  1. Memory for Lectures: How Lecture Format Impacts the Learning Experience

    PubMed Central

    Varao-Sousa, Trish L.; Kingstone, Alan

    2015-01-01

    The present study investigated what impact the presentation style of a classroom lecture has on memory, mind wandering, and the subjective factors of interest and motivation. We examined if having a professor lecturing live versus on video alters the learning experience of the students in the classroom. During the lectures, students were asked to report mind wandering and later complete a memory test. The lecture format was manipulated such that all the students received two lectures, one live and one a pre-recorded video. Results indicate that lecture format affected memory performance but not mind wandering, with enhanced memory in the live lectures. Additionally, students reported greater interest and motivation in the live lectures. Given that a single change to the classroom environment, professor presence, impacted memory performance, as well as motivation and interest, the present results have several key implications for technology-based integrations into higher education classrooms.

    Richard Floyd Darsie, Jr. (1915-2014) is the 2015 American Mosquito Control Association Memorial Lecture Honoree. He was one of the greatest mosquito taxonomists of the 20th century and died peacefully on April 10, 2014, in Grove City, PA, at the age of 99 after a professional career that spanned eight decades. Dick's broad areas of interest and training made him a versatile scientist, teacher, and researcher. His intense interest in adult and immature mosquito morphology and taxonomy, as well as mosquito distribution and bionomics, started early in his career at two early academic postings: Franklin and Marshall College (1949-54) and the University of Delaware (1954-62). Dick would take his mosquito interests with him to postings and research projects around the world: Nepal, the Philippines, Atlanta, El Salvador, Guatemala, Fort Collins, South Carolina, Argentina, and Florida. His travels and studies would make him an international expert on mosquito taxonomy. Dick's legacy lives on in the hundreds of students from across the globe who learned mosquito identification skills from this world-renowned mosquito taxonomist. All will proudly profess that, "I learned mosquito identification from Dr. Darsie." And that is all that is needed to prove one's credentials in the field, learning the art from the best there is.

    2007-06-01

    The Jamieson Memorial Lecture, delivered annually to the Neurosurgical Society of Australasia, commemorates the life and work of a leading Australasian neurosurgeon, Dr Kenneth Grant Jamieson (1925-1976), of Melbourne and Brisbane. He was the first specialist neurosurgeon to be appointed to the Brisbane General Hospital, the Brisbane Children's Hospital and the newly established Princess Alexandra Hospital in Queensland, jointly in 1956. He went on to serve as President of the Neurosurgical Society of Australasia (1971-1973) and as a Councillor of the Royal Australasian College of Surgeons from 1971 until his death. His pioneering research to study the sociophysical interplay of factors leading not only to head and spinal injury but to those causing all life-threatening trauma gave weight (from 1961) to advocacy for the introduction of breathalyser surveillance and to the compulsory wearing of seat belts in cars. In international perspective, Kenneth Jamieson was a pioneering 'accidentologist'. He was one of the first clinicians to address seriously the extraordinary burden of mortality from road trauma. He was a role model for those clinicians who came to see their professional and ethical duties extending to preventive and public health domains, both within and beyond the aegis of their chosen specialties. He saw a need for integration between the many bodies teaching resuscitation and life-support skills; at the 1975 Annual Scientific Meeting of the Royal Australasian College of Surgeons, he moved the motion to establish the Australian Resuscitation Council. The vigour and outreach of the Australian Resuscitation Council today remain one of his memorials. In the clinical sphere, his research centred on the early drainage of extradural haematomata and from 1962 on the operative treatment of aneurysms of the vertebral and basilar arteries. He was a dominant and leading advocate for clinical teaching in neurosurgery, particularly for more formal and sophisticated

  9. Memory modulation in the classroom: selective enhancement of college examination performance by arousal induced after lecture.

    Nielson, Kristy A; Arentsen, Timothy J

    2012-07-01

    Laboratory studies examining moderate physiological or emotional arousal induced after learning indicate that it enhances memory consolidation. Yet, no studies have yet examined this effect in an applied context. As such, arousal was induced after a college lecture and its selective effects were examined on later exam performance. Participants were divided into two groups who either watched a neutral video clip (n=66) or an arousing video clip (n=70) after lecture in a psychology course. The final examination occurred two weeks after the experimental manipulation. Only performance on the group of final exam items that covered material from the manipulated lecture were significantly different between groups. Other metrics, such as the midterm examination and the total final examination score, did not differ between groups. The results indicate that post-lecture arousal selectively increased the later retrieval of lecture material, despite the availability of the material for study before and after the manipulation. The results reinforce the role of post-learning arousal on memory consolidation processes, expanding the literature to include a real-world learning context.

    Since the beginning of the Space Age the public was fascinated by the great challenges that needed to be overcome, but also inspired by the potential benefits that might arise from the utilization of space systems. This lecture examines the major technological breakthroughs that were necessary for many of the key space programs to succeed, and postulates the immediate and future benefits to humanity that became evident as a result of these advances. A dozen programs ranging from Sputnik and Apollo to the Global Navigation Satellite System are reviewed in view of the technical challenges in elements such as propulsion, power, structures, computing, guidance and control, spectrum management and payloads. Challenges in the cost of space launch, large structures, debris mitigation, humans in space and commercial promise are discussed and opportunities for improvements in the future are postulated.

  11. Dupuytren's disease or Cooper's contracture?: Kenneth Fitzpatrick Russell Memorial Lecture.

    PubMed

    Thurston, Alan

    2003-07-01

    In his position as curator of the Cowlishaw collection of historical medical books in the Library of the College, Kenneth Russell prepared the definitive catalogue of the collection. This catalogue is comprehensive and for almost all entries there is an annotation that demonstrates his meticulous attention to detail and the love of the book collection that he managed to secure for the College. It is from this catalogue that I have chosen two books in particular that bring together two great surgeons of the turn of the 19th century. Although he was a pupil of the great John Hunter, the young Astley Cooper possessed good manners and a gift of oratory of which the Scot, his teacher, was devoid. After his apprenticeship with Henry Cline senior, Cooper came to share the podium with Cline at Guy's and St Thomas' hospitals and the two dominated surgical teaching in London for some 22 years, until Cline's retirement in 1811. It was the latter who was first to recognize the true nature of the condition now known as Dupuytren's disease. Later, in 1822, Cooper wrote a detailed description of the contracture of the palmar aponeurosis and recommended fasciotomy as being curative. His book A Treatise on Dislocations and Fractures of the Joints, which contains this description of Dupuytren's contracture, is held in the Cowlishaw Collection. On the other side of the English Channel, M. le Baron Dupuytren repeatedly misquoted Cooper and stated that Cooper believed that the disease was incurable. In his famous lecture given to the staff of the Hôtel Dieu in Paris on 5th December 1931, he admitted to having seen 30 or 40 cases over 20 years of practice. It seems likely that he was not aware of the true cause of the condition before 1831 when he treated his first case. This lecture, along with others, are recorded in his Leçons Orales de Clinique Chirurgicale, a copy of which is also to be found in the Cowlishaw Collection.

    The first manned trip beyond Earth orbit was the historic Christmas Eve flight of Apollo 8. One of the critical objectives was to verify that astronauts could navigate in space using a sextant to measure star elevations above the Earth and Moon horizons with a recursive algorithm implemented in an onboard computer to process the measurements. The Apollo Guidance Computer was primitive by any modern comparison having but 72 kilobytes of ROM and 4 kilobytes of RAM with no mass memory or even the ability to up-link large quantities of data or programs. The computer had no built-in redundancy, no spare parts and no backup. The author gives a personal account of these events—how the hardware and software evolved and what really happened on that first manned trip to the Moon.

    The Medical Physics community lost one of its early pioneers in radiation oncology physics, Jacques Ovadia, who passed away in April of 2014 at the age of 90. Jacques received his Ph.D. in Nuclear Physics from the University of Illinois at Urbana in 1951. Subsequently, under the guidance of John Laughlin, he was introduced to the field of Medical Physics. When John moved to Memorial Sloan Kettering, Jacques followed him. There he gained clinical experience and expertise in the then cutting-edge field of high energy electron beam therapy. In 1956, Jacques joined Dr. Erich Uhlmann at Michael Reese Hospital in Chicago where one of the country’s first high energy medical linear accelerators had just been installed. During his 35 year tenure, Dr. Ovadia built a strong Medical Physics department that merged in 1984 with that of the University of Chicago. Jacques pioneered the use of high energy electron beams to treat deep seated tumors, multiple-field chest wall irradiation with variable electron energies, and even anticipated the current interest in high energy electron beam grid-therapy. At an early stage, he introduced a simulator, computerized treatment planning and in-house developed record and verify software. He retired in 1990 as Professor emeritus in Radiation and Cellular Biology at the University of Chicago. Dr. Ovadia was an early and strong supporter of AAPM. He was present at the Chicago ROMPS meeting where the decision was made to form an independent professional society for medical physics. He served as AAPM president in 1976. Jacques Ovadia is survived by his wife of 58 years, Florence, their daughter Corinne Graefe and son Marc Ovadia, MD, as well as four grandchildren and one great-grandchild. Jacques’ dynamic and ever enthusiastic personality inspired all who collaborated with him. He will be greatly missed.

    At 90 years of age, the APTA may be facing some of the greatest national and global challenges of its history. Membership has grown from 238 in 1921 to over 70,000 in 2011, but the expansion of the APTA may be restrictive to individual participation. A leadership gap appears imminent in practice and education. Fostering every member to understand the APTA and its great work is essential to ensuring a profession that lives its core values and meets societal needs. The Linda Crane Memorial Lecture in 2011 celebrated a vision of the APTA's 100th birthday with every member serving as a "professional centenarian" who stewards the organization to continued greatness.

    We lost a legendary medical physicist, Dr. Bengt Erik Bjarngard, to angiosarcoma an aggressive type of cancer. He devoted his life to providing improved methods of radiation treatment for this devastating disease over the last 36 years. Bengt was born in a rural village of Bjarnum in southern Sweden, located near forest and is known for its furniture making. He migrated to USA at the age of 35 and was recruited by Dr. Samuel Hellman to lead a group of physicists that became the “mecca of medical physics” known as the Joint Center of Radiation Therapy (JCRT) at Harvard Medical School in Boston. Bengt mentored some of the best physicists in the country, and many of our modern treatments go back to the early days of research at the JCRT. These accomplishments, dating from 1969–1989, include: dose optimization using computer control; soft wedges; stereotactic radiosurgery (SRS); total-body irradiation (TBI); CT-planning; and radiation dosimetry. Bengt worked at Brown University in Rhode Island and at the University of Pennsylvania in Philadelphia, where he provided major contributions in radiation dosimetry, specifically with the head scatter model. He advocated superior calculation algorithm through the Helax treatment planning system that was on par from most commercial systems. Bengt served as AAPM president in 1979 and was a recipient of the Coolidge Award in 1998. He had a lifelong love of nature, retiring in 2000 from the University of Pennsylvania to take care of his 200 acres of homestead forest in Maine. His legacy continues through his contributions to radiation dosimetry. This session, on small field dosimetry, is a small tribute to his memory. Further details can be found in his obituary in Med Phy, 41(4), 040801, 2014.

  17. Preston M. Hickey memorial lecture. Ionic and nonionic iodinated contrast media: evolution and strategies for use.

    1990-08-01

    The search for better radiopaque iodinated contrast material for intravascular use is continuing, but the recent development of new lower osmolality contrast media (LOCM), both ionic and nonionic, has dramatically affected the practice of radiology. The major issue retarding the introduction of LOCM into clinical practice in this country has been the increased cost of the media. Numerous preliminary assumptions and probabilities about the tolerance, efficacy, and overall safety of LOCM have been documented in scientific studies. The lower osmolality, reduced chemotoxicity, and high hydrophilicity of new compounds, particularly the nonionic variety compared with conventional high osmolality ionic agents (HOCM), offer a significant margin of safety to patients with known risk factors. Mounting data suggest that low or no risk patients are benefited as well, perhaps to an even greater degree. Costly trade-offs to the universal use of LOCM exist, therefore careful consideration of the advantages and disadvantages of LOCM for intravascular administration is required. This article, presented as the Preston M. Hickey Memorial Lecture to the Michigan Radiological Society in March of 1990, explores the historical development of iodinated intravascular contrast media, especially LOCM, and cites existing data that form the basis for various strategies for their use, that is, selective, universal, or nonvascular use. Better, safer, and less expensive contrast media are a realistic expectation in this new decade of technological promise. Reducing adverse side effects from the use of any new drug or technology must be our continued, collective goal.

    This inaugural memorial lecture provides an opportunity to celebrate the life of Elijah B. Saunders, MD, FACC and pays tribute to his pioneering spirit in the quest to advance health equity in the prevention and control of hypertension and cardiovascular diseases. It also enables an assessment of the state of the global burden of hypertension and related disparities. Despite the remarkable biomedical research progress made over the last half-century, hypertension remains the leading risk factor for global disease burden and the major preventable contributor to cardiovascular and all-cause mortality. Additionally, disparities in hypertension-related morbidity and mortality remain pervasive worldwide. National hypertension control rates showing progress often mask important suboptimal treatment and control in population groups defined by sex, race, ethnicity, geography, and social and environmental determinants. Within these groups, many hypertension-related disparities remain largely unchanged while other gaps have widened. In essence, current research has been relatively ineffective in guiding large-scale, sustained elimination of hypertension-related disparities. An important explanation for these observations may be the significant advances made in observational epidemiological research, especially in improved surveillance and data collection that document the extent of disparities in marked contrast to the relative paucity of interventional disparities research. The paucity of these interventional research studies remains a continuing challenge. The time has come for renewed efforts in building strategic partnerships that leverage transdisciplinary, multi-sectoral expertise to provide global leadership in interventional implementation research for hypertension control and elimination of related disparities. Developing an appropriately skilled implementation research workforce will be crucial. The National Heart, Lung, and Blood Institute and its biomedical

    The Great Russian physicist Academician A.M. Prokhorov passed away on the 8th of January 2002 in Moscow. He was born in Australia (Atorton Town) on the 11th of July 1916. Together with Academician N.G. Basov and Prof. C.H. Townes in 1964, he received the Nobel Prize in physics for discovery the fundamental operational principles of the LASER (Light Amplification by Stimulated Emission and Radiation). Among the great variety of scientific and technological areas to which Academician A.M. Prokhorov had devoted his extraordinary talent and his encyclopedical knowledge in physics, is the ultrafast photoelectronics and in particular image-converter high-speed photography. As early as at the beginning of the sixties, he clearly realized the importance and valuability of ultrafast image tubes application for gaining direct visual information in laser research. It was Academician A.M. Prokhorov who had initiated the image tube photography development specially oriented for laser investigations, providing steadily improvement of its time resolution starting from subnanosecond level in the sixties of the 20th Century down to subfemtosecond level at the beginning of the 21st Century. The new area of high-speed research, known as Femto-Attosecond Photoelectronics, is now established as the outstanding result of his imaginative efforts. In this memorial lecture some important achievements in the ultrafast photoelectronics attained under Academician A.M. Prokhorov supervision will be pointed out. Memorized are some perspective targets in high-speed image-converter photography to which Academician A.M. Prokhorov has been concerned during the last period of his brilliant and creative life.

    Dale, H

    1935-01-01

    A brief account is given of the scientific career of Walter Ernest Dixon, and of the importance of his work and his influence for the development of Pharmacology in England. It is suggested that the Memorial Lecture may appropriately deal with some matter of new interest, from one of the fields of research in which Dixon himself was active. Special mention is made of his work with Brodie on the physiology and pharmacology of the bronchioles and the pulmonary blood-vessels, as probably showing the beginning of Dixon's interest in the actions of the alkaloids and organic bases which reproduce the effects of autonomic nerves.An account is given of Dixon's early interest in the suggestion, first made by Elliott, that autonomic nerves transmit their effects by releasing, at their endings, specific substances, which reproduce their actions; and of his attempt to obtain experimental support for this conception. After the War it was established by the experiments of O. Loewi; and it is now generally recognized that parasympathetic effects are so transmitted by release of acetylcholine, sympathetic effects by that of a substance related to adrenaline.Very recent evidence indicates that acetylcholine, by virtue of its other ("nicotine-like") action, also acts as transmitter of activity at synapses in autonomic ganglia, and from motor nerve to voluntary muscle.The terms "cholinergic" and "adrenergic" have been introduced to describe nerve-fibres which transmit their actions by the release at their endings of acetylcholine, and of a substance related to adrenaline, respectively. It is shown that Langley and Anderson's evidence, long available, as to the kinds of peripheral efferent fibres which can replace one another in regeneration, can be summarized by the statement, that cholinergic can replace cholinergic fibres, and that adrenergic can replace adrenergic fibres; but that fibres of different chemical function cannot replace one another.

    There are many complex phenomena that are so familiar to us that we forget to ask whether or not they are understood. In this lecture, I will discuss several familiar cases of effects that are so ubiquitous that we hardly realize that they defy our normal intuition about why they happen. The examples of poorly understood classical physics that I will choose can all be viewed at a breakfast table. I will mention the long tendrils left behind by honey spooned from one dish to another, the anomalous flow behavior of granular material, and the annoying rings deposited by spilled coffee on a table after the liquid evaporates. These are all nonlinear hydrodynamic phenomena which not only are of technological importance but can also lead the inquisitive into new realms of physics.

    There are interesting challenges in leprosy right now. The last fifteen years have seen the world-wide implementation of multidrug therapy with tangible benefits for patients and doctors. Paradoxically this success has revealed how much we still need to understand about leprosy nerve damage. For patients it is imperative that nerve damage is detected at an early stage when damage is still reversible. They need effective education to prevent the development of disability and to minimise the social and economic effects of nerve damage. For doctors and paramedical workers nerve damage needs effective treatment. We need to use current treatments effectively and also develop new treatments. This lecture looks critically at the pathology, detection and treatment of nerve damage, reviewing our present knowledge and looking to future developments.

A recording of the lecture is included as supporting information and can also be viewed online here: https://www.youtube.com/watch?v=xrP81AQ8l-8. Pharmacological models used to describe drug agonism and antagonism have evolved over the past 20 years from a parsimonious model describing single active and inactive receptor states to models of multiconformational receptor systems modified by ligand conformational selection. These latter models describe the observed, presently underexploited, pharmacological mechanism of ligand-directed biased signalling. Biased signals can be quantified with transduction coefficients (ΔΔLog(τ/KA) values), a scale grounded in the Black/Leff operational model; this enables the optimization of biased profiles through medicinal chemistry. The past decades have also brought the availability of new technologies to measure multiple functional effects mediated by seven transmembrane receptors. These have confirmed that drugs can have many efficacies, which may be collaterally linked, that is there is no linear sequence of activities required. In addition, new functional screening assays have introduced increasing numbers of allosteric ligands into drug discovery. These molecules are permissive (they do not necessarily preclude endogenous signalling in vivo); therefore, they may allow better fine tuning of pathological physiology. The permissive quality of allosteric ligands can also change the quality of endogenous signalling efficacy (‘induced bias’) as well as the quantity of signal; in this regard, indices related to ΔΔLog(τ/KA) values (namely ΔLog(αβ) values) can be used to quantify these effects for optimization in the drug discovery process. All of these added scales of drug activity will, hopefully, allow better targeting of candidate molecules towards therapies. PMID:26075971

    Neurosurgeons in the last half-century have had considerable influence on modern-day athletics. In this article, the authors address the contributions made by neurosurgeons as clinician-scientists, particularly as these relate to the understanding and reduction of the incidence and severity of injury to the nervous system during athletic competition. American football has been a proving ground for the ability of the craniospinal axis to withstand and, in unfortunate cases, succumb to tremendous impact forces; in this way, it has served as a model for translational research and was the arena in which Dr. Richard Schneider made his greatest contributions to sports neurosurgery. Therefore, in his memory and in the spirit of the Schneider lectureship, the authors outline the notable contribution to modern-day athletics made by neurosurgeons as it applies to American football. Neurosurgeons have had considerable influence on reducing injury severity, and this cause has been championed by a few notable individuals whose efforts are discussed herein.

    João Magueijo's article "Cargo-cult training" about the failings of compulsory educational training for lecturers (December 2009 pp16-17) is an illustration of why some university lecturers do need to be educated about education. His argument that we should use lectures because students like them ignores the large body of educational research stating that this is the least effective form of education. It might, as the well-known aphorism states, be a successful means of transferring the notes of the lecturer to the notes of the students without going through the minds of either, but the evidence shows that only 10% of students learn material in this way. Rather, all the educational literature points to the fact that interactive, discursive methods are much more likely to produce learning with understanding.

    Historically, invited lecturers have often challenged us to define excel lence in physical therapy practice, or in our academic programs. While some have addressed different char acteristics of excellence, our profession has not really come together to address 2 very important questions: what does "quality" mean in physical therapist education? And how do we measure it? Using 3 elements of Friendship, Leadership, and Mentoring, and Defining Excellence and juxtaposing these with Linda Crane and her life, a vision of excellence in physical therapy educational programs was explored in this invited lecture.

    The Lecture covers the author's personal experience in brachytherapy in radiation oncology, beginning with low-dose rate (LDR) treatments using 226Ra "hot" sources, in the 1960s and early 1970s, through manual afterloading for treating gynaecological cancers with the same sources in the 1970s and 1980s, to high-dose rate (HDR) remote afterloading on a microSelectron HDR machine, from 1989 on. This progression in brachytherapy is discussed, and specific applications to various tumour sites are presented, including long-term results of a personal series of 106 patients with cancer of the uterine cervix, treated with radiotherapy incorporating HDR brachytherapy.

Dr Poth was a surgical educator from the University of Texas Medical Branch, Galveston who was President of the Southwestern in 1963. The paper presents the history of the founding of the American Board of Surgery, with particular emphasis on the certifying examination-Part 2. Vignettes of occurrences associated with the "Oral" examination are given. The examination has changed substantially from a 2-day event involving an actual surgical procedure to the 90-minute quiz given today. The oral examinations remain an important part in the process of certification of surgeons of the highest quality.

  10. Klopsteg Memorial Lecture (August, 1998): Physics at the breakfast table{emdash}or waking up to physics

    There are many complex phenomena that are so familiar to us that we forget to ask whether or not they are understood. In this lecture, I will discuss several familiar cases of effects that are so ubiquitous that we hardly realize that they defy our normal intuition about why they happen. The examples of poorly understood classical physics that I will choose can all be viewed at a breakfast table. I will mention the long tendrils left behind by honey spooned from one dish to another, the anomalous flow behavior of granular material, and the annoying rings deposited by spilled coffee on a table after the liquid evaporates. These are all nonlinear hydrodynamic phenomena which not only are of technological importance but can also lead the inquisitive into new realms of physics. {copyright} {ital 1999 American Association of Physics Teachers.}

  2. Elder abuse and neglect--"old phenomenon": new directions for research, legislation, and service developments. (2008 Rosalie S. Wolf Memorial Elder Abuse Prevention Award--International Category Lecture).

    PubMed

    Lowenstein, Ariela

    2009-01-01

    This article poses the question: Is elder abuse and neglect a social problem, showing that it is. Elder abuse, though, is still the most hidden form of mistreatment and a key to governmental responses to an ageing population. It is an important facet as a family violence problem, an intergenerational concern, as well as a health, justice and human rights issue. Because the phenomenon of elder abuse and neglect is so complex and multi-dimensional, it has to be addressed by multi-professional and inter-disciplinary approaches. Raising awareness is a fundamental prevention strategy and an important step in causing changes in attitudes and behaviors. This has been accomplished by INPEA and the article was developed from the lecture given by the author on receiving the International Rosalie Wolf Award from INPEA. The discussion focuses on elder abuse as a product of global ageing, stemming from population ageing, which is consistent with an increased prevalence of abuse of all vulnerable groups, older people among them. It is pointed out that baseline and trend data on the nature and prevalence of senior abuse are crucial to policy responses and the development of appropriate programs and services. Difficulties in assessing the scope of the phenomenon, though, are due to: problems in definitions and methodology, which create difficulties in comparing data from various countries; lack of social and familial awareness; isolation of some elders, especially migrants; elder abuse as a 'hidden issue' that usually occurs in the privacy of the home and is viewed as a family affair; limited access to institutional settings. Difficulties also exist in constructing a unifying research framework in order to study the phenomenon due to a lack of comparison groups, a lack of representative national surveys and difficulties in measurement. There is currently, however, an increase in prevalence and incidence studies from both sides of the Atlantic and especially from Europe. But while

    Lectures are the most popular form of teaching in medical education. As much as preparation and organization are key to the lecture's success, the actual presentation also depends upon the presenter's ability to reach the audience. Teaching is a lively activity. It calls for more than just offering ideas and data to an audience. It calls for direct contact with the audience, effective use of language, capability to use limited time effectively, and the ability to be entertaining. This article offers a structure to effective lecturing by highlighting the importance of voice clarity and speaking speed, approaches to using audiovisual aids, effectively using the audience to the lecture, and ways to be entertaining.

    Advancing computer technology, cost-containment pressures, and desire to make innovative improvements in medical education argue for moving learning resources to the computer. A reasonable target for such a strategy is the traditional clinical lecture. The purpose of the lecture, the advantages and disadvantages of "live" versus computer-based lectures, and the technical options in computerizing the lecture deserve attention in developing a cost-effective, complementary learning strategy that preserves the teacher-learner relationship. Based on a literature review of the traditional clinical lecture, we build on the strengths of the lecture format and discuss strategies for converting the lecture to a computer-based learning presentation.

    Lecture I deals with the behavior of particles in the nonlinear field arising from the electromagnetic interaction of colliding beams. The case treated, that of counter-rotating proton beams crossing each other at a non-zero angle, has the simple feature that the force between the beam is one dimensional. In lecture II, an analysis of the development of traveling waves on particle beams is presented. The situation studied is that of a uniform beam current in a circular accelerator and the excitation for the coherent motion is induced by the resistivity of the vacuum chamber wall. Finally, in lecture III, a description of the current accumulation process used at the proton storage rings at CERN (The ISR) is given. Particle pulses of rather low average current are injected and stored along the length and width of the vacuum chamber. The efficiency is very high and large currents (over 40 amperes) have been achieved.

    In these introductory lectures we discuss the topic of Yangian symmetry from various perspectives. Forming the classical counterpart of the Yangian and an extension of ordinary Noether symmetries, first the concept of nonlocal charges in classical, two-dimensional field theory is reviewed. We then define the Yangian algebra following Drinfel’d's original motivation to construct solutions to the quantum Yang-Baxter equation. Different realizations of the Yangian and its mathematical role as a Hopf algebra and quantum group are discussed. We demonstrate how the Yangian algebra is implemented in quantum, two-dimensional field theories and how its generators are renormalized. Implications of Yangian symmetry on the two-dimensional scattering matrix are investigated. We furthermore consider the important case of discrete Yangian symmetry realized on integrable spin chains. Finally we give a brief introduction to Yangian symmetry in planar, four-dimensional super Yang-Mills theory and indicate its impact on the dilatation operator and tree-level scattering amplitudes. These lectures are illustrated by several examples, in particular the two-dimensional chiral Gross-Neveu model, the Heisenberg spin chain and { N }=4 superconformal Yang-Mills theory in four dimensions.

Nowadays many universities and superior education institutions around the country are teaching students at the B.Sc. level and postgraduate level many topics related to acoustics, such as Architectural Acoustics, Seismology, Mechanical Vibrations, Noise Control, Audio, Audiology, Music, etc. Also many institutions have started research programs in related fields, with participation of medical doctors, psychologists, musicians, engineers, etc. Details will be given on particular topics and development.

  1. Teaching a Large Lecture Interpersonal Communication Course.

    Pearson, Judy C.

    Though lecturing reflects the outmoded view that communication consists of action rather than transaction, large lecture classes are a reality that must be engaged. An interpersonal communication course can be adapted to the lecture hall and need not include the traditional lecture as the only teaching method. Students should be allowed to…

    Nanoplasmonics or nanoscale metal-based optics is a field of science and technology with a tremendously rich and colourful history. Starting with the early works of Michael Faraday on gold nanocolloids and optically-thin gold leaf, researchers have been fascinated by the unusual optical properties displayed by metallic nanostructures. We now can enjoy selecting from over 10 000 publications every year on the topic of plasmonics and the number of publications has been doubling about every three years since 1990. This impressive productivity can be attributed to the significant growth of the scientific community as plasmonics has spread into a myriad of new directions. With 2015 being the International Year of Light, it seems like a perfect moment to review some of the most notable accomplishments in plasmonics to date and to project where the field may be moving next. After discussing some of the major historical developments in the field, this article will analyse how the most successful plasmonics applications are capitalizing on five key strengths of metallic nanostructures. This Introductory Lecture will conclude with a brief look into the future.

  4. Leveraging the Shapley Lectures

    1998-05-01

    The Shapley Lectureships are both an honor and a privilege. The program has long provided the non-specialist a rare glimpse of the latest result of astronomical investigations. Shapley Lecturers carry the banner for the most interesting of all the sciences. They share the beauty and strength of astronomy by representing the discipline to non-specialists. It is important that we contribute what we can to this program. One might benefit from the frequent travel of most astronomers. Most research trips are now covered by grant money, by university money, and by Government money. Leverage this travel. For example, many meetings are held near places with small colleges. Consider sending a Shapley brochure to the science departments before your trip. Such trips may often be used to elicit a Shapley visit. Advertise the program. When we talk about astronomy to others we help all of us to keep this science alive. I will share the results of my Shapley Visits made in the last four years while traveling for NASA and NSF.

  5. Practical strategies for effective lectures.

    PubMed

    Lenz, Peter H; McCallister, Jennifer W; Luks, Andrew M; Le, Tao T; Fessler, Henry E

    2015-04-01

    Lecturing is an essential teaching skill for scientists and health care professionals in pulmonary, critical care, and sleep medicine. However, few medical or scientific educators have received training in contemporary techniques or technology for large audience presentation. Interactive lecturing outperforms traditional, passive-style lecturing in educational outcomes, and is being increasingly incorporated into large group presentations. Evidence-based techniques range from the very simple, such as inserting pauses for audience discussion, to more technologically advanced approaches such as electronic audience response systems. Alternative software platforms such as Prezi can overcome some of the visual limits that the ubiquitous PowerPoint imposes on complex scientific narratives, and newer technology formats can help foster the interactive learning environment. Regardless of the technology, adherence to good principles of instructional design, multimedia learning, visualization of quantitative data, and informational public speaking can improve any lecture. The storyline must be clear, logical, and simplified compared with how it might be prepared for scientific publication. Succinct outline and summary slides can provide a roadmap for the audience. Changes of pace, and summaries or other cognitive breaks inserted every 15-20 minutes can renew attention. Graphics that emphasize clear, digestible data graphs or images over tables, and simple, focused tables over text slides, are more readily absorbed. Text slides should minimize words, using simple fonts in colors that contrast to a plain background. Adherence to these well-established principles and addition of some new approaches and technologies will yield an engaging lecture worth attending.

    Lester, Christopher G.

    2013-12-01

    For TASI 2011, I was asked to give a series of lectures on "Mass and Spin Measurement Techniques" with relevance to the Large Hadron Collider. This document provides a written record of those lectures - or more precisely of what I said while giving the lectures - warts and all. It is provided as my contribution to the proceedings primarily for the benefit of those who heard the lectures first hand and may wish to refer back to them. What it is not is a scientific paper or a teaching resource. Though lecture slides may be prepared in advance, what is actually said in a lecture is usually extemporaneous, may be partial, can be influenced by audience reaction, and may not even make sense without a visual record of the concomitant gesticulations of the lecturer. More worryingly, some of the statements made may be down-right false, if the lecturer's tongue is in a twist. Accordingly, these proceedings are provided without warranty of any kind - not least in respect of accuracy or impartiality. The lectures were intended to engage the audience and get them thinking about a number of topics that they had not seen before. They were not expected to be the sort of sombre or well-balanced overview of the field that one might hope to achive in a review. These proceedings are provided to jog the memory of those who saw the lectures first hand, and for little other purpose. Footnotes, where they appear, indicate text/thoughts I have added during the editing process that were not voiced during the lectures themselves. Copies of the lecture slides are inserted at approximately the locations they would have become visible in the lectures.

    These lecture notes survey some joint work with Samson Abramsky as it was presented by me at several conferences in the summer of 2005. It concerns 'doing quantum mechanics using only pictures of lines, squares, triangles and diamonds'. This picture calculus can be seen as a very substantial extension of Dirac's notation, and has a purely algebraic counterpart in terms of so-called Strongly Compact Closed Categories (introduced by Abramsky and I which subsumes my Logic of Entanglement. For a survey on the 'what', the 'why' and the 'hows' I refer to a previous set of lecture notes. In a last section we provide some pointers to the body of technical literature on the subject.

    Ydri, Badis

    The subject of matrix field theory involves matrix models, noncommutative geometry, fuzzy physics and noncommutative field theory and their interplay. In these lectures, a lot of emphasis is placed on the matrix formulation of noncommutative and fuzzy spaces, and on the non-perturbative treatment of the corresponding field theories. In particular, the phase structure of noncommutative $\\phi^4$ theory is treated in great detail, and an introduction to noncommutative gauge theory is given.

    The origin of the asymmetry between matter and anti-matter of the Universe has been one of the great challenges in particle physics and cosmology. Leptogenesis as a mechanism for generating the cosmological baryon asymmetry of the Universe has gained significant interests ever since the advent of the evidence of non-zero neutrino masses. In these lectures presented at TASI 2006, I review various realizations of leptogenesis and allude to recent developments in this subject.

  6. Three Lectures on Hadron Physics

    NASA Astrophysics Data System (ADS)

    2016-04-01

    These lectures explain that comparisons between experiment and theory can expose the impact of running couplings and masses on hadron observables and thereby aid materially in charting the momentum dependence of the interaction that underlies strong-interaction dynamics. The series begins with a primer on continuum QCD, which introduces some of the basic ideas necessary in order to understand the use of Schwinger functions as a nonperturbative tool in hadron physics. It continues with a discussion of confinement and dynamical symmetry breaking (DCSB) in the Standard Model, and the impact of these phenomena on our understanding of condensates, the parton structure of hadrons, and the pion electromagnetic form factor. The final lecture treats the problem of grand unification; namely, the contemporary use of Schwinger functions as a symmetry-preserving tool for the unified explanation and prediction of the properties of both mesons and baryons. It reveals that DCSB drives the formation of diquark clusters in baryons and sketches a picture of baryons as bound-states with Borromean character. Planned experiments are capable of validating the perspectives outlined in these lectures.

    A first-in-first-out (FIFO) microelectromechanical memory apparatus (also termed a mechanical memory) is disclosed. The mechanical memory utilizes a plurality of memory cells, with each memory cell having a beam which can be bowed in either of two directions of curvature to indicate two different logic states for that memory cell. The memory cells can be arranged around a wheel which operates as a clocking actuator to serially shift data from one memory cell to the next. The mechanical memory can be formed using conventional surface micromachining, and can be formed as either a nonvolatile memory or as a volatile memory.

    Vassilevski, P S

    2010-06-28

    The Lecture Notes are primarily based on a sequence of lectures given by the author while been a Fulbright scholar at 'St. Kliment Ohridski' University of Sofia, Sofia, Bulgaria during the winter semester of 2009-2010 academic year. The notes are somewhat expanded version of the actual one semester class he taught there. The material covered is slightly modified and adapted version of similar topics covered in the author's monograph 'Multilevel Block-Factorization Preconditioners' published in 2008 by Springer. The author tried to keep the notes as self-contained as possible. That is why the lecture notes begin with some basic introductory matrix-vector linear algebra, numerical PDEs (finite element) facts emphasizing the relations between functions in finite dimensional spaces and their coefficient vectors and respective norms. Then, some additional facts on the implementation of finite elements based on relation tables using the popular compressed sparse row (CSR) format are given. Also, typical condition number estimates of stiffness and mass matrices, the global matrix assembly from local element matrices are given as well. Finally, some basic introductory facts about stationary iterative methods, such as Gauss-Seidel and its symmetrized version are presented. The introductory material ends up with the smoothing property of the classical iterative methods and the main definition of two-grid iterative methods. From here on, the second part of the notes begins which deals with the various aspects of the principal TG and the numerous versions of the MG cycles. At the end, in part III, we briefly introduce algebraic versions of MG referred to as AMG, focusing on classes of AMG specialized for finite element matrices.

    2011-01-01

    Purpose To describe the cause and consequence of tear dysfunction related corneal disease. Design Perspective on effects of tear dysfunction on the cornea Methods Evidence is presented on the effects of tear dysfunction on corneal morphology, function and health, as well as efficacy of therapies for tear dysfunction related corneal disease. Results Tear dysfunction is a prevalent eye disease and the most frequent cause for superficial corneal epithelial disease that results in corneal barrier disruption, an irregular optical surface, light scattering, optical aberrations and exposure and sensitization of pain sensing nerve endings (nociceptors). Tear dysfunction related corneal disease causes irritation and visual symptoms, such as photophobia, blurred and fluctuating vision that may decrease quality of life. Dysfunction of one or more components of the lacrimal functional unit results in changes in tear composition, including elevated osmolarity and increased concentrations of matrix metalloproteinases, inflammatory cytokines and chemokines. These tear compositional changes promote disruption of tight junctions, alter differentiation and accelerate death of corneal epithelial cells. Conclusions Corneal epithelial disease resulting from tear dysfunction causes eye irritation and decreases visual function. Clinical and basic research has improved understanding of the pathogenesis of tear dysfunction related corneal epithelial disease, as well as treatment outcomes. PMID:22019306

    2009-01-01

    Ask any Olympian about their quest for gold and they will almost always tell you it's not really about the gold - it's all about the journey. What they learned and how they felt at the time of their successes, disappointments and failures is ultimately what challenged them to find the courage to truly believe in themselves and achieve their personal best. As dietitians, we are also like Olympians as each of us seeks personal success in our journey through life. It is no surprise that it takes knowledge and experience to become a champion. "Going for the Gold" highlights some of the milestones and challenges in the author's career and focuses on (her) two specialties, sports nutrition and nutrition and infertility, both relatively new to the dietetics field. Having a successful private practice means building a solid foundation of knowledge, excellent clinical and communication skills, finding the courage to "think outside of the box", a compassion for others and a strong work ethic to fulfill goals that benefit both clients and the profession. As the author recounts her journey, dietitians are reminded that there is no straight path to success, and in their quest for gold not to forget to give back...to their profession, their family, their country and their environment.

  14. Adolphe Abrahams memorial lecture, 1988. Exercise and lifestyle change.

    PubMed Central

    Shephard, R J

    1989-01-01

    While the evidence for a clustering of health habits is not particularly strong, there are both pedagogic and economic arguments in favour of a multifaceted approach to health education. The present review thus examines the impact of regular physical exercise upon other forms of health behaviour, testing the extent to which an activity programme can be a catalyst of improved lifestyle in both primary and secondary preventive therapy. The conceptual framework of health promotion is examined with particular reference to the models of Skinner, Becker, Fishbein, Triandis and Rokeach. Certain differences are noted between the decision to exercise and the marketing decisions for which Fishbein's model was originally designed. Nevertheless, in its later modifications, it provides a basic framework for understanding how human lifestyle is shaped. Theoretical mechanisms are suggested whereby exercise could influence such behaviours as cigarette smoking, alcohol consumption and drug usage, seat-belt usage, hypertension, body mass, lipid profile, promiscuous sexual behaviour, the carrying of lethal weapons, and acceptance of regular preventive medical examinations. The empirical evidence from both cross-sectional and longitudinal experiments shows a relatively weak association between exercise habits and other desirable forms of health behaviour. Moreover, it is arguable that other forms of health intervention such as smoking withdrawal or dieting might be equally effective as a primary change agent, and much of the observed association between exercise and other health habits could be attributable to a common dependence on demographic and socio-economic factors. On the other hand, the apparent weakness of associations may arise in part from difficulties in measuring both habitual physical activity and other forms of health behaviour, with a resultant attenuation of correlations. Possibly, a stronger association between exercise participation and other favourable health habits would be uncovered if attention were focused upon those forms of endurance exercise currently thought to enhance cardiac health. Given that moderate endurance exercise is also positive and pleasant advice, further examination of the potential of multifaceted but exercise-centered health promotion programmes appears warranted.

    Trauma and the management of injuries have changed considerably over the past century. A sound understanding of the factors that generate injuries and sophisticated systems that can be accessed immediately are now in place in most of the United States. The concept of a team approach to the management of multiple system injuries using specialists from all disciplines has resulted in the reduction of morbidity and mortality. Although many of the challenges of managing the trauma patient have been overcome, there are still a number of exciting areas that lend themselves to ongoing research. These changing perspectives allow for many exciting challenges for the trauma team. PMID:1507246

  17. Dohi Memorial Lecture. New aspects of cutaneous mosaicism.

    PubMed

    Happle, Rudolf

    2002-11-01

    The concept of cutaneous mosaicism has today been proven at the cellular level in at least fifteen different skin disorders. We can distinguish five different patterns of mosaicism, including the phylloid pattern and the lateralization pattern. Etiologically, cutaneous mosaics can be divided into two large categories, epigenetic mosaicism and genomic mosaicism. All forms of epigenetic mosaicism known so far, including the various patterns of X-inactivation, appear to be caused by the action of retrotransposons. A new concept is functional autosomal mosaicism transmittable through the action of retrotransposons, which has been described in mice and dogs and may explain, for example, the familial occurrence of pigmentary mosaicism along the Blaschko lines in human skin. Among the examples of mosaicism of autosomal lethal mutations, phylloid hypomelanosis is a recently recognized neurocutaneous entity caused by mosaic trisomy 13. Possible examples of a type 2 segmental manifestation now include at least fifteen different autosomally dominant skin disorders. This phenomenon is most frequently found in glomangiomatosis, cutaneous leiomyomatosis, and disseminated superficial actinic porokeratosis. Recently proposed examples of didymosis (twin spotting) include cutis tricolor, paired patches of excessive or absent involvement in Darier disease, and didymosis aplasticosebacea characterized by coexistent aplasia cutis congenita and nevus sebaceus. To the list of possible examples of paradominant inheritance, cutis marmorata telangiectatica congenita and speckled lentiginous nevus syndrome have now been added. Revertant mosaicism giving rise to unaffected skin areas in autosomally recessive cutaneous traits will certainly likewise be recognized more often when clinicians are bearing this concept in mind. Such cases can be taken as examples of "natural gene therapy".

  18. Cummings Memorial Lecture - 1975. The market basket: food for thought.

    PubMed

    Deichman, W B

    1975-06-01

    The world food crisis is as critical today as when it was debated at the 1974 World Food Conference in Rome. Since the United States and Canada-and to a lesser extent, Australia and New Zealand-lead in the production of corn, wheat and soybeans, the North American "bread basket" has become the "market basket" of the world. For welfare, economic, and political reasons, our energies, resources, and deliberations must be expanded toward optimum production of wholesome food products. I do not recommend that we permit food additives in "questionably" safe or excessive concentrations in our agricultural products. I do recommend, however, that tolerance limits for food additives be established based on a comprehensive review of all contributing factors-the world food crisis and the rational interpretation of both positive and negative animal data as they relate to man. As Dr. Herbert Stokinger put it so aptly: "Avoid the establishment of unnecessarily severe standards." 2. Funds for research and teaching of food and nutrition should be greatly increased, so that all who can read and write may be made aware of the daily dietary requirements for the maintenance of good health. 3. Unsubstantiated scare tactics in publications of the scientific and lay press can only lead to well-intended but often emotionally-inspired restrictions, ordinances, and laws. Such decisions are likely to either under- or over-define the requirements and standards for food additives and other chemicals which are important to the well-being of the populace.

    The article aims to identify some of the challenges for future training of orthodontics and subsequently the delivery of orthodontic care. Clearly, in any aspect of future prediction, the precision is simply that of an art. However, it is hoped that some of the reported bibliography will allow those that wish to, the opportunity to look further. The global economy is undergoing a significant period of rationalization and luxury items such as Orthodontics may become less publicly funded. In order to maintain the specialty as one in which clinicians are appropriately trained, there needs to be a reconsideration of the way in which education is delivered and assessment assured. This presentation will identify possible challenges and identify a strategy to consider, construct and deliver a rational way forward in a positive way that ensures that the strengths of how the profession has developed are maintained.

    In February 1924, at the invitation of C. A. Chant, Russell presented a set of 14 public lectures on the state of astronomy and astrophysics. Designed to be inspirational, they also reveal Russell's contemporary views on the state of astrophysics as well as his sense of proper practice in astronomy. During his visit, Russell was interviewed by local reporters who asked his opinion about building a large observatory, one of Chant's major projects. What Russell had to say about such ventures did not please Chant one bit.

    The physiology of paracellular permeation of ions and solutes in the kidney is pivotally important but poorly understood. Claudins are the key components of the paracellular pathway. Defects in claudin function result in a broad range of renal diseases, including hypomagnesemia, hypercalciuria and nephrolithiasis. This review describes recent findings on the physiological function of claudins underlying paracellular transport mechanisms with a focus on renal Ca2+ handling. We have uncovered a molecular mechanism underlying paracellular Ca2+ transport in the thick ascending limb of Henle (TAL) that involves the functional interplay of three important claudin genes: claudin-14, -16 and -19, all of which are associated with human kidney diseases with hypercalciuria, nephrolithiasis and bone mineral loss. The Ca2+ sensing receptor (CaSR) signaling in the kidney has long been a mystery. By analyzing small non-coding RNA molecules in the kidney, we have uncovered a novel microRNA based signaling pathway downstream of CaSR that directly regulates claudin-14 gene expression and establishes the claudin-14 molecule as a key regulator for renal Ca2+ homeostasis. The molecular cascade of CaSR-microRNAs-claudins forms a regulatory loop to maintain proper Ca2+ homeostasis in the kidney. PMID:22504740

  5. Lectures on Dark Matter Physics

    NASA Astrophysics Data System (ADS)

    Lisanti, Mariangela

    Rotation curve measurements from the 1970s provided the first strong indication that a significant fraction of matter in the Universe is non-baryonic. In the intervening years, a tremendous amount of progress has been made on both the theoretical and experimental fronts in the search for this missing matter, which we now know constitutes nearly 85% of the Universe's matter density. These series of lectures provide an introduction to the basics of dark matter physics. They are geared for the advanced undergraduate or graduate student interested in pursuing research in high-energy physics. The primary goal is to build an understanding of how observations constrain the assumptions that can be made about the astro- and particle physics properties of dark matter. The lectures begin by delineating the basic assumptions that can be inferred about dark matter from rotation curves. A detailed discussion of thermal dark matter follows, motivating Weakly Interacting Massive Particles, as well as lighter-mass alternatives. As an application of these concepts, the phenomenology of direct and indirect detection experiments is discussed in detail.

    Increasing application of information technology including web-based lectures and live-lecture recording appears to have many advantages for undergraduate nursing education. These include greater flexibility, opportunity for students to review content on demand and the improved academic management of increasing class sizes without significant increase in physical infrastructure. This study performed a quasi-experimental comparison between two groups of nursing students undertaking their first anatomy and physiology course, where one group was also provided access to streaming of recorded copies of the live lectures and the other did not. For the course in which recorded lectures were available student feedback indicated overwhelming support for such provision with 96% of students having accessed recorded lectures. There was only a weak relationship between access of recorded lectures and overall performance in the course. Interestingly, the nursing students who had access to the recorded lectures demonstrated significantly poorer overall academic performance (P < 0.001). Although this study did not specifically control for student demographics or other academic input, the data suggests that provision of recorded lectures requires improved and applied time management practices by students and caution on the part of the academic staff involved.

    NASA Astrophysics Data System (ADS)

    Dudley, J. M.; Kwan, A. M.

    1996-06-01

    The subject of quantum electrodynamics (QED) was the subject of QED—The Strange Theory of Light and Matter, the popular book by Richard Feynman which was published by Princeton University Press in 1985. On p. 1, Feynman makes passing reference to the fact that the book is based on a series of general lectures on QED which were, however, first delivered in New Zealand. At Auckland University, these lectures were delivered in 1979, as the Sir Douglas Robb lectures, and videotapes of the lectures are held by the Auckland University Physics Department. We have carried out a detailed examination of these videotapes, and we discuss here the major differences between the original Auckland lectures and the published version. We use selected quotations from the lectures to show that the original lectures provide additional insight into Feynman's character, and have great educational value.

    Fullwood, R.

    1992-03-01

    These lecture notes for criticality safety are prepared for the training of Department of Energy supervisory, project management, and administrative staff. Technical training and basic mathematics are assumed. The notes are designed for a two-day course, taught by two lecturers. Video tapes may be used at the options of the instructors. The notes provide all the materials that are necessary but outside reading will assist in the fullest understanding. The course begins with a nuclear physics overview. The reader is led from the macroscopic world into the microscopic world of atoms and the elementary particles that constitute atoms. The particles, their masses and sizes and properties associated with radioactive decay and fission are introduced along with Einstein`s mass-energy equivalence. Radioactive decay, nuclear reactions, radiation penetration, shielding and health-effects are discussed to understand protection in case of a criticality accident. Fission, the fission products, particles and energy released are presented to appreciate the dangers of criticality. Nuclear cross sections are introduced to understand the effectiveness of slow neutrons to produce fission. Chain reactors are presented as an economy; effective use of the neutrons from fission leads to more fission resulting in a power reactor or a criticality excursion. The six-factor formula is presented for managing the neutron budget. This leads to concepts of material and geometric buckling which are used in simple calculations to assure safety from criticality. Experimental measurements and computer code calculations of criticality are discussed. To emphasize the reality, historical criticality accidents are presented in a table with major ones discussed to provide lessons-learned. Finally, standards, NRC guides and regulations, and DOE orders relating to criticality protection are presented.

  3. [THE DISCUSSION CONCERNING THE PLACE OF LECTURES AND COMPULSORY LECTURE ATTENDANCE IN MEDICAL EDUCATION].

    PubMed

    Reis, Shmuel

    2016-04-01

    Luder shows that there is a lack of correlation between lecture attendance in medical school and examination performance, and thus draws attention to a discourse concerning the place of lectures and lecture attendance enforcement in 2015 and beyond. The paper addresses 4 questions: First, what is the current place of the traditional lecture in the education of medical students? Second, are there alternatives to this format of teaching? Third, what are the educational consequences of mandating lecture attendance; and fourth, should there be such enforcement? The author discusses these questions and concludes that lectures should be used sparingly, after a careful evaluation that they have an added value over learning away from the classroom. Furthermore, that there are clear guidelines on how to make the traditional lecture enhanced and educationally effective, as well as alternatives such as the "flipped classroom", e-learning and more to lectures. In addition, that lectures frequently drive learning negatively and enforcing attendance in Israel entails serious unintended consequences such as a need to monitor attendance, and a host of disciplinary adverse reactions. Finally, that besides lecture efficiency and economy (when having added value) one reason to consider compulsory attendance, may be when poor attendance negatively influences teachers morale.

  9. Making lectures memorable: A cognitive perspective.

    PubMed

    Afzal, Azam; Babar, Shazia

    2016-08-01

    Lectures have been a cornerstone of medical education since the introduction of a discipline based curricular model more than two hundred years ago. Recently this instructional strategy has come under criticism because of its reliance on passive learning. There are still many medical schools that cover content predominantly through lectures due to its feasibility. With the introduction of the flipped classrooms, lectures have been given a new lease of life. Improving cognitive imprinting during lectures would enhance retrieval and promote long term storage. Simplifying the content reduces the cognitive load of the information being received and makes it more meaningful hence more memorable. To make learning memorable, rehearsal should be built into the sessions. With the exponential increase in online learning, the need for online learning technologies will require a generation of a large amount of asynchronous video content which should ideally be truly meaningful and memorable, and inspirational to our students.

    SciTech Connect

    Yost, G.P.

    1984-09-01

    These notes are based on a set of statistics lectures delivered at Imperial College to the first-year postgraduate students in High Energy Physics. They are designed for the professional experimental scientist. We begin with the fundamentals of probability theory, in which one makes statements about the set of possible outcomes of an experiment, based upon a complete a priori understanding of the experiment. For example, in a roll of a set of (fair) dice, one understands a priori that any given side of each die is equally likely to turn up. From that, we can calculate the probability of any specified outcome. We finish with the inverse problem, statistics. Here, one begins with a set of actual data (e.g., the outcomes of a number of rolls of the dice), and attempts to make inferences about the state of nature which gave those data (e.g., the likelihood of seeing any given side of any given die turn up). This is a much more difficult problem, of course, and one's solutions often turn out to be unsatisfactory in one respect or another.

    Teaching and learning activities in the dental clinic or hospital are a challenging area for students as well as teachers. With various teaching methodologies being used in dental schools around the world, gaining greater understanding of students' attitudes toward these methodologies would be useful for dental educators. The objective of this study was to explore the preferences of dental students in India about various aspects of lecture courses. A structured survey consisting of ten closed-ended questions was developed, and 2,680 undergraduate students from forty-three dental schools in India were approached via e-mail with a follow-up postal mailing. Of these, 1,980 students responded, for a response rate of 73.8 percent. Most of the students reported preferring lectures with the aid of PowerPoint and chalkboard. They preferred morning lectures from 8 am to 10 am for a maximum of thirty to forty minutes for each lecture, and they preferred to receive information about the lecture topic in advance. The students said that delivery of clinical demonstrations was beneficial after the lectures, and they preferred learning-based rather than exam-oriented education. The respondents also said that attendance should be made compulsory and that numerical marking of examinations should not be replaced by a grading system.

    Educational research shows that students learn best in an environment with emphasis on teamwork, problem-solving, and hands-on experience. Still professors spend the majority of their time with students in the traditional lecture-hall setting where the combination of large classes and limited time prevents sufficient student-teacher interaction to foster an active learning environment. Can modern computer technology be used to provide "lecture-type" information to students via the World Wide Web? If so, will that help professors make better and/or different use of their scheduled time with the students? Answering these questions was the main motivation for the Extra-Solar Planet Project. The Extra-Solar Planet Project was designed to test the effectiveness of a lecture available to the student on the World Wide Web (Web-Lecture) and to engage the students in an active learning environment were their use the information presented in the Web-Lecture. The topic of the Web-Lecture was detection of extra-solar planets and the project was implemented into an introductory astronomy course at University of Wisconsin Madison in the spring of 2004. The Web-Lecture was designed to give an interactive presentation of synchronized video, audio and lecture notes. It was created using the eTEACH software developed at the University of Wisconsin Madison School of Engineering. In my talk, I will describe the project, show excerpts of the Web-Lecture, and present assessments of student learning and results of student evaluations of the web-lecture format.

    2010-06-01

    This study tested the possibility that interactive lectures explicitly based on activating learners' prior knowledge and driven by a series of logical questions might enhance the effectiveness of lectures. A class of 54 students doing the respiratory system course in the second year of the Bachelor of Medicine and Bachelor of Surgery program in my university was randomized to two groups to receive one of two types of lectures, "typical" lectures (n = 28, 18 women and 10 men) or "constructivist" lectures (n = 26, 19 women and 7 men), on the same topic: the regulation of respiration. Student pretest scores in the two groups were comparable (P > 0.1). Students that received the constructivist lectures did much better in the posttest conducted immediately after the lectures (6.8 +/- 3.4 for constructivist lectures vs. 4.2 +/- 2.3 for typical lectures, means +/- SD, P = 0.004). Although both types of lectures were well received, students that received the constructivist lectures appeared to have been more satisfied with their learning experience. However, on a posttest conducted 4 mo later, scores obtained by students in the two groups were not any different (6.9 +/- 3 for constructivist lectures vs. 6.9 +/- 3.7 for typical lectures, P = 0.94). This study adds to the increasing body of evidence that there is a case for the use of interactive lectures that make the construction of knowledge and understanding explicit, easy, and enjoyable to learners.

    A cohort of first-year biology students was surveyed regarding their opinions and viewing habits for live and recorded lectures. Most respondents (87%) attended live lectures as a rule (attenders), with 66% attending more than two-thirds of the lectures. In contrast, only 52% accessed recordings and only 13% viewed more than two-thirds of the available recordings. Respondents regarded lectures as efficient for information delivery (75%), and 89% enjoyed live lectures because they were useful for learning (89%), understanding coursework (94%), and keeping up with the subject (93%). Lecture enjoyment was driven less by entertainment (34%) or interaction with the lecturers (47%), although most students preferred an entertaining lecturer to a factual expert (72%). Exam marks were positively correlated with the number of lectures attended (P < 0.001) and negatively correlated with the number of recordings viewed (P < 0.05), although marks were similar for lecture attenders and nonattenders (P > 0.05). Lecture attenders mostly missed lectures to complete assessments during the same week (68%), whereas nonattenders were more likely to miss lectures due to outside commitments or preference for study from books or recorded lectures (P < 0.001). Recordings were used to replace missed lectures (64%), rather than for revision, and were viewed mostly alone (96%) in one sitting (65%). Only 22% of respondents agreed that some lectures could be replaced by recordings, but 59% agreed with having some videoconference lectures from experts on another campus. Overall, this cohort showed a clear preference for live lectures over recordings, with limited support for synchronous videoconference lectures.

    2015-01-01

    Audience response systems (‘clickers’) are frequently used to promote participation in large lecture classes, and evidence suggests that they convey a number of benefits to students, including improved academic performance and student satisfaction. The limitations of these systems (such as limited access and cost) can be overcome using students’ personal electronic devices, such as mobile phones, tablets and laptops together with text message, web- or app-based polling systems. Using questionnaires, we compare student perceptions of clicker and smartphone based polling systems. We find that students prefer interactive lectures generally, but those that used their own device preferred those lectures over lectures using clickers. However, device users were more likely to report using their devices for other purposes (checking email, social media etc.) when they were available to answer polling questions. These students did not feel that this distracted them from the lecture, instead, concerns over the use of smartphones centred around increased battery usage and inclusivity for students without access to suitable technology. Our results suggest that students generally preferred to use their own devices over clickers, and that this may be a sensible way to overcome some of the limitations associated with clickers, although issues surrounding levels of distraction and the implications for retention and recall of information need further investigation.

Recent Findings: Advances in functional neuroimaging and refinement of neuropsychological and bedside assessment tools continue to support a model of multiple memory systems that are distinct yet complementary and to support the potential for one system to be engaged as a compensatory strategy when a counterpart system fails. Summary: Episodic memory, the ability to recall personal episodes, is the subtype of memory most often perceived as dysfunctional by patients and informants. Medial temporal lobe structures, especially the hippocampal formation and associated cortical and subcortical structures, are most often associated with episodic memory loss. Episodic memory dysfunction may present acutely, as in concussion; transiently, as in transient global amnesia (TGA); subacutely, as in thiamine deficiency; or chronically, as in Alzheimer disease. Semantic memory refers to acquired knowledge about the world. Anterior and inferior temporal lobe structures are most often associated with semantic memory loss. The semantic variant of primary progressive aphasia (svPPA) is the paradigmatic disorder resulting in predominant semantic memory dysfunction. Working memory, associated with frontal lobe function, is the active maintenance of information in the mind that can be potentially manipulated to complete goal-directed tasks. Procedural memory, the ability to learn skills that become automatic, involves the basal ganglia, cerebellum, and supplementary motor cortex. Parkinson disease and related disorders result in procedural memory deficits. Most memory concerns warrant bedside cognitive or neuropsychological evaluation and neuroimaging to assess for specific neuropathologies and guide treatment. PMID:26039844

  4. On performing concepts during science lectures

    NASA Astrophysics Data System (ADS)

    Pozzer-Ardenghi, Lilian; Roth, Wolff-Michael

    2007-01-01

    When lecturing, teachers make use of both verbal and nonverbal communication. What is called teaching, therefore, involves not only the words and sentences a teacher utters and writes on the board during a lesson, but also all the hands/arms gestures, body movements, and facial expressions a teacher performs in the classroom. All of these communicative modalities constitute resources that are made available to students for making sense of and learning from lectures. Yet in the literature on teaching science, these other means of communication are little investigated and understood - and, correspondingly, they are undertheorized. The purpose of this position paper is to argue for a different view of concepts in lectures: they are performed simultaneously drawing on and producing multiple resources that are different expressions of the same holistic meaning unit. To support our point, we provide examples from a database of 26 lectures in a 12th-grade biology class, where the human body was the main topic of study. We analyze how different types of resources - including verbal and nonverbal discourse and various material artifacts - interact during lectures. We provide evidence for the unified production of these various sense-making resources during teaching to constitute a meaning unit, and we emphasize particularly the use of gestures and body orientations inside this meaning unit. We suggest that proper analyses of meaning units need to take into account not only language and diagrams but also a lecturer's pointing and depicting gestures, body positions, and the relationships between these different modalities. Scientific knowledge (conceptions) exists in the concurrent display of all sense-making resources, which we, following Vygotsky, understand as forming a unit (identity) of nonidentical entities.

  5. The William Ellery Hale Lectures at the National Academy of Sciences, 1914-1918

    In 1913 George Ellery Hale, together with his brother William and sister Martha pledged 1000 per year for five years to inaugurate an annual series of lectures in memory of their father. The series would explore "the general subject of Evolution, which is designed to give a clear and comprehensive outline of the broad features of inorganic and organic evolution in the light of recent research." (NAS Annual Report 1914 p. 24). Here we look briefly at how evolution entered into astronomical thinking in the late 19th Century, and specifically into George Ellery Hale's universe as an organizing principle for research and institutional development, as illustrated by this lecture series, which brought the likes of Ernest Rutherford, W. W. Campbell and T. C. Chamberlin to speak before scientific Washington.

  6. Intrinsic deficiencies of lectures as a teaching method.

    Lectures were, still are and seem to remain a dominant form of teaching, despite an increased research and use of other methods of teaching and leverage of technology aimed at improving teaching results and efficiency. Learning, as the result of a lecture, greatly depends on the subject, the competence and abilities of the lecturer as well as on other transient causes. However, lectures also have some intrinsic deficiencies as a teaching method pertinent to their very nature. In order to fully understand the teaching value of lectures and their role and proper use in educational systems, their deficiencies have been studied in a theoretical analysis from the perspective of cognitive learning theories. Fifteen deficiencies have been identified and clustered in three categories based on root causes of deficiencies: synchronicity problems, time constraint and individual student abilities, needs and knowledge. These findings can be used to adjust expected learning outcomes of lectures, to properly (re)design lecture content and process and to design other learning and teaching activities that would compensate and complement lectures. Recommendations are given on replacing and amending lectures with other instructional methods, amending lectures in the course of delivery with additional content and tools and complementing lectures after delivery with content, tools and activities. Suggestions on the use of information technology that could substitute, reduce or eliminate at least some of the deficiencies are made. Lecture captures seem to be valuable supplement for live lectures compensating in all three categories of deficiencies. Suggestions and directions for further research are given.

    Euler, Manfred

    2007-06-01

    Compared to Ernst Mach's influence on the conceptual development of physics, his efforts to popularize science and his reflections on science literacy are known to a much lesser degree. The approach and the impact of Mach's popular scientific lectures are discussed in view of today's problems of understanding science. The key issues of Mach's popular scientific lectures, reconsidered in the light of contemporary science, still hold a high potential in fascinating a general audience. Moreover, Mach's grand theme, the relation of the physical to the psychical, is suited to contribute to a dialogue between different knowledge cultures, e.g. science and humanities.

  9. Memory protection

    NASA Technical Reports Server (NTRS)

    Denning, Peter J.

    1988-01-01

    Accidental overwriting of files or of memory regions belonging to other programs, browsing of personal files by superusers, Trojan horses, and viruses are examples of breakdowns in workstations and personal computers that would be significantly reduced by memory protection. Memory protection is the capability of an operating system and supporting hardware to delimit segments of memory, to control whether segments can be read from or written into, and to confine accesses of a program to its segments alone. The absence of memory protection in many operating systems today is the result of a bias toward a narrow definition of performance as maximum instruction-execution rate. A broader definition, including the time to get the job done, makes clear that cost of recovery from memory interference errors reduces expected performance. The mechanisms of memory protection are well understood, powerful, efficient, and elegant. They add to performance in the broad sense without reducing instruction execution rate.

    The Medical Physics and Radiation Protection communities lost one of their true pioneers in May, 2014 with the passing of Warren K. Sinclair, Ph.D. He received his Doctorate in Physics at the University of London, U.K. He was a fellow of the Institute of Physics and a Certified Health Physicist. After a number of posts at Hospitals and Universities in the U.K. and New Zealand, he became the Head, Physics Department at the M.D. Anderson Hospital, Houston, TX. He held a number of academic physics positions with the University of Texas, Austin at the main campus and at the Postgraduate School of Medicine, Houston. He later served as a Senior Biophysicist, Division Director, and then Associate Laboratory Director for Biomedical Division Director, and then Associate Laboratory Director for Biomedical and Environmental Research at the Argonne National Laboratory, IL. He had additional academic appointments at the University of California, Berkeley; Northern Illinois University; the University of Illinois (Chicago Circle Campus); and the University of Chicago. Warren was a charter member of the AAPM and a leader in many communities: President of the AAPM from 1960 to 1961 and the Journal Editor from 1964 to 1969, the 2nd President of the NCRP from 1977 to 1991, and the President of the Radiation Research Society from 1978 to 1979. His many awards included the William D. Coolidge Award in 1986. Even this barely scratches the surface of the many other organizations he served with and influenced including the ICRP, IOP, RSNA, SNM, and UNSCEAR. His research interests resulted in publications from 1948 to the 1990s in many aspects (physical and biological) of radiotherapy and the effects of ionizing radiation in general, leading to early definitions of RBE values for megavoltage radiotherapy as well as contributing to the development of the modern framework for radiation protection worldwide. Warren was not a retiring person and even after moving to NCRP President Emeritus status continued to provide advice and comments on publications and to mentor others until the time of his passing. Sadly, Warren’s long-time wife Joy passed away in December, 2014 but he is survived by his son Bruce and daughter Roslyn, 2 grandchildren and 4 great-grandchildren.

    The Medical Physics community lost one of its prominent leaders in April, 2013 with the passing of Donald D. Tolbert, PhD. He received his Doctorate at the University of Kansas followed by post Doctoral training at Florida State University and the University of Wisconsin. He was Chief of Radiation Therapy Medical Physics at the University of Wisconsin Hospital for 7 years before relocating to Honolulu Hawaii, where he founded the consulting group Mid-Pacific Medical Physics. Don was a leader in both the AAPM and the ACR, chairing the Professional Council and the Commission on Medical Physics. He was active on the AAPM Board of Directors and a member of the ACR Board of Chancellors. Dr. Tolbert's approach to the difficult problems of the times was admired and respected by colleagues in Medical Physics, Radiation Oncology, and Diagnostic Radiology. He always rose above the heated political rhetoric and led the discussion to higher ground. His wisdom was continually sought to solve complicated problems. Following retirement, he returned to homes in Kansas and Colorado, devoting his time to writing about coping with diabetes and providing support for Seniors in Beloit Kansas. Don is survived by his wife, Mattie, his 3 children and 5 grandchildren. He will be greatly missed.

    Background Lectures are good for presenting information and providing explanations, but because they lack active participation they have been neglected. Methods Students' experiences were evaluated after exposing them to the use of voting during lectures in their paediatrics course. Questions were delivered to the students taking paediatrics course. Thirty-six students out of the total of 40 (90%) attended the opening lecture, at which the first survey concerning previous experiences of lectures was performed. Thirty-nine students (98%) answered the second series of questions at the end of the paediatrics course. Results Most of the students felt that voting improved their activity during lectures, enhanced their learning, and that it was easier to make questions during lectures than earlier. Conclusions The students gained new, exciting insights much more often during the paediatrics course than before. We as teachers found that voting during lectures could easily overcome some of the obstacles of good lecturing. PMID:14678571

  15. Cueing others' memories.

    PubMed

    Tullis, Jonathan G; Benjamin, Aaron S

    2015-05-01

    Many situations require us to generate external cues to support later retrieval from memory. For instance, we create file names in order to cue our memory to a file's contents, and instructors create lecture slides to remember what points to make during classes. We even generate cues for others when we remind friends of shared experiences or send colleagues a computer file that is named in such a way so as to remind them of its contents. Here we explore how and how well learners tailor retrieval cues for different intended recipients. Across three experiments, subjects generated verbal cues for a list of target words for themselves or for others. Learners generated cues for others by increasing the normative cue-to-target associative strength but also by increasing the number of other words their cues point to, relative to cues that they generated for themselves. This strategy was effective: such cues supported higher levels of recall for others than cues generated for oneself. Generating cues for others also required more time than generating cues for oneself. Learners responded to the differential demands of cue generation for others by effortfully excluding personal, episodic knowledge and including knowledge that they estimate to be broadly shared.

  3. Flashbulb Memories

    Hirst, William; Phelps, Elizabeth A.

    2015-01-01

    We review and analyze the key theories, debates, findings, and omissions of the existing literature on flashbulb memories (FBMs), including what factors affect their formation, retention, and degree of confidence. We argue that FBMs do not require special memory mechanisms and are best characterized as involving both forgetting and mnemonic distortions, despite a high level of confidence. Factual memories for FBM-inducing events generally follow a similar pattern. Although no necessary and sufficient factors straightforwardly account for FBM retention, media attention particularly shapes memory for the events themselves. FBMs are best characterized in term of repetitions, even of mnemonic distortions, whereas event memories evidence corrections. The bearing of this literature on social identity and traumatic memories is also discussed. PMID:26997762

Modern computers have very large main memories, but need automatic solutions to the relocation and protection problems. Virtual memory serves this need as well and is thus useful in computers of all sizes. The history of the idea is traced, showing how it has become a widespread, little noticed feature of computers today.

  7. BOOK REVIEW: Feynman Lectures on Gravitation

    NASA Astrophysics Data System (ADS)

    Feynman, Richard P.; Morinigo, Fernando B.; Wagner, William G.

    2003-05-01

    In the early 1960s Feynman lectured to physics undergraduates and, with the assistance of his colleagues Leighton and Sands, produced the three-volume classic Feynman Lectures in Physics. These lectures were delivered in the mornings. In the afternoons Feynman was giving postgraduate lectures on gravitation. This book is based on notes compiled by two students on that course: Morinigo and Wagner. Their notes were checked and approved by Feynman and were available at Caltech. They have now been edited by Brian Hatfield and made more widely available. The book has a substantial preface by John Preskill and Kip Thorne, and an introduction entitled 'Quantum Gravity' by Brian Hatfield. You should read these before going on to the lectures themselves. Preskill and Thorne identify three categories of potential readers of this book. 1. Those with a postgraduate training in theoretical physics. 2. 'Readers with a solid undergraduate training in physics'. 3. 'Admirers of Feynman who do not have a strong physics background'. The title of the book is perhaps misleading: readers in category 2 who think that this book is an extension of the Feynman Lectures in Physics may be disappointed. It is not: it is a book aimed mainly at those in category 1. If you want to get to grips with gravitation (and general relativity) then you need to read an introductory text first e.g. General Relativity by I R Kenyon (Oxford: Oxford University Press) or A Unified Grand Tour of Theoretical Physics by Ian D Lawrie (Bristol: IoP). But there is no Royal Road. As pointed out in the preface and in the introduction, the book represents Feynman's thinking about gravitation some 40 years ago: the lecture course was part of his attempts to understand the subject himself, and for readers in all three categories it is this that makes the book one of interest: the opportunity to observe how a great physicist attempts to tackle some of the hardest challenges of physics. However, the book was written 40

    An account of episodic memories is developed that focuses on the types of knowledge they represent, their properties, and the functions they might serve. It is proposed that episodic memories consist of "episodic elements," summary records of experience often in the form of visual images, associated to a "conceptual frame" that provides a…

    2016-01-01

    From the Newsline Editor: The Highlights Lecture, presented at the closing session of each SNMMI Annual Meeting, was originated and delivered for more than 30 years by Henry N. Wagner, Jr., MD. Beginning in 2010, the duties of summarizing selected significant presentations at the meeting were divided annually among 4 distinguished nuclear and molecular medicine subject matter experts. The 2015 Highlights Lectures were delivered on June 10 at the SNMMI Annual Meeting in Baltimore, MD. Umar Mahmood, MD, PhD, a professor of radiology at Massachusetts General Hospital (Boston, MA), spoke on oncology highlights from the meeting’s sessions. Because of its length, the oncology presentation will be divided between 2 Newsline issues. Note that in the following summary, numerals in brackets represent abstract numbers as published in The Journal of Nuclear Medicine [2015;56:suppl 3). PMID:26526798

  11. Lectures series in computational fluid dynamics

    NASA Technical Reports Server (NTRS)

    Thompson, Kevin W.

    1987-01-01

    The lecture notes cover the basic principles of computational fluid dynamics (CFD). They are oriented more toward practical applications than theory, and are intended to serve as a unified source for basic material in the CFD field as well as an introduction to more specialized topics in artificial viscosity and boundary conditions. Each chapter in the test is associated with a videotaped lecture. The basic properties of conservation laws, wave equations, and shock waves are described. The duality of the conservation law and wave representations is investigated, and shock waves are examined in some detail. Finite difference techniques are introduced for the solution of wave equations and conservation laws. Stability analysis for finite difference approximations are presented. A consistent description of artificial viscosity methods are provided. Finally, the problem of nonreflecting boundary conditions are treated.

  12. Ida Mann Lecture 2007: Planet eye.

    PubMed

    McMenamin, Paul G

    2008-10-01

    The concept for this lecture arose as a consequence of the invitation from the College to give the 'Ida Mann Lecture' arriving recently after I had enjoyed the beautiful David Attenborough series 'Planet Earth' on television. It struck me as not too fanciful an idea at the time to make an analogy between 'Planet Earth' and the eye and thus the idea of giving an Attenborough-like tour of the ocular microenvironments and making the analogy between various immune cells in the eye and wildlife on planet Earth was born. I could only hope that in some small measure my presentation would inspire and educate an audience of ophthalmologists on the amazing world of ocular immune cells in the way that David Attenborough enraptures millions of television viewers with his beautiful series.

  13. Polarization in heavy-ion reactions. [Lectures

    SciTech Connect

    Fick, D.

    1983-08-01

    Determination of the polarization and spin alignment of reaction products emitted from heavy ion reactions should provide a sensitive test of reaction mechanisms. Techniques for producing both polarized beams and polarized targets are advancing rapidly. At the Oak Ridge National Laboraotry interest in this field has lead to the design and construction of a laser optically pumped polarized target by illuminating a supersonic gas jet. This target, which is mounted in the scattering chamber of a magnetic spectrometer, will be used to observe effects when deformed polarized targets are bombarded by heavy ions. Mutual research interests led to the invitation of Professor Fick, a pioneer in heavy ion polarization research who recently reviewed the status of this field, to Oak Ridge. While at ORNL he presented a series of lectures on this subject. Notes from these lectures are presented. (WHK)

  14. Innovative Astronomy Teaching Using Lecture Activities

    Grundstrom, E.; Baines, E.; Gies, D. R.

    2005-05-01

    Interactive learning is crucial to the retention of knowledge (especially scientific) and learning in astronomy is no exception. We have developed three classroom activities that cover common astronomy concepts that are difficult to master: Phases of the Moon, Eclipses, and Impacts and Probability. These activities were planned to integrate into an introductory astronomy course for non-majors at Georgia State University. Each activity consists of hands-on models that small groups of students may utilize to complete a conceptual exercise that requires them to make predictions. We envision these three activities as prototypes for lecture activities throughout the introductory astronomy sequence. We report here on the scope of the activities and their effectiveness in the lecture tutorial context. This research has been sponsored by the Georgia Partnership for Reform In Science and Mathematics (PRISM) which is funded by the National Science Foundation.

    A picture is worth a thousand words-This doesn't only apply to everyday life but also to the natural sciences. It is, therefore, probably not by chance that the historical beginning of modern natural sciences very much coincides with the invention of light microscopy. S. W. Hell shows in his Nobel Lecture that the diffraction resolution barrier has been overcome by using molecular state transitions (e.g. on/off) to make nearby molecules transiently discernible.

  16. Memory conformity affects inaccurate memories more than accurate memories.

    PubMed

    Wright, Daniel B; Villalba, Daniella K

    2012-01-01

    After controlling for initial confidence, inaccurate memories were shown to be more easily distorted than accurate memories. In two experiments groups of participants viewed 50 stimuli and were then presented with these stimuli plus 50 fillers. During this test phase participants reported their confidence that each stimulus was originally shown. This was followed by computer-generated responses from a bogus participant. After being exposed to this response participants again rated the confidence of their memory. The computer-generated responses systematically distorted participants' responses. Memory distortion depended on initial memory confidence, with uncertain memories being more malleable than confident memories. This effect was moderated by whether the participant's memory was initially accurate or inaccurate. Inaccurate memories were more malleable than accurate memories. The data were consistent with a model describing two types of memory (i.e., recollective and non-recollective memories), which differ in how susceptible these memories are to memory distortion.

  17. Combining traditional anatomy lectures with e-learning activities: how do students perceive their learning experience?

    Wieser, Heike; Waldboth, Simone; Mischo-Kelling, Maria

    2016-01-01

    Objectives The purpose of this study was to investigate how students perceived their learning experience when combining traditional anatomy lectures with preparatory e-learning activities that consisted of fill-in-the-blank assignments, videos, and multiple-choice quizzes. Methods A qualitative study was conducted to explore changes in study behaviour and perception of learning. Three group interviews with students were conducted and thematically analysed. Results Data was categorized into four themes: 1. Approaching the course material, 2. Understanding the material, 3. Consolidating the material, and 4. Perceived learning outcome.  Students appreciated the clear structure of the course, and reported that online activities encouraged them towards a first engagement with the material. They felt that they were more active during in-class sessions, described self-study before the end-of-term exam as easier, and believed that contents would remain in their memories for a longer time. Conclusions By adjusting already existing resources, lectures can be combined fairly easily and cost-effectively with preparatory e-learning activities. The creation of online components promote well-structured courses, can help minimize ‘student passivity’ as a characteristic element of lectures, and can support students in distributing their studies throughout the term, thus suggesting enhanced learning. Further research work should be designed to confirm the afore-mentioned findings through objective measurements of student learning outcomes. PMID:26897012

  18. The Trieste Lecture of John Stewart Bell

    Bassi, Angelo; Carlo Ghirardi, Gian

    2007-03-01

    Delivered at Trieste on the occasion of the 25th Anniversary of the International Centre for Theoretical Physics, 2 November 1989 The video of this lecture is available here. Please see the PDF for the transcript of the lecture. General remarks by Angelo Bassi and GianCarlo Ghirardi During the autumn of 1989 the International Centre for Theoretical Physics, Trieste, celebrated the 25th anniversary of its creation. Among the many prestigious speakers, who delivered extremely interesting lectures on that occasion, was the late John Stewart Bell. All lectures have been recorded on tape. We succeeded in getting a copy of John's lecture. In the lecture, many of the arguments that John had lucidly stressed in his writings appear once more, but there are also extremely interesting new remarks which, to our knowledge, have not been presented elsewhere. In particular he decided, as pointed out by the very choice of the title of his lecture, to call attention to the fact that the theory presents two types of difficulties, which Dirac classified as first and second class. The former are those connected with the so-called macro-objectification problem, the latter with the divergences characterizing relativistic quantum field theories. Bell describes the precise position of Dirac on these problems and he stresses appropriately how, contrary to Dirac's hopes, the steps which have led to a partial overcoming of the second class difficulties have not helped in any way whatsoever to overcome those of the first class. He then proceeds to analyse the origin and development of the Dynamical Reduction Program and draws attention to the problems that still affect it, in particular that of a consistent relativistic generalization. When the two meetings Are there quantum jumps? and On the present status of Quantum Mechanics were organized in Trieste and Losinj (Croatia), on 5 10 September 2005, it occurred to us that this lecture, which has never been published, might represent an

    2012-07-01

    Critical care pharmacology education is crucial to safe patient care for nurses orienting to specialized areas. Although traditionally taught as a classroom lecture, it is important to consider effectiveness of alternative methods for education. This study provided experimentally derived evidence regarding effectiveness of blended versus traditional lecture for critical care pharmacology education. Regardless of learner demographics, the findings determined no significant differences in cognitive learning outcomes or learner satisfaction between blended versus lecture formats.

  1. [Surgical frontal lecture. Still important for teaching students?].

    PubMed

    Wierlemann, A; Baur, J; Germer, C T

    2013-10-01

    In times of manifold digital learning resources open to public access lectures in surgery still play a major role in medical training. It is a platform for discussion with the medical teacher and provides the opportunity to create a vivid learning experience by showing live operations via video streaming and inviting patients to the lectures. When then change in paradigm is achieved from pure knowledge transfer to cross-linkage of knowledge, the surgical lecture will be a major future keystone in medical education, where the lecturer can reach the students with his own passion for the field of expertise and get them interested in surgery.

    2011-07-01

    Much like the world described in Abbott’s Flatland, graphene is a two-dimensional object. And, as “Flatland” is “a romance of many dimensions,” graphene is much more than just a flat crystal. It possesses a number of unusual properties which are often unique or superior to those in other materials. In this brief lecture I would like to explain the reason for my (and many other people’s) fascination with this material, and invite the reader to share some of the excitement I’ve experienced while researching it.

  7. Fear Memory.

    PubMed

    Izquierdo, Ivan; Furini, Cristiane R G; Myskiw, Jociane C

    2016-04-01

    Fear memory is the best-studied form of memory. It was thoroughly investigated in the past 60 years mostly using two classical conditioning procedures (contextual fear conditioning and fear conditioning to a tone) and one instrumental procedure (one-trial inhibitory avoidance). Fear memory is formed in the hippocampus (contextual conditioning and inhibitory avoidance), in the basolateral amygdala (inhibitory avoidance), and in the lateral amygdala (conditioning to a tone). The circuitry involves, in addition, the pre- and infralimbic ventromedial prefrontal cortex, the central amygdala subnuclei, and the dentate gyrus. Fear learning models, notably inhibitory avoidance, have also been very useful for the analysis of the biochemical mechanisms of memory consolidation as a whole. These studies have capitalized on in vitro observations on long-term potentiation and other kinds of plasticity. The effect of a very large number of drugs on fear learning has been intensively studied, often as a prelude to the investigation of effects on anxiety. The extinction of fear learning involves to an extent a reversal of the flow of information in the mentioned structures and is used in the therapy of posttraumatic stress disorder and fear memories in general.

  8. Lecture capturing assisted teaching and learning experience

    NASA Astrophysics Data System (ADS)

    Chen, Li

    2015-03-01

    When it comes to learning, a deep understanding of the material and a broadband of knowledge are equally important. However, provided limited amount of semester time, instructors often find themselves struggling to reach both aspects at the same time and are often forced to make a choice between the two. On one hand, we would like to spend much time to train our students, with demonstrations, step by step guidance and practice, to develop strong critical thinking skills and problem-solving skills. On the other hand, we also would like to cover a wide range of content topics to broaden our students' understanding. In this presentation, we propose a working scheme that may assist to achieve these two goals at the same time without sacrificing either one. With the help of recorded and pre-recorded lectures and other class materials, it allows instructors to spend more class time to focus on developing critical thinking skills and problem-solving skills, and to apply and connect principle knowledge with real life phenomena. It also allows our students to digest the material at a pace they are comfortable with by watching the recorded lectures over and over. Students now have something as a backup to refer to when they have random mistakes and/or missing spots on their notes, and hence take more ownership of their learning. Advanced technology have offered flexibility of how/when the content can be delivered, and have been assisting towards better teaching and learning strategies.

  9. Introductory lecture: basic quantities in model biomembranes.

    PubMed

    Nagle, John F

    2013-01-01

    One of the many aspects of membrane biophysics dealt with in this Faraday Discussion regards the material moduli that describe energies at a supramolecular level. This introductory lecture first critically reviews differences in reported numerical values of the bending modulus K(C), which is a central property for the biologically important flexibility of membranes. It is speculated that there may be a reason that the shape analysis method tends to give larger values of K(C) than the micromechanical manipulation method or the more recent X-ray method that agree very well with each other. Another theme of membrane biophysics is the use of simulations to provide exquisite detail of structures and processes. This lecture critically reviews the application of atomic level simulations to the quantitative structure of simple single component lipid bilayers and diagnostics are introduced to evaluate simulations. Another theme of this Faraday Discussion was lateral heterogeneity in biomembranes with many different lipids. Coarse grained simulations and analytical theories promise to synergistically enhance experimental studies when their interaction parameters are tuned to agree with experimental data, such as the slopes of experimental tie lines in ternary phase diagrams. Finally, attention is called to contributions that add relevant biological molecules to bilayers and to contributions that study the exciting shape changes and different non-bilayer structures with different lipids.

    Saville, Bryan K; Zinn, Tracy E; Neef, Nancy A; Van Norman, Renee; Ferreri, Summer J

    2006-01-01

    Interteaching is a new method of classroom instruction that is based on behavioral principles but offers more flexibility than other behaviorally based methods. We examined the effectiveness of interteaching relative to a traditional form of classroom instruction—the lecture. In Study 1, participants in a graduate course in special education took short quizzes after alternating conditions of interteaching and lecture. Quiz scores following interteaching were higher than quiz scores following lecture, although both methods improved performance relative to pretest measures. In Study 2, we also alternated interteaching and lecture but counterbalanced the conditions across two sections of an undergraduate research methods class. After each unit of information, participants from both sections took the same test. Again, test scores following interteaching were higher than test scores following lecture. In addition, students correctly answered more interteaching-based questions than lecture-based questions on a cumulative final test. In both studies, the majority of students reported a preference for interteaching relative to traditional lecture. In sum, the results suggest that interteaching may be an effective alternative to traditional lecture-based methods of instruction. PMID:16602385

    Gülpinar, Mehmet Ali; Yeğen, Berrak C

    2005-11-01

    In order to enhance the quality of integration of physiological basic concepts with clinical sciences and to facilitate problem solving skills, a 'structured integrated interactive' two-hour block lecture on growth hormone physiology was implemented. A template showing the central regulation of growth hormone release and its peripheral effects was developed as an advanced organizer. Based on this template, new information was presented. Student feedback demonstrated that the lecture, based on the expository teaching model and enhanced by different forms of question and problem solving activities, was successful and interactive. It was also more motivating and was able to keep the attention of the students in relatively higher levels throughout the lecture. Furthermore, students felt that they had made important gains in transferable problem solving skills and this opinion was supported by their performance in clinical cases. These findings reinforced the idea that systematic incorporation of active learning strategies into lectures may minimize many of the weaknesses of traditional lectures.

  10. A trial of patient-oriented problem-solving system for immunology teaching in China: a comparison with dialectic lectures

    PubMed Central

    2013-01-01

    Background The most common teaching method used in China is lecturing, but recently, efforts have been widely undertaken to promote the transition from teacher-centered to student-centered education. The patient-oriented problem-solving (POPS) system is an innovative teaching-learning method that permits students to work in small groups to solve clinical problems, promotes self-learning, encourages clinical reasoning and develops long-lasting memory. To our best knowledge, however, POPS has never been applied in teaching immunology in China. The aim of this study was to develop POPS in teaching immunology and assess students’ and teachers’ perception to POPS. Methods 321 second-year medical students were divided into two groups: I and II. Group I, comprising 110 students, was taught by POPS, and 16 immunology teachers witnessed the whole teaching process. Group II including the remaining 211 students was taught through traditional lectures. The results of the pre- and post-test of both groups were compared. Group I students and teachers then completed a self-structured feedback questionnaire for analysis before a discussion meeting attended only by the teachers was held. Results Significant improvement in the mean difference between the pre- and post-test scores of those in Groups I and II was seen, demonstrating the effectiveness of POPS teaching. Most students responded that POPS facilitates self-learning, helps them to understand topics and creates interest, and 88.12% of students favored POPS over simple lectures. Moreover, while they responded that POPS facilitated student learning better than lectures, teachers pointed out that limited teaching resources would make it difficult for wide POPS application in China. Conclusions While POPS can break up the monotony of dialectic lectures and serve as a better teaching method, it may not be feasible for the current educational environment in China. The main reason for this is the relative shortage of teaching

    In these lectures I review the standard hot big-bang cosmology, emphasizing its successes, its shortcomings, and its major challenge-a detailed understanding of the formation of structure in the Universe. I then discuss the motivations for and the fundamentals of inflationary cosmology, particularly emphasizing the quantum origin of metric (density and gravity-wave) perturbations. Inflation addresses the shortcomings of the standard cosmology and provides the initial data'' for structure formation. I conclude by addressing the implications of inflation for structure formation, evaluating the various cold dark matter models in the light of the recent detection of temperature anisotropies in the cosmic background radiation by COBE. In the near term, the study of structure formation offers a powerful probe of inflation, as well as specific inflationary models.

    Henn, Johannes M.

    2015-04-01

    Over the last year significant progress was made in the understanding of the computation of Feynman integrals using differential equations (DE). These lectures give a review of these developments, while not assuming any prior knowledge of the subject. After an introduction to DE for Feynman integrals, we point out how they can be simplified using algorithms available in the mathematical literature. We discuss how this is related to a recent conjecture for a canonical form of the equations. We also discuss a complementary approach that is based on properties of the space-time loop integrands, and explain how the ideas of leading singularities and d-log representations can be used to find an optimal basis for the DE. Finally, as an application of these ideas we show how single-scale integrals can be bootstrapped using the Drinfeld associator of a DE.

    2014-02-01

    With the proliferation of new affordable recording technologies, many universities have begun offering students recordings of live lectures as a part of the course resources. We conducted a survey to investigate why some students choose to attend lectures in person rather than simply watching the recordings online, and how students view the two types of lectures. Students attending live lectures in five large undergraduate mathematics lecture streams were invited to respond to the survey. A significant number of respondents viewed recorded lecture as superfluous to their needs which were met upon attending live lecture. Surprisingly, however, an equally large number of students described compelling reasons for watching both live and recorded lectures. A number of factors were identified as determining students' perceptions of live and recorded lectures as competing or complementary: personal learning styles, study habits, esteem for the lecturer, and the possibility of interaction in the lecture.

  20. Do-It-Yourself Whiteboard-Style Physics Video Lectures

    Douglas, Scott Samuel; Aiken, John Mark; Greco, Edwin; Schatz, Michael; Lin, Shih-Yin

    2017-01-01

    Video lectures are increasingly being used in physics instruction. For example, video lectures can be used to "flip" the classroom, i.e., to deliver, via the Internet, content that is traditionally transmitted by in-class lectures (e.g., presenting concepts, working examples, etc.), thereby freeing up classroom time for more interactive instruction. To date, most video lectures are live lecture recordings or screencasts. The hand-animated "whiteboard" video is an alternative to these more common styles and affords unique creative opportunities such as stop-motion animation or visual "demonstrations" of phenomena that would be difficult to demo in a classroom. In the spring of 2013, a series of whiteboard-style videos were produced to provide video lecture content for Georgia Tech introductory physics instruction, including flipped courses and a MOOC. This set of videos (which also includes screencasts and live recordings) can be found on the "Your World is Your Lab" YouTube channel. In this article, we describe this method of video production, which is suitable for an instructor working solo or in collaboration with students; we explore students' engagement with these videos in a separate work. A prominent example of whiteboard animation is the "Minute Physics" video series by Henry Reich, whose considerable popularity and accessible, cartoony style were the original inspiration for our own video lectures.

    We describe Interactive Lecture Experiments (ILE), which build on Interactive Lecture Demonstrations proposed by Sokoloff and Thornton (2004) and extends it by providing students with the opportunity to analyze experiments demonstrated in the lecture outside of the classroom. Real time experimental data is collected, using Logger Pro combined with the digital video technology. This data is uploaded to the Internet and made available to the students for further analysis. Student learning is assessed in the following lecture using conceptual questions (clickers). The goal of this project is to use ILE to make large lectures more interactive and promote student interest in science, critical thinking and data analysis skills. We report on the systematic study conducted using the Colorado Learning Attitudes about Science Survey, Force Concept Inventory, open-ended physics problems and focus group interviews to determine the impact of ILE on student academic achievement, motivation and attitudes towards physics. Three sections of students (750 students) experienced four ILE experiments. The surveys were administered twice and academic results for students who experienced the ILE for a particular topic were compared to the students, from a different section, who did not complete the ILE for that topic. Additional qualitative data on students’ attitudes was collected using open ended survey questions and interviews. We will present preliminary conclusions about the role of ILEs as an effective pedagogy in large introductory physics courses. Sokoloff, D.R. and R.K. Thornton (2004).

    2013-01-01

    Memory can be divided into several types, although all of them involve three successive processes: encoding, storage, and retrieval. In terms of the duration of retention, neurologists classify memory into immediate, recent, and remote memories, whereas psychologists classify memory into short-term and long-term memories. In terms of the content, episodic, semantic, and procedural memories are considered to be different types of memory. Furthermore, researchers on memory have proposed relatively new concepts of memory, i.e., working memory and prospective memory. This article first provides explanations for these several types of memory. Next, neuropsychological characteristics of amnesic syndrome are briefly outlined. Finally, how several different types of memory are affected (or preserved) in patients with amnesic syndrome is described.

    In a 2-year project, we developed and trialled a mode of lecturing professional development amongst staff in our department of mathematics. Theoretically grounded in Schoenfeld's resources, orientations, and goals (ROG) model of teacher action, a group met regularly to discuss both the video excerpts of themselves lecturing along with written pre- and post-lecture statements of their "ROGs". We found evidence of improved teaching performance but more interestingly, identified key aspects of our practice and of undergraduate mathematics that received repeated attention and developed further theoretical insight into lecturer behaviour in mathematics. The trial has been successful enough to be expanded into further groups that now constitute a professional development culture within our department.

    NASA Astrophysics Data System (ADS)

    Herrick, Brad Jay

    Students continue to arrive at universities with poor study and time management skills: they are not proactive in their studies while professors are not willing to hold them accountable for their shortcomings. The result is a 'dumbing down' of the course. This can be defeated by student preparation prior to attending lecture, especially in very large-lecture classrooms (N>400). In fact, it provides a process to 'dumb up' the course. A Web-based system for providing content specific lecture preparations (termed 'Previews') was developed and tested in three courses in a large southwestern research institution. Significance was found in final course achievement by treatment levels, including variations by the total number of participations in the lecture preparations. Method of implementation and results are discussed, including future considerations.

    PubMed

    Oermann, Marilyn H

    2004-01-01

    Many creative teaching strategies have been developed in recent years in nursing and other fields to promote active learning. These strategies foster development of problem solving, critical thinking, and communication skills, and they encourage students to work collaboratively with peers. However, in nurse educators' rush to embrace active learning, lecture has been viewed negatively by some faculty. Rather than positioning active learning against lecture, another approach is to integrate active learning within lecture, gaining the benefits of both methods. An integrated approach also takes into consideration the situation of teaching large groups of students. This article examines benefits of an integrated approach to teaching and presents strategies for active learning intended for use with lecture.

  2. First Steps Toward Increasing Student Engagement During Lecture

    Have you tried to repurpose materials you've gotten from another lecturer or publisher that you thought could express a concept exceptionally well, only to find when you used the same materials, they did not have the dramatic effect on your students you desired? It would be easy to conclude that student apathy is to blame. But, if students listening to your lecture take on the same bored appearance and passive disposition often observed when you are showing a video, consider whether your instructional approach is designed to intellectually engage students. An information-download lecture has often been described as…the process by which the teacher's notes get transferred into students' notebooks without passing through the brains of either. That brilliant set of lecture materials that you thought would be perfect might need to be adjusted to meet the learning styles of your students to actively engage them in developing conceptual understanding.

  6. Lectures on probability and statistics. Revision

    Yost, G.P.

    1985-06-01

    These notes are based on a set of statistics lectures delivered at Imperial College to the first-year postgraduate students in High Energy Physics. They are designed for the professional experimental scientist. They begin with the fundamentals of probability theory, in which one makes statements about the set of possible outcomes of an experiment, based upon a complete a priori understanding of the experiment. For example, in a roll of a set of (fair) dice, one understands a priori that any given side of each die is equally likely to turn up. From that, we can calculate the probabilty of any specified outcome. They finish with the inverse problem, statistics. Here, one begins with a set of actual data (e.g., the outcomes of a number of rolls of the dice), and attempts to make inferences about the state of nature which gave those data (e.g., the likelihood of seeing any given side of any given die turn up). This is a much more difficult problem, of course, and one's solutions often turn out to be unsatisfactory in one respect or another. Hopefully, the reader will come away from these notes with a feel for some of the problems and uncertainties involved. Although there are standard approaches, most of the time there is no cut and dried ''best'' solution - ''best'' according to every criterion.

  7. Reconsidering the lecture in modern veterinary education.

    Those teaching in the higher-education environment are now increasingly meeting with larger cohorts of students. The result is additional pressure on the resources available and on the teacher and learners. Against this backdrop, discussions and reflections took place between a practitioner, within a UK veterinary school, and an educational researcher with extensive experience in observing teaching in veterinary medicine. The result was an examination of the lecture as a method of teaching to consider how to resolve identified challenges. The focus of much of the literature is on technical aspects of teaching and learning, reverting to a range of tips to resolve particular issues recognized in large-group settings. We suggest that while these tips are useful, they will only take a practitioner so far. To be able to make a genuine connection to learners and help them connect directly to the discipline, we need to take account of the emotional aspects of our role as teachers, without which, delivery of knowledge may be undermined.

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

    Heron, Paula R. L.

    2015-06-01

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

  9. PDF Lecture Materials for Online and ``Flipped'' Format Astronomy Courses

    2013-04-01

    Online astronomy courses typically rely on students reading the textbook and/or a set of text-based lecture notes to replace the “lecture” material. However, many of our students report that this is much less engaging than in-person lectures, especially given the amount of interactive work such as “think-pair-share” problems done in many astronomy classes. Students have similarly criticized direct lecture-capture. To address this, we have developed a set of PowerPoint-style presentations with embedded lecture audio combined with prompts for student interaction including think-pair-share questions. These are formatted PDF packages that can be used on a range of different computers using free software. The presentations are first developed using Microsoft PowerPoint software. Audio recordings of scripted lectures are then synchronized with the presentations and the entire package is converted to PDF using Adobe Presenter. This approach combines the ease of editing that PowerPoint provides along with the platform-independence of PDF. It's easy to add, remove, or edit individual slides as needed, and PowerPoint supports internal links so that think-pair-share questions can be inserted with links to feedback based on the answers selected. Modern PDF files support animated visuals with synchronized audio and they can be read using widely available free software. Using these files students in an online course can get many of the benefits of seeing and hearing the course material presented in an in-person lecture format. Students needing extra help in traditional lecture classes can use these presentations to help review the materials covered in lecture. Finally, the presentations can be used in a “flipped” format in which students work through the presentations outside of class time while spending the “lecture” time on in-class interaction.

    The depth and breadth of pathophysiology content, foundational for nursing practice, is well suited for traditional lecture delivery. Use of creative strategies can deepen students' understanding while respecting students' diverse talents and ways of learning. The authors discuss strategies they used, including case studies, questions asked during lecture using immediate feedback technology, creative visual demonstrations, group pathophysiologic theory projects, short videos, and games, to enhance students' understanding and retention of content.

We will cover in the present lectures more or less the same general field, but certainly there will be a lot more results to be discussed now than four years ago.

  12. It's not the done thing: social norms governing students' passive behaviour in undergraduate mathematics lectures

    2011-12-01

    Students often play a passive role in large-scale lectures in undergraduate mathematics courses: they observe the lecturer demonstrate mathematical procedures, but they rarely engage in authentic mathematical activity themselves. This study uses semi-structured interviews of undergraduate students to investigate the implicit and explicit social norms and expectations that influence students to maintain their passive roles during lectures. Students were aware that their passivity was influenced by social norms, but perceived these norms as necessary for allowing the lecturer to get through the content in the allotted lecture time, while enabling students to avoid being publicly embarrassed in the lecture. However, the students appreciated opportunities to work on examples in small groups during lectures. We argue that the success of small group interactions during large-scale lectures depends on students and lecturers establishing supportive social norms, and adjusting their lecture goals from 'covering the content' to 'developing mathematical understanding'.

  13. The clinical role of nurse lecturers: Past, present, and future.

    Barrett, David

    2007-07-01

    The clinical role of nurse lecturers has been the subject of much debate since the transfer of nurse education into Higher Education Institutions within the United Kingdom. This article provides a critical evaluation of the clinical role of nurse lecturers in terms of policy drivers and strategies for implementing national guidelines. Policies from the initiation of Project 2000, through to recent consultation documents on the support of students in practice, are evaluated. Formal aspects of the nurse lecturer remit, such as link tutor and personal supervisor roles, are discussed in terms of their impact on clinical practice. There is also a brief review of the development of the lecturer practitioner role as a bridge between education and practice. The fundamental arguments in support of nurse lecturers maintaining a clinical role in practice are analysed. This analysis includes consideration of the concept of 'clinical credibility' in terms of the impact on teaching and the closure of the theory-practice gap. The article concludes with suggestions for strategies to resolve the ongoing debate surrounding the clinical role of nurse lecturers. These recommendations include a review of staff:student ratios in nurse education, re-evaluation of the need for a clinical role, and the use of innovative recruitment and development strategies by higher education institutions.

    We conducted team-based learning (TBL) with interdisciplinary lectures as a part of "Introduction to Pharmacy", divided among the pharmacy department's six pharmacist education curricula in the first semester. The interdisciplinary lecture is led by seven lecturers, each specializing in one area: cell biology, biochemistry, chemistry, public health pharmacology, pharmacokinetics, and clinical science. This lecture's purpose is to demonstrate to the students that all field subjects relate to each other and they must learn the basic science subjects to understand pharmaceutical sciences. The TBL contents have two themes, "cancer" and "aspirin", each of which had two lectures, each 90 minutes long and were conducted using TBL as expansive learning. On receiving knowledge of a wide range of fields in one lecture, a small number of students indicated that they were unable to understand the contents very well. However, in the questionnaire about TBL, many students reported "I have understood" and "I have enjoyed studying" using TBL, especially group readiness assessment test (GRAT). By incorporating TBL, they reported "increasing eagerness to learn pharmacy". Overall, students seem to have accepted TBL favorably, but they still find peer review difficult. We believe that their discomfort with peer review results from their unfamiliarity in evaluating others, and the time before the evaluation is short because TBL is conducted only twice.

    2014-01-01

    Objective. To compare the impact of 2 different teaching and learning methods on student mastery of learning objectives in a pharmacotherapy module in the large classroom setting. Design. Two teaching and learning methods were implemented and compared in a required pharmacotherapy module for 2 years. The first year, multiple interactive mini-cases with inclass individual assessment and an abbreviated lecture were used to teach osteoarthritis; a traditional lecture with 1 inclass case discussion was used to teach gout. In the second year, the same topics were used but the methods were flipped. Student performance on pre/post individual readiness assessment tests (iRATs), case questions, and subsequent examinations were compared each year by the teaching and learning method and then between years by topic for each method. Students also voluntarily completed a 20-item evaluation of the teaching and learning methods. Assessment. Postpresentation iRATs were significantly higher than prepresentation iRATs for each topic each year with the interactive mini-cases; there was no significant difference in iRATs before and after traditional lecture. For osteoarthritis, postpresentation iRATs after interactive mini-cases in year 1 were significantly higher than postpresentation iRATs after traditional lecture in year 2; the difference in iRATs for gout per learning method was not significant. The difference between examination performance for osteoarthritis and gout was not significant when the teaching and learning methods were compared. On the student evaluations, 2 items were significant both years when answers were compared by teaching and learning method. Each year, students ranked their class participation higher with interactive cases than with traditional lecture, but both years they reported enjoying the traditional lecture format more. Conclusion. Multiple interactive mini-cases with an abbreviated lecture improved immediate mastery of learning objectives compared to

  17. Lecture-Capture Software and the Teaching of Soils

    NASA Astrophysics Data System (ADS)

    Brevik, Eric C.

    2014-05-01

    Several companies now offer software that can record academic lectures and place them on password-protected course websites for future review by students. Using lecture-capture software offers several advantages for the instructor and the students, including: 1) The ability for students who miss class for legitimate reasons (e.g., participation in school-sanctioned extra-curricular activities, illness or family emergencies) to get lecture materials by logging into the class website. This provides these students with a more complete exposure to the material than simply copying a classmate's notes. 2) The instructor is able to direct students who miss class for legitimate reasons to the recorded lecture rather than needing to spend time going over the material with those students and that recap does not end up being rushed. 3) The ability to address course conflicts for graduating seniors by allowing them to take the lecture portion of the class via recorded lecture. 4) Students who desire more in-depth learning are able to go back to selected portions of previous lectures to review and reconsider a topic of discussion or to fill in vague sections of their notes. There are also potential disadvantages to the use of lecture-capture software, including: 1) decreased student attendance in class because they feel they can watch class later at a time of their own choosing, 2) additional time spent by the instructor dealing with the technology, and 3) problems with hardware or software during class time that prevents recording a given day's lecture. These problems can often be addressed or justified relatively easily. If problem 1 is of concern to an instructor it can be addressed by blocking online access to individual students who have a poor record of class attendance. In the case of problem 2, the extra time spent with the technology is often offset by a reduction in time answering questions from students who have missed class. Problem 3 does happen, but in the author

  18. The Transuranium Elements: Early History (Nobel Lecture)

    McMillan, E. M.

    1951-12-12

    In this talk the author tells of the circumstances that led to the discovery of neptunium, the first element beyond uranium, and the partial identification of plutonium, the next one beyond that. The part of the story that lies before 1939 has already been recounted here in the Nobel lectures of Fermi and Hahn. Rather the author starts with the discovery of fission by Hahn and Strassmann. News of this momentous discovery reached Berkeley early in 1939. The staff of the Radiation Laboratory was put into a state of great excitement and several experiments of a nature designed to check and extend the announced results were started, using ionization chambers and pulse amplifiers, cloud chambers, chemical methods, and so forth. The author decided to do an experiment of a very simple kind. When a nucleus of uranium absorbs a neutron and fission takes place, the two resulting fragments fly apart with great violence, sufficient to propel them through air or other matter for some distance. This distance, called the "range", is quantity of some interest, and the author undertook to measure it by observing the depth of penetration of the fission fragments in a stack of thin aluminum foils. The fission fragments came from a thin layer of uranium oxide spread on a sheet of paper, and exposed to neutrons from a beryllium target bombarded by 8 Mev deuterons in the 37-inch cyclotron. The aluminum foils, each with a thickness of about half a milligram per square centimeter, were stacked like the pages of a book in immediate contact with the layer of uranium oxide. After exposure to the neutrons, the sheets of aluminum were separated and examined for radioactivity by means of an ionization chamber. The fission fragments of course are radioactive atoms, and their activity is found where they stop.

The first voltage, preferably less than 0 volts, different from said second voltage. The semiconductor wire is optically transparent and has a bandgap less than the energy produced by the light source. The light source is optically connected to the semiconductor wire. The first electrode and the second electrode are electrically insulated from each other and said semiconductor wire.

  3. Order-memory and association-memory.

    PubMed

    Caplan, Jeremy B

    2015-09-01

    Two highly studied memory functions are memory for associations (items presented in pairs, such as SALT-PEPPER) and memory for order (a list of items whose order matters, such as a telephone number). Order- and association-memory are at the root of many forms of behaviour, from wayfinding, to language, to remembering people's names. Most researchers have investigated memory for order separately from memory for associations. Exceptions to this, associative-chaining models build an ordered list from associations between pairs of items, quite literally understanding association- and order-memory together. Alternatively, positional-coding models have been used to explain order-memory as a completely distinct function from association-memory. Both classes of model have found empirical support and both have faced serious challenges. I argue that models that combine both associative chaining and positional coding are needed. One such hybrid model, which relies on brain-activity rhythms, is promising, but remains to be tested rigourously. I consider two relatively understudied memory behaviours that demand a combination of order- and association-information: memory for the order of items within associations (is it William James or James William?) and judgments of relative order (who left the party earlier, Hermann or William?). Findings from these underexplored procedures are already difficult to reconcile with existing association-memory and order-memory models. Further work with such intermediate experimental paradigms has the potential to provide powerful findings to constrain and guide models into the future, with the aim of explaining a large range of memory functions, encompassing both association- and order-memory.

    The interaction between amygdala-driven and hippocampus-driven activities is expected to explain why emotion enhances episodic memory recognition. However, overwhelming behavioral evidence regarding the emotion-induced enhancement of immediate and delayed episodic memory recognition has not been obtained in humans. We found that the recognition performance for event memory differs from that for emotional memory. Although event recognition deteriorated equally for episodes that were or were not emotionally salient, emotional recognition remained high for only stimuli related to emotional episodes. Recognition performance pertaining to delayed emotional memory is an accurate predictor of the context of past episodes.

    Background and Objectives: Medical/dental colleges in Northern India cater to students with diverse backgrounds, mother tongues, levels of comprehending English, and intelligence levels. This study was conducted to identify lecture strategy and teaching aid best suited for North Indian dental and medical students. It was conducted in two parts – 1. Survey of teachers’ and students’ opinion to obtain their preferences in teaching-learning practices followed in a conventional lecture, and 2. Comparison of students’ performances after a single trial lecture with different groups of students, using different teaching aids (TAs). Materials and Methods: Opinions of 33 faculty teaching first year dental/ medical students and 506 volunteer students (320 female) were compiled. Students were divided into four groups. A single trial lecture was held with each group (on the same topic, using identical lesson plan, by the same teacher) using a different teaching aid with each group. Lecture strategy was designed according to students’ preferences (as obtained from opinion survey) regarding language of instruction and the number of mental breaks. TAs used with different groups were chalk and board (C&B), PowerPoint (PPT), overhead projector (OHP), and a combination of C&B and PPT. Pre- and post-tests using multiple choice questions were conducted with each group. Results of post-test questionnaire and feedback from faculty attending the lecture were assessed for students’ satisfaction and attentiveness in all four groups. Results: Survey results indicated that although 97.6% students believed they had good/fair proficiency in English, 83.6% preferred being taught in a combination of English and Hindi; 44.3% students preferred C&B, 40.1% preferred PPT and 15.6% preferred the use of OHP as TA. After conducting a trial lecture with different TAs with each group, more than 90% students expressed satisfaction with the TA used for that group. Significantly better

  6. Attention span during lectures: 8 seconds, 10 minutes, or more?

    PubMed

    Bradbury, Neil A

    2016-12-01

    In the current climate of curriculum reform, the traditional lecture has come under fire for its perceived lack of effectiveness. Indeed, several institutions have reduced their lectures to 15 min in length based upon the "common knowledge" and "consensus" that there is a decline in students' attention 10-15 min into lectures. A review of the literature on this topic reveals many discussions referring to prior studies but scant few primary investigations. Alarmingly, the most often cited source for a rapid decline in student attention during a lecture barely discusses student attention at all. Of the studies that do attempt to measure attention, many suffer from methodological flaws and subjectivity in data collection. Thus, the available primary data do not support the concept of a 10- to 15-min attention limit. Interestingly, the most consistent finding from a literature review is that the greatest variability in student attention arises from differences between teachers and not from the teaching format itself. Certainly, even the most interesting material can be presented in a dull and dry fashion, and it is the job of the instructor to enhance their teaching skills to provide not only rich content but also a satisfying lecture experience for the students.

    As Lord Kelvin observed: "If you can not measure it, you can not improve it." Measurement is the start of all scientific knowledge. Measurement sets science apart from metaphysical speculation. Measurement is not the last word in science but it is the first. In hydrology, progress in measurement methods has not been as rapid as in sister Earth sciences such as meteorology, oceanography, or geodynamics. Of the hundreds of scientific satellites, only one has hydrology as its main mission at the time of this writing (hopefully two at the time of the lecture). The closest we come to a large measurement infrastructure is an experimental watershed. Nothing wrong with an experimental watershed but it does not compare to, say, the Square Kilometer Array with its exabyte per day output. We tend to give up quickly because we will always have to work with effective parameters that can not be measured directly. We will never be able to know all stomata in a tree and how they interact with the turbulent flow through the canopy. We will never be able to know all pores in a soil and how water moves through them. But also effective parameters have to be measured, be it indirectly. No surprise then that my presentation will focus on measurements in hydrology and water management. First, the fun aspects and intellectual challenges of developing new measurement methods will be highlighted. From weighing trees to listening to rain to taking a stream's temperature, we have had many interesting experiences over the years. Second, the balance between model complexity and data availability will be discussed. Although there is a generally recognized need for parsimonious models in hydrology, formal approaches to finding the correct level of complexity are rare. Some complexity control approaches, borrowed from computer science, will be presented together with a hydrological application. As it turns out, these methods seem to predict nicely the onset of equifinality or the statistical

    Many communities have a cemetery, war memorial, public sculpture or old historic buildings that are an important part of the historic record of that community. Such monuments celebrate achievements, commemorate people who died serving their country, or a prominent former member of the local community. Monuments and memorials can trace the histiry of settlement within a community. After a number of years researching cemeteries and memorials, primarily in western Canada my research partner, a historian, and I, a geoscience educator,have documented many monuments and memorials that are succumbing to basic weathering processes. Original design choices can be dictated by cost, material availability, access to transportation and emotions. Climate, type of material, construction methods, technology used and long-term maintenance can all have significant impacts on the sustainability of that material record. Over the last five years we have given many lectures and workshops on the nature of cemeteries to family historians, historical societies and classroom educators. These workshops and lectures focus on developing a better ommunity understanding of the fragility of the record. Field trips by students of all ages can contextualize both geology and history. Seeing local monumanets can facilitate the development of a sense of time and place as well as an appreciation of the environmental impacts and the longevity of the record. For the earth science student documentation of the installation enable comparisons of weathering rates of different materials, the effects of local climate or impacts of pollution. Being able to go to a local memorial or cemetery to compare diffrent structures brings a powerful local context to the learning. However we both have concerns that modern techniques that enable the creation of more elaborate memorials are actually setting the stage for more rapid deterioration. I will illustrate a cross section of our reseacrh and the impact it has had on

    Educating pre-registration nurses in clinical practice is a global issue. Within different countries problems exist in educating and supervising students in clinical practice and various models of clinical education are employed. In Wales, United Kingdom, this responsibility is divided between mentors, lecturer practitioners and link tutors. This paper reports on the third phase of a three-phase study in Wales to explore differences between mentors, lecturer practitioners and link tutors, and how they work together to assist students to integrate theory and practice. Four focus group interviews of National Health Service managers and Higher Education managers (n=22) were conducted. Qualitative content analysis revealed four themes: role characteristics and competencies, role differences, role conflict, and future options. The findings suggest a theory-practice continuum along which mentors, lecturer practitioners and link tutors occupy different positions. The article explores these different positions and offers suggestions for future role development.

SME is a characteristic of certain metal alloys that can change shape in response to temperature variations. In the late 1980s and early 1990s, Memry used its NASA-acquired expertise to produce a line of home and industrial safety products, and refined the technology in the mid-1990s. Among the new products they developed are three MemrySafe units which prevent scalding from faucets. Each system contains a small valve that reacts to temperature, not pressure. When the water reaches dangerous temperatures, the unit reduces the flow to a trickle; when the scalding temperature subsides, the unit restores normal flow. Other products are the FIRECHEK 2 and 4, heat-activated shutoff valves for industrial process lines, which sense excessive heat and cut off pneumatic pressure. The newest of these products is Memry's Demand Management Water Heater which shifts the electricity requirement from peak to off-peak demands, conserving energy and money.

    Bonding to tooth tissue can be achieved through an "etch&rinse," "self-etch" or "glass-ionomer" approach. In this paper, the basic bonding mechanism to enamel and dentin of these three approaches is demonstrated by means of ultramorphological and chemical characterization of tooth-biomaterial interfacial interactions. Furthermore, bond-strength testing and measurement of marginal-sealing effectiveness (the two most commonly employed methodologies to determine "bonding effectiveness" in the laboratory) are evaluated upon their value and relevance in predicting clinical performance. A new dynamic methodology to test biomaterial-tooth bonds in a fatigue mode is introduced with a recently developed micro-rotary fatigue-testing device. Eventually, today's adhesives will be critically weighted upon their performance in diverse laboratory studies and clinical trials. Special attention has been given to the benefits/drawbacks of an etch&rinse versus a self-etch approach and the long-term performance of these adhesives. Correlating data gathered in the laboratory with clinical results clearly showed that laboratory research CAN predict clinical effectiveness. Although there is a tendency to simplify bonding procedures, the data presented confirm that conventional three-step etch&rinse adhesives still perform most favorably and are most reliable in the long-term. Nevertheless, a self-etch approach may have the best future perspective. Clinically, when adhesives no longer require an "etch&rinse" step, the application time, and probably more importantly, the technique-sensitivity are substantially reduced. Especially "mild," two-step self-etch adhesives that bond through a combined micromechanical and chemical interaction with tooth tissue closely approach conventional three-step systems in bonding performance.

    Gold can be deposited as nanoparticles (NPs) of 2 to 5 nm in diameter on a variety of materials such as metal oxides and carbides, carbons, organic polymers and exhibits surprisingly high catalytic activities for many reactions in both gas and liquid phases. The mechanisms for the genesis of catalysis by gold NPs is discussed based on real powder catalysts and model single crystal catalysts for two simple reactions, low-temperature oxidation of CO in which gold NPs catalysts are exceptionally active and for dihydrogen dissociation in which gold NPs catalysts are still poorly active. For both the two reactions, it has been revealed that reactions take place at perimeter interfaces around gold NPs.

    It is pointed out that nearly all fatal aircraft accidents are preventable, and that most such accidents are due to human error. The present discussion is concerned with the results of a seven-year study of the data collected by the NASA Aviation Safety Reporting System (ASRS). The Aviation Safety Reporting System was designed to stimulate as large a flow as possible of information regarding errors and operational problems in the conduct of air operations. It was implemented in April, 1976. In the following 7.5 years, 35,000 reports have been received from pilots, controllers, and the armed forces. Human errors are found in more than 80 percent of these reports. Attention is given to the types of events reported, possible causal factors in incidents, the relationship of incidents and accidents, and sources of error in the data. ASRS reports include sufficient detail to permit authorities to institute changes in the national aviation system designed to minimize the likelihood of human error, and to insulate the system against the effects of errors.

    Review of recent progress in magnetospheric physics, in particular, in understanding the magnetospheric substorm. It is shown that a number of magnetospheric phenomena can now be understood by viewing the solar wind-magnetosphere interaction as an MHD dynamo; auroral phenomena are powered by the dynamo. Also, magnetospheric responses to variations of the north-south and east-west components of the interplanetary magnetic field have been identified. The magnetospheric substorm is entirely different from the responses of the magnetosphere to the southward component of the interplanetary magnetic field. It may be associated with the formation of a neutral line within the plasma sheet and with an enhanced reconnection along the line. A number of substorm-associated phenomena can be understood by noting that the new neutral line formation is caused by a short-circuiting of a part of the magnetotail current.

    1994-03-01

    1. Poultry disease research in the UK began recognisably in the 1920s, in consequence of the development of a national poultry industry of economic importance. 2. Increasing disease problems during the 1930s revealed the need for more research, resulting notably in the growth of the Poultry Department of the Central Veterinary Laboratory and the establishment of Houghton Poultry Research Station. 3. Continued growth of the egg industry and the introduction of the broiler industry in the 1950s stimulated increased disease research, much of it publicly funded, during the following two decades. 4. Changing government attitudes to agricultural research in the 1980s brought about far-reaching changes to the funding, organisation, nature and amount of disease research conducted. Arrangements for such research continue to evolve.

    PubMed

    2000-01-01

    Darwinian natural selection is the only factor in evolution that maintains and improves adaptation. It does so by favoring genes that enhance the genetic success of their bearers under historically prevalent conditions, and need not favor health or happiness or conformity to some universally normal state. It may favor unpleasant departures from medical normalcy if they contribute to long-term genetic success, either directly or as unavoidable costs of features that make such contributions. It is also blind to future consequences of current evolution, so that every evolving lineage accumulates historical legacies that may seriously constrain future adaptation. Examples of adaptive but unpleasant abnormality are found in infectious diseases and other instances of conflict (between the sexes, between parent and offspring, between competitors for limited resources). Examples of unfortunate historical legacies are found in limitations on numbers of parts (limbs, sense organs) and in the tight human birth passage. Adaptation is a more useful medical concept than normalcy, but the purpose of medicine is not to facilitate natural selection or uncritically encourage biological adaptations. Medical intervention may legitimately promote human values by frustrating adaptations (e.g., by anesthesia) or by seeking the grossly abnormal (e.g., birth through the abdomen rather than the vagina).

    Fowler, J. F.

    1984-01-01

    Models for predicting the total dose required to produce tolerable normal-tissue injury are becoming less empirical, more realistic, and more specific for different tissue reactions. The trend can be seen by the progression from the "cube root law", through Strandqvist's slope of 0.22, to NSD, TDF and CRE which have separate time and fraction number exponents, to the even better approximations which are now available. The dose-response formulae that can be used, with statistical legitimacy, to define the effect of fraction size (and number) include (1) the linear quadratic(LQ) model; (2) the two-component (TC) multi-target model; and (3) repair - misrepair models. The LQ model offers considerable convenience and requires only two parameters to be determined. The use of a new model often provides fresh insights. The LQ model has emphasized the difference between late and early normal-tissue dependence on dose per fraction which was first shown by exponents greater than the NSD slope of 0.24. Exponents of overall time, e.g. T0.11, yield the wrong shape of time curve, suggesting that most proliferation occurs early, although it really occurs after a delay depending on the turnover time of the tissue. The principles of better time factors are well known but actual values for human tissues are not well determined. Fortunately the time factors are usually small, especially for late reactions. Improved clinical results are being sought by hyperfractionation, by accelerated fractionation, or by continuous low dose rate irradiation as in interstitial implants. New clinical trials are investigating these approaches, which have been suggested by the accumulation of radiobiological data. PMID:6365141

    Ovarian cancer may be treated with radiation therapy, surgery, chemotherapy, or a combination. To evaluate the contribution of radiation therapy to patient management the cure rate must be estimated; data are presented suggesting that the 5-year survival rate provides a reasonable estimate of the cure rate. A study of patients treated since 1971 showed that stage and postoperative residuum could be used to divide patients into two subgroups, a poor prognosis group and a good prognosis group; a multifactorial grouping of patients in the good prognosis group who were treated postoperatively with radiation therapy only was further able to divide patients into low-risk, intermediate-risk, and high-risk groups. Studies of radiation therapy for different subgroups are discussed; abdominopelvic irradiation has been shown to improve survival for approximately one-third of patients with cancer of the ovary.

    Herbert Moran enlisted in the Royal Army Medical Corps early in World War I. His autobiography captures the impact of contemporary experience of wartime gunshot wounds, seen in vast numbers and with little understanding of the requirements of wartime surgery. Wounds of the face and brain were numerous, especially in trench fighting. In France, Germany, Britain and elsewhere, surgeons and dentists collaborated to repair mutilated faces and special centres were set up to facilitate this. The innovative New Zealand surgeon Harold Gillies developed his famous reconstructive techniques in the Queen's Hospital at Sidcup, with the help of dental surgeons, anaesthetists and medical artists. The treatment of brain wounds was controversial. Many surgeons, especially on the German side, advocated minimal primary operative surgery and delayed closure. Others advocated early exploration and immediate closure; among the first to do so was the Austro-Hungarian otologist Robert Bárány. In 1918, the pioneer American neurosurgeon Harvey Cushing published well-documented proof of the desirability of definitive operative management done as soon as possible. Few World War I surgeons developed their knowledge of plastic surgery, neurosurgery and oral surgery in post-war practice. An exception was Henry Newland, who went on to pioneer the development of these specialties in Australasia. After World War II, the French plastic surgeon Paul Tessier created the multidisciplinary subspecialty of craniomaxillofacial surgery, with the help of his neurosurgical colleague Gérard Guiot, and applied this approach to the correction of facial deformities. It has become evident that the new subspecialty requires appropriate training programs.

  5. Common sense and figures: the rhetoric of validity in medicine (Bradford Hill Memorial Lecture 1999).

    PubMed

    Horton, R

    2000-12-15

    Austin Bradford Hill was once a friend to The Lancet, but, as occasionally happens, friends fall out. The great legacy of his association with the journal, however, was Principles of Medical Statistics. As each edition was succeeded by another--the first in 1937, the last in 1991--he seemed to shift his view about the influence of statistical method on clinical practice from one of assured certainty to one of modest advantage. That change paralleled a move away from an emphasis on the importance of internal validity in the randomized trial to one of understanding the inescapably practical significance of generalizability. Writers on medical research have explored notions of external validity in various ways. One view, for example, is to seek a close correlation between the participants in a clinical trial and patients seen in practice. The argument goes that such a correspondence has to be made before any decision can be taken about whether to apply the result of that trial to the clinical setting. Another view, first worked out by the American logician Charles Sanders Peirce, is that one must simply rely on the informed guess, based on a reasonable estimate of the limits of extrapolation. The tensions between and implications of these two different approaches are worked through using the example of coronary stents. A solution is, perhaps, to write explicit rules of interpretation that provide a framework for judging the strength of a claim to applicability. Five questions are posed, which try to lay a foundation for such a framework.

    Taking the chemoselective hydrogenation of substituted nitroaromatics as a base case, it will be shown that it is possible to design improved and new catalysts by attacking the problem in a multidisciplinary way. By combining molecular modeling with in situ operando spectroscopy, and with micro-kinetic and isotopic studies, it is possible to determine how and where on the catalysts the reactant molecules interact. Then, materials synthesis methods can be applied to prepare catalysts with the desired surface active sites and their selective interaction with the reactants.

  7. The Otosclerosis Problem: including Reports of Two Cases Pathologically Examined (Dalby Memorial Lecture)

    PubMed Central

    Gray, Albert A.

    1934-01-01

    The essential causative factor of otosclerosis is a gradually increasing defect in the vasomotor mechanism which governs the nutrition of the structures of the organ of hearing as a whole. The axon reflexes are, of course, included in this vasomotor mechanism, and the stimulus which excites the vasomotor mechanism is sound and sound alone. Consequently the vestibular apparatus and the semicircular canals are unaffected in otosclerosis. There is no evidence whatever of any defect in any of the endocrine glands or their secretions in otosclerosis. Neither is there any evidence of any defect in the bone metabolism of the body. On the contrary the subjects of otosclerosis are, apart from their deafness, perfectly normal individuals with ordinary average health. The deafness of otosclerosis bears very little relationship to the extent of the disease in the bone. The deafness may be very severe when the stapes is hardly fixed at all. The severity of the tinnitus bears no relationship at all to the extent of the disease in the bone. The extent of the change in the bone bears very little relationship to the duration of the disease. The extent of the changes in the bone appears to depend upon the age of onset of the disease. The earlier in life that the otosclerosis begins, the more extensive will the bone lesion become. The deafness of otosclerosis is to a large extent functional, and is the result of the insufficient supply of blood to all the nerve-structures concerned in the perception of sound. The preponderance of women as subjects of otosclerosis is the result of the greater instability of their vasomotor system and the more frequent disturbances to which it is exposed. The changes in the bone show a remarkable bilateral symmetry even to minute details. This symmetrical distribution is readily explained by the writer's view of the causative factor of otosclerosis. The vasomotor nerves governing the nutrition of the organ of hearing are anatomically symmetrical like other nerve-structures in the body. If, therefore, structural changes occur as a result of defective functioning of those nerves, such structural changes will naturally be bilaterally symmetrical in their distribution.

    The classification of living things is both an acknowledgement of biological relationships and an identification of their differences. When Linnaeus, in 1735, published Systema Naturae, he set in place a system of biological classification that saw its apogee in the invention of binomial nomenclature: the description of every living thing being embodied simply in two names, (i.e. a genus and the species within it). Linnaeus built on the work of scientific forebears, of whom Nehemiah Grew (1641-1712) was one of the most influential. Grew was a surgeon-physician whose passionate interest was plant anatomy; his work led to the discovery and documentation of sexual dimorphism in plants. Grew's life and works are a witness to that philosophy which views nature as a continuum, a broad holistic entity in which discoveries in one biological field have ramifications in other areas. Grew allowed his scientific curiosity full rein, manifested the courage to publish his work and possessed the self-discipline to stand by the audit of his peers. Modern biological research and contemporary clinical practice owes much to the enlightenment engendered by the classification and nomenclature that developed from his work.

    General practitioner (GP) computing has its origins in the 1970s when the benefits of clinical coding and prescribing were demonstrated. During the early 1980s Dr James Read, working with Abies Informatics Ltd, developed the eponymous Read Codes, which were broader and more comprehensive than other schemes, yet intuitive and easy to use. In 1988 a joint working party of the Royal College of General Practitioners (RCGP) and the British Medical Association (BMA) recommended that the Read Codes be adopted nationally. The Read Codes have been used by almost all GPs in the UK since the mid-1990s. Many developments in general practice, including GP fundholding (where GPs held the budgets to commission elective care for their patients), the Quality and Outcomes Framework (QOF - pay for performance for improving chronic disease management) and GP commissioning (the current NHS reform in which primary care leads commissioning of services for their patients) would have been impossible without all GPs using a common clinical coding scheme. Systematized Nomenclature For Medicine - Clinical Terms (SNOMED CT) is a merger of the Read Codes with SNOMED RT - the original SNOMED reference terminology developed by the American College of Pathologists.

    An extensive review, with over 100 references, of the use of accelerator techniques in radiobiology is presented. Currently, beams of any stable isotope species up to uranium are available at kinetic energies of several hundred MeV/nucleon at the Berkeley Bevalac. The heavy ions hold interest for a broad spectrum of research because of their effectiveness in producing a series of major lesions in DNA along single particle tracks and because of the Bragg depth ionization properties that allow the precise deposition of highly localized doses deep in the human body. Heavy ions, when compared to low-LET radiation, have increased effectiveness for mammalian cell lethality, chromosome mutations, and cell transformation. The molecular mechanisms are not completely understood but appear to involve fragmentation and reintegration of DNA. Heavy ions do not require the presence of oxygen for producing their effects. Heavy ions are effective in delaying or blocking the cell division process. These radiobiological properties, combined with the ability to deliver highly localized internal doses, make accelerated heavy ions potentially important radiotherapeutic tools. Other novel approaches include the utilization of radioactive heavy beams as instant tracers. Heavy-ion radiography and microscopy respond to delicate changes in tissue electron density. The authors laboratory is in the process of proposing a research biomedical heavy-ion accelerator; the availability of such machines would greatly accelerate cancer and brain research with particle beams.

    1996-08-01

    Endovascular treatment techniques have already replaced some vascular operations. The likelihood is that new endovascular techniques involving stents and stented grafts will replace additional vascular operations. All these treatments involve the use of catheter-guidewire, balloon, and imaging modalities, particularly digital fluoroscopy. These modalities have already and will increasingly help to improve and simplify standard vascular operations such as thromboembolectomy, infrainguinal bypasses, and management of aneurysms and arteriovenous fistulas. Accordingly, vascular surgeons must become familiar with and use these endovascular methods and techniques. This can be accomplished in a variety of ways which includes working as part of a multidisciplinary vascular treatment group in which various specialists collaborate to provide the best, most cost-effective care to vascular disease patients.

    In a review of 1,000 carotid endarterectomies performed over a 20 year period, there was relief of transient ischemic attacks in approximately 85% of patients, an operative mortality of 1.3%, due almost exclusively to myocardial infarction, and a recurrent stenosis rate of 3.1%. Coexisting cardiac disease constitutes the greatest operative hazard. Continuous electroencephalographic monitoring is a reliable method of detecting inadequate cerebral perfusion during carotid cross clamping and for the selective use of a temporary inlying carotid shunt. An atherosclerotic plaque in the carotid system constitutes a greater risk than elsewhere in the peripheral arterial system and should not be considered an innocent lesion. Prophylactic carotid endarterectomy can be performed with almost no mortality and morbidity. Antiplatelet agents, while useful in reducing the incidence of transient ischemic attacks, do not seem to provide equal protection against stroke and death from stroke.

    Though advances in medical science have created improved therapies, often these are not widely provided throughout the health-care system. Also, there is growing recognition of the lack of safety in health-care delivery. The development of evidence-based, best practice, national guidelines has been encouraged to reduce unnecessary variation in care and for improving quality. Adoption of guidelines through local protocols has been disappointingly slow. This paper explores the parallel developments in safety and quality-of-care assessment, evidence-based medicine, guideline creation, and how development of national and international quality-improvement campaigns are promoting rapid change in care delivery processes. I discuss how this new opportunity can improve the quality of respiratory care and enhance the adoption of respiratory care protocols.

    The major focus of cancer immunology has shifted away from arguments about the validity of the immunosurveillance theory of cancer to the more basic question of tumor-specific antigens. Despite vast effort aimed at demonstrating such antigens, their existence in the generality of cancer remains unproven. Serological analysis of three tumor types, mouse leukemia, mouse sarcoma, and human malignant melanoma, has received most attention, and a rudimentary classification of the surface antigens expressed by these tumors has begun to emerge. The prime candidates for antigens that can be considered tumor specific are the few instances of Class 1 antigens that have now been serologically defined on mouse and human tumors. These antigens show an absolute restriction to individual tumors, not being demonstrable on any other normal or malignant cell type. Biochemical and genetic characterization of Class 1 antigens represents an essential next step in evaluating the significance of these antigens. The surprising features of the Thymus Leukemia (TL) antigens of the mouse provide insight into the genetic origin of another key class of tumor antigens, in this case antigens with characteristic properties of both differentiation antigens and tumor-specific antigens. In normal mice, TL antigens are restricted to cells in the thymus, and strains differ with regard to expression versus nonexpression of TL antigens. Genetic information for TL is universal in the mouse, however, as leukemias developing in mice that normally lack TL are found to express TL. What is clear from the past two decades of research in cancer immunology is that a far more detailed knowledge of surface antigens of tumor cells will be necessary before we can begin to assess the possibility of immunological control of cancer.

    Interplanetary space contains fluxes of fast moving atomic nuclei. The distribution of these reflects the atomic composition of the universe, and such particles may pose limitations for space flight and for life in space. Over the past 50 years, since the invention of Ernest Lawrence's cyclotron, advances in accelerator technology have permitted the acceleration of charged nuclei to very high velocities. Currently, beams of any stable isotope species up to uranium are available at kinetic energies of several hundred MeV/nucleon at the Berkeley Bevalac. Recently, new areas of particle physics research relating to the mechanisms of spallation and fission have opened up for investigation, and it is now realistic to search for nuclear super-dense states that might be produced in heavy nuclear collisions. The heavy ions hold interest for a broad spectrum of research because of their effectiveness in producing a series of major lesions in DNA along single particle tracks and because of the Bragg depth ionization properties that allow the precise deposition of highly localized doses deep in the human body. Individual heavy ions can also interrupt the continuity of membraneous regions in cells. Heavy ions, when compared to low-LET radiation, have increased effectiveness for mammalian cell lethality, chromosome mutations, and cell transformation. The molecular mechanisms are not completely understood but appear to involve fragmentation and reintegration of DNA. Cells attempt to repair these lesions, and many of the deleterious effects are due to misrepair or misrejoining of DNA. Heavy ions do not require the presence of oxygen for producing their effects, and hypoxic cells in necrotic regions have nearly the same sensitivity as cells in well-oxygenated tissues. Heavy ions are effective in delaying or blocking the cell division process. Heavy ions are also strong enhancers of viral-induced cell transformation, a process that requires integration of foreign DNA. Some cell lines, known to be radioresistant to X rays, have exhibited greater sensitivity to heavy ions. These radiobiological properties, combined with the ability to deliver highly localized internal doses, make accelerated heavy ions potentially important radiotherapeutic tools. Other novel approaches include the utilization of radioactive heavy beams as instant tracers. Heavy-ion radiography and microscopy respond to delicate changes in tissue electron density. Dose localization with helium ions has achieved excellent results for pituitary tumors, tumors adjacent to the spinal cord, and ocular melanomas. We are working on adapting silicon- and neon-ion beams for controlled therapy studies.(ABSTRACT TRUNCATED AT 400 WORDS)

  2. The fourth Okey memorial lecture. AIDS and HIV: the challenge for British drug services.

    PubMed

    1990-03-01

    British drug policies are undergoing a major reassessment and reformulation in response to problems raised by HIV disease and AIDS. The years from 1986 to 1989 are one of the key periods of crisis and transformation in the history of the British response to drug problems, with the emergence in current debate of a new public health paradigm of drug use. Drug policies can be analysed by examining their assumptions about the nature of (a) the problem (b) the drug user and (c) the task facing policy makers and practitioners; and their assumption about (d) the appropriate people to deal with the problem and (e) their relationships with clients. The emergent public health paradigm assumes that (a) the main problem with drug use is the injection of drugs (b) drug injectors are concerned about their health (c) the task is to promote change in health and risk behaviours (d) people dealing with the problem must be broadly skilled 'poly-drug workers' and (e) relationships with clients must be non-judgmental and 'user-friendly'.

    Delorenzi, A; Maza, F J; Suárez, L D; Barreiro, K; Molina, V A; Stehberg, J

    2014-01-01

    The idea that memories are not invariable after the consolidation process has led to new perspectives about several mnemonic processes. In this framework, we review our studies on the modulation of memory expression during reconsolidation. We propose that during both memory consolidation and reconsolidation, neuromodulators can determine the probability of the memory trace to guide behavior, i.e. they can either increase or decrease its behavioral expressibility without affecting the potential of persistent memories to be activated and become labile. Our hypothesis is based on the findings that positive modulation of memory expression during reconsolidation occurs even if memories are behaviorally unexpressed. This review discusses the original approach taken in the studies of the crab Neohelice (Chasmagnathus) granulata, which was then successfully applied to test the hypothesis in rodent fear memory. Data presented offers a new way of thinking about both weak trainings and experimental amnesia: memory retrieval can be dissociated from memory expression. Furthermore, the strategy presented here allowed us to show in human declarative memory that the periods in which long-term memory can be activated and become labile during reconsolidation exceeds the periods in which that memory is expressed, providing direct evidence that conscious access to memory is not needed for reconsolidation. Specific controls based on the constraints of reminders to trigger reconsolidation allow us to distinguish between obliterated and unexpressed but activated long-term memories after amnesic treatments, weak trainings and forgetting. In the hypothesis discussed, memory expressibility--the outcome of experience-dependent changes in the potential to behave--is considered as a flexible and modulable attribute of long-term memories. Expression seems to be just one of the possible fates of re-activated memories.

  6. Benzodiazepines and memory

    PubMed Central

    Roth, T.; Roehrs, T.; Wittig, R.; Zorick, F.

    1984-01-01

    1 Benzodiazepines possess anterograde amnesic properties, disrupting both short-term and long-term memory function. 2 The amount of amnesia is systematically related to dose effects and half-life differences among the benzodiazepines. 3 Memory deficits are found for episodic, semantic, and iconic memory function. 4 The deficits in long-term memory are probably the result of a disruption of consolidation of information in memory and not retrieval from memory. The disruption is produced by rapid sleep onset. 5 Thus the long-term amnesia is really a retrograde effect of sleep and not the anterograde effect of the drug. PMID:6151849

  7. Problems of neural memory

    NASA Astrophysics Data System (ADS)

    Mikaelian, Andrei L.

    2005-01-01

    The paper considers the neural memory of the human brain from the viewpoint of visual information processing. A model that explains the principle of data recording and storing, memory relaxation, associative remembering and other memory functions is offered. The model of associative memory is based on the methods of holography, "wave biochemistry" and autowaves. Brief consideration is given to the associative properties of holographic neural structures and the memory architecture using running chemical reactions. The paper also outlines the problem of developing artificial memory elements for restoring the brain functions and possible interface devices for coupling neurons to electronic systems.

  8. A comparison of traditional and engaging lecture methods in a large, professional-level course.

    PubMed

    Miller, Cynthia J; McNear, Jacquee; Metz, Michael J

    2013-12-01

    In engaging lectures, also referred to as broken or interactive lectures, students are given short periods of lecture followed by "breaks" that can consist of 1-min papers, problem sets, brainstorming sessions, or open discussion. While many studies have shown positive effects when engaging lectures are used in undergraduate settings, the literature surrounding use of the learning technique for professional students is inconclusive. The novelty of this study design allowed a direct comparison of engaging physiology lectures versus didactic lecture formats in the same cohort of 120 first-year School of Dentistry DMD students. All students were taught five physiological systems using traditional lecture methods and six physiological systems using engaging lecture methods. The use of engaging lectures led to a statistically significant higher average on unit exams compared with traditional didactic lectures (8.6% higher, P < 0.05). Furthermore, students demonstrated an improved long-term retention of information via higher scores on the comprehensive final exam (22.9% higher in engaging lecture sections, P < 0.05). Many qualitative improvements were also indicated via student surveys and evaluations, including an increased perceived effectiveness of lectures, decrease in distractions during lecture, and increased confidence with the material. The development of engaging lecture activities requires a significant amount of instructor preparation and limits the time available to provide traditional lectures. However, the positive results of this study suggest the need for a restructuring of the physiology curriculum to incorporate more engaging lectures to improve both the qualitative experiences and performance levels of professional students.

  16. Lecture recording system in anatomy: possible benefit to auditory learners.

    PubMed

    Bacro, Thierry R H; Gebregziabher, Mulugeta; Ariail, Jennie

    2013-01-01

    The literature reports that using Learning Recording Systems (LRS) is usually well received by students but that the pedagogical value of LRS in academic settings remains somewhat unclear. The primary aim of the current study is to document students' perceptions, actual pattern of usage, and impact of use of LRS on students' grade in a dental gross and neuroanatomy course. Other aims are to determine if students' learning preference correlated with final grades and to see if other factors like gender, age, overall academic score on the Dental Aptitude Test (DAT), lecture levels of difficulty, type of lecture, category of lecture, or teaching faculty could explain the impact, if any, of the use of LRS on the course final grade. No significant correlation was detected between the final grades and the variables studied except for a significant but modest correlation between final grades and the number of times the students accessed the lecture recordings (r=0.33 with P=0.01). Also, after adjusting for gender, age, learning style, and academic DAT, a significant interaction between auditory and average usage time was found for final grade (P=0.03). Students who classified themselves as auditory and who used the LRS on average for fewer than 10 minutes per access, scored an average final grade of 16.43 % higher than the nonauditory students using the LRS for the same amount of time per access. Based on these findings, implications for teaching are discussed and recommendations for use of LRS are proposed.

  9. Probing the Effectiveness of the Conventional Introductory Science Lecture

    NASA Astrophysics Data System (ADS)

    Slater, T. F.; Prather, E. E.

    2003-12-01

    For quite some time now, the repeated call for a more student-centered approach to teaching due to the ineffectiveness of lecture has been gaining prominence in the earth and space science teaching community. However, our extensive review of the literature suggests that this claim of ineffectiveness of lecture has not been validated in the context of the conventional introductory science course for non-science majors. At the beginning of a large-enrollment introductory astronomy survey course, we administered 68-multiple choice items as a pretest to 81 students. At the end of each lecture we administered the specific items related to that particular day's lecture a second time as a posttest. The average score on the 68 items administered as a pretest was 30 percent correct and the posttest average score was 52 percent correct. Although this does represent a statistically significant gain in scores, we judge this level of success to be insufficient for long term learning achievement. These results illustrate that instructor-centered strategies are largely ineffective at promoting meaningful conceptual gains on traditional earth and space topics presented to non-science majors. This work was supported by NSF CCLI #9952232 and NSF Geosciences Education #9907755.

  9. Just do it: flipped lecture, determinants and debate

    NASA Astrophysics Data System (ADS)

    Kensington-Miller, Barbara; Novak, Julia; Evans, Tanya

    2016-08-01

    This paper describes a case study of two pure mathematicians who flipped their lecture to teach matrix determinants in two large mathematics service courses (one at Stage I and the other at Stage II). The purpose of the study was to transform the passive lecture into an active learning opportunity and to introduce valuable mathematical skills, such as debate, argument and disagreement. The students were told in advance to use the online material to prepare, which had a short handout on matrix determinants posted, as the lesson would be interactive and would rely on them having studied this. At the beginning of the lesson, the two mathematicians worked together to model the skill of professional disagreement, one arguing for the cofactor expansion method and the other for the row reduction method. After voting for their preferred method, the students worked in small groups on examples to defend their choice. Each group elected a spokesperson and a political style debate followed as the students argued the pros and cons of each technique. Although one lecture does not establish whether the flipped lecture model is preferable for student instruction, the paper presents a case study for pursuing this approach and for further research on incorporating this style of teaching in Science, Technology, Engineering and Mathematics subjects.

  11. The ``RIPL'' Effect on Learning Gains in Lecture

    NASA Astrophysics Data System (ADS)

    Allen, Patricia E.; Cockman, John E.

    2009-11-01

    The main goal of the Redesigned Introductory Physics Lab (RIPL) project at Appalachian State is to improve student performance and attitudes in the algebra-based sequence. Modifications of the student lab experience were examined in terms of their impact on performance in the lecture portion, independent of the lecture instructor's pedagogical approach. Preliminary results for one lecture section, based on Modeling Instruction, indicate a large positive difference in all course measures for students in the redesigned lab compared to those in the more traditional lab offered by the department. On the other hand, FCI and other diagnostic scores show little difference between the two groups. While these measures indicate a discrepancy in the redesigned lab impact, an item-by-item analysis of the diagnostics reveals a rich story, one that can be used to improve both lecture and lab activities. In this paper, we examine some of the factors that strongly affect student performance, as well as the implications for the redesign process.

  14. Following student gaze patterns in physical science lectures

    NASA Astrophysics Data System (ADS)

    Rosengrant, David; Hearrington, Doug; Alvarado, Kerriann; Keeble, Danielle

    2012-02-01

    This study investigates the gaze patterns of undergraduate college students attending a lecture-based physical science class to better understand the relationships between gaze and focus patterns and student attention during class. The investigators used a new eye-tracking product; Tobii Glasses. The glasses eliminate the need for subjects to focus on a computer screen or carry around a backpack-sized recording device, thus giving an investigator the ability to study a broader range of research questions. This investigation includes what students focus on in the classroom (i.e. demonstrations, instructor, notes, board work, and presentations) during a normal lecture, what diverts attention away from being on task as well as what keeps a subject on task. We report on the findings from 8 subjects during physical science lectures designed for future elementary school teachers. We found that students tended not to focus on the instructor for most parts of the lecture but rather the information, particularly new information presented on PowerPoint slides. Finally, we found that location in the classroom also impacted students' attention spans due to more distractors.

  8. Analysis of Students' Eye Movement in Relation to Contents of Multimedia Lecture

    NASA Astrophysics Data System (ADS)

    Murakami, Masayuki; Kakusho, Koh; Minoh, Michihiko

    In this article, we report our analysis of how the students' eye movement is affected by the content of lecture in order to utilize as standard of selection of image for distance learning and WBT. We classified content of lecture into nine parts: introduction, presentation, explanation, illustration, assertion, query, reply, question, response.We analyzed students' eye movement in the multimedia lecture "Japanese Economics", which was distance lecture between Kyoto University and UCLA. As the result of analysis, we get the following characteristic of eye movement of each course process in practical lecture.Introduction; students gaze at lecturer at first in order to achieve advance organizer, and next look at material.Presentation; they mainly stare at material and sometimes peer at lecturer to complement lack of understanding with information given by lecturer.Explanation; staring time is longer than other course process categories, and students stare at the object which they regard as important.Illustration; students stare at material which offers main information source.Assertion; they gaze at lecturer because of interaction between lecturer and students.Question-and-answer; generally students look at speaker but in the case of "query" about material, they change their focuses on material and lecturer fast and by turns in order to get information of lecturer and material.And our research suggests the practical guide for our choice of image information.

    Sujarittham, T.; Emarat, N.; Arayathanitkul, K.; Sharma, M. D.; Johnston, I.; Tanamatayarat, J.

    2016-03-01

    As universities attempt to integrate active learning into their lectures, a range of strategies is emerging. Amongst the strategies is pre-prepared worksheets which students work through, facilitated by the lecturer. Despite the fact that worksheets have not yet been the subject of much research activity, there are instances of their use. Once such instance is by a pair of physics lecturers at Mahidol University, Thailand. The worksheets, called guided worksheets as they provide structure for students to take notes as the content in the lectures progresses, are prepared by the lecturers and have been in use since 2004. Evaluations showed that the guided worksheets met their intent but there were issues around certain topics which students found challenging. Concerted effort lead to the development of research based specialized guided worksheets for those topics that had issues. These specialized guided worksheets requiring substantially more interactions and student problem solving in line with active learning strategies, have been in use since 2012. This paper aims to describe the design of the specialized guided worksheets for the topic of electric field, and its evaluation. Pre- and post-tests were implemented over 2 years. The first was with guided worksheets with 260 students in 2011, and the second included specialized guided worksheets with 163 students in 2012. Gains on student understanding were higher in 2012 and students who were interviewed indicated that they found the specialized guided worksheets helpful for learning. The results indicate that the specialized guided worksheets made a difference in topics that students find challenging.

  16. Searching for repressed memory.

    PubMed

    McNally, Richard J

    2012-01-01

    This chapter summarizes the work of my research group on adults who report either repressed, recovered, or continuous memories of childhood sexual abuse (CSA) or who report no history of CSA. Adapting paradigms from cognitive psychology, we tested hypotheses inspired by both the "repressed memory" and "false memory" perspectives on recovered memories of CSA. We found some evidence for the false memory perspective, but no evidence for the repressed memory perspective. However, our work also suggests a third perspective on recovered memories that does not require the concept of repression. Some children do not understand their CSA when it occurs, and do not experience terror. Years later, they recall the experience, and understanding it as abuse, suffer intense distress. The memory failed to come to mind for years, partly because the child did not encode it as terrifying (i.e., traumatic), not because the person was unable to recall it.

A recent study in BMC Neuroscience has given new insights into the role of emotion in musical memory.

  2. Comparing biology majors from large lecture classes with TA-facilitated laboratories to those from small lecture classes with faculty-facilitated laboratories.

    PubMed

    Goodman, Barbara E; Koster, Karen L; Redinius, Patrick L

    2005-06-01

    The teaching faculty for this course sought to address their own concerns about the quality of student learning in an impersonal large lecture biology class for majors, the difficulties in getting to know each student by name, and difficulties in soliciting answers and reactions from the students during the lecture. Questions addressed by this study were, Do active-learning activities in a small and personal lecture setting enhance student learning more than active-learning activities in large impersonal lectures? and Are students more satisfied with an educational experience in a small and personal lecture setting? Based on faculty perceptions of how they best relate to their students, the prediction was that the students in the experimental group with small lecture classes and increased direct contact with the teaching faculty would learn physiological principles better than the students in the control group in the large impersonal lecture portion of the course. One of the laboratory sections of this large enrollment biology course was randomly selected to be taught with separate small lectures by the teaching faculty. In addition, the teaching faculty participated in the laboratory with these students during their experiments correlated with the lecture material. The students in both groups were compared by pre- and posttests of physiological principles, final course grades, and class satisfaction surveys.

  3. Monte Carlo Techniques for Nuclear Systems - Theory Lectures

    SciTech Connect

    Brown, Forrest B.

    2016-11-29

    These are lecture notes for a Monte Carlo class given at the University of New Mexico. The following topics are covered: course information; nuclear eng. review & MC; random numbers and sampling; computational geometry; collision physics; tallies and statistics; eigenvalue calculations I; eigenvalue calculations II; eigenvalue calculations III; variance reduction; parallel Monte Carlo; parameter studies; fission matrix and higher eigenmodes; doppler broadening; Monte Carlo depletion; HTGR modeling; coupled MC and T/H calculations; fission energy deposition. Solving particle transport problems with the Monte Carlo method is simple - just simulate the particle behavior. The devil is in the details, however. These lectures provide a balanced approach to the theory and practice of Monte Carlo simulation codes. The first lectures provide an overview of Monte Carlo simulation methods, covering the transport equation, random sampling, computational geometry, collision physics, and statistics. The next lectures focus on the state-of-the-art in Monte Carlo criticality simulations, covering the theory of eigenvalue calculations, convergence analysis, dominance ratio calculations, bias in Keff and tallies, bias in uncertainties, a case study of a realistic calculation, and Wielandt acceleration techniques. The remaining lectures cover advanced topics, including HTGR modeling and stochastic geometry, temperature dependence, fission energy deposition, depletion calculations, parallel calculations, and parameter studies. This portion of the class focuses on using MCNP to perform criticality calculations for reactor physics and criticality safety applications. It is an intermediate level class, intended for those with at least some familiarity with MCNP. Class examples provide hands-on experience at running the code, plotting both geometry and results, and understanding the code output. The class includes lectures & hands-on computer use for a variety of Monte Carlo calculations

  4. Conflict of Learning Styles: University Science Lectures in the Sultanate of Oman

    Arden-Close, Christopher

    1999-12-01

    This article examines the differing learning styles found in western lecturers and Omani students in science lectures in the Sultanate of Oman. Oman is a country which modernized very recently, and students there were encountering western lecturers and lecturing methods for the first time. The western lecturers found the Omani approach to science, which they characterized as memorization deficient and wished to introduce a problem-solving approach. However, it is argued that some memorization occurs in all learning of science everywhere, that the Omani approach has its merits, and that a major problem in these lectures was the lack of knowledge of Omani and Arabic culture in the lecturers. It is argued that all learning takes place by matching new knowledge and methods with previous ones, and that to successfully lecture to the Omani students the lecturers would need to research further into ways in which their approach could have built on, rather than replaced entirely, the Omani approach. The article is based on interviews with the lecturers and extracts from the lectures, which were recorded and transcribed by the writer.

  5. Learning to lecture: exploring the skills, strategies, and practices of new teachers in nursing education.

    A common experience among new teachers is learning how to lecture. Lecturing is a skill, a strategy, and a practice. As a skill, lecturing is learned over time. For example, teachers learn how to select content to hold students' attention. Lecturing is a strategy teachers use when they want to efficiently cover a great deal of content. In addition, it is a practice that has shared meanings, practical knowledge, and language. Exploring how new teachers learn to lecture clarifies the nature, meaning, and significance of lecturing in nursing education. The study described in this article used Heideggerian hermeneutic analyses to explicate the common experiences (i.e., themes and patterns) of new nurse teachers. Learning to Lecture as a theme is described, and implications for teacher preparation and future research are offered.

    The purpose of this paper is to show that immunological memory is an associative and robust memory that belongs to the class of sparse distributed memories. This class of memories derives its associative and robust nature by sparsely sampling the input space and distributing the data among many independent agents. Other members of this class include a model of the cerebellar cortex and Sparse Distributed Memory (SDM). First we present a simplified account of the immune response and immunological memory. Next we present SDM, and then we show the correlations between immunological memory and SDM. Finally, we show how associative recall in the immune response can be both beneficial and detrimental to the fitness of an individual.

    Nowicki, Dimitri; Siegelmann, Hava

    2010-01-01

    This paper introduces a new model of associative memory, capable of both binary and continuous-valued inputs. Based on kernel theory, the memory model is on one hand a generalization of Radial Basis Function networks and, on the other, is in feature space, analogous to a Hopfield network. Attractors can be added, deleted, and updated on-line simply, without harming existing memories, and the number of attractors is independent of input dimension. Input vectors do not have to adhere to a fixed or bounded dimensionality; they can increase and decrease it without relearning previous memories. A memory consolidation process enables the network to generalize concepts and form clusters of input data, which outperforms many unsupervised clustering techniques; this process is demonstrated on handwritten digits from MNIST. Another process, reminiscent of memory reconsolidation is introduced, in which existing memories are refreshed and tuned with new inputs; this process is demonstrated on series of morphed faces.

    Shared virtual memory (SVM) is a virtual memory layer with a single address space on top of a distributed real memory on parallel computers. We examine the behavior and performance of SVM running a parallel program with medium-grained, loop-level parallelism on top of it. A simulator for the underlying parallel architecture can be used to examine the behavior of SVM more deeply. The influence of several parameters, such as the number of processors, page size, cold or warm start, and restricted page replication, is studied.

    There are certain classes of resistors, capacitors, and inductors that, when subject to a periodic input of appropriate frequency, develop hysteresis loops in their characteristic response. Here we show that the hysteresis of such memory elements can also be induced by white noise of appropriate intensity even at very low frequencies of the external driving field. We illustrate this phenomenon using a physical model of memory resistor realized by TiO(2) thin films sandwiched between metallic electrodes and discuss under which conditions this effect can be observed experimentally. We also discuss its implications on existing memory systems described in the literature and the role of colored noise.

    Objectives Teachers often wonder what students are doing during lectures, behind their computers, mobile phones and other digital tools. This study aimed to document the type of tools used during lectures by nursing students and what they do with them. Methods We carried out a descriptive, prospective, multicentre study including 1446 nursing students in Alsace (France). The students filled in an anonymous questionnaire at the end of a lesson they had just attended. Results 99% of the students had taken at least one digital tool to the lesson. 90% had a mobile phone with them. It was mainly used for entertainment (particularly for sending and/or receiving text messages and consulting emails). 52% had a laptop with them. It was essentially used for academic tasks (taking notes, working on other teaching units or revising for exams). Conclusion Most nursing students take a phone or laptop to lectures with them with the intention of using them for entertainment and learning respectively. These results could guide training establishments in drafting their institutional policy concerning the use of digital tools in class. PMID:27812170

    To investigate the memory bistable mechanisms of organic memory devices, the structure of [top Au anode/9,10-di(2-naphthyl)anthracene (ADN) active layer/bottom Au cathode] was deposited using a thermal deposition system. The Au atoms migrated into the ADN active layer was observed from the secondary ion mass spectrometry. The density of 9.6×1016 cm-3 and energy level of 0.553 eV of the induced trapping centers caused by the migrated Au atoms in the ADN active layer were calculated. The induced trapping centers did not influence the carrier injection barrier height between Au and ADN active layer. Therefore, the memory bistable behaviors of the organic memory devices were attributed to the induced trapping centers. The energy diagram was established to verify the mechanisms.

    PubMed

    Rothen, Nicolas; Meier, Beat

    2014-01-01

    Prospective memory involves the self-initiated retrieval of an intention upon an appropriate retrieval cue. Cue identification can be considered as an orienting reaction and may thus trigger a psychophysiological response. Here we present two experiments in which skin conductance responses (SCRs) elicited by prospective memory cues were compared to SCRs elicited by aversive stimuli to test whether a single prospective memory cue triggers a similar SCR as an aversive stimulus. In Experiment 2 we also assessed whether cue specificity had a differential influence on prospective memory performance and on SCRs. We found that detecting a single prospective memory cue is as likely to elicit a SCR as an aversive stimulus. Missed prospective memory cues also elicited SCRs. On a behavioural level, specific intentions led to better prospective memory performance. However, on a psychophysiological level specificity had no influence. More generally, the results indicate reliable SCRs for prospective memory cues and point to psychophysiological measures as valuable approach, which offers a new way to study one-off prospective memory tasks. Moreover, the findings are consistent with a theory that posits multiple prospective memory retrieval stages.

  10. Human learning and memory.

    PubMed

    Johnson, M K; Hasher, L

    1987-01-01

    There have been several notable recent trends in the area of learning and memory. Problems with the episodic/semantic distinction have become more apparent, and new efforts have been made (exemplar models, distributed-memory models) to represent general knowledge without assuming a separate semantic system. Less emphasis is being placed on stable, prestored prototypes and more emphasis on a flexible memory system that provides the basis for a multitude of categories or frames of reference, derived on the spot as tasks demand. There is increasing acceptance of the idea that mental models are constructed and stored in memory in addition to, rather than instead of, memorial representations that are more closely tied to perceptions. This gives rise to questions concerning the conditions that permit inferences to be drawn and mental models to be constructed, and to questions concerning the similarities and differences in the nature of the representations in memory of perceived and generated information and in their functions. There has also been a swing from interest in deliberate strategies to interest in automatic, unconscious (even mechanistic!) processes, reflecting an appreciation that certain situations (e.g. recognition, frequency judgements, savings in indirect tasks, aspects of skill acquisition, etc) seem not to depend much on the products of strategic, effortful or reflective processes. There is a lively interest in relations among memory measures and attempts to characterize memory representations and/or processes that could give rise to dissociations among measures. Whether the pattern of results reflects the operation of functional subsystems of memory and, if so, what the "modules" are is far from clear. This issue has been fueled by work with amnesics and has contributed to a revival of interaction between researchers studying learning and memory in humans and those studying learning and memory in animals. Thus, neuroscience rivals computer science as a

    The idea that memory is not a single mental faculty has a long and interesting history but became a topic of experimental and biologic inquiry only in the mid-20th century. It is now clear that there are different kinds of memory, which are supported by different brain systems. One major distinction can be drawn between working memory and long-term memory. Long-term memory can be separated into declarative (explicit) memory and a collection of nondeclarative (implicit) forms of memory that include habits, skills, priming, and simple forms of conditioning. These memory systems depend variously on the hippocampus and related structures in the parahippocampal gyrus, as well as on the amygdala, the striatum, cerebellum, and the neocortex. This work recounts the discovery of declarative and nondeclarative memory and then describes the nature of declarative memory, working memory, nondeclarative memory, and the relationship between memory systems.

    A general algorithm for testing digital computer memory is presented. The test checks that (1) every bit can be cleared and set in each memory work, and (2) bits are not erroneously cleared and/or set elsewhere in memory at the same time. The algorithm can be applied to any size memory block and any size memory word. It is concise and efficient, requiring the very few cycles through memory. For example, a test of 16-bit-word-size memory requries only 384 cycles through memory. Approximately 15 seconds were required to test a 32K block of such memory, using a microcomputer having a cycle time of 133 nanoseconds.

    Memory for antigen is a defining feature of adaptive immunity. Antigen-specific lymphocyte populations show an increase in number and function after antigen encounter and more rapidly re-expand upon subsequent antigen exposure. Studies of immune memory have primarily focused on effector B cells and T cells with microbial specificity, using prime challenge models of infection. However, recent work has also identified persistently expanded populations of antigen-specific regulatory T cells that protect against aberrant immune responses. In this Review, we consider the parallels between memory effector T cells and memory regulatory T cells, along with the functional implications of regulatory memory in autoimmunity, antimicrobial host defence and maternal fetal tolerance. In addition, we discuss emerging evidence for regulatory T cell memory in humans and key unanswered questions in this rapidly evolving field. PMID:26688349
