Jeong, Geum-Hee

2008-01-01

A discriminant analysis was conducted to investigate how an essay, a mathematics/science type of essay, a college scholastic ability test, and grade point average affect acceptance to a pre-med course at a Korean medical school. Subjects included 122 and 385 applicants for, respectively, early and regular admission to a medical school in Korea. The early admission examination was conducted in October 2007, and the regular admission examination was conducted in January 2008. The analysis of early admission data revealed significant F values for the mathematics/science type of essay (51.64; Pgrade point average (10.66; P=0.0014). The analysis of regular admission data revealed the following F values: 28.81 (Pgrade point average, 27.47 (P<0.0001) for college scholastic ability test, 10.67 (P=0.0012) for the essay, and 216.74 (P<0.0001) for the mathematics/science type of essay. Since the mathematics/science type of essay had a strong effect on acceptance, an emphasis on this requirement and exclusion of other kinds of essays would be effective in subsequent entrance examinations for this premed course.

Non-monotonic Pre-fixed Points and Learning

Directory of Open Access Journals (Sweden)

Stefano Berardi

2013-08-01

Full Text Available We consider the problem of finding pre-fixed points of interactive realizers over arbitrary knowledge spaces, obtaining a relative recursive procedure. Knowledge spaces and interactive realizers are an abstract setting to represent learning processes, that can interpret non-constructive proofs. Atomic pieces of information of a knowledge space are stratified into levels, and evaluated into truth values depending on knowledge states. Realizers are then used to define operators that extend a given state by adding and possibly removing atoms: in a learning process states of knowledge change nonmonotonically. Existence of a pre-fixed point of a realizer is equivalent to the termination of the learning process with some state of knowledge which is free of patent contradictions and such that there is nothing to add. In this paper we generalize our previous results in the case of level 2 knowledge spaces and deterministic operators to the case of omega-level knowledge spaces and of non-deterministic operators.

Pre-grade academic project: Technicature in nuclear applications

International Nuclear Information System (INIS)

Daoud, Adrian; Garcia Blesa, Hernan M.; Lerner, Ana M.; Notari, Carla

2009-01-01

The increasing use of radiation and radioactive materials in the world today has created a demand of Specialized Nuclear Technicians. Both at the international level and locally in Argentina, such demand is expected to continue being significant for several years, and at present it already exceeds the offer of qualified personnel, which constitutes an interesting stimulus for graduates. For this reason, the Dan Beninson Nuclear Technology Institute has decided to accept the challenge of educating specialized technicians, and has thus designed a new pre-grade career: the Technicature in Nuclear Applications. The basis of this proposal is to design a three year high level specific training program in order to produce highly qualified technicians with a title issued by our Institute, offer the students a unique education with interesting working opportunities and required in all those areas that in one way or other are related to radiation and radioactive materials. No equivalent academic offer is in place today at university level. Due to the renaissance of nuclear activity and the subsequent increasing use of radioisotopes and radiation in technological applications as well as in energy generation, medical applications, agriculture, pharmacology, among others, it has become mandatory to train specialized human resources in this field. Having these goals in mind, our Institute has created this career, with the purpose of satisfying such request which will benefit the whole society. (author)

Method of producing a diesel fuel blend having a pre-determined flash-point and pre-determined increase in cetane number

Science.gov (United States)

Waller, Francis Joseph; Quinn, Robert

2004-07-06

The present invention relates to a method of producing a diesel fuel blend having a pre-determined flash-point and a pre-determined increase in cetane number over the stock diesel fuel. Upon establishing the desired flash-point and increase in cetane number, an amount of a first oxygenate with a flash-point less than the flash-point of the stock diesel fuel and a cetane number equal to or greater than the cetane number of the stock diesel fuel is added to the stock diesel fuel in an amount sufficient to achieve the pre-determined increase in cetane number. Thereafter, an amount of a second oxygenate with a flash-point equal to or greater than the flash-point of the stock diesel fuel and a cetane number greater than the cetane number of the stock diesel fuel is added to the stock diesel fuel in an amount sufficient to achieve the pre-determined increase in cetane number.

Society increasingly holds schools responsible for the effectiveness of health promotion activities, such as drug abuse prevention efforts funded through the federal Safe and Drug-Free Schools program. Consequently, school districts use student surveys as a method for assessing trends and evaluating effects of programs on behavior. Because cost and practical concerns often preclude consistent population-based school survey sampling, risk indicators can provide an essential tool in analyzing needs assessment and program evaluation data. In this paper, three risk measures associated with substance use were selected from among commonly used school surveys. These measures--truancy, grade point average, and recent sexual intercourse--were compared, using meta-analysis techniques, to assess the reliability of risk measures across different survey instruments, different communities, and different points in time. Truancy was judged superior, because of its strong predictive value, particularly among younger students, and because rates can be compared to school records to assess sampling validity over time.

Can pre-grade R be the stepping stone to social equality in South Africa

Directory of Open Access Journals (Sweden)

Janeli Kotze

2015-12-01

Full Text Available Investment in Early Childhood Development (ECD has the prospect of cultivating potential within individuals and can assist in bridging the social equity gap from a very young age. Over the past decade Grade R has been the strongest policy lever used by the Department of Basic Education to improve early learning. The National Development Plan calls for universal access to two years of early childhood development prior to entering Grade 1. This paper explores the merits of this proposal, given the specific South African context. More specifically, this analysis intents to bring new information to bear on three matters. The first relates to the demand-side and aims to identify participation trends among four and five year olds. The second objective is to consider the supply-side and aims to understand the policy space in which pre-Grade R will function, the quality and quantity of infrastructure already in place, and the expertise of ECD practitioners. The final question considers the implementation of a universally accessible pre-Grade R within a constrained system and the requirements to ensure that it will have a significant impact on those children most in need.

This report is a resource document characterizing the 64 fuel rods being irradiated at the Big Rock Point reactor as part of the Extended Burnup Demonstration being sponsored jointly by the US Department of Energy, Consumers Power Company, Exxon Nuclear Company, and General Public Utilities. The program entails extending the exposure of standard BWR fuel to a discharge average of 38,000 MWD/MTU to demonstrate the feasibility of operating fuel of standard design to levels significantly above current limits. The fabrication characteristics of the Big Rock Point EBD fuel are presented along with measurement of rod length, rod diameter, pellet stack height, and fuel rod withdrawal force taken at poolside at burnups up to 26,200 MWD/MTU. A review of the fuel examination data indicates no performance characteristics which might restrict the continued irradiation of the fuel

2013-01-01

To determine predictive validity of pre-admission scores of medical students, evaluate correlation between level of motivation and later on academic success in a medical college. Analytical study. Foundation University Medical College, Islamabad, from June to August 2011. A non-probability convenience sampling of students of 1st to final year MBBS classes was done after obtaining informed consent. These students filled out 'Strength of Motivation for Medical School' (SMMS) questionnaire. The data of pre-admission grades of these students along with academic success in college according to examination results in different years were collected. The correlation between the pre-admission grades and score of SMMS questionnaire with their academic success in medical college was found by applying Pearson co-efficient of correlation in order to determine the predictive validity. Only 46% students revealed strong motivation. A significant, moderate correlation was found between preadmission scores and academic success in 1st year modular examination (0.52) which became weaker in various professional examinations in higher classes. However, no significant correlation was observed between motivation and academic success of medical students in college. Selecting medical students by pre-admission scores or motivation level alone may not be desirable. A combination of measures of cognitive ability criteria (FSc/pre-admission test scores) and non-cognitive skills (personality traits) is recommended to be employed with the use of right tools for selection of students in medical schools.

2013-01-01

To retrospectively evaluate fatty degeneration (FD) of rotator cuff muscles on CTA using Goutallier's grading system and quantitative measurements with comparison between pre- and postoperative states. IRB approval was obtained for this study. Two radiologists independently reviewed pre- and postoperative CTAs of 43 patients (24 males and 19 females, mean age, 58.1 years) with 46 shoulders confirmed as full-thickness tears with random distribution. FD of supraspinatus, infraspinatus/teres minor, and subscapularis was assessed using Goutallier's system and by quantitative measurements of Hounsfield units (HUs) on sagittal images. Changes in FD grades and HUs were compared between pre- and postoperative CTAs and analyzed with respect to preoperative tear size and postoperative cuff integrity. The correlations between qualitative grades and quantitative measurements and their inter-observer reliabilities were also assessed. There was statistically significant correlation between FD grades and HU measurements of all muscles on pre- and postoperative CTA (p 0.05). The average dose-length product (DLP, mGy . cm) was 365.2 mGy . cm (range, 323.8-417.2 mGy . cm) and estimated average effective dose was 5.1 mSv. Goutallier grades correlated well with HUs of rotator cuff muscles. Reliability was excellent for both systems, except for FD grade of IST/TM muscles, which may be more reliably assessed using quantitative measurements. (orig.)

Passow, M. J.

2015-12-01

Programs to help pre-college students understand the importance of Sustainability can be found around the world. A key feature for many is the collaboration among educators, researchers, and business. Two examples will be described to indicate what is being done and goals for the future. "Educação para a Sustentabilidade" ("Education for Sustainability", http://sustentabilidade.colband.net.br/) developed at the Colegio Bandeirantes in Sao Paulo, Brazil, is a popular extracurricular offering at one of Brazil's top schools that empowers students to investigate major issues facing their country and the world. They recognized that merely knowing is insufficient, so they have created several efforts towards an "environmentally friendly, socially just, and economically viable" world. The Education Project for Sustainability Science interacts with students in various grade levels within the school, participates in sustainability initiatives in other parts of the nation, and communicates electronically with like-minded programs in other countries. A second example will spotlight the CHANGE Viewer (Climate and Health Analysis for Global Education Viewer, http://climatechangehumanhealth.org/), a visualization tool that uses NASA World Wind to explore climate science through socio-economic datasets. Collaboration among scientists, programmers, and classroom educators created a suite of activities available to teach about Food Security, Water Resources, Rising Sea Level, and other themes.

Grade pending: lessons for hospital quality reporting from the New York City restaurant sanitation inspection program.

Ryan, Andrew M; Detsky, Allan S

2015-02-01

Public quality reporting programs have been widely implemented in hospitals in an effort to improve quality and safety. One such program is Hospital Compare, Medicare's national quality reporting program for US hospitals. The New York City sanitary grade inspection program is a parallel effort for restaurants. The aims of Hospital Compare and the New York City sanitary inspection program are fundamentally similar: to address a common market failure resulting from consumers' lack of information on quality and safety. However, by displaying easily understandable information at the point of service, the New York City sanitary inspection program is better designed to encourage informed consumer decision making. We argue that this program holds important lessons for public quality reporting of US hospitals. © 2014 Society of Hospital Medicine.

In renal transplantation, serum soluble CD30 (sCD30) levels in graft recipients are associated with increased rejection and graft loss. We investigated whether pre-transplant sCD30 concentrations are predictive of the grade of rejection. Pre-transplant sera of 51 patients with tubulointerstitial rejection (TIR), 16 patients with vascular rejection (VR) and an age-matched control group of 41 patients with no rejection (NR) were analyzed for sCD30. The transplant biopsies were immunostained for C4d. The median sCD30 level was significantly elevated in the group with VR (248 Units (U)/mL, range: 92-802) when compared with TIR (103 U/mL, range: 36-309, psCD30 levels compared to NR. Based on C4d staining, a TH2 driven process, the median sCD30 levels were significantly raised in C4d+ patients compared with C4d- group (177 U/mL vs. 120 U/mL, psCD30 levels measured at time of transplantation correlate with the grade of rejection. High pre-transplant levels are associated with antibody-mediated rejection which carries a poorer prognosis. sCD30 could be another tool to assess immunological risk prior to transplantation and enable a patient centered approach to immunosuppression.

Objective: To compare the accuracy of MR imaging scores with MR perfusion imaging in pre-operative grading of intracranial gliomas. Methods: Thirty patients with intracranial gliomas (8 low-grade and 22 high-grade, according to WHO criteria) were examined with MR perfusion imaging pre-operatively. The lesions were evaluated by using an MR imaging score based on nine criteria. rCBV of the lesions were calculated by comparing the CBV of the lesion and that of contralateral normal white matter. The scores and ratios in high-grade and low-grade tumours were compared. Results: The MR imaging score of low grade (grades I and II) gliomas (0.67±0.29) were significantly lower than that of grades III (1.32 ± 0.47) (t=-3.48, P=0.003) and IV (1.56 ± 0.20) (t=-7.36, P=0.000) gliomas. There was no statistical difference when MR imaging scores of grades III and IV gliomas (t=-1.39, P=0.182) were compared. The maximum rCBV ratio of low grade (grades I and II) gliomas (2.38 ± 0.66 ) were significantly lower than that of grades III (5.81 ± 3.20) (t=-3.57, P=0.003) and IV (6.99 ± 2.47) (t=-5.09, P=0.001). There was no statistical difference when rCBV ratios of grades III and IV (t =-0.93, P=0.365) gliomas were compared. The accuracy of MR imaging scores in the noninvasive grading of untreated gliomas was all most the same as that of MR perfusion imaging (90.00% vs 89.29%). Conclusion: The MR imaging scores and MR perfusion imaging are two very useful tools in the evaluation of the histopathologic grade of cerebral gliomas. The overall accuracy in the noninvasive grading of gliomas may be imp roved if MR imaging scores and MR perfusion imaging are combined. (authors)

Grade inflation at a north american college of veterinary medicine: 1985-2006.

Science.gov (United States)

Rush, Bonnie R; Elmore, Ronnie G; Sanderson, Michael W

2009-01-01

Grade inflation, an upward shift in student grade-point averages without a similar rise in achievement, is considered pervasive by most experts in post-secondary education in the United States. Grade-point averages (GPAs) at US universities have increased by roughly 0.15 points per decade since the 1960s, with a 0.6-point increase since 1967. In medical education, grade inflation has been documented and is particularly evident in the clinical setting. The purpose of this study was to evaluate grade inflation over a 22-year period in a college of veterinary medicine. Academic records from 2,060 students who graduated from the College of Veterinary Medicine at Kansas State University between 1985 and 2006 were evaluated, including cumulative GPAs earned during pre-clinical professional coursework, during clinical rotations, and at graduation. Grade inflation was documented at a rate of approximately 0.2 points per decade at this college of veterinary medicine. The difference in mean final GPA between the minimum (1986) and maximum (2003) years of graduation was 0.47 points. Grade inflation was similar for didactic coursework (years 1-3) and clinical rotations (final year). Demographic shifts, student qualifications, and tuition do not appear to have contributed to grade inflation over time. A change in academic standards and student evaluation of teaching may have contributed to relaxed grading standards, and technology in the classroom may have led to higher (earned) grades as a result of improved student learning.

Our study examined the effects of Write Start, a classroom-embedded handwriting/writing program on handwriting and writing fluency for first grade students, co-taught by occupational therapists and teachers. Two first grade classrooms received the Write Start and two received standard handwriting instruction. This co-taught program included specific feedback during handwriting practice, small group activities, student self-evaluation, and peer supports. The students were evaluated on handwriting legibility, fluency, and written expression at baseline, immediately after the program, and 6 months later. When performance was compared between the two groups, the students in the Write Start program improved significantly more in legibility (d = .57) and fluency (d = .75) than students who received standard instruction. Gains in handwriting speed (d = .18), average legibility (d = .26), and written expression (d = .25) did not differ significantly between the two groups. A co-taught, inclusive handwriting/writing program can promote first grade students' achievement of lower case legibility and writing fluency.

2010-03-01

The aim of this study was to investigate the usefulness of the undergraduate grade point average in prediction of scientific production of research trainees during their fellowship and later in career. The study was performed in 1320 research trainees whose fellowships from the Croatian Ministry of Science, Education and Sports were terminated between 1999 and 2005. The data were analyzed using logistic regression. The results indicated that undergraduate grade point average was negatively associated with scientific productivity both during and after the fellowship termination. Other indicators, such as undergraduate scientific productivity exhibited much stronger positive association with scientific productivity later in career and should be given more weight in candidate selection process in science and research.

Emotional intelligence: an admission criterion alternative to cumulative grade point averages for prelicensure students.

Science.gov (United States)

Jones-Schenk, Jan; Harper, Mary G

2014-03-01

Predicting potential student success is of great interest to nursing educators and academic administrators alike. Cumulative grade point average (CGPA) has traditionally been used to screen nursing program candidates, but CGPA itself has shown to have no statistically significant predictive value and may in fact screen out individuals who possess social intelligence attributes that are essential for success in nursing practice. The purpose of this study is to determine if students whose emotional intelligence characteristics meet or exceed those of successful staff nurses are more likely to be successful in a baccalaureate nursing program. A descriptive, correlational design was used to compare the emotional intelligence attributes of 116 potential nursing students and 42 successful staff nurses using the Emotional Quotient Inventory (EQ-i). Nursing students who remained in the nursing program were found to have significantly higher levels of total emotional intelligence, interpersonal capacity, and stress tolerance. Students who dropped from the nursing program were not significantly different from successful staff nurses in terms of emotional intelligence. Emotional intelligence presents a compelling adjunct to current selection criteria for nursing students. However, the lack of research prevents widespread adoption of this criterion. This study suggests that students with higher levels of emotional intelligence, particularly intrapersonal capacity and stress tolerance, are more likely to be successful in a baccalaureate nursing program than students with lower levels. Further research is needed to determine the usefulness of EI as a predictor of student success in nursing programs. Copyright © 2013 Elsevier Ltd. All rights reserved.

2018-04-01

HIV pre-exposure prophylaxis has been proven to be an effective tool in HIV prevention. However, numerous barriers still exist in pre-exposure prophylaxis implementation. The framework of Intervention Mapping was used from August 2016 to October 2017 to describe the process of adoption, implementation, and maintenance of an HIV prevention program from 2012 through 2017 in Houston, Texas, that is nested within a county health system HIV clinic. Using the tasks outlined in the Intervention Mapping framework, potential program implementers were identified, outcomes and performance objectives established, matrices of change objectives created, and methods and practical applications formed. Results include the formation of three matrices that document program outcomes, change agents involved in the process, and the determinants needed to facilitate program adoption, implementation, and maintenance. Key features that facilitated successful program adoption and implementation were obtaining leadership buy-in, leveraging existing resources, systematic evaluation of operations, ongoing education for both clinical and nonclinical staff, and attention to emergent issues during launch. The utilization of Intervention Mapping to delineate the program planning steps can provide a model for pre-exposure prophylaxis implementation in other settings. Copyright © 2018.

2011-09-01

The effects of student-faculty interactions in higher education have received considerable empirical attention. However, there has been no empirical study that has examined the relation between student-faculty interaction and college grade point average. This is aimed at identifying the effect of nursing student-faculty interaction outside the classroom on students' semester college grade point average at a public university in Jordan. The research was cross-sectional study of the effect of student-faculty interaction outside the classroom on the students' semester college grade point average of participating juniors and seniors. Total interaction of the students was crucial as it is extremely significant (t = 16.2, df = 271, P ≤ 0.001) in relation to students' academic scores between those students who had ≥70 and those who had <70 academic scores. However, gender differences between students, and other variables were not significant either to affect students' academic scores or students' interaction. This study provides some evidence that student-faculty interactions outside classrooms are significantly associated with student's academically achievements. Copyright © 2011 Elsevier Ltd.

malnutrition is a common complication for cancer patients. The phase angle (PA), direct measurement of bioelectrical impedance analysis (BIA), has been considered a predictor of body cell mass and prognostic indicator. Cutoff points for phase angle (PA) associated with nutritional risk in cancer patients have not been determined yet. assess the possibility of determining the cutoff point for PA to identify nutritional risk in pre-radiotherapy cancer patients. sample group: Patients from both genders diagnosed with cancer and sent for ambulatory radiotherapy. body mass index (BMI), percentage of weight loss (% WL), mid-arm circumference (MAC), triceps skinfold thickness (TST), mid-arm muscle circumference (MAMC), mid-arm muscle area (MAMA), score and categorical assessment obtained using the Patient-Generated Subjective Global Assessment (PG-SGA) form, PA and standardized phase angle (SPA). Kappa coefficient was used to test the degree of agreement between the diagnoses of nutritional risk obtained from several different methods of nutritional assessment. Cutoff points for the PA through anthropometric indicators and PG-SGA were determined by using Receiver Operating Characteristic (ROC) curves, and patient survival was analyzed with the Cox regression method. the cutoff points with the greatest discriminatory power were those obtained from BMI (5.2) and the categorical assessment of PG-SGA (5.4). The diagnosis obtained using these cutoff points showed a significant association with risk of death for the patients in the sample group. we recommend using the cutoff point 5.2 for the PA as a criterion for identifying nutritional risk in pre-radiotherapy cancer patients.

The correlation between physical activity and grade point average for health science graduate students.

Science.gov (United States)

Gonzalez, Eugenia C; Hernandez, Erika C; Coltrane, Ambrosia K; Mancera, Jayme M

2014-01-01

Researchers have reported positive associations between physical activity and academic achievement. However, a common belief is that improving academic performance comes at the cost of reducing time for and resources spent on extracurricular activities that encourage physical activity. The purpose of this study was to examine the relationship between self-reported physical activity and grade point average (GPA) for health science graduate students. Graduate students in health science programs completed the International Physical Activity Questionnaire and reported their academic progress. Most participants (76%) reported moderate to vigorous physical activity levels that met or exceeded the recommended levels for adults. However, there was no significant correlation between GPA and level of physical activity. Negative findings for this study may be associated with the limited range of GPA scores for graduate students. Future studies need to consider more sensitive measures of cognitive function, as well as the impact of physical activity on occupational balance and health for graduate students in the health fields.

Bennett, Andrew Keith [WorleyParsons Calgary, Calgary, AB (Canada); Wong, Everett Clementi [Enbridge Pipelines Inc., Edmonton, AB (Canada)

2010-07-01

During the design phase of a pipeline project, large hydrostatic test programs are required to locate and secure water sources. Many companies complete hydrostatic test planning through high level desktop analysis, however this technique can result in important unplanned costs and schedule delays. The aim of this paper is to assess the cost benefits of pre-planning large hydrostatic test programs versus the costs of unplanned delays in the execution of hydrostatic testing. This comparison was based on the successful application of pre-planning of 57 mainline hydrostatic tests in the construction of the Line 4 Extension and Alberta Clipper Expansion oil pipelines by Enbridge Pipelines Inc. Results showed that costs of delays and uncertainty during construction far outweigh the costs of pre-planning. This study highlighted that pre-planning for large hydrostatic test programs should be carried out in the execution of large pipeline projects to ensure success.

: Laboratory quality programs rely on internal quality control and external quality assessment (EQA). EQA programs provide unknown specimens for the laboratory to test. The laboratory's result is compared with other (peer) laboratories performing the same test. EQA programs assign target values using a variety of methods statistical tools and performance assessment of 'pass' or 'fail' is made. EQA provider members of the international organization, external quality assurance in thrombosis and hemostasis, took part in a study to compare outcome of performance analysis using the same data set of laboratory results. Eleven EQA organizations using eight different analytical approaches participated. Data for a normal and prolonged activated partial thromboplastin time (aPTT) and a normal and reduced factor VIII (FVIII) from 218 laboratories were sent to the EQA providers who analyzed the data set using their method of evaluation for aPTT and FVIII, determining the performance for each laboratory record in the data set. Providers also summarized their statistical approach to assignment of target values and laboratory performance. Each laboratory record in the data set was graded pass/fail by all EQA providers for each of the four analytes. There was a lack of agreement of pass/fail grading among EQA programs. Discordance in the grading was 17.9 and 11% of normal and prolonged aPTT results, respectively, and 20.2 and 17.4% of normal and reduced FVIII results, respectively. All EQA programs in this study employed statistical methods compliant with the International Standardization Organization (ISO), ISO 13528, yet the evaluation of laboratory results for all four analytes showed remarkable grading discordance.

2015-01-01

We aimed to evaluate the diagnostic potential of dual-time-point imaging with positron emission tomography (PET) using O-(2-[ 18 F]fluoroethyl)-L-tyrosine ( 18 F-FET) for non-invasive grading of cerebral gliomas compared with a dynamic approach. Thirty-six patients with histologically confirmed cerebral gliomas (21 primary, 15 recurrent; 24 high-grade, 12 low-grade) underwent dynamic PET from 0 to 50 min post-injection (p.i.) of 18 F-FET, and additionally from 70 to 90 min p.i. Mean tumour-to-brain ratios (TBR mean ) of 18 F-FET uptake were determined in early (20-40 min p.i.) and late (70-90 min p.i.) examinations. Time-activity curves (TAC) of the tumours from 0 to 50 min after injection were assigned to different patterns. The diagnostic accuracy of changes of 18 F-FET uptake between early and late examinations for tumour grading was compared to that of curve pattern analysis from 0 to 50 min p.i. of 18 F-FET. The diagnostic accuracy of changes of the TBR mean of 18 F-FET PET uptake between early and late examinations for the identification of HGG was 81 % (sensitivity 83 %; specificity 75 %; cutoff - 8 %; p < 0.001), and 83 % for curve pattern analysis (sensitivity 88 %; specificity 75 %; p < 0.001). Dual-time-point imaging of 18 F-FET uptake in gliomas achieves diagnostic accuracy for tumour grading that is similar to the more time-consuming dynamic data acquisition protocol. (orig.)

Determination of uptake heterogeneity in pre-therapeutic FET-PET using textural features proved valuable for the (sub-)grading of high-grade glioma as well as prediction of tumor progression and patient survival, and showed improved performance compared to standard parameters such as TBR and tumor volume. Our results underscore the importance of intratumoral heterogeneity in the biology of high-grade glial cell tumors and may contribute to individual therapy planning in the future, although they must be confirmed in prospective studies before incorporation into clinical routine.

Determination of Safety Performance Grade of NPP Using Integrated Safety Performance Assessment (ISPA) Program

International Nuclear Information System (INIS)

Chung, Dae Wook

2011-01-01

Since the beginning of 2000, the safety regulation of nuclear power plant (NPP) has been challenged to be conducted more reasonable, effective and efficient way using risk and performance information. In the United States, USNRC established Reactor Oversight Process (ROP) in 2000 for improving the effectiveness of safety regulation of operating NPPs. The main idea of ROP is to classify the NPPs into 5 categories based on the results of safety performance assessment and to conduct graded regulatory programs according to categorization, which might be interpreted as 'Graded Regulation'. However, the classification of safety performance categories is highly comprehensive and sensitive process so that safety performance assessment program should be prepared in integrated, objective and quantitative manner. Furthermore, the results of assessment should characterize and categorize the actual level of safety performance of specific NPP, integrating all the substantial elements for assessing the safety performance. In consideration of particular regulatory environment in Korea, the integrated safety performance assessment (ISPA) program is being under development for the use in the determination of safety performance grade (SPG) of a NPP. The ISPA program consists of 6 individual assessment programs (4 quantitative and 2 qualitative) which cover the overall safety performance of NPP. Some of the assessment programs which are already implemented are used directly or modified for incorporating risk aspects. The others which are not existing regulatory programs are newly developed. Eventually, all the assessment results from individual assessment programs are produced and integrated to determine the safety performance grade of a specific NPP

Rai Sajjad Saif

Full Text Available This paper investigates the stagnation point flow of second grade nanomaterial towards a nonlinear stretching surface subject to variable surface thickness. The process of heat transfer is examined through the melting heat and mixed convection effects. Further novel features regarding Brownian motion and thermophoresis are present. Boundary-layer approximation is employed in the problem formulation. Momentum, energy and concentration equations are converted into the non-linear ordinary differential system through the appropriate transformations. Convergent solutions for resulting problem are computed. Behaviors of various sundry variables on temperature and concentration are studied in detail. The skin friction coefficient and heat and mass transfer rates are also computed and analyzed. Our results indicate that the temperature and concentration distributions are enhanced for larger values of thermophoresis parameter. Further the present work is hoped to be useful in improving the performance of heat transfer of base fluid.

To determine whether a graded exercise program used in the treatment of anorexia nervosa improves quality of life and does not decrease the rate of gain of body fat. A randomized controlled trial with outcome measures: change in percent body fat, body mass index (BMI), and Medical Outcomes Survey Short Form 36-item Quality of Life questionnaire. Fifteen females and one male meeting the DSM-IV criteria for the diagnosis of anorexia nervosa were randomized. There was no difference in change in BMI or percent body fat at 3 months. Quality of life outcomes improved from baseline in the experimental group compared with the control group. However, this difference was not statistically significant. Incorporation of a graded exercise program may increase compliance with treatment, but it did not reduce the short-term rate of gain of body fat or BMI. Longer studies with more subjects are necessary to determine the usefulness of a graded exercise program in anorexia nervosa. Copyright 2000 by John Wiley & Sons, Inc.

Understanding groundwater - students' pre-conceptions and conceptual change by a theory-guided multimedia learning program

Science.gov (United States)

Unterbruner, U.; Hilberg, S.; Schiffl, I.

2015-11-01

Groundwater is a crucial topic in education for sustainable development. Nevertheless, international studies with students of different ages have shown that the basic hydrogeological concept of groundwater defined as water within porous and permeable rocks is not an established everyday notion. Building upon international research a multimedia learning program ("Between the raincloud and the tap") was developed. Insights from the fields of conceptual change research, multimedia research, and the Model of Educational Reconstruction were specifically implemented. Two studies were conducted with Austrian pupils (7th grade) and teacher training students from the fields of biology and geography in order to ascertain the effectiveness of the learning program. Using a quasi-experimental research design, the participants' conceptions and knowledge regarding groundwater were determined in a pre- and post-test. The pupils and students greatly profited from independently working through the learning software. Their knowledge of groundwater increased significantly compared to the control group and there was a highly significant increase in the number of scientifically correct notions of groundwater. The acceptance of the program was also generally very high. The results speak for the fact that theory-guided multimedia learning programs can play an important role in the transfer of research results into the classroom, particularly in science education.

Pfeiffer, Beth; Rai, Gillian; Murray, Tammy; Brusilovskiy, Eugene

2015-04-01

The purpose of the research was to study changes in handwriting legibility among kindergarten, first- and second-grade students in response to the Size Matters curricular-based handwriting program. A two-group pre-post-test design was implemented at two public schools with half of the classrooms assigned to receive the Size Matters program and the other continuing to receive standard instruction. All participants completed two standardized handwriting measures at pre-test and after 40 instructional sessions were completed with the classes receiving the handwriting program. Results identified significant changes in legibility in the handwriting intervention group for all three grades when compared with the standard instruction group. The results of this study support the use of a curricular-embedded handwriting program and provide the foundation for future research examining the impact of handwriting legibility on learning outcomes.

The objective of our study was to evaluate incidence rates and profile of school program ski and snowboard-related injuries by school grade group using a historical cohort design. Injuries were identified via Accident Report Forms completed by ski patrollers. Severe injury was defined as those with ambulance evacuation or recommending patient transport to hospital. Poisson regression analysis was used to examine the school grade group-specific injury rates adjusting for risk factors (sex, activity, ability, and socioeconomic status) and accounting for the effect of clustering by school. Forty of 107 (37%) injuries reported were severe. Adolescents (grades 7-12) had higher crude injury rates (91 of 10 000 student-days) than children (grades 1-3: 25 of 10 000 student-days; grades 4-6: 65 of 10 000 student-days). Those in grades 1-3 had no severe injuries. Although the rate of injury was lower in grades 1-3, there were no statistically significant grade group differences in adjusted analyses. Snowboarders had a higher rate of injury compared with skiers, while higher ability level was protective. Participants in grades 1-3 had the lowest crude and adjusted injury rates. Students in grades 7-12 had the highest rate of overall and severe injuries. These results will inform evidence-based guidelines for school ski/snowboard program participation by school-aged children. © 2017 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

Reflecting on an impact evaluation of the Grade R programme: Method, results and policy responses

Directory of Open Access Journals (Sweden)

Marie-Louise Samuels

2015-08-01

Full Text Available This paper describes the expansion since 2001 of a public pre-school programme in South Africa known as ‘Grade R’, summarises the findings from an impact evaluation of the introduction of Grade R, discusses the policy recommendations flowing from the evaluation and reflects on the process of implementing the recommendations. The Grade R programme has expanded dramatically, to the point where participation is nearly universal. Although a substantial literature points to large potential benefits from pre-school educational opportunities, the impact evaluation reported on in this article demonstrated that the Grade R programme, as implemented until 2011, had a limited impact on later educational outcomes. Improving the quality of Grade R, especially in schools serving low socio-economic status communities, thus emerges as a key policy imperative. Recommended responses include professionalising Grade R teachers, providing practical in-service support, increasing access to appropriate storybooks, empowering teachers to assess the development of their learners, and improving financial record-keeping of Grade R expenditure by provincial education departments. The impact evaluation was initiated by the Department of Planning, Monitoring and Evaluation (DPME and the Department of Basic Education (DBE, and was conducted by independent researchers. The move towards increased evaluation of key government programmes is important for shifting the focus of programme managers and policymakers towards programme outcomes rather than only programme inputs. Yet the process is not without its challenges: following a clear process to ensure the implementation of the lessons learned from such an evaluation is not necessarily straightforward.

To address the effectiveness of a formal postbaccalaureate (PB) experience for underrepresented minority (URM) students before medical school. The program provided an intense year-long experience of course work, research, and personal development. There were 516 participants from one medical school: 15 URM medical students had completed the formal PB program, 58 students had done independent PB work before matriculation, and 443 students were traditional matriculants. Cognitive and academic indicators [college science and non-science grade-point averages (GPAs); biology, physics, and verbal MCAT scores; and percentage scores from first-year medical school courses] were compared for the three groups. Both groups of students with PB experience demonstrated competency in the first year of medical school consistent with traditional students even though the students who had completed the formal PB program had lower MCAT scores and lower college GPAs than did the traditional students. Traditional predictors of academic performance during the first year of medical school did not significantly contribute to actual academic performances of students from the formal PB program. The results support the use of a formal PB program to provide academic readiness and support for URM students prior to medical school. Such a program may also improve retention. Noncognitive variables, however, may be important to understanding the success of such students in medical school.

To assess the effect of age on pre- and post-conization HPV genotype distribution. The present retrospective observational study included consecutive women with high-grade cervical intraepithelial neoplasia who underwent conization at the Cervical Cancer Screening Centre of Reggio Emilia, Italy, and University Hospital of Modena, Italy, between February 1, 2012, and October 31, 2014. Pre-conization and 6-month post-conization HPV genotyping results were compared between four age groups (<30, 30-39, 40-49, and ≥50 years) and age-related changes in the HPV genotypes present were evaluated. There were 162 patients included. The lowest occurrence of pre-conization high-risk and probable high-risk HPV genotypes was observed among patients aged at least 50 years when compared with younger patients (P=0.017). Conversely, women aged at least 50 years exhibited the highest level of post-conization high-risk and probable high-risk HPV genotypes (P=0.043). Additionally, an increasing incidence of recording identical pre- and post-conization HPV genotypes was associated with increasing age (P=0.024), as was increasing post-treatment recurrence of cervical intraepithelial neoplasia grade 2+ (P=0.030). The presence of high-risk and probable high-risk HPV genotypes was lowest among older patients before conization and was highest among these patients post-conization; post-treatment HPV clearance decreased with age and increasing age could be a risk factor for post-conization recurrence. © 2017 International Federation of Gynecology and Obstetrics.

2011-01-01

We developed and piloted a program for first-grade students to promote development of legible handwriting and writing fluency. The Write Start program uses a coteaching model in which occupational therapists and teachers collaborate to develop and implement a handwriting-writing program. The small-group format with embedded individualized supports allows the therapist to guide and monitor student performance and provide immediate feedback. The 12-wk program was implemented with 1 class of 19 students. We administered the Evaluation of Children's Handwriting Test, Minnesota Handwriting Assessment, and Woodcock-Johnson Fluency and Writing Samples test at baseline, immediately after the Write Start program, and at the end of the school year. Students made large, significant gains in handwriting legibility and speed and in writing fluency that were maintained at 6-mo follow-up. The Write Start program appears to promote handwriting and writing skills in first-grade students and is ready for further study in controlled trials.

We aimed to evaluate the diagnostic potential of dual-time-point imaging with positron emission tomography (PET) using O-(2-[{sup 18}F]fluoroethyl)-L-tyrosine ({sup 18}F-FET) for non-invasive grading of cerebral gliomas compared with a dynamic approach. Thirty-six patients with histologically confirmed cerebral gliomas (21 primary, 15 recurrent; 24 high-grade, 12 low-grade) underwent dynamic PET from 0 to 50 min post-injection (p.i.) of {sup 18}F-FET, and additionally from 70 to 90 min p.i. Mean tumour-to-brain ratios (TBR{sub mean}) of {sup 18}F-FET uptake were determined in early (20-40 min p.i.) and late (70-90 min p.i.) examinations. Time-activity curves (TAC) of the tumours from 0 to 50 min after injection were assigned to different patterns. The diagnostic accuracy of changes of {sup 18}F-FET uptake between early and late examinations for tumour grading was compared to that of curve pattern analysis from 0 to 50 min p.i. of {sup 18}F-FET. The diagnostic accuracy of changes of the TBR{sub mean} of {sup 18}F-FET PET uptake between early and late examinations for the identification of HGG was 81 % (sensitivity 83 %; specificity 75 %; cutoff - 8 %; p < 0.001), and 83 % for curve pattern analysis (sensitivity 88 %; specificity 75 %; p < 0.001). Dual-time-point imaging of {sup 18}F-FET uptake in gliomas achieves diagnostic accuracy for tumour grading that is similar to the more time-consuming dynamic data acquisition protocol. (orig.)

Horwood, Anna M; Toor, Sonia S; Riddell, Patricia M

2015-01-01

Purpose This study investigated whether vergence and accommodation development in pre-term infants is pre-programmed or is driven by experience. Methods 32 healthy infants, born at mean 34 weeks gestation (range 31.2-36 weeks) were compared with 45 healthy full-term infants (mean 40.0 weeks) over a 6 month period, starting at 4-6 weeks post-natally. Simultaneous accommodation and convergence to a detailed target were measured using a Plusoptix PowerRefII infra-red photorefractor as a target moved between 0.33m and 2m. Stimulus/response gains and responses at 0.33m and 2m were compared by both corrected (gestational) age and chronological (post-natal) age. Results When compared by their corrected age, pre-term and full-term infants showed few significant differences in vergence and accommodation responses after 6-7 weeks of age. However, when compared by chronological age, pre-term infants’ responses were more variable, with significantly reduced vergence gains, reduced vergence response at 0.33m, reduced accommodation gain, and increased accommodation at 2m, compared to full-term infants between 8-13 weeks after birth. Conclusions When matched by corrected age, vergence and accommodation in pre-term infants show few differences from full-term infants’ responses. Maturation appears pre-programmed and is not advanced by visual experience. Longer periods of immature visual responses might leave pre-term infants more at risk of development of oculomotor deficits such as strabismus. PMID:26275135

2010-06-01

A new grading system for bladder cancer (BCa) was adopted in 2004 to reduce observer variability and provide better prognostic information. We compared the World Health Organization (WHO) 1973 and 2004 systems for observer variability and prognosis. Slides of 173 primary non-muscle-invasive BCa were reviewed two times by four pathologists. Intra- and interobserver variability were assessed using κ statistics. We determined the mean grade (eg, G1/low malignant potential is 1 grade point, G2/low grade is 2 grade points) of the pathologists per grading cycle. Kaplan-Meier analyses were applied for prediction of recurrence and progression. For WHO 2004 and 1973 grading, the agreement between the pathologists was 39-74% (κ: 0.14-0.58) and 39-64% (κ: 0.15-0.41), respectively. The intraobserver agreement varied from 71% to 88% (κ: 0.55-0.81). The mean grade of a pathologist was constant (difference below 0.1 grade point) irrespective of the grading system. Conversely, mean-grade differences among the pathologists were high, up to 0.7 grade point. The mean grades for the WHO 2004 system were 0.3-0.5 grade point higher than those of WHO 1973. Mean grade distinguished low and high graders among the pathologists and was strongly linked with risk of progression in each grade category. The variation in mean grade among individual pathologists exceeded the grade shift caused by WHO 2004 grading. Knowledge of the pathologist's mean grade allows a better assessment of the prognostic value of grading. Mean grade has the potential to become a tool for quality assurance in pathology.

The study draws on the preProgress in International Reading Literacy Study (prePIRLS 2011 data, which places South African Grade 4 learners' results substantially below the international centre point of 500 at 461 (SE = 3.7. Selected items from the prePIRLS 2011 learner, parent and teacher questionnaires were used in a two-level model to determine the effect of learner aptitude, opportunity to learn and quality of instructional events on reading literacy achievement. The results point to the statistical significance of engaged reading and cultivating motivation for reading among learners from an early age, specifically through parental involvement in introducing early literacy activities as foundation of reading literacy by school-going age. Other results provide evidence for the importance of the value of reading across the curriculum not confined to formal reading lessons only. The teaching of reading comprehension skills and strategies is identified as a significant predictor of reading literacy achievement, instruction of which should form an integral part of teaching reading in the classroom.

The Pre-Major in Astronomy Program (Pre-MAP) is a research and mentoring program for underclassmen and transfer students offered by the University of Washington Astronomy Department since 2005. The primary goal of Pre-MAP is to recruit and retain students from groups traditionally underrepresented in science, technology, engineering, and mathematics (STEM) through early exposure to research. The Pre-MAP seminar is the core component of the program and offers instruction in computing skills, data manipulation, science writing, statistical analysis, and scientific speaking and presentation skills. Students choose research projects proposed by faculty, post-docs and graduate students in areas related to astrophysics, planetary science, and astrobiology. Pre-MAP has been successful in retaining underrepresented students in STEM fields relative to the broader UW population, and we've found these students are more likely to graduate and excel academically than their peers. As of spring 2015, more than one hundred students have taken the Pre-MAP seminar, and both internal and external evaluations have shown that all groups of participating students report an increased interest in astronomy and science careers at the end of the seminar. Several former Pre-MAP students have obtained or are pursuing doctoral and master’s degrees in STEM fields; many more work at NASA centers, teaching colleges, or as engineers or data analysts. Pre- MAP student research has produced dozens of publications in peer-reviewed research journals. This talk will provide an overview of the program: the structure of the seminar, examples of projects completed by students, cohort-building activities outside the seminar, funding sources, recruitment strategies, and the aggregate demographic and achievement data of our students. It is our hope that similar programs may be adopted successfully at other institutions.

2008-01-01

Cemented carbides with a functionally graded structure have significantly improved mechanical properties and lifetimes in cutting, drilling and molding. In this work, WC-6 wt.% Co cemented carbides with three-layer graded structure (surface layer rich in WC, mid layer rich in Co and the inner part of the average composition) were prepared by carburizing pre-sintered η-phase-containing cemented carbides. The three-point bending fatigue tests based on the total-life approach were conducted on both WC-6wt%Co functionally graded cemented carbides (FGCC) and conventional WC-6wt%Co cemented carbides. The functionally graded cemented carbide shows a slightly higher fatigue limit (∼100 MPa) than the conventional ones under the present testing conditions. However, the fatigue crack nucleation behavior of FGCC is different from that of the conventional ones. The crack nucleates preferentially along the Co-gradient and perpendicular to the tension surface in FGCC, while parallel to the tension surface in conventional cemented carbides

Discussion of Regulatory Guide 7.10, emphasizing the graded approach for establishing QA programs

International Nuclear Information System (INIS)

Gordon, L.; Lake, W.H.

1983-01-01

To assist applicants in establishing an acceptable QA program to meet the programmatic elements of Appendix E to 10 CFR Part 71, Regulatory Guide 7.10 was developed. Regulatory Guide 7.10 is organized in three self-contained ANNEXES. Guidance applicable to designer/fabricators, to users, and users of radiographic devices are in separate annexes. QA programs for packaging to transport radioactive material are similar in regard to the various operations a licensee may be involved in. However, the appropriate QA/QC effort to verify the program elements may vary significantly. This is referred to as the graded approach. Appendix A in the guide addresses the graded approach

Tapia, Martha; Marsh, George E

2006-01-01

This study was conducted to examine the effects of sex and grade-point average (GPA) on emotional intelligence on secondary students as measured by the Emotional Intelligence Inventory (EII). The EII is a 41-item Likert scale based on the original theoretical model of emotional intelligence developed by Salovey and Mayer. An exploratory factor analysis identified four factors, which were named Empathy, Utilization of Feelings, Handling Relationships, and Self-control. The sample consisted of 319 students, 162 males and 157 females, who attended school at a bilingual (English and Spanish) college preparatory school. General linear analysis revealed significant differences in empathy scores when grouped by gender. There were significant differences in self-control when grouped by GPA levels.

Al-Wardy, Nadia M; Rizvi, Syed G; Bayoumi, Riad A

2009-12-01

To investigate if any correlation exists between students' grades on their final doctor of Medicine (MD) assessment and their overall preclinical grade point average (GPA) and its component parts. Student data available from the Deanship of Admissions and Registration were analyzed. Pearson correlation coefficient was obtained to assess the degree of linear relationship between performance in the preclinical and the MD assessment of 529 students who graduated from the College of Medicine and Health Sciences, Sultan Qaboos University, Al-Khoud, Oman from June 1998 to June 2005. Simple and multiple regression analyses were performed to evaluate individual and combined impact of the preclinical courses' grades on MD grades. Preclinical GPA correlated highly with MD GPA (r=0.641). The science component taught early in the preclinical phase correlated more strongly (r=0.457) than student electives (r=0.246). This correlation was better in the good English group. Students' performance, however, was best in electives, but worst in English. Most students who had low MD GPA (2.5, and limiting the credit hour requirement of electives by the College seems to be justified.

Markham, Christine M; Peskin, Melissa F; Shegog, Ross; Baumler, Elizabeth R; Addy, Robert C; Thiel, Melanie; Escobar-Chaves, Soledad Liliana; Robin, Leah; Tortolero, Susan R

2014-02-01

An earlier randomized controlled trial found that two middle school sexual education programs-a risk avoidance (RA) program and a risk reduction (RR) program-delayed initiation of sexual intercourse (oral, vaginal, or anal sex) and reduced other sexual risk behaviors in ninth grade. We examined whether these effects extended into 10th grade. Fifteen middle schools were randomly assigned to RA, RR, or control conditions. Follow-up surveys were conducted with participating students in 10th grade (n = 1,187; 29.2% attrition). Participants were 60% female, 50% Hispanic, and 39% black; seventh grade mean age was 12.6 years. In 10th grade, compared with the control condition, both programs significantly delayed anal sex initiation in the total sample (RA: adjusted odds ratio [AOR], .64, 95% confidence interval [CI], .42-.99; RR: AOR, .65, 95% CI, .50-.84) and among Hispanics (RA: AOR, .53, 95% CI, .31-.91; RR: AOR, .82, 95% CI, .74-.93). Risk avoidance students were less likely to report unprotected vaginal sex, either by using a condom or by abstaining from sex (AOR: .61, 95% CI, .45-.85); RR students were less likely to report recent unprotected anal sex (AOR: .34, 95% CI, .20-.56). Both programs sustained positive impact on some psychosocial outcomes. Although both programs delayed anal sex initiation into 10th grade, effects on the delayed initiation of oral and vaginal sex were not sustained. Additional high school sexual education may help to further delay sexual initiation and reduce other sexual risk behaviors in later high school years.

Predicting Future Reading Problems Based on Pre-reading Auditory Measures: A Longitudinal Study of Children with a Familial Risk of Dyslexia.

Science.gov (United States)

Law, Jeremy M; Vandermosten, Maaike; Ghesquière, Pol; Wouters, Jan

2017-01-01

Purpose: This longitudinal study examines measures of temporal auditory processing in pre-reading children with a family risk of dyslexia. Specifically, it attempts to ascertain whether pre-reading auditory processing, speech perception, and phonological awareness (PA) reliably predict later literacy achievement. Additionally, this study retrospectively examines the presence of pre-reading auditory processing, speech perception, and PA impairments in children later found to be literacy impaired. Method: Forty-four pre-reading children with and without a family risk of dyslexia were assessed at three time points (kindergarten, first, and second grade). Auditory processing measures of rise time (RT) discrimination and frequency modulation (FM) along with speech perception, PA, and various literacy tasks were assessed. Results: Kindergarten RT uniquely contributed to growth in literacy in grades one and two, even after controlling for letter knowledge and PA. Highly significant concurrent and predictive correlations were observed with kindergarten RT significantly predicting first grade PA. Retrospective analysis demonstrated atypical performance in RT and PA at all three time points in children who later developed literacy impairments. Conclusions: Although significant, kindergarten auditory processing contributions to later literacy growth lack the power to be considered as a single-cause predictor; thus results support temporal processing deficits' contribution within a multiple deficit model of dyslexia.

Full Text Available Introduction: Family centres in Sweden are integrated services that reach all prospective parents and parents with children up to their sixth year, because of the co-location of the health service with the social service and the open pre-school. The personnel on the multi-professional site work together to meet the needs of the target group. The article explores a program theory focused on the open pre-schools at family centres.Method: A multi-case design is used and the sample consists of open pre-schools at six family centres. The hypothesis is based on previous research and evaluation data. It guides the data collection which is collected and analysed stepwise. Both parents and personnel are interviewed individually and in groups at each centre.Findings: The hypothesis was expanded to a program theory. The compliance of the professionals was the most significant element that explained why the open access service facilitated positive parenting. The professionals act in a compliant manner to meet the needs of the children and parents as well as in creating good conditions for social networking and learning amongst the parents. Conclusion: The compliance of the professionals in this program theory of open pre-schools at family centres can be a standard in integrated and open access services, whereas the organisation form can vary. The best way of increasing the number of integrative services is to support and encourage professionals that prefer to work in a compliant manner.

The effects of musical training on movement pre-programming and re-programming abilities: an event-related potential investigation.

Science.gov (United States)

Anatürk, Melis; Jentzsch, Ines

2015-03-01

Two response precuing experiments were conducted to investigate effects of musical skill level on the ability to pre- and re-programme simple movements. Participants successfully used advance information to prepare forthcoming responses and showed response slowing when precue information was invalid rather than valid. This slowing was, however, only observed for partially invalid but not fully invalid precues. Musicians were generally faster than non-musicians, but no group differences in the efficiency of movement pre-programming or re-programming were observed. Interestingly, only musicians exhibited a significant foreperiod lateralized readiness potential (LRP) when response hand was pre-specified or full advance information was provided. These LRP findings suggest increased effector-specific motor preparation in musicians than non-musicians. However, here the levels of effector-specific preparation did not predict preparatory advantages observed in behaviour. In sum, combining the response precuing and ERP paradigms serves a valuable tool to examine influences of musical training on movement pre- or re-programming processes. Copyright © 2015 Elsevier B.V.

Foraminal syringomyelia: suggestion for a grading system.

Science.gov (United States)

Versari, P P; D'Aliberti, G; Talamonti, G; Collice, M

1993-01-01

The standard treatment of foraminal syringomyelia includes foramen magnum decompression and duraplasty. Improvement or stabilization of the disease are achieved in most of cases. However, at least one third of patients are reported to receive little or no benefit. In this paper we retrospectively reviewed a series of 40 consecutive foramen magnum decompressions in order to identify the possible pre-operative outcome predictors. Based on clinical evolution, neurological impairment and radiological features, a scale of severity was fixed and retrospectively tested. A pre-operative score was obtained for each patient and was correlated with the surgical results. Then a four level grading system was derived. All grade I and grade II patients achieved good results (improvement or stabilization), whereas grade III patients showed intermediate behaviour and grade IV invariably worsened. On this basis, surgical results of foramen magnum decompression might be further improved provided that a careful pre-operative selection is made.

The Pre-Major in Astronomy Program (Pre-MAP) is a research and mentoring program for entering undergraduate students offered by the University of Washington Astronomy Department since 2005. The primary goal of Pre-MAP is to recruit and retain students from groups traditionally underrepresented in science, technology, engineering, and mathematics (STEM) through early exposure to guided research projects. The Pre-MAP seminar is the core component of the program and offers instruction in computing skills, data manipulation, science writing, statistical analysis, and scientific speaking and presentation skills. Students choose research projects proposed by faculty, post-docs and graduate students in areas related to astrophysics, planetary science, and astrobiology. Pre-MAP has been successful in retaining underrepresented students in STEM fields relative to the broader UW population, and we've found these students are more likely to graduate and excel academically than their peers. As of fall 2015, more than one hundred students have taken the Pre-MAP seminar, and both internal and external evaluations have shown that all groups of participating students report an increased interest in astronomy and science careers at the end of the seminar. This talk will provide an overview of the program and the structure of the core seminar. In particular, the talk will focus on additions and revisions to the seminar course over the last few years, such as the introduction of a public speaking coach, career and internship modules, and the formalization of external lab tours.

2012-12-01

Full Text Available In the open-pit mining, one of the first decisions that must be made in production planning stage, after completing the design of final pit limits, is determining of the processing plant cut-off grade. Since this grade has an essential effect on operations, choosing the optimum cut-off grade is of considerable importance. Different goals may be used for determining optimum cut-off grade. One of these goals may be maximizing the output rate (amount of product per year, which is very important, especially from marketing and market share points of view. Objective of this research is determining the optimum cut-off grade of processing plant in order to maximize output rate. For performing this optimization, an Operations Research (OR model has been developed. The object function of this model is output rate that must be maximized. This model has two operational constraints namely mining and processing restrictions. For solving the model a heuristic method has been developed. Results of research show that the optimum cut-off grade for satisfying pre-stated goal is the balancing grade of mining and processing operations, and maximum production rate is a function of the maximum capacity of processing plant and average grade of ore that according to the above optimum cut-off grade must be sent to the plant.

2013-01-01

This article explores the development of psychosocial competence in boys of color (BOC; 226 African Americans and 109 Latinos). Changes in competence were assessed over 2 years in cohorts of low-income BOC beginning in pre-K, kindergarten, or first grade. Psycho-social competence was assessed in terms of self-regulation, interpersonal skills, and positive relationships with peers and teachers. Psycho-social and academic competence in literacy and math were assessed in prekindergarten through second grade using teacher reports, child reports, and normed measures. One-year follow-up data were available on measures of psycho-social competence. BOC evidenced high levels of psycho-social competence, especially on self-regulation, which was related to both math and reading achievement. Teachers and children held similarly favorable views of their relationships, but teacher ratings of peer relationships of BOC were less positive. Although emotional self-regulation was stable, declines were observed in self-regulation of attention, quality of peer relationships, teacher-rated closeness, and satisfaction with life at school, especially over the transition from pre-K to primary school. © 2013 American Orthopsychiatric Association.

Keith, L; Hollar, D

2012-07-01

This study assessed the impact of a pre-medical pipeline program on successful completion of medical school and the capacity of this program to address achievement gaps experienced by disadvantaged students. The University of North Carolina (USA) Medical Education Development (MED) program provides intensive academic and test skills preparation for admission to medical, dental, and other allied health professions schools. This retrospective study evaluated the academic progress of a longitudinal sample of 1738 disadvantaged college students who completed MED between 1974 and 2001. Data sources included MED participant data, medical school admissions data for the host school, aggregate data from the Association of American Medical Colleges (AAMC), and individual MED participant data from AAMC. Methods of analysis utilized Chi-square, independent samples t test, and logistic regression to examine associations between factors. Of the 935 students in MED from 1974 to 2001, who had indicated an interest in medical school, 887 (94.9%) successfully matriculated and 801 (85.7%) successfully earned the MD degree. Using logistic regression, factors that were significantly correlated with earning the medical degree included the student's race, college undergraduate total and science grade point averages, with Hispanic, African American, and Native American participants earning the medical degree at rates comparable to Caucasian participants. MED students successfully earned the MD degree despite having significantly lower Medical College Admissions Test (MCAT) scores and undergraduate grade point averages compared to all United States medical school applicants: MCAT scores had little relationship with student's success. These findings suggest that an intensive, nine-week, pre-medical academic enrichment program that incorporates confidence-building and small-group tutoring and peer support activities can build a foundation on which disadvantaged students can successfully earn

Understanding groundwater - students' pre-conceptions and conceptual change by means of a theory-guided multimedia learning program

Science.gov (United States)

Unterbruner, Ulrike; Hilberg, Sylke; Schiffl, Iris

2016-06-01

Education on the subject of groundwater is crucial for sustainability. Nevertheless, international studies with students across different age groups have shown that the basic hydrogeological concept of groundwater defined as water within porous and permeable rocks is not an established everyday notion. Drawing from international research, a multimedia learning program Zwischen Regenwolke und Wasserhahn (between the rain cloud and the tap) was developed, which incorporates specific insights from the fields of conceptual change research, multimedia research, and the model of educational reconstruction. The effectiveness of the learning program was ascertained by means of two studies with Austrian seventh grade pupils as well as teacher-training students from the fields of biology and geography in order to ascertain the effectiveness of the learning program. Using a quasi-experimental research design, the participants' conceptions and knowledge of groundwater were determined in a pre- and post-test. The pupils and students greatly benefitted from working through the learning software independently. Their knowledge of groundwater increased significantly compared to the control group and there was a highly significant increase in the number of scientifically correct notions of groundwater. The acceptance of the program was also generally very high. The results indicate that theory-guided multimedia learning programs can play an important role in the transfer of research results to classroom settings, especially in science education.

[Purpose] The purpose of the present study was to compare the sensory thresholds of healthy subjects using pre-programmed or single-frequency transcutaneous electrical nerve stimulation. [Subjects] Ninety healthy adult subjects were randomly assigned to pre-programmed or single-frequency stimulation groups, each consisting of 45 participants. [Methods] Sensory thresholds were measured in the participants' forearms using von Frey filaments before and after pre-programmed or single-frequency transcutaneous electrical nerve stimulation, and the result in values were analyzed. [Results] Significant increases in sensory threshold after stimulation were observed in both groups. However, there were no significant differences between the two groups in sensory thresholds after stimulation or in the magnitude of threshold increases following stimulation. [Conclusion] Our results show that there are no differences between sensory threshold increases induced by pre-programmed and single-frequency transcutaneous electrical nerve stimulation.

Ansari, Arya; Winsler, Adam

2014-11-01

Within the United States, there are a variety of early education models and curricula aimed at promoting young children's pre-academic, social, and behavioral skills. This study, using data from the Miami School Readiness Project (MSRP; Winsler et al., 2008, 2012), examined the school readiness gains of low-income Latino ( n = 7,045) and Black children ( n = 6,700) enrolled in two different types of Title-1 public school pre-K programs: those in programs using the Montessori curricula and those in more conventional programs using the High/Scope curricula with a literacy supplement. Parents and teachers reported on children's socio-emotional and behavioral skills with the Devereux Early Childhood Assessment (DECA), while children's pre-academic skills (cognitive, motor, and language) were assessed directly with the Learning Accomplishment Profile Diagnostic (LAP-D) at the beginning and end of their four-year-old pre-K year. All children, regardless of curricula, demonstrated gains across pre-academic, socio-emotional, and behavioral skills throughout the pre-K year; however, all children did not benefit equally from Montessori programs. Latino children in Montessori programs began the year at most risk in pre-academic and behavioral skills, yet exhibited the greatest gains across these domains and ended the year scoring above national averages. Conversely, Black children exhibited healthy gains in Montessori, but demonstrated slightly greater gains when attending more conventional pre-K programs. Findings have implications for tailoring early childhood education programs for Latino and Black children from low-income communities.

This study examined the relative contributions of measures of attention problems and hyperactivity to the prediction of college grade point average (GPA). A sample of 316 students enrolled in introductory psychology and sociology classes at a southeastern university completed the BASC-2 Self-Report of Personality College Form. Scores on the attention problems scale and the hyperactivity scale of the BASC-2 were entered into a regression equation as predictors of cumulative GPA. Each of the independent variables made a significant contribution to the prediction of GPA. Attention problem scores alone explained 7% of the variability in GPAs. The addition of hyperactivity scores to the equation produced a 2% increase in explanatory power. The implications of these results for assessing symptoms of inattention and hyperactivity in college students are discussed.

The skills of computer programming is a core competency that must be mastered by students majoring in computer sciences. The best way to improve this skill is through the practice of writing many programs to solve various problems from simple to complex. It takes hard work and a long time to check and evaluate the results of student labs one by one, especially if the number of students a lot. Based on these constrain, web proposes Automatic Grading Tools (AGT), the application that can evaluate and deeply check the source code in C, C++. The application architecture consists of students, web-based applications, compilers, and operating systems. Automatic Grading Tools (AGT) is implemented MVC Architecture and using open source software, such as laravel framework version 5.4, PostgreSQL 9.6, Bootstrap 3.3.7, and jquery library. Automatic Grading Tools has also been tested for real problems by submitting source code in C/C++ language and then compiling. The test results show that the AGT application has been running well.

Udomkan, Watinee; Suwannoi, Paisan

2018-01-01

A training program was developed for enhancing pre-service science teachers' pedagogical content knowledge (PCK). The pre-service science teachers are able to: understand science curriculum, knowledge of assessment in science, knowledge of students' understanding of science, instructional strategies and orientations towards science teaching, which is conceptualized as PCK [5]. This study examined the preservice science teachers' understandings and their practices which include five pre-service science teachers' PCK. In this study, the participants demonstrated their PCK through the process of the training program by writing content representations (CoRes), preparing the lesson plans, micro-teaching, and actual teaching respectively. All pre-service science teachers' performs were collected by classroom observations. Then, they were interviewed. The results showed that the pre-service science teachers progressively developed knowledge components of PCK. Micro-teaching is the key activities for developing PCK. However, they had some difficulties in their classroom teaching. They required of sufficient ability to design appropriate instructional strategies and assessment activities for teaching. Blending content and pedagogy is also a matter of great concern. The implication of this study was that science educators can enhance pre-service science teachers' PCK by fostering their better understandings of the instructional strategies, assessment activities and blending between content and pedagogy in their classroom.

Pre-eclampsia is an important cause of maternal and fetal morbidity and mortality that is associated with decreased placental perfusion. In the present study, vascular corrosion casting was used to investigate the differences in structural changes of the fetoplacental vasculature between normal and pre-eclamptic placentas. An improved epoxy resin vascular casting technique was used in the present study. Casting media were infused into 40 normal and 40 pre-eclamptic placentas through umbilical arteries and veins in order to construct three dimensional fetoplacental vasculatures. The number of branches, diameter, morphology and peripheral artery-to-vein ratio were measured for each specimen. The results indicated that the venous system of normal placentas was divided into 5-7 grades of branches and the volume of the vascular bed was 155.5±45.3 ml. In severe pre-eclamptic placentas, the volume was 106.4±36.1 ml, which was significantly lower compared with normal placentas (P<0.01). The venous system of pre-eclamptic placentas was divided into 4-5 grades of branches, which was much more sparse compared with normal placentas. In additions, the diameters of grade 1-3 veins and grade 2-3 arteries were significantly smaller in severe pre-eclampsia (P<0.05). In conclusion, pre-eclamptic placentas displayed a decreased volume of vascular bed, smaller diameters of grade 1-3 veins and grade 2-3 arteries, and an increased peripheral artery-to-vein ratio, which may be a cause of the placental dysfunction during severe pre-eclampsia.

Here, we report on findings from a 15-month follow-up of a school-based program called Empowering a Multimodal Pathway Toward Healthy Youth (EMPATHY). This was primarily intended to reduce suicidal thinking in pre-teens, adolescents, and youth students aged 11–18 in middle schools (Grades 6–8) and high SCHOOLS (Grades 9–12). It also aimed to reduce depression and anxiety. The EMPATHY multimodal program consisted of repeated data collection, identification of a high-risk group, a rapid intervention for this high-risk group including offering supervised online cognitive behavioral therapy (CBT) program, a universal CBT intervention for those in Grades 6–8, a variety of interactions with trained staff (“Resiliency Coaches”), and referral to external medical and psychiatric services where appropriate. There were four time-points at which assessments were made: baseline, 3, 7, and 15 months. Here, we report cross-sectional findings over 15 months in a total of 6,227 students who were assessed at least once during the study period. Additionally, we report longitudinal findings from the 1,884 students who completed all 4 assessments. Our results found highly statistically significant decreases in suicidality rates, with the percentage of the total school population who were actively suicidal decreasing from 4.4% at baseline (n = 143 of 3,244) to 2.8% at 15 months (n = 125 of 4,496) (p < 0.001). There were also highly statistically significant reductions in depression and anxiety scores at each time-point. Thus, Mean Depression scores at baseline for the entire student population were 3.73 ± 3.87 (n = 3,244) at baseline and decreased to 3.22 ± 3.52 (n = 4,496) (p < 0.001). Since most students were not depressed, whole population changes such as this may indicate impact in many areas. In the longitudinal analysis of students who completed all four assessments, there were also highly statistically significant improvements

Because of obsolescing the components used in safety related systems of nuclear power plants, decreasing the number of suppliers qualified for the nuclear QA program and increasing maintenance costs of them, utilities have been considering to use commercial grade digital computers as an alternative for resolving such issues. However, commercial digital computers use the embedded pre-existing software, including operating system software, which are not developed by using nuclear grade QA program. Thus, it is necessary for utilities to establish processes for dedicating digital commercial grade items. A regulatory body also needs guidance to evaluate the digital commercial products properly. This paper surveyed the regulations and their regulatory guides, which establish the requirements for commercial grade items dedication, industry standards and guidances applicable to safety related systems. This paper provides some guidelines to be applied in evaluating the safety of digital upgrades and new digital plant protection systems in Korea

A consistent finding from many reviews is that undergraduate Grade Point Average (uGPA) is a key predictor of academic success in medical school. Curiously, while uGPA has established predictive validity, little is known about its reliability. For a variety of reasons, medical schools use different weighting schemas to combine years of study. Additional concerns relate to the equivalence of grades obtained from different fields of study and institutions, with little hard data to guide conclusions. At the Michael G. DeGroote School of Medicine Class of 2007 at McMaster University, every undergraduate grade of 2,138 applicants, along with field of study and post-secondary educational institution, was analyzed. Individual grades were aggregated into an overall uGPA using published algorithms from several medical school, and correlated with a non-weighted sum. Correlations of the different schemas with equal weights ranged from 0.973 to 0.990. The extent of the difference between fields of study was small, accounting for only 1.5% of the variance. However, differences among 16 Ontario universities were larger, and accounted for 9.3% of the variance. The results of this study suggest that all weighting schemas are virtually equivalent, making any formulation reasonable. Differences by field of study are small, but do not show any bias against non-science students. Differences by institution are larger, amounting to a range in average score from 78.7 to 84.6; however it is not clear whether this reflects candidate ability or institutional policy, so attempts to correct for institution may be difficult.

2011-01-01

Abstract The past three decades have seen an explosion of research interest in spinal cord injury (SCI) and the development of hundreds of potential therapies that have demonstrated some promise in pre-clinical experimental animal models. A growing number of these treatments are seeking to be translated into human clinical trials. Conducting such a clinical trial, however, is extremely costly, not only for the time and money required to execute it, but also for the limited resources that will then no longer be available to evaluate other promising therapies. The decision about what therapies have sufficient pre-clinical evidence of efficacy to justify testing in humans is therefore of utmost importance. Here, we have developed a scoring system for objectively grading the body of pre-clinical literature on neuroprotective treatments for acute SCI. The components of the system include an evaluation of a number of factors that are thought to be important in considering the “robustness” of a therapy's efficacy, including the animal species and injury models that have been used to test it, the time window of efficacy, the types of functional improvements effected by it, and whether efficacy has been independently replicated. The selection of these factors was based on the results of a questionnaire that was performed within the SCI research community. A modified Delphi consensus-building exercise was then conducted with experts in pre-clinical SCI research to refine the criteria and decide upon how to score them. Finally, the grading system was applied to a series of potential neuroprotective treatments for acute SCI. This represents a systematic approach to developing an objective method of evaluating the extent to which the pre-clinical literature supports the translation of a particular experimental treatment into human trials.

THE INFLUENCE OF THE TOOL POINT ANGLE AND FEED RATE ON THE DELAMINATION AT DRILLING OF PRE-LAMINATED PARTICLEBOARD

Directory of Open Access Journals (Sweden)

Mihai ISPAS

2015-12-01

Full Text Available Pre-laminated particleboard is a wood based composite extensively used in the furniture industry. Drilling is the most common machining process which prepares the panels for joining using twist/helical drills in the absolute majority of cases. The point angle of the drill bit and the feed speed during drilling play a major role in gaining a good surface quality and minimizing the delamination tendency of the pre-laminated particleboard. The objective of this study was to measure and analyze the influence of the two above-mentioned factors on the processing quality, evaluated by de size of delaminations, both, at the entrance side and the exit side of the drill bit. To assess the defect, two parameters were used: the delamination factor and the effective area of delamination. The results showed that, in general, the combination of small point angle with low feed rate minimizes the delamination of pre-laminated particleboard panels at drilling.

Full Text Available Cervical cancer continues to be a major public health problem in India in the absence of wide spread organised cervical screening programs. Visual inspection of the cervix with acetic acid (VIA is an effective, inexpensive screening test that can be combined with simple treatment procedures for early cervical lesions, provided by trained health workers. We report 7 years experience in early detection of cervical cancer and pre-cancers using the VIA test in a community-based program in rural Andhra Pradesh, India where there are no existing organised cervical screening programs. Materials and Methods: Eligible women aged between 26 and 60 were opportunistically screened by trained health wor kers using the VIA test. Women who tested positive were further evaluated and those with cervical lesions were treated either by cryotherapy in the screening clinic or referred to a higher center. Results: A total of 18,869 women were screened by a single round of VIA testing with a positive rate of 10.75%. Biopsy proven high-grade squamous intraepithelials (HSILs were 90 (0.48% and low-grade squamous intraepithelials (LSILs were 43 (0.28%. The overall prevalence of cervical intraepithelial neoplasia (CIN 2+ lesion rate is 1.05%. A total of 312 (1.65% cryotherapies were done and 49 women underwent hysterectomy. Conclusions: VIA by trained female health workers is a safe, acceptable, and effective test that can save lives from cervical cancer even in remote areas with few resources. These results have important implications for efficient service delivery in cervical screening programs in low-resourced settings.

2016-01-01

The current focus on assessing “college and career readiness” raises an empirical question: How do high school tests compare with college admissions tests in predicting performance in college? We explored this using data from the City University of New York and public colleges in Kentucky. These two systems differ in the choice of college admissions test, the stakes for students on the high school test, and demographics. We predicted freshman grade point average (FGPA) from high school GPA an...

Is the Sky Falling? Grade Inflation and the Signaling Power of Grades.

Science.gov (United States)

Pattison, Evangeleen; Grodsky, Eric; Muller, Chandra

2013-06-01

Grades are the fundamental currency of our educational system; they signal academic achievement and non-cognitive skills to parents, employers, postsecondary gatekeepers, and students themselves. Grade inflation compromises the signaling value of grades, undermining their capacity to achieve the functions for which they are intended. We challenge the 'increases in grade point average' definition of grade inflation and argue that grade inflation must be understood in terms of the signaling power of grades. Analyzing data from four nationally representative samples, we find that in the decades following 1972: (a) grades have risen at high schools and dropped at four-year colleges, in general, and selective four-year institutions, in particular; and (b) the signaling power of grades has attenuated little, if at all.

The aurora, Mars, and more! Increasing science content in elementary grades through art and literacy programs in earth and space science

Science.gov (United States)

Renfrow, S.; Wood, E. L.

2011-12-01

Although reading, writing, and math examinations are often conducted early in elementary school, science is not typically tested until 4th or 5th grade. The result is a refocus on the tested topics at the expense of the untested ones, despite that standards exist for each topic at all grades. On a national level, science instruction is relegated to a matter of a few hours per week. A 2007 Education Policy study states that elementary school students spend an average of 178 minutes a week on science while spending 500 minutes on literacy. A recent NSTA report in July of elementary and middle school teachers confirms that teachers feel pressured to teach math and literacy at the expense of other programs. One unintended result is that teachers in grades where science is tested must play catch-up with students for them to be successful on the assessment. A unique way to combat the lack of science instruction at elementary grades is to combine literacy, social studies, and math into an integrated science program, thereby increasing the number of science contact hours. The Dancing Lights program, developed at the Laboratory for Atmospheric and Space Physics, is a science, art, and literacy program about the aurora designed to easily fit into a typical 3rd-5th grade instructional day. It mirrors other successful literacy programs and will provide a basis for the literacy program being developed for the upcoming MAVEN mission to Mars. We will present early findings, as well as "lessons learned" during our development and implementation of the Dancing Lights program and will highlight our goals for the MAVEN mission literacy program.

2014-01-01

The current study examined relationships among self-reported depression severity, posttraumatic stress disorder (PTSD) symptom severity, and grade point average (GPA) among student servicemembers and veterans. We asked 422 student servicemembers and veterans (72% male, 86% Caucasian, mean age = 36.29 yr) to complete an anonymous online survey that assessed self-reported GPA, depression severity, PTSD severity, and frequency of academic problems (late assignments, low grades, failed exams, and skipped classes). Female respondents reported a slightly higher GPA than males (3.56 vs 3.41, respectively, p = 0.01). Depression symptoms (beta weight = -0.174, p = 0.03), male sex (beta weight = 0.160, p = 0.01), and younger age (beta weight = 0.155, p = 0.01) were associated with lower GPA but not PTSD symptoms (beta weight = -0.040, p = 0.62), although the interaction of depression and PTSD symptoms showed a nonsignificant inverse relationship with GPA (beta weight = -0.378, p = 0.08). More severe depression was associated with turning in assignments late (beta weight = 0.171, p = 0.03), failed exams (beta weight = 0.188, p = 0.02), and skipped classes (beta weight = 0.254, p = 0.01). The relationship of depression with self-reported GPA was mediated by frequency of failed examns. Results suggest that student servicemembers and veterans with greater emotional distress also report worse academic performance.

DeWald, Janice P; Gutmann, Marylou E; Solomon, Eric S

2004-01-01

Passing the National Board Dental Hygiene Examination is a requirement for licensure in all but one state. There are a number of preparation courses for the examination sponsored by corporations and dental hygiene programs. The purpose of this study was to determine if taking a board review course significantly affected student performance on the board examination. Students from the last six dental hygiene classes at Baylor College of Dentistry (n = 168) were divided into two groups depending on whether they took a particular review course. Mean entering college grade point averages (GPA), exiting dental hygiene program GPAs, and National Board scores were compared for the two groups using a t-test for independent samples (p < 0.05). No significant differences were found between the two groups for entering GPA and National Board scores. Exiting GPAs, however, were slightly higher for those not taking the course compared to those taking the course. In addition, a strong correlation (0.71, Pearson Correlation) was found between exiting GPA and National Board score. Exiting GPA was found to be a strong predictor of National Board performance. These results do not appear to support this program's participation in an external preparation course as a means of increasing students' performance on the National Board Dental Hygiene Examination.

Loewe, Thomas; Mundlamuri, Ramesh; Loewe, Thomas; Mundrigi, Ashok; Handt, Sebastian; Singh, Bhuwan

2017-12-14

Cytotoxic drugs can be encapsulated in liposomes vesicles, which act as drug delivery vehicles and reduce the risk of exposure of drug to healthy cells(1). The sterility of such liposome solutions is typically ensured using 0.2μm rated sterilizing grade membranes, but due to the high viscosity and low surface tension of these formulations, they can cause pre-mature blocking and increased risk of bacterial penetration through a 0.2μm sterilizing grade membrane(2). The low surface tension of liposome solutions affects the contact angle with membrane and reduces bubble point leading to bacterial penetration through the membrane. This poses a great challenge to select an appropriate sterilizing grade membrane for a given process and for filter manufacturers to develop a sterilizing grade membrane that specifically addresses these needs. In this study, the influence of different variables that could affect the total throughput and bacterial retention performance of different membranes types on processing of liposome solutions have been evaluated. Based on the results, we conclude that the membrane properties e.g., surface porosity, surface tension, pore size, symmetry/asymmetry, hydrophilicity and liposome properties e.g., composition, lipid size and concentration affect bacterial retention and total throughput capacity. Process parameters such as temperature, pressure and flow should also be optimized to improve process efficiency. Copyright © 2017, Parenteral Drug Association.

2017-09-01

Full Text Available The purpose of this study was to investigate attitudes of pre-service teachers toward the teaching profession with respect to their gender, grade level, whether participants regularly participate in physical activities, and whether pre-service students have a teacher-parent in their family. Research was conducted on 469 pre-service physical education teachers (Mage=21.35, SDage= 2.49, 188 female (Mage=20.89, SDage= 2.30 and 281 male (Mage=21.66, SDage= 2.57 students from five different universities in Turkey. In this study the “Attitude Scale for the Profession of Physical Education Teaching” was used. It has two factors: “concern for profession” (CP and “affection for profession” (AP. Independent sample t-test results indicated that there were no significant differences with respect to gender or having a teacher-parent in both factors and total attitude points (p> 0.05. Pre-service physical education teachers who participate in physical activity had significantly higher points in AP and the total scale in comparison to those who do not participate in physical activity (p< 0.05. ANOVA results indicated that based on grade level there were significant differences in CP and total attitude (p< 0.05. Students’ concern about employment may be associated with differences in attitude scores between grade levels. The positive effect of physical activity participation and their professional teaching education on stress resilience might also be an important factor for increasing positive attitudes toward the teaching profession.

Many factors influence pre-hospital delays in the event of stroke. This study aimed to develop and evaluate a comprehensive educational program for decreasing pre-hospital delays in high-risk stroke population. We enrolled 220 high-risk stroke population and caregivers from six urban communities in Harbin from May 2013 to May 2015, and randomly divided them into intervention and control groups. We implemented a comprehensive educational program (intervention group), comprising public lectures, instructional brochures, case videos, simulations, and role-playing from May 2013 to May 2015. We delivered conventional oral education in the control group. We compared stroke pre-hospital delay behavioral intention (SPDBI), pre-hospital stroke symptom coping test (PSSCT), and stroke pre-symptoms alert test (SPSAT) results between the groups before and 6, 12, and 18 months after health intervention. There were significant differences between before and after intervention (P educational program was significantly effective in decreasing SPDBI, improving knowledge, enhancing stroke pre-symptoms alert, and reducing the possibility of pre-hospital delays.

Early familiarity is regarded as one of the keys to attracting female students to traditionally male professions. I will describe four different extra curricular programs that my collaborators in the local school district and I have developed for students in grades 5-12. These programs are part of a project entitled "Promoting Young Women in the Physical sciences", which also includes teacher training and programs in which parents participate with the child. Through these sustained and broad-based interventions, we provide early experiences that we expect will prove positive to students. I will also address the successes and difficulties in starting and sustaining these programs.

Bonefeld, Meike; Dickhäuser, Oliver

2018-01-01

Biases in pre-service teachers’ evaluations of students’ performance may arise due to stereotypes (e.g., the assumption that students with a migrant background have lower potential). This study examines the effects of a migrant background, performance level, and implicit attitudes toward individuals with a migrant background on performance assessment (assigned grades and number of errors counted in a dictation). Pre-service teachers (N = 203) graded the performance of a student who appeared to have a migrant background statistically significantly worse than that of a student without a migrant background. The differences were more pronounced when the performance level was low and when the pre-service teachers held relatively positive implicit attitudes toward individuals with a migrant background. Interestingly, only performance level had an effect on the number of counted errors. Our results support the assumption that pre-service teachers exhibit bias when grading students with a migrant background in a third-grade level dictation assignment. PMID:29867618

From Russian weapons grade plutonium to MOX fuel

International Nuclear Information System (INIS)

Braehler, G.; Kudriavtsev, E.G.; Seyve, C.

1997-01-01

The April 1996, G7 Moscow Summit on nuclear matters provided a political framework for one of the most current significant challenges: ensuring a consistent answer to the weapons grade fissile material disposition issue resulting from the disarmament effort engaged by both the USA and Russia. International technical assessments have showed that the transformation of Weapons grade Plutonium in MOX fuel is a very efficient, safe, non proliferant and economically effective solution. In this regard, COGEMA and SIEMENS, have set up a consistent technical program properly addressing incineration of weapons grade plutonium in MOX fuels. The leading point of this program would be the construction of a Weapons grade Plutonium dedicated MOX fabrication plant in Russia. Such a plant would be based on the COGEMA-SIEMENS industrial capabilities and experience. This facility would be operated by MINATOM which is the partner for COGEMA-SIEMENS. MINATOM is in charge of coordination of the activity of the Russian research and construction institutes. The project take in account international standards for non-proliferation, safety and waste management. France and Germany officials reasserted this position during their last bilateral summits held in Fribourg in February and in Dijon in June 1996. MINATOM and the whole Russian nuclear community have already expressed their interest to cooperate with COGEMA-SIEMENS in the MOX field. This follows governmental-level agreements signed in 1992 by French, German and Russian officials. For years, Russia has been dealing with research and development on MOX fabrication and utilization. So, the COGEMA-SIEMENS MOX proposal gives a realistic answer to the management of weapons grade plutonium with regard to the technical, industrial, cost and schedule factors. (author)

Abstract Heart Smart Program is a health education intervention for grades kindergarten through six which encourages the acquisition and maintenance of health-enhancing behaviors. These include nutritious eating habits; physical fitness and exercise; saying "no" to cigarette smoking, alcohol, and drugs; and control of stress. Social Cognitive Theory is used to derive the necessary training concepts for children with reinforcement of these concepts occurring in six areas: the curriculum, school lunch, staff development, physical activity, environment, and parental support. The necessary training mechanisms provide mastery experiences, knowledge transfer, role modeling, and emotional and physiological feedback. The program incorporates the influence of the social environment on learning and builds support from parents, teachers and school staff.

Patients with nonspecific mechanical low back pain (n = 103), examined by an orthopaedic surgeon and a social worker, were randomized to an activity group (n = 51) and a control group (n = 52). Patients with defined orthopaedic, medical, or psychiatric diagnoses were excluded before randomization. No patients were excluded due to place of birth or difficulties in speaking or understanding the Swedish language. The purpose of the study was to compare mobility, strength and fitness after traditional care and after traditional care plus a graded activity program with a behavioral therapy approach. A graded activity program, with a behavioral therapy approach was given under the guidance of a physical therapist. The endpoint of the graded activity program was return to work. This program significantly increased mobility, strength, and fitness more than could be explained by only a time recovery effect, especially in males. The patients in the activity group returned to work earlier than did the patients in the control group. Spinal rotation, abdominal muscle endurance time and lifting capacity were significantly correlated to rate of return to work. Traditional care plus a graded activity program were superior to only traditional care, evaluated in terms of mobility, strength and fitness. The graded activity program proved to be a successful method of restoring occupational function and facilitating return to work in subacute low back pain patients. The patients in the graded activity program learned that it is safe to move, while regaining function.

The method consisted in a literary review based on a systematic search in international databases (Emerald, ABI/INFORM Global, ProQuest Education Journals, ProQuest European Business, ProQuest Science Journal, ProQuest Research Library, ProQuest Psychology Journals, ProQuest Social Science Journals and Business Source Complete of studies published from January 1990 to December 2013, which explore the academic performance of students or graduates of MBA programs. A quantitative review was performed. Results show that most researchers studied relations between GMAT (Graduate Management Admission Test and UGPA (Undergraduate Grade Point Average as predictors of GGPA (Graduate Grade Point Average. On the other hand, work experience and personal traits (such as personality, motivation, learning strategies, self-efficacy beliefs and achievement expectations and their relation with GGPA had been less studied, and results are not consistent enough to consider them valid predictors of student performance at this time.

Differences in achievement between home language and language of learning in South Africa: Evidence from prePIRLS 2011

Surette van Staden

2016-11-01

Full Text Available This study utilised regression methods to explain Grade 4 reading literacy achievement taking into account discrepancies between the language of the test and home language for learners who participated in the South African preProgress in International Reading Literacy Study (prePIRLS 2011. Grade 4 learners were tested across all 11 official languages. The language of testing did not always coincide with the learner’s home language; therefore, prePIRLS 2011 test results reveal achievement for learners who in many cases did the test in a second or third language. Results from the current analyses show that testing in African languages predicts significantly lower results as compared to English, but that exponentially worse results by as much as 0.29 points lower of a standard deviation can be expected when the African language of the test did not coincide with the learners’ home language. Findings from the current study provide evidence that African children stand to be disadvantaged the most when a strong mother tongue base has not been developed and when education for children between Grade 1 and 3 is only available through a medium of instruction other than the mother tongue. Evidence that exposure to a language that at least shares linguistic similarities to the home language could have a positive effect.

2014-12-01

Leveraging the Rose Center for Earth and Space and active research departments in Earth and Planetary Science, Astrophysics, and Paleontology, the Education Department at the American Museum of Natural History (AMNH) offers an MAT program to prepare new Earth Science teachers (~100 new teachers by 2018) as well as a range of professional development (PD) opportunities for over 3,000 K-12 teachers annually, providing opportunities to learn with scientists; inquiry-based experiences; and standards-aligned resources. The AMNH produces innovative geoscience and other STEM resources supporting teacher and student science investigations with data visualizations and analysis tools, teaching case materials and other resources that provide rich nonfiction reading and writing opportunities for use in Earth and space science curricula that are integrated in the MAT and PD programs. Museum resources and the MAT and PD programs are aligned to support the recently released Next Generation Science Standards (NGSS) and the Common Core State Standards. The NGSS is a set of science and engineering practices, crosscutting concepts and disciplinary core ideas to help cultivate teachers' and K-12 students' scientific habits of mind, develop their knowledge and abilities to engage in scientific investigations, and teach them how to reason in context; goals that closely align with those of the AMNH's teacher preparation and professional development programs. A Framework for K-12 Science Education: Practices, Crosscutting Concepts, and Core Ideas (NRC, 2012) is a required text for the MAT program, and this text as well as the NGSS Performance Expectations guide the PD programs as well. Researchers working with Museum scientists and educators find it is not enough for programs for pre- and in-service teachers to provide access to resources. Research suggests that these programs need to engage pre- and in-service teachers in using and reflecting on these types of resources, as well as take

Master, Allison; Cheryan, Sapna; Moscatelli, Adriana; Meltzoff, Andrew N

2017-08-01

The gender gap in science, technology, engineering, and math (STEM) engagement is large and persistent. This gap is significantly larger in technological fields such as computer science and engineering than in math and science. Gender gaps begin early; young girls report less interest and self-efficacy in technology compared with boys in elementary school. In the current study (N=96), we assessed 6-year-old children's stereotypes about STEM fields and tested an intervention to develop girls' STEM motivation despite these stereotypes. First-grade children held stereotypes that boys were better than girls at robotics and programming but did not hold these stereotypes about math and science. Girls with stronger stereotypes about robotics and programming reported lower interest and self-efficacy in these domains. We experimentally tested whether positive experience with programming robots would lead to greater interest and self-efficacy among girls despite these stereotypes. Children were randomly assigned either to a treatment group that was given experience in programming a robot using a smartphone or to control groups (no activity or other activity). Girls given programming experience reported higher technology interest and self-efficacy compared with girls without this experience and did not exhibit a significant gender gap relative to boys' interest and self-efficacy. These findings show that children's views mirror current American cultural messages about who excels at computer science and engineering and show the benefit of providing young girls with chances to experience technological activities.

Interior Point Method for Solving Fuzzy Number Linear Programming Problems Using Linear Ranking Function

Directory of Open Access Journals (Sweden)

Yi-hua Zhong

2013-01-01

Full Text Available Recently, various methods have been developed for solving linear programming problems with fuzzy number, such as simplex method and dual simplex method. But their computational complexities are exponential, which is not satisfactory for solving large-scale fuzzy linear programming problems, especially in the engineering field. A new method which can solve large-scale fuzzy number linear programming problems is presented in this paper, which is named a revised interior point method. Its idea is similar to that of interior point method used for solving linear programming problems in crisp environment before, but its feasible direction and step size are chosen by using trapezoidal fuzzy numbers, linear ranking function, fuzzy vector, and their operations, and its end condition is involved in linear ranking function. Their correctness and rationality are proved. Moreover, choice of the initial interior point and some factors influencing the results of this method are also discussed and analyzed. The result of algorithm analysis and example study that shows proper safety factor parameter, accuracy parameter, and initial interior point of this method may reduce iterations and they can be selected easily according to the actual needs. Finally, the method proposed in this paper is an alternative method for solving fuzzy number linear programming problems.

Pre- and Post-Conditions Expressed in Variants of the Modal µ-Calculus

Science.gov (United States)

Tanabe, Yoshinori; Sekizawa, Toshifusa; Yuasa, Yoshifumi; Takahashi, Koichi

Properties of Kripke structures can be expressed by formulas of the modal µ-calculus. Despite its strong expressive power, the validity problem of the modal µ-calculus is decidable, and so are some of its variants enriched by inverse programs, graded modalities, and nominals. In this study, we show that the pre- and post-conditions of transformations of Kripke structures, such as addition/deletion of states and edges, can be expressed using variants of the modal µ-calculus. Combined with decision procedures we have developed for those variants, the properties of sequences of transformations on Kripke structures can be deduced. We show that these techniques can be used to verify the properties of pointer-manipulating programs.

Dudas, Robert A; Barone, Michael A

2014-01-01

One of the greatest challenges for clerkship directors is assigning a final grade and determining the precise point at which a student either passes or fails a clinical clerkship. The process of incorporating both subjective and objective assessment data to provide a final summative grade can be challenging. We describe our experience conducting a standard-setting exercise to set defensible cut points in a 4-tiered grading system in our pediatric clerkship. Using the Hofstee standard-setting approach, 8 faculty members participated in an exercise to establish grade cut points. These faculty members were subsequently surveyed to assess their attitudes toward the standard-setting process as well as their reactions to these newly proposed standards. We applied the new cut points to a historic cohort of 116 Johns Hopkins University School of Medicine students from the academic year 2012-2013 to assess the potential impact on grade distributions. The resultant grading schema would lead to a significant increase in the number of students receiving a failing grade and a decrease in the number of students receiving a grade of honors in a historical cohort. Faculty reported that the Hofstee method was easy to understand and fair. All faculty members thought that grade inflation presently exists within the pediatric clerkship. This study demonstrates that practical standards using the Hofstee method can be set for medical students in a pediatric clerkship in which multiple performance measures are used.

Byrd, J W Thomas; Bardowski, Elizabeth A; Jones, Kay S

2018-05-19

To define the outcomes of arthroscopic correction of femoroacetabular impingement (FAI) based on Tönnis findings within a previously reported patient population, including a comparative analysis of Tönnis grade 0 and 1 versus grade 2 changes. Outcomes (modified Harris Hip Score [mHHS]) of a previously published study of arthroscopic correction of FAI were correlated with Tönnis grade. The inclusion criteria were the first 100 consecutive patients undergoing arthroscopic FAI correction with minimum 2-year follow-up. These procedures were performed between December 2003 and May 2006. Grades were determined independently by 2 experienced clinicians. Tönnis grades 0 and 1 were compared with Tönnis grade 2. Independent variables of sex and age were also evaluated. The average age of the entire group was 34.7 years (range, 13-76 years), with 66 male and 34 female patients. Of the patients, 17 had Tönnis grade 0, 49 had Tönnis grade 1, 29 had Tönnis grade 2, and 4 had Tönnis grade 3 (1 unknown). The average mHHS improvement for Tönnis grade 0 was 20.6 points; Tönnis grade 1, 22.2 points; Tönnis grade 2, 14.9 points; and Tönnis grade 3, 18.8 points. The improvement was statistically (P 8 points) significant across all Tönnis grades. There was no difference (P = .077) between Tönnis grades 0 and 1 (21.8 points) versus grade 2 (14.9 points). There was no difference based on sex or age. These data support that statistically and clinically meaningful successful patient-reported outcomes (mHHS) at 2 years can be encountered even in the presence of Tönnis grade 2 radiographic features. Neither age nor sex was an indicator of poorer results within similar Tönnis grades. Level III, case-control study. Copyright © 2018 Arthroscopy Association of North America.

ptchg: A FORTRAN program for point-charge calculations of electric field gradients (EFGs)

Science.gov (United States)

Spearing, Dane R.

1994-05-01

ptchg, a FORTRAN program, has been developed to calculate electric field gradients (EFG) around an atomic site in crystalline solids using the point-charge direct-lattice summation method. It uses output from the crystal structure generation program Atoms as its input. As an application of ptchg, a point-charge calculation of the EFG quadrupolar parameters around the oxygen site in SiO 2 cristobalite is demonstrated. Although point-charge calculations of electric field gradients generally are limited to ionic compounds, the computed quadrupolar parameters around the oxygen site in SiO 2 cristobalite, a highly covalent material, are in good agreement with the experimentally determined values from nuclear magnetic resonance (NMR) spectroscopy.

2006-04-15

Evaluate the academic experience and satisfaction of students enrolled in the dual PharmD/MBA degree program between the South Carolina College of Pharmacy and The Citadel's School of Business Administration. Compare grade point averages of students enrolled in the dual degree program with those of traditional student colleagues. A standardized satisfaction survey instrument was administered to 32 students currently enrolled in the dual PharmD/MBA degree program. Grade point averages (GPAs) in both pharmacy and business coursework were also collected for analysis. There were slightly higher percentages of both female and minority students in the dual degree program compared to the pharmacy class as a whole. Eighteen (56%) of students completed the survey, and responses were generally positive. The mean GPA of students in the dual degree program was higher than that of both pharmacy (3.37 vs 3.08, p vs 3.64, not statistically significant) students not enrolled in the dual degree program. Students enrolled in the dual degree program did better academically than their counterparts and indicated an overall high level of satisfaction with the program.

The mission of the DOE Review of Laboratory Programs for Women is to: provide DOE and its Laboratories with effective strategies, targeting women, for establishing aggressive outreach programs which improve the access of women to careers in science, engineering, and mathematics. Ensure that the Department and its Laboratories are exemplary places of employment by providing programs which enhance opportunity, remove barriers, and assist women in achieving full professional development. A survey of the DOE facilities was undertaken by the Points-of-Contact for the DOE Review of Laboratory Programs for Women in order to gather data to be used as a baseline against which to measure future progress. We plan to look at current programs already in place and evaluate them with a view to deciding which programs are most effective, and selecting model programs suitable for implementation at other facilities. The survey focused on four areas: statistical data, laboratory policy, formal and informal programs which affect the quality of life in the work environment, and career development and advancement, and educational programs. Although this report focuses on women, the problems discussed affect all DOE facility employees.

Full Text Available This study aims to evaluate the effect of phonological awareness training program in preschool performance of 256 children in Funchal, Portugal. This is a longitudinal study from preschool (2005 to 4th grade (2011. It has an experimental design. The sample includes an Experimental Group (132 children and a Control group (124 children. We pretend to answer the following research question: To what degree does training children in phonological awareness as early as preschool have short-term and long-term effects on the evolution of students' competencies and disciplinary knowledge? A first evaluation done in 2006 on the effects of this program at the end of preschool education revealed that the Experimental Group presented significant improvements when compared to the Control Group on the considered dimensions. In 2011, the Experimental Group presented Math National Test higher significant results when compared to the Control Group. The Experimental Group's Portuguese National Test presented better results than the Control Group one, but not significantly. This seems to indicate that Phonological Awareness Program can bring benefits and prevent long-term math school failure.

2003-01-01

This study examined cognitive, academic, and attitudinal predictors of college grade point average (GPA) among college students with learning disabilities (LD). The study population included 84 youth who attended a large private university in the midwestern United States. Measures of cognitive and academic functioning, along with a self-report measure of study habits and study attitudes, were used to predict college GPA. The results indicated that Full Scale IQ and one factor on the self-reported study habits scale accounted for a significant amount of variance in students' college GPA. These findings suggest that variables other than traditional cognitive and academic skills are important for determining the performance of youth with LD during college. The implications of these findings for future research efforts and practice are discussed.

The objective of this study was to develop and evaluate the effectiveness of a school-based sleep education program aimed at improving the sleep and academic performance of school-age children. Using a community-based participatory research approach, we created a school-based sleep education program, "Sleep for Success"™ (SFS), composed of four distinct modules that addressed the children, their family and community, the school staff, and decision makers within the school setting. Implementation was carried out in three elementary schools. Seventy-one students participated in the evaluation of the program. The effectiveness of the SFS program was evaluated using non-randomized controlled before-and-after study groups (intervention and control) assessed over two time points (pre- and post-program implementation). Before (baseline) and after implementation, sleep and academic performance were measured using actigraphy and report card marks, respectively. In the intervention group, true sleep was extended by 18.2 min per night, sleep efficiency improved by 2.3%, and sleep latency was shortened by 2.3 min, and report card grades in mathematics and English improved significantly. No changes were noted in the control group. Participation in the sleep education program was associated with significant improvements in children's sleep and academic performance.

Deutsch, Miriam

2010-03-01

Recruiting and retaining women into the physical sciences is an ongoing struggle for universities, with the gap between men and women in physics remaining strong. Research shows a precipitous drop in female participation in the physical sciences around the 7th grade year of primary education, where girls begin losing interest during middle school, the drain continuing throughout high school with another significant drop at the bachelors level. To combat the loss of women in the physical sciences, the Oregon Center for Optics at the University of Oregon has created the Optical Science Discovery Program (OSDP), a precollege outreach program that targets girls in middle and high school. This program uses optical sciences as the medium through which girls explore experimental science. The program consists of a one-week intensive summer camp, a mentored monthly science club, summer internships and mentoring opportunities for camp alumni. By utilizing media often at the core of teenage life (e.g. Facebook, MySpace) we also aim to interact with program participants in a familiar and informal environment. Mentoring of OSDP activities is carried out by faculty and students of all levels. This in turn allows other education and outreach efforts at the University of Oregon to incorporate OSDP activities into their own, contributing to our broader university goals of surmounting barriers to higher education and creating a more scientifically literate populace. This talk will describe the OSDP program and its incorporation into the broader spectrum of outreach and education efforts.

Graded activity: legacy of the sanatorium.

Science.gov (United States)

Creighton, C

1993-08-01

Occupational therapists in all areas of practice grade therapeutic activities to help patients progress toward their goals. It is proposed in this paper that the concept of graded activity originated in German tuberculosis sanatoria in the late 1800s, when patients were required to walk on graded (sloped) land for exercise. British physician Marcus Paterson included work, as well as walking, in his graduated exercise program for tuberculosis patients and was honored for this innovation at the founding meeting of the National Society for the Promotion of Occupational Therapy (NSPOT). George Barton, Susan Tracy, and Herbert Hall were among the NSPOT members who contributed to the development of graded activity as a principle in occupational therapy intervention. The military rehabilitation programs established during World War I provided additional impetus, and by the mid-1920s, graded activity was recognized as central to the profession.

While pipeline programs for students from underrepresented minority groups have been established at the high school and college levels, fewer programs have been developed for middle school students. In an effort to reach this cohort, the University of Detroit Mercy School of Dentistry embarked on a grassroots collaborative pipeline program with two distinct segments: Urban Impressions and Dental Imprint. Their purpose is to expose Detroit-area seventh and eighth grade students to careers in dentistry, provide oral health education, and introduce role models. The aim of this pilot study was to determine outcomes for the middle school participants in Urban Impressions (n=86) and Dental Imprint (n=68). Both segments featured hands-on dental activities at the dental school. Outcomes were assessed by pretest-posttest surveys. Across the three cohorts, a total of 86 students participated in one or more sessions, with 57 completing the pre- and post-program surveys, for a 66% response rate. The results showed that the Dental Imprint respondents' knowledge of oral health, dental admissions, and specialties increased by an average 26% over three years. The gain in knowledge for each cohort was statistically significant (pdentistry as a career following the program. These results suggest that the two segments of this program are meeting their goals of increasing middle grade students' awareness of oral health professions including dentistry and providing access to role models. Institutions may benefit from the description of strategies used by this program to address challenges related to establishing early pipeline programs.

the purpose of this study was to describe a language stimulation program, including teacher training and practical activities in the classroom, and investigate the effectiveness of this action on the social functioning and behavioral problems of elementary school children. 136 children from six classrooms of a public school and their teachers participated in this research. Of these, half were given the language stimulation program: 16 hours of training for teachers and 9 meetings in the classroom with activities for students. The activities involved instruction for the use of language reflection and practice with the narrative structure. Teachers filled out questionnaires about the social skills and behavior problems of their students before and after the program. there was no statistically significant difference between the research groups pre- and post- program in terms of assertiveness/ social resourcefulness (1st and 5th grades) and cooperation/affection (1st and 3rd grades). In the research groups, children of the 3rd grade, different from the 1st and the 5th grade, showed more evolution in their self-control abilities, which may be related to the lower frequency of externalizing problems in this group. the language program had positive effects on social assertiveness/resourcefulness skills and social cooperation/affection.

2015-08-01

Full Text Available Visual Perception is the mind’s ability to interpret or give meaning to what is seen with the eyes (WCED 2006. Grade Reception Phase (R teachers, of five and six year-old learners, need to impart Visual Perceptual Skills (VPS during visual training for pre-reading. These prereading activities in Grade R support early reading progress in Grade 1, which is critical for improving basic literacy and numeracy education in South Africa. A quality Grade R programme which can deliver these visual training outcomes depends on a progressive model for effective pre- and in-service professional development of teachers. A model implemented via academic-governmental collaboration. This article seeks to describe and recommend best practices of such professional development. The recommendations are based on an overview of the current Grade R professional development landscape, a brief exposition of the Subject Content Knowledge (SCK of VPS, a document analysis of the Curriculum and Assessment Policy Statement (CAPS curriculum and, finally, a case study with a discourse analysis involving four Grade R teachers.

Estimating the return on investment in disease management programs using a pre-post analysis.

Fetterolf, Donald; Wennberg, David; Devries, Andrea

2004-01-01

Disease management programs have become increasingly popular over the past 5-10 years. Recent increases in overall medical costs have precipitated new concerns about the cost-effectiveness of medical management programs that have extended to the program directors for these programs. Initial success of the disease management movement is being challenged on the grounds that reported results have been the result of the application of faulty, if intuitive, methodologies. This paper discusses the use of "pre-post" methodology approaches in the analysis of disease management programs, and areas where application of this approach can result in spurious results and incorrect financial outcome assessments. The paper includes a checklist of these items for use by operational staff working with the programs, and a comprehensive bibliography that addresses many of the issues discussed.

2008-01-01

The purpose of this study was to evaluate if pre-anaesthetic thoracic radiographs contribute to the anaesthetic management of trauma patients by comparing American Society of Anesthesiologists Physical Status Classification (ASA grade) with and without information from thoracic radiography findings. Case records of 157 dogs and cats being anaesthetized with or without post-traumatic, pre-anaesthetic chest radiographs were retrospectively evaluated for clinical parameters, radiographic abnormalities and anaesthetic protocol. Animals were retrospectively assigned an ASA grade. ASA grades, clinical signs of respiratory abnormalities and anaesthesia protocols were compared between animals with and without chest radiographs. The group of animals without pre-anaesthetic radiographs was anaesthetized earlier after trauma and showed less respiratory abnormalities at presentation. The retrospectively evaluated ASA grade significantly increased with the information from thoracic radiography. Animals with a higher ASA grade were less frequently mechanically ventilated. Pre-anaesthetic radiographs may provide important information to assess the ASA grade in traumatized patients and may therefore influence the anesthesia protocol

In the U.S. Department of Veterans Affairs (VA), residential treatment programs are an important part of the continuum of care for patients with a substance use disorder (SUD). However, a limited number of program-specific measures to identify quality gaps in SUD residential programs exist. This study aimed to: (1) Develop metrics for two pre-admission processes: Wait Time and Engagement While Waiting, and (2) Interview program management and staff about program structures and processes that may contribute to performance on these metrics. The first aim sought to supplement the VA's existing facility-level performance metrics with SUD program-level metrics in order to identify high-value targets for quality improvement. The second aim recognized that not all key processes are reflected in the administrative data, and even when they are, new insight may be gained from viewing these data in the context of day-to-day clinical practice. VA administrative data from fiscal year 2012 were used to calculate pre-admission metrics for 97 programs (63 SUD Residential Rehabilitation Treatment Programs (SUD RRTPs); 34 Mental Health Residential Rehabilitation Treatment Programs (MH RRTPs) with a SUD track). Interviews were then conducted with management and front-line staff to learn what factors may have contributed to high or low performance, relative to the national average for their program type. We hypothesized that speaking directly to residential program staff may reveal innovative practices, areas for improvement, and factors that may explain system-wide variability in performance. Average wait time for admission was 16 days (SUD RRTPs: 17 days; MH RRTPs with a SUD track: 11 days), with 60% of Veterans waiting longer than 7 days. For these Veterans, engagement while waiting occurred in an average of 54% of the waiting weeks (range 3-100% across programs). Fifty-nine interviews representing 44 programs revealed factors perceived to potentially impact performance in

The Point Lepreau Environmental Monitoring Program (PLEMP) has been established within the Department of Fisheries and Oceans to assess the environmental impact of radioactive, thermal, and chemical releases from the Point Lepreau, N.B. Nuclear Generating Station (NGS) located on the Bay of Fundy. This report contains the results for the second year of the operational phase of the monitoring program. Emphasis has been placed on those areas where effects from the NGS operation were expected to be observed. Further studies were carried out on the characterization of the thermal plume during several pre-arranged tritium releases. Attention was given to tritium levels at the outfall, in the atmosphere and in biological samples. An initial attempt was made to relate the distribution of tritium in the Point Lepreau area in various phases to local meteorological conditions. Radionuclide levels in lichen, including, for the first time, aerial lichen on a regular basis, an efficient accumulator of atmospheric particulates were monitored. In addition, radionuclide measurements were made on samples collected during the pre-operational phase from the major environmental reservoirs and these radioactivity levels were compared to previous measurements to assess the impact of the operation of the NGS. The purpose of this program is to provide government with a comprehensive scientific basis upon which to assess the environmental implications of the operation of nuclear reactors in coastal regions

Peak capacity, peak-capacity production rate, and boiling point resolution for temperature-programmed GC with very high programming rates

Science.gov (United States)

Grall; Leonard; Sacks

2000-02-01

Recent advances in column heating technology have made possible very fast linear temperature programming for high-speed gas chromatography. A fused-silica capillary column is contained in a tubular metal jacket, which is resistively heated by a precision power supply. With very rapid column heating, the rate of peak-capacity production is significantly enhanced, but the total peak capacity and the boiling-point resolution (minimum boiling-point difference required for the separation of two nonpolar compounds on a nonpolar column) are reduced relative to more conventional heating rates used with convection-oven instruments. As temperature-programming rates increase, elution temperatures also increase with the result that retention may become insignificant prior to elution. This results in inefficient utilization of the down-stream end of the column and causes a loss in the rate of peak-capacity production. The rate of peak-capacity production is increased by the use of shorter columns and higher carrier gas velocities. With high programming rates (100-600 degrees C/min), column lengths of 6-12 m and average linear carrier gas velocities in the 100-150 cm/s range are satisfactory. In this study, the rate of peak-capacity production, the total peak capacity, and the boiling point resolution are determined for C10-C28 n-alkanes using 6-18 m long columns, 50-200 cm/s average carrier gas velocities, and 60-600 degrees C/min programming rates. It was found that with a 6-meter-long, 0.25-mm i.d. column programmed at a rate of 600 degrees C/min, a maximum peak-capacity production rate of 6.1 peaks/s was obtained. A total peak capacity of about 75 peaks was produced in a 37-s long separation spanning a boiling-point range from n-C10 (174 degrees C) to n-C28 (432 degrees C).

2016-01-01

Highlights: • A Maximum Power Point Tracking (MPPT) method for thermoelectric generators is proposed. • A power converter is controlled to operate on a pre-programmed locus. • The proposed MPPT technique has the advantage of operational and design simplicity. • The experimental average deviation from the MPP power of the TEG source is 1.87%. - Abstract: ThermoElectric Generators (TEGs) are capable to harvest the ambient thermal energy for power-supplying sensors, actuators, biomedical devices etc. in the μW up to several hundreds of Watts range. In this paper, a Maximum Power Point Tracking (MPPT) method for TEG elements is proposed, which is based on controlling a power converter such that it operates on a pre-programmed locus of operating points close to the MPPs of the power–voltage curves of the TEG power source. Compared to the past-proposed MPPT methods for TEGs, the technique presented in this paper has the advantage of operational and design simplicity. Thus, its implementation using off-the-shelf microelectronic components with low-power consumption characteristics is enabled, without being required to employ specialized integrated circuits or signal processing units of high development cost. Experimental results are presented, which demonstrate that for MPP power levels of the TEG source in the range of 1–17 mW, the average deviation of the power produced by the proposed system from the MPP power of the TEG source is 1.87%.

To evaluate the accuracy of the Omron MIT Elite in pregnancy and pre-eclampsia according to the British Hypertension Society protocol (BHS). Prospective observational study. Antenatal clinics and wards at St. Thomas' Hospital (London, UK). Forty-five pregnant women including 15 with pre-eclampsia. Nine sequential same arm blood pressure (BP) measurements were taken from each woman by trained observers, alternating between mercury sphygmomanometry and the test device. Grading criteria of the BHS protocol (A/B grade=pass; C/D=fail). The Omron MIT Elite achieved a grade A/A in both pregnancy and pre-eclampsia. The mean difference (SD) between the mercury standard and the device in pregnancy was -1.1 (5.2)mmHg and 1.5 (4.8)mmHg for systolic and diastolic BP respectively compared to 0.2 (5.3)mmHg and 2.2 (5.5)mmHg in pre-eclampsia. The Omron MIT Elite can be recommended for use in pregnancy and pre-eclampsia according to the BHS protocol. To date, this is the most accurate automated BP device validated in pre-eclampsia.

Purpose: To test the hypothesis that medical student radiation oncology elective rotation grades are inflated and cannot be used to distinguish residency applicants. Methods and Materials: The records of 196 applicants to a single radiation oncology residency program in 2011 and 2012 were retrospectively reviewed. The grades for each rotation in radiation oncology were collected and converted to a standardized 4-point grading scale (honors, high pass, pass, fail). Pass/fail grades were scored as not applicable. The primary study endpoint was to compare the distribution of applicants' grades in radiation oncology with their grades in medicine, surgery, pediatrics, and obstetrics/gynecology core clerkships. Results: The mean United States Medical Licensing Examination Step 1 score of the applicants was 237 (range, 188-269), 43% had additional Masters or PhD degrees, and 74% had at least 1 publication. Twenty-nine applicants were graded for radiation oncology rotations on a pass/fail basis and were excluded from the final analysis. Of the remaining applicants (n=167), 80% received the highest possible grade for their radiation oncology rotations. Grades in radiation oncology were significantly higher than each of the other 4 clerkships studied (P<.001). Of all applicants, 195 of 196 matched into a radiation oncology residency. Higher grades in radiation oncology were associated with significantly higher grades in the pediatrics core clerkship (P=.002). However, other medical school performance metrics were not significantly associated with higher grades in radiation oncology. Conclusions: Although our study group consists of a selected group of radiation oncology applicants, their grades in radiation oncology clerkships were highly skewed toward the highest grades when compared with grades in other core clerkships. Student grading in radiation oncology clerkships should be re-evaluated to incorporate more objective and detailed performance metrics to allow for

PLC (Programmable Logic Controller)-based Software development, the design programs are translated into implementation programs, and behavioral equivalence between the design and implementation is demonstrated by formal method based technique. In FPGA-based software development, the design programs are also synthesized into implementation programs. However, in this process, testing and simulation based comparison techniques are mainly used. This paper proposes a formal method based technique to demonstrate behavioral equivalence between pre-synthesis and post-synthesis programs with VIS (Verification Interacting with Synthesis) verification system. We translated into BLIF-MV which is front-end of VIS, from Verlag and EDIF net list which synthesized from the same Verlag by an automatic synthesis tool. This paper proposes a formal method based technique to confirm correctness of synthesis by using equivalence checking of VIS verification system. In order to confirm the effectiveness of the proposed technique, we performed a case study with a part of prototype version of the RPS BP, and demonstrated a behavioral equivalence between Verlag HDL and EDIF post-synthesis net list.

However, in this process, testing and simulation based comparison techniques are mainly used. This paper proposes a formal method based technique to demonstrate behavioral equivalence between pre-synthesis and post-synthesis programs with VIS (Verification Interacting with Synthesis) verification system. We translated into BLIF-MV which is front-end of VIS, from Verlag and EDIF net list which synthesized from the same Verlag by an automatic synthesis tool. This paper proposes a formal method based technique to confirm correctness of synthesis by using equivalence checking of VIS verification system. In order to confirm the effectiveness of the proposed technique, we performed a case study with a part of prototype version of the RPS BP, and demonstrated a behavioral equivalence between Verlag HDL and EDIF post-synthesis net list

College grade point average as a personnel selection device: ethnic group differences and potential adverse impact.

Science.gov (United States)

Roth, P L; Bobko, P

2000-06-01

College grade point average (GPA) is often used in a variety of ways in personnel selection. Unfortunately, there is little empirical research literature in human resource management that informs researchers or practitioners about the magnitude of ethnic group differences and any potential adverse impact implications when using cumulative GPA for selection. Data from a medium-sized university in the Southeast (N = 7,498) indicate that the standardized average Black-White difference for cumulative GPA in the senior year is d = 0.78. The authors also conducted analyses at 3 GPA screens (3.00, 3.25, and 3.50) to demonstrate that employers (or educators) might face adverse impact at all 3 levels if GPA continues to be implemented as part of a selection system. Implications and future research are discussed.

The long-term impact of a math, science and technology program on grade school girls

Science.gov (United States)

Sullivan, Sandra Judd

The purpose of this study was to determine if a math, science, and technology intervention program improved grade school girls' attitudes and stereotypes toward science and scientists, as well as participation levels in science-related activities, two years after their participating in the program. The intervention program evaluated was Operation SMART, developed by Girls Incorporated. Participants were recruited from the 6th and 7th grades from two public middle schools in Northern California. One hundred twenty-seven girls signed up for the survey and were assigned to either the SMART group (previous SMART participants) or Non-SMART group (no previous experience with SMART). The survey consisted of five parts: (1) a background information sheet, (2) the Modified Attitudes Toward Science Inventory, (3) the What Do You Do? survey, (4) the Draw-A-Scientist Test-Revised, and (5) a career interests and role models/influencer survey. Results indicated that there were no significant differences between the SMART and Non-SMART groups on any of the test measures. However, middle school attended did have a significant effect on the outcome variables. Girls from Middle School A reported more positive attitudes toward science, while girls from Middle School B reported higher participation levels in extracurricular science activities. Possible explanations for these findings suggest too much time had passed between treatment effect and time of measurement as well as the strong influence of teacher and school environment on girls' attitudes and stereotypes. Recommendations for future research are discussed.

Can we predict podiatric medical school grade point average using an admission screen?

Science.gov (United States)

Shaw, Graham P; Velis, Evelio; Molnar, David

2012-01-01

Most medical school admission committees use cognitive and noncognitive measures to inform their final admission decisions. We evaluated using admission data to predict academic success for podiatric medical students using first-semester grade point average (GPA) and cumulative GPA at graduation as outcome measures. In this study, we used linear multiple regression to examine the predictive power of an admission screen. A cross-validation technique was used to assess how the results of the regression model would generalize to an independent data set. Undergraduate GPA and Medical College Admission Test score accounted for only 22% of the variance in cumulative GPA at graduation. Undergraduate GPA, Medical College Admission Test score, and a time trend variable accounted for only 24% of the variance in first-semester GPA. Seventy-five percent of the individual variation in cumulative GPA at graduation and first-semester GPA remains unaccounted for by admission screens that rely on only cognitive measures, such as undergraduate GPA and Medical College Admission Test score. A reevaluation of admission screens is warranted, and medical educators should consider broadening the criteria used to select the podiatric physicians of the future.

2013-01-01

Pre-admission factors tend to serve as indicators of student success in health professions educational programs, but less is known about the effects that academic assistance programs have on student success. This study sought to determine whether specific pre-admission factors could help to identify students who may require academic support during their health professions education. This retrospective analysis aimed to identify differences in pre-admission variables between those students requiring tutoring and a matched sample of students who did not require tutoring. One-way ANOVA was used to assess differences for dependent variables-age, cumulative GPA (cGPA), science GPA (sGPA), verbal graduate record examination (GRE) score, quantitative GRE score, analytical GRE score and combined GRE score, community college hours, average credit hours per semester, and highest semester credit hour load-across three groups of students who received no tutoring (NT 0 hrs), some tutoring (ST tutoring (MT >8 hrs). Total GRE and average semester hours differentiated NT from ST from MT (ptutoring: quantitative GRE, sGPA, cGPA and average semester hours taken. The combination of lower GRE scores and lighter average semester course load were most predictive of the need for academic assistance as defined by hours of tutoring. While the value of the GRE in admissions processes is generally accepted, the average semester hour load in college can also provide important information regarding academic preparation and the need for tutoring services.

PET AND SPECT STUDIES IN CHILDREN WITH HEMISPHERIC LOW-GRADE GLIOMAS

Juhász, Csaba; Bosnyák, Edit

2016-01-01

Molecular imaging is playing an increasing role in the pre-treatment evaluation of low-grade gliomas. While glucose positron emission tomography (PET) can be helpful to differentiate low-grade from high-grade tumors, PET imaging with amino acid radiotracers has several advantages, such as better differentiation between tumors and non-tumorous lesions, optimized biopsy targeting and improved detection of tumor recurrence. This review provides a brief overview of single photon emission computed tomography (SPECT) studies followed by a more detailed review of clinical applications of glucose and amino acid PET imaging in low-grade hemispheric gliomas. We discuss key differences in the performance of the most commonly utilized PET radiotracers and highlight the advantage of PET/MRI fusion to obtain optimal information about tumor extent, heterogeneity and metabolism. Recent data also suggest that simultaneous acquisition of PET/MR images and the combination of advanced MRI techniques with quantitative PET can further improve the pre- and post-treatment evaluation of pediatric brain tumors.

There is almost no report on pre-operative irradiation therapy in biliary tract cancer. For the purpose of attaining improved operative results, pre-operative irradiation has so for been performed in our department. We experienced 106 cases of biliary tract cancer during the period from January 1982 to December 1990, including 30 cases treated by pre-operative irradiation. Among 30 cases, 20 cases, including 9 cases of gallbladder cancer and 11 cases of bile duct cancer, were resectable. Final histopathological findings were obtained in 8 cases of gallbladder cancer and 9 cases of bile duct cancer. The effectiveness of irradiation was evaluated according to the histopathological criteria proposed by Ohboshi and Shimosato in 1971. Four cases were Grade I, 2 cases were Grade IIA, and 2 cases were Grade IIB, and 1 case was Grade III of bile duct cancer. In both groups, no correlation was observed between the exposure doses and their effects. Although no correlation was noted between the degree of differentiation of tubular adenocarcinoma of microscopic pathological findings and the irradiation effects, 1 case of poorly differentiated tubular adenocarcinoma of the bile duct was evaluated as Grade III. Mucinous adenocarcinoma and papillary adenocarcinoma of the gallbladder were revealed to be Grade I. According to the main affected site of bile duct cancer, a good irradiation effect was obtained in patients with upper to middle bile duct cancer. The irradiation effect on the gallbladder and the bile duct wall was predominant on the mucous side but less effective on the serous side. From the histopathological findings, the effectiveness of pre-operative irradiation was suggested. These results suggested that the further clinical evaluation, such as rates of resection or prognostic outcome would be relevant. (author)

Full Text Available In this study, researchers evaluate a homework exercise assigned before a standalone information literacy session. Students in a Master of Education program completed a worksheet using the ERIC database thesaurus. The researchers conducted pre- and posttests within a single library session to assess student learning, using a control group for comparison. The treatment group did not demonstrate better thesaurus skills than students who had regular library instruction alone, but results pointed the way to targeted improvements of pre-session learning materials. This approach could inform other information literacy homework applications such as flipping the classroom.

2001-06-01

OBJECTIVE: To determine whether grade point average, hours of clinical education, or both are significant predictors of performance on the National Athletic Trainers' Association Board of Certification examination and whether curriculum and internship candidates' scores on the certification examination can be differentially predicted. DESIGN AND SETTING: Data collection forms and consent forms were mailed to the subjects to collect data for predictor variables. Subject scores on the certification examination were obtained from Columbia Assessment Services. SUBJECTS: A total of 270 first-time candidates for the April and June 1998 certification examinations. MEASUREMENTS: Grade point average, number of clinical hours completed, sex, route to certification eligibility (curriculum or internship), scores on each section of the certification examination, and pass/fail criteria for each section. RESULTS: We found no significant difference between the scores of men and women on any section of the examination. Scores for curriculum and internship candidates differed significantly on the written and practical sections of the examination but not on the simulation section. Grade point average was a significant predictor of scores on each section of the examination and the examination as a whole. Clinical hours completed did not add a significant increment for any section but did add a significant increment for the examination overall. Although no significant difference was noted between curriculum and internship candidates in predicting scores on sections of the examination, a significant difference by route was found in predicting whether candidates would pass the examination as a whole (P =.047). Proportion of variance accounted for was less than R(2) = 0.0723 for any section of the examination and R(2) = 0.057 for the examination as a whole. CONCLUSIONS: Potential predictors of performance on the certification examination can be useful to athletic training educators in

Kaszczak, Lesia

With the adoption of the Common Core State Standards in New York State and the Next Generation Science Standards, it is more important than ever for school districts to develop professional development programs to provide teachers with the resources that will assist them in incorporating the new standards into their classroom instruction. This study focused on a mathematics and science professional development program known as STEMtastic STEM. The two purposes of the study were: to determine if there is an increase in STEM content knowledge of the participants involved in year two of a three year professional development program and to examine the teachers' perceptions of the impact of the professional development program on classroom instruction. The sample included teachers of grades 7-12 from an urban school district in New York State. The scores of a content knowledge pre-test and post-test were analyzed using a paired sample t-test to determine any significant differences in scores. In order to determine mathematics and science teachers' perceptions of the impact of the professional development program, responses from a 22 item Likert-style survey were analyzed to establish patterns of responses and to determine positive and negative perceptions of participants of the professional development program. A single sample t-test was used to determine if the responses were significantly positive. The results of this study indicated that there was no significant increase in content knowledge as a result of participation in the STEMtastic STEM professional development program. Both mathematics and science teachers exhibited significant positive perceptions of items dealing with hands-on participation during the professional development; support provided by STEMtastic STEM specialists; and the support provided by the administration. It was concluded that both mathematics and science teachers responded positively to the training they received during the professional

BNL NONLINEAR PRE TEST SEISMIC ANALYSIS FOR THE NUPEC ULTIMATE STRENGTH PIPING TEST PROGRAM

International Nuclear Information System (INIS)

DEGRASSI, G.; HOFMAYER, C.; MURPHY, C.; SUZUKI, K.; NAMITA, Y.

2003-01-01

The Nuclear Power Engineering Corporation (NUPEC) of Japan has been conducting a multi-year research program to investigate the behavior of nuclear power plant piping systems under large seismic loads. The objectives of the program are: to develop a better understanding of the elasto-plastic response and ultimate strength of nuclear piping; to ascertain the seismic safety margin of current piping design codes; and to assess new piping code allowable stress rules. Under this program, NUPEC has performed a large-scale seismic proving test of a representative nuclear power plant piping system. In support of the proving test, a series of materials tests, static and dynamic piping component tests, and seismic tests of simplified piping systems have also been performed. As part of collaborative efforts between the United States and Japan on seismic issues, the US Nuclear Regulatory Commission (USNRC) and its contractor, the Brookhaven National Laboratory (BNL), are participating in this research program by performing pre-test and post-test analyses, and by evaluating the significance of the program results with regard to safety margins. This paper describes BNL's pre-test analysis to predict the elasto-plastic response for one of NUPEC's simplified piping system seismic tests. The capability to simulate the anticipated ratcheting response of the system was of particular interest. Analyses were performed using classical bilinear and multilinear kinematic hardening models as well as a nonlinear kinematic hardening model. Comparisons of analysis results for each plasticity model against test results for a static cycling elbow component test and for a simplified piping system seismic test are presented in the paper

The rhythm of breathing in mammals, originating within the brainstem pre-Bötzinger complex (pre-BötC), is presumed to be generated by glutamatergic neurons, but this has not been directly demonstrated. Additionally, developmental expression of the transcription factor Dbx1 or expression of the neuropeptide somatostatin (Sst), has been proposed as a marker for the rhythmogenic pre-BötC glutamatergic neurons, but it is unknown whether these other two phenotypically defined neuronal populations are functionally equivalent to glutamatergic neurons with regard to rhythm generation. To address these problems, we comparatively investigated, by optogenetic approaches, the roles of pre-BötC glutamatergic, Dbx1-derived, and Sst-expressing neurons in respiratory rhythm generation in neonatal transgenic mouse medullary slices in vitro and also more intact adult perfused brainstem-spinal cord preparations in situ. We established three different triple-transgenic mouse lines with Cre-driven Archaerhodopsin-3 (Arch) expression selectively in glutamatergic, Dbx1-derived, or Sst-expressing neurons for targeted photoinhibition. In each line, we identified subpopulations of rhythmically active, Arch-expressing pre-BötC inspiratory neurons by whole-cell recordings in medullary slice preparations in vitro, and established that Arch-mediated hyperpolarization of these inspiratory neurons was laser power dependent with equal efficacy. By site- and population-specific graded photoinhibition, we then demonstrated that inspiratory frequency was reduced by each population with the same neuronal voltage-dependent frequency control mechanism in each state of the respiratory network examined. We infer that enough of the rhythmogenic pre-BötC glutamatergic neurons also have the Dbx1 and Sst expression phenotypes, and thus all three phenotypes share the same voltage-dependent frequency control property.

Point-of-care blood gas test results may benefit therapeutic decision making by their immediate impact on patient care. We evaluated the (pre-)analytical performance of a novel cartridge-type blood gas analyzer, the GEM Premier 5000 (Werfen), for the determination of pH, partial carbon dioxide pressure (pCO 2 ), partial oxygen pressure (pO 2 ), sodium (Na + ), potassium (K + ), chloride (Cl - ), ionized calcium ( i Ca 2+ ), glucose, lactate, and total hemoglobin (tHb). Total imprecision was estimated according to the CLSI EP5-A2 protocol. The estimated total error was calculated based on the mean of the range claimed by the manufacturer. Based on the CLSI EP9-A2 evaluation protocol, a method comparison with the Siemens RapidPoint 500 and Abbott i-STAT CG8+ was performed. Obtained data were compared against preset quality specifications. Interference of potential pre-analytical confounders on co-oximetry and electrolyte concentrations were studied. The analytical performance was acceptable for all parameters tested. Method comparison demonstrated good agreement to the RapidPoint 500 and i-STAT CG8+, except for some parameters (RapidPoint 500: pCO 2 , K + , lactate and tHb; i-STAT CG8+: pO 2 , Na + , i Ca 2+ and tHb) for which significant differences between analyzers were recorded. No interference of lipemia or methylene blue on CO-oximetry results was found. On the contrary, significant interference for benzalkonium and hemolysis on electrolyte measurements were found, for which the user is notified by an interferent specific flag. Identification of sample errors from pre-analytical sources, such as interferences and automatic corrective actions, along with the analytical performance, ease of use and low maintenance time of the instrument, makes the evaluated instrument a suitable blood gas analyzer for both POCT and laboratory use.

The Curtin Coaches: Benefits of an outreach tutoring program for first year pre-service teachers. A Practice Report

Directory of Open Access Journals (Sweden)

Saul Karnovsky

2015-03-01

Full Text Available The Curtin Coaches program represents a dynamic outreach opportunity for pre-service teachers enrolled in their first year of study at Curtin University to engage with school-aged students as classroom tutors. Research has shown that cross-age tutoring experiences in schools can benefit both the students receiving support and those who tutor, particularly in settings where individuals are engaging in community support work. According to program feedback, participants were able to develop a range of profession-related skills such as relationship building and gain new knowledge such as understanding how students learn. These competencies are salient as they align with the newly implemented standards for graduate teachers. Understanding the benefits such outreach programs bring pre-service teachers is vital as the future of HEPPP funded programs such as the Curtin Coaches is uncertain but the importance of Work Integrated Learning is increasing.

2016-01-01

Focusing on the continuity in the quality of classroom environments as children transition from preschool into elementary school, this study examined the associations between classroom quality in pre-kindergarten and kindergarten and children’s social skills and behavior problems in kindergarten and first grade. Participants included 1175 ethnically-diverse children (43% African American) living in low-wealth rural communities of the US. Results indicated that children who experienced higher levels of emotional and organizational classroom quality in both pre-kindergarten and kindergarten demonstrated better social skills and fewer behavior problems in both kindergarten and first grade comparing to children who did not experience higher classroom quality. The examination of the first grade results indicated that the emotional and organizational quality of pre-kindergarten classrooms was the strongest predictor of children’s first grade social skills and behavior problems. The study results are discussed from theoretical, practical, and policy perspectives. PMID:26949286

MFDFA and Lacunarity Analysis of Synthetic Multifractals and Pre-Cancerous Tissues

Science.gov (United States)

Roy, A.; Das, N.; Ghosh, N.

2017-12-01

Multifractal Detrended Fluctuation Analysis (MFDFA) has been employed for evaluating complex variations in the refractive index (RI) of human pre-cancerous tissues. While this was primarily aimed towards the early diagnosis of cancer in the human cervix, question remains whether multifractal analysis alone can be conclusively used for distinguishing between various grades of pre-cancerous tissues. Lacunarity is a parameter that was developed for multiscale analysis of data and has been shown to be theoretically related to the correlation dimension, D2, by dlog(L)/dlog(x) = D2 - 2. Further, research has proven that not only can Lacunarity be used as a preliminary indicator of multifractal behavior but it also distinguishes between images with similar correlation dimension values. In order to compare the efficacy of the two approaches namely, MFDFA and Lacunarity, in distinguishing between pre-cancerous tissues of various grades, we test these techniques on a set of 2-dimensional theoretical random multifractal fields. MFDFA is employed for computing the width of the singularity spectrum f(α), which is a measure of multifractal behavior. A weighted mean of the log-transformed lacunarity values at different scales is employed for differentiating between patterns with the same correlation dimension but differences in texture. The two different techniques are then applied to images containing RI values of biopsy samples from human cervical tissues that were histo-pathologically characterized as grade-I and grade-II pre-cancerous cells. The results show that the two approaches are complementary to one another when it comes to multi-scale analysis of complex natural patterns manifested in the images of such pre-cancerous cells.

Science and Scientific Curiosity in Pre-school—The teacher's point of view

Science.gov (United States)

Spektor-Levy, Ornit; Kesner Baruch, Yael; Mevarech, Zemira

2013-09-01

Nowadays, early science education is well-accepted by researchers, education professionals and policy makers. Overall, teachers' attitudes and conceptions toward the science subject domain and science education influence their ways of teaching and engagement. However, there is a lack of research regarding factors that affect this engagement in pre-school years. The main assumption of this study is that teachers' attitudes regarding science in pre-school can shape children's engagement in science and develop their scientific curiosity. Therefore, the main objectives of this study are to investigate the attitudes of pre-school teachers toward engaging in science and to explore their views about the nature of curiosity: who is a curious child and how can a child's natural curiosity be fostered? An extensive survey was conducted among 146 pre-school teachers by employing both qualitative and quantitative approaches. Results indicate that most of the participants believe that scientific education should begin in early childhood; very young children can investigate and take part in a process of inquiry; and scientific activities in pre-school can influence children's long-term attitudes toward science. Despite these views, most participants felt they did not possess sufficient scientific knowledge. Furthermore, participants expressed diverse opinions when asked to identify what constitutes curiosity, how the curious child can be identified and how a child's curiosity can be fostered. The research findings carry significant implications regarding how to implement scientific activities in pre-school, and how to encourage pre-school teachers to engage children in scientific activities in a way that will nurture their natural curiosity.

Equivalence of two Fixed-Point Semantics for Definitional Higher-Order Logic Programs

Directory of Open Access Journals (Sweden)

Angelos Charalambidis

2015-09-01

Full Text Available Two distinct research approaches have been proposed for assigning a purely extensional semantics to higher-order logic programming. The former approach uses classical domain theoretic tools while the latter builds on a fixed-point construction defined on a syntactic instantiation of the source program. The relationships between these two approaches had not been investigated until now. In this paper we demonstrate that for a very broad class of programs, namely the class of definitional programs introduced by W. W. Wadge, the two approaches coincide (with respect to ground atoms that involve symbols of the program. On the other hand, we argue that if existential higher-order variables are allowed to appear in the bodies of program rules, the two approaches are in general different. The results of the paper contribute to a better understanding of the semantics of higher-order logic programming.

The objective of this study is to evaluate the practical usefulness of a scoring system using the 5-5-5 exacerbation grading scale for allergic conjunctivitis disease (ACD). Subjects were 103 patients with ACD including 40 patients with vernal keratoconjunctivitis (VKC), 20 patients with atopic keratoconjunctivitis (AKC), and 43 patients with allergic conjunctivitis (AC). The 5-5-5 exacerbation grading scale consists of the following 3 graded groups of clinical observations: the 100-point-grade group (100 points for each observation) includes active giant papillae, gelatinous infiltrates of the limbus, exfoliative epithelial keratopathy, shield ulcer and papillary proliferation at lower palpebral conjunctiva; the 10-point-grade group (10 points for each observation) includes blepharitis, papillary proliferation with velvety appearance, Horner-Trantas spots, edema of bulbal conjunctiva, and superficial punctate keratopathy; and the 1-point-grade group (1 point for each observation) includes papillae at upper palpebral conjunctiva, follicular lesion at lower palpebral conjunctiva, hyperemia of palpebral conjunctiva, hyperemia of bulbal conjunctiva, and lacrimal effusion. The total points in each grade group were determined as the severity score of the 5-5-5 exacerbation grading scale. The median severity scores of the 5-5-5 exacerbation grading scale in VKC, AKC and AC were 243 (range: 12-444), 32.5 (11-344), and 13 (2-33), respectively. The severity score of each ACD disease type was significantly different (P Kruskal-Wallis test). The severity of each type of ACD was classified as severe, moderate, or mild according to the severity score. The 5-5-5 exacerbation grading scale is a useful clinical tool for grading the severity of each type of ACD.

Full Text Available Objectives: Surgical resection of low-grade gliomas (LGGs in eloquent areas is one of the challenges in neurosurgery, using assistant tools to facilitate effective excision with minimal postoperative neurological deficits has been previously discussed (awake craniotomy and intraoperative cortical stimulation; however, these tools could have their own limitations thus implementation of a simple and effective technique that can guide to safe excision is needed in many situations. Materials and Methods: The authors conducted a retrospective analysis of a prospectively collected data of 76 consecutive surgical cases of LGGs of these 21 cases were situated in eloquent areas. Preoperative functional magnetic resonance imaging (fMRI, pre- and post-operative MRI with volumetric analysis of the tumor size was conducted, and intraoperative determination of the craniometric points related to the tumor (navigation guided in 10 cases were studied to evaluate the effectiveness of the aforementioned tools in safe excision of the aforementioned tumors. Results: Total-near total excision in 14 (66.67% subtotal in 6 (28.57%, and biopsy in 1 case (4.57%. In long-term follow–up, only one case experienced persistent dysphasia. Conclusion: In spite of its simplicity, the identification of the safe anatomical landmarks guided by the preoperative fMRI is a useful technique that serves in safe excision of LGGs in eloquent areas. Such technique can replace intraoperative evoked potentials or the awake craniotomy in most of the cases. However, navigation-guided excision might be crucial in deeply seated and large tumors to allow safe and radical excision.

Point efficiency of the notion in multi objective programming

International Nuclear Information System (INIS)

Kampempe, B.J.D.; Manya, N.L.

2010-01-01

The approaches to the problem of multi-objective linear programming stochastic (PLMS) which have been proposed so far in the literature are not really satisfactory (9,11), so we want, in this article, to approach the problem of PLMS using the concept of efficiency point. It is also necessary to define what is meant by efficiency point in the context of PLMS. This is precisely the purpose of this article. In fact, it seeks to provide specific definitions of effective solutions that are not only mathematically consistent, but also have significance to a decision maker faced with such a decision problem. As a result, we have to use the concept of dominance in the time of PLMS, in the context where one has ordinal preference but no utility functions. In this paper, we propose to further explore the concepts of dominance and efficiency point. Indeed, the whole point P effective solutions are usually very broad and as we shall see, it can be identical to X. Accordingly, we will try to relax the definition of dominance relation >p in order to obtain other types of dominance point less demanding and generating subsets may be more effective especially interesting for a decision maker. We shall have to distinguish two other families of dominance relations point : the dominance and dominance scenario test, and within sets of efficient solutions proposed by these last two relations, we will focus on subsets of efficient solutions called sponsored and unanimous. We will study the properties of these various relationships and the possible links between the different effective resulting sets in order to find them and to calculate them explicitly. Finally we will establish some connections between different notions of efficiency and timely concept of Pareto-efficient solution on the deterministic case (PLMD)

Schilling, Elizabeth A; Aseltine, Robert H; James, Amy

2016-02-01

This study replicated and extended previous evaluations of the Signs of Suicide (SOS) prevention program in a high school population using a more rigorous pre-test post-test randomized control design than used in previous SOS evaluations in high schools (Aseltine and DeMartino 2004; Aseltine et al. 2007). SOS was presented to an ethnically diverse group of ninth grade students in technical high schools in Connecticut. After controlling for the pre-test reports of suicide behaviors, exposure to the SOS program was associated with significantly fewer self-reported suicide attempts in the 3 months following the program. Ninth grade students in the intervention group were approximately 64% less likely to report a suicide attempt in the past 3 months compared with students in the control group. Similarly, exposure to the SOS program resulted in greater knowledge of depression and suicide and more favorable attitudes toward (1) intervening with friends who may be exhibiting signs of suicidal intent and (2) getting help for themselves if they were depressed or suicidal. In addition, high-risk SOS participants, defined as those with a lifetime history of suicide attempt, were significantly less likely to report planning a suicide in the 3 months following the program compared to lower-risk participants. Differential attrition is the most serious limitation of the study; participants in the intervention group who reported a suicide attempt in the previous 3 months at baseline were more likely to be missing at post-test than their counterparts in the control group.

To retrospectively evaluate the relationship between T2 values of pre- and post-contrast magnetic resonance (MR) images of femoral cartilage in patients with varying degrees of osteoarthritis. A total of 19 patients underwent delayed gadolinium-enhanced MRI of cartilage. Six regions of interest for T2 value measurement were obtained from pre- and post-contrast T2-weighted, sagittal, multi-slice, multi-echo, source images in each subject. Regions with modified Noyes classification grade 2B and 3 were excluded. Comparison of T2 values between pre- and post-contrast images and T2 values among regions with the grade 0, 1 and 2A groups were statistically analyzed. Of a total of 114 regions, 79 regions showing grade 0 (n = 46), 1 (n = 18), or 2A (n = 15) were analyzed. The overall and individual T2 values of post-contrast images were significantly lower than those of pre-contrast images (overall, 35.3 ± 9.2 [mean ± SD] vs. 29.9 ± 8.2, p < 0.01; range of individual, 28.9-37.6 vs. 27.1-36.4, p < 0.01). Pearson correlation coefficients showed a strong positive correlation between pre- and post-contrast images (rho-Pearson = 0.712-0.905). T2 values of pre- and post-contrast images of the grade 0 group were significantly lower than those of the grade 1/2A group (pre T2, p = 0.003; post T2, p = 0.006). T2 values of the femoral cartilage of the knee joint are significantly lower on post-contrast images than on pre-contrast images. Furthermore, these T2 values have a strong positive correlation between pre- and post-contrast images.

If presented with serious mental illness (SMI), individuals' low help-seeking behaviors and poor adherence to treatment are associated with negative stereotypes and attitudes of healthcare providers. In this study, we examined the effects of a brief psychoeducational program on reducing stigma in pre-clinical medical students. One hundred and two pre-clinical medical students (20-23 years old) were randomly assigned to face-to-face contact + educational lecture (n = 51) condition or video-based contact + educational lecture (n = 51) condition. Measures of pre-clinical medical students' mental illness-related stigma using the Opening Minds Stigma Scale for Health Care Providers (OMS-HC) were administered at pre-, post-treatment, and 1-month follow-up. A 2 (condition: face-to-face contact + educational lecture, video-based contact + educational lecture) by 3 (time: pre-treatment, post-treatment, and 1-month follow-up) mixed model MANOVA was conducted on the Attitudes, Disclosure and Help-Seeking, and Social Distance OMS-HC subscales. Participants' scores on all subscales changed significantly across time, regardless of conditions. To determine how participants' scores changed significantly over time on each subscale, Bonferroni follow-up comparisons were performed to access pairwise differences for the main effect of time. Specifically, pairwise comparisons produced a significant reduction in Social Distance subscale between pre-treatment and post-treatment and between pre-treatment and 1-month follow-up, and a significant increase between post-treatment and 1-month follow-up, regardless of conditions. With respect to the Attitudes and Disclosure and Help-Seeking subscales, pairwise comparisons produced a significant reduction in scores between pre-treatment and post-treatment and a significant increase between post-treatment and 1-month follow-up. Our findings provide additional evidence that educational lecture on mental illness, coupled

The weight function method is described to analyze the crack growth behavior in functionally graded materials and in particular materials with a rising crack growth resistance curve. Further, failure of graded thermal barrier coatings (TBCs) under cyclic surface heating by laser irradiation is modeled on the basis of fracture mechanics. The damage of both graded and non-graded TBCs is found to develop in several distinct stages: vertical cracking→delamination→blistering→spalling. This sequence can be understood as an effect of progressive shrinkage due to sintering and high-temperature creep during thermal cycling, which increases the energy-release rate for vertical cracks which subsequently turn into delamination cracks. The results of finite element modeling, taking into account the TBC damage mechanisms, are compatible with experimental data. An increase of interface fracture toughness due to grading and a decrease due to ageing have been measured in a four-point bending test modified by a stiffening layer. Correlation with the damage observed in cyclic heating is discussed. It is explained in which way grading is able to reduce the damage

Full Text Available Aim: We retrospectively reviewed videourodynamic outcomes in children with primary vesicoureteral reflux. The aim of this study to evaluate the relationship between vesicoureteral reflux grade and bladder compliance. Material and Method: Videourodynamic traces of 53 children with primary vesicoureteral reflux investigated between January 2004 and January 2012 were reviewed. The detrusor pressures of the point when the reflux started were recorded. The detrusor pressures 10 cmH2O or less at that point was accepted as normal compliance (Group 1, the detrusor pressures more than10 cm H2O was accepted as hipocompliance (Group 2. The reflux grades were divided into two grades, low-grade reflux (grades 1 and 2, high-grade reflux (grades 3, 4 and 5. Data were analyzed using the chi-square test. Results: Patients’ ages ranged between 5 and 11 years (mean 7.09±1.81 years. Of the 53 patients, 29 (54.7% had normal compliance (Group 1, 24 (45.3% had hipocompliance (Group 2. Twenty-four (82.8% patients in-group 1 had a low-grade reflux, 5 (17.2% patients had a high-grade reflux. In group 2, 8 (33.3% patients had a low-grade reflux, 16 (66.7% patients had a high-grade reflux. The detected high-grade reflux in-group 2 was significantly higher than in-group 1 (p<0.001. Discussion: The physicians should be considering the bladder compliance at the point when the reflux started in primary vesicoureteral reflux cases. The bladder hipocompliance may play a secondary role in reflux grade.

Accounting for professionalism: an innovative point system to assess resident professionalism

Directory of Open Access Journals (Sweden)

Gary L. Malakoff

2014-04-01

Full Text Available Background: Professionalism is a core competency for residency required by the Accreditation Council of Graduate Medical Education. We sought a means to objectively assess professionalism among internal medicine and transitional year residents. Innovation: We established a point system to document unprofessional behaviors demonstrated by internal medicine and transitional year residents along with opportunities to redeem such negative points by deliberate positive professional acts. The intent of the policy is to assist residents in becoming aware of what constitutes unprofessional behavior and to provide opportunities for remediation by accruing positive points. A committee of core faculty and department leadership including the program director and clinic nurse manager determines professionalism points assigned. Negative points might be awarded for tardiness to mandatory or volunteered for events without a valid excuse, late evaluations or other paperwork required by the department, non-attendance at meetings prepaid by the department, and inappropriate use of personal days or leave. Examples of actions through which positive points can be gained to erase negative points include delivery of a mentored pre-conference talk, noon conference, medical student case/shelf review session, or a written reflection. Results: Between 2009 and 2012, 83 residents have trained in our program. Seventeen categorical internal medicine and two transitional year residents have been assigned points. A total of 55 negative points have been assigned and 19 points have been remediated. There appears to be a trend of fewer negative points and more positive points being assigned over each of the past three academic years. Conclusion: Commitment to personal professional behavior is a lifelong process that residents must commit to during their training. A professionalism policy, which employs a point system, has been instituted in our programs and may be a novel tool to

Size-dependent axisymmetric vibration of functionally graded circular plates in bifurcation/limit point instability

Science.gov (United States)

Ashoori, A. R.; Vanini, S. A. Sadough; Salari, E.

2017-04-01

In the present paper, vibration behavior of size-dependent functionally graded (FG) circular microplates subjected to thermal loading are carried out in pre/post-buckling of bifurcation/limit-load instability for the first time. Two kinds of frequently used thermal loading, i.e., uniform temperature rise and heat conduction across the thickness direction are considered. Thermo-mechanical material properties of FG plate are supposed to vary smoothly and continuously throughout the thickness based on power law model. Modified couple stress theory is exploited to describe the size dependency of microplate. The nonlinear governing equations of motion and associated boundary conditions are extracted through generalized form of Hamilton's principle and von-Karman geometric nonlinearity for the vibration analysis of circular FG plates including size effects. Ritz finite element method is then employed to construct the matrix representation of governing equations which are solved by two different strategies including Newton-Raphson scheme and cylindrical arc-length method. Moreover, in the following a parametric study is accompanied to examine the effects of the several parameters such as material length scale parameter, temperature distributions, type of buckling, thickness to radius ratio, boundary conditions and power law index on the dimensionless frequency of post-buckled/snapped size-dependent FG plates in detail. It is found that the material length scale parameter and thermal loading have a significant effect on vibration characteristics of size-dependent circular FG plates.

Rosch, F.

1995-01-01

In the mid-1980s, the Nuclear Regulatory Industry (NRC) began inspecting utility practices of procuring and dedicating commercial grade items intended for plant safety-related applications. As a result of the industry efforts to address NRC concerns, nuclear utilities have enhanced existing programs and procedures for dedication of commercial grade items. Though these programs were originally enhanced to meet NRC concerns, utilities have discovered that the dedication of commercial grade items can also reduce overall procurement costs. This paper will discuss the enhancement of utility dedication programs and demonstrates how utilities have utilized them to reduce procurement costs

Full Text Available This study is conducted to determine the effects of group counseling program on elementary school 8th grade students’ assertiveness skills. Study group was formed of 100 students getting educated in Erzurum Kültür Elementary School in 2011-2012 education years. RAE-Rathus Assertiveness Schedule was applied on this group to gather data. 30 students getting lower scores from the inventory have been randomly divided into experimental and control groups. Each group is formed of 15 students. Group counseling program has been carried out for 8 weeks on the experimental group to improve the students’ assertiveness skills. Single-way and two-way analysis of covariance (ANCOVA has been used in the analysis of the data. The data is analyzed with SPSS 19.00. The results of the study show that assertiveness skills of the students who participate in the group counseling program has increased significantly compared to the control group and to the preexperimental circumstances. Besides, it is determined that the change observed in the experimental group has been occurred separately from the age and socio-economic level variables, and it is determined with the monitoring test applied after four months that this affect is continued. According to this result, it can be said that the applied group counseling program is an effective means to improve the assertiveness skills of elementary school students

We implement the edit distance for marked point processes [Suzuki et al., Int. J. Bifurcation Chaos 20, 3699–3708 (2010)] as a binary integer program. Compared with the previous implementation using minimum cost perfect matching, the proposed implementation has two advantages: first, by using the proposed implementation, we can apply a wide variety of software and hardware, even spin glasses and coherent ising machines, to calculate the edit distance for marked point processes; second, the proposed implementation runs faster than the previous implementation when the difference between the numbers of events in two time windows for a marked point process is large.

Full Text Available The current focus on assessing “college and career readiness” raises an empirical question: How do high school tests compare with college admissions tests in predicting performance in college? We explored this using data from the City University of New York and public colleges in Kentucky. These two systems differ in the choice of college admissions test, the stakes for students on the high school test, and demographics. We predicted freshman grade point average (FGPA from high school GPA and both college admissions and high school tests in mathematics and English. In both systems, the choice of tests had only trivial effects on the aggregate prediction of FGPA. Adding either test to an equation that included the other had only trivial effects on prediction. Although the findings suggest that the choice of test might advantage or disadvantage different students, it had no substantial effect on the over- and underprediction of FGPA for students classified by race-ethnicity or poverty.

Abstract The rhythm of breathing in mammals, originating within the brainstem pre-Bötzinger complex (pre-BötC), is presumed to be generated by glutamatergic neurons, but this has not been directly demonstrated. Additionally, developmental expression of the transcription factor Dbx1 or expression of the neuropeptide somatostatin (Sst), has been proposed as a marker for the rhythmogenic pre-BötC glutamatergic neurons, but it is unknown whether these other two phenotypically defined neuronal populations are functionally equivalent to glutamatergic neurons with regard to rhythm generation. To address these problems, we comparatively investigated, by optogenetic approaches, the roles of pre-BötC glutamatergic, Dbx1-derived, and Sst-expressing neurons in respiratory rhythm generation in neonatal transgenic mouse medullary slices in vitro and also more intact adult perfused brainstem-spinal cord preparations in situ. We established three different triple-transgenic mouse lines with Cre-driven Archaerhodopsin-3 (Arch) expression selectively in glutamatergic, Dbx1-derived, or Sst-expressing neurons for targeted photoinhibition. In each line, we identified subpopulations of rhythmically active, Arch-expressing pre-BötC inspiratory neurons by whole-cell recordings in medullary slice preparations in vitro, and established that Arch-mediated hyperpolarization of these inspiratory neurons was laser power dependent with equal efficacy. By site- and population-specific graded photoinhibition, we then demonstrated that inspiratory frequency was reduced by each population with the same neuronal voltage-dependent frequency control mechanism in each state of the respiratory network examined. We infer that enough of the rhythmogenic pre-BötC glutamatergic neurons also have the Dbx1 and Sst expression phenotypes, and thus all three phenotypes share the same voltage-dependent frequency control property.

To investigate the interobserver reproducibility and diagnostic feasibility of a visual grading system for assessing atrophy of the supraspinatus muscle on magnetic resonance imaging (MRI). Three independent radiologists retrospectively evaluated the occupying ratio of the supraspinatus muscle in the supraspinatus fossa on 192 shoulder MRI examinations in 188 patients using a 3-point visual grading system (1, ≥ 60%; 2, 30-59%; 3, < 30%) on oblique sagittal T1-weighted images. The inter-reader agreement and the agreement with the reference standard (3-point grades according to absolute occupying ratio values quantitatively measured by directly contouring the muscles on MRI) were analyzed using weighted kappa. The visual grading was applied by a single reader to a group of 100 consecutive patients who had undergone rotator cuff repair to retrospectively determine the association between the visual grades at preoperative state and postsurgical occurrences of retear. The inter-reader weighted kappa value for the visual grading was 0.74 when averaged across three reader pairs (0.70-0.77 for individual reader pairs). The weighted kappa value between the visual grading and the reference standard ranged from 0.75 to 0.83. There was a significant difference in retear rates of the rotator cuff between the 3 visual grades of supraspinatus muscle atrophy on MRI in univariable analysis (p < 0.001), but not in multivariable analysis (p = 0.026). The 3-point visual grading system may be a feasible method to assess the severity of supraspinatus muscle atrophy on MRI and assist in the clinical management of patients with rotator cuff tear.

Role of the pre- and post-natal environment in developmental programming of health and productivity.

Reynolds, Lawrence P; Caton, Joel S

2012-05-06

The concept that developmental insults (for example, poor pre- or postnatal nutrition) can have long-term consequences on health and well-being of the offspring has been termed developmental programming. In livestock, developmental programming affects production traits, including growth, body composition, and reproduction. Although low birth weight was used as a proxy for compromised fetal development in the initial epidemiological studies, based on controlled studies using livestock and other animal models in the last two decades we now know that developmental programming can occur independently of any effects on birth weight. Studies in humans, rodents, and livestock also have confirmed the critical role of the placenta in developmental programming. In addition, the central role of epigenetic regulation in developmental programming has been confirmed. Lastly, relatively simple therapeutic/management strategies designed to 'rescue' placental development and function are being developed to minimize the effects of developmental programming on health and productivity of humans, livestock, and other mammals.

The Next Generation Science Standards (NGSS) are more inclusive of ocean sciences than the National Science Standards and respective state science standards. In response, the Center for Ocean Sciences Education Excellence-SouthEast (COSEE SE) is piloting the South Carolina's Amazing Coast (SCAC) program: a three-year initiative that incorporates ocean science concepts in grades 3-5 with the goals of addressing NGSS, STEM (science-technology-engineering-math) disciplines, and inquiry skills. The SCAC program targeted two Charleston County, South Carolina elementary schools that were demographically similar: Title 1 status (75% free or reduced lunch), > 90% African American student population, grade level size inquiry skills. Specifically, third grade students learn about coastal habitats, animal and plant adaptations, and human impacts to the environment, and engage in a salt marsh restoration capstone project. This part of the curriculum aligns with the NGSS Core Ideas 3-LS1, 3-LS3, 3-LS4, 3-ESS3. The fourth grade students learn about weather, organism responses to the environment, and engage in a weather buoy construction capstone project. This part of the curriculum aligns with the NGSSS Core Ideas 4-LS1, 4-ESS2, 4-ESS3, 3-5-ETS1. In 5th grade, students focus specifically on the ocean ecosystem, human impacts on the environment and engage in a capstone project of designing and constructing remotely operated vehicles. This part of the curriculum aligns with NGSS Core Ideas 5-PS2, 5-LS1, 5-LS2, 5-ESS2, 3-5-ETS1. Initial evaluation results indicate that the SCAC teachers value the coach mentor approach for teacher professional development as well as the impact of field based experiences, place-based learning, and a culminating capstone project on student learning. Teacher feedback also indicates elements of sustainability that extend beyond the scope of the pilot project.These initial evaluation results poise the SCAC curriculum to be replicated in other

Gliomas are the most common intra-axial primary brain tumour; therefore, predicting glioma grade would influence therapeutic strategies. Although several methods based on single or multiple parameters from diagnostic images exist, a definitive method for pre-operatively determining glioma grade remains unknown. We aimed to develop an unsupervised method using multiple parameters from pre-operative diffusion tensor images for obtaining a clustered image that could enable visual grading of gliomas. Fourteen patients with low-grade gliomas and 19 with high-grade gliomas underwent diffusion tensor imaging and three-dimensional T1-weighted magnetic resonance imaging before tumour resection. Seven features including diffusion-weighted imaging, fractional anisotropy, first eigenvalue, second eigenvalue, third eigenvalue, mean diffusivity and raw T2 signal with no diffusion weighting, were extracted as multiple parameters from diffusion tensor imaging. We developed a two-level clustering approach for a self-organizing map followed by the K-means algorithm to enable unsupervised clustering of a large number of input vectors with the seven features for the whole brain. The vectors were grouped by the self-organizing map as protoclusters, which were classified into the smaller number of clusters by K-means to make a voxel-based diffusion tensor-based clustered image. Furthermore, we also determined if the diffusion tensor-based clustered image was really helpful for predicting pre-operative glioma grade in a supervised manner. The ratio of each class in the diffusion tensor-based clustered images was calculated from the regions of interest manually traced on the diffusion tensor imaging space, and the common logarithmic ratio scales were calculated. We then applied support vector machine as a classifier for distinguishing between low- and high-grade gliomas. Consequently, the sensitivity, specificity, accuracy and area under the curve of receiver operating characteristic

Assessment of young learners in the pre-literacy period in Serbia

Full Text Available Given the fact that English is an obligatory subject in Serbian schools since the first grade, many parents opt for an early start and enroll their children in English classes while they are still in kindergarten, before they can actually read or write. Another context in which young learners learn English in Serbia are the first two grades of primary school, which are also considered to belong to the pre-literacy period because children learn the Latin alphabet only in the second semester of the second grade. For those reasons pupils in Serbia do not read or write in English until the age of 9, so the question is how the teacher can implement assessment in the pre-literacy period. Relying on informal interviews with 15 teachers, this paper intends to investigate how assessment is done with very young learners in the pre-literacy period in private and state-owned primary schools and to present a solution based on the competences that children in this age group already possess, as well as on the teaching and learning aspects which are of great value for the improvement of children's English language competence.

GRESS, FORTRAN Pre-compiler with Differentiation Enhancement

International Nuclear Information System (INIS)

1999-01-01

1 - Description of program or function: The GRESS FORTRAN pre-compiler (SYMG) and run-time library are used to enhance conventional FORTRAN-77 programs with analytic differentiation of arithmetic statements for automatic differentiation in either forward or reverse mode. GRESS 3.0 is functionally equivalent to GRESS 2.1. GRESS 2.1 is an improved and updated version of the previous released GRESS 1.1. Improvements in the implementation of a the CHAIN option have resulted in a 70 to 85% reduction in execution time and up to a 50% reduction in memory required for forward chaining applications. 2 - Method of solution: GRESS uses a pre-compiler to analyze FORTRAN statements and determine the mathematical operations embodied in them. As each arithmetic assignment statement in a program is analyzed, SYMG generates the partial derivatives of the term on the left with respect to each floating-point variable on the right. The result of the pre-compilation step is a new FORTRAN program that can produce derivatives for any REAL (i.e., single or double precision) variable calculated by the model. Consequently, GRESS enhances FORTRAN programs or subprograms by adding the calculation of derivatives along with the original output. Derivatives from a GRESS enhanced model can be used internally (e.g., iteration acceleration) or externally (e.g., sensitivity studies). By calling GRESS run-time routines, derivatives can be propagated through the code via the chain rule (referred to as the CHAIN option) or accumulated to create an adjoint matrix (referred to as the ADGEN option). A third option, GENSUB, makes it possible to process a subset of a program (i.e., a do loop, subroutine, function, a sequence of subroutines, or a whole program) for calculating derivatives of dependent variables with respect to independent variables. A code enhanced with the GENSUB option can use forward mode, reverse mode, or a hybrid of the two modes. 3 - Restrictions on the complexity of the problem: GRESS

Purpose of this research is to determine skills and abilities required for the “school readiness” according to the Grade 1 teachers and parents and reveal results of this situation related to pre-school education. This study was performed with 14 Grade 1 teachers who work in the private and public elementary schools of Konya city and with 13 parents. In research, semi-structured interview was used in order to get perspectives of participants about the phenomenon of readiness level of school that was consisted of open-ended questions. Raw data that were obtained through interviews have been analyzed by using descriptive analysis technique. According to the findings of research, Grade 1 teachers of elementary school described school readiness as “being matured to the ability required by the Grade 1 of elementary school” and stated that this maturity depends on parallel development of social, emotional, mental and physical aspects of child. Teachers also think that pre-school education must be compulsory for children to readily start school.

people in Korea take far more of interests in the nuclear power and whether they are well prepared in the lack of professional human resources in it in the foreseeable future. It is not only personal concern anymore, but also national concern. In particular, retirement of the experts in nuclear field is likely to lose our competitiveness in the world. It is urgent for the government and institutions in Korea to develop and implement educational programs to secure talented new workers in the field. This study analyzes the cases of development and application of pre-retirement education program of professional talent for nuclear R and D and then, develops programs to help nuclear experts retire. In the aging society, the retirement of nuclear experts is a national issue that can't be held off rather than each worker's problem. There are people at the heart of nuclear power. This is because they do all the things like nuclear research and development, and construction. Therefore, it is important to nurture and manage nuclear experts to ensure the sustainable development of nuclear with safety. This program could be also a part of it. KAERI is the organization that represents domestic nuclear research, and it is their urgent task to prepare for aging.

Full Text Available The aim of this study was to evaluate the impact of a community-based exercise program on bone mineral density and body composition in postmenopausal women with pre-diabetes and type 2 diabetes. Twenty postmenopausal women (aged 61.3 ± 6.0 years with pre-diabetes and type 2 diabetes were randomly assigned to a community-based exercise program group (n=10 or a control group (n=10. The community-based exercise program was multicomponent, three days per week for 32 weeks, and included walking, resistance and aquatic exercises. Body composition and bone mineral density were measured pre and post-training by dual X-ray absorptiometry. In the exercise group significant increases were found in the ward’s triangle bone mineral density (+7.8%, p=0.043, and in fat-free mass (+2.4%, p=0.018. The findings suggest that regular multicomponent training is effective in preventing osteoporosis and sarcopenia among postmenopausal women with pre-diabetes and type 2 diabetes.

Examination of Speed Contribution of Parallelization for Several Fingerprint Pre-Processing Algorithms

GORGUNOGLU, S.

2014-05-01

Full Text Available In analysis of minutiae based fingerprint systems, fingerprints needs to be pre-processed. The pre-processing is carried out to enhance the quality of the fingerprint and to obtain more accurate minutiae points. Reducing the pre-processing time is important for identification and verification in real time systems and especially for databases holding large fingerprints information. Parallel processing and parallel CPU computing can be considered as distribution of processes over multi core processor. This is done by using parallel programming techniques. Reducing the execution time is the main objective in parallel processing. In this study, pre-processing of minutiae based fingerprint system is implemented by parallel processing on multi core computers using OpenMP and on graphics processor using CUDA to improve execution time. The execution times and speedup ratios are compared with the one that of single core processor. The results show that by using parallel processing, execution time is substantially improved. The improvement ratios obtained for different pre-processing algorithms allowed us to make suggestions on the more suitable approaches for parallelization.

To evaluate and predict factors influencing prognosis and/or clinical outcome at 6 months in patients with spontaneous subarachnoid haemorrhage, World Federation of Neurosurgical Societies (WFNS) grades iv and v. This was a retrospective study of a consecutive series of 394 patients admitted to our hospital with clinical and radiological diagnosis of spontaneous subarachnoid haemorrhage, from 1 January 1999 to 30 June 2009. We selected 121 patients who met the criteria of being in WFNS grades iv or v before treatment; 3 patients were excluded due to loss of tracking. The outcome variable was assessed 6 months after the event using the Glasgow Outcome Scale. A P value<.05 was considered statistically significant. One hundred and twenty-one patients were included in the statistical analysis. The average age of the patients in the series was 54 years (14-92). Patients who had a mean Glasgow Coma Scale lower than 7 points (P<.0001), those who were grade v (P<.0001) in the pre-treatment WFNS scale and those with pupillary disorder (P=.002) had a worse clinical outcome. Likewise, those with associated intraparenchymal hematoma (P=.020) and those not receiving any treatment (P=.020) were also associated with a poor clinical outcome. These results were statistically significant. Patients admitted with a WFNS grade v and/or presenting pupil disorder and/or intraparenchymal hematoma were associated with worse clinical outcomes.

Disposition of excess weapon grade plutonium: Status of the Russian program

Energy Technology Data Exchange (ETDEWEB)

Diyakov, Anatoly [Center for Arms Control, Energy and Environmental Studies, Moscow (Russian Federation)

2015-07-01

During the Cold War, the Soviet Union and United States produced huge quantities of plutonium for weapons. Substantial cuts in their nuclear arsenals released of huge amounts of weapon grade nuclear materials. This put into the agenda the problem what to do with the excess weapon materials. In 2000 Russia and the United States concluded a Plutonium Management and Disposition Agreement (PMDA), committing each to eliminate 34 tons of excess weapon plutonium. It was expected that the implementation of the PMDA Agreement will start in the second half of the year 2009 and the disposition programs finalized in 2025. But from the very beginning the practical implementation of the PMDA agreement met with substantial difficulties. After the consultations held in 2006-2007 the PMDA Agreement was modified. In compliance with the modified Agreement each side pledged to start the disposition of 34 tons of excess plutonium (25 tons in the form of metal and 9 tons in dioxide) in 2018 and to finalize the process in 15 years. Both sides were supposed to use the same disposition method through use in the MOX fuel and its subsequent irradiation in civil nuclear reactors: in light reactors for the USA and in fast neutron reactors for Russia. The presentation is going to provide the current status of the disposition program.

2014-01-01

Anesthesiology residency programs will be expected to have Milestones-based evaluation systems in place by July 2014 as part of the Next Accreditation System. The San Antonio Uniformed Services Health Education Consortium (SAUSHEC) anesthesiology residency program developed and implemented a Milestones-based feedback and evaluation system a year ahead of schedule. It has been named the Milestone-specific, Observed Data points for Evaluating Levels of performance (MODEL) assessment strategy. The "MODEL Menu" and the "MODEL Blueprint" are tools that other anesthesiology residency programs can use in developing their own Milestones-based feedback and evaluation systems prior to ACGME-required implementation. Data from our early experience with the streamlined MODEL blueprint assessment strategy showed substantially improved faculty compliance with reporting requirements. The MODEL assessment strategy provides programs with a workable assessment method for residents, and important Milestones data points to programs for ACGME reporting.

2014-01-01

Poor implementation quality (IQ) is known to reduce program effects making it important to consider IQ for evaluation and dissemination of prevention programs. However, less is known about the ways specific implementation variables relate to outcomes. In this study, two versions of the keepin’ it REAL, 7th grade drug prevention intervention were implemented in 78 classrooms in 25 schools in rural districts in Pennsylvania and Ohio. IQ was measured through observational coding of 276 videos. IQ variables included adherence to the curriculum, teacher engagement (attentiveness, enthusiasm, seriousness, clarity, positivity), student engagement (attention, participation), and a global rating of teacher delivery quality. Factor analysis showed that teacher engagement, student engagement, and delivery quality formed one factor, which was labeled delivery. A second factor was adherence to the curriculum. Self-report student surveys measured substance use, norms (beliefs about prevalence and acceptability of use), and efficacy (beliefs about one’s ability to refuse substance offers) at two waves (pretest, immediate posttest). Mixed model regression analysis which accounted for missing data and controlled for pretest levels examined implementation quality’s effects on individual level outcomes, statistically controlling for cluster level effects. Results show that when implemented well, students show positive outcomes compared to students receiving a poorly implemented program. Delivery significantly influenced substance use and norms, but not efficacy. Adherence marginally significantly predicted use and significantly predicted norms, but not efficacy. Findings underscore the importance of comprehensively measuring and accounting for IQ, particularly delivery, when evaluating prevention interventions. PMID:24442403

However, these categories are not distinctly defined, and are often used arbitrarily. Instruments for pain assessment use more sophisticated scales, such as a 0–10 numerical rating scale, and apart from pain intensity assess pain-related interference and disability. The aim of the study was to identify cutoff points for mild, moderate, and severe nondental orofacial pain using a numerical rating scale, a pain-related interference scale, and a disability measurement. Materials and methods: A total of 245 patients referred to the Facial Pain Unit in London were included in the study. Intensity and pain-related interference were assessed by the Brief Pain Inventory. Pain-related disability was assessed by the Chronic Graded Pain Scale. Average pain intensity (0–10 was classified into nine schemes with varying cutoff points of mild, moderate, and severe pain. The scheme with the most significant intergroup difference, expressed by multivariate analysis of variance, provided the cutoffs between mild, moderate, and severe pain. Results: The combination that showed the greatest intergroup differences for all patients was scheme 47 (mild 1–4, moderate 5–7, severe 8–10. The same combination provided the greatest intergroup differences in subgroups of patients with temporomandibular disorder and chronic idiopathic facial pain, respectively. Among the trigeminal neuralgia patients alone, the combination with the highest intergroup differences was scheme 48 (mild 1–4, moderate 5–8, severe 9–10. Conclusion: The cutoff points established in

Purpose: The clinical management of meningioma is guided by its grade and biologic behavior. Currently, diagnosis of tumor grade follows surgical resection and histopathologic review. Reliable techniques for pre-operative determination of tumor behavior are needed. We investigated the association between imaging features extracted from preoperative gadolinium-enhanced T1-weighted MRI and meningioma grade. Methods: We retrospectively examined the pre-operative MRI for 139 patients with de novo WHO grade I (63%) and grade II (37%) meningiomas. We investigated the predictive power of ten semantic radiologic features as determined by a neuroradiologist, fifteen radiomic features, and tumor location. Conventional (volume and diameter) imaging features were added for comparison. AUC was computed for continuous and χ 2 for discrete variables. Classification was done using random forest. Performance was evaluated using cross validation (1000 iterations, 75% training and 25% validation). All p-values were adjusted for multiple testing. Results: Significant association was observed between meningioma grade and tumor location (p<0.001) and two semantic features including intra-tumoral heterogeneity (p<0.001) and overt hemorrhage (p=0.01). Conventional (AUC 0.61–0.67) and eleven radiomic (AUC 0.60–0.70) features were significant from random (p<0.05, Noether test). Median AUC values for classification of tumor grade were 0.57, 0.71, 0.72 and 0.77 respectively for conventional, radiomic, location, and semantic features after using random forest. By combining all imaging data (semantic, radiomic, and location), the median AUC was 0.81, which offers superior predicting power to that of conventional imaging descriptors for meningioma as well as radiomic features alone (p<0.05, permutation test). Conclusion: We demonstrate a strong association between radiologic features and meningioma grade. Pre-operative prediction of tumor behavior based on imaging features offers promise

Mendez, Ivar; Song, Michael; Chiasson, Paula; Bustamante, Luis

2013-01-01

The expansion of neuromodulation and its indications has resulted in hundreds of thousands of patients with implanted devices worldwide. Because all patients require programming, this growth has created a heavy burden on neuromodulation centers and patients. Remote point-of-care programming may provide patients with real-time access to neuromodulation expertise in their communities. To test the feasibility of remotely programming a neuromodulation device using a remote-presence robot and to determine the ability of an expert programmer to telementor a nonexpert in programming the device. A remote-presence robot (RP-7) was used for remote programming. Twenty patients were randomly assigned to either conventional programming or a robotic session. The expert remotely mentored 10 nurses with no previous experience to program the devices of patients assigned to the remote-presence sessions. Accuracy of programming, adverse events, and satisfaction scores for all participants were assessed. There was no difference in the accuracy or clinical outcomes of programming between the standard and remote-presence sessions. No adverse events occurred in any session. The patients, nurses, and the expert programmer expressed high satisfaction scores with the remote-presence sessions. This study establishes the proof-of-principle that remote programming of neuromodulation devices using telepresence and expert telementoring of an individual with no previous experience to accurately program a device is feasible. We envision a time in the future when patients with implanted devices will have real-time access to neuromodulation expertise from the comfort of their own home.

Full Text Available In Korea, a national university admission is made based on a variety of factors like Grade Point Average(GPA, Statement of Purpose(SOP, Letters of Recommendation, as well as other achievement records and/or descriptions of specific qualifications. In reviewing applications, the admissions committee considers GPA, SOP, recommendation letters and other factors are also taken into consideration in the interview process. An interview test is designed to measure the overall ability of pre-service teachers, particularly focusing on their character and nature. Thus, the purpose of this study is intended to understand the admission processes of a national university in Korea, and to design the interview test questions to choose the ideal pre-service teachers who are to work in the public elementary school after graduation. In order to answer this question, a survey questionnaire was distributed to 478 college students and then results were collected and analysed.

Image subsampling and point scoring approaches for large-scale marine benthic monitoring programs

Science.gov (United States)

Perkins, Nicholas R.; Foster, Scott D.; Hill, Nicole A.; Barrett, Neville S.

2016-07-01

Benthic imagery is an effective tool for quantitative description of ecologically and economically important benthic habitats and biota. The recent development of autonomous underwater vehicles (AUVs) allows surveying of spatial scales that were previously unfeasible. However, an AUV collects a large number of images, the scoring of which is time and labour intensive. There is a need to optimise the way that subsamples of imagery are chosen and scored to gain meaningful inferences for ecological monitoring studies. We examine the trade-off between the number of images selected within transects and the number of random points scored within images on the percent cover of target biota, the typical output of such monitoring programs. We also investigate the efficacy of various image selection approaches, such as systematic or random, on the bias and precision of cover estimates. We use simulated biotas that have varying size, abundance and distributional patterns. We find that a relatively small sampling effort is required to minimise bias. An increased precision for groups that are likely to be the focus of monitoring programs is best gained through increasing the number of images sampled rather than the number of points scored within images. For rare species, sampling using point count approaches is unlikely to provide sufficient precision, and alternative sampling approaches may need to be employed. The approach by which images are selected (simple random sampling, regularly spaced etc.) had no discernible effect on mean and variance estimates, regardless of the distributional pattern of biota. Field validation of our findings is provided through Monte Carlo resampling analysis of a previously scored benthic survey from temperate waters. We show that point count sampling approaches are capable of providing relatively precise cover estimates for candidate groups that are not overly rare. The amount of sampling required, in terms of both the number of images and

[Effectiveness and difficulty of education on nosocomial infection control for pre-clinical practice in the clinic, so-called inclusive clinical practice phase I, for students in the Faculty of Dentistry, Tokyo Medical and Dental University].

It has been planned to give pre-clinical practice in the clinic, so-called inclusive clinical practice phase I, for fifth-grade students in the School of Dentistry, Faculty of Dentistry, Tokyo Medical and Dental University, to give them the clinical training needed to perform dental practice and clinical practicum for comprehensive patient care, namely inclusive clinical practice phase II. This study analyzed the educative efficiency of the class on nosocomial infection control (NIC) by comparing achievements pre- and post-test, and discussed appropriate education planning on the NIC for dental students. Sixty-two fifth-grade students in the 2007 academic year sat the pre- and post-tests; the mean score and standard deviation of these tests were 5.30 +/- 1.26 (n = 56) and 8.59 +/- 1.18 (n = 59), respectively. There was a statistically significant difference between them (paired t-test, p < 0.01). Another finding was that students with high scores in the post-test did not necessarily achieve high ratings in the pre-test. It is suggested that the introduction of pre- and post-tests and the clarification of main points in the class as a theme of NIC could be a useful tool for increasing the comprehension of students on the theme. Since students at lower grades will attend clinical practice in the university hospital, it is thought that students should be given NIC training early in the clinical course, and the current curriculum should be improved to increase the opportunity for students to study this important issue.

Finite element and node point generation computer programs used for the design of toroidal field coils in tokamak fusion devices

International Nuclear Information System (INIS)

Smith, R.A.

1975-06-01

The structural analysis of toroidal field coils in Tokamak fusion machines can be performed with the finite element method. This technique has been employed for design evaluations of toroidal field coils on the Princeton Large Torus (PLT), the Poloidal Diverter Experiment (PDX), and the Tokamak Fusion Test Reactor (TFTR). The application of the finite element method can be simplified with computer programs that are used to generate the input data for the finite element code. There are three areas of data input where significant automation can be provided by supplementary computer codes. These concern the definition of geometry by a node point mesh, the definition of the finite elements from the geometric node points, and the definition of the node point force/displacement boundary conditions. The node point forces in a model of a toroidal field coil are computed from the vector cross product of the coil current and the magnetic field. The computer programs named PDXNODE and ELEMENT are described. The program PDXNODE generates the geometric node points of a finite element model for a toroidal field coil. The program ELEMENT defines the finite elements of the model from the node points and from material property considerations. The program descriptions include input requirements, the output, the program logic, the methods of generating complex geometries with multiple runs, computational time and computer compatibility. The output format of PDXNODE and ELEMENT make them compatible with PDXFORC and two general purpose finite element computer codes: (ANSYS) the Engineering Analysis System written by the Swanson Analysis Systems, Inc., and (WECAN) the Westinghouse Electric Computer Analysis general purpose finite element program. The Fortran listings of PDXNODE and ELEMENT are provided

Inter-observer reproducibility before and after web-based education in the Gleason grading of the prostate adenocarcinoma among the Iranian pathologists.

Directory of Open Access Journals (Sweden)

Alireza Abdollahi

2014-05-01

Full Text Available This study was aimed at determining intra and inter-observer concordance rates in the Gleason scoring of prostatic adenocarcinoma, before and after a web-based educational course. In this self-controlled study, 150 tissue samples of prostatic adenocarcinoma are re-examined to be scored according to the Gleason scoring system. Then all pathologists attend a free web-based course. Afterwards, the same 150 samples [with different codes compared to the previous ones] are distributed differently among the pathologists to be assigned Gleason scores. After gathering the data, the concordance rate in the first and second reports of pathologists is determined. In the pre web-education, the mean kappa value of Interobserver agreement was 0.25 [fair agreement]. Post web-education significantly improved with the mean kappa value of 0.52 [moderate agreement]. Using weighted kappa values, significant improvement was observed in inter-observer agreement in higher scores of Gleason grade; Score 10 was achieved for the mean kappa value in post web-education was 0.68 [substantial agreement] compared to 0.25 (fair agreement in pre web-education. Web-based training courses are attractive to pathologists as they do not need to spend much time and money. Therefore, such training courses are strongly recommended for significant pathological issues including the grading of the prostate adenocarcinoma. Through web-based education, pathologists can exchange views and contribute to the rise in the level of reproducibility. Such programs need to be included in post-graduation programs.

A phenomenographic study of students' experiences with transition from pre-college engineering programs to first-year engineering

Science.gov (United States)

Salzman, Noah

Recent national dialogues on the importance of preparing more students for careers in Science, Technology, Engineering, and Mathematics has driven the development of formal and informal learning opportunities for children and adolescents to explore engineering. Despite the growth of these programs, relatively little research exists on how participation in these programs affects students who choose to pursue further study in engineering. The present study addressed this gap through an exploration of the different ways that First-Year Engineering students experience the transition from pre-college engineering to undergraduate engineering studies. Given the focus of this research on students' experiences, phenomenography was chosen to explore the phenomenon of transition from pre-college to first-year engineering at a large, public Midwestern university. This facilitated understanding the range of variation in the ways that students experienced this transition. Twenty-two students with different amounts of participation in a variety of different engineering programs were selected to be interviewed using a purposeful maximum variation sampling strategy. The interviews were guided by a semi-structured interview protocol that encouraged the participants to reflect on their pre-college engineering experiences, their experiences in First-Year Engineering, and the transition between the two domains. The interviews were analyzed using phenomenographic methods to develop an outcome space consisting of five qualitatively different but related ways of experiencing the transition from pre-college to First-Year Engineering. These categories of description included Foreclosure, Frustration, Tedium, Connection, and Engaging Others. With the exception of the first category which was characterized by a lack of passion and commitment to engineering, the remaining four categories formed a hierarchical relationship representing increasing integration in First-Year Engineering.

In the mid-1990s, New Brunswick Power Nuclear implemented a Management System Process Model at the Point Lepreau Generating Station that provides the basic elements of a knowledge management program. As noted by the IAEA, the challenge facing the nuclear industry now is to make improvements in knowledge management in areas that are more difficult to implement. Two of these areas are: increasing the value of existing knowledge, and converting tacit knowledge to explicit knowledge (knowledge acquisition). This paper describes some practical examples of knowledge management improvements in the Point Lepreau heat transport system ageing management program. (author)

Full Text Available This study investigates U.S. elementary (kindergarten-Grade 6, ages 5-12 pre- and in-service teachers’ discussions of informational texts to understand current practices and identify needs with respect to how teachers support students in building knowledge from complex informational text as specified in the grade-level expectations of the Common Core State Standards adopted in many U.S. states. Transcripts and reflections from 17 in-service and 31 pre-service teachers’ informational text discussions were analyzed for teachers’ focus on the text, background knowledge, and text/background knowledge. In addition, transcripts were analyzed for the types of text ideas teachers targeted (details/main ideas, the comprehension demands placed on students, how teachers used follow-up moves to encourage higher level thinking, and how teachers use transcripts of their discussions to analyze and critique their own practice. Findings suggest that both pre- and in-service teachers draw heavily on students’ background knowledge and text details in their questioning; but differences exist in how pre- and in-service teachers use follow-up responses to promote knowledge building. Findings also suggest that both pre- and in-service teachers can use their transcripts to recognize areas of need, and offer themselves suggestions to better support students’ understanding. Implications are offered for teacher education and professional development.

Concept of exponential mass variation of oscillators along the chain length of N oscillators is proposed in the present Letter. The temperature profile and thermal conductivity of one-dimensional (1D) exponential mass graded harmonic and anharmonic lattices are studied on the basis of Fermi–Pasta–Ulam (FPU) β model. Present findings conclude that the exponential mass graded chain provide higher conductivity than that of linear mass graded chain. The exponential mass graded anharmonic chain generates the thermal rectification of 70–75% which is better than linear mass graded materials, so far. Thus instead of using linear mass graded material, the use of exponential mass graded material will be a better and genuine choice for controlling the heat flow at nano-scale. -- Highlights: ► In PRE 82 (2010) 040101, use of mass graded material as a thermal devices is explored. ► Concept of exponential mass graded material is proposed. ► The rectification obtained is about 70–75% which is better than linear mass graded materials. ► The exponential mass graded material will be a better choice for the thermal devices at nano-scale.

The thermal expansion of gold: point defect concentrations and pre-melting in a face-centred cubic metal.

On the basis of ab initio computer simulations, pre-melting phenomena have been suggested to occur in the elastic properties of hexagonal close-packed iron under the conditions of the Earth's inner core just before melting. The extent to which these pre-melting effects might also occur in the physical properties of face-centred cubic metals has been investigated here under more experimentally accessible conditions for gold, allowing for comparison with future computer simulations of this material. The thermal expansion of gold has been determined by X-ray powder diffraction from 40 K up to the melting point (1337 K). For the entire temperature range investigated, the unit-cell volume can be represented in the following way: a second-order Grüneisen approximation to the zero-pressure volumetric equation of state, with the internal energy calculated via a Debye model, is used to represent the thermal expansion of the 'perfect crystal'. Gold shows a nonlinear increase in thermal expansion that departs from this Grüneisen-Debye model prior to melting, which is probably a result of the generation of point defects over a large range of temperatures, beginning at T / T m > 0.75 (a similar homologous T to where softening has been observed in the elastic moduli of Au). Therefore, the thermodynamic theory of point defects was used to include the additional volume of the vacancies at high temperatures ('real crystal'), resulting in the following fitted parameters: Q = ( V 0 K 0 )/γ = 4.04 (1) × 10 -18  J, V 0 = 67.1671 (3) Å 3 , b = ( K 0 ' - 1)/2 = 3.84 (9), θ D = 182 (2) K, ( v f /Ω)exp( s f / k B ) = 1.8 (23) and h f = 0.9 (2) eV, where V 0 is the unit-cell volume at 0 K, K 0 and K 0 ' are the isothermal incompressibility and its first derivative with respect to pressure (evaluated at zero pressure), γ is a Grüneisen parameter, θ D is the Debye temperature, v f , h f and s f are the vacancy formation volume, enthalpy and entropy

Overview of Pre-Flight Physical Training, In-Flight Exercise Countermeasures and the Post-Flight Reconditioning Program for International Space Station Astronauts

2011-01-01

International Space Station (ISS) astronauts receive supervised physical training pre-flight, utilize exercise countermeasures in-flight, and participate in a structured reconditioning program post-flight. Despite recent advances in exercise hardware and prescribed exercise countermeasures, ISS crewmembers are still found to have variable levels of deconditioning post-flight. This presentation provides an overview of the astronaut medical certification requirements, pre-flight physical training, in-flight exercise countermeasures, and the post-flight reconditioning program. Astronauts must meet medical certification requirements on selection, annually, and prior to ISS missions. In addition, extensive physical fitness testing and standardized medical assessments are performed on long duration crewmembers pre-flight. Limited physical fitness assessments and medical examinations are performed in-flight to develop exercise countermeasure prescriptions, ensure that the crewmembers are physically capable of performing mission tasks, and monitor astronaut health. Upon mission completion, long duration astronauts must re-adapt to the 1 G environment, and be certified as fit to return to space flight training and active duty. A structured, supervised postflight reconditioning program has been developed to prevent injuries, facilitate re-adaptation to the 1 G environment, and subsequently return astronauts to training and space flight. The NASA reconditioning program is implemented by the Astronaut Strength, Conditioning, and Rehabilitation (ASCR) team and supervised by NASA flight surgeons. This program has evolved over the past 10 years of the International Space Station (ISS) program and has been successful in ensuring that long duration astronauts safely re-adapt to the 1 g environment and return to active duty. Lessons learned from this approach to managing deconditioning can be applied to terrestrial medicine and future exploration space flight missions.

Whole genome sequencing (WGS) is being used for evaluation of individuals with undiagnosed disease of suspected genetic origin. Implementing WGS into clinical practice will place an increased burden upon care teams with regard to pre-test patient education and counseling about results. To quantitate the time needed for appropriate pre-test evaluation of participants in WGS testing, we documented the time spent by our clinical research group on various activities related to program preparation, participant screening, and consent prior to WGS. Participants were children or young adults with autism, intellectual or developmental disability, and/or congenital anomalies, who have remained undiagnosed despite previous evaluation, and their biologic parents. Results showed that significant time was spent in securing allocation of clinical research space to counsel participants and families, and in acquisition and review of participant's medical records. Pre-enrollment chart review identified two individuals with existing diagnoses resulting in savings of $30,000 for the genome sequencing alone, as well as saving hours of personnel time for genome interpretation and communication of WGS results. New WGS programs should plan for costs associated with additional pre-test administrative planning and patient evaluation time that will be required to provide high quality care.
