    1998-01-01

    Call centers are strategically and tactically important to many industries, including the healthcare industry. Call centers play a key role in acquiring and retaining customers. The ability to deliver high-quality and timely customer service without much expense is the basis for the proliferation and expansion of call centers. Call centers are unique blends of people and technology, where performance indicates combining appropriate technology tools with sound management practices built on key operational data. While the technology is fascinating, the people working in call centers and the skill of the management team ultimately make a difference to their companies.

  2. Starting a sleep center.

    Epstein, Lawrence J; Valentine, Paul S

    2010-05-01

    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.

  7. A Mission to Earth's Center

    Science.gov (United States)

    Olson, P.

    2016-12-01

    The last few decades have witnessed extraordinary progress on Earth's deep interior, particularly for Earth's core. Notable examples include seismic detection of fine structure and heterogeneity from the CMB to the depths of the inner core; improved constraints on the thermal regime and critical physical properties; direct experimental access to core pressures and temperatures; partial resolution of geomagnetic history into the deep past, new cosmochemical constraints on core formation, plus a first-order solution of the dynamo problem. Nevertheless, many fundamental questions about Earth's core remain unanswered, representing significant impediments to further understanding, not just of the Earth system, but also the interiors of other planets. A partial list of unsolved problems includes the composition of the core especially its light element inventory, the nature of heterogeneity in the core and its dynamical significance, quantifying heat and mass exchanges between core and mantle, the record of core evolution exemplified by inner core nucleation and the magnetic superchron cycle, and the role of core formation in governing Earth history. A more concerted and better-focused interdisciplinary effort is needed to resolve these long-standing problems, one that is comparable in its scale and structure to a planetary exploration mission. Such a Mission to Earth's Center would foster technological developments aimed specifically at these questions, such as seismic arrays designed for imaging the core, experimental capability for determining the phase diagram of the core, resolution of geomagnetic history into the deep past, plus next-generation dynamical models for the mantle, the core, and their interaction.

    2015-05-01

    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.

  15. Operating and Managing a Backup Control Center

    Science.gov (United States)

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

    2010-01-01

    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

    2016-01-01

    For any two points in a simple polygon P, the geodesic distance between them is the length of the shortest path contained in P that connects them. A geodesic center of a set S of sites (points) with respect to P is a point in P that minimizes the geodesic distance to its farthest site. In many realistic facility location problems, however, the facilities are constrained to lie in feasible regions. In this paper, we show how to compute the geodesic centers constrained to a set of line segment...

    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.

    2007-01-01

    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.

    Pazzi, S; Cristiani, P; Cavallini, A

    1998-02-01

    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.

  2. Rethinking exploitation: a process-centered account.

    Science.gov (United States)

    Jansen, Lynn A; Wall, Steven

    2013-12-01

    Exploitation has become an important topic in recent discussions of biomedical and research ethics. This is due in no small measure to the influence of Alan Wertheimer's path-breaking work on the subject. This paper presents some objections to Wertheimer's account of the concept. The objections attempt to show that his account places too much emphasis on outcome-based considerations and too little on process-based considerations. Building on these objections, the paper develops an alternative process-centered account of the concept. This alternative account of exploitation takes as its point of departure the broadly Kantian notion that it is wrong to use another as an instrument for the advancement of one's own ends. It sharpens this slippery notion and adds a number of refinements to it. The paper concludes by arguing that process-centered accounts of exploitation better illuminate the ethical challenges posed by research on human subjects than outcome-centered accounts.

  11. A Student-Centered Learning Model

    Directory of Open Access Journals (Sweden)

    Mihyar Hesson

    2007-01-01

    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.

    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.

  14. Validation: A Family-Centered Communication Skill.

    Science.gov (United States)

    Harvey, Pat; Ahmann, Elizabeth

    2016-01-01

    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.

    Full Text Available Digital data and service centers, such as those envisaged by the ICSU World Data System (WDS, are subject to a wide-ranging collection of requirements and constraints. Many of these requirements are traditionally difficult to assess and to measure objectively and consistently. As a solution to this problem, an approach based on a maturity model is proposed. This adds significant value not only in respect to objective assessment but also in assisting with evaluation of overlapping and competing criteria, planning of continuous improvement, and progress towards formal evaluation by accreditation authorities.

    2015-01-01

    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.

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

    2001-12-01

    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.

  1. Establishment of a world food preservation center

    Directory of Open Access Journals (Sweden)

    Wilson Charles L

    2013-01-01

    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.

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

    2002-01-01

    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.

    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.

    1978-09-30

    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.

    2015-01-01

    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.

    Although comprehensive burn care requires significant resources, patients may be treated at verified burn centers, nonverified burn centers, or other facilities due to a variety of factors. The purpose of this study was to evaluate the association between patient and injury characteristics and treatment location using a national database. We performed an analysis of all burn patients admitted to United States hospitals participating in the Healthcare Cost and Utilization Project over 2 years. Univariate and multivariate analyses were performed to identify patient and injury factors associated with the likelihood of treatment at designated burn care facilities. Definitive care facilities were categorized as American Burn Association-verified centers, nonverified burn centers, or other facilities. During the 2 years of the study, 29,971 burn patients were treated in 1,376 hospitals located in 19 participating states. A total of 6,712 (22%) patients were treated at verified centers, with 26% and 52% treated at nonverified or other facilities, respectively. Patients treated at verified centers were younger than those treated at nonverified or other facilities (33.1 years versus 33.7 years versus 41.9 years; p facilities. Published by Elsevier Inc.

    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.

    Full Text Available Aim: To evaluate the demographic and clinical parameters affecting the outcomes of ambulatory laparoscopic cholecystectomy (ALC in terms of pain, nausea, anxiety level, and satisfaction of patients in a tertiary health center. Materials and Methods: ALC was offered to 60 patients who met the inclusion criteria. Follow-up (questioning for postoperative pain or discomfort, nausea or vomiting, overall satisfaction was done by telephone contact on the same day at 22:00 p.m. and the first day after surgery at 8: 00 a.m. and by clinical examination one week after operation. 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.

    Students often enter graduate healthcare/biomedical schools with insufficient undergraduate instruction in effective writing, yet the ability to write well affects their career opportunities in health care and in scientific research. The present study was conducted to determine the value and effectiveness of instruction by faculty with expertise in teaching writing at a writing center at an academic health science center. Two separate sources of data were collected and analyzed. First, an anonymous campus-wide survey assessed students' satisfaction and utilization of the university's Writing Center. Second, a nonexperimental objective study was conducted comparing a subsample of students who used versus those who did not receive instruction at the Writing Center on quality of writing, as determined by an evaluator who was blind to students' utilization status. From the campus-wide survey, more than 90% of respondents who used the center (which was 26% of the student body) agreed that it was a valuable and effective resource. From the objective study of writing quality, students who used the Writing Center were twice as likely as students who did not to receive an A grade on the written assignment, and the blinded evaluator accurately estimated which students used the Writing Center based on the clarity of writing. The instruction at the Writing Center at our university is highly valued by students, and its value is further supported by objective evidence of efficacy. Such a center offers the opportunity to provide instruction that medical and other healthcare students increasingly need without requiring additions to existing curricula. By developing competency in writing, students prepare for scholarly pursuits, and through the process of writing, they engage critical thinking skills that can make them more attuned to narrative and more reflective and empathetic in the clinical setting.

    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.

    Neuro-oncology is a subspecialty attracting physicians from medical disciplines such as neurology, neurosurgery, pediatrics, oncology, and radiotherapy. It deals with diagnosis and management of primary brain tumors, as well as metastatic and non-metastatic neurological manifestations that frequently affect cancer patients including brain metastases, paraneoplastic syndromes and neurological complications of cancer treatment. A neuro-oncology unit was established in Davidoff Cancer Center at Rabin Medical Center. It provides a multidisciplinary team approach for management of brain tumors and services, such as expert outpatient clinics and inpatient consultations for the departments of oncology, hematology, bone marrow transplantation and other departments in the Rabin Medical Center. In addition, expert consultation is frequently provided to other hospitals that treat cancer patients with neurological manifestations. The medical disciplines that closely collaborate for the daily management of neuro-oncology patients include radiotherapy, hematology, oncology, neuro-surgery, neuro-radiology and neuro-pathology. The neuro-oncology center is also involved in clinical and laboratory research conducted in collaboration with researchers in Israel and abroad. The new service contributes substantially to the improved care of cancer patients and to the advance of research topics in the field of neuro-oncology.

    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.

    Science.gov (United States)

    Schaefer, Karen Moore; Zygmont, Dolores

    2003-01-01

    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.

    Science.gov (United States)

    Helvie, C O

    1999-01-01

    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.

    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.

    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.

    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.

  6. A possible role of chemotaxis in germinal center formation

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

    2002-01-01

    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.

    2011-06-01

    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.

    Prescription drug costs represent the fastest growing item in health care and are a driving force in rapidly increasing health care costs. Community health centers serve an indigent population with limited access to pharmaceuticals. Pharmaceutical companies sponsor patient assistance programs. These pharmacy assistance programs can be developed to facilitate the provision of needed pharmaceuticals to this vulnerable population. La Casa de Buena Salud is a rural community health center in eastern New Mexico, which has provided access to a substantial amount of pharmaceuticals to indigent patients through patient assistance programs. Cost savings potential are considerable for a community health center and for patients when a pharmacy assistance program is organized efficiently and employed systematically. Secondary benefits are derived from the entire medical community. While some community health centers currently make effective use of pharmaceutical company-sponsored pharmacy assistance programs, a comprehensive, long-term approach at a national level may be required.

    1998-01-01

    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.

    2016-01-01

    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.

    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.

    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.

    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.

    2009-01-01

    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.

    1990-01-01

    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.

    Currently, trauma center quality benchmarking is based on risk adjusted observed-expected (O/E) mortality ratios. However, failure to account for number of patients has been recently shown to produce unreliable mortality estimates, especially for low-volume centers. This study explores the effect of reliability adjustment (RA), a statistical technique developed to eliminate bias introduced by low volume on risk-adjusted trauma center benchmarking. Analysis of the National Trauma Data Bank 2010 was performed. Patients 16 years or older with blunt or penetrating trauma and an Injury Severity Score (ISS) of 9 or greater were included. Based on the statistically accepted standards of the Trauma Quality Improvement Program methodology, risk-adjusted mortality rates were generated for each center and used to rank them accordingly. Hierarchical logistic regression modeling was then performed to adjust these rates for reliability using an empiric Bayes approach. The impact of RA was examined by (1) recalculating interfacility variations in adjusted mortality rates and (2) comparing adjusted hospital mortality quintile rankings before and after RA. A total of 557 facilities (with 278,558 patients) were included. RA significantly reduced the variation in risk-adjusted mortality rates between centers from 14-fold (0.7-9.8%) to only 2-fold (4.4-9.6%) after RA. This reduction in variation was most profound for smaller centers. A total of 68 "best" hospitals and 18 "worst" hospitals based on current risk adjustment methods were reclassified after performing RA. "Reliability adjustment" dramatically reduces variations in risk-adjusted mortality arising from statistical noise, especially for lower volume centers. Moreover, the absence of RA had a profound impact on hospital performance assessment, suggesting that nearly one of every six hospitals in National Trauma Data Bank would have been inappropriately placed among the very best or very worst quintile of rankings. RA should be

    The University of California San Diego Community Women's Health Program (CWHP) has emerged as a successful and sustainable coexistence model of women's healthcare. The cornerstone of this midwifery practice is California's only in-hospital birth center. Located within the medical center, this unique and physically separate birth center has been the site for more than 4000 births. With 10% cesarean delivery and 98% breast-feeding rates, it is an exceptional example of low-intervention care. Integrating this previously freestanding birth center into an academic center has brought trials of mistrust and ineffectual communication. Education, consistent leadership, and development of multidisciplinary guidelines aided in overcoming these challenges. This collaborative model provides a structure in which residents learn to be respectful consultants and appreciate differences in medical practice. The CWHP and its Birth Center illustrates that through persistence and flexibility a collaborative model of maternity services can flourish and not only positively influence new families but also future generations of providers.

  16. A patient-centered care ethics analysis model for rehabilitation.

    2013-09-01

    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.

  17. Narrating narcolepsy--centering a side effect.

    2015-01-01

    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 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.

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

    CERN Document Server

    2017-01-01

    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....

    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.

    Transplant tourism is the term used for patients who travel abroad for transplantation. Transplant tourism has always been surrounded with controversy regarding how these organs were obtained, the donor's care after transplantation, and the recipient outcome. Many authors have found that the outcome of the recipients in transplant tourism is inferior to those transplanted in their own countries. However, most these studies were small, with the latest one including only 33 patients. Here, we describe the outcome of 93 patients who were transplanted abroad compared with local transplantation. All transplant patients who were followed up at our Nephrology Clinic from 1998 until 2008 were identified using our data base system. We selected patients transplanted from 2003 and forward because the computerized system for laboratory and electronic records began operation that year. A total of 165 patients were identified (93 in the tourist group and 72 in the local one). Transplant tourists had a higher rate of acute rejection in the first year compared with local transplantation (27.9% vs. 9.9, P=0.005), higher mean creatinine at 6 months and 1 year (120 vs. 101 micromol/L, P=0.0007, 113 vs. 98 micromol/L, P=0.008). There was no statistical difference in graft or patient survival in 1 or 2 years after transplantation. However, transplant tourist had a higher rate of cytomegalovirus infection (15.1% vs. 5.6%, P=0.05) and hepatitis C seroconversion (7.5% vs. 0%, P=0.02). Transplant tourists had a more complex posttransplantation course with higher incidence of acute rejection and infectious complications.

    The Boyce Research Initiatives and Education Foundation (BRIEF) is providing semester-long, hands-on, astronomy research experiences for students of all ages that results in their publishing peer-reviewed papers. The course in astronomy and double star research has evolved from a face-to-face learning experience with two instructors to an online - hybrid course that simultaneously supports classroom instruction at a variety of schools in the San Diego area. Currently, there are over 65 students enrolled in three community colleges, seven high schools, and one university as well as individual adult learners. Instructional experience, courseware, and supporting systems were developed and refined through experience gained in classroom settings from 2014 through 2016. Topics of instruction include Kepler's Laws, basic astrometry, properties of light, CCD imaging, use of filters for varying stellar spectral types, and how to perform research, scientific writing, and proposal preparation. Volunteer instructors were trained by taking the course and producing their own research papers. An expanded program was launched in the fall semester of 2016. Twelve papers from seven schools were produced; eight have been accepted for publication by the Journal of Double Observations (JDSO) and the remainder are in peer review. Three additional papers have been accepted by the JDSO and two more are in process papers. Three college professors and five advanced amateur astronomers are now qualified volunteer instructors. Supporting tools are provided by a BRIEF server and other online services. The server-based tools range from Microsoft Office and planetarium software to top-notch imaging programs and computational software for data reduction for each student team. Observations are performed by robotic telescopes worldwide supported by BRIEF. With this success, student demand has increased significantly. Many of the graduates of the first semester course wanted to expand their

    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

    Full Text Available We present our experience of 22 cases of emphysematous pyelonephritis (EPN treated from 1996 to 2012. Medical records were analyzed retrospectively for demographic profile, presence and duration of diabetes mellitus, and mode of clinical presentation. EPN was diagnosed based on demonstration of intra-renal gas by plain X-ray, ultrasound, and/or computed tomography (CT scan. Details of medical treatment, reason for surgical intervention, and final outcome were recorded. Univariate analysis was performed to identify risk factors for mortality and P value of less than 0.05 was taken as significant. Twenty-two cases (6 males, 16 females of EPN were diagnosed. Seven cases presented with acute pyelonephritis, seven cases with urosepsis, and the remaining eight patients with multi-organ dysfunction. CT grading of EPN was class IV in three, class III in four, class II in 14, and class I in one. All were initially managed medically with parenteral antibiotics. Ten patients needed additional surgical intervention. The overall survival rate was 86.3% (19/22. Among the risk factors analyzed higher CT grade, altered sensorium and thrombocytopenia were significantly associated with mortality. We conclude that a more conservative approach in managing EPN has become the standard of care. Patients having high CT grade of lesions (III and IV with altered sensorium and thrombocytopenia at presentation are more likely to die due to the disease and may be better managed by an aggressive surgical plan.

    2015-12-01

    The National Center for Atmospheric Research (NCAR) Research Data Archive (RDA), rda.ucar.edu, 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, http://ncarrda.blogspot.com/. How-to video tutorials are also posted on the NCAR Computational and Information Systems

    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.

    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.

  10. Towards a spin radar with Nitrogen Vacancy centers in diamond

    Ajoy, Ashok; Liu, Yixiang; Cappellaro, Paola

    2016-05-01

    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.

    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.

    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

    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.

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 astronomycenter.org 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.

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

    2013-05-01

    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:http://dx.doi.org/10.14429/dsj.63.2763

    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.

    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.

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

    Directory of Open Access Journals (Sweden)

    David H. Folz

    2014-03-01

    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.

    2012-12-01

    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.

    Clusters of imprinted genes are often controlled by an imprinting center that is necessary for allele-specific gene expression and to reprogram parent-of-origin information between generations. An imprinted domain at 15q11-q13 is responsible for both Angelman syndrome (AS) and Prader-Willi syndrome (PWS), two clinically distinct neurodevelopmental disorders. Angelman syndrome arises from the lack of maternal contribution from the locus, whereas Prader-Willi syndrome results from the absence of paternally expressed genes. In some rare cases of PWS and AS, small deletions may lead to incorrect parent-of-origin allele identity. DNA sequences common to these deletions define a bipartite imprinting center for the AS-PWS locus. The PWS-smallest region of deletion overlap (SRO) element of the imprinting center activates expression of genes from the paternal allele. The AS-SRO element generates maternal allele identity by epigenetically inactivating the PWS-SRO in oocytes so that paternal genes are silenced on the future maternal allele. Here we have investigated functional activities of the AS-SRO, the element necessary for maternal allele identity. We find that, in humans, the AS-SRO is an oocyte-specific promoter that generates transcripts that transit the PWS-SRO. Similar upstream promoters were detected in bovine oocytes. This result is consistent with a model in which imprinting centers become DNA methylated and acquire maternal allele identity in oocytes in response to transiting transcription.

    2010-01-01

    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.

    2012-12-01

    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.

    The patient-centered medical home (PCMH) model has great potential for optimizing the care of chronically ill patients, yet there is much to be learned about various implementations of this model and their impact on patient care processes and outcomes. We examined changes in patterns of health care use in a network of Federally Qualified Health Centers throughout a 9-year period of practice transformation that included recognition of all centers by the National Committee for Quality Assurance (NCQA) as Level 3 PCMH practices. We analyzed deidentified data from electronic health records for the period 2003 to 2011 to identify patterns of service use for all 4,595 patients with diabetes. We also examined a subsample of 545 patients who were in care throughout the study period to track improvement in glycated hemoglobin levels as a clinical measure over time. Through the transition to a PCMH, the mean number of encounters with outreach, diabetes educators, and psychosocial services increased for all diabetic patients; virtually all patients had visits with a primary care clinician, but the mean number of visits decreased slightly. Among patients in the subsample, mean annual levels of glycated hemoglobin decreased steadily during the 9-year study period, mainly driven by a reduction in patients having baseline levels exceeding 9%. This retrospective study conducted in a real-world setting using electronic health record data demonstrates a shift in resource use by diabetic patients from the primary care clinician to other members of the care team. The findings suggest that PCMH implementation has the potential to alter processes of care and improve outcomes of care, especially among those with higher disease burden.

    2014-05-01

    Geriatric hip fracture is a common event associated with high costs of care and often with suboptimal outcomes for the patients. Ideally, a new care model to manage geriatric hip fractures would address both quality and safety of patient care as well as the need for reduced costs of care. The geriatric fracture center model of care is one such model reported to improve both outcomes and quality of care. It is a lean business model applied to medicine. This article describes basic lean business concepts applied to geriatric fracture care and information needed to successfully implement a geriatric fracture center. It is written to assist physicians and surgeons in their efforts to implement an improved care model for their patients. Copyright © 2014 Elsevier Inc. All rights reserved.

    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.

    2011-08-01

    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.

  7. Dimensionality of organizational justice in a call center context.

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

    2012-04-01

    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.

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.

  9. Lessons Learned from an LGBTQ Senior Center: A Bronx Tale.

    Science.gov (United States)

    McGovern, Justine; Brown, Dwayne; Gasparro, Vita

    This article describes an interdisciplinary pilot study exploring the impact of LGBTQ senior centers on the lives of center members. Many LGBTQ adults face the future having experienced stigma and bias, restricted rights, and rejection from family of origin, and are now growing older without the support of a partner and adult children. As a result, older LGBTQ adults experience higher rates of depression, loneliness and isolation, and shortened life expectancy as compared to non-LGBTQ peers. Findings from focus group and key informant interviews highlight features of LGBTQ senior center experiences that can significantly improve members' quality of life. These include providing family, acceptance and a home, which can have an impact on outlook and outcomes. Moreover, findings suggest the need for re-thinking hetero-normative definitions of "community" in the context of LGBTQ aging. Beyond sharing findings from the study, suggesting a conceptual framework for deepening understanding about LGBTQ aging, and identifying lines of future inquiry, the article articulates implications for social work research, practice and education. Ultimately, the article argues that social work is well positioned to improve quality of life for this under-served population when it adopts a cultural humility stance in research, practice and education.

  11. Mergers involving academic health centers: a formidable challenge.

    Science.gov (United States)

    Pellegrini, V D

    2001-10-01

    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.

    2002-01-01

    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.

    Yu, Yang; Liang, Mangui; Wang, Zhe

    2017-01-01

    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.

    2015-12-01

    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

    For 30 years, the many diversity-related health sciences programs targeting the University of Pittsburgh undergraduate campus, school of medicine, schools of the health sciences, clinical practice plan, and medical center were run independently and remained separate within the academic health center (AHC). This lack of coordination hampered their overall effectiveness in promoting diversity and inclusion. In 2007, a group of faculty and administrators from the university and the medical center recognized the need to improve institutional diversity and to better address local health disparities. In this article, the authors describe the process of linking the efforts of these institutions in a way that would be successful locally and applicable to other academic environments. First, they engaged an independent consultant to conduct a study of the AHC's diversity climate, interviewing current and former faculty and trainees to define the problem and identify areas for improvement. Next, they created the Physician Inclusion Council to address the findings of this study and to coordinate future efforts with institutional leaders. Finally, they formed four working committees to address (1) communications and outreach, (2) cultural competency, (3) recruitment, and (4) mentoring and retention. These committees oversaw the strategic development and implementation of all diversity and inclusion efforts. Together these steps led to structural changes within the AHC and the improved allocation of resources that have positioned the University of Pittsburgh to achieve not only diversity but also inclusion and to continue to address the health disparities in the Pittsburgh community.

    Patients hospitalized in internal medicine often have unexplained clinical symptoms for which a drug origin can be considered. The prevalence of patients hospitalized for iatrogenic is estimated between 4-22%. We wanted to evaluate the diagnostic value of the regional center of pharmacovigilance to identify or confirm an iatrogenic disease in the department of internal medicine of Lille and characterize factors associated with drug-related side effect. This is a single-center prospective diagnostic study. We included all subsequent requests from the department of internal medicine with the Nord-Pas-de-Calais regional pharmacovigilance center between 2010 and 2012. The opinion of the regional pharmacovigilance centre was held on the record of the adverse drug reaction in the national pharmacovigilance database and analyzed according to the conclusion of iatrogenic used by clinicians in internal medicine (reference diagnosis) with a follow-up to June 2013. The variables relating to the patient, medication and adverse events were analyzed by binary logistic regression. We analyzed 160 contacts: 118 concordant cases, 38 false-positives (drug-related side effect retained by the regional pharmacovigilance center only), 4 false negatives. Registration in the national pharmacovigilance database had a sensitivity of 96% (95% CI [0.92 to 0.99]), a specificity of 46% (95% CI [0.38 to 0.53]), a value positive predictive of 69% (95% CI [0.62 to 0.76]), a negative predictive value of 89% (95% CI [0.84 to 0.94]) and a negative likelihood ratio of 0.1. False-positive had chronological and semiological accountabilities questionable (adjusted RR=2.1, 95% CI [1.2 to 2.8]). In our study, the regional pharmacovigilance center confirms the clinician's suspicion of drug-related side effects and helps to exclude drug-induced with a high negative predictive value.

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

    Energy Technology Data Exchange (ETDEWEB)

    Greitzer, Frank L.

    2002-09-30

    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.

    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.

    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.

    Swenson, M M; Sims, S L

    2000-03-01

    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.

  10. Wings: A New Paradigm in Human-Centered Design

    Schutte, Paul C.

    1997-01-01

    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

    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.

    2015-04-15

    Survivorship is a complicated notion because people often confuse a process of survivorship with a mythic identity of being a cancer survivor. This confusion may be a distraction to addressing the real-life struggles and challenges experienced by all people diagnosed with cancer. A more expansive perspective of survivorship, one that attends to patients' physical, psychological, social, spiritual, and existential challenges throughout a continuum of care, would be more in line with what is known empirically about people's experiences with cancer. In an effort to gain a patient-centered perspective on cancer, and one that emphasizes multiple dimensions of cancer survivorship, the author reports findings from a non-scientific social media poll (via Facebook and personal emails) in which survivors and colleagues working in the field of cancer survivorship answered the question: What does cancer survivorship mean to you? The comments are enlightening and useful for guiding the development of a patient-centered, and, thus, more comprehensive, approach to caring for people affected by cancer.

    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.

Non-random selection, teaching (TC)/non-teaching, urban (UC)/rural and small/large (LC) health care centers (HCC). A total of 33 indicators were evaluated; 15 of procedures, 9 of attitude, 3 of training, and 6 of communication. Level of uncertainty: <50% positive answers for each indicator. no collaboration. A total of 55 professionals participated (84.6% UC, 46.2% LC and 76.9% TC). Rank distribution: 13 customer care administrators, 13 nurse directors, 13 HCC directors, and 16 general practitioners. Levels of insecurity emerged from the following areas: reception of new medical professionals, injections administration, nursing weekend home calls, urgent consultations to specialists, aggressive patients, critical incidents over the agenda of the doctors, communication barriers with patients about treatment plans, and with immigrants. Clinical safety is on the agenda of the health centers. Identified areas of uncertainty are easily approachable, and are considered in the future system of accreditation of the Catalonian Government. General practitioners are more critical than directors, and teaching health care centers, rural and small HCC had a better sense of security. Copyright © 2012 Elsevier España, S.L.

    Trichomonas vaginalis infection (TVI) is one of the most common sexually transmitted diseases in the United States. We sought to determine the features of TVI in a referral-based vaginitis center, focusing on diagnosis and treatment of difficult cases. We conducted a retrospective review of all patients with TVI, based on International Classification of Diseases, Ninth Revision codes, seen at the Drexel Vaginitis Center between January 2008 and November 2013. Information collected on each subject included demographics, symptoms, examination findings, diagnostic tests, and treatment regimens. Of approximately 4000 new patient visits during our study period, 80 subjects were identified with TVI. Twenty subjects presented with known TVI, with most having clinically resistant infections. Diagnosis was confirmed by saline microscopy in 45%, OSOM rapid test in 40%, and clinical history in the remaining 15%. Treatment regimens varied: 20% received single 2-g dosing of either metronidazole or tinidazole, 50% received high-dose regimens, 20% received therapy with vaginal paromomycin, and 10% underwent desensitization for nitroimidazole allergy. Sixty subjects had newly diagnosed TVI, with 35% diagnosed by saline microscopy, 41.7% by OSOM rapid test, and 23.3% by APTIMA. Treatment regimens for these subjects included single 2-g dosing in 88.3%, high-dose regimen in 8.3%, and other formulations in the remaining 3.4%. In total, 80% of our subjects returned for follow-up; all of whom were cured. T. vaginalis infection is a rare condition in a tertiary care vaginitis center and often requires nonstandard treatments. Among those who returned for follow-up, the cure rate was 100%.

    The purpose of this study was to examine patient characteristics and outcomes in a group of consecutive patients with ruptured globe eye injuries at Kings County Hospital Center, a large, urban, level 1 trauma center. A retrospective chart review was performed to identify all patients with ruptured globe eye injuries seen between January 2009 and October 2011. Thirty-eight patients who sustained ruptured globe eye injuries from all causes were investigated for etiology and final visual outcomes. Eight eyes in which vision could be assessed were evaluated as having no light perception at presentation and three of these eyes required primary enucleation. Of the 38 eyes, orbit fractures were found in 15 eyes and an intraocular foreign body was found in six eyes. Our cohort revealed a 37.5% rate of primary enucleation in eyes with no light perception, which we believe to be a reflection of the severity of injury. All three cases were secondary to a gunshot wound. Further, our sample, although small in size, revealed a very high percentage of eyes that were ruptured secondary to violent causes compared with other studies.

    Full Text Available 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.

    2016-06-01

    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.

    To assess knowledge and comfort related to disaster preparedness and response gained and retained from a disaster medicine workshop given to Certified Specialists in Poison Information (CSPI). A pilot study with a pre-post intervention design. A Midwest Regional Poison Center. All CSPIs employed at the participating Poison Center (N = 27) were recruited. Participation ranged from 44 percent (n = 12) for the 4-month postworkshop knowledge quiz to 78 percent (n = 21) for the preworkshop survey. A disaster medicine workshop was given to the CSPIs. Quizzes and surveys were done preworkshop and then repeated at 1 week, 4 months, and 14 months postworkshop. CSPI knowledge and comfort pertaining to disaster-related calls. CSPIs' comfort levels with calls regarding major chemical or nuclear/radiation disasters significantly increased and stayed elevated during all follow-up periods [Kruskal-Wallis chi2 (3) = 13.1, p = 0.01]. The average preworkshop quiz score was 58.2 percent. A statistically significant increase in mean quiz score was demonstrated amongst preworkshop and postworkshop scores at all tested time intervals (F = 18.8, p educational competencies for CSPIs and disaster response would help to standardize this much needed education.

    2011-01-01

    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 ...

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

    Cusin, Giulia; Uzan, Jean-Philippe

    2016-01-01

    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...

    2013-09-01

    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.

    Full Text Available Objectives: There is paucity of information regarding clinical profile of hypopituitarism from India. We report the clinical profile of hypopituitarism from a tertiary center in North India. Materials and Methods: This study was carried out in patients attending our endocrine center between January 2010 and December 2011. All new patients were studied prospectively and those registered before January 2010 retrospectively. Relevant clinical, hormonal, and imaging data were collected. Dynamic testing for pituitary functions was carried out as necessary. Hormonal deficiencies were defined as per prevailing recommendations. Results: This study included 113 subjects. The mean age was 38.6 ± 17.8 years (range, 4 - 76 years. There were 78 (69% males and 35 females (31%. There were 22 subjects aged ≤18 years (childhood and adolescence and 91 adults (>18 years. Visual disturbances were the most common presenting complaint (33%, though headache was the most common symptom (81%. Fifteen percent presented with pituitary apoplexy. Tumors comprised of 84% of cases. Hypogonadism (97% was the most common abnormality seen followed by hypothyroidism (83.2%, hypoadrenalism (79.6%, growth hormone deficiency (88.1% of the 42 patients tested, and diabetes insipidus (13.3%. Panhypopituitarism was seen in 104 (92% patients. There were no cases of hypopituitarism secondary to traumatic brain injury, subarachnoid hemorrhage, central nervous system infections, or cranial irradiation to extrasellar tumors. Conclusion: The most common cause of hypopituitarism at tertiary care center is pituitary tumors and the commonest presenting complaint is visual symptoms. Panhypopituitarism is present in 92% cases.

    2008-01-01

    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...

    2016-04-25

    MCPB.py, 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. MCPB.py 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.

    Qin, M; Yi, X X

    2015-01-01

    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 ...

    2003-10-01

    The purpose of this study was to examine the experience with extremity vascular injuries of a level II suburban trauma center. A retrospective chart review was undertaken to include all patients admitted in a 6-year period with vascular injuries to the extremities. The vessels injured were identified along with the mechanism of injury. The method of repair was recorded. All associated neurologic injuries were investigated. Follow-up records, when available, were reviewed. Between January 1, 1996, and November 30, 2002, 48 patients were admitted with 56 vascular injuries to the extremities. Blunt trauma was the mechanism in 24 patients while penetrating trauma was the mechanism in the other 24 patients. The limb salvage rate was 95 per cent. Of the 28 injuries to upper extremity vessels, 24 were associated with neurologic injuries. In contrast, only 3 neurologic injuries were found in patients with lower extremity vascular injuries. In contrast to most urban centers, the distribution of vascular injuries to the extremities in a suburban setting was equally divided between blunt and penetrating injuries. The majority of functional impairment was related to neurologic injury rather than tissue ischemia from vascular injury.

    The growing consensus that improving science education and public science literacy requires the focused efforts of a wide spectrum of specialists, including scientists, provides the opportunity for national research centers to develop programs that seek to uniquely bring their science to educators and the public. At the National Center for Atmospheric Research (NCAR) in Boulder, Colorado, we have developed a multifaceted program for science education and outreach designed to bring our science to these audiences in a way that builds on our specialized expertise. Education and outreach activities at NCAR include numerous opportunities to engage with the public in informal settings. Our exhibit and tour program offers topically focused interactive activities and opportunities to learn about the science underway at the laboratory. We also hold an annual festival for children and families and lectures for the public through which science principles and content are communicated by hands-on activities, dramatic demonstrations, and rich visual media. Our web sites provide extensive resources including interactives and activities that enable students, educators, and the public to learn on their own about our science. Central to all of these informal science activities is the participation of lab scientists and staff, whose personal enthusiasm and science expertise enriches all aspects of the program for the public.

  14. HVAC systems in shopping centers as a utility business

    Energy Technology Data Exchange (ETDEWEB)

    Wolfert, J.E.

    1985-01-01

    Retail spaces in shopping centers have been noted for their low-cost and medium-quality HVAC systems. Typically, these systems are installed with minimal engineering and provided with less maintenance. There are, however, methods of providing higher quality HVAC systems for these retail spaces. One method is for the developer to provide a central plant type system and redistribute HVAC services for these spaces. The central plant system can redistribute chilled water, heated water, chilled air, heated air, tower water, electricity, or any other readily transportable energy source. With central type services, the economics are such that the individual retailer experiences no more overall cost but receives the benefits of a higher quality system. The developer has a larger investment but receives a reasonable return on this additional investment. The utilities now service a building that has a lower demand and a higher load factor. And society as a whole is presented with a facility that is considerably more energy efficient.

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

    2013-01-01

    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.

  17. Centers of excellence: a medical measurement or marketing myth?

    Science.gov (United States)

    Meyer, L C

    1996-01-01

    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.

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

    CERN Document Server

    Calzolari, Federico

    2012-01-01

    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.

    Bridges, R D; Mathews, K A

    1993-01-01

    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.

    Chronic gastritis is one of the most common findings at upper endoscopy in the general population, and chronic atrophic gastritis is epidemiologically associated with the occurrence of gastric cancer. However, the current status of diagnosis and treatment of chronic gastritis in China is unclear. A multi-center national study was performed; all patients who underwent diagnostic upper endoscopy for evaluation of gastrointestinal symptoms from 33 centers were enrolled. Data including sex, age, symptoms and endoscopic findings were prospectively recorded. Totally 8892 patients were included. At endoscopy, 4389, 3760 and 1573 patients were diagnosed to have superficial gastritis, erosive gastritis, and atrophic gastritis, respectively. After pathologic examination, it is found that atrophic gastritis, intestinal metaplasia and dysplasia were prevalent, which accounted for 25.8%, 23.6% and 7.3% of this patient population. Endoscopic features were useful for predicting pathologic atrophy (PLR = 4.78), but it was not useful for predicting erosive gastritis. Mucosal-protective agents and PPI were most commonly used medications for chronic gastritis. The present study suggests non-atrophic gastritis is the most common endoscopic finding in Chinese patients with upper GI symptoms. Precancerous lesions, including atrophy, intestinal metaplasia and dysplasia are prevalent in Chinese patients with chronic gastritis, and endoscopic features are useful for predicting pathologic atrophy.

    2015-01-01

    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.

    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.

    This study aimed to evaluate qualitatively the care offered to families for a Center of Psychosocial Atention of type I, located in Southern Region of Brazil. The Dialectical hermeneutic circle was used as a technique of data collection, a method recommended by the Fourth Generation Evaluation proposed by Guba and Lincoln. Topics such as reception, family meetings, home visits and involvement of family emerged in interviews with family members of this health service. Interviews and observations were the techniques used to collect data. The way has been consolidated to care for families in services represents a challenge for health professionals, since it entails the restructuring and formation of a reflection of all the actors involved in this process of change.

    CERN Document Server

    Yu, Qiang; Hu, Jun; Tan Chen, Kay

    2017-01-01

    This book presents neuromorphic cognitive systems from a learning and memory-centered perspective. It illustrates how to build a system network of neurons to perform spike-based information processing, computing, and high-level cognitive tasks. It is beneficial to a wide spectrum of readers, including undergraduate and postgraduate students and researchers who are interested in neuromorphic computing and neuromorphic engineering, as well as engineers and professionals in industry who are involved in the design and applications of neuromorphic cognitive systems, neuromorphic sensors and processors, and cognitive robotics. The book formulates a systematic framework, from the basic mathematical and computational methods in spike-based neural encoding, learning in both single and multi-layered networks, to a near cognitive level composed of memory and cognition. Since the mechanisms for integrating spiking neurons integrate to formulate cognitive functions as in the brain are little understood, studies of neuromo...

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

    1993-01-01

    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.

    1968-08-01

    The procedures in the selection, training and supervision of 10 nonprofessional volunteers, to provide direct therapeutic crisis services to patients in a Suicide Prevention Center are described. One year's experience indicates a high degree of proficiency achieved by the volunteer in the handling of suicidal crises. The volunteers' reactions to the program are reported. Significant problems for the agency emerged in reference to precipitous increase in size of staff communication, and for the volunteer, in stimulation of problems of identity and selfconcept. The comments are limited to agency situations involving the use of nonprofessional volunteers in regular collaboration with a professional staff. Other models, such as entirely volunteer staffed groups, must be evaluated separately.

    2006-01-01

    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.

    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......-D structures and compared with the experimental spectra. It was found that the width of the powder patterns of the weakly coupled protons recorded at g(perpendicular) is mainly determined by the histidine H(epsilon)(1) protons. Furthermore, the splitting in the outer wings of these powder patterns...

    Pitts, Lee; McNair, Ann R. (Technical Monitor)

    2002-01-01

    The ISS finally reached an operational state and exists for local and remote users. Onboard payload systems are managed by the Huntsville Operations Support Center (HOSC). Users access HOSC systems by internet protocols in support of daily operations, preflight simulation, and test. In support of this diverse user community, a modem security architecture has been implemented. The architecture has evolved over time from an isolated but open system to a system which supports local and remote access to the ISS over broad geographic regions. This has been accomplished through the use of an evolved security strategy, PKI, and custom design. Through this paper, descriptions of the migration process and the lessons learned are presented. This will include product decision criteria, rationale, and the use of commodity products in the end architecture. This paper will also stress the need for interoperability of various products and the effects of seemingly insignificant details.

    We examined the geographic distribution of patients to better understand the service area of the Sidney Kimmel Comprehensive Cancer Center at Johns Hopkins, a designated National Cancer Institute (NCI) comprehensive cancer center located in an urban center. Like most NCI cancer centers, the Sidney Kimmel Comprehensive Cancer Center serves a population beyond city limits. Urban cancer centers are expected to serve their immediate neighborhoods and to address disparities in access to specialty care. Our purpose was to learn the extent and nature of the cancer center service area. Statistical clustering of patient residence in the continental United States was assessed for all patients and by gender, cancer site, and race using SaTScan. Primary clusters detected for all cases and demographically and tumor-defined subpopulations were centered at Baltimore City and consisted of adjacent counties in Delaware, Pennsylvania, Virginia, West Virginia, New Jersey and New York, and the District of Columbia. Primary clusters varied in size by race, gender, and cancer site. Spatial analysis can provide insights into the populations served by urban cancer centers, assess centers' performance relative to their communities, and aid in developing a cancer center business plan that recognizes strengths, regional utility, and referral patterns. Today, 62 NCI cancer centers serve a quarter of the U.S. population in their immediate communities. From the Baltimore experience, we might project that the population served by these centers is actually more extensive and varies by patient characteristics, cancer site, and probably cancer center services offered.

    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.

    Patient-centered hospital units have grown out of the national trend to greater consumerism, but few of these units have been evaluated rigorously. We used a randomized controlled trial to compare patient outcomes on the Planetree Model Hospital Unit with other medical-surgical units in the hospital. Planetree patients were significantly more satisfied than controls with their hospital stay, the unit's environment and nursing care, but did not differ in ratings of physician care. Planetree patients reported more involvement in their care while hospitalized and higher satisfaction with the education they received. There were few differences between Planetree and controls in health behaviors. While Planetree patients reported better mental health status and role functioning after discharge, their health status was similar to controls after 3 to 6 months. There were no differences in length of stay and charges for the index hospitalization, readmissions or outpatient care during the following year.

  1. Improving the life science (biology) laboratory education experience: From an instructor-centered to a learner-centered educational environment

    Science.gov (United States)

    Stevens, Marcella Liffick

    The component parts of the educational experience in a freshman biology laboratory course could be improved if the knowledge, skills, and personality of the students could be integrated with the instructor's. Lack of integration of instruction with learning often results in students unwilling or unable to learn content and to transfer it to future courses. This research examined the component parts of instruction and learning for a freshman biology laboratory class and provided an alternative approach to the traditional experience in this lab. Outcome assessment revealed that students experiencing a learner-centered lab responded differently to instruction than students in the traditional lab did and expressed more of a learning orientation and awareness. Not all methods used were successful but course evaluations demonstrated an increased awareness of the learning process among students in the learner-centered lab. The alternative group indicated differences specifically directed toward learning, more often than the traditional group did.

    Chronic pain of the inguino-crural region or "pubalgia" explains the 0.5-6.2% of the consultations by athletes. Recently, areas of weakness in the posterior wall called "sports hernias," have been identified in some of these patients, capable of producing long-standing pain. Several authors use different image methods (CT, MRI, ultrasound) to identify the lesion and various techniques of repair, by open or laparoscopic approaches, have been proposed but there is no evidence about the superiority of one over others due to the difficulty for randomizing these patients. In our experience, diagnosis was based on clinical and ultrasound findings followed by laparoscopic exploration to confirm and repair the injury. The present study aims to assess the performance of our diagnostic and therapeutic management in a series of athletes affected by "pubalgia". 1450 athletes coming from the orthopedic office of a sport medicine center were evaluated. In 590 of them (414 amateur and 176 professionals) sports hernias were diagnosed through physical examination and ultrasound. We performed laparoscopic "TAPP" repair and, thirty days after, an assessment was performed to determine the evolution of pain and the degree of physical activity as a sign of the functional outcome. We used the U Mann-Whitney test for continuous scale variables and the chi-square test for dichotomous variables with p hernias. We found 84 "sport hernias" in 769 patients with previous diagnosis of adductor muscle strain (10.92%); on the other hand, in 127 (21.52%) of our patients with "sport hernias" US detected concomitant injuries of the adductor longus tendon, 7 of which merited additional surgical maneuvers (partial tenotomy). Compared with the findings of laparoscopy, ultrasound had a sensitivity of 95.42% and a specificity of 100%; the positive and negative predictive values were 100 and 99.4% respectively. No postoperative complications were reported. Only seven patients suffered recurrence of pain

    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.

  7. Local Molecular Orbitals from a Projection onto Localized Centers.

    Science.gov (United States)

    Heßelmann, Andreas

    2016-06-14

    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.

    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.

    2015-05-01

    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.

    To evaluate the success and complication rates of a single center's multidisciplinary approach to transvenous lead extraction. One university hospital. One hundred ninety-five patients scheduled for transvenous lead extraction. A multidisciplinary approach to transvenous lead extraction involving cardiac surgery, electrophysiology, perfusion, and cardiac anesthesiology. A case series of 351 lead extractions performed in 195 patients over a 42-month period. Indications, success rates, and complication rates were tracked and retrospectively evaluated and reported. Indications for lead extraction included 53.3% because of lead malfunction, 36.9% because of infection, with the remaining 9.7% from other categories such as venous stenosis. The lead extraction rate was 99.7%, with complete removal in 97.7%. The overall major complication rate was 3.08%. After an initial 1-year period of performing lead extractions, the overall major complication rate reduced to 1.23%. Transvenous lead extraction generally is a safe procedure, but not without complications. A multidisciplinary approach involving cardiac surgery, electrophysiology, and cardiac anesthesiology allows for successful management and the ability to rapidly manage major complications.

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.

    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.

  20. A person-centered approach to moral judgment.

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

    2015-01-01

    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.

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

    2012-04-01

    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.

    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.

    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.

    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.

    Full Text Available Abstract Background This report describes the utility of hypnosis for patients who presented to a Pediatric Pulmonary Center over a 30 month period. Methods Hypnotherapy was offered to 303 patients from May 1, 1998 – October 31, 2000. Patients offered hypnotherapy included those thought to have pulmonary symptoms due to psychological issues, discomfort due to medications, or fear of procedures. Improvement in symptoms following hypnosis was observed by the pulmonologist for most patients with habit cough and conversion reaction. Improvement of other conditions for which hypnosis was used was gauged based on patients' subjective evaluations. Results Hypnotherapy was associated with improvement in 80% of patients with persistent asthma, chest pain/pressure, habit cough, hyperventilation, shortness of breath, sighing, and vocal cord dysfunction. When improvement was reported, in some cases symptoms resolved immediately after hypnotherapy was first employed. For the others improvement was achieved after hypnosis was used for a few weeks. No patients' symptoms worsened and no new symptoms emerged following hypnotherapy. Conclusions Patients described in this report were unlikely to have achieved rapid improvement in their symptoms without the use of hypnotherapy. Therefore, hypnotherapy can be an important complementary therapy for patients in a pediatric practice.

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

    2010-01-01

    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.

    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.

    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.

    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.

  11. From STEM to STEAM: Toward a Human-Centered Education

    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.

    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.

    Full Text Available INTRODUCTION: Breast Cancer is the second commonest cause of cancer death in women. Almost all women survive breast cancer if it is detected before it starts to spread. The aim of the study is to analyze the demographical profile, stage of presentation, histological type, and treatment modalities of breast cancer in a tertiary care setting. METHODS: Total 1141 cases of breast cancer had been followed retrospectively from 1999 to 2006 A.D. in a tertiary care center and their patterns were analyzed. RESULTS: The mean age of presentation of breast cancer was 47.30 +/- 11.57 years in female and 59.03 +/- 14.63 in male, 31 (2.1% cases of breast cancer were male. There were 123 (10.78% stage I, 281 (24.62% stage II, 466 (40.84% stage III, and 271 (23.75% stage IV patients. Infiltrating ductal carcinoma was the commonest variety 610 (53.5%. Chemotherapy was the mainstay for treatment of breast cancer 341 (29.9% followed by surgery 287 (25.2%. CONCLUSIONS: Breast cancer trend is rising with more in late and advanced stages, mostly due to lack of awareness. Infiltrating ductal carcinoma is the commonest variety. Chemotherapy is the most commonly used modality of treatment. Male breast cancer present late and is not so uncommon. Keywords: breast cancer; chemotherapy; infiltrating ductal carcinoma; staging.

    2014-01-01

    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.

    The evidence-based use of resources for cancer care at end of life (EOL) has the potential to relieve suffering, reduce health care costs, and extend life. Internal benchmarks need to be established within communities to achieve these goals. The purpose for this study was to evaluate data within our community to determine our EOL cancer practices. A random sample of 390 patients was obtained from the 942 cancer deaths in Wicomico County, Maryland, for calendar years 2004 to 2008. General demographic, clinical event, and survival data were obtained from that sample using cancer registry and hospice databases as well as manual medical record reviews. In addition, the intensity of EOL cancer care was assessed using previously proposed indicator benchmarks. The significance of potential relationships between variables was explored using χ(2) analyses. Mean age at death was 70 years; 52% of patients were male; 34% died as a result of lung cancer. Median survival from diagnosis to death was 8.4 months with hospice admission and 5.8 months without hospice (P = .11). Four of eight intensity-of-care indicators (ie, intensive care unit [ICU] admission within last month of life, > one hospitalization within last month of life, hospital death, and hospice referral < 3 days before death) all significantly exceeded the referenced benchmarks. Hospice versus nonhospice admissions were associated (P < .001) with ICU admissions (2% v 13%) and hospital deaths (2% v 54%). These data suggest opportunities to improve community cancer center EOL care.

    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.

    The National Center for Biotechnology Information's (NCBI) Gene database (www.ncbi.nlm.nih.gov/gene) 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.

    Full Text Available OBJETIVES: To interpret the perception of the determining factors that influence the diet of a group of intern patients in a drug rehabilitation center in Concepción, Chile, during the year 2015. MATERIAL AND METHODS: Through a qualitative design with a phenomenological approach, intern patients of a drug rehabilitation facility, who fulfilled the study assigned criteria, were interviewed. The collection of data was conducted through semi structured interviews; which were validated by experts and subject to a pilot test. Nonprobability convenience sampling was performed. The sample size was determined through theoretical saturation, which was completed at the eighth interview. The results were subject to triangulation of informants, and were analyzed using the technique of discourse analysis. RESULTS: The participants identify positive and negative factors that condition their diet. They claim that having a fixed schedule is positive since this helps them to have a more organized diet. However, some stressful situations within the facilities are described as limiting factors in their mood, thus affecting their appetite and reducing their food intake. Additionally, not being with their families, especially at the beginning of the treatment, is considered a negative aspect. The lack of variety in terms of food preparation is also negative since this does not correspond to their food preferences. During the drug withdrawal stage, the intake of food containing carbohydrates of rapid absorption was increased. CONCLUSIONS: It is interpreted that the interviewees at the drug rehabilitation facility identify conditioning factors that influence their diet, which promote or inhibit food intake, and affect the attitude they present towards their diet in the drug withdrawal stage.

    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.

    AIM: To understand how work climate and related factors influence teamwork and collaboration in a large medical center. METHODS: A survey of 3462 employees was conducted to generate responses to Sexton’s Safety Attitudes Questionnaire (SAQ) to assess perceptions of work environment via a series of five-point, Likert-scaled questions. Path analysis was performed, using teamwork (TW) and collaboration (CO) as endogenous variables. The exogenous variables are effective communication (EC), safety culture (SC), job satisfaction (JS), work pressure (PR), and work climate (WC). The measurement instruments for the variables or summated subscales are presented. Reliability of each sub-scale are calculated. Alpha Cronbach coefficients are relatively strong: TW (0.81), CO (0.76), EC (0.70), SC (0.83), JS (0.91), WP (0.85), and WC (0.78). Confirmatory factor analysis was performed for each of these constructs. RESULTS: Path analysis enables to identify statistically significant predictors of two endogenous variables, teamwork and intra-organizational collaboration. Significant amounts of variance in perceived teamwork (R2 = 0.59) and in collaboration (R2 = 0.75) are accounted for by the predictor variables. In the initial model, safety culture is the most important predictor of perceived teamwork, with a β weight of 0.51, and work climate is the most significant predictor of collaboration, with a β weight of 0.84. After eliminating statistically insignificant causal paths and allowing correlated predictors1, the revised model shows that work climate is the only predictor positively influencing both teamwork (β = 0.26) and collaboration (β = 0.88). A relatively weak positive (β = 0.14) but statistically significant relationship exists between teamwork and collaboration when the effects of other predictors are simultaneously controlled. CONCLUSION: Hospital executives who are interested in improving collaboration should assess the work climate to ensure that employees are

    2012-01-01

    Several questions remain unanswered regarding the extent to which the principles and practices of patient-centered care are achievable in the context of a forensic mental health hospital. This study examined patient-centered care from the perspectives of patients and providers in a forensic mental health hospital. Patient-centered care was assessed using several measures of complementary constructs. Interviews were conducted with 30 patients and surveys were completed by 28 service providers in a forensic mental health hospital. Patients and providers shared similar views of the therapeutic milieu and recovery orientation of services; however, providers were more likely to perceive the hospital as being potentially unsafe. Overall, the findings indicated that characteristics of patient-centered care may be found within a forensic mental health hospital. The principles of patient-centered care can be integrated into service delivery in forensic mental health hospitals, though special attention to providers’ perceptions of safety is needed.

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.

    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

    2009-12-01

    The COMET® Program has developed an Environmental Satellite Resource Center (known as the ESRC), a searchable, database-driven Website that provides easy access to a wide range of useful information training materials on polar-orbiting and geostationary satellites. Primarily sponsored by the NPOESS Program and NOAA, the ESRC is a tool for users seeking reliable sources of satellite information, training, and data. First published in September 2008, and upgraded in April 2009, the site is freely available at: http://www.meted.ucar.edu/esrc. Additional contributions to the ESRC are sought and made on an ongoing basis. The ESRC was created in response to a broad community request first made in May 2006. The COMET Program was asked to develop the site to consolidate and simplify access to reliable, current, and diverse information, training materials, and data associated with environmental satellites. The ESRC currently includes over 400 significant resources from NRL, CIMSS, CIRA, NASA, VISIT, NESDIS, and EUMETSAT, and improves access to the numerous satellite resources available from COMET’s MetEd Website. The ESRC is designed as a community site where organizations and individuals around the globe can easily submit their resources via online forms by providing a small set of metadata. The ESRC supports languages other than English and multi-lingual character sets have been tested. COMET’s role is threefold: 1) maintain the site, 2) populate it with our own materials, including smaller, focused learning objects derived from our larger training modules, and 3) provide the necessary quality assurance and monitoring to ensure that all resources are appropriate and well described before being made available. Our presentation will demonstrate many of the features and functionality of searching for resources using the ESRC, and will outline the steps for users to make their own submissions. For the site to reach its full potential, submissions representing diverse

    Although school health centers (SHCs) may improve access to reproductive health care services and contraception, published data on SHC service use and reproductive health impact are limited. Reproductive health indicators among students at four urban high schools in a single building with an SHC in 2009 were compared with students in a school without an SHC, using a quasi-experimental research design (N = 2,076 students, 1,365 from SHC and 711 from comparison school). The SHC provided comprehensive reproductive health education and services, including on-site provision of hormonal contraception. Students in the SHC were more likely to report receipt of health care provider counseling and classroom education about reproductive health and a willingness to use an SHC for reproductive health services. Use of hormonal contraception measured at various time points (first sex, last sex, and ever used) was greater among students in the SHC. Most 10th-12th graders using contraception in the SHC reported receiving contraception through the SHC. Comparing students in the nonintervention school to SHC nonusers to SHC users, we found stepwise increases in receipt of education and provider counseling, willingness to use the SHC, and contraceptive use. Students with access to comprehensive reproductive health services via an SHC reported greater exposure to reproductive health education and counseling and greater use of hormonal contraception. SHCs can be an important access point to reproductive health care and a key strategy for preventing teen pregnancy. Copyright © 2015 Society for Adolescent Health and Medicine.

    2017-03-01

    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. 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. 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. 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.

    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...

    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.

    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.

    2005-03-01

    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

  7. Ethylene, a Hormone at the Center-Stage of Nodulation.

    Guinel, Frédérique C

    2015-01-01

    Nodulation is the result of a beneficial interaction between legumes and rhizobia. It is a sophisticated process leading to nutrient exchange between the two types of symbionts. In this association, within a nodule, the rhizobia, using energy provided as photosynthates, fix atmospheric nitrogen and convert it to ammonium which is available to the plant. Nodulation is recognized as an essential process in nitrogen cycling and legume crops are known to enrich agricultural soils in nitrogenous compounds. Furthermore, as they are rich in nitrogen, legumes are considered important as staple foods for humans and fodder for animals. To tightly control this association and keep it mutualistic, the plant uses several means, including hormones. The hormone ethylene has been known as a negative regulator of nodulation for almost four decades. Since then, much progress has been made in the understanding of both the ethylene signaling pathway and the nodulation process. Here I have taken a large view, using recently obtained knowledge, to describe in some detail the major stages of the process. I have not only reviewed the steps most commonly covered (the common signaling transduction pathway, and the epidermal and cortical programs), but I have also looked into steps less understood (the pre-infection step with the plant defense response, the bacterial release and the formation of the symbiosome, and nodule functioning and senescence). After a succinct review of the ethylene signaling pathway, I have used the knowledge obtained from nodulation- and ethylene-related mutants to paint a more complete picture of the role played by the hormone in nodule organogenesis, functioning, and senescence. It transpires that ethylene is at the center of this effective symbiosis. It has not only been involved in most of the steps leading to a mature nodule, but it has also been implicated in host immunity and nodule senescence. It is likely responsible for the activation of other hormonal

    Depression and obesity/overweight during pregnancy are important public health concerns, as they are frequently associated with poor birth outcomes. The Living Smart, Living Fit® (LSLF) program was an intervention program initiated in 2008 to provide comprehensive care to low-income pregnant and postpartum women with elevated body mass index (BMI) and depressive symptoms. It linked patients to clinical care coordinators trained in motivational interviewing who promoted participation in a portfolio of mental and physical wellness activities. The objective of this study was to evaluate the effectiveness of LSLF in improving depression, BMI, birth weight, and smoking status among low-income perinatal patients. Women with Patient Health Questionnaire (PHQ-9) depression scores ≥10 and/or BMI >25 kg/m(2) at their prenatal intake visit were eligible for enrollment into the LSLF program. Enrolled participants met with clinical care coordinators who encouraged engagement in a portfolio of LSLF activities that included pregnancy/family, physical health, and mental health interventions. Outcomes were measured at the 6-week postpartum visit and included change in PHQ-9 scores, change in BMI, birth weight, and change in smoking status. Of the 107 enrollees, 86% participated in some LSLF activity. Participation in pregnancy/family related activities was significantly associated with decreased PHQ-9 scores. Participation in mental health services was significantly associated with increased birth weight. No changes in BMI or smoking status were associated with LSLF involvement. The findings of this pilot study indicate that pregnant women with depression or obesity/overweight can benefit from care coordination and a portfolio of activities for mental and physical wellness. The LSLF program provides a model for delivering this patient-centered comprehensive support. Further research should include more controlled trials to better evaluate the effectiveness of LSLF intervention.

    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

    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.

    2010-11-01

    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.

  18. A review of the design and development processes of simulation for training in healthcare - A technology-centered versus a human-centered perspective.

    Persson, Johanna

    2017-01-01

    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.

    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.

  11. Beyond active learning: a case study of teaching practices in an occupation-centered curriculum.

    Science.gov (United States)

    Hooper, Barbara

    2006-01-01

    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.

    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.

    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.

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

    2016-08-01

    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.

  15. Open Access Data Centers as an Essential Partner to a Data Publication Journal

    The success of Earth System Science Data derives in part from key infrastructure: digital object identifiers (doi) and open access data centers. Our concept that a data journal should promote access and exchange through publication of reviewed data descriptions presupposed third parties to hold the data. As minimum criteria for those data centers we expected international reputation for quality of service and an active lifetime extending at least a decade into the future. We also expected modern access interfaces offering geographic, topical and parameter-based browsing - so that users could discover related holdings through an ESSD link or discover ESSD by way of links in data sets revealed through the center's browse tools - and true open access. True open access means one or two clicks from abstract in ESSD to the data itself without barriers. We started with Pangaea and CDIAC. Data providers already used these centers, the staff welcomed the ESSD initiative and all parties cooperated on doi. With this initial support ESSD proved the basic concept of data publication and demonstrated utility to a larger group of data providers, many of whom suggested additional centers. So long as those data centers met expectations for open access and quality and durability of service, ESSD agreed to collaborate. Through back-door collaborations - e.g. service on particular data sets - ESSD developed working partnerships with more than 30 data centers in 13 countries. Data centers ask to join our list. We encourage those centers to stimulate local providers to submit a data set to ESSD, thus preserving our practical data-set by data-set partnership mode. For a few data centers where national policies impose a registration step, center staff and ESSD editors created bypass access routes to facilitate anonymous reviews. For ESSD purposes, open access and doi cooperation leading to reliable curation allows a win, win, win partnership among centers, providers, and journal.

    The bank call centers of Turkey are seen as a tool of perceiving the threats and evaluating opportunities in the SWOT analysis. By the way they are evaluated as a factor of strength. However, the weaknesses of the call centers which must be taken into account in a SWOT analysis, are so various that they cannot be ignored. The weaknesses of the call centers are elaborated with this research. The ways the call centers harm the corporations or the ways they might harm are revised.

    2002-01-01

    During germinal center reactions the appearance of two specific zones is observed: the dark and the light zone. Up to now, the origin and function of these zones are poorly understood. In the framework of a stochastic and discrete model several possible pathways of zone development during germinal center reactions are investigated. The importance of the zones in the germinal center for affinity maturation, i.e. the process of antibody optimization is discussed.

    Full Text Available Abstract Examining vulnerabilities within our current healthcare system we propose borrowing two tools from the fields of engineering and design: a Reason's system approach 1 and b User-centered design 23. Both approaches are human-centered in that they consider common patterns of human behavior when analyzing systems to identify problems and generate solutions. This paper examines these two human-centered approaches in the context of healthcare. We argue that maintaining a human-centered orientation in clinical care, research, training, and governance is critical to the evolution of an effective and sustainable healthcare system.

    2014-04-01

    Few methods have been defined for evaluating the individual and collective impacts of academic research centers. In this project, with input from injury center directors, we systematically defined indicators to assess the progress and contributions of individual Injury Control Research Centers (ICRCs) and, ultimately, to monitor progress of the overall injury center program. We used several methods of deriving a list of recommended priority and supplemental indicators. This included published literature review, telephone interviews with selected federal agency staff, an e-mail survey of injury center directors, an e-mail survey of staff at the Centers for Disease Control and Prevention, a two-stage Delphi process (e-mailed), and an in-person focus group with injury center directors. We derived the final indicators from an analysis of ratings of potential indicators by center directors and CDC staff. We also examined qualitative responses to open-ended items that address conceptual and implementation issues. All currently funded ICRCs participated in at least one part of the process, resulting in a list of 27 primary indicators (some with subcomponents), 31 supplemental indicators, and multiple suggestions for using the indicators. Our results support an approach that combines standardized definitions and quantifiable indicators with qualitative reporting, which allows consideration of center distinctions and priorities. The center directors urged caution in using the indicators, given funding constraints and recognition of unique institutional environments. While focused on injury research centers, we suggest these indicators also may be useful to academic research centers of other types. © The Author(s) 2014.

    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.

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

    Directory of Open Access Journals (Sweden)

    Hesham A. Baraka

    2015-03-01

    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.

    Older adults have high obesity rates and respond well to evidence-based weight-loss programs, such as the Diabetes Prevention Program (DPP) Lifestyle intervention. The goal of this study was to determine whether a translation of the DPP Lifestyle program delivered by lay health educators and conducted in senior centers is effective in promoting weight loss among older adults. An RCT with older adults nested within senior centers. Senior centers identified lay health educators to receive training and deliver the intervention program at the senior center. Senior centers were randomized to DPP Lifestyle program or an attention control intervention (cognitive training). Senior centers (N=15) located throughout Arkansas. Participants (N=228) were obese (BMI=34.5±4.9) older (aged 71.2±6.6 years) adults able to engage in moderate exercise. Follow-up data were collected at 4 months on 93% of the original cohort between February 2009 and July 2010. A 12-session translation of the Diabetes Prevention Program Lifestyle behavioral weight-control program delivered in group sessions by trained lay health educators. Body weight was assessed by digital scale. Percentage weight loss from baseline and proportion achieving ≥5% and ≥7% weight loss were examined. Analyses were completed in March 2011. Participants attending senior centers randomized to Lifestyle lost a significantly greater percentage of baseline weight (3.8%, 95% CI=2.9%, 4.6%) than those in the control senior centers (0.2%, 95% CI= -0.6%, -0.9%) after adjusting for baseline BMI and gender (psenior centers offering the Lifestyle program, 38% lost ≥5% of baseline weight compared with 5% in the control arm (pLifestyle senior centers lost ≥7% than did control participants (3%, p=0.001).

    Olsen, D

    1996-11-01

    No uniform guidelines for operations or accreditation standards for sports medicine center were available and, at the time of this study, little information on the management and operation of sports medicine centers was available in the literature. The purpose of the study was to determine the management structure and function of selected sports medicine centers in the United States. Questionnaires were mailed to 200 randomly selected centers throughout the United State from a directory of sports medicine centers published in Physician and Sportsmedicine (1992) to gather descriptive information on eight areas, including 1) general background, 2) staffing, 3) services, facilities, and equipment, 4) billing, collections, and revenue, 5) clientele, caseloads, and referrals, 6) ownership and financing, 7) school and club outreach contracts, and 8) marketing strategies and future trends. A total of 71 surveys (35.5%) were returned in the allotted time frame. Data were analyzed using ranges, means, medians, modes, and percentages. Results yielded several conclusions about sports medicine centers. Nearly all (93%) of the centers employed physical therapists; physical therapists were clinical directors at 70.2% of centers; orthopaedists were most often medical directors; rehabilitation was the most frequently offered service (93%); physical therapy produced the highest revenue; sports injuries accounted for a mean 34.5% of patients, who were mostly recreational or high school athletes between 13-60 years of age; primary shareholders were most often physical therapists or physicians; most were involved in outreach services for schools; marketing strategies primarily involved communication with referral sources; and managed care was identified most frequently as a trend affecting the future of sports medicine centers. Findings identified common aspects of sports medicine centers and may assist in establishing guidelines for operations or accreditation of sports medicine

    2016-01-01

    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...

    2015-02-01

    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

  10. Toward a Caribbean psychology: an African-centered approach.

    Science.gov (United States)

    Sutherland, Marcia Elizabeth

    2011-01-01

    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.

    2011-10-01

    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.

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.

    2006-01-01

    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.

    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.

    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.

    A descriptive study was carried out in two subdistricts of Nong Heng and Nong Kakha, Phan Thong District, Chon Buri Province eastern Thailand with the aim to determine factors affecting health center utilization. A cross-sectional survey was conducted on 206 randomly selected households in which household head or senior person in each household was interviewed using a structured questionnaire. The study household was classified as either high or low health center utilization group on the basis of using health services more than 50% of total health services needed in each household. The results revealed that age group, sex, education, family size, and distance from household to health center were not associated with the utilization of health center, whereas occupation, economic status, knowledge and attitude towards health center and quality as well as convenience of health services were found to be associated with health center utilization. It was seemed that underutilization of health centers was multifactorial, in which some factors were related with the personality of individual whereas others were concerned with the health center itself.

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

    Directory of Open Access Journals (Sweden)

    Thair M. Hamtini

    2011-02-01

    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.

    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 (http://cdiac.esd.ornl.gov/programs/ameriflux/ ) 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).

    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.

    2016-01-01

    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.

  16. Normal form and limit cycle bifurcation of piecewise smooth differential systems with a center

    Wei, Lijun; Zhang, Xiang

    2016-07-01

    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.

    The purpose of this study was to investigate the effect of a biopsy center-a dedicated space with a dedicated ultrasound machine and technologist, staffed daily by a radiologist responsible for performing ultrasound-guided procedures only-on the rate of non-diagnostic or unsatisfactory thyroid fine-needle aspiration (FNA). Three radiologists performed FNA on 1200 nodules in 998 patients between September 2010 and November 2015. We compared rates of nondiagnostic or unsatisfactory FNA before and after implementation of a biopsy center in September 2014 as part of a quality improvement initiative. Before the establishment of our biopsy center, ultrasound-guided procedures were scheduled between diagnostic studies in the main ultrasound department and were performed by a radiologist responsible for both. Multivariate logistic regression analysis was performed to assess the effect of the biopsy center on the odds of obtaining an adequate sample. Rates of nondiagnostic or unsatisfactory FNA decreased significantly from 15.1% to 8.5% (p biopsy center. The odds of obtaining an adequate sample were higher in the biopsy center (odds ratio, 2.07; 95% CI, 1.43-3.01), even after adjusting for patient age, nodule size, the radiologist performing the procedure, and time over the study period. The implementation of a biopsy center was associated with significantly lower rates of nondiagnostic or unsatisfactory thyroid FNA, suggesting target rates of 10% or lower are achievable with quality improvement measures.

  18. Discovery of a self-trapped-electron center in alpha-TeO2

    Science.gov (United States)

    Kappers, L. A.; Gilliam, O. R.; Bartram, R. H.; Watterich, A.; Foldvari, I.

    Electron spin resonance (ESR) studies show that electron irradiation of an alpha-TeO2 single crystal followed by 330-nm UV illumination at similar to10 K generates a new spin-1/2 paramagnetic center having C-2 symmetry, like the Te lattice sites, that is attributed to a self-trapped charge on a Te. Identification is facilitated by a strong hyperfine interaction with Te-125 at a central Te site and weaker Te-125 superhyperfine interactions with three different equivalent pairs of neighboring Te cations. The irradiations also produce the diamagnetic V-O(x) center and the paramagnetic V-O(.) and V'(O) centers. From measurements of concentration changes of the paramagnetic centers due to thermal annealing of the new center it is deduced that the self-trapped charge is a self-trapped electron. It is designated as a TeO'(2) center. This assignment is consistent with its low thermal stability since it anneals quickly at temperatures above 40 K. ESR characteristics of this new center are described.

    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.

    2011-12-01

    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.

    2016-10-01

    Full Text Available Trauma is considered a “modern civilized sickness”, and its occurrence substantially affects all of society, as well as individuals. The implementation of trauma emergency systems in cities with young, prosperous, and highly mobile populations is necessary and significant. A complete trauma emergency system includes both low-level trauma centers that offer basic emergency services and high-level trauma centers that offer comprehensive services. GIS and operational research methods were used to solve the location problem associated with these centers. This study analyzed the spatial distribution characteristics of trauma demands and the candidate locations of trauma centers based on a spatial analysis and presented a hierarchical location-allocation model for low- and high-level trauma centers in Shenzhen. The response, coverage, treatment and cost capacities of the trauma center locations were considered, and an ant colony optimization was used to calculate the optimal solution. The objectives of this study were to optimize trauma center locations, improve the allocation of medical trauma resources and reduce the rate of deaths and disabilities due to trauma.

    2012-08-01

    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

    2016-04-01

    Full Text Available Background: Magnetic resonance imaging (MRI has long been considered a perfect imaging study for evaluation of shoulder pathologies despite occasional discrepancies between MR reports and arthroscopic findings. In this study we aim to evaluate impact of imaging center as an indicator of image quality on accuracy of MRI reports in diagnosis of rotator cuff tendon pathologies. Methods: We reviewed MR reports of 64 patients who underwent arthroscopy in university center hospital. MRIs were done in various centers including both university-affiliated and out-centers. All studies were reported by two radiologists in consensus unaware of the arthroscopic results or previous reports. An inter-observer agreement analysis using the kappa statistics was performed to determine consistency among imaging and surgical reports. Results: Kappa values for out-centers were as follows: 0.785 for biceps, 0.469 for suscapularis, 0.846 for supraspinatus and 0.785 for infraspinatus tendons. In university centers values were 0.799 for biceps, 0.802 for suscapularis, 0.789 for supraspinatus and 0.770 for infraspinatus tendons. Conclusion: Image reporting in university centers with proficient sequences increased accuracy of diagnosis in 3/4 of evaluated features and showed subtle decreased inter-observer agreement in 1/4 of features. Uniformity of the scanners and protocols as well as evaluation on a workstation rather than hard copies cumulatively resulted in a meaningful increase in the accuracy of the same radiologists in diagnosis of rotator cuff tendon tear.

    2011-01-01

    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. 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. 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. 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 develop not only a learner-centered paradigm, but also to facilitate a smooth curricular transition from a teacher-centered paradigm to a

    2011-12-01

    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.

    2015-01-01

    Childhood obesity is at crisis levels in the United States. Risk factors for obesity can begin as early as infancy. Approximately 12 million children up to five years of age spend about 22.5 hours per week in child care centers where they receive a significant portion of their daily nutrition. Child care center personnel may not know how to select nutritious meal and snack choices. A health sciences librarian, a child care center director and a dietitian designed an outreach program on nutrition that helped child care center teachers gain increased nutrition literacy. The teachers indicated that they gained increased personal understanding of formerly confusing nutrition issues (e.g., how to read a nutrition label and what defines a whole grain). Teachers were also able to identify aspects of web sites linked from MedlinePlus that indicated the sites served as reliable sources of health information.

    We demonstrate coupling of the zero-phonon line of individual nitrogen-vacancy centers and the modes of microring resonators fabricated in single-crystal diamond. A zero-phonon line enhancement exceeding ten-fold is estimated from lifetime measurements at cryogenic temperatures. The devices are fabricated using standard semiconductor techniques and off-the-shelf materials, thus enabling integrated diamond photonics.

  12. A fresh look at the evolution and diversification of photochemical reaction centers.

    Science.gov (United States)

    Cardona, Tanai

    2015-10-01

    In this review, I reexamine the origin and diversification of photochemical reaction centers based on the known phylogenetic relations of the core subunits, and with the aid of sequence and structural alignments. I show, for example, that the protein folds at the C-terminus of the D1 and D2 subunits of Photosystem II, which are essential for the coordination of the water-oxidizing complex, were already in place in the most ancestral Type II reaction center subunit. I then evaluate the evolution of reaction centers in the context of the rise and expansion of the different groups of bacteria based on recent large-scale phylogenetic analyses. I find that the Heliobacteriaceae family of Firmicutes appears to be the earliest branching of the known groups of phototrophic bacteria; however, the origin of photochemical reaction centers and chlorophyll synthesis cannot be placed in this group. Moreover, it becomes evident that the Acidobacteria and the Proteobacteria shared a more recent common phototrophic ancestor, and this is also likely for the Chloroflexi and the Cyanobacteria. Finally, I argue that the discrepancies among the phylogenies of the reaction center proteins, chlorophyll synthesis enzymes, and the species tree of bacteria are best explained if both types of photochemical reaction centers evolved before the diversification of the known phyla of phototrophic bacteria. The primordial phototrophic ancestor must have had both Type I and Type II reaction centers.

    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.

    Background In order to achieve success in future goals and activities, health research centers are required to identify their key success factors. Objective This study aimed to extract and rank the factors affecting the success of research centers at one of the medical universities in Iran. Methods This study is a mixed method (qualitative-quantitative) study, which was conducted between May to October in 2016. The study setting was 22 health research centers. In qualitative phase, we extracted the factors affecting the success in research centers through purposeful interviews with 10 experts of centers, and classified them into themes and sub-themes. In the quantitative phase, we prepared a questionnaire and scored and ranked the factors recognized by 54 of the study samples by Friedman test. Results Nine themes and 42 sub-themes were identified. Themes included: strategic orientation, management, human capital, support, projects, infrastructure, communications and collaboration, paradigm and innovation and they were rated respectively as components of success in research centers. Among the 42 identified factors, 10 factors were ranked respectively as the key factors of success, and included: science and technology road map, strategic plan, evaluation indexes, committed human resources, scientific evaluation of members and centers, innovation in research and implementation, financial support, capable researchers, equipment infrastructure and teamwork. Conclusion According to the results, the strategic orientation was the most important component in the success of research centers. Therefore, managers and authorities of research centers should pay more attention to strategic areas in future planning, including the science and technology road map and strategic plan.

    2010-01-01

    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.

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.

    Full Text Available The objective of the p-center problem is to locate p-centers on a network such that the maximum of the distances from each node to its nearest center is minimized. The artificial bee colony algorithm is a swarm-based meta-heuristic algorithm that mimics the foraging behavior of honey bee colonies. This study proposes a modified ABC algorithm that benefits from a variety of search strategies to balance exploration and exploitation. Moreover, random key-based coding schemes are used to solve the p-center problem effectively. The proposed algorithm is compared to state-of-the-art techniques using different benchmark problems, and computational results reveal that the proposed approach is very efficient.

    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.

    The article highlights the value of a strategic approach for the development of a primary care health centre. The method is adapted from corporate strategy: (i) analysis of the situation of the health centre and the obstacles to its development. (ii) selection of relations on which the strategy can be developed. (iii) elaboration of a system of interventions to create a cumulative development process. (iv) Illustration of the method by application to a case. The example illustrates the principles and method and highlights the importance of interpretations and choices in elaboration of a strategy, which is therefore always a unique construction. The strategic approach provides a framework that (i) provides a subject of discussion and negotiation between members of the health centre, (ii) strengthens the consistency of structural decisions, (iii) helps the health centre to overcome obstacles and initiate a development process.

    2014-01-01

    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.

    1974-01-01

    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.

  8. A Method for Estimating Potential Energy and Cost Savings for Cooling Existing Data Centers

    Energy Technology Data Exchange (ETDEWEB)

    2017-04-24

    NREL has developed a methodology to prioritize which data center cooling systems could be upgraded for better efficiency based on estimated cost savings and economics. The best efficiency results are in cool or dry climates where 'free' economizer or evaporative cooling can provide most of the data center cooling. Locations with a high cost of energy and facilities with high power usage effectiveness (PUE) are also good candidates for data center cooling system upgrades. In one case study of a major cable provider's data centers, most of the sites studied had opportunities for cost-effective cooling system upgrades with payback period of 5 years or less. If the cable provider invested in all opportunities for upgrades with payback periods of less than 15 years, it could save 27% on annual energy costs.

  9. Multiple emotions: a person-centered approach to the relationship between intergroup emotion and action orientation.

    2014-08-01

    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.

    2016-01-01

    To describe the history, clinical features and microorganisms involved in a group of adult subjects with and without septic arthritis (SA) at a tertiary care in Mexico. A cross-sectional descriptive study was conducted on 96 adults with clinical suspicion of AS in one or more joints. In all cases synovial fluid arthrocentesis and culture was performed. The comparison group subjects were culture negative. A descriptive statistical analysis and binary logistic regression model was performed between the variables associated with the development of AS. A value of P≤.05 was significant. A total of 49 out of 96 subjects had a positive culture, mostly of the monoarticular type (96%; P=.02). The knee was the most common site (61%; P=.06) and pain was the main clinical manifestation (59%; P=.001). Staphylococcus was the most common etiological agent (65%; P<.001). The risk factors revealed in the final regression model were SA the history of joint disease (OR=25; P=.03) and volume increase (OR=13.16; P=.06). Functional limitation (OR=8.54; P=.04) showed a significant risk among borderline for SA. Our results are consistent with previous studies, and can be generalized to geographical areas with similar clinical features to those observed in this study.

Several teaching-learning strategies are used, including a short slide show, interactive lectures by area experts, and student-led group discussions of scenarios based on the elements of professionalism illustrated by Miller. Use of Miller's framework and these various educational strategies yielded greater faculty satisfaction and student participation than witnessed in previous years, resulting in a deeper foundation for professional behavior development throughout the curriculum.

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

    Energy Technology Data Exchange (ETDEWEB)

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

    2012-04-16

    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.

    2004-05-01

    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(http://www.biomol.net/cariotipo/ 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

  15. Audit of a Scientific Data Center for Certification as a Trustworthy Digital Repository: A Case Study

    Science.gov (United States)

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

    2011-12-01

    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.

  16. University/Science Center Collaborations (A Science Center Perspective): Developing an Infrastructure of Partnerships with Science Centers to Support the Engagement of Scientists and Engineers in Education and Outreach for Broad Impact

    Science.gov (United States)

    Marshall, Eric

    2009-03-01

    Science centers, professional associations, corporations and university research centers share the same mission of education and outreach, yet come from ``different worlds.'' This gap may be bridged by working together to leverage unique strengths in partnership. Front-end evaluation results for the development of new resources to support these (mostly volunteer-based) partnerships elucidate the factors which lead to a successful relationship. Maintaining a science museum-scientific community partnership requires that all partners devote adequate resources (time, money, etc.). In general, scientists/engineers and science museum professionals often approach relationships with different assumptions and expectations. The culture of science centers is distinctly different from the culture of science. Scientists/engineers prefer to select how they will ultimately share their expertise from an array of choices. Successful partnerships stem from clearly defined roles and responsibilities. Scientists/engineers are somewhat resistant to the idea of traditional, formal training. Instead of developing new expertise, many prefer to offer their existing strengths and expertise. Maintaining a healthy relationship requires the routine recognition of the contributions of scientists/engineers. As professional societies, university research centers and corporations increasingly engage in education and outreach, a need for a supportive infrastructure becomes evident. Work of TryScience.org/VolTS (Volunteers TryScience), the MRS NISE Net (Nanoscale Informal Science Education Network) subcommittee, NRCEN (NSF Research Center Education Network), the IBM On Demand Community, and IEEE Educational Activities exemplify some of the pieces of this evolving infrastructure.

    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.

    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.

    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.
