    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.

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

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

    Directory of Open Access Journals (Sweden)

    Ivo Beroš

    2015-10-01

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

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

    Directory of Open Access Journals (Sweden)

    Bilge Gokhan Celik

    2013-06-01

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

  13. Marmoset: A programming project assignment framework to improve the feedback cycle for students, faculty and researchers

    Science.gov (United States)

    Spacco, Jaime W.

    We developed Marmoset, a system that improves the feedback cycle on programming assignments for students, faculty and researchers alike. Using automation, Marmoset substantially lowers the burden on faculty for grading programming assignments, allowing faculty to give students more rapid feedback on their assignments. To further improve the feedback cycle, Marmoset provides students with limited access to the results of the instructor's private test cases before the submission deadline using a novel token-based incentive system. This both encourages students to start their work early and to think critically about their work. Because students submit early, instructors can monitor all students' progress on test cases and identify where in projects students are having problems in order to update the project requirements in a timely fashion and make the best use of time in lectures, discussion sections, and office hours. To study in more detail the development process of students, Marmoset can be configured to transparently capture snapshots to a central repository every-time students save their files. These detailed development histories offer a unique, detailed perspective of each student's progress on a programming assignment, from the first line of code written and saved all the way through the final edit before the final submission. This type of data has proved extremely valuable for many uses, such as mining new bug patterns and evaluating existing bug-finding tools.

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

    Science.gov (United States)

    Harbor, Jon

    2014-05-01

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

  20. 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.

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

    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.

    2011-12-01

    Nursing students need the necessary resources to successfully complete a professional paper writing assignment. The purpose of this article is to describe resource support and evaluation strategies used in a professional paper writing assignment in a baccalaureate nursing program. The impetus for the study is to address the need for nursing faculty to move students toward writing proficiency while improving their information management skills. Students need resources to successfully complete professional papers due to the need for mining relevant professional sources, assistance with editing, and refinement of paper gained through peer feedback. Methods include evaluation of the interdisciplinary resource collaboration with campus librarians (information literacy), campus writing center tutorial oversight, and peer reviewer support and feedback. Student evaluation of the teaching strategy found the resources helpful for completion of the writing assignment and the collaborative learning with campus colleagues and writing experts beneficial.

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

    Directory of Open Access Journals (Sweden)

    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.

  9. 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.

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

    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

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

    Science.gov (United States)

    Sturdivant Allen, Anita Kay

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

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

    Science.gov (United States)

    Serder, Margareta; Jakobsson, Anders

    2015-09-01

    Large-scale assessment, such as the Programme for International Assessment (PISA), plays an increasingly important role in current educational practice and politics. However, many scholars have questioned the validity and reliability of the tests and the extent to which they actually constitute trustworthy representations of students' knowledge. In the light of such critical voices the present article adopts a sociocultural perspective of human knowledge and action in order to explore the encounters between students and the science test assignments with which their knowledge is tested. Of particular interest in this study are the described "real-life situations" presented as the relevant background in which scientific literacy is assessed in PISA. According to the sociocultural theoretical onset the methodology used to approach the students' meaning making of the image of science as portrayed in the test were collaborative situations in which students work in small groups with units of PISA assignments, enabling a study of student-assignment encounters in action. The data we worked with consists of video-recordings from 71 Swedish 15-year-old students working with three released units from the PISA science test. According to our analysis, the "real-life situations" described in the test emerge as problematic in the students' meaning-making. This is demonstrated for instance by the students' positioning themselves as being different from and opposed to the fictional pictured students who appear in the backstories of the test. This article provides examples of how the scientific and academic language used by the fictional students in the assignments mediates distance and resistance among the students. The fictional students' use of strict scientific language and methods in day-to-day life situations leads them to be perceived as "little scientists" and as elite stereotypes of the scientific culture. We conclude that, by using assignments of this type, measurements of

  20. Variable Neighborhood Search for the University Lecturer-Student Assignment Problem

    CERN Document Server

    Geiger, Martin Josef

    2008-01-01

    The paper presents a study of local search heuristics in general and variable neighborhood search in particular for the resolution of an assignment problem studied in the practical work of universities. Here, students have to be assigned to scientific topics which are proposed and supported by members of staff. The problem involves the optimization under given preferences of students which may be expressed when applying for certain topics. It is possible to observe that variable neighborhood search leads to superior results for the tested problem instances. One instance is taken from an actual case, while others have been generated based on the real world data to support the analysis with a deeper analysis. An extension of the problem has been formulated by integrating a second objective function that simultaneously balances the workload of the members of staff while maximizing utility of the students. The algorithmic approach has been prototypically implemented in a computer system. One important aspect in t...

    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.

    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

    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

    Research into science identity, stereotype threat, and possible selves suggests a lack of diverse representations of scientists could impede traditionally underserved students from persisting and succeeding in science. We evaluated a series of metacognitive homework assignments ("Scientist Spotlights") that featured counterstereotypical examples of scientists in an introductory biology class at a diverse community college. Scientist Spotlights additionally served as tools for content coverage, as scientists were selected to match topics covered each week. We analyzed beginning- and end-of-course essays completed by students during each of five courses with Scientist Spotlights and two courses with equivalent homework assignments that lacked connections to the stories of diverse scientists. Students completing Scientist Spotlights shifted toward counterstereotypical descriptions of scientists and conveyed an enhanced ability to personally relate to scientists following the intervention. Longitudinal data suggested these shifts were maintained 6 months after the completion of the course. Analyses further uncovered correlations between these shifts, interest in science, and course grades. As Scientist Spotlights require very little class time and complement existing curricula, they represent a promising tool for enhancing science identity, shifting stereotypes, and connecting content to issues of equity and diversity in a broad range of STEM classrooms.

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

    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.

    The success of Advanced Traveler Information 5ystems (ATIS) and Advanced Traffic Management Systems (ATMS) depends on the availability and dissemination of timely and accurate estimates of current and emerging traffic network conditions. Real-time Dynamic Traffic Assignment (DTA) systems are being developed to provide the required timely information. The DTA systems will provide faithful and coherent real-time, pre-trip, and en-route guidance/information which includes routing, mode, and departure time suggestions for use by travelers, ATIS, and ATMS. To ensure the credibility and deployment potential of such DTA systems, an evaluation system supporting all phases of DTA system development has been designed and presented in this paper. This evaluation system is called the DTA System Laboratory (DSL). A major component of the DSL is a ground- truth simulator, the DTA Evaluation System (DES). The DES is envisioned to be a virtual representation of a transportation system in which ATMS and ATIS technologies are deployed. It simulates the driving and decision-making behavior of travelers in response to ATIS and ATMS guidance, information, and control. This paper presents the major evaluation requirements for a DTA Systems, a modular modeling framework for the DES, and a distributed DES design. The modeling framework for the DES is modular, meets the requirements, can be assembled using both legacy and independently developed modules, and can be implemented as a either a single process or a distributed system. The distributed design is extendible, provides for the optimization of distributed performance, and object-oriented design within each distributed component. A status report on the development of the DES and other research applications is also provided.

    2007-12-01

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

    The Lanyu is a miniature pig breed indigenous to Lanyu Island, Taiwan. It is distantly related to Asian and European pig breeds. It has been inbred to generate two breeds and crossed with Landrace and Duroc to produce two hybrids for laboratory use. Selecting sets of informative genetic markers to track the genetic qualities of laboratory animals and stud stock is an important function of genetic databases. For more than two decades, Lanyu derived breeds of common ancestry and crossbreeds have been used to examine the effectiveness of genetic marker selection and optimal approaches for individual assignment. In this paper, these pigs and the following breeds: Berkshire, Duroc, Landrace and Yorkshire, Meishan and Taoyuan, TLRI Black Pig No. 1, and Kaohsiung Animal Propagation Station Black pig are studied to build a genetic reference database. Nineteen microsatellite markers (loci) provide information on genetic variation and differentiation among studied breeds. High differentiation index (FST) and Cavalli-Sforza chord distances give genetic differentiation among breeds, including Lanyu's inbred populations. Inbreeding values (FIS) show that Lanyu and its derived inbred breeds have significant loss of heterozygosity. Individual assignment testing of 352 animals was done with different numbers of microsatellite markers in this study. The testing assigned 99% of the animals successfully into their correct reference populations based on 9 to 14 markers ranking D-scores, allelic number, expected heterozygosity (HE) or FST, respectively. All miss-assigned individuals came from close lineage Lanyu breeds. To improve individual assignment among close lineage breeds, microsatellite markers selected from Lanyu populations with high polymorphic, heterozygosity, FST and D-scores were used. Only 6 to 8 markers ranking HE, FST or allelic number were required to obtain 99% assignment accuracy. This result suggests empirical examination of assignment-error rates is required if

    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.

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

    Science.gov (United States)

    Pearson, Meghan Jeanne

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

    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.

    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.

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.

    Werth, Arman Karl

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

    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.

    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

    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

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

    Science.gov (United States)

    Bitner, Betty L.

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

    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.

  6. 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

    Spiegelberg, Bryan D

    2014-01-01

    Encouraging undergraduate students to access, read, and analyze current primary literature can positively impact learning, especially in advanced courses. The incorporation of literature into coursework typically involves reading and responding to full research reports. Such exercises have clear value as students make connections between experiments and are able to probe and critique scientific logic. The exclusive use of full papers, though, may reinforce certain students' tendencies to rely on textual clues rather than a critical analysis of the actual data presented. I propose that structured activities requiring students to focus on individual parts of research papers, even on a single figure, are beneficial in a literature-centered advanced undergraduate course, because they promote the deep reading that is critical to scientific discourse. In addition, I describe how one such focused assignment boosted learning and was well received by students in a second-semester biochemistry course.

    It is the position of the National Association of School Nurses (NASN) that schools should employ professionally prepared Registered Nurses, to conduct and supervise school health programs which address the variety of health problems experienced by school children. NASN recommends a formula-based approach with minimum ratios of nurses-to-students depending on the needs of the student populations as follows: 1:750 for students in the general population, 1:225 in the student populations requiring daily professional school nursing services or interventions, 1:125 in student populations with complex health care needs, and 1:1 may be necessary for individual students who require daily and continuous professional nursing services. Other factors that should be considered in the formula-based approach are number of students on free or reduced lunch, number of students with a medical home, and average number of emergency services per year.

    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). A total of 1102 (43.1%) answered student questionnaire

    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. Adicionalmente, se establecen un conjunto de restricciones relacionadas con el enfoque en los ritmos cognitivos, determinando las horas de la jornada en las que es más conveniente la ubicación de ciertas materias de acuerdo al área del conocimiento al que pertenecen. El algoritmo genético evoluciona mediante un proceso de mutación y selección, a través del cual se construye una solución completa a partir de la búsqueda de las mejores soluciones por grupo. Se presentan los resultados de las pruebas realizadas para la asignación de una institución con 16 grupos. La calidad de las soluciones obtenidas de acuerdo al enfoque establecido es validada

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

    Science.gov (United States)

    Fisanick, Laura M.

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

    2016-09-01

    The importance of language in mathematics learning has been widely acknowledged. However, little is known about how to make this insight productive in the design and enactment of language-oriented mathematics education. In a design-based research project, we explored how language-oriented mathematics education can be designed and enacted. We drew on genre pedagogy to promote student proficiency in the language required for interpreting line graphs. In the intervention, the teacher used scaffolding strategies to focus students' attention on the structure and linguistic features of the language involved in this particular domain. The research question addressed in this paper is how student proficiency in this language may be promoted. The study comprised nine lessons involving 22 students in grades 5 and 6 (aged 10-12); of these students, 19 had a migrant background. In light of the research aim, we first describe the rationale behind our design. Next, we illustrate how the design was enacted by means of a case study focusing on one student in the classroom practice of developing proficiency in the language required for interpreting line graphs. On the basis of pre- and posttest scores, we conclude that overall their proficiency has increased. Together, the results indicate that and how genre pedagogy may be used to help students become more proficient in the language required in a mathematical domain.

    2011-04-01

    The influence of Graduate Record Examination (GRE) requirements on undergraduate students' perceptions of a fictitious clinical psychology graduate program was examined. The more rigorous a program's GRE requirement, the more highly students were expected to rate the program on quality, reputation, challenge of curriculum, attractiveness, and their willingness to apply. 140 undergraduate participants read and rated one of three possible program descriptions that differed only with regard to the stated GRE requirements. Although the effects were small, participants rated the program requiring a minimum combined GRE score of 1,200 (verbal and quantitative) as higher in quality and as having a more challenging curriculum compared to the program that required the GRE but with no minimum score. Although preliminary, these findings are consistent with previous research demonstrating that graduate school applicants use GRE requirements in their evaluation of graduate programs.

    Rew, Lynn

    2012-12-01

    Both undergraduate and graduate nursing students are expected to write numerous papers in their educational programs; however, most of these papers are never published. Many students and faculty lack the skills needed to convert a course assignment paper to a publishable manuscript. The purpose of this article is to describe 10 steps that can transform a course assignment paper into a publishable manuscript. These steps include outlining, clarifying the topic, clearly stating the purpose, identifying an appropriate audience, revising with faculty's feedback, querying journal editors, revising to conform to journal's author guidelines, requesting and responding to peer feedback, and finally editing and proofreading prior to submitting the manuscript. Faculty members are encouraged to make writing assignments that students can then convert to publishable manuscripts. Such publications form an essential cornerstone of professional holistic nursing.

    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).

    Full Text Available Despite integration of advanced functions that enable Femto Access Points (FAPs to be deployed in a plug-and-play manner, the femtocell concept still cause several opened issues to be resolved. One of them represents an assignment of Physical Cell Identifiers (PCIs to FAPs. This paper analyses a random based assignment algorithm in LTE systems operating in diverse femtocell scenarios. The performance of the algorithm is evaluated by comparing the number of confusions for various femtocell densities, PCI ranges and knowledge of vicinity. Simulation results show that better knowledge of vicinity can significantly reduce the number of confusions events.

    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. Conclusion: Practical training plays an important role in adaptation of young X-ray technicians to the conditions of medical work, improving their skills and habits, and to the development of specific practical skills for being able to respond to emergency conditions and to solve complicated practical situations. The mentor is the supervisor and the controller of interns who helps this happen through his own example, qualities and attitudes towards

    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.

    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.

  5. 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

    Directory of Open Access Journals (Sweden)

    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.

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

    Directory of Open Access Journals (Sweden)

    Bonnie L. Fong

    2015-06-01

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

    Faulk, Clinton E; Mali, Jimmy; Mendoza, Paola Maria; Musick, David; Sembrano, Roderick

    2012-05-01

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

    Comments on students’ assignments are important for English course. The loopholes in teachers’ working schemes-com-ments of their students’ written assignments are the clues around which the paper spreads. In the process of teaching, some English teach-ers pay so much attention to the contents taught in class but ignore the comments on students’ written assignments. Consequently, it is not applicable for students to correct their mistakes in time and they probably make the same mistakes repeatedly.

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

    Directory of Open Access Journals (Sweden)

    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.

    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.

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

    Energy Technology Data Exchange (ETDEWEB)

    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.

  4. Assignment of fields from particles to mesh

    CERN Document Server

    Duque, Daniel

    2016-01-01

    In Computational Fluid Dynamics there have been many attempts to combine the power of a fixed mesh on which to carry out spatial calculations with that of a set of particles that moves following the velocity field. These ideas indeed go back to Particle-in-Cell methods, proposed about 60 years ago. Of course, some procedure is needed to transfer field information between particles and mesh. There are many possible choices for this "assignment", or "projection". Several requirements may guide this choice. Two well-known ones are conservativity and stability, which apply to volume integrals of the fields. An additional one is here considered: preservation of information. This means that mesh interpolation, followed by mesh assignment, should leave the field values invariant. The resulting methods are termed "mass" assignments due to their strong similarities with the Finite Element Method. We test several procedures, including the well-known FLIP, on three scenarios: simple 1D convection, 2D convection of Zales...

  4. Students' Self-Assessment in Chemistry Examinations Requiring Higher- and Lower-Order Cognitive Skills

    Zoller*, Uri; Fastow, Michal; Lubezky, Aviva; Tsaparlis, Georgios

    1999-01-01

    The development of students' higher-order cognitive skills (HOCS) in the context of both chemistry and the complex interrelationships of science, technology, environment, and society is widely accepted as one of the most important goals of chemical education. Consequently, the translation of this goal into teaching, assessment, and learning strategies is a central issue in chemistry teaching. Students' self-assessment in chemistry examinations is a HOCS-promoting strategy. We evaluated the differences between students' self-assessment and their professors' assessment on midterm exams in introductory college courses in Israel and Greece, together with the students' appraisal of their capability for self- and peer-assessment. We found that (i) there were small (not significant) and large (significant) differences between students' self-grading and their professors' grading on LOCS and HOCS exam questions, respectively; (ii) students' estimates of their grades were higher than those of their professors, particularly for HOCS questions; and (iii) students believed that they were capable of self- and peer-assessment and were confident in making these assessments. Our results suggest that (i) students' self-assessment of LOCS-type exams can be successfully implemented immediately, whereas (ii) implementation of self-assessment for HOCS-type exam questions should be gradual, following appropriate preparation to close the gap between the future HOCS and contemporary dominant LOCS orientations in chemistry teaching and learning.

    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

    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.

    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

    1991-01-01

    This article discusses the application of a zero-one approach to the development of a total program schedule that assigns students to all required clinical courses in an academic nursing program. The approach is based on an operations research technique, zero-one programming. Unlike zero-one programming, the objective function in this formulation is arbitrary; any solution that meets the constraints of the system is acceptable. Also described in this article are the constraints that limit flexibility of student assignments (i.e., available clinical sites and units, instructors, day or evening, maximum class sizes, order of courses), a solution to the scheduling problem at Saint Joseph's (which involves 1,067 equations), and suggestions for the general utility of a zero-one approach for similar administrative problems.

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

    Directory of Open Access Journals (Sweden)

    2010-04-01

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

    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

    Objective Colleges are at risk for communicable disease outbreaks because of the high degree of person-to-person interactions and relatively crowded dormitory settings. This report describes the U.S. college student health screening requirements among U.S. resident and international students for tuberculosis (TB) and vaccine-preventable diseases (VPD) as it relates to the American College Health Association (ACHA) Guidelines. Methods/Participants In April 2012, U.S. college health administrators (N=2858) were sent online surveys to assess their respective school’s TB screening and immunization requirements. Results Surveys were completed by 308 (11%) schools. Most schools were aware of the ACHA immunization (78%) and TB screening (76%) guidelines. Schools reported having policies related to immunization screening (80.4%), immunization compliance (93%), TB screening (55%), and TB compliance (87%). Conclusion Most colleges were following ACHA guidelines. However, there are opportunities for improvement to fully utilize the recommendations and prevent outbreaks of communicable diseases among students in colleges. PMID:26730492

    The purpose of this pilot study was to compare embedded audio feedback (EAF), which faculty provided using the iPad(®) application iAnnotate(®) PDF to insert audio comments and written feedback (WF), inserted electronically on student papers in a series of writing assignments. Goals included determining whether EAF provides more useful guidance to students than WF and whether EAF promotes connectedness among students and faculty. An additional goal was to ascertain the efficiency and acceptance of EAF as a grading tool by nursing faculty. The pilot study was a quasi-experimental, cross-over, posttest-only design. The project was completed in an Informatics in Health Care course. Faculty alternated the two feedback methods on four papers written by each student. Results of surveys and focus groups revealed that students and faculty had mixed feelings about this technology. Student preferences were equally divided between EAF and WF, with 35% for each, and 28% were undecided.

    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.

    Full Text Available Introduction: Competency-based education has been recommended in training and education of public health to reduce the gap between traditional teaching and the competencies required in practice. Epidemiology as a fundamental of public health science has come to attention. The aim of this study was to introduce a complementary core competency program for Master of Science (MSc in epidemiology students in Iran. Methods: A workgroup in the department of statistics and epidemiology of Tabriz University of Medical Sciences including five epidemiologists and three biostatisticians prepared an outline of complementary core competencies for epidemiology MSc students. In the first step several discussion rounds were done to review the current curriculum, then the workgroup sought students’ opinions to find out about their needs. In addition, a review of the current literature around the topic was done. In the final step the program components were developed by the workgroup and initially implemented. Results: A complementary program consists of eight domains: general knowledge, problem finding, data analysis and interpretation, communications, management, consultation, leadership skills and professionalism. This program focused on basic competencies and those competencies outside the major field for a graduate of epidemiology to enhance their knowledge, attitude and skills. The program was scheduled to run in the third semester and approximate time for completion was three months. Conclusion: The development and initial implementation of the complementary core competency program was successful and the authors will attempt to extend the program and evaluate the implementation phase.

    Laboratory classes are regarded as an important learning activity, but they also have shortcomings: laboratory classes are often an inefficient learning activity for students and often do not sufficiently support students in developing research specific cognitive skills. It is hypothesized that some of such skills can be achieved more effectively with digital assignments than with laboratory classes. Therefore, three digital assignments have been designed, developed and evaluated. The assignments have three goals: (1) providing a situation in which students can practice research specific cognitive skills and (2) offering a research method which students can also use in a real laboratory situation and (3) providing the possibility to come across a number of common pitfalls. The assignments are described in detail. Results of a first evaluation of the use of the assignments indicate that the students consider the assignments challenging and valuable. The examination results demonstrate that students are quite capable of making a research design. Although students indicate to have learned a useful research method, students do not apply the method in the laboratory classes.

  19. ZAP: a distributed channel assignment algorithm for cognitive radio networks

    Directory of Open Access Journals (Sweden)

    Munaretto Anelise

    2011-01-01

    Full Text Available Abstract We propose ZAP, an algorithm for the distributed channel assignment in cognitive radio (CR networks. CRs are capable of identifying underutilized licensed bands of the spectrum, allowing their reuse by secondary users without interfering with primary users. In this context, efficient channel assignment is challenging as ideally it must be simple, incur acceptable communication overhead, provide timely response, and be adaptive to accommodate frequent changes in the network. Another challenge is the optimization of network capacity through interference minimization. In contrast to related work, ZAP addresses these challenges with a fully distributed approach based only on local (neighborhood knowledge, while significantly reducing computational costs and the number of messages required for channel assignment. Simulations confirm the efficiency of ZAP in terms of (i the performance tradeoff between different metrics and (ii the fast achievement of a suitable assignment solution regardless of network size and density.

  3. Assigning functional meaning to digital circuits

    Eckmann, S.T.; Chisholm, G.H. [Argonne National Lab., IL (United States). Decision and Information Sciences Div.

    1997-07-01

    During computer-aided design, the problem of how to determine the logical function of a digital circuit arises in many contexts. For example, assigning functional meaning to a circuit is a fundamental operation in both reverse engineering and implementation validation. This report describes such a determination by discussing how a higher-level functional representation is constructed from a detailed circuit description (i.e., a gate-level netlist, which is a list of logic gates and their interconnections). The approach used involves transforming parts of the netlist into a functional representation and then manipulating this representation. Two types of functional representations are described: (1) a mathematical representation based on the logical operators ``exor`` and ``and`` and (2) a directed acyclic graph representation based on binary decision trees. Each representation provides a canonical form of the logical function being implemented (i.e., a form that is independent of implementation details). Such forms, however, have a well-known problem associated with the ordering of inputs: for each order, a unique form exists. A solution to this problem is given for both representations. Experimental results that demonstrate the use of these representations in the process of assigning functional meaning to a circuit are provided. The report also identifies and discusses issues critical to the performance required of this fundamental operation.

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.

    2010-12-01

    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:

  8. More General Optimal Offset Assignment

    Directory of Open Access Journals (Sweden)

    Sven Mallach

    2015-06-01

    Full Text Available This manuscript presents exact approaches to the general offset assignment problem arising in the address code generation phase of compilers for application-specific processors. First, integer programming models for architecture-dependent and theoretically motivated special cases of the problem are established. Then, these models are extended to provide the first widely applicable formulations for the most general problem setting, supporting processors with several address registers and complex addressing capabilities. Existing heuristics are similarly extended and practical applicability of the proposed methods is demonstrated by experimental evaluation using an established and large benchmark set. The experiments allow us to study the impact of exploiting more complex memory addressing capabilities on the address computation costs of real-world programs. We also show how to integrate operand reordering techniques for commutative instructions into existing solution approaches.

    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

  16. Integrated assignment and path planning

    Murphey, Robert A.

    2005-11-01

    A surge of interest in unmanned systems has exposed many new and challenging research problems across many fields of engineering and mathematics. These systems have the potential of transforming our society by replacing dangerous and dirty jobs with networks of moving machines. This vision is fundamentally separate from the modern view of robotics in that sophisticated behavior is realizable not by increasing individual vehicle complexity, but instead through collaborative teaming that relies on collective perception, abstraction, decision making, and manipulation. Obvious examples where collective robotics will make an impact include planetary exploration, space structure assembly, remote and undersea mining, hazardous material handling and clean-up, and search and rescue. Nonetheless, the phenomenon driving this technology trend is the increasing reliance of the US military on unmanned vehicles, specifically, aircraft. Only a few years ago, following years of resistance to the use of unmanned systems, the military and civilian leadership in the United States reversed itself and have recently demonstrated surprisingly broad acceptance of increasingly pervasive use of unmanned platforms in defense surveillance, and even attack. However, as rapidly as unmanned systems have gained acceptance, the defense research community has discovered the technical pitfalls that lie ahead, especially for operating collective groups of unmanned platforms. A great deal of talent and energy has been devoted to solving these technical problems, which tend to fall into two categories: resource allocation of vehicles to objectives, and path planning of vehicle trajectories. An extensive amount of research has been conducted in each direction, yet, surprisingly, very little work has considered the integrated problem of assignment and path planning. This dissertation presents a framework for studying integrated assignment and path planning and then moves on to suggest an exact

    This article describes a teaching strategy used in an undergraduate gerontological nursing clinical course to familiarize students with evidence-based practice. Students are required to read and summarize an assigned evidence-based practice guideline published by The University of Iowa Gerontological Nursing Interventions Research Center. They then develop a "tip sheet," based on the assigned guideline, to disseminate to health care staff at their practicum sites, which is either a long-term care facility or a hospital-based skilled nursing facility. Nursing students' reactions to the assignment and nursing staff's responses to the tip sheets are discussed.

    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.

  3. Solving multiconstraint assignment problems using learning automata.

    Science.gov (United States)

    Horn, Geir; Oommen, B John

    2010-02-01

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

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

    Science.gov (United States)

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

    2010-05-01

    The US National Science Education Standards (2000) state that science should be taught through inquiry. The five essential features of classroom inquiry are that the leaner (i) engages in scientifically oriented questions, (ii) gives priority to evidence in responding to questions, (iii) formulates explanations from evidence, (iv) connects explanations to scientific knowledge, and (v) communicates and justifies explanations. One difficulty in achieving this vision at the university level lies in the common perception that inquiry be fully open and unstructured, and that its implementation will be impractical due to time and material constraints. In an NSF-funded project, "CUES: Connecting Undergraduates to the Enterprise of Science," faculty developed new inquiry-based laboratory curriculum materials using a "mini-journal" approach, which is designed as an alternative to the cookbook laboratory and represents the way that scientists do science. Here we adapt this approach to a homework assignment in an upper-level Planetary Science class, and show that inquiry is achievable in this setting. Traditional homeworks in this class consisted of problem sets requiring algebraic manipulation, computation, and in most cases an appraisal of the result Longer questions are broken down into chunks worth 1 to 4 points. In contrast, the mini-journal is a short article that is modeled in the way that scientists do and report science. It includes a title, abstract, introduction (with clear statement of the problem to be tackled), a description of the methods, results (presented as both tables and graphs), a discussion (with suggestions for future work) and a list of cited work. Students devise their research questions and hypothesis from the paper based on a logical next step in the investigation. Guiding questions in the discussion can assist the students ("it would be interesting to evaluate the effect of ..."). Students submit their own minijournal, using the same journal

  1. Airport Gate Assignment: New Model and Implementation

    CERN Document Server

    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.

  3. Efficient Credit Assignment through Evaluation Function Decomposition

    Science.gov (United States)

    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.

  4. Scientist Spotlight Homework Assignments Shift Students’ Stereotypes of Scientists and Enhance Science Identity in a Diverse Introductory Science Class

    Science.gov (United States)

    Schinske, Jeffrey N.; Perkins, Heather; Snyder, Amanda; Wyer, Mary

    2016-01-01

    Research into science identity, stereotype threat, and possible selves suggests a lack of diverse representations of scientists could impede traditionally underserved students from persisting and succeeding in science. We evaluated a series of metacognitive homework assignments (“Scientist Spotlights”) that featured counterstereotypical examples of scientists in an introductory biology class at a diverse community college. Scientist Spotlights additionally served as tools for content coverage, as scientists were selected to match topics covered each week. We analyzed beginning- and end-of-course essays completed by students during each of five courses with Scientist Spotlights and two courses with equivalent homework assignments that lacked connections to the stories of diverse scientists. Students completing Scientist Spotlights shifted toward counterstereotypical descriptions of scientists and conveyed an enhanced ability to personally relate to scientists following the intervention. Longitudinal data suggested these shifts were maintained 6 months after the completion of the course. Analyses further uncovered correlations between these shifts, interest in science, and course grades. As Scientist Spotlights require very little class time and complement existing curricula, they represent a promising tool for enhancing science identity, shifting stereotypes, and connecting content to issues of equity and diversity in a broad range of STEM classrooms.

    It can be seen through a course assignment that course papers have many defects.For example,students have no strictly academic standards,a narrow academic vision,logic thinking disorder,academic thesis format confusion and so on.It shows that college students' academic writing ability are on a low level these years.This caused the attention of researchers,but they mostly ignored the vital role of course teacher and daily teaching.The course teachers should be teaching in the daily course combined with writing course papers to enhance the academic writing skills,to cultivate more excellent students.In the process,the course teachers should change the students ideas not to emphasis on writing,but broaden the academic horizons,strengthen the logic of practice,and urge students to cultivate detailed rigorous style of study.The teachers will also take a solid step forward in the road of becoming educators.%从一次课程作业可以看出,大学生存在着不能严守学术规范、学术视野狭窄、逻辑思维紊乱、论文格式混乱等问题,反映出目前大学生学术写作能力偏低。这引起了研究者的关注,但大多忽视了任课教师和日常教学的重要作用。任课教师应该在日常教学中结合课程论文的写作,转变学生不重视论文写作的思想,开阔其学术视野,加强逻辑方法训练,督促学生养成细致严谨的学风,以提高学术写作能力。

    In the last decade, the prediction of protein secondary structure has been optimized using essentially one and the same assignment scheme known as DSSP. We present here a different scheme, which is more predictable. This scheme predicts directly the hydrogen bonds, which stabilize the secondary...... structures. Single sequence prediction of the new three category assignment gives an overall prediction improvement of 3.1% and 5.1%, compared to the DSSP assignment and schemes where the helix category consists of a-helix and 3(10)-helix, respectively. These results were achieved using a standard feed-forward...

    Let v be an assignment game. For a given reference payoff vector (x; y), and a coalition S, bargaining within the coalition can be represented by either the reduced game or the derived game. It is known that the reduced game need not be an assignment game (in fact, it need not be super additive) while the derived game is another assignment game, with modified reservation prices. We prove that, when the reference vector is in the core of the game, the derived game is the super additive cover o...

    2005-01-01

    Crosstalk noise is one of the emerging issues in deep sub-micrometer technology which causes many undesired effects on the circuit performance. In this paper, a Crosstalk-Aware Routing Resource Assignment (CARRA) algorithm is proposed, which integrates the routing layers and tracks to address the crosstalk noise issue during the track/layer assignment stage. The CARRA problem is formulated as a weighted bipartite matching problem and solved using the linear assignment algorithm. The crosstalk risks between nets are represented by an undirected graph and the maximum number of the concurrent crosstalk risking nets is computed as the max clique of the graph. Then the nets in each max clique are assigned to disadjacent tracks. Thus the crosstalk noise can be avoided based on the clique concept. The algorithm is tested on IBM benchmarks and the experimental results show that it can improve the final routing layout a lot with little loss of the completion rate.

    Writing assignments, including note taking and written recall, should enhance retention of knowledge, whereas analytical writing tasks with metacognitive aspects should enhance higher-order thinking. In this study, we assessed how certain writing-intensive "interventions," such as written exam corrections and peer-reviewed writing assignments using Calibrated Peer Review and including a metacognitive component, improve student learning. We designed and tested the possible benefits of these approaches using control and experimental variables across and between our three-section introductory biology course. Based on assessment, students who corrected exam questions showed significant improvement on postexam assessment compared with their nonparticipating peers. Differences were also observed between students participating in written and discussion-based exercises. Students with low ACT scores benefited equally from written and discussion-based exam corrections, whereas students with midrange to high ACT scores benefited more from written than discussion-based exam corrections. Students scored higher on topics learned via peer-reviewed writing assignments relative to learning in an active classroom discussion or traditional lecture. However, students with low ACT scores (17-23) did not show the same benefit from peer-reviewed written essays as the other students. These changes offer significant student learning benefits with minimal additional effort by the instructors.

  3. Competitive Traffic Assignment in Road Networks

    Directory of Open Access Journals (Sweden)

    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.

    2015-12-01

    Millennial students are often characterized as technology focused multitaskers, yet young nursing students are expected to focus on and thoughtfully engage with the person at the center of their caring efforts. Developing gratitude practices requires quiet contemplation and focus. Cultivating an attitude of gratitude in millennial nursing students may be one avenue to address concerns surrounding the provision of relationship based person-centered care by young nurses. In other disciplines, gratitude work has been studied extensively and is associated with several positive outcomes. Assignments included in most nursing programs can easily be modified to include a gratitude focus. Examples of gratitude assignments and the student reflection of these assignments are included here as a call for nurse educators to further study this concept. PMID:26362068

    Full Text Available Students’ error analysis is very important for helping EFL teachers to develop their teaching materials, assessments and methods. However, it takes much time and effort from the teachers to do such an error analysis towards their students’ language. This study seeks to identify the common errors made by 1 class of 28 freshmen students studying English in their first semester in an IT university. The data is collected from their writing assignments for eight consecutive weeks. The errors found were classified into 24 types and the top ten most common errors committed by the students were article, preposition, spelling, word choice, subject-verb agreement, auxiliary verb, plural form, verb form, capital letter, and meaningless sentences. The findings about the students’ frequency of committing errors were, then, contrasted to their midterm test result and in order to find out the reasons behind the error recurrence; the students were given some questions to answer in a questionnaire format. Most of the students admitted that careless was the major reason for their errors and lack understanding came next. This study suggests EFL teachers to devote their time to continuously check the students’ language by giving corrections so that the students can learn from their errors and stop committing the same errors.

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

    Science.gov (United States)

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

    2011-12-01

    As part of an NSF-funded project, "CUES: Connecting Undergraduates to the Enterprise of Science," new inquiry-based homework materials were developed for two upper-level classes at the University of Missouri: Geochemistry (required for Geology majors, fulfills the computing requirement by having 50% of the grade come from five spreadsheet-based homework assignments), and Solar System Science (open to seniors and graduate students, co-taught and cross-listed between Geology and Physics & Astronomy). Inquiry involves activities where the learner engages in scientifically oriented questions, gives priority to evidence in responding to questions, formulates explanations from evidence, connects explanations to scientific knowledge, and communicates and justifies explanations. We engage students in inquiry-based learning by presenting homework exercises as "mini-journal" articles that follow the format of a scientific journal article, including a title, authors, abstract, introduction, methods, results, discussion and citations to peer-reviewed literature. The mini-journal provides a scaffold and serves as a springboard for students to develop and carry out their own follow-up investigation. They then present their findings in the form of their own mini-journal. Mini-journals replace traditional homework problem sets with a format that more directly reflects and encourages scientific practice. Students are engaged in inquiry-based homework which encompass doing, thinking, and communicating, while the mini-journal allows the instructor to contain lines of inquiry within the limits posed by available resources. In the examples we present, research is conducted via spreadsheet modeling, where the students develop their own spreadsheets. Example assignments from Geochemistry include "Trace Element Partitioning During Mantle Melting and MORB Crystallization" and "Isotopic Investigations of Crustal Evolution in the Midcontinent US".

  13. Recognizing the "Transformational" in Preservice Digital Literacy Assignments

    Science.gov (United States)

    Robertson, Lorayne; Hughes, Janette

    The authors review and evaluate a Teaching Methods course in Language and Literacy, one which focuses on multiple literacies, including digital literacy and critical literacy. The course is offered in a laptop-based university program. In this article, the authors outline the context of the multiple literacies course, its resources and assignments as well as their instructional goals. Their qualitative data sources include student-created digital artifacts such as digital literacy stories and digital book talks. The researchers draw from cross-program data based on hundreds of student reflections and one-on-one interviews. The authors conclude that there are indications from their data analysis that suggest that digital literacy supports the development of "transformative elements" that can extend beyond the teacher training program.

  14. Flexible taxonomic assignment of ambiguous sequencing reads

    Directory of Open Access Journals (Sweden)

    Jansson Jesper

    2011-01-01

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

  16. Student Blogging about Physics

    2010-09-01

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

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

    Directory of Open Access Journals (Sweden)

    de Brevern Alexandre G

    2005-09-01

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

  18. Unifying Temporal and Structural Credit Assignment Problems

    Science.gov (United States)

    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.

    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.

    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.

  2. 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 ...

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 backgroun...

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

    Directory of Open Access Journals (Sweden)

    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

    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.

    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.

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

    Science.gov (United States)

    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.

    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

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

    Directory of Open Access Journals (Sweden)

    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.

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

    Directory of Open Access Journals (Sweden)

    Kleanthis C. THRAMBOULIDIS

    2003-04-01

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

    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.

    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 place ment 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.

  13. 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

    Interprofessional education (IPE) is increasingly called upon to improve health care systems and patient safety. Our institution is engaged in a campus-wide IPE initiative. As a component of this initiative, a required online interprofessional patient-safety-focused course for a large group (300) of first-year medical, dental, and nursing students was developed and implemented. We describe our efforts with developing the course, including the use of constructivist and adult learning theories and IPE competencies to structure students' learning in a meaningful fashion. The course was conducted online to address obstacles of academic calendars and provide flexibility for faculty participation. Students worked in small groups online with a faculty facilitator. Thematic modules were created with associated objectives, online learning materials, and assignments. Students posted completed assignments online and responded to group members' assignments for purposes of group discussion. Students worked in interprofessional groups on a project requiring them to complete a root cause analysis and develop recommendations based on a fictional sentinel event case. Through project work, students applied concepts learned in the course related to improving patient safety and demonstrated interprofessional collaboration skills. Projects were presented during a final in-class session. Student course evaluation results suggest that learning objectives and content goals were achieved. Faculty course evaluation results indicate that the course was perceived to be a worthwhile learning experience for students. We offer the following recommendations to others interested in developing an in-depth interprofessional learning experience for a large group of learners: 1) consider a hybrid format (inclusion of some face-to-face sessions), 2) address IPE and broader curricular needs, 3) create interactive opportunities for shared learning and working together, 4) provide support to faculty

    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

    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.

    2013-01-01

    Veterinary schools are increasingly developing students' communication skills, with an emphasis placed on practice conveying medical and scientific knowledge to different audiences. We describe how patient-centered written communication has been integrated into the training of veterinary students using toxicology-related preventive materials. Third-year veterinary students were given an assignment to prepare a client-focused brochure related to veterinary toxicology. Since 2010, 148 students have completed this assignment, with an average score of 93.4%. Use of a grading rubric was instituted in 2011 and resulted in a more rigorous assessment of the brochures by the course instructors. In this study, we evaluated a sample (n=6) selected from 10 brochures volunteered for further public and expert assessment. Each brochure was measured for readability and assessed with a rubric for perceived usefulness and acceptability by 12 veterinary toxicologists and 10 or 11 adult members of the public attending a college of veterinary medicine open house. Veterinary toxicologist review anticipated that the brochures would be useful for most clients, and the public reviewers confirmed this assessment. Evaluation of the brochures using set marking criteria and readability indexes showed that students had successfully targeted the chosen audiences. Feedback showed that the general public rated the sample brochures highly in terms of quality, usefulness, and interest. Completion of this study has resulted in revision of the grading rubric, an increased use of brochure examples, and additional instruction in readability assessment and brochure development, thereby improving the assignment as a learning exercise.

    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.

  1. 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

    Full Text Available I teach an upper-level writing course, Genes, Race, Gender, and Society, designed for Life Science majors, in which I utilize a case study to expose students to ethical ways of thinking.  Students first work through the topical case study and then are challenged to rethink their responses through the lenses of ethics, taking into account different ethical frameworks.  Students then develop their own case study, integrating ethical components.  I want to expose my students to this way of thinking because I see technology being driven by the Jurassic Park phenomenon, "Your scientists were so preoccupied with whether or not they could, they didn't stop to think if they should." and want future physicians grounded in a sense of how their actions relate to the greater good.

    Randomized controlled trials (RCT) have gained ground as the dominant tool for studying policy interventions in many fields of applied economics. We analyse theoretically encouragement and resentful demoralization in RCTs and show that these might be rooted in the same behavioural trait - people......’s propensity to act reciprocally. When people are motivated by reciprocity, the choice of assignment procedure influences the RCTs’ findings. We show that even credible and explicit randomization procedures do not guarantee an unbiased prediction of the impact of policy interventions; however, they minimize...

    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.

    2012-01-01

    Full Text Available 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. This paper provides a comprehensive literature review of quantitative approaches in dock door assignment problems of cross docking planning. The contributions of this paper are to identify the gap of knowledge in operational levels mainly in dock door assignment and to point out the future research direction in cross docking.

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

    International Nuclear Information System (INIS)

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

  7. 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

  10. Improving load balance with flexibly assignable tasks

    Pinar, Ali; Hendrickson, Bruce

    2003-09-09

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

    Rickles, Jordan H

    2011-10-01

    Many inquiries regarding the causal effects of policies or programs are based on research designs where the treatment assignment process is unknown, and thus valid inferences depend on tenuous assumptions about the assignment mechanism. This article draws attention to the importance of understanding the assignment mechanism in policy and program evaluation studies, and illustrates how information collected through interviews can develop a richer understanding of the assignment mechanism. Focusing on the issue of student assignment to algebra in 8th grade, I show how a preliminary data collection effort aimed at understanding the assignment mechanism is particularly beneficial in multisite observational studies in education. The findings, based on ten interviews and administrative data from a large school district, draw attention to the often ignored heterogeneity in the assignment mechanism across schools. These findings likely extend beyond the current research project in question to related educational policy issues such as ability grouping, tracking, differential course taking, and curricular intensity, as well as other social programs in which the assignment mechanism can differ across sites.

    Science.gov (United States)

    McNeal, A P; Silverthorn, D U; Stratton, D B

    1998-12-01

    Many faculty want to involve students more actively in laboratories and in experimental design. However, just "turning them loose in the lab" is time-consuming and can be frustrating for both students and faculty. We describe three different ways of providing structures for labs that require students to design their own experiments but guide the choices. One approach emphasizes invertebrate preparations and classic techniques that students can learn fairly easily. Students must read relevant primary literature and learn each technique in one week, and then design and carry out their own experiments in the next week. Another approach provides a "design framework" for the experiments so that all students are using the same technique and the same statistical comparisons, whereas their experimental questions differ widely. The third approach involves assigning the questions or problems but challenging students to design good protocols to answer these questions. In each case, there is a mixture of structure and freedom that works for the level of the students, the resources available, and our particular aims.

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

    Science.gov (United States)

    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.

    2009-01-01

    The wavelength assignment with multiple multicast requests in fixed routing WDM network is studied. A new multicast dynamic wavelength assignment algorithm is presented based on matching degree. First, the wavelength matching degree between available wavelengths and multicast routing trees is introduced into the algorithm. Then, the wavelength assign-ment is translated into the maximum weight matching in bipartite graph, and this matching problem is solved by using an extended Kuhn-Munkres algorithm. The simulation results prove that the overall optimal wavelength assignment scheme is obtained in polynomial time. At the same time, the proposed algorithm can reduce the connecting blocking probability and improve the system resource utilization.

    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.

  7. Regulatory focus and the assignment of punishment

    Directory of Open Access Journals (Sweden)

    2007-06-01

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

    Metagenomics is providing an unprecedented access to the environmental microbial diversity. The amplicon-based metagenomics approach involves the PCR-targeted sequencing of a genetic locus fitting different features. Namely, it must be ubiquitous in the taxonomic range of interest, variable enough to discriminate between different species but flanked by highly conserved sequences, and of suitable size to be sequenced through next-generation platforms. The internal transcribed spacers 1 and 2 (ITS1 and ITS2) of the ribosomal DNA operon and one or more hyper-variable regions of 16S ribosomal RNA gene are typically used to identify fungal and bacterial species, respectively. In this context, reliable reference databases and taxonomies are crucial to assign amplicon sequence reads to the correct phylogenetic ranks. Several resources provide consistent phylogenetic classification of publicly available 16S ribosomal DNA sequences, whereas the state of ribosomal internal transcribed spacers reference databases is notably less advanced. In this review, we aim to give an overview of existing reference resources for both types of markers, highlighting strengths and possible shortcomings of their use for metagenomics purposes. Moreover, we present a new database, ITSoneDB, of well annotated and phylogenetically classified ITS1 sequences to be used as a reference collection in metagenomic studies of environmental fungal communities. ITSoneDB is available for download and browsing at http://itsonedb.ba.itb.cnr.it/.

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

    Science.gov (United States)

    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

    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).

  18. Implementation of an agile maintenance mechanic assignment methodology

    Science.gov (United States)

    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.

    Hite, M F

    2001-05-01

    A new case study method of assessment was developed to challenge advanced undergraduate biology majors interested in medical careers and allied health professions. This method is an alternative to traditional "unknown" identifications used in many microbiology laboratories. Students used various biochemical tests and selective media throughout the course to identify organisms cultured from their own bodies. 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. PMID:23653537

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

    Directory of Open Access Journals (Sweden)

    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.

  14. Multiobjective controller synthesis via eigenstructure assignment with state feedback

    Science.gov (United States)

    Li, Zhao; Lam, James

    2016-10-01

    A general parameter scheme for multiobjective controller synthesis via eigenstructure assignment with state feedback is proposed. The scheme provides total pole configurability, that is, pole assignment constraints, partial pole assignment constraints, generalised regional pole assignment constraints can be dealt with simultaneously without introducing essential conservatism. The scheme is derived from the pole assignment approach using Sylvester equations, and the parameter space is the Cartesian product of some subspaces characterising the free parameters. Under the scheme, the controller design problems are formulated as nonlinear optimisation problems with both objectives and constraints being differentiable and can be solved by derivative-based nonlinear programming technique. Numerical examples are given to illustrate the efficiency of the proposed method.

  15. 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.

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

    Science.gov (United States)

    Wetzel, L. R.

    2011-12-01

    A letter from the fictional Art for the Smart company addresses students in the Earth Materials course: "You might be wondering why an artist needs a geology consultant. I am creating a sculpture garden filled with mythical beings. I would like each student to recommend two unique minerals for one of these sculptures..." For this project students randomly select a mythical being, two mineral groups, and a mineral characteristic. For example, a student might be assigned the goddess Freya, a sulfate, a vanadate, and twinning. Students then choose a specific mineral from each group, describe their physical and chemical characteristics, and recommend how the minerals could be incorporated into the sculpture. Reports are presented in short oral presentations and two-page business letters with accompanying bibliography and illustrations. The letter format provides a concise way to communicate results to the Art for the Smart "client" while preparing students for their job-hunting days ahead. The oral presentations are structured as features for a news program. Talks are limited to three to five minutes and four slides: title page, mineral #1, mineral #2, and mythical being. The strict limits help students concentrate on scientific content and smooth delivery rather than flashy visual aids. The student audience and the professor evaluate each in-class presentation. This has become a popular assignment because it engages student imaginations to relate minerals to mythical beings and creatively design a sculpture. Each project is unique and therefore more interesting for both students and faculty to evaluate. The projects are nearly impossible to plagiarize from previous years or from internet sources. Earth Materials is a sophomore level course for Geoscience and Marine Science majors at Eckerd College. The Art for the Smart project leads into an assignment for the second half of the semester featuring building stones. A new "client" sends a letter to the class explaining

    Youngblood, J. N.; Welzyn, K. J.

    1986-01-01

    The work done to establish the control and direction of effective eigenvalue excursions of lightly damped, speed dependent rotor systems using passive control is discussed. Both second order and sixth order bi-axis, quasi-linear, speed dependent generic models were investigated. In every case a single, bi-directional control bearing was used in a passive feedback stabilization loop to resist modal destabilization above the rotor critical speed. Assuming incomplete state measurement, sub-optimal control strategies were used to define the preferred location of the control bearing, the most effective measurement locations, and the best set of control gains to extend the speed range of stable operation. Speed dependent control gains were found by Powell's method to maximize the minimum modal damping ratio for the speed dependent linear model. An increase of 300 percent in stable speed operation was obtained for the sixth order linear system using passive control. Simulations were run to examine the effectiveness of the linear control law on nonlinear rotor models with bearing deadband. The maximum level of control effort (force) required by the control bearing to stabilize the rotor at speeds above the critical was determined for the models with bearing deadband.

  1. A New Approach to Pointer Analysis for Assignments

    Institute of Scientific and Technical Information of China (English)

    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.

  3. Linear assignment maps for correlated system-environment states

    Energy Technology Data Exchange (ETDEWEB)

    Rodriguez-Rosario, Cesar A.; Modi, Kavan; Aspuru-Guzik, Alan

    2010-01-20

    Assignment maps are mathematical operators that describe initial system-environment states for open quantum systems. We re-examine the notion of assignments that account for correlations between the system and the environment and show that these maps can be made linear at the expense of giving up positivity or consistency of the map. We study the role of positivity and consistency of the map and show the effects of relaxing these. Finally, we establish a connection between the violation of the positivity of linear assignments and the no-broadcasting theorem.

    Röben, Marco; Schmieder, Peter

    2011-09-01

    A complete assignment of all resonances of a small organic molecule is a prerequisite for a structure determination using NMR spectroscopy. This is conventionally obtained using a well-established strategy based on COSY, HMQC and HMBC spectra. In case of phycocyanobilin (PCB) in HMPT this strategy was unsuccessful due to the symmetry of the molecule and extreme signal overlap. Since (13)C and (15)N labeled material was available, an alternative strategy for resonance assignment was used. Triple resonance experiments derived from experiments conventionally performed for proteins are sensitive and easy to analyze. Their application led to a complete and unambiguous assignment using three types of experiments. PMID:21815209

    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

    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.

    Directory of Open Access Journals (Sweden)

    JN Roux

    2007-12-01

    Full Text Available In a military environment an operator is typically required to evaluate the tactical situation in real-time and protect defended assets against enemy threats by assigning available weapon systems to engage enemy craft. This environment requires rapid operational planning and decision making under severe stress conditions, and the associated responsibilities are usually divided between a number of operators and computerized decision support systems that aid these operators during the decision making processes. The aim in this paper is to review the state of the art of this kind of threat evaluation and weapon assignment decision support process as it stands within the context of a ground based air defence system (GBADS at the turn of the twenty first century. However, much of the contents of the paper may be generalized to military environments other than a GBADS one.

    Global exponential stability is the most desirable stability property of recurrent neural networks. The paper presents new results for recurrent neural networks applied to online computation of feedback gains of linear time-invariant multivariable systems via pole assignment. The theoretical analysis focuses on the global exponential stability, convergence rates, and selection of design parameters. The theoretical results are further substantiated by simulation results conducted for synthesizing linear feedback control systems with different specifications and design requirements.

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

In this paper, a fleetassignment model is set up using the data of the largest Airline Company in Turkey, TurkishAirlines. The aim of this model is to assign the most appropriate fleet type to flights whileminimizing the cost and determining the optimal number of aircraft grounded overnight at eachairport. We set up a model with constraints with thinking all airline operations and solve ourproblem using integer linear programming. Finally, we get an optimum solution which minimizesthe total cost while assigning the fleet type to the flight leg. Using optimization software (Lindo6.1, the solution to this problem generates a minimum daily cost of fleet assignment.

    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.

  4. 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.

  8. A Semiautomated Assignment Protocol for Methyl Group Side Chains in Large Proteins.

    2016-01-01

    The developments of biosynthetic specific labeling strategies for side-chain methyl groups have allowed structural and dynamic characterization of very large proteins and protein complexes. However, the assignment of the methyl-group resonances remains an Achilles' heel for NMR, as the experiments designed to correlate side chains to the protein backbone become rather insensitive with the increase of the transverse relaxation rates. In this chapter, we outline a semiempirical approach to assign the resonances of methyl-group side chains in large proteins. This method requires a crystal structure or an NMR ensemble of conformers as an input, together with NMR data sets such as nuclear Overhauser effects (NOEs) and paramagnetic relaxation enhancements (PREs), to be implemented in a computational protocol that provides a probabilistic assignment of methyl-group resonances. As an example, we report the protocol used in our laboratory to assign the side chains of the 42-kDa catalytic subunit of the cAMP-dependent protein kinase A. Although we emphasize the labeling of isoleucine, leucine, and valine residues, this method is applicable to other methyl group side chains such as those of alanine, methionine, and threonine, as well as reductively methylated cysteine side chains.

  9. 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.

    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.

    Pointer analysis is a technique to identify at copile-time the potential values of the pointer expressions in a program,which promises significant benefits for optimzing and parallelizing complilers.In this paper,a new approach to pointer analysis for assignments is presented.In this approach,assignments are classified into three categories:pointer assignments,structure(union)assignents 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 assigemtn.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.

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

    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.

  13. The Pedagogical Anatomy of Peer-Assessment: Dissecting a peerScholar Assignment

    Full Text Available Peer-assessment is a process wherein students grade the work of their peers rather than relying on an expert. With the recent advent of online tools for peer-assessment [1] it is possible to utilize peer-assessment within any course context, even extremely large courses, with virtually no logistic or economic barriers. Given this potential for widespread use, the present paper highlights the pedagogical value of peer-assessment by breaking down a specific assignment and highlighting the manner in which the learning experienced by students maps onto prominent categorizations of strong pedagogy. We argue that peer-assessment provides a powerful compliment to multiple-choice testing by providing support for the sort of deep, critical and creative learning that is simply not possible to either encourage or assess via multiple- choice.

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

    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.

    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.

    Graduate medical students of India are taught Biochemistry by didactic lectures and they hardly get any opportunity to clarify their doubts and reinforce the concepts which they learn in these lectures. We used a combination of teaching-learning (T-L) methods (open book assignment followed by group tutorials) to study their efficacy in improving the learning outcome. About 143 graduate medical students were classified into low (75%: group 3, n = 46) achievers, based on their internal assessment marks. After the regular teaching module on the topics "Vitamins and Enzymology", all the students attempted an open book assignment without peer consultation. Then all the students participated in group tutorials. The effects on the groups were evaluated by pre and posttests at the end of each phase, with the same set of MCQs. Gain from group tutorials and overall gain was significantly higher in the low achievers, compared to other groups. High and medium achievers obtained more gain from open book assignment, than group tutorials. The overall gain was significantly higher than the gain obtained from open book assignment or group tutorials, in all three groups. All the three groups retained the gain even after 1 week of the exercise. Hence, optimal use of novel T-L methods (open book assignment followed by group tutorials) as revision exercises help in strengthening concepts in Biochemistry in this oft neglected group of low achievers in graduate medical education. © 2016 by The International Union of Biochemistry and Molecular Biology, 44(4):321-325, 2016.
