Center Using GIS and Remote Sensing Technique (United States)

    Mustaffa, A. A.; Rosli, M. F.; Abustan, M. S.; Adib, R.; Rosli, M. I.; Masiri, K.; Saifullizan, B.


    This research demonstrated the use of Remote Sensing technique and GIS to determine the suitability of an evacuation center. This study was conducted in Batu Pahat areas that always hit by a series of flood. The data of Digital Elevation Model (DEM) was obtained by ASTER database that has been used to delineate extract contour line and elevation. Landsat 8 image was used for classification purposes such as land use map. Remote Sensing incorporate with GIS techniques was used to determined the suitability location of the evacuation center from contour map of flood affected areas in Batu Pahat. GIS will calculate the elevation of the area and information about the country of the area, the road access and percentage of the affected area. The flood affected area map may provide the suitability of the flood evacuation center during the several levels of flood. The suitability of evacuation centers can be determined based on several criteria and the existing data of the evacuation center will be analysed. From the analysis among 16 evacuation center listed, there are only 8 evacuation center suitable for the usage during emergency situation. The suitability analysis was based on the location and the road access of the evacuation center toward the flood affected area. There are 10 new locations with suitable criteria of evacuation center proposed on the study area to facilitate the process of rescue and evacuating flood victims to much safer and suitable locations. The results of this study will help in decision making processes and indirectly will help organization such as fire-fighter and the Department of Social Welfare in their work. Thus, this study can contribute more towards the society.

  8. The feasibility of a unified role for NASA regional dissemination centers and technology application teams (United States)


    Insights and recommendations arising from a study of the feasibility of combining the NASA Regional Dissemination Center (RDC) and Technology Application Team (Tateam) roles to form Regional Application Centers (RADC's) are presented. The apparent convergence of the functions of RDC's and Tateams is demonstrated and strongly supportive of the primary recommendation that an applications function be added to those already being performed by the RDC's. The basis of a national network for technology transfer and public and private sector problem solving is shown to exist, the skeleton of which is an interactive network of Regional Application Centers and NASA Field Centers. The feasibility of developing and extending this network is considered and the detailed ramifications of so doing are discussed and the imperatives emphasized. It is hypothesized that such a national network could become relatively independent of NASA funding within five years.

  9. Social influence in child care centers: a test of the theory of normative social behavior. (United States)

    Lapinski, Maria Knight; Anderson, Jenn; Shugart, Alicia; Todd, Ewen


    Child care centers are a unique context for studying communication about the social and personal expectations about health behaviors. The theory of normative social behavior (TNSB; Rimal & Real, 2005 ) provides a framework for testing the role of social and psychological influences on handwashing behaviors among child care workers. A cross-sectional survey of child care workers in 21 centers indicates that outcome expectations and group identity increase the strength of the relationship between descriptive norms and handwashing behavior. Injunctive norms also moderate the effect of descriptive norms on handwashing behavior such that when strong injunctive norms are reported, descriptive norms are positively related to handwashing, but when weak injunctive norms are reported, descriptive norms are negatively related to handwashing. The findings suggest that communication interventions in child care centers can focus on strengthening injunctive norms in order to increase handwashing behaviors in child care centers. The findings also suggest that the theory of normative social behavior can be useful in organizational contexts.

  10. Multiple emotions: a person-centered approach to the relationship between intergroup emotion and action orientation. (United States)

    Fernando, Julian W; Kashima, Yoshihisa; Laham, Simon M


    Although a great deal of research has investigated the relationship between emotions and action orientations, most studies to date have used variable-centered techniques to identify the best emotion predictor(s) of a particular action. Given that people frequently report multiple or blended emotions, a profitable area of research may be to adopt person-centered approaches to examine the action orientations elicited by a particular combination of emotions or "emotion profile." In two studies, across instances of intergroup inequality in Australia and Canada, we examined participants' experiences of six intergroup emotions: sympathy, anger directed at three targets, shame, and pride. In both studies, five groups of participants with similar emotion profiles were identified by cluster analysis and their action orientations were compared; clusters indicated that the majority of participants experienced multiple emotions. Each action orientation was also regressed on the six emotions. There were a number of differences in the results obtained from the person-centered and variable-centered approaches. This was most apparent for sympathy: the group of participants experiencing only sympathy showed little inclination to perform prosocial actions, yet sympathy was a significant predictor of numerous action orientations in regression analyses. These results imply that sympathy may only prompt a desire for action when experienced in combination with other emotions. We suggest that the use of person-centered and variable-centered approaches as complementary analytic strategies may enrich research into not only the affective predictors of action, but emotion research in general.

  12. Audit of a Scientific Data Center for Certification as a Trustworthy Digital Repository: A Case Study (United States)

    Downs, R. R.; Chen, R. S.


    Services that preserve and enable future access to scientific data are necessary to ensure that the data that are being collected today will be available for use by future generations of scientists. Many data centers, archives, and other digital repositories are working to improve their ability to serve as long-term stewards of scientific data. Trust in sustainable data management and preservation capabilities of digital repositories can influence decisions to use these services to deposit or obtain scientific data. Building on the Open Archival Information System (OAIS) Reference Model developed by the Consultative Committee for Space Data Systems (CCSDS) and adopted by the International Organization for Standardization as ISO 14721:2003, new standards are being developed to improve long-term data management processes and documentation. The Draft Information Standard ISO/DIS 16363, "Space data and information transfer systems - Audit and certification of trustworthy digital repositories" offers the potential to evaluate digital repositories objectively in terms of their trustworthiness as long-term stewards of digital resources. In conjunction with this, the CCSDS and ISO are developing another draft standard for the auditing and certification process, ISO/DIS 16919, "Space data and information transfer systems - Requirements for bodies providing audit and certification of candidate trustworthy digital repositories". Six test audits were conducted of scientific data centers and archives in Europe and the United States to test the use of these draft standards and identify potential improvements for the standards and for the participating digital repositories. We present a case study of the test audit conducted on the NASA Socioeconomic Data and Applications Center (SEDAC) and describe the preparation, the audit process, recommendations received, and next steps to obtain certification as a trustworthy digital repository, after approval of the ISO/DIS standards.

    Nahm, Eun-Shim; Diblasi, Catherine; Gonzales, Eva; Silver, Kristi; Zhu, Shijun; Sagherian, Knar; Kongs, Katherine


    Personal health records and patient portals have been shown to be effective in managing chronic illnesses. Despite recent nationwide implementation efforts, the personal health record and patient portal adoption rates among patients are low, and the lack of support for patients using the programs remains a critical gap in most implementation processes. In this study, we implemented the Patient-Centered Personal Health Record and Patient Portal Implementation Toolkit in a large diabetes/endocrinology center and assessed its preliminary impact on personal health record and patient portal knowledge, self-efficacy, patient-provider communication, and adherence to treatment plans. Patient-Centered Personal Health Record and Patient Portal Implementation Toolkit is composed of Patient-Centered Personal Health Record and Patient Portal Implementation Toolkit-General, clinic-level resources for clinicians, staff, and patients, and Patient-Centered Personal Health Record and Patient Portal Implementation Toolkit Plus, an optional 4-week online resource program for patients ("MyHealthPortal"). First, Patient-Centered Personal Health Record and Patient Portal Implementation Toolkit-General was implemented, and all clinicians and staff were educated about the center's personal health record and patient portal. Then general patient education was initiated, while a randomized controlled trial was conducted to test the preliminary effects of "MyHealthPortal" using a small sample (n = 74) with three observations (baseline and 4 and 12 weeks). The intervention group showed significantly greater improvement than the control group in patient-provider communication at 4 weeks (t56 = 3.00, P = .004). For other variables, the intervention group tended to show greater improvement; however, the differences were not significant. In this preliminary study, Patient-Centered Personal Health Record and Patient Portal Implementation Toolkit showed potential for filling the gap in the current

  16. A Cell-Centered Multiphase ALE Scheme With Structural Coupling

    Energy Technology Data Exchange (ETDEWEB)

    Dunn, Timothy Alan [Univ. of California, Davis, CA (United States)


    A novel computational scheme has been developed for simulating compressible multiphase flows interacting with solid structures. The multiphase fluid is computed using a Godunov-type finite-volume method. This has been extended to allow computations on moving meshes using a direct arbitrary-Eulerian- Lagrangian (ALE) scheme. The method has been implemented within a Lagrangian hydrocode, which allows modeling the interaction with Lagrangian structural regions. Although the above scheme is general enough for use on many applications, the ultimate goal of the research is the simulation of heterogeneous energetic material, such as explosives or propellants. The method is powerful enough for application to all stages of the problem, including the initial burning of the material, the propagation of blast waves, and interaction with surrounding structures. The method has been tested on a number of canonical multiphase tests as well as fluid-structure interaction problems.

    Full Text Available Background/Aim: Solitary rectal ulcer syndrome (SRUS is a benign, chronic defecation disorder with varied presentations. The aim of this study is to summarize the clinical features, endoscopic findings, histological appearance, and treatment strategies associated with SRUS. Patients and Methods: This is a retrospective study of all patients diagnosed with SRUS at the King Faisal Specialist Hospital and Research Centre in Riyadh from January 2003 to December 2013. Cases were identified using the Department of Pathology database. Data were obtained from medical records that included clinical manifestation, endoscopic findings, and histopathological features. Results: Twenty patients were identified. The mean age was 42.5 years (±18.5 and 55% were females. Most of the patients presented with bleeding per rectum (85%, constipation (75%, and straining (50%, with a mean symptom duration of 26.7 months. The most common associated factors identified were constipation (75%, history of rectal surgery (25%, digital rectal manipulation (20%, and rectal prolapse (20%. Endoscopic findings included a single ulcer (50% and multiple ulcers (30%; 55% had a polypoidal appearance. On histopathology, there was surface ulceration (95%, fibrosis of the lamina propria (60%, distorted architecture (55%, and muscle hypertrophy with increased mucin production (50%. Patients were treated conservatively and none required surgery. Conclusion: SRUS is a rare disorder with variable clinical presentations. Stool softeners, a high fiber diet in addition to topical mesalamine, and biofeedback proved to be effective in this patient population.

  18. Evaluating trauma center structural performance: The experience of a Canadian provincial trauma system

    Directory of Open Access Journals (Sweden)

    Lynne Moore


    Full Text Available Background: Indicators of structure, process, and outcome are required to evaluate the performance of trauma centers to improve the quality and efficiency of care. While periodic external accreditation visits are part of most trauma systems, a quantitative indicator of structural performance has yet to be proposed. The objective of this study was to develop and validate a trauma center structural performance indicator using accreditation report data. Materials and Methods: Analyses were based on accreditation reports completed during on-site visits in the Quebec trauma system (1994-2005. Qualitative report data was retrospectively transposed onto an evaluation grid and the weighted average of grid items was used to quantify performance. The indicator of structural performance was evaluated in terms of test-retest reliability (kappa statistic, discrimination between centers (coefficient of variation, content validity (correlation with accreditation decision, designation level, and patient volume and forecasting (correlation between visits performed in 1994-1999 and 1998-2005. Results: Kappa statistics were >0.8 for 66 of the 73 (90% grid items. Mean structural performance score over 59 trauma centers was 47.4 (95% CI: 43.6-51.1. Two centers were flagged as outliers and the coefficient of variation was 31.2% (95% CI: 25.5% to 37.6%, showing good discrimination. Correlation coefficients of associations with accreditation decision, designation level, and volume were all statistically significant (r = 0.61, -0.40, and 0.24, respectively. No correlation was observed over time (r = 0.03. Conclusion: This study demonstrates the feasibility of quantifying trauma center structural performance using accreditation reports. The proposed performance indicator shows good test-retest reliability, between-center discrimination, and construct validity. The observed variability in structural performance across centers and over-time underlines the importance of

  19. Karyotype Learning Center: A Software For Teaching And Learning Cytogenetics

    Directory of Open Access Journals (Sweden)

    Joelma Freire De Mesquita


    Full Text Available The in vitro cultivation of human cells is an essential part of the work of every diagnostic cytoge-netics laboratory. Almost all human cytogenetic studies involve the examination of dividing bloodcell population by blocking cell division at metaphase with subsequent processing and staining bybanding techniques. The chromosome constitution is described as Karyotype that states the totalnumber of chromosomes and the sex chromosome constitution. Karyotypes are prepared by cuttingup a photograph of the spread metaphase chromosomes, matching up homologous chromosomes andsticking them back down on a card or nowadays more often by getting an image analysis computerto do the job. Chromosomes are identied by their size, centromere position and banding pattern.Teaching a student how to detect and interpret even the most common chromosome abnormaliti-es is a major challenge: mainly, in a developing country where the laboratorial facilities are notalways available for a big number of students. Therefore, in this work we present an educationalsoftware for teaching undergraduate students of Medical and Life Sciences Courses how to arrangenormal and abnormal chromosomes in the form of karyotype. The user, using drag-and-drop, is da-red to match up homologous chromosome. For that, we have developed a free full access web site( for hosting the software. The latter has proved to be light andfast even under slow dial-up connections. This web site also oers a theoretical introductory sectionwith basic concepts about karyotype. Up to now the software has been successfully applied to un-dergraduate courses at the University of Rio de Janeiro (UNIRIO. The students have approved thesoftware; to them the similarities with the well-known game solitaire turns the exercise more excitingand provides additional stimulus to learn and understand karyotype. Professors have also used thesoftware as complementary material in their regular classes

  20. Brainstorming and beyond a user-centered design method

    CERN Document Server

    Wilson, Chauncey


    Brainstorming and Beyond describes the techniques for generating ideas verbally, in writing, or through sketches. The first chapter focuses on brainstorming, the foundation method for ideation, which is a complex social process building off of social psychology principles, motivational constructs, and corporate culture. Brainstorming is commonly portrayed as an easy way to generate ideas, but in reality, it is a complex social process that is often flawed in ways that are not self-evident. Chapter 2 discusses Brainwriting, which is a variation on brainstorming in which each person writes idea

  1. Towards a realistic astrophysical interpretation of the Galactic center excess

    CERN Document Server

    Gaggero, Daniele; Urbano, Alfredo; Valli, Mauro; Ullio, Piero


    A spherical-symmetric gamma-ray emission from the central region of the Galaxy has been recently identified in Fermi-LAT data, and initially associated to dark matter particle annihilations. Guided by the evidence for a high gas density in the inner kpc of the Galaxy correlated with a very large Supernova rate, and hence with ongoing cosmic-ray acceleration, we investigate instead the possibility of addressing this excess in terms of ordinary cosmic-ray sources and standard steady-state diffusion. We introduce the new ingredient in the context of the template-fitting algorithm, treating the new contribution as correlated to the conventional Inverse Compton emission. We analyze in detail the overall goodness of the fit of our framework, and perform a detailed direct comparison against data examining profiles in different directions.

    Coluccio, M; Havlick, K


    Mergers of new health care entities require visionary leadership in forming effective partnerships. Shared leadership was one key ingredient in blending two major health care competitors in the Northwest. Building a successful foundation for shared leadership required formation of a common vision, definition of core values, and establishment of guiding principles. Honoring respective cultures, recognizing achievements, and inviting participation led to the design of the shared leadership model focused on the primary objective for the merger: Enhancing health care services to the community.

  4. [Organizational climate, trust and burnout in a rehabilitation center]. (United States)

    Bettinardi, O; Montagner, V; Maini, M; Vidotto, G


    Today human resources are considered of fundamental importance and necessity for the success of the organizations that provide health services. The aims of the present study were: 1) to investigate the perception that rehabilitation medical staff employees have of their hospital organization, 2) to quantify their evaluation concerning organizational trust, 3) to identify eventual burnout symptoms and their relationship with perceived organizational climate and trust. The sample consisted of 131 employees, subdivided into 6 professional categories. Three questionnaires were administered to the employees. The results evidenced significant differences between the various professional groups regarding the climate perceived and trust in the organization. Administrative personnel, nurses and medical graduates revealed a greater satisfaction, responsibility and work integration than the other employee groups (p = 0.023). All the scales which measured organizational climate correlated (inversely) with those measuring burnout (p" 0.05), indicating the existence of a close relationship between a work climate perceived as collaborative (r = -0.33) and characterized by a continuous exchange of information about the hospital organization (r = -0.50), and the psychological well-being experienced by the employees. This study confirms the importance of promoting organizational strategies aimed at mutual reinforcement and support characterized by regular and constructive feedback, wherein there is a reciprocal recognition of each employee's role through a clear, open communication.

  5. Complicated eclampsia: fifteen years' experience in a referral medical center. (United States)

    Lopez-Llera, M


    The statistical study of a large number of eclamptic patients (n = 704), divided into five successive 3-year periods, was undertaken at the Hospital de Gineco-Obstetricia No. 2 del Centro Médico Nacional in Mexico City in orders to detect significant changes in therapeutic results and/or in the basic character of the disease, as it occurs in a large referral medical complex. The following variables were studied: maternal and perinatal deaths, obstetric profile, main clinical data of the eclamptic episode, frequency of cesarean operation, timing of delivery after admission, main therapeutic changes, frequency of complications in survivors of ante- and intrapartum eclampsia, and cause of death with associated complications. The study showed (1) a continuous increment in the number of cases from the first to the last period, (2) averages for maternal age (24.9 +/- 0.45 years) and for previous parity (1.7 +/- 0.19) unlike those commonly accepted, (3) a significant progression in the severity of the disease in recent years, (4) a frequency of 22.9% of important complications in survivors of ante- and intrapartum eclampsia, and (5) a very limited overall influence of some therapeutic changes on the final outcome of complicated eclampsia, and (6) the impossibility of improving morbidity figures significantly during the 15 years of the study. It was concluded that prevention, early diagnosis, and timely simple medical care offer the only perspective for true medical progress in this particular problem.

  6. What is Patient-Centered Care? A Typology of Models and Missions. (United States)

    Tanenbaum, Sandra J


    Recently adopted health care practices and policies describe themselves as "patient-centered care." The meaning of the term, however, remains contested and obscure. This paper offers a typology of "patient-centered care" models that aims to contribute to greater clarity about, continuing discussion of, and further advances in patient-centered care. The paper imposes an original analytic framework on extensive material covering mostly US health care and health policy topics over several decades. It finds that four models of patient-centered care emphasize: patients versus their parts; patients versus providers; patients/providers/states versus "the system"; and patients and providers as persons. Each type is distinguishable along three dimensions: epistemological orientations, practical accommodations, and policy tools. Based on this analysis, the paper recommends that four questions be asked of any proposal that claims to provide patient-centered care: Is this care a means to an end or an end in itself? Are patients here subjects or objects? Are patients here individuals or aggregates? How do we know what patients want and need? The typology reveals that models are neither entirely compatible nor entirely incompatible and may be usefully combined in certain practices and policies. In other instances, internal contradictions may jeopardize the realization of coherent patient-centered care.

  7. Centering the Peripheral: A Case for Poetry in Africa

    Directory of Open Access Journals (Sweden)

    Joseph Muleka


    Full Text Available This paper grapples with a frequently asked question: Is there a case for poetry in Africa? Though not necessarily a polemical rooting for recognition of African oral poetry, the paper stands in contention with assertions that have tended to dismiss the said artworks as non-poetry, while at the same time attempting to confer superiority of the written poetry over the oral. In particular, the paper contests the arguments by some pioneer researchers into African literature that posited that what was usually touted as poetry in Africa did not qualify as true poetry, but rather, simply songs and chants. In an attempt to address the nitty-gritty of this subject the paper tackles the crucial question of what constitutes poetry and whether there is a significant difference between a song and a poem. The paper employs the theory of ethno-poetics which takes interest in the aesthetic components and poetic structuring of oral poems. Ethnopoetics gives guidelines on how to organize an oral text in lines to render its fullest charge of texture: rhythm, nuance, phrasing and other components that allow full poetic meaning. It is intended that the poetic restructuring will particularly help realize the poetic qualities in African poetic works. Besides, the paper also tries to popularize “narrato-centric” approach, an application we used earlier during a discussion on theory in the study of oral literature. The approach encourages the study of oral literature material that puts emphasis on performance and the dynamics dictating the performer and his role in the performance.

  10. Evaluation of the organizational cultural competence of a community health center: a multimethod approach. (United States)

    Cherner, Rebecca; Olavarria, Marcela; Young, Marta; Aubry, Tim; Marchant, Christina


    Cultural competence is an important component of client-centered care in health promotion and community health services, especially considering the changing demographics of North America. Although a number of tools for evaluating cultural competence have been developed, few studies have reported on the results of organizational cultural competence evaluations in health care or social services settings. This article aims to fill this gap by providing a description of a cultural competence evaluation of a community health center serving a diverse population. Data collection included reviewing documents, and surveying staff, management, and the Board of Directors. The organization fully met 28 of 53 standards of cultural competence, partially met 21 standards, and did not meet 2 standards, and 2 standards could not be assessed due to missing information. The advantages and lessons learned from this organizational cultural competence evaluation are discussed.

  11. Proposed Experiment to Study Relaxation Formation of a Spherical Tokamak with a Plasma Center Column (United States)

    Hsu, S. C.; Tang, X. Z.


    A spherical tokamak (ST) with a plasma center column (PCC) can be formed via driven magnetic relaxation of a screw pinch plasma. An ST-PCC could in principle eliminate many problems associated with a material center column, a key weakness of the ST reactor concept. This work summarizes the design space for an ST-PCC in terms of flux amplification, aspect ratio, and elongation, based on the zero-β Taylor-relaxed analysis of Tang & Boozer [Phys. Plasmas 13, 042514 (2006)]. The paper will discuss (1) equilibrium and stability properties of the ST-PCC, (2) issues for an engineering design, and (3) key differences between the proposed ST-PCC and the ongoing Proto-Sphera effort in Italy.

  12. A construct-driven investigation of gender differences in a leadership-role assessment center. (United States)

    Anderson, Neil; Lievens, Filip; van Dam, Karen; Born, Marise


    This study examined gender differences in a large-scale assessment center for officer entry in the British Army. Subgroup differences were investigated for a sample of 1,857 candidates: 1,594 men and 263 women. A construct-driven approach was chosen (a) by examining gender differences at the construct level, (b) by formulating a priori hypotheses about which constructs would be susceptible to gender effects, and (c) by using both effect size statistics and latent mean analyses to investigate gender differences in assessment center ratings. Results showed that female candidates were rated notably higher on constructs reflecting an interpersonally oriented leadership style (i.e., oral communication and interaction) and on drive and determination. These results are discussed in light of role congruity theory and of the advantages of using latent mean analyses.

  13. Shoulder dystocia: simulation and a team-centered protocol. (United States)

    Grobman, William A


    Shoulder dystocia is an obstetric emergency that has been reported to occur in 0.2-3% of all vaginal deliveries. Several characteristics of shoulder dystocia make it a particular challenge to manage effectively. It is relatively infrequent, the diagnosis cannot be made according to a single objective criterion that can be recognized to exist by all members of the care team who are present, it is unpredictable, and there is the need for coordinated actions of all members of the health care team who have come together on the day of the delivery and may not have worked together before or specifically during a shoulder dystocia. In general, there is evidence from different medical disciplines that checklists/protocols and simulation may be used to enhance team performance. There is also some evidence, albeit limited, that such techniques may be used to improve shoulder dystocia outcomes.

    Introducción: la queratoplastía penetrante (QP) es considerada como el trasplante orgánico más frecuentemente realizado y con mayor éxito. Las indicaciones de trasplante de córnea han cambiado con el tiempo y varían en función del país. Se han identificado factores de riesgo de rechazo corneal, como edad, vascularización corneal, cirugías oculares, etcétera. El objetivo fue identificar la categoría pronóstica, el grupo de riesgo y los factores asociados de pacientes con trasplante de córnea del Centro Médico Nacional La Raza. Métodos: se hizo un estudio transversal, analítico, observacional y ambispectivo, con fines ópticos y terapéuticos, de pacientes de la base de datos de trasplante corneal registrados entre 2011 y 2013 en el centro médico mencionado. Resultados: se obtuvieron 539 registros. El diagnóstico más frecuente fue el queratocono (29.1 %), en segundo lugar el leucoma (27.8 %) y la queratopatía bulosa pseudofáquica (25.6 %) en tercero. El 57.5 % de los pacientes correspondieron a la categoría pronóstica 2, con pronóstico de transparencia corneal muy bueno. Conclusiones: el diagnóstico más frecuente en la base de datos de trasplante de córnea fue el queratocono. Es necesaria una actualización de la clasificación pronóstica con base en todos los factores asociados conocidos, a fin de ser más acertados en el pronóstico del TC.

  19. Integrating Software Repository Mining: A Decision Support Centered Approach

    Directory of Open Access Journals (Sweden)

    Luiz Dourado Dias Junior


    Full Text Available Mining software repositories (MSR research had significantly contributed to software engineering.However, MSR results integration across repositories is a recent concern that is getting more attentionfrom researchers each day. Some noticeable research in this sense is related to the approximation betweenMSR and semantic web, specially linked data approaches which makes it possible to integrate repositoriesand mined results. Manifested that way, we believe that current research is not fully addressing thepractical integration of MSR results, specially, in software engineering due to not considering that theseresults needs to be integrated to the tools as assistance to activity performers, as a kind of decision makingsupport. Based on this statement this research describes an approach, named Sambasore, which isconcerned with MSR results inter-repository integration and also to decision making support processes,based on tool assistance modelling. To show its feasibility we describe the main concepts, some relatedworks and also a proof of concept experiment applied to a software process modelling tool named SpiderPM.

  20. Autotransplantation of pancreatic islets. A single-center first experience. (United States)

    Magistri, Paolo; Andreani, Sara; Lo Conte, Domenico; Ferrari, Giovanni Carlo; Forgione, Antonello; Pugliese, Raffaele


    L’autotrapianto d’isole pancreatiche (IAT) è una procedura ben nota che consente di migliorare il controllo glicemico dopo una pancreasectomia totale (o completamento di pancreasectomia dopo duodenocefalopancreasectomia) rispetto alla sola terapia insulinica. In questo lavoro presentiamo la nostra esperienza nel campo dell’ IAT riportando il caso clinico di una donna di sessanta anni, sottoposta a completamento di pancreasectomia per episodi ricorrenti di acuzie in un quadro di pancreatite cronica. Il trattamento IAT è stato somministrato mediante iniezione trans-epatica intra-portale. Il recupero post-procedurale è stato ottimale, fatta eccezione per un’infezione di ferita che ha richiesto un trattamento con tecnologia a pressione negativa. La paziente è stata dimessa in ventisettesima giornata postoperatoria, in buone condizioni generali, dopo regolare ripresa dell’alimentazione e della canalizzazione. I dati presenti in letteratura dimostrano che la IAT è una procedura sicura, garantendo nel lungo periodo un vantaggio rispetto alla terapia insulinica in termini di rapporto costo-beneficio. Riguardo alla procedura chirurgica, è qui utile ricordare che la mortalità a 30 giorni dopo pancreasectomia totale associata a IAT è del 5%, ed è pertanto sovrapponibile ai risultati della pancreasectomia totale senza IAT. Riportando questa esperienza intendiamo contribuire alla crescita della casistica chirurgica attuale in questo campo, proponendo nel futuro un più ampio sviluppo e una più estesa applicazione di tale approccio.

  1. Five years' experience with capsule endoscopy in a single Center

    Institute of Scientific and Technical Information of China (English)

    Taylan Kav; Yusuf Bayraktar


    Capsule endoscopy (CE) is a novel technology that facilitates highly effective and noninvasive imaging of the small bowel. Although its efficacy in the evaluation of obscure gastrointestinal bleeding (OGIB) has been proven in several trials, data on uses of CE in different small bowel diseases are rapidly accumulating in the literature, and it has been found to be superior to alternative diagnostic tools in a range of such diseases.Based on literature evidence, CE is recommended as a first-line investigation for OGIB after negative bidirectional endoscopy. CE has gained an important role in the diagnosis and follow-up of Crohn's disease and celiac disease and in the surveillance of small bowel tumors and polyps in selected patients. Capsule retention is the major complication, with a frequency of 1%-2%. The purpose of this review was to discuss the procedure, indications, contraindications and adverse effects associated with CE. We also review and share our five-year experience with CE in various small bowel diseases. The recently developed balloon-assisted enteroscopies have both diagnostic and therapeutic capability. At the present time, CE and balloon-assisted enteroscopies are complementary techniques in the diagnosis and management of small bowel diseases.

    Giardino, Antonello; Miller, Frank H.; Kalb, Bobby; Ramalho, Miguel; Martin, Diego R.; Rodacki, Karina; Woosley, John T.; Semelka, Richard C.


    Objective To determine common imaging findings of hepatic epithelioid hemangioendothelioma on magnetic resonance images. Materials and Methods A search was made of three institutional databases between January 2000 and August 2012. Seven patients (mean age, 47 years; range, 21-66 years; 6 women) with pathology-confirmed diagnosis of hepatic epithelioid hemangioendothelioma who had undergone magnetic resonance imaging were identified. None of the patients had received any treatment for hepatic epithelioid hemangioendothelioma at the time of the initial magnetic resonance imaging examination. Results Hepatic epithelioid hemangioendothelioma tumors appeared as focal masses in 7/7 patients, greater than 5 in number, with a coalescing lesion in 1/5, and peripheral localization in 6/7. Capsular retraction was present in 4/7, and was associated with peripherally located lesions. Early ring enhancement was appreciated in the majority of lesions in 7/7 patients. Centripetal progressive enhancement was shown in 5/7 patients on venous phase that exhibited a distinctive thick inner border of low signal on venous phase images, and a central core of delayed enhancement. Small lesions did not show this. Conclusion The combination of multifocal round-configuration lesions that are predominantly peripheral and exhibit early peripheral ring enhancement and late appearance of an inner thick border of low signal and central core of high signal may represent an important feature for hepatic epithelioid hemangioendothelioma.

    Full Text Available Introduction. Colonic obstruction is one of the manifestations of colon cancer for which self-expanding metal stents (SEMS have been effectively used, to restore the luminal patency either for palliative care or as a bridge to resective surgery. The aim of our study is to evaluate the efficacy and safety of large diameter SEMS in patients with malignant colorectal obstruction. Methods and Results. A four-year retrospective review of the Medical Archival System was performed and identified 16 patients. The average age was 70.8 years, of which 56% were females. The most common cause of obstruction was colon cancer (9/16, 56%. Rectosigmoid was the main site of obstruction (9/16 and complete obstruction occurred in 31% of cases. The overall technical and clinical success rates were 100% and 87%, respectively. There were no immediate complications (<24 hours, but stent stenosis due to kinking occurred within one week of stent placement in 2 patients. Stent migration occurred in 2 patients at 34 and 91 days, respectively. There were no perforations or bleeding complications. Conclusion. Large diameter SEMS provide a safe method for palliation or as a bridge to therapy in patients with malignant colonic obstruction with high technical success and very low complication rates.

  10. Shift of the Acoustic Center of a Closed-Box Loudspeaker in a Linear Array: Investigation Using the Beamforming Technique

    DEFF Research Database (Denmark)

    Chang, Ji-Ho; Jensen, Joe; Agerkvist, Finn T.


    The center of the spherical waves radiated from a loudspeaker is defined as its acoustic center. This study aims to investigate how the acoustic center of a closed-box loudspeaker is shifted when the loudspeaker is placed in a linear array. That is, the acoustic center of the loudspeaker...... is estimated when the loudspeaker is placed alone and then the loudspeaker is placed in a linear array composed of two or three identical loudspeakers. The acoustic center of each loudspeaker in the linear arrays is estimated with the other loudspeakers turned off and compared with that in the single...... loudspeaker case. In order to estimate the acoustic center based on the wave fronts, a method is proposed that measures sound pressure around the loudspeaker with an array of microphones and uses the beamforming method for the reduction of the effect of the experimental errors.

    BACKGROUND: Percutaneous transcatheter closure (PTC) of patent foramen ovale (PFO) is implicated in cryptogenic stroke, transitional ischemic attack (TIA) and treatment of a migraine. AIM: Our goal was to present our experience in the interventional treatment of PFO, as well as to evaluate the short and mid-term results in patients with closed PFO. MATERIAL AND METHODS: Transcatheter closure of PFO was performed in 52 patients (67.3% women, mean age 40.7 ± 11.7 years). Patients were interviewed for subjective grading of the intensity of headaches before and after the PFO closure. RESULTS: During 2 years of follow-up, there was no incidence of new stroke, TIA and/or syncope. Follow-up TCD performed in 35 patients showed complete PFO closure in 20 patients (57.1%). Out of 35 patients, 22 (62.9%) reported having a migraine before the procedure with an intensity of headaches at 8.1 ± 1.9 on a scale from 1 to 10. During 2 years of follow-up, symptoms of a migraine disappeared in 4 (18.2%) and the remaining 18 patients reported the significant decrease in intensity 4.8 ± 2.04 (p = 0.0001). In addition, following PFO closure the incidence of the headaches decreased significantly (p = 0.0001). CONCLUSIONS: Percutaneous transcatheter closure of PFO is a safe and effective procedure showing mid-term relief of neurological symptoms in patients as well as significant reduction of migraine symptoms.

    Starling Hunter


    Full Text Available Network Text Analysis (NTA is a term used to describe a variety of software - supported methods for modeling texts as networks of concepts. In this study we apply NTA to the screenplay of American Sniper, an Academy Award nominee for Best Adapted Screenplay in 2014. Specifically, we est ablish prior expectations as to the key themes associated with war films. We then empirically test whether words associated with the most influentially - positioned nodes in the network signify themes common to the war - film genre. As predicted, we find tha t words and concepts associated with the least constrained nodes in the text network were significantly more likely to be associated with the war genre and significantly less likely to be associated with genres to which the film did not belong.

  15. Virtual reality: A human centered tool for improving Manufacturing

    CERN Document Server

    Bennis, Fouad; Dépincé, Philippe


    Manufacturing is using Virtual Reality tools to enhance the product life cycle. Their definitions are still in flux and it is necessary to define their connections. Thus, firstly, we will introduce more closely some definitions where we will find that, if the Virtual manufacturing concepts originate from machining operations and evolve in this manufacturing area, there exist a lot of applications in different fields such as casting, forging, sheet metalworking and robotics (mechanisms). From the recent projects in Europe or in USA, we notice that the human perception or the simulation of mannequin is more and more needed in both fields. In this context, we have isolated some applications as ergonomic studies, assembly and maintenance simulation, design or training where the virtual reality tools can be applied. Thus, we find out a family of applications where the virtual reality tools give the engineers the main role in the optimization process. We will illustrate our paper by several examples where virtual r...

    Though frequently observed in children, intussusception is a rare state in adults. The treatment of intussusception in adults is different. In this trial, we have presented intussusception cases in adults that were treated and followed up in our department. The records of 31 adult intussusception cases surgically treated in our department between January 1993 and July 2012 were evaluated retrospectively. Among the 31 adult cases of intussusception that were treated during a period of 19 years, 10 were men, and 21 were women. The mean age was determined as 39.7 ± 5.3. The presentation symptom was abdominal pain in all the patients. Failure to pass gas or feces was observed in 23 patients (74.2 %); nausea and vomiting, in 22 patients (70.9 %); hematochezia, in 16 patients (51.6 %); and weight loss, in 3 patients (9.6 %). The mean duration of symptoms was 4.8 days. Abdominal tenderness was found in all the patients. Muscular defense and rebound tenderness were determined in 13 patients (41.9 %). Findings of intussusception were found in 80.9 % of patients examined by abdominal ultrasonography and in 63.1 % of cases examined by computerized tomography. Resection of the intussuscepted bowel segment was performed in 87 % of the patients. In conclusion, intussusception in adults is a rare clinical entity. Intussusception should be considered in the differential diagnosis in patients presenting with spasmodic abdominal pain, especially in cases with intestinal obstruction. The recommended surgical method is en bloc resection of the intussuscepted segment in cases suspected to carry a risk of malignancy.

  20. A lysosome-centered view of nutrient homeostasis. (United States)

    Mony, Vinod K; Benjamin, Shawna; O'Rourke, Eyleen J


    Lysosomes are highly acidic cellular organelles traditionally viewed as sacs of enzymes involved in digesting extracellular or intracellular macromolecules for the regeneration of basic building blocks, cellular housekeeping, or pathogen degradation. Bound by a single lipid bilayer, lysosomes receive their substrates by fusing with endosomes or autophagosomes, or through specialized translocation mechanisms such as chaperone-mediated autophagy or microautophagy. Lysosomes degrade their substrates using up to 60 different soluble hydrolases and release their products either to the cytosol through poorly defined exporting and efflux mechanisms or to the extracellular space by fusing with the plasma membrane. However, it is becoming evident that the role of the lysosome in nutrient homeostasis goes beyond the disposal of waste or the recycling of building blocks. The lysosome is emerging as a signaling hub that can integrate and relay external and internal nutritional information to promote cellular and organismal homeostasis, as well as a major contributor to the processing of energy-dense molecules like glycogen and triglycerides. Here we describe the current knowledge of the nutrient signaling pathways governing lysosomal function, the role of the lysosome in nutrient mobilization, and how lysosomes signal other organelles, distant tissues, and even themselves to ensure energy homeostasis in spite of fluctuations in energy intake. At the same time, we highlight the value of genomics approaches to the past and future discoveries of how the lysosome simultaneously executes and controls cellular homeostasis.

  1. Mycophenolate mofetil in pediatric renal transplantation: a single center experience.

    LENUS (Irish Health Repository)

    Raheem, Omer A


    We assessed our long-term experience with regards to the safety and efficacy of MMF in our pediatric renal transplant population and compared it retrospectively to our previous non-MMF immunosuppressive regimen. Forty-seven pediatric renal transplants received MMF as part of their immunosuppressive protocol in the period from January 1997 till October 2006 (MMF group). A previously reported non-MMF group of 59 pediatric renal transplants was included for comparative analysis (non-MMF group). The MMF group comprised 29 boys and 18 girls, whereas the non-MMF group comprised 34 boys and 25 girls. Mean age was 11.7 and 12 yr in the MMF and non-MMF groups, respectively. The incidence of acute rejection episodes was 11 (23.4%) and 14 (24%) in the MMF and non-MMF group, respectively. Two (3.3%) grafts were lost in the non-MMF group compared with one (2.1%) in the MMF group. Twenty-one (44.68%) patients in the MMF group developed post-transplant infections compared with 12 (20.33%) in the non-MMF group (p < 0.0001). In conclusion, the use of MMF in pediatric renal transplantation was not associated with a lower rejection rate or immunological graft loss. It did, however, result in a significantly higher rate of viral infections.

  2. Imatinib resistance mutation analysis: experience from a tertiary oncology center

    Directory of Open Access Journals (Sweden)

    Mallekavu Suresh Babu


    Full Text Available Purpose: BCR-ABL kinase domain (KD mutations account for 50-90% of the imatinib resistance observed in patients of CML-chronic phase. In CML-CP patients receiving imatinib first-line, mutation analysis is recommended in case of failure or suboptimal response using European LeukemiaNet (ELN criteria. The present study was carried out at a tertiary oncology centre in south India to assess which mutations accounted for resistance to imatinib among patients of chronic phase CML being treated with imatinib.Methods: This was a retrospective observational study. We analyzed patients who were tested for imatinib resistance mutation in view of suboptimal responses while on imatinib or imatinib failure. Direct sequencing of the BCR-ABL transcript by the Sanger method was used for IRMA testing.Results: Out of 120 tested for IRMA, 36 (30% had detectable mutations. We observed a higher frequency of mutations at amino acids T315, F359 and M351T.Conclusions: Among the patients who were tested for imatinib resistance mutation in view of suboptimal responses while on imatinib or imatinib failure, 30% had IRMA +ve mutations. The high incidence of imatinib resistance in present study may be attributed to the fact that our patients were given higher dose of imatinib (600 mg, if they failed to achieve CCyR at 12 months or CHR at 3 months as they could not afford second generation TKIs.

  3. Factors associated with a patient-centered medical home among children with behavioral health conditions. (United States)

    Knapp, Caprice; Woodworth, Lindsey; Fernandez-Baca, Daniel; Baron-Lee, Jacqueline; Thompson, Lindsay; Hinojosa, Melanie


    At some point in their lives, nearly one-half of all American children will have a behavioral health condition. Many will not receive the care they need from a fragmented health delivery system. The patient-centered medical home is a promising model to improve their care; however, little evidence exists. Our study aim was to examine the association between several behavioral health indicators and having a patient-centered medical home. 91,642 children's parents or guardians completed the 2007 National Survey of Children's Health. An indicator for patient-centered medical home was included in the dataset. Descriptive statistics, bivariate tests, and multivariate regression models were used in the analyses. Children in the sample were mostly Male (52 %), White (78 %), non-Hispanic (87 %), and did not have a special health care need (80 %). 6.2 % of the sample had at least one behavioral health condition. Conditions ranged from ADHD (6 %) to Autism Spectrum Disorder (ASD) (1 %). Frequency of having a patient-centered medical home also varied for children with a behavioral health condition (49 % of children with ADHD and 33 % of children with ASD). Frequency of having a patient-centered medical home decreased with multiple behavioral health conditions. Higher severity of depression, anxiety, and conduct disorder were associated with a decreased likelihood of a patient-centered medical home. Results from our study can be used to target patient-centered medical home interventions toward children with one or more behavioral health conditions and consider that children with depression, anxiety, and conduct disorder are more vulnerable to these disparities.

  4. Neurological events after liver transplantation: a single-center experience. (United States)

    Piñero, Federico; Mendizabal, Manuel; Quiros, Rodolfo; Fauda, Martín; Arufe, Diego; Gonzalez Campaña, Ariel; Barreiro, Mariano; Marquevich, Victoria; Raffa, María P; Cosenza, Sebastian; Andriani, Oscar; Podesta, Luis G; Silva, Marcelo


    The aim of this study was to identify potential risk factors linked to neurologic events (NE) occurring after liver transplantation (LT) and use them to construct a model to predict such events. From odds ratios (OR) of risk factors, a scoring system was assessed using multivariate regression analysis. Forty-one of 307 LT patients presented NE (13.3%), with prolonged hospital stay and decreased post-LT survival. On multivariate analysis, factors associated with NE included: severe pre-LT ascites OR 3.9 (1.80-8.41; P = 0.001), delta sodium ≥12 mEq/l OR 3.5 (1.36-8.67; P = 0.01), and post-LT hypomagnesemia OR 2.9 (1.37-5.98; P = 0.005). Points were assigned depending on ORs as follows: ascites 4 points, and hypomagnesemia and delta sodium ≥12 mEq/l, 3 points each (score range = 0-10 points). ROC curve analysis suggested good discriminative power for the model, with a c-statistic of 0.72 (CI 0.62-0.81; P 3 points (71% sensitivity, 60% specificity). NE risk increased progressively from 6.4%, to 10.3%, 12.8%, 31.5% and 71.0% as scores rose from 0 to 3, 4, 6-7 and 10 cumulative points, respectively. The score described helps to identify patients potentially at risk for neurologic events, and its prevention would decrease morbidity and mortality after LT.

  5. Hemodialysis for methyl alcohol poisoning: A single-center experience

    Vivek B Kute


    Full Text Available Methanol is a cheap and potent adulterant of illicit liquors. Hemodialysis (HD is the best method to rapidly remove both toxic acid metabolites and parent alcohols, and it plays a fundamental role in treating severely poisoned patients. This retrospective study was carried out on 91 patients with detectable serum methanol levels who underwent HD. Because toxic alcohol levels were not immediately available, the initial diagnosis and treatment was based on clinical history with evidence of toxic alcohol intake, presence of high anion metabolic acidosis and/or end organ damage. Patients received bicarbonate, ethanol, according to clinical features and blood gases. Patients underwent HD in the setting of known methanol ingestion with high anion gap metabolic acidosis, or evidence of end-organ damage, regardless of methanol level. HD prescription included large surface area dialyzer (≥1.5 m2, blood flow rate of 250-350 mL/min and dialysate flow rate of 500 mL/min for 4-6 h. Between 9 and 11 July 2009, 91 males with mean age 40 ± 8.5 years underwent HD, and 13 patients required a second HD session. Patients consumed 100-500 mL illicit liquors, and symptoms appeared six and 60 h later. Clinical features were gastro-intestinal symptoms (83.5%, visual disturbances (60.4%, central nervous system symptoms (59.3% and dyspnea (43.9%. Before HD, mean pH was 7.11 ± 0.04 (range 6.70- 7.33 and mean bicarbonate levels were 8.5 ± 4.9 mmol/L (range 2-18. Three patients died due to methanol intoxication. Mortality was associated with severe metabolic acidosis (pH ≤ 6.90, ventilator requirement and coma/seizure on admission (P < 0.001. Timely HD, bicarbonate, ethanol and supportive therapy can be life-saving in methanol intoxication.

    Full Text Available Aim: We aimed to study the cost of stroke, its predictors, and the impact on social determinants of the family. Settings and Design: This prospective study was done in the Stroke unit and Neurology clinic between April 2009 and October 2011. Materials and Methods: All first ever stroke patients during the study period were enrolled. Direct and indirect costs at admission, at 1 and 6 months follow-up were obtained. The follow-up included information about the patient′s poststroke outcome using modified Rankin Scale (mRS, work status, modifications made at home, loan requirement, etc., Results: Two hundred patients were enrolled in this study and final analysis was performed on 189 patients. The mean age was 58 ± 13 years and 128 (67.7% were men. Majority (54% were living in a joint family. The mean overall cost of stroke per patient was rupees (INR 80612 at 6 months. Higher income (P = 0.008, poor outcome (mRS >2 (P = 0.001, and length of hospital stay (P = 0.001 were the cost driving factors of total cost of stroke at 6 months. There was a decline in the requirement of help (P < 0.0001 and need for loan (P = 0.003 at 6 months follow-up. Conclusions: Direct medical cost or acute care of stroke accounted for a major component of cost of stroke. Poor outcome, length of hospital stay, and higher income were the cost driving factors. The socioeconomic impact on the family decreased at follow up probably due to joint family system.

  7. A survey of program evaluation practices in family-centered pediatric rehabilitation settings. (United States)

    Moreau, Katherine A; Cousins, J Bradley


    Program evaluation is becoming increasingly important in pediatric rehabilitation settings that adhere to the family-centered service (FCS) philosophy. However, researchers know little about the specific evaluation activities occurring in these settings or the extent to which evaluators/service providers uphold FCS in their program evaluation activities. Through a questionnaire survey, this study aimed to document evaluators/service providers' perceptions of the level of program evaluation occurring in their Canadian pediatric rehabilitation centers. It also investigated the extent to which evaluators/service providers perceive program evaluation practices at their centers to be consistent with the FCS context of Canadian pediatric rehabilitation settings. The findings suggested that the amount of evaluation activities occurring within the respondents' centers is variable; that the majority of individuals working in program evaluation do not have formal training in it; and that the respondents' centers have limited resources for evaluation. The study also showed that staff members believe their centers' evaluation activities are somewhat consistent with FCS philosophy, but that improvements are needed.

  8. A Stringent Constraint on Alternatives to a Massive Black Hole at the Center of NGC 4258 (United States)

    Maoz, Eyal


    There is now dynamical evidence for massive dark objects at the center of several galaxies, but suggestions that these are supermassive black holes are based only on indirect astrophysical arguments. As emphasized by Kormendy and Richstone, large M/L ratios and gas motions of order ~103 km s-1 do not uniquely imply a massive black hole (BH), and it is possible that the central dark objects in these galaxies are massive clusters of stellar remnants, brown dwarfs, low-mass stars, or halo dark matter. The recent unprecedented measurement of the rotation curve of maser emission sources at the center of NGC 4258, and the remarkable discovery that it is Keplerian to high precision, provide us with a unique opportunity for testing alternatives to a BH. We use a conservative upper limit on the systematic deviation from a Keplerian rotation curve to constrain the mass distribution at the galaxy center. Based on evaporation and physical collision timescale arguments, we show that a central cluster is firmly ruled out, unless the cluster consists of extremely dense objects with mass BH. We also show that the mass of the BH must be >~98% of the mass enclosed within the inner edge of the masering disk (3.6 x 107 M⊙). A substantial contribution to that mass from a density cusp in the background mass distribution is excluded.

  9. Rethinking Regenerative Medicine: A Macrophage-Centered Approach

    Directory of Open Access Journals (Sweden)

    Bryan N Brown


    Full Text Available Regenerative medicine, a multi-disciplinary approach that seeks to restore form and function to damaged or diseased tissues and organs, has evolved significantly during the past decade. By adapting and integrating fundamental knowledge from cell biology, polymer science, and engineering, coupled with an increasing understanding of the mechanisms which underlie the pathogenesis of specific diseases, regenerative medicine has the potential for innovative and transformative therapies for heretofore unmet medical needs. However, the translation of novel technologies from the benchtop to animal models and clinical settings is non-trivial and requires an understanding of the mechanisms by which the host will respond to these novel therapeutic approaches. The role of the innate immune system, especially the role of macrophages, in the host response to regenerative medicine based strategies has recently received considerable attention. Macrophage phenotype and function have been suggested as critical and determinant factors in downstream functional outcomes. The constructive and regulatory, and in fact essential, role of macrophages in positive outcomes represents a significant departure from the classical paradigms of host-biomaterial interactions, which typically consider activation of the host immune system as undesirable. It appears desirable that emerging regenerative medicine approaches should not only accommodate, but promote, the involvement of the immune system to facilitate positive outcomes. Herein, we describe the current understanding of macrophage phenotype as it pertains to regenerative medicine and suggest that improvement of our understanding of context-dependent macrophage polarization will lead to concurrent improvement in outcomes.

    Deceased donor renal transplantation (DDRT) constitutes less than 5% of all kidney transplantats in India. A retrospective analysis of 173 deceased donor renal transplants performed in a public funded government hospital was done. Mean age of the recipients was 36 years (male:female ratio 2.4:1), and that of the donors was 32.3 years (male:female ratio 6:1). The cold ischemic time was 340 ± 170 minutes. Mean follow-up period was 36 months. Forty one patients died, 75% of them in the first post – transplant year. Sepsis and cardiovascular disease were the most common causes of death. Twenty two percent had acute rejection. There was no significant difference in the incidence in the rate of acute rejection, bacterial, fungal infections and death rate between the cohorts of induction and non induction immunosuppression. The patient and death censored graft survival at 1 year were 80 and 82.6% and at 5 years were 76 and 80% respectively. PMID:28182043

    Full Text Available BACKGROUND: Percutaneous pulmonary valvuloplasty is well established treatment of choice in pulmonary valve stenosis. AIM: The aim of our study was to present our experience with the interventional technique, its immediate and mid-term effectiveness as well as its complication rate. MATERIAL AND METHODS: The study included 43 patients, where 33 (74% of them were children between the age of 1 month and 15 years. RESULTS: The procedure was successful in 38 patients or 90%. Mean peak to peak transvalvular gradient was reduced from 91.2 mmHg (55-150 mmHg to 39.1 mmHg (20-80 mmHg. Follow- up of patients was between 2 and 13 years and included echocardiographic evaluation of pulmonary valve gradient, right heart dimensions and function as well as assessment of pulmonary regurgitation. We experienced one major complication pericardial effusion in a 5 months old child that required pericardiocenthesis. Six patients (13.9% required a second intervention. During the follow up period there was significant improvement of right heart function and echocardiography parameters. Mild pulmonary regurgitation was noted in 24 (55% patients, and four (9% patients developed moderate regurgitation, without affecting the function of the right ventricle. CONCLUSIONS: Percutaneous pulmonary valvuloplasty is an effective procedure in treatment of pulmonary stenosis with good short and mid-term results.

  12. [The adipose tissue as a regulatory center of the metabolism]. (United States)

    Fonseca-Alaniz, Miriam H; Takada, Julie; Alonso-Vale, Maria Isabel C; Lima, Fabio Bessa


    The recent progress in the research about the metabolic properties of the adipose tissue and the discovery of its ability to produce hormones that are very active in pathophysiologic as well as physiologic processes is rebuilding the concepts about its biology. Its involvement in conditions like obesity, type 2 diabetes mellitus, arterial hypertension, arteriosclerosis, dislipidemias and chronic and acute inflammatory processes indicate that the understanding of its functional capacities may contribute to improve the prognosis of those diseases whose prevalence increased in a preoccupying manner. Here we review some functional aspects of adipocytes, such as the metabolism, its influence on energy homeostasis, its endocrine ability and the adipogenesis, i.e., the potential of pre-adipocytes present in adipose tissue stroma to differentiate into new adipocytes and regenerate the tissue. In addition, we are including some studies on the relationship between the adipose tissue and the pineal gland, a new and poorly known, although, as will be seen, very promising aspect of adipocyte physiology together with its possible favorable repercussions to the therapy of the obesity related diseases.

    Directory of Open Access Journals (Sweden)

    Kakar S


    Full Text Available Chlamydia trachomatis is considered a major aetiological agent of conjunctivitis in newborns. The objective of the present study was to determine the aetiology of neonatal conjunctivitis and clinico-epidemiological correlates of chlamydial ophthalmia neonatorum. Fifty-eight newborns with signs and symptoms of conjunctivitis were studied. Conjunctival specimens were subjected to Gram staining, routine bacteriological culture, culture for Neisseria gonorrhoeae and direct fluorescent antibody (DFA staining for diagnosis of C. trachomatis infection. C. trachomatis was detected in 18 (31% neonates. Findings suggest that since C. trachomatis is the most common cause of neonatal conjunctivitis, routine screening and treatment of genital C. trachomatis infection in pregnant women and early diagnosis and treatment of neonatal Chlamydial conjunctivitis may be considered for its prevention and control.

    Full Text Available This study was undertaken to find out the profile of intractable epilepsy (IE in a tertiary referral centre. 100 patients (males 67; females 33 with IE attending the epilepsy clinic were evaluated. Detailed history, examination, investigations like EEG and CT scan and details regarding pharmacotherapy were analysed. The age of the patients ranged from 5 to 70 yrs (mean=23.2 yrs. Mean duration of seizures was 11.44 years. Commonest seizure type was partial seizures (74%. Amongst patients with generalised seizures (26%, 14% had multiple seizure types. The seizure frequency was 12.39 +/- 21.57 (mean +/- SD per month. Fifty seven patients were in the symptomatic group with CNS infections being the leading cause (19% of epilepsy. Fifty patients had one or more abnormal predictors of IE. There was no difference in the severity of epilepsy in patients with no abnormal feature when compared with patients having abnormal features. EEG was abnormal in 69% cases with background abnormality in 20% and focal abnormality in 36% cases. CT scan was abnormal in 41% cases with commonest abnormality being neurocysticercosis (11% followed by gliosis (9% and chronic infarct (9%. Sixty patients were receiving a combination of two drugs, 32 patients 3 drugs and 8 patients were on 4 drugs. There was no difference in seizure control in patients who were on 2 drugs or more than 2 drugs. Partial seizures were the commonest seizure type leading to IE; CNS infection being the leading aetiological factor. The presence or absence of predictors of intractability does not predict severity of epilepsy. Addition of third primary drug to existing combination only increases adverse effects without better control of seizures.

    We develop a general notion of orthogonal wavelets `centered' on an irregular knot sequence. We present two families of orthogonal wavelets that are continuous and piecewise polynomial. As an application, we construct continuous, piecewise quadratic, orthogonal wavelet bases on the quasi-crystal lattice consisting of the $\\tau$-integers where $\\tau$ is the golden-mean. The resulting spaces then generate a multiresolution analysis of $L^2(\\mathbf{R})$ with scaling factor $\\tau$.

    Background Reconstructive surgery is the primary goal in pediatric patients with valve disease.However,in cases with irreparable valve lesions,valve replacement is the only option.This study aimed to retrospectively analyze the clinical experience of heart valve prosthesis replacement in children.Methods Between January 1990 and July 2009,35 pediatric patients (16 boys,19 girls) underwent mechanical valve replacement in Shandong University Qilu Hospital.The ages ranged from 2.5 to 14 years (mean,(8.8±3.8) years) and body weight varied from 11 to 37 kg (mean,(22.1±5.2) kg).Mechanical valve replacement was performed because of congenital heart disease in 23 patients,rheumatic disease in ten patients and infective endocarditis in two patients.St.Jude bileaflet mechanical valves were implanted in all the 35 patients including mitral valve replacement (MVR) in 18,aortic valve replacement (AVR) in 12,tricuspid valve replacement (TVR) in two,AVR and MVR in two and MVR and TVR in one.The size of the prostheses ranged between 19 and 27 mm.All patients received long-term anticoagulation treatment with sodium warfarin,aiming to maintain an international normalized ratio between 1.5 to 2.0.Follow-up was performed in all the patients with a total follow-up of 119.4 patient-years.Results The operative mortality was 8.57% (3/35).One patient,who underwent cardiac debridement and AVR,died 2 hours after being admitted to the intensive care unit because of severe low cardiac output syndrome and ventricular fibrillation.Two patients died of cardiogenic shock and renal failure during initial hospitalization after the operation.One patient who received replacement of a tricuspid valve developed complete heart block requiring temporary pacing and recovered sinus rhythm 4 days later.Thirty-two patients survived and their cardiac function was in New York Heart Association (NYHA) class Ⅰ to class Ⅱ when discharged.Late events included hemorrhage and endocarditis.Two patients required

  18. Two Independent Orthogonal Stereomutations at a Single Asymmetric Center: A Narcissistic Couple. (United States)

    Gillick-Healy, Malachi W; Jennings, Elizabeth V; Müller-Bunz, Helge; Ortin, Yannick; Nikitin, Kirill; Gilheany, Declan G


    The energy barriers in our recently discovered Walden-type inversion of chlorophosphonium salts are similar to those for Cope rearrangements of caged cyclic hydrocarbons. Therefore, we have designed a molecular system that integrates the two processes, thereby producing the first embodiment of a chemical species that can undergo two entirely different and independent stereomutation mechanisms at the same nominal asymmetric center. Thus, the energy barrier to the rearrangement of 9-phenyl-9-phosphabarbaralane oxide, which is easily prepared by a new high-yielding synthesis, was found to be roughly 11 kcal mol(-1) . This value is in contrast to the parent barbaralane (7.3 kcal mol(-1) ) but in good agreement with our computational results for the rearrangement barriers. Crucially, in the corresponding chlorophosphonium derivative, two stereomutations occur simultaneously: a fast Cope rearrangement (barrier ≈12 kcal mol(-1) ) and a slow Walden-type inversion of the phosphorus center (barrier ≈21 kcal mol(-1) ). The computational model also revealed a relationship between the Cope rearrangement barrier and the bridgehead distance. The phenomenon of two independent and geometrically orthogonal stereomutations at a single asymmetric center provided important general insights into reaction pathway bifurcation, microscopic reversibility, and dynamic stereochemistry. This first example of coexisting alternative mechanisms that involve covalent bonds may encourage the design of new types of dynamic molecular structures.

    The objective of this study was to evaluate pharmacist use of a Regional Poison Information Center (RPIC), identify potential barriers to utilization, and provide strategies to overcome these barriers. All calls placed to a RPIC by a pharmacist, physician, or nurse over a 5-year period were retrieved. These data were analyzed to assess the pharmacist utilization of the RPIC and the variation of call types. Additionally, a survey, designed to assess the past and future use of the RPIC by pharmacists, was distributed to pharmacists in the region. Of the 37,799 calls made to the RPIC, 26,367 (69.8%) were from nurses, 8096 (21.4%) were from physicians, and 3336 (8.8%) were from pharmacists. Among calls initiated by pharmacists, the majority involved medication identification (n = 2391, 71.7%). The survey had a 38.9% response rate (n = 715) and revealed a trend toward less RPIC utilization by pharmacists with more formal training but less practice experience. The utilization of the RPIC was lowest among pharmacists as compared to other health care professionals. This may be due to pharmacists' unfamiliarity with the poison center's scope of services and resources. Therefore, it is important that pharmacists are educated on the benefit of utilizing poison centers in clinical situations.

    Full Text Available Introduction: Ambiguous genitalia are a major cause of parental anxiety and create psychological and social problems to patient, if not managed properly. Here we present our experience in managing patients with ambiguous genitalia. Material and Methods: We retrospectively reviewed clinical records of all patients with ambiguous genitalia managed surgically at out institute between December 1989 and January 2011. Relevant history, clinical examination , investigations and surgical procedures performed were analyzed and results were evaluated in terms of anatomical, functional and psychosexual outcomes. Results: Female pseudohermaphroditism was the most common cause of genital ambiguity in our patients. Male and female genitoplasty was done according to gender of rearing, genital anatomy and parental choice. Twenty six patients (86.6% reported satisfactory cosmetic outcome and 22 (73.3% satisfactory functional outcome on long term follow-up. Among the 24 patients diagnosed as male pseudohermaphroditism 14 (82.3% patient have reported satisfactory cosmetic outcome and 13 (76.4% have reported satisfactory functional outcome. In patients with mixed gonadal dysgenesis and true hermaphroditism satisfactory cosmetic and functional outcome was seen in 70% patient. Conclusion: Managing patients of genital ambiguity according to gender of rearing, genital anatomy and parental choice carries good prognosis in terms of anatomical, functional and psychosexual outcome.

    Calkovsky, V; Wallenfels, P; Calkovska, A; Hajtman, A


    Laryngeal cancer is about the twentieth most common cancer in the world and more than 150,000 new cases are diagnosed annually. The aim of the study was to evaluate the history, diagnostics, treatment outcomes, and prognosis in patients with laryngeal cancer in Northern Slovakia. We analyzed retrospectively 227 patients (207 males, 20 females) with laryngeal carcinoma treated in the period 2003-2014 at the Clinic of Otorhinolaryngology and Head and Neck Surgery of the Jessenius Faculty of Medicine and Martin University Hospital in Martin, Slovakia. The majority of patients were in the sixth (38.0 %) and seventh decade of life (30.8 %). Two hundred and seventeen patients (95.6 %) were smokers or ex-smokers. Sixty-six percent of patients were diagnosed with glottic or transglottic carcinoma, related probably to the anatomical structure of the larynx and exposure to inhalation pollutants. It is alarming that the majority of patients with malignant laryngeal disease were admitted to the hospital in advanced stages. In 151 (66.5 %) of patients, the extent of infiltration was T3 or T4, and 156 (68 %) patients were in disease stage III and IV. The incidence and mortality of laryngeal cancer suggest the need to intensify the prevention and to search for an early clinical stage of laryngeal cancer using a targeted screening.

Methods: Patients who applied to Dicle University Medical School Emergency Service during January 2013-December 2014 and whose serum Na>148 mEq/L were included in the study. The study was conducted retrospectively. Results: Hypernatremia prevalence was determined as 0.21% in the cases who applied to the emergency service. The average age in all patients was 69±22 and the median age was 72 years. The average hospitalization period was 13.3±10.9 days. The mortality rate was 75.7% and male gender domination (56% was determined in patients who developed mortality. When mortality and recovery groups were compared statistically; significant difference was determined (p<0.05 in terms of hospitalization period, glucose, urea, creatinine and calcium averages. The complaints of our patients who applied to the emergency service were changes in consciousness (92.7%, oral intake disorder (83.4% and fever (48.6% based on frequency order. The accompanying comorbid states were cerebrovascular illness (36.9%, Dementia/Alzheimer (32.4% and hypertension (28.9% based on frequency order. Conclusion: Consequently, hypernatremia is a fluid-electrolyte disorder progressing with high mortality and could be observed in older patients and in patients whose oral intake is defective and who have cerebrovascular illness and dementia.

  3. Can music with prosocial lyrics heal the working world? A field intervention in a call center (United States)

    Niven, Karen


    Music with lyrics about helping is shown to reduce aggression in the laboratory. This paper tests whether the prosocial lyric effect generalizes to reducing customer aggression in the workplace. A field experiment involved changing the hold music played to customers of a call center. The results of a 3 week study suggested that music significantly affected customers, but not in the way suggested by previous laboratory experiments; compared with days when instrumental background music was played, caller anger and employee exhaustion were lower on days when callers were played popular music with neutral, but not prosocial, lyrics. The findings suggest that music influences customer aggression, but that the prosocial lyric effect may not generalize from the laboratory to the call center. PMID:26052159

    Full Text Available Introduction Published data suggest that patients with acromegaly have an increased prevalence of prostate disorders. Objective To evaluate prostatic disorders in acromegalic patients comparing these results after one year of treatment of acromegaly and with a group of healthy men. Materials and Methods This study was composed of two parts: sectional study comparing patients with healthy controls (baseline and prospective, longitudinal study (at baseline and after one year of treatment. Forty acromegalic patients were enrolled and evaluated at baseline and after one year with the application of international prostatic symptoms score (IPSS, digital rectal examination, measurements of growth hormone (GH, insulin-like growth factor-I (IGF-I, insulin-like growth factor-binding protein-3 (IGFBP-3, sex hormone-binding globulin (SHBG, prolactin, luteinizing hormone (LH, follicle-stimulating hormone (FSH, total testosterone, total and free prostate-specific antigen (PSA levels and prostate ultrasonography (US. Thirty healthy men were selected as control group. Results We stratified patients and controls according to age, considering 40 years-old as cut off. Healthy controls under 40 had IPSS values lower than acromegalic patients. When considering only older patients and controls prostate hyperplasia and structural abnormalities were more frequent in acromegalics. After one year of treatment there was significant decrease in GH, IGF-I and prostate volume in acromegalics over 40 years-old. Conclusions Acromegalics under 40 have more urinary symptoms according to IPSS and above 40 years-old higher frequency of structural changes and increased prostate volume than healthy men. Significant reduction of GH and IGF-I levels during treatment of acromegaly leads to decrease in the prostate volume.

Conclusion: Previous pelvic surgeries were the major etiological factor for EP. Other factors were infertility treatment and pelvic inflammatory disease. The most common site of EP was fallopian tubes.

  6. A stringent constraint on alternatives to a massive black hole at the center of NGC 4258

    CERN Document Server

    Maoz, E


    There is now dynamical evidence for massive dark objects at the center of several galaxies, but suggestions that these are supermassive black holes are based only on indirect astrophysical arguments. The recent unprecedented measurement of the rotation curve of maser emission sources at the center of NGC 4258, and the remarkable discovery that it is Keplerian to high precision, provides us a unique opportunity for testing alternatives to a BH (e.g., a massive cluster of stellar remnants, brown dwarfs, low-mass stars, or halo dark matter). We use a conservative upper limit on the systematic deviation from a Keplerian rotation curve to constrain the mass distribution at the galaxy center. Based on evaporation and physical collision time-scale arguments, we show that a central cluster is ruled out, *unless* the cluster consists of *extremely* dense objects with mass less than about 0.05 solar masses (e.g., low mass BHs or elementary particles). Since both of these dynamically-allowed systems are very improbable ...

    Full Text Available Reza KarimiPacific University School of Pharmacy, Hillsboro, OR, USABackground: Problem-based learning (PBL has made a major shift in support of student learning for many medical school curricula around the world. Since curricular development of PBL in the early 1970s and its growth in the 1980s and 1990s, there have been growing numbers of publications providing positive and negative data in regard to the curricular effectiveness of PBL. The purpose of this study was to explore supportive data for the four core objectives of PBL and to identify an interface between the objectives of PBL and a learner-centered paradigm.Methods: The four core PBL objectives, ie, structuring of knowledge and clinical context, clinical reasoning, self-directed learning, and intrinsic motivation, were used to search MEDLINE, the Education Resources Information Center, the Educator’s Reference Complete, and PsycINFO from January 1969 to January 2011. The literature search was facilitated and narrowed if the published study included the following terms: “problem-based learning”, “medical education”, “traditional curriculum”, and one of the above four PBL objectives.Results: Through a comprehensive search analysis, one can find supportive data for the effectiveness of a PBL curriculum in achieving the four core objectives of PBL. A further analysis of these four objectives suggests that there is an interface between PBL objectives and criteria from a learner-centered paradigm. In addition, this review indicates that promotion of teamwork among students is another interface that exists between PBL and a learner-centered paradigm.Conclusion: The desire of medical schools to enhance student learning and a need to provide an environment where students construct knowledge rather than receive knowledge have encouraged many medical schools to move into a learner-centered paradigm. Implementation of a PBL curriculum can be used as a prevailing starting point to

  9. Distributed Spectrum Sensing with Sequential Ordered Transmissions to a Cognitive Fusion Center

    CERN Document Server

    Hesham, Laila; Nafie, Mohammed


    Cooperative spectrum sensing is a robust strategy that enhances the detection probability of primary licensed users. However, a large number of detectors reporting to a fusion center for a final decision causes significant delay and also presumes the availability of unreasonable communication resources at the disposal of a network searching for spectral opportunities. In this work, we employ the idea of sequential detection to obtain a quick, yet reliable, decision regarding primary activity. Local detectors take measurements, and only a few of them transmit the log likelihood ratios (LLR) to a fusion center in descending order of LLR magnitude. The fusion center runs a sequential test with a maximum imposed on the number of sensors that can report their LLR measurements. We calculate the detection thresholds using two methods. The first achieves the same probability of error as the optimal block detector. In the second, an objective function is constructed and decision thresholds are obtained via backward in...

  10. A Transient Radio Source near the Center of the Milky Way Galaxy. (United States)

    Zhao, J H; Roberts, D A; Goss, W M; Frail, D A; Lo, K Y; Subrahmanyan, R; Kesteven, M J; Ekers, R D; Allen, D A; Burton, M G; Spyromilio, J


    In late December 1990, a new radio source appeared near the center of our galaxy rivaling the intensity of Sgr A(*) (the compact radio source at the galactic center). Following its first detection, the flux density of the galactic center transient (GCT) increased rapidly to a maximum 1 month later, and then declined gradually with a time scale of about 3 months. Surprisingly, the GCT maintained a steep radio spectrum during both its rising and decay phases. The neutral hydrogen (HI) absorption shows similar absorption to that in front of Sgr A(*); this indicates that the GCT lies near the galactic center. Furthermore, both HI and OH observations show an additional deep absorption at +20 kilometers per second with respect to the local standard of rest. Thus, the GCT is either embedded in or located behind a molecular cloud moving with that velocity. The cloud can be seen on infrared images. Its opacity is shown to be inadequate to conceal a supernova near the galactic center. It is argued that the GCT was probably transient radio emission from synchrotron-radiating plasma associated with an x-ray binary system.

  11. Laser and cavity cooling of a mechanical resonator with a nitrogen-vacancy center in diamond (United States)

    Giannelli, Luigi; Betzholz, Ralf; Kreiner, Laura; Bienert, Marc; Morigi, Giovanna


    We theoretically analyze the cooling dynamics of a high-Q mode of a mechanical resonator, when the structure is also an optical cavity and is coupled with a nitrogen-vacancy (NV) center. The NV center is driven by a laser and interacts with the cavity photon field and with the strain field of the mechanical oscillator, while radiation pressure couples the mechanical resonator and cavity field. Starting from the full master equation we derive the rate equation for the mechanical resonator's motion, whose coefficients depend on the system parameters and on the noise sources. We then determine the cooling regime, the cooling rate, the asymptotic temperatures, and the spectrum of resonance fluorescence for experimentally relevant parameter regimes. For these parameters, we consider an electronic transition, whose linewidth allows one to perform sideband cooling, and show that the addition of an optical cavity in general does not improve the cooling efficiency. We further show that pure dephasing of the NV center's electronic transitions can lead to an improvement of the cooling efficiency.

  12. Management of a Trichophyton tonsurans outbreak in a day-care center. (United States)

    Gray, Robert M; Champagne, Caroline; Waghorn, David; Ong, Eugene; Grabczynska, Sophie A; Morris, Jill


    Trichophyton tonsurans is the leading cause of tinea capitis in the United Kingdom (UK) as well as causing tinea corporis. This organism has been linked to several outbreaks in the UK and abroad, and such outbreaks may be prolonged since T. tonsurans can be difficult to control. There remains an incomplete consensus in the literature on the optimal management of such outbreaks of this infection. Following notification that a child with T. tonsurans was identified at a day-care center in the UK, initial investigations identified nine cases of fungal infection involving children and staff over the previous 7 months. We report on the management of an outbreak of T. tonsurans tinea capitis and tinea corporis among children and staff in a day-care center. An outbreak control team with representatives from dermatology, microbiology, day-care center management, and the Health Protection Agency initiated case ascertainment by scalp inspection and brushing of all children and staff at the nursery. Two complete rounds of screening were required before the outbreak was declared over. Infection control measures included antifungal shampoo use, exclusion of identified cases for a short period, removal of shared items from the center, and enhanced decontamination of fomites. The outbreak, which lasted longer than 12 months, involved 12 children and 7 staff members. Of these, 12 cases were confirmed by positive fungal culture. T. tonsurans is difficult to manage, especially in childcare settings, but case ascertainment, appropriate treatment with oral agents, and sustained infection control measures can be effective in controlling such outbreaks.

    Mallick, P. K.


    The Center for Lightweighting Materials and Processing (CLAMP) was established in September 1998 with a grant from the Department of Energy’s Graduate Automotive Technology Education (GATE) program. The center received the second round of GATE grant in 2005 under the title “Upgrading the Center for Lightweighting Automotive Materials and Processing”. Using the two grants, the Center has successfully created 10 graduate level courses on lightweight automotive materials, integrated them into master’s and PhD programs in Automotive Systems Engineering, and offered them regularly to the graduate students in the program. In addition, the Center has created a web-based lightweight automotive materials database, conducted research on lightweight automotive materials and organized seminars/symposia on lightweight automotive materials for both academia and industry. The faculty involved with the Center has conducted research on a variety of topics related to design, testing, characterization and processing of lightweight materials for automotive applications and have received numerous research grants from automotive companies and government agencies to support their research. The materials considered included advanced steels, light alloys (aluminum, magnesium and titanium) and fiber reinforced polymer composites. In some of these research projects, CLAMP faculty have collaborated with industry partners and students have used the research facilities at industry locations. The specific objectives of the project during the current funding period (2005 – 2012) were as follows: (1) develop new graduate courses and incorporate them in the automotive systems engineering curriculum (2) improve and update two existing courses on automotive materials and processing (3) upgrade the laboratory facilities used by graduate students to conduct research (4) expand the Lightweight Automotive Materials Database to include additional materials, design case studies and make it more

  16. Alternative funding for academic medicine: experience at a Canadian Health Sciences Center. (United States)

    Rosenbaum, Paul; Shortt, S E D; Walker, D M C


    In 1994 the School of Medicine of Queen's University in Kingston, Ontario, its clinical teachers, and the three principal teaching hospitals initiated a new approach to funding, the Alternative Funding Plan, a pragmatic response to the inability of fee-for-service billing by clinical faculty to subsidize the academic mission of the health sciences center. The center was funded to provide a package of service and academic deliverables (outputs), rather than on the basis of payment for physician clinical activity (inputs). The new plan required a new governance structure representing stakeholders and raised a number of important issues: how to reconcile the preservation of physician professional autonomy with corporate responsibilities; how to gather requisite information so as to equitably allocate resources; and how to report to the Ontario Ministry of Health and Long-term Care in order to demonstrate accountability. In subsequent iterations of the agreement it was necessary to address issues of flexibility resulting from locked-in funding levels and to devise meaningful performance measures for departments and the center as a whole. The authors conclude that the Alternative Funding Plan represents a successful innovation in funding for an academic health sciences center in that it has created financial stability, as well as modest positive effects for education and research. The Ontario government hopes to replicate the model at the province's other four health sciences centers, and it may have applicability in any jurisdiction in which the costs of medical education outstrip the capacity of faculty clinical earnings.

  17. Naturally surveilled space: the design of a male drug rehabilitation center (United States)

    Permana, A. R.; Aryanti, T.; Rahmanullah, F.


    The increase of drug addicts in Indonesia has not been supported by adequate facilities, both quantitatively and qualitatively. Despite being treated in a rehabilitation center, drug addicts may still use drugs surreptitiously and put themselves in danger. Architectural design may contribute to this either positively or negatively. This article elaborates a therapeutic design of a male rehabilitation center in the borderland of Bandung city, Indonesia. Employing the notion of natural surveillance, the rehabilitation center is designed to allow continual control over attendees without them feeling suppressed. The center design uses the behavioral approach to consider both attendees’ physical and psychological comforts, as well as their security. Building masses are designed in a way that forms an inward orientation and are laid out circularly according to the therapy processes that attendees must undertake. Moreover, rooms are planned differently in response to attendees’ unique conditions and restrictive physical requirements, such as their restriction on lighting and requirement of water for treatment. The landscape uses shady trees and vegetations as natural borders to demarcate the private zone, where attendees live, from the public area, where visitors may enter. The design is intended to provide a model for a responsive drug rehabilitation center that facilitates drug addicts’ recovery.

  18. Abnormal Grief: Should We Consider a More Patient-Centered Approach? (United States)

    Moayedoddin, Babak; Markowitz, John C


    Grief, the psychological reaction to the loss of a significant other, varies complexly in its cause, experience, evolution, and prognosis. Although most bereaved individuals experience a normal grieving process, some develop complicated grief (CG) or major depressive disorder (MDD). The DSM-5, which controversially altered the nosology, recognizes grief-related major depression (GRMD) as a diagnostic subtype if a patient meets MDD criteria two weeks post bereavement. The (DSM-5) tries to distinguish between grief and MDD, but remains a symptom-based, centered approach to grief that is not patient centered. This article reviews grief in its normal and abnormal dimensions. Using an illustrative clinical case in which interpersonal psychotherapy (IPT) was employed, we discuss the need for a more patient-centered approach to treating abnormal grief, considering the patient's personal history, perceptions, experiences of bereavement, and interpersonal environment. Clinical studies need to better identify subgroups of individuals susceptible to abnormal grief and to evaluate their response to early interventions.

  20. Can a Satellite Galaxy Merger Explain the Active Past of the Galactic Center?

    CERN Document Server

    Lang, Meagan; Bogdanovic, Tamara; Amaro-Seoane, Pau; Sesana, Alberto


    Observations of the Galactic Center (GC) have accumulated a multitude of "forensic" evidence indicating that several million years ago the center of the Milky Way galaxy was teaming with starforming and accretion-powered activity -- this paints a rather different picture from the GC as we understand it today. We examine a possibility that this epoch of activity could have been triggered by the infall of a satellite galaxy into the Milky Way which began at the redshift of 10 and ended few million years ago with a merger of the Galactic supermassive black hole with an intermediate mass black hole brought in by the inspiralling satellite.

  1. Development of a Flexible Laser Hardening & Machining Center and Proof of Concept on C-45 Steel (United States)

    Bouquet, Jan; Van Camp, Dries; Vanhove, Hans; Clijsters, Stijn; Amirahmad, Mohammadi; Lauwers, Bert

    The production of hardened precision parts is conventionally done in 3 steps. Rough machining of a workpiece in soft stage is followed by a hardening step, usually a batch process, and finalized by a hard machining finishing step. To omit the inevitable time delay and loss of accuracy because of part re-clamping, these steps should be incorporated within one flexible machining center. This paper describes the development of this machining center which allowsmachining and laser hardening in one setup, followed by a proof of concept for hardening C45 steel on this setup.

  2. A knowledge continuity management program for the energy, infrastructure and knowledge systems center, Sandia National Laboratories.

    Energy Technology Data Exchange (ETDEWEB)

    Menicucci, David F.


    A growing recognition exists in companies worldwide that, when employees leave, they take with them valuable knowledge that is difficult and expensive to recreate. The concern is now particularly acute as the large ''baby boomer'' generation is reaching retirement age. A new field of science, Knowledge Continuity Management (KCM), is designed to capture and catalog the acquired knowledge and wisdom from experience of these employees before they leave. The KCM concept is in the final stages of being adopted by the Energy, Infrastructure, and Knowledge Systems Center and a program is being applied that should produce significant annual cost savings. This report discusses how the Center can use KCM to mitigate knowledge loss from employee departures, including a concise description of a proposed plan tailored to the Center's specific needs and resources.

  3. A Search for Radio Transients and Variables in the Galactic Center (United States)

    Neureuther, J. L.; Hyman, S. D.; Lazio, T. J. W.; Nord, M. E.; Kassim, N. E.


    We report on a search for radio transients in the Galactic center using a number of 327 MHz VLA observations made during the 1990's, and from a series of monthly VLA observations made during Spring and Summer 2002. A typical yield of compact sources in a given epoch is roughly 200. We have detected at least one new radio transient located only 1.1 degrees north of the Galactic center (AJ, 2002, vol. 123, pg. 1497). Other candidate sources are also presented. We use these observations to constrain the timescale(s) and nature of radio transients and variables in the Galactic center. Basic research in radio astronomy at the NRL is supported by the Office of Naval Research, and at Sweet Briar College by Research Corporation, the Jeffress Memorial Trust, and the National Science Foundation.

  4. Deterministic coupling of a single nitrogen vacancy center to a photonic crystal cavity

    Englund, Dirk; Rivoire, Kelley; Hatami, Fariba; Vuckovic, Jelena; Park, Hongkun; Lukin, Mikhail D


    We describe and experimentally demonstrate a technique for deterministic coupling between a photonic crystal (PC) nanocavity and single emitters. The technique is based on in-situ scanning of a PC cavity over a sample and allows the positioning of the cavity over a desired emitter with nanoscale resolution. The power of the technique, which we term a Scanning Cavity Microscope (SCM), is demonstrated by coupling the PC nanocavity to a single nitrogen vacancy (NV) center in diamond, an emitter system that provides optically accessible electron and nuclear spin qubits.

    Native Science Field Centers (NSFCs) were created to engage youth and adults in environmental science activities through the integration of traditional Native ways of knowing (understanding about the natural world based on centuries of observation including philosophy, worldview, cosmology, and belief systems of Indigenous peoples), Native languages, and Western science concepts. This paper focuses on the Blackfeet Native Science Field Center, the Lakota Native Science Field Center, and the Wind River Native Science Field Center. One of the long-term, overarching goals of these NSFCs was to stimulate the interest of Native American students in ways that encouraged them to pursue academic and career paths in science, technology, engineering, and mathematics (STEM) fields. A great deal can be learned from the experiences of the NSFCs in terms of effective educational strategies, as well as advantages and challenges in blending Native ways of knowing and Western scientific knowledge in an informal science education setting. Hopa Mountain—a Bozeman, Montana-based nonprofit—partnered with the Blackfeet Community College on the Blackfeet Reservation, Fremont County School District #21 on the Wind River Reservation, and Oglala Lakota College on the Pine Ridge Reservation to cooperatively establish the Native Science Field Centers. This paper presents a profile of each NSFC and highlights their program components and accomplishments.

  15. Meaning-centered psychotherapy: a form of psychotherapy for patients with cancer. (United States)

    Thomas, Lori P Montross; Meier, Emily A; Irwin, Scott A


    Caring for patients with cancer involves addressing their myriad physical, psychological, social, and spiritual needs. Although many cancer treatments focus on physical or psychological needs, few treatments specifically target the basic need for meaning and spiritual well-being in this population. This article describes the creation and evolution of a new psychotherapy devoted to these needs, a therapy termed "meaning-centered psychotherapy." In this article, a detailed description of meaning-centered psychotherapy is provided. An explanation of the current research findings related to this treatment are also offered, with information about the various group and individual treatments as well as the new expansions for use with cancer survivors or nursing staff. Overall, meaning-centered psychotherapy shows promise for enhancing meaning and spiritual well-being among patients with cancer and offers exciting possibilities for future research in other areas.

  16. A simple F-center laser spectrometer for continuous single frequency scans (United States)

    Nelson, David D., Jr.; Schiffman, Aram; Lykke, Keith R.; Nesbitt, David J.


    We report a simple and novel scheme for continuous, single frequency scanning of a commercial F-center laser without any computer interfacing. The scheme utilizes galvo tuning of the cavity length with intracavity CaF 2 Brewster plates with servo loop control of the intracavity etalon. This permits continuous tuning of the F-center frequency over 0.8 cm -1 under complete manual control, as well as arbitrarily long, concatenated scans, and trivial interfacing to a data acquisition system. This scanning spectrometer operation is demonstrated on direct absorption of atomic bromine.

  1. Report on Ten Years' Experience of Premarital Hemoglobinopathy Screening at a Center in Antalya, Southern Turkey. (United States)

    Canatan, Duran; Delibas, Serpil


    Thalassemia and hemoglobinopathies are a major public health problem in Turkey. Hemoglobinopathy prevention programs (HPPs) were started in 33 provinces situated in Thrace, Marmara, Aegean, Mediterranean and South Eastern regions of Turkey in 2003. A premarital hemoglobinopathy test is mandatory and free of charge in this program. According to the Ministry of Health reports, 46 first level hemoglobinopathy diagnostic centers were established for premarital tests. Within the last 10 years, approximately 79.0% of married individuals per year were screened by the centers. While the percentage of premarital screening tests was 30.0% of all couples in 2003, it reached 86.0% in 2013. The number of newborn with thalassemia and hemoglobinopathies were 272 in 2002 and dropped to 25 in 2013. There has been a 90.0% reduction in affected births. Our hemoglobinopathy diagnostic center was established in 2003 and licensed by the Ministry of Health in 2004. We studied a total of 89,981 blood samples from premarital tests for 10 years and the incidence of β- and α-thalassemia (β- and α-thal) trait was found to be 6.57 and 3.56%, respectively. The distribution of the most common abnormal hemoglobins (Hbs) was: Hb S (HBB: c.20A > T) (0.31%), Hb D-Los Angeles (HBB: c.364G > C) (0.15%), Hb G-Coushatta (HBB: c.68A > C) (0.06%) and Hb E (HBB: c.79G > A) (0.02%). A total of 60 couples, both carrying β-thal trait, were directed to the prenatal diagnosis (PND) center in 10 years. The premarital hemoglobinopathy screening program is running successfully at our center and other centers in Turkey.

  5. A-centers in silicon studied with hybrid density functional theory

    KAUST Repository

    Wang, Hao


    Density functional theory employing hybrid functional is used to gain fundamental insight into the interaction of vacancies with oxygen interstitials to form defects known as A-centers in silicon. We calculate the formation energy of the defect with respect to the Fermi energy for all possible charge states. It is found that the neutral and doubly negatively charged A-centers dominate. The findings are analyzed in terms of the density of states and discussed in view of previous experimental and theoretical studies.

  6. Mental health resources for LGBT collegians: a content analysis of college counseling center Web sites. (United States)

    This study content analyzed a randomly selected stratified national sample of 203 four-year United States colleges' counseling center Web sites to assess the degree to which such sites feature information and reference services for lesbian, gay, bisexual, and transgender (LGBT) collegians. Results revealed that LGBT-targeted communications were infrequent. For instance, fewer than one third of counseling center Web sites described individual counseling opportunities for LGBT students, fewer than 11% mentioned group counseling opportunities, and fewer than 6% offered a university crafted pamphlet with information about LGBT issues and resources. Findings are interpreted within the context of prior LGBT student health research.

    Although pinning centers created by irradiation presently produce the highest J{sub c}, it is probable that ultimately these will be emulated by chemical pinning centers. The best pinning centers produced by irradiation nevertheless provide guidelines for desirable morphology of chemical pinning structures. The highest J{sub c} produced earlier in textured HTS was obtained using isotropic high-energy ions produced by fission of {sup 235}U. This so-called U/n process produces pinning centers of diameter {<=} 4.5 nm, with an effective length of {approx}2.7 {mu}m. Maximum J{sub c} occurs for pinning center density of {approx}10{sup 10} cm{sup -3}. We use this as a model for desired chemical pinning centers. Our approach to introducing chemical pinning centers has been to produce precipitates within the HTS containing elements not native to the HTS, and to seek needlelike (columnar) deposits of small diameter. We report here on the formation of needlelike or columnar deposits in textured Y123 containing a dopant foreign to Y123. It serves as a demonstration that self-assembling nanometer diameter columns utilizing a dopant foreign to the HTS system are a feasible goal. These deposits, however, do not fully meet the ultimate requirements of pinning centers because the desired deposits should be smaller. The self-assembling columns formed contain titanium, are {approx}500 nm in diameter, and up to 10 {mu}m long. The size and morphology of the deposits vary with the mass of admixed Ti dopant. J{sub c} is decreased for small dopant mass. At larger dopant masses needlelike precipitates form, and J{sub c} increases again. A small range of mass of admixed Ti exists in which J{sub c} is enhanced by pinning. In the range of admixed Ti mass studied in these experiments there is a negligible effect on T{sub c}. Magnetization studies of J{sub c} are also reported.
