    Full Text Available Exam performance was compared for students who hand wrote questions designed to prepare them for daily lab activities in a senior level virology laboratory course versus those who answered questions created to mirror the written questions on-line.  No significant difference was noted in exam scores on any of the three midterms, written final exam, nor the practical exam.  Neither was there a significant difference in the quality of the laboratory reports turned in as evidenced by similar average scores over four years.  These results indicate that using online pre-labs to prepare students for the laboratory sessions leads to equivalent learning as answering handwritten pre-lab assignments.  Online pre-labs significantly reduced the amount of grading without reducing student learning, allowing a reduction in the number of teaching assistants required per section.

    Motivating students to learn is a constant challenge for faculty. Technology can play a significant role. One such solution is WebAssign — a web-based homework system that offers new teaching and learning opportunities for educators and their students. WebAssign delivers, collects, grades, and records customized homework assignments over the Internet. Students get immediate feedback with credit and instructors can implement "Just-in-Time" teaching. In this talk, I will describe how assignments can be generated with different numerical values for each question, giving each student a unique problem to solve. This feature encourages independent thinking with the benefit of collaborative learning. Example assignments taken from textbook questions and intellectually engaging Java applet simulations will be shown. Studies and first-hand experience on the educational impact of using WebAssign will also be discussed.

  13. An integer programming model for assigning students to elective courses

    Directory of Open Access Journals (Sweden)

    Ivo Beroš

    2015-10-01

    Full Text Available This paper deals with the problem of assigning students to elective courses according to their preferences. This process of assigning students to elective courses according to their preferences often places before academic institutions numerous obstacles, the most typical being a limited number of students who can be assigned to any particular class. Furthermore, due to financial or technical reasons, the maximum number of the elective courses is determined in advance, meaning that the institution decides which courses to conduct. Therefore, the expectation that all the students will be assigned to their first choice of courses is not realistic (perfect satisfaction. This paper presents an integer programming model that maximizes the total student satisfaction in line with a number of different constraints. The measure of student satisfaction is based on a student's order of preference according to the principle: the more a choice is met the higher the satisfaction. Following the basic model, several versions of the models are generated to cover possible real-life situations, while taking into consideration the manner student satisfaction is measured, as well as the preference of academic institution within set technical and financial constraints. The main contribution of the paper is introducing the concept of the minimal student satisfaction level that reduces the number of students dissatised with the courses to which they were assigned.

  17. A stepwise multi-assignment spreadsheet model to select student teams

    Directory of Open Access Journals (Sweden)

    Bilge Gokhan Celik

    2013-06-01

    Full Text Available Student projects play a big role in engineering and management education. Most projects require students to work in teams, which allow students to practice their technical knowledge, foster the development of personal leadership skills, and teach the value of team accomplishments. One of the challenges of administering team projects is to create the best team compositions that give all teams the equal chance of success while maximizing interaction between students. The instructor should strive to balance each team so the team capabilities are as even as possible. Instructors also should take into account the performance of each student throughout the semester, when recreating teams for upcoming assignments. This paper presents a stepwise optimization that continues throughout the semester as the teams evolve from one assignment to another. Results show that this method can expose students to approximately 50% of their classmates within four team assignments and reasonable team grade variance.

  19. Combining Concept Maps with Quantitative Data and Writing Assignments to Foster Student Engagement

    Science.gov (United States)

    Bank, C.; Eckert, T.

    2008-12-01

    Introductory geoscience is in a unique position to provide students with readily available data, problems that require careful analysis, and issues affecting their communities. Teaching introductory geoscience allows the instructors to package the developing of skills (quantitative numeracy, critical thinking, presenting) with the learning of new concepts. We have introduced in a large distribution course several assignments which combine concept maps with the analysis of quantitative data and short writing requirements. The aim of such assignments is to allow students to gain insight into scientific thinking, to challenge their pre-existing conceptions, and to achieve a deeper understanding of topics. It also provides us with the opportunity to experiment with novel assessment tools. In some cases, we have attempted to proof the effectiveness of such assessments. For example, a preliminary comparison of student performance on final exams indicates a correlation between marks gained on a concept map and those achieved on a short essay. This correlation implies that concept maps can be valid assessment tools. Other assignments, for example the creation of podcasts by small groups of students, provide for anecdotal evidence that students learn new concepts better because they need to reflect on them more carefully in order to present the assigned material.

  1. Improving Geoscience Learning and Increasing Student Engagement Using Online Interactive Writing Assignments with Calibrated Peer Review.

    Science.gov (United States)

    Harbor, Jon

    2014-05-01

    Peer review is a hallmark of the publication process for scientific research, yet it is rarely used as a pedagogical approach in university geoscience courses. Learning outcomes for university geoscience courses include content knowledge and critical thinking and analysis skills, and often include written communication of scientific issues or concepts. Because lecture and memorization is not the most effective learning approach for many students, instructors are increasingly exploring teaching approaches that involve active engagement. In this context, writing assignments that engage students in using content, constructing arguments, and critiquing other students' work are highly desirable. However, many of us struggle with extensive writing requirements in our courses because the workload associated with having the instructor provide detailed comments on writing is daunting, especially in large-enrollment courses, and organizing effective peer review by students is very challenging. Calibrated Peer Review (CPR) is a web-based program that involves students in writing and in reviewing each other's writing. It is designed to allow for more involved writing and feedback experiences with much less instructor time. Here we report on the results of a qualitative-methods analysis of narrative survey responses from students using CPR in an introductory geoscience class. In addition to an impact on the students' writing and their understanding of what goes in to effective writing, the results indicate that CPR acted as reinforcement for content learning, and an impetus for gaining a deeper understanding of content material. It allowed students to see how other students explained and analyzed content, and to check their understanding of a topic in relation to other students in the class. Not surprisingly, the instructor reported that students performed far better on exam questions that tested knowledge covered by CPR assignments.

  13. Investigating the Manifestation of Textual Themes in Argumentative English Assignments Written by Iraqi and Australian Postgraduate Students

    Directory of Open Access Journals (Sweden)

    Ali Jabbar Al BAKAA

    2014-11-01

    Full Text Available This study investigated the manifestation of Textual Themes in argumentative English assignments written by Iraqi and Australian postgraduate students. Textual structure is a core component of argumentation in academic writing. How the themes in a text are organized as a message component constructs voice and authority. An important question is how novice writers and in particular international students are able to handle these textual devices when they write their English academic assignments. To this end, four academic assignments were selected and analysed to uncover the similarities and differences in textual features, and how students of different cultures stamp their authorial voice on the text through the element of theme and rheme in their academic arguments. The data were analysed based on Halliday’s (2004 model of thematic organization. The findings showed that the failure to use theme appropriately in constructing a voice and authority in academic writing may have disadvantaged the non-native writers. The paper argues that this has occurred because critical thinking requires a clear self-voice in forming an academic argument. This has not been explicitly emphasized in the writers’ Iraqi curriculum for writing. In contrast, these elements are more explicitly emphasized in the Australian writing curriculum.Keywords: English academic assignments; Iraqi non-native writers; Australian native writers; textual structure; voice and authority; thematic organization; critical thinking

  14. The Impact of Color-Coding Freshmen Integrated-Science Assignments on Student Achievement

    Science.gov (United States)

    Sturdivant Allen, Anita Kay

    Students in Grade 9 exhibit high rates of grade retention and absenteeism. Educators have used different strategies that will increase the achievement of those students. The purpose of this study was to determine whether a relationship existed between student achievement and the strategy to use colored paper for Grade 9 science assignments and tests. Itten's color theory provided the theoretical framework. Itten was one of the first researchers to explore the notion that the human eye can detect wavelengths as colors and that those colors can engage and create order in the human brain. A sample of students assigned to 4 classroom teachers at one high school who volunteered to take part in the study for 18 weeks were used in this quantitative study. Teachers administered student assessments on blue, green, yellow, and white paper. Each class was assigned 1 of the 4 colors for 4.5 weeks. The classes were then assigned a different color for the same length of time until each class had exposure to all 4 colors. Physical science exams given to students in the same grade or subject were used as the dependent variable. An ANOVA indicated that the groups using blue paper scored the highest on the physical science exams; students who used white paper earned the lowest scores. When comparing all 3 groups using colored paper (all three colored paper groups combined into one group) to the white paper groups, t-test results indicated that students using any colored paper scored higher than students using white paper. Further research on the impact of colored paper on student academic performance is necessary. Implications for positive social change indicate that new knowledge about instructional tools that impact student achievement deserves more attention.

  15. "Why bother so incredibly much?": student perspectives on PISA science assignments

    Science.gov (United States)

    Serder, Margareta; Jakobsson, Anders

    2015-09-01

    Large-scale assessment, such as the Programme for International Assessment (PISA), plays an increasingly important role in current educational practice and politics. However, many scholars have questioned the validity and reliability of the tests and the extent to which they actually constitute trustworthy representations of students' knowledge. In the light of such critical voices the present article adopts a sociocultural perspective of human knowledge and action in order to explore the encounters between students and the science test assignments with which their knowledge is tested. Of particular interest in this study are the described "real-life situations" presented as the relevant background in which scientific literacy is assessed in PISA. According to the sociocultural theoretical onset the methodology used to approach the students' meaning making of the image of science as portrayed in the test were collaborative situations in which students work in small groups with units of PISA assignments, enabling a study of student-assignment encounters in action. The data we worked with consists of video-recordings from 71 Swedish 15-year-old students working with three released units from the PISA science test. According to our analysis, the "real-life situations" described in the test emerge as problematic in the students' meaning-making. This is demonstrated for instance by the students' positioning themselves as being different from and opposed to the fictional pictured students who appear in the backstories of the test. This article provides examples of how the scientific and academic language used by the fictional students in the assignments mediates distance and resistance among the students. The fictional students' use of strict scientific language and methods in day-to-day life situations leads them to be perceived as "little scientists" and as elite stereotypes of the scientific culture. We conclude that, by using assignments of this type, measurements of students' knowledge in science run the risk of becoming a measurement of cultural consistency regarding how well students will overcome the hurdles of scientific cultures. We mean that all though understanding the scientific culture is an important goal for science education, there is a problem that the assessment organizations communicate the results as representations of students' knowledge in science. This study adheres to research that advises caution in not over-interpreting the PISA results and stresses that understanding students' "knowledge" about science is much more complex than what is communicated by the international assessment organizations.

  16. Using Cloud collaboration for writing assignments by students with disabilities: a case study using action research

    Directory of Open Access Journals (Sweden)

    Kjrsten Keane

    2014-02-01

    Full Text Available Though separated by geographical distance, a student with disabilities, his advisor, and his writing coach consorted in the Cloud using Google applications to achieve a writing goal. Our scenario demonstrates how emerging technologies can bridge transactional distance and “virtually” supplant face-to-face conferencing around a college writing assignment. Individual levels of technical acumen with digital technology evolved to bridge the psychological and communication space between the student and his instructors. As a result, the telecollaborators developed an efficient coaching process adaptable for all students who need assistance in revising college writing assignments at a distance. Action research frames our discussion of the Cloud collaboration and provides a scaffold for student autonomy. The advantages as well and disadvantages of Cloud collaboration are outlined with reference to the National Institute of Standards of Technology definition of Cloud Computing and the Seven Principles of Universal Course Design.http://dx.doi.org/10.5944/openpraxis.6.1.79

    2012-05-01

    Full Text Available Assign students to create a website, video, or podcast, and they can become more engaged with content and more capable in communication, teamwork, critical thinking, and ethics. That is the promise. Still needed are documentation and dissemination of effective teaching approaches and suitable platforms to handle inevitable copyright issues. We characterise these needs here through a case study of one web publishing assignment in science that has run since 2003, brief descriptions of other new media assignments being undertaken by science academics in Australia, and the attractions and concerns thattheir colleagues voice. The discussion points to a critical question, the level of commitment of university academics to preparing their graduates to handle the complexity of relationships with stakeholders that the web can readily present. Are lecturers ready to take on the preparation of students to employ digital media to relate to audiences outside the university?

    2011-01-01

    The "Visions of the Universe" exhibit was created by the American Library Association, Space Telescope Science Institute and the Smithsonian Astrophysical Observatory to celebrate the International Year of Astronomy. The exhibit consists of 12 posters. Smaller versions of the posters can be downloaded from http://amazing-space.stsci.edu/visions/ for use at institutions that were not part of the exhibit display. We arranged to display these smaller versions at Joliet Junior College. To encourage ASTR 101 and Life in the Universe students to expand their interest in astronomy via these posters, in Spring 2010 we designed a short essay assignment that counted as one homework. This assignment involved exploring a poster topic further via the internet. In addition to learning about the topic, students were asked to critique the webpage they chose as their reference, and to recommend whether or not their chosen webpage would be a suitable resource for non-science majors. We will provide details of the assignment, and report on which exhibit topics were most popular, which websites students referred to and which they recommended for introductory astronomy courses.

  2. Evolution of Various Library Instruction Strategies: Using Student Feedback to Create and Enhance Online Active Learning Assignments

    2013-06-01

    Full Text Available This case study traces the evolution of library assignments for biological science students from paper-based workbooks in a blended (hands-on workshop to blended learning workshops using online assignments to online active learning modules which are stand-alone without any face-to-face instruction. As the assignments evolved to adapt to online learning supporting materials in the form of PDFs (portable document format, screen captures and screencasting were embedded into the questions as teaching moments to replace face-to-face instruction. Many aspects of the evolution of the assignment were based on student feedback from evaluations, input from senior lab demonstrators and teaching assistants, and statistical analysis of the students’ performance on the assignment. Advantages and disadvantages of paper-based and online assignments are discussed. An important factor for successful online learning may be the ability to get assistance.

Overall, results indicated that students with above average (n = 16), average, (n = 17) and below average (n = 14) chemistry potential whom were given teacher assigned and graded chemistry homework compared to students with above average (n = 17), average (n = 15), and below average (n = 19) chemistry potential whom were given teacher assigned but not graded chemistry homework had statistically significantly higher independent t test matter homework scores while atoms, naming, and reactions homework scores were generally in the direction of higher but not significant scores for students given graded homework regardless of their chemistry potential. Furthermore, students of above average and below average chemistry potential who were given assigned and graded chemistry homework performed statistically significantly better on the 11th-grade district prepared chemistry final and the district prepared physical science strand Essential Learner Outcome assessment t test results compared to students with the same chemistry potential given assigned but not graded chemistry homework, suggesting that the graded chemistry condition may have contributed to improved long term learning and retention of chemistry knowledge. Finally, the coefficient of determination (r2 = .95) measure of strength of relationship between not completing, not graded chemistry homework and a corresponding drop in chemistry assessment scores for all students was 95% and the coefficient of determination (r2 = .82) measure of strength of relationship between not completing, graded chemistry homework and a corresponding drop in chemistry assessment scores for all students was 82%. While not implying causality the study findings suggest that students who complete more homework, not graded or graded, have a higher probability of improving their chemistry assessment scores regardless of their chemistry potential.

    2007-12-01

    By using the book "Physics for Scientists and Engineers" by Raymond A. Serway as a guide, CD problem sets for teaching a calculus-based physics course were developed, programmed, and evaluated for homework assignments during the 2003-2004 academic year at Utah State University. These CD sets were used to replace the traditionally handwritten and submitted homework sets. They included a research-based format that guided the students through problem-solving techniques using responseactivated helps and suggestions. The CD contents were designed to help the student improve his/her physics problem-solving skills. The analyzed score results showed a direct correlation between the scores obtained on the homework and the students' time spent per problem, as well as the number of helps used per problem.

    Full Text Available Introduction: In a four-year undergraduate level , the nursing students have to get prepared in the patients education, designing care plans, applying nursing processes and exercise the clinical decisions, in addition to learning practical skills. Therefore, multiple clinical teaching strategies in nursing must be applied. In this study the sheets for the mentioned fields were designed and used. Methods: In this action research in Tabriz University of Medical Sciences, 64 nursing senior students and related instructors participated. Clinical written assignment included the patient’s health condition sheet, tables showing the used medicines and the precautions, the clinical and paraclinical tests and the results, identifying the patient problems, designing and implementing care plan and writing nursing reports with SOAPIE method. The instructors’ viewpoints were achieved through the group discussions and their notes taken. The perceived competency of the students was obtained through a questionnaire. The qualitative data was analyzed by the content analysis and quantitative using SPSS. Results: Both the students and the instructors agreed with the clinical written assignment. The desired care competency of the students before and after assignment was statistically significant (p<0.05. According to the instructors, intervention was useful for the senior students who have passed the courses needed for completing and using the different parts of these forms. Conclusion: Since a need is always felt in the trends of the nursing clinical teaching, the researchers recommend the clinical written assignment and their application along with other strategies for senior nursing students in clinical teaching.

  18. A study of a science-based peer reading assignment and its effects on first grade student understanding and use of describing words in science

    Science.gov (United States)

    Pearson, Meghan Jeanne

    The first grade curriculum for science in Colorado requires students be able to use describing words to depict and compare objects and people; however, first graders struggle with using specific enough language to create strong descriptions. With science education research encouraging teachers to use alternative teaching methods to approach these challenging topics, it is important to provide teachers with resources appropriate to their students. One such alternative learning method is a reading partner. Reading partners have been shown to increase vocabulary, boost school performance, and improve self-esteem in children. This study analyzed the effectiveness of using a science-based peer reading assignment about describing words on increasing a first grader's understanding of the topic. The book required the class to work together to help the characters describe different images and characters in the book with the intent that students were engaged during the reading. In pre-interview and post-interview, students described pictures, and their responses were analyzed for quality of the describing words provided and the number of strong (specific and not opinion) describing words provided. In the post-interview, students had an overall increase in the number of strong describing words provided. The quantitative data was analyzed by comparing strong describing words used pre-reading and post-reading, and the effect size was very large. The results indicate reading the book explaining describing words that asked for student participation did increase students understanding and use of describing words.

  1. Why the Rhetoric of CS Programming Assignments Matters

    Science.gov (United States)

    Wolfe, Joanna

    2004-06-01

    Despite the multiple potential benefits of asking students working on programming tasks to consider human factors, most programming assignments narrowly focus on technical details and requirements. Female students in particular may be attracted to assignments that emphasize human as well as technical factors. To assess how students respond to changes in the rhetorical presentation of programming instructions, 81 students completed questionnaires evaluating different assignment instructions. Students generally perceived assignments emphasizing real-world contexts and users as more motivating and enjoyable to program than those that did not emphasize human factors. Moreover, when asked what makes a "good" programming assignment, over half of the students volunteered that they looked for assignments stressing a real-world purpose, use or application.

  9. Grouped to Achieve: Are There Benefits to Assigning Students to Heterogeneous Cooperative Learning Groups Based on Pre-Test Scores?

    Science.gov (United States)

    Werth, Arman Karl

    Cooperative learning has been one of the most widely used instructional practices around the world since the early 1980's. Small learning groups have been in existence since the beginning of the human race. These groups have grown in their variance and complexity overtime. Classrooms are getting more diverse every year and instructors need a way to take advantage of this diversity to improve learning. The purpose of this study was to see if heterogeneous cooperative learning groups based on student achievement can be used as a differentiated instructional strategy to increase students' ability to demonstrate knowledge of science concepts and ability to do engineering design. This study includes two different groups made up of two different middle school science classrooms of 25-30 students. These students were given an engineering design problem to solve within cooperative learning groups. One class was put into heterogeneous cooperative learning groups based on student's pre-test scores. The other class was grouped based on random assignment. The study measured the difference between each class's pre-post gains, student's responses to a group interaction form and interview questions addressing their perceptions of the makeup of their groups. The findings of the study were that there was no significant difference between learning gains for the treatment and comparison groups. There was a significant difference between the treatment and comparison groups in student perceptions of their group's ability to stay on task and manage their time efficiently. Both the comparison and treatment groups had a positive perception of the composition of their cooperative learning groups.

    2016-01-01

    Research shows that expert-like approaches to problem-solving can be promoted by encouraging students to explicate their thought processes and follow a prescribed problem-solving strategy. Since grading communicates instructors' expectations, teaching assistants' grading decisions play a crucial role in forming students' approaches to problem-solving in physics. We investigated the grading practices and considerations of 43 graduate teaching assistants (TAs). The TAs were asked to grade a set of specially designed student solutions and explain their grading decisions. We found that in a quiz context, a majority of TAs noticed but did not grade on solution features which promote expert-like approaches to problem-solving. In addition, TAs graded differently in quiz and homework contexts, partly because of how they considered time limitations in a quiz. Our findings can inform professional development programs for TAs.

Students were given a PLUS model booklet, were required to select a topic in the area of sound technology, and were expected to do brainstorming and concept mapping and to produce a 600?word essay. After the assignment was completed, three methods of data collection were employed to determine students’ and teachers’ views: 1 post?assignment questionnaire 2 group interviews with students and teachers 3semi?structured interview with the school librarian.Main results – Responses indicated that students were “mostly” satisfied with the use of the PLUS model, although there were 18 students who did not respond to questions regarding the use of the booklet. It was also clear from the questionnaire that the majority of the students did not feel confident in their abilities to produce a satisfactory assignment prior to beginning the research; however, 48% of the students indicated that the PLUS booklet made them more confident. A comparable number of students said the booklet had no effect on their confidence and one student said it made them less confident. Students responded very positively about the use of individual brainstorming and concept mapping as a way to organize and focus on their topic. (There was a split between those who felt a written concept map was useful and those who felt a mental concept map was just as helpful. The majority of students felt that group brainstorming was helpful, while a few indicated the behavior of other students during group brainstorming was a hindrance. Questions about preliminary reading were not open?ended but were multiple choice. There was no response to indicate whether the preliminary reading was helpful or not, but rather how it was helpful. Most students indicated it had helped to identify the right keywords for further research and it helped them in finding the right resources. Students were questioned on the format of their note?taking. Sixty?five per cent preferred to hand write their notes in a notebook; fifteen per cent preferred to take notes electronically in some type of word processing program; twelve per cent preferred to cut and paste into a word processor; and eight per cent preferred “other methods.” Note?taking styles ranged from bulleted lists to spider diagrams, to using headings with categorized notes. When asked to indicate the percentage of information derived from Web sites versus information from books and journals, responses showed that over 65.5 % of the information came from web sites while only 35.5 % came from print material. When asked why, students responded that Websites were easier to read,

    2015-01-01

    Nurses work with diverse populations, but the nursing literature lacks research, theoretical frameworks, or practice guidelines regarding lesbian, gay, bisexual, and transgender (LGBT) health. Through diverse teaching strategies, students explored issues related to LGBT patients, families, and nurses using a cultural humility lens. Diverse teaching strategies included readings, a 2-hour presentation on LGBT health issues, and an assignment to conduct a scripted interview with two nurse key informants, based on the Health Care Equality Index (HEI). Students completed an online LGBT awareness preinterview survey, completed interviews, and completed a postinterview survey. Students showed a significant increase in knowledge about sexual orientation and gender identity and research and interview methods from pretest to posttest. The diverse teaching strategies involved in this assignment can enhance student knowledge, attitudes, and skills related to LGBT health care needs and increase appreciation of nursing research.

Through an empirical study of supervision and feedback on student assignments at the university across face-to-face and online settings we show firstly, that the traditional dichotomy between face-to- face and online supervision proves unhelpful when trying to understand how online supervision and feedback is a pedagogical phenomenon in its own right, and irreducible to the face-to-face context. Secondly we show that not enough attention has been given to the way different digital tools and platforms influence the supervisory dialogue in the specific supervision context. We conclude by terming this challenge in online supervision aform of ‘torn pedagogy’; that online tools and platforms destabilise and ‘tear’ traditional understandings of supervision pedagogy ‘apart’. Also, we conclude that on the backdrop of a torn pedagogy we forge a new concept of “format supervision” that enables supervisors to understand and reflect their supervision practice, not as caught in the physical-virtual divide, but as a choice between face-to-face and online formats that each conditions the supervisory dialogue in their own particular ways and with their own pedagogical implications.

    This purpose of this study was to evaluate the effects of web-based homework assignments on student (a) achievement, (b) homework completion rates, (c) reflectivity and critical-thinking skills, (d) computer usage skills, and (e) attitudes toward science classes and homework. The specific data sources that were collected and analyzed during the investigation included (a) pretests, posttests, and post-posttests, (b) teacher-created classroom quizzes, (c) a student attitude survey, (d) a computer skills survey, (e) pre- and post-experimental focus group interviews, and (f) a survey of encountered computer problems. In addition to these data sources, all student assignments were coded and analyzed for reflective content and critical-thinking skills usage. Finally, student homework completion rates were monitored. The results indicated the following: (1) The online assignments were at least as effective as traditional assignments in terms of student achievement. (2) The online assignments required less time to complete than did traditional homework assignments. (3) The online assignments were rated highly by members of the experimental group. (4) The online assignments had no significant impact on the homework completion rates of students. (5) The online assignments had no significant impact on student computer skills. (6) The online assignments helped to facilitate the improvement of student attitudes toward the use of technology in science classes. (7) The online assignments facilitated increased student reflectivity. (8) The online assignments helped to improve the attitudes of some of the experimental students toward science and science classes. Since very little research exists concerning the effects of online instruction on high school students, future research should expand the time frame, sample size, and sample composition of this study in order to ensure that the results obtained can be applied to the general student population.

    2012-03-01

    Full Text Available The First Year Experience Programme (FYE at the University of Auckland’s Faculty of Arts is in its second year of operation. After a year of focusing on pastoral care, things were running smoothly. We were able to implement a special project in the second year focused on two significant areas of academic support which are increasingly underused by first year students: student willingness to access to university wide teaching support services; and low usage of tutor office hours when students are preparing for a major assignment. The solution was the creation of Targeted Learning Sessions which are designed to attract students in selected large year one courses to engage with an easy-access option of discipline-specific academic support. This article sets up factors influencing the conception of the project and then provides a systematic breakdown of the way in which course convenors, the First Year Experience programme, library and student learning personnel combined forces to offer students a new way of seeking academic support that was not behind a closed office door.

    Hale, F A; McConnochie, K M; Chapman, R J; Whiting, R D

    1979-05-01

    The impact of a required preceptorship program was measured by comparing the perceptions of senior medical students who would have elected the preceptorship rotation had it not been required (the elective group) and those who participated only to fulfill the requirement (the required group). The main difference between the two groups before the preceptorship was the elective group's career preference for family medicine and the required group's preference for an internal medicine subspecialty. The preceptorship had no impact for either group on inclinations toward other specialties, preferred practice setting, or assessment of practice location determinants. Both groups, however, perceived an increase in knowledge of primary care practice and confidence in relevant clinical skills following the preceptorship. These results are used to support the value of a required preceptorship program. PMID:439125

  10. Formal operational reasoning modes: Predictors of critical thinking abilities and grades assigned by teachers in science and mathematics for students in grades nine through twelve

    Science.gov (United States)

    Bitner, Betty L.

    To test the hypothesis that formal operational reasoning modes are predictors of critical thinking abilities and grades assigned by teachers in science and mathematics, in September 1986 the Group Assessment of Logical Thinking (GALT) and in December 1986 the Watson-Glaser Critical Thinking Appraisal (WGCTA) were administered to 101 rural students in Grades 9 through 12. The grades assigned by teachers were collected in May 1987. Construct and criterion-related validities and internal-consistency reliability using Cronbach's alpha method were established on the GALT. On the WGCTA, content and construct validities and internal consistency reliability using the split-half procedure, coefficient of stability, and coefficient of equivalence were established. The five formal operational reasoning modes in the GALT were found to be significant predictors of critical thinking abilities and grades assigned by teachers in science and mathematics. The variance in the five critical thinking abilities attributable to the five formal operational reasoning modes ranged between 28% and 70%. The five formal operational reasoning modes explained 29% of the variance in mathematics achievement and 62% of the variance in science achievement.

    Torremorell, Maria Carme Boqué; de Nicolás, Montserrat Alguacil; Valls, Mercè Pañellas

    Teacher training at the Blanquerna Faculty of Psychology and Educational and Sports Sciences (FPCEE), in Barcelona, has a long pedagogical tradition based on teaching innovation. Its educational style is characterised by methods focused on the students' involvement and on close collaboration with teaching practice centres. Within a core subject in the Teacher Training diploma course, students were asked to assess different methodological proposals aimed at promoting the development of their personal, social, and professional competences. In the assessment surveys, from a sample of 145 students, scores for variables very satisfactory or satisfactory ranged from 95.8 % to 83.4 % for the entire set of methodological actions under analysis. Data obtained in this first research phase were very useful to design basic training modules for the new Teacher Training Degree. In the second phase (in process), active teachers are asked for their perception on the orientation of the practicum, its connection with the end-of-course assignment, and the in-service student's incidence on innovation processes at school.

  17. Do medical students require education on issues related to plagiarism?

    Science.gov (United States)

    Varghese, Joe; Jacob, Molly

    2015-01-01

    In the course of our professional experience, we have seen that many medical students plagiarise. We hypothesised that they do so out of ignorance and that they require formal education on the subject. With this objective in mind, we conducted a teaching session on issues related to plagiarism. As a part of this, we administered a quiz to assess their baseline knowledge on plagiarism and a questionnaire to determine their attitudes towards it. We followed this up with an interactive teaching session, in which we discussed various aspects of plagiarism. We subjected the data obtained from the quiz and questionnaire to bivariate and multivariate analysis. A total of 423 medical students participated in the study. Their average score for the quiz was 4.96±1.67 (out of 10). Age, gender and years in medical school were not significantly associated with knowledge regarding plagiarism. The knowledge scores were negatively correlated with permissive attitudes towards plagiarism and positively correlated with attitudes critical of the practice. Men had significantly higher scores on permissive attitudes compared to women . In conclusion, we found that the medical students' knowledge regarding plagiarism was limited. Those with low knowledge scores tended to have permissive attitudes towards plagiarism and were less critical of the practice. We recommend the inclusion of formal instruction on this subject in the medical curriculum, so that this form of academic misconduct can be tackled. PMID:25671582

  18. Personnel dose assignment practices

    International Nuclear Information System (INIS)

    Implementation of DOE N 5480.6 Radiological Control Manual Article 511(3) requirements, to minimize the assignment of personnel dosimeters, should be done only under a broader context ensuring that capabilities are in place to monitor and record personnel exposure both for compliance and for potential litigation. As noted in NCRP Report No. 114, personnel dosimetry programs are conducted to meet four major objectives: radiation safety program control and evaluation; regulatory compliance; epidemiological research; and litigation. A change to Article 511(3) is proposed that would require that minimizing the assignment of personnel dosimeters take place only following full evaluation of overall capabilities (e.g., access control, area dosimetry, etc.) to meet the NCRP objectives

  1. Interprofessional education: Lessons learned from conducting an electronic health record assignment.

    2015-11-01

    Ineffective collaboration and communication contribute to fragmented patient care and potentially increase adverse events, clinical errors, and poor patient outcomes. Improving collaboration and communication is essential; however, interprofessional education (IPE) supporting this cause is not a common practice. Most often healthcare profession students are educated in profession-centered silos limiting opportunities to develop effective communication and collaboration practices. Students from nursing, health informatics, and radiologic technology collaboratively populated an academic electronic health record (AEHR) using fictitious case study data. The assignment was designed to address the Quality and Safety Education for Nurses and IPE Collaborative competencies. The objective was to evaluate students' informatics competency, teamwork behaviors, and communication skills while exploring the different roles and responsibilities for collaborative practice after participating in an interprofessional case study assignment. Students gained experience using the AEHR for data entry, analysis, and application increasing their informatics competency. The assignment required students to communicate and actively collaborate as an interprofessional team to achieve the assignment objectives. Clinical errors often occur during care transitions, so simulating this process in the assignment was essential. Nursing and radiologic technology students had to analyze patient data and develop a hand-off communication template supporting patient safety and optimizing outcomes. The assignment required students to work as an interprofessional team and demonstrate how communication and collaboration is an essential component to quality and safe patient care. PMID:25955409

  1. A descriptive study of the middle school science teacher behavior for required student participation in science fair competitions

    Science.gov (United States)

    Fisanick, Laura M.

    This descriptive study explores three aspects of teacher behavior related to student participation in science fair competitions: teacher attitudes, teacher preference for different student-learning modes, and teacher motives for required student participation. Teacher motives for required student participation may stem from curriculum and standardized test requirements, school administrators' expectations, teacher preference for a competitive student-learning mode, and teacher attitudes towards science fair competitions. Survey data collected for this study included teacher attitudes about science fair competitions, teacher preference for different student-learning modes, and demographic data about middle school teachers who sponsor students in PJAS science fair competitions. The theoretical framework in this study is the theory of planned behavior proposed by Ajzen. The results from the analysis of data in this study showed that the majority of the teachers in this sample held positive attitudes towards science fair competitions and required their students to conduct science fair projects but did not require their students to participate in science fair competitions. The middle school science teachers in the sample would involve their students in PJAS competitions even if their districts did not require them to participate. The teachers in this study preferred the cooperative and individualistic student-learning modes. Teacher gender did not influence a preference for a particular student-learning mode. Using the theoretical framework from this study revealed teachers who required their students to participate in science fair competitions also required their students to conduct science fair projects.

    Evidence-based medicine (EBM) is delivered through a didactic, blended learning, and mixed models. Students are supposed to construct an answerable question in PICO (patient, intervention, comparison, and outcome) framework, acquire evidence through search of literature, appraise evidence, apply it to the clinical case scenario, and assess the evidence in relation to clinical context. Yet these teaching models have limitations especially those related to group work, for example, handling uncooperative students, students who fail to contribute, students who domineer, students who have personal conflict, their impact upon progress of their groups, and inconsistent individual acquisition of required skills. At Pediatrics Department, Faculty of Medicine, Cairo University, we designed a novel undergraduate pediatric EBM assignment online system to overcome shortcomings of previous didactic method and aimed to assess its effectiveness by prospective follow-up during academic years 2012 to 2013 and 2013 to 2014. The novel web-based online interactive system was tailored to provide sequential single and group assignments for each student. Single assignment addressed a specific case scenario question, while group assignment was teamwork that addressed different questions of same case scenario. Assignment comprised scholar content and skills. We objectively analyzed students' performance by criterion-based assessment and subjectively by anonymous student questionnaire. A total of 2879 were enrolled in 5th year Pediatrics Course consecutively, of them 2779 (96.5%) logged in and 2554 (88.7%) submitted their work. They were randomly assigned to 292 groups. A total of 2277 (89.15%) achieved ? 80% of total mark (4/5), of them 717 (28.1%) achieved a full mark. A total of 2178 (85.27%) and 2359 (92.36%) made evidence-based conclusions and recommendations in single and group assignment, respectively (P < 0.001). A total of 1102 (43.1%) answered student questionnaire, of them 898 (81.48%) found e-educational experience satisfactory, 175 (15.88%) disagreed, and 29 (2.6%) could not decide. A total of 964 (87.47%) found single assignment educational, 913 (82.84%) found group assignment educational, and 794 (72.3%) enjoyed it. Web-based online interactive undergraduate EBM assignment was found effective in teaching medical students and assured individual student acquisition of concepts and skills of pediatric EMB. It was effective in mass education, data collection, and storage essential for system and student assessment. PMID:26200621

  11. Mars - robust automatic backbone assignment of proteins

    International Nuclear Information System (INIS)

    MARS a program for robust automatic backbone assignment of 13C/15N labeled proteins is presented. MARS does not require tight thresholds for establishing sequential connectivity or detailed adjustment of these thresholds and it can work with a wide variety of NMR experiments. Using only 13C?/13C? connectivity information, MARS allows automatic, error-free assignment of 96% of the 370-residue maltose-binding protein. MARS can successfully be used when data are missing for a substantial portion of residues or for proteins with very high chemical shift degeneracy such as partially or fully unfolded proteins. Other sources of information, such as residue specific information or known assignments from a homologues protein, can be included into the assignment process. MARS exports its result in SPARKY format. This allows visual validation and integration of automated and manual assignment

    2014-01-01

    Full Text Available Functional magnetic resonance imaging was used to identify the brain-based mechanisms of uncertainty and certainty associated with answers to multiple-choice questions involving common misconceptions about electric circuits. Twenty-two (22 scientifically novice participants (humanities and arts college students were asked, in an fMRI study, whether or not they thought the light bulbs in images presenting electric circuits were lighted up correctly, and if they were certain or uncertain of their answers. When participants reported that they were unsure of their responses, analyses revealed significant activations in brain areas typically involved in uncertainty (anterior cingulate cortex, anterior insula cortex, and superior/dorsomedial frontal cortex and in the left middle/superior temporal lobe. Certainty was associated with large bilateral activations in the occipital and parietal regions usually involved in visuospatial processing. Correct-and-certain answers were associated with activations that suggest a stronger mobilization of visual attention resources when compared to incorrect-and-certain answers. These findings provide insights into brain-based mechanisms of uncertainty that are activated when common misconceptions, identified as such by science education research literature, interfere in decision making in a school-like task. We also discuss the implications of these results from an educational perspective.

  3. Inferential backbone assignment for sparse data

    International Nuclear Information System (INIS)

    This paper develops an approach to protein backbone NMR assignment that effectively assigns large proteins while using limited sets of triple-resonance experiments. Our approach handles proteins with large fractions of missing data and many ambiguous pairs of pseudoresidues, and provides a statistical assessment of confidence in global and position-specific assignments. The approach is tested on an extensive set of experimental and synthetic data of up to 723 residues, with match tolerances of up to 0.5 ppm for C? and C? resonance types. The tests show that the approach is particularly helpful when data contain experimental noise and require large match tolerances. The keys to the approach are an empirical Bayesian probability model that rigorously accounts for uncertainty in the data at all stages in the analysis, and a hybrid stochastic tree-based search algorithm that effectively explores the large space of possible assignments

  4. Doing homework: perspectives of elementary and junior high school students.

    Bryan, T; Nelson, C

    1994-10-01

    A survey of homework experiences was administered to 1,527 elementary and junior high students in regular (n = 1,242), resource (n = 234), and self-contained special education (n = 51) classrooms. The results found significant main effects for Group, Grade, and Group by Grade interactions for items related to amount of, type of, and time spent doing homework; opportunity to do homework at school; parents' assistance; students' beliefs about homework assignments and grading; and students' feelings about homework and school. The higher incidence of negative feelings and opinions from students in resource room programs suggests that students' understanding of assignments, the nature of the assignments, and the feedback given to students are important issues requiring closer evaluation. The results also suggest that changes in homework assignments and grading may make the transition from elementary to junior high school particularly difficult for students with special needs.

    This study evaluated the impact of a 2-wk required rotation in Physical Medicine and Rehabilitation (PM&R) on fourth-year medical students' knowledge of PM&R and attitude toward teamwork in patient care. Survey results on attitudes toward a team approach to patient care and knowledge in PM&R were compared prerotation and postrotation. One hundred thirty-eight fourth-year medical students participated in this 2-yr study. The combined response rates for the attitude and knowledge surveys were 62% and 56%, respectively. As measured by a pretest and posttest self-reported knowledge assessment, the rotation increased knowledge of PM&R (P ? 0.05). Four aspects of the rotation that were rated higher by students from the second year of the rotation were role and responsibility definition, incorporation of current literature, enhancement of clinical skills, and general rotation satisfaction. The rotation provides an experience for medical students to increase their knowledge of PM&R. PMID:22377823

  6. Required Data Management Training for Graduate Students in an Earth and Environmental Sciences Department

    Directory of Open Access Journals (Sweden)

    Bonnie L. Fong

    2015-06-01

    Full Text Available The increasing importance of data management in the sciences has led the Department of Earth & Environmental Sciences at a research intensive university to work closely with the Physical Sciences Librarian and Data Services Librarian on campus to provide mandatory training to its graduate students. Although integrating data management training into the graduate program curriculum may not be possible, there are still opportunities to ensure students learn such skills prior to graduating. This article describes the four approaches taken thus far – a seminar about basic data management during the department’s weekly seminar series, creation of a Data Profile form that students were asked to complete, an interactive workshop during the department’s annual retreat, and assistance with writing data management plans. Buy-in for requiring data management training was essential from both faculty and students and was possible because both groups understood the value of research data management skills. Also vital to the success of these approaches was how the subject specialist and data librarians leveraged their respective areas of expertise in a complementary fashion to address disciplinary as well as broader data-related concerns.

  10. Protein side-chain resonance assignment and NOE assignment using RDC-defined backbones without TOCSY data

    International Nuclear Information System (INIS)

    One bottleneck in NMR structure determination lies in the laborious and time-consuming process of side-chain resonance and NOE assignments. Compared to the well-studied backbone resonance assignment problem, automated side-chain resonance and NOE assignments are relatively less explored. Most NOE assignment algorithms require nearly complete side-chain resonance assignments from a series of through-bond experiments such as HCCH-TOCSY or HCCCONH. Unfortunately, these TOCSY experiments perform poorly on large proteins. To overcome this deficiency, we present a novel algorithm, called Nasca (NOE Assignment and Side-Chain Assignment), to automate both side-chain resonance and NOE assignments and to perform high-resolution protein structure determination in the absence of any explicit through-bond experiment to facilitate side-chain resonance assignment, such as HCCH-TOCSY. After casting the assignment problem into a Markov Random Field (MRF), Nasca extends and applies combinatorial protein design algorithms to compute optimal assignments that best interpret the NMR data. The MRF captures the contact map information of the protein derived from NOESY spectra, exploits the backbone structural information determined by RDCs, and considers all possible side-chain rotamers. The complexity of the combinatorial search is reduced by using a dead-end elimination (DEE) algorithm, which prunes side-chain resonance assignments that are provably not part of the optimal solution. Then an A* search algorithm is employed to find a set of optimal side-chain resonance assignments that best fit the NMR data. These side-chain resonance assignments are then used to resolve the NOE assignment ambiguity and compute high-resolution protein structures. Tests on five proteins show that Nasca assigns resonances for more than 90% of side-chain protons, and achieves about 80% correct assignments. The final structures computed using the NOE distance restraints assigned by Nasca have backbone RMSD 0.8–1.5 Å from the reference structures determined by traditional NMR approaches.

  11. Self-expression assignment as a teaching approach to enhance the interest of Kuwaiti women in biological sciences.

    Science.gov (United States)

    El-Sabban, Farouk

    2008-06-01

    Stimulating the interest of students in biological sciences necessitates the use of new teaching methods and motivating approaches. The idea of the self-expression assignment (SEA) has evolved from the prevalent environment at the College for Women of Kuwait University (Safat, State of Kuwait), a newly established college where the number of students is low and where students have varied backgrounds and interests and are being instructed biological sciences in English for the first time. This SEA requires each student to choose a topic among a long list of topics and interact with it in any way to produce a finished product without the interference of the course instructor. Students are told that the SEA will be graded based on their commitment, creative thinking, innovation in developing the idea, and finishing up of the chosen assignment. The SEA has been implemented in three introductory courses, namely, Biology, Introduction to Human Nutrition and Food Science, and The Human Body. Many interesting projects resulted from the SEA, and, based on an administered survey, students assessed this assignment very favorably. Students expressed their pleasure of experiencing freedom in choosing their own topics, interacting with such topics, learning more about them, and finishing up their projects. Students appreciated this type of exposure to biological sciences and expressed that such an experience enhanced their interest in such sciences. PMID:18539854

    Berenbrink, P; Goldberg, P; Martin, R; Berenbrink, Petra; Goldberg, Leslie Ann; Goldberg, Paul; Martin, Russell

    2004-01-01

    This paper studies a resource allocation problem introduced by Koutsoupias and Papadimitriou. The scenario is modelled as a multiple-player game in which each player selects one of a finite number of known resources. The cost to the player is the total weight of all players who choose that resource, multiplied by the ``delay'' of that resource. Recent papers have studied the Nash equilibria and social optima of this game in terms of the $L_\\infty$ cost metric, in which the social cost is taken to be the maximum cost to any player. We study the $L_1$ variant of this game, in which the social cost is taken to be the sum of the costs to the individual players, rather than the maximum of these costs. We give bounds on the size of the coordination ratio, which is the ratio between the social cost incurred by selfish behavior and the optimal social cost; we also study the algorithmic problem of finding optimal (lowest-cost) assignments and Nash Equilibria. Additionally, we obtain bounds on the ratio between alterna...

  10. The Art of Probability Assignment

    CERN Document Server

    Dimitrov, Vesselin I

    2012-01-01

    The problem of assigning probabilities when little is known is analized in the case where the quanities of interest are physical observables, i.e. can be measured and their values expressed by numbers. It is pointed out that the assignment of probabilities based on observation is a process of inference, involving the use of Bayes' theorem and the choice of a probability prior. When a lot of data is available, the resulting probability are remarkable insensitive to the form of the prior. In the oposite case of scarse data, it is suggested that the probabilities are assigned such that they are the least sensitive to specific variations of the probability prior. In the continuous case this results in a probability assignment rule wich calls for minimizing the Fisher information subject to constraints reflecting all available information. In the discrete case, the corresponding quantity to be minimized turns out to be a Renyi distance between the original and the shifted distribution.

    2007-01-01

    The UMLS is a terminological system that integrates many source terminologies. Each concept in the UMLS is assigned one or more semantic types from the Semantic Network, an upper level ontology for biomedicine. Due to the complexity of the UMLS, errors exist in the semantic type assignments. Finding assignment errors may unearth modeling errors. Even with sophisticated tools, discovering assignment errors requires manual review. In this paper we describe the evaluation of an auditing project of UMLS semantic type assignments. We studied the performance of the auditors who reviewed potential errors. We found that four auditors, interacting according to a multi-step protocol, identified a high rate of errors (one or more errors in 81% of concepts studied) and that results were sufficiently reliable (0.67 to 0.70) for the two most common types of errors. However, reliability was low for each individual auditor, suggesting that review of potential errors is resource-intensive. PMID:18693845

    Full Text Available Student Creativity Program or Program Kreativitas Mahasiswa (PKM is a prestigious annual scientific program for undergraduate students in Indonesia. The program runs since 2001 and held by DP2M Dikti, Ministry of Education and Culture. In 2013, over 7000 program proposals are funded on a maximum budget of IDR 12,500,000 each. This program aims to improve the quality of undergraduate students in order to become a part of community who have the academic and/ or professionals ability, who can implement, develop and disseminate science, technology and/ or the arts and enrich the national culture.1 Unfortunately, there is the corruption risk in the program. This study aims to investigate irregularities by students in PKM, revealing the root causes and offering solutions for policy reform in PKM. This study uses triangulation method (interview-observation-documentation for data gathering. Interviews were conducted to 30 students from 10 different universities in Indonesia. The study findings show that there are irregularities in PKM, such as marking up budget funds, futhermore, a lot of the remaining funds being used for private purposes. These occur because evaluators never ask about the remaining funds at the time of monitoring and evaluation (monev. Still, the budget does not include honorarium as a reward for the student’s hard work. In fact, the misuse of budget allocation for private purpose is not appropriate because it is contrary to Article 2 of Law No. 31/ 1999. A total of 26 out of 30 students agreed if there is honorarium in PKM, so there will be a giving back for their energy, time and thought. This study is very potential for removing irregularities and reforming policy of PKM in Indonesia, so the program is no longer contaminated by the corruption risk.

  7. Heuristic for Task-Worker Assignment with Varying Learning Slopes

    Directory of Open Access Journals (Sweden)

    2010-04-01

    Full Text Available Fashion industry has variety products, so the multi-skilled workers are required to improve flexibility in production and assignment. Generally the supervisor will assign task to the workers based on skill and skill levels of worker. Since in fashion industry new product styles are launched more frequently and the order size tends to be smaller, the workers always learn when the raw material and the production process changes. Consequently they require less time to produce the succeeding units of a task based on their learning ability. Since the workers have both experience and inexperience workers, so each worker has different skill level and learning ability. Consequently, the assignment which assumed constant skill level is not proper to use. This paper proposes a task-worker assignment considering worker skill levels and learning abilities. Processing time of each worker changes along production period due to a worker learning ability. We focus on a task-worker assignment in a fashion industry where tasks are ordered in series; the number of tasks is greater than the number of workers. Therefore, workers can perform multiple assignments followed the precedence restriction as an assembly line balancing problem. The problem is formulated in an integer linear programming model with objective to minimize makespan. A heuristic is proposed to determine the lower bound (LB and the upper bound (UB of the problem and the best assignment is determined. The performance of the heuristic method is tested by comparing quality of solution and computational time to optimal solutions.

    Optimal assignment of classes to classrooms \\cite{dickey}, design of DNA microarrays \\cite{carvalho}, cross species gene analysis \\cite{kolar}, creation of hospital layouts cite{elshafei}, and assignment of components to locations on circuit boards \\cite{steinberg} are a few of the many problems which have been formulated as a quadratic assignment problem (QAP). Originally formulated in 1957, the QAP is one of the most difficult of all combinatorial optimization problems. Here, we use statistical mechanical methods to study the asymptotic behavior of problems in which the entries of at least one of the two matrices that specify the problem are chosen from a random distribution $P$. Surprisingly, this case has not been studied before using statistical methods despite the fact that the QAP was first proposed over 50 years ago \\cite{Koopmans}. We find simple forms for $C_{\\rm min}$ and $C_{\\rm max}$, the costs of the minimal and maximum solutions respectively. Notable features of our results are the symmetry of ...

  14. Scaling through pair-wise comparison method in required characteristics of students applying for post graduate programs

    Nese Güler

    2009-04-01

    Full Text Available The Aim and Significance of the Research: The characteristics that lecturers wish students applying for post-graduate programs should possess are determined in this paper quantitatively through pairwise comparisons according to the lecturers' responses.  The fact that resources and studies concerning the issue of scaling are scarcely available has been the most significant driving force for researchers to conduct research on this issue. It is believed that this research will make contributions to the field of scaling, which has limited number of studies. Since this research is a work of scaling which is rarely seen in the field of education, it is thought that the research is significant. Method of Research: The research was conducted on the 129 lecturers working in the different departments of Hacettepe University in the fall and spring semesters in the 2006 - 2007 academic year. At the stage of preparing the tool of measurement, the 7 characteristics that were required students should possess for selection to post-graduate education programs were determined and a tool of measurement through which pairwise comparisons would be made were designed.  Consequently, the scale value for each characteristic was marked on the line of numbers. Findings and Comments: According to the pairwise comparison, academic achievement score is in the first order. This is followed by the score gained in the interview, the purpose in entering the department, their level of English proficiency, ALES score, whether or not they are originally the students of the department and whether or not they have a letter of reference, respectively. According to results, when the students are selected to the post-graduate education programs it is suggested that the weighting of the students' characteristics required is made by considering this order. In addition to this, it is thought that studying with different samples and different scaling methods provide important contribution to the field.

  16. Mapping Learning Outcomes and Assignment Tasks for SPIDER Activities

    Directory of Open Access Journals (Sweden)

    Lyn Brodie

    2011-05-01

    Full Text Available Modern engineering programs have to address rapidly changing technical content and have to enable students to develop transferable skills such as critical evaluation, communication skills and lifelong learning. This paper introduces a combined learning and assessment activity that provides students with opportunities to develop and practice their soft skills, but also extends their theoretical knowledge base. Key tasks included self directed inquiry, oral and written communication as well as peer assessment. To facilitate the SPIDER activities (Select, Prepare and Investigate, Discuss, Evaluate, Reflect, a software tool has been implemented in the learning management system Moodle. Evidence shows increased student engagement and better learning outcomes for both transferable as well as technical skills. The study focuses on generalising the relationship between learning outcomes and assignment tasks as well as activities that drive these tasks. Trail results inform the approach. Staff evaluations and their views of assignments and intended learning outcomes also supported this analysis.

    Festini, Sara B; Hartley, Alan A; Tauber, Sarah K; Rhodes, Matthew G

    2013-01-01

    Names are more difficult to remember than other personal information such as occupations. The current research examined the influence of assigned point value on memory and metamemory judgements for names and occupations to determine whether incentive can improve recall of proper names. In Experiment 1 participants studied face-name and face-occupation pairs assigned 1 or 10 points, made judgements of learning, and were given a cued recall test. High-value names were recalled more often than low-value names. However, recall of occupations was not influenced by value. In Experiment 2 meaningless nonwords were used for both names and occupations. The name difficulty disappeared, and value influenced recall of both names and occupations. Thus value similarly influenced names and occupations when meaningfulness was held constant. In Experiment 3 participants were required to use overt rote rehearsal for all items. Value did not boost recall of high-value names, suggesting that differential processing could not be implemented to improve memory. Thus incentives may improve memory for proper names by motivating people to engage in selective rehearsal and effortful elaborative processing. PMID:23210532

Methods A 51 case, 158-question, multidisciplinary paper was constructed to assess clinical reasoning in 5th-year. 10–16 experts in each of 7 discipline-based reference panels answered questions on-line. A multidisciplinary group considered reference panel data and data from a volunteer group of 6th Years, who sat the same test, to determine the passing score for the 5th Years. Results The mean (SD scores were 63.6 (7.6 and 68.6 (4.8 for the 6th Year (n?=?23, alpha?=?0.78 and and 5th Year (n?=?132, alpha =0.62 groups (p? Conclusions The SCT may be a useful method to assess clinical reasoning in medical students in multidisciplinary summative assessments. Substantial investment in training of faculty and students and in the development of questions is required.

  14. Assigned shares in compensation for radiation-related cancers

    International Nuclear Information System (INIS)

    The preparation of radioepidemiologic tables requires extensive mathematical modeling because matters such as sex, size of dose, age at exposure, type of cancer, and age at diagnosis must be taken into account. The limited data require many assumptions about the quantitative relationship between radiation dose and the age-specific incidence rate of cancer. After partitioning a population into reference sets based on age at exposure, size of dose, type of cancer, etc., an assigned share is computed for each reference set and then assigned to all of its members. The assigned share represents the fraction of the cancer cases in the reference set that are attributed to the radiation dose. Because the population can be partitioned in many ways, each individual's assigned share depends on the partition used and will change with different partitions. Options for modeling and limitations in epidemiologic data lead to considerable uncertainties in estimates of assigned charges that have been scientifically evaluated. In contrast, the uncertainties associated with the current approach for determining the likelihood a cancer was caused by radiation have not been appraised but are likely to be even greater than those associated with the tables

  16. Interactive Level Design for iOS Assignment Delivery: A Case Study

    Directory of Open Access Journals (Sweden)

    Anson Brown

    2014-02-01

    Full Text Available This paper presents an application of an iOS-based online gaming assignment in a real classroom. The core concept of the project is a gameplay environment involving two players that have full control over creation and modification of levels. This level design mechanism was implemented in an iOS-based game in the area of genetics and based on an existing written assignment. The game includes support for both instructors, who have the ability to create and post assignments and students, who can take the assignments. Two trials of the iOS application consisted of in-class testing of twenty- one students. Students first took the original paper assignment, followed by the iOS version. Start times, end times, and grades were recorded for both versions. A comprehensive study of the grades and times for the iOS version of the assignment versus the paper version was conducted and is presented in this paper. Our Study showed that the iOS version was completed much faster in nearly every case while a strong delivery mechanism is needed to ensure student grades and completion of the assignment will not be affected. These results are not unexpected due to some major difference between the two formats. Future updates and additions will address any currently existing issues.

  17. Solving multiconstraint assignment problems using learning automata.

    Science.gov (United States)

    Horn, Geir; Oommen, B John

    2010-02-01

    This paper considers the NP-hard problem of object assignment with respect to multiple constraints: assigning a set of elements (or objects) into mutually exclusive classes (or groups), where the elements which are "similar" to each other are hopefully located in the same class. The literature reports solutions in which the similarity constraint consists of a single index that is inappropriate for the type of multiconstraint problems considered here and where the constraints could simultaneously be contradictory. This feature, where we permit possibly contradictory constraints, distinguishes this paper from the state of the art. Indeed, we are aware of no learning automata (or other heuristic) solutions which solve this problem in its most general setting. Such a scenario is illustrated with the static mapping problem, which consists of distributing the processes of a parallel application onto a set of computing nodes. This is a classical and yet very important problem within the areas of parallel computing, grid computing, and cloud computing. We have developed four learning-automata (LA)-based algorithms to solve this problem: First, a fixed-structure stochastic automata algorithm is presented, where the processes try to form pairs to go onto the same node. This algorithm solves the problem, although it requires some centralized coordination. As it is desirable to avoid centralized control, we subsequently present three different variable-structure stochastic automata (VSSA) algorithms, which have superior partitioning properties in certain settings, although they forfeit some of the scalability features of the fixed-structure algorithm. All three VSSA algorithms model the processes as automata having first the hosting nodes as possible actions; second, the processes as possible actions; and, third, attempting to estimate the process communication digraph prior to probabilistically mapping the processes. This paper, which, we believe, comprehensively reports the pioneering LA solutions to this problem, unequivocally demonstrates that LA can play an important role in solving complex combinatorial and integer optimization problems.

  18. Incorporating Inquiry into Upper-Level Undergraduate Homework Assignments: The Mini-Journal

    Science.gov (United States)

    Whittington, Alan; Speck, Angela; Witzig, Stephen; Abell, Sandra

    2010-05-01

    The US National Science Education Standards (2000) state that science should be taught through inquiry. The five essential features of classroom inquiry are that the leaner (i) engages in scientifically oriented questions, (ii) gives priority to evidence in responding to questions, (iii) formulates explanations from evidence, (iv) connects explanations to scientific knowledge, and (v) communicates and justifies explanations. One difficulty in achieving this vision at the university level lies in the common perception that inquiry be fully open and unstructured, and that its implementation will be impractical due to time and material constraints. In an NSF-funded project, "CUES: Connecting Undergraduates to the Enterprise of Science," faculty developed new inquiry-based laboratory curriculum materials using a "mini-journal" approach, which is designed as an alternative to the cookbook laboratory and represents the way that scientists do science. Here we adapt this approach to a homework assignment in an upper-level Planetary Science class, and show that inquiry is achievable in this setting. Traditional homeworks in this class consisted of problem sets requiring algebraic manipulation, computation, and in most cases an appraisal of the result Longer questions are broken down into chunks worth 1 to 4 points. In contrast, the mini-journal is a short article that is modeled in the way that scientists do and report science. It includes a title, abstract, introduction (with clear statement of the problem to be tackled), a description of the methods, results (presented as both tables and graphs), a discussion (with suggestions for future work) and a list of cited work. Students devise their research questions and hypothesis from the paper based on a logical next step in the investigation. Guiding questions in the discussion can assist the students ("it would be interesting to evaluate the effect of ..."). Students submit their own minijournal, using the same journal-style format. A detailed grading rubric was supplied with the mini-journal, with credit given for formatting, accuracy of calculation, and quality of intepretation and discussion. In the examples we present, research is conducted via spreadsheet modeling, where the students develop their own spreadsheets. The key differences between the old and new formats include (i) the active participation of the students in defining the problem that they will pursue, (ii) the open-ended nature of the inquiry, such that students need to recognize when they have enough information to answer their question, (iii) presentation of results in graphical and tabular formats, and (iv) a written discussion of their findings. Based on detailed student and instructor feedback, our conclusions are: (i) Limited inquiry is achievable in upper-level science homework assignments, and is transferable to other topics and classes (ii) Students experience discomfort on being presented with an open-ended assignment, but like the freedom to define their own homework problem (iii) Students recognize that the reading, writing and critical thinking skills employed in the minijournal format increase their understanding (iv) Students suggest a combination of minijournal and traditional homework formats in this class, or replacing midterm exams with minijournals (v) Student written comments are far more useful than Likert scale responses in assessing instructional techniques and effectiveness

  20. Contiguous IP Address Assignment Strategy for Small-Scale MANET

    Science.gov (United States)

    Hwang, Jin-Ok; Min, Sung-Gi

    Most routing protocols in MANET use IP addresses as one of the most important routing information. To implement the routing protocol of MANET, the IP assignment in MANET should be solved. Allocating IP addresses is one of current key issues in the MANET, due to the absence of a centralized agent server. Previous methods require a large address space or can not use all the IP addresses of the given IP address space. For that reason, many IP addresses remain unused. To resolve this, we propose an IP address assignment protocol that uses the contiguous IP address assignment strategy without unused IP addresses. Simulations perform on ns-2 and confirm the viability of our protocol.

  14. Proton resonance assignments of horse ferricytochrome c

    International Nuclear Information System (INIS)

    Two-dimensional nuclear magnetic resonance spectroscopy (2D NMR) was used to obtain extensive resonance assignments in the 1H NMR spectrum of horse ferricytochrome c. Assignments were made for the main-chain and C? protons of 102 residues (all except Pro-44 and Gly-84) and the majority of side-chain protons. As starting points for the assignment of the oxidized protein, a limited set of protons was initially assigned by use of 2D NMR magnetization transfer methods to correlate resonances in the oxidized form with assigned resonances in the reduced form. Given the complexity of the spectrum due to the size of this protein (104 residues) and its paramagnetic center, the initial search for side-chain spin systems in J-correlated spectra was successful only for the simplest side chains, but the majority of NH-C?H-C?H subspin systems (NAB sets) could be identified at this stage. The subsequent search for sequential NOE connectivities focused on NAB sets, with use of previously assigned residues to place NOE-connected segments within the amino acid sequence. Selective proton labeling of either the slowly or the rapidly exchanging amide sites was used to simplify the spectra, and systematic work at two temperatures was used to resolve ambiguities in the 2D NMR spectra. These approaches, together with the use of magnetization transfer methods to correlate reduced and oxidized cytochrome c spectra, provide multiple cross-checks to verify assignments

  14. Mini-Journals: Incorporating Inquiry, Quantitative Skills and Writing into Homework Assignments for Geochemistry and Planetary Science

    Science.gov (United States)

    Whittington, A. G.; Speck, A.; Witzig, S.

    2011-12-01

    As part of an NSF-funded project, "CUES: Connecting Undergraduates to the Enterprise of Science," new inquiry-based homework materials were developed for two upper-level classes at the University of Missouri: Geochemistry (required for Geology majors, fulfills the computing requirement by having 50% of the grade come from five spreadsheet-based homework assignments), and Solar System Science (open to seniors and graduate students, co-taught and cross-listed between Geology and Physics & Astronomy). Inquiry involves activities where the learner engages in scientifically oriented questions, gives priority to evidence in responding to questions, formulates explanations from evidence, connects explanations to scientific knowledge, and communicates and justifies explanations. We engage students in inquiry-based learning by presenting homework exercises as "mini-journal" articles that follow the format of a scientific journal article, including a title, authors, abstract, introduction, methods, results, discussion and citations to peer-reviewed literature. The mini-journal provides a scaffold and serves as a springboard for students to develop and carry out their own follow-up investigation. They then present their findings in the form of their own mini-journal. Mini-journals replace traditional homework problem sets with a format that more directly reflects and encourages scientific practice. Students are engaged in inquiry-based homework which encompass doing, thinking, and communicating, while the mini-journal allows the instructor to contain lines of inquiry within the limits posed by available resources. In the examples we present, research is conducted via spreadsheet modeling, where the students develop their own spreadsheets. Example assignments from Geochemistry include "Trace Element Partitioning During Mantle Melting and MORB Crystallization" and "Isotopic Investigations of Crustal Evolution in the Midcontinent US". The key differences between the old and new formats include (i) active participation of the students in defining the question/problem that they will pursue, within well-defined boundaries, (ii) open-ended nature of the inquiry, so that students need to recognize when they have enough information to answer their question, (iii) extensive spreadsheet manipulation and presentation of results in graphical and tabular formats, and (iv) a written discussion of their findings. Grading is weighted more towards how the problem was addressed, and how findings are presented and interpreted, and less on actual numerical answers. Survey responses from students indicate that they experience discomfort on being presented with an open-ended assignment, but like the freedom to define their own problem. Students also recognize that reading, writing and critical thinking skills employed in the minijournal format increase their understanding of content. The combination of calculation and writing components make these assignments particularly useful for classes designated as "computer-based", and/or "writing intensive" (or similar designations).

  15. Student Blogging about Physics

    Daniels, Karen E.

    2010-09-01

    In traditional introductory physics classes, there is often limited opportunity for students to contribute their own ideas, interests, and experiences as they engage with the subject matter. This situation is exacerbated in university lecture-format classes, where students may not feel comfortable speaking during class. In the last few years, Internet blogs have become a decentralized format for diarists, independent journalists, and opinion makers to both post entries and allow commentary from their readers. Below, I will describe some techniques for using student blogging about physics to engage students from two different classroom environments: a calculus-based introductory mechanics class for scientists and engineers, and an honors seminar for first-year students. These assignments required them to make their own connections between classroom knowledge and situations where it might find applications. A second goal of including blogging in the introductory physics course was to induce students to write about the physics content of the class in a more substantive way than was previously part of the class.

  16. Flexible taxonomic assignment of ambiguous sequencing reads

    Directory of Open Access Journals (Sweden)

    Jansson Jesper

    2011-01-01

    Full Text Available Abstract Background To characterize the diversity of bacterial populations in metagenomic studies, sequencing reads need to be accurately assigned to taxonomic units in a given reference taxonomy. Reads that cannot be reliably assigned to a unique leaf in the taxonomy (ambiguous reads are typically assigned to the lowest common ancestor of the set of species that match it. This introduces a potentially severe error in the estimation of bacteria present in the sample due to false positives, since all species in the subtree rooted at the ancestor are implicitly assigned to the read even though many of them may not match it. Results We present a method that maps each read to a node in the taxonomy that minimizes a penalty score while balancing the relevance of precision and recall in the assignment through a parameter q. This mapping can be obtained in time linear in the number of matching sequences, because LCA queries to the reference taxonomy take constant time. When applied to six different metagenomic datasets, our algorithm produces different taxonomic distributions depending on whether coverage or precision is maximized. Including information on the quality of the reads reduces the number of unassigned reads but increases the number of ambiguous reads, stressing the relevance of our method. Finally, two measures of performance are described and results with a set of artificially generated datasets are discussed. Conclusions The assignment strategy of sequencing reads introduced in this paper is a versatile and a quick method to study bacterial communities. The bacterial composition of the analyzed samples can vary significantly depending on how ambiguous reads are assigned depending on the value of the q parameter. Validation of our results in an artificial dataset confirm that a combination of values of q produces the most accurate results.

    2016-01-01

    In the literature we found many studies that confirmed our concerns about nursing students' poor maths skills that directly impact on their ability to correctly calculate drug dosages with very serious consequences for patient safety. The aim of our study was to explore where students had most difficulty and identify appropriate educational interventions to bridge their mathematical knowledge gaps. This was a quali-quantitative descriptive study that included a sample of 726 undergraduate nursing students. We identified exactly where students had most difficulty and identified appropriate educational interventions to bridge their mathematical knowledge gaps. We found that the undergraduate nursing students mainly had difficulty with basic maths principles. Specific learning interventions are needed to improve their basic maths skills and their dosage calculation skills. For this purpose, we identified safeMedicate and eDose™ (Authentic World Ltd.), only that they are only available in English. In the near future we hope to set up a partnership to work together on the Italian version of these tools. PMID:26347449

  18. Requirements in the Overseas Employment and Domestic Connected Education for Radiological Technologists : Refers to Students Enrolled in the Department of Radiation

    International Nuclear Information System (INIS)

    This study investigated the realities of information acquirements and its requirements in the overseas employment and domestic connected education for students at the department of radiation in order to provide basic information for developing the standard educational curriculum for future internationalization in the education of radiation and presenting its direction. The investigation implemented in this study was performed through a questionnaire with 688 students enrolled in the department of radiation. The conclusion of the investigation is summarized as follows : The answers for the question of 'No acquirements in the information of the overseas employment and connected education for radiological technologists' were 487 students (70.8%), and the reason that 'There are no chances in related education' was the highest rate, 424 students (61.6%), of the answers. In the education for the overseas employment, the answers for the question of 'Select a connected education program in school instead of study abroad' were the highest rate, 436 students (63.4%). The most concerned country for the overseas employment was 'Australia', 247 students (35.9%). As a result, answers for the interest, participation, need, and hope for the overseas employment showed high rates even though they demonstrated a low recognition level in the overseas employment. In addition, it is necessary to strategically plan an education program for this issue because all participants agree with the current stream.

  19. Protein secondary structure assignment revisited: a detailed analysis of different assignment methods

    Directory of Open Access Journals (Sweden)

    de Brevern Alexandre G

    2005-09-01

    Full Text Available Abstract Background A number of methods are now available to perform automatic assignment of periodic secondary structures from atomic coordinates, based on different characteristics of the secondary structures. In general these methods exhibit a broad consensus as to the location of most helix and strand core segments in protein structures. However the termini of the segments are often ill-defined and it is difficult to decide unambiguously which residues at the edge of the segments have to be included. In addition, there is a "twilight zone" where secondary structure segments depart significantly from the idealized models of Pauling and Corey. For these segments, one has to decide whether the observed structural variations are merely distorsions or whether they constitute a break in the secondary structure. Methods To address these problems, we have developed a method for secondary structure assignment, called KAKSI. Assignments made by KAKSI are compared with assignments given by DSSP, STRIDE, XTLSSTR, PSEA and SECSTR, as well as secondary structures found in PDB files, on 4 datasets (X-ray structures with different resolution range, NMR structures. Results A detailed comparison of KAKSI assignments with those of STRIDE and PSEA reveals that KAKSI assigns slightly longer helices and strands than STRIDE in case of one-to-one correspondence between the segments. However, KAKSI tends also to favor the assignment of several short helices when STRIDE and PSEA assign longer, kinked, helices. Helices assigned by KAKSI have geometrical characteristics close to those described in the PDB. They are more linear than helices assigned by other methods. The same tendency to split long segments is observed for strands, although less systematically. We present a number of cases of secondary structure assignments that illustrate this behavior. Conclusion Our method provides valuable assignments which favor the regularity of secondary structure segments.

  2. Method for assigning sites to projected generic nuclear power plants

    International Nuclear Information System (INIS)

    Pacific Northwest Laboratory developed a method for forecasting potential locations and startup sequences of nuclear power plants that will be required in the future but have not yet been specifically identified by electric utilities. Use of the method results in numerical ratings for potential nuclear power plant sites located in each of the 10 federal energy regions. The rating for each potential site is obtained from numerical factors assigned to each of 5 primary siting characteristics: (1) cooling water availability, (2) site land area, (3) power transmission land area, (4) proximity to metropolitan areas, and (5) utility plans for the site. The sequence of plant startups in each federal energy region is obtained by use of the numerical ratings and the forecasts of generic nuclear power plant startups obtained from the EIA Middle Case electricity forecast. Sites are assigned to generic plants in chronological order according to startup date

  3. Computational Assignment of Chemical Shifts for Protein Residues

    CERN Document Server

    Bratholm, Lars A

    2013-01-01

    Fast and accurate protein structure prediction is one of the major challenges in structural biology, biotechnology and molecular biomedicine. These fields require 3D protein structures for rational design of proteins with improved or novel properties. X-ray crystallography is the most common approach even with its low success rate, but lately NMR based approaches have gained popularity. The general approach involves a set of distance restraints used to guide a structure prediction, but simple NMR triple-resonance experiments often provide enough structural information to predict the structure of small proteins. Previous protein folding simulations that have utilised experimental data have weighted the experimental data and physical force field terms more or less arbitrarily, and the method is thus not generally applicable to new proteins. Furthermore a complete and near error-free assignment of chemical shifts obtained by the NMR experiments is needed, due to the static, or deterministic, assignment. In this ...

  4. Feedback stabilisation of switched systems via iterative approximate eigenvector assignment

    CERN Document Server

    Haimovich, Hernan

    2010-01-01

    This paper presents and implements an iterative feedback design algorithm for stabilisation of discrete-time switched systems under arbitrary switching regimes. The algorithm seeks state feedback gains so that the closed-loop switching system admits a common quadratic Lyapunov function (CQLF) and hence is uniformly globally exponentially stable. Although the feedback design problem considered can be solved directly via linear matrix inequalities (LMIs), direct application of LMIs for feedback design does not provide information on closed-loop system structure. In contrast, the feedback matrices computed by the proposed algorithm assign closed-loop structure approximating that required to satisfy Lie-algebraic conditions that guarantee existence of a CQLF. The main contribution of the paper is to provide, for single-input systems, a numerical implementation of the algorithm based on iterative approximate common eigenvector assignment, and to establish cases where such algorithm is guaranteed to succeed. We inc...

    2015-11-01

    Full Text Available The correlation between academic curricula and labor market requirements is a key issue of modern education and a primary pillar of the Bologna process. Romanian universities have adjusted in the last decade or so their curricula and academic offer to the labor market needs. Recently, the field of Project Management has gained more prominence in the Romanian labor market, which makes one enquire about the academic preparation that Master students get in this area of study. Our research aims at shedding light on the way competences, abilities and academic curricula in Economics specializations are related to the Romanian labor market needs, with a focus in the field of Project Management. We are conducting a survey among Master students of two renowned Romanian universities - Bucharest University of Economic Studies and Lucian Blaga University of Sibiu. A number of two samples of students will be selected to conduct the survey, one for each university. The students and all enrolled in Master program with a specialization in Economics. Our study is useful for both academics and labor market, as interested bodies from both sides might learn more about the perception of future graduates on the academic program they follow and the competences and abilities they gain, on one hand, and on the labor market realities in terms of requirements for future employees, on the other hand.

    Castillo, Andrés M; Bernal, Andrés; Patiny, Luc; Wist, Julien

    2015-08-01

    We present a method for the automatic assignment of small molecules' NMR spectra. The method includes an automatic and novel self-consistent peak-picking routine that validates NMR peaks in each spectrum against peaks in the same or other spectra that are due to the same resonances. The auto-assignment routine used is based on branch-and-bound optimization and relies predominantly on integration and correlation data; chemical shift information may be included when available to fasten the search and shorten the list of viable assignments, but in most cases tested, it is not required in order to find the correct assignment. This automatic assignment method is implemented as a web-based tool that runs without any user input other than the acquired spectra. PMID:26053353

  16. A Sequence of Assignments to Teach Object-Oriented Programming: a Constructivism Design-First Approach

    Directory of Open Access Journals (Sweden)

    Kleanthis C. THRAMBOULIDIS

    2003-04-01

    Full Text Available A constructivism-based approach to teach the object-oriented (OO programming paradigm in introductory computer courses was developed and used for several years. A multi-entity system from every-day life was adopted, to exploit the novice programmer's existing knowledge and build on it the OO conceptual framework. A sequence of assignments has been designed and developed to allow students exposed to this approach to experiment with Java programming and see how the OO conceptual framework is implemented. In this paper, this sequence of assignments is presented, discussed and evaluated in the context of the defined approach. The set of assignments that is based on a software-engineering-centered view and more precisely on a design-first approach, comes with the description of the strategy and graded hints that lead students to the final solution. Although it was first implemented as supplementary material, it quickly became the core component of the course.

This procedure consists in a bipartite agreement (free of charge or for consideration) concluded between the original creditor (acting as assignor) and the new creditor (acting as assignee); the debtor is not part of the agreement. Nevertheless, according to the provisions of the New Civil Code1, there are certain situations when the consent of the debtor is required (e.g. the ...

    Full Text Available Weapon Target Assignment (WTA is the assignment of friendly weapons to the hostile targets in order to protect friendly assets or destroy the hostile targets and considered as a NP-complete problem. Thus, it is very hard to solve it for real time or near-real time operational needs. In this study, genetic algorithm (GA, tabu search (TS, simulated annealing (SA and Variable Neighborhood Search (VNS combinatorial optimization techniques are applied to the WTA problem and their results are compared with each other and also with the optimized GAMS solutions. Algorithms are tested on the large scale problem instances. It is found that all the algorithms effectively converge to the near global optimum point(s (a good quality and the efficiency of the solutions (speed of solution might be improved according to the operational needs. VNS and SA solution qualities are better than both GA and TS.

    2015-06-01

    We have reached a conundrum in assigning cause of death for sudden unexpected infant deaths. We summarize the discordant perspectives and approaches and how they have occurred, and recommend a pathway toward improved consistency. This lack of consistency affects pediatricians and other health care professionals, scientific investigators, medical examiners and coroners, law enforcement agencies, families, and support or advocacy groups. We recommend that an interdisciplinary international committee be organized to review current approaches for assigning cause of death, and to identify a consensus strategy for improving consistency. This effort will need to encompass intrinsic risk factors or infant vulnerability in addition to known environmental risk factors including unsafe sleep settings, and must be sufficiently flexible to accommodate a progressively expanding knowledge base.

  20. Proton resonance assignments of horse ferrocytochrome c

    International Nuclear Information System (INIS)

    Two-dimensional nuclear magnetic resonance (NMR) spectroscopy was used to assign the proton resonances of horse ferrocytochrome c. Assignments were based on the main chain directed (MCD) and sequential assignment procedures. The fundamental units of the MCD approach, the main-chain NH-C?H-C?H J-coupled subspin systems of each amino acid residue (NAB sets), were defined by analysis of direct and relayed coherence transfer spectra. Recognition of main-chain NOE connectivity patterns specified in the MCD algorithm them allowed NAB sets to be aligned in their proper juxtaposition within secondary structural units. The units of secondary structure were placed within the polypeptide sequence of identification of a small number of side-chain J-coupled spin systems, found by direct recognition in 2D spectra of some J-coupled spin systems and by pairwise comparisons of the J-correlated spectra of six homologous cytochromes c having a small number of known amino acid differences. The placement of a given segment in this way defines the amino acid identity of all its NAB sets. This foreknowledge allowed the vast majority of the side-chain resonances to be discerned in J-correlated spectra. Extensive confirmation of the assignments derives internally from multiple main-chain NOE connectivities and their consistency following temperature-induced changes of the chemical shifts of NOE-correlated protons. The observed patterns of main-chain NOEs provide some structural information and suggest small but potentially significant differences between the solution structure observed by NMR and that defined earlier in crystallographic studies at 2.8-angstrom resolution

    There is considerable and widespread concern about whether CEOs are appropriately punished for poor performance. The empirical literature on CEO turnover documents that CEOs are indeed more likely to be forced out if their performance is poor relative to the industry average. However, CEOs are also more likely to be replaced if the industry is doing badly. We show that these empirical patterns are natural and efficient outcomes of a competitive assignment model in which CEOs and firms form...

  8. Assessing and helping challenging students: Part One, Why do some students have difficulty learning?

    Science.gov (United States)

    Hendricson, William D; Kleffner, John H

    2002-01-01

    When students struggle with routine assignments and fall behind classmates, a busy teacher may pigeonhole them as slow, give up on them, or become frustrated from failed efforts to bring them up to speed. Well-intentioned efforts to help struggling students by providing repetitions of the same experiences may fail because the specific cause of the sub-par performance was not identified. Six potential causes of inadequate student performance can serve as a diagnostic framework to help teachers pinpoint why a student is struggling academically: 1) cognitive factors, including poorly integrated, compartmentalized information, poor metacognition that hinders the student's ability to monitor and self-correct performance, bona fide learning disabilities that require professional assessment and treatment, and sensory-perceptual difficulties that may hinder performance in certain health care disciplines; 2) ineffective study habits, which are more common among professional students than faculty realize; 3) an inadequate educational experience (unclear objectives, poorly organized instruction, absence of coaching and timely feedback) or a punitive environment in which students avoid approaching instructors for assistance; 4) distraction due to nonacademic issues such as social relationships, health of a spouse, or employment; 5) dysfunctional levels of defensiveness that hinder student-teacher communication; and 6) underlying medical conditions that may affect student attentiveness, motivation, energy, and emotional balance. The objective of this article is to help faculty recognize potential underlying causes of a student's learning problems. Strategies for helping the academically struggling student are also introduced for several of these etiologies. PMID:12358100

  13. Heuristics to solve the integrated airline crew assignment problem

    Scientific Electronic Library Online (English)

    Wagner P., Gomes; Nicolau D. F., Gualda.

    2015-01-01

    Full Text Available A typical problem related to airline crew management consists of optimally assigning the required crew members to planned flights for a given period of time, while complying with a variety of labor regulations, safety rules and policies of the airline. This problem, called crew assignment problem (C [...] AP), is of the NPHard class. So, it is usually divided into two independent subproblems, crew pairing problem (CPP) and crew rostering problem (CRP), modeled and solved sequentially. This division does not provide a global treatment to the CAP in terms of total cost and quality of the final solution. The state of the art involves the integrated solution of CAP, with both subproblems (CPP and CRP) solved simultaneously. It still requires high computational effort. Its combinatorial nature makes it difficult (or even impossible) to be solved by exact methods. The methodology proposed in this research provides an integrated solution of the CAP with heuristic procedures. The methodology was tested to solve instances related to small and medium-sized Brazilian airlines. The results were also compared with those obtained through an exact model adapted from the literature.

  14. Interval Assignment for Volumes with Holes

    Energy Technology Data Exchange (ETDEWEB)

    BENZLEY, STEVEN; MITCHELL, SCOTT A.; SHEPHERD, JASON F.

    1999-09-07

    This paper presents a new technique for automatically detecting interval constraints for swept volumes with holes. The technique finds true volume constraints that are not necessarily imposed by the surfaces of the volume. A graphing algorithm finds independent, parallel paths of edges from source surfaces to target surfaces. The number of intervals on two paths between a given source and target surface must be equal; in general, the collection of paths determine a set of linear constraints. Linear programming techniques solve the interval assignment problem for the surface and volume constraints simultaneously.

    In this paper the characteristic ratios and generalized time constant are defined for all-pole commensurate fractional order systems. The sufficient condition for stability of these systems in terms of their characteristic ratios is obtained. Also an analytical approach for characteristic ratio assignment (CRA) to have a non-overshooting fast closed loop step response is introduced. The proposed CRA method is then employed to design a fractional order controller. Computer simulation results are presented to illustrate the performance of the CRA based designed fractional order controllers. PMID:20619834

    A stereochemical feature of the hibarimicins is a central biaryl (HMP-Y6) or aryl-quinone (hibarimicinone) incorporated as a single atropodiastereomer. Herein, a chiral resolution and deracemization process to access optically enriched biaryls aR-3 and aS-3 is described. From these atropoenantiomers the BCD-EFG ring system of HMP-Y6 is constructed [(+)-aR-7]. Comparison of CD spectra of aR-7 to HMP-Y6 leads to the assignment of HMP-Y6 and hibarimicin B atropoisomers as aR and aS, respectively. PMID:21812391

    Directory of Open Access Journals (Sweden)

    Fang Ye

    2011-06-01

    Full Text Available The interference constraints of genetic spectrum assignment model in cognitive radio networks are analyzed in this paper. An improved genetic spectrum assignment model is proposed. The population of genetic algorithm is divided into two sets, the feasible spectrum assignment strategies and the randomly updated spectrum assignment strategies. The penalty function is added to the utility function to achieve the spectrum assignment strategy that satisfies the interference constraints and has better fitness. The proposed method is applicable in both the genetic spectrum assignment model and the quantum genetic spectrum assignment mode. It can ensure the randomness of partial chromosomes in the population to some extent, and reduce the computational complexity caused by the constraints-free procedure after the update of population. Simulation results show that the proposed method can achieve better performance than the conventional genetic spectrum assignment model and quantum genetic spectrum assignment model

    Teacher-Child Interaction Training (TCIT), adapted from Parent-Child Interaction Therapy (PCIT), is a classroom-based program designed to provide teachers with behavior management skills that foster positive teacher-student relationships and to improve student behavior by creating a more constructive classroom environment. The purpose of this pilot study was to evaluate TCIT in more classrooms than previously reported in the literature, with older children than previously reported, using random assignment of classrooms to TCIT or to a no-TCIT control condition and conducting all but two sessions within the classroom to enhance feasibility. Participants included 11 kindergarten and first grade classroom teachers and their 118 students from three urban, public schools in Manhattan, with five classrooms randomly assigned to receive TCIT and six to the no-TCIT control condition. Observations of teacher skill acquisition were conducted before, during, and after TCIT for all 11 teachers, and teacher reports of student behavior were obtained at these same time points. Teacher satisfaction with TCIT was assessed following training. Results suggested that after receiving TCIT, teachers increased rates of positive attention to students' appropriate behavior, decreased rates of negative attention to misbehavior, reported significantly less distress related to student disruptive behavior, and reported high satisfaction with the training program. Our study supports the growing evidence-base suggesting that TCIT is a promising approach for training teachers in positive behavior management strategies and for improving student disruptive behavior in the classroom.

  20. Approximate algorithms for partitioning and assignment problems

    Science.gov (United States)

    Iqbal, M. A.

    1986-01-01

    The problem of optimally assigning the modules of a parallel/pipelined program over the processors of a multiple computer system under certain restrictions on the interconnection structure of the program as well as the multiple computer system was considered. For a variety of such programs it is possible to find linear time if a partition of the program exists in which the load on any processor is within a certain bound. This method, when combined with a binary search over a finite range, provides an approximate solution to the partitioning problem. The specific problems considered were: a chain structured parallel program over a chain-like computer system, multiple chain-like programs over a host-satellite system, and a tree structured parallel program over a host-satellite system. For a problem with m modules and n processors, the complexity of the algorithm is no worse than O(mnlog(W sub T/epsilon)), where W sub T is the cost of assigning all modules to one processor and epsilon the desired accuracy.

  1. CASA: An Efficient Automated Assignment of Protein Mainchain NMR Data Using an Ordered Tree Search Algorithm

    International Nuclear Information System (INIS)

    Rapid analysis of protein structure, interaction, and dynamics requires fast and automated assignments of 3D protein backbone triple-resonance NMR spectra. We introduce a new depth-first ordered tree search method of automated assignment, CASA, which uses hand-edited peak-pick lists of a flexible number of triple resonance experiments. The computer program was tested on 13 artificially simulated peak lists for proteins up to 723 residues, as well as on the experimental data for four proteins. Under reasonable tolerances, it generated assignments that correspond to the ones reported in the literature within a few minutes of CPU time. The program was also tested on the proteins analyzed by other methods, with both simulated and experimental peaklists, and it could generate good assignments in all relevant cases. The robustness was further tested under various situations

  6. Investigating a computerized scaffolding software for student designed science investigations

    Deters, Kelly M.

    Science standards call for students to develop skills in designing their own investigations. However, this is a complex task that is likely to overload the working memory capacities of students, therefore requiring scaffolding. This study investigated the effects of a computerized scaffold for student-designed experiments. Students (N = 102) used the computer program to individually design an experiment during the third week of their high school general chemistry course. Students were randomly assigned to one of four software versions to determine the effects and interaction effects of backwards-design scaffolding and reflective prompts on laboratory report scores. Scaffolding the students in a backwards-design process lead to significantly higher student performance scores for all students when they were not provided with reflective prompts (p = 0.01). For students labeled as academically advanced by their eighth grade science teacher, backwards design increased student performance scores with or without reflective prompts (p = 0.002). Using reflective prompts had no effect on advanced students. The use of multiple reflective prompts caused the effect of the backwards-design scaffolding to disappear with lower-level students.

    Static Single Assignment (SSA) form is often used as an intermediate representation during code optimization in Java Virtual Machines. Recently, SSA has successfully been used for bytecode verification. However, constructing SSA at the code consumer is costly. SSAbased mobile code transport formats...... have been shown to eliminate this cost by shifting SSA creation to the code producer. These new formats, however, are not backward compatible with the established Java class-file format. We propose a novel approach to transport SSA information implicitly through structural code properties of standard...... Java bytecode. While the resulting bytecode sequence can still be directly executed by traditional Virtual Machines, our novel VM can infer SSA form and confirm its safety with virtually no overhead....

  9. Assignment of uncertainties to scientific data

    International Nuclear Information System (INIS)

    Long-standing problems of uncertainty assignment to scientific data came into a sharp focus in recent years when uncertainty information ('covariance files') had to be added to application-oriented large libraries of evaluated nuclear data such as ENDF and JEF. Question arouse about the best way to express uncertainties, the meaning of statistical and systematic errors, the origin of correlation and construction of covariance matrices, the combination of uncertain data from different sources, the general usefulness of results that are strictly valid only for Gaussian or only for linear statistical models, etc. Conventional statistical theory is often unable to give unambiguous answers, and tends to fail when statistics is bad so that prior information becomes crucial. Modern probability theory, on the other hand, incorporating decision information becomes group-theoretic results, is shown to provide straight and unique answers to such questions, and to deal easily with prior information and small samples.

    This paper presents an algorithm for selecting an appropriate classifier word for a noun. In Thai language, it frequently happens that there is fluctuation in the choice of classifier for a given concrete noun, both from the point of view of the whole spe ech community and individual speakers. Basically, there is no exect rule for classifier selection. As far as we can do in the rule-based approach is to give a default rule to pick up a corresponding classifier of each noun. Registration of classifier for each noun is limited to the type of unit classifier because other types are open due to the meaning of representation. We propose a corpus-based method (Biber, 1993; Nagao, 1993; Smadja, 1993) which generates Noun Classifier Associations (NCA) to overcome the problems in classifier assignment and semantic construction of noun phrase. The NCA is created statistically from a large corpus and recomposed under concept hierarchy constraints and frequency of occurrences.

    2003-09-09

    In many applications of parallel computing, distribution ofthe data unambiguously implies distribution of work among processors. Butthere are exceptions where some tasks can be assigned to one of severalprocessors without altering the total volume of communication. In thispaper, we study the problem of exploiting this flexibility in assignmentof tasks to improve load balance. We first model the problem in terms ofnetwork flow and use combinatorial techniques for its solution. Ourparametric search algorithms use maximum flow algorithms for probing on acandidate optimal solution value. We describe two algorithms to solve theassignment problem with \\logW_T and vbar P vbar probe calls, w here W_Tand vbar P vbar, respectively, denote the total workload and number ofproce ssors. We also define augmenting paths and cuts for this problem,and show that anyalgorithm based on augmenting paths can be used to findan optimal solution for the task assignment problem. We then consideracontinuous version of the problem, and formulate it as a linearlyconstrained optimization problem, i.e., \\min\\|Ax\\|_\\infty,\\; {\\rms.t.}\\;Bx=d. To avoid solving an intractable \\infty-norm optimization problem,we show that in this case minimizing the 2-norm is sufficient to minimizethe \\infty-norm, which reduces the problem to the well-studiedlinearly-constrained least squares problem. The continuous version of theproblem has the advantage of being easily amenable to parallelization.Our experiments with molecular dynamics and overlapped domaindecomposition applications proved the effectiveness of our methods withsignificant improvements in load balance. We also discuss how ourtechniques can be enhanced for heterogeneous systems.

  12. Cluster Chain Based Relay Nodes Assignment

    Full Text Available Wireless sensor Networks are very famous these days due to their coverage and enormous benefits. Clustering the sensor nodes efficiently and dynamically with least energy consumption is the current issue in front of researchers, so that lifetime of sensor nodes will be increased. Cooperation among Relay Nodes and Edge Nodes (ENs along with restrained energy utilization depends upon some protocol such as LEACH for data transmission. In this paper, we propose a Cluster Chain Based Relay Nodes Assignment (CCBRNA scheme to manage the energy constraints in WSN, which Assigns Relay Nodes (Cluster-Heads on the basis of energy and distances parameters but priority is always given to the energy value. The primary model of CCBRNA based on LEACH and PEGASIS protocols is redeveloped to enlarge the lifetime span of network nodes. This scheme is sliced into two main steps. In the first step Cluster-Head is selected and then in second step data transmission starts using an internal chain of nodes according to the distances of nodes from Base Station. In data transmission step, data transportation between different clusters takes place and lastly data is sent to the end terminal moving via the nearest Cluster-Head. Simulation in MATLAB verifies the enhanced lifetime of the nodes. We have used the distance as the key parameter while data transmission takes place. The scheme is efficient as when there are large number of nodes, chaining will take very less time and as well as energy to transmit the data to Cluster-Head. We have further applied an external chaining among Cluster-Heads of different clusters. With the applied limitations and suggested resources such as additional processor, it works well in relaying process.

Dynamic assignment is useful for modeling rush hours in urban areas because temporal spreading of peak hours is increasingly common phenomenon due to shifting the departure earlier or later in time. To model this phenomenon the origin-destination matrix has to be modified through time, which is not possible with static assignment. The assignment in macroscopic model is presented in...

  18. Investigating the relationship between quality, format and delivery of feedback for written assignments in higher education

    DEFF Research Database (Denmark)

    Sopina, Liza Elizaveta; McNeill, Rob

    2015-01-01

    Feedback can have a great impact on student learning. However, in order for it to be effective, feedback needs to be of high quality. Electronic marking has been one of the latest adaptations of technology in teaching and offers a new format of delivering feedback. There is little research investigating the impact the format of feedback has on quality of feedback and subsequently on student learning. This study sets out to investigate the impact paper-based and electronic methods of assignment submission and return have on students’ and markers’ perceived quality of feedback. Students and markers on an undergraduate course were asked to complete an anonymous online survey investigating their perceptions of quality, format and timeliness of feedback delivered electronically and on paper. The results showed that marking and providing feedback electronically was an acceptable method for markers, reporting improved speed and consistency of marking. There was no increase or decrease in satisfaction with the feedback received. Overall, electronic marking was found to be an acceptable method of delivery of feedback on written assignments by both students and markers. The findings of this study suggest that electronic marking can result in more timely feedback for students without impacting on quality.

  4. CAPA (Computer-Assisted Personalized Assignments) in a large university setting

    Pascarella, Andrea M.

    A systematic study of the online homework system CAPA (Computer-Assisted Personalized Assignments) was carried out in the calculus-based introductory physics course at the University of Colorado, Boulder during the fall 2001 semester (N ? 500). This study looked at the effects CAPA had on student learning and attitudes. The students in this class were split into two groups. One group was initially assigned to CAPA; the other group was assigned to traditional homework. At mid-semester the groups switched identities (the students who began the course using CAPA had to complete traditional homework). Exam scores and Force and Motion Concept Evaluation gains showed no statistically significant differences between the groups. Written quizzes and exams were collected from a smaller sample of students and analyzed using a problem-solving rubric. No statistically significant differences in the problem solving abilities of the groups were seen. Student opinions about the effect each homework type had on their learning were elicited. Students with non-expert-like epistemologies felt that CAPA was a better learning tool while students with expert-like epistemologies believed that traditional homework was a better learning tool. Problem solving interviews were conducted weekly with 9 students. From the analysis of this data a problem solving characterization of students using CAPA and traditional homework was inferred. Four types of problems solvers emerged---the CAPA Thinker, Traditional Thinker, CAPA Guesser, and Traditional Guesser. Thinkers tend to have expert-like epistemological beliefs. Guessers generally have non-expert-like epistemologies. On quantitative problems traditional homework promoted metacognitive processes in the Traditional Thinker and CAPA hindered self-evaluation among CAPA Thinkers. On qualitative problems, the opposite was observed to occur. When the students switched homework types at mid-semester it was expected that CAPA Thinkers would become Traditional Thinkers and vice versa. Similar results were expected among Guessers. However, there were students who "switched" from Traditional Thinkers to CAPA Guessers as well as students who "switched" from CAPA Guesser to Traditional Thinker. This may imply that CAPA hinders metacognitive behaviors. Implications for the development of online homework systems are discussed. Directions for future research are suggested.

  5. Electre tri method used to storage location assignment into categories

    Scientific Electronic Library Online (English)

    Marcele Elisa, Fontana; Cristiano Alexandre Virgínio, Cavalcante.

    2013-08-01

    Full Text Available Day after day, the importance of a company having an efficient storage location assignment system increases. Moreover, since products have different warehouse costs and customers' requirements are also different, it is important to sort products in order to adopt strategies for inventory management [...] that are appropriate for each product. However, adopting a policy for each product is not applicable in the real world. Therefore, companies usually categorize products into classes and thereafter adopt specific inventory management policies. Given this situation, this paper puts forward the arguments for adopting a multi-criteria method, Electre TRI, to sort products that both considers criteria relating to the characteristics of a product as to its physical location in the warehouse and the criteria that are important for inventory strategies, such as, for example, the profitability of each unit held in storage.

  6. Mask model calibration for MPC applications utilizing shot dose assignment

    Shrinking feature sizes and the need for tighter CD (Critical Dimension) control require the introduction of new technologies in mask making processes. One of those methods is the dose assignment of individual shots on VSB (Variable Shaped Beam) mask writers to compensate CD non-linearity effects and improve dose edge slope. Using increased dose levels only for most critical features, generally only for the smallest CDs on a mask, the change in mask write time is minimal while the increase in image quality can be significant. However, this technology requires accurate modeling of the mask effects, especially the CD/dose dependencies. This paper describes a mask model calibration flow for Mask Process Correction (MPC) applications with shot dose assignment. The first step in the calibration flow is the selection of appropriate test structures. For this work, a combination of linespace patterns as well as a series of contact patterns are used for calibration. Features sizes vary from 34 nm up to several micrometers in order to capture a wide range of CDs and pattern densities. After mask measurements are completed the results are carefully analyzed and measurements very close to the process window limitation and outliers are removed from the data set. One key finding in this study is that by including patterns exposed at various dose levels the simulated contours of the calibrated model very well match the SEM contours even if the calibration was based entirely on gauge based CD values. In the calibration example shown in this paper, only 1D line and space measurements as well as 1D contact measurements are used for calibration. However, those measurements include patterns exposed at dose levels between 75% and 150% of the nominal dose. The best model achieved in this study uses 2 e-beam kernels and 4 kernels for the simulation of development and etch effects. The model error RMS on a large range of CD down to 34 nm line CD is 0.71 nm. The calibrated model is then used to generate 2D contours for line ends, space ends and contacts and those contours are compared to SEM images. For all patterns, including those very close to the resolution limit, very good contour overlay is achieved. It appears that by including the various dose levels in the calibration a very good separation of the e-beam model components from the etch components is possible and that this also results in very accurate 2D model quality. In conclusion, very accurate mask model calibration is achieved for mask processes using shot dose assignment. Standard test patterns can be used for calibration if they include the dose variations intended for correction.

  7. A Bayesian approach to simultaneously quantify assignments and linguistic uncertainty

    Subject matter expert assessments can include both assignment and linguistic uncertainty. This paper examines assessments containing linguistic uncertainty associated with a qualitative description of a specific state of interest and the assignment uncertainty associated with assigning a qualitative value to that state. A Bayesian approach is examined to simultaneously quantify both assignment and linguistic uncertainty in the posterior probability. The approach is applied to a simplified damage assessment model involving both assignment and linguistic uncertainty. The utility of the approach and the conditions under which the approach is feasible are examined and identified.

  10. Regulatory focus and the assignment of punishment

    Directory of Open Access Journals (Sweden)

    2007-06-01

    Full Text Available Regulatory Focus has been demonstrated to influence human behavior in a number of domains, such as object valuation and readiness to commit time or money to social projects. It has also been demonstrated to influence an individual’s approach to mistakes; and a person’s preference for global or local processing of information. The present work seeks to consider how regulatory focus might interact with punitive behaviors, specifically, the assignment of legal punishment. In this study, 240 undergraduates completed a series of written instruments that assessed their regulatory focus. They read a vignette that described a target that commits a crime, is detected by the police, and is arrested due to a careless mistake. Participants were asked what level of legal punishment they deemed appropriate. Participants’ punitive evaluations show that there are significant interactions a between the regulatory focus of the participant and the regulatory focus of the target and b between the regulatory focus of the participant and the level of detail used to describe the target and her behavior. In each case, when the regulatory foci matched, causing ‘fit,’ the participant was more lenient than in the non-fit condition.

  11. Using student generated blogs to create a global perspective on climate change

    Schuenemann, K. C.

    2012-12-01

    Students in an introductory Global Climate Change college course develop a global perspective on climate change causes, impacts, and mitigation through the use of student generated content in the form of blogging. The students are from diverse backgrounds and mostly non-science majors. They each create a blog for an assigned country. They are immersed in active learning through daily activities that teach them to use numerical data to create and analyze graphs for their blogs. Students are familiarized with other science skills as well, such as how to critically evaluate their sources. This method of using student generated content and active learning encourages students to immerse themselves in the viewpoint of people living in other countries. This creates a tangible understanding of the global stakes of climate change and fosters an emotional involvement in what otherwise might have been an abstract or intimidating topic. The front page of the course blog opens with a world map and a feed from each student's blog. Upon clicking on a country on the world map, the reader is taken to the blog page created by the student in charge of that country. The United States is reserved as a sample page created by the instructor. Throughout the semester, students follow a series of assignments that build their knowledge of the geography, climate, and culture of their assigned country, and these appear as tabs, or informational pages, on their blog. Students are taught to use Excel and they each create temperature and precipitation graphs that compare the climate of a city in their assigned country to that of their home city. Students then write their first blog post on their country's contribution to climate change and how that compares to other countries in the world by importing carbon dioxide emissions data into Excel and creating their own graphs to be used as images in their blog post. The second blog post covers potential climate change impacts on their assigned country such as sea level rise or heat waves. Students then discuss what their country is doing to mitigate climate change, including its role in the Kyoto Protocol and any policies for alternative energy or carbon sequestration. Lastly, students write their final blog post on how their country plans to adapt to climate change. After each blog post, students are required to comment on their classmates' posts. This encourages them to recognize the interdependence of the countries they study, a connection often overlooked in simple paper writing exercises, but made visible through the use of the blogs.

    The Service Academy Research Associates (SARA) program provides an opportunity for Midshipmen and Cadets from US Service Academies to participate in research at Los Alamos National Laboratory (LANL), Lawrence Livermore National Laboratory (LLNL), and Sandia National Laboratory for several weeks during the summer as part of their summer training assignments. During the summer of 2012, three Midshipmen were assigned to work with the XCP Division at LANL for approximately 5-6 weeks. As one of the nation's top national security science laboratories, LANL stretches across 36 square miles, has over 2,100 facilities, and employs over 9,000 individuals including a significant number of students and postdocs. LANL's mission is to 'apply science and technology to: ensure the safety, security, and reliability of the US nuclear deterrent, reduce global threats, and solve other emerging national security challenges.' While LANL officially operates under the US Department of Energy (DoE), fulfilling this mission requires mutual cooperation with the US Department of Defense (DoD) as well. LANL's high concentration of knowledge and experience provides interns a chance to perform research in many disciplines, and its connection with the DoD in both operation and personnel gives SARA students insight to career possibilities both during and after military service. SARA students have plenty of opportunity to enjoy hiking, camping, the Los Alamos YMCA, and many other outdoor activities in New Mexico while staying at the Buffalo Thunder Resort, located 20 miles east of the lab. XCP Division is the Computational Physics division of LANL's Weapons Department. Working with XCP Division requires individuals to be Q cleared by the DoE. This means it is significantly more convenient for SARA students to be assigned to XCP Division than their civilian counterparts as the DoD CNWDI clearance held by SARA students is easily transferred to the lab prior to the students arriving at the start of the summer. SARA students working with XCP Division were given a comprehensive introduction into nuclear engineering and physics, nuclear weapons, and radiation transport and detection via texts and lectures at various classification levels. Students also attended tours of several prominent facilities at LANL including TA-41 Ice House, TA-55 PF-4 plutonium facility, the Nicholas C. Metropolis Center for Modeling and Simulation, also known as the Secure Computing Center (SCC), and the Dual-Axis Radiological Hydro Test (DARHT) facility; in addition, SARA students accompanied by LANL staff traveled to Minot AFB in North Dakota for tours of the 5th Bomb Wing and 91st Missile Wing facilities. Students participated in a week long class on the Monte Carlo N Particle (MCNP) code to supplement their understanding of radiation transport simulations. SARA students were then tasked with using this knowledge to model radiation detectors and use MCNP to compare their models to experimental data and previously accepted models.

  20. Engineering Your Own Superbug: A Useful Assignment to Evaluate Real Learning Comprehension in Microbiology Classes

    Directory of Open Access Journals (Sweden)

    Yun-Chi Chen

    2013-08-01

    Full Text Available The learning comprehension of students in microbiology classes is not easy to evaluate, particularly when the student population is diverse in terms of backgrounds, majors, levels of training and preparedness, and the students’ expectations and enthusiasm for the class. It is difficult to design a one-size-fits-all exam that best suits a mixed student population; and most traditional assignments/case studies focusing on particular microbes or topics might not readily assess students’ overall understanding and learning comprehension. It is important to develop an assessment method that not only can engage students in active learning and deliberate practice but can also promote their imaginative and creative potential. The word “superbugs” often appears in the media and refers to some deadly or drug-resistant microbes. These superbugs possess special phenotypic and functional attributes that constitute their “superness.” It is predicted that more new surprising superbugs will emerge in the future and students should be challenged now with some mindstimulating ideas and exercises in their microbiology class. To develop a supplementary tool to evaluate students’ comprehension and to prepare them for the predicted superbugs unknown to us, a writing project entitled “Constructing Your Own Superbug” was designed to achieve these goals.

  1. Assigning Satisfaction Values to Constraints An Algorithm to Solve Dynamic Meta-Constraints

    CERN Document Server

    Van der Linden, J

    2001-01-01

    The model of Dynamic Meta-Constraints has special activity constraints which can activate other constraints. It also has meta-constraints which range over other constraints. An algorithm is presented in which constraints can be assigned one of five different satisfaction values, which leads to the assignment of domain values to the variables in the CSP. An outline of the model and the algorithm is presented, followed by some initial results for two problems: a simple classic CSP and the Car Configuration Problem. The algorithm is shown to perform few backtracks per solution, but to have overheads in the form of historical records required for the implementation of state.

  2. The implementation of a new method of student assessment in a pathogenic bacteriology laboratory course.

    Science.gov (United States)

    Hite, M F

    2001-05-01

    A new case study method of assessment was developed to challenge advanced undergraduate biology majors interested in medical careers and allied health professions. This method is an alternative to traditional "unknown" identifications used in many microbiology laboratories. Students used various biochemical tests and selective media throughout the course to identify organisms cultured from their own bodies.

  4. The Daycare Assignment : A Dynamic Matching Problem

    Kennes, John; Monte, Daniel

    2014-01-01

    We study the problem of centralized allocation of children to public daycares, illustrated by the case of Denmark. Our framework applies more broadly to problems of dynamic matching in which there is entry and exit of agents over time; for example, it can be used to study the school choice problem once student mobility is taken into account. First, we show that the Gale-Shapley deferred acceptance mechanism adapted to the dynamic problem always yields a stable matching. However, we show that there does not exist any mechanism that is both stable and strategy-proof. We also show that the well-known Top Trading Cycles mechanism is neither Pareto efficient nor strategy-proof. Finally, a mechanism in which parents sequentially choose menus of schools is both strategy-proof and Pareto efficient.

    2009-01-01

    An assignment map is a mathematical operator that describes initial system-environment states for an open quantum systems. We reexamine the notion of assignments, introduced by Pechukas, and show the conditions for which linear assignments can account for correlations between the system and the environment. We study the role of other conditions, such as consistency and positivity of the map, and show the effects of relaxing these. Finally, we establish a connection between the violation of positivity of linear assignments and the no-broadcasting theorem.

  6. A New Secondary Structure Assignment Algorithm Using Cα Backbone Fragments.

    2016-01-01

    The assignment of secondary structure elements in proteins is a key step in the analysis of their structures and functions. We have developed an algorithm, SACF (secondary structure assignment based on Cα fragments), for secondary structure element (SSE) assignment based on the alignment of Cα backbone fragments with central poses derived by clustering known SSE fragments. The assignment algorithm consists of three steps: First, the outlier fragments on known SSEs are detected. Next, the remaining fragments are clustered to obtain the central fragments for each cluster. Finally, the central fragments are used as a template to make assignments. Following a large-scale comparison of 11 secondary structure assignment methods, SACF, KAKSI and PROSS are found to have similar agreement with DSSP, while PCASSO agrees with DSSP best. SACF and PCASSO show preference to reducing residues in N and C cap regions, whereas KAKSI, P-SEA and SEGNO tend to add residues to the terminals when DSSP assignment is taken as standard. Moreover, our algorithm is able to assign subtle helices (310-helix, π-helix and left-handed helix) and make uniform assignments, as well as to detect rare SSEs in β-sheets or long helices as outlier fragments from other programs. The structural uniformity should be useful for protein structure classification and prediction, while outlier fragments underlie the structure-function relationship. PMID:26978354

  11. Automated sequence-specific protein NMR assignment using the memetic algorithm MATCH

    International Nuclear Information System (INIS)

    MATCH (Memetic Algorithm and Combinatorial Optimization Heuristics) is a new memetic algorithm for automated sequence-specific polypeptide backbone NMR assignment of proteins. MATCH employs local optimization for tracing partial sequence-specific assignments within a global, population-based search environment, where the simultaneous application of local and global optimization heuristics guarantees high efficiency and robustness. MATCH thus makes combined use of the two predominant concepts in use for automated NMR assignment of proteins. Dynamic transition and inherent mutation are new techniques that enable automatic adaptation to variable quality of the experimental input data. The concept of dynamic transition is incorporated in all major building blocks of the algorithm, where it enables switching between local and global optimization heuristics at any time during the assignment process. Inherent mutation restricts the intrinsically required randomness of the evolutionary algorithm to those regions of the conformation space that are compatible with the experimental input data. Using intact and artificially deteriorated APSY-NMR input data of proteins, MATCH performed sequence-specific resonance assignment with high efficiency and robustness

  12. Highly automated protein backbone resonance assignment within a few hours: the strategy and software package

    International Nuclear Information System (INIS)

    Sequential resonance assignment represents an essential step towards the investigation of protein structure, dynamics, and interaction surfaces. Although the experimental sensitivity has significantly increased in recent years, with the availability of high field magnets and cryogenically cooled probes, resonance assignment, even of small globular proteins, still generally requires several days of data collection and analysis using standard protocols. Here we introduce the BATCH strategy for fast and highly automated backbone resonance assignment of 13C, 15N-labelled proteins. BATCH makes use of the fast data acquisition and analysis tools BEST, ASCOM, COBRA, and HADAMAC, recently developed in our laboratory. An improved Hadamard encoding scheme, presented here, further increases the performance of the HADAMAC experiment. A new software platform, interfaced to the NMRView software package, has been developed that enables highly automated NMR data processing and analysis, sequential resonance assignment, and 13C chemical shift extraction. We demonstrate for four small globular proteins that sequential resonance assignment can be routinely obtained within a few hours, or less, in a highly automated and robust way

  14. CAMRA: Chemical shift based computer aided protein NMR assignments

    International Nuclear Information System (INIS)

    A suite of programs called CAMRA (Computer Aided Magnetic Resonance Assignment) has been developed for computer assisted residue-specific assignments of proteins. CAMRA consists of three units: ORB, CAPTURE and PROCESS. ORB predicts NMR chemical shifts for unassigned proteins using a chemical shift database of previously assigned homologous proteins supplemented by a statistically derived chemical shift database in which the shifts are categorized according to their residue, atom and secondary structure type. CAPTURE generates a list of valid peaks from NMR spectra by filtering out noise peaks and other artifacts and then separating the derived peak list into distinct spin systems. PROCESS combines the chemical shift predictions from ORB with the spin systems identified by CAPTURE to obtain residue specific assignments. PROCESS ranks the top choices for an assignment along with scores and confidence values. In contrast to other auto-assignment programs, CAMRA does not use any connectivity information but instead is based solely on matching predicted shifts with observed spin systems. As such, CAMRA represents a new and unique approach for the assignment of protein NMR spectra. CAMRA will be particularly useful in conjunction with other assignment methods and under special circumstances, such as the assignment of flexible regions in proteins where sufficient NOE information is generally not available. CAMRA was tested on two medium-sized proteins belonging to the chemokine family. It was found to be effective in predicting the assignment providing a database of previously assigned proteins with at least 30% sequence identity is available. CAMRA is versatile and can be used to include and evaluate heteronuclear and three-dimensional experiments

  15. A big picture look at big coal: Teaching students to link societal and environmental issues

    Science.gov (United States)

    Sojka, S. L.

    2014-12-01

    The environmental impact of coal mining and burning of coal is evident and generally easy to understand. However, students often struggle to understand the social impacts of coal mining. A jigsaw activity culminating in a mock town hall meeting helps students link social, economic and environmental impacts of coal mining. Students are divided into four groups and assigned the task of researching the environmental, social, economic or health impacts of coal mining in West Virginia. When students have completed the research, they are assigned a role for the town hall. Roles include local community members, direct employees of the coal industry, business owners from industries related to coal mining, and environmentalists. One student from each research area is assigned to each role, forcing students to consider environmental, social, health and economic aspects of coal mining in choosing an appropriate position for their role. Students have 30 minutes to prepare their positions and then present for 2-5 minutes in the simulated town hall. We then have open class discussion and review the positions. Finally, students are required to write a letter to the editor of the local paper. The specific topic for the town hall and letters can be varied based on current events and could include new regulations on power plants, mine safety, government funding of alternative energy supplies or a range of other topics. This approach forces students to consider all aspects of the issue. In addition, because students have to assume a role, they are more aware of the direct impact that coal mining has on individuals' lives.

  17. PACES: Protein sequential assignment by computer-assisted exhaustive search

    International Nuclear Information System (INIS)

    A crucial step in determining solution structures of proteins using nuclear magnetic resonance (NMR) spectroscopy is the process of sequential assignment, which correlates backbone resonances to corresponding residues in the primary sequence of a protein, today, typically using data from triple-resonance NMR experiments. Although the development of automated approaches for sequential assignment has greatly facilitated this process, the performance of these programs is usually less satisfactory for large proteins, especially in the cases of missing connectivity or severe chemical shift degeneracy. Here, we report the development of a novel computer-assisted method for sequential assignment, using an algorithm that conducts an exhaustive search of all spin systems both for establishing sequential connectivities and then for assignment. By running the program iteratively with user intervention after each cycle, ambiguities in the assignments can be eliminated efficiently and backbone resonances can be assigned rapidly. The efficiency and robustness of this approach have been tested with 27 proteins of sizes varying from 76 amino acids to 723 amino acids, and with data of varying qualities, using experimental data for three proteins, and published assignments modified with simulated noise for the other 24. The complexity of sequential assignment with regard to the size of the protein, the completeness of NMR data sets, and the uncertainty in resonance positions has been examined

    Full Text Available After a laborious and extravagant procedure the drug finally enters the market for use. But who determines the new drug status as a prescription only or an OTC? There is a clear cut contrast between the US and India with respect to their assignment guidelines and the future prospect of a new drug. In the US the regulatory status of the approved drug is determined as per the FDA guidelines (FDCA of 1938 in accordance with the Durham-Humphrey act of 1951 which depicts the criteria required for a pharmaceutical product to be marketed as a prescription drug or an OTC product. CDSCO headed by the DCGI is the authority responsible for determining the regulatory status which acts as per the regulations listed in Drugs and Cosmetics Act of 1940 in India. The US regulatory system stipulates the malleability for the inter conversion of the drugs regulatory status known as “Rx to OTC switch” which is deficient in India. Perfect implementation of regulations in India will promote effective use of OTC’s and forestall illicit sale of prescription drugs as OTC’s.

  6. Art for the Smart: Paper and oral presentation assignments for an Earth Materials course

    Science.gov (United States)

    Wetzel, L. R.

    2011-12-01

    A letter from the fictional Art for the Smart company addresses students in the Earth Materials course: "You might be wondering why an artist needs a geology consultant. I am creating a sculpture garden filled with mythical beings. I would like each student to recommend two unique minerals for one of these sculptures..." For this project students randomly select a mythical being, two mineral groups, and a mineral characteristic. For example, a student might be assigned the goddess Freya, a sulfate, a vanadate, and twinning. Students then choose a specific mineral from each group, describe their physical and chemical characteristics, and recommend how the minerals could be incorporated into the sculpture. Reports are presented in short oral presentations and two-page business letters with accompanying bibliography and illustrations. The letter format provides a concise way to communicate results to the Art for the Smart "client" while preparing students for their job-hunting days ahead. The oral presentations are structured as features for a news program. Talks are limited to three to five minutes and four slides: title page, mineral #1, mineral #2, and mythical being. The strict limits help students concentrate on scientific content and smooth delivery rather than flashy visual aids. The student audience and the professor evaluate each in-class presentation. This has become a popular assignment because it engages student imaginations to relate minerals to mythical beings and creatively design a sculpture. Each project is unique and therefore more interesting for both students and faculty to evaluate. The projects are nearly impossible to plagiarize from previous years or from internet sources. Earth Materials is a sophomore level course for Geoscience and Marine Science majors at Eckerd College. The Art for the Smart project leads into an assignment for the second half of the semester featuring building stones. A new "client" sends a letter to the class explaining the situation: "I own a building in downtown St. Petersburg adorned with natural building stone. I am planning to expand my business to your hometown. I would like your professional opinion on whether or not I should use the same stone on my new building..." In this case, students examine thin sections and hand specimens to identify building stones. Each student chooses one building stone and conducts literature research to explain the advantages and disadvantages of using the rock on a building. The ultimate goal is not only to describe the rock and its geologic origins, but also to persuade the "client" to use or not use the building stone in a new location. In addition to writing a business letter and giving an in-class presentation, students give a short talk in the "field" at the downtown location featuring the building stone. In completing the two Earth Materials projects over the course of the semester, students progress from recognizing minerals in hand specimens to identifying rocks using thin sections and developing theories regarding their geologic origins.

  7. Graphical interpretation of Boolean operators for protein NMR assignments

    International Nuclear Information System (INIS)

    We have developed a graphics based algorithm for semi-automated protein NMR assignments. Using the basic sequential triple resonance assignment strategy, the method is inspired by the Boolean operators as it applies 'AND'-, 'OR'- and 'NOT'-like operations on planes pulled out of the classical three-dimensional spectra to obtain its functionality. The method's strength lies in the continuous graphical presentation of the spectra, allowing both a semi-automatic peaklist construction and sequential assignment. We demonstrate here its general use for the case of a folded protein with a well-dispersed spectrum, but equally for a natively unfolded protein where spectral resolution is minimal

  8. An Enhanced Client-Server Assignment for Internet Distributed Systems

    Directory of Open Access Journals (Sweden)

    2014-04-01

    Full Text Available Internet is a collection of several distributed systems consisting of various clients and servers. These clients communicate with each other with the help of intermediate servers. An optimized performance for such a system needs proper client-server assignment. Such a system can be achieved by mainly considering the factors like total communication load and load balancing of the servers. We propose an approach based on an algorithm which obtain an approximately optimal solution for the client-server assignment problem. The simulation experiments will show that our approach has better efficiency than the existing client-server assignment.

  9. Computational Hardness of Enumerating Satisfying Spin-Assignments in Triangulations

    CERN Document Server

    Jiménez, Andrea

    2011-01-01

    Satisfying spin-assignments in triangulations of a surface are states of minimum energy of the antiferromagnetic Ising model on triangulations which correspond (via geometric duality) to perfect matchings in cubic bridgeless graphs. In this work we show that it is NP-complete to decide whether or not a surface triangulation admits a satisfying spin-assignment, and that it is #P-complete to determine the number of such assignments. Both results are derived via an elaborate (and atypical) reduction that maps a Boolean formula in 3-conjunctive normal form into a triangulation of an orientable closed surface.

  10. RDC derived protein backbone resonance assignment using fragment assembly

    International Nuclear Information System (INIS)

    Experimental residual dipolar couplings (RDCs) in combination with structural models have the potential for accelerating the protein backbone resonance assignment process because RDCs can be measured accurately and interpreted quantitatively. However, this application has been limited due to the need for very high-resolution structural templates. Here, we introduce a new approach to resonance assignment based on optimal agreement between the experimental and calculated RDCs from a structural template that contains all assignable residues. To overcome the inherent computational complexity of such a global search, we have adopted an efficient two-stage search algorithm and included connectivity data from conventional assignment experiments. In the first stage, a list of strings of resonances (CA-links) is generated via exhaustive searches for short segments of sequentially connected residues in a protein (local templates), and then ranked by the agreement of the experimental 13C? chemical shifts and 15N-1H RDCs to the predicted values for each local template. In the second stage, the top CA-links for different local templates in stage I are combinatorially connected to produce CA-links for all assignable residues. The resulting CA-links are ranked for resonance assignment according to their measured RDCs and predicted values from a tertiary structure. Since the final RDC ranking of CA-links includes all assignable residues and the assignment is derived from a “global minimum”, our approach is far less reliant on the quality of experimental data and structural templates. The present approach is validated with the assignments of several proteins, including a 42 kDa maltose binding protein (MBP) using RDCs and structural templates of varying quality. Since backbone resonance assignment is an essential first step for most of biomolecular NMR applications and is often a bottleneck for large systems, we expect that this new approach will improve the efficiency of the assignment process for small and medium size proteins and will extend the size limits assignable by current methods for proteins with structural models.

    Full Text Available Information and communications technologies today are used in virtually any university course when students prepare their papers. ICT is also needed after people are graduated from university and enter the job market. This author is an instructor in the field of informatics related to health care and social sciences at the Riga Stradins University. In practice, he has found that after completing informatics courses (IC at the university level, students and practicing specialists at various levels find it hard to decide on what data processing method to use in order to interpret extracted results in the relevant area of specialisation. There are various data processing methods in the literature, presented individually and without adequate linkages. The author has found in practice that when such assignments are handled, there is closer linkage among data processing methods than the literature would suggest. In this article, the authors deal with the following issues: (1 how assignments given during informatics courses at the university level can be integrated with the relevant area of specialisation by making use of professional standards, guidebooks to studies in other courses, descriptions and scholarly publications so as to help students and practicing specialists to take decisions on data processing methods, their use, and the interpretation of their results; (2 how to ensure that educational data related to the area of specialisation are obtained on the basis of statistics in scholarly publications; (3 what kind of content is to be used for students of health care and the social sciences; (4 how to choose methods to resolve data processing issues; (5 what are the recommended principles for evaluating the knowledge, skills and talents of students? The views that are presented in this paper are those of the authors or of other authors.

  1. The Design of ADAT: A Tool for Assessing Automata-Based Assignments

    Directory of Open Access Journals (Sweden)

    Zarina Shukur

    2008-01-01

    Full Text Available This study describes the design of an automatic assessment system for assessing an automata-based assignment. Automata concept is taught in several undergraduate computing courses such as Theory of Computation, Automata and Formal Languages and Compilers. We take two elements into consideration when assessing the student's answers; static element and dynamic element. The static element involves the number of states (initial and final as well and the number of transitions. Whilst the dynamic aspect involves executing the automata against several test data. In this work, we rely heavily on the JFLAP for drawing and executing the automata.

  19. The effects of interactive (TIPS) homework on family involvement and science achievement of middle grade students

    Science.gov (United States)

    van Voorhis, Frances Landis

    The purpose of the study was to investigate the effects of interactive and non-interactive science homework assignments on family involvement in homework, homework completion and accuracy, student science achievement, and student and parent attitudes about science. Most previous research on homework has examined what parental involvement results naturally, without prompts or instruction from teachers. In contrast, this study experimentally examined the effects of teacher prompts to parents for involvement in their children's homework. Two hundred and fifty-three students from 10 classes of sixth and eighth grade students participated in the study that lasted 18 weeks of the school year. Six classes of students completed the TIPS (Teachers Involve Parents In Schoolwork) interactive homework assignments, and four classes completed the non-interactive assignments that contained the same content and questions as the TIPS assignments. TIPS students received instructions to involve a parent or other family partner in certain sections of the homework assignment. ATIPS students received the same assignment with no instruction to involve another person. Results indicated that TIPS students more often involved parents in their science homework assignments than ATIPS students. However, TIPS science students reported no more parental involvement in homework than ATIPS students in subjects not assigning interactive homework. Therefore, the TIPS instructions elicited more parental involvement in homework than the ATIPS assignments. TIPS students did not differ from ATIPS students in the percent of homework returned or accuracy. Students who rated the homework more positively and involved families regularly returned more homework assignments than students who did not do so. TIPS students did earn significantly higher science report card grades than ATIPS students after controlling for background variables, teacher effects, and percent of homework returned. Exploratory analyses of matched student and parent data suggest the importance of both student and parent data in research of interactive homework. The results of the study indicate the benefits of well-designed interactive homework for levels of family involvement, science attitudes, and science achievement.

  20. Partial eigenvalue assignment and its stability in a time delayed system

    Science.gov (United States)

    Singh, Kumar V.; Dey, Rajeeb; Datta, Biswa N.

    2014-01-01

    Active vibration control strategy is an effective way to control dangerous vibrations in a structure, caused by resonance and to manipulate the dynamics of vibrational response. Implementation of this strategy requires real-time computations of two feedback control matrices such that a small amount of eigenvalues of the associated quadratic matrix pencil are replaced by suitably chosen ones while the remaining large number of eigenvalues and eigenvectors remain unchanged ensuring the no spill-over. This mathematical problem is referred to as the Quadratic Partial Eigenvalue Assignment problem. The greatest challenge there is to solve the problems using the knowledge of only a small number of eigenvalues and eigenvectors that are computable using state-of-the-art techniques. This paper generalizes the earlier work on partial assignment to constant time-delay systems. Furthermore, a posterior stability analysis is carried out to identify the ranges of the time-delay that maintains the closed-loop assignment while keeping the stability of the infinite number of eigenvalues for the time-delayed systems. The practical features of the proposed methods are that it is implemented in the second-order setting itself using only those small number of eigenvalues and the eigenvectors that are to be assigned and the no spill-over is established by means of mathematical results. The results of our numerical experiments support the validity of our proposed methods.

  1. Automated protein backbone assignment using the projection-decomposition approach

    Spectral projection experiments by NMR in conjunction with decomposition analysis have been previously introduced for the backbone assignment of proteins; various pulse sequences as well as the behaviour with low signal-to-noise or chemical shift degeneracy have been illustrated. As a guide for routine applications of this combined tool, we provide here a systematic analysis on different types of proteins using welldefined run-time parameters. As a second result of this study, the backbone assignment module SHABBA was extensively rewritten and improved. Calculations on ubiquitin yielded again fully correct and nearly complete backbone and CH{beta} assignments. For the 128 residue long azurin, missing assignments mostly affect H{alpha} and H{beta}. Among the remaining backbone (plus C{beta}) nuclei 97.5% could be assigned with 1.0% differences to a reference. Finally, the new SHABBA algorithm was applied to projections recorded for a yeast histone protein domain at room temperature, where the protein is subject to partial unfolding: this leads to unobservable resonances (about a dozen missing signals in a normal 15N-HSQC) and extensive degeneracy among the resonances. From the clearly observable residues, 97.5% of the backbone and CH{beta}resonances could be assigned, of which only 0.8 % showed differences to published shifts. An additional study on the protein MMP20, which exhibits spectral difficulties to an even larger extent, explores the limitations of the approach.

  2. An automated method for consistent helix assignment using turn information.

    Science.gov (United States)

    Koch, Oliver; Cole, Jason

    2011-05-01

    A new automated helix assignment method is presented that leads to a more consistent definition of the helix termini, especially of the helix C-terminus. The method assigns a helix to segments of protein chain where adjacent helical turn structures are observed, capped by specific distorted turn types (e.g., open helical turns without a hydrogen bond) or capping motifs (e.g., the Schellman motif). Helix termini are detected by observing the behavior of the NH group in N-termini and the CO group in C-termini; in each case, the respective group must be free to interact with hydrogen bonding partners outside of the putative helix for a helix terminus to be assigned. The presented assignment method and SHAFT-assigned helices are part of Secbase and are made available with Relibase+ 3.0 and the free web version of Relibase 3.0. The method can also be used for the helix assignments of additional protein structures. PMID:21365674

  6. Neptune's Discovery: Le Verrier, Adams, and the Assignment of Credit

    Science.gov (United States)

    Sheehan, William

    2011-01-01

    As one of the most significant achievements of 19th century astronomy, the discovery of Neptune has been the subject of a vast literature. A large part of this literature--beginning with the period immediately after the optical discovery in Berlin--has been the obsession with assigning credit to the two men who attempted to calculate the planet's position (and initially this played out against the international rivalry between France and England). Le Verrier and Adams occupied much different positions in the Scientific Establishments of their respective countries; had markedly different personalities; and approached the investigation using different methods. A psychiatrist and historian of astronomy tries to provide some new contexts to the familiar story of the discovery of Neptune, and argues that the personalities of these two men played crucial roles in their approaches to the problem they set themselves and the way others reacted to their stimuli. Adams had features of high-functioning autism, while Le Verrier's domineering, obsessive, orderly personality--though it allowed him to be immensely productive--eventually led to serious difficulties with his peers (and an outright revolt). Though it took extraordinary smarts to calculate the position of Neptune, the discovery required social skills that these men lacked--and thus the process to discovery was more bumbling and adventitious than it might have been. The discovery of Neptune occurred at a moment when astronomy was changing from that of heroic individuals to team collaborations involving multiple experts, and remains an object lesson in the sociological aspects of scientific endeavor.

    2014-10-01

    We discuss our implementation of targeted pre-reading assignments with an associated online quiz in two science classes, one physics and one biology. Our goal was to create a pre-class assignment that helped students recognize the benefits of reading before class. Students were asked to take part in a survey about how and why they completed the pre-reading assignments. We found that 80% of students read the textbook on a regular basis, which is much higher than reported in previous studies. Also nearly 3/4 of students reported using productive strategies for completing the reading assignment and cited reading prior to class as being helpful to their learning. Student self-reports were checked against electronic logs and were found to be highly accurate. Moreover, these results were nearly identical between the physics and biology courses.

  14. A multiobjective approach towards weapon assignment in a ground-based air defence environment

    Directory of Open Access Journals (Sweden)

    DP Lötter

    2013-06-01

    Full Text Available A typical ground-based air defence (GBAD environment comprises defended assets on the ground which require protection from enemy aircraft entering the defended airspace. Protection against these aircraft is afforded by means of pre-deployed ground-based weapon systems that are assigned to engage these enemy aircraft according to some pre-specified criterion or set of criteria. The conditions under which human operators have to propose assignments of weapon systems to engage these aircraft are severely stressful since time is a critical factor and there is no room for error. Some progress has already been made with respect to the design of computerised threat evaluation and weapon assignment (TEWA decision support systems (DSSs within the context of a GBAD system. However, the weapon assignment (WA component within such a TEWA DSS is typically based on a single criterion (objective. The aim in this paper is to model the WA problem as a multiobjective decision problem. A list of relevant factors (related to objectives is identified by means of feedback received from a WA questionnaire which was completed by a number of military experts. For illustrative purposes, two objectives, namely the cost of assigning weapon systems for engagement and the accumulated survival probabilities of observed threats as a result of these engagements, were isolated from these factors in order to derive a bi-objective WA model. This model is solved in the context of a simulated, but realistic, GBAD environment by means of an existing multiobjective solution technique called the Nondominated Sorting Genetic Algorithm II.

    Full Text Available This research examines the effect of a Facebook game (Pearl Peril that requires English vocabulary knowledge on students’ English vocabulary development. The participants of the study include 7th year students in a private middle school in Turkey. Of the experimental models, this study uses a pretest-posttest control group model. Initially, a vocabulary test that was developed by the researchers was conducted on 81 middle school students in Edirne for analyzing validity and reliability. Subsequently, this test was applied as a pretest to both control and experiment groups. Following the application of the pretest, students in the experiment group were required to play Pearl Peril for one month. In the course of this one month, the words in Pearl Peril were taught to control group in regular classes as a part of the syllabus. At the end of this procedure, the vocabulary test that was used as a pretest was administered to both groups this time as a posttest. The study results show a significant difference between the test scores of the control and experiment groups. Thus, the current study is important in terms of exemplifying how to benefit from various social media applications in educational practices.

  16. Constrained Task Assignment and Scheduling On Networks of Arbitrary Topology

    Science.gov (United States)

    Jackson, Justin Patrick

    This dissertation develops a framework to address centralized and distributed constrained task assignment and task scheduling problems. This framework is used to prove properties of these problems that can be exploited, develop effective solution algorithms, and to prove important properties such as correctness, completeness and optimality. The centralized task assignment and task scheduling problem treated here is expressed as a vehicle routing problem with the goal of optimizing mission time subject to mission constraints on task precedence and agent capability. The algorithm developed to solve this problem is able to coordinate vehicle (agent) timing for task completion. This class of problems is NP-hard and analytical guarantees on solution quality are often unavailable. This dissertation develops a technique for determining solution quality that can be used on a large class of problems and does not rely on traditional analytical guarantees. For distributed problems several agents must communicate to collectively solve a distributed task assignment and task scheduling problem. The distributed task assignment and task scheduling algorithms developed here allow for the optimization of constrained military missions in situations where the communication network may be incomplete and only locally known. Two problems are developed. The distributed task assignment problem incorporates communication constraints that must be satisfied; this is the Communication-Constrained Distributed Assignment Problem. A novel distributed assignment algorithm, the Stochastic Bidding Algorithm, solves this problem. The algorithm is correct, probabilistically complete, and has linear average-case time complexity. The distributed task scheduling problem addressed here is to minimize mission time subject to arbitrary predicate mission constraints; this is the Minimum-time Arbitrarily-constrained Distributed Scheduling Problem. The Optimal Distributed Non-sequential Backtracking Algorithm solves this problem. The algorithm is correct, complete, outputs time optimal schedules, and has low average-case time complexity. Separation of the task assignment and task scheduling problems is exploited here to ameliorate the effects of an incomplete communication network. The mission-modeling conditions that allow this and the benefits gained are discussed in detail. It is shown that the distributed task assignment and task scheduling algorithms developed here can operate concurrently and maintain their correctness, completeness, and optimality properties.

    2015-09-01

    Wildlife forensic science has become a key means of enforcing legislation surrounding the illegal trade in protected and endangered species. A relatively new dimension to this area of forensic science is to determine the geographic origin of a seized sample. This review focuses on DNA testing, which relies on assignment of an unknown sample to its genetic population of origin. Key examples of this are the trade in timber, fish and ivory and these are used only to illustrate the large number of species for which this type of testing is potentially available. The role of mitochondrial and nuclear DNA markers is discussed, alongside a comparison of neutral markers with those exhibiting signatures of selection, which potentially offer much higher levels of assignment power to address specific questions. A review of assignment tests is presented along with detailed methods for evaluating error rates and considerations for marker selection. The availability and quality of reference data are of paramount importance to support assignment applications and ensure reliability of any conclusions drawn. The genetic methods discussed have been developed initially as investigative tools but comment is made regarding their use in courts. The potential to compliment DNA markers with elemental assays for greater assignment power is considered and finally recommendations are made for the future of this type of testing. PMID:25795277

  19. Traffic assignment models in large-scale applications

    DEFF Research Database (Denmark)

    Rasmussen, Thomas Kjær

    2015-01-01

    Transport models are becoming more and more disaggregate to facilitate a realistic representation of individuals and their travel patterns. In line with this development, the PhD study focuses on facilitating the deployment of traffic assignment models in fully disaggregate activity-based model frameworks. In the correct integration, such frameworks allow realistic representation of individual-specific household interactions, time-space constraints and preference structures. Individual trips can also be evaluated on a detailed address-to-address level and aggregation biases are avoided. The study focuses on large-scale applications and contributes with methods to actualise the true potential of disaggregate models. To achieve this target, contributions are given to several components of traffic assignment modelling, by (i) enabling the utilisation of the increasingly available data sources on individual behaviour in the model specification, (ii) proposing a method to use disaggregate Revealed Preference (RP) data to estimate utility functions and provide evidence on the value of congestion and the value of reliability, (iii) providing a method to account for individual mis-perceptions in the choice set generation for complex multi-modal networks, and (iv) addressing the difficulty of choice set generation by making available a theoretical framework, and corresponding operational solution methods, which consistently distinguishes between used and unused paths. The availability of data is essential in the development and validation of realistic models for large-scale applications. Nowadays, modern technology facilitates easy access to RP data and allows large-scale surveys. The resulting datasets are, however, usually very large and hence data processing is necessary to extract the pieces of information relevant to the analysis at hand. Manual processing of the datasets are typically not possible, and it is therefore necessary to have methods available which in some automated ways clean and prepare the datasets forthe desired use. The present study proposes a fully automatic post-processing procedure that combines fuzzy logic- and GIS-based methods to process raw individual-based GPS data with no additional information required from the respondent. The method categorises trips and trip legs and associates the trip legs with the most probable mode of transport used. The method was validated through the application to a dataset consisting of raw individualbased GPS logs collected among 183 respondents living in the Greater Copenhagen area. Through the use of a control-questionnaire, the study found that the proposed method (i) vi identified corresponding trip legs for 82% of the reported trip legs, (ii) avoided classifying nontrips such as scatter around activities as trip legs, and (iii) identified the correct mode of transport for more than 90% of the trip legs. These results are very promising, especially when compared to results generated by existing algorithms. The results highlight the potential of the method proposed and the possibility to use individual-based GPS units for travel surveys in real-life large-scale multi-modal networks. Congestion is known to highly influence the way we act in the transportation network (and organise our lives), because of longer travel times, but the reliability of the travel time also has a large impact on our travel choices. Consequently, in order to improve the realism of transport models, correct understanding and representation of two values that are related to the value of time (VoT) are essential: (i) the value of congestion (VoC), as the VoT varies with traffic conditions and hence congestion multipliers reflect the complexity of driving conditions when more vehicles are present on the road, and (ii) the value of reliability (VoR), as the VoT relates to the predictability of travel time and the repeatability of the travel experience. Congestion and reliability highly influence each other, but so far only studies based on Stated Preference (SP) data considered concurrently conge

  20. Media Articles Describing Advances in Scientific Research as a Vehicle for Student Engagement Fostering Climate Literacy

    "Records of Global Climate Change" enables students to fulfill the science component of an undergraduate distribution requirement in "Critical Approaches" at IU Bloomington. The course draws students from all disciplines with varying levels of understanding of scientific approaches and often limited familiarity with climate issues. Its discussion sessions seek to foster scientific literacy via an alternating series of assignments focused on a combination of exercises that involve either examination and interpretation of on-line climate data or consideration and assessment of the scientific basis of new discoveries about climate change contained in recently published media articles. The final assignment linked to the discussion sessions requires students to review and summarize the topics discussed during the semester. Their answers provide direct evidence of newly acquired abilities to assimilate and evaluate scientific information on a range of topics related to climate change. In addition, student responses to an end-of-semester survey confirm that the vast majority considers that their knowledge and understanding of climate change was enhanced, and unsolicited comments note that the discussion sessions contributed greatly to this advancement. Many students remarked that the course's emphasis on examination of paleoclimate records helped their comprehension of the unprecedented nature of present-day climate trends. Others reported that their views on the significance of climate change had been transformed, and some commented that they now felt well equipped to engage in discussions about climate change because they were better informed about its scientific basis and facts.

    Huang, Yi Ting; Zheng, Xiaobei; Meng, Xiangzhi; Snedeker, Jesse

    2013-11-01

    Children's difficulty understanding passives in English has been attributed to the syntactic complexity, overall frequency, cue reliability, and/or incremental processing of this construction. To understand the role of these factors, we used the visual-world paradigm to examine comprehension in Mandarin Chinese where passives are infrequent but signaled by a highly valid marker (BEI). Eye-movements during sentences indicated that these markers triggered incremental role assignments in adults and 5-year-olds. Actions after sentences indicated that passives were often misinterpreted as actives when markers appeared after the referential noun ("Seal BEI it eat" ? The seal is eaten by it). However, they were more likely to be interpreted correctly when markers appeared before ("It BEI seal eat" ? It is eaten by the seal). The actions and the eye-movements suggest that for both adults and children, interpretations of passive are easier when they do not require revision of an earlier role assignment. PMID:24376303

  5. Multicast routing and wavelength assignment in WDM networks: a bin packing approach

    Science.gov (United States)

    Skorin-Kapov, Nina

    2006-04-01

    We address the problem of multicast routing and wavelength assignment (MClowbarRWA) in wavelength-routed WDM optical networks. Multicast requests are facilitated in WDM networks by setting up so-called light trees and assigning wavelengths to them. Objectives of the MClowbarRWA problem include minimizing the number of distinct wavelengths used to establish a set of multicast requests and minimizing the cost of the corresponding light trees. This cost can represent the physical length, delay, or actual cost of a tree. Applications that require quality of service (QoS) multicasting can impose additional constraints on light trees, such as a bounded end-to-end delay. Proposed are heuristic algorithms based on bin packing methods for the general MClowbarRWA problem, which is NP complete. These algorithms can consider unicast, multicast, and broadcast requests with or without QoS demands. Computational tests indicate that these algorithms are efficient, particularly for dense networks.

  6. GPU-based SoftAssign for Maximizing Image Utilization in Photomosaics

    Directory of Open Access Journals (Sweden)

    2011-07-01

    Full Text Available Photomosaic generation is a popular non-photorealistic rendering technique, where a single image is assembled from several smaller ones. Visual responses change depending on the proximity to the photomosaic, leading to many creative prospects for publicity and art. Synthesizing photomosaics typically requires very large image databases in order to produce pleasing results. Moreover, repetitions are allowed to occur which may locally bias the mosaic. This paper provides alternatives to prevent repetitions while still being robust enough to work with coarse image subsets. Three approaches were considered for the matching stage of photomosaics: a greedy-based procedural algorithm, simulated annealing and SoftAssign. It was found that the latter delivers adequate arrangements in cases where only a restricted number of images is available. This paper introduces a novel GPU-accelerated SoftAssign implementation that outperforms an optimized CPU implementation by a factor of 60 times in the tested hardware.

    2016-02-01

    A novel method for partial eigenstructure assignment of undamped vibration systems using acceleration and displacement output feedback is presented in this paper. It is based on modifications of mass and stiffness that preserve partial eigenstructure. A numerical algorithm for determining the required control gain matrices of acceleration and displacement output feedback, which assign the desired eigenstructure, is developed. This algorithm is easy to implement, and works directly on the second-order system model. More importantly, the algorithm allows the output matrix and the input matrix to be specified beforehand and also leads naturally to a small norm solution of the gain matrices. Finally, some numerical results are presented to demonstrate the effectiveness and accuracy of the proposed algorithm.

    2007-12-01

    The relation between electrical circuit and traffic network has been proposed by Sasaki and Inouye, but they proposed link cost function is a linear function which cannot present the congestion situation. Cho and Huang extended the link cost function to a nonlinear function which can explain the congested network. In this paper, we proposed a foremost and novel approach to solve the traffic assignment problem (TAP) by simulating the electrical circuit network which consists of nonlinear link cost function models. Comparing with the solutions of Frank-Wolfe algorithm, the simulation results are nearly identical. Thus, the simulation of a network circuit model can be applied to solve network traffic assignment problems. Finally, two examples are proposed, and the results confirmed that electrical circuit simulation is workable in solving congested network traffic assignment problems.

  9. Optimal assignment of incoming flights to baggage carousels at airports

    DEFF Research Database (Denmark)

    Barth, Torben C.

    2013-01-01

    The problem considered in this report is an assignment problem occurring at airports. This problem concerns the assignment of baggage carousels in baggage claim halls to arriving aircraft (baggage carousel assignment problem). This is a highly dynamic problem since disruptions frequently occur during operations. We introduce a basic static model that can be adapted to the layout of different airports. Afterwards we show how a decision support system based on a MIP-model can be designed in a dynamic real world environment. The system supports the decisions of the dispatcher during daily operations. Computational results for a real world problem at Frankfurt Airport are presented. At Frankfurt Airport the suggested solution method was successfully implemented and is running now for over half an year. The experiences show that the system increases the quality of the dispatching process and in general is a substantial support in decision making.

    2013-05-01

    Full Text Available In this paper, we consider a problem of network design of personal communication services (PCS. The problem is to assign cells to the switches of a PCS network in an efficientmanner. We consider two types of costs. First is the cost of handoffs between cells. Second is the cost of cabling between a cell site and its associated switch. There is constraint on the problem by the call volume handling capacity of switch. This paper describes Firefly Algorithm with Heuristic Method and proposes a possible way it tosolve the problem of assignment of cells of a geographical area to the available number of switches based on the minimization of total cost for the assignment.

  11. Airport Gate Assignment A Hybrid Model and Implementation

    CERN Document Server

    2009-01-01

    With the rapid development of airlines, airports today become much busier and more complicated than previous days. During airlines daily operations, assigning the available gates to the arriving aircrafts based on the fixed schedule is a very important issue, which motivates researchers to study and solve Airport Gate Assignment Problems (AGAP) with all kinds of state-of-the-art combinatorial optimization techniques. In this paper, we study the AGAP and propose a novel hybrid mathematical model based on the method of constraint programming and 0 - 1 mixed-integer programming. With the objective to minimize the number of gate conflicts of any two adjacent aircrafts assigned to the same gate, we build a mathematical model with logical constraints and the binary constraints. For practical considerations, the potential objective of the model is also to minimize the number of gates that airlines must lease or purchase in order to run their business smoothly. We implement the model in the Optimization Programming L...

  12. Hiding Satisfying Assignments: Two are Better than One

    CERN Document Server

    Achlioptas, D; Moore, Cristopher; Achlioptas, Dimitris; Jia, Haixia; Moore, Cristopher

    2005-01-01

    The evaluation of incomplete satisfiability solvers depends critically on the availability of hard satisfiable instances. A plausible source of such instances consists of random k-SAT formulas whose clauses are chosen uniformly from among all clauses satisfying some randomly chosen truth assignment A. Unfortunately, instances generated in this manner tend to be relatively easy and can be solved efficiently by practical heuristics. Roughly speaking, as the formula's density increases, for a number of different algorithms, A acts as a stronger and stronger attractor. Motivated by recent results on the geometry of the space of satisfying truth assignments of random k-SAT and NAE-k-SAT formulas, we introduce a simple twist on this basic model, which appears to dramatically increase its hardness. Namely, in addition to forbidding the clauses violated by the hidden assignment A, we also forbid the clauses violated by its complement, so that both A and complement of A are satisfying. It appears that under this "symm...

    Full Text Available The Faculty of Dental Sciences, University of Peradeniya has been conducting formal introductory courses in ICT for undergraduates at their entry level. Although senior students do not get an opportunity for ICT education they will be required to perform tasks such as assignments, reports, referencing using ICT tools.Dental undergraduate students’ proficiency in ICT was tested on randomly selected groups from three senior batches. Total performance of all students tested showed that the MCQ score (53.4, SD 8.0 has exceeded the pass mark and practical test (44.0, SD 7.2 has recorded well below. Individual tests on the Practical components also showed that students were extremely weak in Excel (8.1, SD 2.2 and well below passmark in Word (16.9, SD 2.9 and Powerpoint (19.0, SD 5.3 tasks.This indicates that considering the basic nature of the questions in this ICT proficiency test, students have displayed a low level of skill in the practical component. However the total aggregate for the overall student performance (48.8, SD 5.4 has recorded just below the pass mark of 50%. These results reiterate the need for development of a formal supplementary training course in ICT for students in senior batches in the Faculty of Dental Sciences.

  15. Job Assignments under Moral Hazard : The Peter Principle Revisited

    DEFF Research Database (Denmark)

    Koch, Alexander; Nafziger, Julia

    2008-01-01

    Inefficient job assignments are usually explained with incomplete information about employees' abilities or contractual imperfections. We show that inefficient assignments arise even without uncertainty about the employee's ability and with complete contracts. Building on this result we provide a new perspective on the Peter Principle, by incorporating the possibility that an employee works harder. Hence, earnings and output may increase with a promotion only because employees work harder, some doing so to compensate for lacking talent. As a result, promotions are desirable for most employees but may make the least able in a hierarchy level less well off.

  20. Automated Negotiation for Resource Assignment in Wireless Surveillance Sensor Networks

    Directory of Open Access Journals (Sweden)

    2015-11-01

    Full Text Available Due to the low cost of CMOS IP-based cameras, wireless surveillance sensor networks have emerged as a new application of sensor networks able to monitor public or private areas or even country borders. Since these networks are bandwidth intensive and the radioelectric spectrum is limited, especially in unlicensed bands, it is mandatory to assign frequency channels in a smart manner. In this work, we propose the application of automated negotiation techniques for frequency assignment. Results show that these techniques are very suitable for the problem, being able to obtain the best solutions among the techniques with which we have compared them.

  1. Evaluation of a Patient Perspective Module in a Required Medication Safety and Quality Course at a College of Pharmacy

    Directory of Open Access Journals (Sweden)

    Jessica N. Battaglia

    2013-01-01

    Full Text Available Objectives: To develop and evaluate the impact of a module discussing the patient’s perspective on medication errors in a required medication safety course at a college of pharmacy. Methods: Students were required to read Josie’s Story, a true story written by a mother after her daughter died from a medical error, and attend an in-class discussion regarding the book. A questionnaire, which employed a pre-post retrospective method and extracted items from the Caring Ability Inventory, was then administered to measure the change in students’ perceptions of patient care. Additional questions gathered students’ perceptions of the assignment, their personal experiences with the topic, and the importance of medication safety. Results: 120 out of 138 students (response rate = 87% completed the questionnaire. 56% of students indicated they would be more likely to speak with a patient directly about a medication error after reading the book, whereas only 3% were less likely, and 42% indicated they were just as likely. Most students (59% reported that they felt more motivated to learn about medication safety after reading Josie’s Story. Implications: This course previously addressed strategies to prevent medication errors. Successfully adding a component that introduces how a medication error impacted a patient and her family may help motivate students to recognize the importance and need for a culture of safety, personalize how medication errors impact patients, and provide a venue for students to gain patient centeredness and caring skills.

  4. Causal effects of single-sex schools on college entrance exams and college attendance: random assignment in Seoul high schools.

    Park, Hyunjoon; Behrman, Jere R; Choi, Jaesung

    2013-04-01

    Despite the voluminous literature on the potentials of single-sex schools, there is no consensus on the effects of single-sex schools because of student selection of school types. We exploit a unique feature of schooling in Seoul-the random assignment of students into single-sex versus coeducational high schools-to assess causal effects of single-sex schools on college entrance exam scores and college attendance. Our validation of the random assignment shows comparable socioeconomic backgrounds and prior academic achievement of students attending single-sex schools and coeducational schools, which increases the credibility of our causal estimates of single-sex school effects. The three-level hierarchical model shows that attending all-boys schools or all-girls schools, rather than coeducational schools, is significantly associated with higher average scores on Korean and English test scores. Applying the school district fixed-effects models, we find that single-sex schools produce a higher percentage of graduates who attended four-year colleges and a lower percentage of graduates who attended two-year junior colleges than do coeducational schools. The positive effects of single-sex schools remain substantial, even after we take into account various school-level variables, such as teacher quality, the student-teacher ratio, the proportion of students receiving lunch support, and whether the schools are public or private.

  16. Assigning Main Orientation to an EOH Descriptor on Multispectral Images.

    Science.gov (United States)

    Li, Yong; Shi, Xiang; Wei, Lijun; Zou, Junwei; Chen, Fang

    2015-01-01

    This paper proposes an approach to compute an EOH (edge-oriented histogram) descriptor with main orientation. EOH has a better matching ability than SIFT (scale-invariant feature transform) on multispectral images, but does not assign a main orientation to keypoints. Alternatively, it tends to assign the same main orientation to every keypoint, e.g., zero degrees. This limits EOH to matching keypoints between images of translation misalignment only. Observing this limitation, we propose assigning to keypoints the main orientation that is computed with PIIFD (partial intensity invariant feature descriptor). In the proposed method, SIFT keypoints are detected from images as the extrema of difference of Gaussians, and every keypoint is assigned to the main orientation computed with PIIFD. Then, EOH is computed for every keypoint with respect to its main orientation. In addition, an implementation variant is proposed for fast computation of the EOH descriptor. Experimental results show that the proposed approach performs more robustly than the original EOH on image pairs that have a rotation misalignment. PMID:26140348

  17. Consistent assignment of the vibrations of monosubstituted benzenes.

    Science.gov (United States)

    Gardner, Adrian M; Wright, Timothy G

    2011-09-21

    We investigate the consistency of the labeling and assignments of the vibrations of the monosubstituted benzenes in the electronic ground state. In doing so, we also identify some inconsistencies in the labeling of the benzene modes. We commence by investigating the behavior of the benzene vibrations as one hydrogen is replaced by an artificial atomic substituent of increasing mass via quantum chemical calculations; the wavenumber variations with mass give insight into the assignments. We also examine how well the monohalobenzene vibrations can be described in terms of the benzene ones: consistent with some recent studies, we conclude that this is futile in a significant number of cases. We then show that "isotopic wavenumbers" obtained by artificially changing the mass of the fluorine atom in fluorobenzene are in very good agreement with the wavenumbers obtained via explicit calculation for the relevant monohalobenzene (chlorobenzene, bromobenzene, and iodobenzene) vibrations. As a consequence, we propose that the vibrations of monofluorobenzene be used as the basis for labelling the vibrational assignments of monosubstituted benzenes. As well as the four monohalobenzenes, we also apply this approach to the vibrations of aniline, toluene, benzonitrile, phenylacetylene, phenylphosphine, and nitrobenzene. This has allowed a much more consistent picture of the vibrational assignments to be obtained across ten monosubstituted benzenes. PMID:21950860

  1. Assigning Main Orientation to an EOH Descriptor on Multispectral Images

    Directory of Open Access Journals (Sweden)

    2015-07-01

    Full Text Available This paper proposes an approach to compute an EOH (edge-oriented histogram descriptor with main orientation. EOH has a better matching ability than SIFT (scale-invariant feature transform on multispectral images, but does not assign a main orientation to keypoints. Alternatively, it tends to assign the same main orientation to every keypoint, e.g., zero degrees. This limits EOH to matching keypoints between images of translation misalignment only. Observing this limitation, we propose assigning to keypoints the main orientation that is computed with PIIFD (partial intensity invariant feature descriptor. In the proposed method, SIFT keypoints are detected from images as the extrema of difference of Gaussians, and every keypoint is assigned to the main orientation computed with PIIFD. Then, EOH is computed for every keypoint with respect to its main orientation. In addition, an implementation variant is proposed for fast computation of the EOH descriptor. Experimental results show that the proposed approach performs more robustly than the original EOH on image pairs that have a rotation misalignment.

    Full Text Available Idea is a thought or collection of thoughts that are important to decision making and problem solving.  The purpose of this research was to analysis the factors contributing to difficulty in generating ideas among technical students.  A total of 375 technical students from four technical universities in Malaysia were randomly selected as samples.  A set of questionnaires was developed and used as research instrument.  The findings indicated that a total of 319 (85.1% technical students faced difficulties in solving individual assignments.  Most of the problem faced by technical students is the difficulty of generating ideas for solving individual assignments.  The most difficult individual assignment is critical review or summary of articles.  Deadlock of ideas is the most important factor in the difficulty to generate ideas among technical students.  A total of 261 students (69.6% also believed that the difficulty of generating ideas is a key factor affecting the achievement of the students’ assignments.  As a result, difficulties in generating ideas lead to students having problems in completing their assignment.  Therefore, students need to learn higher order thinking skills which are essential skills enabling students to generate ideas and consequently complete assignments

  5. Assigning strains to bacterial species via the internet

    2009-01-01

    Full Text Available Abstract Background Methods for assigning strains to bacterial species are cumbersome and no longer fit for purpose. The concatenated sequences of multiple house-keeping genes have been shown to be able to define and circumscribe bacterial species as sequence clusters. The advantage of this approach (multilocus sequence analysis; MLSA is that, for any group of related species, a strain database can be produced and combined with software that allows query strains to be assigned to species via the internet. As an exemplar of this approach, we have studied a group of species, the viridans streptococci, which are very difficult to assign to species using standard taxonomic procedures, and have developed a website that allows species assignment via the internet. Results Seven house-keeping gene sequences were obtained from 420 streptococcal strains to produce a viridans group database. The reference tree produced using the concatenated sequences identified sequence clusters which, by examining the position on the tree of the type strain of each viridans group species, could be equated with species clusters. MLSA also identified clusters that may correspond to new species, and previously described species whose status needs to be re-examined. A generic website and software for electronic taxonomy was developed. This site http://www.eMLSA.net allows the sequences of the seven gene fragments of a query strain to be entered and for the species assignment to be returned, according to its position within an assigned species cluster on the reference tree. Conclusion The MLSA approach resulted in the identification of well-resolved species clusters within this taxonomically challenging group and, using the software we have developed, allows unknown strains to be assigned to viridans species via the internet. Submission of new strains will provide a growing resource for the taxonomy of viridans group streptococci, allowing the recognition of potential new species and taxonomic anomalies. More generally, as the software at the MLSA website is generic, MLSA schemes and strain databases for other groups of related species can be hosted at this website, providing a portal for microbial electronic taxonomy.

    2001-01-01

    Full Text Available This article reports an exploratory study of lecturers' perceptions of out-of-class academic collaboration (OCAC among students at a large Singapore university. Two types of OCAC were investigated: collaboration initiated by students, e.g., groups decide on their own to meet to prepare for exams, and collaboration required by teachers, e.g., teachers assign students to do projects in groups. Data were collected via one-on-one interviews with 18 faculty members from four faculties at the university. Findings suggest that OCAC, especially of a teacher-required kind, is fairly common at the university. Faculty members' views on factors affecting the success of OCAC are discussed for the light they might shed on practices to enhance the effectiveness of OCAC.

  8. Balance Calibration – A Method for Assigning a Direct-Reading Uncertainty to an Electronic Balance.

    Paper Title: Balance Calibration – A method for assigning a direct-reading uncertainty to an electronic balance. Intended Audience: Those who calibrate or use electronic balances. Abstract: As a calibration facility, we provide on-site (at the customer’s location) calibrations of electronic balances for customers within our company. In our experience, most of our customers are not using their balance as a comparator, but simply putting an unknown quantity on the balance and reading the displayed mass value. Manufacturer’s specifications for balances typically include specifications such as readability, repeatability, linearity, and sensitivity temperature drift, but what does this all mean when the balance user simply reads the displayed mass value and accepts the reading as the true value? This paper discusses a method for assigning a direct-reading uncertainty to a balance based upon the observed calibration data and the environment where the balance is being used. The method requires input from the customer regarding the environment where the balance is used and encourages discussion with the customer regarding sources of uncertainty and possible means for improvement; the calibration process becomes an educational opportunity for the balance user as well as calibration personnel. This paper will cover the uncertainty analysis applied to the calibration weights used for the field calibration of balances; the uncertainty is calculated over the range of environmental conditions typically encountered in the field and the resulting range of air density. The temperature stability in the area of the balance is discussed with the customer and the temperature range over which the balance calibration is valid is decided upon; the decision is based upon the uncertainty needs of the customer and the desired rigor in monitoring by the customer. Once the environmental limitations are decided, the calibration is performed and the measurement data is entered into a custom spreadsheet. The spreadsheet uses measurement results, along with the manufacturer’s specifications, to assign a direct-read measurement uncertainty to the balance. The fact that the assigned uncertainty is a best-case uncertainty is discussed with the customer; the assigned uncertainty contains no allowance for contributions associated with the unknown weighing sample, such as density, static charges, magnetism, etc. The attendee will learn uncertainty considerations associated with balance calibrations along with one method for assigning an uncertainty to a balance used for non-comparison measurements.

  10. 4D experiments measured with APSY for automated backbone resonance assignments of large proteins

    International Nuclear Information System (INIS)

    Detailed structural and functional characterization of proteins by solution NMR requires sequence-specific resonance assignment. We present a set of transverse relaxation optimization (TROSY) based four-dimensional automated projection spectroscopy (APSY) experiments which are designed for resonance assignments of proteins with a size up to 40 kDa, namely HNCACO, HNCOCA, HNCACB and HN(CO)CACB. These higher-dimensional experiments include several sensitivity-optimizing features such as multiple quantum parallel evolution in a ‘just-in-time’ manner, aliased off-resonance evolution, evolution-time optimized APSY acquisition, selective water-handling and TROSY. The experiments were acquired within the concept of APSY, but they can also be used within the framework of sparsely sampled experiments. The multidimensional peak lists derived with APSY provided chemical shifts with an approximately 20 times higher precision than conventional methods usually do, and allowed the assignment of 90 % of the backbone resonances of the perdeuterated primase-polymerase ORF904, which contains 331 amino acid residues and has a molecular weight of 38.4 kDa.

  11. A Divide-and-Conquer Scheme for Assigning Roles in Multi-Channel Wireless Mesh Networks

    Darties, Benoit; Duda, Andrzej

    2009-01-01

    A multi-channel MAC seems to be an interesting approach for improving network throughput by multiplexing transmissions over orthogonal channels. In particular, Molecular MAC has recently proposed to modify the standard IEEE 802.11 DCF access method to use dynamic channel switching for efficient packet forwarding over multiple hops. However, this MAC layer requires role and channel assignment to nodes: some of them use a static channel, while others dynamically switch to neighbor channels on-demand. To assign roles and channels, we extend the notion of the Weakly Connected Dominating Set, the structure already used in clustering. More precisely, we adapt the WCDS structure and introduce new constraints to define what we call a reversible WCDS (r-WCDS), which is particularly suitable for wireless mesh networks operating under Molecular MAC. We propose a divide-and-conquer scheme that partitions the network into clusters with one leader per cluster solving a MILP formulation to assign roles in its cluster. By ap...

    Within intellectual disability nursing students are prepared within a biopsychosocialeducational model and curriculum address these challenges. Using a simulated learning environment has great potential for promoting competence and in-depth knowledge of substantive topics relevant to practice. This article presents an assignment designed to more closely resemble real-world activities to allow students develop and exercise skills that translate to practice activities and incorporates a student's reflective comments on the process. The assignment was designed to foster intellectual disability student nurses ability to facilitate family/client education. The aim of the assignment was fulfilled through the students designing a clinical skill teaching session that could be used with families/clients. The sessions were recorded and the student reviewed their recording to reflect on their performance and to self assess. To facilitate student learning the modules academic lecturer also reviewed the recording and both lecturer and student meet to discuss the reflection and self assessment. PMID:23602694

    Md Shamsul Arefin

    2012-12-01

    Full Text Available This work presents a technique for the chirality (n, m assignment of semiconducting single wall carbon nanotubes by solving a set of empirical equations of the tight binding model parameters. The empirical equations of the nearest neighbor hopping parameters, relating the term (2n, m with the first and second optical transition energies of the semiconducting single wall carbon nanotubes, are also proposed. They provide almost the same level of accuracy for lower and higher diameter nanotubes. An algorithm is presented to determine the chiral index (n, m of any unknown semiconducting tube by solving these empirical equations using values of radial breathing mode frequency and the first or second optical transition energy from resonant Raman spectroscopy. In this paper, the chirality of 55 semiconducting nanotubes is assigned using the first and second optical transition energies. Unlike the existing methods of chirality assignment, this technique does not require graphical comparison or pattern recognition between existing experimental and theoretical Kataura plot.

    Full Text Available Wireless Sensor Networks (WSNs have emerged to meet the multimedia requirements in new emerging applications. So it’s important for WSN to have an adaptive and energy-efficient TDMA-CSMA based MAC protocol which significantly reduces energy consumption of the network. Here, this study proposes an Adaptive MAC protocol with effective TDMA time-slot assignment and CSMA contention window adaptation for WSN. This approach mainly consists of two parts which are TDMA time-slot assignment and CSMA contention window adaptation. Through TDMA time-slot assignment it is possible for the receiver nodes to re-organize the timeslots among the sender nodes according to their accessible traffic load. Through CSMA contention window, the network can reduce the latency occurring between the nodes during the transmission.

    Full Text Available Under the auspices of the Centre for Curriculum Decelopment, a three-cycle action research study was carried out in three primary schools in Yogyakarta with the aim of developing a model of teaching English to primary school students. The model consists of five parts: Opening, Content Focus, Language Focus, Communication Focus, and Closing. The model, requiring that learning tasks involve active participation of students, both physically and mentally, supported by the use of media suitable for young learners, was developmentally fully implemented. The results showed that efforts were mostly made to establish teacher-student rapport in the first cycle, in which success in classroom management was gradually reached. This led to the easier second cycle, which was characterized by increasing teacher talk (classroom English, the use of interesting media, and more active students' participation in the tasks involving various games which successfully elicited students' English. All of this was solidified in the third cycle. The conclusion is that with the three aspects being focused successively, teacher-student good rapport being established, various media being used, and competing and cooperative tasks being assigned in balance, joyful and effective learning is likely to occur.

  20. Introductory Videos: An Analysis of Student Use Patterns

    Directory of Open Access Journals (Sweden)

    2009-11-01

    Full Text Available In a distance-learning environment, an introductory video allows students to see and hear their instructor, affording the instructor the ability to efficiently communicate course information to a large number of students. This study considers the use of these introductory videos and made use of the Blackboard course management system (Blackboard, 2008 during two consecutive academic semesters to track and evaluate student usage patterns. Results found students used the video throughout the semester, although an ARIMA (autoregressive integrated moving average analysis found a significant negative trend. An additional exploratory analysis conducted with a linear regression and t-test found that student use of the video during the first half of the spring semester was significantly greater than during the second half of the semester. This finding may suggest that this type of video, a general course introduction, is much more useful to students early in a semester than it is in the latter half of a course. Additionally, this type of video may be viewed in the second half of a course to access more specific content information to assist with assignments but does not require frequent viewing.
