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

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.

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.

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.

, 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.

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.

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

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

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.

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

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.

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.

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.

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

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.

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.

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

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.

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.

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.

In our new global economy, biomedical product development teams need to be even more innovative in an environment constrained by fewer resources with less time from concept to market. Teams are often comprised of individuals spread around the world. To simulate this setting, we revised an existing course to incorporate teams of on-campus and distance students, with each team including both engineers and other specialties. Through interactive lectures and projects, we presented a systematic approach to innovation that should be useful to engineers and non-engineers alike. Students found the course challenging and exciting, displaying an improved ability to work in distributed teams and in developing innovative design solutions. PMID:17487063

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.

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
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

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

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.

Partners in Science is a cooperative program between Boehringer Ingelheim Pharmaceuticals, Inc. and area high schools in the community surrounding our Connecticut campus. It is a two-phase program that introduces high school students and teachers to the world of drug discovery and leading-edge pharmaceutical research. Phase 1 involves a series of lectures, tours, and demonstrations given by scientists within our research and development division (R&D). Phase 2 involves the selection of a small group of participants to intern for the summer in a research laboratory, working side by side with a scientist within R&D. In this manuscript, the specific aims, goals, and development of the Partners in Science program are described, as well as the syllabus/agenda, the logistics surrounding the operation of the program, and our shared personal experiences with students and teachers who have participated. Some of the pitfalls/problems associated with the program will be presented, and finally, the future direction of the program including areas of improvement and expansion are described.

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.

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.

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

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

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

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.

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.

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

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.

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.
Today, the pressure is on to enhance student success in higher education. Demands for accountability and mounting concerns about access are prompting educators to re-think traditional approaches to retention management and to look for new strategies.

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

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.

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

We surveyed first year students at the start and at the end of their first semester of university biology (n = 285) as to their approaches to study ("surface", "deep") and their conceptions of biology ("fragmented", "cohesive"). Hierarchical cluster analysis was used to group students who responded similarly to the survey; this resolved four…

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…

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.

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.

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

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.

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.
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.

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.

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.

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

Provides an exercise for introducing research methods to undergraduates. The students view a graph revealing that left-handed people are underrepresented in older age groups. Small group discussions attempt to explain this phenomenon. A follow-up class discussion focuses on the different approaches and methods available for interpreting the data.…

We describe a computer tutorial that introduces the concept of the steady state in enzyme kinetics. The tutorial allows students to produce graphs of the concentrations of free enzyme, enzyme-substrate complex, and product versus time in order to learn about the approach to steady state. By using a range of substrate concentrations and rate…

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
