Yet many professors and administrators are boggled by the idea of playing academic games in college. They instantly dismiss faculty initiatives like "Reacting to the…

  11. Plato's Embryology.

    Science.gov (United States)

    Wilberding, James

    2015-01-01

    Embryology was a subject that inspired great cross-disciplinary discussion in antiquity, and Plato's Timaeus made an important contribution to this discussion, though Plato's precise views have remained a matter of controversy, especially regarding three key questions pertaining to the generation and nature of the seed: whether there is a female seed; what the nature of seed is; and whether the seed contains a preformed human being. In this paper I argue that Plato's positions on these three issues can be adequately determined, even if some other aspects of his theory cannot. In particular, it is argued that (i) Plato subscribes to the encephalo-myelogenic theory of seed, though he places particular emphasis on the soul being the true seed; (ii) Plato is a two-seed theorist, yet the female seed appears to make no contribution to reproduction; and (iii) Plato cannot be an advocate of preformationism.

  8. USING COMPUTER-BASED TESTING AS ALTERNATIVE ASSESSMENT METHOD OF STUDENT LEARNING IN DISTANCE EDUCATION

    Directory of Open Access Journals (Sweden)

    Amalia SAPRIATI

    2010-04-01

    Full Text Available This paper addresses the use of computer-based testing in distance education, based on the experience of Universitas Terbuka (UT, Indonesia. Computer-based testing has been developed at UT for reasons of meeting the specific needs of distance students as the following: Ø students’ inability to sit for the scheduled test, Ø conflicting test schedules, and Ø students’ flexibility to take examination to improve their grades. In 2004, UT initiated a pilot project in the development of system and program for computer-based testing method. Then in 2005 and 2006 tryouts in the use of computer-based testing methods were conducted in 7 Regional Offices that were considered as having sufficient supporting recourses. The results of the tryouts revealed that students were enthusiastic in taking computer-based tests and they expected that the test method would be provided by UT as alternative to the traditional paper and pencil test method. UT then implemented computer-based testing method in 6 and 12 Regional Offices in 2007 and 2008 respectively. The computer-based testing was administered in the city of the designated Regional Office and was supervised by the Regional Office staff. The development of the computer-based testing was initiated with conducting tests using computers in networked configuration. The system has been continually improved, and it currently uses devices linked to the internet or the World Wide Web. The construction of the test involves the generation and selection of the test items from the item bank collection of the UT Examination Center. Thus the combination of the selected items compromises the test specification. Currently UT has offered 250 courses involving the use of computer-based testing. Students expect that more courses are offered with computer-based testing in Regional Offices within easy access by students.

    2013-02-01

    There is a lack of educational material for adults with congenitally malformed hearts. Computer-based education has shown to have significant effects on knowledge and management of chronic diseases. The aim of this study was to develop and evaluate a computer-based educational program for adults with congenitally malformed hearts. The program was developed by a multidisciplinary team. Data were collected by questionnaires, observations, and structured interviews. The final product was a computer-based educational program consisting of ten separate modules, one for each particular malformation. The program was experienced as stimulating and easy to use. The appearance and quantity of the text was graded as good and the content as relevant and very useful. This is the first computer-based program developed for adults with congenitally malformed hearts. The evaluation found the program to have great potential as an important tool for improving care. Further studies are needed to test the outcomes of the program on knowledge, perceived control over the heart condition, anxiety/depression. and health-related quality of life. The program may be used as a complement to verbal information and every adult with a congenitally malformed hearts can receive individualized information from a personal CD.

    Mathov, Nicolás

    2016-05-01

    This work explores the links between the concepts of "soul", "law" and "word" in Plato's work, in order to highlight the importance and the centrality of the philosophical-therapeutic dimension in the Greek philosopher's thought. In that way, this work pretends to show that "contemporary" problems usually discussed within "Human Sciences" in general, and Psychiatry in particular, should confront their knowledge with Plato's work, mainly due to the profound influence his ideas have had in our Greco-Christian culture. In that sense, and with that objective, this work also explores Michel Foucault's lucid and controversial interpretation of Plato.

  7. Introducing Computer-Based Testing in High-Stakes Exams in Higher Education: Results of a Field Experiment.

    Directory of Open Access Journals (Sweden)

    Anja J Boevé

    Full Text Available The introduction of computer-based testing in high-stakes examining in higher education is developing rather slowly due to institutional barriers (the need of extra facilities, ensuring test security and teacher and student acceptance. From the existing literature it is unclear whether computer-based exams will result in similar results as paper-based exams and whether student acceptance can change as a result of administering computer-based exams. In this study, we compared results from a computer-based and paper-based exam in a sample of psychology students and found no differences in total scores across the two modes. Furthermore, we investigated student acceptance and change in acceptance of computer-based examining. After taking the computer-based exam, fifty percent of the students preferred paper-and-pencil exams over computer-based exams and about a quarter preferred a computer-based exam. We conclude that computer-based exam total scores are similar as paper-based exam scores, but that for the acceptance of high-stakes computer-based exams it is important that students practice and get familiar with this new mode of test administration.

  9. The Differences between Plato and Aristotle's Educational Philosophy%柏拉图与亚里士多德教育哲学的差异

    Institute of Scientific and Technical Information of China (English)

    刘良华

    2012-01-01

    古典西方教育哲学分为两个阵营:柏拉图以苏格拉底的名义组建他的“理想国”,按照“理论理性”设计他的“政治哲学”和教育方案;柏拉图坚持“哲人王”统治、公产制和道德教育。亚里士多德虽然坚持了哲学对政治的指导,但他看到了哲学对政治的危险,按照“实践理性”的优先性开创了不同于柏拉图的“政治哲学”的“政治科学”以及相关的教育方案。亚里士多德重视轮流制、私有制和法制教育。%The classical philosophy of education is divided into two camps. Plato built his Republic in the name of Socrates and designed the political philosophy and education plan with the theoretical reason. He adhered to the rule of the “philosophy king”, the communist membership system and moral education. Aristotle realized the danger of the philosophy to the politics, although he insisted in the guidance of philosophy to politics. He created the political science and education plan with the practical reason instead of Plato's political philosophy. He valued the political rule, the private ownership, and the legal education.

    Computer-based scaffolding assists students as they generate solutions to complex problems, goals, or tasks, helping increase and integrate their higher order skills in the process. However, despite decades of research on scaffolding in STEM (science, technology, engineering, and mathematics) education, no existing comprehensive meta-analysis has synthesized the results of these studies. This review addresses that need by synthesizing the results of 144 experimental studies (333 outcomes) on the effects of computer-based scaffolding designed to assist the full range of STEM learners (primary through adult education) as they navigated ill-structured, problem-centered curricula. Results of our random effect meta-analysis (a) indicate that computer-based scaffolding showed a consistently positive (ḡ = 0.46) effect on cognitive outcomes across various contexts of use, scaffolding characteristics, and levels of assessment and (b) shed light on many scaffolding debates, including the roles of customization (i.e., fading and adding) and context-specific support. Specifically, scaffolding’s influence on cognitive outcomes did not vary on the basis of context-specificity, presence or absence of scaffolding change, and logic by which scaffolding change is implemented. Scaffolding’s influence was greatest when measured at the principles level and among adult learners. Still scaffolding’s effect was substantial and significantly greater than zero across all age groups and assessment levels. These results suggest that scaffolding is a highly effective intervention across levels of different characteristics and can largely be designed in many different ways while still being highly effective.

    Many research studies conducted today in critical care have a genomics component. Patients' surrogates asked to authorize participation in genomics research for a loved one in the intensive care unit may not be prepared to make informed decisions about a patient's participation in the research. To examine the effectiveness of a new, computer-based education module on surrogates' understanding of the process of informed consent for genomics research. A pilot study was conducted with visitors in the waiting rooms of 2 intensive care units in a Midwestern tertiary care medical center. Visitors were randomly assigned to the experimental (education module plus a sample genomics consent form; n = 65) or the control (sample genomics consent form only; n = 69) group. Participants later completed a test on informed genomics consent. Understanding the process of informed consent was greater (P = .001) in the experimental group than in the control group. Specifically, compared with the control group, the experimental group had a greater understanding of 8 of 13 elements of informed consent: intended benefits of research (P = .02), definition of surrogate consenter (P= .001), withdrawal from the study (P = .001), explanation of risk (P = .002), purpose of the institutional review board (P = .001), definition of substituted judgment (P = .03), compensation for harm (P = .001), and alternative treatments (P = .004). Computer-based education modules may be an important addition to conventional approaches for obtaining informed consent in the intensive care unit. Preparing patients' family members who may consider serving as surrogate consenters is critical to facilitating genomics research in critical care. ©2015 American Association of Critical-Care Nurses.

    Many computer applications have been developed in radiology and other medical disciplines to help physicians make decisions. Artificial intelligence (AI)--an approach to computer-based manipulation of symbols to simulate human reasoning--forms the basis of many of these systems. This article's goals are to: acquaint the reader with the motivations and opportunities for computer-based medical decision support systems; identify AI techniques and applications in radiology decision making; assess the impact of these technologies; and consider new directions and opportunities for AI in radiology. Among the exciting new directions is the use of AI to integrate radiology reporting, online decision support, and just-in-time learning to provide useful information and continuing education that is embedded within a radiologist's daily workflow.

    Full Text Available One of the greatest problems in Plato that appears in different forms in his works is the relation of nomos and phusis. This thesis has been in fifth century B.C as the contradiction of phusis and nomos among big thinkers. In this essay, we tried to investigate the relation of phusis and nomos in Plato’s thoughts according to current theories of the contradiction of these in dialogues Gorgias, Republic and Protagoras. Plato tries to minimize consequences of belief to contradiction of phusis and nomos in social and political life by assertion large scale relation between phusis and nomos. Plato depicts the ultimate solution of this problem in Law. There he accounts nomos as raised from phusis that is sub sovereignty of divine. Indeed union of phusis and gods in Plato’s thought is sanction for the identity of phusis and nomos.

    The aim of the study was to evaluate the effect of an on-line, medication calculation education and testing programme. The outcome measures were medication calculation proficiency and self efficacy. This quasi-experimental study involved the administration of questionnaires before and after nurses completed annual medication calculation testing. The study was conducted in two hospitals in south-east Queensland, Australia, which provide a variety of clinical services including obstetrics, paediatrics, ambulatory, mental health, acute and critical care and community services. Participants were registered nurses (RNs) and enrolled nurses with a medication endorsement (EN(Med)) working as clinicians (n=107). Data pertaining to success rate, number of test attempts, self-efficacy, medication calculation error rates and nurses' satisfaction with the programme were collected. Medication calculation scores at first test attempt showed improvement following one year of access to the programme. Two of the self-efficacy subscales improved over time and nurses reported satisfaction with the online programme. Results of this study may facilitate the continuation and expansion of medication calculation and administration education to improve nursing knowledge, inform practise and directly improve patient safety.

    2016-01-01

    Background Computer-based learning (CBL) has been widely used in medical education, and reports regarding its usage and effectiveness have ranged broadly. Most work has been done on the effectiveness of CBL approaches versus traditional methods, and little has been done on the comparative effects of CBL versus CBL methodologies. These findings urged other authors to recommend such studies in hopes of improving knowledge about which CBL methods work best in which settings. Objective In this systematic review, we aimed to characterize recent studies of the development of software platforms and interventions in medical education, search for common points among studies, and assess whether recommendations for CBL research are being taken into consideration. Methods We conducted a systematic review of the literature published from 2003 through 2013. We included studies written in English, specifically in medical education, regarding either the development of instructional software or interventions using instructional software, during training or practice, that reported learner attitudes, satisfaction, knowledge, skills, or software usage. We conducted 2 latent class analyses to group articles according to platform features and intervention characteristics. In addition, we analyzed references and citations for abstracted articles. Results We analyzed 251 articles. The number of publications rose over time, and they encompassed most medical disciplines, learning settings, and training levels, totaling 25 different platforms specifically for medical education. We uncovered 4 latent classes for educational software, characteristically making use of multimedia (115/251, 45.8%), text (64/251, 25.5%), Web conferencing (54/251, 21.5%), and instructional design principles (18/251, 7.2%). We found 3 classes for intervention outcomes: knowledge and attitudes (175/212, 82.6%), knowledge, attitudes, and skills (11.8%), and online activity (12/212, 5.7%). About a quarter of the

    Full Text Available ABSTRACT Background: Nutrition education in school children is considered to be effective and efficient to touch big segment in population. Objective: To develop a computer-based nutritional education game-play for primary school children. Methods: Focus group interviews (focus groups were used to obtain insight into participants’ understanding and opinions regarding the healthy eating and physical-activity. Participants consisted of pupils (year 3 to 6 and their teachers in 3 cities in West Java Province: Depok, Bekasi, and Bandung. Two primary schools in each city selected purposively based on the recommendation of Dinas Pendidikan (Education Offices. This study included 2 phases. Phase I was focus groups involved 1 pupil group and 1 teacher group of 8 to 10 participants each. Focus group sessions were noted and summarized into meaningful themes for a developed computer-based nutritional education game-play. Phase II was created and test the game-play. Results: Key concepts of the healthy eating were commonly understood, but specific knowledge was limited, especially related to the recommended dietary allowance and food servings. Game-play is develop to be played and can be understood by students and teachers easily. From the trial game-play input obtained to repair the game. So at the end of the study can be obtained prototype game-play more interesting and can be more accepted by students and teachers. Although not all suggestions for improvements can be accommodated perfectly. Conclusion: The computer-based nutritional education game-play can be cheerfully used by year 1 to 6 of primary school children to enrich their knowledge about how much food should they eat a day based on their body needs.

    2017-09-01

    In a two-group, multi-centre, randomised controlled 9 months trial, we (1) evaluated the impact of a computer-based educational programme compared to standard care and (2) examined whether different patterns of programme usage could be explained by demographic, medical and psychosocial factors. We involved 226 Swedish-speaking women diagnosed with early-stage breast cancer and scheduled for surgery. Primary outcomes were health self-efficacy and health care participation measured by the Comprehensive Health Enhancement Supportive System instrument. Secondary outcomes were anxiety and depression levels measured by the Hospital Anxiety and Depression scale. The Functional Assessment of Cancer Therapy-Breast and Sense of Coherence scales measured psychosocial factors for the study's secondary aim. Multi-level modelling revealed no statistically significant impact of the computer-based educational programme over time on the outcomes. Subsequent exploratory regression analysis revealed that older women with axillary dissection and increased physical well-being were more likely to use the programme. Furthermore, receiving post-operative chemotherapy and increased meaningfulness decreased the likelihood of use. Providing reliable and evidence-based medical and rehabilitation information via a computer-based programme might not be enough to influence multi-dimensional outcomes in women diagnosed with breast cancer. The use of these programmes should be further explored to promote adherence to e-Health supportive interventions. © 2016 John Wiley & Sons Ltd.

This method, respectively, will be examined in three dialogues of Meno, Phaedon and Republic in which it is explicitly indicated. It will be shown the process of change of Plato’s attitude towards the position and usage of the method of hypothesis in his realm of philosophy. In Meno, considering the geometry, Plato attempts to introduce a method that can be used in the realm of philosophy. But, ultimately in Republic, Plato’s special attention to the method and its importance in the philosophical investigations, leads him to revise it. Here, finally Plato introduces the particular method of philosophy, i.e., the dialectic

    Full Text Available The article presents a philosophical analysis of the phenomenon of Plato’s love. It is noted that a large number of works are devoted to the philosophy of Plato’s love, but not all aspects of his philosophy are studied, for example the problems of erotosophy of Plato. Phenomenon of love interested philosophers since ancient times. The first attempts to explain the phenomenon of love appeared in ancient times. These attempts were made by ancient philosophers Socrates, Plato and Aristotle. Platonism is a multifaceted teaching; identification of all possibilities of Plato’s erotic philosophy which can supplement other fields of philosophy is important and topical.

    To determine the impact of a low-resource-demand, easily disseminated computer-based teamwork process training intervention on teamwork behaviors and patient care performance in code teams. A randomized comparison trial of computer-based teamwork training versus placebo training was conducted from August 2010 through March 2011. This study was conducted at the simulation suite within the Kado Family Clinical Skills Center, Wayne State University School of Medicine. Participants (n = 231) were fourth-year medical students and first-, second-, and third-year emergency medicine residents at Wayne State University. Each participant was assigned to a team of four to six members (nteams = 45). Teams were randomly assigned to receive either a 25-minute computer-based training module targeting appropriate resuscitation teamwork behaviors or a placebo training module. Teamwork behaviors and patient care behaviors were video recorded during high-fidelity simulated patient resuscitations and coded by trained raters blinded to condition assignment and study hypotheses. Teamwork behavior items (e.g., "chest radiograph findings communicated to team" and "team member assists with intubation preparation") were standardized before combining to create overall teamwork scores. Similarly, patient care items ("chest radiograph correctly interpreted"; "time to start of compressions") were standardized before combining to create overall patient care scores. Subject matter expert reviews and pilot testing of scenario content, teamwork items, and patient care items provided evidence of content validity. When controlling for team members' medically relevant experience, teams in the training condition demonstrated better teamwork (F [1, 42] = 4.81, p teamwork and patient care during simulated patient resuscitations. This low-resource team training intervention may help to address the dissemination and sustainability issues associated with larger, more costly team training programs.

  8. What scientists can learn from Plato's Symposium

    2015-04-01

    Conferences and scientific meetings are as old as science itself. The ancient Greeks where (in)famous for organizing so-called symposiums. During a symposium (from Greek, drinking together), attendees followed a program that contained both social and scientific aspects, focused around a certain topic. Whilst drinking and eating, all participants were expected to share their vision on the topic of interest by giving an oral presentation. The goal of these meetings was to arrive at a new common understanding and to come closer to the truth. Plato et al. knew very well how to organize an effective scientific conference, which should make use overthink the way we are organizing present-day conferences. Scientific meetings aim to connect researchers, share research and unravel the truth. The question is now: how do we get this done effectively? Plato knew that discussing science with strangers is difficult and he believed that talking about heavy matter could be done best when combined with social events. What if we try to go back to the times of Plato and model our conferences after the ancient symposiums? We might drop laying on couches and covering ourselves in ivy and flowers. However, a mix of social and scientific events will contribute to achieving the ultimate goal of why scientists go to conferences: to connect, to share and to unravel the truth.

    Innovation in technology drives innovation in assessment. Since the introduction of computer-based assessment (CBA), a few decades ago, many formerly paper-and-pencil tests have transformed in a computer-based equivalent. CBAs are becoming more complex, including multimedia and simulative elements and even immersive virtual environments. In Vocational Education and Training (VET), test developers may seize the opportunity provided by technology to create a multimedia-based equivalent of perfo...

  12. The fundamental characters of soma in Plato's later dialogues: an introduction to the reanalysis of Plato's physical education theory%柏拉图后期对话篇中"身体(soma)"的原理性特征——柏拉图体育论再考的前提

    This paper aims to clarify Plato's view of soma through consideration of the fundamental characters of soma in Plato's later dialogues. Soma, which had a very large extension in classical Greek, denotes not only the hu-man body but also the elemental bodies (fire, water, air, earth), the corpse, the cosmic body, the celestial body, the animal body, etc, and there also lies such a large extension in the background of the Plato's view of the human body.According to Laws, Plato's last work, soma has three common characters: spaciality, movability and sensibil-ity, and takes on a different aspect fi'om the body in the present age. Firstly, the spaciality of soma is the likeness of Form, which is copied into chora (the place of plenum), and it is the solid, which is geometrically formed by fol-lowing Form. Secondly, the movability of soma is originally motion by others or disorderly and dotted linear mo-tion, which is necessarily caused by the accidental collision between the particles, but in connection with Soul and Reason it becomes a pseudo-autonomous and orderly circular motion. Thirdly, the sensibility of soma is pathema (accidental affection), which is based on the multiplicity in the geometrical structures of the particles. Pathema in-jutes Soul and soma when it is left to Chance and Ignorance, but in the control of Reason it contributes to the reali-zation of the good and the restoration of the order.Since soma, which has close connections to Soul, Reason and Form, is represented as such a subordinate and necessarily conditional existence in Plato's later dialogues, the hu-man body, which is also called soma, should be considered on the basis of the above mentioned fundamental char-acters.%通过考察柏拉图后期对话篇中"身体(soma)"的原理性特征,阐明柏拉图身体(soma)观."身体(soma)"是具有极其宽广外延的词汇,不仅指人的身体,还代指动物的躯体、宇宙或天体的结构、丧失生命的尸体,甚至具有构成基

    Health education has been recognised as a specific intervention tool for control of Taenia solium taeniosis/cysticercosis but evaluation of the efficacy of the tool remains. The aim of our study was to assess the effect of a computer-based T. solium health education tool 'The Vicious Worm' on knowledge uptake among professionals and investigate attitudes towards the program. The study was carried out between March and May 2014 in Mbeya Region, Tanzania, where T. solium is endemic. The study was a pre and post assessment of a health education tool based on questionnaire surveys and focus group discussions to investigate knowledge and attitudes. A total of 79 study subjects participated in the study including study subjects from both health- and agriculture sector. The health education consisted of 1½h individual practice with the computer program. The baseline questionnaire showed an overall knowledge on aspects of acquisition and transmission of T. solium infections (78%), porcine cysticercosis treatment (77%), human tapeworm in general (72%), neurocysticercosis in general (49%), and porcine cysticercosis diagnosis (48%). However, there was a lack of knowledge on acquisition of neurocysticercosis (15%), prevention of T. solium taeniosis/cysticercosis (28%), and relation between porcine cysticercosis, human cysticercosis, and taeniosis (32%). Overall, the study subject's knowledge was significantly improved both immediately after (p=0.001) and two weeks after (psolium taeniosis/cysticercosis control.

    In neurosurgery education, there is a paradigm shift from time-based training to criterion-based model for which competency and assessment becomes very critical. Even virtual reality simulators provide alternatives to improve education and assessment in neurosurgery programs and allow for several objective assessment measures, there are not many tools for assessing the overall performance of trainees. This study aims to develop and validate a tool for assessing the overall performance of participants in a simulation-based endoneurosurgery training environment. A training program was developed in two levels: endoscopy practice and beginning surgical practice based on four scenarios. Then, three experiments were conducted with three corresponding groups of participants (Experiment 1, 45 (32 beginners, 13 experienced), Experiment 2, 53 (40 beginners, 13 experienced), and Experiment 3, 26 (14 novices, 12 intermediate) participants). The results analyzed to understand the common factors among the performance measurements of these experiments. Then, a factor capable of assessing the overall skill levels of surgical residents was extracted. Afterwards, the proposed measure was tested to estimate the experience levels of the participants. Finally, the level of realism of these educational scenarios was assessed. The factor formed by time, distance, and accuracy on simulated tasks provided an overall performance indicator. The prediction correctness was very high for the beginners than the one for experienced surgeons in Experiments 1 and 2. When non-dominant hand is used in a surgical procedure-based scenario, skill levels of surgeons can be better predicted. The results indicate that the scenarios in Experiments 1 and 2 can be used as an assessment tool for the beginners, and scenario-2 in Experiment 3 can be used as an assessment tool for intermediate and novice levels. It can be concluded that forming the balance between perceived action capacities and skills is

    2008-01-01

    Plato's Ghost is the first book to examine the development of mathematics from 1880 to 1920 as a modernist transformation similar to those in art, literature, and music. Jeremy Gray traces the growth of mathematical modernism from its roots in problem solving and theory to its interactions with physics, philosophy, theology, psychology, and ideas about real and artificial languages. He shows how mathematics was popularized, and explains how mathematical modernism not only gave expression to the work of mathematicians and the professional image they sought to create for themselves, but how modernism also introduced deeper and ultimately unanswerable questions

    PLATO 2.0 is a mission candidate for ESA's M3 launch opportunity (2022/24). It addresses fundamental questions such as: How do planetary systems form and evolve? Are there other systems with planets like ours, able to develop life? The PLATO 2.0 instrument consists of 34 small aperture telescopes providing a wide field-of-view and a large photometric magnitude range. It targets bright stars in wide fields to detect and characterize planets down to Earth-size by photometric transits, whose masses can then be determined by ground-based radial-velocity follow-up measurements. Asteroseismology will be performed for stars <=11mag to obtain highly accurate stellar parameters, including masses and ages. The combination of bright targets and asteroseismology results in high accuracy for the bulk planet parameters: 2%, 4-10% and 10% for planet radii, masses and ages, respectively. The foreseen baseline observing strategy includes two long pointings (2-3 years) to detect and bulk characterize planets reaching into t...

  13. Plato on Metaphysical Explanation: Does 'Participating' Mean Nothing?

    Directory of Open Access Journals (Sweden)

    Christine J. Thomas

    2014-12-01

    Full Text Available According to Aristotle, Plato's efforts at metaphysical explanation not only fail, they are nonsensical. In particular, Plato's appeals to Forms as metaphysically explanatory of the sensibles that participate in them is "empty talk" since "'participating' means nothing" (Met. 992a28-9. I defend Plato against Aristotle's charge by identifying a particular, substantive model of metaphysical predication as the favored model of Plato's late ontology. The model posits two basic metaphysical predication relations: self-predication and participation. In order to understand the participation relation, it is important first to understand how Plato's Forms are self-predicative paradigms. According to the favored model, Forms are self-predicative paradigms insofar as they are ideal, abstract encoders of structural essences. Sensibles participate in Forms by exemplifying the structures encoded in the Forms. Given plausible conditions on metaphysical explanation, Plato's appeals to abstract Forms as metaphysically explanatory of sensibles is a reasonable competitor for Aristotle's appeals to natural, substantial forms. At the very least, Plato's appeals to a participation relation are not empty.

  15. A scientific approach to Plato's Atlantis

    Directory of Open Access Journals (Sweden)

    Massimo Rapisarda

    2015-09-01

    Full Text Available The myth of Atlantis is hard to die. This attempt to use scientific evidence to give it the final smash ends up with the doubt that it might not be totally unsubstantiated. The time of the supposed existence of Atlantis (around twelve thousand years ago was, in fact, characterized by technological revolutions, acknowledged by archaeology, and abrupt climate changes, documented by geology. In principle, it cannot therefore be ruled out that some of those dramatic events left a memory, later used by Plato as a basis for its tale. The climate changes involved the majority of the northern hemisphere, thus all the ancient civilizations (Egyptian, Mesopotamian, Indian and Chinese could have preserved reminiscence, but it is clear that the events occurring closer to Greece would have been more accessible to Plato. Among the Mediterranean sites that experienced the cataclysms of the beginning of the Holocene, a good candidate to host a primordial civilization might have been the archipelago then existing in the Strait of Sicily, a natural maritime link between Tunisia and Italy, prized by the presence of an obsidian source at Pantelleria. Eleven thousand five hundred years ago, a sudden sea level rise erased the archipelago, submerging the possible settlements, but Pantelleria obsidian ores are still there and could provide a significant clue. In fact, the potential discovery of artefacts, originating from a source now submerged by the sea level rise, would imply that the collection of the mineral took place when it was still emerged, namely at the time of Atlantis. Even if such discovery would not be sufficient to prove the existence of the mythical island, it would be enough to shake up the timeline of the human occupation in the region.

  19. What Plato and Murdoch Think About Love

    Directory of Open Access Journals (Sweden)

    Shadi Shakouri

    2012-07-01

    Full Text Available There are many interpretations of love and lots of scholars write and talk on love; however, what exactly is the meaning of love? Iris Murdoch’s works are an accumulation of emotional relationships and feelings of love. Her great subject is love, both sexual and non-sexual, and her characters are the portrayal of a small group of people caught up in convoluted ties of love and hate, with Eros ruling over them (Cohen 22. Murdoch was one of the most respected British writers and philosophers of the second half of the twentieth century and, of course, the postwar period. In Murdoch’s novels, love is one of the central themes—marriage, as the institution of love, more often binds than frees. Her characters are mainly ego-centric people who struggle to love and are often overwhelmed by the factor of self-obsession, jealousy, ambition, fascination with suffering and charismatic power. They are absolutely ordinary people with a consuming demand for love, and mental and physical exile. Murdoch was inspired by Plato’s ideas in many ways. Like art, here again Plato’s idea of love is more skeptical than Murdoch’s, whereas Murdoch kept it only as a way to the Good, creation, and happiness. Murdoch and Plato saw love more as a Freudian concept, the Eros, the word that comes from the name of the first Greek god of love. Both the philosophers, Plato and Murdoch, believed that this erotic longing and desires revived by Eros can led to a new direction, a way toward virtue and truth. Her protagonist or marginalized characters are usually tackling it with either vulgarity or the heavenly, which results in creation, art or salvation. Murdoch, as a major moral philosopher, usually grasps the chances to encapsulate her moral visions in her works, and created novels that should be counted as meditations on human love and goodness. Keywords: Eros, erotic love and real artwork, moral philosopher, The Black Prince

    This paper considers the conflicting "loves" of Cornelius Castoriadis--his love for the ancients, and especially Plato, and for the common person of the demos. A detailed study of Castoriadis' analysis of Plato's Statesman exposes that Castoriadis attempts to resolve the paradox by rereading Plato as a radical democrat. I argue that this unorthodox reading is at best "quirky, " (a charge Castoriadis levels at Plato) at worst a groundless sophism. However, I conjecture that Castoriadis' readin...

  1. Eugenics concept: from Plato to present.

    Güvercin, C H; Arda, B

    2008-01-01

    All prospective studies and purposes to improve cure and create a race that would be exempt of various diseases and disabilities are generally defined as eugenic procedures. They aim to create the "perfect" and "higher" human being by eliminating the "unhealthy" prospective persons. All of the supporting actions taken in order to enable the desired properties are called positive eugenic actions; the elimination of undesired properties are defined as negative eugenics. In addition, if such applications and approaches target the public as a whole, they are defined as macro-eugenics. On the other hand, if they only aim at individuals and/or families, they are called micro-eugenics. As generally acknowledged, Galton re-introduced eugenic proposals, but their roots stretch as far back as Plato. Eugenic thoughts and developments were widely accepted in many different countries beginning with the end of the 19th to the first half of the 20th centuries. Initially, the view of negative eugenics that included compulsory sterilizations of handicapped, diseased and "lower" classes, resulted in tens of thousands being exterminated especially in the period of Nazi Germany. In the 1930s, the type of micro positive eugenics movement found a place within the pro-natalist policies of a number of countries. However, it was unsuccessful since the policy was not able to become effective enough and totally disappeared in the 1960s. It was no longer a fashionable movement and left a deep impression on public opinion after the long years of war. However, developments in genetics and its related fields have now enabled eugenic thoughts to reappear under the spotlight and this is creating new moral dilemmas from an ethical perspective.

  3. Plato's Cosmic Theology: A Rationale for a Polytheistic Astrology?

    Science.gov (United States)

    Henriques, André

    2015-05-01

    Plato's cosmology influenced classical astronomy and religion, but was in turn influenced by the polytheistic context of its time. Throughout his texts, including the cosmological treatise Timaeus, and the discussions on the soul in the Phaedrus, Plato (c.428-c.348 BC) established what can be generalised as Platonic cosmological thought. An understanding of the philosophical and mythical levels of Platonic thought can provide a rationale for polytheistic and astrological worldviews, pointing to some cosmological continuity, alongside major shifts, from ancient Greek religion to the astrological thought of ancient astronomers such as Claudius Ptolemy.

    PLATO is a self-contained robotic observatory built into two 10-foot shipping containers. It has been successfully deployed at Dome A on the Antarctic plateau since January 2008, and has accumulated over 730 days of uptime at the time of writing. PLATO provides 0.5{1kW of continuous electrical power for a year from diesel engines running on Jet-A1, supplemented during the summertime with solar panels. One of the 10-foot shipping containers houses the power system and fuel, the other provides a warm environment for instruments. Two Iridium satellite modems allow 45 MB/day of data to be transferred across the internet. Future enhancements to PLATO, currently in development, include a more modular design, using lithium iron-phosphate batteries, higher power output, and a light-weight low-power version for eld deployment from a Twin Otter aircraft. Technologies used in PLATO include a CAN (Controller Area Network) bus, high-reliability PC/104 com- puters, ultracapacitors for starting the engines, and fault-tolerant redundant design.

  16. Arete and physics: The lesson of Plato's "Timaeus"

    Science.gov (United States)

    Wolfe, John R.

    Plato's Timaeus is traditionally read as a work dedicated to the sole purpose of describing the origin and nature of the cosmos, as a straightforward attempt by Plato to produce a peri phuseos treatise. In accord with this reading, the body of Timaeus' monologue is then seen as nothing more than an attempt by Plato to convey his own cosmological doctrines. I propose an alternative to the view that the Timaeus is nothing more than a textbook of Platonic physics. The Timaeus is rather squarely focused on the human being, in her moral and political dimensions, and on her relation to the natural world as a whole. Ultimately, this account of the human being is intended to provide part of the answer to the question of how society can produce good citizens and leaders, and thus serves to provide a theoretical basis for the practices of paideia. When viewed in this light many of the curious features of the Timaeus appear less strange. The various parts of the dialogue: the dramatic introduction, Critias' tale of the Ancient Athenians, and Timaeus' monologue can be seen as each contributing to an investigation of a single topic. It further allows us to understand why Plato chooses to employ Timaeus the Locrian as the principle speaker of the dialogue rather than Socrates. Finally, when read in this way, the Timaeus no longer appears as an outlier in the Platonic corpus, as a work devoted to a radically different subject matter than the rest of his writings. It can be seen as dedicated to the same issues which preoccupied Plato throughout his entire life, as about the determination of the best life and providing the tools with which to realize it.

  20. THE JOURNEY OF TRUTH: FROM PLATO TO ZOLA

    Directory of Open Access Journals (Sweden)

    Ribut Basuki

    1999-01-01

    Full Text Available Western theater theory and criticism is generally considered to be set forth by the Greeks. Plato was "the first theater critic" with his negative comments about theater owing to his idealistic views about "the truth." Then came Aristotle who used a different viewpoint from that of Plato, saying that there is "truth" in theater. However, hostile criticism on theater came back in the Middle Ages, championed by Tertulian before Aristotelian theory was revived by the neo-classicists such as Scaliger and Castelvetro. Theater theory and criticism discourse was then made more alive by the romanticists who disagreed with the neo-classicists' rigid rules on theater. As the influence of science became dominant in the theater world, naturalism and realism emerged and became the mainstream of theater theory and criticism until well into the twentieth century.

    PLATO - PLAnetary Transits and Oscillations of stars - is the third medium-class mission (M3) to be selected in the European Space Agency (ESA) Science and Robotic Exploration Cosmic Vision programme. It is due for launch in 2025 with the main objective to find and study terrestrial planets in the habitable zone around solar-like stars. The payload consists of >20 cameras; with each camera comprising 4 Charge-Coupled Devices (CCDs), a large number of flight model devices procured by ESA shall ultimately be integrated on the spacecraft. The CCD270 - specially designed and manufactured by e2v for the PLATO mission - is a large format (8 cm x 8 cm) back-illuminated device operating at 4 MHz pixel rate and coming in two variants: full frame and frame transfer. In order to de-risk the PLATO CCD procurement and aid the mission definition process, ESA's Payload Technology Validation section is currently validating the PLATO CCD270. This validation consists in demonstrating that the device achieves its specified electrooptical performance in the relevant environment: operated at 4 MHz, at cold and before and after proton irradiation. As part of this validation, CCD270 devices have been characterized in the dark as well as optically with respect to performance parameters directly relevant for the photometric application of the CCDs. Dark tests comprise the measurement of gain sensitivity to bias voltages, charge injection tests, and measurement of hot and variable pixels after irradiation. In addition, the results of measurements of Quantum Efficiency for a range of angles of incidence, intra- pixel response (non-)uniformity, and response to spot illumination, before and after proton irradiation. In particular, the effect of radiation induced degradation of the charge transfer efficiency on the measured charge in a star-like spot has been studied as a function of signal level and of position on the pixel grid, Also, the effect of various levels of background light on the

    2008-08-01

    Full Text Available The tibial plateau leveling osteotomy (TPLO is a relatively new and innovative surgical treatment for the cranial cruciate ligament rupture in the canine species. The real intent of the procedure is to provide functional stability to the stifle joint by eliminating or neutralizing the cranial tibial thrust during weight bearing instead to restore the cranial cruciate ligament function. The proposal of this study is to report a review of the TPLO procedure, emphasizing procedure, surgical technique, post operative care and complications. The TPLO procedure consists in a radial osteotomy in the tibial plato and rotation of the caudal plateau in order to obtain a desired angle. After the leveling of the tibial plateau, a bone plate and screws are used to stabilize the osteotomy until bone is healed up. The complications that have been associated with the procedure include tibial tuberosity fracture and patellar tendon tendinosis. This procedure has become increasingly more popular for surgical treatment of cranial cruciate ligament injuries in large breed dog. The long term clinical results have not been completely elucidated yet. It has been showed that this technique doesn’t halt the degenerative joint disease.A osteotomia do platô da tíbia (TPLO é um tratamento relativamente novo e inovador para a ruptura do ligamento cruzado cranial (RLCC na espécie canina.

A proposta do presente estudo é revisar a técnica de TPLO, enfatizando o procedimento, técnica cirúrgica, cuidados pós-operatórios e complicações. A técnica da TPLO consiste na realização de uma osteotomia circular do platô da tíbia com rotação de sua porção caudal até a obtenção do ângulo desejado.

    Full Text Available This paper considers the conflicting "loves" of Cornelius Castoriadis--his love for the ancients, and especially Plato, and for the common person of the demos. A detailed study of Castoriadis' analysis of Plato's Statesman exposes that Castoriadis attempts to resolve the paradox by rereading Plato as a radical democrat. I argue that this unorthodox reading is at best "quirky, " (a charge Castoriadis levels at Plato at worst a groundless sophism. However, I conjecture that Castoriadis' reading may not constitute a serious attempt to describe a Platonic politics, so much as a prescriptive reading of what otherwise might have been, given certain strands of political generosity evident elsewhere in Plato's corpus.

    The project PLAnetary Transits and Oscillations of stars (PLATO) is one of the selected medium class (M class) missions in the framework of the ESA Cosmic Vision 2015-2025 program. The mean scientific goal of PLATO is the discovery and study of extrasolar planetary systems by means of planetary transits detection. The opto mechanical subsystem of the payload is made of 32 normal telescope optical units (N-TOUs) and 2 fast telescope optical units (FTOUs). The optical configuration of each TOU is an all refractive design based on six properly optimized lenses. In the current baseline, in front of each TOU a Suprasil window is foreseen. The main purposes of the entrance window are to shield the following lenses from possible damaging high energy radiation and to mitigate the thermal gradient that the first optical element will experience during the launch from ground to space environment. In contrast, the presence of the window increases the overall mass by a non-negligible quantity. We describe here the radiation and thermal analysis and their impact on the quality and risks assessment, summarizing the trade-off process with pro and cons on having or dropping the entrance window in the optical train.

    The project PLAnetary Transits and Oscillations of stars (PLATO) is one of the selected medium class (M class) missions in the framework of the ESA Cosmic Vision 2015-2025 program. The main scientific goal of PLATO is the discovery and study of extrasolar planetary systems by means of planetary transits detection. According to the current baseline, the scientific payload consists of 34 all refractive telescopes having small aperture (120mm) and wide field of view (diameter greater than 37 degrees) observing over 0.5-1 micron wavelength band. The telescopes are mounted on a common optical bench and are divided in four families of eight telescopes with an overlapping line-of-sight in order to maximize the science return. Remaining two telescopes will be dedicated to support on-board star-tracking system and will be specialized on two different photometric bands for science purposes. The performance requirement, adopted as merit function during the analysis, is specified as 90% enclosed energy contained in a square having size 2 pixels over the whole field of view with a depth of focus of +/-20 micron. Given the complexity of the system, we have followed a Montecarlo analysis approach for manufacturing and alignment tolerances. We will describe here the tolerance method and the preliminary results, speculating on the assumed risks and expected performances.

    2003-05-01

    A challenging task in educational research today is to understand the implications of recent developments in computer-based learning environments. On the other hand, questions regarding learning and mathematical cognition have long been a central focus of research in mathematics education. Adding technology compounds an already complex problematic. Fortunately, computer-based technology also provides researchers with new ways of studying cognition and instruction. This paper introduces a new method for dynamically tracking learners' experiences in computer-based learning environments. Dynamic tracking is illustrated in both a classroom and a clinical setting by drawing on two studies with elementary preservice teachers working in computer-based mathematics learning environments.

    Full Text Available Argumentation is nowadays seen both as skill that people use in various aspects of their lives, as well as an educational technique that can support the transfer or creation of knowledge thus aiding in the development of other skills (e.g. Communication, critical thinking or attitudes. However, teaching argumentation and teaching with argumentation is still a rare practice, mostly due to the lack of available resources such as time or expert human tutors that are specialized in argumentation. Intelligent Computer Systems (i.e. Systems that implement an inner representation of particular knowledge and try to emulate the behavior of humans could allow more people to understand the purpose, techniques and benefits of argumentation. The proposed paper investigates the state of the art concepts of computer-based argumentation used in education and tries to develop a conceptual map, showing benefits, limitation and relations between various concepts focusing on the duality “learning to argue – arguing to learn”.

    Directory of Open Access Journals (Sweden)

    2016-12-01

    Full Text Available The issues influencing student engagement with high-stakes computer-based exams were investigated, drawing on feedback from two cohorts of international MA Education students encountering this assessment method for the first time. Qualitative data from surveys and focus groups on the students’ examination experience were analysed, leading to the identification of engagement issues in the delivery of high-stakes computer-based assessments.The exam combined short-answer open-response questions with multiple-choice-style items to assess knowledge and understanding of research methods. The findings suggest that engagement with computer-based testing depends, to a lesser extent, on students’ general levels of digital literacy and, to a greater extent, on their information technology (IT proficiency for assessment and their ability to adapt their test-taking strategies, including organisational and cognitive strategies, to the online assessment environment. The socialisation and preparation of students for computer-based testing therefore emerge as key responsibilities for instructors to address, with students requesting increased opportunities for practice and training to develop the IT skills and test-taking strategies necessary to succeed in computer-based examinations. These findings and their implications in terms of instructional responsibilities form the basis of a proposal for a framework for Learner Engagement with e-Assessment Practices.

  18. Love as an Object of Initiation in Plato's Philosophy

    Directory of Open Access Journals (Sweden)

    Euaggelia Maraggianou

    2007-07-01

    Full Text Available Initiation ( muvhsh was the first stage of the ancient mysteries celebrating Demeter, the earth-goddess, and her daughter Kore, soon identified with Persephone or Persephasa, a pre-Greek deity of the underworld. Next came the stage of contemplation ( ejpopteiva , at which worshippers were shown a vision of the goddess of Hades. This led them to identify themselves with her, thus reaching the highest form of happiness. The Eleusinian Mysteries were inseparably linked to the Orphic doctrine, which in its turn influenced the thought of Plato. Plato sees love as an object of initiation and as one of the greatest mysteries of human existence. Plato’s dialogues, Phaedrus and Symposium, contain expressions borrowed directly from the vocabulary of the Mysteries. Although neither Socrates in Phaedrus nor Diotima in Symposium make any explicit reference to the mystic ceremonies, it is certain that both allude to them in expounding the mysteries of spiritual life. The latter has to start at the stage of physical love in order to end up in the contemplation of Ideas. The mystery into which Socrates is initiated by Diotima is the following: there is a mystic stairway leading from the earth to the sky, from man to God. It is made visible by Love, and its steps are represented by different kinds of beauty. The ascent is a gradual one, with a long stop at each of the stages. In this way Love, disciplined by philosophy and spiritualised by increasing de-personalisation, ends up in the Intellectual, conceiving the latter with an intuitive insight. By this spiritual process, one is purified, led to the road of salvation and enabled to participate in the Divine.

    Deciphering the assembly history of the Milky Way is a formidable task, which becomes possible only if one can produce high-resolution chrono-chemo-kinematical maps of the Galaxy. Data from large-scale astrometric and spectroscopic surveys will soon provide us with a well-defined view of the current chemo-kinematical structure of the Milky Way, but will only enable a blurred view on the temporal sequence that led to the present-day Galaxy. As demonstrated by the (ongoing) exploitation of data from the pioneering photometric missions CoRoT, Kepler, and K2, asteroseismology provides the way forward: solar-like oscillating giants are excellent evolutionary clocks thanks to the availability of seismic constraints on their mass and to the tight age-initial-mass relation they adhere to. In this paper we identify five key outstanding questions relating to the formation and evolution of the Milky Way that will need precise and accurate ages for large samples of stars to be addressed, and we identify the requirements in terms of number of targets and the precision on the stellar properties that are needed to tackle such questions. By quantifying the asteroseismic yields expected from PLATO for red-giant stars, we demonstrate that these requirements are within the capabilities of the current instrument design, provided that observations are sufficiently long to identify the evolutionary state and allow robust and precise determination of acoustic-mode frequencies. This will allow us to harvest data of sufficient quality to reach a 10% precision in age. This is a fundamental pre-requisite to then reach the more ambitious goal of a similar level of accuracy, which will only be possible if we have to hand a careful appraisal of systematic uncertainties on age deriving from our limited understanding of stellar physics, a goal which conveniently falls within the main aims of PLATO's core science.

    Full Text Available [english] Purpose: Anatomy is an important subject in the education of radiographers and radiotherapy technicians. The enormous amount of information may render efficient learning more difficult and lead to sub-optimal results. The purpose of this study was to test whether the introduction of a computer-based tutorial enhances learning success in anatomy. Methods: A commercially available tutorial in anatomy especially adapted to the requirements of the education of radiographers and which facilitated and structured the frequent repetition of the material was introduced into the conventional curriculum. The tutorial was used during normal lessons, and work with it was obligatory. The students could learn anatomical structures and landmarks repeatedly as well as test themselves. The scores obtained in the final examinations two years prior to introduction of this tutorial were compared with those obtained two years after introduction. Results: Students’ knowledge in anatomy could be markedly improved. Conclusion: An efficient and time-saving method of learning became possible. It was important to integrate the tutorial into the normal curriculum. The test results show the feasibility of this educational concept. [german] Zielsetzung: In der MTA-Ausbildung nimmt Anatomie einen wichtigen Platz ein. Die große Stofffülle erschwert jedoch ein effizientes zeitsparendes Lernen und führt auch bei motivierten Schülern oft zu mangelndem Lernerfolg. Es sollte geprüft werden, ob dieser durch Einführung computerbasierten Lernens verbessert werden kann. Methodik: Ein auf die Erfordernisse der MTRA-Ausbildung von den Autoren angepasstes kommerzielles Anatomie-Lernprogramm, das den Schülern das notwendige häufige Wiederholen des Materials erleichtert und strukturiert, wurde im Rahmen des Pflichtunterrichtes den Schülern zur Verfügung gestellt. Diese konnten damit anatomische Sachverhalte sich einprägen, beliebig oft wiederholen und ihr Wissen testen

  3. Prospects for detecting decreasing exoplanet frequency with main sequence age using PLATO

    2015-01-01

    The space mission PLATO will usher in a new era of exoplanetary science by expanding our current inventory of transiting systems and constraining host star ages, which are currently highly uncertain. This capability might allow PLATO to detect changes in planetary system architecture with time, particularly because planetary scattering due to Lagrange instability may be triggered long after the system was formed. Here, we utilize previously published instability timescale prescriptions to determine PLATO's capability to detect a trend of decreasing planet frequency with age for systems with equal-mass planets. For two-planet systems, our results demonstrate that PLATO may detect a trend for planet masses which are at least as massive as super-Earths. For systems with three or more planets, we link their initial compactness to potentially detectable frequency trends in order to aid future investigations when these populations will be better characterized.

    The atmospheric conditions above Dome A, a currently unmanned location at the highest point on the Antarctic plateau, are uniquely suited to astronomy. For certain types of astronomy Dome A is likely to be the best location on the planet, and this has motivated the development of the Plateau Observatory (PLATO). PLATO was deployed to Dome A in early 2008. It houses a suite of purpose-built site-testing instruments designed to quantify the benefits of Dome A site for astronomy, and science instruments designed to take advantage of the observing conditions. The PLATO power generation and control system is designed to provide continuous power and heat, and a high-reliability command and communications platform for these instruments. PLATO has run and collected data throughout the winter 2008 season completely unattended. Here we present a detailed description of the power generation, power control, thermal management, instrument interface, and communications systems for PLATO, and an overview of the system performance for 2008.

  14. Gaia and WEAVE/WxES: Supporting the PLATO Exoplanet Hunter

    Walton, N. A.

    2016-10-01

    This paper briefly describes the powerful linkages between the Gaia and PLATO missions and the potential for WEAVE in the study of exoplanet populations, for instance through the proposed WxES survey. Gaia successfully launched in December 2013, and over the course of its nominal five year mission will discover, via their astrometric signatures, upwards of 20 000 massive Jupiter sized long period planets at distances out to several hundred parsecs around all star types. In addition Gaia will discover up to a thousand short period hot Jupiters around M stars. PLATO, to launch in 2024, will through precision photometry, observe in detail some million host stars, and will detect, via the transit technique, planets down to Earth masses. PLATO will observe two fields of over 2 000 square degrees for 2-3 years each. At least one of these will be in the northern hemisphere. WEAVE has the potential to provide detailed chemical characterization of the host stars of the Gaia and PLATO exoplanet systems. This will enable insights into, for instance, metallicity of the host star correlations against both massive exoplanets (perhaps confirming current relationships), and lower mass exoplanets. We note how the rapid exploitation of such a potential WEAVE survey could be achieved, utilizing the WEAVE processing systems being developed at the IoA, Cambridge, coupled with efficient interfaces to both Gaia and PLATO data products, that are also being generated at the IoA.

  17. Redesigning Computer-based Learning Environments: Evaluation as Communication

    CERN Document Server

    Brust, Matthias R; Ricarte, Ivan M L

    2007-01-01

    In the field of evaluation research, computer scientists live constantly upon dilemmas and conflicting theories. As evaluation is differently perceived and modeled among educational areas, it is not difficult to become trapped in dilemmas, which reflects an epistemological weakness. Additionally, designing and developing a computer-based learning scenario is not an easy task. Advancing further, with end-users probing the system in realistic settings, is even harder. Computer science research in evaluation faces an immense challenge, having to cope with contributions from several conflicting and controversial research fields. We believe that deep changes must be made in our field if we are to advance beyond the CBT (computer-based training) learning model and to build an adequate epistemology for this challenge. The first task is to relocate our field by building upon recent results from philosophy, psychology, social sciences, and engineering. In this article we locate evaluation in respect to communication s...

  18. The role of the poet in Plato's ideal cities of Callipolis and Magnesia

    2008-01-01

    Full Text Available Plato's attitude toward the poets and poetry has always been a flashpoint of debate, controversy and notoriety, but most scholars have failed to see their central role in the ideal cities of the Republic and the Laws, that is, Callipolis and Magnesia. In this paper, I argue that in neither dialogue does Plato "exile" the poets, but, instead, believes they must, like all citizens, exercise the expertise proper to their profession, allowing them the right to become full-fledged participants in the productive class. Moreover, attention to certain details reveals that Plato harnesses both positive and negative factors in poetry to bring his ideal cities closer to a practical realization. The status of the poet and his craft in this context has rarely to my knowledge been addressed.

    A new site-testing facility, PLATO (Plateau Observatory), is under development at UNSW for deployment to remote sites on the Antarctic Plateau including Dome A. The new facility will adopt many of the features of the AASTINO (Automated Astrophysical Site Testing InterNational Observatory) facility at Dome C. PLATO will autonomously control a flexible site testing and observing instrument suite, monitored via the Iridium satellite network. A challenging aspect of PLATO is to maximise the reliability of the power source while minimising fuel consumption. We are building a low pressure, low temperature environmental chamber to simulate operation at the highest altitudes (4,100 m at Dome A). Two types of engines will be tested: a single-cylinder diesel engine and a Stirling engine.

    2010-01-01

    The PLATO satellite mission project is a next generation ESA Cosmic Vision satellite project dedicated to the detection of exo-planets and to asteroseismology of their host-stars using ultra-high precision photometry. The main goal of the PLATO mission is to provide a full statistical analysis of exo-planetary systems around stars that are bright and close enough for detailed follow-up studies. Many aspects concerning the design trade-off of a space-based instrument and its performance can best be tackled through realistic simulations of the expected observations. The complex interplay of various noise sources in the course of the observations made such simulations an indispensable part of the assessment study of the PLATO Payload Consortium. We created an end-to-end CCD simulation software-tool, dubbed PLATOSim, which simulates photometric time-series of CCD images by including realistic models of the CCD and its electronics, the telescope optics, the stellar field, the pointing uncertainty of the satellite ...

    The majority of work on computer use in the dental field has focused on non-clinical practice management information needs. Very few computer-based dental information systems provide management support of the clinical care process, particularly with respect to quality management. Traditional quality assurance methods rely on the paper record and provide only retrospective analysis. Today, proactive quality management initiatives are on the rise. Computer-based dental information systems are being integrated into the care environment, actively providing decision support as patient care is being delivered. These new systems emphasize assessment and improvement of patient care at the time of treatment, thus building internal quality management into the caregiving process. The integration of real time quality management and patient care will be expedited by the introduction of an information system architecture that emulates the gathering and storage of clinical care data currently provided by the paper record. As a proposed solution to the problems associated with existing dental record systems, the computer-based patient record has emerged as a possible alternative to the paper dental record. The Institute of Medicine (IOM) recently conducted a study on improving the efficiency and accuracy of patient record keeping. As a result of this study, the IOM advocates the development and implementation of computer-based patient records as the standard for all patient care records. This project represents the ongoing efforts of The University of Iowa College of Dentistry's collaboration with the University of Uppsala Data Center, Uppsala, Sweden, on a computer-based patient dental record model. ICOHR (Intelligent Computer Based Oral Health Record) is an information system which brings together five important parts of the patient's dental record: medical and dental history; oral status; treatment planning; progress notes; and a Patient Care Database, generated from their

    Vanita, Ruth

    2010-01-01

    This article places Woolf in the context of homoerotic literary ancestry. It suggests that the overall argument in A Room of One's Own owes a debt to Wilde's 1891 pamphlet The Soul of Man under Socialism. It also examines Woolf's controversial meditation on male-female collaboration and intercourse in A Room, and suggests a homoerotic reading of this meditation, drawing on images and ideas of literary transmission and creation from Plato's Symposium.

    2015-01-01

    According to a previously published theory, Socrates was afflicted with temporal lobe epilepsy since his childhood. Plato, Xenophon, and Aristoxenus described Socrates as having exophthalmos, probably diplopia, and some symptoms compatible with hyperthyroidism. Using these data, we theorize that Socrates had Graves' disease. In order to determine a cause of his temporal lobe epilepsy, we speculate that the philosopher also had autoimmune thyroiditis and Hashimoto encephalopathy during his childhood and his epilepsy may have been a sequel to this hypothesized encephalopathy.

    PLATO 2.0 has been selected by ESA as the third medium-class Mission (M3) of the Cosmic Vision Program. Its Payload is conceived for the discovery of new transiting exoplanets on the disk of their parent stars and for the study of planetary system formation and evolution as well as to answer fundamental questions concerning the existence of other planetary systems like our own, including the presence of potentially habitable new worlds. The PLATO Payload design is based on the adoption of four sets of short focal length telescopes having a large field of view in order to exploit a large sky coverage and to reach, at the same time, the needed photometry accuracy and signalto- noise ratio (S/N) within a few tens of seconds of exposure time. The large amount of data produced by the telescope is collected and processed by means of the Payload's Data Processing System (DPS) composed by many processing electronics units. This paper gives an overview of the PLATO 2.0 DPS, mainly focusing on the architecture and processing capabilities of its Instrument Control Unit (ICU), the electronic subsystem acting as the main interface between the Payload (P/L) and the Spacecraft (S/C).

    Full Text Available This communication, through couple of studies driven since 10 years, tries to show how important is the training of authors in Computer Based Training (CBT. We submit here an approach to prepare designers mastering Interactive Multimedia modules in this domain. Which institutions are really dedicating their efforts in training authors and designers in this area of CBTs? Television devices and broadcast organisations offered since year 60s' a first support for Distance Learning. New media, New Information and Communication Technologies (NICT allowed several public and private organisations to start Distance Learning projects. As usual some of them met their training objectives, other of them failed. Did their really failed? Currently, nobody has the right answer. Today, we do not have enough efficient tools allowing us to evaluate trainees' acquisition in a short term view. Training evaluation needs more than 10 to 20 years of elapsed time to bring reliable measures. Nevertheless, given the high investments already done in this area, we cannot wait until the final results of the pedagogical evaluation. A lot of analyses showed relevant issues which can be used as directions for CBTs authors and designers training. Warning - Our studies and the derived conclusions are mainly based on projects driven in the field. We additionally bring our several years experience in the training of movie film authors in the design of interactive multimedia products. Some of our examples are extracting from vocational training projects where we were involved in all development phases from the analysis of needs to the evaluation of the acquisition within the trainee's / employee job's. Obviously, we cannot bring and exhaustive approach in this domain where a lot of parameters are involved as frame for the CBT interactive multimedia modules authors' and designers' training.

    The sonic aspects of Plato's analogy of the cave is taken as a starting point for thought experiments to investigate the objective nature of sound, and the idea of quasi-Platonic forms in music. Sounds are found to be objects in a way that sights or appearances are not, and it is only in the presence of technology that they become artificial. When recognition, control and communication about sound come into play, abstract concepts emerge, but there is no reason to give these the priority stat...

  17. Philosophy and Mathematics in the Teaching of Plato: the Development of Idea and Modernity

    Directory of Open Access Journals (Sweden)

    Mikhailova N. V.

    2014-01-01

    Full Text Available It is well known that the largest philosophers differently explain the origin of mathematics. This question was investigated in antiquity, a substantial and decisive role in this respect was played by the Platonic doctrine. Therefore, discussing this issue the problem of interaction of philosophy and mathematics in the teachings of Plato should be taken into consideration. Many mathematicians believe that abstract mathematical objects belong in a certain sense to the world of ideas and that consistency of objects and theories really describes mathematical reality, as Plato quite clearly expressed his views on math, according to which mathematical concepts objectively exist as distinct entities between the world of ideas and the world of material things. In the context of foundations of mathematics, so called “Gödel’s Platonism” is of particular interest. It is shown in the article how Platonic objectification of mathematical concepts contributes to the development of modern mathematics by revealing philosophical understanding of the nature of abstraction. To substantiate his point of view, the author draws the works of contemporary experts in the field of philosophy of mathematics.

    Many aspects of the design trade-off of a space-based instrument and its performance can best be tackled through simulations of the expected observations. The complex interplay of various noise sources in the course of the observations make such simulations an indispensable part of the assessment and design study of any space-based mission. We present a formalism to model and simulate photometric time series of CCD images by including models of the CCD and its electronics, the telescope optics, the stellar field, the jitter movements of the spacecraft, and all important natural noise sources. This formalism has been implemented in a versatile end-to-end simulation software tool, called PLATO Simulator, specifically designed for the PLATO space mission to be operated from L2, but easily adaptable to similar types of missions. We provide a detailed description of several noise sources and discuss their properties, in connection with the optical design, the allowable level of jitter, the quantum efficiency of th...

    2017-07-01

    With the current worldwide workforce shortage of Speech-Language Pathologists, new and innovative ways of delivering therapy to children with speech sound disorders are needed. Computer-based speech therapy may be an effective and viable means of addressing service access issues for children with speech sound disorders. To evaluate the efficacy of computer-based speech therapy programs for children with speech sound disorders. Studies reporting the efficacy of computer-based speech therapy programs were identified via a systematic, computerised database search. Key study characteristics, results, main findings and details of computer-based speech therapy programs were extracted. The methodological quality was evaluated using a structured critical appraisal tool. 14 studies were identified and a total of 11 computer-based speech therapy programs were evaluated. The results showed that computer-based speech therapy is associated with positive clinical changes for some children with speech sound disorders. There is a need for collaborative research between computer engineers and clinicians, particularly during the design and development of computer-based speech therapy programs. Evaluation using rigorous experimental designs is required to understand the benefits of computer-based speech therapy. The reader will be able to 1) discuss how computerbased speech therapy has the potential to improve service access for children with speech sound disorders, 2) explain the ways in which computer-based speech therapy programs may enhance traditional tabletop therapy and 3) compare the features of computer-based speech therapy programs designed for different client populations.

    We discuss collaborative problem solving computer-based recitation style. The course is designed by Lee [1], and the idea was proposed before by Christian, Belloni and Titus [2,3]. The students find the problems on a web-page containing simulations (physlets) and they write the solutions on an accompanying worksheet after discussing it with a classmate. Physlets have the advantage of being much more like real-world problems than textbook problems. We also compare two protocols for web-based instruction using simulations in an introductory physics class [1]. The inquiry protocol allowed students to control input parameters while the worked example protocol did not. We will discuss which of the two methods is more efficient in relation to Scientific Discovery Learning and Cognitive Load Theory. 1. Lee, Kevin M., Nicoll, Gayle and Brooks, Dave W.

    Full Text Available Constatando la importante influencia que el modelo pedagógico espartano ha ejercido a lo largo de la historia de la educación, los autores rastrean las huellas de esta ascendencia en tres momentos históricos: en la filosofía platónica, en la teoría política de Rousseau y en el estatalismo jacobino de la Revolución Francesa. De conformidad con el ejemplo de una austera e idealizada Esparta, cuajará —en cada uno de los momentos históricos referidos— la idea de celebrar fiestas públicas —de marcado carácter cívico y social— con manifestaciones gimnásticas y deportivas. De esta manera las fiestas gimnásticas al aire libre también serán un magnífico instrumento para la educación político-social del pueblo.The autors have studied the important influence which the Spartan educational model has had in the long history of education, they have traced this development in three historical moments: in Platonic philosophy, in the political theories of Rousseau and in Jacobin period during the French Revolution.

  10. The Theory of Argumentation within Language and its relation to Plato, Saussure and Benveniste

    Directory of Open Access Journals (Sweden)

    Cristiane Dall'Cortivo-Lebler

    2014-12-01

    Full Text Available The Theory of Argumentation within Language, developed by Oswald Ducrot, Jean-Claude Anscombre and Marion Carel, has experienced along its development different phases and forms, constantly seeking to align to what its main developer, Oswald Ducrot, called external hypotheses and internal hypotheses. This paper discusses the presence of Linguistic Theories and Philosophy in Ducrot’s work regarding concepts of Plato, Ferdinand de Saussure and Émile Benveniste, which constitute its external assumptions. The presence of these concepts culminated in the creation of different concepts that comprise the Linguistic Semantics, and gave it a specific point of view about language that emphasizes the internal relationships among language components and understands that speech is the result of a linguistic activity where an “I” speaks to a “you”.

  11. Efficient methods for solving discrete topology design problems in the PLATO-N project

    DEFF Research Database (Denmark)

    Canh, Nam Nguyen; Stolpe, Mathias

    This paper considers the general multiple load structural topology design problems in the framework of the PLATO-N project. The problems involve a large number of discrete design variables and were modeled as a non-convex mixed 0–1 program. For the class of problems considered, a global...... optimization method based on the branch-and-cut concept was developed and implemented. In the method a large number of continuous relaxations were solved. We also present an algorithm for generating cuts to strengthen the quality of the relaxations. Several heuristics were also investigated to obtain efficient...... algorithms. The branch and cut method is used to solve benchmark examples which can be used to validate other methods and heuristics....

  12. Alternative communication network designs for an operational Plato 4 CAI system

    Mobley, R. E., Jr.; Eastwood, L. F., Jr.

    1975-01-01

    The cost of alternative communications networks for the dissemination of PLATO IV computer-aided instruction (CAI) was studied. Four communication techniques are compared: leased telephone lines, satellite communication, UHF TV, and low-power microwave radio. For each network design, costs per student contact hour are computed. These costs are derived as functions of student population density, a parameter which can be calculated from census data for one potential market for CAI, the public primary and secondary schools. Calculating costs in this way allows one to determine which of the four communications alternatives can serve this market least expensively for any given area in the U.S. The analysis indicates that radio distribution techniques are cost optimum over a wide range of conditions.

  13. Banishing the Poet: The Pedagogical Function of Mythology in the Dialogues of Plato

    Directory of Open Access Journals (Sweden)

    Javier Martínez

    2013-06-01

    Full Text Available This text attempts to develop a sound justification for Plato’s pedagogical use of myth in the dialogues. In particular, I seek to resolve a seeming contradiction: why Plato personally made use of myths in spite of his many statements that seem to contradict such a pedagogical approach, especially his edict that poets and myth-makers be banished from his republic for the danger their works pose to the attainment of true philosophical wisdom. An analysis of the centrality of myths to the dialogues is carried out, followed by a discussion of the place of muthos in its Ionian historical context. This establishes the basis for resolving the contradiction through the division of muthos into two distinct modes: the fantastic and the eikastic.

  16. Interactive, Computer-Based Training Program for Radiological Workers

    Energy Technology Data Exchange (ETDEWEB)

    2000-01-18

    Lawrence Livermore National Laboratory (LLNL) is redesigning its Computer-Based Training (CBT) program for radiological workers. The redesign represents a major effort to produce a single, highly interactive and flexible CBT program that will meet the training needs of a wide range of radiological workers--from researchers and x-ray operators to individuals working in tritium, uranium, plutonium, and accelerator facilities. The new CBT program addresses the broad diversity of backgrounds found at a national laboratory. When a training audience is homogeneous in terms of education level and type of work performed, it is difficult to duplicate the effectiveness of a flexible, technically competent instructor who can tailor a course to the express needs and concerns of a course's participants. Unfortunately, such homogeneity is rare. At LLNL, they have a diverse workforce engaged in a wide range of radiological activities, from the fairly common to the quite exotic. As a result, the Laboratory must offer a wide variety of radiological worker courses. These include a general contamination-control course in addition to radioactive-material-handling courses for both low-level laboratory (i.e., bench-top) activities as well as high-level work in tritium, uranium, and plutonium facilities. They also offer training courses for employees who work with radiation-generating devices--x-ray, accelerator, and E-beam operators, for instance. However, even with the number and variety of courses the Laboratory offers, they are constrained by the diversity of backgrounds (i.e., knowledge and experience) of those to be trained. Moreover, time constraints often preclude in-depth coverage of site- and/or task-specific details. In response to this situation, several years ago LLNL began moving toward computer-based training for radiological workers. Today, that CBT effort includes a general radiological safety course developed by the Department of Energy's Hanford facility and

    To evaluate the outcome of training both urological novices and experts, using the recently developed UroMentor (Simbionix Ltd, Israel) trainer, that provides a realistic simulation of rigid and flexible ureterorenoscopy (URS). Twenty experienced urologists (total number of previous flexible URSs 21-153) were monitored during simulated flexible URS for treating a lower calyceal stone, and the outcome was correlated with individual experience. A score was compiled based on the variables recorded, including total operation time, stone contact time, complications such as bleeding or perforation, and treatment success. A further five urological residents with no endourological experience were trained on the UroMentor in rigid URS for ureteric stone treatment. Their acquired clinical skills were subsequently compared to those of five urological residents who received no simulator training. All 20 experienced urologists disintegrated the stone on the simulator, and the score achieved was related to their personal experience; there was a significant difference in performance in those with 80 previous flexible URSs. For the five urological residents with no endourological experience, simulator training improved their skills, and comparison with urological residents who had received no simulator training showed advantages for the trained residents. After being trained on the simulator, the group performed better in the first four URSs on patients. Individual experience correlates with individual performance on the simulator. Simulator training was helpful in improving clinical skills. Although the distribution of computer-based simulators is limited by high prices, virtual reality-based training has the potential to become an important tool for clinical education.

    PLATO is a prototype hybrid X-ray photon counting detector that has been designed to meet the specifications for plasma diagnostics for the WEST tokamak platform (Tungsten (W) Environment in Steady-state Tokamak) in southern France, with potential perspectives for ITER. PLATO represents a customized solution that fulfills high sensitivity, low dispersion and high photon counting rate. The PLATO prototype matrix is composed of 16 × 18 pixels with a 70 μm pixel pitch. New techniques have been used in analog sensitive blocks to minimize noise coupling through supply rails and substrate, and to suppress threshold dispersion across the matrix. The PLATO ASIC is designed in CMOS 0.13 μm technology and was submitted for a fabrication run in June 2016. The chip is designed to be bump-bonded to a silicon sensor. This paper presents pixel architecture as well as simulation results while highlighting novel solutions.

    2014-01-01

    This study was undertaken in the planning phase for the introduction of a comprehensive computer based nursing documentation system at Erlangen University Hospital. There, we expect a wide range of difficult organizational changes, because the nurses currently neither used computer based nursing documentation nor did they follow strongly the nursing process model within paper based documentation. Thus we were eager to recognize potential pitfalls early and to identify potential barriers for digital nursing documentation. In a questionnaire study we surveyed all German university hospitals for their experience with the implementation of computer based nursing documentation implementation. We received answers from 11 of the 23 hospitals. Furthermore we performed a questionnaire study about expectations and fears among the nurses of four pilot wards of our hospital. Most respondents stated a positive attitude towards the nursing process documentation, but many respondents note technical (e.g. bad performance of the software) and organizational barriers (e.g. lack of time).

    1998-03-01

    The traditional approach to delivering radiation safety training has been to provide a stand-up lecture of the topic, with the possible aid of video, and to repeat the same material periodically. New approaches to meeting training requirements are needed to address the advent of flexible work hours and telecommuting, and to better accommodate individuals learning at their own pace. Computer- based and web-based radiation safety training can provide this alternative. Computer-based and web- based training is an interactive form of learning that the student controls, resulting in enhanced and focused learning at a time most often chosen by the student.

  20. Establishing performance requirements of computer based systems subject to uncertainty

    Energy Technology Data Exchange (ETDEWEB)

    Robinson, D.

    1997-02-01

    An organized systems design approach is dictated by the increasing complexity of computer based systems. Computer based systems are unique in many respects but share many of the same problems that have plagued design engineers for decades. The design of complex systems is difficult at best, but as a design becomes intensively dependent on the computer processing of external and internal information, the design process quickly borders chaos. This situation is exacerbated with the requirement that these systems operate with a minimal quantity of information, generally corrupted by noise, regarding the current state of the system. Establishing performance requirements for such systems is particularly difficult. This paper briefly sketches a general systems design approach with emphasis on the design of computer based decision processing systems subject to parameter and environmental variation. The approach will be demonstrated with application to an on-board diagnostic (OBD) system for automotive emissions systems now mandated by the state of California and the Federal Clean Air Act. The emphasis is on an approach for establishing probabilistically based performance requirements for computer based systems.

    2003-02-01

    As is the case with most developed countries, pressures from various sectors of society have seen computers make a big presence in Australian education systems in the last decade. In the state of Victoria, integrating learning technology (LT) into all key learning areas of every school's curriculum has been a priority policy of governments. Over the last 8-10 years, large amounts of money have been provided to set schools up with computers and associated technologies. In the area of science, a range of LT resources is available for use in the teaching and learning processes in the classroom. However, there has been limited evaluation into teachers' attitudes towards, and types of, methodology and effectiveness of usage of computer-based technologies in knowledge construction. Using both quantitative and qualitative methods, a study aimed at identifying science teachers' opinions and practices with the use of computer-based technologies in their teaching has been carried out in Victorian government schools. The focus of this paper is on the attitudes of these science teachers towards the use of computer-based technologies in their teaching. The study showed that most teachers have embraced the introduction of these technologies into the school structure well and are generally positive about their potential in the classroom. However, their use in the classrooms is infrequent and often on an ad hoc basis. A range of obstacles preventing the use of these technologies are identified and discussed in this paper.

    (67 participants completed computer-based interventions; 92 participants completed in-person interventions). Workers were primarily white, Caucasian, middle-aged, and college-educated. Both studies delivered education about stress, its causes, and strategies to reduce stress (e.g. relaxation or mindfulness) via a computer in the computer-based arm, and via small group sessions in the in-person arm. Both studies measured stress using different scales at short-term follow-up only (less than one month). Due to considerable heterogeneity in the results, we could not pool the data, and we analysed the results of the studies separately. The SMD of stress levels in the computer-based intervention group was 0.81 standard deviations higher (95% CI 0.21 to 1.41) than the in-person group in one study, and 0.35 standard deviations lower (95% CI -0.76 to 0.05) than the in-person group in another study. We judged both studies as having a high risk of bias. We found very low-quality evidence with conflicting results, when comparing the effectiveness of computer-based stress management interventions with in-person stress management interventions in employees. We could include only two studies with small sample sizes. We have very little confidence in the effect estimates. It is very likely that future studies will change these conclusions.

  6. From Pericles to Plato – from democratic political praxis to totalitarian political philosophy

    Full Text Available Plato is normally taken as one of the founders of Western political philosophy, not at least with his Republic. Here, he constructs a hierarchy of forms of governments, beginning with aristocracy at the top as a critical standard for the other forms of governments, and proceeding through timocracy and oligarchy to democracy and tyranny at the bottom. Following Karl Popper, the paper argues that Plato’s is a totalitarian philosophy that emphasizes the similarities between democracy and tyranny, which it considers to be the two worst forms of government. Plato’s denigration of democracy has dominated the tradition of political philosophy until recent times. This paper, however, shows that political philosophy in fact originates in democracy, especially as developed by the sophists and that philosophy is only a form of sophism with a similar origin in ancient Greek democracy. A discussion of Pericles’ funeral oration is used to show that Pericles presented a democratic political philosophy that can serve as a counterpoint to Plato’s political philosophy in the Republic.

    Full Text Available Objective: Clinical reasoning is usually taught using a problem-solving approach, which is widely adopted in medical education. However, learning through problem solving is difficult as a result of the contextualization and dynamic aspects of actual problems. Moreover, knowledge acquired from problem-solving practice tends to be inert and fragmented. This study proposed a computer-based cognitive representation approach that externalizes and facilitates the complex processes in learning clinical reasoning. The approach is operationalized in a computer-based cognitive representation tool that involves argument mapping to externalize the problem-solving process and concept mapping to reveal the knowledge constructed from the problems. Methods: Twenty-nine Year 3 or higher students from a medical school in east China participated in the study. Participants used the proposed approach implemented in an e-learning system to complete four learning cases in 4 weeks on an individual basis. For each case, students interacted with the problem to capture critical data, generate and justify hypotheses, make a diagnosis, recall relevant knowledge, and update their conceptual understanding of the problem domain. Meanwhile, students used the computer-based cognitive representation tool to articulate and represent the key elements and their interactions in the learning process. Results: A significant improvement was found in students’ learning products from the beginning to the end of the study, consistent with students’ report of close-to-moderate progress in developing problem-solving and knowledge-construction abilities. No significant differences were found between the pretest and posttest scores with the 4-week period. The cognitive representation approach was found to provide more formative assessment. Conclusions: The computer-based cognitive representation approach improved the learning of clinical reasoning in both problem solving and knowledge

    Tooth carving is an important practical preclinical exercise in the curriculum in Indian dental education setup. It forms the basis of introduction to tooth anatomy, morphology and occlusion of primary and permanent teeth through practical approach. It requires enormous time and manpower to master the skill. Therefore, there is an imminent necessity to incorporate computer-based learning of the art of tooth carving for effective teaching and efficient student learning. This will ensure quality time to be spent on other academic and research activities by students and faculty in addition to adding value as a teaching aid.

    2013-04-15

    Extreme rates of vascular and all-cause mortality especially in the clopidogrel arm of the Platelet Inhibition and Patient Outcomes (PLATO) non-USA cohort raise concerns of data integrity, and call for independent verification of vital records in the national death registries. Four recent acute coronary syndrome (ACS) trials: Thrombin Receptor Antagonist for Clinical Event Reduction in Acute Coronary Syndrome (TRACER), Anti-Xa therapy to lower cardiovascular events in addition to standard therapy in subjects with acute coronary syndrome (ATLAS-ACS 2), Trial to Assess Improvement in Therapeutic Outcomes by Optimizing Platelet Inhibition with Prasugrel (TRITON), and the Thrombin Receptor Antagonist in Secondary Prevention of Atherothrombotic Ischemic Events (TRA 2P), provide a valuable opportunity to match lost in follow-up (LIFU) with mortality rates among similar ACS studies. To compare the LIFU from PLATO, TRACER, ATLAS-ACS 2, TRITON-TIMI 38 and TRA 2P trials. The disturbingly high (8.9%-14.7%) LIFU in PLATO was no match to LIFU in TRACER (0.1%), ATLAS ACS 2 (0.3%), TRITON (0.1%) and TRA 2P (0.1%). In fact, such an astronomical (49-147 fold higher) PLATO LIFU rate should result in less mortality compared to the other ACS trials since no event can be reported or adjudicated if the patient has been lost. Adjusting LIFU rate revealed that vascular (5.55%) and all cause (6.05%) mortality in PLATO was even more disparate than in TRACER (3.2% and 4.9%), ATLAS-ACS 2 (4.1% and 4.5%), TRITON-TIMI 38 (2.4% and 3.2%) and TRA 2P (3.0% and 5.3%) control arms, respectfully. Moreover, the incomplete CV follow-up in the ATLAS ACS 2 trial was later revealed to be around 12%, which lead to the rejection of rivaroxaban for the treatment of ACS. PLATO's LIFU rate was just as high, if not higher, than seen in ATLAS ACS 2. The chance to die in PLATO far exceeds the mortality risks observed in the clopidogrel arms of four recent ACS trials, which becomes especially evident after

    Computer based Natural Language Processing (NLP) is the key to enabling humans and their computer based creations to interact with machines in natural language (like English, Japanese, German, etc., in contrast to formal computer languages). The doors that such an achievement can open have made this a major research area in Artificial Intelligence and Computational Linguistics. Commercial natural language interfaces to computers have recently entered the market and future looks bright for other applications as well. This report reviews the basic approaches to such systems, the techniques utilized, applications, the state of the art of the technology, issues and research requirements, the major participants and finally, future trends and expectations. It is anticipated that this report will prove useful to engineering and research managers, potential users, and others who will be affected by this field as it unfolds.

    Desaulniers, David R.; Gillan, Douglas J.; Rudisill, Marianne

    1988-01-01

    Two experiments were conducted to investigate display variables likely to influence the effectiveness of computer-based procedure displays. In experiment 1, procedures were presented in three formats, text, extended-text, and flowchart. Text and extended-text are structured prose formats which differ in the spatial density of presentation. The flowchart format differs from the text format in both syntax and spatial representation. Subjects were required to use the procedures to diagnose a hypothetical system anomaly. The results indicate that performance was most accurate with the flowchart format. In experiment 2, procedure window size was varied (6-line, 12-line, and 24-line) in addition to procedure format. In the six line window condition, experiment 2 replicated the findings of experiment 1. As predicted, completion times for flowchart procedures decreased with increasing window size; however, accuracy of performance decreased substantially. Implications for the design of computer-based procedure displays are discussed.

    Computer-based training (CBT) systems can efficiently support modern teaching and learning environments. In this paper, we demonstrate on the basis of the case-based CBT system CAMPUS that current learning theories and design principles (Bloom's Taxonomy and practice fields) are (i) relevant to CBT and (ii) are feasible to implement using computer-based training and adequate learning environments. Not all design principles can be fulfilled by the system alone, the integration of the system in adequate teaching and learning environments therefore is essential. Adequately integrated, CBT programs become valuable means to build or support practice fields for learners that build domain knowledge and problem-solving skills. Learning theories and their design principles can support in designing these systems as well as in assessing their value.

    In this paper a quantum computer based on the recombination processes happening in semiconductor devices is presented. A "data element" and a "computational element" are derived based on Schokley-Read-Hall statistics and they can later be used to manifest a simple and known quantum computing process. Such a paradigm is shown by the application of the proposed computer onto a well known physical system involving traps in semiconductor devices.

    The United States (U.S.) Department of Energy (DOE) is sponsoring research through the Light Water Reactor Sustainability (LWRS) program to extend the life of the currently operating fleet of commercial nuclear power plants. The Risk Informed Safety Margin Characterization (RISMC) research pathway within LWRS looks at ways to maintain and improve the safety margins of these plants. The RISMC pathway includes significant developments in the area of thermalhydraulics code modeling and the development of tools to facilitate dynamic probabilistic risk assessment (PRA). PRA is primarily concerned with the risk of hardware systems at the plant; yet, hardware reliability is often secondary in overall risk significance to human errors that can trigger or compound undesirable events at the plant. This report highlights ongoing efforts to develop a computation-based approach to human reliability analysis (HRA). This computation-based approach differs from existing static and dynamic HRA approaches in that it: (i) interfaces with a dynamic computation engine that includes a full scope plant model, and (ii) interfaces with a PRA software toolset. The computation-based HRA approach presented in this report is called the Human Unimodels for Nuclear Technology to Enhance Reliability (HUNTER) and incorporates in a hybrid fashion elements of existing HRA methods to interface with new computational tools developed under the RISMC pathway. The goal of this research effort is to model human performance more accurately than existing approaches, thereby minimizing modeling uncertainty found in current plant risk models.

    This study compares the dosimetric differences in HDR brachytherapy treatment plans calculated with Nucletron's PLATO and Oncentra MasterPlan treatment planning systems (TPS). Ten patients (1 T1b, 1 T2a, 6 T2b, 2 T4) having cervical carcinoma, median age of 43.5 years (range, 34-79 years) treated with tandem & ring applicator in our institution were selected retrospectively for this study. For both Plato and Oncentra TPS, the same orthogonal films anterior-posterior (AP) and lateral were used to manually draw the prescription and anatomical points using definitions from the Manchester system and recommendations from the ICRU report 38. Data input for PLATO was done using a digitizer and Epson Expression 10000XL scanner was used for Oncentra where the points were selected on the images in the screen. The prescription doses for these patients were 30 Gy to points right A (RA) and left A (LA) delivered in 5 fractions with Ir-192 HDR source. Two arrangements: one dwell position and two dwell positions on the tandem were used for dose calculation. The doses to the patient points right B (RB) and left B (LB), and to the organs at risk (OAR), bladder and rectum for each patient were calculated. The mean dose and the mean percentage difference in dose calculated by the two treatment planning systems were compared. Paired t-tests were used for statistical analysis. No significant differences in mean RB, LB, bladder and rectum doses were found with p-values > 0.14. The mean percent difference of doses in RB, LB, bladder and rectum are found to be less than 2.2%, 1.8%, 1.3% and 2.2%, respectively. Dose calculations based on the two different treatment planning systems were found to be consistent and the treatment plans can be made with either system in our department without any concern.

    2011-01-01

    Full Text Available Chemistry is a very comprehensive discipline that researches atoms; molecules; the structure of matter in the form of element or compound; combinations, and physical and chemical properties of matter; macroscopic and microscopic transformations of matters; the energy and entropy released or absorbed in the course of these transformations; the structures and functions of carbohydrates, lipids, proteins, enzymes, vitamins and minerals in the body. This discipline includes numerous reactions at the macroscopic, microscopic and particulate levels, abstract concepts, three-dimensional structure of molecules, mathematics, and graphics. It is important for students to be trained as scientists to internalize -with meaningful learning - chemistry having much abstract concepts. Especially for students in associate degree programs in Vocational High Schools, taking this integrated course will provide them to be more creative in their future professional work; to cope with and overcome analytical problems; to be self-learners; to fill the gaps concerning chemical analysis originated from secondary education; and to gain critical thinking and self-evaluation skills regarding chemical problems. In the age of developing science and technology, “Computer-Based Active Learning Method” emerged with the introduction of multi-media into education and training. In this context, students will learn difficult and complex mathematical operations and graphics interpretations more meaningfully with computer-based simulations and analogies.

    2008-01-01

    Full Text Available This article is a language-based re-reading of Plato's exile of the poets via Wallace Stevens' poem-manifesto, "An Ordinary Evening in New Haven." I examine how philosophy and poetry use language differently in order to deconstruct an origin of the speech-acts -- wonder -- that I then identify as a phenomenological difference between philosophers and poets. I contend that the thinking-into-language of philosophers is based in theoria, comprehension, and a resulting closure of wonder. I contrast this with the processes of poets, who I show to be moving thought into language via gnosis, apprehension, and a phenomenology opening onto inexhaustible wonder.

    What is love and what part does it play in psychoanalysis? Where are the analyst and the analysand situated in relation to the roles defined as those of the "lover" and the "beloved"? Jacques Lacan explores these and other questions in his soon-to-be-published Seminar VIII: Transference by providing an extensive commentary on Plato's most famous dialogue on love, the Symposium. This paper outlines some of the major points about love that grow out of Lacan's reading of the dialogue and examines their relevance to the analytic setting. Can the analyst be characterized as a sort of modern-day Socrates?

    Computer-based simulation has intuitive appeal to both educators and learners with the flexibility of time, place, immediate feedback, and self-paced and consistent curriculum. The purpose of this study was to assess the effects of computer-based simulation on nursing students' performance, self-efficacy, post-code stress, and satisfaction between computer-based simulation plus instructor-led cardiopulmonary resuscitation training group and instructor-led resuscitation training-only group. This study was a nonequivalent control group posttest-only design. There were 213 second year nursing students randomly assigned to one of two groups: 109 nursing students with computer-based simulation or 104 with control group. Overall nursing students' performance score was higher in the computer-based simulation group than in the control group but reached no statistical significance (t = 1.086, p = .283). There were no significant differences in resuscitation-specific self-efficacy, post-code stress, and satisfaction between the two groups. Computer-based simulation combined with hands-on practice did not affect in nursing students' performance, self-efficacy, post-code stress, and satisfaction in nursing students. Further study must be conducted to inform instructional design and help integrate computer-based simulation and rigorous scoring rubrics.

    Semantic cognition refers to our ability to use, manipulate and generalize knowledge that is acquired over the lifespan to support innumerable verbal and non-verbal behaviours. This Review summarizes key findings and issues arising from a decade of research into the neurocognitive and neurocomputational underpinnings of this ability, leading to a new framework that we term controlled semantic cognition (CSC). CSC offers solutions to long-standing queries in philosophy and cognitive science, and yields a convergent framework for understanding the neural and computational bases of healthy semantic cognition and its dysfunction in brain disorders.

    We propose a scheme of a quantum computer based on nanophotonic elements: two buses in the form of nanowaveguide resonators, two nanosized units of multiatom multiqubit quantum memory and a set of nanoprocessors in the form of photonic quantum transistors, each containing a pair of nanowaveguide ring resonators coupled via a quantum dot. The operation modes of nanoprocessor photonic quantum transistors are theoretically studied and the execution of main logical operations by means of them is demonstrated. We also discuss the prospects of the proposed nanophotonic quantum computer for operating in high-speed optical fibre networks. (quantum computations)

  17. The micro-fascism of Plato's good citizen: producing (dis)order through the construction of risk.

    2007-04-01

    The human body has come to be seen as forever susceptible to both external and internal hazards, which in many circumstances require immediate, heroic, and expensive intervention. In response to this, there has been a shift from a treatment-based healthcare model to one of prevention wherein nurses play an integral role by identifying and assessing risks for individuals, communities, and populations. This paper uses Deborah Lupton's outline of the spectrum of risk and applies the theoretical works of Foucault and Plato to demonstrate the means by which nurses maintain social order by identifying and counselling risk takers. It also utilizes the work of Deleuze and Guattari to illustrate how Plato's framework for creating social order through the creation of the good citizen can be viewed as a micro-fascist system, which has been adopted wholeheartedly by preventative health professionals. The goal of this paper is to present an alternate understanding of risk to provide nurses and other healthcare professionals with a non-traditional appreciation of certain aspects of their practice as researchers and clinicians.

    Full Text Available Platão, ao tratar da negação no diálogo Sofista, afirma que sempre que enunciamos o que não é, não enunciamos algo contrário ao que é, mas algo diferente. A negação significa cada parte da natureza da diferença em antítese ao que é. Tal tratamento da negação resulta da necessidade de resolver alguns problemas colocados pelo eleatismo. Propõe-se indicar esses problemas e examinar o tratamento que Platão dá ao não-ser como diferença.Plato, in dealing with negation in the dialogue Sophist, says that when we say what is not, we speak not of something that is the opposite of being, but of something different. Negation means each part of the nature of the difference in antithesis to what is. This treatment of negation results from the need to solve some problems posed by eleatism. It is proposed to indicate these problems and examine the treatment that Plato gives to non-being as difference.

    Full Text Available Describing and explaining the nature of imagination and its function with regard to human being and ontology has always been one of the preoccupations of philosophers and thinkers. Plato is the first philosopher who considered an epistemological status for imagination and, by dividing the world into the world of reason and world of senses, he ascribed the knowledge of imagination to the world of senses. In different parts of Mathnavi, Molavi, the great Muslim-Iranian mystic, has paid much attention to imagination, its types, its status in the Knowledge of Man (both physical and metaphysical affairs and its various influences on the body, soul and mental states of any individual. Thus, the present article aims to compare the concept of imagination in the view of the two thinkers. For reaching such aim, while using a descriptive-comparative method, first, the definitions of imagination in Mathnavi and Plato’s ideas are investigated and, then, the similarities and differences of the two views are shown. The conclusion is that their ideas are similar with regard to unreality and shadowiness of the world and phenomena, the relation between imitation and imagination, deficiency and restrictions of imagination for understanding the reality, whereas their ideas are different regarding the power of imagination, its epistemological status and the meaning and influence of it.

    2012-01-01

    Background Due to the great variability of 12-lead ECG instruments and medical specialists’ interpretation skills, it remains a challenge to deliver rapid and accurate 12-lead ECG reports with senior cardiologists’ decision making support in emergency telecardiology. Methods We create a new cloud and pervasive computing based 12-lead Electrocardiography (ECG) service to realize ubiquitous 12-lead ECG tele-diagnosis. Results This developed service enables ECG to be transmitted and interpreted via mobile phones. That is, tele-consultation can take place while the patient is on the ambulance, between the onsite clinicians and the off-site senior cardiologists, or among hospitals. Most importantly, this developed service is convenient, efficient, and inexpensive. Conclusions This cloud computing based ECG tele-consultation service expands the traditional 12-lead ECG applications onto the collaboration of clinicians at different locations or among hospitals. In short, this service can greatly improve medical service quality and efficiency, especially for patients in rural areas. This service has been evaluated and proved to be useful by cardiologists in Taiwan. PMID:22838382

    2015-09-01

    To develop a computer-based single sentence reading test especially designed for clinical research enabling multiple repeat trials without reusing the same sentences. We initially developed 422 sentences, with an average of 60 characters and 12 words. Presentation controls were improved by employing computer-based testing and the oral reading was recorded by visual inspection of digital audio recordings. Variability in reading speed of normally sighted adults between sentences, between charts, between subjects, between formats, and between display devices was quantified. The impact of display size and pixel resolution on test geometry was assessed, and the impact of reduced retinal image quality and retinal illuminance were compared for reading and standard letter acuities. Eleven visually normal subjects (age: 18-60 years) participated in this study. Stopwatch timing of sentences reliably underestimated reading times by about 0.3 s, and exhibited coefficients of repeatability 17 times larger than those estimated from visual inspection of digital recordings. A slight relaxing of the lexical content constraints had no effect on reading speed; neither did sentence format (single vs three lines) or display size or distance. Within subject standard deviations of reading speed for different sentences were small (between 6% and 9% of the mean speed) requiring only small samples sizes to achieve typical statistical reliability and power when comparing conditions within individual subjects. The greater variability associated with stopwatch timing necessitates larger sample sizes. As defocus and light level were varied, reading acuity and standard letter acuity were highly correlated (r(2)  = 0.99), and reading acuity was slightly better. A computer-based IURead reading test provides a useful reading speed and reading acuity tool for clinical research involving multiple conditions and repeat testing of individual subjects.

    Many organizations and institutions around the globe are moving or planning to move their paper-and-pencil based testing to computer-based testing (CBT). However, this conversion will not be the best option for all kinds of exams and it will require significant resources. These resources may include the preparation of item banks, methods for test delivery, procedures for test administration, and last but not least test security. Security aspects may include but are not limited to the identification and authentication of examinee, the risks that are associated with cheating on the exam, and the procedures related to test delivery to the examinee. This paper will mainly investigate the security considerations associated with CBT and will provide some recommendations for the security of these kinds of tests. We will also propose a palm-based biometric authentication system incorporated with basic authentication system (username/password) in order to check the identity and authenticity of the examinee.

  12. A Computationally Based Approach to Homogenizing Advanced Alloys

    Energy Technology Data Exchange (ETDEWEB)

    Jablonski, P D; Cowen, C J

    2011-02-27

    We have developed a computationally based approach to optimizing the homogenization heat treatment of complex alloys. The Scheil module within the Thermo-Calc software is used to predict the as-cast segregation present within alloys, and DICTRA (Diffusion Controlled TRAnsformations) is used to model the homogenization kinetics as a function of time, temperature and microstructural scale. We will discuss this approach as it is applied to both Ni based superalloys as well as the more complex (computationally) case of alloys that solidify with more than one matrix phase as a result of segregation. Such is the case typically observed in martensitic steels. With these alloys it is doubly important to homogenize them correctly, especially at the laboratory scale, since they are austenitic at high temperature and thus constituent elements will diffuse slowly. The computationally designed heat treatment and the subsequent verification real castings are presented.

    WhistleSoft is developing a set of computer-based, self-paced tutorials on particle accelerators that targets a broad audience, including undergraduate science majors and industrial technicians. (See http://www.whistlesoft.com/s~ilbar/.) We use multimedia techniques to enhance the student's rate of learning and retention of the material. The tutorials feature interactive On-Screen Laboratories and use hypertext, colored graphics, two- and three-dimensional animations, video, and sound. Parts of our Dipoles module deal with the double-focusing spectrometer and occur throughout the piece. Radial focusing occurs in the section on uniform magnets, while vertical focusing is in the non-uniform magnets section. The student can even understand the √2π bend angle on working through the (intermediate-level) discussion on the Kerst-Serber equations. This talk will present our discussion of this spectrometer, direct to you from the computer screen.

    In Norway, organizational changes in hospitals and a stronger focus on patient safety have changed the way of organizing and managing paper based patient records. Hospital-wide patient records tend to replace department based records. Since not only clinicians, but also other non-medical staff have access to the paper records, they also have easy access to all the information which is available on a specific patient; such a system has obvious 'side effects' on privacy and security. Computer based patient records (CPRs) can provide the solution to this apparent paradox if the complex aspects of security, privacy, effectiveness, and user friendliness are focused on jointly from the outset in designing such systems. Clinical experiences in Norway show that it is possible to design patient record systems that provide a very useful tool for clinicians and other health care personnel (HCP) while fully complying with comprehensive security and privacy requirements.

    Reservoir computing is a new bio-inspired computation paradigm. It exploits a dynamical system driven by a time-dependent input to carry out computation. For efficient information processing, only a few parameters of the reservoir needs to be tuned, which makes it a promising framework for hardware implementation. Recently, electronic, opto-electronic and all-optical experimental reservoir computers were reported. In those implementations, the nonlinear response of the reservoir is provided by active devices such as optoelectronic modulators or optical amplifiers. By contrast, we propose here the first reservoir computer based on a fully passive nonlinearity, namely the saturable absorption of a semiconductor mirror. Our experimental setup constitutes an important step towards the development of ultrafast low-consumption analog computers.

    The Computer-Based Procedure (CBP) research effort is a part of the Light-Water Reactor Sustainability (LWRS) Program, which provides the technical foundations for licensing and managing the long-term, safe, and economical operation of current nuclear power plants. One of the primary missions of the LWRS program is to help the U.S. nuclear industry adopt new technologies and engineering solutions that facilitate the continued safe operation of the plants and extension of the current operating licenses. One area that could yield tremendous savings in increased efficiency and safety is in improving procedure use. A CBP provides the opportunity to incorporate context-driven job aids, such as drawings, photos, and just-in-time training. The presentation of information in CBPs can be much more flexible and tailored to the task, actual plant condition, and operation mode. The dynamic presentation of the procedure will guide the user down the path of relevant steps, thus minimizing time spent by the field worker to evaluate plant conditions and decisions related to the applicability of each step. This dynamic presentation of the procedure also minimizes the risk of conducting steps out of order and/or incorrectly assessed applicability of steps. This report provides a summary of the main research activities conducted in the Computer-Based Procedures for Field Workers effort since 2012. The main focus of the report is on the research activities conducted in fiscal year 2016. The activities discussed are the Nuclear Electronic Work Packages – Enterprise Requirements initiative, the development of a design guidance for CBPs (which compiles all insights gained through the years of CBP research), the facilitation of vendor studies at the Idaho National Laboratory (INL) Advanced Test Reactor (ATR), a pilot study for how to enhance the plant design modification work process, the collection of feedback from a field evaluation study at Plant Vogtle, and path forward to

    Strategies of presenting instructional information affect the type of cognitive load imposed on the learner's working memory. Effective instruction reduces extraneous (ineffective) cognitive load and promotes germane (effective) cognitive load. Eighty first-year students from two veterinary schools completed a two-section questionnaire that evaluated their perspectives on the educational value of a computer-based instructional program. They compared the difference between cognitive loads imposed by paper-based and computer-based instructional strategies used to teach the anatomy of the canine skeleton. Section I included 17 closed-ended items, rated on a five-point Likert scale, that assessed the use of graphics, content, and the learning process. Section II included a nine-point mental effort rating scale to measure the level of difficulty of instruction; students were asked to indicate the amount of mental effort invested in the learning task using both paper-based and computer-based presentation formats. The closed-ended data were expressed as means and standard deviations. A paired t test with an alpha level of 0.05 was used to determine the overall mean difference between the two presentation formats. Students positively evaluated their experience with the computer-based instructional program with a mean score of 4.69 (SD=0.53) for use of graphics, 4.70 (SD=0.56) for instructional content, and 4.45 (SD=0.67) for the learning process. The mean difference of mental effort (1.50) between the two presentation formats was significant, t=8.26, p≤.0001, df=76, for two-tailed distribution. Consistent with cognitive load theory, innovative computer-based instructional strategies decrease extraneous cognitive load compared with traditional paper-based instructional strategies.

    Computer-based systems (CBS) can provide information to help individuals analyze their health care needs and make decisions about management of health problems. This article discusses the development of a CBS that delivers an individualized educational intervention for continence health promotion. System development included cycles of prototype design, testing, analysis, and redesign. Knowledge acquisition, representation methods, and design decisions are discussed. Participants completed 4 rounds of usability testing and a pilot test, which resulted in enhancements to both the CBS and the expert system feature that produced individualized feedback. This iterative design process involved users throughout system development. User involvement resulted in a tutorial to explain navigation and other features of the CBS, graphics to enhance the written message, and clarification of continence-related content. The procedures resulted in an informative, usable product; they can be used to develop systems that provide information about symptom self-management for other health conditions.

    2010-04-01

    Full Text Available This paper, drawing on a research project concerning the educational use of digital mind games with primary school students, aims at giving a contribution to the understanding of which are the main factors influencing student motivation during computer-based learning activities. It puts forward some ideas and experience based reflections, starting by considering digital games that are widely recognized as the most promising ICT tools to enhance student motivation. The project results suggest that student genuine engagement in learning activities is mainly related to the actual possession of the skills and of the cognitive capacities needed to perform the task. In this perspective, cognitive overload should be regarded as one of the main reasons contributing to hinder student motivation and, consequently, should be avoided. Other elements such as game attractiveness and experimental setting constraints resulted to have a lower effect on student motivation.

    Weisman, Melanie

    1988-02-01

    As newer and more sophisticated imagery collection systems rapidly increase the volume of imagery requiring thorough exploitation, the need for imagery analysts to acquire and maintain expertise increases accordingly. In response, Loral Systems Group (Arizona) has produced a computer-based-training (CBT) system that presents a series of lessons on radar imaging principles and their application to the various orders of battle. The training system is composed of two host computers, four student/instructor workstations, a printer, and lesson material. The computers control the imagery presentation, deliver twenty-eight interactive lessons of computer-assisted instruction, and generate reports. Each dual-screen workstation presents lessons consisting of instructional text coupled with representative imagery annotated with color graphics. Although the system is designed for the unique characteristics of radar interpretation, alternative courseware could instruct interpretation techniques for other imagery (photographic, electro-optical, infrared). Regardless of the sensor type and amount of available imagery, both commercial and military segments of the interpretation community will benefit only if the interpreter/analyst is successfully trained to translate image information into useful terms.

    2014-09-01

    Reflecting the common use of the MMPI-2 to provide diagnostic considerations, computer-based test interpretations (CBTIs) also typically offer diagnostic suggestions. However, these diagnostic suggestions can sometimes be shown to vary widely across different CBTI programs even for identical MMPI-2 profiles. The present study evaluated the diagnostic reliability of 6 commercially available CBTIs using a 20-item Q-sort task developed for this study. Four raters each sorted diagnostic classifications based on these 6 CBTI reports for 20 MMPI-2 profiles. Two questions were addressed. First, do users of CBTIs understand the diagnostic information contained within the reports similarly? Overall, diagnostic sorts of the CBTIs showed moderate inter-interpreter diagnostic reliability (mean r = .56), with sorts for the 1/2/3 profile showing the highest inter-interpreter diagnostic reliability (mean r = .67). Second, do different CBTIs programs vary with respect to diagnostic suggestions? It was found that diagnostic sorts of the CBTIs had a mean inter-CBTI diagnostic reliability of r = .56, indicating moderate but not strong agreement across CBTIs in terms of diagnostic suggestions. The strongest inter-CBTI diagnostic agreement was found for sorts of the 1/2/3 profile CBTIs (mean r = .71). Limitations and future directions are discussed.

  6. Social psychology: new directions in computer-based learning

    Lesley J. Allinson

    1996-12-01

    Full Text Available Perhaps surprisingly, psychology has been a discipline eager to capitalize on the application of computers for teaching. Traditionally, this has been for statistical calculations, and the presentation of experimental stimuli and the automatic collection of timed events (e.g., reaction times, choice-decision times. Here, the traditional capabilities of computers are being exploited - namely, their accurate temporal sequencing, graphical performance, and, above all, their number crunching. As such, they have been powerful and essential tools for those involved in the more psychophysical or cognitive areas of psychology. Computer-based learning (CBL remains very much a preserve of these more formal domains. The arrival of hypermedia has opened the way for CBL to be exploited within the less formal domains of psychology; but the level of interactivity is usually very restricted, and the constrained presentational styles means that even this technological progression fails to meet the contextual richness needed in the teaching of much of the behavioural sciences. The advent of multimedia has for the first time provided the potential to explore, within the normal undergraduate learning environment, real behaviour using the observational techniques that form the basic methodology of the practising social psychologist.

    The Idaho National Laboratory (INL) computer-based procedure (CBP) research team is exploring how best to design a CBP system that will deliver the intended benefits of increased efficiency and improved human performance. It is important to note that no “off-the-shelf” technology exists for the type of CBP system that is investigated and developed by the INL researchers. As more technology is integrated into the procedure process the importance of an appropriate and methodological approach to the design of the procedure system increases. Technological advancements offer great opportunities for efficiency and safety gains, however if the system is not designed correctly there is a large risk of unintentionally introducing new opportunities for human errors. The INL research team is breaking new ground in the area of CBPs with the prototype they have developed. Current electronic procedure systems are most commonly electronic versions of the paper-based procedures with hyperlinks to other procedures, limited user input functionality, and the ability to mark steps completed. These systems do not fully exploit the advantages digital technology. It is a part of the INL researchers’ role to develop and validate new CBP technologies that greatly increase the benefits of a CBP system to the nuclear industry.

    Beside the performance, the safety level according to the actual standards is a compulsory condition for distribution grids’ operation. Some of the measures leading to improvement of the overhead lines reliability ask for installations’ modernization. The constraints imposed to the new lines components refer to the technical aspects as thermal stress or voltage drop, and look for economic efficiency, too. The mechanical sizing of the overhead lines is after all an optimization problem. More precisely, the task in designing of the overhead line profile is to size poles, cross-arms and stays and locate poles along a line route so that the total costs of the line's structure to be minimized and the technical and safety constraints to be fulfilled.The authors present in this paper an application for the Computer-Based Mechanical Design of the Overhead Lines and the features of the corresponding Visual Basic program, adjusted to the distribution lines. The constraints of the optimization problem are adjusted to the existing weather and loading conditions of Romania. The outputs of the software application for mechanical design of overhead lines are: the list of components chosen for the line: poles, cross-arms, stays; the list of conductor tension and forces for each pole, cross-arm and stay for different weather conditions; the line profile drawings.The main features of the mechanical overhead lines design software are interactivity, local optimization function and high-level user-interface

  9. Learning styles: individualizing computer-based learning environments

    1995-12-01

    Full Text Available While the need to adapt teaching to the needs of a student is generally acknowledged (see Corno and Snow, 1986, for a wide review of the literature, little is known about the impact of individual learner-differences on the quality of learning attained within computer-based learning environments (CBLEs. What evidence there is appears to support the notion that individual differences have implications for the degree of success or failure experienced by students (Ford and Ford, 1992 and by trainee end-users of software packages (Bostrom et al, 1990. The problem is to identify the way in which specific individual characteristics of a student interact with particular features of a CBLE, and how the interaction affects the quality of the resultant learning. Teaching in a CBLE is likely to require a subset of teaching strategies different from that subset appropriate to more traditional environments, and the use of a machine may elicit different behaviours from those normally arising in a classroom context.

  10. A Spread Willingness Computing-Based Information Dissemination Model

    2014-01-01

    Full Text Available This paper constructs a kind of spread willingness computing based on information dissemination model for social network. The model takes into account the impact of node degree and dissemination mechanism, combined with the complex network theory and dynamics of infectious diseases, and further establishes the dynamical evolution equations. Equations characterize the evolutionary relationship between different types of nodes with time. The spread willingness computing contains three factors which have impact on user’s spread behavior: strength of the relationship between the nodes, views identity, and frequency of contact. Simulation results show that different degrees of nodes show the same trend in the network, and even if the degree of node is very small, there is likelihood of a large area of information dissemination. The weaker the relationship between nodes, the higher probability of views selection and the higher the frequency of contact with information so that information spreads rapidly and leads to a wide range of dissemination. As the dissemination probability and immune probability change, the speed of information dissemination is also changing accordingly. The studies meet social networking features and can help to master the behavior of users and understand and analyze characteristics of information dissemination in social network.

  11. Computer Based Porosity Design by Multi Phase Topology Optimization

    Burblies, Andreas; Busse, Matthias

    2008-02-01

    A numerical simulation technique called Multi Phase Topology Optimization (MPTO) based on finite element method has been developed and refined by Fraunhofer IFAM during the last five years. MPTO is able to determine the optimum distribution of two or more different materials in components under thermal and mechanical loads. The objective of optimization is to minimize the component's elastic energy. Conventional topology optimization methods which simulate adaptive bone mineralization have got the disadvantage that there is a continuous change of mass by growth processes. MPTO keeps all initial material concentrations and uses methods adapted from molecular dynamics to find energy minimum. Applying MPTO to mechanically loaded components with a high number of different material densities, the optimization results show graded and sometimes anisotropic porosity distributions which are very similar to natural bone structures. Now it is possible to design the macro- and microstructure of a mechanical component in one step. Computer based porosity design structures can be manufactured by new Rapid Prototyping technologies. Fraunhofer IFAM has applied successfully 3D-Printing and Selective Laser Sintering methods in order to produce very stiff light weight components with graded porosities calculated by MPTO.

    2013-01-01

    In The Republic, Plato criticized poetry and poets, which caused the quarrel about poetry and philosophy in the history of western thoughts. The death of Socrates awaked Plato to that the politicians educat-ed by ancient Athens education, which was characterized by poetry controlling the government in Athens, re-jected truly advantageous proposals for Athens City States and caused harm to people of true wisdom. Poetry is the destruction of soul and national ruling. The quarrel about poetry and philosophy is actually the quarrel about political system and life style. Poetry which represents common people�s daily life is the patriarchal clan life that most people in city state live, and is closely identified with the political community. Philosophy represents a new life that a few people live to pursue wisdom, and it would inevitably clash with the polis political commu-nity.%  古希腊哲人柏拉图在其《理想国》中批判诗和诗人,引发了西方思想史上的“诗与哲学之争”。苏格拉底之死使柏拉图认识到,被以诗为主要内容的雅典教育培养出的政客把持着雅典政府,拒绝对城邦真正有利的提议,并对真正有智慧的人实施了伤害。诗是对灵魂与国家统治的败坏。诗与哲学之争实质上是政治制度和生活方式之争。诗代表了普通民众的日常生活,是城邦中多数人过的宗法生活,与城邦政治共同体密不可分;哲学则代表了一种新兴的生活,是少数人过的追求智慧的生活,与城邦政治共同体必然发生冲突。

    Zhang, Baohui

    Modeling has been promoted by major policy organizations as important for science learning. The purpose of this dissertation is to describe and explore middle school science students' computer-based modeling practices and their changes over time using a scaffolded modeling program. Following a "design-based research" approach, this study was conducted at an independent school. Seventh graders from three classes taught by two experienced teachers participated. Two pairs of target students were chosen from each class for observation. Students created computer-based models after their investigations in a water quality unit and a decomposition unit. The initial modeling cycle for water quality lasted for four days in the fall season, the second cycle for water quality lasted three days in the winter season, and the third cycle for decomposition lasted two days in the spring season. The major data source is video that captured student pairs' computer screen activities and their conversations. Supplementary data include classroom videos of those modeling cycles, replicated students' final models, and models in production. The data were analyzed in terms of the efficiency, meaningfulness, and purposefulness of students' modeling practices. Students' understanding of content, models and modeling, metacognition, and collaboration and their changes were analyzed as secondary learning outcomes. This dissertation shows that with appropriate scaffolding from the modeling program and the teachers, students performed a variety of modeling practices that are valued by science educators, such as planning, analyzing, synthesizing, evaluating, and publicizing. In general, student modeling practices became more efficient, meaningful, and purposeful over time. During their modeling practices, students also made use of and improved content knowledge, understanding of models and modeling, metacognition, and collaboration. Suggestions for improving the modeling program and the learning

    Wallen, Erik S; Mulloy, Karen B

    2006-01-01

    Computer-based safety training is becoming more common and is being delivered to an increasingly aging workforce. Aging results in a number of changes that make it more difficult to learn from certain types of computer-based training. Instructional designs derived from cognitive learning theories may overcome some of these difficulties. Three versions of computer-based respiratory safety training were shown to older and younger workers who then took a high and a low level learning test. Younger workers did better overall. Both older and younger workers did best with the version containing text with pictures and audio narration. Computer-based training with pictures and audio narration may be beneficial for workers over 45 years of age. Computer-based safety training has advantages but workers of different ages may benefit differently. Computer-based safety programs should be designed and selected based on their ability to effectively train older as well as younger learners.

    1995-01-01

    For Socrates, as he appears in Plato's dialogues, the process of discussion is essential for preparing human beings to lead a moral life. Only through discussion, Socrates maintains, can we be led to an understanding of such concepts as wisdom, courage and justice. The author of this article believes that the Socratic notion of the moral value of discussion is still valid. In support of this view, he examines two recent works: Dialogues on Moral Education by John Wilson and Barbara Cowell, and Moral Education, Secular and Religious by John L. Elias. Finally, the author suggests how the Socratic concept of dialogue might be used in moral education today.

    Nearly all activities that involve human interaction with nuclear power plant systems are guided by procedures, instructions, or checklists. Paper-based procedures (PBPs) currently used by most utilities have a demonstrated history of ensuring safety; however, improving procedure use could yield significant savings in increased efficiency, as well as improved safety through human performance gains. The nuclear industry is constantly trying to find ways to decrease human error rates, especially human error rates associated with procedure use. As a step toward the goal of improving field workers’ procedure use and adherence and hence improve human performance and overall system reliability, the U.S. Department of Energy Light Water Reactor Sustainability (LWRS) Program researchers, together with the nuclear industry, have been investigating the possibility and feasibility of replacing current paper-based procedures with computer-based procedures (CBPs). PBPs have ensured safe operation of plants for decades, but limitations in paper-based systems do not allow them to reach the full potential for procedures to prevent human errors. The environment in a nuclear power plant is constantly changing, depending on current plant status and operating mode. PBPs, which are static by nature, are being applied to a constantly changing context. This constraint often results in PBPs that are written in a manner that is intended to cover many potential operating scenarios. Hence, the procedure layout forces the operator to search through a large amount of irrelevant information to locate the pieces of information relevant for the task and situation at hand, which has potential consequences of taking up valuable time when operators must be responding to the situation, and potentially leading operators down an incorrect response path. Other challenges related to use of PBPs are management of multiple procedures, place-keeping, finding the correct procedure for a task, and relying

    This research effort is a part of the Light-Water Reactor Sustainability (LWRS) Program, which is a research and development (R&D) program sponsored by Department of Energy (DOE), performed in close collaboration with industry R&D programs, to provide the technical foundations for licensing and managing the long-term, safe, and economical operation of current nuclear power plants. The LWRS program serves to help the U.S. nuclear industry adopt new technologies and engineering solutions that facilitate the continued safe operation of the plants and extension of the current operating licenses. The introduction of advanced technology in existing nuclear power plants may help to manage the effects of aging systems, structures, and components. In addition, the incorporation of advanced technology in the existing LWR fleet may entice the future workforce, who will be familiar with advanced technology, to work for these utilities rather than more newly built nuclear power plants. Advantages are being sought by developing and deploying technologies that will increase safety and efficiency. One significant opportunity for existing plants to increase efficiency is to phase out the paper-based procedures (PBPs) currently used at most nuclear power plants and replace them, where feasible, with computer-based procedures (CBPs). PBPs have ensured safe operation of plants for decades, but limitations in paper-based systems do not allow them to reach the full potential for procedures to prevent human errors. The environment in a nuclear power plant is constantly changing depending on current plant status and operating mode.

    通过对柏拉图的《理想国》和莫尔的《乌托邦》的文本分析,我们发现他们的乌托邦思想中潜藏着共和主义叙事,实质上柏拉图和莫尔都希图建构一种共和主义乌托邦,由此也可以说乌托邦思想与共和主义之间原本就存在着一种共生的却被遗忘的历史关系,因而我们试图恢复以柏拉图和莫尔为代表的乌托邦思想家在共和主义政治光谱中的理论地位也并非一种主观冲动。%Through making a text analysis of Plato's Republic and Moore's Utopia,we find that a republican narrative has been hidden in their Utopian thought.Essencially,Plato and Moore both hoped to construct a republican utopia.It also can be said that there is a symbiotic and forgotten historical relation between the utopian thought and republicanism.So it is not a subjective impulse that we try to give the theoretical status in the republican political spectrum back to the utopian thinkers whose representatives are Plato and Moore.

  4. The great Lisbon earthquake and tsunami of 1755: lessons from the recent Sumatra earthquakes and possible link to Plato's Atlantis

    Science.gov (United States)

    Gutscher, M.-A.

    2006-05-01

    Great earthquakes and tsunami can have a tremendous societal impact. The Lisbon earthquake and tsunami of 1755 caused tens of thousands of deaths in Portugal, Spain and NW Morocco. Felt as far as Hamburg and the Azores islands, its magnitude is estimated to be 8.5 9. However, because of the complex tectonics in Southern Iberia, the fault that produced the earthquake has not yet been clearly identified. Recently acquired data from the Gulf of Cadiz area (tomography, seismic profiles, high-resolution bathymetry, sampled active mud volcanoes) provide strong evidence for an active east dipping subduction zone beneath Gibraltar. Eleven out of 12 of the strongest earthquakes (M>8.5) of the past 100 years occurred along subduction zone megathrusts (including the December 2004 and March 2005 Sumatra earthquakes). Thus, it appears likely that the 1755 earthquake and tsunami were generated in a similar fashion, along the shallow east-dipping subduction fault plane. This implies that the Cadiz subduction zone is locked (like the Cascadia and Nankai/Japan subduction zones), with great earthquakes occurring over long return periods. Indeed, the regional paleoseismic record (contained in deep-water turbidites and shallow lagoon deposits) suggests great earthquakes off South West Iberia every 1500 2000 years. Tsunami deposits indicate an earlier great earthquake struck SW Iberia around 200 BC, as noted by Roman records from Cadiz. A written record of even older events may also exist. According to Plato's dialogues The Critias and The Timaeus, Atlantis was destroyed by ‘strong earthquakes and floods … in a single day and night’ at a date given as 11,600 BP. A 1 m thick turbidite deposit, containing coarse grained sediments from underwater avalanches, has been dated at 12,000 BP and may correspond to the destructive earthquake and tsunami described by Plato. The effects on a paleo-island (Spartel) in the straits of Gibraltar would have been devastating, if inhabited, and may

  1. Implementing Computer-Based Procedures: Thinking Outside the Paper Margins

    Energy Technology Data Exchange (ETDEWEB)

    Oxstrand, Johanna; Bly, Aaron

    2017-06-01

    In the past year there has been increased interest from the nuclear industry in adopting the use of electronic work packages and computer-based procedures (CBPs) in the field. The goal is to incorporate the use of technology in order to meet the Nuclear Promise requirements of reducing costs and improve efficiency and decrease human error rates of plant operations. Researchers, together with the nuclear industry, have been investigating the benefits an electronic work package system and specifically CBPs would have over current paper-based procedure practices. There are several classifications of CBPs ranging from a straight copy of the paper-based procedure in PDF format to a more intelligent dynamic CBP. A CBP system offers a vast variety of improvements, such as context driven job aids, integrated human performance tools (e.g., placekeeping and correct component verification), and dynamic step presentation. The latter means that the CBP system could only display relevant steps based on operating mode, plant status, and the task at hand. The improvements can lead to reduction of the worker’s workload and human error by allowing the work to focus on the task at hand more. A team of human factors researchers at the Idaho National Laboratory studied and developed design concepts for CBPs for field workers between 2012 and 2016. The focus of the research was to present information in a procedure in a manner that leveraged the dynamic and computational capabilities of a handheld device allowing the worker to focus more on the task at hand than on the administrative processes currently applied when conducting work in the plant. As a part of the research the team identified type of work, instructions, and scenarios where the transition to a dynamic CBP system might not be as beneficial as it would for other types of work in the plant. In most cases the decision to use a dynamic CBP system and utilize the dynamic capabilities gained will be beneficial to the worker

    The computer-based teaching module (CBTM), which has recently gained prominence in medical education, is a teaching format in which a multimedia program serves as a single source for knowledge acquisition rather than playing an adjunctive role as it does in computer-assisted learning (CAL). Despite empirical validation in the past decade, there is limited research into the optimisation of CBTM design. This review aims to summarise research in classic and modern multimedia-specific learning theories applied to computer learning, and to collapse the findings into a set of design principles to guide the development of CBTMs. Scopus was searched for: (i) studies of classic cognitivism, constructivism and behaviourism theories (search terms: 'cognitive theory' OR 'constructivism theory' OR 'behaviourism theory' AND 'e-learning' OR 'web-based learning') and their sub-theories applied to computer learning, and (ii) recent studies of modern learning theories applied to computer learning (search terms: 'learning theory' AND 'e-learning' OR 'web-based learning') for articles published between 1990 and 2012. The first search identified 29 studies, dominated in topic by the cognitive load, elaboration and scaffolding theories. The second search identified 139 studies, with diverse topics in connectivism, discovery and technical scaffolding. Based on their relative representation in the literature, the applications of these theories were collapsed into a list of CBTM design principles. Ten principles were identified and categorised into three levels of design: the global level (managing objectives, framing, minimising technical load); the rhetoric level (optimising modality, making modality explicit, scaffolding, elaboration, spaced repeating), and the detail level (managing text, managing devices). This review examined the literature in the application of learning theories to CAL to develop a set of principles that guide CBTM design. Further research will enable educators to

    The objective of this study was to develop and validate a computer-based module for wrist arthroscopy to which a group of experts could consent. The need for such a module was assessed with members of the European Wrist Arthroscopy Society (EWAS). The computer-based module was developed through several rounds of consulting experts on the content. The module's learning enhancement was tested in a randomized controlled trial with 28 medical students who were assigned to the computer-based module group or lecture group. The design process led to a useful tool, which is supported by a panel of experts. Although the computer based module did not enhance learning, the participants did find the module more pleasant to use. Developing learning tools such as this computer-based module can improve the teaching of wrist arthroscopy skills.

  4. A dialogical exploration of the grey zone of health and illness: medical science, anthropology, and Plato on alcohol consumption.

    2009-01-01

    This paper takes a phenomenological hermeneutic orientation to explicate and explore the notion of the grey zone of health and illness and seeks to develop the concept through an examination of the case of alcohol consumption. The grey zone is an interpretive area referring to the irremediable zone of ambiguity that haunts even the most apparently resolute discourse. This idea points to an ontological indeterminacy, in the face of which decisions have to be made with regard to the health of a person (e.g., an alcoholic), a system (e.g., the health system), or a society. The fundamental character of this notion will be developed in relation to the discourse on health and the limitations of different disciplinary practices. The case of alcohol consumption will be used to tease out the grey zone embedded in the different kinds of knowledge made available through the disciplinary traditions of medical science, with its emphasis on somatic well-being, and anthropology, with its focus on communal well-being. This tension or grey zone embedded in different knowledge outcomes will be shown to have a discursive parallel with the dialogue between the Athenian, the Spartan, and the Cretan in Plato's Laws. Making use of the dialogical approach as described by Gadamer, the Athenian's particular resolution of the tension will be explored as a case study to demonstrate the necessarily particular analysis involved in a grey zone resolution.

  5. What is good sport: Plato's view Co je to dobrý sport: Platónův pohled

    Full Text Available One of Plato's most common questions found in his dialogues is "What is something?" By asking this question Plato usually brought his co-speakers to the recognition that in fact they do not have a full comprehension of what something is, although they have a partial comprehension of it. The awareness of one's incomplete cognition is the first step to be made on the philosophic way to truth. As in ancient times also today Plato asks us – the modern philosophers of sport – "What is sport?" or more precisely "What is good sport?" Probably the best of Plato's answers to this question can be found in the basic concepts of his philosophy regarding his hierarchical division of the state and human soul into three parts. Since sport is derived from human being also the goodness of sport can be divided into three stages. The lowest stage of sport corresponds to the first part of the soul – the appetite soul. On this stage sport is based on the gaining of material goods through prizes won at competitions. In the philosophic view, this is the lowest possible stage of goodness of sport. The second stage of sport corresponds to the second part of the soul – the emotional soul. Sport at this stage is based on the elementary ancient agon, which seeks fulfilment in the winning of honour and glory. The greatest and the most superior is the third part of the soul – the reasonable soul. According to this, also the sport corresponding to the third part of the soul is the best. For this kind of sport it is no longer necessary to compete with other contestants, since it can achieve it's fulfilment in perfect execution of movement or exercise, in which the perfect cooperation between reason (soul and body is attained. At this stage of sport it is the most important to compete and win over one's self, and this can be achieved by everyone, without regard to his/her physical abilities in comparison with others. In Plato's view, good sport is the sport directed

    The use of medical equipment is growing in healthcare, resulting in an increased need for resources to educate users in how to manage the various devices. Learning the practical operation of a device is one thing, but learning how to work with the device in the actual clinical context is more challenging. This paper presents a computer-based simulation prototype for learning medical technology in the context of critical care. Properties from simulation and computer games have been adopted to create a visualization-based, interactive and contextually bound tool for learning. A participatory design process, including three researchers and three practitioners from a clinic for infectious diseases, was adopted to adjust the form and content of the prototype to the needs of the clinical practice and to create a situated learning experience. An evaluation with 18 practitioners showed that practitioners were positive to this type of tool for learning and that it served as a good platform for eliciting and sharing knowledge. Our conclusion is that this type of tools can be a complement to traditional learning resources to situate the learning in a context without requiring advanced technology or being resource-demanding.

    Clinical reasoning is a core competence of doctors. Therefore, the assessment of clinical reasoning of undergraduate students is an important part of medical education. Three medical universities in the Netherlands wish to develop a shared question database in order to assess clinical reasoning of undergraduate students in Computer-Based Assessments (CBA). To determine suitable question types for this purpose a literature study was carried out. Search of ERIC and PubMed and subsequent cross referencing yielded 30 articles which met the inclusion criteria of a focus on question types suitable to assess clinical reasoning of medical students and providing recommendations for their use. Script Concordance Tests, Extended Matching Questions, Comprehensive Integrative Puzzles, Modified Essay Questions/Short Answer Questions, Long Menu Questions, Multiple Choice Questions, Multiple True/False Questions and Virtual Patients meet the above-mentioned criteria, but for different reasons not all types can be used easily in CBA. A combination of Comprehensive Integrative Puzzles and Extended Matching Questions seems to assess most aspects of clinical reasoning and these question types can be adapted for use in CBA. Regardless of the question type chosen, patient vignettes should be used as a standard stimulus format to assess clinical reasoning. Further research is necessary to ensure that the combination of these question types produces valid assessments and reliable test results.

    Computerized therapy approaches may expand the reach of evidence-based treatment; however, it is unclear how to integrate these therapies into community-based treatment. We conducted a two-phase pilot study to explore (a) whether clients' use of the Therapeutic Education System (TES), a Web-based community reinforcement approach (CRA) learning program, would benefit them in the absence of counselor support and (b) whether counselors and clients would use the TES in the absence of tangible research-based reinforcement. In Phase 1, clients in the TES condition (n = 14) demonstrated large improvements in knowledge, F(1, 20) = 8.90, p = .007, d = 1.05, and were significantly more likely to select CRA style coping responses, F (1, 20) = 11.95, p = .002, d = 1.16, relative to the treatment-as-usual group (n = 14). We also detected small, nonsignificant, between-group effects indicating TES decreased cocaine use during treatment. In Phase 2, counselors referred only around 10% of their caseload to the TES, and the modal number of completed modules in the absence of tangible reinforcement was three. Computer-based therapy approaches are viable in community-based treatment but must be integrated with incentive systems to ensure engagement. Copyright (c) 2010 Elsevier Inc. All rights reserved.

    The literature on intervention programs to improve arithmetical abilities is fragmentary and few studies have examined training on the symbolic representation of numbers (i.e. Arabic digits). In the present research, three groups of 3rd- and 5th-grade schoolchildren were given training on mental additions: 76 were assigned to a computer-based strategic training (ST) group, 73 to a process-based training (PBT) group, and 71 to a passive control (PC) group. Before and after the training, the children were given a criterion task involving complex addition problems, a nearest transfer task on complex subtraction problems, two near transfer tasks on math fluency, and a far transfer task on numerical reasoning. Our results showed developmental differences: 3rd-graders benefited more from the ST, with transfer effects on subtraction problems and math fluency, while 5th-graders benefited more from the PBT, improving their response times in the criterion task. Developmental, clinical and educational implications of these findings are discussed.

  10. Effects of people knowledge on science learning in a computer-based learning environment

    A weakness inherent in science education has been, and continues to be, its emphasis principally on the teaching of scientific knowledge, i.e. knowledge of the object (or the observed). Little attention has been directed to the teaching of people knowledge about scientists, i.e. knowledge of the subject (or the observer), who generates scientific knowledge. This study explored the possible effects of people knowledge on science learning. Participants in the study were 323 tenth graders from nine classes in a public school in Taipei, Taiwan. They were randomly assigned to three groups to self-study science in a computer-based learning environment. The control group was instructed to study various scientific laws discovered by three scientists in three science lessons. The other two groups were instructed to study the same science lessons after studying one of two kinds of people knowledge about the three scientists: achievement-oriented people knowledge (APK) and process-oriented people knowledge (PPK). APK profiles scientists' scientific achievements, and PPK describes scientists' struggles before making the scientific discoveries. The main findings were: Firstly, it was found from problem-solving tests that all three groups performed equally well in applying what they learned from the lessons to solve textbook problems. However, in applying what they learned to interpret the relationships between scientific laws, only the PPK group performed better. Secondly, regarding learning interest, among the students who showed high personal interest in science, the APK group tended to consider the lessons as less interesting than the control group. Among the students who demonstrated low personal interest in science, the PPK group tended to consider the science lessons as more interesting than the control group. Thirdly, in describing their image of the three scientists, the APK group tended to emphasize the abilities and successes of the scientists, whereas the PPK group

    Full Text Available Foreign language skill is one of the components highly demanded by employers in the sphere of economics, business and finance. Adequate level of foreign language proficiency can be achieved with a thoroughly selected type of assessment which shows the progresses made by graduates and help to adapt teaching techniques and learning standards to changing requirements. Computer based testing and oral type of assessment are common ways to estimate graduates’ foreign language proficiency level. The aim of the present study is to determine the type of assessment which best suits the purpose of higher educational establishment and can be used within graduates’ possibilities. Authors came to the conclusion that both CBT and oral type of assessment should constitute the framework of the assessment procedure and be used in their combination because in that way they respond to the needs of higher educational establishment and comply with graduates’ differences respectively.

    Full Text Available Laboratory experimentation in engineering is an essential part of the three main components in an engineer's formation. The theoretical constructs and models are imparted in lectures and tutorials. Workshop hands-on activity allows the student to acquire an understanding of the interaction of design and manufacture, and the constraints both impose. Characteristics of plant are investigated through experiment, and this aids the learner's understanding of the limitation of models in predicting performance. The learner also gains an appreciation of the nature of errors and of the construction of plant. But while the oil industry has brought prosperity to the North- East, it has also brought unique educational demands: the working arrangements place severe restrictions on part-time student attendance. Technicians work a block of two to four weeks offshore, followed by a similar period of leave. Different companies have different arrangements, and shift-change days.

    Full Text Available Political rhetoric about knowledge economies and learning societies really ought to be an educationalist's dream. Add to that the revolutionary power of electronic media, and an insatiable hunger for archaeology among the public, archaeology teaching should be well placed to flourish. In England, the Department for Culture Media and Sport has just closed its call for interest in the multi-million pound Culture Online programme. The New Opportunities Fund has already spent fifty million pounds on digitisation alone, while the Heritage Lottery Fund is encouraging heritage agencies to distribute their data sets online. The JISC continues to expand its information environment, investing most recently in virtual learning environments. In Europe, the 6th Framework promises a single European Research Area, and grid technologies allow high quantities of data to empower an information society - supported by the millions of euros already invested in 'e-content'. All of these programmes, and many many more, provide openings for archaeologists to invest in training, teaching and learning. How can archaeology, in particular staff and students in our educational establishments, take best advantage of this information-rich, digitally-empowered learning society?

  15. The influence of Plato, Aristotle, and the ancient Polis on a programme for congenital cardiac surgery: the virtuous partnership.

    The problems that exist in maintaining a partnership in paediatric cardiac surgery are considerable. They relate to fairness in allocation of time for leisure, the apportioning of cases between the partners, internal competition between them, financial considerations, and promotion of the ego. In this review, we discuss our own experiences in maintaining a partnership over a period of more than 18 years, relating such a "virtuous partnership" to the writings of Plato and Aristotle, and setting it against the tenets of the ancient Greek polis. The polis, or city state, came to prominence in ancient Greece during the golden age of Pericles, this period seeing the initial evolution of Western philosophy, as well as numerous other scientific, artistic and architectural advances. The concept of the polis was to create a natural association with its citizens that nurtured all that is best in people, at the same time defining their character. In this respect, according to Plato, the person and the polis are mirror images. Aristotle then expanded this notion to incorporate the various forms of friendship, which he pointed out last only as long as the interrelated pleasure survives. Using these principles as the point of departure, we argue that cardiac surgeons should respect moral virtue in each other. Extending this process means that we should also respect, and celebrate, our relationships with affiliated physicians, nurses, perfusionists, administrators, and all concerned in the care of children with congenitally malformed hearts. In this way, we create a virtuous partnership for congenital cardiac surgery that promotes all that was good, as engendered in the ancient Greek polis. As we extend these observations to the modern world, we discuss some of the features that have permitted us to work so well together. One of the most important is a summoning and unwritten tenet that greets us as we enter the operating room, namely "check your ego at the door". The operative

    2001-11-01

    Full Text Available This paper explores the issue of whether computer-based support tools can enhance the use of 'soft' systems methodologies as applied to real-world problem situations. Although work has been carried out by a number of researchers in applying computer-based technology to concepts and methodologies relating to 'soft' systems thinking such as Soft Systems Methodology (SSM, such attempts appear to be still in their infancy and have not been applied widely to real-world problem situations. This paper will highlight some of the problems that may be encountered in attempting to develop computer-based support tools for 'soft' systems methodologies. Particular attention will be paid to an attempt by the author to develop a computer-based support tool for a particular 'soft' systems method of inquiry known as the Appreciative Inquiry Method that is based upon Vickers' notion of 'appreciation' (Vickers, 196S and Checkland's SSM (Checkland, 1981. The final part of the paper will explore some of the lessons learnt from developing and applying the computer-based support tool to a real world problem situation, as well as considering the feasibility of developing computer-based support tools for 'soft' systems methodologies. This paper will put forward the point that a mixture of manual and computer-based tools should be employed to allow a methodology to be used in an unconstrained manner, but the benefits provided by computer-based technology should be utilised in supporting and enhancing the more mundane and structured tasks.

    Nursing educators must ensure that nursing students acquire the necessary competencies; finding the most purposeful teaching methods and encouraging learning through meaningful learning opportunities is necessary to meet this goal. We investigated student learning in a simulated nursing practice using videography. The purpose of this paper is to examine how two different teaching methods presented students' meaningful learning in a simulated nursing experience. The 6-hour study was divided into three parts: part I, general information; part II, training; and part III, simulated nursing practice. Part II was delivered by two different methods: a computer-based simulation and a lecture. The study was carried out in the simulated nursing practice in two universities of applied sciences, in Northern Finland. The participants in parts II and I were 40 first year nursing students; 12 student volunteers continued to part III. Qualitative analysis method was used. The data were collected using video recordings and analyzed by videography. The students who used a computer-based simulation program were more likely to report meaningful learning themes than those who were first exposed to lecture method. Educators should be encouraged to use computer-based simulation teaching in conjunction with other teaching methods to ensure that nursing students are able to receive the greatest educational benefits.

    Laboratory exercises are intended to illustrate concepts and add an active learning component to courses. Since 1980s, there has been a decline in animal laboratories in medical physiology courses. Other cost-effective non-aninmal alternatives are being sought. The present study was designed to find out the students' opinion regarding the animal versus computer lab and whether innovative teaching methodologies helped students achieve their goals. Opinions of 481 female in medical students of 2nd and 3rd year MBBS were included in the study. A questionnaire based on animal/computer based experiments and new teaching methodologies in physiology was voluntarily filled in by the students. Majority of students immensely benefited from both the animal lab and other teaching methodologies. Although computer based learning is considered effective in helping students acquire basic concepts, there is evidence that some students acquire a more thorough understanding of the material through more advanced and challenging experience of an animal laboratory. The fact that such labs as well various teaching methods offer distinct educational advantages should be taken into account when courses are designed.

    Developing scientific reasoning skills is a common learning objective for general-education science courses. However, effective assessments for such skills typically involve open-ended questions or tasks, which must be hand-scored and may not be usable online. Using computer-based learning environments, reasoning can be assessed automatically by analyzing student actions within the learning environment. We describe such an assessment under development and present pilot results. In our content-neutral instrument, students solve a problem by collecting and interpreting data in a logical, systematic manner. We then infer reasoning skill automatically based on student actions. Specifically, students investigate why Earth has seasons, a scientifically simple but commonly misunderstood topic. Students are given three possible explanations and asked to select a set of locations on a world map from which to collect temperature data. They then explain how the data support or refute each explanation. The best approaches will use locations in both the Northern and Southern hemispheres to argue that the contrasting seasonality of the hemispheres supports only the correct explanation. We administered a pilot version to students at the beginning of an online, introductory science course (n = 223) as an optional extra credit exercise. We were able to categorize students' data collection decisions as more and less logically sound. Students who choose the most logical measurement locations earned higher course grades, but not significantly higher. This result is encouraging, but not definitive. In the future, we will clarify our results in two ways. First, we plan to incorporate more open-ended interactions into the assessment to improve the resolving power of this tool. Second, to avoid relying on course grades, we will independently measure reasoning skill with one of the existing hand-scored assessments (e.g., Critical Thinking Assessment Test) to cross-validate our new

    The Detroit Medical Center nursing documentation system requires all staff nurses to complete the Braden Scale for Predicting Pressure Sore Risk on an Acute Care Flow Record or Critical Care Flow Sheet on every patient, every day. An audit of these records raised concern as to whether staff nurses accurately used the Braden Scale to calculate pressure sore risk. Advanced Practice and ET Nurses noted that staff nurses were rating patients at lower levels of pressure sore risk than was warranted by the patient condition. In response, a computer-based learning module with case study examples was developed and tested to teach nursing staff to accurately evaluate pressure ulcer risk by using the Braden Scale and its subscales and to identify preventive interventions based on the patient's Braden subscale scores. Following revisions of those case study example narratives that were found to be problematic, the learning/assessment module was instituted in 2002. More than 2,500 nurses at the facility were tested regarding their knowledge of pressure ulcer risk assessment and prevention using this program. On average, nurses correctly rated the Braden Scale level of risk 75.6% of the time. The percentage of correct responses was highest for very high (92%) and very low (78%) levels of risk. This finding is consistent with the observation that most nosocomial pressure ulcers in this facility occur in patients who are rated in the "mild risk" level on the Braden scale. Subscales with the lowest percentage of correct answers were moisture and sensory perception. Correct clinical identification of a Stage I pressure ulcer as it was described in writing occurred only 53% of the time. These results indicate that training and practice are needed to use an assessment scale accurately. The Detroit Medical Center plans to include the Braden Scale in annual nursing education and competency testing.

    Recent recommendations urge increased depression screening in pregnant and postpartum women, potentially increasing demand for treatment. Computer-based psychotherapy treatments may address some of perinatal women's unique mental health treatment needs and barriers. We conducted a quantitative survey of pregnant women (≥12 weeks of gestation) on preferences regarding computer-based therapies compared with traditional therapies (psychotherapy and medication). Nonpregnant women and men served as comparison groups. Participants were provided descriptions of three computer-based therapies: video telehealth therapy (VTT), computer-assisted therapy (CAT), and self-guided online therapy (SGO). Participants were asked to select all options that they would consider for treatment as well as first choice preference. The Patient Health Questionnaire-9 (PHQ-9) assessed current depressive symptomatology, and the Mini International Neuropsychiatric Interview (MINI) assessed psychiatric history. Participants included pregnant females (n = 111), nonpregnant females (n = 147), and males (n = 54). Among pregnant women, 77.5% (n = 86) indicated that they would consider some form of computer-based therapy for mental health treatment during pregnancy; VTT was the most commonly considered, followed by CAT and SGO. When asked to select their preferred intervention, traditional talk therapy was the first choice among all three groups, controlling for treatment history and PHQ-9 score. About one-third of pregnant women chose some form of computer-based therapy as their top choice. While computer-based therapies were acceptable to most pregnant women in this sample, traditional talk therapy was the preferred option. Future research should consider how to tailor computer-based therapies to the unique needs of perinatal women.

    Ticagrelor, a novel, reversible, and oral P2Y12 receptor antagonist, was claimed to reduce all-cause mortality compared to clopidogrel in the PLATO trial. We sought to ascertain vital status follow-up for clopidogrel and ticagrelor to determine if any discrepancy existed by reviewing data from the FDA Complete Response Review. The FDA Complete Response Review indicated misrepresentation of vital status follow-up by the sponsor's presenter at the Cardiovascular and Renal Drugs Advisory Committee. Instead of five patients with missing vital status follow-up, the FDA primary efficacy reviewer indicated that there was a minimum of 106 patients. Additionally and more concerning was the fact that significantly more patients on ticagrelor (3.1%, n = 289 patients) had incomplete vital status follow-up versus clopidogrel (2.6%, n = 242 patients, p = 0.04 for the difference). The Advisory Committee that voted in favor to approve ticagrelor was given misrepresented data, which may have affected the approval of ticagrelor. The fact that significantly more patients on ticagrelor had incomplete vital status follow-up versus clopidogrel challenges the claimed mortality benefit of ticagrelor and the approval of the PLATO trial. © 2013 Elsevier Ireland Ltd.

    Full Text Available Many teaching centers have now adopted objective structured clinical examination (OSCE as an assessment method for undergraduate dermatology courses. A modification of the standard OSCE in dermatology is computer based or electronic OSCE (eOSCE. We attempted to validate the use of a computer-based OSCE in dermatology in a group of fifth year medical students. The scores of the students in the computer-based OSCE showed a strong positive correlation with the scores on the clinical presentation (Pearson′s co-efficient - 0.923, P value <0.000, significant at the 0.01 level and a good correlation with overall scores of the student (Pearson′s co-efficient - 0.728, P value <0.000, significant at the 0.01 level, indicating that this is a reliable method for assessment in dermatology. Generally, the students′ feedback regarding the methods was positive.

    2013-01-01

    Background Healthcare professionals develop workarounds rather than using electronic health record (EHR) systems. Understanding the reasons for workarounds is important to facilitate user-centered design and alignment between work context and available health information technology tools. Objective To examine both paper- and computer-based workarounds to the use of EHR systems in three benchmark institutions. Methods Qualitative data were collected in 11 primary care outpatient clinics across three healthcare institutions. Data collection methods included direct observation and opportunistic questions. In total, 120 clinic staff and providers and 118 patients were observed. All data were analyzed using previously developed workaround categories and examined for potential new categories. Additionally, workarounds were coded as either paper- or computer-based. Results Findings corresponded to 10 of 11 workaround categories identified in previous research. All 10 of these categories applied to paper-based workarounds; five categories also applied to computer-based workarounds. One new category, no correct path (eg, a desired option did not exist in the computer interface, precipitating a workaround), was identified for computer-based workarounds. The most consistent reasons for workarounds across the three institutions were efficiency, memory, and awareness. Conclusions Consistent workarounds across institutions suggest common challenges in outpatient clinical settings and failures to accommodate these challenges in EHR design. An examination of workarounds provides insight into how providers adapt to limiting EHR systems. Part of the design process for computer interfaces should include user-centered methods particular to providers and healthcare settings to ensure uptake and usability. PMID:23492593

    The importance of the design of human machine interfaces (HMIs) for human performance and safety has long been recognized in process industries. In case of nuclear power plants (NPPs), HMIs have significant implications for the safety of the NPPs since poor implementation of HMIs can impair the operators' information searching ability which is considered as one of the important aspects of human behavior. To support and increase the efficiency of the operators' information searching behavior, advanced HMIs based on computer technology are provided. Operators in advanced main control room (MCR) acquire information through video display units (VDUs), and large display panel (LDP) required for the operation of NPPs. These computer-based displays contain a very large quantity of information and present them in a variety of formats than conventional MCR. For example, these displays contain more elements such as abbreviations, labels, icons, symbols, coding, and highlighting than conventional ones. As computer-based displays contain more information, complexity of the elements becomes greater due to less distinctiveness of each element. A greater understanding is emerging about the effectiveness of designs of computer-based displays, including how distinctively display elements should be designed. And according to Gestalt theory, people tend to group similar elements based on attributes such as shape, color or pattern based on the principle of similarity. Therefore, it is necessary to consider not only human operator's perception but the number of element consisting of computer-based display

    2016-07-01

    We produced a "toy-model" of one Telescope Optical Unit of PLATO, the Medium sized mission selected by ESA to fly in 2024. This is a six lenses dioptric very wide field camera with a window in front to take care of radiation impact on the first lens whose optical glass cannot be replaced with a radiation hardened one. The main aim of this project is just to produce a "cool" model for display purposes, in which one can "explore" the details of the inside through some openings in the tube, in order to visually inspect some of the fine details of the opto-mechanics. While its didactic and advertising role is out of doubt, during its construction we realized that some interesting outcome can be of some relevance for the project itself and that some findings could be useful, in order to assess the ability of producing with the same technology some (of course of much more modest quality) optical systems. In this context, we immediately dropped the option of producing the lenses with opaque material painted with a color resembling a refractive material (like blue for instance) and decided to actually produce them with transparent plastic. Furthermore the surfaces are then finely polished in order to give them basic optical properties. Such an optical system has only very coarsely the converging properties of the original nominal design for a number of reasons: the refractive indexes are not the nominal ones, the quality of the surfaces and their nominal values are only roughly, within a few percent, the targeted one, and the way the surfaces are built up makes them prone to some diffraction effects. However, the bulk of the lens and the surface roughness will give a large magnification of the scattering effects that will be experienced, at a much lower level, on the actual flight model. We investigated through propagation of a laser beam and by digital camera the main stray light modes that this toymodel offers. In other words, the model amplifies, to a large extent, the

    Full Text Available Saee Deshpande, Jayashree Chahande Department of Prosthodontics, Vidya Shikshan Prasarak Mandal's (VPSM Dental College and Research Centre, Nagpur, Maharashtra, India Purpose: Successful prosthodontic rehabilitation involves making many interrelated clinical decisions which have an impact on each other. Self-directed computer-based training has been shown to be a very useful tool to develop synthetic and analytical problem-solving skills among students. Thus, a computer-based case study and treatment planning (CSTP software program was developed which would allow students to work through the process of comprehensive, multidisciplinary treatment planning for patients in a structured and logical manner. The present study was aimed at assessing the effect of this CSTP software on the clinical judgment of dental students while planning prosthodontic rehabilitation and to assess the students' perceptions about using the program for its intended use. Methods: A CSTP software program was developed and validated. The impact of this program on the clinical decision making skills of dental graduates was evaluated by real life patient encounters, using a modified and validated mini-CEX. Students' perceptions about the program were obtained by a pre-validated feedback questionnaire. Results: The faculty assessment scores of clinical judgment improved significantly after the use of this program. The majority of students felt it was an informative, useful, and innovative way of learning and they strongly felt that they had learnt the logical progression of planning, the insight into decision making, and the need for flexibility in treatment planning after using this program. Conclusion: CSTP software was well received by the students. There was significant improvement in students' clinical judgment after using this program. It should thus be envisaged fundamentally as an adjunct to conventional teaching techniques to improve students' decision making skills

    Rothman, Alan H.

    This study reports the results of research designed to examine the impact of computer-based science instruction on elementary school level students' science content achievement, their attitude about science learning, their level of critical thinking-inquiry skills, and their level of cognitive and English language development. The study compared these learning outcomes resulting from a computer-based approach compared to the learning outcomes from a traditional, textbook-based approach to science instruction. The computer-based approach was inherent in a curriculum titled The Voyage of the Mimi , published by The Bank Street College Project in Science and Mathematics (1984). The study sample included 209 fifth-grade students enrolled in three schools in a suburban school district. This sample was divided into three groups, each receiving one of the following instructional treatments: (a) Mixed-instruction primarily based on the use of a hardcopy textbook in conjunction with computer-based instructional materials as one component of the science course; (b) Non-Traditional, Technology-Based -instruction fully utilizing computer-based material; and (c) Traditional, Textbook-Based-instruction utilizing only the textbook as the basis for instruction. Pre-test, or pre-treatment, data related to each of the student learning outcomes was collected at the beginning of the school year and post-test data was collected at the end of the school year. Statistical analyses of pre-test data were used as a covariate to account for possible pre-existing differences with regard to the variables examined among the three student groups. This study concluded that non-traditional, computer-based instruction in science significantly improved students' attitudes toward science learning and their level of English language development. Non-significant, positive trends were found for the following student learning outcomes: overall science achievement and development of critical thinking

    Meurant, Robert C.

    Sorting of Korean English-as-a-Foreign-Language (EFL) university students by Second Language (L2) aptitude allocates students to classes of compatible ability level, and was here used to screen candidates for interview. Paper-and-pen versions of the Oxford Quick Placement Test were adapted to computer-based testing via online hosting using FSCreations ExamView. Problems with their online hosting site led to conversion to the popular computer-based learning management system Moodle, hosted on www.ninehub.com. 317 sophomores were tested online to encourage L2 digital literacy. Strategies for effective hybrid implementation of Learning Management Systems in L2 tertiary education include computer-based Internet-hosted L2 aptitude tests. These potentially provide a convenient measure of student progress in developing L2 fluency, and offer a more objective and relevant means of teacher- and course-assessment than student evaluations, which tend to confuse entertainment value and teacher popularity with academic credibility and pedagogical effectiveness.

    Computer-based audiometry allows for novel applications, including remote testing and automation, that may improve the accessibility and efficiency of hearing assessment in various clinical and occupational health settings. This study describes the validity of computer-based, diagnostic air and forehead bone conduction audiometry when compared wtih conventional industry standard audiometry in a sound booth environment. A sample of 30 subjects (19 to 77 years of age) was assessed with computer-based (KUDUwave 5000) and industry standard conventional audiometers (GSI 61) to compare air and bone conduction thresholds and test-retest reliability. Air conduction thresholds for the two audiometers corresponded within 5 dB or less in more than 90% of instances, with an average absolute difference of 3.5 dB (3.8 SD) and a 95% confidence interval of 2.6 to 4.5 dB. Bone conduction thresholds for the two audiometers corresponded within 10 dB or less in 92% of instances, with an average absolute difference of 4.9 dB (4.9 SD) and a 95% confidence interval of 3.6 to 6.1 dB. The average absolute test-retest threshold difference for bone conduction on the industry standard audiometer was 5.1 dB (5.3 SD) and for the computer-based audiometer 7.1 dB (6.4 SD). Computer-based audiometry provided air and bone conduction thresholds within the test-retest reliability limits of industry standard audiometry.

Many thinkers have posed questions to find out what to do to remedy the imperfections of these institutions. For Plato the recommended solution to this crisis was nothing other than education of the archon or the philosopher. This is based because of The Republic means government or constitution of the city. This must invest in training of these citizens to support their development and that of the nation. Today Human education entering the political career is not in vain, but rather essential to the national interest. Only Karl Popper considered the society of Plato a closed society because his education is moral inspiration in faith rather than reason. Also, imitate the education level of contemplative truth will mark an absence multicultural concert of globalization. If really community of women in Plato existed, there would be no survivor has given the proliferation of pandemic diseases. Without forgetting that of children.

    Meurant, Robert C.

    Second Language (L2) Digital Literacy is of emerging importance within English as a Foreign Language (EFL) in Korea, and will evolve to become regarded as the most critical component of overall L2 English Literacy. Computer-based Internet-hosted Learning Management Systems (LMS), such as the popular open-source Moodle, are rapidly being adopted worldwide for distance education, and are also being applied to blended (hybrid) education. In EFL Education, they have a special potential: by setting the LMS to force English to be used exclusively throughout a course website, the meta-language can be made the target L2 language. Of necessity, students develop the ability to use English to navigate the Internet, access and contribute to online resources, and engage in computer-mediated communication. Through such pragmatic engagement with English, students significantly develop their L2 Digital Literacy.

  16. The Validation of Computer-based Models in Engineering: Some Lessons from Computing Science

    Directory of Open Access Journals (Sweden)

    D. J. Murray-Smith

    2001-01-01

    Full Text Available Questions of the quality of computer-based models and the formal processes of model testing, involving internal verification and external validation, are usually given only passing attention in engineering reports and in technical publications. However, such models frequently provide a basis for analysis methods, design calculations or real-time decision-making in complex engineering systems. This paper reviews techniques used for external validation of computer-based models and contrasts the somewhat casual approach which is usually adopted in this field with the more formal approaches to software testing and documentation recommended for large software projects. Both activities require intimate knowledge of the intended application, a systematic approach and considerable expertise and ingenuity in the design of tests. It is concluded that engineering degree courses dealing with modelling techniques and computer simulation should put more emphasis on model limitations, testing and validation.

    Lisa D. Young

    2003-10-01

    Full Text Available Abstract. The design of computer-based learning environments has undergone a paradigm shift; moving students away from instruction that was considered to promote technical rationality grounded in objectivism, to the application of computers to create cognitive tools utilized in constructivist environments. The goal of the resulting computer-based learning environment design principles is to have students learn with technology, rather than from technology. This paper reviews the general constructivist theory that has guided the development of these environments, and offers suggestions for the adaptation of modest, generic guidelines, not mandated principles, that can be flexibly applied and allow for the expression of true constructivist ideals in online learning environments.

Computer-based case simulations (CCS have been used for teaching and assessment of clinical reasoning skills. However, previous studies examining the psychometric properties of CCS as an assessment tool have been controversial. Furthermore, studies reporting the integration of CCS into problem-based medical curricula have been limited. Methods: This study examined the psychometric properties of using CCS software (DxR Clinician for assessment of medical students (n=130 studying in a problem-based, integrated multisystem module (Unit IX during the academic year 2011–2012. Internal consistency reliability of CCS scores was calculated using Cronbach's alpha statistics. The relationships between students' scores in CCS components (clinical reasoning, diagnostic performance, and patient management and their scores in other examination tools at the end of the unit including multiple-choice questions, short-answer questions, objective structured clinical examination (OSCE, and real patient encounters were analyzed using stepwise hierarchical linear regression. Results: Internal consistency reliability of CCS scores was high (α=0.862. Inter-item correlations between students' scores in different CCS components and their scores in CCS and other test items were statistically significant. Regression analysis indicated that OSCE scores predicted 32.7% and 35.1% of the variance in clinical reasoning and patient management scores, respectively (P<0.01. Multiple-choice question scores, however, predicted only 15.4% of the variance in diagnostic performance scores (P<0.01, while
