  10. Effect of lecture instruction on student performance on qualitative questions

    Science.gov (United States)

    Heron, Paula R. L.

    2015-06-01

    The impact of lecture instruction on student conceptual understanding in physics has been the subject of research for several decades. Most studies have reported disappointingly small improvements in student performance on conceptual questions despite direct instruction on the relevant topics. These results have spurred a number of attempts to improve learning in physics courses through new curricula and instructional techniques. This paper contributes to the research base through a retrospective analysis of 20 randomly selected qualitative questions on topics in kinematics, dynamics, electrostatics, waves, and physical optics that have been given in introductory calculus-based physics at the University of Washington over a period of 15 years. In some classes, questions were administered after relevant lecture instruction had been completed; in others, it had yet to begin. Simple statistical tests indicate that the average performance of the "after lecture" classes was significantly better than that of the "before lecture" classes for 11 questions, significantly worse for two questions, and indistinguishable for the remaining seven. However, the classes had not been randomly assigned to be tested before or after lecture instruction. Multiple linear regression was therefore conducted with variables (such as class size) that could plausibly lead to systematic differences in performance and thus obscure (or artificially enhance) the effect of lecture instruction. The regression models support the results of the simple tests for all but four questions. In those cases, the effect of lecture instruction was reduced to a nonsignificant level, or increased to a significant, negative level when other variables were considered. Thus the results provide robust evidence that instruction in lecture can increase student ability to give correct answers to conceptual questions but does not necessarily do so; in some cases it can even lead to a decrease.

  11. Student performance on conceptual questions: Does instruction matter?

    Heron, Paula R. L.

    2013-01-01

    As part of the tutorial component of introductory calculus-based physics at the University of Washington, students take weekly pretests that consist of conceptual questions. Pretests are so named because they precede each tutorial, but they are frequently administered after lecture instruction. Many variables associated with class composition and prior instruction (if any) could, in principle, affect student performance on these questions. Nonetheless, the results are often found to be "essentially the same" in all classes. With data available from a large number of classes, it is possible to characterize the typical variation quantitatively. In this paper three questions for which we have accumulated thousands of responses, from dozens of classes representing different conditions with respect to the textbook in use, the amount of prior instruction, etc., serve as examples. For each question, we examine the variation in student performance across all classes. We also compare subsets categorized according to the amount of relevant prior instruction each class had received. A preliminary analysis suggests that the variation in performance is essentially random. No statistically significant difference is observed between results obtained before relevant instruction begins and after it has been completed. The results provide evidence that exposure to concepts in lecture and textbook is not sufficient to ensure an improvement in performance on questions that require qualitative reasoning.

  12. Learning and performance under alternative instructional manifestations of experimental practice

    Science.gov (United States)

    Ford, Michael J.

    Before we can understand how students learn "to do" science, we must make explicit our assumptions about what scientific practice is. This study compares the learning outcomes of two sixth-grade instructional units on experimentation, each based on a particular characterization of practice. In one unit, instruction focused on acquisition and application of the control of variables strategy (CVS; Chen & Klahr, 1999), which is consistent with a popular conception of science education, stemming from Piaget, as the mastery of logical forms. In the other unit, students designed experimental apparatus to answer a target question, and instruction emphasized practices of rendering and transforming the material world in ways that support scientific understanding. Students in both groups were assessed for CVS acquisition and subsequent experimental performance on a novel task, and group performances on these assessments different across instructional conditions. I will argue that student understandings of goals, norms of instructional expectation, and strategies explain these differences, in some cases by supporting performance and in other cases by hindering it. I will also argue that the results question the role typically attributed to logical method in learning to design experiments.

    1999-06-01

    One of the challenges for characterizing and modeling realistic multimedia applications is the lack of access to source codes. On-chip performance counters effectively resolve this problem by monitoring run-time behaviors at the instruction-level. This paper presents a novel technique of characterizing and modeling workloads at the instruction level for realistic multimedia applications using hardware performance counters. A variety of instruction counts are collected from some multimedia applications, such as RealPlayer, GSM Vocoder, MPEG encoder/decoder, and speech synthesizer. These instruction counts can be used to form a set of abstract characteristic parameters directly related to a processor`s architectural features. Based on microprocessor architectural constraints and these calculated abstract parameters, the architectural performance bottleneck for a specific application can be estimated. Meanwhile, the bottleneck estimation can provide suggestions about viable architectural/functional improvement for certain workloads. The biggest advantage of this new characterization technique is a better understanding of processor utilization efficiency and architectural bottleneck for each application. This technique also provides predictive insight of future architectural enhancements and their affect on current codes. In this paper the authors also attempt to model architectural effect on processor utilization without memory influence. They derive formulas for calculating CPI{sub 0}, CPI without memory effect, and they quantify utilization of architectural parameters. These equations are architecturally diagnostic and predictive in nature. Results provide promise in code characterization, and empirical/analytical modeling.

    2017-07-01

    Studies on prospective memory (PM) development in adolescents point to age-related increases through to adulthood. The goal of the present study was to examine whether instructing adolescents to engage in an episodic prospection of themselves executing future actions (i.e., future thinking) when forming an intention would improve their PM performance and reduce age-related differences. Further, we set out to explore whether future thinking instructions result in stronger memory traces and/or stronger cue-context associations by evaluating retrospective memory for the PM cues after task completion and monitoring costs during PM task processing. Adolescents and young adults were allocated to either the future thinking, repeated-encoding or standard condition. As expected, adolescents had fewer correct PM responses than young adults. Across age groups, PM performance in the standard condition was lower than in the other encoding conditions. Importantly, the results indicate a significant interaction of age by encoding condition. While adolescents benefited most from future thinking instructions, young adults performed best in the repeated-encoding condition. The results also indicate that the beneficial effects of future thinking may result from deeper intention-encoding through the simulation of future task performance.

  20. Instructional practices and science performance of 10 top-performing regions in PISA 2015

    Lau, Kwok-chi; Lam, Terence Yuk-ping

    2017-10-01

    This study analysed 10 top-performing regions in PISA 2015 on their science performances and instructional practices. The regions include Singapore, Japan, Estonia, Taipei, Finland, Macao, Canada, Hong Kong, China and Korea. The science performances of the 10 regions and their teaching practices are described and compared. The construct of enquiry-based instruction as developed in PISA 2015 is revised into two new constructs using factor analysis. Then, the relationships of the teaching practices with science performance are analysed using hierarchical linear modelling. Adaptive instruction, teacher-directed instruction and interactive application are found positively associated with performance in all regions, while investigation and perceived feedback are all negative. The regions except Japan and Korea tend to have a high frequency of teacher-directed instruction facilitated by more or less authoritative class discussion in class. A fair amount of practical work is done, but not many of them are investigations. The cultural influences on teaching practices are discussed on how an amalgam of didactic and constructivist pedagogy is created by the Western progressive educational philosophy meeting the Confucian culture. The reasons for investigation's negative association with performance are also explored.

    Research has established that competing head to head against a rival boosts motivation and performance. The present research investigated whether rivalry can affect performance over time and in contests without rivals. We examined the long-term effects of rivalry through archival analyses of postseason performance in multiple high-stakes sports contexts: National Collegiate Athletic Association (NCAA) Division I Men's Basketball and the major U.S. professional sports leagues: National Basketball Association (NBA), National Football League (NFL), Major League Baseball (MLB), and National Hockey League (NHL). Econometric analyses revealed that postseason performance of a focal team's rival in year N predicted that focal team's postseason performance in year N + 1. Follow-up analyses suggested that the performance boost was especially pronounced when one's rival won the previous tournament. These results establish that rivalry has a long shadow: A rival team's success exerts such a powerful motivational force that it drives performance outside of direct competition with one's rival and even after a significant delay.

  8. How explicit and implicit test instructions in an implicit learning task affect performance.

    Directory of Open Access Journals (Sweden)

    Arnaud Witt

    Full Text Available Typically developing children aged 5 to 8 years were exposed to artificial grammar learning. Following an implicit exposure phase, half of the participants received neutral instructions at test while the other half received instructions making a direct, explicit reference to the training phase. We first aimed to assess whether implicit learning operated in the two test conditions. We then evaluated the differential impact of age on learning performances as a function of test instructions. The results showed that performance did not vary as a function of age in the implicit instructions condition, while age effects emerged when explicit instructions were employed at test. However, performance was affected differently by age and the instructions given at test, depending on whether the implicit learning of short or long units was assessed. These results suggest that the claim that the implicit learning process is independent of age needs to be revised.

  9. The Effect of Performance-Contingent Incentives when Task Complexity is Manipulated through Instruction

    2010-12-01

    Full Text Available When, and how, performance-contingent incentives improve performance is an important question fororganisations. Empirical results have been mixed – performance-contingent incentives sometimes increaseperformance, sometimes decrease performance, and sometimes have no effect. Theorists have called forfurther research to identify the effect of various moderating variables, including knowledge and taskcomplexity. This study responds by considering the role of instruction in providing the necessary knowledgeto reduce task complexity. The results suggest that a performance-contingent penalty can be a particularlyeffective means of directing effort for a simple task. For a complex task, performance can be improvedthrough instruction. The type of instruction is important – with rule-based instruction effectively directingeffort – however principle-based instruction is necessary to facilitate problem investigation and problemsolving.

    To evaluate the perception of urologists who have participated in live case demonstrations (LCDs) regarding safety, educational value/benefits, and ethics. A 19-question anonymous survey was sent to urologists who performed and/or moderated LCDs at the World Congress of Endourology meetings from 2008 to 2012. E-survey was distributed via e-mail, and automatic reminders were sent 2 weeks after original distribution if no response was obtained. Eighty-one percent (92/113) of the urologists responded to the survey of whom 75% practice full time in an academic setting. Only 48.0% were fellowship trained, however. More than 60% had performed more than five LCDs at their home and/or away institutions. Performing LCD at an away institution was associated with a higher level of anxiety when compared with performing LCDs at a home institution (79.8% vs 34.6%; Pfilm equipment and crew; audience and moderator discussions; unfamiliar team, instruments and tools; language barrier; and having to narrate the procedure, as distractors. Seventy-nine percent considered LCD as an ethical practice, and 90.5% regarded LCDs as a "beneficial" and a "great way" to educate. Similarly, considering the various factors and conditions associated with LCDs, 95% would agree to participate in another LCD. LCDs are perceived to be an effective mode of education by performers and moderators of LCDs. Standard guidelines and policies are needed, however, for the selection of patient, surgeon and team, equipment, and facility. Studies are needed to evaluate the impact of this education process.

    The World Association of Nuclear Operators, (WANO) was established in 1989 in the aftermath of the Chernobyl accident with the mission of maximizing the safety and reliability of nuclear power plants by exchanging information and encouraging communication, comparison and emulation among its members. All nuclear power stations in the world are WANO members. WANO conducted an Internal Review in 1997 and its report issued this January confirms that the WANO mission is still valid. As a result of the Internal Review, WANO is taking actions to further improve its programmes. WANO's effort to keep members conscious of safety culture in their daily work at plants is a key element for improving operational safety. WANO will be able to contribute to the future of the nuclear industry by encouraging members to actively participate in WANO programmes which are aimed at improving nuclear safety and plant performance.

    International Nuclear Information System (INIS)

    1999-01-01

    Hydro-Quebec's commitment to produce clean, renewable and safe energy was reviewed in this environmental performance report. In 1998, the utility's total installed capacity was 31,472 MW, 29,203 of which was hydroelectric. A total of 675 MW was generated by nuclear energy, and 1,594 MW was generated by thermal energy. The issue of atmospheric emissions from hydroelectric generating stations in comparison with other energy options was discussed. Hydro-Quebec takes environmental concerns into consideration at all stages in the life-cycle of its products, services and facilities, in order to meet environmental standards, prevent pollution, manage impacts at source, mitigate negative impacts and maximize positive impacts. The biggest environmental challenges facing the utility in 1998 was the January ice storm which left 40 per cent of all customers of the Distribution Division without power. More than 3,400 km of distribution lines were damaged. The system was completely restored by 1998. The main environmental consequences of the storm were spills of insulating oils, the impact on vegetation, the recovery of materials left in the field, and restoration of sites after the storm. Other highlights from 1998 include: (1) ISO 14001 implementation efforts, (2) adoption of a new environment policy, (3) participation by Hydro-Quebec in the founding of the Canadian Hydropower Association to promote the advantages of hydroelectricity to governments and the public, (4) the development of a series of measures to optimize certain generating facilities, (5) implementation of a program for evaluating the environmental compliance of all transmission substations, (6) the publication of a guide to ornamental trees and shrubs as part of the campaign to learn about the behaviour of overhanging branches which are the main cause of service interruptions on distribution lines, (7) the start up work to reinforce the transmission system, and (8) the recovery, reuse, recycling or energy

    The most important contributions of Einstein involve 5 fields of physics : the existence of quanta (light quanta, stimulated radiation emission and Bose-Einstein condensation), relativity, fluctuations (Brownian motion and thermodynamical fluctuations), the basis of quantum physics and cosmology (cosmological constant and the expansion of the universe). Diverse and renowned physicists have appreciated the development of modern physics from Einstein's ideas to the knowledge of today. This book is a collective book that gathers their work under 7 chapters: 1) 1905, a new beginning; 2) from the Einstein, Podolsky and Rosen's article to quantum information (cryptography and quantum computers); 3) the Bose-Einstein condensation in gases; 4) from stimulated emission to the today's lasers; 5) Brownian motion and the fluctuation-dissipation theory; 6) general relativity; and 7) cosmology.

    Learning outcomes may improve in graduate healthcare students when attention is given to individual learning styles. Interactive multimedia is one tool shown to increase success in meeting the needs of diverse learners. The purpose of this study was to examine the effect of learning style and type of instruction on physical therapy students' cognitive and psychomotor performance. Participants were obtained by a sample of convenience with students recruited from two physical therapy programs. Twenty-seven students volunteered to participate from Program 1. Twenty-three students volunteered to participate from Program 2. Gregorc learning styles were identified through completion of the Gregorc Style Delineator. Students were randomly assigned to one of two instructional strategies: 1) instructional CD or 2) live demonstration. Differences in cognitive or psychomotor performance following instructional multimedia based on learning style were not demonstrated in this study. Written examination scores improved with both instructional strategies demonstrating no differences between the strategies. Practical examination ankle scores were significantly higher in participants receiving CD instruction than in participants receiving live presentation. Learning style did not significantly affect this improvement. Program 2 performed significantly better on written knee and practical knee and ankle examinations. Learning style had no significant effect on student performance following instruction in clinical skills via interactive multimedia. Future research may include additional measurement instruments assessing other models of learning styles and possible interaction of learning style and instructional strategy on students over longer periods of time, such as a semester or an entire curriculum.

This paper deals with the latest state of radiation chemistry, whereas the possible practical applications are in the foreground of discussion as to reach mainly practicians in laboratory and industry. But also physicians, pharmacists and chemical engineers should be informed about the possibilities of application of high energyy radiation. Because radiation chemistry has also enriched works of related subjects, for example physical, organic and inorganic chemistry, this paper will also be of interest for experts of these disciplines.

    After the famous 1983 discovery of intermediate W, Z 0 bosons it may be stated with certainty that W, Z 0 are entirely responsible for the production of neutrinos and for their interactions. Neutrino physics notions are presented from this point of view in the first four introductory, quite elementary, paragraphs of the paper. The following seven paragraphs are more sophisticated. They are devoted to the neutrino mass and neutrino mixing question, which is the most actual problem in today neutrino physics. Vacuum neutrino oscillations, matter neutrino oscillations and netrinoless double-decay are considered. Solar neutrino physics is discussed in some detail from the point of view of vacuum and matter neutrino oscillations. The role played by neutrinos in the Universe is briefly considered. In the last paragraph there discussed the probable observation by different groups of neutrinos connected with the Supernova 1987 A: the first observation of gravitational star collapse (at least the general rehearsal of such observation) opens up a new era in astronomy of today exerimental physics and astrophysics is presented at the end of the paper in the form of a Table

    The paper discusses the precarious position of psychoanalysis, a therapeutic approach which historically has defined itself by freedom from constraint and counted treatment length not in terms of number of sessions but in terms of years, in today's era of empirically validated treatments and brief structured interventions. The evidence that exists for the effectiveness of psychoanalysis as a treatment for psychological disorder is reviewed. The evidence base is significant and growing, but less than might meet criteria for an empirically based therapy. The author goes on to argue that the absence of evidence may be symptomatic of the epistemic difficulties that psychoanalysis faces in the context of 21st century psychiatry, and examines some of the philosophical problems faced by psychoanalysis as a model of the mind. Finally some changes necessary in order to ensure a future for psychoanalysis and psychoanalytic therapies within psychiatry are suggested. PMID:16946899

    Full Text Available The prime purpose of this study was to explore a correlation between bilingual instruction in an ESL class and the class performance of the ESL learners at the secondary level. Quantitative research method was used to evaluate the test performance of 60 ESL learners divided into two groups: One was the controlled group (which was given instructions in L2 only and the other was the treatment group (which was given instructions in both L1 and L2 in Public School settings. Apart from the students, 15 language teachers’ feedback upon their perceptions of L1 usage in L2 classrooms was taken by using the Likert scale feedback forms. The results confirmed that the instructions given bilingually are directly associated to improved learner outcomes and teachers’ responses for the usage of L1 in classrooms showed a strong positive response.

  2. The Impact of Data-Based Science Instruction on Standardized Test Performance

    Herrington, Tia W.

    Increased teacher accountability efforts have resulted in the use of data to improve student achievement. This study addressed teachers' inconsistent use of data-driven instruction in middle school science. Evidence of the impact of data-based instruction on student achievement and school and district practices has been well documented by researchers. In science, less information has been available on teachers' use of data for classroom instruction. Drawing on data-driven decision making theory, the purpose of this study was to examine whether data-based instruction impacted performance on the science Criterion Referenced Competency Test (CRCT) and to explore the factors that impeded its use by a purposeful sample of 12 science teachers at a data-driven school. The research questions addressed in this study included understanding: (a) the association between student performance on the science portion of the CRCT and data-driven instruction professional development, (b) middle school science teachers' perception of the usefulness of data, and (c) the factors that hindered the use of data for science instruction. This study employed a mixed methods sequential explanatory design. Data collected included 8th grade CRCT data, survey responses, and individual teacher interviews. A chi-square test revealed no improvement in the CRCT scores following the implementation of professional development on data-driven instruction (chi 2 (1) = .183, p = .67). Results from surveys and interviews revealed that teachers used data to inform their instruction, indicating time as the major hindrance to their use. Implications for social change include the development of lesson plans that will empower science teachers to deliver data-based instruction and students to achieve identified academic goals.

    Whether older adults can compensate for their associative memory deficit by using memory strategies efficiently might depend on their general cognitive abilities. This study examined the moderating role of an IQ estimate on the beneficial effects of strategy instructions. A total of 142 participants (aged 18-85 years) received either intentional learning or strategy ("sentence generation") instructions during encoding of word pairs. Whereas young adults with a lower IQ benefited from strategy instructions, those with a higher IQ did not, presumably because they already use strategies spontaneously. Older adults showed the opposite effect: following strategy instructions, older adults with a higher IQ showed a strong increase in memory performance (approximately achieving the level of younger adults), whereas older adults with a lower IQ did not, suggesting that they have difficulties implementing the provided strategies. These results highlight the importance of the role of IQ in compensating for the aging-related memory decline.

    van Abswoude, Femke; Nuijen, Nienke B; van der Kamp, John; Steenbergen, Bert

    2018-06-01

    A large pool of evidence supports the beneficial effect of an external focus of attention on motor skill performance in adults. In children, this effect has been studied less and results are inconclusive. Importantly, individual differences are often not taken into account. We investigated the role of working memory, conscious motor control, and task-specific focus preferences on performance with an internal and external focus of attention in children. Twenty-five children practiced a golf putting task in both an internal focus condition and external focus condition. Performance was defined as the average distance toward the hole in 3 blocks of 10 trials. Task-specific focus preference was determined by asking how much effort it took to apply the instruction in each condition. In addition, working memory capacity and conscious motor control were assessed. Children improved performance in both the internal focus condition and external focus condition (ŋ p 2  = .47), with no difference between conditions (ŋ p 2  = .01). Task-specific focus preference was the only factor moderately related to the difference between performance with an internal focus and performance with an external focus (r = .56), indicating better performance for the preferred instruction in Block 3. Children can benefit from instruction with both an internal and external focus of attention to improve short-term motor performance. Individual, task-specific focus preference influenced the effect of the instructions, with children performing better with their preferred focus. The results highlight that individual differences are a key factor in the effectiveness in children's motor performance. The precise mechanisms underpinning this effect warrant further research.

  2. Verbal-motor attention-focusing instructions influence kinematics and performance on a golf-putting task.

    Munzert, Jörn; Maurer, Heiko; Reiser, Mathias

    2014-01-01

    The authors examined how varying the content of verbal-motor instructions and requesting an internal versus external focus influenced the kinematics and outcome of a golf putting task. On Day 1, 30 novices performed 120 trials with the instruction to focus attention either on performing a pendulum-like movement (internal) or on the desired ball path (external). After 20 retention trials on Day 2, they performed 20 transfer trials with the opposite instruction. Group differences for retention and a group by block interaction showed that external instruction enhanced movement outcome. Kinematic data indicated that specific instruction content influenced outcomes by eliciting changes in movement execution. Switching from the external to the internal focus instruction resulted in a more pendulum-like movement.

    Kumaran, Dharshan; Ludwig, Hans

    2013-12-01

    The transitive inference (TI) paradigm has been widely used to examine the role of the hippocampus in generalization. Here we consider a surprising feature of experimental findings in this task: the relatively poor transitivity performance and levels of hierarchy knowledge achieved by adult human subjects. We focused on the influence of the task instructions on participants' subsequent performance--a single-word framing manipulation which either specified the relation between items as transitive (i.e., OLD-FRAME: choose which item is "older") or left it ambiguous (i.e., NO-FRAME: choose which item is "correct"). We show a marked but highly specific effect of manipulating prior knowledge through instruction: transitivity performance and levels of relational hierarchy knowledge were enhanced, but premise performance unchanged. Further, we show that hierarchy recall accuracy, but not conventional awareness scores, was a significant predictor of inferential performance across the entire group of participants. The current study has four main implications: first, our findings establish the importance of the task instructions, and prior knowledge, in the TI paradigm--suggesting that they influence the size of the overall hypothesis space (e.g., to favor a linear hierarchical structure over other possibilities in the OLD-FRAME). Second, the dissociable effects of the instructional frame on premise and inference performance provide evidence for the operation of distinct underlying mechanisms (i.e., an associative mechanism vs. relational hierarchy knowledge). Third, our findings suggest that a detailed measurement of hierarchy recall accuracy may be a more sensitive index of relational hierarchy knowledge, than conventional awareness score--and should be used in future studies investigating links between awareness and inferential performance. Finally, our study motivates an experimental setting that ensures robust hierarchy learning across participants

  7. How "fun/importance" fit affects performance: relating implicit theories to instructions.

    Bianco, Amy T; Higgins, E Tory; Klem, Adena

    2003-09-01

    People experience a regulatory fit when they employ means of goal pursuit that fit their regulatory orientation, and this fit increases motivation that can enhance performance. The present studies extend previous research on regulatory fit to the classic motivational variables of fun and importance. They also examine for the first time the effect on performance of the fit between individuals' implicit theories about a task's fun or importance and their strategic engagement of the task as fun or important as induced by task instructions. In all three studies, task performance was better when the external task instructions "fit" rather than did not fit participants' implicit theory for the task. The implications of these findings for understanding the motivational effects of fun and importance are discussed.

    This preliminary study developed pre-performance routines for tenpin bowlers and instructed them. To develop the routine, the situations before throwing the ball were divided into four phases; participants were examined through interviews and observations. This study used an A-B design; the A stage included the development of the routines for 3 wk., while the B stage included the instruction and two evaluations of the routine consistency. Practice was implemented for 4 hr. per day for 9 wk. The participants noted they understood the developed routine easily and experienced an atmosphere similar to that of a competition during training through the routines. They found it difficult to practice the relaxation phase, but emphasized that the relaxation phase was helpful. Consistent routines were associated with an improved mental state and performance in a competition. This study suggests that pre-performance routines stabilize the mental state of the athletes, apparently giving them a competitive advantage.

    Full Text Available This study aimed to assess the instructional performance of teacher education faculty members in one State University in the Philippines as perceived by themselves and CTE students during the Academic Year 2012-2013 with the end view of formulating an action plan to enhance the aforementioned situation. The study utilized the descriptive method of research. This method attempted to ascertain the prevailing conditions and sought to answer questions to the real facts relating to the existing conditions. Results found that instructors/professors perceived their instructional performance as very good. Faculty respondents believed that they are qualified to teach the subjects they are handling. This was manifested by having good interaction between them and the students inside the classroom, by way of assessing their performance tasks and by way of assessing through pencil-paper test. However, student respondents perceived that the instructor/professors’ instructional performance were only satisfactory. They perceived that CTE faculty members are all in better position to handle the subjects assigned to them. Interaction between them was effective. Relative to the findings, it is recommended that instructors/professors should exercise their full potential in teaching so as to become excellent.

    2010-01-01

    Current Advanced Cardiac Life Support (ACLS) course instruction involves a 2-day course with traditional lectures and limited team interaction. We wish to explore the advantages of a scenario-based performance-oriented team instruction (SPOTI) method to implement core ACLS skills for non-English-speaking international paramedic students. The objective of this study was to determine if scenario-based, performance-oriented team instruction (SPOTI) improves educational outcomes for the ACLS instruction of Korean paramedic students. Thirty Korean paramedic students were randomly selected into two groups. One group of 15 students was taught the traditional ACLS course. The other 15 students were instructed using a SPOTI method. Each group was tested using ACLS megacode examinations endorsed by the American Heart Association. All 30 students passed the ACLS megacode examination. In the traditional ACLS study group an average of 85% of the core skills were met. In the SPOTI study group an average of 93% of the core skills were met. In particular, the SPOTI study group excelled at physical examination skills such as airway opening, assessment of breathing, signs of circulation, and compression rates. In addition, the SPOTI group performed with higher marks on rhythm recognition compared to the traditional group. The traditional group performed with higher marks at providing proper drug dosages compared to the SPOTI students. However, the students enrolled in the SPOTI method resulted in higher megacode core compliance scores compared to students trained in traditional ACLS course instruction. These differences did not achieve statistical significance due to the small sample size. Copyright 2010 Elsevier Inc. All rights reserved.

    2015-05-01

    Survival from out-of-hospital cardiac arrest is increased by bystander cardiopulmonary resuscitation (CPR). Bystander performance can be improved when CPR instructions are delivered by a calltaker at the Emergency Communications Centre. Little is known about a young person's ability to understand these instructions and perform CPR correctly. We assessed the ability of a group of untrained young people to effectively apply these directions to an adult resuscitation manikin. 87 youngsters aged 7-15 years with no previous training in CPR were separately equipped with a mobile phone and an adult assessment manikin. They phoned the emergency number (111) and were automatically diverted to a senior emergency medical dispatcher (EMD). The EMD delivered resuscitation instructions which complied fully with Medical Priority Dispatch System (version 12.1). Performance was monitored using a Laerdal Computerised Skill Reporting System. Average compression depth increased with age from 10.3 mm to 30 mm for 8 and 15 year olds respectively. 100 compressions per minute was achieved in youngsters aged 10 years and older but the rate fatigued over time and improved after interruption for two ventilations. Those aged 11 years and older consistently compressed the chest from 31 mm to 50mm. Only one participant could successfully ventilate the manikin by mouth-to-mouth. This study demonstrates that untrained youngsters should perform compression-only CPR. From 11 years of age, they can effectively perform dispatcher-directed CPR by compressing the chest at an appropriate rate and depth. However, their technique benefits from formal training.

    For reasons of bureaucracy and safety, astronauts on the International Space Station are provided with excruciatingly detailed instructions and a lack of decision-making power, even for simple routine tasks. Besides being time-consuming, many astronauts report feelings of demotivation, irritation, and even defiance when confronted with this working method. Anecdotic evidence suggests that this method leads to situations where astronauts read instructions diagonally or avoid checking in with mission support, thereby ironically increasing the risk of error making. There is a need to consider under which circumstances, for whom, and why the provision of long instructions could be detrimental for well-being and performance. An experimental study with LEGO assembly tasks examined whether length of instructions (i.e. short versus long) and task complexity (simple vs. complex) impact negative affect, motivational experiences and performance of participants (N = 113, Mage = 18.75 ± 2.46 years). Long instructions for simple tasks provoked greater feelings of irritation, diminished the perceived value of instructions, and negatively influenced productivity and accuracy. The negative effect of long instructions on irritation was explained via decreased perceived value. Additionally, the effect of length of instructions on irritation differed for participants high versus those low in need for achievement.

    Full Text Available Technology mediated learning brings together the users with shared interests. This method makes learners informally engaged in language learning. This study intended to investigate the effect of technology mediated instruction on cognitive scaffolding, academic performance and motivation. Employing a quasi-experimental research, 80 learners from two intact classes at Islamic Azad University, Osku Branch were selected as the experimental and control groups. Telegram as a tool was used in the experimental group, while the control group received traditional way of instruction. Critical ethnography approach was implemented to consider the amount of cognitive scaffolding. To measure the students’ motivational level in both groups, Course Interest Survey (CIS was administered at the end of the semester. The total average score for each group was calculated. To compare students’ academic achievement, their average scores in the final academic test were considered. An Independent samples t-test in was used to compare the mean scores. The results indicated that technology mediated learning brought about cognitive scaffolding and the students in the experimental group outperformed the control group in terms of motivation and academic achievement. The results of the study suggest that to bring about academically successful students, practitioners should use technology mediated instruction.

    Full Text Available This study was conducted to systematically track and benchmark upper primary school students‟ ESL reading comprehension ability and subsequently generate data at the micro and macro levels according to individual achievement, school location, gender and ethnicity at the school, district, state and national levels. The main intention of this initiative was to provide information to assist ESL teachers about their students‟ reading ability and to determine students' reading comprehension performance standards. The auto generated data is expected to facilitate classroom instructional process without necessitating teachers to prepare test materials or manage data of their students‟ reading comprehension track records. The respondents were 1,514 Year 5 students from urban and rural schools from a district in northern Malaysia. The idea was conceptualised through a series of tests and development of the Reading Evaluation and Decoding System (READS for Primary Schools. The findings indicated that majority of the respondents were „below standard‟ and „at academic warning‟. We believe the generated data can assist the Ministry of Education to develop better quality instructional processes that are evidence based with a more focused reading instruction and reading material to tailor to the needs of students.

In general, today's customers for superconductive equipment want the highest possible performance, almost regardless of cost. The products operate within a few degrees of absolute zero, and virtually all are fabricated from niobium or niobium alloys-so far the high-temperature superconductors discovered in 1986 and 1987 have had no impact on these markets. The industry shows potential and profound societal impact, even without the new materials

  18. Enhancing student performance: Linking the geography curriculum, instruction, and assessment in the English-speaking Caribbean

    Collymore, Jennifer C.

    In a 21st century knowledge society individuals are expected to use their knowledge and skills to think critically, problem solve, make decisions, comprehend new ideas, communicate, and collaborate effectively with others. Helping students achieve this level of performance is no easy task and it brings into focus the fact that the effectiveness of any education system rests on the systemic coordination or alignment of three crucial components: curriculum, instruction and assessment (referred to as the CIA). These components must work in concert to facilitate and enhance student performance. However, educational reform typically targets these components in isolation, often treating only one component, rather than the system as a whole. The misalignment of these components can adversely affect student performance in any discipline. When the CIA components are out of alignment, it is difficult to evaluate student and system performance and achieve improvement in an educational system. Therefore, using geography education in Trinidad & Tobago as a case study, this study examined the nature of the alignment among the CIA components in the advanced geography system in the English- Speaking Caribbean and the extent to which the alignment may be affecting student performance. The study sought to determine the possible sources and causes of misalignment, the challenges to achieving alignment, and ways of achieving greater coordination among the CIA components of the system. The methodology employed in the study involved the use of classroom observations, interviews, and the Surveys of Enacted Curriculum Alignment Model which uses content analyses and surveys. The results showed that there were varying degrees of alignment among the components. There was acceptable alignment (Alignment Index ≥ 0.25) between the curriculum and assessment. However, the alignment between curriculum and instruction or assessment and instruction was poor (Alignment Index ≤ 0.12). The baseline

    Torso-based vibrotactile feedback has been shown to improve postural performance during quiet and perturbed stance in healthy young and older adults and individuals with balance impairments. These systems typically include tactors distributed around the torso that are activated when body motion exceeds a predefined threshold. Users are instructed to "move away from the vibration". However, recent studies have shown that in the absence of instructions, vibrotactile stimulation induces small (~1°) non-volitional responses in the direction of its application location. It was hypothesized that an attractive cuing strategy (i.e., "move toward the vibration") could improve postural performance by leveraging this natural tendency. Eight healthy older adults participated in two non-consecutive days of computerized dynamic posturography testing while wearing a vibrotactile feedback system comprised of an inertial measurement unit and four tactors that were activated in pairs when body motion exceeded 1° anteriorly or posteriorly. A crossover design was used. On each day participants performed 24 repetitions of Sensory Organization Test condition 5 (SOT5), three repetitions each of SOT 1-6, three repetitions of the Motor Control Test, and five repetitions of the Adaptation Test. Performance metrics included A/P RMS, Time-in-zone and 95 % CI Ellipse. Performance improved with both cuing strategies but participants performed better when using repulsive cues. However, the rate of improvement was greater for attractive versus repulsive cuing. The results suggest that when the cutaneous signal is interpreted as an alarm, cognition overrides sensory information. Furthermore, although repulsive cues resulted in better performance, attractive cues may be as good, if not better, than repulsive cues following extended training.

    This study establishes the effects of a flipped classroom model of instruction on academic performance and attitudes of 66 first-year secondary school students towards chemistry. A pre-test and post-test experimental design was employed to assign students randomly into either the experimental or control group. In order to assess the suitability of using flipped model of instruction, students were divided in two groups. For the first group called the experimental group, a "flipped classroom" was used in which the students were given video lessons and reading materials, before the class to be revised at home. On the other hand, the second group followed traditional methodology, and it was used as control. The rate of reaction knowledge test and the chemistry attitude scale were administered. In addition, the researcher documented classroom observations, experiences, thoughts and insights regarding the intervention in a journal on a daily basis in order to enrich the data. Students were interviewed at the end of the research in order to enrich the qualitative data also. Findings from this study reveal that the flipped instruction model facilitates a shift in students' conceptual understanding of the rate of chemical reaction significantly more than the control condition. Positive significant differences were found on all assessments with the flipped class students performing higher on average. Students in the flipped classroom model condition benefited by preparing for the lesson before the classes and had the opportunity to interact with peers and the teacher during the learning processes in the classroom. The findings support the notion that teachers should be trained or retrained on how to incorporate the flipped classroom model into their teaching and learning processes because it encourages students to be directly involved and active in the learning.

    Full Text Available This study aimed to determine the effects of flipped instruction on the performance and attitude of high school students in Mathematics. The study made use of the true experimental design, specifically the pretest-posttest control group design. There were two instruments used to gather data, the pretest-posttest which was subjected to validity and reliability tests and the Modified Fennema-Sherman Attitudes Scale. It was found out that the experimental and control groups were comparable in the pretest and posttest. Comparison on their gain scores revealed significant difference with performance of the experimental group higher than the control group. There was no significant difference on the level of attitude of the participants in the experimental group before and after the study in terms of confidence in learning mathematics, attitude toward success in mathematics, mathematics anxiety and perception of teacher's attitudes. A very weak positive relationship existed between performance and attitudes toward mathematics.

    This paper reports on an experiment investigating the expressive means with which performers of groove-based musics signal the intended timing of a rhythmic event. Ten expert drummers were instructed to perform a rock pattern in three different tempi and three different timing styles: "laid-back," "on-the-beat," and "pushed." The results show that there were systematic differences in the intensity and timbre (i.e., sound-pressure level, temporal centroid, and spectral centroid) of series of snare strokes played with these different timing styles at the individual level. A common pattern was found across subjects concerning the effect of instructed timing on sound-pressure level: a majority of the drummers played laid-back strokes louder than on-the-beat strokes. Furthermore, when the tempo increased, there was a general increase in sound-pressure level and a decrease in spectral centroid across subjects. The results show that both temporal and sound-related features are important in order to indicate that a rhythmic event has been played intentionally early, late, or on-the-beat, and provide insight into the ways in which musicians communicate at the microrhythmic level in groove-based musics.

    Full Text Available In many of the secondary classrooms across the country, students are passively engaged in the mathematics content, and academic performance can be described, at best, as mediocre. This research study sought to bring about improvements in student engagement and performance in the secondary mathematics classroom through the implementation of the flipped model of instruction and compared student interaction in the flipped classroom with a traditional format. The flipped model of instruction is a relatively new teaching strategy attempting to improve student engagement and performance by moving the lecture outside the classroom via technology and moving homework and exercises with concepts inside the classroom via learning activities. Changes in the student participants’ perceptions and attitudes were evidenced and evaluated through the completion of a pre- and post-survey, a teacher-created unit test, random interviews, and a focus group session. In addition, the researcher documented observations, experiences, thoughts, and insights regarding the intervention in a journal on a daily basis. Quantitative results and qualitative findings revealed the student participants responded favorably to the flipped model of instruction and experienced an increase in their engagement and communication when compared to the traditional classroom experience. The student participants also recognized improvements in the quality of instruction and use of class of time with the flipped model of instruction. In terms of academic performance, no significant changes were demonstrated between the flipped model of instruction students and those taught in a traditional classroom environment.

  5. The Effects of Blended Instruction on Oral Reading Performance and their Relationships to a Five-Factor Model of Personality

    Full Text Available In recent times, 'Blended Instruction' - an effective method of instructions utilizing e-Learning materials in English education - consists of an individual learning part, a collaborative learning part and a teacher instruction part. In the individual learning, students act out model dialogues in the WBT courseware which incorporated a high quantity of video and sound clips. In the collaborative learning, students perform the dialogues in pairs and assessed each other's performance. Our recent research in a high school showed that the skill of the students' oral reading was improved in most criteria of assessment through blended instruction. However, it is still not clear what kind of relationship exists between the development of the students' oral reading skills and their personalities. With this in mind, the authors have studied the effects of the blended instruction on the junior high school students' oral reading performance and their relationships to the five-factor model of personality. The result of the research shows that the skill of the students' oral reading was improved in most criteria of assessment and the blended instruction was effective for the personality group, 'Introverted unintelligent person' in the most categories of oral reading criteria as well as the personality group, 'Sociable hard-worker'. The important factor for that group in oral reading performance turned out to be 'Sense Reading'.

    We examined the influence of instructions on decision-making accuracy using video simulations of game-specific scenarios in Australian football. Skilled performers (average age of 23.4 ± 4.2 years) differing in experience (range 0 to 339 Australian Football League (AFL) matches) assumed the role of the key attacker and verbally indicated their kicking decision. Participants were randomly stratified into three groups: (1) LOOSE (n = 15)--instructed to "keep the ball away from the loose defender"; (2) TTF (n = 15) - instructed to "take the first option"; and (3) NI (control) (n = 16)--given no instructions. Gaze behaviour for a subset of participants (n = 20) was recorded. In the scenarios with an even number of attacking and defensive players, the decision-making accuracy of LOOSE was greater than TTF. This difference was most evident for lesser experienced performers, highlighting that lesser experienced performers are more affected by instructional foci than experienced performers. Gaze behaviour was not affected by instructional foci, but visual search rate was greater in scenarios of greater player number and complexity.

    Full Text Available Learning a foreign language offers a great challenge to students since it involves learning different skills and subskills. Quite a few number of researches have been done so far on the relationship between gender and learning a foreign language. On the other hand, two major approaches in teaching grammar have been offered by language experts, inductive and deductive. The present study examines which method of teaching grammar is more fruitful for Iranian male and female students. For this purpose, 150 freshman students, 110 females and 40 males, majoring in English were selected from all available students at Abadeh and Shiraz Azad universities. All the subjects took the NTC's grammar test prior to the instruction as pre-test. Then, they were divided into two groups and were taught grammar inductively and deductively in each group for one semester. At the end of the instruction, the same test was taken as post-test. The comparison between the students' pre and post-test indicated that there was a significant improvement in their knowledge of grammar. By the way, through a two-way ANOVA, it was found out that males learned grammar better when they were taught inductively and females showed a better performance when they were taught deductively.

    This study examined students' technical performances improvements in three track and field events (hurdles, shot put, and long jump) following either a Sport Education season or a Direct Instruction unit. An experienced Physical Education teacher taught two classes totalling 47 sixth-grade students (25 boys and 22 girls, aged between 10 and 13 years old) in 20, 45-minute lessons over 10 weeks. The students' technical performances were analysed and evaluated through systematic observation of videos. The Wilcoxon signed-rank test was used to compare scores at three time points (pre-test, post-test and retention), and the Mann-Whitney U test was used to examine the differences within each instructional model at each assessment moment, as well as by gender and skill level. The impact of each instructional model in student learning was markedly distinct. While in Sport Education students of both genders and skill levels improved significantly in all events, in Direct Instruction, evidence of significant improvements was limited to boys and students of higher skill level. Key pointsThe impact of each teaching approach in student learning was distinct. While in Sport Education the technical performance improvements spread throughout students of both genders and skill levels, in Direct Instruction significant improvements were exclusive to boys and students of higher skill level.The extended analysis in the current study, taking into account student gender and skill level, permitted a more comprehensive measure of the learning impact of the two approaches. More sophisticated analyses of the tasks and instructional strategies of each approach are encouraged.

  2. Location versus task relevance: The impact of differing internal focus of attention instructions on motor performance.

    Pelleck, Valerie; Passmore, Steven R

    2017-05-01

    Impaired performance while executing a motor task is attributed to a disruption of normal automatic processes when an internal focus of attention is used. What remains unclear is whether the specificity of internally focused task instructions may impact task performance. The present study assessed the implications of changing the attentional focus of novice and skilled golfers by measuring behavioural, neurophysiological and kinematic changes during a golf putting task. Over six blocks of ten putting trials each, attention was directed either externally (towards the target) or internally in one of two ways: 1) proximal (keeping the elbows extended and the hands gripping the putter); or 2) distal (keeping the weight evenly distributed between both legs) to the critical elements of the task. Results provided evidence that when novice participants use an internal focus of attention more closely associated with task performance that their: 1) execution; 2) accuracy; 3) variability of surface electromyography (sEMG) activity; and 4) kinematics of the putter movement are all adversely affected. Skilled golfers are much more resilient to changes in attentional focus, while all participants interpret a distal internal focus of attention similar to an external focus. All participants produced decreased activity in the muscle (tibialis anterior) associated with the distal (less task relevant) focus of attention even when the "internal" focus was on the lower extremity. Our results provide evidence that the skill level of the participant and the distance of the internal focus of attention from the key elements of a motor skill directly impact the execution, muscle activity, and movement kinematics associated with skilled motor task performance.

    Full Text Available Creative Arts is a core and compulsory subject in Nigerian upper basic classes, but the students’ performance over the years indicated high failure. Instructional strategies play a pivotal role in improving students’ performance. Computer-based instructions such as animated drawings could be a possible solution. This research adopted the design and development type. The between groups repeated measure design compared pretest and post-test scores of participants to identify differences after treatment. To validate the instruments, test re-test method was used; Pearson product moment correlation co-efficient yielded a reliability value of .94. Also, 674 upper basic school students consisting of 387 public and 287 private schools students, 338 males, and 336 females were involved in the study. Seven research questions and seven corresponding hypotheses were raised and tested respectively. ANOVA and t-test were used for hypotheses testing. Findings of the study showed that computer-based animated drawings instruction enhanced performance. It was recommended among others that the classroom teacher should embrace the strategy for Creative Arts classes; authors and curriculum planners should create more opportunities for computer-based animated drawing in explaining procedures for instruction to enhance learning and improve performance.

  11. A dissociation between engagement and learning: Enthusiastic instructions fail to reliably improve performance on a memory task.

    Directory of Open Access Journals (Sweden)

    Benjamin A Motz

    Full Text Available Despite widespread assertions that enthusiasm is an important quality of effective teaching, empirical research on the effect of enthusiasm on learning and memory is mixed and largely inconclusive. To help resolve these inconsistencies, we conducted a carefully-controlled laboratory experiment, investigating whether enthusiastic instructions for a memory task would improve recall accuracy. Scripted videos, either enthusiastic or neutral, were used to manipulate the delivery of task instructions. We also manipulated the sequence of learning items, replicating the spacing effect, a known cognitive technique for memory improvement. Although spaced study reliably improved test performance, we found no reliable effect of enthusiasm on memory performance across two experiments. We did, however, find that enthusiastic instructions caused participants to respond to more item prompts, leaving fewer test questions blank, an outcome typically associated with increased task motivation. We find no support for the popular claim that enthusiastic instruction will improve learning, although it may still improve engagement. This dissociation between motivation and learning is discussed, as well as its implications for education and future research on student learning.

We did, however, find that enthusiastic instructions caused participants to respond to more item prompts, leaving fewer test questions blank, an outcome typically associated with increased task motivation. We find no support for the popular claim that enthusiastic instruction will improve learning, although it may still improve engagement. This dissociation between motivation and learning is discussed, as well as its implications for education and future research on student learning.

  14. Analysis of the Sheltered Instruction Observation Protocol Model on Academic Performance of English Language Learners

    Science.gov (United States)

    Ingram, Sandra W.

    This quantitative comparative descriptive study involved analyzing archival data from end-of-course (EOC) test scores in biology of English language learners (ELLs) taught or not taught using the sheltered instruction observation protocol (SIOP) model. The study includes descriptions and explanations of the benefits of the SIOP model to ELLs, especially in content area subjects such as biology. Researchers have shown that ELLs in high school lag behind their peers in academic achievement in content area subjects. Much of the research on the SIOP model took place in elementary and middle school, and more research was necessary at the high school level. This study involved analyzing student records from archival data to describe and explain if the SIOP model had an effect on the EOC test scores of ELLs taught or not taught using it. The sample consisted of 527 Hispanic students (283 females and 244 males) from Grades 9-12. An independent sample t-test determined if a significant difference existed in the mean EOC test scores of ELLs taught using the SIOP model as opposed to ELLs not taught using the SIOP model. The results indicated that a significant difference existed between EOC test scores of ELLs taught using the SIOP model and ELLs not taught using the SIOP model (p = .02). A regression analysis indicated a significant difference existed in the academic performance of ELLs taught using the SIOP model in high school science, controlling for free and reduced-price lunch (p = .001) in predicting passing scores on the EOC test in biology at the school level. The data analyzed for free and reduced-price lunch together with SIOP data indicated that both together were not significant (p = .175) for predicting passing scores on the EOC test in high school biology. Future researchers should repeat the study with student-level data as opposed to school-level data, and data should span at least three years.

    The first generation of mergers and managed care hasn't slowed down group practices' need for strategic planning. Even groups that already went through one merger are asking about new mergers or ownership possibilities, the future of managed care, performance standards and physician unhappiness. Strategic planning, including consideration of bench-marking, production of ancillary services and physician involvement, can help. Even if only a short, general look at the future, strategic planning shows the proactive leadership needed in today's environment.

  1. Verbal Instructions Acutely Affect Drop Vertical Jump Biomechanics--Implications for Athletic Performance and Injury Risk Assessments.

    Science.gov (United States)

    Khuu, Steven; Musalem, Lindsay L; Beach, Tyson A C

    2015-10-01

    Biomechanical quantities acquired during the drop vertical jump (DVJ) are used in the assessment of athletic performance and injury risk. The objective was to examine the impact of different verbal instructions on spatiotemporal, kinematic, and kinetic variables commonly included in such assessments. Ten men and 10 women from local varsity and club volleyball, basketball, figure skating, and track and field teams volunteered to participate. The athletes performed DVJs after given instructions to minimize ground contact time (CT), maximize jump height (HT), and synchronously extend the lower extremity joints (EX). Between the CT, HT, and EX conditions, body segment and joint angles were compared together with characteristics of vertical ground reaction force (GRF), whole-body power output, stiffness, and center-of-mass displacement time histories. Verbal instructions were found to influence nearly all of the spatiotemporal, body segment and joint kinematic, and kinetic variables that were statistically analyzed. Particularly noteworthy was the finding that athletic performance indices (e.g., jump height, power output, vertical stiffness, and reactive strength index) and lower extremity injury risk markers (e.g., peak vertical GRF and frontal plane knee angle) were significantly different (p ≤ 0.05) between the CT, HT, and EX conditions. The findings of this study suggest that verbal instructions should be controlled and/or clearly documented when using the DVJ to assess athletic performance potential and injury risk. Moreover, practitioners who devise performance enhancement and injury prevention strategies based on DVJ assessments are advised to consider that "coaching" or "cueing" during the task execution could impact conclusions drawn.

    2017-06-01

    Full Text Available Using Trends in International Mathematics and Science Study (TIMSS 2011 eighth-grade international dataset, this study explored the profiles of instructional practices reported by high- and low-performing mathematics teachers across the US, Finland, Korea, and Russia. Concepts of conceptual teaching and procedural teaching were used to frame the design of the current study. Latent cluster analysis was applied in the investigation of the profiles of mathematics teachers’ instructional practices across the four education systems. It was found that all mathematics teachers in the high- and low-performing groups used procedurally as well as conceptually oriented practices in their teaching. However, one group of high-performing mathematics teachers from the U.S. sample and all the high-performing teachers from Finland, Korea, and Russia showed more frequent use of conceptually oriented practices than their corresponding low-performing teachers. Another group of U.S. high-performing mathematics teachers showed a distinctive procedurally oriented pattern, which presented a rather different picture. Such results provide useful suggestions for practitioners and policy makers in their effort to improve mathematics teaching and learning in the US and in other countries as well.DOI: http://dx.doi.org/10.22342/jme.8.2.4066.115-132

    Full Text Available There are three urgent tasks before the Serbian lexicographers: the vertical and horizontal defining of the contemporary Serbian language, the formation of the Serbian language corpus and the compilation of the standard descriptive dictionary: the first two tasks should be done by the Serbian linguists and by those dealing with corpora, whereas the third should be trusted to the Serbian lexicographers, both the present and the future ones. The Serbian lexicographers, the members of the Belgrade school of lexicography, who have compiled 20 volumes of the Serbian Academy of Arts and Sciences Dictionary, six-volume Matica Srpska Dictionary, and single-volume Matica Srpska Dictionary, and outstanding Belgrade lexicologists will doubtless create a modern and reliable conception of such a dictionary, make precise working instructions based on contemporary linguistic and lexicological knowledge if the project is supported by the government. Hopefully, this extremely significant national undertaking will be completed in a few years.

    Visser, Yusra Laila

    This study compared the effect of lecture-based instruction to that of problem-based instruction on learner performance (on near-transfer and far-transfer problems), problem solving processes (reasoning strategy usage and reasoning efficiency), and attitudes (overall motivation and learner confidence) in a Genetics course. The study also analyzed the effect of self-regulatory skills and prior-academic achievement on performance for both instructional strategies. Sixty 11th grade students at a public math and science academy were assigned to either a lecture-based instructional strategy or a problem-based instructional strategy. Both treatment groups received 18 weeks of Genetics instruction through the assigned instructional strategy. In terms of problem solving performance, results revealed that the lecture-based group performed significantly better on near-transfer post-test problems. The problem-based group performed significantly better on far-transfer post-test problems. In addition, results indicated the learners in the lecture-based instructional treatment were significantly more likely to employ data-driven reasoning in the solving of problems, whereas learners in the problem-based instructional treatment were significantly more likely to employ hypothesis-driven reasoning in problem solving. No significant differences in reasoning efficiency were uncovered between treatment groups. Preliminary analysis of the motivation data suggested that there were no significant differences in motivation between treatment groups. However, a post-research exploratory analysis suggests that overall motivation was significantly higher in the lecture-based instructional treatment than in the problem-based instructional treatment. Learner confidence was significantly higher in the lecture-based group than in the problem-based group. A significant positive correlation was detected between self-regulatory skills scores and problem solving performance scores in the problem

    The role of knee arthrography today is demonstrated and technical problems are discussed. Among a lot of variants the position of the patient and the choice of contrast media play a great part concerning the result of the examination. Mild complications occur in 0.25% of the examinations, severe and live threatening complications are extremely rare. Diagnosis of meniscal lesions is most important for knee arthrography; arthroscopy and arthrography are complementary examinations and not mutually exclusive, they achieve combined an accuracy of 97-98%. In the same way arthrography is able to evaluate the condropathy of the femoro-tibial joint, whereas accuracy of arthroscopy in the diagnosis of patellar chondropathy is much higher. There is a great reliability of arthrography regarding the evaluation of lesions of the capsule, but accuracy in lesions of the cruciate ligaments is low. Arthrography is very suitable for evaluation of Baker-cysts, since indications for almost occuring internal derangement of the knee are even available. Knee arthrography is a complex and safe procedure with very less discomfort for the patient; it has a central position in the evaluation of lesions of the knee. (orig.) [de

    Part I of this contribution on innovative nuclear fuels gives a summary of current developments and problems of today's fuels, i.e. enriched UO 2 and UO 2 with a few % of PUO 2 (MOX fuel) or Gd 2 O 3 (as burnable neutron poison). The problems and property changes caused by high burnups (e.g. degradation of the thermal conductivity, polygonization or formation of the rim-structure) are discussed. Subsequently, the concepts for new fuels to burn excess Pu and to achieve an effective transmutation of the minor actinides Np, Am and Cm are treated. The criteria for the choice of suitable fuels and different fuel types (high Pu-content fuels, nitrides, U-free fuels, inert matrix supported fuels, cercers, cermets, etc.) are discussed. Part II of this contribution on innovative nuclear fuels deals with the properties of relevance of the different materials suggested to be used in innovative fuels which range from pure actinide fuel such as PuN and AmO 2 to spinel MgAl 2 O 4 and zircon ZrSiO 4 for inert matrix-based fuels, etc. The available knowledge on materials research aspects is summarized with emphasis on the physics of radiation damage. It is shown that significant gaps in the present knowledge exist, e.g. for the minor actinide compounds, and suggestions are made to fill these gaps in order to achieve a sufficient data base to design and operate suitable innovative fuels in a near future.

  11. Benchmarking to the world's best in mathematics. Quality control in curriculum and instruction among the top performers in the TIMSS.

    Science.gov (United States)

    Phelps, R P

    2001-08-01

    This article describes the education quality control systems (for mathematics) used by those countries that performed best on the Third International Mathematics and Science Study (TIMSS). Enforced quality control measures are defined as "decision points"--where adherence to the curriculum and instruction system can be reinforced. Most decision points involve stakes for the student, teacher, or school. They involve potential consequences for failure to adhere to the system and to follow the program at a reasonable pace. Generally, countries with more decision points perform better on the TIMSS. When the number of decision points and TIMSS test scores are adjusted for country wealth, the relationship between the degree of (enforced) quality control and student achievement appears to be positive and exponential. The more (enforced) quality control measures employed in an education system, the greater is students' academic achievement.

    Look, Clarisse; McCabe, Patricia; Heard, Robert; Madill, Catherine J

    2018-02-02

    Modeling and instruction are frequent components of both traditional and technology-assisted voice therapy. This study investigated the value of video modeling and instruction in the early acquisition and short-term retention of a complex voice task without external feedback. Thirty participants were randomized to two conditions and trained to produce a vocal siren over 40 trials. One group received a model and verbal instructions, the other group received a model only. Sirens were analyzed for phonation time, vocal intensity, cepstral peak prominence, peak-to-peak time, and root-mean-square error at five time points. The model and instruction group showed significant improvement on more outcome measures than the model-only group. There was an interaction effect for vocal intensity, which showed that instructions facilitated greater improvement when they were first introduced. However, neither group reproduced the model's siren performance across all parameters or retained the skill 1 day later. Providing verbal instruction with a model appears more beneficial than providing a model only in the prepractice phase of acquiring a complex voice skill. Improved performance was observed; however, the higher level of performance was not retained after 40 trials in both conditions. Other prepractice variables may need to be considered. Findings have implications for traditional and technology-assisted voice therapy. Copyright © 2017 The Voice Foundation. Published by Elsevier Inc. All rights reserved.

    Background—Skateboarding injuries have increased with the rise in popularity of the sport, and the injury pattern can be expected to have changed with the development of both skateboard tricks and the materials used for skateboard construction. Objective—To describe the injury pattern of today. Methods—The pattern of injuries, circumstances, and severity were investigated in a study of all 139 people injured in skateboarding accidents during the period 1995–1998 inclusive and admitted to the University Hospital of Umeå. This is the only hospital in the area, serving a population of 135 000. Results—Three of the 139 injured were pedestrians hit by a skateboard rider; the rest were riders. The age range was 7–47 years (mean 16). The severity of the injuries was minor (AIS 1) to moderate (AIS 2); fractures were classified as moderate. The annual number of injuries increased during the study period. Fractures were found in 29% of the casualties, and four children had concussion. The most common fractures were of the ankle and wrist. Older patients had less severe injuries, mainly sprains and soft tissue injuries. Most children were injured while skateboarding on ramps and at arenas; only 12 (9%) were injured while skateboarding on roads. Some 37% of the injuries occurred because of a loss of balance, and 26% because of a failed trick attempt. Falls caused by surface irregularities resulted in the highest proportion of the moderate injuries. Conclusions—Skateboarding should be restricted to supervised skateboard parks, and skateboarders should be required to wear protective gear. These measures would reduce the number of skateboarders injured in motor vehicle collisions, reduce the personal injuries among skateboarders, and reduce the number of pedestrians injured in collisions with skateboarders.

    Full Text Available Economic education in Romania has gone through many changes in recent years, in order to modernize and adapt to the requirements of the economy based on knowledge. But, regardless of the stage, students satisfaction is a key criterion for assessing the relevance and the accomplishment of the mission of universities in society. The highest satisfaction should be a constant concern for managers of higher education institutions. In order to achieve this goal, it is very important to periodically determine which are the most significant factors for students, how satisfied are they and which is the performance of the higher education for these attributes. The knowledge transfer process and the degree to which we can speak of a modern university tailored to the needs of the business environment and focused on increasing the relevance of the educational process for the labour market can be appreciated taking into consideration the content of the educational activities. The objective of this research is to identify relationships between the importance, satisfaction and performance of the instructional process in the process of improvement of the university management and the creation of better university programs. Our analysis was based on an empirical research conducted in a major Romanian faculty in the field: Faculty of Economics and Business Administration of Cluj-Napoca. The research was carried out by means of the survey method using quota sampling. Findings have revealed a significant positive contribution of the assessed factors to the increase of the quality of educational process. Also the factors that characterize the instructional process are correlated. The results revealed students concern to acquire practical knowledge. There is also a significant difference between students' expectations and students satisfaction regarding the quality of the content of teaching activity. Unfortunately, in case of all factors the performance of

    Teachers should have pedagogical, personality, social, and professional competency. stated that performance appraisal has several benefits, namely for the implementation of reward and punishment system, provision of feedback for teachers to develop their competencies, identification of training needs, and diagnosis of problems. According to performance is one's work result or success rate as a whole over a certain period of time in performing tasks compared to various possibilities, such as work standards, targets or criteria which have been predetermined and agreed. One's performance is based on daily tasks and responsibilities assigned to him/her. The racial differences in personality are largely due to different environmental influences, where people of different races have progressed for generations. Vocational high school teachers have a low pedagogic and professional performance. The factors that influence performance, according to the partner-lawyer model proposed, are expectations about rewards, encouragements, abilities, needs and traits, perceptions of tasks, internal and external rewards, perceptions of reward levels and job satisfaction. This study used a survey method to collect data or information about a large population using relatively small samples. The population of this research was vocational high school teachers. Data analysis techniques used the Regression Analysis with the assistance of SPSS. The results of teacher performance are as follows: 1) the pedagogic performance was relatively good; 2) professional performance was relatively good, and the overall performance of vocational high school teachers was still less effective and efficient; 3) the teachers' work environment was 42.5234%; and 4) there was no correlation between work environment and teacher performance, meaning that the work environment (conditions of physical work environment, psychological work environment, and non-physical work environment) does not positively support the

    Vogler, Kenneth E.

    The purpose of this study was to determine if the public release of student results on high-stakes, state-mandated performance assessments influence instructional practices, and if so in what manner. The research focused on changes in teachers' instructional practices and factors that may have influenced such changes since the public release of high-stakes, state-mandated student performance assessment scores. The data for this study were obtained from a 54-question survey instrument given to a stratified random sample of teachers teaching at least one section of 10th grade English, mathematics, or science in an academic public high school within Massachusetts. Two hundred and fifty-seven (257) teachers, or 62% of the total sample, completed the survey instrument. An analysis of the data found that teachers are making changes in their instructional practices. The data show notable increases in the use of open-response questions, creative/critical thinking questions, problem-solving activities, use of rubrics or scoring guides, writing assignments, and inquiry/investigation. Teachers also have decreased the use of multiple-choice and true-false questions, textbook-based assignments, and lecturing. Also, the data show that teachers felt that changes made in their instructional practices were most influenced by an "interest in helping my students attain MCAS assessment scores that will allow them to graduate high school" and by an "interest in helping my school improve student (MCAS) assessment scores," Finally, mathematics teachers and teachers with 13--19 years of experience report making significantly more changes than did others. It may be interpreted from the data that the use of state-mandated student performance assessments and the high-stakes attached to this type of testing program contributed to changes in teachers' instructional practices. The changes in teachers' instructional practices have included increases in the use of instructional practices deemed

    Previous studies have shown that individuals diagnosed with OCD tend to rely on explicit processing while performing implicit learning tasks. We sought to investigate whether individuals with OCD are capable of implicit learning, but would demonstrate improved performance when explicit processing strategies are enhanced. Twenty-four participants with OCD and 24 non-psychiatric control (NPC) participants performed an implicit learning task in which they responded to a single target stimulus that successively appears at one of four locations according to an underlying sequence. We manipulated the learning strategy by informing half of the participants that the target stimulus location was determined by an underlying sequence, which they should identify (intentional learning). The other half of the participants was not informed of the existence of the underlying sequence, and was expected to learn the sequence implicitly (standard learning). We predicted that OCD participants will exhibit inferior performance compared to NPC participants in the standard learning condition, and that intentional learning instructions would impair the performance of NPC participants, but enhance the performance of OCD participants. The results supported these predictions and suggest that individuals with OCD prefer controlled to automatic processing. We discuss the implications of this conclusion to our understanding of OCD.

    The future poultry nutritionist, veterinarian, and husbandryman will have many new regulatory requirements and consumer preferences to navigate in addition to their normal responsibility of raising birds in a cost-efficient and wholesome manner. New challenges include changes to antibiotic use, increased food safety regulations, and more concern over how birds are raised and how to dispose of poultry house waste. All of these new programs and new regulations will alter how we have been raising birds for the last 60 years since the inception of the integrated poultry industry. The most significant change may be the voluntary or regulatory withdrawal of the use of antibiotics in poultry production. In North America, this withdrawal of antibiotic use includes removal of in-ovo antibiotics, performance-improving antibiotics or antibiotic growth promotors (AGP), and the polyether ionophore antibiotics (ionophore anticoccidials).The removal of antibiotics in poultry production may result in welfare concerns due to elevated mortality and less efficient feed conversion, resulting in greater environmental impacts from increased manure production and more use of grain per unit of meat produced. There also may be concerns with greater intestinal disease in the birds resulting in increased numbers of foodborne illness-causing bacteria such as Salmonella sp. or Campylobacter sp. on the carcass. A major impact will be the disease necrotic enteritis (NE). This review will focus on the pathophysiology of NE, the management of the disease, and the additional effects on growth rate, feed efficiency, and body weight that may be associated with NE.

    2006-08-01

    Fiber sensor technologies are overviewed. Since the early 1970s, this field has been developed, on the basis of the same devices and photonic principles as fiber communication technologies. Besides simple configurations, in which the fiber acts only as a data transmission line, sophisticated configurations have also been developed, in which the fiber is used as a device to realize unique sensing mechanisms. The fiber optic gyroscope (FOG) is a good example, and has been developed as an absolute rotation sensor used, for example, for navigation and/or attitude control applications. Compared with traditional spinning-mass gyroscopes, the FOG has advantages, such as a short warming-up time, a light weight, and easy handling. A Japanese satellite, which was launched in August 2005 with a mission to observe the aurora, is controlled with a FOG. The FOG has also been used in consumer applications, such as the camera stabilizer, radio-controlled (RC) helicopter navigation, and the control of humanoid robots. Recently, distributed and multiplexed sensing schemes, in particular, have been studied and developed, in which a long fiber acts like a “nerve” for feeling the strain and/or the temperature distribution along the fiber. Performances of artificial nerve systems have markedly improved within the last couple of years, in spatial resolution and measurement speed. By embedding the “fiber-optic nerve system” in aircraft wings, bridges and tall buildings, these materials and structures can sense damage to prevent disasters.

    Many relatively small electrostatic precipitators (ESP`s) exist which collect fly ash at remarkably high efficiencies and have been tested consistently at correspondingly high migration velocities. But the majority of the world`s coal supplies produce ashes which are collected at much lower migration velocities for a given efficiency and therefore require correspondingly large specific collection areas to achieve acceptable results. Early trials of flue gas conditioning (FGC) showed benefits in maximizing ESP performance and minimizing expense which justified continued experimentation. Trials of several dozen ways of doing it wrong eventually developed a set of reliable rules for doing it right. One result is that the use of sulfur trioxide (SO{sub 3}) for adjustment of the resistivity of fly ash from low sulfur coal has been widely applied and has become an automatically accepted part of the option of burning low sulfur coal for compliance with the Clean Air Act of l990 in the U.S.A. Currently, over 100,000 MW of generating capacity is using FGC, and it is estimated that approximately 45,800 MW will utilize coal-switching with FGC for Clean Air Act emission compliance. Guarantees that this equipment will be available to operate at least 98 percent of the time it is called upon are routinely fulfilled.

    Kerr, Rebecca

    The purpose of this descriptive quantitative and basic qualitative study was to examine fifth and eighth grade science teachers' responses, perceptions of the role of technology in the classroom, and how they felt that computer applications, tools, and the Internet influence student understanding. The purposeful sample included survey and interview responses from fifth grade and eighth grade general and physical science teachers. Even though they may not be generalizable to other teachers or classrooms due to a low response rate, findings from this study indicated teachers with fewer years of teaching science had a higher level of computer use but less computer access, especially for students, in the classroom. Furthermore, teachers' choice of professional development moderated the relationship between the level of school performance and teachers' knowledge/skills, with the most positive relationship being with workshops that occurred outside of the school. Eighteen interviews revealed that teachers perceived the role of technology in classroom instruction mainly as teacher-centered and supplemental, rather than student-centered activities.

    2015-01-01

    Introduction. Time-under-tension (TUT) reflects time under load during strength training and is a proxy of the total exercise dose during strength training. The purpose of this study was to investigate if young participants are able to reproduce TUT and exercise form after two weeks of unsupervised exercises. Material and Methods. The study was an assessor-blinded intervention study with 29 participants. After an initial instruction, all participants were instructed to perform two weeks of home-based unsupervised shoulder abduction exercises three times per week with an elastic exercise band. The participants were instructed in performing an exercise with a predefined TUT (3 s concentric; 2 s isometric; 3 s eccentric; 2 s break) corresponding to a total of 240 s of TUT during three sets of 10 repetitions. After completing two weeks of unsupervised home exercises, they returned for a follow-up assessment of TUT and exercise form while performing the shoulder abduction exercise. A stretch sensor attached to the elastic band was used to measure TUT at baseline and follow-up. A physiotherapist used a pre-defined clinical observation protocol to determine if participants used the correct exercise form. Results. Fourteen of the 29 participants trained with the instructed TUT at follow-up (predefined target: 240 s ±8%). Thirteen of the 29 participants performed the shoulder abduction exercise with a correct exercise form. Seven of the 29 participants trained with the instructed TUT and exercise form at follow-up. Conclusion. The majority of participants did not use the instructed TUT and exercise form at follow-up after two weeks of unsupervised exercises. These findings emphasize the importance of clear and specific home exercise instructions if participants are to follow the given exercise prescription regarding TUT and exercise form as too many or too few exercise stimuli in relation to the initially prescribed amount of exercise most likely will provide a

    Mack, Ana C.

    This study examined differences in academic performance and self-regulated learning based on levels of student participation in Supplemental Instruction (SI) sessions in two introductory undergraduate biology and chemistry courses offered at University of Central Florida in the Spring 2006 semester. The sample consisted of 282 students enrolled in the biology class and 451 students enrolled in chemistry. Academic performance was measured using students' final course grades and rates of withdrawal from the courses. The self-regulated learning constructs of motivation, cognition, metacognition, and resource management were measured using the Motivated Strategies for Learning Questionnaire (MSLQ). Relationships between students' gender and ethnic background and levels of SI participation were also analyzed in this research. Findings in both biology and chemistry courses revealed a statistically significant decrease in student motivation from beginning to end of semester. In chemistry, frequent SI participants also showed statistically significantly higher levels of motivation at the end of the semester than occasional and non-SI participants. There were no statistically significant gains in cognitive, metacognitive, and resource management strategies from beginning to end of semester. However, statistically significant differences in resource management were observed at the end of the semester among SI attendance groups in both courses. Students in the high SI attendance group were more likely to use learning resources than those who did not participate regularly or did not participate at all. Statistically significant differences in academic performance based on students' SI participation were found in both biology and chemistry courses. Frequent SI participants had significantly higher final percentage grades and were more likely to receive grades of A, B, or C, than those who either did not attend SI regularly of did not participate at all. They were also less

    Full Text Available On-The-Job Training, developed as direct instruction, is one of the earliest forms of training. This method is still widely in use today because it requires only a person who knows how to do the task, and the tools the person uses to do the task. This paper is intended to be a study of the methods used in education in Knowledge Society, with more specific aspects in training the trainers; as a result of this approach, it promotes scaffolding in assisted instruction as a reflection of the digital age for the learning process. Training the trainers in old environment with default techniques and designing the learning process in assisted instruction, as an application of the Vygotskian concept of the zone of proximal development (ZPD to the area of computer literacy for the younger users, generate diversity in educational communities and requires standards for technology infrastructure, standards for the content, developed as a concepts map, and applications for personalized in-struction, based on ZPD theory.

    Dyson, Hilarie

    2008-10-01

    The purpose of the study was to identify structures and systems implemented in a high-performing high-poverty urban school to promote high academic achievement among students of color. The researcher used a sociocultural theoretical framework to examine the influence of culture on the structures and systems that increased performance by African American and Hispanic students. Four research questions guided the study: (1) What are the trends and patterns of student performance among students of color? (2) What are the organizational structures and systems that are perceived to contribute to high student performance in high-poverty urban schools with high concentrations of students of color? (3) How are the organizational structures and systems implemented to support school-wide effective classroom instruction that promotes student learning? (4) How is the construct of race reflected in the school's structures and systems? Qualitative data were collected through interviews, observations, and artifact collection. A single case study method was employed and collected data were triangulated to capture and explore the rich details of the study. The study focused on a high-performing high-poverty urban elementary school located in southern California. The school population consisted of 99% students of color and 93% were economically disadvantaged. The school was selected for making significant and consistent growth in Academic Performance Index and Adequate Yearly Progress over a 3-year period. The school-wide structures and systems studied were (a) leadership, (b) school climate and culture, (c) standards-based instruction, (d) data-driven decision making, and (e) professional development. Four common themes emerged from the findings: (a) instructional leadership that focused on teaching and learning; (b) high expectations for all students; (c) school-wide focus on student achievement using standards, data, and culturally responsive teaching; and (d) positive

  20. Today's threat and tomorrow's reaction

    2002-01-01

    Full text: The events of September 11 have only confirmed our past nightmares and warnings to industries, agencies, and governments. The threat of even more significant catastrophic attacks, using nuclear materials, was just as real ten years ago, as it is today. In many cases, our vulnerability remains the same as years ago. There is a dire need for all organizations to agree upon threats and vulnerabilities, and to implement appropriate protections, for nuclear materials or other 'means' to achieve an event of mass destruction. All appropriate organizations (industries, agencies, and governments) should be able to define, assess, and recognize international threats and vulnerabilities in the same manner. In complimentary fashion, the organizations should be able to implement safeguards against this consistent generic threat. On an international scale the same threats, and most vulnerabilities, pose high risks to all of these organizations and societies. Indeed, in today's world, the vulnerabilities of one nation may clearly pose great risk to another nation. Once threats and vulnerabilities are consistently recognized, we can begin to approach their mitigation in a more 'universal' fashion by the application of internationally recognized and accepted security measures. The path to recognition of these security measures will require agreement on many diverse issues. However, once there is general agreement, we can then proceed to the acquisition of diverse national and international resources with which to implement the security measures 'universally' to eliminate 'weak-links' in the chain of nuclear materials, on a truly international scale. I would like to discuss: developing a internationally acceptable 'generic' statement of threat, vulnerability assessment process, and security measure; proposing this international statement of threat, vulnerability assessment process, and appropriate security measures to organizations (industries, agencies, and governments

    Extensive research has been conducted in the development of methods to predict the degradation of F-44 in storage. The Low Pressure Reactor (LPR) has greatly enhanced the stability prediction capabilities necessary to make informed decisions concerning aviation fuel in storage. This technique has in the past been primarily used for research purposes. The Naval Air Warfare Center, Aircraft Division, Trenton, NJ, has used this technique successfully to assist the Defense Fuel Supply Center, Cameron Station, Alexandria, VA, in stability assessments of F-44. The High Performance Liquid Chromatography/Electrochemical Detector (HPLC/EC) antioxidant determination technique has also aided in making stability predictions by establishing the amount of inhibitor currently in the product. This paper will address two case studies in which the above new technology was used to insure the rapid detection and diagnosis of today`s field and logistic problems.

  3. Religious Renaissance in China Today

    Directory of Open Access Journals (Sweden)

    Richard Madsen

    2011-01-01

    Full Text Available Since the beginning of the Reform Era in 1979, there has been a rapid growth and development of religious belief and practice in China. A substantial new scholarly literature has been generated in the attempt to document and understand this. This essay identifies the most important contributions to that literature and discusses areas of agreement and controversy across the literature. Along with new data, new paradigms have developed to frame research on Chinese religions. The paradigm derived from C. K. Yang’s classic work in the 1960s came from structural functionalism, which served to unite research in the humanities and social sciences. However, structural functionalism has been abandoned by the new generation of scholars. In the humanities, the most popular paradigm derives from Michel Foucault, but there are also scholars who use neo-Durkheimian and neo-Weberian paradigms. In the social sciences, the dominant paradigms tend to focus on state-society relations. None of these paradigms fully captures the complexity of the transformations happening in China. We recommend greater dialogue between the humanities and social sciences in search of more adequate theoretical frameworks for understanding Chinese religions today.

  4. The Coolness of Capitalism Today

    Directory of Open Access Journals (Sweden)

    Jim McGuigan

    2012-05-01

    Full Text Available This paper is about the reconciliation of cultural analysis with political economy in Marxist-inspired research on communications. It traces how these two traditions became separated with the development of a one-dimensional and consumerist cultural studies, on the one-hand, and a more classically Marxist political economy of communications, on the other hand, that was accused of holding a simplistic and erroneous concept of ideology. The paper defends a conception of ideology as distorted communication motivated by unequal power relations and sketches a multidimensional mode of cultural analysis that takes account of the moments of production, consumption and textual meaning in the circulation of communications and culture. In accordance with this framework of analysis, the cool-capitalism thesis is outlined and illustrated with reference to Apple, the ‘cool’ corporation. And, the all-purpose mobile communication device is selected as a key and urgent focus of attention for research on commodity fetishism and labour exploitation on a global scale today.

    2010-01-01

    Radioactive hydrogen isotope, tritium is one of the radionuclides which is the most released in the environment during the normal operation of nuclear facilities. The increase of nuclear activities and the development of future generations of reactors, like the EPR and ITER, would lead to a significant increase of tritium effluents in the atmosphere and in the natural waters, thus raising many worries and questions. Aware about the importance of this question, the national association of local information commissions (ANCLI) wished to make a status of the existing knowledge concerning tritium and organized in 2008 a colloquium at Orsay (France) with an inquiring approach. The scientific committee of the ANCLI, renowned for its expertise skills, mobilized several nuclear specialists to carry out this thought. This book represents a comprehensive synthesis of today's knowledge about tritium, about its management and about its impact on the environment and on human health. Based on recent scientific data and on precise examples, it treats of the overall questions raised by this radionuclide: 1 - tritium properties and different sources (natural and anthropic), 2 - the problem of tritiated wastes management; 3 - the bio-availability and bio-kinetics of the different tritium species; 4 - the tritium labelling of environments; 5 - tritium measurement and modeling of its environmental circulation; 6 - tritium radio-toxicity and its biological and health impacts; 7 - the different French and/or international regulations concerning tritium.

  7. Artificial insemination in pigs today.

    Knox, R V

    2016-01-01

    Use of artificial insemination (AI) for breeding pigs has been instrumental for facilitating global improvements in fertility, genetics, labor, and herd health. The establishment of AI centers for management of boars and production of semen has allowed for selection of boars for fertility and sperm production using in vitro and in vivo measures. Today, boars can be managed for production of 20 to 40 traditional AI doses containing 2.5 to 3.0 billion motile sperm in 75 to 100 mL of extender or 40 to 60 doses with 1.5 to 2.0 billion sperm in similar or reduced volumes for use in cervical or intrauterine AI. Regardless of the sperm dose, in liquid form, extenders are designed to sustain sperm fertility for 3 to 7 days. On farm, AI is the predominant form for commercial sow breeding and relies on manual detection of estrus with sows receiving two cervical or two intrauterine inseminations of the traditional or low sperm doses on each day detected in standing estrus. New approaches for increasing rates of genetic improvement through use of AI are aimed at methods to continue to lower the number of sperm in an AI dose and reducing the number of inseminations through use of a single, fixed-time AI after ovulation induction. Both approaches allow greater selection pressure for economically important swine traits in the sires and help extend the genetic advantages through AI on to more production farms.

    Runge, Alan Paul

    1997-10-01

    A traditional undergraduate physics course on mathematical methods has been redesigned to incorporate the use of Maplesp{sc {TM}}, a computer algebra program, during all aspects of the course. Topics covered were: complex number theory; series approximations; matrix theory; partial differentiation; vector algebra; and vector calculus. Five undergraduate students were enrolled, from sophomore to senior in academic class standing. A qualitative case study methodology was used to describe the changes in the course design resulting from the incorporation of Maplesp{sc {TM}} and their impact on the instruction of the course, and to determine the effects on the students' learning and development of problem solving skills in physics using Maplesp{sc {TM}} as a problem solving tool. The impact of using Maplesp{sc {TM}} on the number and types of interactions is presented. The entire semester long course was included in this study. Each class session is described in detail. Examples of the Maplesp{sc {TM}} materials used are given. The use of the Maplesp{sc {TM}} program was allowed on all homework and exams with each student having their own computer during class. Constraints were made so that the assessment emphasis remained on the mathematics and the conceptual understanding of the problem solving methods. All of the students demonstrated some level of proficiency in using Maplesp{TM} to solve the assigned problems. Strategies for effectively using Maplesp{TM} were presented and were individualized by the students. The students reported positive and negative impacts of using Maplesp{sc {TM}}. All of the students satisfactorily completed the course requirements, receiving final course grades from B to A+. All of them continued to voluntarily use Maplesp{sc {TM}} during the following semester. Instructional methods used included various lecture techniques without Maplesp{sc {TM}} assistance, lectures and demonstrations using only Maplesp{sc {TM}}, and student tasks

Esta cuestión de Hitler en la actualidad posee diversos problemas históricos que están íntimamente conectados con otros morales. En este trabajo, sin embargo, pretendo concentrarme primordialmente en su dimensión histórica. A la luz del sorprendente ascenso de Hitler en la moderna conciencia histórica, esto puede llevarnos a la siguiente pregunta: ¿No hemos otorgado al dictador nazi un poder aún mayor que cuando estaba vivo y comandando sus divisiones de la Wehrmacht en el punto culminante de sus conquistas?___________________ABSTRACT:By the end of the twentieth century, it can be said, Hitler was more alive and prominent than at the height of his power a half-century before. How did Hitler become this way? Isn’t he dead? How can he become so prominent more than half a century after his death? The issue of Hitler today poses several historical problems that are deeply moral problems as well. In this work, however, I intend to concentrate primarily on their historical dimension. In light of Hitler’s astonishing rise in modern historical consciousness, this leads to the inevitable question: Have we not granted to Hitler a far greater power over us than ever he had when he was alive and commanding his Wehrmacht divisions at the farthest extent of his conquests?

    Mazour, T.J.; Ball, F.M.

    1985-11-01

    This report provides information to nuclear power plant training managers and their staffs concerning the job performance requirements of instructional personnel to implement prformance-based training programs (also referred to as the Systems Approach Training). The information presented in this report is a compilation of information and lessons learned in the nuclear power industry and in other industries using performance-based training programs. The job performance requirements in this report are presented as instructional skills objectives. The process used to develop the instructional skills objectives is described. Each objective includes an Instructional Skills Statement describing the behavior that is expected and an Instructional Skills Standard describing the skills/knowledge that the individual should possess in order to have achieved mastery. The instructional skills objectives are organized according to the essential elements of the Systems Approach to Training and are cross-referenced to three categories of instructional personnel: developers of instruction, instructors, and instructional managers/supervisors. Use of the instructional skills objectives is demonstrated for reviewing instructional staff training and qualification programs, developing criterion-tests, and reviewing the performance and work products of individual staff members. 22 refs

    The purpose of this study was to compare the effectiveness of an interactive, multimedia CD-ROM with traditional methods of teaching the skill of performing a 12-lead ECG. A randomized pre/posttest experimental design was used. Seventy-seven baccalaureate nursing students in a required, senior-level critical-care course at a large midwestern university were recruited for the study. Two teaching methods were compared. The traditional method included a self-study module, a brief lecture and demonstration by an instructor, and hands-on experience using a plastic manikin and a real 12-lead ECG machine in the learning laboratory. The second method covered the same content using an interactive, multimedia CD-ROM embedded with virtual reality and supplemented with a self-study module. There were no significant (p method, or perception of self-efficacy in performing the skill. Overall results indicated that both groups were satisfied with their instructional method and were similar in their ability to demonstrate the skill correctly on a live, simulated patient. This evaluation study is a beginning step to assess new and potentially more cost-effective teaching methods and their effects on student learning outcomes and behaviors, including the transfer of skill acquisition via a computer simulation to a real patient.

  12. Botulinum toxin: yesterday, today, tomorrow

    Directory of Open Access Journals (Sweden)

    A. R. Artemenko

    2013-01-01

    Full Text Available Botulinum toxin (BoNT is a bacterial neurotoxin presented with seven serotypes that inhibit neurotransmitter release from nerve endings. The serotypes of BoNT are antigenically dissimilar, act via different, but interconnected mechanisms, and are not interchangeable. The activity of BoNT is associated with impaired neuroexocytosis occurring in several steps: from the binding of BoNT to its specific receptor on the axon terminal membrane to the proteolytic enzymatic cleavage of SNARE substrate. The effect of BoNT is considered to be restricted to the peripheral nervous system, but when given in particularly high doses, it has been recently shown to affect individual brain structures. In addition, by modulating peripheral afferentation, BoNT may influence the excitability of central neuronal structures at both spinal and cortical levels. Only BoNT serotypes A and B are used in clinical practice and aesthetic medicine. The type A has gained the widest acceptance as a therapeutic agent for more than 100 abnormalities manifesting themselves as muscular hyperactivity, hyperfunction of endocrine gland, and chronic pain. The effect of BoNT preparations shows itself 2-5 days after injection, lasts 3 months or more, and gradually decreases with as a result of pharmacokinetic and intracellular reparative processes. Biotechnology advances and potentialities allow purposefully modification of the protein molecular structure of BoNT, which expands the use and efficiency of performed therapy with neurotoxins. Recombinant technologies provide a combination of major therapeutic properties of each used BoNT serotype and expand indications for recombinant chimeric toxins.

    In all OECD countries, digital media and connectedness are integral to the lives of todays learners. It is often claimed that these learners are ""new millennium learners"", or ""digital natives"", who have different expectations about education. This book contributes to the debate about the effects of technology attachment and connectedness on todays learners, and their expectations about teaching. The book sets out to answer the following questions: Can the claim that todays students are ""new millenium learners"" or ""digital natives be sustained empirically? Is there consistent research evidence demonstrating the effects of technology on cognitive development, social values, and learning expectations? What are the implications for educational policy and practice?

    Providing children with organizational strategy instruction on the Rey Osterrieth Complex Figure (ROCF) has previously been found to improve organizational and accuracy performance on this task. It is unknown whether strategy instruction on the ROCF would also transfer to performance improvement on copying and the recall of another complex figure. Participants were 98 typically developing children (aged 9.5-12.6 years, M = 10.6). Children completed the ROCF (copy and recall) as a pretest. Approximately a month later, they were randomized to complete the ROCF with strategy instruction in the form of a stepwise administration of the ROCF or again in the standard format. All children then copied and recalled the Modified Taylor Complex Figure (MTCF). All productions were assessed in terms of organization, accuracy and completion time. Organization scores for the MTCF did not differ for the two groups for the copy production, but did differ for the recall production, indicating transfer. Accuracy and completion times did not differ between groups. Performance on all measures, except copy accuracy, improved between pretest ROCF and posttest MTCF production for both groups, suggesting practice effects. Findings indicate that transfer of strategy instruction from one complex figure to another is only present for organization of recalled information. The increase in RCF-OSS scores did not lead to a higher accuracy or a faster copy or recall.

    Saun, Tomas J; Odorizzi, Scott; Yeung, Celine; Johnson, Marjorie; Bandiera, Glen; Dev, Shelly P

    Online medical education resources are becoming an increasingly used modality and many studies have demonstrated their efficacy in procedural instruction. This study sought to determine whether a standardized online procedural video is as effective as a standard recorded didactic teaching session for chest tube insertion. A randomized control trial was conducted. Participants were taught how to insert a chest tube with either a recorded didactic teaching session, or a New England Journal of Medicine (NEJM) video. Participants filled out a questionnaire before and after performing the procedure on a cadaver, which was filmed and assessed by 2 blinded evaluators using a standardized tool. Western University, London, Ontario. Level of clinical care: institutional. A total of 30 fourth-year medical students from 2 graduating classes at the Schulich School of Medicine & Dentistry were screened for eligibility. Two students did not complete the study and were excluded. There were 13 students in the NEJM group, and 15 students in the didactic group. The NEJM group׳s average score was 45.2% (±9.56) on the prequestionnaire, 67.7% (±12.9) for the procedure, and 60.1% (±7.65) on the postquestionnaire. The didactic group׳s average score was 42.8% (±10.9) on the prequestionnaire, 73.7% (±9.90) for the procedure, and 46.5% (±7.46) on the postquestionnaire. There was no difference between the groups on the prequestionnaire (Δ + 2.4%; 95% CI: -5.16 to 9.99), or the procedure (Δ -6.0%; 95% CI: -14.6 to 2.65). The NEJM group had better scores on the postquestionnaire (Δ + 11.15%; 95% CI: 3.74-18.6). The NEJM video was as effective as video-recorded didactic training for teaching the knowledge and technical skills essential for chest tube insertion. Participants expressed high satisfaction with this modality. It may prove to be a helpful adjunct to standard instruction on the topic. Copyright © 2017 Association of Program Directors in Surgery.

Purpose: We conducted a randomized controlled trial to investigate the differential learning outcomes of the separate steps of Peyton’s four-step approach. Methods: Volunteer medical students were randomly assigned to four different groups. Step-1 group received Peyton’s Step 1, Step-2 group received Peyton’s Steps 1 and 2, Step-3 group received Peyton’s Steps 1, 2, and 3, and Step-3mod group received Peyton’s Steps 1 and 2, followed by a repetition of Step 2. Following the training, the first independent performance of a central venous catheter (CVC insertion using a manikin was video-recorded and scored by independent video assessors using binary checklists. The day after the training, memory performance during delayed recall was assessed with an incidental free recall test. Results: A total of 97 participants agreed to participate in the trial. There were no statistically significant group differences with regard to age, sex, completed education in a medical profession, completed medical clerkships, preliminary memory tests, or self-efficacy ratings. Regarding checklist ratings, Step-2 group showed a superior first independent performance of CVC placement compared to Step-1 group (P<0.001, and Step-3 group showed a superior performance to Step-2 group (P<0.009, while Step-2 group and Step-3mod group did not differ (P=0.055.

  20. Effective instruction for English learners.

    Science.gov (United States)

    Calderón, Margarita; Slavin, Robert; Sánchez, Marta

    2011-01-01

    The fastest-growing student population in U.S. schools today is children of immigrants, half of whom do not speak English fluently and are thus labeled English learners. Although the federal government requires school districts to provide services to English learners, it offers states no policies to follow in identifying, assessing, placing, or instructing them. Margarita Calderón, Robert Slavin, and Marta Sánchez identify the elements of effective instruction and review a variety of successful program models. During 2007-08, more than 5.3 million English learners made up 10.6 percent of the nation's K-12 public school enrollment. Wide and persistent achievement disparities between these English learners and English-proficient students show clearly, say the authors, that schools must address the language, literacy, and academic needs of English learners more effectively. Researchers have fiercely debated the merits of bilingual and English-only reading instruction. In elementary schools, English learners commonly receive thirty minutes of English as a Second Language (ESL) instruction but attend general education classes for the rest of the day, usually with teachers who are unprepared to teach them. Though English learners have strikingly diverse levels of skills, in high school they are typically lumped together, with one teacher to address their widely varying needs. These in-school factors contribute to the achievement disparities. Based on the studies presented here, Calderón, Slavin, and Sánchez assert that the quality of instruction is what matters most in educating English learners. They highlight comprehensive reform models, as well as individual components of these models: school structures and leadership; language and literacy instruction; integration of language, literacy, and content instruction in secondary schools; cooperative learning; professional development; parent and family support teams; tutoring; and monitoring implementation and outcomes

    Full Text Available In this contribution, Slavoj Žižek takes the occasion of Marx’s bicentenary for reflecting on the prospects of radical change today. First, it is shown that under Stalinism, Lenin’s works were quoted out of context in an arbitrary way in order to legitimise arbitrary political measures. Marxism thereby became an ideology that justified brutal subjective interventions. Second, this contribution poses the question of the revolutionary subject and democracy today. It stresses the role of both contingency and strategy in revolutions. In political assemblages taking place on public squares, the inert mass of ordinary people is transubstantiated into a politically engaged united force. The basic political problem today is how to best reconfigure democracy. Third, this contribution analyses the “interesting times” we live in. These are times that feature multiple crises, right-wing populism à la Donald Trump and Marine Le Pen, the lower classes’ opposition to immigration, and the refugee crisis. Questions about human rights and their violation and about radical change need to be asked in this context.

  14. "Children are from heaven" or how today children respect adults

    Directory of Open Access Journals (Sweden)

    2007-06-01

    Full Text Available The starting point of the text is a returning to the patriarchal, which is not simply the one that we are witnessing today, in the time of so-called postmodern, postpatriarchal society in its (until now last form. It is a matter of returning to rules, of which the basic premise is that adults are subjects (transcendences, freedoms, activities and children are subjects that are objects for adults (imanences, non-freedoms, pasivities, but which notwithstanding differ from the oldfashioned rules from the past. We attempted to explain this returning, following the example of rules offered by the book Children Are From Heaven – a selfhelp book, published at the end of the nineties of the 20th century, which immediately became the world's bestseller. In addition, our aim was to answer the following questions: What has happened with rules of civilization and good manners, regulating the relations between children and adults today? How have they changed and what has happened with children's or adults's relation to these rules or their performings? How has this relation changed? Considering the mentioned basic premise which implies that children respect adults, we also tried to answer the question: What has happened with the respect, or, how do children respect adults today? Disscussion is presented in the framework of lacanian psychoanalysis.

  16. Instructable autonomous agents. Ph.D. Thesis

    Science.gov (United States)

    Huffman, Scott Bradley

    1994-01-01

    In contrast to current intelligent systems, which must be laboriously programmed for each task they are meant to perform, instructable agents can be taught new tasks and associated knowledge. This thesis presents a general theory of learning from tutorial instruction and its use to produce an instructable agent. Tutorial instruction is a particularly powerful form of instruction, because it allows the instructor to communicate whatever kind of knowledge a student needs at whatever point it is needed. To exploit this broad flexibility, however, a tutorable agent must support a full range of interaction with its instructor to learn a full range of knowledge. Thus, unlike most machine learning tasks, which target deep learning of a single kind of knowledge from a single kind of input, tutorability requires a breadth of learning from a broad range of instructional interactions. The theory of learning from tutorial instruction presented here has two parts. First, a computational model of an intelligent agent, the problem space computational model, indicates the types of knowledge that determine an agent's performance, and thus, that should be acquirable via instruction. Second, a learning technique, called situated explanation specifies how the agent learns general knowledge from instruction. The theory is embodied by an implemented agent, Instructo-Soar, built within the Soar architecture. Instructo-Soar is able to learn hierarchies of completely new tasks, to extend task knowledge to apply in new situations, and in fact to acquire every type of knowledge it uses during task performance - control knowledge, knowledge of operators' effects, state inferences, etc. - from interactive natural language instructions. This variety of learning occurs by applying the situated explanation technique to a variety of instructional interactions involving a variety of types of instructions (commands, statements, conditionals, etc.). By taking seriously the requirements of flexible

  1. Corrosion issues in nuclear industry today

    International Nuclear Information System (INIS)

    Cattant, F.; Crusset, D.; Feron, D.

    2008-01-01

    In the context of global warming, nuclear energy is a carbon-free source of power and so is a meaningful option for energy production without CO 2 emissions. Currently, there are more than 440 commercial nuclear reactors, accounting for about 15% of electric power generation in the world, and there has not been a major accident in over 20 years. The world's fleet of nuclear power plants is, on average, more than 20 years old. Even though the design life of a nuclear power plant is typically 30 or 40 years, it is quite feasible that many nuclear power plants will be able to operate for longer than this. The re-emergence of nuclear power today is founded on the present generation of nuclear reactors meeting the demands of extended service life, ensuring the cost competitiveness of nuclear power and matching enhanced safety requirements. Nuclear power plant engineers should be able to demonstrate such integrity and reliability of their system materials and components as to enable nuclear power plants to operate beyond their initial design life. Effective waste management is another challenge for sustainable nuclear energy today; more precisely, a solution is needed for the management of high-level and long-lived intermediate-level radioactive waste over the very long term. Most nuclear countries are currently gathering the data needed to assess the feasibility of a deep geological waste repository, including the prediction of the behaviour of materials over several thousands of years. The extended service life of nuclear power plants and the need for permanent disposal for nuclear waste are today's key issues in the nuclear industry. We focus here on the major role that corrosion plays in these two factors, and on the French approaches to these two issues. (authors)

    2013-11-01

    Aromatics are the essential building blocks for some of the largest petrochemical products in today's use. To the vast majority they are consumed to produce intermediates for polymer products and, hence, contribute to our modern lifestyle. Their growth rates are expected to be in line with GDP growth in future. This contrasts the significantly lower growth rates of the primary sources for aromatics - fuel processing and steam cracking of naphtha fractions. A supply gap can be expected to open up in future for which creative solutions will be required. (orig.)

    Graphing is socially significant for behavior analysts; however, graphing can be difficult to learn. Video modeling (VM) may be a useful instructional method but lacks evidence for effective teaching of computer skills. A between-groups design compared the effects of VM, text-based instruction, and no instruction on graphing performance. Participants who used VM constructed graphs significantly faster and with fewer errors than those who used text-based instruction or no instruction. Implications for instruction are discussed. © Society for the Experimental Analysis of Behavior.

    Canonico, D.A.

    1995-01-01

    Since its modest beginning as a single volume in 1914 the ASME Code, or some of its parts, is recognized today in 48 of the United States and all providence's of Canada. The ASME Code today is composed of 25 books including two Code Case books. These books cover the new construction of boilers and pressure vessels and the new construction and In-Service-Inspection of Nuclear Power Plant components. The ASME accredits all manufacturers of boilers and pressure vessels built to the ASME Code. There are approximately 7650 symbol stamps issued throughout the world. Over 23% of the symbol stamps have been issued outside the USA and Canada. The challenge to the ASME Code is to be accepted as the world standard for pressure boundary components. There are activities underway to achieve that goal. The ASME Code is being revised to make it a more friendly document to entities outside of North America. To achieve that end there are specific tasks underway which are described here

  13. Gilson, Krapiec and Christian Philosophy Today

    Pawel Tarasiewicz

    2015-12-01

    Full Text Available The author undertakes an attempt to answer the following question: is Christian philosophy possible today? The question seems to be of great importance due to the fact that what Christians who try to do philosophy usually encounter is bitter criticism which comes to them from two sides at once: that of academy and that of the Church. In short, for academy their philosophy is too Christian, and for the Church it is too academic. Being indebted to the insights of Étienne Gilson and Mieczyslaw A. Krapiec (the original Polish spelling: Mieczysław Albert Krąpiec, pronounced: myechisuaf albert krompyetz, the author comes to the conclusion thatChristian philosophy is possible today only if: 1 it isnot identified with the art of persuasion, as its final end lies in gaining understanding rather than being convincing, 2 itis the work of a Christian, and 3 it has thereal world as its object and metaphysics as its method. ForChristian philosophy—which in essence consists indoing philosophy by Christians in order to get morerational understanding of their religious faith—shouldbe identified with theperfection of the intellect achieved by practicingthe classical philosophy of being.

  17. Teaching medical anatomy: what is the role of imaging today?

    Science.gov (United States)

    Grignon, Bruno; Oldrini, Guillaume; Walter, Frédéric

    2016-03-01

    Medical anatomy instruction has been an important issue of debate for many years and imaging anatomy has become an increasingly important component in the field, the role of which has not yet been clearly defined. The aim of the paper was to assess the current deployment of medical imaging in the teaching of anatomy by means of a review of the literature. A systematic search was performed using the electronic database PubMed, ScienceDirect and various publisher databases, with combinations of the relevant MeSH terms. A manual research was added. In most academic curricula, imaging anatomy has been integrated as a part of anatomical education, taught using a very wide variety of strategies. Considerable variation in the time allocation, content and delivery of medical imaging in teaching human anatomy was identified. Given this considerable variation, an objective assessment remains quite difficult. In most publications, students' perceptions regarding anatomical courses including imaging anatomy were investigated by means of questionnaires and, regardless of the method of teaching, it was globally concluded that imaging anatomy enhanced the quality and efficiency of instruction in human anatomy. More objective evaluation based on an increase in students' performance on course examinations or on specific tests performed before and after teaching sessions showed positive results in numerous cases, while mixed results were also indicated by other studies. A relative standardization could be useful in improving the teaching of imaging anatomy, to facilitate its assessment and reinforce its effectiveness.

    Mahabaduge, Hasitha; Haslam, Jeanne

    Supplemental instruction utilizes peer-assisted study sessions to provide review sessions on course material and an opportunity to discuss and work out problems. The impact of supplemental instruction on student performance is well researched and used in a large number of universities around the world due to its proven success. However, the impact of the student leader who plays a significant role in this model is rarely discussed in the literature. We present a case study on the impact of student leader on the success of supplemental instruction model. This case study was done for an Introductory Physics course correlating student performance and the supplemental instruction sessions they attended. Further analysis revealed that the academic performance and work ethics of the student leader has a significant impact on the success of the supplemental instruction model. Important factors to consider when selecting a student leader, the challenges and possible remedies will also be discussed.

    Full Text Available Ancient Azerbaijanian music was found after archelogical excavations. In the first literature The Book of Dede Korkut, then in Nizami's and Fuzuli's literal works a vast of information could be found about the Medieval Age music. The first phase of Azerbaijanian musical history contains arts of bards, laters phases contains classical modes. The researches of Azerbaijanian modes extend to the Medieval Age. The expand of 19th century European music affected Azerbaijanian culture, too. The early years of 20th century is reckoned as a new rising period in Azerbaijanin music. Uzeyir Hacibeyov composed Leyli and Majnun in that period which was the first opera of the East. Meanwhile, several musical high schools, conservatories, symphony orchestras, national instrumental orchestras, and theatres were established. The smphonic music which was established in 1920's had a major development in between 1940 and 1960. In between 1960 and 1980, younger generation, too, participated in artistic activities, alongside the older generation. In 1988-1994 Armenians invaded Karabagh and commited several genocides which some of the most known are called 20 January and Khojaly genocides. In that period, Azerbaijanian composes divided into three stages as 20 January, Karabagh, and Khojaly. Today, Azerbaijanian music is well known all over the world, while being played in lots of festivals in the whole world.

  8. Introduction: The Continued Importance of Smallholders Today

    Directory of Open Access Journals (Sweden)

    Jacqueline M. Vadjunec

    2016-10-01

    Full Text Available Smallholders remain an important part of human-environment research, particularly in cultural and political ecology, peasant and development studies, and increasingly in land system and sustainability science. This introduction to the edited volume explores land use and livelihood issues among smallholders, in several disciplinary and subfield traditions. Specifically, we provide a short history of smallholder livelihood research in the human-environment tradition. We reflect on why, in an age of rapid globalization, smallholder land use and livelihoods still matter, both for land system science and as a reflection of concerns with inequality and poverty. Key themes that emerge from the papers in this volume include the importance of smallholder farming and land-use practices to questions of environmental sustainability, the dynamic reality of smallholder livelihoods, the challenges of vulnerability and adaptation in contemporary human-environment systems, and the structural and relative nature of the term “smallholder.” Overall these contributions show that smallholder studies are more pertinent than ever, especially in the face of global environmental change. Additionally, we argue that questions of smallholder identity, social difference, and teleconnections provide fertile areas of future research. We conclude that we need to re-envision who the smallholder is today and how this translates into modern human-environment smallholder studies.

    2010-09-01

    As members of professional organizations such as American Society of Primatologists (ASP) and the International Primatological Society (IPS), primatologists must adhere to a set of nonhuman primate-focused principles outlined in resolutions and policy statements on, for example, the ethical treatment of nonhuman primates. Those of us that work in the field must also address issues such as the protection of primate health in the wild and the conservation of wild primate populations. Moreover, we increasingly find ourselves in complex situations where we must balance human and nonhuman primate needs and interests. The selection of commentary pieces in this edition of the American Journal of Primatology originated from presentations given in the symposium, Field Primatology of Today: Navigating the Ethical Landscape, held at the 32nd Annual Meeting of the American Society of Primatologists (ASP) in September 2009. The goals of that symposium and these resulting commentary pieces are threefold: (1) to revive a discussion of key contemporary ethical issues faced by field primatologists, (2) to highlight the need for centrally placed ethical considerations in various facets of our professional lives, particularly research and teaching, and (3) to consider what a comprehensive ethical code that addresses all of these issues might look like.

    Full Text Available The rapid change experienced in the field of Information Technologies makes the informati cs more tangible in daily life. Today, it became possible to encounter with the informatics applications almost all the disciplines. As a matter of course, many informatics applications are put into the practice regarding the sports discipline. Because of the condition that the power of information processing has increased and the studies on wearable technol ogies in addition to the expert system design, augmented reality (AR has become a topic which gains imp ortance in the field of sports. There are many studies that are conducted with the aim of increasing the efficiency of physical activities done in many sports branches, ensuring a more fair management of competitions and providing the opportunity for spectators to watch the competitions in a more comfortable and efficient way. In this study; the information about the current augmented reality practices th at are used in various sports branches has been given and the mobile and interactive augmented reality practices which are possible to be seen in future have been mentioned. In addition, there is an augmented reality practice which is designed with the aim of ensuring that the shoots of sports people who are interested in archery, are more stable and of ensuring that the trainings and exercises are more efficient by stating to the sports people whether he or she is in the right position for shoot which is c alled as T shape seen at the time of releasing the arrow.

    LaDuke, Rebekah D

    2013-01-01

    The purpose of this article was to review the most current published literature on the topics of academic dishonesty, unethical professional practices, and research that studied the correlation between these 2 areas of interest. Literature was retrieved by utilizing key words such as academic dishonesty, cheating, workplace dishonesty, and unethical behavior. Multiple research databases were used and a reference librarian in locating relevant research studies resulting in 16 research articles reviewed and 7 articles referenced within the literature review. Upon completion, it became apparent that nursing educators should be concerned that nursing students found to be academically dishonest today may have a higher incidence of displaying unethical practices as a registered nurse tomorrow. It also became clear that the nursing profession needs to conduct its own research in this field to verify findings discovered by other professions such as engineering, business, and psychology. Finally, recommendations were given on how nursing educators should handle the topic of ethics in nursing programs. Copyright © 2013 Elsevier Inc. All rights reserved.

  12. [Poliomyelitis in Landsteiner's time and today].

    1991-01-01

    At a meeting of the Royal and Imperial Association of Physicians in Vienna on December 18, 1908 Dr. Karl Landsteiner reported on the successful experimental transmission of poliomyelitis from man to ape in a study which he undertook together with Erwin Popper. In a scientific article that was published shortly after the meeting, Landsteiner wrote that "the poliomyelitis virus belongs to the group of filterable micro-organisms". Soon, Landsteiner's results were confirmed by other colleagues. During a congress in Washington 1912 Landsteiner declared that the development of a vaccine against poliomyelitis might prove difficult but was certainly possible in his opinion. It took another 45 years before the first polio vaccine was available (1955 Salk) and another 5 years until the oral vaccine (1960 Sabin) was implemented. The incidence of poliomyelitis decreased dramatically in industrial countries as a result of vaccination. Today, poliomyelitis is still an enormous threat in developing countries. Together with many national and international institutions the WHO fights this situation very hard by means of vaccination campaigns. The incidence of side effects and insufficient reactions is small with both vaccines. New techniques in the field of molecular biology and a good knowledge of the poliovirus make it likely that further improvements on the vaccines which are currently available will take place.

    2005-09-01

    Today, you are about as safe in a U.S. hospital as you would be parachuting off a bridge or a building. But it doesn't have to be that way. Right now, some hospitals are making enormous short-term improvements, with no legislation or market reconfiguration and little or no capital investment. Instead of waiting for sweeping changes in market mechanisms, these institutions are taking an operations approach to patient care. In case after detailed case, the article describes how doctors, nurses, technicians, and managers are radically increasing the effectiveness of patient care and dramatically lowering its cost by applying the same capabilities in operations design and improvement that drive the famous Toyota Production System. They are removing ambiguity in the output, responsibilities, connections, and methods of their work processes. These changes-which can be done in the course of an ordinary workday, sometimes in a matter of hours-are designed to make the following crystal clear: Which patient gets which procedure (output); Who does which aspect of the job (responsibility); Exactly which signals are used to indicate that the work should begin (connection); and Precisely how each step is carried out (method). Equally important, managers are being transformed from rescuers who arrive with ready-made solutions into problem solvers who help colleagues learn the experimental method. Thus, these hospitals are breaking free of the work-around culture that routinely obscures the root causes of so many problems, creates so much waste, and leads to so many unnecessary deaths.

  16. Ancient water supports today's energy needs

    The water footprint for fossil fuels typically accounts for water utilized in mining and fuel processing, whereas the water footprint of biofuels assesses the agricultural water used by crops through their lifetime. Fossil fuels have an additional water footprint that is not easily accounted for: ancient water that was used by plants millions of years ago, before they were transformed into fossil fuel. How much water is mankind using from the past to sustain current energy needs? We evaluate the link between ancient water virtually embodied in fossil fuels to current global energy demands by determining the water demand required to replace fossil fuels with biomass produced with water from the present. Using equal energy units of wood, bioethanol, and biodiesel to replace coal, natural gas, and crude oil, respectively, the resulting water demand is 7.39 × 1013 m3 y-1, approximately the same as the total annual evaporation from all land masses and transpiration from all terrestrial vegetation. Thus, there are strong hydrologic constraints to a reliance on biofuel energy produced with water from the present because the conversion from fossil fuels to biofuels would have a disproportionate and unsustainable impact on the modern water. By using fossil fuels to meet today's energy needs, we are virtually using water from a geological past. The water cycle is insufficient to sustain the production of the fuel presently consumed by human societies. Thus, non-fuel-based renewable energy sources are needed to decrease mankind's reliance on fossil fuel energy without placing an overwhelming pressure on global freshwater resources.

    Full Text Available Today, more students in the US are attending university than ever before. An unprecedented number of these students were born digital—meaning digital technologies have been a constant feature in their lives. For these young adults, information literacy competencies are always being formed, practiced, and learned. Project Information Literacy (PIL is a series of ongoing quantitative and qualitative research studies in the US that investigates what it is like to be a university student in the digital age. This research study has investigated how students find information and conduct research—in their words and through their experiences—for coursework, use in their everyday lives, and, once they graduate, in the workplace and their communities. Since 2008, more than 11,000 university students at nearly 60 US higher education institutions have been surveyed or interviewed, making PIL the largest study of information literacy ever conducted. Results from PIL’s studies have concluded students’ information competencies are put to the test in the vast information landscape they inhabit. Furthermore, finding and using information is exponentially more complex than it was a generation ago, especially since the information landscape has shifted from one of scarce resources to one of overload. In this keynote, five research takeaways were presented from PIL’s eight studies: (1 Students find research more difficult than ever before, (2 getting started is the hardest part of research, (3 frustrations begin with finding context, i.e., big picture, information-gathering, language, and situational context, (4 search strategies are based on predictability, familiarity, and efficiency, and (5 evaluation is the one information skills most learn to use. Discussion included implications of these findings for teaching, learning, work, and librarianship in the 21st century.

    This descriptive study investigated the implementation practices of secondary science teachers who differentiate instruction. Participants included seven high school science teachers purposefully selected from four different schools located in a mid-Atlantic state. Purposeful selection ensured participants included differentiated instruction (DI) in their lesson implementation. Data included semi-structured interviews and field notes from a minimum of four classroom observations, selected to capture the variety of differentiation strategies employed. These data were analyzed using a constant-comparative approach. Each classroom observation was scored using the validated Differentiated Instruction Implementation Matrix-Modified, which captured both the extent to which critical indicators of DI were present in teachers' instruction and the performance levels at which they engaged in these components of DI. Results indicated participants implemented a variety of differentiation strategies in their classrooms with varying proficiency. Evidence suggested all participants used instructional modifications that required little advance preparation to accommodate differences in students' interests and learning profile. Four of the seven participants implemented more complex instructional strategies that required substantial advance preparation by the teacher. Most significantly, this study provides practical strategies for in-service science teachers beginning to differentiate instruction and recommendations for professional development and preservice science teacher education.

Using the Danish Integrated Database for Labour Market Research, we find that former gazelles are not able to sustain their headstart in terms of performance in the long run. We demonstrate that gazelles are often outperformed by initially slower growing competitors, as high initial growth negatively...... routine structure within the newly founded venture if expansion is undertaken too hastily. In turn, this impediment decreases these firms’ long-term performance, as the initial set of structures and routines or the lack thereof has a long-lasting effect on the organization’s development....

    Directory of Open Access Journals (Sweden)

    David C Marchant

    2011-01-01

    Full Text Available Research progress assessing the role of attentional focusing instructions on skill acquisition and performance has lead researchers to apply this approach to force production tasks. Initial converging evidence indicates that force production tasks are sensitive to verbal instruction; externally focused instructions (onto movement outcomes, or onto the object force is being exerted against are shown to be more beneficial than internally focused instructions (focusing attention onto the movements being executed. These benefits are observed for maximal and accurate force production, as well as the maintenance of force production in prolonged tasks. A range of mechanisms are identified supporting the proposal that an external focus promotes movement efficiency in line with energy and effort conservation. Future research is required to assess how this developing body of work interacts with the broader understanding of psychological and physiological factors implicated in the effective production, maintenance and limitation of maximal or sub-maximal forces.

    Many applications have irregular behavior --- non-uniform input data, input-dependent solvers, irregular memory accesses, unbiased branches --- that cannot be captured using today's automated performance modeling techniques. We describe new hierarchical critical path analyses for the \\Palm model generation tool. To create a model's structure, we capture tasks along representative MPI critical paths. We create a histogram of critical tasks with parameterized task arguments and instance counts. To model each task, we identify hot instruction-level sub-paths and model each sub-path based on data flow, instruction scheduling, and data locality. We describe application models that generate accurate predictions for strong scaling when varying CPU speed, cache speed, memory speed, and architecture. We present results for the Sweep3D neutron transport benchmark; Page Rank on multiple graphs; Support Vector Machine with pruning; and PFLOTRAN's reactive flow/transport solver with domain-induced load imbalance.

    deterrence in reassuring traditional allies confronting new hostile proliferators. In practice, however, extending deterrence in response to proliferation threats raises a number of difficult questions and will require adaptation of traditional approaches. But in other situations, what role, if any, deterrence - though not necessarily nuclear deterrence - should play is itself an open question. This applies perhaps most to possible efforts by the United States and other countries to bring to bear deterrence or other complementary strategies aimed at shaping a terrorist adversary's strategic calculus to help meet the threat of use of a nuclear weapon or other WMD attack by al- Qaeda and its Jihadist allies. Here, too, new thinking will be required to define and implement such complementary strategies for influencing the calculations of terrorist adversaries. But questions about the applicability - or at least complexities - of deterrence also are reflected in today's expressions of concern that some new nuclear powers may be 'non-deterrable' as well as that an asymmetric balance of stakes is creating a new deterrence equation outside of Europe. Regarding Russia, Moscow no longer is an adversary of the West but nor is it a friend - and moving beyond deterrence to a non-adversarial relationship so far has been more rhetoric than reality. As for China, the U.S. extended nuclear deterrent continues to play a role in helping to avoid a confrontation over Taiwan as well as in reassuring those officials in Asia that are uncertain about the ultimate impact of China's rise. That said, it would be preferable to mute the role of nuclear deterrence in the U.S.-China strategic relationship and, as with Russia, to develop a non-adversarial relationship between the United States and China.

    Harrison, David J.; Saito, Laurel; Markee, Nancy; Herzog, Serge

    2017-11-01

    To examine the impact of a hybrid-flipped model utilising active learning techniques, the researchers inverted one section of an undergraduate fluid mechanics course, reduced seat time, and engaged in active learning sessions in the classroom. We compared this model to the traditional section on four performance measures. We employed a propensity score method entailing a two-stage regression analysis that considered eight covariates to address the potential bias of treatment selection. First, we estimated the probability score based on the eight covariates, and second, we used the inverse of the probability score as a regression weight on the performance of learners who did not select into the hybrid course. Results suggest that enrolment in the hybrid-flipped section had a marginally significant negative impact on the total course score and a significant negative impact on homework performance, possibly because of poor video usage by the hybrid-flipped learners. Suggested considerations are also discussed.

    2017-02-01

    In an effort to maximize a student’s academic growth, one of the tools available to educators is the explicit instruction. Explicit instruction is marked by a series of support or scaffold, where the students will be guided through the learning process with a clear statement of purpose and a reason for learning new skills, a clear explanation and demonstration of learning targets, supported and practiced with independent feedback until mastery has been achieved. The technology development trend of todays, requires an adjustment in the development of learning object that supports the achievement of explicit instruction targets. This is where the gamification position is. In the role as a pedagogical strategy, the use of gamification preformance study class is still relatively new. Gamification not only use the game elements and game design techniques in non-game contexts, but also to empower and engage learners with the ability of motivation on learning approach and maintains a relaxed atmosphere. With using Reseach and Development methods, this paper presents the integration of technology (which in this case using the concept of gamification) in explicit instruction settings and the impact on the improvement of students’ understanding.

    MacNeil, James D

    2012-08-01

    The challenges facing analytical laboratories today are not unlike those faced in the past, although both the degree of complexity and the rate of change have increased. Challenges such as development and maintenance of expertise, maintenance and up-dating of equipment, and the introduction of new test methods have always been familiar themes for analytical laboratories, but international guidelines for laboratories involved in the import and export testing of food require management of such changes in a context which includes quality assurance, accreditation, and method validation considerations. Decisions as to when a change in a method requires re-validation of the method or on the design of a validation scheme for a complex multi-residue method require a well-considered strategy, based on a current knowledge of international guidance documents and regulatory requirements, as well the laboratory's quality system requirements. Validation demonstrates that a method is 'fit for purpose', so the requirement for validation should be assessed in terms of the intended use of a method and, in the case of change or modification of a method, whether that change or modification may affect a previously validated performance characteristic. In general, method validation involves method scope, calibration-related parameters, method precision, and recovery. Any method change which may affect method scope or any performance parameters will require re-validation. Some typical situations involving change in methods are discussed and a decision process proposed for selection of appropriate validation measures. © 2012 John Wiley & Sons, Ltd.

    Increasingly, high-fidelity patient simulation (HFPS) is becoming essential to nursing education. Much remains unknown about how classroom learning is connected to student decision-making in simulation scenarios and the degree to which transference takes place between the classroom setting and actual practice. The present study was part of a larger pilot study aimed at determining the relationship between nursing students' clinical ability to prioritize their actions and the associated cognitions and physiologic outcomes of care using HFPS. In an effort to better explain the knowledge base being used by nursing students in HFPS, the investigators explored the relationship between common measures of knowledge and performance-related variables. Findings are discussed within the context of the expert performance approach and concepts from cognitive psychology, such as cognitive architecture, cognitive load, memory, and transference.

    Full Text Available Inclusive differentiated instruction is a new model of didactic instruction, theoretically described and established in this paper for the first time, after being experimentally verified through teaching of the mother tongue (instruction in reading and literature. Inclusive individually planned instruction is based on a phenomenological and constructivist didactic instructional paradigm. This type of teaching is essentially developmental and person-oriented. The key stages of inclusive differentiated instruction of literature are: 1 recognition of individual students' potential and educational needs regarding reading and work on literary texts; 2 planning and preparation of inclusive individually planned instruction in reading and literature; 3 actual class teaching of lessons thus prepared; and 4 evaluation of the student achievement following inclusive differentiated instruction in reading and literature. A highly important element of the planning and preparation of inclusive differentiated instruction is the creation of student profiles and inclusive individualized syllabi. Individualized syllabi specify the following: 1. a brief student profile; 2. the student position on the continuum of the learning outcomes of instruction in the Serbian language; 3. reverse-engineered macro-plan stages of instruction in the Serbian language (3.1. identifying expected outcomes and fundamental qualities of learners' work, 3.2. defining acceptable proofs of their realisation, 3.3. planning learning and teaching experiences, and 3.4. providing material and technical requisites for teaching; 4 the contents and procedure of individualized lessons targeting the student; 5 a plan of syllabus implementation monitoring and evaluation. The continuum of the learning outcomes of inclusive differentiated instruction in literature exists at three main levels, A, B and C. The three levels are: A reading techniques and learning about the main literary theory concepts; B

    The current generation of nuclear power plants is approaching middle age. The industry continues to stabilize and mature as this occurs, which creates new areas of focus. This evolution is placing a much greater emphases on the business aspects of the operation and maintenance functions. One area that can provide a reasonable return to the operating organizations is materials management. Florida Power and Light Company has experienced these reasons for change. A new department was formed as part of the Nuclear Division in 1990. Performance improvement tasks were established using goals and objectives consistent with plant support and business requirements. Two of the primary processes within the materials management area control the largest portion of costs to operating budgets: the procurement process and inventory management

  3. [Competitiveness in science. Today, tomorrow, and forever].

    Paternalistic governments and highly bureaucratized administrations produce mediocre science policy decisions that often allow for the co-existence of potentially competitive scientists alongside with those that are not. This invariably results in failure to produce significant research. It seems apparent therefore, that policy change aiming at improving science and technology must begin with intensification of the level of individual competitiveness. Nations that have internationally competitive levels of technical and scientific activity such as Japan, USA and Canada, share in common certain features that foster individual competitiveness despite the fact that their socioeconomic basis are vastly different. These common features include administrative continuity, very high academic standards and a highly educated work force. The scientist's emotional cost in competitive environments is high but there seems to be no alternative given the sophistication of the topics that are dealt with in formerly purely descriptive sciences such as biomedicine, and given the enormous speed of electronic communications. The role of governments in fostering science and technology should be mainly concerned with conducting a sound fiscal policy in order to provide for the needs of education and scientific activity. Governments can also play a key role in insuring that science remains competitive through the delineation of rules that increase individual competitiveness rather than with policy schemes that fail to directly address the responsibility of the individual. Policies to increase individuals' performance may prove costly to politicians given that these adjustments imply unpopular decisions regarding an increase in academic performance expectation beginning in high school and the re-assignment of functions of individuals or institutions that do not meet international productivity criteria.

  4. Motivating Calculus-Based Kinematics Instruction with Super Mario Bros

    2011-09-01

    High-quality physics instruction is contextualized, motivates students to learn, and represents the discipline as a way of investigating the world rather than as a collection of facts and equations. Inquiry-oriented pedagogy, such as problem-based instruction, holds great promise for both teaching physics content and representing the process of doing real science.2 A challenge for physics teachers is to find instructional contexts that are meaningful, accessible, and motivating for students. Today's students are spending a growing fraction of their lives interacting with virtual environments, and these environments—physically realistic or not—can provide valuable contexts for physics explorations3-5 and lead to thoughtful discussions about decisions that programmers make when designing virtual environments. In this article, I describe a problem-based approach to calculus-based kinematics instruction that contextualizes students' learning within the Super Mario Bros. video game—a game that is more than 20 years old, but still remarkably popular with today's high school and college students.

  5. Using Technology-Nested Instructional Strategies to Enhance Student Learning

    2015-08-01

    Full Text Available Students today expect the use of technology in their classes, rather than have to listen to less-than-engaging lectures. College students are connected electronically and incessant technology consumers. As a result, they may prefer the infusion of technologies to help them learn and enjoy the process of learning, rather than having to listen exclusively to lectures. To investigate this, the authors solicited student perceptions to assess the importance of learning through technology-nested instructional strategies. Student perceptions give direction to and affirm the benefits of instructional strategies that increase student motivation to engage more actively in their learning. Based on quantitative and qualitative responses through action research in multiple courses, students perceive their learning as more engaging and enjoyable when technology-nested instructional strategies are infused into their classes.

    leadership and the physician team impact on the overall work atmosphere. Physicians unaware of the goals of the department as well as the hospital, that do not receive management performance feedback, and who do not get annual performance appraisals and career guidance, rate their psychosocial environment as more adverse than their colleagues. There is also a great need to offer personally targeted competence development plans. Heads of department and senior physicians rate their work environment as of higher quality than more junior and mid-career physicians. More specifically, less senior physicians perceive similar work demands as their senior colleagues but rate influence over work, skills utilization, and intellectual stimulation at work as significantly worse. In order to combat negative stressors in the physicians' work environment, enhancement initiatives should be considered both at the individual, group, and structural level. Successful resources used by physicians to manage the stress of everyday medicine should be identified. Physicians are a key group to ensure a well-functioning health care system. In order to be able to change and adapt to the ongoing evolution of the Western health care system, more focus needs to be put on the psychosocial aspects of physicians' work.

    If the super conductor industry settles out at a temperature of -100 0 F or above, mechanical refrigeration will be vying for the cooling business. Today there very definitely is a break point in the application of equipment at approximately -120 0 F or 189 0 K. Other technologies are generally utilized below this level. However, with market potential comes invention and breakthroughs in refrigeration can also occur. Today standard refrigeration systems are cost effective, reliable and produced in the millions for high temperature applications of +10 0 F to +40 0 F evaporator temperature. Lower temperatures require additional hardware, consume additional power and are produced today in limited quantities for special applications

  10. Cardiological-interventional therapy of coronary artery disease today

    International Nuclear Information System (INIS)

    Reynen, K.; Henssge, R.

    1999-01-01

    The current importance of the interventional therapy of coronary artery disease may be deduced from the exponential increase in procedures performed in Germany in the last decade - at least 125,840 in 1996. Today, by improved catheter and balloon materials as well as by growing experience of the cardiologists, even complex lesions may be treated. Limitations of balloon angioplasty include acute vessel closure and restenosis - newer angioplasty devices like directional or rotational atherectomy or excimer-laser angioplasty did not overcome these limitations; only by coronary stenting, acute vessel closure could be managed and the likelihood of restenosis - at least in particular groups of patients - could be reduced. For a few years, intracoronary brachytherapy of the segments dilated with beta- or gamma-emitters has been seeking to reduce restenosis rate; the department of cardiology of the Dresden Cardiovascular Institute is participating in such a multicentre study using the beta-emitter 188 renium. Further main topics of our department represent primary angioplasty in patients with acute myocardial infarction and invasive diagnostic or interventional procedures by the transradial approach.

    Ashauer, Shirley A; Macan, Therese

    2013-01-01

    Learning and adapting to change are imperative as teams today face unprecedented change. Yet, an important part of learning involves challenging assumptions and addressing differences of opinion openly within a group--the kind of behaviors that pose the potential for embarrassment or threat. How can leaders foster an environment in which team members feel it is safe to take interpersonal risks in order to learn? In a study of 71 teams, we found that psychological safety and learning behavior were higher for teams with mastery than performance goal instructions or no goal instructions. Team psychological safety mediated the relationship between mastery and performance goal instructions and learning behavior. Findings contribute to our understanding of how leader-assigned goals are related to psychological safety and learning behavior in a team context, and suggest approaches to foster such processes.

  10. Facility transition instruction

    International Nuclear Information System (INIS)

    Morton, M.R.

    1997-01-01

    The Bechtel Hanford, Inc. facility transition instruction was initiated in response to the need for a common, streamlined process for facility transitions and to capture the knowledge and experience that has accumulated over the last few years. The instruction serves as an educational resource and defines the process for transitioning facilities to long-term surveillance and maintenance (S and M). Generally, these facilities do not have identified operations missions and must be transitioned from operational status to a safe and stable configuration for long-term S and M. The instruction can be applied to a wide range of facilities--from process canyon complexes like the Plutonium Uranium Extraction Facility or B Plant, to stand-alone, lower hazard facilities like the 242B/BL facility. The facility transition process is implemented (under the direction of the US Department of Energy, Richland Operations Office [RL] Assistant Manager-Environmental) by Bechtel Hanford, Inc. management, with input and interaction with the appropriate RL division and Hanford site contractors as noted in the instruction. The application of the steps identified herein and the early participation of all organizations involved are expected to provide a cost-effective, safe, and smooth transition from operational status to deactivation and S and M for a wide range of Hanford Site facilities

    Mitchell, Cassie S; Cates, Ashlyn; Kim, Renaid B; Hollinger, Sabrina K

    2015-01-01

    Biocuration is a time-intensive process that involves extraction, transcription, and organization of biological or clinical data from disjointed data sets into a user-friendly database. Curated data is subsequently used primarily for text mining or informatics analysis (bioinformatics, neuroinformatics, health informatics, etc.) and secondarily as a researcher resource. Biocuration is traditionally considered a Ph.D. level task, but a massive shortage of curators to consolidate the ever-mounting biomedical "big data" opens the possibility of utilizing biocuration as a means to mine today's data while teaching students skill sets they can utilize in any career. By developing a biocuration assembly line of simplified and compartmentalized tasks, we have enabled biocuration to be effectively performed by a hierarchy of undergraduate students. We summarize the necessary physical resources, process for establishing a data path, biocuration workflow, and undergraduate hierarchy of curation, technical, information technology (IT), quality control and managerial positions. We detail the undergraduate application and training processes and give detailed job descriptions for each position on the assembly line. We present case studies of neuropathology curation performed entirely by undergraduates, namely the construction of experimental databases of Amyotrophic Lateral Sclerosis (ALS) transgenic mouse models and clinical data from ALS patient records. Our results reveal undergraduate biocuration is scalable for a group of 8-50+ with relatively minimal required resources. Moreover, with average accuracy rates greater than 98.8%, undergraduate biocurators are equivalently accurate to their professional counterparts. Initial training to be completely proficient at the entry-level takes about five weeks with a minimal student time commitment of four hours/week.

  19. Children Can Learn New Facts Equally Well From Interactive Media Versus Face to Face Instruction.

    2016-01-01

    Today's children have more opportunities than ever before to learn from interactive technology, yet experimental research assessing the efficacy of children's learning from interactive media in comparison to traditional learning approaches is still quite scarce. Moreover, little work has examined the efficacy of using touch-screen devices for research purposes. The current study compared children's rate of learning factual information about animals during a face-to-face instruction from an adult female researcher versus an analogous instruction from an interactive device. Eighty-six children ages 4 through 8 years (64% male) completed the learning task in either the Face-to-Face condition ( n = 43) or the Interactive Media condition ( n = 43). In the Learning Phase of the experiment, which was presented as a game, children were taught novel facts about animals without being told that their memory of the facts would be tested. The facts were taught to the children either by an adult female researcher (Face-to-Face condition) or from a pre-recorded female voice represented by a cartoon Llama (Interactive Media condition). In the Testing Phase of the experiment that immediately followed, children's memory for the taught facts was tested using a 4-option forced-choice paradigm. Children's rate of learning was significantly above chance in both conditions and a comparison of the rates of learning across the two conditions revealed no significant differences. Learning significantly improved from age 4 to age 8, however, even the preschool-aged children performed significantly above chance, and their performance did not differ between conditions. These results suggest that, interactive media can be equally as effective as one-on-one instruction, at least under certain conditions. Moreover, these results offer support for the validity of using interactive technology to collect data for research purposes. We discuss the implications of these results for children's learning

SIMD execution, or having a single instruction drive execution of an identical operation on multiple data items, was already well established as a technique to efficiently exploit data parallelism. Furthermore, support for it was already included in many commodity processors. However, in the past decade, SIMD execution has seen a dramatic increase in the set of

  6. The Effectiveness of Web-Based Instruction: An Initial Inquiry

    2002-10-01

    Full Text Available As the use of Web-based instruction increases in the educational and training domains, many people have recognized the importance of evaluating its effects on student outcomes such as learning, performance, and satisfaction. Often, these results are compared to those of conventional classroom instruction in order to determine which method is “better.” However, major differences in technology and presentation rather than instructional content can obscure the true relationship between Web-based instruction and these outcomes. Computer-based instruction (CBI, with more features similar to Web-based instruction, may be a more appropriate benchmark than conventional classroom instruction. Furthermore, there is little consensus as to what variables should be examined or what measures of learning are the most appropriate, making comparisons between studies difficult and inconclusive. In this article, we review the historical findings of CBI as an appropriate benchmark to Web-based instruction. In addition, we review 47 reports of evaluations of Web-based courses in higher education published between 1996 and 2002. A tabulation of the documented findings into eight characteristics is offered, along with our assessments of the experimental designs, effect sizes, and the degree to which the evaluations incorporated features unique to Web-based instruction.

    Automatic assistants could guide a person or a robot in performing new tasks, such as changing a car tire or repotting a plant. Creating such assistants, however, is non-trivial and requires understanding of visual and verbal content of a video. Towards this goal, we here address the problem of automatically learning the main steps of a task from a set of narrated instruction videos. We develop a new unsupervised learning approach that takes advantage of the complementary nature of the input video and the associated narration. The method sequentially clusters textual and visual representations of a task, where the two clustering problems are linked by joint constraints to obtain a single coherent sequence of steps in both modalities. To evaluate our method, we collect and annotate a new challenging dataset of real-world instruction videos from the Internet. The dataset contains videos for five different tasks with complex interactions between people and objects, captured in a variety of indoor and outdoor settings. We experimentally demonstrate that the proposed method can automatically discover, learn and localize the main steps of a task input videos.

    Instructor immediacy has been positively associated with many desirable academic outcomes including increased student learning. This study extends existing understanding of instructional immediacy behaviours in elearning by describing postgraduate nursing students' reflections on their own experience. An exploratory, descriptive survey design was used to collect qualitative data. Participants were asked what behaviours or activities help to create rapport or a positive interpersonal connection (immediacy) between students and their online teacher(s). Thematic analysis of the data revealed three main themes: acknowledging and affirming student's personal and professional responsibilities; providing clear and timely information; and utilising rich media. These findings give lecturers insight into instructional strategies they may adopt to increase immediacy in elearning and hence improve student learning outcomes.

    Puranik, Cynthia S; Al Otaiba, Stephanie; Sidler, Jessica Folsom; Greulich, Luana

    2014-02-01

    The objective of this exploratory investigation was to examine the nature of writing instruction in kindergarten classrooms and to describe student writing outcomes at the end of the school year. Participants for this study included 21 teachers and 238 kindergarten children from nine schools. Classroom teachers were videotaped once each in the fall and winter during the 90 minute instructional block for reading and language arts to examine time allocation and the types of writing instructional practices taking place in the kindergarten classrooms. Classroom observation of writing was divided into student-practice variables (activities in which students were observed practicing writing or writing independently) and teacher-instruction variables (activities in which the teacher was observed providing direct writing instruction). In addition, participants completed handwriting fluency, spelling, and writing tasks. Large variability was observed in the amount of writing instruction occurring in the classroom, the amount of time kindergarten teachers spent on writing and in the amount of time students spent writing. Marked variability was also observed in classroom practices both within and across schools and this fact was reflected in the large variability noted in kindergartners' writing performance.

    Franklin T. Thompson

    2014-02-01

    Full Text Available The reason why the Trayvon Martin murder trial and similar court cases create a philosophical rift in our nation is due in part to flaws in the delivery of multicultural education. Traditional multicultural instruction does not prepare citizens for the subtleties and complexities of race relations. This study investigates critical strategies and practices that address multicultural missing gaps. I also seek to fill a void in the literature created by a lack of student input regarding teaching strategies that encourage lifelong learning. Students (N = 337 enrolled at a Midwestern university were asked to rate the efficacy of selected instructional strategies. Utilizing a 9-point Likert-type scale, students gave themselves a personal growth rating of 7.15 (SD = 1.47. Variables important to predicting that growth (R2 = .56, p < .0005 were a six-factor variable known as a non-color-blind instructional approach (t = 10.509, p ≤ .0005, allowing students an opportunity to form their own opinions apart from the instructor (t = 4.797, p ≤ .0005, and a state law that mandated multicultural training (t = 3.234, p = .001. Results demonstrated that utilizing a 35% traditional and 65% critical pedagogy mixture when teaching multicultural education helped promote win/win scenarios for education candidates hoping to become difference makers.

    2014-12-01

    Today, the German-lead Cosmic Dust Analyser (CDA) is operated continuously for 10 years in orbit around Saturn. The first discovery of CDA related to Saturn was the measurement of nanometer sized dust particles ejected by to interplanetary space with speeds higher than 100 km/s. Their origin and composition was analysed and and their dynamical studies showed a strong link to the conditions of the solar wind plasma flow. A recent surprising result was, that stream particles stem from the interior of Enceladus. Since 2004 CDA measured millions of dust impacts characterizing the dust environment of Saturn. The instrument showed strong evidence for ice geysers located at the south pole of Saturn's moon Enceladus in 2005. Later, a detailed compositional analysis of the salt-rich water ice grains in Saturn's E ring system lead to the discovery of liquid water below the icy crust connected to an ocean at depth feeding the icy jets. CDA was even capable to derive a spatially resolved compositional profile of the plume during close Enceladus flybys. A determination of the dust-magnetosphere interaction and the discovery of the extended E ring allowed the definition of a dynamical dust model of Saturn's E ring describing the observed properties. The measured dust density profiles in the dense E ring revealed geometric asymmetries.In the final three years CDA performs exogenous and interstellar dust campaigns, studies of the composition and origin of Saturn's main rings by unique ring ejecta measurements, long-duration nano-dust stream observations, high-resolution maps of small moon orbit crossings, studies of the dust cloud around Dione and studies of the E-ring interaction with the large moon Titan.

    Full Text Available Adult students demand a wider variety of instructional strategies that encompass real-world, interactive, cooperative, and discovery learning experiences.Designing Instruction for the Traditional, Adult, and Distance Learner: A New Engine for Technology-Based Teaching explores how technology impacts the process of devising instructional plans as well as learning itself in adult students. Containing research from leading international experts, this publication proposes realistic and accurate archetypes to assist educators in incorporating state-of-the-art technologies into online instruction.This text proposes a new paradigm for designing, developing, implementing, and assessed technology-based instruction. It addresses three target populations of today's learner: traditional, adult, and distance education. The text proposes a new model of instructional system design (ISD for developing effective technology-based education that involves a five-step process focusing on the learner, learning theories, resources, delivery modalities, and outcomes.

  5. USING GOOGLE+ FOR INSTRUCTION

    Directory of Open Access Journals (Sweden)

    Kevin YEE

    Full Text Available Introduced in July, 2011 in a beta test of invited users only, the new social media service Google+ (or G+ quickly spread by word of mouth, and Google leader Larry Page (2011 blogged that within sixteen days it had 10 million users. By August, it had 25 million users (Cashmore, 2011. Even with slower growth ahead (still with no marketing budget, the service looks likely to crest 100 million users perhaps as early as ten months, a feat that took Facebook three years. Other social networks, most notably Facebook and Twitter, have been used increasingly as instructional tools, since they are platforms with which students are already familiar (Maloney, 2007; McLoughlin & Lee, 2007. Selwyn (2009 found that students often eschew official channels for communication in favor of less formal community-based formats such as Facebook, implying a growing need for instructional communication tools that will be used willingly by students. The question is whether Google+ can be used like Twitter or Facebook to augment instruction, or even, perhaps, to improve upon those predecessors for academic purposes. Google+ is like Twitter in that anyone can follow a given user’s posts. There is no direct “friend” relationship required to read the posts written by others. However, it also approximates some features of Facebook. Rather than friends sorted into “lists” like in Facebook, Google+ allows users to place feeds into one or more “circles,” the better to monitor (or control the flow of information to and from different audiences. Circles are more intuitive, and more central to the experience, than the Facebook lists. They provide an explicit organizational structure, compared to the less-obvious listing functionality, which feels like an afterthought, found in Facebook.

    Feng, Yuanyuan; Wong, Christopher; Park, Adrian; Mentis, Helena

    2016-03-01

    Although simulation-based training allows residents to become proficient in surgical skills outside the OR, residents still depend on senior surgeons' guidance in transferring skills accumulated from simulators into the operating room. This study aimed to identify and classify explicit instructions made by attending surgeons to their residents during laparoscopic surgery. Through these instructions, we examined the role gaze guidance plays in OR-based training. A total of ten laparoscopic cholecystectomy cases being performed by PGY4 residents were analyzed. The explicit directional instructions given by the mentoring attending surgeons to their residents were identified and classified into four categories based on their locations in the coordinate system. These categories were further combined into two classes, based on the target of instructions. The frequencies of instructions in the two classes were compared, and effect size was calculated. There were 1984 instructions identified in the ten cases. The instructions were categorized into instrument guidance (38.51%) and gaze guidance (61.49%). The instrument guidance focused on moving the instruments to perform surgical tasks, including directions to targets, instrument manipulation, and instrument interaction. The gaze guidance focused on achieving common ground during the operation, including target identification and target fixation. The frequency of gaze guidance is significantly higher than instrument guidance in a laparoscopic cholecystectomy (p guidance has become the main focus of OR-based training. The results show a tight connection between adopting expert gaze and performing surgical tasks and suggest that gaze training should be integrated into the simulation training.

    2012-05-01

    Full Text Available This study aims at contributing to the investigation on the instruction of EST (English for Science and Technology vocabulary, in terms of receptive use of the language. It evaluates the effectiveness of two teaching approaches to the acquisition of vocabulary. The first approach consisted of teaching vocabulary through the use of dictionaries, where the words were merely translated into the learners’ L1 or defined in the target language thus promoting superficial level of word processing. The second approach employed activities promoting deep level of word processing. Data were analysed quantitatively. Results indicated that the two approaches seem to have some equipotentiality, as far as EST vocabulary is concerned.

  10. The Mere Exposure Instruction Effect.

    Science.gov (United States)

    Van Dessel, Pieter; Mertens, Gaëtan; Smith, Colin Tucker; De Houwer, Jan

    2017-09-01

    The mere exposure effect refers to the well-established finding that people evaluate a stimulus more positively after repeated exposure to that stimulus. We investigated whether a change in stimulus evaluation can occur also when participants are not repeatedly exposed to a stimulus, but are merely instructed that one stimulus will occur frequently and another stimulus will occur infrequently. We report seven experiments showing that (1) mere exposure instructions influence implicit stimulus evaluations as measured with an Implicit Association Test (IAT), personalized Implicit Association Test (pIAT), or Affect Misattribution Procedure (AMP), but not with an Evaluative Priming Task (EPT), (2) mere exposure instructions influence explicit evaluations, and (3) the instruction effect depends on participants' memory of which stimulus will be presented more frequently. We discuss how these findings inform us about the boundary conditions of mere exposure instruction effects, as well as the mental processes that underlie mere exposure and mere exposure instruction effects.

    Katharina eMura

    2013-12-01

    Full Text Available Receiving informative, well-structured, and well-designed instructions supports performance and memory in assembly tasks. We describe IBES, a tool with which users can quickly and easily create multimedia, step-by-step instructions by segmenting a video of a task into segments. In a validation study we demonstrate that the step-by-step structure of the visual instructions created by the tool corresponds to the natural event boundaries, which are assessed by event segmentation and are known to play an important role in memory processes. In one part of the study, twenty participants created instructions based on videos of two different scenarios by using the proposed tool. In the other part of the study, ten and twelve participants respectively segmented videos of the same scenarios yielding event boundaries for coarse and fine events. We found that the visual steps chosen by the participants for creating the instruction manual had corresponding events in the event segmentation. The number of instructional steps was a compromise between the number of fine and coarse events. Our interpretation of results is that the tool picks up on natural human event perception processes of segmenting an ongoing activity into events and enables the convenient transfer into meaningful multimedia instructions for assembly tasks. We discuss the practical application of IBES, for example, creating manuals for differing expertise levels, and give suggestions for research on user-oriented instructional design based on this tool.

  16. Metacognitive instruction in middle school science

    Science.gov (United States)

    Bonney, Dianna

    The purpose of this action research project was to determine the extent to which metacognitive instruction affected students' performance in the middle-grade science classroom. Conducted with four seventh grade science classes over a three-month time period, 105 students were engaged in 21 metacognitively enhanced lessons. Both quantitative and qualitative data sources were collected for this study and analyzed according to grounded theory methodology. Quantitative data came from the Jr. Metacognitive Awareness Inventory, administered as a pre-post test. Qualitative teacher-generated data was collected in a metacognitive observation protocol containing observations and reflections while student-generated data was gathered from reflective journal entries, modified rubrics, and checklists. Analysis of the data led to the assertions that metacognitive development occurred over time through systematic and varied implementation of explicit instruction. In addition, students perceived they learned best both when working collaboratively and when making multiple connections with content material. Implications for middle-grade teachers include the need for explicit instruction of metacognitive strategies, providing for instructional variation and student collaboration, and guiding students in making connections to prior learning.

  20. The Future of Foreign Language Instructional Technology: BYOD MALL

    Directory of Open Access Journals (Sweden)

    Jack Burston

    2016-05-01

    Full Text Available This paper describes trends in instructional technology that are influencing foreign language teaching today and that can be expected to increasingly do so in the future. Though already an integral part of foreign language instruction, digital technology is bound to play an increasing role in language teaching in the coming years. The greatest stimulus for this will undoubtedly be the accessibility of Mobile-Assisted Language Learning (MALL, made possible through the exploitation of mobile devices owned by students themselves. The ubiquitous ownership of smartphones and tablet computers among adolescents and adults now makes a Bring Your Own Device (BYOD approach a feasible alternative to desktop computer labs. Making this work, however, especially in a financially and technologically restricted environment, presents a number of challenges which are the focus of this paper.

  1. The equivalence of learning paths in early science instruction: effect of direct instruction and discovery learning.

    Science.gov (United States)

    Klahr, David; Nigam, Milena

    2004-10-01

    In a study with 112 third- and fourth-grade children, we measured the relative effectiveness of discovery learning and direct instruction at two points in the learning process: (a) during the initial acquisition of the basic cognitive objective (a procedure for designing and interpreting simple, unconfounded experiments) and (b) during the subsequent transfer and application of this basic skill to more diffuse and authentic reasoning associated with the evaluation of science-fair posters. We found not only that many more children learned from direct instruction than from discovery learning, but also that when asked to make broader, richer scientific judgments, the many children who learned about experimental design from direct instruction performed as well as those few children who discovered the method on their own. These results challenge predictions derived from the presumed superiority of discovery approaches in teaching young children basic procedures for early scientific investigations.

    If the world runs on energy, the energy industry runs on finance. Supplying the industry's huge appetite for funds -on the scale and in the form required - has always posed a major challenge to the international banking community. But in some respects that challenge is greater today than it has ever been, not only because of the industry's escalating requirements but also because of the way bank's attitudes have been changing in the recent past. One reason for this is the rapidly evolving scene within the energy business in response to the harsher competitive conditions and the greater uncertainties of tomorrow. However, the other major factor is that banking itself has been undergoing significant change as a result of severe pressures and constraints, both internal and external. Some of the key global trends and issues affecting energy financing in today's world are considered here. (author)

    This paper explains why the question is how, not if, today's financial statements should include estimates of the future. Including such estimates is not new, but their use is increasing. This increase results primarily because standard setters believe asset and liability measures that reflect current economic conditions and up-to-date expectations of the future will result in more useful information for making economic decisions, which is the objective of financial reporting. This is why sta...

  18. Energy supply today and tomorrow, national and global

    International Nuclear Information System (INIS)

    Ott, G.

    2003-01-01

    A status report about 'Energy Supply Today and Tomorrow, National and Global' focuses mainly on global aspects. Today's world energy consumption is dominated by more than 80% of fossil sources of energy followed by so-called non-commercial energies, such as wood and plant and animal wastes, contributing 10%; nuclear power, 7%; and hydroelectric power, 2%. The development of energy consumption until the middle of this century will continue to be driven by the further growth of the world population, and by the need to meet the rising demand for energy in the developing countries. Because of their availability and flexible uses, oil, natural gas, and coal as fossil sources of energy will continue to meet a considerable share of the requirement. The use of nuclear power, a source meeting all criteria, such as safety, waste management, and competitiveness, is both justifiable and desirable. Restrictive decisions about nuclear power taken today must not impair the freedom of choice of future generations. Using renewable energies is just as desirable as increasing energy efficiency; however, the technical and physical potentials available for this purpose should not be overrated. This makes it imperative to protect the supply of energy 'in this difficult interim phase' with all the options available, and to open up prospects for the future, also by conducting the appropriate energy and environmental research. The balance between continuity of supply, environmental compatibility, and competitiveness must be taken into account in this effort. In the second half of the 21 st century, it is possible that energy consumption will stabilize when the world's population ceases to grow. New technologies, some of which may not even be known today or may still be under development, could then pave the way for an energy supply system which, in toto, would be less of a burden on the environment.

    Smith, Derek R; Watson, Roger

    2016-11-01

    A discussion of bibliometrics, altmetrics and social media for the contemporary nursing scholar and academic researcher. Today's nursing academic faces myriad challenges in balancing their daily life and, in recent years, academic survival has been increasingly challenged by the various research assessment exercises that evaluate the performance of knowledge institutions. As such, it is essential that today's nursing academic keep up to date with the core competencies needed for survival in a modern research career, particularly the intersecting triad of bibliometrics, altmetrics and social media. Discussion paper. Published literature and relevant websites. The rise of social media and altmetrics has important implications for contemporary nursing scholars who publish their research. Some fundamental questions when choosing a journal might be 'does it have a Twitter and/or Facebook site, or a blog (or all three)'; and 'does it have any other presence on social media, such as LinkedIn, Wikipedia, YouTube, ResearchGate and so on?' Another consequence of embracing social media is that individual academics should also develop their own strategies for promoting and disseminating their work as widely as possible. The rising importance of social media and altmetrics can no longer be ignored, and today's nursing academic now has another facet to consider in their scholarly activities. Despite the changing nature of research dissemination, however, it is still important to recognize the undoubted value of established knowledge dissemination routes (that being the peer-reviewed publication). © 2016 John Wiley & Sons Ltd.

  5. On sociological criteria of religiousness: How many (Orthodox believers are there today?

    Directory of Open Access Journals (Sweden)

    Blagojević Mirko

    2009-01-01

    Full Text Available In this text the author first tries to provide an answer on the number of religious people today in two post-communist and Orthodox countries, and then on the number of Orthodox believers in them. Therefore he analyzes numerous data from empirical evidence using a large number of indicators discussed in the text. The author first analyzes them as indicators of representative dimension of religiousness, then as indicators of beliefs in dogmatic core of Christianity, indicators of current church ritual practice and finally, as indicators of a traditional attitude towards religion and church. With these analyses the author tries to find the criterion or criteria which best express the religiousness of people in a particular area. The analysis identifies three approaches in Russian sociological and religious literature. The first one is defined as a classic, positivistic approach, the second one as post-classic or phenomenological, and the third one as synthetic. Then the author discusses the term attachment to religion and church and its indicators, as well as the indices which are sociologically more suitable for the research of the religious and church complex. In the end the author gives a few methodological instructions for a sociological and empirical research of religiousness.

  6. Traditional microscopy instruction versus process-oriented virtual microscopy instruction: a naturalistic experiment with control group.

    Helle, Laura; Nivala, Markus; Kronqvist, Pauliina; Gegenfurtner, Andreas; Björk, Pasi; Säljö, Roger

    2011-03-30

    Virtual microscopy is being introduced in medical education as an approach for learning how to interpret information in microscopic specimens. It is, however, far from evident how to incorporate its use into existing teaching practice. The aim of the study was to explore the consequences of introducing virtual microscopy tasks into an undergraduate pathology course in an attempt to render the instruction more process-oriented. The research questions were: 1) How is virtual microscopy perceived by students? 2) Does work on virtual microscopy tasks contribute to improvement in performance in microscopic pathology in comparison with attending assistant-led demonstrations only? During a one-week period, an experimental group completed three sets of virtual microscopy homework assignments in addition to attending demonstrations. A control group attended the demonstrations only. Performance in microscopic pathology was measured by a pre-test and a post-test. Student perceptions of regular instruction and virtual microscopy were collected one month later by administering the Inventory of Intrinsic Motivation and open-ended questions. The students voiced an appreciation for virtual microscopy for the purposes of the course and for self-study. As for learning gains, the results indicated that learning was speeded up in a subgroup of students consisting of conscientious high achievers. The enriched instruction model may be suited as such for elective courses following the basic course. However, the instructional model needs further development to be suited for basic courses.

    In 1992, one year after the detection of a leak in a vessel head of the Electricite de France (EDF) Bugey 4 reactor, the head was replaced by the Framatome-Jeumont Industrie Group. Today, this group, which has developed new methods and new tools to optimize the cost, the time-delay and the dosimetry of this kind of intervention, has performed 11 additional replacements, two of which on 1300 MWe power units. This paper describes step by step the successive operations required for a complete vessel head replacement, including the testing of safety systems before starting up the reactor. (J.S.). 7 photos

    2004-09-01

    Full Text Available Years ago, exploration was done through surface observations and „divining rods“ – now, it is done by satellites, microprocessors, remote sensing, and supercomputers. In the 1970´ s, the exploration success rate was 14 percent, today, it is nearly 29 percent. Not so long ago, three – dimension (3D seismic diagnostic techniques helped recover 25-50 percent of the oil in place – now, 4D seismic helps recover up to 70 percent of the oil in place. 3D and 4D seismic and earth imaging systems also help in understanding the subsurface flow of other fluids, such as groundwater and pollutants.Seismic surveys – a technique in which sound waves are bounced off underground rock struktures to reveal possible oil and gas bearing formation – are now standard fare for the modern petroleum industry. But today’s seismic methods are best at locating „structural traps“ where faults or folds in the underground rock have created zones where oil can become trapped.

  14. Instructional Technology and Objectification

    Directory of Open Access Journals (Sweden)

    Bekir S. Gur

    2008-05-01

    Full Text Available Objectification refers to the way in which everything (including human beings is treated as an object, raw material, or resource to be manipulated and used. In this article, objectification refers to the way that education is often reduced to the packaging and delivery of information. A critique of objectification in instructional technology is presented. In the context of Heidegger’s critique of technology, the authors claim that objectification in education is metaphysical in the sense that the intelligibility (being of education is equated with ready-to-use packages, and thus is reduced to delivery and transmission of objects. The embodiment dimension of teaching and learning can help us in resisting this reduction. The authors argue that objectification increases bureaucratic control over the teaching process and deskills teachers; and by which teachers are proletarianized. The authors conclude that instructional designers should create structures in which a care relation and dialogue between students and teachers can take place. Résumé: L’objectification réfère à la façon dont tout (incluant les être humains est traité comme un objet, une matière première ou une ressource qui peut être manipulée et utilisée. Dans cet article, l’objectification réfère à la façon dont l’éducation est souvent réduite à la mise en boîte et à la livraison de l’information. Une critique de l’objectification en technologie éducative est présentée. Dans le contexte de la critique de la technologie par Heidegger, les auteurs prétendent que l’objectification en éducation est métaphysique dans le sens que l’intelligibilité (être de l’éducation équivaut à la mise en boîte prêt-à –utiliser, et se résume donc à la livraison et à la transmission d’objets. L’incarnation de l’enseignement et de l’apprentissage peuvent nous aider à résister à cette réduction. Les auteurs arguent que l

  17. Generalization of socially transmitted and instructed avoidance

    Directory of Open Access Journals (Sweden)

    2015-06-01

    Full Text Available Excessive avoidance behavior, in which an instrumental action prevents an upcoming aversive event, is a defining feature of anxiety disorders. Left unchecked, both fear and avoidance of potentially threatening stimuli may generalize to perceptually related stimuli and situations. The behavioral consequences of generalization mean that aversive learning experiences with specific threats may lead people to infer that classes of related stimuli are threatening, potentially dangerous, and need to be avoided, despite differences in physical form. Little is known about avoidance generalization in humans and the learning pathways by which it may be transmitted. In the present study, we compared two pathways to avoidance, instructions and social observation, on subsequent generalization of avoidance behavior, fear expectancy and physiological arousal. Participants first learned that one cue was a danger cue (conditioned stimulus, CS+ and another was a safety cue (CS-. Groups then were either instructed that a simple avoidance response in the presence of the CS+ cancelled upcoming shock presentations (instructed-learning group or observed a short movie showing a demonstrator performing the avoidance response to prevent shock (observational-learning group. During generalization testing, danger and safety cues were presented along with generalization stimuli that parametrically varied in perceptual similarity to the CS+. Reinstatement of fear and avoidance was also tested. Findings demonstrate, for the first time, generalization of socially transmitted and instructed avoidance: both groups showed comparable generalization gradients in fear expectancy, avoidance behavior and arousal. Return of fear was evident, suggesting that generalized avoidance remains persistent following extinction testing. The utility of the present paradigm for research on avoidance generalization is discussed.

    2004-01-01

    Experience and knowledge gained from ongoing maintenance of Space Shuttle Flight Software and new development projects including Cockpit Avionics Upgrade are applied to projected needs of the National Space Exploration Vision through Spiral 2. Lessons learned from these current activities are applied to create a sustainable, reliable model for development of critical software to support Project Constellation. This presentation introduces the technologies, methodologies, and infrastructure needed to produce and sustain high quality software. It will propose what is needed to support a Vision for Space Exploration that places demands on the innovation and productivity needed to support future space exploration. The technologies in use today within FSW development include tools that provide requirements tracking, integrated change management, modeling and simulation software. Specific challenges that have been met include the introduction and integration of Commercial Off the Shelf (COTS) Real Time Operating System for critical functions. Though technology prediction has proved to be imprecise, Project Constellation requirements will need continued integration of new technology with evolving methodologies and changing project infrastructure. Targets for continued technology investment are integrated health monitoring and management, self healing software, standard payload interfaces, autonomous operation, and improvements in training. Emulation of the target hardware will also allow significant streamlining of development and testing. The methodologies in use today for FSW development are object oriented UML design, iterative development using independent components, as well as rapid prototyping . In addition, Lean Six Sigma and CMMI play a critical role in the quality and efficiency of the workforce processes. Over the next six years, we expect these methodologies to merge with other improvements into a consolidated office culture with all processes being guided by

  19. Use of a virtual environment to facilitate instruction of an interprofessional home assessment.

    Sabus, Carla; Sabata, Dory; Antonacci, David

    2011-01-01

    Technology has become a ubiquitous part of our society and is largely embedded in today's educational system. 3D virtual reality technology can be used to simulate environments and activities and may be used as an instructional technology. The purpose of this research was to better understand the utility of a web-based virtual environment as a teaching tool to represent clinical assessment and interventions in the home environment. Specifically, students' learning outcomes related to interprofessional collaboration, patient-centered decision-making, and appreciation of the environmental and social context of functional mobility and occupational performance will be described through descriptive analysis. Thirty-four physical therapist students and 35 occupational therapist students participated in an instructor-guided virtual assessment of a client's function in a home environment utilizing a virtual environment, Second Life®. Teams formulated task-specific, functional client goals and home modification recommendations. Students revisited a solution virtual environment to view and evaluate recommendations in a follow-up instructor-guided tour. Students completed a web-based survey capturing student perception of the experience. Team assignments were analyzed based on a rubric representing learning objectives. Descriptive analysis was conducted on the survey. Assignment analysis revealed contextual and client-centered recommendations. Student surveys revealed that students found the virtual environment supportive of learning. Student surveys and reflection statements were supportive of the interprofessional collaboration. Use of a virtual environment in instruction allows an authentic means of representing interprofessional home assessment. The virtual environment allowed a temporal depiction of home environment issues and solutions providing the unique opportunity for students to evaluate home recommendations.

  20. Instructional scientific humor in the secondary classroom

    Science.gov (United States)

    Wizner, Francine

    This study is an examination of the manner in which educators employ scientific content humor and how that humor is perceived by their students. Content humor is a useful strategy in drawing the attention of students and improving their receptivity toward scientific information. It is also a useful tool in combating the growing distractions of the electronic classroom. Previous studies have found that humor has a positive effect on knowledge, memory, and understanding. However, few studies have been conducted below the undergraduate level and mainly quantitative measures of student recall have been used to measure learning. This study employed multiple data sources to determine how two secondary biology teachers used humor in order to explain scientific concepts and how their students perceived their teachers' use of scientific instructional humor. Evidence of student humor reception was collected from four students in each of the two classes. All of the scientific instructional humor used in the studied classrooms was cognitive in nature, varying among factual, procedural, conceptual, and metacognitive knowledge. Teachers tended to use dialogic forms of humor. Their scientific humor reflected everyday experiences, presented queries, poked fun at authority, and asked students to search out new perspectives and perform thought experiments. Teachers were the primary actors in performing the humorous events. The events were sometimes physical exaggerations of words or drawings, and they occurred for the purpose of establishing rapport or having students make connections between scientific concepts and prior knowledge. Student perceptions were that teachers did employ humor toward instructional objectives that helped their learning. Helping students become critical thinkers is a trademark of science teachers. Science teachers who take the risk of adopting some attributes of comedians may earn the reward of imparting behaviors on their students like critical thinking
