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

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

    Directory of Open Access Journals (Sweden)

    Bilge Gokhan Celik

    2013-06-01

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

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

    Science.gov (United States)

    Harbor, Jon

    2014-05-01

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

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

    Directory of Open Access Journals (Sweden)

    Ali Jabbar Al BAKAA

    2014-11-01

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

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

    Science.gov (United States)

    Sturdivant Allen, Anita Kay

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

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

    Science.gov (United States)

    Serder, Margareta; Jakobsson, Anders

    2015-09-01

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

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

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

    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.

    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.

    2007-12-01

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

Quiz the students on one or two of the topics. Encourage the students to design or develop some creative real-world examples based on a chapter discussed or a topic of interest. Require that students originate, develop, support and defend a viewpoint using a specifically assigned material. Make the students practice using or utilizing a set of new technical terms they have encountered in an assigned chapter. Have students develop original examples explaining the different terms. Ask the students to select one important terminology from the previous classroom discussions. Encourage the students to explain why they selected that particular word. Ask them to talk about the importance of the terminology from the point of view of their educational objectives and future career. Angelo, T. A. (1991).

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

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

    Science.gov (United States)

    Werth, Arman Karl

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

    2015-01-01

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

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

  1. Online supervision at the university : A comparative study of supervision on student assignment face-to-face and online

    2015-01-01

    The article presents and condenses the background, findings and results of a one yearlong research project on online supervision and feedback at the university. The article builds on presentations and discussions in different research environments and conferences on higher education research and development (Bengtsen & Jensen 2013a; Bengtsen & Jensen 2013b; Jensen & Bengtsen 2014). Through an empirical study of supervision and feedback on student assignments at the university across face-to-face and online settings we show firstly, that the traditional dichotomy between face-to- face and online supervision proves unhelpful when trying to understand how online supervision and feedback is a pedagogical phenomenon in its own right, and irreducible to the face-to-face context. Secondly we show that not enough attention has been given to the way different digital tools and platforms influence the supervisory dialogue in the specific supervision context. We conclude by terming this challenge in online supervision aform of ‘torn pedagogy’; that online tools and platforms destabilise and ‘tear’ traditional understandings of supervision pedagogy ‘apart’. Also, we conclude that on the backdrop of a torn pedagogy we forge a new concept of “format supervision” that enables supervisors to understand and reflect their supervision practice, not as caught in the physical-virtual divide, but as a choice between face-to-face and online formats that each conditions the supervisory dialogue in their own particular ways and with their own pedagogical implications.

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

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

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

    Varghese, Joe; Jacob, Molly

    2015-01-01

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

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

    Science.gov (United States)

    Bitner, Betty L.

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

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

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

    2015-11-01

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

Abstract in english The issue of "types of texts assigned to university students" has been the object of several research projects; however, few of them focus on the graduate level. This particular project carried out an inquiry into the points of view of Master's and PhD students from diverse disciplines, through a su [...] rvey in which 118 students participated. Results show differences depending on whether the programs belong to the schools of arts, humanities, and social sciences; engineering and information technology; or natural sciences and mathematics. With the exception of abstracts, the texts usually required of the students are different form those they will write upon completion of their studies. Articles for scientific journals (the main type of text used in all disciplines) are rarely assigned. A study such as this one may foster future research on graduate programs and their connection to the professional or academic field.

  9. Personnel dose assignment practices

    International Nuclear Information System (INIS)

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

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

    Science.gov (United States)

    Fisanick, Laura M.

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

    A collaboration of medical professionals with economists and computer scientists involved in "market design" had led to the redesign of the clearinghouse assigning medical students to internships in Israel. The new mechanism presents significant efficiency gains relative to the previous one, and almost all students get a better chance of getting what they want. Continued monitoring of the new mechanism is required to verify that it is not abused, and explore whether it can be improved. Other organizations in Israel may also be able to profit from the experience that accumulates from market design, both in Israel and abroad. PMID:25821580

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

    Science.gov (United States)

    Bryan, T; Nelson, C

    1994-10-01

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

    2015-07-01

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

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

    International Nuclear Information System (INIS)

    Full text: Introduction: Training of X-ray technicians in Bulgaria takes place in the Medical Colleges to Medical Universities. It's purpose is providing professional training of students in the area of diagnostic imaging, nuclear medicine and radiotherapy. Practical training is based on the scientific and theoretical knowledge and skills and is organized in pedagogic environment, adequate to regularities for a gradual formation of practical skills and habits. The practical training and pre-graduation internship are performed in 1895 from total of 3810 hours, which represents about fifty percent of all training of X-ray technicians. Students are in groups of 2-4 students. Practical training is organized, accomplished and monitored by the teacher training practice with the help of a mentor in the clinical base. Purpose: To present the tasks of practical training of students - X-ray technicians and the requirements for the personal characteristics and activity of mentors. Materials and methods: Documentary method has been used. Literature and normative documents related to the practical training of students in 'X-ray technician' of Medical Colleges have been studied. The job descriptions of senior clinical X-ray technicians have been examined carefully. Results: By analyzing literature sources, we have structured the tasks of practical training and pre-graduation internship of students - X-ray technicians, also we have described the requirements for personal qualities of mentors and systematize the activities they perform. Conclusion: Practical training plays an important role in adaptation of young X-ray technicians to the conditions of medical work, improving their skills and habits, and to the development of specific practical skills for being able to respond to emergency conditions and to solve complicated practical situations. The mentor is the supervisor and the controller of interns who helps this happen through his own example, qualities and attitudes towards the profession and students

    Full Text Available In this paper, an integrated simulation optimization model for the assignment problems is developed. An effective algorithm is developed to evaluate and analyze the back-end stored simulation results. This paper proposes simulation tool SIMASI (Simulation of assignment models to simulate assignment models. SIMASI is a tool which simulates and computes the results of different assignment models. This tool is programmed in DOT.NET and is based on analytical approach to guide optimization strategy. Objective of this paper is to provide a user friendly simulation tool which gives optimized assignment model results. Simulation is carried out by providing the required values of matrix for resource and destination requirements and result is stored in the database for further comparison and study. Result is obtained in terms of the performance measurements of classical models of assignment system. This simulation tool is interfaced with an optimization procedure based on classical models of assignment system. The simulation results are obtained and analyzed rigorously with the help of numerical examples. 

  2. 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

    2014-01-01

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

    2002-01-01

    In the paper we consider the invariant zero assignment problem in a linear multivariable system with several inputs/outputs by constructing a system output matrix. The problem is reduced to the pole assignment problem by a state feedback (modal control) in a descriptor system or a regular one. It is shown that the zero assignment and pole assignment are mathematically equivalent problems.

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

    International Nuclear Information System (INIS)

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

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.

  2. Assignment of OVSF Codes in Wideband CDMA

    Science.gov (United States)

    Askari, Mehdi; Saadat, Reza; Nakhkash, Mansour

    In Wideband Code Division Multiple Access, Channelization codes are used to preserve the orthogonality between physical channels, in order to increasing system capacity. The Orthogonal Variable Spreading Factor (OVSF) codes are used as the channelization codes in this system. In WCDMA, it is possible to provide multi-rate service by employing the OVSF codes, which can be generated in the form of tree structure. This scheme is known as OVSF-CDMA. One important limitation of OVSF-CDMA is that the system must maintain the orthogonality among the assigned codes. The maintenance of the orthogonality among the assigned OVSF codes causes the code blocking problem. Efficient channelization code management, result in high efficiency of code utilization and increasing system capacity. This research compares the performance of OVSF code assignment schemes, in terms of code blocking probability and number of required code reassignment.

    2009-04-01

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

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

  18. The Art of Probability Assignment

    CERN Document Server

    Dimitrov, Vesselin I

    2012-01-01

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

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

    Directory of Open Access Journals (Sweden)

    Wipawee Tharmmaphornphilas

    2010-04-01

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

  1. Student Blogging about Physics

    Daniels, Karen E.

    2010-09-01

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

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:

  5. Using Content Reading Assignments in a Psychology Course to Teach Critical Reading Skills

    OpenAIRE

    2013-01-01

    Liberal arts students are expected to graduate college with fully developed critical reading and writing skills. However, for a variety of reasons these skills are not always as well developed as they might be - both during and upon completion of college. This paper describes a reading assignment that was designed to increase students’ discipline-specific critical reading and writing skills. The assignment was piloted in a mid-level social psychology class. Pre-test/post-test comparisons indi...

    International Nuclear Information System (INIS)

    We pose and solve a problem concerning consistent assignment of quantum probabilities to a set of bases associated with maximal projective measurements. We show that our solution is optimal. We also consider some consequences of the main theorem in this paper in conjunction with Gleason’s theorem. Some potential applications to state tomography and probabilistic quantum secret-sharing scheme are discussed. (paper)

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

    Science.gov (United States)

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

    2010-05-01

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

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

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

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

    Hendricson, William D; Kleffner, John H

    2002-01-01

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

    2010-01-01

    Interprofessional education (IPE) is increasingly called upon to improve health care systems and patient safety. Our institution is engaged in a campus-wide IPE initiative. As a component of this initiative, a required online interprofessional patient-safety-focused course for a large group (300) of first-year medical, dental, and nursing students was developed and implemented. We describe our efforts with developing the course, including the use of constructivist and adult learning theories and IPE competencies to structure students' learning in a meaningful fashion. The course was conducted online to address obstacles of academic calendars and provide flexibility for faculty participation. Students worked in small groups online with a faculty facilitator. Thematic modules were created with associated objectives, online learning materials, and assignments. Students posted completed assignments online and responded to group members' assignments for purposes of group discussion. Students worked in interprofessional groups on a project requiring them to complete a root cause analysis and develop recommendations based on a fictional sentinel event case. Through project work, students applied concepts learned in the course related to improving patient safety and demonstrated interprofessional collaboration skills. Projects were presented during a final in-class session. Student course evaluation results suggest that learning objectives and content goals were achieved. Faculty course evaluation results indicate that the course was perceived to be a worthwhile learning experience for students. We offer the following recommendations to others interested in developing an in-depth interprofessional learning experience for a large group of learners: 1) consider a hybrid format (inclusion of some face-to-face sessions), 2) address IPE and broader curricular needs, 3) create interactive opportunities for shared learning and working together, 4) provide support to faculty facilitators, and 5) recognize your learners' educational level. The course has expanded to include students from additional programs for the current academic year. PMID:23745069

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

  19. The Random Quadratic Assignment Problem

    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 ...

  20. Assigned shares in compensation for radiation-related cancers

    International Nuclear Information System (INIS)

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

  1. Assigned value improves memory of proper names.

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

    2013-01-01

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

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

    2015-04-01

    Given the psychological and financial costs involved with failing a clinical course, especially in developing countries, an alternative educational method was tested with students who had to repeat the year-long endodontic course at the University of Chile Faculty of Dentistry. The objectives of the intervention were to deepen theoretical knowledge and practical experiences, as well as to reinforce personal confidence in an endodontic clinical setting for students who failed the regular endodontic course. The aim of this study was to evaluate the success of this new model of educational intervention. In the study, 28 students who had failed the endodontic course repeated it with an alternative teaching method. The students attended patients immediately following practical competence exams, and they had access to simulated models that used rotary instruments and access cavities and had emergency care practice. Feedback sessions were held after each clinical session. Final grades were compared with those of other students who repeated the course without the intervention from 2007 to 2009. A survey was administered to understand the causes of initial failure and their opinions of the intervention. Students who participated in the alternative course did significantly better than their counterparts from previous years who did not receive the intervention (5.7±0.3 vs. 5.4±0.2; ppersonal insecurity and slow clinical care performance (54.2% of the students). The intervention course not only improved grades but also generated interest in endodontics, a contrasting perspective to the frustration students usually express after repeating the course. The results of this study support the introduction of similar interventions in endodontics and perhaps other courses. PMID:25838011

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

    Science.gov (United States)

    Hwang, Jin-Ok; Min, Sung-Gi

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

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

    Science.gov (United States)

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

    2011-12-01

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

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

    Science.gov (United States)

    Schuenemann, K. C.

    2012-12-01

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

  2. Integrated assignment and path planning

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

    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.

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

    Directory of Open Access Journals (Sweden)

    M. Frances Hite

    2009-12-01

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

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

    2015-08-01

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

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

    Science.gov (United States)

    Sojka, S. L.

    2014-12-01

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

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

    Directory of Open Access Journals (Sweden)

    Kleanthis C. THRAMBOULIDIS

    2003-04-01

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

  8. Computational Assignment of Chemical Shifts for Protein Residues

    CERN Document Server

    Bratholm, Lars A

    2013-01-01

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

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

    International Nuclear Information System (INIS)

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

    1997-01-01

    This paper analyzes how case assignment takes place in double object constructions in English. It has been claimed in the literature that case could be either structural or inherent. I will provide some evidence showing that this distinction is problematic under certain circumstances. In this sense, I will suggest three different possibilities to unify these two processes of case assignment. In the first place, I will consider unification through PP-movement, which seems to ...

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

    Directory of Open Access Journals (Sweden)

    de Brevern Alexandre G

    2005-09-01

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

  2. Flexible taxonomic assignment of ambiguous sequencing reads

    Directory of Open Access Journals (Sweden)

    2011-01-01

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

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

    Science.gov (United States)

    van Voorhis, Frances Landis

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

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

    Wireless sensor networks benefit from communication protocols that reduce power requirements by avoiding frame collision. Time Division Media Access methods schedule transmission in slots to avoid collision, however these methods often lack scalability when implemented in \\emph{ad hoc} networks subject to node failures and dynamic topology. This paper reports a distributed algorithm for TDMA slot assignment that is self-stabilizing to transient faults and dynamic topology change. The expected local convergence time is O(1) for any size network satisfying a constant bound on the size of a node neighborhood.

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

    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.

  17. 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

    2014-12-01

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

  2. Heuristics to solve the integrated airline crew assignment problem

    Scientific Electronic Library Online (English)

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

    2015-01-01

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

    Sopina, Liza Elizaveta; McNeill, Rob

    2015-01-01

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

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

    Science.gov (United States)

    Pascarella, Andrea M.

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

    2011-06-01

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

    2015-06-01

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

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

    2011-01-01

    One of the main computational challenges facing metagenomic analysis is the taxonomic identification of short DNA fragments. The combination of sequence alignment methods with taxonomic assignment based on consensus can provide an accurate estimate of the microbial diversity in a sample. In this note, we show how recent improvements to these consensus methods, as implemented in the latest release of the TANGO tool, can provide an improved estimate of diversity in simulated datasets.

    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 tryin...

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

    2013-01-01

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

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

    2004-01-01

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

    2009-11-01

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

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

    Directory of Open Access Journals (Sweden)

    Yun-Chi Chen

    2013-08-01

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

  1. On the problem of resonance assignments in solid state NMR of uniformly 15N, 13C-labeled proteins

    Science.gov (United States)

    Tycko, Robert

    2015-04-01

    Determination of accurate resonance assignments from multidimensional chemical shift correlation spectra is one of the major problems in biomolecular solid state NMR, particularly for relative large proteins with less-than-ideal NMR linewidths. This article investigates the difficulty of resonance assignment, using a computational Monte Carlo/simulated annealing (MCSA) algorithm to search for assignments from artificial three-dimensional spectra that are constructed from the reported isotropic 15N and 13C chemical shifts of two proteins whose structures have been determined by solution NMR methods. The results demonstrate how assignment simulations can provide new insights into factors that affect the assignment process, which can then help guide the design of experimental strategies. Specifically, simulations are performed for the catalytic domain of SrtC (147 residues, primarily ?-sheet secondary structure) and the N-terminal domain of MLKL (166 residues, primarily ?-helical secondary structure). Assuming unambiguous residue-type assignments and four ideal three-dimensional data sets (NCACX, NCOCX, CONCA, and CANCA), uncertainties in chemical shifts must be less than 0.4 ppm for assignments for SrtC to be unique, and less than 0.2 ppm for MLKL. Eliminating CANCA data has no significant effect, but additionally eliminating CONCA data leads to more stringent requirements for chemical shift precision. Introducing moderate ambiguities in residue-type assignments does not have a significant effect.

    2011-12-01

    The Student Airborne Research Program (SARP) of the National Aeronautics and Space Administration (NASA) and the National Suborbital Education and Research Center (NSERC) is a unique six week multidisciplinary paid training program which directly integrates students into the forefront of airborne remote sensing science. Students were briefly trained with one week of lectures and laboratory exercises and then immediately incorporated into ongoing research projects which benefit from access to the DC-8 airborne platform and the MODIS-ASTER Airborne Simulator (MASTER) sensor. Students were split into three major topical categories of Land, Ocean, and Air for the data collection and project portions of the program. This poster details the techniques and structure used for the student integration into ongoing research, professional development, hypothesis building and results as developed by the professor and mentor of the Land focus group. Upon assignment to the Land group, students were issued official research field protocols and split into four field specialty groups with additional specialty reading assignments. In the field each group spent more time in their respective specialty, but also participated in all field techniques through pairings with UC Davis research team members using midday rotations. After the field campaign, each specialty group then gave summary presentations on the techniques, preliminary results, and significance to overall group objectives of their specialty. Then students were required to submit project proposals within the bounds of Land airborne remote sensing science and encouraging, but not requiring the use of the field campaign data. These proposals are then reviewed by the professor and mentor and students are met with one by one to discuss the skills of each student and objectives of the proposed research project. The students then work under the supervision of the mentor and benefit again from professor feedback in a formal practice presentation session. At the end of the six week program, students present to all SARP program focus groups, mentors, professors, and, in addition, NSERC and NASA airborne science and education program directors and personnel.

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

    2009-01-01

    Full Text Available Problem statement: The purpose of this study was to determine undergraduate student perceptions in the areas of group experience within the context of an undergraduate organizational behavior business class community service assignment. College students, as part of an in-class service-learning project, were assigned to teach business related curriculum to at-risk high school students. Approach: Students, enrolled in the required senior level business course, were then assessed in the following areas: service learning experience and group experience. A multiple-choice questionnaire was administered to undergraduate students in an organizational and administrative behavior class and analyzed for correlations and relationships. The survey was administered in week eleven of a traditional semester and in the last week of the community service project. The survey was comprised of seven questions relating to group experience and one based on the impact of the community service project itself. Results: Significant findings revealed a positive correlation between the group experience and the feelings toward the project. In addition, multiple linear regressions suggested a positive and significant prediction. Conclusion: From the findings, implications for the development of experiential learning projects for use in the college classroom will be discussed. When paired with the results of previous research, the findings of this research can be very useful in developing group based service learning projects at the undergraduate level. Based upon the importance of service learning as an experiential teaching style, it is critical to understand how to better use this vehicle for discovery.

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

    Scientific Electronic Library Online (English)

    Marcele Elisa, Fontana; Cristiano Alexandre Virgínio, Cavalcante.

    2013-08-01

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

  6. Interval Assignment for Volumes with Holes

    Energy Technology Data Exchange (ETDEWEB)

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

    1999-09-07

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

    Recently, the National Research Council's framework for next generation science standards highlighted "computational thinking" as one of its "fundamental practices". Students taking a physics course that employed the Arizona State University's Modeling Instruction curriculum were taught to construct computational models of physical systems. Student computational thinking was assessed using a proctored programming assignment, written essay, and a series of think-aloud interviews, where the students produced and discussed a computational model of a baseball in motion via a high-level programming environment (VPython). Roughly a third of the students in the study were successful in completing the programming assignment. Student success on this assessment was tied to how students synthesized their knowledge of physics and computation. On the essay and interview assessments, students displayed unique views of the relationship between force and motion; those who spoke of this relationship in causal (rather than obs...

    Full Text Available In higher educational institutions, ethics is the very core of the people that institutions are trying to morally shape. In a few years’ time, these students will be assigned to some work place where they will be forced to make decisions which can affect businesses and more importantly – human lives. In that respect, what seems like a simple doubt about right or wrong, becomes alarmingly significant and in times where economics and profit drive the thinking of the society, ethics are often overlooked. Universities attempt to instil ethical principles by providing courses on the topic, and through demonstrated behaviour of professors. This article presents introduction of a new class, devoted to ethics, as an application of stated approaches. The article shows some details of the class, with emphasis put onto the behaviour and decision that students showed during conducting given assignments. Findings have been divided into technical and ethical aspects.

  11. Approximate algorithms for partitioning and assignment problems

    Science.gov (United States)

    Iqbal, M. A.

    1986-01-01

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

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

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

    International Nuclear Information System (INIS)

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

    2013-04-01

    Undergraduate physics students commonly collaborate with one another on homework assignments, especially in more challenging courses. However, there currently exists a dearth of empirical research directly comparing the structure of students' collaborative networks to their academic performances in lower and upper division physics courses. We investigate such networks and associated performances through a mandated collaboration reporting system in two sophomore level and three junior level physics courses during the Fall 2012 and Spring 2013 semesters. We employ social network analysis to quantify the structure and time evolution of networks involving approximately 140 students. Analysis includes analytical and numerical assignments in addition to homework and exam scores. Preliminary results are discussed.

    Full Text Available Abstract Background Estimation of pharmacokinetic parameters after intermittent intravenous infusion (III of antibiotics, such as aminoglycosides or vancomycin, has traditionally been a difficult subject for students in clinical pharmacology or pharmacokinetic courses. Additionally, samples taken at different intervals during repeated dose therapy require manipulation of sampling times before accurate calculation of the patient-specific pharmacokinetic parameters. The main goal of this study was to evaluate the effectiveness of active learning tools and practice opportunities on the ability of students to estimate pharmacokinetic parameters from the plasma samples obtained at different intervals following intermittent intravenous infusion. Methods An extensive reading note, with examples, and a problem case, based on a patient’s chart data, were created and made available to students before the class session. Students were required to work through the case before attending the class. The class session was devoted to the discussion of the case requiring active participation of the students using a random participation program. After the class, students were given additional opportunities to practice the calculations, using online modules developed by the instructor, before submitting an online assignment. Results The performance of students significantly (P?P? Conclusions Despite being a difficult subject, students achieve mastery of pharmacokinetic calculations for the topic of intermittent intravenous infusion when appropriate active learning strategies and practice opportunities are employed.

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

  3. 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.

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

  5. Cluster Chain Based Relay Nodes Assignment

    2014-01-01

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

    2009-09-01

    Full Text Available Pair programming is a lightweight software development technique in which two programmers work together at one computer. In literature, many benefits of pair programming have been proposed, such as increased productivity, improved code quality, enhanced job satisfaction and confidence. Although pair programming provides clear pedagogical benefits, its collocation requirement and the limited time during a lab session are serious barriers in the full deployment and evaluation of this programming technique. This paper reports on a study that investigated the effectiveness of Virtual Pair Programming (VPP on student performance and satisfaction in an introductory Java course where students worked collaboratively in pairs on homework programming assignments, using online tools that integrated desktop sharing and real time communication. The results of this study support previous research findings and suggest that VPP is an effective pedagogical tool for flexible collaboration and an acceptable alternative to individual/solo programming experience, regarding productivity, code quality, academic performance and student satisfaction.

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

    Science.gov (United States)

    Wetzel, L. R.

    2011-12-01

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

The students who are identified as under-performing received, on average, lower grades than their fellow students but spent more time completing the homework assignments. These students are great candidates for targeted advertisement of student resources such as tutoring services. The students who are identified in the over-performing student population received higher grades than their fellow students, but spent less time completing the homework assignments. These students are great candidates for honors programs, independent research projects, and peer-tutoring programs. Incorporating these evaluation criteria to online homework systems will allow instructors to quickly identify students in these academic student populations.

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

    The recruitment, selection and retention of nursing students have become crucial in securing the future workforce required by the NHS. Concerns regarding the academic performance of what is a changing student profile led to an audit being performed to explore the predictive relationship between entry qualifications, age, gender, attendance and academic performance in a cohort of pre-registration Diploma of Nursing students. Data was collated from a cohort of 154 students. Statistical analysis demonstrated that students with higher level entry qualifications performed consistently better than those with lower level qualifications. Mature students, over the age of 26, achieved better average marks in coursework and examinations that their younger peers. Year 1 performance predicted year 3 performance in both examinations and assignments. Non-attendance was shown to have an impact on academic performance with a correlation existing between high absenteeism and poor academic achievement. The findings highlight interesting issues for nurse educators relating to academic student support particularly in first year; recruitment and selection of the most suitable candidates; absenteeism monitoring and curriculum design.

  14. Symmetric Logic Synthesis with Phase Assignment

    Benschop, N F

    2001-01-01

    Decomposition of any Boolean Function BF_n of n binary inputs into an optimal inverter coupled network of Symmetric Boolean functions SF_k (k \\leq n) is described. Each SF component is implemented by Threshold Logic Cells, forming a complete and compact T-Cell Library. Optimal phase assignment of input polarities maximizes local symmetries. The "rank spectrum" is a new BF_n description independent of input ordering, obtained by mapping its minterms onto an othogonal n \\times n grid of (transistor-) switched conductive paths, minimizing crossings in the silicon plane. Using this ortho-grid structure for the layout of SF_k cells, without mapping to T-cells, yields better area efficiency, exploiting the maximal logic path sharing in SF's. Results obtained with an optimization tool "Ortolog" based on these concepts, for very fast O(n^2) detecting and enhancing local symmetries of a BF_n, are reported. Relaxing symmetric- to planar- Boolean functions is sketched, to improve low- symmetry BF decomposition.

    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.

    2007-12-01

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

    2010-12-01

    Misconceptions can adversely affect students’ mastery of the fundamental geoscience concepts necessary for development of the knowledge base required to become a professional geoscientist. In the fall of 2009, in-class learning assessments were introduced into a large (400 student) undergraduate introductory geoscience course to help students develop expert-like problem solving skills for geologic problems. They were also designed to reveal students’ misconceptions on geoscience concepts in order to help direct the course of instruction. These assessments were based on simple, real-world scenarios that geoscientists encounter in their research. One of these assessments focused on the application of concepts of geologic time. It asked students to give the relative ages of granite, schist and shale based on a sketch of two outcrops, and to describe the reasoning behind their answer. In order to test all of the principles of relative age, the assignment had two possible solutions. A post-course analysis of student responses on these assessments was carried out using a modified constant comparative analysis method to identify common misconceptions. This analysis revealed that 61% of students failed to identify both possible solutions. Furthermore, 55% of students applied the principle of superposition to intrusive igneous and metamorphic rocks, and 18% treated the once connected outcrops as having separate geologic histories. 56% of students could not support their proposed geologic history with appropriate reasoning. These results suggest that the principles of relative geologic time that students had the greatest difficulty with were when to apply the principle of superposition and how to apply the principle of original continuity. Students also had difficulty using the principles of relative age to provide appropriate scientific reasoning for their choices.

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

  3. Comparing the performance and preference of students experiencing a Reading Aloud Accommodation to those who do not on a virtual science assessment

    Science.gov (United States)

    Shelton, Angela

    Many United States secondary students perform poorly on standardized summative science assessments. Situated Assessments using Virtual Environments (SAVE) Science is an innovative assessment project that seeks to capture students' science knowledge and understanding by contextualizing problems in a game-based virtual environment called Scientopolis. Within Scientopolis, students use an "avatar" to interact with non-player characters (NPCs), artifacts, embedded clues and "sci-tools" in order to help solve the problems of the townspeople. In an attempt to increase students' success on assessments, SAVE science places students in an environment where they can use their inquiry skills to solve problems instead of reading long passages which attempt to contextualize questions but ultimately cause construct-irrelevant variance. However, within these assessments reading is still required to access the test questions and character interactions. This dissertation explores how students' in-world performances differ when exposed to a Reading Aloud Accommodation (RAA) treatment in comparison to a control group. Student perceptions of the treatment are also evaluated. While a RAA is typically available for students with learning disabilities or English language learners, within this study, all students were randomly assigned to either the treatment or control, regardless of any demographic factors or learning barriers. The theories of Universal design for learning and brain-based learning advocate for multiple ways for students to engage, comprehend, and illustrate their content knowledge. Further, through providing more ways for students to interact with content, all students should benefit, not just those with learning disabilities. Students in the experimental group listened to the NPCs speak the dialogue that provides them with the problem, clues, and assessment questions, instead of relying on reading skills to gather the information. Overall, students in the treatment group statistically outperformed those in the control. Student perceptions of using the reading aloud accommodation were generally positive. Ideas for future research are presented to investigate the accommodation further.

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

    2014-01-01

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

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

  13. A study of the effects of gender and different instructional media (computer-assisted instruction tutorials vs. textbook) on student attitudes and achievement in a team-taught integrated science class

    Science.gov (United States)

    Eardley, Julie Anne

    The purpose of this study was to determine the effect of different instructional media (computer assisted instruction (CAI) tutorial vs. traditional textbook) on student attitudes toward science and computers and achievement scores in a team-taught integrated science course, ENS 1001, "The Whole Earth Course," which was offered at Florida Institute of Technology during the Fall 2000 term. The effect of gender on student attitudes toward science and computers and achievement scores was also investigated. This study employed a randomized pretest-posttest control group experimental research design with a sample of 30 students (12 males and 18 females). Students had registered for weekly lab sessions that accompanied the course and had been randomly assigned to the treatment or control group. The treatment group used a CAI tutorial for completing homework assignments and the control group used the required textbook for completing homework assignments. The Attitude toward Science and Computers Questionnaire and Achievement Test were the two instruments administered during this study to measure students' attitudes and achievement score changes. A multivariate analysis of covariance (MANCOVA), using hierarchical multiple regression/correlation (MRC), was employed to determine: (1) treatment versus control group attitude and achievement differences; and (2) male versus female attitude and achievement differences. The differences between the treatment group's and control group's homework averages were determined by t test analyses. The overall MANCOVA model was found to be significant at p homework averages showed no significant differences. Contradictory to the findings of this study, anecdotal information from personal communication, course evaluations, and homework assignments indicated favorable attitudes and higher achievement scores for a majority of the students in the treatment group.

    2013-01-01

    Full Text Available Academic procrastination is fairly and commonly found among college students. The lack of understanding in making the best use of computer technology may lead to anxiety in terms of operating computer hence cause postponement in completing course assignments related to computer operation. On the other hand, failure in achieving certain academic targets as expected by parents and/or the students themselves also makes students less focused and leads to tendency of postponing many completions of course assignments. The aim of this research is to investigate contribution of anxiety in operating computer and academic stress toward procrastination on students. As much as 65 students majoring in psychology became participants in this study. The results showed that anxiety in operating computer and academic stress play significant role in influencing academic procrastination among social sciences students. In terms of academic procrastination tendencies, anxiety in operating computer and academic stress, male students have higher percentage than female students.

Como primer objetivo se planteó recoger información respecto de la visión de los docentes acerca de las competencias sociales esperadas y efectivamente observadas en sus alumnos. Tomando como referencia al Programa TE COMPETE (Universidad de Cantabria – España y Proyecto Tuning América Latina, se encuestaron cuarenta docentes. Del análisis de las encuestas se pudo observar que las competencias esperadas en los estudiantes son numéricamente muy inferiores a las observadas en ellos, siendo más notoria la diferencia en las competencias participativas ypersonales. La falta de habilidades de comunicación y de liderazgo fueremarcada por los docentes, quienes, a su vez, consideraron como muyimportantes a las competencias personales e interpersonales para eldesarrollo del futuro Medico Veterinario. Se concluye que resultaríaconveniente iniciar un camino de cambio que apunte a fomentar yfortalecer las competencias sociales de alumnos de Medicina Veterinaria. Para promover este cambio será necesario que el profesor cuente con espacios que le permitan la adquisición de estrategias metodológicas que faciliten su actuación didáctica.SummaryIn the Faculty of Veterinary Science (Universidad Nacional del Litoral – Argentina is being developed an investigation related to Social Competences already acquired and those expected in future Veterinarians. The aim of the study is to describe social skills that are already acquired by students at the beginning of their course of studies, propitiated by scholar and family environment, and social skills that are desirable to develop in students for a proper university insertion, and subsequently, in the working sphere. Firstly, it was gathered information regarding the teacher’s visionabout social competence, expected and actually observed in their students. Having taken as a reference the program called “TE COMPETE” (Cantabria University – Spain and the Latin America Tuning Proyect, forty teachers were surveyed. From the analysis of the surveys, it was observed that the competences expected in students were fewer than those seen in them, specially the participative and personal competences. The lack of communication skills and leadership was highlighted by teachers, who, in turn, considered as very important personal and interpersonal skills to develop in the future Medical Veterinary. We conclude that it would be convenient to initiate a way of change in order to encourage and strengthen social competences in Veterinary students. To promote this change it will be necessary that teachers have a place that allow the acquisition of methodological strategies to facilitate their teaching performance.

    Kennes, John; Monte, Daniel

    2014-01-01

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

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

    Directory of Open Access Journals (Sweden)

    Dwayne E. Paré

    2009-10-01

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

  19. Helping Students Test Programs That Have Graphical User Interfaces

    Directory of Open Access Journals (Sweden)

    2008-08-01

    Full Text Available Within computer science education, many educators are incorporating software testing activities into regular programming assignments. Tools like JUnit and its relatives make software testing tasks much easier, bringing them into the realm of even introductory students. At the same time, many introductory programming courses are now including graphical interfaces as part of student assignments to improve student interest and engagement. Unfortunately, writing software tests for programs that have significant graphical user interfaces is beyond the skills of typical students (and many educators. This paper presents initial work at combining educationally oriented and open-source tools to create an infrastructure for writing tests for Java programs that have graphical user interfaces. Critically, these tools are intended to be appropriate for introductory (CS1/CS2 student use, and to dovetail with current teaching approaches that incorporate software testing in programming assignments. We also include in our findings our proposed approach to evaluating our techniques.

    2013-04-01

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

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

    Directory of Open Access Journals (Sweden)

    DP Lötter

    2013-06-01

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

The primary motivation was to circumvent the issues that often appear to the instructors implementing peer review activities with pre-assigned groups, without posing additional workload to the instructor or diminishing the learning outcomes. In the study, 36 sophomore students in a Computer Networking course were randomly assigned into two conditions: 20 in Assigned-Pair, where the students worked in pre-defined dyad, and 17 in Free-Selection, where students were able to explore and select peer work for review. Result analysis showed a very strong tendency in favor of the Free-Selection students regarding both domain specific (conceptual) and domain-general (reviewing) knowledge.

    2013-05-01

    Full Text Available The cultural dimension of Uncertainty Avoidance is analysed in this study of an introduction to blended learning for international students. Content analysis was conducted on the survey narratives collected from three cohorts of management undergraduates in the United Arab Emirates. Interpretation of certainty with blended learning was found in: student skills with technology; student acknowledgement of course organisation; and student appreciation of online feedback. Uncertainty with the introduction of blended learning was found: when membership was assigned for group work, higher quality research methods were introduced; where course structure lacked detail, increased time was required for new and different online activities. These international students, from countries with a high score on Uncertainty Avoidance, exhibited that dimension when introduced to blended learning. The implications of these findings are discussed, and strategies suggested for introducing blended learning to international students. The limitations of the study are considered, and a direction for future research is suggested. This is the first study on undergraduates in the Middle East for the effects of a cultural dimension when introducing blended learning. The findings increase the body of knowledge that relates to learning technology in the international business classroom.

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

    CERN Document Server

    Jiménez, Andrea

    2011-01-01

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

  7. Student-onderwysers se interpretasie en gebruik van leerteoriekonsepte / Student teachers' interpretation and use of learning theory concepts

    Scientific Electronic Library Online (English)

    G J, van der Westhuizen; M P, van der Merwe.

    2010-03-01

    Full Text Available This article focuses on how students in one specific undergraduate training module in an undergraduate teacher education qualification present their conceptual understanding of and learning in textual format. This investigation is grounded in the cognitive flexibility theory of Spiro and co-workers. [...] This theory is regarded as meaningful in analyses of student learning and extends the more traditional views of constructivist learning such as Piaget's explication of the processes of assimilation and accommodation, as well as the theories on conceptual change to the challenges of learning in complex and weakly structured knowledge domains requiring problem solving. Construction of knowledge in real life is thus more than the act of merely recalling previous knowledge and its applications. Flexibility in the use of knowledge is therefore encouraged as every learning situation differs and, for that reason, requires the flexible use of previous knowledge. Socio-cultural perspectives on student learning are also valuable for the purpose of this investigation as they postulate that learning and meaning occur anew within each knowledge domain and situation context. Student learning is also considered from eco-social and semiotic perspectives. Semiotics is the study of signs and sign systems and what they contribute to the process of constructing knowledge and meaning. Semiotic tools investigated in this article include all aspects of human sign creation and usage. Learning texts developed by learners are also regarded as the reality of meaning for them and are influenced by social and cultural activities. Furthermore, the manner and pattern in which signs are created and creatively used by learners are related to the underlying social rules, meanings and contexts accompanying the use of signs as internalised and used by learners. The conventions of tertiary academic studies as semiotic field, which especially includes the custom of expecting from students to communicate their knowledge of concepts in writing, is also regarded as part of social events and as such, part of an interactive process of knowledge and meaning creation. Student learning is therefore considered as a process where students make use of certain semiotic instruments and sign systems to present their knowledge and interpretation. These knowledge constructions are co-determined by the semiotic domain as well as by the textual formats in which students present their knowledge. A purposive selection of four undergraduate education students according to gender, vernacular and area of specialisation was made from an initial group of students who had voluntarily taken part in a study on study team learning in a second study year undergraduate module in Teacher Education. A comparative case study of these students was undertaken. Data were collected by way of an open-ended concept clarification questionnaire as well as an assessed module assignment, answers to a module test, and module learning journals. Analyses focused on students' content interpretation of specific concepts studied in the module, how students' understanding and knowledge of these concepts were formed, as well as the semiotic instruments they employed to construct their knowledge, and how these were presented in textual formats. In addition, the data were analysed in terms of the conventions of the discourse in the particular academic domain. The findings of the investigation indicated that students' textual presentation of their knowledge and interpretation of specific learning theory concepts largely agree with the module material; that students differed in their use of semiotic instruments to construct knowledge of learning theory concepts; that discourse practices used by students to communicate their knowledge textually differed; and that the textual communication of concept knowledge in the context of students' area of specialisation was largely co-determined by the social conventions of the academic domain. Noticeable differences between selected students related to

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

    Directory of Open Access Journals (Sweden)

    Toru Tamaki

    2011-07-01

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

  9. Children's assignment of grammatical roles in the online processing of Mandarin passive sentences.

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

    2013-11-01

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

    We consider the problems of finding the lexicographically minimal (or maximal) satisfying assignment of propositional formulae for different restricted formula classes. It turns out that for each class from our framework, the above problem is either polynomial time solvable or complete for OptP. We also consider the problem of deciding if in the optimal assignment the largest variable gets value 1. We show that this problem is either in P or P^NP complete.

  5. Exploiting image registration for automated resonance assignment in NMR.

    Science.gov (United States)

    Strickland, Madeleine; Stephens, Thomas; Liu, Jian; Tjandra, Nico

    2015-06-01

    Analysis of protein NMR data involves the assignment of resonance peaks in a number of multidimensional data sets. To establish resonance assignment a three-dimensional search is used to match a pair of common variables, such as chemical shifts of the same spin system, in different NMR spectra. We show that by displaying the variables to be compared in two-dimensional plots the process can be simplified. Moreover, by utilizing a fast Fourier transform cross-correlation algorithm, more common to the field of image registration or pattern matching, we can automate this process. Here, we use sequential NMR backbone assignment as an example to show that the combination of correlation plots and segmented pattern matching establishes fast backbone assignment in fifteen proteins of varying sizes. For example, the 265-residue RalBP1 protein was 95.4% correctly assigned in 10 s. The same concept can be applied to any multidimensional NMR data set where analysis comprises the comparison of two variables. This modular and robust approach offers high efficiency with excellent computational scalability and could be easily incorporated into existing assignment software. PMID:25828257

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

    Science.gov (United States)

    Koch, Oliver; Cole, Jason

    2011-05-01

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

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

  8. Students’ Perception on Teamwork: A Study of Course Objectives Accomplishment and Satisfaction in Higher Education

    Directory of Open Access Journals (Sweden)

    Dr. Papori Baruah

    2014-04-01

    Full Text Available The academic press and management increasingly emphasize the importance of teams for organisational success in the modern economy. The use of teams has really expanded dramatically to face the competitive challenges. According to many research studies, one of the most common skills required by new work practices and processes is the ability to work in a team. As we know- education is also a process, it has an important role in recognising the needs & importance of teamwork where teachers can encourage their students to combine different skills they have to make the most of their united efforts towards a common goal. However, it was also found that students can meet their course objectives and satisfactions only if they can work in teams and access support from their teachers. If there is a good teamwork, it results a win-win scenario where teachers are able to teach more and students are able to learn more to meet their course objectives more efficiently. Working together helps teachers learn how to be more effectively use classroom time to impart knowledge and help the students to be more committed and dedicated to gain knowledge. From team teaching to teacher-student relationship, teamwork must be present in the classrooms of all levels. So, it is very important for the administration staff of educational institutions to understand the existence of teamwork in their institutions that could influence the accomplishment of course objectives and their satisfactions. This paper is concerned with examining the students’ perceptions regarding the linkage between teamwork with their course accomplishment and satisfaction level that exist in the academic institutions of North-East Region of India. The result suggests that - allowing students to work in teams lead to faster achieving of course objectives and student satisfaction, provided the teachers really pay attention on teams and setting up the assignments for the students working on the team carefully.

    Denton, Carolyn A; Wexler, Jade; Vaughn, Sharon; Bryan, Deanna

    2008-05-01

    This study investigated the effectiveness of a multicomponent reading intervention implemented with middle school students with severe reading difficulties, all of whom had received remedial and/or special education for several years with minimal response to intervention. Participants were 38 students in grades 6-8 who had severe deficits in word reading, reading fluency, and reading comprehension. Most were Spanish-speaking English language learners (ELLs) with identified disabilities. Nearly all demonstrated severely limited oral vocabularies in English and, for ELLs, in both English and Spanish. Students were randomly assigned to receive the research intervention (n = 20) or typical instruction provided in their school's remedial reading or special education classes (n = 18). Students in the treatment group received daily explicit and systematic small-group intervention for 40 minutes over 13 weeks, consisting of a modified version of a phonics-based remedial program augmented with English as a Second Language practices and instruction in vocabulary, fluency, and comprehension strategies. Results indicated that treatment students did not demonstrate significantly higher outcomes in word recognition, comprehension, or fluency than students who received the school's typical instruction and that neither group demonstrated significant growth over the course of the study. Significant correlations were found between scores on teachers' ratings of students' social skills and problem behaviors and posttest decoding and spelling scores, and between English oral vocabulary scores and scores in word identification and comprehension. The researchers hypothesize that middle school students with the most severe reading difficulties, particularly those who are ELLs and those with limited oral vocabularies, may require intervention of considerably greater intensity than that provided in this study. Further research directly addressing features of effective remediation for these students is needed. PMID:22736893

  15. Empirical Equation Based Chirality (n, m Assignment of Semiconducting Single Wall Carbon Nanotubes from Resonant Raman Scattering Data

    Directory of Open Access Journals (Sweden)

    Md Shamsul Arefin

    2012-12-01

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

  4. WRITTEN EXAMS: CONCRETE SOLUTION TO SOLVE IMAGE-TEXT RELATION FOR VISUAL COMMUNICATION DESIGN STUDENTS (ART STUDENTS?

    Directory of Open Access Journals (Sweden)

    Abdullah Sani Kamaluddin

    2012-07-01

    Full Text Available Post modern visual culture and semiotic places great emphasis on image as well as text; consequently, learning now includes the study of both text and image that are made up of many forms of mixed media, and does not separate text from images. Visual Communication Design’s Students have seldom taken written exams, reading text, and writing assignments. Most design’s subject matter emphasize in studio productions. Thus the lecturers have seldom given exams or assignments which relate between text and images. One of design’s subject matter is photography. Most photographic lecturers had never given written exams; instead they gave photo assignments for final project. Most of the lecturers gave either written exams or studio productions, but they have seldom or never integrate the text and images. The survey research conducted on 100 communication design students in third and fifth semester, and three photographic lecturers, in Tarumanagara University. The photographic lecturers prepared learning materials, student’s presentation, and exams with combine text and images. Problem based learning was used to make students more focused on the themes and assignments. Moreover, the lecturers can facilitates student, supervise student, and provide feed back. Barrett’s photo criticism was used to help students relate text and image of photographs. Some guided question was modified from Barrett’s photo criticism model. The guided questions and images selections became important steps during delivery materials, and listed in lecturer’s presentation and student’s assignments. The guided questions and a good selection of images helped the discussion, and brought students to complex thinking.

  14. The methods that college students use to answer questions about stereochemistry involving spatial ability

    Science.gov (United States)

    Strange de Soria, Luise Ethelyn

    Introduction. The research problem investigated involved determining the spatial techniques used by students when they solved problems relating to stereochemistry using both traditional and non-traditional techniques. The main reason for undertaking this study was to determine how to help students invoke their spatial ability in solving problems during their organic chemistry courses. The project allowed students to generate their own understanding of the material, to gain experience in order to increase their knowledge, and to be actively involved in the learning process in order for true understanding to take place. Methods. The qualitative methodology for the project included a background questionnaire and the Purdue Visualization of Rotations Exam to determine the five students to be interviewed. The class participated in three multimedia lectures, an in-class assignment, and an on-line homework activity, which allowed multiple ways of incorporating the material. These activities included hand-drawing structures, making non-traditional models as well as traditional models, and computer related exercises that required differing aspects of spatial ability and engagement. Five students participated in an individual and small group interview in which rotation ability as well as visualization ability was assessed using physical molecular models as well as computer models. Results. This study is significant for the field of science education and chemistry because it determined that students with varying levels of spatial ability preferred different tools and used different skills when answering questions about stereochemistry that require spatial ability. There was a pronounced difference in the ability of low and high spatial ability students to draw and make structures that required three-dimensional aspects. A distinct preference for working with the physical model kit over the computer-enhanced program was also noted. An online resource for instructors and students of organic chemistry to use when studying stereochemistry was developed during the project. Conclusions. The potential impact on teaching and learning is that other instructors of chemistry will be able to develop problems and training sessions for their specific students that are "tailor made" to fit their students' abilities and interests. Consequently, students with either high or low spatial ability can work problems with tools that best fit their skills.

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

    International Nuclear Information System (INIS)

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

  17. Traffic assignment models in large-scale applications

    DEFF Research Database (Denmark)

    Rasmussen, Thomas Kjær

    2015-01-01

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

    Ogden, Rob; Linacre, Adrian

    2015-09-01

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

    The elderly are the most vulnerable to adverse events during and after hospitalization. This study sought to evaluate the effectiveness of a curriculum on patient safety and transitions of care for medical students during an Internal Medicine-Geriatrics Clerkship on students' knowledge, skills, and attitudes. The curriculum included didactics on patient safety, health literacy, discharge planning and transitions of care, and postdischarge visits to patients. Analysis of pre- and postassessments showed afterwards students were significantly more comfortable assessing a patient's health literacy and confident performing a medication reconciliation, providing education regarding medications, and identifying barriers during transitions. More students were able to identify the most common source of adverse events after discharge (86% vs. 62% before), risk factors for low health literacy (28% vs. 14%), and ways to assess a patient's health literacy (14% vs. 2%). It was feasible to implement a postdischarge visit assignment in an urban tertiary care setting and only required on average of approximately an one and one half hours for students to complete.

    Smith, Trevor I.; Christensen, Warren M.; Mountcastle, Donald B.; Thompson, John R.

    2015-12-01

    [This paper is part of the Focused Collection on Upper Division Physics Courses.] We report on several specific student difficulties regarding the second law of thermodynamics in the context of heat engines within upper-division undergraduate thermal physics courses. Data come from ungraded written surveys, graded homework assignments, and videotaped classroom observations of tutorial activities. Written data show that students in these courses do not clearly articulate the connection between the Carnot cycle and the second law after lecture instruction. This result is consistent both within and across student populations. Observation data provide evidence for myriad difficulties related to entropy and heat engines, including students' struggles in reasoning about situations that are physically impossible and failures to differentiate between differential and net changes of state properties of a system. Results herein may be seen as the application of previously documented difficulties in the context of heat engines, but others are novel and emphasize the subtle and complex nature of cyclic processes and heat engines, which are central to the teaching and learning of thermodynamics and its applications. Moreover, the sophistication of these difficulties is indicative of the more advanced thinking required of students at the upper division, whose developing knowledge and understanding give rise to questions and struggles that are inaccessible to novices.

  15. Airport Gate Assignment A Hybrid Model and Implementation

    CERN Document Server

    Li, Chendong

    2009-01-01

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

    2007-12-01

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

    2013-01-01

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

    2003-01-01

    Introduction The requirements of professionalism and the expected qualities of medical staff, including high moral character, motivate institutions to care about the ethical development of students during their medical education. We assessed progress in moral reasoning in a cohort of medical students over the first 3 years of their education. Methods We invited all 92 medical students enrolled at the University of Sherbrooke, Que., to complete a questionnaire on moral reasoning at the start of their first year of medical school and at the end of their third year. We used the French version of Kohlberg's Moral Judgment Interview. Responses to the questionnaire were coded by stage of moral development, and weighted average scores were assigned according to frequency of use of each stage. Results Of the 92 medical students, 54 completed the questionnaire in the fall of the first year and again at the end of their third year. The average age of the students at the end of the third year was 21 years, and 79% of the students included in the study were women. Over the 3-year period, the stage of moral development did not change substantially (i.e., by more than half a stage) for 39 (72%) of the students, shifted to a lower stage for 7 (13%) and shifted to a higher stage for 8 (15%). The overall mean change in stage was not significant (from mean 3.46 in year 1 to 3.48 in year 3, p = 0.86); however, the overall mean change in weighted average scores showed a significant decline in moral development (p = 0.028). Interpretation Temporal variations in students' scores show a levelling process of their moral reasoning. This finding prompts us to ask whether a hidden curriculum exists in the structure of medical education that inhibits rather than facilitates the development of moral reasoning. PMID:12668541

A metodologia de pesquisa é semi-experimental, envolvendo um teste de matemática com seis questões e entrevistas dirigidas. Os resultados da pesquisa revelaram que os erros na solução dos problemas-palavra aritméticos resultaram da falta de conhecimentos linguísticos, semânticos, estruturais e comunicativos; no que diz respeito aos problemas-palavra, os erros vinculam-se à lacunas no conhecimento semântico, estrutural e intuitivo. Em relação aos problemas-palavra algébricos os erros devem-se a lacunas quanto às operações matemáticas. Em síntese, os resultados mostram que a maior deficiência dos alunos relaciona-se a lacunas relativas ao conhecimento semântico, estrutural e comunicativo. Abstract in english The main objective of this research is to examine the relationship between different kinds of errors and the knowledge required to solve word problems in Arithmetic, Algebra and Geometry. Kinfong's and Holtan's framework supports the analysis of the errors, and Mayer's theory was implemented to unde [...] rstand the necessary knowledge for solving math word problems. The research methodology follows a semi-experimental method. Research tools comprise both a descriptive math test and a directed interview. The research findings revealed that students' errors when solving arithmetic word problems result from the lack of linguistic, semantic, structural and communicational knowledge; when solving the geometric word problems, the lack of semantic, intuition and structural knowledge were the cause of the students' errors. Regarding algebra word problems, miscalculation was the reason for the higher error rate. Results show that the highest deficiency is mainly related to the lack of semantic, structural and communicational knowledge.

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

    DEFF Research Database (Denmark)

    Koch, Alexander; Nafziger, Julia

    2008-01-01

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

    Full Text Available An order picking system consisting of a number of parallel unidirectional picking lines is investigated. Stock keeping units (SKUs) that are grouped by product type into distributions (DBNs) are assigned daily to available picking lines. A mathematical programming formulation and its relaxations is [...] presented. A greedy insertion and a greedy phased insertion are further introduced to obtain feasible results within usable computation times for all test cases. The walking distance of the pickers was shown to decrease by about 22 per cent compared with the current assignment approach. However, product handling and operational risk increases.

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

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

  8. Effects of an Inverted Instructional Delivery Model on Achievement of Ninth-Grade Physical Science Honors Students

    Howell, Donna

    This mixed-methods action research study was designed to assess the achievement of ninth-grade Physical Science Honors students by analysis of pre and posttest data. In addition, perceptual data from students, parents, and the researcher were collected to form a complete picture of the flipped lecture format versus the traditional lecture format. The researcher utilized a 4MAT learning cycle in two Physical Science Honors classes. One of these classes was traditionally delivered with lecture-type activities taking place inside the classroom and homework-type activities taking place at home; the other inverted, or flipped, delivered with lecture-type activities taking place outside the classroom and homework-type activities taking place inside the classroom. Existing unit pre and posttests for both classes were analyzed for differences in academic achievement. At the completion of the units, the flipped class students and parents were surveyed, and student focus groups were convened to ascertain their perceptions of the flipped classroom delivery model. Statistical analysis of posttest data revealed that there is no significant difference between the traditional lecture delivery format and the flipped delivery format. Analysis of perceptual data revealed six themes that must be considered when deciding to flip the classroom: how to hold students accountable for viewing the at-home videos, accessibility of students to the required technology, technical considerations relating to the video production, comprehension of the material both during and after viewing the videos, pedagogy of the overall flipped method, and preference for the flipped method overall. Findings revealed that students, parents, and the researcher all had a preference for the flipped class format, provided the above issues are addressed. The flipped class format encourages students to become more responsible for their learning, and, in addition, students reported that the hands-on inquiry activities done in class aided them in learning the subject matter. It is recommended, however, that before instructors decide to flip the classroom, they ensure that all students have access to needed technology, that there is a plan in place for ensuring that the students actually view the assigned videos, that they have a way to create the videos and ensure adequate quality, and that some discussion is held in class after each assigned video to ensure comprehension of the material.

    Euan Lindsay

    2008-12-01

    Full Text Available Curtin University of Technology’s Engineering faculty addresses its students as ‘student engineers’. There is a subtle but important distinction between an engineering student and a student engineer. It is a challenge to have our students make that distinction and to engage with the processes of professional engineering practice.This paper reports on an innovative first year ‘Engineering Foundations: Principles and Communications (EFPC’ unit that embeds the acquisition of communication skills in a technically based project. The project revolves around two engineering constructs: a popsicle stick bridge and a mousetrap-powered car. The design and construction of each construct is conducted by different teams of students – each team designs a bridge and constructs a car, or vice versa. Each team follows recognised procedures of process and communication for the design, tendering and production of the projects.Requiring students to work both as designers and constructors introduces them to the different communication requirements of each role. More powerfully, they also assume the role of client for each others’ engineering project, providing a valuable alternative perspective. Within this technical context the unit also teaches students to write engineering case study reports, give professional presentations on their project and work in teams. These are all principal skills that are essential in the real engineering world.The project has led to significant improvements in students’ communication skills, as well as their perceived learning outcomes. It has introduced students to essential lifelong learning skills and has challenged them to become effective communicators, better team players and more professional in their approach to engineering projects.

  1. Optimal assignment methods for ligand-based virtual screening

    2009-08-01

    Full Text Available Abstract Background Ligand-based virtual screening experiments are an important task in the early drug discovery stage. An ambitious aim in each experiment is to disclose active structures based on new scaffolds. To perform these "scaffold-hoppings" for individual problems and targets, a plethora of different similarity methods based on diverse techniques were published in the last years. The optimal assignment approach on molecular graphs, a successful method in the field of quantitative structure-activity relationships, has not been tested as a ligand-based virtual screening method so far. Results We evaluated two already published and two new optimal assignment methods on various data sets. To emphasize the "scaffold-hopping" ability, we used the information of chemotype clustering analyses in our evaluation metrics. Comparisons with literature results show an improved early recognition performance and comparable results over the complete data set. A new method based on two different assignment steps shows an increased "scaffold-hopping" behavior together with a good early recognition performance. Conclusion The presented methods show a good combination of chemotype discovery and enrichment of active structures. Additionally, the optimal assignment on molecular graphs has the advantage to investigate and interpret the mappings, allowing precise modifications of internal parameters of the similarity measure for specific targets. All methods have low computation times which make them applicable to screen large data sets.

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

  9. An automated approach to seed assignment for eye plaque brachytherapy

    International Nuclear Information System (INIS)

    Episcleral plaques are commonly used for the treatment of ocular tumours such as choroidal melanoma. Treatment planning involves the assignment of seeds to slots on the plaque to achieve a desired dose rate distribution. Seed assignment is rather straightforward if seeds are ordered on demand. However, the assignment task becomes tedious and laborious if the seeds have to be chosen from an existing stock of seeds with different activities. To date, this task has usually been performed by a human planner through trial and error. An algorithm has been developed to automate the task of seed assignment using a mixed-integer programming method. We also explore ways to simplify the problem such that the method becomes practical in most facilities. We have tested the method on three randomly chosen clinical cases from our past records, to show that the algorithm could yield solutions within a shorter time frame and with less deviation from the desired dose rate distributions, as compared with the solutions from a human counterpart.

  12. Using a Cast Iron Hand-Pump to Teach Students About Water Resources and Resource Allocation

    Science.gov (United States)

    Mailloux, B. J.; Radloff, K. A.

    2010-12-01

    Simply turning on the tap brings safe, clean, fresh-tasting water to most Americans. Students never need to consider basic concepts about water supply, including their daily water consumption and the quality of the water required for drinking. In stark contrast, the issues of water quality and quantity play a central role in people’s daily lives in the developing world. It is difficult to convey this reality to our students through lectures alone and hands-on activities are required. In order to develop an active learning based approach, we transported a traditional cast iron hand-pump and aluminum urns from Bangladesh to the United States. The hand-pump is mounted on a cooler, which acts as a water reservoir, and is now functional and easily transportable. Using this powerful demonstration tool, we have developed an active learning module we call “How far will you walk for water?”. The goal of the module is to teach students about water quantity, water quality, and resource allocation with a focus on Arsenic and Bangladesh, but the system could be applied to other areas of concern. First the students are given a quick lecture on Arsenic, its health impacts, and the extent of contamination in Bangladesh. They are then assigned a specific well, complete with a map of their village and picture of their well and a water sample (pre-spiked with arsenic to be above or below the 10 ug/L WHO limit). Next they pump the wellhead, fill an urn, walk down the hall and back, and measure the distance walked. This is compared to the distance from their village home to their private well, to safe wells belonging to neighbors and to a community well. The students then use the Hach Arsenic test kit to test the arsenic levels in their water samples and learn if their well is safe to drink. Finally, given all this information students must determine if they should continue drinking from their well or switch to a new well, even if that means making multiple, long trips each day. This module has introduced the students to important water resource concepts, such as water quality testing, usage and water delivery options. It also provides students the opportunity to consider how much time and effort to should be allocated to obtaining water given known health risks. On follow up tests we use transfer questions that ask students to select the locations for installing community wells based on a data showing contaminated wells in a village. We have utilized this module with High School, Undergraduate, and Graduate students and it excites and engages students while teaching many basic water resource issues.

  13. Assigning strains to bacterial species via the internet

    Directory of Open Access Journals (Sweden)

    Hanage William P

    2009-01-01

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

    In a predominately Black, urban high school, 54 students, selected for frequent absenteeism, completed a self concept scale, were rated by their teachers, and randomly assigned to one of three groups: eclectic group counseling, counseling through sociodrama, and control. Positive changes on posttests were attributed to the Pygmalion Effect. (SJL)

    Polycystin-1 is a large transmembrane protein mutated in the common genetic disorder autosomal dominant polycystic kidney disease. One of the predicted intracellular domains of polycystin-1 is PLAT (Polycystin-1, Lipoxygenase and Alpha Toxin), which consists of 116 amino acids and is anchored to the membrane by linkers at both ends. It is predicted to have a large number of hydrophobic residues on the surface. Assignment of the NMR spectrum was hampered by considerable line broadening, and hence a programme of site-directed mutagenesis and searching for suitable solution conditions was undertaken. The optimum construct required fusion of the GB1 domain at the N-terminus and a His tag at the C-terminus, and proved to have several additional amino acids at both ends beyond the canonical domain boundaries, as well as mutation of W3128 to alanine. Optimum solubility required 500 mM sodium chloride, and usable spectra could only be obtained by perdeuteration. Backbone assignment was made using standard triple resonance spectra and is 88 % complete. The chemical shifts obtained suggest that a loop consisting of residues 3223-3228 is mobile in solution, and that the protein is similar in structure to a prediction produced by Swiss-Model based on the structure of a homologous protein.

    Full Text Available The use of macroseismic data in assessing parameters for historical earthquakes for use in seismic hazard assessment has thrown more attention on the way in which these data are treated. The processes involved in selecting which macroseismic data from a historical earthquake survive to the present day can be modelled as a series of filters, most of which are outside the control of the seismologist/historian, and which cause distortion in the resulting picture of the earthquake. The ways in which the data become distorted should be taken into account when interpreting the data as intensity values. One can usefully discriminate between the certainty of an intensity assignment (how well the data fits the scale and the quality of an intensity assignment (how well one can trust that the value is a true reflection of what really happened. The expression of uncertainty is usually in the form of ranged intensity values; the expression of quality requires an extra symbol or rating of some sort. A system is presented for three types of quality problems: reliability of intensity assessment, locational certainty or uncertainty, and veracity of the original data. Each of these is treated as a binary variable, giving a final quality code ranging from 0 (best to 7 (worst. This single integer quality code preserves three types of information which can then be expanded as required by computer programs designed to handle macroseismic data.

    Full Text Available Educators are increasingly being encouraged to use more active- and problem-based-learning techniques and assignments in the classroom to improve critical and analytical thinking skills. Active learning-based courses have been purported to be more time consuming than traditional lecture methods and for many instructors have therefore proven difficult to include in many one-semester science courses. To address this problem, a series of assignments was developed for use in a basic microbiology course involving sophomore-, junior-, and senior-level students from five different biology majors (environmental science, biology, biochemistry, premedicine, and physician assistant. Writing assignments included global, historical, and social themes for which a standardized grading format was established. Students also participated in a class debate in which the merits of the living microbial kingdoms were discussed, with only one kingdom being saved from an imaginary global catastrophe. Traditional lectures were facilitated by the use of a dedicated note packet developed by the instructor and specific for course content. Laboratories involved group analysis of mini-case history studies involving pathogenic microbes. Students’ perceptions of the subject were assessed using an exit questionnaire sent to 100 of the 174 students who had taken the course during the 5-year time period. The majority of the 64 students who responded were sophomores (78%, in keeping with the target audience, and their perception of the course’s challenge level was significantly higher (p < 0.03, 8.7 than their junior and senior counterparts (7.9. Students rated the most useful learning tools as case history studies (9.4 and the class debate (9.1, with the introduction of a dedicated microbiology links web page to the University website representing the sole component resulting in a statistically significant increase in students’ perceptions of the importance of the course (p < 0.03.

    General Chemistry is required for variety of baccalaureate degrees, including all medical related fields, engineering, and science majors. Depending on the institution, the prerequisite requirement for college level General Chemistry varies. The success rate for this course is low. The purpose of this study is to examine the factors influencing student academic achievement and retention in General Chemistry at the college level. In this study student achievement is defined by those students who earned grades of "C" or better. The dissertation contains in-depth studies on influence of Intermediate Algebra as a prerequisite compared to Fundamental Chemistry for student academic achievement and student retention in college General Chemistry. In addition the study examined the extent and manner in which student self-efficacy influences student academic achievement in college level General Chemistry. The sample for this part of the study is 144 students enrolled in first semester college level General Chemistry. Student surveys determined student self-efficacy level. The statistical analyses of study demonstrated that Fundamental Chemistry is a better prerequisite for student academic achievement and student retention. The study also found that student self-efficacy has no influence on student academic achievement. The significance of this study will be to provide data for the purpose of establishing a uniform and most suitable prerequisite for college level General Chemistry. Finally the variables identified to influence student academic achievement and enhance student retention will support educators' mission to maximize the students' ability to complete their educational goal at institutions of higher education.
