    Parkes, Jacqueline; O'Dell, Cindy

    2015-11-01

    It is more than a decade since the UK Central Council for Nursing Midwifery and Health Visiting said that engaging with clinical audit is 'the business of every registered practitioner', yet there appears to be little evidence that nursing has embraced the process. To address this issue, Northampton General Hospital and the University of Northampton implemented a pilot project in which two third-year adult nursing students worked on a 'real life' audit. Supported by the hospital's audit department, and supervised by academic tutors with the relevant experience, the students worked on a pressure-ulcer care audit for their final year dissertation. This article describes the process undertaken by the hospital audit team and the university academic team to develop the pilot project and support the students. Based on the positive evaluations, the university has extended the project to a second phase, incorporating two new partner organisations. PMID:26508069

  8. Introducing Dialogic Teaching to Science Student Teachers

    NASA Astrophysics Data System (ADS)

    Lehesvuori, Sami; Viiri, Jouni; Rasku-Puttonen, Helena

    2011-12-01

    It is commonly believed that science teachers rely on language that allows only minor flexibility when it comes to taking into account contrasting views and pupil thoughts. Too frequently science teachers either pose questions that target predefined answers or simply lecture through lessons, a major concern from a sociocultural perspective. This study reports the experiences of science student teachers when introduced to the Communicative Approach to science education drawing on dialogic teacher-talk in addition to authoritative teacher-talk. This approach was introduced to the students in an interventional teaching program running parallel to the student teachers' field practice. The practical implications of this approach during initial teacher education are the central focus of this study. The data consisting of videos of lessons and interviews indicate that the student teacher awareness of teacher-talk and alternative communicative options did increase. Student teachers reported greater awareness of the different functions of teacher-talk as well as the challenges when trying to implement dialogic teaching.

    PubMed

    Aud, Myra A; Bostick, Jane E; Marek, Karen Dorman; McDaniel, Roxanne W

    2006-01-01

    The faculty at the University of Missouri-Columbia Sinclair School of Nursing (MUSSON) developed and implemented a gerontological nursing care course, with support from the Health Resources and Services Administration, the American Association of Colleges of Nursing, and the John A. Hartford Foundation. The course, with both didactic and clinical components, was mandatory for all students in the baccalaureate program. The course drew on two resources unique to the MUSSON: Senior Care, the school's home care agency, and TigerPlace, a retirement community closely linked to the school. Goals of the course were to increase knowledge of gerontology and gerontological nursing and to promote more positive student attitudes toward older adults. Evaluation of six semesters of pretest and posttest data found that knowledge increased although attitudes toward older adults did not become more positive. However, despite the lack of quantifiable improvement in attitudes, some students wrote positive comments on end-of-semester course evaluations about experiences and interactions with older adults during the course.

  3. Introducing student inquiry in large introductory genetics classes.

    PubMed Central

    Pukkila, Patricia J

    2004-01-01

    An appreciation of genetic principles depends upon understanding the individual curiosity that sparked particular investigations, the creativity involved in imagining alternative outcomes and designing experiments to eliminate these outcomes, and the clarity of thought necessary to convince one's scientific peers of the validity of the conclusions. At large research universities, students usually begin their study of genetics in large lecture classes. It is widely assumed that the lecture format, coupled with the pressures to be certain that students become familiar with the principal conclusions of genetics investigations, constrains most if not all departures from the formats textbooks used to explain these conclusions. Here I present several examples of mechanisms to introduce meaningful student inquiry in an introductory genetics course and to evaluate student creative effort. Most of the examples involve altered student preparation prior to class and additional in-class activities, while a few depend upon a smaller recitation section, which accompanies the course from which the examples have been drawn. I conclude that large introductory classes are suitable venues to teach students how to identify scientific claims, determine the evidence that is essential to eliminate alternative conclusions, and convince their peers of the validity of their arguments.

  4. Moon 101: Introducing Students to Lunar Science and Exploration

    NASA Astrophysics Data System (ADS)

    Shaner, A. J.; Shipp, S. S.; Allen, J. S.; Kring, D. A.

    2011-12-01

    , students are asked a series of questions which help reinforce the lunar science concepts they should take away from the readings. Students then use their new knowledge of the Moon in the final section of Moon 101 where they are asked to characterize the geology of the region surrounding the Apollo 11 landing site. To do this, they conduct a survey of available lunar data, examining imagery from lunar missions as recent as the Lunar Reconnaissance Orbiter and as old as the Ranger missions of the 1960s. This allows students to explore the available datasets and identify the advantages and disadvantages of each. Pre/post test questions have also been developed to assess changes in student understanding of the formation and evolution of the Moon, and lunar exploration. Moon 101 is a framework for introducing students to lunar science, and can be followed up with student-driven research. Moon 101 can be easily modified to suit the needs of the students and the instructor. Because lunar science is an evolving field of study, the use of resources such as the PSRD allows Moon 101 to be flexible and to change as the lunar community re-discovers our celestial neighbor.

  2. Using Crickets to Introduce Neurophysiology to Early Undergraduate Students

    PubMed Central

    Dagda, Ruben K.; Thalhauser, Rachael M.; Dagda, Raul; Marzullo, Timothy C.; Gage, Gregory J.

    2013-01-01

    Anatomy and physiology instructors often face the daunting task of teaching the principles of neurophysiology as part of a laboratory course with very limited resources. Teaching neurophysiology can be a difficult undertaking as sophisticated electrophysiology and data acquisition equipment is often financially out-of-reach for two-year institutions, and for many preparations, instructors need to be highly skilled in electrophysiology techniques when teaching hands-on laboratories. In the absence of appropriate laboratory tools, many undergraduate students have difficulty understanding concepts related to neurophysiology. The cricket can serve as a reliable invertebrate model to teach the basic concepts of neurophysiology in the educational laboratory. In this manuscript, we describe a series of hands-on, demonstrative, technologically simple, and affordable laboratory activities that will help undergraduate students gain an understanding of the principles of neurophysiology. By using the cerci ganglion and leg preparation, students can quantify extracellular neural activity in response to sensory stimulation, understand the principles of rate coding and somatotopy, perform electrical microstimulation to understand the threshold of sensory stimulation, and do pharmacological manipulation of neuronal activity. We describe the utility of these laboratory activities, provide a convenient protocol for quantifying extracellular recordings, and discuss feedback provided by undergraduate students with regards to the quality of the educational experience after performing the lab activities.

  13. Student seminar on smoking: A novel way to introduce different perspectives on smoking to medical students

    PubMed Central

    Iqbal, Saima P.; Rafi, Shahid; Rahman, Matiur

    2013-01-01

    Background: The respiratory module at Shifa College of Medicine (SCM) is delivered in third year with emphasis on respiratory pathophysiology and respiratory medicine. Smoking as a topic was introduced to emphasize the preventive aspects of respiratory illnesses. An innovative approach to involve students in their learning was developed. To determine whether this innovation would be well received and effective for students’ learning about smoking, we carried out this study. Materials and Methods: This is a one group post-test quasi-experiment. Two days were assigned for a smoking seminar. The class of 106 students was divided into 10 batches, and each batch was assigned a theme related to smoking. These themes were developed by the faculty, and each theme was related to a different perspective on smoking. A post-test questionnaire was distributed at the end of the seminar for feedback to see what aspects of students’ learning were highlighted and what needed to be improved upon. Questions related to the usefulness of the activity were incorporated into the questionnaire and the students were asked to agree or disagree on a five-point Likert scale. Results: Most (68.3%) students agreed that this activity improved their knowledge regarding smoking, and 54.8% agreed that it also helped in application of this knowledge. Improvement in presentation and counseling skills (59.8%), evidence-based medicine (47.6%), and softer skills, such as teamwork (72%) and creativity (63.4%), were also reported to be enhanced. Conclusion: Seminars led by the students have shown to be effective in breaking the monotony and generating an interest of the topic. Such an activity serves as a small step to make our graduates more empathic, humane, competent, and skilful. PMID:23930124

    Segarra, Ignacio; Gomez, Manuel

    2014-12-01

    We developed a pharmacology practicum assignment to introduce students to the research ethics and steps involved in a clinical trial. The assignment included literature review, critical analysis of bioethical situations, writing a study protocol and presenting it before a simulated ethics committee, a practice interview with a faculty member to obtain informed consent, and a student reflective assessment and self-evaluation. Students were assessed at various steps in the practicum; the learning efficiency of the activity was evaluated using an independent survey as well as students' reflective feedback. Most of the domains of Bloom's and Fink's taxonomies of learning were itemized and covered in the practicum. Students highly valued the translatability of theoretical concepts into practice as well as the approach to mimic professional practice. This activity was within a pharmacy program, but may be easily transferable to other medical or health sciences courses. PMID:25747690

    PubMed

    Krilowicz, B I; Henter, H; Kamhi-Stein, L

    1997-06-01

    Providing large numbers of general education students with an introduction to science is a challenge. To meet this challenge, a quarter-long neurophysiology project was developed for use in an introductory biology course. The primary goals of this multistep project were to introduce students to the scientific method, scientific writing, on-line scientific bibliographic databases, and the scientific literature, while improving their academic literacy skills. Students began by collecting data on their own circadian rhythms in autonomic, motor, and cognitive function, reliably demonstrating the predicted circadian changes in heart rate, eye-hand coordination, and adding speed. Students wrote a journal-style article using pooled class data. Students were prepared to write the paper by several methods that were designed to improve academic language skills, including a library training exercise, "modeling" of the writing assignment, and drafting of subsections of the paper. This multistep neurophysiology project represents a significant commitment of time by both students and instructors, but produces a valuable finished product and ideally gives introductory students a positive first experience with science.

    O'Connell, S.; Ortiz, J.

    2004-12-01

    For the past 3 summers we have organized and evaluated 4 different, but related programs designed to introduce urban middle and high school students to the Earth Sciences through field and laboratory measurements of rivers. During the first summer (2002) two different programs were organized. Program one was a two-week, non-credit high school enrichment experience with the majority of the students coming from a science and math magnet school. Program two was a six-week program working with students from at risk-high schools. Students in this second program were paid and received one high school science credit. In both programs students measured water quality parameters, analyzed data and presented their results. All students from both programs were invited to participate in monthly field trips during the academic year. The third summer (2003) students who participated in the academic year program were invited to return to the program. They were hired for a two-week period to review what had been learned the previous summer and to teach the material to middle school students enrolled in another program. This provided them with an opportunity to mentor younger students. During the fourth summer (2004) we continued our work with the middle school program that we collaborated with in the previous year. We provided an earth science component to a four-week middle school summer enrichment program that focused on fish habitats. Students were taken in boats to learn about the Connecticut Riverbed. They collected grab samples of the sediment and imaged the bottom with a side-scan sonar and subbottom profiler. Conclusions: 1) Summer enrichment programs can have an impact on student interest in pursing additional learning about and careers in the earth sciences. 2) Most students thought the programs would help them to do better in math and science classes. 3)The most successful of our programs was the longer program, where students participated for two summers with monthly

    The Ultrasound Challenge was developed at The Ohio State University College of Medicine to introduce focused ultrasound to medical students. The goal was to develop experience in ultrasound through practice and competition. Initially this competition was held between Ohio State University College of Medicine students from years 1 through 4. The Ultrasound Challenge 2.0 was held in 2013. The event expanded on the previous structure by including students from the Wayne State University College of Medicine. The goal of this article is to describe our experiences with expansion of our interinstitutional ultrasound event. The challenge consisted of 6 stations: focused assessment with sonography for trauma, aortic ultrasound, cardiac ultrasound, pelvic ultrasound, musculoskeletal ultrasound, and vascular access. The participants were given a handbook outlining the expectations for each station ahead of time. Vascular access was graded in real time using the Brightness Mode Quality Ultrasound Imaging Examination Technique (B-QUIET) method. The remainder were timed, saved, and graded after the event by 3 independent faculty members using the B-QUIET method. The highest score with the fastest time was the winner. The Ultrasound Challenge 2.0 included 40 participants: 31 from The Ohio State University College of Medicine and 9 from the Wayne State University College of Medicine. The makeup of the winners in all categories consisted of 1 first-year medical student, 7 second-year medical students, 3 third-year medical students, and 10 fourth-year medical students. The Ultrasound Challenge 2.0 was a success for those who participated. It provided the first known interinstitutional medical student ultrasound competition. Students from both institutions were able to practice their image acquisition skills, demonstrate abilities in a competitive environment, and develop collegiality and teamwork. PMID:25425378

    2014-11-01

    Basic concepts concerning magnetic hysteresis are of vital importance in understanding magnetic materials. However, these concepts are often misinterpreted by many students and even textbooks. We summarize the most common misconceptions and present a new approach to help clarify these misconceptions and enhance students’ understanding of the hysteresis loop. In this approach, students are required to perform an experiment and plot the measured magnetization values and thereby calculated demagnetizing field, internal field, and magnetic induction as functions of the applied field point by point on the same graph. The concepts of the various coercivity, remanence, saturation magnetization, and saturation induction will not be introduced until this stage. By plotting this graph, students are able to interlink all the preceding concepts and intuitively visualize the underlying physical relations between them.

    Global Climate Change (GCC) is currently not part of the California Science Standards for 7th grade. Required course elements, however, such as the carbon cycle, photosynthesis, and cellular respiration could be linked to global climate change. Here we present a lesson plan developed in collaboration with scientists from Lawrence Livermore National Laboratory, to involve 7th grade students in monitoring of fossil fuel emissions in the Richmond/San Pablo area of California. -The lesson plan is a Greenhouse Gas/Global Climate Change Unit, with an embedded research project in which students will collect plant samples from various locals for analysis of 14C, to determine if there is a correlation between location and how much CO2 is coming from fossil fuel combustion. Main learning objectives are for students to: 1) understand how fossil fuel emissions impact the global carbon cycle, 2) understand how scientists estimate fossil CO2 emissions, and 3) engage in hypothesis development and testing. This project also engages students in active science learning and helps to develop responsibility, two key factors for adolescentsWe expect to see a correlation between proximity to freeways and levels of fossil fuel emissions. This unit will introduce important GCC concepts to students at a younger age, and increase their knowledge about fossil fuel emissions in their local environment, as well as the regional and global impacts of fossil emissions.

  16. Fostering climate dialogue by introducing students to uncertainty in decision-making

    Uncertainty is present in all fields of climate research, spanning from climate projections, to assessing regional impacts and vulnerabilities to adaptation policy and decision-making. The complex and interdisciplinary nature of climate information, however, makes the decision-making process challenging. This process is further hindered by a lack of institutionalized dialogue between climate researchers, decision-makers and user groups. Forums that facilitate such dialogue would allow these groups to actively engage with each other to improve decisions. In parallel, introducing students to these challenges is one way to foster such climate dialogue. We present the design and outcome of an innovative workshop-seminar series we convened at the University of Zurich to demonstrate the pedagogical importance of such forums. An initial two-day workshop brought together 50 participants, including bachelor, master and PhD students and academic staff, and nine speakers from academia, industry, government, and philanthropy. The main objectives were to provide participants with tools to communicate uncertainty in their current or future research projects, to foster exchange between practitioners, students and scientists from different backgrounds and finally to expose students to multidisciplinary collaborations and real-world problems involving decisions under uncertainty. An opinion survey conducted before and after the workshop enabled us to observe changes in participants' perspectives on what information and tools should be exchanged between researchers and decision-makers to better address uncertainty. Responses demonstrated a marked shift from a pre-workshop vertical conceptualization of researcher-user group interaction to a post-workshop horizontal mode: in the former, researchers were portrayed as bestowing data-based products to decision-makers, while in the latter, both sets of actors engaged in frequent communication, exchanging their needs and expertise.

  19. On to the 'rough ground': introducing doctoral students to philosophical perspectives on knowledge.

    PubMed

    Rehg, Ellen; SmithBattle, Lee

    2015-04-01

    Doctoral programmes in nursing are charged with developing the next generation of nurse scholars, scientists, and healthcare leaders. The American Association of Colleges of Nursing (AACN) endorses the inclusion of philosophy of science content in research-focused doctoral programmes. Because a philosophy course circumscribed to the natural or social sciences does not address the broad forms of knowledge that are relevant to nursing practice, we have developed and co-taught a course on the philosophy of knowledge that introduces students to competing claims regarding the nature of knowledge, truth, and rationality. In addressing broad themes related to science and knowledge of the body, health and illness, and ethics, the course equips students to tread the rough and shifting ground of nursing scholarship and practice. Providing doctoral students with this philosophical footing is intended to give future scholars, researchers, and healthcare leaders the intellectual skills to critically reflect on knowledge claims, to challenge the hegemony of science, and to recognize the disciplinary forms of knowledge that are left out or trivialized. Our pedagogical approach to knowledge development does not denigrate scientific knowledge, but elevates forms of inquiry and notions of clinical knowledge that are too often marginalized in doctoral education and the academy in general.

  3. Introducing a buddying scheme for first year pre-registration students.

    PubMed

    Campbell, Anne

    Student buddying schemes have been found to be helpful for a variety of different university students. This article describes a scheme where first year pre-registration child nursing students are buddied with second-year students, which was first initiated in the academic year 2012/2013. The first year students were aware that peer support was available but contact was only maintained by a minority of students. At present it is uncertain what impact the scheme has had on attrition figures, particularly in the first year. Initial evaluation indicates that students found the scheme helpful and would like it to continue to be available to first-year students. PMID:26559101

  4. Introducing chemical biology applications to introductory organic chemistry students using series of weekly assignments.

    PubMed

    Kanin, Maralee R; Pontrello, Jason K

    2016-01-01

    Calls to bring interdisciplinary content and examples into introductory science courses have increased, yet strategies that involve course restructuring often suffer from the need for a significant faculty commitment to motivate change. Minimizing the need for dramatic course reorganization, the structure, reactivity, and chemical biology applications of classes of biological monomers and polymers have been integrated into introductory organic chemistry courses through three series of semester-long weekly assignments that explored (a) Carbohydrates and Oligosaccharides, (b) Amino Acids, Peptides, and Proteins, and (c) Nucleosides, Nucleotides, and Nucleic Acids. Comparisons of unannounced pre- and post tests revealed improved understanding of a reaction introduced in the assignments, and course examinations evaluated cumulative assignment topics. Course surveys revealed that demonstrating biologically relevant applications consistently throughout the semesters enhanced student interest in the connection between basic organic chemistry content and its application to new and unfamiliar bio-related examples. Covering basic material related to these classes of molecules outside of the classroom opened lecture time to allow the instructor to further build on information developed through the weekly assignments, teaching advanced topics and applications typically not covered in an introductory organic chemistry lecture course. Assignments were implemented as homework, either with or without accompanying discussion, in both laboratory and lecture organic courses within the context of the existing course structures.

  11. Introducing Pre-university Students to Primary Scientific Literature Through Argumentation Analysis

    NASA Astrophysics Data System (ADS)

    Koeneman, Marcel; Goedhart, Martin; Ossevoort, Miriam

    2013-01-01

    Primary scientific literature is one of the most important means of communication in science, written for peers in the scientific community. Primary literature provides an authentic context for showing students how scientists support their claims. Several teaching strategies have been proposed using (adapted) scientific publications, some for secondary education, but none of these strategies focused specifically on scientific argumentation. The purpose of this study is to evaluate a strategy for teaching pre-university students to read unadapted primary scientific literature, translated into students' native language, based on a new argumentation analysis framework. This framework encompasses seven types of argumentative elements: motive, objective, main conclusion, implication, support, counterargument and refutation. During the intervention, students studied two research articles. We monitored students' reading comprehension and their opinion on the articles and activities. After the intervention, we measured students' ability to identify the argumentative elements in a third unadapted and translated research article. The presented framework enabled students to analyse the article by identifying the motive, objective, main conclusion and implication and part of the supports. Students stated that they found these activities useful. Most students understood the text on paragraph level and were able to read the article with some help for its vocabulary. We suggest that primary scientific literature has the potential to show students important aspects of the scientific process and to learn scientific vocabulary in an authentic context.

    2010-02-01

    An assignment incorporating active learning, computerized technology, and contact with RNs or Real Nurses was created to educate, enthuse, and heighten the awareness of nursing students about the world of nursing that exists beyond the classroom walls. Students gather information about an assigned field of nursing and share findings with classmates by giving clues about their mystery careers related to educational background, practice location, clientele, responsibilities, rewards, and challenges associated with the area of practice. Access to Web sites, RN e-mails, and guidelines are provided via an online Blackboard(®) learning system. Students benefit by gaining experience in the use of different types of computerized technology while being educated about the extensive career options available in nursing. The Career Clue assignment is a creative teaching strategy that has been used since 2003 and has consistently received positive feedback from students. PMID:19877569

    PubMed

    DeMatteo, Dale J; Reeves, Scott

    2013-01-01

    This paper explores the experiences of, and thoughts on, interprofessional learning and care of first year health science students at a large Canadian university within a broad socioeconomic context. We apply discourse analysis to survey data collected to evaluate an introductory interprofessional event involving first year students from a variety of health professions. Follow-up focus-group interviews were conducted to gain greater understanding of student issues and concerns emerging from the survey, providing a second source of data. A significant paper entitled, "Education, enterprise culture and the entrepreneurial self: A Foucauldian perspective" by Peters (2001) provides an historical and theoretical framework for this paper. Peters notes the changing nature of professionalism and global crises in public institutions under neoliberalism as governments divest themselves of social responsibility, shifting it onto individuals through increased privatization and focus on entrepreneurialism. In exploring the thoughts and experiences of students through the historical lens of a shifting professional discourse and changing cultural and political environment, a unique view of professionalism and this interprofessional project comes to light. Reflective of the paradigm shift that Peters documents, there was evidence of students "internalizing" responsibility for a sustainable health care system through acquisition of interprofessional knowledge and behaviours.

    2013-06-01

    Although there is a broad agreement among scientists and science educators that students should not only learn science, but also acquire some sense of its nature, it has been reported that undergraduate students possess an inadequate grasp of the nature of science (NOS). The study presented here examined the potential and effectiveness of Nobel Prize stories as a vehicle for teaching NOS. For this purpose, a 36-hour course, “Albert Einstein’s Nobel Prize and the Nature of Science,” was developed and conducted in Taiwan Normal University. Ten undergraduate physics students participated in the course. Analysis of the Views of Nature of Science questionnaires completed by the students before and after the course, as well as the students’ own presentations of Nobel Prize stories (with an emphasis on how NOS characteristics are reflected in the story), showed that the students who participated in the course enriched their views concerning all aspects of NOS. The paper concludes with some suggestions for applying the novel idea of using Nobel Prize stories in physics classrooms.

  15. Introducing Third-Year Chemistry Students to the Planning and Design of an Experimental Program

    NASA Astrophysics Data System (ADS)

    Dunn, Jeffrey G.; Phillips, David Norman; van Bronswijk, Wilhelm

    1997-10-01

    The design and planning of an experimental program is often an important aspect of the job description of recent graduate employees in chemical industry and time should therefore be devoted to this activity in an undergraduate course. This paper describes a pencil and paper activity which involves the design and planning of an experimental programme which may lead to the solution of the problem. These skills are an essential pre-requisite to any experimental activity. We provide the students with a list of problems similar to those that a new graduate could encounter on commencing employment in chemical industry. They are real problems, which the Inorganic Chemistry staff of the School have been previously asked to solve for local industry. A staff member acts as the "client", and the students is the "consultant". The aim is that by a series of interviews between the client and the consultant, the students can refine a vague problem statement into a quantitative statement, and then from this develop a proposal to investigate the problem in order to confirm the cause. This proposal is submitted to the client for assessment. The students are expected to arrange one meeting with the supervisor in each week. This activity is highly commended by the School of Applied Chemistry's Advisory Board, which is primarily comprised of industrial chemists.

    PubMed

    Allen, Peter J; Roberts, Lynne D; Baughman, Frank D; Loxton, Natalie J; Van Rooy, Dirk; Rock, Adam J; Finlay, James

    2016-01-01

    Although essential to professional competence in psychology, quantitative research methods are a known area of weakness for many undergraduate psychology students. Students find selecting appropriate statistical tests and procedures for different types of research questions, hypotheses and data types particularly challenging, and these skills are not often practiced in class. Decision trees (a type of graphic organizer) are known to facilitate this decision making process, but extant trees have a number of limitations. Furthermore, emerging research suggests that mobile technologies offer many possibilities for facilitating learning. It is within this context that we have developed StatHand, a free cross-platform application designed to support students' statistical decision making. Developed with the support of the Australian Government Office for Learning and Teaching, StatHand guides users through a series of simple, annotated questions to help them identify a statistical test or procedure appropriate to their circumstances. It further offers the guidance necessary to run these tests and procedures, then interpret and report their results. In this Technology Report we will overview the rationale behind StatHand, before describing the feature set of the application. We will then provide guidelines for integrating StatHand into the research methods curriculum, before concluding by outlining our road map for the ongoing development and evaluation of StatHand.

  16. Kate's Journey: Introducing Students to the Human Side of Aging Services and Supports.

    PubMed

    Brown, Pamela Pitman; Niles-Yokum, Kelly

    2016-01-01

    Although using novels to teach aging is not a new concept, teaching the human side of long-term services and supports from the perspective of the care recipient via novels has not been thoroughly explored. Literature often reflects societal norms and issues; thus, the use of a novel in the classroom allows for critical reflection and analysis of self and other, particularly when engaging students in aging concepts and experiences of growing old. This article describes the employment of Kate Quinton's Days (1984), a novel that brings into focus the important, and often forgotten, human side of aging services and supports. Additionally, the novel focuses on administrative and medical bureaucracy within the context of home health, and family dynamics that come into play with issues of aging and long-term care. Students may have had limited exposure to various aspects of aging and care that play out in the novel, and bringing the character Kate and her life story into the classroom allows for discussions that would not otherwise be as meaningful or instructive. The authors found that students related in important ways to Kate and went beyond the "system" to consider the lived experience of care and support as we age. PMID:27267464

  17. Integrating Seismology into the Physics Curriculum: An Opportunity to Introduce High-School Students to Scientific Research

    NASA Astrophysics Data System (ADS)

    Sayers, J.

    2002-12-01

    High school physics provides a natural vehicle for introducing seismology and geophysics concepts into the secondary science curriculum. Fundamental principles of mechanics and wave motion can be studied through investigation of the real-world phenomena of earthquakes and the seismic waves they generate. In turn, the excitement of a major earthquake and news media coverage stimulates student interest and involvement, especially if students are able to record the event. Too often, students' exposure to science has been confined to textbook work or "cookbook" lab exercises and they develop a very limited understanding of how science works. The National Science Standards, as well as many state standards, have emphasized the importance of hands-on inquiry-based activities, the use of real data and the introduction of research as fundamental to improving students' understanding of science. Students who run their own seismic station have the opportunity to experience the rewards and frustrations that can result from real scientific work. At Northview High School (Brazil, Indiana) we have installed a PEPP broadband seismometer in an external vault. Physics students are responsible for the day-to-day operation of the station. They download data and produce and post seismograms of earthquakes that have been recorded by the station and identified by the students. A hallway display case provides students, faculty and staff with a continuous (nearly) live display of the data being collected. The operation of the station has generated a great deal of student and community interest in the study of earthquakes. In this presentation, I will describe how seismology has been incorporated into the physics curriculum at Northview High School, and how our students have benefited from the opportunity to take part in hands-on scientific research. I will describe our participation in a regional seismic network through seismic data acquisition, data analysis using seismological software

  18. Introducing students to digital geological mapping: A workflow based on cheap hardware and free software

    NASA Astrophysics Data System (ADS)

    Vrabec, Marko; Dolžan, Erazem

    2016-04-01

    The undergraduate field course in Geological Mapping at the University of Ljubljana involves 20-40 students per year, which precludes the use of specialized rugged digital field equipment as the costs would be way beyond the capabilities of the Department. A different mapping area is selected each year with the aim to provide typical conditions that a professional geologist might encounter when doing fieldwork in Slovenia, which includes rugged relief, dense tree cover, and moderately-well- to poorly-exposed bedrock due to vegetation and urbanization. It is therefore mandatory that the digital tools and workflows are combined with classical methods of fieldwork, since, for example, full-time precise GNSS positioning is not viable under such circumstances. Additionally, due to the prevailing combination of complex geological structure with generally poor exposure, students cannot be expected to produce line (vector) maps of geological contacts on the go, so there is no need for such functionality in hardware and software that we use in the field. Our workflow therefore still relies on paper base maps, but is strongly complemented with digital tools to provide robust positioning, track recording, and acquisition of various point-based data. Primary field hardware are students' Android-based smartphones and optionally tablets. For our purposes, the built-in GNSS chips provide adequate positioning precision most of the time, particularly if they are GLONASS-capable. We use Oruxmaps, a powerful free offline map viewer for the Android platform, which facilitates the use of custom-made geopositioned maps. For digital base maps, which we prepare in free Windows QGIS software, we use scanned topographic maps provided by the National Geodetic Authority, but also other maps such as aerial imagery, processed Digital Elevation Models, scans of existing geological maps, etc. Point data, like important outcrop locations or structural measurements, are entered into Oruxmaps as

  2. Introducing the improved Heaviside approach to partial fraction decomposition to undergraduate students: results and implications from a pilot study

    NASA Astrophysics Data System (ADS)

    Man, Yiu-Kwong

    2012-10-01

    Partial fraction decomposition is a useful technique often taught at senior secondary or undergraduate levels to handle integrations, inverse Laplace transforms or linear ordinary differential equations, etc. In recent years, an improved Heaviside's approach to partial fraction decomposition was introduced and developed by the author. An important feature of this approach is that there is no need to solve a system of linear equations or to use differentiations to find the unknown coefficients of the partial fractions. In order to study its potential application in mathematics education at the undergraduate level, a pilot study of tryout at the Hong Kong Institute of Education has been conducted. The data are collected via quizzes, questionnaires and face-to-face interviews. In this article, the results and implications will be discussed. In general, according to the responses and feedbacks from the instructors and students concerned, the improved Heaviside approach is suitable to be introduced at the undergraduate level, as an alternative to the method of undetermined coefficients described in common undergraduate mathematics textbooks.

  7. Creating curricular change: needs in grades 8 12 earth science

    NASA Astrophysics Data System (ADS)

    The realization that we do not control nature is often associated with devastating loss of life and property. Apparently, humans do not learn from their mistakes, because human tragedies seem to happen repeatedly and minimal modification of human behavior appears to transpire. Because people do not understand the dynamic nature of Earth and Earth processes, specific education to understand and to comprehend the cause and effect of a dynamic earth is needed. The strong economic base and a high literacy rate within the USA should contribute to the ability of the K-12 educational system to create more appropriate human behavior and response to processes shaping Earth. Today major efforts are underway in government agencies, professional societies, universities and by individuals to change what and how students learn about the environment. Curricular reform has been established as new national standards for what students should learn in science in grades K-12. Just having standards, however, does not guarantee implementation, improved teaching by teachers, or increased understanding by students. Science faculties must accept the challenge to provide the pedagogical education for K-12 teachers; teachers must be trained and empowered to implement change; this change must ripple throughout the entire K-12 system. Workshops and innovative materials to support renovations in the curricula are essential to affect change. The World Wide Web will be a major help in information dissemination. However, for success to be achieved, local involvement is fundamental. People with expertise about Earth can have the greatest impact on effecting change by helping neighbors acquire knowledge of the dynamic environment of Earth. The same people (namely you) must become pro-active in K-12 education.

  9. Use of case studies to introduce undergraduate students to principles of food microbiology, molecular biology, and epidemiology of food-borne disease.

    PubMed

    Ponder, Monica A; Sumner, Susan

    2009-05-01

    Mock outbreaks of infectious disease offer the ability to introduce principles of food microbiology, ecology, and epidemiology to undergraduate students using an inquiry driven process. Students were presented with an epidemiological case study detailing patient history, clinical presentation, and foods recently consumed. The students then had to form hypotheses about the causative agents and attempt to identify the vehicle of transmission from foods their patient consumed. Students applied biochemical testing protocols to explore bacterial metabolism that are used to identify pathogens. After biochemically identifying their case's causative agent, the students were introduced to rapid methods that are used by health departments. Students extracted DNA, performed PCR reactions to amplify the 16s rDNA gene and identified it by comparing the PCR product sequence to a database using BLAST. Rapid methods, which do not employ time-consuming culturing methods, are increasingly being used; this exercise ensures that students have the technical skills necessary to compete in an increasingly technological global market.

    Bryant, Susan G; Benson, Kim H

    2015-01-01

    Learning experiences about domestic violence may not be readily available to nursing students at their traditional clinical sites. Faculty at an associate degree nursing program developed and implemented elder abuse and intimate partner violence simulation scenarios for a Health Systems Concepts course. Learning objectives focused on assessment, safety, communication, education, and legal responsibilities for nurses. After the simulation, students participated in debriefing, completed student evaluations, and responded to three questions about the experience in their reflective journals. Faculty and students expressed satisfaction with this method of learning about domestic violence. PMID:26753306

  11. Are Africans, Europeans, and Asians Different “Races”? A Guided-Inquiry Lab for Introducing Undergraduate Students to Genetic Diversity and Preparing Them to Study Natural Selection

    PubMed Central

    Kalinowski, Steven T.; Andrews, Tessa M.; Leonard, Mary J.; Snodgrass, Meagan

    2012-01-01

    Many students do not recognize that individual organisms within populations vary, and this may make it difficult for them to recognize the essential role variation plays in natural selection. Also, many students have weak scientific reasoning skills, and this makes it difficult for them to recognize misconceptions they might have. This paper describes a 2-h laboratory for college students that introduces them to genetic diversity and gives them practice using hypothetico-deductive reasoning. In brief, the lab presents students with DNA sequences from Africans, Europeans, and Asians, and asks students to determine whether people from each continent qualify as distinct “races.” Comparison of the DNA sequences shows that people on each continent are not more similar to one another than to people on other continents, and therefore do not qualify as distinct races. Ninety-four percent of our students reported that the laboratory was interesting, and 79% reported that it was a valuable learning experience. We developed and used a survey to measure the extent to which students recognized variation and its significance within populations and showed that the lab increased student awareness of variation. We also showed that the lab improved the ability of students to construct hypothetico-deductive arguments. PMID:22665587

    2015-01-01

    Medical students are attracted by the prospect of a meaningful addition to their clinical work. Engineering students are excited by a unique opportunity to learn directly alongside their medical student peers. For both, as well as the scientific community at large, the boutique program at the University of Southern California (USC) linking engineering and medical training at the graduate level is instructive of a new way of approaching engineering education that can potentially provide benefits to both students and society. Students who have grown up in an era of ?mass customization? in the retail and service industries can enjoy that same degree of flexibility also in the realm of education. At the same time, society gains engineers who have developed an increased empathy and awareness of the clinical contexts in which their innovations will be implemented. PMID:26583889

    2016-03-01

    Medical students must learn how to practice high-value, cost-conscious care. By modifying the traditional SOAP (Subjective-Objective-Assessment-Plan) presentation to include a discussion of value (SOAP-V), we developed a cognitive forcing function designed to promote discussion of high-value, cost-conscious care during patient delivery. The SOAP-V model prompts the student to consider (1) the evidence that supports a test or treatment, (2) the patient's preferences and values, and (3) the financial cost of a test or treatment compared to alternatives. Students report their findings to their teams during patient care rounds. This tool has been successfully used at 3 medical schools. Preliminary results find that students who have been trained in SOAP-V feel more empowered to address the economic healthcare crisis, are more comfortable in initiating discussions about value, and are more likely to consider potential costs to the healthcare system.

    2015-04-01

    One important task for the librarians at Physics and Astronomy Library at Lund University is to teach the students about the library and its resources. The traditional lectures and tours of the library just weren't working. The library competes with many other introductory activities, such as general orientation, and social events. The aim of the Treasure Hunt is to present the library in a useful and amusing way for new students at the start of their studies. Divided into small groups, the students carry out various tasks at stations in the participating libraries. The hunt takes about two hours and a treasure (a goody bag) waits for them at the end. The evaluations show that the treasure hunt is highly appreciated by the students. They become familiar with the librarians and get to know essential aspects of the library resources. The treasure hunt is important in the students' later studies as it paves the way for further development of their information retrieval skills. A crucial factor to success of the Treasure Hunt is the cooperation of committed teachers. A challenge for the future is to have the Treasure Hunt integrated in all courses as a compulsory element.

  4. Introducing the Importance of Scientific Methods and Tools to Students Using Real Data and Inquiry Based Teaching.

    NASA Astrophysics Data System (ADS)

    Kaluzny, R.; McKinely, J. P.

    2007-12-01

    The National Science Education Teaching Standard states that teachers should "select teaching and assessment strategies that support the development of student understanding and nurture a community of science learners." The combination of scientific inquiry with 'real' data in the classroom would meet this standard and improve teaching methods, providing the scaffolding necessary for inquiry-based learning. The introduction to and use of real scientific data by students at a primary or secondary level would require from the teacher careful preparation and a detailed understanding of the material presented, but could improve the students' learning experience and increase the level of interest in scientific careers. This poster presents an example of an inquiry- based lesson driven by real scientific data. In the lesson, students were shown scanning electron micrographs of natural objects, such as flower pollen and mineral samples, and were allowed to examine the actual objects from which the micrographs were taken. Through guided discussion and conjecture, the relationship between the microscale features and the macroscale objects was explored. The students were prompted to explain the functional significance of the microscale features, e.g., the reason for the ridges on the surface of the pollen, and allowed to develop hypotheses to evaluate against the objects at hand. The students were encouraged to reach conclusions, and these conclusions were not evaluated to be correct or incorrect; the teacher's role was to facilitate observation and reasoning. The discussion about features apparent in the images but not in the actual samples provided an introduction to the importance of scientific methods and tools in many modern occupations and research areas. Using micrographs to show students an application of multi-scale images in the real world allowed them to have experience with real data and also allowed them to learn in a more hands-on and less controlled

    PubMed

    Rega, Paul; Bork, Christopher; Chen, Yixing; Woodson, Donna; Hogue, Patricia; Batten, Susan

    2010-01-01

    Currently, the H1N1 pandemic does not approach the worst-case scenarios that have been predicted by the Centers for Disease Control and Prevention and the World Health Organization. Nevertheless, its impact, fueled by its predilection for nontraditional victims, assorted governmental miscalculations, and journalistic hyperbole, has led to an environment of both fear and skepticism. In this environment, the healthcare infrastructure must sift through relevant data, set aside political rhetoric, weigh the risk-benefit ratio of health-related mandates and recommendations, interact with diverse agencies and departments, and still attend to the medical, psychological, and educational needs of its patients and the community at large. Despite the challenges presented by the H1N1 pandemic, there is also an opportunity for expanded interdisciplinary education. Recent and past events, here and abroad, have demonstrated that in times of great healthcare need, professional students, through either volunteerism or impressments, have been an important asset in disaster medicine and mass gatherings. The current H1N1 situation affords healthcare educators an opportunity to expose the current generation of students to disaster medicine and management of care for aggregates and populations. This educational motive is reinforced by the students' own altruistic desire to not only volunteer in a pandemic but also to act on the belief that it is their obligation. Therefore, the purpose of this article is to describe the preparedness and response roles of healthcare students and their faculty at a major university during the H1N1 crisis as an introduction to the interdisciplinary approach to disaster medicine and mass gatherings.

    Correia, Paulo R. M.; Torres, Bayardo B.

    2007-12-01

    The success of teaching molecular and atomic phenomena depends on the didactical strategy and the media selection adopted, in consideration of the level of abstraction of the subject to be taught and the students' capability to deal with abstract operations. Dale's cone of experience was employed to plan three 50-minute classes to discuss protein denaturation from a chemical point of view. Only low abstraction level activities were selected: (i) two demonstrations showing the denaturation of albumin by heating and by changing the solvent, (ii) the assembly of a macroscopic model representing the protein molecule, and (iii) a role-play for simulating glucagon synthesis. A student-centered approach and collaborative learning were used throughout the classes. The use of macroscopic models is a powerful didactical strategy to represent molecular and atomic events. They can convert microscopic entities into touchable objects, reducing the abstraction level required to discuss chemistry with high school students. Thus, interesting topics involving molecules and their behavior can take place efficiently when mediated by concrete experiences.

    Multiple-choice question (MCQ) examinations are increasingly used as the assessment method of theoretical knowledge in large class-size modules in many life science degrees. MCQ-tests can be used to objectively measure factual knowledge, ability and high-level learning outcomes, but may also introduce gender bias in performance dependent on topic, instruction, scoring and difficulty. The 'Single Answer' (SA) test is often used in which students choose one correct answer, in which they are unable to demonstrate partial knowledge. Negatively marking eliminates the chance element of guessing but may be considered unfair. Elimination testing (ET) is an alternative form of MCQ, which discriminates between all levels of knowledge, while rewarding demonstration of partial knowledge. Comparisons of performance and gender bias in negatively marked SA and ET tests have not yet been performed in the life sciences. Our results show that life science students were significantly advantaged by answering the MCQ test in elimination format compared to single answer format under negative marking conditions by rewarding partial knowledge of topics. Importantly, we found no significant difference in performance between genders in either cohort for either MCQ test under negative marking conditions. Surveys showed that students generally preferred ET-style MCQ testing over SA-style testing. Students reported feeling more relaxed taking ET MCQ and more stressed when sitting SA tests, while disagreeing with being distracted by thinking about best tactics for scoring high. Students agreed ET testing improved their critical thinking skills. We conclude that appropriately-designed MCQ tests do not systematically discriminate between genders. We recommend careful consideration in choosing the type of MCQ test, and propose to apply negative scoring conditions to each test type to avoid the introduction of gender bias. The student experience could be improved through the incorporation of the

Our results show that life science students were significantly advantaged by answering the MCQ test in elimination format compared to single answer format under negative marking conditions by rewarding partial knowledge of topics. Importantly, we found no significant difference in performance between genders in either cohort for either MCQ test under negative marking conditions. Surveys showed that students generally preferred ET-style MCQ testing over SA-style testing. Students reported feeling more relaxed taking ET MCQ and more stressed when sitting SA tests, while disagreeing with being distracted by thinking about best tactics for scoring high. Students agreed ET testing improved their critical thinking skills. We conclude that appropriately-designed MCQ tests do not systematically discriminate between genders. We recommend careful consideration in choosing the type of MCQ test, and propose to apply negative scoring conditions to each test type to avoid the introduction of gender bias. The student experience could be improved through the incorporation of

    1980-01-01

    The absolute intensities of the 8-12 micron bands from Freon 11 (CFCl3) were measured at temperatures of 294 and 216 K. Intensities of the bands centered at 798, 847, 934, and 1082 per cm are all observed to depend on temperature. The temperature dependence for the 847 and 1082 per cm fundamental regions is attributed to underlying hot bands; for the nu2 + nu5 combination band (934 per cm), the observed temperature dependence is in close agreement with theoretical prediction. The implication of these results on atmospheric IR remote-sensing is briefly discussed.

    2012-01-01

    The prevalence of DFNA8/DFNA12 (DFNA8/12), a type of autosomal dominant non-syndromic hearing loss (ADNSHL), is unknown as comprehensive population-based genetic screening has not been conducted. We therefore completed unbiased screening for TECTA mutations in a Spanish cohort of 372 probands from ADNSHL families. Three additional families (Spanish, Belgian and English) known to be linked to DFNA8/12 were also included in the screening. In an additional cohort of 835 American ADNSHL families, we preselected 73 probands for TECTA screening based on audiometric data. In aggregate, we identified 23 TECTA mutations in this process. Remarkably 20 of these mutations are novel, more than doubling the number of reported TECTA ADNSHL mutations from 13 to 33. Mutations lie in all domains of the α-tectorin protein, including those for the first time identified in the entactin domain, the vWFD1, vWFD2 and vWFD3 repeats, and the D1-D2 and TIL2 connectors. While the majority are private mutations, four of them – p.Cys1036Tyr, p.Cys1837Gly, p.Thr1866Met and p.Arg1890Cys – were observed in more than one unrelated family. For two of these mutations founder effects were also confirmed. Our data validate previously observed genotype-phenotype correlations in DFNA8/12 and introduce new correlations. Specifically, mutations in the N-terminal region of α-tectorin (entactin domain, vWFD1 and vWFD2) lead to mid frequency NSHL, a phenotype previously associated only with mutations in the ZP domain. Collectively, our results indicate that DFNA8/12 hearing loss is a frequent type of ADNSHL. PMID:21520338

    Resendes, Karen K

    2015-01-01

    Incorporating scientific literacy into inquiry driven research is one of the most effective mechanisms for developing an undergraduate student's strength in writing. Additionally, discovery-based laboratories help develop students who approach science as critical thinkers. Thus, a three-week laboratory module for an introductory cell and molecular biology course that couples inquiry-based experimental design with extensive scientific writing was designed at Westminster College to expose first year students to these concepts early in their undergraduate career. In the module students used scientific literature to design and then implement an experiment on the effect of cellular stress on protein expression in HeLa cells. In parallel the students developed a research paper in the style of the undergraduate journal BIOS to report their results. HeLa cells were used to integrate the research experience with the Westminster College "Next Chapter" first year program, in which the students explored the historical relevance of HeLa cells from a sociological perspective through reading The Immortal Life of Henrietta Lacks by Rebecca Skloot. In this report I detail the design, delivery, student learning outcomes, and assessment of this module, and while this exercise was designed for an introductory course at a small primarily undergraduate institution, suggestions for modifications at larger universities or for upper division courses are included. Finally, based on student outcomes suggestions are provided for improving the module to enhance the link between teaching students skills in experimental design and execution with developing student skills in information literacy and writing.

    2015-10-01

    The aim of this study was to determine whether e-learning as a new teaching concept was acceptable for second-year undergraduates and to compare attitudes and exam results of students who followed electronic compared with classroom seminars. The electronic seminars (e-seminars) were developed several months prior to start of the epidemiology course for second-year students at the Faculty of Medicine, University of Belgrade. The students who applied for e-seminars accessed their content during summer semester (February-May) 2014. E-seminars were set according to the existing topics in practical workbook and designed using Moodle, a free, open-source, personal home page web application for producing modular internet-based courses. To evaluate the motives for enrollment and satisfaction with seminars, two surveys (pre- and post-course) were administered. Students' exam grades were registered over 4 exam sessions (June-October 2014) and compared according to seminar program. Out of 516 students in the second year, 60 (11.6 %) applied for e-seminars (mean age 21 years). Students considered the reason "It's easier to do assignments from home" as the strongest motive to participate. When compared to classroom seminars, students in e-seminars had significantly more fun (p = 0.003), thought that e-seminars were better mode to learn epidemiology (p = 0.030) and would recommend them to other colleagues (p = 0.001). There was no significant difference in average grade received at the oral exam in epidemiology (t = 0.071, p = 0.944). E-seminars in undergraduate epidemiology course add a novel, easy-to-follow and amusing mode of learning. Based on this pilot study, e-seminars in epidemiology will be available for next generations of students, while further improvement of e-seminars could include expansion of seminar syllabus and development of discussion fora.

    Land surface window emissivity is a key parameter for estimating the longwave radiative budget. The combined radiative transfer model (RM) with neural network (NN) algorithm is utilized to directly estimate the window (8-12 um) emissivity from the brightness temperature of the Advanced Spaceborne Thermal Emission and Reflection Radiometer (ASTER) with 90 m spatial resolution. Although the estimation accuracy is very high when the broadband emissivity is estimated from AST05 (ASTER Standard Data Product) by using regression method, the accuracy of AST05 is about ± 0.015 for 86 spectra which is determined by the atmosphere correction for ASTER 1B data. The MODTRAN 4 is used to simulate the process of radiance transfer, and the broadband emissivity is directly estimated from the brightness temperature of ASTER 1B data at satellite. The comparison analysis indicates that the RM-NN is more competent to estimate broadband emissivity than other method when the brightness temperatures of band 11, 12, 13, 14 are made as input nodes of dynamic neural network. The estimation average accuracy is about 0.009, and the estimation results are not sensitive to instrument noise. The RM-NN is applied to extract broadband emissivity from an image of ASTER 1B data in China, and the comparison against a classification based multiple bands with 15 m spatial resolution shows that the estimation results from RM-NN are very good.

  12. Introducing an online community into a clinical education setting: a pilot study of student and staff engagement and outcomes using blended learning

    PubMed Central

    2010-01-01

    Background There are growing reasons to use both information and communication functions of learning technologies as part of clinical education, but the literature offers few accounts of such implementations or evaluations of their impact. This paper details the process of implementing a blend of online and face-to-face learning and teaching in a clinical education setting and it reports on the educational impact of this innovation. Methods This study designed an online community to complement a series of on-site workshops and monitored its use over a semester. Quantitative and qualitative data recording 43 final-year medical students' and 13 clinical educators' experiences with this blended approach to learning and teaching were analysed using access, adoption and quality criteria as measures of impact. Results The introduction of the online community produced high student ratings of the quality of learning and teaching and it produced student academic results that were equivalent to those from face-to-face-only learning and teaching. Staff had mixed views about using blended learning. Conclusions Projects such as this take skilled effort and time. Strong incentives are required to encourage clinical staff and students to use a new mode of communication. A more synchronous or multi-channel communication feedback system might stimulate increased adoption. Cultural change in clinical teaching is also required before clinical education can benefit more widely from initiatives such as this. PMID:20100354

    PubMed

    Livneh, A; Preud'Homme, J L; Solomon, A; Diamond, B

    1987-12-01

    The 8.12 idiotype defines a population of anti-DNA antibodies present in the serum of patients with systemic lupus erythematosus. As part of our studies to elucidate the genetic origin and structural features of anti-DNA antibodies, we examined monoclonal immunoglobulin (Ig)-containing sera from 706 patients for expression of the 8.12 idiotype. We found 41 such sera to have significant 8.12 reactivity (greater than 4 SD above the mean of normal controls) and demonstrated that in 24 of these sera (8 IgM, 14 IgG, and 2 IgA) this reactivity could be localized to the monoclonal protein. In addition, 12 of the 8.12-reactive monoclonal Ig (11 IgG and 1 IgA) bind dsDNA. In the other 17 sera, the 8.12 reactivity could be attributed to polyclonal antibody. These findings provide further evidence that the serum monoclonal Ig frequently express the antigenic and idiotypic reactivities of autoantibodies. Furthermore, these data support the contention that anti-DNA specificity may result from somatic diversification of germ-line Ig gene sequences. PMID:3119715

    Aim: In order to better prepare future health care professionals for interprofessional cooperation, interprofessional learning sessions for medical students and physiotherapy apprentices were developed at the University Medical Centre Mannheim, Germany. The experience gained from designing, implementing and evaluating these learning sessions is presented and discussed. Method: A total of 265 medical students and 43 physiotherapy apprentices attended five interprofessional learning sessions. Of these, 87-100% responded to closed and open-ended questions on a self-developed questionnaire (24 items). The responses regarding self-reported learning gains, benefit, motivation and satisfaction with the sessions were analyzed separately by professions. Results: The learning sessions were well received by both groups. More than 75% of all participants were of the opinion that they could not have learned the new material in a better way. Significant differences between the medical students and the physiotherapy apprentices were mainly found with regard to perceived learning gains, which physiotherapy apprentices reported as being lower. Positive aspects of interprofessionalism were most often emphasized in the responses to the open-ended questions. Most frequently criticized were organizational aspects and a lack of perceived learning gains. Conclusion: The introduction of interprofessional learning entails great effort in terms of organizational and administrative challenges. However, the project is considered worthwhile because the interprofessional aspects of the learning sessions were indeed valued by the participants. Permanently including and expanding interprofessional learning in the curricula of both professions longitudinally is therefore something to strive for. PMID:27280142

    4,10-Dinitro-2,6,8,12-tetraoxa-4,10-diazatetracyclo[5.5.0.05,903,11]dodecane (TEX) was obtained by nitrolysis of 1,4-diformyl-2,3,5,6-tetrahydroxypiperazine reaction using a mixture of fuming nitric acid and concentrated sulfuric acid. The optimal process temperature was 54-56°C. The yield of the synthesis depends inter alia on the rate the reactants are introduced into the reaction medium and on the time of conditioning of the reaction mixture. A maximal yield of ca. 40% was achieved at the reactant addition time of 2 h and conditioning time of 2 h. None of the other nitrating mixtures examined proved superior to the conventional nitrating mixture. The product was examined by high-performance liquid chromatography (HPLC), nuclear magnetic resonance (NMR), Fourier transform infrared (FTIR), and differential scanning calorimetry (DSC) techniques and the results are reported.

    Most students know that planetary orbits, including Earth's, are elliptical; that is Kepler's first law, and it is found in many science textbooks. But quite a few are mistaken about the details, thinking that the orbit is very eccentric, or that this effect is somehow responsible for the seasons. In fact, the Earth's orbital eccentricity is small, and its only effect on the seasons is their unequal durations. Here I show a pleasant way to guide students to the actual value of Earth's orbital eccentricity, starting from the durations of the four seasons. The date of perihelion is also found.

    2009-01-01

    Channel Access Markup Language (CAML) is a XML based markup language and implementation for displaying EPICS channel access controls within a web browser. The CAML II project expanded upon the work of CAML I adding more features and greater integration with other web technologies. The most dramatic new feature introduced in CAML II is the introduction of a namespace so CAML controls can be embedded within XHTML documents. A repetition template with macro substitution allows for rapid coding of arbitrary XHTML repetitions. Enhancements have been made to several controls including more powerful plotting options. Advanced formatting options were introduced for text controls. Virtual process variables allow for custom calculations. An EDL to CAML translator eases the transition from EDM screens to CAML pages.

  14. Introducing the Moon's Orbital Eccentricity

    NASA Astrophysics Data System (ADS)

    Oostra, Benjamin

    2014-11-01

    I present a novel way to introduce the lunar orbital eccentricity in introductory astronomy courses. The Moon is perhaps the clearest illustration of the general orbital elements such as inclination, ascending node, eccentricity, perigee, and so on. Furthermore, I like the students to discover astronomical phenomena for themselves, by means of a guided exercise, rather than just telling them the facts.1 The inclination and nodes may be found by direct observation, monitoring carefully the position of the Moon among the stars. Even the regression of the nodes may be discovered in this way2 To find the eccentricity from students' observations is also possible,3 but that requires considerable time and effort. if a whole class should discover it in a short time, here is a method more suitable for a one-day class or home assignment. The level I aim at is, more or less, advanced high school or first-year college students. I assume them to be acquainted with celestial coordinates and the lunar phases, and to be able to use algebra and trigonometry.

    The tiny town of Niangua, Missouri, made national headlines in 2008 when a rare cluster of winter tornadoes tore across the state on an unseasonably warm January night. The twisters killed a Niangua woman in her trailer home and destroyed numerous other structures. News photos of the trailer debris were a sobering reminder of the vulnerability of…

  18. Introducing electromagnetic field momentum

    NASA Astrophysics Data System (ADS)

    Yu-Kuang Hu, Ben

    2012-07-01

    I describe an elementary way of introducing electromagnetic field momentum. By considering a system of a long solenoid and line charge, the dependence of the field momentum on the electric and magnetic fields can be deduced. I obtain the electromagnetic angular momentum for a point charge and magnetic monopole pair partially through dimensional analysis and without using vector calculus identities or the need to evaluate integrals. I use this result to show that linear and angular momenta are conserved for a charge in the presence of a magnetic dipole when the dipole strength is changed.

    2013-03-01

    The Cherenkov Telescope Array (CTA) is a new observatory for very high-energy (VHE) gamma rays. CTA has ambitions science goals, for which it is necessary to achieve full-sky coverage, to improve the sensitivity by about an order of magnitude, to span about four decades of energy, from a few tens of GeV to above 100 TeV with enhanced angular and energy resolutions over existing VHE gamma-ray observatories. An international collaboration has formed with more than 1000 members from 27 countries in Europe, Asia, Africa and North and South America. In 2010 the CTA Consortium completed a Design Study and started a three-year Preparatory Phase which leads to production readiness of CTA in 2014. In this paper we introduce the science goals and the concept of CTA, and provide an overview of the project.

  1. Excellent results of HA coating on a grit-blasted stem: 245 patients followed for 8-12 years.

    We report the outcome of a grit-blasted titanium stem designed for press-fit insertion and entirely plasma sprayed with HA. During the years 1988-1993, we performed 323 primary total hip replacements in 276 patients (189 women) with a HA-coated prosthesis. Their mean age was 48 (15-79) years. During the follow-up, 12 patients died. 19 other patients did not attend the follow-up examination, but had no major symptoms according to telephone interviews and written replies. Thus, 245 patients (291 hips) were followed for a mean of 10 (8-12) years with radiographic and clinical examinations. Only 1 stem was revised due to mechanical failure. None were revised because of infection. Osteolysis was significantly associated with wear, and wear was significantly associated with the size of the femoral head. We found a small amount of proximal bone loss (37/291) and a low incidence of distal hypertrophy of the bone (23/291). These observations indicate an essentially physiological weight distribution from the stem to the femoral bone. The changes in the bone confirmed that the femoral component was well fixed in asymptomatic patients. To conclude, we found excellent 8-12-year results with a fully HA-coated femoral prosthesis designed for press-fit insertion. PMID:12807319

    ADS Labs is a platform that ADS is introducing in order to test and receive feedback from the community on new technologies and prototype services. Currently, ADS Labs features a new interface for abstract searches, faceted filtering of results, visualization of co-authorship networks, article-level recommendations, and a full-text search service. The streamlined abstract search interface provides a simple, one-box search with options for ranking results based on a paper relevancy, freshness, number of citations, and downloads. In addition, it provides advanced rankings based on collaborative filtering techniques. The faceted filtering interface allows users to narrow search results based on a particular property or set of properties ("facets"), allowing users to manage large lists and explore the relationship between them. For any set or sub-set of records, the co-authorship network can be visualized in an interactive way, offering a view of the distribution of contributors and their inter-relationships. This provides an immediate way to detect groups and collaborations involved in a particular research field. For a majority of papers in Astronomy, our new interface will provide a list of related articles of potential interest. The recommendations are based on a number of factors, including text similarity, citations, and co-readership information. The new full-text search interface allows users to find all instances of particular words or phrases in the body of the articles in our full-text archive. This includes all of the scanned literature in ADS as well as a select portion of the current astronomical literature, including ApJ, ApJS, AJ, MNRAS, PASP, A&A, and soon additional content from Springer journals. Fulltext search results include a list of the matching papers as well as a list of "snippets" of text highlighting the context in which the search terms were found. ADS Labs is available at http://adslabs.org

    The Atmospheric Visualization Collection is a digital library collection, a section in the NSF's National Science Digital Library. The collection has two essential components. The first is an archive of images based on data from the Atmospheric Radiation Measurement (ARM) program. The second is a collection of educational material based on atmospheric science concepts that use these data images. The data image archive focuses on the ARM Southern Great Plains (SGP) site, which has the largest collection of ground-based remote-sensing atmospheric instruments. Our visualization tools are automated to create the data images for both archival and real-time uses. ARM instrument mentors and ARM scientist as well as other scientists involved in campaigns at the ARM SGP site review our visualization work for scientific quality. While the archive of weather images was initially created for scientists, collaboration with teachers has identified many of the barriers to educational use. This revealed the need for more educationally friendly interfaces into our weather images and the need for greater documentation. One of the results is our geophysical focus area interface, allowing teachers and students to access these data images. The visualization tools used to produce these data images are available through an open source repository. Testing with undergraduate students has demonstrated the usability of these tools with data from the ARM Archive for class projects. While the task of reviewing and improving user interfaces continues, we have reached a stage where educators and students can easily access our atmospheric data images. An initial set of peer reviewed lesson plans based on these data images has been the basis for workshops to introduce teachers to the AVC. To further involve these teachers a Lesson Plan Sandbox. The Lesson Plan Sandbox allows teachers to submit their lesson plans to share with others, to review lesson plans submitted by other teachers, and to add

  9. Rheological properties in discotic liquid crystalline phases of 2,3,7,8,12,13-hexa(n-tetradecanoyloxy)truxene.

    PubMed

    Negita, Keishi; Kawano, Chiharu; Moriya, Keiichi

    2004-08-01

    Measurements of rheological properties, including the electrorheological effect, are made in liquid crystalline phases, discotic nematic (ND) and discotic disordered rectangular columnar (Drd) phases, of 2,3,7,8,12,13-hexa(n-tetradecanoyloxy)truxene. It is found that the fluidity of the ND phase is Newtonian and an application of high electric field perpendicular to the flow direction (velocity gradient direction) causes a decrease of the viscosity. These results indicate that a flow alignment of the director occurs with its orientation near the velocity gradient direction and the signs of the Leslie coefficients alpha2 and alpha3 are positive. From the temperature dependence of alpha2, instability of the flow alignment structure in ND and Drd phases is also discussed. PMID:15447504

    1995-11-01

    Hg1-xCdxTe (x approximately equal to 0.205, 0.27) 64 photodiode hybrid linear arrays for spectral regions (lambda) approximately equal to 3 - 5 and 8 - 12 micrometer have been designed. The p+-n-diodes were As-diffused n-type indium doped single crystals (n approximately equal to (2 - 5) 1015 cm-3) delineated with standard wet photolithography technique. Surface leakage current at T equals 80 K seems to be the dominant current mechanism for the diodes with no passivation coating. At higher temperatures the generation-recombination mechanism was found to be the principal one. Diodes had mean detectivity values D* (10.5 micrometer, 500, 1) approximately equal to 2 1010 and D* (6.0 micrometer, 500, 1) approximately equal to 6 1010 cm Hz1/2W-1 at 80 K. The arrays were interconnected to silicon direct injection readout devices with CCD multiplexers which consist of input circuits, shift register and output circuits. The dynamical range was estimated to be of the order of 60 dB at T equals 80 K. The two-phase p-channel CCD shift register was designed with clock frequency operation $less than or equal to 5 MHz. Transfer efficiency without fat zero was 0.99985 at 1.0 MHz frequency. The control interface based on 16-channel, 10-bit A/D converter was developed for computer data recording and signal processing.

    2009-01-01

    Objectives To evaluate how involvement in life situations (participation) in children with cerebral palsy varies with type and severity of impairment and to investigate geographical variation in participation. Design Cross sectional study. Trained interviewers visited parents of children with cerebral palsy; multilevel multivariable regression related participation to impairments, pain, and sociodemographic characteristics. Setting Eight European regions with population registers of children with cerebral palsy; one further region recruited children from multiple sources. Participants 1174 children aged 8-12 with cerebral palsy randomly selected from the population registers, 743 (63%) joined in the study; the further region recruited 75 children. Main outcome measure Children’s participation assessed by the Life-H questionnaire covering 10 main areas of daily life. Scoring ignored adaptations or assistance required for participation. Results Children with pain and those with more severely impaired walking, fine motor skills, communication, and intellectual abilities had lower participation across most domains. Type of cerebral palsy and problems with feeding and vision were associated with lower participation for specific domains, but the sociodemographic factors examined were not. Impairment and pain accounted for up to a sixth of the variation in participation. Participation on all domains varied substantially between regions: children in east Denmark had consistently higher participation than children in other regions. For most participation domains, about a third of the unexplained variation could be ascribed to variation between regions and about two thirds to variation between individuals. Conclusions Participation in children with cerebral palsy should be assessed in clinical practice to guide intervention and assess its effect. Pain should be carefully assessed. Some European countries facilitate participation better than others, implying some countries

  15. Hydrogen bond network fluctuations in small (H2O)n clusters (n=8-12-24)

    NASA Astrophysics Data System (ADS)

    Masella, Michel; Flament, Jean-Pierre

    1999-09-01

    Molecular dynamic studies of three (H2O)n clusters (n=8-12-24) were performed using our recently developed many-body model TCPE [J. Chem. Phys. 107, 9105 (1997)] in the microcanonical ensemble. The trajectories were analyzed using a new structural local index derived from one of the many-body energetic term of TCPE. In the energy domain where the clusters are in a liquidlike state, a dynamical equilibrium is theoretically predicted to exist among molecules in the PHB1 and the PHB2 state (i.e., among molecules which one of their protons is involved in one hydrogen bond, the PHB1 state, and molecules which both of their protons are involved in two hydrogen bonds, the PHB2 state). The enthalpy and entropy changes corresponding to that equilibrium for the three clusters range from 0.75 to 1.10 kcal mol-1 and from -7 to -3.8 cal mol-1 K-1. Such an equilibrium between two species of hydrogen bonded molecules could be related to that experimentally observed in the case of liquid water at ambient conditions. In particular, the entropy changes corresponding to PHB2/PHB1 equilibrium in the case of the three clusters are very close to those experimentally reported for liquid water (about 6.6±0.5 cal mol-1 K-1), suggesting that the equilibrium observed in the case of liquid water could correspond to a PHB2/PHB1 equilibrium. The analysis of hydrogen bond networks in terms of PHBm states appears thus to be an encouraging way in characterising the dynamical properties of water systems.

  16. The validation and comparison of the GOCI aerosol optical thickness products: a case study of Tianjin 8.12

    NASA Astrophysics Data System (ADS)

    Yao, Lingling; Zhang, Xiaoyu; Yu, Hui; Jiang, Binbin

    2016-01-01

    COMSGOCI (Geostationary Ocean Color Imager) is the first geostationary ocean color satellite in the world launched by South Korea in June 2010, which includes eight bands from the visible to the infrared band. GOCI aerosol optical thickness (AOT) at 555nm was retrieved by atmospheric radiative transfer model based on two-stream approximation algorithm. Due to GOCI without near infrared band and has a high solar elevation angle, solar zenith angle must be recalibrated to solve the earth system albedo, and the surface reflectance solved by quack atmospheric correction and recalculated backward scatter coefficient. Evaluation of GOCIAOT with AERONET measurements showed that the average error becomes 0.107 from the original 0.393, that means GOCI aerosol optical thickness can be more accurately with the advanced two-stream approximation. Taking the eastern China in 3 and 4 December 2013 for example, comparing the GOCIAOT at 555nm, MODISAOT retrievals at 550nm, NPPAOT at 550nm and AERONET data products indicated that: take the AERONET data as reference, the error of three kinds of satellite data can be ordered as following: MODISAOT< GOCIAOT< NPPAOT and the GOCI-MODIS shows a bias of 0.02917 with the GOCI-NPP. GOCIAOT is 0.05714 generally bigger than that of MODISAOT. NPP-GOCI deviation is 0.10253. The deficiency of MODIS is its low spatial resolution and the high concentration of AOT will be mistaken for a cloud area. However, GOCI can well reflect the concentration and distribution of aerosols. Therefore, GOGI can provide real-time dynamic monitoring on China Eastern atmospheric environment and the accurate time event information of haze for each process can be obtained. Finally, applied GOCI to the "8.12 Tianjin bombings" and to monitor the migration and dispersion of pollutant.

  18. Atwood's machine as a tool to introduce variable mass systems

    NASA Astrophysics Data System (ADS)

    de Sousa, Célia A.

    2012-03-01

    This article discusses an instructional strategy which explores eventual similarities and/or analogies between familiar problems and more sophisticated systems. In this context, the Atwood's machine problem is used to introduce students to more complex problems involving ropes and chains. The methodology proposed helps students to develop the ability needed to apply relevant concepts in situations not previously encountered. The pedagogical advantages are relevant for both secondary and high school students, showing that, through adequate examples, the question of the validity of Newton's second law may even be introduced to introductory level students.

    Kourkoumelis, C.; Vourakis, S.

    2015-05-01

    Recent activities, towards the goal of introducing High Energy Physics in the school class, are reviewed. The most efficient method is a half or a full day workshop where the students are introduced to one of the large LHC experiments, follow a "virtual visit" to the experiment's Control Room and perform an interactive analysis of real data. Science cafes and visits to the CERN expositions are also very helpful, provided that the tours/discussions are led by an active scientist and/or a trained teacher. Several EU outreach projects provide databases rich with education scenaria and data analysis tools ready to be used by the teachers in order to bridge the gap between modern research and technology and school education.

  12. Introducing Stereochemistry to Non-science Majors

    NASA Astrophysics Data System (ADS)

    Luján-Upton, Hannia

    2001-04-01

    Stereochemistry is often a difficult topic for both science and non-science majors to learn. The topics covered in most undergraduate textbooks, although fundamental, seem very abstract to most students. This manuscript describes two simple exercises that can be used to introduce concepts associated with stereochemistry such as "sameness", superimposability, chirality, enantiomers, optical activity, polarimetry, and racemic mixtures. One exercise compares chirality in hands with the achiral nature of two textbooks. The other exercise involves a murder mystery, the solution of which hinges upon understanding the concept of optical activity, specifically in natural products such as toxins from poisonous mushrooms.

  3. Successful Innovative Methods in Introducing Astronomy Courses

    NASA Astrophysics Data System (ADS)

    Chattejee, T. K. C.

    2006-08-01

    Innovating new informative methods to induce interest in students has permitted us to introduce astronomy in several universities and institutes in Mexico. As a prelude, we gave a popular course in the history of astronomy. This was very easy as astronomy seems to be the most ancient of sciences and relating the achievements of the ancient philosophers/scientists was very enlightening. Then we put up an amateur show of the sky every week (subject to climatic conditions for observability). We showed how to take photographs and make telescopic observations. We enlightened the students of the special missions of NASA and took them to museums for space exploration. We gave a popular seminar on "Astrodynamics," highlighting its importance. We gave a series of introductory talks in radio and T.V. Finally we exposed them to electronic circulars, like "Universe Today" and "World Science." The last mentioned strategy had the most electrifying effect. We may not have been successful without it, as the students began to take the matter seriously only after reading numerous electronic circulars. In this respect, these circulars are not only informative about the latest news in astronomy, but highlight the role of astronomy in the modern world. Without it, students seem to relate astronomy to astrology; it is due to this misconception that they are not attracted to astronomy. Students were hardly convinced of the need for an astronomy course, as they did not know about the scope and development of the subject. This awakened the interests of students and they themselves proposed the initiation of an elementary course in astronomy to have a feel of the subject. Later on they proposed a course on "Rocket Dynamics." We will discuss our methods and their impact in detail.

  8. Introducing educational theory: vaginal examination.

    PubMed

    Killingley, Jo

    2015-09-01

    A vaginal examination (VE) is one of many core skills used in midwifery practice. Despite the controversy of whether it is necessary in all situations, in this article I take the standpoint that it is useful in providing a full clinical picture, especially at times when closer monitoring is recommended. Additionally, if the core skill is misinterpreted, the findings of the VE can distort the true clinical picture. To support the student, subjective assessment and individual learning pathways must be addressed to avoid unnecessary intervention and psychological impairment to the woman. This article explores some of the difficulties encountered with teaching and learning VE in clinical practice and offers concepts from educational theory to assist in clarifying the difficulties and offering new ways of thinking for both students and midwives.

    Invasive species can alter environments in such a way that normal behavioural decision-making rules of native species are no longer adaptive. The evolutionary trap concept provides a useful framework for predicting and managing the impact of harmful invasive species. We discuss how native species can respond to changes in their selective regime via evolution or learning. We also propose novel management strategies to promote the long-term co-existence of native and introduced species in cases where the eradication of the latter is either economically or biologically unrealistic.

  10. Introducing heifers to freestall housing.

    Little work to date has assessed how dairy cattle respond when first introduced to freestall housing. In this study we carried out 2 experiments. The aim of experiment 1 was to assess the behavioral responses of naïve heifers to pens fitted with freestalls. Holstein heifers (n=7 groups, each containing 3 heifers, 3 mo of age), with no previous experience with freestalls, were initially housed on a sawdust bedded pack and fed through a fixed feed barrier for at least 6 wk and then moved to a freestall pen fitted with a head-locking feed barrier. When kept on the bedded pack, the heifers' lying time averaged 14.2 h/d. On the day heifers were moved to the freestall pen, lying times declined by 2.9 h, but recovered on the following days. The time spent lying down on the barn floor (i.e., outside the lying area) increased by 2.5 h on the day heifers were introduced to freestalls and remained higher during subsequent days. Heifers spent 46 min/d less time feeding on the day they were switched to the head-locking barrier, but recovered on the following days. In experiment 2 we assessed the behavioral responses of naïve heifers introduced to pens fitted with freestalls with or without a neck rail. Holstein heifers (n=12 groups, each containing 2 heifers, 3 mo of age), with no previous experience with freestalls, were initially housed on a sawdust bedded pack and then moved to a freestall pen with or without neck rails. Heifers spent 4.2 h/d less time lying down in the 24 h following introduction into the freestall pen; the neck rail treatment had no effect on lying time but heifers spent more time standing with just their front 2 hooves in the stall when a neck rail was in the stall. In summary, lying and feeding behavior of naïve heifers is altered following introduction to new housing. PMID:21426979

  11. Intraband absorption in the 8-12 μm band from Si-doped vertically aligned InGaAs/GaAs quantum-dot superlattice

    Normal-incident infrared absorption in the 8-12-μm-atmospheric spectral window in the InGaAs/GaAs quantum-dot superlattice is observed. Using cross-sectional transmission electron microscopy, we find that the InGaAs quantum dots are perfectly vertically aligned in the growth direction (100). Under the normal incident radiation, a distinct absorption peaked at 9.9 μm is observed. This work indicates the potential of this quantum-dot superlattice structure for use as normal-incident infrared imaging focal arrays application without fabricating grating structures.

  12. Bare-Minimum Fluorous Mixture Synthesis of a Stereoisomer Library of 4,8,12-Trimethylnonadecanols and Predictions of NMR Spectra of Saturated Oligoisoprenoid Stereoisomers

    2013-01-01

    All four diastereomers of a typical saturated oligoisoprenoid, 4,8,12-trimethylnonadecanol, are made by an iterative three step cycle with the aid of traceless thionocarbonate fluorous tags to encode configurations. The tags have a minimum number of total fluorine atoms, starting at zero and increasing in increments of one. With suitable acquisition and data processing, each diastereomer exhibited characteristic chemical shifts of methyl resonances in its 1H and 13C NMR spectra. Together, these shifts provide a basis to predict the appearance of the methyl region of the spectrum of every stereoisomer of higher saturated oligoisoprenoids. PMID:23297872

    Williamson, Kathryn; Willoughby, S.

    2013-01-01

    Multiple-choice Concept Inventories (CIs) have become important tools in the Astronomy Education Research community for assessing student learning and the effects of instructional interventions. We introduce for the first time the Newtonian Gravity Concept Inventory (NGCI), a 26-item research validated instrument to quickly and effectively assess introductory college astronomy students’ understanding of gravity. The conceptual focus of the NGCI covers four conceptual domains: (1) Independence of gravity from other factors (such as air pressure, magnetism, and rotation), (2) Application of the force law (including mass and distance proportionality relationships), (3) Behavior at certain thresholds (such as low mass and high distance limits, as well as atmospheric boundaries), and (4) Directionality (for objects on Earth or orbiting, and including superposition. After three iterations of testing and refining, the NGCI has proven to be both a reliable and valid instrument. As evidence, we present a full statistical analysis of overall instrument reliability, item difficulty and item discriminatory power, supplemented with qualitative information from think-aloud student interviews and expert review

  15. Minerals Bill introduced in House

    NASA Astrophysics Data System (ADS)

    Richman, Barbara T.

    A bill that aims to strengthen a national minerals policy and to establish a three-member White-House-level council to coordinate the development of this policy was introduced in the House of Representatives on April 30 by James D. Santini (D-Nev.). Entitled the National Minerals Security Act (NMSA), the legislation, if passed, also would amend tax laws to assist the mining industry to make capital investments to locate and produce strategic minerals; it would provide the means for the Secretary of the Interior to make withdrawn public lands available for mineral development; and it would create a revolving fund for the sale and purchase of strategic minerals.Santini estimates that 4 billion tons of minerals are needed annually to sustain the nation's economy. Much of the minerals are supplied by other nations, however; Santini wants to see an end to the United States' dependence on foreign countries, especially those that seem relatively unstable politically. ‘The U.S. has placed its national security in the hands of a few foreign nations,’ Santini said in a recent press conference. ‘We are heavily dependent on the region of southern Africa for 76% of our cobalt, 93% of our platinum, 48% of our chromium, and a host of other strategic and critical minerals. Without these minerals, we cannot build jet aircraft, weapons, or other military hardware vitally important to our national security.’

  2. Introducing Astronomy Related Research into Non-Astronomy Courses

    NASA Astrophysics Data System (ADS)

    Walker, Douglas

    The concern over the insufficient number of students choosing to enter the science and engineering fields has been discussed and documented for years. While historically addressed at the national level, many states are now recognizing that the lack of a highly-skilled technical workforce within their states' borders has a significant effect on their economic health. Astronomy, as a science field, is no exception. Articles appear periodically in the most popular astronomy magazines asking the question, "Where are the young astronomers?" Astronomy courses at the community college level are normally restricted to introductory astronomy I and II level classes that introduce the student to the basics of the night sky and astronomy. The vast majority of these courses is geared toward the non-science major and is considered by many students to be easy and watered down courses in comparison to typical physics and related science courses. A majority of students who enroll in these classes are not considering majors in science or astronomy since they believe that science is "boring and won't produce any type of career for them." Is there any way to attract students? This paper discusses an approach being undertaken at the Estrella Mountain Community College to introduce students in selected mathematics courses to aspects of astronomy related research to demonstrate that science is anything but boring. Basic statistical techniques and understanding of geometry are applied to a large virgin data set containing the magnitudes and phase characteristics of sets of variable stars. The students' work consisted of developing and presenting a project that explored analyzing selected aspects of the variable star data set. The description of the data set, the approach the students took for research projects, and results from a survey conducted at semester's end to determine if student's interest and appreciation of astronomy was affected are presented. Using the data set provided, the

    Bryant, Wesley; Baker, Blane

    2016-09-01

    The concept of reactance in AC electrical circuits is often non-intuitive and difficult for students to grasp. In order to address this lack of conceptual understanding, classroom exercises compare the predicted resistance of a power tool, based on electrical specifications, to measured resistance. Once students discover that measured resistance is smaller than expected, they are asked to explain these observations using previously studied principles of magnetic induction. Exercises also introduce the notion of inductive reactance and impedance in AC circuits and, ultimately, determine self-inductance of the motor windings within the power tool.

  13. Water-vapor foreign-continuum absorption in the 8-12 and 3-5 μm atmospheric windows

    NASA Astrophysics Data System (ADS)

    Klimeshina, T. E.; Rodimova, O. B.

    2015-08-01

    The frequency and temperature dependence of the water vapor-nitrogen continuum in the 8-12 and 3-5 μm spectral regions obtained experimentally by CAVIAR and NIST is described with the use of the line contour constructed on the basis of asymptotic line shape theory. The parameters of the theory found from fitting the calculated values of the absorption coefficient to the pertinent experimental data enter into the expression for the classical potential describing the center-of-mass motion of interacting molecules and into the expression for the quantum potential of two interacting molecules. The frequency behavior of the line wing contours appears to depend on the band the lines of which make a major contribution to the absorption in a given spectral interval. The absorption coefficients in the wings of the band in question calculated with the line contours obtained for other bands are outside of experimental errors. The distinction in the line wing behavior may be explained by the difference in the quantum energies of molecules interacting in different vibrational states.

    The causes of night blindness in children are multifactorial and particular consideration has been given to childhood nutritional deficiency, which is the most common problem found in underdeveloped countries. Such deficiency can result in physiological and pathological processes that in turn influence biological sample composition. This study was designed to compare the levels of selenium (Se) and mercury (Hg) in scalp hair, blood, and urine of night blindness children age ranged (3-7) and (8-12) years of both genders, comparing them to sex- and age-matched controls. A microwave-assisted wet acid digestion procedure was developed as a sample pretreatment for the determination of Se and Hg in biological samples of night blindness children. The proposed method was validated by using conventional wet digestion and certified reference samples of hair, blood, and urine. The Se and Hg in biological samples were measured by electrothermal atomic absorption spectrometry and cold vapor atomic absorption spectrometry, prior to microwave acid digestion, respectively. The concentration of Se was decreased in scalp hair and blood samples of male and female night blindness children while Hg was higher in all biological samples as compared to referent subjects. The Se concentration was inversely associated with the risk of night blindness in both genders. These results add to an increasing body of evidence that Se is a protecting element for night blindness. These data present guidance to clinicians and other professional investigating deficiency of essential micronutrients in biological samples (scalp hair and blood) of night blindness children.

    2011-06-01

    In the 8-12 micron waveband Focal Plane Arrays (FPA) are available with a 17 micron pixel pitch in different arrays sizes (e.g. 512 x 480 pixels and 320 x 240 pixels) and with excellent electrical properties. Many applications become possible using this new type of IR-detector which will become the future standard in uncooled technology. Lenses with an f-number faster than f/1.5 minimize the diffraction impact on the spatial resolution and guarantee a high thermal resolution for uncooled cameras. Both effects will be quantified. The distinction between Traditional f-number (TF) and Radiometric f-number (RF) is discussed. Lenses with different focal lengths are required for applications in a variety of markets. They are classified by their Horizontal field of view (HFOV). Respecting the requirements for high volume markets, several two lens solutions will be discussed. A commonly accepted parameter of spatial resolution is the Modulation Transfer Function (MTF)-value at the Nyquist frequency of the detector (here 30cy/mm). This parameter of resolution will be presented versus field of view. Wide Angle and Super Wide Angle lenses are susceptible to low relative illumination in the corner of the detector. Measures to reduce this drop to an acceptable value are presented.

    2010-01-01

    Parathyroid hormone-like hormone (PTHLH) is an important chondrogenic regulator; however, the gene has not been directly linked to human disease. We studied a family with autosomal-dominant Brachydactyly Type E (BDE) and identified a t(8;12)(q13;p11.2) translocation with breakpoints (BPs) upstream of PTHLH on chromosome 12p11.2 and a disrupted KCNB2 on 8q13. We sequenced the BPs and identified a highly conserved Activator protein 1 (AP-1) motif on 12p11.2, together with a C-ets-1 motif translocated from 8q13. AP-1 and C-ets-1 bound in vitro and in vivo at the derivative chromosome 8 breakpoint [der(8) BP], but were differently enriched between the wild-type and BP allele. We differentiated fibroblasts from BDE patients into chondrogenic cells and found that PTHLH and its targets, ADAMTS-7 and ADAMTS-12 were downregulated along with impaired chondrogenic differentiation. We next used human and murine chondrocytes and observed that the AP-1 motif stimulated, whereas der(8) BP or C-ets-1 decreased, PTHLH promoter activity. These results are the first to identify a cis-directed PTHLH downregulation as primary cause of human chondrodysplasia. PMID:20015959

    2016-05-01

    A low power wavelet denoising chip for photoplethysmography (PPG) detection and portable heart rate monitoring is presented. To eliminate noise and improve detection accuracy, Harr wavelet (HWT) is chosen as the processing tool. An optimized finite impulse response structure is proposed to lower the computational complexity of proposed algorithm, which is benefit for reducing the power consumption of proposed chip. The modulus maxima pair location module is design to accurately locate the PPG peaks. A clock control unit is designed to further reduce the power consumption of the proposed chip. Fabricated with the 0.18 μm N-well CMOS 1P6M technology, the power consumption of proposed chip is only 8.12 μW in 1 V voltage supply. Validated with PPG signals in multiparameter intelligent monitoring in intensive care databases and signals acquired by the wrist photoelectric volume detection front end, the proposed chip can accurately detect PPG signals. The average sensitivity and positive prediction are 99.91% and 100%, respectively.

    2008-12-01

    During the summer of 2008, university faculty and instructors from southeast Alaska joined the University Alaska Fairbanks(UAF)Alaska Summer Research Academy(ASRA)to initiate a 12-day module on glacier change and biologic succession in Glacier Bay National Park. Nine students from Alaska, Colorado, Massachusetts, and Texas, made field observations and collected data while learning about tidewater glacier dynamics, plant succession, post-glacial uplift, and habitat use of terrestrial and marine vertebrates and invertebrates in this dynamic landscape that was covered by 6,000 km2 of ice just 250 years ago. ASRA students located their study sites using GPS and created maps in GIS and GOOGLE Earth. They deployed salinometers and temperature sensors to collect vertical profiles of seawater characteristics up-bay near active tidewater glacier termini and down-bay in completely deglaciated coves. ASRA student data was then compared with data collected during the same time period by Juneau undergraduates working on the SEAMONSTER project in Mendenhall Lake. ASRA students traversed actively forming, up-bay recessional moraines devoid of vegetation, and the fully reforested Little Ice Age terminal moraine near Park Headquarters in the lower bay region. Students surveyed marine organisms living between supratidal and subtidal zones near glaciers and far from glaciers, and compared up-bay and down-bay communities. Students made observations and logged sightings of bird populations and terrestrial mammals in a linear traverse from the bay's northwestern most fjord near Mt. Fairweather for 120 km to the bay's entrance, south of Park Headquarters at Bartlett Cove. One student constructed an ROV and was able to deploy a video camera and capture changing silt concentrations in the water column as well as marine life on the fjord bottom. Students also observed exhumed Neoglacial spruce forests and visited outcrops of Silurian reef faunas, now fossilized in Alexander terrane

  14. Introducing Interactive Teaching Styles into Astronomy Lectures

    NASA Astrophysics Data System (ADS)

    Deming, G. L.

    1997-12-01

    The majority of undergraduate students who take an astronomy class are non-science majors attempting to satisfy a science requirement. Often in these "scientific literacy" courses, facts are memorized for the exam and forgotten shortly afterwards. Scientific literacy courses should advance student skills toward processing information and applying higher order thinking rather than simple recall and memorization of facts. Thinking about material as it is presented, applying new knowledge to solve problems, and thinking critically about topics are objectives that many astronomy instructors hope their students are achieving. A course in astronomy is more likely to achieve such goals if students routinely participate in their learning. Interactive techniques can be quite effective even in large classes. Examples of activities are presented that involve using cooperative learning techniques, writing individual and group "minute papers," identifying and correcting misconceptions, including the whole class in a demonstration, and applying knowledge to new situations.

    A large-scale study ( Forder et al 2012 ) piloting personal health budgets for people with long-term conditions found that they improved patients' quality of life and psychological wellbeing. They were cost-effective and reduced the use of other healthcare services. From April next year, people receiving NHS continuing healthcare funding will have the right to ask for personal health budgets. Some clinical commissioning groups are also introducing them for mental health service users and patients with other long-term conditions. This article outlines the benefits and challenges of introducing personal health budgets, and suggests how nursing managers can begin to consider their role in implementing them. PMID:24063340

  3. Learning to Stand: The Acceptability and Feasibility of Introducing Standing Desks into College Classrooms.

    PubMed

    Benzo, Roberto M; Gremaud, Allene L; Jerome, Matthew; Carr, Lucas J

    2016-01-01

    Prolonged sedentary behavior is an independent risk factor for multiple negative health outcomes. Evidence supports introducing standing desks into K-12 classrooms and work settings to reduce sitting time, but no studies have been conducted in the college classroom environment. The present study explored the acceptability and feasibility of introducing standing desks in college classrooms. A total of 993 students and 149 instructors completed a single online needs assessment survey. This cross-sectional study was conducted during the fall semester of 2015 at a large Midwestern University. The large majority of students (95%) reported they would prefer the option to stand in class. Most students (82.7%) reported they currently sit during their entire class time. Most students (76.6%) and instructors (86.6%) reported being in favor of introducing standing desks into college classrooms. More than half of students and instructors predicted having access to standing desks in class would improve student's "physical health", "attention", and "restlessness". Collectively, these findings support the acceptability of introducing standing desks in college classrooms. Future research is needed to test the feasibility, cost-effectiveness and efficacy of introducing standing desks in college classrooms. Such studies would be useful for informing institutional policies regarding classroom designs. PMID:27537901

  8. Introducing thermodynamics through energy and entropy

    NASA Astrophysics Data System (ADS)

    de Abreu, Rodrigo; Guerra, Vasco

    2012-07-01

    We suggest a simple approach to introducing thermodynamics, beginning with the concept of internal energy of deformable bodies. From a series of thought experiments involving ideal gases, we show that the internal energy depends on the volume and on a second parameter, leading to the development of the concept of entropy. By introducing entropy before the notions of temperature and heat, the proposed approach avoids some of the major conceptual difficulties with the traditional presentation. The relationship between mechanics and thermodynamics naturally emerges, mechanics corresponding to isentropic thermodynamics. The questions of evolution to equilibrium and irreversibility are studied under the light of the action of the "dynamic force" and its dissipative character, evincing the benefits of keeping in mind the microscopic picture.

  9. [Effects of introducing Eucalyptus on indigenous biodiversity].

    PubMed

    Ping, Liang; Xie, Zong-Qiang

    2009-07-01

    Eucalyptus is well-known as an effective reforestation tree species, due to its fast growth and high adaptability to various environments. However, the introduction of Eucalyptus could have negative effects on the local environment, e. g., inducing soil degradation, decline of groundwater level, and decrease of biodiversity, and especially, there still have controversies on the effects of introduced Eucalyptus on the understory biodiversity of indigenous plant communities and related mechanisms. Based on a detailed analysis of the literatures at home and abroad, it was considered that the indigenous plant species in the majority of introduced Eucalyptus plantations were lesser than those in natural forests and indigenous species plantations but more than those in other exotic species plantations, mainly due to the unique eco-physiological characteristics of Eucalyptus and the irrational plantation design and harvesting techniques, among which, anthropogenic factors played leading roles. Be that as it may, the negative effects of introducing Eucalyptus on local plant biodiversity could be minimized via more rigorous scientific plantation design and management based on local plant community characteristics. To mitigate the negative effects of Eucalyptus introduction, the native trees and understory vegetation in plantations should be kept intact during reforestation with Eucalyptus to favor the normal development of plant community and regeneration. At the same time, human disturbance should be minimized to facilitate the natural regeneration of native species. PMID:19899483

  11. A multi-spectral optical system (1.55μm and 8 - 12μm) of GASIR ®1 design and coating aspects

    NASA Astrophysics Data System (ADS)

    Zadravec, Dusan; Franks, John W.; Rogers, Kenneth A.; Hendry, Alec F.; Drach, Patrick

    2009-05-01

    Small size and low weight are among the main drivers in modern military hand-held applications. Consequently, design-ers of such systems strive for combining multiple optical and electronic functions into the same piece of hardware. Present paper deals with the partial integration of an eye safe laser rangefinder into an optical channel for uncooled thermal imager using UMICORE's GASIR® optics. GASIR® is a chalcogenide glass with a transmission window from 0.8-15 µm, making it an effective material for use in near infrared, mid-wave infrared and far infrared applications. Due to the fact that uncooled sensors in the LWIR spectral band require optics with low f/numbers and that laser range-finders typically need a larger receiver aperture - in order to comply with the maximum range requirement - this ap-proach at first sight promises favorable synergies. However, it soon turns out that such a dual band approach makes life for the rangefinder part of the job difficult - by imposing special surface types required for achieving optical specifica-tions of the thermal channel, which may deteriorate the beam quality of the laser light as well as by introducing special coatings with potentially insufficient transmission at the specific laser wavelength. Several design versions have been developed and evaluated with the purpose of finding optimal balance between image quality of the thermal channel and the laser rangefinder performance. In this paper various optical and coating design aspects will be addressed together with the limitations of such a multi-spectral approach.

  13. Introducing personal digital assistants to enhance nursing education in undergraduate and graduate nursing programs.

    PubMed

    Cibulka, Nancy J; Crane-Wider, Lottchen

    2011-02-01

    This article describes how a school of nursing implemented an innovative program to introduce personal digital assistants to undergraduate and graduate nursing students. Undergraduate students studying pharmacology and nurse practitioner graduate students in an adult health course were asked to purchase a personal digital assistant privately or through the university bookstore. Faculty selected an appropriate software package. After students were oriented to the hardware and software package, innovative teaching strategies were implemented to help guide students to use their mobile devices to access clinically relevant information. Student feedback about this experience was positive. The most important elements for successful adoption of personal digital assistants are to provide training for both faculty and students, and to develop learning opportunities using the technology. Use of mobile technologies is an important competency that will improve the quality of nursing practice and therefore should be included in nursing curricula. PMID:21210606

  14. Need a Classroom Stimulus? Introduce Radio Astronomy

    NASA Astrophysics Data System (ADS)

    Derman, Samuel

    2010-04-01

    Silently, invisibly, ceaselessly, our planet Earth is showered by radio waves from every direction and from every region of space. This radio energy originates in our solar system, throughout the Milky Way galaxy, and far beyond, out to the remotest reaches of the universe. Detecting and unraveling the origins of these invisible signals is what radio astronomy is all about. This ever-present radiation provides astronomers with an alternate, non-optical window to the universe, revealing exotic and unfamiliar phenomena previously undetected by even the most powerful optical telescopes. For physics teachers, a classroom discussion of these radio discoveries, however brief, offers an opportunity for igniting interest (and possibly a career option) in even the most apathetic of students. This paper describes, first, the background of some of these events, and second (in the appendixes), a selection of numerical problems so that students can derive for themselves the truly mind-stretching features of these celestial objects.

  15. Introducing Seismic Tomography with Computational Modeling

    NASA Astrophysics Data System (ADS)

    Neves, R.; Neves, M. L.; Teodoro, V.

    2011-12-01

    Learning seismic tomography principles and techniques involves advanced physical and computational knowledge. In depth learning of such computational skills is a difficult cognitive process that requires a strong background in physics, mathematics and computer programming. The corresponding learning environments and pedagogic methodologies should then involve sets of computational modelling activities with computer software systems which allow students the possibility to improve their mathematical or programming knowledge and simultaneously focus on the learning of seismic wave propagation and inverse theory. To reduce the level of cognitive opacity associated with mathematical or programming knowledge, several computer modelling systems have already been developed (Neves & Teodoro, 2010). Among such systems, Modellus is particularly well suited to achieve this goal because it is a domain general environment for explorative and expressive modelling with the following main advantages: 1) an easy and intuitive creation of mathematical models using just standard mathematical notation; 2) the simultaneous exploration of images, tables, graphs and object animations; 3) the attribution of mathematical properties expressed in the models to animated objects; and finally 4) the computation and display of mathematical quantities obtained from the analysis of images and graphs. Here we describe virtual simulations and educational exercises which enable students an easy grasp of the fundamental of seismic tomography. The simulations make the lecture more interactive and allow students the possibility to overcome their lack of advanced mathematical or programming knowledge and focus on the learning of seismological concepts and processes taking advantage of basic scientific computation methods and tools.

  16. Introducing linear functions: an alternative statistical approach

    NASA Astrophysics Data System (ADS)

    Nolan, Caroline; Herbert, Sandra

    2015-12-01

    The introduction of linear functions is the turning point where many students decide if mathematics is useful or not. This means the role of parameters and variables in linear functions could be considered to be `threshold concepts'. There is recognition that linear functions can be taught in context through the exploration of linear modelling examples, but this has its limitations. Currently, statistical data is easily attainable, and graphics or computer algebra system (CAS) calculators are common in many classrooms. The use of this technology provides ease of access to different representations of linear functions as well as the ability to fit a least-squares line for real-life data. This means these calculators could support a possible alternative approach to the introduction of linear functions. This study compares the results of an end-of-topic test for two classes of Australian middle secondary students at a regional school to determine if such an alternative approach is feasible. In this study, test questions were grouped by concept and subjected to concept by concept analysis of the means of test results of the two classes. This analysis revealed that the students following the alternative approach demonstrated greater competence with non-standard questions.

    Technical development of human civilisation brings about a decrease of adaptation potential of an individual, which is directly linked to deficient motor activity. Only precise identification of factors leading to hypokinesia would make prophylactic and therapeutic actions possible. In this article, authors would like to introduce a new, original tool aiming at diagnosing limitations of motor activity in adults. They propose a synthetic diagnosis of hypokinesia in two domains: biological and psycho-social, which is based on the contemporary model of health. PMID:23487514

    2011-12-01

    The problem of Earth environmental destruction by human activities is becoming dangerous. Engineers responsible for the production of any goods should be well aware of the negative influence of their activities on the state of the planet. This is why the understanding of ecological problems is essential for people responsible for production and industrial design. The energy, which they consume, is increasing the greenhouse effect and the waste poisons the environment. So far, most courses on ecology are offered to specialists in environmental engineering. These courses are filled with many details. The Warsaw Academy of Computer Science, Management and Administration teaches students in the direction of management and production engineering. Upon completion, the students receive the degree of 'engineer'. Their future work will mainly concern management of different types of industrial enterprises and they will be responsible for organising it in such a way as to avoid a dangerous contribution to environmental pollution and climate change. This is why it was decided to introduce a new course entitled 'Principles of Ecology and Environmental Management'. This course is quite broad, concerning almost all technical, law and organisational aspects of the problem. The presentation is made in a spectacular way, aiming to convince students that their future activity must be environmentally friendly. It contains information about international activities in ecology, legal aspects concerning pollution, technical and information methods of monitoring and, finally, the description of 'green' solutions. Altogether, 27 hours of lectures and 15 hours of discussions and students' presentations complete the course. Details of this course are described in this paper.

  20. [Financial impact of introducing filmless CRT diagnosis].

    Kusakabe, Yukihiro

    2002-09-01

    There has been a great deal of discussion as to the cost and benefit of introducing filmless CRT diagnosis for radiological exams. Although the various advantages of the filmless system tend to be highlighted, very few studies have attempted to provide a quantitative estimate of the degree of impact. We analyzed the potential financial impact on the cost of film management (film development, maintenance, and transportation) if CRT diagnosis were to be introduced in Seirei Hamamatsu Hospital. In conducting this analysis, we assumed that CRT diagnosis initially would be limited to CT and MR. The analysis demonstrated that the actual yearly cost of managing films amounts to about 240 million yen. As individual items, the cost of film materials, labor, and depreciation of assets were the three largest cost sectors, with the cost of film accounting for more than 30% of the total. The expense attributable to CT and MR exams was roughly half of the total cost. Against this level of expense, the expected savings in the first year after shifting to the filmless system would be 100 million yen, or a 36% reduction in current expenses. This savings reflects various effects of system change, including lack of need for related materials, reduction in staff workload, elimination of unnecessary equipment, etc. Under the simulation we conducted, 70% of savings occurred in the area of variable costs and 30% in the area of fixed costs.

    Cook, David M.

    2006-12-01

    In the winter of 2003, we at Lawrence University moved Lagrangian mechanics and rigid body dynamics from a required sophomore course to an elective junior/senior course, freeing 40% of the time for computational approaches to ordinary differential equations (trajectory problems, the large amplitude pendulum, non-linear dynamics); evaluation of integrals (finding centers of mass and moment of inertia tensors, calculating gravitational potentials for various sources); and finding eigenvalues and eigenvectors of matrices (diagonalizing the moment of inertia tensor, finding principal axes), and to generating graphical displays of computed results. Further, students begin to use LaTeX to prepare some of their submitted problem solutions. Placed in the middle of the sophomore year, this course provides the background that permits faculty members as appropriate to assign computer-based exercises in subsequent courses. Further, students are encouraged to use our Computational Physics Laboratory on their own initiative whenever that use seems appropriate. (Curricular development supported in part by the W. M.

    Klaassen, Kees; Westra, Axel; Emmett, Katrina; Eijkelhof, Harrie; Lijnse, Piet

    2008-07-01

    This article concerns an outline of an introductory mechanics course. It is based on the argument that various uses of the concept of force (e.g. from Kepler, Newton and everyday life) share an explanatory strategy based on core causal knowledge. The strategy consists of (a) the idea that a force causes a deviation from how an object would move of its own accord (i.e. its force-free motion), and (b) an incentive to search, where the motion deviates from the assumed force-free motion, for recurring configurations with which such deviations can be correlated (interaction theory). Various assumptions can be made concerning both the force-free motion and the interaction theory, thus giving rise to a variety of specific explanations. Kepler's semi-implicit intuition about the force-free motion is rest, Newton's explicit assumption is uniform rectilinear motion, while in everyday explanations a diversity of pragmatic suggestions can be recognized. The idea is that the explanatory strategy, once made explicit by drawing on students' intuitive causal knowledge, can be made to function for students as an advance organizer, in the sense of a general scheme that they recognize but do not yet know how to detail for scientific purposes. A previous version of this article was presented at the 2006 GIREP Conference.

    2013-04-01

    Newly established by the American Astronomical Society (AAS), the Astronomy Ambassadors program is designed to support early-career AAS members with training in resources and techniques for effective outreach to students and/or the public. A pilot Astronomy Ambassadors workshop will be held at the January 2013 AAS meeting. Workshop participants will learn to communicate effectively with public and school audiences; find outreach opportunities and establish ongoing partnerships with local schools, science centers, museums, parks, and/or community centers; reach audiences with personal stories, hands-on activities, and jargon-free language; identify strategies and techniques to improve their presentation skills; gain access to a menu of outreach resources that work in a variety of settings; and become part of an active community of astronomers who do outreach. Applications are welcome from advanced undergraduates (those doing research and committed to continuing in astronomy), graduate students, and postdocs and new faculty in their first two years after receipt of the PhD. We especially encourage applications from members of groups that are presently underrepresented in science.

  6. Introducing fear of crime to risk research.

    PubMed

    Jackson, Jonathan

    2006-02-01

    This article introduces the fear of crime to risk research, noting a number of areas for future interdisciplinary study. First, the article analyzes both the career of the concept of fear of crime and the politics of fear. Second, it considers research and theory on the psychology of risk, particularly the interplay between emotion and cognition, and what might be called the risk as image perspective. Third, the article speculates how people learn about risk and suggests how to customize a social amplification of risk framework to fear of crime. Finally, the article advances the argument that fear of crime may be an individual response to community social order and a generalized attitude toward the moral trajectory of society. Each of these areas of discussion has implications for future theoretical developments within risk research; each highlights how risk research can contribute to the social scientific understanding of an important issue of the day.

    Lack of competence teachers to educate basic science astronomy and space science in Indonesia implies that knowledge of astronomy and space science will be transmitted to the young generation improperly. Priority in curriculum of basic science include only small amount of general astronomy and public perception that astronomy is less importance than basic science both are disadvantage for developing astronomical community in Indonesia a country with more than 230 million people. Muslim community in Indonesia has a tradition to use a lunar calendar and a tradition to determine the first day the important month Ramadhan Syawal and Dzulhijjah. Recent disputeof determining the first day of the three important month partly due to the lack of knowledge the first visibility of lunar crescent. The challenge of introducing astronomy on wider community with less background on astronomical education will be discussed in this paper

    2003-06-25

    The increasing presence of computers and other forms of information and communications technology (ICT) in schools has raised concerns in the United States (US) and elsewhere. Children are using computers more than any other age group in the US. It is not known whether early intensive use of ICT predisposes children to future injury. Ergonomics is not included in state curriculum standards or requirements but can be supported by some of the existing standards. Some who believe that children are better off being educated early about ergonomics are taking action to bring ergonomics into elementary and secondary schools. This paper describes the process used to introduce ergonomics into two elementary schools in two different states by initiators with two different roles.

  10. Towards Introducing Space Science in Uganda

    NASA Astrophysics Data System (ADS)

    Anguma, S.; Ayikoru, J.

    This paper discusses the strategies and importance of introducing space science in Uganda. It proposes that Mbarara University, as a new university focusing on science and technology, would be ideally situated to spearhead the introduction of space science in Uganda. It is our expectation that this will have a spin-off effect to other higher institutions of learning and that consequently space science will become fully incorporated into the national teaching curriculum for all schools in Uganda. Based on the fact that the Government has a deliberate policy of popularizing science and technology to accelerate national economic development, the introduction of space science in the school system is to be enhanced by these efforts. We have charted the way forward for space science in Uganda and outlined the conceptual framework illustrating the spin-off effect into the education system.

    PURPOSE The principal risks of needle biopsy are hemorrhage and implantation of tumor cells in the needle tract. This study compared hemorrhage after liver and kidney biopsy with and without radiofrequency (RF) ablation of the needle tract. MATERIALS AND METHODS Biopsies of liver and kidney were performed in swine through introducer needles modified to allow RF ablation with the distal 2 cm of the needle. After each biopsy, randomization determined whether the site was to undergo RF ablation during withdrawal of the introducer needle. Temperature was measured with a thermistor stylet near the needle tip, with a target temperature of 70°C–100°C with RF ablation. Blood loss was measured as grams of blood absorbed in gauze at the puncture site for 2 minutes after needle withdrawal. Selected specimens were cut for gross examination. RESULTS RF ablation reduced bleeding compared with absence of RF ablation in liver and kidney (P < .01), with mean blood loss reduced 63% and 97%, respectively. Mean amounts of blood loss (±SD) in the liver in the RF and no-RF groups were 2.03 g ± 4.03 (CI, 0.53–3.54 g) and 5.50 g ± 5.58 (CI, 3.33–7.66 g), respectively. Mean amounts of blood loss in the kidney in the RF and no-RF groups were 0.26 g ± 0.32 (CI, −0.01 to 0.53 g) and 8.79 g ± 7.72 (CI, 2.34–15.24 g), respectively. With RF ablation, thermal coagulation of the tissue surrounding the needle tract was observed. CONCLUSION RF ablation of needle biopsy tracts reduced hemorrhage after biopsy in the liver and kidney and may reduce complications of hemorrhage as well as implantation of tumor cells in the tract.

  13. Introducing Python tools for magnetotellurics: MTpy

    NASA Astrophysics Data System (ADS)

    Krieger, L.; Peacock, J.; Inverarity, K.; Thiel, S.; Robertson, K.

    2013-12-01

    Within the framework of geophysical exploration techniques, the magnetotelluric method (MT) is relatively immature: It is still not as widely spread as other geophysical methods like seismology, and its processing schemes and data formats are not thoroughly standardized. As a result, the file handling and processing software within the academic community is mainly based on a loose collection of codes, which are sometimes highly adapted to the respective local specifications. Although tools for the estimation of the frequency dependent MT transfer function, as well as inversion and modelling codes, are available, the standards and software for handling MT data are generally not unified throughout the community. To overcome problems that arise from missing standards, and to simplify the general handling of MT data, we have developed the software package "MTpy", which allows the handling, processing, and imaging of magnetotelluric data sets. It is written in Python and the code is open-source. The setup of this package follows the modular approach of successful software packages like GMT or Obspy. It contains sub-packages and modules for various tasks within the standard MT data processing and handling scheme. Besides pure Python classes and functions, MTpy provides wrappers and convenience scripts to call external software, e.g. modelling and inversion codes. Even though still under development, MTpy already contains ca. 250 functions that work on raw and preprocessed data. However, as our aim is not to produce a static collection of software, we rather introduce MTpy as a flexible framework, which will be dynamically extended in the future. It then has the potential to help standardise processing procedures and at same time be a versatile supplement for existing algorithms. We introduce the concept and structure of MTpy, and we illustrate the workflow of MT data processing utilising MTpy on an example data set collected over a geothermal exploration site in South

  14. Introducing systems biology for nursing science.

    Founds, Sandra A

    2009-07-01

    Systems biology expands on general systems theory as the "omics'' era rapidly progresses. Although systems biology has been institutionalized as an interdisciplinary framework in the biosciences, it is not yet apparent in nursing. This article introduces systems biology for nursing science by presenting an overview of the theory. This framework for the study of organisms from molecular to environmental levels includes iterations of computational modeling, experimentation, and theory building. Synthesis of complex biological processes as whole systems rather than isolated parts is emphasized. Pros and cons of systems biology are discussed, and relevance of systems biology to nursing is described. Nursing research involving molecular, physiological, or biobehavioral questions may be guided by and contribute to the developing science of systems biology. Nurse scientists can proactively incorporate systems biology into their investigations as a framework for advancing the interdisciplinary science of human health care. Systems biology has the potential to advance the research and practice goals of the National Institute for Nursing Research in the National Institutes of Health Roadmap initiative. PMID:19221104

    Tropical forests are essential components of the earth system and play a critical role for land surface feedbacks to climate change. These forests are currently experiencing large-scale structural changes, including the increase of liana abundance and biomass. This liana proliferation might have large impacts on the carbon cycle of tropical forests. However no single global vegetation model currently accounts for lianas. The TREECLIMBERS project (ERC starting grant) aims to introduce for the first time lianas into a vegetation model. The project attempts to reach this challenging goal by performing a global meta-analysis on liana data and by collecting new data in South American forests. Those new and existing datasets form the basis of a new liana plant functional type (PFT) that will be included in the Ecosystem Demography model (ED2). This presentation will show an overview of the current progress of the TREECLIMBERS project. Liana inventory data collected in French Guiana along a forest disturbance gradient show the relation between liana abundance and disturbance. Xylem water isotope analysis indicates that trees and lianas can rely on different soil water resources. New modelling concepts for liana PFTs will be presented and in-situ leaf gas exchange and sap flow data are used to parameterize water and carbon fluxes for this new PFT. Finally ongoing terrestrial LiDAR observations of liana infested forest will be highlighted.

    The goal of the Virtual Astronomy Multimedia Project (VAMP) is to promote and vastly multiply the use of astronomy multimedia resources—from images and illustrations to animations, movies, and podcasts—and enable innovative future exploitation of a wide variety of outreach media by systematically linking resource archives worldwide. High-quality astronomical images, accompanied by rich caption and background information, abound on the web and yet prove notoriously difficult to locate efficiently using existing search tools. The Virtual Astronomy Multimedia Project offers a solution via the Astronomy Visualization Metadata (AVM) standard. Due to roll out in time for IYA2009, VAMP manages the design, implementation, and dissemination of the AVM standard for the education and public outreach astronomical imagery that observatories publish. VAMP will support implementations in World Wide Telescope, Google Sky, Portal to the Universe, and 365 Days of Astronomy, as well as Uniview and DigitalSky software designed specifically for planetariums. The VAMP workshop will introduce the AVM standard and describe its features, highlighting sample image tagging processes using diverse tools—the critical first step in getting media into VAMP. Participants with laptops will have an opportunity to experiment first hand, and workshop organizers will update a web page with system requirements and software options in advance of the conference (see http://virtualastronomy.org/ASP2008/ for links to resources). The workshop will also engage participants in a discussion and review of the innovative AVM image hierarchy taxonomy, which will soon be extended to other types of media.

  19. Introducing Knowledge into Differential Expression Analysis

    PubMed Central

    Biecek, Przemysław; Tiuryn, Jerzy; Vingron, Martin

    2010-01-01

    Abstract Gene expression measurements allow determining sets of up- or down-regulated, or unchanged genes in a particular experimental condition. Additional biological knowledge can suggest examples of genes from one of these sets. For instance, known target genes of a transcriptional activator are expected, but are not certain to go down after this activator is knocked out. Available differential expression analysis tools do not take such imprecise examples into account. Here we put forward a novel partially supervised mixture modeling methodology for differential expression analysis. Our approach, guided by imprecise examples, clusters expression data into differentially expressed and unchanged genes. The partially supervised methodology is implemented by two methods: a newly introduced belief-based mixture modeling, and soft-label mixture modeling, a method proved efficient in other applications. We investigate on synthetic data the input example settings favorable for each method. In our tests, both belief-based and soft-label methods prove their advantage over semi-supervised mixture modeling in correcting for erroneous examples. We also compare them to alternative differential expression analysis approaches, showing that incorporation of knowledge yields better performance. We present a broad range of knowledge sources and data to which our partially supervised methodology can be applied. First, we determine targets of Ste12 based on yeast knockout data, guided by a Ste12 DNA-binding experiment. Second, we distinguish miR-1 from miR-124 targets in human by clustering expression data under transfection experiments of both microRNAs, using their computationally predicted targets as examples. Finally, we utilize literature knowledge to improve clustering of time-course expression profiles. PMID:20726790

    As biological sequence data are generated at an ever increasing rate, the role of bioinformatics in biological research also grows. Students must be trained to complete and interpret bioinformatic searches to enable them to effectively utilize the trove of sequence data available. A key bioinformatic tool for sequence comparison and genome database searching is BLAST (Basic Local Alignment Search Tool). BLAST identifies sequences in a database that are similar to the entered query sequence, and ranks them based on the length and quality of the alignment. Our goal was to introduce sophomore and junior level undergraduate students to the basic functions and uses of BLAST with a small group activity lasting a single class period. The activity provides students an opportunity to perform a BLAST search, interpret the data output, and use the data to make inferences about bacterial cell envelope structure. The activity consists of two parts. Part 1 is a handout to be completed prior to class, complete with video tutorial, that reviews cell envelope structure, introduces key terms, and allows students to familiarize themselves with the mechanics of a BLAST search. Part 2 consists of a hands-on, web-based small group activity to be completed during the class period. Evaluation of the activity through student performance assessments suggests that students who complete the activity can better interpret the BLAST output parameters % query coverage and % max identity. While the topic of the activity is bacterial cell wall structure, it could be adapted to address other biological concepts. PMID:24358388

    No improvement yet: German school students, although initially curious about geo- and other natural sciences, often tend to drop these subjects as they grow older. Their argument: "the stuff is too hard". Other reasons could be: - instruction is too theoretical and therefore boring - students do not see the benefit, because natural science disciplines in school are isolated and the connection to real life is missing - for some students, the intellectual level of instruction is too low, because teachers have to orient their presentation to the average student. A good way to improve the attractiveness is to bring interdisciplinary, application, and/or global perspective aspects into the classroom. Geosciences have the enormous advantage of being interdisciplinary per se: All other natural sciences not only those taught in school find their implementation in this field. The Research Center Ocean Margins (RCOM), a geoscientific institute at Bremen University, focuses on paleoclimate as one of its research highlights. This subject is ideal for demonstrating interdisciplinary and global aspects that students can also work out for themselves. Another bonus is its inherent allure and fascination. Activities within the "Science and School" program at RCOM include training courses for teachers (Sommeruniversitaet), and lab courses for kids from elementary to high-school level (UNISchullabor), as well as lectures and courses for the younger school children (ages 8-12 years, KinderUniversitaet). All activities focus on (re-)motivating school kids for natural sciences and maintaining their interest by special initiatives like "Years of Science" or "Summer of Science". This year, for the first time, we offered a project for highly motivated and/or gifted high school students, the ones that often think of school as boring because they do not feel challenged. In a one-week initiation course we introduced them to science and research work. The focus lay on "Climate of the past

    1. Co-introductions of non-native parasites with non-native hosts can be a major driver of disease emergence in native species, but the conditions that promote the establishment and spread of nonnative parasites remain poorly understood. Here, we characterise the infection of a native host species by a non-native parasite relative to the distribution and density of the original non-native host species and a suite of organismal and environmental factors that have been associated with parasitism, but not commonly considered within a single system. 2. We examined the native Hawaiian goby Awaous stamineus across 23 catchments on five islands for infection bymore » the non-native nematode parasite Camallanus cotti. We used model selection to test whether parasite infection was associated with the genetic diversity, size and population density of native hosts, the distribution and density of non-native hosts, land use and water quality. 3. We found that the distribution of non-native C. cotti parasites has become decoupled from the non-native hosts that were primary vectors of introduction to the Hawaiian Islands. Although no single intrinsic or extrinsic factor was identified that best explains parasitism of A. stamineus by C. cotti, native host size, population density and water quality were consistently identified as influencing parasite intensity and prevalence. 4. The introduction of non-native species can indirectly influence native species through infection of co-introduced parasites. Here, we show that the effects of enemy addition can extend beyond the range of non-native hosts through the independent spread of non-native parasites. This suggests that control of non-native hosts is not sufficient to halt the spread of introduced parasites. Furthermore, designing importation regulations to prevent host parasite co-introductions can promote native species conservation, even in remote areas that may not seem susceptible to human influence.« less

    To develop students' sensitivity toword medication hazards, we have introduced a behavioral approach, "Kiken-Yochi Training" (KYT) for hazard prediction training to pharmacy education. KYT was originally implemented in the field of occupational health and safety in Japan. Only recently it has been introduced in the medical arena. The process consists of four steps; identification of hazards, assessing risks, planning countermeasure, and making action plan. One facilitator organizes the KYT class (20 students divided into four or five small groups). Watching a photo or illustration of everyday occurrences, each group follows the above four steps to discuss predictable hazards. Concepts are intensively presented in short time with brainstorming. KYT has been used with five classes thus far. Students learned KYT theory and exhibited desired attitudes and behaviors. Students presented many ideas, then formulated their own action plan within about one hour. More than 95% of KYT-naïve students assessed themselves as capable of applying the methodology in various situations. They also assessed themselves as being more aware of potential hazards and new points of view through the KYT process. Pharmacists must work for safer and more effective pharmacotherapy, predicting hazards as side effect or human error and solving the problems on each patient. KYT is a very useful and effective tool for pro-active safety training for the skill and attitude development. Repeating problem-based learning like KYT at intervals through undergraduate education should improve patient safety. PMID:19881209

    The Mars Rover Celebration and Mars Rover Curriculum (MRC) for grades 3-8 are centered around an open-ended, student-led collaborative project to design a mission to Mars. This curriculum incorporates up-to-date SMD education resources and science and mission data relating to NASA's explorations of Mars. The MRC focuses on the adventure of learning and discovery, asking participating teams to propose their own scientific mission to Mars, design a rover to carry it out, and present a mock-up at an open house. The curriculum is structured to be inquiry-based throughout. The "students choose the mission" structure is highly engaging. The latter half of the curriculum presents the Engineering Design Process and walks the students through the steps of designing and engineering a spacecraft/rover to meet the mission objectives chosen by the students. Students are introduced to engineering using the design-project approach. The six-week project period culminates in a public celebration at which students present their missions to members of the community including undergraduate and graduate students in science, engineering, and education fields; university faculty in these fields; and professionals from associated industries.

  10. Pitfalls to avoid when introducing a cultural competency training initiative.

    Chun, Maria B J

    2010-06-01

    OBJECTIVES In an effort to provide preventive advice, this paper aims to acknowledge what has not worked with regard to cultural competency initiatives. A successful cultural competency training initiative should have lasting impact on its participants in terms of long-term, ideally permanent changes to attitudes, knowledge and skills resulting in the provision of optimum care, regardless of a patient's cultural background. Legal mandates mean there is an assumed need for cultural competency curricula and training programmes for medical students and postgraduate medical trainees. However, policy and practice have bypassed 'proof' that such programmes are effective and result in better patient care. Often only positive results are reported, which may minimise the difficulties involved in programme implementation. METHODS Utilising the example of a cultural competency initiative introduced into a postgraduate general surgery training programme, this paper discusses mistakes that were made during the implementation phase, particularly with regard to underestimating potential resistance by the trainees. Also presented are the lessons learned and efforts that were made to mitigate the problems that arose. None of what is discussed in this paper is new. However, the literature often does not discuss in detail the difficulties that can be or have been faced and how these obstacles can be adequately mitigated. CONCLUSIONS The glow of cultural competency training initiatives is fading in the light of higher expectations for an evidence base prior to acknowledgement that their introduction has had a positive impact. For these initiatives to advance, there needs to be a clear understanding of terms utilised, buy-in and a long-term commitment at both individual and organisational levels, and use of standardised and validated tools to measure outcomes. An understanding of potential pitfalls can help to advance cultural competency training to the next level, namely, a solid

    It has been shown that supplementation with omega-3 improves cognitive performance, especially in infants and toddlers, but it is unknown whether these results are effective in older malnourished children. The aims of this study, therefore, were to investigate the omega-3 supplementation effects in 8- to 12-year-old children and to know which neuropsychological functions improve after three months of intervention in a sample of Mexican children with mild to moderate malnutrition. This study was a randomized, double-blind, treatment and placebo study of 59 children aged 8-12 years who were individually allocated to 2 groups. The duration of the intervention lasted 3 months. Neuropsychological performance was measured at baseline and at 3 months. Results show that more than 50% of children in the treatment group had greater improvement in 11 of the 18 neuropsychological variables studied. Processing speed, visual-motor coordination, perceptual integration, attention and executive function showed improvement in more than 70% of the omega-3 supplemented children. This trial was registered at clinicaltrials.gov as NCT01199120. PMID:24508294

    The development of computational tools and methods has changed the way science is done. This change, however, is far from being accomplished on high school and college curricula, where computers are mainly used for showing text, images and animations. Most curricula do not consider the use of computational scientific tools, particularly tools where students can manipulate and build mathematical models, as an integral part of the learning experiences all students must have. In this paper, we discuss how Modellus, a freely available software tool (created in Java and available for all operating systems) can be used to support curricula where students from the age of 12 to college years can be introduced to scientific computation. We will also show how such a wide range of learners and their teachers can use Modellus to implement simple numerical methods and interactive animations based on those methods to explore advanced mathematical and physical reasoning.

    2015-04-01

    The Italian coastline is about 7,500 km long; approximately 53% of the coastlines are low or deltaic coastlines, while 3,240 km were mainly composed of sand or gravel beaches. Most of the Italian coastal environment suffers from intense and growing urbanization, tourism and industry pressure, which could partly explain that 42% of Italian beaches experience erosion. Terracina is situated Lazio (Central Italy), a region strongly impacted by coastal erosion, and for this reason we organized a teaching activity, carried out with fourth year high school classes, in order to help students to understand sand beach dynamics, acquisition of geology issues and land conservation and preservation skills. We decided to focus our activity on the mineralogical composition of beach sand in order to relate beach formations with the geological evolution of the territory. Sand beach minerals were used as tracers in order to support students to understand dynamics that influence beach formations. In addition to mineral characteristic recognition, this activity allows us to introduce the beach balance concept and the phenomena that regulate sediment balance, in order to allow students to consider beaches as a resource which needs to be preserved. Sand mineralogical composition data is treated in a worksheet to elaborate simple statistical analysis in order to recognize the mineral composition of Terracina beach sand's rock sources. This exercise allows students to find relationships between regional geology and beach sand's composition. Finally, statistical evidence could be compared with geological maps of the area in order to find the probable provenance of sand's rock source and rocks recognition thanks to related morphologies. Our main purpose was to help students to understand that beaches are dynamic systems subject to anthropogenic pressure and for this reason they needed to be preserved. Proposed teaching activities involve topics related to students' living territory and to

    The practice of statistics is the focus of the world in which professional statisticians live. To understand meaningfully what this practice is about, students need to engage in it themselves. Acknowledging the limitations of a genuine classroom setting, this study attempted to expose four classes of year 5 students ( n = 91) to an authentic experience of the practice of statistics. Setting an overall context of people's habits that are considered environmentally friendly, the students sampled their class and set criteria for being environmentally friendly based on questions from the Australian Bureau of Statistics CensusAtSchool site. They then analysed the data and made decisions, acknowledging their degree of certainty, about three populations based on their criteria: their class, year 5 students in their school and year 5 students in Australia. The next step was to collect a random sample the size of their class from an Australian Bureau of Statistics `population', analyse it and again make a decision about Australian year 5 students. At the end, they suggested what further research they might do. The analysis of students' responses gives insight into primary students' capacity to appreciate and understand decision-making, and to participate in the practice of statistics, a topic that has received very little attention in the literature. Based on the total possible score of 23 from student workbook entries, 80 % of students achieved at least a score of 11.

    2008-03-01

    In Japan, problem-based learning (PBL) is a relatively new method of educating medical students that is reforming the face of medical education throughout the world, including Asia. It shifts from teacher-centered learning strategies (for example, lectures in large auditoriums) to student-centered, self-directed learning methods (for example, active discussions and problem-solving by students in small groups under the guidance of faculty tutors). Upon a recommendation by the Japan Model Core Curriculum, Saga Medical School introduced a PBL curriculum 5 years ago. A full PBL curriculum was adopted from the McMaster model through Hawaii. A description of how PBL was implemented into the 3rd and 4th year (Phase III curriculum) is given. The overall result has been good. Students who experienced PBL had increased scores on the National Medical License Exam, and Saga increased its ranking from 56th to 19th of the 80 medical schools in Japan. A key step was introduction of the educational scaffolding in PBL Step 0. Students were allowed to see page one of the PBL case, containing the chief complaint, on the weekend before meeting in small groups. Despite a perceived overall benefit to student learning, symptoms of superficial discussions by students have been observed recently. How this may be caused by poor case design is discussed. Other problems, including "silent tutors" and increased faculty workload, are discussed. It is concluded that after 5 years, Saga's implementation of a PBL curriculum has been successful. However, many additional issues, including motivation of students and preparation for PBL in the first 2 years, must still be resolved in the future. This is the first description of the positive and negative outcomes associated with the reform of medical education and the introduction of PBL to a traditional medical school curriculum in Japan.

  18. Introduced species and management of a Nothofagus/Austrocedrus forest.

    PubMed

    Simberloff, Daniel; Relva, Maria Andrea; Nunez, Martin

    2003-02-01

    Isla Victoria (Nahuel Huapi National Park, Argentina), a large island dominated by native Nothofagus and Austrocedrus forest, has old plantations of many introduced tree species, some of which are famed invaders of native ecosystems elsewhere. There are also large populations of introduced deer and shrubs that may interact in a complex way with the introduced trees, as well as a recently arrived population of wild boar. Long-standing concern that the introduced trees will invade and transform native forest may be unwarranted, as there is little evidence of progressive invasion, even close to the plantations, despite over 50 years of opportunity. Introduced and native shrubs allow scattered introduced trees to achieve substantial size in abandoned pastures, but in almost all areas neither the trees nor the shrubs appear to be spreading beyond these sites. These shrub communities may be stable rather than successional, but the technology for restoring them to native forest is uncertain and probably currently impractical. Any attempt to remove the exotic tree seedlings and saplings from native forest would probably create the very conditions that would favor colonization by exotic plants rather than native trees, while simply clear-cutting the plantations would be unlikely to lead to regeneration of Nothofagus or Austrocedrus. The key to maintaining native forest is preventing catastrophic fire, as several introduced trees and shrubs would be favored over native dominant trees in recolonization. Deer undoubtedly interact with both native and introduced trees and shrubs, but their net effect on native forest is not yet clear, and specific management of deer beyond the current hunting by staff is unwarranted, at least if preventing tree invasion is the goal. The steep terrain and shallow soil make the recently arrived boar a grave threat to the native forest. Eradication is probably feasible and should be attempted quickly. PMID:12520381

    The zonal workshops organized by the space education outreach unit of the African Regional Centre for Space Science and Technology Education utilized recent catastrophic events in Nigeria to attract pre-collegiate youths to space science and technology (SST). About 200 school children, aged between 10 and 18 years participated in the program which was coordinated at 2 different geopolitical zones in Nigeria in 2014. The 2-day event was packed with a lot of fun-filled, hands-on educational activities demonstrating the use of outer space to address prevailing socio-economic problems in the nation. The students were introduced to the Nigerian Earth Observation Satellites, and learned why these satellites cannot be used to track the school girls kidnapped by the terrorist group in the northern part of the country. They were also introduced to other types of satellites and participated in activities on the applications of TRMM satellite data to monitor flood events in Nigeria. The Global Positioning System (GPS) technology was introduced as a navigational tool to curb criminal activities in the country and participants used the hand-held GPS unit for geocaching. The program culminated in the launching of space clubs in all the participating schools and a teacher from each school received resource materials on DVD to nurture the space club. To assess the impact of the workshop on the knowledge level of the participants in space science, quiz competitions were administered and the average score of the students was above 70%. The enthusiasm displayed by the students, coupled with the brilliant performance in the evaluation tests, indicated that this method of informal education, that linked science to the alleviation of national disasters is viable, not only for stimulating the interest of Nigerian pre-collegiate youths in SST, but also to inspire the young learners and develop their interest in the Sciences, Technology, Engineering and Mathematics (STEM).

  5. Introduced birds incompletely replace seed dispersal by a native frugivore.

    PubMed

    2015-01-01

    The widespread loss of native species and the introduction of non-native species has important consequences for island ecosystems. Non-native species may or may not functionally replace the role of native species in ecological processes such as seed dispersal. Although the majority of Hawaii's native plants require bird-mediated seed dispersal, only one native frugivore, Omao (Myadestes obscurus), persists in sufficient numbers to fill this functional role. Omao are restricted to less than half their original range, but two introduced frugivores are abundant throughout Hawaii. Given large-scale extinctions on islands, it is important to understand whether introduced birds serve as functional replacements or whether the absence of native frugivores alters plant communities. To assess seed dispersal by native and introduced birds, seed rain, vegetation characteristics, bird diet, density and habitat use were measured at three sites with Omao and three sites without Omao on Hawaii Island. The diet of native and introduced birds overlapped substantially, but Omao dispersed a variety of native species (n = 6) relatively evenly. In contrast, introduced birds dispersed an invasive species and fewer native species (n = 4), and >90 % of seeds dispersed by introduced birds were from two ubiquitous small-seeded species. Seed rain was significantly greater and more species rich at sites with Omao. These findings suggest that patterns of seed dispersal are altered following the local extinction of a native island frugivore. To more directly evaluate the relative roles of native and introduced frugivores in ecological processes, future studies could include reintroducing Omao to a suitable habitat within its historic range, or novel introductions to nearby islands where closely related species are now extinct. In an era of widespread extinction and invasion of island ecosystems, understanding the consequences of novel animal assemblages for processes like seed dispersal will be

    A pilot project introduced 12 minutes of text and video materials and a reflective online interaction about elder abuse into the online component of a hybrid course in nursing assistant training leading to certification. Didactic presentations on issues of ethics and standards had been given in two different units of the face-to-face component of the course using both the course textbook and an online module keyed to state certification standards. However, student responses suggested that their online writing to each other about the new materials brought issues of elder abuse to the forefront in ways that they could finally internalize.

    In an era when many students carry iPods, iPhones, and iPads, physics teachers are realizing that in order to continue to inspire and convey the amazing things made possible by a few fundamental principles, they must expand laboratory coverage of electricity and circuits beyond the conventional staples of constructing series and parallel arrangements of light bulbs and confirming Kirchhoff's laws. Indeed, physics teachers are already incorporating smartphones into their laboratory activities in an effort to convey concepts in a more contemporary and relatable manner. As part of Cornell's Learning Initiative in Medicine and Bioengineering (CLIMB), we set out to design and implement an engaging curriculum to introduce high school physics students to filters and amplifiers.

    2010-06-01

    The chloroiron(III) complex of 2,8,12,18-tetrabutyl-3,7,13,17-tetramethyl-5,10-diazaporphyrin, [(Cl)FeMBDAP], was prepared and studied by X-ray crystallography and by solution (1)H NMR and UV-vis measurements. In the crystal structure of hemisolvate [(Cl)FeMBDAP] x 0.5CHCl(3), two nonequivalent [(Cl)FeMBDAP] units containing Fe1 and Fe2 are arranged in pi-dimers with considerable overlap on their concave sides. Axial chloride bonded to Fe2 is solvated by hydrogen bonding with CHCl(3). Parameters of the coordination pyramid have typical values for the spin-mixed (S = 3/2 / 5/2) Fe(III) complexes in the case of Fe1 and are characteristic for the pure intermediate-spin state for Fe2 (displacement from the (N(Pyr))(4) planes - 0.385 and 0.290 A and the average N(Pyr)-Fe bond lengths -1.992 and 1.954 A for Fe1 and Fe2, respectively). Effective magnetic moments in CHCl(3) and CH(2)Cl(2) capable of specific solvation of chloride by hydrogen bonding (4.5-4.6 micro(B) at 298 K) are indicative about mixed intermediate/high-spin state S = 3/2 / 5/2, with the S = 3/2 contribution increasing upon lowering of the temperature (4.02 micro(B) in CD(2)Cl(2) at 193 K). In nonsolvating CCl(4), C(6)D(6), and THF-d(8), the mu(eff) values are consistent with the predominantly high-spin state at ambient temperature (5.5-5.75 micro(B) at 298 K) and almost pure S = 5/2 state at low temperature (ca. 5.9 micro(B) in THF-d(8) below 270 K). Downfield isotropic shifts from 35 to 50 ppm are observed for alpha-alkyl protons and upfield shifts from -5 to -15 ppm for meso-CH protons, which is characteristic for the presence of the intermediate-spin state. The splitting of signals of the diastereotopic alpha-CH(2) protons is increased with growth of the S = 3/2 state contribution from 1.5 to 4 ppm in nonsolvating to 11 ppm in specifically solvating solvents at 298 K and further to 31 ppm at 193 K (in CD(2)Cl(2)). In the presence of DMSO addition and in methanol solution, the single CH(2) signal is

    2015-01-01

    The impacts of introduced northern pike (Esox lucius) on salmonid populations have attracted much attention because salmonids are popular subsistence, sport and commercial fish. Concern over the predatory effects of introduced pike on salmonids is especially high in Southcentral Alaska, where pike were illegally introduced to the Susitna River basin in the 1950s. We used pike abundance, growth, and diet estimates and bioenergetics models to characterise the realised and potential consumptive impacts that introduced pike (age 2 and older) have on salmonids in Alexander Creek, a tributary to the Susitna River. We found that juvenile salmonids were the dominant prey item in pike diets and that pike could consume up to 1.10 metric tons (realised consumption) and 1.66 metric tons (potential consumption) of juvenile salmonids in a summer. Age 3–4 pike had the highest per capita consumption of juvenile salmonids, and age 2 and age 3–4 pike had the highest overall consumption of juvenile salmonid biomass. Using historical data on Chinook salmon and pike potential consumption of juvenile salmonids, we found that pike consumption of juvenile salmonids may lead to collapsed salmon stocks in Alexander Creek. Taken together, our results indicate that pike consume a substantial biomass of juvenile salmonids in Alexander Creek and that coexistence of pike and salmon is unlikely without management actions to reduce or eliminate introduced pike.

    Why is there a section on introduced amphibians and reptiles in this volume, and why should veterinarians care about this issue? Globally, invasive species are a major threat to the stability of native ecosystems,1,2 and amphibians and reptiles are attracting increased attention as potential invaders. Some introduced amphibians and reptiles have had a major impact (e.g., Brown Tree Snakes [Boiga irregularis] wiping out the native birds of Guam3 or Cane Toads [Rhinella marina] poisoning native Australian predators).4 For the vast majority of species, however, the ecological, economic, and sociopolitical effects of introduced amphibians and reptiles are generally poorly quantified, largely because of a lack of focused research effort rather than because such effects are nonexistent. This trend is alarming given that rates of introduction have increased exponentially in recent decades.

    Abstract As the home becomes an increasingly important site for health care, an increasing number of technology applications or devices are being introduced to support health at home. However, introducing new technology into a household raises a number of issues that must be considered prior to, during, and after the technology is implemented. This paper reviews the experiences of the UW-Madison Advanced Technologies for Health@Home Project, summarizing our assessment of household requirements that should be analyzed prior to introducing new technology. The overall goal of the Health@Home project is to improve the functionality and content of information technology innovations for the home. Using Venkatesh and Mazumdar's framework this article will summarize the relevant social, behavioral, technological, and physical dimensions of households that must be carefully assessed and understood to help ensure that the technology fits the needs of home residents.

    2013-01-01

    Background With the introduction of integrated problem-based learning (PBL) program in the medical curriculum, there is a need to create laboratory classes that suit students’ learning needs and the changes introduced to the curriculum. This paper outlines the development and implementation of four integrated laboratory classes (ILCs) at King Saud University College of Medicine. It also examines whether core concepts addressed in these classes were learned and retained and how the students perceived the ILCs. Methods ILCs are based on enhancing enquiry-based learning, and encouraging students to work on tasks in small groups (apply and integrate knowledge from biochemistry, pathology and microbiology) and conduct a laboratory procedure (practical part). In two of these ILCs, a pretest comprising 15 multiple-choice questions were administrated at the start of the class and an identical posttest was administrated at the end of these classes. Performance of the students in the Objective Structured Practical Examination (OSPE) at the end of the blocks was also evaluated. Students’ perceptions were evaluated using a questionnaire completed at the end of each class. Results A total of 247, 252, 238, and 244 students participated in practical classes covering cerebrospinal fluid infection, small intestine, liver function tests and adrenal gland function, respectively. Students got higher scores in posttests compared to pre-test scores in two classes (12.68 ± 2.03 vs 6.58 ± 3.39 and 13.02 ± 2.03 vs 7.43 ± 2.68, respectively). Paired t-test showed that the difference was significant (P < 0.001) in both tests. The mean scores of students in stations dealing with ILCs at the end of the block examinations were not significantly different from the mean scores for other stations not related to ILCs. The questionnaire indicated that most students expressed positive attitude towards working on tasks and applying knowledge learnt. Students also felt that
