  2. Interactive Assignments for Online Students

    Pam Lowry

    2009-04-01

    Full Text Available Students can experience first hand through interactive assignments what is involved in teaching an online course. Most students develop a whole new appreciation for the student learning process. Faculty are beginning to realize that online instruction is more than a series of readings posted to a course management system. This paper summarizes the faculty member's instructional strategies involved when creating student interaction assignments. The paper also summarizes the assignments, discussion board, and trends in education from the student's perspective. In summary, it concludes with the faculty's overall perspective concerning these assignments and how the assignments could be more effective for the student.

The model exploits withinstudent variation in homework across subjects in a sample of primary school students who have the same teacher in two related subjects; mathematics and science. Unobserved teacher and student characteristics are thus conditioned out of the model and the identification rests on random relative homework assignment across the subj...

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

    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.

  11. Data requirements for reliable chemical shift assignments in deuterated proteins

    The information required for chemical shift assignments in large deuterated proteins was investigated using a Monte Carlo approach (Hitchens et al., 2002). In particular, the consequences of missing amide resonances on the reliability of assignments derived from Cα and CO or from Cα and Cβ chemical shifts was investigated. Missing amide resonances reduce both the number of correct assignments as well as the confidence in these assignments. More significantly, a number of undetectable errors can arise when as few as 9% of the amide resonances are missing from the spectra. However, the use of information from residue specific labeling as well as local and long-range distance constraints improves the reliability and extent of assignment. It is also shown that missing residues have only a minor effect on the assignment of protein-ligand complexes using Cα and CO chemical shifts and Cα inter-residue connectivity, provided that the known chemical shifts of the unliganded protein are utilized in the assignment process

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

    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.

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

    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.

  15. Everyone Likes a Challenge: Getting Students' Attention with Interactive Games and Authentic Assignments

    Theresa McDevitt

    2013-10-01

    Full Text Available Most college students today have little trouble finding information through Google, Facebook, Twitter, and Wikipedia. They find it more challenging when asked to locate, evaluate, and ethically use the highest quality and most appropriate resources, which might require them to look beyond the first few hits in a Google search. Academic librarians are spending more time designing and delivering instruction to help students develop these important information literacy skills. How can librarians design their classes to promote the learning of these higher-order mental processes? How can they capture the attention of their students and engage them in the learning process? Adding games, activities, and authentic or problem based assignments to existing instruction sessions may be the answer. This article will discuss how librarians at Indiana University of Pennsylvania (IUP Libraries have made instruction more engaging and effective by adding action to orientations and authenticity to assignments.

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

    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.

  18. The Impact of Teacher-Student Gender Matches: Random Assignment Evidence from South Korea

    Jaegeum Lim; Jonathan Meer

    2015-01-01

    Gender disparities in academic performance may be driven in part by the interaction of teacher and student gender, but systematic sorting of students into classrooms makes it difficult to identify causal effects. We use the random assignment of students to Korean middle school classrooms and show that the female students perform substantially better on standardized tests when assigned to female teachers; there is little effect on male students.

  3. Embedded Library Guides in Learning Management Systems Help Students Get Started on Research Assignments

    Dominique Daniel

    2016-03-01

    widgets and links, although high use guides tended to have slightly fewer widgets. Of those guides, 55% were assigned at the course level, 30% at the department level and 13% at the college level. Over half the librarians with at least one high use guide conducted a library instruction session in which they used or promoted that guide. For 39% of the courses with high-use guides, the librarian was actively engaged with the faculty and students via the LMS, but others reported no specific involvement in courses. Conclusion – Those students who used library guides reported the guides helped them get started on their research paper or assignment and find research materials, two areas for which previous studies show students have great difficulty. Since the majority of students did not notice the link to the library guide in the LMS, librarians could emphasize it in the news section of the course, which gets much more attention. Within library guides, simpler groupings of links might be easier for students to use, but this conclusion would require further research to confirm. In any case, nearly half of all high use guides were not promoted in any way by librarians, but simply automatically embedded in the LMS, a sign that passive embedding may provide an easy way for the library to reach a large number of students early in their academic career. Since the automatic embedding of guides began, guides have seen a dramatic increase in usage.

  4. Neuronal activity in dorsomedial and dorsolateral striatum under the requirement for temporal credit assignment.

    Her, Eun Sil; Huh, Namjung; Kim, Jieun; Jung, Min Whan

    2016-01-01

    To investigate neural processes underlying temporal credit assignment in the striatum, we recorded neuronal activity in the dorsomedial and dorsolateral striatum (DMS and DLS, respectively) of rats performing a dynamic foraging task in which a choice has to be remembered until its outcome is revealed for correct credit assignment. Choice signals appeared sequentially, initially in the DMS and then in the DLS, and they were combined with action value and reward signals in the DLS when choice outcome was revealed. Unlike in conventional dynamic foraging tasks, neural signals for chosen value were elevated in neither brain structure. These results suggest that dynamics of striatal neural signals related to evaluating choice outcome might differ drastically depending on the requirement for temporal credit assignment. In a behavioral context requiring temporal credit assignment, the DLS, but not the DMS, might be in charge of updating the value of chosen action by integrating choice, action value, and reward signals together.

  8. Peer Assignment Review Process for Collaborative E-learning: Is the Student Learning Process Changing?

    Evelyn Kigozi Kahiigi

    2013-01-01

    Full Text Available In recent years collaborative e-learning has been emphasized as a learning method that has facilitated knowledge construction and supported student learning. However some universities especially in developing country contexts are struggling to attain minimal educational benefits from its adoption and use. This paper investigates the application of a peer assignment review process for collaborative e-learning to third year undergraduate students. The study was aimed at evaluating the effect of the peer assignment review process on the student learning process. Data was collected using a survey questionnaire and analyzed using SPSS Version 16.0. While the student reported positive impact of the peer assignment review process in terms of facilitating students to put more effort and improve their work; quick feedback on their assignments; effective sharing and development of knowledge and information and the need of computer competence to manipulate the peer assignment review system, analysis of the quantitative data indicated that the process had limited effect on the learning process. This is attributed to lack of review skills, absence of lecturer scaffolding, low ICT literacy levels and change management.

  10. Simulated annealing algorithm for solving chambering student-case assignment problem

    Ghazali, Saadiah; Abdul-Rahman, Syariza

    2015-12-01

    The problem related to project assignment problem is one of popular practical problem that appear nowadays. The challenge of solving the problem raise whenever the complexity related to preferences, the existence of real-world constraints and problem size increased. This study focuses on solving a chambering student-case assignment problem by using a simulated annealing algorithm where this problem is classified under project assignment problem. The project assignment problem is considered as hard combinatorial optimization problem and solving it using a metaheuristic approach is an advantage because it could return a good solution in a reasonable time. The problem of assigning chambering students to cases has never been addressed in the literature before. For the proposed problem, it is essential for law graduates to peruse in chambers before they are qualified to become legal counselor. Thus, assigning the chambering students to cases is a critically needed especially when involving many preferences. Hence, this study presents a preliminary study of the proposed project assignment problem. The objective of the study is to minimize the total completion time for all students in solving the given cases. This study employed a minimum cost greedy heuristic in order to construct a feasible initial solution. The search then is preceded with a simulated annealing algorithm for further improvement of solution quality. The analysis of the obtained result has shown that the proposed simulated annealing algorithm has greatly improved the solution constructed by the minimum cost greedy heuristic. Hence, this research has demonstrated the advantages of solving project assignment problem by using metaheuristic techniques.

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

    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

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

    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.

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

    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

  3. Introducing chemical biology applications to introductory organic chemistry students using series of weekly assignments.

    Kanin, Maralee R; Pontrello, Jason K

    2016-03-01

    Calls to bring interdisciplinary content and examples into introductory science courses have increased, yet strategies that involve course restructuring often suffer from the need for a significant faculty commitment to motivate change. Minimizing the need for dramatic course reorganization, the structure, reactivity, and chemical biology applications of classes of biological monomers and polymers have been integrated into introductory organic chemistry courses through three series of semester-long weekly assignments that explored (a) Carbohydrates and Oligosaccharides, (b) Amino Acids, Peptides, and Proteins, and (c) Nucleosides, Nucleotides, and Nucleic Acids. Comparisons of unannounced pre- and post tests revealed improved understanding of a reaction introduced in the assignments, and course examinations evaluated cumulative assignment topics. Course surveys revealed that demonstrating biologically relevant applications consistently throughout the semesters enhanced student interest in the connection between basic organic chemistry content and its application to new and unfamiliar bio-related examples. Covering basic material related to these classes of molecules outside of the classroom opened lecture time to allow the instructor to further build on information developed through the weekly assignments, teaching advanced topics and applications typically not covered in an introductory organic chemistry lecture course. Assignments were implemented as homework, either with or without accompanying discussion, in both laboratory and lecture organic courses within the context of the existing course structures. © 2015 by The International Union of Biochemistry and Molecular Biology, 44:168-178, 2016.

    Lasry, Nathaniel; Charles, Elizabeth; Whittaker, Chris

    2014-06-01

    Technology-rich student-centered classrooms such as SCALE-UP and TEAL are designed to actively engage students. We examine what happens when the design of the classroom (conventional or teacher-centered versus student-centered classroom spaces) is consistent or inconsistent with the teacher's epistemic beliefs about learning and teaching (traditional or teacher-centered versus student-centered pedagogies). We compare two types of pedagogical approaches and two types of classroom settings through a quasiexperimental 2×2 factorial design. We collected data from 214 students registered in eight sections of an introductory calculus-based mechanics course given at a Canadian publicly funded two-year college. All students were given the Force Concept Inventory at the beginning and at the end of the 15-week-long course. We then focused on six teachers assigned to teach in the student-centered classroom spaces. We used qualitative observations and the Approaches to Teaching Inventory (ATI), a self-reported questionnaire, to determine the teachers' epistemic beliefs (teacher-centered or student-centered) and how these beliefs affected their use of the space and their students' conceptual learning. We report four main findings. First, the student-centered classroom spaces are most effective when used with student-centered pedagogies. Second, student-centered classrooms are ineffective when used with teacher-centered pedagogies and may have negative effects for students with low prior knowledge. Third, we find a strong correlation between six instructors' self-reported epistemic beliefs of student centeredness and their classes' average normalized gain (r =0.91; p =0.012). Last, we find that some instructors are more willing to adopt student-centered teaching practices after using student-centered classroom spaces. These data suggest that student-centered classrooms are effective only when instructors' epistemic framework of teaching and learning is consistent with a student

  5. Process Model Improvement for Source Code Plagiarism Detection in Student Programming Assignments

    Dragutin KERMEK

    2016-04-01

    Full Text Available In programming courses there are various ways in which students attempt to cheat. The most commonly used method is copying source code from other students and making minimal changes in it, like renaming variable names. Several tools like Sherlock, JPlag and Moss have been devised to detect source code plagiarism. However, for larger student assignments and projects that involve a lot of source code files these tools are not so effective. Also, issues may occur when source code is given to students in class so they can copy it. In such cases these tools do not provide satisfying results and reports. In this study, we present an improved process model for plagiarism detection when multiple student files exist and allowed source code is present. In the research in this paper we use the Sherlock detection tool, although the presented process model can be combined with any plagiarism detection engine. The proposed model is tested on assignments in three courses in two subsequent academic years.

    The primary goal of this study was to longitudinally evaluate the homework assignment completion patterns of middle school age adolescents with ADHD, their associations with academic performance, and malleable predictors of homework assignment completion. Analyses were conducted on a sample of 104 middle school students comprehensively diagnosed with ADHD and followed for 18 months. Multiple teachers for each student provided information about the percentage of homework assignments turned in at five separate time points and school grades were collected quarterly. Results showed that agreement between teachers with respect to students assignment completion was high, with an intraclass correlation of .879 at baseline. Students with ADHD were turning in an average of 12% fewer assignments each academic quarter in comparison to teacher-reported classroom averages. Regression analyses revealed a robust association between the percentage of assignments turned in at baseline and school grades 18 months later, even after controlling for baseline grades, achievement (reading and math), intelligence, family income, and race. Cross-lag analyses demonstrated that the association between assignment completion and grades was reciprocal, with assignment completion negatively impacting grades and low grades in turn being associated with decreased future homework completion. Parent ratings of homework materials management abilities at baseline significantly predicted the percentage of assignments turned in as reported by teachers 18 months later. These findings demonstrate that homework assignment completion problems are persistent across time and an important intervention target for adolescents with ADHD. PMID:26931065

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

    Marcie Lynne Jacklin

    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.

    2012-12-01

    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.

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

    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.

  5. Why the Rhetoric of CS Programming Assignments Matters

    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.

    2014-12-01

    Encourage students to write a detailed, analytical report correlating classroom discussions to an important historical event or a current event. Motivate students interview an expert from industry on a topic that was discussed in class. Ask the students to submit a report with supporting sketches, drawings, circuit diagrams and graphs. Propose that the students generate a complete a set of reading responses pertaining to an assigned topic. Require each student to bring in one comment or one question about an assigned reading. The assignment should be a recent publication in an appropriate journal. Have the students conduct a web search on an assigned topic. Ask them to generate a set of ideas that can relate to classroom discussions. Provide the students with a study guide. The study guide should provide about 10 or 15 short topics. Quiz the students on one or two of the topics. Encourage the students to design or develop some creative real-world examples based on a chapter discussed or a topic of interest. Require that students originate, develop, support and defend a viewpoint using a specifically assigned material. Make the students practice using or utilizing a set of new technical terms they have encountered in an assigned chapter. Have students develop original examples explaining the different terms. Ask the students to select one important terminology from the previous classroom discussions. Encourage the students to explain why they selected that particular word. Ask them to talk about the importance of the terminology from the point of view of their educational objectives and future career. Angelo, T. A. (1991).

  12. Grading Practices and Considerations of Graduate Students at the Beginning of their Teaching Assignment

    Yerushalmi, Edit; Maries, Alexandru; Henderson, Charles R; Singh, Chandralekha

    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.

    Carabez, Rebecca; Pellegrini, Marion; Mankovitz, Andrea; Eliason, Michele J; Dariotis, Wei Ming

    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.

  6. College students classified with ADHD and the foreign language requirement.

    Sparks, Richard L; Javorsky, James; Philips, Lois

    2004-01-01

    The conventional assumption of most disability service providers is that students classified as having attention-deficit/hyperactivity disorder (ADHD) will experience difficulties in foreign language (FL) courses. However, the evidence in support of this assumption is anecdotal. In this empirical investigation, the demographic profiles, overall academic performance, college entrance scores, and FL classroom performance of 68 college students classified as having ADHD were examined. All students had graduated from the same university over a 5-year period. The findings showed that all 68 students had completed the university's FL requirement by passing FL courses. The students' college entrance scores were similar to the middle 50% of freshmen at this university, and their graduating grade point average was similar to the typical graduating senior at the university. The students had participated in both lower (100) and upper (200, 300, 400) level FL courses and had achieved mostly average and above-average grades (A, B, C) in these courses. One student had majored and eight students had minored in an FL. Two thirds of the students passed all of their FL courses without the use of instructional accommodations. In this study, the classification of ADHD did not appear to interfere with participants' performance in FL courses. The findings suggest that students classified as having ADHD should enroll in and fulfill the FL requirement by passing FL courses. PMID:15493238

    Guillemin, Victor; Sabatini, Silvia; Zara, Catalin

    2013-01-01

    The concept of assignments was introduced in [GGK99] as a method for extracting geometric information about group actions on manifolds from combinatorial data encoded in the infinitesimal orbit-type stratification. In this paper we will answer in the affirmative a question posed in [GGK99] by showing that the equivariant cohomology ring of $M$ is to a large extent determined by this data.

  13. Effects of Numerical Requirement System on Students' Learning Strategies

    Fani Tuti Handayani

    2015-08-01

    Full Text Available Research on the impacts of the ‘requirement system’ on student learning is still rare, however the system is still widely applied by Dental Schools in many countries. The major consequent of this system is the unpreparedness of students’ learning prior to presenting patients with particular complaints. Objective: This study aimed to explore the effect of the ‘requirement system’ on students’ learning strategy in Dental Education University of Jenderal Soedirman. Methods: This was a qualitative-phenomenography study. The collection of data was through observations and interviews. The number of subjects was 13 students of the same batch in a clinical education level. Observations by 2 clinical teachers were done in advance and lasted for six weeks, followed by in-depth interviews. Results: Interviews revealed that application of the ‘requirement system’ had prompted the students to get the patients and to learn or not learn correspondingly to the specified cases. Observations revealed that preparation for learning did not consequently lead to students’ performance in doing clinical work. Conclusion: ‘Requirement system’ driven students’ preparation for learning. However, number of cases did not. Modifying the ‘requirement system’ and improving the quality of clinical supervision are two important things suggested by this study.DOI: 10.14693/jdi.v22i2.260

  17. 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

    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.

  20. Integrated Design of Basic Training, Practicum and End-of-Course Assignment Modules in the Teacher Training Degree: Perception of University Teachers, Students, and School Teachers

    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.

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

    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

  4. A framework for assessing learning assistants' reflective writing assignments

    Cochran, Geraldine L.; Brookes, David T.; Kramer, Laird H.

    2013-01-01

    At Florida International University we have implemented a learning assistant (LA) program based on the Colorado Learning Assistant Model. [1] As a part of this program, students take a course on science and mathematics education theory and practice in which they are required to submit written reflections. Past anecdotal evidence suggests that students in the LAP at Florida International University are using these writing assignments to reflect on their teaching experiences. The purpose of this study was to a) determine if the writing assignments submitted give evidence that our students are engaging in reflection and b) determine if our students are engaging in deep levels of reflection. In this investigation, we relied on a rubric based on Hatton and Smith's (1995) [2] "Criteria for the Recognition of Evidence for Different Types of Reflective Writing." In this paper, we document a) a system for characterizing student reflections and b) how we give them feedback.

    Kotb, Magd A.; Elmahdy, Hesham Nabeh; Khalifa, Nour El Deen Mahmoud; El-Deen, Mohamed Hamed Nasr; Lotfi, Mohamed Amr N.

    2015-01-01

    Abstract 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).

    Full Text Available The objective of this proposal is to implement a school day agenda focused on the learning rhythms of students of elementary and secondary schools using a genetic algorithm. The methodology of this proposal takes into account legal requirements and constraints on the assignment of teachers and classrooms in public educational institutions in Colombia. In addition, this proposal provides a set of constraints focused on cognitive rhythms and subjects are scheduled at the most convenient times according to the area of knowledge. The genetic algorithm evolves through a process of mutation and selection and builds a total solution based on the best solutions for each group. Sixteen groups in a school are tested and the results of class schedule assignments are presented. The quality of the solution obtained through the established approach is validated by comparing the results to the solutions obtained using another algorithm.El objetivo de esta propuesta es implementar un horario escolar que tenga en cuenta los ritmos de aprendizaje en los estudiantes de educación primaria y secundaria, utilizando un algoritmo genético. La metodología considera los requerimientos legales y las restricciones necesarias para la asignación de maestros y aulas en instituciones educativas públicas de Colombia.

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

    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.

  16. Fleet Assignment Using Collective Intelligence

    Antoine, Nicolas E.; Bieniawski, Stefan R.; Kroo, Ilan M.; Wolpert, David H.

    2004-01-01

    Product distribution theory is a new collective intelligence-based framework for analyzing and controlling distributed systems. Its usefulness in distributed stochastic optimization is illustrated here through an airline fleet assignment problem. This problem involves the allocation of aircraft to a set of flights legs in order to meet passenger demand, while satisfying a variety of linear and non-linear constraints. Over the course of the day, the routing of each aircraft is determined in order to minimize the number of required flights for a given fleet. The associated flow continuity and aircraft count constraints have led researchers to focus on obtaining quasi-optimal solutions, especially at larger scales. In this paper, the authors propose the application of this new stochastic optimization algorithm to a non-linear objective cold start fleet assignment problem. Results show that the optimizer can successfully solve such highly-constrained problems (130 variables, 184 constraints).

  17. Dissection and dissection-associated required experiences improve student performance in gross anatomy: Differences among quartiles.

    Pizzimenti, Marc A; Pantazis, Nicholas; Sandra, Alexander; Hoffmann, Darren S; Lenoch, Susan; Ferguson, Kristi J

    2016-05-01

    To promote student learning, educational strategies should provide multiple levels of engagement with the subject matter. This study investigated examination data from five first year medical gross anatomy class cohorts (692 students) to determine if enhanced student performance was correlated with learning through dissection in a course that used a rotating dissection schedule coupled with peer teaching and other associated experiences. When students performed two of five weekly dissections for a given unit, their average scores on both laboratory and written examinations tended to increase as compared to when they had completed only one week of dissection (P Students in the upper quartile (UQS) of the class benefited when they had dissected once (92.8%) or twice (92.4%), and these scores were significantly higher than those attained when learning from peers (90.3%, P Students in the lower quartile (LQS) benefited most from the dissection experiences, where practical examination performance was better (77.8% and 80.5%) than when these students learned material from their peers (73.7%, P < 0.01). Although UQS benefited from dissection, LQS benefited to a greater extent in both the practical and written examinations with dissection. Although limited, these data suggest that dissection, coupled with associated educational activities, is an effective pedagogical strategy for learning. Further investigation is required to evaluate the concomitant benefits of peer teaching that are associated with the dissection experience.

  19. Number of repetitions required to retain single-digit multiplication math facts for elementary students.

    Burns, Matthew K; Ysseldyke, Jim; Nelson, Peter M; Kanive, Rebecca

    2015-09-01

    Computational fluency is an important aspect of math proficiency. Despite widely held beliefs about the differential difficulty of single-digit multiplication math facts, little empirical work has examined this issue. The current study analyzed the number of repetitions needed to master multiplication math facts. Data from 15,402 3rd, 4th, and 5th graders were analyzed using a national database. Results suggested that (a) students with lower math skills required significantly (p skilled students; (b) across all students, single-digit multiplication facts with 4s, 5s, 6s, and 7s required significantly (p < .001) more repetition than did 2s and 3s; and (c) the number of practice sessions needed to attain mastery significantly (p < .001) decreased with increase in grade level. Implications for instructional planning and implementation are discussed. PMID:25420042

  2. Active learning in pre-class assignments: Exploring the use of interactive simulations to enhance reading assignments

    Stang, Jared B; Perez, Sarah; Ives, Joss; Roll, Ido

    2016-01-01

    Pre-class reading assignments help prepare students for active classes by providing a first exposure to the terms and concepts to be used during class. We investigate if the use of inquiry-oriented PhET-based activities in conjunction with pre-class reading assignments can improve both the preparation of students for in-class learning and student attitudes towards and engagement with pre-class assignments. Over three course modules covering different topics, students were assigned randomly to complete either a textbook-only pre-class assignment or both a textbook pre-class assignment and a PhET-based activity. The assignments helped prepare students for class, as measured by performance on the pre-class quiz relative to a beginning-of-semester pre-test, but no evidence for increased learning due the PhET activity was observed. Students rated the assignments which included PhET as more enjoyable and, for the topic latest in the semester, reported engaging more with the assignments when PhET was included.

  3. The practical training of students - x-ray technicians and requirements to mentors in clinical bases

    Full text: Introduction: Training of X-ray technicians in Bulgaria takes place in the Medical Colleges to Medical Universities. It's purpose is providing professional training of students in the area of diagnostic imaging, nuclear medicine and radiotherapy. Practical training is based on the scientific and theoretical knowledge and skills and is organized in pedagogic environment, adequate to regularities for a gradual formation of practical skills and habits. The practical training and pre-graduation internship are performed in 1895 from total of 3810 hours, which represents about fifty percent of all training of X-ray technicians. Students are in groups of 2-4 students. Practical training is organized, accomplished and monitored by the teacher training practice with the help of a mentor in the clinical base. Purpose: To present the tasks of practical training of students - X-ray technicians and the requirements for the personal characteristics and activity of mentors. Materials and methods: Documentary method has been used. Literature and normative documents related to the practical training of students in 'X-ray technician' of Medical Colleges have been studied. The job descriptions of senior clinical X-ray technicians have been examined carefully. Results: By analyzing literature sources, we have structured the tasks of practical training and pre-graduation internship of students - X-ray technicians, also we have described the requirements for personal qualities of mentors and systematize the activities they perform.

  11. Linking neuroscientific research on decision making to the educational context of novice students assigned to a multiple-choice scientific task involving common misconceptions about electrical circuits

    Patrice ePotvin

    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.

  12. Students' Awareness and Requirements of Mobile Learning Services in the Higher Education Environment

    Naji S. Alzaza

    2011-01-01

    Full Text Available Problem statement: M-learning is considered as the next generation of e-learning using mobile technologies. Students’ awareness of such technology is one of the most focuses for success adoption. This study aims to investigate students’ awareness and requirements of mobile learning services among Malaysian students in the higher education environment. Approach: The study found that the higher education environment now has the necessary mobile technology infrastructure to utilize m-learning. Results: Moreover, the results show that students have adequate knowledge and good awareness to use such technology in their education environment. Regarding the university mobile applications that students would like to use individually through mobile technologies, the exam result and course registration were the highest in rank, followed by calendar and schedule services. The highest limitations were the cost of transaction and slow data exchange with networks, followed by concerns over confidentiality of personal information. Conclusion: Future research should be conducted with a big number of respondents to ensure the representative and conclusive finding.

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

    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.

  16. Quantum probability assignment limited by relativistic causality.

    Han, Yeong Deok; Choi, Taeseung

    2016-01-01

    Quantum theory has nonlocal correlations, which bothered Einstein, but found to satisfy relativistic causality. Correlation for a shared quantum state manifests itself, in the standard quantum framework, by joint probability distributions that can be obtained by applying state reduction and probability assignment that is called Born rule. Quantum correlations, which show nonlocality when the shared state has an entanglement, can be changed if we apply different probability assignment rule. As a result, the amount of nonlocality in quantum correlation will be changed. The issue is whether the change of the rule of quantum probability assignment breaks relativistic causality. We have shown that Born rule on quantum measurement is derived by requiring relativistic causality condition. This shows how the relativistic causality limits the upper bound of quantum nonlocality through quantum probability assignment. PMID:26971717

  17. Time Students Spend Reading Threaded Discussions in Online Graduate Courses Requiring Asynchronous Participation

    Abbie H. Brown

    2009-12-01

    Full Text Available The authors report the results of a study that provides bases for comparison between the time necessary to participate in courses delivered asynchronously online and courses delivered in a traditional classroom setting. Weekly discussion threads from 21 sections of six courses offered as part of online, degree-granting, accredited, graduate programs were examined. The purpose of this research is to determine whether students are spending more or less time participating in an online course than in a traditional classroom.The discussion size (i.e., the number of words per discussion was determined using the automatic word count function in MS Word. Once the word counts for each course section were determined, the average words per discussion were calculated. The authors used 180 words per minute to calculate the average reading time, based on the work of Ziefle (1998 and Carver (1985, 1990, in order to determine the average minutes per week a student spent reading the discussions.The study indicates that a typical, graduate-level, online, asynchronous discussion requires about one hour a week of reading time, and the time commitment for participatory activity is similar to that of traditional, face-to-face courses, given that it takes under two hours to compose initial messages and responses to the discussion prompt.Although these findings are informative, further research is recommended in the area of time spent on online course activities in terms of student hours earned to enable a direct focus on various student characteristics, such as English language competency and student level.

  1. Calibrated peer review assignments for the earth sciences

    Rudd, J.A., II; Wang, V.Z.; Cervato, C.; Ridky, R.W.

    2009-01-01

    Calibrated Peer Review ??? (CPR), a web-based instructional tool developed as part of the National Science Foundation reform initiatives in undergraduate science education, allows instructors to incorporate multiple writing assignments in large courses without overwhelming the instructor. This study reports successful implementation of CPR in a large, introductory geology course and student learning of geoscience content. For each CPR assignment in this study, students studied web-based and paper resources, wrote an essay, and reviewed seven essays (three from the instructor, three from peers, and their own) on the topic. Although many students expressed negative attitudes and concerns, particularly about the peer review process of this innovative instructional approach, they also recognized the learning potential of completing CPR assignments. Comparing instruction on earthquakes and plate boundaries using a CPR assignment vs. an instructional video lecture and homework essay with extensive instructor feedback, students mastered more content via CPR instruction.

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

    Zeng Jianyang [Duke University, Department of Computer Science (United States); Zhou Pei [Duke University Medical Center, Department of Biochemistry (United States); Donald, Bruce Randall [Duke University, Department of Computer Science (United States)

    2011-08-15

    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

    Actuator/sensor locations and balanced representations of linear systems are considered for a given set of controllability and observability grammians. The case of equally controlled and observed states is given special attention. The assignability of grammians is examined, and the conditions for their existence are presented, along with several algorithms for their determination. Although an arbitrary positive semidefinite matrix is not always assignable, the identity grammian is shown to be always assignable. The results are extended to the case of flexible structures.

  1. Using Open Data as a Material for Introductory Programming Assignments

    Coughlan, Tim

    2015-01-01

    This case study explores why and how open data can be used as a material with which to produce engaging challenges for students as they are introduced to programming. Through describing the process of producing the assignments, and learner responses to them, we suggest that open data is a powerful material for designing learning activities because of its qualities of ease of access and authenticity. We conclude by outlining steps to take in devising and implementing open data-based assignments.

  16. The Use of Mock NSF-type Grant Proposals and Blind Peer Review as the Capstone Assignment in Upper-Level Neurobiology and Cell Biology Courses.

    Itagaki, Haruhiko

    2013-01-01

    Although the use of grant proposals and blind peer review are standard in the natural sciences, their use as a pedagogical tool is rarely mentioned in the literature. As a consequence of dissatisfaction with term papers and literature reviews as the capstone writing experience in 300-level undergraduate biology courses, I have been experimenting with mock NSF-type grant proposals followed by blind peer review as the major assignment in my junior/senior-level classes. The improvement in educational outcomes and competencies due to this assignment appears to be substantial and worth the additional effort on both the students' and instructor's parts. Here, I outline the mechanics of this assignment and its advantages and disadvantages as well as the type of curriculum that is required to support this type of capstone assignment. PMID:24319395

  17. MONTE: An automated Monte Carlo based approach to nuclear magnetic resonance assignment of proteins

    Hitchens, T. Kevin; Lukin, Jonathan A.; Zhan Yiping; McCallum, Scott A.; Rule, Gordon S. [Carnegie Mellon University, Department of Biological Sciences (United States)], E-mail: rule@andrew.cmu.edu

    2003-01-15

    A general-purpose Monte Carlo assignment program has been developed to aid in the assignment of NMR resonances from proteins. By virtue of its flexible data requirements the program is capable of obtaining assignments of both heavily deuterated and fully protonated proteins. A wide variety of source data, such as inter-residue scalar connectivity, inter-residue dipolar (NOE) connectivity, and residue specific information, can be utilized in the assignment process. The program can also use known assignments from one form of a protein to facilitate the assignment of another form of the protein. This attribute is useful for assigning protein-ligand complexes when the assignments of the unliganded protein are known. The program can be also be used as an interactive research tool to assist in the choice of additional experimental data to facilitate completion of assignments. The assignment of a deuterated 45 kDa homodimeric Glutathione-S-transferase illustrates the principal features of the program.

  18. Evaluation of a UMLS Auditing Process of Semantic Type Assignments

    Gu, Huanying; Hripcsak, George; Chen, Yan; Morrey, C. Paul; Elhanan, Gai; Cimino, James J.; Geller, James; Perl, Yehoshua

    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

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

    Wipawee Tharmmaphornphilas

    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.

    Relevance-based explanation is a scheme in which partial assignments to Bayesian belief network variables are explanations (abductive conclusions). We allow variables to remain unassigned in explanations as long as they are irrelevant to the explanation, where irrelevance is defined in terms of statistical independence. When multiple-valued variables exist in the system, especially when subsets of values correspond to natural types of events, the over specification problem, alleviated by inde...

  5. 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

  9. Mapping Learning Outcomes and Assignment Tasks for SPIDER Activities

    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.

  20. Online Prelectures: An Alternative to Textbook Reading Assignments

    Sadaghiani, Homeyra R.

    2012-05-01

    To engage students in a more meaningful discussion of course material and prompt their higher thinking skills, most instructors expect students to read the course textbook for initial exposure to the course content before class. However, as many instructors are aware, most students do not read their textbook throughout the quarter.1,2 At California State Polytechnic University, Pomona (Cal Poly Pomona) we have adopted web-based multimedia learning modules (MLMs) as prelecture assignments to help students to prepare for the class activities. The MLMs place lecture contents into the hands and control of the learners; similar to "flipped"3 or "inverted"4 classroom approaches, this method allows students to receive key course content outside of class and apply and analyze the content actively during class. In addition to initial exposure to basic principle, the MLMs provide additional worked examples that cannot be thoroughly covered in class.

    Full Text Available The paper presents two examples of classroom practices when practical research tasks in primary and secondary school are assigned as homework. The task for primary school students was aimed at developing divergent thinking, which is evidenced and illustrated by some examples of students’ solutions. The task for secondary school students illustrates how these students are able to apply their classroom knowledge of acids, bases and indicators on the substances they can find in everyday life. The students performed the following activities: problem analysis, action planning, and equipment selection/assembling, performing the experiment, measuring (mass, volume, data recording, and drawing conclusions. The results of both tasks served as a basis for introducing new contents in the classroom and stimulated active participation of a larger number of students.Keywords:

  2. Learning Skinner's Verbal Operants: Comparing an Online Stimulus Equivalence Procedure to an Assigned Reading.

    O'Neill, John; Rehfeldt, Ruth Anne; Ninness, Chris; Muñoz, Bridget E; Mellor, James

    2015-10-01

    The purpose of the present study was to compare the effects of an online stimulus equivalence procedure to that of an assigned reading when learning Skinner's taxonomy of verbal behavior. Twenty-six graduate students participated via an online learning management system. One group was exposed to an online stimulus equivalence procedure (equivalence group) that was designed to teach relations among the names, antecedents, consequences, and examples of each elementary verbal operant. A comparison group (reading group) read a chapter from a popular textbook. Tests for the emergence of selection-based and topography-based intraverbal responses were then conducted, as were tests for generalization and maintenance. Overall, results suggest that the online equivalence procedure was not significantly more effective in promoting topography-based responses than the assigned reading. However, performance on selection-based tests was enhanced by the online equivalence procedure as was performance on topography-based tests when participants were required to provide operant names in response to consequences or examples. On average, the equivalence group performed at a level that was 10 percentage points (i.e., a full letter grade) above that of the reading group. The viability of the equivalence-based procedure is discussed in relation to the assigned reading. PMID:27606215

  11. Predicting Assignment Submissions in a Multiclass Classification Problem

    Bogdan Drăgulescu

    2015-08-01

    Full Text Available Predicting student failure is an important task that can empower educators to counteract the factors that affect student performance. In this paper, a part of the bigger problem of predicting student failure is addressed: predicting the students that do not complete their assignment tasks. For solving this problem, real data collected by our university’s educational platform was used. Because the problem consisted of predicting one of three possible classes (multi-class classification, the appropriate algorithms and methods were selected. Several experiments were carried out to find the best approach for this prediction problem and the used data set. An approach of time segmentation is proposed in order to facilitate the prediction from early on. Methods that address the problems of high dimensionality and imbalanced data were also evaluated. The outcome of each approach is shown and compared in order to select the best performing classification algorithm for the problem at hand.

  16. Solving multiconstraint assignment problems using learning automata.

    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

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

    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

  18. A Free-Form Power Experiment to Enhance Student Creativity

    Fons, John T.

    2008-01-01

    Laboratory sessions offer students an opportunity to develop creative problem-solving skills and to better understand the nature of the scientific process through hands-on learning. Unfortunately, traditional procedures are often written in such detail, they require students to do little more than follow step-by-step directions. Under those circumstances, students do not have the opportunity for creative and critical thinking and often lose appreciation for the laboratory setting. To encourage student creativity in the lab, I assign a free-form exercise that requires students to measure their power output when performing an activity of their choosing. Students develop their own experimental procedure and analysis restricted only by equipment availability and safety. The short handout I provide for my students contains no formal procedure or guidelines; it simply lists the requirements for their reports.

    2016-07-01

    The web service DNATCO (dnatco.org) classifies local conformations of DNA molecules beyond their traditional sorting to A, B and Z DNA forms. DNATCO provides an interface to robust algorithms assigning conformation classes called NTC: to dinucleotides extracted from DNA-containing structures uploaded in PDB format version 3.1 or above. The assigned dinucleotide NTC: classes are further grouped into DNA structural alphabet NTA: , to the best of our knowledge the first DNA structural alphabet. The results are presented at two levels: in the form of user friendly visualization and analysis of the assignment, and in the form of a downloadable, more detailed table for further analysis offline. The website is free and open to all users and there is no login requirement. PMID:27150812

  11. Airport Gate Assignment: New Model and Implementation

    Li, Chendong

    2008-01-01

    Airport gate assignment is of great importance in airport operations. In this paper, we study the Airport Gate Assignment Problem (AGAP), propose a new model and implement the model with Optimization Programming language (OPL). With the objective to minimize the number of conflicts of any two adjacent aircrafts assigned to the same gate, we build a mathematical model with logical constraints and the binary constraints, which can provide an efficient evaluation criterion for the Airlines to estimate the current gate assignment. To illustrate the feasibility of the model we construct experiments with the data obtained from Continental Airlines, Houston Gorge Bush Intercontinental Airport IAH, which indicate that our model is both energetic and effective. Moreover, we interpret experimental results, which further demonstrate that our proposed model can provide a powerful tool for airline companies to estimate the efficiency of their current work of gate assignment.

  12. Efficient Credit Assignment through Evaluation Function Decomposition

    Agogino, Adrian; Turner, Kagan; Mikkulainen, Risto

    2005-01-01

    Evolutionary methods are powerful tools in discovering solutions for difficult continuous tasks. When such a solution is encoded over multiple genes, a genetic algorithm faces the difficult credit assignment problem of evaluating how a single gene in a chromosome contributes to the full solution. Typically a single evaluation function is used for the entire chromosome, implicitly giving each gene in the chromosome the same evaluation. This method is inefficient because a gene will get credit for the contribution of all the other genes as well. Accurately measuring the fitness of individual genes in such a large search space requires many trials. This paper instead proposes turning this single complex search problem into a multi-agent search problem, where each agent has the simpler task of discovering a suitable gene. Gene-specific evaluation functions can then be created that have better theoretical properties than a single evaluation function over all genes. This method is tested in the difficult double-pole balancing problem, showing that agents using gene-specific evaluation functions can create a successful control policy in 20 percent fewer trials than the best existing genetic algorithms. The method is extended to more distributed problems, achieving 95 percent performance gains over tradition methods in the multi-rover domain.

  20. Motivating Students to Do Homework

    Kontur, Frederick J.; Terry, Nathan B.

    2014-05-01

    How do you motivate students to do their homework? Some instructors make students' homework scores a significant percentage of the final course grade. In that case, how much course credit is required? Some instructors do not grade homework at all, instead relying on students' intrinsic motivation to learn the course material. Will this actually work? Some instructors might motivate students by having quiz and/or exam problems closely match the assigned homework problems. In this article, we report on the effectiveness of grade incentives, homework-based quiz problems, and intrinsic motivation for 16 semesters of introductory mechanics and introductory electricity and magnetism (E&M) courses at the United States Air Force Academy (USAFA) between fall 2008 and spring 2012.

  6. Competitive Traffic Assignment in Road Networks

    Krylatov Alexander Y.

    2016-09-01

    Full Text Available Recently in-vehicle route guidance and information systems are rapidly developing. Such systems are expected to reduce congestion in an urban traffic area. This social benefit is believed to be reached by imposing the route choices on the network users that lead to the system optimum traffic assignment. However, guidance service could be offered by different competitive business companies. Then route choices of different mutually independent groups of users may reject traffic assignment from the system optimum state. In this paper, a game theoretic approach is shown to be very efficient to formalize competitive traffic assignment problem with various groups of users in the form of non-cooperative network game with the Nash equilibrium search. The relationships between the Wardrop’s system optimum associated with the traffic assignment problem and the Nash equilibrium associated with the competitive traffic assignment problem are investigated. Moreover, some related aspects of the Nash equilibrium and the Wardrop’s user equilibrium assignments are also discussed.

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

    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

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

    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.

    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.

    2012-01-01

    With the increased use of large-scale real-time embedded sensor networks, new control mechanisms are needed to avoid congestion and meet required Quality of Service (QoS) levels. In this paper, we propose a Markov Decision Problem (MDP) to prescribe an optimal query assignment strategy that achieves a trade-off between two QoS requirements: query response time and data validity. Query response time is the time that queries spend in the sensor network until they are solved. Data validity (fres...

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

    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.

  17. Unifying Temporal and Structural Credit Assignment Problems

    Agogino, Adrian K.; Tumer, Kagan

    2004-01-01

    Single-agent reinforcement learners in time-extended domains and multi-agent systems share a common dilemma known as the credit assignment problem. Multi-agent systems have the structural credit assignment problem of determining the contributions of a particular agent to a common task. Instead, time-extended single-agent systems have the temporal credit assignment problem of determining the contribution of a particular action to the quality of the full sequence of actions. Traditionally these two problems are considered different and are handled in separate ways. In this article we show how these two forms of the credit assignment problem are equivalent. In this unified frame-work, a single-agent Markov decision process can be broken down into a single-time-step multi-agent process. Furthermore we show that Monte-Carlo estimation or Q-learning (depending on whether the values of resulting actions in the episode are known at the time of learning) are equivalent to different agent utility functions in a multi-agent system. This equivalence shows how an often neglected issue in multi-agent systems is equivalent to a well-known deficiency in multi-time-step learning and lays the basis for solving time-extended multi-agent problems, where both credit assignment problems are present.

  19. Computational Assignment of Chemical Shifts for Protein Residues

    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 ...

  20. Pole assignment for stochastic systems with unknown coefficients

    陈翰馥[1; 曹希仁[2

    2000-01-01

    This paper solves the exact pole assignment problem for the single-input stochastic systems with unknown coefficients under the controllability assumption which is necessary and sufficient for the arbitrary pole assignment for systems with known coefficients. The system noise is required to be mutually independent with zero mean and bounded second moment. Two approaches to solving the problem are proposed: One is the iterative learning approach which can be applied when the state at a fixed time can be repeatedly observed with different feedback gains; the other is the adaptive control approach which works when the trajectories satisfy a nondegeneracy condition. Both methods are essentially based on stochastic approximation, and the feedback gains are recursively given without invoking the certainty-equivalency-principle.

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

    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. A Useful Metaheuristic for Dynamic Channel Assignment in Mobile Cellular Systems

    Deepak Kumar Singh

    2012-09-01

    Full Text Available The prime objective of a Channel Assignment Problem (CAP is to assign appropriate number of required channels to each cell in a way to achieve both efficient frequency spectrum utilization and minimization of interference effects (by satisfying a number of channel reuse constraints. Dynamic Channel Assignment (DCA assigns the channels to the cells dynamically according to traffic demand, and hence, can provide higher capacity (or lower call blocking probability, fidelity and quality of service than the fixed assignment schemes. Channel assignment algorithms are formulated as combinatorial optimization problems and are NP-hard. Devising a DCA, that is practical, efficient, and which can generate high quality assignments, is challenging. Though Metaheuristic Search techniques like Evolutionary Algorithms, Differential Evolution, Particle Swarm Optimization prove effective in the solution of Fixed Channel Assignment (FCA problems but they still require high computational time and therefore may be inefficient for DCA. A number of approaches have been proposed for the solution of DCA problem but the high complexity of these proposed approaches makes them unsuitable/less efficient for practical use. Therefore, this paper presents an effective and efficient Hybrid Discrete Binary Differential Evolution Algorithm (HDB-DE for the solution of DCA Problem

  6. Evolving Networks with Nonlinear Assignment of Weight

    TANG Chao; TANG Yi

    2006-01-01

    We propose a weighted evolving network model in which the underlying topological structure is still driven by the degree according to the preferential attachment rule while the weight assigned to the newly established edges is dependent on the degree in a nonlinear form. By varying the parameter α that controls the function determining the assignment of weight, a wide variety of power-law behaviours of the total weight distributions as well as the diversity of the weight distributions of edges are displayed. Variation of correlation and heterogeneity in the network is illustrated as well.

  8. Helping Students Elicit and Analyze Service-oriented Requirement Using SPOM(Subject-Predicate-Object Method)%应用SPOM方法辅助获取与分析面向服务需求

    万海; 李文军

    2007-01-01

    In order to design and provide good services, it is necessary for students to describe and understand the customer requirements for services rapidly, to design and plan the services and their behavior, and to schedule service processes effectively. This paper proposes a new service-oriented requirement elicitation and analysis method based on answer set semantic, sketches requirement Meta-model and correlative proofs and algorithms, which can help students represent requirement more declarative and precise. Based on the Meta-model, Subject-Predicate-Object requirement method and specification is presented, by which students can constitute a smooth, small-step, incremental and iterative development process cut in by forms. By applying this method to teach and help students develop service-oriented application, it is clear that it can help students eliminate the miscommunication between developers and users, assure the correctness of the artifacts and make the users active in development cycle.

  18. Towards an intelligent system for the automatic assignment of domains in globular proteins.

    Sternberg, M J; Hegyi, H; Islam, S A; Luo, J; Russell, R B

    1995-01-01

    The automatic identification of protein domains from coordinates is the first step in the classification of protein folds and hence is required for databases to guide structure prediction. Most algorithms encode a single concept based and sometimes do not yield assignments that are consistent with the generally accepted perception. Our development of an automatic approach to identify reliably domains from protein coordinates is described. The algorithm is benchmarked against a manual identification of the domains in 284 representative protein chains. The first step is the domain assignment by distance (DAD) algorithm that considers the density of inter-residue contacts represented in a contact matrix. The algorithm yields 85% agreement with the manual assignment. The paper then considers how the reliability of these assignments could be evaluated. Finally the use of structural comparisons using the STAMP algorithm to validate domain assignment is reported on a test case. PMID:7584461

  20. How to encourage university students to solve physics problems requiring mathematical skills: the 'adventurous problem solving' approach

    DeMul, Frits F. M.; Batlle, Cristina Martin i.; DeBruijn, Imme; Rinzema, Kees

    2004-01-01

    Teaching physics to first-year university students (in the USA: junior/senior level) is often hampered by their lack of skills in the underlying mathematics, and that in turn may block their understanding of the physics and their ability to solve problems. Examples are vector algebra, differential expressions and multi-dimensional integrations, and the Gauss and Ampère laws learnt in electromagnetism courses. To enhance those skills in a quick and efficient way we have developed 'Integrating Mathematics in University Physics', in which students are provided with a selection of problems (exercises) that explicitly deal with the relation between physics and mathematics. The project is based on computer-assisted instruction (CAI), and available via the Internet (http://tnweb.tn.utwente.nl/onderwijs/; or http://www.utwente.nl/; search or click to: CONECT). Normally, in CAI a predefined student-guiding sequence for problem solving is used (systematic problem solving). For self-learning this approach was found to be far too rigid. Therefore, we developed the 'adventurous problem solving' (APS) method. In this new approach, the student has to find the solution by developing his own problem-solving strategy in an interactive way. The assessment of mathematical answers to physical questions is performed using a background link with an algebraic symbolic language interpreter. This manuscript concentrates on the subject of APS.

  3. Molecular test to assign individuals within the Cacopsylla pruni complex.

    Jean Peccoud

    Full Text Available Crop protection requires the accurate identification of disease vectors, a task that can be made difficult when these vectors encompass cryptic species. Here we developed a rapid molecular diagnostic test to identify individuals of Cacopsyllapruni (Scopoli, 1763 (Hemiptera: Psyllidae, the main vector of the European stone fruit yellows phytoplasma. This psyllid encompasses two highly divergent genetic groups that are morphologically similar and that are characterized by genotyping several microsatellite markers, a costly and time-consuming protocol. With the aim of developing species-specific PCR primers, we sequenced the Internal Transcribed Spacer 2 (ITS2 on a collection of C. pruni samples from France and other European countries. ITS2 sequences showed that the two genetic groups represent two highly divergent clades. This enabled us to develop specific primers for the assignment of individuals to either genetic group in a single PCR, based on ITS2 amplicon size. All previously assigned individuals yielded bands of expected sizes, and the PCR proved efficient on a larger sample of 799 individuals. Because none appeared heterozygous at the ITS2 locus (i.e., none produced two bands, we inferred that the genetic groups of C. pruni, whose distribution is partly sympatric, constitute biological species that have not exchanged genes for an extended period of time. Other psyllid species (Cacopsylla, Psylla, Triozidae and Aphalaridae failed to yield any amplicon. These primers are therefore unlikely to produce false positives and allow rapid assignment of C. pruni individuals to either cryptic species.

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

    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.

    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.

    ZHU Xing-hui; ZHU Jin-fu; GONG Zai-wu

    2007-01-01

    A 0-1 integer programming model for weekly fleet assignment was put forward based on linear network and weekly flight scheduling in China. In this model, the objective function is to maximize the total profit of fleet assignment, subject to the constraints of coverage, aircraft flow balance, fleet size, aircraft availability, aircraft usage, flight restriction, aircraft seat capacity,and stopover. Then the branch-and-bound algorithm based on special ordered set was applied to solve the model. At last, a realworld case study on an airline with 5 fleets, 48 aircrafts and 1 786 flight legs indicated that the profit increase was $1591276 one week and the running time was no more than 4 min, which shows that the model and algorithm are fairly good for domestic airline.

    2016-06-01

    Total synthesis of four callyspongiolide stereoisomers led to unambiguous assignment of relative and absolute stereochemistry of the natural product. Key features of the convergent, fully stereocontrolled route include the use of Krische allylation, Kiyooka Aldol reaction, Kociénski-Julia olefination, Still-Gennari olefination, Yamaguchi macrocyclization, and Sonogashira coupling reaction. Biological evaluation of the synthesized compounds against an array of cancer cells revealed that the stereochemistry of the macrolactone core played an important role. PMID:27227371

    Dvořák, Wolfgang; Henzinger, Monika

    2016-01-01

    Ad exchanges are becoming an increasingly popular way to sell advertisement slots on the internet. An ad exchange is basically a spot market for ad impressions. A publisher who has already signed contracts reserving advertisement impressions on his pages can choose between assigning a new ad impression for a new page view to a contracted advertiser or to sell it at an ad exchange. This leads to an online revenue maximization problem for the publisher. Given a new impression to sell decide whe...

    Kelly, F.; Key, P.; Walton, N.

    2014-01-01

    We consider a large-scale Ad-auction where adverts are assigned over a potentially infinite number of searches. We capture the intrinsic asymmetries in information between advertisers, the advert platform and the space of searches: advertisers know and can optimize the average performance of their advertisement campaign; the platform knows and can optimize on each search instance; and, neither party knows the distribution of the infinite number of searches that can occur. We look at maximizin...

  8. File Assignment Policy in Network Storage System

    Cao Qiang; Xie Chang-sheng

    2003-01-01

    Network storage increase capacity and scalability of storage system, data availability and enables the sharing of data among clients. When the developing network technology reduce performance gap between disk and network, however, mismatched policies and access pattern can significantly reduce network storage performance. So the strategy of data placement in system is an important factor that impacts the performance of overall system. In this paper, the two algorithms of file assignment are presented. One is Greed partition that aims at the load balance across all NADs (Network Attached Disk). The other is Sort partition that tries to minimize variance of service time in each NAD. Moreover, we also compare the performance of our two algorithms in practical environment. Our experimental results show that when the size distribution (load characters) of all assigning files is closer and larger, Sort partition provides consistently better response times than Greedy algorithm. However, when the range of all assigning files is wider, there are more small files and access rate is higher, the Greedy algorithm has superior performance in compared with the Sort partition in off-line.

  9. The double-assignment method for the exponential chaotic tabu search in quadratic assignment problems

    Shibata, Kazuaki; Horio, Yoshihiko; Aihara, Kazuyuki

    The quadratic assignment problem (QAP) is one of the NP-hard combinatorial optimization problems. An exponential chaotic tabu search using a 2-opt algorithm driven by chaotic neuro-dynamics has been proposed as one heuristic method for solving QAPs. In this paper we first propose a new local search, the double-assignment method, suitable for the exponential chaotic tabu search, which adopts features of the Lin-Kernighan algorithm. We then introduce chaotic neuro-dynamics into the double-assignment method to propose a novel exponential chaotic tabu search. We further improve the proposed exponential chaotic tabu search with the double-assignment method by enhancing the effect of chaotic neuro-dynamics.

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

    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

    Correct phosphorylation site assignment is a critical aspect of phosphoproteomic analysis. Large-scale phosphopeptide data sets that are generated through liquid chromatography-coupled tandem mass spectrometry (LC-MS/MS) analysis often contain hundreds or thousands of phosphorylation sites that require validation. To this end, we have created PhosphoScore, an open-source assignment program that is compatible with phosphopeptide data from multiple MS levels (MSn). The algorithm takes into acco...

    Adibah Shuib; Wan Nor Ashikin Wan Ahmad Fatthi

    2012-01-01

    Cross docking is a relatively new technique in supply chain operations. It offers limited storage time to maximize the efficiency of goods transshipment. Efficient operation of a cross docking system requires an appropriate coordination of inbound and outbound flows, accurate planning and dynamic scheduling.  The planning strategies at cross docking terminals, which are receiving growing attention today, are the truck-to-door assignment and destination to door assignment problems.

  17. Instructional Insights: Audio Feedback as Means of Engaging the Occupational Therapy Student.

    Nielsen, Sarah K

    2016-01-01

    Constructivist learning approaches require faculty to engage students in the reflective learning process, yet students can begin to view this process as mundane and at times not engage in the process or utilize feedback provided. This article describes the results of applying audio feedback to overcome these obstacles in a practicum integration course. Student report and assignment performance indicated increased learning and engagement. The instructor found giving audio feedback more efficient than written feedback as it overcame inflection issues associated with the written word. Recorded files also alleviated additional student appointments for clarification of the feedback. PMID:26295848

  18. Using In-class Group Exercises to Enhance Lectures and Provide Introductory Physics Students an Opportunity to Perfect Problem Solving Skills through Interactions with Fellow Students

    Trout, Joseph; Bland, Jared

    2013-03-01

    In this pilot project, one hour of lecture time was replaced with one hour of in-class assignments, which groups of students collaborated on. These in-class assignments consisted of problems or projects selected for the calculus-based introductory physics students The first problem was at a level of difficulty that the majority of the students could complete with a small to moderate amount of difficulty. Each successive problem was increasingly more difficult, the last problem being having a level of difficulty that was beyond the capabilities of the majority of the students and required some instructor intervention. The students were free to choose their own groups. Students were encouraged to interact and help each other understand. The success of the in-class exercises were measured using pre-tests and post-tests. The pre-test and post-test were completed by each student independently. Statistics were also compiled on each student's attendance record and the amount of time spent reading and studying, as reported by the student. Statistics were also completed on the student responses when asked if they had sufficient time to complete the pre-test and post-test and if they would have completed the test with the correct answers if they had more time. The pre-tests and post-tests were not used in the computation of the grades of the students.

  19. My program is ok - am I? Computing freshmen's experiences of doing programming assignments

    Kinnunen, Päivi; Simon, Beth

    2012-03-01

    This article provides insight into how computing majors experience the process of doing programming assignments in their first programming course. This grounded theory study sheds light on the various processes and contexts through which students constantly assess their self-efficacy as a programmer. The data consists of a series of four interviews conducted with a purposeful sample of nine computer science majors in a research intensive state university in the United States. Use of the constant comparative method elicited two forms of results. First, we identified six stages of doing a programming assignment. Analysis captures the dimensional variation in students' experiences with programming assignments on a detailed level. We identified a core category resulting from students' reflected emotions in conjunction with self-efficacy assessment. We provide a descriptive model of how computer science majors build their self-efficacy perceptions, reported via four narratives. Our key findings are that some students reflect negative views of their efficacy, even after having a positive programming experience and that in other situations, students having negative programming experiences still have a positive outlook on their efficacy. We consider these findings in light of possible languages and support structures for introductory programming courses.

  20. Vicious viruses and vigilant vaccines: effects of linguistic agency assignment in health policy advocacy.

    Bell, Robert A; McGlone, Matthew S; Dragojevic, Marko

    2014-01-01

    Studying the effect of a fictitious policy editorial advocating mandatory vaccination of youth against human papillomavirus (HPV), the authors hypothesized that linguistic assignment of agency to HPV (e.g., "HPV preys on millions of people") would increase perceptions of its severity, relative to a comparable message that assigned agency to humans (e.g., "Millions of people contract HPV"). In addition, the authors predicted that HPV vaccines would be perceived as more effective when agency was assigned to vaccination (e.g., "Vaccination guards people") rather than to humans (e.g., "People guard themselves through vaccination"). University students (N = 361) were randomly assigned to read one of four versions of the editorial defined by a 2 ×2 (Threat Agency × Immunization Agency) factorial design and thereafter completed a questionnaire. When agency was assigned to the virus or the vaccine, HPV was perceived as a more severe threat, vaccination was perceived as more effective, and people were more in favor of mandatory HPV vaccination. The authors concluded that linguistic agency assignment bestows potency to the agent, thereby making threats more alarming and medical interventions seem more effective. PMID:24354913

  1. An assignment based distributed resource manager

    Poore, Aubrey B.; Danford, Scott; Hilt, Matthew J.

    2010-04-01

    The goal of this paper is to demonstrate the coordination in real-time of the operation of multiple sensors in such a way that those best-equipped for certain missions should perform those missions for the entire network, while other sensors fill in the gaps with their capabilities. The networked system of sensors must search, detect, track, classify, and engage targets of high value in a timely fashion. The information transmitted should be that which contributes the most toward achieving the performance goals (e.g., track accuracy, track completeness, and a consistent operational picture or single integrated air picture (SIAP)) subject to the network bandwidth constraints and the capabilities of the sensors. We present an overview of an assignment based sensor resource manager, a distributed algorithm for coordinating the assignment problem, and simulation results that validate this approach. While the assignment formulation and algorithms could include both sensor resource and bandwidth constraints with versions for single and multiple time periods, i.e., myopic and non-myopic, the distributed prototype formulation and algorithms developed for these experiments were restricted to the tasking of certain sensors to make measurements and transmit them over the network based on the current air picture. The number of measurements put on the network was controlled by limiting the number of sensors that could transmit measurements on each target. The communication loading was then measured to demonstrate that indeed one can design a distributed sensor resource manager capable of achieving the objectives of significantly reducing the communication loading and maintaining SIAP.

  2. Colony location algorithm for assignment problems

    Dingwei WANG

    2004-01-01

    A novel algorithm called Colony Location Algorithm (CLA) is proposed. It mimics the phenomena in biotic conmunity that colonies of species could be located in the places most suitable to their growth. The factors working on the species location such as the nutrient of soil, resource competition between species, growth and decline process, and effect on environment were considered in CLA via the nutrient function, growth and decline rates, environment evaluation and fertilization strategy.CLA was applied to solve the classical assignment problems. The computation results show that CLA can achieve the optimal solution with higher possibility and shorter running time.

  3. Genetic spectrum assignment model with constraints in cognitive radio networks

    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

  4. Solving Benchmark Frequency Assignment Problem of Helsinki Regions Network by a Novel Nature Inspired Algorithm

    Avtar Singh Buttar

    2013-03-01

    Full Text Available The Frequency Assignment Problem is assignment of frequencies or channels to establish link between base station and mobile transmitter in cellular system. To avoid interference, minimum separation between assigned frequencies is required. This problem is NP-hard. Due to limited availability of spectrum and reuse of same frequencies at different geographical locations, an excellent assignment is to be done, which must satisfy electromagnetic constraints with respect to demand in each cell. This paper presents a novel DGWCHD algorithm for frequency assignment problem in cellular radio networks. The objective is to assign the frequency satisfying electromagnetic constraints for given demand with minimum use of frequency bandwidth. The proposed algorithm is based on real wild animal such as dog’s intelligent strategies during chasing and hunting their prey. The proposed algorithm is implemented on benchmark Kunz’s test problems, which are practical FAP problems based on area around 25 regions in Helsinki, Finland. The DGWCHD algorithm has been used for call ordering and FEA strategy for assignment. The performance of the proposed novel DGWCHD algorithm has been compared with other nature inspired techniques. The results obtained are very optimistic and encouraging

  6. The Perceived Value of College Physics Textbooks: Students and Instructors May Not See Eye to Eye

    Podolefsky, Noah; Finkelstein, Noah

    2006-09-01

    Physics instructors generally tell their students to read the textbook assignments before coming to lecture. While the textbook is a part of nearly every physics course, it is not clear how students use it. Only a small number of previous studies have asked how students actually use their textbooks. One such study measured the amount students read a particular introductory physics textbook at two institutions. This study showed that at one institution less than 40% of students in introductory physics regularly read the textbook assignments, but that at an institution where students were required to submit reading exercises, 55% of students regularly read the textbook. However, this study did not explore the effects of reading or whether different courses or different textbooks affected student reading habits. Another study, in chemistry, reported a significant correlation between the time spent reading and course grades for general chemistry students; lower performing students actually read more. This study, however, also reported that for organic chemistry students there was no correlation between time spent reading and course grades.2

  8. Efficient eigenvalue assignment by state and output feedback with applications for large space structures

    Vannell, Eric C.; Kenny, Sean P.; Maghami, Peiman G.

    1995-01-01

    The erection and deployment of large flexible structures having thousands of degrees of freedom requires controllers based on new techniques of eigenvalue assignment that are computationally stable and more efficient. Scientists at NASA Langley Research Center have developed a novel and efficient algorithm for the eigenvalue assignment of large, time-invariant systems using full-state and output feedback. The objectives of this research were to improve upon the output feedback version of this algorithm, to produce a toolbox of MATLAB functions based on the efficient eigenvalue assignment algorithm, and to experimentally verify the algorithm and software by implementing controllers designed using the MATLAB toolbox on the phase 2 configuration of NASA Langley's controls-structures interaction evolutionary model, a laboratory model used to study space structures. Results from laboratory tests and computer simulations show that effective controllers can be designed using software based on the efficient eigenvalue assignment algorithm.

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

    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

    2002-11-20

    Standard Reference Material (SRM) Baking Chocolate was recently issued, and the process used for value assignment of nutrient concentrations is reported herein. SRM 2384 is intended for use as a primary control material for assigning values to in-house control materials and for validation of analytical methods for the measurement of fatty acids, proximates, vitamins, and elements in chocolate and similar high-fat matrices. The Certificate of Analysis for SRM 2384 provides assigned values for concentrations of fatty acids, proximates, vitamins, elements, and total dietary fiber, for which product labeling is required by the Nutrition Labeling and Education Act of 1990, as well as for catechins, caffeine, theobromine, and theophylline. These assigned values were based on measurements by NIST and/or collaborating laboratories. PMID:12428961

  12. Comprehensive paternity assignment: genotype, spatial location and social status in song sparrows, Melospiza Melodia.

    Sardell, Rebecca J; Keller, Lukas F; Arcese, Peter; Bucher, Thomas; Reid, Jane M

    2010-10-01

    Comprehensive, accurate paternity assignment is critical to answering numerous questions in evolutionary ecology. Yet, most studies of species with extra-pair paternity (EPP) fail to assign sires to all offspring. Common limitations include incomplete and biased sampling of offspring and males, particularly with respect to male location and social status, potentially biasing estimated patterns of paternity. Studies that achieve comprehensive sampling and paternity assignment are therefore required. Accordingly, we genotyped virtually all males and >99% of 6-day-old offspring over 16 years in a song sparrow (Melospiza melodia) population and used three complementary statistical methodologies to attempt complete paternity assignment for all 2207 offspring. Assignments were highly consistent across maximum likelihood methods that used solely genotype data, and heuristic and integrated Bayesian analyses that included data describing individual locations. Sires were assigned to >99% of all genotyped offspring with ≥95% confidence, revealing an EPP rate of c. 28%. Extra-pair sires primarily occupied territories neighbouring their extra-pair offspring; spatial location was therefore highly informative for paternity assignment. EPP was biased towards paired territorial males, although unpaired territorial and floater males sired c. 13% of extra-pair offspring. Failing to sample and include unpaired males as candidate sires would therefore substantially reduce assignment rates. These analyses demonstrate the integration of genetic and ecological information to achieve comprehensive paternity assignment and direct biological insight, illustrate the potential biases that common forms of incomplete sampling could have on estimated patterns of EPP, and provide an essential basis for understanding the evolutionary causes and consequences of EPP.

  14. Algorithms for selecting informative marker panels for population assignment.

    Rosenberg, Noah A

    2005-11-01

    Given a set of potential source populations, genotypes of an individual of unknown origin at a collection of markers can be used to predict the correct source population of the individual. For improved efficiency, informative markers can be chosen from a larger set of markers to maximize the accuracy of this prediction. However, selecting the loci that are individually most informative does not necessarily produce the optimal panel. Here, using genotypes from eight species--carp, cat, chicken, dog, fly, grayling, human, and maize--this univariate accumulation procedure is compared to new multivariate "greedy" and "maximin" algorithms for choosing marker panels. The procedures generally suggest similar panels, although the greedy method often recommends inclusion of loci that are not chosen by the other algorithms. In seven of the eight species, when applied to five or more markers, all methods achieve at least 94% assignment accuracy on simulated individuals, with one species--dog--producing this level of accuracy with only three markers, and the eighth species--human--requiring approximately 13-16 markers. The new algorithms produce substantial improvements over use of randomly selected markers; where differences among the methods are noticeable, the greedy algorithm leads to slightly higher probabilities of correct assignment. Although none of the approaches necessarily chooses the panel with optimal performance, the algorithms all likely select panels with performance near enough to the maximum that they all are suitable for practical use.

  15. Assignment of uncertainties to scientific data

    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.

  16. Diagnosis code assignment: models and evaluation metrics

    Perotte, Adler; Pivovarov, Rimma; Natarajan, Karthik; Weiskopf, Nicole; Wood, Frank; Elhadad, Noémie

    2014-01-01

    Background and objective The volume of healthcare data is growing rapidly with the adoption of health information technology. We focus on automated ICD9 code assignment from discharge summary content and methods for evaluating such assignments. Methods We study ICD9 diagnosis codes and discharge summaries from the publicly available Multiparameter Intelligent Monitoring in Intensive Care II (MIMIC II) repository. We experiment with two coding approaches: one that treats each ICD9 code independently of each other (flat classifier), and one that leverages the hierarchical nature of ICD9 codes into its modeling (hierarchy-based classifier). We propose novel evaluation metrics, which reflect the distances among gold-standard and predicted codes and their locations in the ICD9 tree. Experimental setup, code for modeling, and evaluation scripts are made available to the research community. Results The hierarchy-based classifier outperforms the flat classifier with F-measures of 39.5% and 27.6%, respectively, when trained on 20 533 documents and tested on 2282 documents. While recall is improved at the expense of precision, our novel evaluation metrics show a more refined assessment: for instance, the hierarchy-based classifier identifies the correct sub-tree of gold-standard codes more often than the flat classifier. Error analysis reveals that gold-standard codes are not perfect, and as such the recall and precision are likely underestimated. Conclusions Hierarchy-based classification yields better ICD9 coding than flat classification for MIMIC patients. Automated ICD9 coding is an example of a task for which data and tools can be shared and for which the research community can work together to build on shared models and advance the state of the art.

    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.

  18. System optimal traffic assignment with departure time choice

    Chow, A. H. F.

    2007-01-01

    This thesis investigates analytical dynamic system optimal assignment with departure time choice in a rigorous and original way. Dynamic system optimal assignment is formulated here as a state-dependent optimal control problem. A fixed volume of traffic is assigned to departure times and routes such that the total system travel cost is minimized. Although the system optimal assignment is not a realistic representation of traffic, it provides a bound on performance and shows how...

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

    Chavez, Gregory M [Los Alamos National Laboratory; Booker, Jane M [BOOKER SCIENTIFIC FREDERICKSBURG; Ross, Timothy J [UNM

    2010-10-07

    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.

  6. Dominant pole and eigenstructure assignment for positive systems with state feedback

    Li, Zhao; Lam, James

    2016-09-01

    In this paper, the dominant pole assignment problem, the dominant eigenstructure assignment problem and the robust dominant pole assignment problem for linear time-invariant positive systems with state feedback are considered. The dominant pole assignment problem is formulated as a linear programming problem, and the dominant eigenstructure problem is formulated as a quasiconvex optimisation problem with linear constraints. The robust dominant pole assignment problem is formulated as a non-convex optimisation problem with non-linear constraints which is solved using particle swarm optimisation (PSO) with an efficient scheme which employs the dominant eigenstructure assignment technique to accelerate the convergence of the PSO procedure. Each of the three problems can be further constrained by requiring that the controller has a pre-specified structure, or the gain matrix have both elementwise upper and lower bounds. These constraints can be incorporated into the proposed scheme without increasing the complexity of the algorithms. Both the continuous-time case and the discrete-time case are treated in the paper.

    This paper begins by asking a fundamental question: why do students who take Economics at an introductory level often leave the subject without understanding even the most basic economic principles? The superficial answer seems to be that courses try to cover too many concepts at the expense of mastering the important threshold concepts. Another issue is the way Economics is taught and assessed. I will evaluate an alternative pedagogical device pioneered by Robert Frank: The Economic Naturali...

  8. Optimal Index Assignment for Multiple Description Scalar Quantization

    Zhang, Guoqiang; Kleijn, W Bastiaan

    2011-01-01

    We provide a method for designing an optimal index assignment for scalar K-description coding. The method stems from a construction of translated scalar lattices, which provides a performance advantage by exploiting a so-called staggered gain. Interestingly, generation of the optimal index assignment is based on a lattice in K-1 dimensional space. The use of the K-1 dimensional lattice facilitates analytic insight into the performance and eliminates the need for a greedy optimization of the index assignment. It is shown that that the optimal index assignment is not unique. This is illustrated for the two-description case, where a periodic index assignment is selected from possible optimal assignments and described in detail. The new index assignment is applied to design of a K-description quantizer, which is found to outperform a reference K-description quantizer at high rates. The performance advantage due to the staggered gain increases with increasing redundancy among the descriptions.

  9. Regulatory focus and the assignment of punishment

    Chloe Carmichael

    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.

  12. 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

  15. Towards Automated Structure-Based NMR Resonance Assignment

    Jang, Richard; Gao, Xin; Li, Ming

    We propose a general framework for solving the structure-based NMR backbone resonance assignment problem. The core is a novel 0-1 integer programming model that can start from a complete or partial assignment, generate multiple assignments, and model not only the assignment of spins to residues, but also pairwise dependencies consisting of pairs of spins to pairs of residues. It is still a challenge for automated resonance assignment systems to perform the assignment directly from spectra without any manual intervention. To test the feasibility of this for structure-based assignment, we integrated our system with our automated peak picking and sequence-based resonance assignment system to obtain an assignment for the protein TM1112 with 91% recall and 99% precision without manual intervention. Since using a known structure has the potential to allow one to use only N-labeled NMR data and avoid the added expense of using C-labeled data, we work towards the goal of automated structure-based assignment using only such labeled data. Our system reduced the assignment error of Xiong-Pandurangan-Bailey-Kellogg's contact replacement (CR) method, which to our knowledge is the most error-tolerant method for this problem, by 5 folds on average. By using an iterative algorithm, our system has the added capability of using the NOESY data to correct assignment errors due to errors in predicting the amino acid and secondary structure type of each spin system. On a publicly available data set for Ubiquitin, where the type prediction accuracy is 83%, we achieved 91% assignment accuracy, compared to the 59% accuracy that was obtained without correcting for typing errors.

    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

    2005-01-01

    In this paper we propose a novel Dynamic Bandwidth Assignment (DBA) algorithm for Ethernet-based Passive Optical Networks (EPON) which offers multiple kinds of services. To satisfy crucial Quality of Service (QoS) requirement for Time Division Multiplexing (TDM) service and achieve fair and high bandwidth utilization simultaneously, the algorithm integrates periodic, for TDM service, and polling granting for Ethernet service. Detailed simulation shows that the algorithm guarantees carrier-grade QoS for TDM service, high bandwidth utilization and good fairness of bandwidth assignment among Optical Network Units (ONU).

  19. The Implementation of a New Method of Student Assessment in a Pathogenic Bacteriology Laboratory Course

    M. Frances Hite

    2009-12-01

    Full Text Available 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. In preparing a final assessment for the course, an assignment was developed to challenge the students to apply what they had learned in a medically relevant setting. Also of importance was the elimination of further biochemical testing by these students and prevention of contact with strict pathogens in this lab, due to budget and safety constraints, respectively. Each student was provided with a clinical specimen data record sheet and additional information about their "diseased patient". Students used analytical skills and critical thinking, as well as knowledge gained throughout the semester, to logically deduce the causative agent of disease in the mock patients. Students were required to: (i describe the steps in this logical deduction, (ii provide a brief overview of the characteristics and virulence factors of the organism(s, (iii investigate all disease(s caused by the organism, (iv describe symptomology of the patient in detail, and (v investigate disease treatment and prevention methods. The final assignment involved library and Internet research and culminated in a written report, which further developed writing and communication skills. Detailed descriptions of and materials for this assignment are provided along with an overall evaluation of this method after implementation.

  1. Implementation of an agile maintenance mechanic assignment methodology

    Jimenez, Jesus A.; Quintana, Rolando

    2000-10-01

    The objective of this research was to develop a decision support system (DSS) to study the impact of introducing new equipment into a medical apparel plant from a maintenance organizational structure perspective. This system will enable the company to determine if their capacity is sufficient to meet current maintenance challenges. The DSS contains two database sets that describe equipment and maintenance resource profiles. The equipment profile specifies data such as mean time to failures, mean time to repairs, and minimum mechanic skill level required to fix each machine group. Similarly, maintenance-resource profile reports information about the mechanic staff, such as number and type of certifications received, education level, and experience. The DSS will then use this information to minimize machine downtime by assigning the highest skilled mechanics to machines with higher complexity and product value. A modified version of the simplex method, the transportation problem, was used to perform the optimization. The DSS was built using the Visual Basic for Applications (VBA) language contained in the Microsoft Excel environment. A case study was developed from current existing data. The analysis consisted of forty-two machine groups and six mechanic categories with ten skill levels. Results showed that only 56% of the mechanic workforce was utilized. Thus, the company had available resources for meeting future maintenance requirements.

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

    Cao, Chen; Wang, Guishen; Liu, An; Xu, Shutan; Wang, Lincong; Zou, Shuxue

    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

  10. Linear Assignment Maps for Correlated System-Environment States

    Rodríguez-Rosario, César A; Aspuru-Guzik, Alán

    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.

  18. Embracing different semiotic modes in undergraduate assignments

    Leedham, Maria

    2012-01-01

    The traditional focus within English for Academic Purposes (EAP) teaching of writing in Higher Education is on language produced as linear prose within genres such as the essay, report or case study. While attention is increasingly paid to disciplinary variation and, to a lesser extent, the different range of genres required in assessment, little research has been conducted on additional semiotic modes which may be employed. This paper focuses on resources such as images and layout and the wa...

  19. An Adaptive Strategy for an Optimized Collision-Free Slot Assignment in Multichannel Wireless Sensor Networks

    Pascale Minet

    2013-07-01

    Full Text Available Convergecast is the transmission paradigm used by data gathering applications in wireless sensor networks (WSNs. For efficiency reasons, a collision-free slotted medium access is typically used: time slots are assigned to non-conflicting transmitters. Furthermore, in any slot, only the transmitters and the corresponding receivers are awake, the other nodes sleeping in order to save energy. Since a multichannel network increases the throughput available to the application and reduces interference, multichannel slot assignment is an emerging research domain in WSNs. First, we focus on a multichannel time slot assignment that minimizes the data gathering delays. We compute the optimal time needed for a raw data convergecast in various multichannel topologies. Then, we focus on how to adapt such an assignment to dynamic demands of transmissions (e.g., alarms, temporary additional application needs and retransmissions. We formalize the problem using linear programming, and we propose an incremental technique that operates on an optimized primary schedule to provide bonus slots to meet new transmission needs. We propose AMSA, an Adaptive Multichannel Slot Assignment algorithm, which takes advantage of bandwidth spatial reuse, and we evaluate its performances in terms of the number of slots required, slot reuse, throughput and the number of radio state switches.

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

    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

  1. Student-Designed Service-Learning Projects in an Undergraduate Neurobiology Course

    Katharine V. Northcutt

    2015-12-01

    Full Text Available One of the challenges in teaching a service-learning course is obtaining student buy-in from all students in the course. To circumvent this problem, I have let students in my undergraduate Neurobiology course design their own service-learning projects at the beginning of the semester. Although this can be chaotic because it requires last-minute planning, I have made it successful through facilitating student communication in the classroom, requiring thorough project proposals, meeting with students regularly, and monitoring group progress through written reflection papers. Most of my students have strong opinions about the types of projects that they want to carry out, and many students have used connections that they have already made with local organizations. Almost all projects that students have designed to this point involve teaching basic concepts of neurobiology to children of various ages while simultaneously sparking their interest in science. Through taking ownership of the project and designing it such that it works well with their strengths, interests, and weekly schedule, students have become more engaged in service learning and view it as a valuable experience. Despite some class time being shifted away from more traditional assignments, students have performed equally well in the course, and they are more eager to talk with others about course concepts. Furthermore, the feedback that I have received from community partners has been excellent, and some students have maintained their work with the organizations.

  16. New Channel Assignment Method for Access Points in Wireless LANs

    Mohammed Fawzi Al-Hunaity

    2011-11-01

    Full Text Available Wireless LANs topology communicates using radio frequencies. The number of these frequencies is limited and not enough to assign a special frequency for each Access Point, this means that the communication topology should use a e-use mechanism, which allows the system to assign the same frequency that assigned previously for another access point. In this paper, we suggest a method to assign frequency channels to access points in a Wireless LANs system. The goal of this paper is to reach the assignment that prevents interference between access points especially neighbor ones. We used Genetic Algorithm to work on this issue, it is considered as an Expert System and one of the main multi point search technique used in computing to solve optimization and search problems.

  17. Fast assignment reduction in inconsistent incomplete decision systems

    Min Li; Shaobo Deng; Shengzhong Feng; Jianping Fan

    2014-01-01

    This paper focuses on fast algorithm for computing the assignment reduct in inconsistent incomplete decision systems. It is quite inconvenient to judge the assignment reduct directly ac-cording to its definition. We propose the judgment theorem for the assignment reduct in the inconsistent incomplete decision system, which greatly simplifies judging this type reduct. On such basis, we derive a novel attribute significance measure and construct the fast assignment reduction algorithm (F-ARA), intended for com-puting the assignment reduct in inconsistent incomplete decision systems. Final y, we make a comparison between F-ARA and the discernibility matrix-based method by experiments on 13 Univer-sity of California at Irvine (UCI) datasets, and the experimental results prove that F-ARA is efficient and feasible.

    2013-01-01

    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.

  19. A New Approach to Pointer Analysis for Assignments

    HUANG Bo; ZANG Binyu; LI Jing; ZHU Chuanqi

    2001-01-01

    Pointer analysis is a technique to identify at compile-time the po tential values of the pointer expressions in a program, which promises significant benefits for optimizing and parallelizing compilers. In this paper, a new approach to pointer analysis for assignments is presented. In this approach, assignments are clas sified into three categories: pointer assignments, structure (union) assignments and normal assignments which don't affect the point-to information. Pointer analyses for these three kinds of assignments respectively make up the integrated algorithm. When analyzing a pointer assignment, a new method called expression expansion is used to calculate both the left targets and the right targets. The integration of recursive data structure analysis into pointer analysis is a significant originality of this paper, which uniforms the pointer analysis for heap variables and the pointer analysis for stack variables. This algorithm is implemented in Agassiz, an analyzing tool for C programs developed by Institute of Parallel Processing, Fudan University. Its accuracy and effectiveness are illustrated by experimental data.

  20. Localized Algorithm for Channel Assignment in Cognitive Radio Networks

    Harpreet Kaur

    2015-12-01

    Full Text Available Cognitive Radio has been emerged as a revolutionary solution to migrate the current shortage of spectrum allocation in wireless networks. In this paper, an improved localized channel allocation algorithm based on channel weight is proposed. A factor of channel stability is introduced based on link environment, which efficiently assigns the best channels to the links. Based on the framework, a conflict resolution strategy is used to make the scheme adaptable to different network conditions. Calculations indicate that this algorithm can reduce the conflicts, increase the delivery rate and link assignment rate compared with the basic channel assignment algorithm.

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

    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.

  2. Graphical interpretation of Boolean operators for protein NMR assignments.

    Verdegem, Dries; Dijkstra, Klaas; Hanoulle, Xavier; Lippens, Guy

    2008-09-01

    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. PMID:18762868

    Johnson, R; Johnson, D W; DeWeerdt, N; Lyons, V; Zaidman, B

    1983-05-01

    The effects of cooperative and individualistic learning experiences were compared on interactions and relationships between severely adaptive handicapped (not adapting to regular classroom demands) and nonhandicapped seventh-grade students in science classes. We investigated the predictions that (a) requiring cooperation between the two groups of students would result in increased rejection of the severely adaptive handicapped students and (b) cooperation would promote increased interpersonal attraction regardless of the heterogeneity of the students. Forty-eight suburban junior-high-school, seventh-grade students (41 nonhandicapped, 9 severely adaptive handicapped) were assigned to conditions on a stratified random basis controlling for handicap, sex, and ability level. They participated in the study for 10 days, 55 minutes per day. Results indicated that cooperative learning procedures, compared with individualistic ones, promoted more interaction and interpersonal attraction between severely adaptive handicapped and nonhandicapped students.

    2007-12-01

    The Just-in-Time Teaching (JiTT) technique allows students to be engaged in course material outside of the classroom by answering web-based questions. The responses are summarized and presented to students in class with a follow-up active learning exercise. College students enrolled in an introductory-level general education geoscience course were surveyed over a two-semester period on their engagement level during lecture and perceived learning of course content. Data show that students are able to reflect on their prior knowledge and construct new knowledge with weekly graded JiTT exercises. Despite increasing and competing pressures outside of the classroom, students reported increased learning and engagement in a course with required weekly assignments.

  12. Subcarrier Group Assignment for MC-CDMA Wireless Networks

    Tho Le-Ngoc

    2007-12-01

    Full Text Available Two interference-based subcarrier group assignment strategies in dynamic resource allocation are proposed for MC-CDMA wireless systems to achieve high throughput in a multicell environment. Least interfered group assignment (LIGA selects for each session the subcarrier group on which the user receives the minimum interference, while best channel ratio group assignment (BCRGA chooses the subcarrier group with the largest channel response-to-interference ratio. Both analytical framework and simulation model are developed for evaluation of throughput distribution of the proposed schemes. An iterative approach is devised to handle the complex interdependency between multicell interference profiles in the throughput analysis. Illustrative results show significant throughput improvement offered by the interference-based assignment schemes for MC-CDMA multicell wireless systems. In particular, under low loading conditions, LIGA renders the best performance. However, as the load increases BCRGA tends to offer superior performance.

  14. An Improved Point-track Optimal Assignment Algorithm

    Zhonglei Zhang

    2013-12-01

    Full Text Available In order to improve the accuracy of data association of the Optimal Assignment (OA algorithm based on dynamic information, an improved Point-Track Optimal Assignment (IPTOA algorithm based on multi-source information is proposed. The improved algorithm gets valid 3-tuple of measurement set by solving 3-Dimensional (3-D assignment problem which is based on dynamic information. Then fuses multi-source information by combination rule of D-S evidence theory and constructs the point-track correlation matrix between valid 3-tuple of measurement and target track. Compared with the optimal assignment algorithm based on dynamic information, the new algorithm effectively fuses multi-source information to correlate measurement data, which improves the performance of multi-target tracking in different degrees. Simulation results verify the feasibility and effectiveness of the new algorithm.

    2016-01-01

    Managing radio spectrum resources is a crucial issue. The frequency assignment problem (FAP) basically aims to allocate, in an efficient manner, limited number of frequencies to communication links. Geographically close links, however, cause interference, which complicates the assignment, imposing frequency separation constraints. The FAP is closely related to the graph-coloring problem and it is an NP-hard problem. In this paper, we propose to incorporate the randomization into greedy and fa...

    Day-to-Day and Within-Day dynamics are classically observed in dynamic traffic assignment, but smaller ones due to traffic lights phases also occur. These micro variations induce flow fluctuations defined at a cycle time scale. Their precise knowledge is irrelevant in a dynamic traffic assignment context. We propose to integrate these micro dynamics into a new intersection model without stages in which their average effects must be taken into account, especially delay and flow restriction ge...

  18. Context-Aware Reviewer Assignment for Trust Enhanced Peer Review.

    Lei Li

    Full Text Available Reviewer assignment is critical to peer review systems, such as peer-reviewed research conferences or peer-reviewed funding applications, and its effectiveness is a deep concern of all academics. However, there are some problems in existing peer review systems during reviewer assignment. For example, some of the reviewers are much more stringent than others, leading to an unfair final decision, i.e., some submissions (i.e., papers or applications with better quality are rejected. In this paper, we propose a context-aware reviewer assignment for trust enhanced peer review. More specifically, in our approach, we first consider the research area specific expertise of reviewers, and the institution relevance and co-authorship between reviewers and authors, so that reviewers with the right expertise are assigned to the corresponding submissions without potential conflict of interest. In addition, we propose a novel cross-assignment paradigm, and reviewers are cross-assigned in order to avoid assigning a group of stringent reviewers or a group of lenient reviewers to the same submission. More importantly, on top of them, we propose an academic CONtext-aware expertise relevanCe oriEnted Reviewer cross-assignmenT approach (CONCERT, which aims to effectively estimate the "true" ratings of submissions based on the ratings from all reviewers, even though no prior knowledge exists about the distribution of stringent reviewers and lenient reviewers. The experiments illustrate that compared with existing approaches, our proposed CONCERT approach can less likely assign more than one stringent reviewers or lenient reviewers to a submission simultaneously and significantly reduce the influence of ratings from stringent reviewers and lenient reviewers, leading to trust enhanced peer review and selection, no matter what kind of distributions of stringent reviewers and lenient reviewers are.

    2000-01-01

    Dynamic traffic assignment is widely recognised as being more useful to evaluate traffic management measures than is static counterpart, as it allows us to analyse how congestion forms and dissipates in time-varying conditions. In this thesis, both deterministic and stochastic dynamic assignments are modelled with a proper link performance function, and solved with efficient solution algorithms so that they give rise to high quality solutions. A deterministic dynamic assignm...

  4. Comparison of Memory Assignment Schemes for Switch Architectures with Shareable Parallel Memory Modules

    Sanjeev Kumar

    2010-01-01

    Full Text Available Switching Architectures deploying shareable parallel memory modules are quite versatile in their ability to scale to higher capacity while retaining the advantage of sharing its entire memory resource among all input and output ports. The two main classes of such architectures, namely, the Shared Multibuffer-(SMB- based switch and the Sliding-Window-(SW- based packet switch, both deploy parallel memory modules that are physically separate but logically connected. Inspite of their similarity in regards to using shareable parallel memory modules, they differ in switching control and scheduling of packets to parallel memory modules. SMB switch uses centralized control whereas the SW switch uses a decentralized control for switching operations. In this paper, we present a new memory assignment scheme for the Sliding-Window (SW switch for assigning packets to parallel memory modules that maximizes the parallel storage of packets to multiple memory modules. We compare the performance of a sliding-window switch deploying this new memory assignment scheme with that of an SMB switch architecture under conditions of identical traffic type and memory resources deployed. The simulation results show that the new memory assignment scheme for the sliding window switch maximizes parallel storage of packets input in a given switch cycle, and it does not require speed-up of memory modules. Furthermore, it provides a superior performance compared to that of the SMB switch under the constraints of fixed memory-bandwidth and memory resources.

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

    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.

  6. 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 CHβ assignments. For the 128 residue long azurin, missing assignments mostly affect Hα and Hβ. Among the remaining backbone (plus Cβ) 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 CHβresonances 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.

  7. Exploiting image registration for automated resonance assignment in NMR

    Analysis of protein NMR data involves the assignment of resonance peaks in a number of multidimensional data sets. To establish resonance assignment a three-dimensional search is used to match a pair of common variables, such as chemical shifts of the same spin system, in different NMR spectra. We show that by displaying the variables to be compared in two-dimensional plots the process can be simplified. Moreover, by utilizing a fast Fourier transform cross-correlation algorithm, more common to the field of image registration or pattern matching, we can automate this process. Here, we use sequential NMR backbone assignment as an example to show that the combination of correlation plots and segmented pattern matching establishes fast backbone assignment in fifteen proteins of varying sizes. For example, the 265-residue RalBP1 protein was 95.4 % correctly assigned in 10 s. The same concept can be applied to any multidimensional NMR data set where analysis comprises the comparison of two variables. This modular and robust approach offers high efficiency with excellent computational scalability and could be easily incorporated into existing assignment software

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

    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. Developing a Research Tool to Gauge Student Metacognition

    McInerny, Alistair; Boudreaux, Andrew; Rishal, Sepideh; Clare, Kelci

    2012-10-01

    Metacognition refers to the family of thought processes and skills used to evaluate and manage learning. A research and curriculum development project underway at Western Washington University uses introductory physics labs as a context to promote students' abilities to learn and apply metacognitive skills. A required ``narrative reflection'' has been incorporated as a weekly end-of-lab assignment. The goal of the narrative reflection is to encourage and support student metacognition while generating written artifacts that can be used by researchers to study metacognition in action. We have developed a Reflective Thinking Rubric (RTR) to analyze scanned narrative reflections. The RTR codes student writing for Metacognitive Elements, identifiable steps or aspects of metacognitive thinking at a variety of levels of sophistication. We hope to use the RTR to monitor the effect of weekly reflection on metacognitive ability and to search for correlations between metacognitive ability and conceptual understanding.

  2. A Bayesian Assignment Method for Ambiguous Bisulfite Short Reads.

    Hong Tran

    Full Text Available DNA methylation is an epigenetic modification critical for normal development and diseases. The determination of genome-wide DNA methylation at single-nucleotide resolution is made possible by sequencing bisulfite treated DNA with next generation high-throughput sequencing. However, aligning bisulfite short reads to a reference genome remains challenging as only a limited proportion of them (around 50-70% can be aligned uniquely; a significant proportion, known as multireads, are mapped to multiple locations and thus discarded from downstream analyses, causing financial waste and biased methylation inference. To address this issue, we develop a Bayesian model that assigns multireads to their most likely locations based on the posterior probability derived from information hidden in uniquely aligned reads. Analyses of both simulated data and real hairpin bisulfite sequencing data show that our method can effectively assign approximately 70% of the multireads to their best locations with up to 90% accuracy, leading to a significant increase in the overall mapping efficiency. Moreover, the assignment model shows robust performance with low coverage depth, making it particularly attractive considering the prohibitive cost of bisulfite sequencing. Additionally, results show that longer reads help improve the performance of the assignment model. The assignment model is also robust to varying degrees of methylation and varying sequencing error rates. Finally, incorporating prior knowledge on mutation rate and context specific methylation level into the assignment model increases inference accuracy. The assignment model is implemented in the BAM-ABS package and freely available at https://github.com/zhanglabvt/BAM_ABS.

  4. A high throughput single nucleotide polymorphism multiplex assay for parentage assignment in New Zealand sheep.

    Shannon M Clarke

    Full Text Available Accurate pedigree information is critical to animal breeding systems to ensure the highest rate of genetic gain and management of inbreeding. The abundance of available genomic data, together with development of high throughput genotyping platforms, means that single nucleotide polymorphisms (SNPs are now the DNA marker of choice for genomic selection studies. Furthermore the superior qualities of SNPs compared to microsatellite markers allows for standardization between laboratories; a property that is crucial for developing an international set of markers for traceability studies. The objective of this study was to develop a high throughput SNP assay for use in the New Zealand sheep industry that gives accurate pedigree assignment and will allow a reduction in breeder input over lambing. This required two phases of development--firstly, a method of extracting quality DNA from ear-punch tissue performed in a high throughput cost efficient manner and secondly a SNP assay that has the ability to assign paternity to progeny resulting from mob mating. A likelihood based approach to infer paternity was used where sires with the highest LOD score (log of the ratio of the likelihood given parentage to likelihood given non-parentage are assigned. An 84 "parentage SNP panel" was developed that assigned, on average, 99% of progeny to a sire in a problem where there were 3,000 progeny from 120 mob mated sires that included numerous half sib sires. In only 6% of those cases was there another sire with at least a 0.02 probability of paternity. Furthermore dam information (either recorded, or by genotyping possible dams was absent, highlighting the SNP test's suitability for paternity testing. Utilization of this parentage SNP assay will allow implementation of progeny testing into large commercial farms where the improved accuracy of sire assignment and genetic evaluations will increase genetic gain in the sheep industry.

  5. A spectroscopic assignment technique for membrane proteins reconstituted in magnetically aligned bicelles

    Oriented-sample NMR (OS-NMR) has emerged as a powerful tool for the structure determination of membrane proteins in their physiological environments. However, the traditional spectroscopic assignment method in OS NMR that uses the “shotgun” approach, though effective, is quite labor- and time-consuming as it is based on the preparation of multiple selectively labeled samples. Here we demonstrate that, by using a combination of the spin exchange under mismatched Hartmann-Hahn conditions and a recent sensitivity-enhancement REP-CP sequence, spectroscopic assignment of solid-state NMR spectra of Pf1 coat protein reconstituted in magnetically aligned bicelles can be significantly improved. This method yields a two-dimensional spin-exchanged version of the SAMPI4 spectrum correlating the 15N chemical shift and 15N–1H dipolar couplings, as well as spin-correlations between the (i, i ± 1) amide sites. Combining the spin-exchanged SAMPI4 spectrum with the original SAMPI4 experiment makes it possible to establish sequential assignments, and this technique is generally applicable to other uniaxially aligned membrane proteins. Inclusion of an 15N–15N correlation spectrum into the assignment process helps establish correlations between the peaks in crowded or ambiguous spectral regions of the spin-exchanged SAMPI4 experiment. Notably, unlike the traditional method, only a uniformly labeled protein sample is required for spectroscopic assignment with perhaps only a few selectively labeled “seed” spectra. Simulations for the magnetization transfer between the dilute spins under mismatched Hartmann Hahn conditions for various B1 fields have also been performed. The results adequately describe the optimal conditions for establishing the cross peaks, thus eliminating the need for lengthy experimental optimizations.

  6. RNA-PAIRS: RNA probabilistic assignment of imino resonance shifts

    Bahrami, Arash; Clos, Lawrence J.; Markley, John L.; Butcher, Samuel E. [National Magnetic Resonance Facility at Madison (United States); Eghbalnia, Hamid R., E-mail: eghbalhd@uc.edu [University of Cincinnati, Department of Molecular and Cellular Physiology (United States)

    2012-04-15

    The significant biological role of RNA has further highlighted the need for improving the accuracy, efficiency and the reach of methods for investigating RNA structure and function. Nuclear magnetic resonance (NMR) spectroscopy is vital to furthering the goals of RNA structural biology because of its distinctive capabilities. However, the dispersion pattern in the NMR spectra of RNA makes automated resonance assignment, a key step in NMR investigation of biomolecules, remarkably challenging. Herein we present RNA Probabilistic Assignment of Imino Resonance Shifts (RNA-PAIRS), a method for the automated assignment of RNA imino resonances with synchronized verification and correction of predicted secondary structure. RNA-PAIRS represents an advance in modeling the assignment paradigm because it seeds the probabilistic network for assignment with experimental NMR data, and predicted RNA secondary structure, simultaneously and from the start. Subsequently, RNA-PAIRS sets in motion a dynamic network that reverberates between predictions and experimental evidence in order to reconcile and rectify resonance assignments and secondary structure information. The procedure is halted when assignments and base-parings are deemed to be most consistent with observed crosspeaks. The current implementation of RNA-PAIRS uses an initial peak list derived from proton-nitrogen heteronuclear multiple quantum correlation ({sup 1}H-{sup 15}N 2D HMQC) and proton-proton nuclear Overhauser enhancement spectroscopy ({sup 1}H-{sup 1}H 2D NOESY) experiments. We have evaluated the performance of RNA-PAIRS by using it to analyze NMR datasets from 26 previously studied RNAs, including a 111-nucleotide complex. For moderately sized RNA molecules, and over a range of comparatively complex structural motifs, the average assignment accuracy exceeds 90%, while the average base pair prediction accuracy exceeded 93%. RNA-PAIRS yielded accurate assignments and base pairings consistent with imino

  7. Compatibility of state assignments and pooling of information

    Brun, Todd A.; Hsieh, Min-Hsiu; Perry, Christopher

    2015-07-01

    We say that two (or more) state assignments for one and the same quantum system are compatible if they could represent the assignments of observers with differing information about the system. A criterion for compatibility was proposed in [Phys. Rev. A 65, 032315 (2002), 10.1103/PhysRevA.65.032315]; however, this leaves unanswered the question of whether there are degrees of compatibility which could be represented by some quantitative measure, and whether there is a straightforward procedure whereby the observers can pool their information to arrive at a unique joint state assignment. We argue that such measures are only sensible given some assumption about what kind of information was used in making the state assignments in the first place, and that in general state assignments do not represent all of the information possessed by the observers. However, we examine one particular measure and show that it has a straightforward interpretation, assuming that the information was acquired from a particular type of measurement, and that in this case there is a natural rule for pooling information. We extend this measure to compatibility of states for k observers and show that the value is the solution to a semidefinite program. Similar compatibility measures can be defined for alternative notions of state compatibility, including post-Peierls and equal support compatibilities.

  8. Reflective practice: assessment of assignments in English for Specific Purposes

    Galina Kavaliauskiené

    2007-10-01

    Full Text Available The construct alternative assessment has been widely used in higher education. It is often defined as any type of assessment of learners who provide a response to an assignment. The key features of alternative assessment are active participation of learners in self-evaluation of their performance, and the development of reflective thinking through reflective thinking (Schön, 1983. The success of alternative assessment in language teaching is predetermined by student’s performance and demonstrates learner’s language proficiency in contemporary communicative classrooms. This paper aims at researching the influence of students’ evaluations of various assignments for their linguistic development in English for Specific Purposes (ESP. The study uses learners’ assessment of different assignments and learners’ in-course and post-course written reflections on benefits to language mastery. Learners’ assignments included were contributions to portfolios (dossiers, such as essays and summaries, oral presentations, short impromptu talks, creative tasks, tests, and self-assessment notes (reflections on activities in learning ESP. Findings were obtained for two streams of the project participants. Results showed that self-assessment was beneficial for learners’ linguistic development. The context of learners’ reflections reveals that the attitudes to various assignments are affected by success or failure in students’ performance. Reflective practice might help teachers develop ways of dealing with previously identified difficulties and improve the quality of teaching.

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

    Brassell, S. C.

    2014-12-01

    "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.

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

    Toru Tamaki

    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.

  17. Complete sequence-specific 1H NMR assignments for human insulin

    Solvent conditions where human insulin could be studied by high-resolution NMR were determined. Both low pH and addition of acetonitrile were required to overcome the protein's self-association and to obtain useful spectra. Two hundred eighty-six 1H resonances were located and assigned to specific sites on the protein by using two-dimensional NMR methods. The presence and position of numerous dNN sequential NOE's indicate that the insulin conformation seen in crystallographic studies is largely retained under these solution conditions. Slowly exchanging protons were observed for seven backbone amide protons and were assigned to positions A15 and A16 and to positions B15-B19. These amides all occur within helical regions of the protein

  19. Protein residue linking in a single spectrum for magic-angle spinning NMR assignment

    Here we introduce a new pulse sequence for resonance assignment that halves the number of data sets required for sequential linking by directly correlating sequential amide resonances in a single diagonal-free spectrum. The method is demonstrated with both microcrystalline and sedimented deuterated proteins spinning at 60 and 111 kHz, and a fully protonated microcrystalline protein spinning at 111 kHz, with as little as 0.5 mg protein sample. We find that amide signals have a low chance of ambiguous linkage, which is further improved by linking in both forward and backward directions.

    The present study presents and discusses the conformational preferences of Norspermidine (NSpd). The effects of varying the dielectric constant on the conformational preferences are discussed, with a view to infer which conformation will correspond to the most stable in the pure condensed liquid phase. Within the same context, a set of NSpd-NH3 molecular adducts were simulated in order to determine the relevance of intermolecular hydrogen bonding on the overall stability and relative positioning of the respective vibrational frequencies. The calculations presently performed allowed a reassessment of the vibrational assignments for NSpd. A full assignment of the NSpd vibrational spectra is presented, with special emphasis being given to the vibrational modes that proved to be most affected by hydrogen bonding. The various inconsistencies of a prior study found in the literature were identified and rectified. An incorrect description of the molecular structure and/or electronic distribution will lead to erroneous forecasts of the vibrational frequencies, culminating in inaccurate assignments.

  1. A Stone Resource Assignment Model under the Fuzzy Environment

    Liming Yao

    2012-01-01

    to tackle a stone resource assignment problem with the aim of decreasing dust and waste water emissions. On the upper level, the local government wants to assign a reasonable exploitation amount to each stone plant so as to minimize total emissions and maximize employment and economic profit. On the lower level, stone plants must reasonably assign stone resources to produce different stone products under the exploitation constraint. To deal with inherent uncertainties, the object functions and constraints are defuzzified using a possibility measure. A fuzzy simulation-based improved simulated annealing algorithm (FS-ISA is designed to search for the Pareto optimal solutions. Finally, a case study is presented to demonstrate the practicality and efficiency of the model. Results and a comparison analysis are presented to highlight the performance of the optimization method, which proves to be very efficient compared with other algorithms.

  2. Assigning on-ramp flows to maximize highway capacity

    In this paper, we study the capacity of a highway with two on-ramps by using a cellular automata traffic flow model. We investigate how to improve the system capacity by assigning traffic flow to the two ramps. The system phase diagram is presented and different regions are classified. It is shown that in region I, in which both ramps are in free flow and the main road upstream of the ramps is in congestion, assigning a higher proportion of the demand to the upstream on-ramp could improve the overall flow, which is consistent with previous studies. This is explained through studying the spatiotemporal patterns and analytical investigations. In contrast, optimal assignment has not been observed in other regions. We point out that our result is robust and model independent under certain conditions.

  3. Lexical stress assignment as a problem of probabilistic inference.

    Jouravlev, Olessia; Lupker, Stephen J

    2015-10-01

    A new conceptualization of the process of stress assignment, couched in the principles of (Bayesian) probabilistic inference, is introduced in this paper. According to this approach, in deciding where to place stress in a polysyllabic word, a reader estimates the posterior probabilities of alternative stress patterns. This estimation is accomplished by adjusting a prior belief about the likelihoods of alternative stress patterns (derived from experience with the distribution of stress patterns in the language) by using lexical and non-lexical sources of evidence for stress derived from the orthographic input. The proposed theoretical framework was used to compute probabilities of stress patterns for Russian disyllabic words and nonwords which were then compared with the performance of readers. The results showed that the estimated probabilities of stress patterns were reflective of actual stress assignment performance and of naming latencies, suggesting that the mechanisms that are involved in the process of stress assignment might indeed be inferentially-based.

  4. Complexity and Approximation of a Geometric Local Robot Assignment Problem

    Bonorden, Olaf; Degener, Bastian; Kempkes, Barbara; Pietrzyk, Peter

    We introduce a geometric multi-robot assignment problem. Robots positioned in a Euclidean space have to be assigned to treasures in such a way that their joint strength is sufficient to unearth a treasure with a given weight. The robots have a limited range and thus can only be assigned to treasures in their proximity. The objective is to unearth as many treasures as possible. We investigate the complexity of several variants of this problem and show whether they are in {mathcal P} or are mathcal{ NP}-complete. Furthermore, we provide a distributed and local constant-factor approximation algorithm using constant-factor resource augmentation for the two-dimensional setting with {mathcal O}(log^*n) communication rounds.

  5. Task Assignment Heuristics for Parallel and Distributed CFD Applications

    Lopez-Benitez, Noe; Djomehri, M. Jahed; Biswas, Rupak

    2003-01-01

    This paper proposes a task graph (TG) model to represent a single discrete step of multi-block overset grid computational fluid dynamics (CFD) applications. The TG model is then used to not only balance the computational workload across the overset grids but also to reduce inter-grid communication costs. We have developed a set of task assignment heuristics based on the constraints inherent in this class of CFD problems. Two basic assignments, the smallest task first (STF) and the largest task first (LTF), are first presented. They are then systematically costs. To predict the performance of the proposed task assignment heuristics, extensive performance evaluations are conducted on a synthetic TG with tasks defined in terms of the number of grid points in predetermined overlapping grids. A TG derived from a realistic problem with eight million grid points is also used as a test case.

    Sommerville, I.; Lock, R.; Storer, T.

    2012-01-01

    In this paper, we discuss an approach to system requirements engineering, which is based on using models of the responsibilities assigned to agents in a multi-agency system of systems. The responsibility models serve as a basis for identifying the stakeholders that should be considered in establishing the requirements and provide a basis for a structured approach, described here, for information requirements elicitation. We illustrate this approach using a case study drawn from civil emergenc...

    The automated assignment of NOESY cross peaks has become a fundamental technique for NMR protein structure analysis. A widely used algorithm for this purpose is implemented in the program CYANA. It has been used for a large number of structure determinations of proteins in solution but was so far not described in full detail. In this paper we present a complete description of the CYANA implementation of automated NOESY assignment, which differs extensively from its predecessor CANDID by the use of a consistent probabilistic treatment, and we discuss its performance in the second round of the critical assessment of structure determination by NMR.

  13. Probabilistic validation of protein NMR chemical shift assignments

    Data validation plays an important role in ensuring the reliability and reproducibility of studies. NMR investigations of the functional properties, dynamics, chemical kinetics, and structures of proteins depend critically on the correctness of chemical shift assignments. We present a novel probabilistic method named ARECA for validating chemical shift assignments that relies on the nuclear Overhauser effect data. ARECA has been evaluated through its application to 26 case studies and has been shown to be complementary to, and usually more reliable than, approaches based on chemical shift databases. ARECA is available online at http://areca.nmrfam.wisc.edu/ http://areca.nmrfam.wisc.edu/

  15. A tracked approach for automated NMR assignments in proteins (TATAPRO)

    A novel automated approach for the sequence specific NMR assignments of 1HN, 13Cα, 13Cβ, 13C'/1Hα and 15N spins in proteins, using triple resonance experimental data, is presented. The algorithm, TATAPRO (Tracked AuTomated Assignments in Proteins) utilizes the protein primary sequence and peak lists from a set of triple resonance spectra which correlate 1HN and 15N chemical shifts with those of 13Cα, 13Cβ and 13C'/1Hα. The information derived from such correlations is used to create a 'masterlist' consisting of all possible sets of 1HNi, 15Ni, 13Cαi, 13Cβi, 13C'i/1Hαi, 13Cαi-1, 13Cβi-1 and 13C'i-1/ 1Hαi-1 chemical shifts. On the basis of an extensive statistical analysis of 13Cα and 13Cβ chemical shift data of proteins derived from the BioMagResBank (BMRB), it is shown that the 20 amino acid residues can be grouped into eight distinct categories, each of which is assigned a unique two-digit code. Such a code is used to tag individual sets of chemical shifts in the masterlist and also to translate the protein primary sequence into an array called ppsarray. The program then uses the masterlist to search for neighbouring partners of a given amino acid residue along the polypeptide chain and sequentially assigns a maximum possible stretch of residues on either side. While doing so, each assigned residue is tracked in an array called assigarray, with the two-digit code assigned earlier. The assigarray is then mapped onto the ppsarray for sequence specific resonance assignment. The program has been tested using experimental data on a calcium binding protein from Entamoeba histolytica (Eh-CaBP, 15 kDa) having substantial internal sequence homology and using published data on four other proteins in the molecular weight range of 18-42 kDa. In all the cases, nearly complete sequence specific resonance assignments (> 95%) are obtained. Furthermore, the reliability of the program has been tested by deleting sets of chemical shifts randomly from the masterlist

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

    Enrique de la Hoz

    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.

  18. 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.
