    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.

    The optimum time students should spend on homework has been widely researched although the results are far from unanimous. The main objective of this research is to analyze how homework assignment strategies in schools affect students' academic performance and the differences in students' time spent on homework. Participants were a representative sample of Spanish adolescents (N = 26,543) with a mean age of 14.4 (±0.75), 49.7% girls. A test battery was used to measure academic performance in four subjects: Spanish, Mathematics, Science, and Citizenship. A questionnaire allowed the measurement of the indicators used for the description of homework and control variables. Two three-level hierarchical-linear models (student, school, autonomous community) were produced for each subject being evaluated. The relationship between academic results and homework time is negative at the individual level but positive at school level. An increase in the amount of homework a school assigns is associated with an increase in the differences in student time spent on homework. An optimum amount of homework is proposed which schools should assign to maximize gains in achievement for students overall.

  9. 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.

  15. 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.

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

    Directory of Open Access Journals (Sweden)

    Theresa McDevitt

    2013-10-01

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

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

    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.

  18. "Failure to assign failing grades": issues with grading the unsafe student.

    Luhanga, Florence; Yonge, Olive J; Myrick, Florence

    2008-01-01

    In a grounded theory study examining the process of precepting an unsafe student, it was found that preceptors assigned passing grades to students who in fact should not have passed. Although preceptors perceived their role as gatekeepers for the profession, by not assigning failing grades to students who should not have passed a course, essentially they were abdicating their responsibility. Indeed, the simple act of assuming responsibility for precepting a student implies professional as well as pedagogical accountability.

  7. 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.

    McMillan, Libba Reed; Raines, Kimberly

    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.

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

    Directory of Open Access Journals (Sweden)

    Evelyn Kigozi Kahiigi

    2013-01-01

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

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

    Directory of Open Access Journals (Sweden)

    Ali Jabbar Al BAKAA

    2014-11-01

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

  17. 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.

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

    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

    Full Text Available The ability to understand and interpret data is a critical aspect of scientific thinking.  However, although data analysis is often a focus in biology majors classes, many textbooks for allied health majors classes are primarily content-driven and do not include substantial amounts of experimental data in the form of graphs and figures.  In a lower-division allied health majors microbiology class, students were exposed to data from primary journal articles as take-home assignments and their data analysis skills were assessed in a pre-/posttest format.  Students were given 3 assignments that included data analysis questions.  Assignments ranged from case studies that included a figure from a journal article to reading a short journal article and answering questions about multiple figures or tables.  Data were represented as line or bar graphs, gel photographs, and flow charts.  The pre- and posttest was designed incorporating the same types of figures to assess whether the assignments resulted in any improvement in data analysis skills.  The mean class score showed a small but significant improvement from the pretest to the posttest across three semesters of testing.  Scores on individual questions testing accurate conclusions and predictions improved the most.  This supports the conclusion that a relatively small number of out-of-class assignments through the semester resulted in a significant improvement in data analysis abilities in this population of students.

    2015-03-01

    To respond to widespread disparities in access to oral health care, the Institute of Medicine, the Commission on Dental Accreditation (CODA), and the U.S. surgeon general have stressed that prospective dentists should become culturally competent, socially responsible practitioners. The aim of this study was to examine linguistic differences in dental students' reflective writing assignments before and after interviewing an individual who was culturally different from themselves. The authors analyzed 160 documents from 80 first-year dental students at the University of Florida in 2012. This cohort consisted of 36 male (45%) and 44 female (55%) students; 26 (32%) were from underrepresented minority (URM) groups and 54 (68%) were identified as white non-minority. Text analysis software identified word counts, categories, frequencies, and contexts. Significantly positive differences occurred for interviews between assignments 1 and 2 (p=0.005 to pcultural diversity. Differences were observed for Factor 1 ("important others' influence") between assignments (p<0.001), assignments by interview categories (p=0.033), and URM/majority participants by assignments by interview category (p=0.018). Factor 4 ("my social world in relation to others") was statistically different between assignments for URM/majority participants (p=0.019). Factor 5 ("wrong because") was statistically different for gender (p=0.041), suggesting that males may have experienced a rebound effect from stereotype suppression. The findings suggest that the use of reflective writing and interviews affected the students' awareness of how important others had influenced their lives and attitudes and facilitated their questioning preconceived assumptions. Reactions to coursework focusing on social and personal domains warrant further investigation.

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

    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...

  7. Using student writing assignments to assess critical thinking skills: a holistic approach.

    Niedringhaus, L K

    2001-04-01

    This work offers an example of one school's holistic approach to the evaluation of critical thinking by using student writing assignments. Faculty developed tools to assess achievement of critical thinking competencies, such as analysis, synthesis, insight, reflection, open mindedness, and depth, breadth, and appropriateness of clinical interventions. Faculty created a model for the development of program-specific critical thinking competencies, selected appropriate writing assignments that demonstrate critical thinking, and implemented a holistic assessment plan for data collection and analysis. Holistic assessment involves the identification of shared values and practices, and the use of concepts and language important to nursing.

    2016-01-01

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

  9. Creative Writing Assignments in a Second Language Course: A Way to Engage Less Motivated Students

    Directory of Open Access Journals (Sweden)

    Ekaterina Arshavskaya, PhD

    2015-08-01

    Full Text Available This article makes a case for using creative writing in a second language course. Creative writing increases students’ enthusiasm for writing skills development and supports students’ creativity, which is a fundamental aspect of education. In order to engage less motivated students, a series of creative writing assignments was implemented in a second language writing course. This study presents the rationale for the use of creative writing grounded in critical pedagogy and the context of instruction. Data collection focused on the content of students’ writing and their attitudes towards creative writing and critical pedagogy. The results show that all the participating students found the assignment both enjoyable and beneficial for the development of their writing ability. However, the students’ perceptions of critical pedagogy varied. The author argues for greater employment of creative writing in second language courses in the future.

    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

    2011-01-01

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

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

    Directory of Open Access Journals (Sweden)

    Dragutin KERMEK

    2016-04-01

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

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

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

    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.

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

    Directory of Open Access Journals (Sweden)

    Kjrsten Keane

    2014-02-01

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

    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.

    Tinney, Charles Evan

    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

    2009-06-01

    The development of a personal philosophical statement about nursing is a useful assignment for both undergraduate and graduate nursing students. Students are asked to write a paper describing their philosophical views about nursing related to the metaparadigm concepts and include in-depth examples from their clinical practice to illustrate these views. This article includes information regarding important preparatory activities and handouts to facilitate the writing and evaluation of this assignment. There are many potential benefits of this complex assignment. It promotes students' reflection on their personal clinical practice experiences and engages students in mental and verbal dialogue that elicits their philosophical ideas about the metaparadigm concepts. These activities promote critical thinking and reflective clinical practice, act as a foundation for building theoretical understanding, and promote confidence in learning about nursing and other theories.

    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.

  17. 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.

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

    2016-01-01

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

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

    Science.gov (United States)

    Werth, Arman Karl

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

  18. Online supervision at the university - A comparative study of supervision on student assignments face-to-face and online

    Directory of Open Access Journals (Sweden)

    Søren Smedegaard Bengtsen

    2015-09-01

    Full Text Available Through an empirical study of supervision on student assignments at the university across face-to-face and online settings, we show firstly the limiting implications of traditional dichotomies between face-to-face and online supervision. Secondly we show that more attention must be given to the way different digital tools influence the supervisory dialogue. These findings illustrate a form of ‘torn pedagogy’; that online tools and platforms destabilize and tear traditional understandings of supervision pedagogy apart. Also we forge a new concept of “format supervision” that enables supervisors to understand and reflect their supervision practice as a deliberate choice between face-to-face and online formats.

  8. 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.

    Science.gov (United States)

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

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

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

    Science.gov (United States)

    Varghese, Joe; Jacob, Molly

    2015-01-01

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

    A new grading system is presented for evaluating and grading dental students' clinical competence and performance in paediatric dentistry at the undergraduate level. The Flexible Requirements System is a clinical competence evaluation system designed to address some of the common deficiencies of other requirements-based performance evaluation systems, by utilising a unique method of collecting and manipulating certain measurements of student performance in various groups of clinical procedures. The system aimed to incorporate adequate flexibility in its requirements to afford students fair and equal opportunities, whilst maintaining adherence to departmental clinical competence criteria and standards.

  12. A focused assignment encouraging deep reading in undergraduate biochemistry.

    Science.gov (United States)

    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.

    Smit, Jantien; Bakker, Arthur; van Eerde, Dolly; Kuijpers, Maggie

    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.

  1. GRE requirements and student perceptions of fictitious clinical psychology graduate programs.

    Atwood, Karen L; Manago, Adriana M; Rogers, Ronald F

    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.

    Scharfenberg, Franz-Josef; Bogner, Franz X.

    2013-02-01

    This study classified students into different cognitive load (CL) groups by means of cluster analysis based on their experienced CL in a gene technology outreach lab which has instructionally been designed with regard to CL theory. The relationships of the identified student CL clusters to learner characteristics, laboratory variables, and cognitive achievement were examined using a pre-post-follow-up design. Participants of our day-long module Genetic Fingerprinting were 409 twelfth-graders. During the module instructional phases (pre-lab, theoretical, experimental, and interpretation phases), we measured the students' mental effort (ME) as an index of CL. By clustering the students' module-phase-specific ME pattern, we found three student CL clusters which were independent of the module instructional phases, labeled as low-level, average-level, and high-level loaded clusters. Additionally, we found two student CL clusters that were each particular to a specific module phase. Their members reported especially high ME invested in one phase each: within the pre-lab phase and within the interpretation phase. Differentiating the clusters, we identified uncertainty tolerance, prior experience in experimentation, epistemic interest, and prior knowledge as relevant learner characteristics. We found relationships to cognitive achievement, but no relationships to the examined laboratory variables. Our results underscore the importance of pre-lab and interpretation phases in hands-on teaching in science education and the need for teachers to pay attention to these phases, both inside and outside of outreach laboratory learning settings.

    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.

    2006-05-01

    The aim of the present study was to investigate whether basic scientists and physicians agree on the required depth of biomedical knowledge of medical students at graduation. A selection of basic science and clinical teachers rated the relevance of biomedical topics for students at graduation, illustrated by 80 example items. The items were derived from ten organ systems and designed at four levels: clinical, organ, cellular and molecular. Respondents were asked to identify for each item to what extent recently graduated medical students should have knowledge about it. In addition, they were asked to indicate whether the content of the item should be included in the medical curriculum. Analysis showed that basic scientists and physicians do not diverge at the clinical level. At the organ, cellular and molecular levels however, basic scientists judge that medical students should have more active knowledge. As expected, basic scientists also indicate that more deep level content should be included. Explanations for this phenomenon will be discussed.

    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.

    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.

  7. 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.

    Science.gov (United States)

    Potvin, Patrice; Turmel, Elaine; Masson, Steve

    2014-01-01

    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 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.

  11. 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.

  12. Automatic Assessment of Programming assignment

    Directory of Open Access Journals (Sweden)

    2012-01-01

    Full Text Available In today’s world study of computer’s language is more important. Effective and good programming skills are need full all computer science students. They can be master in programming, only through intensive exercise practices. Due to day by day increasing number of students in the class, the assessment of programming exercises leads to extensive workload for teacher/instructor, particularly if it has to be carried out manually. In this paper, we propose an automatic assessment system for programming assignments, using verification program with random inputs. One of the most important properties of a program is that, it carries out its intended function. The intended function of a program or part of a program can be verified by using inverse function’s verification program. For checking intended functionality and evaluation of a program, we have used verification program. This assessment system has been tested on basic C programming courses, and results shows that it can work well in basic programming exercises, with some initial promising results

    1993-12-01

    A new integrated computer-assisted personalized assignment (CAPA) system that creates individual assignments for each student has been developed and found to be a powerful motivator. The CAPA system allows students to enter their answers to personalized assignments directly via networked terminals, gives immediate feedback and hints (allowing challenging questions), while providing the instructor with on-line performance information. The students are encouraged to study together which is known to be an effective learning strategy, but each must still obtain his/her own correct answers. Students are allowed to re-enter solutions to the problems before the due date without penalty, thus providing students with different skills levels the opportunity and incentive to understand the material without being judged during the learning process. The features and operation of the system are described, observations on its use in an introductory general physics class are reported, and some of the highly favorable student reactions are included.

    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.

    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.

  5. 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...

  6. Traffic-Aware Channel Assignment in Wireless Sensor Networks

    Science.gov (United States)

    Wu, Yafeng; Keally, Matthew; Zhou, Gang; Mao, Weizhen

    Existing frequency assignment efforts in wireless sensor network research focus on balancing available physical frequencies among neighboring nodes, without paying attention to the fact that different nodes have different traffic volumes. Ignoring the different traffic requirements in different nodes in frequency assignment design leads to poor MAC performance. Therefore, in this paper, we are motivated to propose traffic-aware frequency assignment, which considers nodes’ traffic volumes when making frequency decisions. We incorporate our traffic-aware frequency assignment design into an existing multi-channel MAC, and compare the performance with two conventional frequency assignment schemes. Our performance evaluation demonstrates that traffic-aware channel assignment can greatly improve multi-channel MAC performance. Our traffic-aware assignment scheme greatly enhances the packet delivery ratio and system throughput, while reducing channel access delay and energy consumption.

  17. Career attitudes of first-year veterinary students before and after a required course on veterinary careers.

    Science.gov (United States)

    Fish, Richard E; Griffith, Emily H

    2014-01-01

    Careers in Veterinary Medicine is a required, one-credit-hour course at the North Carolina State University College of Veterinary Medicine (NCSU-CVM), which meets once weekly during veterinary students' first semester. Lectures in this course are presented by one or more veterinarians representing diverse career areas. A voluntary, anonymous survey was distributed before the first class meeting in 2011 (PRE) and at the end of the semester (POST) to assess if students' career interests changed during the semester. The survey collected basic demographic data and students' preferences (on a Likert scale) for 17 veterinary career paths. Out of 63 students, 36 (57%) in the POST survey said that their career interests had changed during the semester, and 17 of the 26 students (65%) who gave a reason credited the careers course as one factor in reconsidering their career choice. Only 3 of the 17 career paths had statistically significant PRE/POST survey differences in Likert response frequency (equine practice, pathology, and wildlife medicine), but both informal discussions with students and responses to open-ended survey questions indicated that many students valued the introduction to unfamiliar veterinary career areas. Careers in Veterinary Medicine is a vital component of recent career-planning initiatives in the college, which will be especially important to veterinary students as they face continued changes in the profession, such as the increased debt load of the new graduate and the threat of veterinary workforce oversupply.

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

    Science.gov (United States)

    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.

    个性化作业设计是指教师根据不同学生的个性特征、爱好和能力,设计内容、数量、要求和形式各不相同的作业的一种教学方法。以41位中学八年级学生为研究被试,采用实验法、问卷调查法、数理统计法等,对个性化作业设计提高中学生语文学习能力的效果进行教学检验,结果显示院采用个性化作业设计的教学实验后,被试学生的“文本鉴赏能力”、“口头表达能力”和“写作能力”得分较实验前的差异具有显著性,“阅读能力”得分差异具有高度的显著性;效应量分析的结果显示“个性化作业设计”对上述四个维度均具有中等规模的影响。认为院“个性化作业设计”有利于提高中学生的语文学习能力。%Individualized assignment design refers to the teaching method in which the teacher designs assignments with different contents, quantities and forms in accordance with students' dif-ferent personality characteristics, interests and abilities. With 41 Grade 8 students as the research object, the methods of experi-ment, questionnaire survey and mathematical statistics were tak-en to test the effect of improving middle school students' Chinese learning ability by individualized assignment design. The result shows that, after the experiment, the participants' scores of"text appreciation ability","spoken expression ability"and"writing a-bility"are significantly improved compared with those before the experiment; the result of effect analysis shows that "individual-ized assignment design"is of medium influence on the above four dimensions. The writer comes to the conclusion that"individual-ized assignment design"is conducive to the improvement of mid-dle school students' Chinese learning ability.

    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.

    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.

    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.

  8. 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

  20. Gene family assignment-free comparative genomics

    Directory of Open Access Journals (Sweden)

    Doerr Daniel

    2012-12-01

    Full Text Available Abstract Background The comparison of relative gene orders between two genomes offers deep insights into functional correlations of genes and the evolutionary relationships between the corresponding organisms. Methods for gene order analyses often require prior knowledge of homologies between all genes of the genomic dataset. Since such information is hard to obtain, it is common to predict homologous groups based on sequence similarity. These hypothetical groups of homologous genes are called gene families. Results This manuscript promotes a new branch of gene order studies in which prior assignment of gene families is not required. As a case study, we present a new similarity measure between pairs of genomes that is related to the breakpoint distance. We propose an exact and a heuristic algorithm for its computation. We evaluate our methods on a dataset comprising 12 γ-proteobacteria from the literature. Conclusions In evaluating our algorithms, we show that the exact algorithm is suitable for computations on small genomes. Moreover, the results of our heuristic are close to those of the exact algorithm. In general, we demonstrate that gene order studies can be improved by direct, gene family assignment-free comparisons.

    Directory of Open Access Journals (Sweden)

    Lyn Brodie

    2011-05-01

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

    2006-10-01

    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.

  11. 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.

    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.

  13. Predicting the academic success of architecture students by pre-enrolment requirement: using machine-learning techniques

    Directory of Open Access Journals (Sweden)

    Ralph Olusola Aluko

    2016-12-01

    Full Text Available In recent years, there has been an increase in the number of applicants seeking admission into architecture programmes. As expected, prior academic performance (also referred to as pre-enrolment requirement is a major factor considered during the process of selecting applicants. In the present study, machine learning models were used to predict academic success of architecture students based on information provided in prior academic performance. Two modeling techniques, namely K-nearest neighbour (k-NN and linear discriminant analysis were applied in the study. It was found that K-nearest neighbour (k-NN outperforms the linear discriminant analysis model in terms of accuracy. In addition, grades obtained in mathematics (at ordinary level examinations had a significant impact on the academic success of undergraduate architecture students. This paper makes a modest contribution to the ongoing discussion on the relationship between prior academic performance and academic success of undergraduate students by evaluating this proposition. One of the issues that emerges from these findings is that prior academic performance can be used as a predictor of academic success in undergraduate architecture programmes. Overall, the developed k-NN model can serve as a valuable tool during the process of selecting new intakes into undergraduate architecture programmes in Nigeria.

    In the past 10 years increased importance has been placed on public participation and environmental concerns in transportation system decision-making. While there are numerous societal objectives to consider when planning and operating a transportation system, it is not clear whether the optimal strategy with respect to one objective is also the optimal strategy with respect to the other objectives. This paper examines how new objectives and environmental considerations can be modeled within the traditional, macroscopic traffic assignment methodology. In addition, a new methodology for modeling the assignment of vehicles in realistic networks is developed based on equitable, rather than user-equilibrium or system-optimal, principles. The basic premise is that with the advent of intelligent transportation systems (ITS) the operation of the transportation system based on the objectives of the general public, rather than the traveling public and system operators, is feasible. A methodology for modeling these situations is required. All of the approaches discussed here were tested on a calibrated network from Edmonton, Alberta, Canada.

  16. 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.

    Paul, Gerald; Shao, Jia; Stanley, H. Eugene

    2011-11-01

    The quadratic assignment problem, QAP, is one of the most difficult of all combinatorial optimization problems. Here, we use an abbreviated application of the statistical mechanics replica method to study the asymptotic behavior of instances in which the entries of at least one of the two matrices that specify the problem are chosen from a random distribution P. Surprisingly, the QAP has not been studied before using the replica method despite the fact that the QAP was first proposed over 50 years ago and the replica method was developed over 30 years ago. We find simple forms for C min and C max , the costs of the minimal and maximum solutions respectively. Notable features of our results are the symmetry of the results for C min and C max and their dependence on P only through its mean and standard deviation, independent of the details of P.

    2012-05-01

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

  19. Practical Homework Assignments As Part Of Chemistry Teaching And Learning

    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:

  7. assignFAST: An Autosuggest based tool for FAST Subject Assignment

    Directory of Open Access Journals (Sweden)

    Rick Bennett

    2014-03-01

    Full Text Available Subject assignment is really a three-phase task. The first phase is intellectual—reviewing the material and determining its topic. The second phase is more mechanical, identifying the correct subject heading(s.  The final phase is retyping or cutting and pasting the heading(s into the cataloging interface along with any diacritics, and potentially correcting formatting and subfield coding. If authority control is available in the interface, some of these tasks may be automated or partially automated. A cataloger with a reasonable knowledge of FAST[i],[ii] or even LCSH[iii] can quickly get to the proper heading, but usually needs to confirm the final details—was it plural? Am I thinking of an alternate form? Is it inverted? Etc. This often requires consulting the full authority file interface. assignFAST is a Web service that consolidates the entire second phase of the manual process of subject assignment for FAST subjects into a single step based on autosuggest technology.

  12. 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

  14. Stereospecific assignments in proteins using exact NOEs

    2013-10-18

    Recently developed methods to measure distances in proteins with high accuracy by “exact” nuclear Overhauser effects (eNOEs) make it possible to determine stereospecific assignments, which are particularly important to fully exploit the accuracy of the eNOE distance measurements. Stereospecific assignments are determined by comparing the eNOE-derived distances to protein structure bundles calculated without stereospecific assignments, or an independently determined crystal structure. The absolute and relative CYANA target function difference upon swapping the stereospecific assignment of a diastereotopic group yields the respective stereospecific assignment. We applied the method to the eNOE data set that has recently been obtained for the third immunoglobulin-binding domain of protein G (GB3). The 884 eNOEs provide relevant data for 47 of the total of 75 diastereotopic groups. Stereospecific assignments could be established for 45 diastereotopic groups (96 %) using the X-ray structure, or for 27 diastereotopic groups (57 %) using structures calculated with the eNOE data set without stereospecific assignments, all of which are in agreement with those determined previously. The latter case is relevant for structure determinations based on eNOEs. The accuracy of the eNOE distance measurements is crucial for making stereospecific assignments because applying the same method to the traditional NOE data set for GB3 with imprecise upper distance bounds yields only 13 correct stereospecific assignments using the X-ray structure or 2 correct stereospecific assignments using NMR structures calculated without stereospecific assignments.

    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.

  8. 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

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

    Directory of Open Access Journals (Sweden)

    Anson Brown

    2014-02-01

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

  19. 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.

    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.

    2012-01-01

    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。

We prove that, when the reference vector is in the core of the game, the derived game is the super additive cover o...

  12. Dynamic Assignment in Microsimulations of Pedestrians

    CERN Document Server

    Kretz, Tobias; Hofsäß, Ingmar; Leonhardt, Axel

    2014-01-01

    A generic method for dynamic assignment used with microsimulation of pedestrian dynamics is introduced. As pedestrians - unlike vehicles - do not move on a network, but on areas they in principle can choose among an infinite number of routes. To apply assignment algorithms one has to select for each OD pair a finite (realistically a small) number of relevant representatives from these routes. This geometric task is the main focus of this contribution. The main task is to find for an OD pair the relevant routes to be used with common assignment methods. The method is demonstrated for one single OD pair and exemplified with an example.

  20. Crosstalk-Aware Routing Resource Assignment

    Institute of Scientific and Technical Information of China (English)

    Hai-Long Yao; Yi-Ci Cai; Qiang Zhou; Xian-Long Hong

    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.

  4. 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.

    2014-01-01

    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.

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

    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".

    2015-03-01

    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.

    2015-04-01

    Given the psychological and financial costs involved with failing a clinical course, especially in developing countries, an alternative educational method was tested with students who had to repeat the year-long endodontic course at the University of Chile Faculty of Dentistry. The objectives of the intervention were to deepen theoretical knowledge and practical experiences, as well as to reinforce personal confidence in an endodontic clinical setting for students who failed the regular endodontic course. The aim of this study was to evaluate the success of this new model of educational intervention. In the study, 28 students who had failed the endodontic course repeated it with an alternative teaching method. The students attended patients immediately following practical competence exams, and they had access to simulated models that used rotary instruments and access cavities and had emergency care practice. Feedback sessions were held after each clinical session. Final grades were compared with those of other students who repeated the course without the intervention from 2007 to 2009. A survey was administered to understand the causes of initial failure and their opinions of the intervention. Students who participated in the alternative course did significantly better than their counterparts from previous years who did not receive the intervention (5.7±0.3 vs. 5.4±0.2; pendodontics, a contrasting perspective to the frustration students usually express after repeating the course. The results of this study support the introduction of similar interventions in endodontics and perhaps other courses.

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

  13. 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.

    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.

  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.

  19. Improving active eigenvector assignment through passive modifications

    Science.gov (United States)

    Belotti, R.; Richiedei, D.

    2016-09-01

    Specifications on the dynamic behavior of feedback-controlled vibrating systems are often expressed in terms of its eigenstructure, i.e. eigenvalues and eigenvectors. The notion of controllability establishes the possibility to assign eigenvalues through state feedback, but it is not adequate to assure the assignment of arbitrary eigenvectors. Indeed, assignable eigenvectors are just those belonging to the allowable vector subspace, which depends on the physical properties of the vibrating system (mass, damping and stiffness matrices) and of the actuators. To overcome this limitation, this paper proposes a hybrid approach that exploits passive modification of the system physical parameters to modify the allowable subspace in such a way that it spans (or closely approximates) the desired eigenvectors. Then, once that the system modifications have been computed, standard techniques for control synthesis can be employed to compute the gains assigning the desired poles and the eigenvectors. The modification of the allowable subspace is cast in this work as a rank minimization problem, which can be efficiently tackled through semi-definite programming. The proposed method is numerically validated on a lumped parameter system, by proving that the assignment of eigenvectors by hybrid control is significantly enhanced compared with sole active control.

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.

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

    Energy Technology Data Exchange (ETDEWEB)

    Holter, G.M.; Purcell, W.L.; Shutz, M.E.; Young, J.R.

    1986-07-01

    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.

  2. Scalable Task Assignment for Heterogeneous Multi-Robot Teams

    Full Text Available This work deals with the development of a dynamic task assignment strategy for heterogeneous multi‐robot teams in typical real world scenarios. The strategy must be efficiently scalable to support problems of increasing complexity with minimum designer intervention. To this end, we have selected a very simple auction‐based strategy, which has been implemented and analysed in a multi‐robot cleaning problem that requires strong coordination and dynamic complex subtask organization. We will show that the selection of a simple auction strategy provides a linear computational cost increase with the number of robots that make up the team and allows the solving of highly complex assignment problems in dynamic conditions by means of a hierarchical sub‐auction policy. To coordinate and control the team, a layered behaviour‐based architecture has been applied that allows the reusing of the auction‐based strategy to achieve different coordination levels.

  3. Pole assignment for stochastic systems with unknown coefficients

    Institute of Scientific and Technical Information of China (English)

    陈翰馥[1; 曹希仁[2

    2000-01-01

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

  5. Demand assignment in the ACTS LBR system

    Science.gov (United States)

    Palmer, Larry C.; White, Lawrence W.

    1990-05-01

    On the Advanced Communications Technology Satellite (ACTS) being developed at NASA Lewis, low-burst-rate (LBR) traffic stations will access the ACTS multibeam package via two hopping beams that can be directed at certain areas in the continental U.S. An onboard baseband processor (BBP) demodulates uplink traffic, switches it between uplink and downlink beams at baseband, and then remodulates it for retransmission at 20 GHz. This study describes the demand-assigned operation of the ACTS LBR system, where the onboard switch is remote from both traffic stations and master control station (MCS). Network control uses inbound and outbound orderwire channels and a BBP control channel, allowing the MCS to coordinate assignment of individual 64-kb/s spacecraft channels. Models are developed to simulate the dynamics of the assignment process and verify the call blocking behavior, to predict control channel loads, and to evaluate algorithms for burst time plan rearrangement.

  6. The Wiener maximum quadratic assignment problem

    Cela, Eranda; Woeginger, Gerhard J

    2011-01-01

    We investigate a special case of the maximum quadratic assignment problem where one matrix is a product matrix and the other matrix is the distance matrix of a one-dimensional point set. We show that this special case, which we call the Wiener maximum quadratic assignment problem, is NP-hard in the ordinary sense and solvable in pseudo-polynomial time. Our approach also yields a polynomial time solution for the following problem from chemical graph theory: Find a tree that maximizes the Wiener index among all trees with a prescribed degree sequence. This settles an open problem from the literature.

  7. Evolving Networks with Nonlinear Assignment of Weight

    Institute of Scientific and Technical Information of China (English)

    TANG Chao; TANG Yi

    2006-01-01

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

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

    Institute of Scientific and Technical Information of China (English)

    万海; 李文军

    2007-01-01

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

  7. Pole Assignment for Second-Order Systems

    Science.gov (United States)

    CHU, E. K.

    2002-01-01

    This paper contains some results for pole assignment problems for the second-order system M ẍ(t)+D ẋ(t)+K x (t)=B u (t) . Specifically, Algorithm 0 constructs feedback matrices F1 and F2 such that the closed-loop quadratic pencil Pc( λ)= λ2M+ λ ( D+ BF2)+( K+ BF1) has a desired set of eigenvalues and the associated eigenvectors are well-conditioned. The method is a modification of the SVD-based method proposed by Juang and Maghami [1, 2] which is a second-order adaptation of the well-known robust eigenvalue assignment method by Kautsky et al. [3] for first-order systems. Robustness is achieved by minimising some not-so-well-known condition numbers of the eigenvalues of the closed-loop second-order pencil. We next consider the partial pole assignment problem. In 1997, Datta, Elhay and Ram proposed three biorthogonality relations for eigenvectors of symmetric definite quadratic pencils [4]. One of these relations was used to derive an explicit solution to the partial pole assignment problem by state feedback for the related single-input symmetric definite second-order control system. The solution shed new light on the stabilisation and control of large flexible space structures, for which only one small subset of the spectrum needs to be reassigned while retaining the complementary part of the spectrum. In this paper, the method has been generalised for multi-input and non-symmetric quadratic pencils. Finally, we discuss briefly the output feedback pole assignment problem.

  11. 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.

    Hunt, Carl E; Darnall, Robert A; McEntire, Betty L; Hyma, Bruce A

    2015-06-01

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

  3. Pole assignment in descriptor periodic systems

    Institute of Scientific and Technical Information of China (English)

    FAN; Hung-Yuan; LIN; Wen-Wei; XU; Shufang

    2005-01-01

    In this paper a pole assignment problem is considered for the descriptor linear discrete-time periodic systems, which is using the periodic proportional-derivative feedback to modify a given system such that the closed loop system has a specified selfconjugate set of eigenvalues. It is shown that the complete reachability of an open loop periodic system is equivalent to the possibility of assigning an arbitrary set of the eigenvalues to the system by choosing the suitable periodic proportional-derivative feedback.A computational approach is also proposed to solve the problem, which uses the reliable numerical techniques based on the orthogonal transformations. Numerical examples are presented to illustrate the effectiveness of the proposed approach.

    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.

  5. Online Assignment Algorithms for Dynamic Bipartite Graphs

    CERN Document Server

    2011-01-01

    This paper analyzes the problem of assigning weights to edges incrementally in a dynamic complete bipartite graph consisting of producer and consumer nodes. The objective is to minimize the overall cost while satisfying certain constraints. The cost and constraints are functions of attributes of the edges, nodes and online service requests. Novelty of this work is that it models real-time distributed resource allocation using an approach to solve this theoretical problem. This paper studies variants of this assignment problem where the edges, producers and consumers can disappear and reappear or their attributes can change over time. Primal-Dual algorithms are used for solving these problems and their competitive ratios are evaluated.

A publisher who has already signed contracts reserving advertisement impressions on his pages can choose between assigning a new ad impression for a new page view to a contracted advertiser or to sell it at an ad exchange. This leads to an online revenue maximization problem for the publisher. Given a new impression to sell decide whe...

    Chicano, Francisco; Alba, Enrique

    2011-01-01

    The Quadratic Assignment Problem (QAP) is a well-known NP-hard combinatorial optimization problem that is at the core of many real-world optimization problems. We prove that QAP can be written as the sum of three elementary landscapes when the swap neighborhood is used. We present a closed formula for each of the three elementary components and we compute bounds for the autocorrelation coefficient.

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

  15. Accurate taxonomic assignment of short pyrosequencing reads.

    Clemente, José C; Jansson, Jesper; Valiente, Gabriel

    2010-01-01

    Ambiguities in the taxonomy dependent assignment of pyrosequencing reads are usually resolved by mapping each read to the lowest common ancestor in a reference taxonomy of all those sequences that match the read. This conservative approach has the drawback of mapping a read to a possibly large clade that may also contain many sequences not matching the read. A more accurate taxonomic assignment of short reads can be made by mapping each read to the node in the reference taxonomy that provides the best precision and recall. We show that given a suffix array for the sequences in the reference taxonomy, a short read can be mapped to the node of the reference taxonomy with the best combined value of precision and recall in time linear in the size of the taxonomy subtree rooted at the lowest common ancestor of the matching sequences. An accurate taxonomic assignment of short reads can thus be made with about the same efficiency as when mapping each read to the lowest common ancestor of all matching sequences in a reference taxonomy. We demonstrate the effectiveness of our approach on several metagenomic datasets of marine and gut microbiota.

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

    Science.gov (United States)

    Shibata, Kazuaki; Horio, Yoshihiko; Aihara, Kazuyuki

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

    2010-01-01

    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

    2013-12-01

    It is known that assessment drives learning and hence a good assessment design is key to effective student development. This paper gives some case studies in effective assessment strategies within engineering. The main contribution is to demonstrate how one can simultaneously meet a number of requirements with individual assessments and therefore be efficient in both the student and staff assessment load. The paper also proposes that assessments should be challenging and the benefits of expecting students to rise to this challenge and also how one can meet many independent learning objectives in a single assignment in order to manage the overall assessment load for staff and students.

    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.

    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.

    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.

    Full Text Available This study explored students’ perceptions and behaviors of public wiki use during a collaborative Wikipedia assignment in a graduate technology and literacy education course. Results confirmed that the majority of students had an overall positive experience posting content on Wikipedia. Students learned how to use Wikipedia through collaborative practice, including, how to adhere to its standards and cite work properly, the importance of critically evaluating online information, and the value of publishing work to an authentic audience. Students (prospective and current teachers reported numerous ways in which collaboration on Wikipedia could be integrated into their K-12 classrooms in order to promote higher order thinking and foster meaningful knowledge construction. Pedagogical practices for the effective integration of public wiki assignments in higher education and K-12 settings are recommended.

    2004-01-01

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

    In this paper, we discuss analog neural approaches to the quadratic assignment problem (QAP). These approaches employ a hard constraints scheme to restrict the domain space, and are able to obtain much improved solutions over conventional neural approaches. Since only a few strong heuristics for QAP have been known to date, our approaches are good alternatives, capable of obtaining fairly good solutions in a short period of time. Some of them can also be applied to large-scale problems, say of size N>/=300.

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

    Directory of Open Access Journals (Sweden)

    Avtar Singh Buttar

    2013-03-01

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

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

    Directory of Open Access Journals (Sweden)

    Fang Ye

    2011-06-01

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

  19. Dynamic assignment: there is an equilibrium !

    CERN Document Server

    Meunier, Frédéric

    2008-01-01

    Given a network with a continuum of users at some origins, suppose that the users wish to reach specific destinations, but that they are not indifferent to the time needed to reach their destination. They may have several possibilities (of routes or deparure time), but their choices modify the travel times on the network. Hence, each user faces the following problem: given a pattern of travel times for the different possible routes that reach the destination, find a shortest path. The situation in a context of perfect information is a so-called Nash equilibrium, and the question whether there is such an equilibrium and of finding it if it exists is the so-called equilibrium assignment problem. It arises for various kind of networks, such as computers, communication or transportation network. When each user occupies permanently the whole route from the origin to its destination, we call it the static assignment problem, which has been extensively studied with pioneers works by Wardrop or Beckmann. A less studi...

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

  1. A Review on Quantitative Approaches for Dock Door Assignment in Cross-Docking

    Directory of Open Access Journals (Sweden)

    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.

  3. Bayesian selection of nucleotide substitution models and their site assignments.

    Wu, Chieh-Hsi; Suchard, Marc A; Drummond, Alexei J

    2013-03-01

    Probabilistic inference of a phylogenetic tree from molecular sequence data is predicated on a substitution model describing the relative rates of change between character states along the tree for each site in the multiple sequence alignment. Commonly, one assumes that the substitution model is homogeneous across sites within large partitions of the alignment, assigns these partitions a priori, and then fixes their underlying substitution model to the best-fitting model from a hierarchy of named models. Here, we introduce an automatic model selection and model averaging approach within a Bayesian framework that simultaneously estimates the number of partitions, the assignment of sites to partitions, the substitution model for each partition, and the uncertainty in these selections. This new approach is implemented as an add-on to the BEAST 2 software platform. We find that this approach dramatically improves the fit of the nucleotide substitution model compared with existing approaches, and we show, using a number of example data sets, that as many as nine partitions are required to explain the heterogeneity in nucleotide substitution process across sites in a single gene analysis. In some instances, this improved modeling of the substitution process can have a measurable effect on downstream inference, including the estimated phylogeny, relative divergence times, and effective population size histories.

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

    Science.gov (United States)

    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

  5. INDEXING WORKSHOP: HOW TO ASSIGN KEYWORDS

    Energy Technology Data Exchange (ETDEWEB)

    Sternberg, Virginia

    1979-09-01

    You have heard about issues surrounding indexing and retrieval of nuclear records and automation and micrographics of these records. Now we are going to get each of you involved in indexing and assigning keywords. The first part of this hands-on workshop will be a very basic, elementary step-by-step introduction, concentrating on how to assign keywords. It is a workshop for beginners, People who have never done it before. It is planned to demonstrate what an analyst has to do to index and assign keywords to a document. Then I will take some pages of a report and demonstrate how I choose keywords for it. Then each of you will have a chance to do the same thing with similar pages from another report. Then we will discuss the variations ln the keywords you individually assigned. There are many systems that can be used. In this particular workshop we will cover only a system of building your own keyword listing as you index your documents. We will be discussing keywords or descriptors or subject words, but first I want to point out a few other critical points about indexing. When developing an indexing project the most important thing to do first lS decide what elements you want to retrieve by. Whether you go into a large computer retrieval system or a small three-by-five card system, you have to decide in advance what you want to retrieve. Then you can go on from there. If you only need to search by equipment number or by purchase order or by contract number, then you can use a very simple retrieval system. But if you want to be able to retrieve a record by any combination of elements, then you have to consistently input these into your system. For example, if you want to be able to ask for the drawings of the piping in the secondary cooling system, level 3, manufactured by a certain vendor, then you must have put the information into the index by a retrieval file point, in advance. I want to stress that the time spent in deciding what has to be retrievable is never

    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.

    Huang, Zhoudi; Wei, Zhenzhong; Zhang, Guangjun

    2016-10-01

    Constructing robust binary local feature descriptors are receiving increasing interest due to their binary nature, which can enable fast processing while requiring significantly less memory than their floating-point competitors. To bridge the performance gap between the binary and floating-point descriptors without increasing the computational cost of computing and matching, optimal binary weights are learning to assign to binary descriptor for considering each bit might contribute differently to the distinctiveness and robustness. Technically, a large-scale regularized optimization method is applied to learn float weights for each bit of the binary descriptor. Furthermore, binary approximation for the float weights is performed by utilizing an efficient alternatively greedy strategy, which can significantly improve the discriminative power while preserve fast matching advantage. Extensive experimental results on two challenging datasets (Brown dataset and Oxford dataset) demonstrate the effectiveness and efficiency of the proposed method.

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

    Directory of Open Access Journals (Sweden)

    Marcele Elisa Fontana

    2013-08-01

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

  20. A Hybrid Model for Making Online Assignments Effective In a Traditional Classroom

    Directory of Open Access Journals (Sweden)

    Ronda Sturgill

    2011-04-01

    Full Text Available Today’s college student has grown up in a world filled with technology and many current college students routinely utilize the latest and most up to date forms of technology. The result is an ever-changing way of communicating between faculty members and students. Many faculty members, however, are intimidated by the use of the terms “technology”, “online” and “distance education.” This often results in a communication gap between faculty and students where faculty members will “lose” students on the first day of class. Advantages of incorporating online tools into the course structure include freeing up additional class time, enhancing classroom discussions, and allowing students to remain current with information in their field. This hybrid instructional model focuses on the integration of technology tools as a supplement to traditional classroom teaching. This paper will describe how to effectively incorporate and implement technology using online course tools in a traditional classroom setting. Specific examples of online assignments, discussions, and assessments from an allied health education program and class will be discussed. Lessons learned and challenges confronted when adapting to the utilization of specific online course assignments and tools will be discussed.

  1. Using rule-based shot dose assignment in model-based MPC applications

    Science.gov (United States)

    Bork, Ingo; Buck, Peter; Wang, Lin; Müller, Uwe

    2014-10-01

    Shrinking feature sizes and the need for tighter CD (Critical Dimension) control require the introduction of new technologies in mask making processes. One of those methods is the dose assignment of individual shots on VSB (Variable Shaped Beam) mask writers to compensate CD non-linearity effects and improve dose edge slope. Using increased dose levels only for most critical features, generally only for the smallest CDs on a mask, the change in mask write time is minimal while the increase in image quality can be significant. This paper describes a method combining rule-based shot dose assignment with model-based shot size correction. This combination proves to be very efficient in correcting mask linearity errors while also improving dose edge slope of small features. Shot dose assignment is based on tables assigning certain dose levels to a range of feature sizes. The dose to feature size assignment is derived from mask measurements in such a way that shape corrections are kept to a minimum. For example, if a 50nm drawn line on mask results in a 45nm chrome line using nominal dose, a dose level is chosen which is closest to getting the line back on target. Since CD non-linearity is different for lines, line-ends and contacts, different tables are generated for the different shape categories. The actual dose assignment is done via DRC rules in a pre-processing step before executing the shape correction in the MPC engine. Dose assignment to line ends can be restricted to critical line/space dimensions since it might not be required for all line ends. In addition, adding dose assignment to a wide range of line ends might increase shot count which is undesirable. The dose assignment algorithm is very flexible and can be adjusted based on the type of layer and the best balance between accuracy and shot count. These methods can be optimized for the number of dose levels available for specific mask writers. The MPC engine now needs to be able to handle different dose

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

    Science.gov (United States)

    Pascarella, Andrea M.

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

  3. Using interviews to understand the assignment mechanism in a nonexperimental study: the case of eighth grade algebra.

    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.

  4. 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.

    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.

    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.

    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.

    Nuclear magnetic resonance (NMR) spectroscopy is an important experimental technique that allows one to study protein structure and dynamics in solution. An important bottleneck in NMR protein structure determination is the assignment of NMR peaks to the corresponding nuclei. Structure-based assignment (SBA) aims to solve this problem with the help of a template protein which is homologous to the target and has applications in the study of structure-activity relationship, protein-protein and protein-ligand interactions. We formulate SBA as a linear assignment problem with additional nuclear overhauser effect constraints, which can be solved within nuclear vector replacement's (NVR) framework (Langmead, C., Yan, A., Lilien, R., Wang, L. and Donald, B. (2003) A Polynomial-Time Nuclear Vector Replacement Algorithm for Automated NMR Resonance Assignments. Proc. the 7th Annual Int. Conf. Research in Computational Molecular Biology (RECOMB), Berlin, Germany, April 10-13, pp. 176-187. ACM Press, New York, NY. J. Comp. Bio., (2004), 11, pp. 277-298; Langmead, C. and Donald, B. (2004) An expectation/maximization nuclear vector replacement algorithm for automated NMR resonance assignments. J. Biomol. NMR, 29, 111-138). Our approach uses NVR's scoring function and data types and also gives the option of using CH and NH residual dipolar coupling (RDCs), instead of NH RDCs which NVR requires. We test our technique on NVR's data set as well as on four new proteins. Our results are comparable to NVR's assignment accuracy on NVR's test set, but higher on novel proteins. Our approach allows partial assignments. It is also complete and can return the optimum as well as near-optimum assignments. Furthermore, it allows us to analyze the information content of each data type and is easily extendable to accept new forms of input data, such as additional RDCs.

    Hematology is difficult for students to learn. A beneficial education method for hematology clerkship training is required to help students develop clinical skills. Foreign medical students often encounter communication issues in China. To address this issue, Chinese post-graduates from our institute are willing to assist with educating foreign students. Therefore, we propose a mixed team-based learning method (MTBL) which might overcome communication problems in hematology clerkship. Twenty-two foreign medical Students attended a 2-week hematology clerkship in Fujian Medical University Union Hospital. Twenty-one foreign African medical students were assigned randomly into two groups. Fourteen foreign African medical students were assigned to MTBL group. Each MTBL team included two foreign African medical students and one Chinese post-graduate. Seven foreign African medical students were assigned to lecture-based learning method (LBL) group, which had a foreign medical classmate from Hong Kong or Chinese intern volunteers to serve as translators. The practice test scores of MTBL were significantly higher than LBL group (p problems in hematology clerkship. Foreign medical students and Chinese post-graduates alike can benefit from MTBL. © 2016 by The International Union of Biochemistry and Molecular Biology, 45(2):93-96, 2017.

  12. Regulatory focus and the assignment of punishment

    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/.

    Interprofessional education (IPE) continues to gain traction worldwide. Challenges integrating IPE into health profession programmes include finding convenient times, meeting spaces, and level-appropriate assignments for each profession. This article describes the implementation of a 21-month prospective cohort study pilot programme for the Master of Science in nursing family nurse practitioner (FNP) and doctor of pharmacy (PharmD) students at a private university in the United States. This IPE experience utilised a blended approach for the learning activities; these students had initial and final sessions where they met face-to-face, with asynchronous online activities between these two sessions. The online assignments, discussions, and quizzes during the pilot programme involved topics such as antimicrobial stewardship, hormone replacement therapy, human papilloma virus vaccination, prenatal counselling, emergency contraception, and effects of the Affordable Care Act on practice. The results suggested that the FNP students held more favourable attitudes about online IPE and that the PharmD students reported having a clearer understanding of their own roles and those of the other participating healthcare students. However, the students also reported wanting more face-to-face interaction during their online IPE experience. Implications from this study suggest that effective online IPE can be supported by ensuring educational parity between students regarding the various topics discussed and a consistent approach of the required involvement for all student groups is needed. In addition, given the students desire for more face-to-face interaction, it may be beneficial to offer online IPE activities for a shorter time period. It is anticipated that this study may inform other programmes that are exploring innovative approaches to provide IPE to promote effective collaboration in patient care.

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

    Schuenemann, K. C.

    2012-12-01

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

    The use of eigenspace assignment techniques to synthesize flight control systems for flexible aircraft is explored. Eigenspace assignment techniques are used to achieve a specified desired eigenspace, chosen to yield desirable system impulse residue magnitudes for selected system responses. Two of these are investigated. The first directly determines constant measurement feedback gains that will yield a close-loop system eigenspace close to a desired eigenspace. The second technique selects quadratic weighting matrices in a linear quadratic control synthesis that will asymptotically yield the close-loop achievable eigenspace. Finally, the possibility of using either of these techniques with state estimation is explored. Application of the methods to synthesize integrated flight-control and structural-mode-control laws for a large flexible aircraft is demonstrated and results discussed. Eigenspace selection criteria based on design goals are discussed, and for the study case it would appear that a desirable eigenspace can be obtained. In addition, the importance of state-space selection is noted along with problems with reduced-order measurement feedback. Since the full-state control laws may be implemented with dynamic compensation (state estimation), the use of reduced-order measurement feedback is less desirable. This is especially true since no change in the transient response from the pilot's input results if state estimation is used appropriately. The potential is also noted for high actuator bandwidth requirements if the linear quadratic synthesis approach is utilized. Even with the actuator pole location selected, a problem with unmodeled modes is noted due to high bandwidth. Some suggestions for future research include investigating how to choose an eigenspace that will achieve certain desired dynamics and stability robustness, determining how the choice of measurements effects synthesis results, and exploring how the phase relationships between desired

    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).

  4. Implementation of an agile maintenance mechanic assignment methodology

    Jimenez, Jesus A.; Quintana, Rolando

    2000-10-01

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

    Objective. To evaluate pharmacy students' self-assessment skills with an electronic portfolio program using mentor evaluators. Design. First-year (P1) and second-year (P2) pharmacy students used online portfolios that required self-assessments of specific graded class assignments. Using a rubric, faculty and alumni mentors evaluated students' self-assessments and provided feedback. Assessment. Eighty-four P1 students, 74 P2 students, and 59 mentors participated in the portfolio program during 2010-2011. Both student groups performed well overall, with only a small number of resubmissions required. P1 students showed significant improvements across semesters for 2 of the self-assessment questions; P2 students' scores did not differ significantly. The P1 scores were significantly higher than P2 scores for 3 questions during spring 2011. Mentors and students had similar levels of agreement with the extent to which students put forth their best effort on the self-assessments. Conclusion. An electronic portfolio using mentors based inside and outside the school provided students with many opportunities to practice their self-assessment skills. This system represents a useful method of incorporating self-assessments into the curriculum that allows for feedback to be provided to the students.

    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

    2011-10-01

    In this paper Multi-Objective particle swarm optimization (MOPSO) algorithm is utilized to solve the problem for cooperative multiple target assignment, which is the optimization problem in the discrete search space. At first a model of multi-objective optimization for Cooperative Multiple Target Assignment is established. Aiming to solve out the local convergence phenomenon, the chaos mutation is introduced into PSO for improving global optimal ability. Another underlying problem is that computing speed of the algorithm must meet the operational requirement, so a new kind of Chaos-MOPSO Algorithm is developed to solve the target assignment problem with less population and iterations. At last an authentication example is given in this paper, compared with basic MOPSO and NSGA-II, the Chaos-MOPSO algorithm obtained a better Pareto solution set with smaller computational burden.

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

    Directory of Open Access Journals (Sweden)

    M. Frances Hite

    2009-12-01

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

  4. Evaluating elementary-aged students' abilities to generalize and maintain fluency gains of a performance feedback writing intervention.

    Science.gov (United States)

    Hier, Bridget O; Eckert, Tanya L

    2014-12-01

    National estimates of students' writing abilities in the United States indicate that in 2002, 72% of elementary-aged students were unable to write with grade-level proficiency (Persky, Daane, & Jin, 2003). Although performance feedback is one type of intervention that improves students' writing skills, no study to date has examined the generalization and maintenance of writing fluency improvements developed through these interventions. The primary goal of this study was to determine whether elementary-aged students assigned to a performance feedback intervention condition demonstrated evidence of greater immediate treatment effects, generalization, and maintenance than students assigned to a practice-only condition. Results revealed that in comparison with the practice-only condition (n = 52), students assigned to the performance feedback condition (n = 51) demonstrated significantly greater immediate and generalized writing fluency improvements. However, evidence of maintenance of intervention effects was limited. These findings suggest that, in isolation, performance feedback may produce short-term desired effects on students' writing fluency growth, but that explicit programming of generality may be required to produce long-term achievement gains.

  5. Obesogenic environmental influences on young adults: evidence from college dormitory assignments.

    2014-01-01

    This study utilizes a natural experiment-conditionally random dormitory assignments of first-year US college students-to investigate the influence of obesogenic environmental factors in explaining changes in weight and exercise behavior during the 2009-2010 academic year. The design addresses potential selection biases resulting from the likelihood that individuals sort into built environments that match their preferences for exercise and healthy eating. We find some evidence that the food environment, specifically access to campus dining, significantly affected the weight of female students in our study. Females assigned to dormitories where the nearest campus dining hall was closed on the weekends gained about 1lb less over the course of the year than females assigned to dormitories near dining halls that were open 7 days a week. We also find some evidence that female who lived in close proximity to a grocery store gained less weight over the course of the year. Finally, females who lived closer to campus gym reported more frequent exercise over the course of the year. We do not find significant effects of the built environment on weight changes of males in our sample, but we are cautious to draw strong conclusions from this because the male weight change in our sample was quite small.
