Marshall Space Flight Center's Education Department is a resource for Educator, Students and Lifelong Learners. This paper will highlight the Marshall Space Flight Center's Education Department with references to other NASA Education Departments nationwide. The principal focus will be on the responsibilities of the Pre-college Education Team which is responsible for supporting K- 12 teachers highlighting how many of the NASA Pre-college Offices engage teachers and their students in better understanding NASA's inspiring missions, unique facilities, and specialized workforce to carryout these many agency-wide tasks, goals and objectives. Attendee's will learn about the Marshall Educational Alliance Teams, as well, which is responsible for using NASA's unique assets to support all types of learning. All experience and knowledge levels, all grades K-12, and teachers in these specified groupings will gain a true appreciation of what is available for them, through Marshall Space Flight Center's Education Department. An agency-wide blue directory booklet will be distributed to all attendees, for future references and related points of contact.

Parallel updating and weighting of multiple spatial maps for visual stability during whole body motion

Medendorp, W. P.

2015-01-01

It is known that the brain uses multiple reference frames to code spatial information, including eye-centered and body-centered frames. When we move our body in space, these internal representations are no longer in register with external space, unless they are actively updated. Whether the brain updates multiple spatial representations in parallel, or whether it restricts its updating mechanisms to a single reference frame from which other representations are constructed, remains an open question. We developed an optimal integration model to simulate the updating of visual space across body motion in multiple or single reference frames. To test this model, we designed an experiment in which participants had to remember the location of a briefly presented target while being translated sideways. The behavioral responses were in agreement with a model that uses a combination of eye- and body-centered representations, weighted according to the reliability in which the target location is stored and updated in each reference frame. Our findings suggest that the brain simultaneously updates multiple spatial representations across body motion. Because both representations are kept in sync, they can be optimally combined to provide a more precise estimate of visual locations in space than based on single-frame updating mechanisms.

Eternal inflation, bubble collisions, and the persistence of memory

A “bubble universe” nucleating in an eternally inflating false vacuum will experience, in the course of its expansion, collisions with an infinite number of other bubbles. In an idealized model, we calculate the rate of collisions around an observer inside a given reference bubble. We show that the collision rate violates both the homogeneity and the isotropy of the bubble universe. Each bubble has a center which can be related to “the beginning of inflation” in the parent false vacuum, and any observer not at the center will see an anisotropic bubble collision rate that peaks in the outward direction. Surprisingly, this memory of the onset of inflation persists no matter how much time elapses before the nucleation of the reference bubble.

Palliative care units (PCUs) staffed by specialty-trained physicians and nurses have been established in a number of medical centers. The purpose of this study is to review the 5-year experience of a PCU at a large, urban academic referral center. We retrospectively reviewed a prospectively collected database of all admissions to the PCU at Vanderbilt University Medical Center in the first 5 years of its existence, from 2012 through 2017. Over these 5 years, there were 3321 admissions to the PCU. No single underlying disease process accounted for the majority of the patients, but the largest single category of patients were those with malignancy, who accounted for 38% of admissions. Transfers from the intensive care unit accounted for 50% of admissions, with 43% of admissions from a hospital floor and 7% coming from the emergency department or a clinic. Median length of stay in the PCU was 3 days. In hospital deaths occurred for 50% of admitted patients, while 38% of patients were discharged from the PCU to hospice. These data show that a successful PCU is enabled by buy in from a wide variety of referring specialists and by a multidisciplinary palliative care team focused on care of the actively dying patient as well as pain and symptom management, advance care planning, and hospice referral since a large proportion of referred patients do not die in house.

This study examined the association between interparental violence (IPV), child abuse and neglect, other traumatic experiences, and children's post-traumatic stress (PTS) symptoms and explored the moderating role of family functioning in the aftermath of IPV. One hundred and twenty IPV-exposed children (53.3 % male, M age = 9.85) and parents who were referred to community mental health centers participated in the study. Combined, IPV, child abuse and neglect, and other traumatic experiences were associated with PTS symptoms. For family functioning, higher levels of parenting stress were associated with higher levels of PTS symptoms. No moderating effects were found. To understand the variability in PTS symptoms among children exposed to IPV, other traumatic and stressful experiences need to be taken into account.

Implications of an Absolute Simultaneity Theory for Cosmology and Universe Acceleration

PubMed Central

Kipreos, Edward T.

2014-01-01

An alternate Lorentz transformation, Absolute Lorentz Transformation (ALT), has similar kinematics to special relativity yet maintains absolute simultaneity in the context of a preferred reference frame. In this study, it is shown that ALT is compatible with current experiments to test Lorentz invariance only if the proposed preferred reference frame is locally equivalent to the Earth-centered non-rotating inertial reference frame, with the inference that in an ALT framework, preferred reference frames are associated with centers of gravitational mass. Applying this theoretical framework to cosmological data produces a scenario of universal time contraction in the past. In this scenario, past time contraction would be associated with increased levels of blueshifted light emissions from cosmological objects when viewed from our current perspective. The observation that distant Type Ia supernovae are dimmer than predicted by linear Hubble expansion currently provides the most direct evidence for an accelerating universe. Adjusting for the effects of time contraction on a redshift–distance modulus diagram produces a linear distribution of supernovae over the full redshift spectrum that is consistent with a non-accelerating universe.

We describe our center's initial experience with alcohol septal ablation (ASA) for the treatment of obstructive hypertrophic cardiomyopathy. The procedure, its indications, results and clinical outcomes will be addressed, as will its current position compared to surgical myectomy. To assess the results of ASA in all patients treated in the first four years of activity at our center. We retrospectively studied all consecutive and unselected patients treated by ASA between January 2009 and February 2013. In the first four years of experience 40 patients were treated in our center. In three patients (7.5%) the intervention was repeated. Procedural success was 84%. Minor complications occurred in 7.5%. Two patients received a permanent pacemaker for atrioventricular block (6% of those without previous pacemaker). The major complication rate was 5%. There were no in-hospital deaths; during clinical follow-up (22 ± 14 months) cardiovascular mortality was 2.5% and overall mortality was 5%. The results presented reflect the initial experience of our center with ASA. The success rate was high and in line with published results, but with room to improve with better patient selection. ASA was shown to be safe, with a low complication rate and no procedure-related mortality. Our experience confirms ASA as a percutaneous alternative to myectomy for the treatment of symptomatic patients with obstructive hypertrophic cardiomyopathy refractory to medical treatment.

Transverse momentum spectra of charged particles are measured by the CMS experiment at the CERN LHC in pPb collisions at , in the range and pseudorapidity in the proton-nucleon center-of-mass frame. For , the charged-particle production is asymmetric about , with smaller yield observed in the direction of the proton beam, qualitatively consistent with expectations from shadowing in nuclear parton distribution functions (nPDF). A pp reference spectrum at is obtained by interpolation from previous measurements at higher and lower center-of-mass energies. The distribution measured in pPb collisions shows an enhancement of charged particles with compared to expectations from the pp reference. The enhancement is larger than predicted by perturbative quantum chromodynamics calculations that include antishadowing modifications of nPDFs.

Are referring doctors ready for enterprise and community wide immediate image and report access?

At most medical centers film-based radiology requires that single or multiple copies of patient exams and reports be distributed for results communication. A successful picture archiving and communication system (PACS) should provide a means to improve upon this inefficient paradigm, with universal access to imagery and exam results on demand at the user's convenience. Enterprise and community-wide experience with universal PACS access is reviewed. Referring physicians were surveyed about their experience with PACS, with regard to acceptance, productivity, frequency of usage, and impact on patient care. Web audit trails were used to assess physician usage. Film printing logs were reviewed. The filmless paradigm was highly regarded and frequently used by nearly all users. Significant productivity benefits were gleaned by all of the referring physicians. Patient quality of care benefitted from more efficient communication of results. Very small quantities of film were used for printing of exams, typically for patient copies.

As the numbers of immigrant apprehensions, detentions, and deportations increase, and in context of anti-immigrant sentiment, education scholars must better contend with the way that carcerality affects undocumented student experiences. Carcerality refers to social and political systems that formally and informally promote discipline, punishment,…

Traditionally, the spatial-numerical association of response codes (SNARC) effect was presented in two-choice condition, in which only one individual reacted to both even (small) and odd (large) numbers. Few studies explored SNARC effect in a social situation. Moreover, there are many reference frames involved in SNARC effect, and it has not yet been investigated which reference frame is dominated when two participants perform the go-nogo task together. In the present study, we investigated which reference frame plays a primary role in SNARC effect when allocentric and egocentric reference frames were consistent or inconsistent in social settings. Furthermore, we explored how two actors corepresent number-space mapping interactively. Results of the two experiments demonstrated that egocentric reference frame was at work primarily when two reference frames were consistent and inconsistent. This shows that body-centered coordinate frames influence number-space mapping in social settings, and one actor may represent another actor's action and tasks.

Based on the SYMPLICITY studies and CE (Conformité Européenne) certification, renal denervation is currently applied as a novel treatment of resistant hypertension in Europe. However, information on the proportion of patients with resistant hypertension qualifying for renal denervation after a thorough work-up and treatment adjustment remains scarce. The aim of this study was to investigate the proportion of patients eligible for renal denervation and the reasons for noneligibility at 11 expert centers participating in the European Network COordinating Research on renal Denervation in treatment-resistant hypertension (ENCOReD). The analysis included 731 patients. Age averaged 61.6 years, office blood pressure at screening was 177/96 mm Hg, and the number of blood pressure-lowering drugs taken was 4.1. Specialists referred 75.6% of patients. The proportion of patients eligible for renal denervation according to the SYMPLICITY HTN-2 criteria and each center's criteria was 42.5% (95% confidence interval, 38.0%-47.0%) and 39.7% (36.2%-43.2%), respectively. The main reasons of noneligibility were normalization of blood pressure after treatment adjustment (46.9%), unsuitable renal arterial anatomy (17.0%), and previously undetected secondary causes of hypertension (11.1%). In conclusion, after careful screening and treatment adjustment at hypertension expert centers, only ≈40% of patients referred for renal denervation, mostly by specialists, were eligible for the procedure. The most frequent cause of ineligibility (approximately half of cases) was blood pressure normalization after treatment adjustment by a hypertension specialist. Our findings highlight that hypertension centers with a record in clinical experience and research should remain the gatekeepers before renal denervation is considered.

Objectives Describe the development of a competent workforce committed to providing patient-centered care to persons with dementia and/or depression and their caregivers; to report on qualitative analyses of our workforce’s case reports about their experiences; and to present lessons learned about developing and implementing a collaborative care community-based model using our new workforce that we call care coordinator assistants (CCAs). Method Sixteen CCAs were recruited and trained in person-centered care, use of mobile office, electronic medical record system, community resources, and team member support. CCAs wrote case reports quarterly that were analyzed for patient-centered care themes. Results Qualitative analysis of 73 cases using NVivo software identified six patient-centered care themes: (1) patient familiarity/understanding; (2) patient interest/engagement encouraged; (3) flexibility and continuity of care; (4) caregiver support/engagement; (5) effective utilization/integration of training; and (6) teamwork. Most frequently reported themes were patient familiarity – 91.8% of case reports included reference to patient familiarity, 67.1% included references to teamwork and 61.6% of case reports included the theme flexibility/continuity of care. CCAs made a mean number of 15.7 (SD = 15.6) visits, with most visits for coordination of care services, followed by home visits and phone visits to over 1200 patients in 12 months. Discussion Person-centered care can be effectively implemented by well-trained CCAs in the community. PMID:26666358

Recruiting practices employed by the four clinical centers participating in the Dietary Approaches to Stop Hypertension (DASH)-Sodium trial were examined to assess the most successful method of obtaining participants and to describe pertinent learning experiences gained as a result of the trial. The primary recruitment strategies employed by each center were mass mailing brochures (direct, coupon packs, or other) and mass media (advertisements in newspapers, radio, and television spots). Of 412 randomized participants, 265 (64%) were from mass distribution of brochures, 62 (15%) mass media, and 85 (21%) were prior study participants, referred by word-of-mouth, or reported coming from screening events and presentations. Although the most successful method of recruitment was mass mailing brochures, three times as many brochures were distributed to obtain similar success as in the initial DASH trial.

Wang, J.; Misra, A.; Hirth, J. P.

2011-02-01

Molecular statics and dynamics simulations were used to study the mechanisms of sliding and migration of Σ3{112} incoherent twin boundaries (ITBs) under applied shear acting in the boundary in the face-centered-cubic (fcc) metals, Ag, Cu, Pd, and Al, of varying stacking fault energies. These studies revealed that (i) ITBs can dissociate into two phase boundaries (PBs), bounding the hexagonal 9R phase, that contain different arrays of partial dislocations; (ii) the separation distance between the two PBs scales inversely with increasing stacking fault energy; (iii) for fcc metals with low stacking fault energy, one of the two PBs migrates through the collective glide of partials, referred to as the phase-boundary-migration (PBM) mechanism; (iv) for metals with high stacking energy, ITBs experience a coupled motion (migration and sliding) through the glide of interface disconnections, referred to as the interface-disconnection-glide (IDG) mechanism.

Behavioral biases when viewing multiplexed scenes: scene structure and frames of reference for inspection

PubMed Central

Stainer, Matthew J.; Scott-Brown, Kenneth C.; Tatler, Benjamin W.

2013-01-01

Where people look when viewing a scene has been a much explored avenue of vision research (e.g., see Tatler, 2009). Current understanding of eye guidance suggests that a combination of high and low-level factors influence fixation selection (e.g., Torralba et al., 2006), but that there are also strong biases toward the center of an image (Tatler, 2007). However, situations where we view multiplexed scenes are becoming increasingly common, and it is unclear how visual inspection might be arranged when content lacks normal semantic or spatial structure. Here we use the central bias to examine how gaze behavior is organized in scenes that are presented in their normal format, or disrupted by scrambling the quadrants and separating them by space. In Experiment 1, scrambling scenes had the strongest influence on gaze allocation. Observers were highly biased by the quadrant center, although physical space did not enhance this bias. However, the center of the display still contributed to fixation selection above chance, and was most influential early in scene viewing. When the top left quadrant was held constant across all conditions in Experiment 2, fixation behavior was significantly influenced by the overall arrangement of the display, with fixations being biased toward the quadrant center when the other three quadrants were scrambled (despite the visual information in this quadrant being identical in all conditions). When scenes are scrambled into four quadrants and semantic contiguity is disrupted, observers no longer appear to view the content as a single scene (despite it consisting of the same visual information overall), but rather anchor visual inspection around the four separate “sub-scenes.” Moreover, the frame of reference that observers use when viewing the multiplex seems to change across viewing time: from an early bias toward the display center to a later bias toward quadrant centers.

An analysis of reference laboratory (send out) testing: an 8-year experience in a large academic medical center.

PubMed

MacMillan, Donna; Lewandrowski, Elizabeth; Lewandrowski, Kent

2004-01-01

Utilization of outside reference laboratories for selected laboratory testing is common in the United States. However, relatively little data exist in the literature describing the scope and impact of these services. In this study, we reviewed use of reference laboratory testing at the Massachusetts General Hospital, a large urban academic medical center in Boston, Massachusetts. A retrospective review of hospital and laboratory administrative records over an 8-year period from fiscal years (FY) 1995-2002. Over the 8 years studied, reference laboratory expenses increased 4.2-fold and totaled 12.4% of the total laboratory budget in FY 2002. Total reference laboratory test volume increased 4-fold to 68,328 tests in FY 2002 but represented only 1.06% of the total test volume in the hospital. The menu of reference laboratory tests comprised 946 tests (65.7% of the hospital test menu) compared to 494 (34.3%) of tests performed in house. The average unit cost of reference laboratory tests was essentially unchanged but was approximately 13 times greater than the average unit cost in the hospital laboratory. Much of the growth in reference laboratory cost can be attributed to the addition of new molecular, genetic, and microbiological assays. Four of the top 10 tests with the highest total cost in 2002 were molecular diagnostic tests that were recently added to the test menu. Reference laboratory testing comprises a major component of hospital clinical laboratory services. Although send out tests represent a small percentage of the total test volume, these services account for the majority of the hospital laboratory test menu and a disproportionate percentage of laboratory costs.

New high resolution measurements of open and hidden charm production in proton-nucleus collisions at √{ s} = 110GeV with LHCb

2017-11-01

Open and hidden charm production in nucleus-nucleus collisions is considered as a key probe of Quark Gluon Plasma (QGP) formation. In the search of specific QGP effects, proton-nucleus collisions are used as the reference as they account for the corresponding Cold Nuclear Matter (CNM) effects. The LHCb experiment, thanks to its System for Measuring Overlap with Gas (SMOG) can be operated in a fixed target mode with the LHC beams, at an intermediate center-of-mass energy between nominal SPS and RHIC energies. In 2015, for the first time, reactions of incident LHC proton beams on noble gas targets have been recorded by the LHCb experiment at a center-of-mass energy of 110 GeV and within the center-of-mass rapidity range - 2.77

Background: Merkel cell carcinoma is a rare tumor that occurs on areas exposed to ultraviolet light. It is usually asymptomatic and it is diagnosed late often. The treatment is surgical, associated with adjuvant radiotherapy. The objective was to present the experience in the management of Merkel cell carcinoma in a reference medical center. Methods: all patients with Merkel cell carcinoma treated at the Instituto de Investigaciones Médico-Biológicas of the Universidad Veracruzana during the period 2008 to 2011 were studied. Sex, age, evolution time, tumor localization, size, metastases and treatment were analyzed. Results: of 3217 patients treated, three cases were Merkel cell carcinoma (0.09 %), their age was 52.1 ± 14.17, male predominance of 66.67 %; the evolution time was of 29.66 ± 35.36 months; the tumour localization was on inguinal region, anterior chest and left arm; the noodle size was of 6.0 ± 5.19 cm; two patients had lymph node metastases. In two cases, resection and lymphadenectomy were performed. They all received radiation therapy and chemotherapy in one case. Histologically the medium variant predominated; immunohistochemistry was positive in the three cases. One patient died ten months after the study was done. Conclusions: our experience is similar with others authors, Merkel cell carcinoma is a rare tumor, usually diagnosed late, and it has poor survival.

Planning for the Mercy Center for Breast Health.

Olivares, V Ed

2002-01-01

During the last months of 2000, administrators at the Mercy San Juan Medical Center in Carmichael, Calif., convened a steering committee to plan the Mercy Center for Breast Health. The Steering Committee was composed of the director of ancillary and support services, the oncology clinical nurse specialist, the RN manager of the oncology nursing unit, the RN surgery center manager, and me, the manager of imaging services. The committee was responsible for creating a new business with five specific objectives: to position the Center as a comprehensive diagnostic and resource center for women; to generate physician referrals to the Breast Center through various vehicles; to create awareness of the Breast Center's capabilities among area radiologists; to create awareness of the Breast Center among employees of six sister facilities; to create "brand awareness" for the Mercy Center for Breast Health among referring physicians and patients who could use competing centers in the area. The Steering Committee's charter was to design a center with a feminine touch and ambience and to provide a "one-stop shopping" experience for patients. A major component of the Breast Center is the Dianne Haselwood Resource Center, which provides patients with educational support and information. The Steering Committee brought its diverse experience and interests to bear on arranging for equipment acquisition, information and clerical systems, staffing, clinic office design, patient care and marketing. Planning the Mercy Center for Breast Health has been a positive challenge that brought together many elements of the organization and people from different departments and specialties to create a new business venture. Our charge now is to grow and to live up to our vision of offering complete breast diagnostic, education and support services in one location.

Elementary Teacher's Conceptions of Inquiry Teaching: Messages for Teacher Development

Ireland, Joseph E.; Watters, James J.; Brownlee, Jo; Lupton, Mandy

2012-02-01

This study explored practicing elementary school teacher's conceptions of teaching in ways that foster inquiry-based learning in the science curriculum (inquiry teaching). The advocacy for inquiry-based learning in contemporary curricula assumes the principle that students learn in their own way by drawing on direct experience fostered by the teacher. That students should be able to discover answers themselves through active engagement with new experiences was central to the thinking of eminent educators such as Pestalozzi, Dewey and Montessori. However, even after many years of research and practice, inquiry learning as a referent for teaching still struggles to find expression in the average teachers' pedagogy. This study drew on interview data from 20 elementary teachers. A phenomenographic analysis revealed three conceptions of teaching for inquiry learning in science in the elementary years of schooling: (a) The Experience-centered conception where teachers focused on providing interesting sensory experiences to students; (b) The Problem-centered conception where teachers focused on engaging students with challenging problems; and (c) The Question-centered conception where teachers focused on helping students to ask and answer their own questions. Understanding teachers' conceptions has implications for both the enactment of inquiry teaching in the classroom as well as the uptake of new teaching behaviors during professional development, with enhanced outcomes for engaging students in Science.

Viewer-centered and body-centered frames of reference in direct visuomotor transformations.

It has been hypothesized that the end-point position of reaching may be specified in an egocentric frame of reference. In most previous studies, however, reaching was toward a memorized target, rather than an actual target. Thus, the role played by sensorimotor transformation could not be disassociated from the role played by storage in short-term memory. In the present study the direct process of sensorimotor transformation was investigated in reaching toward continuously visible targets that need not be stored in memory. A virtual reality system was used to present visual targets in different three-dimensional (3D) locations in two different tasks, one with visual feedback of the hand and arm position (Seen Hand) and the other without such feedback (Unseen Hand). In the Seen Hand task, the axes of maximum variability and of maximum contraction converge toward the mid-point between the eyes. In the Unseen Hand task only the maximum contraction correlates with the sight-line and the axes of maximum variability are not viewer-centered but rotate anti-clockwise around the body and the effector arm during the move from the right to the left workspace. The bulk of findings from these and previous experiments support the hypothesis of a two-stage process, with a gradual transformation from viewer-centered to body-centered and arm-centered coordinates. Retinal, extra-retinal and arm-related signals appear to be progressively combined in superior and inferior parietal areas, giving rise to egocentric representations of the end-point position of reaching.

Recent suicide bombings pose the novel problem for Trauma Centers of the massive simultaneous arrival of many gravely wounded patients. We report the experience of the French-German Military Trauma Group, a Level 2 Trauma Center, in Afghanistan during the wave of suicide bombings in February 2007. Fourteen casualties were received. A first triage was carried out by the U S Army Level I group prior to evacuation. A second surgical triage was carried out with systematic ultrasound exam. Four cases (ISS>25) were re-categorized and underwent emergency surgical procedures. Suicide bombing in crowded locations near an evacuation hospital may overwhelm the medical resources of the receiving center. It has been referred to as "The Main Gate Syndrome." We introduced the novel concept of a semi-evacuation hospital or receiving center where a second surgical triage was carried out. These exceptional circumstances require open-minded flexibility, a tailored approach, and close cooperation between surgeons and anesthetists to share experience, opinions, and ideas. In the setting of mass casualties, emergency ultrasound exam was shown to be a valuable and effective tool by virtue of its mobility, reproducibility, and immediate results.

This paper outlines the main results of a number of ACTS experiments on the efficacy of using standard Internet protocols over long-delay satellite channels. These experiments have been jointly conducted by NASAs Glenn Research Center and Ohio University over the last six years. The focus of our investigations has been the impact of long-delay networks with non-zero bit-error rates on the performance of the suite of Internet protocols. In particular, we have focused on the most widely used transport protocol, the Transmission Control Protocol (TCP), as well as several application layer protocols. This paper presents our main results, as well as references to more verbose discussions of our experiments.

To assess longitudinal patterns of community health center (CHC) utilization and the effect of insurance discontinuity after Oregon's 2008 Medicaid expansion (the Oregon Experiment). We conducted a retrospective cohort study with electronic health records and Medicaid data. We divided individuals who gained Medicaid in the Oregon Experiment into those who maintained (n = 788) or lost (n = 944) insurance coverage. We compared these groups with continuously insured (n = 921) and continuously uninsured (n = 5416) reference groups for community health center utilization rates over a 36-month period. Both newly insured groups increased utilization in the first 6 months. After 6 months, use among those who maintained coverage stabilized at a level consistent with the continuously insured, whereas it returned to baseline for those who lost coverage. Individuals who maintained coverage through Oregon's Medicaid expansion increased long-term utilization of CHCs, whereas those with unstable coverage did not. This study predicts long-term increase in CHC utilization following Affordable Care Act Medicaid expansion and emphasizes the need for policies that support insurance retention.

Trial recruitment is challenging for researchers, who frequently overestimate the pool of qualified, willing participants. Little has been written about recruitment and the comparative success of recruitment strategies. We describe one center's experience with recruitment in two regional single-center clinical trials with a combined total of 1971 participants. The heart failure trial was conducted between 1999 and 2003. The asthma trial was performed between 2003 and 2006. Trial databases were queried for referral source of each individual. Data were analyzed for effectiveness of referral source using three measures: percentage of enrollment due to that source, subject commitment to the trial (retention rate), and economics (cost per enrollee). 47.8% of CHF enrollees came from computer-generated lists or from healthcare provider referrals. Average marketing cost for enrollees and completers was $29.20 and $41.96 respectively. The most economical marketing strategy was self-referral in response to flyers. Most asthma participants (53.5%) were referred from healthcare providers, mailings to lists from local healthcare institutions, or self-referred in response to flyers. Average marketing cost for enrollees and completers was $20.44 and $38.10 respectively. The most economical marketing strategy was patient mailings. Retention rates were not markedly different among referral sources in either trial. In order to be considered effective, a recruitment strategy must demonstrate a balance between response to recruitment, retention rates, and economics. Despite the differences between these two clinical trials, the most effective recruitment strategies in both trials were mailings to locally-generated, targeted lists, and referrals from healthcare providers.

Heading perception is a complex task that generally requires the integration of visual and vestibular cues. This sensory integration is complicated by the fact that these two modalities encode motion in distinct spatial reference frames (visual, eye-centered; vestibular, head-centered). Visual and vestibular heading signals converge in the primate dorsal subdivision of the medial superior temporal area (MSTd), a region thought to contribute to heading perception, but the reference frames of these signals remain unknown. We measured the heading tuning of MSTd neurons by presenting optic flow (visual condition), inertial motion (vestibular condition), or a congruent combination of both cues (combined condition). Static eye position was varied from trial to trial to determine the reference frame of tuning (eye-centered, head-centered, or intermediate). We found that tuning for optic flow was predominantly eye-centered, whereas tuning for inertial motion was intermediate but closer to head-centered. Reference frames in the two unimodal conditions were rarely matched in single neurons and uncorrelated across the population. Notably, reference frames in the combined condition varied as a function of the relative strength and spatial congruency of visual and vestibular tuning. This represents the first investigation of spatial reference frames in a naturalistic, multimodal condition in which cues may be integrated to improve perceptual performance. Our results compare favorably with the predictions of a recent neural network model that uses a recurrent architecture to perform optimal cue integration, suggesting that the brain could use a similar computational strategy to integrate sensory signals expressed in distinct frames of reference.

Understanding health care provider barriers to hospital affiliated medical fitness center facility referral: a questionnaire survey and semi structured interviews.

The purpose of this study is to understand health care provider barriers to referring patients to Medical Fitness Center Facilities within an affiliated teaching hospital system using referral of diabetic services as an example. The aims of this study include: (1) to assess health care providers' awareness and use of facilities, (2) to determine barriers to referring patients to facilities, (3) identify current and needed resources and/or changes to increase referral to facilities. A 20-item electronic survey and requests for semi-structured interviews were administered to hospital system directors and managers (n = 51). Directors and managers instructed physicians and staff to complete the survey and interviews as applicable. Perceived barriers, knowledge, utilization, and referral of patients to Medical Fitness Center Facilities were collected and examined. Descriptive statistics were generated regarding practice characteristics, provider characteristics, and referral. Of the health care providers surveyed and interviewed (n = 25) 40% indicated verbally suggesting use of facilities, 24% provided a flyer about the facilities. No respondents indicated that they directly referred patients to the facilities. However, 16% referred patients to other locations for physical activity - including their own department's management and prevention services. 20% do not refer to Medical Fitness Center Facilities or any other lifestyle programs/locations. Lack of time (92%) and lack of standard guidelines and operating procedures (88%) are barriers to referral. All respondents indicated a strong ability to refer patients to Medical Fitness Center Facilities if given education about referral programs available as well as standard clinical guidelines and protocol for delivery. The results of this study indicate that, although few healthcare providers are currently referring patients to Medical Fitness Center Facilities, health care providers with an affiliated Medical Fitness Center Facility not only want clinical standard guidelines, protocol, and training to refer patients to Medical Fitness Center Facilities, but believe they have the ability to increase referral if given these tools. The Medical Fitness Association has a unique opportunity to bridge health care providers to Medical Fitness Center Facilities by developing clinical practice guidelines in cooperation with the American Diabetes Association.

Parents experiencing early parenting difficulties often seek support through parenting programs. Characteristics of mothers seeking parenting support and information at an early parenting center in Victoria, Australia and the relationships between these factors and parenting behavior were explored using an observational measure of parent-child interaction. Participants were 43 mothers and children attending a 5-day residential parenting program at the Queen Elizabeth Centre. Maternal and sociodemographic data as well as an observational mother-child interaction task from the Nursing Child Assessment Satellite Training Parent Child Interaction Teaching scale were completed and scored on the first day of the program. Certain maternal factors and experiences were associated with observed parenting behavior. Poorer maternal sleeping quality, unplanned pregnancy and preterm birth were all associated with less optimal parenting behavior in certain domains. Findings are discussed with reference to the impact of past experiences around pregnancy and birth as well as the current context and well-being of mothers attending early parenting centers.

This paper reports the result of an analysis of wind tunnel data acquired in support of the Facility Analysis Verification & Operational Reliability (FAVOR) project. The analysis uses methods referred to collectively at Langley Research Center as the Modern Design of Experiments (MDOE). These methods quantify the total variance in a sample of wind tunnel data and partition it into explained and unexplained components. The unexplained component is further partitioned in random and systematic components. This analysis was performed on data acquired in similar wind tunnel tests executed in four different U.S. transonic facilities. The measurement environment of each facility was quantified and compared.

The first geocenter estimation results using GPS measurements

NASA Technical Reports Server (NTRS)

Malla, R. P.; Wu, S. C.

1990-01-01

The center of mass of the Earth is the natural and unambiguous origin of a geocentric satellite dynamical system. A geocentric reference frame assumes that the origin of its coordinate axes is at the geocenter, in which all relevant observations and results can be referred and in which geodynamic theories or models for the dynamic behavior of Earth can be formulated. In practice, however, a kinematically obtained terrestrial reference frame may assume an origin other than the geocenter. A fast and accurate method of determining origin offset from the geocenter is highly desirable. Global Positioning System (GPS) measurements, because of their abundance and broad distribution, provide a powerful tool to obtain this origin offset in a short period of time. Two effective strategies have been devised. Data from the first Central and South America (Casa Uno) global GPS experiment were studied to demonstrate the ability of recovering the geocenter location with present-day GPS satellites and receivers.

Improvement in Rayleigh Scattering Measurement Accuracy

Fagan, Amy F.; Clem, Michelle M.; Elam, Kristie A.

2012-01-01

Spectroscopic Rayleigh scattering is an established flow diagnostic that has the ability to provide simultaneous velocity, density, and temperature measurements. The Fabry-Perot interferometer or etalon is a commonly employed instrument for resolving the spectrum of molecular Rayleigh scattered light for the purpose of evaluating these flow properties. This paper investigates the use of an acousto-optic frequency shifting device to improve measurement accuracy in Rayleigh scattering experiments at the NASA Glenn Research Center. The frequency shifting device is used as a means of shifting the incident or reference laser frequency by 1100 MHz to avoid overlap of the Rayleigh and reference signal peaks in the interference pattern used to obtain the velocity, density, and temperature measurements, and also to calibrate the free spectral range of the Fabry-Perot etalon. The measurement accuracy improvement is evaluated by comparison of Rayleigh scattering measurements acquired with and without shifting of the reference signal frequency in a 10 mm diameter subsonic nozzle flow.

Volk, Tyler

1993-01-01

During the past several years, the NASA Program in Controlled Ecological Life Support Systems (CELSS) has continued apace with crop research and logistic, technological, and scientific strides. These include the CELSS Test Facility planned for the space station and its prototype Engineering Development Unit, soon to be active at Ames Research Center (as well as the advanced crop growth research chamber at Ames); the large environmental growth chambers and the planned human test bed facility at Johnson Space Center; the NSCORT at Purdue with new candidate crops and diverse research into the CELSS components; the gas exchange data for soy, potatoes, and wheat from Kennedy Space Center (KSC); and the high-precision gas exchange data for wheat from Utah State University (USU). All these developments, taken together, speak to the need for crop modeling as a means to connect the findings of the crop physiologists with the engineers designing the system. A need also exists for crop modeling to analyze and predict the gas exchange data from the various locations to maximize the scientific yield from the experiments. One fruitful approach employs what has been called the 'energy cascade'. Useful as a basis for CELSS crop growth experimental design, the energy cascade as a generic modeling approach for CELSS crops is a featured accomplishment in this report. The energy cascade is a major tool for linking CELSS crop experiments to the system design. The energy cascade presented here can help collaborations between modelers and crop experimenters to develop the most fruitful experiments for pushing the limits of crop productivity. Furthermore, crop models using the energy cascade provide a natural means to compare, feature for feature, the crop growth components between different CELSS experiments, for example, at Utah State University and Kennedy Space Center.

Zen Buddhist meditative practices emphasize the long-term, mindful training of attention and awareness during one's ordinary daily-life activities, the shedding of egocentric behaviors, and the skillful application of one's innate compassionate resources of insight-wisdom toward others and oneself. This review focuses on how such a comprehensive approach to training the brain could relate to a distinctive flavor of Zen: its emphasis on direct experience, with special reference to those major acute states of awakening that create deep transformations of consciousness and behavior. In Japanese, these advanced states are called kensho and satori. Ten key concepts are reviewed. They begin by distinguishing between the concentrative and receptive forms of meditation, noticing the complementary ways that they each train our normal "top-down" and "bottom-up" modes of attentive processing. Additional concepts distinguish between our two major processing pathways. The self-centered, egocentric frame of reference processes information in relation to our body (our soma) or to our mental functions (our psyche). The other-centered frame of reference processes information anonymously. Its prefix, allo- simply means "other" in Greek. Subsequent concepts consider how these useful Greek words-ego/allo, soma/psyche-correlate with the normal functional anatomy of important thalamo ↔ cortical connections. A plausible model then envisions how a triggering stimulus that captures attention could prompt the reticular nucleus to release GABA; how its selective inhibition of the dorsal thalamus could then block both our higher somatic and psychic cortical functions; so as to: (a) delete the maladaptive aspects of selfhood, while also (b) releasing the direct, all-inclusive, globally-unified experience of other. Two final concepts consider how the long-term meditative training of intuitive functions relates to certain kinds of word-free spatial tasks that involve insightful creative problem-solving.

Exploiting the gain-modulation mechanism in parieto-motor neurons: application to visuomotor transformations and embodied simulation.

PubMed

Mahé, Sylvain; Braud, Raphaël; Gaussier, Philippe; Quoy, Mathias; Pitti, Alexandre

2015-02-01

The so-called self-other correspondence problem in imitation demands to find the transformation that maps the motor dynamics of one partner to our own. This requires a general purpose sensorimotor mechanism that transforms an external fixation-point (partner's shoulder) reference frame to one's own body-centered reference frame. We propose that the mechanism of gain-modulation observed in parietal neurons may generally serve these types of transformations by binding the sensory signals across the modalities with radial basis functions (tensor products) on the one hand and by permitting the learning of contextual reference frames on the other hand. In a shoulder-elbow robotic experiment, gain-field neurons (GF) intertwine the visuo-motor variables so that their amplitude depends on them all. In situations of modification of the body-centered reference frame, the error detected in the visuo-motor mapping can serve then to learn the transformation between the robot's current sensorimotor space and the new one. These situations occur for instance when we turn the head on its axis (visual transformation), when we use a tool (body modification), or when we interact with a partner (embodied simulation). Our results defend the idea that the biologically-inspired mechanism of gain modulation found in parietal neurons can serve as a basic structure for achieving nonlinear mapping in spatial tasks as well as in cooperative and social functions.

Health professionals must be aware of the impact on parents of the birth of children with ambiguous genitalia. This study aimed to analyze the experiences and perceptions of such parents. Parents of 30 children who were evaluated in a reference center for disorders of sex development (DSD) were interviewed. The questionnaire covered the prenatal period, the moment they were told about the disorder, initial management by health professionals, and problems they experienced. Only two cases were detected during pregnancy. The news was usually given to the mother alone by pediatricians. Most parents kept it secret and avoided exposing the baby to the prejudice of others. Parents of children who were referred without sex assignment usually held a personal belief of their child's sex. Previous assignment was based on clinical examination and/or karyotype. Spreading knowledge about DSD could increase awareness of this issue, thus reducing parents' shock and societal stigma. Training of neonatal care teams is required to avoid assignment before evaluation.

The error of L5/S1 joint moment calculation in a body-centered non-inertial reference frame when the fictitious force is ignored.

In ergonomics studies, linked segment models are commonly used for estimating dynamic L5/S1 joint moments during lifting tasks. The kinematics data input to these models are with respect to an arbitrary stationary reference frame. However, a body-centered reference frame, which is defined using the position and the orientation of human body segments, is sometimes used to conveniently identify the location of the load relative to the body. When a body-centered reference frame is moving with the body, it is a non-inertial reference frame and fictitious force exists. Directly applying a linked segment model to the kinematics data with respect to a body-centered non-inertial reference frame will ignore the effect of this fictitious force and introduce errors during L5/S1 moment estimation. In the current study, various lifting tasks were performed in the laboratory environment. The L5/S1 joint moments during the lifting tasks were calculated by a linked segment model with respect to a stationary reference frame and to a body-centered non-inertial reference frame. The results indicate that applying a linked segment model with respect to a body-centered non-inertial reference frame will result in overestimating the peak L5/S1 joint moments of the coronal plane, sagittal plane, and transverse plane during lifting tasks by 78%, 2%, and 59% on average, respectively. The instant when the peak moment occurred was delayed by 0.13, 0.03, and 0.09s on average, correspondingly for the three planes. The root-mean-square errors of the L5/S1 joint moment for the three planes are 21Nm, 19Nm, and 9Nm, correspondingly. Copyright © 2013 Elsevier Ltd. All rights reserved.

Significance of the Eccentricity of the Earth's Magnetic Field for the Magnetosphere and Ionospheric Modification

Koochak, Z.; Fraser-Smith, A. C.

2016-12-01

This paper is an extension of an earlier study of the centered and eccentric dipole models of the Earth's magnetic field [Fraser-Smith, 1987]. We have used the 1980-2015 International Geomagnetic Reference Field (IGRF) Gauss coefficients to recalculate the magnetic dipole moments and magnetic pole positions for both the centered and eccentric dipoles for an additional 35 years, thus bringing them up to date. These magnetic field models play an important role in ionosphere modification, since they influence the properties of the ionosphere. However it is not widely known that the nominal origin of the Earth's magnetic field is offset from the center of the Earth by nearly 10% of the Earth's radius, which must similarly lead to an offset of some of the larger-scale modifying effects such as those associated with the magnetosphere. We describe this offset magnetic field here to help identify its effects in ionospheric modification experiments.

Nuclear effects on the transverse momentum spectra of charged particles in pPb collisions at $$\\sqrt{s_{_\\mathrm {NN}}} =5.02$$ TeV

Transverse momentum spectra of charged particles are measured by the CMS experiment at the CERN LHC in pPb collisions at √s NN = 5.02 TeV, in the range 0.4T < 120 GeV/c and pseudorapidity |η CM|<1.8 in the proton–nucleon center-of-mass frame. For p T < 10 GeV/c, the charged-particle production is asymmetric about η CM=0, with smaller yield observed in the direction of the proton beam, qualitatively consistent with expectations from shadowing in nuclear parton distribution functions (nPDF). A pp reference spectrum at √s = 5.02 TeV is obtained by interpolation from previous measurements at higher and lower center-of-mass energies.more » The pTdistribution measured in pPb collisions shows an enhancement of charged particles with p T > 20GeV/c compared to expectations from the pp reference. As a result, the enhancement is larger than predicted by perturbative quantum chromodynamics calculations that include antishadowing modifications of nPDFs.« less

The Regional Autopsy Center: The University of Alabama at Birmingham Experience.

Rates of autopsied deaths have decreased significantly for the last several decades. It may not be practical for some institutions to maintain the facilities and staffing required to perform autopsies. In recent years, the University of Alabama at Birmingham (UAB) has established contracts to perform autopsies for several regional institutions including the Alabama Department of Forensic Sciences (ADFS), the United States Veterans Affairs, the local prison system, local community hospitals, and with families for private autopsy services. Contracts and autopsy data from 2004 to 2015 were obtained and reviewed. Since 2004, the number of UAB hospital autopsies trended slightly downward. On average, UAB hospital cases comprised most yearly cases, and the ADFS was the second largest contributor of cases. Income generated from outside autopsies performed from 2006 to 2015 totaled just more than 2 million dollars, and most of the income was generated from referred ADFS cases. This study provides evidence that a centralized institution (regional autopsy center [RAC]) can provide regional autopsy service in a practical, feasible, and economically viable manner, and a RAC can benefit both the referring institutions as well as the RAC itself.

Objectives. To assess longitudinal patterns of community health center (CHC) utilization and the effect of insurance discontinuity after Oregon’s 2008 Medicaid expansion (the Oregon Experiment). Methods. We conducted a retrospective cohort study with electronic health records and Medicaid data. We divided individuals who gained Medicaid in the Oregon Experiment into those who maintained (n = 788) or lost (n = 944) insurance coverage. We compared these groups with continuously insured (n = 921) and continuously uninsured (n = 5416) reference groups for community health center utilization rates over a 36-month period. Results. Both newly insured groups increased utilization in the first 6 months. After 6 months, use among those who maintained coverage stabilized at a level consistent with the continuously insured, whereas it returned to baseline for those who lost coverage. Conclusions. Individuals who maintained coverage through Oregon’s Medicaid expansion increased long-term utilization of CHCs, whereas those with unstable coverage did not. Policy implications. This study predicts long-term increase in CHC utilization following Affordable Care Act Medicaid expansion and emphasizes the need for policies that support insurance retention. PMID:26890164

Parental physical disease is a family issue, but families' minor children are seldom considered. The current study analyzed experiences with implementation of counseling for families with physically ill parents and minor children during a European multisite pilot project. Implementation protocols of seven European partner centers collaborating in a joint research project were analyzed by Mayring's qualitative content analysis. Both an inductive approach and a deductive approach were chosen. Satisfaction of families and therapists was considered based on information from three partner centers. Satisfaction with counseling was rather high. Mentioned problems referred to aspects related to liaison partners, family-related aspects and physicians' concerns. Recommendations related to contacting families, liaising with other professions, implementing counseling together with a research project, and training. Results are integrated in the current dissemination literature. Successful implementation was mostly determined by aspects of interdisciplinary cooperation and communication, perceived relative advantage and organizational premises. With regard to this kind of innovative child-centered family mental health services, top-down and bottom-up implementation strategies should be combined, and strategies of maintenance and sustainability should be considered from the very beginning.

Gravitational mass attraction measurement for drag-free references

NASA Astrophysics Data System (ADS)

Swank, Aaron J.

Exciting new experiments in gravitational physics are among the proposed future space science missions around the world. Such future space science experiments include gravitational wave observatories, which require extraordinarily precise instruments for gravitational wave detection. In fact, future space-based gravitational wave observatories require the use of a drag free reference sensor, which is several orders of magnitude more precise than any drag free satellite launched to date. With the analysis methods and measurement techniques described in this work, there is one less challenge associated with achieving the high-precision drag-free satellite performance levels required by gravitational wave observatories. One disturbance critical to the drag-free performance is an acceleration from the mass attraction between the spacecraft and drag-free reference mass. A direct measurement of the gravitational mass attraction force is not easily performed. Historically for drag-free satellite design, the gravitational attraction properties were estimated by using idealized equations between a point mass and objects of regular geometric shape with homogeneous density. Stringent requirements are then placed on the density distribution and fabrication tolerances for the drag-free reference mass and satellite components in order to ensure that the allocated gravitational mass attraction disturbance budget is not exceeded due to the associated uncertainty in geometry and mass properties. Yet, the uncertainty associated with mass properties and geometry generate an unacceptable uncertainty in the mass attraction calculation, which make it difficult to meet the demanding drag-free performance requirements of future gravitational wave observatories. The density homogeneity and geometrical tolerances required to meet the overall drag-free performance can easily force the use of special materials or manufacturing processes, which are impractical or not feasible. The focus of this research is therefore to develop the necessary equations for the gravitational mass attraction force and gradients between two general distributed bodies. Assuming the drag-free reference mass to be a single point mass object is no longer necessary for the gravitational attraction calculations. Furthermore, the developed equations are coupled with physical measurements in order to eliminate the mass attraction uncertainty associated with mass properties. The mass attraction formula through a second order expansion consists of the measurable quantifies of mass, mass center, and moment of inertia about the mass center. Thus, the gravitational self-attraction force on the drag free reference due to the satellite can be indirectly measured. By incorporating physical measurements into the mass attraction calculation, the uncertainty in the density distribution as well as geometrical variations due to the manufacturing process are included in the analysis. For indirect gravitational mass attraction measurements, the corresponding properties of mass, mass center, and moment of inertia must be precisely determined for the proof mass and satellite components. This work focuses on the precision measurement of the moment of inertia for the drag-free test mass. Presented here is the design of a new moment of inertia measurement apparatus utilizing a five-wire torsion pendulum design. The torsion pendulum is utilized to measure the moment of inertia tensor for a prospective drag-free test mass geometry. The measurement results presented indicate the prototype five-wire torsion has matched current state of the art precision. With only minimal work to reduce laboratory environmental disturbances, the apparatus has the prospect of exceeding state of the art precision by almost an order of magnitude. In addition, the apparatus is shown to be capable of measuring the mass center offset from the geometric center to a level better than typical measurement devices. Although the pendulum was not originally designed for mass center measurements, preliminary results indicate an apparatus with a similar design may have the potential of achieving state of the art precision.

The formation and certification of Primary Stroke Centers has progressed rapidly since the Brain Attack Coalition's original recommendations in 2000. The purpose of this article is to revise and update our recommendations for Primary Stroke Centers to reflect the latest data and experience. We conducted a literature review using MEDLINE and PubMed from March 2000 to January 2011. The review focused on studies that were relevant for acute stroke diagnosis, treatment, and care. Original references as well as meta-analyses and other care guidelines were also reviewed and included if found to be valid and relevant. Levels of evidence were added to reflect current guideline development practices. Based on the literature review and experience at Primary Stroke Centers, the importance of some elements has been further strengthened, and several new areas have been added. These include (1) the importance of acute stroke teams; (2) the importance of Stroke Units with telemetry monitoring; (3) performance of brain imaging with MRI and diffusion-weighted sequences; (4) assessment of cerebral vasculature with MR angiography or CT angiography; (5) cardiac imaging; (6) early initiation of rehabilitation therapies; and (7) certification by an independent body, including a site visit and disease performance measures. Based on the evidence, several elements of Primary Stroke Centers are particularly important for improving the care of patients with an acute stroke. Additional elements focus on imaging of the brain, the cerebral vasculature, and the heart. These new elements may improve the care and outcomes for patients with stroke cared for at a Primary Stroke Center.

Despite proof of voluntary counseling and testing (VCT) effectiveness in HIV disease prevention and management, there are limited reports on experience with pre- and post-HIV-test counseling in developing countries. In view of this, we aimed to bring to the fore the voluntary counseling and testing experience at a tertiary healthcare center. The present study was conducted at the voluntary counseling and testing center of a tertiary healthcare center and the National HIV Reference Center. Participants were 1169 men and 581 females attending the VCT clinic from February 2005 to March 2006. Odds ratios were calculated for each of the variable to analyze the strength of association with HIV sero-status. Out of 1750 patients, 322 (27.5%) males and 156 females (26.9%) tested HIV-positive. HIV-sero-positivity was observed to be associated to participant age (approximately 1.5 for 25-44 yrs age group), marital status (2.3 times in married patients), primary or lower education level (1.5 times), citing spouse death/HIV-infected spouse as the reason for seeking VCT (2.2 times) and reporting a history of risk behavior as reason for getting tested. This study aims to evaluate the effectiveness of existing client initiated voluntary counseling and testing facility in the light of a recent recommendation by WHO/UNAIDS for the implementation of provider initiated voluntary counseling services. Through this study, we could also highlight socio-demographic factors, like education and age, and reasons stated by participants for seeking VCT, which were associated with HIV-positive status and put an individual at a higher risk of HIV infection.

Background The US Centers for Disease Control and Prevention ensured adequate performance of the routine triglycerides methods used in Japan by a chromotropic acid reference measurement procedure used by the Centers for Disease Control and Prevention lipid standardization programme as a reference point. We examined standardized data to clarify the performance of routine triglycerides methods. Methods The two routine triglycerides methods were the fluorometric method of Kessler and Lederer and the enzymatic method. The methods were standardized using 495 Centers for Disease Control and Prevention reference pools with 98 different concentrations ranging between 0.37 and 5.15 mmol/L in 141 survey runs. The triglycerides criteria for laboratories which perform triglycerides analyses are used: accuracy, as bias ≤5% from the Centers for Disease Control and Prevention reference value and precision, as measured by CV, ≤5%. Results The correlation of the bias of both methods to the Centers for Disease Control and Prevention reference method was: y (%bias) = 0.516 × (Centers for Disease Control and Prevention reference value) -1.292 ( n = 495, R 2  = 0.018). Triglycerides bias at medical decision points of 1.13, 1.69 and 2.26 mmol/L was -0.71%, -0.42% and -0.13%, respectively. For the combined precision, the equation y (CV) = -0.398 × (triglycerides value) + 1.797 ( n = 495, R 2  = 0.081) was used. Precision was 1.35%, 1.12% and 0.90%, respectively. It was shown that triglycerides measurements at Osaka were stable for 36 years. Conclusions The epidemiologic laboratory in Japan met acceptable accuracy goals for 88.7% of all samples, and met acceptable precision goals for 97.8% of all samples measured through the Centers for Disease Control and Prevention lipid standardization programme and demonstrated stable results for an extended period of time.

Effects of head orientation and lateral body tilt on egocentric coding: cognitive and sensory-motor accuracy.

PubMed

Prieur, J-M; Bourdin, C; Sarès, F; Vercher, J-L

2006-01-01

A major issue in motor control studies is to determine whether and how we use spatial frames of reference to organize our spatially oriented behaviors. In previous experiments we showed that simulated body tilt during off-axis rotation affected the performance in verbal localization and manual pointing tasks. It was hypothesized that the observed alterations were at least partly due to a change in the orientation of the egocentric frame of reference, which was indeed centered on the body but aligned with the gravitational vector. The present experiments were designed to test this hypothesis in a situation where no inertial constraints (except the usual gravitational one) exist and where the orientation of the body longitudinal z-axis was not aligned with the direction of the gravity. Eleven subjects were exposed to real static body tilt and were required to verbally localize (experiment 1) and to point as accurately as possible towards (experiment 2) memorized visual targets, in two conditions, Head-Free and Head-Fixed conditions. Results show that the performance was only affected by real body tilt in the localization task performed when the subject's head was tilted relative to the body. Thus, dissociation between gravity and body longitudinal z-axis alone is not responsible for localization nor for pointing errors. Therefore, the egocentric frame of reference seems independent from the orientation of the gravity with regard to body z-axis as expected from our previous studies. Moreover, the use of spatial referentials appears to be less mandatory than expected for pointing movements (motor task) than for localization task (cognitive task).

Gaucher disease (GD) is a genetic disease caused by glucocerebrosidase deficiency. GD is treated by enzyme replacement therapy (ERT) with imiglucerase, a high-cost drug provided by the Brazilian Ministry of Health (BMH). This study reports the implementation of the BMH guidelines for GD in the southernmost state of the country. We review the clinical and laboratorial data for patients seen at the reference center for GD from Rio Grande do Sul, Brazil (July 2003 to June 2006). Twenty-five patients were included in this study. At baseline, 19/20 were on ERT (mean dosage of imiglucerase = 51.8 U/kg/infusion), 3/17 presented anemia, and 5/16 thrombocytopenia. The amount of imiglucerase prescribed to these patients was adjusted according to the guidelines in July 2003; out of them, 18 were receiving ERT in the reference center at month 36 (mean dosage of imiglucerase = 27.5 U/kg/infusion), 2/18 presented anemia, and 4/18 presented thrombocytopenia. The analysis of the liver, spleen, and bone data presented some limitations, but the available information suggests that patients did not deteriorate. GD patients who initiated ERT after July 2003 (n = 5) received lower dosage of imiglucerase since the beginning of the treatment; most of them demonstrated clinical and laboratorial response. From baseline to month 36, the consumption of imiglucerase by the reference center showed a significant reduction, which represented savings of USD 3 million to the public health system. The model of care of GD patients suggested by the BMH guidelines appears to be cost-effective and could be an example for management of rare diseases in underdeveloped countries. Copyright © 2009 S.

On November 13th, 2015, terrorist bomb explosions and gunshots occurred in Paris, France, with 129 people immediately killed, and more than 300 being injured. This article describes the staff organization, surgical management, and patterns of injuries in casualties who were referred to the Teaching European Hospital Georges Pompidou. This study is a retrospective analysis of the pre-hospital response and the in-hospital response in our referral trauma center. Data for patient flow, resource use, patterns of injuries and outcomes were obtained by the review of electronic hospital records. Forty-one patients were referred to our center, and 22 requiring surgery were hospitalized for>24h. From November 14th at 0:41 A.M. to November 15th at 1:10 A.M., 23 surgical interventions were performed on 22 casualties. Gunshot injuries and/or shrapnel wounds were found in 45%, fractures in 45%, head trauma in 4.5%, and abdominal injuries in 14%. Soft-tissue and musculoskeletal injuries predominated in 77% of cases, peripheral nerve injury was identified in 30%. The mortality rate was 0% at last follow up. Rapid staff and logistical response, immediate access to operating rooms, and multidisciplinary surgical care delivery led to excellent short-term outcomes, with no in-hospital death and only one patient being still hospitalized 45days after the initial event.

The aim of this study was to address the lack of information concerning the air quality in the city of Uberlândia, Minas Gerais, Brazil. In this study, we conducted an unprecedented experiment involving the in situ biomonitoring of air genotoxicity in the city center during and after a public transportation strike using the Tradescantia micronucleus test. The frequency of micronuclei was significantly higher in the city center compared with the reference site (Mann-Whitney test, p < 0.05), with the highest MN levels being observed during public transport stoppage (Kruskal-Wallis, Dunn p < 0.01). In addition, the multiple linear regression analyses revealed that the low circulation of buses during public transport stoppage and the increase in the concentration of particulate matter from the increased flow of vehicles in the city center during the strike positively influenced the MN frequency. The climatic factors did not change during the biomonitoring period, reflecting the fact that climatic factors did not influence the MN frequency.

1994-01-01

Since 1986, NASA's Commercial Remote Sensing Program (CRSP) at Stennis Space Center has supported commercial remote sensing partnerships with industry. CRSP's mission is to maximize U.S. market exploitation of remote sensing and related space-based technologies and to develop advanced technical solutions for spatial information requirements. Observation, geolocation, and communications technologies are converging and their integration is critical to realize the economic potential for spatial informational needs. Global positioning system (GPS) technology enables a virtual revolution in geopositionally accurate remote sensing of the earth. A majority of states are creating GPS-based reference networks, or high accuracy reference networks (HARN). A HARN can be defined for a variety of local applications and tied to aerial or satellite observations to provide an important contribution to geographic information systems (GIS). This paper details CRSP's experience in the design and implementation of a HARN in Mississippi and the design and support of future applications of integrated earth observations, geolocation, and communications technology.

My personal experiences at the BEST Medical Center: A day in the clinic-the morning.

Cohen, Philip R; Kurzrock, Razelle

2016-01-01

Dr. Ida Lystic is a gastroenterologist who trained at the OTHER (Owen T. Henry and Eugene Rutherford) Medical Center, after having completed her MD degree at the prestigious Harvey Medical School (recently renamed the Harvey Provider School). She accepted a faculty position at the BEST (Byron Edwards and Samuel Thompson) Medical Center. Dr. Lystic shares her experiences on a typical morning in gastroenterology clinic. Although her clinic start date was delayed by 2 months after becoming sick following a mandatory flu shot and having to complete more than 70 hours of compliance training modules, she is now familiar with the BEST system. Clinic scheduling priorities include ensuring that the staff can eat lunch together and depart at 5:00 pm. It is a continual challenge to find time to complete the electronic medical record after BEST changed from the SIMPLE (Succinct Input Making Patients Lives Electronic) system to LEGEND (referred to as Lengthy and Excessively Graded Evaluation and Nomenclature for Diagnosis by her colleagues). To maintain clinic punctuality, a compliance spreadsheet is e-mailed monthly to the Wait Time Committee. Their most recent corrective action plan for tardy physicians included placing egg timers on the doors and having nurses interrupt visits that exceed the allotted time. Administrative decisions have resulted in downsizing personnel. Patients are required to schedule their own tests and procedures and follow-up appointments-causing low patient satisfaction scores; however, the money saved lead to a large year-end bonus for the vice president of BEST Efficiency, who holds "providers" accountable for the poor patient experience. Although Dr. Ida Lystic and the gastroenterology clinic at "the BEST Medical Center" are creations of the authors' imagination, the majority of the anecdotes are based on actual events.

Objective: To observe interdepartmental variation in the availability of resources and academic activities within the various neurosurgery programs of Pakistan. Methods: This was a proforma-based survey of neurosurgery trainees and young neurosurgeons of Pakistan, looking at the academic infrastructure and output of their programs. The proforma was filled by 36 respondents from 11 neurosurgery centers of the country. All these centers were accredited for neurosurgery training in Pakistan. Results: Out of the 36 respondents, 30 were completing a Fellowship training (FCPS) and six were enrolled for a Master in Surgery (MS) program. About 80% of the participants used the Youman's Textbook of Neurosurgery as a reference book. Only 40% of the candidates had access to more than one indexed neurosurgery journal. Structured academic sessions (e.g., journal clubs and neuropathology meetings) were lacking in a majority of the training institutes, 95% of the trainees had no microsurgical laboratory experience, and modern neurosurgical tools (frameless neuronavigation system, neuroendoscopy) were in use at a few centers only. Conclusion: Neurosurgery training in Pakistan is not uniform and wide variations exist between the programs at the centers evaluated. We recommend exchange programs between centers at national and international levels, to allow trainees to gain first-hand exposure to training components not available in their own center.

The Lunar Ultraviolet Telescope Experiment (LUTE) is a 1-meter telescope for imaging from the lunar surface the ultraviolet spectrum between 1,000 and 3,500 angstroms. There have been several endorsements of the scientific value of a LUTE. In addition to the scientific value of LUTE, its educational value and the information it can provide on the design of operating hardware for long-term exposure in the lunar environment are important considerations. This report provides the results of the LUTE phase A activity begun at the George C. Marshall Space Flight Center in early 1992. It describes the objective of LUTE (science, engineering, and education), a feasible reference design concept that has evolved, and the subsystem trades that were accomplished during the phase A.

Lung Cancer Screening With Low-Dose CT: Implementation Amid Changing Public Policy at One Health Care System.

PubMed

Begnaud, Abbie; Hall, Thomas; Allen, Tadashi

2016-01-01

Screening for lung cancer with low-dose CT has evolved rapidly in recent years since the National Lung Screening Trial (NLST) results. Subsequent professional and governmental organization guidelines have shaped policy and reimbursement for the service. Increasingly available guidance describes eligible patients and components necessary for a high-quality lung cancer screening program; however, practical instruction and implementation experience is not widely reported. We launched a lung cancer screening program in the face of reimbursement and guideline uncertainties at a large academic health center. We report our experience with implementation, including challenges and proposed solutions. Initially, we saw less referrals than expected for screening, and many patients referred for screening did not clearly meet eligibility guidelines. We educated primary care providers and implemented system tools to encourage referral of eligible patients. Moreover, in response to the Centers for Medicare & Medicaid Services (CMS) final coverage determination, we report our programmatic adaptation to meet these requirements. In addition to the components common to all quality programs, individual health delivery systems will face unique barriers related to patient population, available resources, and referral patterns.

Cadence Tracking and Disturbance Rejection in Functional Electrical Stimulation Cycling for Paraplegic Subjects: A Case Study.

Functional electrical stimulation cycling has been proposed as an assistive technology with numerous health and fitness benefits for people with spinal cord injury, such as improvement in cardiovascular function, increase in muscular mass, and reduction of bone mass loss. However, some limitations, for example, lack of optimal control strategies that would delay fatigue, may still prevent this technology from achieving its full potential. In this work, we performed experiments on a person with complete spinal cord injury using a stationary tadpole trike when both cadence tracking and disturbance rejection were evaluated. In addition, two sets of experiments were conducted 6 months apart and considering activation of different muscles. The results showed that reference tracking is achieved above the cadence of 25 rpm with mean absolute errors between 1.9 and 10% when only quadriceps are activated. The disturbance test revealed that interferences may drop the cadence but do not interrupt a continuous movement if the cadence does not drop below 25 rpm, again when only quadriceps are activated. When other muscle groups were added, strong spasticity caused larger errors on reference tracking, but not when a disturbance was applied. In addition, spasticity caused the last experiments to result in less smooth cycling. © 2017 International Center for Artificial Organs and Transplantation and Wiley Periodicals, Inc.

When combinatorial processing results in reconceptualization: toward a new approach of compositionality

PubMed Central

Schumacher, Petra B.

2013-01-01

Propositional content is often incomplete but comprehenders appear to adjust meaning and add unarticulated meaning constituents effortlessly. This happens at the propositional level (The baby drank the bottle) but also at the phrasal level (the wooden turtle). In two ERP experiments, combinatorial processing was investigated in container/content alternations and adjective-noun combination transforming an animate entity into a physical object. Experiment 1 revealed that container-for-content alternations (The baby drank the bottle) engendered a Late Positivity on the critical expression and on the subsequent segment, while content-for-container alternations (Chris put the beer on the table) did not exert extra costs. In Experiment 2, adjective-noun combinations (the wooden turtle) also evoked a Late Positivity on the critical noun. First, the Late Positivities are taken to reflect discourse updating demands resulting from reference shift from the original denotation to the contextually appropriate interpretation (e.g., the reconceptualization form animal to physical object). This shift is supported by the linguistic unavailability of the original meaning, exemplified by copredication tests. Second, the data reveal that meaning alternations differ qualitatively. Some alternations involve (cost-free) meaning selection, while others engender processing demands associated with reconceptualization. This dissociation thus calls for a new typology of metonymic shifts that centers around the status of the involved discourse referents. PMID:24098293

Reference or standard atmospheric models have long been used for design and mission planning of various aerospace systems. The NASA Marshall Space Flight Center Global Reference Atmospheric Model was developed in response to the need for a design reference atmosphere that provides complete global geographical variability and complete altitude coverage (surface to orbital altitudes), as well as complete seasonal and monthly variability of the thermodynamic variables and wind components. In addition to providing the geographical, height, and monthly variation of the mean atmospheric state, it includes the ability to simulate spatial and temporal perturbations.

Is the 2000 CDC growth reference appropriate for developing countries?

Roberfroid, Dominique; Lerude, Marie-Paule; Pérez-Cueto, Armando; Kolsteren, Patrick

2006-04-01

In 2000, the Centers for Disease Control and Prevention (CDC) produced a revised growth reference. This has already been used in different settings outside the USA. Using data obtained during a nutritional survey in Madagascar, we compare results produced by using both the 2000 CDC and the 1978 National Center for Health Statistics (NCHS)/World Health Organization (WHO) growth references. We show that changing the reference has an important impact on nutritional diagnosis. In particular, the prevalence of wasting is greatly increased. This could generate substantial operational and clinical difficulties. We recommend continued use of the 1978 NCHS/WHO reference until release of the new WHO multi-country growth charts.

Awareness of risks associated with radiation exposure to patients and medical staff has significantly increased. It has been reported before that the use of advanced three-dimensional electro-anatomical mapping (EAM) system significantly reduces fluoroscopy time, however this study aimed for zero or near zero fluoroscopy ablation to assess its feasibility and safety in ablation of atrial fibrillation (AF) and other tachyarrhythmias in a "real world" experience of a single tertiary care center. This was a single-center study where ablation procedures were attempted without fluoroscopy in 34 consecutive patients with different tachyarrhythmias under the support of EAM system. When transseptal puncture (TSP) was needed, it was attempted under the guidance of intracardiac echocardiography (ICE). Among 34 patients consecutively enrolled in this study, 28 (82.4%) patients were referred for radiofrequency ablation (RFA) of AF, 3 (8.8%) patients for ablation of right ventricular outflow tract (RVOT) ventricular extrasystole (VES), 1 (2.9%) patient for ablation of atrioventricular nodal reentry tachycardia (AVNRT), 2 (5.9%) patients for typical atrial flutter ablation. In 21 (62%) patients the entire procedure was carried out without the use of fluoroscopy. Among 28 AF patients, 15 (54%) patients underwent ablation without the use of fluoroscopy and among these 15 patients, 10 (67%) patients required TSP under ICE guidance while 5 (33%) patients the catheters were introduced to left atrium through a patent foramen ovale. In 13 AF patients, fluoroscopy was only required for double TSP. The total procedure time of AF ablation was 130 ± 50 min. All patients referred for atrial flutter, AVNRT, and VES of the RVOT ablation did not require any fluoroscopy. This study demonstrates the feasibility of zero or near zero fluoroscopy procedure including TSP with the support of EAM and ICE guidance in a "real world" experience of a single tertiary care center. When fluoroscopy was required, it was limited to TSP hence keeping the radiation dose very low. .

Cytogenetic records were examined from consecutive nononcology blood specimens from 2,821 patients referred for cytogenetic services to Vanderbilt University Medical Center, Nashville, Tenn, from January 1985 to December 1992. We grouped the records according to reasons for referral and diagnoses. The most common reasons for referral were history of multiple abortions/miscarriages (23.3%), possibility of chromosomal abnormality (18.8%), and possible presence of the fragile X syndrome (15.6%). Overall, 2,418 (85.7%) patients were found to have normal chromosomes, and 403 (14.3%) patients were diagnosed with a cytogenetic abnormality. For example, 20 (5.4%) of the 373 males referred for the fragile X syndrome, or 1.4% of all males (20 of 1,428) excluding those with ambiguous genitalia, were diagnosed with this syndrome while 8 (2.1%) of the 373 males had a chromosome abnormality other than the fragile X chromosome. In addition, 85 (70.2%) of 121 males referred for Down syndrome had this syndrome, and only 53 (40.8%) of 130 females referred for Down syndrome had this diagnosis. This study should assist physicians in middle Tennessee and surrounding areas by increasing their awareness of the types and frequencies of cytogenetic diseases and by providing figures for comparison with other regions of the country.

Discovery of a Frank-Kasper [sigma] Phase in Sphere-Forming Block Copolymer Melts

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

Lee, Sangwoo; Bluemle, Michael J.; Bates, Frank S.

Sphere-forming block copolymers are known to self-assemble into body-centered cubic crystals near the order-disorder transition temperature. Small-angle x-ray scattering and transmission electron microscopy experiments on diblock and tetrablock copolymer melts have revealed an equilibrium phase characterized by a large tetragonal unit cell containing 30 microphase-separated spheres. This structure, referred to as the sigma ({sigma}) phase by Frank and Kasper more than 50 years ago, nucleates and grows from the body-centered cubic phase similar to its occurrence in metal alloys and is a crystal approximant to dodecagonal quasicrystals. Formation of the {sigma} phase in undiluted linear block copolymers (and certain branchedmore » dendrimers) appears to be mediated by macromolecular packing frustration, an entropic contribution to the interparticle interactions that control the sphere-packing geometry.« less

Given the multifaceted nature of dementia care management, an interdisciplinary comprehensive clinical approach is necessary. We describe our one-year experience with outpatient based dementia care at the Montefiore-Einstein Center for the Aging Brain (CAB) involving an multispecialty team of geriatricians, neurologists, and neuropsychologists, supported by geriatric psychiatrists, physiatrists, and social services. The goals of the CAB is to maximize dementia outcomes, including regular monitoring of patient's health and cognition, education and support to patients, their families and caregivers; initiation of pharmacological and non-pharmacological treatments as appropriate, and the facilitation of access to clinical trials. The CAB follows a consultative model where patients referred to the center receive a comprehensive three step evaluation and management plan from Geriatric, Neuropsychology and Neurology specialists that is shared with patient, caregivers and primary care physicians. Of the 366 patients seen for cognitive complaints in our first year, 71% were women with a mean age of 74 years. Self-identified ethnicity of patients included Caucasian (26%), African-American (25%), Hispanic (18%) and multiracial (5%). Common final diagnoses assigned at the CAB included mild cognitive impairment syndromes (31%), Alzheimer's disease (20%), mixed dementia (11%), vascular dementia (9%), Frontotemporal dementia (4%) and dementia with Lewy bodies (4%). Our one-year progress report indicates that an interdisciplinary clinical dementia care model is feasible in the outpatient setting as well as highly accepted by patients, caregivers and referring physicians. © 2016, Copyright the Authors Journal compilation © 2016, The American Geriatrics Society.

Power imbalance and consumerism in the doctor-patient relationship: health care providers' experiences of patient encounters in a rural district in India.

PubMed

Fochsen, Grethe; Deshpande, Kirti; Thorson, Anna

2006-11-01

The aim of this study is to explore health care providers' experiences and perceptions of their encounters with male and female patients in a rural district in India with special reference to tuberculosis (TB) care. The authors conducted semistructured interviews with 22 health care providers, 17 men and 5 women, from the public and private health care sectors. Findings reveal that doctors adopted an authoritarian as well as a consumerist approach in the medical encounter, indicating that power imbalances in the doctor-patient relationship are negotiable and subject to change. Gender was identified as an influencing factor of the doctor's dominance. A patient-centered approach, acknowledging patients' own experiences and shared decision making, is called for and should be included in TB control activities. This seems to be especially important for female patients, whose voices were not heard in the medical encounter.

To assess whether pediatric trauma patients initially evaluated at referring institutions met Massachusetts statewide trauma field triage criteria for stabilization and immediate transfer to a Pediatric Trauma Center (PTC) without pre-transfer CT imaging. A 3-year retrospective cohort study was completed at our level 1 PTC. Patients with CT imaging at referring institutions were classified according to a triage scheme based on Massachusetts statewide trauma field triage criteria. Demographic data and injury profile characteristics were abstracted from patient medical records and our pediatric trauma registry. A total of 262 patients with 413 CT scans were reviewed from 2008 to 2011. 172 patients scanned (66%, 95% CI: 60%, 71%) met criteria for immediate transfer to a pediatric trauma center. Notably, 110 scans (27% of the total performed at referring institutions) were duplicated within four hours upon arrival to our PTC. GCS score <14 (45%) was the most common requirement for transfer, and CT scan of the head was the most frequent scan obtained (53%). The majority of pediatric trauma patients were subjected to CT scans at referring institutions despite meeting Massachusetts trauma triage guidelines that call for stabilization and immediate transfer to a pediatric trauma center without any CT imaging. © 2014.

Anemia's adverse effects on physical and behavioral development and on the reduction of efficiency have been proven. The aim of this study was to determine the prevalence of anemia in pregnant women referred to the health care centers of Khorramabad from 2010 to 2014. In this cross-sectional study, 2821 prenatal care cases of pregnant women referred to health care centers of Khorramabad were studied. Studied variables included the following: hemoglobin, hematocrit, age, parity, trimester of pregnancy status, number of deliveries, number of abortions, number of children, weight, height, time gap from previous delivery, negative RH, history of eclampsia/preeclampsia, coagulation disorder and blood pressure. The mean age of the studied women was 26.7 ± 5.5. The mean levels of hemoglobin and hematocrit from the population was 12 ± 1.1 and 36.1 ± 9.2, respectively. The prevalence of anemia was 16.8%. Prevalence of anemia among pregnant women referred to health care centers of Khorramabad was found to be high. Staff working at different parts of health care centers were advised to pay more attention to this problem. They should also try to control and treat anemia by regular distribution of iron supplements among women referred to health care centers.

Integration of altitude and airspeed information into a primary flight display via moving-tape formats

1987-01-01

A ground-based aircraft simulation study was conducted to determine the effect on pilot performance of replacing the electromechanical altimeter and airspeed indicators with electronically generated representations integrated into the primary flight display via moving-tape (linear moving scale) formats. Several key factors relating to moving-tape formats were examined during the study: tape centering, secondary (trend) information, and tape orientation. The factor of centering refers to whether the tape was centered about the actual airspeed or altitude or about some defined reference value. Tape orientation refers to whether the values represented are arranged in either descending or ascending order. Six pilots participated in this study, with each subject performing 18 runs along a single, known flight profile. Subjective results indicated that the moving-tape formats were generally better than that of the conventional instruments. They also indicated that an actual-centered fixed pointer was preferred to a reference-centered pointer. Performance data for a visual secondary task showed that formats not containing trend information produced better performance; however, no difference was noted in airspeed tracking or altitude tracking performance. Regarding tape orientation, subjective comments indicated that there was lower work load and better performance when the airspeed tape had the high numbers at the top.

Leadership, collaboration, and effective training principles and practices from a decade of training by a center for public health preparedness.

To review a decade's experience of a Centers for Disease Control and Preparedness (CDC) funded Center for Public Health Preparedness (hereafter referred to as the Center) and to identify interventions that led to surmounting serious obstacles to achieving the Center's CDC-mandated goals and objectives. The Center's purpose was to train the public health workforce to protect the population from bioterrorism, infectious diseases, and emerging public health threats. This case study used the concepts of the judgment process as developed by Noel Tichy and Warren Bennis to describe the experiences and actions of the Center's leaders. Center staff used public health principles of collaboration, the use of relevant science, and professional training principles in developing and delivering training in epidemiology, behavioral health, crisis leadership, and other fields through distance learning and on-site methods. The study's primary focus was on training in Florida, although the program's reach was national and international. Preparedness training was provided to approximately 10,000 public health officials, primarily drawn from Florida. This is a descriptive study of the Center's activities. The interventions were the steps taken by Center leadership to accomplish the federal and state goals of the program, despite meeting major challenges. The outcome measures were degrees of success, as measured by federal and state officials and other indicators, in delivering high quality training that met CDC and state goals. The Center delivered trainings in fields determined to be needed in Florida and nationally. Participant and observer evaluations were strongly positive. Nationally published papers and presentations contributed to the training evidence base. The Florida Department of Health incorporated the trainings into Florida's mandatory training for Incident Command strike teams. The leaders of the Center and the Florida Department of Health developed a formal statement of principles to guide the training. These could be useful to other training organizations. The study illustrates the value of the Tichy and Bennis judgment process framework to describe actions of the Center leadership's successful effort to overcome system obstacles and provide high quality training to public health workers. The framework can be used by leaders in other organizations to increase their ability to make good judgments.

The German Aerospace Center (DLR) enabled German participation in the joint space campaign on the unmanned Shenzhou 8 spacecraft in November 2011. In this report, the effect of microgravity on Euglena gracilis cells is described. Custom-made dual compartment cell fixation units (containing cells in one chamber and fixative - RNA lysis buffer - in another one) were enclosed in a small container and placed in the Simbox incubator, which is an experiment support system. Cells were fixed by injecting them with fixative at different time intervals. In addition to stationary experiment slots, Simbox provides a 1 g reference centrifuge. Cell fixation units were mounted in microgravity and 1 g reference positions of Simbox. Two Simbox incubators were used, one for space flight and the other as ground reference. Cells were fixed soon after launch and shortly before return of the spaceship. Due to technical problems, only early in-flight samples (about 40 min after launch microgravity and corresponding 1 g reference) were fully mixed with fixative, therefore only data from those samples are presented. Transcription of several genes involved in signal transduction, oxidative stress defence, cell cycle regulation and heat shock responses was investigated with quantitative PCR. The data indicate that Euglena cells suffer stress upon short-term exposure to microgravity; various stress-induced genes were up-regulated. Of 32 tested genes, 18 were up-regulated, one down-regulated and the rest remained unaltered. These findings are in a good agreement with results from other research groups using other organisms. © 2013 German Botanical Society and The Royal Botanical Society of the Netherlands.

Center effect on ankle-brachial index measurement when using the reference method (Doppler and manometer): results from a large cohort study.

The ankle-brachial index (ABI) is a simple and noninvasive tool used to detect peripheral arterial disease (PAD). We aimed to assess, in a French multicenter cohort, the center effect associated with arterial pressure (AP) and ABI measurements using the reference method and using a semiautomatic device. This study included baseline and 9-year follow-up data from 3,664 volunteers of 10 health examination centers of the DESIR (Data from an Epidemiological Study on the Insulin Resistance) syndrome French cohort. Ankle and brachial AP were measured at inclusion by the reference method (a mercury sphygmomanometer coupled with a Doppler probe for ankle measurements) and at 9 years by a semiautomatic device (Omron HEM-705CP). The center effect was assessed by the intraclass correlation coefficient (ICC), ratio of the between-center variance to the total variance of the measurement. At inclusion, the sample mean age was 47.5 (s.d. 9.9) years; 49.3% were men. Although ICCs were smaller than 0.05 for brachial AP measurements, they were close to 0.18 and 0.20 for ankle systolic AP (SAP) and ABI measurements, respectively, when the reference method was used. No center effect for measures other than ankle SAP was detected. With the semiautomatic device method, all ICCs, including those for ankle SAP and ABI measurements, were between 0.005 and 0.04. We found an important center effect on ABI measured with a sphygmomanometer and a Doppler probe but not a semiautomatic device. A center effect should be taken into account when planning any multicenter study on ABI measurement.

Lead-Time Bias and Interhospital Transfer after Injury: Trauma Center Admission Vital Signs Underpredict Mortality in Transferred Trauma Patients.

Admission physiology predicts mortality after injury, but may be improved by resuscitation before transfer. This phenomenon, which has been termed lead-time bias, may lead to underprediction of mortality in transferred patients and inaccurate benchmarking in centers receiving large numbers of transfer patients. We sought to determine the impact of using vital signs on arrival at the referring center vs on arrival at the trauma center in mortality prediction models for transferred trauma patients. We performed a retrospective cohort study using a state-wide trauma registry including all patients age 16 years or older, with Abbreviated Injury Scale scores ≥ 3, admitted to level I and II trauma centers in Pennsylvania, from 2011 to 2014. The primary outcomes measure was the risk-adjusted association between mortality and interhospital transfer (IHT) when adjusting for physiology (as measured by Revised Trauma Score [RTS]) using the referring hospital arrival vital signs (model 1) compared with trauma center arrival vital signs (model 2). After adjusting for patient and injury factors, IHT was associated with reduced mortality (odds ratio [OR] 0.85; 95% CI 0.77 to 0.93) using the RTS from trauma center admission, but with increased mortality (OR 1.15; 95% CI 1.05 to 1.27) using RTS from the referring hospital. The greater the number of transfer patients seen by a center, the greater the difference in center-level mortality predicted by the 2 models (β -0.044; 95% CI -0.044 to -0.0043; p ≤ 0.001). Trauma center vital signs underestimate mortality in transfer patients and may lead to incorrect estimates of expected mortality. Where possible, benchmarking efforts should use referring hospital vital signs to risk-adjust IHT patients. Copyright © 2016 American College of Surgeons. Published by Elsevier Inc.

a Web-Based Framework for Visualizing Industrial Spatiotemporal Distribution Using Standard Deviational Ellipse and Shifting Routes of Gravity Centers

NASA Astrophysics Data System (ADS)

Song, Y.; Gui, Z.; Wu, H.; Wei, Y.

2017-09-01

Analysing spatiotemporal distribution patterns and its dynamics of different industries can help us learn the macro-level developing trends of those industries, and in turn provides references for industrial spatial planning. However, the analysis process is challenging task which requires an easy-to-understand information presentation mechanism and a powerful computational technology to support the visual analytics of big data on the fly. Due to this reason, this research proposes a web-based framework to enable such a visual analytics requirement. The framework uses standard deviational ellipse (SDE) and shifting route of gravity centers to show the spatial distribution and yearly developing trends of different enterprise types according to their industry categories. The calculation of gravity centers and ellipses is paralleled using Apache Spark to accelerate the processing. In the experiments, we use the enterprise registration dataset in Mainland China from year 1960 to 2015 that contains fine-grain location information (i.e., coordinates of each individual enterprise) to demonstrate the feasibility of this framework. The experiment result shows that the developed visual analytics method is helpful to understand the multi-level patterns and developing trends of different industries in China. Moreover, the proposed framework can be used to analyse any nature and social spatiotemporal point process with large data volume, such as crime and disease.

2016-05-01

Craniosynostosis has a relatively low incidence in the general population and its treatment requires cautious approaches. For these reasons, patients are usually referred to several specialists or a medical center. Therefore, most trainees and young surgeons do not have any chances to experience patients of craniosynostosis, but learn about it only from textbooks. And for a surgeon who tries to operate on a craniosynostosis patient, it is hard to make a proper preoperative plan.The authors suggest a polyurethane foam-filled skull replica of craniosynostosis for trainees that can also be used in planning a craniosynostosis operation.

International External Quality Assurance for Laboratory Diagnosis of Diphtheria ▿

The diphtheria surveillance network (DIPNET) encompassing National Diphtheria Reference Centers from 25 European countries is a Dedicated Surveillance Network recognized by the European Commission. A key DIPNET objective is the quality assessment of microbiological procedures for diphtheria across the European Union and beyond. A detailed questionnaire on the level of reference laboratory services and an external quality assessment (EQA) panel comprising six simulated throat specimens were sent to 34 centers. Twenty-three centers are designated National Diphtheria Reference Centers, with the laboratory in the United Kingdom being the only WHO Collaborating Centre. A variety of screening and identification tests were used, including the cysteinase test (20/34 centers), pyrazinamidase test (17/34 centers), and commercial kits (25/34 centers). The classic Elek test for toxigenicity testing is mostly used (28/34 centers), with variations in serum sources and antitoxin concentrations. Many laboratories reported problems obtaining Elek reagents or media. Only six centers produced acceptable results for all six specimens. Overall, 21% of identification and 13% of toxigenicity reports were unacceptable. Many centers could not isolate the target organism, and most found difficulties with the specimens that contained Corynebacterium striatum as a commensal contaminant. Nineteen centers generated either false-positive or negative toxigenic results, which may have caused inappropriate medical management. The discrepancies in this diphtheria diagnostics EQA alarmingly reflect the urgent need to improve laboratory performance in diphtheria diagnostics in Europe, standardize feasible and robust microbiological methods, and build awareness among public health authorities. Therefore, DIPNET recommends that regular workshops and EQA distributions for diphtheria diagnostics should be supported and maintained. PMID:19828749

To investigate interobserver variability in the delineation of head-and-neck (H&N) anatomic structures on CT images, including the effects of image artifacts and observer experience. Nine observers (7 radiation oncologists, 1 surgeon, and 1 physician assistant) with varying levels of H&N delineation experience independently contoured H&N gross tumor volumes and critical structures on radiation therapy treatment planning CT images alongside reference diagnostic CT images for 4 patients with oropharynx cancer. Image artifacts from dental fillings partially obstructed 3 images. Differences in the structure volumes, center-of-volume positions, and boundary positions (1 SD) were measured. In-house software created three-dimensional overlap distributions, including all observers. The effects of dental artifacts and observer experience on contouring precision were investigated, and the need for contrast media was assessed. In the absence of artifacts, all 9 participants achieved reasonable precision (1 SD < or =3 mm all boundaries). The structures obscured by dental image artifacts had larger variations when measured by the 3 metrics (1 SD = 8 mm cranial/caudal boundary). Experience improved the interobserver consistency of contouring for structures obscured by artifacts (1 SD = 2 mm cranial/caudal boundary). Interobserver contouring variability for anatomic H&N structures, specifically oropharyngeal gross tumor volumes and parotid glands, was acceptable in the absence of artifacts. Dental artifacts increased the contouring variability, but experienced participants achieved reasonable precision even with artifacts present. With a staging contrast CT image as a reference, delineation on a noncontrast treatment planning CT image can achieve acceptable precision.

Los Angeles County Elder Abuse Forensic Center cases involving adults aged 65 and older (April 2007-December 2009) were matched using one-to-one propensity-score matching to 33,650 usual care Adult Protective Services (APS) cases. The final analysis sample consisted of 472 FE cases. Compared to usual care, Forensic Center cases were more likely to be referred to the PG for investigation (30.6%, n = 72 vs. 5.9%, n = 14, p < .001). The strongest predictors of PG referral were suspected cognitive impairment, as identified by APS (odds ratio [OR] = 11.69, confidence intervals [CI]: 3.50-39.03), and Forensic Center review (OR = 7.85, CI: 3.86-15.95). Among referred cases, the court approved conservatorship at higher rates - though not statistically significant - for Forensic Center cases than usual care (52.9%, n = 36/68 vs. 41.7%, n = 5/12). Conservatorship may be a necessary last resort to improve safety for some FE victims, and the Forensic Center appears to provide a pathway to this service. These findings suggest modification to the Elder Abuse Forensic Center conceptual model and contribute to an emerging body of evidence on the role of the Forensic Center in addressing elder abuse.

Effects of visual information regarding allocentric processing in haptic parallelity matching.

Research has revealed that haptic perception of parallelity deviates from physical reality. Large and systematic deviations have been found in haptic parallelity matching most likely due to the influence of the hand-centered egocentric reference frame. Providing information that increases the influence of allocentric processing has been shown to improve performance on haptic matching. In this study allocentric processing was stimulated by providing informative vision in haptic matching tasks that were performed using hand- and arm-centered reference frames. Twenty blindfolded participants (ten men, ten women) explored the orientation of a reference bar with the non-dominant hand and subsequently matched (task HP) or mirrored (task HM) its orientation on a test bar with the dominant hand. Visual information was provided by means of informative vision with participants having full view of the test bar, while the reference bar was blocked from their view (task VHP). To decrease the egocentric bias of the hands, participants also performed a visual haptic parallelity drawing task (task VHPD) using an arm-centered reference frame, by drawing the orientation of the reference bar. In all tasks, the distance between and orientation of the bars were manipulated. A significant effect of task was found; performance improved from task HP, to VHP to VHPD, and HM. Significant effects of distance were found in the first three tasks, whereas orientation and gender effects were only significant in tasks HP and VHP. The results showed that stimulating allocentric processing by means of informative vision and reducing the egocentric bias by using an arm-centered reference frame led to most accurate performance on parallelity matching. © 2013 Elsevier B.V.

Effect of defuzzification method of fuzzy modeling

1994-10-01

Imprecision can arise in fuzzy relational modeling as a result of fuzzification, inference and defuzzification. These three sources of imprecision are difficult to separate. We have determined through numerical studies that an important source of imprecision is the defuzzification stage. This imprecision adversely affects the quality of the model output. The most widely used defuzzification algorithm is known by the name of `center of area' (COA) or `center of gravity' (COG). In this paper, we show that this algorithm not only maps the near limit values of the variables improperly but also introduces errors for middle domain values of the same variables. Furthermore, the behavior of this algorithm is a function of the shape of the reference sets. We compare the COA method to the weighted average of cluster centers (WACC) procedure in which the transformation is carried out based on the values of the cluster centers belonging to each of the reference membership functions instead of using the functions themselves. We show that this procedure is more effective and computationally much faster than the COA. The method is tested for a family of reference sets satisfying certain constraints, that is, for any support value the sum of reference membership function values equals one and the peak values of the two marginal membership functions project to the boundaries of the universe of discourse. For all the member sets of this family of reference sets the defuzzification errors do not get bigger as the linguistic variables tend to their extreme values. In addition, the more reference sets that are defined for a certain linguistic variable, the less the average defuzzification error becomes. In case of triangle shaped reference sets there is no defuzzification error at all. Finally, an alternative solution is provided that improves the performance of the COA method.

ABSTRACT Objective To compare the estimated cost of treatment of spinal disorders to those of this treatment in a specialized center. Methods An evaluation of average treatment costs of 399 patients referred by a Health Insurance Company for evaluation and treatment at the Spine Treatment Reference Center of Hospital Israelita Albert Einstein. All patients presented with an indication for surgical treatment before being referred for assessment. Of the total number of patients referred, only 54 underwent surgical treatment and 112 received a conservative treatment with motor physical therapy and acupuncture. The costs of both treatments were calculated based on a previously agreed table of values for reimbursement for each phase of treatment. Results Patients treated non-surgically had an average treatment cost of US$ 1,650.00, while patients treated surgically had an average cost of US$ 18,520.00. The total estimated cost of the cohort of patients treated was US$ 1,184,810.00, which represents a 158.5% decrease relative to the total cost projected for these same patients if the initial type of treatment indicated were performed. Conclusion Treatment carried out within a center specialized in treating spine pathologies has global costs lower than those regularly observed. PMID:23579752

New developments in the rapid diagnosis and treatment of boys with Duchenne muscular dystrophy (DMD) have led to growing enthusiasm for instituting DMD newborn screening (NBS) in the United States. Our group has been interested in developing clinical guidance to be implemented consistently in specialty care clinics charged with the care of presymptomatically identified newborns referred after DMD-NBS. We reviewed the existing literature covering patient-centered clinical follow-up after NBS, educational material from public health and advocacy sites, and federal recommendations on effective NBS follow-up. We discussed the review as a group and added our own experience to develop materials suitable for initial parent and primary care provider education. These materials and a series of templates for subspecialist encounters could be used to provide consistent care across centers and serve as the basis for ongoing quality improvement. PMID:27170260

Dynamic Jahn-Teller effect: Calculation of fine structure spectrum, isotope shift and Zeeman behavior at deep center Ni2+ in CdS

NASA Astrophysics Data System (ADS)

Schoepp, Juergen

The internal transition of the deep center Ni2+ in II to IV semiconductor cadmium sulfide is examined with reference to crystal field theory. An algorithm was developed for calculation, in a basis fitted to trigonal symmetry, of fine structure operator matrix which is made of the sum of operators from spin trajectory coupling, trigonal field and electron phonon coupling. The dependence of energy level on the mass was calculated in order to examine the isotropy effect at Ni2+ transition. The mass dependence of phonon energy was estimated in an atomic cluster by using a valence force model from Keating for elastic energy. The Zeeman behavior of Ni2+ transition was examined for magnetic fields; the Zeeman operator was added to the fine structure operator and the resulting matrix was diagonalized. It is noticed that calculations are quantitatively and qualitatively in agreement with experiments.

The use of rural sites to train badly needed primary care providers requires access to sophisticated medical information not traditionally available outside of academic health centers. Medical reference librarians can play a key role in the development of primary care training sites in rural settings. Electronic information technologies, with proactive support from medical reference librarians, can provide current and detailed information without concern for distance from the health science center library. This paper discusses recent developments in technology, describes current challenges to the application of this technology in rural settings, and provides policy recommendations for medical reference librarians to enhance rural primary care training.

[The Continued Breastfeeding Experiences of Women Who Suffer From Breast Abscess].

2016-04-01

Up to 11% of women with mastitis develop a breast abscess, which obviously affects breastfeeding. Therefore, this is a potentially significant issue for women's health. Women with breast abscesses suffer from severe pain. Pain is the most significant factor causing the termination of breastfeeding. The experience of women with breast abscesses who continued to breastfeed may provide valuable insights/guidance to women who are currently in the same or similar situations. This study explores the continuous breastfeeding experience of women with breast abscesses. We collected qualitative data from 10 qualified female participants using 60-90 minute, in-depth interviews that were conducted between April 2012 and June 2012 in a central medical center. All interviews were recorded and transcribed verbatim. Content analysis was used to analyze and categorize the major themes. Results were generalized into the following seven themes: (1) experiencing uncomfortable breast pain; (2) feeling helpless to manage the abnormal breast symptoms; (3) relying on the concept of motherhood to support continued breastfeeding; (4) feeling shocked about the process of diagnosis and treatment; (5) facing the doubts and difficulties regarding continuing to breastfeed; (6) experiencing the assistance of the support system for breastfeeding; (7) returning to a normal pattern of life. The findings provide nurses with a deeper understanding of the biological and psychological behaviors and social support system experiences of women with breast abscesses who continue to breastfeed. Study results may serve as a reference for nurses in providing mother-centered breastfeeding care.

Mental health issues among college students: who gets referred for psychopharmacology evaluation?

PubMed

Kirsch, Daniel J; Doerfler, Leonard A; Truong, Debbie

2015-01-01

To describe diagnostic and psychotropic medication prescription characteristics among college students referred by college counseling centers for psychopharmacologic evaluation. Participants were 540 college students referred by 6 college counseling centers in Massachusetts between November 2005 and May 2011. Students completed self-report measures of depression, anxiety, suicidal ideation and attempts, and substance use. Information regarding DSM-IV (Diagnostic and Statistical Manual of Mental Disorders, 4th edition) diagnosis, previous history of medication prescription, and current psychotropic medication(s) prescribed by the consulting psychiatrist was obtained from medical records. Depression, anxiety, and attention-deficit/hyperactivity disorder (ADHD) were the most common psychiatric problems identified in students. Half of these students had been prescribed mediation prior to evaluation. Antidepressant medication was the most frequently prescribed medication. A large proportion of students reported previous thoughts of suicide, and 12% had made at least 1 suicide attempt. Depression, anxiety, and ADHD are common among students referred by college counseling centers for medication evaluation and treatment.

Students' Learning Experiences from Didactic Teaching Sessions Including Patient Case Examples as Either Text or Video: A Qualitative Study.

Pedersen, Kamilla; Moeller, Martin Holdgaard; Paltved, Charlotte; Mors, Ole; Ringsted, Charlotte; Morcke, Anne Mette

2017-10-06

The aim of this study was to explore medical students' learning experiences from the didactic teaching formats using either text-based patient cases or video-based patient cases with similar content. The authors explored how the two different patient case formats influenced students' perceptions of psychiatric patients and students' reflections on meeting and communicating with psychiatric patients. The authors conducted group interviews with 30 medical students who volunteered to participate in interviews and applied inductive thematic content analysis to the transcribed interviews. Students taught with text-based patient cases emphasized excitement and drama towards the personal clinical narratives presented by the teachers during the course, but never referred to the patient cases. Authority and boundary setting were regarded as important in managing patients. Students taught with video-based patient cases, in contrast, often referred to the patient cases when highlighting new insights, including the importance of patient perspectives when communicating with patients. The format of patient cases included in teaching may have a substantial impact on students' patient-centeredness. Video-based patient cases are probably more effective than text-based patient cases in fostering patient-centered perspectives in medical students. Teachers sharing stories from their own clinical experiences stimulates both engagement and excitement, but may also provoke unintended stigma and influence an authoritative approach in medical students towards managing patients in clinical psychiatry.

The effects of in-service education to promote emergent literacy in child care centers: a feasibility study.

Girolametto, Luigi; Weitzman, Elaine; Lefebvre, Pascal; Greenberg, Janice

2007-01-01

The purpose of this study was to determine the feasibility of a 2-day in-service education program for (a) promoting the use of two emergent literacy strategies by early childhood educators and (b) increasing children's responses to these strategies. Sixteen early childhood educators were randomly assigned to an experimental and a control group. The experimental in-service program sought to increase educators' use of abstract utterances and print references. Educators were videotaped with small groups of preschoolers during storybook reading and a post-story craft activity. Pretest and posttest videotapes were coded to yield rates of abstract language, verbal print references, and children's responses. In comparison to the control group, educators in the experimental program used more abstract utterances that elicited talk about emotions and children's past experiences during storybook reading. They also used significantly more print references during a post-story craft activity. In addition, children in the experimental group responded more often with appropriate responses to abstract utterances and print references in comparison to children in the control group. A 2-day in-service education program resulted in short-term behavioral changes in educators' use of abstract language and print references. Suggestions for improving instruction include providing opportunities for classroom practice with feedback, modeling the use of strategies in classroom routines, and long-term mentoring of educators to promote retention of gains.

Controls Astrophysics and Structures Experiment in Space (CASES) advanced studies and planning

The CASES (Controls, Astrophysics, and Structures Experiment in Space) program consists of a flight demonstration of CSI (Controls-Structures Interactions) technology on the Space Shuttle. The basis structure consists of a 32 m deployable boom with actuators and sensors distributed along its length. Upon deployment from the Orbiter bay, the CASES structure will be characterized dynamically and its deformations controlled by a series of experimental control laws; and cold gas thrusters at its tip will be used to orient the Orbiter to a fixed celestial reference. The scientific observations will consist of hard x-ray imaging, at high resolution, of the Sun and the Galactic center. The hard x-ray observations require stable (few arc min) pointing at these targets for one or more position-sensitive proportional counters in the Orbiter bay, which view the object to be imaged through an aperture-encoding mask at the boom tip. This report gives the concensus developed at the second CASES Science Working Group meeting, which took place at NASA Marshall Space Flight Center May 16-17, 1990. An earlier paper and scientific summaries are available and form the basis for the present discussion.

Absolute IGS antenna phase center model igs08.atx: status and potential improvements

2016-04-01

On 17 April 2011, all analysis centers (ACs) of the International GNSS Service (IGS) adopted the reference frame realization IGS08 and the corresponding absolute antenna phase center model igs08.atx for their routine analyses. The latter consists of an updated set of receiver and satellite antenna phase center offsets and variations (PCOs and PCVs). An update of the model was necessary due to the difference of about 1 ppb in the terrestrial scale between two consecutive realizations of the International Terrestrial Reference Frame (ITRF2008 vs. ITRF2005), as that parameter is highly correlated with the GNSS satellite antenna PCO components in the radial direction.

The pairing center plays a key role in homolog paring: an explanation for adjacent-2 segregation in interchange heterozygotes.

PubMed

Luo, Peigao

2009-05-01

Having reflected on the discrepancy between various views of chromosome behavior during meiosis, we propose an alternative description of Mendel's first law of segregation by referring to the segregation of pairing centers instead of centromeres. We also propose an alternative description of Mendel's second law of independent assortment, which refers to the free combination of different pairing centers. This interpretation is based on the modified concept that true 'homologous chromosomes' should carry the pairing center rather than centromere: the length of homology or the importance of the homologous segment on the chromosome is the crucial factor in homologous chromosome pairing and synapsis.

Multiple reference frames in haptic spatial processing

NASA Astrophysics Data System (ADS)

Volčič, R.

2008-08-01

The present thesis focused on haptic spatial processing. In particular, our interest was directed to the perception of spatial relations with the main focus on the perception of orientation. To this end, we studied haptic perception in different tasks, either in isolation or in combination with vision. The parallelity task, where participants have to match the orientations of two spatially separated bars, was used in its two-dimensional and three-dimensional versions in Chapter 2 and Chapter 3, respectively. The influence of non-informative vision and visual interference on performance in the parallelity task was studied in Chapter 4. A different task, the mental rotation task, was introduced in a purely haptic study in Chapter 5 and in a visuo-haptic cross-modal study in Chapter 6. The interaction of multiple reference frames and their influence on haptic spatial processing were the common denominators of these studies. In this thesis we approached the problems of which reference frames play the major role in haptic spatial processing and how the relative roles of distinct reference frames change depending on the available information and the constraints imposed by different tasks. We found that the influence of a reference frame centered on the hand was the major cause of the deviations from veridicality observed in both the two-dimensional and three-dimensional studies. The results were described by a weighted average model, in which the hand-centered egocentric reference frame is supposed to have a biasing influence on the allocentric reference frame. Performance in haptic spatial processing has been shown to depend also on sources of information or processing that are not strictly connected to the task at hand. When non-informative vision was provided, a beneficial effect was observed in the haptic performance. This improvement was interpreted as a shift from the egocentric to the allocentric reference frame. Moreover, interfering visual information presented in the vicinity of the haptic stimuli parametrically modulated the magnitude of the deviations. The influence of the hand-centered reference frame was shown also in the haptic mental rotation task where participants were quicker in judging the parity of objects when these were aligned with respect to the hands than when they were physically aligned. Similarly, in the visuo-haptic cross-modal mental rotation task the parity judgments were influenced by the orientation of the exploring hand with respect to the viewing direction. This effect was shown to be modulated also by an intervening temporal delay that supposedly counteracts the influence of the hand-centered reference frame. We suggest that the hand-centered reference frame is embedded in a hierarchical structure of reference frames where some of these emerge depending on the demands and the circumstances of the surrounding environment and the needs of an active perceiver.

Reference set design for relational modeling of fuzzy systems

NASA Astrophysics Data System (ADS)

Lapohos, Tibor; Buchal, Ralph O.

1994-10-01

One of the keys to the successful relational modeling of fuzzy systems is the proper design of fuzzy reference sets. This has been discussed throughout the literature. In the frame of modeling a stochastic system, we analyze the problem numerically. First, we briefly describe the relational model and present the performance of the modeling in the most trivial case: the reference sets are triangle shaped. Next, we present a known fuzzy reference set generator algorithm (FRSGA) which is based on the fuzzy c-means (Fc-M) clustering algorithm. In the second section of this chapter we improve the previous FRSGA by adding a constraint to the Fc-M algorithm (modified Fc-M or MFc-M): two cluster centers are forced to coincide with the domain limits. This is needed to obtain properly shaped extreme linguistic reference values. We apply this algorithm to uniformly discretized domains of the variables involved. The fuzziness of the reference sets produced by both Fc-M and MFc-M is determined by a parameter, which in our experiments is modified iteratively. Each time, a new model is created and its performance analyzed. For certain algorithm parameter values both of these two algorithms have shortcomings. To eliminate the drawbacks of these two approaches, we develop a completely new generator algorithm for reference sets which we call Polyline. This algorithm and its performance are described in the last section. In all three cases, the modeling is performed for a variety of operators used in the inference engine and two defuzzification methods. Therefore our results depend neither on the system model order nor the experimental setup.

With proper logistical support and sponsorship, a laboratory in an industrialized nation might be able to act as a reference laboratory for clinicians based in a developing country. We built on previous experience in the clinical laboratory to see whether a specialized histopathology service (hematopathology) could be provided to a developing country without the expertise or experience to do it in country. Over an 13-year period, 582 cases from 579 individuals were analyzed. Principal pathologic findings included acute leukemia in 84 cases (14%), dyspoiesis in one or more of the hematopoietic lineages in 65 cases (11%, including three cases with high-grade myelodysplasia), 23 cases (4%) with findings suspicious for a chronic myeloproliferative disorder, 35 cases (6%) with findings suspicious for a lymphoproliferative disorder, and infectious organisms (presumably Leishmania in most instances) in 9 (1%) of cases. Specimens from 45 cases (8%) were unsatisfactory owing to extreme hemodilution and/or specimen degeneration. With proper support, a medical laboratory in an industrialized nation may serve as a reference facility for a developing nation. The use of existing infrastructure may be remarkably effective to achieve optimal turnaround time. Although the lack of ancillary studies and follow-up biopsies limit the ability to achieve a definitive diagnosis in many cases, this must be viewed in the context of the limited ability to diagnose or manage hematopoietic neoplasia in developing nations. © 2012 Blackwell Publishing Ltd.

Tracking Energy Flow Using a Volumetric Acoustic Intensity Imager (VAIM)

NASA Technical Reports Server (NTRS)

Klos, Jacob; Williams, Earl G.; Valdivia, Nicolas P.

2006-01-01

A new measurement device has been invented at the Naval Research Laboratory which images instantaneously the intensity vector throughout a three-dimensional volume nearly a meter on a side. The measurement device consists of a nearly transparent spherical array of 50 inexpensive microphones optimally positioned on an imaginary spherical surface of radius 0.2m. Front-end signal processing uses coherence analysis to produce multiple, phase-coherent holograms in the frequency domain each related to references located on suspect sound sources in an aircraft cabin. The analysis uses either SVD or Cholesky decomposition methods using ensemble averages of the cross-spectral density with the fixed references. The holograms are mathematically processed using spherical NAH (nearfield acoustical holography) to convert the measured pressure field into a vector intensity field in the volume of maximum radius 0.4 m centered on the sphere origin. The utility of this probe is evaluated in a detailed analysis of a recent in-flight experiment in cooperation with Boeing and NASA on NASA s Aries 757 aircraft. In this experiment the trim panels and insulation were removed over a section of the aircraft and the bare panels and windows were instrumented with accelerometers to use as references for the VAIM. Results show excellent success at locating and identifying the sources of interior noise in-flight in the frequency range of 0 to 1400 Hz. This work was supported by NASA and the Office of Naval Research.

We hypothesized that self-referred patients to academic centers will be equally distributed between general surgery and otolaryngology departments that perform thyroid surgery. We sought to quantify disparities in the assignment of these self-referred patients who may reach an institution through call centers or online pathways. Cross-sectional survey. Key words "thyroid surgery" and "thyroid cancer" were used along with the name of the Accreditation Council for Graduate Medical Education-listed otolaryngology program in both Google and Bing search engines. The top three search results for departments were reviewed, and a tally was given to general surgery (GS), otolaryngology-head and neck surgery (OLHNS), or neither. A multidisciplinary center with both GS and OLHNS was recorded as "equitable." Telephone calls were tallied if they were directed to GS or OLHNS. Out of 400 program tallies, 117 (29.25%) patients were directed to GS and 50 (12.5%) were directed to OLHNS. An additional 181 (45.25%) were directed to neither group ("neither") (P < .05). Fifty-two (13%) of the patients were referred to multidisciplinary groups ("equitable"). A telephone call survey had 62 patients (62%) assigned to a general surgeon, as opposed to 38 (38%) for OLHNS (P < .05). Five institutions offered a multidisciplinary group when searching with Bing, and 11 were found by searching with Google. There is not an equal distribution of self-referred patients with thyroid surgical pathology. It may be important to increase the online presence of OLHNS surgeons who perform thyroid surgery at academic medical institutions. Multidisciplinary centers focused on thyroid and parathyroid surgical disease represents one model of assigning self-referred patients.

Strengthening your ties to referring physicians through RIS/PACS integration.

Worthy, Susan; Rounds, Karla C; Soloway, Connie B

2003-01-01

Many imaging centers are turning to technology solutions to increase refering physician satisfaction, implementing such enhancements as automated report distribution, picture archiving and communications system (PACS), radiology information systems (RIS), and web-based results access. However, without seamless integration, these technology investments don't address the challenge at its core: convenient and reliable, two-way communication and interaction with referring physicians. In an integrated RIS/PACS solution, patient tracking in the RIS and PACS study status are logged and available to users. The time of the patient's registration at the imaging center, the exam start and completion time, the patient's departure time from the imaging center, and results status are all tracked and logged. An integrated RIS/PACS solution provides additional support to the radiologist, a critical factor that can improve the turnaround time of results to referring physicians. The RIS/PACS enhances the interpretation by providing the patient's history, which gives the radiologist additional insight and decreases the likelihood of missing a diagnostic element. In a tightly integrated RIS/PACS solution, results information is more complete. Physicians can view reports with associated images selected by the radiologist. They will also have full order information and complete imaging history including prior reports and images. Referring physicians can access and view images and exam notes at the same time that the radiologist is interpreting the exam. Without the benefit of an integrated RIS/PACS system, the referring physician would have to wait for the signed transcription to be released. In a seamlessly integrated solution, film-tracking modules within the RIS are fused with digital imaging workflow in the PACS. Users can see at a glance if a historical exam is available on film and benefit when a complete study history--both film-based and digital--is presented with the current case. It is up to the imaging center to market the benefits of reduced errors, reduced turnaround times, and a higher level of service to referring physician community, and encourage them to take advantage of the convenience it provides. The savvy imaging center will also regard the integrated RIS/PACS as a valuable marketing tool for use in attracting radiologists.

Bacterial reference genes for gene expression studies by RT-qPCR: survey and analysis.

Rocha, Danilo J P; Santos, Carolina S; Pacheco, Luis G C

2015-09-01

The appropriate choice of reference genes is essential for accurate normalization of gene expression data obtained by the method of reverse transcription quantitative real-time PCR (RT-qPCR). In 2009, a guideline called the Minimum Information for Publication of Quantitative Real-Time PCR Experiments (MIQE) highlighted the importance of the selection and validation of more than one suitable reference gene for obtaining reliable RT-qPCR results. Herein, we searched the recent literature in order to identify the bacterial reference genes that have been most commonly validated in gene expression studies by RT-qPCR (in the first 5 years following publication of the MIQE guidelines). Through a combination of different search parameters with the text mining tool MedlineRanker, we identified 145 unique bacterial genes that were recently tested as candidate reference genes. Of these, 45 genes were experimentally validated and, in most of the cases, their expression stabilities were verified using the software tools geNorm and NormFinder. It is noteworthy that only 10 of these reference genes had been validated in two or more of the studies evaluated. An enrichment analysis using Gene Ontology classifications demonstrated that genes belonging to the functional categories of DNA Replication (GO: 0006260) and Transcription (GO: 0006351) rendered a proportionally higher number of validated reference genes. Three genes in the former functional class were also among the top five most stable genes identified through an analysis of gene expression data obtained from the Pathosystems Resource Integration Center. These results may provide a guideline for the initial selection of candidate reference genes for RT-qPCR studies in several different bacterial species.

A reference radiosonde system for climate and weather research: IHOP experience

Global radiosonde data are required by meteorological analysis centers for initializing numerical prediction models for weather forecasting, and represent an increasingly valuable resource for studies of climate change and in the development, calibration and validation of retrieval techniques for atmospheric temperature and water vapor profiles from satellite. Unfortunately, the usefulness of radiosonde data is limited by sensor accuracy, by data reporting practices, and by the fact that sonde and sensor types vary by location and with time. Numerous studies and reports have called for a reference sonde to serve as a transfer standard to compare and connect data from past, present and future sonde systems. We are working on developing a reference radiosonde system at the Atmospheric Technology Division (ATD) at NCAR. The reference radiosonde system will carry the best sensors, have a flexible infrastructure to host multiple and different user-provided sensors and will be recoverable to reduce costs. The first version of the reference radiosonde system was deployed in the Oklahoma panhandle and Dodge City, KS (NWS radiosonde site) during the International H2O Project (IHOP_2002). A total of sixteen reference sondes were launched during IHOP either with Vaisala RS80 or Sippican (VIZ) radiosondes. The humidity data from the reference humidity sensor (Snow White, SW) are compared with Vaisala and VIZ data. The comparisons show that (a) VIZ carbon hygristor fails to respond to humidity changes in the upper troposphere, (b) the carbon hygristor inside the reference sonde has slower response than that inside NWS VIZ sonde, (c) Vaisala RS80-H agrees with SW very well in the middle and lower troposphere, and (d) SW can detect cirrus clouds near the tropopause and possibly estimate their ice water content (IWC). The climate impacts of these results are also discussed.

To examine the association between the certification as bariatric surgery center and volume and patient outcome, data collected in the German Bariatric Surgery Registry were evaluated. All data were registered prospectively in cooperation with the Institute of Quality Assurance in Surgery at Otto-von-Guericke University Magdeburg. Data collection began in 2005 for all bariatric procedures in an online database. Participation in the quality assurance study is required for all certified bariatric surgery centers in Germany. Descriptive evaluation and matched pairs analysis were performed. Patients were matched via propensity score taking into account BMI, age, and incidence of comorbidities. During the period from 2005 to 2013, 3083 male and 10,639 female patients were operated on with the RYGB primary approach. In Centers of Competence (77.2 %) and non-accredited hospitals (76.3 %), the proportion of female patients was significantly lower than in Centers of Reference/Excellence (78.7 %; p = 0.002). The mean age in Centers of Reference/Excellence (41.2 years) was significantly lower than in Centers of Competence (43.2 years; p < 0.05). Propensity score analysis was performed to compare matched patients with regard to BMI, age, and incidence of comorbidities. The rate of general and surgical postoperative complications and mortality rate was significantly lower in certified Centers of Reference/Excellence compared to Centers of Competence with 29 and non-certified hospitals. There is evidence of improved patient outcome in certified bariatric surgery centers with higher volume. The study supports the concept of certification. There are different factors which can and cannot be preoperatively modified and influence the perioperative outcome.

This study aims at developing a set of appropriate performance evaluation indices mainly based on balanced scorecard (BSC) for extension education centers in universities by utilizing multiple criteria decision making (MCDM). Through literature reviews and experts who have real practical experiences in extension education, adequate performance evaluation indices have been selected and then utilizing the decision making trial and evaluation laboratory (DEMATEL) and analytic network process (ANP), respectively, further establishes the causality between the four BSC perspectives as well as the relative weights between evaluation indices. According to this previous result, an empirical analysis of the performance evaluation of extension education centers of three universities at Taoyuan County in Taiwan is illustrated by applying VlseKriterijumska Optimizacija I Kompromisno Resenje (VIKOR). From the analysis results, it indicates that "Learning and growth" is the significant influential factor and it would affect the other three perspectives. In addition, it is discovered that "Internal process" perspective as well as "Financial" perspective play important roles in the performance evaluation of extension education centers. The top three key performance indices are "After-sales service", "Turnover volume", and "Net income". The proposed evaluation model could be considered as a reference for extension education centers in universities to prioritize their improvements on the key performance indices after performing VIKOR analyses. 2010 Elsevier Ltd.

In the field of spatial data every day we have more and more information available, but we still have little or very little information about the quality of spatial data. We consider that the automation of the spatial data quality assessment is a true need for the geomatic sector, and that automation is possible by means of web processing services (WPS), and the application of specific assessment procedures. In this paper we propose and develop a WPS tier centered on the automation of the positional quality assessment. An experiment using the NSSDA positional accuracy method is presented. The experiment involves the uploading by the client of two datasets (reference and evaluation data). The processing is to determine homologous pairs of points (by distance) and calculate the value of positional accuracy under the NSSDA standard. The process generates a small report that is sent to the client. From our experiment, we reached some conclusions on the advantages and disadvantages of WPSs when applied to the automation of spatial data accuracy assessments.

The Advanced Communications Technology Satellite (ACTS) Project invested heavily in prototype Ka-band satellite ground terminals to conduct an experiments program with ACTS. The ACTS experiments program proposed to validate Ka-band satellite and ground-station technology, demonstrate future telecommunication services, demonstrate commercial viability and market acceptability of these new services, evaluate system networking and processing technology, and characterize Ka-band propagation effects, including development of techniques to mitigate signal fading. This paper will present a summary of the fixed ground terminals developed by the NASA Glenn Research Center and its industry partners, emphasizing the technology and performance of the terminals and the lessons learned throughout their 6-year operation, including the inclined orbit phase-of-operations. The fixed ground stations used for experiments by government, academic, and commercial entities used reflector-based offset-fed antenna systems with antennas ranging in size from 0.35 to 3.4 in. in diameter. Gateway earth stations included two systems referred to as the NASA Ground Station (NGS) and the Link Evaluation Terminal (LET).

The S-193 Skylab radar altimeter was operated in a round-the-world pass on Jan. 31, 1974. The main purpose of this experiment was to test and 'measure' the variation of the sea surface topography using the Goddard Space Flight Center (GSFC) geoid model as a reference. This model is based upon 430,000 satellite and 25,000 ground gravity observations. Variations of the sea surface on the order of -40 to +60 m were observed along this pass. The 'computed' and 'measured' sea surfaces have an rms agreement on the order of 7 m. This is quite satisfactory, considering that this was the first time the sea surface has been observed directly over a distance of nearly 35,000 km and compared to a computed model. The Skylab orbit for this global pass was computed using the Goddard Earth Model (GEM 6) and S-band radar tracking data, resulting in an orbital height uncertainty of better than 5 m over one orbital period.

Medium-range structural properties of vitreous germania obtained through first-principles analysis of vibrational spectra.

We analyze the principal vibrational spectra of vitreous GeO(2) and derive therefrom structural properties referring to length scales beyond the basic tetrahedral unit. We generate a model structure that yields a neutron structure factor in accord with experiment. The inelastic-neutron, the infrared, and the Raman spectra, calculated within a density-functional approach, also agree with respective experimental spectra. The accord for the Raman spectrum supports a Ge-O-Ge angle distribution centered at 135 degrees. The Raman feature X(2) is found to result from vibrations in three-membered rings, and therefore constitutes a distinctive characteristic of the medium-range structure.

Shear waves converted from compressional waves at mantle discontinuities near 410- and 660-km depth recorded by two broadband seismic experiments in Iceland reveal that the center of an area of anomalously thin mantle transition zone lies at least 100 km south of the upper-mantle low-velocity anomaly imaged tomographically beneath the hotspot. This offset is evidence for a tilted plume conduit in the upper mantle, the result of either northward flow of the Icelandic asthenosphere or southward flow of the upper part of the lower mantle in a no-net-rotation reference frame. ?? 2002 Elsevier Science B.V.

Although there are a number of education models used today that expose bachelor of nursing degree students to perioperative nursing, producing nursing graduates who have the education and experience needed to work in the demanding perioperative arena is a challenge for education facilities. The University of Colorado Health Sciences Center, Denver, has developed a perioperative education model that interfaces with one of the university's clinical sites, University Hospital, Denver, to achieve a winning balance between perioperative education and employment. The model provides nursing students with a realistic perspective of the OR and gives the employer an opportunity to thoroughly evaluate potential employees--beyond a resume and references.

Consumer satisfaction with healthcare is an important quality and outcome indicator. Satisfaction may be at the crux of survival for healthcare delivery systems because it creates the competitive edge in healthcare. To better understand patient satisfaction by examining consumer healthcare experiences and expectations, a study was conducted. An important concept identified in the data, MY CARE, refers to a constellation of quality healthcare features that were wished for by all participants and realized by only some of them. The features of MY CARE offer lessons for all healthcare leaders to use when making improvements in care delivery systems-improvements that could create a more patient-centered healthcare system and boost patient satisfaction.

Conducting Research on the International Space Station using the EXPRESS Rack Facilities. Sean W. Thompson and Robert E. Lake. NASA Marshall Space Flight Center, Huntsville, AL, USA. Eight "Expedite the Processing of Experiments to Space Station" (EXPRESS) Rack facilities are located within the International Space Station (ISS) laboratories to provide standard resources and interfaces for the simultaneous and independent operation of multiple experiments within each rack. Each EXPRESS Rack provides eight Middeck Locker Equivalent locations and two drawer locations for powered experiment equipment, also referred to as sub-rack payloads. Payload developers may provide their own structure to occupy the equivalent volume of one, two, or four lockers as a single unit. Resources provided for each location include power (28 Vdc, 0-500 W), command and data handling (Ethernet, RS-422, 5 Vdc discrete, +/- 5 Vdc analog), video (NTSC/RS 170A), and air cooling (0-200 W). Each rack also provides water cooling (500 W) for two locations, one vacuum exhaust interface, and one gaseous nitrogen interface. Standard interfacing cables and hoses are provided on-orbit. One laptop computer is provided with each rack to control the rack and to accommodate payload application software. Four of the racks are equipped with the Active Rack Isolation System to reduce vibration between the ISS and the rack. EXPRESS Racks are operated by the Payload Operations Integration Center at Marshall Space Flight Center and the sub-rack experiments are operated remotely by the investigating organization. Payload Integration Managers serve as a focal to assist organizations developing payloads for an EXPRESS Rack. NASA provides EXPRESS Rack simulator software for payload developers to checkout payload command and data handling at the development site before integrating the payload with the EXPRESS Functional Checkout Unit for an end-to-end test before flight. EXPRESS Racks began supporting investigations onboard ISS on April 24, 2001 and will continue through the life of the ISS.

Object-location binding across a saccade: A retinotopic Spatial Congruency Bias

2017-01-01

Despite frequent eye movements that rapidly shift the locations of objects on our retinas, our visual system creates a stable perception of the world. To do this, it must convert eye-centered (retinotopic) input to world-centered (spatiotopic) percepts. Moreover, for successful behavior we must also incorporate information about object features/identities during this updating – a fundamental challenge that remains to be understood. Here we adapted a recent behavioral paradigm, the “Spatial Congruency Bias”, to investigate object-location binding across an eye movement. In two initial baseline experiments, we showed that the Spatial Congruency Bias was present for both gabor and face stimuli in addition to the object stimuli used in the original paradigm. Then, across three main experiments, we found the bias was preserved across an eye movement, but only in retinotopic coordinates: Subjects were more likely to perceive two stimuli as having the same features/identity when they were presented in the same retinotopic location. Strikingly, there was no evidence of location binding in the more ecologically relevant spatiotopic (world-centered) coordinates; the reference frame did not update to spatiotopic even at longer post-saccade delays, nor did it transition to spatiotopic with more complex stimuli (gabors, shapes, and faces all showed a retinotopic Congruency Bias). Our results suggest that object-location binding may be tied to retinotopic coordinates, and that it may need to be re-established following each eye movement rather than being automatically updated to spatiotopic coordinates.

A real-time global positioning system (GPS) Kalman filter has been developed to support automated rendezvous with the International Space Station (ISS). The filter is integrated with existing Shuttle rendezvous software running on a 486 laptop computer under Windows. In this work, we present real-time and postflight results achieved with the filter on STS-69. The experiment used GPS data from an Osborne/Jet propulsion Laboratory TurboRouge receiver carried on the Wake Shield Facility (WSF) free flyer and a Rockwell Collins 3M receiver carried on the Orbiter. Real time filter results, processed onboard the Shuttle and replayed in near-time on the ground, are based on single vehicle mode operation and on 5 to 20 minute snapshots of telemetry provided by WSF for dual-vehicle mode operation. The Orbiter and WSF state vectors calculated using our filter compare favorably with precise reference orbits determined by the University of Texas Center for Space Research. The lessons learned from this experiment will be used in conjunction with future experiments to mitigate the technology risk posed by automated rendezvous and docking to the ISS.

Boron neutrino flux and the MSW solution of the solar neutrino problem

There are large uncertainties in the predictions of the boron neutrino flux from the Sun which cannot be considered as being of purely statistical origin. We treat the magnitude of this flux, {Phi}{sub B}, as a parameter to be found from experiment. The properties of the, MSW solution to the solar neutrino problem for different values of {Phi}{sub B} are studied. Present, data give the bounds: 0.38 < {Phi}{sub B}/{Phi}{sub B}{sup O} < 3.1 (2{sigma}), where {Phi}{sub B}{sup O} {identical_to} 5.7 {center_dot} 10{sup 6} cm{sup {minus}2}s{sup {minus}1} is the flux in the reference SSM. The variations of the flux inmore » this interval enlarge the allowed region of mixing angles: sin{sup 2} 2{theta} = 0.2 {divided_by} 2 {center_dot} 10{sup {minus}4} {divided_by} 2 {center_dot} 10{sup {minus}2} (small mixing solutions) and sin{sup 2} 2{theta} = 0.2 {divided_by} 0.85 (large mixing solution). If the value of the original boron neutrino flux is about that measured by Kamiokande, a consistent description of the data is achieved for sin{sup 2} 2{theta} {approximately} (0.8 {divided_by} 2) {center_dot} 10{sup {minus}3} (``very small mixing solution``). The solution is characterized by a strong suppression of the beryllium neutrino line, a weak distortion of the high energy part of the baron neutrino spectrum and a value of the double ratio (CC/NC){sup exp}/(CC/NC){sup SSM} at E > 5 MeV close to 1. We comment on the possibility to measure the neutrino parameters and the original boron neutrino flux in future experiments.« less

Understanding Immersivity: Image Generation and Transformation Processes in 3D Immersive Environments

PubMed Central

Kozhevnikov, Maria; Dhond, Rupali P.

2012-01-01

Most research on three-dimensional (3D) visual-spatial processing has been conducted using traditional non-immersive 2D displays. Here we investigated how individuals generate and transform mental images within 3D immersive (3DI) virtual environments, in which the viewers perceive themselves as being surrounded by a 3D world. In Experiment 1, we compared participants’ performance on the Shepard and Metzler (1971) mental rotation (MR) task across the following three types of visual presentation environments; traditional 2D non-immersive (2DNI), 3D non-immersive (3DNI – anaglyphic glasses), and 3DI (head mounted display with position and head orientation tracking). In Experiment 2, we examined how the use of different backgrounds affected MR processes within the 3DI environment. In Experiment 3, we compared electroencephalogram data recorded while participants were mentally rotating visual-spatial images presented in 3DI vs. 2DNI environments. Overall, the findings of the three experiments suggest that visual-spatial processing is different in immersive and non-immersive environments, and that immersive environments may require different image encoding and transformation strategies than the two other non-immersive environments. Specifically, in a non-immersive environment, participants may utilize a scene-based frame of reference and allocentric encoding whereas immersive environments may encourage the use of a viewer-centered frame of reference and egocentric encoding. These findings also suggest that MR performed in laboratory conditions using a traditional 2D computer screen may not reflect spatial processing as it would occur in the real world. PMID:22908003

Tobacco treatment is underused in primary care. We designed a Tobacco Care Management system to increase the delivery of treatment and reduce the burden on primary care providers (PCPs). A one-click functionality added to the electronic health record (EHR) allowed PCPs to refer smokers to a centralized tobacco treatment coordinator (TTC) who called smokers, provided brief counseling, connected them to ongoing treatment and gave feedback to PCPs. To study the system's feasibility and acceptability among PCPs, and its utilization by smokers. Using a mixed methods design, we documented system utilization quantitatively from February 1, 2010 to July 31, 2011, and conducted two focus groups with PCPs in June 2011. Thirty-six PCPs and 2,894 smokers from two community health centers in Massachusetts. Quantitative: One-click referral utilization by PCPs, proportion of smokers referred and connected to treatment. Qualitative: PCPs' reasons for use, barriers to use, and experiences with feedback. Twenty-nine PCPs (81 %) used the functionality more than once, generating 466 referrals for 15 % of known smokers seen during the study. The TTC reached 260 (56 %) of the referrals and connected 135 (29 %) to additional treatment. The director of one center sent PCPs monthly feedback about their utilization compared to peers. These PCPs referred a greater proportion of their known smokers (18 % vs. 9 %, p<0.0001) and reported that monthly feedback motivated referrals. PCPs attending focus groups (n=24) appreciated the system's simplicity, access to updated resources, and time-efficient way to address smoking, and wanted more feedback about cessation outcomes. They collectively supported the system's continuation. A novel EHR-based Tobacco Care Management system was adopted by PCPs, especially those receiving performance feedback, and connected one-third of referred smokers to treatment. The model has the potential to improve the delivery and outcomes of evidence-based tobacco treatment in primary care.

Integration of altitude and airspeed information into a primary flight display via moving-tape formats: Evaluation during random tracking task

NASA Technical Reports Server (NTRS)

Abbott, Terence S.; Nataupsky, Mark; Steinmetz, George G.

1987-01-01

A ground-based aircraft simulation study was conducted to determine the effects on pilot preference and performance of integrating airspeed and altitude information into an advanced electronic primary flight display via moving-tape (linear moving scale) formats. Several key issues relating to the implementation of moving-tape formats were examined in this study: tape centering, tape orientation, and trend information. The factor of centering refers to whether the tape was centered about the actual airspeed or altitude or about some other defined reference value. Tape orientation refers to whether the represented values are arranged in descending or ascending order. Two pilots participated in this study, with each performing 32 runs along seemingly random, previously unknown flight profiles. The data taken, analyzed, and presented consisted of path performance parameters, pilot-control inputs, and electrical brain response measurements.

This study aimed to describe the clinical spectrum of dengue in children and adolescents from a hyperendemic region who were admitted for hospitalization. A retrospective study was conducted on patients diagnosed with dengue infection upon admission to a reference center in Fortaleza, Brazil. Of the 84 patients included, 42 underwent confirmatory testing. The main symptoms were fever, abdominal pain and vomiting. The median level of serum aspartate aminotransferase was 143.5±128mg/dL. A peculiar clinical profile was evident among children and adolescents with dengue infection in a reference center in northeast Brazil, including gastrointestinal symptoms and liver involvement.

Automatic frame-centered object representation and integration revealed by iconic memory, visual priming, and backward masking.

PubMed

Lin, Zhicheng; He, Sheng

2012-10-25

Object identities ("what") and their spatial locations ("where") are processed in distinct pathways in the visual system, raising the question of how the what and where information is integrated. Because of object motions and eye movements, the retina-based representations are unstable, necessitating nonretinotopic representation and integration. A potential mechanism is to code and update objects according to their reference frames (i.e., frame-centered representation and integration). To isolate frame-centered processes, in a frame-to-frame apparent motion configuration, we (a) presented two preceding or trailing objects on the same frame, equidistant from the target on the other frame, to control for object-based (frame-based) effect and space-based effect, and (b) manipulated the target's relative location within its frame to probe frame-centered effect. We show that iconic memory, visual priming, and backward masking depend on objects' relative frame locations, orthogonal of the retinotopic coordinate. These findings not only reveal that iconic memory, visual priming, and backward masking can be nonretinotopic but also demonstrate that these processes are automatically constrained by contextual frames through a frame-centered mechanism. Thus, object representation is robustly and automatically coupled to its reference frame and continuously being updated through a frame-centered, location-specific mechanism. These findings lead to an object cabinet framework, in which objects ("files") within the reference frame ("cabinet") are orderly coded relative to the frame.

High precision optomechanical assembly using threads as mechanical reference

NASA Astrophysics Data System (ADS)

Lamontagne, Frédéric; Desnoyers, Nichola; Bergeron, Guy; Cantin, Mario

2016-09-01

A convenient method to assemble optomechanical components is to use threaded interface. For example, lenses are often secured inside barrels using threaded rings. In other cases, multiple optical sub-assemblies such as lens barrels can be threaded to each other. Threads have the advantage to provide a simple assembly method, to be easy to manufacture, and to offer a compact mechanical design. On the other hand, threads are not considered to provide accurate centering between parts because of the assembly clearance between the inner and outer threads. For that reason, threads are often used in conjunction with precision cylindrical surfaces to limit the radial clearance between the parts to be centered. Therefore, tight manufacturing tolerances are needed on these pilot diameters, which affect the cost of the optical assembly. This paper presents a new optomechanical approach that uses threads as mechanical reference. This innovative method relies on geometric principles to auto-center parts to each other with a very low centering error that is usually less than 5 μm. The method allows to auto-center an optical group in a main barrel, to perform an axial adjustment of an optical group inside a main barrel, and to perform stacking of multiple barrels. In conjunction with the lens auto-centering method that also used threads as a mechanical reference, this novel solution opens new possibilities to realize a variety of different high precision optomechanical assemblies at lower cost.

Recent studies have emphasized the importance of childhood memories of threatening experiences and submissiveness in a diversity of psychological disorders. The purpose of this work was to study their specific relationship with hallucination proneness and ideas of reference in healthy subjects. The ELES scale for measuring memory of adverse childhood experiences, the DES-II scale for measuring dissociation, the LSHS-R scale for measuring hallucination proneness, and the REF for ideas of reference were applied to a sample of 472 subjects. A positive association was found between childhood memories of adverse experiences and hallucination proneness and ideas of reference, on one hand, and dissociation on the other. A mediation analysis showed that dissociation was a mediator between the memory of adverse childhood experiences and hallucination proneness on one hand, and ideas of reference on the other. When the role of mediator of the types of dissociative experiences was studied, it was found that absorption and depersonalization mediated between adverse experiences and hallucination proneness. However, this mediating effect was not found between adverse experiences and ideas of reference. The relationship between these last two variables was direct. The results suggest that childhood memories of adverse experiences are a relevant factor in understanding hallucination proneness and ideas of reference. Similarly, dissociation is a specific mediator between adverse childhood experiences and hallucination proneness. © 2018 Scandinavian Psychological Associations and John Wiley & Sons Ltd.

Getting the Picture: Iconicity Does Not Affect Representation-Referent Confusion

Wimmer, Marina C.; Robinson, Elizabeth J.; Koenig, Laura; Corder, Emma

2014-01-01

Three experiments examined 3- to 5-year-olds' (N = 428) understanding of the relationship between pictorial iconicity (photograph, colored drawing, schematic drawing) and the real world referent. Experiments 1 and 2 explored pictorial iconicity in picture-referent confusion after the picture-object relationship has been established. Pictorial iconicity had no effect on referential confusion when the referent changed after the picture had been taken/drawn (Experiment 1) and when the referent and the picture were different from the outset (Experiment 2). Experiment 3 investigated whether children are sensitive to iconicity to begin with. Children deemed photographs from a choice of varying iconicity representations as best representations for object reference. Together, findings suggest that iconicity plays a role in establishing a picture-object relation per se but is irrelevant once children have accepted that a picture represents an object. The latter finding may reflect domain general representational abilities. PMID:25247708

From transitions to transformation - A study of pharmacists developing patient-centered communication skills.

PubMed

Luetsch, Karen; Burrows, Judith

2017-08-12

Pharmacists' communication with patients often focuses on technical aspects of advice giving, while limiting socio-emotional content. To develop pharmacists' patient-centered communication a learning and practice module integrating motivational interviewing (MI) was designed for an online postgraduate program, and its impact on their self-described practice evaluated. To investigate whether training in patient-centered communication changes pharmacists' perceptions of communicating with patients, and how any changes in their communication style influenced interactions and relationships with patients. A descriptive, qualitative study analyzing reflective journal entries detailing pharmacists' experiences of implementing patient-centered communication in practice was designed, evaluating reflections on initial patient interactions after training and 9-12 weeks later. Using the framework method of content and thematic analysis, an evaluation framework was devised that integrated communication, change and learning theories. Reflections were categorized within the framework as transitional (e.g. using good communication skills), transactional (e.g. using MI techniques, achieving reciprocity) or transformational (e.g. describing transformative learning, changing frames of reference in understanding of patient-centeredness). Differences between the first and last journal entries were evaluated and analyzed using descriptive statistics. Eighty-nine pharmacists provided two reflective journal entries for evaluation. Over 9-12 weeks, pharmacists described a change in their perspective of patient-centeredness, how they expanded the socio-emotional aspects of communication and succeeded in difficult conversations. When applying the thematic evaluation framework to initial journal entries, 38 (42%) of reflections fell within the transitional category, 51 (58%) were deemed transactional and none transformational. This changed to 10 (11%) transitional, 45 (51%) transactional and 34 (38%) transformational. Differences were observed between journal entries from pharmacists who studied completely online and those who also attended a workshop. Learning and practicing techniques of MI and person-focused communication changed many pharmacists' frames of reference in regards to patient-centeredness and their self-reported communication style with patients.

National Aeronautics and Space Administration Dryden Flight Research Center acquired a Gulfstream III (GIII) aircraft to serve as a testbed for aeronautics flight research experiments. The aircraft is referred to as SCRAT, which stands for SubsoniC Research Aircraft Testbed. The aircraft’s mission is to perform aeronautics research; more specifically raising the Technology Readiness Level (TRL) of advanced technologies through flight demonstrations and gathering high-quality research data suitable for verifying the technologies, and validating design and analysis tools. The SCRAT has the ability to conduct a range of flight research experiments throughout a transport class aircraft’s flight envelope. Experiments ranging from flight-testing of a new aircraft system or sensor to those requiring structural and aerodynamic modifications to the aircraft can be accomplished. The aircraft has been modified to include an instrumentation system and sensors necessary to conduct flight research experiments along with a telemetry capability. An instrumentation power distribution system was installed to accommodate the instrumentation system and future experiments. An engineering simulation of the SCRAT has been developed to aid in integrating research experiments. A series of baseline aircraft characterization flights has been flown that gathered flight data to aid in developing and integrating future research experiments. This paper describes the SCRAT’s research systems and capabilities

Experiments ranging from flight-testing of a new aircraft system or sensor to those requiring structural and aerodynamic modifications to the aircraft can be accomplished. The aircraft has been modified to include an instrumentation system and sensors necessary to conduct flight research experiments along with a telemetry capability. An instrumentation power distribution system was installed to accommodate the instrumentation system and future experiments. An engineering simulation of the SCRAT has been developed to aid in integrating research experiments. A series of baseline aircraft characterization flights has been flown that gathered flight data to aid in developing and integrating future research experiments. This paper describes the SCRAT's research systems and capabilities.

The aim of this study was to evaluate immunoglobulin M indirect-fluorescent antibody test (IgM IFAT) for the diagnosis of acute or chronic Toxoplasma infection in pregnancy. Pregnant women with suspected acute toxoplasmosis referred to the Tuscany Reference Center for Infectious Diseases in Pregnancy during the period 1998-2012 were retrospectively enrolled. All women were tested with a panel of serological tests, including enzyme-linked immunosorbent assay for IgG avidity and IgM IFAT. On the basis of anamnestic, clinical, and serological criteria, pregnant women were classified into three groups: recently infected (RI), latently infected (LI), and doubtful latently infected (DLI). Patients classified as DLI were excluded from the analysis. The association between IgM IFAT (positive or negative) and the diagnosis of infection (acute or chronic) was assessed. Positive predictive value and negative predictive value of the IgM IFAT were calculated. A total of 810 pregnant women were enrolled in the study: 302 in the RI group and 508 in the LI group. Fifty-two women classified as DLI were excluded. IgM IFAT was positive in 172 out of 302 (56.9%) pregnant women in the RI group and in 29 out of 508 (5.7%) in the LI group. The positive predictive value and negative predictive value of IgM IFAT in predicting RI was 85.6% and 78.6%, respectively. IgM IFAT has reasonable sensitivity and specificity in diagnosing recent infection and, mostly in case of borderline avidity test, could be considered as a further aid for an accurate diagnosis of acute toxoplasmosis in pregnancy. © 2016 Japan Society of Obstetrics and Gynecology.

Alpha-fetoprotein (AFP) has been widely used in clinical practice for decades. However, large-scale survey of serum reference interval for ARCHITECT AFP is still absent in Chinese population. This study aimed to measure serum AFP levels in healthy Chinese Han subjects, which is a sub-analysis of an ongoing prospective, cross-sectional, multi-center study (ClinicalTrials.gov Identifier: NCT03047603). This analysis included a total of 530 participants (41.43±12.14years of age on average, 48.49% males), enrolled from 5 regional centers. Serum AFP level was measured by ARCHITECT immunoassay. Statistical analysis was performed using SAS 9.4 and R software. AFP distribution did not show significant correlation with age or sex. The overall median and interquartile range of AFP was 2.87 (2.09, 3.83) ng/mL. AFP level did not show a trend of increasing with age. The new reference interval was 2.0-7.07ng/mL (LOQ- 97.5th percentiles). The reference interval for ARCHITECT AFP is updated with the data of adequate number of healthy Han adults. This new reference interval is more practical and applicable in Chinese adults. Copyright © 2017 The Canadian Society of Clinical Chemists. Published by Elsevier Inc. All rights reserved.

2010-12-01

The artificial lung is a technical device for providing life support; it will be put in use when the natural lungs are failing and are not able to maintain sufficient oxygenation of the body's organ systems. From the viewpoint of long-term development, the artificial lung should be permanently implanted in the body, so that it will substitute for the human pulmonary function partially or completely. In this paper, four artificial lung technologies were expounded with reference to the development and research process of artificial lung. They were extracorporeal membrane oxygenation, intravascular artificial lung, implantable artificial lung, and pumpless extracorporeal lung assist. In this paper were described the structure of the four kinds of artificial lung, the working principle, and their advantages, disadvantages and indications. The prospect of artificial lung was evaluated in the light of the data from the existing animal experiments and from the clinical experience of the centers.

The Distance Education has evolved with the available technology in each new decade. The evolution and spread of mobile technology from year 2000s enabled their migration to this new platform: The Mobile Learning. Making it possible for professionals and students can carry with multimedia tools with Internet access to learning tools or professional references. This new concept fits very well the needs of Health, in which students must absorb and put into practice large amounts of technical knowledge, and also professionals must stay constantly updated. Distance Education in Health has received prominence in Brazil. A country of a geographically dispersed group of professionals, and research & training centers concentrated in the capitals. Updating field teams is a difficult task, but the information has access to modern technologies, which contribute to the teachers who use them. This paper, through the methodology of literature review, presents technology experiments in health environments and their considerations.

The 236U(n ,γ ) reaction cross section has been measured for the incident neutron energy range from 10 eV to 800 keV by using the Detector for Advanced Neutron Capture Experiments (DANCE) γ -ray calorimeter at the Los Alamos Neutron Science Center. The cross section was determined with the ratio method, which is a technique that uses the 235U(n ,f ) reaction as a reference. The results of the experiment are reported in the resolved and unresolved resonance energy regions. Individual neutron resonance parameters were obtained below 1 keV incident energy by using the R -matrix code sammy. The cross section in the unresolved resonance region is determined with improved experimental uncertainty. It agrees with both ENDF/B-VII.1 and JEFF-3.2 nuclear data libraries. The results above 10 keV agree better with the JEFF-3.2 library.

To summarize international experiences in promoting use of generics and to extract essence for China's reference. This is a commentary of two systematic reviews about policies to promote use of generics and its implications to China. Price, reimbursement, and generic substitution policies in European countries, and approaches in low and middle income countries in promoting market competition, appropriate intellectual property right protection strategy, and necessary demand side incentives, are all meaningful for China to contain soaring pharmaceutical expenditures, and to maintain the achievements and outcomes of the national health system reform. Effective promotion of generics use must be practice based on the real situation. Tailor-made and comprehensive measures are needed to address both demand and supply sides barriers before achieving tangible cost containment effect without unexpected side effects. © 2013 Wiley Publishing Asia Pty Ltd and Chinese Cochrane Center, West China Hospital of Sichuan University.

To describe our experience with the multidisciplinary management of both thoracic/diaphragmatic endometriosis (TED), applying a broadened definition of the “thoracic endometriosis syndrome (TES)” to define cases. We present a retrospective series of consecutive patients affected by pathology-proven TED, treated at our institution, during a period of 7 years. Five women were included. Two cases were referred due to catamenial chest/shoulder pain, one due to recurrent catamenial pneumothorax, one due to new-onset diaphragmatic hernia. One patient had not thoracic symptoms, and diaphragmatic endometriosis was found during gynecologic laparoscopy for pelvic endometriosis. Endometriosis was histologically confirmed in all cases. After follow-up all patients remain asymptomatic. Broadened TES criteria could increase the incidence of TED and determine better knowledge of this condition. Multidisciplinary, minimally invasive surgery is effective and safe, but should be reserved to tertiary referral centers.

We present and discuss JTRF2014, the Terrestrial Reference Frame (TRF) the Jet Propulsion Laboratory constructed by combining space-geodetic inputs from very long baseline interferometry (VLBI), satellite laser ranging (SLR), Global Navigation Satellite Systems (GNSS), and Doppler orbitography and radiopositioning integrated by satellite submitted for the realization of ITRF2014. Determined through a Kalman filter and Rauch-Tung-Striebel smoother assimilating position observations, Earth orientation parameters, and local ties, JTRF2014 is a subsecular, time series-based TRF whose origin is at the quasi-instantaneous center of mass (CM) as sensed by SLR and whose scale is determined by the quasi-instantaneous VLBI and SLR scales. The dynamical evolution of the positions accounts for a secular motion term, annual, and semiannual periodic modes. Site-dependent variances based on the analysis of loading displacements induced by mass redistributions of terrestrial fluids have been used to control the extent of random walk adopted in the combination. With differences in the amplitude of the annual signal within the range 0.5-0.8 mm, JTRF2014-derived center of network-to-center of mass (CM-CN) is in remarkable agreement with the geocenter motion obtained via spectral inversion of GNSS, Gravity Recovery and Climate Experiment (GRACE) observations and modeled ocean bottom pressure from Estimating the Circulation and Climate of the Ocean (ECCO). Comparisons of JTRF2014 to ITRF2014 suggest high-level consistency with time derivatives of the Helmert transformation parameters connecting the two frames below 0.18 mm/yr and weighted root-mean-square differences of the polar motion (polar motion rate) in the order of 30 μas (17 μas/d).

GA²LEN, the Global Allergy and Asthma European Network, has recently launched a program for the development, interaction, and accreditation of centers of reference and excellence in special areas of allergy embedded in its overall quality management of allergy centers of excellence. The first area chosen is urticaria. Urticaria is a common and debilitating condition and can be a challenge for both patients and treating physicians, especially when chronic. Centers of reference and excellence in urticaria (UCAREs) can help to improve the management of hard-to-treat conditions such as urticaria. Here, we describe the aims, the requirements and deliverables, the application process, and the audit and accreditation protocol for GA²LEN UCAREs. The main aims of GA²LEN UCAREs are to provide excellence in urticaria management, to increase the knowledge of urticaria by research and education, and to promote the awareness of urticaria by advocacy activities. To become a certified GA²LEN UCARE, urticaria centers have to apply and fulfill 32 requirements, defined by specific deliverables that are assessed during an audit visit. The GA²LEN UCARE program will result in a strong network of urticaria specialists, promote urticaria research, and harmonize and improve urticaria management globally. © 2016 John Wiley & Sons A/S.

Among solid organ transplant recipients, influenza infection is commonly associated with higher morbidity and mortality than immunocompetent hosts. Therefore, in these subjects influenza vaccination is of paramount importance. The main objective of the study was to assess compliance to vaccination and analyze factors associated with influenza vaccination of solid organ transplant recipients admitted to the Sicilian solid organ transplant Reference Center IRCCS-ISMETT in Palermo during 2014-2015 influenza season. Thirty one (37.8%) out of 82 solid organ transplant recipients were vaccinated against influenza. The main reason for vaccination refusal was fear of adverse reaction (n = 16, 31.4%), impaired health status (n = 14, 27.4%) and low vaccine efficacy (n = 10, 19.6%). Vaccinated solid organ transplant recipients compare with unvaccinated had smaller hospital admissions for infectious respiratory diseases (9.7% Vs 23.5%) during surveillance period. On multivariate analysis the factors positively associated with influenza vaccination were the advice of Reference Center physicians (OR 53.4, p < 0.001) and to perform vaccine against pneumococcus (OR 7.0, p = 0.016). This study showed that Reference Center physicians play a key role on vaccine communication and recommendation for patients at risk and it underlines the effectiveness of influenza vaccination in solid organ transplant recipients. However, it remains that, although physician advice resulted a strong determinant for vaccination, influenza vaccination coverage in this subset of population remains still unsatisfactory.

Agrawal, Deepak

2012-01-01

There is poor penetration of trauma healthcare delivery in rural areas. On the other hand, mobile penetration in India is now averaging 80% with most families having access to mobile phone. The aim of this study was to assess the implementation and socioeconomic impact of a call center in providing healthcare delivery for patients with head and spinal injuries. This was a prospective observational study carried out over a 6-month period at a level I trauma Center in New Delhi, India. A nine-seater call center was outsourced to a private company and the hospital's electronic medical records were integrated with the call-center operations. The call center was given responsibility of maintaining appointments and scheduling clinics for the whole hospital as well as ensuring follow-up visits. Trained call-center staff handled simple patient queries and referred the rest via email to concerned doctors. A telephonic survey was done prior to the start of call-center operations and after 3 months to assess for user satisfaction. The initial cost of outsourcing the call center was Rs 1.6 lakhs (US$ 4000), with a recurring cost of Rs 80,000 (US$ 2000) per month. A total of 484 patients were admitted in the department of Neurosurgery during the study period. Of these, 63% (n=305) were from rural areas. Patients' overall experience for clinic visits improved markedly following implementation of call center. Patient satisfaction for follow-up visits increased from a mean of 32-96%. Ninety-five percent patients reported a significant decrease in waiting time in clinics 80.4% reporting improved doctor-patient interaction. A total of 52 visits could be postponed/cancelled for patients living in far flung areas resulting in major socioeconomic benefits to these families. As shown by our case study, call centers have the potential to revolutionize delivery of trauma healthcare to rural areas in an extremely cost-effective manner.

The Space Station Biological Research Project (SSBRP), which is the combined efforts of the Centrifuge Facility (CF) and the Gravitational Biology Facility (GBF), is responsible for the development of life sciences hardware to be used on the International Space Station to support cell, developmental, and plant biology research. The SSBRP Reference Experiment Book was developed to use as a tool for guiding this development effort. The reference experiments characterize the research interests of the international scientific community and serve to identify the hardware capabilities and support equipment needed to support such research. The reference experiments also serve as a tool for understanding the operational aspects of conducting research on board the Space Station. This material was generated by the science community by way of their responses to reference experiment solicitation packages sent to them by SSBRP scientists. The solicitation process was executed in two phases. The first phase was completed in February of 1992 and the second phase completed in November of 1995. Representing these phases, the document is subdivided into a Section 1 and a Section 2. The reference experiments contained in this document are only representative microgravity experiments. They are not intended to define actual flight experiments. Ground and flight experiments will be selected through the formal NASA Research Announcement (NRA) and Announcement of Opportunity (AO) experiment solicitation, review, and selection process.

Frames of reference in action plan recall: influence of hand and handedness.

Evidence suggests that people are more likely to recall features of previous plans and use them for subsequent movements, rather than generating action plans from scratch for each movement. The information used for plan recall during object manipulation tasks is stored in extrinsic (object-centered) rather than intrinsic (body-centered) coordinates. The present study examined whether action plan recall processes are influenced by manual asymmetries. Right-handed (Experiment 1) and left-handed (Experiment 2) participants grasped a plunger from a home position using either the dominant or the non-dominant hand and placed it at one of the three target positions located at varying heights (home-to-target moves). Subsequently, they stepped sideways down from a podium (step-down podium), onto a podium (step-up podium), or without any podium present (no podium), before returning the plunger to the home platform using the same hand (target-back-to-home moves). The data show that, regardless of hand and handedness, participants grasped the plunger at similar heights during the home-to-target and target-back-to-home moves, even if they had to adopt quite different arm postures to do so. Thus, these findings indicate that the information used for plan recall processes in sequential object manipulation tasks is stored in extrinsic coordinates and in an effector-independent manner.

Social rejection of drug use is greater than that directed at other psychiatric conditions, like depression and anxiety, which may lead to social exclusion of substance users and prevent them from seeking and receiving treatment. The objective of this study is to investigate the stigma and discrimination related to addiction in treatment centers in Mexico City. Data are from a broad mixed methods study. The present study is a qualitative analysis of 35 in-depth interviews of drug users, family members, and providers, using guidelines for the exploration of experiences of stigma and discrimination related to substance abuse. A thematic analysis was carried out using specialized software (Atlas.ti 6.2.23). The common practices of stigma and discrimination (e.g., judging, mockery, inappropriate comments, overprotection, and hostile looks), were identified in participant testimonies. The narratives provide evidence of varied conditions of social and gender inequality, as well as experience of violence and abuse, that refer to a structural context of discrimination surrounding addiction, and that constitute obstacles to treatment. The findings allow for a description of the stigmatization process surrounding addiction as a shared problem that requires the implementation of coordinated treatment strategies. They also suggest the need for more comprehensive policies of inclusion, based on human rights, which favor prevention and treatment.

2006-01-01

As originally proposed, the Space Technology-7 Disturbance Reduction System (DRS) project, managed out of the Jet Propulsion Laboratory, was designed to validate technologies required for future missions such as the Laser Interferometer Space Antenna (LISA). The two technologies to be demonstrated by DRS were Gravitational Reference Sensors (GRSs) and Colloidal MicroNewton Thrusters (CMNTs). Control algorithms being designed by the Dynamic Control System (DCS) team at the Goddard Space Flight Center would control the spacecraft so that it flew about a freely-floating GRS test mass, keeping it centered within its housing. For programmatic reasons, the GRSs were descoped from DRS. The primary goals of the new mission are to validate the performance of the CMNTs and to demonstrate precise spacecraft position control. DRS will fly as a part of the European Space Agency (ESA) LISA Pathfinder (LPF) spacecraft along with a similar ESA experiment, the LISA Technology Package (LTP). With no GRS, the DCS attitude and drag-free control systems make use of the sensor being developed by ESA as a part of the LTP. The control system is designed to maintain the spacecraft s position with respect to the test mass, to within 10 nm/the square root of Hz over the DRS science frequency band of 1 to 30 mHz.

Families, especially in Eastern and Muslim countries, routinely accept the responsibility of caring for cancer patients. This study describes the transition to the new role of caregiving from the perspective of family caregivers in Iran as part of the current trend of recognizing the experiences of family members of breast cancer patients from different cultural perspectives. A descriptive exploratory qualitative research approach was used to investigate the experiences of family caregivers of patients with breast cancer in the transition to caregiving. The subjects were 23 family caregivers of breast cancer patients referred to cancer centers at Isfahan University hospitals who were selected by purposive sampling. Data was gathered through in-depth interviews. Interview transcripts were analyzed using conventional content analysis with an inductive approach. Data analysis identified the following categories: grasping a new situation without preparation, perceived inefficiency, infinite absence, and abandoned in the role. Caregivers believed that they were not prepared for their new circumstances and did not have the necessary competence and capabilities to meet the challenges of caregiving. They experienced negative consequences resulting from the difficult responsibility of caregiving. Moreover, they believed that they received limited support from relatives, health-care providers, and the community. The transition to the new role of caregiving is affected by experiences specific to the conditions of the caretakers. When these conditions can be understood and identified, it is possible to provide detailed information for policymaking and planning for family-centered care.

2015-01-01

Background: Domestic violence against women is a public health problem with negative consequences, and it is an intractable and widespread problem. This type of violence affects the stability of the family. Aim: The aim of this study was to estimate the prevalence of any violence against women referring to health centers and explore the associated risk factors with violence in Ahvaz, Iran. Methods: A cross-sectional study was conducted on randomly chosen samples of 368 married women aged between 15-55 years in 2013. The samples were divided to two groups, with abused experience and without abused experience. The data were amassed by questionnaire form. Results: The prevalence of violence against women was found to be around 63.8%, among them 58.8% were emotional abuse. The majority of women (84%) had never gone to a counseling center. Findings show 47% of women were silent, 27% got in a fight, 7% screamed, 6% abused their children, and 5% threw things when occurred violence against them. Experience of violence in women correlated with the marriage age of woman, numbers of children, and difference of marriage age between couple, marriage age of men, employed women, uneducated women and the rate of drugs use in their husbands. Conclusions: Nurses and other health care providers can and should play a major role in empowering women living with violence and promote education, social policies and attitudes that proactively prevent violence.

Cryodebridement (CD) refers to the removal of obstructive material from the lumen of the tracheobronchial tree by freezing with a cryoprobe, which is usually inserted through a flexible bronchoscope. This method of achieving instant recanalization of airways has been established for over 20 years, but published experience comprises limited case series. This study describes a single large-volume referral center experience, including clinical outcomes and safety profile. Electronic medical records of 156 patients who underwent bronchoscopic CD between December 2007 and March 2012 as the primary method to relieve airway obstruction were reviewed retrospectively. The most frequent cause of airway obstruction was malignancy (n = 88), with non-small-cell lung cancer and metastatic renal cell carcinoma being the most common etiologies. The site of obstruction was localized to the central airways in 63 patients (40%) and the distal airways in 44 patients (28%), and it was diffuse in 49 patients (32%). Bronchoscopic airway patency was achieved in 95% of patients, with the highest success rates found in those with obstruction localized in the central airways. Improvement in symptoms occurred in 118 (82%) of 144 symptomatic patients. Serious complications were reported in 17 patients (11%) and included respiratory distress, severe bleeding, airway injury, and hemodynamic instability. All patients responded to treatment, and no intra- or postoperative deaths were reported. CD, when used alone or in combination with other endoscopic treatment modalities, appears to be safe and effective in treating endoluminal airway obstruction.

Fitts's law in a selective reaching task: the proximity-to-hand effect of action-centered attention revisited.

PubMed

Welsh, Timothy N; Zbinden, Michele

2009-01-01

The "proximity-to-hand" effect refers to the finding that distractors between the home position and the target cause more interference in a selective reaching movement than distractors farther from the home position. Based largely on the proximity-to-hand effect, Tipper, Lortie, and Baylis (1992) proposed that attention is distributed in an action-centered framework such that the interference caused by a specific stimulus depends on the action. The current experiments sought to determine if there is an attentional preference for stimuli closer to home or for stimuli that activate more efficiently executed actions regardless of the location. Results supported the latter hypothesis in that the greatest interference was observed when the distractor activated an action with a lower index of difficulty than the target, even though that distractor was farther from home than the target. These findings indicate that the action context mediates the influence that nontarget stimuli have on the processing of target responses.

The influence of oxygen on the thermophysical properties of zirconium is being investigated using MSL-EML (Material Science Laboratory - Electromagnetic Levitator) on ISS (International Space Station) in collaboration with NASA, ESA (European Space Agency), and DLR (German Aerospace Center). Zirconium samples with different oxygen concentrations will be put into multiple melt cycles, during which the density, viscosity, surface tension, heat capacity, and electric conductivity will be measured at various undercooled temperatures. The facility check-up of MSL-EML and the first set of melting experiments have been successfully performed in 2015. The first zirconium sample will be tested near the end of 2015. As part of ground support activities, the thermophysical properties of zirconium and ZrO were measured using a ground-based electrostatic levitator located at the NASA Marshall Space Flight Center. The influence of oxygen on the measured surface tension was evaluated. The results of this research will serve as reference data for those measured in ISS.

Behavioral neuroscience of psychological pain.

PubMed

Papini, Mauricio R; Fuchs, Perry N; Torres, Carmen

2015-01-01

Pain is a common word used to refer to a wide range of physical and mental states sharing hedonic aversive value. Three types of pain are distinguished in this article: Physical pain, an aversive state related to actual or potential injury and disease; social pain, an aversive emotion associated to social exclusion; and psychological pain, a negative emotion induced by incentive loss. This review centers on psychological pain as studied in nonhuman animals. After covering issues of terminology, the article briefly discusses the daily-life significance of psychological pain and then centers on a discussion of the results originating from two procedures involving incentive loss: successive negative contrast-the unexpected devaluation of a reward-and appetitive extinction-the unexpected omission of a reward. The evidence reviewed points to substantial commonalities, but also some differences and interactions between physical and psychological pains. This evidence is discussed in relation to behavioral, pharmacological, neurobiological, and genetic factors that contribute to the multidimensional experience of psychological pain.

Self-referred whole-body CT imaging: current implications for health care consumers.

PubMed

Illes, Judy; Fan, Ellen; Koenig, Barbara A; Raffin, Thomas A; Kann, Dylan; Atlas, Scott W

2003-08-01

To conduct an empirical analysis of self-referred whole-body computed tomography (CT) and develop a profile of the geographic and demographic distribution of centers, types of services and modalities, costs, and procedures for reporting results. An analysis was conducted of Web sites for imaging centers accepting self-referred patients identified by two widely used Internet search engines with large indexes. These Web sites were analyzed for geographic location, type of screening center, services, costs, and procedures for managing imaging results. Demographic data were extrapolated for analysis on the basis of center location. Descriptive statistics, such as frequencies, means, SDs, ranges, and CIs, were generated to describe the characteristics of the samples. Data were compared with national norms by using a distribution-free method for calculating a 95% CI (P <.05) for the median. Eighty-eight centers identified with the search methods were widely distributed across the United States, with a concentration on both coasts. Demographic analysis further situated them in areas of the country characterized by a population that consisted largely of European Americans (P <.05) and individuals of higher education (P <.05) and socioeconomic status (P <.05). Forty-seven centers offered whole-body screening; heart and lung examinations were most frequently offered. Procedures for reporting results were highly variable. The geographic distribution of the centers suggests target populations of educated health-conscious consumers who can assume high out-of-pocket costs. Guidelines developed from within the profession and further research are needed to ensure that benefits of these services outweigh risks to individuals and the health care system.

The development of a revised version of multi-center molecular Ornstein-Zernike equation

NASA Astrophysics Data System (ADS)

Kido, Kentaro; Yokogawa, Daisuke; Sato, Hirofumi

2012-04-01

Ornstein-Zernike (OZ)-type theory is a powerful tool to obtain 3-dimensional solvent distribution around solute molecule. Recently, we proposed multi-center molecular OZ method, which is suitable for parallel computing of 3D solvation structure. The distribution function in this method consists of two components, namely reference and residue parts. Several types of the function were examined as the reference part to investigate the numerical robustness of the method. As the benchmark, the method is applied to water, benzene in aqueous solution and single-walled carbon nanotube in chloroform solution. The results indicate that fully-parallelization is achieved by utilizing the newly proposed reference functions.

Effects of anchoring and adjustment in the evaluation of product pricing.

PubMed

Elaad, Eitan; Sayag, Neta; Ezer, Aliya

2010-08-01

Anchoring and adjustment comprise a heuristic that creates expectations. Two types of anchors were applied on participants' evaluation of products: the price reference of the product (maximum, minimum, or no price reference) and the context in which the products were evaluated (the prestige of the shopping center). Results showed that both factors anchored evaluations of products' value. Context effects were explained by the different expectations of visitors in prestigious (looking for quality) and less prestigious (seeking a bargain) centers.

Neutron Analysis - Skylab Student Experiment ED-76

NASA Technical Reports Server (NTRS)

1973-01-01

The rate of neutron flow is commonly referred to as a flux. The measurement of neutron fluxes in Skylab was the subject of a proposal by Terry Quist of San Antonio, Texas. This chart describes Quist's experiment, Neutron Analysis, Skylab student experiment ED-76. These measurements were considered important not only by NASA but also by the scientific community for four reasons. High energy neutrons can be harmful to human tissue if they are present in significant quantities. Fluxes of neutrons can damage film and other sensitive experimental equipment in a marner similar to those produced by x-rays or other radiation. Furthermore, neutron fluxes can be used as a calibration source for other space-oriented particle physics experiments. Finally, neutron fluxes can affect sensitive x-ray and gamma-ray astronomy observations. Quist's objectives were to measure the neutron fluxes present in Skylab and, with the assistance of NASA and other physicists, to attempt determination of their origin as well as their energy range or spectrum. This experiment had stimulated interest in further studies of neutron phenomena in space. In March 1972, NASA and the National Science Teachers Association selected 25 experiment proposals for flight on Skylab. Science advisors from the Marshall Space Flight Center aided and assisted the students in developing the proposals for flight on Skylab.

Mapping the zone of eye-height utility for seated and standing observers

NASA Technical Reports Server (NTRS)

Wraga, M.; Proffitt, D. R.; Kaiser, M. K. (Principal Investigator)

2000-01-01

In a series of experiments, we delimited a region within the vertical axis of space in which eye height (EH) information is used maximally to scale object heights, referred to as the "zone of eye height utility" (Wraga, 1999b Journal of Experimental Psychology, Human Perception and Performance 25 518-530). To test the lower limit of the zone, linear perspective (on the floor) was varied via introduction of a false perspective (FP) gradient while all sources of EH information except linear perspective were held constant. For seated (experiment 1a) observers, the FP gradient produced overestimations of height for rectangular objects up to 0.15 EH tall. This value was taken to be just outside the lower limit of the zone. This finding was replicated in a virtual environment, for both seated (experiment 1b) and standing (experiment 2) observers. For the upper limit of the zone, EH information itself was manipulated by lowering observers' center of projection in a virtual scene. Lowering the effective EH of standing (experiment 3) and seated (experiment 4) observers produced corresponding overestimations of height for objects up to about 2.5 EH. This zone of approximately 0.20-2.5 EH suggests that the human visual system weights size information differentially, depending on its efficacy.

Automatic frame-centered object representation and integration revealed by iconic memory, visual priming, and backward masking

PubMed Central

Lin, Zhicheng; He, Sheng

2012-01-01

Object identities (“what”) and their spatial locations (“where”) are processed in distinct pathways in the visual system, raising the question of how the what and where information is integrated. Because of object motions and eye movements, the retina-based representations are unstable, necessitating nonretinotopic representation and integration. A potential mechanism is to code and update objects according to their reference frames (i.e., frame-centered representation and integration). To isolate frame-centered processes, in a frame-to-frame apparent motion configuration, we (a) presented two preceding or trailing objects on the same frame, equidistant from the target on the other frame, to control for object-based (frame-based) effect and space-based effect, and (b) manipulated the target's relative location within its frame to probe frame-centered effect. We show that iconic memory, visual priming, and backward masking depend on objects' relative frame locations, orthogonal of the retinotopic coordinate. These findings not only reveal that iconic memory, visual priming, and backward masking can be nonretinotopic but also demonstrate that these processes are automatically constrained by contextual frames through a frame-centered mechanism. Thus, object representation is robustly and automatically coupled to its reference frame and continuously being updated through a frame-centered, location-specific mechanism. These findings lead to an object cabinet framework, in which objects (“files”) within the reference frame (“cabinet”) are orderly coded relative to the frame. PMID:23104817

In 1995, in agreement with the German Federal Ministry of Health, the Robert Koch Institute established a public health microbiology system consisting of national reference centers (NRCs) and consultant laboratories (CLs). The goal was to improve the efficiency of infection protection by advising the authorities on possible measures and to supplement infectious disease surveillance by monitoring selected pathogens that have high public health relevance. Currently, there are 19 NRCs and 40 CLs, each appointed for three years. In 2009, an additional system of national networks of NRCs and CLs was set up in order to enhance effectiveness and cooperation within the national reference laboratory system. The aim of these networks was to advance exchange in diagnostic methods and prevention concepts among reference laboratories and to develop geographic coverage of services. In the last two decades, the German public health laboratory reference system coped with all major infectious disease challenges. The European Union and the European Centre for Disease Prevention and Control (ECDC) are considering implementing a European public health microbiology reference laboratory system. The German reference laboratory system should be well prepared to participate actively in this upcoming endeavor. Copyright © 2015 Elsevier GmbH. All rights reserved.

To explore the experience of pregnancy among Iranian women with HIV, 12 HIV-infected pregnant women who referred to counseling center for behavioral diseases in Imam Khomeini Hospital were recruited through purposive sampling. Data were collected by face-to-face, semi-structured interview and were analyzed using conventional content analysis method. Four main themes emerged from the data: fear and hope, stigma and discrimination, marital life stability, and trust in God. Despite concerns about mother-to-child transmission of HIV, and uncertain life span, HIV-infected women tended to continue their pregnancy, and having children was viewed as a window of hope for them. © The Author(s) 2015.

Effectiveness of person- and family-centered care transition interventions: a systematic review protocol.

PubMed

Backman, Chantal; Chartrand, Julie; Dingwall, Orvie; Shea, Beverley

2017-08-08

Care transitions from the hospital to home are critical to the sustainability of our health care system. Ineffective care transitions can be caused by high incidences of post-discharge adverse events, by poor communication with patients, and/or by inadequate information transfer between providers from the hospital to home. Any one of these can lead to fragmented care, high readmission rates, increased visits to the emergency department, and ultimately poor patient outcomes. Despite the ongoing improvement efforts of health care organizations, the efficacy of person- and family-centered care transition interventions on the quality of care and on the patient experience are not known. The aim of this systematic review is to critically analyze the body of evidence regarding the effectiveness of person- and family-centered care transition interventions on the quality of care, and the experience of patients. We will conduct a systematic review using the Cochrane Handbook's guidelines and will adhere to a standardized reporting format: Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA). A comprehensive search strategy will be conducted in the following databases: MEDLINE, EMBASE, CINAHL, Cochrane Central Register of Controlled Trials, and the Cochrane Consumers and Communication Group. Following a two-step screening process, data including the full reference, objectives, target population, description of the intervention and control intervention, outcome measures, design, length of post-intervention follow-up period, and the study results will be extracted, synthesized, and reported. Risk of bias and quality of the studies will also be assessed. This systematic review will summarize and present the evidence base for person- and family-centered care transition interventions. This review will also inform further research and will lay the groundwork for more empirical studies on person- and family-centered care transitions. Specifically, the results of this systematic review may inform the development of measures to monitor safe and effective person- and family-centered transitions from the hospital to home. These results may also be important for policy makers, decision-makers, clinicians, and patients/families who are involved in navigating the health care system. PROSPERO CRD42017067990.

The Influence of the Tri-reference Points on Fairness and Satisfaction Perception

Zhao, Lei; Ye, Junhui; Wu, Xuexian; Hu, Fengpei

2018-01-01

We examined the influence of three reference points (minimum requirements [MR], the status quo [SQ], and goal [G]) proposed by the tri-reference point (TRP) theory on fairness and satisfaction perceptions of pay in three laboratory experiments. To test the effects, we manipulated these three reference points both implicitly (Experiment 1) and explicitly (Experiments 2 and 3). We also provided the information of the salary offered to a peer person that was lower than, equal to, or higher than the salary offer to the participant. As hypothesized, the results demonstrated the important role of these reference points in judging the fairness of and satisfaction with pay when they were explicitly set (an interaction between reference points and social comparison in Experiments 2 and 3, but not in Experiment 1). Participants altered their judgments when the salary was in different regions. When the salary was below MR, participants perceived very low fairness and satisfaction, even when the offer was equal to/exceeded others. When the salary was above G, participants perceived much higher fairness and satisfaction, even with disadvantageous inequality. Participants were more impacted when they were explicitly instructed of the reference points (Experiments 2 and 3) than when they were not (Experiment 1). Moreover, MR appeared to be the most important, followed by G. A Salary below MR was judged as very unacceptable, with very low fairness and satisfaction ratings. PMID:29515503

We explored the current practice with respect to the neuropsychological assessment of surgical epilepsy patients in European epilepsy centers, with the aim of harmonizing and establishing common standards. Twenty-six epilepsy centers and members of "E-PILEPSY" (a European pilot network of reference centers in refractory epilepsy and epilepsy surgery), were asked to report the status of neuropsychological assessment in adults and children via two different surveys. There was a consensus among these centers regarding the role of neuropsychology in the presurgical workup. Strong agreement was found on indications (localization, epileptic dysfunctions, adverse drugs effects, and postoperative monitoring) and the domains to be evaluated (memory, attention, executive functions, language, visuospatial skills, intelligence, depression, anxiety, and quality of life). Although 186 different tests are in use throughout these European centers, a core group of tests reflecting a moderate level of agreement could be discerned. Variability exists with regard to indications, protocols, and paradigms for the assessment of hemispheric language dominance. For the tests in use, little published evidence of clinical validity in epilepsy was provided. Participants in the survey reported a need for improvement concerning the validity of the tests, tools for the assessment of everyday functioning and accelerated forgetting, national norms, and test co-normalization. Based on the present survey, we documented a consensus regarding the indications and principles of neuropsychological testing. Despite the variety of tests in use, the survey indicated that there may be a core set of tests chosen based on experience, as well as on published evidence. By combining these findings with the results of an ongoing systematic literature review, we aim for a battery that can be recommended for the use across epilepsy surgical centers in Europe.

To understand the organization of and the working conditions in family health care support centers, as well as subjective experiences related to work in two of these centers. This was a case study carried out during 2011 and 2012 in two family health care support centers in Sao Paulo, Southeastern Brazil. Data were collected and analyzed using two theoretical-methodological references from ergonomics and work psychodynamics influenced, respectively, by ergonomic work analysis, developed based on open observations of a variety of tasks and on interviews and in practice in work psychodynamics, carried out using think tanks about the work. The work of the Family Health Care Support Centers in question is constituted on the bases of complex, diversified actions to be shared among the various professionals and teams involved. Innovative technological tools, which are not often adopted by primary health care professionals, are used and the parameters and productivity measures do not encompass the specificity and the complexity of the work performed. These situations require constant organizational rearrangement, especially between the Family Health Care Support Centers and the Family Health Care Teams, causing difficulties in carrying out the work as well as in constituting the identity of the professionals studied. The study attempts to lend greater visibility to the work processes at the Family Health Care Support Centers in order to contribute to advances in public policy on primary healthcare. It is important to stress that introducing changes at work, which affect both its organization and work conditions, is above all a commitment, which to be effective, must be permanent and must involve the different levels of hierarchy.

Radiation Pressure Forces, the Anomalous Acceleration, and Center of Mass Motion for the TOPEX/POSEIDON Spacecraft

NASA Technical Reports Server (NTRS)

Kubitschek, Daniel G.; Born, George H.

2000-01-01

Shortly after launch of the TOPEX/POSEIDON (T/P) spacecraft (s/c), the Precision Orbit Determination (POD) Team at NASA's Goddard Space Flight Center (GSFC) and the Center for Space Research at the University of Texas, discovered residual along-track accelerations, which were unexpected. Here, we describe the analysis of radiation pressure forces acting on the T/P s/c for the purpose of understanding and providing an explanation for the anomalous accelerations. The radiation forces acting on the T/P solar army, which experiences warping due to temperature gradients between the front and back surfaces, are analyzed and the resulting along-track accelerations are determined. Characteristics similar to those of the anomalous acceleration are seen. This analysis led to the development of a new radiation form model, which includes solar array warping and a solar array deployment deflection of as large as 2 deg. As a result of this new model estimates of the empirical along-track acceleration are reduced in magnitude when compared to the GSFC tuned macromodel and are less dependent upon beta(prime), the location of the Sun relative to the orbit plane. If these results we believed to reflect the actual orientation of the T/P solar array then motion of the solar array must influence the location of the s/c center of mass. Preliminary estimates indicate that the center of mass can vary by as much as 3 cm in the radial component of the s/c's position due to rotation of the deflected, warped solar array panel .The altimeter measurements rely upon accurate knowledge of the center of mass location relative to the s/c frame of reference. Any radial motion of the center of mass directly affects the altimeter measurements.

Clinical studies often use data dictionaries with controlled sets of terms to facilitate data collection, limited interoperability and sharing at a local site.

Clinical studies often use data dictionaries with controlled sets of terms to facilitate data collection, limited interoperability and sharing at a local site. Multi-center retrospective clinical studies require that these data dictionaries, originating from individual participating centers, be harmonized in preparation for the integration of the corresponding clinical research data. Domain ontologies are often used to facilitate multi-center data integration by modeling terms from data dictionaries in a logic-based language, but interoperability among domain ontologies (using automated techniques) is an unresolved issue.

Despite community health centers' substantial role in local communities and in the broader safety-net healthcare system, very limited research has been conducted on community health center research experience, infrastructure, or needs from a national perspective. A national survey of 386 community health centers was conducted in 2011 and 2012 to assess research engagement among community health centers and their perceived needs, barriers, challenges, and facilitators with respect to their involvement in public health and health services research. This paper analyzes the differences between health centers that currently conduct or participate in research and health centers that have no prior research experience to determine whether prior research experience is indicative of different perceived challenges and research needs in community health center settings. © 2014 Wiley Periodicals, Inc.

Reference Frames and 3-D Shape Perception of Pictured Objects: On Verticality and Viewpoint-From-Above

PubMed Central

van Doorn, Andrea J.; Wagemans, Johan

2016-01-01

Research on the influence of reference frames has generally focused on visual phenomena such as the oblique effect, the subjective visual vertical, the perceptual upright, and ambiguous figures. Another line of research concerns mental rotation studies in which participants had to discriminate between familiar or previously seen 2-D figures or pictures of 3-D objects and their rotated versions. In the present study, we disentangled the influence of the environmental and the viewer-centered reference frame, as classically done, by comparing the performances obtained in various picture and participant orientations. However, this time, the performance is the pictorial relief: the probed 3-D shape percept of the depicted object reconstructed from the local attitude settings of the participant. Comparisons between the pictorial reliefs based on different picture and participant orientations led to two major findings. First, in general, the pictorial reliefs were highly similar if the orientation of the depicted object was vertical with regard to the environmental or the viewer-centered reference frame. Second, a viewpoint-from-above interpretation could almost completely account for the shears occurring between the pictorial reliefs. More specifically, the shears could largely be considered as combinations of slants generated from the viewpoint-from-above, which was determined by the environmental as well as by the viewer-centered reference frame.

Objectives: To report the management of burn injuries that occured in the Syria civil war, which were referred to our burn center. Methods: Forty-three patients with burns, injured in the civil war in Syria and whom were referred to Dr. Lütfi Kırdar Kartal Educating and Training Hospital Burn Centre of İstanbul, Turkey between 2011-2015 were analyzed in a retrospective study. Results: Most of our patients were in major burn classification (93%; 40/43) and most of them had burns >15% total on body surface area. Most of them were admitted to our center late after first management at centers with improper conditions and in cultures of these patients unusual and resistant strains specific to the battlefield were produced. Conclusion: Immediate transfer of the patients from the scene of incidence to burn centers ensures early treatment, this factor may be effective on the outcome of these patients. PMID:28042637

Word learning in adults with second-language experience: effects of phonological and referent familiarity.

Kaushanskaya, Margarita; Yoo, Jeewon; Van Hecke, Stephanie

2013-04-01

The goal of this research was to examine whether phonological familiarity exerts different effects on novel word learning for familiar versus unfamiliar referents and whether successful word learning is associated with increased second-language experience. Eighty-one adult native English speakers with various levels of Spanish knowledge learned phonologically familiar novel words (constructed using English sounds) or phonologically unfamiliar novel words (constructed using non-English and non-Spanish sounds) in association with either familiar or unfamiliar referents. Retention was tested via a forced-choice recognition task. A median-split procedure identified high-ability and low-ability word learners in each condition, and the two groups were compared on measures of second-language experience. Findings suggest that the ability to accurately match newly learned novel names to their appropriate referents is facilitated by phonological familiarity only for familiar referents but not for unfamiliar referents. Moreover, more extensive second-language learning experience characterized superior learners primarily in one word-learning condition: in which phonologically unfamiliar novel words were paired with familiar referents. Together, these findings indicate that phonological familiarity facilitates novel word learning only for familiar referents and that experience with learning a second language may have a specific impact on novel vocabulary learning in adults.

Practitioner Perspectives on a Disaster Management Architecture

NASA Astrophysics Data System (ADS)

Moe, K.; Evans, J. D.

2012-12-01

The Committee on Earth Observing Satellites (CEOS) Working Group on Information Systems and Services (WGISS) is constructing a high-level reference model for the use of satellites, sensors, models, and associated data products from many different global data and service providers in disaster response and risk assessment. To help streamline broad, effective access to satellite information, the reference model provides structured, shared, holistic views of distributed systems and services - in effect, a common vocabulary describing the system-of-systems building blocks and how they are composed for disaster management. These views are being inferred from real-world experience, by documenting and analyzing how practitioners have gone about using or providing satellite data to manage real disaster events or to assess or mitigate hazard risks. Crucial findings and insights come from case studies of three kinds of experience: - Disaster response and recovery (such as the 2008 Sichuan/Wenchuan earthquake in China; and the 2011 Tohoku earthquake and tsunami in Japan); - Technology pilot projects (such as NASA's Flood Sensor Web pilot in Namibia, or the interagency Virtual Mission Operation Center); - Information brokers (such as the International Charter: Space and Major Disasters, or the U.K.-based Disaster Management Constellation). Each of these experiences sheds light on the scope and stakeholders of disaster management; the information requirements for various disaster types and phases; and the services needed for effective access to information by a variety of users. They also highlight needs and gaps in the supply of satellite information for disaster management. One need stands out: rapid and effective access to complex data from multiple sources, across inter-organizational boundaries. This is the near-real-time challenge writ large: gaining access to satellite data resources from multiple organizationally distant and geographically disperse sources, to meet an urgent need. The case studies and reference model will highlight gaps in data supply and data delivery technologies, and suggest recommended priorities for satellite missions, ground data systems, and third-party service providers.

Compared to other regions of the world, palliative care (PC) in the Eastern Mediterranean region is at an earlier stage of development. The Palliative Care Center of Kuwait (PCC-K) was established a few years ago as the first stand-alone PC center in the region. This study was conducted to investigate the timing of referral to the PCC-K and its outcome. Retrospective review of referrals to the PCC-K during its first 3 years of action. Late referral was defined as referral during the last 30 days of life. During the 3-year period, 498 patients with cancer were referred to the PCC-K of whom 467 were eligible for analysis. Referral was considered late in 58% of patients. Nononcology facilities were more likely to refer patients late when compared to oncology facilities ( P = .033). The palliative performance scale (PPS) was ≤30 in 59% of late referrals and 21% in earlier referrals ( P < .001). Among 467 referred patients, 342 (73%) were eligible for transfer to the PCC-K, 102 (22%) were ineligible, and 23 (5%) died before assessment by the PCC-K consultation team. From the 342 eligible patients, the family caregivers refused the transfer of 64 (19%) patients to the PCC-K. Patients are frequently referred late to the PCC-K. Further research to identify barriers to PC and its early integration in Kuwait is required. The PPS may be useful in identifying late referrals.

Comparing The Effects Of Reference Pricing And Centers-Of-Excellence Approaches To Value-Based Benefit Design.

PubMed

Zhang, Hui; Cowling, David W; Facer, Matthew

2017-12-01

Various health insurance benefit designs based on value-based purchasing have been promoted to steer patients to high-value providers, but little is known about the designs' relative effectiveness and underlying mechanisms. We compared the impact of two designs implemented by the California Public Employees' Retirement System on inpatient hospital total hip or knee replacement: a reference-based pricing design for preferred provider organizations (PPOs) and a centers-of-excellence design for health maintenance organizations (HMOs). Payment and utilization data for the procedures in the period 2008-13 were evaluated using pre-post and quasi-experimental designs at the system and health plan levels, adjusting for demographic characteristics, case-mix, and other confounders. We found that both designs prompted higher use of designated low-price high-quality facilities and reduced average replacement expenses per member at the plan and system levels. However, the designs used different routes: The reference-based pricing design reduced average replacement payments per case in PPOs by 26.7 percent in the first year, compared to HMOs, but did not lower PPO members' utilization rates. In contrast, the centers-of-excellence design lowered HMO members' utilization rates by 29.2 percent in the first year, compared to PPOs, but did not reduce HMO average replacement payments per case. The reference-based pricing design appears more suitable for reducing price variation, and the centers-of-excellence design for addressing variation in use.

2015-09-01

To report and synthesize the perspectives, experiences, and preferences of stroke survivors undertaking inpatient physical rehabilitation through a systematic review of qualitative studies. MEDLINE, CINAHL, Embase, and PsycINFO were searched from database inception to February 2014. Reference lists of relevant publications were searched. All languages were included. Qualitative studies reporting stroke survivors' experiences of inpatient stroke rehabilitation were selected independently by 2 reviewers. The search yielded 3039 records; 95 full-text publications were assessed for eligibility, and 32 documents (31 studies) were finally included. Comprehensiveness and explicit reporting were assessed independently by 2 reviewers using the consolidated criteria for reporting qualitative research framework. Discrepancies were resolved by consensus. Data regarding characteristics of the included studies were extracted by 1 reviewer, tabled, and checked for accuracy by another reviewer. All text reported in studies' results sections were entered into qualitative data management software for analysis. Extracted texts were inductively coded and analyzed in 3 phases using thematic synthesis. Nine interrelated analytical themes, with descriptive subthemes, were identified that related to issues of importance to stroke survivors: (1) physical activity is valued; (2) bored and alone; (3) patient-centered therapy; (4) recreation is also rehabilitation; (5) dependency and lack of control; (6) fostering autonomy; (7) power of communication and information; (8) motivation needs nurturing; and (9) fatigue can overwhelm. The thematic synthesis provides new insights into stroke survivors' experiences of inpatient rehabilitation. Negative experiences were reported in all studies and include disempowerment, boredom, and frustration. Rehabilitation could be improved by increasing activity within formal therapy and in free time, fostering patients' autonomy through genuinely patient-centered care, and more effective communication and information. Future stroke rehabilitation research should take into account the experiences and preferences of stroke survivors. Copyright © 2015 American Congress of Rehabilitation Medicine.

Why do Alzheimer patients have difficulty with pronouns? Working memory, semantics, and reference in comprehension and production in Alzheimer's disease.

PubMed

1999-05-01

Three experiments investigated the extent to which semantic and working-memory deficits contribute to Alzheimer patients' impairments in producing and comprehending referring expressions. In Experiment 1, the spontaneous speech of 11 patients with Alzheimer's disease (AD) contained a greater ratio of pronouns to full noun phrases than did the spontaneous speech produced by 9 healthy controls. Experiments 2 and 3 used a cross-modal naming methodology to compare reference comprehension in another group of 10 patients and 10 age-matched controls. In Experiment 2, patients were less sensitive than healthy controls to the grammatical information necessary for processing pronouns. In Experiment 3, patients were better able to remember referent information in short paragraphs when reference was maintained with full noun phrases rather than pronouns, but healthy controls showed the reverse pattern. Performance in all three experiments was linked to working memory performance but not to word finding difficulty. We discuss these findings in terms of a theory of reference processing, the Informational Load Hypothesis, which views referential impairments in AD as the consequence of normal discourse processing in the context of a working memory impairment.

Consciousness: a unique way of processing information.

PubMed

Marchetti, Giorgio

2018-02-08

In this article, I argue that consciousness is a unique way of processing information, in that: it produces information, rather than purely transmitting it; the information it produces is meaningful for us; the meaning it has is always individuated. This uniqueness allows us to process information on the basis of our personal needs and ever-changing interactions with the environment, and consequently to act autonomously. Three main basic cognitive processes contribute to realize this unique way of information processing: the self, attention and working memory. The self, which is primarily expressed via the central and peripheral nervous systems, maps our body, the environment, and our relations with the environment. It is the primary means by which the complexity inherent to our composite structure is reduced into the "single voice" of a unique individual. It provides a reference system that (albeit evolving) is sufficiently stable to define the variations that will be used as the raw material for the construction of conscious information. Attention allows for the selection of those variations in the state of the self that are most relevant in the given situation. Attention originates and is deployed from a single locus inside our body, which represents the center of the self, around which all our conscious experiences are organized. Whatever is focused by attention appears in our consciousness as possessing a spatial quality defined by this center and the direction toward which attention is focused. In addition, attention determines two other features of conscious experience: periodicity and phenomenal quality. Self and attention are necessary but not sufficient for conscious information to be produced. Complex forms of conscious experiences, such as the various modes of givenness of conscious experience and the stream of consciousness, need a working memory mechanism to assemble the basic pieces of information selected by attention.

Each EXPRESS Rack provides eight Middeck Locker Equivalent locations and two drawer locations for powered experiment equipment, also referred to as sub-rack payloads. Payload developers may provide their own structure to occupy the equivalent volume of one, two, or four lockers as a single unit. Resources provided for each location include power (28 Vdc, 0-500 W), command and data handling (Ethernet, RS-422, 5 Vdc discrete, +/- 5 Vdc analog), video (NTSC/RS 170A), and air cooling (0-200 W). Each rack also provides water cooling (500 W) for two locations, one vacuum exhaust interface, and one gaseous nitrogen interface. Standard interfacing cables and hoses are provided on-orbit. One laptop computer is provided with each rack to control the rack and to accommodate payload application software. Four of the racks are equipped with the Active Rack Isolation System to reduce vibration between the ISS and the rack. EXPRESS Racks are operated by the Payload Operations Integration Center at Marshall Space Flight Center and the sub-rack experiments are operated remotely by the investigating organization. Payload Integration Managers serve as a focal to assist organizations developing payloads for an EXPRESS Rack. NASA provides EXPRESS Rack simulator software for payload developers to checkout payload command and data handling at the development site before integrating the payload with the EXPRESS Functional Checkout Unit for an end-to-end test before flight. EXPRESS Racks began supporting investigations onboard ISS on April 24, 2001 and will continue through the life of the ISS.

Power modulates over-reliance on false cardiac arousal when judging target attractiveness: the powerful are more centered on their own false arousal than the powerless.

PubMed

Jouffre, Stéphane

2015-01-01

Individuals attempting to label their emotions look for a plausible source of their physiological arousal. Co-occurrence of plausible sources can lead to the misattribution of real (or bogus) physiological arousal, resulting in physically attractive individuals being perceived as more attractive than they actually are. In two experiments, female participants heard bogus heart rate feedback while viewing photos of attractive male models. Compared with low-power and control participants, high-power participants rated reinforced photos (increased heart rate) more attractive than non-reinforced photos (stable heart rate) to a greater extent when they heard their own bogus heart rate feedback (Experiments 1 and 2) and to a lesser extent when they heard a recording of another participant's heart rate (Experiment 2). These findings, which suggest that power increases the tendency to misattribute one's physiological arousal to physically attractive individuals, are discussed with reference to theories linking power and social perception. © 2014 by the Society for Personality and Social Psychology, Inc.

Exploring infertile women's experiences about sexual life: A qualitative study.

Infertility is a serious problem in a couple's life that affects their marriage relationships. So, dissatisfaction with sexual function resulting from interpersonal problems is common among these couples. This qualitative study aimed to explore the experiences of infertile women in their sexual life. This is a qualitative study with a phenomenological approach. The participants were 20 infertile women referring to the health care centers and infertility clinics of Isfahan and were selected through purposive sampling. Data were collected by tape recording of deep interviews and analyzed by Colaizzi's method. Analysis of the participants' experiences led to five main concepts: "Disturbed in femininity-body image," "discouragement of sexual relations," "sacrifice of sexual pleasure for the sake of getting pregnant," "confusion in sexual relation during infertility treatment," and "striving to protect their marriage." Findings revealed that infertility affects women's different aspects of sexual life, especially disturbance in femininity-body image and sexual reluctance. With regard to women's willingness to protect their matrimonial life and prevent sexual trauma as a destroying factor for their family's mental health, it seems sexual counseling is necessary for infertile couples.

Effects of object asymmetry on visual attention.

PubMed

Maguire, Anne M; Bates, Timothy C; Boycott, Noël; Corballis, Michael C

2002-01-01

Unilateral neglect has been demonstrated relative to the intrinsic left side of objects, even when presented in the preserved hemispace. These results have been interpreted as evidence of an object-centered reference frame. In the present study, neurologically normal individuals were presented with letter stimuli having distinguishing features to the right (R) or left (J) of their intrinsic midline, shown in normal and mirror parity, and in six angle rotations. RTs confirmed that participants rotated the letters to the upright to decide parity: such rotation would align the object-centered and viewer-centered frames of reference, suggesting that not controlling for mental rotation would confound this effect. In addition, a dot, presented lateral to the main letter stimulus, resulted in quicker parity decisions when on the maximally-informative side of the letter. Together, the results suggest that apparent object-centered neglect may arise from the combined effects of mental rotation and within-object information asymmetries.

To describe the Reference Centers for Special Immunobiologicals and evaluate their implementation considering formal regulations. We conducted a program evaluation, of evaluative research type. From August 2011 to January 2012, a questionnaire was applied to the 42 Reference Centers for Special Immunobiologicals existing in the Country, approaching the structure, human resources, and developed activities dimensions. We conducted a descriptive analysis of data and used a clustering for binary data with the squared Euclidean distance, by the farthest neighbor method, to aggregate services with similar features. We observed great diversity among the services in the three dimensions. The clustering resulted in five service profiles, named according to their characteristics. 1) Best structure: 12 Reference Centers for Special Immunobiologicals with the highest proportion of services with the minimum of rooms recommended, purpose-built vaccine refrigerators, preventive maintenance of the cold chain, and oxygen source. 2) Immunobiologicals distributor: six Reference Centers for Special Immunobiologicals that distributed more than applied immunogens; no doctor present for more than half of the working hours and no purpose-built vaccine refrigerators . 3) Incipient implementation: five Reference Centers for Special Immunobiologicals with inadequate structure, such as absence of purpose-built vaccine refrigerators, preventive maintenance of the cold chain and oxygen source; none had computer. 4) Vaccination rooms: 13 Reference Centers for Special Immunobiologicals, everyone did routine immunization, most participated in vaccination campaigns. 5) Teaching and research: six services, all inserted into teaching hospitals, developed researches and received trainees; most had doctors in more than half of the working hours. The evaluation of the Reference Centers for Special Immunobiologicals implementation was based on the profiles found and considered the official regulations: services categorized as "better structure" and "teaching and research" were considered implemented; "immunobiologicals distributor" and "vaccination room" services, partially implemented, and the ones with the "incipient implementation" profile, not implemented. The results of this evaluation can contribute to the reformulation of the services, considering the current context. Descrever os Centros de Referência para Imunobiológicos Especiais e avaliar sua implantação considerando as regulamentações formais. Foi realizada uma avaliação de programa, tipo pesquisa avaliativa. De agosto de 2011 a janeiro de 2012, foi aplicado questionário aos responsáveis pelos 42 Centros de Referência para Imunobiológicos Especiais existentes no País, abordando as dimensões estrutura, recursos humanos e atividades desenvolvidas. Foi feita análise descritiva dos dados e utilizado agrupamento para dados binários com uso da distância euclidiana quadrática, pelo método do vizinho mais distante, para agregar serviços com características semelhantes. Observou-se grande diversidade entre os serviços nas três dimensões. O agrupamento resultou em cinco perfis de serviços, denominados de acordo com suas características. 1) Melhor estrutura: 12 Centros de Referência para Imunobiológicos Especiais com a maior proporção de serviços com o mínimo de salas preconizado, câmaras de vacinas, manutenção preventiva da rede de frio e fonte de oxigênio. 2) Dispensador de imunobiológicos: seis Centros de Referência para Imunobiológicos Especiais que mais dispensavam do que aplicavam imunógenos; sem médico presente por mais da metade do expediente do serviço e sem câmara de vacinas. 3) Implantação incipiente: cinco Centros de Referência para Imunobiológicos Especiais com estrutura inadequada, como ausência de câmaras de vacinas, de manutenção preventiva da rede de frio e de fonte de oxigênio; nenhum possuía computador. 4) Sala de vacinas: 13 Centros de Referência para Imunobiológicos Especiais, todos faziam imunização de rotina, a maioria participava de campanhas de vacinação. 5) Ensino e pesquisa: seis serviços, todos inseridos em hospitais de ensino, desenvolviam pesquisas e recebiam estagiários; a maioria possuía médicos em mais da metade do expediente. A avaliação de implantação dos Centros de Referência para Imunobiológicos Especiais baseou-se nos perfis encontrados e considerou as regulamentações oficiais: os serviços categorizados como "melhor estrutura" e "ensino e pesquisa" foram considerados implantados; os serviços "dispensador de imunobiológicos" e "sala de vacinas", parcialmente implantados e os do perfil "implantação incipiente", não implantados. Os resultados dessa avaliação podem contribuir para a reformulação dos serviços, considerando o contexto atual.

Installing each array is a 3-day process and includes a functional deployment test. The Gravity Probe B mission is a relativity experiment developed by NASA’s Marshall Space Flight Center, Stanford University and Lockheed Martin. The spacecraft will test two extraordinary predictions of Albert Einstein’s general theory of relativity that he advanced in 1916: the geodetic effect (how space and time are warped by the presence of the Earth) and frame dragging (how Earth’s rotation drags space and time around with it). Gravity Probe B consists of four sophisticated gyroscopes that will provide an almost perfect space-time reference system. The mission will look in a precision manner for tiny changes in the direction of spin.

Thermal and Chemical Characterization of Composite Materials. MSFC Center Director's Discretionary Fund Final Report, Project No. ED36-18

Stanley, D. C.; Huff, T. L.

2003-01-01

The purpose of this research effort was to: (1) provide a concise and well-defined property profile of current and developing composite materials using thermal and chemical characterization techniques and (2) optimize analytical testing requirements of materials. This effort applied a diverse array of methodologies to ascertain composite material properties. Often, a single method of technique will provide useful, but nonetheless incomplete, information on material composition and/or behavior. To more completely understand and predict material properties, a broad-based analytical approach is required. By developing a database of information comprised of both thermal and chemical properties, material behavior under varying conditions may be better understood. THis is even more important in the aerospace community, where new composite materials and those in the development stage have little reference data. For example, Fourier transform infrared (FTIR) spectroscopy spectral databases available for identification of vapor phase spectra, such as those generated during experiments, generally refer to well-defined chemical compounds. Because this method renders a unique thermal decomposition spectral pattern, even larger, more diverse databases, such as those found in solid and liquid phase FTIR spectroscopy libraries, cannot be used. By combining this and other available methodologies, a database specifically for new materials and materials being developed at Marshall Space Flight Center can be generated . In addition, characterizing materials using this approach will be extremely useful in the verification of materials and identification of anomalies in NASA-wide investigations.

Understanding Patient Barriers to Kidney Transplant Evaluation.

Dageforde, Leigh Anne; Box, Amanda; Feurer, Irene D; Cavanaugh, Kerri L

2015-07-01

Some patients referred for kidney transplant evaluation fail to attend the visit. Our goal was to compare demographic, socioeconomic, and psychologic factors between evaluation visit attendees and absentees. A convenience sample of patients referred and scheduled for kidney transplant evaluation at a single center from November 2012 to December 2013 participated in a phone survey reporting socioeconomic, demographic, and clinical characteristics; health literacy; and perceived knowledge and concerns about transplantation. Absentees were matched by race with attendees. Analyses of differences between groups were performed with chi-square test, Fisher exact test, and t tests. Multivariable logistic regression was adjusted for relevant demographic characteristics. One hundred four adults participated (61% men, 46% white, 52 ± 12 years). Financial concerns were the most prevalent (67.3% affording medication, 64.1% affording operation). Previous evaluation at a different transplant center (P = 0.029) and being on dialysis (P = 0.008) were significantly associated with absence. Attendance was associated with concerns about finding a living donor (P = 0.038) and higher perceived general knowledge about transplantation (P ≤ 0.001). No differences were appreciated in demographic, socioeconomic, or health literacy factors between groups. Both attendee and absentee patients were most concerned with the financial burden of kidney transplantation. Although concerns and perceived knowledge are important correlates of behavior, other considerations such as psychologic factors and prior medical experiences may influence patients' ability to complete the kidney transplant evaluation process. Although this pilot study was conducted in a small sample and has limited generalizability, our findings can guide future research.

Daily therapeutic plasma exchange (TPE) and rituximab improved thrombotic thrombocytopenic purpura (TTP) prognosis. In the more severe cases, salvage therapies including twice-daily TPE and/or cyclophosphamide may be proposed and require evaluation. TTP was defined as a thrombotic microangiopathy (TMA) with severe (<10%) acquired ADAMTS13 deficiency. Among patients included in the French Reference Center for TMA registry, we considered those with a severe disease (i.e., unresponsive to daily TPE and rituximab) who received twice-daily TPE. Nineteen of 289 (6.6%) patients with TTP were treated by twice-daily TPE between 2008 and 2014. Twice-daily TPE was associated with rituximab in 16 cases. The median duration of twice-daily TPE treatment was 3 d (2-22 d). In 6 patients (31.6%), additional treatments (mainly pulses of cyclophosphamide) were performed because of a persistently refractory disease (4 cases) or an exacerbation (2 cases), despite twice-daily TPE. Only one patient (5.3%) died. The other 18 achieved a durable complete remission 25.5 d (13-68 d) after the first TPE. The median follow-up was 14.4 months (7 d-45 months). Twice-daily TPE may be an efficient strategy in the more severe TTP patients with a short-term life-threatening disease that could overcome their poor prognosis. © 2015 John Wiley & Sons A/S.

The identification of families at-risk for hereditary cancer is extremely important due to the prevention potential in those families. However, the number of Brazilian genetic services providing oncogenetic care is extremely low for the continental dimension of the country and its population. Therefore, at-risk patients do not receive appropriate assistance. This report describes the creation, structure and management of a cancer genetics service in a reference center for cancer prevention and treatment, the Barretos Cancer Hospital (BCH). The Oncogenetics Department (OD) of BCH offers, free of charge, to all patients/relatives with clinical criteria, the possibility to perform i) genetic counseling, ii) preventive examinations and iii) genetic testing with the best quality standards. The OD has a multidisciplinary team and is integrated with all specialties. The genetic counseling process consists (mostly) of two visits. In 2014, 614 individuals (371 families) were seen by the OD. To date, over 800 families were referred by the OD for genetic testing. The support provided by the Oncogenetics team is crucial to identify at-risk individuals and to develop preventive and personalized behaviors for each situation, not only to the upper-middle class population, but also to the people whose only possibility is the public health system.

Data Identifiers and Citations Enable Reproducible Science

NASA Astrophysics Data System (ADS)

Tilmes, C.

2011-12-01

Modern science often involves data processing with tremendous volumes of data. Keeping track of that data has been a growing challenge for data center. Researchers who access and use that data don't always reference and cite their data sources adequately for consumers of their research to follow their methodology or reproduce their analyses or experiments. Recent research has led to recommendations for good identifiers and citations that can help address this problem. This paper will describe some of the best practices in data identifiers, reference and citation. Using a simplified example scenario based on a long term remote sensing satellite mission, it will explore issues in identifying dynamic data sets and the importance of good data citations for reproducibility. It will describe the difference between granule and collection level identifiers, using UUIDs and DOIs to illustrate some recommendations for developing identifiers and assigning them during data processing. As data processors create data products, the provenance of the input products and precise steps that led to their creation are recorded and published for users of the data to see. As researchers access the data from an archive, they can use the provenance to help understand the genesis of the data, which could have effects on their usage of the data. By citing the data on publishing their research, others can retrieve the precise data used in their research and reproduce the analyses and experiments to confirm the results. Describing the experiment to a sufficient extent to reproduce the research enforces a formal approach that lends credibility to the results, and ultimately, to the policies of decision makers depending on that research.

[Being cared for and caring: living with multiple chronic diseases (Leila)-a qualitative study about APN contributions to integrated care].

Living with multiple chronic diseases is complex and leads to enhanced care needs. To foster integrated care a project called "Living with chronic disease" (Leila) was initiated. The aim was to develop an Advanced Practice Nursing (APN) service in collaboration with medical centers for persons who are living with multiple chronic diseases. The following research questions were addressed: 1. What are patients' experiences, referring physicians and APNs with the Leila-Service? 2. How are referral processes performed? 3. How do the involved groups experience collaboration and APN role development? A qualitative approach according grounded theory of Corbin and Strauss was used to explore the experiences with the Leila project and the interaction of the persons involved. 38 interviews were conducted with patients who are living with multiple chronic diseases, their APN's and the referring physicians. The findings revealed "Being cared for and caring" as main category. The data demonstrated how patients responded to their involvement into care and that they were taken as serious partners in the care process. The category "organizing everyday life" describes how patients learned to cope with the consequences of living with multiple chronic diseases. "Using all resources" as another category demonstrates how capabilities and strengths were adopted. The results of the cooperation- and allocation processes showed that the APN recognition and APN role performance have to be negotiated. Prospective APN-services for this patient population should be integrated along with physician networks and other service providers including community health nursing.

The effect of interaural fluctuation rate on correlation change discrimination.

PubMed

Goupell, Matthew J; Litovsky, Ruth Y

2014-02-01

While bilateral cochlear implants (CIs) provide some binaural benefits, these benefits are limited compared to those observed in normal-hearing (NH) listeners. The large frequency-to-electrode allocation bandwidths (BWs) in CIs compared to auditory filter BWs in NH listeners increases the interaural fluctuation rate available for binaural unmasking, which may limit binaural benefits. The purpose of this work was to investigate the effect of interaural fluctuation rate on correlation change discrimination and binaural masking-level differences in NH listeners presented a CI simulation using a pulsed-sine vocoder. In experiment 1, correlation-change just-noticeable differences (JNDs) and tone-in-noise thresholds were measured for narrowband noises with different BWs and center frequencies (CFs). The results suggest that the BW, CF, and/or interaural fluctuation rate are important factors for correlation change discrimination. In experiment 2, the interaural fluctuation rate was systematically varied and dissociated from changes in BW and CF by using a pulsed-sine vocoder. Results indicated that the interaural fluctuation rate did not affect correlation change JNDs for correlated reference noises; however, slow interaural fluctuations increased correlation change JNDs for uncorrelated reference noises. In experiment 3, the BW, CF, and vocoder pulse rate were varied while interaural fluctuation rate was held constant. JNDs increased for increasing BW and decreased for increasing CF. In summary, relatively fast interaural fluctuation rates are not detrimental for detecting changes in interaural correlation. Thus, limiting factors to binaural benefits in CI listeners could be a result of other temporal and/or spectral deficiencies from electrical stimulation.

Skylab

NASA Image and Video Library

1973-01-01

The rate of neutron flow is commonly referred to as a flux. The measurement of neutron fluxes in Skylab was the subject of a proposal by Terry Quist of San Antonio, Texas. This chart describes Quist's experiment, Neutron Analysis, Skylab student experiment ED-76. These measurements were considered important not only by NASA but also by the scientific community for four reasons. High energy neutrons can be harmful to human tissue if they are present in significant quantities. Fluxes of neutrons can damage film and other sensitive experimental equipment in a marner similar to those produced by x-rays or other radiation. Furthermore, neutron fluxes can be used as a calibration source for other space-oriented particle physics experiments. Finally, neutron fluxes can affect sensitive x-ray and gamma-ray astronomy observations. Quist's objectives were to measure the neutron fluxes present in Skylab and, with the assistance of NASA and other physicists, to attempt determination of their origin as well as their energy range or spectrum. This experiment had stimulated interest in further studies of neutron phenomena in space. In March 1972, NASA and the National Science Teachers Association selected 25 experiment proposals for flight on Skylab. Science advisors from the Marshall Space Flight Center aided and assisted the students in developing the proposals for flight on Skylab.

Ecology-centered experiences among children and adolescents: A qualitative and quantitative analysis

NASA Astrophysics Data System (ADS)

Orton, Judy

The present research involved two studies that considered ecology-centered experiences (i.e., experiences with living things) as a factor in children's environmental attitudes and behaviors and adolescents' ecological understanding. The first study (Study 1) examined how a community garden provides children in an urban setting the opportunity to learn about ecology through ecology-centered experiences. To do this, I carried out a yearlong ethnographic study at an urban community garden located in a large city in the Southeastern United States. Through participant observations and informal interviews of community garden staff and participants, I found children had opportunities to learn about ecology through ecology-centered experiences (e.g., interaction with animals) along with other experiences (e.g., playing games, reading books). In light of previous research that shows urban children have diminished ecological thought---a pattern of thought that privileges the relationship between living things---because of their lack of ecology-centered experiences (Coley, 2012), the present study may have implications for urban children to learn about ecology. As an extension of Study 1, I carried out a second study (Study 2) to investigate how ecology-centered experiences contribute to adolescents' environmental attitudes and behaviors in light of other contextual factors, namely environmental responsibility support, ecological thought, age and gender. Study 2 addressed three research questions. First, does ecological thought---a pattern of thought that privileges the relationship between living things---predict environmental attitudes and behaviors (EAB)? Results showed ecological thought did not predict EAB, an important finding considering the latent assumptions of previous research about the relationship between these two factors (e.g., Brugger, Kaiser, & Roczen, 2011). Second, do two types of contextual support, ecology-centered experiences (i.e., experiences with living things) and environmental responsibility support (i.e., support through the availability of environmentally responsible models) predict EAB? As predicted, results showed that ecology-centered experiences predicted EAB; yet, when environmental responsibility support was taken into consideration, ecology-centered experiences no longer predicted EAB. These findings suggested environmental responsibility support was a stronger predictor than ecology-centered experiences. Finally, do age and gender predict EAB? Consistent with previous research (e.g., Alp, Ertepiner, Tekkaya, & Yilmaz, 2006), age and gender significantly predicted EAB.

2006-01-01

Structured emergency department (ED) triage scales can be used to develop patient referral strategies from the ED to primary care. The objectives of the present study were to evaluate the percentage of patients who could potentially be referred from triage to primary care and to describe their clinical characteristics. We analyzed all patients with low acuity (triage levels IV and V) and low complexity (patients discharged from the ED) triaged during 2003 with the Andorran Triage Model in the ED and estimated the percentage of patients who could potentially be referred on the basis of three primary care models: A, centers unable to deal with emergencies or perform complementary investigations; B, centers able to deal with emergencies and perform complementary investigations, and C, centers able to deal with emergencies but unable to perform complementary investigations. Of the 25,319 patients included in the study, 5.63% could be referred to model A, 75.22% to model B and 33.36% to model C. A total of 81.04% of these model C patients were classified in seven symptomatic categories: wounds and traumatisms, inflammation or fever, pediatric problems, rhinolaryngological infection or alterations, ocular symptoms, pain and cutaneous allergy or reactions. Casemix analysis, based on the level of acuity and discharge criteria, can be used to establish the percentage of patients that could potentially be referred to primary care. Analysis of their clinical profile is useful to design referral protocols.

Memory systems interaction in the pigeon: working and reference memory.

PubMed

Roberts, William A; Strang, Caroline; Macpherson, Krista

2015-04-01

Pigeons' performance on a working memory task, symbolic delayed matching-to-sample, was used to examine the interaction between working memory and reference memory. Reference memory was established by training pigeons to discriminate between the comparison cues used in delayed matching as S+ and S- stimuli. Delayed matching retention tests then measured accuracy when working and reference memory were congruent and incongruent. In 4 experiments, it was shown that the interaction between working and reference memory is reciprocal: Strengthening either type of memory leads to a decrease in the influence of the other type of memory. A process dissociation procedure analysis of the data from Experiment 4 showed independence of working and reference memory, and a model of working memory and reference memory interaction was shown to predict the findings reported in the 4 experiments.

PURPOSE We sought to assess patients’ ratings of patient-centered medical home (PCMH) attributes and overall quality of care within federally supported health centers. METHODS Data were collected through the 2009 Health Center Patient Survey (n = 4,562), which consisted of in-person interviews and included a nationally representative sample of patients seen in health centers. Quality measures included patients’ perceptions of overall quality of services, perceptions of quality of clinician advice/treatment, and likelihood of referring friends and relatives to the health center. PCMH attributes included (1) access to care getting to health center, (2) access to care during visit, (3) patient-centered communication with health care clinicians, (4) patient-centered communication with support staff, (5) self-management support for chronic conditions, (6) self-management support for behavioral risks, and (7) comprehensive preventive care. Bivariate analysis and logistic regressions were used to examine associations between patients’ perceptions of PCMH attributes and patient-reported quality of care. RESULTS Eighty-four percent of patients reported excellent/very good overall quality of services, 81% reported excellent/very good quality of clinician care, and 84% were very likely to refer friends and relatives. Higher patient ratings on the access to care and patient-centered communication attributes were associated with higher odds of patient-reported high quality of care on the 3 outcome measures. CONCLUSIONS More than 80% of patients perceived high quality of care in health centers. PCMH attributes related to access to care and communication were associated with greater likelihood of patients reporting high-quality care. PMID:24218374

We aimed to determine the pattern of drug use and the affective demographic factors in addicts in self-referred drug rehabilitation centers in Khuzestan province. It was a cross-sectional descriptive and analytic study which has done on 4400 addicts in self-referred drug rehabilitation centers in Khuzestan province from March 2014 to March 2015. The collected data were analyzed in SPSS version 22 software. Mean and standard deviation were calculated for continuous variables and the frequency and percentage frequency were calculated for nominal and classified variables, and also t-test, χ2 and ANOVA were used to examine the relationships between variables. The level of significance was considered less than 0.05. Finding has shown that 97.5% were male. The average age of subjects was 38.21 ±10.52. Most consumable drug in these people was opium (50.6%) and the main way of drug use was smoking (69.4%). In terms of motivation of using drug, in men were enjoyment and in women family problems had the highest relative percentage. The majority of subjects (67.2%) had a history of drug abandonment. The reason of referring to rehabilitation centers for treatment, types of using drug and the number of drug using, was significant difference between males and females (p < 0.05). The results have shown that it is necessary to consider some issues including of provincial drug policy and increasing awareness at different levels of society and making appropriate cultural and sports spaces in order to achieve the primary preventive goals.

Physical-technical quality assurance is one of the essential tasks of the National Reference Centers in the German Breast Cancer Screening Program. For this purpose the mammography units are required to transfer the measured values of the constancy tests on a daily basis and all phantom images created for this purpose on a weekly basis to the reference centers. This is a serious logistical challenge. To meet these requirements, we developed an innovative software tool. By the end of 2005, we had already developed web-based software (MammoControl) allowing the transmission of constancy test results via entry forms. For automatic analysis and transmission of the phantom images, we then introduced an extension (MammoControl DIANA). This was based on Java, Java Web Start, the NetBeans Rich Client Platform, the Pixelmed Java DICOM Toolkit and the ImageJ library. MammoControl DIANA was designed to run locally in the mammography units. This allows automated on-site image analysis. Both results and compressed images can then be transmitted to the reference center. We developed analysis modules for the daily and monthly consistency tests and additionally for a homogeneity test. The software we developed facilitates the immediate availability of measurement results, phantom images, and DICOM header data in all reference centers. This allows both targeted guidance and short response time in the case of errors. We achieved a consistent IT-based evaluation with standardized tools for the entire screening program in Germany. © Georg Thieme Verlag KG Stuttgart · New York.

Gravity Influences the Visual Representation of Object Tilt in Parietal Cortex

PubMed Central

Angelaki, Dora E.

2014-01-01

Sensory systems encode the environment in egocentric (e.g., eye, head, or body) reference frames, creating inherently unstable representations that shift and rotate as we move. However, it is widely speculated that the brain transforms these signals into an allocentric, gravity-centered representation of the world that is stable and independent of the observer's spatial pose. Where and how this representation may be achieved is currently unknown. Here we demonstrate that a subpopulation of neurons in the macaque caudal intraparietal area (CIP) visually encodes object tilt in nonegocentric coordinates defined relative to the gravitational vector. Neuronal responses to the tilt of a visually presented planar surface were measured with the monkey in different spatial orientations (upright and rolled left/right ear down) and then compared. This revealed a continuum of representations in which planar tilt was encoded in a gravity-centered reference frame in approximately one-tenth of the comparisons, intermediate reference frames ranging between gravity-centered and egocentric in approximately two-tenths of the comparisons, and in an egocentric reference frame in less than half of the comparisons. Altogether, almost half of the comparisons revealed a shift in the preferred tilt and/or a gain change consistent with encoding object orientation in nonegocentric coordinates. Through neural network modeling, we further show that a purely gravity-centered representation of object tilt can be achieved directly from the population activity of CIP-like units. These results suggest that area CIP may play a key role in creating a stable, allocentric representation of the environment defined relative to an “earth-vertical” direction. PMID:25339732

Whisking mechanics and active sensing

Bush, Nicholas E; Solla, Sara A

We describe recent advances in quantifying the three-dimensional (3D) geometry and mechanics of whisking. Careful delineation of relevant 3D reference frames reveals important geometric and mechanical distinctions between the localization problem (‘where’ is an object) and the feature extraction problem (‘what’ is an object). Head-centered and resting-whisker reference frames lend themselves to quantifying temporal and kinematic cues used for object localization. The whisking-centered reference frame lends itself to quantifying the contact mechanics likely associated with feature extraction. We offer the ‘windowed sampling’ hypothesis for active sensing: that rats can estimate an object’s spatial features by integrating mechanical information across whiskers during brief (25–60 ms) windows of ‘haptic enclosure’ with the whiskers, a motion that resembles a hand grasp.

Novel process for production of micro lenses with increased centering accuracy and imaging performance

NASA Astrophysics Data System (ADS)

Wilde, C.; Langehanenberg, P.; Schenk, T.

2017-10-01

For modern production of micro lens systems, such as cementing of doublets or more lenses, precise centering of the lens edge is crucial. Blocking the lens temporarily on a centering arbor ensures that the centers of all optical lens surfaces coincide with the lens edge, while the arbor's axis serves as reference for both alignment and edging process. This theoretical assumption of the traditional cementing technology is not applicable for high-end production. In reality cement wedges between the bottom lens surface and the arbor's ring knife edge may occur and even expensive arbors with single-micron precision suffer from reduced quality of the ring knife edge after multiple usages and cleaning cycles. Consequently, at least the position of the bottom lens surface is undefined and the optical axis does not coincide with the arbor's reference axis! In order to overcome this basic problem in using centering arbors, we present a novel and efficient technique which can measure and align both surfaces of a lens with respect to the arbor axis with high accuracy and furthermore align additional lenses to the optical axis of the bottom lens. This is accomplished by aligning the lens without mechanical contact to the arbor. Thus the lens can be positioned in four degrees of freedom, while the centration errors of all lens surfaces are measured and considered. Additionally the arbor's reference axis is not assumed to be aligned to the rotation axis, but simultaneously measured with high precision.

Patient-Centered Specialty Practice: Defining the Role of Specialists in Value-Based Health Care.

Health care is at a crossroads and under pressure to add value by improving patient experience and health outcomes and reducing costs to the system. Efforts to improve the care model in primary care, such as the patient-centered medical home, have enjoyed some success. However, primary care accounts for only a small portion of total health-care spending, and there is a need for policies and frameworks to support high-quality, cost-efficient care in specialty practices of the medical neighborhood. The Patient-Centered Specialty Practice (PCSP) model offers ambulatory-based specialty practices one such framework, supported by a formal recognition program through the National Committee for Quality Assurance. The key elements of the PCSP model include processes to support timely access to referral requests, improved communication and coordination with patients and referring clinicians, reduced unnecessary and duplicative testing, and an emphasis on continuous measurement of quality, safety, and performance improvement for a population of patients. Evidence to support the model remains limited, and estimates of net costs and value to practices are not fully understood. The PCSP model holds promise for promoting value-based health care in specialty practices. The continued development of appropriate incentives is required to ensure widespread adoption.

An experienced senior vascular surgeon, Dr H. O. Nest, at a university medical center is asked to evaluate a patient with a rare complex vascular problem. The patient is a high-ranking university official, Mr N. Otable, well known to all in the university setting. Dr Nest has had very limited experience with the condition. He has viewed presentations about it but is aware of a world expert at another institution. He discusses transfer with the patient, who agrees on that approach. Later that day, when Dr Nest receives a visit from the Chief-of-Staff and the hospital CEO asking about Mr Otable, they are very concerned that transfer will reflect badly on the medical center's reputation. Dr Nest is strongly requested to reconsider his recommendation--almost at gunpoint. What should he do? A. If he believes that the outcome will be satisfactory, he should schedule the operation. B. He should explain the situation to the patient and let him choose where he wishes to have his surgery. C. He should continue with the plan to refer the patient to another center. D. He must understand his limits and base his decision accordingly. E. He should arrange a conference with the surgeons in the vascular division and the administrators.

The significance of the quadratic Doppler effect for space travel and astrophysics

NASA Astrophysics Data System (ADS)

Boehm, M.

1985-09-01

It is shown that a distinct frame of reference exists for light for which the Kennedy-Thorndike experiment provides unequivocal evidence. This leads to the postulate of a rotating instead of an expanding universe. It is shown that the cosmic red shift can be understood as the result of a Coriolis acceleration of the light propagating between two arbitrary points of different gravitational potential. Methods for determining the angular velocity of the rotating universe are given, and it is discussed whether the speed of light and the gravitational constant are universal constants or whether they are functions of distance from the center of the universe. Suggestions are made for further experimental studies and for practical application of the quadratic Doppler effect.

Shuttle derived atmospheric density model. Part 2: STS atmospheric implications for AOTV trajectory analysis, a proposed GRAM perturbation density model

NASA Technical Reports Server (NTRS)

Findlay, J. T.; Kelly, G. M.; Troutman, P. A.

1984-01-01

A perturbation model to the Marshall Space Flight Center (MSFC) Global Reference Atmosphere Model (GRAM) was developed for use in the Aeroassist Orbital Transfer Vehicle (AOTV) trajectory and analysis. The model reflects NASA Space Shuttle experience over the first twelve entry flights. The GRAM was selected over the Air Force 1978 Reference Model because of its more general formulation and wider use throughout NASA. The add-on model, a simple scaling with altitude to reflect density structure encountered by the Shuttle Orbiter was selected principally to simplify implementation. Perturbations, by season, can be utilized to minimize the number of required simulations, however, exact Shuttle flight history can be exercised using the same model if desired. Such a perturbation model, though not meteorologically motivated, enables inclusion of High Resolution Accelerometer Package (HiRAP) results in the thermosphere. Provision is made to incorporate differing perturbations during the AOTV entry and exit phases of the aero-asist maneuver to account for trajectory displacement (geographic) along the ground track.

Creating a web-based digital photographic archive: one hospital library's experience.

PubMed

Marshall, Caroline; Hobbs, Janet

2017-04-01

Cedars-Sinai Medical Center is a nonprofit community hospital based in Los Angeles. Its history spans over 100 years, and its growth and development from the merging of 2 Jewish hospitals, Mount Sinai and Cedars of Lebanon, is also part of the history of Los Angeles. The medical library collects and maintains the hospital's photographic archive, to which retiring physicians, nurses, and an active Community Relations Department have donated photographs over the years. The collection was growing rapidly, it was impossible to display all the materials, and much of the collection was inaccessible to patrons. The authors decided to make the photographic collection more accessible to medical staff and researchers by purchasing a web-based digital archival package, Omeka. We decided what material should be digitized by analyzing archival reference requests and considering the institution's plan to create a Timeline Wall documenting and celebrating the history of Cedars-Sinai. Within 8 months, we digitized and indexed over 500 photographs. The digital archive now allows patrons and researchers to access the history of the hospital and enables the library to process archival references more efficiently.

We aimed to evaluate the incremental cost-effectiveness of engaging private practitioners (PPs) to refer tuberculosis (TB) suspects to public health centers in Jogjakarta, Indonesia. Effectiveness was assessed for TB suspects notified between May 2004 and April 2005. Private practitioners referred 1,064 TB suspects, of which 57.5% failed to reach a health center. The smear-positive rate among patients reaching a health center was 61.8%. Two hundred eighty (280) out of a total of 1,306 (21.4%) new smear-positive cases were enrolled through the PPs strategy. The incremental cost-effectiveness ratio per smear-positive case successfully treated for the PPs strategy was US$351.66 (95% CI 322.84–601.33). On the basis of an acceptability curve using the National TB control program's willingness-to-pay threshold (US$448.61), we estimate the probability that the PPs strategy is cost-effective at 66.8%. The strategy of engaging PPs was incrementally cost-effective, although under specific conditions, most importantly a well-functioning public directly observed treatment, short-course (DOTS) program.

Thrombotic microangiopathies (TMA) represent rare diseases requiring a high skill for their management that deserved in France the identification of a dedicated National reference center. TMA are short-term life-threatening diseases; however, with an adapted management, their prognosis can be excellent. It is therefore mandatory to recognize and treat them rapidly according to standard guidelines. Telemedicine is a specialized hub consisting of highly skilled staff trained in a specific domain of medicine. The telemedicine activity of a reference center is an important representative indicator of its expertise and recourse ability. It requires to be accurately evaluated and promoted. In this work, we report the French reference center for TMA telemedicine activity since its setting-up. TMA represent an interesting model of diseases that required a specific organization of telemedicine activity to adapt to clinicians demand, which includes particularly the need to answer resorts in real time 24/7.

In two studies, we investigated the memory underpinnings of future intentions related to past hedonic experiences. Preceding research did not make clear whether the specific memory processes supporting the expression of intentions about the future involve global judgments of the past experience (general affective evaluations formed on-line) or judgments derived from the episodic recollection of the past. Adapting a correlational paradigm previously employed to study future intentions, and applying it to the experience of watching a movie, we comparatively tested the influence of global retrospective evaluations vs. episodic-derived evaluations on future intentions. In Study 1, in which the intentions involved a future experience that was very similar to an overall past one (e.g., seeing the movie sequel), the findings showed that participants relied only on global judgments to form future intentions. In Study 2, in which the global judgment on the past was less diagnostic because the future intentions referred to specific parts of the past experience (e.g., watching a movie centered on a minor character in the previously seen movie), the results indicated that relevant episodic memories provided an essential contribution to the prediction of future intentions. These findings are in agreement with the predictions of the accessibility-diagnosticity framework and they show that global judgments and episodic memories of a past experience contribute differentially to diverse kinds of future intentions.

In quantitative gene expression analysis, normalization using a reference gene as an internal control is frequently performed for appropriate interpretation of the results. Efforts have been devoted to exploring superior novel reference genes using microarray transcriptomic data and to evaluating commonly used reference genes by targeting analysis. However, because the number of specifically detectable genes is totally dependent on probe design in the microarray analysis, exploration using microarray data may miss some of the best choices for the reference genes. Recently emerging RNA sequencing (RNA-seq) provides an ideal resource for comprehensive exploration of reference genes since this method is capable of detecting all expressed genes, in principle including even unknown genes. We report the results of a comprehensive exploration of reference genes using public RNA-seq data from plants such as Arabidopsis thaliana (Arabidopsis), Glycine max (soybean), Solanum lycopersicum (tomato) and Oryza sativa (rice). To select reference genes suitable for the broadest experimental conditions possible, candidates were surveyed by the following four steps: (1) evaluation of the basal expression level of each gene in each experiment; (2) evaluation of the expression stability of each gene in each experiment; (3) evaluation of the expression stability of each gene across the experiments; and (4) selection of top-ranked genes, after ranking according to the number of experiments in which the gene was expressed stably. Employing this procedure, 13, 10, 12 and 21 top candidates for reference genes were proposed in Arabidopsis, soybean, tomato and rice, respectively. Microarray expression data confirmed that the expression of the proposed reference genes under broad experimental conditions was more stable than that of commonly used reference genes. These novel reference genes will be useful for analyzing gene expression profiles across experiments carried out under various experimental conditions.

The study investigated, through a literature review, how the research community has addressed the difficulties experiences by the teams in front of new prescriptions for the treatment of alcohol and drug users in Centers of Psyco-social Attention and discusses the relevance of the conceptual and methodological references of Ergonomics for understand and transform work situations. Such studies tend to do an analysis that does not account for variability present in both the workers and work organization and prioritize the analysis of final results of the, disqualifying local inventions due to tasks imposed by policy guidelines. It is estimated that the Ergonomics, considering the diversity of training, learning and experience, contributes to the implementation of media to promote the continued development of competences that can meet the demands of production and expands knowledge about the problems experienced and the possibilities of overcoming them.

Hundreds of satellites have been launched to date. Some have operated extremely well and others have not. In order to learn from past operating experiences, a study was conducted to determine the conditions under which space mechanisms (mechanically moving components) have previously worked or failed. The study consisted of an extensive literature review that included both government contractor reports and technical journals, communication and visits (when necessary) to the various NASA and DOD centers and their designated contractors (this included contact with project managers of current and prior NASA satellite programs as well as their industry counterparts), requests for unpublished information to NASA and industry, and a mail survey designed to acquire specific mechanism experience. The information obtained has been organized into two volumes. Volume 1 provides a summary of the lesson learned, the results of a needs analysis, responses to the mail survey, a listing of experts, a description of some available facilities, and a compilation of references. Volume 2 contains a compilation of the literature review synopsis.

In 1995, the NASA Langley Research Center conducted a series of experimental measurements that characterized the electromagnetic environment (EME) inside a Boeing 757 airliner while in flight, Measurements were made of the electromagnetic energy coupled into a commercially configured aircraft as it was flown in close proximity to ground-based radio frequency (RF) transmitters operating at approximately 26, 173. and 430 MHz. The goal of this experiment was to collect data for the verification of analytical predictions of the internal aircraft response to an external stimulus. This paper describes the experiment, presents the data collected by it, and discusses techniques used to compute both the magnitude of the electric field illuminating the aircraft and its direction of propagation relative to a coordinate system fixed to the aircraft. The latter is determined from Global Positioning System (GPS) and aircraft Inertial Reference Unit (IRU) data. The paper concludes with an examination of the shielding effectiveness of the test aircraft. as determined by comparison of' the measured internal EME and computed external EME.

Reevaluation of the NOAA/CMDL carbon monoxide reference scale and comparisons with CO reference gases at NASA-Langley and the Fraunhofer Institut

The carbon monoxide (CO) reference scale created by the National Oceanic and Atmospheric Administration/Climate Monitoring and Diagnostics Laboratory (NOAA/CMDL) is used to quantify measurements of CO in the atmosphere, calibrate standards of other laboratories and to otherwise provide reference gases to the community measuring atmospheric CO. This reference scale was created based upon a set of primary standards prepared by gravimetric methods at CMDL and has been propagated to a set of working standards. In this paper we compare CO mixing ratios assigned to the working standards by three approaches: (1) calibration against the original gravimetric standards, (2) calibration using only working standards as the reference gas, and (3) calibration against three new gravimetric standards prepared to CMDL. The agreement between these values was typically better than 1%. The calibration histories of CMDL working standards are reviewed with respect to expected rates of CO change in the atmosphere. Using a Monte Carlo approach to simulate the effect of drifting standards on calculated mixing ratios, we conclude that the error solely associated with the maintenance of standards will limit the ability to detect small CO changes in the atmosphere. We also report results of intercalibration experiments conducted between CMDL and the Diode Laser Sensor Group (DACOM) at the NASA Langley Research Center (Hampton, Virginia), and CMDL and the Fraunhofer-Institut (Garmisch-Partenkirchen, Germany). Each laboratory calibrated several working standards for CO using their reference gases, and these results were compared to calibrations conducted by CMDL.

Teaching style beliefs among U.S. and Israeli faculty.

PubMed

Behar-Horenstein, Linda S; Mitchell, Gail S; Notzer, Netta; Penfield, Randy; Eli, Ilana

2006-08-01

The purpose of this study was to determine if self-reported teaching style beliefs were different among faculty at a U.S. and an Israeli dental school. Teacher-centered practices refer to beliefs that the teacher holds the subject matter expertise and students are generally passive learners who must be told what to think. Student-centered practices refer to beliefs that students must learn how to construct their own understanding. Student-centered teaching is directed towards enabling students to think about complex issues. Twenty-seven of fifty-eight (47.37 percent) faculty at a dental school in the United States and thirty of thirty-four (88 percent) Israeli dental faculty teaching in basic science courses completed the Teaching Behavior Preferences Survey (TBPS). The TBPS is a thirty-item instrument that measures two domains of teaching styles--teacher-centered (TC) and student-centered (SC)--and four subdomains: methods of instruction (MI), classroom milieu (CM), use of questions (UQ), and use of assessment (UA). Findings revealed that there were no significant differences in student-centered and teacher-centered teaching practices and methods of instruction, classroom milieu, and use of questions. There was a significant difference between the U.S. and Israeli groups in their reported use of assessment. The U.S. faculty reported a greater preference for student-centered assessment practices than did the Israeli faculty.

Increased public awareness of autism spectrum disorders (ASD) and routine screening in primary care have contributed to increased requests for diagnostic ASD evaluations. However, given the scarcity of subspecialty autism diagnostic resources, overreferral of children suspected of having ASD may be contributing to long waiting lists at tertiary care autism centers and delaying diagnosis for those children who truly have ASD. To determine whether children are being excessively referred to ASD-specific diagnostic clinics, our objective was to determine the prevalence of true ASD diagnoses in children referred for diagnostic ASD evaluation. Charts of all patients referred to a regional autism center between April 2011 and August 2012 for suspicion of a possible ASD were retrospectively reviewed and demographic and clinical diagnoses abstracted. Only 214 of 348 patients evaluated (61%) received an ASD diagnosis. Thus, concerns about autism are not confirmed by an ASD diagnosis in a significant number of children. © The Author(s) 2015.

NASA's Marshall Space Flight Center (MSFC), in conjunction with the United States Geological Survey (USGS) and aided by personnel from the Astromaterials Research and Exploration Science group at Johnson Space Center (ARES-JSC), is implementing a new data acquisition strategy to support the development and evaluation of lunar regolith simulants. The first analyses of lunar regolith samples by the simulant group were carried out in early 2008 on samples from Apollo 16 core 64001/64002. The results of these analyses are combined with data compiled from the literature to generate a reference composition and particle size distribution (PSD)) for lunar highlands regolith. In this paper we present the specifics of particle type composition and PSD for this reference composition. Furthermore. we use Figure-of-Merit (FoM) routines to measure the characteristics of a number of lunar regolith simulants against this reference composition. The lunar highlands regolith reference composition and the FoM results are presented to guide simulant producers and simulant users in their research and development processes.

Since the 1980s, infections due to Streptococcus pyogenes or group A streptococci (GAS) were marked by the increase in invasive infections and the emergence of clones which were resistant to macrolides. Those challenges led the French national reference center for streptococci to enhance the epidemiological survey and the characterization of GAS strains, in collaboration with the National Institute for Public Health Surveillance. Active surveillance is of major importance for implementation of therapeutic and prophylactic guidelines and for evaluation of future streptococcal vaccines. Copyright 2009 Elsevier Masson SAS.

Planner-Based Control of Advanced Life Support Systems

NASA Technical Reports Server (NTRS)

Muscettola, Nicola; Kortenkamp, David; Fry, Chuck; Bell, Scott

2005-01-01

The paper describes an approach to the integration of qualitative and quantitative modeling techniques for advanced life support (ALS) systems. Developing reliable control strategies that scale up to fully integrated life support systems requires augmenting quantitative models and control algorithms with the abstractions provided by qualitative, symbolic models and their associated high-level control strategies. This will allow for effective management of the combinatorics due to the integration of a large number of ALS subsystems. By focusing control actions at different levels of detail and reactivity we can use faster: simpler responses at the lowest level and predictive but complex responses at the higher levels of abstraction. In particular, methods from model-based planning and scheduling can provide effective resource management over long time periods. We describe reference implementation of an advanced control system using the IDEA control architecture developed at NASA Ames Research Center. IDEA uses planning/scheduling as the sole reasoning method for predictive and reactive closed loop control. We describe preliminary experiments in planner-based control of ALS carried out on an integrated ALS simulation developed at NASA Johnson Space Center.

To determine which features make a computer-based hearing health education intervention effective, easy to use, and enjoyable. The study examined which features of a multimedia self-administered computerized hearing loss prevention program, developed by the National Center for Rehabilitative Auditory Research (referred to as the NCRAR-HLPP), users liked and disliked, and the reasons why. A formative evaluation was conducted in which participants completed a questionnaire to assess knowledge and attitudes towards hearing and hearing loss prevention, used the NCRAR-HLPP, completed the questionnaire for a second time, and were interviewed to learn their opinions about the NCRAR-HLPP. Twenty-five male and four female Veterans recruited from the Portland VA Medical Center who were aged between 25 and 65 years. Participants reported that using the NCRAR-HLPP was a positive experience. Ease of use, multimedia content, personal relevance, and use of emotion were positive features of the program. The questionnaire showed increased knowledge and improved attitude scores following use of the program. This formative evaluation showed changes designed to target user preferences and improve user instructions will be made in future versions of the program.

German breast cancer screening is monitored by a large physical quality assurance program. This report refers to the first experiences of the Reference Center (RC) Muenster after three years of the technical quality control of digital and analog mammography units (MU). This paper also shows whether the presently used quality assurance (QA) method is able to ensure that the MUs in the screening program are functioning without any serious problems. RC Muenster supervises 95 units (May 2008). The daily, weekly and monthly quality assurance of these units is controlled by web-based QA software named "MammoConrol" and developed by RC Muenster. The annual QA for the units must be conducted in the form of an on-site inspection by medical physics experts of the RC and is scored by an objective ranking system. The results of these QA routines were evaluated and analyzed for this paper. During the period from 3/1/2006 to 5/31/2008, 8 % of the analog systems and 1 % of the digital systems exhibited problems in the daily QA. For 9 % of the analog MUs and 17 % of the digital MUs, failures appeared in the monthly QA. In the annual control, 86.7 % of the analog units exhibited slight problems and 13.3 % had serious problems. With respect to the digital units, 12 % were without any defects, 58 % had slight problems, 27 % had serious failures and 3 % had to be reported to the responsible authorities and were temporarily shut down. The special quality control requirements for German breast cancer screening, including annual on-site checks of the units, have shown in the last three years that QA with a high monitoring standard can be ensured for a large number of decentralized MUs. The currently used QA method sufficiently ensures that the screening program is technically safe. Further studies must show whether the density and focus of the QA measures must be reconfigured.

In the early 1970s Dr. John T. Mihalczo (team leader), J.J. Lynn, and J.R. Taylor performed experiments at the Oak Ridge Critical Experiments Facility (ORCEF) with highly enriched uranium (HEU) metal (called Oak Ridge Alloy or ORALLOY) in an attempt to recreate GODIVA I results with greater accuracy than those performed at Los Alamos National Laboratory in the 1950s (HEU-MET-FAST-001). The purpose of the Oak Ridge ORALLOY Sphere (ORSphere) experiments was to estimate the unreflected and unmoderated critical mass of an idealized sphere of uranium metal corrected to a density, purity, and enrichment such that it could be compared withmore » the GODIVA I experiments. “The very accurate description of this sphere, as assembled, establishes it as an ideal benchmark for calculational methods and cross-section data files” (Reference 1). While performing the ORSphere experiments care was taken to accurately document component dimensions (±0.0001 inches), masses (±0.01 g), and material data. The experiment was also set up to minimize the amount of structural material in the sphere proximity. Two, correlated spheres were evaluated and judged to be acceptable as criticality benchmark experiments. This evaluation is given in HEU-MET-FAST-100. The second, smaller sphere was used for additional reactor physics measurements. Worth measurements (Reference 1, 2, 3 and 4), the delayed neutron fraction (Reference 3, 4 and 5) and surface material worth coefficient (Reference 1 and 2) are all measured and judged to be acceptable as benchmark data.

How Cognitive Load Influences Speakers' Choice of Referring Expressions.

PubMed

Vogels, Jorrig; Krahmer, Emiel; Maes, Alfons

2015-08-01

We report on two experiments investigating the effect of an increased cognitive load for speakers on the choice of referring expressions. Speakers produced story continuations to addressees, in which they referred to characters that were either salient or non-salient in the discourse. In Experiment 1, referents that were salient for the speaker were non-salient for the addressee, and vice versa. In Experiment 2, all discourse information was shared between speaker and addressee. Cognitive load was manipulated by the presence or absence of a secondary task for the speaker. The results show that speakers under load are more likely to produce pronouns, at least when referring to less salient referents. We take this finding as evidence that speakers under load have more difficulties taking discourse salience into account, resulting in the use of expressions that are more economical for themselves. © 2014 Cognitive Science Society, Inc.

High Rate of Alternative Diagnoses in Patients Referred for Presumed Clostridium difficile Infection

2015-01-01

Goals We evaluated a cohort of patients referred to our center for presumed recurrent Clostridium difficile infection (CDI) to determine final diagnoses and outcomes. Background As rates of CDI have increased, more patients are diagnosed with recurrent CDI and other sequelae of the infection. Distinguishing symptomatic patients with CDI from those who are colonized with an alternative etiology of diarrheal symptoms may be challenging. Methods We performed a retrospective review of 117 patients referred to our center for recurrent CDI between January 2013 and June 2014. Data collected included demographics, referring provider, previous anti-CDI treatment, and significant medical conditions. Additionally we gathered data on atypical features of CDI and investigations obtained to investigate etiology of symptoms. Outcomes included rates of alternative diagnoses and the accuracy of CDI diagnosis by referral source. Results The mean age was 61 years and 70% were female. 29 patients (25%) were determined to have a non-CDI diagnosis. Most common alternative diagnoses included irritable bowel syndrome (18 patients: 62%) and inflammatory bowel disease (3:10 %). Age was inversely correlated with rate of non-CDI diagnosis (p=0.016). Of the remaining 88 (75%) patients with a confirmed diagnosis of CDI, 25 (28%) received medical therapy alone and 63 (72%) underwent fecal microbiota transplantation (FMT). Conclusion Among patients referred to our center for recurrent CDI, a considerable percentage did not have CDI, but rather an alternative diagnosis, most commonly IBS. The rate of alternative diagnosis correlated inversely with age. Providers should consider other etiologies of diarrhea in patients presenting with features atypical of recurrent CDI. PMID:26565971

Objective: to determine the prevalence of restless legs syndrome (RLS) in a cohort of patients with demyelinating neuropathies. Methods: Patients were retrospectively recruited from our cohort of different forms of demyelinating neuropathies, including chronic inflammatory demyelinating neuropathy (CIDP), Charcot-Marie-Tooth 1A (CMT1A), and hereditary neuropathy with liability to pressure palsies (HNPP) referred to our Department of Neurology in a 10-year period. The validated 4-item RLS questionnaire was used for diagnosis of RLS. All patients with RLS who fulfilled criteria underwent a suggested immobilization test to confirm the diagnosis. A group of outpatients referred to the sleep disorders unit and data from published literature were used as controls. Results: Prevalence of RLS in demyelinating neuropathy group was higher than prevalence observed in control population (p = 0.0142) or in the literature data (p = 0.0007). In particular, in comparison with both control population and literature data, prevalence of RLS was higher in CIDP group (p = 0.0266 and p = 0.0063, respectively) and in CMT1A group (p = 0.0312 and p = 0.0105, respectively), but not in HNPP (p = 1.000 and p = 0.9320, respectively). Conclusions: our study confirms a high prevalence of RLS in inflammatory neuropathies as CIDP and, among inherited neuropathies, in CMT1A but not in HNPP. Considering that this is only a small cohort from a single-center retrospective experience, the link between RLS and neuropathy remains uncertain, and larger multicenter studies are probably needed to clarify the real meaning of the association between RLS and neuropathy.

Telepsychiatry with child welfare families referred to a family service agency.

PubMed

Keilman, Peggy

2005-02-01

A telepsychology and telepsychiatry service, using ISDN interactive video H.320, providing psychological consultations for the Family Resource Center in Farmington, New Mexico, was evaluated. During the first year of service, 56 individuals participated including University of New Mexico staff, Family Resource Center staff and clients. Consultations involved children from families referred by the Children, Youth and Family Department (CYFD) in New Mexico. Telemedicine was used in some child abuse cases. This study investigated whether the quality and acceptance of telemedicine consultations were comparable to face-to-face interactions in a group referred by a state child welfare agency. Participants received formal written consultation reports after the video conferencing sessions, which included a number of recommendations. Participants were asked to complete an anonymous questionnaire to rate various aspects of videoconferencing. The participants rated the university staff as involved, enjoyed the Family Resource Center staff's presence, felt the procedure was useful for evaluation purposes, found the format allowed for discussions of problems, and felt that the format was useful when compared to face-to-face consultations. The participants also said they had followed up on many of the recommendations. Videoconferencing appears to be a viable approach for providing consultation for families referred by a state child welfare agency. Several participants rated the session as both educational and consultative compared to simply therapeutic.

Nontuberculous Mycobacteria Isolates at a Cancer Center: A 5-year Experience at H. Lee Moffitt Cancer Center in Tampa, Florida

Abstract Background Nontuberculous Mycobacteriae (NTM) are widely distributed in natural environments and are known to cause human diseases distinct from tuberculous mycobacteria. NTM caused diseases may lead to significant morbidity and mortality, particularly in immunocompromised hosts such as cancer patients. We present here a 5-year experience of NTM isolates at the Moffitt Cancer Center and research institute in Tampa, Florida. Methods We conducted a single center, retrospective study of patients with NTM from January 2011 to February 2016. Records were searched to identify patients with NTM. Specimens included bronchial lavage, swabs, blood, body fluids and biopsy or excised surgical specimens. Basic demographics of patients, clinical attributes, presentation and sites from which the NTM were isolated and associated neoplastic pathologies were evaluated for each NTM type and compared. Results There were a total of 208 isolates of NTM during the 5-year study period. 86/208 (41%) of the isolates were Mycobacterium avium complex (MAC). Mycobacterium abscessus, gordonae and fortuitum accounted for 26%, 11% and 6% of the top four isolates respectively. There was no significant difference in types of NTM isolated based on the type of underlying neoplasm. Over half of the cases were from the respiratory tract, majority with lung nodule referred to rule out cancer. Skin/wound isolates accounted for 13% (majority from breast lesions) and blood/serologic diagnosis accounted for 7 % of the isolates. Average age of patients was 68 ± 11 years, 92% were US born and over 70% had smoking history. Conclusion NTM isolated in a referral cancer center setting are likely to be from the work up of PET positive pulmonary nodules and the majority isolates were MAC, followed closely by M. abscessus. With high level of resistance and few therapeutic options, the rise of M. abscessus pulmonary diseases is cause for concern. Even though the respiratory tract was the most common site of NTM isolation, we did’nt find association between types of NTM and a given neoplasm. Our finding may have been confounded by referral pattern to our center and the retrospective design. Future studies that lead to improved testing and scoring algorithms for NTM could reduce the rate of surgical excision of pulmonary nodules. Disclosures All authors: No reported disclosures.

We evaluated the profile of patients referred to the Fiocruz Outpatient Clinic, a reference center for the diagnosis and treatment of leprosy in Rio de Janeiro, RJ, and analyzed the origins and outcomes of these referrals. This is an observational retrospective study based on information collected from the Leprosy Laboratory database at Fiocruz, Rio de Janeiro, RJ, Brazil. A total of 1,845 suspected leprosy cases examined at the reference center between 2010 and 2014 were included. The originating health service referrals and diagnostic outcomes were analyzed as well as the clinical and epidemiological data of patients diagnosed with leprosy. Our data show that the profile of the patients treated at the Clinic has changed in recent years. There was an increase in both the proportion of patients with other skin diseases and those who had visited only one health service prior to our Clinic. Among the total 1,845 cases analyzed, the outcomes of 1,380 were linked to other diseases and, in 74% of these cases, a biopsy was not necessary to reach a diagnostic conclusion. A decrease in new leprosy case detection among our patients was also observed. Yet, among the leprosy patients, 40% had some degree of disability at diagnosis. The results of the present study demonstrated the importance of referral centers in support of basic health services within the decentralization strategy. But, the success of the program depends on the advent of new developmental tools to augment diagnostic accuracy for leprosy. However, it should be emphasized that for new diagnostic methods to be developed, a greater commitment on the part of the health care system regarding research is urgently needed.

Gravity influences the visual representation of object tilt in parietal cortex.

Rosenberg, Ari; Angelaki, Dora E

2014-10-22

Sensory systems encode the environment in egocentric (e.g., eye, head, or body) reference frames, creating inherently unstable representations that shift and rotate as we move. However, it is widely speculated that the brain transforms these signals into an allocentric, gravity-centered representation of the world that is stable and independent of the observer's spatial pose. Where and how this representation may be achieved is currently unknown. Here we demonstrate that a subpopulation of neurons in the macaque caudal intraparietal area (CIP) visually encodes object tilt in nonegocentric coordinates defined relative to the gravitational vector. Neuronal responses to the tilt of a visually presented planar surface were measured with the monkey in different spatial orientations (upright and rolled left/right ear down) and then compared. This revealed a continuum of representations in which planar tilt was encoded in a gravity-centered reference frame in approximately one-tenth of the comparisons, intermediate reference frames ranging between gravity-centered and egocentric in approximately two-tenths of the comparisons, and in an egocentric reference frame in less than half of the comparisons. Altogether, almost half of the comparisons revealed a shift in the preferred tilt and/or a gain change consistent with encoding object orientation in nonegocentric coordinates. Through neural network modeling, we further show that a purely gravity-centered representation of object tilt can be achieved directly from the population activity of CIP-like units. These results suggest that area CIP may play a key role in creating a stable, allocentric representation of the environment defined relative to an "earth-vertical" direction.

Compilation of Published Estimates of Annual Geocenter Motions Using Space Geodesy

NASA Technical Reports Server (NTRS)

Elosegui, P.

2005-01-01

The definition of the term "geocenter motion" depends on the adopted origin of the reference frame. Common reference frames used in Space Geodesy include: the center of mass of the whole Earth (CM), the center of mass of the Solid Earth without mass load (CE), and the center of figure of the outer surface of the Solid Earth (CF). There are two established definitions of the term geocenter: one, the vector offset of CF relative to CM and, two, the reverse, the vector offset of CM relative to CF. Obviously, their amplitude is the same and their phase differs by 180 deg. Following Dong et al. [2003], we label the first X(sub CF, sup CM) and the second X(sup CF, sup CM) (i.e., the superscript represents the frame, the subscript represents any point in the frame).

Considering the absence of standards for culture collections and more specifically for biological resource centers in the world, in addition to the absence of certified biological material in Brazil, this study aimed to evaluate a Fungal Collection from Fiocruz, as a producer of certified reference material and as Biological Resource Center (BRC). For this evaluation, a checklist based on the requirements of ABNT ISO GUIA34:2012 correlated with the ABNT NBR ISO/IEC17025:2005, was designed and applied. Complementing the implementation of the checklist, an internal audit was performed. An evaluation of this Collection as a BRC was also conducted following the requirements of the NIT-DICLA-061, the Brazilian internal standard from Inmetro, based on ABNT NBR ISO/IEC 17025:2005, ABNT ISO GUIA 34:2012 and OECD Best Practice Guidelines for BRCs. This was the first time that the NIT DICLA-061 was applied in a culture collection during an internal audit. The assessments enabled the proposal for the adequacy of this Collection to assure the implementation of the management system for their future accreditation by Inmetro as a certified reference material producer as well as its future accreditation as a Biological Resource Center according to the NIT-DICLA-061.

Understanding Patient Barriers to Kidney Transplant Evaluation

PubMed Central

Dageforde, Leigh Anne; Box, Amanda; Feurer, Irene D.; Cavanaugh, Kerri L.

2015-01-01

Background Some patients referred for kidney transplant evaluation fail to attend the visit. Our goal was to compare demographic, socioeconomic, and psychological factors between evaluation visit attendees and absentees. Methods A convenience sample of patients referred and scheduled for kidney transplant evaluation at a single center from November 2012 to December 2013 participated in a phone survey reporting socioeconomic, demographic and clinical characteristics; health literacy; and perceived knowledge and concerns about transplantation. Absentees were matched by race with attendees. Analyses of differences between groups were performed with Chi-square, Fisher’s exact test, and t-tests. Multivariable logistic regression adjusted for relevant demographic characteristics. Results 104 adults participated (61% male, 46% Caucasian, 52±12 years). Financial concerns were the most prevalent (67.3% affording medication, 64.1% affording operation). Prior evaluation at a different transplant center (p=0.029) and being on dialysis (p=0.008) were significantly associated with absence. Attendance was associated with concerns about finding a living donor (p=0.038) and higher perceived general knowledge about transplantation (p ≤0.001). No differences were appreciated in demographic, socioeconomic or health literacy factors between groups. Conclusions Both attendee and absentee patients were most concerned with the financial burden of kidney transplantation. While concerns and perceived knowledge are important correlates of behavior, other considerations such as psychological factors and prior medical experiences may influence patients’ ability to complete the kidney transplant evaluation process. Although this pilot study was conducted in a small sample and has limited generalizability, our findings can guide future research. PMID:25606794

to determine the prevalence of restless legs syndrome (RLS) in a cohort of patients with demyelinating neuropathies. Patients were retrospectively recruited from our cohort of different forms of demyelinating neuropathies, including chronic inflammatory demyelinating neuropathy (CIDP), Charcot-Marie-Tooth 1A (CMT1A), and hereditary neuropathy with liability to pressure palsies (HNPP) referred to our Department of Neurology in a 10-year period. The validated 4-item RLS questionnaire was used for diagnosis of RLS. All patients with RLS who fulfilled criteria underwent a suggested immobilization test to confirm the diagnosis. A group of outpatients referred to the sleep disorders unit and data from published literature were used as controls. Prevalence of RLS in demyelinating neuropathy group was higher than prevalence observed in control population (p = 0.0142) or in the literature data (p = 0.0007). In particular, in comparison with both control population and literature data, prevalence of RLS was higher in CIDP group (p = 0.0266 and p = 0.0063, respectively) and in CMT1A group (p = 0.0312 and p = 0.0105, respectively), but not in HNPP (p = 1.000 and p = 0.9320, respectively). our study confirms a high prevalence of RLS in inflammatory neuropathies as CIDP and, among inherited neuropathies, in CMT1A but not in HNPP. Considering that this is only a small cohort from a single-center retrospective experience, the link between RLS and neuropathy remains uncertain, and larger multicenter studies are probably needed to clarify the real meaning of the association between RLS and neuropathy.

ASSESSING REFERRALS AND IMPROVING INFORMATION AVAILABILITY FOR CONSULTATIONS IN AN ACADEMIC ENDOCRINOLOGY CLINIC.

2017-02-01

Outpatient specialty consultations rely on the timeliness and completeness of referral information to facilitate a valuable patient-specialist interaction. This project aimed to increase essential diagnostic information availability at the initial consultation for patients referred for common endocrine conditions frequently lacking such data-diabetes mellitus, thyroid nodule, thyrotoxicosis, and hypercalcemia. At an endocrinology clinic at an academic medical center in rural New England, providers see several thousand new patients annually, the majority of whom are referred by providers external to the clinic's healthcare system. Through consensus, endocrinology clinic providers agreed on the two or three data elements essential for a meaningful initial consultation for each. A quality improvement team employed a planned series of interventions based on previously published methods and an innovative approach: dissemination of a referral guideline, an assessment of referral adequacy in the endocrinology clinic workflow, coupled with focused requests for missing items, and a pre-visit lab appointment. Between April 2015 and March 2016, 762 referrals were reviewed. At baseline for the four conditions, referrals contained all essential elements only 27.5% (22 of 80) of the time. Over a 7-month period, the team implemented the interventions, with subsequent referrals containing all essential elements increasing to 75.5% (P<.0001), largely attributable to the pre-visit lab appointment. Incoming referrals that lack essential information are a significant problem in specialty care and may adversely affect patient experience, provider satisfaction, and clinic efficiency. Improvement may require innovative approaches, such as the potentially transferable and generalizable ones employed here.

2014-01-01

The University of New England's Center for Excellence in the Neurosciences has developed a successful and growing K-12 outreach program that incorporates undergraduate and graduate/professional students. The program has several goals, including raising awareness about fundamental issues in neuroscience, supplementing science education in area schools and enhancing undergraduate and graduate/professional students' academic knowledge and skill set. The outreach curriculum is centered on core neuroscience themes including: Brain Safety, Neuroanatomy, Drugs of Abuse and Addiction, Neurological and Psychiatric Disorders, and Cognition and Brain Function. For each theme, lesson plans were developed based upon interactive, small-group activities. Additionally, we've organized our themes in a "Grow-up, Grow-out" approach. Grow-up refers to returning to a common theme, increasing in complexity as we revisit students from early elementary through high school. Grow-out refers to integrating other scientific fields into our lessons, such as the chemistry of addiction, the physics of brain injury and neuronal imaging. One of the more successful components of our program is our innovative team-based model of curriculum design. By creating a team of undergraduate, graduate/professional students and faculty, we create a unique multi-level mentoring opportunity that appears to be successful in enhancing undergraduate students' skills and knowledge. Preliminary assessments suggest that undergraduates believe they are enhancing their content knowledge and professional skills through our program. Additionally, we're having a significant, short-term impact on K-12 interest in science. Overall, our program appears to be enhancing the academic experience of our undergraduates and exciting K-12 students about the brain and science in general.

Novel Pulse Oximetry Sonifications for Neonatal Oxygen Saturation Monitoring: A Laboratory Study.

PubMed

Hinckfuss, Kelly; Sanderson, Penelope; Loeb, Robert G; Liley, Helen G; Liu, David

2016-03-01

We aimed to test whether the use of novel pulse oximetry sounds (sonifications) better informs listeners when a neonate's oxygen saturation (SpO2) deviates from the recommended range. Variable-pitch pulse oximeters do not accurately inform clinicians via sound alone when SpO2 is outside the target range of 90% to 95% for neonates on supplemental oxygen. Risk of blindness, organ damage, and death increase if SpO2 remains outside the target range. A more informative sonification may improve clinicians' ability to maintain the target range. In two desktop experiments, nonclinicians' ability to detect SpO2 range and direction of change was tested with novel versus conventional sonifications of simulated patient data. In Experiment 1, a "shoulder" sonification used larger pitch differences between adjacent saturation percentages for SpO2 values outside the target range. In Experiment 2, a "beacon" sonification used equal-appearing pitch differences, but when SpO2 was outside the target range, a fixed-pitch reference tone from the center of the target SpO2 range preceded every fourth pulse tone. The beacon sonification improved range identification accuracy over the control display (85% vs. 60%; p < .001), but the shoulder sonification did not (55% vs. 52%). The beacon provided a distinct auditory alert and reference that significantly improved nonclinical participants' ability to identify SpO2 range. Adding a beacon to the variable-pitch pulse oximeter sound may help clinicians identify when, and by how much, a neonate's SpO2 deviates from the target range, particularly during patient transport situations when auditory information becomes essential. © 2015, Human Factors and Ergonomics Society.

Testing the causal theory of reference.

PubMed

Domaneschi, Filippo; Vignolo, Massimiliano; Di Paola, Simona

2017-04-01

Theories of reference are a crucial research topic in analytic philosophy. Since the publication of Kripke's Naming and Necessity, most philosophers have endorsed the causal/historical theory of reference. The goal of this paper is twofold: (i) to discuss a method for testing experimentally the causal theory of reference for proper names by investigating linguistic usage and (ii) to present the results from two experiments conducted with that method. Data collected in our experiments confirm the causal theory of reference for people proper names and for geographical proper names. A secondary but interesting result is that the semantic domain affects reference assignment: while with people proper names speakers tend to assign the semantic reference, with geographical proper names they are prompted to assign the speaker's reference.

At an academic health science center, librarians identified problems, weaknesses, and strengths in reference services. The on-call reference schedule was discontinued and a question flowchart was developed for circulation staff. Only research questions were referred to librarians, who would respond if available. Circulation staff perceived the unscheduled, voluntary model was not working well for the patrons or the staff. After two months, the schedule was reinstated with a hybrid version of the previous on-call format. In the process of changing the service model, the library staff also underwent a cultural change.

Exploring infertile women's experiences about sexual life: A qualitative study

PubMed Central

Kohan, Shahnaz; Ghasemi, Zahra; Beigi, Marjan

2015-01-01

Background: Infertility is a serious problem in a couple's life that affects their marriage relationships. So, dissatisfaction with sexual function resulting from interpersonal problems is common among these couples. This qualitative study aimed to explore the experiences of infertile women in their sexual life. Materials and Methods: This is a qualitative study with a phenomenological approach. The participants were 20 infertile women referring to the health care centers and infertility clinics of Isfahan and were selected through purposive sampling. Data were collected by tape recording of deep interviews and analyzed by Colaizzi's method. Results: Analysis of the participants’ experiences led to five main concepts: “Disturbed in femininity-body image,” “discouragement of sexual relations,” “sacrifice of sexual pleasure for the sake of getting pregnant,” “confusion in sexual relation during infertility treatment,” and “striving to protect their marriage.” Conclusions: Findings revealed that infertility affects women's different aspects of sexual life, especially disturbance in femininity-body image and sexual reluctance. With regard to women's willingness to protect their matrimonial life and prevent sexual trauma as a destroying factor for their family's mental health, it seems sexual counseling is necessary for infertile couples.

Development of a Closed-Loop Strap Down Attitude System for an Ultrahigh Altitude Flight Experiment

NASA Technical Reports Server (NTRS)

Whitmore, Stephen A.; Fife, Mike; Brashear, Logan

1997-01-01

A low-cost attitude system has been developed for an ultrahigh altitude flight experiment. The experiment uses a remotely piloted sailplane, with the wings modified for flight at altitudes greater than 100,000 ft. Mission requirements deem it necessary to measure the aircraft pitch and bank angles with accuracy better than 1.0 deg and heading with accuracy better than 5.0 deg. Vehicle cost restrictions and gross weight limits make installing a commercial inertial navigation system unfeasible. Instead, a low-cost attitude system was developed using strap down components. Monte Carlo analyses verified that two vector measurements, magnetic field and velocity, are required to completely stabilize the error equations. In the estimating algorithm, body-axis observations of the airspeed vector and the magnetic field are compared against the inertial velocity vector and a magnetic-field reference model. Residuals are fed back to stabilize integration of rate gyros. The effectiveness of the estimating algorithm was demonstrated using data from the NASA Dryden Flight Research Center Systems Research Aircraft (SRA) flight tests. The algorithm was applied with good results to a maximum 10' pitch and bank angles. Effects of wind shears were evaluated and, for most cases, can be safely ignored.

DNA relatedness experiments were performed with 38 clinical isolates and 13 reference strains of coryneform taxa exhibiting a lipid requirement for optimal growth. Forty-five of these strains split into five genomic groups at the species level, whereas six other strains remained unclustered. Genomospecies II fits Corynebacterium accolens, but the other genomospecies were not genetically related to any of the defined Corynebacterium species. Phylogenetic analyses of genes coding for small-subunit rRNA sequences revealed that two genomospecies (I and III) and C. accolens form a tight cluster within the robust branch that groups all Corynebacterium species presently sequenced. Reference strains of biotypes C-1, C-2, and C-3 of "Corynebacterium pseudogenitalium" were found to fall into genomospecies I, as well as "Corynebacterium tuberculostearicum," Centers for Disease Control and Prevention (CDC) coryneform group G-1, and CDC coryneform group G-2 reference strains. Biochemical tests allowed differentiation between genomospecies except between genomospecies IV and V and between six unclustered strains and genomospecies I. We propose a new classification for these lipid-requiring diphtheroids within the genus Corynebacterium with the delineation of some CDC coryneform group G-1 strains (genomospecies III) as a new species for which the name Corynebacterium macginleyi is proposed. The type strain is strain JCL-2 (CIP 104099), isolated from a human corneal ulcer.

Compendium of Information for Interpreting the Microgravity Environment of the Orbiter Spacecraft

NASA Technical Reports Server (NTRS)

DeLombard, Richard

1996-01-01

Science experiments are routinely conducted on the NASA shuttle orbiter vehicles. Primarily, these experiments are operated on such missions to take advantage of the microgravity (low-level acceleration) environment conditions during on-orbit operations. Supporting accelerometer instruments are operated with the experiments to measure the microgravity acceleration environment in which the science experiments were operated. Tne Principal Investigator Microgravity Services (PIMS) Project at NASA Lewis Research Center interprets these microgravity acceleration data and prepares mission summary reports to aid the principal investigators of the scientific experiments in understanding the microgravity environment. Much of the information about the orbiter vehicle and the microgravity environment remains the same for each mission. Rather than repeat that information in each mission summary report, reference information is presented in this report to assist users in understanding the microgravity-acceleration data. The characteristics of the microgravity acceleration environment are first presented. The methods of measurement and common instruments used on orbiter missions are described. The coordinate systems utilized in the orbiter and accelerometers are described. Some of the orbiter attitudes utilized in microgravity related missions are illustrated. Methods of data processing are described and illustrated. The interpretation of the microgravity acceleration data is included with an explanation of common disturbance sources. Instructions to access some of the acceleration data and a description of the orbiter thrusters are explained in the appendixes. A microgravity environment bibliography is also included.

Characteristics of the transmission loss apparatus at NASA Langley Research Center

NASA Technical Reports Server (NTRS)

Grosveld, F. W.

1983-01-01

A description of the Transmission Loss Apparatus at NASA Langley Research Center, which is specifically designed to accommodate general aviation type aircraft structures, is presented. The measurement methodology, referred to as the Plate Reference Method, is discussed and compared with the classical method as described in the Standard of the American Society for Testing and Materials. This measurement procedure enables reliable and accurate noise transmission loss measurements down to the 50 Hz one-third octave band. The transmission loss characteristics of add-on acoustical treatments, applied to the basic structure, can be established by inclusion of appropriate absorption corrections for the treatment.

Parents who hit and scream: interactive effects of verbal and severe physical aggression on clinic-referred adolescents' adjustment.

2014-05-01

The goals of this study were first, to delineate the co-occurrence of parental severe physical aggression and verbal aggression toward clinic-referred adolescents, and second, to examine the interactive effects of parental severe physical aggression and verbal aggression on adolescent externalizing and internalizing behavior problems. This research involved 239 referrals of 11- to 18-year-old youth and their dual-parent families to a non-profit, private community mental health center in a semi-rural Midwest community. Multiple informants (i.e., adolescents and mothers) were used to assess parental aggression and adolescent behavior problems. More than half of clinic-referred adolescents (51%) experienced severe physical aggression and/or high verbal aggression from one or both parents. A pattern of interactive effects of mother-to-adolescent severe physical aggression and verbal aggression on adolescent behavior problems emerged, indicating that when severe physical aggression was present, mother-to-adolescent verbal aggression was positively associated with greater adolescent behavior problems whereas when severe physical aggression was not present, the links between verbal aggression and behavior problems was no longer significant. No interactive effects were found for father-to-adolescent severe physical aggression and verbal aggression on adolescent adjustment; however, higher father-to-adolescent verbal aggression was consistently linked to behavior problems above and beyond the influence of severe physical aggression. The results of this study should promote the practice of routinely assessing clinic-referred adolescents and their parents about their experiences of verbal aggression in addition to severe physical aggression and other forms of abuse.

[Extrahepatic biliary atresia: diagnostic methods].

Cauduro, Sydney M

2003-01-01

To emphasize the importance of precocious diagnosis of extrahepatic biliary atresia and its direct relationship with the surgical re-establishment of the biliary flow before the second month of life. To discuss several complementary methods with the aim of selecting the ones that present better evidence, and avoiding delays in diagnosis and worse prognostic. Bibliographical researching regarding the period of 1985-2001, in Medline and MdConsult, using the following key words: neo-natal cholestasis; extrahepatic biliary atresia; neo-natal hepatitis. National and foreign articles were also elected based on the bibliography of consulted publications, and when necessary, for better understanding of the theme, opinions emitted in theses and textbooks were referred. The revision of the consulted bibliography led to the assumption that early diagnosis of EHBA and surgical treatment to reestablish the biliary flow up to 60 days of life are fundamental in order to achieve good results. Among several complementary methods of diagnosis, cholangiography by MR, US and the hepatic biopsy are the ones that provide the largest success indexes. The referring of patients bearers of EHBA to centers of references in Brazil, is still made tardily, probably due to lack of enlightenment of the doctors of primary attention, allied to bureaucratic and technological difficulties. The experience in England in relation to the "Yellow Alert" program, allowed that the number of children referred to surgical treatment before the 60 days of life increased significantly. Among the complementary methods, the MR cholangiography, ultrasonography and hepatic biopsy should be used, depending on the technological resources of the diagnosis units.

Peripersonal space as the space of the bodily self.

PubMed

Noel, Jean-Paul; Pfeiffer, Christian; Blanke, Olaf; Serino, Andrea

2015-11-01

Bodily self-consciousness (BSC) refers to experience of one's self as located within an owned body (self-identification) and as occupying a specific location in space (self-location). BSC can be altered through multisensory stimulation, as in the Full Body Illusion (FBI). If participants view a virtual body from a distance being stroked, while receiving synchronous tactile stroking on their physical body, they feel as if the virtual body were their own and they experience, subjectively, to drift toward the virtual body. Here we hypothesized that--while normally the experience of the body in space depends on the integration of multisensory body-related signals within a limited space surrounding the body (i.e. peripersonal space, PPS)--during the FBI the boundaries of PPS would shift toward the virtual body, that is, toward the position of experienced self-location. To test this hypothesis, we used synchronous visuo-tactile stroking to induce the FBI, as contrasted with a control condition of asynchronous stroking. Concurrently, we applied an audio-tactile interaction paradigm to estimate the boundaries of PPS. PPS was measured in front of and behind the participants' body as the distance where tactile information interacted with auditory stimuli looming in space toward the participant's physical body. We found that during synchronous stroking, i.e. when participants experienced the FBI, PPS boundaries extended in the front-space, toward the avatar, and concurrently shrunk in the back-space, as compared to the asynchronous stroking control condition, when FBI was induced. These findings support the view that during the FBI, PPS boundaries translate toward the virtual body, such that the PPS representation shifts from being centered at the location of the physical body to being now centered at the subjectively experienced location of the self.

To analyze the frequency, rationale and determinants of attending physicians requesting that their eligible patients not be approached for participation in a thromboprophylaxis trial. Research personnel in 67 centers prospectively documented eligible non-randomized patients due to physicians declining to allow their patients to be approached. In 67 centers, 3,764 patients were enrolled, but 1,460 eligible patients had no consent encounter. For 218 (14.9 %) of these, attending physicians requested that their patients not be approached. The most common reasons included a high risk of bleeding (31.2 %) related to fear of heparin bioaccumulation in renal failure, the presence of an epidural catheter, peri-operative status or other factors; specific preferences for thromboprophylaxis (12.4 %); morbid obesity (9.6 %); uncertain prognosis (6.4 %); general discomfort with research (3.7 %) and unclear reasons (17.0 %). Physicians were more likely to decline when approached by less experienced research personnel; considering those with[10 years of experience as the reference category, the odds ratios (OR) for physician refusals to personnel without trial experience was 10.47 [95 % confidence interval (CI) 2.19-50.02] and those with less than 10 years experience was 1.72 (95 % CI 0.61-4.84). Physicians in open rather than closed units were more likely to decline (OR 4.26; 95 % CI 1.27-14.34). Refusals decreased each year of enrollment compared to the pilot phase. Tracking, analyzing, interpreting and reporting the rates and reasons for physicians declining to allow their patients to be approached for enrollment provides insights into clinicians' concerns and attitudes to trials. This information can encourage physician communication and education, and potentially enhance efficient recruitment.

Marshall Space Flight Center has developed a facility in which closed loop control of Large Space Structures (LSS) can be demonstrated and verified. The main objective of the facility is to verify LSS control system techniques so that on orbit performance can be ensured. The facility consists of an LSS test article which is connected to a payload mounting system that provides control torque commands. It is attached to a base excitation system which will simulate disturbances most likely to occur for Orbiter and DOD payloads. A control computer will contain the calibration software, the reference system, the alignment procedures, the telemetry software, and the control algorithms. The total system will be suspended in such a fashion that LSS test article has the characteristics common to all LSS.

The development of STS payload environmental engineering standards

NASA Technical Reports Server (NTRS)

Bangs, W. F.

1982-01-01

The presently reported effort to provide a single set of standards for the design, analysis and testing of Space Transportation System (STS) payloads throughout the NASA organization must be viewed as essentially experimental, since the concept of incorporating the diverse opinions and experiences of several separate field research centers may in retrospect be judged too ambitious or perhaps even naive. While each STS payload may have unique characteristics, and the project should formulate its own criteria for environmental design, testing and evaluation, a reference source document providing coordinated standards is expected to minimize the duplication of effort and limit random divergence of practices among the various NASA payload programs. These standards would provide useful information to all potential STS users, and offer a degree of standardization to STS users outside the NASA organization.

The Spanish primary health care, gateway and pillar of the Health Care System has his resources increasingly constrained by current crisis. To know the opinion of users and professionals on two primary care centers which centralized in August 2011 and 2012 the attendance of seven primary care centers. Two questionnaires were designed: a telephone survey of a random sample of users and a self-completed questionnaire for health care professionals. The variables were scored on a scale of 1-10 (low to high). Cronbach's coefficient α>0,84. 1293 people responded (836 users and 357 professionals). Users rated, in 2011, the satisfaction with 6.7 points in August and 7.3 points the rest of the year (P<.001). And, in 2012, with 7.7 points in August and 8.1 points the rest of the year (P<.001). Health care professionals, rated their satisfaction with 6.8 points in 2011 and 7.3 points in 2012. The waiting time was the only variable best scores in August that the rest of the year. The perception of the solution given in consultation did not change. Satisfaction, marking, care and treatment were highest rated in the regular center than in the reference center (P<.001). The centralization of primary health care during periods of reduced demand could reduce costs while maintaining quality. The experience of centralizing primary care services during August was perceived as acceptable and improved over time. Users showed a slight, but significant, preference for their usual primary care center. Copyright © 2014 Sociedad Española de Médicos de Atención Primaria (SEMERGEN).

Ground-level falls: 9-year cumulative experience in a regionalized trauma system

PubMed Central

Cade, Angela; King, Brad; Berne, John; Fernandez, Luis; Norwood, Scott

2012-01-01

Ground-level falls (GLFs) are the leading cause of nonfatal hospitalized injuries in the US. We hypothesized that risk-adjusted mortality would not vary between levels of trauma center verification if regional triage functioned appropriately. Data were collected from our regional trauma registry for the years 2001 through 2009. A multilevel mixed-effects logistic regression model was developed to compare risk-adjusted mortality rates by trauma center level and by year. GLF patients numbered 8202 over 9 years with 2.1% mortality. Mean age was 74.5 years and mean probability of death was 0.021 (95% confidence interval [CI], 0.020–0.021). The level I center–treated patients had the highest probability of death (0.033) compared to levels II and III/IV patients (0.023 and 0.018, respectively; P < 0.001), with the highest mortality (6.0%, 3.1%, and 1.1% for levels I, II, and III/IV; P < 0.001). The adjusted odds ratio of mortality was lowest at the level I center (0.71; 95% CI, 0.56–0.91), while no difference existed between level II (1.17; 95% CI, 0.90–1.51) and level III/IV centers (1.22; 95% CI, 0.90–1.66). The 95% CIs for risk-adjusted mortality by year overlapped the 1.0 reference line for each year from 2002 to 2009. In conclusion, regional risk-adjusted mortality for GLF has varied little since 2002. More study is warranted to understand the lower risk-adjusted GLF mortality at the level I center for this growing patient population. PMID:22275774

Competition between multiple words for a referent in cross-situational word learning

PubMed Central

Benitez, Viridiana L.; Yurovsky, Daniel; Smith, Linda B.

2016-01-01

Three experiments investigated competition between word-object pairings in a cross-situational word-learning paradigm. Adults were presented with One-Word pairings, where a single word labeled a single object, and Two-Word pairings, where two words labeled a single object. In addition to measuring learning of these two pairing types, we measured competition between words that refer to the same object. When the word-object co-occurrences were presented intermixed in training (Experiment 1), we found evidence for direct competition between words that label the same referent. Separating the two words for an object in time eliminated any evidence for this competition (Experiment 2). Experiment 3 demonstrated that adding a linguistic cue to the second label for a referent led to different competition effects between adults who self-reported different language learning histories, suggesting both distinctiveness and language learning history affect competition. Finally, in all experiments, competition effects were unrelated to participants’ explicit judgments of learning, suggesting that competition reflects the operating characteristics of implicit learning processes. Together, these results demonstrate that the role of competition between overlapping associations in statistical word-referent learning depends on time, the distinctiveness of word-object pairings, and language learning history.

The interaction of working and reference memory was studied in rats on an eight-arm radial maze. In two experiments, rats were trained to perform working memory and reference memory tasks. On working memory trials, they were allowed to enter four randomly chosen arms for reward in a study phase and then had to choose the unentered arms for reward in a test phase. On reference memory trials, they had to learn to visit the same four arms on the maze on every trial for reward. Retention was tested on working memory trials in which the interval between the study and test phase was 15 s, 15 min, or 30 min. At each retention interval, tests were performed in which the correct WM arms were either congruent or incongruent with the correct RM arms. Both experiments showed that congruency interacted with retention interval, yielding more forgetting at 30 min on incongruent trials than on congruent trials. The effect of reference memory strength on the congruency effect was examined in Experiment 1, and the effect of associating different contexts with working and reference memory on the congruency effect was studied in Experiment 2.

Hospital-based outpatient departments traditionally charge higher prices for ambulatory procedures, compared with freestanding surgery centers. Under emerging reference-based benefit designs, insurers establish a contribution limit that they will pay, requiring the patient to pay the difference between that contribution limit and the actual price charged by the facility. The purpose of this study was to evaluate the impact of reference-based benefits on consumer choices, facility prices, employer spending, and surgical outcomes for orthopaedic procedures performed at ambulatory surgery centers. We obtained data on 3962 patients covered by the California Public Employees' Retirement System (CalPERS) who underwent arthroscopy of the knee or shoulder in the three years prior to the implementation of reference-based benefits in January 2012 and on 2505 patients covered by CalPERS who underwent arthroscopy in the two years after implementation. Control group data were obtained on 57,791 patients who underwent arthroscopy and were not subject to reference-based benefits. The impact of reference-based benefits on consumer choices between hospital-based and freestanding facilities, facility prices, employer spending, and surgical complications was assessed with use of difference-in-differences multivariable regressions to adjust for patient demographic characteristics, comorbidities, and geographic location. By the second year of the program, the shift to reference-based benefits was associated with an increase in the utilization of freestanding ambulatory surgery centers by 14.3 percentage points (95% confidence interval, 8.1 to 20.5 percentage points) for knee arthroscopy and by 9.9 percentage points (95% confidence interval, 3.2 to 16.7 percentage points) for shoulder arthroscopy and a corresponding decrease in the use of hospital-based facilities. The mean price paid by CalPERS fell by 17.6% (95% confidence interval, -24.9% to -9.6%) for knee procedures and by 17.0% (95% confidence interval, -29.3% to -2.5%) for shoulder procedures. The shift to reference-based benefits was not associated with a change in the rate of surgical complications. In the first two years after the implementation of reference-based benefits, CalPERS saved $2.3 million (13%) on these two orthopaedic procedures. Reference-based benefits increase consumer sensitivity to price differences between freestanding and hospital-based surgical facilities. This study shows that the implementation of reference-based benefits does not result in a significant increase in measured complication rates for those subject to reference-based benefits.
