HESI exams: consequences and remediation.  

PubMed

A growing body of knowledge supports the use of Elsevier's standardized HESI exams as an admission criterion to evaluate ongoing student performance and curricular outcomes and to measure students' preparedness for the National Council Licensure Examination for Registered Nurses (NCLEX-RN). Because a plethora of research indicates that the HESI Exit Exam (E(2)) is a valid predictor of NCLEX-RN success, faculty often designate a benchmark E(2) score that students are required to achieve. Students who do not achieve the faculty-designated benchmark score are required to remediate and retest with a parallel version of the E(2) to determine the effectiveness of the remediation and to reevaluate the student's preparedness for the licensure exam. This study compared mean E(2) scores of students who attended schools that attached consequences to E(2) scores with students who attended schools that did not attach consequences to E(2) scores. Based on data obtained from the Eighth Validity Study Questionnaire, findings indicated that E(2) scores were significantly higher (P < .01) in schools that associated consequences with failure to achieve the faculty-designated E(2) score and were also significantly higher (P < .01) in schools that required, rather than merely suggested remediation.

Physics Exams that Promote Collaborative Learning  

NASA Astrophysics Data System (ADS)

The two-stage exam is a relatively simple way to introduce collaborative learning and formative assessment into an exam. Their use is rapidly growing in the physics department at the University of British Columbia, as both students and faculty find them rewarding. In a two-stage exam students first complete and turn in the exam individually, and then, working in small groups, answer the exam questions again. During the second stage, the room is filled with spirited and effective debate with nearly every student participating. This provides students with immediate targeted feedback supplied by discussions with their peers. Furthermore, we see indications that the use of this exam format not only ensures consistency across interactive course components, but it also positively impacts how students approach the other collaborative course components. This is accomplished without losing the summative assessment of individual performance that is the expectation of exams for most instructors. In this paper we describe how to implement two-stage exams and provide arguments why they should be part of physics courses that use interactive engagement and social/collaborative learning methods.

A New Comprehensive Final Exam  

NASA Astrophysics Data System (ADS)

Instructors aspire for students to master all the material covered. The final exam should assess the breadth and depth of their learning and be a significant basis for the final grade. I insist on a comprehensive final because I want students to review early material in light of later topics. I believe that this helps students create connections, integrate understanding, and retain knowledge for the long term. For non-science majors, reviewing and retaining the large amount of astronomy material is daunting. I experimented with a final exam format that calmed their fears and encouraged thorough review. It is only practical for a class of about twenty students or less. I provided a number of challenging conceptual and problem solving questions (at least as many as there were students), crafted to interconnect and span the entire range of topics. The order of the questions reflected the sequence in which the topics had been discussed. Students received these questions in ample time to prepare prior to the final. A student could bring up to 5 standard sheets of notes to the final. At the final, each student picked a number out of a hat. This was the question they had to answer in a 5-minute presentation. They were allowed 15 minutes for a final preparation during which they could use their 5 pages of notes. The presentations were given in order, 1- 20. Written comments on at least 10 other talks, explaining what was missed or correcting a mistake were required. They were graded both on their talk and on their comments. This format required students to be prepared for any question and encouraged interaction and communication while studying. Knowing the questions beforehand provided a guide to their studying as well as allayed their fears about what could be asked. The students also received guidance to what constituted a good answer, namely accuracy (correct scientific argument, appropriate facts, no irrelevant material), thoroughness (answered the complete questions, covered relevant material) and the quality of the presentation (polished, professional, use of demonstrations, graphs, pictures etc. and time appropriately to present a clear answer). I will describe this first attempt.

The Exam-Room Physician Workstation

By combining and configuring commercially available hardware and software, we have developed a networked system of exam-room physician workstations that provides a platform for physician charting, medical reference, and patient education. The physical platform consists of IBM compatible computers and ethernet hardware. The software platform is a hypertext document management system called Idex distributed on a Novell network. Key features of the workstation include a graphical user interface, hypertext information access, network file-locking, and a document management shell. Clinical experience with the workstation suggests that patients accept the presence of a computer in the exam-room and that a hypertext medical record provides the speed of information access necessary for exam-room computing.

Improving the security of quantum exam against cheating  

E-print Network

The security of quantum exam [Phys. Lett. A 350 (2006) 174] is analyzed and it is found that this protocol is secure for any eavesdropper except for the "students" who take part in the exam. Specifically, any student can steal other examinees' solutions and then cheat in the exam. Furthermore, a possible improvement of this protocol is presented.

Physics exam preparation: A comparison of three methods  

NASA Astrophysics Data System (ADS)

In this clinical study on helping students prepare for an exam, we compared three different treatments. All students were asked to take a practice exam. One group was then given worked-out solutions for that exam, another group was given the solutions and targeted exercises to do as homework based on the result of their practice exam, and the third group was given the solutions, homework, and also an hour of one-on-one tutoring. Participants from all three conditions significantly outperformed the control group on the midterm exam. However, participants that had one-on-one tutoring did not outperform the other two participant groups.

[A master's exam in surgical training].  

PubMed

AN EXAMPLE FOR THE PRESENT DAY: The current requirement for explicit quality standards and examination of surgeons is an opportunity to contemplate surgical training from a historical perspective by looking at the regulations of the Amsterdam Surgeons' Guild (1461-1736). At that time Amsterdam surgeons usually trained for five years in a master-apprentice relationship under the guidance of a master surgeon in a surgeon's shop. An important part of the surgical training took place in the botanical gardens and anatomical theatre, where, during the weekly lessons, the praelector anatomiae would also demonstrate anatomy on the bodies of the deceased. Surgical training was complete after the trainee had passed the 'meesterproef' (master's exam), in which the manufacturing of lancets, blood-letting and performing a trepanation on a skull played a major part. However, over the course of time the final master's exam as the ultimate test of capability at the end of surgical training has disappeared. From the perspective of renewed interest in explicit quality standards and examination of surgeons, the reintroduction of a modern master's exam should perhaps be considered. PMID:20178655

Understanding Student Preparation of Exam Note Sheets  

NSDL National Science Digital Library

In a previous study, I allowed introductory physics students to create a notecard (or sheet) for their midterm and final exams in an attempt to remove equation memorizing as a focus of the course. I hoped to use the study of these cards as an epistemological lens that would uncover their perceptions and attitudes about the course. Without follow-up questions, though, epistemology remained unclear. I have continued this line of research by adding anonymous survey questions that probe why students chose to include what they did, how (if at all) the notes were helpful, and how their card preparation changed throughout the semester. Through my analysis, I found cases where the survey questions reveal epistemological insight about students the note sheets alone would not. For example, one student with an equation-centered note sheet did not see equations as the most central course component, but he considered himself fluent enough in concepts that he felt he could leave conceptual statements out. I also discuss some of the more thoughtful survey answers I received, some future study possibilities, and efforts to discuss exam preparation in the classroom.

Do Open-Book Exams Impede Long-Term Learning in Introductory Biology Courses?  

NSDL National Science Digital Library

Students in an introductory biology course who were given open-book exams during the semester earned significantly higher grades on these exams, but significantly lower grades on the closed-book final exam, than students who took in-class, closed-book exams throughout the semester. Exam format was also associated with changes in academic behavior; students who had upcoming open-book exams attended fewer lectures and help sessions and submitted fewer extra-credit assignments than students who had upcoming closed-book exams. These results suggest that open-book exams diminish long-term learning and promote academic behaviors that typify lower levels of academic achievement.

Evaluating multiple-choice exams in large introductory physics courses  

NSDL National Science Digital Library

The reliability and validity of professionally written multiple-choice exams have been extensively studied for exams such as the SAT, graduate record examination, and the force concept inventory. Much of the success of these multiple-choice exams is attributed to the careful construction of each question, as well as each response. In this study, the reliability and validity of scores from multiple-choice exams written for and administered in the large introductory physics courses at the University of Illinois, Urbana-Champaign were investigated. The reliability of exam scores over the course of a semester results in approximately a 3% uncertainty in students total semester exam score. This semester test score uncertainty yields an uncertainty in the students assigned letter grade that is less than 1/3 of a letter grade. To study the validity of exam scores, a subset of students were ranked independently based on their multiple-choice score, graded explanations, and student interviews. The ranking of these students based on their multiple-choice score was found to be consistent with the ranking assigned by physics instructors based on the students written explanations ( r>0.94 at the 95% confidence level) and oral interviews (r=0.94?..).

Will students pass a competitive exam that they failed in their dreams?  

PubMed

We tested whether dreams can anticipate a stressful exam and how failure/success in dreams affect next-day performance. We collected information on students' dreams during the night preceding the medical school entrance exam. Demographic, academic, sleep and dream characteristics were compared to the students' grades on the exam. Of the 719 respondents to the questionnaire (of 2324 total students), 60.4% dreamt of the exam during the night preceding it. Problems with the exam appeared in 78% of dreams and primarily involved being late and forgetting answers. Reporting a dream about the exam on the pre-exam night was associated with better performance on the exam (p=.01). The frequency of dreams concerning the exam during the first term predicted proportionally higher performance on the exam (R=0.1, p=.01). These results suggest that the negative anticipation of a stressful event in dreams is common and that this episodic simulation provides a cognitive gain. PMID:25108280

The rape exam: beyond the hospital emergency room.

The sites include regular hospital ERs (N = 25), specialized sexual assault treatment centers (SATCs) on hospital grounds (N = 2), a nonhospital-based SATC, a proprietary OB/GYN clinic, a medical examiner's office, and a law enforcement crime lab. Open-ended interviews indicate that major problems with hospitals as exam sites stem from physicians' dislike of the exam and physician and hospital fears of legal and court entanglements. Prosecutors (and judges) are a major obstacle to nonphysician examiners. A challenge to rethink the post-rape exam, including where and by whom it is performed, is posed. PMID:3321722

Are study strategies related to medical licensing exam performance?  

PubMed Central

Objectives: To examine the relationship between study strategies and performance on a high stakes medical licensing exam entitled the United States Medical Licensing Examination Step 1. Methods: The action research project included seventy nine student participants at the Texas A&M Health Science Center College of Medicine during their pre-clinical education. Data collection included pre-matriculation and matriculation academic performance data, standardized exam data, and the Learning and Study Strategies Instrument. Multiple regression analyses were conducted. For both models, the dependent variable was the Step 1 score, and the independent variables included Medical College Admission Test, Undergraduate Grade Point Average, Year 1 Average, Year 2 Average, Customized National Board of Medical Examiners Average, Comprehensive Basic Science Exam score, and Learning and Study Strategy Instrument sub-scores. Model 2 added Comprehensive Basic Science Self-Assessment average. Results: Concentration (Model 1 - ? = .264; Model 2 - ? = .254) was the only study strategy correlated with Step 1 performance. The other statistically significant predictors were Customized National Board of Medical Examiners Average (? = .315) and Year 2 Average (? = .280) in Model 1 and Comprehensive Basic Science Self-Assessment Average (? = .338) in Model 2. Conclusions: There does appear to be a relationship between the study strategy concentration and Step 1 licensing exam performance. Teaching students to practice and utilize certain techniques to improve concentration skills when preparing for and taking exams may help improve licensing exam scores. PMID:25362627

Effect of paper color on students' physics exam performances  

NSDL National Science Digital Library

Prior work has established the existence of a color-performance relationship in achievement contexts and has demonstrated its presence in some undergraduate course examinations. This study examines the manifestation of such a relationship in an introductory, 430-student, calculus-based electricity and magnetism course during which the paper color used in examinations was varied. In this report, we analyze three separate exams and differentiate between students multiple choice, written response, conceptual, and computational performances. Also considered are factors such as the time students require to complete exams and their confidence levels prior to and immediately following assessment. Performance in all categories appears to be independent of paper color.

Investigating the Effects of Exam Length on Performance and Cognitive Fatigue  

PubMed Central

This study examined the effects of exam length on student performance and cognitive fatigue in an undergraduate biology classroom. Exams tested higher order thinking skills. To test our hypothesis, we administered standard- and extended-length high-level exams to two populations of non-majors biology students. We gathered exam performance data between conditions as well as performance on the first and second half of exams within conditions. We showed that lengthier exams led to better performance on assessment items shared between conditions, possibly lending support to the spreading activation theory. It also led to greater performance on the final exam, lending support to the testing effect in creative problem solving. Lengthier exams did not result in lower performance due to fatiguing conditions, although students perceived subjective fatigue. Implications of these findings are discussed with respect to assessment practices. PMID:23950918

Introduction The purpose of this study is to describe an approach for evaluating assessments used in the first 2 years of medical school and report the results of applying this method to current first and second year medical student examinations. Methods Three faculty members coded all exam questions administered during the first 2 years of medical school. The reviewers discussed and compared the coded exam questions. During the bi-monthly meetings, all differences in coding were resolved with consensus as the final criterion. We applied Moore's framework to assist the review process and to align it with National Board of Medical Examiners (NBME) standards. Results The first and second year medical school examinations had 0% of competence level questions. The majority, more than 50% of test questions, were at the NBME recall level. Conclusion It is essential that multiple-choice questions (MCQs) test the attitudes, skills, knowledge, and competency in medical school. Based on our findings, it is evident that our exams need to be improved to better prepare our medical students for successful completion of NBME step exams. PMID:23469935

Does the Number of Hours Studied Affect Exam Performance?  

NSDL National Science Digital Library

This article describes a study in which the number of hours that students studied (determined by askng them) was examined to see how it affected exam performance. The study covered two courses at different institutions over a total of six semesters. Using the overall exam averages and regression analysis, the researchers calculated that students needed to invest from 3.0 to 4.4 hours to earn an average score and from 4.5 to 6.4 hours to earn an A (90 percent or 45 points out of 50) on average. In addition, they determined that the ratio of hours studied to lecture hours needed to earn a score of 90 percent ranged from 1.5 to 2.1 hours with a mean of 1.7, less than the "Carnegie Rule" of 2 hours of outside study time per week for each course credit (where a course credit is equivalent to 1 hour of lecture).

Uncovering an Existential Barrier to Breast Self-exam Behavior  

PubMed Central

The present research applies an analysis derived from terror management theory to the health domain of breast examination, and in doing so uncovers previously unrecognized factors that may contribute to womens reluctance to perform breast self-examinations (BSEs). In Study 1, when concerns about mortality were primed, reminders of human beings physical nature (i.e., creatureliness) reduced intentions to conduct BSEs compared to reminders of humans uniqueness. In Study 2, women conducted shorter exams on a breast model (an experience found to increase death-thought accessibility) when creatureliness was primed compared to a uniqueness and no essay condition. In Study 3, after a creatureliness prime, women performed shorter BSEs when a placebo did not provide an alternative explanation for their discomfort compared to when it did. Advances for theory and breast self-exam promotion are discussed. PMID:19255593

Emergency medicine residents attitudes and opinions of in-training exam preparation  

PubMed Central

Purpose Emergency Medicine (EM) residents take the American Board of Emergency Medicine (ABEM) in-training exam, and performance on this exam has been shown to correlate to performance on the ABEM qualifying exam. Though many residencies have in-training exam preparation activities, there is little data on the effectiveness of these efforts. This study aimed to elicit resident perspectives about the exam and exam preparation in order to generate hypotheses and better inform future preparation efforts. Methods Second- and third-year EM residents at a single institution were interviewed using a semi-structured format. Qualitative methodology was used to analyze the data. Results Thirteen EM residents participated in the study. Eight major themes and 18 sub-themes were identified. These were further characterized as relating to the exam itself or to exam preparation. Residents generally value the in-training exam. Sixty-nine percent noted that it provided an assessment of their current knowledge and deficiencies. Thirty-eight percent noted that it improved familiarity with the qualifying exam. Regarding exam preparation, residents stated that a question format was preferred, especially when accompanying explanations were of high quality. Additionally, practical considerations, such as portability, impacted resident selection of study tools. Conclusion Residents value the in-training exam as a marker of their academic progress and for their ability to gain familiarity with the qualifying exam. They prefer question-based preparation over text-based learning, as long as there is a detailed explanation of each answer. Educators creating structured in-training review may want to focus on question-based material with detailed explanations. PMID:24062620

How accurately can students estimate their performance on an exam and how does this relate to their actual performance on the exam?  

NSDL National Science Digital Library

Research has shown students' beliefs regarding their own abilities in math and science can influence their performance in these disciplines. I investigated the relationship between students' estimated performance and actual performance on five exams in a second semester calculus-based physics class. Students in a second-semester calculus-based physics class were given about 72 hours after the completion of each of five exams, to estimate their individual and class mean score on each exam. Students were given extra credit worth 1% of the exam points for estimating their score correct within 2% of the actual score and another 1% extra credit for estimating the class mean score within 2% of the correct value. I compared students' individual and mean score estimations with the actual scores to investigate the relationship between estimation accuracies and exam performance of the students as well as trends over the semester.

Want to Reduce Guessing and Cheating While Making Students Happier? Give More Exams!  

NASA Astrophysics Data System (ADS)

It is almost universally agreed that more frequent formative assessment (homework, clicker questions, practice tests, etc.) leads to better student performance and generally better course evaluations. There is, however, only anecdotal evidence that the same would be true for more frequent summative assessment (exams). There maybe many arguments against giving more exams, including the general "pain" associated with examinations, as well as reduced teaching time, since classroom sessions are dedicated to exams rather than lecturing. We present evidence that increasing the number of exams in fact does lead to better learning success, less cheating and guessing on homework, and better student course evaluations.

Question-writing as a learning tool for students outcomes from curricular exams  

PubMed Central

Background Writing exam questions can be a valuable learning tool. We asked students to construct multiple choice questions for curricular exams in Internal Medicine. The questions for the particular exams were chosen from a pool of at least 300 student-written questions. The uncorrected pool was accessible to all students. We studied the influence of this approach on the students learning habits and their test results. We hypothesized that creating a pool of their own questions for the exams could encourage students to discuss the learning material. Methods All students had to pass 4 exams in 7 fields of Internal Medicine. Three exams were comprised of 20 questions, and we applied the new method in one of these exams. The fourth exam was comprised of 30 questions, 15 of which were chosen from a students pool. After all exams had been completed we asked the students to fill in a web-based questionnaire on their learning habits and their views on the new approach. The test-results were compared to the results of the lecturers questions that defined high and low performing students. Results A total of 102 students completed all four exams in a row, 68 of whom filled in the questionnaire. Low performing students achieved significantly better results in the students questions. There was no difference in the number of constructed questions between both groups of students. The new method did not promote group work significantly. However, high performing students stated a stronger wish to be rewarded by good performance. Conclusions Creating a curricular exam by choosing questions from a pool constructed by students did not influence the learning habits significantly and favored low performing students. Since the high performing students sought to be rewarded for their efforts, we do not consider the approach applied in our study to be appropriate. PMID:23787038

Correlation of the NBME Advanced Clinical Examination in EM and the National EM M4 exams  

PubMed Central

Introduction Since 2011 two online, validated exams for fourth-year emergency medicine (EM) students have been available (National EM M4 Exams). In 2013 the National Board of Medical Examiners offered the Advanced Clinical Examination in Emergency Medicine (EM-ACE). All of these exams are now in widespread use; however, there are no data on how they correlate. This study evaluated the correlation between the EM-ACE exam and the National EM M4 Exams. Methods From May 2013 to April 2014 the EM-ACE and one version of the EM M4 exam were administered sequentially to fourth-year EM students at five U.S. medical schools. Data collected included institution, gross and scaled scores and version of the EM M4 exam. We performed Pearsons correlation and random effects linear regression. Results 303 students took the EM-ACE and versions 1 (V1) or 2 (V2) of the EM M4 exams (279 and 24, respectively). The mean percent correct for the exams were as follows: EM-ACE 74.8 (SD-8.83), V1 83.0 (SD-6.41), V2 78.5 (SD-7.70). Pearsons correlation coefficient for the V1/EM-ACE was 0.51 (0.42 scaled) and for the V2/EM-ACE was 0.59 (0.41 scaled). The coefficient of determination for V1/EM-ACE was 0.72 and for V2/EM-ACE = 0.71 (0.86 and 0.49 for scaled scores). The R-squared values were 0.25 and 0.30 (0.18 and 0.13, scaled), respectively. There was significant cluster effect by institution. Conclusion There was moderate positive correlation of student scores on the EM-ACE exam and the National EM M4 Exams.

A Java speech implementation of the Mini Mental Status Exam.  

PubMed

The Folstein Mini Mental Status Exam (MMSE) is a simple, widely used, verbally administered test to assess cognitive function. The Java Speech Application Programming Interface (JSAPI) is a new, cross-platform interface for both speech recognition and speech synthesis in the Java environment. To evaluate the suitability of the JSAPI for interactive, patient interview applications, a JSAPI implementation of the MMSE was developed. The MMSE contains questions that vary in structure in order to assess different cognitive functions. This question variability provided an excellent test-bed to evaluate the strengths and weaknesses of JSAPI. The application is based on Java platform 2 and a JSAPI interface to the IBM ViaVoice recognition engine. Design and implementations issues are discussed. Preliminary usability studies demonstrate that an automated MMSE maybe a useful screening tool for cognitive disorders and changes. PMID:10566396

Seamless insertion of real pulmonary nodules in chest CT exams  

NASA Astrophysics Data System (ADS)

The availability of large medical image datasets is critical in many applications such as training and testing of computer aided diagnosis (CAD) systems, evaluation of segmentation algorithms, and conducting perceptual studies. However, collection of large repositories of clinical images is hindered by the high cost and difficulties associated with both the accumulation of data and establishment of the ground truth. To address this problem, we are developing an image blending tool that allows users to modify or supplement existing datasets by seamlessly inserting a real lesion extracted from a source image into a different location on a target image. In this study we focus on the application of this tool to pulmonary nodules in chest CT exams. We minimize the impact of user skill on the perceived quality of the blended image by limiting user involvement to two simple steps: the user first draws a casual boundary around the nodule of interest in the source, and then selects the center of desired insertion area in the target. We demonstrate examples of the performance of the proposed system on samples taken from the Lung Image Database Consortium (LIDC) dataset, and compare the noise power spectrum (NPS) of blended nodules versus that of native nodules in simulated phantoms.

Sleep quality during exam stress: the role of alcohol, caffeine and nicotine.  

PubMed

Academic exam stress is known to compromise sleep quality and alter drug consumption in university students. Here we evaluated if sleeping problems and changes in legal drug consumption during exam stress are interrelated. We used the Pittsburgh Sleep Quality Index (PSQI) to survey sleep quality before, during, and after an academic exam period in 150 university students in a longitudinal questionnaire study. Self-reports of alcohol, caffeine, and nicotine consumption were obtained. The Perceived Stress Questionnaire (PSQ-20) was used as a measure of stress. Sleep quality and alcohol consumption significantly decreased, while perceived stress and caffeine consumption significantly increased during the exam period. No significant change in nicotine consumption was observed. In particular, students shortened their time in bed and showed symptoms of insomnia. Mixed model analysis indicated that sex, age, health status, as well as the amounts of alcohol and caffeine consumed had no significant influence on global sleep quality. The amount of nicotine consumed and perceived stress were identified as significant predictors of diminished sleep quality. Nicotine consumption had a small-to-very-small effect on sleep quality; perceived stress had a small-to-moderate effect. In conclusion, diminished sleep quality during exam periods was mainly predicted by perceived stress, while legal drug consumption played a minor role. Exam periods may pose an interesting model for the study of stress-induced sleeping problems and their mechanisms. PMID:25279939

Test Anxiety Levels of Board Exam Going Students in Tamil Nadu, India  

PubMed Central

The latest report by the National Crime Records Bureau has positioned Tamil Nadu as the Indian state with highest suicide rate. At least in part, this is happening due to exam pressure among adolescents, emphasizing the imperative need to understand the pattern of anxiety and various factors contributing to it among students. The present study was conducted to analyze the level of state anxiety among board exam attending school students in Tamil Nadu, India. A group of 100 students containing 50 boys and 50 girls from 10th and 12th grades participated in the study and their state anxiety before board exams was measured by Westside Test Anxiety Scale. We found that all board exam going students had increased level of anxiety, which was particularly higher among boys and 12th standard board exam going students. Analysis of various demographic variables showed that students from nuclear families presented higher anxiety levels compared to their desired competitive group. Overall, our results showing the prevalence of state anxiety among board exam going students in Tamil Nadu, India, support the recent attempt taken by Tamil Nadu government to improve student's academic performance in a healthier manner by appointing psychologists in all government schools.

A comparison of student performance on discipline-specific versus integrated exams in a medical school course.  

PubMed

Curricular reform is a widespread trend among medical schools. Assessing the impact that pedagogical changes have on students is a vital step in review process. This study examined how a shift from discipline-focused instruction and assessment to integrated instruction and assessment affected student performance in a second-year medical school pathology course. We investigated this by comparing pathology exam scores between students exposed to traditional discipline-specific instruction and exams (DSE) versus integrated instruction and exams (IE). Exam content was controlled, and individual questions were evaluated using a modified version of Bloom's taxonomy. Additionally, we compared United States Medical Licensing Examination (USMLE) step 1 scores between DSE and IE groups. Our findings indicate that DSE students performed better than IE students on complete pathology exams. However, when exam content was controlled, exam scores were equivalent between groups. We also discovered that the integrated exams were composed of a significantly greater proportion of questions classified on the higher levels of Bloom's taxonomy and that IE students performed better on these questions overall. USMLE step 1 exam scores were similar between groups. The finding of a significant difference in content complexity between discipline-specific and integrated exams adds to recent literature indicating that there are a number of potential biases related to curricular comparison studies that must be considered. Future investigation involving larger sample sizes and multiple disciplines should be performed to explore this matter further. PMID:24292915

Realisation of the guidelines for faculty-internal exams at the Department of General Medicine at the University of Munich: Pushing medical exams one step ahead with IMSm.  

PubMed

Graded exams are prerequisites for the admission to the medical state examination. Accordingly the exams must be of good quality in order to allow benchmarking with the faculty and between different universities. Criteria for good quality need to be considered - namely objectivity, validity and reliability. The guidelines for the processing of exams published by the GMA are supposed to help maintaining those criteria. In 2008 the Department of General Medicine at the University of Munich fulfils only 14 of 18 items. A review process, appropriate training of the staff and the introduction of the IMSm software were the main changes that helped to improve the 'GMA-score' to 30 fulfilled items. We see the introduction of the IMSm system as our biggest challenge ahead. IMSm helps to streamline the necessary workflow and improves their quality (e.g. by the detection of cueing, item analysis). Overall, we evaluate the steps to improve the exam process as very positive. We plan to engage co-workers outside the department to assist in the various review processes in the future. Furthermore we think it might be of value to get into contact with other departments and faculties to benefit from each other's question pools. PMID:22737197

Matching images from digital modalities to exams scheduled via RIS or PACS  

NASA Astrophysics Data System (ADS)

In many hospitals, radiological examinations are scheduled via a Radiology Information System (RIS) or Picture Archiving and Communication System (PACS) before the imaging is performed. Demographic and examination information is first entered into the PACS database; when the images are later acquired, they have to match up with the correct pre-scheduled exam. This problem is non-trivial because patients may be scheduled for several exams on the same modality on the same day, and older modalities are unable to identify unambiguously the type of examination being performed. The purpose of this work is to develop practical and reliable strategies to assist in matching up the correct exam. Three potential solutions are considered: (1) modifications to imaging hardware and/or software, which force a PACS- generated exam ID into the image headers at acquisition time and thus guarantee a perfect match; (2) profiling algorithms, which attempt to find a match based on information already contained within the image headers; and (3) interactive Modality Examination Terminals (METs), which query the PACS database and assist human operators in manually selecting an appropriate exam. Solution (1) was found to be impractical with our existing digital imaging equipment, therefore solutions (2) and (3) were implemented and evaluated. Configuration files read at start-up time permitted the same hardware to be operated in either profiling or true MET mode. For each digital imaging modality the most appropriate mode of operation was determined, maintaining as far as possible a consistent hardware and software user interface.

Do You Prefer to Have the Text or a Sheet with Your Physics Exams?  

NASA Astrophysics Data System (ADS)

Many high school and introductory college physics instructors ponder the choice between "open text" exams versus "facts and formulae sheet" exams. Other alternatives are closed book/closed notes exams or an instructor-prepared sheet of facts and relevant formulas. There is no agreement on merit. Rehfuss strongly opposes allowing students to use formula sheets while taking physics exams despite acknowledging that such use is common practice. Cone2 responded to Rehfuss by defending the use of such sheets and outlining the benefits of a "cheat sheet." Debate over the use of a "cheat sheet" or other resources during exams is not limited to the physics community. Skidmore and Aagaard3 studied the relationship between testing conditions and student test scores for students in teacher education. Two decades earlier Boniface,4 Dorsal and Cundiff,5 and Hindman6 published papers on the use of texts and/or sheets during examinations in psychology and education. Others, such as Pullen et al.7 focused on studying the discarded cheat sheets themselves. Humorously, in October 2005 The New York Times8 reported an unusual museum exhibit of "cheat sheets" and the different ways students had cheated at a particular university.

Teacher-Generated Final Exams in High School Science: Content, Rigor, and Assessment Literacy  

NASA Astrophysics Data System (ADS)

This study investigates a large collection of teacher-generated end-of-semester final exams from Chicago Public School high school science classrooms in order to explore the depth and breadth of content that students learn in science classrooms. Teachers focus on a specific set of scientific content that is driven by district guidelines and popular textbooks but not particularly aligned to standards. To most teachers, rigor means coverage instead of intellectual press. The assessments, while unsophisticated, seem to be delivering what is expected of them---a way to mimic the most basic format of the ACT exam quickly. There was little variation among high poverty and low poverty schools, matching national data and indicating issues that are more due to a particular culture of science teaching and learning than driven by particular contexts. The study identifies implications for the observed homogeneity of final exam rigor and content, identifies gaps between how the routine of final exams are design and implemented in schools, and discusses similar methodological efforts that could enhance the ability of schools and districts to access useful information about the technical core of instruction.

Creation of a diagnostic exam for introductory, undergraduate electricity and magnetism  

NASA Astrophysics Data System (ADS)

To fill the need for a tool testing introductory, undergraduates' knowledge of basic concepts in electricity and magnetism (EM), the investigator has developed a sixty-six item, multiple-choice diagnostic exam (DEEM). This thesis chronicles the iterative development of the DEEM. The exam is intended to provide physics instructors with a psychometrically sound instrument that serves three general purposes: (1) gauge students' pre-instructional knowledge (baseline assessment), assess students' post- instructional achievement, and provide scores to determine students' conceptual learning gains; (2) yield results that are maximally diagnostic to instructors by highlighting students' most common misconceptions and reveling patterns of responses which are easily interpreted by physics instructors; and (3) provide the physics education research community with a tool to measure the relative effectiveness of various curricula. The exam covers the following basic concepts of EM: forces on charged particles in electric or magnetic fields; properties of electric fields and magnetic fields; properties of electrostatic potential and potential energy; Maxwell's Equations; and induction, with Lenz's Law. Items comprising the DEEM do not require calculus, explicit calculations, or memorization of fundamental constants; are pictorially based; and generally explore high-symmetry scenarios. The most recent field-tested version of the DEEM (Version 3.0) yielded a coefficient alpha of 0.74 (post-test), a significant gain in score from pre-test to post-test, and no significant gender bias. The investigator established the exam's validity by surveying experienced instructors and widely used introductory physics textbooks during development of the DEEM. In addition, over 150 physics educators from around the world reviewed versions of this exam and offered comments and criticism on its content, emphasis, and layout.

Xenon spallation systematics in Angra DOS Reis  

NASA Astrophysics Data System (ADS)

Literature Xe data for the Angra dos Reis meteorite have been resolved into constituent spallation, fission and trapped components. The spallation Xe compositions vary over a range wider than observed in any other samples, including lunar samples. These variations are due to the mixing of spallation Xe from Ba and rare earth element targets. It is possible to infer the Ba and rare earth spallation Xe compositions. Angra dos Reis spallation Xe compositions are systematically different from those observed in lunar samples, possibly because of differences in the irradiation conditions (geometry and shielding). Thus the Angra dos Reis data appear to be superior to lunar data for predicting spallation Xe compositions in other meteorites.

Purpose To explore the use of over the counter (OTC) medicines among students during exams in Riyadh City, Kingdom of Saudi Arabia. Method A cross-sectional study was designed; using a self-administered twenty-two item online questionnaire for the students convenience and easy response disclosure. Data were analyzed using Statistical Package for Social Science (SPSS) version 13. Results A total of N=1596 students participated in this survey, of whom 829 (51.9%) were university students and 767 (48.1%) were high school students. Overall, 80.0% of the respondents disclosed the use of OTC non-steroidal anti-inflammatory drugs for headache and pain relief. In addition, other substances used during the exams were Energy Drinks (5.0%), Flu Medication (5.0%), Vitamins (5.0%) and Antibiotics (5.0%). Female students were found to be more knowledgeable about safety issues concerning the use of OTC medicines (5.111.27, p=<0.001) than male students. Ease in access to OTC medicine, availability of pharmacist consultation and advertisement in print and electronic media were the main factors disclosed by the respondents that may result in an increase in the use of OTC products. The use of OTC medicines was generally higher among female students (p=0.001). Conclusion The use of OTC medication during exams was more among high school and university students. Gender, age and educational institution were found significantly affecting the use of OTC medicines during exams. PMID:24648821

Foreign Exam Management in Practice: Seamless Access to Foreign Images and Results in a Regional Environment.  

PubMed

A challenge for many clinical users is that a patient may receive a diagnostic imaging (DI) service at a number of hospitals or private imaging clinics. The DI services that patients receive at other locations could be clinically relevant to current treatments, but typically, there is no seamless method for a clinical user to access longitudinal DI results for their patient. Radiologists, and other specialists that are intensive users of image data, require seamless ingestion of foreign exams into the picture archiving and communication system (PACS) to achieve full clinical value. Most commonly, a clinical user will depend on the patient to bring in a CD that contains imaging from another location. However, a number of issues can arise when using this type of solution. Firstly, a CD will not provide the clinical user with the full longitudinal record of the patient. Secondly, a CD often will not contain the report associated with the images. Finally, a CD is not seamless, due to the need to manually import the contents of the CD into the local PACS. In order to overcome these limitations, and provide clinical users with a greater benefit related to a patient's longitudinal DI history, the implementation of foreign exam management (FEM) at the local site level is required. This paper presents the experiences of FEM in practice. By leveraging industry standards and edge devices to support FEM, multiple sites with disparate PACS and radiology information system (RIS) vendors are able to seamlessly ingest foreign exams within their local PACS as if they are local exams.

Academic goals, goal process cognition, and exam performance among college students  

Microsoft Academic Search

We investigated the nature of and linkages between student-generated academic goals, individual differences in self-regulatory thinking (goal process cognition), and exam performance among college students. In Study 1 (N=365) and in Study 2 (N=325), we elicited students' self-ascribed most important academic goals for introductory psychology and their goal process cognition toward their most important goal. In addition, in Study 2,

Assessing high-level scientific reasoning in a physics exam: Pipe-dream or reality?  

NASA Astrophysics Data System (ADS)

What do we want students to be able to do when they have finished their introductory physics course? In addition to learning the physics content, we want students to learn to think like physicists. We want students to develop specific scientific reasoning abilities that are the hall-mark of scientific thinking. These include, analyzing and interpreting experimental data, designing an experiment to test different hypotheses, identifying assumptions in a physical model amongst many others. Physics courses such as the Investigative Science Learning Environment (ISLE) have been developed to focus specifically on developing students' scientific reasoning abilities. Research has shown that ISLE is successful in achieving its goal. We would like our assessments to directly reflect our learning goals for our students. In order to measure higher-level scientific reasoning, we can, for example, require students to participate in a laboratory practical exam in which they have to engage in experimental design and analysis. However, this assessment method could become very difficult to administer and grade in a large-enrollment class. Is it possible to assess scientific thinking abilities of students using traditional formats such as paper and pencil exams? In this talk I will present some of our latest ideas about how to re-design traditional exam questions to measure a range of scientific reasoning abilities.

Creation of a Diagnostic Exam for Introductory, Undergraduate Electricity and Magnetism  

NSDL National Science Digital Library

To fill the need for a tool testing introductory, undergraduates knowledge of basic concepts in electricity and magnetism (EM), the investigator has developed a sixty-six item, multiple-choice diagnostic exam (DEEM). The exam is intended to provide physics instructors with a psychometrically sound instrument that serves three general purposes: (1) gauge students' pre-instructional knowledge (baseline assessment), assess students' post-instructional achievement, and provide scores to determine students conceptual learning gains; (2) yield results that are maximally diagnostic to instructors by highlighting students' most common misconceptions and reveling patterns of responses which are easily interpreted by physics instructors; and (3) provide the physics education research community with a tool to measure the relative effectiveness of various curricula. The exam covers the following basic concepts of EM: forces on charged particles in electric or magnetic fields; properties of electric fields and magnetic fields; properties of electrostatic potential and potential energy; Maxwells Equations; and induction, with Lenzs Law. Items comprising the DEEM do not require calculus, explicit calculations, or memorization of fundamental constants; are pictorially based; and generally explore high-symmetry scenarios.

The UCSF screening exam effectively screens cognitive and behavioral impairment in patients with ALS.  

PubMed

The University of California San Francisco (UCSF) Screening Battery provides clinicians with a uniquely tailored tool to measure ALS patients' cognitive and behavioral changes, adjusting for dysarthria and hand weakness. The battery consists of the ALS-CBS ( 1 ), Written Fluency Test ( 2 ), and a new revision of the Frontal Behavior Inventory (FBI-ALS) ( 3 ). The validity of each component was tested by comparing results with a gold standard neuropsychological exam (GNE). Consensus criteria-based GNE diagnoses ( 4 ) were assigned (n = 24) and concurrent validity was tested for each screening exam component. Results showed that each of the four cognitive and behavioral screening test components were significantly associated with diagnoses confirmed by GNE. GNE diagnoses were significantly associated with FBI-ALS negative score, written S-words score, and ALS-CBS cognitive score. The total FBI-ALS score and C-words tests were less predictive of GNE-diagnosed impairment. In conclusion, the UCSF Cognitive Screening Battery demonstrates good external validity compared with GNE in this modest sample, encouraging its use in larger investigations. These data suggest that this battery may provide an effective screen to identify ALS patients who will then benefit from a full examination to confirm their diagnosis. PMID:25301548

The scare tactic: do fear appeals predict motivation and exam scores?  

PubMed

Prior to high-stakes exams, teachers use persuasive messages that highlight to students the possible consequences of failure. Such messages are known as fear appeals. This study examined whether fear appeals relate to self- and non-self-determined motivation and academic performance. Data were collected in 3 waves. Self-report data pertaining to perceived fear appeals were collected in the first wave, self-report data pertaining to self-determined motivation were collected in the second wave, and exam scores were collected in the third wave. An increased frequency of fear appeals and the appraisal of fear appeals as threatening predicted lower self-determined motivation but were largely unrelated to non-self-determined motivation. An increased frequency of fear appeals and the appraisal of fear appeals as threatening predicted lower examination performance that was partly mediated by lower self-determined motivation. These findings support a position derived from self-worth theory that the negative consequences of fear appeals arise from their focus on avoiding failure rather than their focus on extrinsic consequences. We suggest that teachers and instructors need to be aware how seemingly motivational statements can unwittingly promote lower self-determined motivation. PMID:24730693

Grading Multiple Choice Exams with Low-Cost and Portable Computer-Vision Techniques  

NASA Astrophysics Data System (ADS)

Although technology for automatic grading of multiple choice exams has existed for several decades, it is not yet as widely available or affordable as it should be. The main reasons preventing this adoption are the cost and the complexity of the setup procedures. In this paper, Eyegrade, a system for automatic grading of multiple choice exams is presented. While most current solutions are based on expensive scanners, Eyegrade offers a truly low-cost solution requiring only a regular off-the-shelf webcam. Additionally, Eyegrade performs both mark recognition as well as optical character recognition of handwritten student identification numbers, which avoids the use of bubbles in the answer sheet. When compared with similar webcam-based systems, the user interface in Eyegrade has been designed to provide a more efficient and error-free data collection procedure. The tool has been validated with a set of experiments that show the ease of use (both setup and operation), the reduction in grading time, and an increase in the reliability of the results when compared with conventional, more expensive systems.

Blooms' separation of the final exam of Engineering Mathematics II: Item reliability using Rasch measurement model  

NASA Astrophysics Data System (ADS)

In engineering studies and researches, Mathematics is one of the main elements which express physical, chemical and engineering laws. Therefore, it is essential for engineering students to have a strong knowledge in the fundamental of mathematics in order to apply the knowledge to real life issues. However, based on the previous results of Mathematics Pre-Test, it shows that the engineering students lack the fundamental knowledge in certain topics in mathematics. Due to this, apart from making improvements in the methods of teaching and learning, studies on the construction of questions (items) should also be emphasized. The purpose of this study is to assist lecturers in the process of item development and to monitor the separation of items based on Blooms' Taxonomy and to measure the reliability of the items itself usingRasch Measurement Model as a tool. By using Rasch Measurement Model, the final exam questions of Engineering Mathematics II (Linear Algebra) for semester 2 sessions 2012/2013 were analysed and the results will provide the details onthe extent to which the content of the item providesuseful information about students' ability. This study reveals that the items used in Engineering Mathematics II (Linear Algebra) final exam are well constructed but the separation of the items raises concern as it is argued that it needs further attention, as there is abig gap between items at several levels of Blooms' cognitive skill.

Emerging identity of Finnish nurse teachers: student teachers' narratives in a group exam.  

PubMed

In Finland students pursuing in Master's Degree Programme have a previous degree in nursing from polytechnics. Nurse teacher qualification also includes at least five year's experience of working in practice. This article concentrates on the conflicts student teachers brought up in a group exam as regards changing a nurse's identity into a teacher's identity in teacher training. The approach of the study on this group was narrative. The data were collected by videotaping two group exam situations (five hours in all) of volunteer student teachers (N= 5) during the last course (Nurse teacher's inquiring mind) of their nurse teacher studies in 2002. The material was transcribed and analysed using categorical-content reading to identify particular themes, story lines and messages within material. By abstracting these, stories that describe the content can be found. Three narratives emerged in the analysis: 1. Competence creates confidence; 2. Shared teacher identity; 3. Ethics of teacher identity. The narratives raised new ideas for developing nurse teacher education in the future. Nowadays, there are good prospects for developing a shared teacher identity if there is willingness to co-operate within a learning community of a new kind. PMID:16040167

How emotions affect logical reasoning: evidence from experiments with mood-manipulated participants, spider phobics, and people with exam anxiety.  

PubMed

Recent experimental studies show that emotions can have a significant effect on the way we think, decide, and solve problems. This paper presents a series of four experiments on how emotions affect logical reasoning. In two experiments different groups of participants first had to pass a manipulated intelligence test. Their emotional state was altered by giving them feedback, that they performed excellent, poor or on average. Then they completed a set of logical inference problems (with if p, then q statements) either in a Wason selection task paradigm or problems from the logical propositional calculus. Problem content also had either a positive, negative or neutral emotional value. Results showed a clear effect of emotions on reasoning performance. Participants in negative mood performed worse than participants in positive mood, but both groups were outperformed by the neutral mood reasoners. Problem content also had an effect on reasoning performance. In a second set of experiments, participants with exam or spider phobia solved logical problems with contents that were related to their anxiety disorder (spiders or exams). Spider phobic participants' performance was lowered by the spider-content, while exam anxious participants were not affected by the exam-related problem content. Overall, unlike some previous studies, no evidence was found that performance is improved when emotion and content are congruent. These results have consequences for cognitive reasoning research and also for cognitively oriented psychotherapy and the treatment of disorders like depression and anxiety. PMID:24959160

Accuracy and Feasibility of Dual Fluoroscopy and Model-Based Tracking to Quantify In Vivo Hip Kinematics During Clinical Exams  

PubMed Central

Accurate measurements of in-vivo hip kinematics may elucidate the mechanisms responsible for impaired function and chondrolabral damage in hips with femoroacetabular impingement (FAI). The objectives of this study were to quantify the accuracy and demonstrate the feasibility of using dual fluoroscopy to measure in-vivo hip kinematics during clinical exams used in the assessment of FAI. Steel beads were implanted into the pelvis and femur of two cadavers. Specimens were imaged under dual fluoroscopy during the impingement exam, FABER test, and rotational profile. Bead locations measured with model-based tracking were compared to those measured using dynamic radiostereometric analysis. Error was quantified by bias and precision, defined as the average and standard deviation of the differences between tracking methods, respectively. A normal male volunteer was also imaged during clinical exams. Bias and precision along a single axis did not exceed 0.17 and 0.21 mm, respectively. Comparing kinematics, positional error was less than 0.48 mm and rotational error was less than 0.58. For the volunteer, kinematics were reported as joint angles and bone-bone distance. These results demonstrate that dual fluoroscopy and model-based tracking can accurately measure hip kinematics in living subjects during clinical exams of the hip. PMID:24584728

The feasibility of patient size-corrected, scanner-independent organ dose estimates for abdominal CT exams  

PubMed Central

Purpose: A recent work has demonstrated the feasibility of estimating the dose to individual organs from multidetector CT exams using patient-specific, scanner-independent CTDIvol-to-organ-dose conversion coefficients. However, the previous study only investigated organ dose to a single patient model from a full-body helical CT scan. The purpose of this work was to extend the validity of this dose estimation technique to patients of any size undergoing a common clinical exam. This was done by determining the influence of patient size on organ dose conversion coefficients generated for typical abdominal CT exams. Methods: Monte Carlo simulations of abdominal exams were performed using models of 64-slice MDCT scanners from each of the four major manufacturers to obtain dose to radiosensitive organs for eight patient models of varying size, age, and gender. The scanner-specific organ doses were normalized by corresponding CTDIvol values and averaged across scanners to obtain scanner-independent CTDIvol-to-organ-dose conversion coefficients for each patient model. In order to obtain a metric for patient size, the outer perimeter of each patient was measured at the central slice of the abdominal scan region. Then, the relationship between CTDIvol-to-organ-dose conversion coefficients and patient perimeter was investigated for organs that were directly irradiated by the abdominal scan. These included organs that were either completely (fully irradiated) or partly (partially irradiated) contained within the abdominal exam region. Finally, dose to organs that were not at all contained within the scan region (nonirradiated) were compared to the doses delivered to fully irradiated organs. Results: CTDIvol-to-organ-dose conversion coefficients for fully irradiated abdominal organs had a strong exponential correlation with patient perimeter. Conversely, partially irradiated organs did not have a strong dependence on patient perimeter. In almost all cases, the doses delivered to nonirradiated organs were less than 5%, on average across patient models, of the mean dose of the fully irradiated organs. Conclusions: This work demonstrates the feasibility of calculating patient-specific, scanner-independent CTDIvol-to-organ-dose conversion coefficients for fully irradiated organs in patients undergoing typical abdominal CT exams. A method to calculate patient-specific, scanner-specific, and exam-specific organ dose estimates that requires only knowledge of the CTDIvol for the scan protocol and the patients perimeter is thus possible. This method will have to be extended in future studies to include organs that are partially irradiated. Finally, it was shown that, in most cases, the doses to nonirradiated organs were small compared to the dose to fully irradiated organs. PMID:21452719

The TRIPSE: a process-oriented exam for large undergraduate classes.

The TRIPSE (tri-partite problem solving exercise), a process-oriented exam that mimics the scientific process, was used previously in small classes (15-25). Provided limited data, students frame explanations and design experimental tests that they later revise with additional information. Our 6-year experience using it with larger numbers (155-204) in a freshman biology course, suggests that it could provide a means of assessing individual student performance. Students rated the learning value of this experience to be significantly higher than a standard MCQ on a 10-point scale (TRIPSEs 8.2, CI 8.1/8.4 vs. MCQs 4.9, CI 4.8/5.1, n = 712). Additionally, we tested one cohort (n = 146) with a group TRIPSE (groups of 6), and found that this variant also provided a valuable learning experience (8.0, CI 7.7/8.3). PMID:23649941

NASA Astrophysics Data System (ADS)

Understanding how geologists conduct fieldwork through analysis of problem solving has significant potential impact on field instruction methods. Recent progress has been made in this area but the problem solving behaviors displayed by geologists during fieldwork and the associated underlying cognition remains poorly understood. We present research showing how geology students initiate and develop geologic models as part of the problem solving process. We qualitatively analyzed field notes and interview data from 36 undergraduate geoscientists engaged in field exams while enrolled in a six-week advanced field camp. Eight cognitive frameworks grouped in two broad categories emerged from the data that show how students develop geologic models. Students employ both single and multiple model approaches with varying degrees of success and frequency. The success of any given approach is dependent on the level of students' geologic situational awareness. The development of multiple geologic models leads to a higher rate of success in general, because of the inherent flexibility to accommodate newly collected data. Instructors should continue to teach a multiple model approach until students have the proper geologic skills to ensure a high level of situational awareness and exhibit expert characteristics in the field. In addition, we collected GPS navigation data from students during these field exams in order to understand the relationship between navigation, cognition, and performance. From the analysis of this data we found that over half of all stops are 1-4 minutes long, while very few of students' stops are longer than 9 minutes as the frequency of stops decreases as the duration increases. Regardless of performance or framework, there is an increase in shorter stops and decrease in longer stops from exam one to three, indicating that students changed the way they investigated as the field course progressed. Temporal signatures categorized by performance only show slight differences, but do indicate that there is an increase in very short and longer stops with declining performance. In contrast, higher performance is linked to an increase in short and medium length stops, suggesting that stops 4-14 minutes long are a "sweet spot" for investigation. We speculate that a high percentage of very short stops involve basic field tasks such as locating or data collection and that the decreasing frequency of long stops indicates that there is a relationship between the length of the stop and the complexity of the activities performed during that stop. Students increased experience leads to more efficient stops as they become more competent with field tasks and more versed in the regional geology. The GPS data we collected from these students while they took these notes allowing us to connect the duration of a stop to the types of notes produced during that stop. Note taking species occurred in various frequencies with the most common type being those that focused on lithologic, or lithologic & structural data collection. Stops that produced geologic models, specifically structural models, were much less frequent. The more frequent data collection stops are very short in length (typically 1-4 minutes), while the more complex stops tend to be longer in duration as the note taking gets more complex. Poor performing students had a high proportion of stops where they only collect lithologic data or stops where they don't generate any hypotheses. In contrast, successful students have more structural data and hypothesis generation in their notes. From this analysis we conclude that too much effort spent on stops with only basic data collection leaves less time for the cognitive effort required for model development, eventually leading to poor exam performance. Specifically, a higher frequency of lithologic data stops and lack of structural data leads to the development of incomplete geologic models or lack of comprehensive models altogether. Field instructors often educate their students on good note taking practices and cr

Transition from partial to full PACS at a 450,000 exams/year hospital  

NASA Astrophysics Data System (ADS)

The purpose of this paper is to describe the transition of a 1,100 beds tertiary hospital from 50 percent softcopy operation to full PACS operation. For the past 2 years, radiologists and clinicians have been using PACS to provide softcopy services to the outpatient clinics and inpatient wards of orthopedics surgery, neurosurgery and neurology as well as emergency room, surgical intensive care unit, medical intensive unit, pediatrics intensive care unit and neonatal intensive care unit. The examinations requested by these departments account for about 50 percent of hospital's radiological exams. In September 1996, we began the second phase of PACS implementation and installed additional workstations in the remaining wards and clinics, interfaced to PACS additional imaging modalities, and increased the capacity of both the image server and optical juke boxes. As of January 1997, we are in the final phase of moving away from conventional film system to full PACS operation.

PCR-based method for detecting viral penetration of medical exam gloves.  

PubMed

The test approved by the U.S. Food and Drug Administration for assessment of the barrier quality of medical exam gloves includes visual inspection and a water leak test. Neither method tests directly the ability of gloves to prevent penetration by microorganisms. Methods that use microorganisms (viruses and bacteria) to test gloves have been developed but require classical culturing of the organism to detect it. We have developed a PCR assay for bacteriophage phiX174 that allows the rapid detection of penetration of gloves by this virus. The method is suitable for use with both latex and synthetic gloves. The presence of glove powder on either latex or synthetic gloves had no effect on the ability of the PCR assay to detect bacteriophage DNA. The assay is rapid, sensitive, and inexpensive; requires only small sample volumes; and can be automated. PMID:12149320

Going beyond standardized exam scores in graduate admissions: Enhancing diversity and predicting success  

NASA Astrophysics Data System (ADS)

We present the approach to graduate admissions developed by the Fisk-Vanderbilt Masters-to-PhD Bridge Program. The approach emphasizes a careful examination of applicants' basic academic preparedness together with noncognitive tracers of future success -- so-called "grit" or "performance character" -- and does not rely upon standardized exam scores such as GREs. This approach has enabled the Fisk-Vanderbilt program to identify and select large numbers of underrepresented minority students who are succeeding at the PhD level, making the program the nation's top producer of underrepresented minority PhDs in astronomy. We highlight outcomes of the program utilizing this "enlightened approach" to admissions, and share tools developed by the program for use by others.

The evaluation of physical exam findings in patients assessed for suspected burn inhalation injury.  

PubMed

The purpose of this investigation was to evaluate the utility of singed nasal hair (SN), carbonaceous sputum (CS), and facial burns (FB) as indicators of burn inhalation injury, when compared to the accepted standard of bronchoscopic diagnosis of inhalation injury. An institutional review board approved, retrospective review was conducted. All patients were suspected to have burn inhalation injury and subsequently underwent bronchoscopic evaluation. Data collected included: percent burn TBSA, burn injury mechanism, admission physical exam findings (SN, CS, FB), and bronchoscopy findings. Thirty-five males and twelve females met inclusion criteria (n = 47). Bronchoscopy was normal in 31 patients (66%). Data were analyzed as all patients and in subgroups according to burn TBSA and an enclosed space mechanism of injury. Physical exam findings (SN, CS, FB) were evaluated individually and in combination. Overall, the sensitivities, specificities, positive predictive values, and negative predictive values calculated were poor and inconsistent, and they did not improve within subgroup analysis or when physical findings were combined. Further statistical analysis suggested the physical findings, whether in isolation or in combination, have poor discrimination between patients that have and do not have inhalation injury (AUC < 0.7, P > .05) and poor agreement with the diagnosis made by bronchoscopy (? < 0.4, P > .05). This remained true in the subgroup analysis as well. Our data demonstrated the findings of SN, CS, and FB are unreliable evidence for inhalation injury, even in the context of an enclosed space mechanism of injury. Thus, these physical findings are not absolute indicators for intubation and should be interpreted as one component of the history and physical. PMID:25423438

Fast interrupt platform for extended DOS  

NASA Technical Reports Server (NTRS)

Extended DOS offers the unique combination of a simple operating system which allows direct access to the interrupt tables, 32 bit protected mode access to 4096 MByte address space, and the use of industry standard C compilers. The drawback is that fast interrupt handling requires both 32 bit and 16 bit versions of each real-time process interrupt handler to avoid mode switches on the interrupts. A set of tools has been developed which automates the process of transforming the output of a standard 32 bit C compiler to 16 bit interrupt code which directly handles the real mode interrupts. The entire process compiles one set of source code via a make file, which boosts productivity by making the management of the compile-link cycle very simple. The software components are in the form of classes written mostly in C. A foreground process written as a conventional application which can use the standard C libraries can communicate with the background real-time classes via a message passing mechanism. The platform thus enables the integration of high performance real-time processing into a conventional application framework.

The feasibility of a regional CTDIvol to estimate organ dose from tube current modulated CT exams  

PubMed Central

Purpose: In AAPM Task Group 204, the size-specific dose estimate (SSDE) was developed by providing size adjustment factors which are applied to the Computed Tomography (CT) standardized dose metric, CTDIvol. However, that work focused on fixed tube current scans and did not specifically address tube current modulation (TCM) scans, which are currently the majority of clinical scans performed. The purpose of this study was to extend the SSDE concept to account for TCM by investigating the feasibility of using anatomic and organ specific regions of scanner output to improve accuracy of dose estimates. Methods: Thirty-nine adult abdomen/pelvis and 32 chest scans from clinically indicated CT exams acquired on a multidetector CT using TCM were obtained with Institutional Review Board approval for generating voxelized models. Along with image data, raw projection data were obtained to extract TCM functions for use in Monte Carlo simulations. Patient size was calculated using the effective diameter described in TG 204. In addition, the scanner-reported CTDIvol (CTDIvol,global) was obtained for each patient, which is based on the average tube current across the entire scan. For the abdomen/pelvis scans, liver, spleen, and kidneys were manually segmented from the patient datasets; for the chest scans, lungs and for female models only, glandular breast tissue were segmented. For each patient organ doses were estimated using Monte Carlo Methods. To investigate the utility of regional measures of scanner output, regional and organ anatomic boundaries were identified from image data and used to calculate regional and organ-specific average tube current values. From these regional and organ-specific averages, CTDIvol values, referred to as regional and organ-specific CTDIvol, were calculated for each patient. Using an approach similar to TG 204, all CTDIvol values were used to normalize simulated organ doses; and the ability of each normalized dose to correlate with patient size was investigated. Results: For all five organs, the correlations with patient size increased when organ doses were normalized by regional and organ-specific CTDIvol values. For example, when estimating dose to the liver, CTDIvol,global yielded a R2 value of 0.26, which improved to 0.77 and 0.86, when using the regional and organ-specific CTDIvol for abdomen and liver, respectively. For breast dose, the global CTDIvol yielded a R2 value of 0.08, which improved to 0.58 and 0.83, when using the regional and organ-specific CTDIvol for chest and breasts, respectively. The R2 values also increased once the thoracic models were separated for the analysis into females and males, indicating differences between genders in this region not explained by a simple measure of effective diameter. Conclusions: This work demonstrated the utility of regional and organ-specific CTDIvol as normalization factors when using TCM. It was demonstrated that CTDIvol,global is not an effective normalization factor in TCM exams where attenuation (and therefore tube current) varies considerably throughout the scan, such as abdomen/pelvis and even thorax. These exams can be more accurately assessed for dose using regional CTDIvol descriptors that account for local variations in scanner output present when TCM is employed. PMID:23635273

Masculinity and the Body: How African-American and White Men Experience Cancer Screening Exams Involving the Rectum  

PubMed Central

Past research on prostate and colorectal cancer disparities finds that barriers to screening, such as embarrassment and offensiveness, are often reported. Yet none of this literature investigates why. This study uses masculinity and health theory to examine how men experience two common screenings, digital rectal exams (DREs) and colonoscopies. In-depth interviews were conducted with 64 African-American and white men from diverse backgrounds, aged 4064, from North Carolina, USA. Regardless of race or education, men experienced DREs more negatively than colonoscopies because penetration with a finger was associated with a gay sexual act. Some men disliked colonoscopies, however, because they associated any penetration as an affront to their masculinity. Because beliefs did not differ by race, future research should focus on structural issues to examine why disparities persist with prostate and colorectal cancer. Recommendations are provided for educational programs and physicians to improve mens experiences with exams that involve the rectum. PMID:19477742

Grading by Response Category: A simple method for providing students with meaningful feedback on exams in large courses  

NASA Astrophysics Data System (ADS)

As instructors, we want our students to develop a deep understanding of course material, and feedback is essential in their sense-making process. Providing effective individualized feedback to students in large courses is especially difficult. While researchers suggest,1 and many instructors of large courses are,2,3 incorporating interactive techniques that allow peer feedback, studies have shown that it's important for students to also have direct feedback from the instructor.4 Since the requirement for individualized feedback is difficult to meet during class time in large courses, providing effective feedback on exams and quizzes takes on added importance. Some instructors choose to assess their students using open-ended written exam items that require students to demonstrate their understanding of physics by solving a problem and/or explaining a concept. Because grading these items can be time consuming, the challenge is to develop an approach to grading and provision of feedback that is both efficient and effective.

Use of a pretest strategy for physical therapist assistant programs to predict success rate on the national physical therapy exam.  

PubMed

This study investigated a pretest strategy that identified physical therapist assistant (PTA) students who were at risk of failure on the National Physical Therapy Examination (NPTE). Program assessment data from five cohorts of PTA students (2005-2009) were used to develop a stepwise multiple regression formula that predicted first-time NPTE licensure scores. Data used included the Nelson-Denny Reading Test, grades from eight core courses, grade point average upon admission to the program, and scores from three mock NPTE exams given during the program. Pearson correlation coefficients were calculated between each of the 15 variables and NPTE scores. Stepwise multiple regression analysis was performed using data collected at the ends of the first, second, and third (final) semesters of the program. Data from the class of 2010 were then used to validate the formula. The end-of-program formula accounted for the greatest variance (57%) in predicted scores. Those students scoring below a predicted scaled score of 620 were identified to be at risk of failure of the licensure exam. These students were counseled, and a remedial plan was developed based on regression predictions prior to them sitting for the licensure exam. PMID:23752234

Role of sudarshan kriya and pranayam on lipid profile and blood cell parameters during exam stress: A randomized controlled trial  

PubMed Central

Background: Yoga is a science practiced in India over thousands of years. It produces constituent physiological changes and has sound scientific basis. Aim: Since exam stress modifies lipid profile and hematological parameters, we conducted an investigation on the effect of sudarshan kriya (SK and P) program on these parameters. Materials and Methods: Blood samples of 43 engineering students were collected at four intervals namely baseline (BL), exam stress (ES), three and six weeks practice of SK and P during exam stress. Lipid profile and hematological parameters were measured at all four intervals. Results: ES elevated total cholesterol (TC), triglycerides (TGL) and very low density lipoprotein (VLDL) levels. Hematological parameters affected by ES included neutrophil, lymphocytes, platelet count, packed cell volume (PCV) and mean cell volume (MCV). Three and six weeks practice of SK and P reduced the elevated lipid profile, hematological parameters and improved lymphocyte levels. Conclusion: Our study indicates that SK and P practice has the potential to overcome ES by improving lipid profile and hematological parameters. PMID:22346062

Predicting NCLEX-RN success with the HESI Exit Exam: eighth validity study.  

PubMed

Increasingly, Elsevier's HESI Exit Exam (E(2)) is being used to assess students' readiness for the National Council Licensure Examination for Registered Nurses (NCLEX-RN). Seven previously conducted validity studies indicate that the E(2) is 96.36%-99.16% accurate in predicting NCLEX-RN success. Findings of this eighth validity study, which also investigated the predictive accuracy of repeat testing with parallel versions of the E(2), indicated that the E(2) is highly accurate (94.93%-98.32%) in predicting NCLEX-RN success for the initial testing and 2 retests. Of the 66 participating nursing programs, deans and directors from 43 (65.15%) of the programs reported implementing a policy that used E(2) scores as a benchmark for remediation. A score of 850 was the most common E(2) benchmark designated by faculties, and students who failed to achieve the faculty-designated E(2) benchmark score were required to retest with a parallel version of the E(2). Remediation resources used to assist students in achieving faculty-designated E(2) benchmark scores varied widely, with many programs employing multiple remediation methods. PMID:23566508

The Heme-Based Oxygen-Sensor Phosphodiesterase Ec DOS (DosP): Structure-Function Relationships  

PubMed Central

Escherichia coli Direct Oxygen Sensor (Ec DOS, also known as Ec DosP) is a heme-based O2-sensing phosphodiesterase from Escherichia coli that catalyzes the conversion of cyclic-di-GMP to linear di-GMP. Cyclic-di-GMP is an important second messenger in bacteria, highlighting the importance of understanding structure-function relationships of Ec DOS. Ec DOS is composed of an N-terminal heme-bound O2-sensing PAS domain and a C-terminal phosphodiesterase catalytic domain. Notably, its activity is markedly enhanced by O2 binding to the heme Fe(II) complex in the PAS sensor domain. X-ray crystal structures and spectroscopic and catalytic characterization of the wild-type and mutant proteins have provided important structural and functional clues to understanding the molecular mechanism of intramolecular catalytic regulation by O2 binding. This review summarizes the intriguing findings that have obtained for Ec DOS. PMID:25586128

Resist DoS attacks in UMTS-WLAN  

NASA Astrophysics Data System (ADS)

Wireless network is more vulnerable to denial of service (DoS) attacks than wired one. In this paper we propose two methods to resist DoS attacks in UMTS-WLAN network, one is active and the other is passive. These two are complementary to each other. In active DoS defense method, a mobile terminal generates an authorized anonymous ID (AAI) using its true ID such as IP address, MAC address, PIN code, or asymmetric key, and substitutes its true ID with the authorized anonymous ID. The mobile terminal may be authenticated by the UMTS-WLAN, however its true ID is anonymous to intending attackers. This method can be used to isolate de-authenticating/disassociating DoS attackers, spoofing power-save DoS attacker, etc. In passive DoS defense method, we propose a trace back scheme. We use covert channels in the header of mobile IP packets to trace back the malicious nodes by embedding some address information of intermediate nodes, and recovering the embedded information by the victim. After the victim successfully traces the attacking paths from malicious nodes, it can segregate the malicious nodes and protect itself. This method can be used to resist DoS attacks of mass-produced junk message congestions.

Physical Exam and Self-Reported Pain Outcomes from a Randomized Trial on Chronic Cervicogenic Headache  

PubMed Central

Objective Objective clinical measures for use as surrogate markers of cervicogenic headache (CGH) pain have not been established. In this analysis, we investigate relationships between objective physical exam (PE) measures with self-reported CGH outcomes. Methods This is an exploratory analysis of data generated by attention control PE from an open-label randomized clinical trial. Forty of 80 subjects were randomized to 8 treatments (spinal manipulative therapy or light massage control) and 8 PE over 8 weeks. The remaining subjects received no PE. PE included motion palpation of the cervical and upper thoracic regions, active cervical range of motion (ROM) and associated pain, and algometric pain threshold evaluated over articular pillars. Self-reported outcomes included CGH and neck pain and disability, number of CGH headaches, and related disability days. Associations between PE and self-reported outcomes were evaluated using generalized linear models, adjusting for socio-demographic differences and study group. Results At baseline, number of CGH and disability days were strongly associated with cervical active ROM (p <.001 to .037). Neck pain and disability were strongly associated with ROM-elicited pain (p <.001 to .035) but not later in the study. After the final treatment, pain thresholds were strongly associated with week 12 neck pain and disability and CGH disability and disability days (p =<.001 to .048). Conclusions Cervical ROM was most associated with the baseline headache experience. However, 4 weeks after treatment, algometric pain thresholds were most associated. No one PE measure remained associated with the self-reported headache outcomes over time. PMID:20605552

OptaDOS - a new tool for EELS calculations  

NASA Astrophysics Data System (ADS)

Many modern (Scanning) Transmission Electron Microscopes ((S)TEMs) are equipped with an energy loss spectrometer. The Electron Energy Loss (EEL) spectra collected provide an experimental method of probing the bonding within a material. With the extra addition of monochromators, the energy resolution obtainable means that even more information is revealed within the fine structure of the spectra. Interpreting the fine structure can often be aided by simulation. Density-functional theory (DFT) is one method of simulating EEL spectra. DFT allows us to simulate DOS and EEL spectra from different structures. This comparison between simulation and experiment enables us to explore how changes in the spectrum are related to changes within the sample. CASTEP is a pseudopotential DFT code which can simulate both low-loss and core-loss EEL spectra. Recent developments have resulted in a separate analysis tool, OptaDOS. This package computes various spectral properties including DOS, projected DOS, joint DOS, core-loss and low-loss EEL spectra and optical spectra. One of the important aspects of the code is the way in which the DOS is calculated. This is done via linear extrapolation or adaptive smearing, methods which are not currently available within CASTEP (or indeed any other code) and which allow detailed analysis of spectral properties. This paper summarises these developments and what they mean for the interpretation of EEL spectra.

Increasing Neuroradiology Exam Volumes On-Call Do Not Result in Increased Major Discrepancies in Primary Reads Performed by Residents  

PubMed Central

Background and Purpose: A common perception is that increased on-call workload leads to increased resident mistakes. To test this, we evaluated whether increased imaging volume has led to increased errors by residents. Materials and Methods: A retrospective review was made of all overnight neuroradiology CT exams with a primary resident read from 2006-2010. All studies were over-read by staff neuroradiologists next morning. As the volume is higher on Friday through Sunday nights, weekend studies were examined separately. Discrepancies were classified as either minor or major. Major discrepancy was defined as a discrepancy that the staff radiologist felt was significant enough to potentially affect patient care, necessitating a corrected report and phone contact with the ordering physician and documentation. The total number of major discrepancies was recorded by quarter. In addition, the total number of neuroradiology CT studies read overnight on-call was noted. Results: The mean number of cases per night during the weekday increased from 3.0 in 2006 to 5.2 in 2010 (p<0.001). During the weekend, the mean number of cases per night increased from 5.4 in 2006 to 7.6 in 2010 (p<0.001). Despite this increase, the major discrepancy rate decreased from 2.7% in 2006 to 2.3% in 2010 (p=0.34). Conclusion: Despite an increase in neuroradiology exam volumes, there continues to be a low major discrepancy rate for primary resident interpretations. While continued surveillance of on-call volumes is crucial to the educational environment, concern of increased major errors should not be used as sole justification to limit autonomy.

Cellular and humoral immunity, mood and exam stress: the influences of self-hypnosis and personality predictors.  

PubMed

The effects of self-hypnosis training on immune function and mood were examined in medical students at exam time. Hypnosis involved relaxation and imagery directed at improved immune function and increased energy, alertness and concentration. Hypotheses were made about activated and withdrawn personality differences. Eight high and eight low hypnotically susceptible participants were given 10 sessions of hypnosis, one live and nine tape-recorded, and were compared with control subjects (N=12). CD3, CD4, CD8, CD19 and CD56 NK cells and blood cortisol were assayed. Life-style, activated vs. withdrawn temperament, arousal and anxiety questionnaires were administered. Self-hypnosis buffered the decline found in controls in NK (P<0.002) and CD8 cells (P<0.0.07) and CD8/CD4% (P<0.06) (45-35% order of magnitude differences) while there was an increase in cortisol (P<0.05). The change in NK cell counts correlated positively with changes in both CD8 cells and cortisol. Results were independent of changes in life-style. Energy ratings were higher after hypnosis (P<0.01), and increased calmness with hypnosis correlated with an increase in CD4 counts (P<0.01). The activated temperament, notably the cognitive subscale (speaking and thinking quickly), was predictive of exam levels of T and B lymphocytes (P&z.Lt;0.08-P<0.02), and reaching r=0.72 (P<0.001) in the non-intervention control group. The sizeable influences on cell-mediated immunity achieved by a relatively brief, low cost psychological intervention in the face of a compelling, but routine, stress in young, healthy adults have implications for illness prevention and for patients with compromised immunity.

The effect of the Advanced Placement Training and Incentive Program on increasing enrollment and performance on Advanced Placement science exams  

NASA Astrophysics Data System (ADS)

The purpose of this study is to examine the effectiveness of the National Math and Science Initiative's Advanced Placement Training and Incentive Program (APTIP) on the number of students taking AP science courses and their performance. The study evaluated 39 schools over a six-year period in six states that participate in the APTIP. The National Math and Science Initiative provided data for cohort I. A general linear model for repeated measures was used to evaluate the data. Data was evaluated three years prior to the intervention and three years during the intervention, which will actually continue for two more years (2012 and 2013) since cohort I schools were awarded five years of support. Students in APTIP schools enrolled in more AP science exams (AP Biology, AP Chemistry, AP Environmental Science, and AP Physics-B) over the course of the intervention. The quantity of students earning qualifying scores increased during the intervention years. APTIP is a multi-tiered program that includes seven days of teacher training, three six-hour student prep sessions, school equipment, reduced exam fees, and monetary incentives for students and teachers. This program positively impacted the quantity of enrollment and qualifying scores during the three years evaluated in this study. Increases in the number of female and African American students' test takers their and qualifying scores were seen in all three years of the APTIP intervention. This study supports the premise that the first step to increasing the Science, technology, engineering, and math (STEM) pipeline is giving access to advanced courses to more students in high schools.

Impact of the clinical ultrasound elective course on retention of anatomical knowledge by second-year medical students in preparation for board exams.  

PubMed

Ultrasound has been integrated into a gross anatomy course taught during the first year at an osteopathic medical school. A clinical ultrasound elective course was developed to continue ultrasound training during the second year of medical school. The purpose of this study was to evaluate the impact of this elective course on the understanding of normal anatomy by second-year students. An anatomy exam was administered to students enrolled in the clinical ultrasound elective course before the start of the course and after its conclusion. Wilcoxon signed ranks tests were used to determine whether exam scores changed from the pre-test to the post-test. Scores from two classes of second-year students were analyzed. Students who took the elective course showed significant improvement in the overall anatomy exam score between the pre-test and post-test (P < 0.001). Scores for exam questions pertaining to the heart, abdomen, upper extremity, and lower extremity also significantly improved from the pretest to post-test (P < 0.001), but scores for the neck and eye showed no significant improvement. The clinical ultrasound elective course offered during the second year of medical school provided students with an important review of key anatomical concepts while preparing them for board exams. Our results suggested that more emphasis should be placed on head and neck ultrasound to improve student performance in those areas. Musculoskeletal, abdominal, and heart ultrasound labs were more successful for retaining relevant anatomical information. Clin. Anat. 28:156-163, 2015. 2014 Wiley Periodicals, Inc. PMID:25534185

Ultrafast ligand dynamics in the heme-based GAF sensor domains of the histidine kinases DosS and DosT from Mycobacterium tuberculosis  

PubMed Central

The transcriptional regulator DosR from M. tuberculosis plays a crucial role in the virulence to dormancy transition of the pathogen. DosR can be activated by DosT and DosS, two histidine kinases with heme-containing sensor GAF domains, capable of diatomic ligand binding, To investigate the initial processes occurring upon ligand dissociation, we performed ultrafast time-resolved absorption spectroscopy of the isolated sensor domains ligated with O2, NO and CO. The results reveal a relatively closed heme pocket for both proteins. For DosT the yield of O2 escape from the heme pocket on the picoseconds timescale upon photodissociation was found to be very low (1.5%), similar to other heme-based oxygen sensor proteins, implying that this sensor acts as an effective O2 trap. Remarkably, this yield is an order of magnitude higher in DosS (18%). For CO, by contrast, the fraction of CO rebinding within the heme pocket is higher in DosS. Experiments with mutant DosT sensor domains and molecular dynamics simulations indicate an important role in ligand discrimination of the distal tyrosine, present in both proteins, which forms a hydrogen bond with heme-bound O2. We conclude that despite their similarity, DosT and DosS display ligand-specific different primary dynamics during the initial phases of intra-protein signaling. The distal tyrosine, present in both proteins, plays an important role in these processes. PMID:22142262

Structures of Mycobacterium tuberculosis DosR and DosR?DNA Complex Involved in Gene Activation during Adaptation to Hypoxic Latency  

SciTech Connect

On encountering low oxygen conditions, DosR activates the transcription of 47 genes, promoting long-term survival of Mycobacterium tuberculosis in a non-replicating state. Here, we report the crystal structures of the DosR C-terminal domain and its complex with a consensus DNA sequence of the hypoxia-induced gene promoter. The DosR C-terminal domain contains four {alpha}-helices and forms tetramers consisting of two dimers with non-intersecting dyads. In the DNA-bound structure, each DosR C-terminal domain in a dimer places its DNA-binding helix deep into the major groove, causing two bends in the DNA. DosR makes numerous protein-DNA base contacts using only three amino acid residues per subunit: Lys179, Lys182, and Asn183. The DosR tetramer is unique among response regulators with known structures.

Melanoma Screening by Means of Complete Skin Exams for All Patients in a Dermatology Practice Reduces the Thickness of Primary Melanomas at Diagnosis  

PubMed Central

Objective: Previous studies have shown that dermatologists detect thinner melanomas than both non-dermatologists and patients in high incidence areas. The authors report depths of melanomas in a central New York practice where the incidence is low, hypothesizing that incidental melanomas detected by a dermatologist will be thinner than melanomas that are part of the chief complaint. Design: A retrospective chart review examining melanoma depth to determine the importance of universal full skin exams. Setting: Private dermatology clinic in Auburn, New York, employing one board-certified dermatologist and two physician extenders. Participants: Men and women who attended the clinic between 2003 and 2013 who had 235 biopsy-proven melanomas. Total patient visits in this time period was 50,699. Measurements: Office notes were reviewed to determine the chief complaint, patient demographics, and depth of the tumor. The authors noted if the melanoma was discovered by the patient, a referring physician, dermatology physician extender, or the dermatologist. Results: More than 45 percent of melanomas were an incidental finding on full skin exam. The dermatologist detected statistically thinner melanomas than melanomas that presented as the chief complaint. The dermatologist tended to detect thinner melanomas than referring physicians and patients. Conclusion: A significant portion of melanomas are incidentally found on full skin exam, and thinner melanomas are detected by dermatologists. Universal skin cancer screening takes little additional time, and appropriate use of physician extenders can greatly increase access to dermatological care. Full skin exams increase melanoma detection, decreases overall thickness at diagnosis, and decreases patient morbidity and mortality. PMID:25161756

Detection of DoS attacks using intrusion detection sensors  

NASA Astrophysics Data System (ADS)

Intrusion detection systems have usually been developed using large host-based components. These components impose an extra load on the system where they run (sometimes even requiring a dedicated system) and are subject to tampering or disabling by an intruder. Additionally, intrusion detection systems have usually obtained information about host behavior through indirect means, such as audit trails or network packet traces. This potentially allows intruders to modify the information before the intrusion detection system obtains it and slows down the detection and prevention of DoS attacks, making it possible for an intruder to hide his activities. In this paper we propose work that will attempt to show that it is possible to perform intrusion detection mechanism of DoS attacks using small sensors embedded in a computer system. These sensors will look for signs of specific intrusions. They will perform target monitoring by observing the behavior of the through an audit trail or other indirect means in real time while the Snort IDS running. Furthermore, by being built into the computer system it could provide a flexible alert sensor which may not impose a considerable extra load on the host they monitor.

Impact of Two Types of Internet-based Information on Medical Students Performance in an Objective Structured Clinical Exam (OSCE)  

PubMed Central

Objectives Internet-based information has potential to impact physician-patient relationships. This study examined medical students interpretation and response to such information presented during an objective clinical examination. Method Ninety three medical students who had received training for a patient centered response to inquiries about alternative treatments completed a comprehensive examination in their third year. In one of twelve objective structured clinical exams, a SP presented internet-based information on l-theanine an amino acid available as a supplement. In Condition A, materials were from commercial websites; in Condition B, materials were from the PubMed website. Results Analyses revealed no significant differences between Conditions in student performance or patient (SP) satisfaction. Students in Condition A rated the information less compelling than students in Condition B (z = ?1.78, p = .037), and attributed less of the treatments action to real vs. placebo effects (z = ?1.61, p = .053). Conclusions Students trained in a patient centered response to inquiries about alternative treatment perceived the credibility of the two types of internet-based information differently but were able to respond to the patient without jeopardizing patient satisfaction. Approach to information was superficial. Training in information evaluation may be warranted. PMID:19157760

Patient portal doldrums: does an exam room promotional video during an office visit increase patient portal registrations and portal use?  

PubMed Central

The patient portal is a web service which allows patients to view their electronic health record, communicate online with their care teams, and manage healthcare appointments and medications. Despite advantages of the patient portal, registrations for portal use have often been slow. Using a secure video system on our existing exam room electronic health record displays during regular office visits, the authors showed patients a video which promoted use of the patient portal. The authors compared portal registrations and portal use following the video to providing a paper instruction sheet and to a control (no additional portal promotion). From the 12?050 office appointments examined, portal registrations within 45?days of the appointment were 11.7%, 7.1%, and 2.5% for video, paper instructions, and control respectively (p<0.0001). Within 6?months following the interventions, 3.5% in the video cohort, 1.2% in the paper, and 0.75% of the control patients demonstrated portal use by initiating portal messages to their providers (p<0.0001).

Document image archive transfer from DOS to UNIX  

NASA Technical Reports Server (NTRS)

An R&D division of the National Library of Medicine has developed a prototype system for automated document image delivery as an adjunct to the labor-intensive manual interlibrary loan service of the library. The document image archive is implemented by a PC controlled bank of optical disk drives which use 12 inch WORM platters containing bitmapped images of over 200,000 pages of medical journals. Following three years of routine operation which resulted in serving patrons with articles both by mail and fax, an effort is underway to relocate the storage environment from the DOS-based system to a UNIX-based jukebox whose magneto-optical erasable 5 1/4 inch platters hold the images. This paper describes the deficiencies of the current storage system, the design issues of modifying several modules in the system, the alternatives proposed and the tradeoffs involved.

Increasing time to operation is associated with decreased survival in patients with a positive FAST exam requiring emergent laparotomy  

PubMed Central

Introduction Focused assessment with sonography for trauma (FAST) is commonly used to facilitate the timely diagnosis of life threatening hemorrhage in injured patients. Most patients with positive findings on FAST require laparotomy. Though it is assumed that an increasing time to operation leads to higher mortality, this relationship has not been quantified. This study sought to determine the impact of time to operation (T-OR) on survival in patients with a positive FAST that required emergent laparotomy. Methods We retrospectively analyzed patients from the Prospective Observational Multicenter Major Trauma Transfusion (PROMMTT) study that underwent laparotomy within 90 minutes of presentation and had a FAST performed. Cox proportional hazards models including Injury Severity Score (ISS), age, base deficit and hospital site were created to examine the impact of increasing T-OR on in-hospital survival at 24 hours and 30 days. The impact of time from the performance of the FAST exam to operation (TFAST-OR) on in-hospital mortality was also examined using the same model. Results One hundred and fifteen patients met study criteria and had complete data. Increasing T-OR was associated with increased in-hospital mortality at 24 hours (hazard ratio [HR] 1.50 for each 10 minute increase in T-OR, confidence interval [CI] 1.14-1.97, p = 0.003) and 30 days (HR 1.41, CI 1.18-2.10, p = 0.002). Increasing TFAST-OR was also associated with higher in-hospital mortality at 24 hours (HR 1.34, CI 1.03-1.72, p = 0.03) and 30 days (HR 1.40, CI 1.06-1.84, p = 0.02). Conclusion In patients with a positive FAST who required emergent laparotomy, delay in operation was associated with increased early and late in-hospital mortality. Delays in time to operation in trauma patients with a positive FAST should be minimized. PMID:23778511

Certified records manager exam  

SciTech Connect

The Institute of Certified Records Managers (ICRM) is a non-profit, certifying organization of professional records managers and administrators. ICRM members are experienced in information requirements, records and information systems, and the related office systems and technologies. All members have met certification requirements and have received the Certified Records Manager (CRM) designation. As the field of information and records management moves toward standardization, and as the application of new technologies and technicalities complicate the measurement and demonstration of professional competence, the need for a means of identifying persons who have basic competency increases. The ICRM is providing such a means by testing and certifying basic knowledge. More and more job announcements are requiring this evidence of competency. Unfortunately, as an organization, NIRMA has a relatively small number of CRMs. The goal of the ICRM Development Group is two-fold; (1) to encourage NIRMA members to obtain their certification by providing basic information and support and; (2) to develop the Nuclear Specialist test module which will demonstrate that bearers have demonstrated expertise in nuclear records management as well as basic competencies. This report covers the examination process.

Queda dos homicdios em So Paulo, Brasil: uma anlise descritiva  

PubMed Central

Objetivo Descrever a evoluo da mortalidade por homicdios no Municpio de So Paulo segundo tipo de arma, sexo, raa ou cor, idade e reas de excluso/incluso social entre 1996 e 2008. Mtodos Estudo ecolgico de srie temporal. Os dados sobre bitos ocorridos no Municpio foram coletados da base de dados do Programa de Aprimoramento das Informaes sobre Mortalidade, seguindo a Classificao Internacional de Doenas, Dcima Reviso (CID-10). Foram calculadas as taxas de mortalidade por homicdio (TMH) para a populao total, por sexo, raa ou cor, faixa etria, tipo de arma e rea de excluso/incluso social. As TMH foram padronizadas por idade pelo mtodo direto. Foram calculados os percentuais de variao no perodo estudado. Para as reas de excluso/incluso social foram calculados os riscos relativos de morte por homicdio. Resultados As TMH apresentaram queda de 73,7% entre 2001 e 2008. Foi observada reduo da TMH em todos os grupos analisados, mais pronunciada em homens (?74,5%), jovens de 15 a 24 anos (?78,0%) e moradores de reas de excluso social extrema (?79,3%). A reduo ocorreu, sobretudo, nos homicdios cometidos com armas de fogo (?74,1%). O risco relativo de morte por homicdio nas reas de excluso extrema (tendo como referncia reas com algum grau de excluso social) foi de 2,77 em 1996, 3,9 em 2001 e 2,13 em 2008. Nas reas de alta excluso social, o risco relativo foi de 2,07 em 1996 e 1,96 em 2008. Concluses Para compreender a reduo dos homicdios no Municpio, importante considerar macrodeterminantes que atingem todo o Municpio e todos os subgrupos populacionais e microdeterminantes que atuam localmente, influenciando de forma diferenciada os homicdios com armas de fogo e os homicdios na populao jovem, no sexo masculino e em residentes em reas de alta excluso social.

The Dormancy Regulator DosR Controls Ribosome Stability in Hypoxic Mycobacteria*  

PubMed Central

It is thought that during latent infection, Mycobacterium tuberculosis bacilli are retained within granulomas in a low-oxygen environment. The dormancy survival (Dos) regulon, regulated by the response regulator DosR, appears to be essential for hypoxic survival in M. tuberculosis, but it is not known how the regulon promotes survival. Here we report that mycobacteria, in contrast to enteric bacteria, do not form higher-order structures (e.g. ribosomal dimers) upon entry into stasis. Instead, ribosomes are stabilized in the associated form (70S). Using a strategy incorporating microfluidic, proteomic, and ribosomal profiling techniques to elucidate the fate of mycobacterial ribosomes during hypoxic stasis, we show that the dormancy regulator DosR is required for optimal ribosome stabilization. We present evidence that the majority of this effect is mediated by the DosR-regulated protein MSMEG_3935 (a S30AE domain protein), which is associated with the ribosome under hypoxic conditions. A ?3935 mutant phenocopies the ?dosR mutant during hypoxia, and complementation of ?dosR with the MSMEG_3935 gene leads to complete recovery of dosR mutant phenotypes during hypoxia. We suggest that this protein is named ribosome-associated factor under hypoxia (RafH) and that it is the major factor responsible for DosR-mediated hypoxic survival in mycobacteria. PMID:22544737

The pre-health collection within MedEdPORTAL's iCollaborative: helping faculty prepare students for the competencies in the new MCAT(2015) exam.  

PubMed

To help faculty prepare and revise courses in all the disciplines represented in the MCAT(2015) , the American Association of Medical Colleges, through its MedEdPORTAL's iCollaborative, has established the Pre-health Collection, a repository of reviewed web resources that are openly and freely available to faculty, and indirectly through them to students. The Pre-health Collection initiative makes use of the Internet to centralize teaching resources and to help faculty at institutions with fewer available resources to incorporate high quality teaching material specifically reviewed to assist students in obtaining the required pre-health competencies. As biochemistry competencies are increasingly represented in the new exam, it is important to grow the number of quality teaching resources for biochemistry within the portal and to develop a community of users and contributors. A description of the Pre-Health Collection and mechanisms for contributions are presented. PMID:23381886

Measurements of degree of sensitization (DoS) in aluminum alloys using EMAT ultrasound.  

PubMed

Sensitization in 5XXX aluminum alloys is an insidious problem characterized by the gradual formation and growth of beta phase (Mg(2)Al(3)) at grain boundaries, which increases the susceptibility of alloys to intergranular corrosion (IGC) and intergranular stress-corrosion cracking (IGSCC). The degree of sensitization (DoS) is currently quantified by the ASTM G67 Nitric Acid Mass Loss Test, which is destructive and time consuming. A fast, reliable, and non-destructive method for rapid detection and the assessment of the condition of DoS in AA5XXX aluminum alloys in the field is highly desirable. In this paper, we describe a non-destructive method for measurements of DoS in aluminum alloys with an electromagnetic acoustic transducer (EMAT). AA5083 aluminum alloy samples were sensitized at 100C with processing times varying from 7days to 30days. The DoS of sensitized samples was first quantified with the ASTM 67 test in the laboratory. Both ultrasonic velocity and attenuation in sensitized specimens were then measured using EMAT and the results were correlated with the DoS data. We found that the longitudinal wave velocity was almost a constant, independent of the sensitization, which suggests that the longitudinal wave can be used to determine the sample thickness. The shear wave velocity and especially the shear wave attenuation are sensitive to DoS. Relationships between DoS and the shear velocity, as well as the shear attenuation have been established. Finally, we performed the data mining to evaluate and improve the accuracy in the measurements of DoS in aluminum alloys with EMAT. PMID:21232777

Phosphodiesterase DosP increases persistence by reducing cAMP which reduces the signal indole.  

PubMed

Persisters are bacteria that are highly tolerant to antibiotics due to their dormant state and are of clinical significance owing to their role in infections. Given that the population of persisters increases in biofilms and that cyclic diguanylate (c-di-GMP) is an intracellular signal that increases biofilm formation, we sought to determine whether c-di-GMP has a role in bacterial persistence. By examining the effect of 30 genes from Escherichia coli, including diguanylate cyclases that synthesize c-di-GMP and phosphodiesterases that breakdown c-di-GMP, we determined that DosP (direct oxygen sensing phosphodiesterase) increases persistence by over a thousand fold. Using both transcriptomic and proteomic approaches, we determined that DosP increases persistence by decreasing tryptophanase activity and thus indole. Corroborating this effect, addition of indole reduced persistence. Despite the role of DosP as a c-di-GMP phosphodiesterase, the decrease in tryptophanase activity was found to be a result of cyclic adenosine monophosphate (cAMP) phosphodiesterase activity. Corroborating this result, the reduction of cAMP via CpdA, a cAMP-specific phosphodiesterase, increased persistence and reduced indole levels similarly to DosP. Therefore, phosphodiesterase DosP increases persistence by reducing the interkingdom signal indole via reduction of the global regulator cAMP. Biotechnol.

The relationship between selected standardized test scores and performance in advanced placement math and science exams: Analyzing the differential effectiveness of scores for course identification and placement  

NASA Astrophysics Data System (ADS)

There is a national need to increase the STEM-related workforce. Among factors leading towards STEM careers include the number of advanced high school mathematics and science courses students complete. Florida's enrollment patterns in STEM-related Advanced Placement (AP) courses, however, reveal that only a small percentage of students enroll into these classes. Therefore, screening tools are needed to find more students for these courses, who are academically ready, yet have not been identified. The purpose of this study was to investigate the extent to which scores from a national standardized test, Preliminary Scholastic Assessment Test/ National Merit Qualifying Test (PSAT/NMSQT), in conjunction with and compared to a state-mandated standardized test, Florida Comprehensive Assessment Test (FCAT), are related to selected AP exam performance in Seminole County Public Schools. An ex post facto correlational study was conducted using 6,189 student records from the 2010 - 2012 academic years. Multiple regression analyses using simultaneous Full Model testing showed differential moderate to strong relationships between scores in eight of the nine AP courses (i.e., Biology, Environmental Science, Chemistry, Physics B, Physics C Electrical, Physics C Mechanical, Statistics, Calculus AB and BC) examined. For example, the significant unique contribution to overall variance in AP scores was a linear combination of PSAT Math (M), Critical Reading (CR) and FCAT Reading (R) for Biology and Environmental Science. Moderate relationships for Chemistry included a linear combination of PSAT M, W (Writing) and FCAT M; a combination of FCAT M and PSAT M was most significantly associated with Calculus AB performance. These findings have implications for both research and practice. FCAT scores, in conjunction with PSAT scores, can potentially be used for specific STEM-related AP courses, as part of a systematic approach towards AP course identification and placement. For courses with moderate to strong relationships, validation studies and development of expectancy tables, which estimate the probability of successful performance on these AP exams, are recommended. Also, findings established a need to examine other related research issues including, but not limited to, extensive longitudinal studies and analyses of other available or prospective standardized test scores.

Computer-Based Internet-Hosted Assessment of L2 Literacy: Computerizing and Administering of the Oxford Quick Placement Test in ExamView and Moodle  

NASA Astrophysics Data System (ADS)

Sorting of Korean English-as-a-Foreign-Language (EFL) university students by Second Language (L2) aptitude allocates students to classes of compatible ability level, and was here used to screen candidates for interview. Paper-and-pen versions of the Oxford Quick Placement Test were adapted to computer-based testing via online hosting using FSCreations ExamView. Problems with their online hosting site led to conversion to the popular computer-based learning management system Moodle, hosted on www.ninehub.com. 317 sophomores were tested online to encourage L2 digital literacy. Strategies for effective hybrid implementation of Learning Management Systems in L2 tertiary education include computer-based Internet-hosted L2 aptitude tests. These potentially provide a convenient measure of student progress in developing L2 fluency, and offer a more objective and relevant means of teacher- and course-assessment than student evaluations, which tend to confuse entertainment value and teacher popularity with academic credibility and pedagogical effectiveness.

Qual o Papel da Escola e da Mdia na Obteno dos Conhecimentos Astronmicos?  

NASA Astrophysics Data System (ADS)

amplamente reconhecido que as pessoas em geral tm grande fascnio e interesse pela Astronomia. Por outro lado, o contedo dessa rea includo no ensino formal est longe de ser abrangente e suficiente para suprir a demanda. Esse interesse permite aperfeioar a divulgao e o ensino no formal de Astronomia atravs da mdia aliando a adequao do contedo expectativa das pessoas. A reforma do Currculo Bsico da Escola Pblica da maioria dos Estados brasileiros tem introduzido Astronomia desde a pr-escola at o Ensino Mdio. Num estudo realizado com 1180 alunos do Ensino Mdio de seis escolas estaduais, revelou-se atravs da aplicao de um formulrio contendo questes que abordavam conhecimentos bsicos em Astronomia, como foram adquiridos tais conhecimentos e infra-estrutura da escola. Para 66,1% dos entrevistados o professor j fez alguma apresentao a respeito de Astronomia. O presente estudo revelou tambm que 54,4% dos alunos entrevistados adquiriram seus conhecimentos astronmicos na escola, 18,4% atravs da televiso e 27,1% afirmaram que seus conhecimentos foram obtidos atravs de outros tipos de mdia (internet, livros didticos, filmes e revistas). Embora o estudo revele claramente que h certo equilbrio no meio em que os alunos obtiveram seus conhecimentos astronmicos, a mdia busca no somente sua difuso, mas a disponibilizao desse conhecimento de maneira correta, que s vezes, no atingido, apresentando conceitos sem fundamentao e incorretos. Por outro lado, no dia-a-dia escolar, comum encontrar professores que vm para as aulas com concepes prvias, que podem diferir substancialmente das idias a serem ensinadas, dificultando o aprendizado de futuros conceitos cientficos. Uma avaliao criteriosa, avaliando as dificuldades dos professores em determinar o sentido correto dos conceitos e observando a metodologia que utilizam no ensino, poder proporcionar uma melhor compreenso sobre as concepes alternativas, presentes no ensino de Astronomia.

A razo para o desenvolvimento deste trabalho baseia-se no fato de que muitos professores da Educao Bsica (EB) no lidam com conceitos relacionados astronomia, e quando o fazem eles simplesmente seguem livros didticos que podem conter erros conceituais. Como de conhecimento geral a astronomia um dos contedos a serem ensinados na EB fazendo parte dos Parmetros Curriculares Nacionais e das Propostas Curriculares do Estado de So Paulo, mas um fato, que vrios pesquisadores apontam, a existncia de muitos problemas no ensino da astronomia. Com o propsito de minimizar algumas dessas deficincias foi realizado um trabalho de pesquisa com a utilizao de questionrios pr e ps pesquisa, para tanto foi desenvolvido um Curso de Extenso Universitria para professores da Diretoria de Ensino Regional (DE) que abrange Mau, Ribeiro Pires e Rio Grande da Serra (no Estado de So Paulo) com os seguintes objetivos: levantar concepes alternativas; subsidiar os professores por meio de palestras, debates e workshops, e verificar o sucesso da aprendizagem aps o curso, adotando-se como referncia, para a anlise dos resultados, os dicionrios de Lngua Portuguesa (FERREIRA, 2004) e Enciclopdico de Astronomia e Astronutica (MOUR?O, 1995). Portanto, dezesseis questes foram aplicadas antes e aps o curso, assim pode-se verificar aps a pesquisa que 100,0% dos professores sabiam os nomes das fases da Lua, 97,0% entenderam que o Sistema Solar composto por oito planetas, 78,1% foram capazes de explicar como ocorre um eclipse lunar, um eclipse solar e um solstcio, 72,7% sabiam como explicar a ocorrncia das estaes do ano; 64,5% explicaram corretamente a ocorrncia do equincio, 89,7% foram capazes de definir adequadamente o termo cometa; 63,6% definiram asteride, 54,5% meteoro, 58,1% galxia, e 42,4% planeta.

Physical exam and occult post-traumatic vascular lesions: implications for the evaluation and management of arterial injuries in modern warfare in the endovascular era.  

PubMed

Based on complexity of extremity wounds sustained in recent combat, arteriography had been used routinely in evaluations for delayed or occult arterial injuries. This report aims to quantitatively analyze the sensitivity and specificity of physical exam (PE) in predicting the presence of these injuries. United States service members sustaining extremity trauma in the Global War on Terrorism were evacuated to our medical center and evaluated by a senior vascular surgeon. Those with an abnormal PE, at risk based on wounding patterns, or previously treated for vascular injury underwent arteriography. Data from each patient were prospectively entered into a Vascular Injury registry. Comprehensive information about the injuries, interventions, arteriogram results, and any periprocedural complications were analyzed. Twenty-five endovascular or open surgical interventions were performed in forty-six of 99 patients that had lesions on arteriography. Seventy-three patients had a normal PE, of which 36 had lesions that prompted 6 subsequent interventions. Twenty-two of 26 patients with an abnormal PE had lesions that prompted 19 interventions. For PE, sensitivity was 38%, specificity was 90%, and positive predictive value (PPV) and negative predictive value (NPV) were 85% and 51%, respectively. In proximity injuries, PPV improved to 100%, but was only 15% sensitive with a NPV of 60%. In conclusion normal PE did not reliably predict post-traumatic arterial lesions in these military extremity injuries. These lesions are amenable to endovascular therapies, and should be considered in cases of complex trauma involving high amounts of energy, penetrating mechanisms, or wounding patterns in proximity to named vessels.

Trace Element Distribution Between Olivine and Kirschsteinite in Angra Dos Reis  

NASA Technical Reports Server (NTRS)

The angrites are a small and enigmatic group of basaltic achondrites that possess unique mineralogical and chemical properties. The dominant mineralogy of the seven angrite members (Angra dos Reis, LEW 86010, LEW 87051, Asuka 881371, Sahara 99555, D Orbigny, and a new Moroccan member) is fassaite, olivine, and plagioclase. Angrites display a wide range of thermal histories, with Angra dos Reis (AdoR) exhibiting a cooling history different from that of the rapidly cooled members and from LEW86010, a more slowly cooled member. AdoR could represent either a cumulate or a porphyritic igneous rock that was later altered by metamorphism. We are re-examining the thermal history of AdoR in light of the more recently described angrite members. Our emphasis is a trace element study of low-Ca olivine, which we refer to as olivine, and high-Ca olivine, which we refer to as kirschsteinite, in AdoR.

Isotope ratios and age estimations are presented for the ultramafic pyroxenite Angra dos Reis meteorite. A pyroxene-phosphate internal isochron age of 4.55 plus or minus 0.04 eons was obtained, in agreement with reported Pb-Pb ages. It is suggested that Sm-146 decay led to an increase in the ratio of Nd-142 to Nd-144 in pyroxene, which is greater than the ratio

FlexyDos3D: a deformable anthropomorphic 3D radiation dosimeter: radiation properties.  

PubMed

Three dimensional radiation dosimetry has received growing interest with the implementation of highly conformal radiotherapy treatments. The radiotherapy community faces new challenges with the commissioning of image guided and image gated radiotherapy treatments (IGRT) and deformable image registration software.A new three dimensional anthropomorphically shaped flexible dosimeter, further called 'FlexyDos3D', has been constructed and a new fast optical scanning method has been implemented that enables scanning of irregular shaped dosimeters. The FlexyDos3D phantom can be actuated and deformed during the actual treatment. FlexyDos3D offers the additional advantage that it is easy to fabricate, is non-toxic and can be molded in an arbitrary shape with high geometrical precision.The dosimeter formulation has been optimized in terms of dose sensitivity. The influence of the casting material and oxygen concentration has also been investigated. The radiophysical properties of this new dosimeter are discussed including stability, spatial integrity, temperature dependence of the dosimeter during radiation, readout and storage, dose rate dependence and tissue equivalence.

An integrated machine learning approach for predicting DosR-regulated genes in Mycobacterium tuberculosis  

PubMed Central

Background DosR is an important regulator of the response to stress such as limited oxygen availability in Mycobacterium tuberculosis. Time course gene expression data enable us to dissect this response on the gene regulatory level. The mRNA expression profile of a regulator, however, is not necessarily a direct reflection of its activity. Knowing the transcription factor activity (TFA) can be exploited to predict novel target genes regulated by the same transcription factor. Various approaches have been proposed to reconstruct TFAs from gene expression data. Most of them capture only a first-order approximation to the complex transcriptional processes by assuming linear gene responses and linear dynamics in TFA, or ignore the temporal information in data from such systems. Results In this paper, we approach the problem of inferring dynamic hidden TFAs using Gaussian processes (GP). We are able to model dynamic TFAs and to account for both linear and nonlinear gene responses. To test the validity of the proposed approach, we reconstruct the hidden TFA of p53, a tumour suppressor activated by DNA damage, using published time course gene expression data. Our reconstructed TFA is closer to the experimentally determined profile of p53 concentration than that from the original study. We then apply the model to time course gene expression data obtained from chemostat cultures of M. tuberculosis under reduced oxygen availability. After estimation of the TFA of DosR based on a number of known target genes using the GP model, we predict novel DosR-regulated genes: the parameters of the model are interpreted as relevance parameters indicating an existing functional relationship between TFA and gene expression. We further improve the prediction by integrating promoter sequence information in a logistic regression model. Apart from the documented DosR-regulated genes, our prediction yields ten novel genes under direct control of DosR. Conclusions Chemostat cultures are an ideal experimental system for controlling noise and variability when monitoring the response of bacterial organisms such as M. tuberculosis to finely controlled changes in culture conditions and available metabolites. Nonlinear hidden TFA dynamics of regulators can be reconstructed remarkably well with Gaussian processes from such data. Moreover, estimated parameters of the GP can be used to assess whether a gene is controlled by the reconstructed TFA or not. It is straightforward to combine these parameters with further information, such as the presence of binding motifs, to increase prediction accuracy. PMID:20356371

Crystal Structures of the Response Regulator DosR from Mycobacterium tuberculosis Suggest a Helix Rearrangement Mechanism for Phosphorylation Activation  

PubMed Central

The response regulator DosR is essential for promoting long-term survival of Mycobacterium tuberculosis under low oxygen conditions in a dormant state and may be responsible for latent tuberculosis in one third of the worlds population. Here we report crystal structures of full-length unphosphorylated DosR at 2.2 and its C-terminal DNA-binding domain at 1.7 resolution. The full-length DosR structure reveals several features never seen before in other response regulators. The N-terminal domain of the full-length DosR structure has an unexpected (??)4 topology instead of the canonical (??)5 fold observed in other response regulators. The linker region adopts a unique conformation which contains two helices forming a four-helix bundle with two helices from another subunit, resulting in dimer formation. The C-terminal domain in the full-length DosR structure displays a novel location of helix ?10 which provides Gln199 to interact with the catalytic Asp54 residue of the N-terminal domain. In contrast, the structure of the DosR C-terminal domain alone displays a remarkable unstructured conformation for helix ?10 residues different from the well-defined helical conformations in all other known structures, indicating considerable flexibility within the C-terminal domain. Our structures suggest a mode of DosR activation by phosphorylation via a helix rearrangement mechanism. PMID:18353359

DoS detection in IEEE 802.11 with the presence of hidden nodes.  

PubMed

The paper presents a novel technique to detect Denial of Service (DoS) attacks applied by misbehaving nodes in wireless networks with the presence of hidden nodes employing the widely used IEEE 802.11 Distributed Coordination Function (DCF) protocols described in the IEEE standard [1]. Attacker nodes alter the IEEE 802.11 DCF firmware to illicitly capture the channel via elevating the probability of the average number of packets transmitted successfully using up the bandwidth share of the innocent nodes that follow the protocol standards. We obtained the theoretical network throughput by solving two-dimensional Markov Chain model as described by Bianchi [2], and Liu and Saadawi [3] to determine the channel capacity. We validated the results obtained via the theoretical computations with the results obtained by OPNET simulator [4] to define the baseline for the average attainable throughput in the channel under standard conditions where all nodes follow the standards. The main goal of the DoS attacker is to prevent the innocent nodes from accessing the channel and by capturing the channel's bandwidth. In addition, the attacker strives to appear as an innocent node that follows the standards. The protocol resides in every node to enable each node to police other nodes in its immediate wireless coverage area. All innocent nodes are able to detect and identify the DoS attacker in its wireless coverage area. We applied the protocol to two Physical Layer technologies: Direct Sequence Spread Spectrum (DSSS) and Frequency Hopping Spread Spectrum (FHSS) and the results are presented to validate the algorithm.

Volcanic and structural controls of mineralization in the Dos Cabezas Mountains of southeastern Arizona  

SciTech Connect

A combination of geophysical, geochemical, and geological features suggests that a central part of the Dos Cabezas Mountains probably has considerable potential for blind deposits, chiefly base metals. The area exposes the root zone of a Paleocene( ) volcanic complex and its underlying granitic stocks, which were emplaced next to a major northwest-trending, much reactivated fault zone. The new data, combined with the knowledge of past mining activity in the area, lead them to propose several exploration targets that may lead to ore bodies in breccia pipes along the base of the volcanic pile and along a possible concealed fault or caldera margin.

Use of Remote Sensing and Local Knowledge for Geoconservation of Regiao dos Lagos, Brazil  

NASA Astrophysics Data System (ADS)

A series of lagoons can be found along the coastline of Rio de Janeiro, in the so-called Regiao dos Lagos. The lagoons differ in size, physicochemical, sedimentological and biological characteristics. Rare examples of litifying microbialites that produce stromatolites, the oldest fossils on Earth, can be found living in this lagoon system. The occurrence of stromatolites in the region is of great scientific interest because it enables the study of possible analogues of the earliest life on Earth. However, this region has been suffering from intense human activities and degradations. Geoconservation planning requires an assessment of the characteristics of the region and its potential threats. The primary goal of this study is to assess physical environmental changes and anthropogenic impacts over the last four decades in Regiao dos Lagos. Using a broad integrative assessment combining remote sensing, GIS, field studies and local knowledge of communities, land-cover and land-use classes were identified, as well as the main human activities impacting the environment. The seasonal and weekend tourism and urban sprawl in this coastal area of Rio de Janeiro triggers the occupation of new areas and the removal of natural vegetation, especially on lagoon margins. This disorderly occupation by an ever increasing population, with both legal and illegal constructions and the subsequent overload of the local infrastructure, e.g. increase of electrical energy consumption, volume of vehicles, pollution in air, water and soil and problems with water supply and wastewater treatment, are hastening the gradual degradation of the lake ecosystem. The main driving forces to environmental changes over the last four decades in Regiao dos Lagos were the change of dense vegetation, saline and bare soil classes into built-up areas, adding to the poor waste treatment and inadequate sewage disposal. This analysis provides a basis for a better control of anthropogenic impacts and geoconservation activities of the ';Geopark Costoes e Lagunas do Rio de Janeiro', which includes Regiao dos Lagos. The goals of the geopark are the conservation of a healthy environment, education in the Earth sciences and the fostering of local, sustainable economic development. It is essential that the local government and population support the geoconservation work and are involved in the planning and implementation of activities. The local knowledge about natural, cultural and economical particularities of the region and awareness on environmental issues are taken into consideration, in order to assist the development of specific geoconservation activities according to community needs.

RighTime: A real time clock correcting program for MS-DOS-based computer systems  

NASA Technical Reports Server (NTRS)

A computer program is described which effectively eliminates the misgivings of the DOS system clock in PC/AT-class computers. RighTime is a small, sophisticated memory-resident program that automatically corrects both the DOS system clock and the hardware 'CMOS' real time clock (RTC) in real time. RighTime learns what corrections are required without operator interaction beyond the occasional accurate time set. Both warm (power on) and cool (power off) errors are corrected, usually yielding better than one part per million accuracy in the typical desktop computer with no additional hardware, and RighTime increases the system clock resolution from approximately 0.0549 second to 0.01 second. Program tools are also available which allow visualization of RighTime's actions, verification of its performance, display of its history log, and which provide data for graphing of the system clock behavior. The program has found application in a wide variety of industries, including astronomy, satellite tracking, communications, broadcasting, transportation, public utilities, manufacturing, medicine, and the military.

Wireless sensor networks are generally deployed for collecting data from various environments. Several applications specific sensor network cryptography algorithms have been proposed in research. However WSN's has many constrictions, including low computation capability, less memory, limited energy resources, vulnerability to physical capture, which enforce unique security challenges needs to make a lot of improvements. This paper presents a novel security mechanism and algorithm for wireless sensor network security and also an application of this algorithm. The proposed scheme is given to strong authentication against Denial of Service Attacks (DOS). The scheme is simulated using network simulator2 (NS2). Then this scheme is analyzed based on the network packet delivery ratio and found that throughput has improved. PMID:25106827

Data from on-board photometers and ground-based data from a Na lidar and an airglow imager allowed an estimate to be made, using both the TIME-GCM and MSIS models, of the branching coefficient ? for the Na airglow emission. Assuming the hydrogen density is within the range predicted by the two models the data are consistent with ? being less than 0.05. This value is well below a recent theoretical estimate of 0.67 and also below the nominally accepted value of 0.1 derived from previous aeronomic data.

Age and isotopic relationships among the angrites Lewis Cliff 86010 and Angra dos Reis  

NASA Technical Reports Server (NTRS)

The paper presents results of a wide-ranging isotopic investigation of the the Antarctic angrite LEW-86010 (LEW), and reassesses the type angrite Angra dos Reis (ADOR) in order to obtain precise radiometric ages and initial Sr isotopic compositions, and to search for the erstwhile presence of the short-lived nuclei Sm-146 and Al-26 via their daughter products. The isotopic compositions of Sm, U, Ca, and Ti were measured to allow a detailed appraisal to be made of the relations between, and the geneology of, these two angrites. LEW proves to be severely contaminated with modern terrestrial Pb, which is shown to result from terrestrial weathering. Concordant Pb-Pb model ages of pyroxene separates are obtained; uranium isotopic compositions are normal within error. Overall, striking age and isotopic similarities between LEW and ADOR were found, suggesting almost simultaneous production on the same asteroid, even though recent experimental studies imply that the two are not comagmatic.

Identification and seasonal variation of atmospheric organic pollutants in Campos dos Goytacazes, Brazil  

NASA Astrophysics Data System (ADS)

Organic aerosol samples collected during a 1 year study at three sites in the city of Campos dos Goytacazes, Rio de Janeiro, Brazil, were examined by gas chromatography and gas chromatography-mass spectrometry. Samples were acquired using a standard high-volume air sampler (Hi-Vol); extracts prepared and fractionated into aliphatic, aromatic and polar compounds. These compounds were quantified and their seasonal ambient concentration patterns discussed. High winter and low summer concentrations were observed for retene, polycyclic aromatic hydrocarbons and total suspended particulate matter (TSP), with a seasonal (winter) peak for all compounds studied. The higher concentrations observable from May to September may result from crop burning processes, which occur in the sugarcane plantations, mainly during this part of the year. The studied sites may be considered unpolluted as concentrations of benzo[a]pyrene and benzene were lower than the regulation lower limits. On the other hand, two sites were considered polluted by TSP determination.

A proposed application of an industrial DOS computer for distribution substation monitoring and control  

SciTech Connect

This paper presents the design and implementation of an intelligent controller intended for use in distribution substations to perform monitoring and control duties within the framework of distribution automation needs. The hardware of the developed controller is a DOS based industrial computer running on ECB-BUS. The application software handles all input/output tasks, data collection, manipulation and control decisions with its flexible structure. This embedded controller measures bus voltage, transformer and feeder currents and calculates the real and reactive power, power factor, frequency, and total harmonic distortion of voltage and current. In addition to its local and remote data acquisition and monitoring functions by means of console and SCADA outputs, the system, through its relay outputs, is capable of performing automation tasks such as integrated Volt/Var control, overload and underfrequency detection and load shedding at the substation level. This reliable, high capacity and low cost system is completely programmable so that it can handle new requirements with new configurations easily.

Creating a Global Fiducials Program (GFP) Site: Lago Cachet Dos example in Chile  

NASA Astrophysics Data System (ADS)

The USGS has been acquiring remotely sensed imagery from all over the world, collecting thousands of images at more than 200 sites, and creating Literal Image Derived Products (LIDPs) as part of the Global Fiducials Program (GFP). The GFP program enables scientists to use these images to study our rapidly changing planet at carefully selected locations around the world. New GFP Sites are created and added each year. Researchers at the University of Alaska, for instance, added areas susceptible to coastal erosion for monitoring the long-term effects of high tides and storms. This presentation will guide you through the process of creating a new GFP site for your area of interest. We will describe the components of the GFP and its archive, the Global Fiducials Library. The Global Fiducials ProgramInitial Site Proposal form will be presented and we will show you how to complete each component in order to propose a new site. Lago Cachet Dos, a glacier-dammed lake in southern Chile, is currently being proposed as a new GFP site and will be used as the example for this exercise. In addition, USGS web sites will be used to illustrate how a long-term imagery record can tell a story and to demonstrate viewing and downloading the type of data that will be available online and free of charge through the GFP.

Open Cluster Radial Velocity determination from observations at Observatrio Pico Dos Dias  

NASA Astrophysics Data System (ADS)

In studies of the dynamics of the Galactic disk, such as the determination of the speed of the spiral pattern and the permanence of stars in the spiral arms, it is crucial to know orbits obtained from proper motions, radial velocities and the potential of the Galaxy. Aiming to improve the statistics of our catalog of open clusters, maintained by our research group, we determined the radial velocity of stars belonging to a group of open clusters using spectra with a resolution of 4000, obtained at the Pico dos Dias Observatory (LNA) with the 1.60 m telescope and the Coud spectrograph. We observed the open cluster's member stars and calculated their radial speeds using standard techniques. The stars were selected from our own database based on relevant information concerning the clusters, obtained by statistical analysis of their proper motions and/or their position in the HR's diagram. In this work, we present the detailed analysis of the data reduction and radial velocity determination using synthetic spectra from different libraries. Finally we present the open cluster's radial (and spacial) velocities.

[Temporary and permanent breeding sites for Biomphalaria in Jaboato dos Guararapes, PE].  

PubMed

A malacological survey of permanent and temporary breeding sites was conducted in the Piedade neighborhood of Jaboato dos Guararapes, Pernambuco, between November 2006 and November 2007, with the aim of determining the malacological fauna at this locality, along with the potential for Schistosomiasis mansoni transmission. In addition to Biomphalaria glabrata (Say, 1818), the molluscs Drepanotrema cimex (Moricand, 1837), Pomacea sp and Melanoides tuberculatus (Muller, 1774) were collected. Among the specimens of Biomphalaria glabrata that were collected, 1,490 were found alive, and 74 (5%) were positive for Schistosoma mansoni. The largest numbers of molluscs collected, and all of the specimens that were positive for Schistosoma mansoni, were collected during the annual rainy season. The presence of larvae of other trematodes infecting the Biomphalaria glabrata molluscs was also observed. These trematodes were from the families Strigeidae and Diplostomatidae and, at first sight, they presented morphology that could lead to confusion with Schistosoma mansoni cercariae. Thus, knowledge of these trematodes becomes essential for the differential diagnosis of the etiological agent for schistosomiasis. PMID:18719804

Cross-Reactive Immunity to Mycobacterium tuberculosis DosR Regulon-Encoded Antigens in Individuals Infected with Environmental, Nontuberculous Mycobacteria?  

PubMed Central

Mycobacterium tuberculosis DosR regulon-encoded antigens are highly immunogenic in M. tuberculosis-infected humans and are associated with latent tuberculosis infection. We have investigated the hypothesis that infection with or exposure to nontuberculous mycobacteria (NTM) can induce cross-reactive immunity to M. tuberculosis DosR regulon-encoded antigens since responsiveness has been observed in non-M. tuberculosis-exposed but purified protein derivative-responsive individuals. M. tuberculosis DosR regulon-encoded antigen-specific T-cell responses were studied in peripheral blood mononuclear cells (PBMCs) of NTM-infected/exposed individuals. BLASTP was used to determine the presence of M. tuberculosis DosR regulon-encoded protein orthologs among environmental mycobacteria and nonmycobacteria. Significant gamma interferon production was observed in PBMCs from NTM-infected/exposed individuals in response to M. tuberculosis DosR regulon-encoded antigens. DosR regulon-encoded protein orthologs were prominently present in tuberculous and environmental mycobacteria and surprisingly also in nonmycobacteria. The ubiquitous presence of the highly conserved DosR master regulator protein Rv3133c suggests that this is a general adaptive bacterial response regulator. We report a first series of M. tuberculosis antigens to which cross-reactive immunity is induced by NTM infection/exposure. The high conservation of M. tuberculosis DosR regulon-encoded antigens most likely enables them to induce cross-reactive T-cell responses. PMID:19737909

A Bayesian Change point model for differential gene expression patterns of the DosR regulon of Mycobacterium tuberculosis  

PubMed Central

Background Low oxygen availability has been shown previously to stimulate M. tuberculosis to establish non-replicative persistence in vitro. The two component sensor/regulator dosRS is a major mediator in the transcriptional response of M. tuberculosis to hypoxia and controls a regulon of approximately 50 genes that are induced under this condition. The aim of this study was to determine whether the induction of the entire DosR regulon is triggered as a synchronous event or if induction can unfold as a cascade of events as the differential expression of subsets of genes is stimulated by different oxygen availabilities. Results A novel aspect of our work is the use of chemostat cultures of M. tuberculosis which allowed us to control environmental conditions very tightly. We exposed M. tuberculosis to a sudden drop in oxygen availability in chemostat culture and studied the transcriptional response of the organism during the transition from a high oxygen level (10% dissolved oxygen tension or DOT) to a low oxygen level (0.2% DOT) using DNA microarrays. We developed a Bayesian change point analysis method that enabled us to detect subtle shifts in the timing of gene induction. It results in probabilities of a change in gene expression at certain time points. A computational analysis of potential binding sites upstream of the DosR-controlled genes shows how the transcriptional responses of these genes are influenced by the affinity of these binding sites to DosR. Our study also indicates that a subgroup of DosR-controlled genes is regulated indirectly. Conclusion The majority of the dosR-dependent genes were up-regulated at 0.2% DOT, which confirms previous findings that these genes are triggered by hypoxic environments. However, our change point analysis also highlights genes which were up-regulated earlier at levels of about 8% DOT indicating that they respond to small fluctuations in oxygen availability. Our analysis shows that there are pairs of divergent genes where one gene in the pair is up-regulated before the other, presumably for a flexible response to a constantly changing environment in the host.

A comparative resonance Raman analysis of heme-binding PAS domains: heme iron coordination structures of the BjFixL, AxPDEA1, EcDos, and MtDos proteins.  

PubMed

The heme-PAS is a specialized domain with which a broad class of signal-transducing heme proteins detect physiological heme ligands. Such domains exhibit a wide range of ligand binding parameters, yet they are all expected to feature an alpha-beta heme binding fold and a predominantly hydrophobic heme distal pocket without a distal histidine. We have compared, for the first time, the resonance Raman spectra of several heme-PASs: the heme-binding domains of Bradyrhizobium japonicum FixL, Escherichia coli Dos, Acetobacter xylinum PDEA1, and Methanobacterium thermoautotrophicum Dos. In all cases, the nu(Fe)-(CO) and nu(C-O) values of the carbonmonoxy forms were consistent with coordination of the heme iron to histidine on the proximal side and binding of the CO without electrostatic interaction with the heme distal pocket. EcDos was unusual in having predominantly hexacoordinate heme iron in the deoxy and met forms. Despite an evident lack of CO interaction with the EcDos heme pocket, relatively low Fe-O(2) (562 cm(-1)) and N-O (1576 cm(-1)) stretching frequencies indicated that strong polar interactions with that heme distal pocket are possible for highly bent ligands such as O(2) or NO. None of the newly studied NO adducts exhibited evidence of the Fe-His rupture and pentacoordination previously noted for Sinorhizobium meliloti FixL. A low Fe-His stretching frequency, formerly interpreted as a strained Fe-His bond, and the slow association of O(2) with S. meliloti FixL failed to correlate with the newly studied proteins having low association rate or low equilibrium association constants for binding of O(2). We conclude that although heme-PASs share some features, they represent distinct signal transduction mechanisms. PMID:11939776

Exact DOS in the T-Matrix approximation: Demonstration of a robust pseudogap in the 3D Attractive Hubbard Model  

NASA Astrophysics Data System (ADS)

We have analyzed the 3D attractive Hubbard model (AHM) in the non self-consistent T-matrix approximation. We present a technique that allows for us to determine, exactly, the single-particle density of states (DOS) at all temperatures above the superconducting temperature, in the T-matrix approximation. Since this approximation scheme should be accurate, for weak to intermediate coupling and at low electronic densities, these results should be representative of a 3D superconductor in which the pairing results from purely electronic interactions. The DOS that we find shows clear evidence of a pseudogap well above Tc whose energy does not change with temperature. These results are very similar to the large body of work that has been completed analyzing 2D models, and suggests that perhaps the low dimensionality of the CuO2 planes is not necessary to produce such a phenomenon.

Rare earth elements in Angra dos Reis and Lewis Cliff 86010, two meteorites with similar but distinct magma evolutions  

NASA Technical Reports Server (NTRS)

Data are presented on ion microprobe measurements of REE and selected trace element abundances in individual grains of merrillite, fassaite, olivine, kirschsteinite, and plagioclase of Lewis Cliff 86010 (LEW 86010) meteorite and in merrillite and fassaite grains of Angra dos Reis (ADOR). Results show a close relationship between the two meteorites and support a magmatic origin for LEW 86010. However, the measurements indicate that, despite numerous common characteristics, the two meteorites must have been produced in separate magmatic events involving similar but distinct processes and parent melts.

A Novel Nuclear-Localized CCCH-Type Zinc Finger Protein, OsDOS, Is Involved in Delaying Leaf Senescence in Rice1[W  

PubMed Central

Leaf senescence is a developmentally programmed degeneration process, which is fine tuned by a complex regulatory network for plant fitness. However, molecular regulation of leaf senescence is poorly understood, especially in rice (Oryza sativa), an important staple crop for more than half of the world population. Here, we report a novel nuclear-localized CCCH-type zinc finger protein, Oryza sativa delay of the onset of senescence (OsDOS), involved in delaying leaf senescence in rice. The expression of OsDOS was down-regulated during natural leaf senescence, panicle development, and pollination, although its transcripts were accumulated in various organs. RNAi knockdown of OsDOS caused an accelerated age-dependent leaf senescence, whereas its overexpression produced a marked delay of leaf senescence, suggesting that it acts as a negative regulator for leaf senescence. A genome-wide expression analysis further confirmed its negative regulation for leaf senescence and revealed that, in particular, the jasmonate (JA) pathway was found to be hyperactive in the OsDOS RNAi transgenic lines but impaired in the OsDOS overexpressing transgenic lines, indicating that this pathway is likely involved in the OsDOS-mediated delaying of leaf senescence. Furthermore, methyl JA treatments of both seeds and detached leaves from the RNAi and the overexpressing transgenic lines showed hyper- and hyporesponses, respectively, consistent with the negative regulation of the JA pathway by OsDOS. Together, these results indicate that OsDOS is a novel nuclear protein that delays leaf senescence likely, at least in part, by integrating developmental cues to the JA pathway. PMID:16778011

Effect of Meteorological Phenomena in Measures of Background Radiation X and Gamma Rays in So Jos dos Campos, SP, Brazil  

NASA Astrophysics Data System (ADS)

The objective of this work was to perform a study on the influence of meteorological phenomena on the background radiation X and gamma rays in So Jos dos Campos, SP, Brazil on the last three years. For this, we performed the monitoring of the integrated radiations and also of the main meteorological parameters (rainfall, relative humidity, temperature and pressure) daily without interruptions and time resolution of one minute. Measurements of X and gamma radiation in the range of energies from 30 keV to 10 MeV, were carried out using a scintillator crystal of sodium iodide activated with Tallium [NaI(Tl)] coupled to a photomultiplier, with energy resolution of 15%. Rainfall, atmospheric pressure, temperature, and relative humidity were recorded using sensors coupled to a five-channel specific data logger. By correlating the data from the measurements of intensity of X and gamma radiations with the meteorological parameters, it was found that atmospheric precipitation with or without electric discharges phenomenon that was affected more in the spectrum of background radiation profile. Some of the reasons why these changes occur in the background profile are due the presence of environmental radon gas that is drawn to the surface during the occurrences of local rainfall. During dry periods, the spectra of X and gamma radiations showed a daily cycle (24 hour). In relation to relative humidity, temperature and pressure, it was found that these parameters had negligible influence on the profile changes of the background radiation in So Jos dos Campos, SP, Brazil.

Supporting Security against SYN Flooding Attack in Distributed DoS Via Measuring IPFIX-Based Traffic  

NASA Astrophysics Data System (ADS)

Distributed denial-of-service attacks on public servers after 2000 have become a serious problem. In the distributed denial-of-service (DDoS) attacks often seen recently, multiple distributed nodes concurrently attack a single server. To assure that network services will not be interrupted, faster and more effective defense mechanisms is needed to protect against malicious traffic, especially SYN floods. One problem in detecting SYN flood traffic is that server nodes or firewalls cannot distinguish the SYN packets of normal TCP connections from those of a SYN flood attack. Our method, FDFIX, relies on the use of monitoring and measurement techniques to evaluate the impact of DoS attacks. It uses flow based measurements. Capturing flow information is very important for detecting DoS and also other kinds of attacks. Flow monitoring allows detecting suspicious traffics and in the next step can analyze attacking flows and the results can be used for defense methods. Our method provides required information for many mechanisms that use traffic measurement as their input.

Assessment of human health risk from organochlorine pesticide residues in Cidade dos Meninos, Duque de Caxias, Rio de Janeiro, Brazil.  

PubMed

This article presents the results of a heath risk assessment in Cidade dos Meninos, an area contaminated with organochlorine pesticide residues located in the county (municipality) of Duque de Caxias, Rio de Janeiro State, Brazil. The Agency for Toxic Substances and Disease Registry (ATSDR) risk assessment methodology was applied. The following organochlorine compounds exceeded the established limits and were considered target pollutants: HCH and its isomers (in eggs, milk, and soil); DDT and its metabolites; trichlorobenzenes; trichlorophenols; dioxins and furans (eggs and soil). For all the substances studied (with the exception of trichlorophenols), the estimated doses exceeded the minimum risk levels for chronically exposed children and adults. According to the ATSDR classification, the area was considered an "urgent public health hazard" because of its high and serious exposure to substances that are dangerous to human health.

Seismogenic sources and crustal structure near the seismological station of Angra dos Reis (ESAR), southeastern region of Brazil  

NASA Astrophysics Data System (ADS)

The seismological station of Angra dos Reis (ESAR) is operating since the end of year 2000 located near to the nuclear power plants of Angra dos Reis, in the southern portion of Rio de Janeiro state, southeastern Brazil. The main objective of ESAR is defining the level of seismic activity in the area where those plants are installed, using data from a broadband seismograph that operates in a 100 cps continuous format. Epicentral determination of local seismic events is done through the back azimuth calculated with the P wave amplitude in the three component seismograms, and epicentral distance induced from the S-P time difference. Crustal structure for relating the S-P time and epicentral distance was obtained through a seismic refraction experiment using controlled sources, complemented with a detailed study of crustal structure beneath ESAR using teleseimic data and the receiver function method processed in the time domain. Since the beginning of operation ESAR has detected many local and near regional seismic events with magnitude lower than mb 4.0, most of them below mb 2.0, and not included in the Brazilian Seismic Catalogue. Epicenters of those events are spread in both oceanic and continental areas, in some cases forming clusters of different size, some of them, especially those located in the continent could belong to explosions made in stone-quarry, whereas, clusters and isolated epicenters located in the oceanic area could belong to natural earthquakes. Two of these oceanic clusters, located in the continental platform, may belong to seismogenic sources that are active near ESAR, and need further study to define its nature.
