The emergence of advanced technologies in the last three decades and extraordinary progress in our knowledge on the basic Physical, Chemical and Biological properties of living matter has offered tremendous benefits to human beings but simultaneously highlighted the need of higher awareness and responsibility by the scientists of 21 century. Scientist is not born with ethics, nor science is ethically neutral, but there are ethical dimensions to scientific work. There is need to evolve an appropriate Code of Conduct for scientist particularly working in every field of Science. However, while considering the contents, promulgation and adaptation of Codes of Conduct for Scientists, a balance is needed to be maintained between freedom of scientists and at the same time some binding on them in the form of Code of Conducts. The use of good and safe laboratory procedures, whether, codified by law or by common practice must also be considered as part of the moral duties of scientists. It is internationally agreed that a general Code of Conduct can't be formulated for all the scientists universally, but there should be a set of 'building blocks' aimed at establishing the Code of Conduct for Scientists either as individual researcher or responsible for direction, evaluation, monitoring of scientific activities at the institutional or organizational level.

To determine perceptions of acceptable conducts amongst under and postgraduate optometry students and to compare them with students from other disciplines. Students (under/postgraduate) of optometry (n=156) and other courses (n=54) from University of Minho participated in a voluntary online questionnaire about perception of conducts, classifying as acceptable or unacceptable 15 academic or professional scenarios. 210 questionnaires were analyzed. Differences in perceptions were found between optometry under and postgraduates in scenario 5, Chi-square(2,156)=4.3, p=0.038, and scenario 7, Chi-square(2,156)=7.0, p=0.008 (both with cheating more acceptable for postgrads). Differences between under and postgraduates from other courses were found in scenario 9 (taking supplies from classroom more acceptable for undergrads), Chi-square(1,54)=5.0, p=0.025, and scenario 14 (forging a signature more acceptable for postgrads), Chi-square(1,54)=3.9, p=0.046. Differences between optometry and other courses undergraduates were observed in scenario 2 (plagiarism more acceptable for optometry undergrads), Chi-square(1,154)=8.3, p=0.004 and scenario 9 (taking supplies from classroom more acceptable for other undergrads), chi-square(1,54)=7.8, p=0.005. Differences between optometry and other courses postgraduates were observed in scenario 7, Chi-square(1,56)=5.8, p=0.016, scenario 10 (both with cheating more acceptable for optometry postgrads), chi-square(1,54)=8.1, p=0.004 and scenario 14 (forging a signature more acceptable for other postgrads), Chi-square(1,54)=6.1, p=0.026. Academic misconducts were mainly considered more acceptable than professional misconducts. Our results show that perceptions of acceptable conducts amongst optometry students are not very different from other students, and, against our initial prediction, do not show a general change in misconduct perception when students become more mature. Universities should pay more attention to this problem and take

Garrett, Paul B

2007-01-01

Designed for an advanced undergraduate- or graduate-level course, Abstract Algebra provides an example-oriented, less heavily symbolic approach to abstract algebra. The text emphasizes specifics such as basic number theory, polynomials, finite fields, as well as linear and multilinear algebra. This classroom-tested, how-to manual takes a more narrative approach than the stiff formalism of many other textbooks, presenting coherent storylines to convey crucial ideas in a student-friendly, accessible manner. An unusual feature of the text is the systematic characterization of objects by universal

Students with early-starting conduct problems often do poorly in school; they are disproportionately placed in restrictive educational placements outside of mainstream classrooms. Although intended to benefit students, research suggests that restrictive placements may exacerbate the maladjustment of youth with conduct problems. Mixed findings, small samples, and flawed designs limit the utility of existing research. This study examined the impact of restrictive educational placements on three adolescent outcomes (high school noncompletion, conduct disorder, depressive symptoms) in a sample of 861 students with early-starting conduct problems followed longitudinally from kindergarten (age 5-6). Causal modeling with propensity scores was used to adjust for confounding factors associated with restrictive placements. Analyses explored the timing of placement (elementary vs. secondary school) and moderation of impact by initial problem severity. Restrictive educational placement in secondary school (but not in elementary school) was iatrogenic, increasing the risk of high school noncompletion and the severity of adolescent conduct disorder. Negative effects were amplified for students with conduct problem behavior with less cognitive impairment. To avoid harm to students and to society, schools must find alternatives to restrictive placements for students with conduct problems in secondary school, particularly when these students do not have cognitive impairments that might warrant specialized educational supports. © 2015 Association for Child and Adolescent Mental Health.

Niswatin, C.; Latief, M. A.; Suharyadi, S.

2018-02-01

This research aims to uncover the fact about engineering students in dealing with composing abstracts for their final projects. The research applies a descriptive qualitative quantitative design. The data were collected through questioners involving 104 engineering students, including the alumni at Politeknik Kota Malang, Indonesia. Furthermore, interviews were carried out to explain the details where necessary to support the primary data. It is found that the common problems faced by engineering students include 1) combining words into sentences, 2) identifying the most appropriate technical terms in engineering, and 3) applying grammar in context. To cope with those difficulties they demanded translation application machines, supported by peer-proofreaders. In addition, they considerably engaged personal tutoring with the lectures more than three times.

Learning abstract algebra with ISETL

CERN Document Server

Dubinsky, Ed

1994-01-01

Most students in abstract algebra classes have great difficulty making sense of what the instructor is saying. Moreover, this seems to remain true almost independently of the quality of the lecture. This book is based on the constructivist belief that, before students can make sense of any presentation of abstract mathematics, they need to be engaged in mental activities which will establish an experiential base for any future verbal explanation. No less, they need to have the opportunity to reflect on their activities. This approach is based on extensive theoretical and empirical studies as well as on the substantial experience of the authors in teaching astract algebra. The main source of activities in this course is computer constructions, specifically, small programs written in the mathlike programming language ISETL; the main tool for reflections is work in teams of 2-4 students, where the activities are discussed and debated. Because of the similarity of ISETL expressions to standard written mathematics...

The deep learning in Optics can be encouraged by stimulating and considerate teaching. It means that teacher should demonstrate his/her personal commitment to the subject and stress its meaning, relevance and importance to the students. It is also important to allow students to be creative in solving problems and in interpretation of its contents. In order to help the students to become more creative persons it is necessary to enhance the learning process of modern knowledge in Optics, to design and conduct experiments, stimulate passions and interests, allow an access to the e-learning system (Internet) and introduce the psychological training (creativity, communication, lateral thinking etc.) (Abstract only available)

Farida Nurhasanah

2017-02-01

Full Text Available In attempt to explain how students learning geometry in concept of triangle, this study explore the learning process of students and the process of solving geometry problems in the topic of triangle.  As known as one of the domain in school of mathematics, geometry has abstract notions to be learnt so that all those notions cannot be just transferred into students’ mind like a bunch of information that should be memorized. Students need to construct those concepts during their learning process. This process of knowledge construction can be considered as an abstraction process. This study aimed to qualitatively compare students’ abstraction process who learn topic of triangle in conventional method of teaching and in van Hiele model of teaching aided by Geometers’ sketchpad. Subjects of this study were junir high school students in grade 7. Based on the aims of this study, this is a qualitative study with grounded theory design. Data were collected through classroom observation, test, and task-based interview. Results of the study show that theoretical abstraction processes tend to dominate classrom with conventional method of teaching while classroom with van Hiele model of teaching aided by Geometers’ sketchpad accommodated empirical abstraction process of the students

Development of abstract mathematical reasoning: the case of algebra.

Science.gov (United States)

Susac, Ana; Bubic, Andreja; Vrbanc, Andrija; Planinic, Maja

2014-01-01

Algebra typically represents the students' first encounter with abstract mathematical reasoning and it therefore causes significant difficulties for students who still reason concretely. The aim of the present study was to investigate the developmental trajectory of the students' ability to solve simple algebraic equations. 311 participants between the ages of 13 and 17 were given a computerized test of equation rearrangement. Equations consisted of an unknown and two other elements (numbers or letters), and the operations of multiplication/division. The obtained results showed that younger participants are less accurate and slower in solving equations with letters (symbols) than those with numbers. This difference disappeared for older participants (16-17 years), suggesting that they had reached an abstract reasoning level, at least for this simple task. A corresponding conclusion arises from the analysis of their strategies which suggests that younger participants mostly used concrete strategies such as inserting numbers, while older participants typically used more abstract, rule-based strategies. These results indicate that the development of algebraic thinking is a process which unfolds over a long period of time. In agreement with previous research, we can conclude that, on average, children at the age of 15-16 transition from using concrete to abstract strategies while solving the algebra problems addressed within the present study. A better understanding of the timing and speed of students' transition from concrete arithmetic reasoning to abstract algebraic reasoning might help in designing better curricula and teaching materials that would ease that transition.

Full Text Available Introduction: E-learning includes various categories of media that distribute text, audio, images, animation, and streaming video, and includes technology applications and processes, computer-based learning, as well as local intranet/extranet learning. Information and communication systems motivate many e-learning processes. E-learning can occur in or out of the classroom. ILIAS (Integriertes Lern-, Informations- und Arbeitskooperations-System [German for "Integrated Learning, Information and Work Cooperation System"] is an open source web-based learning management system (LMS. It supports learning content management and tools for collaboration, communication, evaluation, and assessment for University students. Materials and Methods: First year medical students were requested to register in Yengage, and the date of the assessment was announced. Twenty MCQ from cardiovascular system was preloaded in the Yengage portal, and the students used their personal laptop to answer the questions within the stipulated time. The results were automatically loaded at the end of the assessment. Pre- and post-test was conducted to investigate the usefulness of the E- assessment. Results: The students responded that the E-assessment was easy to assess, unique as they received immediate feedback, customized and flexible. There was significant difference in the post-test score when compared to the pre-test score. Discussion: Technology has created new methods of assessment for today′s generation of students, and these advances are here to stay. Conclusion: It is possible to conduct online examinations in medical school regularly. The e-learning can enhance student interests and allows immediate feedback. Since e-learning is not well-established in India, we hope to create awareness and change the outlook of medical students in online teaching-learning and assessment program.

Limited literature examines mathematics education for students with mild intellectual disability. This study investigated the effects of using the Virtual-Abstract instructional sequenceto teach middle school students, predominantly with mild intellectual disability, to add fractions of unlike denominators. Researchers used a multiple probe across participants design to determine if a functional relation existed between the Virtual-Abstract instructional sequence strategy and students' ability to add fractions with unlike denominators. The study of consisted of three-to-nine baseline sessions, 6-11 intervention sessions, and two maintenance sessions for each student. Data were collected on accuracy across five addition of fractions with unlike denominators problems. The VA instructional strategy was effective in thestudents to add fractions with unlike denominators; a functional relation existed between the VA instructional sequence and adding fractions with unlike denominators for three of the four students. The Virtual-Abstract instructional sequencemay be appropriate to support students with mild intellectual disability in learning mathematics, especially when drawing or representing the mathematical concepts may prove challenging.

Analogical scaffolding and the learning of abstract ideas in physics: Empirical studies

Directory of Open Access Journals (Sweden)

Noah S. Podolefsky

2007-09-01

Full Text Available Previously, we proposed a model of student reasoning which combines the roles of representation, analogy, and layering of meaning—analogical scaffolding [Podolefsky and Finkelstein, Phys. Rev. ST Phys. Educ. Res. 3, 010109 (2007]. The present empirical studies build on this model to examine its utility and demonstrate the vital intertwining of representation, analogy, and conceptual learning in physics. In two studies of student reasoning using analogy, we show that representations couple to students’ existing prior knowledge and also lead to the dynamic formation of new knowledge. Students presented with abstract, concrete, or blended (both abstract and concrete representations produced markedly different response patterns. In the first study, using analogies to scaffold understanding of electromagnetic (EM waves, students in the blend group were more likely to reason productively about EM waves than students in the abstract group by as much as a factor of 3 (73% vs 24% correct, p=0.002. In the second study, examining representation use within one domain (sound waves, the blend group was more likely to reason productively about sound waves than the abstract group by as much as a factor of 2 (48% vs 23% correct, p=0.002. Using the analogical scaffolding model we examine when and why students succeed and fail to use analogies and interpret representations appropriately.

Analogical scaffolding and the learning of abstract ideas in physics: Empirical studies

2007-09-01

Full Text Available Previously, we proposed a model of student reasoning which combines the roles of representation, analogy, and layering of meaning—analogical scaffolding [Podolefsky and Finkelstein, Phys. Rev. ST Phys. Educ. Res. 3, 010109 (2007]. The present empirical studies build on this model to examine its utility and demonstrate the vital intertwining of representation, analogy, and conceptual learning in physics. In two studies of student reasoning using analogy, we show that representations couple to students’ existing prior knowledge and also lead to the dynamic formation of new knowledge. Students presented with abstract, concrete, or blended (both abstract and concrete representations produced markedly different response patterns. In the first study, using analogies to scaffold understanding of electromagnetic (EM waves, students in the blend group were more likely to reason productively about EM waves than students in the abstract group by as much as a factor of 3 (73% vs 24% correct, p=0.002 .

Full Text Available Understanding complex socio-environmental problems requires specialists from multiple disciplines to integrate research efforts. Programs such as the National Science Foundation's Integrative Graduate Education and Research Traineeship facilitate integrated research efforts and change the way academic institutions train future leaders and scientists. The University of Idaho and the Tropical Agricultural Research and Higher Education Center in Costa Rica collaborate on a joint research program focusing on biodiversity conservation and sustainable production in fragmented landscapes. We first present a spectrum of integration ranging from disciplinary to transdisciplinary across seven aspects of the research process. We then describe our experiences and lessons learned conducting interdisciplinary graduate student team research. Using our program as a case study, we examine the individual, disciplinary, and programmatic bridges and barriers to conducting interdisciplinary research that emerged during our student team research projects. We conclude with a set of recommendations for exploiting the bridges and overcoming the barriers to conducting interdisciplinary research, especially as part of graduate education programs.

(Abstract only) The AAVSO is in the process of expanding its education, outreach and speakers bureau program. powerpoint presentations prepared for specific target audiences such as AAVSO members, educators, students, the general public, and Science Olympiad teams, coaches, event supervisors, and state directors will be available online for members to use. The presentations range from specific and general content relating to stellar evolution and variable stars to specific activities for a workshop environment. A presentation—even with a general topic—that works for high school students will not work for educators, Science Olympiad teams, or the general public. Each audience is unique and requires a different approach. The current environment necessitates presentations that are captivating for a younger generation that is embedded in a highly visual and sound-bite world of social media, twitter and U-Tube, and mobile devices. For educators, presentations and workshops for themselves and their students must support the Next Generation Science Standards (NGSS), the Common Core Content Standards, and the Science Technology, Engineering and Mathematics (STEM) initiative. Current best practices for developing relevant and engaging powerpoint presentations to deliver information to a variety of targeted audiences will be presented along with several examples.

Wadsworth, A R

2017-01-01

This is a book of problems in abstract algebra for strong undergraduates or beginning graduate students. It can be used as a supplement to a course or for self-study. The book provides more variety and more challenging problems than are found in most algebra textbooks. It is intended for students wanting to enrich their learning of mathematics by tackling problems that take some thought and effort to solve. The book contains problems on groups (including the Sylow Theorems, solvable groups, presentation of groups by generators and relations, and structure and duality for finite abelian groups); rings (including basic ideal theory and factorization in integral domains and Gauss's Theorem); linear algebra (emphasizing linear transformations, including canonical forms); and fields (including Galois theory). Hints to many problems are also included.

Adaptation and extension of the framework of reducing abstraction in the case of differential equations

Science.gov (United States)

Raychaudhuri, Debasree

2014-01-01

Although there is no consensus in regard to a unique meaning for abstraction, there is a recognition of the existence of several theories of abstraction, and that the ability to abstract is imperative to learning and doing meaningful mathematics. The theory of reducing abstraction maps the abstract nature of mathematics to the nature of knowledge construction by offering three interpretations of how students reduce abstraction while learning mathematical concepts. We apply this framework to explain students' cognition processes as they construct the concept of solution to differential equations and related concepts during a semester long study. Additionally, we refine and extend the framework to elucidate various nuances of the interplay between mathematical structures and human thoughts.

Mathematical Abstraction: Constructing Concept of Parallel Coordinates

Science.gov (United States)

Nurhasanah, F.; Kusumah, Y. S.; Sabandar, J.; Suryadi, D.

2017-09-01

Mathematical abstraction is an important process in teaching and learning mathematics so pre-service mathematics teachers need to understand and experience this process. One of the theoretical-methodological frameworks for studying this process is Abstraction in Context (AiC). Based on this framework, abstraction process comprises of observable epistemic actions, Recognition, Building-With, Construction, and Consolidation called as RBC + C model. This study investigates and analyzes how pre-service mathematics teachers constructed and consolidated concept of Parallel Coordinates in a group discussion. It uses AiC framework for analyzing mathematical abstraction of a group of pre-service teachers consisted of four students in learning Parallel Coordinates concepts. The data were collected through video recording, students’ worksheet, test, and field notes. The result shows that the students’ prior knowledge related to concept of the Cartesian coordinate has significant role in the process of constructing Parallel Coordinates concept as a new knowledge. The consolidation process is influenced by the social interaction between group members. The abstraction process taken place in this group were dominated by empirical abstraction that emphasizes on the aspect of identifying characteristic of manipulated or imagined object during the process of recognizing and building-with.

2018-06-01

Full Text Available In order to foster leaders and supporters of fixed-point observation for sustainable forest management, it is considered effective to focus on students who have demonstrated potential for fixed-point observations of forests in the universal education stage. This study aims to identify the characteristics of students who frequently conduct plant observations, which is the basis for the fixed-point observation of forests, including methods involving photography. We conducted a questionnaire survey, which consisted of 19 questions that provided insight into junior high school students’ experiences, opportunities, and interests related to plant observation. We compared students who have conducted plant observations with those who have not, using Fisher’s exact test and multiple comparisons using the Benjamini and Hochberg method. The ratio of students who frequently conducted plant observations was significantly higher among female students than male students, and their characteristics differed by gender. The significant characteristics of male students included farm work experience and niche hobbies such as camping and lighting a bonfire, as well as using digital single-lens reflex cameras for photography; female students had relatively niche hobbies such as enjoying science. Students who increased the frequency of plant observations after the lecture about fixed-point observations of forests had an inclination toward social studies and tended not to use a smartphone for photography.

Food intake of university students

Directory of Open Access Journals (Sweden)

Greyce Luci BERNARDO

Full Text Available ABSTRACT This narrative literature review aimed to analyze the results of studies on the food intake of university students. A literature search was conducted in July 2014 and updated in July 2016 in the Scopus, MedLine/PubMed, and SciELO databases, using descriptors related to university students and food intake in English and Portuguese. Overall, 37 studies that analyzed university students’ food intake were included in this review, eight of which were conducted in Brazil. The results demonstrated that most university students have unhealthy eating behaviors, such as high intake of fast foods, snacks, sweets, soft drinks, and alcoholic beverages, and low intake of fruits, vegetables, fish, whole grains, and legumes. Undergraduate students of health sciences, such as nursing, nutrition, and medicine, did not have healthier diets. University students’ food intake was characterized as unhealthy, regardless of undergraduate program or sex, especially among students who left the parents’ home and became responsible for their own food. Therefore, there is a need of developing public policies that promote healthy eating habits among students, such as interventions to change their eating habits and increase their access to healthy foods at the university environment.

Looking for the Forest and the Trees: Exercises to Provoke Abstract Thinking

Directory of Open Access Journals (Sweden)

Boriana Marintcheva

2013-02-01

Full Text Available It is probably hard to find an educator who would hesitate to agree that abstract thinking and comfort in asking questions are pivotal to scientific inquiry and advancement of knowledge. Yet, most of the time the mechanics of fostering these skills is as challenging as photographing dense fog.  As biologists we constantly reevaluate what we know, how we think about what we know, and how we communicate our knowledge about the living world. These short engaging exercises challenge students to appreciate the central role of abstract thinking and question asking in scientific inquiry.  In the first exercise the classroom is presented with an optical illusion image and challenged to evaluate it using concrete and abstract thinking tools. In a follow up exercise, students are prompted to evaluate the process of making assumptions, asking questions and coming to conclusions using the example of a small popular culture article. Both exercises are used as primers to stimulate discussion emphasizing that abstract thinking and question asking are critical tools in the tool set of 21st century budding biologists.

Shirley REUSHLE

2008-07-01

Full Text Available ABSTRACT This paper reports on the trial of web conferencing software conducted at a regional Australian university with a significant distance population. The paper shares preliminary findings, the views of participants and recommendations for future activity. To design and conduct the trial, an action research method was chosen because it is participative and grounded in experience, reflecting the context and objectives of the trial. In the first phase of the trial, students in postgraduate Education courses were linked across the globe to participate in interactive and collaborative conference activity and to communicate via audio, text, and video and shared whiteboard. Mathematical problem-solving was carried out collaboratively in an undergraduate course using tablet PCs. This was followed by phase 2, a university-wide trial across disciplines. Preliminary findings indicate that web conferencing software enables teachers and students at the university to engage actively across diverse locations, supporting a student-centred approach and greater flexibility in terms of where, when and how students learn. From these findings, the authors have made some initial recommendations to university management on the adoption of web conferencing to support learning and teaching.

An introduction to abstract algebra

CERN Document Server

Robinson, Derek JS

2003-01-01

This is a high level introduction to abstract algebra which is aimed at readers whose interests lie in mathematics and in the information and physical sciences. In addition to introducing the main concepts of modern algebra, the book contains numerous applications, which are intended to illustrate the concepts and to convince the reader of the utility and relevance of algebra today. In particular applications to Polya coloring theory, latin squares, Steiner systems and error correcting codes are described. Another feature of the book is that group theory and ring theory are carried further than is often done at this level. There is ample material here for a two semester course in abstract algebra. The importance of proof is stressed and rigorous proofs of almost all results are given. But care has been taken to lead the reader through the proofs by gentle stages. There are nearly 400 problems, of varying degrees of difficulty, to test the reader''s skill and progress. The book should be suitable for students ...

Shared liking and association valence for representational art but not abstract art.

Science.gov (United States)

Schepman, Astrid; Rodway, Paul; Pullen, Sarah J; Kirkham, Julie

2015-01-01

We examined the finding that aesthetic evaluations are more similar across observers for representational images than for abstract images. It has been proposed that a difference in convergence of observers' tastes is due to differing levels of shared semantic associations (Vessel & Rubin, 2010). In Experiment 1, student participants rated 20 representational and 20 abstract artworks. We found that their judgments were more similar for representational than abstract artworks. In Experiment 2, we replicated this finding, and also found that valence ratings given to associations and meanings provided in response to the artworks converged more across observers for representational than for abstract art. Our empirical work provides insight into processes that may underlie the observation that taste for representational art is shared across individual observers, while taste for abstract art is more idiosyncratic.

ABSTRACT Objective: The main aim of this research is to investigate the prevalence of bullying behaviour, its victims and the types of bullying and places of bullying among 14-17 year-old adolescents in a sample of school children in Bursa, Turkey. Methodology: A cross-sectional survey questionnaire was conducted among class 1 and class 2 high school students for identification bullying. Results: Majority (96.7%) of the students were involved in bullying behaviours as aggressors or victims. For a male student, the likelihood of being involved in violent behaviours was detected to be nearly 8.4 times higher when compared with a female student. Conclusion: a multidisciplinary approach involving affected children, their parents, school personnel, media, non-govermental organizations, and security units is required to achieve an effective approach for the prevention of violence targeting children in schools as victims and/or perpetrators.

Embodied cognition, abstract concepts, and body manipulation

Directory of Open Access Journals (Sweden)

Katinka eDijkstra

2014-08-01

Full Text Available Current approaches on cognition hold that concrete concepts are grounded in concrete experiences. There is no consensus, however, as to whether this is equally true for abstract concepts. In this review we discuss how the body might be involved in understanding abstract concepts through metaphor activation. Substantial research has been conducted on the activation of common orientational metaphors with bodily manipulations, such as ‘power is up’ and ‘more is up’ representations. We will focus on the political metaphor that has a more complex association between the concept and the concrete domain. However, the outcomes of studies on this political metaphor have not always been consistent, possibly because the experimental manipulation was not implicit enough. The inclusion of new technological devices in this area of research, such as the Wii Balance Board, seems promising in order to assess the groundedness of abstract conceptual spatial metaphors in an implicit manner. This may aid further research to effectively demonstrate the interrelatedness between the body and more abstract representations.

Yusepa, B. G. P.; Kusumah, Y. S.; Kartasasmita, B. G.

2018-01-01

The aim of this study is to get an in-depth understanding of students’ abstract-thinking ability in mathematics learning. This study was an experimental research with pre-test and post-test control group design. The subject of this study was eighth-grade students from two junior high schools in Bandung. In each schools, two parallel groups were selected and assigned into control and experimental groups. The experimental group was exposed to Cognitive Apprenticeship Instruction (CAI) treatment, whereas the control group was exposed to conventional learning. The results showed that abstract-thinking ability of students in experimental group was better than that of those in control group in which it could be observed from the overall and school level. It could be concluded that CAI could be a good alternative learning model to enhance students’ abstract-thinking ability.

Full Text Available We report a design study that assessed the feasibility of Enacted Reading Comprehension (ERC, an intervention designed to teach 3rd and 4th grade students (n = 40 and 25, respectively to use gestures to understand an increasingly abstract set of texts. Students were taught to use gestures to understand the idea of "opposing forces" in a concrete setting-the forces at play as tectonic plates move past each other-and then taught to use the gestures to understand opposing forces in more abstract situations. For example, students were taught to use gestures to understand the opposing sides of an argument, and to understand the internal conflicts that arise as individuals are faced with moral dilemmas. The results of our design study suggest that ERC has promise as a method for introducing students to the idea of using gesture to understand text content, and to employ this strategy in a range of reading contexts.

Maupin, Julia A.

2001-05-19

The Interfacing Microbiology and Biotechnology Conference was attended by over 100 faculty, post-docs, students, and research scientists from the US, Europe, and Latin America. The conference successfully stimulated communication and the dissemination of knowledge among scientists involved in basic and applied research. The focus of the conference was on microbial physiology and genetics and included sessions on C1 metabolism, archaeal metabolism, proteases and chaperones, gene arrays, and metabolic engineering. The meeting provided the setting for in-depth discussions between scientists who are internationally recognized for their research in these fields. The following objectives were met: (1) The promotion of interaction and future collaborative projects among scientists involved in basic and applied research which incorporates microbial physiology, genetics, and biochemistry; (2) the facilitation of communication of new research findings through seminars, posters, and abstracts; (3 ) the stimulation of enthusiasm and education among participants including graduate and undergraduate students.

Full-text publication of abstract-presented work in sport and exercise psychology.

Meetings promote information sharing, but do not enable full dissemination of details. A systematic search was conducted for abstracts presented at the 2010 and 2011 Association of Applied Sport Psychology Annual Conferences to determine the full-text dissemination rate of work presented in abstract form and investigate factors influencing this rate. Systematic searches were sequentially conducted to determine whether the abstract-presented work had been published in full-text format in the 5 years following presentation. If a potential full-text publication was identified, information from the conference abstract (eg, results, number of participants in the sample(s), measurement tools used and so on) was compared with the full text to ensure the two entities represented the same body of work. Abstract factors of interest were assessed using logistic regression. Ninety-four out of 423 presented abstracts (22.2%) were published in full text. Odds of full-text publication increased if the abstract was from an international institution, presented in certain conference sections or presented as a lecture. Those attending professional conferences should be cautious when translating data presented at conferences into their applied work because of the low rate of peer-reviewed and full-text publication of the information.

Grounding abstractness: Abstract concepts and the activation of the mouth

Directory of Open Access Journals (Sweden)

Anna M Borghi

2016-10-01

Full Text Available One key issue for theories of cognition is how abstract concepts, such as freedom, are represented. According to the WAT (Words As social Tools proposal, abstract concepts activate both sensorimotor and linguistic/social information, and their acquisition modality involves the linguistic experience more than the acquisition of concrete concepts. We report an experiment in which participants were presented with abstract and concrete definitions followed by concrete and abstract target-words. When the definition and the word matched, participants were required to press a key, either with the hand or with the mouth. Response times and accuracy were recorded. As predicted, we found that abstract definitions and abstract words yielded slower responses and more errors compared to concrete definitions and concrete words. More crucially, there was an interaction between the target-words and the effector used to respond (hand, mouth. While responses with the mouth were overall slower, the advantage of the hand over the mouth responses was more marked with concrete than with abstract concepts. The results are in keeping with grounded and embodied theories of cognition and support the WAT proposal, according to which abstract concepts evoke linguistic-social information, hence activate the mouth. The mechanisms underlying the mouth activation with abstract concepts (re-enactment of acquisition experience, or re-explanation of the word meaning, possibly through inner talk are discussed. To our knowledge this is the first behavioral study demonstrating with real words that the advantage of the hand over the mouth is more marked with concrete than with abstract concepts, likely because of the activation of linguistic information with abstract concepts.

Yang, Quan

2001-10-01

This study, involving 154 undergraduate college students in China, was conducted to determine whether the surface structure of visual graphics affect content learning when the learner was a non-native English speaker and learning took place in a non-English speaking environment. Instruction with concrete animated graphics resulted in significantly higher achievement, when compared to instruction with concrete static, abstract static, abstract animated graphics or text only without any graphical illustrations. It was also found, unexpectedly, the text-only instruction resulted in the second best achievement, significantly higher than instruction with concrete static, abstract static, and abstract animated graphics. In addition, there was a significant interaction with treatment and test item, which indicated that treatment effects on graphic-specific items differed from those on definitional items. Additional findings indicated that relation to graphics directly or indirectly from the text that students studied had little impact on their performance in the posttests. Further, 51% of the participants indicated that they relied on some graphical images to answer the test questions and 19% relied heavily on graphics when completing the tests. In conclusion, concrete graphics when combined with animation played a significant role in enhancing ESL student performance and enabled the students to achieve the best learning outcomes as compared to abstract animated, concrete static, and abstract static graphics. This result suggested a significant innovation in the design and development of ESL curriculum in computer-based instruction, which would enable ESL students to perform better and achieve the expected outcomes in content area learning.

Responsibility for proving and defining in abstract algebra class

Science.gov (United States)

Fukawa-Connelly, Timothy

2016-07-01

There is considerable variety in inquiry-oriented instruction, but what is common is that students assume roles in mathematical activity that in a traditional, lecture-based class are either assumed by the teacher (or text) or are not visible at all in traditional math classrooms. This paper is a case study of the teaching of an inquiry-based undergraduate abstract algebra course. In particular, gives a theoretical account of the defining and proving processes. The study examines the intellectual responsibility for the processes of defining and proving that the professor devolved to the students. While the professor wanted the students to engage in all aspects of defining and proving, he was only successful at devolving responsibility for certain aspects and much more successful at devolving responsibility for proving than conjecturing or defining. This study suggests that even a well-intentioned instructor may not be able to devolve responsibility to students for some aspects of mathematical practice without using a research-based curriculum or further professional development.

Lachner, Andreas; Nückles, Matthias

2015-03-01

Experts' explanations have been shown to better enhance novices' transfer as compared with advanced students' explanations. Based on research on expertise and text comprehension, we investigated whether the abstractness or the cohesion of experts' and intermediates' explanations accounted for novices' learning. In Study 1, we showed that the superior cohesion of experts' explanations accounted for most of novices' transfer, whereas the degree of abstractness did not impact novices' transfer performance. In Study 2, we investigated novices' processing while learning with experts' and intermediates' explanations. We found that novices studying experts' explanations actively self-regulated their processing of the explanations, as they showed mainly deep-processing activities, whereas novices learning with intermediates' explanations were mainly engaged in shallow-processing activities by paraphrasing the explanations. Thus, we concluded that subject-matter expertise is a crucial prerequisite for instructors. Despite the abstract character of experts' explanations, their subject-matter expertise enables them to generate highly cohesive explanations that serve as a valuable scaffold for students' construction of flexible knowledge by engaging them in deep-level processing.

The left inferior frontal gyrus: A neural crossroads between abstract and concrete knowledge.

Science.gov (United States)

Della Rosa, Pasquale Anthony; Catricalà, Eleonora; Canini, Matteo; Vigliocco, Gabriella; Cappa, Stefano F

2018-07-15

Evidence from both neuropsychology and neuroimaging suggests that different types of information are necessary for representing and processing concrete and abstract word meanings. Both abstract and concrete concepts, however, conjointly rely on perceptual, verbal and contextual knowledge, with abstract concepts characterized by low values of imageability (IMG) (low sensory-motor grounding) and low context availability (CA) (more difficult to contextualize). Imaging studies supporting differences between abstract and concrete concepts show a greater recruitment of the left inferior frontal gyrus (LIFG) for abstract concepts, which has been attributed either to the representation of abstract-specific semantic knowledge or to the request for more executive control than in the case of concrete concepts. We conducted an fMRI study on 27 participants, using a lexical decision task involving both abstract and concrete words, whose IMG and CA values were explicitly modelled in separate parametric analyses. The LIFG was significantly more activated for abstract than for concrete words, and a conjunction analysis showed a common activation for words with low IMG or low CA only in the LIFG, in the same area reported for abstract words. A regional template map of brain activations was then traced for words with low IMG or low CA, and BOLD regional time-series were extracted and correlated with the specific LIFG neural activity elicited for abstract words. The regions associated to low IMG, which were functionally correlated with LIFG, were mainly in the left hemisphere, while those associated with low CA were in the right hemisphere. Finally, in order to reveal which LIFG-related network increased its connectivity with decreases of IMG or CA, we conducted generalized psychophysiological interaction analyses. The connectivity strength values extracted from each region connected with the LIFG were correlated with specific LIFG neural activity for abstract words, and a regression

Individual differences in recognising involuntary autobiographical memories: impact on the reporting of abstract cues.

Science.gov (United States)

Mace, John H; Bernas, Ronan S; Clevinger, Amanda

2015-01-01

This study examined individual differences in the ability to recognise involuntary autobiographical memories. We hypothesised that individuals may not always recognise involuntary memories which are cued by abstract experiences (e.g., thoughts or language), while they are better able to recognise those which are cued by concrete sensory/perpetual experiences. We hypothesised that individuals without formal training in psychology would be more prone to these recognition failures than individuals with training in psychology. We tested the hypothesis by comparing the results of general first-year undergraduate students, graduate students in psychology and graduates students in other disciplines after each had participated in a two-week diary study of their naturally occurring involuntary memories. The results showed undergraduate participants and non-psychology graduate participants reporting fewer involuntary memories being triggered by abstract cues than the graduate psychology participants, while the groups did not differ in the report of memories triggered by sensory/perpetual cues. The implications of the findings are discussed.

Abdolrahimi, Mahbobeh; Ghiyasvandian, Shahrzad; Zakerimoghadam, Masoumeh; Ebadi, Abbas

2018-01-01

Health communication (HC) is considered an important task of nurses to provide high quality and holistic care as well as to improve patient health. The nursing student-patient HC is an abstract concept and needs to be clarified. Therefore, this study was conducted to increase the knowledge about nursing students' HC with patients by considering various participants' viewpoints. In this conventional qualitative content analysis, 18 semi-structured interviews were conducted with six nursing students, six nursing instructors, and six patients in educational hospitals affiliated to the University of Medical Sciences. Credibility, confirmability, dependability, and transferability were established to validate the trustworthiness of the data. The process of data collection and analysis lasted 9 months. After data analysis, two categories were generated: (A) "junior nursing student-patient communication," with two subcategories of "performing social communication with patients" and "failure to build therapeutic relationships with patients," and (B) "senior nursing student-patient communication" with two subcategories of "establishing effective communication with patients" and "performing one-way communication with patients." More attention should be paid to improve HC through shifting towards student-centered approaches in nursing curriculum. Further, role model nurses and clinical educators should guide nursing students for institutionalizing HC in future nurses.

From mind to matter: neural correlates of abstract and concrete mindsets

Science.gov (United States)

Liberman, Nira; Maril, Anat

2014-01-01

Much work in the field of social cognition shows that adopting an abstract (vs concrete) mindset alters the way people construe the world, thereby exerting substantial effects across innumerable aspects of human behavior. In order to investigate the cognitive and neural basis of these effects, we scanned participants as they performed two widely used tasks that induce an abstracting vs concretizing mindsets. Specifically, participants: (i) indicated ‘why’ perform certain activities (a task that involves abstraction) or ‘how’ the same activities are performed (a task that involves concretization) and (ii) generated superordinate categories for certain objects (a task that involves abstraction) or subordinate exemplars for the same objects (a task that involves concretization). We conducted a conjunction analysis of the two tasks, in order to uncover the neural activity associated with abstraction and concretization. The results showed that concretization was associated with activation in fronto-parietal regions implicated in goal-directed action; abstraction was associated with activity within posterior regions implicated in visual perception. We discuss these findings in light of construal-level theory’s notion of abstraction. PMID:23482624

2018-05-01

Dental professionals have an opportunity to screen for substance use, provide targeted feedback based on patients' oral health, provide patient education, and refer for further assessment as needed. The aim of this study was to assess the impact on dental hygiene students of an interprofessional Screening, Brief Intervention, and Referral to Treatment (SBIRT) educational intervention with standardized patients as a tool for initiating discussions on alcohol and drug use with patients. Starting in 2015, dental hygiene students in two classes at the University of Pittsburgh participated with nursing students in one and a half hours of didactic instruction followed within a ten-week period by SBIRT simulation scenarios utilizing standardized patients, with subsequent debriefing of students by faculty. Students' attitudes were assessed before and after the didactic session and immediately after the SBIRT simulation, using the Alcohol and Alcohol Problems Perceptions Questionnaire and the Drug and Drug Problems Perceptions Questionnaire. All 67 dental hygiene students in the program at the time participated in the educational intervention and surveys. The results showed significant positive changes in role security, defined as the acceptance of SBIRT delivery as part of their role identity as dental hygienists, following the intervention. This study found that the IPE intervention with dental hygiene and nursing students improved the dental hygiene students' attitudes through using SBIRT.

Learning Abstract Physical Concepts from Experience: Design and Use of an RC Circuit

Science.gov (United States)

Parra, Alfredo; Ordenes, Jorge; de la Fuente, Milton

2018-05-01

Science learning for undergraduate students requires grasping a great number of theoretical concepts in a rather short time. In our experience, this is especially difficult when students are required to simultaneously use abstract concepts, mathematical reasoning, and graphical analysis, such as occurs when learning about RC circuits. We present a simple experimental model in this work that allows students to easily design, build, and analyze RC circuits, thus providing an opportunity to test personal ideas, build graphical descriptions, and explore the meaning of the respective mathematical models, ultimately gaining a better grasp of the concepts involved. The result suggests that the simple setup indeed helps untrained students to visualize the essential points of this kind of circuit.

Proofs and fundamentals a first course in abstract mathematics

CERN Document Server

Bloch, Ethan D

2003-01-01

In an effort to make advanced mathematics accessible to a wide variety of students, and to give even the most mathematically inclined students a solid basis upon which to build their continuing study of mathematics, there has been a tendency in recent years to introduce students to the for­ mulation and writing of rigorous mathematical proofs, and to teach topics such as sets, functions, relations and countability, in a "transition" course, rather than in traditional courses such as linear algebra. A transition course functions as a bridge between computational courses such as Calculus, and more theoretical courses such as linear algebra and abstract algebra. This text contains core topics that I believe any transition course should cover, as well as some optional material intended to give the instructor some flexibility in designing a course. The presentation is straightforward and focuses on the essentials, without being too elementary, too exces­ sively pedagogical, and too full to distractions. Some of ...

2013-01-01

Graphical abstract: - Highlights: • Stable suspension of yttria stabilized zirconia (YSZ) obtained in isopropanol medium. • Suspension chemistry and process parameters for electrophoretic deposition optimized. • Deposited film quality changed with iodine and water (dispersants) concentration. • Dense YSZ film (∼5 μm) fabricated onto non-conducting porous NiO-YSZ anode substrate. - Abstract: Suspensions of 8 mol% yttria stabilized zirconia (YSZ) particulates in isopropanol medium are prepared using acetylacetone, iodine and water as dispersants. The effect of dispersants concentration on suspension stability, particle size distribution, electrical conductivity and pH of the suspensions are studied in detail to optimize the suspension chemistry. Electrophoretic deposition (EPD) has been conducted to produce thin and dense YSZ electrolyte films. Deposition kinetics have been studied in depth and good quality films on conducting substrate are obtained at an applied voltage of 15 V for 3 min. YSZ films are also fabricated on non-conducting NiO-YSZ anode substrate using a steel plate on the reverse side of the substrate. Upon co-firing at 1400 °C for 6 h a dense YSZ film of thickness ∼5 μm is obtained. Such a half cell (anode + electrolyte) can be used to fabricate a solid oxide fuel cell on applying a suitable cathode layer

Lee, Gregory T

2018-01-01

This carefully written textbook offers a thorough introduction to abstract algebra, covering the fundamentals of groups, rings and fields. The first two chapters present preliminary topics such as properties of the integers and equivalence relations. The author then explores the first major algebraic structure, the group, progressing as far as the Sylow theorems and the classification of finite abelian groups. An introduction to ring theory follows, leading to a discussion of fields and polynomials that includes sections on splitting fields and the construction of finite fields. The final part contains applications to public key cryptography as well as classical straightedge and compass constructions. Explaining key topics at a gentle pace, this book is aimed at undergraduate students. It assumes no prior knowledge of the subject and contains over 500 exercises, half of which have detailed solutions provided.

Literature in the Abstract: Althusser and English Studies in England

Directory of Open Access Journals (Sweden)

David Margolies

1994-01-01

Full Text Available Althusser's work arrived just when the disintegrating liberal consensus was shaking the ivory towers of the university. Students protested the war in Vietnam as well as the policies of the university. Althusser offered an understanding of this corrupt world and its distorted self-image. These theories provided an exciting new totalization in which life had meaning and intellectuals, a vital role. In literary studies, students and lecturers assumed that works of literature were anti-scientific, preservers of the status quo, without genuine knowledge. Disillusioned, these students and lecturers condemned Literature as an institution and ignored the individual work. To stop teaching the dominant ideology, they found redemption through abstraction—general principles, abstract structures. Academics found it attractive to raise barricades in the mind, not the street. Althusserian ideas showed lecturers and students that what was thought to be a purely literary or factual matter of aesthetic appreciation was really ideological and political, but the arrogance of the Althusserians, who recognized no theory before Althusser and no value in empirical experience, offended potential allies.

Exploring students' patterns of reasoning

Science.gov (United States)

Matloob Haghanikar, Mojgan

As part of a collaborative study of the science preparation of elementary school teachers, we investigated the quality of students' reasoning and explored the relationship between sophistication of reasoning and the degree to which the courses were considered inquiry oriented. To probe students' reasoning, we developed open-ended written content questions with the distinguishing feature of applying recently learned concepts in a new context. We devised a protocol for developing written content questions that provided a common structure for probing and classifying students' sophistication level of reasoning. In designing our protocol, we considered several distinct criteria, and classified students' responses based on their performance for each criterion. First, we classified concepts into three types: Descriptive, Hypothetical, and Theoretical and categorized the abstraction levels of the responses in terms of the types of concepts and the inter-relationship between the concepts. Second, we devised a rubric based on Bloom's revised taxonomy with seven traits (both knowledge types and cognitive processes) and a defined set of criteria to evaluate each trait. Along with analyzing students' reasoning, we visited universities and observed the courses in which the students were enrolled. We used the Reformed Teaching Observation Protocol (RTOP) to rank the courses with respect to characteristics that are valued for the inquiry courses. We conducted logistic regression for a sample of 18courses with about 900 students and reported the results for performing logistic regression to estimate the relationship between traits of reasoning and RTOP score. In addition, we analyzed conceptual structure of students' responses, based on conceptual classification schemes, and clustered students' responses into six categories. We derived regression model, to estimate the relationship between the sophistication of the categories of conceptual structure and RTOP scores. However, the

Full Text Available Abstract Background Sexually transmitted Infections (STIs rank among the most important health issues for the people especially the young adults worldwide. Young people tend to engage in sexual activity at younger ages in the past decade than in the 1970s, and 1980s. Knowledge is an essential precursor of sexual risk reduction. A cross-sectional study was conducted in Pulau Pinang, Malaysia, to produce the baseline information about school students' awareness and perception about sexually transmitted Infections (STIs and their sexual activity to help establish control and education programmes. Methods Students from form 4 (aged between 15 to 16 years, form 5 (aged between 16 to 17 years and form 6 (aged between 18 to 20 years in their class rooms were approached and asked to complete self administered and anonymous pre-validated questionnaires. SPSS for windows version 13 was used to analyze the results statistically and results were presented in tabular form. Results Data was collected from 1139 students aged between 15 to 20 years, 10.6% of which claimed that they never heard about STIs. Sexual experience related significantly with gender, race, and education level. Approximately 12.6% claimed to have sexual experience of which 75.7% had their sexual debut at 15-19 years and 38.2% were having more than 3 partners. Sexual experience was found to be significantly associated with gender (p = 0.003, ethnicity (p = 0.001 and education level (p = 0.030. However, multiple partner behaviour was significantly associated only with gender (p = 0.010. Mean knowledge score was 11.60 ± 8.781 and knowledge level was significantly associated with religion (p = 0.005 education level (p = 0.000, course stream (p = 0.000, socioeconomic class (p = 0.000 and sexual experience (p = 0.022. Conclusions It was concluded that school students have moderate level of knowledge about STIs although they are sexually active. Interventions such as reinforcing the link

The aim of this study was to evaluate the publication rates of full-text articles after presentation of abstracts at a Turkish National Orthopaedics and Traumatology Congress, determine the time lag from the congress date to publication of full-text articles and assess the consistency between abstracts and the subsequent publications. All abstracts from the scientific program of the 20th Turkish National Orthopaedics and Traumatology Congress (2007) were identified and computerized PubMed searches were conducted to determine whether an abstract had been followed by publication of a full-text article and key features were compared to evaluate their consistency. The time lag to publication and the impact factors of the journals where the articles were published were noted. Of the 770 abstracts (264 oral, 506 poster presentations), 227 (29.5%) were followed by a full-text and 116 (44%) of the 264 oral and 111 (22%) of the 506 poster presentations were published. The mean time to publication was 14.9±16.075 (range: 33 to 55) months. Thirty-three (14.5%) were published prior to the presentation at the congress. The likelihood of publication decreased after the third year (26 of 227, 11.5%). A total of 182 (80.2%) articles showed inconsistencies with the abstract; 74 (32.6%) minor, 14 (6.2%) major, and 94 (41.4%) minor and major inconsistencies. The mean impact factor of the journals was 1.152±0.858. The vast majority of abstracts presented at this congress were not followed by publication of a full-text article. Additionally, frequent inconsistencies between the final published article and the original abstract indicated the inadequacy of quality of reporting in abstracts.

The use of Museum Based Science Centres to Expose Primary School Students in Developing Countries to Abstract and Complex Concepts of Nanoscience and Nanotechnology

Saidi, Trust; Sigauke, Esther

2017-10-01

Nanotechnology is an emerging technology, and it is regarded as the basis for the next industrial revolution. In developing countries, nanotechnology promises to solve everyday challenges, such as the provision of potable water, reliable energy sources and effective medication. However, there are several challenges in the exploitation of nanotechnology. One of the notable challenges is the lack of adequate knowledge about how materials behave at the nanoscale. As nanotechnology is relatively new, the current generation of scientists have not had the opportunity to learn the fundamentals of the technology at an early stage. Young students who are at the primary school level may follow the same trajectory if they are not exposed to the technology. There is a need to lay a strong foundation by introducing nanoscience and nanotechnology to students at the primary school level. It is during the early stages of child development that students master basic concepts for life long learning. Nevertheless, many primary school children, particularly those in developing countries are missing the chance of learning about nanoscience and nanotechnology because it is regarded as being abstract and complex. In this paper, we argue that despite the complexity of nanoscience and nanotechnology, science centres can be used as one of the platforms for exposing young students to the discipline. We use a case study of a museum-based science centre as an example to illustrate that young students can be exposed to nanoscience and nanotechnology using tactile and hands-on experience. The early engagement of primary school children with nanoscience and nanotechnology is important in raising the next generation of scientists who are firmly grounded in the discipline.

Full Text Available Abstract Background Bullying and sexual harassment of medical students by their teachers appears to be widespread phenomenon. However, nothing is published about its prevalence in conservative countries such as Saudi Arabia. This survey aims to ascertain the extent of these mistreatments among students in a Saudi medical school. Findings A cross-sectional questionnaire survey was conducted on a group of 542 clinical years’ medical students in a Saudi medical school to explore students' perceptions of their educational environment including exposure to different kinds of bullying. Bullying was defined as “a “persistent behaviour against a medical student that is intimidating, degrading, offensive or malicious and undermines the confidence and self- esteem of the recipient”. Results revealed that more than one quarter (28.0% of the surveyed students reported exposure to some sort of bullying during their clinical. Ninety percent of the reported insults were verbal, 6% sexual and 4% physical. Males were more exposed but difference was not statistically significant. Conclusions Bullying among Saudi medical students is an existing problem. A policy against bullying and harassment should be adopted in all of medical colleges to monitor this phenomenon and support students who have been bullied.

2015-03-01

Full Text Available This research investigated the history of Islamic abstract vegetal ornaments and sketched their evolution to understand their creation process and innovations. We studied these ornaments regionally to identify regional variations and classified them based on tastes of patrons. Meanwhile, we analysed the formal aspects of these ornaments, including their dimension, proportion, dominant colour, material, and techniques. In addition, the study conducted detailed observations of their characteristics, such as margins, apex, thickness of stem scrolls and vents, to define their constructive elements, aesthetical properties, and design principles that reveal date, region, and styles. This research not only provides a comprehensive guide to the evolution of Islamic abstract vegetal ornaments for architectural conservation projects but also serves as a reference for the comparative and critical analysis of contemporary Islamic-inspired ornaments.

The review was performed in order to determine the prevalence and symptomatology of ADHD in postsecondary students, to examine its effects on academic achievement, and discuss appropriate management. The prevalence of ADHD symptoms among postsecondary students ranges from 2% to 12%. Students with ADHD have lower grade point averages and are more likely to withdraw from courses, to indulge in risky behaviors, and to have other psychiatric comorbidities than their non-ADHD peers. Ensuring that students with ADHD receive appropriate support requires documented evidence of impairment to academic and day-to-day functioning. In adults with ADHD, stimulants improve concentration and attention, although improved academic productivity remains to be demonstrated. ADHD negatively impacts academic performance in students and increases the likelihood of drug and alcohol problems. Affected students may therefore benefit from disability support services, academic accommodations, and pharmacological treatment. Keywords: adults, academic performance, stimulants, treatment

Completeness of Lyapunov Abstraction

Directory of Open Access Journals (Sweden)

Rafael Wisniewski

2013-08-01

Full Text Available In this work, we continue our study on discrete abstractions of dynamical systems. To this end, we use a family of partitioning functions to generate an abstraction. The intersection of sub-level sets of the partitioning functions defines cells, which are regarded as discrete objects. The union of cells makes up the state space of the dynamical systems. Our construction gives rise to a combinatorial object - a timed automaton. We examine sound and complete abstractions. An abstraction is said to be sound when the flow of the time automata covers the flow lines of the dynamical systems. If the dynamics of the dynamical system and the time automaton are equivalent, the abstraction is complete. The commonly accepted paradigm for partitioning functions is that they ought to be transversal to the studied vector field. We show that there is no complete partitioning with transversal functions, even for particular dynamical systems whose critical sets are isolated critical points. Therefore, we allow the directional derivative along the vector field to be non-positive in this work. This considerably complicates the abstraction technique. For understanding dynamical systems, it is vital to study stable and unstable manifolds and their intersections. These objects appear naturally in this work. Indeed, we show that for an abstraction to be complete, the set of critical points of an abstraction function shall contain either the stable or unstable manifold of the dynamical system.

The effects of conducting authentic field-geology research on high school students' understanding of the nature of science, and their views of themselves as research scientists

Science.gov (United States)

Millette, Patricia M.

Authentic field geology research is a inquiry method that encourages students to interact more with their local environment, and by solving genuine puzzles, begin to increase their intuitive understanding of the nature and processes of science. The goal of the current study was to determine if conducting authentic field research and giving high school students the opportunity to present findings to adult audiences outside of the school setting 1) enhances students' understanding of the nature of science, and 2) affects students views of themselves as researchers. To accomplish this, ninth-grade students from a public school in northern New England engaged in a community-initiated glacial geology problem, completed a field research investigation, and presented their findings at several professional conferences. Following the completion of this student-centered field research, I investigated its effects by using a mixed methods approach consisting of qualitative and quantitative data from two sources. These included selected questions from an open-response survey (VNOS-c), and interviews that were conducted with fifteen of the students of different ages and genders. Findings show that conducting original field research seems to have a positive influence on these students' understanding of the NOS as well as the processes of science. Many of the students reported feelings of accomplishment, acceptance of responsibility for the investigation, a sense of their authentic contribution to the body of scientific knowledge in the world, and becoming scientists. This type of authentic field investigation is significant because recent reforms in earth-science education stress the importance of students learning about the nature and processes of scientific knowledge along with science content.

Abstract Datatypes in PVS

Science.gov (United States)

Owre, Sam; Shankar, Natarajan

1997-01-01

PVS (Prototype Verification System) is a general-purpose environment for developing specifications and proofs. This document deals primarily with the abstract datatype mechanism in PVS which generates theories containing axioms and definitions for a class of recursive datatypes. The concepts underlying the abstract datatype mechanism are illustrated using ordered binary trees as an example. Binary trees are described by a PVS abstract datatype that is parametric in its value type. The type of ordered binary trees is then presented as a subtype of binary trees where the ordering relation is also taken as a parameter. We define the operations of inserting an element into, and searching for an element in an ordered binary tree; the bulk of the report is devoted to PVS proofs of some useful properties of these operations. These proofs illustrate various approaches to proving properties of abstract datatype operations. They also describe the built-in capabilities of the PVS proof checker for simplifying abstract datatype expressions.

Undergraduate Students Seek Librarian Assistance Only After They Have Searched Independently Without Success

Full Text Available A Review of: Vinyard, M., Mullally, C., & Colvin, J.B. (2017. Why do students seek help in an age of DIY? Using a qualitative approach to look beyond statistics. Reference & User Services Quarterly, 56(4, 257-267. http://dx.doi.org/10.5860/rusq.56.4.257 Abstract Objective – To explore how undergraduate students look for information and the reasons these students seek assistance from a librarian. Design – Qualitative research. Setting – A university in Southern California. Subjects – 10 students were interviewed: 1 freshman, 1 sophomore, 5 juniors, and 3 seniors. Methods – Students who met with a librarian for longer than 20 minutes were invited to participate in the study, and interviews were conducted within six weeks of this interaction. Semi-structured interviews were scheduled for one hour blocks and were audio-recorded and transcribed afterward. Interview data was analyzed using applied thematic analysis. The researchers used NVivo to assist with the process of coding data. Main Results – Once all transcripts were coded, the researchers identified the following six themes related to how students look for information and the reasons they asked for assistance: how students research, personal perceptions of research skills, assumptions (students’ misperceptions about library services, motivation for asking for help, path to the librarian (how students contacted librarians and their reason for selecting a particular librarian, and experience working with a librarian. Conclusion – Overall, the research results demonstrate that students prefer to conduct research independently but will consult a librarian if they are not able to find what they need, if they find the research question especially challenging, or if they have spent an unreasonable amount of time conducting research. In-class library instruction, along with professor referrals are the most effective methods for encouraging students to seek out library assistance.

Reporting quality of conference abstracts on randomised controlled trials in gerontology and geriatrics: a cross-sectional investigation.

Science.gov (United States)

Mann, Eva; Meyer, Gabriele

2011-01-01

Without transparent reporting of how a randomised controlled trial was designed and conducted and of the methods used, its internal validity cannot be assessed by the reader. A congress abstract is often the only source providing information about a trial. In January 2008, an extended CONSORT statement on abstract reporting was published. Its impact has yet to be evaluated. Using a slightly modified CONSORT checklist comprising 17 items, we thus investigated the reporting quality of randomised controlled trials published in the book of abstracts presented at the World Congress of Geriatrics and Gerontology in Paris in July 2009. A total of n=4,416 abstracts was screened for inclusion; n=129 met the inclusion criteria. The overall quality of the abstracts was remarkably poor. The primary outcome was mentioned in 34/129 abstracts (26%), none of the abstracts reported on the procedure of random allocation of participants or clusters, 21/129 abstracts (16%) reported some kind of blinding, and the attrition rate was mentioned in only 12/129 abstracts (9%). The majority of abstracts fulfilled two items: description of intended intervention for each group (102/129; 79%) and general interpretation of results (107/129; 83%). Trial status was reported in all abstracts. Both journal editors and committees organising congresses are requested to define the use of the CONSORT statement as a prerequisite in their guidelines for authors and to instruct reviewers to conduct compliance checks. Medical associations should finally endorse the indispensability of the CONSORT statement and publish it in their journals. Otherwise the intended benefits cannot be fully generated.

WD1145+017 (Abstract)

Motta, M.

2017-12-01

(Abstract only) WD1145 is a 17th magnitude white dwarf star 570 light years away in Virgo that was discovered to have a disintegrating planetoid in close orbit by Andrew Vanderburg, a graduate student at Harvard CfA, while data mining the elucidate the nature of its rather bizarre transit light curves. I obtained multiple observations of WD1145 over the course of a year, and found a series of complex transit light curves that could only be interpreted as a ring complex or torus in close orbit around WD1145. Combined with data from other amateur astronomers, professional observations, and satellite data, it became clear that WD1145 has a small planetoid in close orbit at the Roche limit and is breaking apart, forming a ring of debris material that is then raining down on the white dwarf. The surface of the star is "polluted" by heavy metals, determined by spectroscopic data. Given that in the intense gravitational field of a white dwarf any heavy metals could not for long last on the surface, this confirms that we are tracking in real time the destruction of a small planet by its host star.

Invariant factors, Julia equivalences and the (abstract) Mandelbrot set

CERN Document Server

Keller, Karsten

2000-01-01

This book is mainly devoted to the combinatorics of quadratic holomorphic dynamics. The conceptual kernel is a self-contained abstract counterpart of connected quadratic Julia sets which is built on Thurston's concept of a quadratic invariant lamination and on symbolic descriptions of the angle-doubling map. The theory obtained is illustrated in the complex plane. It is used to give rigorous proofs of some well-known and some partially new statements on the structure of the Mandelbrot set. The text is intended for graduate students and researchers. Some elementary knowledge in topology and in functions of one complex variable is assumed.

Many learning resources can help students develop the problem-solving abilities and clinical skills required for diagnostic imaging. This study explored veterinary students' perceptions of the usefulness of a variety of learning resources. Perceived resource usefulness was measured for different levels of students and for academic versus clinical preparation. Third-year (n=139) and final (fifth) year (n=105) students and recent graduates (n=56) completed questionnaires on perceived usefulness of each resource. Resources were grouped for comparison: abstract/low complexity (e.g., notes, multimedia presentations), abstract/high complexity (e.g., Web-based and film case repositories), concrete/low complexity (e.g., large-group "clicker" workshops), and concrete/high complexity (e.g., small-group interpretation workshops). Lower-level students considered abstract/low-complexity resources more useful for academic preparation and concrete resources more useful for clinical preparation. Higher-level students/recent graduates also considered abstract/low-complexity resources more useful for academic preparation. For all levels, lecture notes were considered highly useful. Multimedia slideshows were an interactive complement to notes. The usefulness of a Web-based case repository was limited by accessibility problems and difficulty. Traditional abstract/low-complexity resources were considered useful for more levels and contexts than expected. Concrete/high-complexity resources need to better represent clinical practice to be considered more useful for clinical preparation.

Full-text publication of abstracts presented at European Orthodontic Society congresses.

Science.gov (United States)

Livas, Christos; Pandis, Nikolaos; Ren, Yijin

2014-10-01

Empirical evidence has indicated that only a subsample of studies conducted reach full-text publication and this phenomenon has become known as publication bias. A form of publication bias is the selectively delayed full publication of conference abstracts. The objective of this article was to examine the publication status of oral abstracts and poster-presentation abstracts, included in the scientific program of the 82nd and 83rd European Orthodontic Society (EOS) congresses, held in 2006 and 2007, and to identify factors associated with full-length publication. A systematic search of PubMed and Google Scholar databases was performed in April 2013 using author names and keywords from the abstract title to locate abstract and full-article publications. Information regarding mode of presentation, type of affiliation, geographical origin, statistical results, and publication details were collected and analyzed using univariable and multivariable logistic regression. Approximately 51 per cent of the EOS 2006 and 55 per cent of the EOS 2007 abstracts appeared in print more than 5 years post congress. A mean period of 1.32 years elapsed between conference and publication date. Mode of presentation (oral or poster), use of statistical analysis, and research subject area were significant predictors for publication success. Inherent discrepancies of abstract reporting, mainly related to presentation of preliminary results and incomplete description of methods, may be considered in analogous studies. On average 52.2 per cent of the abstracts presented at the two EOS conferences reached full publication. Abstracts presented orally, including statistical analysis, were more likely to get published. © The Author 2013. Published by Oxford University Press on behalf of the European Orthodontic Society.

Analogical scaffolding and the learning of abstract ideas in physics: An example from electromagnetic waves

Directory of Open Access Journals (Sweden)

Noah D. Finkelstein

2007-06-01

Full Text Available This paper describes a model of analogy, analogical scaffolding, which explains present and prior results of student learning with analogies. We build on prior models of representation, blending, and layering of ideas. Extending this model’s explanatory power, we propose ways in which the model can be applied to design a curriculum directed at teaching abstract ideas in physics using multiple, layered analogies. We report on a recent empirical study that motivates this model. Students taught about electromagnetic waves in a curriculum that builds on the model of analogical scaffolding posted substantially greater gains pre- to postinstruction than students taught using a more traditional (non-analogy-based tutorial (21% vs 7%.

Priatna, N.; Martadiputra, B. A. P.; Wibisono, Y.

2018-05-01

The development of science and technology requires reform in the utilization of various resources for mathematics teaching and learning process. One of the efforts that can be made is the implementation of GeoGebra-assisted Reciprocal Teaching strategy in mathematics instruction as an effective strategy in improving students’ cognitive, affective, and psychomotor abilities. This research is intended to implement GeoGebra-assisted Reciprocal Teaching strategy in improving abstraction ability, lateral thinking, and mathematical persistence of junior high school students. It employed quasi-experimental method with non-random pre-test and post-test control design. More specifically, it used the 2x3 factorial design, namely the learning factors that included GeoGebra-assisted Reciprocal Teaching and conventional teaching learning, and levels of early mathematical ability (high, middle, and low). The subjects in this research were the eighth grade students of junior high school, taken with purposive sampling. The results of this research show: Abstraction and lateral abilities of students who were taught with GeoGebra-assisted Reciprocal Teaching strategy were significantly higher than those of students who received conventional learning. Mathematical persistence of students taught with GeoGebra-assisted Reciprocal Teaching strategy was also significantly higher than of those taught with conventional learning.

Abstraction and art.

Science.gov (United States)

Gortais, Bernard

2003-07-29

In a given social context, artistic creation comprises a set of processes, which relate to the activity of the artist and the activity of the spectator. Through these processes we see and understand that the world is vaster than it is said to be. Artistic processes are mediated experiences that open up the world. A successful work of art expresses a reality beyond actual reality: it suggests an unknown world using the means and the signs of the known world. Artistic practices incorporate the means of creation developed by science and technology and change forms as they change. Artists and the public follow different processes of abstraction at different levels, in the definition of the means of creation, of representation and of perception of a work of art. This paper examines how the processes of abstraction are used within the framework of the visual arts and abstract painting, which appeared during a period of growing importance for the processes of abstraction in science and technology, at the beginning of the twentieth century. The development of digital platforms and new man-machine interfaces allow multimedia creations. This is performed under the constraint of phases of multidisciplinary conceptualization using generic representation languages, which tend to abolish traditional frontiers between the arts: visual arts, drama, dance and music.

Becoming a smart student

English abstract When teachers and students interact in everyday academic activities, some students are ascribed social roles as “smart”, which lead other students to contest these roles. Such struggles around what it means to be smart and which students come to be viewed as smart are a pertinent...... as smart and favoured by the teacher are at risk of being ostracized by peers, of encountering greater pressure for classroom performance and of suffering reduced learning opportunities. The study inspires teachers to create wiggle room for their students by becoming aware of the conventional definitions...

Metaphor: Bridging embodiment to abstraction.

Science.gov (United States)

Jamrozik, Anja; McQuire, Marguerite; Cardillo, Eileen R; Chatterjee, Anjan

2016-08-01

Embodied cognition accounts posit that concepts are grounded in our sensory and motor systems. An important challenge for these accounts is explaining how abstract concepts, which do not directly call upon sensory or motor information, can be informed by experience. We propose that metaphor is one important vehicle guiding the development and use of abstract concepts. Metaphors allow us to draw on concrete, familiar domains to acquire and reason about abstract concepts. Additionally, repeated metaphoric use drawing on particular aspects of concrete experience can result in the development of new abstract representations. These abstractions, which are derived from embodied experience but lack much of the sensorimotor information associated with it, can then be flexibly applied to understand new situations.

Effects of abstract and concrete antinuclear filmed presentations on participation in a petition campaign

International Nuclear Information System (INIS)

Gellis, J.

1989-01-01

The goal was to examine the effects of abstract and concrete anti-nuclear images and previous political activity on interest in the topic of nuclear war and participation in an anti-nuclear petition campaign. Subjects were 254 undergraduate students at Hofstra University in three political science classes, three psychology classes and three communication classes: 128 males and 126 females. They were assigned by class to one of three image conditions: concrete, abstract, or no image. After completing a questionnaire measuring their previous level of political activity, students in the concrete condition saw The Last Epidemic, a 30-minute video depicting the aftermath of a nuclear explosion. Subjects in the abstract condition saw Preventing Nuclear War-First Step, a 30 minute video conveying factual information about missile systems and the arms race. Subjects in the no-image condition were not exposed to a video and served as controls. They were asked to respond to a short questionnaire that elicited emotional and intellectual reactions to the topic of nuclear war. After viewing the video tape, subjects in the abstract and concrete conditions responded to a brief questionnaire that elicited emotional and intellectual reactions to the videos. Subjects in all three conditions were asked to provide their names addresses if they were interested in receiving more information on this topic. Subjects who provided their name and addresses were mailed, within 24-hours, a one page petition advocating an anti-nuclear position. Recipients were asked to sign the petition, gather as many signature as possible, and return the petition. Participation was measured by the number of signatures gathered. Data were analyzed by analyzes of variance. The type of image had no effect on either interest or participation in the petition campaign. A modest positive relationship was found between previous political activity and interest

Full Text Available Abstract: The purpose of this study was to find out whether the word mapping strategywas able to improve the students’ vocabulary mastery. The process of masteringis mainly affected by the worst thought of the vocational students who said that English as the most difficult subject to learn and was often tracked into boringcondition since theywere not involved in the process of learning. Thisstudy was conducted by using classroom action research in two cycles and each cycleconsisted of four meetings. The subject of the research was the third grade of Accounting Department at State Vocational School 1 Pamekasan whichconsisted of 34 students. The research was carried out for one month.Theinstruments used to obtained primary data and the secondary data were vocabulary test, the students’ observation sheets, and questionnaire of the respondent.The result of test in preliminary until the test in cycle two showed that there was the improvement of the number of students who passed the test. Hopefully, this outcome will certainly be useful for both teachers and students in which its harmony will give the progress for learning English,especially vocabulary mastery.

2004-01-01

The primary purpose of this model report is to develop abstractions for the response of engineered barrier system (EBS) components to seismic hazards at a geologic repository at Yucca Mountain, Nevada, and to define the methodology for using these abstractions in a seismic scenario class for the Total System Performance Assessment - License Application (TSPA-LA). A secondary purpose of this model report is to provide information for criticality studies related to seismic hazards. The seismic hazards addressed herein are vibratory ground motion, fault displacement, and rockfall due to ground motion. The EBS components are the drip shield, the waste package, and the fuel cladding. The requirements for development of the abstractions and the associated algorithms for the seismic scenario class are defined in ''Technical Work Plan For: Regulatory Integration Modeling of Drift Degradation, Waste Package and Drip Shield Vibratory Motion and Seismic Consequences'' (BSC 2004 [DIRS 171520]). The development of these abstractions will provide a more complete representation of flow into and transport from the EBS under disruptive events. The results from this development will also address portions of integrated subissue ENG2, Mechanical Disruption of Engineered Barriers, including the acceptance criteria for this subissue defined in Section 2.2.1.3.2.3 of the ''Yucca Mountain Review Plan, Final Report'' (NRC 2003 [DIRS 163274])

We present an effective algorithm for the automatic construction of finite modal transition systems as abstractions of potentially infinite concurrent processes. Modal transition systems are recognized as valuable abstractions for model checking because they allow for the validation as well...... as refutation of safety and liveness properties. However, the algorithmic construction of finite abstractions from potentially infinite concurrent processes is a missing link that prevents their more widespread usage for model checking of concurrent systems. Our algorithm is a worklist algorithm using concepts...... from abstract interpretation and operating upon mappings from sets to intervals in order to express simultaneous over- and underapprox-imations of the multisets of process actions available in a particular state. We obtain a finite abstraction that is 3-valued in both states and transitions...

Although many students conduct research with faculty in organized summer programs or as part of their course work or their degree work, they often face barriers to traveling to present that research, especially at national or international conferences. This is especially true for students who are members of underrepresented minority populations and students studying outside of the United States. A new and exciting opportunity for undergraduate as well as graduate students to showcase their work is now available. AGU piloted three opportunities for an undergraduate and graduate virtual poster showcase in the fall of 2015. Student participants were recruited from a diverse array of groups including minority-serving organizations, two-year colleges, and internship programs at federal agencies and national laboratories. Students uploaded an abstract, poster, and short video explain their research, and then participated in Q&A sessions with peers as well as expert judges. This presentation will share characteristics of participating groups, lessons learned from this new program, and preliminary evaluation findings as well as plans for the future.

Typesafe Abstractions for Tensor Operations

OpenAIRE

Chen, Tongfei

2017-01-01

We propose a typesafe abstraction to tensors (i.e. multidimensional arrays) exploiting the type-level programming capabilities of Scala through heterogeneous lists (HList), and showcase typesafe abstractions of common tensor operations and various neural layers such as convolution or recurrent neural networks. This abstraction could lay the foundation of future typesafe deep learning frameworks that runs on Scala/JVM.

Inventory Abstraction

The purpose of the inventory abstraction as directed by the development plan (CRWMS M and O 1999b) is to: (1) Interpret the results of a series of relative dose calculations (CRWMS M and O 1999c, 1999d). (2) Recommend, including a basis thereof, a set of radionuclides that should be modeled in the Total System Performance Assessment in Support of the Site Recommendation (TSPA-SR) and the Total System Performance Assessment in Support of the Final Environmental Impact Statement (TSPA-FEIS). (3) Provide initial radionuclide inventories for the TSPA-SR and TSPA-FEIS models. (4) Answer the U.S. Nuclear Regulatory Commission (NRC)'s Issue Resolution Status Report ''Key Technical Issue: Container Life and Source Term'' (CLST IRSR) (NRC 1999) key technical issue (KTI): ''The rate at which radionuclides in SNF [Spent Nuclear Fuel] are released from the EBS [Engineered Barrier System] through the oxidation and dissolution of spent fuel'' (Subissue 3). The scope of the radionuclide screening analysis encompasses the period from 100 years to 10,000 years after the potential repository at Yucca Mountain is sealed for scenarios involving the breach of a waste package and subsequent degradation of the waste form as required for the TSPA-SR calculations. By extending the time period considered to one million years after repository closure, recommendations are made for the TSPA-FEIS. The waste forms included in the inventory abstraction are Commercial Spent Nuclear Fuel (CSNF), DOE Spent Nuclear Fuel (DSNF), High-Level Waste (HLW), naval Spent Nuclear Fuel (SNF), and U.S. Department of Energy (DOE) plutonium waste. The intended use of this analysis is in TSPA-SR and TSPA-FEIS. Based on the recommendations made here, models for release, transport, and possibly exposure will be developed for the isotopes that would be the highest contributors to the dose given a release to the accessible environment. The inventory abstraction is important in assessing system performance because

OBJECTIVE. To implement and assess a task-based learning exercise that prompts pharmacy students to integrate their understanding of different disciplines. DESIGN. Master of pharmacy (MPharm degree) students were provided with simulated information from several preclinical science and from clinical trials and asked to synthesize this into a marketing authorization application for a new drug. Students made a link to pharmacy practice by creating an advice leaflet for pharmacists. ASSESSMENT. Students' ability to integrate information from different disciplines was evaluated by oral examination. In 2 successive academic years, 96% and 82% of students demonstrated an integrated understanding of their proposed new drug. Students indicated in a survey that their understanding of the links between different subjects improved. CONCLUSION. Simulated drug discovery provides a learning environment that emphasizes the connectivity of the preclinical sciences with each other and the practice of pharmacy.

Burnout is a growing epidemic among professional healthcare students. Unaddressed burnout has been shown to have psychological and performance related detriments. The purpose of this scoping literature review was to investigate the prevalence of burnout and its effects on the psychological, professional, empathetic ability, and academic acuity of graduate healthcare students. Inclusion criteria included English language papers published within the last 10 years and subjects in graduate healthcare professional programs. This search encompassed 8,214 articles. After title and abstract screening, 127 articles remained and were sorted into five domains of interest: etiology, professionalism, mental health, empathy, and academic performance. After duplicates were removed, 27 articles remained for the scoping review. Graduate level healthcare students had higher levels of burnout than age matched peers and the general population. The high prevalence of burnout within graduate healthcare students can have an effect on their mental health, empathy, and professional conduct. Understanding the occurrence and effects of burnout within graduate healthcare programs allows faculty and administration to plan curriculum, and provide information to students to understand, recognize, and create opportunities to decrease burnout in order to create long lasting quality clinicians.

2017-12-01

(Abstract only) The Boyce Research Initiatives and Education Foundation (BRIEF) is providing semester-long, hands-on, astronomy research experiences for students of all ages that results in their publishing peer-reviewed papers. The course in astronomy and double star research has evolved from a face-to-face learning experience with two instructors to an online hybrid course that simultaneously supports classroom instruction at a variety of schools in the San Diego area. Currently, there are over 65 students enrolled in three community colleges, seven high schools, and one university as well as individual adult learners. Instructional experience, courseware, and supporting systems were developed and refined through experience gained in classroom settings from 2014 through 2016. Topics of instruction include Kepler's Laws, basic astrometry, properties of light, CCD imaging, use of filters for varying stellar spectral types, and how to perform research, scientific writing, and proposal preparation. Volunteer instructors were trained by taking the course and producing their own research papers. An expanded program was launched in the fall semester of 2016. Twelve papers from seven schools were produced; eight have been accepted for publication by the Journal of Double Star Observations (JDSO) and the remainder are in peer review. Three additional papers have been accepted by the JDSO and two more are in process papers. Three college professors and five advanced amateur astronomers are now qualified volunteer instructors. Supporting tools are provided by a BRIEF server and other online services. The server-based tools range from Microsoft Office and planetarium software to top-notch imaging programs and computational software for data reduction for each student team. Observations are performed by robotic telescopes worldwide supported by BRIEF. With this success, student demand has increased significantly. Many of the graduates of the first semester course wanted to

Full Text Available Abstract Background The Federal Democratic Republic of Nepal is a developing country in South Asia with a population of 29.8 million. In September 2011, there were 18 medical schools with 14 being in the private sector. KIST Medical College is a private school in Lalitpur district. The present study was conducted to obtain information on student perceptions about working in rural Nepal after graduation. Methods The study was conducted among first- and second-year undergraduate medical students using a semi-structured questionnaire developed by the authors using inputs from the literature and their experiences of teaching medical students. Year of study, gender, method of financing of medical education, place of family residence and occupation of parents were noted. Participant responses were analysed, grouped together and the number of respondents stating a particular response was noted. Results Of the 200 students, 185 (92.5% participated with 95 being from the first year and 90 from the second. Most students were self-financing and from urban areas. Regarding the question of working in rural Nepal after graduation, 134 (72.4% said they will work after their undergraduate course. Students preferred to work in the government or nongovernmental sector. Student felt doctors are reluctant to serve in rural Nepal due to inadequate facilities, low salary, less security, problems with their professional development, less equipment in health centres, decreased contact with family and difficulties in communicating with an illiterate, rural population. About 43% of respondents felt medical education does not adequately prepare them for rural service. Repeated rural exposure, postings in rural hospitals and health centres, and training students to diagnose and treat illness with less technology were suggested. The median monthly salary expected was 60 000 Nepalese rupees (US$ 820 and was significantly higher among first-year students. Conclusions The

One time-consuming aspect of conducting systematic reviews is the task of sifting through abstracts to identify relevant studies. One promising approach for reducing this burden uses text mining technology to identify those abstracts that are potentially most relevant for a project, allowing those abstracts to be screened first. To examine the effectiveness of the text mining functionality of the abstract screening tool Rayyan. User experiences were collected. Rayyan was used to screen abstracts for 6 reviews in 2015. After screening 25%, 50%, and 75% of the abstracts, the screeners logged the relevant references identified. A survey was sent to users. After screening half of the search result with Rayyan, 86% to 99% of the references deemed relevant to the study were identified. Of those studies included in the final reports, 96% to 100% were already identified in the first half of the screening process. Users rated Rayyan 4.5 out of 5. The text mining function in Rayyan successfully helped reviewers identify relevant studies early in the screening process. Copyright © 2017 John Wiley & Sons, Ltd.

EBS Radionuclide Transport Abstraction

International Nuclear Information System (INIS)

Schreiner, R.

2001-01-01

The purpose of this work is to develop the Engineered Barrier System (EBS) radionuclide transport abstraction model, as directed by a written development plan (CRWMS M and O 1999a). This abstraction is the conceptual model that will be used to determine the rate of release of radionuclides from the EBS to the unsaturated zone (UZ) in the total system performance assessment-license application (TSPA-LA). In particular, this model will be used to quantify the time-dependent radionuclide releases from a failed waste package (WP) and their subsequent transport through the EBS to the emplacement drift wall/UZ interface. The development of this conceptual model will allow Performance Assessment Operations (PAO) and its Engineered Barrier Performance Department to provide a more detailed and complete EBS flow and transport abstraction. The results from this conceptual model will allow PA0 to address portions of the key technical issues (KTIs) presented in three NRC Issue Resolution Status Reports (IRSRs): (1) the Evolution of the Near-Field Environment (ENFE), Revision 2 (NRC 1999a), (2) the Container Life and Source Term (CLST), Revision 2 (NRC 1999b), and (3) the Thermal Effects on Flow (TEF), Revision 1 (NRC 1998). The conceptual model for flow and transport in the EBS will be referred to as the ''EBS RT Abstraction'' in this analysis/modeling report (AMR). The scope of this abstraction and report is limited to flow and transport processes. More specifically, this AMR does not discuss elements of the TSPA-SR and TSPA-LA that relate to the EBS but are discussed in other AMRs. These elements include corrosion processes, radionuclide solubility limits, waste form dissolution rates and concentrations of colloidal particles that are generally represented as boundary conditions or input parameters for the EBS RT Abstraction. In effect, this AMR provides the algorithms for transporting radionuclides using the flow geometry and radionuclide concentrations determined by other

Full Text Available The abstraction of data from medical records is a widespread practice in epidemiological research. However, studies using this means of data collection rarely report reliability. Within the Transition after Childhood Cancer Study (TaCC which is based on a medical record abstraction, we conducted a second independent abstraction of data with the aim to assess a intra-rater reliability of one rater at two time points; b the possible learning effects between these two time points compared to a gold-standard; and c inter-rater reliability.Within the TaCC study we conducted a systematic medical record abstraction in the 9 Swiss clinics with pediatric oncology wards. In a second phase we selected a subsample of medical records in 3 clinics to conduct a second independent abstraction. We then assessed intra-rater reliability at two time points, the learning effect over time (comparing each rater at two time-points with a gold-standard and the inter-rater reliability of a selected number of variables. We calculated percentage agreement and Cohen's kappa.For the assessment of the intra-rater reliability we included 154 records (80 for rater 1; 74 for rater 2. For the inter-rater reliability we could include 70 records. Intra-rater reliability was substantial to excellent (Cohen's kappa 0-6-0.8 with an observed percentage agreement of 75%-95%. In all variables learning effects were observed. Inter-rater reliability was substantial to excellent (Cohen's kappa 0.70-0.83 with high agreement ranging from 86% to 100%.Our study showed that data abstracted from medical records are reliable. Investigating intra-rater and inter-rater reliability can give confidence to draw conclusions from the abstracted data and increase data quality by minimizing systematic errors.

Heat Conduction of Air in Nano Spacing

Directory of Open Access Journals (Sweden)

Zhang Yao-Zhong

2009-01-01

Full Text Available Abstract The scale effect of heat conduction of air in nano spacing (NS is very important for nanodevices to improve their life and efficiency. By constructing a special technique, the changes of heat conduction of air were studied by means of measuring the heat conduction with heat conduction instrument in NS between the hot plate and the cooling plate. Carbon nanotubes were used to produce the nano spacing. The results show that when the spacing is small down to nanometer scale, heat conduction plays a prominent role in NS. It was found that the thickness of air is a non-linear parameter for demarcating the heat conduction of air in NS and the rate of heat conduction in unit area could be regard as a typical parameter for the heat conduction characterization at nanometer scale.

Full Text Available ABSTRACT:Drug abuse is the willful misuse of either licit or illicit drugs for the purpose of recreation, perceived necessity or convenience. Drug abuse is a more intense and often willful misuse of drugs often to the point of addiction. In the eastern world the incidence shows a decline or a static pattern but the number of drug addicts is still enormous.. The major drug of abuse are heroin and marijuana but designer drugs are shown to be on the increase. The aim of the study is to determine the ratio of the drug abuse in student. For this purpose we selected different institutions including “the university of Lahore”, “Forman Christian college”(private sector and Punjab university(Govt sector and conducted survey in 500 student. High proportion of students was found abusing drugs. From this study, we came across multiple factors which are the main cause of drug abuse in medical student including depression, anxiety, schizophrenia, as well as personality disorder like antisocial personality disorder. The most commonly abused drugs include stimulants, opioids, and benzodiazepines, antihistamines. Although survey have indicated high rate of illicit and prescription drugs misuse among college students, few have assessed the negative consequences, personel concerns, or interest in intervention for drugs use. Drug abuse although regarded as a personality disorder, may also be seen as worldwide epidemic with evolutionary genetic, physiology and environmental influences Controlling and affecting human behavior. Globally, the use has reached all time high. The study showed males are more drug abusers as compared to females. The drug abuse ratio in students of private sector is more as compared to Govt sector.

Knowledge acquisition for temporal abstraction.

Science.gov (United States)

Stein, A; Musen, M A; Shahar, Y

1996-01-01

Temporal abstraction is the task of detecting relevant patterns in data over time. The knowledge-based temporal-abstraction method uses knowledge about a clinical domain's contexts, external events, and parameters to create meaningful interval-based abstractions from raw time-stamped clinical data. In this paper, we describe the acquisition and maintenance of domain-specific temporal-abstraction knowledge. Using the PROTEGE-II framework, we have designed a graphical tool for acquiring temporal knowledge directly from expert physicians, maintaining the knowledge in a sharable form, and converting the knowledge into a suitable format for use by an appropriate problem-solving method. In initial tests, the tool offered significant gains in our ability to rapidly acquire temporal knowledge and to use that knowledge to perform automated temporal reasoning.

The themes, institutions, and people of medical education research 1988-2010: content analysis of abstracts from six journals.

Science.gov (United States)

Rotgans, Jerome I

2012-10-01

The present study aimed at providing an overview of the most common themes of research into medical education. Changes in frequency of occurrence of these themes over time and differences between US and European journals were studied. The most productive institutions and researchers in the field were examined. A content analysis was carried out on 10,168 abstracts extracted from the six most influential journals in medical education published since 1988. Twenty-nine major themes were identified, of which student assessment, clinical and communication skills, clinical clerkships, and problem-based learning were the most prominent ones. Some of these themes, such as multiple-choice examinations or computer-assisted instruction seemed to have had their day, whereas other topics, such as the study of clinical clerkships, clinical reasoning, and scholarship in education were on their way up. Medical education research turned out to be a thoroughly international affair to which both US and European research centers contribute. The medical education literature shows an overwhelming emphasis on the preparation of medical students for professional practice. Moreover, the emphasis is very much on the individual student; most research seems to have been conducted with a psychological perspective in mind. It is argued that medical education research would profit from broadening its scope, including sociological, economical, ecological, and system perspectives. These perspectives might bring answers to new questions relevant to the quality of medical education. It is suggested that medical education is in need of moving beyond the conventional effectiveness-driven research approach to a more theory- and discovery-driven approach.

Professional values are abstract and general behavioral principles that provide basic standards to judge aims and actions, and these principles are formed by strong emotional loyalty of members of the profession. Research was conducted to compare the career choice and professional values of nursing students at two universities in the upper Midwest of the United States and in the middle of Turkey. A descriptive and comparative design was used. The participants of the study were comprised nursing students from a university in the upper Midwest of United States and a university in the middle of Turkey. The sample consisted of 728 students in all grades. Data were collected by a questionnaire, The Nurses Professional Values Scale-Revised and Vocational Choices in Entering Nursing Scale. Number, percentage distribution, mean, standard deviation, t test, and one-way variance analysis were used in the analysis of data. Ethical considerations: Ethical approval was obtained from the Ethics Commission. Informed consent was received from the students. The students' mean age for American students was 24.3 ± 5.6 years, while the mean age for Turkish students was 19.8 ± 1.7 years. Mean score of American students on The Vocational Congruency (a subgroup of the Vocational Choices in Entering Nursing Scale) was 38.5 ± 5.9 and Turkish students was 29.6 ± 8.9 (p Values Scale-Revised was 109.2 ± 12.3 and that of Turkish students was 101.6 ± 17.0. This study concluded that the majority of nursing students had high professional values, and when students' scores were compared, American students had higher professional values, and in career choice, they considered primarily fitness of the profession to themselves and their goals, while Turkish students primarily thought of their living conditions.

Is the Abstract a Mere Teaser? Evaluating Generosity of Article Abstracts in the Environmental Sciences

Directory of Open Access Journals (Sweden)

Liana Ermakova

2018-05-01

Full Text Available An abstract is not only a mirror of the full article; it also aims to draw attention to the most important information of the document it summarizes. Many studies have compared abstracts with full texts for their informativeness. In contrast to previous studies, we propose to investigate this relation based not only on the amount of information given by the abstract but also on its importance. The main objective of this paper is to introduce a new metric called GEM to measure the “generosity” or representativeness of an abstract. Schematically speaking, a generous abstract should have the best possible score of similarity for the sections important to the reader. Based on a questionnaire gathering information from 630 researchers, we were able to weight sections according to their importance. In our approach, seven sections were first automatically detected in the full text. The accuracy of this classification into sections was above 80% compared with a dataset of documents where sentences were assigned to sections by experts. Second, each section was weighted according to the questionnaire results. The GEM score was then calculated as a sum of weights of sections in the full text corresponding to sentences in the abstract normalized over the total sum of weights of sections in the full text. The correlation between GEM score and the mean of the scores assigned by annotators was higher than the correlation between scores from different experts. As a case study, the GEM score was calculated for 36,237 articles in environmental sciences (1930–2013 retrieved from the French ISTEX database. The main result was that GEM score has increased over time. Moreover, this trend depends on subject area and publisher. No correlation was found between GEM score and citation rate or open access status of articles. We conclude that abstracts are more generous in recent publications and cannot be considered as mere teasers. This research should be pursued

Journalistic Ethics and Standards in the Spanish Constitution and National Codes of Conduct from the Perspective of Andalusian Journalism Students

2013-12-01

Full Text Available This paper focuses on the opinion held by journalism students of the Faculty of Communication of Seville University about the ethical standards set out in the Spanish Constitution (Article 20.1.d and the country’s codes of conduct. The aim of this paper is to identify the ethical system of values of today’s university students, who have not yet been “contaminated” by the profession and on whom the future of journalism in Spain will ultimately depend. Although the results show that journalism students (both 1st year students and those in their final year have embraced a fairly solid ethical system of values, they nevertheless believe that the strong influence that economic and political powers currently exert on Spanish media corporations makes it impossible for journalists to cultivate their own work ethic, consequently obliging them to conform to the “unscrupulous” demands of their bosses. Faced with this reality, the authors reflect on the need to reinforce ethical values in the lecture hall as a way of curbing, as soon as possible, the deterioration of journalism that has been detected in Spain.

Robust domain decomposition preconditioners for abstract symmetric positive definite bilinear forms

KAUST Repository

Efendiev, Yalchin

2012-02-22

An abstract framework for constructing stable decompositions of the spaces corresponding to general symmetric positive definite problems into "local" subspaces and a global "coarse" space is developed. Particular applications of this abstract framework include practically important problems in porous media applications such as: the scalar elliptic (pressure) equation and the stream function formulation of its mixed form, Stokes\\' and Brinkman\\'s equations. The constant in the corresponding abstract energy estimate is shown to be robust with respect to mesh parameters as well as the contrast, which is defined as the ratio of high and low values of the conductivity (or permeability). The derived stable decomposition allows to construct additive overlapping Schwarz iterative methods with condition numbers uniformly bounded with respect to the contrast and mesh parameters. The coarse spaces are obtained by patching together the eigenfunctions corresponding to the smallest eigenvalues of certain local problems. A detailed analysis of the abstract setting is provided. The proposed decomposition builds on a method of Galvis and Efendiev [Multiscale Model. Simul. 8 (2010) 1461-1483] developed for second order scalar elliptic problems with high contrast. Applications to the finite element discretizations of the second order elliptic problem in Galerkin and mixed formulation, the Stokes equations, and Brinkman\\'s problem are presented. A number of numerical experiments for these problems in two spatial dimensions are provided. © EDP Sciences, SMAI, 2012.

Full Text Available Abstract Background In medical education, feedback from students' is essential in course evaluation and development. Students at Faculty of Medicine, University of Colombo, Sri Lanka complete a five year medical curriculum comprising of five different streams. We aimed to evaluate the five year medical curriculum at the Faculty of Medicine, University of Colombo, Sri Lanka. Methods A qualitative research was conducted among recent graduates of the faculty. Students' opinions on strengths and weaknesses of the curriculum were collected via questionnaires, which were analysed and classified into common themes. A focus group discussion (FGD based on these themes was conducted among two student groups, each comprising of a facilitator, two observers and nine students selected as a representative sample from questionnaire respondents. FGDs were conducted using a semi-structured set of open-ended questions to guide participants and maintain consistency between groups. The FGD evaluated the reasons behind students' perceptions, attitudes, emotions and perceived solution. Verbal and non-verbal responses were transcribed and analysed. Results Questionnaire response rate was 82% (153/186. Students highlighted 68 and 135 different responses on strengths and weaknesses respectively. After analysis of both questionnaire and FGD results the following themes emerged: a well organized module system, increased frequency of assessments, a good variety in clinical appointments, lack of specific objectives and assessments at clinical appointments, community and behavioural sciences streams beneficial but too much time allocation, lengthy duration of course, inadequate knowledge provided on pharmacology and pathology. Conclusion We demonstrate how a brief qualitative method could be efficiently used to evaluate a curriculum spanning a considerable length of time. This method provided an insight into the students' attitudes and perceptions of the present faculty

2013-07-01

Full Text Available Abstract: This paper critically describes the main challenges English language teachers face in teaching in Indonesia. The subjects of the research were students and English teachers in twelve randomly selected junior high schools in government and private schools in five districts in Yogyakarta Province. A survey schedule, interviews with English language teachers, focus group discussions with students and class observation were used to gather the data. The results show that students’ motivation is more of an instrumental motivation, due to the requirements of the mandated national examination though English now is a global language and the 2006 curriculum targets communicative competence. On the other hand, the data indicated that teachers found English difficult to use in class. The classroom instruction was conducted mostly in the low variety of Bahasa Indonesia and in Javanese. The teachers claimed that it was due to students’ low motivation; in fact, the students’ eagerness to listen to the teachers as the models of English language expressions was good. Teachers need to motivate students to learn English by improving their teaching techniques as well as their speaking competence in class to achieve student integrative motivation as English is valuable for them.

Full Text Available Abstract Background Cross-year peer tutoring (CYPT of medical students is recognized as an effective learning tool. The aim of this study is to investigate the non-inferiority of the objective outcome of medical interview training with CYPT compared with the results of faculty-led training (FLT, and to explore qualitatively the educational benefits of CYPT. Methods We conducted a convergent mixed methods study including a randomized controlled non-inferiority trial and two focus groups. For the CYPT group, teaching was led by six student tutors from year 5. In the FLT group, students were taught by six physicians. Focus groups for student learners (four tutees and student teachers (six tutors were conducted following the training session. Results One hundred sixteen students agreed to participate. The OSCE scores of the CYPT group and FLT group were 91.4 and 91.2, respectively. The difference in the mean score was 0.2 with a 95% CI of −1.8 to 2.2 within the predetermined non-inferiority margin of 3.0. By analyzing the focus groups, we extracted 13 subordinate concepts and formed three categories including ‘Benefits of CYPT’, ‘Reflections of tutees and tutors’ and ‘Comparison with faculty’, which affected the interactions among tutees, tutors, and faculty. Conclusions CYPT is effective for teaching communication skills to medical students and for enhancing reflective learning among both tutors and tutees.

Repetitive thoughts can be divided in two modes: abstract/analytic (decontextualized and dysfunctional) and concrete/experiential (problem-focused and adaptive). They constitute a transdiagnostic process involved in many psychopathological states but have received little attention in schizophrenia, as earlier studies only indexed increased ruminations (related to dysfunctional repetitive thoughts) without jointly exploring both modes. This study explored the two repetitive thinking modes, beyond ruminations, to determine their imbalance in schizophrenia. Thirty stabilized patients with schizophrenia and 30 matched controls completed the Repetitive Response Scale and the Mini Cambridge-Exeter Repetitive Thought Scale, both measuring repetitive thinking modes. Complementary measures related to schizophrenic symptomatology, depression and anxiety were also conducted. Compared to controls, patients with schizophrenia presented an imbalance between repetitive thinking modes, with increased abstract/analytic and reduced concrete/experiential thoughts, even after controlling for comorbidities. Schizophrenia is associated with stronger dysfunctional repetitive thoughts (i.e. abstract thinking) and impaired ability to efficiently use repetitive thinking for current problem-solving (i.e. concrete thinking). This imbalance confirms the double-faced nature of repetitive thinking modes, whose influence on schizophrenia's symptomatology should be further investigated. The present results also claim for evaluating these processes in clinical settings and for rehabilitating the balance between opposite repetitive thinking modes. Copyright © 2017 Elsevier Inc.

‘Abstract Endangerment’, Two Harm Principles, and Two Routes to Criminalisation

Directory of Open Access Journals (Sweden)

R.A. Duff

2015-12-01

Full Text Available We need to distinguish, as theorists too often fail to distinguish, two distinct harm principles. One, the Harmful Conduct Principle, concerns the criminalisation of conduct that is itself harmful or dangerous: that principle cannot explain how we can have good reason to create offences of so-called ‘abstract endangerment’, of which many road traffic offences are good examples. We can explain such offences as those by appeal to a different harm principle, the Harm Prevention Principle. That principle, however, is a principle not of criminalisation, but of regulation: it gives us reason to regulate conduct if doing so will efficiently prevent harm, without imposing undue burdens on those whose conduct is regulated. We then have reason to criminalise violations of such regulations, not because such violations are always harmful, but if and because they are wrongful. This distinction, between two kinds of principle and two possible routes towards criminalisation, can be drawn whatever goals or values we posit as our starting points.

Graphical abstract: - Highlights: • Composite colloidal particles combining conducting polymer and metal have been prepared. • Conducting colloids are suitable for printing applications. • Polypyrrole/silver colloids are prepared in a single reaction step. • The conductivity control is discussed and still needs improvement. - Abstract: The oxidation of pyrrole with silver nitrate in the presence of suitable water-soluble polymers yields composite polypyrrole–silver colloids. The polypyrrole–silver nanoparticles stabilized with poly(N-vinylpyrrolidone) have a typical size around 350 nm and polydispersity index 0.20, i.e. a moderate polydispersity in size. Similar results have been obtained with poly(vinyl alcohol) as stabilizer. The effect of stabilizer concentration on the particle size is marginal. In the present study, several types of stabilizers have been tested in addition to currently used poly(N-vinylpyrrolidone). Transmission electron microscopy and optical microscopy revealed the gemini morphology of polypyrrole and silver colloidal nanoparticles and confirmed their size and size-distribution determined by dynamic light scattering. The use of colloidal dispersions provides an efficient tool for the UV–vis and FT Raman spectroscopic characterization of polypyrrole, including the transition between polypyrrole salt and corresponding polypyrrole base. The dispersions were used for the preparation of coatings on polyethylene terephthalate foils, and the properties for polypyrrole–silver composites have been compared with those produced from polypyrrole colloids alone

Full Text Available Customer satisfaction has long been recognized as a central concept of all business activities. Satisfaction can serve as an indicator of success of the company, both in the past and present, as well as an indicator of future performance. High quality service to students is a prerequisite of maintaining competitiveness in the market of higher education. A relationship that is created between the expectations of students and their satisfaction with the quality of service that provides educational institution plays an important role in shaping the reputation of academic institutions. Academic institutions are becoming aware of the importance of student satisfaction, because satisfaction positively influences their decision to continue their education at this institution, and the positive word of mouth that will attract prospective students. Satisfaction will affect student motivation, and therefore their performance. This paper provides insight into the marketing aspects of customer satisfaction, primarily insight into the satisfaction of students in the educational sector. The aim is to establish the influence of satisfaction various factors related to the university and higher education to the satisfaction of student life, and does student life satisfaction affect the overall happiness and student performance. The research was conducted on the student population of the University of Split, on a sample of 191 respondents. The research was conducted with the help of online survey questionnaire. The claim that student’s satisfactions with housing affect the satisfaction with the quality of student life is rejected. The results confirmed that the student’s satisfaction with university contents, university bodies and services, teaching, teaching methods and academic reputation affects the satisfaction of student life and student life satisfaction affect the student performance.

Analysis of complex networks using aggressive abstraction.

Energy Technology Data Exchange (ETDEWEB)

Colbaugh, Richard; Glass, Kristin.; Willard, Gerald

2008-10-01

This paper presents a new methodology for analyzing complex networks in which the network of interest is first abstracted to a much simpler (but equivalent) representation, the required analysis is performed using the abstraction, and analytic conclusions are then mapped back to the original network and interpreted there. We begin by identifying a broad and important class of complex networks which admit abstractions that are simultaneously dramatically simplifying and property preserving we call these aggressive abstractions -- and which can therefore be analyzed using the proposed approach. We then introduce and develop two forms of aggressive abstraction: 1.) finite state abstraction, in which dynamical networks with uncountable state spaces are modeled using finite state systems, and 2.) onedimensional abstraction, whereby high dimensional network dynamics are captured in a meaningful way using a single scalar variable. In each case, the property preserving nature of the abstraction process is rigorously established and efficient algorithms are presented for computing the abstraction. The considerable potential of the proposed approach to complex networks analysis is illustrated through case studies involving vulnerability analysis of technological networks and predictive analysis for social processes.

The authors conducted a study to assess the reporting quality of randomized controlled trial (RCT) abstracts published in leading general dental journals, investigate any improvement after the release of the Consolidated Standards of Reporting Trials (CONSORT) for Abstracts guidelines, and identify factors associated with better reporting quality. The authors searched PubMed for RCTs published in 10 leading general dental journals during the periods from 2005 to 2007 (pre-CONSORT period) and 2010 to 2012 (post-CONSORT period). The authors evaluated and scored the reporting quality of included abstracts by using the original 16-item CONSORT for Abstracts checklist. The authors used risk ratios and the t test to compare the adequate reporting rate of each item and the overall quality in the 2 periods. The authors used univariate and multivariate regressions to identify predictors of better reporting quality. The authors included and evaluated 276 RCT abstracts. Investigators reported significantly more checklist items during the post-CONSORT period (mean [standard deviation {SD}], 4.53 [1.69]) than during the pre-CONSORT period (mean [SD], 3.87 [1.10]; mean difference, -0.66 [95% confidence interval, -0.99 to -0.33]; P 80%). In contrast, the authors saw sufficient reporting of randomization, recruitment, outcome in the results section, and funding in none of the pre-CONSORT abstracts and less than 2% of the post-CONSORT abstracts. On the basis of the multivariate analysis, a higher impact factor (P general dental journals has improved significantly, but there is still room for improvement. Joint efforts by authors, reviewers, journal editors, and other stakeholders to improve the reporting of dental RCT abstracts are needed. Copyright © 2015 American Dental Association.

It has however limitations for protocols and web services that are based on databases of keys, contracts, or even access rights, where revocation is possible, so...... that the set of true facts does not monotonically grow with the transitions. We extend the scope of these over-approximation methods by defining a new way of abstraction that can handle such databases, and we formally prove that the abstraction is sound.

Legal Ethics, Rules of Conduct and the Moral Compass – Considerations from a Law Student's Perspective

Directory of Open Access Journals (Sweden)

Christoffel Hendrik van Zyl IV

2016-05-01

Full Text Available When young law graduates enter the legal profession they will undoubtedly be exposed to difficult situations that will demand of them to make difficult decisions, often having to balance conflicting systems of belief and ideas on what ethical behaviour entails. Legal ethics training in law faculties the world over often neglects teaching aspects of morality to focus on reviews of rules of professional legal conduct. This article argues that if legal education is to adequately prepare law graduates for legal practice, it must offer more than reviews of these codes of conduct. To properly assist law students in avoiding pitfalls which may lead to disciplinary action, they must be taught to appropriately use their moral compasses. This narrative aims to show that the metaphorical moral compass, with the cardinal virtues as possible main points, may serve as the crucial and underlying guide in the avoidance of the pitfalls which may result in a person being struck from the roll, but more than that, that it may aid in the pursuit of personal dreams or goals. The article contributes to the literature on legal ethics by foregrounding the virtues that pertain to sound conduct in a lawyer, as opposed to the rules and codes, in the hope that this may help legal practitioners to decide on what is right and what is wrong.

Abstracts accepted as an oral presentation or poster from the 2010 COS Annual Meeting were tabulated by type of presentation (oral vs poster), subspecialty, study design, number of authors, and principal investigator's institution. A PubMed search was conducted for each abstract by key word, first author, and last author. The year of publication, journal, and impact factor were recorded for identified publications. Publication rate was calculated by type of presentation, subspecialty, study design, number of authors, and institution. A total of 175 abstracts were presented at the 2010 COS Annual Meeting. There were 105 oral (60%) and 70 poster (40%) presentations. The overall publication rate was 45.7%; 49.5% for oral presentations and 40.0% for posters. Cornea (57.6%) and public health (54.5%) had the highest publication rates of all subspecialties. Randomized control trials (71.4%) and cohort studies (70.0%) had higher publication rates than other study designs. Overall, 28.8% of abstracts were published in the Canadian Journal of Ophthalmology. The average impact factor of all publications was 2.73. Of abstracts presented at the 2010 COS Annual Meeting, 45.7% were published within 5 years after the conference. This publication rate is within the upper end of previously reported meeting publication rates for medical societies. Copyright © 2017 Canadian Ophthalmological Society. Published by Elsevier Inc.

Kim, Nancy S; Johnson, Samuel G B; Ahn, Woo-Kyoung; Knobe, Joshua

2017-01-01

Human behavior is frequently described both in abstract, general terms and in concrete, specific terms. We asked whether these two ways of framing equivalent behaviors shift the inferences people make about the biological and psychological bases of those behaviors. In five experiments, we manipulated whether behaviors are presented concretely (i.e. with reference to a specific person, instantiated in the particular context of that person's life) or abstractly (i.e. with reference to a category of people or behaviors across generalized contexts). People judged concretely framed behaviors to be less biologically based and, on some dimensions, more psychologically based than the same behaviors framed in the abstract. These findings held true for both mental disorders (Experiments 1 and 2) and everyday behaviors (Experiments 4 and 5), and yielded downstream consequences for the perceived efficacy of disorder treatments (Experiment 3). Implications for science educators, students of science, and members of the lay public are discussed.

ABSTRACT:: Most cardiovascular researchers are familiar with intermediate-conductance KCa3.1 and small-conductance KCa2.3 channels because of their contribution to endothelium-derived hyperpolarization (EDH). However, to immunologists and neuroscientists these channels are primarily known...... for their role in lymphocyte activation and neuronal excitability. KCa3.1 is involved in the proliferation and migration of T cells, B cell, mast cells, macrophages, fibroblasts and dedifferentiated vascular smooth muscle cells and is, therefore, being pursued as a potential target for use in asthma...

Embodied cognition, abstract concepts, and the benefits of new technology for implicit body manipulation

Science.gov (United States)

Dijkstra, Katinka; Eerland, Anita; Zijlmans, Josjan; Post, Lysanne S.

2014-01-01

Current approaches on cognition hold that concrete concepts are grounded in concrete experiences. There is no consensus, however, as to whether this is equally true for abstract concepts. In this review we discuss how the body might be involved in understanding abstract concepts through metaphor activation. Substantial research has been conducted on the activation of common orientational metaphors with bodily manipulations, such as “power is up” and “more is up” representations. We will focus on the political metaphor that has a more complex association between the concept and the concrete domain. However, the outcomes of studies on this political metaphor have not always been consistent, possibly because the experimental manipulation was not implicit enough. The inclusion of new technological devices in this area of research, such as the Wii Balance Board, seems promising in order to assess the groundedness of abstract conceptual spatial metaphors in an implicit manner. This may aid further research to effectively demonstrate the interrelatedness between the body and more abstract representations. PMID:25191282

2011-10-01

Full Text Available Abstract Background Abstractor training is a key element in creating valid and reliable data collection procedures. The choice between in-person vs. remote or simultaneous vs. sequential abstractor training has considerable consequences for time and resource utilization. We conducted a web-based (webinar abstractor training session to standardize training across six individual Cancer Research Network (CRN sites for a study of breast cancer treatment effects in older women (BOWII. The goals of this manuscript are to describe the training session, its participants and participants' evaluation of webinar technology for abstraction training. Findings A webinar was held for all six sites with the primary purpose of simultaneously training staff and ensuring consistent abstraction across sites. The training session involved sequential review of over 600 data elements outlined in the coding manual in conjunction with the display of data entry fields in the study's electronic data collection system. Post-training evaluation was conducted via Survey Monkey©. Inter-rater reliability measures for abstractors within each site were conducted three months after the commencement of data collection. Ten of the 16 people who participated in the training completed the online survey. Almost all (90% of the 10 trainees had previous medical record abstraction experience and nearly two-thirds reported over 10 years of experience. Half of the respondents had previously participated in a webinar, among which three had participated in a webinar for training purposes. All rated the knowledge and information delivered through the webinar as useful and reported it adequately prepared them for data collection. Moreover, all participants would recommend this platform for multi-site abstraction training. Consistent with participant-reported training effectiveness, results of data collection inter-rater agreement within sites ranged from 89 to 98%, with a weighted average of

Exploring Prospective Teachers’ Reflections in the Context of Conducting Clinical Interviews

Full Text Available This study investigated prospective mathematics teachers’ reflections on the experience of designing and conducting one-to-one clinical interviews with middle school students in the context of an elective course on use of video in teacher learning. Prospective teachers were asked to write about weaknesses and strengths in student understanding as well as their own performance as an interviewer in terms of asking questions and responding to student thinking in their reflections on conducting clinical interviews. Furthermore, prospective teachers were also asked to reflect on what they would do differently in order to conduct better clinical interviews. Nature of prospective teachers’ reflections were analyzed by using existing frameworks (through constructs of reflection-on-action and reflection-for-action and by using thematic analysis. Results of data analyses revealed that prospective teachers had more difficulties in providing meaningful reflection-for-action which was related to alternative decisions and planning for future similar interviews. Thematic analysis results revealed prospective teachers’ learning were grouped under three categories: conducting clinical interviews as part of being a teacher, complexity of conducting clinical interviews, and personal theories about middle school students. There are implications for both teacher learning and research.

Conceptualizing ¬the Abstractions of Earthquakes Through an Instructional Sequence Using SeisMac and the Rapid Earthquake Viewer

Taber, J.; Hubenthal, M.; Wysession, M.

2007-12-01

Newsworthy earthquakes provide an engaging hook for students in Earth science classes, particularly when discussing their effects on people and the landscape. However, engaging students in an analysis of earthquakes that extends beyond death and damage, is frequently hampered by the abstraction of recorded ground motion data in the form of raw seismograms and the inability of most students to personally relate to ground accelerations. To overcome these challenges, an educational sequence has been developed using two software tools: SeisMac by Daniel Griscom, and the Rapid Earthquake Viewer (REV) developed by the University of South Carolina in collaboration with IRIS and DLESE. This sequence presents a unique opportunity for Earth Science teachers to "create" foundational experiences for students as they construction a framework of understanding of abstract concepts. The first activity is designed to introduce the concept of a three-component seismogram and to directly address the very abstract nature of seismograms through a kinesthetic experience. Students first learn to take the pulse of their classroom through a guided exploration of SeisMac, which displays the output of the laptop's built-in Sudden Motion Sensor (a 3-component accelerometer). This exploration allows students to view a 3-component seismogram as they move or tap the laptop and encourages them to propose and carry out experiments to explain the meaning of the 3-component seismogram. Once completed students are then asked to apply this new knowledge to a real 3-component seismogram printed from REV. Next the activity guides students through the process of identifying P and S waves and using SeisMac to connect the physical motion of the laptop to the "wiggles" they see on the SeisMac display and then comparing those to the "wiggles" they see on their seismogram. At this point students are more fully prepared to engage in an S-P location exercise such as those included in many state standards

Investigating how students communicate tree-thinking

Science.gov (United States)

Boyce, Carrie Jo

Learning is often an active endeavor that requires students work at building conceptual understandings of complex topics. Personal experiences, ideas, and communication all play large roles in developing knowledge of and understanding complex topics. Sometimes these experiences can promote formation of scientifically inaccurate or incomplete ideas. Representations are tools used to help individuals understand complex topics. In biology, one way that educators help people understand evolutionary histories of organisms is by using representations called phylogenetic trees. In order to understand phylogenetics trees, individuals need to understand the conventions associated with phylogenies. My dissertation, supported by the Tree-Thinking Representational Competence and Word Association frameworks, is a mixed-methods study investigating the changes in students' tree-reading, representational competence and mental association of phylogenetic terminology after participation in varied instruction. Participants included 128 introductory biology majors from a mid-sized southern research university. Participants were enrolled in either Introductory Biology I, where they were not taught phylogenetics, or Introductory Biology II, where they were explicitly taught phylogenetics. I collected data using a pre- and post-assessment consisting of a word association task and tree-thinking diagnostic (n=128). Additionally, I recruited a subset of students from both courses (n=37) to complete a computer simulation designed to teach students about phylogenetic trees. I then conducted semi-structured interviews consisting of a word association exercise with card sort task, a retrospective pre-assessment discussion, a post-assessment discussion, and interview questions. I found that students who received explicit lecture instruction had a significantly higher increase in scores on a tree-thinking diagnostic than students who did not receive lecture instruction. Students who received both

Hydrogen abstraction reactions by amide electron adducts

Sevilla, M.D.; Sevilla, C.L.; Swarts, S.

1982-01-01

Electron reactions with a number of peptide model compounds (amides and N-acetylamino acids) in aqueous glasses at low temperature have been investigated using ESR spectroscopy. The radicals produced by electron attachment to amides, RC(OD)NDR', are found to act as hydrogen abstracting agents. For example, the propionamide electron adduct is found to abstract from its parent propionamide. Electron adducts of other amides investigated show similar behavior except for acetamide electron adduct which does not abstract from its parent compound, but does abstract from other amides. The tendency toward abstraction for amide electron adducts are compared to electron adducts of several carboxylic acids, ketones, aldehydes and esters. The comparison suggests the hydrogen abstraction tendency of the various deuterated electron adducts (DEAs) to be in the following order: aldehyde DEA > acid DEA = approximately ester DEA > ketone DEA > amide DEA. In basic glasses the hydrogen abstraction ability of the amide electron adducts is maintained until the concentration of base is increased sufficiently to convert the DEA to its anionic form, RC(O - )ND 2 . In this form the hydrogen abstracting ability of the radical is greatly diminished. Similar results were found for the ester and carboxylic acid DEA's tested. (author)

Minimalism in architecture: Abstract conceptualization of architecture

Directory of Open Access Journals (Sweden)

Vasilski Dragana

2015-01-01

Full Text Available Minimalism in architecture contains the idea of the minimum as a leading creative tend to be considered and interpreted in working through phenomena of empathy and abstraction. In the Western culture, the root of this idea is found in empathy of Wilhelm Worringer and abstraction of Kasimir Malevich. In his dissertation, 'Abstraction and Empathy' Worringer presented his thesis on the psychology of style through which he explained the two opposing basic forms: abstraction and empathy. His conclusion on empathy as a psychological basis of observation expression is significant due to the verbal congruence with contemporary minimalist expression. His intuition was enhenced furthermore by figure of Malevich. Abstraction, as an expression of inner unfettered inspiration, has played a crucial role in the development of modern art and architecture of the twentieth century. Abstraction, which is one of the basic methods of learning in psychology (separating relevant from irrelevant features, Carl Jung is used to discover ideas. Minimalism in architecture emphasizes the level of abstraction to which the individual functions are reduced. Different types of abstraction are present: in the form as well as function of the basic elements: walls and windows. The case study is an example of Sou Fujimoto who is unequivocal in its commitment to the autonomy of abstract conceptualization of architecture.

Berta Schnettler

Full Text Available Abstract: The aim of this study was to categorize university students based on their association between food neophobia and levels of subjective well-being, in general and in the food domain, and their perception of their family's eating habits. A survey was conducted among 372 university students from southern Chile. The questionnaire included the Food Neophobia Scale (FNS, Satisfaction with Life Scale (SWLS, Satisfaction with Food-related Life (SWFL, Health-related Quality of Life Index (HRQOL-4, and Family Eating Habits Questionnaire (FEHQ. Three student types were distinguished by cluster analysis: Group 1 (26.9% had the highest scores on the FNS, SWLS and SWFL. Group 2 (40.8% had a high score on the FNS but the lowest scores on the SWLS and SWFL. Group 3 (32.3% had the lowest FNS score and high scores on the SWLS and SWFL. Group 2 stood out in having a low score on the FEHQ's component for cohesiveness of family eating. These results suggest that both neophobic and non-neophobic students have positive levels of satisfaction with life and food-related life, and that satisfaction among neophobic students is related to family eating patterns, especially cohesiveness in family eating.

The Complexity of Abstract Machines

Directory of Open Access Journals (Sweden)

Beniamino Accattoli

2017-01-01

Full Text Available The lambda-calculus is a peculiar computational model whose definition does not come with a notion of machine. Unsurprisingly, implementations of the lambda-calculus have been studied for decades. Abstract machines are implementations schema for fixed evaluation strategies that are a compromise between theory and practice: they are concrete enough to provide a notion of machine and abstract enough to avoid the many intricacies of actual implementations. There is an extensive literature about abstract machines for the lambda-calculus, and yet—quite mysteriously—the efficiency of these machines with respect to the strategy that they implement has almost never been studied. This paper provides an unusual introduction to abstract machines, based on the complexity of their overhead with respect to the length of the implemented strategies. It is conceived to be a tutorial, focusing on the case study of implementing the weak head (call-by-name strategy, and yet it is an original re-elaboration of known results. Moreover, some of the observation contained here never appeared in print before.

Abstraction of man-made shapes

KAUST Repository

Mehra, Ravish; Zhou, Qingnan; Long, Jeremy; Sheffer, Alla; Gooch, Amy Ashurst; Mitra, Niloy J.

2009-01-01

Man-made objects are ubiquitous in the real world and in virtual environments. While such objects can be very detailed, capturing every small feature, they are often identified and characterized by a small set of defining curves. Compact, abstracted shape descriptions based on such curves are often visually more appealing than the original models, which can appear to be visually cluttered. We introduce a novel algorithm for abstracting three-dimensional geometric models using characteristic curves or contours as building blocks for the abstraction. Our method robustly handles models with poor connectivity, including the extreme cases of polygon soups, common in models of man-made objects taken from online repositories. In our algorithm, we use a two-step procedure that first approximates the input model using a manifold, closed envelope surface and then extracts from it a hierarchical abstraction curve network along with suitable normal information. The constructed curve networks form a compact, yet powerful, representation for the input shapes, retaining their key shape characteristics while discarding minor details and irregularities. © 2009 ACM.

This study aims to determine the difficulties of algebraic thinking ability of students in one of secondary school on quadrilateral subject and to describe Math-Talk Learning Community as the alternative way that can be done to overcome the difficulties of the students’ algebraic thinking ability. Research conducted by using quantitative approach with descriptive method. The population in this research was all students of that school and twenty three students as the sample that was chosen by purposive sampling technique. Data of algebraic thinking were collected through essay test. The results showed the percentage of achievement of students’ algebraic thinking’s indicators on three aspects: a) algebra as generalized arithmetic with the indicators (conceptually based computational strategies and estimation); b) algebra as the language of mathematics (meaning of variables, variable expressions and meaning of solution); c) algebra as a tool for functions and mathematical modelling (representing mathematical ideas using equations, tables, or words and generalizing patterns and rules in real-world contexts) is still low. It is predicted that because the secondary school students was not familiar with the abstract problem and they are still at a semi-concrete stage where the stage of cognitive development is between concrete and abstract. Based on the percentage achievement of each indicators, it can be concluded that the level of achievement of student’s mathematical communication using conventional learning is still low, so students’ algebraic thinking ability need to be improved.

Evaluating Data Abstraction Assistant, a novel software application for data abstraction during systematic reviews: protocol for a randomized controlled trial

Full Text Available Abstract Background Data abstraction, a critical systematic review step, is time-consuming and prone to errors. Current standards for approaches to data abstraction rest on a weak evidence base. We developed the Data Abstraction Assistant (DAA, a novel software application designed to facilitate the abstraction process by allowing users to (1 view study article PDFs juxtaposed to electronic data abstraction forms linked to a data abstraction system, (2 highlight (or “pin” the location of the text in the PDF, and (3 copy relevant text from the PDF into the form. We describe the design of a randomized controlled trial (RCT that compares the relative effectiveness of (A DAA-facilitated single abstraction plus verification by a second person, (B traditional (non-DAA-facilitated single abstraction plus verification by a second person, and (C traditional independent dual abstraction plus adjudication to ascertain the accuracy and efficiency of abstraction. Methods This is an online, randomized, three-arm, crossover trial. We will enroll 24 pairs of abstractors (i.e., sample size is 48 participants, each pair comprising one less and one more experienced abstractor. Pairs will be randomized to abstract data from six articles, two under each of the three approaches. Abstractors will complete pre-tested data abstraction forms using the Systematic Review Data Repository (SRDR, an online data abstraction system. The primary outcomes are (1 proportion of data items abstracted that constitute an error (compared with an answer key and (2 total time taken to complete abstraction (by two abstractors in the pair, including verification and/or adjudication. Discussion The DAA trial uses a practical design to test a novel software application as a tool to help improve the accuracy and efficiency of the data abstraction process during systematic reviews. Findings from the DAA trial will provide much-needed evidence to strengthen current recommendations for data

Thermal conductivity analysis and applications of nanocellulose materials

2017-01-01

Abstract In this review, we summarize the recent progress in thermal conductivity analysis of nanocellulose materials called cellulose nanopapers, and compare them with polymeric materials, including neat polymers, composites, and traditional paper. It is important to individually measure the in-plane and through-plane heat-conducting properties of two-dimensional planar materials, so steady-state and non-equilibrium methods, in particular the laser spot periodic heating radiation thermometry method, are reviewed. The structural dependency of cellulose nanopaper on thermal conduction is described in terms of the crystallite size effect, fibre orientation, and interfacial thermal resistance between fibres and small pores. The novel applications of cellulose as thermally conductive transparent materials and thermal-guiding materials are also discussed. PMID:29152020

Abstract Spatial Reasoning as an Autistic Strength

Stevenson, Jennifer L.; Gernsbacher, Morton Ann

2013-01-01

Autistic individuals typically excel on spatial tests that measure abstract reasoning, such as the Block Design subtest on intelligence test batteries and the Raven’s Progressive Matrices nonverbal test of intelligence. Such well-replicated findings suggest that abstract spatial processing is a relative and perhaps absolute strength of autistic individuals. However, previous studies have not systematically varied reasoning level – concrete vs. abstract – and test domain – spatial vs. numerical vs. verbal, which the current study did. Autistic participants (N = 72) and non-autistic participants (N = 72) completed a battery of 12 tests that varied by reasoning level (concrete vs. abstract) and domain (spatial vs. numerical vs. verbal). Autistic participants outperformed non-autistic participants on abstract spatial tests. Non-autistic participants did not outperform autistic participants on any of the three domains (spatial, numerical, and verbal) or at either of the two reasoning levels (concrete and abstract), suggesting similarity in abilities between autistic and non-autistic individuals, with abstract spatial reasoning as an autistic strength.

Engaging students in astronomy and spectroscopy through Project SPECTRA!

Computer simulations for minds-on learning with "Project Spectra!" How do we gain information about the Sun? How do we know Mars has CO2 or that Enceladus has H2O geysers? How do we use light in astronomy? These concepts are something students and educators struggle with because they are abstract. Using simulations and computer interactives (games) where students experience and manipulate the information makes concepts accessible. Visualizing lessons with multi-media solidifies understanding and retention of knowledge and is completely unlike its paper-and-pencil counterpart. Visualizations also enable teachers to forgo purchasing expensive laboratory equipment. "Project Spectra!" is a science and engineering program that uses computer-based Flash interactives to expose students to astronomical spectroscopy and actual data in a way that is not possible with traditional in-class activities. To engage students in "Project Spectra!", students are given a mission, which connects them with the research at hand. Missions range from exploring remote planetary atmospheres and surfaces, experimenting with the Sun using different filters, or analyzing the soil of a remote planet. Additionally, students have an opportunity to learn about NASA missions, view movies, and see images connected with their mission, which is something that is not practical to do during a typical paper-and-pencil activity. Since students can choose what to watch and explore, the interactives accommodate a broad range of learning styles. Students can go back and forth through the interactives if they've missed a concept or wish to view something again. In the end, students are asked critical thinking questions and conduct web-based research. These interactives complement in-class Project SPECTRA! activities exploring applications of the electromagnetic spectrum.

Full Text Available Abstract Background Burnout syndrome (BS is a set of psychological symptoms resulting from the interaction between chronic occupational stress and individual factors. These symptoms include emotional exhaustion, depersonalization and decreased professional satisfaction. BS is manifested in a variety of professions and is prevalent in contexts in which health professionals are required to interact directly with the public. Objective To determine the prevalence of BS among medical students at a university in Ceará State, Brazil. Methods Of the 517 students enrolled in their first to eighth semester in 2013, 376 (72.7% were contacted. A socio-economic evaluation questionnaire and the Maslach Burnout Inventory – Human Services Survey (MBI-HSS were administered. Statistical analysis was conducted using SPSS 20.0. Two groups – burnout/risk and non-burnout – were compared using the chi-square and likelihood ratio tests with a significance level of 5%. Variables with p < 0.20 were included in a multivariate analysis logistical regression model. Results Burnout was detected in 14.9% of the students, and 57.7% showed a risk of developing the syndrome. Logistic regressions showed an association between burnout and “have failed examinations” and “have considered abandoning the course”, p = 0.047 and p < 0.0001, respectively. Discussion Psychopedagogy should be implemented to address the high prevalence of burnout in medical students.

Full Text Available The practice of teaching, in actuality, shows the necessity of teachers and students coming together to form a behavior that is different from the traditional model of teaching. The unity formed from various types of knowledge and the relation between theory and practice show themselves to be fundamental. Starting in 2002, and in search of this unity, a project that hoped to unify the disciplines taught in the second semester of the course in Administration was implemented. During the semester, a single work sought to relate the theories studied with the reality of an organization. Each professor evaluated the works from the point of view of his discipline, as well as the presentation, in general, of the group. It can be affirmed that seeking to bring together various types of knowledge necessarily passes to a rethinking of the postures of teachers and students.

2004-10-01

Full Text Available The paper examines the abstract genre from the perspectives of English for Specific Purposes (ESP practitioners and information professionals. It aims to determine specific interdisciplinary interests in the abstract, and to explore areas of collaboration in terms of research and pedagogical practices. A focus group (FG comprising information professionals from the Division of Information Studies, Nanyang Technological University, Singapore, convened for a discussion on the subject of abstracts and abstracting. Two major issues that have significant implications for ESP practices emerged during the discussion. While differences in terms of approach to and objectives of the abstract genre are apparent between information professionals and language professionals, the demands for specific cognitive processes involved in abstracting proved to be similar. This area of similarity provides grounds for awareness raising and collaboration between the two disciplines. While ESP practitioners need to consider adding the dimension of information science to the rhetorical and linguistic scaffolding that they have been providing to novice-writers, information professionals can contribute useful insights about the qualities of abstracts that have the greatest impact in meeting the end-users' needs in information search.

Full Text Available Abstract A cross-sectional population-based study using questionnaire and anthropometric data was conducted on 968 university students of São Luís, Brazil, from which 590 showed up for blood collection. In the statistical analysis the Student t-test, Mann-Whitney and chi-square tests were used. The prevalence of metabolic syndrome by the Joint Interim Statement (JIS criteria was 20.5%, almost three times more prevalent in men (32.2% than in women (13.5% (P < 0.001. The prevalence of insulin resistance was 7.3% and the prevalence of low HDL-cholesterol was high (61.2%, both with no statistically significant differences by sex. Men showed a higher percentage of smoking, overweight, high blood pressure, high blood glucose and increased fasting hypertriglyceridemia. Women were more sedentary. University students of private institutions had higher prevalences of sedentary lifestyle, obesity, abdominal obesity, elevated triglycerides and metabolic syndrome than students from public institutions. High prevalences of metabolic syndrome, insulin resistance and other cardiovascular risk factors were found in this young population. This suggests that the burden of these diseases in the future will be increased.

Abstracting audit data for lightweight intrusion detection

KAUST Repository

Wang, Wei

2010-01-01

High speed of processing massive audit data is crucial for an anomaly Intrusion Detection System (IDS) to achieve real-time performance during the detection. Abstracting audit data is a potential solution to improve the efficiency of data processing. In this work, we propose two strategies of data abstraction in order to build a lightweight detection model. The first strategy is exemplar extraction and the second is attribute abstraction. Two clustering algorithms, Affinity Propagation (AP) as well as traditional k-means, are employed to extract the exemplars, and Principal Component Analysis (PCA) is employed to abstract important attributes (a.k.a. features) from the audit data. Real HTTP traffic data collected in our institute as well as KDD 1999 data are used to validate the two strategies of data abstraction. The extensive test results show that the process of exemplar extraction significantly improves the detection efficiency and has a better detection performance than PCA in data abstraction. © 2010 Springer-Verlag.

Full Text Available Abstract Background Ego defense mechanisms (or factors, defined by Freud as unconscious resources used by the ego to reduce conflict between the id and superego, are a reflection of how an individual deals with conflict and stress. This study assesses the prevalence of various ego defense mechanisms employed by medical students of Karachi, which is a group with higher stress levels than the general population. Methods A questionnaire based cross-sectional study was conducted on 682 students from five major medical colleges of Karachi over 4 weeks in November 2006. Ego defense mechanisms were assessed using the Defense Style Questionnaire (DSQ-40 individually and as grouped under Mature, Immature, and Neurotic factors. Results Lower mean scores of Immature defense mechanisms (4.78 were identified than those for Neurotic (5.62 and Mature (5.60 mechanisms among medical students of Karachi. Immature mechanisms were more commonly employed by males whereas females employed more Neurotic mechanisms than males. Neurotic and Immature defenses were significantly more prevalent in first and second year students. Mature mechanisms were significantly higher in students enrolled in Government colleges than Private institutions (p Conclusions Immature defense mechanisms were less commonly employed than Neurotic and Mature mechanisms among medical students of Karachi. The greater employment of Neurotic defenses may reflect greater stress levels than the general population. Employment of these mechanisms was associated with female gender, enrollment in a private medical college, and students enrolled in the first 2 years of medical school.

Abstracts presented at medical conferences or scientific meetings should ideally be published as full-text articles in peer-reviewed journals after initial presentation and feedback regardless of the findings. The aim of this survey was to determine the publication rate of papers presented at the Danish Emergency Medicine Conferences in 2009, 2010 and 2011. Abstracts presented at the conferences were identified and authors contacted to obtain publication information. A further search was conducted using relevant databases. Publication rates for the 2009 and 2010 were approximately 30% (25-31.6%). The publication rate for the 2011 conference was 14.5% within 18 months with an additional 9% under review prior to publication. When comparing full-text publication rates from DEMC to previous international studies in EM Danish EM research community has similar publication rates. However, other more established specialties have higher publication levels. Knowledge of reasons for non-publication could lead to efforts to promote publication like funding; the possibility of discussion between authors and editors at conferences; "publication mentors"; and/or research courses provided by the Danish Society of Emergency Medicine.

2012-04-01

Full Text Available Abstract Background Migration and ethical recruitment of health care workers is receiving increased attention worldwide. Europe’s aging population is creating new opportunities for medical doctors for finding employment in other countries, particularly those of a better standard of living. Methods We conducted a survey among 1214 medical students in five out of eleven universities in Poland with medical schools in October 2008. A series of statistical tests was applied to analyse the characteristics of potential migrants. Projections were obtained using statistical analyses: descriptive, multifactorial logistic regression and other statistical methods . Results We can forecast that 26–36% of Polish medical students will emigrate over the next few years; 62% of respondents estimated the likelihood of emigration at 50%. Students in their penultimate year of study declared a stronger desire to migrate than those in the final year. At the same time, many students were optimistic about career opportunities in Poland. Also noted among students were: the decline in interest in leaving among final year students, their moderate elaboration of departure plans, and their generally optimistic views about the opportunities for professional development in Poland. Conclusions The majority of Polish students see the emigration as a serious alternative to the continuation of their professional training. This trend can pose a serious threat to the Polish health care system, however the observed decline of the interest in leaving among final year students, the moderate involvement in concrete departure plans and the optimistic views about the opportunities for professional development in Poland suggest that the actual scale of brain drain of young Polish doctors due to emigration will be more limited than previously feared.

2015-12-01

Student to Scientist (S2S), provides pathways for observational and research tools for K-12 and undergraduate students to improve science proficiency through conducting real scientific observations. Our approach lies in the integration of professional and amateur astronomers, educators, students, and communicators to identify multiple paths for the student to become a scientist. I report on the ensuing project, also known as the PACA Project, which is an ecosystem of various activities that take advantage of the social media and immediate connectivity amongst amateur astronomers worldwide and that can be galvanized to participate in a given observing campaign. The PACA Project has participated in organized campaigns such as NASA Comet ISON Observing Campaign in 2013; NASA Comet Integrated Observations Campaign to observe Comet Siding Spring as it flew by very close to Mars on 19 October 2014. Currently the PACA Project is involved in the Ground-based Amateur campaign to observer ESA/Rosetta mission's target, 67P/Churyumov-Gerasimenko (CG) that is en route to its perihelion on 13 August 2015 (at the time of abstract submission). The PACA Project provides access to the professional community and the student/educator and informal/public communities via various social media like Facebook, Twitter, Flickr, Pinterest, Vimeo, Google+. With the popularity of mobile platforms and instant connections with other peers globally, the multi-faceted social universe has become a vital part of engagement of multiple communities. The PACA project currently has initiated a Comet Tails and Disconnection Events campaign to relate to the changing solar wind conditions. Other PACA projects include Saturn Solstice 2017 and outreach projects with Astroproject (India). These and other citizen-science enabled activities and their integration with S2S project will be discussed.

Full Text Available Abstract Background Evaluation is an integral part of medical education. Despite a wide use of various evaluation tools, little is known about student perceptions regarding the purpose and desired consequences of evaluation. Such knowledge is important to facilitate interpretation of evaluation results. The aims of this study were to elicit student views on the purpose of evaluation, indicators of teaching quality, evaluation tools and possible consequences drawn from evaluation data. Methods This qualitative study involved 17 undergraduate medical students in Years 3 and 4 participating in 3 focus group interviews. Content analysis was conducted by two different researchers. Results Evaluation was viewed as a means to facilitate improvements within medical education. Teaching quality was believed to be dependent on content, process, teacher and student characteristics as well as learning outcome, with an emphasis on the latter. Students preferred online evaluations over paper-and-pencil forms and suggested circulating results among all faculty and students. Students strongly favoured the allocation of rewards and incentives for good teaching to individual teachers. Conclusions In addition to assessing structural aspects of teaching, evaluation tools need to adequately address learning outcome. The use of reliable and valid evaluation methods is a prerequisite for resource allocation to individual teachers based on evaluation results.

Feller, Tara T; Doucette, William R; Witry, Matthew J

2016-06-25

Objective. To summarize student pharmacist leadership development opportunities delivered by pharmacy programs, to describe selected opportunities, and to assess how these opportunities meet leadership development competencies. Methods. A multi-method study was conducted that comprised a systematic content analysis of pharmacy education journals, pharmacy program websites, and telephone interviews with key informants, which included open-ended questions and scaled responses. Results. Review of six articles, 37 American Association of Colleges of Pharmacy (AACP) Annual Meeting abstracts, and 138 websites resulted in the identification of 191 leadership development opportunities. These consisted of courses, projects/programs, and events/speaker series. Interviews with 12 key informants detailed unique events that developed leadership competencies. Formal assessments of student leadership development were limited and primarily focused on informal feedback and course evaluations. Conclusion. Most US pharmacy programs offer their students an array of opportunities to develop leadership abilities. Pharmacy programs should consider expanding opportunities beyond elective courses, learn from the successes of others to implement new leadership development opportunities, and bolster the assessment of student leadership competencies and outcomes.

Transfer value of learning music on cognitive development of elementary school and high school students

Directory of Open Access Journals (Sweden)

Vujošević Nevena J.

2016-01-01

Full Text Available Examining positive effects of music on cognitive development is often part of empirical researches within cognitive and general psychology of music. Starting from the studies conducted by the most modern technologies and methods of studying interconnectedness of mental processes and individual musical development, the conclusion is that active musical participation influences a large specter of enhancing the student's abilities even within other cognitive areas of his actions. Positive effects of music influence directly the development of student's verbal and visual-spatial abilities, abstract thinking, movement coordination, concentration and memory capacity, creativity in thinking and task solving, as well as the development of emotional, aesthetic and social intelligence of the individual. Some of them will be especially stressed in the paper. The paper informs about newer results of examining positive effects of music on non-musical cognitive abilities of students and indicates to positive implications that music and musical education can enhance overall cognitive development of personality.

Walby, A; Kelly, A M; Georgakas, C

2001-12-01

The aims of the present study were to determine the publication rate of abstracts presented by Australasian emergency physicians at major emergency medicine meetings and to identify the site of publication of papers. All free paper abstracts presented (oral and poster) by Australasian emergency physicians and trainees at five Australasian College for Emergency Medicine/Australasian Society for Emergency Medicine and International Conference on Emergency Medicine meetings between 1995 and 1998 were identified retrospectively from conference programmes. In order to determine whether or not the abstract had been published, the PubMed database (http://www4.ncbi.nlm.nih.gov/PubMed/) was searched using the presenter's name and key words from the abstract. In addition, a hand search of the non-abstracted journal Emergency Medicine was conducted. Of the 207 free paper abstracts identified, 73 (35%) had been published as full articles. Papers were published in a variety of journals; however, Emergency Medicine accounted for almost half the published papers. The mean time between presentation and publication was 12.6 months (median 11 months). The abstract to publication rate for papers presented by Australasian emergency physicians and trainees at Australasian College for Emergency Medicine/Australasian Society for Emergency Medicine and International Conference on Emergency Medicine meetings is 35%, which is lower than that reported by some other established specialities, but comparable to rates reported for US-based national and international emergency medicine meetings. Future research should look at barriers to the publication of findings and ways to assist the publication process.

2007-09-15

The thermal conductivity of electron-beam physical vapor deposited (EB-PVD) thermal barrier coatings (TBCs) was investigated by the Laser Flash technique. Sample type and methodology of data analyses as well as atmosphere during the measurement have some influence on the data. A large variation of the thermal conductivity was found by changes in TBC microstructure. Exposure at high temperature caused sintering of the porous microstructure that finally increased thermal conductivity up to 30 %. EB-PVD TBCs show a distinct thickness dependence of the thermal conductivity due to the anisotropic microstructure in thickness direction. Thin TBCs had a 20 % lower thermal conductivity than thick coatings. New compositions of the ceramic top layer offer the largest potential to lower thermal conductivity. Values down to 0.8W/(mK) have been already demonstrated with virgin coatings of pyrochlore compositions. (Abstract Copyright [2007], Wiley Periodicals, Inc.)

Duenne TBCs haben eine um 20 % geringere Waermeleitfaehigkeit als dicke Schichten. Neue Zusammensetzungen der keramischen Deckschicht bieten die groessten Moeglichkeiten fuer eine Reduktion der Waermeleitfaehigkeit. Werte bis zu 0,8 W/(mK) wurden damit bereits erreicht.

Graphical abstract: Temperature dependence of conductivity, the number of density and proton mobility in chitosan-acetate film. - Highlights: • DD, conductivity, Vogel temperature dependent on the concentration of acetic acid. • Proton conductivity of CS-acetate films interpreted using two Grotthuss mechanisms. • Transformation between two mechanisms observed at the glass transition temperature. - Abstract: The effect of aqueous acetic acid solution concentration during the preparation of chitosan-acetate (CS-acetate) films on the conductivity and relaxation properties were studied by dielectric and FTIR spectroscopies, TGA measurements and X-Ray diffraction. Analyses of the experimental results on the degree of deacetylation, water absorption, conductivity, Vogel temperature and activation energy demonstrate a strong dependence of these parameters on the concentration of the acid acetic solutions from which the films have been obtained. The proton conductivity and relaxation properties of CS-acetate films have been interpreted using two Grotthuss “structural diffusion” and “pack-acid” mechanisms. The transformation between these two mechanisms observed at temperature higher than CS-acetate glass transition temperature is due to an increase in the thermal motion of CS chains, water evaporation, hydrogen bond between water molecules and side groups of CS breaking and formation of new bonds between NH 3 + and acetate ions. Additionally, application of the Rice and Roth model allowed estimating the temperature dependence of proton number and their mobility in CS-acetate films. A systematic interpretation on the appropriate conductivity mechanism will help trigger the design of smart materials used in flexible electronic, solid polymer electrolytes for fuel cells and solid polymer batteries based on CS-acetate films.

Self-regulated learning in higher education: strategies adopted by computer programming students when supported by the SimProgramming approach

Directory of Open Access Journals (Sweden)

Daniela Pedrosa

Full Text Available Abstract The goal of the SimProgramming approach is to help students overcome their learning difficulties in the transition from entry-level to advanced computer programming, developing an appropriate set of learning strategies. We implemented it at the University of Trás-os-Montes e Alto Douro (Portugal, in two courses (PM3 and PM4 of the bachelor programmes in Informatics Engineering and ICT. We conducted semi-structured interviews with students (n=38 at the end of the courses, to identify the students’ strategies for self-regulation of learning in the assignment. We found that students changed some of their strategies from one course edition to the following one and that changes are related to the SimProgramming approach. We believe that changes to the educational approach were appropriate to support the assignment goals. We recommend applying the SimProgramming approach in other educational contexts, to improve educational practices by including techniques to help students in their learning.

Full Text Available Abstract Background Depression is an important global public health problem. Given the scarcity of studies involving African youths, this study was conducted to evaluate the associations of anger expression and violent behavior with symptoms of depression among male college students. Methods A self-administered questionnaire was used to collect information on socio-demographic and lifestyle characteristics and violent behavior among 1,176 college students in Awassa, Ethiopia in June, 2006. The questionnaire incorporated the Spielberger Anger-Out Expression (SAOE scale and symptoms of depression were evaluated using the Patient Health Questionnaire (PHQ-9. Multivariable logistic regression procedures were used to calculate adjusted odds ratios (OR and 95% confidence intervals (95%CI. Results Symptoms of depression were evident in 23.6% of participants. Some 54.3% of students reported committing at least one act of violence in the current academic year; and 29.3% of students reported high (SAOE score ≥ 15 levels of anger-expression. In multivariate analysis, moderate (OR = 1.97; 95%CI 1.33–2.93 and high (OR = 3.23; 95%CI 2.14–4.88 outward anger were statistically significantly associated with increased risks of depressive symptoms. Violent behavior was noted to be associated with depressive symptoms (OR = 1.82; 95%CI 1.37–2.40. Conclusion Further research should be conducted to better characterize community and individual level determinants of anger-expression, violent behavior and depression among youths.

2010-04-01

Research conducted in the past ten years in the area of stress and coping among Arab medical students has identified some important issues, but other significant aspects have not yet been explored. To provide a systematic review of studies reporting on stress, anxiety and coping among Arab medical students and to identify implications for future research. PubMed was searched to identify peer-reviewed English-language studies published between January 1998 and October 2009 reporting on stress and coping among undergraduate Arab medical students. Search strategy used combinations of the terms: Arab medical student, stress, PBL, psychological distress, depression, anxiety and coping strategies. Demographic information on respondents, instruments used, prevalence data and statistically significant associations were abstracted. The search identified 8 articles that met the specified inclusion criteria. Within the limited range of Arab medical students studied, studies suggest these students have a high prevalence of perceived stress, depression and anxiety, with levels of perceived psychological stress as high as those reported in the international literature for medical students of other regions of the world. Limited data were available regarding coping strategies, the impact of stress on academic performance and attrition among Arab students. No data were available regarding the impact of problem-based learning on stress and coping. The existing literature confirms that stress, depression and anxiety are common among Arab medical students, as for students elsewhere. Little is known about the contribution of different curricula approaches to perceived stress and what coping strategies institutions and students apply to help alleviate stress. Large, prospective, multicentre, multi-method studies are needed to identify personal and curricula features that influence stress, depression, anxiety and coping strategies among Arab students.

Conceptual understanding is one of the most important aspects in the study of Physics because of it useful to understand principles behind certain phenomenon which happened. An innovative method was needed to strengthen and enhance student's conceptual understanding, especially regarding the abstract subject such as magnetic field. For this reason, worksheet and exploration sheet based on PDEODE*E (Predict, Discuss, Explain, Observe, Discuss, Explore, and Explain) that uses Gauss Meter application as the smartphone technology has been designed to answer the problem. The magnetic field strength in different mediums is the physics subject which covered in this research. The research was conducted with the aim to know how effective smartphone technology-based PDEODE*E could be implemented as a physics learning strategy. The result of this research shows that students could show improvements in conceptual understanding that shown by the conclusion that was constructed during the learning process. Based on this result, PDEODE*E could become a solution to strengthen students' conceptual understanding regarding physics subject, especially those that requires abstract thinking. This result also has shown that the application ofsmartphone technology could be used to support physics learning processes in the classroom, such as Gauss Meter in this research which used to measure the magnetic field, Light Meter which could be used in the concept of light, and Harmonicity Meter for the context of the sound wave.

Photochemical hydrogen abstractions as radiationless transitions

International Nuclear Information System (INIS)

Burrows, H.D.; Formosinho, S.J.

1977-01-01

The tunnel-effect theory of radiationless transitions is applied to the quenching of the uranyl ion excited state by aliphatic compounds. The most important mechanism kinetically is suggested to involve chemical quenching via hydrogen abstraction, and rates for these reactions are analysed theoretically. Good agreement between theory and experiment is observed for a number of alcohols and ethers, and the reactions are suggested to possess considerable charge-transfer character. With t-butanol it is suggested that abstraction occurs preferentially from the hydroxylic hydrogen. Theoretical analysis of the rates of hydrogen abstraction from carboxylic acids suggests that the reaction geometry in this case may be different from the reaction with alcohols or ethers. The possibility that excited uranyl ion can abstract a hydrogen atom from water is examined, and theoretical evidence is presented to suggest that this is the main route for deactivation of uranyl ion lowest excited state in water at room temperature.

2009-01-01

Abstractions are used in model checking to tackle problems like state space explosion or modeling of IO. The application of these abstractions in real software development processes, however, lacks engineering support. This is one reason why model checking is not widely used in practice yet...... and testing is still state of the art in falsification. We show how user-defined abstractions can be integrated into a Java PathFinder setting with tools like AspectJ or Javassist and discuss implications of remaining weaknesses of these tools. We believe that a principled engineering approach to designing...... and implementing abstractions will improve the applicability of model checking in practice....

Attracting Girls into Physics (abstract)

Gadalla, Afaf

2009-04-01

A recent international study of women in physics showed that enrollment in physics and science is declining for both males and females and that women are severely underrepresented in careers requiring a strong physics background. The gender gap begins early in the pipeline, from the first grade. Girls are treated differently than boys at home and in society in ways that often hinder their chances for success. They have fewer freedoms, are discouraged from accessing resources or being adventurous, have far less exposure to problem solving, and are not encouraged to choose their lives. In order to motivate more girl students to study physics in the Assiut governorate of Egypt, the Assiut Alliance for the Women and Assiut Education District collaborated in renovating the education of physics in middle and secondary school classrooms. A program that helps in increasing the number of girls in science and physics has been designed in which informal groupings are organized at middle and secondary schools to involve girls in the training and experiences needed to attract and encourage girls to learn physics. During implementation of the program at some schools, girls, because they had not been trained in problem-solving as boys, appeared not to be as facile in abstracting the ideas of physics, and that was the primary reason for girls dropping out of science and physics. This could be overcome by holding a topical physics and technology summer school under the supervision of the Assiut Alliance for the Women.

This paper considers the development of a method for abstracting continuous dynamical systems by timed automata. The method is based on partitioning the state space of dynamical systems with invariant sets, which form cells representing locations of the timed automata. To enable verification...... of the dynamical system based on the abstraction, conditions for obtaining sound, complete, and refinable abstractions are set up. It is proposed to partition the state space utilizing sub-level sets of Lyapunov functions, since they are positive invariant sets. The existence of sound abstractions for Morse......-Smale systems and complete and refinable abstractions for linear systems are shown....

Purpose: This study's aim was to characterize the nature of students' research conducted for a Master of Science in Physical Therapy (MScPT) degree programme at a Canadian university and evaluate the lead advisors' perspectives of its impact on their research capacity, education, clinical practice, knowledge translation, and health policy. Methods: We conducted a quantitative, cross-sectional, retrospective review of research reports from 2003 to 2014 to characterize the MScPT students' research and a quantitative, cross-sectional e-survey of lead research advisors to evaluate the impact of this research. Results: Data were abstracted from reports of 201 research projects completed between 2003 and 2014. Projects were conducted primarily in university-affiliated hospitals (41.6%) or the university's physical therapy department (41.1%), and the majority (52.5%) had a clinical focus. Of the 95 lead advisors of 201 projects, 59 advisors (response rate 62.1%) of 119 projects completed the survey questionnaire. The respondents most frequently identified clinical practice (45.1%) and advisors' research capacity (31.4%) as areas positively affected by the students' research. Conclusions: The MScPT students' research projects facilitate the conduct of extensive research internally and across affiliated hospitals. This research appears to advance not only clinical practice but also the ability of lead advisors to undertake research.

2013-01-01

Full Text Available Abstract Background The knowledge of scientific dishonesty is scarce and heterogeneous. Therefore this study investigates the experiences with and the attitudes towards various forms of scientific dishonesty among PhD-students at the medical faculties of all Norwegian universities. Method Anonymous questionnaire distributed to all post graduate students attending introductory PhD-courses at all medical faculties in Norway in 2010/2011. Descriptive statistics. Results 189 of 262 questionnaires were returned (72.1%. 65% of the respondents had not, during the last year, heard or read about researchers who committed scientific dishonesty. One respondent had experienced pressure to fabricate and to falsify data, and one had experienced pressure to plagiarize data. On average 60% of the respondents were uncertain whether their department had a written policy concerning scientific conduct. About 11% of the respondents had experienced unethical pressure concerning the order of authors during the last 12 months. 10% did not find it inappropriate to report experimental data without having conducted the experiment and 38% did not find it inappropriate to try a variety of different methods of analysis to find a statistically significant result. 13% agreed that it is acceptable to selectively omit contradictory results to expedite publication and 10% found it acceptable to falsify or fabricate data to expedite publication, if they were confident of their findings. 79% agreed that they would be willing to report misconduct to a responsible official. Conclusion Although there is less scientific dishonesty reported in Norway than in other countries, dishonesty is not unknown to doctoral students. Some forms of scientific misconduct are considered to be acceptable by a significant minority. There was little awareness of relevant policies for scientific conduct, but a high level of willingness to report misconduct.

In the last years research on the didactics of Psychiatry and opinions of medical students on Psychiatry has gained great interest. The authors think that this research could be useful for the improvement of didactics, for better understanding the meanings of professional choice, the identity of psychiatrist and their relationship with colleagues in other medical field. The goal of this research work was a preliminary survey of Genoese University Medical Student's opinions about psychiatry didactics, and choice of specialization. A questionnaire was submitted to all the students who passed Clinical Psychiatry examination in the period from November 1987 to December 1988. The students were divided in two randomized groups: the first group of students (224) was submitted to the questionnaire immediately after Clinical Psychiatry examination; while to the second group of students (66) the questionnaire was mailed. The aim of the questions was to assess the student's opinions on psychiatry, psychoanalysis, psychotherapy, the career they wanted to take up, and the difficulties of studying psychiatry: 69% of the students of the first group and 42% of the students of the second group answered the questionnaire. Female students answered that they preferred psychiatric specialization more than their male colleagues did, but the difference has no statistical importance. In most cases, the students who answered that they have taken into account psychiatry as a choice of specialisation, are more interested in medical specialties (primary care, etc.) than in surgical specialties. Most of the medical students declare some emotional troubles (anxiety, sleeplessness, problem in social relations).(ABSTRACT TRUNCATED AT 250 WORDS)

In the present study, we examined the nutritional knowledge and food habits of Chinese university students and compared them with those of other Asian populations. Methods A self-reported questionnaire was administered to 540 students, ranging in age from 19-24 years. Medical students from Beijing University (135 men and 150 women in Northern China and Kunming Medical College in southern China (95 men and 160 women participated in this study. The parametric variables were analyzed using the Student's t-test. Chi-square analyses were conducted for non-parametric variables Results Our results showed that 80.5% of students had a normal BMI and 16.6 % of students were underweight with the prevalence of BMI>30 obesity being very low in this study sample. Young Chinese female students had a greater desire to be thinner (62.0% than males (47.4%. Habits involving regular eating patterns and vegetable intake were reported and represent practices that ought to be encouraged. Conclusions The university and college arenas represent the final opportunity for the health and nutritional education of a large number of students from the educator's perspective. Our findings suggest the need for strategies designed to improve competence in the area of nutrition.

Quality improvement (QI) requires measurement, but medical schools rarely provide opportunities for students to measure their patient outcomes. The authors tested the feasibility and perceived impact of a quality metric report card as part of an Education-Centered Medical Home longitudinal curriculum. Student teams were embedded into faculty practices and assigned a panel of patients to follow longitudinally. Students performed retrospective chart reviews and reported deidentified data on 30 nationally endorsed QI metrics for their assigned patients. Scorecards were created for each clinic team. Students completed pre/post surveys on self-perceived QI skills. A total of 405 of their patients' charts were abstracted by 149 students (76% response rate; mean 2.7 charts/student). Median abstraction time was 21.8 (range: 13.1-37.1) minutes. Abstracted data confirmed that the students had successfully recruited a "high-risk" patient panel. Initial performance on abstracted quality measures ranged from 100% adherence on the use of beta-blockers in postmyocardial infarction patients to 24% on documentation of dilated diabetic eye exams. After the chart abstraction assignment, grand rounds, and background readings, student self-assessment of their perceived QI skills significantly increased for all metrics, though it remained low. Creation of an actionable health care quality report card as part of an ambulatory longitudinal experience is feasible, and it improves student perception of QI skills. Future research will aim to use statistical process control methods to track health care quality prospectively as our students use their scorecards to drive clinic-level improvement efforts.

Feminist Physics Education: Deconstructed Physics and Students' Multiple Subjectivities

Science.gov (United States)

Jammula, Diane Crenshaw

Physics is one of the least diverse sciences; in the U.S. in 2010, only 21% of bachelors degrees in physics were awarded to women, 2.5% to African Americans, and 4% to Hispanic Americans (AIP, 2012). Though physics education reform efforts supporting interactive engagement have doubled students' learning gains (Hake, 1998), gender and race gaps persist (Brewe et al., 2010; Kost, Pollock, & Finkelstein, 2009). When students' subjectivities align with presentations of physics, they are more likely to develop positive physics identities (Hughes, 2001). However, both traditional and reformed physics classrooms may present physics singularly as abstract, elite, and rational (Carlone, 2004). Drawing from feminist science, I argue that binaries including abstract / concrete, elite / accessible, and rational / emotional are hierarchal and gendered, raced and classed. The words on the left define conventional physics and are associated with middle class white masculinity, while the words on the right are associated with femininity or other, and are often missing or delegitimized in physics education, as are females and minorities. To conceptualize a feminist physics education, I deconstructed these binaries by including the words on the right as part of doing physics. I do not imply that women and men think differently, but that broadening notions of physics may allow a wider range of students to connect with the discipline. I used this conceptual framework to modify a popular reformed physics curriculum called Modeling Instruction (Hestenes, 1987). I taught this curriculum at an urban public college in an introductory physics course for non-science majors. Twenty-three students of diverse gender, race, ethnic, immigrant and class backgrounds enrolled. I conducted an ethnography of the classroom to learn how students negotiate their subjectivities to affiliate with or alienate from their perceptions of physics, and to understand how classroom experiences exacerbate or

Students leaving their hometown and family at a young age to pursue better educational opportunities overseas are confronted with life adjustment stress, which in turn affects their mental health and academic performance. This study aimed to examine the relationships among stress, coping strategies, and depressive symptoms using the stress coping framework in overseas Chinese university preparatory students in Taiwan. Methods A cross-sectional study was conducted at an overseas Chinese university preparatory institute in Taiwan. Of enrolled overseas Chinese university preparatory students at 2009, 756 completed a structured questionnaire measuring stress, strategies for coping with it, and the Center for Epidemiologic Studies Depression Scale. Results High levels of stress significantly predicted the adoption of active, problem-focused coping strategies (R2 = 0.13, p R2 = 0.24, p z = 8.06, p Conclusion Our study results suggested that stress is associated with coping strategies and depressive symptoms and passive strategies mediate the relation between stress and depressive symptoms in overseas Chinese university preparatory students.

Mapping cognitive structures of community college students engaged in basic electrostatics laboratories

Science.gov (United States)

Haggerty, Dennis Charles

Community college students need to be abstract thinkers in order to be successful in the introductory Physics curriculum. The purpose of this dissertation is to map the abstract thinking of community college Physics students. The laboratory environment was used as a vehicle for the mapping. Three laboratory experiments were encountered. One laboratory was based on the classic Piagetian task, the centripetal motion (CM) problem. The other two laboratories were introductory electrostatic Physics experiments, Resistance (RES) and Capacitance (CAP). The students performed all laboratories using the thinking-aloud technique. The researcher collected their verbal protocols using audiotapes. The audiotaped data was quantified by comparing it to a scoring matrix based on the Piagetian logical operators (Inhelder & Piaget, 1958) for abstract thinking. The students received scores for each laboratory experiment. These scores were compared to a reliable test of intellectual functioning, the Shipley Institute of Living Scale (SILS). Spearman rank correlation coefficients (SRCC) were obtained for SILS versus CM; SILS versus RES; and SILS versus CAP. Statistically significant results were obtained for SILS versus CM and SILS versus RES at the p < 0.05 level. When an outlier to the data was considered and suppressed, the SILS versus CAP was also statistically significant at the p < 0.05 level. The scoring matrix permits a bridge from the qualitative Piagetian level of cognitive development to a quantified, mapped level of cognitive development. The ability to quantify student abstract thinking in Physics education provides a means to adjust an instructional approach. This approach could lead to a proper state of Physics education.

Full Text Available Background: Most students admitted to medical school are abstract-passive learners. However, as they progress through the program, active learning and concrete interpersonal interactions become crucial for the acquisition of professional competencies. The purpose of this study was to determine if and how medical students' learning styles change during the course of their undergraduate program. Methods: All students admitted to the Pontificia Universidad Católica de Chile (PUC medical school between 2000 and 2011 (n = 1,290 took the Kolb’s Learning Style Inventory at school entrance. Two years later 627 students took it again, and in the seventh and last year of the program 104 students took it for a third time. The distribution of styles at years 1, 3 and 7, and the mobility of students between styles were analyzed with Bayesian models. Results: Most freshmen (54% were classified as assimilators (abstract-passive learners; convergers (abstract-active followed with 26%, whereas divergers (concrete-passive and accommodators (concrete-active accounted for 11% and 9%, respectively. By year 3, the styles' distribution remained unchanged but in year 7 convergers outnumbered assimilators (49% vs. 33%. In general, there were no gender-related differences. Discussion: Medical students change their preferred way of learning: they evolve from an abstract-reflexive style to an abstract-active one. This change might represent an adaptation to the curriculum, which evolves from a lecture-based teacher-centered to a problem-based student–centered model.

Halper, Michael; Gu, Huanying; Perl, Yehoshua; Ochs, Christopher

2015-05-01

Terminologies and terminological systems have assumed important roles in many medical information processing environments, giving rise to the "big knowledge" challenge when terminological content comprises tens of thousands to millions of concepts arranged in a tangled web of relationships. Use and maintenance of knowledge structures on that scale can be daunting. The notion of abstraction network is presented as a means of facilitating the usability, comprehensibility, visualization, and quality assurance of terminologies. An abstraction network overlays a terminology's underlying network structure at a higher level of abstraction. In particular, it provides a more compact view of the terminology's content, avoiding the display of minutiae. General abstraction network characteristics are discussed. Moreover, the notion of meta-abstraction network, existing at an even higher level of abstraction than a typical abstraction network, is described for cases where even the abstraction network itself represents a case of "big knowledge." Various features in the design of abstraction networks are demonstrated in a methodological survey of some existing abstraction networks previously developed and deployed for a variety of terminologies. The applicability of the general abstraction-network framework is shown through use-cases of various terminologies, including the Systematized Nomenclature of Medicine - Clinical Terms (SNOMED CT), the Medical Entities Dictionary (MED), and the Unified Medical Language System (UMLS). Important characteristics of the surveyed abstraction networks are provided, e.g., the magnitude of the respective size reduction referred to as the abstraction ratio. Specific benefits of these alternative terminology-network views, particularly their use in terminology quality assurance, are discussed. Examples of meta-abstraction networks are presented. The "big knowledge" challenge constitutes the use and maintenance of terminological structures that

Text-based communication is one of the substantial ways of spreading scientific information. While the content and contextual aspects of written words have been widely researched, the impact of font characteristics on text perception is an almost blank page. The following study deals with the influence of serifs on the evaluation of online-presented scientific abstracts. Yet there is only evidence for faster reading times when texts are presented in sans-serif fonts, although the opposite is stated in parts of the literature. The present work examines if the presence or absence of serifs also have an impact on the appraisal of scientific texts when all other important font characteristics do not change. For this purpose, 188 university students participated in an online experiment and rated different aspects of scientific abstracts as well as of the research outlined in the abstracts. The results show that missing serifs led to increased reading speed. However, and in contrast to the perceptual fluency hypothesis, the presence of serifs had a positive effect on all evaluation dimensions. The results of a second study with 187 participants also indicated that reading fluency counteracted the liking of texts. Implications for future studies and media production are discussed. © 2015 International Union of Psychological Science.

Full Text Available Abstract The social conduct of an individual comprises all the interpersonal behaviors that he or she exhibits in the social contexts he or she is exposed to. The Social Conduct Scale (SCS is a self-report instrument developed to provide researchers and clinicians with information on prosocial, antisocial and oppositional-defiant tendencies of Portuguese-speaking children and adolescents. In the present study, we conducted an analysis of the criterion validity of the SCS by comparing the scores obtained from a large population-based sample (N= 1,172 against an offender (N= 129, a scholar (N= 31, and a clinic-referred (N= 24 sample of adolescents with marked previous conduct problems. As expected, antisocial youths had significantly higher means on antisocial behaviors and lower means on prosocial tendencies when compared to the population-based sample. Overall, findings supported the hypothesized criterion validity of the SCS. The instrument might play a role as a helpful resource for researchers, clinicians and practitioners interested in assessing the social conduct of Brazilian children and adolescents.

Frontopolar cortex mediates abstract integration in analogy.

Green, Adam E; Fugelsang, Jonathan A; Kraemer, David J M; Shamosh, Noah A; Dunbar, Kevin N

2006-06-22

Integration of abstractly similar relations during analogical reasoning was investigated using functional magnetic resonance imaging. Activation elicited by an analogical reasoning task that required both complex working memory and integration of abstractly similar relations was compared to activation elicited by a non-analogical task that required complex working memory in the absence of abstract relational integration. A left-sided region of the frontal pole of the brain (BA 9/10) was selectively active for the abstract relational integration component of analogical reasoning. Analogical reasoning also engaged a left-sided network of parieto-frontal regions. Activity in this network during analogical reasoning is hypothesized to reflect categorical alignment of individual component terms that make up analogies. This parieto-frontal network was also engaged by the complex control task, which involved explicit categorization, but not by a simpler control task, which did not involve categorization. We hypothesize that frontopolar cortex mediates abstract relational integration in complex reasoning while parieto-frontal regions mediate working memory processes, including manipulation of terms for the purpose of categorical alignment, that facilitate this integration.

Abstract Purpose To determine the self-concepts of chiropractic students as science students and if any personal variable affect their self-concepts. Participants Students in their first trimester and eighth trimester at the Los Angeles College of Chiropractic during the 1993 academic year (n=158). Methods Peterson-Yaakobi Q-Sort, National Assessment of Educational Progress, two-tailed T-test, one way analysis of variance and Spearman-rho correlation. Results The majority of students have positive self- concepts as science students and although there was a difference between the 2 trimesters, it was not significant. As a group they generally had less exposure to science compared to undergraduates from a selected science program. Variables of socio-economic status, undergraduate major, and highest completed level of education did not statistically affect their self-concept. Conclusion Chiropractic students had the self-concept that enables them to subscribe to the philosophical foundations of science and better engage in basic sciences and, later, science-based clinical research. Knowledge of this self- concept can be used in the development of a more rigorous basic science curricula and clinical research programs at chiropractic colleges with the ultimate goal of providing a more firm scientifically based foundation for the profession.

THE IMPACT OF MULTIMEDIA PRESENTATIONS ON SCIENCE LEARNING Peter G. Schrader University of Nevada Las Vegas, USA pg.schrader@unlv.edu Eric E. Rapp ericrapp@icloud.com ABSTRACT In K-12 school settings in the United States, there is a preponderance of information delivered via multimedia to students everyday (e.g., visual aids found in science textbooks, electronic tablets, streamed video content, web pages, animations, and PowerPoint presentations. The cognitive theory of multimedia learning (CTML outlines numerous principles associated with learning from and with multimedia (Mayer, Hegarty, Mayer, & Cambell, 2005. However, the bulk of the research like the CTML has been conducted using college age students (Jones, 2010; McTigue, 2009. There is ample evidence that college age students and younger students exhibit numerous and important differences when learning from multimedia content (Hannus & Hyona, 1999; McTique, 2009; Moreno, 2007; Van Parreren, 1983.

The present study investigates whether scientific abstracts, which were accepted for presentation at the annual meeting of the German Cardiac Society (DGK) will be published more frequently and with higher ranking than rejected abstracts. Additionally, we analyzed whether the current peer review process of the congress abstracts is able to identify research of high quality. All abstracts submitted for the DGK meetings between 2006 and 2010 were anonymized and graded by 5-9 reviewers. Based on these ratings, abstracts were accepted or rejected. A Medline search with name of the first author, key words and content of all abstracts was conducted to identify publications following the congress abstracts. In case of identification of a publication, the impact factor (IF) of the journal was assessed. 5535 (66 %) of 8411 submitted abstracts were accepted for presentation (basic reseach: 2497; clinical study: 5914). A total of 23 % of all abstracts were published (IF 3.6). The average time to publication was 0.7 ± 1.2 years, while 35 % of all published studies achieved publication in the year of congress. The publication rate was 26 % for accepted abstracts (IF 3.8) and 17 % (2.4) for rejected abstracts. Basic research achieved higher publication rates than clinical studies (26 % vs. 21 %) and had a higher average impact factor (IF 5.1 vs. 3). The present study shows that abstracts, which were accepted for presentation achieved a publication more frequently and in higher-ranked journals than rejected abstracts. © Georg Thieme Verlag KG Stuttgart · New York.

Shamoo, Adil E

2015-01-01

Since the early 2000s, the field of Responsible Conduct of Research has become widely recognized as essential to scientific education, investigation, and training. At present, research institutions with public funding are expected to have some minimal training and education in RCR for their graduate students, fellows and trainees. These institutions also are expected to have a system in place for investigating and reporting misconduct in research or violations of regulations in research with human subjects, or in their applications to federal agencies for funding. Public scrutiny of the conduct of scientific researchers remains high. Media reports of misconduct scandals, biased research, violations of human research ethics rules, and moral controversies in research occur on a weekly basis. Since the 2009 publication of the 2nd edition of Shamoo and Resnik's Responsible Conduct of Research, there has been a vast expansion in the information, knowledge, methods, and diagnosis of problems related to RCR and the ...

Full Text Available Abstract Background HIV testing and counseling (HTC with linkage to care after known infection are key components for HIV transmission prevention. This study was conducted to assess HTC uptake, HIV risk perception and linkage to care among Thai university students. Methods An outreach HTC program was conducted in a large public university in Thailand from January 2013 to December 2014. The program consisted of brief HIV knowledge assessment, free HTC, HIV risk assessment and education provided by the healthcare personnel. Students were categorized into low, moderate and high-risk groups according to the pre-defined HIV risk characteristics. Results One-thousand-eight-hundred-one students participated in the program, 494 (27 % underwent HTC. Independent characteristics associated with no HTC uptake included female sex (P < 0.001, lower HIV knowledge score (P < 0.001, younger age (P < 0.001 and students from non-health science faculties (P = 0.02. Among the 494 students undergoing HTC, 141 (29 % were categorized into moderate or high-risk group, of whom 45/141 (32 % had false perception of low HIV risk. Being heterosexual was independently associated with false perception of low HIV risk (P = 0.04. The rate of new HIV infection diagnosis was 4/494 (0.8 %. Of these 4 HIV-infected students, 3 (75 % were men who have sex with men and only 2 of the 4 students (50 % showed up for HIV continuity care. Conclusions An outreach HIV prevention program with HTC was feasible and beneficial in detecting HIV risk and infection among the university students. However, interventions to improve HTC uptake, HIV risk perception and linkage to care are needed.

Students in OU's Geology and Geophysics (G&G) program must complete either English Technical Writing or a major-specific Geowriting class as sophomores or juniors. We asked students in Geowriting and students in a G&G colloquium course (required for G&G scholarship students and an elective for others) to complete surveys reporting their writing experiences and attitudes, as well as write an abstract for a Scientific American story to assess writing skills at the beginning and end of the semester. Geowriting students had stronger writing skills and more positive attitudes towards writing at the beginning of the semester than their colloquium peers, suggesting that students who were already interested and skilled in writing were self-selecting into the class. During the semester, Geowriting focused on improving the clarity, organization, efficiency, and mechanics of student writing and discussed how science writing is similar in some ways (argument, sentence structure, etc.), but also different in many aspects (concise, forthright, repetitive, etc) from writing tactics taught in high school and some college composition courses. Colloquium students attended the weekly scientific talks, but did not write in the class; however, some students were enrolled in freshman-level composition courses and Technical Writing. End-of-semester surveys showed Geowriting students had a more positive change in attitude and expectations towards writing than their colloquium peers. However, one significant difference in attitude towards writing was indicated by negative feelings towards in-class writing, which may be a result of 'writing fatigue' within the Geowriting group. This writing fatigue could be explained by student end-of -semester cognitive overload. Through other measures, colloquium students showed a greater improvement in writing skills (concise, clear, organized, etc) compared to Geowriting students; however, Geowriting students maintained higher skill levels than the

To determine whether a school-wide intervention program to reduce risk factors for type 2 diabetes (T2D) affected student achievement, rates of disciplinary actions, and attendance rates. The HEALTHY primary prevention trial was designed to evaluate a comprehensive school-based intervention to reduce factors for T2D, especially overweight and obesity. Students were followed up from beginning of sixth grade (Fall 2006) through end of eighth grade (Spring 2009). Forty-two middle schools at seven U.S. sites. Schools were randomized in equal numbers at each site to intervention (21 schools, 2307 students) or control (21 schools, 2296 students). Intervention . An integrated school-wide program that focused on (1) foods and beverages, (2) physical education, (3) classroom-based behavior change and education, and (4) social marketing communication and promotional campaigns. Aggregate (grade- and school-wide) test performance (passing rate), attendance, and referrals for disciplinary actions. Descriptive statistics and tests of intervention versus control using mixed linear models methods to adjust for the clustering of students within schools. There were no differences between intervention and control schools in test performance for mathematics (p = .7835) or reading (p = .6387), attendance (p = .5819), or referrals for disciplinary action (p = .8671). The comprehensive HEALTHY intervention and associated research procedures did not negatively impact student achievement test scores, attendance, or referrals for disciplinary action.

Full Text Available Abstract Background The evidence base for mental illness related stigma interventions in health care professionals and trainees is underdeveloped. This study aimed to examine the impact of mental illness related stigma training on third year medical students' knowledge, attitudes and behaviour related to people with mental illness. Methods A non-randomised controlled trial was conducted with 110 third year medical students at a medical school in England to determine the effectiveness of a mental illness related stigma training package that targeted their knowledge, attitudes and behaviour. Results We detected a significant positive effect of factual content and personal testimonies training upon an improvement in knowledge, F(1, 61 = 16.3, p = 0.0002. No such difference was determined with attitudes or for behaviour. Conclusions Knowledge, attitudes and behaviour may need to be separately targeted in stigma reduction interventions, and separately assessed. The inter-relationships between these components in mental health promotion and medical education warrant further research. The study next needs to be replicated with larger, representative samples using appropriate evaluation instruments. More intensive training for medical students may also be required.

2012-05-01

Full Text Available Abstract Background Self-medication is the use of medication without prescription, orientation, or supervision of a physician or dentist. Self-medication might become a serious health problem. The purpose of this study was to identify the prevalence and factors associated with self-medication among first and last-year students enrolled in healthcare and non-healthcare programs. Methods A cross-sectional study was conducted at Universidade Federal do Rio Grande (FURG, state of Rio Grande do Sul, Brazil. Of 830 students in the sample, 95% answered the questionnaire – 789 students enrolled in 10 undergraduate programs. Mean age was 22 ± 6.17 years. The students answered a questionnaire covering socio-economic and demographic variables, use of medication, and medication knowledge. Information was collected on the conditions treated with medication, the medications used, and attitude towards self-medication. Results Of 789 students, 86.4% self-medicated (88.5% of 446 healthcare students. There were no significant differences in self-medication between healthcare and non-healthcare students, nor between first and last-year students. Bivariate and multivariate analyses showed a significant association between self-medication and having children (p = 0.01, having a home pharmacy (p p = 0.01. The most frequently used active ingredients were acetaminophen (paracetamol, dipyrone, aspirin, phytotherapic compounds, and tea. Illicit drug use was significantly associated with self-medication in the multivariate analysis. Conclusion The fact that being a healthcare student was associated with higher medication knowledge, but not with less self-medication, suggests that medication knowledge might contribute to increase self-medication. This should be taken into account when designing educational interventions relating to self-medication.

This Analysis/Model Report (AMR) describes an abstraction, for the performance assessment total system model, of the near-field host rock water chemistry and gas-phase composition. It also provides an abstracted process model analysis of potentially important differences in the thermal hydrologic (TH) variables used to describe the performance of a geologic repository obtained from models that include fully coupled reactive transport with thermal hydrology and those that include thermal hydrology alone. Specifically, the motivation of the process-level model comparison between fully coupled thermal-hydrologic-chemical (THC) and thermal-hydrologic-only (TH-only) is to provide the necessary justification as to why the in-drift thermodynamic environment and the near-field host rock percolation flux, the essential TH variables used to describe the performance of a geologic repository, can be obtained using a TH-only model and applied directly into a TSPA abstraction without recourse to a fully coupled reactive transport model. Abstraction as used in the context of this AMR refers to an extraction of essential data or information from the process-level model. The abstraction analysis reproduces and bounds the results of the underlying detailed process-level model. The primary purpose of this AMR is to abstract the results of the fully-coupled, THC model (CRWMS M andO 2000a) for effects on water and gas-phase composition adjacent to the drift wall (in the near-field host rock). It is assumed that drift wall fracture water and gas compositions may enter the emplacement drift before, during, and after the heating period. The heating period includes both the preclosure, in which the repository drifts are ventilated, and the postclosure periods, with backfill and drip shield emplacement at the time of repository closure. Although the preclosure period (50 years) is included in the process models, the postclosure performance assessment starts at the end of this initial period

An experimental apparatus was designed and built to allow students to carry out heat conduction experiments in hollow cylinders made of different materials, as well as to determine the thermal conductivity of these materials. The evolution of the temperature difference between the inner and outer walls of the cylinder as a function of time is analysed, and when the process reaches the steady state regime the thermal conductivity can be easily calculated. Several materials such as wood, plastic and metals are considered and the values of their thermal conductivities, obtained experimentally, are compared with those given in the reference list.

Writing business research article abstracts: A genre approach

Directory of Open Access Journals (Sweden)

Carmen Piqué-Noguera

2012-10-01

Full Text Available A great deal has been published about oral and written genres in business (e.g., letters, research articles, oral presentations, etc., and less attention has been paid to business research article abstracts as a written genre, as many experts would argue. This research intends to raise rhetorical awareness about the role of abstracts in today’s academic world. To this effect, the abstracts of two official publications of the Association of Business Communication, Journal of Business Communication and Business Communication Quarterly, have been analyzed and compared in terms of structure and content according to models published in the specialized literature. The results show an irregular and inconsistent presentation of abstracts, a good number of them following no set pattern and thus lacking in important information for researchers. These findings suggest, first of all, that abstracts have a specific mission to fulfil and should not be disregarded; and, secondly, that journal guidelines for authors should be more explicit in their instructions on how to write and structure abstracts.

We bridge the gap between functional evaluators and abstract machines for the λ-calculus, using closure conversion, transformation into continuation-passing style, and defunctionalization.We illustrate this approach by deriving Krivine's abstract machine from an ordinary call-by-name evaluator...... and by deriving an ordinary call-by-value evaluator from Felleisen et al.'s CEK machine. The first derivation is strikingly simpler than what can be found in the literature. The second one is new. Together, they show that Krivine's abstract machine and the CEK machine correspond to the call-by-name and call...

Since 2014, the Exploration of the Moon and Asteroids by Secondary Students, or ExMASS, program provides an opportunity for students to participate in authentic scientific research. The ExMASS program is an effort managed by the Center for Lunar Science and Exploration (CLSE). Led by the Lunar and Planetary Institute and Johnson Space Center, CLSE is one of nine teams comprising NASA's Solar System Exploration Research Virtual Institute (SSERVI). Over the course of one academic year, 10 teams of U.S. high school students conduct their own scientific investigations of Earth's Moon, or asteroids, with guidance from a scientist advisor. The program includes two elements: 1) two guided-inquiry introductory research activities that builds student knowledge of current lunar/asteroid science and lunar/asteroid data, and 2) an open-inquiry research project in which the students apply their knowledge to a self-defined project. Because the research is student-driven, it is not necessarily original research; original research is therefore not required. However, one team's research has been published in a professional journal. At the end of the school year, teams submit an abstract and research poster which are scored by a panel a judges. The top four scoring teams gather virtually to give short presentations to the judges. After presentations and time for Q&A, the judges choose one team to present in person at the Exploration Science Forum (ESF). The posters of all finalist schools are displayed at the ESF. The ExMASS program is evaluated by collecting data on changes in students' lunar/asteroid content knowledge, student attitudes toward science and science careers, and student perceptions of the processes of science in which their team participated. Exit surveys for teachers, students, and advisors are also distributed at the end of each program year to gather general feedback about the program and its impact. Results of this data from the first two years of the Ex

In Public Health, a thorough review of abstract quality evaluations and the publication history of studies presented at scientific meetings has never been conducted. To analyse the long-term outcome of quality abstracts submitted to conferences of Italian Society of Hygiene and Public Health (SItI) from 2005 to 2007, we conducted a second analysis of previously published material aiming to estimate full-text publication rate of high quality abstract presented at Italian public health meetings, and to identify predictors of full-text publication. The search was undertaken through scientific databases and search engines and through the web sites of the major Italian journals of Public Health. For each publication confirmed as a full text paper, the journal name, impact factor, year of publication, gender of the first author, type of study design, characteristics of the results and sample size were collected. The overall publication rate of the abstracts presented is 23.5%; most of the papers were published in Public Health journals (average impact factor: 3.007). Non universitary affiliation had resulted in a lower probability of publication, while some of the Conference topics had predisposed the studies to an increased likelihood of publication as well as poster form presentation. The method presented in this study provides a good framework for the evaluation of the scientific evidence. The findings achieved should be taken into consideration by the Scientific Societies during the contributions selection phase, with the aim of achieving a continuous improvement of work quality. In the future, it would be interesting to survey the abstract authors to identify reasons for unpublished data.

2015-04-01

The purpose of the study was to investigate the effects of research-article writing motivation and use of self-regulatory writing strategies in explaining second language (L2) research-article abstract writing ability, alongside the L2 literacy effect. Four measures were administered: a L2 literacy test, a research abstract performance assessment, and inventories of writing motivation and strategy. Participants were L2 graduate students in Taiwan (N=185; M age=25.8 yr., SD=4.5, range=22-53). Results of structural equation modeling showed a direct effect of motivation on research-article writing ability, but no direct effect of strategy or indirect effect of motivation via strategy on research-article writing ability, with L2 literacy controlled. The findings suggest research-article writing instruction should address writing motivation, besides L2 literacy.

Full Text Available Abstract Background An ongoing evaluation system is essential to determine if the academic system in place has worked to produce a better product, hence the objective of our study was to evaluate the satisfaction level among medical students regarding their academic teaching and assessment method and what measures will they suggest for the future to rectify the current situation. This questionnaire based cross sectional study was conducted in a public sector medical university from February to July 2010. A well structured questionnaire was administered to a random sample of 375 final year medical students. However 292 of the students provided informed consent and filled in the questionnaire which included their demographic profile as well as questions in line with the study objective. Data was entered in a Statistical Package for Social Sciences (SPSS version.16 and analyzed using descriptive statistics. Findings The male to female ratio in our study was 1:2. Most of the students (57.2% were dissatisfied with the quality of teaching in the university. Fifty-seven percent of the participants believed that the current standard of their institute were not at par with those of international medical universities. BCQ's were the mode of examination questions preferred by the majority of the students. Most of the students (66.1% wanted the university to conduct career planning seminars to help them plan their career. Conclusions These results suggest that the students of public sector medical universities are unsatisfied from current academic facilities and teaching activities. Students recommend increased emphasis on better lectures and practical training as well as a need to incorporate career planning sessions for the students to help plan them their future career paths.

The university and the responsible conduct of research: who is responsible for what?

Science.gov (United States)

Alfredo, Katherine; Hart, Hillary

2011-09-01

Research misconduct has been thoroughly discussed in the literature, but mainly in terms of definitions and prescriptions for proper conduct. Even when case studies are cited, they are generally used as a repository of "lessons learned." What has been lacking from this conversation is how the lessons of responsible conduct of research are imparted in the first place to graduate students, especially those in technical fields such as engineering. Nor has there been much conversation about who is responsible for what in training students in Responsible Conduct of Research or in allocating blame in cases of misconduct. This paper explores three seemingly disparate cases of misconduct-the 2004 plagiarism scandal at Ohio University; the famous Robert Millikan article of 1913, in which his reported data selection did not match his notebooks; and the 1990 fabrication scandal in Dr. Leroy Hood's research lab. Comparing these cases provides a way to look at the relationship between the graduate student (or trainee) and his/her advisor (a relationship that has been shown to be the most influential one for the student) as well as at possibly differential treatment for established researchers and researchers-in-training, in cases of misconduct. This paper reflects on the rights and responsibilities of research advisers and their students and offers suggestions for clarifying both those responsibilities and the particularly murky areas of research-conduct guidelines.

EBS Radionuclide Transport Abstraction

2005-01-01

The purpose of this report is to develop and analyze the engineered barrier system (EBS) radionuclide transport abstraction model, consistent with Level I and Level II model validation, as identified in ''Technical Work Plan for: Near-Field Environment and Transport: Engineered Barrier System: Radionuclide Transport Abstraction Model Report Integration'' (BSC 2005 [DIRS 173617]). The EBS radionuclide transport abstraction (or EBS RT Abstraction) is the conceptual model used in the total system performance assessment for the license application (TSPA-LA) to determine the rate of radionuclide releases from the EBS to the unsaturated zone (UZ). The EBS RT Abstraction conceptual model consists of two main components: a flow model and a transport model. Both models are developed mathematically from first principles in order to show explicitly what assumptions, simplifications, and approximations are incorporated into the models used in the TSPA-LA. The flow model defines the pathways for water flow in the EBS and specifies how the flow rate is computed in each pathway. Input to this model includes the seepage flux into a drift. The seepage flux is potentially split by the drip shield, with some (or all) of the flux being diverted by the drip shield and some passing through breaches in the drip shield that might result from corrosion or seismic damage. The flux through drip shield breaches is potentially split by the waste package, with some (or all) of the flux being diverted by the waste package and some passing through waste package breaches that might result from corrosion or seismic damage. Neither the drip shield nor the waste package survives an igneous intrusion, so the flux splitting submodel is not used in the igneous scenario class. The flow model is validated in an independent model validation technical review. The drip shield and waste package flux splitting algorithms are developed and validated using experimental data.

Full Text Available ABSTRACT The current study aimed to identify and analyze the prevalence of ethical conflicts experienced by medical students. This study is a cross-sectional and analytical research that was conducted in a public school in the state of Minas Gerais, Brazil. The instrument used for the data collection was a self-administered questionnaire. The data collected were presented in absolute and percentage values. For the analytical statistical treatment of the data, the level of significance was considered p <0.05. The outcome variables were: Experiences of ethical conflicts in interpersonal relations within the medical course and Ethical conduct in health care. The identification of the prevalence of ethical conflicts in the undergraduate program adopted the perspective of different interpersonal relations (academic-teaching, academic-academic, academic-employee, academic-patient, teacher-teacher, teacher-patient, teacher-employee and employee-patient. (Importance of identifying themselves to the health services user and requesting consent to perform the physical examination, assistance without the supervision of the teacher, issuance of health documents without the signature of the professional responsible and use of social networks to share data Of patient. It was verified the association of the outcome variables with sex, year of graduation and course evaluation.

Academic freedom, analysis, and the Code of Professional Conduct.

Science.gov (United States)

Snelling, Paul C; Lipscomb, Martin

2004-11-01

Despite nursing's move into higher education, academic freedom has received little attention within the literature. After discussing the concept of academic freedom, this paper argues that there is a potential tension between academic freedom and the requirement to educate student nurses who are fit for practice. One way in which this tension might be revealed is in the marking of student assignments. We ask the question--how should nurse educators mark an essay which is sufficiently analytical but reaches moral conclusions that lie outside the Code of Professional Conduct? We argue that despite an understandable temptation to penalise such an essay, invoking the Code of Professional Conduct to do so, no penalty should be applied, and academic freedom for students within higher education should be encouraged. This is because first, academic freedom is a good in itself especially as it allows unconventional and unpalatable conclusions to be discussed and rebutted, and second, applying a penalty on these grounds is necessarily inconsistent.

2007-09-01

Full Text Available Abstract Background School-based breakfast provision is increasingly being seen as a means of improving educational performance and dietary behaviour amongst children. Furthermore, recognition is growing that breakfast provision offers potential as a means of addressing social inequalities in these outcomes. At present however, the evidence base on the effectiveness of breakfast provision in bringing about these improvements is limited. Methods/Design This paper describes the research design of a large scale evaluation of the effectiveness of the Welsh Assembly Government's Primary School Free Breakfast Initiative. A cluster randomised trial, with school as the unit of randomisation was used for the outcome evaluation, with a nested qualitative process evaluation. Quantitative outcome measures included dietary habits, attitudes, cognitive function, classroom behaviour, and school attendance. The study recruited 111 primary schools in Wales, of which 56 were randomly assigned to control condition and 55 to intervention. Participants were Year 5 and 6 students (aged 9–11 years in these schools. Data were collected for all 111 schools at each of three time points: baseline, 4 month and 12 month follow-up. This was achieved through a repeated cross-sectional survey of approximately 4350 students on each of these occasions. Of those students in Year 5 at baseline, 1975 provided data at one or both of the follow-ups, forming a nested cohort. The evaluation also included a nested process evaluation, using questionnaires, semi-structured interviews and case studies with students, school staff, and local authority scheme coordinators as key informants. Discussion An overview of the methods used for the evaluation is presented, providing an example of the feasibility of conducting robust evaluations of policy initiatives using a randomised trial design with nested process evaluation.

A study of understanding: Alchemy, abstraction, and circulating reference in tertiary science education

Science.gov (United States)

Merritt, Brett W.

Understanding is widely touted to be of paramount importance for education. This is especially true in science education research and development where understanding is heralded as one of the cornerstones of reform. Teachers are expected to teach for understanding and students are expected to learn with understanding. This dissertation is an empirical study of the concept of understanding. After analyzing various constructions of understanding in current U.S. education literature, I suggest that understanding is defined by five distinct features---they are knowledge (or knowledge base), coherence, transfer, extrapolation, and cognition--- and that these features are heavily informed and shaped by the psychological sciences. This relationship is neither good nor bad, I argue, but it means that teaching for and learning with understanding are not heavily informed and shaped by, for example, the natural sciences. Drawing from historical, philosophical, and anthropological perspectives of science, but especially from the work of Bruno Latour, I enact a radical revision(ing) of psychological notions such as "abstraction" and "transfer." The two main purposes of this re-visioning are (1) to draw critical attention to particular characteristics of a cognitive learning theory that emphasizes abstract concepts, and (2) to align many of the principles and tools used in science education more closely with those used in empirical scientific research. Finally, by bringing some examples of teaching and learning from an undergraduate biology classroom into conversation with both psychological and empirical practices and perspectives, I suggest that problematizing the current construction of understanding creates much needed room in mainstream science education for more empirical forms of learning and styles of teaching. A shift to such forms and styles, I conclude, should prove to be more inclusive and less constraining for both students and teachers.

This study aims to classify abstract content based on the use of the highest number of words in an abstract content of the English language journals. This research uses a system of text mining technology that extracts text data to search information from a set of documents. Abstract content of 120 data downloaded at www.computer.org. Data grouping consists of three categories: DM (Data Mining), ITS (Intelligent Transport System) and MM (Multimedia). Systems built using naive bayes algorithms to classify abstract journals and feature selection processes using term weighting to give weight to each word. Dimensional reduction techniques to reduce the dimensions of word counts rarely appear in each document based on dimensional reduction test parameters of 10% -90% of 5.344 words. The performance of the classification system is tested by using the Confusion Matrix based on comparative test data and test data. The results showed that the best classification results were obtained during the 75% training data test and 25% test data from the total data. Accuracy rates for categories of DM, ITS and MM were 100%, 100%, 86%. respectively with dimension reduction parameters of 30% and the value of learning rate between 0.1-0.5.

Full Text Available According to the dual coding theory, differences in the ease of retrieval between concrete and abstract words are related to the exclusive dependence of abstract semantics on linguistic information. Argument structure can be considered a measure of the complexity of the linguistic contexts that accompany a verb. If the retrieval of abstract verbs relies more on the linguistic codes they are associated to, we could expect a larger effect of argument structure for the processing of abstract verbs. In this study, sets of length- and frequency-matched verbs including 40 intransitive verbs, 40 transitive verbs taking simple complements, and 40 transitive verbs taking sentential complements were presented in separate lexical and grammatical decision tasks. Half of the verbs were concrete and half were abstract. Similar results were obtained in the two tasks, with significant effects of imageability and transitivity. However, the interaction between these two variables was not significant. These results conflict with hypotheses assuming a stronger reliance of abstract semantics on linguistic codes. In contrast, our data are in line with theories that link the ease of retrieval with availability and robustness of semantic information.

To identify the student's readiness to perform self-directed learning and the underlying factors influencing it on the hybrid problem based learning curriculum. A combination of quantitative and qualitative studies was conducted in five medical schools in Indonesia. In the quantitative study, the Self Directed Learning Readiness Scale was distributed to all students in all batches, who had experience with the hybrid problem based curriculum. They were categorized into low- and high -level based on the score of the questionnaire. Three focus group discussions (low-, high-, and mixed level) were conducted in the qualitative study with six to twelve students chosen randomly from each group to find the factors influencing their self-directed learning readiness. Two researchers analysed the qualitative data as a measure of triangulation. The quantitative study showed only half of the students had a high-level of self-directed learning readiness, and a similar trend also occurred in each batch. The proportion of students with a high level of self-directed learning readiness was lower in the senior students compared to more junior students. The qualitative study showed that problem based learning processes, assessments, learning environment, students' life styles, students' perceptions of the topics, and mood, were factors influencing their self-directed learning. A hybrid problem based curriculum may not fully affect the students' self-directed learning. The curriculum system, teacher's experiences, student's background and cultural factors might contribute to the difficulties for the student's in conducting self-directed learning.

DENOTATIVE ORIGINS OF ABSTRACT IMAGES IN LINGUISTIC EXPERIMENT

Directory of Open Access Journals (Sweden)

Elina, E.

2017-03-01

Full Text Available The article discusses the refusal from denotation (the subject, as the basic principle of abstract images, and semiotic problems arising in connection with this principle: how to solve the contradiction between the pointlessness and iconic nature of the image? Is it correct in the absence of denotation to recognize abstract representation of a single-level entity? The solution is proposed to decide these questions with the help of a psycholinguistic experiment in which the verbal interpretation of abstract images made by both experienced and “naive” audience-recipients demonstrates the objectivity of perception of denotative “traces” and the presence of denotative invariant in an abstract form.

6.        Uniwersytet Mikołaja Kopernika w Toruniu   Słowa kluczowe: zachowania zdrowotne, studenci. Key words: health behaviors, students.     Streszczenie Bardzo ważną rolę w procesie ochrony zdrowia jest styl życia człowieka – jego nawyki oraz wzorce postępowania. Celem badań była ocena zachowań zdrowotnych studentów kierunku Dietetyka. Grupę badawczą (Grupa I stanowiło 80 studentów kierunku Dietetyka. Grupę porównawczą (Grupa II stanowiło 70 studentów kierunków „niemedycznych” (kierunki inżynierskie. W grupie studentów Dietetyki uzyskano wysoki poziom zachowań zdrowotnych. Najwyższy poziom zachowań zdrowotnych uzyskano w kategorii „prawidłowe nawyki żywieniowe”. Studenci kierunku Dietetyka uzyskali wyższe wyniki zachowań zdrowotnych od studentów kierunków inżynierskich. Wprowadzanie programów promocji zdrowia i edukacji zdrowotnej powinno objąć wszystkie kierunki studiów, tym bardziej, że wczesna dorosłość jest najlepszym okresem dla osiągnięcia długotrwałych korzyści z wyboru zdrowego trybu życia.       Summary Very important role in the protection of health is a lifestyle - habits and patterns of conduct. The aim of the study was to assess health behaviors of Dietetics students. The research group (Group I conducted of 80 students of Dietetics. The control group (Group II conducted of 70 students of non-medical (in engineering. In the group of Dietetic student achieved a high level of health behaviors. The highest level of health behaviors was achieved in the category of "nutrition habits." Students of Dietetics scored higher health behavior of engineering students. Entering programs of health promotion and health education should be extended to all fields of study, especially that early adulthood is the best time to achieve long-term benefits of a healthy lifestyle choice.

Recently, the importance of effective maintenance in nuclear power plants (NPPs) has been emphasized and research into effective maintenance by adopting mobile maintenance aids (MMAs) have been attempted. For improved and effective use of an MMA display design method based on abstraction hierarchy (AH) is proposed and its design considerations are discussed in this study. Six levels of abstraction hierarchy are proposed in this paper to classify the maintenance information. By classifying and organizing maintenance information using AH, maintenance information can be used effectively by users with either high or low levels of expertise. When information classification has been finished, the information for MMA design is selected and designed. With the considerations of MMA design analysis and guidelines, AH-based MMA is designed for the maintenance tasks. An experiment is conducted using the AH-based MMA in order to estimate the effectiveness of the proposed method for the maintenance tasks and to identify design considerations to enhance the proposed MMAs. The result indicated that an AH-based manual was more effective than a conventional manual in terms of task completion time and number of errors. The workload for the AH-based manual was estimated less than the conventional manual for subjects with low level of expertise. As the level of expertise increases, subjects tended to follow more abstract information while the number of navigations decreased. It is believed that when mobile devices become pervasive in NPP maintenance fields, AH-model applied MMAs can be used as an effective maintenance supporting tool
