Lotteries in Student Assignment: An Equivalence Result  

Digital Repository Infrastructure Vision for European Research (DRIVER)

This paper formally examines two competing methods of conducting a lottery in assigning students to schools, motivated by the design of the centralized high school student assignment system in New York City. The main result of the paper is that a single and multiple lottery mechanism are equivalent for the problem of allocating students to schools in which students have strict preferences and the schools are indi fferent. In proving this result, a new approach is introduced, th...

Assignment submission, student behaviour and experience  

Directory of Open Access Journals (Sweden)

Full Text Available Time management is one of the life skills students are expected to acquire during their time at university and dealing with workload is an issue for both academics and students. It is suspected that students do not initially manage their time very well and use deadlines to control what they do and when. However, it is also believed that students' time management improves as they progress through their course. This paper explores the student experience of assignment submission with respect to the assessment of one undergraduate module. The aim is to investigate how students deal with their workload, whether their time management improves as they get older and more experienced, if electronic submission has any effect on the way they manage their work and the influence, on submission, of the length of time allowed to complete an exercise. Both quantitative and qualitative data, derived from submission records and the results of interviews and an email survey were used to examine student behaviour and to investigate their experience. The data suggest that while many students find coincident deadlines, often found on university courses, very stressful, they feel that their management of these deadlines improves over time. They value the submission flexibility and economy offered by an electronic system as well as the opportunity, afforded by long deadlines, to discuss assessment strategies and solutions with their peers.

Open Ended Laboratory (OEL Assignment as Tool Imparting Generic Skills for Engineering Students  

Directory of Open Access Journals (Sweden)

Full Text Available Generic skills play a vital role in increasing the employability and marketability of a student. As for the Department of Chemical and Process Engineering, UKM, some of these skills are imparted in the assignment given to students called Open Ended Laboratory (OEL. In this OEL assignment, students are required to propose an experiment title based on the general topic given for that particular semester. The students, working in groups of 3 to 4 students, need to determine the objectives, apparatus and methods as well as execute the experiment. A report including results, discussion, conclusion and references is submitted for evaluation. The final presentation of students’ work is organised in a competition poster presentation format. Skills such as communication (oral and written, organisation, teamwork, innovation and creativity were evaluated for this assignment. We discovered that these skills can be nurtured by looking at the marks given by the judges and peer assessment matrices.

A stepwise multi-assignment spreadsheet model to select student teams  

Directory of Open Access Journals (Sweden)

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

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

Science.gov (United States)

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.

Student Lead Discussions: Articles from the Literature and Final Writing Assignment  

Science.gov (United States)

Assignment #1 Student-led discussion of articles from the literature We assign one or two groups of two or three students to each of four or four or five topics related to climate change, and provide each group a set of related articles from the literature on their assigned topic. The group will lead a one-hour, in-class discussion on the topic, with up to a dozen students and one instructor in each discussion. In preparation for the discussion, the discussion co-leaders must collectively write a set of "Reading Questions" about each assigned article, which help readers focus on the key points made by the articles and can serve as points of discussion. The other students participating in the discussion must read the articles with the aid of these Reading Questions and annotate the portions of the articles that address the Reading Questions. We (instructors) evaluate the Reading Questions written by the co-leaders (they receive a shared grade for these), and we also check the annotated articles turned in by the other discussion participants to ensure that they prepared to participate in the discussion (they receive individual grades this). Discussion co-leaders each receive a grade for the quality of their discussion leadership. The purpose of this assignment is in part to help students prepare for their final writing assignment by requiring that they read a set of articles closely enough to help other students discuss and understand the key points, and get feedback about their level of understanding, up to a month before the final paper on the topic is due. The immediate outcome that we expect from this assignment is a demonstration that students can read the assigned articles critically, identify and articulate the key points, and help engage other students in a discussion about the articles, including conceptually important or difficult aspects of them. Assignment #2: Final writing assignment For this assignment, which follows from the previous one, students are asked to: locate two or more significant additional articles that relate closely to the articles on which they based the discussion that they co-led; and write a 8-12 page (typed, double spaced) overview of the history and current state of our scientific understanding about the topic(s) covered by the set of discussion articles, based on the articles themselves plus relevant material presented in class or in assigned reading. In particular, wherever justified by the source material, students should try to include the following in the narrative: initial observations/evidence; initial hypotheses posed to account for initial observations/evidence (including external forcings and feedbacks); subsequent observations/evidence that have confirmed or disproved earlier hypotheses; technology that made making observations/gathering evidence possible and led to breakthroughs in understanding; scientific controversies and how they played out historically or are currently playing out; current understanding and remaining uncertainties. The outcome should be a written demonstration of the student's ability to analyze and synthesize a set of articles from the literature and supporting materials provided in class to describe the history, current state, and unresolved aspects of our scientific understanding of an interdisciplinary aspect of climate change.

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

Science.gov (United States)

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.

Machine requirements planning and workload assignment using genetic algorithms  

Digital Repository Infrastructure Vision for European Research (DRIVER)

This paper presents a genetic approach to determining the optimal number of machines required in a manufacturing system for meeting a specified production schedule. This use of genetic algorithms is illustrated by solving a typical machine requirements planning problem. Comparison of the respective results obtained by using the proposed approach and a standard mixed-integer programming package shows that the proposed approach is indeed an effective means for optimal manufacturing systems design.

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

Directory of Open Access Journals (Sweden)

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.

Adaptive System for Assigning Reliable Students’ Letter Grades—A Computer Code  

Directory of Open Access Journals (Sweden)

Full Text Available The availability of automated evaluation methodologies that may reliably be used for determining students’ scholastic performance through assigning letter grades are of utmost practical importance to educators, students, and do invariably have pivotal values to all stakeholders of the academic process. In particular, educators use letter grades as quantification metrics to monitor students’ intellectual progress within a framework of clearly specified learning objectives of a course. To students grades may be used as predictive measures and motivating drives for success in a study field. However due to numerous objective and subjective variables that may by be accounted for in a methodological process of assigning students’ grades, and since such a process is often tainted with personal philosophy and human psychology factors, it is essential that educators exercise extra care in maximizing positive account of all objective factors and minimizing negative ramifications of subjectively fuzzy factors. To this end, and in an attempt to make assigning students’ grades more reliable for assessing true-level of mastering specified learning outcomes, this paper will: i provide a literature review on previous works on the most common methods that have traditionally been in use for assigning students’ grades, and a short account of the virtues and/or vices of such methods, and ii present a user-friendly computer code that may be easily adapted for the purpose of assigning students’ grades. This would relieve educators from the overwhelming concerns associated with mechanistic aspects of determining educational metrics, and it would allow them to have more time and focus to obtain reliable assessments of true-level of students’ mastery of learning outcomes by accounting for all possible evaluation components.

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

Science.gov (United States)

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.

Using SOLO taxonomy to explore students’ mental models of the programming variable and the assignment statement  

Directory of Open Access Journals (Sweden)

Full Text Available Introductory programming seems far from being successful at both university and high school levels. Research data already published offer significant knowledge regarding university students’ deficiencies in computer programming and the alternative representations they built about abstract programming constructs. However, secondary education students’ learning and development in computer programming has not been extensively studied. This paper reports on the use of the SOLO taxonomy to explore secondary education students’ representations of the concept of programming variable and the assignment statement. Data was collected in the form of students’ written responses to programming tasks related to short code programs. The responses were mapped to the different levels of the SOLO taxonomy. The results showed that approximately more than one half of the students in the sample tended to manifest prestructural, unistructural and multistructural responses to the research tasks. In addition, the findings provide evidence that students’ thinking and application patterns are prevalently based on mathematical-like mental models about the concepts of programming variable and the assignment statement. The paper concludes with suggestions for instructional design and practice to help students’ building coherent and viable mental models of the programming variable and the assignment statement.

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

Directory of Open Access Journals (Sweden)

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

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

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

Science.gov (United States)

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. PMID:12120115

When teacher-centered instructors are assigned to student-centered classrooms  

Science.gov (United States)

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-centered pedagogy. However, the use of the student-centered classrooms may change instructors' epistemic frameworks over time. Further research should focus on how to better support teachers with shifting epistemic frameworks as well as helping students with lower prior knowledge in student-centered classroom spaces.

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

Directory of Open Access Journals (Sweden)

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

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

Petrographic Problem Solving Assignments  

Science.gov (United States)

Petrographic problem-solving (PPS) assignments consist of a series of two-week mini-projects used within the context of an undergraduate petrology course. The central idea behind PPS assignments is for students to use thin sections as a geologic data source for conducting authentic scientific investigations. For each assignment, students are provided a thin section and corresponding hand sample. Drawing from their initial observations and foundation knowledge, students identify a scientific question, propose a working hypothesis to explain it, test the hypothesis using observations and data collected from the sample, and defend their results in oral presentations and written reports. They use digital cameras interfaced with microscopes to acquire photomicrographs and various software applications to collect and analyze data. For each assignment, students prepare a two-page paper and give a brief presentation to the class (5-10 minutes in duration with 3-5 minutes for discussion). During the presentation sessions, which each require a two-hour class period, class members are encouraged to question their student colleagues. Students are introduced to PPS assignments as part of the take-home final in the prerequisite Microscopy course. Three PPS assignments are in turn engaged in the subsequent Petrology course during the 10-week term. A summative take-home PPS exercise is completed as part of the final exam. In Petrology, PPS assignments augment more traditional laboratory exercises and are specifically aligned with course content, as follows (refer to student handout sheets in supplemental materials section). Using a set of rocks representing distinct lithologies, students are guided to think about what geologic conditions and/or environment the sample formed in. Using a set of plutonic and volcanic rocks from a description and classification exercise, students define their own geologic problem. Using a set of metamorphic rocks, students are instructed to interpret the genetic conditions based on textures and/or mineralogy. Using several different andesite samples, students are directed to consider the origin of the sample in context of a case-study activity conducted during the term. This PPS assignment is completed as part of the final exam and requires a summative two-page paper. In the context of a broad-based undergraduate Earth Science degree program, PPS assignments engage students in the study of Earth materials, actively involve them in the scientific process, and emphasize creative problem solving rather than factual recall.

Student articulation of a nursing philosophical statement: an assignment to enhance critical thinking skills and promote learning.  

Science.gov (United States)

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.

Developing and Evaluating Clinical Written Assignment in Clinical Teaching for the Senior B.S. Nursing Students: An action research  

Directory of Open Access Journals (Sweden)

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.

A system of alias assignment for unidentified patients requiring emergency hospital admission.  

Science.gov (United States)

Many patients are admitted to emergency facilities without positive identification. In the past, these patients were usually assigned a temporary alias name (i.e., John Doe, Jane Doe) which was then changed after positive identification. We have discerned several problems with this procedure and have subsequently developed a coordinated system of alias identification in our hospital. This system allows for: a large pool of distinct alias identities, pre-assignment of hospital numbers to unidentified patients before arrival, and a smooth administrative transition as records are changed from the alias to the true identity.

The relationship between assigned peer mentors and the retention and GPA of female and male engineering students  

Science.gov (United States)

Compared to women's overall enrollment in higher education, the number of women engineering students was low. Additionally, women were less likely than men to retain an engineering major. No one specific reason accounted for the enrollment inequity. Generally, the causes were attributed to an accumulation of barriers women face, as well as the differences between women and men. One retention technique recommended and utilized to retain women engineering students was mentoring. Research confirmed that mentoring provided career and psychosocial benefits for women and men. Claims were made that efforts to retain women students also improved the education for men students. However, few studies examined the relationship between mentoring and the retention and success of women and men engineering students. Further, no study had examined if the benefit of a mentor could be extended to an assigned peer mentor relationship. The objective of this dissertation study was to examine if there was a significant relationship between assigned peer mentors and the retention and GPA of female and male engineering students. This study investigated engineering students at the University of Pittsburgh (Pitt) in Pittsburgh, Pennsylvania. GPA and retention information was gathered for students without a peer mentor and for students with a peer mentor. The results of the analysis showed no difference in retention or GPA for mentored and non-mentored male and female engineering students. Additionally, the study found no significant difference in the SAT scores of the men and women engineering students. There was a significant difference in the GPA of the women and men engineering students, with the women having higher GPA's at the end of the freshman year. Finally, in this study, there was not a significant difference in the retention of women and men engineering students. The data analysis in this study did not support the idea that women at the University of Pittsburgh were more likely to drop out of engineering.

Graduate students' experiences in web site development: a project assignment for nursing informatics class.  

Science.gov (United States)

As healthcare delivery systems' requirements change, nurses will not only have to process and communicate more information, but the nature and types of this information as well as the communication methods will also dramatically change. Nurses must comprehend that information technology is the key to these changes. Korean nurses and nursing students need to enhance their computer technology knowledge and skills as the Korean health delivery system rapidly embraces technological innovations. Yonsei University College of Nursing in Seoul, Korea has the longest history in nursing education and the first graduate nursing programs in Korea. It offered its first nursing informatics (NI) class in 1998, making it one of the first informatics programs in Korean nursing education. The purposes of this project were to develop nursing informatics coursework that enabled students to build skills in developing Web sites, and to measure the effect of the coursework in terms of the students' satisfaction and their confidence level. The author believes that this experience could be a helpful model for an international audience, although this is not an innovative project for some more advanced countries. PMID:12792195

Empirical Selection of Informative Microsatellite Markers within Co-ancestry Pig Populations Is Required for Improving the Individual Assignment Efficiency.  

Science.gov (United States)

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 discernible levels of co-ancestry exist. In the reference group, optimum assignment accuracy was achievable achieved through a combination of different markers by ranking the heterozygosity, FST and allelic number of close lineage populations.

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

Science.gov (United States)

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.

Drafting and acting on feedback supports student learning when writing essay assignments  

Science.gov (United States)

A diverse student population is a relatively recent feature of the higher education system in the United Kingdom. Consequently, it may be thought that more "traditional" types of assessment based around essay writing skills for science undergraduates may be of decreasing value and relevance to contemporary students. This article describes a study in which the process of feedback on, and associated redrafting of, an essay was closely supervised to improve essay writing skills and subsequent exam performance. The results of this study show that students can significantly improve their learning and academic performance, as assessed by final examination mark, by a process that more closely mimics a "real-world" situation of review and redrafting. Additionally, the data show that students benefit from feedback only when this is used appropriately by the student. The article also discusses the continuing importance and relevance of essay writing skills so that writing, and acting upon feedback to do with that writing, remains an integral part of the process of learning.

Sequential reading/writing assignment  

Science.gov (United States)

Right now I use four essay assignments in Paleontology. These assignments work to help students meet several goals of the course, including using reading/writing for critical thinking, synthesizing information from different sources, and formulating new research questions. In particular, the last two of the four assignments are designed as part of a multi-step process. Each student is assigned a particular reading for which he or she will be the primary discussant in a class discussion. Two things are required to make this discussion work and to achieve the (hoped for) "aha" moments for the students. Students must take the time to read and understand the paper they've received. It's useful, particularly if students are just starting out reading primary literature, to discuss how to approach reading a journal article. Maybe most important is inculcating the idea that most people don't read straight through a paper, that multiple readings are important, and that it's not like reading a novel â it takes time to absorb. On discussion day, have students talk about the papers in chronological sequence. There should be back and forth discussion, of course, but when this process works right, (which is most of the time, in my experience), the stepwise introduction and discussion of the papers allows students to see how the problem was originally framed, how it developed, and how new information changes interpretations (and that there may not be a clear resolution). After the discussion, hand out essay assignments tailored to the skills and knowledge you want them to acquire.

Protein-ligand NOE matching: a high-throughput method for binding pose evaluation that does not require protein NMR resonance assignments.  

Science.gov (United States)

Given the three-dimensional (3D) structure of a protein, the binding pose of a ligand can be determined using distance restraints derived from assigned intra-ligand and protein-ligand nuclear Overhauser effects (NOEs). A primary limitation of this approach is the need for resonance assignments of the ligand-bound protein. We have developed an approach that utilizes data from 3D 13C-edited, 13C/15N-filtered HSQC-NOESY spectra for evaluating ligand binding poses without requiring protein NMR resonance assignments. Only the 1H NMR assignments of the bound ligand are essential. Trial ligand binding poses are generated by any suitable method (e.g., computational docking). For each trial binding pose, the 3D 13C-edited, 13C/15N-filtered HSQC-NOESY spectrum is predicted, and the predicted and observed patterns of protein-ligand NOEs are matched and scored using a fast, deterministic bipartite graph matching algorithm. The best scoring (lowest "cost") poses are identified. Our method can incorporate any explicit restraints or protein assignment data that are available, and many extensions of the basic procedure are feasible. Only a single sample is required, and the method can be applied to both slowly and rapidly exchanging ligands. The method was applied to three test cases: one complex involving muscle fatty acid-binding protein (mFABP) and two complexes involving the leukocyte function-associated antigen 1 (LFA-1) I-domain. Without using experimental protein NMR assignments, the method identified the known binding poses with good accuracy. The addition of experimental protein NMR assignments improves the results. Our "NOE matching" approach is expected to be widely applicable; i.e., it does not appear to depend on a fortuitous distribution of binding pocket residues. PMID:16734479

Plagiarism Norms and Practices in Coursework Assignments  

Directory of Open Access Journals (Sweden)

Full Text Available The study compared the plagiarism norms and practices among pre-university, diploma anddegree students. The specific aspects examined were perceived necessity to include citationsin assignments, preferred penalties for plagiarism, and academic writing practices. Thequestionnaire responses of 263 students from three levels of university education wereanalysed. The results showed that the perceived necessity for attribution in assignments is thehighest for the degree students but the norm to require citations and to penalise omission ofcitations is not extensive at all three levels. A majority of the students felt that plagiarismshould be penalised but preferred warning from their lecturer, assignment resubmission andcounselling. Mosaic plagiarism is the most common whereby students combine texts from thesame source or different sources without proper citation and referencing. The most commonunethical help-seeking behaviour is copying another student’s work. The findings suggestthat while lack of knowledge on citation and referencing may lead to improper ornon-attribution of sources, plagiarism cannot be dealt with by instruction on citation andreferencing alone as respect for intellectual property can only be inculcated by treatingplagiarism as a serious academic misdemeanour.

A Framework for Prioritizing Required Knowledge, Skills and Competencies of Cooperative Students  

Directory of Open Access Journals (Sweden)

Full Text Available This research proposed a framework to identify the weight and also the priority of required knowledge, skills and competencies of cooperative students. The academic institute needs to supply the required knowledge, skills and competencies to students before they get in to the host organizations. However, the university has no sufficient resources to supply all requirements to the students. Therefore, a proper method to identify the weight and to identify priorities of considered elements was required. According to a distinctive of analytic hierarchy process, this study applied it to be a part of the framework to deliver the expected outcome.

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

Science.gov (United States)

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. PMID:21675553

Metodología: [...] investigación descriptiva y correlacional que mediante datos interpretados cuantitativa y cualitativamente, relaciona las variables en estudio, para determinar su incidencia en el desarrollo de la autonomía del estudiante. Resultados: aunque algunos estudiantes (25%) son autónomos, el resto no alcanza esa característica, debido al poco control ejercido sobre sus procesos de aprendizaje y a que los trabajos que se les asignan no contribuyen a desarrollar en ellos la autonomía. Conclusiones: las fortalezas encontradas en relación con la motivación de los estudiantes, su satisfacción por el programa y su interés por las nuevas tecnologías de la información y la comunicación son factores que potencializados contribuirían al desarrollo de la autonomía, trabajo que ya se ha iniciado y se comenta al final de este artículo.

Consideration of criteria required for assignment of a (skin) sensitiser a substance of very high concern (SVHC) under the REACH regulation.  

Science.gov (United States)

The identification, characterisation, risk assessment and risk management of materials that cause allergic sensitisation is an important requirement for human health protection. It has been proposed that for some chemical and protein allergens, and in particular for those that cause sensitisation of the respiratory tract (associated with occupational asthma), it may be appropriate to regard them as Substances of Very High Concern (SVHC) under the provisions of REACH (Registration, Evaluation, Authorisation and restriction of CHemicals). We have argued previously that categorisation of sensitising agents as SVHC should be used only in exceptional circumstances. In the present article, the subject of SVHC is addressed from another perspective. Here the information that would be required to provide a compelling case for categorisation of a skin sensitising substance as a SVHC is considered. Three skin sensitising chemicals have been identified to serve as working examples. These are chromate, a potent contact allergen, and the skin sensitisers formaldehyde and isoeugenol. The key criterion influencing the decision regarding a skin sensitiser being categorised as SVHC is the extent to which impacts on the quality of life are reversible. Consequently, SVHC categorisation for skin sensitising chemicals should be used only in exceptional circumstances. PMID:24893346

Research and Teaching: Calibrated Peer Review Assignments in Science Courses--Are They Designed to Promote Critical Thinking and Writing Skills?  

Science.gov (United States)

Calibrated Peer Review (CPR), an online program that purportedly helps students develop as writers and critical thinkers, is being increasingly used by science educators. CPR is an enticing tool since it does not require instructors to grade student writing, and instructors can adopt assignments directly from a library. To determine the extent to which CPR is being used to foster the development of critical thinking and writing skills, the authors analyzed a sample from the CPR assignment library. They found that approximately two-thirds of assignments were designed to engage students in some type of critical thinking, but less than one-third were designed to promote higher-order writing skills. They recommend that the current library be used with caution, a CPR user manual be written (with detailed instructions for creating high-quality writing assignments), and that a new CPR library be created to include only assignments that have been reviewed by experts in critical thinking or writing pedagogy.

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.

Impact of a required fourth-year medical student rotation in physical medicine and rehabilitation.  

Science.gov (United States)

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

Directory of Open Access Journals (Sweden)

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

Required vs. elective research and in-depth scholarship programs in the medical student curriculum.  

Science.gov (United States)

The ability to understand and integrate new knowledge into clinical practice is a necessary quality of good physicians. Student participation in in-depth scholarship could enhance this skill in physicians while also creating a larger cadre of physician-scientists prepared to advance the field of medicine. However, because no definitive data exist demonstrating that in-depth scholarship in medical school leads to improved patient care or to productive academic careers, whether such scholarship should be required as part of the medical school curriculum is unclear. In this article, the authors present both sides of this debate. Theoretical benefits to students of a required scholarly program include closer mentorship by individual faculty, enhanced capabilities in critical interpretation of research findings, and increased confidence to investigate conundrums encountered in clinical care. Society may also benefit by having physicians available to create and apply new knowledge related to biomedicine. These theoretical benefits must be balanced, however, by pragmatic considerations of required scholarly projects including their impact on medical school applications, their effect on the medical curriculum, their costs, the availability of mentors, and their effects on the school's educational culture.

From Animal Farm to Fables â Elements of a Fable Writing Assignment  

Science.gov (United States)

The purpose of this lesson is to provide a culminating assignment after reading the classic novel Animal Farm by George Orwell (1370 Lexile). Shortly after finishing the novel, students will read famous fables and identify how each, including the novel Animal Farm, meet the requirements. Finally, the students will then apply these elements by writing their own fables that include all of the necessary characteristics. This will not only help students build their own creativity, but it will allow application of the lesson and develop writing skills further.

Function-Space Assignment for Educational Facilities?  

Directory of Open Access Journals (Sweden)

Full Text Available Function-space assignment, which allocates a function for each space in a facility, is one of the most important factors in determining the usability performance of a facility. An educational facility is often used through activity participation of different groups such as faculty or construction management graduate students. Members of a group participate in the same activities but with different behaviors (e.g., attendance rate, arrival time. This research uses two modules to optimize the function space assignment. The first module uses simulation technique to randomly generate activity data to accommodate the uncertain nature of activities. The second module uses the fmGA to optimize the function-space assignment. This paper also presents a real case study to demonstrate the use of the proposed model and compares its assignments with those generated by a renovation architect. The result shows a 14.80% higher objective value than the architect's version.

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)

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. PMID:24478680

Inferential backbone assignment for sparse data  

International Nuclear Information System (INIS)

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

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.

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

Energy Technology Data Exchange (ETDEWEB)

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

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

Science.gov (United States)

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.

Utilitarian resource assignment  

CERN Document Server

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

The evolution of a required research program for medical students at the University of Washington School of Medicine.  

Science.gov (United States)

The concepts and tools clinicians use to understand disease and treat patients are the direct product of basic and applied scientific inquiry. To prepare physicians to participate in this tradition of medical science, the University of Washington School of Medicine (UWSOM) created a research requirement in 1981. The objective was to provide students, during their clinical years of medical school, with first-hand experience in hypothesis-driven inquiry and an understanding of the philosophies and methods of science integral to the practice of medicine. A comprehensive curriculum review in 1998-2000 identified several limitations of this requirement. Although many students completed it successfully, others struggled to find mentors, funding, or time as coursework became more demanding. Other students found they had no interest in or aptitude for the research process itself. Accordingly, UWSOM has reaffirmed its commitment to independent inquiry but expanded the ways in which students can meet the requirement. Three research options are now available under the Independent Investigative Inquiry (III) program, generally completed the summer after students' first year of medical school. These are the hypothesis-driven inquiry, a critical review of the literature, or an experience-driven inquiry in community medicine. The goal of UWSOM is to shape new physicians who can manage rapidly changing medical science, information technology, and patient expectations in clinical practice and/or laboratories. The role of III is to teach students to develop personal methods of acquiring new knowledge and integrate it into their professional lives. Faculty support, program oversight, and funding have been increased. PMID:16985345

IS HONORARIUM REQUIRED? REMOVING IRREGULARITIES IN STUDENT CREATIVITY PROGRAM IN INDONESIA

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

Network multiple frame assignment architectures  

Science.gov (United States)

Multiple target tracking methods divide into two broad classes, namely single frame and multiple frame methods. The most successful of the multiple frame methods are multiple hypothesis tracking (MHT) and multiple frame assignments (MFA). In dense tracking environments the performance improvements of multiple frame methods over single frame methods are very significant, making it the preferred solution for many tracking problems. A centralized architecture in which all measurements are sent to one location and processed with tracks being transmitted back to the different platforms is a simple one that is probably optimal in that it is capable of producing the best track quality and a consistent air picture. The centralized tracker is, however, unacceptable for several reasons, notably the communication overloads and single-point-failure. Thus, one must turn to a distributed architecture for both estimation/fusion and data association. One of the simplest network-centric architectures is that of placing a centralized tracker on each platform. The architecture is called Network MFA Centralized, which removes the problem of single-point-failure. Each composite tracker is making its own tracking decisions based on the data it receives, regardless of decisions of other platforms. Therefore, a consistent air picture may not be achieved across the network due to communication delays. The objective of this thesis is the development of two near-optimal Network MFA architectures, namely Network MFA on Local Data and Network Tracks and Network MFA on All data and Network Tracks, that preserve the quality of a centralized tracker across the platforms while managing communication loading and achieving a consistent air picture. One technique that has proved useful for achieving SIAP is to require that each platform be in charge of assigning its own measurements to the network tracks. In the architecture of Network MFA on Local Data, only local data are used in the sliding windows. In the architecture of Network MFA on All Data, remote data as well as local data are used in the sliding window. The results of extensive computations are presented to validate the differences in four tracking architectures.

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

Directory of Open Access Journals (Sweden)

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

Reflective practice: assessment of assignments in English for Specific Purposes  

Directory of Open Access Journals (Sweden)

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

The Art of Probability Assignment  

CERN Document Server

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

An update on NCAA college freshman academic requirements: the impact on students with LD.  

Science.gov (United States)

A recent landmark settlement between the National Collegiate Athletic Association (NCAA) and the U.S. Department of Justice addressed many crucial issues relating to the eligibility of high school students with learning disabilities (LD) and their participation in college freshman athletics. Although the changes agreed upon in the consent decree should have wide-ranging ramifications generally in favor of students with LD, the more subjective nature of these changes opens the door for inevitable inconsistencies, biases, and possible abuses. In addition, larger issues remain unresolved, including (a) the NCAA's denial that is covered by the Americans with Disabilities Act, (b) the inconclusive status of whether college athletics is a major life activity, (c) the NCAA acting as a de facto national school board without rigorous research for setting policy on an informed basis, and (d) the lack of serious initiative on the part of the NCAA to take on a more supportive role in educational reform.

NCAA college freshmen academic requirements: academic standards or unfair roadblocks for students with learning disabilities?  

Science.gov (United States)

The National Collegiate Athletic Association (NCAA) has implemented sweeping legislation for all high school students who desire to participate in Division I or II freshman college athletics. Cutoff scores have been set by the NCAA in two areas: grade-point average (GPA) in "core" high school courses, and college-bound tests. High schools must obtain approval from the NCAA Initial-Eligibility Clearinghouse when determining core courses. Unfortunately, minimal attention has been given in the professional learning disability literature to the implications of the NCAA's policies, especially with regard to federal antidiscrimination legislation. Issues are raised regarding (a) the use of test score cutoffs, (b) a minimum GPA for core courses, (c) the responsibility of high schools, and (d) the lack of alternative eligibility procedures for accessing the essential elements of the NCAA's program. Options for consideration are provided in the context of meeting the needs of students with learning disabilities. PMID:9364896

A probabilistic approach for validating protein NMR chemical shift assignments  

International Nuclear Information System (INIS)

It has been estimated that more than 20% of the proteins in the BMRB are improperly referenced and that about 1% of all chemical shift assignments are mis-assigned. These statistics also reflect the likelihood that any newly assigned protein will have shift assignment or shift referencing errors. The relatively high frequency of these errors continues to be a concern for the biomolecular NMR community. While several programs do exist to detect and/or correct chemical shift mis-referencing or chemical shift mis-assignments, most can only do one, or the other. The one program (SHIFTCOR) that is capable of handling both chemical shift mis-referencing and mis-assignments, requires the 3D structure coordinates of the target protein. Given that chemical shift mis-assignments and chemical shift re-referencing issues should ideally be addressed prior to 3D structure determination, there is a clear need to develop a structure-independent approach. Here, we present a new structure-independent protocol, which is based on using residue-specific and secondary structure-specific chemical shift distributions calculated over small (3-6 residue) fragments to identify mis-assigned resonances. The method is also able to identify and re-reference mis-referenced chemical shift assignments. Comparisons against existing re-referencing or mis-assignment detection programs show that the method is as good or superior to existing approaches. The protocol described here has been implemented intol described here has been implemented into a freely available Java program called 'Probabilistic Approach for protein Nmr Assignment Validation (PANAV)' and as a web server (http://redpoll.pharmacy.ualberta.ca/PANAVhttp://redpoll.pharmacy.ualberta.ca/PANAV) which can be used to validate and/or correct as well as re-reference assigned protein chemical shifts.

Cross-lingual keyword assignment  

CERN Document Server

This paper presents a language-independent approach to controlled vocabulary keyword assignment using the EUROVOC thesaurus. Due to the multilingual nature of EUROVOC, the keywords for a document written in one language can be displayed in all eleven official European Union languages. The mapping of documents written in different languages to the same multilingual thesaurus furthermore allows cross-language document comparison. The assignment of the controlled vocabulary thesaurus descriptors is achieved by applying a statistical method that uses a collection of manually indexed documents to identify, for each thesaurus descriptor, a large number of lemmas that are statistically associated to the descriptor. These associated words are then used during the assignment procedure to identify a ranked list of those EUROVOC terms that are most likely to be good keywords for a given document. The paper also describes the challenges of this task and discusses the achieved results of the fully functional prototype.

A Statistical Programme Assignment Model  

DEFF Research Database (Denmark)

When treatment effects of active labour market programmes are heterogeneous in an observable way  across the population, the allocation of the unemployed into different programmes becomes a particularly  important issue. In this paper, we present a statistical model designed to improve the present assignment  mechanism, which is based on the discretionary choice of case workers. This is done in a duration model context, using the timing-of-events framework to identify causal effects. We compare different assignment  mechanisms, and the results suggest that a significant reduction in the average duration of unemployment spells may result if a statistical programme assignment model is introduced. We discuss several issues regarding the  plementation of such a system, especially the interplay between the statistical model and  case workers.

Fast protein backbone NMR resonance assignment using the BATCH strategy.  

Science.gov (United States)

Probing protein structure, dynamics, and interaction surfaces by NMR requires initial backbone resonance assignment. The protocol for this step has been progressively developed in the last 15 years to provide robust assignments. However, even in the case of favorable conditions (high field magnets and cryogenically cooled probes, small globular proteins, high sample concentration), the assignment step generally takes several days of data collection and analysis, thus precluding studies of unstable proteins and limiting high-throughput applications. Recently, we have introduced the BATCH strategy for fast protein backbone resonance assignment. BATCH benefits from the combination of several tools (BEST/ASCOM/Targeted-Sampling/COBRA/HADAMAC) for time-optimized and highly automated NMR data acquisition, processing, and analysis. In this chapter, we discuss the individual steps of the BATCH method and describe its practical implementation to obtain the backbone resonance assignment of small globular proteins in a few hours of time.

Hybrid Content Delivery: On-Line Lectures and Interactive Lab Assignments  

Science.gov (United States)

A few Purdue University Electrical and Computer Engineering faculty members adopted an experimental format for content delivery in a programming course. In the experimental format, lectures are recorded and delivered on-line. Students attend laboratory sessions and can obtain interactive and individualized assistance; each session teaches one programming tool, including version control, visual programming, creating graphical user interface. Four larger-scale programming assignments require design, implementation, and documentation. We have observed that students sometimes get stuck by simple programming errors (syntax or logic). Most errors are unique by individual students and difficult to generalize in a traditional lecture setting. Some students respond very positively to this approach. An on-line discussion forum is established for interaction. This hybrid format has been experimented in one sophomore and one junior course on hardware design. This paper presents the results when applying this approach to a senior-level software course. We plan to assess the learning experience of the students and compare the results with the two hardware courses many students have taken earlier.

Assignment of Infrared Ammonia Spectra  

Science.gov (United States)

Global ammonia emissions have more than doubled during the period of industrialisation, largely due to widespread use of intensive agricultural techniques and in particular the use of fertilisers and are are set to double again by 2050. However the ammonia data in the present version of HITRAN is not only missing at key wavelengths, but also have significant problems. HITRAN contains 28 057 14NH_3 lines of which some 10 % lack full quantum number assignments. Furthermore 1190 of the assigned lines have demonstrably incorrect assignments (for example are parity forbidden); others have incorrect lower state energies or symmetries leading to incorrect predictions of temperature-dependent spectra. We have undertaken a systematic (re-)analysis of the data in HITRAN. This has been done using both lower state and upper state combination differences starting from a consistent set of lower state energy levels [P. Chen et al, J. Mol. Spectrosc., 236. 116 (2006)] and by using the newly computed variational line list BYTe [S. N. Yurchenko, R. J. Barber , and J. Tennyson, Mon. Not. R. Astron. Soc., in press, (2011)]. Previous errors and misassignments have been corrected and significant progress is being making new assignments. Comparisons with the BYTe line list suggest that HITRAN is also missing a significant number of important transtions, particular at frequencies above 5000 Cm-1.

Heuristic for Task-Worker Assignment with Varying Learning Slopes  

Directory of Open Access Journals (Sweden)

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.

The praxis assignment: experiential learning in a large social-community psychology class.  

Science.gov (United States)

In this article, a faculty member, a graduate student teaching assistant, and four undergraduates describe their experiences with a "Day of Social Justice Praxis Assignment" as a form of experiential learning in a 120-person social-community psychology course. The faculty member lays out the goals of the course and her hopes for the specific assignment. The undergraduates reflect on their experience with the assignment, and the graduate student contextualizes how their work is reflective or not reflective of the work produced in the class and course concepts. The article ends with a critical and frank discussion of the benefits and drawbacks of the assignment. PMID:23480281

Capacity constrained assignment in spatial databases  

DEFF Research Database (Denmark)

Given a point set P of customers (e.g., WiFi receivers) and a point set Q of service providers (e.g., wireless access points), where each q 2 Q has a capacity q.k, the capacity constrained assignment (CCA) is a matching M Q × P such that (i) each point q 2 Q (p 2 P) appears at most k times (at most once) in M, (ii) the size of M is maximized (i.e., it comprises min{|P|, P q2Q q.k} pairs), and (iii) the total assignment cost (i.e., the sum of Euclidean distances within all pairs) is minimized. Thus, the CCA problem is to identify the assignment with the optimal overall quality; intuitively, the quality of q's service to p in a given (q, p) pair is anti-proportional to their distance. Although max-flow algorithms are applicable to this problem, they require the complete distance-based bipartite graph between Q and P. For large spatial datasets, this graph is expensive to compute and it may be too large to fit in main memory. Motivated by this fact, we propose efficient algorithms for optimal assignment that employ novel edge-pruning strategies, based on the spatial properties of the problem. Additionally, we develop approximate (i.e., suboptimal) CCA solutions that provide a trade-off between result accuracy and computation cost, abiding by theoretical quality guarantees. A thorough experimental evaluation demonstrates the efficiency and practicality of the proposed techniques.

Practical Homework Assignments As Part Of Chemistry Teaching And Learning  

Directory of Open Access Journals (Sweden)

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:

The Random Quadratic Assignment Problem  

CERN Document Server

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

Model Refinement Using Eigensystem Assignment  

Science.gov (United States)

IA novel approach for the refinement of finite-element-based analytical models of flexible structures is presented. The proposed approach models the possible refinements in the mass, damping, and stiffness matrices of the finite element model in the form of a constant gain feedback with acceleration, velocity, and displacement measurements, respectively. Once the free elements of the structural matrices have been defined, the problem of model refinement reduces to obtaining position, velocity, and acceleration gain matrices with appropriate sparsity that reassign a desired subset of the eigenvalues of the model, along with partial mode shapes, from their baseline values to those obtained from system identification test data. A sequential procedure is used to assign one conjugate pair of eigenvalues at each step using symmetric output feedback gain matrices, and the eigenvectors are partially assigned, while ensuring that the eigenvalues assigned in the previous steps are not disturbed. The procedure can also impose that gain matrices be dissipative to guarantee the stability of the refined model. A numerical example, involving finite element model refinement for a structural testbed at NASA Langley Research Center (Controls-Structures-Interaction Evolutionary model) is presented to demonstrate the feasibility of the proposed approach.

Selection of a time slot assignment scheme for a fully variable demand assignment SS/TDMA satellite system  

Science.gov (United States)

Fully variable demand assignment in a SS/TDMA satellite system requires dynamic reconfiguration of the onboard switch state sequence. Some advantages can be expected from burst time plan changes where existing bursts on the frame are not splitted but merely shifted in time. The switching mode allocation associated to a specific traffic requirement is obtained from a time slot assignment algorithm, several of which are presently available. This paper reports the compared performances of a SS/TDMA system, in terms of throughput gains and required signalling capacity as obtained from simulation, considering several time slot assignment algorithms. The results show the importance of carefully selecting an appropriate algorithm when the burst management assumes no burst splitting.

Assigning functional meaning to digital circuits  

Energy Technology Data Exchange (ETDEWEB)

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

The study indicates that all ?+c baryons candidates in the 2008 review by the Particle Data Group (PDG) are well described in the mass loaded flux model. The quantum numbers JP of these ?c+ candidates are assigned. If ?c (2765)+ is an orbitally excited ?c+ , it is likely the JP = 3+/2 one. If ?c (2765)+ is an orbitally excited ?c, there ought to be another JP = 3+/2 ?c+ with mass ? 2770 MeV. In the model, there exists no JP = 1+/2 ?c+ (? 2700) predicted in existing literature. ?c(2940)+ is very possible the orbitally excited baryon with JP = 5-/2 (authors)

Motivating Students to Do Homework  

Science.gov (United States)

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

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

Science.gov (United States)

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

Solving multiconstraint assignment problems using learning automata.  

Science.gov (United States)

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

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

International Nuclear Information System (INIS)

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

Comparative assignments of spin of superdeformed bands  

International Nuclear Information System (INIS)

The spin values of the superdeformed (SD) bands in A?190 region have been assigned by comparing the fitting results of Bohr-Mottelson and Harris formulas. The assigned spin values in most of the SD bands are consistent in the both fitting results. For the superdeformed bands whose spin cannot be assigned consistently by the two formulas or the bands whose spin assignment doesn't accord with bandhead moments of inertial systematics, the authors assign their spin using moments of inertial systematics. By using our assigned spin values, the relation of parameters of Bohr-Mottelson formula has been examined. The results show that the relation deduced from three-parameter Harris formula is closer to the experiment than the relation deduced from ab formula. (authors)

A study of engineering student attributes and time to completion of first-year required courses at Texas A&M University  

Science.gov (United States)

For many years, colleges of engineering across the nation have required that a foundational set of courses be completed for entry into upper division coursework or into a specific engineering major. Since 1998, The Dwight Look College of Engineering at Texas A&M University (TAMU) has required that incoming first-time enrolling students complete a Core Body of Knowledge (CBK) with specific cumulative grade points required for specific majors. However, considerations of the time to completion of coursework and other student characteristics and academic factors have not been taken into consideration by TAMU, like most institutions. The purpose of this study is to determine for first year engineering students at TAMU the relationship of gender, ethnicity, engineering major, unmet financial need, cumulative grade point average, and total transfer hours on time to completion of CBK courses. The results of the analysis showed that cumulative grade point average (CGPA) had the strongest relationship to completion of CBK of any independent variable in this study. Statistical significance was found for the following variables in this study: CGPA, gender, ethnicity, and unmet financial need. For the study's variable of major, statistical significance was found for Chemical, Electrical, and Computer Engineering majors. The one variable in this study that did not show statistical significance in relation to time to completion of CBK was transfer credit. Findings with implications for recruitment and retention of underrepresented in engineering is a statistical significance indicating that on average females are taking less time than males to complete CBK. The conclusion from the study is that efforts to attract more women into engineering have merit as do programs to support underrepresented students in order that they may complete CBK at a faster pace. Further study to determine profiles of those majors where statistical significance was found for students taking a greater or lesser amount of time for CBK completion than the mean is recommended, as is ongoing data collection and comparison for current cohorts of engineering majors at TAMU.

Airport Gate Assignment: New Model and Implementation  

CERN Document Server

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.

Efficient Credit Assignment through Evaluation Function Decomposition  

Science.gov (United States)

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

Comparison of syllabi expectations between faculty and students in a baccalaureate nursing program.  

Science.gov (United States)

This study aimed to explore and compare expectations of syllabi between students and faculty in a university baccalaureate nursing department. Knowing what students expect from syllabi can lead to improved student success and may reduce faculty time in clarifying class policies. Faculty and nursing students from eight semesters volunteered to complete a survey exploring syllabi definitions, pertinent content, and the importance of student involvement in syllabi development. The findings suggest there are differences between faculty and student perceptions regarding important syllabi content. Students wanted syllabi that provided the nuts and bolts of how to accomplish each assignment and course requirement most efficiently. Faculty preferred information about student behavior, such as student conduct, participation, and attendance rules. Adult Learning Theory was used to explain these differences. This article points out that faculty may not be as in touch with the needs of adult learners as they claim to be. PMID:19297962

Writing Assignments with a Metacognitive Component Enhance Learning in a Large Introductory Biology Course  

Science.gov (United States)

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.

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

Science.gov (United States)

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

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

Science.gov (United States)

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

Proton resonance assignments of horse ferricytochrome c  

International Nuclear Information System (INIS)

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

Enhancing nursing students' clinical experiences using aesthetics.  

Science.gov (United States)

Traditional nursing education is based strongly in empiric knowledge. However, just as important as empiric knowledge is aesthetic knowledge. Nursing involves multiple ways of knowing, and as such, educational institutions have a responsibility to assist students in gaining knowledge in nontraditonal ways. This article describes an assignment implemented in a pediatric course in a baccalaureate nursing program. Books and movies were used in a an undergraduate nursing course to help students gain insight into illness and disability from the client and family perspective. The students in the course were required to reflect on the meaning of the movie/book and the influence the book/movie had on the student. Based on student responses, this assignment was successful in meeting the objectives originally proposed. The books and movies provided a beginning introduction to, and an appreciation for, client and family experiences. Students were helped to understand illness, abuse, disability, and/or death from the client and/or family perspective. PMID:15682163

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

Science.gov (United States)

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

A Useful Metaheuristic for Dynamic Channel Assignment in Mobile Cellular Systems  

Directory of Open Access Journals (Sweden)

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

Flexible taxonomic assignment of ambiguous sequencing reads  

Directory of Open Access Journals (Sweden)

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.

Computational Assignment of Chemical Shifts for Protein Residues  

CERN Document Server

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

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

Directory of Open Access Journals (Sweden)

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.

Boundary assignment in a recurrent network architecture.  

Science.gov (United States)

We describe a model and simulations of boundary assignment by cortical neurons, a process that assigns edges to figural image regions, as opposed to the background regions on the other side of the edge. The model is composed of several areas, resembling the hierarchical feedforward-feedback organization of areas in the visual cortex. In each successive area along the hierarchy, the visual image is represented at a coarser resolution. Model neurons tend to assign edges to convex image regions. Because of high spatial resolution, information about convexity is not immediately available to all neurons in lower-level areas. In higher-level areas, however, spatial resolution is low, and convexity is coded more reliably. Feedback connections propagate this information to the high-resolution neurons of lower-level visual areas, making it available at all network levels and at all spatial resolutions. The proposed connection scheme assigns edges faster and more reliable to objects than one with only horizontal connections. The model accounts for both psychophysical and neurophysiological data on figural assignment. PMID:17368500

Interprofessional pharmacy observation activity for third-year dental students.  

Science.gov (United States)

Interprofessional learning is a key component of today's health sciences education. Within a two-course series in dental pharmacology and therapeutics, a dental curriculum was revised to provide an interprofessional activity to expose dental students to a community pharmacy setting. The objectives of this activity were to augment students' learning about drug laws and prescription writing, as well as to foster interprofessional relationships and collaboration between pharmacists and dentists. Dental students were scheduled for one-hour observations at community pharmacies on campus. Learning objectives to guide this activity focused on demonstrating community pharmacy operating procedures, identifying ways to minimize prescribing and dosing errors, and understanding how pharmacists can assist dentists in prescribing. Following the observation, students were required to submit a written assignment, which accounted for 14 percent of their course grade. All 119 dental students (100 percent) enrolled in the course for the summers of 2012 and 2013 completed the activity. The average grade on the written assignment was 96.2 out of 100. At the end of the course, students were asked to participate in an online course evaluation survey, for which response rates were 37 percent and 43 percent for 2012 and 2013, respectively. The students rated the pharmacy observation activity favorably on this course evaluation. The pharmacy observation activity provided a successful interprofessional component to the didactic pharmacy course and was well received by the dental students as well as the community pharmacists.

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

Science.gov (United States)

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

An attempt to estimate students' workload.  

Science.gov (United States)

Following the recent introduction of the European Credit Transfer System (ECTS) into several European university programs, a new interest has developed in determining students' workload. ECTS credits are numerical values describing the student workload required to complete course units; ECTS has the potential to facilitate comparison and create transparency between institutional curricula. ECTS credits are frequently listed alongside institutional credits in course outlines and module summaries. Measuring student workload has been difficult; to a large extent, estimates are based only upon anecdotal and casual information. To gather more systematic information, we asked students at the Veterinary Faculty, University of Ljubljana, to estimate the actual total workload they committed to fulfill their coursework obligations for specific subjects in the veterinary degree program by reporting their attendance at defined contact hours and their estimated time for outside study, including the time required for examinations and other activities. Students also reported the final grades they received for these subjects. The results show that certain courses require much more work than others, independent of credit unit assignment. Generally, the courses with more contact hours tend also to demand more independent work; the best predictor of both actual student workload and student success is the amount of contact time in which they participate. The data failed to show any strong connection between students' total workload and grades they received; rather, they showed some evidence that regular presence at contact hours was the most positive influence on grades. Less frequent presence at lectures tended to indicate less time spent on independent study. It was also found that pre-clinical and clinical courses tended to require more work from students than other, more general subjects. While the present study does not provide conclusive evidence, it does indicate the need for further inquiry into the nature of the relationship between teaching and learning in higher education and for evaluation of the benefits (or otherwise) of more "self-directed" study.

Molecular Test to Assign Individuals within the Cacopsylla pruni Complex  

Science.gov (United States)

Crop protection requires the accurate identification of disease vectors, a task that can be made difficult when these vectors encompass cryptic species. Here we developed a rapid molecular diagnostic test to identify individuals of Cacopsyllapruni (Scopoli, 1763) (Hemiptera: Psyllidae), the main vector of the European stone fruit yellows phytoplasma. This psyllid encompasses two highly divergent genetic groups that are morphologically similar and that are characterized by genotyping several microsatellite markers, a costly and time-consuming protocol. With the aim of developing species-specific PCR primers, we sequenced the Internal Transcribed Spacer 2 (ITS2) on a collection of C. pruni samples from France and other European countries. ITS2 sequences showed that the two genetic groups represent two highly divergent clades. This enabled us to develop specific primers for the assignment of individuals to either genetic group in a single PCR, based on ITS2 amplicon size. All previously assigned individuals yielded bands of expected sizes, and the PCR proved efficient on a larger sample of 799 individuals. Because none appeared heterozygous at the ITS2 locus (i.e., none produced two bands), we inferred that the genetic groups of C. pruni, whose distribution is partly sympatric, constitute biological species that have not exchanged genes for an extended period of time. Other psyllid species (Cacopsylla, Psylla, Triozidae and Aphalaridae) failed to yield any amplicon. These primers are therefore unlikely to produce false positives and allow rapid assignment of C. pruni individuals to either cryptic species. PMID:23977301

Study on Optimization of Railway Passenger Train Sets Assignment  

Directory of Open Access Journals (Sweden)

Full Text Available The passenger train sets is the carrier of railway passenger transport production and reasonable use of the passenger train sets is one of the key goals of railway transportation plan. In order to improve the operation efficiency of passenger train sets, optimization model of railway passenger train sets assignment have been built to minimize the non-production staying time of passenger train sets at passenger station based on established train diagram and established configuration of train sets system. On that basis, considering that the parameters of simulated Annealing Algorithm (SA directly affect the efficiency and precision of solving, SA parameters is optimized based on nested partitions, then improved simulated annealing algorithm (ISA is designed to solve this model. Finally, a case study has been carried out taking Zhengzhou railway station of china as an example in order to testify validity of this model and its algorithm by using calculating and comparing analysis and further solved practical problems is analyzed. The results show that the number of passenger train sets required and carriage staying time at passenger station are reduced and this model and its algorithm can be used to optimize railway passenger train sets assignment to improve efficiency of railway passenger train sets assignment.

Backbone resonance assignment and order tensor estimation using residual dipolar couplings  

Energy Technology Data Exchange (ETDEWEB)

An NMR investigation of proteins with known X-ray structures is of interest in a number of endeavors. Performing these studies through nuclear magnetic resonance (NMR) requires the costly step of resonance assignment. The prevalent assignment strategy does not make use of existing structural information and requires uniform isotope labeling. Here we present a rapid and cost-effective method of assigning NMR data to an existing structure-either an X-ray or computationally modeled structure. The presented method, Exhaustively Permuted Assignment of RDCs (EPAR), utilizes unassigned residual dipolar coupling (RDC) data that can easily be obtained by NMR spectroscopy. The algorithm uses only the backbone N-H RDCs from multiple alignment media along with the amino acid type of the RDCs. It is inspired by previous work from Zweckstetter and provides several extensions. We present results on 13 synthetic and experimental datasets from 8 different structures, including two homodimers. Using just two alignment media, EPAR achieves an average assignment accuracy greater than 80%. With three media, the average accuracy is higher than 94%. The algorithm also outputs a prediction of the assignment accuracy, which has a correlation of 0.77 to the true accuracy. This prediction score can be used to establish the needed confidence in assignment accuracy.

Fixed Channel Assignment and Neural Network Algorithm for Channel Assignment Problem in Cellular Radio Networks  

Directory of Open Access Journals (Sweden)

Full Text Available The channel-assignment problem is important in mobile telephone communication. Since the usable range of the frequency spectrum is limited, the optimal channel-assignment problem has become increasingly important. The goal of this problem is to find a channel assignment to requested calls with the minimum number of channels subject to interference constraints between channels. This algorithm consists of: 1 the fixed channel assignment stage; 2 the neural network stage. In the first stage, the calls in a cell determining the lower bound on the total number of channels are assigned channels at regular intervals, then the calls in adjacent six cells are assigned channels by a cluster heuristic method sequentially. In the second stage, the calls in the remaining cells are assigned channels by a binary neural network. The performance is verified through solving well-known benchmark problems. Especially for Sivarajan’s benchmark problems, my algorithm first achieves the lower bound solutions in all of the 12 instances.

State Assignment for Finite State Machine Synthesis  

Directory of Open Access Journals (Sweden)

Full Text Available This paper proposes simulated annealing based algorithm for the synthesis of a finite state machine to determine the optimal state assignment with less area and power dissipation. The algorithm has two annealing stages. In the first rough annealing stage it tries to search in global scope by the proposed rough search method. In the second focusing annealing stage it tries to search in local scope by using proposed focusing search methods intending changing solution slightly. In both stages, the experience of past solution is utilised by combing the best solution in the past and the current solution. The experiments performed on a large suite of benchmarks have established the fact that the proposed method outperforms the published GA-based algorithms. The results have shown the effectiveness of the proposed method in achieving optimal state assignment for finite state machine.

Speeding up sequence specific assignment of IDPs  

Energy Technology Data Exchange (ETDEWEB)

The characterization of intrinsically disordered proteins (IDPs) by NMR spectroscopy is made difficult by the extensive spectral overlaps. To overcome the intrinsic low-resolution of the spectra the introduction of high-dimensionality experiments is essential. We present here a set of high-resolution experiments based on direct {sup 13}C-detection which proved useful in the assignment of {alpha}-synuclein, a paradigmatic IDP. In particular, we describe the implementation of 4D HCBCACON, HCCCON, HCBCANCO, 4/5D HNCACON and HNCANCO and 3/4D HCANCACO experiments, specifically tailored for spin system identification and backbone resonances sequential assignment. The use of non-uniform-sampling in the indirect dimension and of the H-flip approach to achieve longitudinal relaxation enhancement rendered the experiments very practical.

Proton resonance assignments of horse ferrocytochrome c  

International Nuclear Information System (INIS)

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

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

Science.gov (United States)

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

2012 SARA Students Technical Report  

Energy Technology Data Exchange (ETDEWEB)

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

Solving the State Assignment Problem Using Stochastic Search Aided with Simulated Annealing  

Directory of Open Access Journals (Sweden)

Full Text Available Problem statement: Solving the state assignment problem means finding the optimum assignment for each state within a sequential digital circuit. These optimum assignments will result in decreasing the hardware realization cost and increasing the reliability of the digital circuit. Unfortunately, the state assignment problem belongs to the class of nondeterministic polynomial time problems (NP complete which requires heavy computations. Different attempts have been made towards solving the problem with reasonable recourses. Approach: This study presented a methodology for solving the state assignment problem, the methodology conducted a neighborhood search while using a heuristic to determine the fitness of solution. To avoid being trapped at a local optimum solution, a metaheuristic (simulated annealing was utilized for deciding whether a new solution should be accepted. A case study was included to demonstrate the proposed procedure efficiency. Results: The proposed approach finds the optimum assignment for the case study. Conclusion: In this study, we explored the usage of a stochastic search technique inspired by simulated annealing to solve the problem of the state assignment problem. This proved the efficiency of the methodology.

Influence of chemical shift tolerances on NMR structure calculations using ARIA protocols for assigning NOE data  

International Nuclear Information System (INIS)

Large-scale protein structure determination by NMR via automatic assignment of NOESY spectra requires the adjustment of several parameters for optimal performance. Among those are the chemical shift tolerance windows (?), which allow for the compensation of badly matching chemical shifts in the assignment-list and peak-lists, and the maximum number of assignment possibilities allowed per peak (nmax). Here, we test the influence of different values for ? and nmax on the performance of automated assignment of NOESY spectra by ARIA. Using Cesta.py (a Python script available from http://pasteur.fr/binfs/), we analyse the number of rejected peaks and the average number of assignments as a function of ? and derive criteria for optimising ? and nmax prior to structure calculation. The analysis also makes it possible to detect inconsistencies in the dataset, e.g., badly matching frequencies in the NOESY peak-lists and in the provided assignment-list. We show that ARIA can deal with a large number of assignment possibilities for each peak, provided the correct option is present, and that consequently narrow tolerances should be avoided

Evidence-based literacy instruction for individuals who require augmentative and alternative communication: a case study of a student with multiple disabilities.  

Science.gov (United States)

Literacy skills provide numerous benefits to individuals who require augmentative and alternative communication (AAC), including new opportunities for education, work, and social interaction. Literacy skills also have a powerful impact on communication and language development. This paper describes the components of effective evidence-based literacy instruction, including skills to target for instruction, effective instructional procedures to teach these skills, and adaptations to accommodate the needs of individuals with significant speech, motor, and other disabilities. The paper also presents a case study that describes ongoing intervention with an 8-year-old girl with multiple disabilities who required AAC. Evidence-based instruction was provided in phonologic awareness, letter-sound correspondences, decoding, sight-word recognition, reading connected text, reading comprehension skills, and early writing and keyboarding skills. During the 16 months of intervention, a total of 55 hours of instruction, the student acquired 20 letter-sound correspondences, learned to use decoding and sight-word skills to read 60 words, and began to read simple texts both in shared reading activities and independently. She also began to type simple short messages and stories using spelling approximations. The acquisition of these new literacy skills resulted in increased educational opportunities for the learner and also enhanced her language and communication skills. PMID:18645914

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

International Nuclear Information System (INIS)

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

Genetic spectrum assignment model with constraints in cognitive radio networks  

Directory of Open Access Journals (Sweden)

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

Interval Assignment for Volumes with Holes  

Energy Technology Data Exchange (ETDEWEB)

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

A Markov Random Field Framework for Protein Side-Chain Resonance Assignment  

Science.gov (United States)

Nuclear magnetic resonance (NMR) spectroscopy plays a critical role in structural genomics, and serves as a primary tool for determining protein structures, dynamics and interactions in physiologically-relevant solution conditions. The current speed of protein structure determination via NMR is limited by the lengthy time required in resonance assignment, which maps spectral peaks to specific atoms and residues in the primary sequence. Although numerous algorithms have been developed to address the backbone resonance assignment problem [68,2,10,37,14,64,1,31,60], little work has been done to automate side-chain resonance assignment [43, 48, 5]. Most previous attempts in assigning side-chain resonances depend on a set of NMR experiments that record through-bond interactions with side-chain protons for each residue. Unfortunately, these NMR experiments have low sensitivity and limited performance on large proteins, which makes it difficult to obtain enough side-chain resonance assignments. On the other hand, it is essential to obtain almost all of the side-chain resonance assignments as a prerequisite for high-resolution structure determination. To overcome this deficiency, we present a novel side-chain resonance assignment algorithm based on alternative NMR experiments measuring through-space interactions between protons in the protein, which also provide crucial distance restraints and are normally required in high-resolution structure determination. We cast the side-chain resonance assignment problem into a Markov Random Field (MRF) framework, and extend and apply combinatorial protein design algorithms to compute the optimal solution that best interprets the NMR data. Our MRF framework captures the contact map information of the protein derived from NMR spectra, and exploits the structural information available from the backbone conformations determined by orientational restraints and a set of discretized side-chain conformations (i.e., rotamers). A Hausdorff-based computation is employed in the scoring function to evaluate the probability of side-chain resonance assignments to generate the observed NMR spectra. The complexity of the assignment problem is first reduced by using a dead-end elimination (DEE) algorithm, which prunes side-chain resonance assignments that are provably not part of the optimal solution. Then an A* search algorithm is used to find a set of optimal side-chain resonance assignments that best fit the NMR data. We have tested our algorithm on NMR data for five proteins, including the FF Domain 2 of human transcription elongation factor CA150 (FF2), the B1 domain of Protein G (GB1), human ubiquitin, the ubiquitin-binding zinc finger domain of the human Y-family DNA polymerase Eta (pol ? UBZ), and the human Set2-Rpb1 interacting domain (hSRI). Our algorithm assigns resonances for more than 90% of the protons in the proteins, and achieves about 80% correct side-chain resonance assignments. The final structures computed using distance restraints resulting from the set of assigned side-chain resonances have backbone RMSD 0.5 - 1.4 Å and all-heavy-atom RMSD 1.0 - 2.2 Å from the reference structures that were determined by X-ray crystallography or traditional NMR approaches. These results demonstrate that our algorithm can be successfully applied to automate side-chain resonance assignment and high-quality protein structure determination. Since our algorithm does not require any specific NMR experiments for measuring the through-bond interactions with side-chain protons, it can save a significant amount of both experimental cost and spectrometer time, and hence accelerate the NMR structure determination process.

SUITABILITY OF AIOU TELEVISION AND ITS IMPACT ON STUDENTS’ ACHIEVEMENTS  

Directory of Open Access Journals (Sweden)

Full Text Available ABSTRACT The requirement of television for educational purposes arises when specific educational objectives are not achieved through traditional way of teaching. There are a number of things television can do better than the average teacher and traditional educational institutions, but situations where both teacher and educational institutions are not available, television is the answer to obtain educational objectives, Lochte, (1993. This research paper investigates relationship between TV broadcast time, day and duration and student achievement. Data was collected from 197 from urban and rural, male and female students of the Allama Iqbal Open University, enrolled in the spring 2006 Semester in the selected courses. No strong relationship was found between Learning from TV and academic achievement in the AIOU situation. Use of television in the AIOU Situation will be more effective if transmission day, time and duration are adjusted according to the students’ demand and when studentsassignments are based on both textbook and TV programs.

Spin assignments of superdeformed bands in europium  

International Nuclear Information System (INIS)

A comprehensive investigation of the superdeformed bands observed in 142,143,144,147Eu was given. The fluctuation in the transition energies has been removed. The smoothed transition energies were fitted by the ab-expression or its modification. The spins of these bands, except for band 4 of 147Eu, have been assigned conclusively. The exit spin in 143Eu was proposed to be 29/2, different from that asserted to be determined experimentally but remains to be confirmed. The corresponding values in 142Eu and 144Eu(a) are 21 and 28, lower than those proposed in the literature by 6 and 8 units, respectively. Two pairs of superdeformed bands in 147Eu, i.e. bands 1,5 and bands 2,3 were proposed to be signature partners. The exit spins are 53/2 and 63/2 for the former pair, and 43/2 and 41/2 for the latter pair. In addition, both of them have a rather large de-coupling constant (?-1), implying they are of K = 1/2 and built on the single particle level ?[651]? or ?[530]?. This assignment may be helpful for the studies of the so-called identical bands and pseudo spin problem. The signature partner pairs observed in 144,148Eu are not included in the investigation

LOGIC BASED RULES FOR PROJECT ASSIGN PREDICTION  

Directory of Open Access Journals (Sweden)

Full Text Available Project assigning is a major decision for any software organization like IT companies to their developer employees. The uncertain domain of assessment has been in need of a reliable and consistent system to help simplify the decision making process. Logic rules provides a completely different, unorthodox way to approach a control problem. This method focuses on what the system should do rather than trying to understand how it works. One can concentrate on solving the problem rather than trying to model the system mathematically,if that is even possible. This almost invariably leads to quicker, cheaper solutions. This research work will help in analysis assign project to a developer according to different factors like reliability,his hardware interaction, programming level,configuration etc the decision factor helps in making decision above how to select accurate developer for the project. Using the algorithm has been defined, new rules defined,according to different rules added and take average decision based on data collected by different categories of the employees.

Dynamic assignment: there is an equilibrium !  

CERN Document Server

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.

y not part of the optimal solution. Then an A* search algorithm is employed to find a set of optimal side-chain resonance assignments that best fit the NMR data. These side-chain resonance assignments are then used to resolve the NOE assignment ambiguity and compute high-resolution protein structures. Tests on five proteins show that Nasca assigns resonances for more than 90% of side-chain protons, and achieves about 80% correct assignments. The final structures computed using the NOE distance restraints assigned by Nasca have backbone RMSD 0.8–1.5 Å from the reference structures determined by traditional NMR approaches.

Electre tri method used to storage location assignment into categories  

Scientific Electronic Library Online (English)

Full Text Available SciELO Brazil | Language: English Abstract in english 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.

Assignment of uncertainties to scientific data  

International Nuclear Information System (INIS)

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

Designing Cancer-Killing Artificial Viruses to Improve Student Understanding of Microbiology  

Directory of Open Access Journals (Sweden)

Full Text Available Our objective was to assess the effectiveness of a “learning by designing” group project used in a lower-division Microbiology course. Students used knowledge gained from the course to design an artificial virus that would kill cancer cells. The assignment required groups to integrate the individual course topics into a unified, complex understanding of the field of microbiology. Throughout the course, students and the instructor collaborated in creating a rubric to evaluate the groups’ final presentations. This paper reports the results of an assessment of the project by comparing the instructor’s and the students’ scores for the presentations. Students’ and the instructor’s scores were correlated; the Pearson coefficient of 0.52 was statistically significant. The results indicate that students gained sufficient knowledge to accurately evaluate proposed designs. Additionally, the overall course grade distribution improved compared to the semester before the project was introduced. Finally, in order to engage students in thinking about their own learning process, they completed a reflection assignment that required them to discuss the changes in their understanding of microbiology over the course of the semester. Our assessment indicates that a design project can serve as an effective and useful learning technique in undergraduate Microbiology courses, though modifications are suggested.?

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

Directory of Open Access Journals (Sweden)

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

Joint Power Control, Base Station Assignment, and Channel Assignment in Cognitive Femtocell Networks  

Directory of Open Access Journals (Sweden)

Full Text Available Cognitive radio and femtocells are recent technology breakthroughs that aim to achieve throughput improvement by means of spectrum management and interference mitigation, respectively. However, these technologies are limited by the former's susceptibility to interference and the latter's dependence on bandwidth availability. In this paper, we overcome these limitations by integrating cognitive radio and femtocell technology and exploring its feasibility and throughput improvement. To realize this, we propose an integrated architecture and formulate a multiobjective optimization problem with mixed integer variables for the joint power control, base station assignment, and channel assignment scheme. In order to find a pareto optimal solution, a weighted sum approach was used. Based on numerical results, the optimization framework is found to be both stable and converging. Simulation studies further show that the proposed architecture and optimization framework improve the aggregate throughput as the client population rises, hence confirming the successful and beneficial integration of these technologies.

Regulatory focus and the assignment of punishment  

Directory of Open Access Journals (Sweden)

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.

Undergraduate students’ information search practices  

Directory of Open Access Journals (Sweden)

Full Text Available This paper investigates undergraduate students’ information search practices.The subjects were 250 undergraduate students from two university departments in Greece, and a questionnaire was used to document their search practices. The results showed that the Web was the primary information system searched in order to findinformation for university assignments, while the level of database searching was verylow. In particular, the search engine Google was used very frequently either foruniversity assignments or for personal purposes. Regarding students’ practices inevaluating Web?based information, the top criteria reported were ‘relevance ofinformation’ and ‘easy to understand’. Students’ self?efficacy concerning Web?searchingwas found to be high and positively related to the variables ‘frequency of Web use’ and‘years of internet use’. Implications for students’ training are discussed. Students’ search behaviour needs to be expanded beyond the Web search engines, to include a wider range of information retrieval systems.

Wavelength assignment for locally twisted cube communication pattern on optical bus network-on-chip  

Science.gov (United States)

Optical network-on-chip (NoC) is a new designing of Multi-Processor System-on-Chip (MPSoC). Global bus is the simplest logical topology of optical NoC. Static routing and wavelength assignment is one important communication mechanism of optical NoC. This paper addresses the routing and wavelength assignment (RWA) problem for locally twisted cube communication pattern on global bus optical NoC. For that purpose, a routing scheme, that is an embedding scheme, is proposed, and a wavelength assignment scheme under the embedding scheme is designed. The number of required wavelengths is shown to attain the minimum, guaranteeing the optimality of the proposed scheme.

Lightpath routing and wavelength assignment in WDM networks  

Science.gov (United States)

This paper consider the design of lightpath Routing and Wavelength Assignment (RWA) problem in Wavelength Division Multiplexing (WDM) networks with or without wavelength conversion. To minimize the required network cost, one has to device as few network devices and take the least network building cost with respect to the required demand requirements. In our model, the required cost including the one to install wavelengths in the network nodes and the building cost to use a specific wavelength in a specified optical link. The problem is formulated as a binary linear programming where the objective function is the minimization of network building cost. Many literatures have pointed out that solving the formulation of this kind is very computationally demanding and heuristic algorithms and/or relaxation techniques are needed for problems with nontrivial size. In this paper, a Lagrangian relaxation based solving procedure is developed for the RWA problem. In particular, We first transfer the RWA problem into a multicommodity integer flow problem using graph transformation technique by adding some artificial network nodes and links with proper cost on them. To achieve minimum network cost, two problem solving phases are developed for networks with and without wavelength converter respectively. In the first phase, we try to optimize the cost of routing without violating the wavelength continuity constraints. If no feasible solutions are obtained in this phase, it means there are no sufficient paths to route lightpaths without wavelength converter. We then take another graph extension with wavelength converter geared to the RWA problem and then applying a shortest path based heuristic algorithm to solve the problem based on the solution obtained from first phase. Two network topologies, GTE network and NSFNET network, are used to evaluate the computational results. Examining the Lagrangian based heuristic results and the lower bounds reveal that the proposed algorithm can efficiently provide a nearly optimal solution for our problem.

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

International Nuclear Information System (INIS)

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

Establishing relevance as a way to motivate introductory students  

Science.gov (United States)

Introduction to Geology students are asked to write a two page (5-6 paragraph) editorial that addresses what geology is and why it is important to society. To gather the information for their editorial, students have to interview at least five individuals (two of whom have to be professionals or faculty members), and consult the mission statements and goals of professional geology organizations (i.e. AAPG, AGU, GSA, SEPM, etc.) Students then synthesize their research and construct a well-written editorial with appropriate citations that will either explain, persuade, criticize, or praise. In completing the assignment, students not only better understand why it is good to study geology, but also have an appreciation for the scope and content of an Intro to Geology course. Teaching Tips Adaptations that allow this activity to be successful in an online environment I have not used this activity in an online environment, although students in my face-to-face class submit their assignment online through learning management software (i.e. BlackBoard, Desire2Learn, etc.). Elements of this activity that are most effective This is effective because it requires that students become active in the learning process, and although the writing is minimal, they have to really pay attention to their wording, point of view, and purpose. Moreover, when students interview professionals, other faculty, their parents, or friends, they are often engaged in interesting conversations that provide important insights. I have found that this helps motivate students and excites them about the content of the course. Recommendations for other faculty adapting this activity to their own course: I recommend that other faculty use the content of the editorials periodically by referring back to student responses throughout the duration of their courses. It helps draw students back into the course, and helps connect them to why they are studying geology in the first place. In years when written work are less than satisfactory, I often require students to swap editorials and provide peer critiques. This usually helps students who struggle with their writing.

Nursing practice problems in private hospitals in Jordan: students' perspectives.  

Science.gov (United States)

This paper grew from an exploration of clinical practice problems in a private hospital in Jordan. Senior nursing students in a governmental university studied these issues while focusing on leadership and management issues. The private sector is of a secondary focus in nursing research. In Jordan, nursing studies that explore the nursing profession and its related issues have been limited in the literature. A student assignment in the "Nursing Leadership and Management" course required the students to work in groups to identify a nursing practice problem, and its contributing causes and suggested solutions. The nursing shortage; job dissatisfaction; burnout; and turnover were the identified nursing practice problems. Causes and solutions of these problems were explored. PMID:17689428

Developing a Research Tool to Gauge Student Metacognition  

Science.gov (United States)

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

The Assignment of Scores Procedure for Ordinal Categorical Data  

Science.gov (United States)

Ordinal data are the most frequently encountered type of data in the social sciences. Many statistical methods can be used to process such data. One common method is to assign scores to the data, convert them into interval data, and further perform statistical analysis. There are several authors who have recently developed assigning score methods to assign scores to ordered categorical data. This paper proposes an approach that defines an assigning score system for an ordinal categorical variable based on underlying continuous latent distribution with interpretation by using three case study examples. The results show that the proposed score system is well for skewed ordinal categorical data.

Integration of an Intelligent Tutoring System with a Web-based Authoring System to Develop Online Homework Assignments with Formative Feedback  

Science.gov (United States)

A web-based authoring tool, developed using VaNTH CAPE technology, is used to construct innovative online assignments that provide students with real time formative feedback as they attempt to solve quantitative engineering problems. The interactive system has found favor with instructors, teaching assistants and students. Because each step taken by the student in the problem solution is recorded by the accompanying learning management system, students and instructors can easily review modules to determine where the student went wrong. This approach also frees Teaching Assistants from the necessity of grading homework, most of which are worked correctly, and allows them to spend time with the students who most need their help. Because of the many options available in the authoring tool, novice developers often find it relatively difficult to design, construct and debug adaptive learning modules. The purpose of this work is to develop an Intelligent Tutoring System (ITS) that can be integrated with the authoring tool to provide personal guidance to new users as they develop homework problems. Previous ITSs have proved useful to learners in a wide variety of different domains, such as algebra, chemistry, and physics, resulting in gains of over one standard deviation. Clearsighted, Inc. has teamed with VaNTH to develop a version of the web authoring tool that allows information to flow between the ITS and the authoring tool. What is most interesting regarding this work is that the CAPE-based authoring tool was developed and works as its own stand-alone web-based application. Using Clearsighted, Inc.s tools, an ITS was constructed that required no modification to the original authoring tool. The resulting ITS provides immediate feedback in a tutorial setting, offering help when requested and adaptive just-in-time messages, as well as noting incorrect actions. All of this feedback, from the users point of view, seemingly comes from the authoring tool. A series of tutorials have been developed that will provide guidance to new users as they develop online homework assignments. Evaluation of the system is done by comparing authoring tasks performed by groups who learned to author without using the integrated system to groups performing the same tasks with the ITS.

Preparing students for class: How to get 80% of students reading the textbook before class  

Science.gov (United States)

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

CAMRA: Chemical shift based computer aided protein NMR assignments  

International Nuclear Information System (INIS)

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

Development of reference assignment in children: a direct comparison to the performance of cognitive shift  

Directory of Open Access Journals (Sweden)

Full Text Available The referent of a deictic embedded in a particular utterance or sentence is often ambiguous. Reference assignment is a pragmatic process that enables the disambiguation of such a referent. Previous studies have demonstrated that receivers use social-pragmatic information during referent assignment; however, it is still unclear which aspects of cognitive development affect the development of referential processing in children. The present study directly assessed the relationship between performance on a reference assignment task (Murakami & Hashiya, 2014 and the Dimensional Change Card Sort (DCCS task in three- and five-year-old children. The results indicated that the performance of the 3-year-olds in an event that required an explicit (cognitive shift was associated with DCCS performance; however, this was not observed in the 5-year-olds, possibly due to a ceiling effect. Thus, while the development of skills that mediate cognitive shifting might adequately explain the explicit shift of attention in conversation, the pragmatic processing underlying the implicit shift, which requires reference assignment, might follow a different developmental course.

Designing a Written Assignment To Promote the Use of Critical Thinking Skills in an Introductory Chemistry Course  

Science.gov (United States)

This article describes the creation, use, and application of a rubric to a written assignment in order to promote the critical thinking skills of students in an introductory chemistry course. Inquiry-guided instruction was the primary strategy used in the classroom to introduce freshmen to the application of critical thinking skills. The rubric targeted particular cognitive skills. The intellectual standards that define critical thinking are embedded in the rubric. The delineation of a specific rubric provided students with clear goals, allowing them to identify a deficiency without providing the specificity that could potentially hamper the students' critical thinking process. Teachers may use this rubric to foster critical thinking skills over a semester-long assignment.

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 homologou...

Earth station interface for demand assignment applications  

Science.gov (United States)

The ESI interface with a message processor for Bolt Beranek and Newman called the PSAT. M/A COM LINKABIT does not have a PSAT, but design verification testing must be performed in order to ensure the enhancements performed under this contract meet the requirements set forth in the proposal. In addition, each of the six ESI's produced will require the performance of an Acceptance Test Procedure prior to shipment. M/A-COM LINKABIT has proposed the design and construction of a PSAT Emulator which could exercise the ESI in a manner which approximates the PSAT well enough to verify operational status. The PSAT Emulator is designed around a Hewlett Packard 9836 desktop computer, whose principal means of communication with the ESI will be through an Emulator Interface Circuit Card Assembly (CCA). The design of the Emulator CCA is a substantial task and is now underway. This Technical Report discusses the design requirements for that CCA and will, we hope, impart some overall understanding of the PSAT Emulator. It should also be noted that BB&N is producing a new message processor, the BSAT, which streamlines message handling protocols for improved channel throughput.

Patient-oriented performance measures of diagnostic tests. 2. Assignment potential and assignment strength.  

Science.gov (United States)

Assignment Potential (AP) is a performance measure of a diagnostic test, characterizing the chance that, as a consequence of performing the test, the probability of disease will exceed a decision threshold, thereby permitting a management action to be taken. Another performance measure, Assignment Strength (AS) characterizes the average extent to which a decision threshold will be exceeded when the post-test probability of disease does exceed the threshold. Both AP and AS are functions of prior probability of disease and decision threshold, and can be represented as two-dimensional contour maps indicating their behavior throughout the entire probability and threshold space. AP and AS can be determined for both discrete-valued tests and tests with continuous spectra of results. The contour map displays facilitate determination of the values of these measures at any prior probability and threshold, as well as visual sensitivity analysis for ranges of prior probability and/or threshold. AP and AS may be useful to the clinician in prospective evaluation of a diagnostic test in situations where formal decision analysis is not feasible. PMID:6727585

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

Science.gov (United States)

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

Fully automated sequence-specific resonance assignments of hetero- nuclear protein spectra  

International Nuclear Information System (INIS)

Full automation of the analysis of spectra is a prerequisite for high-throughput NMR studies in structural or functional genomics. Sequence-specific assignments often form the major bottleneck. Here, we present a procedure that yields nearly complete backbone and side chain resonance assignments starting from a set of heteronuclear three-dimensional spectra. Neither manual intervention, e.g., to correct lists obtained from peak picking before feeding these to an assignment program, nor protein-specific information, e.g., structures of homologous proteins, were required. By combining two earlier published procedures, AUTOPSY [Koradi et al. (1998) J. Magn. Reson., 135, 288-297] and GARANT [Bartels et al. (1996) J. Biomol. NMR, 7, 207-213], with a new program, PICS, all necessary steps from spectra analyses to sequence-specific assignments were performed fully automatically. Characteristic features of the present approach are a flexible design allowing as input almost any combination of NMR spectra, applicability to side chains, robustness with respect to parameter choices (such as noise levels) and reproducibility. In this study, automated resonance assignments were obtained for the 14 kD blue copper protein azurin from P. aeruginosa using five spectra: HNCACB, HNHA, HCCH-TOCSY, 15N-NOESY-HSQC and 13C-NOESY-HSQC. Peaks from these three-dimensional spectra were filtered and calibrated with the help of two two-dimensional spectra: 15N-HSQC and 13C-HSQC. The rate of incorrect assignments is less than 1.5% for backbone nuclei and about 3.5% when side chain protons are also considered

RDC derived protein backbone resonance assignment using fragment assembly  

International Nuclear Information System (INIS)

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

IMPROVISED CHANNEL ASSIGNMENT TECHNIQUE FOR WIRELESS NETWORK USING GENETIC ALGORITHM  

Directory of Open Access Journals (Sweden)

Full Text Available Wireless technology development is basically because of transformation of what has been largely a medium for supporting voice telephony into a medium for supporting other services, such as the transmission of video, images, text, and data. Thus, the demand for new wireless capacity is growing at a very rapid pace. Although there are, of course, still a great many technical problems to be solved in wireline communications. The traditional resources that have been used to add capacity to wireless systems are radio bandwidth and transmitter power. Unfortunately, these two resources are among the most severely limited in the deployment of modern wireless networks: radio bandwidth because of the very tight situation with regard to useful radio spectrum, and transmitter power because mobile and other portable services require the use of battery power, which is limited. These two resources are simply not growing or improving at rates that can support anticipated demands for wireless capacity. For efficient utilization of the radio spectrum, a frequency reuse scheme that is consistent with the objectives of increasing capacity and minimizing interference is required. Allocation of channels to a cellular system is important from a performance point of view. The allocation of a set of channels to each base station during the planning process i.e. Frequency Planning Process is a NP-complete optimization problem with constraints for which different approached have been proposed. Examples: Various attempts via graph coloring algorithms, neural networks, set theory and other methods via simulated annealing algorithms have been proposed to solve this problem. However, this paper is to solve the channel assignment problem in wireless network using a Genetic Algorithm. The general purpose Simple Genetic Algorithm has been proved to cope up with varied channel demands in different wireless networks.

Threat evaluation and weapon assignment decision support: A review of the state of the art  

Directory of Open Access Journals (Sweden)

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

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

Directory of Open Access Journals (Sweden)

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